Nutrition, exercise, work, and sex in pregnancy

This article focuses on the effect of daily living on pregnancy outcome. Although most patients can continue their everyday activities without any concern about effect on pregnancy outcome, all pregnant patients want and need their physician's advice about all of these areas.     

Pathophysiology of prenatal drug-exposure: in utero, in the newborn, in childhood, and in agencies

Medical communities are documenting an increase in the numbers of infants being born with prenatal drug exposure. Medical, educational, and social agencies are serving large numbers of these infants, toddlers, and their families. These infants and toddlers constitute a population whose short-term and long-term needs have not been adequately identified or addressed in the health, social, emotional, or developmental domains. This article discusses the pathophysiology in prenatal drug exposure and the role of the nurse when providing services to these infants, toddlers, and their families.     

Association between serum ferritin, hemoglobin, iron intake, and diabetes in adults in Jiangsu, China

OBJECTIVE: To investigate the association between iron status, iron intake, and diabetes among Chinese adults. RESEARCH DESIGN AND METHODS: This cross-sectional household survey was carried out in 2002 in Jiangsu Province, China. The sample contained 2,849 men and women aged > or =20 years with a response rate of 89.0%. Iron intake was assessed by food weighing plus consecutive individual 3-day food records. Fasting plasma glucose (FPG), serum ferritin, and hemoglobin were measured. RESULTS: The prevalence of anemia was 18.3% in men and 31.5% in women. Mean hemoglobin and serum ferritin increased across groups with increasing FPG. The prevalence of anemia among women was 15.0% in individuals with FPG >7.0 mmol/l compared with 32.6% in individuals with FPG <5.6 mmol/l. There was a similar, however not significant, trend among men. In women, after adjusting for known risk factors, the odds ratio (OR) of diabetes was 2.15 (95% CI 1.03-4.51) for subjects in the upper quartile of hemoglobin compared with the rest, and the corresponding OR for the upper quartile of serum ferritin was 3.79 (1.72-8.36). Iron intake was positively associated with diabetes in women; fourth quartile intake of iron yielded an OR of 5.53 (1.47-20.44) compared with the first quartile in the multivariate analyses. In men, similar trends were suggested, although they were not statistically significant. CONCLUSIONS: Iron status and iron intake was independently associated with risk of diabetes in Chinese women but not in men.     

Brotizolam, a triazolothienodiazepine, in insomnia

Sixty-three outpatients with chronic insomnia were treated for 3 weeks under double-blind conditions with either brotizolam (n = 29) at a dose of 0.25 mg or 0.5 mg or placebo (n = 34). A 3-day placebo period preceded and followed the double-blind treatment phase. Brotizolam consistently produced significantly more sleep improvement than placebo but also more adverse effects. In those patients switched abruptly from brotizolam to placebo, rebound insomnia was observed, being most marked at the first post-brotizolam placebo night.     

Peak expiratory flow in healthy,young, non-active subjects in seated,supine, and prone postures

Objective: To compare the PEFs in healthy, young, non-active subjects in seated, supine, and prone postures. Methods: A total of 30 healthy volunteers (15 male, mean age 22.7 years, non-smokers, sedentary) underwent a physical examination, spirometry to confirm normal pulmonary function, and PEF using the Mini-Wright Peak Flow Meter while wearing a nose clip. PEF measurements were repeated three times in each of three positions (seated, prone, and supine) in random order and differed by less than 20 L/min for a given position. Paired Student’s t-tests were used to analyze the results, and the significance level was set at 5%. Results: The PEF values obtained when the study participants were in a seated position (481.0 ± 115.1 L/min) were higher than those obtained when participants were in prone (453.7 ± 112.1 L/min) or supine (453.2 ± 114.3 L/min) positions (p < 0.05). No significant difference in PEF values was observed between the prone and supine positions. Conclusion: Body posture affects PEF in healthy, young, non-active subjects. PEFs are higher when subjects are in a seated position compared to prone or supine positions, but no difference in PEF is observed between the prone and supine positions.
