Objective: Natural variation in ovarian steroid hormones across the female lifespan contributes to an increased risk for depressive and posttraumatic stress disorder (PTSD) symptoms in women. However, minimal work has focused on understanding the impacts of reproductive aging on the brain and behavioral health of trauma-exposed women. This systematic review examines the bidirectional relationship between trauma-related psychopathology and reproductive aging.

Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age-0+ parr, 1033 smolts detected migrating downstream in spring, and 99 adults detected returning from their first marine migration to the River Frome (Dorset, UK) to investigate the influence of smolt biological characteristics on their migration timing and maiden marine sojourn duration. Age-specific differences in the influence of smolt length on migration timing were found, with longer 1-year-old smolts emigrating later than their shorter counterparts within the same age class, but the opposite association existed for 2-year-old smolts.

This study examined the chemoselectivity and diastereoselectivity of silyl nitronate alkenyn-nitroethers in Intramolecular Silyl Nitronate Cycloadditions (ISNCs) to produce isoxazole derivatives with interesting medicinal properties. These reactions resulted in the formation of either dihydrofuro[3,4-c]isoxazolines/isoxazolidines and/or alkynyl moieties attached to 2,5-dihydrofuryl carbonyls. This study also discerned the diastereoselectivities of the resulting cyclic adducts and compared them to previous findings.

Article Synopsis
  • A 2-year-old girl developed a growing bruise-like mass in her eye socket months after an orbital injury, which was diagnosed through CT imaging as possible soft tissue contusion or hematoma.
  • Surgical removal was performed, and lab tests revealed it was an orbital varix, showing CD34+ endothelium.
  • This case is unique as it represents the first documented instance of posttraumatic orbital varix formation in children.

Background: Current clinical sequencing methods cannot effectively detect DNA methylation and allele-specific variation to provide parent-of-origin information from the proband alone. Parent-of-origin effects can lead to differential disease and the inability to assign this in de novo cases limits prognostication in the majority of affected individuals with retinoblastoma, a hereditary cancer with suspected parent-of-origin effects.

Methods: To directly assign parent-of-origin in retinoblastoma patients, genomic DNA was extracted from blood samples for sequencing using a programmable, targeted single-molecule long-read DNA genomic and epigenomic approach.

Humans show remarkable differences in social behaviour between families, groups, communities and cultures, whereas such group-level within-species variation in socio-behavioural propensities is typically overlooked in other species. Studies on intraspecific variation in animal social structures are needed to inform an evolutionary account of human sociality. Here, we study multiple independent bonobo populations ( = 6) in zoological settings to investigate if and how bonobos ( = 70) show group-specific signatures in sociality.

The activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare. Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their environment and indicate welfare concerns. Changes in the housing environment in particular may have critical influences on behaviour and welfare.

Background: Chronic pain following traumatic stress exposure (TSE) is common. Increasing evidence suggests inflammatory/immune mechanisms are induced by TSE, play a key role in the recovery process versus development of post-TSE chronic pain, and are sex specific. In this study, we tested the hypothesis that the inflammatory marker C-reactive protein (CRP) is associated with chronic pain after TSE in a sex-specific manner.

Introduction: Identification and reporting of severe adverse events (SAEs) during anesthesia care remains critical in identifying areas of improvement in perioperative patient care. Although many healthcare organizations rely on the self-reporting of SAEs, under-reporting may limit the identification of the true incidence of these events. To circumvent these barriers, many healthcare systems leverage the Electronic Medical Record (EMR) by incorporating an Anesthesia Information Management System (AIMS).

Background: Egg-based inactivated quadrivalent seasonal influenza vaccine (eIIV4), cell culture-based inactivated quadrivalent seasonal influenza vaccine (ccIIV4), and recombinant haemagglutinin (HA)-based quadrivalent seasonal influenza vaccine (RIV4) have been licensed for use in the USA. In this study, we used antigen-specific serum proteomics analysis to assess how the molecular composition and qualities of the serological antibody repertoires differ after seasonal influenza immunisation by each of the three vaccines and how different vaccination platforms affect the HA binding affinity and breadth of the serum antibodies that comprise the polyclonal response.

Methods: In this comparative, prospective, observational cohort study, we included female US health-care personnel (mean age 47·6 years [SD 8]) who received a single dose of RIV4, eIIV4, or ccIIV4 during the 2018-19 influenza season at Baylor Scott & White Health (Temple, TX, USA).

Purpose: Adolescent and young adults (AYA) with breast cancer, compared to older adults, are diagnosed with more aggressive cancers, at more advanced stages and may undergo more aggressive treatment but have worse survival. Despite this, no research has studied the effects of the receipt of National Comprehensive Cancer Network (NCCN) defined guideline-concordant care (GCC) for breast cancer on AYA survival. We examined the association of GCC with survival among young adult (20-39 years old) breast cancer survivors.
