A decline in antibiotic-resistant bacteria has been observed in European countries that have curbed the use of antibiotics in both animals and humans, revealed the fourth joint interagency antimicrobial consumption and resistance analysis report.

The report was published by the European Centre for Disease Prevention and Control, the European Food Safety Authority, and the European Medicines Agency. Its findings were derived from an integrated analysis of the potential relationship between antimicrobial consumption (AMC) by humans and animals and the occurrence of antimicrobial resistance (AMR) using data collected between 2019 and 2021.
 

A Real Threat

AMR poses a significant threat to public and animal health, causing more than 35,000 deaths annually in the European Union (EU) and the European Economic Area. It also imposes a substantial economic burden on European healthcare systems, amounting to approximately €11.7 billion per year.

To address this challenge, the Council of the European Union recommended concerted and sustained efforts to achieve a 20% reduction in AMC in humans (compared with 2019 levels) and a 50% reduction in food-producing animals (compared with 2018 levels) by 2030. These targets are outlined in the European Commission’s Farm to Fork strategy.
 

It Really Works

Analysis of the trends of AMC and AMR in Escherichia coli from humans and food-producing animals, conducted for the first time, revealed that the susceptibility of E coli to antimicrobials in humans and animals increases with an overall decrease in the consumption of antibiotics.

Concurrent trends in AMC and AMR from 2014 to 2021 were also assessed. AMC in both human and animal sectors, measured in mg/kg of estimated biomass, was compared at country and European levels. In 2021, human AMC totaled 125.0 mg/kg of biomass, while food-producing animals registered 92.6 mg/kg of biomass.

Over the 2014-2021 period, total AMC in food-producing animals decreased by 44%, while in humans, it remained relatively stable. The consumption of certain antimicrobials was positively associated with resistance to those substances in bacteria from both humans and food-producing animals.

The report also highlighted that E coli resistance is linked in humans to the use of carbapenems, third- and fourth-generation cephalosporins, and quinolones and in food-producing animals to the administration of quinolones, polymyxins, aminopenicillins, and tetracyclines. Further, a connection exists between bacterial resistance in humans and food-producing animals, particularly for bacterial species such as Campylobacter jejuni and C coli.

The findings suggest that measures to reduce AMC in both food-producing animals and humans have been effective in many countries. However, reinforcing these measures is crucial to maintain and further advance reductions in AMC.
 

More Work

Aligned with the European Commission’s One Health holistic and coordinated approach to managing the human and veterinary sectors together, the European agencies advocate for:

• Sustained efforts to combat AMR at national, EU, and global levels.
• Coordinated surveillance of antibiotic use and AMR in both human and animal sectors.
• Continued research in the field of AMR.

The statistical code used to conduct these analyses was made publicly available in order to support further research analyses.

TOPLINE: 

Accelerometer-measured physical activity (PA), whether light, moderate, or vigorous, is associated with lower risk for heart failure (HF) in older women while more sedentary time is associated with higher HF risk in these women, results of a new study suggest. 

METHODOLOGY:

• The analysis included 5951 women aged 63-99 years (mean age, 78.6 years), including 33.7% Black, 17.2% Hispanic, and 49.2% White individuals without HF from the Objective Physical Activity and Cardiovascular Health (OPACH) study, an ancillary to the Women’s Health Initiative Long-Life Study.
• Participants wore an accelerometer on their hip 24 hours a day for up to 7 consecutive days except when in water, kept nightly sleep logs, completed questionnaires to provide information on medical history and sociodemographic and lifestyle factors, and self-rated their general health status.
• Researchers recorded their use of assistive walking devices; determined body mass index as well as blood pressure; obtained fasting serum glucose, total and high-density lipoprotein cholesterol, triglyceride, and high-sensitivity C-reactive protein concentrations; and scored participants’ multimorbidity.
• They determined intensity-specific PA using vector magnitude acceleration cut points (light PA, 19-518 counts/15 s; moderate to vigorous PA [MVPA], > 518) and steps per day using dedicated software, and they quantified sedentary time (total and mean bout duration).
• The primary outcome was overall self-reported HF later adjudicated by physicians using medical record reviews; secondary endpoints were heart failure with reduced ejection fraction (HFrEF) and preserved EF (HFpEF), classified by an EF of < 45% or 45% or > 45%, respectively, after cardiac imaging.

TAKEAWAY:

• A total of 407 HF cases (including 257 HFpEF and 110 HFrEF) were identified during a mean of 7.5 years of follow-up.
• HFrEF was not associated with PA measures in the fully adjusted model (which controlled extensively for health and physical functioning status), but overall HF and HFpEF were inversely associated with total PA (per 1-standard deviation [SD] increment: hazard ratio [HR] 0.85; 95% CI, 0.75-0.95 and HR, 0.78; 95% CI, 0.67-0.91, respectively), light PA (HR, 0.88; 95% CI, 0.78-0.98 and HR, 0.80; 95% CI, 0.70-0.93, respectively) and MVPA (HR, 0.84; 95% CI, 0.73-0.97 and HR, 0.85; 95% CI, 0.72-1.01, respectively).
• With regard to daily steps, each 1-SD increment was associated with a significant 26% lower risk for overall HF (HR 0.74; 95% CI, 0.63-0.88) and 29% lower risk for HFpEF (HR, 0.71; 95% CI, 0.57-0.88), with these inverse risks becoming significant at about 2000 steps/d, “far less than the often touted 10,000 steps/d for promoting health benefits,” noted the authors.
• Total sedentary time was positively associated (per 1 SD in the fully adjusted model) with risks of overall HF (HR, 1.17; 95% CI, 1.04-1.33) and HFpEF (HR, 1.29; 95% CI, 1.10-1.51) but not HFrEF; mean sedentary bout duration was significantly inversely associated with HFrEF (per 1 SD: HR, 0.76; 95% CI, 0.61-0.97), although the relatively small number of cases at the extremes of bout duration may contribute to this unexpected inverse association, said the authors.

IN PRACTICE:

The implications of promoting PA, regardless of intensity, for primary HFpEF prevention in later life, “has profound public health and clinical relevance,” the authors concluded. They noted that HFpEF is a “burgeoning epidemic” that disproportionately affects women and minorities with limited available therapies.

STUDY DETAILS:

The study, led by Michael J. LaMonte, PhD, MPH, University at Buffalo-SUNY, Buffalo, New York, was published online on February 21, 2024, in JAMA Cardiology.

LIMITATIONS:

There was only a single accelerometer assessment of PA and sedentary exposures and relatively small numbers of HFrEF cases, which restricted analytic precision. Although researchers controlled for several established vascular biomarkers, they did not have HF-specific measures such as cardiac troponin or N-terminal pro–brain natriuretic peptide. It’s unknown if the findings can be generalized to men and populations dissimilar to women in OPACH.

DISCLOSURES:

The study was funded in part by the National Heart, Lung, and Blood Institute, National Institutes of Health, and US Department of Health and Human Services. LaMonte reported receiving grants from the National Institutes of Health during the conduct of the study; see paper for disclosures of the other authors.

This transcript has been edited for clarity.

Joseph R. Berger, MD: Hi. I'm Dr Joseph Berger, and I'm joined for this Care Cues conversation with my patient, Michelle Biloon, who has had multiple sclerosis (MS) for the past 6 years. Hello, Michelle. Welcome.

Michelle Biloon: Thank you, Dr Berger.

Berger: Can you tell us a little bit about yourself, how you came to understand you had MS, and how you've done since the diagnosis was rendered?

Biloon: Yeah. It was a very short diagnosis period for me. In the winter of 2017, I started experiencing dizzy spells, and I didn't really know why. I eventually went to my primary care clinic where my doctor is, and they did blood work. Then, they did a CT and didn't see anything, and I just kind of kept feeling worse.

Then, finally, I went to an ENT just to see if it was maybe related to my ears. The ENT actually said, "You need to go to the ER and get an MRI." And while I was in the MRI, I could feel the dizzy spells. And I thought, Well, something is happening. I don't know what it is. And then a resident came in and said that they saw lesions on my brain, and they knew that it was going to be MS or something like it.

Berger: How did you feel about that?

Biloon: At the time, I was kind of glad to hear it was something. And I just asked her if, like, you die from it. That was the first thing I asked. It was like falling off a cliff.

It was making it hard for me to function in what I was doing, which was stand-up comedy, because of the cognitive issues I was having, the cognitive fog. That was how I ended up with you. Right away, you talked to me and were actually able to introduce to me some new medications that are out and are phenomenally better for MS plus were not pills or shots every day. It's made my MS over the years a lot more manageable.

Berger: I'd like to pick up on a couple of things you said.

Biloon: Sure.

Berger: One is, because most people envision MS as this terrible, crippling illness that's going to leave them wheelchair-bound, deprived of their profession, finding it difficult to stay in a marriage it's vested with what has been termed "lamentable results." And one of the first things that we as physicians have to do is to calm people down and say, "You know what. You have MS. You're going to be just fine. Trust me. We have wonderful medications for what you have, and we'll take care of it." In fact, I've made a habit of telling people quit worrying. You hired me to worry for you.

Biloon: Yep.

Berger: And I think that's helpful.

Biloon: I've been just so appreciative of that. There's a balance of being condescended to — do you know what I mean — and also being given information. I'm very sensitive to that balance because I consider myself an intelligent person. And you're being put in a position where someone knows more than you, and you have to listen.

Berger: One of the other challenges we face is getting somebody on a treatment. And we elected to put you on an intravenous therapy every 6 months.

Biloon: Especially because as a stand-up comedian, I was traveling a lot, doing these every-6-months infusion, especially with the high efficacy rate that it had been reported from what we had read and the low amount of side effects. I mean, just those things together was just something that seemed the easiest for me.

Berger: So did you encounter any challenges when we first got you started on the infusion therapy?

Biloon: The first infusion I got was at the hospital. But then after that, I had to go to the suburbs, to a center out there for the infusion. That was difficult because to get a ride out there and a ride back — it was a long trip for someone to wait with me. Taking an Uber is expensive, so was it for me to drive. You don't feel good for a couple of days after. So that was how it was, and I complained about it. Probably at every appointment we had, I complained about it.

Berger: Yeah. So some of the challenges you talked about are very, very common. As a physician on medications myself, I can tell you that I am not particularly compliant. And what I love about infusion therapies is that I know that the patient is getting their medicine. Because when they don't show up for a scheduled appointment, I'm called, and I know.

Biloon: I do have a bit of an allergic reaction to the drug. But that's been easily managed over time. Now, the drug infusions are actually being done at my home, which makes the whole process twice-a-year–world's better.

Berger: But there are other barriers that people confront other than the initiation of drugs. Had you encountered any?

Biloon: I think the problem that I had more so was finding the drugs that would manage some of my symptoms. It took a couple of years to sort of figure out what that would be, both with figuring them out and both dealing with insurance on certain medications.

Berger: That's one sort of problem that we confront. The other, of course, are those individuals who, for a variety of reasons, have difficulty with the diagnosis because of their backgrounds. And they may be sociocultural in nature. Every time you go to the physical therapist, it's some degree of money.

Now for some people, it's trivial. But for others, it's a considerable amount of money, relative to what it is that they earn. And you simply have to work within those confines as best you can.

We do have various programs that help people. So we try to employ them. There are, in addition to the sociocultural barriers, language barriers that we often confront. We, in our situation here in a large city, have a very large migrant population.

Fortunately, most of the people speak languages that either you speak as well, or there's somebody in the next room that speaks pretty well. But that's not always the case. So we do have an interpreter service that has to be employed.

Biloon: I cannot imagine the nuance in speaking to people from different ages and different backgrounds, who have different types of lifestyles, for them to understand.

Berger: I don't write at a computer. I think that really degrades the patient-physician relationship. What I do is I obtain a history. I do it on a piece of paper with a pen or a pencil.

I recapitulate them to the patient in paraphrasing it, to make sure that I have gotten it right and that they understand what I think I heard. That, I think, has been enormously helpful in helping people understand what may happen in the absence of treatment and why the treatment is important. That you can do, regardless of what the person's background is. So that's how I approach it.

Biloon: How do you deal with patients when they're not on the same page with you?

Berger: One important thing is that you have to be patient. That is something that it took me 50 years in medicine to learn. And then accepting the patient's opinion and saying, "All right, go home and think about it," because you often don't convince them when they're in the office with you.

Biloon: I did have a little bit of a cushion between my diagnosis and when we actually saw each other, where I was able to really sit in my thoughts on the different treatments and stuff. By the time that we were able to talk, it reassured me on that was the right plan.

Berger: I'm curious what your experience has been with our MS center.

Biloon: Through the portal, every time I need something, I'm usually reaching out, keeping you up-to-date on my primary care or whether it's trying to get a refill on one of my medications that I have to reach out. I really do feel that having that team there, being able to reach out, that's been extremely helpful to have and keeps me very secure because that's all I really need, especially during the pandemic, right? Because then I was very isolated and dealing with going through MS. So it was great to at least ­— and I did — shoot off emails or texts in the portal, and that's usually primarily how I communicated.

Berger: I will tell you, in my opinion, maybe nine out of 10 messages in the portal or calls that we get simply require reassurance.

Biloon: Yes.

Berger: You just either pick up the phone or shoot back a note, say, "This is not your MS. Don't worry about it." I mean, the most important thing for me is to keep people from worrying because that doesn't solve any problem.

Biloon: No, and it causes stress, which causes fatigue. I mean, it's a bad cycle.

Berger: In the past year, you've actually felt better, and you've gone back to performing. It sounds like the volume of performances has gotten back to what it was pre-illness. What do you see for the future?

Biloon: What I see is traveling more for stand-up and doing the sort of clubs and cities that I had kind of stopped doing from before I was diagnosed, so 2017 and prior to that. And then also even working on other things, writing and maybe even doing sort of books or one-person shows that even talk about sort of my struggles with MS and kind of coming back to where I am. I'm looking forward to the future, and I hope that that's the track I can keep going on.

Berger: I see no reason why you shouldn't.

Biloon: Thank you.

Berger: Michelle, thank you very much for joining me today in this conversation.

Biloon: Thank you so much for having me. It's been really wonderful to be able to sit down here with you.

Joseph R. Berger, MD: Hi. I'm Dr Joseph Berger, and I'm joined for this Care Cues conversation with my patient, Michelle Biloon, who has had multiple sclerosis (MS) for the past 6 years. Hello, Michelle. Welcome.

Michelle Biloon: Thank you, Dr Berger.

Berger: Can you tell us a little bit about yourself, how you came to understand you had MS, and how you've done since the diagnosis was rendered?

Biloon: Yeah. It was a very short diagnosis period for me. In the winter of 2017, I started experiencing dizzy spells, and I didn't really know why. I eventually went to my primary care clinic where my doctor is, and they did blood work. Then, they did a CT and didn't see anything, and I just kind of kept feeling worse.

Then, finally, I went to an ENT just to see if it was maybe related to my ears. The ENT actually said, "You need to go to the ER and get an MRI." And while I was in the MRI, I could feel the dizzy spells. And I thought, Well, something is happening. I don't know what it is. And then a resident came in and said that they saw lesions on my brain, and they knew that it was going to be MS or something like it.

Berger: How did you feel about that?

Biloon: At the time, I was kind of glad to hear it was something. And I just asked her if, like, you die from it. That was the first thing I asked. It was like falling off a cliff.

It was making it hard for me to function in what I was doing, which was stand-up comedy, because of the cognitive issues I was having, the cognitive fog. That was how I ended up with you. Right away, you talked to me and were actually able to introduce to me some new medications that are out and are phenomenally better for MS plus were not pills or shots every day. It's made my MS over the years a lot more manageable.

Berger: I'd like to pick up on a couple of things you said.

Biloon: Sure.

Berger: One is, because most people envision MS as this terrible, crippling illness that's going to leave them wheelchair-bound, deprived of their profession, finding it difficult to stay in a marriage it's vested with what has been termed "lamentable results." And one of the first things that we as physicians have to do is to calm people down and say, "You know what. You have MS. You're going to be just fine. Trust me. We have wonderful medications for what you have, and we'll take care of it." In fact, I've made a habit of telling people quit worrying. You hired me to worry for you.

Biloon: Yep.

Berger: And I think that's helpful.

Biloon: I've been just so appreciative of that. There's a balance of being condescended to — do you know what I mean — and also being given information. I'm very sensitive to that balance because I consider myself an intelligent person. And you're being put in a position where someone knows more than you, and you have to listen.

Berger: One of the other challenges we face is getting somebody on a treatment. And we elected to put you on an intravenous therapy every 6 months.

Biloon: Especially because as a stand-up comedian, I was traveling a lot, doing these every-6-months infusion, especially with the high efficacy rate that it had been reported from what we had read and the low amount of side effects. I mean, just those things together was just something that seemed the easiest for me.

Berger: So did you encounter any challenges when we first got you started on the infusion therapy?

Biloon: The first infusion I got was at the hospital. But then after that, I had to go to the suburbs, to a center out there for the infusion. That was difficult because to get a ride out there and a ride back — it was a long trip for someone to wait with me. Taking an Uber is expensive, so was it for me to drive. You don't feel good for a couple of days after. So that was how it was, and I complained about it. Probably at every appointment we had, I complained about it.

Berger: Yeah. So some of the challenges you talked about are very, very common. As a physician on medications myself, I can tell you that I am not particularly compliant. And what I love about infusion therapies is that I know that the patient is getting their medicine. Because when they don't show up for a scheduled appointment, I'm called, and I know.

Biloon: I do have a bit of an allergic reaction to the drug. But that's been easily managed over time. Now, the drug infusions are actually being done at my home, which makes the whole process twice-a-year–world's better.

Berger: But there are other barriers that people confront other than the initiation of drugs. Had you encountered any?

Biloon: I think the problem that I had more so was finding the drugs that would manage some of my symptoms. It took a couple of years to sort of figure out what that would be, both with figuring them out and both dealing with insurance on certain medications.

Berger: That's one sort of problem that we confront. The other, of course, are those individuals who, for a variety of reasons, have difficulty with the diagnosis because of their backgrounds. And they may be sociocultural in nature. Every time you go to the physical therapist, it's some degree of money.

Now for some people, it's trivial. But for others, it's a considerable amount of money, relative to what it is that they earn. And you simply have to work within those confines as best you can.

We do have various programs that help people. So we try to employ them. There are, in addition to the sociocultural barriers, language barriers that we often confront. We, in our situation here in a large city, have a very large migrant population.

Fortunately, most of the people speak languages that either you speak as well, or there's somebody in the next room that speaks pretty well. But that's not always the case. So we do have an interpreter service that has to be employed.

Biloon: I cannot imagine the nuance in speaking to people from different ages and different backgrounds, who have different types of lifestyles, for them to understand.

Berger: I don't write at a computer. I think that really degrades the patient-physician relationship. What I do is I obtain a history. I do it on a piece of paper with a pen or a pencil.

I recapitulate them to the patient in paraphrasing it, to make sure that I have gotten it right and that they understand what I think I heard. That, I think, has been enormously helpful in helping people understand what may happen in the absence of treatment and why the treatment is important. That you can do, regardless of what the person's background is. So that's how I approach it.

Biloon: How do you deal with patients when they're not on the same page with you?

Berger: One important thing is that you have to be patient. That is something that it took me 50 years in medicine to learn. And then accepting the patient's opinion and saying, "All right, go home and think about it," because you often don't convince them when they're in the office with you.

Biloon: I did have a little bit of a cushion between my diagnosis and when we actually saw each other, where I was able to really sit in my thoughts on the different treatments and stuff. By the time that we were able to talk, it reassured me on that was the right plan.

Berger: I'm curious what your experience has been with our MS center.

Biloon: Through the portal, every time I need something, I'm usually reaching out, keeping you up-to-date on my primary care or whether it's trying to get a refill on one of my medications that I have to reach out. I really do feel that having that team there, being able to reach out, that's been extremely helpful to have and keeps me very secure because that's all I really need, especially during the pandemic, right? Because then I was very isolated and dealing with going through MS. So it was great to at least ­— and I did — shoot off emails or texts in the portal, and that's usually primarily how I communicated.

Berger: I will tell you, in my opinion, maybe nine out of 10 messages in the portal or calls that we get simply require reassurance.

Biloon: Yes.

Berger: You just either pick up the phone or shoot back a note, say, "This is not your MS. Don't worry about it." I mean, the most important thing for me is to keep people from worrying because that doesn't solve any problem.

Biloon: No, and it causes stress, which causes fatigue. I mean, it's a bad cycle.

The risk of being hospitalized because of COVID-19 was reduced by 84% among people who used Paxlovid, reports a new study.

This medicine has been approved for use in the United States for people over 12 years old who are at risk of having a severe COVID-19 infection. 

The study was published in the Journal of Antimicrobial Chemotherapy.

Study authors examined the health records of almost 45,000 outpatients who tested positive for COVID-19 from January to August 2022. This sample period was when the Omicron strain was dominant.

The average patient age was 47. Sixty-two percent were White, 24% were Black, 6% were Hispanic, and 8% had an unknown ethnicity. A slight majority, 51%, had received two or more vaccine doses before the study period.

From the study group, 201 people were hospitalized within 28 days of their positive COVID test.

Almost 5,000 people in the study group received Paxlovid. The use of Paxlovid was the best indicator of avoiding hospitalization, with three of those people being hospitalized.

“Patients who were treated with Paxlovid were twice as likely to have received at least two doses of COVID-19 vaccine,” the University of Minnesota’s CIDRAP reported. “They were also more likely to be 70 years or older.”

People taking Paxlovid were more likely to be White and to live in middle- or upper-income areas.

“COVID-19 hospitalization risk was reduced by 84% among [Paxlovid] recipients in a large, diverse healthcare system during the Omicron wave,” the study’s authors wrote. “These results suggest that [Paxlovid] remained highly effective in a setting substantially different than the original clinical trials.”

TOPLINE:

Intermittent hypoxemia prompted higher postprandial plasma triglyceride levels in men than in women compared with normoxia.

METHODOLOGY:

• Potential gender differences in the impact of intermittent hypoxemia on triglycerides have not been well studied, despite the increased risk for metabolic comorbidities in obstructive sleep apnea (OSA).
• The researchers recruited 24 healthy young adults with a mean age of 23.3 years for the 12 men and 21.3 years for the 12 women.
• Participants consumed a high-fat meal followed by 6 hours of exposure to intermittent hypoxemia or ambient air; the primary outcome was changes in postprandial plasma triglyceride levels.

TAKEAWAY:

• Intermittent hypoxemia was associated with significantly higher postprandial triglycerides in men but not in women.
• Women had lower levels of total triglycerides as well as denser triglyceride-rich lipoprotein triglycerides (TRL-TG) and buoyant TRL-TG in both normoxia and hypoxemia conditions compared with men.
• Glucose levels were significantly higher in men and significantly lower in women during intermittent hypoxemia compared with normoxia (P < .001 for both sexes).

IN PRACTICE:

“Although there is a need for larger confirmatory studies in individuals living with obstructive sleep apnea, this study demonstrates that intermittent hypoxemia alters triglyceride metabolism differently between men and women,” the researchers wrote.

SOURCE:

The lead author of the study was Nicholas Goulet, MD, of the University of Ottawa, Ottawa, Ontario, Canada. The study was published online in The Journal of Physiology on January 29, 2024.

LIMITATIONS:

Limitations of the study included the experimental design with simulated OSA, the small and homogeneous study population, the use of a specific profile for intermittent hypoxemia, and the use of a specific high-fat meal.

DISCLOSURES:

The study was supported by the Natural Sciences and Engineering Research Council of Canada and the Association Médicale Universitaire de l’Hôpital Montfort. The researchers had no financial conflicts to disclose.

The results of a large longitudinal study spanning several years support a decrease in the risk for dementia among older adults who regularly use the Internet for < 2 hours per day. 

Several cross-sectional and longitudinal studies (though with relatively short follow-up periods) suggest that regular Internet use helps maintain cognitive reserve, although some observers have voiced skepticism. This hypothesis is particularly relevant for older patients facing the potentially detrimental effects of brain aging. According to some studies, memory, cognitive performance, and verbal reasoning tend to be better preserved among Internet users.

Several factors come into play, including socioeconomic disparities, socio-educational level, and generational differences, since Internet usage varies qualitatively and quantitatively with age. Older patients theoretically have more limited Internet usage. Under these conditions, the effect on cognitive functions would likely be modest compared with generations who were immersed in digital technology early on and tend to overuse it. After a certain age, accelerated brain aging would weigh much more heavily than any potential positive effects of the Internet. It is worth noting that the negative effects of Internet use have mainly been studied in young subjects, thus there is a lack of data concerning older patients.

Nearly 20,000 Participants

These considerations highlight the significance of a longitudinal cohort study that included 18,154 adults aged 50-64.9 years who were free from any dementia at baseline. These adults were participating in the Health and Retirement Study. The median follow-up period was 7.9 years, and follow-up extended to 17.1 years in some cases. Given that adults with better cognitive health are likely to self-select as regular users, the propensity score method was employed to control for this nonrandom factor using inverse probability weighting.

The risk for dementia based on initial Internet use was estimated using the Cox proportional hazards model, incorporating potentially late entry into the workforce and several covariables. Interactions with education level, gender, generation, and ethnic origin were also considered. Cumulative Internet exposure in terms of regular periodic use throughout life was included in the statistical analysis, as well as the hours spent on this activity each day. The analyses were conducted from September 2021 to November 2022.

Risk Nearly Halved

Regular Internet use was associated with a reduced risk for dementia, compared with irregular use. The hazard ratio (HR) for dementia was estimated at 0.57. After adjustment for the nonrandom factor of self-selection, this association persisted, and the HR decreased to 0.54. Accounting for baseline cognitive decline did not substantially change these results and yielded an HR of 0.62. The difference in risk between regular and irregular users was not altered by considering potential confounding factors such as education level, ethnic origin, gender, or generation. The longer the cumulative exposure over life, the lower the risk for dementia during follow-up.

The relationship between dementia risk and daily Internet usage hours seems to follow a U-shaped curve, with the lowest risk observed for durations between 0.1 and 2 hours. However, these estimates did not reach statistical significance because of the small sample size analyzed.

The risk for dementia appears to be approximately twice as low among regular Internet users compared with nonusers. This hypothesis deserves serious consideration because of the large sample size and long follow-up duration, as well as careful consideration of as many potential confounding factors as possible. Potential negative effects remain to be clarified as the study was not designed to detect them. The results of previous studies suggest that Internet usage should be moderate for optimal benefit, with approximately 2 hours per day being the most suitable duration, regardless of age, until proven otherwise.

The results of a large longitudinal study spanning several years support a decrease in the risk for dementia among older adults who regularly use the Internet for < 2 hours per day. 

Several cross-sectional and longitudinal studies (though with relatively short follow-up periods) suggest that regular Internet use helps maintain cognitive reserve, although some observers have voiced skepticism. This hypothesis is particularly relevant for older patients facing the potentially detrimental effects of brain aging. According to some studies, memory, cognitive performance, and verbal reasoning tend to be better preserved among Internet users.

TOPLINE:

Eosinopenia and low ratio between eosinophil count (EC) and neutrophil count (NC) are potential indicators of infection for patients with inflammatory disease who are treated with tocilizumab.

METHODOLOGY:

• The researchers reviewed data from 163 patients treated for an inflammatory disease (mostly rheumatoid arthritis) with tocilizumab at a single center between 2009 and 2020.
• The study population included 41 patients with unscheduled hospitalizations for suspected infections. Patients’ median age was 59 years, and 83% were female.
• The researchers assessed the association in tocilizumab-treated patients between infections and eosinopenia (defined as EC < 0.05 g/L) and a low ratio between EC and NC, defined as EC/NC × 1000 < 11.8.

TAKEAWAY:

• Infectious diseases were diagnosed in 20 of the hospitalized patients (49%); the most common diseases were pneumonia (30%), joint or bone infections (25%), and gastrointestinal tract infections (15%).
• The median absolute EC at hospital admission was significantly lower for patients with infections than for those without infections (0.06 g/L vs 0.20 g/L).
• The median EC/NC × 1000 ratios were significantly lower in infected patients vs noninfected patients (6.54 vs 48.50).
• No differences appeared between patients with and without infections in age, sex, type of inflammatory disease, and steroid treatment.

IN PRACTICE:

“This original study suggests that all those easily available parameters should be used to maximize [sensitivity] in the screening of infection in patients undergoing treatment with IL-6 pathway antagonists,” the researchers wrote.

SOURCE:

The lead author on the study was Audrey Glatre, MD, of University Hospital Centre Reims, France. The study was published online in RMD Open on February 9.

LIMITATIONS:

The retrospective, observational design; relatively small study population; and use of data from a single center were potential limitations of the findings.

DISCLOSURES:

The study received no outside funding. The researchers had no financial conflicts to disclose.

For the first time, methamphetamines and cocaine have overtaken heroin and prescription opioids in illicit drug use involving fentanyl nationwide and in nearly every state, a new report suggested.

The use of methamphetamine among people who also use fentanyl reached a record high in 2023, urinary drug tests (UDTs) showed, while the use of prescription opioids in that same group reached an historic low. 

Investigators said the data offer further evidence that the US is experiencing a predicted “fourth wave” of the opioid crisis.

The report came on the heels of new data from the Centers for Disease Control and Prevention (CDC) that showed the preferred method of fentanyl-related illicit drug use shifted from intravenous injection to smoking.

“The rise in cocaine and methamphetamine nationally does not seem to be driven by one or even a few regions of the country,” authors of the 2024 Health Signals Report wrote. “Stimulants are a serious national challenge emphasizing the need for continued progress on the national plan to address methamphetamine supply, use, and consequences.”

The report, published online on February 22 by San Diego–based drug testing lab Millennium Health, is an analysis of urine specimens from 4.1 million unique patients aged ≥ 18 years, collected in all 50 states from 2013 to 2023. 
 

A Year of Firsts

Last year, 60% of specimens that contained fentanyl also contained methamphetamine, an increase of 875% since 2015, according to Millennium’s report. It’s the first time that methamphetamine and cocaine were detected more often in urine drug tests than heroin and prescription opioids.

About a quarter of fentanyl-positive specimens also contained cocaine, 17% heroin and just 7% prescription opioids.

Almost all the fentanyl-positive specimens were positive for at least one additional substance; almost half contained three or more. Xylazine, an animal sedative known as “tranq,” was detected in nearly 14% of fentanyl-positive specimens.

“These combinations increase overdose vulnerability and may lessen responses to overdose reversal agents, making treatment as challenging as any time in history,” Millennium Senior VP and Chief Clinical Officer, Angela G. Huskey, PharmD, CPE, said in a statement.

The Millennium data back up what has been increasingly reported by the CDC and others. As reported in September by this news organization, in 2010, stimulants were co-involved in less than 1% of fentanyl overdose deaths. By 2021, stimulant-fentanyl use accounted for 32% of all fatal fentanyl overdoses.

In July 2023, the CDC reported a significant spike in overdose deaths involving cocaine or other psychostimulants and opioids from 2011 to 2021. In 2021, 79% of overdose deaths involving cocaine also involved an opioid and 66% of overdose deaths involving psychostimulants also involved an opioid, according to the CDC.

There were more overdose deaths from stimulants combined with opioids than from opioids alone in 2022, according to the CDC’s State Unintentional Drug Overdose Reporting System, which includes reports from 30 jurisdictions.
 

Smoking Overtakes Injection

The route of administration for opioids and stimulants — whether used alone or in combination, has also changed, the CDC recently reported. In 2022, just 16% of overdose deaths involved injection drug use, down from 23% in 2020, according to the analysis, which included data from 28 jurisdictions. For deaths involving illegally manufactured fentanyl, just 12% of deaths involved IV drug use.

By 2022, “smoking was the most commonly documented route of use in overdose deaths,” CDC researchers wrote in their report. Almost a quarter of deaths that year involved smoking.

The increase in smoking was seen for all substances, including opioids, fentanyl and combinations of fentanyl and stimulants, reported the agency.

Users might be switching to smoking from injections because there is a perception of fewer adverse health effects such as abscesses, reduced cost and stigma, sense of more control over quantity consumed per use, and “a perception of reduced overdose risk,” the researchers wrote.

Smoking still “carries substantial overdose risk because of rapid drug absorption,” they added.

Some harm reduction programs are adapting to the change in use patterns by providing safer smoking supplies and by changing messaging to warn of the dangers associated with smoking drugs, the CDC report noted.

Severe, refractory, and fibrostenotic eosinophilic esophagitis (EoE) responded well in the everyday clinical setting to the monoclonal antibody dupilumab (Dupixent). Most patients achieved histologic, endoscopic, and symptom improvement with a median of 6 months’ treatment with the interleukin 4 and 13 blocker, and esophageal stricture diameter improved as well, according to a single-center retrospective study in Clinical Gastroenterology and Hepatology.

“Dupilumab has real-world efficacy for a severe EoE population, most of whom would not have qualified for prior clinical trials,” concluded gastroenterologists Christopher J. Lee, MD (lead author), and Evan S. Dellon, MD, MPH, AGAF, of the Center for Esophageal Diseases and Swallowing, at the University of North Carolina School of Medicine in Chapel Hill.

These real-world findings aligned with data from the group’s phase 3 clinical trial.

In addition, several case reports or series have highlighted the real-world efficacy of dupilumab, with a particular focus on pediatric patients and those with other atopic diseases.

“Despite nonresponse to prior treatments, these patients can likely expect to see results similar to what was seen in the clinical trial,” Dr. Dellon said in an interview. “However, it would be good to have similar confirmatory data from other centers, and I’m sure those data will be forthcoming as more EoE patients are treated with dupilumab.”

The study

The investigators identified 46 patients treated with dupilumab for refractory fibrostenotic EoE at the university’s medical center. All had failed or lost response to one or more standard therapies such as proton pump inhibitors, topical glucocorticosteroids, and a food elimination diet.

Previous treatments also included systemic steroids, cromolyn, ketotifen, montelukast, and 6-mercaptopurine, all with minimal response. Some 85% of patients had undergone an average of 9.0+ 7.0 pre-dupilumab dilations.

The biologic was initially prescribed off-label before FDA approval. Patients received it at a dose of 300 mg subcutaneously either fortnightly (n = 16) or weekly (n = 30), depending on insurance approval and timing of prescription. Length of treatment varied based on the time from prescription to first post-treatment evaluative endoscopy.

Patients showed endoscopic, histologic, and symptomatic improvement on dupilumab compared with both the worst and the pre-dupilumab esophagogastroduodenoscopies.

Among the specific findings:

• Peak eosinophil counts significantly decreased.
• Post-dupilumab histologic response rates were 80% and 57% for fewer than 15 eosinophils per high-power field, and 6 or fewer eosinophils per high-power field, respectively.
• The Endoscopic Reference Score decreased from 5.01 to 1.89 (P < .001 for all).
• Pre-dilation esophageal diameter increased from 13.9 to 16.0 mm (P < .001), although the proportion of strictures was stable.
• Global symptom improvement was reported in 91% of patients (P < .001).

Commenting on the study but not involved in it, David A. Katzka, MD, professor of medicine at Columbia University in New York City, said the findings would be of immediate use to practicing gastroenterologists.

“It’s necessary to do clinical trials, but real-world data make the clinician feel more comfortable in prescribing. Interestingly, I am seeing dupilumab being recommended not just for refractory disease but also as first-line therapy,” he said.

Dr. Dellon noted that the incidence and prevalence of EoE are rising rapidly in the US and around the world. “This increase is outpacing growing recognition of the disease,” he said. “Most likely, environmental factors are driving this change.” He called for studies to determine the long-term efficacy of dupilumab for this severe subgroup — and the potential benefit of moving dupilumab earlier into the treatment algorithm.

The latter is a controversial question, noted Dr. Katzka. “For patients with other indications such as asthma or eczema, dupilumab is the ideal medication,” he said. And it can be a first-line therapy if there are contraindications to alternatives or if compliance will be better with a once-weekly injection as opposed to a twice-daily medication or a food elimination diet. But overall, our more established therapies should be considered first.”

Dr. Katzka emphasized the need to further define EoE phenotypes in order to personalize therapy. “There’s likely a group of patients who should go straight to dupilumab, perhaps those marked by factors such as severity, progression, young age, or other atopic disorders. But we have yet to definitively identify this group.”

Severe, refractory, and fibrostenotic eosinophilic esophagitis (EoE) responded well in the everyday clinical setting to the monoclonal antibody dupilumab (Dupixent). Most patients achieved histologic, endoscopic, and symptom improvement with a median of 6 months’ treatment with the interleukin 4 and 13 blocker, and esophageal stricture diameter improved as well, according to a single-center retrospective study in Clinical Gastroenterology and Hepatology.

“Dupilumab has real-world efficacy for a severe EoE population, most of whom would not have qualified for prior clinical trials,” concluded gastroenterologists Christopher J. Lee, MD (lead author), and Evan S. Dellon, MD, MPH, AGAF, of the Center for Esophageal Diseases and Swallowing, at the University of North Carolina School of Medicine in Chapel Hill.

These real-world findings aligned with data from the group’s phase 3 clinical trial.

In addition, several case reports or series have highlighted the real-world efficacy of dupilumab, with a particular focus on pediatric patients and those with other atopic diseases.

“Despite nonresponse to prior treatments, these patients can likely expect to see results similar to what was seen in the clinical trial,” Dr. Dellon said in an interview. “However, it would be good to have similar confirmatory data from other centers, and I’m sure those data will be forthcoming as more EoE patients are treated with dupilumab.”

The study

The investigators identified 46 patients treated with dupilumab for refractory fibrostenotic EoE at the university’s medical center. All had failed or lost response to one or more standard therapies such as proton pump inhibitors, topical glucocorticosteroids, and a food elimination diet.

Previous treatments also included systemic steroids, cromolyn, ketotifen, montelukast, and 6-mercaptopurine, all with minimal response. Some 85% of patients had undergone an average of 9.0+ 7.0 pre-dupilumab dilations.

The biologic was initially prescribed off-label before FDA approval. Patients received it at a dose of 300 mg subcutaneously either fortnightly (n = 16) or weekly (n = 30), depending on insurance approval and timing of prescription. Length of treatment varied based on the time from prescription to first post-treatment evaluative endoscopy.

Patients showed endoscopic, histologic, and symptomatic improvement on dupilumab compared with both the worst and the pre-dupilumab esophagogastroduodenoscopies.

Among the specific findings:

• Peak eosinophil counts significantly decreased.
• Post-dupilumab histologic response rates were 80% and 57% for fewer than 15 eosinophils per high-power field, and 6 or fewer eosinophils per high-power field, respectively.
• The Endoscopic Reference Score decreased from 5.01 to 1.89 (P < .001 for all).
• Pre-dilation esophageal diameter increased from 13.9 to 16.0 mm (P < .001), although the proportion of strictures was stable.
• Global symptom improvement was reported in 91% of patients (P < .001).

Commenting on the study but not involved in it, David A. Katzka, MD, professor of medicine at Columbia University in New York City, said the findings would be of immediate use to practicing gastroenterologists.

“It’s necessary to do clinical trials, but real-world data make the clinician feel more comfortable in prescribing. Interestingly, I am seeing dupilumab being recommended not just for refractory disease but also as first-line therapy,” he said.

Dr. Dellon noted that the incidence and prevalence of EoE are rising rapidly in the US and around the world. “This increase is outpacing growing recognition of the disease,” he said. “Most likely, environmental factors are driving this change.” He called for studies to determine the long-term efficacy of dupilumab for this severe subgroup — and the potential benefit of moving dupilumab earlier into the treatment algorithm.

The latter is a controversial question, noted Dr. Katzka. “For patients with other indications such as asthma or eczema, dupilumab is the ideal medication,” he said. And it can be a first-line therapy if there are contraindications to alternatives or if compliance will be better with a once-weekly injection as opposed to a twice-daily medication or a food elimination diet. But overall, our more established therapies should be considered first.”

Dr. Katzka emphasized the need to further define EoE phenotypes in order to personalize therapy. “There’s likely a group of patients who should go straight to dupilumab, perhaps those marked by factors such as severity, progression, young age, or other atopic disorders. But we have yet to definitively identify this group.”

TOPLINE:

Radiation exposure to the pulmonary veins during radiotherapy (RT) for non–small cell lung cancer (NSCLC) raises the risk for atrial fibrillation (AF), according to new findings.

METHODOLOGY:

• Arrhythmia — with AF being the most common type — affects roughly 11% of patients following lung cancer RT.
• Given RT’s recognized impact on cardiac tissues over time, researchers hypothesized that the dosage affecting pulmonary veins might contribute to the observed increased rates of AF after RT.
• To investigate, researchers looked back at 420 patients with NSCLC (52% women, median age 70) undergoing definitive RT (± chemo) with modern planning techniques at 55 Gy in 20 once-daily fractions over 4 weeks.
• Most patients underwent treatment planning using volumetric modulated arc therapy (50%) or static gantry intensity-modulated RT (20%). Chemotherapy was administered in a minority of cases (33%).
• Pulmonary veins were contoured on planning CT scans, and dose metrics were calculated. The association between pulmonary veins dose and incidence of new AF was evaluated, with AF verified by a cardiologist.

TAKEAWAY:

• Out of the entire cohort, 26 patients (6%) developed AF a median of 13 months after treatment. All cases of AF were grade 3 except for two grade 4 events.
• Radiation dose to the left and right pulmonary veins was significantly associated with incident AF. Dose volumes most strongly associated with AF were ≥ 55 Gy (V55) on the left and ≥ 10 Gy (V10) on the right.
• The risk for AF increased by 2% per percentage point increase in the left pulmonary veins V55 and 1% in the right pulmonary veins V10. The associations were statistically significant after accounting for cardiovascular factors and risk for death risk.
• The area under the curve for prediction of AF events was 0.64 (P = .02) for the left pulmonary veins V55 and 0.61 (P = .03) for the right pulmonary veins V10. The optimal thresholds for predicting AF were 2% and 54%, respectively.

IN PRACTICE:

“The implications of these data are that actively sparing these structures could reduce the incidence of [AF], and where this is not possible, patients identified as being at high risk of AF could undergo active screening during follow-up,” the researchers said, adding that further validation of these findings should take place before implementation.

SOURCE:

The study, with first author Gerard M. Walls, MB, MRCP, Patrick G Johnston Centre for Cancer Research, Queen’s University Belfast, Belfast, Northern Ireland, was published online on January 4 in Radiotherapy and Oncology .

LIMITATIONS:

This was a single-center, retrospective study with a small number of AF events. The study may have underestimated the relationship between pulmonary vein irradiation and new AF events. The findings needed validation in larger datasets.

DISCLOSURES:

The study had no commercial funding. The authors declared no conflicts of interest.
