Clinical validation of 3D-printed swabs in adults and children for SARS-CoV-2 detection.

Throughout the entire coronavirus disease 19 (COVID-19) pandemic, there were disruptions in the supply chain of test materials around the world, primarily in poor- and middle-income countries. The use of 3D prints is an alternative to address swab supply shortages. In this study, the feasibility of the clinical use of 3D-printed swabs for oropharyngeal and nasopharyngeal sampling for the detection of SARS-CoV-2 infection was evaluated.

Groin Flap for Reconstruction of Traumatic Degloving Hand Injury: A Report of 5 Cases.

Degloving is a type of avulsion injury that leads to the separation of the skin from its underlying tissues. It is usually caused by industrial machinery through smashing or traction mechanisms, where the patient typically tries to avoid severe trauma by pulling their hand off, resulting in this particular injury. Although free flaps have now become the standard of treatment in many institutions, the lack of this possibility makes pedicled flaps a good reconstructive option, with advantages such as low donor-site morbidity, low procedure costs, and relatively easy dissection of the flap.

Topical Antimicrobial Agents for the Prevention of Burn-Wound Infection. What Do International Guidelines Recommend? A Systematic Review.

Background: Choosing adequate topical antimicrobial agents in burn patients still represents a challenge. Therefore, this systematic review was conducted to compile and evaluate current recommendations in international clinical practice guidelines (CPGs) to develop more consistent clinical guidance.

Methods: A systematic search for CPGs was conducted independently by two reviewers using PubMed, EMBASE, Google Scholar, and external citations.

Validation of 3D-Printed Swabs for Sampling in SARS-CoV-2 Detection: A Pilot Study.

In this pilot study, we characterize and evaluate 3D-printed swabs for the collection of nasopharyngeal and oropharyngeal secretion samples for the SARS-CoV-2 detection. Swabs are made with the fused deposition modeling technique using the biopolymer polylactic acid (PLA) which is a medical-grade, biodegradable and low-cost material. We evaluated six swabs with mechanical tests in a laboratory and in an Adult Human Simulator performed by healthcare professionals.

Exposure to bisphenol A: current levels from food intake are toxic to human cells.

In the present work, cell lines of different origin were exposed to BPA levels from food intake reported elsewhere. Specifically, we used an in vitro assay to determine cytotoxicity of BPA in three cell lines: MCF7 (breast cancer), PC3 (prostate cancer) and 3T3-L1 (mouse fibroblast). Cytotoxic effects were observed at concentrations higher than 50 μg/mL which is above the involuntary exposure level of BPA described before in fresh, canned and frozen foods and beverages.

Environmental epigenomics: Current approaches to assess epigenetic effects of endocrine disrupting compounds (EDC's) on human health.

Environmental Epigenomics is a developing field to study the epigenetic effect on human health from exposure to environmental factors. Endocrine disrupting chemicals have been detected primarily in pharmaceutical drugs, personal care products, food additives, and food containers. Exposure to endocrine-disrupting chemicals (EDCs) has been associated with a high incidence and prevalence of many endocrine-related disorders in humans.

[Metformin increases serum concentration of high molecular weight (HMW-adiponectin) in nondiabetic obese subjects].

Introduction: Obesity is associated with low-intensity chronic systemic inflammation.

Objective: To evaluate the efficacy of two different doses of metformin in comparison with placebo on increased serum levels of high molecular weight (HMW) adiponectin.

Material And Methods: An experimental design was developed with a crossover complete treatment and balanced design; 28 female and eight male nondiabetic obese adults participated.

Assessment of medical residents' satisfaction.

Background: Modern medical education is focused on students, and it is necessary to assess its level of satisfaction. A questionnaire was validated and we then conducted a study about the educational satisfaction level of medical residents of the Hospital General of Mexico.

Methods: An observational, descriptive, cross-sectional and prospective study was conducted.

[A foot in the future].

This project won the First Edition 2007 VAC Therapy Prize. This project tells the story of a woman suffering from lesions in her left leg and running a fever whose prognosis was complicated. The article describes the nurses' evaluation of the patient's lesions, skin sores, and the application of a treatment plan using nursing diagnoses and the satisfactory treatment with negative topical pressure.
