Perinatal Mood Episodes in Men With Bipolar Disorder
In the first study of perinatal mood episodes (PMEs) among fathers with bipolar disorder, 36.2% reported experiencing episodes, with the onset being most common during their partner's pregnancy. This pattern contrasted with mothers who showed higher overall rates of PMEs (73%) and a peak onset within a week after delivery.
METHODOLOGY:
This study included 196 men and 597 women aged 18 years or older, who were biological fathers and mothers, respectively.
Participants had bipolar disorder diagnosed on the basis of the Diagnostic and Statistical Manual of Mental Disorders, Fourth or Fifth Edition, with a mood symptom onset before the age of 65 years.
They completed questionnaires about the occurrence of mood episodes during their partner's pregnancy or within 6 months postpartum.
TAKEAWAY:
Among fathers with bipolar disorder, 36.2% reported experiencing PMEs, with similar rates of depression and high/mixed mood/psychosis (17% and 18.6%, respectively).
Among mothers with bipolar disorder, 73% reported experiencing PMEs, with high/mixed mood/psychosis occurring more frequently than depression (44.5% vs 28.1%).
PME onset patterns differed between fathers and mothers, with fathers most commonly experiencing episodes during their partner's pregnancy vs mothers experiencing a peak onset within 1-week postpartum (41.9% vs 41.3%).
IN PRACTICE:
"Fathers do not undergo the same biological changes as mothers during the perinatal period which may partly explain the different patterns observed in the type and timings of PMEs between fathers and mothers with BD [bipolar disorder]," the authors wrote. These insights "may be useful for early identification and future prevention of paternal BD episodes, and may inform perinatal healthcare provision for fathers with BD," they added.
SOURCE:
This study was led by Ruth Brooks, Warwick Medical School, University of Warwick, Coventry, and Jemima Marsden, Three Counties Medical School, University of Worcester, Worcester, both in England. It was published online on July 9 in the Journal of Affective Disorders.
LIMITATIONS:
Rates of paternal PMEs were likely higher due to the retrospective nature of the study and the reliance on self-reporting. Other limitations were a potential selection bias and the study's focus on participants of European ancestry, limiting the generalisability of the findings to other populations.
DISCLOSURES:
This study was supported by grants from the Wellcome Trust and the Stanley Medical Research Institute. The authors reported having no conflicts of interest.

Trump's anti-DEI order sparks new federal funding guidance in Washington County
PORTLAND, Ore. () — Washington County has approved guidelines aimed at helping officials maintain critical funding amid President Donald Trump's anti-diversity, equity and inclusion policies. One of several established that entities with DEI practices would no longer be eligible for funding from the U.S. government. After several months of talks centered on how to preserve federal grants and other financial support, the Washington County Board of Commissioners voted to approve guiding principles during a meeting on Tuesday. CDC delves into bubonic plague case detected in Oregon in early 2024 The new guidance states that leaders will continue to operate 'in a transparent and open manner' while complying with federal, state and local regulations, among . Earlier in June, the its February 2020 commitment to DEI practices in response to the executive order. following pushback from several residents who argued leaders of the diverse county shouldn't adhere to the Trump administration's demands. However, County Administrator Tanya Ange noted that officials rely on $135 million in federal funding annually — and July through August is typically the period in which grants and contracts are renewed. Senior Medicare services administered through the Oregon Department of Human Services and overdose prevention programs managed by the Oregon Health Authority are among the resources that are currently 'at risk' as local officials wait to learn whether funding has been secured, according to Ange's . Despite uncertainty surrounding which resources will remain accessible in the county, some community members are arguing the new guidelines are too vague to ensure the protection of all residents. 'Simply changing the wording may not be enough to get the federal funds that we need, or maybe the wording is enough, but the resolution you pass is ambiguous enough to open the door for these funds to be made available for purposes they were not intended for — for not serving the under-resourced members of our community,' one testifier said. Ritz-Carlton in Portland sold back to lender to 'strengthen' struggling property District 1 Commissioner Nafisa Fai proposed an amendment that would have changed the guidelines to include language about Oregon's sanctuary state status, and to affirm that all Washington County residents would still have the right to access resources despite discrimination. When no other leaders voted to second the proposal, a decision that was met with 'boos' from attendees of the public hearing, District 4 Commissioner Jason Willey said legal counsel had already advised the county against changing the resolution.

PCPs Guide to Prescribing Blood Thinners for AF
As a primary care physician (PCP), you're often the first healthcare professional that will identify cardiac issues, including atrial fibrillation (AF). Individuals with AF face a fivefold risk for stroke. Therefore, these patients are often prescribed blood-thinning medications (anticoagulants) to slow blood clotting, according to the American Society of Hematology (ASH). Up to six million Americans have AF, the risk for which increases with age. The ASH says there are 450,000 hospitalizations each year because of AF. It's very important to check on your patient's response within the first few months of taking blood thinners. In fact, patients with AF who took low doses of oral anticoagulants experienced a higher incidence of bleeding episodes during the first 3 months of treatment, according to a study published in Blood Advances . When Should PCPs Prescribe Anticoagulants? PCPs should consider prescribing oral anticoagulants when they are the principal caregivers for patients with AF, acute deep venous thrombosis, or acute pulmonary embolism, according to R. Michael Benitez, MD, a cardiologist at the University of Maryland Medical Center and a professor of medicine in the Division of Cardiovascular Medicine at the University of Maryland School of Medicine in Baltimore. The decision to prescribe an oral anticoagulant must be based upon the patient's risk without anticoagulation weighed in context with the patient's risk for significant bleeding, he said. How Can Physicians Best Communicate the Rationale for Anticoagulant Therapy? When describing AF, PCPs can explain to patients that the upper chamber of heart is 'wiggling' and not effectively contracting and when blood is not being effectively moved forward, it tends to clot, said Benitez. Physicians can also share that a clot as small as 2 mm is large enough to cause a major stroke if it were to break loose from the inside of the top chamber and be pumped with the blood to the brain, suggested the cardiologist. 'The oral anticoagulant greatly reduces the risk of the formation of these blood clots and subsequent stroke,' Benitez said. 'Stroke is a terrible event that, if survived, often changes a patient's life permanently and significantly. In the setting of atrial fibrillation, anticoagulation greatly reduces the patient's risk of stroke.' Regarding deep venous thrombosis, physicians can explain that a blood clot in the leg veins could break loose and be pumped through the right side of the heart to the lungs. 'This event, pulmonary embolism, can cause critical illness or even death; the risk can be greatly reduced through the use of oral anticoagulants,' said Benitez. What Are Important Directives Regarding Usage? PCPs should stress that daily use is critical to the success of the drug in preventing stroke. 'In the case of the new direct oral anticoagulants, such as apixaban or rivaroxaban, the drugs both work very quickly but also wear off very quickly,' said Benitez. 'This means that even missing just 2-3 days is enough for the blood to again clot normally. It is essential that the drugs be taken daily to prevent stroke.' In the case of warfarin, the effect of the drug is more prolonged. While missing a single dose is unlikely to markedly change the degree of anticoagulation, it's still best to remind patients not to miss doses and take this daily as prescribed, according to Benitez. What Side Effects Should Be Discussed? It is extremely important with warfarin — and to a lesser degree with direct oral anticoagulants — to always make certain that there is no drug-drug interaction that might affect the degree of anticoagulation when new medications are introduced, such as antibiotics, said Benitez. Other side effects to bring to a patients' attention are minor bleeding (such as gum bleeding with dental flossing) or nose bleeds that stop easily, which don't require immediate medical attention. However, your patients should self-monitor bleeding episodes and know a course of action if injured. 'If bleeding will not readily stop then medical attention is needed, and patients who incur major injury or trauma are likely to be taken to an emergency facility where it is important for the staff caring for them to know what anticoagulant they are taking, the dose, and when they last took it,' Benitez said. 'Reversal agents are now available to normalize blood clotting.' Your patients may be concerned with food that could interact with these medications. Benitez said there are no significant food interactions or dietary restrictions. But when prescribing warfarin, some nutritional guidance is warranted. 'With warfarin, which is a vitamin K antagonist, it is essential that the patient limit their intake of food containing vitamin K, as it is essentially an antidote or reversal agent for the anticoagulant,' he said. Some sources of vitamin K are well-known, such as leafy vegetables like spinach, kale, and other greens. However, there are many other dietary sources rich in vitamin K that may not be as obvious, such as cauliflower and soy products, Benitez said. 'It is important for the patient to familiarize themselves with vitamin K-containing foods and to keep the intake of them low and steady from day to day if they are taking warfarin,' he said.

Gut-Brain Disorders Surge After Pandemic
There's been a striking rise in disorders of gut-brain interaction (DGBI), including irritable bowel syndrome (IBS) and functional dyspepsia, since the COVID-19 pandemic, new survey data from the UK and the US showed. 'Healthcare providers should recognize post-COVID DGBI as part of the long COVID spectrum. These post-COVID gut problems appear more severe and require more medical care than similar pre-pandemic conditions,' Imran Aziz, MBChB, MD, honorary consultant gastroenterologist and senior clinical lecturer, Sheffield Teaching Hospitals NHS Foundation Trust and University of Sheffield, Sheffield, England, told Medscape Medical News . Aziz and colleagues surveyed a nationally representative sample of 4050 adults in the UK and the US in 2017 (pre-pandemic) and repeated the survey in 4002 adults in 2023 (post-pandemic). The surveys included the Rome IV diagnostic questionnaire for DGBI and questions about nongastrointestinal somatic symptoms, anxiety and depression, quality of life, and healthcare use. The 2023 survey also asked about COVID-19 infection and illness history. The overall prevalence of DGBI (ie, meeting diagnostic criteria for at least one DGBI) increased significantly from the pre- to post-pandemic era (38% vs 47%; odds ratio [OR], 1.20), with similar findings independently noted in both countries. From pre- to post-pandemic, the rise in DGBI was observed within the esophageal (9% vs 10%; OR, 1.16), gastroduodenal (12% vs 16%; OR, 1.45), and bowel domains (30% vs 33%; OR, 1.12). Functional dyspepsia rose nearly 44% — from 8% to 12% (OR, 1.48) — and IBS increased 28% — from 5% to 6% (OR, 1.31). The rise in DGBI has been seen in both men and women and across all adult age groups. Multiple Factors at Play Aziz told Medscape Medical News the uptick is probably due to not only the direct impact of SARS-CoV-2 infection on the gastrointestinal tract but also to the psychological stress associated with pandemic life. 'In this study, we found that COVID-viral related factors contributing to DGBI include number of infections, abdominal pain and/or diarrhea during COVID-19 infection, and long COVID,' he explained. 'We also observed increased mood disturbances among people with DGBI in the post-pandemic era, but this study did not determine the direction of causality. Previous studies have shown that in one third of DGBI cases the mood disturbance precedes gut symptoms, while in two third of cases gut symptoms precede mood disturbances,' Aziz noted. The study was published online on July 30 in Clinical Gastroenterology and Hepatology . The results are in line with a recent study that found the prevalence of IBS and chronic idiopathic constipation among US adults rose significantly during the COVID-19 pandemic, with a near doubling of the national rate of IBS over 2 years, as reported previously by Medscape Medical News . Given a lack of high-quality clinical trials specifically for post-COVID DGBI management, 'healthcare providers should follow existing standard guidelines for functional dyspepsia and IBS,' Aziz advised. 'The established treatment protocols remain our best approach until more targeted research becomes available. It's also important to take a holistic approach. This means addressing not just the gut symptoms but also any accompanying mood disturbances. Many long-COVID clinics already provide this multiintegrated care model, which appears to be the most effective approach,' Aziz said.
