Employment in Nursing and Preterm Birth: Are They Linked?

The possibility that employment itself, with all its rewards, both intrinsic and monetary, could be harmful to maternal and fetal health is always a matter for concern. When that suggestion is made about an archetypical female form of employment (nursing), and a specialist group devoted to the health care of women and infants, it is deeply alarming. So the recent publication which states, "our results show that strenuous working conditions are an important risk factor for preterm birth among US nurses," has been widely reported and discussed. The study was a case-control study with cases and controls drawn from respondents to a cross-sectional mailed survey of members of the Association of Women's Health, Obstetric and Neonatal Nurses.

Introduction and Aims: Choline-metabolizing genetic variation may interact with choline intake on fetal programming and pregnancy outcome. This case-control study aims to explore the association of maternal choline consumption and phosphatidylethanolamine N-methyltransferase (PEMT) gene polymorphism rs7946 with preterm birth risk. Methods: 145 Han Chinese women with preterm delivery and 157 Han Chinese women with term delivery were recruited in Shanghai. Dietary choline intake during pregnancy was assessed using a validated food frequency questionnaire. Additionally, DNA samples were genotyped for PEMT rs7946 (G5465A) with plasma homocysteine (Hcy) levels measured. Results: Compared with the lowest quartile of choline intake, women within the highest consumption quartile had adjusted odds ratio (aOR) for preterm birth of 0.48 (95% confidence interval, CI [0.24, 0.95]). There was a significant interaction between maternal choline intake and PEMT rs7946 (p for interaction = 0.04), where the AA genotype carriers who consumed the energy-adjusted choline <255.01 mg/day had aOR for preterm birth of 3.75 (95% CI [1.24, 11.35]), compared to those with GG genotype and choline intake >255.01 mg/day during pregnancy. Additionally, the greatest elevated plasma Hcy was found in the cases with AA genotype and choline consumption <255.01 mg/day (p < 0.001). Conclusion: The AA genotype of PEMT rs7946 may be associated with increased preterm birth in these Han Chinese women with low choline intake during pregnancy.

Control Study

Stroke is a major cause of disability worldwide, and balance impairments are common disabling factors in patients with stroke, leading to falls. Thus, the study objectives were as follows: (i) To find the prevalence of balance impairment among patients with stroke. (ii) To find out the factors associated with balance impairment in patients with stroke. This cross-sectional retrospective case control study involved eighty-one post stroke patients with a mean age of 58.36 ± 14.06, recruited from six hospitals, who underwent an assessment of balance, walking speed, depression and isometric strength of the ankle and knee. These patients were later categorized into subjects with good balance (<45) in the Berg balance scale (BBS) and those with poor balance (≥45), as cases and controls, to assess the factors associated with balance impairment using binary logistic regression. The prevalence of balance impairment among patients with stroke was 48.1%. The reduction in power of knee flexors (OR = 0.858), knee extensors (OR = 0.880) and ankle dorsiflexors (OR = 0.820) was found to be significantly associated with balance impairment, along with speed (OR = 1.187 (95% CI = 1.100, 1.280)), depression (OR = 1.331 (95% CI = 1.055–1.679)) and activities of daily living (OR = 0.313 (95% CI = 0.150–0.650)). In summary, around half of the patients with stroke exhibited balance impairments, with females being more prone.
