Translational Research of the Acute Effects of Negative Emotions on Vascular Endothelial Health: Findings From a Randomized Controlled Study.

BACKGROUND: Provoked anger is associated with an increased risk of cardiovascular disease events. The underlying mechanism linking provoked anger as well as other core negative emotions including anxiety and sadness to cardiovascular disease remain unknown. The study objective was to examine the acute effects of provoked anger, and secondarily, anxiety and sadness on endothelial cell health. METHODS AND RESULTS: Apparently healthy adult participants (n=280) were randomized to an 8-minute anger recall task, a depressed mood recall task, an anxiety recall task, or an emotionally neutral condition. Pre-/post-assessments of endothelial health including endothelium-dependent vasodilation (reactive hyperemia index), circulating endothelial cell-derived microparticles (CD62E+, CD31+/CD42-, and CD31+/Annexin V+) and circulating bone marrow-derived endothelial progenitor cells (CD34+/CD133+/kinase insert domain receptor+ endothelial progenitor cells and CD34+/kinase insert domain receptor+ endothelial progenitor cells) were measured. There was a group×time interaction for the anger versus neutral condition on the change in reactive hyperemia index score from baseline to 40 minutes (P=0.007) with a mean±SD change in reactive hyperemia index score of 0.20±0.67 and 0.50±0.60 in the anger and neutral conditions, respectively. For the change in reactive hyperemia index score, the anxiety versus neutral condition group by time interaction approached but did not reach statistical significance (P=0.054), and the sadness versus neutral condition group by time interaction was not statistically significant (P=0.160). There were no consistent statistically significant group×time interactions for the anger, anxiety, and sadness versus neutral condition on endothelial cell-derived microparticles and endothelial progenitor cells from baseline to 40 minutes. CONCLUSIONS: In this randomized controlled experimental study, a brief provocation of anger adversely affected endothelial cell health by impairing endothelium-dependent vasodilation.

Measures of executive function may not be indicators of latent constructs.

Executive function (EF) is represented by a multidimensional set of measures. The central EFs considered are inhibitory control, working memory and cognitive flexibility (task shifting). Unlike other ability constructs, it has proven difficult to identify latent factors that underlie EF. Research has often taken a factor analytic approach for grouping executive functioning tasks. However, this approach has often proven unsuccessful. We aimed to compare factor analysis to a network analytic approach, as network analysis can summarize the pattern of relationships among elements without creating latent constructs. One hundred and thirteen undergraduate students completed a series of nine executive functioning tasks. In comparing exploratory factor analysis to network analysis, we found neither approach provided a compelling higher order grouping of EF measures.

A close-in giant planet escapes engulfment by its star.

When main-sequence stars expand into red giants, they are expected to engulf close-in planets1-5. Until now, the absence of planets with short orbital periods around post-expansion, core-helium-burning red giants6-8 has been interpreted as evidence that short-period planets around Sun-like stars do not survive the giant expansion phase of their host stars9. Here we present the discovery that the giant planet 8 Ursae Minoris b10 orbits a core-helium-burning red giant. At a distance of only 0.5 AU from its host star, the planet would have been engulfed by its host star, which is predicted by standard single-star evolution to have previously expanded to a radius of 0.7 AU. Given the brief lifetime of helium-burning giants, the nearly circular orbit of the planet is challenging to reconcile with scenarios in which the planet survives by having a distant orbit initially. Instead, the planet may have avoided engulfment through a stellar merger that either altered the evolution of the host star or produced 8 Ursae Minoris b as a second-generation planet11. This system shows that core-helium-burning red giants can harbour close planets and provides evidence for the role of non-canonical stellar evolution in the extended survival of late-stage exoplanetary systems.

Transfusion in Root Replacement for Aortic Dissection: The STS Adult Cardiac Surgery Database Analysis.

BACKGROUND: Transfusion in acute aortic syndromes has been studied in a limited fashion. We sought to describe contemporary transfusion practice for root replacement in acute (Stanford) type A aortic dissection. METHODS: The Society of Thoracic Surgeons Adult Cardiac Surgery Database was interrogated to identify patients who underwent primary aortic root replacement for acute (Stanford) type A aortic dissection (July 2014 to June 2017). Patients (n = 1558) were stratified by type of root replacement. Multivariate regression was used to determine those variables associated with transfusion and postoperative morbidity. RESULTS: Transfusion was required in 90.5% of cases (n = 1410). Operative mortality for all patients was 17.3% (261 deaths). Intraoperative red blood cell transfusion portended reduced short-term survival (odds ratio [OR] 2.00, P = .025). Massive postoperative transfusion was associated with prolonged ventilation (OR 13.47, P < .001), sepsis (OR 4.13, P < .001), and new dialysis-dependent renal failure (OR 2.43, P < .001). Women were more likely to require transfusion (OR 3.03, P < .001), as were patients who had coronary artery bypass (OR 1.57, P = .009), and those in shock (OR 2.27, P < .001). Valve-sparing aortic root replacement was associated with reduced transfusion requirements vs composite roots. Institutional case volume was not appreciably correlated with transfusion. CONCLUSIONS: Most patients undergoing root replacement for aortic dissection require blood products. Composite root replacement is associated with a greater likelihood of transfusion than a valve-sparing operation. Transfusion independently foreshadows greater operative mortality.

Complex trauma and Trauma-Focused Cognitive-Behavioral Therapy: How do trauma chronicity and PTSD presentation affect treatment outcome?

BACKGROUND: Traumatic experiences are common in youth and can be classified as acute (one incident or short-term) or complex (chronic exposure to multiple traumas) experiences. Posttraumatic stress disorder (PTSD) is a common response to trauma, often co-occurring with other mental health symptoms. According to the International Classification of Diseases, 11th Edition (World Health Organization, 2018), complex PTSD includes difficulties with affect regulation, interpersonal relationships, and self-blame. OBJECTIVE: The aims of this study were to evaluate trauma chronicity and PTSD presentation as moderators of outcomes of trauma-focused cognitive behavior therapy (TF-CBT). PARTICIPANTS AND SETTING: Participants included 176 youth and caregiver dyads who were participants in an ongoing effectiveness study of TF-CBT at a community-based clinic in NYC. METHODS: Multilevel modeling was used to examine longitudinal, within-subject variability. Moderation analyses were used to assess the role of trauma chronicity and levels of PTSD on change in the outcomes. RESULTS: There were no baseline differences between youth with acute versus chronic trauma. At baseline, participants who had PTSD plus 2 or 3 of the ICD-11 Complex PTSD symptom domains had significantly worse functioning than those with simple PTSD. We found significant improvement on most measures of PTSD and complex PTSD domains. Level of improvement was found to vary based on PTSD presentation at baseline. CONCLUSIONS: This is the first study to evaluate both trauma chronicity and PTSD presentation in the context of evidence-based treatment, and findings support the effectiveness of TF-CBT for simple and complex PTSD for youth who have experienced acute and chronic trauma.

Uptake of Task-Strengthening Strategy for Hypertension (TASSH) control within Community-Based Health Planning Services in Ghana: study protocol for a cluster randomized controlled trial.

BACKGROUND: Physician shortage is a major barrier to hypertension (HTN) control in Ghana, with only one physician to 10,000 patients in 2015, thus limiting its capacity for HTN control at the primary care level such as the Community Health Planning and Services (CHPS) compounds, where most Ghanaians receive care. A Task-Shifting Strategy for HTN control (TASSH) based on the WHO Cardiovascular (CV) Risk Package is an evidence-based strategy for mitigating provider- and systems-level barriers to optimal HTN control. Despite its effectiveness, TASSH remains untested in CHPS zones. Additionally, primary care practices in low- and middle-income countries (LMICs) lack resources and expertise needed to coordinate multilevel system changes without assistance. The proposed study will evaluate the effectiveness of practice facilitation (PF) as a quality improvement strategy for implementing TASSH within CHPS zones in Ghana. METHODS: Guided by the Consolidated Framework for Implementation Research and the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework, we will evaluate, in a hybrid clinical effectiveness-implementation design, the effect of PF on the uptake of an evidence-based TASSH, among 700 adults who present to 70 CHPS zones with uncontrolled HTN. Components of the PF strategy include (a) an advisory board that provides leadership support for implementing the intervention within the CHPS zones and (b) trained task-strengthening facilitators (TSFs) who serve as practice coaches to provide training, and performance feedback to community health officers (CHOs) who will deliver TASSH at the CHPS zones. For this purpose, the TSFs are trained to identify, counsel, and refer adults with uncontrolled HTN to community health centers in Bono East Region of Ghana. DISCUSSION: Uptake of community-based evidence-supported interventions for hypertension control in Ghana is urgently needed to address the CVD epidemic and its associated morbidity, mortality, and societal costs. Findings from this study will provide policymakers and other stakeholders the "how to do it" empirical literature on the uptake of evidence-based task-strengthening interventions for HTN control in Ghana and will serve as a model for similar action in other low, middle-income countries.

Very regular high-frequency pulsation modes in young intermediate-mass stars.

Asteroseismology probes the internal structures of stars by using their natural pulsation frequencies1. It relies on identifying sequences of pulsation modes that can be compared with theoretical models, which has been done successfully for many classes of pulsators, including low-mass solar-type stars2, red giants3, high-mass stars4 and white dwarfs5. However, a large group of pulsating stars of intermediate mass-the so-called δ Scuti stars-have rich pulsation spectra for which systematic mode identification has not hitherto been possible6,7. This arises because only a seemingly random subset of possible modes are excited and because rapid rotation tends to spoil regular patterns8-10. Here we report the detection of remarkably regular sequences of high-frequency pulsation modes in 60 intermediate-mass main-sequence stars, which enables definitive mode identification. The space motions of some of these stars indicate that they are members of known associations of young stars, as confirmed by modelling of their pulsation spectra.

An Exploratory Trial of Cognitive-Behavioral vs Client-Centered Therapies for Child-Mother Dyads Bereaved from Terrorism.

The study was an evaluation of Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT; Cohen et al. 2017) with child-caregiver dyads who experienced the death of a loved one from terrorism, using a hybrid efficacy/effectiveness design in which there were no required minimum symptom levels. Forty children ages 4-17 years old whose fathers died in the line of duty on 9/11/2001 and their mothers participated in an RCT comparing TF-CBT and Client-Centered Therapy (CCT). At baseline, mothers' PTSD, depression, and prolonged grief symptoms were highly elevated, whereas children's were at normative levels. Using intent-to-treat analysis, condition-by-time interactions showed significantly greater symptom reduction for mothers receiving CBT than those receiving CCT. For the children, both treatments led to significant symptom improvements.

A Systems-Level Approach to Improving Medication Adherence in Hypertensive Latinos: a Randomized Control Trial.

BACKGROUND: Despite numerous interventions targeting medication adherence in patients with uncontrolled hypertension, practice-based trials in Latino patients are scant. OBJECTIVE: To evaluate the effect of a systems-level adherence intervention, delivered by medical assistants (MAs), versus a comparison condition on medication adherence and blood pressure (BP) in 119 hypertensive Latino patients who were initially non-adherent to their antihypertensive medications. STUDY DESIGN: Randomized control trial. PARTICIPANTS: Patients (50% women; mean age, 61 years) were recruited from April 2013 to August 2015 in a community-based practice in New York. INTERVENTION: Systems-level approach that included an office system component built into the electronic health record and a provider support component consisting of nine MA-delivered health coaching sessions for improving medication adherence. The comparison group received the standard health coaching procedures followed at the clinic. MAIN OUTCOME MEASURES: The primary outcome was rate of medication adherence measured by an electronic monitoring device (EMD) across 6 months. The secondary outcomes were self-reported medication adherence measured by the eight-item Morisky Medication Adherence Scale (MMAS-8) and BP reduction from baseline to 6 months. KEY RESULTS: Adherence as measure by EMD worsened for both groups (p = 0.04) with no between-group difference (- 9.6% intervention and - 6.6% control, p = 0.66). While systolic BP improved in both groups, the difference between groups was not significant (- 6 mmHg in intervention vs. - 2.7 mmHg in control, p = 0.34). In contrast, the intervention group had a greater improvement in self-reported adherence (mean change 1.98 vs. 1.26, p = 0.03) when measured using the MMAS-8. CONCLUSIONS: Among Latinos with poorly controlled BP who were non-adherent to their antihypertensive medications, a systems-level intervention did not improve adherence as measured by EMD nor blood pressure. However, many patients reported challenges to using the EMD. Improvements in self-reported adherence suggest that this measure captures different aspects of adherence behavior than EMD.

The Behaviour of Galactic Cosmic-Ray Intensity During Solar Activity Cycle 24.

We have studied long-term variations of galactic cosmic-ray (GCR) intensity in relation to the sunspot number (SSN) during the most recent solar cycles. This study analyses the time lag between the GCR intensity and SSN, and hysteresis plots of the GCR count rate against SSN for Solar Cycles 20 - 23, to validate a methodology against previous results in the literature, before applying the method to provide a timely update on the behaviour of Cycle 24. Plots of SSN versus GCR show a clear difference between the odd- and even-numbered cycles. Linear and elliptical models have been fit to the data, with the linear fit and elliptical model proving the more suitable model for even- and odd-numbered solar-activity cycles, respectively, in agreement with previous literature. Through the application of these methods for Solar Cycle 24, it has been shown that Cycle 24 experienced a lag of two to four months between the GCR intensity and SSN, and this follows the trend of the preceding activity cycles, albeit with a slightly longer lag than previous even-numbered cycles. It has been shown through the hysteresis analysis that the linear fit is a better representative model for Cycle 24, as the ellipse model does not show a significant improvement, which is also in agreement with previous even-numbered cycles.

Cluster Randomized Clinical Trial of FAITH (Faith-Based Approaches in the Treatment of Hypertension) in Blacks.

BACKGROUND: Therapeutic lifestyle change (TLC) is a recommended treatment for patients with hypertension, but its effectiveness in community-based settings remains untested, particularly in black churches-an influential institution for health promotion in black communities. METHODS AND RESULTS: The FAITH study (Faith-Based Approaches in the Treatment of Hypertension) evaluated the comparative effectiveness of a TLC intervention plus motivational interviewing (MINT) sessions versus health education (HE) alone, on blood pressure (BP) reduction among blacks with uncontrolled hypertension. Data were collected on 373 participants meeting eligibility criteria (self-identification as black, age ≥18 years, self-reported diagnosis of hypertension, and uncontrolled BP [BP ≥140/90 or ≥130/80 mm Hg with diabetes mellitus or chronic kidney disease]) from 32 New York City churches. The MINT-TLC intervention plus motivational interviewing treatment comprised 11 weekly group sessions on TLC plus 3 MINT sessions delivered monthly by lay health advisors. The HE control group received 1 TLC session plus 10 sessions on health topics delivered by local experts. The outcomes were BP reduction at 6 months (primary) and BP control and BP reduction at 9 months (secondary). The sample mean age was 63 years; 76% women, with mean BP of 153/87 mm Hg. Using linear mixed-effects regression models, the MINT-TLC intervention plus motivational interviewing group had a significantly greater systolic BP reduction of 5.79 mm Hg compared with the HE group at 6 months ( P=0.029). The treatment effect on systolic BP persisted at 9 months but had reduced significance (5.21 mm Hg; P=0.068). The between-group differences in diastolic BP reduction (0.41 mm Hg) and mean arterial pressure (2.24 mm Hg) at 6 months were not significant. Although the MINT-TLC intervention plus motivational interviewing group had greater BP control than the HE group at 9 months, the difference was not statistically significant (57.0% versus 48.8%; odds ratio, 1.43; 95% CI, 0.90-2.28). CONCLUSIONS: A community-based lifestyle intervention delivered in churches led to significantly greater reduction in systolic BP in hypertensive blacks compared with HE alone.

Development and Validation of a Measure to Assess Patients' Threat Perceptions in the Emergency Department.

OBJECTIVE: Threat perceptions in the emergency department (ED; e.g., patients' subjective feelings of helplessness or lack of control) during evaluation for an acute coronary syndrome (ACS) are associated with the development of posttraumatic stress disorder (PTSD), and PTSD has been associated with medication nonadherence, cardiac event recurrence, and mortality. This study reports the development and validation of a seven-item measure of ED threat perceptions in English- and Spanish-speaking patients evaluated for ACS. METHODS: Participants were drawn from an observational cohort study of 1,000 patients evaluated for ACS between 2013 and 2016 in a large New York City hospital. Participants reported on threat perceptions in the ED and during inpatient stay (using 12 items previously identified as predictive of PTSD) and reported on cardiac-induced PTSD 1 month postdischarge. Exploratory and confirmatory factor analyses were used to establish the factor structure and test measurement invariance. Validity and reliability were examined, as was the association of ED threat perceptions with cardiac-induced PTSD. RESULTS: Factor analyses identified a seven-item measure of ED threat perceptions (e.g., "I feel helpless," "I am worried that I am going to die") for both English- and Spanish-speaking patients. ED threat perceptions demonstrated convergent validity, correlating with ED stress and ED crowdedness (r = 0.29 and r = 0.14), good internal consistency (α = 0.82), and stability (r = 0.61). Threat perceptions were associated with cardiac-induced acute stress at inpatient and PTSD symptoms at 1 month (r = 0.43 and r = 0.39). CONCLUSIONS: This brief tool assessing ED threat perceptions has clinical utility for providers to identify patients at risk for developing cardiac-induced PTSD and is critical to inform research on whether threat may be modified in-ED to reduce PTSD incidence.

Putative mechanisms Underlying Myocardial infarction onset and Emotions (PUME): a randomised controlled study protocol.

INTRODUCTION: The experience of negative emotions (eg, anger, anxiety and sadness) is associated with an increased short-term risk of incident cardiovascular disease (CVD) events, independent of traditional CVD risk factors. Impairment in endothelial function is one possible biological mechanism which may explain the association between negative emotions and incident CVD events. This laboratory-based, single-blind, randomised controlled experimental study aims to investigate the impact of induced negative emotions including anger, anxiety and sadness on endothelial function. METHODS AND ANALYSIS: In a between-subjects design, 280 healthy participants are randomised to one of four experimental negative emotion inductions: anger, anxiety, sadness or a neutral condition. Endothelium-dependent vasodilation, circulating levels of endothelial cell-derived microparticles and bone marrow-derived endothelial progenitor cells, and indices of nitric oxide inhibition are assessed before and 3, 40, 70 and 100 min after negative emotion induction. Finally, in a subsample of 84 participants, the potential moderating effects of cardiorespiratory fitness and habitual physical activity on the adverse effects of an acute negative emotion on endothelial function are investigated. ETHICS AND DISSEMINATION: This study is conducted in compliance with the Helsinki Declaration and the Columbia University Medical Center Institutional Review Board. The results of the study will be disseminated at several research conferences and as published articles in peer reviewed journals. The study will be implemented and reported in line with the SPIRIT statement. TRIAL REGISTRATION NUMBER: NCT01909895; Pre-results.

Health insurance coverage with or without a nurse-led task shifting strategy for hypertension control: A pragmatic cluster randomized trial in Ghana.

BACKGROUND: Poor access to care and physician shortage are major barriers to hypertension control in sub-Saharan Africa. Implementation of evidence-based systems-level strategies targeted at these barriers are lacking. We conducted a study to evaluate the comparative effectiveness of provision of health insurance coverage (HIC) alone versus a nurse-led task shifting strategy for hypertension control (TASSH) plus HIC on systolic blood pressure (SBP) reduction among patients with uncontrolled hypertension in Ghana. METHODS AND FINDINGS: Using a pragmatic cluster randomized trial, 32 community health centers within Ghana's public healthcare system were randomly assigned to either HIC alone or TASSH + HIC. A total of 757 patients with uncontrolled hypertension were recruited between November 28, 2012, and June 11, 2014, and followed up to October 7, 2016. Both intervention groups received health insurance coverage plus scheduled nurse visits, while TASSH + HIC comprised cardiovascular risk assessment, lifestyle counseling, and initiation/titration of antihypertensive medications for 12 months, delivered by trained nurses within the healthcare system. The primary outcome was change in SBP from baseline to 12 months. Secondary outcomes included lifestyle behaviors and blood pressure control at 12 months and sustainability of SBP reduction at 24 months. Of the 757 patients (389 in the HIC group and 368 in the TASSH + HIC group), 85% had 12-month data available (60% women, mean BP 155.9/89.6 mm Hg). In intention-to-treat analyses adjusted for clustering, the TASSH + HIC group had a greater SBP reduction (-20.4 mm Hg; 95% CI -25.2 to -15.6) than the HIC group (-16.8 mm Hg; 95% CI -19.2 to -15.6), with a statistically significant between-group difference of -3.6 mm Hg (95% CI -6.1 to -0.5; p = 0.021). Blood pressure control improved significantly in both groups (55.2%, 95% CI 50.0% to 60.3%, for the TASSH + HIC group versus 49.9%, 95% CI 44.9% to 54.9%, for the HIC group), with a non-significant between-group difference of 5.2% (95% CI -1.8% to 12.4%; p = 0.29). Lifestyle behaviors did not change appreciably in either group. Twenty-one adverse events were reported (9 and 12 in the TASSH + HIC and HIC groups, respectively). The main study limitation is the lack of cost-effectiveness analysis to determine the additional costs and benefits, if any, of the TASSH + HIC group. CONCLUSIONS: Provision of health insurance coverage plus a nurse-led task shifting strategy was associated with a greater reduction in SBP than provision of health insurance coverage alone, among patients with uncontrolled hypertension in Ghana. Future scale-up of these systems-level strategies for hypertension control in sub-Saharan Africa requires a cost-benefit analysis. TRIAL REGISTRATION: ClinicalTrials.gov NCT01802372.

Evaluation of a Novel Wireless Transmission System for Trauma Ultrasound Examinations From Moving Ambulances.

Objective: To determine if physicians trained in ultrasound interpretation perceive a difference in image quality and usefulness between Extended Focused Assessment with Sonography ultrasound examinations performed at bedside in a hospital vs. by emergency medical technicians minimally trained in medical ultrasound on a moving ambulance and transmitted to the hospital via a novel wireless system. In particular, we sought to demonstrate that useful images could be obtained from patients in less than optimal imaging conditions; that is, while they were in transport. Methods: Emergency medical technicians performed the examinations during transport of blunt trauma patients. Upon patient arrival at the hospital, a bedside Extended Focused Assessment with Sonography examination was performed by a physician. Both examinations were recorded and later reviewed by physicians trained in ultrasound interpretation. Results: Data were collected on 20 blunt trauma patients over a period of 13 mo. Twenty ultrasound-trained physicians blindly compared transmitted vs. bedside images using 11 Questionnaire for User Interaction Satisfaction scales. Four paired samples t-tests were conducted to assess mean differences between ratings for ambulatory and base images. Conclusion: Although there is a slight tendency for the average rating across all subjects and raters to be slightly higher in the base than in the ambulatory condition, none of these differences are statistically significant. These results suggest that the quality of the ambulatory images was viewed as essentially as good as the quality of the base images.

Caregiver Report of Child Symptoms Predicts Attrition in Abuse-Specific Cognitive Behavioral Therapies.

A common critique of empirically supported treatments for abuse-related psychopathology is attrition during critical phases of therapy (i.e., exposure). The goal of this study was to examine whether child and caregiver symptoms were predictive of attrition among families in abuse-specific cognitive-behavioral therapies (CBTs). Children ( N = 104) and their caregivers completed baseline assessments of internalizing symptoms, externalizing problems, and post-traumatic stress disorder (PTSD) and were enrolled in abuse-specific CBTs. Logistic regressions were conducted with baseline symptoms as predictor variables and treatment status (attrition vs. completion) as the criterion variable. Caregiver report of child internalizing symptoms showed the predicted quadratic relation to attrition. Caregiver report of child externalizing symptoms at moderate and high (vs. low) levels was associated with attrition. Child self-report and caregiver self-report of symptoms were not associated with the dyad's attrition. These results underscore the importance of attending to caregivers' initial perceptions of children's symptoms in abuse-specific therapy.

PLANETARY CANDIDATES OBSERVED BY Kepler. VIII. A FULLY AUTOMATED CATALOG WITH MEASURED COMPLETENESS AND RELIABILITY BASED ON DATA RELEASE 25.

We present the Kepler Object of Interest (KOI) catalog of transiting exoplanets based on searching four years of Kepler time series photometry (Data Release 25, Q1-Q17). The catalog contains 8054 KOIs of which 4034 are planet candidates with periods between 0.25 and 632 days. Of these candidates, 219 are new in this catalog and include two new candidates in multi-planet systems (KOI-82.06 and KOI-2926.05), and ten new high-reliability, terrestrial-size, habitable zone candidates. This catalog was created using a tool called the Robovetter which automatically vets the DR25 Threshold Crossing Events (TCEs) found by the Kepler Pipeline (Twicken et al. 2016). Because of this automation, we were also able to vet simulated data sets and therefore measure how well the Robovetter separates those TCEs caused by noise from those caused by low signal-to-noise transits. Because of these measurements we fully expect that this catalog can be used to accurately calculate the frequency of planets out to Kepler's detection limit, which includes temperate, super-Earth size planets around GK dwarf stars in our Galaxy. This paper discusses the Robovetter and the metrics it uses to decide which TCEs are called planet candidates in the DR25 KOI catalog. We also discuss the simulated transits, simulated systematic noise, and simulated astrophysical false positives created in order to characterize the properties of the final catalog. For orbital periods less than 100 d the Robovetter completeness (the fraction of simulated transits that are determined to be planet candidates) across all observed stars is greater than 85%. For the same period range, the catalog reliability (the fraction of candidates that are not due to instrumental or stellar noise) is greater than 98%. However, for low signal-to-noise candidates found between 200 and 500 days, our measurements indicate that the Robovetter is 73.5% complete and 37.2% reliable across all searched stars (or 76.7% complete and 50.5% reliable when considering just the FGK dwarf stars). We describe how the measured completeness and reliability varies with period, signal-to-noise, number of transits, and stellar type. Also, we discuss a value called the disposition score which provides an easy way to select a more reliable, albeit less complete, sample of candidates. The entire KOI catalog, the transit fits using Markov chain Monte Carlo methods, and all of the simulated data used to characterize this catalog are available at the NASA Exoplanet Archive.

Strongest Families™ Managing Our Mood (MOM): a randomized controlled trial of a distance intervention for women with postpartum depression.

The present study investigated whether a distance-delivered intervention could significantly decrease mild to moderate postpartum depression (PPD) in mothers as compared to usual care. Mothers with PPD (n = 62) were randomly assigned to the intervention or standard community care. Participants receiving the intervention followed a 12-session cognitive behavioural informed handbook supplemented with telephone-based coaching support. Diagnostic status and depressive symptoms were assessed at baseline and 3, 6 and 12 months postrandomization. Odds ratios indicated that intervention group participants were 1.5 times as likely to experience diagnostic remission at 3 months (mid-intervention) (p = 0.742), 1.54 times as likely at 6 months (p = 0.696) and 12.5 times as likely at 12 months (p = 0.009). Intervention 'dosage' significantly moderated this effect; for every additional coaching session completed, individuals had a 1.4 times greater chance of showing improvement at 3 and 6 months. Mothers reported high satisfaction with the intervention. Findings suggest positive outcomes at each time point and superior outcomes to the control condition at the long-term follow-up. Caution in interpreting these results is warranted due to small sample size and incomplete data; however, they support further investigation into the use of distance interventions as an accessible and effective solution for women with PPD.

Predictors of quality of life in patients with diabetes mellitus in two tertiary health institutions in Ghana and Nigeria.

BACKGROUND: Patients with chronic diseases such as Type 2 diabetes mellitus (DM) usually have a relatively poor quality of life (QoL), because the cost of care (living expenses and health) or diet restrictions are heavily felt by these patients, and this is of a public health concern. However, limited data on DM QoL exist in Ghana and Nigeria. This makes it imperative for data to be collated in that regard. MATERIALS AND METHODS: We adopted the Strengthening The reporting of observational studies in epidemiology (STROBE) consensus checklist to survey the patients with DM seen at the diabetic clinic at the Department of Medicine of the Korle-Bu Teaching Hospital and University College Hospital, Ibadan, Nigeria. Patients with Type 2 DM aged 40 years and older were recruited by using systematic random sampling method. The World Health Organization Quality of Life-BREF, diabetes empowerment scale, and DM knowledge scale were used to assess QoL, patient empowerment, and knowledge of DM, respectively. The predictors of QoL were determined using multiple linear regression analyses. RESULTS: A total of 198 patients in Ghana and 203 patients in Nigeria completed the survey, with female-to-male ratio being 3:1 and 2:1, respectively. The overall QoL in both countries was relatively low: 56.19 ± 8.23 in Ghana and 64.34 ± 7.34 in Nigeria. In Ghana, significant correlates of higher scores on the QoL scale were medication adherence (P = 0.02) and employment status (P = 0.02). Among patients in Nigeria, employment status (P = 0.02) and DM empowerment (0.03) were significant predictors of QoL in patients with DM. CONCLUSION: Our study revealed an association between a number of psychosocial factors and QoL among patients with DM in Ghana and Nigeria.
