Future long duration space missions will expose astronauts to higher doses of galactic cosmic radiation (GCR) than those experienced on the international space station. Recent studies have demonstrated astronauts may be at risk for cardiovascular complications due to increased radiation exposure and fluid shift from microgravity. However, there is a lack of direct evidence on how the cardiovascular system is affected by GCR and microgravity since no astronauts have been exposed to exploratory mission relevant GCR doses.

Introduction: Buprenorphine is a highly effective medication for opioid use disorder (MOUD; OUD), which can be prescribed alongside naloxone in the primary care setting as part of a harm reduction approach to OUD. Despite this potential, implementation challenges have limited adoption of MOUD. To address barriers at the organizational level, we need better tools to measure perceived organizational support for the treatment of OUD and use of MOUD in the primary care setting.

Introduction: Buprenorphine and other medications for opioid use disorder (MOUD) are highly effective but substantially under prescribed in the rural United States. Among the most cited barriers to buprenorphine prescribing is stigma, yet little progress has been made in developing successful strategies to reduce stigma and increase access to life-saving medication. One of the key challenges to developing successful implementation strategies is understanding the different types of stigma that limit implementation.

There is a much debate regarding optimal selection in patients with metastatic cancer who should undergo local treatment (surgery or radiation treatment) to the primary tumor and/or metastases. Additionally, the optimal treatment of newly diagnosed metastatic cancer is largely unclear. Current prognostication systems to best inform these clinical scenarios are limited, as all metastatic patients are grouped together as having Stage IV disease without further incorporation of patient and disease-specific covariates that significantly impact patient outcomes.

Female agency and probable depression in the perinatal period and beyond: Longitudinal findings from rural Pakistan.

Soc Sci Med

January 2025

Department of Epidemiology, Gillings School of Global Public Health, University of North Carolina, 135 Dauer Drive, Chapel Hill, NC, 27599, USA; Carolina Population Center, University of North Carolina, 123 W Franklin Street, Chapel Hill, NC, 27516, USA.

In Pakistan, a setting with high gender inequality, the relationship between female agency and mental health has not been studied longitudinally or beyond a defined life stage like pregnancy. Using data from the Bachpan cohort of mother-infant dyads in Pakistan, we investigated female agency and depression at two life stages: perinatal (third trimester to 6-months postpartum; n = 1154) and beyond (3- to 4-years postpartum). Modified Poisson models estimated adjusted prevalence ratios (PR) for probable depression (PHQ-9) associated with female agency (freedom of movement and participation in household decision-making) at the two life stages.

The generation time, representing the interval between infections in primary and secondary cases, is essential for understanding and predicting the transmission dynamics of seasonal influenza, including the real-time effective reproduction number (Rt). However, comprehensive generation time estimates for seasonal influenza, especially since the 2009 influenza pandemic, are lacking. We estimated the generation time utilizing data from a 7-site case-ascertained household study in the United States over two influenza seasons, 2021/2022 and 2022/2023.

Renal Tubular Acidosis: Core Curriculum 2025.

Am J Kidney Dis

January 2025

Division of Nephrology and Hypertension, Department of Medicine, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina.

Renal tubular acidoses (RTAs) are a subset of non-anion gap metabolic acidoses that result from complex disturbances in renal acid excretion. Net acid excretion is primarily accomplished through the reclamation of sodium bicarbonate and the buffering of secreted protons with ammonia or dibasic phosphate, all of which require a series of highly complex and coordinated processes along the renal tubule. Flaws in any of these components lead to the development of metabolic acidosis and/or a failure to compensate fully for other systemic acidoses.

Background: People with subclinical atrial fibrillation are at increased risk of stroke, albeit to a lesser extent than those with clinical atrial fibrillation, leading to an ongoing debate regarding the benefit of anticoagulation in these individuals. In the ARTESiA trial, the direct-acting oral anticoagulant apixaban reduced stroke or systemic embolism compared with aspirin in people with subclinical atrial fibrillation, but the risk of major bleeding was increased with apixaban. In a prespecified subgroup analysis of ARTESiA, we tested the hypothesis that people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack, who are known to have an increased risk of recurrent stroke, would show a greater benefit from oral anticoagulation for secondary stroke prevention compared with those without a history of stroke or transient ischaemic attack.
