Using anti-inflammatory drugs may prolong back pain

Article Type
Changed
Thu, 12/15/2022 - 15:38

A new study questions the conventional wisdom of using steroids and anti-inflammatory drugs like ibuprofen to treat low back pain if exercise and other nondrug therapies don’t work right away.

Those medications offer relief from acute pain but may actually increase a person’s chances of developing chronic pain, said the investigators for a study published in Science Translational Medicine. The study results indicate that inflammation is a normal part of recovering from a painful injury and that inhibiting inflammation may result in more-difficult-to-treat chronic pain.

“For many decades it’s been standard medical practice to treat pain with anti-inflammatory drugs,” Jeffrey Mogil, PhD, a psychology professor at McGill University, Montreal, said in a school news release. “But we found that this short-term fix could lead to longer-term problems.”

Researchers looked at low back pain because it’s so common, with 25% of U.S. adults saying they had low back pain in the previous 3 months, according to the Centers for Disease Control and Prevention. Acute back pain is defined as lasting less than 4 weeks while chronic back pain lasts more than 12 weeks.

By examining blood samples, researchers discovered that people whose low back pain was resolved had high inflammation driven by neutrophils, a type of white blood cell that helps the body fight infection, the study said.

“Neutrophils dominate the early stages of inflammation and set the stage for repair of tissue damage. Inflammation occurs for a reason, and it looks like it’s dangerous to interfere with it,” Dr. Mogil said in the news release.

The research team found that blocking neutrophils in mice prolonged pain in the animals up to 10-fold. Pain also was prolonged when the mice were given anti-inflammatory drugs and steroids, the news release says.

McGill University said other studies support the findings. The school cited an analysis of 500,000 people in the United Kingdom. The analysis found that those taking anti-inflammatory drugs for pain were more likely to have pain 2 to 10 years later.

While saying the study suggests it’s time to reconsider how pain is treated, the researchers called for clinical trials on humans, not just observations of people with low back pain.

Experts warned about accepting the results without further investigation.

“It’s intriguing but requires further study,” Steven J. Atlas, MD, director of the Primary Care Research & Quality Improvement Network at Massachusetts General Hospital, Boston, told The New York Times.

FDA approves oral form of ALS drug edaravone

Article Type
Changed
Tue, 06/07/2022 - 11:18

The Food and Drug Administration has approved an orally administered version of edaravone (Radicava ORS, Mitsubishi Tanabe Pharma America) for adults with amyotrophic lateral sclerosis (ALS). Edaravone is a pyrazolone free-radical scavenger thought to lessen the effects of oxidative stress, which is a probable factor in ALS onset and progression. The drug was first approved in 2017 as an intravenous (IV) infusion to treat ALS.

Radicava ORS is self-administered and can be taken at home. After fasting overnight, Radicava ORS should be taken in the morning orally or through a feeding tube. The oral version has the same dosing regimen as the original IV version, with an initial treatment cycle of daily dosing for 14 days, followed by a 14-day drug-free period and subsequent treatment cycles consisting of daily dosing for 10 out of 14-day periods, followed by 14-day drug-free periods.

Compared with the IV formation of Radicava, Radicava ORS has been shown to generate comparable levels of active drug in the bloodstream, the FDA said.

The FDA determined that IV Radicava was effective based on a 6-month clinical trial in Japan involving 137 individuals who were randomly chosen to receive either the drug or a placebo. At 24 weeks, individuals receiving Radicava showed less decline on a clinical assessment of daily functioning, compared with those receiving placebo.

The most common side effects of Radicava are bruising, problems walking, and headache. Fatigue is also a possible side effect from Radicava ORS. Both formulations can have serious side effects associated with allergic reactions, including hives, rash, and shortness of breath.

Full prescribing information, including additional information on risks associated with Radicava ORS, is available online.

The FDA granted Radicava ORS orphan drug status, priority review, and Fast Track designations.

Myositis guidelines aim to standardize adult and pediatric care

Article Type
Changed
Thu, 12/29/2022 - 07:31

All patients with idiopathic inflammatory myopathies (IIM) should be screened for swallowing difficulties, according to the first evidence-based guideline to be produced.

The guideline, which has been developed by a working group of the British Society for Rheumatology (BSR), also advises that all diagnosed patients should have their myositis antibody levels checked and have their overall well-being assessed. Other recommendations for all patients include the use of glucocorticoids to reduce muscle inflammation and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) for long-term treatment.

“Finally, now, we’re able to standardize the way we treat adults and children with IIM,” senior guideline author Hector Chinoy, PhD, said at the society’s annual meeting.

It has been a long labor of love, however, taking 4 years to get the guideline published, said Dr. Chinoy, professor of rheumatology and neuromuscular disease at the University of Manchester (England), and a consultant at Salford (England) Royal Hospital.

“We’re not covering diagnosis, classification, or the investigation of suspected IIM,” said Dr. Chinoy. Inclusion body myositis also is not included.

Altogether, there are 13 recommendations that have been developed using a PICO (patient or population, intervention, comparison, outcome) format, graded based on the quality of the available evidence, and then voted on by the working group members to give a score of the strength of agreement. Dr. Chinoy noted that there was a checklist included in the Supplementary Data section of the guideline to help follow the recommendations.

“The target audience for the guideline reflects the variety of clinicians caring for patients with IIM,” Dr. Chinoy said. So that is not just pediatric and adult rheumatologists, but also neurologists, dermatologists, respiratory physicians, oncologists, gastroenterologists, cardiologists, and of course other health care professionals. This includes rheumatology and neurology nurses, psychologists, speech and language therapists, and podiatrists, as well as rheumatology specialist pharmacists, physiotherapists, and occupational therapists.

With reference to the latter, Liza McCann, MBBS, who co-led the development of the guideline, said in a statement released by the BSR that the guideline “highlights the importance of exercise, led and monitored by specialist physiotherapists and occupational therapists.”

Dr. McCann, a consultant pediatric rheumatologist at Alder Hey Hospital, Liverpool, England, and Honorary Clinical Lecturer at the University of Liverpool, added that the guidelines also cover “the need to address psychological wellbeing as an integral part of treatment, in parallel with pharmacological therapies.”

Recommendation highlights

Some of the highlights of the recommendations include the use of high-dose glucocorticoids to manage skeletal muscle inflammation at the time of treatment induction, with specific guidance on the different doses to use in adults and in children. There also is guidance on the use of csDMARDs in both populations and what to use if there is refractory disease – with the strongest evidence supporting the use of intravenous immunoglobulin (IVIG) or cyclophosphamide, and possibly rituximab and abatacept.

“There is insufficient evidence to recommend JAK inhibition,” Dr. Chinoy said. The data search used to develop the guideline had a cutoff of October 2020, but even now there is only anecdotal evidence from case studies, he added.

Importantly, the guidelines recognize that childhood IIM differs from adult disease and call for children to be managed by pediatric specialists.

“Routine assessment of dysphagia should be considered in all patients,” Dr. Chinoy said, “so ask the question.” The recommendation is that a swallowing assessment should involve a speech and language therapist or gastroenterologist, and that IVIG be considered for active disease and dysphagia that is resistant to other treatments.

There also are recommendations to screen adult patients for interstitial lung disease, consider fracture risk, and screen adult patients for cancer if they have specific risk factors that include older age at onset, male gender, dysphagia, and rapid disease onset, among others.
 

 

 

Separate cancer screening guidelines on cards

“Around one in four patients with myositis will develop cancer within the 3 years either before or after myositis onset,” Alexander Oldroyd, MBChB, PhD, said in a separate presentation at the BSR annual meeting.

“It’s a hugely increased risk compared to the general population, and a great worry for patients,” he added. Exactly why there is an increased risk is not known, but “there’s a big link between the biological onset of cancer and myositis.”

Dr. Oldroyd, who is an NIHR Academic Clinical Lecturer at the University of Manchester in England and a coauthor of the BSR myositis guideline, is part of a special interest group set up by the International Myositis Assessment and Clinical Studies Group (IMACS) that is in the process of developing separate guidelines for cancer screening in people newly diagnosed with IIM.

The aim was to produce evidence-based recommendations that were both “pragmatic and practical,” that could help clinicians answer patient’s questions on their risk and how best and how often to screen them, Dr. Oldroyd explained. Importantly, IMACS has endeavored to create recommendations that should be applicable across different countries and health care systems.

“We had to acknowledge that there’s not a lot of evidence base there,” Dr. Oldroyd said, noting that he and colleagues conducted a systematic literature review and meta-analysis and used a Delphi process to draft 20 recommendations. These cover identifying risk factors for cancer in people with myositis and categorizing people into low, medium, and high-risk categories. The recommendations also cover what should constitute basic and enhanced screening, and how often someone should be screened.

Moreover, the authors make recommendations on the use of imaging modalities such as PET and CT scans, as well as upper and lower gastrointestinal endoscopy and naso-endoscopy.

“As rheumatologists, we don’t talk about cancer a lot,” Dr. Oldroyd said. “We pick up a lot of incidental cancers, but we don’t usually talk about cancer screening with patients.” That’s something that needs to change, he said.

“It’s important – just get it out in the open, talk to people about it,” Dr. Oldroyd said.

“Tell them what you’re wanting to do, how you’re wanting to investigate for it, clearly communicate their risk,” he said. “But also acknowledge the limited evidence as well, and clearly communicate the results.”

Dr. Chinoy acknowledged he had received fees for presentations (UCB, Biogen), consultancy (Alexion, Novartis, Eli Lilly, Orphazyme, AstraZeneca), or grant support (Eli Lilly, UCB) that had been paid via his institution for the purpose of furthering myositis research. Dr. Oldroyd had no conflicts of interest to disclose.

The aim was to produce evidence-based recommendations that were both “pragmatic and practical,” that could help clinicians answer patient’s questions on their risk and how best and how often to screen them, Dr. Oldroyd explained. Importantly, IMACS has endeavored to create recommendations that should be applicable across different countries and health care systems.

“We had to acknowledge that there’s not a lot of evidence base there,” Dr. Oldroyd said, noting that he and colleagues conducted a systematic literature review and meta-analysis and used a Delphi process to draft 20 recommendations. These cover identifying risk factors for cancer in people with myositis and categorizing people into low, medium, and high-risk categories. The recommendations also cover what should constitute basic and enhanced screening, and how often someone should be screened.

Moreover, the authors make recommendations on the use of imaging modalities such as PET and CT scans, as well as upper and lower gastrointestinal endoscopy and naso-endoscopy.

“As rheumatologists, we don’t talk about cancer a lot,” Dr. Oldroyd said. “We pick up a lot of incidental cancers, but we don’t usually talk about cancer screening with patients.” That’s something that needs to change, he said.

“It’s important – just get it out in the open, talk to people about it,” Dr. Oldroyd said.

“Tell them what you’re wanting to do, how you’re wanting to investigate for it, clearly communicate their risk,” he said. “But also acknowledge the limited evidence as well, and clearly communicate the results.”

Dr. Chinoy acknowledged he had received fees for presentations (UCB, Biogen), consultancy (Alexion, Novartis, Eli Lilly, Orphazyme, AstraZeneca), or grant support (Eli Lilly, UCB) that had been paid via his institution for the purpose of furthering myositis research. Dr. Oldroyd had no conflicts of interest to disclose.

Exenatide linked to less hyperglycemia after stroke

Article Type
Changed
Thu, 12/15/2022 - 14:32

Treatment with the diabetes drug exenatide was associated with a significant decrease in hyperglycemia in acute stroke patients, a new study shows.

The research could offer clinicians an alternative to insulin therapy to treat hyperglycemia and reduce glucose levels, which are elevated in up to 60% of stroke patients and associated with worse outcomes after stroke.

“Use of these diabetes drugs to control glucose in acute stroke has enormous potential,” said lead researcher Christopher Bladin, PhD, professor of neurology at Monash University and Eastern Health Clinical School, Australia.

The findings were presented at the European Stroke Organisation Conference (ESOC) 2022 annual meeting in Lyon, France.
 

A better fix than insulin?

Hyperglycemia is common in stroke patients, including those who have no prior history of diabetes. Among stroke patients with normal blood glucose upon admission, about 30% will develop hyperglycemia within 48 hours of stroke onset.

Previous research suggests that hyperglycemia is a poor prognostic factor in patients with stroke and may reduce the efficacy of reperfusion therapies such as thrombolysis and mechanical thrombectomy.

“We’ve been looking for different ways of treating hyperglycemia for quite some time, and one of the obvious ways is to use insulin therapy,” Dr. Bladin said. “But as we’ve seen from multiple studies, insulin therapy is difficult.”

Insulin treatment is resource-heavy, significantly increases the risk for hypoglycemia, and some studies suggest the therapy isn’t associated with better outcomes.

An advantage to a GLP-1 agonist-like exenatide, Dr. Bladin added, is that it’s glucose-dependent. As the glucose level falls, the drug’s efficacy diminishes. It is delivered via an autoinjector and easy to administer.

A case for more study

To study exenatide’s efficacy in reducing hyperglycemia and improving neurologic outcomes, researchers developed the phase 2, international, multicenter, randomized controlled TEXAIS trial.

The study enrolled 350 patients following an ischemic stroke. Within 9 hours of stroke onset, patients received either standard care or a subcutaneous injection of 5 mg of exenatide twice daily for 5 days.

On admission, 42% of patients had hyperglycemia, defined as blood glucose > 7.0 mmol/L.

The study’s primary outcome was at least an 8-point improvement in National Institutes of Health Stroke Scale (NIHSS) score by 7 days after treatment with exenatide. Although there was a trend toward better scores with exenatide, the score was not significantly different between groups (56.7% with standard care versus 61.2% with exenatide; adjusted odds ratio, 1.22; P = .38).

However, when the researchers examined hyperglycemia frequency, they found significantly lower incidence in patients treated with exenatide (P = .002).

There were no cases of hypoglycemia in either group, and only 4% of the study group reported nausea or vomiting.

“Clearly exenatide is having some benefit in terms of keeping glucose under control, reducing hyperglycemia,” Dr. Bladin said. “It certainly lends itself to a larger phase 3 study which can look at this more completely.”
 

Value to clinicians

Commenting on the findings, Yvonne Chun, PhD, honorary senior clinical lecturer at University of Edinburgh, noted that, even though the study didn’t find a significant association with improved neurological outcomes, the reduced risk for hypoglycemia makes exenatide an attractive alternative to insulin therapy in stroke patients.

“The results are of value to clinicians, as exenatide could potentially be a safer medication to administer than an insulin infusion in acute stroke patients with hyperglycemia,” Dr. Chun said. “There is less risk of hypoglycemia with exenatide compared to standard care.”

However, Dr. Chun noted that more study is needed before exenatide can replace standard care. Dr. Bladin agrees and would like to pursue a phase 3 trial with a modified design to answer questions raised by Dr. Chun and others.

“The next phase could consider changing the primary outcome to an ordinal shift analysis on modified Rankin Scale – a very commonly used primary outcome in stroke clinical trials to assess improvement in disability,” Dr. Chun said. “The primary outcome used in the presented trial – an 8-point improvement on NIHSS – seemed too ambitious and does not inform disability of the patient post stroke.”

Dr. Bladin said he would also like to see the next phase enroll more patients, examine a higher dose of exenatide, and include better stratification of patients with a history of diabetes. Such a trial could yield findings demonstrating the drug’s effectiveness at reducing hyperglycemia and improving outcomes after stroke, he said.

“I can see the day patients will come in with acute stroke, and as they’re coming into the emergency department, they’ll simply get their shot of exenatide because we know it’s safe to use, and it doesn’t cause hypoglycemia,” Dr. Bladin said. “And from the moment that patient arrives the glucose control is underway.”

Dr. Bladin and Dr. Chun reported no relevant financial relationships. Study funding was not disclosed.

Can fecal transplants help reverse aging? 

Article Type
Changed
Thu, 05/12/2022 - 15:26

 

Transplanting fecal microbiota from young mice into older mice can reverse signs of aging in the gut, brain, and eyes, a team of scientists from the United Kingdom has found. Conversely, transplanting microbiota from old mice to young mice has the opposite effect.

This research provides “tantalizing evidence for the direct involvement of gut microbes in aging and the functional decline of brain function and vision and offers a potential solution in the form of gut microbe replacement therapy,” Simon Carding, PhD, who heads the gut microbes and health research program at the Quadram Institute in Norwich, England, said in a news release.

The study was published online in the journal Microbiome.

The fountain of youth?

Age-related changes in diversity, composition, and function of the gut microbiota are associated with low-grade systemic inflammation, declining tissue function, and increased susceptibility to age-related chronic diseases.

Dr. Carding and colleagues at the Quadram Institute and the University of East Anglia used fecal microbiota transplant (FMT) to exchange the intestinal microbiota of young mice and aged mice.

Young mice who received aged microbiota showed increased intestinal barrier permeability (leaky gut) coupled with upregulated inflammation in the brain and retina, as well as loss of a key functional protein in the eye, they report.

Conversely, these detrimental effects were reversed when microbiota from young mice was transferred to aged mice. FMT with young microbiota also led to enrichment of beneficial taxa in aged mice.

“Our data support the suggestion that altered gut microbiota in old age contributes to intestinal and systemic inflammation, and so may contribute to driving inflammatory pathologies of aged organs,” the study team wrote.

“Targeting the gut-brain axis in aging, by modification of microbial composition to modulate immune and metabolic pathways, may therefore be a potential avenue for therapeutic approaches to age-associated inflammatory and functional decline,” they suggested.

In ongoing studies, the study team are working to understand how long the beneficial effects of young donor microbiota last, which will establish whether FMT can promote long-term health benefits in aged individuals and ameliorate age-associated neurodegeneration and retinal functional deterioration.

“Our results provide more evidence of the important links between microbes in the gut and healthy aging of tissues and organs around the body,” lead author Aimée Parker, PhD, from the Quadram Institute, said in the release.

“We hope that our findings will contribute ultimately to understanding how we can manipulate our diet and our gut bacteria to maximize good health in later life,” she added.

‘Goodie bag’ pill mill doctor sentenced to 2 decades in prison

Article Type

Thu, 05/12/2022 - 13:29

 

A Pennsylvania-based internist was sentenced to 20 years in prison by a federal judge on May 10 for running a prescription “pill mill” from his medical practice.

Since May 2005, Andrew Berkowitz, MD, 62, of Huntington Valley, Pa., was president and CEO of A+ Pain Management, a clinic in the Philadelphia area, according to his LinkedIn profile.

Prosecutors said patients, no matter their complaint, would leave Dr. Berkowitz’s offices with “goodie bags” filled with a selection of drugs. A typical haul included topical analgesics, such as Relyyt and/or lidocaine; muscle relaxants, including chlorzoxazone and/or cyclobenzaprine; anti-inflammatories, such as celecoxib and/or fenoprofen; and schedule IV substances, including tramadol, eszopiclone, and quazepam.

The practice was registered in Pennsylvania as a nonpharmacy dispensing site, allowing Dr. Berkowitz to bill insurers for the drugs, according to The Pennsylvania Record, a journal covering Pennsylvania’s legal system. Dr. Berkowitz also prescribed oxycodone for “pill seeking” patients, who gave him their tacit approval of submitting claims to their insurance providers, which included Medicare, Aetna, and others, for the items in the goodie bag.

In addition, Dr. Berkowitz fraudulently billed insurers for medically unnecessary physical therapy, acupuncture, and chiropractic adjustments, as well as for treatments that were never provided, according to federal officials.

According to the Department of Justice, Dr. Berkowitz collected more than $4,000 per bag from insurers. From 2015 to 2018, prosecutors estimate that Dr. Berkowitz took in more than $4 million in fraudulent proceeds from his scheme.

The pill mill came to the attention of federal authorities after Blue Cross investigators forwarded to the FBI several complaints it had received about Dr. Berkowitz. In 2017, the FBI sent a cooperating witness to Dr. Berkowitz’s clinic. The undercover patient received a prescription for oxycodone, Motrin, and Flexeril and paid $185, according to The Record.

After being indicted in 2019, Dr. Berkowitz pleaded guilty in January 2020 to 19 counts of health care fraud and to 23 counts of distributing oxycodone outside the course of professional practice and without a legitimate medical purpose.

On May 10, he was sentenced to 20 years in prison, followed by 5 years of supervised release. In addition, he was ordered to pay a $40,000 fine and almost $4 million in restitution. As a result of civil False Claims Act liability for false claims submitted to Medicare, he is also obligated to pay approximately $1.8 million and is subject to a permanent prohibition on prescribing, distributing, or dispensing controlled substances.

Dr. Berkowitz’s actions were deemed especially egregious in light of the opioid epidemic.

“Doctors are supposed to treat illness, not feed it,” said Jacqueline Maguire, special agent in charge of the FBI’s Philadelphia division. “Andrew Berkowitz prescribed patients unnecessary pills and handed out opioids to addicts.” Jennifer Arbittier Williams, acting U.S. Attorney, added upon announcing the sentence, “Doctors who dare engage in health care fraud and drug diversion, two drivers of the opioid epidemic ravaging our communities, should heed this sentence as a warning that they will be held responsible, criminally and financially.”

In addition, Dr. Berkowitz fraudulently billed insurers for medically unnecessary physical therapy, acupuncture, and chiropractic adjustments, as well as for treatments that were never provided, according to federal officials.

According to the Department of Justice, Dr. Berkowitz collected more than $4,000 per bag from insurers. From 2015 to 2018, prosecutors estimate that Dr. Berkowitz took in more than $4 million in fraudulent proceeds from his scheme.

The pill mill came to the attention of federal authorities after Blue Cross investigators forwarded to the FBI several complaints it had received about Dr. Berkowitz. In 2017, the FBI sent a cooperating witness to Dr. Berkowitz’s clinic. The undercover patient received a prescription for oxycodone, Motrin, and Flexeril and paid $185, according to The Record.

After being indicted in 2019, Dr. Berkowitz pleaded guilty in January 2020 to 19 counts of health care fraud and to 23 counts of distributing oxycodone outside the course of professional practice and without a legitimate medical purpose.

On May 10, he was sentenced to 20 years in prison, followed by 5 years of supervised release. In addition, he was ordered to pay a $40,000 fine and almost $4 million in restitution. As a result of civil False Claims Act liability for false claims submitted to Medicare, he is also obligated to pay approximately $1.8 million and is subject to a permanent prohibition on prescribing, distributing, or dispensing controlled substances.

Dr. Berkowitz’s actions were deemed especially egregious in light of the opioid epidemic.

“Doctors are supposed to treat illness, not feed it,” said Jacqueline Maguire, special agent in charge of the FBI’s Philadelphia division. “Andrew Berkowitz prescribed patients unnecessary pills and handed out opioids to addicts.” Jennifer Arbittier Williams, acting U.S. Attorney, added upon announcing the sentence, “Doctors who dare engage in health care fraud and drug diversion, two drivers of the opioid epidemic ravaging our communities, should heed this sentence as a warning that they will be held responsible, criminally and financially.”

ED staff speak out about workplace violence, ask for mitigation

WASHINGTON – Speaker after speaker, veteran emergency department physicians and nurses approached the podium for a May 4 press conference on the U.S. Capitol lawn across from the East Senate steps to describe violent incidents – being bitten, punched, slapped, kicked, choked, spat on, threatened – that they have both observed and have been subject to while working in EDs.

The press conference was cosponsored by the American College of Emergency Physicians and the Emergency Nurses Association, which have partnered since 2019 on the No Silence on ED Violence campaign.

The numbers confirm their experience. A 2018 poll of 3,500 ED physicians nationwide, which was conducted by Marketing General and was reported at ACEP’s annual meeting, found that nearly half of respondents had been assaulted at work; 27% of them were injured from the assault. Nurses, who spend more time with patients, may face even higher rates.

Incidence was reported to be increasing in 2018, and that was before the social and psychological upheavals imposed by the COVID pandemic caused assaults on staff in the hospital to go up an estimated 200%-300%.

But what really grated was that more than 95% of such cases, mostly perpetrated by patients, were never prosecuted, said Jennifer Casaletto, MD, FACEP, a North Carolina emergency physician and president of the state’s ACEP chapter. “Hospital and law enforcement see violence as just part of the job in our EDs.”

It’s no secret that workplace violence is increasing, Dr. Casaletto said. Four weeks ago, she stitched up the face of a charge nurse who had been assaulted. The nurse didn’t report the incident because she didn’t believe anything would change.

“Listening to my colleagues, I know the terror they have felt in the moment – for themselves, their colleagues, their patients. I know that raw fear of being attacked, and the complex emotions that follow. I’ve been hit, bit, and punched and watched colleagues getting choked.”

Dr. Casaletto was present in the ED when an out-of-control patient clubbed a nurse with an IV pole as she tried to close the doors to other patients’ rooms. “Instinctively, I pulled my stethoscope from around my neck, hoping I wouldn’t be strangled with it.”



Tennessee emergency nurse Todd Haines, MSN, RN, AEMT, CEN, said he has stepped in to help pull patients off coworkers. “I’ve seen some staff so severely injured they could not return to the bedside. I’ve been verbally threatened. My family has been threatened by patients and their families,” he reported. “We’ve all seen it. And COVID has made some people even meaner. They just lose their minds, and ED staff take the brunt of their aggression. But then to report these incidents and hear: ‘It’s just part of your job,’ well, it’s not part of my job.”

Mr. Haines spent 10 years in law enforcement with a sheriff’s department in middle Tennessee and was on its special tactical response team before becoming an ED nurse. He said he saw many more verbal and physical assaults in 11 years in the ED than during his police career.

“I love emergency nursing at the bedside, but it got to the point where I took the first chance to leave the bedside. And I’m not alone. Other nurses are leaving in droves.” Mr. Haines now has a job directing a trauma program, and he volunteers on policy issues for the Tennessee ENA. But he worries about the toll of this violence on the ED workforce, with so many professionals already mulling over leaving the field because of job stress and burnout.

“We have to do something to keep experienced hospital emergency staff at the bedside.”

 

What’s the answer?

Also speaking at the press conference was Senator Tammy Baldwin (D-Wis.), who pledged to introduce the Workplace Violence Prevention for Health Care and Social Services Workers Act, which passed the House in April. This bill would direct the Occupational Health and Safety Administration to issue a standard requiring employers in health care and social services to develop and implement workplace violence prevention plans. It would cover a variety of health facilities but not doctor’s offices or home-based services.

An interim final standard would be due within a year of enactment, with a final version to follow. Covered employers would have 6 months to develop and implement their own comprehensive workplace violence prevention plans, with the meaningful participation of direct care employees, tailored for and specific to the conditions and hazards of their facility, informed by past violent incidents, and subject to the size and complexity of the setting.

The plan would also name an individual responsible for its implementation, would include staff training and education, and would require facilities to track incidents and prohibit retaliation against employees who reported incidents of workplace violence.

On Wednesday, Sen. Baldwin called for unanimous consent on the Senate floor to fast-track this bill, but that was opposed by Senator Mike Braun (R-Ind.). She will soon introduce legislation similar to HR 1195, which the House passed.

“This bill will provide long overdue protections and safety standards,” she said. It will ensure that workplaces adopt proven protection techniques, such as those in OSHA’s 2015 guideline for preventing health care workplace violence. The American Hospital Association opposed the House bill on the grounds that hospitals have already implemented policies and programs specifically tailored to address workplace violence, so the OSHA standards required by the bill are not warranted.

Another speaker at the press conference, Aisha Terry, MD, MPH, FACEP, an emergency physician for George Washington University and Veterans Affairs in Washington, D.C., and current vice president of ACEP, described an incident that occurred when she was at work. A patient punched the nurse caring for him in the face, knocking her unconscious to the floor. “I’ll never forget that sound,” Dr. Terry said. “To this day, it has impacted her career. She hasn’t known what to do.”

Many people don’t realize how bad workplace violence really is, Dr. Terry added. “You assume you can serve as the safety net of this country, taking care of patients in the context of the pandemic, and feel safe – and not have to worry about your own safety. It’s past due that we put an end to this.”
 

Biggest win

Mr. Haines called the workplace violence bill a game changer for ED professionals, now and into the future. “We’re not going to totally eliminate violence in the emergency department. That is part of our business. But this legislation will support us and give a safer environment for us to do the work we love,” he said.

“The biggest win for this legislation is that it will create a supportive, nonretaliatory environment. It will give us as nurses a structured way to report things.” And, when these incidents do get reported, staff will get the help they need, Mr. Haines said. “The legislation will help show the importance of implementing systems and processes in emergency settings to address the risks and hazards that makes us all vulnerable to violence.”

No relevant financial relationships have been disclosed.

Neurology, psychiatry studies overlook sex as a variable

Article Type
Changed
Thu, 05/12/2022 - 13:38

A large percentage of studies in neurology and psychiatry over the past decade have failed to account for differences between the sexes, according to a team of Canadian researchers.

In a survey of more than 3,000 papers published in six neuroscience and psychiatry journals from 2009 to 2019, researchers found that only 5% analyzed sex as a variable.

Dr. Liisa Galea

“Despite the fact there are papers that are using males and females in the studies, they’re not using the males and females in the way that would optimally find the possibility of sex differences,” lead author Liisa A.M. Galea, PhD, told this news organization. Dr. Galea is a professor and distinguished scholar at the Djavad Mowafaghian Center for Brain Health at the University of British Columbia in Vancouver.

The study was published online in Nature Communications.
 

Optimal design uncommon

Differences in how neurologic and psychiatric diseases affect men and women have been well documented. Women, for example, are more susceptible to severe stroke, and men are more prone to cognitive decline with schizophrenia. With Alzheimer’s disease, women typically have more severe cognitive defects.

The researchers surveyed 3,193 papers that included a multitude of studies. Although most of the papers reported studies that included both sexes, only 19% of surveyed studies used what Dr. Galea called an optimal design for the discovery of sex differences. “What I mean by ‘optimally’ is the design of the experiments and the analysis of sex as a variable,” she said. And in 2019, only 5% of the studies used sex as a variable for determining differences between the sexes, the study found.

In the current research, two authors read the methods and results of each study described in each paper, Dr. Galea said. The readers noted whether the paper reported the study sample size and whether the studies used a balanced design. The surveyed journals include Nature Neuroscience, Neuron, Journal of Neuroscience, Molecular Psychiatry, Biological Psychiatry, and Neuropsychopharmacology.
 

‘Not much is changing’

“I had a suspicion that this was happening,” Dr. Galea said. “I didn’t know that it’s so bad, to be fair.” The “good news story,” she said, is that more papers considered sex as a factor in the later years surveyed. In 2019, more than 95% of papers across both disciplines reported participants’ sex, compared with about 70% in 2009. However, less than 20% of the papers in all study years reported studies that used sex optimally to determine differences between the sexes.

“The other thing that shocked me,” Dr. Galea said, “was that even despite the fact that we saw this increase in the number of papers that were using males and females, we didn’t see the sort of corresponding increase in those that were using ‘optimal design’ or ‘optimal analysis,’ ” Dr. Galea said. In 2009, 14% of papers used optimal design and 2% used optimal analysis for determining sex differences. By 2019, those percentages were 19% and 5%, respectively.

But even the papers that used both sexes had shortcomings, the study found. Just over one-third of these papers (34.5%) didn’t use a balanced design. Just over one-quarter (25.9%) didn’t identify the sample size, a shortcoming that marked 18% of these studies in 2009 and 33% in 2019. Fifteen percent of papers examined included studies that used both sexes inconsistently.

“That matters, because other studies have found that about 20% of papers are doing some kind of analysis with sex, but we had a suspicion that a lot of studies would include sex as a covariate,” Dr. Galea said. “Essentially what that does is, you remove that variable from the data. So, any statistical variation due to sex is then gone.

“The problem with that,” she added, “is you’re not actually looking to see if there’s an influence of sex; you’re removing it.”

Dr. Galea noted that this study points to a need for funding agencies to demand that researchers meet their mandates on sex- and gender-based analysis. “Despite the mandates, not much is really changing as far as the analysis or design of experiments, and we need to figure out how to change that,” she said. “We need to figure out how to get researchers more interested to use the power of studying sex differences.”
 

 

 

‘Not surprising, but disappointing’

Vladimir Hachinski, MD, professor of neurology and epidemiology at Western University in London, Ont., and former editor in chief of Stroke, told this news organization that women have almost twice the life risk of developing dementia, are at higher risk of stroke below age 35 years, and have more severe strokes and higher rates of disability at any age.

Dr. Vladimir Hachinski

Commenting on the current study, Dr. Hachinski said, “It’s not surprising, but it’s disappointing, because we’ve known the difference for a long time.” He added, “The paper is very important because we were not aware that it was that bad.”

Dr. Hachinski also stated, “This paper needs a lot of reading. It’s a great resource, and it should be highlighted as one of those things that needs to be addressed, because it matters.”

The study was funded by a Natural Sciences and Engineering Research Council of Canada grant and by the British Columbia Women’s Foundation. Dr. Galea and Hachinski had no relevant disclosures.

The study was funded by a Natural Sciences and Engineering Research Council of Canada grant and by the British Columbia Women’s Foundation. Dr. Galea and Hachinski had no relevant disclosures.

A large percentage of studies in neurology and psychiatry over the past decade have failed to account for differences between the sexes, according to a team of Canadian researchers.

In a survey of more than 3,000 papers published in six neuroscience and psychiatry journals from 2009 to 2019, researchers found that only 5% analyzed sex as a variable.

Dr. Liisa Galea

“Despite the fact there are papers that are using males and females in the studies, they’re not using the males and females in the way that would optimally find the possibility of sex differences,” lead author Liisa A.M. Galea, PhD, told this news organization. Dr. Galea is a professor and distinguished scholar at the Djavad Mowafaghian Center for Brain Health at the University of British Columbia in Vancouver.

The study was published online in Nature Communications.
 

Optimal design uncommon

Differences in how neurologic and psychiatric diseases affect men and women have been well documented. Women, for example, are more susceptible to severe stroke, and men are more prone to cognitive decline with schizophrenia. With Alzheimer’s disease, women typically have more severe cognitive defects.

The researchers surveyed 3,193 papers that included a multitude of studies. Although most of the papers reported studies that included both sexes, only 19% of surveyed studies used what Dr. Galea called an optimal design for the discovery of sex differences. “What I mean by ‘optimally’ is the design of the experiments and the analysis of sex as a variable,” she said. And in 2019, only 5% of the studies used sex as a variable for determining differences between the sexes, the study found.

In the current research, two authors read the methods and results of each study described in each paper, Dr. Galea said. The readers noted whether the paper reported the study sample size and whether the studies used a balanced design. The surveyed journals include Nature Neuroscience, Neuron, Journal of Neuroscience, Molecular Psychiatry, Biological Psychiatry, and Neuropsychopharmacology.
 

‘Not much is changing’

“I had a suspicion that this was happening,” Dr. Galea said. “I didn’t know that it’s so bad, to be fair.” The “good news story,” she said, is that more papers considered sex as a factor in the later years surveyed. In 2019, more than 95% of papers across both disciplines reported participants’ sex, compared with about 70% in 2009. However, less than 20% of the papers in all study years reported studies that used sex optimally to determine differences between the sexes.

“The other thing that shocked me,” Dr. Galea said, “was that even despite the fact that we saw this increase in the number of papers that were using males and females, we didn’t see the sort of corresponding increase in those that were using ‘optimal design’ or ‘optimal analysis,’ ” Dr. Galea said. In 2009, 14% of papers used optimal design and 2% used optimal analysis for determining sex differences. By 2019, those percentages were 19% and 5%, respectively.

But even the papers that used both sexes had shortcomings, the study found. Just over one-third of these papers (34.5%) didn’t use a balanced design. Just over one-quarter (25.9%) didn’t identify the sample size, a shortcoming that marked 18% of these studies in 2009 and 33% in 2019. Fifteen percent of papers examined included studies that used both sexes inconsistently.

“That matters, because other studies have found that about 20% of papers are doing some kind of analysis with sex, but we had a suspicion that a lot of studies would include sex as a covariate,” Dr. Galea said. “Essentially what that does is, you remove that variable from the data. So, any statistical variation due to sex is then gone.

“The problem with that,” she added, “is you’re not actually looking to see if there’s an influence of sex; you’re removing it.”

Dr. Galea noted that this study points to a need for funding agencies to demand that researchers meet their mandates on sex- and gender-based analysis. “Despite the mandates, not much is really changing as far as the analysis or design of experiments, and we need to figure out how to change that,” she said. “We need to figure out how to get researchers more interested to use the power of studying sex differences.”
 

 

 

‘Not surprising, but disappointing’

Vladimir Hachinski, MD, professor of neurology and epidemiology at Western University in London, Ont., and former editor in chief of Stroke, told this news organization that women have almost twice the life risk of developing dementia, are at higher risk of stroke below age 35 years, and have more severe strokes and higher rates of disability at any age.

Study casts doubt on safety, efficacy of L-serine supplementation for AD

While previous research suggests that dietary supplementation with L-serine may be beneficial for patients with Alzheimer’s disease (AD), a new study cast doubt on the potential efficacy, and even the safety, of this treatment.

When given to patients with AD, L-serine supplements could be driving abnormally increased serine levels in the brain even higher, potentially accelerating neuronal death, according to study author Xu Chen, PhD, of the University of California, San Diego, and colleagues.

This conclusion conflicts with a 2020 study by Juliette Le Douce, PhD, and colleagues, who reported that oral L-serine supplementation may act as a “ready-to-use therapy” for AD, based on their findings that patients with AD had low levels of PHGDH, an enzyme necessary for synthesizing serine, and AD-like mice had low levels of serine.

Dr. Sheng Zhong

Writing in Cell Metabolism, Dr. Chen and colleagues framed the present study, and their findings, in this context.

“In contrast to the work of Le Douce et al., here we report that PHGDH mRNA and protein levels are increased in the brains of two mouse models of AD and/or tauopathy, and are also progressively increased in human brains with no, early, and late AD pathology, as well as in people with no, asymptomatic, and symptomatic AD,” they wrote.

They suggested adjusting clinical recommendations for L-serine, the form of the amino acid commonly found in supplements. In the body, L-serine is converted to D-serine, which acts on the NMDA receptor (NMDAR).

‘Long-term use of D-serine contributes to neuronal death’ suggests research

“We feel oral L-serine as a ready-to-use therapy to AD warrants precaution,” Dr. Chen and colleagues wrote. “This is because despite being a cognitive enhancer, some [research] suggests that long-term use of D-serine contributes to neuronal death in AD through excitotoxicity. Furthermore, D-serine, as a co-agonist of NMDAR, would be expected to oppose NMDAR antagonists, which have proven clinical benefits in treating AD.”

According to principal author Sheng Zhong, PhD, of the University of California, San Diego, “Research is needed to test if targeting PHGDH can ameliorate cognitive decline in AD.”

Dr. Zhong also noted that the present findings support the “promise of using a specific RNA in blood as a biomarker for early detection of Alzheimer’s disease.” This approach is currently being validated at UCSD Shiley-Marcos Alzheimer’s Disease Research Center, he added.

Roles of PHGDH and serine in Alzheimer’s disease require further study

Commenting on both studies, Steve W. Barger, PhD, of the University of Arkansas for Medical Sciences, Little Rock, suggested that more work is needed to better understand the roles of PHGDH and serine in AD before clinical applications can be considered.

“In the end, these two studies fail to provide the clarity we need in designing evidence-based therapeutic hypotheses,” Dr. Barger said in an interview. “We still do not have a firm grasp on the role that D-serine plays in AD. Indeed, the evidence regarding even a single enzyme contributing to its levels is ambiguous.”

Dr. Barger, who has published extensively on the topic of neuronal death, with a particular focus on Alzheimer’s disease, noted that “determination of what happens to D-serine levels in AD has been of interest for decades,” but levels of the amino acid have been notoriously challenging to measure because “D-serine can disappear rapidly from the brain and its fluids after death.”

While Dr. Le Douce and colleagues did measure levels of serine in mice, Dr. Barger noted that the study by Dr. Chen and colleagues was conducted with more “quantitatively rigorous methods.” Even though Dr. Chen and colleagues “did not assay the levels of D-serine itself ... the implication of their findings is that PHGDH is poised to elevate this critical neurotransmitter,” leading to their conclusion that serine supplementation is “potentially dangerous.”

At this point, it may be too early to tell, according to Dr. Barger.

He suggested that conclusions drawn from PHGDH levels alone are “always limited,” and conclusions based on serine levels may be equally dubious, considering that the activities and effects of serine “are quite complex,” and may be influenced by other physiologic processes, including the effects of gut bacteria.

Instead, Dr. Barger suggested that changes in PHGDH and serine may be interpreted as signals coming from a more relevant process upstream: glucose metabolism.

“What we can say confidently is that the glucose metabolism that PHGDH connects to D-serine is most definitely a factor in AD,” he said. “Countless studies have documented what now appears to be a universal decline in glucose delivery to the cerebral cortex, even before frank dementia sets in.”

Dr. Barger noted that declining glucose delivery coincides with some of the earliest events in the development of AD, perhaps “linking accumulation of amyloid β-peptide to subsequent neurofibrillary tangles and tissue atrophy.”

Dr. Barger’s own work recently demonstrated that AD is associated with “an irregularity in the insertion of a specific glucose transporter (GLUT1) into the cell surface” of astrocytes.

“It could be more effective to direct therapeutic interventions at these events lying upstream of PHGDH or serine,” he concluded.

The study was partly supported by a Kreuger v. Wyeth research award. The investigators and Dr. Barger reported no conflicts of interest.

Headache in pregnancy: New ACOG guidelines offer insight

Article Type
Changed
Tue, 06/07/2022 - 11:16

– If a medical professional is trying to figure out the best medical treatment for a pregnant woman with headache, it may be helpful to review data from randomized clinical trials (RCTs). Well, make that data from the RCT. There’s just been one, Northwestern Medicine obstetrician-gynecologist Catherine Stika, MD, told colleagues at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists.

Only a single efficacy RCT has examined headache in pregnancy, said Dr. Stika. “Overall, we have very limited data in pregnancy to tell us exactly what to do,” she added.

But ob.gyns. aren’t entirely in the dark, according to medical specialists who spoke at the session. Expert opinion and fetal safety data offer insight into the best treatments, as does a new ACOG clinical practice guideline on headaches during pregnancy and post partum that was coauthored by the speakers.

And there’s some good news: Pregnancy itself is often a good treatment for headaches.

Pregnant women often find relief from one kind of headache – migraine – as their estradiol levels rise, said Laura Mercer, MD, an ob.gyn. at the University of Arizona, Phoenix. “About half of patients will report that migraines are getting better as early as the first trimester, and upwards of 83% will say that their migraines are better by the time they’re in their third trimester,” she said. “What this means for us as obstetricians is that oftentimes we can actually discontinue preventative therapies for patients during pregnancy.”

But simply discontinuing every headache treatment during pregnancy may not be the right approach, Dr. Mercer said. Instead, she said, consider the benefits and risks.

Divalproex sodium (Depakote) and topiramate (Topamax) must be avoided because of fetal risk, she said. “In fact, we will prefer that people stop these medications before they discontinue their contraception if they’re planning on getting pregnant,” she said.

Other medications, such as ACE inhibitors and the herbal remedy feverfew, should not be used at any time during pregnancy, she said.

On the other hand, calcium channel blockers and antihistamines are alright to use in pregnancy, she said. “These two should be considered first-line because there’s no known risks for them.”

Beta-blockers also may be used “with some consideration to the known risks that we’re familiar with when we use them for other indications,” she said.

There are questions about the safety of oral magnesium in pregnancy, although it’s generally considered safe, she added, and “nerve blocks and nerve stimulators seem very promising and have little known risks.”

Dr. Mercer recommended gradually tapering most medications prior to conception. But it’s crucial to stop higher-risk drugs immediately once pregnancy is confirmed, she said.

In regard to acute headache, Dr. Stika urged caution if a patient reports taking a headache medication more than twice a week. “All the medications we use for the treatment of migraine, both in and outside of pregnancy, carry the risk of what’s called medication overuse” that can lead to rebound headaches, she said.

Excedrin Tension Headache may be used for headaches in pregnancy, she said, but not Excedrin Migraine since it includes aspirin. Triptans are not recommended as first-line therapy, she added, and they “should absolutely not be used in any pregnant patient with a history of known cardiac disease or hypertension.”

Dr. Stika added that ACOG advises against the use of drugs that contain butalbital, a barbiturate that’s combined with other agents to treat headache. “Butalbital is the drug that’s most closely associated with getting people into this medication overuse headache,” she said. “It’s even worse than opioids.”

Unlike multiple other countries and the entire European Union, the United States has not banned compounds that contain butalbital, she said.

In some cases, she said, patients may present to triage with vomiting, an inability to keep food down, and persistent headache despite treatment. “This is a really classic presentation.”

The ACOG clinical practice guideline offers a flow chart about what to do, she said. Hydration is key, she said, and various treatment options can help. A referral to neurology may be needed in extreme cases, she said. But “most of the time, you’re able to get rid of her headache.”

Dr. Mercer and Dr. Stika report no disclosures.

Triptans are not recommended as first-line therapy, she added, and they “should absolutely not be used in any pregnant patient with a history of known cardiac disease or hypertension.”

Dr. Stika added that ACOG advises against the use of drugs that contain butalbital, a barbiturate that’s combined with other agents to treat headache. “Butalbital is the drug that’s most closely associated with getting people into this medication overuse headache,” she said. “It’s even worse than opioids.”

Unlike multiple other countries and the entire European Union, the United States has not banned compounds that contain butalbital, she said.

In some cases, she said, patients may present to triage with vomiting, an inability to keep food down, and persistent headache despite treatment. “This is a really classic presentation.”

The ACOG clinical practice guideline offers a flow chart about what to do, she said. Hydration is key, she said, and various treatment options can help. A referral to neurology may be needed in extreme cases, she said. But “most of the time, you’re able to get rid of her headache.”

Dr. Mercer and Dr. Stika report no disclosures.
