Historical Perspectives: Unsilencing Suffering: Promoting Maternal Mental Health in Neonatal Intensive Care Units

Mothers of infants in the NICU suffer higher rates of psychological distress, anxiety, and depression compared with the general population. Often, their mental health concerns remain underidentified and undertreated, which can have deleterious effects on the offspring, both in short-term outcomes while in the NICU as well as long-term neurodevelopmental and behavioral outcomes. In this review, we present an overview of existing empirical evidence about how maternal mental health affects the health of infants, special considerations regarding the mental health needs of NICU mothers, and the findings about existing and developing interventions to address mental health concerns in this vulnerable population

Reducing Cardiovascular Disease Risk In Mid-Life and Older African Americans: A Church-Based Longitudinal Intervention Project At Baseline

Introduction: African Americans (AAs) experience higher age-adjusted morbidity and mortality than Whites for cardiovascular disease (CVD). Church-based health programs can reduce risk factors for CVD, including elevated blood pressure [BP], excess body weight, sedentary lifestyle and diet. Yet few studies have incorporated older adults and longitudinal designs. Purposes: The aims of this study are to: a) describe a theory-driven longitudinal intervention study to reduce CVD risk in mid-life and older AAs; b) compare selected dietary (fruit and vegetable servings/day, fat consumption), physical activity (PA) and clinical variables (BMI, girth circumferences, systolic and diastolic BP, LDL, HDL, total cholesterol [CHOL] and HDL/CHOL) between treatment and comparison churches at baseline; c) identify selected background characteristics (life satisfaction, social support, age, gender, educational level, marital status, living arrangement and medication use) at baseline that may confound results; and d) share the lessons learned. Methods: This study incorporated a longitudinal pre/post with comparison group quasi-experimental design. Community-based participatory research (CBPR) was used to discover ideas for the study, identify community advisors, recruit churches (three treatment, three comparison) in two-counties in North Florida, and randomly select 221 mid-life and older AAs (45 +) (n = 104 in clinical subsample), stratifying for age and gender. Data were collected through self-report questionnaires and clinical assessments. Results and Conclusions: Dietary, PA and clinical results were similar to the literature. Treatment and comparison groups were similar in background characteristics and health behaviors but differed in selected clinical factors. For the total sample, relationships were noted for most of the background characteristics. Lessons learned focused on community relationships and participant recruitment

CMB polarimetry with BICEP: instrument characterization, calibration, and performance

BICEP is a ground-based millimeter-wave bolometric array designed to target the primordial gravity wave signature on the polarization of the cosmic microwave background (CMB) at degree angular scales. Currently in its third year of operation at the South Pole, BICEP is measuring the CMB polarization with unprecedented sensitivity at 100 and 150 GHz in the cleanest available 2% of the sky, as well as deriving independent constraints on the diffuse polarized foregrounds with select observations on and off the Galactic plane. Instrument calibrations are discussed in the context of rigorous control of systematic errors, and the performance during the first two years of the experiment is reviewed.Comment: 12 pages, 15 figures, updated version of a paper accepted for Millimeter and Submillimeter Detectors and Instrumentation for Astronomy IV, Proceedings of SPIE, 7020, 200

Absolute polarization angle calibration using polarized diffuse Galactic emission observed by BICEP

We present a method of cross-calibrating the polarization angle of a polarimeter using BICEP Galactic observations. \bicep\ was a ground based experiment using an array of 49 pairs of polarization sensitive bolometers observing from the geographic South Pole at 100 and 150 GHz. The BICEP polarimeter is calibrated to +/-0.01 in cross-polarization and less than +/-0.7 degrees in absolute polarization orientation. BICEP observed the temperature and polarization of the Galactic plane (R.A= 100 degrees ~ 270 degrees and Dec. = -67 degrees ~ -48 degrees). We show that the statistical error in the 100 GHz BICEP Galaxy map can constrain the polarization angle offset of WMAP Wband to 0.6 degrees +\- 1.4 degrees. The expected 1 sigma errors on the polarization angle cross-calibration for Planck or EPIC are 1.3 degrees and 0.3 degrees at 100 and 150 GHz, respectively. We also discuss the expected improvement of the BICEP Galactic field observations with forthcoming BICEP2 and Keck observations.Comment: 13 pages, 10 figures and 2 tables.

Large-scale associations between the leukocyte transcriptome and BOLD responses to speech differ in autism early language outcome subtypes.

Heterogeneity in early language development in autism spectrum disorder (ASD) is clinically important and may reflect neurobiologically distinct subtypes. Here, we identified a large-scale association between multiple coordinated blood leukocyte gene coexpression modules and the multivariate functional neuroimaging (fMRI) response to speech. Gene coexpression modules associated with the multivariate fMRI response to speech were different for all pairwise comparisons between typically developing toddlers and toddlers with ASD and poor versus good early language outcome. Associated coexpression modules were enriched in genes that are broadly expressed in the brain and many other tissues. These coexpression modules were also enriched in ASD-associated, prenatal, human-specific, and language-relevant genes. This work highlights distinctive neurobiology in ASD subtypes with different early language outcomes that is present well before such outcomes are known. Associations between neuroimaging measures and gene expression levels in blood leukocytes may offer a unique in vivo window into identifying brain-relevant molecular mechanisms in ASD

Characterization of the BICEP Telescope for High-precision Cosmic Microwave Background Polarimetry

The Background Imaging of Cosmic Extragalactic Polarization (BICEP) experiment was designed specifically to search for the signature of inflationary gravitational waves in the polarization of the cosmic microwave background (CMB). Using a novel small-aperture refractor and 49 pairs of polarization-sensitive bolometers, BICEP has completed three years of successful observations at the South Pole beginning in 2006 February. To constrain the amplitude of the inflationary B-mode polarization, which is expected to be at least 7 orders of magnitude fainter than the 3 K CMB intensity, precise control of systematic effects is essential. This paper describes the characterization of potential systematic errors for the BICEP experiment, supplementing a companion paper on the initial cosmological results. Using the analysis pipelines for the experiment, we have simulated the impact of systematic errors on the B-mode polarization measurement. Guided by these simulations, we have established benchmarks for the characterization of critical instrumental properties including bolometer relative gains, beam mismatch, polarization orientation, telescope pointing, sidelobes, thermal stability, and timestream noise model. A comparison of the benchmarks with the measured values shows that we have characterized the instrument adequately to ensure that systematic errors do not limit BICEP's two-year results, and identifies which future refinements are likely necessary to probe inflationary B-mode polarization down to levels below a tensor-to-scalar ratio r = 0.1.Astronom

The relation between gender -stereotyped behavior and adolescent depression: A sequential analysis of adolescent -mother interactions

One of the most commonly reported findings in the epidemiology of psychological disorders is the 2:1 ratio of women to men who suffer from depression, a difference in prevalence rates that first emerges during the adolescent years. Although aspects of the feminine gender role have been identified as risk factors for depressive symptoms, the analysis of interpersonal interaction is rarely used to assess how these constructs may be behaviorally enacted. In this dissertation, interactions between mothers and adolescents were analyzed to identify specific sequences of behavior associated with adolescents\u27 depressive symptoms, with the aim of clarifying reasons for the dramatic increase in depression among adolescent girls. A community sample of 79 adolescents & their families participated over a 3-year period. Thirty-two consecutive segments of a videotaped problem-solving interaction task were viewed by participants and coded on the dimensions of support, conflict, giving-in, humor, misunderstanding , and sarcasm. Using sequential analyses and multiple linear regression, I assessed the extent to which sequences consistent with the feminine gender role (conflict paired with giving-in ) predicted concurrent and future depressive symptoms. Additional exploratory analyses examined maternal reactions to adolescent conflict. Results indicate that the pairing of conflict with giving-in during problem-solving interactions is predictive of future depressive symptoms, and that adolescent sex and history of depressive symptoms moderate this relation. As expected, the behavioral combination of conflict with giving-in was a riskier one for girls and for adolescents with a history of depressive symptoms. Maternal responses to adolescent conflict did not differ when mother-son dyads were compared to mother-daughter dyads

Guess who\u27s coming to therapy? Getting comfortable with conversations about race and ethnicity in psychotherapy

Despite the fact that clinical psychology training programs now typically offer course work in multicultural issues, many professional psychologists may continue to feel unsure about how and when to incorporate multicultural awareness into their everyday clinical work. Having open discussions with clients regarding issues of race and ethnicity is one way to actively include a multicultural element into psychotherapy, as well as to strengthen the therapeutic alliance and promote better treatment outcome. The authors make several recommendations designed to provoke thought and stimulate conversation about race and ethnicity in the context of psychotherapy
