Vitamin D-VDR and vitamin A-RAR affect IL-13 and IFNγ secretion from human CD4 T cells directly and indirectly via competition for their shared co-receptor RXR.

The effects of vitamin D and vitamin A in immune cells are mediated through the vitamin D receptor (VDR) and retinoic acid receptor (RAR), respectively. These receptors share the retinoid X receptor (RXR) co-factor for transcriptional regulation. We investigated the effects of active vitamin D (1,25(OH)D) and 9-cis retinoic acid (9cRA) on T helper (T)1 and T2 cytokines and transcription factors in primary human blood-derived CD4 T cells.

An Interpersonal and Meta-analytic Approach to Parenting Behaviors and Adolescent Sleep.

Two dimensions of parenting behaviors-affiliative/non-affiliative and autonomy/control- are each consistently linked to adolescent sleep health. Parenting behaviors that facilitate good sleep likely involve affiliation (i.e.

The scheduling of adolescence with Netrin-1 and UNC5C.

Dopamine axons are the only axons known to grow during adolescence. Here, using rodent models, we examined how two proteins, Netrin-1 and its receptor, UNC5C, guide dopamine axons toward the prefrontal cortex and shape behaviour. We demonstrate in mice () that dopamine axons reach the cortex through a transient gradient of Netrin-1-expressing cells - disrupting this gradient reroutes axons away from their target.

A Work in Progress: Women's Status in the Plastic Surgery Workforce and Recommendations for Success.

Only 20% of the current plastic surgery workforce is female, but since 2022 most matched applicants in integrated plastic surgery programs have been women. The aim of this study was to examine current practice models among female plastic surgeons, including those outside of academia, as the field continues to evolve. In this study we surveyed female plastic surgeons in different practice models to elicit perspectives, career path advice, characterize and project trends, and provide recommendations for success.

Electrical Burn and Amputations in a Burn Center in Addis Ababa, Ethiopia.

Background: Burn injuries are a global public health problem and continue to be one of the leading causes of unintentional death and injury. Electrical injuries, a relatively rare cause of burns, are increasingly being reported with higher rates of mortality in low and middle-income countries due to rapid industrialization in the absence of safety regulations. Electrical burn injuries can result in death, various organ system dysfunctions, or limb amputations.

Utility of RNA Expression to Determine the Tissue of Origin of Malignancies with an Inconclusive Histopathology.

We present 2 cases of cancer of unknown origin in which RNA-based cancer classification testing provided vital insight and directed treatment management. The tissue of origin could not be determined in both of these patients utilizing morphology and immunohistochemical analysis of the tissue samples. Next-generation sequencing and tumor-of-origin testing using an RNA-based molecular cancer classifier were performed to elucidate the possible tissue of origin.

Do Computerized Tomography Scans Change Management in Carpometacarpal Dislocations and Fracture-Dislocations?

Background: Concomitant carpal injuries with dislocations and fracture-dislocations of the carpometacarpal joints (CMCD/FD) are often hard to see on plain radiographs, making advanced imaging a useful diagnostic adjunct. We aim to: (1) characterize bony injury patterns with CMCD/FD; and (2) determine the frequency that preoperative computed tomography (CT) scans change surgical management.

Methods: A retrospective review was performed of patients who underwent operative fixation of CMCD/FD from 2006 to 2021.

Transmission of Lung Adenocarcinoma From a Single Donor in 2 Transplant Recipients: A Case Report With Literature Review.

Malignancies transmitted to recipients during solid organ transplants carry significant morbidity and mortality. We present 2 cases of adenocarcinoma of donor lung origin transmitted via liver and kidney transplant from a single donor. Both recipients developed metastatic adenocarcinoma of lung origin with p.

Simultaneous detection of DNA variation and methylation at HLA class II locus and immune gene promoters using targeted SureSelect Methyl-Sequencing.

The Human Leukocyte Antigen (HLA) locus associates with a variety of complex diseases, particularly autoimmune and inflammatory conditions. The HLA-DR15 haplotype, for example, confers the major risk for developing Multiple Sclerosis in Caucasians, pinpointing an important role in the etiology of this chronic inflammatory disease of the central nervous system. In addition to the protein-coding variants that shape the functional HLA-antigen-T cell interaction, recent studies suggest that the levels of HLA molecule expression, that are epigenetically controlled, also play a role in disease development.

Game Changers: Plastic and Reconstructive Surgery Innovations of the Last 100 Years.

Background: Innovation is an essential aspect of plastic and reconstructive surgery (PRS), whether it involves improving current processes or implementing radical change that disrupts the status quo. Collaborating and sharing innovations help advance the field of PRS as a whole.

Methods: An anonymous survey was administered to members of the American Association of Plastic Surgeons on their opinions of the top five innovations in PRS of the last 100 years.

Evaluation of Cell-Specific Epigenetic Age Acceleration in People With Multiple Sclerosis.

Background And Objectives: In multiple sclerosis (MS), accelerated aging of the immune system (immunosenescence) may be associated with disease onset or drive progression. DNA methylation (DNAm) is an epigenetic factor that varies among lymphocyte subtypes, and cell-specific DNAm is associated with MS. DNAm varies across the life span and can be used to accurately estimate biological age acceleration, which has been linked to a range of morbidities.

Affiliative Parent-Adolescent Bedtime and Waketime Interactions are Associated with Adolescent Sleep.

Objectives: The current study examined whether evening and morning affiliation (i.e., warmth) and autonomy (i.

Rehabilitation Outcomes in Children With Acute Flaccid Myelitis From 2014 to 2019: A Multicenter Retrospective Review.

Background: Acute flaccid myelitis (AFM) is a childhood illness characterized by sudden-onset weakness impairing function. The primary goal was to compare the motor recovery patterns of patients with AFM who were discharged home or to inpatient rehabilitation. Secondary analyses focused on recovery of respiratory status, nutritional status, and neurogenic bowel and bladder in both cohorts.

To Operate or Not to Operate? Reconstructive Surgical Burden and Quality of Life of Pediatric Patients with Facial Differences.

Objective: The Craniofacial Condition Quality of Life Scale (CFC-QoL) was used to evaluate the relationship between surgical burden and quality of life (QoL).

Design: Patient-parent dyads completed the CFC-QoL which queries the following QoL domains: Bullying, Peer Problems, Psychological Impact, Family Support, Appearance Satisfaction, and Desire for Appearance Change. Stepwise multivariate linear regressions were performed for each QoL domain.

Selective Androgen Receptor Modulators (SARMs)-Induced Liver Injury: A Case Report and Review of Literature.

Drug-induced liver injury (DILI) is one of the leading causes of death from acute liver failure (ALF) in the United States, accounting for approximately 13% of ALF cases in the United States. Selective androgen receptor modulators (SARMs) were first developed to increase muscle mass while avoiding the side effects of conventional androgenic steroids. Although not Food and Drug Administration (FDA) approved, they are widely available online and are consumed to enhance athletic performance.

Age-specific determinants of psychiatric outcomes after the first COVID-19 wave: baseline findings from a Canadian online cohort study.

Background: Canadians endured unprecedented mental health (MH) and support access challenges during the first COVID-19 wave. Identifying groups of individuals who remain at risk beyond the acute pandemic phase is key to guiding systemic intervention efforts and policy. We hypothesized that determinants of three complementary, clinically actionable psychiatric outcomes would differ across Canadian age groups.

Dopamine axons are the only axons known to grow during adolescence. Here, using rodent models, we examined how two proteins, Netrin-1 and its receptor, UNC5C, guide dopamine axons towards the prefrontal cortex and shape behaviour. We demonstrate in mice ( ) that dopamine axons reach the cortex through a transient gradient of Netrin-1 expressing cells - disrupting this gradient reroutes axons away from their target.

Cardiovascular Disease Assessment Prior to Kidney Transplantation.

Cardiovascular disease is highly prevalent and the leading cause of mortality in patients with chronic kidney disease, end-stage kidney disease, and kidney transplantation. However, kidney transplantation offers improved survival and quality of life, with an overall reduction in cardiovascular disease events; therefore, it remains the optimal treatment choice for those with advanced kidney disease. Pretransplantation cardiovascular assessment is performed prior to wait-listing and at routine intervals with the principal goal of screening for asymptomatic cardiac disease, intervening when necessary to improve long-term patient and allograft survival.

Epigenetic clock indicates accelerated aging in glial cells of progressive multiple sclerosis patients.

Background: Multiple sclerosis (MS) is a chronic inflammatory neurodegenerative disease of the central nervous system (CNS) characterized by irreversible disability at later progressive stages. A growing body of evidence suggests that disease progression depends on age and inflammation within the CNS. We aimed to investigate epigenetic aging in bulk brain tissue and sorted nuclei from MS patients using DNA methylation-based epigenetic clocks.
