- Abstract
BACKGROUND: A key mechanism thought to underlie Posttraumatic Stress Disorder (PTSD) is enhanced emotional memory consolidation. Recent evidence in healthy controls revealed that women have greater negative memory consolidation following stress relative to men. This study examined emotional memory consolidation in women and men with PTSD, and in trauma-exposed and non-trauma controls to test the hypothesis that emotionally negative memory consolidation would be greater in women with PTSD. METHOD: One hundred and forty-seven men and women (47 with PTSD, 49 trauma-exposed controls, and 51 non-trauma controls) completed an emotional memory task where they looked at negative, neutral and positive images from the International Affective Picture System (IAPS). Delayed recall and an intrusive memory diary were completed two days later. RESULTS: Women displayed greater recall, and reported more negative intrusive memories than men. A gender x group interaction effect showed that both women with PTSD and trauma-exposed women reported more intrusive memories than women without trauma exposure or men. CONCLUSION: This study provided preliminary evidence of sex differences in intrusive memories in those with PTSD as well as those with a history of trauma exposure. Future research should include measures of sex hormones to further examine sex differences on memory consolidation in the context of trauma exposure and PTSD.

- Abstract
BACKGROUND: Prior research has demonstrated that time-of-day may play an important role in the extinction of conditioned fear, with extinction better learned earlier in the day rather than later. Impaired fear extinction memory is widely considered a key mechanism of posttraumatic stress disorder (PTSD). The relationship between fear extinction and PTSD symptoms may be moderated by hours-since-waking. METHOD: In the present experiment, we examined whether hours-since-waking would moderate fear extinction learning ability in a clinical PTSD sample (n = 15), compared to trauma-exposed (n = 33) and nonexposed controls (n = 22). Participants completed a standardized differential fear conditioning and extinction paradigm, providing skin conductance response measures to quantify conditioned responding. RESULTS: Mixed-model analysis of variance revealed a PTSD-specific impairment in extinction learning ability in the late extinction phase. A moderation analysis showed that hours-since-waking was a significant moderator of the relationship between impaired late extinction and PTSD symptoms. Specifically, we found that participants with higher PTSD symptoms demonstrated poorer fear extinction learning ability as they were awake for longer. CONCLUSIONS: The results of the current study add to a growing literature indicating deficits in fear extinction learning in PTSD samples, compared to trauma-exposed and nonexposed controls. These results support previous findings that fear extinction is impaired later in the day, and extends this to a clinical sample, suggesting that exposure-therapy may be optimized by scheduling sessions in the morning.

BackgroundHuman papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the US, responsible for cervical cancer and increased risk of Human Immunodeficiency Virus (HIV) acquisition. Despite an effective HPV vaccine, women's HPV vaccination coverage and rates remain far below desired levels. This study aimed to evaluate HPV knowledge, attitudes, and vaccination practices as well as factors associated with HPV vaccination among women of reproductive age living in Miami, Florida, a Southern US city with a high incidence of STIs and low HPV vaccination coverage.MethodsFrom April to June 2022, 100 HIV-negative, cisgender, sexually active women aged 18-45 years were recruited from the Miami community. Participants completed validated questionnaires using REDCap© electronic surveys, assessing socio-demographics and sexual behaviors; HPV knowledge, screening, vaccination practices; barriers and motivators to HPV vaccination. A cumulative HPV knowledge score (HPV score) was generated. Factors associated with HPV vaccination were analyzed by Chi-square, Fisher's exact test, studentized t-test, and multivariate logistic regression (MLR).ResultsA total of 100 participants were enrolled, and 84 who knew their vaccination status were included in the analysis. Of these, 43 reported receiving at least 1 HPV vaccine dose (vaccinated group) and 41 reported never being vaccinated (unvaccinated group). Mean age was 24.7 (SD 4.03) years for the vaccinated group and 31.4 (SD 8.33) for the unvaccinated group. Mean HPV score was 18.9/29 (SD 6.05) for the vaccinated group and 9.1/29 (SD 8.82) for the unvaccinated group. Amongst vaccinated participants, 76.74% reported a history of HPV/Pap smear screening vs 87.80% in the unvaccinated group. Barriers to HPV vaccination included: 14.6% low-risk perception, 29.3% healthcare barriers, and 46.3% vaccine hesitancy and personal beliefs. Motivators t HPV vaccination included: risk perception and vaccine beliefs (71.42%), healthcare-related (60.71%) and social motivators (55.95%). In the first MLR, one-point increases in HPV score were significantly associated with higher odds of HPV vaccination until an HPV score of 16, and a one-year increase in age was associated with a 16% lower odds of HPV vaccination (aOR = 0.84, 95% CI [0.72, 0.99]; p = 0.035). Contraception use was also associated with HPV vaccination (aOR 8.36 (95% CI [1.41, 49.62]; p = 0.020). Race, ethnicity, college education status, and number of sexual partners were not significant predictors of HPV vaccination. In the second MLR evaluating vaccination motivators as predictors of HPV vaccination, we found that individuals who were motivated by healthcare had 3.03 (95% CI [1.02, 9.00]; p = 0.046) times the odds of HPV vaccination compared to individuals without healthcare-related motivators.ConclusionFindings suggest suboptimal HPV knowledge and low vaccination rates among women of reproductive age. Public health efforts should focus on increasing basic HPV knowledge among women with little-to-no HPV knowledge to increase vaccine uptake.

- Abstract
Background Other than aspirin, there are few oral antithrombotic treatments with proven efficacy in patients with acute coronary syndrome. In this report, we present the rationale, design and baseline characteristics of the Clopidogrel in Unstable angina to prevent Recurrent ischaemic Events (CURE) trial, which includes a meta-analysis of the effects of thienopyridines in patients with vascular disease. Methods and Results Combined data from randomized trials of thienopyrindines in patients with atherosclerotic disease demonstrated a 29% reduction in vascular events when compared with placebo/control (n=2392) (OR 0.71, 95% CI 0.58-0.86, P=0.0006) and a 10% reduction in vascular events when compared with aspirin (n=22 254) (OR 0.91, 95% Cl 0.84-0.99, P=0.039). Similarly, randomized trials of aspirin plus thienopyridines in patients undergoing intracoronary stenting, demonstrated marked benefit of aspirin plus ticlopidine in reducing death or myocardial infarction compared with aspirin alone (OR 0.23, 95% CI 0.11-0.49, P=0.0001) or aspirin plus warfarin (OR 0.51, 95% CI 0.33-0.78, P=0.002). Whether these benefits extend to the much larger population of patients with acute coronary syndrome is unknown. CURE is an international, randomized, double-blind trial, in which patients with acute coronary syndrome will be randomized to receive either a bolus dose of clopidogrel (300 mg) followed by 75 mg per day for 3-12 months, or matching placebo. Both groups will receive aspirin. The co-primary efficacy end-points of CURE are: (1) the composite of cardiovascular death, myocardial infarction or stroke; and (2) the composite of cardiovascular death, myocardial infarction, stroke or refractory ischaemia. CURE will recruit approximately 12 500 patients with acute coronary syndrome (from 28 countries) and its power to detect moderate treatment benefits will be in the region of 80-90%, while maintaining an overall type I error (a) of 0.05. The baseline characteristics of the study population are consistent with at least a moderate risk group of patients with acute coronary syndrome. Conclusions Randomized trials of thienopyridines in patients with vascular disease demonstrate that thienopyridines are effective in reducing vascular events when compared with placebo/control or aspirin, as well as when used in combination with aspirin in patients undergoing intracoronary stent implantation. The CURE trial is a large international study to determine if acute and longterm treatment with the combination of clopidogrel and aspirin is superior to aspirin alone in patients with acute coronary syndrome.

Abstract Background Milkability is a complex trait that is characterized by milk flow traits including average milk flow rate, maximum milk flow rate and total milking time. Milkability has long been recognized as an economically important trait that can be improved through selection. By improving milkability, management costs of milking decrease through reduced labor and improved efficiency of the automatic milking system, which has been identified as an important factor affecting net profit. The objective of this study was to identify markers associated with electronically measured milk flow traits, in the Italian Brown Swiss population that could potentially improve selection based on genomic predictions. Results Sires (n = 1351) of cows with milk flow information were genotyped for 33,074 single nucleotide polymorphism (SNP) markers distributed across 29 Bos taurus autosomes (BTA). Among the six milk flow traits collected, ascending time, time of plateau, descending time, total milking time, maximum milk flow and average milk flow, there were 6,929 (time of plateau) to 14,585 (maximum milk flow) significant SNP markers identified for each trait across all BTA. Unique regions were found for each of the 6 traits providing evidence that each individual milk flow trait offers distinct genetic information about milk flow. This study was also successful in identifying functional processes and genes associated with SNPs that influences milk flow. Conclusions In addition to verifying the presence of previously identified milking speed quantitative trait loci (QTL) within the Italian Brown Swiss population, this study revealed a number of genomic regions associated with milk flow traits that have never been reported as milking speed QTL. While several of these regions were not associated with a known gene or QTL, a number of regions were associated with QTL that have been formerly reported as regions associated with somatic cell count, somatic cell score and udder morphometrics. This provides further evidence of the complexity of milk flow traits and the underlying relationship it has with other economically important traits for dairy cattle. Improved understanding of the overall milking pattern will aid in identification of cows with lower management costs and improved udder health.

Abstract Background Milkability, primarily evaluated by measurements of milking speed and time, has an economic impact in milk production of dairy cattle. Recently the Italian Brown Swiss Breeders Association has included milking speed in genetic evaluations. The main objective of this study was to investigate the possibility of implementing genomic selection for milk flow traits in the Italian Brown Swiss population and thereby evaluate the potential of genomic selection for novel traits in medium-sized populations. Predicted breeding values and reliabilities based on genomic information were compared with those obtained from traditional breeding values. Methods Milk flow measures for total milking time, ascending time, time of plateau, descending time, average milk flow and maximum milk flow were collected on 37 213 Italian Brown Swiss cows. Breeding values for genotyped sires (n = 1351) were obtained from standard BLUP and genome-enhanced breeding value techniques utilizing two-stage and single-step methods. Reliabilities from a validation dataset were estimated and used to compare accuracies obtained from parental averages with genome-enhanced predictions. Results Genome-enhanced breeding values evaluated using two-stage methods had similar reliabilities with values ranging from 0.34 to 0.49 for the different traits. Across two-stage methods, the average increase in reliability from parental average was approximately 0.17 for all traits, with the exception of descending time, for which reliability increased to 0.11. Combining genomic and pedigree information in a single-step produced the largest increases in reliability over parent averages: 0.20, 0.24, 0.21, 0.14, 0.20 and 0.21 for total milking time, ascending time, time of plateau, descending time, average milk flow and maximum milk flow, respectively. Conclusions Using genomic models increased the accuracy of prediction compared to traditional BLUP methods. Our results show that, among the methods used to predict genome-enhanced breeding values, the single-step method was the most successful at increasing the reliability for most traits. The single-step method takes advantage of all the data available, including phenotypes from non-genotyped animals, and can easily be incorporated into current breeding evaluations.

- Abstract
Background: Resuscitative thoracotomies are a time-sensitive emergency surgical procedure with an immediate risk of mortality. We hypothesize that a high-fidelity whole-body donor simulation model, referred to as a Knowledge Donor (KD), with mechanical lung ventilation and expired human blood perfusion could increase learner confidence in performing this critical procedure., Methods: General surgery residents and faculty were invited to participate in KD training. Surveys were collected to track participation and confidence., Results: Simulated resuscitative thoracotomies were performed involving PGY levels I-IV. Mean confidence was highest for residents with both KD and Live Patient experience (5.6 ± 1.7), followed by Live Patient only (4.3 ± 2.5), and KD only (2.6 ± 1.3). The mean confidence rating for residents with neither training opportunity was 1.4 ± 1.0., Conclusions: The KD platform is a hyper-realistic training modality that closely replicates live surgery. This platform allows residents to practice complex surgical procedures in a safe environment, without risking patient safety. This pilot program yielded early results in improving resident procedural confidence for high-risk surgical procedures, specifically resuscitative thoracotomies., Competing Interests: Declaration of competing interest All authors declare they do not have any competing interests that influenced the work reported in this article., (Copyright © 2024 Elsevier Inc.

- Abstract
Background: The MANTA vascular closure device (VCD) represents a novel approach to achieving hemostasis after large-bore femoral access procedures. Numerous clinical studies have evaluated the efficacy of the MANTA device across a range of patient populations undergoing different procedures. However, there is still a paucity of data available concerning the use of MANTA devices in aiding the decannulation of venoarterial extracorporeal membrane oxygenation (VA-ECMO)., Aim: To present our single-center experience of utilizing the MANTA VCD in patients undergoing this procedure., Methods: This single-center study included all patients undergoing percutaneous decannulation of femoral VA-ECMO using the MANTA plug-based VCD between January 2021 and October 2023 at University Hospitals Cleveland Medical Center. Inclusion criteria were adult patients who required prolonged (> 24 hours) hemodynamic support with VA-ECMO. Outcomes included all-cause mortality, hemostasis, bleeding, limb ischemia, and site infection., Results: This is a retrospective cohort study of 19 patients with a mean age of 56.8 years. Twelve of them were males with a mean body mass index of 29. The most common extracorporeal membrane oxygenation indication was acute coronary syndrome complicated by cardiogenic shock at 36.8%. The mean length of intensive care unit stay for these patients was 18.8 ± 8.42 days. Seventeen out of 19 patients survived to discharge. The MANTA device was successfully deployed in 19 patients, with 10 procedures conducted at the bedside and 9 in an operating room setting. Complete hemostasis was achieved within 5 minutes of MANTA deployment in 17 out of 19 patients. In 2 patients manual compression after Manta deployment was required to achieve adequate hemostasis. Additionally, acute lower extremity ischemia was noted in two patients, necessitating endovascular interventions. No infections were reported at the site of MANTA deployment., Conclusion: Overall, based on our experience and that of other centers, the MANTA VCD has proven to be a simple, safe, and effective percutaneous technique for facilitating in the OR, but most of all it opens the opportunity for bedside VA-ECMO decannulation. Post-decannulation ischemic complications are higher in this series of sick patients when compared with elective procedures like transcatheter aortic valve replacement and endovascular aneurysm repair. Additionally, operators should be mindful of the incidence of ischemic complications. Distal Doppler pulse signals should always be checked, to indicate bailout options when this occurs., Competing Interests: Conflict-of-interest statement: No conflict of interest is declared by the authors of this manuscript., (©The Author(s) 2024.

- Abstract
Objectives: The Veterans Health Administration (VA) is transitioning its 1,300 health care facilities from one electronic health record (EHR) to another. The transition aims to improve care delivery and interoperability; however, specific effects on women veterans, who comprise only 7.5% of the patient population, may be obscured without focused evaluation. We aimed to characterize the perspectives of VA staff regarding the impact of transitioning EHRs on women's health care delivery., Methods: We conducted semistructured interviews with VA staff members involved in delivering or coordinating care for women at three sites that had transitioned EHRs within the past year. Interviews were audio-recorded and transcribed. We used a rapid, templated qualitative analytic approach to identify salient themes in the data., Results: We interviewed 16 staff members across VA departments and roles. Although some participants felt the new EHR held promise, most identified challenges with the EHR rollout and implementation (e.g., insufficient training) and the EHR product (e.g., system inefficiencies and latency). Participants highlighted several ways the EHR transition disproportionately affected care delivery for women veterans, including via backlogs of community care referrals, insufficient opportunities for providers to gain proficiency with sex-specific workflows in the new EHR, and outdated listings for veterans who have changed their names. Participants reported that these issues affected their morale and contributed to decreases in productivity and delayed care., Conclusions: Many of our findings reflect challenges that affect VA staff broadly, whereas others may be compounded among women veterans and the VA staff who serve them. To achieve the goal of delivering timely, equitable, high-quality, comprehensive health care services to women veterans, continued efforts to monitor and address the impacts of the EHR transition on this population are needed., (Published by Elsevier Inc.)

- Abstract
Objective: Existing behavioral weight management interventions produce clinically meaningful weight loss. The onset of the COVID-19 pandemic led to the quick transition of such interventions from in-person to virtual platforms. This provided a unique opportunity to compare engagement and outcomes for an in-person versus virtually delivered weight management intervention., Methods: A non-randomized comparison of engagement and weight outcomes was performed between two cohorts who participated in a weight management intervention in person ( N = 97) versus three who participated virtually via videoconference ( N = 134). Various metrics of engagement were examined, including group class and individual phone call attendance and duration, and retention for weight assessments. Behavioral targets of daily caloric intake and step-counts and the clinical weight outcome were explored., Results: Cohorts (mean [standard deviation] age 47.3 (11.5), 67.1% women: 86.8% White) that participated virtually attended more group sessions ( p < 0.001) and had maintenance telephone calls that were of a longer duration ( p < 0.001). No other engagement or weight outcomes significantly differed by delivery modality., Conclusions: Virtual weight management programs are promising and may generate similar outcomes to those delivered in-person. Future research should seek to understand how best to promote and sustain engagement in virtual interventions., Competing Interests: Samantha Pabich is a Consultant for Eli Lilly and Company, and a Consultant for Dynamed.

- Abstract
Background: Partner support is associated with better weight loss outcomes in observational studies, but randomized trials show mixed results for including partners. Unclear is whether teaching communication skills to couples will improve weight loss in a person attempting weight loss (index participant)., Purpose: To compare the efficacy of a partner-assisted intervention versus participant-only weight management program on 24-month weight loss., Methods: This community-based study took place in Madison, WI. Index participants were eligible if they met obesity guideline criteria to receive weight loss counseling, were aged 18-74 years, lived with a partner, and had no medical contraindications to weight loss; partners were aged 18-74 years and not underweight. Couples were randomized 1:1 to a partner-assisted or participant-only intervention. Index participants in both arms received an evidence-based weight management program. In the partner-assisted arm, partners attended half of the intervention sessions, and couples were trained in communication skills. The primary outcome was index participant weight at 24 months, assessed by masked personnel; secondary outcomes were 24-month self-reported caloric intake and average daily steps assessed by an activity tracker. General linear mixed models were used to compare group differences in these outcomes following intent-to-treat principles., Results: Among couples assigned to partner-assisted (n = 115) or participant-only intervention (n = 116), most index participants identified as female (67%) and non-Hispanic White (87%). Average baseline age was 47.27 years (SD 11.51 years) and weight was 106.55 kg (SD 19.41 kg). The estimated mean 24-month weight loss was similar in the partner-assisted (2.66 kg) and participant-only arms (2.89 kg) (estimated mean difference, 0.23 kg [95% CI, -1.58, 2.04 kg], p=0.80). There were no differences in 24-month average daily caloric intake (estimated mean difference 50 cal [95% CI: -233, 132 cal], p=0.59) or steps (estimated mean difference 806 steps [95% CI: -1675, 64 steps], p=0.07). The percentage of participants reporting an adverse event with at least possible attribution to the intervention did not differ by arm (partner-assisted: 9%, participant-only, 3%, p = 0.11)., Conclusions: Partner-assisted and individual weight management interventions led to similar outcomes in index participants., Trial Registration: Clinicaltrials.gov NCT03801174, January 11, 2019., (© 2024.

- Abstract
Introduction: Veteran peer Coaches Optimizing and Advancing Cardiac Health was an randomized controlled trial (RCT) to test the effectiveness of a peer support intervention to reduce blood pressure among veterans with hypertension and 1 or more cardiovascular risks. The authors studied participant perceptions of the intervention, including barriers and facilitators to participation, factors promoting behavior change, and disease self-management practices., Methods: The authors enrolled participants at their exit visit for the Veteran peer Coaches Optimizing and Advancing Cardiac Health study. Participants received primary care at the Veterans Administration healthcare system and had multiple cardiovascular disease risks, including a diagnosis of hypertension. The authors conducted a qualitative content analysis of semistructured interviews about their experience with the Veteran peer Coaches Optimizing and Advancing Cardiac Health intervention., Results: Interview participants (N=29) were aged 60 years on average (SD=8.6), were 71% male, and were 55% White. They had mean systolic blood pressure of 138 mmHg (SD=18) at baseline. Authors identified themes across 3 major categories, which follow the general progression of the intervention: participation, relationship building, and behavior change. Scheduling flexibility, shared identity and experiences with the coach, acquisition of new knowledge and skills, and goal setting were important determinants of participants' experiences in the program. In the participation category, the themes were scheduling, visit modality, life circumstances, and staffing. In the relationship category, the themes were the coach's professional role, shared identity and experiences, and social support. In the behavior change category, the themes were memory, attention, and decision processes; goal setting; skills and knowledge; and environmental context and resources. Authors report differences across patients varying by blood pressure reduction after the intervention and number of coaching visits., Conclusions: Participants generally reported positive experiences in a peer support intervention for veterans with hypertension. Participant perceptions provide important insights into the intervention design and implementation. These findings may inform future implementation of peer support among veterans in hypertension and chronic disease self-management more generally., Trial Registration: This study was registered at Clinicaltrial.gov with the identifier NCT02697422., (© 2024 The Authors.)

- Abstract
Objective: Data suggest extracorporeal cardiopulmonary resuscitation (ECPR) improves survival in adult patients with refractory cardiac arrest; however, ECPR outcomes in pediatric patients with out-of-hospital cardiac arrest (OHCA) is lacking. The primary aim of this study was to characterize pediatric patients who experience OHCA or cardiac arrest in the ED (EDCA). The secondary aim was to examine associations of cardiac arrest and location of ECPR cannulation with mortality., Methods: We performed a retrospective analysis of the Extracorporeal Life Support Organization registry. We included pediatric patients (age > 28 days to <18 years) who received ECPR for refractory OHCA or EDCA between 2010 and 2019. Patient, cardiac arrest, and ECPR cannulation characteristics were summarized. We examined associations of location of cardiac arrest and ECPR cannulation with in-hospital mortality using multivariable logistic regression., Results: We analyzed data from 140 pediatric patients. 66 patients (47%) experienced OHCA and 74 patients (53%) experienced EDCA. Overall survival to hospital discharge was 31% (20% OHCA survival vs. 41% EDCA survival, p = 0.008). In adjusted analyses, OHCA was associated with 3.9 times greater odds of mortality (95% confidence interval [CI] 1.61, 9.81) when compared to compared to EDCA. The location of ECPR cannulation was not associated with mortality (odds ratio 1.8, 95% CI 0.75, 4.3)., Conclusions: The use of ECPR for pediatric patients with refractory OHCA is associated with poor survival compared to patients with EDCA. Location of ECPR cannulation does not appear to be associated with mortality., Competing Interests: Declaration of competing interest The authors have no disclosures of conflicts of interest to report., (Copyright © 2024 Elsevier Inc.

- Abstract
Objective: To identify constructs that are critical in shaping Veterans' experiences with Veterans Health Administration (VA) women's healthcare, including any which have been underexplored or are not included in current VA surveys of patient experience., Data Sources and Study Setting: From June 2022 to January 2023, we conducted 28 semi-structured interviews with a diverse, national sample of Veterans who use VA women's healthcare., Study Design: Using VA data, we divided Veteran VA-users identified as female into four groups stratified by age (dichotomized at age 45) and race/ethnicity (non-Hispanic White vs. all other). We enrolled Veterans continuously from each recruitment strata until thematic saturation was reached., Data Collection/extraction Methods: For this qualitative study, we asked Veterans about past VA healthcare experiences. Interview questions were guided by a priori domains identified from review of the literature, including trust, safety, respect, privacy, communication and discrimination. Analysis occurred concurrently with interviews, using inductive and deductive content analysis., Principal Findings: We identified five themes influencing Veterans' experiences of VA women's healthcare: feeling valued and supported, bodily autonomy, discrimination, past military experiences and trauma, and accessible care. Each emergent theme was associated with multiple of the a priori domains we asked about in the interview guide., Conclusions: Our findings underscore the need for a measure of patient experience tailored to VA women's healthcare. Existing patient experience measures used within VA fail to address several aspects of experience highlighted by our study, including bodily autonomy, the influence of past military experiences and trauma on healthcare, and discrimination. Understanding distinct factors that influence women and gender-diverse Veterans' experiences with VA care is critical to advance efforts by VA to measure and improve the quality and equity of care for all Veterans., (Published 2024.

- Abstract
Importance: The COVID-19 pandemic caused significant declines in the quality of preventive and chronic disease care. The Veterans Health Administration (VHA) used the Preventive Health Inventory (PHI), a multicomponent care management intervention, to catch up on care disrupted by the pandemic., Objective: To identify key factors associated with PHI use., Design, Setting, and Participants: This cohort study of veterans receiving primary care used administrative data from national VHA primary care clinics for February 1, 2021, through February 1, 2022., Exposure: Patient PHI receipt., Main Outcomes and Measures: The main outcomes were patient, practitioner, and clinic factors associated with PHI receipt. Binomial generalized linear models with fixed effects for clinic were used to analyze factors associated with receipt of PHI. Least absolute shrinkage and selection operator procedures were used for variable selection., Results: A total of 4 358 038 veterans (mean [SD] age, 63.7 [16.0] years; 90% male; 76% non-Hispanic White) formed the study cohort, of whom 389 757 (9%) received the PHI. Veterans who received the PHI had higher mean Care Assessment Need (CAN) scores, which indicate the likelihood of hospitalization or death within 1 year (mean [SD], 51.9 [28.6] vs 47.2 [28.6]; standardized mean difference [SMD], -0.16). They were also more likely to live in urban areas (77% vs 64%; SMD, 0.28) and have a shorter drive distance to primary care (mean [SD], 13.2 [12.4] vs 15.7 [14.6] miles; SMD, 0.19). The mean outpatient use was higher among PHI recipients compared with non-PHI recipients (mean [SD], 18.4 [27.8] vs 15.1 [24.1] visits; SMD, -0.13). In addition, veterans with primary care practitioners with higher caseloads were more likely to receive the PHI (mean [SD], 778 [231] vs 744 [249] patients; SMD, -0.14), and they were more likely to be seen at larger clinics (mean [SD], 9670 [6876] vs 8786 [6892] patients; SMD, -0.13). Prior outpatient use and CAN score were associated with PHI receipt in the final model., Conclusions and Relevance: In this cohort study of the VHA's PHI, patients with higher CAN scores and more outpatient use in the previous year were more likely to receive the PHI. This study identifies potential intervention points to improve care coordination for veterans.

- Abstract
Introduction: Uterine fibroids are common, nonmalignant tumors that disproportionately impact Black patients. We aimed to examine Black and White differences in receipt of any treatment and type of first treatment in the Department of Veterans Affairs, including effect modification by severity as approximated by anemia., Methods: We used Department of Veterans Affairs administrative data to identify 5,041 Black and 3,206 White veterans with symptomatic uterine fibroids, identified by International Classification of Diseases, 9th edition, Clinical Modification, codes, between fiscal year 2010 and fiscal year 2012 and followed in the administrative data through fiscal year 2018 for outcomes. Outcomes included receipt of any treatment, hysterectomy as first treatment, and fertility-sparing treatment as first treatment. We stratified all analyses by age (<45, ≥45 years old), used generalized linear models with a log link and Poisson error distribution, included an interaction term between race and anemia, and used recycled predictions to estimate adjusted percentages for outcomes., Results: There was evidence of effect modification by anemia for receipt of any treatment but not for any other outcomes. Across age and anemia sub-groups, Black veterans were less likely to receive any treatment than White veterans. Adjusted racial differences were most pronounced among veterans with anemia (<45 years, Black-White difference = -10.3 percentage points; 95% confidence interval, -15.9 to -4.7; ≥45 years, Black-White difference = -20.3 percentage points; 95% confidence interval, -27.8 to -12.7). Across age groups, Black veterans were less likely than White veterans to have hysterectomy and more likely to have a fertility-sparing treatment as their first treatment., Conclusions: We identified significant Black-White disparities in receipt of treatment for symptomatic uterine fibroids. Additional research that centers the experiences of Black veterans with uterine fibroids is needed to inform strategies to eliminate racial disparities in uterine fibroid care., (Published by Elsevier Inc.)

- Abstract
Introduction: The Department of Veterans Affairs (VA) relies on facilities outside of VA to provide mammograms for most VA patients. Prior work suggests challenges to coordinating some sex-specific services between VA and other health care systems (e.g., gynecologic malignancies, maternity care), but little is known about barriers and facilitators to mammogram care coordination. We sought to describe processes for coordinating mammograms referred outside of VA and to characterize VA staff perspectives on care coordination barriers and facilitators., Methods: We conducted semistructured interviews with 44 VA staff at 10 VA Medical Centers that refer all mammograms outside of the VA. Respondents included staff across multiple VA departments involved in coordinating mammograms. We used a rapid templated approach to analyze audio-recorded interviews to characterize the coordination processes and identify barriers and facilitators to care coordination., Results: Interviews elucidated a common mammogram care coordination process, with variability in how process steps were achieved. We identified six themes: 1) the process is generally perceived as inefficient, 2) clarity in VA staff roles and responsibilities is essential, 3) internal VA communication facilitates coordination, 4) challenges arise from variability in community provider processes and their limited understanding of VA processes, 5) coordination challenges can negatively impact veterans, and 6) technology holds promise but remains a barrier., Conclusions: Coordination of mammograms that are referred outside of VA is challenging for staff in multiple VA departments and roles. VA programs should focus on improving communication and role clarity within the VA and better harnessing technology to support coordination efforts., (Published by Elsevier Inc.)

- Abstract
Importance: Although cardiovascular disease (CVD) is the leading cause of death in the US, CVD risk factors remain suboptimally controlled., Objective: To test the effectiveness of a home-visit, peer health coaching intervention to improve health outcomes for veterans with multiple CVD risks., Design, Setting, and Participants: This 2-group, unblinded randomized clinical trial, called Vet-COACH (Veteran Peer Coaches Optimizing and Advancing Cardiac Health), used a novel geographic-based method to recruit a racially diverse population of veterans with low income. These veterans were enrolled at the Seattle or American Lake Veterans Health Affairs primary care clinics in Washington state. Veterans with a diagnosis of hypertension with at least 1 blood pressure reading of 150/90 mm Hg or higher in the past year, and 1 other CVD risk factor (current smoker, overweight or obesity, and/or hyperlipidemia), who resided in Census tracts with the highest prevalence of hypertension were eligible to participate. Participants were randomized to the intervention group (n = 134) or control group (n = 130). An intention-to-treat analysis was performed from May 2017 to October 2021., Intervention: Participants in the intervention group received peer health coaching for 12 months with mandatory and optional educational materials, an automatic blood pressure monitor, a scale, a pill organizer, and healthy nutrition tools. Participants in the control group received usual care plus educational materials., Main Outcomes and Measures: The primary outcome was a change in systolic blood pressure (SBP) from baseline to 12-month follow-up. Secondary outcomes included change in health-related quality of life (HRQOL; measured using the 12-item Short Form survey's Mental Component Summary and Physical Component Summary scores), Framingham Risk Score, and overall CVD risk and health care use (hospitalizations, emergency department visits, and outpatient visits)., Results: The 264 participants who were randomized (mean [SD] age of 60.6 [9.7] years) were predominantly male (229 [87%]) and 73 (28%) were Black individuals and 103 (44%) reported low annual income (<$40 000 per year). Seven peer health coaches were recruited. No difference was found in change in SBP between the intervention and control groups (-3.32 [95% CI, -6.88 to 0.23] mm Hg vs -0.40 [95% CI, -4.20 to 3.39] mm Hg; adjusted difference in differences, -2.05 [95% CI, -7.00 to 2.55] mm Hg; P = .40). Participants in the intervention vs control group reported greater improvements in mental HRQOL scores (2.19 [95% CI, 0.26-4.12] points vs -1.01 [95% CI, -2.91 to 0.88] points; adjusted difference in differences, 3.64 [95% CI, 0.66-6.63] points; P = .02). No difference was found in physical HRQOL scores, Framingham Risk Scores, and overall CVD risk or health care use., Conclusions and Relevance: This trial found that, although the peer health coaching program did not significantly decrease SBP, participants who received the intervention reported better mental HRQOL compared with the control group. The results suggest that a peer-support model that is integrated into primary care can create opportunities for well-being improvements beyond blood pressure control., Trial Registration: ClinicalTrials.gov Identifier: NCT02697422.

- Abstract
Background: Endoscopic esophageal stenting is used as an alternative to surgical repair for esophageal perforation. Multi-institutional studies supporting stenting are lacking. The purpose of this study was to compare the outcomes of surgical repair and esophageal stenting in patients with esophageal perforation using a nationally representative database. We hypothesized that mortality between these approaches would not be different., Methods: The Premier Healthcare Database was used to compare adult inpatients with esophageal perforation receiving either surgical repair or esophageal stenting from 2009 to 2019. Patients receiving intervention ≤7 days of admission were included in the analysis. Patients receiving both stent and repair on the same day were excluded. The composite outcome of interest was death or discharge to hospice. Logistic regression was used to evaluate independent predictors of death or hospice, adjusting for comorbidities., Results: There were 2543 patients with esophageal perforation identified who received repair (1314 [51.7%]) or stenting (1229 [48.3%]). Stenting increased from 7.0% in 2009 to 78.1% in 2019. Patients receiving repair were more likely to be female and White and had fewer Elixhauser comorbidities. Death or discharge to hospice was more common after stent (134/1314 [10.2%] repair vs 199/1229 [16.2%] stent; P < .001); however, after adjustment for comorbidities, logistic regression suggested that death or hospice discharge was similar between approaches (stent vs repair: odds ratio, 1.074; 95% CI, 0.81-1.42; P = .622). Hospital length of stay was shorter after stenting (stent vs repair coefficient, -4.09; P < .001)., Conclusions: In patients with esophageal perforation, the odds for death or discharge to hospice were similar for esophageal stenting compared with surgical repair., (Copyright © 2023 The Society of Thoracic Surgeons.

- Abstract
Importance: The COVID-19 pandemic caused significant disruptions in primary care delivery. The Veterans Health Administration (VHA) launched the Preventive Health Inventory (PHI) program-a multicomponent care management intervention, including a clinical dashboard and templated electronic health record note-to support primary care in delivering chronic disease care and preventive care that had been delayed by the pandemic., Objectives: To describe patient, clinician, and clinic correlates of PHI use in primary care clinics and to examine associations between PHI adoption and clinical quality measures., Design, Setting, and Participants: This quality improvement study used VHA administrative data from February 1, 2021, through February 28, 2022, from a national cohort of 216 VHA primary care clinics that have implemented the PHI. Participants comprised 829 527 veterans enrolled in primary care in clinics with the highest and lowest decile of PHI use as of February 2021., Exposure: Templated electronic health record note documenting use of the PHI., Main Outcomes and Measures: Diabetes and blood pressure clinical quality measures were the primary outcomes. Interrupted time series models were applied to estimate changes in diabetes and hypertension quality measures associated with PHI implementation. Low vs high PHI use was stratified at the facility level to measure whether systematic differences in uptake were associated with quality., Results: A total of 216 primary clinics caring for 829 527 unique veterans (mean [SD] age, 64.1 [16.9] years; 755 158 of 829 527 [91%] were men) formed the study cohort. Use of the PHI varied considerably across clinics. The clinics in the highest decile of PHI use completed a mean (SD) of 32 997.4 (14 019.3) notes in the electronic health record per 100 000 veterans compared with 56.5 (35.3) notes per 100 000 veterans at the clinics in the lowest decile of use (P < .001). Compared with the clinics with the lowest use of the PHI, clinics with the highest use had a larger mean (SD) clinic size (12 072 [7895] patients vs 5713 [5825] patients; P < .001), were more likely to be urban (91% vs 57%; P < .001), and served more non-Hispanic Black veterans (16% vs 5%; P < .001) and Hispanic veterans (14% vs 4%; P < .001). Staffing did not differ meaningfully between high- and low-use clinics (mean [SD] ratio of full-time equivalent staff to clinician, 3.4 [1.2] vs 3.4 [0.8], respectively; P < .001). After PHI implementation, compared with the clinics with the lowest use, those with the highest use had fewer veterans with a hemoglobin A1c greater than 9% or missing (mean [SD], 6577 [3216] per 100 000 veterans at low-use clinics; 9928 [4236] per 100 000 veterans at high-use clinics), more veterans with an annual hemoglobin A1c measurement (mean [SD], 13 181 [5625] per 100 000 veterans at high-use clinics; 8307 [3539] per 100 000 veterans at low-use clinics), and more veterans with adequate blood pressure control (mean [SD], 20 582 [12 201] per 100 000 veterans at high-use clinics; 12 276 [6850] per 100 000 veterans at low-use clinics)., Conclusions and Relevance: This quality improvement study of the implementation of the VHA PHI suggests that higher use of a multicomponent care management intervention was associated with improved quality-of-care metrics. The study also found significant variation in PHI uptake, with higher uptake associated with clinics with more racial and ethnic diversity and larger, urban clinic sites.

- Abstract
Objective: Describe the role of social support in veterans' diabetes self-management and examine gender differences., Methods: We conducted semi-structured interviews among veterans with diabetes from one Veterans Health Administration Health Care System. Participants described how support persons influenced their diabetes self-management and perspectives on a proposed self-management program incorporating a support person. We used thematic analysis to identify salient themes and examine gender differences., Results: Among 18 women and 18 men, we identified four themes: 1) women felt responsible for their health and the care of others; 2) men shared responsibility for managing their diabetes, with support persons often attempting to correct behaviors (social control); 3) whereas both men and women described receiving instrumental and informational social support, primarily women described emotional support; and 4) some women's self-management efforts were hindered by support persons. Regarding programs incorporating a support person, some participants endorsed including family/friends and some preferred programs including other individuals with diabetes., Conclusions: Notable gender differences in social support for self-management were observed, with women assuming responsibility for their diabetes and their family's needs and experiencing interpersonal barriers., Practice Implications: Gender differences in the role of support persons in diabetes self-management should inform support-based self-management programs., Competing Interests: Declaration of Competing Interest The authors have no competing interests to report., (Published by Elsevier B.V.)

- Abstract
Introduction: Uterine fibroids are the most common indication for hysterectomy. Minimally invasive hysterectomy (MIH) confers lower risk of complications and shorter recovery than open surgical procedures; however, it is more challenging to perform with larger fibroids. There are racialized differences in fibroid size and MIH rates. We examined the role of uterine size in black-white differences in MIH among Veterans in the Department of Veterans Affairs (VA)., Methods: Using VA clinical and administrative data, we conducted a cross-sectional study among black and white Veterans with fibroids who underwent hysterectomy between 2012 and 2014. We abstracted postoperative uterine weight from pathology reports as a proxy for uterine size. We used a generalized linear model to estimate the association between race and MIH and tested an interaction between race and postoperative uterine weight (≤250 g vs. >250 g). We estimated adjusted marginal effects for racial differences in MIH by postoperative uterine weight., Results: The sample included 732 Veterans (60% black, 40% white). Postoperative uterine weight modified the association of race and MIH ( p for interaction=0.05). Black Veterans with postoperative uterine weight ≤250 g had a nearly 12-percentage point decrease in MIH compared to white Veterans (95% CI -23.1 to -0.5), with no difference by race among those with postoperative uterine weight >250 g., Discussion: The racial disparity among Veterans with small fibroids who should be candidates for MIH underscores the role of other determinants beyond uterine size. To eliminate disparities in MIH, research focused on experiences of black Veterans, including pathways to treatment and provider-patient interactions, is needed., Competing Interests: No competing financial interests exist., (© Cathea M.

- Abstract
Background: The use of digital technologies and software allows for new opportunities to communicate and engage with research participants over time. When software is coupled with automation, we can engage with research participants in a reliable and affordable manner. Research Electronic Data Capture (REDCap), a browser-based software, has the capability to send automated text messages. This feature can be used to automate delivery of tailored intervention content to research participants in interventions, offering the potential to reduce costs and improve accessibility and scalability., Objective: This study aimed to describe the development and use of 2 REDCap databases to deliver automated intervention content and communication to index participants and their partners (dyads) in a 2-arm, 24-month weight management trial, Partner2Lose., Methods: Partner2Lose randomized individuals with overweight or obesity and cohabitating with a partner to a weight management intervention alone or with their partner. Two databases were developed to correspond to 2 study phases: one for weight loss initiation and one for weight loss maintenance and reminders. The weight loss initiation database was programmed to send participants (in both arms) and their partners (partner-assisted arm) tailored text messages during months 1-6 of the intervention to reinforce class content and support goal achievement. The weight maintenance and reminder database was programmed to send maintenance-related text messages to each participant (both arms) and their partners (partner-assisted arm) during months 7-18. It was also programmed to send text messages to all participants and partners over the course of the 24-month trial to remind them of group classes, dietary recall and physical activity tracking for assessments, and measurement visits. All text messages were delivered via Twilio and were unidirectional., Results: Five cohorts, comprising 231 couples, were consented and randomized in the Partner2Lose trial. The databases will send 53,518 automated, tailored text messages during the trial, significantly reducing the need for staff to send and manage intervention content over 24 months. The cost of text messaging will be approximately US $450. Thus far, there is a 0.004% known error rate in text message delivery., Conclusions: Our trial automated the delivery of tailored intervention content and communication using REDCap. The approach described provides a framework that can be used in future behavioral health interventions to create an accessible, reliable, and affordable method for intervention delivery and engagement that requires minimal trial-specific resources and personnel time., Trial Registration: ClinicalTrials.gov NCT03801174; https://clinicaltrials.gov/ct2/show/NCT03801174?term=NCT03801174., (©Hailey N Miller, Corrine I Voils, Kate A Cronin, Elizabeth Jeanes, Jeffrey Hawley, Laura S Porter, Rachel R Adler, Whitney Sharp, Samantha Pabich, Kara L Gavin, Megan A Lewis, Heather M Johnson, William S Yancy Jr, Kristen E Gray, Ryan J Shaw.

- Abstract
Background: Home telehealth (HT) programs enable communication and remote monitoring of patient health data between clinician visits, with the goal of improving chronic disease self-management and outcomes. The Veterans Health Administration (VHA) established one of the earliest HT programs in the country in 2003; however, little is known about how these services have been utilized and expanded over the last decade., Objective: To describe trends in use of VHA's HT program from 2010 through 2017 and correlates of length of enrollment in HT services., Design: Retrospective observational cohort study., Participants: Patients enrolled in HT between January 1, 2010 and December 31, 2017., Main Measures: We described the number and characteristics of patients enrolled in HT, including the chronic conditions managed. We also identified length of HT enrollment and examined patient and facility characteristics associated with longer enrollment., Key Results: The total number of patients enrolled in HT was 402,263. At time of enrollment, half were >65 years old, 91% were male, and 59.3% lived in urban residences. The most common conditions addressed by HT were hypertension (28.8%), obesity (23.9%), and diabetes (17.0%). The median time to disenrollment in HT was 261 days (8.6 months) but varied by chronic condition. In a multivariable Cox proportional hazards model, covariates associated with higher likelihood of staying enrolled were older age, male gender, non-Hispanic Black race/ethnicity, lower neighborhood socioeconomic status, living in a more rural setting, and a greater burden of comorbidities per the Gagne index., Conclusions: Across 8 years, over 400,000 veterans engaged in HT services for chronic disease management and over half remained in the program for longer than 8 months. Our work provides a real-world evaluation of HT service expansion in the VHA. Additional studies are necessary to identify optimal enrollment duration and patients most likely to benefit from HT services., (© 2022.

- Abstract
Background: The optimal minimally invasive surgical approach to mediastinal tumors is unknown. There are limited reports comparing the outcomes of resection with robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) surgery. We hypothesized that patients who underwent RATS would have improved outcomes., Methods: The National Cancer Database was queried for all patients who underwent a minimally invasive surgical approach for any mediastinal tumor from 2010 to 2016. Patients were determined to have an adverse composite outcome if they had any of the adverse perioperative outcomes: conversion to open procedure, 90-day mortality, 30-day readmission, and positive pathologic margins. Secondary outcomes of interest were length of stay and overall survival. Multivariable logistic regression was used to assess likelihood of having a composite adverse outcome based on surgical approach., Results: The study included 856 patients: 402 (47%) underwent VATS and 454 (53%) underwent RATS. RATS resections were associated with fewer conversions (4.9% vs 14.7%, P < .001), fewer positive margins (24.3% vs 31.6%, P = .02), shorter length of stay (3.8 days vs 4.3 days, P = .01), and fewer composite adverse events (36.7% vs 51.3%, P < .001). Multivariate analysis showed RATS (odds ratio, 0.44; P < .001) was independently associated with a decreased likelihood of a composite adverse outcome, even among tumors exceeding 4 cm (odds ratio, 0.45; P = .001). Overall survival was similar between the 2 groups., Conclusions: Among patients who underwent a minimally invasive surgical approach for a mediastinal tumor, RATS had fewer adverse outcomes than VATS, even for tumors 4 cm or larger. These data suggests that RATS may be the preferred technique for patients who are candidates for minimally invasive resection of mediastinal tumors., (Copyright © 2022 The Society of Thoracic Surgeons.

- Abstract
Introduction: In response to COVID-19, the Veterans Health Administration (VHA) converted appropriate outpatient visits to virtual care, including MOVE! Weight Management Program for Veterans (MOVE!) visits. Before the pandemic, most veterans participated in MOVE! in person, with several telehealth modalities available. We sought to describe national trends in MOVE! participation during the pandemic (March 2020-January 2021) overall and by modality and to compare participation to prepandemic levels., Methods: We conducted a national retrospective cohort study of veterans who participated in MOVE! from January 2018 through January 2021. We examined MOVE! participation across VHA aggregated at the national level by month, including the number of visits, participants, and new participants in person and via telehealth, including telephone, clinic-to-clinic synchronous video, anywhere-to-anywhere (eg, provider home to patient home) synchronous video, and remote education and monitoring. We also determined the percentage of all MOVE! visits attributable to each modality and the monthly percentage change in participation during the pandemic compared with monthly averages in prior years., Results: Before March 2020, 20% to 30% of MOVE! was delivered via telehealth, which increased to 90% by April 2020. Early in the pandemic, telephone-delivered MOVE! was the most common modality, but anywhere-to-anywhere synchronous video participation increased over time. Compared with the same months in prior years, total monthly MOVE! participation remained 20% to 40% lower at the end of 2020 and into January 2021., Conclusion: The VHA MOVE! program rapidly shifted to telehealth delivery of weight management services in response to the pandemic. However, a gap remained in the number of veterans receiving these services compared with prior years, suggesting potential unmet needs for weight management.

- Abstract
Current guidelines recommend anatomic lung resection of typical bronchopulmonary carcinoids. Typical carcinoid tumors have excellent prognosis and sublobar resection has been associated with noninferior long-term survival. It's unclear whether wedge resection is acceptable for small typical carcinoid tumors. We hypothesize there is no difference in survival between wedge resection and segmentectomy for Stage I typical bronchopulmonary carcinoid tumors. Using the National Cancer Database from 2010 to 2016, we identified clinical T1N0M0 typical bronchopulmonary carcinoid tumors by wedge resection or segmentectomy. Short-term outcomes included length of stay, lymph nodes evaluated, pathologic node status, positive margin status, and 90-day mortality. Primary outcome was overall survival and estimated using Kaplan-Meier survival analysis. 821 patients were identified: 677 receiving wedge resection, 144 receiving segmentectomy. Segmentectomy was more commonly performed in an academic setting (70.0% vs 57.3%, P = 0.005). The mean tumor size for segmentectomy was 1.7 cm versus 1.4 cm for wedge resection (P < 0.001). There was no difference in LOS, positive margin status, and 90-day mortality between groups. There were significantly more lymph nodes evaluated in segmentectomy patients (median 4 vs 0, P < 0.001), but there was no difference in positive lymph node status (5.3% vs 2.6%, P = 0.165). The OS was similar between wedge and segmental resection (P = 0.613): 3-year survival (93.5% vs 92.8%) and 5-year survival (83.8% vs 84.9%). Wedge resection and segmentectomy have similar survival for Stage I typical bronchopulmonary carcinoids in a large national database. This analysis suggests nonanatomic, parenchymal-sparing resection should be considered an appropriate alternative for Stage I typical bronchopulmonary carcinoids., (Copyright © 2021 Elsevier Inc.

- Abstract
People with low incomes have a disproportionate prevalence of diabetes and its complications and experience many barriers to self-management, which community health workers (CHWs) may help address. We sought to examine the effects of an in-home CHW-led intervention for adults with diabetes and incomes <250% of the federal poverty line on self-management behaviors and test mediators and moderators. From 2010 to 2013, we randomized participants from three Washington State health systems with type 2 diabetes and hemoglobin A1c (HbA1c) ≥ 8% to the CHW intervention (N = 145) or usual care control (N = 142) arms. We examined effects on 12-month self-management: physical activity, dietary behaviors, medication taking, blood glucose monitoring, foot care, and tobacco use. For behaviors with significant intervention-control group differences, we tested mediation by self-efficacy and social support. We also investigated whether intervention-associated changes in behaviors varied by race/ethnicity, gender, and baseline values of HbA1c, diabetes distress, depression, and food insecurity (moderators). Compared to controls, intervention participants engaged in more physical activity and reported better dietary behaviors for some measures (general diet, frequency of skipping meals, and frequency of eating out) at 12-months, but there was no evidence of mediation by self-efficacy or social support. Evidence of moderation was limited: improvements in the frequency of skipping meals were restricted to participants with baseline HbA1c < 10%. Study findings suggest CHWs could be integrated into diabetes care to effectively support lifestyle changes around physical activity and some eating behaviors among adults with low incomes. More research is needed to understand mechanisms of change., (Published by Oxford University Press on behalf of the Society of Behavioral Medicine 2021.)

- Abstract
Objectives: Women experiencing early pregnancy loss (EPL) frequently present to the emergency department (ED), but little is known about who receives EPL care in these settings. We aimed to estimate the proportion of ED visits for EPL-related care and determine characteristics associated with seeking care for EPL in the ED in a national sample., Methods: We conducted a secondary analysis of the 2006-2016 National Hospital Ambulatory Medical Care Survey (NHAMCS), a nationally representative survey of US ED visits. We identified women ages 15-44 years who presented to the ED for threatened or confirmed EPL based on diagnosis code or chief complaint. We estimated the proportion of ED visits attributable to EPL-related care among all ED visits and among women 15-44 years old. Using multivariable logistic regression, we evaluated patient and visit characteristics associated with receiving EPL-related care versus all other care., Results: The 2006-2016 NHAMCS dataset included 325,037 visits (weighted n = 1,447,144,423), including 82,871 visits among women ages 15-44 years (weighted n = 371,016,125). Of all ED visits for women ages 15-44 years, 2.7% (95% confidence interval, 2.5-2.9) were for EPL-related care. This equates to ≈900,000 visits annually. Compared with women ages 15-44 years presenting to the ED for other reasons, those presenting for EPL-related care were younger and more likely to be Black or Hispanic., Conclusions: EPL-related care accounts for over 900,000 ED visits in the United States each year. These findings highlight the current burden of EPL visits upon EDs nationally., Competing Interests: The authors declare no conflict of interest., (© 2021 The Authors.

- Abstract
Introduction: Robotic minimally invasive esophagectomy (RMIE) and "traditional" minimally invasive esophagectomy techniques (tMIE) have reported superior outcomes relative to open techniques. Differences in the outcomes of these two approaches have not been examined. We hypothesized that short-term outcomes of RMIE would be superior to tMIE., Methods and Procedures: The National Cancer Database was used to analyze outcomes of patients undergoing RMIE and tMIE from 2010 to 2016. Patients with clinical metastatic disease were excluded. Trends in the number of procedures performed with each approach were described using linear regression testing. Primary outcome of interest was 90-day mortality rate. Secondary outcomes of interest were positive surgical margin rate, number of lymph nodes (LN) removed, adequate lymphadenectomy (> 15 LNs), length of hospitalization (LOS), readmission rate, and conversion to open rate. Outcomes of RMIE and tMIE were compared using Wilcoxon rank sum test and chi square test as appropriate. Multivariable regression was also performed to reduce the impact of differences in the cohorts of patients receiving RMIE and tMIE., Results: 6661 minimally invasive esophagectomies were performed from 2010 to 2016 (1543/6661 (23.2%) RMIE and 5118/6661 (76.8%) tMIE). Over the study period, the proportion of RMIE increased from 10.4% (64/618) in 2010 to 27.2% (331/1216) in 2016 (p < 0.001) (Fig. 1). The primary outcome of 90-day mortality was similar between RMIE and tMIE (92/1170 (7.4%) vs 305/4148 (7.9%), p = 0.558) (Table 2). RMIE and tMIE also had similar readmission rate (6.3 vs 7%, p = 0.380). There was no difference between the cohorts based on sex, age, race, insurance, and tumor size. The cohorts of patients receiving RMIE and tMIE differed in that RMIE patients had lower rates of elevated Charlson scores, were more likely to be treated at an academic institution, had a higher rate of advanced clinical T-stage and clinical nodal involvement, and had received neoadjuvant therapy. In a univariate analysis, RMIE had a lower rate of positive margin (3.9 vs 6.1%, p = 0.001), more mean lymph nodes evaluated (16.6 ± 9.74 vs 16.1 ± 10.08 p = 0.018), lower conversion to open rate (5.4 vs 11.4%, p < 0.001), and a shorter mean length of stay (12.1 ± 10.39 vs 12.8 ± 11.18 days, p < 0.001). In multivariable analysis, RMIE was associated with lower risk of conversion to open (OR 0.51, 95% CI: 0.37-0.70, p < 0.001) and lower rate of positive margin (OR 0.62, 95% CI: 0.41-0.93, p = 0.021).). Additionally, in a multivariable logistic regression, RMIE demonstrated superior adequate lymphadenectomy (> 15 LNs) (OR 1.18, 95% CI 1.02-1.37, p < 0.032)., Conclusion: In the National Cancer Database, robotic esophagectomy is associated with superior rate of conversion to open and positive surgical margin status. We speculate enhanced dexterity and visualization of RMIE facilitates intraoperative performance leading to improvement in these outcomes., (© 2020.

- Abstract
Background: Robotic minimally invasive esophagectomies (RMIE) have been associated with superior outcomes; however, it is unclear if these are specific to robotic technique or are present only at high-volume institutions. We hypothesize that low-volume RMIE centers would have inferior outcomes., Methods: The National Cancer Database (NCDB) identified patients receiving RMIE from 2010 to 2016. Based on the total number of RMIE performed by each hospital system, the lowest quartile performed ≤ 9 RMIE over the study period. Ninety-day mortality, number of lymph nodes evaluated, margins status, unplanned readmissions, length of stay (LOS), and overall survival were compared. Regression models were used to account for confounding., Results: 1565 robotic esophagectomies were performed by 212 institutions. 173 hospitals performed ≤ 9 RMIE (totaling 478 operations over the study period, 30.5% of RMIE) and 39 hospitals performed > 9 RMIE (1087 operations, 69.5%). Hospitals performing > 9 RMIE were more likely to be academic centers (90.4% vs 66.2%, p < 0.001), have patients with advanced tumor stage (65.3% vs 59.8%, p = 0.049), andadministered preoperative radiation (72.8% vs 66.3%, p = 0.010). There were no differences based on demographics, nodal stage, or usage of preoperative chemotherapy. On multivariable regressions, hospitals performing ≤ 9 RMIE were associated with a greater likelihood of experiencing a 90-day mortality, a reduced number of lymph nodes evaluated, and a longer LOS; however, there was no association with rates of positive margins or unplanned readmissions. Median overall survival was decreased at institutions performing ≤ 9 RMIE (37.3 vs 51.5 months, p < 0.001). Multivariable Cox regression demonstrated an association with poor survival comparing hospitals performing ≤ 9 to > 9 RMIE (HR 1.327, p = 0.018)., Conclusion: Many robotic esophagectomies occur at institutions which performed relatively few RMIE and were associated with inferior short- and long-term outcomes. These data argue for regionalization of robotic esophagectomies or enhanced training in lower volume hospitals.

- Abstract
Background: Robotic esophagectomies are increasingly common and are reported to have superior outcomes compared with an open approach; however, it is unclear if all institutions can achieve such outcomes. We hypothesize that early adopters of robotic technique would have improved short-term outcomes., Methods: The National Cancer Database (2010-2016) was used to identify robotic esophagectomies. Early adopters were defined as programs which performed robotic esophagectomies in 2010-2011, late adopters in 2012-2013. Outcomes of esophagectomies performed between 2014 and 2016 were compared and included length of stay, number of lymph nodes evaluated, readmission, conversion rate, and 90-day mortality. Multivariable regressions, accounting for robotic esophagectomy volume, were used to control for confounding factors., Results: There were 37 early adopters and 35 late adopters. Between 2014 and 2016, 683 robotic esophagectomies were performed: 446 (65.3%) by early adopters and 237 (34.7%) by late adopters. Early adopters were more likely to be academic programs (96.2 versus 72.8%, P < 0.01). Other clinical and demographic variables were similar. Late adopters were found to have decreased a number of lymph nodes evaluated (coefficient -2.407, P = 0.004) compared with early adopters. There were no significant differences in length of stay, readmissions, rate of positive margins, conversion from robotic to open, or 90-day mortality., Conclusions: When accounting for robotic esophagectomy volume, late adoption of robotic esophagectomy was associated with a reduced lymph node harvest, but other postoperative outcomes were similar. These data suggest that programs can safely start new robotic esophagectomy programs, but must ensure an adequate case load., (Copyright © 2020 Elsevier Inc. All rights reserved.)

- Abstract
Purpose: Social support is an important correlate of health behaviors and outcomes. Studies suggest that veterans have lower social support than civilians, but interpretation is hindered by methodological limitations. Furthermore, little is known about how sex influences veteran-civilian differences. Therefore, we examined veteran-civilian differences in several dimensions of social support and whether differences varied by sex., Methods: We performed a cross-sectional analysis of the 2012-2013 National Epidemiologic Survey of Alcohol and Related Conditions-III, a nationally representative sample of 34,331 respondents (male veterans = 2569; female veterans = 356). We examined veteran-civilian differences in functional and structural social support using linear regression and variation by sex with interactions. We adjusted for socio-demographics, childhood experiences, and physical and mental health., Results: Compared to civilians, veterans had lower social network diversity scores (difference [diff] = - 0.13, 95% confidence interval [CI] - 0.23, - 0.03). Among women but not men, veterans had smaller social network size (diff = - 2.27, 95% CI - 3.81, - 0.73) than civilians, attributable to differences in religious groups, volunteers, and coworkers. Among men, veterans had lower social network diversity scores than civilians (diff = - 0.13, 95% CI - 0.23, - 0.03); while among women, the difference was similar but did not reach statistical significance (diff = - 0.13, 95% CI - 0.23, 0.09). There was limited evidence of functional social support differences., Conclusion: After accounting for factors that influence military entry and social support, veterans reported significantly lower structural social support, which may be attributable to reintegration challenges and geographic mobility. Findings suggest that veterans could benefit from programs to enhance structural social support and improve health outcomes, with female veterans potentially in greatest need.

- Abstract
Background: Hysterectomy can be performed with concomitant bilateral salpingo-oophorectomy (BSO) to treat symptomatic pathology of the ovary ( e.g. , endometriosis) or to prevent ovarian cancer. Our objective was to examine the relationship between race and concomitant BSO by menopausal status in the Veterans Affairs (VA) health care system. Methods: This is a longitudinal study utilizing VA administrative data to identify hysterectomies provided or paid for by VA ( i.e. , source of care) between 2007 and 2014. We defined BSO as removal of both ovaries and fallopian tubes at the time of hysterectomy, identified by International Classification of Diseases-Ninth Revision codes. Covariates included demographic ( e.g. , ethnicity) and gynecological diagnoses ( e.g. , endometriosis). We used generalized linear models with a log-link and binomial distribution to estimate associations of race with BSO by menopausal status and source of care. Results: We identified 6,785 Veterans with hysterectomies, including 2,320 with concomitant BSO. Overall, Black Veterans were more likely to be single, obese, and undergo abdominal hysterectomy. After adjustment, premenopausal Black Veterans had a 41% lower odds of BSO than their White counterparts (odds ratio [OR]: 0.59, 95% confidence interval [CI]: 0.51-0.68). Stratifying on source of care, these results remained unchanged (provided: OR: 0.61, 95% CI: 0.52-0.72; paid: OR: 0.58, 95% CI: 0.48-0.71). There was insufficient evidence of an association among postmenopausal Veterans. Conclusions: Premenopausal Black Veterans are less likely to undergo BSO even after adjustment for salient characteristics. Our findings may have implications for equitable gynecological care for Veterans. Additional research is needed to better understand the role of differential preferences or cancer risk in these racial differences.

- Abstract
Background: Thoracoscopic pneumonectomy commonly requires conversion to thoracotomy. We hypothesize that conversion would lead to worse short- and long-term outcomes compared with operations completed thoracoscopically., Methods: The National Cancer Database identified patients who underwent a pneumonectomy from 2010 to 2016. Trends in conversion were described using linear regression. Multivariable regression of factors associated with conversion was performed. Short-term outcomes included duration of stay, number of lymph nodes harvested, margin status, readmission, and 90-day mortality. Long-term outcome was evaluated as overall survival., Results: A total of 8,037 patients underwent a pneumonectomy. The rate of attempted thoracoscopic pneumonectomies increased from 11% to 22% (P < .001) and the rate of conversion decreased from 39% to 33% (P = .011). On multivariable analysis, a greater patient comorbidity index and pathologic nodal-stage 2 disease were associated with an increased rate of conversion. The mean number of lymph nodes evaluated was greater as was the duration of stay in the conversion group, but conversion to open thoracotomy was not associated with positive surgical margins, readmission rate, 90-day mortality, or survival., Conclusion: Thoracoscopic pneumonectomy is performed with increasing frequency and decreasing conversion rate. Conversion is associated with a greater duration of stay but other short- and long-term outcomes are similar. This observation suggests minimal harm in conversion from minimally invasive to open pneumonectomy., (Copyright © 2020 Elsevier Inc. All rights reserved.)

- Abstract
Background: When hysterectomy is used to treat uterine fibroids, a minimally invasive versus open abdominal approach is preferred. Depression and post-traumatic stress disorder (PTSD) may be associated with surgical mode. We sought to examine whether depression and PTSD are associated with minimally invasive hysterectomy (MIH)., Methods: This was a cross-sectional study of veterans with uterine fibroids undergoing hysterectomy in the Department of Veterans Affairs between 2012 and 2014. Diagnoses and procedures were identified by International Classification of Disease, Ninth Revision, codes. MIH was defined as laparoscopic, vaginal, or robotic-assisted versus open abdominal. A dichotomous variable indicated presence of depression or PTSD. Clinical variables, including uterine size, were abstracted from the medical record. We employed generalized linear models to estimate adjusted percentages and 95% confidence intervals (CIs) of MIH by presence of depression or PTSD and sequentially adjusted for sociodemographic variables and health indicators (model 1), and then gynecologic and reproductive history variables, including uterine size (model 2)., Results: We included 770 veterans in our analytic sample. Veterans with depression or PTSD were more likely than those without such diagnoses to have a MIH (49% vs. 42%). Differences were attenuated in model 1 (47% [95% CI, 37%-57%] vs. 43% [95% CI, 34%-52%]) and no longer detectable in model 2 (45% [95% CI, 36%-54%] vs. 44% [95% CI, 36%-52%])., Conclusions: Veterans with depression or PTSD were more likely that those without to have a MIH, possibly owing to smaller uterine size, suggesting that they may be undergoing hysterectomy earlier in the disease process. Further research is needed to understand whether this reflects high-quality, patient-centered care., (Published by Elsevier Inc.)

- Abstract
Background: Approximately one-half of women undergoing hysterectomy in the Department of Veterans Affairs health care system receive minimally invasive hysterectomies (MIH), with Black women less likely than White women to receive MIH. We sought to characterize gynecologists' perspectives on factors contributing to the availability and provision of MIH and on the role of race/ethnicity in decision making., Methods: Between October 2017 and January 2018, we conducted 16 in-depth semistructured telephone interviews with Department of Veterans Affairs gynecologists exploring practice characteristics and barriers and facilitators to providing MIH, including clinical and nonclinical characteristics of patients impacting surgical decision making. We identified key themes using simultaneous deductive and inductive thematic analysis., Results: Gynecologists identified provider-, facility-, and patient-level barriers and facilitators to MIH. Provider-level factors included gynecologists' skills and training in MIH, and facility factors included access to qualified surgical assistants, availability of surgical equipment, and operating room resources, particularly time. On the patient level, clinical characteristics, including uterine size, were the most common determinants of surgical approach, but nonclinical factors such as patients' attitudes toward surgery also contributed. Race/ethnicity was identified by a minority of respondents as influencing hysterectomy route through clinical presentation and surgical attitudes., Conclusions: Given the range of factors identified, efforts to promote MIH in the Department of Veterans Affairs will likely require a multipronged approach that includes support for MIH training, increased access to surgical assistants with MIH skills, and reduced barriers to obtaining equipment. Patient perspectives are needed to more fully capture nonclinical patient-level contributors to MIH and differences in MIH between Black and White Veterans., (Published by Elsevier Inc.)

- Abstract
Background: Although most surgery residents pursue fellowships, data regarding those decisions are limited. This study describes associations with interest in fellowship and specific subspecialties., Methods: Anonymous surveys were distributed to 607 surgery residents at 19 US programs. Subspecialties were stratified by levels of burnout and quality of life using data from recent studies., Results: 407 (67%) residents responded. 372 (91.4%) planned to pursue fellowship. Fellowship interest was lower among residents who attended independent or small programs, were married, or had children. Residents who received AOA honors or were married were less likely to choose high burnout subspecialties (trauma/vascular). Residents with children were less likely to choose low quality of life subspecialties (trauma/transplant/cardiothoracic)., Conclusions: Surgery residents' interest in fellowship and specific subspecialties are associated with program type and size, AOA status, marital status, and having children. Variability in burnout and quality of life between subspecialties may affect residents' decisions., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Background: Minimally invasive hysterectomy for fibroids decreases recovery time and risk of postoperative complications compared with abdominal hysterectomy. Within Veterans Affair (VA), black women with uterine fibroids are less likely to receive a minimally invasive hysterectomy than white women., Objective: To quantify the contributions of patient, facility, temporal and geographic factors to VA black-white disparity in minimally invasive hysterectomy., Research Design: A cross-sectional study., Subjects: Veterans with fibroids and hysterectomy performed in VA between October 1, 2012 and September 30, 2015., Measures: Hysterectomy mode was defined using ICD-9 codes as minimally invasive (laparoscopic, vaginal, or robotic-assisted) versus abdominal. The authors estimated a logistic regression model with minimally invasive hysterectomy modeled as a function of 4 sets of factors: sociodemographic characteristics other than race, health risk factors, facility, and temporal and geographic factors. Using decomposition techniques, systematically substituting each white woman's characteristics for each black woman's characteristics, then recalculating the predicted probability of minimally invasive hysterectomy for black women for each possible combination of factors, we quantified the contribution of each set of factors to observed disparities in minimally invasive hysterectomy., Results: Among 1255 veterans with fibroids who had a hysterectomy at a VA, 61% of black women and 39% of white women had an abdominal hysterectomy. Our models indicated there were 99 excess abdominal hysterectomies among black women. The majority (n=77) of excess abdominal hysterectomies were unexplained by measured sociodemographic factors beyond race, health risk factors, facility, and temporal or geographic trends., Conclusion: Closer examination of the equity of VA gynecology care and ways in which the VA can work to ensure equitable care for all women veterans is necessary.

- Abstract
Background: In the general population, Black and Latina women are less likely to undergo minimally invasive hysterectomy than White women, which may be related to racial/ethnic variation in fibroid prevalence and characteristics. Whether similar differences exist in the Department of Veterans Affairs Healthcare System (VA) is unknown., Methods: Using VA clinical and administrative data, we identified all women veterans undergoing hysterectomy for benign indications in fiscal years 2012-2014. We identified hysterectomy route (laparoscopic with/without robot-assist, vaginal, abdominal) by International Classification of Diseases, 9th edition, codes. We used multinomial logistic regression to estimate associations of race/ethnicity with hysterectomy route and tested whether associations varied by fibroid diagnosis using an interaction term. Models adjusted for age, income, body mass index, gynecologic diagnoses, medical comorbidities, whether procedure was performed or paid for by VA, geographic region, and fiscal year., Results: Among 2,744 identified hysterectomies, 53% were abdominal, 29% laparoscopic, and 18% vaginal. In multinomial models, racial/ethnic differences were present among veterans with but not without fibroid diagnoses (p value for interaction < .001). Among veterans with fibroids, Black veterans were less likely than White veterans to have minimally invasive hysterectomy (laparoscopic vs. abdominal relative risk ratio [RRR], 0.52; 95% CI, 0.38-0.72; vaginal vs. abdominal RRR, 0.58; 95% CI, 0.43-0.73). Latina veterans were as likely as White veterans to have laparoscopic as abdominal hysterectomy (RRR, 1.34; 95% CI, 0.87-2.07) and less likely to have vaginal than abdominal hysterectomy (RRR, 0.32; 95% CI, 0.15-0.69)., Conclusions: Receipt of minimally invasive hysterectomy among women veterans with fibroids varied by race/ethnicity. Further investigation of the underlying mechanisms and potential interventions to increase minimally invasive hysterectomy among minority women veterans is needed., (Published by Elsevier Inc.)

- Abstract
Background: A key mechanism thought to underlie Posttraumatic Stress Disorder (PTSD) is enhanced emotional memory consolidation. Recent evidence in healthy controls revealed that women have greater negative memory consolidation following stress relative to men. This study examined emotional memory consolidation in women and men with PTSD, and in trauma-exposed and non-trauma controls to test the hypothesis that emotionally negative memory consolidation would be greater in women with PTSD., Method: One hundred and forty-seven men and women (47 with PTSD, 49 trauma-exposed controls, and 51 non-trauma controls) completed an emotional memory task where they looked at negative, neutral and positive images from the International Affective Picture System (IAPS). Delayed recall and an intrusive memory diary were completed two days later., Results: Women displayed greater recall, and reported more negative intrusive memories than men. A gender x group interaction effect showed that both women with PTSD and trauma-exposed women reported more intrusive memories than women without trauma exposure or men., Conclusion: This study provided preliminary evidence of sex differences in intrusive memories in those with PTSD as well as those with a history of trauma exposure. Future research should include measures of sex hormones to further examine sex differences on memory consolidation in the context of trauma exposure and PTSD., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
The literature on the reproductive health and healthcare of women Veterans has increased dramatically, though there are important gaps. This article aims to synthesize recent literature on reproductive health and healthcare of women Veterans. We updated a literature search to identify manuscripts published between 2008 and July 1, 2017. We excluded studies that were not original research, only included active-duty women, or had few women Veterans in their sample. Manuscripts were reviewed using a standardized abstraction form. We identified 52 manuscripts. Nearly half (48%) of the new manuscripts addressed contraception and preconception care ( n = 15) or pregnancy ( n = 10). The pregnancy and family planning literature showed that (1) contraceptive use and unintended pregnancy among women Veterans using VA healthcare is similar to that of the general population; (2) demand for VA maternity care is increasing; and (3) women Veterans using VA maternity care are a high-risk population for adverse pregnancy outcomes. A recurrent finding across topics was that history of lifetime sexual assault and mental health conditions were highly prevalent among women Veterans and associated with a wide variety of adverse reproductive health outcomes across the life course. The literature on women Veterans' reproductive health is rapidly expanding, but remains largely observational. Knowledge gaps persist in the areas of sexually transmitted infections, infertility, and menopause., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)
