Contribution of Individual- and Neighborhood-Level Social, Demographic, and Health Factors to COVID-19 Hospitalization Outcomes.

BACKGROUND: Although disparities in COVID-19 outcomes have been observed, factors contributing to these differences are not well understood. OBJECTIVE: To determine whether COVID-19 hospitalization outcomes are related to neighborhood-level social vulnerability, independent of patient-level clinical factors. DESIGN: Pooled cross-sectional study of prospectively collected data. SETTING: 38 Michigan hospitals. PATIENTS: Adults older than 18 years hospitalized for COVID-19 in a participating site between March and December 2020. MEASUREMENTS: COVID-19 outcomes included acute organ dysfunction, organ failure, invasive mechanical ventilation, intensive care unit stay, death, and discharge disposition. Social vulnerability was measured by the social vulnerability index (SVI), a composite measure of social disadvantage. RESULTS: Compared with patients in low-vulnerability ZIP codes, those living in high-vulnerability ZIP codes were more frequently treated in the intensive care unit (29.0% vs. 24.5%); more frequently received mechanical ventilation (19.3% vs. 14.2%); and experienced higher rates of organ dysfunction (51.9% vs. 48.6%), organ failure (54.7% vs. 51.6%), and in-hospital death (19.4% vs. 16.7%). In mixed-effects regression analyses accounting for age, sex, and comorbid conditions, an increase in a patient's neighborhood SVI by 0.25 (1 quartile) was associated with greater likelihood of mechanical ventilation (increase of 2.1 percentage points), acute organ dysfunction (increase of 2.8 percentage points), and acute organ failure (increase of 2.8 percentage points) but was not associated with intensive care unit stay, mortality, or discharge disposition. LIMITATION: Observational data focused on hospitalizations in a single state. CONCLUSION: Hospitalized patients with COVID-19 from socially vulnerable neighborhoods presented with greater illness severity and required more intensive treatment, but once hospitalized they did not experience differences in hospital mortality or discharge disposition. Policies that target socially vulnerable neighborhoods and access to COVID-19 care may help ameliorate health disparities.

Increased Intraoperative Faculty Entrustment and Resident Entrustability Does Not Compromise Patient Outcomes After General Surgery Procedures.

BACKGROUND: Intraoperative resident autonomy has been compromised secondary to expectations for increased supervision without defined parameters for safe progressive independence, diffusion of training experience, and more to learn with less time. Surgical residents who are insufficiently entrusted during training attain less autonomy, confidence, and even clinical competency, potentially affecting future patient outcomes. OBJECTIVE: To determine if OpTrust, an educational intervention for increasing intraoperative faculty entrustment and resident entrustability, negatively impacts patient outcomes after general surgery procedures. METHODS: Surgical faculty and residents received OpTrust training and instruction to promote intraoperative faculty entrustment and resident entrustability. A post-intervention OpTrust cohort was compared to historical and pre-intervention OpTrust cohorts. Multivariable logistic and negative binomial regression was used to evaluate the impact of the OpTrust intervention and time on patient outcomes. SETTING: Single tertiary academic center. PARTICIPANTS: General surgery faculty and residents. MAIN OUTCOMES AND MEASURES: Thirty-day postoperative outcomes, including mortality, any complication, reoperation, readmission, and length of stay. RESULTS: A total of 8890 surgical procedures were included. After risk adjustment, overall patient outcomes were similar. Multivariable regression estimating the effect of the OpTrust intervention and time revealed similar patient outcomes with no increased risk (P > 0.05) of mortality {odds ratio (OR), 2.23 [95% confidence interval (CI), 0.87-5.6]}, any complication [OR, 0.98 (95% CI, 0.76-1.3)], reoperation [OR, 0.65 (95% CI, 0.42-1.0)], readmission [OR, 0.82 (95% CI, 0.57-1.2)], and length of stay [OR, 0.99 (95% CI, 0.86-1.1)] compared to the historic and pre-intervention OpTrust cohorts. CONCLUSIONS: OpTrust, an educational intervention to increase faculty entrustment and resident entrustability, does not compromise postoperative patient outcomes. Integrating faculty and resident development to further enhance entrustment and entrustability through OpTrust may help facilitate increased resident autonomy within the safety net of surgical training without negatively impacting clinical outcomes.

Fetal Risk Stratification and Outcomes in Children with Prenatally Diagnosed Lung Malformations: Results from a Multi-Institutional Research Collaborative.

OBJECTIVE: The aim of this study was to assess current clinical outcomes in children with prenatally diagnosed congenital lung malformations (CLMs) and to identify prenatal characteristics associated with adverse outcomes. SUMMARY BACKGROUND DATA: Despite a wide spectrum of clinical disease, the identification of fetal CLM subgroups at increased risk for hydrops and respiratory compromise at delivery has not been well defined. METHODS: A retrospective cohort study was conducted using an operative database of prenatally diagnosed CLMs managed at 11 children's hospitals from 2009 to 2016. Statistical analyses were performed using nonparametric bivariate or multivariable logistic regression. RESULTS: Three hundred forty-four children were analyzed. Fifteen (5.5%) fetuses were managed with maternal steroids in the setting of hydrops, and prenatal surgical intervention was uncommon (1.7%). Seventy-five (21.8%) had respiratory symptoms at birth, and 34 (10.0%) required neonatal lung resection. Congenital pulmonary airway malformation volume ratio (CVR) measurements were recorded in 169 (49.1%) cases and were significantly associated with perinatal outcome, including hydrops, respiratory distress at birth, need for supplemental oxygen, neonatal ventilator use, and neonatal resection ( P < 0.001). An initial CVR ≤1.4 was significantly correlated with a reduced risk for hydrops [area under the curve (AUC), 0.93; 95% confidence interval (CI), 0.87-1.00]. A maximum CVR <0.9 (AUC, 0.72; 95% CI, 0.67-0.85) was associated with a low risk for respiratory symptoms at birth. CONCLUSIONS: In this large, multi-institutional study, an initial CVR ≤ 1.4 identifies fetuses at very low risk for hydrops, and a maximum CVR < 0.9 is associated with asymptomatic disease at birth. These findings represent an opportunity for standardization and quality improvement for prenatal counseling and delivery planning.

Associations of 4 Geographic Social Vulnerability Indices With US COVID-19 Incidence and Mortality.

Objectives. To examine and compare how 4 indices of population-level social disadvantage-the Social Vulnerability Index (SVI), the Area Deprivation Index (ADI), the COVID-19 Community Vulnerability Index (CCVI), and the Minority Health-Social Vulnerability Index (MH-SVI)-are associated with COVID-19 outcomes. Methods. Spatial autoregressive models adjusted for population density, urbanicity, and state fixed effects were used to estimate associations of county-level SVI, MH-SVI, CCVI, and ADI values with COVID-19 incidence and mortality. Results. All 4 disadvantage indices had similar positive associations with COVID-19 incidence. Each index was also significantly associated with COVID-19 mortality, but the ADI had a stronger association than the CCVI, MH-SVI, and SVI. Conclusions. Despite differences in component measures and weighting, all 4 of the indices we assessed demonstrated associations between greater disadvantage and COVID-19 incidence and mortality. Public Health Implications. Our findings suggest that each of the 4 disadvantage indices can be used to assist public health leaders in targeting ongoing first-dose and booster or third-dose vaccines as well as new vaccines or other resources to regions most vulnerable to negative COVID-19 outcomes, weighing potential tradeoffs in their political and practical acceptability.

Longitudinal trends in enrollees' employment and student status after Medicaid expansion.

BACKGROUND: Medicaid community engagement requirements previously received federal approval in 12 states, despite limited data on their impact on enrollees' employment-related activities. Our objective was to assess longitudinal changes in enrollees' employment and student status after implementation of Michigan's Medicaid expansion. METHODS: Longitudinal telephone survey of Michigan Medicaid expansion enrollees in 2016 (response rate [RR] = 53.7%), 2017 (RR = 83.4%), and 2018 (N = 2,608, RR = 89.4%) serially assessing self-reported employment or student status. Survey responses were benchmarked against statewide changes in assessed similar low-income adults in the U.S. Census Bureau Current Population Survey. We used mixed models with individual random effects to assess changes in the proportion of enrollees who were employed or students by year. RESULTS: Most respondents had incomes < 100% FPL (61.7% with 0-35% of the federal poverty level [FPL], 22.9% with 36-99% FPL, and 15.4% with 100-133% FPL), 89.3% had at least a high school diploma/equivalent, and they ranged in age (39.6% age 19-34, 34.5% age 35-50, 25.9% age 51-64). Employment or student status increased significantly among Michigan Medicaid expansion respondents, from 54.5% in 2016 to 61.4% in 2018 (P < 0.001), including among those with a chronic condition (47.8% to 53.8%, P < 0.001) or mental health/substance use disorder (48.5% to 56.0%, P < 0.001). In contrast, the statewide proportion of low-income non-elderly adults who were employed or students did not change significantly (from 42.7% in 2016 to 46.0% in 2018, P = 0.57). CONCLUSIONS: Medicaid expansion, absent a community engagement requirement, was associated with increased employment and related activities. The role of Medicaid in providing safety-net coverage to individuals during times of economic stress is likely to grow.

The Impact of the Affordable Care Act Medicaid Expansion on Racial/Ethnic and Sex Disparities in HIV Testing: National Findings from the Behavioral Risk Factor Surveillance System.

INTRODUCTION: Over half of Americans have not been tested for HIV in their lifetime, and over a third of all HIV diagnoses are made less than a year before progression to AIDS. The Affordable Care Act (ACA) Medicaid expansion of 2014 had potential to improve HIV and other health screenings. We assessed the differential impacts of Medicaid expansion on racial/ethnic and racial/ethnic-sex disparities in HIV testing. METHODS: Using Behavioral Risk Factor Surveillance System data from all 50 states and D.C., we sampled low-income (≤ 138% of the federal poverty level) adults ages 19-64 who were non-pregnant and non-disabled. Using a difference-in-differences (DD) and triple difference-in-differences (DDD) study design, we assessed differential impacts by race/ethnicity (White, Black, Hispanic, and other) and race/ethnicity-sex between 2011 and 2013 and 2014-2018. Outcomes were (1) ever having received an HIV test and (2) having received an HIV test in the last year. RESULTS: Overall, Medicaid expansion was associated with a significant increase in HIV testing (p = 0.003). White females and Black males appeared most likely to benefit from this increase (DD 4.5 and 4.8 percentage points; p = 0.001 and 0.130 respectively). However, despite having baseline higher rates of HIV diagnosis, Black and Hispanic females did not have increased rates of ever having HIV testing following Medicaid expansion (DD - 1.9 and 0.9 percentage points; p = 0.391 and 0.703, respectively), including when compared to a White male reference subgroup and across other race/ethnicity-sex subgroups. CONCLUSIONS: Medicaid expansion was associated with an increased overall probability of HIV testing among low-income, nonelderly adults, but certain groups including Black females were not more likely to benefit from this increase, despite being disproportionately affected by HIV at baseline. Targeted and culturally informed interventions to increase Medicaid enrollment and access to primary care may be needed to expand HIV testing in vulnerable groups.

Serum citrullinated histone H3 concentrations differentiate patients with septic verses non-septic shock and correlate with disease severity.

PURPOSE: Microbial infection stimulates neutrophil/macrophage/monocyte extracellular trap formation, which leads to the release of citrullinated histone H3 (CitH3) catalyzed by peptidylarginine deiminase (PAD) 2 and 4. Understanding these molecular mechanisms in the pathogenesis of septic shock will be an important next step for developing novel diagnostic and treatment modalities. We sought to determine the expression of CitH3 in patients with septic shock, and to correlate CitH3 levels with PAD2/PAD4 and clinically relevant outcomes. METHODS: Levels of CitH3 were measured in serum samples of 160 critically ill patients with septic and non-septic shock, and healthy volunteers. Analyses of clinical and laboratory characteristics of patients were conducted. RESULTS: Levels of circulating CitH3 at enrollment were significantly increased in septic shock patients (n = 102) compared to patients hospitalized with non-infectious shock (NIC) (n = 32, p < 0.0001). The area under the curve (95% CI) for distinguishing septic shock from NIC using CitH3 was 0.76 (0.65-0.86). CitH3 was positively correlated with PAD2 and PAD4 concentrations and Sequential Organ Failure Assessment Scores [total score (r = 0.36, p < 0.0001)]. The serum levels of CitH3 at 24 h (p < 0.01) and 48 h (p < 0.05) were significantly higher in the septic patients that did not survive. CONCLUSION: CitH3 is increased in patients with septic shock. Its serum concentrations correlate with disease severity and prognosis, which may yield vital insights into the pathophysiology of sepsis.

Surgical management of pediatric renin-mediated hypertension secondary to renal artery occlusive disease and abdominal aortic coarctation.

BACKGROUND: Renovascular hypertension (RVH) associated with renal artery and abdominal aortic narrowings is the third most common cause of pediatric hypertension. Untreated children may experience major cardiopulmonary complications, stroke, renal failure, and death. The impetus of this study was to describe the increasingly complex surgical practice for such patients with an emphasis on anatomic phenotype and contemporary outcomes after surgical management as a means of identifying those factors responsible for persistent or recurrent hypertension necessitating reoperation. METHODS: A retrospective analysis was performed of consecutive pediatric patients with RVH undergoing open surgical procedures at the University of Michigan from 1991 to 2017. Anatomic phenotype and patient risk factors were analyzed to predict outcomes of blood pressure control and the need for secondary operations using ordered and binomial logistic multinomial regression models, respectively. RESULTS: There were 169 children (76 girls, 93 boys) who underwent primary index operations at a median age of 8.3 years; 31 children (18%) had neurofibromatosis type 1, 76 (45%) had abdominal aortic coarctations, and 28 (17%) had a single functioning kidney. Before treatment at the University of Michigan, 51 children experienced failed previous open operations (15) or endovascular interventions (36) for RVH at other institutions. Primary surgical interventions (342) included main renal artery (136) and segmental renal artery (10) aortic reimplantation, renal artery bypass (55), segmental renal artery embolization (10), renal artery patch angioplasty (8), resection with reanastomosis (4), and partial or total nephrectomy (25). Non-renal artery procedures included patch aortoplasty (32), aortoaortic bypass (32), and splanchnic arterial revascularization (30). Nine patients required reoperation in the early postoperative period. During a mean follow-up of 49 months, secondary interventions were required in 35 children (21%), including both open surgical (37) and endovascular (14) interventions. Remedial intervention to preserve primary renal artery patency or a nephrectomy if such was impossible was required in 22 children (13%). The remaining secondary procedures were performed to treat previously untreated disease that became clinically evident during follow-up. Age at operation and abdominal aortic coarctation were independent predictors for reoperation. The overall experience revealed hypertension to be cured in 74 children (44%), improved in 78 (46%), and unchanged in 17 (10%). Children undergoing remedial operations were less likely (33%) to be cured of hypertension. There was no perioperative death or renal insufficiency requiring dialysis after either primary or secondary interventions. CONCLUSIONS: Contemporary surgical treatment of pediatric RVH provides a sustainable overall benefit to 90% of children. Interventions in the very young (<3 years) and concurrent abdominal aortic coarctation increase the likelihood of reoperation. Patients undergoing remedial surgery after earlier operative failures are less likely to be cured of hypertension. Judicious postoperative surveillance is imperative in children surgically treated for RVH.

Calculating Observed-to-Expected Total Fetal Lung Volume in CDH Fetuses in Twin Gestation: Is There a Better Way?

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a potentially lethal birth defect, and identifying prenatal predictors of outcome is important. Observed-to-expected total fetal lung volume (o/e TFLV) has been shown to be a predictor of severity and useful in risk stratification but is variable due to different TFLV formulas. OBJECTIVES: To calculate o/e TFLV for CDH patients part of a twin gestation using the unaffected sibling as an internal control and comparing these values to those calculated using published formulas for TFLV. METHODS: Seven twin gestations with one fetus affected by CDH were identified between 2006 and 2017. The lung volume for each twin was calculated using magnetic resonance imaging (MRI), and o/e TFLV was calculated using the unaffected twin's TFLV. This percentage was then compared to the o/e TFLV calculated using published formulas. RESULTS: Lung volumes in the unaffected twins were within normal ranges at the lower end of the spectrum. No single TFLV formula was found to correlate perfectly. Intraclass correlation coefficient estimate was most consistent for o/e TFLV calculated with the Meyers formula and supported by Bland-Altman plots. CONCLUSIONS: O/e TFLV measured in CDH/non-CDH twin gestations using the unaffected sibling demonstrated agreement with o/e TFLV calculated using the Meyers formula. We urge the fetal community to standardize the method, use, and interpretation of fetal MRI in the prenatal evaluation of CDH.

Do Personality Traits Mediate the Relationship Between Childhood Abuse and Migraine? An Exploration of the Relationships in Young Adults Using the Add Health Dataset.

BACKGROUND: Personality traits (especially neuroticism) and childhood maltreatment have been independently related to many negative health outcomes later in life, including migraine. Studies have also shown the association between childhood maltreatment and maladaptive personality traits. The mediating role of personality traits on the relationship between childhood maltreatment and depression, psychological distress, and alcohol dependence has been extensively studied. However, this type of mediation has not been studied in the case of the development of migraine. This study investigated (1) the main effects of childhood abuse on personality traits, and of personality traits on migraine, and (2) the mediating role of neuroticism, on the relationship between childhood abuse and migraine in young adults. METHOD: We analyzed retrospective, cross-sectional data from 13,493 adults aged 24-32 years in Wave 4 of the National Longitudinal Survey of Adolescent Health ("Add Health") data set. Participants were queried regarding maltreatment (emotional, physical, and sexual) during childhood, current Big Five personality traits (using mini International Personality Item Pool), current depression (using Center for Epidemiologic Studies-Depression Scale), perceived stress (Using Cohen's Perceived Stress Scale), and diagnosis of migraine by a health care provider. Linear and logistic regressions were used to assess the main effects of childhood maltreatment on the five personality traits (openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism) and the main effect of the personality traits on self-reported provider diagnosis of migraine. A structural equation model (SEM) was used to examine the mediating role of neuroticism on the relationship between childhood maltreatment and migraine. RESULTS: Linear regression models showed that childhood abuse independently predicted increased neuroticism (ß = 0.338, SE=±0.05, P < .001), and increased openness to experiences (ß = 0.341, SE = ±0.06, P < .001) after adjusting for socio-demographic characteristics, current depression, and perceived stress. Logistic regression to examine the main effect of personality traits on migraine revealed that only neuroticism had a significant effect (OR = 1.07, 95%CI = 1.04-1.10) after controlling for childhood abuse, socio-demographic characteristics, current depression, and perceived stress. Our regression analyses showed that neuroticism, but not openness to experience, was a potential mediator for the relationship between childhood abuse and migraine. SEM confirmed significant mediation of the relationship between childhood abuse and migraine through neurotic personality traits (goodness of fit indices: CFI = 0.992, TLI = 0.979, RMSEA = 0.025), unadjusted for socio-demographic variables, depression, and stress. In addition to the indirect effect (ß = 0.039, P < .01) of childhood abuse on migraine through neuroticism, there was also a significant direct effect (ß = 0.143, P < .01) of childhood abuse on migraine. After adjusting for socio-demographic variables, other personality types, depression, and stress, both the direct effect (ß = 0.127; P < .01) of childhood abuse on migraine and the indirect effect (ß = 0.09; P < .01) of childhood abuse on migraine through neuroticism were attenuated, but remained significant. CONCLUSION: Childhood abuse is associated with personality and migraine. An estimated 21% of the total effect of childhood abuse on migraine could be explained by mediation through neuroticism in the unadjusted model. In the fully adjusted model, an estimated 8.7% of the total effect could be explained by mediation, although, self-reported data limit the ability to draw firm conclusions.

A Social Marketing Intervention to Prevent Drowning Among Inner-City Youth.

BACKGROUND: Water-related injuries and fatalities pose serious public health issues, especially to African American youth, a demographic group that drowns at disproportionately high rates. AIM: The purpose of this study was to determine if a social marketing intervention targeting the parents and guardians of inner-city youth (U.S. Midwest) could positively influence their perceptions concerning water safety. METHOD: Researchers employed a quasi-experimental design using matched pairs to evaluate the intervention. Participants consisted of parents who enrolled their children in a six-session survival-swimming course. Guided by the Health Belief Model, the researchers disseminated six prevention messages using six different channels (brochure, e-mail, SMS text message, postcard, Facebook, and window cling). RESULTS: The findings from a two-way analysis of covariance revealed that treatment group participants' knowledge and perceptions of water-related threat all changed favorably. Additionally, all participants planned to reenroll their children in swim lessons. DISCUSSION: A social marketing campaign using the Health Belief Model improved inner-city parents' knowledge regarding water safety and enhanced their self-efficacy. CONCLUSION: This study provides practitioners with feasible strategies (prevention messages) to supplement swim lessons, with the ultimate goal of preventing drowning among at-risk youth.

Emotional Abuse History and Migraine Among Young Adults: A Retrospective Cross-Sectional Analysis of the Add Health Dataset.

OBJECTIVES: To define and examine the relationship between self-reported childhood abuse and migraine among young adults. BACKGROUND: Headache and migraine have been linked to childhood abuse in numerous studies, but there is incomplete characterization of headache types, and limited assessment of abuse types and frequency. Only one population-based study has examined the relationship between emotional abuse and migraine. None have investigated the temporal relationship between onset of abuse and of migraine. METHODS: We analyzed data from 14,356 adults aged 24-32 years in Wave 4, which is a cross-sectional subset of the longitudinal Add Health study. Participants were queried regarding abuse (emotional, physical and sexual) during childhood, diagnosis of migraine, depression and anxiety by healthcare providers, and symptoms of current depression. We used logistic regression to estimate the association between childhood abuse and migraine, controlling for socio-demographic factors, current depression, and lifetime diagnosis of anxiety and depression. RESULTS: About 14% (n = 2040) of respondents reported migraine. Participants with migraine (vs no migraine) reported significantly higher rates of childhood abuse overall (60.6% vs 48.9%), including emotional (57.8% vs 45.4%), sexual (8.4% vs 4.6%) and physical (22.4% vs 17.9%) abuse. Emotional abuse had a stronger association with migraine (odds ratio [OR] 1.62; 95% confidence interval [CI] 1.43-1.85) when compared with physical (OR 1.06; 95% CI 0.89-1.68) and sexual abuse (OR 1.06; 95% CI 0.93-1.68), adjusting for socio-demographic factors. The emotional abuse-migraine association remained even when controlling for lifetime diagnosis of depression and anxiety (OR 1.37; 95% CI 1.19-1.57) and for current depression (OR 1.47; 95% CI 1.30-1.67). The odds of migraine increased with increasing number of abuse types reported. There was a U-shaped distribution of odds of migraine associated with frequency of occurrences of emotional abuse, peaking at one time (OR 1.65; 95% CI 1.34-2.03) and ≥ six times (OR 1.77; 95% CI 1.49-2.10). CONCLUSIONS: Emotional abuse during childhood contributed more than physical or sexual abuse to the development of migraine. There is a dose-response relationship with increasing number of abuse types associated with rising odds of migraine. In addition, the relationship between the frequency of emotional abuse and the odds of migraine follows a U-shape pattern.

Trends in Hospitalizations for Ambulatory Care-Sensitive Conditions During the COVID-19 Pandemic.

Importance: The association of the COVID-19 pandemic with the quality of ambulatory care is unknown. Hospitalizations for ambulatory care-sensitive conditions (ACSCs) are a well-studied measure of the quality of ambulatory care; however, they may also be associated with other patient-level and system-level factors. Objective: To describe trends in hospital admissions for ACSCs in the prepandemic period (March 2019 to February 2020) compared with the pandemic period (March 2020 to February 2021). Design, Setting, and Participants: This cross-sectional study of adults enrolled in a commercial health maintenance organization in Michigan included 1 240 409 unique adults (13 011 176 person-months) in the prepandemic period and 1 206 361 unique adults (12 759 675 person-months) in the pandemic period. Exposure: COVID-19 pandemic (March 2020 to February 2021). Main Outcomes and Measures: Adjusted relative risk (aRR) of ACSC hospitalizations and intensive care unit stays for ACSC hospitalizations and adjusted incidence rate ratio of the length of stay of ACSC hospitalizations in the prepandemic (March 2019 to February 2020) vs pandemic (March 2020 to February 2021) periods, adjusted for patient age, sex, calendar month of admission, and county of residence. Results: The study population included 1 240 409 unique adults (13 011 176 person-months) in the prepandemic period and 1 206 361 unique adults (12 759 675 person-months) in the pandemic period, in which 51.3% of person-months (n = 6 547 231) were for female patients, with a relatively even age distribution between the ages of 24 and 64 years. The relative risk of having any ACSC hospitalization in the pandemic period compared with the prepandemic period was 0.72 (95% CI, 0.69-0.76; P < .001). This decrease in risk was slightly larger in magnitude than the overall reduction in non-ACSC, non-COVID-19 hospitalization rates (aRR, 0.82; 95% CI, 0.81-0.83; P < .001). Large reductions were found in the relative risk of respiratory-related ACSC hospitalizations (aRR, 0.54; 95% CI, 0.50-0.58; P < .001), with non-statistically significant reductions in diabetes-related ACSCs (aRR, 0.91; 95% CI, 0.83-1.00; P = .05) and a statistically significant reduction in all other ACSC hospitalizations (aRR, 0.79; 95% CI, 0.74-0.85; P < .001). Among ACSC hospitalizations, no change was found in the percentage that included an intensive care unit stay (aRR, 0.99; 95% CI, 0.94-1.04; P = .64), and no change was found in the length of stay (adjusted incidence rate ratio, 1.02; 95% CI, 0.98-1.06; P = .33). Conclusions and Relevance: In this cross-sectional study of adults enrolled in a large commercial health maintenance organization plan, the COVID-19 pandemic was associated with reductions in both non-ACSC and ACSC hospitalizations, with particularly large reductions seen in respiratory-related ACSCs. These reductions were likely due to many patient-level and health system-level factors associated with hospitalization rates. Further research into the causes and long-term outcomes associated with these reductions in ACSC admissions is needed to understand how the pandemic has affected the delivery of ambulatory and hospital care in the US.

Image-based prenatal predictors correlate with postnatal survival, extracorporeal life support use, and defect size in left congenital diaphragmatic hernia.

OBJECTIVE: To evaluate the association between prenatal imaging predictors of patients with left-sided congenital diaphragmatic hernia (LCDH) and postnatal outcomes. STUDY DESIGN: CDH study group data were reviewed for LCDH infants born 2015-2019. Prenatal ultrasound (US) and magnetic resonance imaging (MRI) data were collected and correlated with postnatal information including CDHSG defect size (A through D or non-repair (NR)). RESULTS: In total, 929 LCDH patients were included. Both US and MRI imaging predictors correlated with postnatal survival (72.2%) and ECLS use (29.6%). Logistic regression models confirmed increased survival and decreased ECLS use with larger values for all predictors. Importantly, all prenatal values evaluated showed no significant difference between defect size D and NR patients. CONCLUSIONS: This is the largest cohort of LCDH patients and demonstrates that prenatal imaging factors correlate with postnatal outcomes and confirms that patients in the non-repair group are prenatally similar to type D defects.

Transhiatal robot-assisted minimally invasive esophagectomy: unclear benefits compared to traditional transhiatal esophagectomy.

Esophagectomy is a high-risk operation, regardless of technique. Minimally invasive transthoracic esophagectomy could reduce length of stay and pulmonary complications compared to traditional open approaches, but the benefits of minimally invasive transhiatal esophagectomy are unclear. We performed a retrospective review of prospectively gathered data for open transhiatal esophagectomies (THEs) and transhiatal robot-assisted minimally invasive esophagectomies (TH-RAMIEs) performed at a high-volume academic center between 2013 and 2017. Multivariate logistic regression was used to calculate adjusted odds ratios (aORs) for outcomes. 465 patients met inclusion criteria (378 THE and 87 TH-RAMIE). THE patients more likely had an ASA score of 3 + (89.1% vs 77.0%, p = 0.012), whereas TH-RAMIE patients more likely had a pathologic staging of 3+ (43.7% vs. 31.2%, p = 0.026). TH-RAMIE patients were less likely to receive epidurals (aOR 0.06, 95% confidence interval [CI] 0.03-0.14, p < 0.001), but epidural use itself was not associated with differences in outcomes. TH-RAMIE patients experienced higher rates of pulmonary complications (adjusted odds ratio [OR] 1.82, 95% CI 1.03-3.22, p = 0.040), particularly pulmonary embolus (aOR 5.20, 95% CI 1.30-20.82, p = 0.020). There were no statistically significant differences in lymph node harvest, unexpected ICU admission, length of stay, in-hospital mortality, or 30-day readmission or mortality rates. The TH-RAMIE approach had higher rates of pulmonary complications. There were no statistically significant advantages to the TH-RAMIE approach. Further investigation is needed to understand the benefits of a minimally invasive approach to the open transhiatal esophagectomy.

Fibromuscular Dysplasia and Abdominal Aortic Aneurysms Are Dimorphic Sex-Specific Diseases With Shared Complex Genetic Architecture.

BACKGROUND: The risk of arterial diseases may be elevated among family members of individuals having multifocal fibromuscular dysplasia (FMD). We sought to investigate the risk of arterial diseases in families of individuals with FMD. METHODS: Family histories for 73 probands with FMD were obtained, which included an analysis of 463 total first-degree relatives focusing on FMD and related arterial disorders. A polygenic risk score for FMD (PRSFMD) was constructed from prior genome-wide association findings of 584 FMD cases and 7139 controls and evaluated for association with an abdominal aortic aneurysm (AAA) in a cohort of 9693 AAA cases and 294 049 controls. A previously published PRSAAA was also assessed among the FMD cases and controls. RESULTS: Of all first degree relatives of probands, 9.3% were diagnosed with FMD, aneurysms, and dissections. Aneurysmal disease occurred in 60.5% of affected relatives and 5.6% of all relatives. Among 227 female first-degree relatives of probands, 4.8% (11) had FMD, representing a relative risk (RR)FMD of 1.5 ([95% CI, 0.75-2.8]; P=0.19) compared with the estimated population prevalence of 3.3%, though not of statistical significance. Of all fathers of FMD probands, 11% had AAAs resulting in a RRAAA of 2.3 ([95% CI, 1.12-4.6]; P=0.014) compared with population estimates. The PRSFMD was found to be associated with an AAA (odds ratio, 1.03 [95% CI, 1.01-1.05]; P=2.6×10-3), and the PRSAAA was found to be associated with FMD (odds ratio, 1.53 [95% CI, 1.2-1.9]; P=9.0×10-5) as well. CONCLUSIONS: FMD and AAAs seem to be sex-dimorphic manifestations of a heritable arterial disease with a partially shared complex genetic architecture. Excess risk of having an AAA according to a family history of FMD may justify screening in family members of individuals having FMD.

Association of Social and Demographic Factors With COVID-19 Incidence and Death Rates in the US.

Importance: Descriptive data have revealed significant racial/ethnic disparities in coronavirus disease 2019 (COVID-19) cases in the US, but underlying mechanisms of disparities remain unknown. Objective: To examine the association between county-level sociodemographic risk factors and US COVID-19 incidence and mortality. Design, Setting, and Participants: This cross-sectional study analyzed the association between US county-level sociodemographic risk factors and COVID-19 incidence using mixed-effects negative binomial regression, and COVID-19 mortality using zero-inflated negative binomial regression. Data on COVID-19 incidence and mortality were collected from January 20 to July 29, 2020. The association of social risk factors with weekly cumulative incidence and mortality was also examined by interacting time with the index measures, using a random intercept to account for repeated measures. Main Outcomes and Measures: Sociodemographic data from publicly available data sets, including the US Centers for Disease Control and Prevention's Social Vulnerability Index (SVI), which includes subindices of socioeconomic status, household composition and disability, racial/ethnic minority and English language proficiency status, and housing and transportation. Results: As of July 29, 2020, there were a total of 4 289 283 COVID-19 cases and 147 074 COVID-19 deaths in the US. An increase of 0.1 point in SVI score was associated with a 14.3% increase in incidence rate (incidence rate ratio [IRR], 1.14; 95% CI, 1.13-1.16; P < .001) and 13.7% increase in mortality rate (IRR, 1.14; 95% CI, 1.12-1.16; P < .001), or an excess of 87 COVID-19 cases and 3 COVID-19 deaths per 100 000 population for a SVI score change from 0.5 to 0.6 in a midsize metropolitan county; subindices were also associated with both outcomes. A 0.1-point increase in the overall SVI was associated with a 0.9% increase in weekly cumulative increase in incidence rate (IRR, 1.01; 95% CI, 1.01-1.01; P < .001) and 0.5% increase in mortality rate (IRR, 1.01; 95% CI, 1.01-1.01; P < .001). Conclusions and Relevance: In this cross-sectional study, a wide range of sociodemographic risk factors, including socioeconomic status, racial/ethnic minority status, household composition, and environmental factors, were significantly associated with COVID-19 incidence and mortality. To address inequities in the burden of the COVID-19 pandemic, these social vulnerabilities and their root causes must be addressed.

Bolus versus continuous feeding regimens post gastrostomy tube placement in children.

BACKGROUND/PURPOSE: Owing to the frequency of gastrostomy tube placement in children and the numerous regimens used to start feeds after placement we attempted to see if it matters if the initial feeds after a gastrostomy tube placement are provided in a bolus or continuous manner. METHODS: Using a prospective randomized trial, children were randomized to initial bolus or continuous chimney feeding after gastrostomy tube placement. Feeding tolerance and complications related to the gastrostomy tube were collected for 4 weeks after placement. RESULTS: Demographics were similar in the two groups. Times to goal feeds were similar in both groups, but in the first two weeks more feeding modifications were required in the bolus group. Other than the rate of leakage during the second week after placement which occurred more in the bolus group, all other clinical outcomes were similar in the two groups. CONCLUSIONS: Other than minor, clinically insignificant differences noted above, the method of initial feeding after a gastrostomy tube placement does not affect feeding tolerance or gastrostomy tube complication in the first month after placement. LEVEL OF EVIDENCE: Therapeutic, level II.
