RESUMO

OBJECTIVE: To automate the generation of three validated nephrometry scoring systems on preoperative computerised tomography (CT) scans by developing artificial intelligence (AI)-based image processing methods. Subsequently, we aimed to evaluate the ability of these scores to predict meaningful pathological and perioperative outcomes. PATIENTS AND METHODS: A total of 300 patients with preoperative CT with early arterial contrast phase were identified from a cohort of 544 consecutive patients undergoing surgical extirpation for suspected renal cancer. A deep neural network approach was used to automatically segment kidneys and tumours, and then geometric algorithms were used to measure the components of the concordance index (C-Index), Preoperative Aspects and Dimensions Used for an Anatomical classification of renal tumours (PADUA), and tumour contact surface area (CSA) nephrometry scores. Human scores were independently calculated by medical personnel blinded to the AI scores. AI and human score agreement was assessed using linear regression and predictive abilities for meaningful outcomes were assessed using logistic regression and receiver operating characteristic curve analyses. RESULTS: The median (interquartile range) age was 60 (51-68) years, and 40% were female. The median tumour size was 4.2 cm and 91.3% had malignant tumours. In all, 27% of the tumours were high stage, 37% high grade, and 63% of the patients underwent partial nephrectomy. There was significant agreement between human and AI scores on linear regression analyses (R ranged from 0.574 to 0.828, all P < 0.001). The AI-generated scores were equivalent or superior to human-generated scores for all examined outcomes including high-grade histology, high-stage tumour, indolent tumour, pathological tumour necrosis, and radical nephrectomy (vs partial nephrectomy) surgical approach. CONCLUSIONS: Fully automated AI-generated C-Index, PADUA, and tumour CSA nephrometry scores are similar to human-generated scores and predict a wide variety of meaningful outcomes. Once validated, our results suggest that AI-generated nephrometry scores could be delivered automatically from a preoperative CT scan to a clinician and patient at the point of care to aid in decision making.

RESUMO

INTRODUCTION: For adult trauma patients, the likelihood of receiving treatment at a hospital properly equipped for trauma care can vary by race and sex. This study examines whether a pediatric patient's race/ethnicity and sex are associated with treatment at a high acuity trauma hospital (HATH). MATERIALS AND METHODS: Using the 2017 National Inpatient Sample, we identified pediatric trauma patients ( ≤16 y) using International Classification of Diseases-10 codes. Because trauma centers are not defined in National Inpatient Sample, we defined HATHs as hospitals which transferred 0% of pediatric neurotrauma. We used logistic regression to examine associations between race/ethnicity, sex, age, and treatment at a HATH, adjusted for factors including Injury Severity Score, mechanism of injury, and region. RESULTS: Of 18,085 injured children (median Injury Severity Score 3 [IQR 1-8]), 67% were admitted to a HATH. Compared to White patients, Hispanic (odds ratio [OR] 0.85 [95% confidence interval [CI] 0.79-0.93]) and other race/ethnicity patients (OR 0.85 [95% CI 0.78-0.93]) had a significantly lower odds of treatment at a HATH. Children aged 2-11 (OR 1.36 [95% CI 1.27-1.46]) were more likely to be treated at a HATH compared to adolescents (age 12-16). After adjustment for other factors, sex was not associated with treatment at a HATH. CONCLUSIONS: Our study demonstrated racial and ethnic disparities in access to HATHs for pediatric trauma patients. Hispanic and other race/ethnicity pediatric trauma patients have lower odds of treatment at HATHs. Further research is needed to study the root causes of these disparities to ensure that all children with injuries receive equitable and high-quality care.

RESUMO

The preponderance of HIV interventions have been behavioral, targeting individual, dyadic, or group dynamics. However, structural-level interventions are required to decrease HIV transmission and increase engagement in care, especially for men who have sex with men (MSM), particularly Black and Latinx MSM. A systematic literature review was conducted to assess the current state of structural interventions; only two studies detailing structural interventions related to HIV for Black and Latinx MSM in the US were identified. An additional 91 studies which discussed structural-level barriers to optimal HIV outcomes among MSM, yet which did not directly evaluate a structural intervention, were also identified. While this paucity of findings was discouraging, it was not unexpected. Results of the systematic review were used to inform guidelines for the implementation and evaluation of structural interventions to address HIV among MSM in the U.S. These include deploying specific interventions for multiply marginalized individuals, prioritizing the deconstruction of structural stigma, and expanding the capacity of researchers to evaluate "natural" policy-level structural interventions through a standardization of methods for rapid evaluative response, and through universal application of sex, sexual orientation, and gender identity demographic measures.

RESUMO

The ongoing COVID-19 pandemic has had widespread social, psychological, and economic impacts. However, these impacts are not distributed equally: already marginalized populations, specifically racial/ethnic minority groups and sexual and gender minority populations, may be more likely to suffer the effects of COVID-19. The COVID-19 Resiliency Survey was conducted by the city of Chicago to assess the impact of COVID-19 on city residents in the wake of Chicago's initial lockdown, with particular focus on the experiences of minority populations. Chi-square tests of independence were performed to compare COVID-19-related outcomes and impacts on heterosexual vs. sexual minority populations, cisgender vs. gender minority populations, and White vs. racial/ethnic minority subgroups. Marginalized populations experienced significant disparities in COVID-19 exposure, susceptibility, and treatment access, as well as in psychosocial effects of the pandemic. Notably, Black and Latinx populations reported significant difficulties accessing food and supplies (p = 0.002). Healthcare access disparities were also visible, with Black and Latinx respondents reporting significantly lower levels of access to a provider to see if COVID-19 testing would be appropriate (p = 0.013), medical services (p = 0.001), and use of telehealth for mental health services (p = 0.001). Sexual minority respondents reported significantly lower rates of using telehealth for mental health services (p = 0.011), and gender minority respondents reported significantly lower levels of primary care provider access (p = 0.016). There are evident COVID-19 disparities experienced in Chicago especially for Black, Latinx, sexual minority, and gender minority groups. A greater focus must be paid to health equity, including providing increased resources and supplies for affected groups, adapting to inequities in the built environment, and ensuring adequate access to healthcare services to ameliorate the burden of COVID-19 on these marginalized populations.

RESUMO

Objectives. To comprehensively assess asthma disparities and identify correlates in youths at the intersections of sex, sexual identity, and race/ethnicity in the United States.Methods. We obtained a diverse sample of youths (n = 307 073) from the Centers for Disease Control and Prevention's Youth Risk Behavior Survey. We pooled data across 107 jurisdiction-years (2009-2017). We calculated lifetime asthma prevalence by sexual identity, race/ethnicity, and their intersections-stratified by sex. We developed multivariable weighted logistic regression models to examine the impact of selected correlates on lifetime asthma prevalence.Results. Lesbian, gay, and bisexual youths have significant disparities in asthma prevalence compared with heterosexual peers. Moreover, across sex, higher prevalence of lifetime asthma was seen for most sexual identity and race/ethnicity subpopulations (27 of 30) when compared with White heterosexual sex-matched participants. Selected traditional risk factors (overweight, obese, and smoking) and bullying tended to attenuate odds among groups, especially those with a minority sexual identity.Conclusions. Asthma inequities at the intersection of sexual identity and race/ethnicity are substantive. Future studies should investigate the mechanisms contributing to these disparities to promote health equity among vulnerable youth populations. (Am J Public Health.

RESUMO

HIV remains a serious concern among youth, particularly among sexual minority youth (SMY). Risk behaviors including low rates of HIV testing and inconsistent condom use as well as use of substances before sex contribute to these disparities. Therefore, HIV education in schools may be a valuable tool for reducing HIV-related risk behaviors. Using a large, pooled sample of youth (N = 169,468) from the 2009-2017 Youth Risk Behavior Survey (YRBS), we conducted the first population-level assessment of associations between HIV education and risk behavior prevalence among high school-aged youth by sexual behavior (i.e., sex of sexual partner [s]) in the USA. Results demonstrated that racial/ethnic minority youth and SMY were less likely to have received HIV education than White or heterosexual peers. HIV education was associated with less substance use at last sex. Among males, HIV education was associated with increased condom use and HIV testing, emphasizing its promise as a potential intervention for risk behavior reduction. Results are discussed in light of current literature with future recommendations.

RESUMO

BACKGROUND: Medical mistrust (MM) is seen as a barrier to assessing healthcare needs and addressing health disparities; however, limited literature has focused on assessing MM for vulnerable populations, especially racial/ethnic minority and sexual/gender minority youth and young adults (YYA). METHODS: Between February 2021 and March 2022, we conducted the Youth and Young Adults COVID-19 Study, a prospective cohort of minoritized YYA aged 14 to 24 years (n = 1027), within the United States and its territories. Participants were recruited through a combination of paid social media ads, outreach with organizations serving marginalized youth, and an existing registry, targeting racial and ethnic minority and LGBTQ + youth for a study on COVID-19 health behaviors. Multiple multinomial logistic regression models were developed to examine associations between demographics and three dimensions of MM including healthcare experience, government information, and scientific information. RESULTS: Most participants were between the ages of 18 and 21 years (48.3%), identified as Hispanic (33.3%) or white (22.5%), and bisexual or pansexual (34.3%). Queer YYA had higher odds of reporting worse personal healthcare experiences than their straight peers. The odds of gay/lesbian YYA that reported somewhat or extreme trust in doctor's sources were two times higher than their straight peers. Except for those who identified as Asian, racial/ethnic minority YYA were less likely to report somewhat or extreme trust in the CDC's general information or its COVID-19 data than white YYA. Transgender and gender diverse YYA were more than twice as likely to report being very or extremely influenced by statistics of the dangers of COVID-19 than cisgender YYA. CONCLUSIONS: Our study indicated the importance of incorporating marginalized identities into the assessment of medical mistrust to better understand YYA's health prevention and treatment behaviors and to develop public health prevention and treatment strategies, especially for minoritized communities.

RESUMO

Purpose: To assess whether the COVID-19 pandemic has inequitably impacted key social determinants of health (SDoH), specifically employment, housing, and health care, for U.S. transgender populations. Methods: Between April 13, 2020 and August 3, 2020, we conducted a national, cross-sectional online survey of sexual and gender minority individuals (N=870). We used logistic regression to calculate both unadjusted and adjusted odds of unemployment, homelessness/housing instability, and interruptions in medical care owing to the pandemic by gender and gender modality. Adjusted models controlled for age, race/ethnicity, and region. Results: In adjusted models, transgender and gender diverse people had 2.12 times the odds of reporting homelessness/housing instability and 2.88 times the odds of reporting medical care interruptions compared with cisgender peers. Transgender men, women, and nonbinary people had 4.12, 3.29, and 3.48 times the adjusted odds of interruptions in medical care compared with cisgender men, respectively. We did not observe significant differences in employment. Conclusions: Findings add empirical support to the hypothesis that socioeconomic consequences of COVID-19 are inequitably impacting transgender people. To contextualize our results and support future research in this area, we present a conceptual model of the short- and long-term impacts of COVID-19 on transgender populations using a framework of stigma as a fundamental cause of health inequities. Our findings emphasize that public health professionals must urgently consider-and intervene to address-the pandemic's SDoH-related impacts on transgender populations.

RESUMO

Transgender individuals are disproportionately affected by HIV in the United States. Given increased risk of HIV among youth, there is a need to understand HIV risk and protective factors among transgender individuals who are 18 years and younger. Patterns of HIV testing, HIV education, and condom use have known associations with HIV outcomes among youth in general, but are understudied among transgender youth. This study assessed these outcomes by developing a series of sex-stratified multivariable logistic regression models using pooled Youth Risk Behavior Survey data. Results indicate female and male transgender youth as well as males who were not sure they were transgender were more likely have tested for HIV compared with their not transgender peers. Male transgender youth were significantly less likely to have received HIV education compared with not transgender males. Females not sure if they were transgender and male transgender youth were significantly less likely to have used condoms compared with, respectively, not transgender female and not transgender male counterparts. In sum, condom use and HIV education both remain lower among transgender individuals relative to their not-transgender peers. This highlights the need for the promotion of culturally appropriate HIV education and HIV prevention supports among transgender youth.

RESUMO

INTRODUCTION: Sexual minority and/or racial/ethnic minority youth may use alcohol at school as a form of minority stress-based coping. Polyvictimization is particularly prevalent among sexual minority and/or racial/ethnic minority youth and may be a useful proxy measure for minority stressors. METHODS: Data from local administrations of the Youth Risk Behavior Survey were pooled across 42 jurisdiction years (biennially, 2009-2017) and analyzed in 2022, resulting in a sample of 118,052 U.S. youth. The prevalence of alcohol use at school was examined by sexual identity, race/ethnicity, and their intersections, stratified by sex. Multivariable logistic regression models were built to examine the disparities in alcohol use at school and the impact of school-based polyvictimization. RESULTS: At the intersections of race/ethnicity and sexual identity, 25 of 30 sexual minority and/or racial/ethnic minority subpopulations had greater odds of alcohol use at school than their White heterosexual same-sex peers. Hispanic/Latinx not-sure males (AOR=9.15; 95% CI=5.97, 14.03) and Hispanic/Latinx lesbian females (AOR=11.24; 95% CI=6.40, 19.77) were most likely to report alcohol use at school. After adjusting for polyvictimization, the magnitude of association was attenuated for most sexual minority and/or racial/ethnic minority subpopulations; however, all but 2 significant associations remained. CONCLUSIONS: Sexual minority and/or racial/ethnic minority youth were more likely than White heterosexual peers to use alcohol at school, with the greatest odds among multiply marginalized and polyvictimized youth. Interventions should consider addressing more than school-based victimization alone because disparities persisted, although at a lower magnitude, after accounting for polyvictimization. Future longitudinal studies are warranted to further explore the associations between multiply marginalized identities, school-based polyvictimization, and alcohol use at school.

RESUMO

Attaining equity in vaccination distribution is a moral and ethical goal that ensures all members of our community are properly cared for. We suggest a comprehensive approach that involves allocating community resources based on local economic, demographic, and COVID-19 infection data, removing technology barriers by staffing vaccine appointment call-in centers, distributing vaccines based on objective factors (eg, household density) rather than on a "first come, first served" basis, and creating pop-up vaccination sites at trusted community organizations such as federally qualified healthcare centers, churches, libraries, and barber/beauty shops. Until every community is safe, no community will be safe.

RESUMO

BACKGROUND: Sexual minority and racial/ethnic minority youth experience a higher burden of asthma. The frameworks of minority stress theory and intersectionality suggest that sexual minority and racial/ethnic minority youth may experience disparities in nonremitting asthma. OBJECTIVE: To examine adjusted odds of nonremitting asthma by sexual identity, race/ethnicity, and their intersections, along with their relationship with traditional nonremitting asthma risk factors (weight status and smoking) and victimization (bullying, cyberbullying, and forced sex). METHODS: We used data from the Youth Risk Behavior Survey pooled across 41 jurisdiction-years (biennially, 2009-2017), resulting in a sample of 21,789 US youth. The prevalence of nonremitting asthma was examined by sexual identity, race/ethnicity, and their intersections, stratified by sex. Bivariate associations and backward logistic regression models, stratified by sex, were built to examine nonremitting asthma disparities and the effects of selected traditional correlates and victimization variables. RESULTS: At the intersections, 8 sexual minority and racial/ethnic minority subpopulations were significantly more likely to have nonremitting asthma compared with White heterosexual sex-matched peers. White gay males and Black lesbian females had the highest odds of nonremitting asthma. Traditional risks of nonremitting asthma and victimization were associated with attenuated odds of nonremitting asthma. CONCLUSIONS: Many sexual minority and racial/ethnic youth subpopulations are more likely to have nonremitting asthma. Evidence suggests that traditional nonremitting asthma risk factors and victimization may partly explain disparities in nonremitting asthma. Asthma management guidelines should be updated to include population health disparities of sexual and racial/ethnic minorities.

RESUMO

Sexual and gender minority (SGM) populations may be affected disproportionately by health emergencies such as the coronavirus disease 2019 (COVID-19) pandemic. Health professionals must take immediate steps to ensure equitable treatment of SGM populations. These steps are to (1) maintain and increase cultural responsiveness training and preparedness for SGM populations, (2) increase use of sexual orientation and gender identity measures in surveillance, (3) conduct research on the impacts of COVID-19 on SGM populations, and (4) include equity-focused initiatives in disaster preparedness plans. These actions toward equity would begin to allow for our current health system to care more appropriately for SGM populations.
