Disease-modifying antirheumatic drugs (DMARDs) such as biologics may carry an increased risk for preterm birth or cesarean delivery for pregnant women with psoriatic arthritis (PsA), according to a recent study published in Arthritis & Rheumatology.

The risk was particularly high for women with PsA who received biologic disease-modifying antirheumatic drugs (bDMARDs), according to Katarina Remaeus, PhD, of the Karolinska Institute in Stockholm and colleagues.

“The results may indicate that a more severe or active PsA disease that requires antirheumatic treatment during pregnancy, especially bDMARDs, is associated with increased risks of adverse pregnancy outcomes compared to non-PsA pregnancies,” Dr. Remaeus and colleagues write in their study. “The risk of preterm birth in PsA pregnancies is further influenced by parity with the most increased risks observed in first pregnancies.”

In a nationwide, register-based cohort study, the researchers evaluated 921 pregnancies of women with PsA between 2007 and 2017, comparing them to the pregnancies of 9,210 women without PsA over the same time frame. The pregnancies for women with PsA were further categorized based on whether the women had not received antirheumatic treatment in the year prior to and/or during pregnancy (495 pregnancies) or had received antirheumatic treatment at any point in the year before and/or during pregnancy (426 pregnancies).

Of the women in the PsA group who were treated in the year prior to pregnancy (170 women), 39.4% received monotherapy with a conventional synthetic DMARD (csDMARD) such as an antimalarial, methotrexate, or sulfasalazine; 24.1% received oral corticosteroids, and 15.9% received a tumor necrosis factor inhibitor (TNFi), whereas about 20% of women received two or more antirheumatic drugs.

In the group of women treated during pregnancy (256 women), 153 did not receive bDMARDs; of these, 41.8% had monotherapy with either a csDMARD or corticosteroids, whereas the group treated with bDMARDs received TNFi monotherapy (43.7%) or TNFi with corticosteroids (35.9%), TNFi with csDMARD (9.7%), or TNFi with csDMARD plus corticosteroids (9.7%).

A majority of women in both groups (70.1%) were between ages 30 and 34 years (37.1%) or older than age 35 years (33%) and had delivered more than one child (63.2%). Women in the PsA group were more likely to be born in a Nordic country (91.8% vs. 82.8%), to have a body mass index between 30.0 and 60.0 kg/m² (19.9% vs. 12.6%), to be a smoker (9.2% vs. 5.3%), to have hypertension (1.4% vs. 0.8%) or diabetes (1.3% vs. 0.5%) prior to pregnancy, and to have a higher level of education (>12 years; 50.1% vs. 43.3%), compared with women in the non-PsA group.

The results showed women in the PsA group were more likely to experience preterm birth (adjusted odds ratio, 1.69; 95% confidence interval, 1.27-2.24) and undergo an elective (aOR, 1.77; 95% CI, 1.43-2.20) or emergency C-section (aOR, 1.42; 95% CI, 1.10-1.84). The group at highest risk for preterm birth with regard to parity was women with PsA having their first child (aOR, 3.95; 95% CI, 1.43-10.95).

Women who received antirheumatic treatment were at greater risk for experiencing preterm birth (aOR, 2.30; 95% CI, 1.49-3.56), and this risk was even higher for treatment with bDMARDs, compared with women without PsA (aOR, 4.49; 95% CI, 2.60-7.79). Use of bDMARDs also was associated with higher risks for spontaneous preterm birth (aOR, 4.73; 95% CI, 2.53-8.87), preterm birth between 32 and 36 weeks’ gestation (aOR, 5.06; 95% CI, 2.91-8.79), elective C-section (aOR, 2.72; 95% CI, 1.61-4.59), emergency C-section (aOR, 2.06; 95% CI, 1.04-4.07), and preeclampsia (aOR, 2.88, 95% CI, 1.35-6.17).

The researchers note that women with PsA should be evaluated for preterm birth particularly if they are having their first child, and “from a clinical point of view, all women with PsA, regardless of antirheumatic treatment, should be counseled about pregnancy outcomes and receive individualized monitoring during pregnancy.”

Are adverse outcomes linked to disease activity or treatment?

Patients in the study had a higher risk of adverse outcomes when they had a PsA diagnosis, and when they received antirheumatic treatment – but were the adverse outcomes associated with a patient’s high disease activity or need for antirheumatic treatment?

“Our interpretation is that a PsA disease that requires continued antirheumatic treatment during pregnancy is more severe than PsA that does not require treatment,” Dr. Remaeus and colleagues write. “Thus, the increased risk of adverse outcomes in pregnancies with maternal antirheumatic treatment is probably attributed to disease severity rather than an effect of the medication itself.”

Anja Strangfeld, MD, PhD, of the German Rheumatism Research Centre in Berlin, told this news organization that the results of the study are important because it is one of the first to report differences in risk in pregnancy outcomes for women with and without PsA.

“The information is relevant to guide rheumatologists in advising patients with PsA when planning the first or subsequent pregnancies,” she said. “The results are reassuring in reporting that the elevated risk for PsA patients for adverse pregnancy outcomes is low in patients not in need of antirheumatic medication, presumably in low-disease activity.”

However, the study is still unclear on whether the association with adverse pregnancy outcomes in patients is the result of higher disease activity or the need for antirheumatic treatment, she explained.

“It was only hypothesized that those patients under bDMARD treatment are/were in high disease activity. There [is] no information on disease activity in the data sources, which limits the results,” she said. “The investigation still does not solve the important question – if adverse pregnancy outcomes are rather related to high disease activity or the medication to treat this situation.”

There was no specific funding for this study. The study authors and Dr. Strangfeld have disclosed no relevant financial relationships.

LAS VEGAS – In the treatment of Helicobacter pylori infection, combination therapies using the oral potassium-competitive acid blocker vonoprazan were superior to standard proton pump inhibitor (PPI)–based triple therapy, producing higher eradication rates, according to combined data from a U.S. and a European phase 3 randomized, controlled trial.

Vonoprazan has been submitted to the Food and Drug Administration for approval with a Fast Track designation in combination with amoxicillin and clarithromycin (triple therapy) or amoxicillin alone (dual therapy) for treating H. pylori infection. It has already been approved in Japan for the treatment of gastric and duodenal ulcers, reflux esophagitis, secondary prevention of low-dose aspirin– or nonsteroidal anti-inflammatory drug–induced gastric mucosal damage, and for first and second-line H. pylori eradication therapy.

Study details

The study included 1,046 treatment-naive patients who had dyspepsia, a recent or new diagnosis of a nonbleeding peptic ulcer, a history of a peptic ulcer, or long-term stable use of an NSAID. Patients were randomized to PPI-based triple therapy (lansoprazole, amoxicillin, clarithromycin), vonoprazan triple therapy (plus amoxicillin, clarithromycin), or vonoprazan dual therapy (amoxicillin). The treatment period was 14 days, followed by 13C urea breath test (UBT) 4 weeks after treatment.

The researchers conducted several analyses, including: Modified intention-to-treat analyses, which included all enrollees; per protocol analyses, which included patients who took at least 75% of each study medication and underwent 13C UBT in the expected time frame; and a safety population of all patients who took at least one study drug.

Among patients with H. pylori strains that were not resistant to clarithromycin, the PPI-based triple-therapy group had an eradication rate of 78.8%, compared with 84.7% in the vonoprazan triple-therapy group (P < .0001), and 78.5% in the vonoprazan dual-therapy group (P = .0037). In the per protocol analysis, PPI-based triple therapy eradicated H. pylori 82.1% of the time, compared with 90.4% in the vonoprazan triple-therapy group (P < .0001) and 81.2% in the vonoprazan dual-therapy group (P = .0077). Both vonoprazan treatment groups were noninferior to PPI-based triple therapy.

A prespecified exploratory analysis found that vonoprazan triple therapy outperformed PPI-based triple therapy in the modified intention-to-treat population (P = .0408) and the per protocol population (P = .0059).

Among patients with clarithromycin-resistant strains of H. pylori, in the modified intention-to-treat population, 31.9% achieved eradication with PPI triple therapy, compared with 65.8% in the vonoprazan triple-therapy group, and 69.6% in the vonoprazan dual-therapy group. In the per protocol population, the numbers were 29.0% versus 67.2% and 79.5%, respectively (P < .0001 for both versus PPI triple therapy).

Among all patients, in the modified intention-to-treat population, 68.5% achieved eradication with PPI triple therapy, 80.8% with vonoprazan triple therapy (P =. 0001), and 77.2% with vonoprazan dual therapy (P = .0063)*. In the per protocol population, the numbers were 70.0%, 85.7% (P < .0001), and 81.1% (P = .0013), respectively.

Safety outcomes were similar among the three groups, with treatment-emergent adverse events occurring in 34.5% of the PPI triple-therapy group (1.2% discontinued), 34.1% of the vonoprazan triple-therapy group (2.3% discontinued), and 29.9% in the vonoprazan dual-therapy group (0.9% discontinued).

Fighting against resistance

The efficacy of PPI-based clarithromycin-based triple therapy has fallen below 80% in the United States and Europe over the past few decades, largely because of antibiotic resistance, said William Chey, MD, during a presentation of the results at the annual meeting of the American College of Gastroenterology. Dr. Chey is a professor of medicine and director of the GI physiology laboratory at Michigan Medicine.

Vonoprazan is more stable in acid than are PPIs, and produces greater and more durable acid reduction, according to Dr. Chey. That’s important for two reasons: One is that some antibiotics are acid-labile, and so may have their efficacy directly impacted in a more acidic environment. The other factor is that most antibiotics work better on bacteria that are actively replicating, and H. pylori reproduces better in a more neutral environment. “So, you increase the replication, you increase the bioavailability of the antibiotics. And therefore, hopefully, that underlies why we see it working better in the patients with [antibiotic] resistance,” Dr. Chey said in an interview.

It remains to be seen whether or not the drug will receive FDA approval, but he pointed to other regimens like bismuth quadruple therapy and rifabutin-based triple therapy that are already available. “If I had the choice, I would never use a PPI-based triple therapy again. People should not be doing that,” said Dr. Chey.

“More successful H. pylori eradication regimens are certainly needed, and these results are particularly relevant and interesting given the increasing failure of initial treatment regimens,” said Kimberly Harer, MD, who moderated the session. She noted that the secondary analysis of patients with clarithromycin-resistant infections was particularly relevant. “The superiority analysis indicating vonoprazan triple therapy resulted in increased H. pylori eradication compared to lanzoprazole triple therapy was especially interesting,” said Dr. Harer, who is a clinical lecturer at University of Michigan Health, Ann Arbor.

One downside to the study is that it didn’t compare vonoprazan combinations to quadruple therapy of a PPI, bismuth, tetracycline, and a nitroimidazole, said Joseph Jennings, MD, who was asked to comment on the study. Other treatment approaches include sequential antibiotics and other combinations. Dr. Jennings also highlighted the findings that the vonoprazan regimens were superior against clarithromycin-resistant strains. “The more different regimens we can add to the armamentarium, the better chance we have because the resistant patterns fluctuate all throughout the world,” said Dr. Jennings, who is an assistant professor of medicine at Georgetown University and director of the center for GI bleeding at MedStar Georgetown University Hospital, both in Washington.

He also pointed out that physicians can face a conundrum when patients fail multiple lines of therapy and have testing done that shows high levels of resistance. Some have allergies that prevent them from turning to other antibiotics. “That’s a market where lots of doctors struggle. Something like this would be a nice add-on,” said Dr. Jennings.

One downside to the study is that it didn’t compare vonoprazan combinations to quadruple therapy of a PPI, bismuth, tetracycline, and a nitroimidazole, said Joseph Jennings, MD, who was asked to comment on the study. Other treatment approaches include sequential antibiotics and other combinations. Dr. Jennings also highlighted the findings that the vonoprazan regimens were superior against clarithromycin-resistant strains. “The more different regimens we can add to the armamentarium, the better chance we have because the resistant patterns fluctuate all throughout the world,” said Dr. Jennings, who is an assistant professor of medicine at Georgetown University and director of the center for GI bleeding at MedStar Georgetown University Hospital, both in Washington.

He also pointed out that physicians can face a conundrum when patients fail multiple lines of therapy and have testing done that shows high levels of resistance. Some have allergies that prevent them from turning to other antibiotics. “That’s a market where lots of doctors struggle. Something like this would be a nice add-on,” said Dr. Jennings.

LAS VEGAS – In the treatment of Helicobacter pylori infection, combination therapies using the oral potassium-competitive acid blocker vonoprazan were superior to standard proton pump inhibitor (PPI)–based triple therapy, producing higher eradication rates, according to combined data from a U.S. and a European phase 3 randomized, controlled trial.

Vonoprazan has been submitted to the Food and Drug Administration for approval with a Fast Track designation in combination with amoxicillin and clarithromycin (triple therapy) or amoxicillin alone (dual therapy) for treating H. pylori infection. It has already been approved in Japan for the treatment of gastric and duodenal ulcers, reflux esophagitis, secondary prevention of low-dose aspirin– or nonsteroidal anti-inflammatory drug–induced gastric mucosal damage, and for first and second-line H. pylori eradication therapy.

Study details

The study included 1,046 treatment-naive patients who had dyspepsia, a recent or new diagnosis of a nonbleeding peptic ulcer, a history of a peptic ulcer, or long-term stable use of an NSAID. Patients were randomized to PPI-based triple therapy (lansoprazole, amoxicillin, clarithromycin), vonoprazan triple therapy (plus amoxicillin, clarithromycin), or vonoprazan dual therapy (amoxicillin). The treatment period was 14 days, followed by 13C urea breath test (UBT) 4 weeks after treatment.

The researchers conducted several analyses, including: Modified intention-to-treat analyses, which included all enrollees; per protocol analyses, which included patients who took at least 75% of each study medication and underwent 13C UBT in the expected time frame; and a safety population of all patients who took at least one study drug.

Among patients with H. pylori strains that were not resistant to clarithromycin, the PPI-based triple-therapy group had an eradication rate of 78.8%, compared with 84.7% in the vonoprazan triple-therapy group (P < .0001), and 78.5% in the vonoprazan dual-therapy group (P = .0037). In the per protocol analysis, PPI-based triple therapy eradicated H. pylori 82.1% of the time, compared with 90.4% in the vonoprazan triple-therapy group (P < .0001) and 81.2% in the vonoprazan dual-therapy group (P = .0077). Both vonoprazan treatment groups were noninferior to PPI-based triple therapy.

A prespecified exploratory analysis found that vonoprazan triple therapy outperformed PPI-based triple therapy in the modified intention-to-treat population (P = .0408) and the per protocol population (P = .0059).

Among patients with clarithromycin-resistant strains of H. pylori, in the modified intention-to-treat population, 31.9% achieved eradication with PPI triple therapy, compared with 65.8% in the vonoprazan triple-therapy group, and 69.6% in the vonoprazan dual-therapy group. In the per protocol population, the numbers were 29.0% versus 67.2% and 79.5%, respectively (P < .0001 for both versus PPI triple therapy).

Among all patients, in the modified intention-to-treat population, 68.5% achieved eradication with PPI triple therapy, 80.8% with vonoprazan triple therapy (P =. 0001), and 77.2% with vonoprazan dual therapy (P = .0063)*. In the per protocol population, the numbers were 70.0%, 85.7% (P < .0001), and 81.1% (P = .0013), respectively.

Safety outcomes were similar among the three groups, with treatment-emergent adverse events occurring in 34.5% of the PPI triple-therapy group (1.2% discontinued), 34.1% of the vonoprazan triple-therapy group (2.3% discontinued), and 29.9% in the vonoprazan dual-therapy group (0.9% discontinued).

Fighting against resistance

The efficacy of PPI-based clarithromycin-based triple therapy has fallen below 80% in the United States and Europe over the past few decades, largely because of antibiotic resistance, said William Chey, MD, during a presentation of the results at the annual meeting of the American College of Gastroenterology. Dr. Chey is a professor of medicine and director of the GI physiology laboratory at Michigan Medicine.

Vonoprazan is more stable in acid than are PPIs, and produces greater and more durable acid reduction, according to Dr. Chey. That’s important for two reasons: One is that some antibiotics are acid-labile, and so may have their efficacy directly impacted in a more acidic environment. The other factor is that most antibiotics work better on bacteria that are actively replicating, and H. pylori reproduces better in a more neutral environment. “So, you increase the replication, you increase the bioavailability of the antibiotics. And therefore, hopefully, that underlies why we see it working better in the patients with [antibiotic] resistance,” Dr. Chey said in an interview.

It remains to be seen whether or not the drug will receive FDA approval, but he pointed to other regimens like bismuth quadruple therapy and rifabutin-based triple therapy that are already available. “If I had the choice, I would never use a PPI-based triple therapy again. People should not be doing that,” said Dr. Chey.

“More successful H. pylori eradication regimens are certainly needed, and these results are particularly relevant and interesting given the increasing failure of initial treatment regimens,” said Kimberly Harer, MD, who moderated the session. She noted that the secondary analysis of patients with clarithromycin-resistant infections was particularly relevant. “The superiority analysis indicating vonoprazan triple therapy resulted in increased H. pylori eradication compared to lanzoprazole triple therapy was especially interesting,” said Dr. Harer, who is a clinical lecturer at University of Michigan Health, Ann Arbor.

Fundraising walks for multiple sclerosis (MS) should be familiar to everyone nationwide. They serve to raise money for MS, bolster public awareness of the disease, and build a sense of community. But such in-person events took a big hit during the pandemic.

Recently, this news organization spoke with Kristin Gibbs, vice president of Walk MS for the National MS Society. She described the challenges posed by the COVID pandemic on the National MS Society’s efforts to fundraise on behalf of the MS community.
 

How has the National MS Society raised money before the pandemic?

We are a peer-to-peer fundraising event. That means our registered participants ask their family, friends and coworkers to support them by donating. More than 90% of our participants are friends-and-family teams, and nearly everyone who participates in Walk MS has a connection to MS. We do also have corporate and national teams that fundraise, as well as national and local sponsors that provide monetary support of Walk MS.



About how many Walk MS events were held nationally in an average prepandemic year?

Going back to 2019, we held almost 400 Walk MS events. Next year, the Society will host 234 events, with at least one in each state. The reduction in the number of events reflects a prepandemic strategy of focusing our limited resources in areas where we can have the biggest impact.



How has the pandemic impacted fundraising and community building/outreach?

Fewer people registered and participated in our virtual events in 2020 and 2021, and the pandemic made it challenging for participants to fundraise. While normally we might see more than 200,000 participants nationally, in 2021 we attracted 40,000. Our fundraising decreased from nearly $40 million in prepandemic years to around $20 million in 2021. Our experience is similar to that of most nonprofit peer-to-peer events. However, we were encouraged by the individuals who did support Walk MS during the pandemic, as their fundraising averages were higher than prepandemic campaigns.



What kinds of ‘virtual events’ were held during the pandemic lockdowns?

When it comes to building community, during the pandemic we innovatively utilized online gathering technology, especially Teams, to bring our Walk MS participants together. We held numerous meetings for Team Captains and conducted pre-event pep rallies online to help share information and generate excitement. We produced Facebook Live broadcasts and launched a cutting-edge online version of a Walk MS event called Walk MS On Demand. On Demand visitors could create a virtual bib, learn about the Society, watch inspirational videos, and secure information from national and local sponsors.

 

How is fundraising handled nationally and locally?

In 2022 we will have 234 Walk MS events spread across the country. We are anticipating 100,000 participants will register and our goal is to raise $24 million. Our fundraising will come from individuals, teams, and corporations who contribute at the local and national levels. We are hopeful the excitement surrounding safely being back in person will allow the Walk MS campaign to quickly regain its financial and community-building impact.



Has the pandemic impacted corporate contributions?

We were extremely lucky to maintain support of our national sponsors, and to engage a strong number of local partners. Because we offered the Walk MS On Demand online experience where sponsors could showcase their companies in innovative ways, even though we were virtual we could provide our important partners with a unique way to connect to our constituents. That made a tremendous difference. Also, our partners are strongly committed to the mission and knew their continued support during the pandemic was critical to our organization.



How is the money distributed? Who benefits and how? 

Walk MS is the United States’ 7^th-largest nonprofit walk series, and the 12^th-largest nonprofit event overall. Our Walk MS funds help provide support, programming, and research for individuals diagnosed with MS. Over the history of Walk MS, participants and sponsors have generated more than $1 billion to support those who live with MS.

LAS VEGAS – The G-EYE colonoscope facilitates detection of adenomas more so than does the Endocuff Vision, researchers say.

In the first head-to-head comparison of two mechanical enhancement colonoscopy devices, “the G-EYE demonstrated a meaningful increase in adenoma detection rate [ADR] over Endocuff, particularly for advanced adenomas,” said Seth Gross, MD, a professor of medicine at New York University.

Previous studies have shown that mechanical enhancements are more effective than optical enhancements, Dr. Gross said. “To take it a step further, when you look at mechanical devices, especially these two, in past studies, the G-EYE has been sort of the leader in adenoma detection,” he told this news organization.

But until now, no studies had compared them head to head, said Dr. Gross, who presented the finding here at the American College of Gastroenterology (ACG) 2021 Annual Scientific Meeting.

The two devices work differently. The Endocuff Vision fits onto the colonoscope tip. During withdrawal, it expands radially, and its arms flatten the folds within the colon. The G-EYE balloon is deflated at insertion, then is inflated at the cecum, smoothing the colon wall while centering the colonoscopic view.

To compare the two, Dr. Gross and colleagues randomly assigned 363 patients to undergo colonoscopy with G-EYE and 364 patients to undergo colonoscopy with Endocuff Vision. The two groups were similar in demographics.

Withdrawal times were >6 minutes in both groups. The researchers detected adenomas in a higher percentage of patients with the G-EYE than with the Endocuff Vision. The same was true for advanced adenomas.

When using the G-EYE, the researchers also found more adenomas per patient, more sessile serrated adenomas per patient, more large adenomas per patient, and more right colon adenomas per patient.

A “green” adaptation to the traditional Mediterranean diet could help improve insulin sensitivity and reduce visceral fat by increasing levels of ghrelin, the “hunger hormone,” new research suggests.

The current study is a new analysis of data from the randomized DIRECT-PLUS trial, which showed that the addition of green tea and substitution of red meat for a plant-based (Mankai) protein shake at dinner – dubbed the “green Mediterranean diet” – resulted in further improved cardiometabolic benefits compared with the traditional Mediterranean diet among people with baseline abdominal obesity and/or dyslipidemia, according to the researchers.

They specifically looked at ghrelin, nicknamed the “hunger hormone,” a neuropeptide mainly secreted by the gastric epithelium. It acts on the pituitary gland to release growth hormone. Ghrelin concentrations increase during fasting and decrease after eating. Lower levels are associated with insulin resistance and obesity.

Fasting ghrelin levels were elevated with weight loss, but those increases were associated with improved insulin sensitivity and regression of visceral adipose tissue even beyond weight loss.

Although the caloric restriction and weight loss were comparable with the two Mediterranean diets, the green Mediterranean diet group had double the increase in fasting ghrelin as the traditional Mediterranean diet group, the researchers point out in their report .
 

‘Hypothesis-generating’ study pushes many hot topic buttons

“This specific study is the first to show that ghrelin levels play an important role in metabolic adaptation to a dietary or lifestyle intervention and that ghrelin is an important player in the axis of adiposity, insulin resistance, and metabolic health,” lead researcher Gal Tsaban, MD, told this news organization.

The data partially explain some of the prior beneficial effects seen with the Green Mediterranean diet, even after adjustment for weight loss, he explained, noting that the revised version of the diet “could be considered as an alternative lifestyle intervention with possible metabolic benefits even beyond the Mediterranean diet, which is what we currently recommend for patients.”

Asked for comment, Christopher Gardner, PhD, was not as enthusiastic.

He took issue with the fact that ghrelin wasn’t a primary or even a prespecified secondary outcome of the DIRECT-PLUS trial and because the specific plant-based ingredients of the green Mediterranean diet used in the study may not be widely available or desirable and therefore limit the study’s generalizability.

Dr. Gardner, who is director of nutrition studies at the Stanford Prevention Research Center, California, also said: “They’re tying lots of interesting things together. The Mediterranean diet is a cool thing, ghrelin is a cool thing, and insulin resistance is hugely important in this day and age, even though we don’t all agree on how to measure it.”

“But it gets tough as you try to link them all together for an exploratory outcome. ... To me it’s an interesting hypothesis-generating study that pushes a lot of interesting buttons that are hot topics in the field.”
 

Green Mediterranean diet led to higher ghrelin, metabolic benefits

In DIRECT-PLUS, a total of 294 adults (88% men) older than 30 years of age with abdominal obesity (waist circumference >102 cm for men or >88 cm for women), or dyslipidemia (triglycerides >150 mg/dL and HDL-cholesterol ≤40 mg/dL for men or ≤50 mg/dL for women) were included. Half had prediabetes or type 2 diabetes.

They were randomized to one of three diets: a diet based on standard healthy dietary guidelines; a traditional Mediterranean diet low in simple carbohydrates, rich in vegetables, with poultry and fish replacing beef and lamb and 28 g/day of walnuts; or the Green-Mediterranean diet, including 3-4 cups/day of green tea and 100 g/day of a green shake made from the Mankai strain of Wolffia globosa (also known as duckweed) replacing dinner, and 28 g/day of walnuts.

The Green Mediterranean diet included 800 mg more polyphenols than the traditional Mediterranean diet. Both were equally calorie-restricted, at about 1,500-1,800 kcal/day for men and 1,200-1,400 kcal/day for women. All three groups were instructed to engage in regular physical activity and were given free gym memberships.

The retention rate was 98.3% after 6 months and 89.8% after 18 months.

Weight loss was similar between the two Mediterranean diet groups (2.9% and 3.9% for the traditional and green versions, respectively) compared with the standard healthy diet (0.6%) (P < .05 for both Mediterranean diet groups vs. control).

After 6 months, fasting ghrelin increased in the traditional (8.0%; P = .015) and green (10.5%; P = 0.031) Mediterranean groups versus baseline, with no significant change in the control group.

By 18 months, fasting ghrelin was significantly greater compared with baseline only in the green Mediterranean group (P = .012).

Because the differences in fasting ghrelin trajectories were only significant in men – likely due to the small sample size of women – a subsequent 18-month analysis was limited to the men. In a multivariate model adjusted for age, intervention group, baseline biomarker values, and 18-month weight changes, the 18-month change in fasting ghrelin remained a significant predictor for changes in A1c and homeostatic model of insulin resistance (HOMA-IR; P = .022).

Because weight loss remained the most significant predictor of improved insulin resistance, a further analysis examined the association between changes in fasting ghrelin levels with changes in the fraction of insulin resistance marker that were not attributed to weight loss, per se. With the other adjustments, fasting ghrelin was associated with residual reductions in A1c (P = .003), HOMA-IR (P = .021), increased HDL-cholesterol (P = .024), and relative visceral adipose tissue loss (P = .003).  
 

No specific product needed to push Mediterranean diet towards vegan

Dr. Tsaban, a nutritional researcher and cardiologist at Ben-Gurion University and Soroka University Medical Center, Be’er-Sheva, Israel, said the Mankai shake is commonly consumed in Israel but is also available worldwide. The study participants, all employees at an isolated nuclear research facility in the Negev, were particularly motivated. “They didn’t have a satiety problem with the drink. It made them very full,” he said. The manufacturer supplied the shakes but didn’t fund the study, he added.

However, Dr. Tsaban said that the “green Mediterranean diet” doesn’t depend on specific products.

Rather, “the concept is to push the Mediterranean diet a bit further and to replace the animal-based protein with vegetable-based protein, to shift your dietary habits towards a more vegan lifestyle. It’s not completely vegan, but it’s trending there. ... Our main goal was to increase the polyphenol intake, the antioxidant intake from vegetables. ... I think it can be replicated.”

Dr. Gardner said, “At the end of the day, it’s an exploratory study. ... It raises some interesting points that give the rest of us room to follow-up on.”

The study was funded by grants from the German Research Foundation, the Israel Ministry of Health, the Israel Ministry of Science and Technology, and the California Walnut Commission. Dr. Tsaban has reported no further relevant financial relationships. Dr. Gardner has reported receiving study funding from Beyond Meat.

They specifically looked at ghrelin, nicknamed the “hunger hormone,” a neuropeptide mainly secreted by the gastric epithelium. It acts on the pituitary gland to release growth hormone. Ghrelin concentrations increase during fasting and decrease after eating. Lower levels are associated with insulin resistance and obesity.

Fasting ghrelin levels were elevated with weight loss, but those increases were associated with improved insulin sensitivity and regression of visceral adipose tissue even beyond weight loss.

Although the caloric restriction and weight loss were comparable with the two Mediterranean diets, the green Mediterranean diet group had double the increase in fasting ghrelin as the traditional Mediterranean diet group, the researchers point out in their report .
 

‘Hypothesis-generating’ study pushes many hot topic buttons

“This specific study is the first to show that ghrelin levels play an important role in metabolic adaptation to a dietary or lifestyle intervention and that ghrelin is an important player in the axis of adiposity, insulin resistance, and metabolic health,” lead researcher Gal Tsaban, MD, told this news organization.

The data partially explain some of the prior beneficial effects seen with the Green Mediterranean diet, even after adjustment for weight loss, he explained, noting that the revised version of the diet “could be considered as an alternative lifestyle intervention with possible metabolic benefits even beyond the Mediterranean diet, which is what we currently recommend for patients.”

Asked for comment, Christopher Gardner, PhD, was not as enthusiastic.

He took issue with the fact that ghrelin wasn’t a primary or even a prespecified secondary outcome of the DIRECT-PLUS trial and because the specific plant-based ingredients of the green Mediterranean diet used in the study may not be widely available or desirable and therefore limit the study’s generalizability.

Dr. Gardner, who is director of nutrition studies at the Stanford Prevention Research Center, California, also said: “They’re tying lots of interesting things together. The Mediterranean diet is a cool thing, ghrelin is a cool thing, and insulin resistance is hugely important in this day and age, even though we don’t all agree on how to measure it.”

“But it gets tough as you try to link them all together for an exploratory outcome. ... To me it’s an interesting hypothesis-generating study that pushes a lot of interesting buttons that are hot topics in the field.”
 

Green Mediterranean diet led to higher ghrelin, metabolic benefits

In DIRECT-PLUS, a total of 294 adults (88% men) older than 30 years of age with abdominal obesity (waist circumference >102 cm for men or >88 cm for women), or dyslipidemia (triglycerides >150 mg/dL and HDL-cholesterol ≤40 mg/dL for men or ≤50 mg/dL for women) were included. Half had prediabetes or type 2 diabetes.

They were randomized to one of three diets: a diet based on standard healthy dietary guidelines; a traditional Mediterranean diet low in simple carbohydrates, rich in vegetables, with poultry and fish replacing beef and lamb and 28 g/day of walnuts; or the Green-Mediterranean diet, including 3-4 cups/day of green tea and 100 g/day of a green shake made from the Mankai strain of Wolffia globosa (also known as duckweed) replacing dinner, and 28 g/day of walnuts.

The Green Mediterranean diet included 800 mg more polyphenols than the traditional Mediterranean diet. Both were equally calorie-restricted, at about 1,500-1,800 kcal/day for men and 1,200-1,400 kcal/day for women. All three groups were instructed to engage in regular physical activity and were given free gym memberships.

The retention rate was 98.3% after 6 months and 89.8% after 18 months.

Weight loss was similar between the two Mediterranean diet groups (2.9% and 3.9% for the traditional and green versions, respectively) compared with the standard healthy diet (0.6%) (P < .05 for both Mediterranean diet groups vs. control).

After 6 months, fasting ghrelin increased in the traditional (8.0%; P = .015) and green (10.5%; P = 0.031) Mediterranean groups versus baseline, with no significant change in the control group.

By 18 months, fasting ghrelin was significantly greater compared with baseline only in the green Mediterranean group (P = .012).

Because the differences in fasting ghrelin trajectories were only significant in men – likely due to the small sample size of women – a subsequent 18-month analysis was limited to the men. In a multivariate model adjusted for age, intervention group, baseline biomarker values, and 18-month weight changes, the 18-month change in fasting ghrelin remained a significant predictor for changes in A1c and homeostatic model of insulin resistance (HOMA-IR; P = .022).

Because weight loss remained the most significant predictor of improved insulin resistance, a further analysis examined the association between changes in fasting ghrelin levels with changes in the fraction of insulin resistance marker that were not attributed to weight loss, per se. With the other adjustments, fasting ghrelin was associated with residual reductions in A1c (P = .003), HOMA-IR (P = .021), increased HDL-cholesterol (P = .024), and relative visceral adipose tissue loss (P = .003).  
 

No specific product needed to push Mediterranean diet towards vegan

Dr. Tsaban, a nutritional researcher and cardiologist at Ben-Gurion University and Soroka University Medical Center, Be’er-Sheva, Israel, said the Mankai shake is commonly consumed in Israel but is also available worldwide. The study participants, all employees at an isolated nuclear research facility in the Negev, were particularly motivated. “They didn’t have a satiety problem with the drink. It made them very full,” he said. The manufacturer supplied the shakes but didn’t fund the study, he added.

However, Dr. Tsaban said that the “green Mediterranean diet” doesn’t depend on specific products.

Rather, “the concept is to push the Mediterranean diet a bit further and to replace the animal-based protein with vegetable-based protein, to shift your dietary habits towards a more vegan lifestyle. It’s not completely vegan, but it’s trending there. ... Our main goal was to increase the polyphenol intake, the antioxidant intake from vegetables. ... I think it can be replicated.”

Dr. Gardner said, “At the end of the day, it’s an exploratory study. ... It raises some interesting points that give the rest of us room to follow-up on.”

The study was funded by grants from the German Research Foundation, the Israel Ministry of Health, the Israel Ministry of Science and Technology, and the California Walnut Commission. Dr. Tsaban has reported no further relevant financial relationships. Dr. Gardner has reported receiving study funding from Beyond Meat.

The CDC is urging parents and guardians to vaccinate children ages 5-11 against COVID-19 once the shot is fully approved, despite questions from FDA advisers about the urgency given falling national case rates.

On Oct. 26, the FDA’s Vaccines and Related Biological Products Advisory Committee voted to recommend a 10-microgram shot for children. Though 17 of the 18 panelists voted in favor of it, some members said it was a hard decision and questioned the need for it now that cases and hospitalizations are down.

“There’s urgency because we’re seeing disease in children, we’ve seen deaths in children, we’ve seen long COVID,” CDC Director Rochelle Walensky, MD, said at a White House briefing on Oct. 27. “Certainly we’ve seen cases come down before, and the way to prevent surges again is to get more and more people vaccinated.”

CDC data presented at an Oct. 26 advisory committee meeting show that among children 5-11, COVID-19 was one of top 10 causes of death over last year, Dr. Walensky said. There have been more than 8,300 hospitalizations and 745 deaths in children under 18.

As of yesterday, the 7-day average of daily COVID-19 cases was 65,900, a 16% decrease from the prior week. Hospitalizations are down 54% from the week of Aug. 28, Dr. Walensky said.

“If the trends continue the way they are going, the emergency for children is not what we might think it would be. That was my concern,” James Hildreth, MD, president and CEO at Meharry Medical College in Nashville, said at the advisory committee meeting on Oct. 26.

But according to one CDC study, hospitalization rates for adolescents were 10 times higher in those who were unvaccinated. Another study found that COVID-related emergency room visits and hospital admissions among children were more than 3 times as high in states with the lowest vaccination rates.

“We are down from our peak in early September, and we are now heading in the right direction, but with cases still high, we must remain vigilant heading into the colder, drier winter months,” Dr. Walensky said, noting that the 7-day average of daily deaths still exceeds 1,000.

Meanwhile, the booster program is off to a “very strong start,” said White House COVID-19 Response Coordinator Jeff Zients.

In the 5 days since authorizations, about 15 million people have received an additional dose of the Pfizer, Moderna, and Johnson & Johnson vaccines.

Researchers writing in the British Journal of Dermatology confirm the long-term use of hydrochlorothiazide is associated with a dose-dependent, twofold increased risk of squamous cell carcinoma, compared with calcium channel blocker use.

The findings were originally reported in two Danish case-control studies in which physicians reported a fourfold increased risk of squamous cell carcinoma, and a moderate increased risk of basal cell carcinoma and cutaneous malignant melanoma in patients who used hydrochlorothiazide long-term.

And, while the new study did not find an increased risk of basal cell carcinoma and cutaneous malignant melanoma among long-term users of hydrochlorothiazide, they suggest that bendroflumethiazide “may be a safer alternative for patients at increased risk of skin cancer.” The long-term use of indapamide was associated with a moderately increased risk of cutaneous malignant melanoma but did not alter the risk of either squamous cell or basal cell carcinoma

“Our results suggest that bendroflumethiazide may be a safer alternative to hydrochlorothiazide and indapamide, especially for patients at increased risk of skin cancer, but future studies are needed to rule out a causal association between bendroflumethiazide and cutaneous malignant melanoma,” wrote authors who were led by Christoph R. Meier, PhD, a professor in pharmacy with University Hospital Basel (Switzerland) and a contributor to the Boston Collaborative Drug Surveillance Program.

This study adds to existing evidence that there is a dose-dependent increased risk of squamous cell carcinoma in users of high cumulative doses of hydrochlorothiazide, compared with non–hydrochlorothiazide users.

The study, an observational cohort study, was published earlier this year. It is based on data from the U.K.-based Clinical Practice Research Datalink. It included 271,154 new users of thiazides and thiazidelike diuretics, the majority at 87.6% having been prescribed bendroflumethiazide, 5.8% indapamide, and 3.6% hydrochlorothiazide. Outcomes were compared to those observed in 275,263 users of calcium channel blockers.

“The three primary outcomes of interest were a first-time diagnosis of cutaneous malignant melanoma, basal cell carcinoma, or squamous cell carcinoma,” the authors wrote.

Incidence rates and incidence rate ratios were estimated for both short-term and long-term users of thiazidelike diuretics and calcium channel blockers, while a propensity score (PS) analysis was done in order to control for 23 baseline covariates. The mean follow-up after PS weighting was 3.9 years for indapamide users and 5.5 years for hydrochlorothiazide users. Overall, the incidence rate ratios of squamous cell carcinoma were not markedly increased for either short-term or long-term users of thiazidelike diuretics, the authors reported.

In contrast, the incidence rate ratios of squamous cell carcinoma for hydrochlorothiazide users were increased by 29% for short-term users at an IRR of 1.29 while they were increased by almost twofold for long-term hydrochlorothiazide users at an IRR of 1.95.

Long-term use of hydrochlorothiazide was again associated with a 64% increased risk of basal cell carcinoma, compared with users of a renin-angiotensin inhibitor at a weighted IRR of 1.64.

In contrast, weighted incident rate ratios for basal cell carcinoma for both short-term and long-term thiazide users were not significantly different and results were similar for patients who took hydrochlorothiazide, indapamide, or bendroflumethiazide.

Weighted overall incident rate ratios for cutaneous malignant melanoma were not significantly different for either short-term or long-term users of thiazidelike diuretics, compared with calcium channel blocker users.

However, there was a 43% increased risk of cutaneous malignant melanoma among long-term indapamide users at a weighted IRR of 1.43, compared with calcium channel blocker users, the authors reported.

“Given the biological plausibility and the severe clinical implications of cutaneous malignant melanoma, this finding should be considered carefully,” they cautioned.

Limitations to the study include the fact that the database analyzed does not have information on sun exposure, skin characteristics, or socioeconomic status which may affect the amount of sun exposure participants received.

The authors had no conflicts of interest to declare.

A human chorionic gonadotropin (hCG) test is commonly ordered by gynecologists prior to surgical procedures, in the workup of bleeding abnormalities, and in the follow-up of ectopic and molar pregnancies, to name a few indications. In doing so, occasionally clinicians will find themselves in the diagnostic dilemma of discovering an inexplicable low-level elevation in hCG, such as in a postmenopausal patient. This clinical picture can be confusing and can be concerning for conditions such as postmolar gestational trophoblastic neoplasia (GTN). However, there can be benign causes of this phenomenon.¹ To prevent unnecessary worry, investigation of treatments is important. In fact, misdiagnosis and inappropriate treatment of benign, low-level hCG levels with unnecessary chemotherapy is problematic mismanagement of gestational trophoblastic disease (GTD), and a major cause of litigation.

Human chorionic gonadotropin is a glycoprotein hormone with two subunits (alpha and beta). It can come from multiple sources, including trophoblastic cells, malignant trophoblastic cells, the pituitary gland, and exogenous sources.¹ Its alpha-subunit is identical to that of follicle stimulating hormone (FSH), luteinizing hormone (LH), and thyroid-stimulating hormone (TSH). Its beta-subunit is unique, though very similar to that of LH. The free hCG beta subunit can be produced by nontrophoblastic neoplasms. The gene for the beta subunit of hCG is in close proximity to the beta subunit of LH and increases in gonadotropin-releasing hormone (GnRH) in menopause can result in the stimulation of both genes. Understanding the sources of hCG-like glycoproteins and mechanisms for testing is important when considering possible causes for falsely elevated hCG.

Most commercially available serum hCG assays detect normal intact hCG and free beta subunits. They are typically sandwich assays utilizing antibody binding sites in which a solid-phase anti-hCG antibody to a specific hCG target is then mixed with the patient’s serum, trapping or binding the hCG, which is then treated with an indicator antibody. After being washed with the indicator or “capture” antibody, its relative (quantitative) levels can be measured.¹

Urine hCG testing (such as urine pregnancy tests) work through capillary action, drawing the patient’s urine across absorbent pads before reaching a pad which contains anti-hCG antibodies (the detection zone) in the test line. These tests are less sensitive than serum tests, but many can detect hCG levels <15-20 mIU/mL.¹

When ob.gyns. are asked to consult on or evaluate persistently low-level elevations of hCG in nonpregnant patients they should consider both malignant and nonmalignant etiologies. Malignant causes include GTN or quiescent GTD (e.g., after treatment of a molar pregnancy or GTN), choriocarcinoma (e.g., ovarian germ cell tumors), and nonchoriocarcinoma malignancies (such as cervical, pancreatic, breast, renal). Nonmalignant causes of hCG elevations in nonpregnant patients include pituitary hCG (in postmenopausal patients), exogenous hCG, and phantom hCG.

The first step in diagnostic workup is to perform a urine pregnancy test. Provided that the serum hCG level is > 20 mIU/mL, the urine HCG should be positive unless the cause of elevated levels is “phantom hCG” from heterophilic antibodies. When patients are exposed to animal antigens (such as in vaccines) they can develop antibodies such as human anti-mouse antibody. These antibodies have affinity to the binding antibodies used in many hCG sandwich assays and form a linkage between the solid phase antibody and the detection antibody creating a false-positive result. This false-positive test is only present in serum testing but not urine tests because the patient’s heterophilic antibodies are not excreted by the kidney and thus not available to create a false-positive result. An alternative method to make the diagnosis of phantom hCG is to request that the hCG testing be run at a different lab with a different assay (which may not react with the same affinity to the patient’s anti-animal heterophile antibodies), or to request that the lab perform serial dilutions. If phantom hCG from heterophile antibodies is at play, serial dilutions will result in a nonlinear dilution response.

If the patient’s urine hCG test is positive, then pregnancy should be ruled out with a transvaginal ultrasound. If negative, an ectopic pregnancy should still be considered (unless not medically plausible, such as in postmenopausal women or women who have undergone hysterectomy). In the absence of an intrauterine or ectopic pregnancy, a positive serum and urine pregnancy test could be from exogenous hCG, from malignancy or pituitary hCG. Use of exogenous hCG can be ruled out by taking a thorough history, with particular focus on asking about weight loss medications and muscle building therapies.

If pregnancy and exogenous hCG are ruled out, clinicians should assess for an occult hCG-secreting malignancy. The lab should be asked to measure the proportion of the free beta subunit of hCG, as this is typically what is secreted by malignancies. CT imaging of the chest, abdomen, and pelvis to search for an occult primary tumor should take place. If the patient has been recently treated for molar pregnancy or GTN, and serum hCG levels reside between 100 and 300 mIU/mL, quiescent GTD should be considered the diagnosis. Determination of the proportion of hyperglycosylated hCG to total hCG can help differentiate active choriocarcinoma from quiescent GTD. After restaging imaging has been done to confirm no measurable metastatic foci, observation can follow with monthly hCG measurements. The majority of these cases will eventually resolve without intervention within a year. Quiescent GTD and persistent low-level HCG in the absence of measurable GTN on imaging or symptoms does not require treatment with chemotherapy or hysterectomy, particularly in women who desire future fertility.²

Once occult malignancy has been ruled out, the remaining potential source of hCG is the pituitary gland. As mentioned earlier, hCG shares its morphology with TSH, LH, and FSH. This can result in cross reactivity and false positives. In the menopausal state, GnRH levels increase and thus so do pituitary LH and hCG levels. To confirm that the pituitary is the source of the low-level hCG levels, the provider should prescribe a course of hormonal treatment such as an oral contraceptive pill for a 2- to 3-month period. This should result in suppression of pituitary hCG, and serum hCG levels, as part of a negative feedback loop. Pituitary source of hCG is a benign condition, and, like quiescent GTD, phantom hCG or exogenous hCG does not require intervention.

Getting to the bottom of persistent low-level hCG elevations can be challenging. By following the step-wise algorithm listed here, clinicians can sequentially test for urine hCG, heterophilic antibodies, elevated free beta-subunit, occult malignancy, and pituitary hCG.

In patients with advanced cancer who are prescribed immune checkpoint inhibitors, comedications must be carefully assessed before patients start ICI therapy, most notably proton pump inhibitors, glucocorticoids, antibiotics, and psychotropic drugs.

“Our results confirm the detrimental impact on oncological outcomes of antibiotics and glucocorticoids at a dosage ≥10 mg/day when given within 1 month before or after ICI onset,” Marie Kostine, MD, of Bordeaux (France) University Hospital, and colleagues wrote in the European Journal of Cancer. “Moreover, we show that other comedications may significantly alter the antitumoral response of ICI, such as proton pump inhibitors, psychotropic drugs, morphine, aspirin, and insulin, whereas others seem to have no impact.”

While immune checkpoint inhibitors are transforming the treatment of advanced cancers, gut microbiota composition is an important determinant of response to ICIs. Antibiotic treatments are known to alter the gut microbiota. Other drugs, such as proton pump inhibitors, antidiabetic agents, aspirin, NSAIDs, glucocorticoids, immunomodulators, psychotropic drugs, and analgesics, have been associated with changes in microbiome composition. Since many patients with advanced cancer are exposed to such drugs, this study looked at the possible influence of these comedications on the antitumor effect and safety of ICIs.

The observational study included 635 patients with advanced cancer treated with ICIs between May 2015 and September 2017. Comedications given within 1 month before or 1 month after the first administration of an ICI were reviewed from medical records. Psychotropic drugs, proton pump inhibitors, ACE inhibitors and/or angiotensin II receptor blockers (ARBs), glucocorticoids, antibiotics, statins, and morphine were the most prescribed comedications.

Baseline use of antibiotics, glucocorticoids greater than 10 mg/day, proton pump inhibitors, psychotropic drugs, morphine, and insulin was associated with decreased overall survival and tumor response. However, the coadministration of statins, ACE inhibitors and/or ARBs, NSAIDs, aspirin, and oral diabetes drugs did not impact patient outcomes. Additionally, treatments that altered the response to ICIs were associated with a decreased incidence of immune-related adverse events.

“These results suggest some practical advice in a patient candidate to ICIs,” the authors wrote. “First, antibiotic treatment should be limited to documented infections,” and “withdrawal of proton pump inhibitors and psychotropic drugs should be considered.

“Regarding baseline glucocorticoids use, the cutoff of 10 mg/day should be respected, considering the deleterious effect of higher dosage. Moreover, because of the lack of impact of inhaled or topical glucocorticoids, local routes should be preferred,” the authors wrote. “Conversely, our study brings reassuring data regarding the use of glucocorticoids for the management of immune-related adverse events, which did not alter ICI efficacy, confirming previous reports.”

The authors noted that the observational nature of the study does not allow any causal conclusion, adding that it remains unknown whether the effect of comedications “on cancer outcomes is thoroughly mediated by changes in microbiota or other immunomodulatory properties.”

Along with the retrospective design, study limitations included reporting bias and missing data on baseline comedications, specific prognostic factors and cancer outcomes.

The authors noted no conflicts of interest.

New evidence points to the importance of helping mothers with their mental health during pregnancy.

Researchers from the National Institutes of Health in Bethesda, Md., have found that feelings of stress or depression while pregnant are linked to changes in the placenta where the child is growing. The findings, published in Epigenomics, show these changes could alter gene activity.

Stress and depression are not uncommon among expectant women, with depression affecting an estimated 1 in 10 pregnancies, according to the American College of Obstetricians and Gynecologists.

And current evidence already suggests that depression during pregnancy can negatively affect a child later in life. For instance, one study found that depression during pregnancy was linked to behavioral and emotional disorders during childhood, and another found that it raised the risk of depression at age 18.

To investigate stress and depression during pregnancy, the NIH investigators evaluated 301 pregnant women from 12 clinics in the United States who had taken part in an earlier clinical study. The group was ethnically diverse, with 34% identifying as Hispanic, 26% as non-Hispanic White, 24% as non-Hispanic Black, and 17% as Asian or Pacific Islander.

At the start of the study, the women were asked to complete questionnaires routinely used to screen for stress and depression. They completed the questionnaire five more times during their pregnancies. Shortly after each woman gave birth, researchers took tissue samples from the placenta and analyzed the genetics.

The purpose of studying the placenta, according to lead researcher Markos Tesfaye, MD, a postdoctoral fellow at the NIH, is that chemical changes can regulate whether a nearby gene can be activated.

There is evidence that chemical modifications in the placenta can lead to changes in fetal tissues, such as the brain, he said. And the placenta is known for making neurotransmitters, which are needed for fetal brain development.

The team found 16 areas where changes to the exterior of placental DNA were linked to depression in the second or third trimester. They also found two areas where these changes were associated with stress in the third trimester.

“Maternal depression leaves signals in the placenta at genes critical for fetal brain programming,” said study author Fasil Tekola-Ayele, PhD, from the NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Two of the chemical changes linked to depression were near genes that are known to be involved with fetal brain development and neurologic and psychiatric illnesses.

“The findings illustrate that the developing fetus is sensitive to the mother›s condition during pregnancy, including maternal symptoms of low mood and perceived stress,” said Thalia K. Robakis, MD, from the women’s mental health program at Icahn School of Medicine at Mount Sinai, New York, who was not involved in the study.

But Dr. Robakis cautioned that no clinical outcomes were measured among the babies born, meaning that the study could not document any effects of maternal depression and stress on fetal development. Rather, the work contributes to figuring out what mechanisms are involved.

“Pregnant women should continue to focus on optimizing their own physical and mental health,” Dr. Robakis said. “And they should know that a happy, healthy mother is the most important factor supporting the development of a happy, healthy baby.”

At the start of the study, the women were asked to complete questionnaires routinely used to screen for stress and depression. They completed the questionnaire five more times during their pregnancies. Shortly after each woman gave birth, researchers took tissue samples from the placenta and analyzed the genetics.

The purpose of studying the placenta, according to lead researcher Markos Tesfaye, MD, a postdoctoral fellow at the NIH, is that chemical changes can regulate whether a nearby gene can be activated.

There is evidence that chemical modifications in the placenta can lead to changes in fetal tissues, such as the brain, he said. And the placenta is known for making neurotransmitters, which are needed for fetal brain development.

The team found 16 areas where changes to the exterior of placental DNA were linked to depression in the second or third trimester. They also found two areas where these changes were associated with stress in the third trimester.

“Maternal depression leaves signals in the placenta at genes critical for fetal brain programming,” said study author Fasil Tekola-Ayele, PhD, from the NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Two of the chemical changes linked to depression were near genes that are known to be involved with fetal brain development and neurologic and psychiatric illnesses.

“The findings illustrate that the developing fetus is sensitive to the mother›s condition during pregnancy, including maternal symptoms of low mood and perceived stress,” said Thalia K. Robakis, MD, from the women’s mental health program at Icahn School of Medicine at Mount Sinai, New York, who was not involved in the study.

But Dr. Robakis cautioned that no clinical outcomes were measured among the babies born, meaning that the study could not document any effects of maternal depression and stress on fetal development. Rather, the work contributes to figuring out what mechanisms are involved.

“Pregnant women should continue to focus on optimizing their own physical and mental health,” Dr. Robakis said. “And they should know that a happy, healthy mother is the most important factor supporting the development of a happy, healthy baby.”

New evidence points to the importance of helping mothers with their mental health during pregnancy.

Researchers from the National Institutes of Health in Bethesda, Md., have found that feelings of stress or depression while pregnant are linked to changes in the placenta where the child is growing. The findings, published in Epigenomics, show these changes could alter gene activity.

Stress and depression are not uncommon among expectant women, with depression affecting an estimated 1 in 10 pregnancies, according to the American College of Obstetricians and Gynecologists.

And current evidence already suggests that depression during pregnancy can negatively affect a child later in life. For instance, one study found that depression during pregnancy was linked to behavioral and emotional disorders during childhood, and another found that it raised the risk of depression at age 18.
