Avaliação toxicológica da preparação fitoterápica contendo Piper methysticum ...

A Kava kava ( Piper methysticum Forst), pertencente à família das Piperaceae, é utilizada para diminuir a ansiedade e medo e tratar distúrbios comportamentais. É um fitoterápico utilizado em vários países, entretanto pouco se sabe, sobre seus efeitos no desenvolvimento embrionário. O presente trabalho avaliou o possível efeito teratogênico da formulação fitoterápica contendo Piper methysticum Forst durante o período de organogênese em ratas Wistar. As ratas foram tratadas com 0mg.kg –1 (controle), 5mg.kg –1 ; 35mg.kg –1 e 50mg.kg –1 da preparação fitoterápica, por via oral, do 6° ao 21° dia de prenhez. Os resultados revelaram ausência de toxicidade sistêmica e reprodutiva nas variáveis avaliadas, fundamentados pela ausência de alterações no desenvolvimento ponderal, consumos de ração e água, na massa relativa dos órgãos, nas reabsorções embrionárias, na massa corporal, na vitalidade, no número de fetos por progenitora e nas alterações macroscópicas externas e esqueléticas dos fetos. Adicionalmente as enzimas alanina aminotrasferase (ALT) e fosfatase alcalina (FA) foram determinadas no soro das ratas tratadas, para avaliar o possível efeito hepatotóxico da preparação fitoterápica. Não houve alteração das enzimas ALT e FA, bem como alterações histopatólógicas do fígado das ratas, não confirmando a hepatotoxicidade. Conclui-se que o fitoterápico kava kava, nas doses testadas, não determina o aparecimento de teratogenicidade

Objetivo: Realizar análise descritiva da situação do aleitamento materno em crianças menores de quatro meses do município de Macaé/ RJ. Métodos: Estudo epidemiológico descritivo, retrospectivo, utilizando o Sistema de Informação da Atenção Básica (SIAB), disponível no sítio eletrônico do Departamento de Informática do Sistema Único de Saúde (DATASUS). Foram utilizadas as seguintes variáveis: crianças menores de 4 meses em aleitamento materno misto e crianças menores de 4 meses em aleitamento materno exclusivo, residentes no município de Macaé, no período de 2005 a 2015. O recorte temporal escolhido foram os últimos 10 anos consolidados no DATASUS. Resultados: O número de crianças cadastradas e amamentadas no município durante o período estudado mostra que, em todos os anos, o percentual se manteve estável para todas as variáveis estudadas. A prática de AME sofreu pouca variação com o menor percentual observado de 68% em 2011 e com um valor máximo de 75%, em 2013. O percentual de aleitamento misto se manteve entre 24% e 29%, enquanto o percentual de crianças não amamentadas ficou entre 1% a 3%. Conclusões: Existem evidências suficientes para afirmar que o apoio à amamentação é necessário para aumentar a duração e a exclusividade da amamentação, garantindo múltiplas vantagens à saúde de recém-nascidos a termo e pré-termo, crianças, mães e sociedade em geral

ANESTESIA EM CÃO COM HEMOPERITÔNIO POR RUPTURA DE HEMANGIOSSARCOMA ESPLÊNICO

Hemangiosarcoma is a common tumor in dogs and a frequent cause of hemoperitoneum in small animal practice. In this emergency, quick diagnosis and focus on hemostasis are inecessary. Thus, damage control techniques and team organization for surgery can be used, including the use of blood components, permissive hypotension technique, and antifibrinolytic drugs like tranexamic acid, all of these to reduce bleeding and maintain tissue perfusion. Therefore, this study aims to report the anesthesia of a patient with hemoabdomen due to splenic mass rupture, later diagnosed as moderately differentiated hemangiosarcoma, discussing the drugs used and complications during the procedure, as well as the actions taken to reduce bleeding before and during surgical hemostasis.O Hemangiossarcoma é um tumor comum em cães e é causa frequente de hemoperitônio na clínica de pequenos animais. Na emergência de hemoperitônio faz-se necessário rápido diagnóstico e ações que visem a hemostasia, podendo-se lançar mão de técnicas de contenção de danos até organização da equipe para cirurgia, como utilização de hemocomponentes, da técnica de hipotensão permissiva e do fármaco antifibrinolítico ácido tranexâmico, visando diminuir o sangramento e manter perfusão tecidual. O objetivo desse trabalho é relatar a anestesia de uma paciente com hemoabdômen, por rompimento de massa esplênica, posteriormente diagnosticada como Hemangiossarcoma moderadamente diferenciado, discorrendo-se sobre os fármacos utilizados, intercorrências ocorridas ao longo do procedimento, bem como as ações tomadas para diminuir a perda sanguínea antes e durante a hemostasia cirúrgica

CoronaVac vaccine is effective in preventing symptomatic and severe COVID-19 in pregnant women in Brazil: a test-negative case-control study.

BACKGROUND: More doses of CoronaVac have been administered worldwide than any other COVID-19 vaccine. However, the effectiveness of COVID-19 inactivated vaccines in pregnant women is still unknown. We estimated the vaccine effectiveness (VE) of CoronaVac against symptomatic and severe COVID-19 in pregnant women in Brazil. METHODS: We conducted a test-negative design study in all pregnant women aged 18-49 years with COVID-19-related symptoms in Brazil from March 15, 2021, to October 03, 2021, linking records of negative and positive SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR) tests to national vaccination records. We also linked records of test-positive cases with notifications of severe, hospitalised or fatal COVID-19. Using logistic regression, we estimated the adjusted odds ratio and VE against symptomatic COVID-19 and against severe COVID-19 by comparing vaccine status in test-negative subjects to test-positive symptomatic cases and severe cases. RESULTS: Of the 19,838 tested pregnant women, 7424 (37.4%) tested positive for COVID-19 and 588 (7.9%) had severe disease. Only 83% of pregnant women who received the first dose of CoronaVac completed the vaccination scheme. A single dose of the CoronaVac vaccine was not effective at preventing symptomatic COVID-19. The effectiveness of two doses of CoronaVac was 41% (95% CI 27.1-52.2) against symptomatic COVID-19 and 85% (95% CI 59.5-94.8) against severe COVID-19. CONCLUSIONS: A complete regimen of CoronaVac in pregnant women was effective in preventing symptomatic COVID-19 and highly effective against severe illness in a setting that combined high disease burden and marked COVID-19-related maternal deaths

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants

Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt
