Chronic stress may accelerate cellular aging. Telomeres, protective “caps” at the end of chromosomes, modulate cellular aging and may be good biomarkers for the effects of chronic stress, including that associated with acculturation. The purpose of this analysis was to examine telomere length (TL) in acculturating Hispanic Mexican American women and to determine the associations among TL, acculturation, and psychological factors. As part of a larger cross-sectional study of 516 pregnant Hispanic Mexican American women, we analyzed DNA in blood samples (N = 56) collected at 22–24 weeks gestation for TL as an exploratory measure using monochrome multiplex quantitative telomere polymerase chain reaction (PCR). We measured acculturation with the Acculturation Rating Scale for Mexican Americans, depression with the Beck Depression Inventory, discrimination with the Experiences of Discrimination Scale, and stress with the Perceived Stress Scale. TL was negatively moderately correlated with two variables of acculturation: Anglo orientation and greater acculturation-level scores. We combined these scores for a latent variable, acculturation, and we combined depression, stress, and discrimination scores in another latent variable, “negative affectivity.” Acculturation and negative affectivity were bidirectionally correlated. Acculturation significantly negatively predicted TL. Using structural equation modeling, we found the model had an excellent fit with the root mean square error of approximation estimate = .0001, comparative fit index = 1.0, Tucker–Lewis index = 1.0, and standardized root mean square residual = .05. The negative effects of acculturation on the health of Hispanic women have been previously demonstrated. Findings from this analysis suggest a link between acculturation and TL, which may indicate accelerated cellular aging associated with overall poor health outcomes. [ABSTRACT FROM AUTHOR]

Aims The aims of this study are to describe: (1) the frequency of nurse-reported missed care in neonatal intensive care units; and (2) nurses' reports of factors contributing to missed care on their last shift worked. Background Missed nursing care, or necessary care that is not delivered, is increasingly cited as a contributor to adverse patient outcomes. Previous studies highlight the frequency of missed nursing care in adult settings; the occurrence of missed nursing care in neonatal intensive care units is unknown. Design A descriptive analysis of neonatal nurses' self-reports of missed care using data collected through a cross-sectional web-based survey. Methods A random sample of certified neonatal intensive care nurses in seven states was invited to participate in the survey in April 2012. Data were collected from nurses who provide direct patient care in a neonatal intensive care unit ( n = 230). Descriptive statistics constituted the primary analytic approach. Results Nurses reported missing a range of patient care activities on their last shift worked. Nurses most frequently missed rounds, oral care for ventilated infants, educating and involving parents in care and oral feedings. Hand hygiene, safety and physical assessment and medication administration were missed least often. The most common reasons for missed care included frequent interruptions, urgent patient situations and an unexpected rise in patient volume and/or acuity on the unit. Conclusion We find that basic nursing care in the neonatal intensive care unit is missed and that system factors may contribute to missed care in this setting. [ABSTRACT FROM AUTHOR]

We examined the effects of acculturation, depressive symptoms, progesterone, and estriol (E3) as predictors of preterm birth (PTB) in pregnant Hispanic women. This cross-sectional study recruited a sample of 470 Hispanic women between 22- and 24-week gestation from physician practices and community clinics. We used the CES-D to measure maternal depressive symptoms. We measured acculturation by English proficiency on the Bidimensional Acculturation Scale, residence index by years in the USA minus age, nativity, and generational status. Serum progesterone and E3 were analyzed by EIA. Ultrasound and medical records determined gestational age after delivery. In χ analysis, there were a significantly greater percentage of women with higher depressive scores if they were born in the USA. In a structural equation model (SEM), acculturation (English proficiency, residence index, and generational status) predicted the estriol/progesterone ratio (E/P), and the interaction of depressive symptoms with the E/P ratio predicted PTB. Undiagnosed depressive symptoms during pregnancy may have biological consequences increasing the risk for PTB. [ABSTRACT FROM AUTHOR]

Introduction: There is evidence that Mexican Americans are more likely to have cesarean birth than non-Hispanic White Americans. The purpose of this study was to identify factors related to acculturation along with psychological and sociodemographic factors associated with birth mode in a prospective cohort of Mexican American women in Texas. Methods: This secondary analysis included 244 Mexican American pregnant women. Women with a prior cesarean birth were excluded. Variable selection was guided by Berry's Theoretical Framework of Acculturation. Correlations and logistic regression were used to examine relationships and predict risk of cesarean birth. Mediators and moderators were also considered. Results: Eighty women birthed by cesarean. Analytic and parent samples were similar in all demographics. After controlling for parity in logistic regression, greater Spanish language-related acculturative stress (adjusted odds ratio [AOR], 1.06, 95% confidence interval [CI] [1.01, 1.11], p  = .028) and experience of discrimination (AOR, 1.18, 95% CI [1.00, 1.38], p  = .044) increased the odds of cesarean birth. The relationship between acculturative stress and birth mode was moderated by birth facility. Conclusion: Acculturative stress and discrimination may play a role in birth mode for Mexican American women birthing in Texas. Birth facility and acculturative stress may be interacting in ways that have clinical significance but are yet unexplored., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
