Background: Biopsychosocial factors have been associated with body satisfaction/dissatisfaction and related body image concerns in adolescence; however, few studies have investigated these relationships in middle childhood, an important developmental phase for body satisfaction. This study investigated relationships between a range of biological (body mass index), psychological (child anxiety/depression, self-esteem, and self-oriented and socially prescribed perfectionism) and sociocultural (mother's body dissatisfaction and comments about child's appearance, father's body dissatisfaction and comments about child's appearance, peer teasing and child's media exposure) factors and body satisfaction cross-sectionally and longitudinally in a sample of 7- and 8-year-old children.

Methods: In this study, participants from the longitudinal Children's Body Image Development Study (in which children had been followed-up annually from 3 years old) were assessed by interview at 7 years old (Time 1; n = 293: girls = 167, boys = 126) and 8 years old (Time 2; n = 222; girls = 126, boys = 96) and their parents completed a questionnaire at each time point.

Copper oxide nanoparticles (CuONPs) offer promising antimicrobial properties against a range of pathogens, addressing the urgent issue of antibiotic resistance. This study details the synthesis of glutamic acid-coated CuONPs (GA-CuONPs) and their functionalisation on medical-grade silicone tubing, using an oxysilane bonding agent. The resulting coating shows significant antimicrobial activity against both Gram-positive and Gram-negative bacteria, including multidrug-resistant strains, while remaining non-toxic to human cells and exhibiting stable adherence, without leaching.

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.

Article Synopsis
  • This study investigates how early social support after trauma affects PTSD symptoms over time and explores specific brain regions involved in this process, such as the amygdala and ventromedial prefrontal cortex.
  • Using data from 315 participants in the AURORA study, researchers measured PTSD symptoms and perceived emotional support at multiple time points, while also conducting neuroimaging two weeks post-trauma.
  • The results show that early emotional support is linked to changes in white matter connectivity between key brain areas, but it also highlighted unexpected increased threat reactivity in the default mode network, suggesting complex neural pathways in response to social threats.

Unfortunately, survivors of traumatic stress exposure (TSE) frequently develop adverse posttraumatic neuropsychiatric sequelae (APNS) such as chronic pain and stress/depressive symptoms. Increasing evidence indicates that there is a 'window of opportunity' following TSE in which therapeutic interventions are most effective against APNS, yet mechanisms accounting for this observation are poorly understood. Here, we aimed to better understand such mechanisms by generating snapshots of the transcriptional landscape in the early aftermath of TSE across tissues and time.

Article Synopsis
  • - The study explored the use of wrist-wearable devices to track heart rate variability (HRV) as potential biomarkers for recovery from adverse neuropsychiatric effects following traumatic events, specifically in a socioeconomically disadvantaged group.
  • - Researchers monitored participants within 72 hours of a traumatic event and over a course of 6 months, validating HRV characteristics linked to various posttraumatic symptoms, such as pain, re-experiencing, and anxiety.
  • - The findings indicate that changes in HRV could effectively predict improvements or worsening in symptoms, suggesting that these wearable technologies could serve as useful screening tools for identifying posttraumatic stress in high-risk populations.

Article Synopsis
  • - The study investigates sex/gender differences in PTSD by examining 16 risk factors and their impact on PTSD severity in a group of 2,924 acutely traumatized individuals.
  • - It finds that six risk factors are more prevalent in women, while none are more pronounced in men, highlighting unique pathways contributing to PTSD severity based on sex assigned at birth.
  • - The results indicate different risk mechanisms for men and women, suggesting that understanding these differences can help develop targeted mental health interventions and inform future research on other mental disorders.

There is a lack of consensus on the optimal antibiotic regimen for pediatric appendicitis, and conflicting data exist regarding the need for extended-spectrum use in this population. We implemented an antibiotic stewardship program with a standard, preferred antibiotic regimen for both uncomplicated and complicated appendicitis and hypothesized that clinical outcomes would be equivalent. This is a single-institution, retrospective study of pediatric patients (≤18 y) who underwent appendectomy for acute appendicitis between October 2015 and May 2022.
