Reliever-Triggered Inhaled Glucocorticoid in Black and Latinx Adults with Asthma.

BACKGROUND: Black and Latinx patients bear a disproportionate burden of asthma. Efforts to reduce the disproportionate morbidity have been mostly unsuccessful, and guideline recommendations have not been based on studies in these populations. METHODS: In this pragmatic, open-label trial, we randomly assigned Black and Latinx adults with moderate-to-severe asthma to use a patient-activated, reliever-triggered inhaled glucocorticoid strategy (beclomethasone dipropionate, 80 µg) plus usual care (intervention) or to continue usual care. Participants had one instructional visit followed by 15 monthly questionnaires. The primary end point was the annualized rate of severe asthma exacerbations. Secondary end points included monthly asthma control as measured with the Asthma Control Test (ACT; range, 5 [poor] to 25 [complete control]), quality of life as measured with the Asthma Symptom Utility Index (ASUI; range, 0 to 1, with lower scores indicating greater impairment), and participant-reported missed days of work, school, or usual activities. Safety was also assessed. RESULTS: Of 1201 adults (603 Black and 598 Latinx), 600 were assigned to the intervention group and 601 to the usual-care group. The annualized rate of severe asthma exacerbations was 0.69 (95% confidence interval [CI], 0.61 to 0.78) in the intervention group and 0.82 (95% CI, 0.73 to 0.92) in the usual-care group (hazard ratio, 0.85; 95% CI, 0.72 to 0.999; P = 0.048). ACT scores increased by 3.4 points (95% CI, 3.1 to 3.6) in the intervention group and by 2.5 points (95% CI, 2.3 to 2.8) in the usual-care group (difference, 0.9; 95% CI, 0.5 to 1.2); ASUI scores increased by 0.12 points (95% CI, 0.11 to 0.13) and 0.08 points (95% CI, 0.07 to 0.09), respectively (difference, 0.04; 95% CI, 0.02 to 0.05). The annualized rate of missed days was 13.4 in the intervention group and 16.8 in the usual-care group (rate ratio, 0.80; 95% CI, 0.67 to 0.95). Serious adverse events occurred in 12.2% of the participants, with an even distribution between the groups. CONCLUSIONS: Among Black and Latinx adults with moderate-to-severe asthma, provision of an inhaled glucocorticoid and one-time instruction on its use, added to usual care, led to a lower rate of severe asthma exacerbations.

Asthma morbidity measures across Black ethnic subgroups.

BACKGROUND: Black adults are disproportionately affected by asthma and are often considered a homogeneous group in research studies despite cultural and ancestral differences. OBJECTIVE: We sought to determine if asthma morbidity differs across adults in Black ethnic subgroups. METHODS: Adults with moderate-severe asthma were recruited across the continental United States and Puerto Rico for the PREPARE (PeRson EmPowered Asthma RElief) trial. Using self-identifications, we categorized multiethnic Black (ME/B) participants (n = 226) as Black Latinx participants (n = 146) or Caribbean, continental African, or other Black participants (n = 80). African American (AA/B) participants (n = 518) were categorized as Black participants who identified their ethnicity as being American. Baseline characteristics and retrospective asthma morbidity measures (self-reported exacerbations requiring systemic corticosteroids [SCs], emergency department/urgent care [ED/UC] visits, hospitalizations) were compared across subgroups using multivariable regression. RESULTS: Compared with AA/B participants, ME/B participants were more likely to be younger, residing in the US Northeast, and Spanish speaking and to have lower body mass index, health literacy, and <1 comorbidity, but higher blood eosinophil counts. In a multivariable analysis, ME/B participants were significantly more likely to have ED/UC visits (incidence rate ratio [IRR] = 1.34, 95% CI = 1.04-1.72) and SC use (IRR = 1.27, 95% CI = 1.00-1.62) for asthma than AA/B participants. Of the ME/B subgroups, Puerto Rican Black Latinx participants (n = 120) were significantly more likely to have ED/UC visits (IRR = 1.64, 95% CI = 1.22-2.21) and SC use for asthma (IRR = 1.43, 95% CI = 1.06-1.92) than AA/B participants. There were no significant differences in hospitalizations for asthma among subgroups. CONCLUSIONS: ME/B adults, specifically Puerto Rican Black Latinx adults, have higher risk of ED/UC visits and SC use for asthma than other Black subgroups.

Longitudinal quality of life after sublobar resection and stereotactic body radiation therapy for early-stage non-small cell lung cancer.

BACKGROUND: Many patients with early-stage lung cancer are not candidates for lobectomy because of various factors, with treatment options including sublobar resection or stereotactic body radiation therapy (SBRT). Limited information exists regarding patient-centered outcomes after these treatments. METHODS: Subjects with stage I-IIA non-small cell lung cancer (NSCLC) at high risk for lobectomy who underwent treatment with sublobar resection or SBRT were recruited from five medical centers. Quality of life (QOL) was compared with the Short Form 8 (SF-8) for physical and mental health and Functional Assessment of Cancer Therapy-Lung (FACT-L) surveys at baseline (pretreatment) and 7 days, 30 days, 6 months, and 12 months after treatment. Propensity score methods were used to control for confounders. RESULTS: Of 337 subjects enrolled before treatment, 63% received SBRT. Among patients undergoing resection, 89% underwent minimally invasive video-assisted thoracic surgery or robot-assisted resection. Adjusted analyses showed that SBRT-treated patients had both higher physical health SF-8 scores (difference in differences [DID], 6.42; p = .0008) and FACT-L scores (DID, 2.47; p = .004) at 7 days posttreatment. Mental health SF-8 scores were not different at 7 days (p = .06). There were no significant differences in QOL at other time points, and all QOL scores returned to baseline by 12 months for both groups. CONCLUSIONS: SBRT is associated with better QOL immediately posttreatment compared with sublobar resection. However, both treatment groups reported similar QOL at later time points, with a return to baseline QOL. These findings suggest that sublobar resection and SBRT have a similar impact on the QOL of patients with early-stage lung cancer deemed ineligible for lobectomy.

Examining the Trajectory of Health-Related Quality of Life among Coronavirus Disease Patients.

BACKGROUND: Recent studies have reported a reduction in health-related quality of life (HR-QoL) among post-coronavirus disease 2019 (COVID-19) patients. However, there remains a gap in research examining the heterogeneity and determinants of HR-QoL trajectory in these patients. OBJECTIVE: To describe and identify factors explaining the variability in HR-QoL trajectories among a cohort of patients with history of COVID-19. DESIGN: A prospective study using data from a cohort of COVID-19 patients enrolled into a registry established at a health system in New York City. PARTICIPANTS: Participants were enrolled from July 2020 to June 2022, and completed a baseline evaluation and two follow-up visits at 6 and 12 months. METHODS: We assessed HR-QoL with the 29-item Patient Reported Outcomes Measurement Information System instrument, which was summarized into mental and physical health domains. We performed latent class growth and multinomial logistic regression to examine trajectories of HR-QoL and identify factors associated with specific trajectories. RESULTS: The study included 588 individuals with a median age of 52 years, 65% female, 54% White, 18% Black, and 18% Hispanic. We identified five physical health trajectories and four mental health trajectories. Female gender, having pre-existing hypertension, cardiovascular disease, asthma, and hospitalization for acute COVID-19 were independently associated with lower physical health. In addition, patients with increasing body mass index were more likely to experience lower physical health over time. Female gender, younger age, pre-existing asthma, arthritis and cardiovascular disease were associated with poor mental health. CONCLUSIONS: We found significant heterogeneity of HR-QoL after COVID-19, with women and patients with specific comorbidities at increased risk of lower HR-QoL. Implementation of targeted psychological and physical interventions is crucial for enhancing the quality of life of this patient population.

Challenges Addressing Lung Cancer Screening for Patients With Multimorbidity in Primary Care: A Qualitative Study.

PURPOSE: Many individuals who are eligible for lung cancer screening have comorbid conditions complicating their shared decision-making conversations with physicians. The goal of our study was to better understand how primary care physicians (PCPs) factor comorbidities into their evaluation of the risks and benefits of lung cancer screening and into their shared decision-making conversations with patients. METHODS: We conducted semistructured interviews by videoconference with 15 PCPs to assess the extent of shared decision-making practices and explore their understanding of the intersection of comorbidities and lung cancer screening, and how that understanding informed their clinical approach to this population. RESULTS: We identified 3 themes. The first theme was whether to discuss or not to discuss lung cancer screening. PCPs described taking additional steps for individuals with complex comorbidities to decide whether to initiate this discussion and used subjective clinical judgment to decide whether the conversation would be productive and beneficial. PCPs made mental assessments that factored in the patient's health, life expectancy, quality of life, and access to support systems. The second theme was that shared decision making is not a simple discussion. When PCPs did initiate discussions about lung cancer screening, although some believed they could provide objective information, others struggled with personal biases. The third theme was that ultimately, the decision to be screened was up to the patient. Patients had the final say, even if their decision was discordant with the PCP's advice. CONCLUSIONS: Shared decision-making conversations about lung cancer screening differed substantially from the standard for patients with complex comorbidities. Future research should include efforts to characterize the risks and benefits of LCS in patients with comorbidities to inform guidelines and clinical application.

World Trade Center workers with asthma and post-traumatic stress disorder perceive airflow limitation more accurately.

BACKGROUND: Post-traumatic stress disorder (PTSD) is a major risk factor for increased asthma morbidity among World Trade Center (WTC) workers. OBJECTIVE: To investigate whether differences in perception of airflow limitation mediate the association of PTSD with worse asthma control in WTC workers. METHODS: We collected data from WTC workers on asthma control (Asthma Control Questionnaire and Asthma Quality of Life Questionnaire) and daily peak expiratory flow (PEF) measures over 6 weeks. Perception of airway limitation was assessed by comparing guessed vs actual PEF values. Post-traumatic stress disorder was diagnosed using the Structured Clinical Interview. We used unadjusted and adjusted models to compare PEF and perception measures in WTC workers with PTSD with those of workers without PTSD. RESULTS: Overall, 25% of 224 participants had PTSD. Post-traumatic stress disorder was associated with worse Asthma Control Questionnaire (2.2±0.8 vs 1.1±0.9, P < .001) and Asthma Quality of Life Questionnaire (3.9±1.1 vs 5.4±1.1, P < .001) scores. Adjusted analyses showed no significant differences in PEF between WTC workers with (351.9±143.3 L/min) and those without PTSD (364.6±131.6 L/min, P = .55). World Trade Center workers with PTSD vs those without PTSD had increased proportion of accurate perception (67.0±37.2% vs 53.5±38.1%, P = .01) and decreased underperception (23.3.0±32.1% vs 38.9±37.5%, P = .004) of airflow limitation during periods of limitation. Similar results were obtained in adjusted analyses. CONCLUSION: This study indicates that differences in perception of airflow limitation may mediate the relationship of PTSD and increased asthma symptoms, given WTC workers with PTSD have worse self-reported asthma control, an increased proportion of accurate perception, and decreased underperception, despite no differences in daily PEF measures.

The relationships between Physical activity and asthma control and Body Mass Index (BMI) in patients with asthma.

OBJECTIVE: Asthma is one of the most common chronic conditions in developed countries. We examined whether physical activity (PA) is related to asthma control and body mass index (BMI) in asthma patients. METHODS: Cross-sectional data collected on PA (ActiGraph GT3X-BT), asthma control (the Asthma Control Questionnaire; ACQ), and BMI were examined in 206 adults (mean[sd] age 47.2[13.8] years; 49.5% had an obese BMI) with clinically diagnosed asthma. Relationships between PA and continuous BMI and asthma control were assessed using linear regression. Differences in PA across obesity (non-obese: <30 Kg/m2/obese: ≥30 Kg/m2) and asthma control categories (controlled: ≤0.75/uncontrolled: >0.75 ACQ score) were also examined. RESULTS: Median (p25, p75) steps counts and peak cadence were 6035 (4248, 8461) steps/day and 123 (115, 133) steps in a minute, respectively. There were nearly 2000 fewer steps/day among those with uncontrolled asthma versus controlled and among those with obese BMI versus nonobese, respectively (both p < 0.05). In regression models adjusted for relevant covariates each 1-unit increase in ACQ score was associated with -686 [95%CI -997, -13] (p ≤ 0.05) average steps/day. The statistical significance of these findings was attenuated (p ≥ 0.05) when BMI was added to the model. However, the point estimate was not reduced (-766 [95%CI -1060, 34]. CONCLUSIONS: Overall step counts were low in this population despite peak cadence values suggesting that most participants could perform moderate intensity activity. Increasing step counts should be considered an important lifestyle intervention goal in obese and non-obese asthma patients with low PA levels.

Research Priorities for Interventions to Address Health Disparities in Lung Nodule Management: An Official American Thoracic Society Research Statement.

Background: Lung nodules are common incidental findings, and timely evaluation is critical to ensure diagnosis of localized-stage and potentially curable lung cancers. Rates of guideline-concordant lung nodule evaluation are low, and the risk of delayed evaluation is higher for minoritized groups. Objectives: To summarize the existing evidence, identify knowledge gaps, and prioritize research questions related to interventions to reduce disparities in lung nodule evaluation. Methods: A multidisciplinary committee was convened to review the evidence and identify key knowledge gaps in four domains: 1) research methodology, 2) patient-level interventions, 3) clinician-level interventions, and 4) health system-level interventions. A modified Delphi approach was used to identify research priorities. Results: Key knowledge gaps included 1) a lack of standardized approaches to identify factors associated with lung nodule management disparities, 2) limited data evaluating the role of social determinants of health on disparities in lung nodule management, 3) a lack of certainty regarding the optimal strategy to improve patient-clinician communication and information transmission and/or retention, and 4) a paucity of information on the impact of patient navigators and culturally trained multidisciplinary teams. Conclusions: This statement outlines a research agenda intended to stimulate high-impact studies of interventions to mitigate disparities in lung nodule evaluation. Research questions were prioritized around the following domains: 1) need for methodologic guidelines for conducting research related to disparities in nodule management, 2) evaluating how social determinants of health influence lung nodule evaluation, 3) studying approaches to improve patient-clinician communication, and 4) evaluating the utility of patient navigators and culturally enriched multidisciplinary teams to reduce disparities.

Race and Ethnicity in Pulmonary Function Test Interpretation: An Official American Thoracic Society Statement.

Current American Thoracic Society (ATS) standards promote the use of race and ethnicity-specific reference equations for pulmonary function test (PFT) interpretation. There is rising concern that the use of race and ethnicity in PFT interpretation contributes to a false view of fixed differences between races and may mask the effects of differential exposures. This use of race and ethnicity may contribute to health disparities by norming differences in pulmonary function. In the United States and globally, race serves as a social construct that is based on appearance and reflects social values, structures, and practices. Classification of people into racial and ethnic groups differs geographically and temporally. These considerations challenge the notion that racial and ethnic categories have biological meaning and question the use of race in PFT interpretation. The ATS convened a diverse group of clinicians and investigators for a workshop in 2021 to evaluate the use of race and ethnicity in PFT interpretation. Review of evidence published since then that challenges current practice and continued discussion concluded with a recommendation to replace race and ethnicity-specific equations with race-neutral average reference equations, which must be accompanied with a broader re-evaluation of how PFTs are used to make clinical, employment, and insurance decisions. There was also a call to engage key stakeholders not represented in this workshop and a statement of caution regarding the uncertain effects and potential harms of this change. Other recommendations include continued research and education to understand the impact of the change, to improve the evidence for the use of PFTs in general, and to identify modifiable risk factors for reduced pulmonary function.

Assessing the interrelationship between asthma and obesity self-management behaviors.

Asthma and obesity are common coexisting conditions with increasing prevalence and substantial morbidity. This study examines the inter-relationship between illness and treatment beliefs in asthma and obesity and how they influence self-management behaviors. Overweight and obese adults ≥ 18 years with asthma were recruited from primary care and pulmonary practices in New York, NY and Denver, CO (n = 219). Path analysis was used to examine the relationship between asthma, weight and exercise-related illness and medication beliefs and SMB. Necessity beliefs about asthma medications and diet were associated with better medication adherence and healthier dietary behaviors (ß = 0.276, p = < 0.001, ß = 0.148, p = 0.018 respectively) whereas concerns about these self-care activities were associated with poorer adherence and worse dietary behaviors (ß = - 0.282, p < 0.001, ß = - 0.188, p = 0.003 respectively). We found no statistically significant association of exercise behaviors with any other weight or asthma illness or treatment beliefs. Our study demonstrates that necessity and concerns about treatment are associated with adherence in asthma and obesity. The lack of association of exercise behaviors with any asthma or weight related beliefs may reflect limited awareness of the impact of weight on asthma and warrants additional research.

Racial and ethnic differences in post-traumatic stress trajectories in breast cancer survivors.

PURPOSE: To describe differences in post-traumatic stress (PTS) symptoms over time among racial and ethnic minoritized breast cancer survivors (BCS) with comorbid diabetes. DESIGN: In a multisite longitudinal study, post-traumatic stress was evaluated at baseline, 6 and 12 months through self-reported questionnaires (Impact of Events Scale-Revised [IES-R]). PARTICIPANTS: One hundred and seventy-eight post-treatment BCS with diabetes were recruited from three tertiary medical centers. FINDINGS: Relative to non-Hispanic White women, minoritized women reported higher total IES-R scores at all time points. In the adjusted model, Latina women reported persistently higher IES-R total scores and Latina, and 'Other' women reported higher avoidance scores. CONCLUSIONS: Minoritized BCS with comorbid diabetes report higher rates of cancer related PTS that persist over 12 months. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS: Post diagnosis PTS evaluation and support is important in survivorship and primary care practices. Linkage to socially and culturally sensitive community support may be warranted.

Rates of Undiagnosed Cognitive Impairment and Performance on the Montreal Cognitive Assessment Among Older Adults in Primary Care.

BACKGROUND: The number of adults in the USA with cognitive impairment is increasing; however, few studies report prevalence rates of undiagnosed cognitive impairment among older adults in primary care. OBJECTIVE: To determine the prevalence of undiagnosed cognitive impairment among adults ages 55 years and older in primary care settings and provide normative data for the Montreal Cognitive Assessment in this context. DESIGN: Single interview, observational study. PARTICIPANTS: English-speaking adults ages 55 years and older without diagnoses of cognitive impairment recruited from primary care practices in New York City, NY, and Chicago, IL (n = 872). MAIN MEASURES: Montreal Cognitive Assessment (MoCA). Undiagnosed cognitive impairment was defined by age and education adjusted z-scores more than 1.0 and 1.5 standard deviations below published norms, corresponding to mild or moderate to severe cognitive impairment, respectively. KEY RESULTS: The mean age was 66.8 (8.0) years, 44.7% were male, 32.9% were Black or African-American, and 29.1% were Latinx. Undiagnosed cognitive impairment was identified in 20.8% of subjects (mild impairment, 10.5%; moderate-severe impairment, 10.3%). Impairment at any level of severity was associated in bivariate analyses with several patient characteristics, most notably for race and ethnicity (White, non-Latinx, 6.9% vs. Black, non-Latinx, 26.8%, Latinx, 28.2%, other race, 21.9%; p < 0.0001), place of birth (US 17.5% vs. non-US 30.7%, p < 0.0001), depression (33.1% vs. no depression, 18.1%; p < 0.0001), and impairment in activities of daily living (≥ 1 ADL impairment, 34.0% vs. no ADL impairment, 18.2%; p < 0.0001). CONCLUSIONS: Undiagnosed cognitive impairment is common among urban dwelling older adults attending primary care practices, and was associated with several patient characteristics, including non-White race and ethnicity and depression. Normative data for the MoCA from this study may serve as a useful resource for studies of similar patient populations.

Greater executive dysfunction in patients post-COVID-19 compared to those not infected.

BACKGROUND: A number of patients post-coronavirus disease-19 (COVID-19) report cognitive impairment (CI), even months after acute infection. We aimed to assess if COVID-19 is associated with increased incidence of CI in comparison to controls. METHODS: We analyzed data from the Mount Sinai Health System Post-COVID-19 Registry in New York City, a prospective cohort of patients post-COVID-19 ≥18 years of age and non-infected controls. CI was defined by scores ≥ 1.0 standard deviation below population norms, and was assessed using well-validated measures of attention, working memory, processing speed, executive functioning/cognitive flexibility, language, learning, and memory. Logistic regression models assessed odds for CI in each domain in patients post-COVID-19 vs. controls after adjusting for potential confounders. In exploratory analyses, we assessed odds for CI by site of acute COVID-19 care as a proxy for disease severity. FINDINGS: 417 patients post-COVID-19 and 151 controls (mean age 49 years, 63% female, 21% Black, 17% Latinx) were included. In adjusted analyses, patients were significantly more likely than controls to have CI in executive functioning (odds ratio [OR]: 2.19; 95% confidence interval [CI]: 1.03 to 4.67), particularly those treated in outpatient (OR: 2.22; 95% CI: 1.02 to 4.82) and inpatient hospital (OR: 3.59; 95% CI: 1.27 to 10.16) settings. There were no significant associations between CI in other domains and history of COVID-19 or site of acute care. INTERPRETATION: Patients post-COVID-19 have greater odds of executive dysfunction, suggesting that focused cognitive screening may be prudent, even in those with mild to moderate disease. Studies should explore the pathophysiology and potential treatments for CI in this population. FUNDING: This work was funded by the Icahn School of Medicine at Mount Sinai.

Preference for and impact of telehealth vs in-person asthma visits among Black and Latinx adults.

BACKGROUND: Black and Latinx adults experience disproportionate asthma-related morbidity and limited specialty care access. The severe acute respiratory syndrome coronavirus 2 pandemic expanded telehealth use. OBJECTIVE: To evaluate visit type (telehealth [TH] vs in-person [IP]) preferences and the impact of visit type on asthma outcomes among Black and Latinx adults with moderate-to-severe asthma. METHODS: For this PREPARE trial ancillary study, visit type preference was surveyed by e-mail or telephone post-trial. Emergency medical record data on visit types and asthma outcomes were available for a subset (March 2020 to April 2021). Characteristics associated with visit type preferences, and relationships between visit type and asthma outcomes (control [Asthma Control Test] and asthma-related quality of life [Asthma Symptom Utility Index]), were tested using multivariable regression. RESULTS: A total of 866 participants consented to be surveyed, with 847 respondents. Among the participants with asthma care experience with both visit types, 42.0% preferred TH for regular checkups, which associated with employment (odds ratio [OR] = 1.61; 95% confidence interval [CI], 1.09-2.39; P = .02), lower asthma medication adherence (OR = 1.06; 95% CI, 1.01-1.11; P = .03), and having more historical emergency department and urgent care asthma visits (OR = 1.10 for each additional visit; 95% CI, 1.02-1.18; P = .02), after adjustment. Emergency medical record data were available for 98 participants (62 TH, 36 IP). Those with TH visits were more likely Latinx, from the Southwest, employed, using inhaled corticosteroid-only controller therapy, with lower body mass index, and lower self-reported asthma medication adherence vs those with IP visits only. Both groups had comparable Asthma Control Test (18.4 vs 18.9, P = .52) and Asthma Symptom Utility Index (0.79 vs 0.84, P = .16) scores after adjustment. CONCLUSION: TH may be similarly efficacious as and often preferred over IP among Black and Latinx adults with moderate-to-severe asthma, especially for regular checkups. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02995733.

The relationship between social support, self-efficacy, and asthma outcomes in older adults.

OBJECTIVE: There has been a call for research examining factors that influence asthma outcomes in older adults because of the notable disparities observed in this age group. Social support and self-efficacy are resources that factor into asthma outcomes. The current study aimed to examine the relationship between these resources (independently and jointly) and asthma control and quality of life. METHODS: Older adults with moderate-severe asthma were recruited from NYC. Data were obtained during in-person interviews via validated measures of social support, asthma self-efficacy, asthma control, and asthma quality of life. Linear regression evaluated self-efficacy in the relationship between social support and asthma outcomes. RESULTS: In a sample of 359 older adults (M = 68.04, 47.9% Hispanic, 26.5% Black, and 25.6% other), social support had an inverse association with asthma control. As social support increased, asthma control decreased (ß = 0.95, t(356) = -3.13, p = .002). Self-efficacy significantly moderated this relationship (ß = 0.01, t(356) = 2.37, p = .018). For individuals with low or moderate asthma self-efficacy, more received social support was associated with worse asthma control (ß = -0.33, t(356) = -4.66, p < .0001; ß = -0.20, t(356) = -3.21, p = .0014, respectively). For individuals with high self-efficacy, no relationship was found between received social support and asthma control (ß = -0.10, t(356)= -1.20, p =.23). For asthma quality of life, higher levels of received social support were associated with worse quality of life (ß = -0.88, t(356) = -2.64, p = .009), but this association was not significantly moderated by self-efficacy (ß = 0.01, t(356) = 1.90, p = .0582). CONCLUSIONS: For older adults with asthma, receiving more social support is associated with worse asthma outcomes, especially for older adults with lower asthma self-efficacy.

Impact of exacerbations on lung function, resource utilization, and productivity: results from an observational, prospective study in adults with uncontrolled asthma.

Background: Exacerbations have a major impact on the well-being of patients with uncontrolled asthma. This study evaluated lung function, healthcare resource utilization (HCRU), and productivity loss following asthma exacerbations.Methods: This single-center, observational, prospective cohort study recruited US patients presenting clinically with an acute asthma exacerbation; a reference group without exacerbations was included for comparison. Lung function (forced expiratory volume in 1 second [FEV1]) was collected at baseline, daily during Month 1, and monthly for Months 2-5, and reported as FEV1 percent predicted (FEV1pp). HCRU (outpatient visits to a healthcare practitioner, emergency room [ER] visits, and hospitalizations for asthma), oral corticosteroid (OCS) use, and asthma-related work/school absence were collected monthly for 6 months.Results: Overall, 150 patients were recruited (exacerbation: n=102; reference: n=48; mean [SD] age: 42.7 [15.2] and 49.6 [12.4] years; female: 73% and 71%). In both groups, similar trends were observed in FEV1, with significant improvement from baseline to Week 1 (p<0.05), followed by a continuous decline. FEV1p was 7.7% lower at baseline and 8.6% lower at Month 5 in the exacerbation group versus the reference group. The exacerbation group had significantly higher rates of OCS prescription during follow-up versus reference group (p=0.04). Over half (52.9%) of patients in the exacerbation group had a recurrent exacerbation during follow-up, increased HCRU (outpatient visits, ER visits, and hospitalizations), and impaired productivity.Conclusion: Although patients with exacerbations had rapid recovery of lung function, this was not maintained and declined faster than in patients without exacerbations. Additionally, patients experienced increased HCRU after exacerbations.

Socioeconomic status associates with worse asthma morbidity among Black and Latinx adults.

BACKGROUND: Asthma disproportionately affects African American/Black (AA/B) and Hispanic/Latinx (H/L) patients and individuals with low socioeconomic status (SES), but the relationship between SES and asthma morbidity within these racial/ethnic groups is inadequately understood. OBJECTIVE: To determine the relationship between SES and asthma morbidity among AA/B and H/L adults with moderate to severe asthma using multidomain SES frameworks and mediation analyses. METHODS: We analyzed enrollment data from the PeRson EmPowered Asthma RElief randomized trial, evaluating inhaled corticosteroid supplementation to rescue therapy. We tested for direct and indirect relationships between SES and asthma morbidity using structural equation models. For SES, we used a latent variable defined by poverty, education, and unemployment. For asthma morbidity, we used self-reported asthma exacerbations in the year before enrollment (corticosteroid bursts, emergency room/urgent care visits, or hospitalizations), and Asthma Control Test scores. We tested for mediation via health literacy, perceived stress, and self-reported discrimination. All models adjusted for age, sex, body mass index, ethnicity, and comorbidities. RESULTS: Among 990 AA/B and H/L adults, low SES (latent variable) was directly associated with hospitalizations (ß = 0.24) and worse Asthma Control Test scores (ß = 0.20). Stress partially mediated the relationship between SES and increased emergency room/urgent care visits and worse asthma control (ß = 0.03 and = 0.05, respectively). Individual SES domains were directly associated with asthma morbidity. Stress mediated indirect associations between low educational attainment and unemployment with worse asthma control (ß = 0.05 and = 0.06, respectively). CONCLUSIONS: Lower SES is directly, and indirectly through stress, associated with asthma morbidity among AA/B and H/L adults. Identification of stressors and relevant management strategies may lessen asthma-related morbidity among these populations.

The indirect influence of 'invisible' support on pulmonary function among adults with chronic obstructive pulmonary disease.

Individuals living with chronic obstructive pulmonary disease (COPD) often require support from family or friends. We examined whether invisible support - support that is provided but goes unnoticed - is related to pulmonary function, and whether this association is mediated by depressive symptoms and illness perceptions. Sixty-six dyads of individuals with COPD and their informal caregivers reported on receipt and provision of support, respectively. Those with COPD completed measures of depressive symptoms, illness perceptions and pulmonary function. Although invisible support was not directly related to pulmonary function, mediation analyses revealed a combined indirect effect through lower depressive symptoms and less negative illness perceptions. Interventions teaching skillful delivery of support to caregivers may reduce depressive symptoms and threatening illness cognitions, which may contribute to improvements in symptom burden among patients with COPD.

Differences in L-arginine metabolism and asthma morbidity among asthma patients with and without obstructive sleep apnea.

BACKGROUND: Imbalance in L-arginine and nitric oxide (NO) metabolism has been implicated in the pathophysiology of asthma and obstructive sleep apnea (OSA), and both diseases impact the other's morbidity. We sought to determine whether L-arginine/NO metabolism differs between adults with asthma with or without comorbid OSA, and its association with asthma morbidity. METHODS: This is a cross-sectional study of 322 adults with asthma recruited in Denver, CO and New York City, NY. Data were collected on OSA status, spirometry, and metrics of asthma control and morbidity. L-Arginine metabolites were quantified in patient serum. Bivariate analyses and multiple regression were performed to determine differences between L-arginine metabolism, OSA and association with asthma morbidity. RESULTS: Among the 322 participants, 92 (28.5%) had OSA. The cohort was 81.6% female, 23.4% identified as Black and 30.6% as Latino. Patients with asthma and OSA had significantly higher serum concentrations of NO synthase inhibitor asymmetric dimethylarginine (ADMA) (p-value = 0.019), lower L-arginine to ornithine ratios (p-value = 0.003), and increased ornithine (p-value = 0.001) and proline levels (p-value < 0.001) compared to those without OSA. In adjusted models, OSA was associated with worse asthma control, adjusted mean difference in asthma control questionnaire of 0.36 (95% confidence interval [CI]: 0.06 to 0.65), and asthma quality of life questionnaire, adjusted mean difference: - 0.53 (95% CI: - 0.85 to - 0.21), after adjusting for relevant covariates including body mass index and L-arginine metabolites. CONCLUSIONS: Adults with asthma and OSA had increased ADMA, an inhibitor of nitric oxide synthase, and greater metabolism of L-arginine via the arginase pathway compared to those with asthma alone, indicating a possible shared pathophysiological mechanism of these diseases.

Association of Vaccination with the Persistence of Post-COVID Symptoms.

BACKGROUND: Patients who have had COVID-19 often report persistent symptoms after resolution of their acute illness. Recent reports suggest that vaccination may be associated with improvement in post-acute symptoms. We used data from a prospective cohort to assess differences in post-acute sequelae of COVID (PASC) among vaccinated vs. unvaccinated patients. METHODS: We used data from a cohort of COVID-19 patients enrolled into a prospective registry established at a tertiary care health system in New York City. Participants underwent a baseline evaluation before COVID-19 vaccines were available and were followed 6 months later. We compared unadjusted and propensity score-adjusted baseline to 6-month change for several PASC-related symptoms and measures: anosmia, respiratory (cough, dyspnea, phlegm, wheezing), depression, anxiety, post-traumatic stress disorder (PTSD; COVID-19-related and other trauma), and quality-of-life domains among participants who received vs. those who did not receive COVID-19 vaccination. RESULTS: The study included 453 COVID-19 patients with PASC, of which 324 (72%) were vaccinated between the baseline and 6-month visit. Unadjusted analyses did not show significant differences in the baseline to 6-month change in anosmia, respiratory symptoms, depression, anxiety, PTSD, or quality of life (p > 0.05 for all comparisons) among vaccinated vs. unvaccinated patients. Similar results were found in propensity-adjusted comparisons and in secondary analyses based on the number of vaccine doses received. CONCLUSIONS: Our findings suggest that COVID vaccination is not associated with improvement in PASC. Additional studies are needed to better understand the mechanisms underlying PASC and to develop effective treatments.
