title: Influenza A (H1N1): outbreak management in a dialysis unit and clinical outcomes of infection in chronic hemodialysis patients

description: ABSTRACT Introduction: Chronic hemodialysis (HD) patients are considered to be at high risk for infection. Here, we describe the clinical outcomes of chronic HD patients with influenza A (H1N1) infection and the strategies adopted to control an outbreak of influenza A in a dialysis unit. Methods: Among a total of 62 chronic HD patients, H1N1 infection was identified in 12 (19.4%). Of the 32 staff members, four (12.5%) were found to be infected with the H1N1 virus. Outcomes included symptoms at presentation, comorbidities, occurrence of hypoxemia, hospital admission, and clinical evaluation. Infection was confirmed by real-time reverse transcriptase polymerase chain reaction. Results: The 12 patients who had H1N1 infection did not differ significantly from the other 50 non-infected patients with respect to age, sex, dialysis vintage, dialysis modality, or proportion of comorbidities. Obesity was higher in the H1N1-infected group (41.5 vs. 4%, p&lt;0.002). The most common symptoms were fever (92%), cough (92%), and rhinorrhea (83%). Early empirical antiviral treatment with oseltamivir was started in symptomatic patients and infection control measures, including the intensification of contact-reduction measures by the staff members, antiviral chemoprophylaxis to asymptomatic patients undergoing HD in the same shift of infected patients, and dismiss of staff members suspected of being infected, were implemented to control the spread of infection in the dialysis unit. Conclusion: The clinical course of infection with H1N1 in our patients was favorable. None of the patients developed severe disease and the strategies adopted to control the outbreak were successful.

title: Associations between psychosocial risk factors, organizational dimensions, and mental health problems related to workplace violence among workers of three Chilean hospitals of high complexity

description: Abstract: The objective was to analyze the association between psychosocial risk factors, organizational dimensions, workplace violence, and indicators of mental health problems in three Chilean hospitals. A total of 1,023 workers answered a questionnaire, and descriptive, bivariate (chi-square), and multivariate (logistic regression with odds ratio as the measure of association) analyses were performed. Of all the interviewees, 14.7% reported workplace violence. Increased odds of workplace violence were associated with exposure to ISOSTRAIN (OR = 2.32, p = 0.001), effort-reward imbalance (OR = 5.52, p ≤ 0.001), tyrannical leadership (OR = 3.02, p ≤ 0.001), and vulnerability (OR = 1.97, p = 0.010). Workers exposed to ISOSTRAIN (OR = 1.78, p = 0.024), effort-reward imbalance (OR = 2.49, p = 0.001), workplace violence (OR = 2.13, p = 0.003), and vulnerability (OR = 2.29, p = 0.001) showed increased odds of high stress when compared to unexposed workers. Workers exposed to effort-reward imbalance (OR = 2.84, p ≤ 0.001) and workplace violence (OR = 1.76, p = 0.041) showed higher odds of reporting depressive symptoms. Those exposed to effort-reward imbalance (OR = 2.07, p ≤ 0.001) and work vulnerability (OR = 1.96, p = 0.001) showed higher odds of consuming psychoactive drugs. Work contexts with psychosocial risk factors, adverse organizational dimensions, and work vulnerability were associated with higher odds of workplace violence. Workers exposed to workplace violence, psychosocial risks, and vulnerability have higher odds of reporting mental health problems.

title: EVALUATION OF MANGROVE AND ITS ROLE IN THE ECONOMY AND STRATEGY TO CLIMATE CHANGE: CASE STUDY OF CUIARANA, PARÁ, IN THE BRAZILIAN AMAZON

description: ABSTRACT This research aimed to estimate the seasonal economic value of ecosystem goods and services from research on the use of mangroves in the Cuiarana community in the Eastern Amazon. The methodology of Total Economic Value was used, through interviews with 15 residents who extract products from the mangrove. For the ecosystem services, atmospheric carbon (measured by a micrometeorological tower), and organic carbon (monitored by soil sampling during 2017) were used. In determining product values, the quantities extracted at market prices and the value of services were estimated using carbon credits. The results indicate that the ecosystem produces 9 community assets, that generate R$ 75,033.50 (US$ 23,622.93 ha/year) and R$ 17,627.15 (US$ 5,549.58 ha/year) for capture and storage respectively. The VET value corresponded to R$ 986,132.50 (US$ 310,465.79). Ecosystem services and the economic values of atmospheric (p = 0.0278) and soil carbon credit (p = 0.0354) indicated higher importance in the rainy season due to the precipitation that favored an increase in the amount of carbon. This behavior was verified by the Principal Components Analysis (50.1%), which showed that in the less rainy season goods are more important when compared to the ecosystem services.

title: Factors associated with sleep disorders in university students

description: The objective was to investigate sleep disorders and associated sociodemographic and behavioral factors. A census of university students was carried out. Questions extracted from the Munich Chronotype Questionnaire investigated: insufficient sleep duration (&lt; 6 hours/day for &lt; 65 years and &lt; 5 hours/day for other ages), long latency (&gt; 30 minutes), low self-rated sleep quality, nocturnal awakenings (involuntary, in the middle of the night), and daytime sleepiness (difficulty concentrating). Independent variables included sociodemographic and behavioral characteristics. Adjusted analyses were performed with Poisson regression. Of the 1,865 students, 32% exhibited insufficient sleep on class days, 8.2% insufficient sleep on weekends, 18.6% long latency on class days, 17.2% long latency on weekends, 30% low self-rated sleep quality, 12.7% nocturnal awakenings, and 32.2% daytime sleepiness. Higher alcohol consumption was associated with insufficient sleep duration and long latency on class days, low quality sleep, awakenings, and daytime sleepiness. Smoking was associated with insufficient sleep duration on weekends, awakenings, and low-quality sleep. Black and brown skin color were associated with insufficient sleep duration on class days, low-quality sleep, and awakenings. Morning classes were associated with insufficient sleep and daytime sleepiness. Female gender was associated with low-quality sleep and awakenings. The most frequent sleep disorders were insufficient sleep on class days, low self-rated quality of sleep, and daytime sleepiness. Alcohol consumption and smoking and black and brown skin color were the principal factors associated with sleep disorders.

title: Cardiometabolic diseases and active aging - polypharmacy in control

description: ABSTRACT Objectives: To estimate the prevalence of cardiometabolic diseases and their association with polypharmacy in elderly people at the University of the Third Age (Portuguese acronym: UnATI). Methods: A cross-sectional, descriptive, analytical study with 121 elderly patients. The prevalence ratio, Pearson’s Chi-square test and Fisher’s exact test were used as measures of association. Results: At the mean age of 68.3, most elderly had at least one cardiometabolic disease (82.6%), of which hypertension was the most prevalent (71.1%), and consumed prescription drugs of continuous use (92.6%). Almost half of the elderly (48.2%) used combinations of drugs, which suggests a high cardiovascular risk. Polypharmacy due to prescription was observed in almost one-third (28.6%) of the sample, associated with the use of antihypertensives (p=0.004), antidiabetics (p=0.000) or lipid-lowering agents (p&lt;0.000). Conclusions: Clinical guidelines recommend changes in lifestyle, but increased pharmacotherapy prevails in practice, which increases the risk of adverse events, especially in old age.

title: Correlation Among the Input Thermal Parameters and Thermography Measurements Data of the Resistance Seam Welding

description: Abstract Resistance Seam Welding (RSEW) is commonly used in continuous steel processing for joining steel coils. Experimental studies focused on the welding process quality controls are justified by their wide application and influence on the performance of steelmaking processes. The present study focuses on the continuous annealing line welding process using as sample, a low carbon steel (0.07%C) with 0.21 mm thickness. The work proposes a correlation of thermal input, electric current parameter and thermogram monitoring during RSEW procedures. A methodology was developed to determine the real thermal profiles values by means of association of the thermograms with the sample emissivity curve. Three heat input levels were used, 3.64 J.mm-1, 5.09 J.mm-1, and 6.38 J.mm-1, respectively, for typical C-Mn steel. The thermal welding profile obtained experimentally exhibited linear correlation coefficients (R) of 0.99 with the electric current welding parameter and (R) of 0.99 with the calculated thermal input, respectively. The welds metallurgical characterizations results, expressed through the ductility and welds nuggets analysis, were conducted to correlate the welds quality with the welding thermal input. The Erichsen cupping test showed that the higher the thermal input corresponds to higher ductility of the welds. Nevertheless, the heat input of 5.09 J.mm-1 indicated better-balanced properties: ductility, weld nugget discontinuity, nugget size, and no expulsion of the melt material.

title: Physical and Photocatalytic Properties of CeO2/ZnO/ZnAl2O4 Ternary Nanocomposite Prepared by Co-precipitation Method

description: Abstract ZnAl2O4 spinel nanoparticles and CeO2/ZnO/ZnAl2O4 ternary nanocomposites were synthesized by a co-precipitation method. The structural, morphological, optical properties and chemical compositions of the products were analyzed respectively by X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS) and X-ray fluorescence (XRF) spectroscopy. The optical band gap of ZnAl2O4 spinel nanoparticles was 3.220 eV. When 1.0 mmol Ce(NO3)3•6H2O was added to the synthesis reaction, the optical band gap of the obtained ternary nanocomposite was 3.170 eV. The influence of phase composition, optical band gap, oxygen vacancy and specific surface area on photocatalytic activity over CeO2/ZnO/ZnAl2O4 ternary nanocomposites was investigated. The CeO2/ZnO/ZnAl2O4 nanocomposite prepared with 1.0 mmol Ce(NO3)3•6H2O showed the lowest recombination rate of photoexcited electron-hole pairs, the narrowest optical band gap (3.170 eV) and the highest oxygen vacancy concentration or highest Urbatch energy (0.299 eV). These parameters produced the best photocatalytic activity toward methylene blue (MB) under UV irradiation. The CeO2/ZnO/ZnAl2O4 ternary nanocomposites exhibited better photocatalytic performance than pure ZnAl2O4 spinel nanoparticles and 100% degradation of aqueous MB solution was achieved within 60 min when using the CeO2/ZnO/ZnAl2O4 ternary nanocomposite photocatalyst synthesized with 1.0 mmol Ce(NO3)3•6H2O.

title: Drivers of floristic variation in biogeographic transitions: insights from the ecotone between the largest biogeographic domains of South America

description: ABSTRACT Ecological transitions usually represent vulnerable ecosystems and high biodiversity. Investigating their drivers is important from both biogeographic and conservationist perspectives. One of these transitions is situated between the two largest biogeographic domains of South America - the Amazon and the Cerrado. We evaluated variation in tree floristic composition throughout this transition and assessed which factors explain this variation. We used 17,240 records of occurrences of 2,530 tree species from the NeotropTree database. We investigated variation in floristic composition using UPGMA cluster analysis with bootstrap resampling and NMDS ordination, and modeled the distribution of species in relation to environmental and spatial predictors by means of transformation-based Redundancy Canonical Analysis (tb-RDA) and variance partitioning. We found four general floristic groups: 1) flooded forests; 2) white sand dwarf-forests; 3) savannic and dwarf forests; and 4) non-flooded forest types. Floristic variation along the transition was influenced by the environment, especially variables related to fire and soil moisture, and by space, especially variables acting on broader scales. Correspondence between the environmental heterogeneity found throughout the transition and our results demonstrates once again the importance of conserving biogeographical transition zones in general, and the most comprehensive of South America in particular.
