introduction: controversial results have been reported about the effect of morphine and stress on learning and spatial memory in rodents. there are very few studies about the effects of ultra low doses of morphine on memory. in this study, effects of acute administration of low and usual doses of morphine on memory formation and retention in the presence and absence of repeated stress were in...
Prevention of pre-eclampsia by low-molecular-weight heparin in addition to aspirin: a meta-analysis.
OBJECTIVE To estimate the impact of adding low-molecular-weight heparin (LMWH) or unfractionated heparin to low-dose aspirin started ≤ 16 weeks' gestation on the prevalence of pre-eclampsia (PE) and the delivery of a small-for-gestational-age (SGA) neonate. METHODS A systematic review and meta-analysis of randomized controlled trials (RCTs) was performed by searching the medical databases Pub...
AIMS To assess the tolerability of initiating/uptitrating sacubitril/valsartan (LCZ696) from 50 to 200 mg twice daily (target dose) over 3 and 6 weeks in heart failure (HF) patients (ejection fraction ≤35%). METHODS AND RESULTS A 5-day open-label run-in (sacubitril/valsartan 50 mg twice daily) preceded an 11-week, double-blind, randomization period [100 mg twice daily for 2 weeks followed by ...
OBJECTIVE To estimate the effect of low-dose aspirin started in early pregnancy on the incidence of preeclampsia and intrauterine growth restriction (IUGR). DATA SOURCES A systematic review and meta-analysis were performed through electronic database searches (PubMed, Cochrane, Embase). METHODS OF STUDY SELECTION Randomized controlled trials of pregnant women at risk of preeclampsia who wer...
Background: Over the past few years, the rapid use of high frequency electromagnetic fields like mobile phones has raised global concerns about the negative health effects of its use. Adaptive response is the ability of a cell or tissue to better resist stress damage by prior exposure to a lesser amount of stress. This study aimed to assess whether radiofrequency radiation can induce adaptive r...
BACKGROUND Pre-eclampsia is a major cause of mortality and morbidity during pregnancy and childbirth. Antiplatelet agents, especially low-dose aspirin, might prevent or delay pre-eclampsia, and thereby improve outcome. Our aim was to assess the use of antiplatelet agents for the primary prevention of pre-eclampsia, and to explore which women are likely to benefit most. METHODS We did a meta-a...
OBJECTIVE Our aim was to test the hypothesis that acetylsalicylate (aspirin) treatment reduces the incidence or severity of pregnancy-associated hypertension. STUDY DESIGN Patients were nulliparous, healthy, and with a singleton gestation at between 20 and 22 weeks' gestation. A sample size of 600 patients was calculated on the basis of p < or = 0.05 and 90% power of observation. A 2-week pla...
BACKGROUND Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality. PURPOSE To systematically review benefits and harms of low-dose aspirin for preventing morbidity and mortality from preeclampsia. DATA SOURCES MEDLINE, Database of Abstracts of Reviews of Effects, PubMed, and Cochrane Central Register of Controlled Trials (January 2006 to June 2013); previous syste...
