Economic Burden of Medically Attended Respiratory Syncytial Virus Infections Among Privately Insured Children Under 5 Years of Age in the USA.

BACKGROUND: The cost of medically attended RSV LRI (lower respiratory infection) is critical in determining the economic value of new RSV immunoprophylaxes. However, most studies have focused on intermittent RSV encounters, not the episode of care that captures the entirety of RSV illness. METHODS: We created age- and condition-specific cohorts of children under 5 years of age using MarketScan® data (2015-2019). We contrasted aggregating healthcare costs over RSV-LRTI episodes to ascertaining costs based on RSV-specific encounters only. Economic burden was estimated by multiplying costs per encounter or per episode by their respective incidence rates. RESULTS: Average cost was higher per episode than per encounter regardless of settings (inpatient: $28,586 vs. $18,056 and outpatient/ED: $2099 vs. $407 for infants). Across ages, the economic burden was highest for infants and RSV-LRTI requiring inpatient care, but the burden in outpatient/ED settings was disproportionately higher than costs due to higher incidence rates (for inpatient vs. outpatient episodes: $226,403 vs. $101,269; for inpatient vs. outpatient encounters: $151,878 vs. $38,819 per 1000 infant-years). For high-risk children, cost and burden were up to 3-10 times higher, respectively. CONCLUSIONS: With a comprehensive stratification by settings and risk condition, the encounter- versus episode-based estimates provide a robust range for policymakers' economic appraisal of new RSV immunoprophylaxes.

Reevaluating the "deaths of despair" narrative: Racial/ethnic heterogeneity in the trend of psychological distress-related death.

Despite the significant scientific advancement in deciphering the "deaths of despair" narrative, most relevant studies have focused on drug-, alcohol-, and suicide-related (DAS) deaths. This study directly investigated despair as a determinant of death and the temporal variation and racial heterogeneity among individuals. We used psychological distress (PD) as a proxy for despair and drew data from the US National Health Interview Survey-Linked Mortality Files 1997 to 2014, CDC (Centers for Disease Control and Prevention) Multiple Cause of Death database 1997 to 2014, CDC bridged-race population files 1997 to 2014, Current Population Survey 1997 to 1999, and the American Community Survey 2000 to 2014. We used Cox proportional hazards models to estimate mortality hazard ratios of PD and compared age-standardized PD- and DAS-related mortality rates by race/ethnicity and over time. We found that while Whites had a lower prevalence of PD than Blacks and Hispanics throughout the whole period, they underwent distinctive increases in PD-related death and have had a higher PD-related mortality rate than Blacks and Hispanics since the early 2000s. This was predominantly due to Whites' relatively high and increasing vulnerability to PD less the prevalence of PD. Furthermore, PD induced a more pervasive mortality consequence than DAS combined for Whites and Blacks. In addition, PD- and DAS-related deaths displayed a concordant trend among Whites but divergent patterns for Blacks and Hispanics. These findings suggest that 1) DAS-related deaths underestimated the mortality consequence of despair for Whites and Blacks but overestimated it for Hispanics; and 2) despair partially contributed to the DAS trend among Whites but probably not for Blacks and Hispanics.

The Usefulness of High-Magnification Loupe for Reducing Biliary Complications After Liver Transplantation.

BACKGROUND: Despite advances in surgical techniques, biliary complications are still considered to be a technical "Achilles' heel" of liver transplantation (LT). The purpose of this study was to evaluate the effect of loupe magnification in reducing biliary complications after LT. MATERIALS AND METHODS: From April 2017 to February 2022, LT was performed on 307 patients in our center. Among them, except for 3 patients who underwent hepaticojejunostomy, 304 adult patients with LT were enrolled. They were divided into 3 groups according to the loupe magnification: 2.5 times (×2.5 group, n = 105), 3.5 times (×3.5 group, n = 95), and 5.0 times (×5.0 group, n = 105). RESULTS: Biliary complications occurred in 63 (20.7%) patients. Anastomosis site leakage occurred in 37 patients (12.2%), and stricture occurred in 52 patients (17.1%). Anastomosis site leakage occurred in 15 patients (14.3%) in the ×2.5 group, 15 patients (16.0%) in the ×3.5 group, and 7 patients (6.7%) in the ×5.0 group (P = .097). Biliary stricture occurred in 26 patients (24.8%) in the ×2.5 group, 15 patients (16.0%) in the ×3.5 group, and 11 patients (10.5%) in the ×5.0 group (P = .021). Total biliary complications occurred in 31 patients (29.5%) in the ×2.5 group, 19 patients in the ×3.5 group (20.2%), and 13 patients in the ×5.0 group (12.4%) (P = .009). CONCLUSION: The use of a high magnification loupe can reduce biliary complications in liver transplantation. Further large-scale analyses of clinical data or randomized controlled trials are required to support this study.

Effects of Livact Granule on Liver Function Recovery After Donor Right Hemi-Hepatectomy.

BACKGROUND: Living donor liver transplantation (LDLT) is currently widespread due to organ shortage. Because LDLT is a high-risk surgery for the donor, donor safety becomes an important issue. In adult LDLT, right lobe grafts are usually used, posing a greater risk to the donor than a left lobe. Reports have demonstrated that branched-chain amino acids help patients recover after hepatectomy. This study aimed to evaluate the effect of Livact granule on donor safety and recovery. METHODS: From January 2016 to December 2021, LDLT was performed on 258 patients at our center. Among them, 148 were in the non-Livact group, and 110 were in the Livact group. Six of 110 patients in the Livact group stopped taking the granules due to nausea and vomiting, leaving 104 patients in the Livact group to be analyzed. Various preoperative and postoperative factors were evaluated to assess donor safety and recovery. RESULTS: In the non-Livact group, the mean donor age was 35.8; in the Livact group, it was 40. There were no differences between the 2 groups in preoperative liver function tests and no difference in future liver remnant or steatosis. There was no difference in total bilirubin level between the 2 groups at 5 days postoperatively; however, in the Livact group, the prothrombin time international normalized ratio was lower, and albumin was higher. The days taken for total bilirubin to normalize were the same in both groups, but fewer days were needed for Livact to realize an international normalized ratio. More patients in the non-Livact group were discharged with the Jackson-Pratt drain because the drainage did not decrease. CONCLUSIONS: In donor right hepatectomy patients, taking Livact granules and branched-chain amino acids helps donor recovery. For donor safety, administration of Livact granules during the perioperative period should be considered.

Proposal of a Network System to Solve the Problem of Small Volume in Liver Transplantation; Catholic Medical Center Network.

INTRODUCTION: Liver transplantation (LT) is a complex and demanding procedure associated with significant perioperative challenges and risks. Concerns have arisen regarding LT outcomes in low-volume centers. We implemented an integrated training and surgical team network to address these concerns within the Catholic Medical Center (CMC) network. This study presents a comprehensive review of our 9-year LT experience within the CMC medical network. METHOD: A retrospective study of LT procedures conducted between January 2013 and August 2021 in 6 CMC-affiliated hospitals was performed. One center was categorized as a high-volume center, conducting over 60 cases annually, and the remaining 5 were considered small-volume centers. The primary endpoints assessed were 1-year and 5-year survival rates. RESULTS: A total of 793 LTs were performed during the study period. The high-volume center performed 411 living donor LT (LDLT) cases and 127 deceased donor LT (DDLT) cases. Also, 146 LDLT cases and 109 DDLT cases were performed in 5 small-volume centers. One-year and 5-year patient survival for LDLT recipients was 88.3% and 78.8% in the high-volume center and 85.6% and 80.6% in the low-volume center. Five-year survival was not significantly different in small-volume centers (P = .903). For DDLT recipients, 1-year and 5-year patient survival was 80.3% and 70.6% in the high-volume center and 76.1% and 67.6% in the low-volume center. In DDLT cases, 5-year survival was not significantly different in small-volume centers (P = .445). CONCLUSION: In conclusion, comparable outcomes for liver transplantation can be obtained in a small-volume center with a high level of integrated training systems and networks.

The short-term effect of ambient particulate matter on suicide death.

BACKGROUND: Air pollution can cause various respiratory and neurological diseases and continuous exposure can lead to death. Previous studies have reported that particulate matter (PM) exposure increases the risk of depression, suicidal thoughts, and suicidal death; however, the results are inconsistent and limited. This study aimed to examine the relationship between short-term PM exposure and suicide deaths, as well as investigate the short-term effects of PM on suicide death within vulnerable groups based on factors such as sex, age group, suicide-related information (note, method, and cause), psychiatric disorders, and physical diseases. METHODS: Data on a total of 28,670 suicide deaths from 2013 to 2017, provided by the Korea Foundation for Suicide Prevention, were analyzed. The study design employed a time-series analysis with a two-stage approach. In the first step, a generalized additive model combined with a distributed lag nonlinear model was used to estimate the short-term effect of PM exposure on suicide risk specific to each city. In the second step, the estimated results from each city were pooled through a meta-analysis to derive the overall effect. We determined the effects of single lag, cumulative lag, and moving average PM concentrations from days 0-7 before suicide. RESULTS: We confirmed an association between exposure to PM10 (≤ 10 µm in diameter) and deaths due to suicide. In particular, among individuals with psychiatric disorders and those who employed non-violent suicide methods, increased exposure to PM10 was associated with a higher risk of death by suicide, with percentage changes of 5.92 (95% confidence interval [CI]: 3.95-7.92) and 11.47 (95% CI: 7.95-15.11), respectively. Furthermore, in the group with psychiatric disorders, there was an observed tendency of increasing suicide risk as PM10 levels increased up to 120 µg/m3, whereas in the group with non-violent suicide deaths, there was a pronounced trend of rapid increase in suicide risk with an increase in PM10 up to 100 µg/m3. CONCLUSIONS: These results show an association between short-term exposure to PM and suicide. Our study adds evidence for the benefits of reducing PM in preventing diseases and improving mental health.

Understanding the health decline of Americans in boomers to millennials.

Morbidity and mortality are on the rise among Americans from Boomers to Millennials. We investigate early-life diseases and the socioeconomic, psychosocial, and bio-behavioral factors behind this worsening health trend. Using data from the Panel Study of Income Dynamics Family and Individual Files 1968-2013, we find that the chronic disease index and poor subjective health have continuously increased for Baby Boomers and later cohorts. Early-life diseases, obesity, and shortening job tenure account for about half the health decline across cohorts. Weakening union protection, decreasing marriage, and declining religion only make minor contributions. All other factors, including early life nutrition and family background, adulthood socioeconomic status, physical activity, and smoking behaviors, make negative or non-significant contributions. These findings highlight that even though recent cohorts have better childhood nutrition, family socioeconomic environment,and higher levels of education and income, these advantages have been offset by elevated early-life disease exposure, obesity, and a precarious labor market. We discuss the findings in the context of Case and Deaton's "cumulative deprivation" thesis.

Cost of Medically Attended RSV Among Medicaid Beneficiaries ≤2 Years of Age by Underlying Risk Condition.

We evaluated costs for respiratory syncytial virus (RSV) medical attention in children aged <24 months using MarketScan® Medicaid Multi-State claims database 2015-2019. Average cost was highest for RSV hospitalization with intensive care unit (ICU) admission ($23 514-24 835), followed by no ICU admission ($8039-8990), ED visits ($463-482), and outpatient visits ($145-151). Cost was higher for those with comorbidities.

A practical development protocol for evidence-based digital integrative arts therapy content in public mental health services: digital transformation of mandala art therapy.

Introduction: The fundamentals of digital transformation include the conversion of the traditional method into a digital format to develop a standardized system that collects, analyzes, and processes quantitative data. This study aims to provide a comprehensive understanding of the development process and key elements of evidence-based digital integrative arts therapy. Methods: The "Digital Mandala" service in the "Mental Health App" produced as part of a national public mental health project for personalized depression management is adopted to explain how to convert the existing mandala art therapy into digital format. A living lab approach has been applied, which can be used to address the nation's mental health challenges by promoting collaboration, innovation, and evidence-based solutions. Results: Evidence-based digital content requires evidence that covers the structural process, the effects of existing methods, and the components and meanings of each detailed scene. In this section, we provide five stages of the development process, including preliminary research, design, development, commercialization, and advancement. Consequently, clinical elements, integrative arts therapy features, and data factors are defined as the key principles of evidence-based digital integrative arts therapy. Discussion: Based on the data factors found in this study, it will be possible to create an evaluation dataset of digital integrative arts therapy content for managing depression. Additionally, the large-scale public data can be analyzed through artificial intelligence technology, which is expected to be used as a basis for deriving significant results in a new form, going further than the existing evaluation method. This research is significant because it establishes the foundation for digital transformation in the field of art therapy for public mental health services and investigates its potential.

The clinical effectiveness of fused image of single-photon emission CT and facial CT for the evaluation of degenerative change of mandibular condylar head.

BACKGROUND: The primary objective of this study was to assess the clinical effectiveness of fused images obtained from single-photon emission computed tomography (SPECT) and facial computed tomography (CT) for evaluating degenerative changes in the mandibular condylar head. This assessment was accomplished by comparing the Technetium-99 m methylene diphosphonate (99mTc-MDP) uptake ratio with the results of clinical and radiographic findings. METHODS: The study included 17 patients (3 males and 14 females) with suspected osteoarthritis of the mandibular condyle, totaling 34 temporomandibular joints (TMJs). Based on clinical and radiographic examinations, the TMJs were categorized into four groups: normal (group N), internal derangement (group ID), osteoarthritis (group OA), and osteoarthritis sequelae (group OAseq). For each patient, bone SPECT and facial CT scans were registered and reconstructed to create fused SPECT/CT images. The 99mTc-MDP uptake levels in the TMJs were statistically compared among the four groups. RESULTS: The 99mTc-MDP uptake ratio showed a gradual increase in the order of the following: group N, group OAseq, group ID, and group OA. There was a significant difference observed among groups (p = 0.003), mainly driven by the disparity between group OA and both group N (p < 0.001) and group OAseq (p = 0.048). CONCLUSION: Fused SPECT/CT image can be an effective tool for evaluating degenerative changes in the mandibular condylar head. The technique demonstrated the ability to differentiate between normal TMJs and those with internal derangement, osteoarthritis, or osteoarthritis sequelae. This approach holds promise as a valuable method in clinical assessments of TMJ degeneration.

Healthcare-Associated Respiratory Syncytial Virus in Children's Hospitals.

BACKGROUND: Outbreaks of healthcare-associated respiratory syncytial virus (HA-RSV) infections in children are well described, but less is known about sporadic HA-RSV infections. We assessed the epidemiology and clinical outcomes associated with sporadic HA-RSV infections. METHODS: We retrospectively identified hospitalized children ≤18 years old with HA-RSV infections in six children's hospitals in the United States during the respiratory viral seasons October-April in 2016-2017, 2017-2018, and 2018-2019 and prospectively from October 2020 through November 2021. We evaluated outcomes temporally associated with HA-RSV infections including escalation of respiratory support, transfer to the pediatric intensive care unit (PICU), and in-hospital mortality. We assessed demographic characteristics and comorbid conditions associated with escalation of respiratory support. RESULTS: We identified 122 children (median age 16.0 months [IQR 6, 60 months]) with HA-RSV. The median onset of HA-RSV infections was hospital day 14 (IQR 7, 34 days). Overall, 78 (63.9%) children had two or more comorbid conditions; cardiovascular, gastrointestinal, neurologic/neuromuscular, respiratory, and premature/ neonatal comorbidities were most common. Fifty-five (45.1%) children required escalation of respiratory support and 18 (14.8%) were transferred to the PICU. Five (4.1%) died during hospitalization. In the multivariable analysis, respiratory comorbidities (aOR: 3.36 [CI95 1.41, 8.01]) were associated with increased odds of escalation of respiratory support. CONCLUSIONS: HA-RSV infections cause preventable morbidity and increase healthcare resource utilization. Further study of effective mitigation strategies for HA-respiratory viral infections should be prioritized; this priority is further supported by the impact of the COVID-19 pandemic on seasonal viral infections.

Respiratory syncytial virus reinfections among infants and young children in the United States, 2011-2019.

BACKGROUND: Although respiratory syncytial virus (RSV) immunoprophylaxis is recommended for high-risk infants, the American Academy of Pediatrics (AAP) recommends against immunoprophylaxis in the same season following a breakthrough hospitalization due to limited risk for a second hospitalization. Evidence in support of this recommendation is limited. We estimated population-based re-infection rates from 2011-2019 in children <5 years since RSV risk remains relatively high in this age group. MATERIALS AND METHODS: Using claims data from private insurance enrollees, we established cohorts of children <5 years who were followed to ascertain annual (July 1-June 30) and seasonal (November 1- February 28/29) RSV recurrence estimates. Unique RSV episodes included inpatient encounters with RSV diagnosis ≥30 days apart, and outpatient encounters ≥30 days apart from each other as well as from inpatient encounters. The risk of annual and seasonal re-infection was calculated as the proportion of children with a subsequent RSV episode in the same RSV year/season. RESULTS: Over the 8 assessed seasons/years (N = 6,705,979) and across all age groups annual inpatient and outpatient infection rates were 0.14% and 1.29%, respectively. Among children with a first infection, annual inpatient and outpatient re-infection rates were 0.25% (95% confidence interval (CI) = 0.22-0.28) and 3.44% (95% CI = 3.33-3.56), respectively. Both infection and re-infection rates declined with age. CONCLUSION: While medically-attended re-infections contributed numerically only a fraction of the total RSV infections, re-infections among those with previous infection in the same season were of similar magnitude as the general infection risk, suggesting that a previous infection may not attenuate the risk for a re-infection.

Predictors of cognitive functioning trajectories among older Americans: A new investigation covering 20 years of age- and non-age-related cognitive change.

Despite the extensive study of predictors of cognitive decline in older age, a key uncertainty is how much these predictors explain both the intercept and age- and non-age-related change in cognitive functioning (CF). We examined the contribution of a broad range of life course determinants to CF trajectories. Data came from 7,068 participants in the 1996-2016 Health and Retirement Study. CF was measured as a summary score on a 27-point cognitive battery of items. We estimated multilevel growth curve models to examine the CF trajectories in individuals ages 54-85. We found that the variation in CF level at age 54 was three times as much as the variation in age slope. All the observed individual predictors explained 38% of the variation in CF at age 54. Personal education was the most important predictor (25%), followed by race, household wealth and income, parental education, occupation, and depression. The contributions of activity limitations, chronic diseases, health behaviors (obesity, smoking, vigorous activity), childhood conditions (childhood health, nutrition, financial situation), gender, marital status, and religion were rather small (<5%). Even though the age slope varied with many adulthood factors, they only explained 5.6% of the between-person variation in age slope. Moreover, age explained 23% of within-person variation in CF from age 54 to 85. The rest non-age-related within-person variation could not be explained by the observed time-varying factors. These findings suggest that future research is urgently needed to discover the main determinants of the slope of cognitive decline to slow down the progression of cognitive impairment and dementia.

Immigrant-origin youths at risk: Trends in suicidal behaviors among Korean adolescents by immigrant origins and ethnic options (2011-2019).

BACKGROUND: In line with the immigrant paradox, immigrants' health advantages disappear among second-generation immigrant-origin youths, including a high prevalence of suicidal behaviors. Nevertheless, the secular trend in suicidal behaviors among immigrants in South Korea has not been examined. While Korean society was once considered homogeneous, intra-Asian migration has increased in recent decades. It is needed to explore the relationship between ethnic options and mental health outcomes among immigrant-origin youths, including suicidal behaviors. METHODS: Using the nationally representative Korean Youth Risk Behavior Survey from 2011 to 2019 (600,541 non-immigrant-origin and 6,085 immigrant-origin), we examined the rates of suicidal behaviors to identify trends among youths with/without immigrant-origin and depending on the visibility of their immigrant-origin. Then, we conducted logistic regression to examine whether visibility is associated with higher suicidal behaviors among immigrant-origin youths. RESULTS: Overall, suicidal behaviors have declined, but immigrant-origin youths showed higher levels of suicidal behaviors than non-immigrant-origin youths. Visible minority youths showed higher suicidal behaviors than their invisible counterparts, particularly in suicidal planning and suicide attempts. Among immigrant-origin youths, visible minority status was associated with higher suicidal thoughts, plans, and attempts, controlling for socio-economic factors. Furthermore, female immigrant-origin youths show higher suicidal behaviors than their male counterparts. CONCLUSIONS: The results suggest that data disaggregation is needed when examining the mental health of immigrant-origin youths. Practitioners and policymakers should pay particular attention to immigrant-origin youths and recognize that their visibility may be associated with their risk of suicidal behaviors. Targeted intervention is also required for female visible minority youths.

Clinical impact of healthcare-associated respiratory syncytial virus in hospitalized adults.

OBJECTIVE: To describe the clinical impact of healthcare-associated (HA) respiratory syncytial virus (RSV) in hospitalized adults. DESIGN: Retrospective cohort study within a prospective, population-based, surveillance study of RSV-infected hospitalized adults during 3 respiratory seasons: October 2017-April 2018, October 2018-April 2019, and October 2019-March 2020. SETTING: The study was conducted in 2 academically affiliated medical centers. PATIENTS: Each HA-RSV patient (in whom RSV was detected by PCR test ≥4 days after hospital admission) was matched (age, sex, season) with 2 community-onset (CO) RSV patients (in whom RSV was detected ≤3 days of admission). METHODS: Risk factors and outcomes were compared among HA-RSV versus CO-RSV patients using conditional logistic regression. Escalation of respiratory support associated with RSV detection (day 0) from day -2 to day +4 was explored among HA-RSV patients. RESULTS: In total, 84 HA-RSV patients were matched to 160 CO-RSV patients. In HA-RSV patients, chronic kidney disease was more common, while chronic respiratory conditions and obesity were less common. HA-RSV patients were not more likely to be admitted to an ICU or require mechanical ventilation, but they more often required a higher level of care at discharge compared with CO-RSV patients (44% vs 14%, respectively). Also, 29% of evaluable HA-RSV patients required respiratory support escalation; these patients were older and more likely to have respiratory comorbidities, to have been admitted to intensive care, and to die during hospitalization. CONCLUSIONS: HA-RSV in adults may be associated with escalation in respiratory support and an increased level of support in living situation at discharge. Infection prevention and control strategies and RSV vaccination of high-risk adults could mitigate the risk of HA-RSV.

Effects of Integrative Cognitive Function Improvement Program on Cognitive Function, Oral Health, and Mental Health in Older People: A Randomized Clinical Trial.

We aimed to investigate the effects of an integrative cognitive function improvement program that combined existing cognitive, emotional, and physical therapies on cognitive function, oral health, and mental health in elder participants. Participants were classified into one of the following groups: cognitively normal (CN; n = 18), mild cognitive impairment (MCI; n = 17), and control (n = 17). An integrative cognitive function improvement program was administered to the CN and MCI groups for six weeks. To measure cognitive function, electroencephalogram (EEG) and cerebral blood flow (CBF) were evaluated, and to measure oral health, the O'Leary index, Löe & Silness index, tongue coating, unstimulated saliva flow rate, and oral muscle strength were measured. To measure mental health status, mental health, happiness and social support were measured. The CN and MCI groups showed a significant change in EEG-based indices for awareness level and physical stress. Regarding oral health, the O'Leary and the Löe & Silness index score decreased significantly in the CN and MCI groups. Saliva flow rate increased significantly in the CN and MCI groups. In regards to mental health, the happiness score increased post-intervention in the CN and MCI groups. In conclusion, the integrative cognitive function improvement program was effective in improving cognitive function, oral health, and mental health of elder people.

The clinical impact of multiple prevention strategies for respiratory syncytial virus infections in infants and high-risk toddlers in the United States.

BACKGROUND: Respiratory syncytial virus (RSV) remains a leading cause of medically-attended acute respiratory infection in infants and children. With multiple preventative interventions under development, accurate estimates of health care resource utilization are essential for policy decision making. METHODS: We developed a literature-based decision-tree model that estimated annual medically-attended RSV (MA-RSV) lower respiratory tract infection (LRTI) and non-LRTI episodes in the US for all infants and for high-risk toddlers. The model accounted for the gestational age and birth-month of infants, and the seasonal variation in RSV incidence. The impact of no prophylaxis, palivizumab, maternal vaccine, and long-acting monoclonal antibody (mAb) interventions was estimated. RESULTS: We estimated 1.23 million (range: 0.96 million-1.40 million) annual MA-RSV LRTI/non-LRTI episodes comprised of 1.19 million (range: 0.93 million-1.36 million) emergency department (ED) and outpatient visits, and 39,040 (range: 32,726-45,851) hospitalizations. Outpatient and ED visits were comprised of 586,034 (range: 430,595-718,868) LRTIs and 608,733 (range: 495,705-644,658) non-LRTIs. The long-acting mAb intervention resulted in the greatest number of averted outpatient and ED episodes (310,997 [53%] LRTIs; 284,305 [47%] non-LRTIs) and hospitalizations (21,845 [56%]). Full-term infants constitute the highest proportion of episodes across all interventions. CONCLUSIONS: MA-RSV disease is substantial in infants and high-risk toddlers. Long-acting mAbs are most effective at reducing the number of MA-RSV LRTI/non-LRTI episodes, and the only intervention that prevents disease in older infants (≥6 months old).

RSV testing practice and positivity by patient demographics in the United States: integrated analyses of MarketScan and NREVSS databases.

BACKGROUND: RSV-incidence estimates obtained from routinely-collected healthcare data (e.g., MarketScan) are commonly adjusted for under-reporting using test positivity reported in national Surveillance Systems (NREVSS). However, NREVSS lacks detail on patient-level characteristics and the validity of applying a single positivity estimate across diverse patient groups is uncertain. We aimed to describe testing practices and test positivity across subgroups of private health insurance enrollees in the US and illustrate the possible magnitude of misclassification when using NREVSS to correct for RSV under ascertainment. METHODS: Using billing records, we determined distributions of RSV-test claims and test positivity among a national sample of private insurance enrollees. Tests were considered positive if they coincided with an RSV-diagnosis. We illustrated the influence of positivity variation across sub-populations when accounting for untested acute respiratory infections. RESULTS: Most tests were for children (age 0-4: 65.8%) and outpatient encounters (78.3%). Test positivity varied across age (0-4: 19.8%, 5-17: 1.8%, adults: 0.7%), regions (7.6-16.1%), settings (inpatient 4.7%, outpatient 14.2%), and test indication (5.0-35.9%). When compared to age, setting or indication-specific positivity, bias due to using NREVSS positivity to correct for untested ARIs ranged from - 76% to 3556%. CONCLUSIONS: RSV-test positivity depends on the characteristics of patients for whom those tests were ordered. NREVSS-based correction for RSV-under-ascertainment underestimates the true incidence among children and overestimate rates among adults. Demographic-specific detail on testing practice and positivity can improve the accuracy of RSV-incidence estimates.

Rising childhood income inequality and declining Americans' health.

Morbidity and mortality are on the rise among Baby Boomers and younger cohorts. This study investigates whether this unfavorable health trend across birth cohorts 1925-1999 is related to rising income inequality Americans face during childhood. We use two nationally representative datasets: National Health and Nutrition Examination Surveys (NHANES) 1988-2018 and Panel Studies of Income Dynamics (PSID) 1968-2013, and two health outcomes: biomarkers of physiological dysregulation, and a chronic disease index. Childhood income inequality is measured by the average of the Gini index at the national level each birth cohort is exposed to between birth and age 18, where the Gini index from 1925 to 2016 is computed based on Internal Revenue Service income data. By merging childhood income inequality to individual level data from NHANES or PSID based on birth cohort, we find childhood income inequality is positively associated with the risk of physiological dysregulation in adulthood for all gender and racial groups in the NHANES data. It is also significantly related to the risk of chronic disease in the PSID data. This association is robust to controls for individual level childhood health and family background, adulthood socioeconomic and marital status, and contemporary macro socioeconomic factors. More importantly, childhood income inequality exposure explains a substantial amount of variation in these two health outcomes across cohorts, a pattern not observed for other early life exposures that display negative temporal trends similar to those for childhood income inequality. This study provides important evidence that income inequality experienced during childhood may have a long-lasting negative consequence for adult health, which partially explains the adverse health trends experienced by Baby Boomers and younger cohorts in the United States.

A Comprehensive Assessment Of Child Care Vaccination Laws Across The US.

All fifty US states and Washington, D.C., require children from birth through age five to be vaccinated against certain communicable diseases as a condition of attending child care settings such as day care, Head Start, preschools, pre-kindergarten, and other early childhood programs. However, the nuances and implementation of these laws vary greatly across jurisdictions. To date, a comprehensive analysis of all child care vaccination laws in the US has not been performed. We have developed the first compilation of child care vaccination laws across the US. This compilation is the culmination of an exhaustive examination of multiple components of the laws, such as which vaccines are required, provisions that enable unvaccinated children to temporarily attend child care until they are fully vaccinated, attendance provisions for unvaccinated students during an outbreak, methods of enforcement of vaccination policy, and child care personnel vaccination requirements. This comprehensive analysis provides a critical and foundational framework to inform policy makers and public health professionals involved in policy planning and implementation and policy research. It provides a benchmark for further evaluation of existing and future vaccination laws and their impact on vaccine coverage rates.
