Question: Extracorporeal membrane oxygenation (ECMO) support is often required in the management of perioperative congenital heart surgery (CHS) patients. However, 24-hour in-hospital congenital cardiac surgical coverage (24-CCSC) is not available at all institutions. The purpose of this study is to evaluate the effect of 24-CCSC on perioperative ECMO outcomes in CHS patients.', "An institutional review board approved, retrospective review of 128 perioperative CHS ECMO patients at a single, quaternary care children's hospital between January 2003 and December 2012 was performed. Primary endpoints evaluated were mortality in children supported with ECMO after undergoing cardiac surgery and ECMO-related morbidity after initiation of 24-CCSC with advanced congenital cardiac surgical fellows. Patients were divided into 2 groups based on whether 24-CCSC was absent (cohort 1: January 2003 to July 2007) or present (cohort 2: August 2007 to December 2012) at the time of ECMO management.", 'The surgical procedures performed were similar in both cohorts based on STAT Mortality Categories (5 Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery Congenital Heart Surgery Mortality Categories). The overall mortality rate in children supported with ECMO after undergoing cardiac surgery was 53%. This mortality was significantly reduced from 68% to 43% (p\xa0= 0.007) with\xa024-CCSC. Multivariate logistic regression analysis revealed that 24-CCSC (p\xa0= 0.009) and lower STAT Mortality Category (p\xa0= 0.042) were independent predictors of operative survival. Cardiac arrhythmias (36% to 16%; p\xa0= 0.012) and pulmonary complications (32% to 8%; p < 0.001) were significantly reduced with 24-CCSC.

Answer: Does twenty-four hour in-hospital congenital cardiac surgical coverage improve perioperative ECMO support outcomes?


Question: It is common in public health and epidemiology that the outcome of interest is counts of events occurrence. Analysing these data using classical linear models is mostly inappropriate, even after transformation of outcome variables due to overdispersion. Zero-adjusted mixture count models such as zero-inflated and hurdle count models are applied to count data when over-dispersion and excess zeros exist. Main objective of the current paper is to apply such models to analyse risk factors associated with human helminths (S. haematobium) particularly in a case where there's a high proportion of zero counts.", 'The data were collected during a community-based randomised control trial assessing the impact of mass drug administration (MDA) with praziquantel in Malawi, and a school-based cross sectional epidemiology survey in Zambia. Count data models including traditional (Poisson and negative binomial) models, zero modified models (zero inflated Poisson and zero inflated negative binomial) and hurdle models (Poisson logit hurdle and negative binomial logit hurdle) were fitted and compared.', 'Using Akaike information criteria (AIC), the negative binomial logit hurdle (NBLH) and zero inflated negative binomial (ZINB) showed best performance in both datasets. With regards to zero count capturing, these models performed better than other models.

Answer: Do zero adjusted models with applications to analysing helminths count data?


Question: To determine whether burn-induced peroxynitrite production and expression of lung inducible nitric oxide synthase (iNOS), intercellular adhesion molecule (ICAM)-1, vascular cell adhesion molecule (VCAM)-1, CXCR2, macrophage inflammatory protein (MIP)-2, and neutrophil chemokine (KC) are mediated by the c-Jun NH2-terminal kinase (JNK).', 'Prospective, experimental study.', 'Research laboratory at a university hospital.', 'Thermal injury models in the mice.', 'In experiment 1, specific pathogen-free C57/BL6 mice were subjected to 30% total body surface area third-degree burn over shaved back. At 0 hr, 2 hrs, 4 hrs, and 6 hrs after burn, lung tissues of those mice were harvested for JNK activity assay, AP-1 DNA-binding activity, and pJNK immunohistochemistry. In experiment 2, a specific JNK inhibitor, SP600125, was given (30 mg/kg intraperitoneally) to mice immediately postburn to suppress the JNK activity. At 8 hrs after burn, blood was assayed for the peroxynitrite-mediated dihydrorhodamine (DHR) 123 oxidation. Lung tissues were harvested for myeloperoxidase (MPO) determination, ICAM-1, VCAM-1, CXCR2, KC, MIP-2, interleukin-1beta, and interleukin-6 messenger RNA expression; iNOS immunohistochemical staining; and histologic studies. Pulmonary microvascular dysfunction was quantified by measuring the extravasations of Evans blue dye.', 'The JNK activity and AP-1 DNA-binding activity of lung tissue significantly increased to a peak at 2 hrs and 4 hrs, respectively, after thermal injury. Immunohistochemical study demonstrated that the increase of the pJNK was mostly from the bronchiole epithelial cells. This increase of MPO activity in lung, blood DHR 123 oxidation level, and lung permeability increased six-fold, nine-fold, and four-fold after burn. SP600125 administration obliterated the thermal injury-induced JNK activity, AP-1 DNA-binding activity, and iNOS expression in lung tissue. SP600125 treatment also significantly decreased MPO activity, blood DHR 123 oxidation, and lung permeability by 54%, 8%, and 47%, respectively, and markedly decreased the thermal injury-induced perivascular and interstitial inflammatory cell infiltration and septum edema. Furthermore, SP600125 abolished thermal injury-induced ICAM-1, VCAM-1, CXCR2, MIP-2, and KC but not interleukin-1beta and interleukin-6 messenger RNA levels of lung tissues.

Answer:
Do thermal injury-induced peroxynitrite production and pulmonary inducible nitric oxide synthase expression depend on JNK/AP-1 signaling?
