Eosinopenia as Predictor of Poor Outcome in Hospitalized COVID-19 Adult Patients from Waves 1 and 2 of 2020 Pandemic.

During SARS-CoV-2 infection, eosinopenia may reflect a hyperactive immune response. In this study of hospitalized COVID-19 patients, we aimed to better understand the prognostic value of severe eosinopenia (absolute eosinophil count = 0 G/L) and decipher its underlying mechanisms. We retrospectively analyzed the records of COVID-19 patients hospitalized from March to June 2020 in three university hospitals in Marseille, France.

Factors associated with dexamethasone efficacy in COVID-19. A retrospective investigative cohort study.

Dexamethasone has demonstrated efficacy in reducing mortality in COVID-19. However, its practical use is badly defined. We aimed to investigate factors associated with dexamethasone efficacy in real life.

Coverage, determinants of use and repurposing of long-lasting insecticidal nets two years after a mass distribution in Lihir Islands, Papua New Guinea: a cross-sectional study.

Background: Universal coverage with long-lasting insecticidal nets (LLINs) is an essential component of malaria control programmes. Three-yearly mass distribution of LLINs in Papua New Guinea (PNG) has been successful in reducing infection transmission since 2009, but malaria prevalence ramped up from 2015 onwards. Although LLIN universal coverage is mostly achieved during these campaigns, it may not be related with net use over time.

[Socio-demographic and occupational factors associated with gains and losses perceived by employees nearing retirement in a public university].

The aim was to analyze socio-demographic and occupational factors associated with gains and losses perceived by employees nearing retirement in a public university. In an exploratory, cross-sectional, and quantitative survey, employees (n = 164) approaching retirement in a public university in northern Paraná State, Brazil, assigned scales of importance to gains and losses. The data were analyzed with simple and multiple linear regression, based on the sizes of the scales, with socio-demographic and occupational variables as predictors.

[Determining factors for neonatal mortality in a city in the southern region of Brazil].

This is an ecological quantitative study to identify risk factors that determined neonatal death between the years of 2000 to 2009 in Londrina, Paraná, using data from Birth Certificates, Death Certificates and Infant Death Investigation Forms. The variables maternal age, years of education, family income, occupation, marital status, type of delivery, and number of prenatal appointments were not associated to neonatal death. To the contrary, birth weight, gestational age, Apgar score at 1 and 5 minutes, and place of birth were identified as statistically significant variables.

Cross-sectional descriptive study aimed to assess the health status of nursing staff retrained due to illness of a public university hospital in northern Paraná, Brazil. Data of 34 workers were collected through the application of the Medical Outcomes Studies 36 items - Short Form (MOS SF-36). The results showed that physical problems were the reason for retraining in 91.

Objective: To verify the caloric and sanitary profile of human milk stored at the Human Milk Bank at Londrina University Hospital.

Methods: Cross-sectional study. Data were obtained from the Human Milk Bank registry regarding the source, the amount collected in liters, the amount of calories by liter assessed by crematocrit, and the acidity of human milk determined by titration in degrees Dornic.

Bone metabolism biomarkers, body weight, and bone age in healthy Brazilian male adolescents.

Eighty-seven male volunteers were grouped according to bone age (BA): 10-12 years (n=25), 13-15 years (n=36), and 16-18 years (n=26), and the following were recorded for each: weight (kg), height (m), BMI (kg/m(2)), calcium intake from three 24-h food recalls (mg/day), puberty evaluation by Tanner stages, bone biomarker (BB) evaluation, serum osteocalcin (OC), bone alkaline phosphatase (BAP), carboxyterminal telopeptide (S-CTx), and bone mineral density (BMD) evaluations by dual-energy X-ray absorptiometry (g x cm(2)) in the lumbar spine, proximal femur, and the whole body. BBs showed similar behaviors, and very high median values were observed for individuals aged 13-15 years (BAP = 155.50 IU/L, OC = 41.

Bone turnover is affected by exercise throughout the lifespan, especially during childhood and adolescence. The objective of this study was to investigate the impact of different sports on total and regional bone mineral density in male Brazilian adolescent athletes. Forty-six adolescents aged 10-18 years participated in the study: 12 swimmers, 10 tennis players, 10 soccer players, and 14 sedentary individuals.

Calcium intake and its relationship with risk of overweight and obesity in adolescents.

Adolescents' eating habits are determined by social, psychological, economic, political, and educational influences. They tend to prefer foods with inadequate nutritional value and high fat and carbohydrate content which leads to excessive weight gain and for many, calcium intake is restricted. According to some authors, low calcium intake is linked to increased adiposity.

Quality assessment of the wound dressing procedure in patients at a university hospital.

This observational and sectional study analyzed the quality of the wound dressing procedure performed on hospitalized patients at a medical surgical unit of a University Hospital, based on their classification according to the degree of care dependency and activity performance phases. Using a check list, 168 wound dressings were observed between October and December 2005. Procedure quality was analyzed based on the Positivity Index (IP) and values >70% were considered satisfactory.

Bone mineralization in Brazilian adolescents: the years of maximum bone mass incorporation.

Puberty is the fundamental period for bone mass (BM) acquisition. In this period mineralization is found to increase with levels of high bone formation. The critical years of intense bone anabolism deserve special attention, as adequate gain could minimize fracture risk in later years.

[A predictive analysis from bone mineral density among eutrophic Brazilian male adolescents].

Osteoporosis is considered one of the most serious public health diseases and studies show that it is a pediatric disease that manifests during senility. It is usually diagnosed in clinical practice by dual-energy x-ray absorptiometry (DXA). This exam has a high cost and it is difficult to apply to a pediatric population because specific equipment and special software are required.
