Complement factor B is critical for sub-RPE deposit accumulation in a model of Doyne honeycomb retinal dystrophy with features of age-related macular degeneration.

EFEMP1 R345W is a dominant mutation causing Doyne honeycomb retinal dystrophy/malattia leventinese (DHRD/ML), a rare blinding disease with clinical pathology similar to age-related macular degeneration (AMD). Aged Efemp1  R345W/R345W knock-in mice (Efemp1ki/ki) develop microscopic deposits on the basal side of retinal pigment epithelial cells (RPE), an early feature in DHRD/ML and AMD. Here, we assessed the role of alternative complement pathway component factor B (FB) in the formation of these deposits. RNA-seq analysis of the posterior eyecups revealed increased unfolded protein response, decreased mitochondrial function in the neural retina (by 3 months of age) and increased inflammatory pathways in both neural retina and posterior eyecups (at 17 months of age) of Efemp1ki/ki mice compared with wild-type littermate controls. Proteomics analysis of eye lysates confirmed similar dysregulated pathways as detected by RNA-seq. Complement activation was increased in aged Efemp1ki/ki eyes with an approximately 2-fold elevation of complement breakdown products iC3b and Ba (P < 0.05). Deletion of the Cfb gene in female Efemp1ki/ki mice partially normalized the above dysregulated biological pathway changes and oral dosing of a small molecule FB inhibitor from 10 to 12 months of age reduced sub-RPE deposits by 65% (P = 0.029). In contrast, male Efemp1ki/ki mice had fewer sub-RPE deposits than age-matched females, no elevation of ocular complement activation and no effect of FB inhibition on sub-RPE deposits. The effects of FB deletion or inhibition on Efemp1ki/ki mice supports systemic inhibition of the alternative complement pathway as a potential treatment of dry AMD and DHRD/ML.

Leveraging Electronic Health Records to Assess Residential Mobility Among Veterans in the Veterans Health Administration.

BACKGROUND: Residential mobility, or a change in residence, can influence health care utilization and outcomes. Health systems can leverage their patients' residential addresses stored in their electronic health records (EHRs) to better understand the relationships among patients' residences, mobility, and health. The Veteran Health Administration (VHA), with a unique nationwide network of health care systems and integrated EHR, holds greater potential for examining these relationships. METHODS: We conducted a cross-sectional analysis to examine the association of sociodemographics, clinical conditions, and residential mobility. We defined residential mobility by the number of VHA EHR residential addresses identified for each patient in a 1-year period (1/1-12/31/2018), with 2 different addresses indicating one move. We used generalized logistic regression to model the relationship between a priori selected correlates and residential mobility as a multinomial outcome (0, 1, ≥2 moves). RESULTS: In our sample, 84.4% (n=3,803,475) veterans had no move, 13.0% (n=587,765) had 1 move, and 2.6% (n=117,680) had ≥2 moves. In the multivariable analyses, women had greater odds of moving [aOR=1.11 (95% CI: 1.10,1.12) 1 move; 1.27 (1.25,1.30) ≥2 moves] than men. Veterans with substance use disorders also had greater odds of moving [aOR=1.26 (1.24,1.28) 1 move; 1.77 (1.72,1.81) ≥2 moves]. DISCUSSION: Our study suggests about 16% of veterans seen at VHA had at least 1 residential move in 2018. VHA data can be a resource to examine relationships between place, residential mobility, and health.

Cutting-edge care: unleashing artificial intelligence's potential in gynecologic surgery.

PURPOSE OF REVIEW: Artificial intelligence (AI) is now integrated in our daily life. It has also been incorporated in medicine with algorithms to diagnose, recommend treatment options, and estimate prognosis. RECENT FINDINGS: AI in surgery differs from virtual AI used for clinical application. Physical AI in the form of computer vision and augmented reality is used to improve surgeon's skills, performance, and patient outcomes. SUMMARY: Several applications of AI and augmented reality are utilized in gynecologic surgery. AI's potential use can be found in all phases of surgery: preoperatively, intra-operatively, and postoperatively. Its current benefits are for improving accuracy, surgeon's precision, and reducing complications.

Human NOP2/NSUN1 regulates ribosome biogenesis through non-catalytic complex formation with box C/D snoRNPs.

5-Methylcytosine (m5C) is a base modification broadly found on various RNAs in the human transcriptome. In eukaryotes, m5C is catalyzed by enzymes of the NSUN family composed of seven human members (NSUN1-7). NOP2/NSUN1 has been primarily characterized in budding yeast as an essential ribosome biogenesis factor required for the deposition of m5C on the 25S ribosomal RNA (rRNA). Although human NOP2/NSUN1 has been known to be an oncogene overexpressed in several types of cancer, its functions and substrates remain poorly characterized. Here, we used a miCLIP-seq approach to identify human NOP2/NSUN1 RNA substrates. Our analysis revealed that NOP2/NSUN1 catalyzes the deposition of m5C at position 4447 on the 28S rRNA. We also find that NOP2/NSUN1 binds to the 5'ETS region of the pre-rRNA transcript and regulates pre-rRNA processing through non-catalytic complex formation with box C/D snoRNAs. We provide evidence that NOP2/NSUN1 facilitates the recruitment of U3 and U8 snoRNAs to pre-90S ribosomal particles and their stable assembly into snoRNP complexes. Remarkably, expression of both WT and catalytically inactive NOP2/NSUN1 in knockdown background rescues the rRNA processing defects and the stable assembly of box C/D snoRNP complexes, suggesting that NOP2/NSUN1-mediated deposition of m5C on rRNA is not required for ribosome synthesis.

Feasibility and Perioperative Outcomes of Minimally Invasive Higher Order Myomectomy.

STUDY OBJECTIVE: To investigate perioperative outcomes of minimally invasive higher order myomectomy as defined by removal of 10 or more fibroids. DESIGN: A retrospective cohort study between January 2018 and December 2022. SETTING: A tertiary academic medical center. PATIENTS: Women who underwent minimally invasive myomectomy via laparoscopic or robotic approach. INTERVENTIONS: Surgical intervention in the form of minimally invasive myomectomy. MEASUREMENTS AND MAIN RESULTS: A total of 735 women met inclusion criteria of whom 578 had fewer than 10 fibroids removed, and 157 patients had 10 or more removed (average number of fibroids removed 3.8 vs 14.7, p <.001; specimen's weight 317.4 g vs 371.0 g, p = .07). Body mass index was similar in both groups (p = .66) and patients with higher order myomectomy were more likely to have a history of myomectomy (12.0% vs 26.8%, p <.001). The average estimated blood loss (EBL) was 246 mL vs 470 mL in each group (p <.001). There were no significant differences in packed red blood cell transfusion (1.0% vs 0.6%, p = .65), conversion to laparotomy (0.5% vs 0.6%, p = .86), or complications including visceral injury, wound complication, venous thromboembolism, ileus, or readmission (5.9% vs 4.5%, p = .49). The hospital length of stay was similar in both groups (0.5 days vs 0.5 days, p = .63). On linear regression analysis, after adjusting for specimen's weight, operative time, and history of myomectomy, EBL remained significantly higher in patients with 10 or more fibroids removed (p = .02). CONCLUSION: EBL is increased in higher order myomectomy; however, blood transfusions, conversion to laparotomy, complication rates, and length of hospital stay did not differ compared with patients with fewer than 10 fibroids removed, highlighting the feasibility of minimally invasive higher order myomectomy.

Enhanced Identification of Hispanic Ethnicity Using Clinical Data: A Study in the Largest Integrated United States Health Care System.

BACKGROUND: Collection of accurate Hispanic ethnicity data is critical to evaluate disparities in health and health care. However, this information is often inconsistently recorded in electronic health record (EHR) data. OBJECTIVE: To enhance capture of Hispanic ethnicity in the Veterans Affairs EHR and compare relative disparities in health and health care. METHODS: We first developed an algorithm based on surname and country of birth. We then determined sensitivity and specificity using self-reported ethnicity from the 2012 Veterans Aging Cohort Study survey as the reference standard and compared this to the research triangle institute race variable from the Medicare administrative data. Finally, we compared demographic characteristics and age-adjusted and sex-adjusted prevalence of conditions in Hispanic patients among different identification methods in the Veterans Affairs EHR 2018-2019. RESULTS: Our algorithm yielded higher sensitivity than either EHR-recorded ethnicity or the research triangle institute race variable. In 2018-2019, Hispanic patients identified by the algorithm were more likely to be older, had a race other than White, and foreign born. The prevalence of conditions was similar between EHR and algorithm ethnicity. Hispanic patients had higher prevalence of diabetes, gastric cancer, chronic liver disease, hepatocellular carcinoma, and human immunodeficiency virus than non-Hispanic White patients. Our approach evidenced significant differences in burden of disease among Hispanic subgroups by nativity status and country of birth. CONCLUSIONS: We developed and validated an algorithm to supplement Hispanic ethnicity information using clinical data in the largest integrated US health care system. Our approach enabled clearer understanding of demographic characteristics and burden of disease in the Hispanic Veteran population.

National Institutes of Health Diversity Supplement Awards by Medical School.

BACKGROUND: Increasing medical school faculty diversity is an urgent priority. National Institutes of Health (NIH) diversity supplements, which provide funding and career development opportunities to individuals underrepresented in research, are an important mechanism to increase faculty diversity. OBJECTIVE: Analyze diversity supplement utilization by medical schools. DESIGN: Retrospective cohort study. PARTICIPANTS: All R01 grant-associated diversity supplements awarded to medical schools from 2005 to 2020. Diversity supplements were identified using the publicly available NIH RePORTER database. MAIN MEASURES: Main measures were the number of R01-associated diversity supplements awarded to medical schools each year by medical school NIH funding status and the number of R01-associated diversity supplements awarded to individual medical schools in the NIH top 40 by funding status. We also examined the percentage of R01 grants with an associated diversity supplement by NIH funding status and individual medical school in the NIH top 40. KEY RESULTS: From 2005 to 2020, US medical school faculty received 1389 R01-associated diversity supplements. The number of diversity supplements awarded grew from 2012 to 2020, from ten to 187 for top 40 schools, and from seven to 83 for non-top 40 schools. The annual growth rate for diversity supplement awards at NIH top 40 schools (44.2%) was not significantly different than the annual growth rate among non-top 40 schools (36.2%; p = 0.68). From 2005 to 2020, the highest number of diversity supplements that an individual medical school received was 56 and the lowest number was four (mean = 24.6, SD = 11.7). The highest percentage of R01 grants with an associated diversity supplement received by a school was 4.5% and the lowest percentage was 0.79% (mean = 2.3%, SD = 0.98). CONCLUSION: Medical schools may be missing an opportunity to address the continuing shortage of individuals historically underrepresented in biomedical science and should consider additional mechanisms to enhance diversity supplement utilization.

Laparoscopic administration of bupivacaine at the uterosacral ligaments during benign laparoscopic and robotic hysterectomy: a randomized controlled trial.

BACKGROUND: Postoperative pain continues to be an undermanaged part of the surgical experience. Multimodal analgesia has been adopted in response to the opioid epidemic, but opioid prescribing practices remain high after minimally invasive hysterectomy. Novel adjuvant opioid-sparing analgesia to optimize acute postoperative pain control is crucial in preventing chronic pain and minimizing opioid usage. OBJECTIVE: This study aimed to determine the effect of direct laparoscopic uterosacral bupivacaine administration on opioid usage and postoperative pain in patients undergoing benign minimally invasive (laparoscopic and robotic) hysterectomy. STUDY DESIGN: This was a single-blinded, triple-arm, randomized controlled trial at an academic medical center between March 15, 2021, and April 8, 2022. The inclusion criteria were patients aged >18 years undergoing benign laparoscopic or robotic hysterectomy. The exclusion criteria were non-English-speaking patients, patients with an allergy to bupivacaine or actively using opioid medications, patients undergoing transversus abdominis plane block, and patients undergoing supracervical hysterectomy or combination cases with other surgical services. Patients were randomized in a 1:1:1 fashion to the following uterosacral administration before colpotomy: no administration, 20 mL of normal saline, or 20 mL of 0.25% bupivacaine. All patients received incisional infiltration with 10 mL of 0.25% bupivacaine. The primary outcome was 24-hour oral morphine equivalent usage (postoperative day 0 and postoperative day 1). The secondary outcomes were total oral morphine equivalent usage in 7 days, last day of oral morphine equivalent usage, numeric pain scores from the universal pain assessment tool, and return of bowel function. Patients reported postoperative pain scores, total opioid consumption, and return of bowel function via Qualtrics surveys. Patient and surgical characteristics and primary and secondary outcomes were compared using chi-square analysis and 1-way analysis of variance. Multiple linear regression was used to identify predictors of opioid use in the first 24 hours after surgery and total opioid use in the 7 days after surgery. RESULTS: Of 518 hysterectomies screened, 410 (79%) were eligible, 215 (52%) agreed to participate, and 180 were ultimately included in the final analysis after accounting for dropout. Most hysterectomies (70%) were performed laparoscopically, and the remainder were performed robotically. Most hysterectomies (94%) were outpatient. Patients randomized to bupivacaine had higher rates of former and current tobacco use, and patients randomized to the no-administration group had higher rates of previous surgery. There was no difference in first 24-hour oral morphine equivalent use among the groups (P=.10). Moreover, there was no difference in numeric pain scores (although a trend toward significance in discharge pain scores in the bupivacaine group), total 7-day oral morphine equivalent use, day of last opioid use, or return of bowel function among the groups (P>.05 for all). The predictors of increased 24-hour opioid usage among all patients included only increased postanesthesia care unit oral morphine equivalent usage. The predictors of 7-day opioid usage among all patients included concurrent tobacco use and mood disorder, history of previous laparoscopy, estimated blood loss of >200 mL, and increased oral morphine equivalent usage in the postanesthesia care unit. CONCLUSION: Laparoscopic uterosacral administration of bupivacaine at the time of minimally invasive hysterectomy did not result in decreased opioid usage or change in numeric pain scores.

Educating Mental Health Trainees About Measurement-Based Care: A Scoping Review.

OBJECTIVE: Measurement-based care (MBC) refers to the routine use of symptom rating scales to guide treatment decisions. Although effective, it is an underused approach to enhance patient care. A significant barrier to integration of MBC is insubstantial foundational training. This scoping review aims to survey the literature on MBC educational curricula for mental health trainees. METHODS: Investigators searched Ovid Medline, PsycINFO, Embase, Cochrane Central, and Ebsco CINAHL through June 2021 to select records that described studies of MBC educational programs for undergraduate, graduate, or postgraduate learners in mental healthcare. RESULTS: From 1270 unique records, 1263 were excluded in abstract/title and full-text screening. This scoping review included seven articles, of which most were empirical or case studies and took place in the USA. These curricula involved many delivery formats, including lectures and in-service training. Measured learner outcomes include those that are learner-focused (i.e. learner reaction, or attitudinal/behavioral change) and organizational-focused (i.e. increased clinical use of MBC). Mechanisms of positive outcomes are posited to include enhanced stakeholder support and continual curriculum improvement. CONCLUSIONS: MBC curricula can be taught in various formats to diverse learners in mental healthcare. Contextual factors, such as dedicated resources, MBC champions, supervisor training, online measurement feedback systems, simple measures, and gathering and disseminating feedback may facilitate curricular success by fostering stakeholder support and continual program improvement. To address literature gaps, future research in MBC education should involve educational frameworks in designing curriculum and address the use of quality improvement approaches in the implementation of MBC education.

A highly multiplexed quantitative phosphosite assay for biology and preclinical studies.

Reliable methods to quantify dynamic signaling changes across diverse pathways are needed to better understand the effects of disease and drug treatment in cells and tissues but are presently lacking. Here, we present SigPath, a targeted mass spectrometry (MS) assay that measures 284 phosphosites in 200 phosphoproteins of biological interest. SigPath probes a broad swath of signaling biology with high throughput and quantitative precision. We applied the assay to investigate changes in phospho-signaling in drug-treated cancer cell lines, breast cancer preclinical models, and human medulloblastoma tumors. In addition to validating previous findings, SigPath detected and quantified a large number of differentially regulated phosphosites newly associated with disease models and human tumors at baseline or with drug perturbation. Our results highlight the potential of SigPath to monitor phosphoproteomic signaling events and to nominate mechanistic hypotheses regarding oncogenesis, response, and resistance to therapy.

Impact of Obesity on Clinical and Financial Outcomes of Minimally Invasive Hysterectomy for Benign Conditions.

OBJECTIVE: To evaluate the effect of obesity on clinical and financial outcomes of minimally invasive hysterectomy METHODS: This was a retrospective cohort study of 5 affiliated hospitals. We obtained demographic, operative, and financial characteristics to analyze the effects of obesity on outcomes, including operating room (OR) time, estimated blood loss (EBL), length of stay (LOS), adverse perioperative events, and hospital charges. Obesity was stratified by the following classes: no obesity (BMI <30 kg/m2), class I (BMI 30-34 kg/m2), class II (BMI 35-39 kg/m2), and class III (BMI >40 kg/m2). Descriptive statistics and multivariate logistic and linear regressions were performed. RESULTS: A total of 2483 women underwent benign, minimally invasive hysterectomy. Laparoscopic was the most common approach (79.8%), followed by robotic (12.2%), and vaginal (8.0%). Mean BMI was 30.13 ± 6.99 kg/m2, and total charges were US $13 928 ± $5954. Each additional minute in the OR increased costs by US $47.89 (P < 0.001). Compared with patients without obesity, OR time and EBL were significantly higher among patients with class I or II obesity and highest among patients with class III obesity (P < 0.001). Obesity did not affect LOS or occurrence of adverse perioperative events. Although obesity appeared to be a significant predictor of hysterectomy charges, after adjusting for covariates, charges for laparoscopic and robotic hysterectomy did not differ significantly by BMI. CONCLUSION: Obesity appears to have a significant effect on clinical outcomes of benign hysterectomy that is approach-dependent and most notable among patients with class III obesity. BMI was not, however, a predictor of financial outcomes.

Environmentally relevant mixtures of phthalates and phthalate metabolites differentially alter the cell cycle and apoptosis in mouse neonatal ovaries†.

Phthalates are a group of chemicals used as additives in various consumer products, medical equipment, and personal care products. Phthalates and their metabolites are consistently detected in humans, indicating widespread and continuous exposure to multiple phthalates. Thus, environmentally relevant mixtures of phthalates and phthalate metabolites were investigated to determine the effects of phthalates on the function of the ovary during the neonatal period of development. Neonatal ovaries from CD-1 mice were cultured with dimethyl sulphoxide (DMSO; vehicle control), phthalate mixture (0.1-100 µg/mL), or phthalate metabolite mixture (0.1-100 µg/mL). The phthalate mixture was composed of 35% diethyl phthalate, 21% di(2-ethylhexyl) phthalate, 15% dibutyl phthalate, 15% diisononyl phthalate, 8% diisobutyl phthalate, and 5% benzylbutyl phthalate. The phthalate metabolite mixture was composed of 37% monoethyl phthalate, 19% mono(2-ethylhexyl) phthalate, 15% monobutyl phthalate, 10% monoisononyl phthalate, 10% monoisobutyl phthalate, and 8% monobenzyl phthalate. After 96 h of culture, ovaries were harvested for histological analysis of folliculogenesis, gene expression analysis of cell cycle and apoptosis regulators, and immune staining for cell proliferation and apoptosis. The metabolite mixture significantly decreased the number and percentage of abnormal follicles (100 µg/mL) compared to controls. The metabolite mixture also significantly increased the expression of cell cycle inhibitors (100 µg/mL) and the antiapoptotic factor Bcl2l10 (10 µg/mL) compared to controls. The phthalate mixture did not significantly alter gene expression or follicle counts, but ovaries exposed to the phthalate mixture (0.1 µg/mL) exhibited marginally significantly increased apoptosis as revealed by DNA fragmentation staining. Overall, these data show that parent phthalates and phthalate metabolites differentially impact ovarian function.

Evaluating the effectiveness of the Family Connections program for caregivers of youth with mental health challenges, part II: A qualitative analysis.

BACKGROUND: The Family Connections™ (FC) program is a 12-week support and skill-training program for caregivers of youth with mental health challenges. The intervention was originally developed with a focus on borderline personality disorder (BPD). It is important to understand the experiences of caregivers in such interventions, as well as its applicability beyond BPD, for the purposes of evaluation and ongoing program improvement. OBJECTIVE: To explore and analyse the experiences of caregivers of youth with diverse mental health challenges and who participated in FC. DESIGN: Semi-structured interviews with thirteen FC-participating caregivers of youth with mental health challenges. RESULTS: Thematic analysis uncovered three major themes regarding caregivers' experience with FC: (a) FC increased the caregivers' ability to manage their youth's mental health challenges; (b) participating in FC impacted their intra- and interpersonal spheres; and (c) improvements to the program were proposed. Following participation in FC, caregivers felt they learned a new approach to understanding themselves, their youth and mental health, and were better able to manage their youth's mental health challenges. DISCUSSION AND CONCLUSION: FC is a promising intervention for caregivers of youth with mental health challenges, beyond the traditional BPD focus. The intervention has the potential to provide broad-based benefits for caregivers and should be considered for implementation and scale-up across youth- and caregiver-serving organizations. Potential areas of intervention flexibility and improvement are discussed. PATIENT/PUBLIC CONTRIBUTION: Caregivers were involved in the program development and facilitation of FC. A person with lived experience was involved with the analysis.

Demonstration of Safe Entry Techniques for Laparoscopy.

STUDY OBJECTIVE: To demonstrate different techniques, and detail the considerations for obtaining primary laparoscopic access in gynecologic surgery. DESIGN: Video demonstration of the techniques with narrated discussion of each method. SETTING: The methods for primary entry in laparoscopy vary by location and technique [1,2]. There are inherent risks with any mode of primary entry, and the risks are also specific to each technique [3-6]. The choice for primary entry depends on the patient's anatomy, surgical history, pathology, and surgeon preference [1,2]. INTERVENTIONS: This video reviews considerations for choosing the safest entry point and tips for proper entry technique [4,7-10]. The entry sites reviewed include the umbilicus, left upper quadrant, right upper quadrant, and supraumbilical [11]. The entry technique can be either open (Hasson), closed (Veress), or by direct laparoscopic visualization [9,10,12-14]. CONCLUSION: No single laparoscopic entry technique is superior [3]. The safest and most successful entry method will vary by case characteristics and surgeon training.

Egocentric Health Networks and Cardiovascular Risk Factors in the ECHORN Cohort Study.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the Caribbean region. OBJECTIVE: This study explored the concept of a health network, relationships focused on health-related matters, and examined associations with CVD risk factors in the Eastern Caribbean. DESIGN: The Eastern Caribbean Health Outcomes Research Network Cohort Study is an ongoing longitudinal cohort being conducted in the US Virgin Islands, Puerto Rico, Trinidad and Tobago, and Barbados. PARTICIPANTS: Participants (n = 1989) were English or Spanish-speaking adults 40 years and older, who were residents of the island for at least 10 years, and who intended to live on-island for the next 5 years. MAIN MEASURES: Logistic regression was used to examine associations between health network characteristics and CVD risk factors: physical activity, hypertension, and smoking. A baseline survey asked questions about health networks using name generator questions that assessed who participants spoke to about health matters, whose opinions on healthcare mattered, and who they would trust to make healthcare decisions on their behalf. KEY RESULTS: Health networks were mainly comprised of family members and friends. Healthcare professionals comprised 7% of networks, mean network size was four, and 74% of health network contacts were perceived to be in "good" to "excellent" health. Persons with larger health networks had greater odds of being physically active compared with those with smaller networks (OR = 1.07, CI = 1.01-1.14). CONCLUSIONS: Health networks may be useful to intervention efforts for CVD risk factor reduction. More studies are needed to examine health networks in Caribbean contexts and explore associations with other CVD risk factors.

Information Loss in Harmonizing Granular Race and Ethnicity Data: Descriptive Study of Standards.

BACKGROUND: Data standards for race and ethnicity have significant implications for health equity research. OBJECTIVE: We aim to describe a challenge encountered when working with a multiple-race and ethnicity assessment in the Eastern Caribbean Health Outcomes Research Network (ECHORN), a research collaborative of Barbados, Puerto Rico, Trinidad and Tobago, and the US Virgin Islands. METHODS: We examined the data standards guiding harmonization of race and ethnicity data for multiracial and multiethnic populations, using the Office of Management and Budget (OMB) Statistical Policy Directive No. 15. RESULTS: Of 1211 participants in the ECHORN cohort study, 901 (74.40%) selected 1 racial category. Of those that selected 1 category, 13.0% (117/901) selected Caribbean; 6.4% (58/901), Puerto Rican or Boricua; and 13.5% (122/901), the mixed or multiracial category. A total of 17.84% (216/1211) of participants selected 2 or more categories, with 15.19% (184/1211) selecting 2 categories and 2.64% (32/1211) selecting 3 or more categories. With aggregation of ECHORN data into OMB categories, 27.91% (338/1211) of the participants can be placed in the "more than one race" category. CONCLUSIONS: This analysis exposes the fundamental informatics challenges that current race and ethnicity data standards present to meaningful collection, organization, and dissemination of granular data about subgroup populations in diverse and marginalized communities. Current standards should reflect the science of measuring race and ethnicity and the need for multidisciplinary teams to improve evolving standards throughout the data life cycle.

The impacts of parent-child communication on left-behind children's mental health and suicidal ideation: A cross sectional study in Anhui.

This study aimed to investigate the impact of previous maternal migration experiences on left-behind children's (LBC) mental health status and suicidal ideation, and the possible mediating role of parent-child communication. A cross-sectional study among rural children was conducted in Anhui, China, in 2018. LBC who self-reported that (a) their fathers were migrants and (b) they were living with their mothers at the time of the survey were included in this study. The participants were then divided into two subgroups by previous maternal migration experience. Previous maternal migration was associated with worse mental health and a higher prevalence of suicidal ideation among LBC compared with their peers. Healthy communication between children and parents fully mediates the adverse effects caused by previous maternal migration experiences on mental health among LBC, and communication with mother partially mediates the association with suicidal ideation. Communication classes for returning parents offered jointly by governments and schools could be an effective way to mitigate the impacts of maternal migration on child mental health and should be studied.

Recruitment and disruption of ventral pallidal cue encoding during alcohol seeking.

A critical area of inquiry in the neurobiology of alcohol abuse is the mechanism by which cues gain the ability to elicit alcohol use. Previously, we found that cue-evoked activity in rat ventral pallidum robustly encodes the value of sucrose cues trained under both Pavlovian and instrumental contingencies, despite a stronger relationship between cue-evoked activity and behavioral latency after instrumental training (Richard et al., 2018, Elife, 7, e33107). Here, we assessed: (a) ventral pallidal representations of Pavlovian versus instrumental cues trained with alcohol reward, and (b) the impact of non-associative alcohol exposure on ventral pallidal representations of sucrose cues. Decoding of cue identity based on ventral pallidum firing was blunted for the Pavlovian alcohol cue in comparison to both the instrumental cue trained with alcohol and either cue type trained with sucrose. Further, non-associative alcohol exposure had opposing effects on ventral pallidal encoding of sucrose cues trained on instrumental versus Pavlovian associations, enhancing decoding accuracy for an instrumental discriminative stimulus and reducing decoding accuracy for a Pavlovian conditioned stimulus. These findings suggest that alcohol exposure can drive biased engagement of specific reward-related signals in the ventral pallidum.

Measuring Exposure to Incarceration Using the Electronic Health Record.

BACKGROUND: Electronic health records (EHRs) are a rich source of health information; however social determinants of health, including incarceration, and how they impact health and health care disparities can be hard to extract. OBJECTIVE: The main objective of this study was to compare sensitivity and specificity of patient self-report with various methods of identifying incarceration exposure using the EHR. RESEARCH DESIGN: Validation study using multiple data sources and types. SUBJECTS: Participants of the Veterans Aging Cohort Study (VACS), a national observational cohort based on data from the Veterans Health Administration (VHA) EHR that includes all human immunodeficiency virus-infected patients in care (47,805) and uninfected patients (99,060) matched on region, age, race/ethnicity, and sex. MEASURES AND DATA SOURCES: Self-reported incarceration history compared with: (1) linked VHA EHR data to administrative data from a state Department of Correction (DOC), (2) linked VHA EHR data to administrative data on incarceration from Centers for Medicare and Medicaid Services (CMS), (3) VHA EHR-specific identifier codes indicative of receipt of VHA incarceration reentry services, and (4) natural language processing (NLP) in unstructured text in VHA EHR. RESULTS: Linking the EHR to DOC data: sensitivity 2.5%, specificity 100%; linking the EHR to CMS data: sensitivity 7.9%, specificity 99.3%; VHA EHR-specific identifier for receipt of reentry services: sensitivity 7.3%, specificity 98.9%; and NLP, sensitivity 63.5%, specificity 95.9%. CONCLUSIONS: NLP tools hold promise as a feasible and valid method to identify individuals with exposure to incarceration in EHR. Future work should expand this approach using a larger body of documents and refinement of the methods, which may further improve operating characteristics of this method.

The Share Project: Building Capacity of Justice-Involved Individuals, Policymakers, and Researchers to Collectively Transform Health Care Delivery.

The Share Project (TSP), a US health justice initiative, convened key stakeholders to advance the use of inclusive research methods and data sharing to engage groups that are typically marginalized from research. TSP trained justice-involved patients, community health workers, policymakers, and researchers in participatory research and the use of a data-sharing platform developed with justice-involved patients. The platform allowed users to analyze health and criminal justice data to develop new research that is patient driven and responsive to the needs of providers.
