Gingival spatial analysis reveals geographic immunological variation in a microbiota-dependent and -independent manner.

In mucosal barriers, tissue cells and leukocytes collaborate to form specialized niches that support host-microbiome symbiosis. Understanding the spatial organization of these barriers is crucial for elucidating the mechanisms underlying health and disease. The gingiva, a unique mucosal barrier with significant health implications, exhibits intricate tissue architecture and likely contains specialized immunological regions.

Professional Master of Health Science in Laboratory Medicine: Training Clinical Laboratory Scientists in an Integrated Program at a Research-Intensive University.

A 2-year professional master of health science program at the University of Toronto provides a unique integrated educational program to train allied health science personnel to practice as physician extenders and health care professionals in two high-demand clinical laboratory disciplines, Pathologists' Assistant (PA) and Clinical Embryologist (CE). This report describes an integrated graduate program developed and delivered in a research-intensive laboratory medicine department. The core courses in fundamental biomedical science and in general medical laboratory function and operations formed the foundation on which the requisite clinical skills required to practice as a PA or CE were subsequently delivered as comprehensive CE and PA specialty courses and practicums.

Racial and ethnic differences in self-reported barriers to substance use treatment among emergency department patients.

Background And Objectives: As overdose rates rise among non-White Americans, understanding barriers to substance use disorder (SUD) treatment access by race and ethnicity is important. This study explores self-reported barriers to SUD treatment by race and ethnicity in emergency department (ED) populations.

Methods: We conducted a secondary, exploratory analysis of a randomized trial of patients not seeking SUD treatment who endorsed active drug use at six academic EDs.

Toward AI-driven neuroepigenetic imaging biomarker for alcohol use disorder: A proof-of-concept study.

Alcohol use disorder (AUD) is a disorder of clinical and public health significance requiring novel and improved therapeutic solutions. Both environmental and genetic factors play a significant role in its pathophysiology. However, the underlying epigenetic molecular mechanisms that link the gene-environment interaction in AUD remain largely unknown.

Enhancing comfort of resident physicians treating adults with intellectual and developmental disabilities by facilitating meaningful interactions.

Background: Many physicians feel uncomfortable caring for patients with intellectual and developmental disabilities (IDD). While some residency training programs include lecture content on IDD, few provide structured experiences with individuals with IDD. One strategy for improving comfort is "contact theory:" increasing interactions with "dissimilar" people can lead to decreased negative attitudes toward that population.

Gender differences in illicit drug access, use and use disorder: Analysis of National Survey on Drug Use and Health data.

Although gender differences in the prevalence of substance use disorders (SUD) have been well-characterized, little is known about when gender differences emerge along the continuum of substance use. Understanding the contribution of gender to risk at key transition points across this continuum is needed to identify potential mechanisms underlying gender differences and to inform improved gender-responsive interventions. To characterize gender differences in the progression of cannabis, cocaine, and heroin use, the current study used data from the United States-based 2015-2019 National Survey on Drug Use and Health to quantify gender differences in: (1) perceived access to drugs, (2) lifetime drug use among individuals with at least some access, and (3) past-year SUD among those who had ever used each drug.

Flow Cytometry: The Glass Is Half Full.

Accompanied by a historical perspective of the field of cytometry, this introductory chapter provides a broad view of what flow cytometry can do; hence, the glass is half full.

Valvular Heart Disease in Pregnancy.

Valvular heart disease is a common cause of peripartum cardiovascular morbidity and mortality. The hemodynamic changes of pregnancy and their impact on preexisting valvular lesions are described in this paper. Tools for calculation of maternal and fetal risk during pregnancy are also discussed.

Spinal intradural microsurgery in a nascent neurosurgical department: Lessons learned from the first 25 cases.

Background: Between 2017 and 2021, the newly established Department of Neurosurgery at Shaare Zedek Medical Center in Jerusalem, a high volume metropolitan hospital, operated on 25 intradural lesions in 24 patients (one patient had multiple tumors). In this retrospective study, we review results and lessons learned as experienced surgeons opened a new service line.

Methods: A multidisciplinary team was assembled and led by experienced neurosurgeons with skills in both microneurosurgery and complex spine care.

Lung dendritic-cell metabolism underlies susceptibility to viral infection in diabetes.

People with diabetes feature a life-risking susceptibility to respiratory viral infection, including influenza and SARS-CoV-2 (ref. ), whose mechanism remains unknown. In acquired and genetic mouse models of diabetes, induced with an acute pulmonary viral infection, we demonstrate that hyperglycaemia leads to impaired costimulatory molecule expression, antigen transport and T cell priming in distinct lung dendritic cell (DC) subsets, driving a defective antiviral adaptive immune response, delayed viral clearance and enhanced mortality.

Medical Students' Perspectives on Family Planning and Impact on Specialty Choice.

Importance: Physicians are known to delay childbearing compared with nonphysicians and to experience higher rates of age-related pregnancy complications. Delay of childbearing is more pronounced in surgical specialties, and family planning and building goals may influence specialty choice.

Objective: To assess medical students' perspectives on the development of family planning goals and the timing of family building within a medical career to elucidate how these perceptions impact their choice of specialty.

IL-15 Priming Alters IFN-γ Regulation in Murine NK Cells.

NK effector functions can be triggered by inflammatory cytokines and engagement of activating receptors. NK cell production of IFN-γ, an important immunoregulatory cytokine, exhibits activation-specific IFN-γ regulation. Resting murine NK cells exhibit activation-specific metabolic requirements for IFN-γ production, which are reversed for activating receptor-mediated stimulation following IL-15 priming.

Education of the clinical embryology laboratory professional: development of a novel program delivered in a laboratory medicine department.

Clinical embryologists are responsible for the handling, evaluation, and care of human gametes and preimplantation embryos within the context of an assisted reproductive technology laboratory. They are integral members of a team of professionals who provide care for fertility patients. Despite the increasing recognition of clinical embryologists as professionals, training requirements, continuing professional development, and appropriate credentialing have lagged in several countries.

Langerhans cells shape postnatal oral homeostasis in a mechanical-force-dependent but microbiota and IL17-independent manner.

The postnatal interaction between microbiota and the immune system establishes lifelong homeostasis at mucosal epithelial barriers, however, the barrier-specific physiological activities that drive the equilibrium are hardly known. During weaning, the oral epithelium, which is monitored by Langerhans cells (LC), is challenged by the development of a microbial plaque and the initiation of masticatory forces capable of damaging the epithelium. Here we show that microbial colonization following birth facilitates the differentiation of oral LCs, setting the stage for the weaning period, in which adaptive immunity develops.

Association between clinician specialty and prescription of preventive medication for young adults with migraine: A retrospective cohort study.

Objective: We aimed to compare the prescribing patterns of preventive medications between pediatric and adult neurologists for young adults with migraine.

Background: Although preventive medications are effective for adults with migraine, studies in children have failed to demonstrate similar efficacy. As a result, lifestyle modifications and non-pharmacological interventions are often emphasized in children.

Understanding rabbit owners' willingness to engage in disease prevention behaviors.

Rabbit hemorrhagic disease virus 2 (RHDV2) is a fatal, highly contagious pathogen that infects wild and domestic lagomorphs (rabbits and hares). RHDV2 is an important cause of disease in pet and companion rabbits, has resulted in economic losses for the commercial rabbit industry, and has caused declines of wild lagomorph populations. It is essential for domestic rabbit owners to engage in appropriate actions (e.
