Utilização do Ludismo Como Instrumento na Recuperação de Conteúdos Ligações Químicas

Dificuldades dos estudantes no ensino de química, que ainda é predominantemente tradicional, podem ser observadas na escola básica e necessitam ser superadas. Abordagens mais interativas e que envolvam o protagonismo do aluno podem ser alternativas viáveis e já apresentam bons resultados, pois permitem tomadas de decisões mais autônomas. Neste sentido foi desenvolvido uma proposta com 4 turmas de primeiros anos de um colégio estadual na cidade de Morrinhos – GO e a temática trabalhada foi ligações químicas, assunto escolhido pela professora, para as avaliações de recuperação. Assim, para realizar um estudo contrastando duas abordagens, duas turmas do período matutino, a abordagem trabalhada foi tradicional, já as outras duas, do período vespertino, foi proposto uma atividade lúdica. Esta atividade foi trabalhada por duas alunas do Programa Institucional de Bolsas de Iniciação à Docência (PIBID) - Química, Campus Morrinhos, do Instituto Federal Goiano (IFGoiano). Os resultados destas observações são discutidos, sendo possível algumas reflexões sobre aspectos do ludismo e o processo de ensino aprendizagem em química. Mudanças de postura, maior participação, melhor desempenho dos estudantes e responsabilidade pela própria aprendizagem são alguns dos resultados da aplicação desta atividade que precisam ser considerados

Judicialización del error de enfermería en la atención perioperativa y en la asistencia al parto y nacimiento

Objetivos: analisar os desfechos jurídicos de erros no cuidado perioperatório e na assistência ao parto e nascimento relacionados à enfermagem, sob a ótica do respaldo legal para prevenção de falhas. Métodos: estudo exploratório, documental, qualitativo, realizado com base nos casos julgados pelo Tribunal de Justiça do Estado do Paraná, disponíveis on-line até abril de 2018. Para a análise dos dados, os processos foram codificados, o desfecho judicial foi sumarizado pela gravidade do erro; depois, apresentaram-se práticas recomendadas à prevenção de cada caso. Resultados: dentre os 13 processos analisados, 8 correspondiam ao período perioperatório (principalmente queimadura por eletrocautério); e 5, à assistência de enfermagem ao parto e ao nascimento. A gravidade dos casos foi alta (n=7). O desfecho judicial da maioria dos casos (n=11) foi a condenação da instituição. Conclusões: apesar da multifatoriedade dos erros, as falhas identificadas são passíveis de prevenção, haja vista a existência de descrição de boas práticasObjectives: to analyze the legal outcomes of malpractices in perioperative care, and delivery and birth assistance related to nursing, from the perspective of legal support for malpractice prevention. Methods: an exploratory, documentary, qualitative study, based on the cases tried by the Court of Justice of the State of Paraná, available online until April 2018. For the data analysis, we codified the processes and summarized the judicial outcome by the severity of the malpractice. Then, we recommended practices for the prevention of each case we presented. Results: among the thirteen processes analyzed, eight corresponded to the perioperative period (mainly electrocautery burn), and five to nursing care for delivery and birth. The severity of the cases was high (n=7). The judicial outcome of most cases (n=11) was the conviction of the institution. Conclusions: despite the multifactorial nature of the malpractices, the identified ones are preventable since there is a description of good practices.Objetivos: analizar los desfechos jurídicos de errores en la atención perioperativa y asistencia al parto y nacimiento relacionados a enfermería, bajo la óptica del respaldo legal para prevención de errores.

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

Isolation and biochemical characterization of a gamma-type phospholipase A2 inhibitor from Crotalus durissus collilineatus snake serum

In the present work, we describe the isolation and partial structural and biochemical characterization of the first phospholipase A(2) inhibitor (gamma PLI) from Crotalus durissus collilineatus (Cdc) snake serum. Initially, the Cdc serum was subjected to a Q-Sepharose ion exchange column, producing six peaks at 280 nm absorbance (Q1-Q6). Subsequently, Q4 fraction was submitted to affinity chromatography with immobilized PLA(2) BnSP-7, a step that resulted in two fractions (NHS-1 and NHS-2). The latter contained the inhibitor, denominated gamma CdcPLI. The molecular mass of gamma CdcPLI, determined by Matrix-Assisted Laser Desorption Ionization Time-of-Flight (MALDI-TOF), was 22,340 Da. Partial sequences obtained by Edman degradation and by mass spectrometry (MALDI-TOF/TOF), showed similarity, as expected, to other related inhibitors. Circular dichroism (CD) analysis showed the presence of approximately 22% alpha helices and 29% beta sheets in the protein secondary structure. Additionally, CD studies also indicated no significant changes in the secondary structure of gamma CdcPLI when it is complexed to BpPLA(2)-TXI. On the other hand, dynamic light scattering (DLS) assays showed a temperature-dependent oligomerization behavior for this inhibitor. Biochemical analyses showed gamma CdcPLI was able to inhibit the enzymatic, cytotoxic and myotoxic activities of PLA(2)s. Structural and functional studies performed on this inhibitor may elucidate the action mechanisms of PLA(2) inhibitors. In addition, we hope this study may contribute to investigating the potential use of these inhibitors for the treatment of snakebite or inflammatory diseases in which PLA(2)s may be involved.

Genomic epidemiology reveals how restriction measures shaped the SARS-CoV-2 epidemic in Brazil

Abstract Brazil has experienced some of the highest numbers of COVID-19 infections and deaths globally and made Latin America a pandemic epicenter from May 2021. Although SARS-CoV-2 established sustained transmission in Brazil early in the pandemic, important gaps remain in our understanding of local virus transmission dynamics. Here, we describe the genomic epidemiology of SARS-CoV-2 using near-full genomes sampled from 27 Brazilian states and an adjacent country - Paraguay. We show that the early stage of the pandemic in Brazil was characterised by the co-circulation of multiple viral lineages, linked to multiple importations predominantly from Europe, and subsequently characterized by large local transmission clusters. As the epidemic progressed, the absence of effective restriction measures led to the local emergence and international spread of Variants of Concern (VOC) and under monitoring (VUM), including the Gamma (P.1) and Zeta (P.2) variants. In addition, we provide a preliminary genomic overview of the epidemic in Paraguay, showing evidence of importation from Brazil. These data reinforce the need for the implementation of widespread genomic surveillance in South America as a toolkit for pandemic monitoring and providing a means to follow the real-time spread of emerging SARS-CoV-2 variants with possible implications for public health and immunization strategies
