Little research focuses on physical health outcomes of traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) among post-9/11 women veterans (WVs). This study examined lifetime TBI, current PTSD, and their associations with biomarkers of cardiometabolic health, sleep, pain, and functional disability among post-9/11 WVs. WVs ( = 90) from the Translational Research Center for TBI and Stress Disorders longitudinal cohort study were included in this study.

Article Synopsis
  • Multiple Primary Renal Tumours (MPRT)
  • : Some patients with renal tumours have multiple primary lesions, particularly seen in certain inherited cancer syndromes, which warrant thorough clinical and genetic assessments for underlying disorders.
  • Demographics and Characteristics
  • : A review of 7,689 patients revealed that MPRT is more common in younger males, with 32.4% diagnosed before age 46, and 61.1% of cases being synchronous. Higher rates of similar histology and multiple papillary RCC (16.1%) were also documented.
  • Genetic Associations and Management
  • : 14.9% of MPRT patients reported a family cancer history, notably with von

Over 20 million Americans are living with a substance use disorder (SUD) and nearly 100,000 die annually from drug overdoses, with a majority involving an opioid. Many people with SUD have co-occurring chronic pain and/or a mental health disorder. Exercise is a frontline treatment for chronic pain and is an effective strategy for reducing depression and anxiety and improving overall mental health.

Wilms tumour (nephroblastoma) is a renal embryonal tumour that is frequently caused by constitutional variants in a small range of cancer predisposition genes. TRIM28 has recently been identified as one such gene. Previously, observational data strongly suggested a parent of origin effect, whereby Wilms tumour only occurred following maternal inheritance of a pathogenic genetic variant.

Objective: Head injury and strangulation are highly prevalent in intimate partner violence (IPV) contexts, but there is little research examining the potential implications of these injuries on physical health and functional status. This pilot study explored the extent to which injury type (head injury, strangulation) and severity (no injury, subconcussive head injury, traumatic brain injury; no strangulation, strangulation, strangulation with loss of consciousness) were associated with biomarkers of cardiometabolic health and self-reported functioning among female survivors of IPV.

Methods: Participants were 51 individuals assigned female at birth who experienced IPV during their lifetime and screened positive for probable posttraumatic stress disorder (PTSD) on the PTSD Checklist for DSM-5 (average age = 32.

This study examined sex-specific associations between sexual violence (SV) type and physical activity, and identified associations between PTSD symptoms and physical activity, all among cisgender men and women survivors of SV. Cross-sectional data from men (n = 197) and women (n = 356) survivors of SV were analyzed with stratified (men; women) hierarchical logistic regressions. Additionally, fully adjusted models for the total sample included interaction terms to further assess whether associations between SV type as well as PTSD symptoms (sum, clusters) and physical activity differed significantly by sex.

Article Synopsis
  • - This study explored how SARS-CoV-2 spreads within households, focusing on the role of children and their adult caregivers, particularly examining whether children mostly contracted the virus from symptomatic adults, especially mothers.
  • - Conducted in Brazil from April 2020 to July 2022, the study involved 1,256 participants across 298 households, revealing that children are less likely to transmit the virus compared to adults, especially if the adult is symptomatic or unvaccinated.
  • - Findings highlighted that vaccinated adults not only had a lower chance of severe illness but also reduced the risk of infecting their household members, suggesting implications for similar urban populations in Latin America.

Objective: Veterans can present at nongovernment (Department of Defense, Department of Veterans Affairs) mental health agencies with complex symptom constellations that frequently include posttraumatic stress disorder, depression, and generalized anxiety. To date, no veteran study has validated these measures on a treatment-seeking sample of veterans outside the DoD and VA.

Methods: We used a treatment-seeking sample of veterans ( N = 493) to validate measures that assess these constructs (PTSD Checklist 5, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7).

This study assessed the feasibility of implementing screening, brief intervention and referral (SBIR) intervention in hospital settings. This cross-sectional study evaluated the implementation of the SBIR intervention in a hospital in Alberta for tobacco use, alcohol intake, physical inactivity, and insufficient vegetable and fruit consumption. Patients were interviewed approximately 4-month later to collect data on the acceptability and effectiveness of the intervention received ( = 108).

Introduction: Military service members disproportionately experience sexual violence (SV) and its related health concerns. Although recent work has shown physical activity to be an effective strategy for improving physical and mental health among trauma-exposed military populations, little of this work has focused specifically on military service members with a history of SV. To address these gaps in knowledge and practice, this study identified the most salient perceived benefits/barriers of exercise among men and women survivors of SV with military affiliations.

Around 95% of patients with clinical features that meet the diagnostic criteria for von Hippel-Lindau disease (VHL) have a detectable inactivating germline variant in VHL. The VHL protein (pVHL) functions as part of the E3 ubiquitin ligase complex comprising pVHL, elongin C, elongin B, cullin 2 and ring box 1 (VCB-CR complex), which plays a key role in oxygen sensing and degradation of hypoxia-inducible factors. To date, only variants in VHL have been shown to cause VHL disease.

Background: Trauma exposure and posttraumatic stress are highly prevalent and comorbid with health problems. Despite the apparent systemic nature of post-traumatic stress, recommended treatments neglect trauma's deleterious effects on health. Integrative mind-body treatments for posttraumatic stress, such as Tai Chi and Qigong (TCQ), may offer a promising adjunct to first-line treatments.

Multi-locus Inherited Neoplasia Allele Syndrome (MINAS) refers to individuals with germline pathogenic variants in two or more cancer susceptibility genes(CSGs). With increased use of exome/genome sequencing it would be predicted that detection of MINAS would become more frequent. Here we review recent progress in knowledge of MINAS.
