Role of Hyperleptinemia in the Regulation of Blood Pressure and Cardiac Function To the Editor: We read with great interest the article by Dr Samuelsson et al1 dealing with the relationships between hyperleptinemia and blood pressure or myocardial function. The results of their study demonstrated that exposure to hyperleptinemia in neonatal rats might lead to early onset of hypertension, which ...

BACKGROUND During spinal anesthesia for cesarean delivery, phenylephrine can cause reflexive decreases in maternal heart rate and cardiac output. Norepinephrine has weak β-adrenergic receptor agonist activity in addition to potent α-adrenergic receptor activity and therefore may be suitable for maintaining blood pressure with less negative effects on heart rate and cardiac output compared with ...

background: use of single measurement of risk factors can distort their estimated effects, due to random error in measurements. the aim of this study was to examine the extent of underestimation in the estimated effect of common variables in physical exam i.e. systolic and diastolic blood pressure (sbp, dbp) and body mass index (bmi) on cardiovascular diseases in tehran lipid and glucose study ...

Computerised continuous measurement of mean arterial blood pressure (MAP) and serial cranial ultrasonography in 33 infants of less than 31 weeks' gestation showed that a MAP of less than 30 mm Hg for over an hour was significantly associated with severe haemorrhage, ischaemic cerebral lesions, or death within 48 hours. No severe lesions developed with a MAP greater than or equal to mm Hg.

Ambient air pollution has been associated in some studies (but not all) with increased blood pressure in adults and children. A study in this issue of EHP examines even ea rl ier exposures during gestation, an important period of ca rd iova scu la r growth and development. The results show a small but signif icant increase in newborn systolic blood pressure associated with exposure in the third...

background tracking of blood pressure from early life to adulthood and the increasing prevalence of elevated blood pressure in the pediatric age group are considered as important health issues. rapid lifestyle change and dietary habits are considered as important determinants of this problem. this study aimed to systematically review the studies on the association of dietary habits and blood pr...

this study was conducted to investigate the effects of brewer's yeast supplementation on serum lipoproteins and blood pressure in patients with type 2 diabetes mellitus.in a randomized double blind clinical trial, 90 adults with type 2 diabetes mellitus were recruited, and divided randomly into 2 groups, trial group received brewer's yeast (1800 mg/day) and control group received placebo for 12...

patients and methods in a double-blind clinical trial, 103 patients (american society of anesthesiologists class i, ii) aged 18 - 45 years old, who were septorhinoplasty candidates, were randomly assigned into two groups, a 900 mg gabapentin group and placebo, in amir-al-momenin academic hospital. the drug was prescribed to the patients orally, 2 hours before the operation. anesthetic technique...
