Florida is seeing a spike in deadly infections caused by the “flesh-eating” bacteria Vibrio vulnificus following Hurricane Ian. 

At least 4 people have died and 29 have been infected in Lee County after the hurricane, Florida health officials said in a news release. 

Vibrio vulnificus bacteria is found in warm, brackish seawater, according to the Florida Department of Health. Anyone with open wounds or cuts should avoid standing water, floodwater, or seawater in the area, health officials said. 

“Sewage spills in coastal waters, like those caused by Hurricane Ian, may increase bacteria levels,” the department advised in a news release. “People with open wounds, cuts, or scratches can be exposed to Vibrio vulnificus through direct contact with sea water or brackish water … Vibrio vulnificus can also cause disease in those who eat raw or undercooked oysters and shellfish.”

Infection can cause severe illness or death. Symptoms include fever, chills, decreased blood pressure, and blistering skin lesions. The bacteria does not spread person to person.

“If someone is concerned that they may have been exposed to Vibrio vulnificus and are experiencing the above symptoms, they should seek medical attention immediately,” officials said in the statement.  “Individuals with wound infections should also seek care promptly.”

Women with psoriatic arthritis (PsA) experience a higher disease burden than that of men with regard to pain, disability, and quality of life, based on data from a cross-sectional survey of more than 2,000 individuals and their rheumatologists and dermatologists.

Although PsA affects men and women in equal numbers, previous research suggests differences in clinical manifestations based on gender that may manifest in many ways, including quality of life, but data on sex differences in PsA are limited, wrote Laure Gossec, MD, of the Pitié-Salpêtrière Hospital and Sorbonne University, Paris, and colleagues.

In a study published in The Journal of Rheumatology, the researchers conducted a cross-sectional survey of rheumatologists and dermatologists and their patients with PsA during June-August 2018. The study population included 2,270 adults from France, Germany, Italy, Spain, the United Kingdom, and the United States. The mean age of the patients was 48.6 years, the mean duration of disease was 4.9 years, and 46% (1,047 patients) were women.

The survey data included information on demographics, treatment, and clinical characteristics, such as tender and swollen joint counts and body surface area affected by psoriasis. The researchers assessed quality of life on the survey using the EuroQoL 5-Dimension questionnaire (EQ-5D) and the impact of disease using the 12-item Psoriatic Arthritis Impact of Disease (PsAID12). They assessed patients’ disability and work productivity using the Health Assessment Questionnaire–Disability Index (HAQ-DI) and Work Productivity and Impairment questionnaire (WPAI).

Overall disease presentation, duration, and use of biologics were similar between men and women. However, women reported significantly worse quality of life compared with men, with a mean EQ-5D score of 0.80 vs. 0.82 (P = .02).

Women also scored higher than men on measures of disability and work impairment, with mean HAQ-DI scores of 0.56 vs. 0.41 and mean WPAI scores of 27.9% vs. 24.6%, respectively (P < .01).

Disease burden was significantly higher in women vs. men based on PsAID12 scores (2.66 vs. 2.27, respectively) and women reported significantly higher levels of fatigue and pain (P < .01 for all).

More men than women reported working full-time (68.6% vs. 49.4%) but no gender differences emerged for work time missed because of PsA, the researchers noted.

However, women had significantly fewer comorbidities compared with men, based on the Charlson Comorbidity Index (1.10 vs. 1.15, P < .01).

“Other factors not assessed in the study are likely to be contributing to disease burden, and these unmeasured factors may affect men and women differently,” the researchers wrote in their discussion. These factors may include hormone levels and treatment outcomes, as well as sleep disturbance, anxiety, and joint erosion, they said.

The study findings were limited by several factors, including the possible overrepresentation of patients who visited physicians more often, the use of self-reports, and potential recall bias, as well as the lack of data on fibromyalgia prevalence using a validated score, the researchers noted. However, the results were strengthened by the large and geographically diverse study population and highlight the need for more research to examine the additional disease burden of PsA in women, and the potential of alternative treatment regimens to improve management of PsA in women, they concluded.
 

Mechanisms driving sex differences remain unclear

“In the past few decades, there has been increasing interest in the effect of sex on the manifestations and impact of PsA as well as on the response to therapy,” Dafna D. Gladman, MD, of the University of Toronto and the Krembil Research Institute at Toronto Western Hospital, wrote in an accompanying editorial.

The current study findings support previous research showing differences in disease expression in PsA between men and women, Dr. Gladman said. Several studies have shown more axial disease and joint damage in men than in women, while women reported greater functional disability and worse quality of life than men. The reasons for gender differences remain unclear, and genetics may play a role as well, she said.

Dr. Gladman emphasized the need for more research on the impact of fibromyalgia (FM) in particular. “As was shown in a previous study, the presence of FM affects the clinical assessment of patients with PsA,” she wrote. Fibromyalgia and pain reporting also may affect clinical trials of patients with PsA; however, the effect of fibromyalgia on sex differences is uncertain, she said. “In a disease that affects men and women equally, recognizing sex effect is important,” and more research is needed to explore the mechanisms behind this effect, she concluded.

The study was supported by Janssen Research & Development. Dr. Gossec disclosed receiving research grants and/or consulting fees from Janssen and 13 other pharmaceutical companies. Several study coauthors disclosed relationships with multiple companies, and several coauthors are employees and stockholders of Janssen. Dr. Gladman had no financial conflicts to disclose.

WASHINGTON – In the 25 years since the United States first launched its universal vaccinations program to protect children against chickenpox (varicella), the program has seen dramatic results, a data analysis indicates.

Results from 1995 – when universal vaccinations began – through 2019 were presented an annual scientific meeting on infectious diseases by Mona Marin, MD, a medical epidemiologist at the Centers for Disease Control and Prevention. Researchers analyzed published data and surveillance data reported to the CDC.
 

Deaths in under-20 group all but eliminated

It’s now rare for children to be hospitalized with chickenpox, and deaths from the infection in people younger than 20 have largely been eliminated. But benefits extend even further.

Immunocompromised people or pregnant women and infants too young to be vaccinated also benefited from the children’s immunizations.

Each year, about 3.8 million cases, 10,500 hospitalizations, and 100 deaths from chickenpox are prevented in the United States thanks to the vaccination program, Dr. Marin said.

Over 25 years, 91 million cases, 238,000 hospitalizations, and 1,933 – 2,446 deaths have been prevented.

However, chickenpox is still widespread in most of the world.
 

U.S. first with universal program

The disease was thought to be of little consequence, Dr. Marin said, until the mid-1950s after the first cases of fatal varicella in immunocompromised children revealed the virus’ lethal potential.

The United States was the first country to introduce a universal vaccination program, Dr. Marin said. At the time, it was a one-dose vaccine. Within the first 10 years of the one-dose program, declines in chickenpox cases, hospitalization, and death rates went from 71% to 90% in comparison with previous years. But health care leaders wanted to close the remaining gap and target transmission in schools.

“It was a burden the United States considered unacceptable,” Dr. Marin said.

The leaders had seen the control of measles and polio and wanted the same for chickenpox.
 

Two-dose vaccines started in 2007

In 2007, the current two-dose policy was introduced. Administration of the first dose is recommended at age 12–15 months, and the second at age 4–6 years. Vaccination is required before the children enter kindergarten.

Coverage was high – at least 90% – the study authors reported; the two-dose program further reduced the number, size, and duration of outbreaks. Over the 25 years, the proportion of outbreaks with fewer than 10 cases increased from 28% to 73%.

By 2019, incidence had dropped by 97%, hospitalizations were down by 94%, and deaths had dropped by 97%.

The biggest decline was seen in those younger than 20, who were born during the vaccination program. That group saw declines of 97% to 99% in cases, hospitalizations, and incidence compared with rates before vaccinations.

Dr. Marin says one dose of the vaccine is moderately effective in preventing all varicella (82%) and is highly effective in preventing severe varicella (more than 97%).

“The second dose adds 10% or more improved protection against all varicella,” she said.

But there have been gains beyond medical advances.

Researchers calculated the economic benefit and found a net savings of $23 billion in medical costs (which also factored in lost wages from parents staying home to care for sick children).
 

Jaw-dropping results

Jeanne Marrazzo, MD, director of the division of infectious diseases at the University of Alabama at Birmingham, said in an interview that “as someone who is not a vaccinologist, the declines in deaths, let alone hospitalizations, were jaw-dropping. I hadn’t really seen a synthesis of the impact of one and two doses.”

She said the declines in zoster among young people were interesting. The big question, she said, is what impact this may have for shingles infections in middle-aged adults over time, since chickenpox and shingles are caused by the same virus.

Dr. Marrazzo also noted the economic savings calculations.

“It’s such a cheap intervention. It’s one of the best examples of how a simple vaccine can affect a cascade of events that are a result of chronic viral infection,” she said.

There are also messages for the current debates over COVID-19 vaccinations.

“For me, it is further evidence of the profound population-level effect safe vaccines can have,” Dr. Marrazzo said.

The authors and Dr. Marrazzo report no relevant financial relationships.

Three months after the World Health Organization declared monkeypox a public health emergency, clinical presentations and vaccination strategies are evolving.

New areas of concern include transmissions among people experiencing homelessness and severe cases in immunocompromised persons.

Agam K. Rao, MD, with the Poxvirus and Rabies Branch of the Centers for Disease Control and Prevention, updated the global picture during an annual scientific meeting on infectious diseases: As of Oct. 14, the confirmed worldwide cases number 73,288, with more than one-third of them (27,317) in the United States. Case counts in the United States, however, have been decreasing since early August.

Cases have been most commonly found in men who have sex with men (MSM), though monkeypox has also been diagnosed in cisgender and transgender women, children, and men who do not report recent sex with other men.

Shift away from White men

Dr. Rao described a demographic shift in infections from White, non-Hispanic men early on to non-Hispanic Black and Hispanic men.

“There’s a lot of emphasis right now at CDC to try to understand these spreads, whether they are household [transmission] or another contact. We know that some of the women have had sexual contact with men who were diagnosed with monkeypox,” Dr. Rao said.

In children under age 12, direct skin-to-skin contact with household members seems to be the source, she said. In adolescents, as in adults, the main source seems to be male-male consensual sex.

“And just as in adults, Black and Hispanic children have been disproportionately affected,” she said.

No sustained spread outside MSM

Dr. Rao said that so far there has been no sustained spread detected beyond the MSM community. A CDC study of inmates in Cook County Jail in Chicago at the end of September, she noted, found no secondary cases.

However, health care workers are another group that was suspected to be at higher risk given close contact with patients, although there have been only three confirmed exposures. Sharps injuries from unroofed lesions are tied to some of those confirmed or suspected cases.

“We do not recommend unroofing lesions,” she said. “We’re getting very good samples from just rigorous swabbing of the lesions.”

She said that the CDC is also monitoring “a few hundred” cases, some of them severe, among people experiencing homelessness.

“We are working to try to understand the exposures that have occurred to those individuals and whether transmission has occurred person-to-person,” Dr. Rao said.

Severe cases among immunocompromised

Also of concern are people with compromised immune systems owing to advanced HIV or organ or stem cell transplants.

Among immunocompromised persons, Dr. Rao said, “we’re seeing large necrotic lesions affecting a large percentage of body surface, lesions that continue to develop over weeks.”

Boghuma Titanji, MD, PhD, MSc, a physician-scientist at Emory University in Atlanta, and an emerging-disease specialist, addressed the difference in presentations between immunocompromised and immunocompetent patients.

She said the main distinction is the extent of the lesions. Patients with AIDS and very low CD4 counts, for instance, are presenting with more lesions and have a longer course of illness.

Dr. Rao said in an interview, “It’s really important to understand someone’s immune status and understand whether they are severely immunocompromised. If there is a concern that a person has monkeypox, also testing for HIV concurrently may be important. It could be a missed opportunity to evaluate for it, especially given the fact that these can occur together.”

Assessing the size and appearance of the lesions is important to understanding whether patients could develop severe infection, she said.

Differences from past epidemics

Dr. Titanji said the current outbreak has some differences from historic outbreaks.

The incubation period, for instance, has tended to be shorter than in previous outbreaks – now 7-10 days, with a range of 5-14 days instead of a range of up to 21 days in previous outbreaks.

There are also more cases of presentations with only single lesions, which were infrequent in past epidemics, she said.

The scope of suspected cases has also broadened, with changing clinical features.

“We have expanded the clinical descriptions to include presentations that involve isolated rectal presentation – individuals presenting solely with rectal pain as the primary manifestation of monkeypox – or presenting with a sore throat as the only manifestation,” she said.

Expanding the case definition will help identify who should be tested.

“Monkeypox is an incredible clinical mimic,” Dr. Titanji said. “The rash can really take the form of a lot of the things we encounter on a regular basis in ID. It’s important to always have a low index of suspicion to test patients when they fit the right epidemiological profile.”

Vaccine strategy has evolved

Brett Petersen, MD, MPH, captain of the U.S. Public Health Service with the CDC, said that Jynneos, licensed by the U.S. Food and Drug Administration, continues to be the primary vaccine for monkeypox. However, the strategy has changed.

Whereas the initial vaccine strategy was to administer the vaccine after known exposure, the guidance now includes vaccinating after “both known and presumed exposures, as described in the eligible populations.”

It’s now been expanded even further to include preexposure inoculations for a wide group of people at greater risk, he explained.

Early data from the CDC indicate that the Jynneos vaccine is effective.

In a report updated in September, the CDC found that among 32 U.S. jurisdictions, monkeypox incidence was much higher among at-risk, unvaccinated people for whom vaccination is recommended than among those who got the Jynneos vaccine.

“Unvaccinated people had 14 times the risk of monkeypox disease compared to people who were vaccinated,” the CDC reported.

Asked about the end goal for monkeypox, Dr. Petersen said, “Our goal should be elimination. I think that is an achievable goal, but it will depend on a lot of factors and a lot of continued public health efforts.”

Dr. Rao, Dr. Titanji, and Dr. Petersen declared no relevant financial relationships.

Three months after the World Health Organization declared monkeypox a public health emergency, clinical presentations and vaccination strategies are evolving.

New areas of concern include transmissions among people experiencing homelessness and severe cases in immunocompromised persons.

Agam K. Rao, MD, with the Poxvirus and Rabies Branch of the Centers for Disease Control and Prevention, updated the global picture during an annual scientific meeting on infectious diseases: As of Oct. 14, the confirmed worldwide cases number 73,288, with more than one-third of them (27,317) in the United States. Case counts in the United States, however, have been decreasing since early August.

Cases have been most commonly found in men who have sex with men (MSM), though monkeypox has also been diagnosed in cisgender and transgender women, children, and men who do not report recent sex with other men.

Shift away from White men

Dr. Rao described a demographic shift in infections from White, non-Hispanic men early on to non-Hispanic Black and Hispanic men.

“There’s a lot of emphasis right now at CDC to try to understand these spreads, whether they are household [transmission] or another contact. We know that some of the women have had sexual contact with men who were diagnosed with monkeypox,” Dr. Rao said.

In children under age 12, direct skin-to-skin contact with household members seems to be the source, she said. In adolescents, as in adults, the main source seems to be male-male consensual sex.

“And just as in adults, Black and Hispanic children have been disproportionately affected,” she said.

No sustained spread outside MSM

Dr. Rao said that so far there has been no sustained spread detected beyond the MSM community. A CDC study of inmates in Cook County Jail in Chicago at the end of September, she noted, found no secondary cases.

However, health care workers are another group that was suspected to be at higher risk given close contact with patients, although there have been only three confirmed exposures. Sharps injuries from unroofed lesions are tied to some of those confirmed or suspected cases.

“We do not recommend unroofing lesions,” she said. “We’re getting very good samples from just rigorous swabbing of the lesions.”

She said that the CDC is also monitoring “a few hundred” cases, some of them severe, among people experiencing homelessness.

MONTREAL – Systemic treatment of atopic dermatitis (AD) boosts mood in addition to relieving skin symptoms, according to a prospective, real-world, clinical cohort study presented at the annual meeting of the International Society of Atopic Dermatitis.

“Randomized, controlled, phase 3 studies have shown that systemic treatment of AD reduces depressive symptoms, but whether this holds true in real-world cohorts remains to be shown,” said study investigator Lina Ivert, MD, PhD, of the dermatology and venereology unit in the department of medicine at the Karolinska Institutet, Stockholm.

The study used data from SwedAD, a newly launched web-based Swedish national registry of patients with AD on systemic treatment between June 2017 and August 2021. Participants were followed at 6 and 12 months for the primary outcome of depressive symptoms using the Montgomery–Åsberg Depression Rating Scale–self-report (MADRS-S). Secondary outcomes included the Eczema Area and Severity Index (EASI) score, Patient-Oriented Eczema Measure (POEM), the Dermatology Life Quality Index (DLQI), and pruritus visual analog scale/numeric rating scale (VAS/NRS).

At baseline, 120 patients (median age, 39 years; 57.5% men) were started on dupilumab (n = 91), methotrexate (26), or cyclosporin (3). Although almost half had no depression at baseline, mild depression was present in 29.2%, with moderate and severe depression in 20% and 4.2%, respectively.

Among 59 patients with 6-month follow-up data (48 on dupilumab, 10 on methotrexate, 1 on cyclosporin), all nine depressive symptoms in MADRS-S improved significantly, with reduced sleep improving the most (from a median of 3 points to a median of 1 point). Similarly, overall MADRS-S scores improved (from a median of 14 points to a median of 5; P < .001), as did EASI scores (from a median of 20.5 to 2), POEM scores (from a median of 22 to 6), DLQI (from a median of 15 to 3), and pruritus scores (from a median of 7.1 to 1.8; all P < .001).

The analysis also found a strong correlation between the MADRS-S score and all of the secondary outcomes (P < .001 for all). All these improvements remained significant among the 36 patients with 12-month follow-up data.

“The median MADRS-S reduction also remained when we excluded eight patients who were on antidepressants during the study period, so these results cannot be explained by psychiatric medication,” noted Dr. Ivert, adding that three patients with severe suicide ideation at baseline improved their MADRS-S suicide item to less than 2 points. “So, this study taught us to look at the suicide item score and not only the total MADRS-S score,” she commented.

Comparing patients treated with dupilumab with those treated with methotrexate, the analysis showed that though baseline median MADRS-S scores did not differ significantly between them, there was a significant 6-month reduction in the dupilumab group but not in the methotrexate group.

Asked to comment on the findings, moderator Marissa Joseph, MD, a pediatric dermatologist at the University of Toronto, said that “the mental health effects of inflammatory skin conditions like atopic dermatitis are well known, but whether or not they are well explored in the patient-physician interaction is a whole other scenario.” There are time constraints, she said, adding, “it sometimes takes some deep-diving ... but exploring those types of symptoms is something we need to do more of, and the severity of the disease and reasons for treatment are not just what you can see.”

Clarissa Ghazi gets lye relaxers, which contain the chemical sodium hydroxide, applied to her hair two to three times a year.

A recent study that made headlines over a potential link between hair straighteners and uterine cancer is not going to make her stop.

“This study is not enough to cause me to say I’ll stay away from this because [the researchers] don’t prove that using relaxers causes cancer,” Ms. Ghazi said.

Indeed, primary care doctors are unlikely to address the increased risk of uterine cancer in women who frequently use hair straighteners that the study reported.

Among frequent users of hair straighteners – meaning those who used them more than four times a year – the researchers found that women were 2.55 times more likely to be diagnosed with uterine cancer than those who never used these products.

In the recently published paper on this research, the authors said that they found an 80% higher adjusted risk of uterine cancer among women who had ever “straightened,” “relaxed,” or used “hair pressing products” in the 12 months before enrolling in their study.

This finding is “real, but small,” says internist Douglas S. Paauw, MD, professor of medicine at the University of Washington in Seattle.

Dr. Paauw is among several primary care doctors interviewed for this story who expressed little concern about the implications of this research for their patients.

“Since we have hundreds of things we are supposed to discuss at our 20-minute clinic visits, this would not make the cut,” Dr. Paauw said.

While it’s good to be able to answer questions a patient might ask about this new research, the study does not prove anything, he said.

Alan Nelson, MD, an internist-endocrinologist and former special adviser to the CEO of the American College of Physicians, said while the study is well done, the number of actual cases of uterine cancer found was small.

One of the reasons he would not recommend discussing the study with patients is that the brands of hair products used to straighten hair in the study were not identified.

Alexandra White, PhD, lead author of the study, said participants were simply asked, “In the past 12 months, how frequently have you or someone else straightened or relaxed your hair, or used hair pressing products?”

The terms “straightened,” “relaxed,” and “hair pressing products” were not defined, and “some women may have interpreted the term ‘pressing products’ to mean nonchemical products” such as flat irons, Dr. White, head of the National Institute of Environmental Health Sciences’ Environment and Cancer Epidemiology group, said in an email.

Dermatologist Crystal Aguh, MD, associate professor of dermatology at Johns Hopkins University, Baltimore, tweeted the following advice in light of the new findings: “The overall risk of uterine cancer is quite low so it’s important to remember that. For now, if you want to change your routine, there’s no downside to decreasing your frequency of hair straightening to every 12 weeks or more, as that may lessen your risk.”

She also noted that “styles like relaxer, silk pressing, and keratin treatments should only be done by a professional, as this will decrease the likelihood of hair damage and scalp irritation.

“I also encourage women to look for hair products free of parabens and phthalates (which are generically listed as “fragrance”) on products to minimize exposure to hormone disrupting chemicals.”
 

Not ready to go curly

Ms. Ghazi said she decided to stop using keratin straighteners years ago after she learned they are made with several added ingredients. That includes the chemical formaldehyde, a known carcinogen, according to the American Cancer Society.

“People have been relaxing their hair for a very long time, and I feel more comfortable using [a relaxer] to straighten my hair than any of the others out there,” Ms. Ghazi said.

Janaki Ram, who has had her hair chemically straightened several times, said the findings have not made her worried that straightening will cause her to get uterine cancer specifically, but that they are a reminder that the chemicals in these products could harm her in some other way.

She said the new study findings, her knowledge of the damage straightening causes to hair, and the lengthy amount of time receiving a keratin treatment takes will lead her to reduce the frequency with which she gets her hair straightened.

“Going forward, I will have this done once a year instead of twice a year,” she said.

Dr. White, the author of the paper, said in an interview that the takeaway for consumers is that women who reported frequent use of hair straighteners/relaxers and pressing products were more than twice as likely to go on to develop uterine cancer compared to women who reported no use of these products in the previous year.

“However, uterine cancer is relatively rare, so these increases in risks are small,” she said. “Less frequent use of these products was not as strongly associated with risk, suggesting that decreasing use may be an option to reduce harmful exposure. Black women were the most frequent users of these products and therefore these findings are more relevant for Black women.”

In a statement, Dr. White noted, “We estimated that 1.64% of women who never used hair straighteners would go on to develop uterine cancer by the age of 70; but for frequent users, that risk goes up to 4.05%.”

The findings were based on the Sister Study, which enrolled women living in the United States, including Puerto Rico, between 2003 and 2009. Participants needed to have at least one sister who had been diagnosed with breast cancer, been breast cancer-free themselves, and aged 35-74 years. Women who reported a diagnosis of uterine cancer before enrollment, had an uncertain uterine cancer history, or had a hysterectomy were excluded from the study.

The researchers examined hair product usage and uterine cancer incidence during an 11-year period among 33 ,947 women. The analysis controlled for variables such as age, race, and risk factors. At baseline, participants were asked to complete a questionnaire on hair products use in the previous 12 months.

“One of the original aims of the study was to better understand the environmental and genetic causes of breast cancer, but we are also interested in studying ovarian cancer, uterine cancer, and many other cancers and chronic diseases,” Dr. White said.

Alexandra White, PhD, lead author of the study, said participants were simply asked, “In the past 12 months, how frequently have you or someone else straightened or relaxed your hair, or used hair pressing products?”

The terms “straightened,” “relaxed,” and “hair pressing products” were not defined, and “some women may have interpreted the term ‘pressing products’ to mean nonchemical products” such as flat irons, Dr. White, head of the National Institute of Environmental Health Sciences’ Environment and Cancer Epidemiology group, said in an email.

Dermatologist Crystal Aguh, MD, associate professor of dermatology at Johns Hopkins University, Baltimore, tweeted the following advice in light of the new findings: “The overall risk of uterine cancer is quite low so it’s important to remember that. For now, if you want to change your routine, there’s no downside to decreasing your frequency of hair straightening to every 12 weeks or more, as that may lessen your risk.”

She also noted that “styles like relaxer, silk pressing, and keratin treatments should only be done by a professional, as this will decrease the likelihood of hair damage and scalp irritation.

“I also encourage women to look for hair products free of parabens and phthalates (which are generically listed as “fragrance”) on products to minimize exposure to hormone disrupting chemicals.”
 

Not ready to go curly

Ms. Ghazi said she decided to stop using keratin straighteners years ago after she learned they are made with several added ingredients. That includes the chemical formaldehyde, a known carcinogen, according to the American Cancer Society.

“People have been relaxing their hair for a very long time, and I feel more comfortable using [a relaxer] to straighten my hair than any of the others out there,” Ms. Ghazi said.

Janaki Ram, who has had her hair chemically straightened several times, said the findings have not made her worried that straightening will cause her to get uterine cancer specifically, but that they are a reminder that the chemicals in these products could harm her in some other way.

She said the new study findings, her knowledge of the damage straightening causes to hair, and the lengthy amount of time receiving a keratin treatment takes will lead her to reduce the frequency with which she gets her hair straightened.

“Going forward, I will have this done once a year instead of twice a year,” she said.

Dr. White, the author of the paper, said in an interview that the takeaway for consumers is that women who reported frequent use of hair straighteners/relaxers and pressing products were more than twice as likely to go on to develop uterine cancer compared to women who reported no use of these products in the previous year.

“However, uterine cancer is relatively rare, so these increases in risks are small,” she said. “Less frequent use of these products was not as strongly associated with risk, suggesting that decreasing use may be an option to reduce harmful exposure. Black women were the most frequent users of these products and therefore these findings are more relevant for Black women.”

In a statement, Dr. White noted, “We estimated that 1.64% of women who never used hair straighteners would go on to develop uterine cancer by the age of 70; but for frequent users, that risk goes up to 4.05%.”

The findings were based on the Sister Study, which enrolled women living in the United States, including Puerto Rico, between 2003 and 2009. Participants needed to have at least one sister who had been diagnosed with breast cancer, been breast cancer-free themselves, and aged 35-74 years. Women who reported a diagnosis of uterine cancer before enrollment, had an uncertain uterine cancer history, or had a hysterectomy were excluded from the study.

The researchers examined hair product usage and uterine cancer incidence during an 11-year period among 33 ,947 women. The analysis controlled for variables such as age, race, and risk factors. At baseline, participants were asked to complete a questionnaire on hair products use in the previous 12 months.

“One of the original aims of the study was to better understand the environmental and genetic causes of breast cancer, but we are also interested in studying ovarian cancer, uterine cancer, and many other cancers and chronic diseases,” Dr. White said.

Clarissa Ghazi gets lye relaxers, which contain the chemical sodium hydroxide, applied to her hair two to three times a year.

A recent study that made headlines over a potential link between hair straighteners and uterine cancer is not going to make her stop.

“This study is not enough to cause me to say I’ll stay away from this because [the researchers] don’t prove that using relaxers causes cancer,” Ms. Ghazi said.

Indeed, primary care doctors are unlikely to address the increased risk of uterine cancer in women who frequently use hair straighteners that the study reported.

Among frequent users of hair straighteners – meaning those who used them more than four times a year – the researchers found that women were 2.55 times more likely to be diagnosed with uterine cancer than those who never used these products.

In the recently published paper on this research, the authors said that they found an 80% higher adjusted risk of uterine cancer among women who had ever “straightened,” “relaxed,” or used “hair pressing products” in the 12 months before enrolling in their study.

This finding is “real, but small,” says internist Douglas S. Paauw, MD, professor of medicine at the University of Washington in Seattle.

Dr. Paauw is among several primary care doctors interviewed for this story who expressed little concern about the implications of this research for their patients.

“Since we have hundreds of things we are supposed to discuss at our 20-minute clinic visits, this would not make the cut,” Dr. Paauw said.

While it’s good to be able to answer questions a patient might ask about this new research, the study does not prove anything, he said.

Janus kinase inhibitors tofacitinib (Xeljanz) and baricitinib (Olumiant) may pose no greater risk than does adalimumab (Humira and biosimilars) for major adverse cardiovascular events (MACEs) or venous thromboembolism (VTE) on the basis of a nationwide cohort study.

The French data, which included almost 16,000 patients with rheumatoid arthritis, revealed similar safety across subgroups, including older patients with at least one preexisting cardiovascular risk factor, reported lead author Léa Hoisnard, MD, of Henri Mondor Hospital, Paris, and colleagues.

These findings arrive 1 year after the U.S. Food and Drug Administration imposed class-wide boxed warnings on three Janus kinase (JAK) inhibitors, citing increased risks for both cancer and serious cardiac events detected by the open-label, randomized ORAL Surveillance postmarketing trial, which compared tofacitinib against adalimumab and etanercept.

More recently, the observational STAR-RA study, relying upon private insurance and Medicare claims in the United States, found no significant increase in cardiovascular events among patients taking tofacitinib, adding some uncertainty to the conversation.

“In this context, observational studies of unselected populations outside of North America are still needed to assess other JAK inhibitor agents,” Dr. Hoisnard and colleagues write in Annals of the Rheumatic Diseases.

Their retrospective study included 8,481 patients who received baricitinib or tofacitinib, and 7,354 patients who received adalimumab. Almost all patients in the tofacitinib group received 5 mg twice daily instead of 10 mg twice daily (99.4% vs. 0.6%), so cardiovascular safety was assessed only for the 5-mg dose. Baricitinib was prescribed at 4-mg and 2-mg doses (79.5% vs. 20.5%), allowing inclusion of both dose levels. The investigators accounted for a range of covariates, including concurrent therapy, comorbidities, and other patient characteristics.

Median follow-up durations were 440 days in the JAK inhibitor group and 344 days in the adalimumab group. The JAK inhibitor group had numerically more MACEs than did the adalimumab group, but the difference in risk was not statistically significant (54 vs. 35 MACEs; weighted hazard ratio, 1.0; 95% confidence interval, 0.7-1.5; P = .99). Similarly, more patients taking JAK inhibitors had VTEs, but relative risk was, again, not significant (75 vs. 32 VTEs; HRw, 1.1; 95% CI, 0.7-1.6; P = .63).

These findings were consistent for all subgroups, including patients aged 50 years or older and patients aged 65 years or older, although the investigators noted that statistical power was lacking for subgroup analyses.
 

Findings from Echo ORAL Surveillance

“I think the baricitinib data are important,” Kevin Winthrop, MD, MPH, professor of infectious diseases and epidemiology at Oregon Health & Science University, Portland, told this news organization. “There’s no difference between 2 mg and 4 mg [dose levels] in this analysis. And there doesn’t really seem to be a difference between baricitinib and tofacitinib. Most of the results are pretty consistent with ORAL Surveillance, which was a randomized, controlled trial.”

Dr. Winthrop, who has been active in JAK inhibitor clinical trials, recently coauthored an article in Nature Reviews Rheumatology encouraging clinicians to remember that the cardiovascular risks of JAK inhibitors are relative to adalimumab, and safety should be framed within the context of risk-to-benefit ratios.

He and his coauthor also called into question the FDA’s “better to be safe than sorry” approach, which resulted in boxed warnings across all JAK inhibitors, despite differences in target specificity.

“There are pros and cons of taking that approach,” Dr. Winthrop said in an interview. “The FDA might ultimately be right. Certainly, these drugs appear similar for some types of events, like herpes zoster, for example. But whether they’re similar with regard to malignancy or cardiovascular events, I don’t think we know.”

Dr. Winthrop noted that deucravacitinib was recently approved for psoriasis sans boxed warning, suggesting inconsistency in the FDA’s approach. The agent headlines as a “TYK2 inhibitor,” but TYK2 is a member of the JAK family.

“I don’t know why the FDA decided to treat them differently,” Dr. Winthrop said.

Boxed warnings encourage caution, lock treatment sequence

Michael Thakor, MD, of Arthritis & Rheumatology Clinic of Northern Colorado, Fort Collins, supports the boxed warnings because they encourage caution and transparency.

“It forces you to have that discussion with your patient, which may take some time, but it’s actually a very good thing,” Dr. Thakor said in an interview. “Some patients will say, ‘Oh my gosh, I don’t want to take that drug.’ But most patients, considering the level of risk that you’re talking about, are actually okay going ahead with the medication.”

If these risks aren’t discussed, he noted, patient trust may falter.

“They’re going to go online, and they’re going to be reading about it,” Dr. Thakor said. “And then they tend to get more spooked. They also may question your advice from then on, if you’re not telling them the possible risk.”

Reflecting on the present study, Dr. Thakor said that the findings initially appeared reassuring, but he became concerned about the lack of power and how adverse events trended higher in the JAK inhibitor group, particularly for VTEs, most of which occurred with baricitinib. This latter finding is challenging to interpret, however, because the 4-mg dose is not used in the United States, he added.

Dr. Thakor described how JAK inhibitors once seemed poised to assume a frontline role in RA until the boxed warnings came out. These safety concerns don’t take JAK inhibitors off the table, he said, but they do keep the class further down the treatment sequence, and the present data don’t alter this picture in daily practice.

“If I had a patient who was over the age of 50 with at least one cardiovascular risk factor, I might have a little bit of concern, but if they need their RA treated, I would definitely discuss the possibility of using a JAK inhibitor,” Dr. Thakor said. “If the patient is comfortable with it, then I would feel comfortable going ahead.”

The investigators disclosed no outside funding or conflicts of interest. Dr. Winthrop disclosed relationships with AbbVie, AstraZeneca, Bristol-Myers Squibb, and others. Dr. Thakor disclosed no conflicts of interest.

A new study underscores the importance of COVID-19 and regular COVID-19 testing among adults with a recent cancer diagnosis.

The Indiana statewide study, conducted at the beginning of the pandemic, found that unvaccinated adults with cancer and SARS-CoV-2 infection were nearly seven times more likely to die from any cause than uninfected adults with cancer.

“This analysis provides additional empirical evidence on the magnitude of risk to patients with cancer whose immune systems are often weakened either by the disease or treatment,” the study team wrote.

The study was published online in JMIR Cancer.

Although evidence has consistently revealed similar findings, the risk of death among unvaccinated people with cancer and COVID-19 has not been nearly as high in previous studies, lead author Brian E. Dixon, PhD, MBA, with Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, said in a statement. Previous studies from China, for instance, reported a two- to threefold greater risk of all-cause mortality among unvaccinated adults with cancer and COVID-19.

A potential reason for this discrepancy, Dr. Dixon noted, is that earlier studies were “generally smaller and made calculations based on data from a single cancer center or health system.”

Another reason is testing for COVID-19 early in the pandemic was limited to symptomatic individuals who may have had more severe infections, possibly leading to an overestimate of the association between SARS-CoV-2 infection, cancer, and all-cause mortality.

In the current analysis, researchers used electronic health records linked to Indiana’s statewide SARS-CoV-2 testing database and state vital records to evaluate the association between SARS-CoV-2 infection and all-cause mortality among 41,924 adults newly diagnosed with cancer between Jan. 1, 2019, and Dec. 31, 2020.

Most people with cancer were White (78.4%) and about half were male. At the time of diagnosis, 17% had one comorbid condition and about 10% had two or more. Most patients had breast cancer (14%), prostate cancer (13%), or melanoma (13%).

During the study period, 2,894 patients (7%) tested positive for SARS-CoV-2.

In multivariate adjusted analysis, the risk of death among those newly diagnosed with cancer increased by 91% (adjusted hazard ratio, 1.91) during the first year of the pandemic before vaccines were available, compared with the year before (January 2019 to Jan. 14, 2020).

During the pandemic period, the risk of death was roughly threefold higher among adults 65 years old and older, compared with adults 18-44 years old (aHR, 3.35).

When looking at the time from a cancer diagnosis to SARS-CoV-2 infection, infection was associated with an almost sevenfold increase in all-cause mortality (aHR, 6.91). Adults 65 years old and older had an almost threefold increased risk of dying, compared with their younger peers (aHR, 2.74).

Dr. Dixon and colleagues also observed an increased risk of death in men with cancer and COVID, compared with women (aHR, 1.23) and those with at least two comorbid conditions versus none (aHR, 2.12). In addition, the risk of dying was 9% higher among Indiana’s rural population than urban dwellers.

Compared with other cancer types, individuals with lung cancer and other digestive cancers had the highest risk of death after SARS-CoV-2 infection (aHR, 1.45 and 1.80, respectively).

“Our findings highlight the increased risk of death for adult cancer patients who test positive for COVID and underscore the importance to cancer patients – including those in remission – of vaccinations, boosters, and regular COVID testing,” Dr. Dixon commented.

“Our results should encourage individuals diagnosed with cancer not only to take preventive action, but also to expeditiously seek out treatments available in the marketplace should they test positive for COVID,” he added.

Support for the study was provided by Indiana University Simon Cancer Center and the Centers for Disease Control and Prevention. The authors have disclosed no relevant financial relationships.

The study was published online in JMIR Cancer.

Although evidence has consistently revealed similar findings, the risk of death among unvaccinated people with cancer and COVID-19 has not been nearly as high in previous studies, lead author Brian E. Dixon, PhD, MBA, with Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, said in a statement. Previous studies from China, for instance, reported a two- to threefold greater risk of all-cause mortality among unvaccinated adults with cancer and COVID-19.

A potential reason for this discrepancy, Dr. Dixon noted, is that earlier studies were “generally smaller and made calculations based on data from a single cancer center or health system.”

Another reason is testing for COVID-19 early in the pandemic was limited to symptomatic individuals who may have had more severe infections, possibly leading to an overestimate of the association between SARS-CoV-2 infection, cancer, and all-cause mortality.

In the current analysis, researchers used electronic health records linked to Indiana’s statewide SARS-CoV-2 testing database and state vital records to evaluate the association between SARS-CoV-2 infection and all-cause mortality among 41,924 adults newly diagnosed with cancer between Jan. 1, 2019, and Dec. 31, 2020.

Most people with cancer were White (78.4%) and about half were male. At the time of diagnosis, 17% had one comorbid condition and about 10% had two or more. Most patients had breast cancer (14%), prostate cancer (13%), or melanoma (13%).

During the study period, 2,894 patients (7%) tested positive for SARS-CoV-2.

In multivariate adjusted analysis, the risk of death among those newly diagnosed with cancer increased by 91% (adjusted hazard ratio, 1.91) during the first year of the pandemic before vaccines were available, compared with the year before (January 2019 to Jan. 14, 2020).

During the pandemic period, the risk of death was roughly threefold higher among adults 65 years old and older, compared with adults 18-44 years old (aHR, 3.35).

When looking at the time from a cancer diagnosis to SARS-CoV-2 infection, infection was associated with an almost sevenfold increase in all-cause mortality (aHR, 6.91). Adults 65 years old and older had an almost threefold increased risk of dying, compared with their younger peers (aHR, 2.74).

Dr. Dixon and colleagues also observed an increased risk of death in men with cancer and COVID, compared with women (aHR, 1.23) and those with at least two comorbid conditions versus none (aHR, 2.12). In addition, the risk of dying was 9% higher among Indiana’s rural population than urban dwellers.

Compared with other cancer types, individuals with lung cancer and other digestive cancers had the highest risk of death after SARS-CoV-2 infection (aHR, 1.45 and 1.80, respectively).

“Our findings highlight the increased risk of death for adult cancer patients who test positive for COVID and underscore the importance to cancer patients – including those in remission – of vaccinations, boosters, and regular COVID testing,” Dr. Dixon commented.

“Our results should encourage individuals diagnosed with cancer not only to take preventive action, but also to expeditiously seek out treatments available in the marketplace should they test positive for COVID,” he added.

Support for the study was provided by Indiana University Simon Cancer Center and the Centers for Disease Control and Prevention. The authors have disclosed no relevant financial relationships.

A new study underscores the importance of COVID-19 and regular COVID-19 testing among adults with a recent cancer diagnosis.

Tumor vs. saxophone: The surgical grudge match

Brain surgery is a notoriously difficult task. There’s a reason we say, “Well, at least it’s not brain surgery” when we’re trying to convince someone that a task isn’t that tough. Make one wrong incision, cut the wrong neuron, and it’s goodbye higher cognitive function. And most people appreciate thinking. Crazy, right?

One would imagine that the act of brain surgery would become even more difficult when the patient brings his saxophone and plays it randomly throughout the operation. It’s a hospital, after all, not a jazz club. Patients don’t get to play musical instruments during other surgeries. Why should brain surgery patients get special treatment?

Paideia International Hospital

As it turns out, the musical performance was actually quite helpful. A man in Italy had a brain tumor in a particularly complex area, and he’s left-handed, which apparently makes the brain’s neural pathways much more complicated. Plus, he insisted that he retain his musical ability after the surgery. So he and his medical team had a crazy thought: Why not play the saxophone throughout the surgery? After all, according to head surgeon Christian Brogna, MD, playing an instrument means you understand music, which tests many higher cognitive functions such as coordination, mathematics, and memory.

And so, at various points throughout the 9-hour surgery, the patient played his saxophone for his doctors. Doing so allowed the surgeons to map the patient’s brain in a more complete and personalized fashion. With that extra knowledge, they were able to successfully remove the tumor while maintaining the patient’s musical ability, and the patient was discharged on Oct. 13, just 3 days after his operation.

While we’re happy the patient recovered, we do have to question his choice of music. During the surgery, he played the theme to the 1970 movie “Love Story” and the Italian national anthem. Perfectly fine pieces, no doubt, but the saxophone solo in “Jungleland” exists. And we could listen to that for 9 hours straight. In fact, we do that every Friday in the LOTME office.
 

Basketball has the Big Dance. Mosquitoes get the Big Sniff

In this week’s installment of our seemingly never-ending series, “Mosquitoes and the scientists who love them,” we visit The Rockefeller University in New York, where the olfactory capabilities of Aedes Aegypti – the primary vector species for Zika, dengue, yellow fever, and chikungunya – became the subject of a round robin–style tournament.

First things first, though. If you’re going to test mosquito noses, you have to give them something to smell. The researchers enrolled eight humans who were willing to wear nylon stockings on their forearms for 6 hours a day for multiple days. “Over the next few years, the researchers tested the nylons against each other in all possible pairings,” Leslie B. Vosshall, PhD, and associates said in a statement from the university. In other words, mosquito March Madness.

Nylons from different participants were hooked up in pairs to an olfactometer assay consisting of a plexiglass chamber divided into two tubes, each ending in a box that held a stocking. The mosquitoes were placed in the main chamber and observed as they flew down the tubes toward one stocking or the other.

Eventually, the “winner” of the “tournament” was Subject 33. And no, we don’t know why there was a Subject 33 since the study involved only eight participants. We do know that the nylons worn by Subject 33 were “four times more attractive to the mosquitoes than the next most-attractive study participant, and an astonishing 100 times more appealing than the least attractive, Subject 19,” according to the written statement.

Chemical analysis identified 50 molecular compounds that were elevated in the sebum of the high-attracting participants, and eventually the investigators discovered that mosquito magnets produced carboxylic acids at much higher levels than the less-attractive volunteers.

We could go on about the research team genetically engineering mosquitoes without odor receptors, but we have to save something for later. Tune in again next week for another exciting episode of “Mosquitoes and the scientists who love them.”
 

Are women better with words?

Men vs. Women is probably the oldest argument in the book, but there may now be movement. Researchers have been able not only to shift the advantage toward women, but also to use that knowledge to medical advantage.

When it comes to the matter of words and remembering them, women apparently have men beat. The margin is small, said lead author Marco Hirnstein, PhD, of the University of Bergen, Norway, but, after performing a meta-analysis of 168 published studies and PhD theses involving more than 350,000 participants, it’s pretty clear. The research supports women’s advantage over men in recall, verbal fluency (categorical and phonemic), and recognition.

So how is this information useful from a medical standpoint?

Dr. Hirnstein and colleagues suggested that this information can help in interpreting diagnostic assessment results. The example given was dementia diagnosis. Since women are underdiagnosed because their baseline exceeds average while men are overdiagnosed, taking gender and performance into account could clear up or catch cases that might otherwise slip through the cracks.

Now, let’s just put this part of the debate to rest and take this not only as a win for women but for science as well.

A systematic review was recently conducted by Wu and colleagues examining the risk of blindness associated with platelet-rich plasma (PRP) injection. In dermatology, PRP is used more commonly now than 5 years ago to promote hair growth with injections on the scalp, as an adjunct to microneedling procedures, and sometimes – in a similar way to facial fillers – to improve volume loss, and skin tone and texture (particularly to the tear trough region).

The analysis of four studies revealed seven cases of unilateral blindness or vision impairment associated with PRP injections. All cases were reported after use of PRP as a facial injection, not with PRP scalp injection or with microneedling. Total unilateral blindness occurred in all cases. In one of the seven reported cases, the patient experienced recovery of vision after 3 months, but with some residual deficits noted on the ophthalmologist examination. In this case, the patient was evaluated and treated by an ophthalmologist within 3 hours of symptom onset.

In addition, four cases were reported from Venezuela, one from the United States, one from the United Kingdom, and one from Malaysia. Similar to reports of blindness with facial fillers, the most common injection site reported with this adverse effect was the glabella (five cases);

Other reports involved injections of the forehead (two), followed by the nasolabial fold (one), lateral canthus (one), and temporomandibular joint (one). Two of the seven patients received injections at more than one site, resulting in the total number of injections reported (10) being higher than the number of patients.

The risk of blindness is inherent with deep injection into a vessel that anastomoses with the blood supply to the eye. No mention was made as to whether PRP or platelet-rich fibrin was used. Other details are lacking from the original articles as to injection technique and whether or not cannula injection was used. No treatment was attempted in four of seven cases.

As plasma is native to the arteries and dissolves in the blood stream naturally, the mechanism as to why retinal artery occlusion or blindness would occur is not completely clear. One theory is that it is volume related and results from the speed of injection, causing a large rapid bolus that temporarily occludes or compresses an involved vessel.

Another theory is that damage to the vessel results from the injection itself or injection technique, leading to a clotting cascade and clot of the involved vessel with subsequent retrograde flow or blockade of the retinal artery. But if this were the case, we would expect to hear about more cases of clots leading to vascular occlusion or skin necrosis, which does not typically occur or we do not hear about.

Details about proper collection materials and technique or mixing with some other materials are also unknown in these cases, thus leaving the possibility that a more occlusive material may have been injected, as opposed to the fluid-like composition of the typical PRP preparation.With regards to risk with scalp PRP injection, the frontal scalp does receive blood supply from the supratrochlear artery that anastomoses with the angular artery of the face – both of which anastomose with the retinal artery (where occlusion would occur via back flow). The scalp tributaries are small and far enough away from the retina at that point that risk of back flow the to retinal artery should be minimal. Additionally, no reports of vascular occlusion from PRP scalp injection leading to skin necrosis have ever been reported. Of note, this is also not a risk that has been reported with the use of PRP with microneedling procedures, where PRP is placed on top of the skin before, during and after microneedling.

Anything that occludes the blood supply to the eye, whether it be fat, filler, or PRP, has an inherent risk of blindness. As there is no reversal agent or designated treatment for PRP occlusion, care must be taken to minimize risk, including awareness of anatomy and avoidance of injection into high risk areas, and cannula use where appropriate. Gentle, slow, low-volume administration, and when possible, use of a retrograde injection technique, may also be helpful.

Anything that occludes the blood supply to the eye, whether it be fat, filler, or PRP, has an inherent risk of blindness. As there is no reversal agent or designated treatment for PRP occlusion, care must be taken to minimize risk, including awareness of anatomy and avoidance of injection into high risk areas, and cannula use where appropriate. Gentle, slow, low-volume administration, and when possible, use of a retrograde injection technique, may also be helpful.
