LONDON – Weight loss, lipid reductions, and “robust improvements” in lipid species associated with nonalcoholic fatty liver disease were achieved in patients who were treated with pemvidutide in a first-in-human, phase 1 clinical trial reported at the annual International Liver Congress, sponsored by the European Association for the Study of the Liver.

The presenting study investigator, Stephen A. Harrison, MD, said that pemvidutide, which is also being developed for the treatment of obesity, appeared to be well tolerated. There were no serious or severe adverse events, and no patient had to discontinue treatment because of side effects.

Overall, “pemvidutide represents a promising new agent,” said Dr. Harrison, medical director of Pinnacle Research in San Antonio, Texas.
 

Dual incretin effect

Pemvidutide is a “balanced” dual agonist of glucagon-like peptide 1 (GLP-1) and glucagon, Dr. Harrison explained in his oral abstract.

“With glucagon, we are working to drive energy expenditure up, and with GLP-1, we’re decreasing food intake,” Dr. Harrison said.

What might set pemvidutide apart from other incretins lies within its structure, Dr. Harrison suggested. The structure has two main regions – one with greater GLP-1 specificity and the other with greater glucagon specificity, and these two areas are linked by a propriety technology called a EuPort^™ domain. This is an area which allows the drug to bind to albumin, which increases its serum half-life and enables weekly dosing while slowing its entry into the bloodstream.

“Ultimately, we think that this has impacts, hypothetically, on tolerability and potentially mitigating the need for dose escalation,” said Dr. Harrison.
 

Weight loss results

The phase 1 study Dr. Harrison presented had a randomized, double-blind, placebo-controlled design with single and multiple ascending doses (SAD/MAD) of pemvidutide being tested. He presented data on the MAD phase only, noting that the SAD phase had been used to determine what doses to use in the latter.

Seventy individuals with a body mass index of between 25 and 40 kg/m² were recruited and 34 of these were enrolled in the MAD phase of the study. Three doses of pemvidutide were used, given subcutaneously once a week for 12 weeks: Seven participants received 1.2 mg, 9 were given 1.8 mg, 11 had 2.4 mg, and 7 subjects were treated with placebo. Dr. Harrison noted that there were no caloric restrictions in the trial and no lifestyle modifications or interventions.

The average age of study participants ranged from 27 to 35 years and the mean BMI was 30-31 kg/m² across each group, with their lipid parameters in the upper range of normal.

Clear weight loss reductions were seen across all the pemvidutide groups versus placebo, with the greatest percentage changes in weight loss seen with the two higher doses used. At week 12, there was a 4.9%, 10.3% and 9.0% weight loss in the 1.2-mg, 1.8-mg and 2.4-mg pemvidutide groups compared to 1.6% in placebo-treated individuals.

All patients in the 1.8-mg group achieved a 5% or greater weight loss, Dr. Harrison observed, but there “was a plateauing” effect with the 2.4-mg dose with 89% of patients achieving this target. In comparison, a third of patients on the lowest dose and 20% of those on placebo achieved this target.

The trajectory of weight loss seen in the trial suggests that “the rate of weight loss would continue beyond 12 weeks if we were to continue the therapy” Dr. Harrison said.
 

Lipid changes and liver fat reductions

Levels of serum lipids from baseline to week 12 fell to a greater extent with pemvidutide treatment than with placebo, in the range of –27% for total cholesterol in the two highest dose groups, –25% for LDL-cholesterol for those groups, –37% for triglycerides for the 1.2- and 1.8-mg groups, and reductions in apolipoprotein B were seen.

“We saw an initial decline in HDL [high-density lipoprotein],” Dr. Harrison said, noting that “this is consistent with prior studies looking at rapid weight loss, and over time, this mitigates as you continue to treat at least based on other mechanisms of action or other drugs with similar mechanisms.”

Pemvidutide treatment was also associated with increased lipid oxidation and decreased lipid synthesis, and “there was a robust decrease in lipids implicated in NASH inflammation,” Dr. Harrison pointed out.

Importantly, in five of eight participants who had high levels of liver fat at baseline – defined as a 5% or greater magnetic resonance imaging–derived proton-density-fat-fraction (MRI-PDFF) – showed a decrease to undetectable limits (1.5% or less). This was a greater than 90% reduction in liver fat, Dr. Harrison said. All five patients were in the 1.8-mg and 2.4-mg groups.

As for side effects, these were “predominantly upper GI, with nausea and vomiting.” These were mild in most cases, but he pointed out that five patients treated with the 1.8-mg dose experienced moderate nausea and three experienced moderate vomiting. Mild diarrhea and constipation were also seen in two of patients given this dose but was not reported in any of the other groups.

During the discussion following the presentation, it was pointed out that there was no clear dose-dependent effect considering the 1.8-mg dose seemed to have a stronger effect in some areas than the 2.4-mg dose. That’s a fair point, Dr. Harrison responded, reiterating it was a small study with a short treatment duration, but that there did look like a plateauing effect, “at least in patients with a mean BMI of between 30 and 31.”

Dr. Harrison was asked about potential effects on insulin levels and if that was a worry because, if glucagon is stimulated, it could increase insulin. That in turn might encourage insulin resistance and promote worse outcomes.

“If you look outside of just this program, glucagon agonism has been dosed in a lot of patients over time, and we haven’t seen that,” Dr. Harrison replied. Pemvidutide is an agonist rather than antagonist, so perhaps the [nonalcoholic steatohepatitis]–inducing effects seen before with glucagon antagonism won’t occur, he suggested.

Dr. Harrison disclosed ties to Altimmune (the study sponsor), Akero, Axcella, Bristol Myers Squibb, Cirius, CiVi Biopharma, Conatus, Corcept, CymaBay, Enyo, Galectin, Genentech, Genfit, Gilead, Hepion, Hightide, HistoIndex, Intercept, Madrigal, Metacrine, NGM Bio, Novartis, Novo Nordisk, NorthSea, Pfizer, Sagimet, Viking, and 89Bio.

LONDON – Around the world, nonalcoholic fatty liver disease (NAFLD) has driven an increase in deaths from liver cancer over the past decade, overtaking alcoholic liver disease, hepatitis B, and hepatitis C, according to an analysis of the Global Burden of Disease Study 2019.

A global rise in liver cancer deaths and chronic liver disease reflects changes in underlying health patterns, said Zobair Younossi, MD, MPH, professor and chair, department of medicine, Inova Fairfax Medical Campus, Falls Church, Va., who presented the analysis at the International Liver Congress (ILC) 2022.

“NAFLD and NASH [nonalcoholic steatohepatitis] are rapidly becoming the main causes of cirrhosis and liver cancer in the world,” Dr. Younossi told this news organization. “We have known about the increasing prevalence for some time, but now the outcomes in terms of mortality are catching up,” he said.

“The bottom line of this study is that the burden of this disease [NAFLD] is going up, and it will be the most important disease of the next decade or so,” he said, adding that “the largest annual percentage increase in rates of mortality from liver cancer or chronic liver disease cirrhosis is related to NAFLD.”

Specifically, during the decade of 2009-2019, the annual percent change (APC) of +1.33% in the global liver cancer death rate was driven by the fact that the APC for NAFLD was +2.47%. By comparison, the APC for alcoholic liver disease was +1.91%; for hepatitis B, the APC was +0.21%; and for hepatitis C, the APC was +1.12%.

Aleksander Krag, MD, PhD, professor and senior consultant of hepatology and director of Odense Liver Research Centre at SDU and Odense University Hospital, Denmark, who chaired the session in which this presentation was a part, acknowledged the importance of recognizing the contribution of NAFLD to liver cancer mortality.

“Liver diseases are on the rise. They are the fastest rising cause of death in the United Kingdom, faster than heart disease and other cancers. NAFLD in particular is the fastest growing cause of liver cancer, and the leading cause in France and the United States,” he remarked.

Dr. Krag also highlighted the costs of disease management.

“Managing fatty liver disease in Europe is estimated at €35 billion in direct health care, so we need to do something now,” he stressed.

“The global burden of NAFLD is so high that we need both prevention and treatment tools,” Dr. Krag said. “Change to lifestyle is a ‘no-brainer’ and costs governments very little. For the sake of our young people, we need to take this very seriously. At a political level, we can easily implement this, for example, by banning junk food advertisements, but also educating young people and their families. Good drugs will also help.”
 

NAFLD: The liver manifestation of type 2 diabetes

About 25%-30% of the global population have NAFLD, and 3%-5% have NASH. Dr. Younossi highlighted that the U.S. transplant database shows that NAFLD was the second indication for all liver transplants in the country. NAFLD also was a leading cause of liver transplants for patients with hepatocellular carcinoma.

There are around two billion cases of chronic liver disease globally, he said. He noted that over time, there has been an increase in all kinds of liver diseases, as reflected in the annual percent change.

“The global epidemic of obesity and type 2 diabetes is driving the rise in NAFLD, but even among lean people, the prevalence of NAFLD is around 9%,” Dr. Younossi said. “Alongside the eye and kidney complications of diabetes, this is the liver manifestation of type 2 diabetes.”

To assess global liver disease and death, Dr. Younossi and his colleagues turned to the Global Burden of Disease Study, which gathered data from around 7,000 investigators located across 22 different regions of the world, comprising 156 countries.

They calculated the incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) in relation to liver cancer and chronic liver disease, including the APC. They linked the data to changes in four liver diseases: NAFLD, alcoholic liver disease, hepatitis B infection, and hepatitis C infection.

The cases of NAFLD reported in the study had been diagnosed by ultrasound or other imaging. Importantly, the prevalence of NAFLD was adjusted for alcohol use in the various national populations, explained Dr. Younossi.

In 2019, they reported that globally, the overall prevalence of liver disease reached 1.69 billion (liver cancer, 0.04%; chronic liver disease, 99.96%), with an incidence of 2.59 million (liver cancer, 20.7%; chronic liver disease, 79.3%), mortality of 1.95 million (liver cancer, 24.8%; chronic liver disease, 75.3%), and DALYs of 58.7 million (liver cancer, 21.3%; chronic liver disease, 78.7%).

Between 2009 and 2019, deaths from liver cancer rose by 27.2%, and deaths from chronic liver disease rose by 10.6%. DALYs from liver cancer rose by 21.9%, and DALYs from chronic liver disease were up by 5.1%.

In contrast to the increase in liver cancer deaths, deaths from chronic liver disease decreased (APC, –0.18%). The decrease was driven by a decrease in hepatitis B (APC, –1.83%). APCs for hepatitis C (+0.37%), alcoholic liver disease (+0.45%), and NAFLD (+1.33%) increased.

“The burden of hepatitis B–related mortality has decreased because we have been so good at vaccinating people,” Dr. Younossi remarked.
 

NAFLD ‘exploding’ in Middle East, North Africa, and East Asia

The increase in NAFLD has been seen in all regions of the world, but a breakdown by region shows that NAFLD is primarily “exploding” with highest prevalence and mortality in the Middle East (mostly Egypt, Iran, and Turkey), North Africa, and East Asia, said Dr. Younossi. In addition, there are large increases in the West and South America.

“We knew that the prevalence was high in the Middle East, but we now know that mortality is also high, so we are connecting these data,” said Dr. Younossi.
 

Awareness lacking

Dr. Younossi pressed the fact that awareness among the general population, primary care providers, and policymakers is very low. “From my perspective, raising awareness of NAFLD is the number one priority, and that is the value of this study.”

He added that more people will become aware as testing becomes more manageable.

“There are some noninvasive tests being developed, so in the future, we won’t have to do liver biopsies to diagnose these patients,” he said. “Currently, there are some excellent treatments being developed.”

“The WHO [World Health Organization] does not mention NAFLD as an important noncommunicable disease, and this too has to change,” Dr. Younossi added.

Dr. Younossi has received research funds and/or has consulted for Abbott, Allergan, Bristol-Myers Squibb, Echosens, Genfit, Gilead Sciences, Intercept, Madrigal, Merck, and Novo Nordisk. Dr. Krag has disclosed no relevant financial relationships.

LONDON – Around the world, nonalcoholic fatty liver disease (NAFLD) has driven an increase in deaths from liver cancer over the past decade, overtaking alcoholic liver disease, hepatitis B, and hepatitis C, according to an analysis of the Global Burden of Disease Study 2019.

A global rise in liver cancer deaths and chronic liver disease reflects changes in underlying health patterns, said Zobair Younossi, MD, MPH, professor and chair, department of medicine, Inova Fairfax Medical Campus, Falls Church, Va., who presented the analysis at the International Liver Congress (ILC) 2022.

“NAFLD and NASH [nonalcoholic steatohepatitis] are rapidly becoming the main causes of cirrhosis and liver cancer in the world,” Dr. Younossi told this news organization. “We have known about the increasing prevalence for some time, but now the outcomes in terms of mortality are catching up,” he said.

“The bottom line of this study is that the burden of this disease [NAFLD] is going up, and it will be the most important disease of the next decade or so,” he said, adding that “the largest annual percentage increase in rates of mortality from liver cancer or chronic liver disease cirrhosis is related to NAFLD.”

Specifically, during the decade of 2009-2019, the annual percent change (APC) of +1.33% in the global liver cancer death rate was driven by the fact that the APC for NAFLD was +2.47%. By comparison, the APC for alcoholic liver disease was +1.91%; for hepatitis B, the APC was +0.21%; and for hepatitis C, the APC was +1.12%.

Aleksander Krag, MD, PhD, professor and senior consultant of hepatology and director of Odense Liver Research Centre at SDU and Odense University Hospital, Denmark, who chaired the session in which this presentation was a part, acknowledged the importance of recognizing the contribution of NAFLD to liver cancer mortality.

“Liver diseases are on the rise. They are the fastest rising cause of death in the United Kingdom, faster than heart disease and other cancers. NAFLD in particular is the fastest growing cause of liver cancer, and the leading cause in France and the United States,” he remarked.

Dr. Krag also highlighted the costs of disease management.

“Managing fatty liver disease in Europe is estimated at €35 billion in direct health care, so we need to do something now,” he stressed.

“The global burden of NAFLD is so high that we need both prevention and treatment tools,” Dr. Krag said. “Change to lifestyle is a ‘no-brainer’ and costs governments very little. For the sake of our young people, we need to take this very seriously. At a political level, we can easily implement this, for example, by banning junk food advertisements, but also educating young people and their families. Good drugs will also help.”
 

NAFLD: The liver manifestation of type 2 diabetes

About 25%-30% of the global population have NAFLD, and 3%-5% have NASH. Dr. Younossi highlighted that the U.S. transplant database shows that NAFLD was the second indication for all liver transplants in the country. NAFLD also was a leading cause of liver transplants for patients with hepatocellular carcinoma.

There are around two billion cases of chronic liver disease globally, he said. He noted that over time, there has been an increase in all kinds of liver diseases, as reflected in the annual percent change.

“The global epidemic of obesity and type 2 diabetes is driving the rise in NAFLD, but even among lean people, the prevalence of NAFLD is around 9%,” Dr. Younossi said. “Alongside the eye and kidney complications of diabetes, this is the liver manifestation of type 2 diabetes.”

To assess global liver disease and death, Dr. Younossi and his colleagues turned to the Global Burden of Disease Study, which gathered data from around 7,000 investigators located across 22 different regions of the world, comprising 156 countries.

They calculated the incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) in relation to liver cancer and chronic liver disease, including the APC. They linked the data to changes in four liver diseases: NAFLD, alcoholic liver disease, hepatitis B infection, and hepatitis C infection.

The cases of NAFLD reported in the study had been diagnosed by ultrasound or other imaging. Importantly, the prevalence of NAFLD was adjusted for alcohol use in the various national populations, explained Dr. Younossi.

In 2019, they reported that globally, the overall prevalence of liver disease reached 1.69 billion (liver cancer, 0.04%; chronic liver disease, 99.96%), with an incidence of 2.59 million (liver cancer, 20.7%; chronic liver disease, 79.3%), mortality of 1.95 million (liver cancer, 24.8%; chronic liver disease, 75.3%), and DALYs of 58.7 million (liver cancer, 21.3%; chronic liver disease, 78.7%).

Between 2009 and 2019, deaths from liver cancer rose by 27.2%, and deaths from chronic liver disease rose by 10.6%. DALYs from liver cancer rose by 21.9%, and DALYs from chronic liver disease were up by 5.1%.

In contrast to the increase in liver cancer deaths, deaths from chronic liver disease decreased (APC, –0.18%). The decrease was driven by a decrease in hepatitis B (APC, –1.83%). APCs for hepatitis C (+0.37%), alcoholic liver disease (+0.45%), and NAFLD (+1.33%) increased.

“The burden of hepatitis B–related mortality has decreased because we have been so good at vaccinating people,” Dr. Younossi remarked.
 

NAFLD ‘exploding’ in Middle East, North Africa, and East Asia

The increase in NAFLD has been seen in all regions of the world, but a breakdown by region shows that NAFLD is primarily “exploding” with highest prevalence and mortality in the Middle East (mostly Egypt, Iran, and Turkey), North Africa, and East Asia, said Dr. Younossi. In addition, there are large increases in the West and South America.

“We knew that the prevalence was high in the Middle East, but we now know that mortality is also high, so we are connecting these data,” said Dr. Younossi.
 

Awareness lacking

Dr. Younossi pressed the fact that awareness among the general population, primary care providers, and policymakers is very low. “From my perspective, raising awareness of NAFLD is the number one priority, and that is the value of this study.”

He added that more people will become aware as testing becomes more manageable.

“There are some noninvasive tests being developed, so in the future, we won’t have to do liver biopsies to diagnose these patients,” he said. “Currently, there are some excellent treatments being developed.”

“The WHO [World Health Organization] does not mention NAFLD as an important noncommunicable disease, and this too has to change,” Dr. Younossi added.

Dr. Younossi has received research funds and/or has consulted for Abbott, Allergan, Bristol-Myers Squibb, Echosens, Genfit, Gilead Sciences, Intercept, Madrigal, Merck, and Novo Nordisk. Dr. Krag has disclosed no relevant financial relationships.

Life expectancy in the United States plateaued in recent years, and persistent racial disparities vary by state, according to an analysis of death records and Census data from 1990 to 2019.

“Life expectancy is an important measure of the health of the entire population,” corresponding author Gregory Roth, MD, a cardiologist at the University of Washington, Seattle, said in an interview. “We know race, ethnicity and where you live all affect health, but we wanted to look at the long arc over many decades to understand where subpopulations have been, and where they are headed. Also, it is important to understand how race and place interact, so we looked at race/ethnicity groups within each state to see where disparities exist that need to be addressed.”

In the study, published in Annals of Internal Medicine, researchers led by Catherine O. Johnson, PhD, of the University of Washington, Seattle, reviewed data from 23 states, using regression models based on Census data and deidentified death records. They examined life expectancy for subgroups of individuals reporting Hispanic, non-Hispanic Black, or non-Hispanic White race or ethnicity.

Overall, most states showed an improvement in life expectancy between 1990 and 2019. For women, the mean life expectancy across states increased from 79.3 years in 1990 to 81.3 years in 2019. For men, the mean life expectancy across states increased from 72.6 years in 1990 to 76.3 years in 2019.

However, the researchers found significant disparities across the three racial subgroups between and within states when life expectancy was examined by race/ethnicity, independent of the average life expectancy for an entire state overall. They defined disparity as the difference in life expectancy between states for those in different racial/ethnic groups.

Without considering race/ethnicity, disparities in life expectancy across states decreased from 8.0 years and 12.2 years in 1990 to 7.9 and 7.8 years in 2019, for females and males, respectively.

When race/ethnicity was taken into account, disparities in life expectancy decreased, but the differences across states were greater than when race was not considered; 20.7 years for females and 24.5 years for males in 1990, decreasing to 18.5 years for females and 23.7 years for males in 2019.

Despite the overall improvements, disparities in life expectancy persisted across all states within each race/ethnicity group.

Among females, for example, non-Hispanic Black females had the lowest mean life expectancy across states in 1990 (74.2 years) but had the greatest improvement on average (6.9% increase) by 2019. However, the mean LE for non-Hispanic Black females remained lower than it did for non-Hispanic White and Hispanic females.

Among males, the researchers found differences in life expectancies across states between the people of the three different ethnicities they studied. The greatest difference in life expectancies in 1990 was 24.5 years. This occurred between non-Hispanic Black males in the District of Columbia and Hispanic males in Georgia. The life expectancy for these non-Hispanic Black males was 59.4 years, versus 83.8 years for these Hispanic males that year.

This reduced life expectancy for non-Hispanic Black males persisted, although it improved slightly by 2019. That year, the largest race-based disparity – which was approximately 24 years – occurred between non-Hispanic Black males in the District of Columbia and Hispanic males in Virginia. For the Hispanic males in Virgina, the LE was 90.7 years versus 66.9 years for non-Hispanic Black males in the District of Columbia.

The findings were limited by several factors including the review of data from only 23 states, the focus on life expectancy from birth versus other ages, and the challenges of defining Hispanic ethnicity, the researchers noted. However, the results support that the potential use of state-level analysis that includes race/ethnicity could be a valuable tool for measuring health inequity as part of national average trends, they said.
 

Health has truly stagnated for some in certain states

“Subpopulations in some states have much longer life expectancy now than 30 years ago. But in some states, we were struck by how health has truly stagnated for some,” Dr. Roth said in an interview. “We were surprised by the scale of the overall gap; a difference of about 8 years between states is more than twice that if you drill down to race/ethnicity groups in each state.”

A key message from the study is the need for all clinicians to advocate for improved access to primary care, “which is increasingly hard to obtain for many people,” said Dr. Roth. “So much of health is determined by key risk factors such as high blood pressure, high cholesterol, obesity, diabetes, alcohol use, tobacco use. But many of the determinants of health are not in the healthcare system, and include efforts to improve education, interrupt cycles of poverty, and teach healthy behaviors at a very young age. “Racism remains a underdiscussed part of these disparities, and we need better ways to measure the impact of social policies that end up impacting health down the road,” he said.

Looking ahead: “There is a lot to be learned from the states that have improved life expectancy the most. We need researchers to work together to identify and communicate what are those best practices, and what state governments can do to play their part.”

State-level differences reveal variations in health care

“The findings add to our growing knowledge of large and persistent racial/ethnic health disparities and changes in disparities during recent stagnation in U.S. life expectancy,” wrote Hedwig Lee, PhD, of Washington University in St. Louis, and Kathleen M. Harris, PhD, of the University of North Carolina at Chapel Hill, in an accompanying editorial.

The focus on state-level differences provides a unique window into the huge variation in life expectancy by race/ethnicity across the United States. The data suggest that “a person’s life expectancy in the United States may depend more on where you live than it has in the past,” they noted. For example, the editorialists highlighted that life expectancy for non-Hispanic Black men in 2019 averaged 81.1 years in Rhode Island, but 66.9 years in the District of Columbia.

They also noted the study’s lack of data for many states with high mortality rates and high proportions of non-Hispanic Black persons, Hispanic persons, and those with low socioeconomic states. Including data from these areas may have yielded even greater disparities in life expectancy.

“Despite substantial declines in mortality among Black persons during the study period, a non-Hispanic Black person’s life expectancy remained persistently lower than that of non-Hispanic White and Hispanic persons, both within and across states,” the editorialists wrote. “Future research needs to unpack the complex web of factors driving health and well-being by enabling better understanding of the places where we see persistent health disadvantage and advantage and the state-based explanations for these increasingly important differences determining population risk and resilience. We should be outraged by disparities in longevity and called to act to eliminate them.”
 

Identifying the problem is the first step

“In order to address or fix a problem we should first identify and quantify the problem,” Noel Deep, MD, an internal medicine physician in private practice in Antigo, Wisc., said in an interview.

“This study provides us with the information regarding the trends in life expectancy within states and the disparities in life expectancy when race/ ethnicity and gender are factored into the equation,” said Dr. Deep, who was not involved in the study. “Based on previously available data, we are aware of the increase in life expectancy in the United States over the last few decades, as well as differences in life expectancy for the different ethnicities/races and genders, but these data provide averages, not state or geographical differences. By having this knowledge at a state level, we can use that data to make health policies that address those health inequities and allocate appropriate resources at a state or local level.”

Several studies have identified disparities in health care and life expectancy based on the zip codes, such as the U.S. Small-Area Life Expectancy Estimates Project in 2018. The current study “provides further information for health care professionals and policy makers about the disparities in health outcomes and life expectancy based on race as well as gender, and it is quite detailed,” he said. 

“As clinicians, we should strive to ensure that we are addressing these health inequities through our provision of clinical care and through our advocacy on behalf of our patients so that our nation’s health will improve overall,” he said.

“I would like to see future studies look at the socioeconomic status (income), urban versus rural residence, and place of birth (especially for immigrants),” said Dr. Deep. He also emphasized a need for studies to include the demographics for Hispanic populations; given the possible selection error “because of only healthy individuals immigrating to the United States or the older sicker Hispanics who might be migrating back to their homelands and not being included in the data and falsely increasing the life expectancy for this race/ ethnic groups.

“I would also like to see some research into the cultural and social factors that might explain why Hispanic populations might have a higher life expectancy even if their socioeconomic status is poor,” he said.

The study was supported by the National Heart, Lung, and Blood Institute. The researchers had no financial conflicts to disclose. The editorialists had no financial conflicts to disclose. Dr. Deep had no financial conflicts to disclose, but serves on the editorial advisory board of Internal Medicine News and as chair of the AMA’s Council on Science and Public Health.

Pregnancy termination for medical reasons had been part of the fabric of everyday health care in the United States since the Supreme Court’s 1973 Roe v. Wade decision, which the current high court overturned in a ruling announced on June 24.

That means many clinicians across specialties are entering uncharted territory with the country’s new patchwork of abortion legality. Some specialties, cardiology among them, may feel the impact more than others.

“Unfortunately,” Dr. Haythe said, “many of the states that are going to make or have made abortion illegal are not providing that kind of preconception counseling or good prenatal care to women.”

Cardiologists can provide such counseling to their female patients of childbearing age who have high-risk cardiac conditions, “but not everybody knows that they have a heart problem when they get pregnant, and not everybody is getting screened for heart problems when they’re of childbearing age,” Dr. Haythe said.

“Sometimes it’s not clear whether the problems could have been picked up until a woman is pregnant and has started to have symptoms.” For example, “a lot of women with poor access to health care have rheumatic heart disease. They may have no idea that they have severe aortic stenosis, and it’s not until their second trimester that they start to feel really short of breath.” Often that can be treated in the cath lab, “but again, that’s putting the woman and the baby at risk.”

Cardiologists in states where abortion is illegal will still present the option to their patients with high-risk pregnancies, noted Dr. Haythe. But the conversation may sound something like, “you are at very high risk, termination of the pregnancy takes that risk away, but you’ll have to find a state where it’s legal to do that.”

Dr. Park said such a situation, when abortion is recommended but locally unavailable, is much like any other in cardiology for which the patient may want a second opinion. If a center “doesn’t have the capability or the technology to offer a certain treatment, the patient can opt to seek another opinion at another center,” she said. “Patients will often travel out of state to get the care they need.”

A requirement for out-of-state travel to obtain abortions is likely to worsen socioeconomic disparities in health care, Dr. Bond observed, “because we know that those who are low-income won’t be able to afford that travel.”

Dr. Bond is cosignatory on a statement from the Association of Black Cardiologists (ABC) responding to the high court’s ruling in Dobbs v. Jackson. “This decision will isolate the poor, socioeconomically disadvantaged, and minority populations specifically, widening the already large gaps in health care for our most vulnerable communities,” it states.

“The loss of broad protections supporting the medical and often lifesaving procedure of abortions is likely to have a real impact on the maternal mortality rate, especially in those with congenital and/or acquired cardiovascular conditions where evidence-based guidelines advise at times on termination of such high-risk pregnancies.”

The ABC, it states, “believes that every woman, and every person, should be afforded the right to safe, accessible, legal, timely, patient-centered, equitable, and affordable health care.”

The American College of Cardiology (ACC) released a statement on the matter June 24, signed by its president, Edward T.A. Fry, MD, along with five former ACC presidents. “While the ACC has no official policy on abortion, clinical practice guidelines and other clinical guidance tools address the dangers of pregnancy in certain patient populations at higher risk of death or serious cardiac events.”

The college, it states, is “deeply concerned about the potential implications of the Supreme Court decision regarding Roe vs. Wade on the ability of patients and clinicians to engage in important shared discussions about maternal health, or to remove previously available health care options.”

Dr. Bond proposed that a “vocal stance” from medical societies involved in women’s health, “perhaps even a collective stance from our cardiovascular societies and our obstetrics societies,” would also perhaps reach “the masses of doctors in private practice who are dealing with these patients.”

Boys with obesity have lower testicular volume, compared with their normal-weight counterparts, suggesting the potential for fertility problems in adulthood, new data suggest.

Testicular volume is a fertility marker directly related to sperm count that has halved in the past 40 years worldwide for unknown reasons. At the same time, childhood obesity has risen dramatically and infertility appears to have risen as well, Rossella Cannarella, MD, of the department of endocrinology and andrology, University of Catania (Italy), said at the annual meeting of the Endocrine Society.

According to recent Italian studies, between 14% and 23% of young men aged 18-19 had testicular hypotrophy. “Worryingly, we don’t know the reason for this hypotrophy. And therefore, they are at risk for future infertility,” Dr. Cannarella said during a press briefing.

Her study, which included a total of 264 male children and adolescents, also linked lower testicular volume to hyperinsulinemia and insulin resistance. “The testis is not quiescent in childhood and is sensitive to the hormone insulin. Obesity and metabolic impairment actually can have an effect and negative impact on Sertoli cell proliferation,” Dr. Cannarella said.
 

Screen testicular volume at all visits

If other studies confirm these results, she said that pediatricians should begin routinely assessing testicular volume at all visits as is now done with height and weight to identify early deflection of the testicular growth curve.

In addition, “include male infertility as a possible consequence of obesity in counseling of male obese children,” she advised.

Asked to comment, Amin Sedaghat Herati, MD, director of male infertility and men’s health at Johns Hopkins Hospital, and assistant professor of urology at Johns Hopkins Medicine, both in Baltimore, said in an interview: “I think what’s really interesting about this study is the association that they’ve made between testicular volume and obesity.”

But, he noted, “it does not implicate necessarily the development of infertility. It’s an extrapolation. So it’s a step towards the link between obesity and infertility, and it’s an important study to establish the association, but changes in testicular volume and even changes in semen panel don’t necessarily indicate fertility or infertility.”

The findings are “consistent with what we know as far as what obesity can potentially do to the activity of the cells in the testes. The authors are postulating that it’s more the support cells, called Sertoli cells, but I would say it’s probably all of the cells that are being affected by obesity and specifically elevated leptin levels,” Dr. Herati said.

He agrees with the recommendation that pediatricians screen all boys for testicular volume. “I agree it’s a good idea so they don’t miss any cases in which the testes don’t develop the way they should or any other conditions,” Dr. Herati said. “I think in general it’s a good practice, especially in the peripubertal stage, to make sure that kids are on the same growth curve and that they’re meeting their Tanner staging. [Pediatricians] should be looking at the size of the testes and tracking, maybe not at every visit, but at least on an annual basis.”

And, he noted, “I think any study that establishes a link that we can point to when we’re educating patients and parents is important.”
 

Links found between overweight/obesity, testicular hypotrophy

The study population included 61 male children and adolescents with normal weight, 53 with overweight, and 150 with obesity. Insulin resistance (Homeostatic Model Assessment for Insulin Resistance index ≥ 2.5) was present in 97 participants, 22 had prediabetes, and 3 had type 2 diabetes. Clinical data were collected retrospectively.

Among the boys aged 9-14 years, those with overweight and obesity had significantly lower testicular volume, compared with those of normal weight.

Those who were in Tanner Stage 1 were more likely to have overweight and obesity than those with normal weight, suggesting that “overweight and obese adolescents start puberty later than those of normal weight,” Dr. Cannarella said.

In the 14- to 16-year-old age group, those with insulin resistance had lower testicular volume, compared with those without insulin resistance (HOMA index < 2.5). The number of insulin-resistant adolescents was greater than that of controls in the Tanner stage 2 group.

In both the prepubertal (< 9 years) and pubertal (14-16 years) groups, hyperinsulinemia was associated with lower levels of testicular volume.

Hyperinsulinemia did not influence the timing of puberty onset.
 

No way to quantify the effect of obesity on fertility just yet

During a press briefing, Dr. Cannarella commented that obesity is likely just one of several factors influencing what appears to be an increase in male infertility over time. “It isn’t of course the only reason, but many factors in our environment have drastically changed, compared to 40 years ago, including the prevalence of heavy metals and endocrine disruptors, and of course, the change in habits and higher prevalence of metabolic disease. All of this has an impact on the proliferation of Sertoli cells in childhood and this may explain the trend toward the decline of sperm concentration and count.”

Longitudinal data are needed to establish cause and effect, she noted. “We need longitudinal studies that link the degrees of testicular volume with the degree of the sperm concentration and count starting from childhood and ending with the adult age. This is the missing link so far.”

Dr. Cannarella has reported no relevant financial relationships. Dr. Herati has reported being an advisor for Dadi, LiNA Medical, and Teleflex.

LONDON – Around the world, nonalcoholic fatty liver disease (NAFLD) has driven an increase in deaths from liver cancer over the past decade, overtaking alcoholic liver disease, hepatitis B, and hepatitis C, according to an analysis of the Global Burden of Disease Study 2019.

A global rise in liver cancer deaths and chronic liver disease reflects changes in underlying health patterns, said Zobair Younossi, MD, MPH, professor and chair, department of medicine, Inova Fairfax Medical Campus, Falls Church, Va., who presented the analysis at the meeting sponsored by the European Association for the Study of the Liver.

“NAFLD and NASH [nonalcoholic steatohepatitis] are rapidly becoming the main causes of cirrhosis and liver cancer in the world,” Dr. Younossi told this news organization. “We have known about the increasing prevalence for some time, but now the outcomes in terms of mortality are catching up,” he said.

“The bottom line of this study is that the burden of this disease [NAFLD] is going up, and it will be the most important disease of the next decade or so,” he said, adding that “the largest annual percentage increase in rates of mortality from liver cancer or chronic liver disease cirrhosis is related to NAFLD.”

Specifically, during the decade of 2009–2019, the annual percent change of +1.33% in the global liver cancer death rate was driven by the fact that the APC for NAFLD was +2.47%. By comparison, the APC for alcoholic liver disease was +1.91%; for hepatitis B, the APC was +0.21%; and for hepatitis C, the APC was +1.12%.

Aleksander Krag, MD, PhD, professor and senior consultant of hepatology and director of Odense (Denmark) Liver Research Centre at SDU and Odense University Hospital, who chaired the session in which this presentation was a part, acknowledged the importance of recognizing the contribution of NAFLD to liver cancer mortality.

“Liver diseases are on the rise. They are the fastest rising cause of death in the United Kingdom, faster than heart disease and other cancers. NAFLD in particular is the fastest growing cause of liver cancer, and the leading cause in France and the United States,” he remarked.

Dr. Krag also highlighted the costs of disease management.

“Managing fatty liver disease in Europe is estimated at €35 billion in direct health care, so we need to do something now,” he stressed.

“The global burden of NAFLD is so high that we need both prevention and treatment tools,” Dr. Krag said. “Change to lifestyle is a ‘no-brainer’ and costs governments very little. For the sake of our young people, we need to take this very seriously. At a political level, we can easily implement this, for example, by banning junk food advertisements, but also educating young people and their families. Good drugs will also help.”
 

NAFLD: The liver manifestation of type 2 diabetes

About 25%-30% of the global population have NAFLD, and 3%-5% have NASH. Dr. Younossi highlighted that the U.S. transplant database shows that NAFLD was the second indication for all liver transplants in the country. NAFLD also was a leading cause of liver transplants for patients with hepatocellular carcinoma.

There are around 2 billion cases of chronic liver disease globally, he said. He noted that, over time, there has been an increase in all kinds of liver diseases, as reflected in the annual percent change.

“The global epidemic of obesity and type 2 diabetes is driving the rise in NAFLD, but even among lean people, the prevalence of NAFLD is around 9%,” Dr. Younossi said. “Alongside the eye and kidney complications of diabetes, this is the liver manifestation of type 2 diabetes.”

To assess global liver disease and death, Dr. Younossi and his colleagues turned to the Global Burden of Disease Study, which gathered data from around 7,000 investigators located across 22 different regions of the world, comprising 156 countries.

They calculated the incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) in relation to liver cancer and chronic liver disease, including the APC. They linked the data to changes in four liver diseases: NAFLD, alcoholic liver disease, hepatitis B infection, and hepatitis C infection.

The cases of NAFLD reported in the study had been diagnosed by ultrasound or other imaging. Importantly, the prevalence of NAFLD was adjusted for alcohol use in the various national populations, explained Dr. Younossi.

In 2019, they reported that the overall global prevalence of liver disease reached 1.69 billion (liver cancer, 0.04%; chronic liver disease, 99.96%), with an incidence of 2.59 million (liver cancer, 20.7%; chronic liver disease, 79.3%), mortality of 1.95 million (liver cancer, 24.8%; chronic liver disease, 75.3%), and DALYs of 58.7 million (liver cancer, 21.3%; chronic liver disease, 78.7%).

Between 2009 and 2019, deaths from liver cancer rose by 27.2%, and deaths from chronic liver disease rose by 10.6%. DALYs from liver cancer rose by 21.9%, and DALYs from chronic liver disease were up by 5.1%.

In contrast to the increase in liver cancer deaths, deaths from chronic liver disease decreased (APC, –0.18%). The decrease was driven by a decrease in hepatitis B (APC, –1.83%). APCs for hepatitis C (+0.37%), alcoholic liver disease (+0.45%), and NAFLD (+1.33%) increased.

“The burden of hepatitis B–related mortality has decreased because we have been so good at vaccinating people,” Dr. Younossi remarked.
 

NAFLD ‘exploding’ in Middle East, North Africa, and East Asia

The increase in NAFLD has been seen in all regions of the world, but a breakdown by region shows that NAFLD is primarily “exploding” with highest prevalence and mortality in the Middle East (mostly Egypt, Iran, and Turkey), North Africa, and East Asia, said Dr. Younossi. In addition, there are large increases in the West and South America.

“We knew that the prevalence was high in the Middle East, but we now know that mortality is also high, so we are connecting these data,” said Dr. Younossi.
 

Awareness lacking

Dr. Younossi pressed the fact that awareness among the general population, primary care providers, and policy makers is very low. “From my perspective, raising awareness of NAFLD is the No. 1 priority, and that is the value of this study.”

He added that more people will become aware as testing becomes more manageable.

“There are some noninvasive tests being developed, so in the future, we won’t have to do liver biopsies to diagnose these patients,” he said. “Currently, there are some excellent treatments being developed.”

“The [World Health Organization] does not mention NAFLD as an important noncommunicable disease, and this too has to change,” Dr. Younossi added.

Dr. Younossi has received research funds and/or has consulted for Abbott, Allergan, Bristol-Myers Squibb, Echosens, Genfit, Gilead Sciences, Intercept, Madrigal, Merck, and Novo Nordisk. Dr. Karg disclosed no relevant financial relationships.

LONDON – Around the world, nonalcoholic fatty liver disease (NAFLD) has driven an increase in deaths from liver cancer over the past decade, overtaking alcoholic liver disease, hepatitis B, and hepatitis C, according to an analysis of the Global Burden of Disease Study 2019.

A global rise in liver cancer deaths and chronic liver disease reflects changes in underlying health patterns, said Zobair Younossi, MD, MPH, professor and chair, department of medicine, Inova Fairfax Medical Campus, Falls Church, Va., who presented the analysis at the meeting sponsored by the European Association for the Study of the Liver.

“NAFLD and NASH [nonalcoholic steatohepatitis] are rapidly becoming the main causes of cirrhosis and liver cancer in the world,” Dr. Younossi told this news organization. “We have known about the increasing prevalence for some time, but now the outcomes in terms of mortality are catching up,” he said.

“The bottom line of this study is that the burden of this disease [NAFLD] is going up, and it will be the most important disease of the next decade or so,” he said, adding that “the largest annual percentage increase in rates of mortality from liver cancer or chronic liver disease cirrhosis is related to NAFLD.”

Specifically, during the decade of 2009–2019, the annual percent change of +1.33% in the global liver cancer death rate was driven by the fact that the APC for NAFLD was +2.47%. By comparison, the APC for alcoholic liver disease was +1.91%; for hepatitis B, the APC was +0.21%; and for hepatitis C, the APC was +1.12%.

Aleksander Krag, MD, PhD, professor and senior consultant of hepatology and director of Odense (Denmark) Liver Research Centre at SDU and Odense University Hospital, who chaired the session in which this presentation was a part, acknowledged the importance of recognizing the contribution of NAFLD to liver cancer mortality.

“Liver diseases are on the rise. They are the fastest rising cause of death in the United Kingdom, faster than heart disease and other cancers. NAFLD in particular is the fastest growing cause of liver cancer, and the leading cause in France and the United States,” he remarked.

Dr. Krag also highlighted the costs of disease management.

“Managing fatty liver disease in Europe is estimated at €35 billion in direct health care, so we need to do something now,” he stressed.

“The global burden of NAFLD is so high that we need both prevention and treatment tools,” Dr. Krag said. “Change to lifestyle is a ‘no-brainer’ and costs governments very little. For the sake of our young people, we need to take this very seriously. At a political level, we can easily implement this, for example, by banning junk food advertisements, but also educating young people and their families. Good drugs will also help.”
 

NAFLD: The liver manifestation of type 2 diabetes

About 25%-30% of the global population have NAFLD, and 3%-5% have NASH. Dr. Younossi highlighted that the U.S. transplant database shows that NAFLD was the second indication for all liver transplants in the country. NAFLD also was a leading cause of liver transplants for patients with hepatocellular carcinoma.

There are around 2 billion cases of chronic liver disease globally, he said. He noted that, over time, there has been an increase in all kinds of liver diseases, as reflected in the annual percent change.

“The global epidemic of obesity and type 2 diabetes is driving the rise in NAFLD, but even among lean people, the prevalence of NAFLD is around 9%,” Dr. Younossi said. “Alongside the eye and kidney complications of diabetes, this is the liver manifestation of type 2 diabetes.”

To assess global liver disease and death, Dr. Younossi and his colleagues turned to the Global Burden of Disease Study, which gathered data from around 7,000 investigators located across 22 different regions of the world, comprising 156 countries.

They calculated the incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) in relation to liver cancer and chronic liver disease, including the APC. They linked the data to changes in four liver diseases: NAFLD, alcoholic liver disease, hepatitis B infection, and hepatitis C infection.

The cases of NAFLD reported in the study had been diagnosed by ultrasound or other imaging. Importantly, the prevalence of NAFLD was adjusted for alcohol use in the various national populations, explained Dr. Younossi.

On the 50th anniversary of Title IX’s inception, the Biden administration has proposed changes to the law that would protect transgender students and assault survivors on college and university campuses.

With these changes, the protections provided by Title IX – a civil rights law that prohibits sex-based discrimination in schools that receive federal funding – would now be extended to students who identify as trans. The update would ensure that government-funded schools make proper accommodations for a trans student population, such as allowing students to use bathrooms and other facilities that align with their gender identity, and enforcing the use of students’ correct pronouns.

The revisions also seek to undo amendments made to the law by Betsy DeVos, who was secretary of education during the Trump presidency, which strengthened due process protections for students accused of sexual assault and narrowed the definition of sexual harassment. These rules “weakened protections for survivors of sexual assault and diminished the promise of an education free from discrimination,” the Biden administration said.

“Our proposed changes will allow us to continue that progress and ensure all our nation’s students – no matter where they live, who they are, or whom they love – can learn, grow, and thrive in school,” Education Secretary Miguel Cardona, PhD, said in a news release. “We welcome public comment on these critical regulations so we can further the Biden-Harris Administration’s mission of creating educational environments free from sex discrimination and sexual violence.”

The revisions will go through a long period of public comment before they are set into law. Still, the proposed changes mark a way forward for trans students who are not explicitly protected under Title IX, and they offer solace to assault survivors who may have felt discouraged to come forward and report under Ms. DeVos’s rules.

“The proposed regulations reflect the [Education] Department’s commitment to give full effect to Title IX, ensuring that no person experiences sex discrimination in education, and that school procedures for addressing complaints of sex discrimination, including sexual violence and other forms of sex-based harassment, are clear, effective, and fair to all involved,” said Catherine Lhamon, JD, assistant secretary for the Education Department’s Office Of Civil Rights.

More specific rules about transgender students’ participation in school sports are still to come.

Infertility, pregnancy loss, and stillbirth increased women’s later risk of both nonfatal and fatal stroke, based on data from more than 600,000 women.

“To date, multiple studies have generated an expanding body of evidence on the association between pregnancy complications (e.g., gestational diabetes and preeclampsia) and the long-term risk of stroke, but studies on associations with infertility, miscarriage, or stillbirth have produced mixed evidence,” Chen Liang, a PhD candidate at the University of Queensland, Brisbane, Australia, and colleagues wrote.

In a study published in the BMJ, the researchers reviewed data from eight observational cohort studies across seven countries (Australia, China, Japan, the Netherlands, Sweden, the United Kingdom, and the United States). The participants were part of the InterLACE (International Collaboration for a Life Course Approach to Reproductive Health and Chronic Disease Events) consortium established in 2021. Most observational studies included in the analysis began between 1990 and 2000.

The study population included 618,851 women aged 32-73 years at baseline for whom data on infertility, miscarriage, or stillbirth, were available. The primary outcome was the association of infertility, recurrent miscarriage, and stillbirth with risk of first fatal or nonfatal stroke, and the results were further stratified by subtype. Stroke was identified through self-reports, linked hospital data, national patient registers, or death registry data. Baseline was defined as the first incidence of infertility, miscarriage, or stillbirth. The exception was the National Survey of Health and Development, a British birth cohort started in 1946, that collected data retrospectively.

The median follow-up period was 13 years for nonfatal stroke and 9.4 years for fatal stroke.

Overall, 17.2%, 16.6%, and 4.6% of the women experienced infertility, miscarriage, and stillbirth, respectively.

Women with a history of infertility had a significantly higher nonfatal stroke risk, compared with those without infertility (hazard ratio, 1.14). Further analysis by stroke subtypes showed an increased association between miscarriage and ischemic stroke (HR, 1.15).

Those with a history of miscarriage also had an increased risk of nonfatal stroke, compared with those without miscarriages (HR, 1.11). In the miscarriage group, the risk of stroke increased with the number of miscarriages, with adjusted HRs of 1.07, 1.12, and 1.35 for women with one, two, and three or more miscarriages, respectively. When stratified by stroke subtype, women with three or more miscarriages were more likely than women with no miscarriages to experience ischemic and hemorrhagic nonfatal strokes.

Associations were similar between miscarriage history and fatal stroke risk. Women with one, two, and three or more miscarriages had increased risk of fatal stroke, compared with those with no miscarriages (aHR, 1.08, 1.26, and 1.82, respectively, and women with three or more miscarriages had a higher risk of ischemic and hemorrhagic stroke (aHR, 1.83 and 1.84, respectively).

Women with a history of stillbirth had an approximately 31% increased risk of nonfatal stroke, compared with those with no history of stillbirth, with aHRs similar for single and recurrent stillbirths (1.32 and 1.29, respectively). Ischemic nonfatal stroke risk was higher in women with any stillbirth, compared with those without stillbirth (aHR, 1.77). Fatal stroke risk also was higher in women with any stillbirth, compared with those without, and this risk increased with the number of stillbirths (HR, 0.97 and HR, 1.26 for those with one stillbirth and two or more, respectively).

“The increased risk of stroke associated with infertility or recurrent stillbirths was mainly driven by a single subtype of stroke (nonfatal ischemic stroke or fatal hemorrhagic stroke, respectively), whereas the risk of stroke associated with recurrent miscarriages was driven by both subtypes,” the researchers wrote.

The researchers cited endothelial dysfunction as a potential underlying mechanism for increased stroke risk associated with pregnancy complications. “Endothelial dysfunction might lead to pregnancy loss through placentation-related defects, persist after a complicated pregnancy, and contribute to the development of stroke through reduced vasodilation, proinflammatory status, and prothrombic properties,” and that history of recurrent pregnancy loss might be a female-specific risk factor for stroke.

To mitigate this risk, they advised early monitoring of women with a history of recurrent miscarriages and stillbirths for stroke risk factors such as high blood pressure, blood sugar levels, and lipid levels.

The study findings were limited by several factors including the use of questionnaires to collect information on infertility, miscarriage, and stillbirth, and the potential variation in definitions of infertility, miscarriage, and stillbirth across the included studies, and a lack of data on the effect of different causes or treatments based on reproductive histories, the researchers noted. Other limitations include incomplete data on stroke subtypes and inability to adjust for all covariates such as thyroid disorders and endometriosis. However, the results were strengthened by the large study size and geographically and racially diverse population, extend the current knowledge on associations between infertility, miscarriage, and stillbirth with stroke, and highlight the need for more research on underlying mechanisms.
 

Data support gender-specific stroke risk stratification

“Studies that seek to understand gender differences and disparities in adverse outcomes, such as stroke risk, are extremely important given that women historically were excluded from research studies,” Catherine M. Albright, MD, of the University of Washington, Seattle, said in an interview. “By doing these studies, we are able to better risk stratify people in order to better predict and modify risks,” added Dr. Albright, who was not involved in the current study.

“It is well known than adverse pregnancy outcomes such as hypertension in pregnancy, fetal growth restriction, and preterm birth, lead to increased risk of cardiovascular disease and stroke later in life, so the general findings of an association between other adverse reproductive and pregnancy outcomes leads to increased stroke risk are not surprising,” she said.

“The take-home message is that outcomes for pregnancy really do provide a window to future health,” said Dr. Albright. “For clinicians, especially non-ob.gyns., knowing a complete pregnancy history for any new patient is important and can help risk-stratify patients, especially as we continue to gain knowledge like what is shown in this study.”

However, “this study did not evaluate why individual patients may have had infertility, recurrent pregnancy loss, or stillbirth, so research to look further into this association to determine if there is an underlying medical condition that could be treated and therefore possibly reduce both pregnancy complications and future stroke risks would be important,” Dr. Albright noted.

The study was supported by the Australian National Health and Medical Research Council Centres of Research Excellence; one corresponding author was supported by an Australian National Health and Medical Research Council Investigator grant. The researchers had no financial conflicts to disclose. Dr. Albright had no financial conflicts to disclose.

Infertility, pregnancy loss, and stillbirth increased women’s later risk of both nonfatal and fatal stroke, based on data from more than 600,000 women.

The researchers cited endothelial dysfunction as a potential underlying mechanism for increased stroke risk associated with pregnancy complications. “Endothelial dysfunction might lead to pregnancy loss through placentation-related defects, persist after a complicated pregnancy, and contribute to the development of stroke through reduced vasodilation, proinflammatory status, and prothrombic properties,” and that history of recurrent pregnancy loss might be a female-specific risk factor for stroke.

To mitigate this risk, they advised early monitoring of women with a history of recurrent miscarriages and stillbirths for stroke risk factors such as high blood pressure, blood sugar levels, and lipid levels.

The study findings were limited by several factors including the use of questionnaires to collect information on infertility, miscarriage, and stillbirth, and the potential variation in definitions of infertility, miscarriage, and stillbirth across the included studies, and a lack of data on the effect of different causes or treatments based on reproductive histories, the researchers noted. Other limitations include incomplete data on stroke subtypes and inability to adjust for all covariates such as thyroid disorders and endometriosis. However, the results were strengthened by the large study size and geographically and racially diverse population, extend the current knowledge on associations between infertility, miscarriage, and stillbirth with stroke, and highlight the need for more research on underlying mechanisms.
 

Data support gender-specific stroke risk stratification

“Studies that seek to understand gender differences and disparities in adverse outcomes, such as stroke risk, are extremely important given that women historically were excluded from research studies,” Catherine M. Albright, MD, of the University of Washington, Seattle, said in an interview. “By doing these studies, we are able to better risk stratify people in order to better predict and modify risks,” added Dr. Albright, who was not involved in the current study.

“It is well known than adverse pregnancy outcomes such as hypertension in pregnancy, fetal growth restriction, and preterm birth, lead to increased risk of cardiovascular disease and stroke later in life, so the general findings of an association between other adverse reproductive and pregnancy outcomes leads to increased stroke risk are not surprising,” she said.

“The take-home message is that outcomes for pregnancy really do provide a window to future health,” said Dr. Albright. “For clinicians, especially non-ob.gyns., knowing a complete pregnancy history for any new patient is important and can help risk-stratify patients, especially as we continue to gain knowledge like what is shown in this study.”

However, “this study did not evaluate why individual patients may have had infertility, recurrent pregnancy loss, or stillbirth, so research to look further into this association to determine if there is an underlying medical condition that could be treated and therefore possibly reduce both pregnancy complications and future stroke risks would be important,” Dr. Albright noted.

The researchers had no financial conflicts to disclose. Dr. Albright had no financial conflicts to disclose.

Infertility, pregnancy loss, and stillbirth increased women’s later risk of both nonfatal and fatal stroke, based on data from more than 600,000 women.

“To date, multiple studies have generated an expanding body of evidence on the association between pregnancy complications (e.g., gestational diabetes and preeclampsia) and the long-term risk of stroke, but studies on associations with infertility, miscarriage, or stillbirth have produced mixed evidence,” Chen Liang, a PhD candidate at the University of Queensland, Brisbane, Australia, and colleagues wrote.

In a study published in the BMJ, the researchers reviewed data from eight observational cohort studies across seven countries (Australia, China, Japan, the Netherlands, Sweden, the United Kingdom, and the United States). The participants were part of the InterLACE (International Collaboration for a Life Course Approach to Reproductive Health and Chronic Disease Events) consortium established in 2021. Most observational studies included in the analysis began between 1990 and 2000.

The study population included 618,851 women aged 32-73 years at baseline for whom data on infertility, miscarriage, or stillbirth, were available. The primary outcome was the association of infertility, recurrent miscarriage, and stillbirth with risk of first fatal or nonfatal stroke, and the results were further stratified by subtype. Stroke was identified through self-reports, linked hospital data, national patient registers, or death registry data. Baseline was defined as the first incidence of infertility, miscarriage, or stillbirth. The exception was the National Survey of Health and Development, a British birth cohort started in 1946, that collected data retrospectively.

The median follow-up period was 13 years for nonfatal stroke and 9.4 years for fatal stroke.

Overall, 17.2%, 16.6%, and 4.6% of the women experienced infertility, miscarriage, and stillbirth, respectively.

Women with a history of infertility had a significantly higher nonfatal stroke risk, compared with those without infertility (hazard ratio, 1.14). Further analysis by stroke subtypes showed an increased association between miscarriage and ischemic stroke (HR, 1.15).

Those with a history of miscarriage also had an increased risk of nonfatal stroke, compared with those without miscarriages (HR, 1.11). In the miscarriage group, the risk of stroke increased with the number of miscarriages, with adjusted HRs of 1.07, 1.12, and 1.35 for women with one, two, and three or more miscarriages, respectively. When stratified by stroke subtype, women with three or more miscarriages were more likely than women with no miscarriages to experience ischemic and hemorrhagic nonfatal strokes.

Associations were similar between miscarriage history and fatal stroke risk. Women with one, two, and three or more miscarriages had increased risk of fatal stroke, compared with those with no miscarriages (aHR, 1.08, 1.26, and 1.82, respectively, and women with three or more miscarriages had a higher risk of ischemic and hemorrhagic stroke (aHR, 1.83 and 1.84, respectively).

Women with a history of stillbirth had an approximately 31% increased risk of nonfatal stroke, compared with those with no history of stillbirth, with aHRs similar for single and recurrent stillbirths (1.32 and 1.29, respectively). Ischemic nonfatal stroke risk was higher in women with any stillbirth, compared with those without stillbirth (aHR, 1.77). Fatal stroke risk also was higher in women with any stillbirth, compared with those without, and this risk increased with the number of stillbirths (HR, 0.97 and HR, 1.26 for those with one stillbirth and two or more, respectively).

Infants who were introduced to a low-protein diet – high in fruit, vegetables, and roots – ate more fruits and vegetables at 12 and 18 months of age, compared with those who ate a conventional diet, in a new study.

The “Nordic diet” has shown health benefits in children and adults, but has not been studied in infants, said Ulrica Johansson, MD, of Umeå (Sweden) University, in a presentation on the study at the annual meeting of the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition.

A healthy and sustainable diet early in life could have a significant impact on future health, Dr. Johansson said in an interview.

Dr. Johansson and colleagues aimed to investigate the effect of a Nordic diet in infants aged 4-18 months in the OTIS trial. All infants were breastfed or formula-fed at baseline.
 

Study methods and results

A total of 250 infants aged 4-6 months were randomized to consuming a Nordic diet or a conventional diet. Those in the Nordic group received exposures to Nordic foods and flavors, including Nordic fruit, berries, vegetables, and roots. Those in the conventional group received baby food products that followed the current Swedish dietary recommendations for infants. The researchers collected data on dietary intake, biomarkers, and growth from baseline up to 18 months of age.

Notably, acceptance of all the flavors in the Nordic diet was high, including those with sour or bitter taste, such as cranberry and white radish, Dr. Johansson said in her presentation. Food refusals were few, and did not differ among the Nordic food offerings.

At both 12- and 18-month follow-ups, infants in the Nordic group consumed 42%-45% more fruits and vegetables compared with those in the conventional group (P < .001). Plasma folate levels also were significantly higher in the Nordic group compared with in the conventional group, at both 12 months and 18 months (P < .001 and P < .003, respectively).

The daily mean protein intake ranged from 17% to 29% lower in the Nordic group compared with in the conventional group, at both 12 months and 18 months. The intake of protein in terms of g/kg of body weight was significantly lower in the Nordic group, at both time points. Lower protein intake was confirmed by blood urea nitrogen measurements.

The protein intake in the Nordic group still fell within the safe level recommended for healthy growth in young children by the World Health Organization, noted Dr. Johansson, and no significant differences were observed in growth between the groups. Total energy intake, iron status, and duration of breastfeeding also remained similar between the groups throughout the study period.

Parents received support from research nurses via social media and monthly clinic visits, which she believes contributed to the success of the intervention, she said.
 

Nordic diet offers feasible encouragement of healthy eating

The key message for clinicians, and for parents of young children, is that “the protein-reduced, Nordic diet is both feasible and safe for infants’ growth, nutritional requirements, and development during the complementary feeding period,” Dr. Johansson said in an interview. “Thus, it may serve as a healthy and environmentally sustainable diet alternative for infants and their parents in the future.”

“Nordic foods are feasible to use when exposing infants to a variety of flavors so that healthy food preferences can be established early in life; Nordic berries and some root vegetables are preferable when introducing bitter and sour tastes during the sensitive period,” she added.

“Multicomponent interventions with long-term follow-up are required to advance the field of child nutrition research,” Dr. Johansson emphasized. Home-based interventions are lacking, and “more studies are needed to bridge the gap in research between the transfer period from baby food to family food at 1-2 years of age.”

Large, randomized controlled studies of Nordic diet during infancy and later childhood are needed as well, said Dr. Johansson. “The long-term effects of the Nordic diet during this highly dynamic period of childhood need continued follow-up to school age to give indications of any lasting health effects,” and the researchers plan to follow the current study population at 7 years of age.

Findings reinforce need for better nutrition

Previous research documents concern for childhood obesity associated with higher intake of protein, fats and overall calories in infancy, said Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., in an interview. “The inclusion of high-calorie, high-fat foods contributes to obesity in all children, so focusing on intake of fruits and vegetables is extremely important early in life,” she said.

A key barrier to the widespread use of a Nordic-type diet is that and vegetables tend to be more expensive than other foods and may not be readily available to all families, especially lower income families, Dr. Haut added.

However, for primary care clinicians, the current study reinforces the need to encourage the intake of fruits and vegetables at all ages, beginning in infancy, she said.

Looking ahead, “there is still limited information in the literature about the ideal recommended daily protein, except for increased amounts needed for preterm infants, early infancy, and during periods of healing,” Dr. Haut emphasized. “Some controls for this study were not included in the abstract, such as monitoring what foods were given to the infants in the conventional group. Parent and caregiver interpretation of recommendations can be highly variable,” she noted. Also, “The activity levels of late infancy and toddlers can vary in terms of energy usage, especially when crawling, walking, running and other exercise-related activities begin. These factors were not readily available in the abstract/study,” she said.
