A survey of oncology advanced practice providers' knowledge and attitudes towards sexual and gender minorities with cancer
AIMS AND OBJECTIVES/OBJECTIVE:To evaluate the knowledge and attitudes towards sexual and gender minority (SGM) oncology patients' needs among advanced practice providers (APPs). BACKGROUND:SGM individuals experience health disparities, in part due to lack of access to knowledgeable providers. Despite the important role of APPs in cancer care, less is known about their attitudes and knowledge towards SGM cancer patients. DESIGN/METHODS:Cross-sectional study. METHODS:A survey of APPs at a National Cancer Institute-Designated Comprehensive Cancer Center assessed self-reported demographics, attitudes, knowledge and postsurvey confidence in knowledge of SGM oncology patient needs. Reporting of this study adheres to STROBE guidelines. RESULTS:Knowledge of health needs was low with an average of 2.56 (SDÂ =Â 1.27) items answered correctly out of 6. The majority of APPs self-reported being comfortable treating SGM patients (93.6% and 87.2%, respectively), but less confident in knowledge of their health needs (68.0% and 53.8%, respectively). Although less than half of APPs believed education should be mandatory (44.9%), 79.5% were interested in education about SGMs' unique health needs. Political affiliation, medical specialty, licensure, and having SGM friends or family were associated with various attitude items, but not knowledge. Moderation analyses indicated that APPs who had greater overall knowledge scores were more likely to agree, on average, that knowing sexual orientation, gender identity and sex assigned at birth are important to providing quality oncology care. CONCLUSION/CONCLUSIONS:APPs report being comfortable providing care for SGMs with cancer, but knowledge gaps remain that may inhibit the quality of care provided. Given the interest in education, results would support the development of SGM-related healthcare training for oncology APPs. RELEVANCE TO CLINICAL PRACTICE/CONCLUSIONS:Targeted education for providers during training and continuing education is likely to improve the provision of quality care for SGMs with cancer.

Endocrine-disrupting chemicals: implications for human health
Since reports published in 2015 and 2016 identified 15 probable exposure-outcome associations, there has been an increase in studies in humans of exposure to endocrine-disrupting chemicals (EDCs) and a deepened understanding of their effects on human health. In this Series paper, we have reviewed subsequent additions to the literature and identified new exposure-outcome associations with substantial human evidence. Evidence is particularly strong for relations between perfluoroalkyl substances and child and adult obesity, impaired glucose tolerance, gestational diabetes, reduced birthweight, reduced semen quality, polycystic ovarian syndrome, endometriosis, and breast cancer. Evidence also exists for relations between bisphenols and adult diabetes, reduced semen quality, and polycystic ovarian syndrome; phthalates and prematurity, reduced anogenital distance in boys, childhood obesity, and impaired glucose tolerance; organophosphate pesticides and reduced semen quality; and occupational exposure to pesticides and prostate cancer. Greater evidence has accumulated than was previously identified for cognitive deficits and attention-deficit disorder in children following prenatal exposure to bisphenol A, organophosphate pesticides, and polybrominated flame retardants. Although systematic evaluation is needed of the probability and strength of these exposure-outcome relations, the growing evidence supports urgent action to reduce exposure to EDCs.

Patient-physician race/ethnicity concordance improves adherence to cardiovascular disease guidelines [Meeting Abstract]
Research Objective: Studies have found that race/ethnicity concordance between patients and providers improves medication adherence among patients with hypertension and single CVD outcomes (eg, blood pressure control). Our objective was to examine the association of patient-physician race/ethnicity concordance on adherence to the Million Hearts "ABCS" CVD guidelines: (A) aspirin when indicated, (B) blood pressure control, (C) cholesterol management, and (S) smoking screening and cessation. To the best of our knowledge, this is the first study to examine the impact of race/ ethnicity concordance on guideline adherence to multiple CVD outcome measures.
Study Design: This study was part of HealthyHearts NYC, a stepped-wedge cluster randomized controlled trial funded through AHRQ's EvidenceNOW initiative to test the effectiveness of practice facilitation on helping primary care practices adhere to CVD guidelines. The main outcomes were the Million Hearts' ABCS measures. Two additional measures were created: (a) proportion of patients who use tobacco who received a cessation intervention (smokers counseled) and (b) a composite measure that assessed the proportion of patients meeting treatment targets for A, B, and C (ABC composite). Practice-level outcome data were extracted for thirteen quarters from practices' electronic health record (EHR) systems, encompassing the control, intervention, and follow-up periods of the intervention. Patient-physician race/ethnicity concordance was calculated using patient race/ethnicity data extracted from the practices' EHR and physician race/ethnicity data collected via a Provider Survey. The concordance measure was calculated as the proportion of patients with the same race/ethnicity as the physician, for example, if practice is led by an Asian physician, and patients are 33% non-Hispanic white, 5% non-Hispanic black, 5% Hispanic, and 57% Asian, the concordance is 0.57. Population Studied: 211 small primary care practices in NYC. Principal Findings: 57.7% of Hispanic, 53.6% of black, 73.6% of Asian, 74.2% of non-Hispanic white, and 24.1% of Hawaiian/Pacific Islander patients had the same race/ethnicity as their physicians. 44.7% of physicians had the same race/ethnicity as at least 70% of their patients. Patient-physician race/ethnicity concordance was associated with adherence to four of our six outcome measures: aspirin (IRR = 1.08, 95% CI: 1.03-1.14, P < .001); blood pressure (IRR = 1.09, 95% CI: 1.07-1.12, P < .001); smoking screening and cessation (IRR = 1.06, 95% CI: 1.04-1.08, P < .001); and ABC composite (IRR = 1.42, 95% CI: 1.33-1.52, P < 0.001). We did not find an association for race/ethnicity concordance with Cholesterol and Smokers Counseled.
Conclusion(s): Increasing opportunities for patient-physician race/ ethnicity concordance may improve adherence to CVD guidelines. The largest improvement was observed in the ABC Composite measure, suggesting that patient-physician race/ethnicity concordance is particularly important for managing medically complex patients who have multiple chronic diseases. Implications for Policy or Practice: Health policy should fund programs that support the recruitment and retention of a wide diversity of students and faculty to increase the level of concordance in patient-clinician encounters. Policy makers may also want to consider legislation to help support or protect small practices that predominantly serve communities of color, where a large proportion of the physicians may be racially/ ethnically concordant with the patient population. Medical education programs should incorporate patient-physician communication training to minimize gaps potentially created by race/ethnicity discordance

Associations of spatial mobility with sexual risk behaviors among young men who have sex with men in New York City: A global positioning system (GPS) study
Spatial contexts and spatial mobility are important factors of the HIV epidemic and sexually transmitted infections. Using global positioning system (GPS) devices, we examined the associations of objectively measured spatial mobility with sexual risk behaviors among gay, bisexual and other men who have sex with men (MSM) in New York City. This observational study included a subgroup of 253 HIV-negative MSM from the Project 18 Cohort Study, who participated in the GPS monitoring sub-study. Spatial mobility was measured as (1) distance traveled and (2) activity space size defined as daily path area during 2-week of GPS tracking. We examined the associations of these measures with numbers of male sexual partners and condomless anal intercourse (CAI) acts during last six months using quasi-Poisson models, adjusting for socio-demographics. Results demonstrated that spatial mobility was positively associated with sexual risk behaviors, for example, with CAI (incidence rate ratio [IRR]Â =Â 1.01 for a 10Â km increase in distance traveled and IRRÂ =Â 1.04 for a 1Â km2 increase in 50Â m-buffer activity space size). Our findings may enhance the understanding of spatial contexts of HIV risk. Future studies should be conducted to examine the mechanisms for the associations between spatial mobility behaviors with sexual risk behaviors as well as the influence of neighborhood characteristics in various neighborhood contexts, which may guide the place-based HIV prevention services.

Disease severity and quality of life in homebound people with advanced Parkinson disease: A pilot study
Background/UNASSIGNED:care could improve our understanding of disease progression, treatment options, and unmet needs in this vulnerable population, and whether such a model could mitigate decline in QoL. Methods/UNASSIGNED:Patients with PD meeting Medicare homebound criteria were eligible for quarterly interdisciplinary home visits over 12 months. Each visit entailed an evaluation by a movement disorders neurologist, social worker, and nurse, including history, examination, medication reconciliation, psychosocial evaluation, pharmacologic and nonpharmacologic management, and service referrals. Disease severity, as measured by the Unified Parkinson's Disease Rating Scale (UPDRS), and QoL using the Neuro-QoL were measured at visits 1 and 4. Results/UNASSIGNED:= 0.19-0.95). Conclusions/UNASSIGNED:Homebound individuals with advanced PD receiving interdisciplinary home visits experienced no significant decline in QoL over 1 year, despite disease progression. Our findings highlight the disease severity and impaired QoL of the advanced, homebound PD population, and the potential for novel approaches to foster continuity of care.

Cardiovascular disease and asymptomatic childhood cancer survivors: Current clinical practice
BACKGROUND:It is poorly understood how cardiovascular screening in asymptomatic childhood cancer survivors (CCS) is applied to and impacts clinical care. OBJECTIVES:To describe the current role of cardiovascular screening in the clinical care of asymptomatic CCS. METHODS:At 50 pediatric academic medical centers, a childhood cancer survivorship clinic director, pediatric cardiologist, and adult cardiologist with a focus on CCS were identified and invited to participate in a survey. Surveys were managed electronically. Categorical data were analyzed using nonparametric methods. RESULTS:Of the 95 (63%) respondents, 39% were survivorship practitioners, and 61% were cardiologists. Eighty-eight percent of survivorship practitioners reported that greater than half of CCS received cardiovascular screening. CCS followed by adult cardiology were more likely to be seen by a cardio-oncologist. Those followed by pediatric cardiology were more likely to be seen by a heart failure/transplant specialist. Common reasons for referral to cardiology were abnormal cardiovascular imaging or concerns a CCS was at high risk for cardiovascular disease. Ninety-two percent of cardiologists initiated angiotensin converting enzyme inhibitor or angiotensin receptor blocker therapy for mild systolic dysfunction. Adult cardiologists initiated beta-blocker therapy for less severe systolic dysfunction compared to pediatric cardiologists (PÂ <Â .001). Pediatric cardiologists initiated mineralocorticoid therapy for less severe systolic dysfunction compared to adult cardiologists (PÂ =Â .025). Practitioners (93%) support a multi-institutional collaboration to standardize cardiovascular care for CCS. CONCLUSIONS:While there is much common ground in the clinical approach to CCS, heterogeneity is evident. This highlights the need for cohesive, multi-institutional, standardized approaches to cardiovascular management in CCS.

STudy of Alteplase for Respiratory failure in SARS-Cov2/COVID-19: Study Design of the Phase IIa STARS Trial
Background/UNASSIGNED:The COVID-19 pandemic has caused a large surge of acute respiratory distress syndrome (ARDS). Prior phase I trials (non COVID-19) demonstrated improvement in pulmonary function in ARDS patients using fibrinolytic therapy. A follow-up trial using the widely available tissue-plasminogen activator (alteplase) is now needed to assess optimal dosing and safety in this critically ill patient population. Objective/UNASSIGNED:To describe the design and rationale of a Phase IIa trial to evaluate the safety and efficacy of alteplase treatment for moderate/severe COVID-19-induced ARDS. Patients/Methods/UNASSIGNED:A rapidly adaptive, pragmatic, open label, randomized, controlled, phase IIa clinical trial will be conducted with three groups: intravenous(IV) alteplase 50mg, IV alteplase 100mg, and control (standard-of-care). Inclusion criteria are known/suspected COVID-19 infection with PaO2/FiO2 ratio<150mmHg for >4 hours despite maximal mechanical ventilation management. Alteplase will be delivered through an initial bolus of 50mg or 100mg followed by heparin infusion for systemic anticoagulation, with alteplase re-dosing if there is a >20% PaO2/FiO2 improvement not sustained by 24 hours. Results/UNASSIGNED:The primary outcome is improvement in PaO2/FiO2 at 48 hours post-randomization. Other outcomes include: ventilator- and ICU-free-days, successful extubation (no reintubation ≤3 days after initial extubation), and mortality. Fifity eligible patients will be enrolled in a rapidly adaptive, modified stepped-wedge design with four looks at the data. Conclusion/UNASSIGNED:Findings will provide timely information on the safety, efficacy and optimal dosing of tPA to treat moderate/severe COVID-19-induced ARDS, which can be rapidly adapted to a phase III trial.

Mapping geographical inequalities in oral rehydration therapy coverage in low-income and middle-income countries, 2000-17
BACKGROUND:Oral rehydration solution (ORS) is a form of oral rehydration therapy (ORT) for diarrhoea that has the potential to drastically reduce child mortality; yet, according to UNICEF estimates, less than half of children younger than 5 years with diarrhoea in low-income and middle-income countries (LMICs) received ORS in 2016. A variety of recommended home fluids (RHF) exist as alternative forms of ORT; however, it is unclear whether RHF prevent child mortality. Previous studies have shown considerable variation between countries in ORS and RHF use, but subnational variation is unknown. This study aims to produce high-resolution geospatial estimates of relative and absolute coverage of ORS, RHF, and ORT (use of either ORS or RHF) in LMICs. METHODS:We used a Bayesian geostatistical model including 15 spatial covariates and data from 385 household surveys across 94 LMICs to estimate annual proportions of children younger than 5 years of age with diarrhoea who received ORS or RHF (or both) on continuous continent-wide surfaces in 2000-17, and aggregated results to policy-relevant administrative units. Additionally, we analysed geographical inequality in coverage across administrative units and estimated the number of diarrhoeal deaths averted by increased coverage over the study period. Uncertainty in the mean coverage estimates was calculated by taking 250 draws from the posterior joint distribution of the model and creating uncertainty intervals (UIs) with the 2·5th and 97·5th percentiles of those 250 draws. FINDINGS:While ORS use among children with diarrhoea increased in some countries from 2000 to 2017, coverage remained below 50% in the majority (62·6%; 12 417 of 19 823) of second administrative-level units and an estimated 6 519 000 children (95% UI 5 254 000-7 733 000) with diarrhoea were not treated with any form of ORT in 2017. Increases in ORS use corresponded with declines in RHF in many locations, resulting in relatively constant overall ORT coverage from 2000 to 2017. Although ORS was uniformly distributed subnationally in some countries, within-country geographical inequalities persisted in others; 11 countries had at least a 50% difference in one of their units compared with the country mean. Increases in ORS use over time were correlated with declines in RHF use and in diarrhoeal mortality in many locations, and an estimated 52 230 diarrhoeal deaths (36 910-68 860) were averted by scaling up of ORS coverage between 2000 and 2017. Finally, we identified key subnational areas in Colombia, Nigeria, and Sudan as examples of where diarrhoeal mortality remains higher than average, while ORS coverage remains lower than average. INTERPRETATION:To our knowledge, this study is the first to produce and map subnational estimates of ORS, RHF, and ORT coverage and attributable child diarrhoeal deaths across LMICs from 2000 to 2017, allowing for tracking progress over time. Our novel results, combined with detailed subnational estimates of diarrhoeal morbidity and mortality, can support subnational needs assessments aimed at furthering policy makers' understanding of within-country disparities. Over 50 years after the discovery that led to this simple, cheap, and life-saving therapy, large gains in reducing mortality could still be made by reducing geographical inequalities in ORS coverage.

CKD in China: Evolving Spectrum and Public Health Implications
Diabetes is the leading cause of kidney failure worldwide, whereas glomerulonephritis has been predominant in developing countries such as China. The prevalence of obesity and diabetes has increased dramatically in developing countries, substantially affecting the patterns of chronic kidney disease (CKD) observed in these regions. Using data from the Hospital Quality Monitoring System to evaluate changes in the spectrum of non-dialysis-dependent CKD in China, we have observed an increase in the percentage of patients with CKD due to diabetes, which has exceeded that of CKD due to glomerulonephritis since 2011, as well as an increase in hypertensive nephropathy and, in some regions, obstructive kidney disease (mostly associated with kidney stones). The growth of noncommunicable diseases under profound societal and environmental changes has shifted the spectrum of CKD in China toward patterns similar to those of developed countries, which will have enormous impacts on the Chinese health care system. There is much to be done regarding public health interventions, including the establishment of a national CKD surveillance system, improvement in the management of diabetes and hypertension, and enhancement of the affordability and accessibility of kidney replacement therapy. Reducing the burden of CKD will require joint efforts from government, the medical community (including practitioners other than nephrologists), and the public.

Concordance and Discordance in the Geographic Distribution of Childhood Obesity and Pediatric Type 2 Diabetes in New York City
OBJECTIVE:s rates of childhood obesity and pediatric type 2 diabetes (T2D) increase, a better understanding is needed of how these two conditions relate, and which subgroups of children are more likely to develop diabetes with and without obesity. METHODS:To compare hotspots of childhood obesity and pediatric T2D in New York City, we performed geospatial clustering analyses on obesity estimates obtained from surveys of school-aged children and diabetes estimates obtained from healthcare claims data, from 2009-2013. Analyses were performed at the Census tract level. We then used multivariable regression analysis to identify sociodemographic and environmental factors associated with these hotspots. RESULTS:We identified obesity hotspots in Census tracts with a higher proportion of Black or Hispanic residents, with low median household income, or located in a food swamp. 51.1% of pediatric T2D hotspots overlapped with obesity hotspots. For pediatric T2D, hotspots were identified in Census tracts with a higher proportion of Black residents and a lower proportion of Hispanic residents. CONCLUSIONS:Non-Hispanic Black neighborhoods had a higher probability of being hotspots of both childhood obesity and pediatric type 2 diabetes. However, we identified a discordance between hotspots of childhood obesity and pediatric diabetes in Hispanic neighborhoods, suggesting either under-detection or under-diagnosis of diabetes, or that obesity may influence diabetes risk differently in these two populations. These findings warrant further investigation of the relationship between childhood obesity and pediatric diabetes among different racial and ethnic groups, and may help guide pediatric public health interventions to specific neighborhoods.
