Enhancing Participation in Depression Care in Outpatient Perinatal Care Settings: A Systematic Review. - Obstetrics and gynecology
To examine a wide range of study designs and outcomes to estimate the extent to which interventions in outpatient perinatal care settings are associated with an increase in the uptake of depression care.PubMed, CINAHL, PsycINFO, ClinicalTrials.gov, and Scopus (EMBASE) were searched for studies published between 1999 and 2014 that evaluated mental health care use after screening for depression in perinatal care settings.Inclusion criteria were: 1) English language; 2) pregnant and postpartum women who screened positive for depression; 3) exposure (validated depression screening in outpatient perinatal care setting); and, 4) outcome (mental health care use). Searches yielded 392 articles, 42 met criteria for full-text review, and 17 met inclusion criteria. Study quality was assessed using a modified Downs and Black scale.Articles were independently reviewed by two abstractors and consensus reached. Study design, intervention components, and mental health care use were defined and categorized. Seventeen articles representing a range of study designs, including one randomized controlled trial and one cluster randomized controlled trial, were included. The average quality rating was 61% (31.0-90.0%). When no intervention was in place, an average of 22% (13.8-33.0%) of women who screened positive for depression had at least one mental health visit. The average rate of mental health care use was associated with a doubling of this rate with patient engagement strategies (44%, 29.0-90.0%), on-site assessments (49%, 25.2-90.0%), and perinatal care provider training (54%, 1.0-90.0%). High rates of mental health care use (81%, 72.0-90.0%) were associated with implementation of additional interventions, including resource provision to women, perinatal care provider training, on-site assessment, and access to mental health consultation for perinatal care providers.Screening alone was associated with 22% mental health care use among women who screened positive for depression; however, implementation of additional interventions was associated with a two to fourfold increased use of mental health care. Although definitive studies are still needed, screening done in conjunction with interventions that target patient, health care provider, and practice-level barriers is associated with increased improved rates of depression detection, assessment, referral, and treatment in perinatal care settings.
Human adipose tissue expansion in pregnancy is impaired in gestational diabetes mellitus. - Diabetologia
During pregnancy, adipose tissue (AT) must expand to support the growing fetus and the future nutritional needs of the offspring. Limited expandability of AT is associated with insulin resistance, attributed to ectopic lipid deposition. This study aimed to investigate human AT expandability during pregnancy and its role in the pathogenesis of gestational diabetes mellitus (GDM).This cross-sectional study of omental (OM) and subcutaneous (SQ) AT collected at Caesarean delivery included 11 pregnant and three non-pregnant women with normal glucose tolerance (NGT), five with GDM, three with type 2 diabetes mellitus. Adipocyte size, capillary density, collagen content and capillary growth were measured. Affymetrix arrays and real-time PCR studies of gene expression were performed.Mean OM adipocyte size was greater in women with GDM than in those with NGT (p = 0.004). Mean OM and SQ capillary density was lower in GDM compared with NGT (p = 0.015). Capillary growth did not differ significantly between groups. The most differentially expressed AT transcript when comparing non-pregnant and pregnant women corresponded to the IGF binding protein (IGFBP)-5, the expression levels of which was found by subsequent quantitative real-time PCR to be lower in women with GDM vs women with NGT (p < 0.0001).The relative OM adipocyte hypertrophy and decreased OM and SQ capillary density are consistent with impaired AT expandability in GDM. The induction of adipose tissue IGFBP5 in pregnancy and its decrease in GDM point to the importance of the IGF-1 signalling pathway in AT expansion in pregnancy and GDM susceptibility.
Infection of ectocervical tissue and universal targeting of T-cells mediated by primary non-macrophage-tropic and highly macrophage-tropic HIV-1 R5 envelopes. - Retrovirology
HIV-1 variants carrying non-macrophage-tropic HIV-1 R5 envelopes (Envs) are predominantly transmitted and persist in immune tissue even in AIDS patients who have highly macrophage-tropic variants in the brain. Non-macrophage-tropic R5 Envs require high levels of CD4 for infection contrasting with macrophage-tropic Envs, which can efficiently mediate infection of cells via low CD4. Here, we investigated whether non-macrophage-tropic R5 Envs from the acute stage of infection (including transmitted/founder Env) mediated more efficient infection of ectocervical explant cultures compared to non-macrophage-tropic and highly macrophage-tropic R5 Envs from late disease.We used Env+ pseudovirions that carried a GFP reporter gene to measure infection of the first cells targeted in ectocervical explant cultures. In straight titrations of Env+ pseudovirus supernatants, mac-tropic R5 Envs from late disease mediated slightly higher infectivities for ectocervical explants although this was not significant. Surprisingly, explant infection by several T/F/acute Envs was lower than for Envs from late disease. However, when infectivity for explants was corrected to account for differences in the overall infectivity of each Env+ pseudovirus (measured on highly permissive HeLa TZM-bl cells), non-mac-tropic early and late disease Env+ pseudoviruses mediated significantly higher infection. This observation suggests that cervical tissue preferentially supports non-mac-tropic Env+ viruses compared to mac-tropic viruses. Finally, we show that T-cells were the main targets for infection regardless of whether explants were stimulated with T-cell or monocyte/macrophage cytokines. There was no evidence of macrophage infection even for pseudovirions carrying highly mac-tropic Envs from brain tissue or for the highly mac-tropic, laboratory strain, BaL, which targeted T-cells in the explant tissue.Our data support ectocervical tissue as a favorable environment for non-mac-tropic HIV-1 R5 variants and emphasize the role of T-cells as initial targets for infection even for highly mac-tropic variants.
Pregnancy intention, receipt of pre-conception care, and pre-conception weight counseling reported by overweight and obese women in late pregnancy. - Sexual & reproductive healthcare : official journal of the Swedish Association of Midwives
We surveyed overweight or obese women receiving prenatal care for a singleton pregnancy at a large academic medical center in 2010. During late pregnancy, women reported pregnancy intentionality and pre-conception weight counseling. Participants (N = 82) had a mean age of 29.7 (SD: 6.3) years, 61% were non-Hispanic white, 47% were nulliparous. Before pregnancy, 45% were overweight and 55% were obese. Forty-eight percent reported that the current pregnancy was planned. Of these women, 36% reported a pre-conception visit. Of these, 29% reported pre-conception weight counseling (5% of sample). Unrealized opportunities exist in the clinical setting for promoting weight management during the childbearing years.Copyright © 2015 Elsevier B.V. All rights reserved.
Understanding multifactorial influences on the continuum of maternal weight trajectories in pregnancy and early postpartum: study protocol, and participant baseline characteristics. - BMC pregnancy and childbirth
Maternal and offspring immediate and long-term health are affected by pregnancy weight gain and maternal weight. This study was designed to determine feasibility of: 1) recruiting a socio-economically and racially/ethnically diverse sample of pregnant women into a longitudinal observational study, including consenting the women for serial biologic specimen evaluations; 2) implementing comprehensive assessments (including biologic, anthropometric, behavioral, cognitive/psychosocial and socio-demographic, and cultural measures) at multiple time points over the study period, including collecting biologic specimens at planned and unplanned pregnancy delivery times; and 3) retaining the sample for one year into the postpartum period. Additionally, the study will provide preliminary data of associations among hypothesized predictors, mediators and moderators of pregnancy and post-partum maternal and infant weight trajectories. The study was conceptualized under a Biopsychosocial Model using a lifespan approach. Study protocol and baseline characteristics are described.We sought to recruit a sample of 100 healthy women age 18-45 years, between 28-34 weeks gestation, with singleton pregnancies, enrolled in care prior to 17 weeks gestation. Women provide written consent for face-to-face (medical history, anthropometrics, biologic specimens), and paper-and-pencil assessments, at five time points: baseline (third trimester), delivery-associated, and 6-weeks, 3-months and 6-months postpartum. Additional telephone-based assessments (diet, physical activity and breastfeeding) administered baseline and three-months postpartum. Infant weights are collected until 1-year of life. We seek to retain 80% of participants at six-months postpartum and 80% of offspring at 12-months. 110 women were recruited. Sample characteristics include: mean age 28.3 years, BMI 25.7 kg/m(2), and gestational age at baseline visit of 32.5 weeks. One-third of cohort was non-white, over a quarter were Latina, and almost a quarter were non-US born. The cohort majority was multigravida, had graduated high school and/or had higher levels of education, and worked outside the home.Documentation of study feasibility and preliminary data for theory-driven hypothesis of maternal and child factors associated with weight trajectories will support future large scale longitudinal studies of risk and protective factors for maternal and child health. This research will also inform intervention targets facilitating healthy maternal and child weight.
Pregnant women's interest in a website or mobile application for healthy gestational weight gain. - Sexual & reproductive healthcare : official journal of the Swedish Association of Midwives
We examined pregnant women's interest in using a website or mobile application to help them gain a healthy amount of weight during pregnancy. Pregnant women (N = 64) completed a short questionnaire during routine prenatal care at hospital-based obstetric clinics in central Massachusetts during April-August 2012. Eighty-six percent reported interest in using a website or mobile application to help them gain a healthy amount of weight; interest ranged from 67% to 100% across demographics, clinical characteristics, and technology use. The Internet is a promising modality for delivering interventions to prevent excessive gestational weight gain and associated maternal and child health consequences.Copyright © 2014 Elsevier B.V.

Patient report of guideline-congruent gestational weight gain advice from prenatal care providers: differences by prepregnancy BMI. - Birth (Berkeley, Calif.)
Prenatal care provider weight gain advice consistent with the Institute of Medicine recommendations is related to guideline-adherent gestational weight gain (GWG), yet many women may not receive guideline-congruent advice. We examined pregnant women's recall of prenatal care provider GWG advice in relation to prepregnancy body mass index (BMI).We conducted a prospective cohort study of women (n = 149) receiving prenatal care for a singleton pregnancy at a large academic medical center in 2010. Data were collected via a survey during late pregnancy and medical record abstraction.Thirty-three percent of women did not recall receiving the provider GWG advice; 33 percent recalled advice consistent with 2009 Institute of Medicine recommendations. Recalled advice differed by prepregnancy BMI; 29 percent of normal weight, 26 percent of overweight, and 45 percent of obese women reported not receiving advice, and 6, 37, and 39 percent, respectively, recalled advice exceeding Institute of Medicine recommendations. Among the 62 percent who recalled that their provider had labeled their prepregnancy BMI, 100 percent of normal weight, 32 percent of overweight, and 23 percent of obese women recalled the labels "normal weight," "overweight," and "obese," respectively.Helping providers give their patients memorable and guideline-consistent GWG advice is an actionable step toward preventing excessive GWG and associated maternal and child health consequences.© 2014 Wiley Periodicals, Inc.
Depression and anxiety among high-risk obstetric inpatients. - General hospital psychiatry
To assess the following among women hospitalized antenatally due to high-risk pregnancies: (1) rates of depression symptoms and anxiety symptoms, (2) changes in depression symptoms and anxiety symptoms and, (3) rates of mental health treatment.Sixty-two participants hospitalized for high-risk obstetrical complications completed the Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder 7-item scale (GAD-7) and Short-Form 12 weekly until delivery or discharge, and once postpartum.Average length of total hospital stay was 8.3 ± 7.6 days for women who completed an initial admission survey (n = 62) and 16.3 ± 8.9 (n = 34), 25.4 ± 10.2 (n = 17) and 35 ± 10.9 days (n = 9) for those who completed 2, 3 and 4 surveys, respectively. EPDS was ≥ 10 in 27% (n=17) and GAD-7 was ≥ 10 in 13% (n = 8) of participants at initial survey. Mean anxiety (4.2 ± 6.5 vs. 5.2 ± 5.1, p = .011) and depression (4.4 ± 5.6 vs. 6.9 ± 4.8, p = .011) scores were lower postpartum compared to initial survey. Past mental health diagnosis predicted depression symptoms [odds ratio (OR) = 4.54; 95% confidence interval (CI) 1.91-7.17] and anxiety symptoms (OR = 5.95; 95% CI 3.04-8.86) at initial survey; however, 21% (n = 10) with no diagnostic history had EPDS ≥ 10. Five percent (n = 3) received mental health treatment during pregnancy.Hospitalized high-risk obstetrical patients may commonly experience depression symptoms and/or anxiety symptoms and not receive treatment. A history of mental health treatment or diagnosis was associated with depression symptoms or anxiety symptoms in pregnancy. Of women with an EPDS ≥ 10, > 50% did not report a past mental health diagnosis.Copyright © 2014 Elsevier Inc. All rights reserved.
Cigarette smoking and gestational diabetes mellitus in Hispanic woman. - Diabetes research and clinical practice
Hispanic women are at increased risk of gestational diabetes mellitus (GDM) as compared to non-Hispanic white women. While smoking has been associated with increased risk of type 2 diabetes, studies of smoking and GDM are sparse and conflicting. Therefore, we evaluated the relationship between cigarette smoking and GDM in Hispanic women.We conducted a pooled analysis of two Hispanic datasets based in Massachusetts: the UMass Medical Health Care dataset and the Proyecto Buena Salud dataset. A total of 3029 Hispanic prenatal care patients with singleton gestations were included. Cigarette smoking prior to and during pregnancy was collected via self-report. Diagnosis of GDM was abstracted from medical records and confirmed by study obstetricians.One-fifth of participants (20.4%) reported smoking prior to pregnancy, and 11.0% reported smoking in pregnancy. A total of 143 women (4.7%) were diagnosed with GDM. We did not observe an association between pre-pregnancy cigarette smoking and odds of GDM (multivariable OR=0.77, 95% CI 0.47, 1.25). In contrast, smoking during pregnancy was associated with a 54% reduction in odds of GDM (OR=0.46, 95% CI 0.22, 0.95). However, this association was no longer statistically significant after adjustment for age, parity, and study site (OR=0.47, 95% CI 0.23, 1.00).In this population of Hispanic pregnant women, we did not observe statistically significant associations between pre-pregnancy smoking and odds of GDM. A reduction in odds of GDM among those who smoked during pregnancy was no longer apparent after adjustment for important diabetes risk factors.Copyright © 2014 Elsevier Ireland Ltd.

What happens to mental health treatment during pregnancy? Women's experience with prescribing providers. - The Psychiatric quarterly
This exploratory study completed interviews with 25 depressed pregnant women who had prior depression, and when becoming pregnant, were receiving depression medication or tried to get mental health care. Seventy one percent of women were more than 25 weeks gestation at the time of the interview. Thirty-five percent of women were not receiving treatment. While 94 % told their provider of their pregnancy, 36 % had no opportunity to discuss the risks and benefits of continued pharmacotherapy; 42 % had no opportunity to continue pharmacotherapy. Some providers may be reluctant to treat depressed pregnant women, creating a potential barrier to their receipt of needed care.
