Although deep learning (DL) has demonstrated impressive diagnostic performance for a variety of computational pathology tasks, this performance often markedly deteriorates on whole slide images (WSI) generated at external test sites. This phenomenon is due in part to domain shift, wherein differences in test-site pre-analytical variables (e.g.

Unlabelled: The global COVID-19 pandemic has disrupted the lives of workers and taken its toll on health and well-being. In line with recent calls for more inductive and abductive occupational health science research, we exploratorily meta-analyzed workers' COVID-19 distress, defined as psychological and psychosomatic strain contextualized to experiencing the virus and pandemic broadly. We identified many existing COVID-19 distress measures (e.

Background: Correctional workers are at high risk for exposure to trauma, both as direct violence and as threats to their safety and well-being. The distress associated with these critical incidents (CIs) affects mental and physical health. Current tools are limited for detecting CIs in this workforce and are therefore insufficient for addressing correctional worker trauma.

Introduction: The differential diagnosis of lesions excised to exclude melanoma include a variety of benign and malignant melanocytic and non-melanocytic lesions.

Objectives: We examined the variability between pathologists in diagnosing non-melanocytic lesions.

Methods: As part of a larger study prospectively examining the diagnosis of lesions excised to exclude melanoma in 198 patients at a primary care skin cancer clinic in Newcastle, Australia, we compared diagnosis made by 5 experienced dermatopathologists, of 44 non-melanocytic lesions in 44 patients aged 22-90.

Background/objectives: Pathology laboratories are required to determine or estimate the measurement uncertainty for all quantitative results, but there is no literature on the uncertainty in margin measurements for skin cancer excisions.

Methods: Six pathologists measured 4-14 histological margins in each of 10 basal cell carcinoma.

Results: The mean of measurements from all the margins from all the cases was 1.

Importance: The proposed MOLEM (Management of Lesion to Exclude Melanoma) schema is more clinically relevant than Melanocytic Pathology Assessment Tool and Hierarchy for Diagnosis (MATH-Dx) for the management classification of melanocytic and nonmelanocytic lesions excised to exclude melanoma. A more standardized way of establishing diagnostic criteria will be crucial in the training of artificial intelligence (AI) algorithms.

Objective: To examine pathologists' variability, reliability, and confidence in reporting melanocytic and nonmelanocytic lesions excised to exclude melanoma using the MOLEM schema in a population of higher-risk patients.

Introduction: This study assessed well-being in physical therapy (PT) students, sources of stress, and career attitudes. Studies of students in health care programs have found that these students experience higher levels of stress and anxiety compared to age- and gender-matched peers.

Subjects: Pre-professional and professional PT students from a Midwestern University in Spring 2018 (n = 253) and 2019 (n = 232).

The purpose of this study was to describe the prevalence of and relationships among disordered eating, food insecurity, and weight status among transgender and gender nonbinary youth and young adults. This cross-sectional study involved a screening protocol to assess disordered eating and food insecurity risk from September to December of 2019 at a gender clinic using five validated measures: (1) previous eating disorder diagnosis (yes/no); (2) Sick, Control, One Stone, Fat, Food Questionnaire (SCOFF); (3) Adolescent Binge Eating Disorder Questionnaire (ADO-BED); (4) Nine-Item Avoidant/Restrictive Food Intake Disorder Screen (NIAS); and (5) Hunger Vital Sign. Age, assigned sex at birth, gender identity, stage of medical transition, and body mass index were collected.

Tumor stage and grade, visually assessed by pathologists from evaluation of pathology images in conjunction with radiographic imaging techniques, have been linked to outcome, progression, and survival for a number of cancers. The gold standard of staging in oncology has been the TNM (tumor-node-metastasis) staging system. Though histopathological grading has shown prognostic significance, it is subjective and limited by interobserver variability even among experienced surgical pathologists.

Importance: Jail officers are an underserved population of public safety workers at high risk for developing chronic mental health conditions.

Objective: In response to national calls for the examination of stressors related to the unique work contexts of correctional facilities, we implemented a pilot study informed by the Total Worker Health (TWH) strategy at two urban and two rural jails.

Design: Participatory teams guided areas of interest for a mixed-data needs assessment, including surveys with 320 jail officers to inform focus groups (N = 40).

Objective: The aim of this study was to explore posttraumatic stress disorder (PTSD) symptom prevalence and health characteristics among jail correctional officers, a generally understudied population of public safety workers.

Method: A Conservation of Resources (COR)-inspired framework explored relationships to PTSD symptoms among jail officers (N = 320) employed in Midwest US jails.

Results: More than half (53.

We present a case of acquired elastotic hemangioma (AEH), a rare, benign vascular tumor. A Caucasian male in his 60s presented with an asymptomatic, solitary, non-pigmented and violaceous lesion of short duration on the dorsum of his hand. The lesion had unique clinical, dermatoscopic and pathological features.
