Resumo Os estudos de tendência sobre a via de nascimento no Brasil têm revelado um cenário de sucessivos aumentos lineares nas proporções de cesariana. Entretanto, a possibilidade de mudanças na evolução temporal da via cirúrgica não tem sido considerada. Dessa forma, objetivou-se verificar possíveis pontos de inflexão na proporção de cesarianas no Brasil, macrorregiões e unidades federativas, bem como estimar suas projeções para o ano de 2030. Utilizou-se a série temporal com as cesarianas notificadas no Departamento de Informática do SUS no período de 1994 a 2019. Foram utilizados modelos autorregressivos integrados de médias móveis e de regressão joinpoint para obtenção de projeções e de tendências das proporções de cesariana, respectivamente. As proporções de cesarianas apresentaram tendência significativa de aumento ao longo dos 26 anos de estudo em todos os níveis de agregação. Por outro lado, quando se considera a formação de segmentos, observa-se tendência de estabilização no país e nas regiões Sul e Centro-Oeste, a partir de 2012. Norte e Nordeste apresentaram tendência de aumento e o Sudeste, de queda significativa. Projeções indicam que no ano de 2030, 57,4% dos nascimentos no país ocorrerão por via cirúrgica e que nas regiões Sudeste e Sul, serão observadas proporções superiores a 70%.

Abstract Trend studies on the model of birth in Brazil show a scenario of successive linear increases in cesarean rates. However, they ignore possible changes in the temporal evolution of this delivery modality. Thus, this study aimed to evaluate possible inflection points in cesarean rates in Brazil, its macro-regions, and federated units, as well as to estimate projections for 2030. A time series with information on cesarean sections from 1994 to 2019 from the SUS Department of Informatics was used. Autoregressive integrated moving average and joinpoint regression models were used to obtain cesarean rate projections and trends, respectively. Caesarean rates showed a significant upward trend over the 26 study years at all levels of aggregation. On the other hand, when considering the formation of segments, a stabilization trend was observed both in the country and in the South and Midwest regions, starting in 2012. Rates tended to increase in North and Northeast and significantly decrease in Southeast. Projections show that in 2030, 57.4% of births in Brazil will be cesarean, with rates higher than 70% in Southeast and South regions.

ABSTRACT Objective To analyze the clinical and sociodemographic characteristics and survival of individuals with severe acute respiratory syndrome due to COVID-19 according to the COVID-19 vaccination schedule, Brazil, 2021-2022. Methods This was a cohort study based on data from the Influenza Epidemiological Surveillance Information System; the Kaplan-Meier and Survival Tree methods were used to analyze survival. Results Among the 559,866 hospitalized cases, a higher proportion of vaccinated individuals was found among female (15.0%), elderly people aged ≥ 80 (34.5%), people from the Southeast region (15.7%), those who did not undergo respiratory support (21.2%) and those who did progress to death (15.2%); the survival curve showed that risk of death for unvaccinated individuals was higher in all age groups (p-value < 0.001); elderly people aged ≥ 80, who did not undergo mechanical ventilation and who had a booster dose had lower risk when compared to their peers who had two doses or were unvaccinated (hazard ratio = 0.64; 95%CI 0.62;0.67). Conclusion Lowest risk of death was found in vaccinated individuals, especially those who had two doses or a booster dose as well.

BACKGROUND The knowledge about eicosanoid metabolism and lipid droplet (LD) formation in the Leishmania is very limited and new approaches are needed to identify which bioactive molecules are produced of them. OBJECTIVES Herein, we compared LDs and eicosanoids biogenesis in distinct Leishmania species which are etiologic agents of different clinical forms of leishmaniasis. METHODS For this, promastigotes of Leishmania amazonensis, L. braziliensis and L. infantum were stimulated with polyunsaturated fatty acids (PUFA) and LD and eicosanoid production was evaluated. We also compared mutations in structural models of human-like cyclooxygenase-2 (GP63) and prostaglandin F synthase (PGFS) proteins, as well as the levels of these enzymes in parasite cell extracts. FINDINGS PUFAs modulate the LD formation in L. braziliensis and L. infantum. Leishmania spp with equivalent tissue tropism had same protein mutations in GP63 and PGFS. No differences in GP63 production were observed among Leishmania spp, however PGFS production increased during the parasite differentiation. Stimulation with arachidonic acid resulted in elevated production of hydroxyeicosatetraenoic acids compared to prostaglandins. MAIN CONCLUSIONS Our data suggest LD formation and eicosanoid production are distinctly modulated by PUFAS dependent of Leishmania species. In addition, eicosanoid-enzyme mutations are more similar between Leishmania species with same host tropism.

ABSTRACT Objective: There is no consensus as to the best criterion for the evaluation of metabolic syndrome (MS), impairing the estimation of its prevalence. This study aims to compare MS estimates using three recommended definitions for adolescents based on a cross-sectional study nested in the Consortium of Brazilian Birth Cohorts in São Luís, Maranhão. Subjects and methods: A total of 2,515 adolescents aged between 18 and 19 years were evaluated. The criteria of International Diabetes Federation (IDF) and National Cholesterol Education Program Panel III (NCEP-ATP) modified by Cook and cols. (2003) and De Ferranti and cols. (2004) defined SM. To compare the estimates of MS prevalence, the chi-square, Fisher’s exact and Cohen’s Kappa index tests were used. Results: Among the 2,064 participants evaluated in the final sample. The prevalence of MS ranged from 4.2% (95% CI: 3.3-5.1) to 10.2% (95% CI: 8.8-11.4). When comparing the estimates of MS prevalence in the total sample and by sex, a statistically significant difference was observed. The agreement between the criteria ranged from 0.42 (CI 95%: 0.35-0.49) to 0.55 (CI 95%: 0.48-0.62) in the total sample, 0.33 (CI 95%: 0.24-0.42) to 0.59 (95%CI: 0.47-0.71) among boys and 0.39 (95% CI: 0.26-0.52) to 0.54 (95% CI: 0.44-0.64) among girls. Conclusion: Different criteria provide different estimates for the prevalence of MS in adolescents, reflecting the importance of establishing a consensus.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

ABSTRACT Some studies have shown that secondary infections during the COVID-19 pandemic may have contributed to the high mortality. Our objective was to identify the frequency, types and etiology of bacterial infections in patients with COVID-19 admitted to an intensive care unit (ICU) and to evaluate the results of ICU stay, duration of mechanical ventilation (MV) and in-hospital mortality. It was a single-center study with a retrospective cohort of patients admitted consecutively to the ICU for more than 48 h between March and May 2020. Comparisons of groups with and without ICU- acquired infection were performed. A total of 191 patients with laboratory-confirmed COVID-19 were included and 57 patients had 97 secondary infectious events. The most frequent agents were Acinetobacter baumannii (28.9%), Pseudomonas aeruginosa (22.7%) and Klebsiella pneumoniae (14.4%); multi-drug resistance was present in 96% of A. baumannii and in 57% of K. pneumoniae. The most prevalent infection was ventilator-associated pneumonia in 57.9% of patients with bacterial infections, or 17.3% of all COVID-19 patients admitted to the ICU, followed by tracheobronchitis (26.3%). Patients with secondary infections had a longer ICU stay (40.0 vs. 17 days; p < 0.001), as well as a longer duration of MV (24.0 vs 9.0 days; p= 0.003). There were 68 (35.6%) deaths overall, of which 27 (39.7%) patients had bacterial infections. Among the 123 survivors, 30 (24.4%) had a secondary infections (OR 2.041; 95% CI 1.080 - 3.859). A high incidence of secondary infections, mainly caused by gram-negative bacteria has been observed. Secondary infections were associated with longer ICU stay, MV use and higher mortality.

BACKGROUND Patients with severe coronavirus disease 2019 (COVID-19) often present with coagulopathies and have high titres of circulating antibodies against viral proteins. OBJECTIVES Herein, we evaluated the association between D-dimer and circulating immunoglobulin levels against viral proteins in patients at different clinical stages of COVID-19. METHODS For this, we performed a cross-sectional study involving patients of the first wave of COVID-19 clinically classified as oligosymptomatic (n = 22), severe (n = 30), cured (n = 27) and non-infected (n = 9). Next, we measured in the plasma samples the total and fraction of immunoglobulins against the nucleoprotein (NP) and the receptor-binding domain (RBD) of the spike proteins by enzyme-linked immunosorbent assay (ELISA) assays. FINDINGS Patients with severe disease had a coagulation disorder with high levels of D-dimer as well as circulating IgG against the NP but not the RBD compared to other groups of patients. In addition, high levels of D-dimer and IgG against the NP and RBD were associated with disease severity among the patients in this study. MAIN CONCLUSIONS Our data suggest that IgG against NP and RBD participates in the worsening of COVID-19. Although the humoral response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is partially understood, and more efforts are needed to clarify gaps in the knowledge of this process.

ABSTRACT Introduction: There is evidence regarding the inverse relationship between adherence to the Mediterranean diet and the development of chronic conditions such as coronary heart disease, metabolic syndrome and diabetes. Objective: To determine the factors associated with adherence to the Mediterranean diet in patients attended in a Peruvian medical center. Methods: Cross-sectional analytical study in 209 patients attended at a medical center in Lima, Peru. The PREDIMED questionnaire was used to measure adherence to Mediterranean diet. Correlation between the Mediterranean diet adherence score and the covariates, age, sex, hypertriglyceridemia, hypercholesterolemia, fasting hyperglycemia and nutritional diagnosis was investigated. General linear models were used. Results: Of 209 participants, the majority were male (79.9 %) and the median age was 31 years. The 20.2 % had obesity, those who presented alterations in triglycerides were 29.1 %, cholesterol (21.7 %) and fasting glycemia (26.8 %). As for the PREDIMED score, the mean was 4.6 points. It was found that fasting hyperglycemia (Coef. = -2.08) had a negative association with the Mediterranean diet adherence score. Conclusion: Adherence to the Mediterranean diet pattern is low, and is negatively correlated with hyperglycemia findings in the participants evaluated.

RESUMEN Introducción: Existen evidencias respecto a la relación inversa, entre la adherencia a la dieta mediterránea y el desarrollo de padecimientos crónicos como enfermedad coronaria, síndrome metabólico y diabetes. Objetivo: Determinar los factores bioquímicos asociados a la adherencia a la dieta mediterránea, en pacientes atendidos en un centro médico peruano. Métodos: Estudio transversal en 209 pacientes atendidos en un centro médico de Lima, Perú. Se utilizó el cuestionario PREDIMED para medir la adherencia a la dieta mediterránea. Se indagó la correlación entre el puntaje de adherencia a la dieta mediterránea y las covariables, edad, sexo, hipertrigliceridemia, hipercolesterolemia, hiperglicemia en ayunas y diagnóstico nutricional. Se utilizaron modelos lineales generales. Resultados: De 209 participantes, la mayoría fueron hombres (79,9 %) y la mediana de edad fue de 31 años. El 20,2 % tenía obesidad, quienes presentaron alteraciones en triglicéridos, fueron el 29,1 %, colesterol (21,7 %) y glicemia en ayunas (26,8 %). En cuanto al puntaje del PREDIMED, la media fue de 4,6 puntos. Se encontró que la hiperglicemia en ayunas (Coef. = -2,08) tuvo asociación negativa con el puntaje de adherencia a la dieta mediterránea. Conclusión: La adherencia al patrón de dieta mediterránea es baja, y se correlaciona de forma negativa con hallazgos de hiperglicemia en los participantes evaluados.

RESUMO Os canabinoides compreendem os endocanabinoides, fitocanabinoides e os canabinoides sintéticos e desempenham ações no sistema nervoso central e periférico. Uma quantidade enorme de publicações tem sido lançada nos últimos anos, embora a cannabis seja conhecida por milênios. Os Departamentos Científicos da Academia Brasileira de Neurologia descreveram as evidências do uso médico em suas áreas. A literatura está em constantes mudanças e possíveis novas evidências podem surgir nos próximos dias ou meses. A prescrição dessas substâncias deve ser discutida com os pacientes e suas famílias, com conhecimento sobre eventos adversos e sua eficácia.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

Resumo Tobias de Lacerda Martins Moscoso (1879-1928) foi um engenheiro brasileiro que transitou pelas áreas da estatística, matemática e economia política. Professor da Escola Politécnica da Universidade do Rio de Janeiro, teve, contudo, seu nome ofuscado na historiografia brasileira pelo acidente aéreo que o vitimou, em 1928. Apesar de sua morte precoce, Moscoso viria a ser, em 1930, o único latino-americano entre os destinatários da carta-convite enviada por Fisher, Frisch e Roos para a reunião inaugural da Econometric Society. Este artigo busca, então, cumprir dois objetivos: recuperar o nome de Tobias Moscoso na historiografia brasileira e apresentar a trajetória que o levou a integrar o grupo de oitenta e três indivíduos convidados para a fundação da Econometric Society. Argumenta-se que o convite a Moscoso se alicerça sobre dois pilares: sua abordagem à economia política, que privilegiava os métodos quantitativos, e sua visita aos círculos acadêmicos parisienses, em 1926.

Abstract Tobias de Lacerda Martins Moscoso (1879-1928) was a Brazilian engineer who worked on statistics, mathematics, and political economy. Despite his professorship at the Polytechnic School of the University of Rio de Janeiro, Moscoso had his name overshadowed in the Brazilian historiography by the air crash that killed him, in 1928. Notwithstanding his premature death, Moscoso was, in 1930, the only Latin American among the addressees of the invitation letter sent by Fisher, Frisch, and Roos to the founding meeting of the Econometric Society. This paper, therefore, aims at fulfilling two objectives: recovering Tobias Moscoso’s name in the Brazilian historiography and presenting the trajectory that made him one of the individuals among the eighty-three invitees for the foundation of the Econometric Society. The paper argues that the invitation Moscoso received was based on two pillars: his approach to political economy, which favored quantitative methods, and his visit to the Parisian academic circles, in 1926.

Lipid droplets (LDs; lipid bodies) are intracellular sites of lipid storage and metabolism present in all cell types. Eukaryotic LDs are involved in eicosanoid production during several inflammatory conditions, including infection by protozoan parasites. In parasites, LDs play a role in the acquisition of cholesterol and other neutral lipids from the host. The number of LDs increases during parasite differentiation, and the biogenesis of these organelles use specific signaling pathways involving protein kinases. In addition, LDs are important in cellular protection against lipotoxicity. Recently, these organelles have been implicated in eicosanoid and specialised lipid metabolism. In this article, we revise the main functions of protozoan parasite LDs and discuss future directions in the comprehension of these organelles in the context of pathogen virulence.

Abstract The pegmatites of the São João del Rei Pegmatitic Province are related to the Siderian protoliths of the Cassiterita and Resende Costa orthogneisses and to the Ritápolis metagranitoid of Ryacian age. Chemical analysis of garnet from twelve pegmatites reveal two different types of grains, which were found in the same pegmatitic body in six of these samples. One garnet type has almandine-spessartine composition (Sps11-7-58.8 Alm36.8-86.5 Prp0.1-4.1Grs0.0-1.4Adr0.0-2.6), grains with orange and pink tones, and scarce mineral inclusions. These garnet grains may have been formed at the magmatic stage of pegmatite crystallization. The composition of these grains plot exclusively on the Alm-Sps axis at the Prp+Grs+Adr+Uvr × Alm × Sps diagram, as expected from garnet crystallized in pegmatites, and an expansion of the field associated to pegmatites is proposed. The second type has a distinct chemical composition (Sps26.9-84.8Alm3.6-40.0 Prp0.0-10.4 Grs9.3-45.6 Adr0.1-3.4), displaying enrichment in Ca. This Ca-enriched garnet has irregular shaped colourless grains and abundant mineral inclusions. These grains may have been formed by Ca-metasomatism during the late-stage crystallization of the pegmatites.

Resumo: En | Texto: En | PDF: En

In the present study, we investigated the genetic diversity of Plasmodium vivax metacaspase 1 (PvMCA1) catalytic domain in two municipalities of the main malaria hotspot in Brazil, i.e., the Juruá Valley, and observed complete sequence identity among all P. vivax field isolates and the Sal-1 reference strain. Analysis of PvMCA1 catalytic domain in different P. vivax genomic sequences publicly available also revealed a high degree of conservation worldwide, with very few amino acid substitutions that were not related to putative histidine and cysteine catalytic residues, whose involvement with the active site of protease was herein predicted by molecular modeling. The genetic conservation presented by PvMCA1 may contribute to its eligibility as a druggable target candidate in vivax malaria.
