title: Mycorrhization and saline stress response in Hyptis suaveolens

description: ABSTRACT: The objective of this study was to evaluate the physiological and biochemical mechanisms of adaptation of Hyptis suaveolens under osmotic stress due to salinity inoculations with a mycorrhizal fungal species. H. suaveolens seeds were germinated in polyethylene pots containing a substrate associated with or without arbuscular mycorrhizal fungi (AMF). After plant formation, treatments were treated with different salt concentrations (0.0, 35, 70, and 105 mM) and fungi (control and two types of AMF), totaling 12 treatments with three replicates. The experimental design used randomized blocks in a 4 x 3 factorial scheme, totaling 12 treatments with three replicates each. Salinity affected all measured physiological and biochemical variables, and the stress reduced dry matter content. Plants associated with AMF had increased dry matter compared to non-associated plants, and there were increased biochemical and physiological responses of AMF-colonized plants in the 35 mM NaCl treatment. However, saline stress negatively affected the development of H. suaveolens; and therefore, no attenuation of fungi was observed.

title: Genomic characterization of Canine circovirus detected in a dog with intermittent hemorrhagic gastroenteritis in Brazil

description: ABSTRACT: Because Canine circovirus (CanineCV) is a new species of the genus Circovirus, several issues related to its epidemiology, pathogenesis and clinical disease remain unknown. Thus, this study aimed to perform the characterization of the first complete genome sequence of CanineCV detected in a dog with diarrhea in Brazil. A stool sample was collected of a ten-month-old female German Shepherd dog which had signs of intermittent hemorrhagic gastroenteritis, vomiting, and a history of eating raw pork. The complete CanineCV genome was sequenced by Next-Generation Sequencing. The sequence had 2,063 nucleotides, showed a typical genomic organization for circovirus, and was grouped with strain 214 described in the United States by phylogenetic analysis. One amino acid change was found in the replicase protein, and because of that it was considered unique to CanineCV. Therefore, the characterization of the complete genome of Brazilian CanineCV can be used in future studies of molecular epidemiology, pathogenesis and development of diagnostic tools for the prevention and control of this disease.

title: Determinants of the exclusive breastfeeding abandonment: psychosocial factors

description: OBJECTIVE To assess the determinants of exclusive breastfeeding abandonment. METHODS Longitudinal study based on a birth cohort in Viçosa, MG, Southeastern Brazil. In 2011/2012, 168 new mothers accessing the public health network were followed. Three interviews, at 30, 60, and 120 days postpartum, with the new mothers were conducted. Exclusive breastfeeding abandonment was analyzed in the first, second, and fourth months after childbirth. The Edinburgh Postnatal Depression Scale was applied to identify depressive symptoms in the first and second meetings, with a score of ≥ 12 considered as the cutoff point. Socioeconomic, demographic, and obstetric variables were investigated, along with emotional conditions and the new mothers’ social network during pregnancy and the postpartum period. RESULTS The prevalence of exclusive breastfeeding abandonment at 30, 60, and 120 days postpartum was 53.6% (n = 90), 47.6% (n = 80), and 69.6% (n = 117), respectively, and its incidence in the fourth month compared with the first was 48.7%. Depressive symptoms and traumatic delivery were associated with exclusive breastfeeding abandonment in the second month after childbirth. In the fourth month, the following variables were significant: lower maternal education levels, lack of homeownership, returning to work, not receiving guidance on breastfeeding in the postpartum period, mother’s negative reaction to the news of pregnancy, and not receiving assistance from their partners for infant care. CONCLUSIONS Psychosocial and sociodemographic factors were strong predictors of early exclusive breastfeeding abandonment. Therefore, it is necessary to identify and provide early treatment to nursing mothers with depressive symptoms, decreasing the associated morbidity and promoting greater duration of exclusive breastfeeding. Support from health professionals, as well as that received at home and at work, can assist in this process.

title: Socioeconomic inequalities in the access to and quality of health care services

description: OBJECTIVE To assess the inequalities in access, utilization, and quality of health care services according to the socioeconomic status. METHODS This population-based cross-sectional study evaluated 2,927 individuals aged ≥ 20 years living in Pelotas, RS, Southern Brazil, in 2012. The associations between socioeconomic indicators and the following outcomes were evaluated: lack of access to health services, utilization of services, waiting period (in days) for assistance, and waiting time (in hours) in lines. We used Poisson regression for the crude and adjusted analyses. RESULTS The lack of access to health services was reported by 6.5% of the individuals who sought health care. The prevalence of use of health care services in the 30 days prior to the interview was 29.3%. Of these, 26.4% waited five days or more to receive care and 32.1% waited at least an hour in lines. Approximately 50.0% of the health care services were funded through the Unified Health System. The use of health care services was similar across socioeconomic groups. The lack of access to health care services and waiting time in lines were higher among individuals of lower economic status, even after adjusting for health care needs. The waiting period to receive care was higher among those with higher socioeconomic status. CONCLUSIONS Although no differences were observed in the use of health care services across socioeconomic groups, inequalities were evident in the access to and quality of these services.

title: Association between food assistance program participation and overweight

description: OBJECTIVE The objective of this study was to investigate the association between food assistance program participation and overweight/obesity according to poverty level. METHODS A cross-sectional analysis of data from 46,217 non-pregnant and non-lactating women in Lima, Peru was conducted; these data were obtained from nationally representative surveys from the years 2003, 2004, 2006, and 2008-2010. The dependent variable was overweight/obesity, and the independent variable was food assistance program participation. Poisson regression was used to stratify the data by family socioeconomic level, area of residence (Lima versus the rest of the country; urban versus rural), and survey year (2003-2006 versus 2008-2010). The models were adjusted for age, education level, urbanization, and survey year. RESULTS Food assistance program participation was associated with an increased risk of overweight/obesity in women living in homes without poverty indicators [prevalence ratio (PR) = 1.29; 95% confidence interval (CI) 1.06;1.57]. When stratified by area of residence, similar associations were observed for women living in Lima and urban areas; no associations were found between food assistance program participation and overweight/obesity among women living outside of Lima or in rural areas, regardless of the poverty status. CONCLUSIONS Food assistance program participation was associated with overweight/obesity in non-poor women. Additional studies are required in countries facing both aspects of malnutrition.

title: The role of Candida albicans in root caries biofilms: an RNA-seq analysis

description: Abstract Objective This study sought to analyze the gene expression of Candida albicans in sound root surface and root caries lesions, exploring its role in root caries pathogenesis. Methodology The differential gene expression of C. albicans and the specific genes related to cariogenic traits were studied in association with samples of biofilm collected from exposed sound root surface (SRS, n=10) and from biofilm and carious dentin of active root carious lesions (RC, n=9). The total microbial RNA was extracted, and the cDNA libraries were prepared and sequenced on the Illumina Hi-Seq2500. Unique reads were mapped to 163 oral microbial reference genomes including two chromosomes of C. albicans SC5314 (14,217 genes). The putative presence of C. albicans was estimated (sum of reads/total number of genes≥1) in each sample. Count data were normalized (using the DESeq method package) to analyze differential gene expression (using the DESeq2R package) applying the Benjamini-Hochberg correction (FDR&lt;0.05). Results Two genes (CaO19.610, FDR=0.009; CaO19.2506, FDR=0.018) were up-regulated on SRS, and their functions are related to biofilm formation. Seven genes ( UTP20 , FDR=0.018; ITR1 , FDR=0.036; DHN6 , FDR=0.046; CaO19.7197 , FDR=0.046; CaO19.7838 , FDR=0.046; STT4 , FDR=0.046; GUT1 , FDR=0.046) were up-regulated on RC and their functions are related to metabolic activity, sugar transport, stress tolerance, invasion and pH regulation. The use of alternative carbon sources, including lactate, and the ability to form hypha may be a unique trait of C. albicans influencing biofilm virulence. Conclusions C. albicans is metabolically active in SRS and RC biofilm, with different roles in health and disease.

title: Selectivity and feeding behavior of Saanen goats subjected to three nutritional levels

description: ABSTRACT This study was conducted to investigate the effect of selective feeding habits on the quality of the ingested diet and the effect of feed restriction on the selectivity and behavior of goats in feedlots. Differences were found only in the amount of feed given to the animals, with a difference in the amount of feed rejected as a function of the nutritional level. Higher levels of orts were measured for those animals that received the ad libitum diet. For the composition of orts, differences were measured only in the ether extract fraction. Animals fed the ad libitum diet increased their intake of ether extract and energy, crude fiber, neutral detergent fiber, and acid detergent fiber. Thus, they had a preference for consuming the fibrous and energetic portions of the diet to the detriment of the mineral matter. The granulometry influenced the leftovers for the male and female treatments only in the diet that contained the 2.00- and 0.063-mm sized particles, with larger leftovers for the females. There were statistical differences as a function of feeding level for time spent in rumination, with stereotypical behavior, and in time spent standing up or lying down. As a function of sex, the differences were the same variables, including the time spent with agonistic behavior. Animals that received the ad libitum diet had a greater gain and final weight, whereas the animals that received the 60% restricted diet had the lowest performance, as did the females. Feed restriction changed the natural feeding behavior of goats, with smaller feed particles preferred. The feed restriction and sex also influenced the time spent on nonproductive activities, and the animals became more restless, with females having a higher social behavior than males.

title: Congenital hepatic fibrosis associated with ascites in a nellore calf

description: ABSTRACT: Congenital hepatic fibrosis (CHF) is an autosomal recessive malformation characterized by a variable degree of fibrosis and bile duct proliferation, mainly described in people and rarely reported in bovine European breeds. In addition to liver fibrosis, this syndrome has been associated with ascites and subcutaneous edema in calves. This paper described the pathological findings of the first report of CHF in a Nelore bovine fetus. A stillborn calf was removed by cesarean section because of dystocia. At necropsy, characteristic changes of CHF were observed, such as a large increase in abdominal volume associated with hepatic fibrosis and marked subcutaneous edema. Histological examination of liver revealed periportal and port-portal islands of fibrosis separating the parenchyma into nodules of variable sizes and containing numerous abnormally shaped bile ducts. The CHF should be considered in the differential diagnosis in young calves that present with ascites.
