Increasing levels of pharmacologic acid suppression are associated with increased risks of nosocomial C difficile infection. This evidence of a dose-response effect provides further support for the potentially causal nature of iatrogenic acid suppression in the development of nosocomial C difficile infection.

OBJECTIVE-The study evaluates lipids profile changes during gestation in pregnancies with and without preeclampsia and/or gestational diabetes.STUDY DESIGN-Lipid profiles were assessed between year prior and after pregnancy in 9911 women without cardiovascular comorbidities.RESULTS-Lipid levels during gestation varied substantially with a nadir following conception and a peak at delivery. Compared to preconception levels total cholesterol levels increased from 164.4 mg/dL to 238.6 mg/dL and triglycerides (TGs) from 92.6 mg/dL to 238.4 mg/dL. The composite endpoint (gestational diabetes mellitus or preeclampsia) occurred in 1209 women (12.2%). Its prevalence increased with levels of TG-from 7.2% in the group with low TGs (<25th percentile adjusted for the gestational month) to 19.8% in the group with high TGs (>75th percentile), but was not associated with high-density lipoprotein levels. In multivariate analysis higher TGs levels, but not low high-density lipoprotein, were associated with the primary endpoint.CONCLUSION-Lipid levels change substantially during gestation. Abnormal levels of TGs are associated with pregnancy complications. Keywords adverse outcomes; gestation; lipidsA number of diseases affecting the cardiovascular system emerge during pregnancy. Gestational diabetes mellitus is a risk factor for the development of type 2 diabetes and gestational hypertension is associated with an elevated risk for developing subsequent systemic hypertension. 1-3 Gestational diabetes and hypertension can contribute to maternal and fetal risk of developing peri-and postpartum complications. 4,5 Reprints: Victor Novack, MD, PhD,

ObjectivesThe objectives of this study were: 1) To determine the component needed to generate a validated DIC score during pregnancy. 2) To validate such scoring system in the identification of patients with clinical diagnosis of DIC.Material and MethodsThis is a population based retrospective study, including all women who gave birth at the ‘Soroka University Medical Center’ during the study period, and have had blood coagulation tests including complete blood cell count, prothrombin time (PT)(seconds), partial thromboplastin time (aPTT), fibrinogen, and D-dimers. Nomograms for pregnancy were established, and DIC score was constructed based on ROC curve analyses.Results1) maternal plasma fibrinogen concentrations increased during pregnancy; 2) maternal platelet count decreased gradually during gestation; 3) the PT and PTT values did not change with advancing gestation; 4) PT difference had an area under the curve (AUC) of 0.96 (p<0.001), and a PT difference ≥1.55 had an 87% sensitivity and 90% specificity for the diagnosis of DIC; 5) the platelet count had an AUC of 0.87 (p<0.001), an 86% sensitivity and 71% specificity for the diagnosis of DIC; 6) fibrinogen concentrations had an AUC of 0.95 (p<0.001) and a cutoff point ≤3.9 g/L had a sensitivity of 87% and a specificity of 92% for the development of DIC; and 7) The pregnancy adjusted DIC score had an AUC of 0.975 (p<0.001) and at a cutoff point of ≥26 had a sensitivity of 88%, a specificity of 96%, a LR(+) of 22 and a LR(−) of 0.125 for the diagnosis of DIC.ConclusionWe could establish a sensitive and specific pregnancy adjusted DIC score. The positive likelihood ratio of this score suggests that a patient with a score of ≥26 has a high probability to have DIC.

Therapy with statins may be associated with a reduced risk of infection-related mortality. This protective effect is independent of all known comorbidities and dissipates when the medication is discontinued. If this finding is supported by prospective controlled trials, statins may play an important role in the primary prevention of infection-related mortality.
