Background: Guidelines recommend annual anal cytology-based squamous cell carcinoma of anus (SCCA) screening for men who have sex with men (MSM) with HIV aged ≥35 years (eligible population). Recommended threshold for high resolution anoscopy (HRA) depends on its availability: low-threshold (any abnormal cytology) if availability is high, and high-threshold (High-Grade Squamous Intraepithelial Lesion (HSIL) on cytology) if availability is low.

Methods: Retrospective chart review (2018-2022) at academic HIV clinics.

Article Synopsis
  • Some treatments called biologics can help people with severe asthma and other allergic diseases like skin issues and food allergies.
  • Dupilumab has been shown to work well for skin problems and has been approved, while Omalizumab helps with allergies but isn't approved for that use yet.
  • There are promising ideas about combining biologic therapy with other treatments for allergies, but more research is needed to confirm if they really work.

Children are regularly exposed to chemical contaminants that may influence brain development. However, relatively little is known about how these contaminants impact the developing human brain. Here, we combined silicone wristband exposure assessments with neuroimaging for the first time to examine how chemical contaminant mixtures are associated with the developing basal ganglia-a brain region key for the healthy development of emotion, reward, and motor processing, and which may be particularly susceptible to contaminant harm.

Background: Adolescence and young adulthood are vulnerable developmental periods for individuals with sickle cell disease (SCD), particularly given the impact of social inequities, challenges with transitioning to adult healthcare services, and increased risk for morbidity and mortality. Systems of power, such as institutionalized and interpersonal manifestations of bias, could impact SCD transfer and engagement in adult care through their influence on healthcare transition readiness; yet research in this area is limited.

Objective: To characterize how systems of power impact transition readiness factors described in the Social-ecological Model of AYA Readiness for Transition to Promote Health Equity (SMART-E) framework at the patient, caregiver, and practitioner levels.

The central nervous system HIV reservoir is incompletely understood and is a major barrier to HIV cure. We profiled people with HIV (PWH) and uninfected controls through single-cell transcriptomic and T cell receptor (TCR) sequencing to understand the dynamics of HIV persistence in the CNS. In PWH on ART, we found that most participants had single cells containing HIV-1 RNA, which was found predominantly in CD4 central memory T cells, in both cerebrospinal fluid (CSF) and blood.

Background: Ankylosing spondylitis (AS) is a type of chronic inflammation that is most prevalent in young adults and is characterized by an inflammatory enthesiopathy that gradually develops toward ossification and ankylosis. If inflammation is left unchecked, it can potentially lead to complications such as secondary amyloidosis, also known as AA amyloidosis, involving the deposition of amyloid serum A protein. Our case presents with a thyroid localization of AA amyloidosis which is secondary to this AS.

Objective: Emerging research suggests that completion of pediatric cancer treatment can be challenging for caregivers given shifting roles and responsibilities. Lower caregiver quality of life (QOL) has been associated with cancer-related variables, higher cancer caregiving strain, and more household material hardship during pediatric cancer treatment. Caregiver QOL at the end of treatment has not been fully investigated but has implications for child and family well-being.

Objective: End of pediatric cancer treatment requires family adjustment. Caregivers who struggle to incorporate the child's condition into family life have poorer family outcomes. To better understand factors that contribute to successful transition off active childhood cancer treatment, we sought to examine caregiver perceived management ability of the youth's condition and family functioning as predictors of caregiver distress, evaluate family functioning as a mediator between perceived ability and distress, and explore race and ethnicity as a moderator between perceived ability and family functioning.

Objective: The Pediatric Psychosocial Preventative Health Model (PPPHM) is a three-tier model of family psychosocial risk used to guide intervention approaches in pediatric healthcare settings. Screening all families to determine levels of risk supports equitable care. We review evidence from papers using the Psychosocial Assessment Tool (PAT), a brief caregiver-report measure of family psychosocial risk with scores that map to the PPPHM, to characterize the distribution of risk.

Background: Consistent with the National Institute of Nursing Research's mission of leading nursing research to address current health challenges, the new Strategic Plan identifies five research lenses: health equity, social determinants of health, population and community health, prevention and health promotion, and systems and models of care. Family research, central to nursing research and practice, is the cornerstone of social ecology and represents a critical intersection of social and structural determinants of health.

Purpose: We argue why family health is essential to the 2022-2026 Strategic Plan and how the lenses can strengthen family research.
