This study was aimed at describing the community of arthropod ectoparasites associated with sympatric populations of Turdus amaurochalinus and Turdus rufiventris and analyzing the aggregation patterns of the chewing lice species, during reproductive and nonreproductive periods, of both Turdus species in three areas of the Atlantic forest in southern Rio(More)
BACKGROUND Dyspepsia is common among end-stage renal disease (ESRD) patients and its association with delayed gastric emptying is not well established. We assessed the association of dyspepsia with gastric emptying time in ESRD patients undergoing hemodialysis (HD). METHODS Dyspepsia was assessed through the Porto Alegre Dyspeptic Symptoms Questionnaire(More)
OBJECTIVE The objective of this study was to evaluate the effect of daily and weekly iron supplementation compared with control on hemoglobin values and anemia prevalence in infants. METHODS In this cluster-randomized study, we evaluated infants aged 12-24 months (n = 210) from three public daycare centers, during 4 months. Intervention-group A was(More)
OBJECTIVE To determine the correlation between depression and quality of life (QOL) of patients in hemodialysis (HD). METHOD One hundred and sixty six patients over 18 years of age who had been in HD for at least three months and had no history of transplant. QOL was assessed using the SF-36. To categorize depression, a score > 10 was used on the 10-item(More)
Quality of life (QOL) is an important outcome among end-stage renal disease patients and can be associated with modifiable behaviors. We analyzed the correlation between coping style and QOL among hemodialysis patients. We studied 166 end-stage renal disease patients undergoing hemodialysis. They were older than 18 years, under hemodialysis for at least 3(More)
BACKGROUND Several aspects linked to social are involved in the onset of depressive feelings. We aimed to find out if social adaptability and substance abuse predict depression among end-stage renal disease (ESRD) patients undergoing hemodialysis (HD). METHODS We included 145 ESRD patients undergoing HD. Social adaptability was estimated by the Social(More)
Depression is common in patients on hemodialysis (HD), and its treatment fails in many cases. Among women on HD, sexual dysfunction (SD) can be an underestimated cause of depression and an impending factor for successful therapy. We aimed to evaluate the association between SD and depression among end-stage renal disease (ESRD) women undergoing HD and to(More)
Microdeletions in Yq are associated with defects in spermatogenesis, while those in the AZF region are considered critical for germ cell development. We examined microdeletions in the Y chromosomes of patients attended at the Laboratory of Human Reproduction of the Clinical Hospital of the Federal University of Goiás as part of a screening of patients who(More)
Biotinylation is proposed for the identification of surface proteins in Schistosoma mansoni using the streptavidin-HRP conjugate for the detection of labeled polypeptides. However, control samples also showed several endogenous biotinylated polypeptides. In an attempt to determine the possibility of nonspecific binding between the streptavidin-HRP conjugate(More)
Food fortification is advocated to tackle iron deficiency in anemic populations. Our objective was to evaluate the impact of iron-fortified rice (Ultrarice(®)) weekly on hemoglobin and anemia levels compared with standard rice (control). This cluster-randomized study deals with infants (10-23 months) from two public child day care centers in Brazil, n =(More)
