Abstract
OBJECTIVES Vicarious racism-witnessing or hearing about other individuals of one's ethnic/racial group being the target of racism-has been salient among Asian Americans during the coronavirus disease (COVID-19) pandemic. There is emerging evidence that such experiences adversely impact several health-related outcomes, including sleep. The present study examines associations between vicarious racism and subjective sleep duration and quality, and the potential moderating role of ethnic/racial identity (ERI). METHOD Multivariable regression models assessed the association between vicarious racism, private regard, and centrality on self-reported sleep disturbance and duration. The sample consisted of an online sample of 600 Asian American adults (Mage = 38.55, SDage = 17.11; 65.17% female; 60% ≥ Bachelor's degree) recruited from May to June 2020. RESULTS Vicarious racism was associated with compromised sleep quality and duration, including after adjustment for sociodemographic variables that have been linked to sleep. Private regard toward one's own ethnic/racial group and centrality of ethnicity/race to self-identity buffered the association between vicarious racism and sleep quality and duration. Adverse effects of high vicarious racism on sleep quality and duration were lessened among respondents reporting high levels of ERI private regard and centrality. CONCLUSIONS Findings from this study extend research on racism and sleep by examining vicarious racism, an understudied facet of racism, and by focusing specifically on Asian Americans and in the context of the COVID-19 pandemic. Future research and practice should consider expanding research on discrimination to include a broader range of unjust experiences. Vicarious racism contributes to health hazards experienced by Asian Americans during the COVID-19 pandemic. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Introduction: The shift from in-person care to telemedicine made it challenging
to provide guideline-recommended tobacco cessation care during
the COVID-19 pandemic. We described quality improvement (QI)
initiatives for tobacco cessation during the COVID-19 pandemic,
focusing on African American/Black patients with high smoking
rates. Methods: The QI initiatives took place in the San Francisco Health Network,
a network of 13 safety-net clinics in San Francisco, California
between February 2020 and February 2022. We conducted direct
patient outreach by telephone and increased staff capacity to
increase cessation care delivery. We examined trends in tobacco
screening, provider counseling, and best practice for cessation
care (ie, the proportion of patients receiving at least 1
smoking cessation service during a clinical encounter). Results: In-person visits at the onset of the pandemic was 20% in April 2020
and increased to 67% by February 2022. During this time, tobacco
screening increased from 29% to 74%. From March 2020 to March
2021, 34% more patients received provider counseling by
telephone than in-person. The trend reversed from April 2021 to
February 2022, where 23% more patients received counseling
in-person than by telehealth. Best practice care increased by
23% from June 2020 to February 2022: 24% for African
American/Black patients and 23% for other patients. Conclusions: Telehealth adaptations to the EHR, targeted outreach to patients,
and a multi-disciplinary medical team may be associated with
increases in cessation care delivery during the COVID-19
pandemic.

Abstract
Black Americans have experienced multiple health threats during the COVID-19 pandemic, including greater risk of infection compared to Whites. In addition, older adults are more susceptible to worse disease consequences including hospitalization and mortality compared to those who are younger. Racism and economic costs are additional public health crises during this time that have disproportionately impacted Black Americans. Using data from the Uncovering COVID-19 Experiences and Realities (UnCOVER) Study, we examined depressive symptoms in relation to: (1) worry/fear of COVID-19; (2) work loss among household members (being laid off, reduced work hours); and (3) vicarious racism, a particularly salient source of psychosocial stress during the COVID-19 pandemic, including hearing about or seeing acts of racism committed against other race group members. Participants were Black Americans aged 50 years or older (n=300) from five cities (Atlanta, Chicago, Los Angeles, New Orleans, and New York) from May-July 2020. Depression was assessed using the Patient-Reported Outcomes Measurement Information System Short Form. In multivariable linear regression models, all three public health threats were significantly associated with depressive symptoms. When in the model simultaneously, worry/fear of COVID-19 (b=0.30, SE=0.12, p<0.01) and vicarious racism (b=0.62, SE=0.15, p<0.001) showed positive associations; work loss was no longer statistically significant (b=0.62, SE=0.43, p=0.15). When added, the corresponding three-way interaction term was significant (b=0.12, SE=0.04, p<0.01). Synergistic epidemics (“syndemics”) among older Black Americans amplify mental health tolls. Multi-pronged public health strategies are required to address depression in this population.

Abstract
Both society and psychological science are deeply grounded in (and often perpetuate) white supremacy and anti-Blackness. While human development is inextricable from macro-level structural racism and hierarchies of oppression, developmental research often locates processes in the micro-level of individuals and relationships, ultimately obscuring how intimately macro-level forces shape developmental processes. The current paper aims to shift the starting point of the story of human development by centering the macrosystem, and specifically racism (and its partnering ideologies of sexism, heteronormativity, classism, and capitalism) in ecological systems theory and developmental psychology broadly. Through the lens of racial socialization research, we present an empirical example to illustrate how the sociopolitical context of racism is itself a source of socialization. Finally, we propose new language, <i>m(ai)cro</i>, to conceptualize the simultaneous and transactional macro-as-micro processes in development. We conclude with guiding principles for how to work toward equity and justice in human development.

Abstract
Depression is a common comorbidity among Black women with systemic lupus erythematosus (SLE), an understudied autoimmune disease characterized by major racial and gender inequities. Research is needed that examines how area-level factors influence risk of depression in this population. Latent profile analysis revealed four neighborhood typologies among metropolitan Atlanta, Georgia census tracts that participants (n=438) in the Black Women's Experiences Living with Lupus (BeWELL) Study were living in: Integrated/High-SES, Moderately Segregated/Mid-SES, Highly Segregated/Mid-SES, and Highly Segregated/Low-SES. Structural equation models indicated that highly segregated census tracts were associated with the greatest levels of depression via increased subjective assessments of neighborhood disorder. Policies that invest in segregated areas and address physical and social aspects of the environment that contribute to neighborhood disorder may promote mental health among Black women with SLE.

Abstract
OBJECTIVES Experiences of vicarious racism-hearing about racism directed toward one's racial group or racist acts committed against other racial group members-and vigilance about racial discrimination have been salient during the COVID-19 pandemic. This study examined vicarious racism and vigilance in relation to symptoms of depression and anxiety among Asian and Black Americans. METHODS We used data from a cross-sectional study of 604 Asian American and 844 Black American adults aged ≥18 in the United States recruited from 5 US cities from May 21 through July 15, 2020. Multivariable linear regression models examined levels of depression and anxiety by self-reported vicarious racism and vigilance. RESULTS Controlling for sociodemographic characteristics, among both Asian and Black Americans, greater self-reported vicarious racism was associated with more symptoms of depression (Asian: β = 1.92 [95% CI, 0.97-2.87]; Black: β = 1.72 [95% CI, 0.95-2.49]) and anxiety (Asian: β = 2.40 [95% CI, 1.48-3.32]; Black: β = 1.98 [95% CI, 1.17-2.78]). Vigilance was also positively related to symptoms of depression (Asian: β = 1.54 [95% CI, 0.58-2.50]; Black: β = 0.90 [95% CI, 0.12-1.67]) and anxiety (Asian: β = 1.98 [95% CI, 1.05-2.91]; Black: β = 1.64 [95% CI, 0.82-2.45]). CONCLUSIONS Mental health problems are a pressing concern during the COVID-19 pandemic. Results from our study suggest that heightened racist sentiment, harassment, and violence against Asian and Black Americans contribute to increased risk of depression and anxiety via vicarious racism and vigilance. Public health efforts during this period should address endemic racism as well as COVID-19.

Abstract
Introduction Incidence for depression increases during the perinatal period. Risk factors for depression may differentially affect each time period. Objectives To assess demographic, psychological and obstetric risk factors that differentially affect prenatal and postpartum depression Methods A total of 169 subjects participated. Assessment was conducted during the first trimester, second trimester, third trimester, within a month after childbirth, and a month after childbirth. Demographic and obstetric measures, as well as psychological measures, including the Edinburgh Postnatal Depression Scale were conducted. Multiple regression and the Mann-Whitney U test were performed to examine the association between variables and depression scores. Results Depression score was higher during the postpartum period than the prenatal period. Younger age was associated with depression during the first trimester. In the second trimester, less education, a history of depression and having stress within a year significantly affected depression scores. Smoking, artificial abortion and lack of support from family and parents correlated with depression during the third trimester. Within a month after childbirth, psychiatric and depression history, smoking, stress level within a year and lack of family support were associated with depression. At a month after childbirth, those who were primiparous and not breastfeeding had significantly higher depression scores. Conclusions This study identifies various risk factors for each gestational and postpartum period and suggests differential interventions for different perinatal periods.

Abstract
Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease marked by inflammation that disproportionately impacts Black women. Telomeres are repetitive sequences of DNA capping the ends of chromosomes that shorten more rapidly in response to inflammation. Studies suggest that the telomere maintenance system may be disrupted in those with SLE, who have been shown to have shorter telomeres compared to healthy controls. Among those with SLE, Blacks have been found to experience more accelerated telomere shortening compared to those of other race groups. We examined the relationship between telomere length (TL) and mortality using data from the Black Women’s Experiences Living with Lupus (BeWELL) Study. Participants were 438 Black women with a validated diagnosis of SLE living in the Atlanta, Georgia metropolitan area, recruited between April 2015 and May 2017 predominantly from a large population-based registry. TL was assayed from dried blood spots collected at baseline and measured as the relative telomere to single copy gene (T/S) ratio. Mortality was assessed prospectively through April 2019. A total of 24 participants died during this time period. There was a negative association between TL and mortality, with shorter TL being associated with greater mortality risk (hazard ratio = 0.01, p=0.02). This relationship remained statistically significant after controlling for age and years since diagnosis, and further adjustment for a range of socio-demographic and health-related factors, including SLE damage and activity. Findings suggest that TL may forecast mortality among Black women with SLE. The association between TL and mortality among people with SLE should be further explored.

Abstract
Disparate health consequences in African American women with systemic lupus erythematosus include greater severity of physical and psychological distress. Racism-related stress is also related to psychological distress correlates in this population. This study examined the relationships between racism-related experiences, psychological distress, and systemic lupus erythematosus activity in 430 African American women from the Black Women's Experiences Living with Lupus study. The structural equation model suggests that psychological distress mediates the relationship between racism-related stress and systemic lupus erythematosus disease activity. The impact of racism-related stress on systemic lupus erythematosus disease activity may occur primarily through their impact on psychological health variables. Implications for clinical care and future directions are explored.

Abstract
Purpose To compare ovulation rates between Letrozole and Clomiphene Citrate (CC) using a stair-step protocol to achieve ovulation induction in women with Polycystic Ovarian Syndrome (PCOS). Methods This is a retrospective cohort of predominantly Hispanic PCOS women of reproductive age who completed ovulation induction (OI) comparing women who underwent Letrozole stair-step protocol to those who underwent OI with CC stair-step. All women had a diagnosis of PCOS based on the 2003 Rotterdam criteria. For both protocols, sequentially higher doses of Letrozole or CC were given 7 days after the last dose if no dominant follicles were seen on ultrasonography. The primary outcome was ovulation rate (determined by presence of a dominant follicle) between the two treatment groups. Secondary outcomes included time to ovulation, clinical pregnancy rates and side effects. Results 49 PCOS patients completed a Letrozole stair-step cycle and 43 completed a CC stair-step cycle for OI. Overall, demographics were comparable between both groups. Ovulation rates with the Letrozole stair-step protocol were equivalent to CC stair-step protocol (96% vs 88%, p = 0.17). Although the mean time (days) to ovulation was shorter in the Letrozole group (19.5 vs 23.1, p = 0.027), the pregnancy rates were similar for both groups. Conclusions This is the first study to date that has compared the efficacy of the stair-step protocol in PCOS patients using Letrozole and CC. Both Letrozole and CC can be prescribed in a stair-step fashion. Letrozole stair-step was as efficacious as CC stair-step; patients achieved comparable rates of ovulation and clinical pregnancy. Time to ovulation was shorter in the Letrozole protocol.

Abstract
BACKGROUND Indirect or vicarious exposure to racism (e.g., hearing about or observing acts of racism or discrimination) is a salient source of stress for African Americans. Emerging research suggests that these "secondhand" experiences of racism may contribute to racial health inequities through stress-mediated pathways. Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease that disproportionately impacts African American women and is characterized by racial disparities in severity. Health outcomes in this population may be susceptible to vicarious racism given that SLE is shown to be sensitive to psychosocial stress. METHODS Data are from 431 African American women with SLE living in Atlanta, Georgia in the Black Women's Experiences Living with Lupus (BeWELL) Study (2015-2017). Vicarious racism stress was measured with four items assessing distress from (1) hearing about racism in the news; (2) experiences of racism among friends or family; (3) witnessing racism in public; and (4) racism depicted in movies and television shows. Multivariable linear regression was used to examine associations with disease activity measured using the Systemic Lupus Activity Questionnaire. RESULTS Adjusting for sociodemographic and health-related covariates, vicarious racism stress was associated with greater disease activity (b = 2.15; 95% CI = 1.04-3.27). This association persisted even after adjustment for personal experiences of racial discrimination (b = 1.80; 95% CI = 0.67-2.92). CONCLUSIONS Vicarious racism may result in heightened disease activity and contribute to racial disparities in SLE. Our findings suggest that acts of racism committed against members of one's racial group may have distinct health consequences beyond the immediate victim or target.

Abstract
BACKGROUND AND PURPOSE Thrombus characteristics identified on non-contrast CT (NCCT) are potentially associated with recanalization with intravenous (IV) alteplase in patients with acute ischemic stroke (AIS). Our aim was to determine the best radiomics-based features of thrombus on NCCT and CT angiography associated with recanalization with IV alteplase in AIS patients and proximal intracranial thrombi. MATERIALS AND METHODS With a nested case-control design, 67 patients with ICA/M1 MCA segment thrombus treated with IV alteplase were included in this analysis. Three hundred twenty-six radiomics features were extracted from each thrombus on both NCCT and CTA images. Linear discriminative analysis was applied to select features most strongly associated with early recanalization with IV alteplase. These features were then used to train a linear support vector machine classifier. Ten times 5-fold cross-validation was used to evaluate the accuracy of the trained classifier and the stability of the selected features. RESULTS Receiver operating characteristic curves showed that thrombus radiomics features are predictive of early recanalization with IV alteplase. The combination of radiomics features from NCCT, CTA, and radiomics changes is best associated with early recanalization with IV alteplase (area under the curve = 0.85) and was significantly better than any single feature such as thrombus length (P < .001), volume (P < .001), and permeability as measured by mean attenuation increase (P < .001), maximum attenuation in CTA (P < .001), maximum attenuation increase (P < .001), and assessment of residual flow grade (P < .001). CONCLUSIONS Thrombus radiomics features derived from NCCT and CTA are more predictive of recanalization with IV alteplase in patients with acute ischemic stroke with proximal occlusion than previously known thrombus imaging features such as length, volume, and permeability.

Abstract
Pearl dace (Semotilus margarita) and brook stickleback (Culaea inconstans) were collected from tributaries of the Athabasca River (Alberta, Canada), upstream (reference site) and downstream of oil sands deposits where fish were expected to be exposed to naturally occurring oil sands constituents. The objective was to determine if fish collected from these sites exhibited differences in the prevalence or intensity of infection by parasites or in gill histology. Dace did not display significant differences in these parameters. Alternately, upstream stickleback were predominantly infected by complex life history parasites, while downstream fish were primarily infected by parasites with simpler life histories. Moreover, downstream stickleback exhibited significantly more clubbing and aneurysms in secondary gill lamellae relative to upstream fish. This suggested a difference in habitat quality between upstream and downstream sites. However, based on basic body condition parameters of the fish, it would appear that any impacts upon the health of the fish due to the presence of naturally occurring oil sands associated chemical constituents would have been minor.
