Introducción: Los estudios del vínculo entre la exposición a información sobre salud y la adopción y mantención de conductas preventivas suelen pasar por alto que dentro del concepto “información” pueden existir distintas categorías. Objetivo: Explorar los mensajes que reciben las personas en torno a tres hábitos saludables: la práctica de actividad física, el consumo de frutas y verduras y el abandono del consumo de tabaco. Métodos: Se realizaron 36 entrevistas semiestructuradas con personas mayores de 25 años residentes en la ciudad de Santiago de Chile. Resultados: Los mensajes que las personas recuerdan haber recibido pueden organizarse en cuatro categorías: riesgos o aspectos negativos, beneficios, información práctica y prescripciones. Las personas conectan algunas categorías claramente con la adopción de comportamientos, mientras que otras parecen irrelevantes o incluso perjudiciales. Además, se advierten diferencias etarias en la recordación de distintas categorías. Conclusión: Este estudio subraya la necesidad de abrir el concepto de información sobre salud cuando se quiere estudiar su incidencia en las decisiones de salud de las personas, teniendo en cuenta que los entornos informativos de los sujetos están compuestos por distintos tipos de mensajes y que no todos ellos empujan en la dirección deseada.

Introduction: Health journalism had a key role in the COVID-19 pandemic around the world. In Brazil, the misinformation and scientific uncertainty had an impact on physical and mental health journalists. Objective: To understand the perception of journalists in the capital of Brazil about their work during the COVID-19 pandemic. Methodology: Qualitative, exploratory and descriptive research, with content analysis of online interviews with journalists who work with topics on COVID-19 during the pandemic. Results: The life and working conditions of journalists in the pandemic were changed, with the need for more caution to explain, disseminate and update people about COVID-19. There was more work, difficulties and slowness in gathering information. The home office, the use of new technologies for preparing and editing the news were also mentioned as a positive thing. Conclusion: The pandemic changed the way of Brazilian journalism, with challenges and opportunities that must be accompanied by the managers, workers and health communication researchers.

Introduction: America was the epicenter for COVID-19, suffering from 44.5% of people infected and 47.4% of deaths. Brazil, Argentina, Colombia, Peru, and Chile are among the most affected countries. Objectives: This article has chosen these countries to analyze how the risks of COVID-19 have been communicated by governments websites to citizens. Methodology: It adopted an exploratory research method with a qualitative approach to describe and evaluate the quality of government information in three dimensions: technical, content and citizen empowerment. Results: From the risk communication perspective, this research identified the inadequacy of the messages on official web pages to the most vulnerable groups and their social specificities. This paper also highlights the absence of accessibility on the contents; the shortage of digital services to serve the population. Conclusion: Government content on COVID-19 requires a dedicated website to facilitate access and guarantee citizens' right to information.

The relationship between cancer and primary immunodeficiencies, also known as inborn errors of immunity, has been studied for years. Common variable immunodeficiency exemplifies this relationship, as it is amongst the most frequent primary immunodeficiencies and the risk of malignancy is even greater when compared to others. Many hypotheses have been proposed to explain why this risk increases, which include defects in tumor immunity, chronic inflammation, genetic predisposition, genetic instability, altered clearance of viruses and bacteria, and altered microbiota. Hence, this review attempts to synthetize the evidence that is currently available on these hypotheses, in order to improve the understanding of the mechanisms that participate in the development of cancer in people with common variable immunodeficiency. To achieve this, a search for articles published between 2018 and 2023 was done, using keywords in different databases (ClinicalKey, ScienceDirect, SAGE Journals, Springer, Willey, PubMed and Google Scholar). At the end of this review it is concluded that, based on the current evidence, the mechanisms implicated in the aforementioned hypotheses are likely to act simultaneously and collaborate with each other in the processes of carcinogenesis and tumor progression. Key words: Common Variable Immunodeficiency, cancer, immunologic diseases, genetic predisposition, human microbiome. Source: DeCS/MeSH.

Pharmacometry is an interdisciplinary science that uses mathematical and statistical tools for data modeling, in order to support the development process of pharmaceutical products, as well as their safe and effective use. Biological drugs are all those that use biological sources as starting material; they are complex molecules and their pharmacokinetic modeling, as well as the set-up of safety and efficacy profiles, are complicated. This has been improved due to the current development of digital tools such as pharmacometric software, not only because they allow the optimization of treatments in the population, but also because they favor the identification of subpopulations with special characteristics. Thanks to this, the safety and efficacy of therapies is extended to people with atypical metabolizers, particular clinical cases, and drugs with a narrow therapeutic margin, in order to generate individualized dosage regimens. Although pharmacometry is an emerging branch of pharmacological knowledge, its robustness in the integration and prediction of data behavior positions it as a potential key piece in the future development of precision medicine and pharmacogenomics; even more so, if it is directed to the study of biological products. Key words: Biological Products, Therapeutic use, Pharmacometry, Individualization of Therapy. Source: DeCS/MeSH.

OHVIRA syndrome (Obstructed Hemivagina and Ipsilateral Renal Anomaly) is characterized by a uterus didelphys, a totally or partially blind hemivagina, and ipsilateral renal agenesis. This article describes three clinical cases of female patients aged 13, 12 and 11, where cyclical cramping abdominal pain was a predominant symptom, mainly associated with a progressively growing abdominal mass and urinary symptoms, irregular menstrual cycles, dysmenorrhea with pain crises that begin with the menstrual period. Other important symptoms were the following: the sensation of pelvic masses, scant and fetid menstrual flow. Likewise, all three patients were found to have ipsilateral renal agenesis. The management was a surgical approach, by means of cystoscopy, vaginoscopy and vaginoplasty with vaginal window of obstructive hemivagina. It should be noted that the surgical intervention was successful and did not present complications. The aim of this study is to give visibility to this syndrome, due to its rare presentation, low incidence and underdiagnosis. Therefore, it is relevant that health personnel become familiar with its different presentations in order to have an early diagnosis and offer timely surgical management, reduce suffering and prevent complications.

Nutcracker syndrome is a vascular abnormality in which the left renal vein is compressed as it passes between the junction of the aorta and the superior mesenteric artery. This syndrome is more common in women and is characterized by symptoms such as abdominal pain, low back pain, hematuria, and proteinuria. This paper describes two cases of adolescents, one male and the other female, who attended a nephrology outpatient clinic due to non-specific symptoms (pollakiuria and abdominal pain) accompanied by gross hematuria and persistent microscopic hematuria. For this reason, complementary studies were required and the diagnosis of nutcracker syndrome was made. In conclusion, these two cases are presented because they are a pathology of low prevalence, which makes it difficult to suspect it in the face of frequent clinical manifestations and, for this reason, it must be known, detected and treated promptly. Key words: Nutcracker Syndrome, Renal, Hematuria, Renal Vein. Source: MeSH.

Henry Gray (1827-1861), was an anatomist and surgeon at Saint George's Hospital in London, England. Gray is notable for the publication of his treatise on Anatomy, Descriptive and Surgical. This text was created in collaboration with Henry Carter, who collaborated with the anatomical dissections and also produced the illustrations in this book. Gray's Anatomy is a precisely illustrated work, which continues to be highly regarded as an authoritative textbook in the field of human anatomy, which has influenced and instructed many medical students for over 160 years. Henry Gray's career was spent at Saint Georges Hospital, from medical student to become professor of anatomy and curator of the hospital's museum. He was a member of the Royal Society and the Royal College of Surgeons. The aim of this paper is to provide a systematic  review of Henry Gray's contributions to the field of human anatomy. Key words: Anatomy, England, Medical Education, Professor. Source: DeCS/MeSH.
