3D-printed patient-specific instrumentation and the freehand technique in high-tibial osteotomy: A prospective cohort-comparative study in an outpatient setting.

Purpose: Tibial valgus osteotomy has shown to be a successful and cost-effective procedure. The advent of image processing and three-dimensional (3D) printing is an interesting tool for achieving more accurate and reproducible results. The aim of our study was to compare the accuracy of the conventional technique and the use of customized guides in the correction of tibial deformities in tibial varus patients, the surgical and clinical benefits, and the impact of treatment in the outpatient setting.

A widespread and ancient bacterial machinery assembles cytochrome OmcS nanowires essential for extracellular electron transfer.

Microbial extracellular electron transfer (EET) drives various globally important environmental phenomena and has biotechnology applications. Diverse prokaryotes have been proposed to perform EET via surface-displayed "nanowires" composed of multi-heme cytochromes. However, the mechanism that enables only a few cytochromes to polymerize into nanowires is unclear.

COVID-19: Training activities, adherence, and use of personal protective equipment in Primary Health Care.

Objective: to analyze the association between participation in training activities and the adherence to and use of personal protective equipment by workers and professionals involved in Health Residency Programs in Primary Health Care during the COVID-19 pandemic.

Methods: a cross-sectional study in Brazil between August/2020 and March/2021. We utilized the EPI-APS COVID-19 instrument and its adapted version for resident professionals.

Stem Cell-Based Therapies for Glaucoma Treatment: A Review Bridging the Gap in Veterinary Patients.

Retinal diseases are characterized by progressive damage to retinal cells, leading to irreversible vision loss. Among these, glaucoma stands out as a multifactorial neurodegenerative disease involving elevated intraocular pressure, retinal ganglion cell apoptosis, and optic nerve damage, ultimately resulting in blindness in both humans and dogs. Stem cell-based therapies have emerged as a promising therapeutic option for such conditions due to their regenerative and neuroprotective potential.
