Prevalence and factors associated with wound colonization by Staphylococcus spp. and Staphylococcus aureusin hospitalized patients in inland northeastern Brazil: a cross-sectional study

Background: Hyponatremia is associated with unfavorable outcomes in many cases. The mainstay of hyponatremia treatment depends on its symptoms and etiology. However, etiologies, clinical manifestations, and factors associated with severe symptomatic hyponatremia have been rarely reported. Objective: To analyze and report etiologies, clinical manifestations, and factors associated with severe symptomatic hyponatremia. Materials and Methods: In the present cross-sectional study, the authors enrolled hospitalized patients with hyponatremia who had consulted a nephrologist between October 1, 2017, and October 31, 2018. Their baseline characteristics and clinical manifestations were recorded. Etiologies were confirmed by the attending nephrology staff. Factors associated with severe symptomatic hyponatremia were evaluated using logistic regression analysis. Results: One hundred patients were included in this study. The syndrome of inappropriate antidiuresis (SIAD), hypovolemia, and hydrochlorothiazide use were the leading hyponatremia etiologies. Hyponatremia etiologies differed between patients with community-acquired hyponatremia (n=50) and those with hospital-associated hyponatremia (n=50). Patients with communityacquired hyponatremia were older, presented with a higher frequency of severe symptomatic hyponatremia, and showed lower SNa-levels. Low SNa-levels were significantly associated with severe symptomatic hyponatremia (p=0.014). Conclusion: Hyponatremia remains an important health problem. SIAD, hypovolemia, and hydrochlorothiazide use are among the leading etiologies of hyponatremia. Low SNa-levels are associated with severe symptomatic hyponatremia; thus, physicians should pay close attention to low SNa-levels in hospitalized patients.

CONTEXT: Blood transfusion is one of the major risk factors for the transmission of the hepatitis B (HBV) and C (HCV) viruses. However, there are no reports describing the endoscopic transmission of these viruses in patients with the hepatosplenic form of schistosomiasis. OBJECTIVE: To estimate the prevalence of serological markers of HBV and HCV in patients with the hepatosplenic form of schistosomiasis and evaluate the possible risk factors associated with these infections. METHODS: A cross-sectional study was conducted on 230 patients with hepatosplenic form of schistosomiasis who attended a university hospital in Recife, Northeastern Brazil, from February to August 2008. The patients answered a standardized questionnaire about risk factors. Serum samples were analyzed for anti-HBc total, anti-HBs, HBsAg, and anti-HCV using enzyme-linked immunosorbent assays. Univariate analysis and multiple logistic regression were performed. RESULTS: The prevalence was 30% for anti-HBc total and/or HBsAg and 7.4% for anti-HCV. There was a higher frequency of the serological markers in females and in patients aged .50 years. A significant association was detected between the presence of anti-HCV and the receipt of six or more blood transfusions. There was no association of history and number of digestive endoscopies with the serological markers analyzed. CONCLUSIONS: We observed a higher prevalence of serological markers for HBV and a lower prevalence of anti-HCV. Our results indicate that females and patients of an advanced age are the most affected categories and that patients that received multiple transfusions are at a higher probability of HCV infection.

Abstract Background: Globally, childhood immunization saves the lives of 2-3 million children annually by protecting them against vaccine-preventable diseases. In 2017, 116.2 million children were vaccinated worldwide according to the World Health Organization. Nevertheless, figures suggest that 19.5 million children around the world fail to receive the benefits of complete immunization.Methods: This cross-sectional study analyzed vaccine uptake and the factors associated with incomplete vaccination schedule in children of up to 36 months of age assisted by the family health strategy in an irregular settlement located in a state capital city in northeastern Brazil. This study was nested within a larger study entitled “Health, nutrition and healthcare services in an urban slum population in Recife, Pernambuco”, conducted in 2015. A census included 309 children, with vaccination data obtained, exclusively, from their vaccination cards records. An ad hoc database was constructed with variables of interest. Absolute and relative values were calculated for the socioeconomic, demographic, obstetric and biological data. To identify possible factors associated with incomplete vaccination schedule, crude and multivariable Poisson regression analyses were performed, and conducted in accordance with the forward selection method with robust variance and the adjusted prevalence ratio was calculated with the 95% CI. Variables with p-values <0.20 in the unadjusted stage were included in the multivariable analysis. The statistical significance of each variable was evaluated using the Wald test, with p-values <0.05. Results: Just half of the children (52,1%) was classified as complete vaccination schedule. In the final model, the factors associated with incomplete vaccination schedule were age 12-36 months and the mother who did not complete high school.Conclusion: The percentage of vaccine uptake found was far below the recommendation of the National Childhood Immunization Schedule and was associated with child’s age and mother’s education level. Based on these findings, the family healthcare teams may elaborate vaccination strategies aimed at reaching the coverage rates established by the national immunization program. Optimizing coverage will ultimately prevent the resurgence, at epidemic level, of infectious diseases that are already under control in this country.

Background: Leprosy is a neglected, chronic and infectious tropical disease, caused by Mycobacterium leprae. It presents with skin and peripheral nerves alterations, responsible for irreversible physical disabilities. Brazil is one of the main countries endemic for the disease, persisting as a public health problem; its position is the first in the world in terms of prevalence coefficient. Objectives: To analyze the magnitude and factors associated with activity limitation in new leprosy cases diagnosed in the reference center in northeastern Brazil. Methods: This is a cross-sectional study, carried out in a reference center located in the municipality of Juazeiro - Bahia, between January and June 2018, involving 50 people diagnosed with leprosy. Clinical and sociodemographic variables were collected in addition to the application of the SALSA scale (Screening of Activity Limitation and Safety Awareness) for the analysis of functional limitation. The data were structured using Microsoft Excel software and, for analysis, IBM SPSS Statistics for Windows was used. Logistic regression was used with the calculation of the Odds Ratio to identify the factors associated with functional limitation. A 95% confidence interval and a 5% significance level were adopted. Results: The presence of functional limitations was registered in 32% (n = 16) of the cases analyzed, especially female (56.3%), elderly (37.5%), low education (87.6%), dimorphic form (62.5%), multibacillary classification (75.0%) and degree 2 of physical disability (50.0%). Functional limitation was associated with: age group ≥ 45 years (OR 3.80; p = 0.047), multibacillary age (OR 4.28; p = 0.021) and OMP score ≥ 6 (OR 4.69; p = 0.041). 75% of individuals with limitations were aged ≥ 45 years and were multibacillary. Conclusions: The factors associated with functional limitation were age equal to or greater than 45 years, multibacillary classification and OMP score greater than or equal to six. Early diagnosis and timely treatment in the routine of health services can contribute to the prevention of physical disability and functional limitations.
