Infection rate of Schistosoma japonicum in the snail Oncomelania hupensis quadrasi in endemic villages in the Philippines: Need for snail surveillance technique

@#Schistosomiasis japonica is one of seven NTDs endemic in the Philippines that continues to threaten public health in the country. The causative agent, the blood fluke Schistosoma japonicum, uses an amphibious snail Oncomelania hupensis quadrasi which can harbor larval stages that multiply asexually, eventually producing the infective cercariae which are shed into the water. Contamination of freshwater bodies inhabited by the snail intermediate host occurs through release of human and animal feces containing S. japonicum eggs. Miracidia hatching from these eggs subsequently infect the snails that inhabit these water bodies. The degree of fecal contamination can vary across snail sites and influences snail infection rates in these sites. In this study, conventional malacological surveys using intensive manual search for snails were conducted from 2015 to 2016 in seven selected endemic provinces, namely Leyte and Bohol in the Visayas and Surigao del Norte, Agusan del Sur, Bukidnon, Lanao del Norte and Compostela Valley in Mindanao. A total of 6,279 O. hupensis quadrasi snails were collected from 38 snail sites. The municipality of Trento in Agusan del Sur recorded the highest number of snail sites (7) that yielded O. hupensis quadrasi snails while only one snail site was found positive for O. hupensis quadrasi snails in Kapatagan in Lanao del Norte and Talibon in Bohol. Alegria in Surigao del Norte yielded the highest number of snail sites (5) that were found to harbor snails positive for S. japonicum infection. The snail infection rates in this municipality ranged from 0.43% to 14.71%. None of the snails collected from Talibon in Bohol was infected. Bohol is the only province among the 28 schistosomiasis-endemic provinces which has reached near elimination status. Snail infection rates were found to vary considerably across snail sites, which could be due to the degree of fecal contamination of the snail sites and their connectivity to water that can serve as contamination source.

Fatores preditores do alcance das metas de um programa de intervenção em nipo-brasileiros / Predictors of goal achievement in an intervention program among Japanese-Brazilians

Identificar fatores da linha de base preditores do alcance das metas do programa de intervenção no estilo de vida após 12 meses em população de nipo-brasileiros, empregando-se modelos de regressão logística ajustados. Em 2005, 321 participantes eram portadores de excesso de peso e houve maior chance [OR (IC95 por cento)] de alcance da meta de perda de peso após 12 meses entre mulheres [2,45 (1,33; 4,13)], indivíduos de maior idade [1,03 (1,00; 1,06)] e menor chance entre portadores de morbidades no início do estudo [0,33 (0,14; 0,77)]. Dos 261 indivíduos sedentários, o alcance da meta de atividades físicas foi inversamente relacionado ao exercício de atividades profissionais [0,40 (0,17; 0,95)]. Não se verificou fatores da linha de base associados ao alcance das metas do consumo de legumes, verduras e frutas e gorduras saturadas da dieta após 12 meses. Indivíduos de maior idade, mulheres, não portadores de morbidades e sem exercício de atividades profissionais na linha de base apresentaram maior chance de alcance das metas após 12 meses de intervenção no estilo de vida.

The aim of this study was to identify baseline factors associated with achieving goals after a 12-month lifestyle intervention program in a Japanese-Brazilian population, using adjusted logistic regression models. In 2005, 321 participants were overweight. The odds [OR (IC95 percent)] of reaching the goals after 12 months of intervention were directly related to female gender [2.35 (1.34, 4.13)] and older age [1.03 (1.00, 1.06)] and inversely related to baseline morbidity [0.33 (0.14, 0.77)]. Of the 261 sedentary individuals, achieving the goal for physical activity was inversely related to working [0.44 (0.17, 0.95)]. No baseline predictors were found for reaching the goal of fruit and vegetable consumption or saturated fat intake after 12 months. At baseline, women, older individuals, and individuals without diseases or not working showed increased odds of achieving the goals after 12 months of the lifestyle intervention.

Cirurgia reconstrutiva e angioplastia no tratamento de nove doentes portadores de oclusöes crônicas das artérias subclávias / Reconstrutive surgery and percutaneous angioplasty in the tratment of nine patients with chronic subclavian artery occlusion

A proposta deste estudo foi apresentar uma série de pacientes com doença oclusiva da artéria subclávia tratados por procedimento cirúrgico ou angioplastia. Durante um período de cinco anos, nove pacientes com idade média de 54 anos foram submetidos a seis derivaçöes carótidas-subclávias, uma endarterectomia e duas angioplastias. Os resultados clínicos foram inteiramente satisfatórios em quatro pacientes com sintomas cerebrais, em dois com isquemia de membro e em dois dos três com sintomas mistos. Um paciente faleceu e dois foram perdidos para seguimento. As reconstruçöes permaneceram pérvicas em cinco pacientes entre 12 e 28 meses de seguimento de seguimento mas ocluiu em outro. A revascularizaçäo das artérias subclávia é efetiva tanto com procedimentos cirúrgicos como com a angioplastia.

Improvement of cardiac function by short atrioventricular delay and diastolic mitral regurgitation in patients implanted with DDD pacemakers

Efficacy of short atrioventricular (AV) delay and diastolic mitral regurgitation (MR) were studied in 16 patients (70.2 mais ou menos 10.5 SD years old) with implanted DDD pacemakers. AV delay was set at 0.215 and 0.115 sec. In 10 of the 16 patients, diastolic MR was not observed when the AV delay was set at both 0.215 and 0.115 sec. Cardiac output (CO) and pulmonary capilary wedge pressure (PCWP) did not change.In 6 of the 16 patients, diastolic MR was observed when the AV delay was set a 0.215 se However, diastolic MR was not observed when the AV delay was set at 0.115 sec. CO increased from 3.6 mais ou menos 0.7 to 3.9 mais ou menos 0.8 I/min (p menor que 0.05). PCWP was decreased in 5 of the 6 patients (83 por cento, p menor que 0.05 vs. 10 por cento in patients without diastolic MR at 0.215 sec of AV delay). Cardiac function may be improved by shortening AV delay when the diastolic MR was observed. On the other hand, short AV delay may not be effective for patients in whom diastolic MR was ntobserved.
