question:
The aim of this study is to determine the consequences of delayed presentation of anorectal malformations and emphasize the causes of delayed diagnosis of these malformations.', 'We retrospectively reviewed 54 neonatal patients with a diagnosis of anorectal malformations. Group 1 consisted of 35 patients diagnosed within the first 48h of life and Group 2 included 19 patients diagnosed after 48h of life.', 'Obstructive symptoms at the time of diagnosis, overall complications and the mean postoperative hospitalization period in Group 2 were markedly higher than that of Group 1. A comprehensive neonatal examination within the first 48h of life was performed in 32 (91.4%) patients in Group 1 and 5 (26.3%) of the patients in Group 2 (p<0.001).

question:
In heart failure, a holistic approach incorporating the patient's perspective is vital for prognosis and treatment. Self-rated health has strong associations with adverse events and short-term mortality risk, but long-term data are limited. We investigated the predictive value of two consecutive self-rated health assessments with regard to long-term mortality in a large, well characterised sample of elderly patients with stable chronic heart failure.", "We measured self-rated health by asking 'In general, would you say your health is: 1, excellent; 2, very good; 3, good; 4, fair; 5, poor?' twice: at baseline and the end of a 12-week beta-blocker up-titration period in the CIBIS-ELD trial. Mortality was assessed in an observational follow-up after 2-4 years. A total of 720 patients (mean left ventricular ejection fraction 4512%, mean age 735 years, 36% women) rated their health at both time points. During long-term follow-up, 144 patients died (all-cause mortality 20%). Fair/poor self-rated health in at least one of the two reports was associated with increased mortality (hazard ratio 1.42 per level; 95% confidence interval 1.16-1.75; P<0.001). It remained independently significant in multiple Cox regression analysis, adjusted for N-terminal pro B-type natriuretic peptide (NTproBNP), heart rate and other risk prediction covariates. Self-rated health by one level worse was as predictive for mortality as a 1.9-fold increase in NTproBNP.

question:
Halothane exerts a potent negative inotropic effect on the heart and mimics many of the cardiac effects of lowered extracellular CaCl2. Reduced slow inward Ca2+ current and sarcoplasmic reticular effects on intracellular Ca2+ are likely involved. The authors reported previously that halothane protects against hypoxic and ischemia reperfusion injury in isolated hearts. The aim of this isolated heart study was to compare protective effects of halothane and low CaCl2 (0.5 mM) administered during 1 day of hypothermic perfusion on return of normothermic perfusion.', "Guinea pig hearts (n = 66) were isolated and perfused at 37 degrees C with a Krebs' solution, gassed with 96% O2, 4% CO2, and containing 2.5 mM Ca2+, and 4.5 mM K+. Heart rate, isovolumetric left ventricular pressure, coronary flow, %O2 extraction, O2 consumption rate, and relative cardiac efficiency (EFF = heart rate.left ventricular pressure/O2 consumption rate) were measured in five groups of hearts: time controls (no hypothermia); 1.5, and 3% halothane delivered by vaporizer; cold controls (hypothermia only); and 0.5 mM CaCl2. Halothane was administered, or CaCl2 was decreased 0.5 h before hypothermia at 3.8 +/- 0.1 degrees C, during hypothermia for 22 h, and for 0.5 h after rewarming to 37.0 +/- 0.1 degrees C. Hearts were perfused at 25% of initial coronary flow during hypothermia.", 'All groups had similar ventricular function and vasodilator responses before hypothermia. During normothermic reperfusion after hypothermia, both concentrations of halothane protected better than low CaCl2. Values, expressed as a percent of initial values in the five groups (time control, 3% halothane, 1.5% halothane, cold control, and 0.5 mM CaCl2, were respectively: 90 +/- 6, 54 +/- 6*, 48 +/- 5*, 27 +/- 8, 27 +/- 4% for left ventricular pressure; 84 +/- 5, 61 +/- 4*, 62 +/- 6*, 40 +/- 5, 34 +/- 5% for EFF; and 102 +/- 3, 63 +/- 3*, 66 +/- 3*, 55 +/- 2, 42 +/- 2% for coronary flow (*P < 0.05 halothane vs. 0.5 mM CaCl2). The coronary flow response to endothelium-dependent (acetylcholine) and endothelium-independent (nitroprusside) vasodilators was also greater after halothane than after 0.5 mM CaCl2.
