title: Characteristics of long-term home oxygen therapy users in the municipality of Curitiba, Brazil

description: Abstract Introduction: Long-term home oxygen therapy (LTOT) can be successfully used in the treatment and prevention of chronic lung diseases, as it improves quality of life, increases survival, and reduces the lenght of hospital stays. However, to the authors’ knowledge there are no descriptive studies with details of the clinical and social profile of patients using LTOT in the state of Paraná. Objective: To analyze the profile of LTOT users in the state of Paraná. Method: All patients registered in the LTOT program of the Curitiba Municipal Department of Health were recruited to the study. Participants answered a questionnaire with questions about their education level, family income, main diagnosis, comorbidities, hours/day of O2 use, and hospitalizations in the previous year. Results: 386 patients (67 ± 20.4 years; 66% females) were interviewed. Chronic obstructive pulmonary disease (COPD) was the most common disease (58.5%); 60.6% were former smokers and 84.5% did not practice any kind of physical activity; dyspnea was the most common symptom (81.3%) and immobility was the most commonly reported inconvenience (33%); 55.7% used O2 24 hours a day; 53.6% had been hospitalized in the previous year; 33.9% had not completed primary school; 31.4% had an income of one minimum monthly wage or less. Conclusion: LTOT users in Curitiba are primarily elderly women with COPD, with low family income and limited schooling. It is extremely important that health professionals provide educational and preventive measures for this population, to minimize the impact of COPD in the community.

title: Organic minerals with different chemical characteristics in diets for Hy-Line White laying hens: performance, biometry of digestive organs, and bone quality

description: ABSTRACT Two trials were carried out to evaluate the effect of groups of organic minerals with different chemical characteristics on the performance, egg quality, biometry of digestive organs, and bone quality of laying hens in the first and second laying cycles. In the first cycle, 180 layers at 72 weeks were used in a completely randomized design (CRD) with four treatments and five replicates with nine birds each. In the second cycle, 216 layers at 94 weeks of age were used in a CRD with four treatments and six replicates with nine birds each. Birds were fed the following diets: treatment 1 - basal diet (inorganic minerals); treatment 2 - basal diet + amino acid chelated minerals (Cu, Fe, Mn, and Zn) + selenium yeast; treatment 3 - basal diet + mineral-amino acid complex (Mn, Zn, and Cu); and treatment 4 - basal diet + metal chelate (Mn, Zn, and Cu) + methionine hydroxy analogue. The following performance variables were evaluated: feed intake (g/bird/day), egg production (%), egg weight (g), egg mass (g/bird/day), conversion per mass (kg/kg), and conversion per dozen eggs (kg/dz). In the egg, the percentages of albumen, yolk, and shell; eggshell thickness (mm); and specific gravity (g/cm3) were determined. The relative weights (%) of the proventriculus, gizzard, liver, pancreas, and intestines were also measured. Lastly, in the tibiae, the weight (g), length (mm), resistance (kgf/cm2), deformity (mm), Seedor index (mg/mm), and mineral matter content (g/kg) were measured. The variables were not influenced by the groups of organic minerals used. Groups of organic minerals with different chemical characteristics can be used in layer diets without affecting their performance, egg quality, digestive organs, or bone quality.

title: Increased urinary losses in piglets fed diets containing high levels of glycerin

description: ABSTRACT This study evaluated the nutritional value of glycerin added to diets of weaned piglets and its effects on animal performance and urinary losses. Weaned piglets were individually housed in metabolic cages and fed diets in which a basal diet containing lactose (Gly0) was replaced by 50 (Gly50), 100 (Gly100), or 150 g kg−1 (Gly150) of glycerin; or a diet in which 100 g kg−1 of the lactose in the basal diet was replaced by glycerin (Gly100Lac0). Diets were offered for two periods of 12 days (phase I and phase II). Performance, nutrient digestibility, nitrogen retention (NR), and urinary production were measured. Digestible (DE) and metabolizable energy (ME) of glycerin were calculated using substitution method and compared to iso-nutritional diets formulated with or without glycerin. No significant differences on average daily gain, average daily feed intake, and feed conversion ratio were found. Glycerin inclusion caused a linear increase in urinary production. Piglets fed Gly100Lac0 diet had higher urinary production, compared with piglets fed Gly0. Glycerin had no significant effects on total tract apparent digestibility (TTAD) coefficients of dry matter (DM), crude protein, and gross energy (GE). Also, no significant effects were found in total tract apparent metabolizability (TTAM) coefficient of GE, NR coefficient, DE, ME, and fecal GE losses. Urinary production and GE in urine increased linearly and quadratically, respectively, with increased levels of glycerin in diets. The Gly100Lac0 diet resulted in lower DM TTAD and GE TTAM and higher GE losses in urine and feces compared with Gly0. The nutritional value of glycerin allows its inclusion at up to 100 g kg−1 in diets of weaned piglets without impairing animal performance and metabolism. Also, glycerin can replace 100 g kg−1 of lactose without impairing performance.

title: Internal mechanical work and maximum subtalar joint pronation in different gradients

description: Abstract Introduction: Some authors have described the importance of physiological intensity in the behavior of the biomechanical aspects of running (for example, subtalar pronation), but the complex relationships between these variables are not yet well understood. Objective: This study investigated the influence of positive gradients on internal mechanical work (Wint) and maximum subtalar pronation at a submaximal running speed. Method: Sixteen male, trained long-distance runners (age: 29 ± 7 yr; stature: 1.72 ± 0.07 m; body mass: 72.1 ± 10.6 kg), performed four running economy tests (gradients: +1%, +5%, +10% and +15%, respectively) for four minutes at a same submaximal running speed to quantify the maximum values of subtalar pronation and predict the Wint values. Data were analyzed using descriptive statistics, Student’s T-test, and one-way repeated-measures (ANOVA) along with the Statistical Package for the Social Sciences (SPSS) version 20.0. Results: Wint increased according to the gradient (p &lt; 0.05). However, no significant differences were observed in the maximum values of maximum subtalar pronation corresponding to each gradient. Conclusion: Results show the maximum subtalar pronation during submaximal running depends on the speed rather than intensity of effort.

title: Effects of a muscular stretching and strengthening school-based exercise program on posture, trunk mobility, and musculoskeletal pain among elementary schoolchildren - a randomized controlled trial

description: Abstract Introduction: The exercise benefits for the most prevalent postural changes require proper investigation, with large samples, control group, and concealed allocation. Objective: To assess the effects of a muscular stretching and strengthening school-based exercise program on posture, trunk mobility, and musculoskeletal pain among elementary schoolchildren. Method: Three hundred students from three schools in Brazil were evaluated. Stretching and strengthening exercises, twice a week, for eight weeks in group sessions were provided by one physiotherapist. The control group did not undergo any intervention. Head, back and shoulder posture were qualitatively evaluated. Head and trunk alignment were evaluated using the Posture Assessment Software. Cervical, thoracic, low back and upper limb pain were assessed for the last seven days. The trunk mobility was recorded through the flexibility of the posterior chain. Posture, pain and trunk mobility were recorded at baseline and after the intervention. Groups were compared using χ2 test, two-way MANOVA, and two-way ANOVA, with α set at 5%. Results: Shoulder posture showed significant results (P = 0.04), the intervention group showed the lower worsening rate. In the quantitative evaluation, a statistically significant difference was observed between assessments (P &lt; 0.01 for head and trunk; ES = 0.53) but not between groups. The intervention group had a higher percentage of improvement in the overall musculoskeletal pain (P = 0.04; ES = 0.54). Mobility decreased an average of 1.8° in the control group and increased 5.0° in the intervention group, without statistical significance. Conclusion: The program was effective in reducing pain level and shoulder misalignment at the intervention group.

title: SPATIAL AND SEASONAL EVALUATION OF CONCENTRATIONS OF TOTAL SUSPENDED PARTICLES AND ASSOCIATED METALLIC ELEMENTS IN THE AIR OF A SOUTHEASTERN BRAZILIAN CITY

description: The present study evaluated the concentrations of Total Suspended Particles (TSP) and associated metals in three distinct regions of Ribeirão Preto city (Center City, Campus and Airport) in the dry and rainy seasons. There were no significant differences (p &lt; 0.05) in TSP and metals concentrations between the sampling sites, except for Cu, Cr and Zn. Seasonal variation was observed for TSP and the following associated metals: As, Be, Cu, Mn, Ni, Pb, Sn and V, being the highest concentrations observed in the dry period. The TSP concentrations did not exceed the air quality standards in São Paulo state, but these can cause harm to the population health, especially in the dry season. Cadmium was the only element that exceeded the WHO air quality guidelines in two consecutive samplings in the Center City and the Airport during the dry season. In this way, preventive measures should be taken through public policies to improve local air quality control and reduce the health risks to the population.

title: QUALITY OF LIFE IN THE PRE- AND POSTOPERATIVE PERIODS IN SPINAL FUSION AND DISCECTOMY

description: ABSTRACT Objectives: Considering the epidemiological and functional importance of spinal pathologies and the large number of surgeries performed today, the study aimed to evaluate the impact of spinal arthrodesis and discectomy surgeries on patients’ quality of life. Methods: This is a retrospective, descriptive, and longitudinal study developed in the neurology and neurosurgery department of a strategic tertiary hospital in an inland town in the state of São Paulo. Data were collected through a telephone interview, using the Oswestry questionnaire (ODI) to assess lumbar pain in patients submitted to surgery in 2014 and 2015. Results: There was an improvement in the ODI results in all the periods analyzed. When the evaluations were subdivided by surgical type, there was an absolute improvement in the median ODI results in all procedures, however, only the cervical spine arthrodesis procedure was not statistically significant, probably due to the low number of procedures analyzed (n = 12). Conclusion: It can be concluded that the current surgical technique can contribute to the improvement of patients’ quality of life. Level of Evidence III; Comparative retrospective study.

title: Selective Solar Surface Solar Based on Black Chromium: Influence of Electrodeposition Parameters in the Absorption of Surfaces

description: The search for the reduction of costs for the implementation of renewable energies implies in the optimization of the parameters of the manufacturing processes of consolidated technologies. Among these technologies are the solar collectors composed of absorber films characterized by high absorption in the spectrum range corresponding to solar radiation and low emittance in the infrared range, allowing an increase in the collector's operating temperature (300 to 700°C). The present work produced selective surfaces based on black chrome absorber films on stainless steel substrate by electrodeposition. The substrates were immersed in a chromium trioxide bath with hexafluorosilicic acid using a Pb-Sn electrode. In the project some parameters of deposition were evaluated (time, distance and voltage) and their influence on the surface roughness of the coatings obtained by correlating them with the absorptions of the produced surfaces. For this, the surfaces produced were characterized by UV-Vis-NIR, profilometry and SEM. The results indicate that the working distance directly influenced the increase of the films absorption and that the influence of the surface roughness on the film absorption is related to the electrodeposition time as the voltage is raised.

title: CARDIOMETABOLIC RISK FACTORS ASSOCIATED WITH ACTIVE COMMUTING TO SCHOOL

description: ABSTRACT Objective: To verify if there is an association between cardiometabolic risk factors and active daily commuting to school among children and adolescents. Methods: A total of 1,743 schoolchildren aged 7 to 17 years old were evaluated in the city of Santa Cruz do Sul (RS). The way of commuting to school was investigated with a questionnaire, and the cardiometabolic risk factors analyzed were body mass index (BMI), waist circumference (WC), systolic (SBP) and diastolic (DBP) blood pressure, blood glucose, triglycerides, total cholesterol (TC) and fractions, LDL and HDL. Results: The prevalence of active commuting among schoolchildren was 48.0% (95%CI 45.7-50.4), and it was associated, in the crude analysis, with blood glucose and LDL cholesterol levels. Passive schoolchildren had a 1.1 higher prevalence ratio of high glucose and LDL cholesterol levels. However, when sociodemographic variables were included in the model, these associations were not maintained. Conclusions: The prevalence of active commuting in the sample studied is low and it was shown to have a crude association with glucose and LDL cholesterol levels in students. However, sociodemographic factors seem to influence these associations.
