Detection of Environmental Spread of SARS-CoV-2 and Associated Patient Characteristics.

Understanding transmission of severe acute respiratory syndrome coronavirus 2 informs infection prevention practices. Air sampling devices were placed in patient hospital rooms for consecutive collections with and without masks. With patient mask use, no virus was detected in the room.

Orthopaedic Management of Leg-length Discrepancy in Proteus Syndrome: A Case Series.

Introduction: Proteus syndrome (PS) is a rare mosaic disorder comprising asymmetric bony and soft tissue overgrowth leading to significant morbidity. Placement of growth inhibition hardware with subsequent epiphyseal arrest improves leg-length and angular deformities in pediatric patients without PS. The purpose of this study was to review the surgical approach and present outcomes, complications, and recommendations in 8 patients with PS and leg-length discrepancy (LLD).

Approach to the jewelry aficionado.

Children's and teens' frequent use of inexpensive "costume" jewelry exposes them to a variety of contact allergens. Greater use heightens the risk of developing allergic contact dermatitis, especially in the setting of body piercings. Several clinical pearls, prevention strategies, and avoidance alternatives are provided in this article to guide clinicians and patients in the management of jewelry-related allergic contact dermatitis.

Pharmacological thrombolysis for acute ischemic stroke treatment: Gender differences in clinical risk factors.

Background: In a stroke population, women have a worse outcome than men when untreated. In contrast, there is no significant difference in treated patients. In this study, we determined whether clinical variables represent a promising approach to assist in the evaluation of gender differences in a stroke population.

Testis-specific ATP synthase peripheral stalk subunits required for tissue-specific mitochondrial morphogenesis in Drosophila.

Background: In Drosophila early post-meiotic spermatids, mitochondria undergo dramatic shaping into the Nebenkern, a spherical body with complex internal structure that contains two interwrapped giant mitochondrial derivatives. The purpose of this study was to elucidate genetic and molecular mechanisms underlying the shaping of this structure.

Results: The knotted onions (knon) gene encodes an unconventionally large testis-specific paralog of ATP synthase subunit d and is required for internal structure of the Nebenkern as well as its subsequent disassembly and elongation.

Utility of self-competency ratings during residency training in family medicine education-emerging countries: findings from Japan.

Background: Family medicine education-emerging countries face challenges in demonstrating a new program's ability to train residents in womb-to-tomb care and resident ability to provide such care competently. We illustrate the experience of a new Japanese family medicine program with resident self-competency assessments.

Methods: In this longitudinal cross-sectional study, residents completed self-competency assessment surveys online during 2011-2015.

Characterization of Courtesy Stigma Perceived by Parents of Overweight Children with Bardet-Biedl Syndrome.

Background: A child's obesity is generally perceived by the public to be under the control of the child's parents. While the health consequences of childhood obesity are well understood, less is known about psychological and social effects of having an obese child on parents. We set out to characterize stigma and courtesy stigma experiences surrounding obesity among children with Bardet-Biedl syndrome (BBS), a multisystem genetic disorder, and their parents.
