Objectives More than 10 % of pregnant women in the United States (U.S.) suffer from depression, which has far-reaching consequences on maternal and fetal well-being. There is conflicting evidence regarding the prevalence of antenatal depression among different race and ethnic groups. This systematic review aimed to summarize the existing literature concerning racial/ethnic disparities in the prevalence and correlates of antenatal depression in the U.S. Methods PubMed, CINAHL and PsycINFO databases were searched online for research studies published in English in peer-reviewed journals until March 2015, using a pre-designed search strategy. Eligibility was determined using pre-specified criteria; and quality was assessed. Results Forty-one (41) articles met the criteria; 13 were cross-sectional, and 21 were longitudinal studies. Overall, the prevalence of antenatal depression was 10–30 %; it was higher among non-Hispanic blacks (NHBs) and Hispanics, compared to non-Hispanic whites (NHWs). Few studies looked at the correlates of depression by race/ethnicity. Among employed women, higher depression scores were observed among NHBs, compared to NHWs; while there was no racial difference among unemployed women. Racial difference and race-employment interaction disappeared once discrimination was accounted for. In another study, higher parity, higher stress, and lower self-esteem were significant correlates of depression among NHBs, while less satisfaction with social support, and higher stress predicted higher depression scores among NHWs and Hispanics respectively. Conclusions The findings of our review suggest that not only is antenatal depression a major public health issue that needs to be addressed, but different racial/ethnic groups seem to differ in their vulnerability and risk factors.  相似文献

Background: Direct enteral feeding tube (DET) placement for dysphagia after stroke is associated with poor outcomes. However, the relationship between timing of DET placement and poststroke mortality and disability is unknown. We sought to determine the risk of mortality and severe disability in patients who receive DET at different times after stroke. Methods: We used the Ontario Stroke Registry and linked administrative databases to identify patients with acute ischemic stroke or intracerebral hemorrhage between 2003 and 2013 who received DET (gastrostomy or jejunostomy) during their hospital admission. We grouped patients by week of DET placement and evaluated mortality at 30 days and 6 months after DET insertion, and disability at discharge. We used Cox proportional hazard models and multiple logistic regression to determine the association between time from admission to DET placement and outcomes, adjusting for patient and hospital factors. Results: In the study sample of 1367 patients, the median time from admission to DET placement was 17 days. After adjustment, each week of delay to DET placement was associated with lower mortality at 30 days (adjusted hazard ratio [aHR] .88, 95% confidence interval [CI] .79-.98), but not at 6 months (aHR .98, 95% CI .91- 1.05), and a higher likelihood of severe disability at discharge (adjusted odds ratio 1.35, 95% CI 1.13- 1.60). Conclusions: Later DET placement after stroke was associated with lower 30-day mortality but higher severe disability at discharge. Further research is needed to understand the reasons for these observations and to optimize patient selection and timing of DET.  相似文献

Purpose

Type and volume of fluid administered for intrapartum maintenance had been reported to differently affect labor length, delivery mode, and cord artery pH and glucose level. We aimed to compare the effect of three different fluid regimens on labor duration.

Methods

In a randomized trial, healthy nulliparous in labor were randomized into one of three intravenous fluid regimens: group 1, the reference group, lactated Ringer’s solution infused at a rate of 125 mL/h; group 2, lactated Ringer’s solution infused at a rate of 250 mL/h; group 3, 0.9% saline solution boosted with 5% glucose, infused at a rate of 125 mL/h. The primary outcome was labor length from enrollment until delivery.

Results

Between December 2010 and July 2015, 300 women were randomized to one of the three groups. Demographic and baseline obstetric characteristics were comparable between the groups. There was no significant difference in the time from enrollment to delivery (p = 0.62). Furthermore, there were no significant differences in second stage duration (p = 0.73), mode of delivery (p = 0.21), cord artery pH and glucose level between the groups.

Conclusions

Increasing the intravenous volume of lactated Ringer’s solution or substituting to fluid containing 5% glucose solution does not affect labor length.

This study was designed to compare the efficacy of intraventricular (IV), intramyocardial (IM) or combined IV and IM injections of human adipose tissue-derived stem cells (hADSCs) administered either immediately, 5, or 10 days after induction of acute myocardial infarction (AMI) in a nude rat model. Acute myocardial infarction was induced in 99, adult (250–350 g BW), male nude rats strain Crl:NIH-Fox1RNU. Rats received either no cells (group I, n?=?15) or 2 million, hADSCs as follows: group II (n?=?19) IV injection immediately after AMI; group III (n?=?18) IV injection 5 days after AMI; group IV (n?=?15) IV injection 5 days and IM injection 10 days after AMI; group V (n?=?17) IV injection immediately after AMI and IM injection 10 days after AMI and group VI (n?=?15) IM injection 10 days after AMI. Tissue sections from hearts were studied using H&E and immunohistochemistry. In the control group, there was a tendency toward granulation tissue formation, active phagocytosis, and variable angiogenesis when evaluated at 10 days, early fibrosis when evaluated at 30 days, and established fibrosis when evaluated at 60 days. However, hADSC-treated groups showed a tendency toward cardiomyocyte regeneration and prominent angiogenesis when evaluated at 10 days and smaller infarction size when evaluated at 30 and 60 days. The present study showed a significantly decreased amount of scar tissue following myocardial infarction and enhanced regenerative capacity of myocardial cells following a single, intraventricular injection of 2 million hADSCs immediately after AMI.  相似文献

BACKGROUND: Becker nevus is a hamartoma with brown hyperpigmentation and hypertrichosis that usually affects young males. It has a predilection for the upper half of the trunk and proximal upper extremity. OBJECTIVE: This is a case report of a 38-year-old male with a Becker nevus without hypertrichosis on the lower limb and a review of the literature. RESULTS: Including our case report, 12 cases of Becker nevus on the lower limb were identified in the English literature (8 males and 4 females). It has never been reported below the knee. In males, the lesion was not associated with other anomalies, and all but two showed hypertrichosis (six of eight). In 50% (two of four) of women, it was associated with localized lipoatrophy. In one woman, it presented without hypertrichosis. CONCLUSION: The presence of Becker nevi on the lower limb is unusual, and hypertrichosis is not always a feature. Larger studies are required to look into the true prevalence of this presentation and its prognostic value as a marker for other anomalies.  相似文献
