The majority of participants were Hispanic with the average age of 43 years.\nScientists led by Ehimen Aneni, MD, MPH, used data from a 2014 voluntary Health Risk Assessment. Overall, employees with six or more hours of sleep had better diet, physical activity, body mass index and blood pressure when compared to those who slept less than six hours. These individuals were 2-3 times more likely to achieve optimal cardiovascular health. Better sleep was also associated with lower total health expenditures, less emergency room visits, and hospitalizations compared with those who slept less than six hours.\nThe study was funded by grant KL2 TR001862 from the National Center for Advancing Translational Science at the National Institutes of Health.\nEhimen C.

While this is a rare complication, the affected patients present acutely and at times, the condition is life-threatening.\nIn this report, researchers from across Yale School of Medicine, Columbia University Irving Medical Center, Virginia Commonwealth University School of Medicine, University of California, San Francisco, University of Utah Health Sciences Center and University of Utah School of Medicine found evidence of pancreatic inflammation, including reduction in pancreatic volume, in patients who received CPIs. They performed pre-clinical studies utilizing a mouse model and characterized changes in immune cells and pancreatic β cells leading to checkpoint inhibitor-induced diabetes. They showed that blocking inflammatory mediators in the mouse model resulted in prevention of diabetes caused by CPIs. \nTo learn more about their methods and analysis, read “Immune cells and their inflammatory mediators modify β cells and cause checkpoint inhibitor-induced diabetes” in JCI Insight. \nPerdigoto AL, Deng S, Du KC, Kuchroo M, Burkhardt DB, Tong A, Israel G, Robert ME, Weisberg SP, Kirkiles-Smith N, Stamatouli AM, Kluger HM, Quandt Z, Young A, Yang ML, Mamula MJ, Pober JS, Anderson MS, Krishnaswamy S, Herold KC.

PMID: 35925682.Clinical Tools for Identifying and Treating Unhealthy Alcohol Use \nUnhealthy alcohol use refers to the consumption of alcohol at a level that has caused or may cause adverse physical, psychological, or social consequences. In a recent article published in the Annals of Internal Medicine, Yale physicians review the latest evidence for the best methods of prevention, screening, diagnosis, and treatment of unhealthy alcohol use. \nAlthough associated with clear harms, alcohol consumption is common among adults in the U.S. Healthcare professionals should aim to inform adults—and the public—on the potential harms of alcohol consumption. Special attention should be directed toward alcohol use in populations who may have greatest risk of harm, such as young adults, older adults, women, persons with marginalized identities, and individuals with certain medical conditions or taking certain medications (e.g. prescription opioids). \nIn addition, patients often go without the proper screening and subsequent care for unhealthy alcohol use. It is recommended that standardized approaches with validated instruments are incorporated into practice settings and that screening in all patients for unhealthy alcohol use is made routine.\nPatients who have a negative screening result should be guided towards lower-risk alcohol use or abstinence. Those with a positive screening for unhealthy alcohol use require further assessment to determine their level of risk, from at-risk alcohol use to alcohol use disorders, in order to guide the next treatment steps. It is important to utilize the range of different treatment options, including brief interventions, psychosocial modalities, and medications.\nTo read the full article, go to Annals of Internal Medicine.\nDonroe JH, Edelman EJ.

During the pandemic, demand for inpatient palliative care surged at the same time the pandemic ushered in a new era of telehealth. In the face of mounting restrictions on in-person encounters, the result was a rapid and widespread rise in the use of telehealth-delivered palliative care (TPC) services in the inpatient setting.\nA team of Yale researchers sought to characterize the quality of TPC during the first 4-month peak of the pandemic, comparing it to care delivered during two other time periods: in-person palliative care two months prior to COVID-19 and during a post-peak, 2-month period when the majority of inpatient palliative care returned to in-person delivery.\nThe researchers found that palliative care consultations during peak COVID-19 occurred more frequently for discussions of goals of care or for referrals to hospice when compared to pre-COVID-19 consultations. Across all three time periods, the researchers found no differences in key quality metrics including the assessment of patients’ social needs, family burden, or goals of care. Despite major challenges in the early COVID-19 era, TPC served as a way to provide high-quality inpatient palliative care during this time.\nLearn more in “Quality of Telehealth-Delivered Inpatient Palliative Care During the Early COVID-19 Pandemic.”\nAnn A.

PTCL is categorized by their molecular features. Due to the diversity of PTCL, there is limited data available for treatments and disease course. \nClinicians at Yale School of Medicine and University of Miami School of Medicine performed a retrospective study using Epic records of flow cytometry lab results from Yale New Haven Hospital. Of the patient population looked at, 102 patients had flow cytometry available at diagnosis. They found that 27% of patients had peripheral blood involvement by flow cytometry, which correlated to bone marrow involvement. \nTo learn more about patient demographic information such as race, age, disease diagnosis, stage, first line treatment, and more, read “Peripheral Blood Involvement at Staging in Patients With Aggressive Peripheral T-Cell Lymphoma.”Avery J, Chandhok N, Rainey C, Torres R, Huntington S, Isufi I, Seropian S, Xu ML, Foss F.

A recent article published in The Lancet Psychiatry traces how experts are collaborating to provide OAT during war.\nExperts have adapted the Network for the Improvement of Addiction Treatment (NIATx) model for the Ukrainian context since 2014. With regional addiction treatment experts in Ukraine, the NIATx model has been used to overcome barriers to OAT scale-up and solve real-time problems with policy changes, the COVID-19 pandemic, and now during war. \nUkraine’s Public Health Center has been responsible for ensuring adequate supply of OAT. Meanwhile, OAT scale-up has been guided by non-governmental organizations like the Alliance for Public Health in collaboration with Yale University, using NIATx weekly coaching to respond to sudden changes during the war. Experts have successfully addressed medication shortages, heightened security concerns in conflict regions, and barriers to enrolling new patients whose risk increased due to the stressors of war. \nDespite an initial reduction in OAT patients, Ukraine rallied through NIATx to create collaborations between governmental and non-governmental OAT clinics, provide same-day access to treatment, and expand take-home dosing. Innovative practices emerged to respond to conflict and internally displaced persons, paving the way for sites throughout the country to adopt these effective strategies.

Researchers from three academic institutions including Yale School of Medicine conducted a study that reviewed postings from the American Cancer Society Cancer Survivors Network, an online, publicly available forum. The posts from adolescent and young adult cancer survivors, their family and friends in the "Young Cancer Survivors" discussion board from January 2010 to October 2020 were systematically assessed using a previously published cancer survivorship care framework. The researchers found that psychosocial issues were a top concern for adolescent and young adult cancer survivors, their family and friends.

PMID: 34471949.Is Taking Blood Pressure Medication at Bedtime More Effective Than Morning Dosing?\nAntihypertensive drug therapy is one of the most efficient medical interventions for preventing disability and death globally. Most of the evidence supporting its benefits has been derived from outcome trials with morning dosing of medications. Accumulating evidence suggests an adverse prognosis associated with night-time hypertension, non-dipping blood pressure (BP) profile and morning BP surge, with increased incidence of cardiovascular events during the first few morning hours. “These observations provide justification for complete 24-hour BP control as being the primary goal of antihypertensive treatment,” authors of a consensus document report in the Journal of Hypertension. A position paper by the International Society of Hypertension reviewed the published evidence to provide consensus recommendations for clinical practice.

Their sources included PubMed and Google Scholar. Their review revealed that an overall prevalence of food allergy appears to be increasing, and disproportionately affecting minority groups. “Racial and socioeconomic disparities are evident across all aspects of food allergy care: diagnosis, prevention, acute management,” such as access to epinephrine autoinjectors, visits to emergency department, and long-term management through oral immunotherapy,” the authors wrote. https://pubmed.ncbi.nlm.nih.gov/35476967/Tepler E, Wong KH, Soffer GK.
