- Abstract
Objectives: Most older adults with lesbian, gay, bisexual, queer, questioning, transgender, and related identities (LGBTQ+) are concerned about receiving lower-quality care and/or being mistreated in nursing homes. Older LGBTQ+ veterans may have additional reservations about care in Department of Veterans Affairs (VA) nursing homes (Community Living Centers [CLCs]) because of experience with past discriminatory military policies (eg, bans on participating in military service, Don't Ask Don't Tell). This article describes one of the first VA CLCs to participate in the Human Rights Campaign-developed Long-Term Care Equality Index (LEI)., Design: A single-site formative evaluation was completed to support quality improvement and identify opportunities for growth using the LEI. The LEI is a facility benchmarking tool to support more inclusive environments for LGBTQ+ residents and employees. The LEI offers 4 evaluation criteria: (1) Non-Discrimination and Staff Training; (2) LGBTQ+ Resident Services and Support; (3) Employee Benefits and Policies; and (4) Resident and Community Engagement. Facilities receive ratings based on the number of requirements achieved in each category., Participants and Methods: Older LGBTQ+ veterans, current CLC residents, interdisciplinary CLC providers and leadership, and national Geriatrics and Extended Care program managers collaborated to pilot the LEI and develop tools and materials to support other VA facilities' participation in the LEI., Results: Qualitative interviews with veterans and CLC residents supported inclusion of gender identity and sexual orientation in resident handbooks, discussions about person-centered care, and opportunities for additional staff training and community engagement (eg, observing Pride Month in June). Resources to support VA long-term care facilities' participation in the LEI were developed., Conclusions and Implications: The LEI offers a structured approach to identifying areas for improvement in providing high-quality and equitable care in long-term care settings. Practical suggestions for CLCs and other nursing home settings considering the LEI for the first time are discussed., Competing Interests: Disclosure The authors declare no conflicts of interest., (Published by Elsevier Inc.)

- Abstract
Introduction: It remains uncertain whether Descemet membrane endothelial keratoplasty (DMEK) or Descemet stripping only (DSO) yields better outcomes in patients with symptomatic Fuchs endothelial corneal dystrophy (FECD). This paper presents the protocol for the Descemet Endothelial Thickness Comparison Trial II (DETECT II), a multicentre, outcome-masked, randomised, placebo-controlled, clinical trial comparing DMEK to DSO with ripasudil (DSO-R) for this patient population., Methods and Analysis: A total of 60 patients with endothelial dysfunction due to symptomatic FECD will be enrolled from seven participating sites in the USA. The patients will be randomly assigned in a 1:1 ratio to one of the following treatment groups: group 1-DMEK plus topical placebo and group 2-DSO plus topical ripasudil 0.4%. The enrolment period is 24 months. The primary outcome is best spectacle-corrected visual acuity at 12 months. Secondary outcomes include peripheral and central endothelial cell density, visual acuity, vision-related quality of life and Pentacam Scheimpflug tomography. Study outcomes will be analysed using mixed effects linear regression. Adverse events, including rebubble procedures, endothelial failure and graft rejection, will be documented and analysed using appropriate statistical methods. DETECT II aims to provide evidence on the comparative effectiveness of DMEK and DSO-R. The results of this trial will contribute to optimising the treatment of FECD, while also exploring the cost-effectiveness of these interventions. Dissemination of findings through peer-reviewed publications and national/international meetings will facilitate knowledge translation and guide clinical practice in the field of corneal transplantation., Ethics and Dissemination: A data and safety monitoring committee has been empanelled by the National Eye Institute. All study protocols will be subject to review and approval by WCG IRB as the single IRB of record. This study will comply with the National Institute of Health (NIH) Data Sharing Policy and Policy on the Dissemination of NIH-Funded Clinical Trial Information and the Clinical Trials Registration and Results Information Submission rule.

- Abstract
Purpose: The Steroids and Cross-linking for Ulcer Treatment Trial is an NIH-funded international, randomized, double-masked, sham and placebo-controlled clinical trial to determine the benefit of adjunctive corneal cross-linking with riboflavin and/or topical difluprednate in addition to topical antibiotic drops for treatment of smear-positive bacterial ulcers. The purpose of this study was to explore the baseline characteristics for infection of patients enrolled, and the ocular comorbidities of patients screened for inclusion., Methods: Of the 2005 patients with smear-positive bacterial ulcers screened, 280 patients were enrolled. Descriptive statistics were used to summarize and characterize the data., Results: Eligible patients in India had baseline factors associated with agricultural work (N = 132; 47%) and manual labor (N = 54; 19%), whereas patients in the United States were associated with contact lens wear (N = 11; 69%) (P <0.001). Nearly, 10% of patients with unilateral infectious keratitis are at risk of bilateral blindness because of preexisting visual disability in their other eye and thus ineligible for inclusion. India had higher rates of exclusionary factors for blindness in the other eye such as cataract (N = 48; 27%) and glaucoma (N = 24; 13) compared with the United States (N = 0; 0%) (P <0.001)., Conclusions: While corneal ulceration is an important cause of disability in technologically advanced countries, it occurs more frequently in low and middle-income countries, and the implications on these populations should be considered. These baseline factors can be evaluated to address such health care disparities., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Background: Infectious keratitis secondary to fungus or acanthamoeba often has a poor outcome despite receiving the best available medical therapy. In vitro Rose Bengal Photodynamic therapy (RB-PDT) appears to be effective against fungal and acanthamoeba isolates.
22,23 In one published series RB-PDT reduced the need for therapeutic penetrating keratoplasty in severe bacterial, fungal, and acanthameoba keratitis not responsive to medical therapy., Methods: This international, randomized, sham and placebo controlled 2-arm clinical trial, randomizes patients with smear positive fungal and acanthameoba and smear negative corneal ulcers in a 1:1 fashion to one of two treatment arms: 1) Topical antimicrobial plus sham RB-PDT or 2) Topical antimicrobial plus RB-PDT., Discussion: We anticipate that RB-PDT will improve best spectacle corrected visual acuity and also reduce complications such as corneal perforation and the need for therapeutic penetrating keratoplasty. This study will comply with the NIH Data Sharing Policy and Policy on the Dissemination of NIH-Funded Clinical Trial Information and the Clinical Trials Registration and Results Information Submission rule. Our results will be disseminated via clinicaltrials.gov website, meetings, and journal publications. Our data will also be available upon reasonable request., Trial Registration: NCT, NCT05110001, Registered November 5, 2021. https://www.clinicaltrials.gov/study/NCT05110001., Competing Interests: Competing Interests There are no conflicts of interest to report.- Published

- Abstract
Background: It remains uncertain which endothelial keratoplasty (EK) technique yields the best outcomes while maintaining safety, particularly in eyes with coexisting ocular conditions. Moreover, the impact of endothelial cell loss (ECL) on long-term graft survival requires further investigation. Adjuvant ripasudil, a rho kinase inhibitor, may address the challenge of ECL in corneal transplantation. This paper presents the protocol for the Descemet Endothelial Thickness Comparison Trial 1 (DETECT 1), a multicentre, outcome-masked, randomised, placebo-controlled, four-arm clinical trial., Methods: A total of 160 eligible patients with endothelial dysfunction will be enrolled from five participating sites in the USA. The patients will be randomly assigned in a 2×2 factorial design to one of the following treatment groups: group 1-ultrathin Descemet stripping endothelial keratoplasty (UT-DSAEK) plus topical ripasudil 0.4%; group 2-UT-DSAEK plus topical placebo; group 3-Descemet membrane endothelial keratoplasty (DMEK) plus topical ripasudil 0.4% and group 4-DMEK plus topical placebo. Primary outcomes include the best spectacle-corrected visual acuity at 12 months and ECL at 12 months. Secondary outcomes include visual acuity at different time points, vision-related quality of life, endothelial cell morphology and cost-effectiveness., Results: The study outcomes will be analysed using mixed effects linear regression models, taking into account the treatment arms and relevant covariates. Adverse events, including rebubble procedures, graft failure and graft rejection, will be documented and analysed using appropriate statistical methods., Conclusion: DETECT I aims to provide evidence on the comparative effectiveness of UT-DSAEK and DMEK, as well as the potential benefits of adjuvant topical ripasudil in reducing ECL. The results of this trial will contribute to optimising corneal transplantation techniques and improving long-term graft survival, while also exploring the cost-effectiveness of these interventions.

- Abstract
Objective: To examine the acceptability of routine screening for adverse childhood experiences (ACEs) and resilience during prenatal care., Method: This study examined pregnant women's perspectives ( N = 119) on ACEs and resilience screening during prenatal care in two medical centers via postscreening telephone surveys. Chi-square tests and Fisher's Exact Tests examined whether responses varied with ACEs (0 [62.2%], 1-2 [21.0%], 3+ [16.8%]) or resilience (high [64.7%] vs. low [35.3%])., Results: The sample ( N = 119) was 36.1% non-Hispanic White, 26.1% Hispanic, 8.4% Black, 23.5% Asian/Pacific Islander, and 5.9% Other, with a median age of 31 (IQR: 28-34) and average neighborhood median household income of $100,734 (SD = $37,079). Most women thought prenatal care should include conversations about ACEs (82.2%) and resilience (94.0%) and very strongly believed that good coping skills can help reduce the harmful effects of childhood stress (79.0%). Nearly half (41.2%) used ≥1 mental health resource from the resource handout provided at screening. Some women thought conversations could be improved if they took place with a mental health professional (37.3%), with more provider empathy (40.7%), more education about ACEs and health (55.1%), and if the screening included additional stressors (53.4%). Notably, most women (73.5%) would like their partner to also receive the screening. Women with more ACEs were more likely to want a longer conversation, and those with low versus high resilience were more likely to prefer that a mental health professional conduct the screening., Conclusions: Results indicate that women value ACEs screening during prenatal care and provide actionable recommendations to improve future screenings and discussions.

- Abstract
Introduction: Biomarkers of Human Papillomavirus (HPV) cervical carcinogenesis are critical to address questions of how to triage and manage women who screen positive for high-risk HPV (HrHPV) and identify those at highest cancer risk., Methods: We describe the development of a large biorepository of cervical specimens for the Improving Risk Informed HPV Screening Study (IRIS) using residual specimens collected in the regional laboratory from women aged 25 and older who had cervical cancer screening or follow-up testing with high-risk human papillomavirus (HrHPV) testing and liquid-based cytology (co-testing) at Kaiser Permanente Northern California (KPNC) from January 2016 to August 2018. Specimen selection, processing for long-term storage, follow-up tracking, consent and demographic and clinical characteristics of the women in the IRIS cohort are described., Results: Selecting from 897,680 women who had at least one co-test during the study period, we collected 199,403 baseline and 216,390 follow-up HrHPV and cytology specimens from a stratified random sample of 81,348 women, of which 3,428 (4.2%) opted out of the study and were excluded. The majority (79.9%) of the baseline specimens were from HrHPV-positive women. The mean age was 36 years, and the cohort is racially/ethnically diverse with 56% of women being Hispanic or non-white. Over two-thirds of the cohort were members of KPNC for two or more years prior to inclusion. Of the 77,920 women included in the cohort, 57,414 (73.7%) had at least one follow-up co-test., Conclusion: Use of specimens from the biorepository will elucidate molecular mechanisms underlying HPV carcinogenesis and inform more effective screening and follow-up strategies., (Copyright © 2021.

- Abstract
Background: This study examined whether adverse childhood experiences (ACEs) are associated with increased risk of having an unwanted or mistimed pregnancy., Methods: Women in two medical centers within an integrated health system were screened for ACEs during standard prenatal care (N = 745). Multinomial multivariable logistic regression analyses examined the associations of ACEs (count and type) with pregnancy intentions, adjusting for covariates., Results: Overall, 58.3% of pregnant women reported no ACEs, 19.1% reported one ACE, and 22.7% reported two or more ACEs; 76.2% reported wanting to get pregnant, 18.5% reported wanting to get pregnant but not at this time (i.e., mistimed pregnancy), and 5.2% reported not wanting to get pregnant at all (i.e., unwanted pregnancy). Having two or more (vs. 0) ACEs was associated with higher odds of an unwanted pregnancy (odds ratio, 2.60; 95% confidence interval, 1.19-5.68). Further, childhood loss of parent (odds ratio, 2.20; 95% confidence interval, 1.03-4.71) and neglect (odds ratio, 5.67; 95% confidence interval, 1.72-18.72) were each associated with higher odds of an unwanted pregnancy in separate analyses. ACEs count and type were not significantly associated with having a mistimed pregnancy., Conclusions: Among women screened for ACEs during standard prenatal care, ACEs were associated with increased odds of having an unwanted pregnancy, but not a mistimed pregnancy. Additional research is needed to better understand the mechanisms through which ACEs and other individual, social, and contextual factors impact pregnancy intentions to better support women and provide appropriate resources to help prevent unintended pregnancies., (Copyright © 2020 Jacobs Institute of Women's Health.

- Abstract
Purpose: To examine whether adverse childhood experiences (ACEs) are associated with breastfeeding behaviors. Methods: Women in three Kaiser Permanente Northern California medical centers were screened for ACEs during standard prenatal care ( N = 926). Multivariable binary and multinomial logistic regression was used to test whether ACEs (count and type) were associated with early breastfeeding at the 2-week newborn pediatric visit and continued breastfeeding at the 2-month pediatric visit, adjusting for covariates. Results: Overall, 58.2% of women reported 0 ACEs, 19.2% reported 1 ACE, and 22.6% reported 2+ ACEs. Two weeks postpartum, 92.2% reported any breastfeeding (62.9% exclusive, 29.4% mixed breastfeeding/formula). Compared with women with 0 ACEs, those with 2+ ACEs had increased odds of any breastfeeding (odds ratio [OR] = 2.7, 95% confidence interval [CI] = 1.3-5.6) and exclusive breastfeeding 2 weeks postpartum (OR = 3.0, 95% CI = 1.4-6.3). Among those who breastfed 2 weeks postpartum, 86.4% reported continued breastfeeding (57.5% exclusive, 28.9% mixed breastfeeding/formula) 2 months postpartum. ACE count was not associated with continued breastfeeding 2 months postpartum. Individual ACEs were not related to breastfeeding outcomes, with the exception that living with someone who went to jail or prison was associated with lower odds of continued breastfeeding 2 months postpartum. Conclusions: ACE count was associated with greater early breastfeeding, but not continued breastfeeding, among women screened for ACEs as part of standard prenatal care. Results reiterate the need to educate and assist all women to meet their breastfeeding goals, regardless of ACE score.

- Abstract
Motivation: Recent advancements in high-throughput imaging have created new large datasets with tens of thousands of gene expression images. Methods for capturing these spatial and/or temporal expression patterns include in situ hybridization or fluorescent reporter constructs or tags, and results are still frequently assessed by subjective qualitative comparisons. In order to deal with available large datasets, fully automated analysis methods must be developed to properly normalize and model spatial expression patterns., Results: We have developed image segmentation and registration methods to identify and extract spatial gene expression patterns from RNA in situ hybridization experiments of Drosophila embryos. These methods allow us to normalize and extract expression information for 78,621 images from 3724 genes across six time stages. The similarity between gene expression patterns is computed using four scoring metrics: mean squared error, Haar wavelet distance, mutual information and spatial mutual information (SMI). We additionally propose a strategy to calculate the significance of the similarity between two expression images, by generating surrogate datasets with similar spatial expression patterns using a Monte Carlo swap sampler. On data from an early development time stage, we show that SMI provides the most biologically relevant metric of comparison, and that our significance testing generalizes metrics to achieve similar performance. We exemplify the application of spatial metrics on the well-known Drosophila segmentation network., Availability: A Java webstart application to register and compare patterns, as well as all source code, are available from: http://tools.genome.duke.edu/generegulation/image_analysis/insitu, Contact: uwe.ohler@duke.edu, Supplementary Information: Supplementary data are available at Bioinformatics online.
