The increased severity of acute pancreatitis in the elderly is mainly related to intestinal barrier dysfunction

Impact of the use of Non-Caloric Sweeteners on the Development and Acceptibility of Sweet Preparations

The aim of this study was to substitute saccharose in culinary preparations—custard-filled profiteroles with chocolate topping, chocolate brownie, chocolate mousse, soft coconut candy, soft chocolate fudge, and diet condensed milk—using two types of sweetener, while observing the behavior and performance of these substances, highlighting the difficulties and other required modifications to ensure the acceptance of the final product. Recipes that produced satisfactory characteristics were analyzed by the affective acceptance test using the nine-point hedonic scale to rate specifics attributes. Preparations attaining 50% of scores greater than or equal to 7 were considered accepted. The preference test (Friedman) was applied to products in which both non-caloric sweeteners yielded satisfactory results. Results were analyzed using ANOVA and Tukey tests. The main differences observed in the modified recipes were reduced viscosity, lower yield, less creaminess, less rising, limited capacity to incorporate air, and lower intensity of color and sweetness. Nevertheless, these characteristics did not affect the acceptance of the preparations since the majority of preparations were well accepted by the tasters. No statistically significant difference in preference was detected. The substitution of saccharose by non-caloric sweeteners resulted in products with good acceptability.     

Case Report and Cohort Analysis of Drug-Induced Liver Injury Associated with Daptomycin

A patient receiving daptomycin developed asymptomatic transaminitis and hyperbilirubinemia without concurrent multiorgan dysfunction or elevation of his creatinine kinase level. After ruling out other etiologies, the liver injury was attributed to daptomycin and was subsequently resolved. A single-center retrospective cohort analysis of baseline and follow-up liver function panels (n = 614) from all admissions from 2008 to 2013 during which daptomycin was administered did not reveal any other cases of probable or definite drug-induced liver injury associated with daptomycin.     

Epidemiology and Control of Child Toxocariasis in the Western Brazilian Amazon – A Population-Based Study

Toxocara spp. infection and the seroconversion rate in the Amazon have been poorly investigated. This study analyzed individual and household-level risk factors for the presence of IgG antibodies to Toxocara spp. in urban Amazonian children over a period of 7 years and evaluated the seroconversion rates over a 1-year follow-up. In children < 59 months of age, the overall prevalence rate was 28.08% in 2003 and 23.35% in 2010. The 2010–2011 seroconversion rates were 13.90% for children 6–59 months of age and 12.30% for children 84–143 months of age. Multilevel logistic regression analysis identified child age, previous wheezing, and current infection with hookworm as significant associated factors for Toxocara spp. seropositivity in 2003. In 2010, age, previous helminthiasis, and having a dog were associated with seropositivity, whereas having piped water inside the household was a protective factor. Control programs mainly need to target at-risk children, water quality control, and animal deworming strategies.     

Combined Multichannel Intraluminal Impedance-pH (MII-pH): Multicenter Report of Normal Values from 117 Children

Pancreatic cancer is the fourth leading cause of cancer deaths in the USA. Although some patients will present with premalignant pancreatic lesions (i.e., intraductal papillary mucinous neoplasms) or localized tumors amenable to curative resection, the majority of patients will unfortunately present with technically unresectable or metastatic disease. This review of the recent medical literature will discuss the optimal work-up and management of premalignant pancreatic lesions and the surgical management of localized, borderline resectable, and locally advanced (i.e., unresectable) pancreatic tumors. It will focus on new criteria used to define surgical “resectability,” the significance and clinical impact of surgical margins, the role of multimodality therapy in the management of patients with borderline resectable or locally advanced tumors, the role of surgery for local or distant recurrence, and minimally invasive surgical approaches.     

Comparative analysis of preemptive analgesic effect of tramadol chlorhydrate and nimesulide following third molar surgery

The aim of this prospective, randomized, controlled, paired trial was to perform a comparative analysis of the preemptive analgesic effect of nimesulide and tramadol chlorhydrate during third molar surgery. The study was carried out between March and November 2009, involving 94 operations in 47 male and female patients with bilateral impacted lower third molars in comparable positions. The sample was divided into two groups. Group A received an oral dose of 100 mg of nimesulide 1 h prior to surgery. Group B received an oral dose of 100 mg of tramadol chlorhydrate 1 h prior to surgery. The following aspects were evaluated in the postoperative period: adverse effects of the drugs; amount of rescue medication used (acetaminophen 750 mg); and pain 5, 6, 24, 36, 48, 60, 72 and 84 h after surgery using a visual analog pain scale. Peak pain occurred 5 h after surgery in both groups, with a mean pain score of 2.3 in Group A and 3.0 in Group B; this difference did not achieve statistical significance (p > 0.141). Based on the sample studied, nimesulide and tramadol chlorhydrate demonstrate similar preemptive analgesic effects when used in lower third molar surgeries.
