Impact of COVID-19 Diagnosis on Weight Trajectories of Children in the US National COVID Cohort Collaborative.

Background: The COVID-19 pandemic has exacerbated the obesity epidemic, with both adults and children demonstrating rapid weight gain during the pandemic. However, the impact of having a COVID-19 diagnosis on this trend is not known.

Methods: Using longitudinal data from January 2019 to June 2023 collected by the US National Institute for Health's National COVID Cohort Collaborative (N3C), children (age 2-18 years) with positive COVID-19 test results (n=11,474, 53% male, mean [SD] age 5.

High-throughput evaluation of half-metallicity of CoMnSi Heusler alloys using composition-spread films and spin-integrated hard X-ray photoelectron spectroscopy.

We demonstrate high-throughput evaluation of the half-metallicity of CoMnSi Heusler alloys by spin-integrated hard X-ray photoelectron spectroscopy (HAXPES) of composition-spread films performed with high-brilliance synchrotron radiation at NanoTerasu, which identifies the optimum composition showing the best half-metallicity. Co Mn Si composition-spread thin films for  = 10-40% with a thickness of 30 nm are fabricated on MgO(100) substrates using combinatorial sputtering technique. The 2-ordering and (001)-oriented epitaxial growth of CoMnSi are confirmed by X-ray diffraction for  = 18-40%.

Utility of Abdominal Radiographs After Posterior Spinal Fusion for Neuromuscular Scoliosis.

Postoperative ileus, the temporary cessation of gastrointestinal motility leading to accumulation of fluid and gas in the bowel, is a common complication following posterior spine fusion (PSF) in patients with neuromuscular scoliosis (NMS). Abdominal radiographs (KUBs) are often ordered to differentiate between ileus and mechanical obstruction but expose patients to radiation, add cost, and may lead to unnecessary work up. The aim of this study was to determine how often KUBs led to a change in treatment after PSF in patients with NMS.

The burden of headache disorders among medical students in Vietnam: estimates from a cross-sectional study with a health-care needs assessment.

Background: In our previous study, we demonstrated that headaches are highly prevalent among medical students in Vietnam. In the present study, we provide estimates of the associated symptom burden and impaired participation, utilizing these estimates to assess headache-related healthcare needs within this population.

Methods: The study followed the standardized methodology established by the Global Campaign against Headache.

Nuclear N-WASP Induces Actin Polymerization in the Nucleus with Cortactin as an Essential Factor.

Nuclear actin polymerization was reported to control different nuclear processes, but its regulation is poorly understood. Here, we show that N-WASP can trigger the formation of nuclear N-WASP/F-actin nodules. While a cancer hotspot mutant of N-WASP lacking the VCA domain (V418fs) had a dominant negative function on nuclear F-actin, an even shorter truncation mutant found in melanoma (R128*) strongly promoted nuclear actin polymerization.
