title: Hepatitis B and C in the areas of three Regional Health Centers of Pará State, Brazil: a spatial, epidemiological and socioeconomic analysis

description: Abstract Background Viral hepatitis is a serious public health problem and is related to the different socioeconomic characteristics of the Brazilian territory. Objective To analyze the spatial distribution of the hepatitis B and C and their relationship with the Municipal Human Development Index (IDHM), in the areas of three Regional Health Centers (CRS), in the state of Pará, Brazil, from 2010 to 2014. Method In this descriptive and cross-sectional study, data from the Information System for Notifiable Diseases of the Ministry of Health and the 2010 Census of the Brazilian Institute of Geography and Statistics were used. Results The analyses showed that the 11th CRS reported the greater number of cases (60.9%). The most affected individuals by both diseases were female, brown skin color, adults and elementary school degree. The most significant risk factors were injecting drugs use, dental and surgical treatments. It was observed spatial dependence between the IDHM and the diseases incidence rate parameters, with direct and indirect autocorrelations. Thus, areas with medium and low IDHM showed high incidence rates, especially in municipalities with intense migratory flows, in the last decades. Conclusion The analyses were effective for construct epidemiological scenarios of the diseases. The need to expand the control of hepatitis in the studied areas is highlighted.

title: Gender as a marker of informal care relations in mental health

description: Abstract Background The gender interface as an important category in the field of mental health is still incipient. This results in the reification of practices that reproduce inequalities and asymmetries between men and women caregivers in the context of psychiatric care in Brazil. Objective To discuss how gender has marked care practices performed by families through the identification of differences in socio-demographic profile, development of care activities and their repercussions on the family's life according to the sex of the individuals. Method A cross-sectional study with 1242 relatives of users of Psychosocial Care Centers. We verified the prevalence of each variable stratum according to the sex of the individuals studied using chi-square test for heterogeneity. Results Aspects such as absence of the division of care activity, feeling of overload, poor quality of life, dissatisfaction with family relationships, and manifestation of minor psychiatric disorders were more prevalent among the women accessed. Conclusion There are important differences between men and women caregivers in mental health, especially regarding the repercussions of care on the lives of these people.

title: SPECT/CT with 99mTc-sestamibi for the evaluation of skeletal muscle perfusion after electrical muscle stimulation in athletes

description: Abstract Objective: The purpose of this study was to evaluate the effects of electrical muscle stimulation (EMS) on muscles, using 99mTc-sestamibi SPECT/CT. Materials and Methods: We prospectively enrolled 20 consecutive male professional water polo players. The mean age was 25 years (range, 18-36 years). All athletes underwent 99mTc-sestamibi SPECT/CT of the thigh (rectus femoris and vastus medialis muscle groups) before and after EMS. Images were quantified to identify increases in perfusion after EMS. Results: Before EMS, there were no significant differences between the right and left thigh (rectus femoris and vastus medialis muscles) in terms of perfusion (p = 0.4). However, the comparison between the pre- and post-EMS analyses of the same muscle groups showed significant differences in radiotracer uptake (p &lt; 0.001), with a mean increase in perfusion of 128% for the rectus femoris muscle group (95% CI: 0.86-1.61) and 118% for the vastus medialis muscle group (95% CI: 0.96-1.79). Conclusion: 99mTc-sestamibi SPECT/CT is an objective means of evaluating blood flow in muscles submitted to EMS, which appears to promote significant increases in such blood flow.

title: Prevalence of overweight and obesity in the first year of life in the Family Health Strategies

description: Abstract Background Childhood overweight and obesity represent one of the main public health problems in the world, but there is a scarcity of prevalence records in Brazil during the first year of life. Objective Verify the prevalence of overweight and obesity in the first year of life of infants enrolled in the Family Health Strategies, and to identify whether there is a difference in weight-per-age, height-per-age, weight/height-per-age and body mass index (BMI)-per-age in relation to sex, age group and socioeconomic level. Method A cross-sectional study was performed, in which weight and height data were collected from the Child Health Handbook. Results The prevalence of overweight and obesity was 7.2% according to the weight/height index, and 4.8% for the BMI index. Infants with an A-B socioeconomic status had higher BMI-per-age when compared to children at level C (p=0.048). Infants aged 6 to 12 months had higher weight-per-age (p=0.02) and height-per-age (p=0.01) than infants younger than six months. Conclusion The prevalence of overweight and obesity in the first year of life depends on the index used for classification. The socioeconomic status may interfere with BMI-per-age values, and the age group may interfere with weight-per-age and height-per-age indexes.

title: Influence of forage production area, concentrate supply, and workforce on productive results in milk production systems

description: ABSTRACT This study aimed to investigate the influence of forage production area, concentrate supply, and farm labor on characterization of milk production systems (MPS) and their productive results. Milk volume data provided in 2014 by 110 dairy farms located in the eastern region of Santa Catarina State, Brazil, were obtained from a dairy industry. Forty-four farms with different production levels were selected, in which interviews were carried out aiming to characterize the management practices related to forage production area, concentrate supply, and farm labor. A principal component analysis (PCA) was performed. Then, regressions were made between the principal components (PC) and indicator variables of productive response (annual milk production, milk production per area, milk production per cow, milk production per worker on farm, and number of cows per hectare). Finally, we performed a hierarchical agglomerative cluster analysis based on the PCA, followed by comparison of the means between clusters. Three PC were generated: indicator of scale and intensification, indicator of age of the manager and his experience on dairy farming, and indicator of specialization and permanent family labor available. The three PC were influencing the production results, especially PC1. It was possible to form five clusters: cluster 1, characterized by the highest value in PC1, showed the highest production results, followed by the cluster 2, with intermediate values in PC1; clusters 3, 4, and 5, characterized by lower values in PC1 and distinguished by PC2 and PC3, had the lowest productive results. Aspects related to forage production area, concentrate supply, and workforce are important for MPS characterization and have significant influence on productive results.

title: Do family arrangements affect parents’ decision of school for their children?

description: Abstract This study aims to analyze whether family arrangements (single-parent or two-parent) influence the choice of school system (public or private) for children. For this analysis, data from the 2015 National Household Sample Survey (PNAD) were used. Results point to dissimilarities among family arrangements which can be explained by differences in individual preferences as well as in family income. We found that families are more likely to invest privately in early childhood education. The evidence may be due to the small number of public day care centers. According to the order of birth, families can invest in their eldest child to the detriment of their other children, in the case of female single-parent and two-parent family arrangements. In addition, we found that male children were less likely to study in a private school in female single-parent arrangement. This result may show mothers’ wishes to encourage daughters to study in an attempt to empower them.

title: Association of smoking with redox biomarkers and cardiometabolic risk factors in elder individuals

description: Abstract Background Smoking is the leading cause of preventable death worldwide, and is considered an important risk factor for cardiovascular disease (CVD). Objective To investigate the association of smoking with sex, redox metabolism and cardiometaboic risk factors of 381 elderly from the Family Health Strategy of Porto Alegre. Method To categorize smoking, followed by the recommendations of the Center for Disease Control (CDC). We studied the following oxidative stress markers investigated: advanced products of protein oxidation (AOPP), nitric oxide metabolites (NOx), the antioxidant capacity was measured by Ferric Reducing Ability of Plasma (FRAP). Cardiometabolic risk factors were also evaluated. Results Regarding sex/smoking, women are more often non-smokers (P = 0.001). Former male smokers had higher concentrations of FRAP (P = 0.001), and smokers had higher concentration of NOx (0.012), lower average waist circumference-WC (P = 0.017), body mass index-BMI (P = 0.003) and increased HDL-c levels (P = 0.003). There were found significant results among women. Conclusion The elderly male smokers presented lower values of WC, BMI and HDL-c, but smokers presented increased NOx concentration, which is a oxidative stress biomarker associated with cardiovascular diseases. Therefore, it is important to emphasize the importance in preventing and adhering to smoking cessation to avoid cardiovascular comorbidities..

title: Improvement of Polypropylene Adhesion by Kraft Lignin Incorporation

description: Low surface energy and poor adhesion are well-known characteristics of polypropylene (PP). Surface treatments such as plasma, corona, and laser are usually applied to overcome these limitations. However, current studies highlight the incorporation of hydrophilic or amphiphilic polymers into hydrophobic low-surface-energy polymers as an alternative for increasing surface energy and thus improving adhesion. Lignin could be a promising amphiphilic polymer for use in increasing surface energy. In this work, PP/kraft lignin composites were obtained by incorporating up to 5 wt% of kraft lignin (KL) into a PP matrix. Corona treatment was applied to pristine PP and composites surfaces. Contact angle measurements and peeling tests were carried out to investigate the effects of KL incorporation and corona treatment on the surface energy and the mechanical strength of adhesion. Differential scanning calorimetry (DSC) was used to evaluate the PP’s crystallinity index and recrystallization temperature and to dismiss their effects on the surface energy changes. Scanning electron microscopy (SEM) was applied to investigate the lignin dispersion. The results show that KL incorporation has potential as a method to improve the surface energy of PP, improve its poor adhesion, and enhance the effects of corona treatment.

title: CORRELATION BETWEEN LUMBAR SPINAL STENOSIS BASED ON MORPHOLOGY OF THE DURAL SAC AND THE QUALITY OF LIFE

description: ABSTRACT Objective: To evaluate the possible existence of a significant correlation between quality of life and severity classification of lumbar stenosis based on dural sac morphology in outpatients. Methods: Forty patients with a diagnosis of lumbar stenosis followed at a university hospital were submitted to magnetic resonance imaging (MRI) and quality of life questionnaires: Oswestry Disability Index (ODI), SF-36, Swiss Spinal Stenosis Questionnaire (SSS) and EQ-5D. They were classified as type A, B, C or D based on MRI. For the statistical analysis, the Spearman correlation was used. Results: Seventeen female patients and 23 male patients with mean age of 56.5 years constituted the sample. ODI had a mean dysfunction of 44.9%, the PCS score averaged 29.9, the MCS score was 41.3. The general symptoms of SSS presented a mean of 3.2 and the EQ-5D presented an average of 0.491. The patients with the highest severity in the classification were not necessarily those who presented worse scores in the quality of life questionnaires. Conclusion: The classification of severity of the lumbar spinal stenosis based on dural sac morphology does not correlate with the applied quality of life questionnaires. Level of Evidence III; Cross-sectional observational study.
