RESUMO

Introduction Meningiomas have been described as slow-growing neoplasms with benign behavior derived from the connective tissue surrounding the brain and spinal cord. Meningiomas represent one-third of primary central nervous system (CNS) tumors. The World Health Organization (WHO) initially classified them into three groups based on their histopathological characteristics, recently incorporating molecular patterns. Small cohorts have been reported in Latin America compared to the international literature. Ignoring the epidemiology of meningiomas in this region and considering this limitation, we aim to study the epidemiology of meningiomas in our country, Mexico. Material and methods A historical cohort was carried out on 916 patients diagnosed with intracranial meningiomas from January 2008 to January 2021, considering sociodemographic, topographic, and histopathological characteristics. Results In this study, 69.4% (n=636) of patients were women with a mean overall age of 47.53 (SD=14.85) years; 79.6% (n=729) of the lesions were supratentorial with convexity meningiomas being the most prevalent at 32.6% (n=299). Histopathologically, transitional (45.7%) (n=419), meningothelial (22.1%) (n=202), and fibroblastic (16.7%) (n=153) meningiomas were the most frequent. We found significant differences between men and women in age (p=0.01), infra or supratentorial presentation (p<0.001), location of the lesion (p<0.001), and histopathological characteristics (p<0.001). Conclusions Our results are consistent with what has been reported; however, until now, it appears as the largest series reported in our country and Latin America.

RESUMO

The manufacture of pharmaceutical products made under good manufacturing practices (GMP) must comply with the guidelines of national regulatory bodies based on international or regional compendia. The existence of this type of regulation allows pharmaceutical laboratories to count on the standardization of high-quality production processes, obtaining a safe product for human use, with a positive impact on public health. In addition, the COVID-19 pandemic highlights the importance of having more and better-distributed manufacturing plants, emphasizing regions such as Latin America. This review shows the most important GMP standards in the world and, in particular, their relevance in the production of vaccines and antibodies.

RESUMO

Primary pediatric brain tumors comprise a broad group of neoplasm subtypes that can be categorized based on their histological and molecular features according to the 2016 World Health Organization (WHO) classification of central nervous system (CNS) tumors. The majority of the pediatric brain tumors demonstrate a singular preference for this age group and have a unique molecular profile. The separation of certain tumor entities, including different types of embryonal tumors, low-grade gliomas, and high-grade gliomas, may have a significant impact by guiding appropriate treatment for these children and potentially changing their outcomes. Currently, the focus of the imaging diagnostic studies is to follow the molecular updates, searching for potential imaging patterns that translate this information in molecular profile results, therefore helping the final diagnosis. Due to the high impact of accurate diagnosis in this context, the scientific community has presented extensive research on imaging pediatric tumors in recent years. This article summarizes the key characteristics of the imaging features of the most common primary childhood brain tumors, categorizing them according to the recent WHO classification update, which is based on each of their molecular profiles. The purpose of this review article is to familiarize radiologists with their key imaging features and thereby improve diagnostic accuracy.

RESUMO

Abstract Economic development and good health depended on access to clean water and sanitation. Therefore, because economic development and good health depended on access to clean water and sanitation, beginning in the early 1970s the World Bank, the World Health Organization (WHO), and others began a period of sustained interest in developing both for the billions without either. During the 1980s, two massive and wildly ambitious projects showed what was possible. The International Drinking Water Supply and Sanitation Decade and the Blue Nile Health Project aimed for nothing less than the total overhaul of the way water was developed. This was, according to the WHO, "development in the spirit of social justice."

Resumo Crescimento econômico e boa saúde dependem de acesso a saneamento e água limpa. Assim, o Banco Mundial, a Organização Mundial da Saúde (OMS) e outros órgãos, a partir do início da década de 1970, inauguraram um período de contínuo interesse no desenvolvimento de ambos para bilhões de pessoas desprovidas de tais necessidades. Durante a década de 1980, dois projetos monumentais e extremamente ambiciosos demonstraram o que era viável fazer. A International Drinking Water Supply and Sanitation Decade e o Blue Nile Health Project visavam à total reestruturação do modelo de desenvolvimento da água. Tratava-se, segundo a OMS, do "desenvolvimento do espírito de justiça social".

RESUMO

Abstract Hospitals and other health facilities generate an ever-increasing amount of waste, approximately 15% of which may be infectious, toxic, or radioactive. The World Health Organization has been addressing the issue since the 1980s. After initially focusing on high-income countries, it then focused on low-income countries, with unsafe disposal methods in landfills and inadequate incinerators as major concerns. Gradually, the understanding of the issue has undergone several shifts, including from a focus on the component of medical waste considered "hazardous" to all forms of waste, and from accepting medical waste as a necessary downside of high-quality healthcare to seeing the avoidance of healthcare waste as a component of high quality healthcare.

Resumo Hospitais e outros centros de tratamento de saúde geram um volume de resíduos cada vez maior, dos quais cerca de 15% podem ser infecciosos, tóxicos ou radioativos. A Organização Mundial da Saúde começou a enfrentar o problema na década de 1980. Inicialmente, concentrou-se nos países ricos, depois mudou o foco para os países pobres, onde métodos de eliminação inseguros, como aterros sanitários e incineradores inadequados, preocupavam. Aos poucos, a compreensão do problema passou por mudanças, inclusive do enfoque no conteúdo do resíduo hospitalar considerado "perigoso", passando para todas as formas de resíduos, e da aceitação do resíduo médico como um inconveniente inerente aos cuidados de saúde de alta qualidade, até o conceito de que evitar a produção de resíduos hospitalares faz parte dos cuidados de saúde de alta qualidade.

RESUMO

Abstract Within the framework of recent historiography about the role of the World Health Organization (WHO) in modernizing public health and the multifaceted concept of global health, this study addresses the impact of the WHO's "country programs" in Spain from the time it was admitted to this organization in 1951 to 1975. This research adopts a transnational historical perspective and emphasizes attention to the circulation of health knowledge, practices, and people, and focuses on the Spain-0001 and Spain-0025programs, their role in the development of virology in Spain, and the transformation of public health. Sources include historical archives (WHO, the Spanish National Health School), various WHO publications, the contemporary medical press, and a selection of the Spanish general press.

Resumen En el marco de la reciente historiografía sobre el papel de la Organización Mundial de la Salud (OMS) en la modernización de la salud pública y el concepto multifacético de salud global, se estudia el papel de los llamados "programas país" de la OMS en España desde su admisión en 1951 hasta 1975. Adoptando perspectiva histórica transnacional y enfatizando el estudio de la circulación de personas, conocimientos y prácticas científico-sanitarias, nuestro análisis se centra en los programas España-0001 y España-0025, en evaluar su papel en el desarrollo de la virología en España y en la transformación de la salud pública. Nuestras fuentes vienen de archivos históricos (OMS, Escuela Nacional de Sanidad), publicaciones de la OMS, revistas médicas contemporáneas, y una selección de prensa general española.

RESUMO

Globally, a quarter of the population is infected with tuberculosis (TB), caused by Mycobacterium tuberculosis. About 5-10% of latent TB infections (LTBI) progress to active disease during the lifetime. Prevention of TB and treating LTBI is a critical component of the World Health Organization's (WHO) End TB Strategy. This study aims to examine the screening practices for prevention and treatment employed by the National Tuberculosis Program of Trinidad and Tobago in comparison to the WHO's standard guidelines. A cross-sectional retrospective study was conducted from the TB registers (2018-2019) for persons aged 18 years and above with recorded tuberculin skin test reactions (TST). Bivariate comparisons for categorical variables were made using Chi-square or Fisher's exact test. Binary logistic regression was used for exploring predictors of TST positivity with adjustment for demographic confounders in multivariable models. Of the total 1972 eligible entries studied, 384 (19.4%) individuals were tested positive with TST. TB contact screening (aOR 2.49; 95% CI 1.65, 3.75) and Bacillus Calmette-Guerin (BCG) vaccination status (aOR 1.66; 95% CI, 1.24 to 2.22) were associated with a positive TST reaction, whereas, preplacement screening failed to show such association when compared to those screened as suspect cases. The findings suggest that TB contact screening and positive BCG vaccination status are associated with TST positivity independent of age and gender.

RESUMO

BACKGROUND: The International Classification of Diseases (ICD) has been grouping the allergic and hypersensitivity disorders involving the respiratory tract under topographic distribution, regardless of the underlying mechanisms, triggers or concepts currently in use for allergic and hypersensitivity conditions. In order to strengthen awareness and deliberate the creation of the new "Allergic or hypersensitivity disorders involving the respiratory tract" section of the ICD-11, we here propose make the building process public. METHODS: The new frame has been constructed to cover the gaps previously identified and was based on consensus academic reports and ICD-11 principles. Constant and bilateral discussion was kept with relevant groups representing specialties and resulted in proposals submission into the ICD-11 online platform. RESULTS: The "Allergic or hypersensitivity disorders involving the respiratory tract" section covers 64 entities distributed across five main categories. All the 79 proposals submitted resulted from an intensive collaboration of the Allergy working group, relevant Expert working groups and the WHO ICD governance. CONCLUSION: The establishment of the ICD-11 "Allergic or hypersensitivity disorders involving the respiratory tract" section will allow the dissemination of the updated concepts to be used in clinical practice by many different specialties and health professionals.
