Identifying priority areas to support primary care engagement in breast cancer survivorship care: A Delphi study.

INTRODUCTION: Existing approaches in cancer survivorship care delivery have proven to be insufficient to engage primary care. This study aimed to identify stakeholder-informed priorities to improve primary care engagement in breast cancer survivorship care. METHODS: Experts in U.S. cancer survivorship care delivery were invited to participate in a 4-round online Delphi panel to identify and evaluate priorities for defining and fostering primary care's engagement in breast cancer survivorship. Panelists were asked to identify and then assess (ratings of 1-9) the importance and feasibility of priority items to support primary care engagement in survivorship. Panelists were asked to review the group results and reevaluate the importance and feasibility of each item, aiming to reach consensus. RESULTS: Respondent panelists (n = 23, response rate 57.5%) identified 31 priority items to support survivorship care. Panelists consistently rated three items most important (scored 9) but with uncertain feasibility (scored 5-6). These items emphasized the need to foster connections and improve communication between primary care and oncology. Panelists reached consensus on four items evaluated as important and feasible: (1) educating patients on survivorship, (2) enabling screening reminders and monitoring alerts in the electronic medical record, (3) identifying patient resources for clinicians to recommend, and (4) distributing accessible reference guides of common breast cancer drugs. CONCLUSION: Role clarity and communication between oncology and primary care were rated as most important; however, uncertainty about feasibility remains. These findings indicate that cross-disciplinary capacity building to address feasibility issues may be needed to make the most important priority items actionable in primary care.

Ambient heat exposure patterns and emergency department visits and hospitalizations among medicare beneficiaries 2008-2019.

OBJECTIVE: To assess the association between ambient heat and all-cause and cause-specific emergency department (ED) visits and acute hospitalizations among Medicare beneficiaries in the conterminous United States. DESIGN: Retrospective cohort study. SETTING: Conterminous US from 2008 and 2019. PARTICIPANTS: 2% random sample of all Medicare fee-for-service beneficiaries eligible for Parts A, B, and D. MAIN OUTCOME MEASURES: All-cause and cause-specific (cardiovascular, renal, and heat-related) ED visits and unplanned hospitalizations were identified using primary ICD-9 or ICD-10 diagnosis codes. We measured the association between ambient temperature - defined as daily mean temperature percentile of summer (June through September) - and the outcomes. Hazard ratios and their associated 95% confidence intervals were estimated using multivariable Cox proportional hazards regression, adjusting for individual level demographics, comorbidities, healthcare utilization factors and zip-code level social factors. RESULTS: Among 809,636 Medicare beneficiaries (58% female, 81% non-Hispanic White, 24% <65), older beneficiaries (aged ≥65) exposed to >95th percentile temperature had a 64% elevated adjusted risk of heat-related ED visits (HR [95% CI], 1.64 [1.46,1.85]) and a 4% higher risk of all-cause acute hospitalization (1.04 [1.01,1.06]) relative to <25th temperature percentile. Younger beneficiaries (aged <65) showed increased risk of heat-related ED visits (2.69 [2.23,3.23]) and all-cause ED visits (1.03 [1.01,1.05]). The associations with heat related events were stronger in males and individuals dually eligible for Medicare and Medicaid. No significant differences were observed by climatic region. We observed no significant relationship between temperature percentile and risk of CV-related ED visits or renal-related ED visits. CONCLUSIONS: Among Medicare beneficiaries from 2008 to 2019, exposure to daily mean temperature ≥ 95th percentile was associated with increased risk of heat-related ED visits, with stronger associations seen among beneficiaries <65, males, and patients with low socioeconomic position. Further longitudinal studies are needed to understand the impact of heat duration, intensity, and frequency on cause-specific hospitalization outcomes.

Air pollution and serious bleeding events in high-risk older adults.

IMPORTANCE: Despite biological plausibility, very few epidemiologic studies have investigated the risks of clinically significant bleeding events due to particulate air pollution. OBJECTIVE: To measure the independent and synergistic effects of PM2.5 exposure and anticoagulant use on serious bleeding events. DESIGN: Retrospective cohort study (2008-2016). SETTING: Nationwide Medicare population. PARTICIPANTS: A 50% random sample of Medicare Part D-eligible Fee-for-Service beneficiaries at high risk for cardiovascular and thromboembolic events. EXPOSURES: Fine particulate matter (PM2.5) and anticoagulant drugs (apixaban, dabigatran, edoxaban, rivaroxaban, or warfarin). MAIN OUTCOMES AND MEASURES: The outcomes were acute hospitalizations for gastrointestinal bleeding, intracranial bleeding, or epistaxis. Hazard ratios and 95% CIs for PM2.5 exposure were estimated by fitting inverse probability weighted marginal structural Cox proportional hazards models. The relative excess risk due to interaction was used to assess additive-scale interaction between PM2.5 exposure and anticoagulant use. RESULTS: The study cohort included 1.86 million high-risk older adults (mean age 77, 60% male, 87% White, 8% Black, 30% anticoagulant users, mean PM2.5 exposure 8.81 µg/m3). A 10 µg/m3 increase in PM2.5 was associated with a 48% (95% CI: 45%-52%), 58% (95% CI: 49%-68%) and 55% (95% CI: 37%-76%) increased risk of gastrointestinal bleeding, intracranial bleeding, and epistaxis, respectively. Significant additive interaction between PM2.5 exposure and anticoagulant use was observed for gastrointestinal and intracranial bleeding. CONCLUSIONS: Among older adults at high risk for cardiovascular and thromboembolic events, increasing PM2.5 exposure was significantly associated with increased risk of gastrointestinal bleeding, intracranial bleeding, and epistaxis. In addition, PM2.5 exposure and anticoagulant use may act together to increase risks of severe gastrointestinal and intracranial bleeding. Thus, clinicians may recommend that high-risk individuals limit their outdoor air pollution exposure during periods of increased PM2.5 concentrations. Our findings may inform environmental policies to protect the health of vulnerable populations.

Painting the Way Forward: An Ecological Cultural Visual Analysis of Anti-VAW Public Art in Rural Ecuador.

Despite efforts within Ecuador to combat violence against women (VAW), the country still claims some of the highest rates of violence in the Americas. In this study, we complete a cultural visual analysis of anti-VAW public art in a small Ecuadorian city. Visual data is examined and interpreted by way of the social-ecological model (SEM). Specifically, our analysis considers how murals engage with the depiction of (a) VAW, (b) agentic responses to VAW, and (c) the different layers of the SEM. Our analysis identifies four specific strategies for constructing public art messaging to help achieve freedom from VAW.

Ambient Heat and Risk of Serious Hypoglycemia in Older Adults With Diabetes Using Insulin in the U.S. and Taiwan: A Cross-National Case-Crossover Study.

OBJECTIVE: To measure the association between ambient heat and hypoglycemia-related emergency department visit or hospitalization in insulin users. RESEARCH DESIGN AND METHODS: We identified cases of serious hypoglycemia among adults using insulin aged ≥65 in the U.S. (via Medicare Part A/B/D-eligible beneficiaries) and Taiwan (via National Health Insurance Database) from June to September, 2016-2019. We then estimated odds of hypoglycemia by heat index (HI) percentile categories using conditional logistic regression with a time-stratified case-crossover design. RESULTS: Among ∼2 million insulin users in the U.S. (32,461 hypoglycemia case subjects), odds ratios of hypoglycemia for HI >99th, 95-98th, 85-94th, and 75-84th percentiles compared with the 25-74th percentile were 1.38 (95% CI, 1.28-1.48), 1.14 (1.08-1.20), 1.12 (1.08-1.17), and 1.09 (1.04-1.13) respectively. Overall patterns of associations were similar for insulin users in the Taiwan sample (∼283,000 insulin users, 10,162 hypoglycemia case subjects). CONCLUSIONS: In two national samples of older insulin users, higher ambient temperature was associated with increased hypoglycemia risk.

Sample average treatment effect on the treated (SATT) analysis using counterfactual explanation identifies BMT and SARS-CoV-2 vaccination as protective risk factors associated with COVID-19 severity and survival in patients with multiple myeloma.

Patients with multiple myeloma (MM), an age-dependent neoplasm of antibody-producing plasma cells, have compromised immune systems and might be at increased risk for severe COVID-19 outcomes. This study characterizes risk factors associated with clinical indicators of COVID-19 severity and all-cause mortality in myeloma patients utilizing NCATS' National COVID Cohort Collaborative (N3C) database. The N3C consortium is a large, centralized data resource representing the largest multi-center cohort of COVID-19 cases and controls nationwide (>16 million total patients, and >6 million confirmed COVID-19+ cases to date). Our cohort included myeloma patients (both inpatients and outpatients) within the N3C consortium who have been diagnosed with COVID-19 based on positive PCR or antigen tests or ICD-10-CM diagnosis code. The outcomes of interest include all-cause mortality (including discharge to hospice) during the index encounter and clinical indicators of severity (i.e., hospitalization/emergency department/ED visit, use of mechanical ventilation, or extracorporeal membrane oxygenation (ECMO)). Finally, causal inference analysis was performed using the Coarsened Exact Matching (CEM) and Propensity Score Matching (PSM) methods. As of 05/16/2022, the N3C consortium included 1,061,748 cancer patients, out of which 26,064 were MM patients (8,588 were COVID-19 positive). The mean age at COVID-19 diagnosis was 65.89 years, 46.8% were females, and 20.2% were of black race. 4.47% of patients died within 30 days of COVID-19 hospitalization. Overall, the survival probability was 90.7% across the course of the study. Multivariate logistic regression analysis showed histories of pulmonary and renal disease, dexamethasone, proteasome inhibitor/PI, immunomodulatory/IMiD therapies, and severe Charlson Comorbidity Index/CCI were significantly associated with higher risks of severe COVID-19 outcomes. Protective associations were observed with blood-or-marrow transplant/BMT and COVID-19 vaccination. Further, multivariate Cox proportional hazard analysis showed that high and moderate CCI levels, International Staging System (ISS) moderate or severe stage, and PI therapy were associated with worse survival, while BMT and COVID-19 vaccination were associated with lower risk of death. Finally, matched sample average treatment effect on the treated (SATT) confirmed the causal effect of BMT and vaccination status as top protective factors associated with COVID-19 risk among US patients suffering from multiple myeloma. To the best of our knowledge, this is the largest nationwide study on myeloma patients with COVID-19.

CD5 B-Cell Predominant Primary Immunodeficiency: Part of the Spectrum of MAGT1 Deficiency.

Background: Selective anti-polysaccharide antibody deficiency (SPAD) with CD5 B-cell predominance and autoimmune phenomena was identified in a male cohort first reported by Antall et al in 1999. The phenotypically likewise and genotypically identical X-linked immunodeficiency with magnesium defect, Epstein-Barr Virus infection, and neoplasia (XMEN) disease was defined as a novel primary immunodeficiency (PID) in 2011. Recent studies of the magnesium transporter 1 (MAGT1) gene mutation reveal glycosylation defects contributing to more phenotypic variance than the "XMEN" title pathologies. The updated title, "X-linked MAGT1 deficiency with increased susceptibility to EBV-infection and N-linked glycosylation defect," was proposed in 2020. Objectives: To reflect the patient population more accurately, a prospective classification update may consider MAGT1 glycobiological errors contributing to phenotypic variance but also pre-genetic testing era reports with CD5 B-cell predominance. Methods: Patient 1 from Antall et al presented at 28 years of age for further immunological evaluation of his CD5/CD19 B-cell predominance diagnosed at 5 years old. Design: Immune re-evaluation done through flow cytometry and next-generation sequencing. Results: Flow cytometry B-cell phenotyping revealed persistent CD5+CD19+ (93%). Flow cytometric histogram quantified reduced activator CD16+CD56+ natural killer and CD8+ T-cell receptor, Group 2, Member D (NKG2D) glycoprotein expression. A c.923-1_934 deletion loss of function mutation was identified in the MAGT1 gene. Conclusion: We suggest the novel PID XMEN, based on its CD5 B-cell predominance, had been discovered and reported over a decade earlier as CD5+ PID based on the MAGT1 mutation found in the same. We encourage consideration of combining these labels and recent findings to offer the most accurate classification of this disease.

Retrospective cohort study investigating synergism of air pollution and corticosteroid exposure in promoting cardiovascular and thromboembolic events in older adults.

OBJECTIVE: To evaluate the synergistic effects created by fine particulate matter (PM2.5) and corticosteroid use on hospitalisation and mortality in older adults at high risk for cardiovascular thromboembolic events (CTEs). DESIGN AND SETTING: A retrospective cohort study using a US nationwide administrative healthcare claims database. PARTICIPANTS: A 50% random sample of participants with high-risk conditions for CTE from the 2008-2016 Medicare Fee-for-Service population. EXPOSURES: Corticosteroid therapy and seasonal-average PM2.5. MAIN OUTCOME MEASURES: Incidences of myocardial infarction or acute coronary syndrome (MI/ACS), ischaemic stroke or transient ischaemic attack, heart failure (HF), venous thromboembolism, atrial fibrillation and all-cause mortality. We assessed additive interactions between PM2.5 and corticosteroids using estimates of the relative excess risk due to interaction (RERI) obtained using marginal structural models for causal inference. RESULTS: Among the 1 936 786 individuals in the high CTE risk cohort (mean age 76.8, 40.0% male, 87.4% white), the mean PM2.5 exposure level was 8.3±2.4 µg/m3 and 37.7% had at least one prescription for a systemic corticosteroid during follow-up. For all outcomes, we observed increases in risk associated with corticosteroid use and with increasing PM2.5 exposure. PM2.5 demonstrated a non-linear relationship with some outcomes. We also observed evidence of an interaction existing between corticosteroid use and PM2.5 for some CTEs. For an increase in PM2.5 from 8 µg/m3 to 12 µg/m3 (a policy-relevant change), the RERI of corticosteroid use and PM2.5 was significant for HF (15.6%, 95% CI 4.0%, 27.3%). Increasing PM2.5 from 5 µg/m3 to 10 µg/m3 yielded significant RERIs for incidences of HF (32.4; 95% CI 14.9%, 49.9%) and MI/ACSs (29.8%; 95% CI 5.5%, 54.0%). CONCLUSION: PM2.5 and systemic corticosteroid use were independently associated with increases in CTE hospitalisations. We also found evidence of significant additive interactions between the two exposures for HF and MI/ACSs suggesting synergy between these two exposures.

National Trends in Anticoagulation Therapy for COVID-19 Hospitalized Adults in the United States: Analyses of the National COVID Cohort Collaborative.

BACKGROUND: Anticoagulation (AC) utilization patterns and their predictors among hospitalized coronavirus disease 2019 (COVID-19) patients have not been well described. METHODS: Using the National COVID Cohort Collaborative, we conducted a retrospective cohort study (2020-2022) to assess AC use patterns and identify factors associated with therapeutic AC employing modified Poisson regression. RESULTS: Among 162 842 hospitalized COVID-19 patients, 64% received AC and 24% received therapeutic AC. Therapeutic AC use declined from 32% in 2020 to 12% in 2022, especially after December 2021. Therapeutic AC predictors included age (relative risk [RR], 1.02; 95% confidence interval [CI], 1.02-1.02 per year), male (RR, 1.29; 95% CI, 1.27-1.32), non-Hispanic black (RR, 1.16; 95% CI, 1.13-1.18), obesity (RR, 1.48; 95% CI, 1.43-1.52), increased length of stay (RR, 1.01; 95% CI, 1.01-1.01 per day), and invasive ventilation (RR, 1.64; 95% CI, 1.59-1.69). Vaccination (RR, 0.88; 95% CI, 84-.92) and higher Charlson Comorbidity Index (CCI) (RR, 0.98; 95% CI, .97-.98) were associated with lower therapeutic AC. CONCLUSIONS: Overall, two-thirds of hospitalized COVID-19 patients received any AC and a quarter received therapeutic dosing. Therapeutic AC declined after introduction of the Omicron variant. Predictors of therapeutic AC included demographics, obesity, length of stay, invasive ventilation, CCI, and vaccination, suggesting AC decisions driven by clinical factors including COVID-19 severity, bleeding risks, and comorbidities.

'We were having a rather long conversation about the uproar': memorable messages about COVID-19 vaccinations in a mostly young, white sample.

BACKGROUND: Interpersonal communication motivates many decisions related to COVID-19 prevention practices. Previous research shows that the frequency of interpersonal communication is significant. Less is known, however, about who messages interpersonal communication about COVID-19 and what information those messages convey. We sought to understand better these interpersonal communication messages for individuals who are asked to become vaccinated against COVID-19. METHODS: Using a memorable messages approach, we interviewed 149 adults, mostly young, white, college students, about their vaccination choices as they were influenced by messages about vaccination they had received from respected members of their interpersonal networks. Date was analyzed using thematic analysis. RESULTS: Three themes emerged from these interviews of primarily young, white, college students: a dialectic of feeling forced to become vaccinated vs. choice to become vaccinated; a tension between protecting oneself vs. protecting others through vaccination; and, finally, perceptions that family members who were also medical experts were particularly influential. CONCLUSIONS: The dialectic between feelings of choice versus force may require further study into the longer-term impacts of messages that may prompt feelings of reactance and produce undesired outcomes. The dialectic between messages being remembered for their altruism as compared to their selfishness opens opportunities to consider the relative influence of these two impulses. These findings also provide insight into broader topics about countering vaccine hesitancy for other diseases. These findings may not be generalizable to older, more diverse populations.

Air Pollution and Cardiovascular and Thromboembolic Events in Older Adults With High-Risk Conditions.

Little epidemiologic research has focused on pollution-related risks in medically vulnerable or marginalized groups. Using a nationwide 50% random sample of 2008-2016 Medicare Part D-eligible fee-for-service participants in the United States, we identified a cohort with high-risk conditions for cardiovascular and thromboembolic events (CTEs) and linked individuals with seasonal average zip-code-level concentrations of fine particulate matter (particulate matter with an aerodynamic diameter ≤ 2.5 µm (PM2.5)). We assessed the relationship between seasonal PM2.5 exposure and hospitalization for each of 7 CTE-related causes using history-adjusted marginal structural models with adjustment for individual demographic and neighborhood socioeconomic variables, as well as baseline comorbidity, health behaviors, and health-service measures. We examined effect modification across geographically and demographically defined subgroups. The cohort included 1,934,453 individuals with high-risk conditions (mean age = 77 years; 60% female, 87% White). A 1-µg/m3 increase in PM2.5 exposure was significantly associated with increased risk of 6 out of 7 types of CTE hospitalization. Strong increases were observed for transient ischemic attack (hazard ratio (HR) = 1.039, 95% confidence interval (CI): 1.034, 1.044), venous thromboembolism (HR = 1.031, 95% CI: 1.027, 1.035), and heart failure (HR = 1.019, 95% CI: 1.017, 1.020). Asian Americans were found to be particularly susceptible to thromboembolic effects of PM2.5 (venous thromboembolism: HR = 1.063, 95% CI: 1.021, 1.106), while Native Americans were most vulnerable to cerebrovascular effects (transient ischemic attack: HR = 1.093, 95% CI: 1.030, 1.161).

Identifying Barriers and Facilitators for Home Reconstruction for Prevention of Chagas Disease: An Interview Study in Rural Loja Province, Ecuador.

BACKGROUND: Chagas disease (CD) is a tropical parasitic disease spread by triatomine bugs, which are bugs that tend to infest precarious housing in rural and impoverished areas. Reducing exposure to the bugs, and thus the parasite they can carry, is essential to preventing CD in these areas. One promising long-term sustainable solution is to reconstruct precarious houses. Implementing home reconstruction requires an understanding of how householders construct barriers and facilitators they might encounter when considering whether to rebuild their homes. METHODS: To understand barriers and facilitators to home reconstruction, we performed in-depth qualitative interviews with 33 residents of Canton Calvas, Loja, Ecuador, a high-risk endemic region. Thematic analysis was used to identify these barriers and facilitators. RESULTS: The thematic analysis identified three facilitators (project facilitators, social facilitators, and economic facilitators) and two major barriers (low personal economy and extensive deterioration of existing homes). CONCLUSIONS: The study findings provide important loci for assisting community members and for agents of change in home reconstruction projects to prevent CD. Specifically, the project and social facilitators suggest that collective community efforts (minga) are more likely to support home reconstruction intentions than individualist efforts, while the barriers suggest that addressing structural issues of economy and affordability are necessary.

Cardiovascular outcomes with SGLT2 inhibitors versus DPP4 inhibitors and GLP-1 receptor agonists in patients with heart failure with reduced and preserved ejection fraction.

BACKGROUND: No study has compared the cardiovascular outcomes for sodium-glucose cotransporter-2 inhibitors (SGLT2i) head-to-head against other glucose-lowering therapies, including dipeptidyl peptidase 4 inhibitor (DDP4i) or glucagon-like peptide-1 receptor agonist (GLP-1RA)-which also have cardiovascular benefits-in patients with heart failure with reduced (HFrEF) or preserved (HFpEF) ejection fraction. METHODS: Medicare fee-for-service data (2013-2019) were used to create four pair-wise comparison cohorts of type 2 diabetes patients with: (1a) HFrEF initiating SGLT2i versus DPP4i; (1b) HFrEF initiating SGLT2i versus GLP-1RA; (2a) HFpEF initiating SGLT2i versus DPP4i; and (2b) HFpEF initiating SGLT2i versus GLP-1RA. The primary outcomes were (1) hospitalization for heart failure (HHF) and (2) myocardial infarction (MI) or stroke hospitalizations. Adjusted hazards ratios (HR) and 95% CIs were estimated using inverse probability of treatment weighting. RESULTS: Among HFrEF patients, initiation of SGLT2i versus DPP4i (cohort 1a; n = 13,882) was associated with a lower risk of HHF (adjusted Hazard Ratio [HR (95% confidence interval)], 0.67 (0.63, 0.72) and MI or stroke (HR: 0.86 [0.75, 0.99]), and initiation of SGLT2i versus GLP-1RA (cohort 1b; n = 6951) was associated with lower risk of HHF (HR: 0.86 [0.79, 0.93]), but not MI or stroke (HR: 1.02 [0.85, 1.22]). Among HFpEF patients, initiation of SGLT2i versus DPP4i (cohort 2a; n = 17,493) was associated with lower risk of HHF (HR: 0.65 [0.61, 0.69]) but not MI or stroke (HR: 0.90 [0.79, 1.02]), and initiation of SGLT2i versus GLP-1RA (cohort 2b; n = 9053) was associated with lower risk of HHF (0.89 [0.83, 0.96]), but not MI or stroke (HR: 0.97 [0.83, 1.14]). Results were robust across range of secondary outcomes (e.g., all-cause mortality) and sensitivity analyses. CONCLUSIONS: Bias from residual confounding cannot be ruled out. Use of SGLT2i was associated with reduced risk of HHF against DPP4i and GLP-1RA, reduced risk of MI or stroke against DPP4i within the HFrEF subgroup, and comparable risk of MI or stroke against GLP-1RA. Notably, the magnitude of cardiovascular benefit conferred by SGLT2i was similar among patients with HFrEF and HFpEF.

Validity of International Classification of Diseases (ICD)-10 Diagnosis Codes for Identification of Acute Heart Failure Hospitalization and Heart Failure with Reduced Versus Preserved Ejection Fraction in a National Medicare Sample.

BACKGROUND: Heart failure (HF) is a leading cause of hospitalization in older adults. Medicare data have been used to assess HF outcomes. However, the validity of ICD-10 diagnosis codes (used since 2015) to identify acute HF hospitalization or distinguish reduced (heart failure with reduced ejection fraction) versus preserved ejection fraction (HFpEF) is unknown in Medicare data. METHODS: Using Medicare data (2015-2017), we randomly sampled 200 HF hospitalizations with ICD-10 diagnosis codes for HF in the first/second claim position in a 1:1:2 ratio for systolic HF (I50.2), diastolic HF (I50.3), and other HF (I50.X). The primary gold standards included recorded HF diagnosis by a treating physician for HF hospitalization, ejection fraction (EF)≤50 for heart failure with reduced ejection fraction, and EF>50 for HFpEF. If the quantitative EF was not present, then qualitative descriptions of EF were used for heart failure with reduced ejection fraction/HFpEF gold standards. Multiple secondary gold standards were also tested. Gold standard data were extracted from medical records using standardized forms and adjudicated by cardiology fellows/staff. We calculated positive predictive values with 95% CIs. RESULTS: The 200-chart validation sample included 50 systolic, 50 diastolic, 47 combined dysfunction, and 53 unspecified HF patients. The positive predictive values of acute HF hospitalization was 98% [95% CI, 95-100] for first-position ICD-10 HF diagnosis and 66% [95% CI, 58-74] for first/second-position diagnosis. Quantitative EF was available for ≥80% of patients with systolic, diastolic, or combined dysfunction ICD-10 codes. The positive predictive value of systolic HF codes was 90% [95% CI, 82-98] for EFs≤50% and 72% [95% CI, 60-85] for EFs≤40%. The positive predictive value was 92% [95% CI, 85-100] for HFpEF for EFs>50%. The ICD-10 codes for combined or unspecified HF poorly predicted heart failure with reduced ejection fraction or HFpEF. CONCLUSIONS: ICD-10 principal diagnosis identified acute HF hospitalization with a high positive predictive value. Systolic and diastolic ICD-10 diagnoses reliably identified heart failure with reduced ejection fraction and HFpEF when EF 50% was used as the cutoff.

A qualitative exploration of knowledge of Chagas disease among adolescents in rural Ecuador.

INTRODUCTION: Chagas disease (CD) is a neglected tropical disease that affects 6 to 7 million people worldwide. In South America, CD is a major health problem in several regions, causing more than 12 000 deaths per year. CD is caused by a parasite called Trypanosoma cruzi, mostly transmitted through the contaminated feces of certain species of triatomine bug, commonly known as the 'kissing bug'. CD is endemic in Loja province in the southern region of Ecuador, where triatomines have been found in 68% of communities. Previous promotion of healthy practices in Loja province have included educational programs directed toward youth to affirm cultural and social norms that support health and prevent CD transmission. The present study was designed to evaluate current knowledge related to CD among youth in the three communities of Loja province following previous intervention programs. METHODS: A descriptive, qualitative approach was applied using individual semi-structured interviews with 14 young people (eight females, six males) from three rural communities in Loja province. Interviews assessed knowledge about CD transmission, knowledge about the parasite-vector-disease pathway, and the role of youth in preventing Chagas disease in their communities. RESULTS: Following a thematic analysis of the data, the study results showed there is cursory knowledge of the triatomine insect that can carry the causative parasite for CD. Participants were able to generally talk about the vector, habitat and prevention practices for triatomine infestation. Nevertheless, limited understanding of transmission dynamics in the parasite-vector-disease pathway itself was found. One major finding was that prevention practices were not correctly applied or followed, increasing the risk of exposure in the community. Youth also articulated that CD is stigmatized in their communities, which may be a barrier for prevention efforts. CONCLUSION: Gaps in knowledge about the parasite-vector-disease pathway were identified among youth. Overall, youth responses indicated positive regard for prevention practices and a desire to be involved in prevention programs. Developing educational programs focusing on CD transmission may be needed to improve control and prevention of this parasitic disease. The implications of these findings are discussed for developing effective control programs in the region.

Safety, Acceptability, and Initial Effectiveness of a Novel Digital Suicide Prevention Campaign Challenging Perceived Burdensomeness.

Background: Better Off With You is a peer-to-peer, digital suicide prevention campaign pilot designed to challenge the idea of perceived burdensomeness; the schema experienced by many people contemplating suicide that they are a burden on others. Aims: To investigate the safety, acceptability, and initial effectiveness of the campaign. Method: This mixed methods pilot involved a general community sample (N = 157), from targeted sites within two Australian communities. Data were collected at baseline and after 1-week exposure to the campaign videos and website. Qualitative interviews were conducted with a subset of participants (N = 15). Results: Participants rated the campaign as highly engaging and relevant to local communities. In interviews, participants identified the campaign as being unique, safe, and impactful. Overall, exposure to Better Off With You did not result in any notable changes in perceived burdensomeness, psychological distress, or help-seeking. Limitations: The pilot involved a community sample. As such, outcome measurement scores were low at baseline. Conclusion: This pilot provides new insights about the safety, engagement and initial effectiveness of the Better Off With You campaign. Future research is needed to explore its impact on people experiencing suicidal ideation.

Knowledge, attitudes, and practices towards monkeypox during the 2022 outbreak: An online cross-sectional survey among clinicians in Ohio, USA.

BACKGROUND: Controlling monkeypox effectively requires clinicians have knowledge of monkeypox, attitudes supporting of controlling it, and intentions to adopt practices to address it. Little is known, however, about levels of knowledge, attitudes, and practices (KAPs) in clinician populations in Ohio, United States. METHODS: A cross-sectional, internet-based questionnaire assessed knowledge related to monkeypox, attitudes toward ability to control monkeypox and the threat of monkeypox, and prior relevant practices of having received a smallpox vaccine or having knowledge of monkeypox before 2022, intentions to adopt preventive practices, and demographics. Frequency reporting was used to assess overall knowledge and attitudes. Binary logistic regression was used to predict which KAPs were associated with behavioral intentions. RESULTS: A total of 197 clinicians participated. No demographic factor was associated with KAPs. Clinicians had relatively poor levels of knowledge. Participants expressed mixed attitudes about eventual control of monkeypox and about threat posed by monkeypox. About one in four participants reported previous knowledge of monkeypox, and about 40 % had received a smallpox vaccine Clinicians reported insufficient levels of intention to adopt preventive practices. Binary regression analysis suggests only perceptions of the threat of monkeypox to public health were associated with intentions to vaccinate self or others. CONCLUSIONS: Educational interventions with clinicians should address inadequate knowledge to support correct diagnosis and treatment. Efforts to enhance the perception of threat of monkeypox to public health may support adherence to preventive recommendations.

Social support in rural communities in Manabi province, Ecuador.

INTRODUCTION: Social support has been found in many contexts, and in urban Ecuador, to be protective of health, particularly in the context of disaster. Fewer studies have explored the presence and impact of social support in rural Ecuador. This study engages a rural community in Ecuador to examine the general levels of social support, differences in social support based on different demographic groupings and relationships among social support and health outcomes and protective health behaviors. METHODS: A cross-sectional design was used to survey 416 people in a rural Ecuadorian community that had recently experienced an earthquake. Spanish-language versions of the Multidimensional Scale of Perceived Social Support and the Interpersonal Support Evaluation List-12 were applied, as well as questions about demographics and risk reduction behaviors. Body mass index, blood pressure, and cholesterol and blood sugar levels were assessed. Analysis of variance assessed differences in social support among demographic groupings, risk reduction behaviors, and health outcomes. RESULTS: Levels of social support were moderate. Few statistically significant (ie p<0.05) differences in amount of social support received or in sources of social support were found. Men, people 80 years or older, divorced or widowed people, and people living in peripheral areas received less social support than women, people of all other ages, married/cohabitating people, and people living within the village, respectively. Effect sizes of these differences were small. No relationship between social support and health outcomes were found, and few were found for risk reduction factors. CONCLUSION: These findings indicate that social support may function differently in rural Ecuador than in urban contexts. Those promoting social support in rural communities may wish to focus on community-level, not individual-level, interventions. Limitations of applying an assessment of social support from urban Ecuadorian contexts to rural Ecuadorian contexts are discussed.

Communication in Neglected Tropical Diseases' elimination: A scoping review and call for action.

BACKGROUND: Although the practice of communication is often called upon when intervening and involving communities affected by NTDs, the disciplinary framework of health communication research has been largely absent from NTD strategies. To illustrate how practices conceptualized and developed within the communication field have been applied in the context of NTD elimination, we conducted a scoping review focusing on two diseases currently targeted for elimination by the WHO: lymphatic filariasis and Chagas disease. METHODS: We examined studies published between 2012 and 2020 in five electronic databases. Selected articles were required to (i) have explicit references to communication in either the abstract, title, or key words; (ii) further elaborate on the search terms (communication, message, media, participation and health education) in the body of the article; and (iii) sufficiently describe communication actions associated to those terms. Using the C-Change Socio-Ecological Model for Social and Behavior Change Communication as a reference, the articles were analysed to identify communication activities, theoretical frameworks, and/or rationales involved in their design, as well as their intended level of influence (individual, interpersonal, community, or enabling environment). RESULTS AND IMPLICATIONS: A total of 43 articles were analysed. Most interventions conceptualized communication as a set of support tools or supplemental activities delivering information and amplifying pre-defined messages aimed at increasing knowledge, encouraging community involvement, promoting individual behavior change, or securing some degree of acceptability of proposed strategies. Although important attempts at further exploring communication capabilities were identified, particularly in participation-based strategies, for most studies, communication consisted of an underdeveloped and under-theorized approach. We contend that a more complex understanding of the capacities offered by the health communication field could help attain the biomedical and social justice goals proposed in NTD elimination strategies. Three ways in which the field of health communication could further enhance NTD efforts are presented: informing interventions with theory-based frameworks, exploring the political complexity of community participation in specific contexts, and identifying conceptualizations of culture implied in interventions' design. CONCLUSION: This article is a call to action to consider the resources offered by the health communication field when researching, designing, or implementing NTD interventions.
