Purpose: To identify risk factors associated with the development of corneal edema (CE) and the need for corneal transplantation following cataract surgery., Design: Retrospective cohort study., Methods Setting: Nation-wide sample of Medicare beneficiaries from 2011-2015., Study Population: Medicare beneficiaries aged over 65 years who received cataract surgery between 2011-2014 with at least 1 year of continuous follow-up. Data was retrieved from the Denominator and Physician Supplier Part B file from the Center for Medicare and Medicaid Services., Main Outcome(s) and Measure(s): The main outcome was the association between demographic characteristics (e.g., age, sex, race/ethnicity) and systemic factors including diabetes status, hypertension, and tobacco use on the incidence of CE and the subsequent need for corneal transplantation following cataract surgery., Results: Among 187,746 beneficiaries, 67,734 had diabetes and 120,012 did not. Beneficiaries with diabetes were more likely to develop CE compared to those without (Odds ratio [OR] 1.19, 95% Confidence Interval [CI] [1.02-1.40]). Compared to those aged 65-74, beneficiaries aged 75-84 and over 85 were more likely to develop CE (OR 1.29 [1.09-1.52]) and OR 1.96 [1.55-2.46], respectively). Asian (OR 2.42 [1.66-3.40]), Hispanic (OR 2.60 [1.73-3.74]), and North American Native (OR 3.59 [1.78-6.39]) race was associated with increased likelihood of developing CE. North American Native beneficiaries had higher risk of requiring corneal transplantation compared to White beneficiaries (OR 9.30 [2.26-25.31]). Female sex decreased likelihood of requiring corneal transplantation post-operatively (OR 0.56 [0.36-0.87]). Amongst those with diabetes, the presence of proliferative diabetic retinopathy increased the likelihood of developing CE (OR 1.94 [1.05-3.39])., Conclusion: Older age, diabetes, and non-White race elevate the risk of CE following cataract surgery, with race incurring the highest risk. Further research is needed to understand the factors underlying the significantly increased risk of CE in racial and ethnic minorities within the United States., (Copyright © 2024 Elsevier Inc.

The reported prevalence of autism spectrum disorder (ASD) has more than tripled in the past two decades in the United States, due in part to improved screening and diagnostic techniques. Epidemiologic data on ASD, however, are largely limited to population-based surveillance systems. We examined epidemiologic patterns in ASD diagnoses among inpatients aged 1-20 years, using data from the Kids' Inpatient Database (KID) from 1997 to 2019. ASD cases were identified using ICD-9-CM and ICD-10-CM codes. Of 9,267,881 hospital discharges studied, 110,090 (1.19%) had a diagnosis of ASD. The prevalence of ASD was higher among males compared to females (1.53% vs. 0.54%) and was highest among non-Hispanic Whites (1.28% vs. 0.95% in non-Hispanic Blacks, 0.94% in Hispanics, and 1.18% in Other races). ASD prevalence increased from 0.18% to 1997 to 3.36% in 2019 (Z= -273.40, p < 0.001). The absolute increase was higher among males compared to females (0.26-4.90% vs. 0.08-1.77%) and among non-Hispanic Whites (0.18-2.88%) compared to non-Hispanic Blacks (0.23-2.72%), Hispanics (0.14-2.60%), and Other races (0.19-2.97%). The epidemiologic patterns of ASD based on inpatient data are generally consistent with reports from the community-based autism surveillance system. Our findings indicate that KID and other health services data might play a complementary role in ASD surveillance., (© 2023.

Older adults aged 70 and older who drive have higher crash death rates per mile driven compared to middle aged (35-54 years) adults who drive in the US. Prior studies have found that depression and or antidepressant medication use in older adults are associated with an increase in the vehicular crash rate. Using data from the prospective multi-site AAA Longitudinal Research on Aging Drivers Study, this analysis examined the independent and interdependent associations of self-reported depression and antidepressant use with driving behaviors that can increase motor vehicle crash risk such as hard braking, speeding, and night-time driving in adults over age 65. Of the 2951 participants, 6.4% reported having depression and 21.9% were on an antidepressant medication. Correcting for age, race, gender, and education level, participants on an antidepressant had increased hard braking events (1.22 [1.10-1.34]) but self-reported depression alone was not associated with changes in driving behaviors., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: To compare thyroid cancer incidence rates and trends between Korean, non-Korean Asian, and non-Hispanic White populations in the United States, and between the US Korean population and the South Korean population., Method: Population-based analysis of cancer incidence data. Cases of thyroid cancer diagnosed during 1999-2014 from the Korean Central Cancer Registry (KCCR) and the Surveillance, Epidemiology, and End Results (SEER) 9 detailed Asian/Pacific Islander subgroup incidence and population dataset were included. Incidence rates were obtained from the datasets, and annual percent change (APC) of the incidence rates was calculated using Joinpoint regression analysis., Results: Thyroid cancer incidence rate for 1999-2014 was significantly higher for South Korea (48.05 [95% CI 47.89-48.22] per 100,000 person-years) than for the US Korean population (11.12 [95% CI 10.49-11.78] per 100,000 person-years), which was slightly higher than the Non-Korean Asian population (10.23 [95% CI 10.02-10.43] per 100,000 person-years), and slightly lower than the Non-Hispanic White population (12.78 [95% CI 12.69-12.87] per 100,000 person-years). Incidence rates in South Korea increased dramatically (average APC 17.9, 95% CI 16.0-19.9), significantly higher than the US Korean population (average APC 5.0, 95% CI 3.1-6.8), which was similar to the non-Korean Asian (average APC 2.5, 95% CI 0.9-4.2) and the non-Hispanic White (average APC 5.1, 95% CI 4.7-5.6) populations., Conclusions: South Korea's high thyroid cancer incidence rates cannot be attributed to genetic factors, but are likely due to health care system factors., Level of Evidence: 3 Laryngoscope, 134:4156-4160, 2024., (© 2024 The American Laryngological, Rhinological and Otological Society, Inc.)

Purpose: The purpose of this study was to investigate the impact of demographic characteristics and psychiatric comorbidity on the prevalence of dry eye disease in the American geriatric population., Methods: Data were collected from a 2011 nationwide sample of Medicare beneficiaries aged 65 years and older (N = 1,321,000). Age, sex, race/ethnicity, residential area, climate region, and income, along with psychiatric comorbidities including depression and anxiety, were collected. Multivariable logistic regression models were used to assess the relationship between demographic and psychiatric factors and the prevalence of dry eye disease., Results: Among 21,059 patients with clinically significant dry eye, women had higher odds of having dry eye compared with men [odds ratio (OR) 2.03, 95% confidence interval (1.97-2.10)]. Asian and Native American patients had increased odds of having dry eye compared with White patients [OR 1.85 (1.69-2.02) and OR 1.51 (1.19-1.93)], while Black patients were less likely to have dry eye [OR 0.83 (0.79-0.87)]. Patients aged 75 to 84 years and 85+ were more likely to have dry eye compared with those aged 65 to 74 years [OR 1.49 (0.45-1.53) and OR 1.54 (1.48-1.60)]. Having both depression and anxiety were associated with higher odds of having dry eye [OR 2.38 (2.22-2.55)] compared with having depression alone [OR 1.95 (1.86-2.04)] or anxiety alone [OR 2.22 (2.10-2.35)]., Conclusions: Significant racial and regional disparities in dry eye prevalence were found. Psychiatric association with dry eye varied with age, sex, race, and residence region. Further research is needed to comprehend the underlying mechanisms, implications, and to address disparities in the diagnosis and management of dry eye., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Dietary supplement (DS) use is common and increasing among older adults, though much data available on use frequencies are from surveys and performed cross-sectionally. This paper sought to assess the frequency and pattern of dietary supplement use among older adults over time., Methods: A secondary analysis of data from the AAA LongROAD study, a longitudinal prospective cohort study of older adult drivers, using data from baseline and the first two years of follow up included a total of 2990 drivers aged 65-79 years recruited at five study sites across the US from July 2015 to March 2017. Participants underwent baseline and annual evaluations, which included a "brown bag" medication review. DS were identified and categorized according to type and key components. Prevalence and pattern of DS use over time and relationship to demographics were measured with frequency and Chi squared analyses., Results: 84% of participants took at least one dietary supplement during the 2-year study period, and 55% of participants continually reported use. DS accounted for approximately 30% of the total pharmacologic-pill burden in all years. Participants who were White non-Hispanic, female, 75-79 years of age at baseline, and on more non-supplement medications took significantly more dietary supplements (P < 0.05). Vitamin D, multivitamins, calcium, and omega-3 formulations were the most common supplements, with stable use over time. Use of individual herbal supplements and cannabis products was uncommon (< 1% participants per year)., Conclusions: DS use among older adults is common and relatively stable over time and contributes to polypharmacy. In clinical settings, providers should consider the influence of DS formulations on polypharmacy, and the associated cost, risk of medication interactions, and effect on medication compliance., (© 2024.

Background: Studies investigating the relationship between flavonoid intake and chronic kidney disease (CKD) are limited. This study investigated the association between daily flavonoid intake and CKD in US adults by using data for 2007-2008, 2009-2010, and 2017-2018 from the National Health and Nutrition Examination Survey (NHANES) database., Methods: This study employed a cross-sectional design and used data from three cycles of the continuous NHANES: 2007-2008, 2009-2010, and 2017-2018. NHANES researchers collected data related to consumption of various food and beverages from participants by employing 24-h dietary recall questionnaires. CKD is defined as an estimated glomerular filtration rate of < 60 mL/min/1.73m2 or a urine albumin-to-creatinine ratio of ≥ 30 mg/g., Results: The odds ratios (OR) for CKD risk in the second (Q2), third (Q3), and fourth (Q4) quartiles of total flavonoid intake, compared with that in the first (Q1) quartile, were 0.780 (95% CI: 0.600, 1.015), 0.741 (95% CI: 0.573, 0.957), and 0.716 (95% CI: 0.554, 0.925), respectively (with a P value for the trend of 0.040). According to the restricted cubic spline analysis, total flavonoid intake exhibited a non-linear relationship with CKD risk (P < 0.001)., Conclusion: Our findings suggest that a potential J-shaped relationship was observed between total flavonoid consumption and CKD risk, with an inflection point at 69.58 mg/d. Our study indicates that a moderate intake of flavonoids may confer renal benefits which may offer novel strategies for CKD treatment., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Liu et al.

Aims: Little is known about the enrollment practice of both Black, Indigenous and People of Color (BIPOC) and females in the US diabetes trials. We aimed to perform a chronological survey to evaluate the enrollment of BIPOC and female participants in the US diabetes randomized controlled trials (RCTs) over the past two decades., Methods: We searched databases to systematically include the US diabetes RCTs from 2000 January 1st to 2020 December 31st. Primary outcome was the adequate enrollment of both BIPOC and females, defined by the participation to prevalence ratio (PPR) > 0.8. We tested the temporal trend in adequate enrollment over time and used logistic regression analysis to explore the relationship between adequate enrollment and trial characteristics., Results: A total of 69 US diabetes trials were included for analyses, with a median BIPOC and female enrollment percentage of 29.0 % and 45.4 % respectively. There were 22 (31.9 %) trials with adequate enrollment of both BIPOC and females. No significant trend of adequate enrollment percentage of BIPOC and females over time was observed (P = 0.16). Of trial types, those with medication interventions were significantly related to decreased odds of adequate enrollment, when compared to trials with non-drug interventions (odds ratio = 0.29, 95 % confidence interval: 0.11-0.84)., Conclusions: Less than one third of the US diabetes trials adequately enrolled both BIPOC and females over the past two decades, and no temporal improvement in BIPOC and female participant enrollment was observed. These results highlight the need for more endeavors to mitigate inadequate representation regarding BIPOC and female enrollment in diabetes trials., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Research Trust of DiabetesIndia (DiabetesIndia) and National Diabetes Obesity and Cholesterol Foundation (N-DOC).

We report highly pathogenic avian influenza A(H5N1) virus in dairy cattle and cats in Kansas and Texas, United States, which reflects the continued spread of clade 2.3.4.4b viruses that entered the country in late 2021. Infected cattle experienced nonspecific illness, reduced feed intake and rumination, and an abrupt drop in milk production, but fatal systemic influenza infection developed in domestic cats fed raw (unpasteurized) colostrum and milk from affected cows. Cow-to-cow transmission appears to have occurred because infections were observed in cattle on Michigan, Idaho, and Ohio farms where avian influenza virus-infected cows were transported. Although the US Food and Drug Administration has indicated the commercial milk supply remains safe, the detection of influenza virus in unpasteurized bovine milk is a concern because of potential cross-species transmission. Continued surveillance of highly pathogenic avian influenza viruses in domestic production animals is needed to prevent cross-species and mammal-to-mammal transmission.

Background: Hyperuricemia (HUA) is a glo\bal public health problem. The etiology of HUA is complex and efficient and accurate assessment metrics are still lacking when conducting large-scale epidemiologic screening. The aim of this study was to evaluate the association of the triglyceride glucose (TyG) index, TyG-body mass index (BMI), TyG-waist-to-height ratio (WHtR) with the risk of HUA., Methods: Based on data collected from the National Health and Nutrition Examination Survey (NHANES) in the United States and the China Health and Aging Longitudinal Study (CHARLS) in China, a total of 14,286 U.S. adults and 4,620 Chinese adults were included in the analysis. The study examined the levels of TyG, TyG-BMI, TyG-WHtR, and TyG-WC. Multivariate logistic regression was utilized to investigate the relationships between these variables and hyperuricemia (HUA), separately. Additionally, the study used restricted cubic splines (RCS) to explore the linear associations of TyG, TyG-BMI, TyG-WHtR, TyG-WC, and HUA, separately., Results: The NHANES results showed that TyG [Q2, 1.58(1.26, 1.98); Q3, 2.36 (1.94, 2.88); Q4, 3.21 (2.61, 3.94)], TyG-BMI [Q2, 2.14 (1.74, 2.65); Q3, 3.38 (2.74, 4.17); Q4, 6.70 (5.55, 8.02)], TyG-WHtR [Q2, 1.92 (1.56, 2.36); Q3, 3.14 (2.56, 3.85); Q4, 6.28 (5.12, 7.69)], TyG-WC [Q2, 2.32 (1.85, 2.90); Q3, 3.51 (2.84, 4.34); Q4, 7.32 (5.95, 9.02)] were identified as risk factors for hyperuricemia (HUA). Similarly, the CHARLS results, when fully adjusted for covariates, indicated that TyG [Q4, 2.36 (1.08, 5.15)], TyG-BMI [Q3, 2.60 (1.05, 6.41); Q4, 3.70 (1.64, 8.32)], TyG-WHtR (Q4, 2.84 (1.23, 6.55), TyG-WC [Q4, 2.85 (1.23, 6.5)] were also risk factors for HUA. The predictive ability of each indicator for the risk of developing HUA was stronger in women than in men. Furthermore, there was an observed nonlinear relationship between TyG, TyG-BMI, TyG-WHtR, TyG-WC, and HUA in both the NHANES and CHARLS datasets ( P-nonlinearity < 0.05)., Conclusion: These findings suggest that TyG, TyG-BMI, TyG-WHtR and TyG-WC are associated with an increased risk of HUA. They are potential indicators for screening HUA status in the general population in China and the United States., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Gou, Dou, Tian, Chang, Zhao, Meng and Li.)

Objective: This study was designed to examine the association between physical activity (PA) and depression among adult prescription opioid users., Method: Data of adults who recently took prescription opioids were collected from NHANES 2007-2018. Participants were divided into two groups according to whether PA in each domain was ≥600 MET-min/week. According to weekly activity frequency, recreational physical activity (RPA) was divided into inactivity, insufficient activity, weekend warrior (WW), and regular activity. PHQ-9 scores ≥10 were identified as depression., Results: RPA of ≥600 MET-min/week was associated with a 40% (OR: 0.60, 95%CI: 0.38-0.96, P = 0.032) reduction in the risk of depression. Restricted Cubic Spline plots found a nonlinear dose-response relationship between RPA and depression (P = 0.045), and the turning point of depression risk was around 600 MET-min/week. There was no significant difference in the risk of depression between the WW and inactivity groups (OR: 0.65, 95%CI: 0.25-1.72, P = 0.382). The regular activity group had an 45% (OR: 0.55, 95%CI: 0.31-0.99, P = 0.046)lower risk for depression than the inactivity group., Conclusion: Only regular RPA is associated with a reduced risk of depression, and RPA showed a nonlinear dose-response relationship. The antidepressant effect of the WW is not significant., Competing Interests: Declaration of competing interest None., (Copyright © 2023. Published by Elsevier Inc.)

Thyroid cancer is the most common endocrine malignancy in the pediatric population. A recent study has revealed a recent decline in overall US thyroid cancer incidence rates. The aim of this study is to assess whether there has been a corresponding decline in incidence rates in the pediatric population. We used the Surveillance, Epidemiology, and End Results (SEER) database to analyze the pediatric thyroid cancer incidence rate. The results demonstrate that the incidence rate of pediatric thyroid cancer continued to increase from 2000 to 2018. Future studies are needed to understand how recent changes in guidelines are affecting incidence rates.

Background: Observational studies are used for estimating vaccine effectiveness under real-world conditions. The practical performance of two common approaches-cohort and test-negative designs-need to be compared for COVID-19 vaccines., Methods: We compared the cohort and test-negative designs to estimate the effectiveness of the BNT162b2 vaccine against COVID-19 outcomes using nationwide data from the United States Department of Veterans Affairs. Specifically, we (1) explicitly emulated a target trial using follow-up data and evaluated the potential for confounding using negative controls and benchmarking to a randomized trial, (2) performed case-control sampling of the cohort to confirm empirically that the same estimate is obtained, (3) further restricted the sampling to person-days with a test, and (4) implemented additional features of a test-negative design. We also compared their performance in limited datasets., Results: Estimated BNT162b2 vaccine effectiveness was similar under all four designs. Empirical results suggested limited residual confounding by healthcare-seeking behavior. Analyses in limited datasets showed evidence of residual confounding, with estimates biased downward in the cohort design and upward in the test-negative design., Conclusion: Vaccine effectiveness estimates under a cohort design with explicit target trial emulation and a test-negative design were similar when using rich information from the VA healthcare system, but diverged in opposite directions when using a limited dataset. In settings like ours with sufficient information on confounders and other key variables, the cohort design with explicit target trial emulation may be preferable as a principled approach that allows estimation of absolute risks and facilitates interpretation of effect estimates., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objectives: To assess the contemporary prevalence and decade-long trends of sleep duration, sleep disorders and trouble sleeping among adults in the United States, as well as their risk factors, from 2005 to 2018., Materials and Methods: We used National Health and Nutrition Examination Survey data to calculate the sleep duration and weighted prevalence of sleep disorders and trouble sleeping in adults aged 20 years or older. Sleep duration, sleep disorders and trouble sleeping were assessed by questionnaire., Results: A total of 27,399 people were included in the survey on sleep duration, with a weighted percentage of normal sleep (7-8 h/night) of 56.33 % (95 % CI, 53.06-59.60 %) and a weighted percentage of short sleep (5-6 h/night) of 31.73 %. In stratified descriptions, participants aged 40-49 years were more likely to sleep less than five hours, while women aged 80 years and older were more likely to sleep longer and blacks were more likely to sleep shorter. A total of 27,406 participants were included in the survey for sleep disorders. The weighted proportion of the population with sleep disorders was 8.44 % (95 % CI, 7.79-9.8 %). Independent risk factors for sleep disorders were being 40-69 years old, being white, having a high education level, smoking, having hypertension, diabetes, heart disease, and BMI ≥ 25. From 2005 to 2014, the prevalence of sleep disorders increased year by year, from 7.44 % in 2005-2006 to 10.40 % in 2013-2014 (P for Trend<0.001). A total of 38,165 participants were included in the survey on trouble sleeping. The weighted proportion of the population with troubled sleeping was 27.30 % (25.70-28.90 %). Independent risk factors for troubled sleeping were being 30-79 years old, being white, having a high education level, smoking, drinking, having hypertension, diabetes, heart disease and BMI ≥ 25. From 2005 to 2018, the prevalence of trouble sleeping increased annually, from 24.44 % in 2005-2006 to 30.58 % in 2017-2018 (P for trend<0.001)., Conclusion: Adults in the United States are likely to have abnormal sleep durations, and the prevalence of sleep disorders and troubled sleeping is on the rise., Competing Interests: Declaration of competing interest The authors have declared no conflicts of interest., (Copyright © 2023.

Introduction: Studies exploring the relationship between peripheral arterial disease (PAD), critical limb ischemia (CLI), and chronic kidney disease (CKD) and its effect on in-hospital outcomes are limited. We aimed to analyze the outcomes of patients with CKD and PAD who are admitted for CLI., Methods: We utilized the National Inpatient Sample (NIS) to capture hospitalizations for CLI from 2012 to 2020 and then identified cases with concomitant CKD. The primary outcome was mortality, and secondary outcomes were cerebrovascular accident, major bleeding, vasopressor requirement, percutaneous coronary intervention, cardiac arrest, acute respiratory failure, transfusion, length of stay, and total hospital charges. Multivariable logistic regression was performed to adjust for covariates., Results: A total of 441,245 patients with CLI were identified, of which 122,370 (27.7%) reported concomitant CKD. Patients with CKD had higher in-patient mortality (odds ratio [OR] 1.68, 95% confidence interval [CI], 1.17-1.68, p &lt; 0.001), vascular complications (OR 1.31, 95% CI, 1.17-1.48, p &lt; 0.001), acute kidney injury requiring hemodialysis (OR 3.17, 95% CI, 2.64-3.80, p &lt; 0.001), and major bleeding (OR 1.12, 95% CI, 1.05-1.19, p &lt; 0.001). Patients with CKD underwent minimally invasive endovascular therapy (31.08% vs. 36.73%, p &lt; 0.0001) and invasive procedures (14.73% vs. 23.55%, p &lt; 0.0001) less often. PAD-CLI with CKD was associated with major (20.54% vs. 16.17%, OR 1.04; p &lt; 0.0001) and minor (26.87% vs. 19.53%, OR 1.2, p &lt; 0.0001) amputations more often., Conclusion: Patients admitted for PAD-CLI with concomitant CKD have significantly higher in-hospital mortality as compared to patients without CKD. Moreover, patients with CKD and PAD-CLI are less likely to receive revascularization and more likely to undergo amputation., (© 2024 The Author(s). Published by S. Karger AG, Basel.)

Background: Limited evidence exists on the economic burden of individuals who progress from mild cognitive impairment (MCI) to Alzheimer disease and related dementia disorders (ADRD)., Objectives: To assess the all-cause health care resource utilization and costs for individuals who develop ADRD following an MCI diagnosis compared to those with stable MCI., Design: This was a retrospective cohort study from January 01, 2014, to December 31, 2019., Setting: The Merative MarketScan Commercial and Medicare Databases were used., Participants: Individuals were included if they: (1) were aged 50 years or older; (2) had ≥1 claim with an MCI diagnosis based on the International Classification of Diseases, Ninth Revision (ICD-9) code of 331.83 or the Tenth Revision (ICD-10) code of G31.84; and had continuous enrollment. Individuals were excluded if they had a diagnosis of Parkinson's disease or ADRD or prescription of ADRD medication., Measurements: Outcomes included all-cause utilization and costs per patient per year in the first 12 months following MCI diagnosis, in total and by care setting: inpatient admissions, emergency department (ED) visits, outpatient visits, and pharmacy claims., Results: Out of the total of 5185 included individuals, 1962 (37.8%) progressed to ADRD (MCI-to-ADRD subgroup) and 3223 (62.2%) did not (Stable MCI subgroup). Adjusted all-cause utilization was higher for all care settings in the MCI-to-ADRD subgroup compared with the Stable MCI subgroup. Adjusted all-cause mean total costs ($34 599 vs $24 541; mean ratio [MR], 1.41 [95% CI, 1.31-1.51]; P<.001), inpatient costs ($47 463 vs $38 004; MR, 1.25 [95% CI, 1.08-1.44]; P=.002), ED costs ($4875 vs $3863; MR, 1.26 [95% CI, 1.11-1.43]; P<.001), and outpatient costs ($16 652 vs $13 015; MR, 1.28 [95% CI, 1.20-1.37]; P<.001) were all significantly higher for the MCI-to-ADRD subgroup compared with the Stable MCI subgroup., Conclusions: Individuals who progressed from MCI to ADRD had significantly higher health care costs than individuals with stable MCI. Early identification of MCI and delaying its progression is important to improve patient and economic outcomes., Competing Interests: Feride H Frech is an employee of Eisai Inc.

Purpose: To investigate health disparities in racial and ethnic minorities with dry eye., Methods: Medical records were reviewed for demographics, socioeconomic factors, treatments, and objective dry eye parameters. Race/ethnicity was self-reported as delineated by the U.S. Census. The reference group comprised of randomly selected White patients, with number equal to the largest minority group., Results: The study included 465 patients (157 Black, 157 White, 85 Asian, and 66 Hispanic). Compared to White (3.2%) patients, larger proportion of minorities used Medicaid or lacked health insurance (Black 8.3%, P = .054; Asian 10.6%, P = .019; Hispanic 18.2%, P < .001). Black and Hispanic patients had lower estimated median household income than Whites (White $98,472, Black $75,554, P < .001; Asian $105,503, P = .088; Hispanic $86,839, P = .030). Prior to presentation, fewer minority patients received prescription treatments or procedures (White 61.8%; Black 30.6%, P < .001; Asian 43.5%, P = .006; Hispanic 43.9%, P = .014). Although at baseline visit minorities had worse mean conjunctival (White, 1.7; Black 2.2, P = .136, Asian 2.4, P = .022; Hispanic 2.6, P = .005) and corneal staining scores (White, 1.6; Black 2.5, P < .001; Asian 2.3, P = .003; Hispanic 2.4, P = .001), no differences were noted at final visit., Conclusion: Minorities presented with worse objective dry eye parameters, and less prior dry eye care. Income and health care access may not fully explain the observed undertreatment at presentation. Differential management by eye care providers and patient attitudes warrant further investigation.

Background: Providing continuous health insurance coverage during the perinatal period may increase access to and utilization of labor neuraxial analgesia. This study tested the hypothesis that implementation of the 2010 Dependent Coverage Provision of the Patient Protection and Affordable Care Act, requiring private health insurers to allow young adults to remain on their parent's plan until age 26 yr, was associated with increased labor neuraxial analgesia use., Methods: This study used a natural experiment design and birth certificate data for spontaneous vaginal deliveries in 28 U.S. states between 2009 and 2013. The intervention was the Dependent Coverage Provision, categorized into pre- and postintervention periods (January 2009 to August 2010 and September 2010 to December 2013, respectively). The exposure was women's age, categorized as exposed (21 to 25 yr) and unexposed (27 to 31 yr). The outcome was the labor neuraxial analgesia utilization rate., Results: Of the 4,515,667 birth certificates analyzed, 3,033,129 (67.2%) indicated labor neuraxial analgesia use. For women aged 21 to 25 yr, labor neuraxial analgesia utilization rates were 64.9% during the preintervention period and 68.9% during the postintervention period (difference, 4.0%; 95% CI, 3.9 to 4.2). For women aged 27 to 31 yr, labor neuraxial analgesia utilization rates were 64.9% during the preintervention period and 67.7% during the postintervention period (difference, 2.8%; 95% CI, 2.7 to 2.9). After adjustment, implementation of the Dependent Coverage Provision was associated with a 1.0% (95% CI, 0.8 to 1.2) absolute increase in labor neuraxial analgesia utilization rate among women aged 21 to 25 yr compared with women aged 27 to 31 yr. The increase was statistically significant for White and Hispanic women but not for Black and Other race and ethnicity women., Conclusions: Implementation of the Dependent Coverage Provision was associated with a statistically significant increase in labor neuraxial analgesia use, but the small effect size is unlikely of clinical significance., (Copyright © 2023 American Society of Anesthesiologists.

Background: Eclampsia is an indicator of severe maternal morbidity and can be prevented through increased prenatal care access and early prenatal care utilization. The 2014 Medicaid expansion under the Patient Protection and Affordable Care Act allowed states to expand Medicaid coverage to nonelderly adults with incomes up to 138% of the federal poverty level. Its implementation has led to a significant increase in prenatal care access and utilization., Objective: This study aimed to assess the association of Medicaid expansion under the Affordable Care Act with eclampsia incidence., Study Design: This natural experiment study was based on US birth certificate data from January 2010 to December 2018 in 16 states that expanded Medicaid in January 2014 and in 13 states that did not expand Medicaid during the study period. The outcome was eclampsia incidence, the intervention was the implementation of the Medicaid expansion, and the exposure was state expansion status. Using the interrupted time series method, we compared temporal trends in the incidence of eclampsia before and after the intervention in expansion vs non-expansion states with adjustments for patient and hospital county characteristics., Results: Of the 21,570,021 birth certificates analyzed, 11,433,862 (53.0%) were in expansion states and 12,035,159 (55.8%) were in the postintervention period. The diagnosis of eclampsia was recorded in 42,677 birth certificates or 19.8 per 10,000 (95% confidence interval, 19.6-20.0). The incidence of eclampsia was higher for Black people (29.1 per 10,000) than for White (20.7 per 10,000), Hispanic (15.3 per 10,000), and birthing people of other race and ethnicity (15.4 per 10,000). In the expansion states, the incidence of eclampsia increased during the preintervention period and decreased during the postintervention period; in the nonexpansion states, a reverse pattern was observed. A statistically significant difference was observed between expansion and nonexpansion states in temporal trends between the pre- and postintervention periods, with an overall 1.6% decrease (95% confidence interval, 1.3-1.9) in the incidence of eclampsia in expansion states compared with nonexpansion states. The results were consistent in subgroup analyses according to maternal race and ethnicity, education level (less than high school or high school and higher), parity (nulliparous or parous), delivery mode (vaginal or cesarean delivery), and poverty in the residence county (high or low)., Conclusion: Implementation of the Affordable Care Act Medicaid expansion was associated with a small statistically significant reduction in the incidence of eclampsia. Its clinical significance and cost-effectiveness remain to be determined., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Introduction: Although interest in including non-randomised studies of interventions (NRSIs) in meta-analysis of randomised controlled trials (RCTs) is growing, estimates of effectiveness obtained from NRSIs are vulnerable to greater bias than RCTs. The objectives of this study are to: (1) explore how NRSIs can be integrated into a meta-analysis of RCTs; (2) assess concordance of the evidence from non-randomised and randomised trials and explore factors associated with agreement; and (3) investigate the impact on estimates of pooled bodies of evidence when NRSIs are included., Methods and Analysis: We will conduct a systematic survey of 210 systematic reviews that include both RCTs and NRSIs, published from 2017 to 2022. We will randomly select reviews, stratified in a 1:1 ratio by Core vs non-Core clinical journals, as defined by the National Library of Medicine. Teams of paired reviewers will independently determine eligibility and abstract data using standardised, pilot-tested forms. The concordance of the evidence will be assessed by exploring agreement in the relative effect reported by NRSIs and RCT addressing the same clinical question, defined as similarity of the population, intervention/exposure, control and outcomes. We will conduct univariable and multivariable logistic regression analyses to examine the association of prespecified study characteristics with agreement in the estimates between NRSIs and RCTs. We will calculate the ratio of the relative effect estimate from NRSIs over that from RCTs, along with the corresponding 95% CI. We will use a bias-corrected meta-analysis model to investigate the influence on pooled estimates when NRSIs are included in the evidence synthesis., Ethics and Dissemination: Ethics approval is not required. The findings of this study will be disseminated through peer-reviewed publications, conference presentations and condensed summaries for clinicians, health policymakers and guideline developers regarding the design, conduct, analysis, and interpretation of meta-analysis that integrate RCTs and NRSIs., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Purpose: Predict nonhome discharge (NHD) following elective anterior cervical discectomy and fusion (ACDF) using an explainable machine learning model., Methods: 2227 patients undergoing elective ACDF from 2008 to 2019 were identified from a single institutional database. A machine learning model was trained on preoperative variables, including demographics, comorbidity indices, and levels fused. The validation technique was repeated stratified K-Fold cross validation with the area under the receiver operating curve (AUROC) statistic as the performance metric. Shapley Additive Explanation (SHAP) values were calculated to provide further explainability regarding the model's decision making., Results: The preoperative model performed with an AUROC of 0.83 ± 0.05. SHAP scores revealed the most pertinent risk factors to be age, medicare insurance, and American Society of Anesthesiology (ASA) score. Interaction analysis demonstrated that female patients over 65 with greater fusion levels were more likely to undergo NHD. Likewise, ASA demonstrated positive interaction effects with female sex, levels fused and BMI., Conclusion: We validated an explainable machine learning model for the prediction of NHD using common preoperative variables. Adding transparency is a key step towards clinical application because it demonstrates that our model's "thinking" aligns with clinical reasoning. Interactive analysis demonstrated that those of age over 65, female sex, higher ASA score, and greater fusion levels were more predisposed to NHD. Age and ASA score were similar in their predictive ability. Machine learning may be used to predict NHD, and can assist surgeons with patient counseling or early discharge planning., (© 2023.

Objective: The lifetime occurrence rate of kidney stones is 14%, making it one of the most prevalent urological conditions. Other contributing elements, such as obesity, diabetes, diet, and heredity, are also taken into account. Our research sought to explore the potential link between high visceral fat scores (METS-VF) and the occurrence of kidney stones, as a means of understanding how to prevent them., Methods: This research utilized data from the National Health and Nutrition Examination Survey (NHANES), mirroring the demographics of the United States. We carried out an in-depth analysis of the connection between METS-VF and kidney stones, based on data from 29,246 participants in the National Health and Nutrition Examination Survey spanning 2007 to 2018, involving logistic regression, segmentation, and dose-response curve analysis., Results: Our study of 29,246 potential participants found that METS-VF was positively associated with the prevalence and progression of kidney stones. After subgroup analysis by gender, race, blood pressure, and blood glucose, our results showed that the ORs for METS-VF and kidney stones were (1.49, 1.44) in males and females, respectively; while in Mexicans, whites, blacks, and In other populations, the OR values were (1.33, 1.43, 1.54, 1.86); in hypertensive and normal populations, the OR values were (1.23, 1.48); in diabetic patients and normoglycemic patients were (1.36,1.43). This proves that it works for all groups of people., Summary: Our studies demonstrate a strong connection between METS-FV and the emergence of kidney stones. It would be beneficial to investigate METS-VF as a marker for kidney stone development and progression in light of these findings., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Guo, Li, Chen, Fan, Sun, Hao and Wang.)

Background: This study is aimed at evaluating the diagnostic efficacy and unnecessary fine-needle aspiration (FNA) rate of ultrasound-based risk stratification for thyroid nodules in the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) and the American Thyroid Association (ATA) risk stratification systems., Methods: Children and adolescents with pathology confirmed thyroid nodules were retrospectively included in this study. A total of 217 thyroid nodules from multicenter of Union Medical College Hospital, China Japan Friendship Hospital and Civil Aviation Hospital were included, the diagnostic efficiency and unnecessary FNA rate were calculated according to ACR and ATA guidelines., Results: Among all thyroid nodules, 139 nodules were malignant, and 78 nodules were benign. Choosing ATA high suspicion and ACR TI-RADS TR5 as benign and malignant cut-off points, the area under the curve and sensitivity of ATA were higher than ACR (AUC: 0.887 vs 0.840, p=0.0037; sensitivity 81.3% vs 71.0%, P <0.049;specificity 96.2% vs 97.4%, p=1.000;specificity both 85.9%); choosing high/intermediate suspicion in ATA and ACR TR4/5 as benign and malignant cut-off points, the two guidelines demonstrated similar diagnostic efficacy (AUC:0.890 vs 0.897, p=0.6038, sensitivity 92.1% vs 93.5%, P =0.817;specificity both 85.9%, p=1.000). The inappropriate FNA rate of ACR guideline was relatively lower (ATA 42.9% vs ACR 27.2%, P <0.001). If ACR TI-RADS TR5 nodules less than 1.0cm were included in the FNA indication, the unnecessary biopsy rate would be further reduced to 17.9%., Conclusion: This study indicated that both ATA and ACR TI-RADS risk stratification systems could provide a feasible differential diagnosis of benign and malignant thyroid nodules, while the ACR risk stratification system demonstrates a lower rate of inappropriate FNA rate. In addition, it was necessary to further study the minimum FNA threshold of thyroid nodules in Children and adolescents in order to reduce the missed biopsy rate of malignant nodules., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Li, Zhang, Liu and Xiong.)

Aim: To evaluate the utility of magnetic resonance imaging (MRI) and magnetic resonance sialography (MRS) for diagnosis of primary Sjögren syndrome (pSS) singly or integrated with 2016 American College of Rheumatology (ACR)/European League Against Rheumatic Diseases (EULAR) classification criteria., Methods: The diagnostic efficiencies of MRI, MRS, and labial salivary gland biopsy (LSGB) were evaluated. The prediction model was established by multivariate analysis. Finally, performance of the ACR/EULAR criteria was evaluated after addition of MRI + MRS or replacement of original items by MRI + MRS., Results: The combined use of LSGB + MRI + MRS provided the greatest diagnostic value. MRI and MRS grade had positive correlations with disease duration and pathological grade of the labial gland (both P < 0.001). MRI and MRS grade had positive correlations with xerostomia severity and negative correlations with unstimulated salivary flow rate (both P < 0.001). The consistency of MRI grade and MRS grade in the diagnosis of parotid gland lesions was poor (κ = 0.253, P < 0.001). The diagnostic efficiency of our prediction model (AUC 0.906) was similar to that of criteria from the ACR/EULAR (AUC 0.930). Adding MRI + MRS to the ACR/EULAR criteria improved the sensitivity (92.3% vs 90.8%), whereas the specificity remained the same (88.9% vs 89.1%). Replacing LSGB by MRI + MRS in the ACR/EULAR criteria decreased both sensitivity and specificity (88.1% vs 90.8% and 86.4% vs 89.1%, respectively)., Conclusion: The combined application of MRI and MRS has ideal clinical application value in the diagnosis of early-stage pSS. Validity of the ACR/EULAR criteria remains high after incorporation of MRI + MRS., (© 2022 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Extracellular vesicles (EVs) carry diverse bioactive components including nucleic acids, proteins, lipids and metabolites that play versatile roles in intercellular and interorgan communication. The capability to modulate their stability, tissue-specific targeting and cargo render EVs as promising nanotherapeutics for treating heart, lung, blood and sleep (HLBS) diseases. However, current limitations in large-scale manufacturing of therapeutic-grade EVs, and knowledge gaps in EV biogenesis and heterogeneity pose significant challenges in their clinical application as diagnostics or therapeutics for HLBS diseases. To address these challenges, a strategic workshop with multidisciplinary experts in EV biology and U.S. Food and Drug Administration (USFDA) officials was convened by the National Heart, Lung and Blood Institute. The presentations and discussions were focused on summarizing the current state of science and technology for engineering therapeutic EVs for HLBS diseases, identifying critical knowledge gaps and regulatory challenges and suggesting potential solutions to promulgate translation of therapeutic EVs to the clinic. Benchmarks to meet the critical quality attributes set by the USFDA for other cell-based therapeutics were discussed. Development of novel strategies and approaches for scaling-up EV production and the quality control/quality analysis (QC/QA) of EV-based therapeutics were recognized as the necessary milestones for future investigations., (© 2023 The Authors.

Objectives: To explore trends in risk factor control (hypertension, diabetes mellitus, hyperlipidaemia) in patients with gout and medication use among those whose risk factor control targets were not achieved., Methods: We used the data from National Health and Nutrition Examination Survey (NHANES) between 2007-2008 and 2017-2018 for analyses. The study samples were weighted so that they could be representative of the non-institutionalized US population. We conducted a cross-sectional analysis to assess trends in risk factor control and medication use, and employed logistic regression analyses to explore patient characteristics associated with risk factor control., Results: The prevalence of participants in whom blood pressure control target was achieved decreased from 64.6% in 2007-2008 to 55.3% in 2017-2018 (P-value for trend = 0.03). The percentage of participants whose glycaemic, lipid or all three risk factor control targets were achieved remained stable temporally (P > 0.05). Some patient characteristics were significantly related to risk factor control, including age 45-64, age ≥65, Asian Americans, non-Hispanic Blacks, higher family income, and being overweight and obese. A trend towards increased use of glucose-lowering medication was found (from 71.0% in 2007-2008 to 94.7% in 2017-2018, P < 0.01), while the prevalence of taking blood pressure-lowering and lipid-lowering medications remained stable (P > 0.05)., Conclusion: Based on NHANES data, a significant trend towards decreased blood pressure control was observed in patients with gout, while glycaemic and lipid control levelled off. These findings emphasize that more endeavours are needed to improve management of cardiovascular risk factors in patients with gout., (© The Author(s) 2022.

Meningioma is the most common primary central nervous system tumor, and its incidence is increasing. A systematic epidemiological and clinical analysis is required to better estimate its public health impact and understand its prognostic factors. Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2018 for all types of meningiomas without an age restriction. Age-adjusted incidence rates (IRs) and 95% confidence intervals were estimated according to sex, age, race, ethnicity, and tumor location. Kaplan-Meier analysis and multivariate Cox proportional hazard models were used to analyze the overall survival (OS). The competing risk regression model of Fine-Gray was used to analyze cause-specific survival. Data from a total of 109 660 meningioma patients were analyzed. A majority of patients were older than 60 years, and only 0.41% of patients were 0-19 years. The meningioma IRs were higher in females, Black, and non-Hispanic patients than in males, White, and Hispanic patients, respectively, and IRs increased with age. The ratio of IRs for females to males was 2.1 and also increased with age, peaking at 3.6 in the 45-49-year-old group. Older and male patients with all types of meningiomas, Black patients with benign and borderline meningiomas, and patients with larger borderline and malignant meningiomas showed poorer prognosis. For all meningioma types, surgical resection improved survival. The reported incidence rates and survival trends covered all demographics and subtypes of meningiomas. Older age, male sex, Black race, and tumor size may be important prognostic factors for meningioma cases, and tumor resection can substantially improve survival among meningioma patients., (© 2022 UICC.)

Osteoporosis constitutes a significant public health risk. An estimated 10.2 million adults in the United States >50 years of age have osteoporosis, a systemic condition that weakens the bones increasing the susceptibility for fractures. Approximately one-half of women and nearly one-third of men >50 years of age will sustain an osteoporotic fracture. These fractures are associated with a decrease in quality of life, diminished physical function, and reduced independence. Dual-energy X-ray absorptiometry (DXA) is the primary imaging modality used to screen for osteoporosis in women >65 years of age and men >70 years of age. DXA may be used in patients <65 years of age to evaluate bone mass density if there are additional risk factors. In certain situations, vertebral fracture assessment and trabecular bone score may further predict fracture risk, particularly in patients who are not yet osteoporotic but are in the range of osteopenia. Quantitative CT is useful in patients with advanced degenerative changes in the spine. Given the proven efficacy of pharmacologic therapy, the role of imaging to appropriately identify and monitor high-risk individuals is critical in substantially reducing osteoporosis-associated morbidity and mortality, and reducing the considerable cost to the health care system. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation., (Copyright © 2022 American College of Radiology.

Background: Epidemiological evidence on different classes of antihypertensives and risks of Alzheimer's disease and related dementias (ADRD) is inconclusive and limited. This study examined the association between antihypertensive use (including therapy type and antihypertensive class) and ADRD diagnoses among older adults with hypertension., Methods: A retrospective, cross-sectional study was conducted, involving 539 individuals aged ≥ 65 years who used antihypertensives and had ADRD diagnosis selected from 2013 to 2018 Medical Expenditure Panel Survey (MEPS) data. The predictors were therapy type (monotherapy or polytherapy) and class of antihypertensives defined using Multum Lexicon therapeutic classification (with calcium channel blockers [CCBs] as the reference group). Weighted logistic regression was used to assess the relationships of therapy type and class of antihypertensives use with ADRD diagnosis, adjusting for sociodemographic characteristics and health status., Results: We found no significant difference between monotherapy and polytherapy on the odds of ADRD diagnosis. As to monotherapy, those who used angiotensin-converting enzyme inhibitors (ACEIs) had significantly lower odds of developing AD compared to those who used CCBs (OR 0.36, 95 % CI 0.13-0.99)., Conclusions: Findings of the study suggest the need for evidence-based drug therapy to manage hypertension in later adulthood and warrant further investigation into the mechanism underlying the protective effect of antihypertensives, particularly ACEIs, against the development of AD among older adults with hypertension., (© 2022.

Background: Since human monkeypox was reported, many related literatures have been published. This study aimed to evaluate the research hotspots and future development trends of human monkeypox by a bibliometric analysis, to analyze the preventive and control measures of various countries in response to human monkeypox outbreaks., Methods: The Web of Science Core Collection database was searched for all monkeypox related literature published from 1975 to 2022, and the search strategy was "TS = monkeypox." Bibliometric analysis was performed using VOSviewer software based on retrieval data. Contribution metric methods and visualization were used to analyze the top issues in the field of human monkeypox., Results: From 1975 to 2022, a total of 1,068 monkeypox research papers were included, of which American researchers published 663 papers, and it was also the country that participated in the most international cooperation. Centers for Disease Control Prevention USA is the most prolific institution and a leader in research collaborations. The Journal of Virology has the largest number of published papers on monkeypox. In addition, Damon Inger K has made significant contributions to monkeypox research, with both the most published and the most citation. A total of 2,847 keywords were identified, four top topics were obtained through cluster analysis: (1) human monkeypox epidemiology and species research. (2) human monkeypox virus vaccine and experimental research. (3) human monkeypox disease diagnosis and treatment studies. (4) human monkeypox disease prevention and immunization studies. To curb the spread, regions or countries have developed and implemented detailed managements. The prevention and control measures focus on the isolation of suspected or confirmed patients, the investigation and tracking of the source of the disease, the disposal of pollutants, vaccination and the protection of health workers., Conclusions: The number of human monkeypox literature has grown since 2003. Infection, vaccine and efficacy were the top topic over the past 47 years while the contact tracing, testing, surveillance and vaccination have been the major concerns since the human monkeypox outbreak in May 2022. The treatment and management of human monkeypox deserves further attention., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Lin, Li, Zhong, Zeng, Liu and Chen.)

Objective: To describe the clinical features and disease course of COVID-19 in veterans with spinal cord injury (SCI)., Design: Case series of consecutive veterans with SCI treated at a single center., Setting: SCI Unit at an urban Veterans Administration hospital at the epicenter of the COVID-19 pandemic in the US., Participants: Seven SCI veterans with confirmed COVID-19 infection by PCR; all veterans were male, mean age was 60.6. Five had cervical level of injury, and five had complete injury (AIS A). Six veterans had a BMI &gt; 22; three had chronic obstructive pulmonary disease; three had chronic kidney disease., Interventions: None., Outcome Measures: Presence of co-morbidities, diagnostic values, and clinical findings., Results: Each case presented differently; the most common presenting sign was fever. In the three individuals with critical and fatal infection, pre-existing comorbidities were more common and inflammatory markers were markedly elevated., Conclusion: Level and completeness of SCI did not appear to correlate with COVID-19 severity, as mild and asymptomatic illness was noted in persons with high grade SCI. As has been shown to be the case in the general population, pre-existing comorbidities are the most reliable predictors of severe SARS-CoV-2 infection currently available for persons with chronic SCI. Contrary to concerns that SCI may mask the cardinal signs of COVID-19, such as fever and cough, by way of compromised thermoregulation and thoracoabdominal musculature, such signs were common in our series. To facilitate early detection, prompt treatment, and minimized viral spread, the implementation of preventive strategies by SCI units is recommended.

Racial discrimination has intensified in the U.S. during the COVID-19 pandemic, but how it disrupted healthcare is largely unknown. This study investigates the association of racial discrimination with delaying or forgoing care during the pandemic based on data from a nationally representative survey, the Health, Ethnicity and Pandemic (HEAP) study (n = 2552) conducted in October 2020 with Asians, Hispanics and non-Hispanic Blacks oversampled. Racial discrimination during the pandemic was assessed in three domains: experienced racial discrimination, race-related cyberbullying, and Coronavirus racial bias beliefs. Respondents answered whether they had delayed or forgone any type of healthcare due to the pandemic. Overall, 63.7% of respondents reported delaying or forgoing any healthcare during the pandemic. About 20.3% East/Southeast Asians, 18.6% non-Hispanic Blacks and 15.9% Hispanics reported experiences of racial discrimination, compared with 2.8% of non-Hispanic Whites. Experienced racial discrimination was associated with delaying/forgoing care among non-Hispanic Blacks (Adjusted odds ratios[AOR] = 4.58, 95% confidence interval[CI]: 2.22-9.45), Hispanics (AOR = 3.88, 95%CI: 1.51-9.98), and East/Southeast Asians (AOR = 2.14, 95%CI: 1.22-3.77). Experiencing race-related cyberbullying was significantly associated with delaying/forgoing care among non-Hispanic Blacks (AOR = 1.34, 95%CI: 1.02-1.77) and East/Southeast Asians (AOR = 1.51, 95%CI: 1.19-1.90). Coronavirus racial bias was significantly associated with delaying/forgoing care among East/Southeast Asians (AOR = 1.55, 95%CI: 1.16-2.07). The three domains of racial discrimination were consistently associated with delayed or forgone health care among East/Southeast Asians during the COVID-19 pandemic; some of the associations were also seen among non-Hispanic Blacks and Hispanics. These results demonstrate that addressing racism is important for reducing disparities in healthcare delivery during the pandemic and beyond., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background and Aims: The American Society for Gastrointestinal Endoscopy (ASGE) has developed a complexity-grading system for endoscopic retrograde cholangiopancreatography (ERCP) to predict technical success and adverse events. This study aimed to assess the association between the degree of difficulty for ERCP and the rates of success and adverse event, in turn demonstrating the validity and practicality of this system., Methods: ERCP procedures performed in the First Affiliated Hospital of Nanchang University from January 2011 to December 2020 were retrospectively reviewed. Procedural success and adverse events were recorded based on difficulty level according to the ASGE-grading system., Results: A total of 20,652 ERCP procedures performed during the study period were analyzed, including 1908 procedures considered grade 1(9.2%), 10,170 procedures considered grade 2 (49.2%), 7764 procedures considered grade 3 (37.6%), 810 procedures considered grade 4 (3.9%). The overall success rate increased from 92.8% in 2011-2015 to 94.0% in 2016-2020, while the distribution of procedures and the incidence of complications showed little variation. The success rate revealed a significantly decreasing trend with increasing difficulty (ranging from 55.6 to 98.6%), mainly for biliary diseases. In addition, the difficulty scale was not associated with any differences in the rate of adverse event, except for the pancreatitis for grade 1 procedures, which had a low incidence., Conclusions: The ASGE-grading system can help predict the success rate of ERCP procedures but showed poor performance in predicting adverse events. Further exploration may be required to improve the grading system by adjusting or including certain clinical parameters, and to validate the system for extrapolation to other endoscopy units., (© 2022.

Background: Utilization of extracorporeal membrane oxygenation (ECMO) for adult critically ill patients is increasing, but data in obstetric cohorts are scant. This study analyzed ECMO utilization and maternal outcomes in obstetric patients in the United States., Methods: Data were abstracted from the 1999-2014 National Inpatient Sample (NIS), a 20% US national representative sample. ECMO hospitalizations (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 39.65) in patients ≥15 years of age were categorized into obstetric ECMO and nonobstetric ECMO. Obstetric patients included 4 categories: (1) loss or termination of pregnancy, (2) delivery (term or preterm), (3) postdelivery hospitalization, and (4) pregnancy without an obstetrical outcome. Possible underlying causes for obstetric ECMO were identified by analysis of ICD-9-CM codes in individual records. In-hospital death was abstracted from the NIS, and ECMO complications were identified using ICD-9-CM algorithms. Statistical significance in time-effect was assessed using weighted regression models., Results: During the 16-year study period, 20,454 adult ECMO cases were identified, of which 331 occurred in obstetric patients (1.6%; 95% confidence interval [CI], 1.4-1.8). Obstetric ECMO utilization rate was 4.7 per million obstetric discharges (95% CI, 4.2-5.2). The top 3 possible indications were sepsis (22.1%), cardiomyopathy (16.6%), and aspiration pneumonia (9.7%). Obstetric ECMO utilization rate increased significantly during the study period from 1.1 per million obstetric discharges in 1999-2002 (95% CI, 0.6-1.7) to 11.2 in 2011-2014 (95% CI, 9.6-12.9), corresponding to a 144.7% increase per 4-year period (95% CI, 115.3-178.1). Compared with nonobstetric ECMO, obstetric ECMO was associated with decreased in-hospital all-cause mortality (adjusted odds ratio [aOR] 0.78; 95% CI, 0.66-0.93). In-hospital all-cause mortality for obstetric ECMO decreased from 73.7% in 1999-2002 (95% CI, 48.8-90.8) to 31.9% in 2011-2014 (95% CI, 25.2-39.1), corresponding to a 26.1% decrease per 4-year period (95% CI, 10.1-39.3). Compared with nonobstetric ECMO, obstetric ECMO was associated with significantly increased risk of both venous thromboembolism without associated pulmonary embolism (aOR 1.83; 95% CI, 1.06-3.15) and of nontraumatic hemoperitoneum (aOR 4.32; 95% CI, 2.41-7.74)., Conclusions: During the study period, obstetric ECMO utilization has increased significantly and maternal prognosis improved., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 International Anesthesia Research Society.)

Objective: The purpose of this study was to examine whether the METS-IR index is associated with kidney stones in American adults., Method: Participants from the National Health and Nutrition Examination Survey (NHANES) database from 2007-2018 were selected for logistic regression analysis, subgroup analyses, and the calculation of dose-response curves to assess the association between the METS-IR index and the incidence of kidney stones., Result: This study enrolled 30,612 adults aged >20 years, 2901 of whom self-reported having had kidney stones in the past. And, after controlling for potential confounders, each unit increase in the METS-IR index was linked with a 1.23 percent rise in kidney stone incidence (OR= 1.0123, 95% CI: 1.0092 - 1.0155), with stratified analysis indicating that this was true in all subgroups. Between all groups, an elevated METS-IR index was related to kidney stone formation, and the dose-response curve revealed a positive non-linear connection between METS-IR index and kidney stone risk, with a threshold effect analysis revealing an inflection point value of 50.8314., Conclusion: Higher METS-IR index is associated with the occurrence of kidney stones,and while no causative association can be shown, this is cause for concern., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Shen, Chen, Chen, Liang, Li and Hao.)

Older adults who are Asian American and Pacific Islander (AAPI) represent one of the fastest growing populations in the United States and face a significant burden of Alzheimer's disease and related dementias (ADRD). Little is known about ADRD among AAPI subgroups. The current study aimed to: (a) explore perceptions and beliefs of memory loss and dementia among Korean, Samoan, Cambodian, and Chinese older adults in the United States; and (b) identify culturally relevant facilitators and barriers of participation in a brain health program among four AAPI subgroups. Seven focus groups comprising 14 Cambodian, 21 Chinese, 14 Korean, and 13 Samoan older adults were conducted. Data were analyzed using inductive and indigenous coding approaches. Similar and unique perceptions and experiences related to memory loss were identified. Future research could include developing and testing culturally tailored and language congruent strategies regarding ADRD education and resources to facilitate ADRD early detection among AAPI older adults.

Recent research indicates that children with autism are at increased risk of maltreatment. We examined news media reports on homicide incidents involving children with autism as victims in the United States between 2000 and 2019. Of the 52 victims studied, 47 (90.4%) were male. Age of victims ranged from 2 to 20 years (mean = 10.4 ± 5.3 years). Parents and other caregivers accounted for 63.5% and 13.5% of the perpetrators, respectively. The leading injury mechanism was gunshot wounds (23.1%), followed by drowning (19.2%), and suffocation, strangulation, or asphyxiation (19.2%). The most commonly cited contributing factor (47.1%) was overwhelming stress from caring for the autistic child. These results underscore the importance of supporting services for caregivers of children with autism., (© 2021.

Introduction: Anti-Black racism has strong roots in American health care and medical education. While curricula on social determinants of health are increasingly common in medical training, curricula directly addressing anti-Black racism are limited. Existing frameworks like the Presence 5 framework for humanism in medicine can be adapted to develop a novel workshop that promotes anti-racism communication., Methods: We performed a literature review of anti-racism collections and categorized anti-racism communication practices using the Presence 5 framework to develop the Presence 5 for Racial Justice Workshop. Implementation included an introductory didactic, a small-group discussion, and a large-group debrief. Participants evaluated the workshop via an online survey, and we analyzed the resulting qualitative feedback., Results: A total of 17 participants took part in two workshops, with nine of the participants responding to the evaluation survey. Themes that emerged from survey responses included strengths of and improvements for the workshop structure (protected time for anti-racism discussion, dialogue between learners and faculty) and content (specific phrases and language, practicing self-reflection)., Discussion: The workshop provides participants with a semistructured discussion around the five anti-racism communication practices. Barriers to implementation include incorporating the workshop into existing curricula and ensuring diverse learners. Barriers to evaluating the workshop include the low survey response rate. Recommendations to improve the workshop include using case-based discussion and varying the workshop structure according to institutional needs. Next steps include an implementation study to evaluate the acceptability, feasibility, and effectiveness of the workshop., (© 2022 Shankar et al.)

Objective: To synthesize the empirical research evidence about the association between Medicaid expansion under the Affordable Care Act (ACA) and increasing perinatal care access and utilization among low-income women., Data Sources: We searched MEDLINE through PubMed (1966-present), EMBASE (Ovid), the Cumulative Index to Nursing and Allied Health (1982-present), PAIS Index (ProQuest), Web of Science (1900-present), and the Cochrane Central Register of Controlled Trials. Our review focuses on the association between Medicaid expansion under the ACA and perinatal care access and utilization, which cannot be subjected to randomized controlled trials, therefore ClinicalTrials.gov was not included in our search., Methods of Study Selection: A comprehensive search of the research literature was performed using Covidence. Studies were eligible if they were based on population data and research designs ensuring that the exposure (ie, Medicaid expansion under the ACA) preceded the perinatal care access or utilization outcome, had an appropriate comparison group, presented quantitative data, and examined pregnant or postpartum women. The search in six bibliographic databases returned 1,243 records, with 855 abstracts reviewed, 34 full-text articles screened for eligibility, and nine eligible studies included in the systematic review., Tabulation, Integration, and Results: Stata 16 software was used to generate summary estimates, forest plots, funnel plots, and heterogeneity statistics. Random effects modeling based on pooled data revealed that Medicaid expansion was associated with a 6.1% increase in Medicaid enrollment for pregnant women (95% CI 1.3-10.9%) and a 3.3% increase in perinatal care utilization (95% CI 0.2-6.3%)., Conclusion: Medicaid expansion under the ACA is associated with a modest and statistically significant increase in perinatal care access and utilization among low-income women., Competing Interests: Financial Disclosure The authors did not report any potential conflicts of interest., (Copyright © 2022 by the American College of Obstetricians and Gynecologists.

Background: This study is aimed at evaluating the diagnostic efficacy of ultrasound-based risk stratification for thyroid nodules in the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) and the American Thyroid Association (ATA) risk stratification systems., Methods: 286 patients with thyroid cancer were included in the tumor group, with 259 nontumor cases included in the nontumor group. The ACR TI-RADS and ATA risk stratification systems assessed all thyroid nodules for malignant risks. The diagnostic effect of ACR and ATA risk stratification system for thyroid nodules was evaluated by receiver operating characteristic (ROC) analysis using postoperative pathological diagnosis as the gold standard., Results: The distributions and mean scores of ACR and ATA rating risk stratification were significantly different between the tumor and nontumor groups. The lesion diameter > 1 cm subgroup had higher malignant ultrasound feature rates detected and ACR and ATA scores. A significant difference was not found in the ACR and ATA scores between patients with or without Hashimoto's disease. The area under the receiver operating curve (AUC) for the ACR TI-RADS and the ATA systems was 0.891 and 0.896, respectively. The ACR had better specificity (0.90) while the ATA system had higher sensitivity (0.92), with both scenarios having almost the same overall diagnostic accuracy (0.84)., Conclusion: Both the ACR TI-RADS and the ATA risk stratification systems provide a clinically feasible thyroid malignant risk classification, with high thyroid nodule malignant risk diagnostic efficacy., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2022 Fei Chen et al.)

Background: In the United States, New York State's health care system experienced unprecedented stress as an early epicenter of the coronavirus disease 2019 (COVID-19) pandemic. This study aims to assess the level of hopelessness in New York State physicians working on the frontlines during the first wave of the COVID-19 outbreak., Methods: A confidential online survey sent to New York State health care workers by the state health commissioner's office was used to gather demographic and hopelessness data as captured by a brief Hopelessness Scale. Adjusted linear regression models were used to assess the associations of physician age, sex, and number of triage decisions made, with level of hopelessness., Results: In total, 1330 physicians were included, of whom 684 were male (51.4%). Their average age was 52.4 years (SD=12.7), with the majority of respondents aged 50 years and older (55.2%). Almost half of the physician respondents (46.3%) worked directly with COVID-19 patients, and 163 (12.3%) were involved in COVID-19-related triage decisions. On adjusted analysis, physicians aged 40 to 49 years had significantly higher levels of hopelessness compared with those aged 50 years or more (μ=0.441, SD=0.152, P=0.004). Those involved in 1 to 5 COVID-19-related triage decisions had a significantly lower mean hopelessness score (μ=-0.572, SD=0.208, P=0.006) compared with physicians involved in none of these decisions., Conclusion: Self-reported hopelessness was significantly higher among physicians aged 40 to 49 years and those who had not yet been involved in a life or death triage decision. Further work is needed to identify strategies to support physicians at high risk for adverse mental health outcomes during public health emergencies such as the COVID-19 pandemic., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

Introduction: In the past 22 years, a large number of publications have reported that liver kinase B1 (LKB1) can regulate a variety of cellular processes and play an important role in many diseases. However, there is no systematic bibliometric analysis on the publications of LKB1 to reveal the research hotspots and future direction., Methods: Publications were retrieved from the Web of Science Core Collection (WoSCC), Scopus, and PubMed databases. CiteSpace and VOSviewer were used to analysis the top countries, institutions, authors, source journals, discipline categories, references, and keywords., Results: In the past 22 years, the number of LKB1 publications has increased gradually by year. The country, institution, author, journals that have published the most articles and cited the most frequently were the United States, Harvard University, Prof. Benoit Viollet, Journal of Biochemistry and Plos One. The focused research hotspot was the molecular functions of LKB1. The emerging hotspots and future trends are the clinical studies about LKB1 and co-mutated genes as biomarkers in tumors, especially in lung adenocarcinoma., Conclusions: Our research could provide knowledge base, frontiers, emerging hotspots and future trends associated with LKB1 for researchers in this field, and contribute to finding potential cooperation possibilities., Competing Interests: The authors have declared that no competing interests exist.

Objectives: The COVID-19 pandemic has resulted in an enormous burden on population health and the economy around the world. Although most cities in the United States have reopened their economies from previous lockdowns, it was not clear how the magnitude of different control measures-such as face mask use and social distancing-may affect the timing of reopening the economy for a local region. This study aimed to investigate the relationship between reopening dates and control measures and identify the conditions under which a city can be reopened safely., Study Design: This was a mathematical modeling study., Methods: We developed a dynamic compartment model to capture the transmission dynamics of COVID-19 in New York City. We estimated model parameters from local COVID-19 data. We conducted three sets of policy simulations to investigate how different reopening dates and magnitudes of control measures would affect the COVID-19 epidemic., Results: The model estimated that maintaining social contact at 80% of the prepandemic level and a 50% face mask usage would prevent a major surge of COVID-19 after reopening. If social distancing were completely relaxed after reopening, face mask usage would need to be maintained at nearly 80% to prevent a major surge., Conclusions: Adherence to social distancing and increased face mask usage are keys to prevent a major surge after a city reopens its economy. The findings from our study can help policymakers identify the conditions under which a city can be reopened safely., (Copyright © 2021 The Royal Society for Public Health. Published by Elsevier Ltd.

Background: The joint effects of sex, age, body mass index (BMI) and race on hypertension have not been fully addressed. Herein, we carried out this study aiming to investigate the possible effects of the interaction of sex, age, BMI and race on risk of hypertension., Methods: By using the data of a sample-adjusted 2656 women and 2515 men in American National Health and Nutrition Examination Survey 2015-16, we analyzed the interaction of sex, age, BMI and race by logistic regression models, followed by strata-specific analyses. Hypertension was defined as a systolic blood pressure ≥130 mmHg/diastolic blood pressure ≥80 mmHg or taking anti-hypertensive medication., Results: A total of 5171 participants were included in analysis, and the prevalence of hypertension was 53.68%. The interactive effect of sex and age, BMI and age, race and age were statistically significant on hypertension. Strata-specific analyses showed that female at 40 years and above were positively associated with hypertension than those at 20-39 years. The associations also persistence in male. The risk estimates for age ≥40 on hypertension were consistently positive across all overweight/obesity and race groups. The effect was most prominent among overweight populations aged 60-80 years and Other Hispanic aged 40 years and above., Conclusion: There exists interactive effect of sex and age, BMI and age, race and age on hypertension in American population. The effect of age on hypertension was more prominent in female, overweight populations and Other Hispanic populations. Differences in age, BMI and race should be considered when providing corresponding antihypertensive measures., (© The Author(s) 2021.

Background: Metabolic-associated fatty liver disease (MAFLD) is highly prevalent in type 2 diabetes mellitus (T2DM) patients and can rapidly progress to steatohepatitis, liver fibrosis, and hepatocellular carcinoma (HCC). Accurate evaluation and proper management of MAFLD can help prevent adverse liver outcomes. Here we evaluated the precision of the FibroTouch (FT) in the staging of liver steatosis and fibrosis in patients with MAFLD combined with T2DM using two indicators: controlled attenuation parameter (CAP) and liver stiffness measurement (LSM)., Methods: Eighty-five adult MAFLD combined with T2DM patients were selected at our center from July 2016 to July 2019 and underwent liver puncture biopsy for histopathology and the FT assay simultaneously. Two blinded pathologists independently reviewed the samples. The severity of fatty liver was classified using two scoring systems: the nonalcoholic fatty liver disease activity score (NAS) and the fibrosis score. Scores were then assessed following the Pathology Working Group of the NASH Clinical Research Network of the National Institutes of Health. Similarly, the severity of nonalcoholic steatohepatitis (NASH) was classified using the European Steatosis Activity Fibrosis (SAF) system. The FT assay was applied to obtain the LSM and the CAP. FT accuracy in diagnosing steatosis and fibrosis was determined by the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUROC)., Results: Using biopsy analysis as the gold standard, the AUROCs and cutoff values of CAP in diagnosing liver steatosis were as follows: 0.84 (95% CI: 0.67-1.01) and 278 dB/m for S ≥ S1, 0.88 (95% CI: 0.81-0.95) and 305 dB/m for S ≥ S2, 0.89 (95% CI: 0.82-0.95) and 307 dB/m for S ≥ S3. The AUROCs and cutoff values of LSM in diagnosing liver fibrosis were as follows: 0.76 (95% CI: 0.66-0.86) for F ≥ F2, 0.81 (95% CI: 0.71-0.91) and 13.8 kPa for F ≥ F3, 0.92 (95% CI: 0.85-1.00) and 20.1 kPa for F ≥ F4., Conclusions: In patients of MAFLD with T2DM, CAP and LSM obtained by FT are highly accurate in assess liver steatosis and fibrosis, respectively, with AUROC values ranging from 0.76 to 0.92.

Vaccine uptake is critical for mitigating the impact of COVID-19 in the United States, but structural inequities pose a serious threat to progress. Racial disparities in vaccination persist despite the increased availability of vaccines. We ask what factors are associated with such disparities. We combine data from state, federal, and other sources to estimate the relationship between social determinants of health and racial disparities in COVID-19 vaccinations at the county level. Analyzing vaccination data from 19 April 2021, when nearly half of the US adult population was at least partially vaccinated, we find associations between racial disparities in COVID-19 vaccination and median income (negative), disparity in high school education (positive), and vote share for the Republican party in the 2020 presidential election (negative), while vaccine hesitancy is not related to disparities. We examine differences in associations for COVID-19 vaccine uptake as compared with influenza vaccine. Key differences include an amplified role for socioeconomic privilege factors and political ideology, reflective of the unique societal context in which the pandemic has unfolded., Competing Interests: The authors declare no competing interest., (Copyright © 2021 the Author(s).

Background: Air pollution may be associated with elevated dementia risk. Prior research has limitations that may affect reliability, and no studies have evaluated this question in a population-based cohort of men and women in the United States., Objectives: We evaluated the association between time-varying, 10-y average fine particulate matter ( PM 2.5 ) exposure and hazard of all-cause dementia. An additional goal was to understand how to adequately control for age and calendar-time-related confounding through choice of the time axis and covariate adjustment., Methods: Using the Adult Changes in Thought (ACT) population-based prospective cohort study in Seattle, we linked spatiotemporal model-based PM 2.5 exposures to participant addresses from 1978 to 2018. Dementia diagnoses were made using high-quality, standardized, consensus-based protocols at biennial follow-ups. We conducted multivariable Cox proportional hazards regression to evaluate the association between time-varying, 10-y average PM 2.5 exposure and time to event in a model with age as the time axis, stratified by apolipoprotein E (APOE) genotype, and adjusted for sex, education, race, neighborhood median household income, and calendar time. Alternative models used calendar time as the time axis., Results: We report 1,136 cases of incident dementia among 4,166 individuals with nonmissing APOE status. Mean [mean ± standard deviation (SD)] 10-y average PM 2.5 was 10.1   ( ± 2.9 )   μ g / m 3 . Each 1 - μ g / m 3 increase in the moving average of 10-y PM 2.5 was associated with a 16% greater hazard of all-cause dementia [1.16 (95% confidence interval: 1.03, 1.31)]. Results using calendar time as the time axis were similar., Discussion: In this prospective cohort study with extensive exposure data and consensus-based outcome ascertainment, elevated long-term exposure to PM 2.5 was associated with increased hazard of all-cause dementia. We found that optimal control of age and time confounding could be achieved through use of either age or calendar time as the time axis in our study. Our results strengthen evidence on the neurodegenerative effects of PM 2.5 . https://doi.org/10.1289/EHP9018.
