Envolvimento religioso, comportamentos saudáveis e depressão entre adultos com sobrepeso e obesidade / Religious involvement, healthy behavior and depression among overweight and obese adults

Religiosidade/Espiritualidade são consideradas construtos determinantes da saúde, embora a associação entre envolvimento religioso, comportamentos saudáveis e depressão entre os obesos e sobrepesos não foi bem estudada. Este estudo examinou a relação entre características sociodemográficas da religiosidade, hábitos comportamentais (tabagismo, uso de bebidas alcoólicas e atividade física) e sintomas de depressão. A religiosidade foi mensurada pelo Duke University Religion Index (DUREL) e sintomas depressivos pelo Índice de Depressão de Beck em 322 pessoas com sobrepeso e obesidade. Os resultados da regressão de Poison indicam que pacientes com alta ORA praticam atividade física (RP = 1,27; IC 95%: 1,02-1,59), alta NORA são menos propensos a manifestar depressão (RP = 1,28; IC 95%: 1,02-1,61 ), e quem não fuma apresenta maior probabilidade de alta RI comparado com quem fuma (RP = 1,11; IC 95%: 1,01-1,22). Neste estudo, adultos com sobrepeso e obesidade com alto envolvimento religioso está associado com comportamentos mais saudáveis (praticar atividade física e não fumar) e menos sintomas depressivos. A inclusão de estratégias voltadas à religião/espiritualidade pode ser importante para intervenções durante a perda de peso entre obesos e sobrepesos

Evidence for Reductive Genome Evolution and Lateral Acquisition of Virulence Functions in Two Corynebacterium pseudotuberculosis Strains

Ruiz JC, D'Afonseca V, Silva A, et al. Evidence for Reductive Genome Evolution and Lateral Acquisition of Virulence Functions in Two Corynebacterium pseudotuberculosis Strains. PLoS ONE. 2011;6(4): e18551.Background: Corynebacterium pseudotuberculosis, a Gram-positive, facultative intracellular pathogen, is the etiologic agent of the disease known as caseous lymphadenitis (CL). CL mainly affects small ruminants, such as goats and sheep; it also causes infections in humans, though rarely. This species is distributed worldwide, but it has the most serious economic impact in Oceania, Africa and South America. Although C. pseudotuberculosis causes major health and productivity problems for livestock, little is known about the molecular basis of its pathogenicity. Methodology and Findings: We characterized two C. pseudotuberculosis genomes (Cp1002, isolated from goats; and CpC231, isolated from sheep). Analysis of the predicted genomes showed high similarity in genomic architecture, gene content and genetic order. When C. pseudotuberculosis was compared with other Corynebacterium species, it became evident that this pathogenic species has lost numerous genes, resulting in one of the smallest genomes in the genus. Other differences that could be part of the adaptation to pathogenicity include a lower GC content, of about 52%, and a reduced gene repertoire. The C. pseudotuberculosis genome also includes seven putative pathogenicity islands, which contain several classical virulence factors, including genes for fimbrial subunits, adhesion factors, iron uptake and secreted toxins. Additionally, all of the virulence factors in the islands have characteristics that indicate horizontal transfer. Conclusions: These particular genome characteristics of C. pseudotuberculosis, as well as its acquired virulence factors in pathogenicity islands, provide evidence of its lifestyle and of the pathogenicity pathways used by this pathogen in the infection process. All genomes cited in this study are available in the NCBI Genbank database (http://www.ncbi.nlm.nih.gov/genbank/) under accession numbers CP001809 and CP001829

Combination of preoperative pulmonary and nutritional preparation for esophagectomy

<div><p>Abstract Purpose: To compare pulmonary and nutritional parameters before and after inspiratory muscle training (IMT) and enteral feeding support in patients with esophageal disease undergoing preoperative outpatient follow-up. Methods: Thirty patients with a mean age of 55.83 years, 16 men and 14 women, were included. Pulmonary assessment consisted of the measurement of MIP, MEP, and spirometry. Anthropometric measurements and laboratory tests were performed for nutritional assessment. After preoperative evaluation, inspiratory muscle training and enteral nutrition support were started. A p<0.05 was considered statistically significant. Results: After an outpatient follow-up period of 4 weeks, a significant increase in MIP (-62.20 ± 25.78 to -81.53 ± 23.09), MEP (73.4 ± 31.95 to 90.33 ± 28.39), and FVC (94.86 ± 16.77 to 98.56 ± 17.44) was observed. Regarding the anthropometric variables, a significant increase was also observed in BMI (20.18 ± 5.04 to 20.40 ± 4.69), arm circumference (23.38 ± 3.28 to 25.08 ± 4.55), arm muscle circumference (21.48 ± 3.00 to 22.07 ± 3.36), and triceps skinfold thickness (5.62 ± 2.68 to 8.33 ± 6.59). Conclusion: Pulmonary and nutritional preparation can improve respiratory muscle strength, FVC and anthropometric parameters. However, further studies are needed to confirm the effectiveness of this preoperative preparation.</p></div

Pulmonary function evaluation in type 2 diabetes mellitus patients submitted to metabolic surgery

<div><p>Abstract Introduction: Diabetes Mellitus (DM) is a multifactorial metabolic disorder. As considered a public health problem needing additional treatment options. Objective: This prospective study aimed at evaluating pulmonary function through spirometry, before and after metabolic surgery without gastric resection in type 2 DM patients. Methods: Sample was composed by 17 type 2 DM females. They were analyzed in pre (24 hours before surgical procedure), immediate post-operative period POST1 (24 hours after surgical procedure) and in the late postoperative period POST2 (two years after surgical procedure). Besides statistical analysis, it was evaluated the following spirometric parameters: forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and the FEV1 / FVC ratio (%). Results: Spirometric parameters showed a value increase when compared PRE and POS2 values, except for FVC and FEV1, which was not statistically significant. Conclusion: Type 2 DM women submitted to metabolic surgery without gastric resection showed spirometric value increased after two-year surgical procedure, when compared to preoperative period values. It is important additional studies about pulmonary function, diabetic patients and metabolic surgery without gastric resection.</p></div
