It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke, and other geriatric syndromes such as immobility and cognitive disability.

This study aimed to analyse the survival of patients admitted to Brazilian hospitals due to the COVID-19 and estimate prognostic factors. This is a retrospective, multicentre cohort study, based on data from 46 285 hospitalisations for COVID-19 in Brazil. Survival functions were calculated using the Kaplan–Meier's method. The log-rank test compared the survival functions for each variable and from that, hazard ratios (HRs) were calculated, and the proportional hazard model was used in Cox multiple regression. The smallest survival curves were the ones for patients at the age of 68 years or more, black/mixed race, illiterate, living in the countryside, dyspnoea, respiratory distress, influenza-like outbreak, O2 saturation <95%, X-ray change, length of stay in the intensive care unit (ICU), invasive ventilatory support, previous heart disease, pneumopathy, diabetes, Down's syndrome, neurological disease and kidney disease. Better survival was observed in the influenza-like outbreak and in an asthmatic patient. The multiple model for increased risk of death when they were admitted to the ICU HR 1.28, diabetes HR 1.17, neurological disease HR 1.34, kidney disease HR 1.11, heart disease HR 1.14, black or mixed race of HR 1.50, asthma HR 0.71 and pneumopathy HR 1.12. This reinforces the importance of socio-demographic and clinical factors as a prognosis for death.

BackgroundObese people have abnormal deposition of fat in the vocal tract that can interfere with the acoustic voice.AimTo relate the fundamental frequency, the maximum phonation time and voice complaints from a group of morbidly obese women.MethodsObservational, cross-sectional and descriptive study that included 44 morbidly obese women, mean age of 42.45 (±10.31) years old, observational group and 30 women without obesity, control group, with 33.79 (±4.51)years old. The voice recording was done in a quiet environment, on a laptop using the program ANAGRAF acoustic analysis of speech sounds. To extract the values ​​of fundamental frequency the subjects were asked to produce vowel [a] at usual intensity for a period in average of three seconds. After the voice recording, participants were prompted to produce sustained vowel [ a] , [ i] and [ u] at usual intensity and height, using a stopwatch to measure the time that each participant could hold each vowel.ResultsThe majority, 31(70.5%), had vocal complaints, with a higher percentage for complaints of vocal fatigue 20(64.51%) and voice failures 19(61.29%) followed by dryness of the throat in 15 (48.38%) and effort to speak 13(41.93%). There was no statistically significant difference regarding the mean fundamental frequency of the voice in both groups, but there was significance between the two groups regarding maximum phonation.ConclusionIncreased adipose tissue in the vocal tract interfered in the vocal parameters.

Congenital syphilis (CS) remains a threat to public health worldwide, especially in developing countries. To mitigate the impacts of the CS epidemic, the Brazilian government has developed a national intervention project called “Syphilis No.” Thus, among its range of actions is the production of thousands of writings featuring the experiences of research and intervention supporters (RIS) of the project, called field researchers. In addition, this large volume of base data was subjected to analysis through data mining, which may contribute to better strategies for combating syphilis. Natural language processing is a form of knowledge extraction. First, the database extracted from the “LUES Platform” with 4,874 documents between 2018 and 2020 was employed. This was followed by text preprocessing, selecting texts referring to the field researchers' reports for analysis. Finally, for analyzing the documents, N-grams extraction (N = 2,3,4) was performed. The combination of the TF-IDF metric with the BoW algorithm was applied to assess terms' importance and frequency and text clustering. In total, 1019 field activity reports were mined. Word extraction from the text mining method set out the following guiding axioms from the bigrams: “confronting syphilis in primary health care;” “investigation committee for congenital syphilis in the territory;” “municipal plan for monitoring and investigating syphilis cases through health surveillance;” “women's healthcare networks for syphilis in pregnant;” “diagnosis and treatment with a focus on rapid testing.” Text mining may serve public health research subjects when used in parallel with the conventional content analysis method. The computational method extracted intervention activities from field researchers, also providing inferences on how the strategies of the “Syphilis No” Project influenced the decrease in congenital syphilis cases in the territory.

The epidemic caused by COVID-19 in Brazil is associated with an unfavorable political scenario, aggravated by intense social inequality and low number of available hospital beds. Therefore, this study aimed to analyze the survival of patients admitted to Brazilian hospitals due to the COVID-19 and estimate prognostic factors. This is a retrospective, multicenter cohort study, based on data from 46285 hospitalizations for COVID-19 in Brazil. Survival functions were calculated using the Kaplan-Meier method. The Log-rank test compared the survival functions for each variable and from that, hazard ratios were calculated and the proportional hazards model was used in Cox multiple regression. The smallest survival curves were the ones for patients at the age of 68 years or more, black / brown race, illiterate, living in the countryside, dyspnea, respiratory distress, influenza-like outbreak, O2 saturation <95%, X-ray change, length of stay in the ICU, invasive ventilatory support, previous heart disease, pneumopathy, diabetes, down's syndrome, neurological disease and kidney disease. Better survival was observed in the symptoms and in an asthmatic patient. The multiple model for increased risk of death when they were admitted to the ICU HR 1.28 (95% CI 1.21;1.35), diabetes HR 1.17 (95% CI 1.11;1.24), neurological disease HR 1.34 (95% CI 1.22;1.46), kidney disease HR 1.11 (95% CI 1.02;1.21), heart disease HR 1.14 (95% CI 1.08;1.20), black or brown race of HR 1.50 (95% CI 1.43;1.58), asthma HR 0.71 (95% CI 0.61;0.81) and pneumopathy HR 1.12 (95% CI 1.02;1.23). The overall survival time was low in hospitalizations for COVID-19 and this reinforces the importance of sociodemographic and clinical factors as a prognosis for death. The lack of a protocol for scientific clinical management puts a greater risk of death for about 80 million Brazilians, who are chronically ill or living in poverty. COVID-19 can promote selective mortality that borders the eugenics of specific social segments in Brazil.

Importância da calagem, adubações tradicionais e alternativas na produção de plantas forrageiras: Revisão

RESUMOO presente trabalho tem como objetivo avaliar, em obra, a resistência superficial à tração (RST) de revestimentos de argamassa. O ensaio para avaliação dessa propriedade ainda não é normalizado no Brasil, merecendo, portanto, estudos visando a sua futura padronização, haja vista ser a resistência superficial de um revestimento de argamassa um dos aspectos relevantes no que tange ao seu desempenho. Neste sentido, foram realizadas avaliações em duas obras de diferentes construtoras na cidade de Goiânia (estado de Goiás, Brasil), onde foram analisadas a influência do operador do ensaio, as influências do traço, local de aplicação e idade do revestimento, e a influência da ergonomia durante a produção do revestimento. Os resultados obtidos foram analisados empregando procedimentos estatísticos, tendo sido calculado o tamanho da amostra e realizadas análises de variâncias, além de correlações entre a RST e outros ensaios realizados. Como resultado, obteve-se que o tamanho da amostra compatível com a variabilidade obtida no ensaio é de 10 a 15 corpos-de-prova por situação individual de análise. Também se verificou que as variáveis estudadas (traço da argamassa, idade do revestimento e ação de intempéries) exercem influência significativa nos resultados de RST. Foram observadas correlações satisfatórias entre a RST e os resultados de ensaios de resistência de aderência (r=0,87), permeabilidade (r=0,81) e índice esclerométrico (r=0,99).

Objective: Analyzing the survival of older people hospitalized due to COVID-19 in Brazil and identifying its main predictive factors for death. Method: This is a retrospective, multicenter cohort study, based on 20,831 records of hospitalizations of older people due to SARS-CoV-2 in Brazil. The observation period was from February 28 to May 18, 2020. Results: There was a reduced overall survival time of 47.70% (95% confidence interval [CI] = [46.72%, 48.67%]) in 10 days. The variables age, race, education, intensive care unit (ICU), region, day of hospitalization, time elapsed between the first symptom and hospitalization, and the municipality that provided assistance showed increased risk of death using the multiple Cox proportional-hazards model. Conclusion: These results emphasize the relevance of inequality and access to health services as determinants for the death of older people with COVID-19.
