Poverty Traps and Mortality From Liver Diseases in the United States.

INTRODUCTION: Poverty traps, locations with multigenerational poverty, result from structural and economic factors that can affect health of residents within these locations. The aim of this study was to define poverty traps within the contiguous United States and their impact on outcomes from liver diseases or cancers. METHODS: A systematic census-tract level analysis was used to spatially define regions that encompassed poverty traps. Clusters of prevalent poverty and mortality from chronic liver diseases or liver cancers were identified. Temporal trends and the relationship between race and ethnicity, type of space and escape from poverty traps on disease mortality within hot spots were determined. RESULTS: The proportion of census tracts enduring multigenerational poverty within counties was strongly associated with mortality from liver disease or cancer. There was a highly significant clustering of persistent poverty and increased mortality. Hot spots of high-mortality areas correlated with factors related to income, ethnicity, and access to health care. Location or noneconomic individual factors such as race and ethnicity were important determinants of disparities within hot spots. Distinct groups of poverty traps were defined. The highly characteristic demographics and disease outcomes within each of these groups underscored the need for location-specific interventions. DISCUSSION: Poverty traps are a major and important spatially determined risk factor for mortality from liver diseases and cancers. Targeted location-specific interventions and economic development aimed at addressing the underlying causes of poverty and enhancing prosperity will be required to reduce mortality from liver diseases within poverty traps.

Structure and Funding of Clinical Informatics Fellowships: A National Survey of Program Directors.

BACKGROUND: In 2011, the American Board of Medical Specialties established clinical informatics (CI) as a subspecialty in medicine, jointly administered by the American Board of Pathology and the American Board of Preventive Medicine. Subsequently, many institutions created CI fellowship training programs to meet the growing need for informaticists. Although many programs share similar features, there is considerable variation in program funding and administrative structures. OBJECTIVES: The aim of our study was to characterize CI fellowship program features, including governance structures, funding sources, and expenses. METHODS: We created a cross-sectional online REDCap survey with 44 items requesting information on program administration, fellows, administrative support, funding sources, and expenses. We surveyed program directors of programs accredited by the Accreditation Council for Graduate Medical Education between 2014 and 2021. RESULTS: We invited 54 program directors, of which 41 (76%) completed the survey. The average administrative support received was $27,732/year. Most programs (85.4%) were accredited to have two or more fellows per year. Programs were administratively housed under six departments: Internal Medicine (17; 41.5%), Pediatrics (7; 17.1%), Pathology (6; 14.6%), Family Medicine (6; 14.6%), Emergency Medicine (4; 9.8%), and Anesthesiology (1; 2.4%). Funding sources for CI fellowship program directors included: hospital or health systems (28.3%), clinical departments (28.3%), graduate medical education office (13.2%), biomedical informatics department (9.4%), hospital information technology (9.4%), research and grants (7.5%), and other sources (3.8%) that included philanthropy and external entities. CONCLUSION: CI fellowships have been established in leading academic and community health care systems across the country. Due to their unique training requirements, these programs require significant resources for education, administration, and recruitment. There continues to be considerable heterogeneity in funding models between programs. Our survey findings reinforce the need for reformed federal funding models for informatics practice and training.

Vermistabilization of mango tree pruning waste with five earthworm species: A biochemical and heavy metal assessment.

Mango tree pruning results in high biomass output, which is a serious agricultural and environmental problem. Vermicomposting is a potential, fast and sustainable tool to address these challenges. For sixty days, the experiment was carried out in six vermireactors containing five earthworm species by Eudrilus eugeniae, Eisenia fetida, Aporrectodea rosea, Lumbricus rubellus, and Lampito mauritii, as well as composting (without earthworm) using mango tree pruning waste biomass along with cattle dung as an instant preferred feeding material for earthworms. The pH, TOC, C/N and C/P ratios of the waste were substantially reduced by the earthworm activity. However, after vermicomposting, the levels of macronutrients (N, P, K, Ca, Mg, S) and micronutrients (Fe, Mn, Zn, and Cu) and microbial count substantially increased. The TOC content of waste was reduced by 42-55%, and the C/N of vermicompost ranged from 5.58 to 11.38. The results showed that earthworm fecundity was highest in vermireactors containing Eudrilus eugeniae and Eisenia fetida. The current study was ultimately determine that vermicomposting using Eudrilus eugeniae or Eisenia fetida is an effective strategy for utilising mango tree pruning waste, ensuring environmental sustainability and improving farmer revenue.

Utility of an Artificial Intelligence Enabled Electrocardiogram for Risk Assessment in Liver Transplant Candidates.

BACKGROUND: Post-operative cardiac complications occur infrequently but contribute to mortality after liver transplantation (LT). Artificial intelligence-based algorithms based on electrocardiogram (AI-ECG) are attractive for use during pre-operative evaluation to screen for risk of post-operative cardiac complications, but their use for this purpose is unknown. AIMS: The aim of this study was to evaluate the performance of an AI-ECG algorithm in predicting cardiac factors such as asymptomatic left ventricular systolic dysfunction or potential for developing post-operative atrial fibrillation (AF) in cohorts of patients with end-stage liver disease either undergoing evaluation for transplant or receiving a liver transplant. METHODS: A retrospective study was performed in two consecutive adult cohorts of patients who were either evaluated for LT or underwent LT at a single center between 2017 and 2019. ECG were analyzed using an AI-ECG trained to recognize patterns from a standard 12-lead ECG which could identify the presence of left ventricular systolic dysfunction (LVEF < 50%) or subsequent atrial fibrillation. RESULTS: The performance of AI-ECG in patients undergoing LT evaluation is similar to that in a general population but was lower in the presence of prolonged QTc. AI-ECG analysis on ECG in sinus rhythm had an AUROC of 0.69 for prediction of de novo post-transplant AF. Although post-transplant cardiac dysfunction occurred in only 2.3% of patients in the study cohorts, AI-ECG had an AUROC of 0.69 for prediction of subsequent low left ventricular ejection fraction. CONCLUSIONS: A positive screen for low EF or AF on AI-ECG can alert to risk of post-operative cardiac dysfunction or predict new onset atrial fibrillation after LT. The use of an AI-ECG can be a useful adjunct in persons undergoing transplant evaluation that can be readily implemented in clinical practice.

Use of a National Clinical Skills Assessment Program Improves the Clinical Competency for Correctional Nurses and Advanced Practice Providers.

The Federal Bureau of Prisons clinical skills training development (CSTD) team accomplished the planning, creation, and execution of a first-ever national clinical skills assessment program (CSAP) for nurses and advanced practice providers (APPs). Clinical skills assessment is a part of nurse and APP credentialing and privileging and must be completed for new hires along with continued biennial recredentialing accreditation standards. A training resource manual, discipline-specific skills checklist, pre-/postprogram written examination, and standard operating procedures were created. The CSTD team used commercially available manikins, food items, and easily obtainable office supplies for simulated experiential skills assessments. The CSAP provided a consistent, reproducible, and scalable approach for the orientation, assessment, and, if indicated, remediation for correctional nurses and APPs.

Trends in Ambulatory Surgery Center Utilization for Otolaryngologic Procedures among Medicare Beneficiaries, 2010-2017.

OBJECTIVE: Surgical care is increasingly shifting to freestanding ambulatory surgical centers (ASCs). The extent to which otolaryngologists use ASCs has implications for patient safety and health care spending. This study characterizes trends in utilization and resultant financial implications for common otolaryngologic procedures performed at ASC and hospital outpatient departments (HOPDs). STUDY DESIGN: Retrospective cross-sectional analysis. SETTING: ASCs, HOPDs. SUBJECTS AND METHODS: Subjects included Medicare beneficiaries undergoing outpatient otolaryngologic procedures between 2010 and 2017. Procedures included the 20 highest-volume procedures performed by otolaryngologists at ASCs in 2017. Main outcomes included absolute and relative percentage difference in the proportion of procedures furnished at ASCs and HOPDs and estimated Medicare cost savings resulting from increased ASC utilization between 2011 and 2017. RESULTS: The proportion of outpatient otolaryngologic procedures performed at ASCs increased by 1.8% (relative difference: 10.0%; mean annual relative increase: 1.60%), and the proportion located at HOPDs decreased by 6.0% (relative difference: -11.8%; mean annual relative decrease: -1.6%) between 2010 and 2017. Rhinoplasty accounted for the largest absolute increase in ASC utilization over the study period (absolute [relative] 8.9% [33.5%]). Increased ASC utilization resulted in an estimated $7.1 million in cost savings to Medicare between 2011 and 2017. CONCLUSION: Otolaryngologists shifted outpatient surgical care from HOPDs to ASCs between 2010 and 2017, with resultant reductions in Medicare expenditures. Further research is necessary to examine the impact of this shift on patient safety.

Independent and Joint Use of Statins and Metformin by Elderly Patients With Diabetes and Overall Survival Following HCC Diagnosis.

GOAL: To investigate associations of prediagnosis and postdiagnosis use of statins and metformin on overall survival of patients with diabetes who later developed HCC. BACKGROUND: Statins and metformin have received considerable interest as potential chemopreventive agents against hepatocellular carcinoma (HCC) development in individuals with type 2 diabetes mellitus (T2DM); however, their impact on overall survival of patients with T2DM who later develop HCC (diabetic HCC patients) is unclear. STUDY: Data on 2499 elderly diabetic HCC patients obtained from the SEER-Medicare program (2009 to 2013) were analyzed. Patients were categorized based on use of statins only, metformin only, both, or neither (reference for all comparisons). The patients were further categorized based on: (1) metformin dose: ≤1500 or >1500 mg/d; (2) statins functional form: hydrophilic (pravastatin and rosuvastatin) or lipophilic (atorvastatin, fluvastatin, lovastatin, and simvastatin); (3) statins potency: high (atorvastatin, rosuvastatin, and simvastatin) or low (fluvastatin, lovastatin, and pravastatin); and (4) individual statins type. Multivariable-adjusted hazard ratios (HR) and 95% confidence intervals (CIs) were calculated using Cox proportional hazard models. RESULTS: Prediagnosis use of metformin dose ≤1500 mg/d was associated with lower risk of death after HCC diagnosis in patients with T2DM (HR, 0.72; 95% CI, 0.58-0.91), adjusting for postdiagnosis metformin dose, diabetes severity, Charlson comorbidity index, tumor characteristics, and other relevant factors. No association was found for prediagnosis metformin dose >1500 mg/d or postdiagnosis metformin use. Further, no association was found for either prediagnosis or postdiagnosis statins use. CONCLUSIONS: Prediagnosis use of metformin dose ≤1500 mg/d is associated with longer overall survival of elderly diabetic HCC patients.

Risk of De Novo Hepatocellular Carcinoma Following Use of Direct Acting Antiviral Medications for Treatment of Chronic Hepatitis C.

Direct-acting antivirals (DAA) are now the mainstay of treatment for patients with chronic hepatitis C virus (HCV); however, there is some controversy over whether use of DAAs for HCV, as compared with IFN-based regimens, leads to an increased risk for hepatocellular carcinoma (HCC) development. We investigated the association between use of DAAs and subsequent development of HCC in longitudinal data from patients with HCV from diverse backgrounds (various ages, ethnicities, and geographic regions) across the United States. The design was a retrospective study performed using medical and pharmacy claims from OptumLabs. HCV treatment exposure was categorized as DAA-only, DAA + IFN, any-DAA, or IFN-only. To account for confounding by indication, inverse probability of treatment weighting was performed. Cox proportional hazard models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI). We identified 5,781 patients with HCV with no history of HCC at baseline. Compared with IFN-only regimen, no significant increase in HCC risk was found for use of DAA-only (HR, 1.53; 95% CI, 0.73-3.23), DAA + IFN (HR, 1.02; 95% CI, 0.51-2.06), or any-DAA (HR, 1.04; 95% CI, 0.65-1.65). When stratified by sustained virological response (SVR), we noted a higher HCC risk for DAA-only among patients who achieved SVR post-treatment (HR, 7.53; 95% CI, 1.48-38.34), but the CIs were wide, which might be due to the small sample size of the subgroups. Among those who did not achieve SVR, no association was found for use of DAA-only (HR, 0.59; 95% CI, 0.19-1.91). These findings do not provide compelling evidence for the conception that use of DAAs for HCV is associated with increased risk of HCC development.

Racial, Ethnic, and Age Disparities in Incidence and Survival of Intrahepatic Cholangiocarcinoma in the United States; 1995-2014.

INTRODUCTION AND AIM: Despite reports of increased incidence of intrahepatic cholangiocarcinoma (iCCA) in the United States, the impact of age or influences of race and ethnicity are not clear. Disparities in iCCA outcomes across various population subgroups also are not readily recognized due to the rarity of this cancer. We examined ethnic, race, age, and gender variations in iCCA incidence and survival using data from the Surveillance, Epidemiology, and End Results Program (1995-2014). MATERIAL AND METHODS: We assessed age-adjusted incidence rates, average annual percentage change in incidence, and hazard ratios (HRs) with 95% confidence intervals (CIs) for all-cause and iCCA-specific mortality. RESULTS: Overall, 11,127 cases of iCCA were identified, with an age-adjusted incidence rate of 0.92 per 100,000. The incidence rate increased twofold, from 0.49 per 100,000 in 1995 to 1.49 per 100,000 in 2014, with an average annual rate of increase of 5.49%. The iCCA incidence rate was higher among persons age 45 years or older than those younger than 45 years (1.71 vs. 0.07 per 100,000), among males than females (0.97 vs. 0.88 per 100,000) and among Hispanics than non-Hispanics (1.18 vs. 0.89 per 100,000). Compared to non-Hispanics, Hispanics had poorer 5-year allcause mortality (HR = 1.11, 95%CI: 1.05-1.19) and poorer iCCA-specific mortality (HR = 1.15, 95%CI: 1.07-1.24). Survival rates were poor also for individuals age 45 years or older, men, and Blacks and American Indians/Alaska Natives. CONCLUSION: The results demonstrate ethnic, race, age and gender disparities in iCCA incidence and survival, and confirm continued increase in iCCA incidence in the United States.

Assessment of response to therapy in hepatocellular carcinoma.

The appropriate use of conventional or potential treatments for hepatocellular carcinoma requires that benefit can be shown. Therefore, the accurate assessment of response is both critical and essential. Demonstration of benefit observed will be determined by the criteria used. However, the use of conventional criteria based on anatomical imaging to assess response and progression is inadequate. Limitations occur due to the unique nature, presentation, and course of hepatocellular cancer, any underlying concomitant disease, the multiplicity of treatment options, and the challenges in assessing viable tumor. Locoregional therapies or cytostatic therapies can have beneficial effects and induce tumor necrosis without appreciable changes in tumor size. In recognition of the inherent limitations in conventional imaging criteria, various modifications have been proposed. In this review, the goals of assessing tumor response in clinical practice and in clinical trials are outlined. The varying patterns of response to different therapeutic modalities such as locoregional therapy and molecularly targeted therapy are reviewed, and an approach to the assessment of response based on clinical, biochemical, morphological, and functional criteria has been outlined. The implications of current and proposed approaches of assessing response for clinical practice or design of clinical trials are reviewed.

Direct costs of hospitalization for rotavirus gastroenteritis in different health facilities in India.

BACKGROUND & OBJECTIVES: Diarrhoeal disease is the fifth leading cause of all mortality globally. To this burden, rotavirus contributes over half a million deaths annually. This pilot study was conducted to determine the economic burden of diarrhoeal episodes on families from different geographical regions accessing medical facilities in India. METHODS: Participants were enrolled from four study sites with eight reporting hospitals, categorized as non-profit and low cost, private and government facilities between November 2008 and February 2009. Questionnaires detailing healthcare utilization, medical and non-medical expenditure and lost income were completed by families of children < 5 yr of age hospitalized for gastroenteritis. All available faecal samples were tested for rotavirus. RESULTS: A total of 211 patients were enrolled. The mean total cost of a hospitalized diarrhoeal episode was ` 3633 (US$ 66.05) for all facilities, with a marked difference in direct costs between governmental and non-governmental facilities. Costs for rotavirus positive hospitalizations were slightly lower, at ` 2956 (US$ 53.75). The median cost of a diarrhoeal episode based on annual household expenditure was 6.4 per cent for all-cause diarrhoea and 7.6 per cent for rotavirus diarrhoea. Of the 124 samples collected, 66 (53%) were positive for rotavirus. INTERPRETATION & CONCLUSIONS: Data on direct costs alone from multiple facilities show that diarrhoeal disease constitutes a large economic burden on Indian families. Affordable, effective vaccines would greatly reduce the economic burden of severe gastroenteritis on patients, families and the government.

Identifying opportunities for improved colorectal cancer screening in primary care.

BACKGROUND: Although current recommendations advocate screening persons 50 years of age or older for colorectal cancer (CRC), actual screening practice is highly variable among primary care physicians (PCPs). Knowledge of the factors that influence whether or not screening is offered during a clinic visit is essential to develop effective screening strategies. METHODS: A cross-sectional telephone survey of one in four randomly selected patients aged 50 years or older (n = 400) attending a primary care clinic within an integrated health care system in central Texas was conducted. A survey of all PCPs (n = 32) at the practice sites was also administered. RESULTS: The visit type was an important determinant of whether CRC screening was discussed, with most discussion occurring during visits for physicals (P < 0.0001). This finding was corroborated by the physician survey. Patient age and education were also associated with a higher likelihood of having been offered CRC screening (P = 0.009 and 0.014, respectively). Patient race, gender, primary language, PCP, or clinics attended were not significantly associated with the discussion of CRC screening. CONCLUSIONS: Discussions regarding CRC screening are most likely to occur during preventive care visits. Thus, facilitating preventive visits especially for the elderly represents an opportunity to improve CRC screening rates in primary care practice.
