Atualizações sobre a anestesia para cirurgia laparoscopica e robótica abdominal em adultos: Update on anesthesia for laparoscopic and robotic abdominal surgery in adults

A abordagem laparoscópica tornou-se o padrão de atendimento para muitos procedimentos cirúrgicos. A cirurgia robótica é tipicamente realizada por laparoscopia; preocupações anestésicas para laparoscopia convencional e cirurgia robótica são semelhantes. A laparoscopia requer insuflação de CO2 para criar espaço para visualização e manobras cirúrgicas. O aumento associado da pressão intra-abdominal, juntamente com a absorção de CO2 e os efeitos do posicionamento cirúrgico, resultam em alterações neuroendócrinas e mecânicas que afetam a função cardiopulmonar. A abordagem laparoscópica tornou-se um padrão de tratamento para muitos procedimentos cirúrgicos abdominais, comparada com a laparotomia, a laparoscopia permite incisões menores, reduz a resposta ao estresse perioperatório, reduz a dor pós-operatória e resulta em menor tempo de recuperação. A laparoscopia requer insuflação de gás intra ou extraperitoneal, geralmente dióxido de carbono (CO2), para criar espaço para visualização e manobras cirúrgicas. A cirurgia robótica geralmente é realizada por laparoscopia e é mais comumente usada para cirurgia ginecológica e urológica, embora o uso esteja se expandindo em outras especialidades. As preocupações anestésicas para pacientes submetidos à cirurgia laparoscópica e robótica diferem daquelas para pacientes submetidos à cirurgia abdominal aberta. Eles incluem os efeitos fisiológicos do pneumoperitônio, absorção de CO2 e posicionamento necessário para a cirurgia. Além disso, alguns procedimentos laparoscópicos/robóticos demoram mais do que a alternativa aberta. A laparoscopia requer a criação de um pneumoperitônio por insuflação de gás, geralmente dióxido de carbono (CO2), para abrir espaço no abdome para visualização e manipulação cirúrgica

Avaliação do conceito sobre aspectos da qualidade da água e crise hídrica dos alunos do ensino médio de Itapetim-PE/Evaluation of the concept on aspects of water quality and water crisis in high school students in Itapetim-PE

Determinadas regiões brasileiras sofrem problemas graves de escassez de água, principalmente o Nordeste. Devido ao prolongado período de seca anual, as práticas de captação e armazenamento de água para o consumo têm sido as principais formas de abastecimento hídrico em muitas comunidades. Entretanto, um problema observado é que a água armazenada perde sua qualidade devido ações antrópicas, ou até mesmo, questões naturais. Segundo o Ministério da Saúde, “toda água destinada ao consumo humano, distribuída coletivamente por meio de sistema ou solução alternativo coletiva de abastecimento de água, deve ser objeto de controle e vigilância da qualidade da água”. Portanto, é necessário haver orientação da população, principalmente de jovens e adolescentes que estão em contato direto com a educação, podendo disseminar este conhecimento em sua comunidade. O presente estudo teve como objetivo analisar a concepção de alunos do 3º ano do ensino médio de escola pública do município de Itapetim-Pe em relação à qualidade da água armazenada em suas residências. Os dados foram coletados através de um questionário semiestruturado, onde 78 alunos responderam a 15 questões. Os resultados mostraram que 49% (n=38) utilizam cisternas e caixa d’água como reservatórios. Nas questões sobre contaminação, 71% (n=55) consideram esta água adequada para o consumo, e que, segundo 51% (n=40), não seria possível a contaminação por este meio. Porém 63% (n=49) afirmaram que estes reservatórios estão livres de microrganismos patogênicos. Estes resultados apontam que os alunos mostraram-se desinformados e sem conhecimento no que diz respeito às situações presentes na realidade atual da região semiárida

Quality of UHT whole milk marketed in Pernambuco, Brazil

The objective of this study was to evaluate the physical-chemical properties and microbiological quality of Ultra-high temperature (UHT) whole milk marketed in Pernambuco state, Brazil. In total, 390 samples of UHT whole milk were purchased from commercial establishments located in the mesoregions of Pernambuco, and transported to the Laboratory of Meat and Milk Inspection at the Federal Rural University of Pernambuco. The physical-chemical analyses and the microbiological evaluations were carried out in order to meet specific legislative mandates. All 13 brands tested met the determined physical-chemical standards. However, it was found that 105 (26.9%) samples did not meet microbiological standards. It is important to highlight the need for further development of integrated actions involving the inspection bodies and the processing plants, in order to adjust the product to the quality standards established in the legislation, respecting the rights and health of consumers.The objective of this study was to evaluate the physical-chemical properties and microbiological quality of Ultra-high temperature (UHT) whole milk marketed in Pernambuco state, Brazil.

Hexapoda Yearbook (Arthropoda: Mandibulata: Pancrustacea) Brazil 2020: the first annual production survey of new Brazilian species

This paper provided a list of all new Brazilian Hexapoda species described in 2020. Furthermore, based on the information extracted by this list, we tackled additional questions regarding the taxa, the specialists involved in the species descriptions as well as the journals in which those papers have been published. We recorded a total of 680 new Brazilian species of Hexapoda described in 2020, classified in 245 genera, 112 families and 18 orders. These 680 species were published in a total of 219 articles comprising 423 different authors residing in 27 countries. Only 30% of these authors are women, which demonstrates an inequality regarding sexes. In relation to the number of authors by species, the majority of the new species had two authors and the maximum of authors by species was five. We also found inequalities in the production of described species regarding the regions of Brazil, with Southeast and South leading. The top 10 institutions regarding productions of new species have four in the Southeast, two at South and with one ate North Region being the outlier of this pattern. Out of the total 219 published articles, Zootaxa dominated with 322 described species in 95 articles. The average impact factor was of 1.4 with only seven articles being published in Impact Factors above 3, indicating a hardship on publishing taxonomic articles in high-impact journals.The highlight of this paper is that it is unprecedent, as no annual record of Hexapoda species described was ever made in previous years to Brazil.Fil: Silva Neto, Alberto Moreira.

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery

Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional studies. To address the challenges and opportunities in this rapidly evolving field, the International Society for Extracellular Vesicles (ISEV) updates its 'Minimal Information for Studies of Extracellular Vesicles', which was first published in 2014 and then in 2018 as MISEV2014 and MISEV2018, respectively. The goal of the current document, MISEV2023, is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation and characterisation of EVs from multiple sources, including cell culture, body fluids and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, this document also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 also includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. Compiling feedback from ISEV expert task forces and more than 1000 researchers, this document conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly

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
