"I felt like a freak when I would go to the doctor": Investigating healthcare experiences across the lifespan among older LGBT and transgender/gender diverse adults.

In the past several decades, the United States has enacted civil rights legislation protecting lesbian, gay, bisexual, transgender, and queer (LGBTQ) populations from discrimination, including enacting proactive healthcare laws such as the Affordable Care Act. However, given today's divisive politics, LGBTQ people's access to appropriate and respectful health care is precarious. This study explored the disconnections from and connections to health care and the respective health effects among two self-identified groups: i) older LGBT adults and ii) transgender and gender-diverse (TG/GD) adults. Using a life course perspective, qualitative data from 17 older LGBT and TG/GD participants were analyzed. Thematic and content analyses indicated that despite progress made, discrimination and prejudice in obtaining health care persist, particularly among TG/GD people of color. The results highlight the ongoing challenges LGBTQ populations face as they risk being denied care by healthcare providers and disconnected from the healthcare system.

Mapping the Dynamic Complexity of Sexual and Gender Minority Healthcare Disparities: A Systems Thinking Approach.

Sexual and gender minority (SGM) populations experience extensive health disparities compared to their straight and cisgender counterparts. The importance of addressing these disparities is paramount, as SGM groups often encounter significant barriers to accessing comprehensive healthcare, including societal stigma, provider bias, and financial constraints. This study utilizes a community-based system dynamics approach to understand and visualize the barriers to and facilitators of healthcare engagement for SGM groups across their life course. It aims to identify core constructs, relationships, and dynamic feedback mechanisms related to the experiences of connection/disconnection with physical, mental, and dental healthcare of SGM individuals. Barriers to access, such as discriminatory practices and the limited availability of SGM-informed healthcare professionals, exacerbate these disparities, underscoring the urgency of developing targeted interventions. System dynamics, a complex systems science (CSS) methodology, was used for this research. Group model building sessions were conducted with diverse SGM groups, including youth, older adults, and trans and gender-expansive community members. Causal loop diagrams were developed according to an iterative process, and a meta-model of their collective experiences was created. The study revealed extensive, dynamic, and shifting structural barriers for SGM community members accessing healthcare. Societal and structural stigma, provider bias, and pathologization were identified as significant barriers throughout their life course. Community-led interventions and SGM-focused holistic healthcare were identified as critical facilitators of SGM healthcare connection. The findings highlight the need for SGM-affirming and culturally responsive healthcare settings. This paper calls for a concerted effort from SGM health researchers to use CSS in developing interventions to reduce SGM health disparities.

Historic redlining and health outcomes: A systematic review.

OBJECTIVE: The purpose of this systematic review was to synthesize the existing literature on the associations between historic redlining and modern-day health outcomes across the lifespan. METHOD: This review searched PubMed and CINAHL for peer-reviewed, data-based articles examining the relationship between historic redlining and any health outcome. Articles were appraised using the JBI critical appraisal checklist. The results were synthesized using a narrative summary approach. RESULTS: Thirty-six articles were included and focused on various health outcomes, including cardiovascular outcomes, breast cancer incidence and mortality, firearm injury or death, birth-related outcomes, and asthma outcomes. Most of the included articles (n = 31; 86%) found significant associations between historic redlining and adverse health outcomes such as increased cardiovascular disease, higher rates of preterm births, increased cancer incidence, reduced survival time after breast cancer diagnosis, and increased firearm injury incidence. DISCUSSION: This review demonstrates the persistent effect of historic redlining on individuals' health. Public health nurses should recognize redlining as a form of structural racism when caring for affected communities and should advocate for policies and programs that advance health equity. Nurse researchers should develop and test multilevel interventions to address systemic racism and improve health outcomes in communities affected by redlining.

Social Activity Restriction and Psychological Health Among Caregivers of Older Adults With and Without Dementia.

OBJECTIVES: We examined associations between social activity restriction and psychological distress and well-being for caregivers of older adults with and without dementia, and if the identified associations are different for the two groups. METHODS: Using data from the 2017 National Study of Caregiving, we identified caregivers of older adults with (N = 541) and without (N = 1701) dementia. Linear regression models were estimated, adjusting for caregivers' age, gender, race, education, relationship to care recipient, and self-rated health. RESULTS: Restriction in visiting friends and family and attending religious services were associated with higher distress in dementia caregivers. Restriction in visiting friends and family was associated with higher distress and lower well-being in non-dementia caregivers. Any activity restriction had stronger association with distress for caregivers of older adults with versus without dementia. DISCUSSION: Findings highlight the need for tailored interventions based on caregivers' perceptions of meaningful social activities and dementia-friendly communities to promote social participation.

Multimodal smoking cessation treatment combining transcranial magnetic stimulation, cognitive behavioral therapy, and nicotine replacement therapy in veterans with posttraumatic stress disorder: A feasibility randomized controlled trial protocol.

Tobacco-related deaths exceed those resulting from homicides, suicides, motor vehicle accidence, alcohol consumption, illicit substance use, and acquired immunodeficiency syndrome (AIDS), combined. Amongst U.S. veterans, this trend is particularly concerning given that those suffering from posttraumatic stress disorder (PTSD)-about 11% of those receiving care from the Department of Veterans Affairs (VA)-have triple the risk of developing tobacco use disorder (TUD). The most efficacious strategies being used at the VA for smoking cessation only result in a 23% abstinence rate, and veterans with PTSD only achieve a 4.5% abstinence rate. Therefore, there is a critical need to develop more effective treatments for smoking cessation. Recent studies have revealed the insula as integrally involved in the neurocircuitry of TUD, specifically showing that individuals with brain lesions involving this region had drastically improved quit rates. Some of these studies show a probability of quitting up to 5 times greater compared to non-insula lesioned regions). Altered activity of the insula may be involved in the disruption of the salience network's (SN) connectivity to the executive control network (ECN), which compromises that patient's ability to switch between interoceptive states focused on cravings to executive and cognitive control. Thus, we propose a feasibility phase II randomized controlled trial (RCT) to study a patterned form of repetitive transcranial magnetic stimulation (rTMS), intermittent theta burst stimulation (iTBS), at 90% of the subject's resting motor threshold (rMT) applied over a region in the right post-central gyrus most functionally connected to the right posterior insula. We hypothesize that by increasing functional connectivity between the SN with the ECN to enhance executive control and by decreasing connectivity with the default mode network (DMN) to reduce interoceptive focus on withdrawal symptoms, we will improve smoking cessation outcomes. Fifty eligible veterans with comorbid TUD and PTSD will be randomly assigned to two conditions: active-iTBS + cognitive behavioral therapy (CBT) + nicotine replacement therapy (NRT) (n=25) or sham-iTBS + CBT + NRT (n=25). The primary outcome, feasibility, will be determined by achieving a recruitment of 50 participants and retention rate of 80%. The success of iTBS will be evaluated through self-reported nicotine use, cravings, withdrawal symptoms, and abstinence following quit date (confirmed by bioverification) along with evaluation for target engagement through neuroimaging changes, specifically connectivity differences between the insula and other regions of interest.

Impact of risk for severe COVID-19 illness on physical activity during the pandemic.

BACKGROUND: Precautions to mitigate spread of COVID-19 such as the closing of exercise facilities impacted physical activity behaviors. Varied risks for severe COVID-19 may have influenced participation in regular physical activity to maintain precautions. OBJECTIVE: Describe differences in the amount and intensity of physical activity between adults at high versus low risk for severe COVID-19 illness during the pandemic. We hypothesized that over 13 months, 1) high-risk adults would have greater odds of inactivity than low-risk adults, and 2) when active, high-risk adults would have lower metabolic equivalent of task minutes (MET-min) than low-risk adults. METHODS: This longitudinal observational cohort study surveyed U.S. adults' demographics, health history, and physical activity beginning March 2020 using REDCap. Using self-report, health history was assessed with a modified Charlson Comorbidity Index and physical activity with the International Physical Activity Questionnaire. Repeated physical activity measurements were conducted in June, July, October, and December of 2020, and in April of 2021. Two models, a logistic model evaluating physical inactivity (hypothesis 1) and a gamma model evaluating total MET-min for physically active individuals (hypothesis 2), were used. Models were controlled for age, gender, and race. RESULTS: The final sample consisted of 640 participants (mean age 42.7 ± 15.7, 78% women, 90% white), with n = 175 categorized as high-risk and n = 465 as low-risk. The odds of inactivity for the high-risk adults were 2.8 to 4.1 times as high than for low-risk adults at baseline and 13 months. Active high-risk adults had lower MET-min levels than low-risk adults in March (28%, p = 0.001), June (29%, p = 0.002), and July of 2020 (30%, p = 0.005) only. CONCLUSIONS: Adults at high risk of severe COVID-19 illness were disproportionately more likely to be physically inactive and exhibit lower MET-min levels than adults at low risk during the early months of the COVID-19 pandemic.

Cancer burden in women with HIV on Medicaid: A nationwide analysis.

BACKGROUND: Cancer is the leading cause of death in people living with HIV. In the United States, nearly 1 in 4 people living with HIV are women, more than half of whom rely on Medicaid for healthcare coverage. OBJECTIVE: The objective of this study is to evaluate the cancer burden of women living with HIV on Medicaid. DESIGN: We conducted a cross-sectional study of women 18-64 years of age enrolled in Medicaid during 2012, using data from Medicaid Analytic eXtract files. METHODS: Using International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes, we identified women living with HIV (n = 72,508) and women without HIV (n = 17,353,963), flagging the presence of 15 types of cancer and differentiating between AIDS-defining cancers and non-AIDS-defining cancers. We obtained adjusted prevalence ratios and 95% confidence intervals for each cancer and for all cancers combined, using multivariable log-binomial models, and additionally stratifying by age and race/ethnicity. RESULTS: The highest adjusted prevalence ratios were observed for Kaposi's sarcoma (81.79 (95% confidence interval: 57.11-117.22)) and non-Hodgkin's lymphoma (27.69 (21.67-35.39)). The adjusted prevalence ratios for anal and cervical cancer, both of which were human papillomavirus-associated cancers, were 19.31 (17.33-21.51) and 4.20 (3.90-4.52), respectively. Among women living with HIV, the adjusted prevalence ratio for all cancer types combined was about two-fold higher (1.99 (1.86-2.14)) in women 45-64 years of age than in women 18-44 years of age. For non-AIDS-defining cancers but not for AIDS-defining cancers, the adjusted prevalence ratios were higher in older than in younger women. There was no significant difference in the adjusted prevalence ratios for all cancer types combined in the race/ethnicity-stratified analyses of the women living with HIV cohort. However, in cancer type-specific sub-analyses, differences in adjusted prevalence ratios between Hispanic versus non-Hispanic women were observed. For example, the adjusted prevalence ratio for Hispanic women for non-Hodgkin's lymphoma was 2.00 (1.30-3.07) and 0.73 (0.58-0.92), respectively, for breast cancer. CONCLUSION: Compared to their counterparts without HIV, women living with HIV on Medicaid have excess prevalence of cervical and anal cancers, both of which are human papillomavirus related, as well as Kaposi's sarcoma and lymphoma. Older age is also associated with increased burden of non-AIDS-defining cancers in women living with HIV. Our findings emphasize the need for not only cancer screening among women living with HIV but also for efforts to increase human papillomavirus vaccination among all eligible individuals.

Successful Utilization of Resuscitative Endovascular Balloon Occlusion of the Aorta in a Pediatric Patient.

In the United States, pediatric trauma resulting in traumatic brain injury (TBI) and massive hemorrhage is the leading cause of death. Although use of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) continues to gain favor, limited data exists on use and efficacy in pediatric patients. We describe a case using REBOA in a pediatric patient with blunt abdominal injury causing hemorrhagic shock. A 14-year-old female presented via air to a level 1 trauma center post motor vehicle collision with prolonged extraction. At landing, she was hemodynamically unstable with GCS and vitals indicating severe injuries. Further assessment indicated REBOA catheter placement with advancement to zone 1. Upon surgical stabilization, REBOA was deflated and distal pulses were maintained without complication. In cases where massive hemorrhage is the major threat to survival, REBOA may improve outcomes. Unfortunately, this patient had sustained a nonsurvivable TBI, and the family decided upon organ donation.

Sustained overexpression of spliced X-box-binding protein-1 in neurons leads to spontaneous seizures and sudden death in mice.

The underlying etiologies of seizures are highly heterogeneous and remain incompletely understood. While studying the unfolded protein response (UPR) pathways in the brain, we unexpectedly discovered that transgenic mice (XBP1s-TG) expressing spliced X-box-binding protein-1 (Xbp1s), a key effector of UPR signaling, in forebrain excitatory neurons, rapidly develop neurologic deficits, most notably recurrent spontaneous seizures. This seizure phenotype begins around 8 days after Xbp1s transgene expression is induced in XBP1s-TG mice, and by approximately 14 days post induction, the seizures evolve into status epilepticus with nearly continuous seizure activity followed by sudden death. Animal death is likely due to severe seizures because the anticonvulsant valproic acid could significantly prolong the lives of XBP1s-TG mice. Mechanistically, our gene profiling analysis indicates that compared to control mice, XBP1s-TG mice exhibit 591 differentially regulated genes (mostly upregulated) in the brain, including several GABAA receptor genes that are notably downregulated. Finally, whole-cell patch clamp analysis reveals a significant reduction in both spontaneous and tonic GABAergic inhibitory responses in Xbp1s-expressing neurons. Taken together, our findings unravel a link between XBP1s signaling and seizure occurrence.

A systematic review of U.S. nursing faculty's knowledge, awareness, inclusion, and perceived importance of sexual and gender minority-related content in nursing curricula.

BACKGROUND: In the US, sexual and gender minority (SGM) individuals continue to experience health inequities, and nursing curricula content and nursing faculty with SGM health expertise in the US remain limited. Addressing health disparities begins with the preparation of future nurses-US nursing faculty must be supported to meet these growing needs. PURPOSE: To describe, appraise, and synthesize research from 2000-2020 on US nursing faculty knowledge, awareness, inclusion, and perceived importance of SGM health content. METHODS: Following PRISMA 2020 guidelines, we registered a systematic review and appraisal protocol in PROSPERO, and then executed the protocol and synthesized the literature. DISCUSSION: We found an empirical evidence base surrounding US nursing faculty and SGM health much more limited than expected. Only four cross-sectional, descriptive empirical articles fit the a priori inclusion criteria. The studies were of moderate quality at best and often relied on unvalidated or older measures. In general, the studies focused on examining characteristics of nursing programs, faculty comfort with content, faculty perceptions of content importance, and hours dedicated to content. CONCLUSION: Since the close of the review, new commentaries and editorials expanding the call for change in the US were published-the time for commentary has passed. It remains unclear whether US nursing faculty are adequately prepared to educate future nurses about SGM health issues-and an unprepared healthcare workforce is yet another barrier to SGM health equity. The evidence base supporting US nursing faculty development desperately needs more studies using rigorous methodologies.

Racial, ethnic and neighborhood socioeconomic differences in incidence of dementia: A regional retrospective cohort study.

BACKGROUND: Evidence on the effects of neighborhood socioeconomic disadvantage on dementia risk in racially and ethically diverse populations is limited. Our objective was to evaluate the relative extent to which neighborhood disadvantage accounts for racial/ethnic variation in dementia incidence rates. Secondarily, we evaluated the spatial relationship between neighborhood disadvantage and dementia risk. METHODS: In this retrospective study using electronic health records (EHR) at two regional health systems in Northeast Ohio, participants included 253,421 patients aged >60 years who had an outpatient primary care visit between January 1, 2005 and December 31, 2015. The date of the first qualifying visit served as the study baseline. Cumulative incidence of composite dementia outcome, defined as EHR-documented dementia diagnosis or dementia-related death, stratified by neighborhood socioeconomic deprivation (as measured by Area Deprivation Index) was determined by competing-risk regression analysis, with non-dementia-related death as the competing risk. Fine-Gray sub-distribution hazard ratios were determined for neighborhood socioeconomic deprivation, race/ethnicity, and clinical risk factors. The degree to which neighborhood socioeconomic position accounted for racial/ethnic disparities in the incidence of composite dementia outcome was evaluated via mediation analysis with Poisson rate models. RESULTS: Increasing neighborhood disadvantage was associated with increased risk of EHR-documented dementia diagnosis or dementia-related death (most vs. least disadvantaged ADI quintile HR = 1.76, 95% confidence interval = 1.69-1.84) after adjusting for age and sex. The effect of neighborhood disadvantage on this composite dementia outcome remained after accounting for known medical risk factors of dementia. Mediation analysis indicated that neighborhood disadvantage accounted for 34% and 29% of the elevated risk for composite dementia outcome in Hispanic and Black patients compared to White patients, respectively. CONCLUSION: Neighborhood disadvantage is related to the risk of EHR-documented dementia diagnosis or dementia-related death and accounts for a portion of racial/ethnic differences in dementia burden, even after adjustment for clinically important confounders.

Nursing pre-licensure and graduate education for LGBTQ health: A systematic review.

BACKGROUND: Lesbian, gay, bisexual, transgender, and queer plus (LGBTQ) people experience discrimination and health disparities compared to heterosexual cisgender people. Clinicians report discomfort and insufficient preparation for providing care to LGBTQ people and nursing has been slow to integrate LGBTQ health into curricula. PURPOSE: Conduct a systematic review to examine and critically appraise peer-reviewed literature on nursing student knowledge, skills, and attitudes (KSAs) regarding LGBTQ health and the development/evaluation of LGBTQ health content in nursing curricula. METHODS: A systematic review was conducted (N = 1275 articles from PubMed, LGBT Health, CINAHL, ERIC, and Health Source-Nursing/Academic Edition). FINDINGS: Twenty articles met inclusion criteria. Twelve studies described curricular interventions; however, there were few validated tools to evaluate content coverage or KSAs. Four themes emerged specific to LGBTQ health content inclusion. DISCUSSION: While an emerging science of LGBTQ nursing education has been identified, more work is needed to build and evaluate a comprehensive curricular approach for full programmatic integration of LGBTQ health. CONCLUSION: As nursing programs build LGBTQ content into nursing curricula, care must be taken to integrate this content fully with the depth of curricular content in population health, social determinants of health, social justice, intersectionality, cultural competence, and political advocacy. TWEETABLE ABSTRACT: Greater integration of LGBTQ health content into nursing education should be a priority for nursing education.

Socioeconomic correlates of health outcomes and mental health disparity in a sample of cancer patients during the COVID-19 pandemic.

AIMS AND OBJECTIVES: To investigate socioeconomic, behavioural and healthcare delivery factors that are associated with health outcomes of cancer patients during the COVID-19 pandemic, especially among underserved cancer patients. BACKGROUND: Cancer patients are at a higher risk of adverse physical and mental health outcomes during the pandemic than those without cancer. DESIGN: Cross-sectional online survey. We followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guidelines in this study. METHODS: The sample comprised 322 individuals diagnosed with incident cancer between January 2019 and January 2020. Demographically, 64% were female, 49% had a college degree, 12% were African American, and 88% were White (77% of the Whites were from metropolitan and 23% from nonmetropolitan areas). Descriptive analysis and multivariable regression analyses of global health status, depression and irritability were performed. RESULTS: After adjusting for demographic variables and comorbidity, the feelings of loneliness, crowded living space, lower confidence in taking preventive measures and less satisfaction with telehealth visits were significantly associated with poorer global health, depression and irritability. Daily exercise was associated with better global health, and difficulty in getting medicine was associated with depression and irritability. Moreover, African Americans who felt lonely reported more depression and irritability and those who had less confidence in taking preventive measures reported more irritability than Whites. Respondents having low income and feeling lonely reported more depression than others. CONCLUSIONS: In this study, socioeconomic factors (e.g. loneliness or crowded living conditions) were as important to health outcomes during the pandemic as behavioural (e.g. prevention and exercises) and quality-of-care factors (e.g. telehealth, access to medicine). Disparity was more pronounced in the mental health of African Americans and those with low incomes. RELEVANCE TO CLINICAL PRACTICE: Healthcare providers should promote social support and physical activity for improving health and reducing mental health disparities among cancer patients.

Digital Medicine System in Veterans With Severe Mental Illness: Feasibility and Acceptability Study.

BACKGROUND: Suboptimal medication adherence is a significant problem for patients with serious mental illness. Measuring medication adherence through subjective and objective measures can be challenging, time-consuming, and inaccurate. OBJECTIVE: The primary purpose of this feasibility and acceptability study was to evaluate the impact of a digital medicine system (DMS) among Veterans (patients) with serious mental illness as compared with treatment as usual (TAU) on medication adherence. METHODS: This open-label, 2-site, provider-randomized trial assessed aripiprazole refill adherence in Veterans with schizophrenia, schizoaffective disorder, bipolar disorder, or major depressive disorder. We randomized 26 providers such that their patients either received TAU or DMS for a period of 90 days. Semistructured interviews with patients and providers were used to examine the feasibility and acceptability of using the DMS. RESULTS: We enrolled 46 patients across 2 Veterans Health Administration sites: 21 (46%) in DMS and 25 (54%) in TAU. There was no difference in the proportion of days covered by medication refill over 3 and 6 months (0.82, SD 0.24 and 0.75, SD 0.26 in DMS vs 0.86, SD 0.19 and 0.82, SD 0.21 in TAU, respectively). The DMS arm had 0.85 (SD 0.20) proportion of days covered during the period they were engaged with the DMS (mean 144, SD 100 days). Interviews with patients (n=14) and providers (n=5) elicited themes salient to using the DMS. Patient findings described the positive impact of the DMS on medication adherence, challenges with the DMS patch connectivity and skin irritation, and challenges with the DMS app that affected overall use. Providers described an overall interest in using a DMS as an objective measure to support medication adherence in their patients. However, providers described challenges with the DMS dashboard and integrating DMS data into their workflow, which decreased the usability of the DMS for providers. CONCLUSIONS: There was no observed difference in refill rates. Among those who engaged in the DMS arm, the proportion of days covered by refills were relatively high (mean 0.85, SD 0.20). The qualitative analyses highlighted areas for further refinement of the DMS. TRIAL REGISTRATION: ClinicalTrials.gov NCT03881449; https://clinicaltrials.gov/ct2/show/NCT03881449.

Telehealth in Trans and Gender Diverse Communities: the Impact of COVID-19.

Purpose of Review: This paper synthesizes current knowledge regarding telehealth and the impact of the SARS-COV2 pandemic on transgender and gender diverse (TGD) patients. We discuss the benefits and challenges of telehealth for patients, providers, and trainees. Recent Findings: Mental health of TGD populations has been disproportionately challenged in the context of SARS-COV2, and telehealth interventions focused on gender affirmation and mental health are desired and acceptable by TGD populations. Summary: Telehealth in the era of SARS-COV-2 has a mixed impact on TGD patients and families, increasing access, decreasing travel time, and allowing for comfort and safety during care while also leaving gaps in care for patients without web/phone access and/or without a confidential place to participate in appointments, or to manage health concerns that require in-person evaluation. Providers have benefitted from the ability to reach TGD patients that are far from practice sites and to provide remote consultation for procedures and other interventions. Trainees have challenges as a result of telehealth practice which can impair the ability to learn in-person care, but have benefitted from remote training opportunities, including surgical training. Alterations in compensation structures have allowed sustainable telehealth practice to be an option for providers and health systems. As telehealth evolves, quality improvement and research efforts aimed at resolving known challenges and expanding beneficial uses of telehealth should consistently include and consider not only the beneficiaries of telehealth but also those who may struggle with access.

How can the nursing profession help reduce sexual and gender minority related health disparities: Recommendations from the National Nursing LGBTQ Health Summit.

BACKGROUND: Lesbian, gay, bisexual, transgender and queer (LGBTQ) people, also commonly referred to as sexual and gender minorities (SGMs), live in every part of the United States and encompass all races and/or ethnicities, religions, and social classes. Major reports from various sources document higher rates of health issues (e.g., substance abuse, depression, suicidality, cardiovascular disease) among SGMs than heterosexuals. Chronic stress related to marginalization and discrimination is a key contributor to these disparities. The nursing profession has paid relatively little attention to SGM health issues. PURPOSE AND METHODS: To address these gaps, the first National Nursing LGBTQ Health Summit brought together nursing deans, leaders of national nursing organizations, and other participants from across the United States. FINDINGS: Participants agreed that increasing SGM-specific content in nursing curricula, practice guidelines, faculty development, and research is necessary to improve the health of SGM people. DISCUSSION: The Summit ended with a call to action for the nursing profession to prioritize SGM health through innovations in education, research, and practice.

Low initial in-hospital end-tidal carbon dioxide predicts poor patient outcomes and is a useful trauma bay adjunct.

INTRODUCTION: Appropriate triage of the trauma patient is critical. Low end-tidal carbon dioxide (ETCO2) is associated with mortality and hemorrhagic shock in trauma, but the relationship between low ETCO2 and important clinical variables is not known. This study investigates the association of initial in-hospital ETCO2 and patient outcomes, as well as the utility of ETCO2 as a predictive aid for blood transfusion. METHODS: Adult patients who presented to a Level One trauma center from 2019 to 2020 were eligible. Trauma bay ETCO2 measured by side-stream capnography was prospectively obtained for all trauma activations at time of initial evaluation. Using the Liu method of cut point estimation, patients were stratified as having low (≤29.5 mmHg) or normal ETCO2 (>29.5 mmHg). Multivariable regression was used to estimate the association of low ETCO2 with patient outcomes. RESULTS: A total of 955 patients underwent initial in-hospital ETCO2 measurement. Median time from arrival to ETCO2 measurement was 4 min. Among admitted patients (N = 493), 48.9% had low ETCO2. Compared to patients with normal ETCO2, those with low ETCO2 were older (median age 53 vs 46, p = 0.01) and more likely to have the highest trauma activation (27.4% vs 19.8%, p = 0.048). There was no difference in head injury. After adjustment, patients with low ETCO2 had greater odds of blood transfusion (OR 4.65, 95%CI 2.0-10.7), mortality (OR 5.10, 95%CI 1.1-24.9), inferior disposition (OR 1.64, 95%CI 1.1-2.6), and complications (OR 3.35, 95%CI 1.5-7.4). ETCO2 was more predictive of early blood transfusion than Shock Index (area under ROC = 67.6% vs 58.2%). CONCLUSIONS: Low trauma bay ETCO2 remains significantly associated with inferior clinical outcomes after adjustment. In comparison to other triage tools, low ETCO2 values may be more predictive of the need for blood transfusion. Further studies are needed to evaluate the role of ETCO2 as a decision making tool for early trauma management.

Post-Mortem CT Delivers Fast and Accurate Injury Identification in Trauma Patients.

BACKGROUND: Accurate and timely injury identification is critical but difficult to achieve in trauma patients who die shortly after arrival to the hospital. Autopsy has historically been used to detect injuries, but few undergo formal autopsy. This study investigates the utility of post-mortem computed tomography (PMCT) for injury identification in a diverse trauma population. METHODS: Cross-sectional study of adult trauma patients who died within 24 hours of arrival to a Level I trauma center were included. Among patients with PMCT, injury severity score (ISS) and number of injuries (NOI) were calculated either from physical exam alone (pre-PMCT) or exam and imaging (post-PMCT). ISS and NOI before and after PMCT were compared. A cause of death analysis was performed for patients who underwent comprehensive (ie, head, neck, and torso) PMCT. Non-parametric repeated measures tests were used, as appropriate. RESULTS: 7.3% (N = 28) of patients received PMCT. Compared to pre-PMCT, median ISS (21 vs 3.5) and NOI (5 vs 2) were greater post-PMCT (P < .001, respectively). Autopsy rate was 13.2% overall; 82.5% of autopsies were due to a penetrating mechanism, and median time to autopsy reporting was 38.5 days. Among 17 patients who received comprehensive PMCT, 64.7% had a single cause of death identified, and the remaining were classified as either multiple potential contributors or unknown. DISCUSSION: PMCT is a readily available method to identify injuries in trauma patients who expire shortly upon presentation. Given the low autopsy rate for blunt trauma and delay in reporting, PMCT is an important adjunct for trauma providers.

Excess cancer prevalence in men with HIV: A nationwide analysis of Medicaid data.

BACKGROUND: Cancer is one of the most common comorbidities in men living with HIV (MLWH). However, little is known about the MLWH subgroups with the highest cancer burden to which cancer prevention efforts should be targeted. Because Medicaid is the most important source of insurance for MLWH, we evaluated the excess cancer prevalence in MLWH on Medicaid relative to their non-HIV counterparts. METHODS: In this cross-sectional study using 2012 Medicaid Analytic eXtract data nationwide, we flagged the presence of HIV, 13 types of cancer, symptomatic HIV, and viral coinfections using codes from the International Classification of Diseases, Ninth Revision, Clinical Modification. The study population included individuals administratively noted to be of male sex (men), aged 18 to 64 years, with (n = 82,495) or without (n = 7,302,523) HIV. We developed log-binomial models with cancer as the outcome stratified by symptomatic status, age, and race/ethnicity. RESULTS: Cancer prevalence was higher in MLWH than in men without HIV (adjusted prevalence ratio [APR], 1.84; 95% confidence interval [CI], 1.78-1.90) and was higher among those with symptomatic HIV (APR, 2.74; 95% CI, 2.52-2.97) than among those with asymptomatic HIV (APR, 1.73; 95% CI, 1.67-1.79). The highest APRs were observed for anal cancer in younger men, both in the symptomatic and asymptomatic groups: APR, 312.97; 95% CI, 210.27-465.84, and APR, 482.26; 95% CI, 390.67-595.32, respectively. In race/ethnicity strata, the highest APRs were among Hispanic men for anal cancer (APR, 198.53; 95% CI, 144.54-272.68) and for lymphoma (APR, 9.10; 95% CI, 7.80-10.63). CONCLUSIONS: Given the Medicaid program's role in insuring MLWH, the current findings highlight the importance of the program's efforts to promote healthy behaviors and vaccination against human papillomavirus in all children and adolescents and to provide individualized cancer screening for MLWH.
