Summary: Childhood obesity is of great importance given a third of children in the USA are overweight or obese. Previous research has examined neighbourhood economic context in relation to children's obesity and obesity‐rated behaviours. However, different definitions and measures of neighbourhood context make it difficult to compare findings and make definitive conclusions. This review is to synthesize studies assessing the associations between neighbourhood economic context and children's obesity or obesity‐related behaviours. The review included 39 studies investigating the relationship between residential neighbourhood economic context and children's obesity, dietary habits or physical activity after controlling for family‐level economic status. Studies reported mixed results in the relationship between neighbourhood economic indicators and child obesity outcomes. Of reviewed studies, 60% showed an inverse association between higher neighbourhood economic status and obesity, and 33% and 14% showed positive associations between higher neighbourhood economic status and healthy dietary habits or physical activity. Several studies suggested gender, age, race/ethnicity, individual‐level economic status, rurality and social connectedness as moderators in the neighbourhood‐obesity association. Findings suggest that, in order to move towards causal inferences and inform interventions, future research should examine neighbourhood impacts longitudinally and test theory‐driven mediators and moderators to clarify the mechanisms by which neighbourhoods influence child obesity.

Background Ongoing development and expansion of trauma centers in the United States necessitates empirical analysis of the effect of investment in such resources on population-level health outcomes. Methods Multiple linear regressions were performed to predict state-level trauma-related mortality among adults and the elderly across 50 US states in 2010. The number of trauma centers per capita in each state and the percentage of each state's population living within 45-min of a trauma center served as the key independent variables and injury-related mortality served as the dependent variable. All analyses were stratified by age (adult versus elderly; elderly ≥ 65 years old) and were performed in SPSS. Results The proportion of a population with geographic proximity to a trauma center demonstrates a consistent inverse linear relationship to injury-related mortality. The relationship reliably retains its significance in models including demographic covariates. Interestingly, access to Levels I and II trauma centers demonstrates a stronger correlation with mortality than was observed with Level III centers. Conclusion Trauma center access is associated with reduced trauma-related mortality among both adults and the elderly as measured by state reported mortality rates. Ongoing efforts to designate and verify new trauma centers, particularly in poorly-served 'trauma deserts', could lead to lower mortality for large populations. [ABSTRACT FROM AUTHOR]

To investigate the risk factors for acute GVHD (aGVHD), based on NIH consensus criteria (NCC), we evaluated 775 patients who underwent allogeneic transplantation. Of them, 346 patients developed aGVHD by NCC, in whom we also analyzed factors affecting aGVHD-specific survival. The cumulative incidence of aGVHD was 44.7%, consisting of classic aGVHD (n=320) and late-onset (n=26). Multivariate analyses revealed that younger age (P=0.015), unrelated donors (P=0.004) and acute leukemia compared with other hematologic malignancies (P=0.005) were significant risk factors for aGVHD, whereas PBSCs showed no association (P=0.720). Multivariate analyses, with only aGVHD patients, revealed that late-onset aGVHD had superior aGVHD-specific survival to classic aGVHD (P=0.044), and identified the association of visceral organ involvement (P=0.002), severity of aGVHD at onset (P=0.035) and advanced disease status (P<0.001) with inferior aGVHD-specific survival. In conclusion, this study demonstrates the risk and prognostic factors for aGVHD by NCC with some differences with the previous reports that were based on old criteria. The difference in the risk factors according to different criteria will give insights about the pathophysiology of GVHD. The better prognosis of late-onset aGVHD than of classic aGVHD raises the necessity for prospective trials with a large cohort focusing on the onset time. [ABSTRACT FROM AUTHOR]

According to the United States census report, the Hispanic population is the number one minority and ethnic group in the United States. Risk factors most commonly associated with the substance-abusing Hispanic population are related to community, family, school, and individual/peer influences. The bulk of research concerning substance abuse risk factors among the Hispanic population focused on the Hispanic population in Texas, Arizona, New York, California, and Florida. There is limited information discussed about Hispanics and substance use/abuse in North Carolina. This limitation may pose threats to the effectiveness of model programs being replicated and generalizability due to differences in culture. Research is needed in the study of Hispanic substance use/abuse in rural areas of the country. [ABSTRACT FROM AUTHOR]

Modelling the performance of asphalt concrete using continuum damage theories is an approach that has gained international attention in recent years. These types of models are advantageous because they ignore many of the complicated physical interactions at the microscale level and instead characterise a material using macroscale observations. One such model, the viscoelastic continuum damage model, is used in this study to examine the fatigue performance of asphalt concrete mixtures. A mathematically rigorous exploration is undertaken to specialise the model for easy prediction and characterisation using cyclic fatigue tests on cylindrical specimens. This process reveals that certain theoretical shortcomings are evident in other similar models and corrects them with a newly developed model. The resulting model is capable of capturing the underlying material property, i.e. the damage characteristic curve, which is responsible for the performance of controlled stress, controlled crosshead strain and constant crosshead rate monotonic tension until failure tests.

Absolute bang time measurements with the gas Cherenkov detector (GCD) and gamma reaction history (GRH) diagnostic have been performed to high precision at the OMEGA laser facility at the University of Rochester with bang time values for the two diagnostics agreeing to within 5 ps on average. X-ray timing measurements of laser-target coupling were used to calibrate a facility-generated laser timing fiducial with rms spreads in the measured coupling times of 9 ps for both GCD and GRH. Increased fusion yields at the National Ignition Facility (NIF) will allow for improved measurement precision with the GRH easily exceeding NIF system design requirements. [ABSTRACT FROM AUTHOR]

The purpose of this article is to understand dementia caregiving and postcaregiving experience from the Korean-American family caregiver perspective. In this transcendental phenomenological study, I analyzed both in-depth interviews from 8 caregivers and field notes with the procedure of Moustakas' (1994) modification of the Van Kaam method. Five core themes characterized participants' experiences: understanding elderly patients with Alzheimer's by accepting it as a disease; self-defining and self-appraising of caregivers; caregiving as a family affair while examining transgenerational continuity of filial piety; returning caregiving to caregivers in turn as a mode of mourning; and reviewing dissatisfying experiences with the formal care system. Based on a small but relatively heterogeneous sample, this study advances the understanding of the underlying, dynamic context of Korean-American family dementia caregiving and addresses certain implications of geriatric social work intervention for postcaregivers.

Background. Noroviruses are enterically transmitted and are a frequent cause of gastroenteritis, affecting 23 million people annually in the United States. We describe a norovirus outbreak and its control in a tertiary care hospital during February-May 2004. Methods. Patients and health care workers met the case definition if they had new onset of vomiting and/or diarrhea during the outbreak period. Selected stool samples were tested for norovirus RNA. We also determined outbreak costs, including the estimated lost revenue associated with unit closures, sick leave, and cleaning expenses. Results. We identified 355 cases that affected 90 patients and 265 health care workers and that were clustered in the coronary care unit and psychiatry units. Attack rates were 5.3% (7 of 133) for patients and 29.9% (29 of 97) for health care workers in the coronary care unit and 16.7% (39 of 233) for patients and 38.0% (76 of 200) for health care workers in the psychiatry units. Thirteen affected health care workers (4.9%) required emergency department visits or hospitalization. Detected noroviruses had 98%-99% sequence identity with representatives of a new genogroup 11.4 variant that emerged during 2002-2004 in the United States (e.g., Farmington Hills and other strains) and Europe. Aggressive infection-control measures, including closure of units and thorough disinfection using sodium hypochlorite, were required to terminate the outbreak. Costs associated with this outbreak were estimated to be $657,644. Conclusions. The significant disruption of patient care and cost of this single nosocomial outbreak support aggressive efforts to prevent transmission of noroviruses in health care settings.

Stool specimens from 156 Maryland nursing home residents, who became ill during 20 out-breaks of gastroenteritis from November 1987 through February 1988, were analyzed. All tested negative for astroviruses, enteroviruses, Group A rotaviruses, Sapporo-like caliciviruses, and enteric bacteria (i.e., Salmonella, Clostridium, and Shigella species). Eighty-two (52%) were positive for Norwalk-like viruses (NLVs), members of the family Caliciviridae. Six distinct genetic clusters within genogroups I and II of the NLVs were detected; a genogroup II (GII) virus closely related to the Camberwell virus in the NLV GII/4 genetic cluster was the predom-inant strain. Serologic evidence of infection with >1 NLV was detected in 61 (56%) of 109 patients tested against 3 NLV antigens (i.e., Norwalk, Hawaii, and Toronto viruses). Sixteen (80%) outbreaks met the definition for an NLV outbreak. Taken together with a retrospective analysis of bacterial gastroenteritis in this same setting, these data support a major role for NLVs as etiologic agents of gastroenteritis in elderly persons.

SummaryField populations of face flies, Musca autumnalis DeGeer (Diptera: Muscidae) were sampled serially in the late summers and autumns of 1985–96, in order to measure the dynamics of diapause development in Iowa, U.S.A. Fat body hypertrophy and ovarian development were assessed through dissection, and pteridine quantities in the fly heads were measured spectrofluorometrically to estimate their physiological and chronological ages. Published laboratory studies of diapause induction established the expectation that diapause incidence would vary over successive years with prevailing temperatures. The expectation was not met by field data. Patterns in the frequencies of hypertrophied fat body and of vitellogenic nullipars indicated that about 50% of recruited adults began developing into diapause in the second week of September in each year. Degree-day summations for each year from 1985 to 1996 suggested that the hypothetical mean optimal time for switching into diapause would be in the second week of September, because a rapidly diminishing proportion of eggs laid later would result in viable, overwintering flies. It was concluded that face flies do not use daily temperatures in late summer, but instead cue on photoperiod for diapause. [ABSTRACT FROM AUTHOR]

This article disaggregates change in adolescent fertility between 1971 and 1979 into four components: change in marriage patterns, in nonmarital sex, in pregnancy, and in birth. It also assesses quantitatively the relative contribution of each component to the change over time in two fertility outcomes: the probability of a nonmarital live birth and, given a live birth, the odds of its being nonmarital. The changes in the probability of sexual debut prior to marriage and in marriage patterns themselves are the two most important contributors to these changes. The influence on the change in adolescent fertility outcomes of the decreased likelihood of marriage following a nonmarital pregnancy was compensated for by the increased use of abortion to terminate the pregnancy.

This paper compares the results from a GEANT4 simulation of the gas Cherenkov detector 1 (GCD1) with previous simulations and experimental data from the Omega laser facility. The GCD1 collects gammas emitted during a deuterium-tritium capsule implosion and converts them, through several processes, to Cherenkov light. Photon signals are recorded using subnanosecond photomultiplier tubes, producing burn reaction histories. The GEANT4 GCD1 simulation is first benchmarked against ACCEPT, an integrated tiger series code, with good agreement. The simulation is subsequently compared with data from the Omega laser facility, where experiments have been performed to measure the effects of Hohlraum materials on reaction history signals, in preparation for experiments at the National Ignition Facility.

Introduction: Non-alcoholic steatohepatitis (NASH) may progress to more advanced liver disease. This study aimed to characterize NASH progression and mortality in the Medicare population., Methods: Patients with NASH in 100% Medicare fee-for-service claims accrued from 2015-2021 who were ≥ 66 years old at index diagnosis, continuously enrolled for ≥ 12 months prior to and ≥ 6 months following index (unless death), and had no evidence of other causes of liver disease were included. Diagnosis codes defined severity states: non-cirrhotic NASH, compensated cirrhosis (CC), decompensated cirrhosis (DCC), hepatocellular carcinoma (HCC), and liver transplant (LT). Survival analyses of disease progression and mortality were conducted for each state and by year of progression (Y1-5). Cox proportional hazards models assessed risk factors of worsening disease., Results: Mean age and follow-up were 72.2 and 2.8 years in 14,806 unique patients (n = 12,990 NASH; 1899 CC; 997 DCC; 209 HCC; 140 LT). Progression rates were highest for patients with CC (11-37% for Y1-5), followed by DCC (3-18%), NASH (3-12%), and HCC (2-4%). Mortality rates were highest for patients with HCC (41-85% for Y1-5), followed by DCC (41-76%), LT (7-33%), CC (6-26%), and NASH (2-12%). Patients with any disease progression had a 5-year mortality rate more than double that of patients without progression (41% vs. 16%). Delayed progression from NASH was associated with lower mortality risk; the 5-year mortality rate was 26% lower for patients with progression in Y2 vs. Y1 (32% vs. 43%) and further decreased for progression in Y3-Y5. Risk factors included age, nursing home use, congestive heart failure, coagulopathy, fluid/electrolyte disorders, and unexplained weight loss., Conclusion: Medicare patients ≥ 66 years with NASH experience high risk of disease progression associated with increased mortality rates. Slower disease progression is associated with lower mortality rates, suggesting that therapies that can delay or prevent NASH progression may reduce morbidity and mortality., (© 2024.

Introduction: As of March 2024, resmetirom is the first and only therapy approved in the United States (US) for the treatment of adults with non-cirrhotic nonalcoholic steatohepatitis (NASH) with moderate-to-advanced liver fibrosis (MALF) consistent with stages F2/F3 fibrosis. Estimates of the diagnosed, treatment-eligible NASH population are poorly understood due to diagnostic variability. This study provides a contemporary estimate of the size of the US resmetirom treatment-eligible population., Methods: A dynamic population calculator was developed combining literature, screening guidelines, resmetirom study criteria, and analyses of the NHANES 2017-March 2020 cycle. It computes NASH prevalence, proportion non-cirrhotic NASH with MALF, Year 1 diagnosis, and new diagnoses in Years 2 and 3. NASH prevalence was estimated by applying the American Association of Clinical Endocrinology screening algorithm and recommended NIT cut-offs in the NHANES dataset. The proportion of non-cirrhotic NASH with MALF was informed by analyses of the Forian US integrated medical claims database using NASH and cirrhosis-specific ICD-10-CM codes and FIB-4 scores. NASH diagnosis rates were obtained from published estimates and NHANES responses. Treatment-eligible population growth was projected using published incidence data. Estimates were compared to a NASH budget-impact-analysis (BIA) from the Institute for Clinical and Economic Review (ICER)., Results: In the base case, a NASH prevalence of 4.6% was modeled (range 1.3-14.2%). This value was multiplied by the proportion estimated to have non-cirrhotic MALF (i.e., 35%). Published analyses suggest a diagnosis rate of ~ 10% (range 3.3-14.3%) and ~ 16% year-over-year growth in the treatment-eligible population. Assuming a 1-million commercial-member population, the resmetirom treatment-eligible population was estimated as 1255-1699 in Years 1-3 following approval. Sensitivity analyses were conducted and comparison to the ICER BIA was influenced by different diagnosis rates., Conclusion: Estimation of the treatment-eligible population for resmetirom depends importantly on NASH diagnosis rates, which are predicted to be < 15% in the 3 years after drug approval. Nonalcoholic steatohepatitis (NASH) is an advanced form of nonalcoholic fatty liver disease. Previously there were no treatments for NASH in the United States (US), but as of March 2024, the US Food and Drug Administration (FDA) approved resmetirom (REZDIFFRA™), a once-daily, oral therapy, in conjunction with diet and exercise, under accelerated approval for the treatment of adults (aged 18 years or older) with non-cirrhotic NASH with moderate-to-advanced liver fibrosis (MALF), consistent with stages F2-F3. It is not well understood how many diagnosed patients with NASH would be eligible for treatment with resmetirom; thus, this study aimed to estimate the size of the US resmetirom treatment-eligible population. To do so, we created a flexible population calculator that considers how many people have NASH, what proportion would be eligible for resmetirom treatment-i.e., have non-cirrhotic NASH with MALF-and of those how many people would be diagnosed. We used published literature, screening guidelines, resmetirom study criteria, and analyses of national surveys to inform our range of estimates. In the main analysis, we modeled a NASH prevalence of 4.6% (range 1.3-14.2%), which was then limited to the proportion estimated to have non-cirrhotic NASH with MALF (i.e., 35%) and diagnosed (i.e., 10%, range 3.3-14.3%). A year-over-year growth of approximately 16% in the treatment-eligible population was modeled in years following approval. Assuming a population of 1 million commercial insurance enrollees, the resmetirom treatment-eligible population was estimated to be 1255-1699 in Years 1-3 following approval. We assessed alternative scenarios and have compared our results to existing models., (© 2024. The Author(s).)

Periodontitis is associated with elevated C-reactive protein (CRP) levels. Although the coexistence of periodontitis and elevated CRP levels may heighten the risk of mortality, previous studies have not confirmed their synergistic effect. Understanding this interaction is crucial for identifying potential interventions to reduce mortality risk in individuals with periodontitis. This study aimed to assess the synergistic effects of periodontitis and elevated CRP levels on mortality in 7,938 adult individuals who participated in the National Health and Nutrition Examination Study 2001-2004. The association of periodontitis status and CRP levels with mortality was assessed using a survey-weighted Cox model. The interactive effect was estimated; the synergistic effect of CRP levels and periodontitis status on mortality was assessed using the relative excess risk due to interaction (RERI). Periodontitis was diagnosed in 1,065 (13.4%) participants. Compared with the participants without periodontitis and possessing CRP levels of ≤ 0.5 mg/dL, those with periodontitis (hazard ratio [HR], 1.38) or CRP levels of > 0.5 mg/dL (HR 1.23) had higher HRs. The participants with both periodontitis and CRP levels of > 0.5 mg/dL had the highest HR of 2.01. The additive scale interactive effect of the periodontal status and CRP levels, measured using RERI 0.41 (-0.07, 0.95), was positive and nearly significant in the total population. The synergy between the periodontal status and CRP levels was more prominent in the participants aged ≥60 years than that in younger individuals. Periodontitis with high CRP levels may indicate a high mortality rate, indicating the importance of active monitoring and intensive management of periodontitis and inflammatory markers., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Han et al.

Background: Lateral pelvic lymph node dissection is performed for selected patients with rectal cancer with persistent lateral nodal disease after neoadjuvant therapy. This technique has been slow to be adopted in the West because of concerns regarding technical difficulty. This is the first report on the learning curve for lateral pelvic lymph node dissection in the United States or Europe., Objective: This study aimed to analyze the learning curve associated with robotic lateral pelvic lymph node dissection., Design: Retrospective observational cohort., Setting: Tertiary academic cancer center., Patients: Consecutive patients from 2012 to 2021., Intervention: All patients underwent robotic lateral pelvic lymph node dissection., Main Outcome Measures: The primary end points were the learning curves for the maximum number of nodes retrieved and urinary retention, which was evaluated with simple cumulative sum and 2-sided Bernoulli cumulative sum charts., Results: Fifty-four procedures were included. A single-surgeon learning curve (n = 35) and an institutional learning curve are presented in the analysis. In the single-surgeon learning curve, a turning point marking the end of a learning phase was detected at the 12th procedure for the number of retrieved nodes and at the 20th procedure for urinary retention. In the institutional learning curve analysis, 2 turning points were identified at the 13th procedure, indicating progressive improvements for the number of retrieved nodes, and at the 27th procedure for urinary retention. No sustained alarm signals were detected at any time point., Limitations: The retrospective nature, small sample size, and the referral center nature of the reporting institution may limit generalizability., Conclusions: In a setting of institutional experience with robotic colorectal surgery, including beyond total mesorectal excision resections, the learning curve for robotic lateral pelvic lymph node dissection is acceptably short. Our results demonstrate the feasibility of the acquisition of this technique in a controlled setting, with sufficient case volume and proctoring to optimize the learning curve.

La adopción de esta técnica en Occidente ha sido lenta debido a la preocupación por su dificultad técnica. Éste es el primer informe sobre la curva de aprendizaje de la disección de los ganglios linfáticos pélvicos laterales en EE.UU. o Europa.OBJETIVO:El objetivo de este estudio fue analizar la curva de aprendizaje asociada a la disección robótica de los ganglios linfáticos pélvicos laterales.DISEÑO:Cohorte observacional retrospectiva.LUGAR:Centro oncológico académico terciario.PACIENTES:Pacientes consecutivos desde 2012 al 2021.INTERVENCIÓN:Todos los pacientes fueron sometieron a disección robótica de ganglios linfáticos pélvicos laterales.PRINCIPALES MEDIDAS DE RESULTADO:Los criterios de valoración primarios fueron las curvas de aprendizaje tomando en cuenta el mayor número de ganglios recuperados y la retención urinaria que fueron evaluados con gráficos de suma acumulativa simple y de suma acumulativa de Bernoulli de dos caras.RESULTADOS:Fueron incluidos 54 procedimientos. En el análisis se presentan una curva de aprendizaje de un solo cirujano (n = 35) y una curva de aprendizaje institucional. En la curva de aprendizaje de un solo cirujano, se detectó un punto de inflexión que marcaba el final de una fase de aprendizaje en el duodécimo procedimiento para el número de ganglios extraídos y en el vigésimo para la retención urinaria. En el análisis de la curva de aprendizaje institucional, se identificaron dos puntos de inflexión en las intervenciones 13.ª y 26.ª, que indicaron mejoras progresivas en el número de ganglios extraídos, y en la 27.ª en la retención urinaria. No se detectaron señales de alarma sostenidas en ningún momento.LIMITACIONES:La naturaleza retrospectiva, el pequeño tamaño de la muestra y la naturaleza de centro de referencia de la institución informante que pueden limitar la capacidad de generalizarse.CONCLUSIONES:En un entorno de experiencia institucional con cirugía robótica colorrectal incluyendo más allá de las resecciones TME, la curva de aprendizaje para la disección robótica de ganglios linfáticos pélvicos laterales es aceptablemente corta. Nuestros resultados demuestran la viabilidad de la adquisición de esta técnica en un entorno controlado, con un volumen de casos suficiente y una supervisión que puede optimizar la curva de aprendizaje.

Purpose: The purpose of this article is to raise awareness about the importance of diverting from English-centric approaches in the management of dysarthria associated with Parkinson's disease (PD) in the United States, and embracing a language- and culture-specific perspective when working with linguistically and culturally diverse populations within the context of culturally responsive, precision medicine., Method: This tutorial is divided into two primary components: a critical review of language universal and language-specific characteristics of dysarthria associated with PD and their relationship with speech intelligibility, and a practical guide to culturally responsive evidence-based practice for speech-language pathologists., Conclusions: We offer a framework for linguistically and culturally appropriate considerations when working with clients with dysarthria associated with PD. While "universal" representations of dysarthria may be part of the big picture, language-specific contributions to speakers' intelligibility should be carefully examined to maximize treatment outcomes. Additionally, an evidence-based model that fully embraces clients' wishes and values within the context of culturally responsive, precision medicine should be prioritized, a practice that may include the use of interpreters.

Aim: A rigorous examination of the occupational features across cultures helps draw policy recommendations for nurses' quality care practices and good health. This study aimed to explore the differences in work characteristics and health status between Korean and US hospital nurses., Design: For this comparative secondary data analysis study, we constructed a dataset with 304 pairs of nurses from Korea and the United States, matched by age and gender., Methods: We used the data from the 2020 Korean Hospital Nurses Health Behaviors and Health Status study, collected from May to July 2020, and the Nurse Worklife and Wellness Study (NWWS), conducted between November 2020 and February 2021., Results: Compared to nurses in the United States, Korean nurses rated their job-related conditions much lower, had lower intentions to stay in their current workplace and were less satisfied with their jobs. Korean nurses reported that organizational support and employee health resources were less prevalent and their levels of healthy behaviour practice and health status were lower than their US counterparts. Nurses in Korea require better practice environments and employee health support. Adequate workload and staffing levels are needed to improve job conditions for Korean nurses. Organizational support and employee health resources should always be accessible at nurses' workplaces., (© 2024 The Author(s). Nursing Open published by John Wiley & Sons Ltd.)

Chimeric antigen receptor (CAR) T-cell therapy is a human gene therapy product where T cells from a patient are genetically modified to enable them to recognize desired target antigen(s) more effectively. In recent years, promising antitumor activity has been seen with autologous CAR T cells. Since 2017, six CAR T-cell therapies for the treatment of hematological malignancies have been approved by the Food and Drug Administration (FDA). Despite the rapid progress of CAR T-cell therapies, considerable statistical challenges still exist for this category of products across all phases of clinical development that need to be addressed. These include (but not limited to) dose finding strategy, implementation of the estimand framework, use of real-world data in contextualizing single-arm CAR T trials, analysis of safety data and long-term follow-up studies. This paper is the first step in summarizing and addressing these statistical hurdles based on the development of the six approved CAR T-cell products., (© 2024.

Background: Metabolic dysfunction-associated steatohepatitis (MASH), formerly nonalcoholic steatohepatitis, is characterized by fat accumulation and inflammation of the liver and may result in progression to cirrhosis and liver-related events., Objective: To characterize the impact of cirrhosis and progression to liver-related events on costs and health care resource use (HCRU) among MASH patients in the United States., Methods: The study cohort included patients with diagnosed nonalcoholic steatohepatitis ( International Classification of Diseases, Tenth Revision, Clinical Modification code K75.81) in Optum's deidentified Clinformatics Data Mart Database (October 2015 to December 2022) and were stratified by baseline cirrhosis status. Among those without cirrhosis at baseline, patients were further stratified by status of progression to cirrhosis during follow-up. Total HCRU and costs per-person per-year (PPPY) were estimated and compared descriptively between the cohorts. In addition, gamma generalized linear models were used to compare costs PPPY between those with vs without cirrhosis at baseline, as well as with vs without progression during follow-up, while adjusting for baseline patient and disease characteristics. Annual costs per person were also longitudinally modeled using gamma generalized linear mixed models to understand longitudinal changes in costs PPPY while accounting for time correlations within individual patients. Lastly, a series of sensitivity analyses were conducted to assess the impact of study design features and clinical variations of total costs PPPY., Results: A total of 28,576 adults were included, and 9,157 (32.0%) had baseline cirrhosis; of the 19,419 without baseline cirrhosis, a total of 4,235 (21.8%) progressed over follow-up. Mean (SD) HCRU and costs PPPY were higher among patients with cirrhosis ($110,403 [$226,037]) than without ($28,340 [$61,472]; P < 0.01) and among those with progression ($58,128 [$102,626]) than without ($20,031 [$39,740]; P < 0.01). Costs remained significantly greater when adjusted for covariates, with a risk ratio (95% CI) of 1.99 (1.89-2.09) when comparing with vs without baseline cirrhosis and 2.28 (2.15-2.42) when comparing with vs without progression over follow-up. Costs increased with each subsequent year, to 21% by year 6 among those with cirrhosis at baseline and 49% among those without baseline cirrhosis who progressed., Conclusions: The financial burden of MASH is substantial and significantly greater among those with cirrhosis or disease progression. Although patients without cirrhosis incur lower burden, the increase over time is greater and associated with progression. Therapies that slow progression may help alleviate the financial burden, and strategies are needed to identify patients with MASH at risk of progressing to cirrhosis.

Objective: The COVID-19 pandemic exacerbated experiences of loss and grief for many individuals and posed a challenging mental health crisis. Compared to studies examining a singular type of loss, the present study investigated the cumulative impacts of COVID-related losses on anxiety and depressive symptoms and examined whether meaning in life, marital status, or relationship quality offered a protective moderating role., Method: A cross-sectional online survey was conducted approximately 1 year into the pandemic among 434 diverse individuals (32.0% White; 52.1% women; M = 34.7) in the United States. Measures included: General Anxiety Disorder-7, Patient Health Questionnaire-9, Quality of Marriage Index, and 26 loss items with corresponding grief ratings.age = 34.7) in the United States. Measures included: General Anxiety Disorder-7, Patient Health Questionnaire-9, Quality of Marriage Index, and 26 loss items with corresponding grief ratings., Results: Results using linear mixed models demonstrated strong positive links between loss and both anxiety and depressive symptoms, although the association between loss and anxiety was stronger for women. The association between loss and anxiety was attenuated at high levels of meaning in life compared to average and low levels of meaning and for married individuals compared to unmarried participants. Being married also buffered the impact of loss on depressive symptoms., Conclusions: Findings indicate that cumulative pandemic-related loss is associated with anxiety and depressive symptoms, and that meaning in life and romantic relationships may be promising interventional targets; though, these findings may change over the course of the pandemic.

Objective: Racial and ethnic disparities have been well-described among surgical specialties; however, variations in underrepresented in medicine (URiM) representation between these specialties have not previously been quantified., Methods: Data collected from Accreditation Council for Graduate Medical Education (ACGME) annual reports were used to derive the Diversity of Surgical Trainee Index (DoSTI), which was calculated as the proportion of URiM residents and fellow physicians within a given surgical specialty, relative to the overall proportion of URiM trainees within all surgical and non-surgical ACGME-accredited programs in the same academic year., Results: From 2013 to 2022, a total of 108,193 ACGME-accredited residency programs trained 1,296,204 residents and fellows in the United States. Of these, 14.1% (n = 182,680) of trainees self-identified as URiM over the study period. The mean DoSTI among all surgical specialties was 0.80 (standard error, 0.01) compared with all ACGME-accredited programs. High DoSTI specialties incorporated significantly higher proportions of trainees who identify as Hispanic (8.7% vs 6.3%) and Black or African American (5.2% vs 2.5%) when compared with low DoSTI specialties (P < .0001 each). General surgery (1.06 ± 0.01), plastic surgery (traditional) (1.12 ± 0.06), vascular surgery (integrated) (0.96 ± 0.03), and vascular surgery (traditional) (0.94 ± 0.06) had the highest DoSTI (P < .05 each vs composite). On linear regression analysis, only ophthalmology (+0.01/year; R 2  = 0.41; P = .019), orthopedic surgery (+0.01/year; R 2  = 0.33; P = .047), otolaryngology (+0.02/year; R 2  = 0.86; P < .001), and pediatric surgery (+0.06/year; R 2  = 0.33; P = .048) demonstrated an annual increase in DoSTI., Conclusions: The DoSTI is a novel metric used to quantify the degree of URiM representation among surgical specialties. DoSTI has revealed specialty-specific variations in racial/ethnic minority representation among surgical training programs. This metric may be used to improve provider awareness and identify high performing DoSTI specialties to highlight best practices to ultimately recruit a more diverse surgical workforce., Competing Interests: Disclosures None., (Published by Elsevier Inc.)

Background: The legal climate for cannabis use has dramatically changed with an increasing number of states passing legislation legalizing access for medical and recreational use. Among cancer patients, cannabis is often used to ameliorate adverse effects of cancer treatment. Data are limited on the extent and type of use among cancer patients during treatment and the perceived benefits and harms. This multicenter survey was conducted to assess the use of cannabis among cancer patients residing in states with varied legal access to cannabis., Methods: A total of 12 NCI-Designated Cancer Centers, across states with varied cannabis-access legal status, conducted surveys with a core questionnaire to assess cannabis use among recently diagnosed cancer patients. Data were collected between September 2021 and August 2023 and pooled across 12 cancer centers. Frequencies and 95% confidence intervals for core survey measures were calculated, and weighted estimates are presented for the 10 sites that drew probability samples., Results: Overall reported cannabis use since cancer diagnosis among survey respondents was 32.9% (weighted), which varied slightly by state legalization status. The most common perceived benefits of use were for pain, sleep, stress and anxiety, and treatment side effects. Reported perceived risks were less common and included inability to drive, difficulty concentrating, lung damage, addiction, and impact on employment. A majority reported feeling comfortable speaking to health-care providers though, overall, only 21.5% reported having done so. Among those who used cannabis since diagnosis, the most common modes were eating in food, smoking, and pills or tinctures, and the most common reasons were for sleep disturbance, followed by pain and stress and anxiety with 60%-68% reporting improved symptoms with use., Conclusion: This geographically diverse survey demonstrates that patients use cannabis regardless of its legal status. Addressing knowledge gaps concerning benefits and harms of cannabis use during cancer treatment is critical to enhance patient-provider communication., (Published by Oxford University Press 2024.)

Background: The Elixhauser Comorbidity Index (ECI) is widely used, but its performance in homeless populations has not been evaluated., Objectives: Using a national sample of inpatients, this study compared homeless and nonhomeless inpatients on common clinical diagnoses and evaluated ECI performance in predicting mortality among homeless inpatients., Research Design: A retrospective study was conducted using 2019 National Inpatient Sample (NIS) data, the largest publicly available all-payer inpatient health care database in the United States., Subjects: Among 4,347,959 hospitalizations, 78,819 (weighted 1.8%) were identified as homeless., Measures: The ECI consists of 38 medical conditions; homelessness was defined using the International Classification of Diseases Tenth Revision Clinical Modification (ICD-10-CM) diagnostic code, and clinical conditions were based on the Clinical Classifications Software Refined (CCSR) for ICD-10-CM., Results: Leading clinical diagnoses for homeless inpatients included schizophrenia and other psychotic disorders (13.3%), depressive disorders (9.4%), and alcohol-related disorders (7.2%); leading diagnoses for nonhomeless inpatients were septicemia (10.2%), heart failure (5.2%), and acute myocardial infarction (3.0%). Metastatic cancer and liver disease were the most common ECI diagnoses for both homeless and nonhomeless inpatients. ECI indicators and summary scores were predictive of in-hospital mortality for homeless and nonhomeless inpatients, with all models yielding concordance statistics above 0.80, with better performance found among homeless inpatients., Conclusions: These findings underlie the high rates of behavioral health conditions among homeless inpatients and the strong performance of the ECI in predicting in-hospital mortality among homeless inpatients, supporting its continued use as a case-mix control method and predictor of hospital readmissions., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Introduction: Residential food environments are one of the important determinants of cardiovascular health. However, past literature has been limited by short-term follow-ups, time-invariant environmental measurements at baseline, and/or not investigating both healthy and unhealthy aspects of the food environment. This study examines the effects of time-varying healthy and unhealthy food environments on incident cardiovascular disease (CVD) over 10 years, extracting data from the Health and Retirement Study (2006-2016; N=10,413)., Methods: Cox proportional hazards modeling was performed with inverse probability weighting to assess the association between time-varying food environmental measures (i.e., densities of grocery stores, supercenters/club stores, full-service restaurants, and fast-food restaurants) and incident CVD over 10 years. Education level and race/ethnicity were tested as potential moderators. Analyses were conducted in 2022-2023., Results: Race/ethnicity had a significant interaction effect with supercenters/club stores and indicated that a 1-standard-deviation increase in the density of supercenters/club stores was associated with a 6%-8% lower risk of incident CVD in non-Hispanic Black (HR=0.78, 95% CI=0.70-0.87) and Hispanic older adults (HR=0.69, 95% CI=0.50-0.96), but not non-Hispanic White older adults. Additionally, education had a significant interaction effect with full-service restaurants, indicating that a 1-standard-deviation increase in the density of full-service restaurants was associated with a 10% lower risk of incident CVD in individuals with 13+ years of schooling, but not those with 0-12 years of schooling., Conclusions: Findings suggest that public policymakers should be aware of the benefits and nuances of varying food environment components as they can contribute to positive or negative cardiovascular health., (Copyright © 2024.

One of the justifiable criticisms of human genetic studies is the underrepresentation of participants from diverse populations. Lack of inclusion must be addressed at-scale to identify causal disease factors and understand the genetic causes of health disparities. We present genome-wide associations for 2068 traits from 635,969 participants in the Department of Veterans Affairs Million Veteran Program, a longitudinal study of diverse United States Veterans. Systematic analysis revealed 13,672 genomic risk loci; 1608 were only significant after including non-European populations. Fine-mapping identified causal variants at 6318 signals across 613 traits. One-third ( n = 2069) were identified in participants from non-European populations. This reveals a broadly similar genetic architecture across populations, highlights genetic insights gained from underrepresented groups, and presents an extensive atlas of genetic associations.

Background: Lower income is associated with high incident cardiovascular disease (CVD) and mortality. CVD is an important cause of morbidity and mortality in cancer survivors. However, there is limited research on the association between income, CVD, and mortality in this population., Methods: This study utilized nationally representative data from the National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey evaluating the health and nutritional status of the US population. Our study included NHANES participants aged ≥20 years from 2003-2014, who self-reported a history of cancer. We evaluated the association between income level, prevalence of CVD, and all-cause mortality. All-cause mortality data was obtained through public use mortality files. Income level was assessed by poverty-income ratio (PIR) that was calculated by dividing family (or individual) income by poverty guideline. We used multivariable-adjusted Cox proportional hazard models through a backward elimination method to evaluate associations between PIR, CVD, and all-cause mortality in cancer survivors., Results: This cohort included 2,464 cancer survivors with a mean age of 62 (42% male) years. Compared with individuals with a higher PIR tertiles, those in the lowest PIR tertile had a higher rate of pre-existing CVD and post-acquired CVD. In participants with post-acquired CVD, the lowest PIR tertile had over two-fold increased risk mortality (Hazard Ratio (HR) = 2.17; 95% CI: 1.27-3.71) when compared to the highest PIR tertile. Additionally, we found that PIR was as strong a predictor of mortality in cancer survivors as CVD. In patients with no CVD, the lowest PIR tertile continued to have almost a two-fold increased risk of mortality (HR = 1.72; 95% CI: 1.69-4.35) when compared to a reference of the highest PIR tertile., Conclusions: In this large national study of cancer survivors, low PIR is associated with a higher prevalence of CVD. Low PIR is also associated with an increased risk of mortality in cancer survivors, showing a comparable impact to that of pre-existing and post-acquired CVD. Urgent public health resources are needed to further study and improve screening and access to care in this high-risk population., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Yogeswaran et al.

Background: Drug mortality risks vary among industries, creating distinctive geographic patterns across US counties. However, less is known about how local labor market structure relates to drug overdose mortality amid the synthetic opioid era in the United States. This study investigates the relationship between industry-specific job composition and drug overdose mortality at the county level while exploring how fentanyl's presence in illicit drug supplies may moderate the relationship., Methods: Data were derived from the National Center for Health Statistics' Multiple Cause of Death files for the rates of drug overdose mortality of any intent, linked with four other sources on industry-specific job shares, drug supply, and county-level sociodemographic characteristics and opioid prescribing rates from the US Census Bureau, the CDC, and the Drug Enforcement Administration. Negative binomial regression models were employed to examine associations between county industry-specific job composition and drug overdose mortality, with tests for moderating effects of state-level fentanyl seizure rates., Results: Our models indicate negative associations between job shares of manufacturing, retail trade, and educational services industries and drug overdose mortality. Positive associations were found for arts/entertainment/recreation and public administration. State-level fentanyl seizure rates had moderating effects on administrative/support/waste management/remediation (A/S/WM/R) and educational services., Conclusion: Counties with a higher concentration of arts/entertainment/recreation and public administration jobs need targeted efforts to mitigate drug-related overdose risks. Additionally, areas with higher concentrations of A/S/WM/R service jobs, particularly where fentanyl seizure rates are higher, may require proactive harm reduction strategies for reducing overdose risks., (© 2024 The Authors.

Objective: We conducted a national US study of SARS-CoV-2 seroprevalence by Social Vulnerability Index (SVI) that included pediatric data and compared the Delta and Omicron periods during the COVID-19 pandemic. The objective of the current study was to assess the association between SVI and seroprevalence of infection-induced SARS-CoV-2 antibodies by period (Delta vs Omicron) and age group., Methods: We used results of infection-induced SARS-CoV-2 antibody assays of clinical sera specimens (N = 406 469) from 50 US states from September 2021 through February 2022 to estimate seroprevalence overall and by county SVI tercile. Bivariate analyses and multilevel logistic regression models assessed the association of seropositivity with SVI and its themes by age group (0-17, ≥18 y) and period (Delta: September-November 2021; Omicron: December 2021-February 2022)., Results: Aggregate infection-induced SARS-CoV-2 antibody seroprevalence increased at all 3 SVI levels; it ranged from 25.8% to 33.5% in September 2021 and from 53.1% to 63.5% in February 2022. Of the 4 SVI themes, socioeconomic status had the strongest association with seroprevalence. During the Delta period, we found significantly more infections per reported case among people living in a county with high SVI (odds ratio [OR] = 2.76; 95% CI, 2.31-3.21) than in a county with low SVI (OR = 1.65; 95% CI, 1.33-1.97); we found no significant difference during the Omicron period. Otherwise, findings were consistent across subanalyses by age group and period., Conclusions: Among both children and adults, and during both the Delta and Omicron periods, counties with high SVI had significantly higher SARS-CoV-2 antibody seroprevalence than counties with low SVI did. These disparities reinforce SVI's value in identifying communities that need tailored prevention efforts during public health emergencies and resources to recover from their effects., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Allergic bronchopulmonary aspergillosis and invasive fungal diseases represent distinct infectious entities that cause significant morbidity and mortality. Currently, administered inhaled antifungal therapies are unapproved, have suboptimal efficacy, and are associated with considerable adverse reactions. The emergence of resistant pathogens is also a growing concern. Inhaled antifungal development programs are challenged by inadequate nonclinical infection models, highly heterogenous patient populations, low prevalence rates of fungal diseases, difficulties defining clinical trial enrollment criteria, and lack of robust clinical trial endpoints. On 25 September 2020, the US Food and Drug Administration (FDA) convened a workshop with experts in pulmonary medicine and infectious diseases from academia, industry, and other governmental agencies. Key discussion topics included regulatory incentives to facilitate development of inhaled antifungal drugs and combination inhalational devices, limitations of existing nonclinical models and clinical trial designs, patient perspectives, and industry insights., Competing Interests: Potential conflicts of interest.

Purpose: This study was designed to provide a comprehensive and up-to-date understanding of population-level reoperation rates and incremental healthcare costs associated with reoperation for patients who underwent breast-conserving surgery (BCS)., Methods: This is a retrospective cohort study using Merative™ MarketScan ® commercial insurance data and Medicare 5% fee-for-service claims data. The study included females aged 18-64 years in the commercial cohort and females aged 18 years and older in the Medicare cohort, who underwent initial BCS for breast cancer in 2017-2019. Reoperation rates within a year of the initial BCS and overall 1-year healthcare costs stratified by reoperation status were measured., Results: The commercial cohort included 17,129 women with a median age of 55 (interquartile range [IQR] 49-59) years, and the Medicare cohort included 6977 women with a median age of 73 (IQR 69-78) years. Overall reoperation rates were 21.1% (95% confidence interval [CI] 20.5-21.8%) for the commercial cohort and 14.9% (95% CI 14.1-15.7%) for the Medicare cohort. In both cohorts, reoperation rates decreased as age increased, and conversion to mastectomy was more prevalent among younger women in the commercial cohort. The mean healthcare costs during 1 year of follow-up from the initial BCS were $95,165 for the commercial cohort and $36,313 for the Medicare cohort. Reoperations were associated with 24% higher costs in both the commercial and Medicare cohorts, which translated into $21,607 and $8559 incremental costs, respectively., Conclusions: The rates of reoperation after BCS have remained high and have contributed to increased healthcare costs. Continuing efforts to reduce reoperation need more attention., (© 2024. The Author(s).)

Objective: To compare the cost-utility of initial management of high-grade T1 non-muscle invasive bladder cancer (HGT1 NMIBC) with intravesical BCG vs immediate radical cystectomy. High-risk NMIBC patients may climb a costly ladder of treatments, culminating in radical cystectomy for oncologic or symptomatic benefit in up to one-third. This high healthcare resource utilization presents a challenging dilemma in balancing sufficiently aggressive management with cost, toxicity, and quality-of-life., Methods: Cost-utility of initially managing HGT1 with intravesical BCG and early radical cystectomy with ileal conduit urinary diversion was compared using decision-analytic Markov models. Five-year oncologic outcomes, adverse event rates, and published utility values were extracted from literature. Costs were calculated from a US Medicare perspective in 2021 US dollars. Sensitivity analysis identified drivers of cost and break-even points for recurrence and progression., Results: Mean costs were $26,093 for intravesical BCG and $39,720 for immediate radical cystectomy, though cystectomy generated a gain of 2.2 quality-adjusted life years (QALYs) compared to intravesical BCG. Immediate cystectomy was a more cost-effective management strategy for HGT1 NMIBC with an incremental CE ratios (ICER) of $7120/QALY. The costs associated with cystectomy, TURBT, and BCG toxicity had the greatest impact on ICER. One-way sensitivity analysis demonstrated that intravesical BCG became a cost-effective management strategy if the 5-year recurrence rate of HG T1 was less than 56% or the 5-year progression rate to MIBC was less than 4%., Conclusion: At current prices, treatment of high-grade T1 NMIBC with early radical cystectomy is more cost-effective management strategy than initial treatment with intravesical BCG., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Introduction: E-cigarettes have rapidly grown in use among U.S. adolescents; in response, the Food and Drug Administration (FDA) engaged in an "enforcement policy on banned e-cigarette flavors" ("enforcement action") for pod-based e-cigarettes in January 2020, which accounted for most U.S. e-cigarette sales. No literature has yet examined long-term changes in e-cigarette sales patterns changed in relation to the FDA enforcement action., Aims and Methods: We analyzed U.S. e-cigarette sales using Nielsen retail scanner data between March 2017 and December 2021, describing e-cigarette sales trends overall, by device type, and by flavor category. We also performed joinpoint regression analysis on the sales trends to detect significant changes in the rate of change of sales over time., Results: The FDA enforcement action was associated with a sharp initial decrease in prefilled pod dollar sales, followed by a steady increase from April 2020 through the end of 2021, growing beyond the previous maximum in August 2019. We also observed a dramatic change in the composition of flavors sold: A large decline in mint-flavored pod sales was offset by a similar increase in menthol-flavored sales. Simultaneously, disposable product sales increased nearly ten-fold from July 2019 to July 2020 before stabilizing, dominated by fruit-flavored products., Conclusions: Our findings suggest rapid product substitution without a long-term decline in e-cigarette sales in association with the enforcement action, along with a growing dominance of youth-friendly flavors, contrasting against FDA policy goals. Our study revealed the weakness of the "patchy" enforcement action, raising concern about its unintended consequences as consumption simply shifted to other e-cigarette products., Implications: This is the first detailed longitudinal study on e-cigarette sales trends in the United States following the FDA flavor enforcement action, with novel findings on flavor trends and their relation to policy events. We report sales overall, by product type, and by flavor category, and highlight several important trends following the action, such as the rise and persistence of disposable e-cigarettes increasingly and overwhelmingly dominated by youth-friendly flavors, and likely substitution of prefilled e-cigarette flavors without any long-term decline in sales. Our results highlight the weaknesses of "patchy" regulation and suggest the need for a more comprehensive approach to flavor regulation., (© The Author(s) 2023.

Background: Comprehensive vascular care includes both arterial and venous disease management. However, operative training in venous disease is often significantly overshadowed by arterial procedures, despite the public health burden of acute and chronic venous disease. The purpose of this study is to evaluate the case-mix and volume of venous procedures performed by graduating integrated vascular surgery residents and fellows in the United States., Methods: Accreditation Council for Graduate Medical Education national operative log reports were compiled for graduating integrated VSR (vascular surgery residency) and traditional vascular surgery fellowship (VSF) trainees from academic years 2013 to 2022. Only cases categorized as "surgeon fellow", "surgeon chief", or "surgeon junior" were included. Linear regression analysis was utilized to evaluate trends in case-mix and volume., Results: Over the 10-year study period, total vascular cases increased for both VSR (mean 870.5 ± 9.3 cases, annual change +9.5 cases/year, R 2  = 0.77, P < 0.001) and VSF (mean 682.1 ± 6.9 cases, annual change +6.7 cases/year, R 2  = 0.85, P < 0.001) trainees. Concurrently, the proportion of venous cases in the VSR group decreased from 12.5% to 7.3% (annual change -3.7 cases/year, R 2  = 0.72, P < 0.001). VSR trainees experienced an annual decrease in 4 of the top 5 venous case types performed, including venous angioplasty/stenting (-1.6 cases/year, P = 0.002), vena cava filter placement (-0.9 cases/year, P = 0.002), endoluminal ablation (-0.2 cases/year, P = 0.47), diagnostic venography (-1.7 cases/year, P < 0.001), and varicose vein treatment (-1.0 cases/year, P < 0.001). Venous cases proportions also decreased in the VSF group from 8.4% to 6.2% (annual change -2.2 cases/year, R 2  = 0.54, P = 0.002). VSF trainees experienced an annual decrease in 4 of the top 5 venous case types, including venous angioplasty/stenting (-1.5 cases/year, P = 0.003), diagnostic venography (-1.2 cases/year, P < 0.001), vena cava filter placement (-0.2 cases/year, P = 0.44), endoluminal ablation (-0.6 cases/year, P < 0.001), and varicose vein treatment (-0.1 cases/year, P = 0.04). Both VSR and VSF trainee groups graduated with fewer than 5 cases for each of the following venous procedures-percutaneous mechanical thrombectomy, venous thrombolysis, open venous reconstruction, sclerotherapy, venous embolectomy, portal-systemic shunting, venous ulceration treatment, and arteriovenous malformation treatment., Conclusions: Current vascular residents and fellows have limited exposure to venous procedures, in part due to a proportional decline in venous cases. More robust venous operative experience is needed during surgical training. Further studies are needed to understand whether this discrepancy in venous and arterial training impacts career progression and patient outcomes., (Copyright © 2023 Elsevier Inc.

Introduction: Prior research on the effects of social media promotion of tobacco products has predominantly relied on survey-based self-report measures of marketing exposure, which potentially introduce endogeneity, recall, and selection biases. New approaches can enhance measurement and help better understand the effects of exposure to tobacco-related messages in a dynamic social media marketing environment. We used geolocation-specific tweet rate as an exogenous indicator of exposure to smokeless tobacco (ST)-related content and employed this measure to examine the influence of social media marketing on ST sales., Aims and Methods: Autoregressive error models were used to analyze the association between the ST-relevant tweet rate (aggregated by 4-week period from February 12, 2017 to June 26, 2021 and scaled by population density) and logarithmic ST unit sales across time by product type (newer, snus, conventional) in the United States, accounting for autocorrelated errors. Interrupted time series approach was used to control for policy change effects., Results: ST product category-related tweet rates were associated with ST unit sales of newer and conventional products, controlling for price, relevant policy events, and the coronavirus disease 2019 (COVID-19) pandemic. On average, 100-unit increase in the number of newer ST-related tweets was associated with 14% increase in unit sales (RR = 1.14; p = .01); 100-unit increase in conventional ST tweets was associated with ~1% increase in unit sales (p = .04). Average price was negatively associated with the unit sales., Conclusions: Study findings reveal that ST social media tweet rate was related to increased ST consumption and illustrate the utility of exogenous measures in conceptualizing and assessing effects in the complex media environment., Implications: Tobacco control initiatives should include efforts to monitor the role of social media in promoting tobacco use. Surveillance of social media platforms is critical to monitor emerging tobacco product-related marketing strategies and promotional content reach. Exogenous measures of potential exposure to social media messages can supplement survey data to study media effects on tobacco consumption., (© The Author(s) 2024.

Objectives: To investigate trends in forgone medical care, basic needs disruption, financial and mental health disruption, engagement of preventive behaviours guidelines, and perceived severity of COVID-19 among community-living Medicare beneficiaries in the USA with and without a self-reported history of depression from Summer 2020 to Winter 2021., Design/setting: A repeated cross-sectional study using a nationally representative sample of Medicare beneficiaries of three rounds of survey data from the Medicare Current Beneficiary Survey COVID-19 Supplement Public Use Files: Summer 2020, Fall 2020 and Winter 2021., Participants: A total of 28 480 community-dwelling Medicare beneficiaries., Main Outcome Measures: Forgone medical care, basic needs disruption, financial and mental health disruption, engagement of preventive behaviours guidelines, and perceived severity of COVID-19., Results: In the study sample, 7629 (27%) had a history of depression. After adjusting for potential confounders, weighted multivariable logistic regression models showed that Medicare beneficiaries with a history of depression had higher odds of foregone medical care (OR: 1.29, 95% CI 1.16 to 1.42, p<0.001), of basic need disruption (OR: 1.49, 95% CI 1.33 to 1.67, p<0.001), and of financial and mental health disruption (OR: 1.75, 95% CI 1.60 to 1.91, p<0.001) during the COVID-19 pandemic when compared with those without a history of depression. No statistically significant differences were observed in engagement of essential preventive behaviours or perception of COVID-19 severity., Conclusions: COVID-19 pandemic may exacerbate existing barriers to healthcare access and financial and social needs, possibly leading to persistent unmet needs among Medicare beneficiaries with a history of depression beyond the pandemic., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Along with the trend of a steady utilization decline in the U.S. nursing home beds, post-acute care (PAC) utilization at the skilled nursing facilities has declined. This study was a cross-sectional, retrospective review of hospital discharge-based claim data. We evaluate the factors associated with utilizing post-acute care at rehabilitation facilities among those with extremity fractures in the state of Nevada. All Nevada hospital discharges of aged ≥65 years with extremity fractures between 2018 and 2021 were divided to post-acute care locations by (1) rehabilitation facilities (skilled nursing facility and inpatient rehabilitation facility) and (2) homes (with and without services). PAC utilization at facilities declined from 55.1% in 2018 to 49.7% in 2021 ( P  < .001). In response, PAC utilization at homes continuously upwards, particularly, homes with services from 18.8% in 2018 to 24.5% in 2021 ( P  < .001). Older age, female, lower extremity fractures, comorbidities, and Medicare beneficiaries were associated with higher probabilities of utilizing post-acute rehabilitation facilities. Racial minorities, COVID-19 pandemic, upper extremities, Medicaid beneficiaries, rural hospitals, and prolonged hospital length of stay were associated with lower probabilities of PAC utilization at facilities. Caregiver burdens and workforce training is urgently warranted to respond to this utilization shift.

Aims: This study assessed the budget impact of resmetirom as a treatment for adults with non-cirrhotic non-alcoholic steatohepatitis (NASH) with moderate-to-advanced liver fibrosis and estimated total costs for a hypothetical private payer in the United States., Materials and Methods: A three-year budget impact analysis based on an open cohort state transition model was developed for a hypothetical one-million-member private health plan. The comparator was Standard of Care (SOC), defined as routine care for non-cirrhotic NASH patients with moderate-to-advanced liver fibrosis. Each year, the number of resmetirom treatment-eligible patients was estimated through prevalent, incident, and diagnostic rate estimates. Costs included resources incurred by the medical and pharmacy benefits of private payers, including resmetirom drug acquisition costs, diagnosis and monitoring, other medical and other prescription costs stratified by disease progression status (i.e. non-cirrhotic vs. cirrhotic/advanced liver diseases). Resmetirom adverse event management costs were included in sensitivity analysis. Drug costs were estimated based on the average wholesale acquisition cost as of March 2024. Other costs were based on published sources and inflated to 2023 US dollars. Budget impact outcomes were presented in aggregate, net, and on a per-member per-month (PMPM) basis., Results: Compared with a scenario without resmetirom, the introduction of resmetirom yielded results ranging from 50 to 238 treated patients, net budget impact of $2.2 to $9.5 million, and PMPM from $0.19 to $0.80 over years one and three. Net costs excluding resmetirom declined over time. In sensitivity analyses, results were most sensitive to diagnostic and epidemiologic inputs., Limitations: Market shares are based on internal forecasts, a short time horizon, average treatment effects, and other limitations common to BIMs., Conclusion: The adoption of resmetirom on the formulary for the treatment of non-cirrhotic NASH with moderate-to-advanced liver fibrosis resulted in a moderate increase in budget impact with declining costs related to NASH progression.

In the western United States, Culex tarsalis is the most important vector of West Nile virus. Insecticides containing permethrin or other pyrethroid compounds are commonly used to control these mosquitoes. Because of the range of environments where Cx. tarsalis are found, this species is under insecticide pressure from both vector control and agricultural spraying. Mosquito populations may evolve resistance through mechanisms such as target site insensitivity, including the frequently identified knockdown resistance (kdr) mutations. Prevalence of permethrin resistance was determined for Cx. tarsalis from 5 southern California field sites representing 2 distinct valley regions (Coachella Valley and Inland Valley), which are geographically separated by the north-south-running Peninsular Mountain Ranges. These two valley regions are >100 km apart and vary considerably in their environmental and habitat characteristics. Permethrin resistance in mosquito populations was determined by the Centers for Disease Control and Prevention (CDC) bottle bioassay, using glass bottles coated with permethrin at 0.19 μg/cm2 of internal surface. Permethrin resistance was evident in Cx. tarsalis populations from the Coachella Valley field sites with all sites showing similar mortality in the bottle bioassay, while Cx. tarsalis from the Inland Valley field sites were largely susceptible to permethrin, with mortality rates that were similar to a susceptible lab strain of Cx. tarsalis., (Copyright © 2023 by The American Mosquito Control Association, Inc.)
