Nonperturbative Second Law of Black Hole Mechanics in Effective Field Theory.

We describe a method for defining dynamical black hole entropy in gravitational effective field theories. The entropy is constructed order by order in derivatives. For any fixed number of derivatives, the entropy satisfies a nonperturbative second law of black hole mechanics if the black hole remains within the regime of validity of effective field theories. In equilibrium the entropy reduces to the Wald entropy. It reduces to the entropy defined by Hollands et al. in theories of vacuum gravity with up to ten derivatives.

Prenatal opioid use as a predictor of postpartum suicide attempts among reproductive-age women enrolled in Oregon Medicaid.

BACKGROUND: The rates of suicide and opioid use disorder (OUD) among pregnant and postpartum women continue to increase. This research characterized OUD and suicide attempts among Medicaid-enrolled perinatal women and examined prenatal OUD diagnosis as a marker for postpartum suicide attempts. METHODS: Data from Oregon birth certificates, Medicaid eligibility and claims files, and hospital discharge records were linked and analyzed. The sample included Oregon Medicaid women aged 15-44 who became pregnant and gave live births between January 2008 and January 2016 (N = 61,481). Key measures included indicators of suicide attempts (separately for any means and opioid poisoning) and OUD diagnosis, separately assessed during pregnancy and the one-year postpartum period. Probit regression was used to examine the overall relationship between prenatal OUD diagnosis and postpartum suicide attempts. A simultaneous equations model was employed to explore the link between prenatal OUD diagnosis and postpartum suicide attempts, mediated by postpartum OUD diagnosis. RESULTS: Thirty-three prenatal suicide attempts by any means were identified. Postpartum suicide attempts were more frequent with 58 attempts, corresponding to a rate of 94.3 attempts per 100,000. Of these attempts, 79% (46 attempts) involved opioid poisoning. A total of 1,799 unique women (4.6% of the sample) were diagnosed with OUD either during pregnancy or one-year postpartum with 53% receiving the diagnosis postpartum. Postpartum suicide attempts by opioid poisoning increased from 55.5 per 100,000 in 2009 to 105.1 per 100,000 in 2016. The rate of prenatal OUD also almost doubled over the same period. Prenatal OUD diagnosis was associated with a 0.15%-point increase in the probability of suicide attempts by opioid poisoning within the first year postpartum. This increase reflects a three-fold increase compared to the rate for women without a prenatal OUD diagnosis. A prenatal OUD diagnosis was significantly associated with an elevated risk of postpartum suicide attempts by opioid poisoning via a postpartum OUD diagnosis. CONCLUSIONS: The risk of suicide attempt by opioid poisoning is elevated for Medicaid-enrolled reproductive-age women during pregnancy and postpartum. Women diagnosed with prenatal OUD may face an increased risk of postpartum suicides attempts involving opioid poisoning.

Validation of a Modified Group-Based Medical Mistrust Scale Among Young Latinx Adults in the United States.

Medical mistrust is an important barrier to accessing health care among Latinx populations in the United States (US). However, research on the validity and reliability of medical mistrust scales is limited. We examined the validity and reliability of a modified bilingual version of the Group-Based Medical Mistrust scale (mGBMMS) among a sample of Latinx adults. Participants included 308 Latinx adults (ages 18-25), who responded in Spanish (n = 134) or English (n = 174). Following feedback from bilingual/bicultural staff during the English-Spanish translation process, we made three changes to the original GBMMS. Validation testing of our 12-item mGBMMS scale included: split-half and internal consistency reliability; discriminant, convergent, and predictive validity; and both exploratory and confirmatory factor analyses. The mGBMMS had good internal consistency (overall sample: Cronbach's α = 0.79; Spanish: Cronbach's α = 0.73; English: Cronbach's α = 0.83). The mGBMMS showed good convergent (moderately correlated with the experiences of discrimination scale, r = 0.46, p < 0.001) and discriminant (weakly correlated with the acculturation scale, r = 0.11, p = 0.06) validity. Split-half reliability was 0.71 (p < 0.001). Exploratory and confirmatory factor analyses found a two-factor solution. The mGBMMS was associated with satisfaction with care (OR = 0.60, 95%CI: 0.42-0.87), a sign of good predictive validity. Findings suggest that the mGBMMS is a valid and reliable scale to utilize among bilingual (Spanish/English) populations in the US. Further validation studies should be considered among Latinx respondents of different ages, backgrounds, languages, and US regions.

Altered lateralization of the cingulum in deployment-related traumatic brain injury: An ENIGMA military-relevant brain injury study.

Traumatic brain injury (TBI) in military populations can cause disruptions in brain structure and function, along with cognitive and psychological dysfunction. Diffusion magnetic resonance imaging (dMRI) can detect alterations in white matter (WM) microstructure, but few studies have examined brain asymmetry. Examining asymmetry in large samples may increase sensitivity to detect heterogeneous areas of WM alteration in mild TBI. Through the Enhancing Neuroimaging Genetics Through Meta-Analysis Military-Relevant Brain Injury working group, we conducted a mega-analysis of neuroimaging and clinical data from 16 cohorts of Active Duty Service Members and Veterans (n = 2598). dMRI data were processed together along with harmonized demographic, injury, psychiatric, and cognitive measures. Fractional anisotropy in the cingulum showed greater asymmetry in individuals with deployment-related TBI, driven by greater left lateralization in TBI. Results remained significant after accounting for potentially confounding variables including posttraumatic stress disorder, depression, and handedness, and were driven primarily by individuals whose worst TBI occurred before age 40. Alterations in the cingulum were also associated with slower processing speed and poorer set shifting. The results indicate an enhancement of the natural left laterality of the cingulum, possibly due to vulnerability of the nondominant hemisphere or compensatory mechanisms in the dominant hemisphere. The cingulum is one of the last WM tracts to mature, reaching peak FA around 42 years old. This effect was primarily detected in individuals whose worst injury occurred before age 40, suggesting that the protracted development of the cingulum may lead to increased vulnerability to insults, such as TBI.

Novel Psychiatric Disorder 6 Months After Traumatic Brain Injury in Children and Adolescents.

OBJECTIVE: To investigate the factors predictive of novel psychiatric disorders in the interval 0-6 months following traumatic brain injury (TBI). METHODS: Children ages 5-14 years consecutively hospitalized for mild to severe TBI at five hospitals were recruited. Participants were evaluated at baseline (soon after injury) for pre-injury characteristics including psychiatric disorders, socioeconomic status (SES), psychosocial adversity, family function, family psychiatric history, and adaptive function. In addition to the psychosocial variables, injury severity and lesion location detected with acquisition of a research MRI were measured to develop a biopsychosocial predictive model for development of novel psychiatric disorders. Psychiatric outcome, including occurrence of a novel psychiatric disorder, was assessed 6 months after the injury. RESULTS: The recruited sample numbered 177 children, and 141 children (80%) returned for the six-month assessment. Of the 141 children, 58 (41%) developed a novel psychiatric disorder. In univariable analyses, novel psychiatric disorder was significantly associated with lower SES, higher psychosocial adversity, and lesions in frontal lobe locations, such as frontal white matter, superior frontal gyrus, inferior frontal gyrus, and orbital gyrus. Multivariable analyses found that novel psychiatric disorder was independently and significantly associated with frontal-lobe white matter, superior frontal gyrus, and orbital gyrus lesions. CONCLUSION: The results demonstrate that occurrence of novel psychiatric disorders following pediatric TBI requiring hospitalization is common and has identifiable psychosocial and specific biological predictors. However, only the lesion predictors were independently related to this adverse psychiatric outcome.

The prevalence of anxiety disorders in dermatology outpatients: A systematic review and meta-analysis.

Anxiety is common in those with medical conditions and has significant impacts on mental well-being as well as physical health outcomes. While several systematic reviews have examined the prevalence of anxiety in specific dermatological conditions, no reviews have examined the prevalence across the entire dermatology outpatient setting. This systematic review aims to provide an overview to dermatologists of the prevalence of, and trends in, anxiety in their outpatient clinics. As such, prevalence of anxiety in dermatology outpatient clinics was examined, and variations across type of anxiety and dermatological conditions were assessed. A search of PubMed, Embase, Cochrane and PsycINFO was conducted for studies that assessed anxiety prevalence in dermatology outpatients, with the last search conducted on 7 September 2022. Results underwent title/abstract and full-text screening, followed by data extraction. Studies of patients 16 years and older and representative of dermatology clinics were included. Risk of bias was assessed using Joanna Briggs Institute Critical Appraisal Checklist. Meta-analysis was conducted using CMA software, and subgroup analysis was conducted on relevant variables. 5423 studies were identified, and 32 included, with a total n = 12,812 participants. Under the random effects model, prevalence was estimated at 26.7% (95%CI 22.4-31.4; 95%PI 9.7-55.4). Subgroup analysis revealed a higher prevalence among studies of psoriasis patients than general dermatology studies. Estimates of prevalence were higher when assessed via self-report screening than diagnostic interview. Anxiety occurred frequently among dermatology outpatients, especially psoriasis outpatients, at a higher rate than common estimates of prevalence in the general population. Given the effect of anxiety on patient outcomes and well-being, dermatologists are encouraged to consider how anxiety may impact patients in their clinic, and how they can best identify patients with anxiety and subsequently support them.

Comparing post-traumatic stress severity in professional and volunteer Australian firefighters.

BACKGROUND: While extensive research has highlighted increased risk for post-traumatic stress disorder (PTSD) in firefighters, previous research has yielded mixed results regarding the role of work status (professional versus volunteer) in the development of psychopathological symptoms. AIMS: To explore the predictive strength of work status on PTSD or post-traumatic stress symptom severity in a large sample of professional (PFFs) and volunteer (VFFs) Australian firefighters exposed to operational work-related trauma. METHODS: The stratified random sample comprised 1317 PFFs (n = 1148 (87%) males and 13%, n = 169 (13%) females) and 898 VFFs (n = 744 (83%) males and n = 154 (17%) females) who reported having experienced trauma while working or volunteering. Participants completed demographic, health and work-related questions and mental health measures of stress, trauma, PTSD, social support and use of mental health prevention programmes. RESULTS: The results revealed a significant relationship between work status and PTSD, with PFFs reporting higher levels of PTSD symptom severity compared to VFFs. This association persisted after controlling for demographics, health, stress away from work, social support and use of organizational mental health support programmes (debriefing and face-to-face training for mental and physical self-care). CONCLUSIONS: This study suggests the importance of work status in PTSD amongst Australian firefighters exposed to operational trauma. Future research is needed to substantiate our findings and examine why PFFs may be more prone to developing PTSD. Implications for the provision of mental health programmes offered by fire organizations to their members are discussed.

Common mental disorder and suicidality among doctors: differences by specialty.

BACKGROUND: Common mental disorders (CMDs) and suicidal ideation (SI) are prevalent among doctors, yet limited evidence exists investigating the relationship of specialty area to these outcomes. AIMS: This study aimed to determine the prevalence of likely CMD and SI among doctors and to investigate whether likelihood of these outcomes varied by area of medical specialty. METHODS: A secondary analysis of a representative national survey of 12,252 Australian doctors was conducted. Demographic and work-related variables, SI and CMD (GHQ-28), were assessed among doctors (n = 7037; 57%) working in a range of specialty areas. Logistic regression was used to examine the association between specialty and mental health outcomes in unadjusted and adjusted models. RESULTS: Almost one-quarter of doctors (n = 1560; 23%) reported symptom levels indicating likely CMD whilst 9% (n = 667) reported SI in the last year. Doctors in surgery (adjusted odds ratio [OR] = 0.73, 95% confidence interval [CI] 0.54-0.97, P = 0.03) were at significantly lower risk of CMD than General Practitioners (GPs), whilst doctors in anaesthetics (adjusted OR = 1.45; 95% CI 1.09-1.93, P = 0.01) and paediatrics (adjusted OR = 1.88; 95% CI 1.02-3.47, P = 0.04) were at significantly higher risk of experiencing SI compared to GPs after accounting for confounders. CONCLUSIONS: Results demonstrated that doctors in Australia working in certain specialties, specifically anaesthetics and paediatrics, were at significantly greater risk of suicidal ideation compared to GPs after accounting for confounders. Interventions to address CMD and SI among doctors in all specialties remain urgently needed.

Frequency and Intensity of Premonitory Urges-to-Tic in Tourette Syndrome Is Associated With Supplementary Motor Area GABA+ Levels.

BACKGROUND: Individuals with Tourette syndrome (TS) often report that they express tics as a means of alleviating the experience of unpleasant sensations. These sensations are perceived as an urge to act and are referred to as premonitory urges. Premonitory urges have been the focus of recent efforts to develop interventions to reduce tic expression in those with TS. OBJECTIVE: The aim of this study was to examine the contribution of brain γ-aminobutyric acid (GABA) and glutamate levels of the right primary sensorimotor cortex (SM1), supplementary motor area (SMA), and insular cortex (insula) to tic and urge severity in children with TS. METHODS: Edited magnetic resonance spectroscopy was used to assess GABA+ (GABA + macromolecules) and Glx (glutamate + glutamine) of the right SM1, SMA, and insula in 68 children with TS (MAge = 10.59, SDAge = 1.33) and 41 typically developing control subjects (MAge = 10.26, SDAge = 2.21). We first compared GABA+ and Glx levels of these brain regions between groups. We then explored the association between regional GABA+ and Glx levels with urge and tic severity. RESULTS: GABA+ and Glx of the right SM1, SMA, and insula were comparable between the children with TS and typically developing control subjects. In children with TS, lower levels of SMA GABA+ were associated with more severe and more frequent premonitory urges. Neither GABA+ nor Glx levels were associated with tic severity. CONCLUSIONS: These results broadly support the role of GABAergic neurotransmission within the SMA in the experience of premonitory urges in children with TS. © 2021 International Parkinson and Movement Disorder Society.

The Role of the Cerebellum in Repetitive Behavior Across Species: Childhood Stereotypies and Deer Mice.

Recent studies suggest that the cerebellum may have a significant role in repetitive behaviors. In primary complex motor stereotypies, typically developing children have repetitive movements usually involving rhythmic flapping/waving arm/hand movements. Similarly, the deer mouse animal model exhibits inherited repetitive behaviors, with increased frequencies of spontaneous jumping and rearing. In this study, data from both children with motor stereotypies and deer mice were used to investigate the role of the cerebellum in repetitive behaviors. The 3.0-T MRI volumetric imaging of the cerebellum was obtained in 20 children with primary complex motor stereotypies and 20 healthy controls. In deer mice, cerebellar volume (n = 7/group) and cell counts (n = 9/group) were compared between high- and low-activity animals. Levels of cerebellar neurotransmitters were also determined via HPLC (n = 10/group). In children with stereotypies, (a) there were a statistically significant reduction (compared to controls) in the white matter volume of the posterior cerebellar lobule VI-VII that negatively correlated with motor control and (b) an 8% increase in the anterior vermis gray matter that positively correlated with motor Stereotypy Severity Scores (SSS). In deer mice, (a) there was a significant increase in the volume of the anterior vermal granular cell layer that was associated with higher activity and (b) dentate nucleus cell counts were higher in high activity animals. Similar increases in volume were observed in anterior vermis in children with stereotypies and a deer mouse model of repetitive behaviors. These preliminary findings support the need for further investigation of the cerebellum in repetitive behaviors.

Prevalence and Risk Factors of PrEP Use Stigma Among Adolescent Girls and Young Women in Johannesburg, South Africa and Mwanza, Tanzania Participating in the EMPOWER Trial.

Adolescent girls and young women (AGYW) in sub-Saharan Africa may benefit from pre-exposure prophylaxis (PrEP), yet stigma may limit PrEP acceptance and continuation. We examined factors associated with PrEP use stigma among 307 participants of the EMPOWER trial (2016-2018), an unblinded randomized controlled trial among HIV-negative, AGYW, aged 16-24, in South Africa and Tanzania. The 6-item, brief-PrEP use stigma scale (B-PSS) had high internal reliability. At the end of the trial, 34.2% of study participants reported any PrEP use stigma. Three latent classes were observed, reflecting low (46.9%), medium (31.9%), and high (21.2%) reported PrEP use stigma. Disclosure of PrEP use to sexual partner and belief that PrEP prevents HIV were associated with less reported PrEP use stigma. Conversely, participants who reported fear and shame about people living with HIV were more likely to report PrEP use stigma. Our validated tool and findings will enable practitioners to identify AGYW at high risk of PrEP use stigma who may benefit from additional support.Pan African clinical trials registry PACTR202006754762723, 5 April 2020, retrospectively registered.

Novel Oppositional Defiant Disorder 12 Months After Traumatic Brain Injury in Children and Adolescents.

OBJECTIVE: The investigators examined the factors predictive of novel oppositional defiant disorder in the 6-12 months following traumatic brain injury (TBI). METHODS: Children ages 5-14 years old who experienced a TBI were recruited from consecutive admissions to five hospitals. Participants were evaluated soon after injury (baseline) for preinjury characteristics, including psychiatric disorders, adaptive function, family function, psychosocial adversity, family psychiatric history, socioeconomic status, and injury severity, to develop a biopsychosocial predictive model for development of novel oppositional defiant disorder. MRI analyses were conducted to examine potential brain lesions. Psychiatric outcome, including that of novel oppositional defiant disorder, was assessed 12 months after injury. RESULTS: Although 177 children were recruited for the study, 120 children without preinjury oppositional defiant disorder, conduct disorder, or disruptive behavior disorder not otherwise specified (DBD NOS) returned for the 12-month assessment. Of these 120 children, seven (5.8%) exhibited novel oppositional defiant disorder, and none developed conduct disorder or DBD NOS in the 6-12 months postinjury. Novel oppositional defiant disorder was significantly associated with lower socioeconomic status, higher psychosocial adversity, and lower preinjury adaptive functioning. CONCLUSIONS: These results demonstrate that novel oppositional defiant disorder following TBI selectively and negatively affects an identifiable group of children. Both proximal (preinjury adaptive function) and distal (socioeconomic status and psychosocial adversity) psychosocial variables significantly increase risk for this outcome.

Novel Oppositional Defiant Disorder 6 Months After Traumatic Brain Injury in Children and Adolescents.

OBJECTIVE: The investigators aimed to assess predictive factors of novel oppositional defiant disorder (ODD) among children and adolescents in the first 6 months following traumatic brain injury (TBI). METHODS: Children ages 5-14 years who experienced a TBI were recruited from consecutive admissions to five hospitals. Testing of a biopsychosocial model that may elucidate the development of novel ODD included assessment soon after injury (baseline) of preinjury characteristics, including psychiatric disorders, adaptive function, family function, psychosocial adversity, family psychiatric history, socioeconomic status, injury severity, and postinjury processing speed (which may be a proxy for brain injury). MRI analyses were also conducted to examine potential brain lesions. Psychiatric outcome, including that of novel ODD, was assessed 6 months after the injury. RESULTS: A total of 177 children and adolescents were recruited for the study, and 134 who were without preinjury ODD, conduct disorder, or disruptive behavior disorder not otherwise specified (DBD NOS) returned for the 6-month assessment. Of those who returned 6 months postinjury, 11 (8.2%) developed novel ODD, and none developed novel conduct disorder or DBD NOS. Novel ODD was significantly associated with socioeconomic status, preinjury family functioning, psychosocial adversity, and processing speed. CONCLUSIONS: These findings show that an important minority of children with TBI developed ODD. Psychosocial and injury-related variables, including socioeconomic status, lower family function, psychosocial adversity, and processing speed, significantly increase risk for this outcome.

Clinical outcomes of a beveled tip, ultra-high speed, 25-gauge pars plana vitrectomy system.

OBJECTIVE: To report the clinical outcomes of a 25-gauge, beveled-tip, 10,000 cuts-per-minute (cpm) microincisional vitrectomy surgery (MIVS) system. METHODS: Prospective case series of eyes undergoing primary pars plana vitrectomy (PPV) for common vitreoretinal indications. Main outcome measures were: rate of achieving surgical objectives, operative times, number of surgical steps, use of ancillary instruments, corrected distance visual acuity (CDVA), and adverse events (AE). RESULTS: The surgical objectives were achieved in all eyes. Mean total operative time (TOT), core, shave and total vitrectomy times were 1891 ± 890, 204 ± 120, 330 ± 320, 534 ± 389 s, respectively. Mean number of surgical steps was 4.3 ± 1.5. Mean number of ancillary instruments used was 4.5 ± 1.9. Mean CDVA improved by 0.53 ± 0.56 logMAR units (P < 0.001) 3 months postoperatively. AE included elevated IOP (8%), hypotony (6%), and re-detachment (2%). Majority (82%) had no postoperative discomfort. The number of surgical steps demonstrated a positive correlation with TOT (p < 0.05), number of ancillary instruments used (p < 0.05), and postoperative Day 1 IOP (p < 0.05). The number of times ancillary instrumentation was used demonstrated a positive correlation with TOT (p < 0.05). CONCLUSION: Beveled-tip, 10,000 cpm MIVS system effectively and safely performs common VR procedures of varying complexity and may reduce operative times and use of ancillary instrumentation.

Experiences of discrimination and endorsement of HIV/AIDS conspiracy beliefs: exploring difference among a sample of Latino, Black, and White young adults.

Racial/ethnic discrimination and HIV/AIDS conspiracy beliefs may contribute to disparities in use and satisfaction with healthcare services. Previous studies that examined racial/ethnic experiences of everyday discrimination (EOD), health care discrimination (HCD), and HIV/AIDS conspiracy beliefs (HCB) focused primarily on African Americans with few studies focusing on Latinos. This study used data from in-person structured interviews with 450 Latino, Black, and White young adults from East Los Angeles, California. Multivariable models, adjusting for all demographic covariates, investigated if race/ethnicity and gender were associated with EOD and HCD and endorsing HCB, and if the associations between race/ethnicity and discriminations and HCB varied by gender. Blacks and Latinos reported more experiences of EOD and HCD in almost all forms and endorsed more HIV/AIDS conspiracy beliefs compared to Whites. Additionally, Black and Latino men reported stronger feelings of EOD than their female counterparts. More reports of experiences of HCD and endorsement of HCB beliefs were found for Blacks, Latinos, and participants with children compared to their counterparts. This study contributes to a growing understanding of how different racial/ethnic groups experience discrimination across various settings and everyday activities and their endorsement of HIV/AIDS conspiracy beliefs. The field of Public Health must address the problems of racism and discrimination similar to any other toxic pathogen. In so doing, Public Health becomes proactive in its efforts to mitigate the effects of racial discriminations on population health.

The impact of depression, anxiety and comorbidity on occupational outcomes.

BACKGROUND: Anxiety and depression account for considerable cost to organizations, driven by both presenteeism (reduced performance due to attending work while ill) and absenteeism. Most research has focused on the impact of depression, with less attention given to anxiety and comorbid presentations. AIMS: To explore the cross-sectional relationship between depression and anxiety (individually and comorbidly) on workplace performance and sickness absence. METHODS: As part of a larger study to evaluate a mental health app, 4953 working Australians were recruited. Participants completed in-app assessment including demographic questions, the Patient Health Questionnaire-9, two-item Generalized Anxiety Disorder and questions from the World Health Organization Health and Work Performance Questionnaire. Cut-off scores were used to establish probable cases of depression alone, anxiety alone and comorbidity. RESULTS: Of the total sample, 7% met cut-off for depression only, 13% anxiety only, while 16% were comorbid. Those with comorbidity reported greater symptom severity, poorer work performance and more sickness absence compared to all other groups. Presenteeism and absenteeism were significantly worse in those with depression only and anxiety only compared to those with non-clinical symptom levels. Although those with depression alone tended to have poorer outcomes than the anxiety-only group, when sample prevalence rates were considered, the impact on presenteeism was comparable. CONCLUSIONS: Workplace functioning is heavily impacted by depression and anxiety both independently and where they co-occur. While comorbidity and more severe depression presentations stand out as impairing, workplace interventions should also prioritize targeting of anxiety disorders (and associated presenteeism) given their high population prevalence.

Dyadic support across contraceptive decision-making among young adult breast cancer survivors and their partners.

OBJECTIVE: The purpose of this study is to explore the role of dyadic support across the contraceptive decision-making process between young adult breast cancer (YABC) survivors and their partners. RESEARCH APPROACH: Semi-structured interviews with YABC survivors and their partners. PARTICIPANTS: Twenty-five young adult breast cancer survivors and their partners (n = 50). Survivors reported an average age of 36.9 years (SD = 4.30) and the majority self-identified as white (86.2%). METHODOLOGICAL APPROACH: Thematic analysis approach with dyads as the primary unit of analysis, guided by the dyadic decision-making framework and the Theory of Gender and Power. RESULTS: Perceived lack of contraceptive options due to a history of hormone-sensitive cancer, perceived infertility, and contraception as a result of cancer treatment (e.g., hysterectomy) contributed to the contraceptive decision context for survivors and their partners. Contraceptive support varied across couples depending on the cancer-specific context, where communication, sharing responsibility, and respecting bodily autonomy revealed as supportive behaviors. Other social influences including survivors' desire to conceive biologically and family planning desires also related to partner supportive behaviors. INTERPRETATIONS: YABC survivors face specific challenges to contraceptive decision-making where partners can offer supportive behaviors. Health care providers can also support couples by engaging in triadic communication about contraception and family planning. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS OR POLICY: Psychosocial providers can support couples by encouraging them to talk together about contraception and highlighting the importance of triadic communication with a healthcare provider to support shared decision-making and alignment of contraceptive decisions with family planning desires.

Impact of Medicaid expansion in Oregon on access to prenatal care.

Medicaid expansion under the Patient Protection and Affordable Care Act (ACA) has the potential to improve reproductive health by allowing low-income women access to healthcare before and early in pregnancy. The aim of this study was to examine the effects of Oregon's Medicaid expansion on timely and adequate prenatal care. We included live births in Oregon from 2012 to 2015 and used individually-linked birth certificate and Medicaid eligibility data. Outcomes were receipt of first trimester prenatal care and receipt of adequate prenatal care. We also assessed Medicaid enrollment one month prior to pregnancy. We estimated the overall effect of Medicaid expansion on prenatal care utilization using probit regression models. Additionally, we assessed the impact of Medicaid expansion on prenatal care utilization via pre-pregnancy Medicaid enrollment using bivariate probit models. Overall, receipt of first trimester prenatal care increased post-expansion by 1.5 percentage points (p < 0.01) after expansion. Receipt of adequate prenatal care also increased significantly post-expansion with an incremental increase of 2.8 percentage points (p < 0.001). Pre-pregnancy Medicaid enrollment increased following Medicaid expansion (ß = 0.55, p < 0.001) and was associated with both timely (ß = 0.48, p < 0.001) and adequate receipt of prenatal care (ß = 0.14, p < 0.001). Using two years of post-ACA data we found that Medicaid expansion had significant positive associations with Medicaid enrollment prior to pregnancy, which subsequently increased receipt of timely and adequate prenatal care. Our study provides evidence that expanding Medicaid has positive effects on women's use of healthcare.

Risk factors for decline in cognitive performance following deployment-related mild traumatic brain injury: A preliminary report.

Thorough identification of risk factors for delayed decline in cognitive performance following combat-related mild traumatic brain injury (mTBI) is important for guiding comprehensive post-deployment rehabilitation. In a sample of veterans who reported at least one deployment-related mTBI, preliminary results indicate that factors including a history of loss of consciousness over 1 min, current obesity and hypertension, and Black race were more prevalent in those with decreased scores on a measure of memory function. These factors should be considered by clinicians and researchers working with current and former military personnel.
