People who are higher in conscientiousness, extraversion, and agreeableness and lower in neuroticism tend to live longer. The present research tested the hypothesis that personality trait change in middle and older adulthood would also be associated with mortality risk, above and beyond personality trait level. Personality trait change may causally influence mortality risk through corresponding changes in health behaviors, social processes, and stress experience.

Objective: Alcohol use is common in older adults and linked to poor health and aging outcomes. Studies have demonstrated genetic and environmental contributions to the quantity of alcohol consumption in mid-to-late life, but less is known about whether these influences are moderated by sociodemographic factors such as age, sex, and educational attainment. This study sought to better understand sociodemographic trends in alcohol consumption across the second half of the life course and their underlying genetic and environmental influences.

The adenosine A1 receptor (AR) is a promising target for pain treatment. However, the development of therapeutic agonists is hampered by adverse effects, mainly including sedation, bradycardia, hypotension, or respiratory depression. Recently discovered molecules able to overcome this impediment are the positive allosteric modulator MIPS521 and the A1R-selective agonist BnOCPA, which are both potent and powerful analgesics with fewer side effects.

Unlabelled: Although evidence-based treatments for Prolonged Grief Disorder (PGD) exist, pretreatment characteristics associated with differential improvement trajectories have not been identified. To identify clinical factors relevant to optimizing PGD treatment outcomes, we used unsupervised and supervised machine learning to study treatment effects from a double-blinded, placebo-controlled, randomized clinical trial. Participants were randomized into four treatment groups for 20 weeks: citalopram with grief-informed clinical management, citalopram with prolonged grief disorder therapy (PGDT), pill placebo with PGDT, or pill placebo with clinical management.

Playing video games, especially games with action-based mechanics, is correlated with better cognitive performance, yet these performance advantages may originate from intrinsic factors such as earlier life cognitive differences. We investigated whether gaming-cognition associations in a sample past young adulthood remain robust after accounting for adolescent cognitive functioning. Using data from the Colorado Adoption/Twin Study of Lifespan behavioral development and cognitive aging (CATSLife; N = 1241, M = 33.

While cancer is a leading cause of death worldwide, significant disparities exist in care access in low‑ and middle‑income countries (LMICs). In Liberia, screening and treatment for anal cancers remain limited, and are exacerbated among vulnerable groups, including men who have sex with men (MSM). Screen‑triage‑treat models for cancerous lesions have been successful in reducing cervical cancer mortality, but the feasibility of this approach has not been studied for anal cancers in a low‑resource context.

Article Synopsis
  • Bullous emphysema is a chronic lung disease marked by the presence of large air spaces called bullae, with giant bullae being particularly significant and often requiring surgical removal known as bullectomy.
  • A 35-year-old man with a history of COVID-19 experienced chest pain and difficulty breathing, leading to the discovery of a giant bulla in his left lung on imaging scans.
  • Remarkably, after monitoring over several months, the giant bulla spontaneously resolved without surgery, suggesting that infectious processes may play a role in this phenomenon, highlighting the importance of careful imaging and follow-up in similar cases.

Introduction: Over 100 million displaced people rely on health services in humanitarian contexts, defined as unstable or transitory settings created in response to complex emergencies. While services are often described, there is a dearth of evidence on best practices for successful implementation to guide efforts to optimize health delivery. Implementation science is a promising but underutilized tool to address this gap.

As the numbers of older adults continue to increase globally, the need for facilitating healthy aging has become critical. While a physically healthy lifestyle, including exercise and diet, is important, recent research has highlighted a major impact of psychosocial determinants of health, such as resilience, wisdom, positive social connections, and mental well-being, on whole health. This article focuses on keeping the mind and brain healthy with psychosocially active aging.

Article Synopsis
  • The study investigates high-risk neuroblastoma by analyzing primary tumor samples from the same patients at diagnosis and after chemotherapy to find persister cells that survive treatment.
  • These persister cells show resistance to chemotherapy through a combination of tumor-intrinsic and tumor-extrinsic mechanisms, which vary based on the tumor's genetic profile.
  • Identifying these cells opens up new, personalized treatment approaches aiming to specifically target and inhibit chemoresistance, potentially reducing the chances of disease recurrence.

  • Astrocyte-secreted signals play a crucial role in neurodegenerative diseases, but the impact of proinflammatory cytokines like IL-1α, TNF-α, and C1q on these signals is not well understood.
  • In our study, we discovered that these cytokines significantly reduced the secretion of astrocyte exosomes (A-Exo.) and their distribution in SOD1G93A mice, a model for amyotrophic lateral sclerosis (ALS).
  • Despite A-Exo. being non-toxic to motor neurons, they provided neuroprotection against excitotoxicity, which was hindered by cytokines and SOD1G93A expression, indicating a loss-of-function mechanism in their

Late-life depression (LLD) is often accompanied by medical comorbidities such as psychiatric disorders and cardiovascular diseases, posing challenges to antidepressant treatment. Recent studies highlighted significant associations between treatment-resistant depression (TRD) and polygenic risk score (PRS) for attention deficit hyperactivity disorder (ADHD) in adults as well as a negative association between antidepressant symptom improvement with both schizophrenia and bipolar. Here, we sought to validate these findings with symptom remission in LLD.

Background: Maternal mortality remains a persistent challenge in low- and middle-income countries, where evidence-based interventions of obstetric triage and prehospital communication remain sparse. There is limited implementation evidence for technology-based approaches to improve obstetric care in such contexts. Liberia struggles with maternal mortality, particularly in rural areas where deaths are attributable to delays from absent triage and interfacility communication.

Immigration policy, particularly regarding migrants crossing the US-Mexico border, has been a highly debated topic for years. There is a continued debate on how to maintain national security while protecting the health and dignity of migrants. In this commentary, we argue that the Biden Administration's "Proclamation on Securing the Border" issued on June 4, 2024, alongside the Department of Homeland Security (DHS) and Department of Justice's (DOJ) Interim Final Rule, poses a significant threat to the health of migrants seeking asylum at the US-Mexico border by forcing more migrants to wait in encampments in border towns.
