CONTEXT AND OBJECTIVE: In 2004, the Brazilian National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, ANVISA) published a resolution establishing guidelines for albumin use. Although the published data do not indicate any definitive conclusions about the benefits of albumin use in patients with nephrotic syndrome (NS), the guidelines recommend this procedure only in cases of edema that is refractory to use of diuretics. The aim here was to analyze albumin use among patients with nephrotic syndrome. DESIGN AND SETTING: Pharmacoeconomic study conducted in four large public referral hospitals for nephrology services in northeastern Brazil. METHOD: Cost-effectiveness and cost-utility economic evaluations were performed on a concurrent cohort of patients with nephrotic syndrome, who were divided into two groups according to compliance or noncompliance with the guidelines. Quality-of-life data were obtained from the SF36 and CHQ-PF50 questionnaires. RESULTS: This study enrolled 109 patients (60% adults and 56% women); 41.3% were using albumin in accordance with the guidelines. The weight, diuresis and fluid balance parameters were more cost-effective for patients who adhered to the guidelines. Regarding days of hospitalization avoided, the incremental ratio showed a daily cost of R$ 55.33, and guideline-compliant patients were hospitalized for five days or fewer. The quality of life improved by 8%, and savings of R$ 3,458.13/QALY (quality-adjusted life year) for the healthcare system were generated through guideline compliance. CONCLUSION: The economic analyses of this study demonstrated that there were greater cost benefits for patients whose treatment followed the guidelines. © 2017, Associacao Paulista de Medicina.

Background: Pain is an unpleasant sensory and emotional experience. Both chronic pain and depression result in substantial disability reduced HRQoL and increased health care costs and utilization. Objectives: To evaluate the strength of the association between depressive and anxiety symptoms and chronic pain, and to investigate the impact of these symptoms on health-related quality of life (HRQoL) in chronic pain individuals. Methods: Pain was assessed by means of a Visual Analogue Scale (VAS). Depressive and anxiety symptoms were assessed by the Hospital Anxiety and Depression (HAD) scale. Quality of life was assessed by means of the SF-36. Results: Four hundred patients were studied, mean age 45.6 ± 11.4 years and 82.8% female gender. According to HAD, 70% had anxiety and 60% depression symptoms. SF-36 showed mean scores ≤ 50% for all the domains. Patients with severe pain/extreme (70.4%) had a higher frequency of anxiety than those with pain selvagem/moderada (59,5%). This was a statistically significant (p = 0.027). However, the frequency of depression did not reach statistical significance when both groups were compared p = 0.109). Discussion: Depressive/anxiety symptoms and pain together have worse clinical outcomes than each condition alone.

Genetic Epidemiology | Year: 2013
Characterization of genetic admixture of populations in the Americas and the Caribbean is of interest for anthropological, epidemiological, and historical reasons. Asthma has a higher prevalence and is more severe in populations with a high African component. Association of African ancestry with asthma has been demonstrated. We estimated admixture proportions of samples from six trihybrid populations of African descent and determined the relationship between African ancestry and asthma and total serum IgE levels (tIgE). We genotyped 237 ancestry informative markers in asthmatics and nonasthmatic controls from Barbados (190/277), Jamaica (177/529), Brazil (40/220), Colombia (508/625), African Americans from New York (207/171), and African Americans from Baltimore/Washington, D.C. (625/757). We estimated individual ancestries and evaluated genetic stratification using Structure and principal component analysis. Association of African ancestry and asthma and tIgE was evaluated by regression analysis. Mean ± SD African ancestry ranged from 0.76 ± 0.10 among Barbadians to 0.33 ± 0.13 in Colombians. The European component varied from 0.14 ± 0.05 among Jamaicans and Barbadians to 0.26 ± 0.08 among Colombians. African ancestry was associated with risk for asthma in Colombians (odds ratio (OR) = 4.5, P = 0.001) Brazilians (OR = 136.5, P = 0.003), and African Americans of New York (OR: 4.7; P = 0.040). African ancestry was also associated with higher tIgE levels among Colombians (β = 1.3, P = 0.04), Barbadians (β = 3.8, P = 0.03), and Brazilians (β = 1.6, P = 0.03). Our findings indicate that African ancestry can account for, at least in part, the association between asthma and its associated trait, tIgE levels. © 2013 Wiley Periodicals, Inc.

Determination of the neutrophil gelatinase-associated lipocalin (NGAL) level can be used to detect acute kidney injury (AKI) earlier than determination of the serum creatinine (SCr) level in settings such as cardiac surgery, contrast nephropathy, and intensive care units. We hypothesized that urine NGAL (UrNGAL) would be an early biomarker of drug nephrotoxicity. To test this, we studied hemodynamically stable patients treated with amphotericin B (AmB). We measured the SCr and UrNGAL levels at the baseline and daily after initiation of AmB up to day 14 or development of AKI by the use of the SCr criterion. AKI was defined according to a Kidney Disease: Improving Global Outcomes (KDIGO) criterion (an increase in the SCr level by 0.3 mg/dl within 48 h or an SCr level 1.5 times the baseline level within 7 days). We studied 24 patients with a mean age of 48.4 16.4 years. Most patients were male, and the patients received AmB (12 received AmB deoxycholate and 12 received liposomal AmB) for the treatment of leishmaniasis (91.7%). Overall, 17/24 patients fulfilled a KDIGO criterion for AKI. Peak UrNGAL levels were higher in patients with AKI than in patients without AKI and in recipients of AmB deoxycholate than in recipients of liposomal AmB. The diagnostic performance of the UrNGAL level on day 5 for the detection of AKI was moderate, with the area under the curve (AUC) being 0.68 (95% confidence interval [CI], 0.41 to 0.95). In the subgroup receiving AmB deoxycholate, however, the AUC rose to 0.89 (95% CI, 0.67 to 1.00). In a patient-level analysis, we found that AKI could be detected 3.2 days earlier by the use of the UrNGAL criterion than by the use of the SCr criterion (times to AKI by the UrNGAL and SCr criteria, 3.7 2.5 versus 6.9 3.3 days, respectively; P = 0.001). Future studies should evaluate if a treatment strategy oriented toward evaluation of UrNGAL levels will improve outcomes. These findings for AmB-induced AKI in leishmaniasis patients could serve as a basis for the investigation of urine biomarkers in the early detection of drug nephrotoxicity in other clinical settings.

Introduction and objectives: We evaluated the sensitivity and specificity of morphological criteria for the diagnosis of prostate adenocarcinoma in consecutive, prostate needle biopsies specimens with emphasis on the location and number of nucleoli. Methods: The morphological features of 387 consecutive prostate needle biopsies specimens, in 2013, were systematically examined and stratified according to the final diagnosis of benign, suspicious and malignant lesions. We also tested how well each criterion predicted the final diagnosis after the immunohistochemical evaluation for expression of the basal cell markers (p63 and high molecular weight cytokeratin) and racemase. Results: A prominent nucleoli is the most common feature of carcinoma; however it is also relatively common in benign cases. The frequencies of prominent central nucleoli in malignant, suspicious and benign cases were 99%, 89% and 27%, respectively. Marginated nucleoli (85%, 60% and 7%), double nucleoli (86%, 53% and 10%), and multiple nucleoli (47%, 14% and 2%) were less common in benign cases, with significant difference among the groups. From the 36 cases initially diagnosed as suspicious, the presence of marginated nucleoli and mitoses were associated with the final diagnosis of malignancy. Prominent central nucleoli were more associated with cases which the final diagnosis after immunohistochemistry was benign. Conclusion: The location and number of nucleoli may be valuable morphological markers to identify suspicious lesions, since these features are more specific for malignancy than nucleolar prominence. The presence of prominent nucleoli commonly leads to the initial diagnosis of suspicious lesion that, subsequently, will be resulted in benignity confirmed by immunohistochemistry. © 2016, Sociedade Brasileira de Pneumologia e Tisiologia.

Background: IL-13 is a signature cytokine of the helper T cell type 2 (TH2) pathway which underlies host defense to helminthic infection and activates production of IgE in both parasitized populations and in urban settings after allergen exposure. Methodology/Principal Findings: Two functional polymorphisms in IL13, rs1800925 (or c.1-1111C>T) and rs20541 (or R130Q) were previously found to be associated with Schistosoma hematobium infection intensity. They have not been thoroughly explored in S. mansoni-endemic populations, however, and were selected along with 5 tagging SNPs for genotyping in 812 individuals in 318 nuclear families from a schistosomiasis-endemic area of Conde, Bahia, in Brazil. Regression models using GEE to account for family membership and family-based quantitative transmission disequilibrium tests (QTDT) were used to evaluate associations with total serum IgE (tIgE) levels and S. mansoni fecal egg counts adjusted for non-genetic covariates. We identified a protective effect for the T allele at rs20541 (P = 0.005) against high S. mansoni egg counts, corroborated by QTDT (P = 0.014). Our findings also suggested evidence for protective effects for the T allele at rs1800925 and A allele at rs2066960 after GEE analysis only (P = 0.050, 0.0002). Conclusions/Significance: The two functional variants in IL13 are protective against high S. mansoni egg counts. These markers showed no evidence of association with tIgE levels, unlike tIgE levels previously studied in non-parasitized or atopic study populations. © 2012 Grant et al.

To evaluate the association between personality disorders (PDs) and suicide attempts (SAs) in euthymic patients with type I bipolar disorder (BD).One-hundred twenty patients with type I BD, with and without history of SA, were evaluated during euthymia. The assessment included a clinical and sociodemographic questionnaire, the Hamilton Depression Rating Scale, the Young Mania Rating Scale, the Barratt Impulsiveness Scale, and Structured Clinical Interviews for DSM-IV Axis I and II Disorders. Logistic regression was employed to determine associations between history of SA and patient characteristics.History of SA was significantly associated with comorbid axis I disorder, rapid cycling, high impulsivity (attentional, motor, non-planning, and total), having any PD, and cluster B and C PDs. Only cluster B PDs, high attentional impulsivity, and lack of paid occupation remained significant after multivariate analysis.Cluster B PDs were significantly associated with SA in patients with type I BD. High attentional impulsivity and lack of gainful employment were also associated with SA, which suggests that some cluster B clinical and social characteristics may exacerbate suicidal behavior in this population. This finding offers alternatives for new therapeutic interventions.

HTLV-1 is the causal agent of Adult T cell Leukemia/lymphoma (ATLL) and HTLV-1-associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP). The immune response to HTLV-1-infection is polarized to the Th1-type, and the presence of CXCL9/CXCL10 chemokines may lead to an increase in the recruitment of pro-inflammatory molecules in spinal cord tissue, contributing to the damage observed in the development of HAM/TSP. It has been observed that in chronic helminth-infections, such as schistosomiasis, there is a deviation toward the Th2/regulatory immune response.To evaluate the ability of Schistosoma spp. proteins to decrease the in vitro CXCL9 and CXCL10 production by PBMC of HTLV-1-infected individuals.The Schistosoma proteins rSm29, rSh-TSP-2 and PIII were added to PBMC cultures of HTLV-1-infected individuals and the levels of chemokines in the supernatants were measured using a sandwich ELISA method.The addition of rSm29 to the cultures resulted in decreased production of CXCL9 in all the analyzed individuals and HAM/TSP group (181679727pg/mL, p=0.044; 202376023pg/mL, p=0.028, respectively) compared to the levels in unstimulated cultures (197459729pg/mL; 250782392pg/mL, respectively). The addition of rSh-TSP-2 decreased the production of CXCL9 in all studied individuals and carriers group (161369233pg/mL, p=0.031; 139778857pg/mL, p=0.026) vs unstimulated cultures (197459729pg/mL; 1812110508pg/mL, respectively). Addition of PIII did not alter the results. There was no significant change in the levels of CXCL10 by the addition of the studied proteins.The Schistosoma proteins used in this study were able to down modulate the production of CXCL9, a chemokine associated with the inflammatory process in HTLV-1-infection.

Recent data suggest that up to 21% of positive circumferential margins (PCM) and 47% of extraprostatic extension (EPE) samples may be missed when partial embedding methods are employed. Kim and colleagues (2009) suggested that total inclusion of the periphery (3mm rim) of the prostate prevented the failure to detect PCM and EPE.Radical prostatectomy specimen (n=148) slides were reviewed after adoption of a protocol that included a 3 mm rim of peripheral tissues. We evaluated whether the analysis of supplemental slides of prostate periphery changed margin status, presence of EPE, Gleason score and extent of PCM and EPE.Partial sampling resulted in missing 29% of PCM and 20% of EPE without using data from the supplemental slides of prostate periphery. Changes from focal to extensive disease were found in 11/21 (52%) cases of positive circumferential margins and in 5/13 (38%) cases of extraprostatic extension. Changes in the Gleason score were uncommon.These results indicate the importance of including all the prostate peripheral tissue for microscopic analysis when partial embedding methods are adopted.

Earlier we reported on growth and adiposity in a cross-sectional study of disadvantaged Brazilian preschoolers. Here we extend the work on these children, using structural equation modelling (SEM) to gather information on the complex relationships between the variables influencing height and adiposity. We hope this information will help improve the design and effectiveness of future interventions for preschoolers.In 376 preschoolers aged 3-6 years attending seven philanthropic daycares in Salvador, we used SEM to examine direct and indirect relationships among biological (sex, ethnicity, birth order, maternal height and weight), socio-economic, micronutrient (haemoglobin, serum selenium and zinc), and environmental (helminths, de-worming) variables on height and adiposity, as reflected by Z-scores for height-for-age (HAZ) and body mass index (BMIZ).Of the children, 11% had HAZ<-1, 15% had WHZ<-1, and 14% had BMIZ>1. Of their mothers, 8% had short stature, and 50% were overweight or obese. Based on standardized regression coefficients, significant direct effects (p<0.05) for HAZ were maternal height (0.39), being white (-0.07), having helminth infection (-0.09), and serum zinc (-0.11). For BMIZ, significant direct effects were maternal weight (0.21), extremely low SES (-0.15), and haemoglobin (0.14). Indirect (p<0.05) effects for HAZ were sex (being male) (-0.02), helminth infection (-0.01), de-worming treatment (0.01), and serum selenium (-0.02), and for BMIZ were extremely low SES (-0.001), helminth infection (-0.004), and serum selenium (0.02).Of the multiple factors influencing preschoolers growth, helminth infection was a modifiable risk factor directly and indirectly affecting HAZ and BMIZ, respectively. Hence the WHO de-worming recommendation should include preschoolers living in at-risk environments as well as school-aged children.
