The COM-B model, proposed by Michie and colleagues, posits that capability (C), opportunity (O), and motivation (M) interact to generate behavior (B), offering a comprehensive framework for analyzing the conditions under which behavior occurs. While the COM-B model has been predominantly applied to health behavior interventions, we propose that it holds considerable potential for extension to positive behaviors such as volunteering. We introduce the COM-B framework to reconceptualize the occurrence of volunteering behavior, using university student volunteering as an illustrative case. We delineate the specific meanings of Capability, Opportunity, and Motivation within the volunteering context and explore conditions that enable volunteering as a behavior to occur. Regarding the Capability component, we distinguish between physical and psychological capability, emphasizing the central rol...

Este informe de consultoría ofrece un análisis exhaustivo y recomendaciones estratégicas para shoes.pe, un mercado en línea emergente para productores locales de calzado en El Porvenir, Trujillo, Perú. En primer lugar, se presenta la organización y su contexto operativo, allanando el camino para profundizar posteriormente en el problema clave. Identificando de este modo el reto principal que consiste en convencer a los productores locales de calzado para que vendan en línea a través de shoes.pe. A continuación, se lleva a cabo una revisión exhaustiva de la bibliografía, que incluye siete áreas temáticas diferentes relacionadas con la investigación establecida y las perspectivas de la industria para proporcionar una base sólida para la siguiente exploración. Seguidamente, se emplean metodologías cualitativas y cuantitativas para realizar un análisis en profundidad del pr...

Objective: To search for all the information and available evidence on infection with SARS-CoV-2, a virus that appeared during the first 4 months of 2020, and pregnancy. Methods: Systematic review in PubMed and Google Scholar databases until April 25, 2020. We searched for published articles related to pregnant women infected with SARS-CoV-2. There was no language restriction. The search was extended to the references of the articles found. Results: In pregnant women with COVID-19, more than 90% of patients evolve mildly, 2% require intensive care. One maternal death has been reported. Prematurity occurs in approximately 25% of the cases, with predominance of late preterm infants; premature rupture of membranes presents in about 9%. Perinatal mortality is lower or similar to that of the general population, and vertical transmission has not been shown. Conclusions: Obstetrician-...

Background: PD-1 inhibitors combined with chemotherapy have shown efficacy in gastric or gastro-esophageal junction cancer. We compared the efficacy and safety of pembrolizumab plus chemotherapy with placebo plus chemotherapy in participants with locally advanced or metastatic HER2-negative gastric or gastro-esophageal junction adenocarcinoma. Methods: KEYNOTE-859 is a multicentre, double-blind, placebo-controlled, randomised, phase 3 trial, done at 207 medical centres across 33 countries. Eligible participants were aged 18 years and older with previously untreated histologically or cytologically confirmed locally advanced or metastatic HER2-negative gastric or gastro-esophageal junction adenocarcinoma and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients were randomly assigned (1:1) to receive pembrolizumab or placebo 200 mg, administered intravenously every 3...

Purpose To describe benefits and toxicities of adjuvant endocrine therapies in women younger than 35 years with breast cancer (n = 582) enrolled in the Suppression of Ovarian Function Trial (SOFT) and Tamoxifen and Exemestane Trial (TEXT). Methods In SOFT, women still premenopausal after surgery with or without chemotherapy were randomly assigned to tamoxifen alone, tamoxifen plus ovarian function suppression (OFS), or exemestane plus OFS. In TEXT, all received OFS with or without concomitant chemotherapy and were randomly assigned to exemestane plus OFS or tamoxifen plus OFS. We summarize treatment efficacy, quality of life, and adherence of the cohort of women younger than 35 years in SOFT and TEXT, alongside data from the cohort of older premenopausal women. Results For 240 human epidermal growth factor receptor 2-negative patients younger than 35 years enrolled in SOFT after receivin...

Prophages can have major clinical implications through their ability to change pathogenic bacterial traits. There is limited understanding of the prophage role in ecological, evolutionary, adaptive processes and pathogenicity of Helicobacter pylori, a widespread bacterium causally associated with gastric cancer. Inferring the exact prophage genomic location and completeness requires complete genomes. The international Helicobacter pylori Genome Project (HpGP) dataset comprises 1011 H. pylori complete clinical genomes enriched with epigenetic data. We thoroughly evaluated the H. pylori prophage genomic content in the HpGP dataset. We investigated population evolutionary dynamics through phylogenetic and pangenome analyses. Additionally, we identified genome rearrangements and assessed the impact of prophage presence on bacterial gene disruption and methylome. We found that 29.5% (298) of ...
