Clinical and epidemiological profiles of individuals with drug-resistant tuberculosis

Drug-resistant tuberculosis (TB) is a growing global threat. Approximately 450,000 people developed multidrugresistant TB worldwide in 2012 and an estimated 170,000 people died from the disease. This paper describes the sociodemographic, clinical-epidemiological and bacteriological aspects of TB and correlates these features with the distribution of anti-TB drug resistance. Mycobacterium tuberculosis (MT) cultures and drug susceptibility testing were performed according to the BACTEC MGIT 960 method. The results demonstrated that MT strains from individuals who received treatment for TB and people who were infected with human immunodeficiency virus were more resistant to TB drugs compared to other individuals (p < 0.05). Approximately half of the individuals received supervised treatment, but most drug-resistant cases were positive for pulmonary TB and exhibited positive acid-fast bacilli smears, which are complicating factors for TB control programs. Primary healthcare is the ideal level for early disease detection, but tertiary healthcare is the most common entry point for patients into the system. These factors require special attention from healthcare managers and professionals to effectively control and monitor the spread of TB drug-resistant cases.

Padrões intergeracionais de violência familiar associada ao abuso de bebidas alcoólicas: um estudo baseado em genogramas

The objective of this study was to analyze intergenerational patterns of alcohol related violence (ARV). An intentional sample comprising 42 family members was selected according to a set of criteria, including history of ARV. A genogram based on anonymous semi-structured taped interviews was created. The Content Analysis pointed to different patterns of repetition of intergenerational ARV. The most recurrent ones were those of lineal consanguinity (father/son) and through marriage. We observed similarities over the generations of each family as regards the pattern of alcohol consumption; the type of violence; the family reaction and the family life cycle in which ARV was intensified. Our results confirm the intergenerational reproduction of ARV. In conclusion, it is important to create intervention strategies to prevent intergenerational repetition of this association of behaviors.

Effects of Yersinia enterocolitica O:3 derivatives on B lymphocyte activation in vivo

The potential sequelae of intestinal infection with Yersinia enterocolitica include reactive arthritis, erythema nodosum, Reiter's syndrome and other autoimmune diseases. The role of the immune response in the pathogenesis of these diseases has not been fully defined, but autoimmune manifestations may be a consequence of the increase in autoantibodies as a result of polyclonal B-cell activation induced by Yersinia. We investigated the effects of Y enterocolitica 0:3 derivatives on B lymphocyte activation in vivo. Groups of five specific pathogen free (SPF) Swiss mice were inoculated with bacterial cell extract, Yersinia outermembrane proteins (Yops) or lipopolysaccharide (LPS) obtained from Y enterocolitica 0:3 and their immunoglobulin-secreting spleen cells were detected by isotype-specific protein A plaque assay. The presence of specific anti-Yersinia antibodies and autoantibodies was determined in mouse sera by ELISA. In all experiments a marked increase in the number of secretory cells of different isotypes was observed as early as the third day after inoculation. IgG and IgM anti-Yersinia antibodies were detected in the sera of all inoculated mice, and autoantibodies against myosin in the sera of those inoculated with bacterial cell extract. The sera from animals stimulated with LPS reacted with myelin, actin and laminin, while the sera from mice inoculated with Yops reacted with myelin, thyroglobulin and cardiolipin. These results suggest that SPF Swiss mice inoculated with any one of the Y enterocolitica derivatives tested exhibited polyclonal activation of B lymphocytes as a result of stimulation by various bacterial components and not only LPS stimulation.

Icodextrin reduces insulin resistance in non-diabetic patients undergoing automated peritoneal dialysis: results of a randomized controlled trial (STARCH)

Insulin resistance is a common risk factor in chronic kidney disease patients contributing to the high cardiovascular burden, even in the absence of diabetes. Glucose-based peritoneal dialysis (PD) solutions are thought to intensify insulin resistance due to the continuous glucose absorption from the peritoneal cavity. The aim of our study was to analyse the effect of the substitution of glucose for icodextrin on insulin resistance in non-diabetic PD patients in a multicentric randomized clinical trial. This was a multicenter, open-label study with balanced randomization (1:1) and two parallel-groups. Inclusion criteria were non-diabetic adult patients on automated peritoneal dialysis (APD) for at least 3 months on therapy prior to randomization. Patients assigned to the intervention group were treated with 2L of icodextrin 7.5%, and the control group with glucose 2.5% during the long dwell and, at night in the cycler, with a prescription of standard glucose-based PD solution only in both groups. The primary end-point was the change in insulin resistance measured by homeostatic model assessment (HOMA) index at 90 days. Sixty patients were included in the intervention (n = 33) or the control (n = 27) groups. There was no difference between groups at baseline. After adjustment for pre-intervention HOMA index levels, the group treated with icodextrin had the lower post-intervention levels at 90 days in both intention to treat [1.49 (95% CI: 1.23-1.74) versus 1.89 (95% CI: 1.62-2.17)], (F = 4.643, P = 0.03, partial η(2) = 0.078); and the treated analysis [1.47 (95% CI: 1.01-1.84) versus 2.18 (95% CI: 1.81-2.55)], (F = 7.488, P = 0.01, partial η(2) = 0.195). The substitution of glucose for icodextrin for the long dwell improved insulin resistance measured by HOMA index in non-diabetic APD patients.

O estudo de matemática nas salas de recursos de escolas do ensino fundamental

Conforme a Declaração de Salamanca, toda criança tem direito fundamental à educação, em particular aquelas com deficiência. Para atender a esta recomendação, os Estados e Municípios brasileiros instalaram salas de recursos (salas para atendimento especial) em diversas escolas. Esta pesquisa vem apresentar uma análise do trabalho realizado com alunos com deficiência nas Salas de Recurso de escolas da cidade de Rio Claro, focando o ensino de matemática. Foi feito um levantamento das escolas que possuem estas salas e cinco delas foram selecionadas para a realização de entrevistas com os professores especialistas. O objetivo foi conversar sobre as dificuldades e potencialidades deste tipo de atendimento especializado, no que diz respeito à matemática. As análises dessas entrevistas indicaram os procedimentos para o atendimento na SR e as abordagens para o ensino de matemática

Detecção de Histophilus somni (Haemophilus somnus) no sêmen bovino mediante reação em cadeia pela polimerase (PCR)

The present study evaluated the use of PCR for Histophilus somni detection in bovine semen. Semen samples were experimentally infected with H. somni at dilutions ranging from 107 to 101 bacteria/mL and subjected to DNA extraction by the phenol/chloroform method, followed by PCR amplification. The amplification products were analyzed by electrophoresis in 8% acrylamide gel. The oligonucleotide primers used yielded an amplification fragment of 400 base pairs from the bacterial DNA. Positive amplification was obtained even for the 101 bacteria/mL dilution. PCR proved to be an efficient method for the detection of H. somni. The results obtained in this study have brought relevant information for the diagnosis of H. somni, justifying the need for the diagnosis of this bacterium in bulls, especially in semen samples that should be free of contamination. The PCR method has shown to be a useful tool for the quality control of semen produced in artificial insemination centers.
