At-term birth timing may cut preeclampsia risk in half
Timed birth strategies include scheduled labor inductions and cesarean deliveries.
In this observational analysis of nearly 90,000 pregnancies, at-term preeclampsia occurred with similar frequency among women routinely screened during the first trimester and among at-risk women screened during the third trimester.
Overall, on average, at-risk women delivered at 40 weeks, with two-thirds experiencing spontaneous onset of labor. About one-fourth had cesarean deliveries.
“We anticipated that timed birth at 37 weeks could reduce the occurrence of more than half of preeclampsia, [but] this is not an intervention that could be recommended, as complications for the baby would be increased,” Laura A. Magee, MD, of King’s College London, told this news organization.
“However, we were delighted to see that a personalized approach to timed birth, based on an individual woman’s risk of preeclampsia, could prevent a similar number of cases of preeclampsia, with fewer women requiring timed birth and at later gestational ages, when newborn problems would be less frequent.”
Although not currently recommended to prevent at-term preeclampsia, “timed birth by labor induction is a very common timing of birth strategy,” she noted. “At least one-third of women currently undergo labor induction at term gestational age, and one in six choose to deliver by elective cesarean.”
The study was published online in the journal Hypertension.
Screening at 35-36 weeks superior
The investigators analyzed data from a nonintervention cohort study of singleton pregnancies delivering at ≥ 24 weeks, without major anomalies, at two U.K. hospitals.
At routine visits at 11-13 weeks’ gestation, 57,131 pregnancies were screened, and 1,138 term preeclampsia cases developed.
Most of these women were in their early 30s, self-identified as White, and had a BMI at the upper limits of normal. About 10% were smokers; fewer than 3% had a medical history of high blood pressure, type 2 diabetes, or autoimmune disease; and 3.9% reported a family history of preeclampsia.
At 35-36 weeks, in a different cohort, 29,035 pregnancies were screened and term preeclampsia developed in 619 women. Demographics and pregnancy characteristics were similar to those screened at 11-13 weeks, although the average BMI was higher – in the overweight range – and there were fewer Black women, although they still made up 10% of the screened population.
Patient-specific preeclampsia risks were determined by the United Kingdom National Institute for Health and Care Excellence (NICE) guidance, and the Fetal Medicine Foundation competing-risks model, available through an online calculator.
Timing of birth for term preeclampsia prevention was evaluated at 37, 38, 39, and 40 weeks or depending on preeclampsia risk by the competing-risks model at 35-36 weeks.
The primary outcomes were the proportion of term preeclampsia prevented, and number-needed-to-deliver to prevent one term preeclampsia case.
The investigators found that overall, the proportion of term preeclampsia prevented was highest, and number-needed-to-deliver lowest, for preeclampsia screening at 35-36 weeks rather than at 11-13 weeks.
For delivery at 37 weeks, fewer cases of preeclampsia were prevented with NICE criteria (28.8%) than with the competing-risks model (59.8%), and the number-needed-to-deliver was higher (16.4 vs 6.9, respectively).
At 35-36 weeks, the risk-stratified approach had similar preeclampsia prevention (57.2%) and number-needed-to-deliver (8.4), but fewer women would be induced at 37 weeks (1.2% vs. 8.8%).
Although personalized timed birth at term may be an effective way to address at-term preeclampsia, “clinicians should wait for definitive clinical trial evidence,” Dr. Magee said.
‘Stay tuned’
Vesna D. Garovic, MD, PhD, Mayo Clinic, Rochester, Minn., and chair of the 2021 AHA Scientific Statement, “Hypertension in Pregnancy: Diagnosis, Blood Pressure Goals, and Pharmacotherapy,” agrees.
The new data “set the stage for adequately designed and powered studies that will provide ultimate response/evidence regarding the efficacy of this approach,” she told this news organization.
“Future studies need to address the safety of this approach,” she added, “as close to 10 timed/planned deliveries will be needed to prevent one case of preeclampsia.”
For now, she said, “While these preliminary data are promising, they are not sufficient to adopt timed birth in daily practice. Prospective studies that will provide sufficient evidence regarding the efficacy and safety of this approach are likely to follow. Stay tuned.”
Indeed, Dr. Magee noted that the Fetal Medicine Foundation is about to launch a randomized trial of a personalized “timing of birth” strategy at term based on the preeclampsia risk described in her group’s study vs. usual care at term – that is, “watchful waiting, and delivery should preeclampsia or another indication for birth develop.”
The study was supported by grants from the Fetal Medicine Foundation, United Kingdom, and various biotech companies provided reagents and relevant equipment free of charge. Dr. Magee and Dr. Garovic reported no relevant financial relationships.

Cardiovascular disease deaths rise on and after high-pollution days
Cardiovascular disease deaths were significantly more common on days of high pollution and for the following 2 days, compared with other days, based on data from nearly 88,000 deaths over a 5-year period.
Previous research has shown the harmful effect of air pollution on human health in highly polluted areas, but Eastern Poland, a region with so-called “Polish smog” has exceptionally high levels of pollution. However, the specific impact of Polish smog, caused primarily by burning coal, on cardiovascular disease (CVD) mortality has not been well studied, said Michal Swieczkowski, MD, of the Medical University of Bialystok (Poland) in a presentation at the annual congress of the European Association of Preventive Cardiology.
Dr. Swieczkowski and colleagues reviewed all-cause deaths from five main cities in Eastern Poland during 2016-2020 for associations with pollution levels and days when deaths occurred. Mortality data were obtained from the Central Statistical Office. Air pollution concentrations for two types of particulate matter (PM2.5, PM10) and nitrogen oxide were collected from the Voivodeship Inspectorate for Environmental Protection. The main sources of the pollutants were road traffic and household heaters using coal or wood.
The final analysis included nearly 6 million person-years of follow-up. The researchers used a time-stratified case-crossover design. For each participant, the researchers compared levels of each pollutant on the day of the week a death occurred (such as a Wednesday) with pollutant levels on the same day of the week without any deaths in the same month (the remaining Wednesdays of that month). This design eliminated the potential confounding effects of participant characteristics, including other cardiovascular risk factors such as smoking and hyperlipidemia, and time trends. Essentially, participants “served as their own controls,” Dr. Swieczkowski said. The researchers conducted similar analyses for pollution levels 1 day and 2 days before a death occurred.
Overall, 87,990 deaths were identified during the study period; of these, 34,907 were from CVD, 9,688 from acute coronary syndromes, and 3,776 from ischemic stroke.
“Exposure to PM2.5 and PM10 was associated with increased mortality on the day of exposure, the next day, and up to 2 days after exposure,” said Dr. Swieczkowski.
Overall, an increase of 10 mcg/m3 in the three pollutants was significantly associated with increase in CVD mortality on the day of exposure to the increased pollution levels, with odds ratios of 1.034, 1.033, and 1.083 for PM2.5, PM10, and NO2, respectively (all P < .001).
The risks of dying from CVD were similar 1 and 2 days after the polluted day.
An increase in PM levels, but not NO2, was significantly associated with acute coronary syndrome (ACS) on the day of exposure to increased pollutants (ORs, 1.029 for PM2.5 [P = .002] and 1.015 [P = .049] for PM10). Both ischemic stroke and ACS mortality were significantly higher at 1 day after exposure, compared with other days. Ischemic stroke was associated with increases in PM2.5 and PM10, while ACS was associated with increases in PM2.5, PM10, and NO2.
When stratified by gender, the effects were more noticeable in women, Dr. Swieczkowski said. “Exposure to both types of particulate caused increased mortality due to acute coronary syndrome as well as ischemic stroke.” Among men, only death from acute coronary syndrome was significantly associated with exposure to increased particulate matter.
In a head-to-head comparison, women were more vulnerable to air pollution by up to 2.5%, he added.
When stratified by age, the effects of all three pollutants were associated with increased risk of death from ischemic stroke and ACS in participants older than 65 years. For those aged 65 years and younger, the only significant association was between ACS-associated mortality and ischemic stroke.
The results suggest “a special need for developing calculators to estimate the risk of CVD incidence depending on the place of residence that could be used for everyday practice,” said Dr. Swieczkowski. “Systemic changes should become a priority for policy makers, and, simultaneously, we as physicians should educate and protect our patients, especially those with high risk of cardiovascular disease,” he said.
Gender differences rooted in anatomy
When asked for an explanation of the difference in the impact of pollution on mortality between men and women, Dr. Swieczkowski explained that women are likely more vulnerable because of differences in anatomy of the pharynx and larynx, and breathing patterns. Previous studies have shown that air pollution causes more oxidative stress in women. Also, in the current study, the mean age of the women was 8 to 9 years older, he said.
The study design was an “elegant way to take away the impact of other cardiovascular risk factors,” noted session moderator Maryam Kavousi, MD, of Erasmus University Medical Center, Rotterdam, the Netherlands.
The study was supported by the National Science Centre, Poland. The researchers had no financial conflicts to disclose.

The World Health Organization estimates significant air pollution–attributable deaths, including 11% of lung cancer deaths, 18% of COPD deaths, and 23% of pneumonia deaths (www.who.org). (Carlsten C, et al. Europ Respir J. 2020;55[6]: 1902056).
The Environmental Protection Agency uses air quality (AQ) monitors around the country to track ambient pollution levels. These real-time data are available to the public on AirNow.gov; however, these data do not reflect indoor air pollutants. Thus, AQ monitors may not accurately represent the total air pollution exposure to patients.
Low-cost AQ monitors available for purchase enable indoor AQ monitoring.
Unfortunately, many indoor air pollutants do not have well-established safe levels. Although several devices detect specific pollutants like volatile oxygen compounds or particulate matter, other harmful compounds may remain undetectable and unmonitored. Even if high pollutant levels are detected, most devices are not designed to alarm like smoke and carbon monoxide detectors (www.epa.gov).
Although efficacy data are limited, several laboratories, such as the Indoor Environment Lab at Berkeley, have conducted performance evaluations. In a study of 16 devices publicly available for purchase, the devices tended to underreport pollutant levels by nearly 50%. Nevertheless, most devices successfully detected the presence of pollutants (Demanega I, et al. Building and Environment. 2021;187:107415).
Regardless of these limitations, low-cost AQ monitors may empower patients to intervene on unsafe household conditions and minimize their risk of poor lung health.

Even if high pollutant levels are detected, most devices are not designed to alarm like smoke and carbon monoxide detectors (www.epa.gov).
Although efficacy data are limited, several laboratories, such as the Indoor Environment Lab at Berkeley, have conducted performance evaluations. In a study of 16 devices publicly available for purchase, the devices tended to underreport pollutant levels by nearly 50%. Nevertheless, most devices successfully detected the presence of pollutants (Demanega I, et al. Building and Environment. 2021;187:107415).
Regardless of these limitations, low-cost AQ monitors may empower patients to intervene on unsafe household conditions and minimize their risk of poor lung health.

As COVID tracking wanes, are we letting our guard down too soon?
The 30-second commercial, part of the government’s We Can Do This campaign, shows everyday people going about their lives, then reminds them that, “because COVID is still out there and so are you,” it might be time to update your vaccine.
Many data tracking sources, both federal and others, are no longer reporting, as often, the number of COVID cases, hospitalizations, and deaths.
The Department of Health & Human Services in February stopped updating its public COVID data site, instead directing all queries to the Centers for Disease Control and Prevention, which itself has been updating only weekly instead of daily since 2022.
Nongovernmental sources, such as John Hopkins University, stopped reporting pandemic data in March, The New York Times also ended its COVID data-gathering project in March, stating that “the comprehensive real-time reporting that The Times has prioritized is no longer possible.” It will rely on reporting weekly CDC data moving forward.
Along with the tracking sites, masking and social distancing mandates have mostly disappeared. President Joe Biden signed a bipartisan bill on April 10 that ended the national emergency for COVID. While some programs will stay in place for now, such as free vaccines, treatments, and tests, that too will go away when the federal public health emergency expires on May 11. The HHS already has issued its transition roadmap.
Many Americans, meanwhile, are still on the fence about the pandemic. A Gallup poll from March shows that about half of the American public say it’s over, and about half disagree.
Are we closing up shop on COVID-19 too soon, or is it time? Not surprisingly, experts don’t agree. Some say the pandemic is now endemic – which broadly means the virus and its patterns are predictable and steady in designated regions – and that it’s critical to catch up on health needs neglected during the pandemic, such as screenings and other vaccinations
But others don’t think it’s reached that stage yet, saying that we are letting our guard down too soon and we can’t be blind to the possibility of another strong variant – or pandemic – emerging. Surveillance must continue, not decline, and be improved.
Time to move on?
In its transition roadmap released in February, the HHS notes that daily COVID reported cases are down over 90%, compared with the peak of the Omicron surge at the end of January 2022; deaths have declined by over 80%; and new hospitalizations caused by COVID have dropped by nearly 80%.
It is time to move on, said Ali Mokdad, PhD, a professor and chief strategy officer of population health at the Institute for Health Metrics and Evaluation at the University of Washington, Seattle.
“Many people were delaying a lot of medical care, because they were afraid” during COVID’s height, he said, explaining that elective surgeries were postponed, prenatal care went down, as did screenings for blood pressure and diabetes.
His institute was tracking COVID projections every week but stopped in December.
As for emerging variants, “we haven’t seen a variant that scares us since Omicron” in November 2021, said Dr. Mokdad, who agrees that COVID is endemic now. The subvariants that followed it are very similar, and the current vaccines are working.
“We can move on, but we cannot drop the ball on keeping an eye on the genetic sequencing of the virus,” he said. That will enable quick identification of new variants.
If a worrisome new variant does surface, Dr. Mokdad said, certain locations and resources will be able to gear up quickly, while others won’t be as fast, but overall the United States is in a much better position now.
Amesh Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security, Baltimore, also believes the pandemic phase is behind us
“This can’t be an emergency in perpetuity,” he said “Just because something is not a pandemic [anymore] does not mean that all activities related to it cease.”
COVID is highly unlikely to overwhelm hospitals again, and that was the main reason for the emergency declaration, he said.
“It’s not all or none – collapsing COVID-related [monitoring] activities into the routine monitoring that is done for other infectious disease should be seen as an achievement in taming the virus,” he said.
Not endemic yet
Closing up shop too early could mean we are blindsided, said Rajendram Rajnarayanan, PhD, an assistant dean of research and associate professor at the New York Institute of Technology College of Osteopathic Medicine at Arkansas State University in Jonesboro.
Already, he said, large labs have closed or scaled down as testing demand has declined, and many centers that offered community testing have also closed. Plus, home test results are often not reported.
Continued monitoring is key, he said. “You have to maintain a base level of sequencing for new variants,” he said. “Right now, the variant that is ‘top dog’ in the world is XBB.1.16.”
That’s an Omicron subvariant that the World Health Organization is currently keeping its eye on, according to a media briefing on March 29. There are about 800 sequences of it from 22 countries, mostly India, and it’s been in circulation a few months.
Dr. Rajnarayanan said he’s not overly worried about this variant, but surveillance must continue. His own breakdown of XBB.1.16 found the subvariant in 27 countries, including the United States, as of April 10.
Ideally, Dr. Rajnarayanan would suggest four areas to keep focusing on, moving forward:
- Active, random surveillance for new variants, especially in hot spots.
- Hospital surveillance and surveillance of long-term care, especially in congregate settings where people can more easily spread the virus.
- Travelers’ surveillance, now at , according to the CDC.
- Surveillance of animals such as mink and deer, because these animals can not only pick up the virus, but the virus can mutate in the animals, which could then transmit it back to people.
With less testing, baseline surveillance for new variants has declined. The other three surveillance areas need improvement, too, he said, as the reporting is often delayed.
Continued surveillance is crucial, agreed Katelyn Jetelina, PhD, an epidemiologist and data scientist who publishes a newsletter, Your Local Epidemiologist, updating developments in COVID and other pressing health issues.
“It’s a bit ironic to have a date for the end of a public health emergency; viruses don’t care about calendars,” said Dr. Jetelina, who is also director of population health analytics for the Meadows Mental Health Policy Institute. “COVID-19 is still going to be here, it’s still going to mutate,” and still cause grief for those affected. “I’m most concerned about our ability to track the virus. It’s not clear what surveillance we will still have in the states and around the globe.”
It’s a bit ironic to have a date for the end of a public health emergency; viruses don’t care about calendars.
For surveillance, she calls wastewater monitoring “the lowest-hanging fruit.” That’s because it “is not based on bias testing and has the potential to help with other outbreaks, too.” Hospitalization data is also essential, she said, as that information is the basis for public health decisions on updated vaccines and other protective measures.
While Dr. Jetelina is hopeful that COVID will someday be universally viewed as endemic, with predictable seasonal patterns, “I don’t think we are there yet. We still need to approach this virus with humility; that’s at least what I will continue to do.”
Dr. Rajnarayanan agreed that the pandemic has not yet reached endemic phase, though the situation is much improved. “Our vaccines are still protecting us from severe disease and hospitalization, and [the antiviral drug] Paxlovid is a great tool that works.”
Keeping tabs
While some data tracking has been eliminated, not all has, or will be. The CDC, as mentioned, continues to post cases, deaths, and a daily average of new hospital admissions weekly. The WHO’s dashboard tracks deaths, cases, and vaccine doses globally.
In March, the WHO updated its working definitions and tracking system for SARS-CoV-2 variants of concern and variants of interest, with goals of evaluating the sublineages independently and to classify new variants more clearly when that’s needed.
Still, WHO is considering ending its declaration of COVID as a public health emergency of international concern sometime in 2023.
Some public companies are staying vigilant. The drugstore chain Walgreens said it plans to maintain its COVID-19 Index, which launched in January 2022.
“Data regarding spread of variants is important to our understanding of viral transmission and, as new variants emerge, it will be critical to continue to track this information quickly to predict which communities are most at risk,” Anita Patel, PharmD, vice president of pharmacy services development for Walgreens, said in a statement.
The data also reinforces the importance of vaccinations and testing in helping to stop the spread of COVID-19, she said.

OSHA revisited
Time for my periodic reminder about your Occupational Health and Safety Administration (OSHA) obligations. The health care field still has the most work-related illness and injury reports of any industry in the United States, and OSHA standards are in place to minimize potential workplace incidents.
Even if you hold regular safety meetings (which all too often is not the case), the occasional comprehensive review is always a good idea, and could save you a bundle in fines.
For starters, do you have an official OSHA poster, enumerating employee rights and explaining how to file complaints? Every office must have one posted in plain sight, and it is the first thing an OSHA inspector will look for. You can download one from OSHA’s website or order one at no charge by calling 800-321-OSHA.
The poster discusses the “general standards” that all workplaces must comply with to avoid work-related illnesses and injuries. The standards most applicable to medical offices are those dealing with personal protective equipment (PPE), bloodborne pathogens, hazard communication, and – increasingly, of late – ionizing radiation.
Physicians have become all too familiar with the PPE standard as a result of the COVID pandemic. Ironically, OSHA considers PPE a less acceptable means of employee protection than the other standards, as safe work practices should always supersede safety equipment. Nevertheless, employers must have a PPE program in place to train employees on what equipment is necessary, and under which conditions.
You also need a written exposure control plan for bloodborne pathogens. It should document your use of such protective equipment as gloves, face and eye protection, needle guards, and gowns, and your implementation of universal precautions – and it is supposed to be updated annually, to reflect changes in technology. You must provide all at-risk employees with hepatitis B vaccine at no cost to them. You also must provide and pay for appropriate medical treatment and follow-up after any exposure to a dangerous pathogen.
You need not adopt every new safety device as it comes on the market, but you should document which ones you are using – and which you pass up – and why. For example, you and your employees may decide not to purchase a new safety needle because you don’t think it will improve safety, or that it will be more trouble than it’s worth; but you should document how you arrived at that decision, and why you feel that your current protocol is as good or better.
The hazard communication (or right-to-know) standard involves compiling a list of hazardous substances, which all employees have a right to know about. Keep in mind that OSHA’s list includes alcohol, hydrogen peroxide, acetone, liquid nitrogen, and other substances that you might not consider particularly dangerous, but are nevertheless classified as “hazardous.” For each substance, your employees must have access to the manufacturer-supplied Material Safety Data Sheet, which outlines the proper procedures for working with a specific material, and for handling and containing it in a spill or other emergency.
If your office has x-ray equipment, or you are considering one of the new image-guided superficial radiotherapy machines, you must be in compliance with the ionizing radiation standard, which entails shielding, radiation monitors, and clear labeling of equipment.
Other, more general regulations include the physical setup of your office. Everyone must be able to evacuate quickly in case of fire or other emergencies. At a minimum, you (or the owner of the office building) are expected to establish exit routes to accommodate all employees and to post easily visible evacuation diagrams.
Examine all electrical devices and their power sources. All electrically powered equipment – medical, clerical, or anything else in the office – must operate safely. Pay particular attention to the way wall outlets are set up. Make sure each outlet has sufficient power to run the equipment plugged into it, and that circuit breakers are present and functioning. And beware the common situation of too many gadgets running off a single circuit.
Other components of the rule include proper containment of regulated medical waste, identification of regulated-waste containers, sharps disposal boxes, and periodic employee training regarding all of these things.
Federal OSHA regulations do not require medical and dental offices to keep an injury and illness log, as other businesses must; but your state may have a requirement that supersedes the federal law. Check with your state, or with your local OSHA office, regarding any such requirements.
It is a mistake to take OSHA regulations lightly; failure to comply with them can result in stiff penalties running into many thousands of dollars. How can you be certain you are complying with all the rules? The easiest and cheapest way is to call your local OSHA office and request an inspection. Why would you do that? Because OSHA issues no citations during voluntary inspections as long as you agree to remedy any violations they find.

Time for my periodic reminder about your Occupational Health and Safety Administration (OSHA) obligations. The health care field still has the most work-related illness and injury reports of any industry in the United States, and OSHA standards are in place to minimize potential workplace incidents.
Even if you hold regular safety meetings (which all too often is not the case), the occasional comprehensive review is always a good idea, and could save you a bundle in fines.
For starters, do you have an official OSHA poster, enumerating employee rights and explaining how to file complaints? Every office must have one posted in plain sight, and it is the first thing an OSHA inspector will look for. You can download one from OSHA’s website or order one at no charge by calling 800-321-OSHA.
The poster discusses the “general standards” that all workplaces must comply with to avoid work-related illnesses and injuries. The standards most applicable to medical offices are those dealing with personal protective equipment (PPE), bloodborne pathogens, hazard communication, and – increasingly, of late – ionizing radiation.
Physicians have become all too familiar with the PPE standard as a result of the COVID pandemic. Ironically, OSHA considers PPE a less acceptable means of employee protection than the other standards, as safe work practices should always supersede safety equipment. Nevertheless, employers must have a PPE program in place to train employees on what equipment is necessary, and under which conditions.
You also need a written exposure control plan for bloodborne pathogens. It should document your use of such protective equipment as gloves, face and eye protection, needle guards, and gowns, and your implementation of universal precautions – and it is supposed to be updated annually, to reflect changes in technology. You must provide all at-risk employees with hepatitis B vaccine at no cost to them. You also must provide and pay for appropriate medical treatment and follow-up after any exposure to a dangerous pathogen.
You need not adopt every new safety device as it comes on the market, but you should document which ones you are using – and which you pass up – and why. For example, you and your employees may decide not to purchase a new safety needle because you don’t think it will improve safety, or that it will be more trouble than it’s worth; but you should document how you arrived at that decision, and why you feel that your current protocol is as good or better.
The hazard communication (or right-to-know) standard involves compiling a list of hazardous substances, which all employees have a right to know about. Keep in mind that OSHA’s list includes alcohol, hydrogen peroxide, acetone, liquid nitrogen, and other substances that you might not consider particularly dangerous, but are nevertheless classified as “hazardous.” For each substance, your employees must have access to the manufacturer-supplied Material Safety Data Sheet, which outlines the proper procedures for working with a specific material, and for handling and containing it in a spill or other emergency.
If your office has x-ray equipment, or you are considering one of the new image-guided superficial radiotherapy machines, you must be in compliance with the ionizing radiation standard, which entails shielding, radiation monitors, and clear labeling of equipment.
Other, more general regulations include the physical setup of your office. Everyone must be able to evacuate quickly in case of fire or other emergencies. At a minimum, you (or the owner of the office building) are expected to establish exit routes to accommodate all employees and to post easily visible evacuation diagrams.
Examine all electrical devices and their power sources. All electrically powered equipment – medical, clerical, or anything else in the office – must operate safely. Pay particular attention to the way wall outlets are set up. Make sure each outlet has sufficient power to run the equipment plugged into it, and that circuit breakers are present and functioning. And beware the common situation of too many gadgets running off a single circuit.
Other components of the rule include proper containment of regulated medical waste, identification of regulated-waste containers, sharps disposal boxes, and periodic employee training regarding all of these things.
Federal OSHA regulations do not require medical and dental offices to keep an injury and illness log, as other businesses must; but your state may have a requirement that supersedes the federal law. Check with your state, or with your local OSHA office, regarding any such requirements.
It is a mistake to take OSHA regulations lightly; failure to comply with them can result in stiff penalties running into many thousands of dollars. How can you be certain you are complying with all the rules? The easiest and cheapest way is to call your local OSHA office and request an inspection. Why would you do that?

Bergamot
Citrus bergamia (bergamot) is a fruit tree thought to originate in the Mediterranean area; its fruit has been a part of the diet in that region since the early 18th century.1 Bergamot is known to confer antioxidant as well as anti-inflammatory activity, and yields proapoptotic effects in the sebaceous gland.2,3 The plant contains the natural furocoumarin bergapten, which is also known as 5-methoxypsoralen.4
5 In this capacity, bergamot oil has been used for photodynamic therapy of cutaneous conditions such as vitiligo.6 In fact, for several years 5-methoxypsoralen and 8-methoxypsoralen have been used to achieve acceptable clearance rates of psoriasis and vitiligo.7 This column focuses on bergapten, as well as the cutaneous conditions for which bergamot has been shown to have some benefits warranting application or further investigation.
Bergapten
In a 2021 literature review, Liang et al. cited the anti-inflammatory, antimicrobial, anticancer, and other salutary effects associated with bergapten. Based on numerous citations, they also cautioned about the phototoxicity of the compound combined with ultraviolet (UV) light while noting the photoactivation of bergapten for anticancer uses.4
The following year, Quetglas-Llabrés et al. acknowledged, in another literature review, the numerous preclinical and in vitro studies demonstrating the therapeutic activity of bergapten and highlighted clinical trials revealing notable lesion clearance rates of psoriasis or vitiligo imparted by oral or topical bergapten along with UV irradiation. Bergapten was also found to be effective as hypolipemic therapy.5
Anti-inflammatory topical uses
In a 2017 study by Han et al. of 10 essential oils, bergamot was among the investigated oils, all of which exhibited significant anti-proliferative activity in a preinflamed human dermal fibroblast system simulating chronic inflammation. Bergamot was among three essential oils that also suppressed protein molecules involved with inflammation, immune responses, and tissue remodeling, indicating anti-inflammatory and wound healing characteristics.8
More recently, Cristiano et al. reported that ultradeformable nanocarriers containing bergamot essential oil and ammonium glycyrrhizinate were demonstrated in healthy human volunteers to be characterized by the appropriate mean size, size distribution, surface charge, and long-term stability for topical administration. Topical administration on human volunteers also revealed greater activity of the combined agents as compared with a nanosystem loaded only with ammonium glycyrrhizinate. The researchers concluded that this combination of ingredients in ultradeformable vesicles shows potential as topical anti-inflammatory treatment.3
Acne
In a 2020 study using golden hamsters, Sun et al. assessed the effects of the juice and essential oils of bergamot and sweet orange on acne vulgaris engendered by excessive androgen secretion. Among 80 male hamsters randomly divided into 10 groups ranging from low to high doses, all results demonstrated improvement with treatment as seen by decreased growth rates of sebaceous glands, suppressed triglyceride accumulation, lowered inflammatory cytokine release, and apoptosis promotion in sebaceous glands. The authors noted that the essential oils yielded better dose-dependent effects than the juices.2
Psoriasis
In 2019, Perna et al. conducted a literature review on the effects of bergamot essential oil, extract, juice, and polyphenolic fraction on various health metrics. Thirty-one studies (20 involving humans with 1,709 subjects and 11 in rats and mice) were identified. Animal models indicated that bergamot essential oil (10 mg/kg or 20 mg/kg daily for 20 weeks) reduced psoriatic plaques, increased skin collagen content, and fostered hair growth and that bergamot juice (20 mg/kg) diminished proinflammatory cytokines. Human studies showed that bergamot extract and essential oil may reduce blood pressure and improve mental conditions.9
Vitiligo
In 2019, Shaaban et al. prepared elastic nanocarriers (spanlastics) to deliver psoralen-containing bergamot oil along with PUVB with the intention of harnessing melanogenic activity to treat vitiligo. Histopathologic assessment on rat skin was conducted before clinical treatment in patients with vitiligo. The spanlastics were deemed to be of suitable nanosize and deformable, yielding consistent bergamot oil release. The bergamot oil included in the nanocarrier was found to enhance photostability and photodynamic activity, with the researchers concluding that bergamot oil nanospanlastics with psoralen-UVB therapy shows potential as a vitiligo therapy.10
Two years later, Shaaban evaluated bergamot oil formulated in nanostructured lipid carriers as a photosensitizer for photodynamic treatment of vitiligo. The botanical oil was effectively used in the nanostructured lipid carriers with a gel consistency that delivered sustained release of the oil for 24 hours. Preclinical and clinical results in patients were encouraging for the topical photodynamic treatment of vitiligo, with the nanostructured lipid carriers improving the photostability and photodynamic activity of bergamot oil.6
Photoaging, photoprotection, and safety concerns
Three decades ago, an international cooperative study of the photophysical, photomutagenic, and photocarcinogenic characteristics of bergamot oil and the effect of UVA and UVB sunscreens found that UVB and UVA sunscreens at low concentration (0.5%-1%) in perfumes could not inhibit the phototoxicity of bergamot oil on human skin.11
In a 2015 study assessing the impact of 38% bergamot polyphenolic fraction (a highly concentrated Citrus bergamia fruit extract) on UVB-generated photoaging, Nisticò et al. found that the bergamot compound dose-dependently protected HaCaT cells against UVB-caused oxidative stress and photoaging markers. Suggesting that the high-antioxidant bergamot polyphenolic fraction has potential for use in skin care formulations, the researchers added that the extract seems to induce antiproliferative, immune-modulating, and antiaging activity.12In 2022, Alexa et al. performed in vitro tests and found that natural preparations containing bergamot, orange, and clove essential oils do not significantly alter physiological skin parameters and were deemed safe for topical use. An emulsion with bergamot essential oil was also found to reduce the viability of oral squamous cell carcinoma cells.13
Conclusion
As a photosensitizing agent, bergamot has an established role in skin care. Beyond its niche role in treatments for vitiligo and psoriasis, this botanical product appears to show potential as an anti-inflammatory agent as well as an ingredient to combat photoaging and skin cancer. Much more research is needed to elucidate the possible wider benefits of this Mediterranean staple.

Hospital misdiagnoses blood clot as sciatica; must pay millions
according to a story posted on boston.com, the news site of The Boston Globe.
On March 7, 2015, Steven Luppold, at the time a construction worker, went to the emergency department at Lowell General Hospital, in Lowell, Mass. He had a long history of sciatica. The pain often radiated down his left leg. This time, though, his discomfort in his left foot felt different.
At the ED, Mr. Luppold was initially examined by two nurses, who wrote in the patient’s chart that his foot was turning purple and felt cool to the touch. He was next examined by a physician assistant, Charles Loucraft, who made a diagnosis of worsening sciatica and sent the patient home. Court records suggest Mr. Loucraft made this diagnosis without having read the patient’s chart.
Six days later, Mr. Luppold returned to the ED with severe pain – a 9 on a scale of 10, as he reported at the time. Again, he was seen by two nurses, one of whom had examined him the previous week. He was then examined by Carlos Flores, a nurse practitioner, who reiterated the PA’s initial diagnosis of sciatica. Once more, Mr. Luppold was sent home.
Four days later, on March 17, Mr. Luppold placed a call to his primary care physician (PCP), who worked at Lahey Hospital and Medical Center, in Burlington, Mass., about 18 miles south of Lowell.
The PCP administered an ultrasound and diagnosed the patient as having a deep-vein thrombosis and an arterial thrombosis in his left leg. Mr. Luppold was taken immediately to the Lahey Hospital ED. A vascular surgeon ordered a CT scan, which indicated that the tissue in the patient’s left leg was necrotic. The following day, with few options open to them, surgeons amputated the patient’s left leg above the knee.
At some point after the surgery, Mr. Luppold filed a medical malpractice suit that named the PA, NP, and their physician-group employer, Merrimack Valley Emergency Associates, in Lowell. Also named in the suit were the three ED nurses who had examined him.
“Honestly, the reason this happened was because the communication ... in the emergency department between the nurses and providers was nonexistent,” says Robert M. Higgins, a partner at Lubin & Meyer, in Boston, who represented the plaintiff. Had providers ordered “a simple ultrasound” during either of Mr. Luppold’s visits to the ED, Mr. Higgins added, his leg could have been saved.
The jury agreed. It awarded Mr. Luppold $10 million for pain and suffering and another $10 million in compensatory damages.
At press time, there was no word on whether the defendants planned to appeal.
Doctors at risk for providing trans care to minors
Arkansas doctors who “perform a gender transition procedure” for persons younger than 18 years could be in legal jeopardy for well beyond the date of treatment, reports a story in the Arkansas Advocate, among other news sites.
That prospect is the result of a bill signed into law in March by Arkansas Gov. Sarah Huckabee Sanders. Under the law, slated to take effect this summer, a doctor who provides gender-affirming care to a minor can be sued for a period of up to 15 years after that patient turns 18. (Under current state law, plaintiffs must file a med-mal claim within 2 years of an injury.)
A federal judge is considering whether to strike down a similar measure that was signed into law by Gov. Sanders’s predecessor, Asa Hutchinson, in 2021. That statute prohibits doctors from providing or from referring a minor to someone who would provide gender-affirming hormone or puberty blockers. (Minors in the state do not qualify for gender-related surgery.)
Opponents of such care are hopeful that the 2021 statute will survive judicial review. Even if it doesn’t, though, they believe the new med-mal law will have a similar effect: to dissuade Arkansas doctors from treating minors seeking gender-related treatment.
It’s possible that the new law could itself be subject to a court review. But at least one of the bill’s sponsors, Sen. Gary Stubblefield, a Republican member of the Arkansas senate, is cautiously optimistic: “I know what we did was what we thought was best for our children.”
Opponents argue, though, that the new law will end up harming children who identify as transgender.
“You might not understand what it means to be gay or trans or a member of the LGBTQ community,” explained House Minority Leader Tippi McCullough during debate over the bill in the GOP-led chamber. “I get that, but I’m standing here as the only member of that community in the entire General Assembly, a caucus of one, telling you ... [the bill] denies trans kids the most affirming care they may ever receive in their lives, and that’s cruel.”
Appeals court slashes jury award
A Pennsylvania doctor who faced paying a $2.7 million award has had it cut nearly in half by a three-judge Superior Court panel, as a story in the Claims Journal reports.
The underlying case stems from a suit brought by the estate of a man who died in 2018. At the time of his death, he had been diagnosed with advanced prostate cancer and liver cancer. The suit by the family estate was initially centered on the doctor’s alleged negligence in treating the man’s prostate cancer. At some point during the 2021 trial, though, the suit was amended to include a second claim – an allegation that the doctor had also been negligent in treating the patient’s liver cancer, which had been belatedly diagnosed. The doctor’s medical practice was also a named defendant in the suit.
On March 2, 2022, a jury sided with the plaintiffs, awarding them compensatory damages of $1.5 million for the prostate cancer claim and $1.2 million for the liver cancer claim.
The doctor and other defendants appealed, arguing two essential points: first, the liver cancer claim amounted to a new cause of action, one for which they had not been given adequate notice.
Second, and more significantly, plaintiff action relating to this second claim had only begun in earnest on July 6, 2021, when an expert report was first filed with the court. But this filing was nearly a full year beyond the state’s 2-year statute of limitations, which, given the patient’s death in 2018, was at the very limit, said defendants. For these reasons, they argued, the appeals court should forthwith order a new trial.
That court, however, ended up walking a middle road. Although the court found that the liver claim was “time-barred,” since it had exceeded the 2-year statute of limitations, the court denied the defendants’ motion for a new trial.
Instead, the court cut $1.2 million from the portion of the jury award that applied to the liver cancer claim but left intact the $1.5 million that related to the cause of action regarding prostate cancer.
It was a Solomonic decision that undoubtedly displeased both sides equally.

according to a story posted on boston.com, the news site of The Boston Globe.
On March 7, 2015, Steven Luppold, at the time a construction worker, went to the emergency department at Lowell General Hospital, in Lowell, Mass. He had a long history of sciatica. The pain often radiated down his left leg. This time, though, his discomfort in his left foot felt different.
At the ED, Mr. Luppold was initially examined by two nurses, who wrote in the patient’s chart that his foot was turning purple and felt cool to the touch. He was next examined by a physician assistant, Charles Loucraft, who made a diagnosis of worsening sciatica and sent the patient home. Court records suggest Mr. Loucraft made this diagnosis without having read the patient’s chart.
Six days later, Mr. Luppold returned to the ED with severe pain – a 9 on a scale of 10, as he reported at the time. Again, he was seen by two nurses, one of whom had examined him the previous week. He was then examined by Carlos Flores, a nurse practitioner, who reiterated the PA’s initial diagnosis of sciatica. Once more, Mr. Luppold was sent home.
Four days later, on March 17, Mr. Luppold placed a call to his primary care physician (PCP), who worked at Lahey Hospital and Medical Center, in Burlington, Mass., about 18 miles south of Lowell.
The PCP administered an ultrasound and diagnosed the patient as having a deep-vein thrombosis and an arterial thrombosis in his left leg. Mr. Luppold was taken immediately to the Lahey Hospital ED. A vascular surgeon ordered a CT scan, which indicated that the tissue in the patient’s left leg was necrotic. The following day, with few options open to them, surgeons amputated the patient’s left leg above the knee.
At some point after the surgery, Mr. Luppold filed a medical malpractice suit that named the PA, NP, and their physician-group employer, Merrimack Valley Emergency Associates, in Lowell. Also named in the suit were the three ED nurses who had examined him.
“Honestly, the reason this happened was because the communication ... in the emergency department between the nurses and providers was nonexistent,” says Robert M. Higgins, a partner at Lubin & Meyer, in Boston, who represented the plaintiff. Had providers ordered “a simple ultrasound” during either of Mr. Luppold’s visits to the ED, Mr. Higgins added, his leg could have been saved.
The jury agreed. It awarded Mr. Luppold $10 million for pain and suffering and another $10 million in compensatory damages.

2023 GOLD update: Changes in COPD nomenclature and initial therapy
AIRWAYS DISORDERS NETWORK
Asthma & COPD Section
The 2023 GOLD committee proposed changes in nomenclature and therapy for various subgroups of patients with COPD. The 2023 GOLD committee changed the ABCD group classification to ABE (for exacerbations), which highlights the importance of the number and severity of exacerbations irrespective of daily symptoms.
For patients with features of concomitant asthma or eosinophils greater than or equal to 300 cells/microliter, an ICS/LABA/LAMA combination inhaler is recommended.
People with “young COPD” develop respiratory symptoms and meet spirometric criteria for COPD between the ages of 25 and 50 years old. Other terminology changes center around those with functional and/or structural changes suggesting COPD, but who do not meet the post-bronchodilator spirometric criteria to confirm the COPD diagnosis.
Those with “pre-COPD” have normal spirometry, including the FEV1 and FEV1/FVC ratio, but have functional and/or structural changes concerning for COPD. Functional changes include air trapping and/or hyperinflation on PFTs, low diffusion capacity, and/or decline in FEV1 of >40 mL per year.
Structural changes include emphysematous changes and/or bronchial wall changes on CT scans. “PRISm” stands for preserved ratio with impaired spirometry, where the postbronchodilator FEV1/FVC is greater than or equal to 0.70, but FEV1 is < 80% predicted with similar functional and/or structural changes to those with “pre-COPD.” People with PRISm have increased all-cause mortality. Not all people with pre-COPD or PRISm progress clinically and spiro-metrically to COPD; however, they should be treated because they have symptoms as well as functional and/or structural abnormalities. Despite increasing data regarding pre-COPD and PRISm, many gaps remain regarding optimal management.

Exercise or neuromuscular stimulation in type 2 diabetes?
Studies indicate that physical activity improves glucose metabolism in patients with type 2 diabetes. In addition, other data suggest a decrease in cardiovascular morbidity and mortality through physical activity.
In the consensus report “Management of Hyperglycemia in Type 2 Diabetes, 2022,” the American Diabetes Association and the European Association for the Study of Diabetes, therefore, recommend at least 150 minutes per week of moderate- to vigorous-intensity aerobic activity, supplemented with two to three resistance, flexibility, or balance training sessions per week.
But even when such recommendations are integrated into a therapeutic education program, adherence is often transient or partial.
In this context, Michael Joubert, MD, PhD, and his team at Caen (France) University Hospital wondered about neuromuscular electrical stimulation (NMES), a physical treatment routinely used in functional rehabilitation to improve muscle strength and volume.
To answer this question, they conducted a crossover randomized controlled trial called ELECTRODIAB2. The results were presented at the 2023 Congress of the Francophone Diabetes Society.
A few small pilot studies found that NMES improved insulin sensitivity and glycemic control; therefore, it could indeed be an alternative. The metabolic effect of NMES, however, has not been widely studied.
A total of 40 patients were enrolled in ELECTRODIAB2. Of these participants, 35 were randomly assigned to one of three groups: 6 weeks without NMES (control, no intervention), electrostimulation on 3 days per week for 6 weeks (20-minute ambulatory biquadricipital electrostimulation sessions) (NMES3), and electrostimulation on 5 days per week for 6 weeks (20-minutes ambulatory biquadricipital electrostimulation sessions) (NMES5). The goal was to assess the glucose levels of sedentary patients with type 2 diabetes during these periods. At each session, NMES was applied at the maximum-tolerated intensity.
Data from 32 participants were analyzed. Mean age was 58 ± 10 years, and body mass index was 33.0 ± 4.3 kg/m2. Duration of diabetes was 8.6 ± 5.9 years. Regarding diabetes treatments, 47%, 31%, 9%, and 13% of the patients were taking 0, 1, 2, and 3 oral hypoglycemic agents or glucagonlike peptide–1 agonists, respectively.
No significant differences in glucose levels were observed between the three groups. The primary outcome was mean glucose level based on a 6-day continuous glucose monitoring (CGM) recording. Those levels were 181.4 ± 42.5 mg/dL (control, no intervention), 180.6 ± 45.8 mg/dL (NMES3), and 181.1 ± 48.9 mg/dL (NMES5).
Furthermore, secondary outcomes (rates of hyperglycemia and hypoglycemia) did not differ between the three groups.
The researchers concluded that, “with regard to the CGM criteria, this crossover randomized controlled trial did not show that the 6-week biquadricipital NMES sessions had any benefit. This finding conflicts with the results of preliminary pilot studies but it does not encourage further research on NMES in this population of patients with early-stage diabetes.”
Therefore, at this point, it does not look like NMES can be recommended as an alternative to physical activity for sedentary patients with type 2 diabetes.

That’s ... kind of scary.
Certainly, computers aren’t bad things. In 2023 America you can’t practice medicine without them. They aren’t malicious. They can analyze a lot of data faster than we can (for the record, the average memory capacity of a human brain is 1 petabyte, so we’re still ahead of the average desktop in that regard).
Computers, though, are pretty uniform. I’m a Mac person, and I can go into any Apple store and buy one. Right off the shelf I know how to work it, how it will run a given program, and can predict how it will handle different commands and such. They’re pretty much the same.
People are not quite as easy. Anatomically and chemically we’re similar, but that’s not the same. There are immune, genetic, and multiple other factors that put a lot of variables into the equation. Part of our training is knowing that and taking it into account when making treatment plans.
Algorithms, and artificial intelligence, can only do so much of that. If they were right all the time sports betting wouldn’t exist. But it does, because sports depends on the participants, who are people (or horses), and they’re not exactly alike ... for that matter how they’ll perform varies from day to day for the same individual.
But medical care isn’t a sport (even though hospital call can seem like a marathon). The data we give computers to use is generally based on averages – a rehab stay of 16.6 days for an 85-year-old woman with a broken shoulder (per the above article). But they don’t realize that averages are actually a collection of data on a bell-shaped curve. An insurance company will be only too happy when one person completes their rehabilitation in 11.6 days, and then feel it’s unreasonable when another takes 21.6.
That said, many of the companies involved say the final decisions are made by humans and that the algorithms are just guidelines.
Maybe so, but the STAT article suggests they’re putting too much credence in what the computer says, and not the specific circumstances of the individual involved.
That ain’t good, at least not for the patients.
Medicine, for better or worse, is a business. In an ideal world it probably wouldn’t be, but we don’t live in one.
But it’s unlike any other business out there, and shouldn’t be run like one. A car repair shop knows what parts to order and generally how long repairs will take. Once they’re done the car should be ready to roll out of the shop.
People aren’t like that.
I understand the need to prevent abuse and overbilling for unnecessary days and services. Medicine, unfortunately, has plenty of opportunities for the dishonest to take advantage of.
It’s a thin line, but, at least today, turning treatment decisions over to algorithms and computers is a bad idea for the people we’re supposed to be caring for.
