Objetivo: Avaliar a prevalência, a intensidade e o desconforto da sede no período pós-operatório imediato. Método: Estudo epidemiológico, transversal, descritivo, quantitativo, realizado em um hospital universitário do Sul do Brasil, de agosto a setembro de 2012. A amostra foi composta de 386 pacientes em recuperação anestésica de cirurgias eletivas e de urgência. Foi utilizado um questionário semiestruturado composto de dados demográficos, clínicos e variáveis relacionadas à sede. Resultados: A prevalência de sede foi de 78% (303 pacientes), com intensidade média de 6,94 (desvio padrão — DP=2,2) e queixa espontânea de sede em 38,3% dos casos (116 pacientes). Os desconfortos relatados foram: boca seca, procura por água, hipossalivação, garganta seca, lábios ressecados, língua seca e vontade de deglutir. Todos os desconfortos apresentaram correlação de Pearson positiva em relação à presença de sede. Conclusão: A sede no pós-operatório imediato é intensa, prevalente e com sinais periféricos desconfortáveis. Essas evidências fundamentam a necessidade da identificação, da mensuração, da avaliação e do tratamento do sintoma sede de forma intencional neste período

Atrial fibrillation (AF) is prevalent in patients with obesity and diabetes, and such patients often exhibit cardiac steatosis. Since the role of cardiac steatosis per se in the induction of AF has not been elucidated, the present study was designed to explore the relation between cardiac steatosis and AF. Transgenic (Tg) mice with cardiac-specific overexpression of perilipin 2 (PLIN2) were housed in the laboratory for more than 12 mo before the study. Electron microscopy of the atria of PLIN2-Tg mice showed accumulation of small lipid droplets around mitochondrial chains, and five- to ninefold greater atrial triacylglycerol (TAG) content compared with wild-type (WT) mice. Electrocardiography showed significantly longer RR intervals in PLIN2-Tg mice than in WT mice. Transesophageal electrical burst pacing resulted in significantly higher prevalence of sustained (>5 min) AF (69%) in PLIN2-Tg mice than in WT mice (24%), although it was comparable in younger (4-mo-old) mice. Connexin 43 (Cx43), a gap junction protein, was localized at the intercalated disks in WT atria but was heterogeneously distributed on the lateral side of cardiomyocytes in PLIN2-Tg atria. Langendorff-perfused hearts using the optical mapping technique showed slower and heterogeneous impulse propagation in PLIN2-Tg atria compared with WT atria. Cardiac overexpression of hormone-sensitive lipase in PLIN2-Tg mice resulted in atrial TAG depletion and amelioration of AF susceptibility. The results suggest that PLIN2-induced steatosis is associated with Cx43 remodeling, impaired conduction propagation, and higher incidence of AF in aged mice. Therapies targeting cardiac steatosis could be potentially beneficial against AF in patients with obesity or diabetes.

Recent genome-wide association studies have identified multiple variants that confer risk of type 2 diabetes mellitus (DM). However, established associations explain only a part of the heritability. Thus, even at the genome-wide association studies era, candidate gene approach should be still useful. Recent interventional studies against the renin-angiotensin system (RAS) showed reduction in new onset of DM, implying the system is involved in the onset. We substantiated the hypothesis that genetic variants of RAS have significant association with prevalence of DM. We enrolled to the study consecutive 782 subjects who had consulted our hospitals for mainly lifestyle related diseases. They consisted of 282 (36.1 %) diabetes cases. Genotypes were assayed with genomic DNA for conventional four genes of the RAS, i.e., angiotensin converting enzyme (ACE) insertion/deletion variant, angiotensinogen (AGT) M235T variant, angiotensin II type I receptor (AT1) A1166C variant, and aldosterone synthase (CYP11B2) C-344T variant. Association between the genetic variants of the RAS and prevalence of type 2 DM was tested. A significant association of DM and CYP11B2 genotype was obtained. There was no significant association between DM and ACE, AGT and AT1 variants. A multivariate logistic regression showed that age, gender, and CYP11B2 genotype were independent factors for association to diabetes, the DM risk of CC/CT to TT being 1.40 (95 % CI 1.04–1.90, p = 0.029). Thus, it is concluded that a genetic variant of the RAS should have a modest but significant impact on the onset of type 2 diabetes mellitus.

<p>Objetivo: avaliar o tempo de jejum pré-operatório, presença e intensidade da sede no pós-operatório imediato. Método: pesquisa documental, quantitativa, descritiva, realizada em 2018, em hospital escola, com amostra de 749 pacientes. Resultados: o tempo médio de jejum absoluto foi de 15:00 (DP 6:30). Pacientes cirúrgicos da urologia apresentaram maior tempo de jejum (16:56; DP 9:09). Em relação à faixa etária, o tempo de jejum variou de 13:29 (DP 7:34) para crianças, a 15:06 (DP 6:32) em adultos e 15:41 (DP 4:37) em idosos. A sede foi um desconforto presente em 84,5% dos pacientes, com intensidade média de 6,54 (DP 2,39) no pós-operatório. Houve associação significativa entre tempo de jejum e presença de sede.

The plasma renin activity (PRA) is affected by a number of environmental factors. However, significant heritability has been shown for the activity. A hypothesis that a candidate regulatory single-nucleotide polymorphism, C-5312T, of human renin gene should have a significant effect on PRA was elucidated and updating of independent determinants of PRA was attempted.Cross sectional study.Outpatient study.We enrolled consecutive 810 subjects who had consulted our hospitals for lifestyle-related diseases.Genotypes were assayed with genomic DNA for C-5312T. Among the genetic variants, the difference of PRA was evaluated. Monovariate linear regression analysis was performed to test the correlation between PRA and clinical variables. Finally, stepwise multiple regression analysis was performed to evaluate the independent determinants.On comparing 2 genotype groups, CC/CT and T allele homozygote, the geometric means of PRA were 0.778 and 0.941 ng/ml/h, respectively (F = 5.992, P = 0.015). Monovariate linear regression analysis revealed that a number of variables have a significant correlation with the activity, including urinary salt excretion. A stepwise multivariate regression analysis revealed that renin C-5312T variant (TT) is one of the independent determinants of PRA.Thus, for the first time, a human renin gene variant was associated with a significant increase in PRA as a genetic factor and the independent determinants for the activity were updated including genetic factor.

The case of a 9-month-old baby girl who failed to develop normally due to nutritional neglect and secondary immunodeficiency characterized by marked thymic involution is reported. The child died of systemic Pseudomonas aeruginosa (P. aeruginosa) infection manifested in pneumonia, lung abscesses, bacterial endocarditis and ecthyma gangrenosum. At autopsy the child was 64 cm in height (normal for a 4- to 5-month-old child) and 5.1 kg in weight (normal for a 2- to 3-month-old child). Multiple gangrenous ecthymas, consisting of deep ulcers, induration and inflammation, were observed in the skin over the entire body. The lungs showed hemorrhagic pneumonia, multiple lung abscesses, and necrotizing arteritis in the abscesses and surrounding areas. The thymus weighed 2.3 g and showed marked involution. Histological examination showed so-called nutritional thymectomy characterized by severe cortical atrophy and clustering, cystic dilation and amorphous changes of the Hassall's corpuscles. In the heart, dark brown verrucae were present at the attachment sites of the tendinous cords of the papillary muscle in the anterior and posterior cusps of the mitral valve, suggesting infectious endocarditis. Bacteriological examination demonstrated P. aeruginosa in the ecthymas, lung abscesses and blood. As primary immunodeficiency was considered unlikely, immunodeficiency secondary to thymic involution following malnutrition seemed to have led to a fatal systemic infection with P. aeruginosa, whose virulence is generally weak. This suggests a close association of the development of such infection and immunodeficiency with child neglect.

BackgroundThe high heritability of plasma renin activity was confirmed in recent investigations. A variation located near the strong enhancer of the human renin gene (REN), C-5312T, has been shown to have different transcription activity levels depending on its allele: the 5312T allele shows transcription levels that are 45% greater than those of the 5312C allele. The purpose of this study was to confirm the hypothesis that variations in the enhancer region of the REN gene are involved in regulating renal expression of renin.MethodsSixty-four subjects with biopsy-proven renal diseases were included in this study (male/female: 35/29, age 41.9 ± 20.9 years, SBP/DBP 123.1 ± 23.7/73.4 ± 14.8 mmHg, s-Cr 0.93 ± 0.63 mg/dl). A genetic variant of REN, C-5312T, was assayed by PCR-RFLP and the TaqMan method. Total RNAs from a small part of the renal cortex were reverse-transcribed and amplified for REN and GAPDH with a real-time PCR system.ResultsLogarithmically transformed expression values of the relative ratio of REN to GAPDH (10−3) were as follows (mean ± SE): CC (26 cases), 0.016 ± 0.005; CT (33 cases), 0.047 ± 0.021 (p = 0.41 vs. CC); TT (5 cases), 0.198 ± 0.194 (p = 0.011 vs. CC, p < 0.031 vs. CT). Thus, significant differences in REN expression were observed among the genetic variants.ConclusionThe results suggest that variants in the enhancer region of the human renin gene have an effect on the expression levels of renin in renal tissue; this observation is in good accordance with the results of the transcriptional assay.
