Design of the SPIROMICS Study of Early COPD Progression: SOURCE Study.

Background: The biological mechanisms leading some tobacco-exposed individuals to develop early-stage chronic obstructive pulmonary disease (COPD) are poorly understood. This knowledge gap hampers development of disease-modifying agents for this prevalent condition. Objectives: Accordingly, with National Heart, Lung and Blood Institute support, we initiated the SubPopulations and InteRmediate Outcome Measures In COPD Study (SPIROMICS) Study of Early COPD Progression (SOURCE), a multicenter observational cohort study of younger individuals with a history of cigarette smoking and thus at-risk for, or with, early-stage COPD. Our overall objectives are to identify those who will develop COPD earlier in life, characterize them thoroughly, and by contrasting them to those not developing COPD, define mechanisms of disease progression. Methods/Discussion: SOURCE utilizes the established SPIROMICS clinical network. Its goal is to enroll n=649 participants, ages 30-55 years, all races/ethnicities, with ≥10 pack-years cigarette smoking, in either Global initiative for chronic Obstructive Lung Disease (GOLD) groups 0-2 or with preserved ratio-impaired spirometry; and an additional n=40 never-smoker controls. Participants undergo baseline and 3-year follow-up visits, each including high-resolution computed tomography, respiratory oscillometry and spirometry (pre- and postbronchodilator administration), exhaled breath condensate (baseline only), and extensive biospecimen collection, including sputum induction. Symptoms, interim health care utilization, and exacerbations are captured every 6 months via follow-up phone calls. An embedded bronchoscopy substudy involving n=100 participants (including all never-smokers) will allow collection of lower airway samples for genetic, epigenetic, genomic, immunological, microbiome, mucin analyses, and basal cell culture. Conclusion: SOURCE should provide novel insights into the natural history of lung disease in younger individuals with a smoking history, and its biological basis.

Qualitative Study of Food Insecurity in Hospitalized Pediatric Patients during the COVID-19 Pandemic.

OBJECTIVES: Food insecurity (FI) is defined as limited or uncertain access to sufficient food for a healthy and active lifestyle. Our objective was to explore how the coronavirus disease 2019 (COVID-19) pandemic affected the FI status of pediatric patients and their families through interviewing caregivers who screen positive for FI. METHODS: Caregivers of all hospitalized patients at a tertiary children's hospital who screen positive for FI with a two-question screening tool were approached about enrolling in the study. Those who consented completed a presurvey and participated in a semistructured individual interview. Interviews were audio recorded, transcribed, and analyzed according to the guidelines of thematic analysis using NVivo 12. RESULTS: Interviews were conducted with 15 caregivers between July 2021 and January 2022. Caregivers were 100% female and 80% Black, 13% White, and 7% Hispanic/Latinx, with a mean age of 33 years. Seventy-three percent did not experience FI until the COVID-19 pandemic. Themes include lost wages, mothers forced out of the workforce due to childcare limitations, inflation and shortages of goods, increased stress/anxiety for caregivers and children, the centrality of extended family support, and the necessity/inadequacy of federal food programs. CONCLUSIONS: The COVID-19 pandemic impacted unemployment and poverty and consequently exacerbated FI. Our findings point to the need to focus on proximal societal solutions, such as federal policies aimed at food assistance and childcare. Understanding the challenges related to FI that caregivers and patients experience can improve screening, support, and treatment of patients presenting for care and inform the design of necessary interventions for individuals and communities beyond COVID-19.

Partnering With Churches to Address COVID-19 Vaccine Hesitancy and Uptake in Trustworthy Contexts.

The Black church has long been seen as a crucial partner in addressing public health issues. This paper describes the development, implementation, and evaluation of a community-engaged church intervention addressing COVID-19 vaccine hesitancy in underserved Black communities in Jefferson County, Alabama. We partnered with churches to implement and evaluate the intervention between March and June of 2022 and found that our church partners were capable of significant messaging reach, particularly through electronic means.

Community perceptions of contributors and solutions related to neighborhood violent crime: A qualitative interview study.

The current study is part of a community engaged planning phase and aimed to identify perceptions related to the prevalence of violent crime, crime contributors, the relationship between the community and law enforcement, and potential interventions and solutions. In March 2021, semistructured interviews were conducted with individuals from five groups who resided or worked in Bessemer, Alabama: (1) Law Enforcement, (2) Residents, (3) Civic Leaders, (4) Community Leaders, and (5) Victims of Crime. Interviews lasted approximately 60 min and were audio recorded, transcribed, and analyzed according to the guidelines of thematic analysis using NVivo 12. Emerging themes were examined in accordance with the CDC Social-Ecological Model: A Framework for Prevention. Participants (N = 18) were 50.0% female and 77.8% African American with an age range of 25-59 (mean = 43.4 years). Themes that emerged related to crime were: (1) impact, (2) contributors, and (3) solutions. Results indicate that impacts of violent crime at the individual level focused on fear, which led to widespread mental health issues. Relationship level impacts included a lack of trust of law enforcement and neighbors, and community level impacts were decreased neighborhood social cohesion as well as decreased safety. At the societal level, the poor reputation of the city was consistently highlighted. For contributors of crime, being a youth under age 30, drugs, and money were discussed as factors at the individual level. At the relationship level, participants mentioned poor parenting and gangs as crime contributing factors to violent crime. Furthermore, contributing issues related to underresourced schools as well as a poor relationship with law enforcement were brought up at the community level. Similarly, poverty was the overarching contributing issue at the societal level. Solutions that emerged included: education and training in life skills, focusing on young people, family/parenting, conflict resolution programs, programs within schools, improved relationships with law enforcement, and inclusive economic opportunities. Intervention plans are discussed that can merge these stakeholder findings with other data sources.

Development of a comprehensive survey to assess key socioecological determinants of health.

BACKGROUND: Although disparities in surgical outcomes are well-documented, our understanding of how socioecological factors drive these disparities remains limited. Comprehensive and efficient assessment tools are needed. This study's objective was to develop and assess the acceptability and feasibility of a comprehensive tool evaluating socioecological determinants of health in patients requiring colorectal surgery. METHODS: In the first phase, a comprehensive socioecological determinant of health assessment tool was developed. A review of validated socioecological health evaluation instruments was conducted, and a 2-step modified Delphi method addressed the length, clarity, appropriateness, and redundancy of each instrument. A comprehensive tool was then finalized. In the second phase, the tool was tested for acceptability and feasibility in adult patients requiring colorectal surgery using a theory-guided framework at 3 Alabama hospitals. Relationships between survey responses and measures of acceptability and feasibility were evaluated using results from initial pilot tests of the survey. RESULTS: In Phase 1, a modified Delphi process led to the development of a comprehensive tool that included 31 socioecological determinants of health (88 questions). Results of acceptability and feasibility were globally positive (>65%) for all domains. Overall, 83% of participants agreed that others would have no trouble completing the survey, 90.4% of respondents reported the survey was not burdensome, 97.6% of patients reported having enough time to complete the survey, and 80.9% agreed the survey was well-integrated into their appointment. CONCLUSION: An 88-item assessment tool measuring 31 socioecological determinants of health was developed with high acceptability and feasibility for patients who required colorectal surgery. This work aids in the development of research needed to understand and address surgical disparities.

Physical Activity among Colorectal Cancer Patients and Survivors in Egypt.

INTRODUCTION: Understanding physical activity (PA) levels is important when developing tertiary cancer prevention interventions, especially in Egypt where colorectal cancer (CRC) is more often diagnosed at later stages and at a younger age of onset (≤40 years). METHODS: We assessed PA levels among CRC patients and survivors in Alexandria, Egypt. All participants completed two self-reported PA assessments: Global Physical Activity Questionnaire (GPAQ) and Godin Leisure-Time Exercise Questionnaire (GLTEQ). Participants could opt to wear an accelerometer for seven days. Results were compared against WHO recommendations of ≥150 minutes or ≥600 metabolic equivalents of tasks (METs) of moderate-to-vigorous PA weekly. RESULTS: Of 86 participants enrolled, all completed the surveys and 29 agreed to accelerometer use. Prevalence of meeting PA recommendations was 62.8% based on the GPAQ, 14.0% based on GLTEQ, and 41% based on accelerometer. Based on the GPAQ, very few respondents reported vigorous occupational, vigorous recreational, or moderate recreational activity (median = 0 with interquartile range [IQR] of 0 - 0 weekly minutes for all three) while most activity resulted from moderate occupational and transportation (median [IQR] of 60 [0-840] and 60 [0-187.5] weekly minutes, respectively). Participants meeting PA recommendations were less likely to be married (p = 0.043) according to GPAQ and more likely to be female (p=0.047) and early cancer stage (p=0.007) by GLTEQ. CONCLUSION: Non-leisure free-living PA is a major contributor to meeting PA recommendations while leisure-time PA is a potential target for future interventions that increase PA in this population.

Microbiome diversity in African American, European American, and Egyptian colorectal cancer patients.

Purpose: Although there is an established role for microbiome dysbiosis in the pathobiology of colorectal cancer (CRC), CRC patients of various race/ethnicities demonstrate distinct clinical behaviors. Thus, we investigated microbiome dysbiosis in Egyptian, African American (AA), and European American (EA) CRC patients. Patients and methods: CRCs and their corresponding normal tissues from Egyptian (n = 17) patients of the Alexandria University Hospital, Egypt, and tissues from AA (n = 18) and EA (n = 19) patients at the University of Alabama at Birmingham were collected. DNA was isolated from frozen tissues, and the microbiome composition was analyzed by 16S rRNA sequencing. Differential microbial abundance, diversity, and metabolic pathways were identified using linear discriminant analysis (LDA) effect size analyses. Additionally, we compared these profiles with our previously published microbiome data derived from Kenyan CRC patients. Results: Differential microbiome analysis of CRCs across all racial/ethnic groups showed dysbiosis. There were high abundances of Herbaspirillum and Staphylococcus in CRCs of Egyptians, Leptotrichia in CRCs of AAs, Flexspiria and Streptococcus in CRCs of EAs, and Akkermansia muciniphila and Prevotella nigrescens in CRCs of Kenyans (LDA score >4, adj. p-value <0.05). Functional analyses showed distinct microbial metabolic pathways in CRCs compared to normal tissues within the racial/ethnic groups. Egyptian CRCs, compared to normal tissues, showed lower l-methionine biosynthesis and higher galactose degradation pathways. Conclusions: Our findings showed altered mucosa-associated microbiome profiles of CRCs and their metabolic pathways across racial/ethnic groups. These findings provide a basis for future studies to link racial/ethnic microbiome differences with distinct clinical behaviors in CRC.

A signature of Prevotella copri and Faecalibacterium prausnitzii depletion, and a link with bacterial glutamate degradation in the Kenyan colorectal cancer patients.

Background: Colorectal cancer (CRC) is the fifth most diagnosed cancer in Sub-Saharan Africa. In Kenya, CRC incidence rates tripled from 1997 to 2017. In the Moi Teaching and Referral Hospital, Moi University, there has been an increase in CRC cases, notably for younger patients. A suggested pathobiology for this increase is gut microbiome dysbiosis. Since, for the Kenyan CRC patient population, microbiome studies are rare, there is a need for a better understanding of how microbiome dysbiosis influences CRC epidemiology in Kenya. In this single-center study, the focus was on profiling the gut microbiome of Kenyan CRC patients and healthy volunteers and evaluating associations between microbiome profiles and the age of CRC patients. Methods: The gut mucosa-associated microbiome of 18 CRC patients and 18 healthy controls were determined by 16S rRNA sequencing and analyzed for alpha and beta diversity, differential abundance, and microbial metabolic profiling. Results: Alpha diversity metrics showed no significant differences, but beta diversity metrics showed dissimilarities in the microbial communities between CRC patients and healthy controls. The most underrepresented species in the CRC group were Prevotella copri (P. copri) and Faecalibacterium prausnitzii (F. prausnitzii), although Bacteroides fragilis (B. fragilis) and Prevotella nigrescens were overrepresented (linear discriminant analysis, LDA score >2, P<0.05). Also, for CRC patients, significant metagenomic functional alterations were evident in microbial glutamate metabolic pathways (L-glutamate degradation VIII was enriched, and L-glutamate and L-glutamine biosynthesis were diminished) (P<0.05, log2 Fold Change >1). Moreover, the microbiome composition was different for patients under 40 years of age compared to older patients (LDA score >2, P<0.05). Conclusions: Microbiome and microbial metabolic profiles of CRC patients are different from those of healthy individuals. CRC microbiome dysbiosis, particularly P. copri and F. prausnitzii depletion and glutamate metabolic alterations, are evident in Kenyan CRC patients.

Using Intervention Mapping to Develop a Theory-Based Intervention to Promote Colorectal Cancer Screening in Egypt.

BACKGROUND: Colorectal cancer (CRC) incidence and mortality rates are increasing in Egypt. Because no national screening guidelines exist, developing an effective evidence-based screening intervention could lower rates by early detection of pre-cancerous and cancerous lesions and polyps. This paper describes the development of a CRC screening intervention in Alexandria, Egypt using Intervention Mapping (IM). MATERIALS AND METHODS: Between September 2019 and March 2020, the successive steps of the IM process were completed. Beginning with the needs assessment, we conducted a literature review, held focus groups with residents of Alexandria, and conducted interviews with local gastroenterologists and oncologists. Program objectives and target audience were determined before designing the program components and implementation plan. Using the PRECEDE-PROCEED theoretical model, predisposing, reinforcing, and enabling screening barriers were assessed. Finally, we developed a Standard Operating Procedures manual detailing aspects of the intervention and evaluation to serve as a model for an expanded screening program. RESULTS: The needs assessment, e.g., literature review, seven focus groups (N=61 participants) and interviews (N=17 participants), indicated that barriers among residents included CRC knowledge deficits, fear/anxiety regarding testing, high cost, and lack of accessibility. Physicians believed CRC testing should only be performed for high risk individuals. Findings from each step of the process informed successive steps. Our final intervention consisted of training components for medical students (Health Champions) who would deliver the intervention to patients in primary care waiting rooms, providing short descriptions of CRC risks and screening, educational brochures, and distributing vouchers for no-cost guaiac fecal occult blood test kits. Health Champions would then follow up with the patients, providing results and referrals for no-cost colonoscopy testing for those with abnormal results. CONCLUSION: Utilizing the IM steps successfully led to development of a theory-based CRC screening intervention for Egypt. Next steps include the implementation of a feasibility pilot intervention.

Reversible Airflow Obstruction Predicts Future Chronic Obstructive Pulmonary Disease Development in the SPIROMICS Cohort: An Observational Cohort Study.

Rationale: Chronic obstructive pulmonary disease (COPD) is defined by fixed spirometric ratio, FEV1/FVC < 0.70 after inhaled bronchodilators. However, the implications of variable obstruction (VO), in which the prebronchodilator FEV1/FVC ratio is less than 0.70 but increases to 0.70 or more after inhaled bronchodilators, have not been determined. Objectives: We explored differences in physiology, exacerbations, and health status in participants with VO compared with reference participants without obstruction. Methods: Data from the SPIROMICS (Subpopulations and Intermediate Outcome Measures in COPD Study) cohort were obtained. Participants with VO were compared with reference participants without obstruction. Measurements and Main Results: We assessed differences in baseline radiographic emphysema and small airway disease at study entry, baseline, and change in lung function by spirometry, functional capacity by 6-minute walk, health status using standard questionnaires, exacerbation rates, and progression to COPD between the two groups. All models were adjusted for participant characteristics, asthma history, and tobacco exposure. We assessed 175 participants with VO and 603 reference participants without obstruction. Participants with VO had 6.2 times the hazard of future development of COPD controlling for other factors (95% confidence interval, 4.6-8.3; P < 0.001). Compared with reference participants, the VO group had significantly lower baseline pre- and post-bronchodilator (BD) FEV1, and greater decline over time in post-BD FEV1, and pre- and post-BD FVC. There were no significant differences in exacerbations between groups. Conclusions: Significant risk for future COPD development exists for those with pre- but not post-BD airflow obstruction. These findings support consideration of expanding spirometric criteria defining COPD to include pre-BD obstruction. Clinical trial registered with www.clinicaltrials.gov (NCT01969344).

Forced Expiratory Flow at 25%-75% Links COPD Physiology to Emphysema and Disease Severity in the SPIROMICS Cohort.

BACKGROUND: Forced expiratory volume in 1 second (FEV1) is central to the diagnosis of chronic obstructive pulmonary disease (COPD) but is imprecise in classifying disease burden. We examined the potential of the maximal mid-expiratory flow rate (forced expiratory flow rate between 25% and 75% [FEF25%-75%]) as an additional tool for characterizing pathophysiology in COPD. OBJECTIVE: To determine whether FEF25%-75% helps predict clinical and radiographic abnormalities in COPD. STUDY DESIGN AND METHODS: The SubPopulations and InteRediate Outcome Measures In COPD Study (SPIROMICS) enrolled a prospective cohort of 2978 nonsmokers and ever-smokers, with and without COPD, to identify phenotypes and intermediate markers of disease progression. We used baseline data from 2771 ever-smokers from the SPIROMICS cohort to identify associations between percent predicted FEF25%-75% (%predFEF25%-75%) and both clinical markers and computed tomography (CT) findings of smoking-related lung disease. RESULTS: Lower %predFEF25-75% was associated with more severe disease, manifested radiographically by increased functional small airways disease, emphysema (most notably with homogeneous distribution), CT-measured residual volume, total lung capacity (TLC), and airway wall thickness, and clinically by increased symptoms, decreased 6-minute walk distance, and increased bronchodilator responsiveness (BDR). A lower %predFEF25-75% remained significantly associated with increased emphysema, functional small airways disease, TLC, and BDR after adjustment for FEV1 or forced vital capacity (FVC). INTERPRETATION: The %predFEF25-75% provides additional information about disease manifestation beyond FEV1. These associations may reflect loss of elastic recoil and air trapping from emphysema and intrinsic small airways disease. Thus, %predFEF25-75% helps link the anatomic pathology and deranged physiology of COPD.

Amount and intensity effects of exercise training alone versus a combined diet and exercise lifestyle intervention on health-related quality of life in the STRRIDE-PD randomized trial.

INTRODUCTION: To determine the relative contributions of various amounts and intensities of exercise alone to a combined lifestyle intervention on health-related quality of life (HrQoL) measures. RESEARCH DESIGN AND METHODS: Participants (n=162) were sedentary, overweight/obese, with pre-diabetes, and randomized to one of four 6-month interventions: (1) high amount/moderate intensity exercise-energy expenditure of 16 kcal/kg of body weight/week (KKW) at 50% oxygen consumption (V̇O2) reserve; (2) high/vigorous-16 KKW at 75% V̇O2 reserve; (3) low/moderate-10 KKW at 50% V̇O2 reserve; (4) low/moderate plus diet-10 KKW at 50% V̇O2 reserve plus a calorically restricted diet. The 36-Item Short-Form Survey (SF-36) and Satisfaction with Physical Function and Appearance (SPF/SPA) survey were assessed at baseline and post-intervention. Analyses of covariance determined differences in change scores among groups (p<0.05). Paired t-tests determined significant pre-intervention versus post-intervention scores within groups (p<0.05). RESULTS: Across the intervention, all groups (p<0.05) improved the physical component, SPF, and SPA scores. Only the low/moderate/diet group (p<0.001) significantly improved the mental component score. The high/vigorous group achieved 84.5% of the low/moderate/diet group effect for change in physical component score, and the low/moderate group achieved 83.7% of the low/moderate/diet group effect for change in mental component score. CONCLUSIONS: In general, a low amount of moderate intensity exercise combined with diet was the most effective intervention for improving HrQoL. Of the exercise-only interventions, vigorous intensity exercise provided the greatest impact on changes in physical function. On the other hand, low amounts of moderate intensity exercise provided the greatest impact on mental well-being, potentially being a more attainable exercise dose for previously sedentary individuals with pre-diabetes to achieve.

Exploring COVID-19 Vaccine Hesitancy Among Stakeholders in African American and Latinx Communities in the Deep South Through the Lens of the Health Belief Model.

PURPOSE: The purpose of this study was to qualitatively explore perceptions related to COVID-19 vaccination intention among African American and Latinx participants and suggest intervention strategies. APPROACH: Ninety minute virtual focus groups (N = 8), segmented by county, race and ethnicity were conducted with stakeholders from 3 vulnerable Alabama counties. PARTICIPANTS: Participants (N = 67) were primarily African American and Latinx, at least 19 years, and residents or stakeholders in Jefferson, Mobile, and Dallas counties. SETTING: Focus groups took place virtually over Zoom. METHODS: The semi-structured guide explored perceptions of COVID-19, with an emphasis on barriers and facilitators to vaccine uptake. Focus groups lasted approximately 90 minutes and were audio recorded, transcribed, and analyzed by a team of 3 investigators, according to the guidelines of Thematic Analysis using NVivo 12. To provide guidance in the development of interventions to decrease vaccine hesitancy, we examined how themes fit with the constructs of the Health Belief Model. RESULTS: We found that primary themes driving COVID-19 vaccine hesitancy, ordered from most to least discussed, are mistrust, fear, and lack of information. Additionally, interventions to decrease vaccine hesitancy should be multi-modal, community engaged, and provide consistent, comprehensive messages delivered by trusted sources.

Barriers and Facilitators to Bikeshare Programs: A Qualitative Study in an Urban Environment.

INTRODUCTION: Bikeshare programs have emerged across the US to promote bicycling as an active mode of transportation that could potentially improve health and quality of life. However, bikeshare usage is low in some settings. The purpose of this qualitative study is to explore barriers and facilitators of bikeshare use and to identify potential strategies to increase participation in urban environments. METHODS: Focus groups were conducted with urban bikeshare users in Birmingham, Alabama. Thematic analysis was guided by the PRECEDE model, which identifies predisposing (intrapersonal), reinforcing (interpersonal), and enabling (structural) factors related to a health program. RESULTS: In the four focus groups, the most prominent barriers to utilization identified were age, disability, stigma, and lack of awareness of programs (intrapersonal), having small children (interpersonal), lack of safety and bicycling infrastructure, bikeshare characteristics such as location, time constraints, cost, ease of use, and availability of bikes (structural). The most prominent facilitators included enjoyment (intrapersonal), peer support (interpersonal), and convenience, location, cost, and availability of electric bikes (structural). Recommendations to increase usage were primarily structural, such as infrastructure improvement, incentive programs, awareness and safety campaigns, expansion to neighborhoods and trails, increasing time users can ride before docking, and providing more electric bikes. CONCLUSION: To increase bikeshare use in urban settings, use-restricting policies must be addressed.

Aerobic Versus Resistance Training Effects on Ventricular-Arterial Coupling and Vascular Function in the STRRIDE-AT/RT Trial.

Background: The goal was studying the differential effects of aerobic training (AT) vs. resistance training (RT) on cardiac and peripheral arterial capacity on cardiopulmonary (CP) and peripheral vascular (PV) function in sedentary and obese adults. Methods: In a prospective randomized controlled trial, we studied the effects of 6 months of AT vs. RT in 21 subjects. Testing included cardiac and vascular ultrasoundography and serial CP for ventricular-arterial coupling (Ees/Ea), strain-based variables, brachial artery flow-mediated dilation (BAFMD), and peak VO2 (pVO2; mL/kg/min) and peak O2-pulse (O2p; mL/beat). Results: Within the AT group (n = 11), there were significant increases in rVO2 of 4.2 mL/kg/min (SD 0.93) (p = 0.001); O2p of 1.9 mL/beat (SD 1.3) (p = 0.008) and the brachial artery post-hyperemia peak diameter 0.18 mm (SD 0.08) (p = 0.05). Within the RT group (n = 10) there was a significant increase in left ventricular end diastolic volume 7.0 mL (SD 9.8; p = 0.05) and percent flow-mediated dilation (1.8%) (SD 0.47) (p = 0.004). Comparing the AT and RT groups, post exercise, rVO2 2.97, (SD 1.22), (p = 0.03), O2p 0.01 (SD 1.3), (p = 0.01), peak hyperemic blood flow volume (1.77 mL) (SD 140.69) (p = 0.009), were higher in AT, but LVEDP 115 mL (SD 7.0) (p = 0.05) and Ees/Ea 0.68 mmHg/ml (SD 0.60) p = 0.03 were higher in RT. Discussion: The differential effects of AT and RT in this hypothesis generating study have important implications for exercise modality and clinical endpoints.

Confronting COVID-19 in under-resourced, African American neighborhoods: a qualitative study examining community member and stakeholders' perceptions.

OBJECTIVE: The purpose of this study was to examine perceptions of COVID-19 related to prevention, coping, and testing of African American residents in under-resourced communities in Alabama. DESIGN: Guided by the PRECEDE-PROCEED model, virtual focus groups were conducted in five urban and rural Alabama communities using secure Zoom meetings. Community residents and stakeholders (N = 36 total) participated; meetings were audio- and video-recorded, transcribed, and analyzed according to Thematic Analysis. Themes were organized by the PRECEDE portion of the model in Predisposing, Reinforcing, and Enabling barriers and facilitators in three focus areas: prevention, coping, and testing. RESULTS: Prevention barriers included apathy, difficulty with social distancing, lack of information, mixed messages from authority figures, and lack of personal protective equipment (PPE). Prevention facilitators included concerns about contracting COVID-19, clear and consistent messages from trusted sources, contact tracing, and the provision of PPE. Coping barriers included food insecurity, mental health issues, isolation, economic hardships, lack of health care access, and issues with virtual schooling and church services, which were exacerbated by the inability to connect to the internet. Facilitators to coping included religious faith, increased physical activity, and a sense of hope. Testing barriers included misunderstanding, fear, mistrust, testing restrictions, and location of testing sites. Facilitators to testing included incentives, clear information from trusted sources, convenient testing locations, and free tests. CONCLUSION: Gaining community members' perspectives can identify barriers and facilitators to prevention, coping, and testing and potentially improve outcomes. While addressing the social determinants of health (e.g. income, education, medical trust) would be an effective path by which to diminish health disparities related to COVID-19, there is an urgent need to mitigate the spread and severity of COVID-19 in vulnerable populations. Interventions should focus on downstream determinants, such as those emerging from our study.

Barriers to Advancement in Academic Medicine: the Perception Gap Between Majority Men and Other Faculty.

BACKGROUND: According to the American Association of Medical Colleges, women comprise 26% of full professors and 19% of medical school department chairs. African American and Latino faculty comprise 4.6% of full professors and 6.9% of department chairs. OBJECTIVE: Because of the lack of representation of women and racial/ethnic minority faculty at the highest levels of academic medicine, this study examines the perceptions of barriers to advancement by men and women academic medical school faculty of differing races and ethnicities to explore potential differences in perceptions by demographic group. DESIGN: Semi-structured one-on-one interviews were conducted between July and September 2017. PARTICIPANTS: In order to give all faculty a chance to participate, faculty of all ranks and specialties were recruited from one southeastern medical school to participate in the study. APPROACH: Interviews were audio recorded, transcribed, and analyzed by 3 members of the research team using an inductive approach to thematic analysis. Participants were organized into 4 groups for analysis-underrepresented in medicine (URiM) women, majority women, URiM men, majority men. KEY RESULTS: Sixty-four faculty consented to participate in the study (56.2% women, 34.4% URiM). Subthemes were grouped under three main themes: Perceptions of Barriers to Advancement of Women Faculty, Perceptions of Barriers to Advancement of African American and Latino Faculty, and Perceptions of the Institutional Climate for Diversity. Majority men tended to voice distinctly different perspectives than the other three demographic groups, with the most notable differences between majority men and URiM women. Majority  men tended to suggest that the advancement of women and URiM faculty was acceptable or getting better, the lack of URiM faculty in leadership was due mainly to pipeline issues, and women choose not to advance to leadership positions. CONCLUSION: We found that participant gender and race/ethnicity shaped perspectives of medical school faculty advancement in distinct ways.

Designing an Effective Colorectal Cancer Screening Program in Egypt: A Qualitative Study of Perceptions of Egyptian Primary Care Physicians and Specialists.

BACKGROUND: In Egypt more than one-third of colorectal cancer (CRC) cases occur in individuals aged 40 years and younger, and are diagnosed at advanced stages; currently, CRC screening is not done as a routine part of preventive care. To lay the foundation for the development of a CRC multilevel screening program in Egypt, this qualitative study aimed to explore the perspectives of Egyptian physicians. MATERIALS AND METHODS: The PRECEDE-PROCEED model, which focuses on predisposing (intrapersonal), reinforcing (interpersonal), and enabling (structural) factors inherent in health behaviors, served as our theoretical framework. Primary health care physicians, oncologists, and gastroenterologists practicing in Alexandria, Egypt, participated in 1 one-hour semistructured interview. Interviews were audio recorded, transcribed, translated into English, and analyzed by thematic analysis. RESULTS: Seventeen physicians participated (n = 8 specialists and n = 9 primary care physicians). Barriers to CRC screening included socioeconomic status, a lack of emphasis on prevention, fear, and cost (predisposing); a belief that only high risk patients should be screened and a lack of confidence in providers to perform and interpret screening tests appropriately (reinforcing); and cost, lack of availability of the tests, and inadequate training for laboratory technicians and providers (enabling). Potential facilitators included implementing a media campaign emphasizing early detection, curability and prevention (predisposing); educating physicians and eliciting physician engagement (reinforcing); and decreasing costs, making screening tests widely available, and providing well-trained providers (enabling). CONCLUSION: A CRC screening program is needed in Egypt, and to be successful it would likely need to address barriers at multiple levels. IMPLICATIONS FOR PRACTICE: In Egypt, colorectal screening is not a routine part of preventive care, and colorectal cancer is often diagnosed at an advanced stage in individuals aged 40 years or younger. Screening can prevent and detect colorectal cancer in its early stages, but before designing any screening program, understanding the context is important as cultural beliefs may impact the acceptability of screening methods. By exploring the perspectives of Egyptian physicians, this study found important insights into how screening program components should be considered in the Egyptian culture and lays the foundation for the development of a multilevel colorectal screening program in Egypt.
