Sustained Benefits With TransCon PTH in Hypoparathyroidism
TOPLINE:
Long-term treatment with TransCon parathyroid hormone (PTH), a replacement therapy for hypoparathyroidism, demonstrates sustained efficacy and safety in patients with hypoparathyroidism over 52 weeks, with 95% of participants able to discontinue conventional therapy.
METHODOLOGY:
- Conventional therapy for hypoparathyroidism (active vitamin D and elemental calcium) alleviates symptoms of hypocalcemia, but it does not improve insufficient PTH levels and is linked to long-term complications, such as nephrocalcinosis, nephrolithiasis, and renal dysfunction.
- This phase 3 (PaTHway) trial aimed to investigate the long-term efficacy, safety, and tolerability of TransCon PTH (palopegteriparatide) in adults with hypoparathyroidism.
- Overall, 82 patients with chronic hypoparathyroidism (mean age, 48.6 years; 78% women; 93% White) were randomly assigned to receive TransCon PTH or placebo, both coadministered with conventional therapy for 26 weeks.
- At the 26-week visit, patients who completed the blinded treatment (n = 79) were assigned to receive only TransCon PTH with conventional therapy in an ongoing 156-week open-label extension.
- For this analysis at week 52, the main efficacy endpoint was the proportion of patients (n = 78) with normal serum calcium levels (8.3-10.6 mg/dL) and independence from conventional therapy (active vitamin D and therapeutic doses of calcium); safety assessments included serum chemistries, 24-hour urine calcium excretion, and treatment-emergent adverse events.
TAKEAWAY:
- At week 52, the majority of the patients receiving TransCon PTH achieved normal serum calcium levels within the normal range (86%) and independence from conventional therapy (95%). None required active vitamin D.
- In secondary endpoints, patients receiving TransCon PTH showed sustained improvement in Hypoparathyroidism Patient Experience Scale scores, reflecting better symptom management, enhanced functioning, and overall well-being through week 52.
- At week 52, the mean 24-hour urine calcium excretion in patients first randomized to TransCon PTH was 185.1 mg/d, remaining well below the upper limit of normal (≤ 250 mg/d), while the placebo group mean fell to 223.1 mg/d during the open-label extension of TransCon PTH.
- TransCon PTH was well-tolerated, with most treatment-emergent adverse events being mild or moderate and none leading to treatment discontinuation.
IN PRACTICE:
“These results suggest that TransCon PTH may improve outcomes and advance the standard of care for adults living with hypoparathyroidism,” the authors wrote.
SOURCE:
The study was led by Bart L. Clarke, MD, Mayo Clinic, Rochester, Minnesota. It was published online in The Journal of Clinical Endocrinology & Metabolism.
LIMITATIONS:
The study’s limitations included the open-label design during the extension period, which may have introduced bias in patient-reported outcomes. Additionally, the study population was predominantly women and White, which may have limited the generalizability of the findings. Further research is needed to assess the long-term effects of TransCon PTH on renal complications. One patient died of fatal cardiac arrest deemed unrelated to the study drug.

A New and Early Predictor of Dementia?
, in new findings that may provide a potential opportunity to identify high-risk populations for targeted enrollment in clinical trials of dementia prevention and treatment.
Results of an international study assessing frailty trajectories showed frailty levels notably increased in the 4-9 years before dementia diagnosis. Even among study participants whose baseline frailty measurement was taken prior to that acceleration period, frailty was still positively associated with dementia risk, the investigators noted.
“We found that with every four to five additional health problems, there is on average a 40% higher risk of developing dementia, while the risk is lower for people who are more physically fit,” said study investigator David Ward, PhD, of the Centre for Health Services Research, The University of Queensland, Brisbane, Australia.
The findings were published online in JAMA Neurology.
A Promising Biomarker
An accessible biomarker for both biologic age and dementia risk is essential for advancing dementia prevention and treatment strategies, the investigators noted, adding that growing evidence suggests frailty may be a promising candidate for this role.
To learn more about the association between frailty and dementia, Ward and his team analyzed data on 29,849 participants aged 60 years or above (mean age, 71.6 years; 62% women) who participated in four cohort studies: the English Longitudinal Study of Ageing (ELSA; n = 6771), the Health and Retirement Study (HRS; n = 9045), the Rush Memory and Aging Project (MAP; n = 1451), and the National Alzheimer’s Coordinating Center (NACC; n = 12,582).
The primary outcome was all-cause dementia. Depending on the cohort, dementia diagnoses were determined through cognitive testing, self- or family report of physician diagnosis, or a diagnosis by the study physician. Participants were excluded if they had cognitive impairment at baseline.
Investigators retrospectively determined frailty index scores by gathering information on health and functional outcomes for participants from each cohort. Only participants with frailty data on at least 30 deficits were included.
Commonly included deficits included high blood pressure, cancer, and chronic pain, as well as functional problems such as hearing impairment, difficulty with mobility, and challenges managing finances.
Investigators conducted follow-up visits with participants until they developed dementia or until the study ended, with follow-up periods varying across cohorts.
After adjustment for potential confounders, frailty scores were modeled using backward time scales.
Among participants who developed incident dementia (n = 3154), covariate-adjusted expected frailty index scores were, on average, higher in women than in men by 18.5% in ELSA, 20.9% in HRS, and 16.2% in MAP. There were no differences in frailty scores between sexes in the NACC cohort.
When measured on a timeline, as compared with those who didn’t develop dementia, frailty scores were significantly and consistently higher in the dementia groups 8-20 before dementia onset (20 years in HRS; 13 in MAP; 12 in ELSA; 8 in NACC).
Increases in the rates of frailty index scores began accelerating 4-9 years before dementia onset for the various cohorts, investigators noted.
In all four cohorts, each 0.1 increase in frailty scores was positively associated with increased dementia risk.
Adjusted hazard ratios [aHRs] ranged from 1.18 in the HRS cohort to 1.73 in the NACC cohort, which showed the strongest association.
In participants whose baseline frailty measurement was conducted before the predementia acceleration period began, the association of frailty scores and dementia risk was positive. These aHRs ranged from 1.18 in the HRS cohort to 1.43 in the NACC cohort.
The ‘Four Pillars’ of Prevention
The good news, investigators said, is that the long trajectory of frailty symptoms preceding dementia onset provides plenty of opportunity for intervention.
To slow the development of frailty, Ward suggested adhering to the “four pillars of frailty prevention and management,” which include good nutrition with plenty of protein, exercise, optimizing medications for chronic conditions, and maintaining a strong social network.
Ward suggested neurologists track frailty in their patients and pointed to a recent article focused on helping neurologists use frailty measures to influence care planning.
Study limitations include the possibility of reverse causality and the fact that investigators could not adjust for genetic risk for dementia.
Unclear Pathway
Commenting on the findings, Lycia Neumann, PhD, senior director of Health Services Research at the Alzheimer’s Association, noted that many studies over the years have shown a link between frailty and dementia. However, she cautioned that a link does not imply causation.
The pathway from frailty to dementia is not 100% clear, and both are complex conditions, said Neumann, who was not part of the study.
“Adopting healthy lifestyle behaviors early and consistently can help decrease the risk of — or postpone the onset of — both frailty and cognitive decline,” she said. Neumann added that physical activity, a healthy diet, social engagement, and controlling diabetes and blood pressure can also reduce the risk for dementia as well as cardiovascular disease.
The study was funded in part by the Deep Dementia Phenotyping Network through the Frailty and Dementia Special Interest Group. Ward and Neumann reported no relevant financial relationships.

Canadian Guideline on Managing Opioid Use Disorder Updated
Canada’s National Guideline for the Clinical Management of Opioid Use Disorder (OUD) has been updated to reflect the latest literature. The new document recommends buprenorphine and methadone as first-line treatments for OUD.
Opioid use and OUD remain the leading causes of drug-related death worldwide. In Canada, the number of apparent opioid-related deaths increased from 2831 in 2016 to 8049 in 2023. Despite the expansion of treatment options, including the lifting of restrictions on methadone prescribing in 2018, there has been a substantial surge in opioid-related harms, the authors wrote.
“OUD and opioid-related harms have devastating outcomes for our communities across Canada,” author Ginette Poulin, MD, a family physician at the University of Manitoba in Winnipeg, Manitoba, Canada, said in a statement. “With the growing dangers associated with the illicit market, we need to ensure we are sharing the most relevant therapeutic tools and up-to-date knowledge to help providers and communities address this complex issue.”
The 2024 update, which was drafted by the Canadian Research Initiative in Substance Matters (CRISM), was published in CMAJ.
Expanding Access
The COVID-19 pandemic marked an increase in opioid-related harms, senior author Julie Bruneau, MD, Canada research chair in addiction medicine and professor of family and emergency medicine at the Université de Montréal, in Quebec, Canada, told this news organization. Access to essential services and support for people with OUD became restricted, and the drug supply became toxic and volatile.
“In March 2018, CRISM published the first Canadian national clinical practice guideline to assist clinicians in making informed decisions regarding the clinical management of OUD, and recommendations were made in light of existing evidence on prioritizing available treatments,” said Bruneau.
“This guideline is intended for use by healthcare providers, including physicians, nurse practitioners, pharmacists, clinical psychologists, social workers, medical educators, and clinical care case managers with or without specialized experience in addiction treatment. We hope it will help expand access to evidence-based interventions for people with OUD beyond tertiary care,” she said.
Bruneau added that integrating first-line opioid agonist treatment into primary care could reduce stigma, increase early screening and patient retention, and help reduce Canada’s opioid crisis.
The CRISM guideline development team carried out a comprehensive systematic review of the literature published from January 1, 2017, to September 14, 2023. The team, which included patients with OUD, drafted and graded their recommendations using the Grading of Recommendations, Assessment, Development and Evaluation approach.
“First, OUD management should be based on a patient-centered approach, which includes respect for the patient’s rights, preferences, and dignity,” said Bruneau.
Highlights of the guideline include the following recommendations:
- Buprenorphine, with or without naloxone, and methadone can be used as standard first-line treatment options.
- Opioid agonist treatment with slow-release oral morphine should be made available and offered as a second-line option.
- Patients with OUD should not be offered withdrawal management as stand-alone treatment because it is associated with increased rates of relapse, morbidity, and mortality.
- Psychosocial treatment, interventions, and supports can be offered as adjunct treatments but should not be a mandatory component of standard treatment for OUD and should not prevent access to opioid agonist therapy.
- Harm reduction strategies should be offered as part of the continuum of care for patients with OUD.
- Pregnant people can be offered buprenorphine or methadone as treatment options.
Treating More Patients
“Too many people die from untreated opioid addiction in Canada,” coauthor Peter Selby, MD, director of medical education at the Centre for Addiction and Mental Health, said in a statement. “We have medicines that help people stop using, but too few patients are treated due to stigma and lack of prescribers knowing what to do. These national guidelines help them use proven medications to not only prevent death but also help people recover.”
“That both buprenorphine and methadone are now to be considered first-line therapy for the management of OUD is an important change to the guideline,” said Abhimanyu Sud, MD, PhD, research chair in primary care and population health systems at Humber River Health and assistant professor of family and community medicine at the University of Toronto. He did not participate in drafting the guidelines.
“There is a lot of good evidence that these agents are effective for the management of OUD. We had this idea that methadone was harder or somehow more unsafe than buprenorphine, and that buprenorphine was therefore a safer therapy that should be used more widely. Now we have very high-potency opioids that are circulating, and methadone, as a strong opioid agonist, has an important role to play. Clinical experience has borne that out, and this is reflected in the guidelines,” said Sud.
“When we treat patients who are using fentanyl, for example, or fentanyl analogs, or they’re not sure what they are using because the drug supply has been so contaminated, you sometimes need another agent. Also, a lot of patients do not respond very well to buprenorphine, so for many people, a full agonist like methadone is needed,” he added.
Giving higher priority to slow-release morphine is a good move, and the drug’s use is likely to be safe when administered by a skilled clinician, said Akash Goel, MD, staff physician in the Department of Anesthesiology and Pain Medicine at St. Michael’s Hospital and assistant professor of anesthesiology and pain medicine at the University of Toronto. Goel was not involved in drafting the guideline.
The updated document will empower patients to make informed decisions about their care, he said. “Buprenorphine, for example, may not be the right selection for all patients. The updated guideline recognizes this. So, for patients who are at risk of failing OUD therapy and going back to using, buprenorphine may not be the best option. The new guideline gives patients the opportunity to have a conversation with their healthcare providers and then decide what’s the best way forward for them.”
The guideline was supported by Health Canada and the Canadian Institutes of Health Research (CIHR) via CRISM. Poulin reported receiving honoraria for presentations from the Master Clinician Alliance and Indivior outside this work. Bruneau reported receiving a CIHR research grant and a grant from Health Canada’s Substance Use and Addictions Program. Outside this work, Bruneau received a National Institutes of Health research grant and consulting fees for Gilead Sciences and AbbVie.

Bruneau added that integrating first-line opioid agonist treatment into primary care could reduce stigma, increase early screening and patient retention, and help reduce Canada’s opioid crisis.
The CRISM guideline development team carried out a comprehensive systematic review of the literature published from January 1, 2017, to September 14, 2023. The team, which included patients with OUD, drafted and graded their recommendations using the Grading of Recommendations, Assessment, Development and Evaluation approach.
“First, OUD management should be based on a patient-centered approach, which includes respect for the patient’s rights, preferences, and dignity,” said Bruneau.
Highlights of the guideline include the following recommendations:
- Buprenorphine, with or without naloxone, and methadone can be used as standard first-line treatment options.
- Opioid agonist treatment with slow-release oral morphine should be made available and offered as a second-line option.
- Patients with OUD should not be offered withdrawal management as stand-alone treatment because it is associated with increased rates of relapse, morbidity, and mortality.
- Psychosocial treatment, interventions, and supports can be offered as adjunct treatments but should not be a mandatory component of standard treatment for OUD and should not prevent access to opioid agonist therapy.
- Harm reduction strategies should be offered as part of the continuum of care for patients with OUD.
- Pregnant people can be offered buprenorphine or methadone as treatment options.
Treating More Patients
“Too many people die from untreated opioid addiction in Canada,” coauthor Peter Selby, MD, director of medical education at the Centre for Addiction and Mental Health, said in a statement. “We have medicines that help people stop using, but too few patients are treated due to stigma and lack of prescribers knowing what to do. These national guidelines help them use proven medications to not only prevent death but also help people recover.”
“That both buprenorphine and methadone are now to be considered first-line therapy for the management of OUD is an important change to the guideline,” said Abhimanyu Sud, MD, PhD, research chair in primary care and population health systems at Humber River Health and assistant professor of family and community medicine at the University of Toronto. He did not participate in drafting the guidelines.
“There is a lot of good evidence that these agents are effective for the management of OUD. We had this idea that methadone was harder or somehow more unsafe than buprenorphine, and that buprenorphine was therefore a safer therapy that should be used more widely. Now we have very high-potency opioids that are circulating, and methadone, as a strong opioid agonist, has an important role to play. Clinical experience has borne that out, and this is reflected in the guidelines,” said Sud.
“When we treat patients who are using fentanyl, for example, or fentanyl analogs, or they’re not sure what they are using because the drug supply has been so contaminated, you sometimes need another agent. Also, a lot of patients do not respond very well to buprenorphine, so for many people, a full agonist like methadone is needed,” he added.
Giving higher priority to slow-release morphine is a good move, and the drug’s use is likely to be safe when administered by a skilled clinician, said Akash Goel, MD, staff physician in the Department of Anesthesiology and Pain Medicine at St. Michael’s Hospital and assistant professor of anesthesiology and pain medicine at the University of Toronto. Goel was not involved in drafting the guideline.
The updated document will empower patients to make informed decisions about their care, he said. “Buprenorphine, for example, may not be the right selection for all patients. The updated guideline recognizes this. So, for patients who are at risk of failing OUD therapy and going back to using, buprenorphine may not be the best option. The new guideline gives patients the opportunity to have a conversation with their healthcare providers and then decide what’s the best way forward for them.”
The guideline was supported by Health Canada and the Canadian Institutes of Health Research (CIHR) via CRISM. Poulin reported receiving honoraria for presentations from the Master Clinician Alliance and Indivior outside this work. Bruneau reported receiving a CIHR research grant and a grant from Health Canada’s Substance Use and Addictions Program. Outside this work, Bruneau received a National Institutes of Health research grant and consulting fees for Gilead Sciences and AbbVie.

Canada’s National Guideline for the Clinical Management of Opioid Use Disorder (OUD) has been updated to reflect the latest literature. The new document recommends buprenorphine and methadone as first-line treatments for OUD.
Opioid use and OUD remain the leading causes of drug-related death worldwide. In Canada, the number of apparent opioid-related deaths increased from 2831 in 2016 to 8049 in 2023. Despite the expansion of treatment options, including the lifting of restrictions on methadone prescribing in 2018, there has been a substantial surge in opioid-related harms, the authors wrote.
“OUD and opioid-related harms have devastating outcomes for our communities across Canada,” author Ginette Poulin, MD, a family physician at the University of Manitoba in Winnipeg, Manitoba, Canada, said in a statement. “With the growing dangers associated with the illicit market, we need to ensure we are sharing the most relevant therapeutic tools and up-to-date knowledge to help providers and communities address this complex issue.”
The 2024 update, which was drafted by the Canadian Research Initiative in Substance Matters (CRISM), was published in CMAJ.
Expanding Access
The COVID-19 pandemic marked an increase in opioid-related harms, senior author Julie Bruneau, MD, Canada research chair in addiction medicine and professor of family and emergency medicine at the Université de Montréal, in Quebec, Canada, told this news organization. Access to essential services and support for people with OUD became restricted, and the drug supply became toxic and volatile.
“In March 2018, CRISM published the first Canadian national clinical practice guideline to assist clinicians in making informed decisions regarding the clinical management of OUD, and recommendations were made in light of existing evidence on prioritizing available treatments,” said Bruneau.
“This guideline is intended for use by healthcare providers, including physicians, nurse practitioners, pharmacists, clinical psychologists, social workers, medical educators, and clinical care case managers with or without specialized experience in addiction treatment. We hope it will help expand access to evidence-based interventions for people with OUD beyond tertiary care,” she said.

SCD: Can Atrial Arrhythmias Predict Strokes?
TOPLINE:
METHODOLOGY:
- A total of 130 adult patients with SCD were included in the DREPACOEUR prospective registry from November 2018 to November 2022.
- The patients underwent a comprehensive cardiac evaluation, including 24-hour electrocardiogram monitoring, echocardiography, and laboratory tests.
- The primary endpoint was the occurrence of atrial arrhythmias, defined by excessive supraventricular ectopic activity or any recent history of atrial fibrillation.
- Patients with a history of stroke or transient ischemic attack were also included in the PCDREP prospective registry for further assessment.
- Written informed consent was collected from all participating patients, and the study was approved by the ethics committee.
TAKEAWAY:
- Atrial arrhythmias were found in 26% of patients with SCD, with a significant association with stroke history (P = .001).
- Age and left atrial volume were independently associated with atrial arrhythmias, with optimal cutoffs of 47 years and 55 mL/m2, respectively.
- Patients with atrial arrhythmias had higher diastolic blood pressure, worse kidney function, and higher NT pro-BNP levels than those without arrhythmias.
- Atrial arrhythmias were associated with an increased risk for stroke unrelated to cerebral vasculopathy or other defined causes (odds ratio, 6.6; P = .009).
“Atrial arrhythmias were found in 26% of patients with sickle cell anemia, with a significant association with stroke history,” wrote the authors of the study. In a commentary published concurrently, Jonathan Uniat, MD, of Children’s Hospital Los Angeles in California, wrote, “Early detection and treatment of atrial arrhythmias may help prevent strokes in this population.”
SOURCE:
The study was led by Thomas d’Humières, Henri Mondor Hospital in Créteil, France. It was published online on November 12 in Blood Advances.
LIMITATIONS:
This study was a pilot prospective study and was underpowered with atrial arrhythmias occurring in only 34 patients. The population was relatively old for sickle cell anemia (45 years), and the study was biased because patients were selected based on clinical criteria indicative of underlying cardiovascular abnormalities. The population was heterogeneous in terms of antiarrhythmic therapy, and overall, at an advanced stage of the disease with frequent organ complications.
DISCLOSURES:
The study was supported by grants from FHU-SENEC. Pablo Bartolucci received grants from Addmedica, the Fabre Foundation, Novartis, and Bluebird in the past 36 months; received consulting fees from Addmedica, Novartis, Roche, GBT, Bluebird, Emmaus, Hemanext, and Agios; received honoraria for lectures from Novartis, Addmedica, and Jazz Pharmaceuticals; and reported being a member of the Novartis steering committee and cofounder of Innovhem.

Faster Brain Atrophy Linked to MCI
While some brain atrophy is expected in aging, high levels of atrophy in the white matter and high enlargement in the ventricles are associated with earlier progression from normal cognition to MCI, the study found. The researchers also identified diabetes and atypical levels of amyloid beta protein in the cerebrospinal fluid as risk factors for brain atrophy and MCI.
For their research, published online on JAMA Network Open, Yuto Uchida, MD, PhD, and his colleagues at the Johns Hopkins University School of Medicine in Baltimore, Maryland, looked at data for 185 individuals (mean age, 55.4 years; 63% women) who were cognitively normal at baseline and followed for a median of 20 years.
All had been enrolled in a longitudinal cohort study on biomarkers of cognitive decline conducted at Johns Hopkins. Each participant underwent a median of five structural MRI studies during the follow-up period as well as annual cognitive testing. Altogether 60 individuals developed MCI, with eight of them progressing to dementia.
“We hypothesized that annual rates of change of segmental brain volumes would be associated with vascular risk factors among middle-aged and older adults and that these trends would be associated with the progression from normal cognition to MCI,” Uchida and colleagues wrote.
Uniquely Long Follow-Up
Most longitudinal studies using structural MRI count a decade or less of follow-up, the study authors noted. This makes it difficult to discern whether the annual rates of change of brain volumes are affected by vascular risk factors or are useful in predicting MCI, they said. Individual differences in brain aging make population-based studies less informative.
This study’s long timeframe allowed for tracking of brain changes “on an individual basis, which facilitates the differentiation between interindividual and intraindividual variations and leads to more accurate estimations of rates of brain atrophy,” Uchida and colleagues wrote.
People with high levels of atrophy in the white matter and enlargement in the ventricles saw earlier progression to MCI (hazard ratio [HR], 1.86; 95% CI, 1.24-2.49; P = .001). Diabetes mellitus was associated with progression to MCI (HR, 1.41; 95% CI, 1.06-1.76; P = .04), as was a low CSF Abeta42:Abeta40 ratio (HR, 1.48; 95% CI, 1.09-1.88; P = .04).
People with both diabetes and an abnormal amyloid profile were even more vulnerable to developing MCI (HR, 1.55; 95% CI, 1.13-1.98; P = .03). This indicated “a synergic association of diabetes and amyloid pathology with MCI progression,” Uchida and colleagues wrote, noting that insulin resistance has been shown to promote the formation of amyloid plaques, a hallmark of Alzheimer’s disease.
The findings also underscore that “white matter volume changes are closely associated with cognitive function in aging, suggesting that white matter degeneration may play a crucial role in cognitive decline,” the authors noted.
Uchida and colleagues acknowledged the modest size and imbalanced sex ratio of their study cohort as potential weaknesses, as well as the fact that the imaging technologies had changed over the course of the study. Most of the participants were White with family histories of dementia.
Findings May Lead to Targeted Interventions
In an editorial comment accompanying Uchida and colleagues’ study, Shohei Fujita, MD, PhD, of Massachusetts General Hospital, Boston, said that, while a more diverse population sample would be desirable and should be sought for future studies, the results nonetheless highlight “the potential of long-term longitudinal brain MRI datasets in elucidating the interplay of risk factors underlying cognitive decline and the potential benefits of controlling diabetes to reduce the risk of progression” along the Alzheimer’s disease continuum.
The findings may prove informative, Fujita said, in developing “targeted interventions for those most susceptible to progressive brain changes, potentially combining lifestyle modifications and pharmacological treatments.”
Uchida and colleagues’ study was funded by the Alzheimer’s Association, the National Alzheimer’s Coordinating Center, and the National Institutes of Health. The study’s corresponding author, Kenichi Oishi, disclosed funding from the Richman Family Foundation, Richman, the Sharp Family Foundation, and others. Uchida and Fujita reported no relevant financial conflicts of interest.

Smokeless Tobacco, Areca Nut Chewing Behind 1 in 3 Oral Cancers: IARC Report
“Smokeless tobacco and areca nut products are available to consumers in many different forms across the world, but consuming smokeless tobacco and areca nut is linked to multiple diseases, including oral cancer,” Harriet Rumgay, PhD, a scientist in the Cancer Surveillance Branch at IARC and first author of the study in Lancet Oncology, said in a news release.
Worldwide, about 300 million people use smokeless tobacco and 600 million people use areca (also called betel) nut, one of the most popular psychoactive substances in the world after nicotine, alcohol, and caffeine. Smokeless tobacco products are consumed without burning and can be chewed, sucked, inhaled, applied locally, or ingested. Areca nut is the seed of the areca palm and can be consumed in various forms.
“Our estimates highlight the burden these products pose on health care and the importance of prevention strategies to reduce consumption of smokeless tobacco and areca nut,” Rumgay said.
According to the new report, in 2022, an estimated 120,200 of the 389,800 (30.8%) global cases of oral cancer were attributable to these products.
More than three quarters (77%) of attributable cases were among men and about one quarter (23%) among women.
The vast majority (96%) of all oral cancer cases caused by smokeless tobacco and areca nut use occurred in low- and middle-income countries.
Regions with the highest burden of oral cancers from these products were Southcentral Asia — with 105,500 of 120,200 cases (nearly 88%), including 83,400 in India, 9700 in Bangladesh, 8900 in Pakistan, and 1300 in Sri Lanka — followed by Southeastern Asia with a total of 3900 cases (1600 in Myanmar, 990 in Indonesia, and 785 in Thailand) and East Asia with 3300 cases (3200 in China).
Limitations and Action Points
The authors noted a limitation of the analysis is not accounting for the potential synergistic effects of combined use of smokeless tobacco or areca nut products with other risk factors for oral cancer, such as smoking tobacco or drinking alcohol.
The researchers explained that combined consumption of smokeless tobacco or areca nut, smoked tobacco, and alcohol has a “multiplicative effect” on oral cancer risk, with reported odds ratios increasing from 2.7 for smokeless tobacco only, 7.0 for smoked tobacco only, and 1.6 for alcohol only to 16.2 for all three exposures (vs no use).
However, the proportion of people who chewed tobacco and also smoked in countries with high smokeless tobacco or areca nut use was small. In India, for example, 6% of men and 0.5% of women in 2016-2017 were dual users of both smoked and smokeless tobacco, compared with 23% of men and 12% of women who only used smokeless tobacco.
Overall, curbing or preventing smokeless tobacco and areca nut use could help avoid many instances of oral cancer.
Despite “encouraging trends” in control of tobacco smoking in many regions of the world over the past two decades, progress in reducing the prevalence of smokeless tobacco consumption has stalled in many countries that are major consumers, the authors said.
Compounding the problem, areca nut does not fall within the WHO framework of tobacco control and there are very few areca nut control policies worldwide.
Smokeless tobacco control must be “prioritized” and a framework on areca nut control should be developed with guidelines to incorporate areca nut prevention into cancer control programs, the authors concluded.

“Smokeless tobacco and areca nut products are available to consumers in many different forms across the world, but consuming smokeless tobacco and areca nut is linked to multiple diseases, including oral cancer,” Harriet Rumgay, PhD, a scientist in the Cancer Surveillance Branch at IARC and first author of the study in Lancet Oncology, said in a news release.
Worldwide, about 300 million people use smokeless tobacco and 600 million people use areca (also called betel) nut, one of the most popular psychoactive substances in the world after nicotine, alcohol, and caffeine. Smokeless tobacco products are consumed without burning and can be chewed, sucked, inhaled, applied locally, or ingested. Areca nut is the seed of the areca palm and can be consumed in various forms.
“Our estimates highlight the burden these products pose on health care and the importance of prevention strategies to reduce consumption of smokeless tobacco and areca nut,” Rumgay said.
According to the new report, in 2022, an estimated 120,200 of the 389,800 (30.8%) global cases of oral cancer were attributable to these products.
More than three quarters (77%) of attributable cases were among men and about one quarter (23%) among women.
The vast majority (96%) of all oral cancer cases caused by smokeless tobacco and areca nut use occurred in low- and middle-income countries.
Regions with the highest burden of oral cancers from these products were Southcentral Asia — with 105,500 of 120,200 cases (nearly 88%), including 83,400 in India, 9700 in Bangladesh, 8900 in Pakistan, and 1300 in Sri Lanka — followed by Southeastern Asia with a total of 3900 cases (1600 in Myanmar, 990 in Indonesia, and 785 in Thailand) and East Asia with 3300 cases (3200 in China).

Vitamin K Supplementation Reduces Nocturnal Leg Cramps in Older Adults
TOPLINE:
Vitamin K supplementation significantly reduced the frequency, intensity, and duration of nocturnal leg cramps in older adults. No adverse events related to vitamin K were identified.
METHODOLOGY:
- Researchers conducted a multicenter, double-blind, placebo-controlled randomized clinical trial in China from September 2022 to December 2023.
- A total of 199 participants aged ≥ 65 years with at least two documented episodes of nocturnal leg cramps during a 2-week screening period were included.
- Participants were randomized in a 1:1 ratio to receive either 180 μg of vitamin K (menaquinone 7) or a placebo daily for 8 weeks.
- The primary outcome was the mean number of nocturnal leg cramps per week, while secondary outcomes were the duration and severity of muscle cramps.
- The ethics committees of Third People’s Hospital of Chengdu and Affiliated Hospital of North Sichuan Medical College approved the study, and all participants provided written informed consent.
TAKEAWAY:
- Vitamin K group experienced a significant reduction in the mean weekly frequency of cramps (mean difference, 2.60 [SD, 0.81] to 0.96 [SD, 1.41]) compared with the placebo group, which maintained a mean weekly frequency of 3.63 (SD, 2.20) (P < .001).
- The severity of nocturnal leg cramps decreased more in the vitamin K group (mean difference, −2.55 [SD, 2.12] points) than in the placebo group (mean difference, −1.24 [SD, 1.16] points).
- The duration of nocturnal leg cramps also decreased more in the vitamin K group (mean difference, −0.90 [SD, 0.88] minutes) than in the placebo group (mean difference, −0.32 [SD, 0.78] minutes).
- No adverse events related to vitamin K use were identified, indicating a good safety profile for the supplementation.
IN PRACTICE:
“Given the generally benign characteristics of NLCs, treatment modality must be both effective and safe, thus minimizing the risk of iatrogenic harm,” the study authors wrote.
SOURCE:
This study was led by Jing Tan, MD, the Third People’s Hospital of Chengdu in Chengdu, China. It was published online on October 28 in JAMA Internal Medicine.
LIMITATIONS:
This study did not investigate the quality of life or sleep, which could have provided additional insights into the impact of vitamin K on nocturnal leg cramps. The relatively mild nature of nocturnal leg cramps experienced by the participants may limit the generalizability of the findings to populations with more severe symptoms.

Does Radiation Timing Affect QOL After Prostate Surgery?
TOPLINE:
METHODOLOGY:
- Delaying radiotherapy after prostatectomy can help avoid overtreatment and mitigate genitourinary and erectile toxic effects. However, few studies have compared long-term patient-reported health-related quality-of-life outcomes on the basis of the timing of postprostatectomy radiotherapy.
- Researchers evaluated 1203 men (median age, 60.5 years; 92% were White and 6.8% were Black) with localized prostate cancer who underwent radical prostatectomy from the PROST-QA (2003-2006) and RP2 Consortium (2010-2013). Among these patients, 1082 underwent surgery only, 57 received early radiotherapy (within 12 months of surgery), and 64 underwent late radiotherapy (12 months or more after surgery).
- Patients who received early radiotherapy were more likely to receive androgen deprivation therapy than those who underwent late radiotherapy (40.4% vs 12.5%; P < .001).
- Primary outcome was health-related quality of life measured using the Expanded Prostate Cancer Index Composite at baseline, 2, 6, and 12 months, and annually after that. Health-related quality-of-life measures included sexual function, urinary incontinence, urinary irritation and/or obstruction, and bowel or rectal function.
- The median follow-up duration was 85.6 months.
TAKEAWAY:
- Postprostatectomy radiotherapy was associated with a significantly greater decline in health-related quality of life across all domains, including sexual function and urinary incontinence.
- Patients who received early radiation initially experienced worse urinary incontinence and sexual health, compared with patients in the late group, but the early group also had higher-risk disease and were more likely to receive concurrent androgen deprivation therapy.
- In the long term, the early radiotherapy group experienced more pronounced recovery of sexual function, urinary irritation, and urinary incontinence than the late radiotherapy group.
- Ultimately, patients in the early radiotherapy group had similar, potentially better, long-term health-related quality-of-life domain scores than those in the late group over the long term. For instance, the likelihood of being pad free increased for patients treated early with radiation, while it decreased for those treated late. In patients who received early radiation, the rate of freedom from pad use increased from 39% before radiation to 67% at the sixth follow-up visit after radiation, while it decreased from 73% to 48% in those who received late radiation.
IN PRACTICE:
“Long-term patient-reported sexual, incontinence, and urinary irritative outcomes did not significantly differ between early vs late postprostatectomy [radiotherapy],” the authors said. In fact, “men receiving early [radiation] experienced greater recovery of these toxicity domains and achieved similar, and possibly better, domain scores as those receiving late [radiation] at long-term follow-up.” Overall, “these results may help guide treatment counseling and support consideration of early [radiotherapy] after prostatectomy for men at particularly high risk of recurrence and metastasis.”
SOURCE:
The study, led by Sagar A. Patel, MD, MSc, Emory University in Atlanta, was published online in JAMA Network Open.
LIMITATIONS:
The early and late postprostatectomy radiotherapy groups were relatively small and underpowered to detect statistically significant differences between groups. The study has a nonrandomized design, which may introduce unaccounted for imbalances among the different groups. The study did not directly compare health-related quality of life between patients receiving adjuvant vs salvage radiotherapy.
DISCLOSURES:
This study received funding from National Institutes of Health grants and the Paul Calabresi Career Development Award for Clinical Oncology. Several authors reported receiving personal fees, grants, and having other ties with various sources. Additional disclosures are noted in the original article.

Study Finds No Significant Effect of Low-Dose Oral Minoxidil on BP
TOPLINE:
but is associated with a slight increase in heart rate and a 5% incidence of hypotensive symptoms.
METHODOLOGY:
- Researchers conducted a systematic review and meta-analysis of 16 studies, which involved 2387 patients with alopecia (60.7% women) who received minoxidil, a vasodilator originally developed as an antihypertensive, at doses of 5 mg or less per day.
- Outcomes included changes in mean arterial pressure, systolic BP, diastolic BP, and heart rate.
- Mean differences were calculated between pretreatment and posttreatment values.
TAKEAWAY:
- Hypotensive symptoms were reported in 5% patients, with no significant hypotensive episodes. About 1.8% patients experienced lightheadedness or syncope, 1.2% experienced dizziness, 0.9% had tachycardia, and 0.8% had palpitations.
- LDOM did not significantly alter systolic BP (mean difference, –0.13; 95% CI, –2.67 to 2.41), diastolic BP (mean difference, –1.25; 95% CI, –3.21 to 0.71), and mean arterial pressure (mean difference, –1.92; 95% CI, –4.00 to 0.17).
- LDOM led to a significant increase in heart rate (mean difference, 2.67 beats/min; 95% CI, 0.34-5.01), a difference the authors wrote would “likely not be clinically significant for most patients.”
- Hypertrichosis was the most common side effect (59.6%) and reason for stopping treatment (accounting for nearly 35% of discontinuations).
IN PRACTICE:
“LDOM appears to be a safe treatment for alopecia with no significant impact on blood pressure,” the authors wrote, noting that the study “addresses gaps in clinical knowledge involving LDOM.” Based on their results, they recommended that BP and heart rate “do not need to be closely monitored in patients without prior cardiovascular risk history.”
SOURCE:
The study was led by Matthew Chen, BS, Stony Brook Dermatology in New York. It was published online in The Journal of the American Academy of Dermatology.
LIMITATIONS:
The studies included had small sample sizes and retrospective designs, which may limit the reliability of the findings. Additional limitations include the absence of control groups, a potential recall bias in adverse effect reporting, and variability in dosing regimens and BP monitoring.
DISCLOSURES:
The authors reported no external funding or conflicts of interest.

TOPLINE:
but is associated with a slight increase in heart rate and a 5% incidence of hypotensive symptoms.
METHODOLOGY:
- Researchers conducted a systematic review and meta-analysis of 16 studies, which involved 2387 patients with alopecia (60.7% women) who received minoxidil, a vasodilator originally developed as an antihypertensive, at doses of 5 mg or less per day.
- Outcomes included changes in mean arterial pressure, systolic BP, diastolic BP, and heart rate.
- Mean differences were calculated between pretreatment and posttreatment values.
TAKEAWAY:
- Hypotensive symptoms were reported in 5% patients, with no significant hypotensive episodes. About 1.8% patients experienced lightheadedness or syncope, 1.2% experienced dizziness, 0.9% had tachycardia, and 0.8% had palpitations.
- LDOM did not significantly alter systolic BP (mean difference, –0.13; 95% CI, –2.67 to 2.41), diastolic BP (mean difference, –1.25; 95% CI, –3.21 to 0.71), and mean arterial pressure (mean difference, –1.92; 95% CI, –4.00 to 0.17).
- LDOM led to a significant increase in heart rate (mean difference, 2.67 beats/min; 95% CI, 0.34-5.01), a difference the authors wrote would “likely not be clinically significant for most patients.”
- Hypertrichosis was the most common side effect (59.6%) and reason for stopping treatment (accounting for nearly 35% of discontinuations).
IN PRACTICE:
“LDOM appears to be a safe treatment for alopecia with no significant impact on blood pressure,” the authors wrote, noting that the study “addresses gaps in clinical knowledge involving LDOM.” Based on their results, they recommended that BP and heart rate “do not need to be closely monitored in patients without prior cardiovascular risk history.”
SOURCE:
The study was led by Matthew Chen, BS, Stony Brook Dermatology in New York. It was published online in The Journal of the American Academy of Dermatology.
LIMITATIONS:
The studies included had small sample sizes and retrospective designs, which may limit the reliability of the findings. Additional limitations include the absence of control groups, a potential recall bias in adverse effect reporting, and variability in dosing regimens and BP monitoring.
DISCLOSURES:
The authors reported no external funding or conflicts of interest.

Fibroids: Medical Therapy Not Hysterectomy Should Be First Treatment Choice Interventional Options Case Study
Although hysterectomy remains the most common procedure for treating fibroids and fibroids are the leading indication for hysterectomy, its long-term sequelae make less invasive alternatives the better choice for managing most of these myometrial masses, an invited clinical practice paper in the New England Journal of Medicine (NEJM) asserts.
The practice summary also calls for earlier identification and treatment of fibroid disease and may raise awareness among general gynecologists and primary care physicians less familiar with newer treatments.
Based on a review of evidence and existing formal guidelines, the paper urges wider use of uterus-sparing approaches such as hormone therapy, uterine-artery embolization, focused ultrasound ablation, and radiofrequency ablation. Authored by ob.gyns. Elizabeth A. Stewart, MD, and Shannon K. Laughlin-Tommaso, MD, MPH, of the Mayo Clinic in Rochester, Minnesota, the document also features textbook-style diagrams illustrating procedures.
“To clarify, this is not a new guidance but an invited clinical practice paper,” Laughlin-Tommaso told this news organization. “I believe NEJM recognized the gap in knowledge among all providers, for early diagnosis of uterine fibroids, especially in young patients and those presenting with anemia.”
The less invasive treatments highlighted in the paper can help women recover faster and resume their normal activities more quickly, said Laughlin-Tommaso. “Additionally, many studies have now shown that there are health benefits to keeping the uterus and the ovaries.”
Despite multiple uterine-sparing options, however, a recent study in a commercially insured population found nearly 60% of fibroid patients undergoing hysterectomy had never received a prior conservative treatment.
Why hysterectomy for a benign condition? Hysterectomy, which is universally available in ob.gyn. practices, makes decision-making easier for medical providers and patients, Laughlin-Tommaso explained. “It’s the only treatment that is definitive in that patients will not have bleeding or fibroids in the future and providers don’t have to determine which fibroids to treat or remove.”
More common in Black women, fibroids affect up to 80% of persons with a uterus during their lifetime and up to 50% have symptoms such as heavy and prolonged menstrual bleeding, anemia-associated fatigue, pelvic pressure, and menstrual and nonmenstrual pain, the authors noted. These lesions can also compress nearby structures causing painful intercourse, constipation, and urinary frequency, urgency, or retention.
In 2021 the American College of Obstetricians and Gynecologists issued a practice bulletin on the management of symptomatic uterine leiomyomas, similarly endorsing individualized care that accounts for the desire to preserve fertility or the uterus, increase quality of life, and reduce symptoms. It, too, recommended medical management as first-line treatment for symptomatic fibroids.
“This paper will be helpful for clinicians by covering some of the newer options such as gonadotropin-releasing hormone antagonists introduced in the past 5 years and tailoring treatment to patients depending on whether they still want to conceive,” Sandra M. Hurtado, MD, an ob.gyn. and an assistant professor at UTHealth Houston Medical Center and McGovern Medical School in Houston, Texas, said in an interview. “And the illustrations will be useful to doctors who are not gynecologists and will help to explain the interventional options to patients,” added Hurtado, who was not involved in the paper.
Offering another outside perspective on the paper, Charles J. Ascher-Walsh, MD, senior system vice chair for gynecology and division director of urogynecology in the Raquel and Jaime Gilinski Department of Obstetrics, Gynecology and Reproductive Science at Mount Sinai in New York City, called it a useful though not new summary. Reaching the wider audience of NEJM may raise awareness of newer fibroid therapies among general, nonspecialist ob.gyns., whose practices may concentrate largely on obstetrics, he added, “and the excellent illustrations clarify the treatment options.” In his view, broader awareness may increase much-needed funding for this neglected area of research.
Among the paper’s recommendations:
Diagnosis
Pelvic ultrasonography is the most cost-effective imaging method, providing information on size, location, and number of fibroids and ruling out adnexal masses. It is limited, however, by less-accurate resolution if the uterine volume is greater than 375 mL or if fibroids number more than four.
Medical Alternatives to Hysterectomy
Early diagnosis and first-line medical therapies are recommended.
Contraceptive hormones to control heavy menstrual bleeding are the first step in most algorithms for treating fibroid-related bleeding, despite low-quality evidence.
Nonsteroidal anti-inflammatory agents and tranexamic acid during menstruation also limit heavy menses but have more evidence of efficacy for idiopathic heavy menses.
Gonadotropin-releasing hormone (GnRH) agonists in depot form are approved for short-term preoperative therapy. While they cause amenorrhea in nearly 90% of patients and reduce uterine volume by 30%-60%, they have a high incidence of hypogonadal symptoms, including bone loss and hot flushes. They also cause a “steroidal flare” when the stored gonadotropins are released and cause subsequent heavy menstrual bleeding with the rapid decrease in estrogen levels.
Oral GnRH antagonist combinations are a major therapeutic advance, pairing a GnRH antagonist (such as elagolix or relugolix, which rapidly inhibit ovarian steroidogenesis) with estradiol and progestin at doses equivalent to systemic levels in the early follicular phase of the menstrual cycle.
In clinical trials these combinations decreased heavy menstrual bleeding by 50%-75%, pain by 40%-50%, and bulk-related symptoms through a 10% decrease in uterine volume. Side effects are few, with hot flushes, headaches, and nausea occurring in fewer than 20% of participants.
Smaller fibroids in the submucosal to intramural spaces can be treated transcervically, while larger lesions of any type or smaller subserosa fibroids are treated abdominally.
Uterine-artery embolization uses minimally invasive radiologically guided catheterization to release embolic particles directly into both uterine arteries. This process causes ischemic infarction of the fibroids and decreases bleeding, pain, and bulk-related symptoms.
Other procedures shrink individual fibroids with energy that creates coagulative necrosis. These include focused ultrasound ablation (with MRI or ultrasound guidance) and radiofrequency ablation (with laparoscopic or transcervical ultrasound guidance).
Unlike uterine-artery embolization, which treats all fibroids concurrently, these therapies require individual targeting of fibroids.
Radiofrequency ablation can be done concurrently with other surgical therapies, such as laparoscopic excision of endometriosis or hysteroscopic myomectomy.
Myomectomy, or the surgical removal of fibroids, is most often used in persons actively seeking pregnancy or having very large fibroids in whom shrinkage would be inadequate. Most guidelines recommend surgical excision rather than shrinking procedures to optimize fertility. However, myomectomy often commits patients to future cesarean section, which increases pregnancy-related morbidity.
Although myomectomy is seen as superior to uterine-artery embolization for improving quality of life, both approaches provide substantial symptom relief.
Recurrence
Incidence of recurring fibroids is high, with, for example, new fibroids developing in approximately 50% of persons within 5 years of myomectomy.
Earlier this year, a large cohort study reported that myomectomy was best for avoiding reintervention after surgical leiomyoma management.
Reintervention rates vary according to procedure, patient age, disease extent, and symptoms and can be as high as 33% up to 5 years after treatment, with lower percentages seen among persons older than 45 years of age.
Hysterectomy
Minimally invasive hysterectomy is recommended. Drawbacks to hysterectomy include perioperative risk and concomitant oophorectomy, which was common until the early 2000s when large cohort studies showed elevated risks of death, cardiovascular disease, dementia, and other illnesses compared with hysterectomy plus ovarian conservation. Oophorectomy but not hysterectomy rates have since decreased.
Still needing study, according to Laughlin-Tommaso are the underlying reasons for health disparities in fibroids, especially among Black and Latina individuals. “Some studies have found associations with vitamin D deficiency and with stress and racism,” she said.
Looking ahead, the authors stressed the need for a fibroid risk-prediction model, a staging system, and large randomized trials of treatment effectiveness. Also needed are methods for primary and secondary prevention. “Earlier screening and medical treatment in primary care settings could potentially minimize morbidity and the incidence of unnecessary hysterectomies, and primary care–based screening trials are warranted,” they wrote.
In addition to procedural illustrations the practice document includes a vignette of a 33-year-old never-pregnant Black woman (but desiring motherhood) with heavy menstrual bleeding, abdominal bloating, and non–iron deficiency anemia. Evaluation for thalassemia and sickle cell anemia is negative, but ultrasonography reveals an enlarged uterus with multiple fibroids and normal ovaries.
In line with the clinical review, the authors prescribe oral GnRH agonist combination therapy, plus iron and multivitamin supplementation, and recommend annual reassessment — earlier if pregnancy is desired or if symptoms escalate. Since the patient prioritizes fertility, hysterectomy would be appropriate only if she had biopsy-proven cancer.
The authors received no external funding for this practice paper, but both have funding from the National Institutes of Health for fibroid research. Laughlin-Tommaso reported royalties from UpToDate. Stewart reported research support from the Agency for Healthcare Research and Quality, and speaking, data-monitoring, and consulting fees for various private companies, including AbbVie, Anylam Pharmaceuticals, ASKA Pharma, and Myovant Sciences. She holds a patent on treatment for abnormal uterine bleeding and has been involved in CME for various medical educational agencies. Hurtado and Ascher-Walsh had no relevant conflicts of interest to declare.
