The impact of smoking on COVID-19-related mortality: a Brazilian national cohort study.

INTRODUCTION: Current evidence suggests the potential heightened vulnerability of smokers to severe coronavirus disease (COVID-19) outcomes. AIMS: This study aimed to analyze the clinical outcomes and mortality related to tobacco use in a cohort of hospitalized Brazilian COVID-19 patients. METHODS: This retrospective cohort study analyzed adults hospitalized for COVID-19 in Brazil using the SIVEP-Gripe database (official data reported by public and private healthcare facilities for monitoring severe acute respiratory syndrome cases in Brazil). The inclusion criteria were patients over 18 years of age with a positive RT-qPCR test for SARS-CoV-2. The analysis focused on in-hospital mortality, considering smoking as an exposure variable, and included covariates such as age, gender, and comorbidities. Smoking history was collected from the self-reported field in the database. Statistical analyses included descriptive statistics, crude Odds Ratios, and multivariable binary logistic regression. RESULTS: This study included 2,124,285 COVID-19 patients, among whom 44,774 (2.1 %) were smokers. The average age of the smokers was higher than that of the never-smokers (65.3 years vs. 59.7 years). The clinical outcomes revealed that smokers had higher rates of intensive care unit admission (51.6 % vs. 37.2 % for never-smokers), invasive ventilatory support (31.5 % vs. 20.2 % for never-smokers), and higher mortality (42.7 % vs. 31.8 % for never smokers). In the multivariable analysis, smokers demonstrated a heightened risk of death (aOR 1.23; 95 % CI 1.19-1.25). CONCLUSIONS: This large populational-based cohort study confirms the current evidence and underscore the critical importance of recognizing smoking as a substantial risk factor for adverse outcomes in COVID-19 patients.

Vaccination against COVID-19: the view of Brazilian federal judges.

The aim was to analyze the perception of Brazilian federal judges on the implications of COVID-19 vaccination. A study was carried out with Brazilian federal judges, who received a survey designed with multiple-choice questions on COVID-19 vaccination, covering topics such as its mandatory aspect, the application of coercive measures, hesitation to vaccinate, priority groups, the duties of Brazilian Health Regulatory Agency (Anvisa, acronym in Portuguese), the role of the Judiciary branch, and immunity passports. A total of 254 out of 1,300 federal judges from all states responded to the survey. Most respondents have a Bachelor's degree or a specialization (59.1%) and have been judges for more than 10 years (63.8%). A great majority of the judges (87.7%) agree with vaccine mandates for adults and for children and adolescents (66.1%). Over 75% of judges believe that all levels of government can impose sanctions on those who refuse to get vaccinated. The judges trust vaccination 93% of the time, 56.1% reject anti-vaccination movements, and 75.2% believe that Anvisa duties should be respected. The Judiciary branch actions concerning the COVID-19 pandemic are approved by 62.6% of judges, and 88.2% support immunity passports. There is a direct connection among mandatory vaccination, trust in the vaccine, and the adoption of immunity passports. Most federal judges agree with vaccine mandates for children and adults, support the application of sanctions for vaccination refusal, disapprove of anti-vaccination movements, agree with Anvisa's duties, and support judicial intervention in relation to the COVID-19 pandemic.

Evaluation of remote teaching in master programs in the Oral Pathology and Oral Medicine during the COVID-19 pandemic. Brazilian multicentric study

Background: With the COVID-19 pandemic, there was a need to adopt online teaching methods in a generalized and sudden way, a situation that led to unprecedented changes in the routine of post-graduate students and research development. This study aimed to analyze the evaluation of remote teaching by graduates of master's degrees and advisors in master's programs in the Oral Pathology and Oral Medicine who needed to adapt to a remote teaching methodology in the pandemic. Material and Methods: This quantitative study evaluated the remote teaching in the perception of master's graduates and advisors from postgraduate programs in Oral Pathology and Oral Medicine. Data were collected through an online Google forms® questionnaire. Results: Participated in the study 14 master graduates and 14 master's advisors. Master graduates evaluated that the professors had a good performance (p=0.001), that the duration of the classes was adequate (p=0.015), that the interaction with professors was satisfactory (p=0.007), that they had good interaction with the advisor (p=0.001), that they were satisfied with the remote guidance process (p=0.038) and that face-to-face practical activities were missed (p=0.002). Master's advisors reported satisfaction with remote teaching, good adaptation (p=0.018) and motivation for remote teaching (p=0.016), they evaluated that students were cooperative in activities (p=0.019) and that face-to-face practical activities were missed (p=0.002). Conclusions: Despite the difficulties, remote teaching proved to be an effective alternative to face-to-face teaching. (AU)

Maternal consumption of caffeine and second-hand tobacco smoke as risk factors for the development of oral clefts.

OBJECTIVE: The aim of this case-control study was to investigate environmental factors, such as caffeine, folic acid, nutritional iron supplementation, multivitamin complexes, alcohol, and tobacco (second-hand smoking), which have been described as risk factors for the development of oral clefts. METHODS: This case-control study employed convenience sampling and included 409 mothers: 132 with children with oral clefts (cases) and 277 with children without oral clefts (controls). The age range of the children in both groups was 0 to 2 years. A questionnaire was administered to each mother to inquire about their habits and food consumption during the first trimester of pregnancy. RESULTS: Folic acid supplementation was observed in 116 (87.8%) of the case group (p < 0.001) and 271 (97.8%) of the control group. Regarding the use of ferrous sulfate, 114 (86.3%) of the case group and 271 (97.8%) of the control group reported using it. In the case group, 84 (63.6%) mothers reported being exposed to second-hand smoke, and 5 (3.7%) reported alcohol consumption (p = 0.797). In terms of caffeine consumption, 127 mothers (95.4%) in the case group consumed it (p = 0.13), while 247 (88.8%) reported consumption in the control group. CONCLUSIONS: The results suggest a direct relationship between secondhand smoke, alcohol consumption, and the lack of maternal supplementation with oral clefts.

Specialized Dental Care in the Brazilian Unified National Health System (SUS)

ABSTRACT Objective: To analyze specialized dental care through access, demand and the work processes provided by the CEO's, using secondary data from the cycles of the PMAQ-CEO. Material and Methods: Cross-sectional study using public domain data. Variables of interest were selected from the external evaluation instrument data matrices and were grouped in categories. The categories were geographic distribution, structural, human resources, work processes and access and coordination. Results: The total of 932 CEO's were evaluated in 2014 and 1,042 in 2016, most of them type II, present in the Northeast region. In both cycles, the highest average of dentists worked in the endodontic specialty (2.4 professionals per CEO) and the lowest in oral medicine (0.8 professionals per CEO). Of the two cycles, 91.5% of the CEO's had a manager, 79.5% performed action planning activities and 74.5% realized internal self-assessment processes. There was an increase in the mean number of days to be seen at the CEO in all analyzed specialties (p<0.001) and 85.2% of the CEO's managers reported that there is a reference for oral cancer confirmed cases. Conclusion: Between the PMAQCEO cycles the number of CEO has increased, but there are still a big pent-up demand and the presence of care gaps. However, an expansion and improvement of the CEO's actions was evidenced, mainly related to the work processes.

Methods: This is a systematic review conducted based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. The databases used were the Biblioteca Virtual de Saúde (BVS) and the services of the United States National Library of Medicine (NLM) via PubMed, with the search strategies: "COVID-19" AND "Mental health"; "COVID-19" AND "Mental health" AND "health personnel", in Portuguese and English, selecting observational and/or prevalence articles published from 2020 onwards. Results: The search resulted in the identification of 18,643 articles, and the final sample consisted of 9 articles. The most frequently evaluated symptoms were symptoms of depression, anxiety and insomnia in professionals who worked during the COVID-19 pandemic period, predominantly female and mean age of 34.5 years. The average prevalence of anxiety, depression and insomnia was respectively 40.3%, 39.9% and 36.1%, measured in 8,866 health professionals. Health professionals working on the front line in the fight against Covid-19 had higher prevalence of common mental disorders in relation to other health professionals. Conclusions: The following were associated with a higher prevalence of CMD symptoms: female sex, frontline work, longer working hours, history of psychotropic medication use, inadequate working conditions, use of alcohol and tobacco, and work in the nursing field. The importance of mental health care strategies for health professionals is observed.
