In this study, single voxel proton magnetic resonance spectroscopic imaging ((1)H-MRS) and volumetric analysis of hippocampal magnetic resonance imaging (MRI) images were used to determine if any differences in hippocampal biochemistry or volume were present between former prisoners of war (POWs) with and without posttraumatic stress disorder (PTSD) and control subjects matched for age and education. This study did not find lower hippocampal concentrations of N-acetylaspartate (NAA), smaller hippocampal volumes, or more impaired memory function in older veterans with PTSD compared with a group matched for traumatic experience or a nontraumatized control group.

Poland suffered an epidemic of louse-borne typhus from 1916-1923, with 400,000 cases and more than 130,000 deaths. The causative factors were depressed economic conditions and a refugee crisis that engulfed Poland after World War I. The recognition of the epidemic in 1919 stimulated the creation of the League of Red Cross Societies (LRCS).

Systematic Review of Surgical Care in the Incarcerated Population: Identifying Knowledge Gaps for Future Research.
Ann Surg Open
June 2024
From the Surgical Health Outcomes and Reaching for Equity (SHORE), Department of Surgery, University of Rochester Medical Center, Rochester, NY.
Article Synopsis
- This study systematically reviews the current state of surgical care for incarcerated individuals in the U.S., highlighting significant gaps in knowledge and care quality that need addressing in future research.
- The U.S. prison population, which largely consists of young, low-income men from minority backgrounds, faces unique health challenges that are compounded by limited access to healthcare and a lack of literature on their surgical needs.
- The review found that most studies focused on orthopedic surgeries, revealing issues such as delayed hospital visits and high complication rates for incarcerated patients compared to their nonincarcerated counterparts, indicating a need for improved surgical practices and follow-ups in this demographic.
Game-theoretic agent-based modelling of micro-level conflict: Evidence from the ISIS-Kurdish war.

This article delves into the dynamics of a dyadic political violence case study in Rojava, Northern Syria, focusing on the conflict between Kurdish rebels and ISIS from January 1, 2017, to December 31, 2019. We employ agent-based modelling and a formalisation of the conflict as an Iterated Prisoner's Dilemma game. The study provides a nuanced understanding of conflict dynamics in a highly volatile region, focusing on microdynamics of an intense dyadic strategic interaction between two near-equally- powered actors.
