RESUMO
BACKGROUND: Racial disparities in lung cancer screening (LCS) are well established. Black Veterans are among those at the highest risk for developing lung cancer but are less likely to complete LCS. We sought to identify barriers and facilitators to LCS uptake among Black Veterans. PATIENTS AND METHODS: A qualitative study using semistructured interviews was conducted with 32 Black Veterans to assess for barriers, facilitators, and contextual factors for LCS and strategies to improve screening. Veterans were purposively sampled by age, sex, and LCS participation status (ie, patients who received a low-dose CT [LDCT], patients who contacted the screening program but did not receive an LDCT, and patients who did not connect with the screening program nor receive an LDCT). Interview guides were developed using the Theoretical Domains Framework and Health Belief Model. Data were analyzed using rapid qualitative analysis. RESULTS: Barriers of LCS uptake among Black Veterans include self-reported low LCS knowledge and poor memory, attention, and decision processes associated with the centralized LCS process. Facilitators of LCS uptake among Black Veterans include social/professional role; identity and social influences; perceived susceptibility, threat, and consequences due to smoking status and military or occupational exposures; emotion, behavioral regulation, and intentions; and high trust in providers. Environmental context and resources (eg, transportation) and race and racism serve as contextual factors that did not emerge as having a major impact on LCS uptake. Strategies to improve LCS uptake included increased social messaging surrounding LCS, various forms of information dissemination, LCS reminders, balanced and repeated shared decision-making discussions, and streamlined referrals. CONCLUSIONS: We identified addressable barriers and facilitators for LCS uptake among Black Veterans that can help focus efforts to improve disparities in screening. Future studies should explore provider perspectives and test interventions to improve equity in LCS.

Rationale: Data on risk factors for chronic hypoxemia in low- and middle-income countries are lacking. Objectives: We aimed to quantify the association between potential risk factors and chronic hypoxemia among adults hospitalized in Kenya. Methods: A hospital-based, case-control study was conducted at Moi Teaching and Referral Hospital in Eldoret, Kenya. Adult inpatients were screened on admission and enrolled in a 1:2 case-to-control ratio. Cases were patients with chronic hypoxemia, defined as resting oxygen saturation as measured by pulse oximetry (SpO2) ⩽ 88% on admission and either 1-month postdischarge SpO2 ⩽ 88% or, if they died before follow-up, documented SpO2 ⩽ 88% in the 6 months before enrollment. Control subjects were randomly selected, stratified by sex, among nonhypoxemic inpatients. Data were collected using questionnaires and structured chart review. Regression was used to assess the associations between chronic hypoxemia and age, sex, smoking status, biomass fuel use, elevation, and self-reported history of tuberculosis and human immunodeficiency virus diagnosis. Odds ratios (ORs) and 95% confidence intervals (CIs) are reported. Results: We enrolled 108 chronically hypoxemic cases and 240 nonhypoxemic control subjects into our Chronic Hypoxemia among Kenyan Adults (CHAKA) cohort. In multivariable analysis, compared with control subjects, chronically hypoxemic cases had significantly higher odds of older age (OR, 1.2 per 5-year increase [95% CI, 1.1-1.3]), female sex (OR, 3.6 [95% CI, 1.8-7.2]), current or former tobacco use (OR, 4.7 [95% CI, 2.3-9.6]), and prior tuberculosis (OR, 11.8 [95% CI, 4.7-29.6]) but no increase in the odds of human immunodeficiency virus diagnosis and biomass fuel use. Conclusions: These findings highlight the potential impact of prior tuberculosis on chronic lung disease in Kenya and the need for further studies on posttuberculosis lung disease.

INTRODUCTION: Tuberculosis (TB) is a leading infectious cause of death globally. It is the most common opportunistic infection in people living with HIV, and the most common cause of their morbidity and mortality. Following TB treatment, surviving individuals may be at risk for post-TB lung disease. The TB Sentinel Research Network (TB-SRN) provides a platform for coordinated observational TB research within the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. METHODS AND ANALYSIS: This prospective, observational cohort study will assess treatment and post-treatment outcomes of pulmonary TB (microbiologically confirmed or clinically diagnosed) among 2600 people aged ≥15 years, with and without HIV coinfection, consecutively enrolled at 16 sites in 11 countries, across 6 of IeDEA's global regions. Data regarding clinical and sociodemographic factors, mental health, health-related quality of life, pulmonary function, and laboratory and radiographic findings will be collected using standardised questionnaires and data collection tools, beginning from the initiation of TB treatment and through 12 months after the end of treatment. Data will be aggregated for proposed analyses. ETHICS AND DISSEMINATION: Ethics approval was obtained at all implementing study sites, including the Vanderbilt University Medical Center Human Research Protections Programme. Participants will provide informed consent; for minors, this includes both adolescent assent and the consent of their parent or primary caregiver. Protections for vulnerable groups are included, in alignment with local standards and considerations at sites. Procedures for requesting use and analysis of TB-SRN data are publicly available. Findings from TB-SRN analyses will be shared with national TB programmes to inform TB programming and policy, and disseminated at regional and global conferences and other venues.

Lung cancer screening (LCS) decreases lung cancer related mortality among high-risk people who smoke cigarettes and has been endorsed by the US Preventive Services Task Force (USPSTF) since 2013. However, adoption of LCS has been limited, and disparities in LCS among racially and ethnically minoritized groups have become apparent. While recommendations to improve disparities in LCS have been made, there is a lack of information on how these recommendations have been implemented and their relative effectiveness in improving screening disparities. This scoping review addresses this knowledge gap by examining interventions that have been implemented to improve LCS among racially and ethnically minoritized groups in the United States. A comprehensive search of MEDLINE (via PubMed), EMBASE (via Elsevier), CINAHL Complete (via EBSCO), and Scopus (via Elsevier), for articles from the period 1 January 2010 through 22 October 2021 was completed. Out of 17,045 references screened, only 11 studies describing an intervention to improve disparities in LCS were identified, underscoring the dearth of data on established interventions. The interventions discussed could be categorized into three groups -- patient level (n = 3), clinic/institution level (n = 3), and community level (n = 5) interventions. Of those studies reporting effectiveness data (n = 8), there was substantial heterogeneity in the outcomes measured and their relative effectiveness. We found that interventions which streamlined the LCS process at the level of a single clinic or institution were the most effective in improving LCS. Community-level interventions that focused on engagement and education had the greatest potential to target racially and ethnically minoritized groups. Our study underscores the need for more robust research on addressing barriers to LCS by identifying effective patient, clinic, and community-level interventions to improve LCS disparities and the need for potential standardization of intervention effectiveness outcomes.

This ethnographic study introduces the term "distressed work" to describe the emergence of chronic frictions between moral imperatives for health care workers to keep working and the dramatic increase in distress during the Covid-19 pandemic. Interviews and observant participation conducted in a hospital intensive care unit during the Covid-19 pandemic reveal how health care workers connected job duties with extraordinary emotional, physical, and moral burdens. We explore tensions between perceived obligations of health care professionals and the structural contexts of work. Key findings cluster around the moral imperatives of health care work and the distress that work engendered as work spaces, senses of vocation, patient and family interactions, and end-of-life care shifted. While the danger of working beyond limits has long been an ordinary feature of health care work, it has now become a chronic crisis. Assessing this problem in terms of distressed work and its structural contexts can better address effective, worker-informed responses to current health care labor dilemmas.

Importance: Racial disparities in lung cancer screening (LCS) are often ascribed to barriers such as cost, insurance status, access to care, and transportation. Because these barriers are minimized within the Veterans Affairs system, there is a question of whether similar racial disparities exist within a Veterans Affairs health care system in North Carolina. Objectives: To examine whether racial disparities in completing LCS after referral exist at the Durham Veterans Affairs Health Care System (DVAHCS) and, if so, what factors are associated with screening completion. Design, Setting, and Participants: This cross-sectional study assessed veterans referred to LCS between July 1, 2013, and August 31, 2021, at the DVAHCS. All included veterans self-identified as White or Black and met the US Preventive Services Task Force eligibility criteria as of January 1, 2021. Participants who died within 15 months of consultation or who were screened before consultation were excluded. Exposures: Self-reported race. Main Outcomes and Measures: Screening completion was defined as completing computed tomography for LCS. The associations among screening completion, race, and demographic and socioeconomic risk factors were assessed using logistic regression models. Results: A total of 4562 veterans (mean [SD] age, 65.4 [5.7] years; 4296 [94.2%] male; 1766 [38.7%] Black and 2796 [61.3%] White) were referred for LCS. Of all veterans referred, 1692 (37.1%) ultimately completed screening; 2707 (59.3%) never connected with the LCS program after referral and an informational mailer or telephone call, indicating a critical point in the LCS process. Screening rates were substantially lower among Black compared with White veterans (538 [30.5%] vs 1154 [41.3%]), with Black veterans having 0.66 times lower odds (95% CI, 0.54-0.80) of screening completion after adjusting for demographic and socioeconomic factors. Conclusions and Relevance: This cross-sectional study found that after referral for initial LCS via a centralized program, Black veterans had 34% lower odds of LCS screening completion compared with White veterans, a disparity that persisted even after accounting for numerous demographic and socioeconomic factors. A critical point in the screening process was when veterans must connect with the screening program after referral. These findings may be used to design, implement, and evaluate interventions to improve LCS rates among Black veterans.

Objectives: Determine the prevalence of airway disease (e.g., asthma, airflow obstruction, and eosinophilic airway inflammation) in Kenya, as well as related correlates of airway disease and health-related quality of life. Methods: A three-stage, cluster-randomized cross-sectional study in Uasin Gishu County, Kenya was conducted. Individuals 12 years and older completed questionnaires (including St. George's Respiratory Questionnaire for COPD, SGRQ-C), spirometry, and fractional exhaled nitric oxide (FeNO) testing. Prevalence ratios with 95% confidence intervals (CIs) were calculated. Multivariable models were used to assess correlates of airflow obstruction and high FeNO. Results: Three hundred ninety-two participants completed questionnaires, 369 completed FeNO testing, and 305 completed spirometry. Mean age was 37.5 years; 64% were women. The prevalence of asthma, airflow obstruction on spirometry, and eosinophilic airway inflammation was 21.7%, 12.3% and 15.7% respectively in the population. Women had significantly higher SGRQ-C scores compared to men (15.0 vs. 7.7). Wheezing or whistling in the last year and SGRQ-C scores were strongly associated with FeNO levels >50 ppb after adjusting for age, gender, BMI, and tobacco use. Conclusion: Airway disease is a significant health problem in Kenya affecting a young population who lack a significant tobacco use history.

OBJECTIVE: Global medical oxygen security is limited by knowledge gaps in hypoxaemia burden and oxygen access in low-income and middle-income countries. We examined the prevalence and phenotypic trajectories of hypoxaemia among hospitalised adults in Kenya, with a focus on chronic hypoxaemia. DESIGN: Single-centre, prospective cohort study. SETTING: National tertiary referral hospital in Eldoret, Kenya between September 2019 and April 2022. PARTICIPANTS: Adults (age ≥18 years) admitted to general medicine wards. PRIMARY AND SECONDARY OUTCOME MEASURES: Our primary outcome was proportion of patients who were hypoxaemic (oxygen saturation, SpO2 ≤88%) on admission. Secondary outcomes were proportion of patients with hypoxaemia on admission who had hypoxaemia resolution, hospital discharge, transfer, or death among those with unresolved hypoxaemia or chronic hypoxaemia. Patients remaining hypoxaemic for ≤3 days after admission were enrolled into an additional cohort to determine chronic hypoxaemia. Chronic hypoxaemia was defined as an SpO2 ≤ 88% at either 1-month post-discharge follow-up or, for patients who died prior to follow-up, a documented SpO2 ≤88% during a previous hospital discharge or outpatient visit within the last 6 months. RESULTS: We screened 4104 patients (48.5% female, mean age 49.4±19.4 years), of whom 23.8% were hypoxaemic on admission. Hypoxaemic patients were significantly older and more predominantly female than normoxaemic patients. Among those hypoxaemic on admission, 33.9% had resolution of their hypoxaemia as inpatients, 55.6% had unresolved hypoxaemia (31.0% died before hospital discharge, 13.3% were alive on discharge and 11.4% were transferred) and 10.4% were lost to follow-up. The prevalence of chronic hypoxaemia was 2.1% in the total screened population, representing 8.8% of patients who were hypoxaemic on admission. Chronic hypoxaemia was determined at 1-month post-discharge among 59/86 patients and based on prior documentation among 27/86 patients. CONCLUSION: Hypoxaemia is highly prevalent among adults admitted to a general medicine ward at a national referral hospital in Kenya. Nearly 1 in 11 patients who are hypoxaemic on admission are chronically hypoxaemic.

BACKGROUND: Respiratory diseases are the leading cause of death and disability worldwide. Oxygen is an essential medicine used to treat hypoxemia from respiratory diseases. However, the availability and utilization of oxygen delivery systems for adults in sub-Saharan Africa is not well-described. We aim to identify and describe existing data around oxygen availability and provision for adults in sub-Saharan Africa, determine knowledge or research gaps, and make recommendations for future research and capacity building. METHODS: We systematically searched four databases for articles on April 22, 2020, for variations of keywords related to oxygen with a focus on countries in sub-Saharan Africa. Inclusion criteria were studies that included adults and addressed hypoxemia assessment or outcome, oxygen delivery mechanisms, oxygen availability, oxygen provision infrastructure, and oxygen therapy and outcomes. RESULTS: 35 studies representing 22 countries met inclusion criteria. Availability of oxygen delivery systems ranged from 42%-94% between facilities, with wide variability in the consistency of availability. There was also wide reported prevalence of hypoxemia, with most studies focusing on specific populations. In facilities where oxygen is available, health care workers are ill-equipped to identify adult patients with hypoxemia, provide oxygen to those who need it, and titrate or discontinue oxygen appropriately. Oxygen concentrators were shown to be the most cost-effective delivery system in areas where power is readily available. CONCLUSIONS: There is a substantial need for building capacity for oxygen delivery throughout sub-Saharan Africa. Addressing this critical issue will require innovation and a multi-faceted approach of developing infrastructure, better equipping facilities, and health care worker training.

We assessed the effect of implementing a protocol-directed strategy to determine when patients can be liberated from venovenous extracorporeal membrane oxygenation on extracorporeal membrane oxygenation duration, time to initiation of first sweep-off trial, duration of mechanical ventilation, ICU length of stay, hospital length of stay, and survival to hospital discharge. DESIGN: Single-center retrospective before and after study. SETTING: The medical ICU at an academic medical center. PATIENTS: One-hundred eighty patients with acute respiratory distress syndrome managed with venovenous extracorporeal membrane oxygenation at a single institution from 2013 to 2019. INTERVENTIONS: In 2016, our institution implemented a daily assessment of readiness for a trial off extracorporeal membrane oxygenation sweep gas ("sweep-off trial"). When patients met prespecified criteria, the respiratory therapist performed a sweep-off trial to determine readiness for discontinuation of venovenous extracorporeal membrane oxygenation. MEASUREMENTS AND MAIN RESULTS: Sixty-seven patients were treated before implementation of the sweep-off trial protocol, and 113 patients were treated after implementation. Patients managed using the sweep-off trial protocol had a significantly shorter extracorporeal membrane oxygenation duration (5.5 d [3-11 d] vs 11 d [7-15.5 d]; p < 0.001), time to first sweep-off trial (2.5 d [1-5 d] vs 7.0 d [5-11 d]; p < 0.001), duration of mechanical ventilation (15.0 d [9-31 d] vs 25 d [21-33 d]; p = 0.017), and ICU length of stay (18 d [10-33 d] vs 27.0 d [21-36 d]; p = 0.008). There were no observed differences in hospital length of stay or survival to hospital discharge. CONCLUSIONS: In patients with acute respiratory distress syndrome managed with venovenous extracorporeal membrane oxygenation at our institution, implementation of a daily, respiratory therapist assessment of readiness for a sweep-off trial was associated with a shorter time to first sweep-off trial and shorter duration of extracorporeal membrane oxygenation. Among survivors, the postassessment group had a reduced duration of mechanical ventilation and ICU lengths of stay. There were no observed differences in hospital length of stay or inhospital mortality.
RESUMO
Massive hemoptysis represents a life-threatening disorder that has numerous different causes. The development of recombinant factor concentrates has allowed for novel treatments in this emergency setting. This report describes a patient with chronic thromboembolic pulmonary hypertension who underwent pulmonary thromboendarterectomy. The postoperative course was complicated by massive hemoptysis resulting in severe hypoxemia that required extracorporeal membrane oxygenation and multiple daily blood transfusions. After failure of conservative and interventional approaches, recombinant factor VII was administered by bronchial isolation. After treatment, the patient's hemoptysis dramatically resolved, with eventual hospital discharge and excellent function at follow-up. This case presents the use of intrapulmonary activated factor VII to control massive hemoptysis.

This study qualitatively examines contrasting parental decision-making styles about family food choices and physical activities as well as willingness to change behaviors among Mexican-American and Mexican immigrant mothers and fathers of school-aged children. Twelve sex-specific focus groups were held in English or Spanish in 2012. Qualitative analysis informed by grounded theory examined parenting styles (ie, authoritative, authoritarian, or permissive), barriers to healthy lifestyle, and parents' stage of change about healthy lifestyles. One third of the 33 participating couples were born in Mexico. The majority of mothers and fathers described being permissive and allowing unhealthy food choices, and a minority of mothers reported more authoritarian approaches to promoting a healthier diet for their children. Mothers were more permissive than fathers about family physical activities and less engaged in these activities. Most mothers and fathers described only contemplating a healthier diet and more physical activity, while wanting their children to have a healthier lifestyle. These data suggest that clinicians need to assess and address differential parental roles when promoting a healthy lifestyle for children. Clinicians should also adopt culturally competent approaches to overcome barriers to parental engagement in diverse aspects of a healthy family lifestyle.

A descriptive correlation study was conducted in Hobbs, New Mexico, USA, to find the relationship between backpack use and back and neck pain among adolescent boys and girls. A higher percentage of girls than boys rated their pain as being moderate to extremely strong. The correlation between pain and backpack weight per body mass index among girls was positive and significant, but negative and non-significant among boys. The correlation between pain and backpack weight was positive and non-significant among both boys and girls. The correlation between pain and each of the variables of backpack weight per body weight, backpack weight per height, and backpack weight per body surface area was negative and non-significant among boys, but positive and non-significant among girls. Gender-based research studies with additional variables and safe backpack use education in schools are recommended.
