Diabetic retinopathy (DR) is the leading cause of blindness in the working-age population, and it increases in severity during pregnancy.Systematic review of literature from PubMed, Cochrane Library and Web of Science using keywords 'diabetic retinopathy' and 'pregnancy' and 'progression' from inception to 2021 was completed. Included studies were (1) peer-reviewed observational studies addressing progression/development of DR in pregnancy, (2) provided the number of diabetic patients that developed/progressed in DR during pregnancy, and (3) included differential data on variables between progression and non-progression groups. This was applied by two independent researchers and referred to a third researcher as necessary. Twenty-seven of the original 138 studies met this criterion. Data were pooled and analysed using fixed-effects in meta-analysis.From 27 studies, 2537 patients were included. Pre-eclampsia [Risk Ratio (RR) 2.62 (95% CI = 1.72, 4.00)] and hypertension treatment during pregnancy [RR 2.74 (95% CI = 1.72, 4.00)] were significantly associated with the development/progression of DR. HbA1c at baseline [MD 0.82 (95% CI = 0.59, 1.06)], duration of diabetes [mean difference (MD) 5.97 (95% CI = 5.38, 6.57)], and diastolic blood pressure at baseline [MD 3.29 (95% CI = 0.46, 6.12)] were all significantly higher in the progression group while only mean birth weight [MD -0.17 (95% CI = -0.31, -0.03)] was significantly higher in the non-progression group.This study fills a gap in the literature and provide physicians with more information on the risk factors associated with the progression of DR in pregnancy and how to counsel this vulnerable patient population appropriately.

Background and objective Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) are rapidly emerging worldwide. This study aimed to assess the effect of contact precaution (CP) on ESBL-PE-colonization rates among nurses in three hospitals in Beirut, Lebanon, where ESBL is endemic, in order to define the risk factors for colonization. Accordingly, the ongoing use of CP to prevent ESBL-PE transmission to healthy nurses was evaluated. Methods This cross-sectional study was conducted in three hospitals. Hospital 1 required CP, Hospital 2 had recently stopped CP, and Hospital 3 had stopped it three years previously. Questionnaires and stool-collection containers were distributed to all patient care nurses in those three hospitals. The Returned samples were tested using the agar dilution technique. Results A total of 269 out of 733 nurses volunteered to participate; 140 met the inclusion criteria (no recent hospitalization, antibiotic use, or known ESBL-PE colonization) and provided samples. Among them, 15% were ESBL-positive. Compared to nurses from Hospital 3, nurses from Hospital 1 were 59% less likely to be colonized, while nurses from Hospital 2 were 62% more likely to be colonized. Conclusion In hospitals where CP is in place for ESBL-positive patients, ESBL-PE prevalence in nursing staff was significantly lower. Additionally, a work experience of two to four years increased the odds of ESBL-PE colonization in comparison with longer nursing experience. CP may be a justifiable means of protection against ESBL-PE transmission to healthy nurses. The risk factors for colonization were discontinuation of CP and a shorter clinical work experience.

Objective Fetuses measuring below the 10th percentile for gestational age may be either constitutionally small for gestational age (SGA) or have pathologic fetal growth restriction (FGR). FGR is associated with adverse outcomes; however, identification of low-risk SGA cases is difficult. We performed a pilot study evaluating maternal markers of pathologic FGR, hypothesizing there are distinct amino acid signatures that might be used for diagnosis and development of new interventions. Study Design This was a cohort study of healthy women with sonographic fetal estimated fetal weight Results Among 14 women included, five had abnormal UmA, and three had abnormal UtA Doppler results. Those with abnormal UmA showed elevated ornithine. Those with abnormal UtA had lower dimethylglycine, isoleucine, methionine, phenylalanine, and 1-methylhistidine. Conclusion We found several amino acids that might identify pregnancies affected by pathologic FGR. These findings support the feasibility of future larger studies to identify maternal metabolic approaches to accurately stratify risk for small fetuses.

Background: The role of vitamin D in population subgroups throughout the world continues to be a topic of interest among researchers. Current evidence demonstrates that treating vitamin D deficiency plays a significant role in improving mortality in hospitalized patients, reducing hospital length of stay, and boosting innate immune system. Vitamin D levels vary with age, gender, body mass index (BMI) and geographical area. The purpose of this study is to evaluate vitamin D levels in a cohort of patients in Northeast Tennessee. Study: This institutional review board-approved, retrospective study evaluated vitamin D levels of patients obtained from Mcleod Cancer and Blood Center. Vitamin D levels were collected over a 2-year period and classified as deficient (30 ng/mL). Data were then stratified based on patient characteristics (age, gender, body mass index (BMI), race, seasons, and place of residence) and compounds of vitamin D (D2 and D3). Results: There were 2011 individuals included, with only 44.3% having replete levels and 21.4% with levels less than 20 ng/mL. Females with vitamin D deficiency are more likely to have levels below 20 ng/ml compared to males (18.6% vs. 23%, respectively, p = 0.003). Regarding BMI, the highest levels were reported in normal weight and overweight. With regards to age, advanced age (≥70) was associated with the highest levels and most replete patients. Winter months were associated with the lowest levels of vitamin D. Higher vitamin D levels were found in individuals over 70 years, normal weight and overweight category. Conclusion: Testing vitamin D levels in high-risk groups becomes of utmost importance in areas with longer winter months, obese and underweight patients. Vitamin D levels should be routinely tested and treated in vulnerable populations.

Research on in utero opioid exposure impacts has focused on Neonatal Opioid Withdrawal Syndrome (NOWS). However, possible impacts on fetal growth and newborn wellbeing have emerged, with inconsistencies likely driven by methodological issues. Our goal was to compare birth outcomes between newborns with prenatal opioid exposure and a matched control group.Participants were identifiedCompared to biochemically verified controls, exposed newborns had higher rates of fetal growth restriction, weighed less, had decreased length and head circumference, and had higher rates of respiratory distress, sepsis, and jaundice. No significant differences in gestational length, Apgar scores, or neonatal hypoglycemia were found. Adjusted regression analyses revealed that compared to controls, those exposed had an average 150 g decrease in birth weight, a two-fold increased risk for IUGR (OR = 2.09), a nearly three-fold (OR = 2.80) increased risk for jaundice, a more than seven-fold (OR = 7.40) increased risk for respiratory distress, and a thirty-fold (OR = 30.47) increased risk for sepsis.Results suggest significant pregnancy and newborn outcomes beyond NOWS following pregnancy opioid use, informing clinical screening and treatment decisions to enhance health and wellbeing in pregnancy, during the neonatal period, and beyond.

The specific relationship between sexual coercion, intimate partner violence (IPV) during pregnancy, and intimate partner homicide (IPH) is poorly understood. Through a scoping literature review, we identified 101 studies on sexual coercion, IPV during pregnancy, and IPH and created a conceptual model suggesting unintended pregnancies may serve as both a risk factor for and a product of IPV that may escalate to IPH. We illustrate a healthcare systems intervention implication of this model in the context of the Colorado Family Planning Initiative (CFPI). Descriptive statistics suggest an inverse association between contraception access and IPH, which declined by 62% during the first 4 years of the CFPI. Interventions aimed at improving reproductive agency, including improving contraception access and reducing unintended pregnancy, may be a useful opportunity for clinician and health systems to contribute to reducing both lethal and nonlethal IPV.

To examine associations between in utero marijuana exposure and birth outcomes.In two separate cohorts (Appalachian, Rocky Mountain), data were collected from medical records. Marijuana exposure was positive based on urine drug screening at delivery, with nonexposed controls matched on multiple factors including other substance exposure.Marijuana-exposed newborns (n = 531) had significantly worse birth outcomes than controls (n = 531), weighing 218 g less, 82%, 79%, and 43% more likely to be low birth weight, preterm, or admitted to the NICU, respectively, and significantly lower Apgar scores.Marijuana exposure in utero predicted newborn factors linked to longer-term health and development issues. Effects were not attributable to other comorbidities in this study due to rigorous matching and biochemical verification of marijuana and other drug use. Findings add to growing evidence linking marijuana exposure to adverse birth and longer-term outcomes. Women should be encouraged to avoid marijuana use during pregnancy.

OBJECTIVES: Colorado’s relatively high altitudes have been reported to lower birth weight but the most recent studies were conducted 20 years ago. Since then, the accuracy for assigning altitude of residence has been improved with the use of geocoding, and recommendations for pregnancy weight gain have changed. We therefore sought to determine whether currently, residence at high altitude (≥ 2500 m, 8250 ft) lowers birth weight in Colorado. METHODS: Birth certificate data for all live births (n = 670,017) to Colorado residents from 2007 to 2016 were obtained from the Colorado Department of Public Health and Environment. Geocoded altitude of maternal residence for the current birth was assigned to each birth record. Linear and logistic regression models were used to examine the effects of altitude on birth weight or low birth weight (< 2500 g) while controlling for other factors affecting birth weight, including pregnancy weight gain. RESULTS: Compared to low altitude, infants born at high altitude weighed 118 g less and were more often low birth weight (8.8% vs. 11.7%, p < 0.05). After accounting for other factors influencing birth weight, high altitude reduced birth weight by 101 g and increased the risk of low birth weight by 27%. The only factors with larger impacts on birth weight were hypertensive disorders of pregnancy and cigarette use during pregnancy. CONCLUSIONS FOR PRACTICE: High altitude remains an important determinant of elevated LBW rates in Colorado, and likely contributes to Colorado’s comparative resistance towards meeting the Healthy People 2010/2020 nationwide goal to reduce the low birth weight rate to 7.2% by 2020.

Introduction Psychosocial well-being variables from the Tennessee Intervention for Pregnant Smokers (TIPS) study, a longitudinal smoking cessation study in South-Central Appalachia, were investigated as potential predictors of smoking status. Methods A sample of 1031 pregnant women participated in an expanded 5A's (Ask, Advise, Assess, Assist, Arrange) program, from 2008 to 2011. Measures of stress, self-esteem, depressive symptoms, and disordered eating collected by interview during the first trimester, or during the third trimester in a combined interview if participants began prenatal care late, were hypothesized to differ among three groups of participants: pregnant women who never smoked, pregnant women who smoked but quit prior to birth, and pregnant women who smoked and did not quit prior to birth. Smoking status was measured throughout the study. Whether or not a participant quit smoking was assessed at delivery. Results Non-smokers were lowest in stress F(2,1027) = 46.38, p, Highlights • Low stress and high self-esteem predicted smoking cessation in pregnancy. • Disordered eating did not predict smoking cessation in pregnancy. • Depressive symptoms were highest in pregnant smokers who did not quit smoking. • Non-smokers had higher psychosocial well-being scores than smokers and quitters.

Purpose The purpose of this study was to determine if patient characteristics or clinical variables could predict who benefits from individual auditory training. Method A retrospective series of analyses were performed using a data set from a large, multisite, randomized controlled clinical trial that compared the treatment effects of at-home auditory training programs in bilateral hearing aid users. The treatment arms were (a) use of the 20-day computerized Listening and Communication Enhancement program, (b) use of the 10-day digital versatile disc Listening and Communication Enhancement program, (c) use of a placebo “books-on-tape” training, and (d) educational counseling (active control). Multiple linear regression models using data from 263 participants were conducted to determine if patient and clinical variables predicted short-term improvement on word-recognition-in-noise abilities, self-reported hearing handicap, and self-reported hearing problems. Results Baseline performance significantly predicted performance on each variable, explaining 11%–17% of the variance in improvement. The treatment arm failed to emerge as a significant predictor with other clinical variables explaining less than 9% of the variance. Conclusion These results suggest that hearing aid users who have poorer aided word-recognition-in-noise scores and greater residual activity limitations and participation restrictions will show the largest improvement in these areas.

Objective: Social support and religious commitment were examined in relation to antenatal and postpartum depressive symptoms in a prospective, longitudinal study to determine whether religious commitment explained variance in depression scores beyond that accounted for by social support. Background: Social support and religiosity are positively related to good mental/physical health, and depression is related to poor health outcomes in pregnancy and postpartum. It was hypothesised that social support and religious commitment would be inversely related to depressive symptoms, and that religious commitment would predict variance in depression scores over and above social support. Methods: In 106 mostly low SES Appalachian pregnant women, social support and religious commitment were measured during the first trimester. First and third trimester (Center for Epidemiological Studies Depression Scale – 10 item version), and 6 weeks and 6 months postpartum (Edinburgh Postnatal Depression Scale) depression...

There are no data on midwives’ knowledge and management of obstetric anal sphincter injuries (OASIs) in the USA. We performed a cross-sectional national survey characterizing OASI practice by certified nurse midwives (CNMs), hypothesizing that few midwives personally repair OASIs and that there are gaps in CNM OASI training/education. We emailed a REDCap internet-based survey to 6909 American College of Nurse Midwives members (ACNM). We analyzed responses from active clinicians performing at least one delivery per month, asking about OASI risks, prevention, repair, and management. We summarized descriptive data then evaluated OASI knowledge by patient and provider characteristics. We received 1070 (15.5%) completed surveys, and 832 (77.8%) met the inclusion/exclusion criteria. Participants were similar to ACNM membership. Respondents most frequently identified prior OASI (87%) and nutrition (71%) as antepartum OASI risk factors and, less frequently, nulliparity (36%) and race (22%). Identified intrapartum risks included forceps delivery (94%) and midline episiotomy (88%). When obstetric laceration is suspected, 13.6% of respondents perform a rectal examination routinely. Only 15% of participants personally perform OASI repair. Overall, participants matched 64% of evidence-based answers. OASI education/training courses were attended by 30% of respondents, and 44% knew of OASI protocols within their group/institution. Of all factors evaluated, the percent of evidence-based responses was only different for respondent education/CME and protocols. Quality initiatives regarding OASI prevention and management may improve care. Our data suggest OASI training for midwives may improve delivery care in the US. Further studies of other obstetric providers are needed.

Objectives Despite their growing prevalence, pelvic floor disorders (PFDs) remain undertreated and not well understood by patients, with treatment disparities noted in specific subgroups of women. The goal of the present study was to determine the basic understanding of PFDs of women in the southern Appalachian region of the United States, to determine factors that predict knowledge, and to explore the possible disparities in seeking access to care among women in this region who reported symptoms. Methods A survey of patient knowledge of PFDs, specifically urinary incontinence (UI) and pelvic organ prolapse (POP), was conducted in Johnson City, Tennessee, and involved 305 female patients from this city and the surrounding region. Results Almost half of the participants (43%) reported UI symptoms, with only 25% of these participants reporting treatment. A much smaller percentage (5%) reported POP symptoms, but 44% reported receiving treatment. Overall proficiency for UI knowledge was 54.4%, and 69.5% for POP knowledge. Higher UI knowledge was predicted (P $50,000, more than a high school education, and being married. UI knowledge was unrelated to the presence of UI symptoms, receipt of UI treatment, or having seen a urospecialist. Higher POP knowledge was predicted (P $50,000, more than a high school education, and presence of POP symptoms. The only factor significantly predicting seeking treatment among women with UI symptoms was marital status. Conclusions Overall knowledge of both UI and POP was reasonably high in this population, suggesting appropriate self-education or education by providers in the region. The women most affected by UI, particularly those older than 60 years, were not well informed, and education by providers does not appear to specifically target women seeking treatment. We must continue to educate and further reduce the gap of knowledge and treatment regarding PFDs in southern Appalachia.

Gestational diabetes (GDM) occurs in up to 9% of pregnancies. Perinatal depression affects up to 20% of women during pregnancy, and can extend into the postpartum period. A number of studies have linked depression and diabetes, however, whether this applies to GDM or which might come first is less understood. The purpose of this study was to examine the potential relationship between depression identified in the first trimester of pregnancy and the subsequent development of GDM. Women without pre-existing Type I/II diabetes (n = 1021) were evaluated for depression during the first trimester of pregnancy, and medical records were reviewed to identify a positive history of diabetes. Women identified as depressed during the first trimester were more likely to have GDM compared to those not depressed. After controlling for demographic factors and weight-related variables level of depression in the first trimester still predicted later GDM development. Depression identified in early pregnancy may predict increased risk of subsequent GDM development. Due to the numerous maternal, fetal and neonatal complications associated with GDM, early recognition is essential to promote the best possible outcomes for mother and infant. Recognizing depression as a possible risk factor for GDM development could lead to earlier screening and preventative measures.

An increasing number of women are serving in the military. We initiated a retrospective study to evaluate vitamin D status and monitoring in female veterans, and to examine the potential link between vitamin D status, age, race, post-traumatic stress disorder (PTSD), health care costs, and utilization. Approximately 44 percent of the 3,608 female veterans evaluated between 2001 and 2010 were vitamin D deficient (25(OH)D20 ng/ml), a rate substantially higher than that of the general population. While younger (55 years) and older (55+ years) women did not differ significantly in initial vitamin D status, older women had significantly more vitamin D monitoring and follow-up testing than younger women. Approximately 44 percent of vitamin D deficient women did not receive follow-up vitamin D testing. Minority female veterans were most likely to be vitamin D deficient. Female veterans with PTSD did not differ from others regarding their initial vitamin D status; those that were initially deficient were significantly more likely to receive follow-up testing and were more likely to achieve a replete state. Vitamin D deficiency in female veterans was also associated with increased health-care costs. Appropriate monitoring and replacement of vitamin D should be offered to all female veterans.

Little attention has been given to differences in obesity risk factors by racial/ethnic groups. Using data from the 2011-2012 California Health Interview Survey, we examined differences in risk factors for obesity among Whites, Latinos, Asians, and African Americans among 42,935 adults (24.8% obese). Estimates were weighted to ensure an unbiased representation of the Californian population. Multiple logistic and linear regression analyses were used to examine the differences in risk factors for obesity. Large ethnic disparities were found in obesity prevalence: Whites (22.0%), Latinos (33.6%), African Americans (36.1%), and Asians (9.8%). Differences in risk factors for obesity were also observed: Whites (gender, age, physical activity, smoking, arthritis, and diabetes medicine intake), Latinos (age, arthritis, and diabetes medicine intake), Asians (age, binge drinking, arthritis, and diabetes medicine intake), and African Americans (gender, physical activity, smoking, binge drinking, and diabetes medicine intake). Females were more likely to be obese among African Americans (odds ratio (OR) = 1.43, 95% confidence interval (CI) = 1.05–1.94), but less likely among Whites (OR = 0.80, 95% CI = 0.74–0.87). Race/ethnicity should be considered in developing obesity prevention strategies.

The purpose of this study was to investigate the relative contributions of previously identified Polycystic ovary syndrome (PCOS) manifestations (infertility, hirsutism, obesity, menstrual problems) to multiple psychological symptoms. Participants were 126 female endocrinology patient volunteers diagnosed with PCOS who completed a cross-sectional study of PCOS manifestations and psychological symptoms. Participants had significantly elevated scores on nine subscales of psychological symptoms. Menstrual problems were significantly associated with all symptom subscales as well as the global indicator, while hirsutism and obesity were significantly related to five or more subscales. After controlling for demographic factors, menstrual problems were the strongest predictor of psychological symptoms. Findings suggest features of excess body hair, obesity, and menstrual abnormalities carry unique risks for adverse psychologic symptoms, but menstrual problems may be the most salient of these features and deserve particular attention as a marker for psychological risk among women with PCOS.

Although physical abuse during pregnancy has been linked to poor birth outcomes, the role of psychological abuse is less well understood. Associations between birth outcomes and types of psychological abuse during pregnancy (being threatened, screamed at, or insulted) were examined in 489 women with no history of physical abuse. Being threatened was significantly associated with adverse birth outcomes, with women reporting any instance during pregnancy twice as likely to deliver a low birth weight baby. These results remained after controlling for background factors. Finally, most of the variance between threats and birth weight was accounted for by mediating health behaviors (specifically prenatal care utilization and pregnancy weight gain), suggesting pathways for the negative effects of being threatened by an intimate partner during pregnancy.

Religious Commitment is a construct known to be predictive of various health-related factors of importance to researchers. However, data collection efficiency and instrument brevity in healthcare settings are priorities regardless of the construct being measured. Brief, valid instruments are particularly valuable in health research and will be vital for testing mechanisms by which health may be improved or maintained. This series of studies aims to demonstrate that Religious Commitment can be validly measured with a very brief instrument, the Religious Surrender & Attendance Scale-3 (RSAS-3), which combines a 2-item measure of Surrender, a specific type of religious coping, with a 1-item measure of Attendance at religious services. Three studies are reported, two utilizing undergraduate university students (Ns = 964 and 466) and one utilizing a clinical-based pregnant population (N = 320), all in southern Appalachia. The original 12-item Surrender Scale, a 2-item subset of Surrender items, and Attendance were found to be highly positively correlated with each other and with Intrinsic Religiosity, an additional measure of Religious Commitment employed to demonstrate concurrent validity. Religiosity variables were found to be strongly negatively correlated with Anxiety and stress, which were the health outcomes of interest. Hierarchical multiple regression analysis was used to confirm the similarity of Anxiety and stress prediction using the 12-item and 2-item Surrender measures and to confirm the superior stress prediction of the 3-item instrument RSAS-3. The RSAS-3 is recommended as a measure of Religious Commitment in future health research.

Objective To examine the relationship between pre-pregnancy weight and body image concerns and smoking status in late pregnancy. Methods Participants included 172 pregnant smokers. Pre-pregnancy weight and body image concerns were assessed during first trimester via the Weight Concern Scale and Body Image Concern Inventory. Smoking status was evaluated at third trimester via self-report. Results Logistic regression analyses revealed that weight concerns played a significant role in smoking continuation in late pregnancy. Conclusions Beliefs about weight control properties of cigarettes may play an important role in smoking continuation among pregnant women. These findings suggest assessing weight concerns with pregnant women who smoke in an effort to facilitate successful cessation.

Objectives: Veterans of the armed forces, like most population groups, have a high prevalence of vitamin D deficiency, which may be associated with adverse outcomes in several types of cancer. Ultraviolet irradiation is inversely linked with the risk of bladder cancer, presumably through enhanced vitamin D synthesis. We hypothesized that variations in vitamin D status and monitoring predict adverse outcomes in bladder cancer among veterans. Methods: A retrospective analysis of data in the Veterans Integrated Service Network-9 (southeastern United States) was performed for patients diagnosed between October 1, 1999 and February 29, 2008. Age, tobacco exposure, body mass index, and latitude and seasonality of sampling were included as variables in addition to serum vitamin 25(OH)D levels. Results: Monitoring of vitamin D and vitamin D levels and status were closely linked to survival in bladder cancer. Both the chances of survival and longevity improved with enhanced vitamin D status and monitoring. Veterans with bladder cancer had better outcomes if the initial vitamin D level was higher and had more monitoring of the vitamin. Initial vitamin D levels were more strongly related to outcomes than follow-up levels. The link between vitamin D and outcomes remained after adjusting for background variables such as age, body mass index, latitude, seasonality, and tobacco exposure. Conclusions: Findings suggest that adequate vitamin D levels early in the course of the disease provide the best opportunity to improve outcomes. Ensuring that veterans with bladder cancer have adequate vitamin D reserves with appropriate monitoring may play a role in improving outcomes in bladder cancer.

Short interpregnancy interval (IPI),18 months between pregnancies, is a potential cause of adverse delivery and birth outcomes, and may be a particular issue among those with other risks. Our goal was to examine IPI and delivery/infant complications in Tennessee.Birth certificate/vital records data included 101,912 women with a previous delivery. IPI groups (6, 6-12, 12-18, 18-60 months) were compared on outcomes.Thirty-nine percent of the deliveries had IPI18 months, 9% were6 months, rates 11% and 27% higher than nationally. Women with IPI18 months were younger, lower educated with lower income, had higher BMIs, and were more likely to be unmarried, smokers, and have begun prenatal care later (p .001). In adjusted analyses, IPI18 months predicted elevated risk for precipitous labor, low-birth weight, preterm delivery, NICU admission, and infant mortality, with effects strongest for IPI6 months. Finally, risks related to IPI6 months were substantially higher for the lowest income women.Rates of less than optimal IPI were high in this population already experiencing significant maternal-child health disparities, with short IPI a particular risk factor for poor outcomes for the most disadvantaged women, suggesting yet another precursor for adverse birth outcomes in those already most at risk.

Background The pleckstrin and Sec7 domain-containing 3 ( PSD3 ) gene has been linked to immune diseases. We examined whether the genetic variants within the PSD3 gene are associated with obesity, type 2 diabetes (T2D), and high-density lipoprotein (HDL) cholesterol level. Methods Multiple logistic regression model and linear regression model were used to examine the associations of 259 single nucleotide polymorphisms (SNPs) within the PSD3 gene with obesity and T2D as binary traits, and HDL level as a continuous trait using the Marshfield data, respectively. A replication study of obesity was conducted using the Health Aging and Body Composition (Health ABC) sample. Results 23SNPs were associated with obesity ( p p =3.97×10 −6 ). Of the 23SNPs, 20 were significantly associated with obesity in the meta-analysis of two samples ( p p =3.05×10 −3 ); while two SNPs (rs6983992 and rs7843239) were associated with both obesity and T2D ( p =0.0188 and 0.023 for obesity and p =8.47×10 −3 and 0.0128 for T2D, respectively). Furthermore, 11SNPs revealed associations with HDL level (top SNP rs13254772 with p =2.79×10 −3 ) in the Marshfield data; meanwhile rs7009615 was associated with both T2D ( p =0.038) and HDL level ( p =4.44×10 −3 ). In addition, haplotype analyses further supported the results of single SNP analysis. Conclusions Common variants in PSD3 were associated with obesity, T2D and HDL level. These findings add important new insights into the pathogenesis of obesity, T2D and HDL cholesterol.

This “Controversies in Cardiovascular Research” article evaluates the evidence for and against the hypothesis that the circulating blood level of growth differentiation factor 11 (GDF11) decreases in old age and that restoring normal GDF11 levels in old animals rejuvenates their skeletal muscle and reverses pathological cardiac hypertrophy and cardiac dysfunction. Studies supporting the original GDF11 hypothesis in skeletal and cardiac muscle have not been validated by several independent groups. These new studies have either found no effects of restoring normal GDF11 levels on cardiac structure and function or have shown that increasing GDF11 or its closely related family member growth differentiation factor 8 actually impairs skeletal muscle repair in old animals. One possible explanation for what seems to be mutually exclusive findings is that the original reagent used to measure GDF11 levels also detected many other molecules so that age-dependent changes in GDF11 are still not well known. The more important issue is whether increasing blood [GDF11] repairs old skeletal muscle and reverses age-related cardiac pathologies. There are substantial new and existing data showing that GDF8/11 can exacerbate rather than rejuvenate skeletal muscle injury in old animals. There is also new evidence disputing the idea that there is pathological hypertrophy in old C57bl6 mice and that GDF11 therapy can reverse cardiac pathologies. Finally, high [GDF11] causes reductions in body and heart weight in both young and old animals, suggestive of a cachexia effect. Our conclusion is that elevating blood levels of GDF11 in the aged might cause more harm than good.

Alcohol consumption during pregnancy is one potential risk factor for spontaneous abortion (SAb). Prior research suggested that heavy drinking during pregnancy was associated with significantly increased rates of SAb, but results for lower levels of drinking have been inconsistent. We examined the association between different levels and patterns of prenatal alcohol consumption and SAb in a high-risk inner-city sample. We hypothesized that higher levels, binge patterns, and more frequent drinking would be associated with increased rates of SAb. The quantity and frequency of self-reported peri-conceptional and repeated in-pregnancy maternal drinking volumes per beverage type were assessed with semi-structured interviews in a prospective subsample of 302 African-American mothers. Relations between various measures of prenatal alcohol exposure and SAb were assessed using logistic regression. After controlling for various potential confounders, there was a significant positive relation between average absolute alcohol use per day across pregnancy and SAb. Greater frequency of drinking episodes also predicted SAb: an average of even one day of drinking per week across pregnancy was associated with an increase in the incidence of SAb. However, contrary to our hypothesis, neither the amount of alcohol drunk per drinking day nor a measure of binge drinking were significantly related to SAb after controlling for confounders. Differences in when women who drank at risk levels initiated antenatal care may have under-estimated the impact of alcohol on SAb in this low-SES urban African American sample. Some drinking measures averaged across pregnancy may have underestimated consumption and overestimated risk of SAb, but others risk-drinking measures that avoid this limitation show similar relations to SAb. Identifying fetal risk drinking in pregnant women is critical to increasing the effectiveness of interventions that reduce risk-level alcohol consumption and protect from pregnancy loss.

Purpose: Living in a rural region is associated with significant health disparities and increased medical costs. Vitamin D deficiency, which is increasingly common, is also associated with many adverse health outcomes. The purpose of this study was to determine whether rural-urban residence status of veterans was related to vitamin D levels, and to determine if this factor also influenced medical costs/service utilization. Additionally explored was whether vitamin D differences accounted for part of the association between area of residence and medical costs/service utilization. Methods: Medical records of 9,396 veterans from 6 Veterans Administration Medical Centers were reviewed for variables of interest including county of residence, vitamin D level, medical costs and service utilization, and background variables. Rurality status was classified as large metropolitan, urban, and rural. Findings: The 3 rurality status groups differed significantly in vitamin D levels, with the highest levels observed for urban residents, followed by rural residents, and the lowest for large metro residents. Compared with urban residents, large metro residents were 49% more likely, while rural residents were 20% more likely, to be vitamin D deficient. Both rural and large metro residents had higher medical costs, and they were significantly more likely to be hospitalized. Vitamin D levels explained a statistically significant amount of the relationship between rurality status and medical costs/service utilization. Conclusions: Vitamin D deficiency may be an additional health disparity experienced by both rural and inner-city veterans, and patients residing in these locations should be considered at increased risk for deficiency and routinely tested.

Aim: Vitamin D deficiency is a global health issue associated with increased health-care costs, and could play a role in the pathogenesis and management of inflammatory bowel disease. Prior studies show a high prevalence of vitamin D deficiency in veterans with inflammatory bowel disease. We aimed to examine the outcome differences in patients with inflammatory bowel disease, comparing treatment with ergocalciferol to cholecalciferol. Methods: A retrospective review of electronic medical records of patients with inflammatory bowel disease at a Veterans Affairs Medical Facility in the Southeastern United States was carried out. Those with at least one serum 25(OH) vitamin D level were included. Initial and follow-up vitamin D values were recorded. The type of vitamin D supplementation, whether cholecalciferol or ergocalciferol, was documented. Costs in the year after measurement of vitamin D were divided into separate inpatient and outpatient categories. Results: Veterans (n = 108) with ulcerative colitis or Crohn’s disease and an available 25(OH) vitamin D level were studied. There were differences in follow-up vitamin D levels; those who received weekly ergocalciferol had higher subsequent levels than those who received cholecalciferol, especially at a second follow up, although differences did not achieve statistical significance. However, those who received vitamin D3 were less likely to use laboratory, pharmacy, radiology and fee-based services, and had lower laboratory and pharmacy costs. Conclusions: Our data suggest that cholecalciferol replacement might improve outcomes to a greater extent than ergocalciferol, and might be better in limiting health-care costs and expenses in patients with inflammatory bowel disease.

Introduction: Restless legs syndrome (RLS) is a common neurological disorder affecting 10% of the population. Most antidepressants exacerbate symptoms; however, correlational studies have noted symptom improvement with bupropion. The purpose of the current study was to examine whether, in a controlled study, bupropion would improve the symptoms of RLS, or at least not exacerbate them. Methods: This was a double-blinded, randomized controlled trial. Twenty-nine participants with moderate to severe RLS received 150 mg sustained-release bupropion once daily, and 31 control participants received a placebo. Participants were followed for 6 weeks and completed standardized tools, including the International Restless Legs Syndrome Study Group (IRLSSG) severity scale. Results: The primary outcome was change from baseline in IRLSSG severity score; lower scores were associated with improved symptoms. At 3 weeks, IRLSSG scores were 10.8 points lower in the bupropion group and 6.0 points lower in the placebo group (P .016). At 6 weeks, IRLSSG scores were10.4 points lower in the bupropion group and 7.6 points lower in the placebo group (P .108). Bupropion was more effective than placebo in the treatment of RLS at 3 weeks; however, this difference was not statistically significant at 6 weeks. Conclusions: The data from our study suggest that bupropion does not exacerbate the symptoms of RLS and may be a reasonable choice if an antidepressant is needed in individuals with RLS. Larger studies that include titration of bupropion should be considered to determine if bupropion is appropriate for primary treatment of RLS, particularly considering the lower cost and favorable side effect profile compared with currently recommended first-line dopamine agonists.

Methicillin resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (P. aeruginosa) infections are frequently associated with hospitalization and increased healthcare costs. Vitamin D deficiency may contribute to increased costs for patients with these infections and there is evidence that vitamin D may have an antimicrobial role. To evaluate the role of vitamin D deficiency in the costs incurred with these infections, we studied the relationship of serum 25(OH)D levels to healthcare costs in veterans in the southeastern United States. Patients with both infections were vitamin D deficient to a similar extent and so were combined for further analysis. Vitamin D deficient patients had higher costs and service utilization than those who were not vitamin D deficient. Those with vitamin D deficiency had higher inpatient costs compared to the non-deficient group, and this difference was across most categories except for the number of inpatient hospitalizations or total number of days as an inpatient. Vitamin D deficiency was not significantly related to outpatient cost or service utilization parameters. We conclude that vitamin D deficiency is intimately linked to adverse healthcare costs in veterans with MRSA and P. aeruginosa infections. Vitamin D status should be assayed in patients with these infections.

Objectives Peripheral arterial disease (PAD) is a common and often overlooked entity responsible for considerable morbidity and mortality. Recent evidence suggests that nontraditional risk factors such as vitamin D may contribute to atherosclerosis. We hypothesized that vitamin D status was associated with cardiovascular risk factors and that vitamin D deficiency (25(OH)D Design We reviewed medical records of 1435 veterans between 2000 and 2008 in Tennessee via retrospective chart analysis using correlations, logistic regressions, t tests, and χ 2 analyses. Results Vitamin D status was significantly and inversely correlated with body mass index (BMI), glucose, and triglyceride values. Hypertension and diabetes but not smoking also emerged as significantly associated. Of the sample population, 5.2% (n = 75) had an amputation performed. Those individuals who were vitamin D deficient had a significantly higher amputation rate (6.7%) compared with patients who were nondeficient (4.2%). BMI, triglyceride, total cholesterol, hypertension, and diabetes were found to account for 5.7% of the variation in amputation status. Vitamin D concentration and deficiency status accounted for a nonsignificant amount of additional variance. Conclusions We conclude that vitamin D deficiency is closely linked to increased adiposity, triglyceride, and glucose measurements. Vitamin D deficiency was associated with an increased amputation risk in veterans with PAD and appears to mediate its effects through traditional risk factors.

Vitamin D insufficiency remains a costly pandemic in veterans. Treatment requires achievement of desired 25-hydroxyvitamin D [25(OH)D] concentrations. The frequency with which 25(OH)D should be measured following treatment remains speculative. A retrospective analysis of veterans with vitamin D insufficiency was conducted. The group was stratified on the basis of initial 25(OH)D and assessed for frequency of follow-up 25(OH)D concentrations. Over 3 years, 278 patients with insufficient 25(OH)D concentrations were identified. Of these, 87 (31%) patients had subsequent levels assessed in the year following initial documentation of vitamin D insufficiency. The likelihood of follow-up testing was unrelated to the initial vitamin D level. In the patients with follow-up 25(OH)D levels, 90% eventually achieved a serum level of 30 ng/mL or greater. Veterans with vitamin D insufficiency have inadequate serial monitoring of 25(OH)D concentrations.

Background: In 2000, the American College of Obstetricians/Gynecologists (ACOG) established the 5 A's method of brief smoking cessation counseling (ask, advise, assess, assist, arrange) as a standard component of prenatal care. The purpose of this study was to describe use of the 5 A's in prenatal care in Northeast Tennessee, where pregnancy smoking rates are three times the national average, and to evaluate provider attitudes toward addressing pregnancy smoking. Method: Surveys were distributed to all obstetric practices in a 6-county area. Results: One-quarter of respondents indicated they always asked pregnant patients about smoking, with two-thirds always giving their pregnant smokers advice to quit. Over half reported always assessing willingness to quit, while one-quarter or fewer always provided quit assistance, or arranged follow up. Over half believed addressing smoking was of significant value. Secondhand smoke was infrequently addressed. Demographics, efficacy, and outcome beliefs predicted use of the 5 A's. Conclusions: Most obstetric providers in Northeast Tennessee are not following ACOG recommendations for pregnancy smoking. Efforts to address pregnancy smoking and associated adverse pregnancy outcomes in the region should include facilitation of smoking cessation interventions in prenatal care.

Context: Rates of preterm birth (PTB) and low birth weight (LBW) vary by region, with disparities particularly evident in the Appalachian region of the South. Community conditions related to rurality likely contribute to adverse birth outcomes in this region. Purpose: This study examined associations between rurality and related community conditions, and newborn outcomes in southern Appalachia, and explored whether pregnancy smoking explained such associations. Methods: Data for all births in a southern Appalachian county over a 2-year period were extracted from hospital records. Findings: Data were available for 4,144 births, with 45 different counties of residence. Babies born to women from completely rural counties, on average, weighed 700 g less, were 1.5 inches shorter, and were born over 3 weeks earlier than less rural infants. In addition, these babies were 4.5 times more likely to be LBW, 4 times more likely to be PTB, and 5 times more likely to be admitted to the neonatal intensive care unit (NICU). Effects were also found for per capita income, poverty rate, and unemployment rate, all of which were associated with rurality. Some, but not all of the association was explained by elevated rates of pregnancy smoking. Conclusions: Babies born to women residing in rural and economically depressed counties in southern Appalachia are at substantially increased risk for poor birth outcomes. Improving these outcomes in the rural South will likely require addressing access to health services and information, health care provider retention, transportation services, employment opportunities, and availability of public health services including smoking cessation assistance.

Vitamin D deficiency is often unrecognized and has been linked to many chronic diseases. Vitamin D supplementation has been shown to ameliorate these chronic diseases and may reduce the prevalence of some cancers. We analyzed the health care costs associated with vitamin D deficiency in Veterans in Northeast Tennessee. A retrospective electronic chart analysis of the relationship of 25-hydroxyvitamin D [25(OH)D] status to health care costs, services, and utilization was done in 886 veterans. The overall costs were higher by 39% in the vitamin D-deficient group. Vitamin D deficiency was associated with increased service utilization in many areas including more frequent emergency room and clinic visits as well as increased inpatient stay and inpatient services. The serum level of vitamin D was also related to health care costs, although to a lesser extent. Vitamin D deficiency is closely linked to increased health care costs in veterans.
