Autochthonous Ascariasis, Mississippi, USA.

We describe a case of a 2-year-old child who expelled a single adult female Ascaris lumbricoides worm. The patient is from a rural county in Mississippi, USA, with no reported travel outside of the United States. The caregivers in the home practice good sanitation. Exposure to domestic pigs is the likely source of infection.

Considerations and Determinants of Discharge Decisions among Prenatal Substance Exposed Infants.

Limited research has examined a comprehensive set of predictors when evaluating discharge placement decisions for infants exposed to substances prenatally. Using a previously validated medical record data extraction tool, the current study examined prenatal substance exposure, infant intervention (i.e., pharmacologic, or non-pharmacologic), and demographic factors (e.g., race and ethnicity and rurality) as predictors of associations with discharge placement in a sample from a resource-poor state (N = 136; 69.9% Non-Hispanic White). Latent class analysis (LCA) was used to examine whether different classes emerged and how classes were differentially related to discharge placement decisions. Logistic regressions were used to determine whether each predictor was uniquely associated with placement decisions. Results of the LCA yielded a two-class solution comprised of (1) a Low Withdrawal Risk class, characterized by prenatal exposure to substances with low risk for neonatal abstinence syndrome (NAS) and non-pharmacologic intervention, and (2) a High Withdrawal Risk class, characterized by a high risk of NAS and pharmacologic intervention. Classes were not related to discharge placement decisions. Logistic regressions demonstrated that meth/amphetamine use during pregnancy was associated with greater odds of out of home placement above other substance types. Future research should replicate and continue examining the clinical utility of these classes.

Surveillance for Soil-Transmitted Helminths in High-Risk County, Mississippi, USA.

Recent reports of hookworm infection in Alabama, USA, has prompted surveillance in Mississippi, given the states' similar environmental conditions. We collected stool specimens from 277 children in Rankin County, Mississippi. Kato-Katz microscopic smear, agar plate culture, and quantitative PCR indicated no soil-transmitted helminths. Nevertheless, further surveillance in other high-risk Mississippi counties is warranted.

Risk Factors for Multisystem Inflammatory Syndrome in Children: A Case-control Investigation.

BACKGROUND: In a 2020 pilot case-control study using medical records, we reported that non-Hispanic Black children were more likely to develop multisystem inflammatory syndrome in children (MIS-C) after adjustment for sociodemographic factors and underlying medical conditions. Using structured interviews, we investigated patient, household, and community factors underlying MIS-C likelihood. METHODS: MIS-C case patients hospitalized in 2021 across 14 US pediatric hospitals were matched by age and site to outpatient controls testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within 3 months of the admission date. Caregiver interviews queried race/ethnicity, medical history, and household and potential community exposures 1 month before MIS-C hospitalization (case-patients) or after SARS-CoV-2 infection (controls). We calculated adjusted odds ratios (aOR) using mixed-effects multivariable logistic regression. RESULTS: Among 275 case patients and 496 controls, race/ethnicity, social vulnerability and patient or family history of autoimmune/rheumatologic disease were not associated with MIS-C. In previously healthy children, MIS-C was associated with a history of hospitalization for an infection [aOR: 4.8; 95% confidence interval (CI): 2.1-11.0]. Household crowding (aOR: 1.7; 95% CI: 1.2-2.6), large event attendance (aOR: 1.7; 95% CI: 1.3-2.1), school attendance with limited masking (aOR: 2.6; 95% CI: 1.1-6.6), public transit use (aOR: 1.8; 95% CI: 1.4-2.4) and co-resident testing positive for SARS-CoV-2 (aOR: 2.2; 95% CI: 1.3-3.7) were associated with increased MIS-C likelihood, with risk increasing with the number of these factors. CONCLUSIONS: From caregiver interviews, we clarify household and community exposures associated with MIS-C; however, we did not confirm prior associations between sociodemographic factors and MIS-C.

Impact of COVID-19 on Families with Children: Examining Sociodemographic Differences.

OBJECTIVE: The COVID-19 pandemic has exacerbated differences related to employment and family psychological health. However, empirical evidence examining COVID-19-linked differences concerning children and families remains scant. This study addresses this gap by examining sociodemographic differences associated with COVID-19 on family access to resources and family psychological health. METHOD: A telephone survey of 600 caregivers living in Mississippi was conducted from August 2020 to April 2021. Caregivers answered questions about levels of worry regarding themselves or their child contracting COVID-19 and impact of the pandemic on household income, access to resources, and family psychological health. RESULTS: Multivariate models demonstrated that Black caregivers (n = 273; 45.5%) had increased odds of agreeing that they worry about contracting COVID-19 (odds ratio [OR] = 2.57). Furthermore, as caregiver reported household annual income decreased, caregivers had increased odds of agreeing that they worry about contracting COVID-19 (OR = 1.16), lost job-related income (OR = 1.14), and had a hard time obtaining resources (OR = 1.16) because of the pandemic. No significant differences related to rural or urban residence were observed. CONCLUSION: The findings highlight the need for pragmatic responses that are attuned to differences by providing more equitable access to resources for families. The findings suggest that strategies addressing family worry, obtaining job-related income support, and helping families obtain tangible resources may positively affect family psychological health. As population changes in vaccination rates and COVID variants emerge, reassessment of family and community impact seems indicated. Limitations and future research directions are discussed.

A Pilot Comparison of Fixatives for Hookworm Real-time Polymerase Chain Reaction.

Polymerase chain reaction (PCR) is increasingly used in the diagnosis of soil-transmitted helminth infections. Despite this, few studies have evaluated the impact of different fecal fixatives on the outcome of fecal helminth qPCR analysis, and none have evaluated the effect of commercial parasitology fixatives commonly used in diagnostic laboratories. We fixed dog feces containing Ancylostoma spp. hookworm eggs in zinc polyvinyl alcohol (Zn-PVA) and Total-Fix, and with 70% ethanol (EtOH) as a control. DNA was extracted at timepoints 11, 33, 64, and 94 days and subjected to Ancylostoma spp. quantitative PCR (qPCR). A linear regression model was created to assess the effect of preservative types on the temporal change of qPCR quantification cycle number (Cq) values, accounting for variances among individual animals. Fixation in 70% EtOH least affected Cq values over 94 days. Total-Fix preservation yielded a higher Cq overall, but there was no significant difference compared with 70% EtOH fixation. Fixation in Zn-PVA resulted in significantly (P < 0.001) higher Cq values than 70% EtOH after only 33 days and loss of amplification at 64 days. Consistent with other helminth fixation studies, 70% EtOH performed well in preserving hookworm DNA over 94 days. Total-Fix provided a comparable alternative for qPCR analysis for hookworm. Fixation in Zn-PVA resulted in loss of detectable hookworm DNA at 64 days, as determined by qPCR.

Measuring and controlling medical record abstraction (MRA) error rates in an observational study.

BACKGROUND: Studies have shown that data collection by medical record abstraction (MRA) is a significant source of error in clinical research studies relying on secondary use data. Yet, the quality of data collected using MRA is seldom assessed. We employed a novel, theory-based framework for data quality assurance and quality control of MRA. The objective of this work is to determine the potential impact of formalized MRA training and continuous quality control (QC) processes on data quality over time. METHODS: We conducted a retrospective analysis of QC data collected during a cross-sectional medical record review of mother-infant dyads with Neonatal Opioid Withdrawal Syndrome. A confidence interval approach was used to calculate crude (Wald's method) and adjusted (generalized estimating equation) error rates over time. We calculated error rates using the number of errors divided by total fields ("all-field" error rate) and populated fields ("populated-field" error rate) as the denominators, to provide both an optimistic and a conservative measurement, respectively. RESULTS: On average, the ACT NOW CE Study maintained an error rate between 1% (optimistic) and 3% (conservative). Additionally, we observed a decrease of 0.51 percentage points with each additional QC Event conducted. CONCLUSIONS: Formalized MRA training and continuous QC resulted in lower error rates than have been found in previous literature and a decrease in error rates over time. This study newly demonstrates the importance of continuous process controls for MRA within the context of a multi-site clinical research study.

Active Surveillance With Seroprevalence-based Infection Rates Indicates Racial Disparities With Pediatric SARS-CoV-2 Requiring Hospitalization in Mississippi, March 2020-February 2021.

BACKGROUND: Racial disparities in SARS-CoV-2 infection, hospitalization, and multisystem inflammatory syndrome in children (MIS-C) have been reported. However, these reports have been based on incomplete data relying on passive reporting, unknown catchment populations, and unknown infection prevalence. We aimed to characterize population-based incidence of MIS-C and COVID-19 hospitalizations among non-Hispanic Black and White children using active surveillance based on seroprevalence-based cumulative incidence of pediatric SARS-CoV-2 infection in a defined catchment 16-county area of Mississippi. METHODS: Active, population-based surveillance for MIS-C and acute COVID-19 hospitalizations meeting clinical and laboratory criteria was conducted by adjudicating clinicians at the major pediatric referral hospital for Mississippi, University of Mississippi Medical Center, from March 2020, to February 2021. Race-stratified SARS-CoV-2 seroprevalence was estimated using convenience samples from persons <18 years to calculate cumulative SARS-CoV-2 infections in the population. RESULTS: Thirty-eight MIS-C cases and 74 pediatric acute COVID-19 hospitalizations were identified. Cumulative incidence of MIS-C was 4.7 times higher among Black compared with White children (40.7 versus 8.3 cases per 100,000 SARS-CoV-2 infections). Cumulative incidence of COVID-19 hospitalization was 62.3 among Black and 33.1 among White children per 100,000 SARS-CoV-2 infections. CONCLUSIONS: From the same catchment area, active surveillance, and cumulative incidence of infection estimated by seroprevalence, we show strikingly higher incidence of SARS-CoV-2-hospitalization and MIS-C in non-Hispanic Black children compared with White children before COVID-19 vaccination introduction in children. These disparities in SARS-CoV-2 manifestations cannot be accounted for by differences in exposure or testing. Targeted vaccine interventions will lessen disparities observed with SARS-CoV-2 manifestations in children.

An Analysis of Symptomatic Meniscal Re-Tear Incidence in Two Age Populations: Differences in Older versus Younger Adults.

A symptomatic meniscal tear is one of the most common problems treated by an orthopaedic surgeon. Treatment ranges from observation to complete meniscectomy. Prior research has shown that contact stresses increase within the joint compartment after partial meniscectomy, thus leading to arthritis of the compartment. The purpose of the current study was to determine the incidence of meniscal re-tears in two populations of patients and identify potential factors predisposing to re-tear. A retrospective review of our relational database identified 1,930 arthroscopic partial meniscectomies from 1993 to 2003. Meniscectomies were divided into two groups, 430 patients < 45 years of age (YOUNG) and 712 patients ≥ 45 (OLD). Age, onset date, Lysholm, Tegner, tear type, radial and circumferential location, as well as degree and location of chondromalacia, were analyzed. Of the YOUNG group, 1.16% experienced re-tears, versus 0.42% of the OLD group. From the younger re-tear group, 80% were chronic and 20% had grade 2 chondromalacia in one compartment. The YOUNG re-tear group was slightly more active with higher Tegner (5.6 vs. 4.3) and Lysholm (66.2 vs. 60) scores than the rest of the YOUNG group. The OLD re-tear group was less active with a lower Tegner (2.5 vs. 4.1) and Lysholm (62 vs. 66) score compared with the rest of the older group. In this study, patients under 45 years and with chronic tears had slightly higher incidence of re-tears. Results indicated that the lateral meniscus is more likely to re-tear.

Team Science Process Builds Research Coordinators' Voices in a National Pediatric Clinical Trials Network.

Geographically-dispersed teams have become the norm in clinical research collaborations. The Institutional Development Awards (IDeA) Program, first authorized by Congress in 1993 and managed by the National Institute of General Medical Sciences, has been developed for the purpose of broadening the geographic distribution of National Institutes of Health (NIH) funding for biomedical and behavioral research by enhancing the competitiveness for research funding of institutions located in states in which the aggregate success rate for grant applications to the NIH has historically been low. The IDeA States are composed of the Commonwealth of Puerto Rico and the following 23 states: Alaska, Arkansas, Delaware, Hawaii, Idaho, Kansas, Kentucky, Louisiana, Maine, Mississippi, Montana, Nebraska, Nevada, New Hampshire, New Mexico, North Dakota, Oklahoma, Rhode Island, South Carolina, South Dakota, Vermont, West Virginia, Wyoming. The Environmental influences on Child Health Outcomes (ECHO) research program's IDeA States Pediatric Clinical Trials Network (ISPCTN) was formed in 2016 with 24 sites within the IDeA states to provide clinical trial access to children in rural and underserved communities while building research capacity and infrastructure. In order to become effective, the network research coordinators used many methods to become more cohesive and productive. One of those methods was the use of Team Science.

Training as an Intervention to Decrease Medical Record Abstraction Errors Multicenter Studies.

Studies often rely on medical record abstraction as a major source of data. However, data quality from medical record abstraction has long been questioned. Electronic Health Records (EHRs) potentially add variability to the abstraction process due to the complexity of navigating and locating study data within these systems. We report training for and initial quality assessment of medical record abstraction for a clinical study conducted by the IDeA States Pediatric Clinical Trials Network (ISPCTN) and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Neonatal Research Network (NRN) using medical record abstraction as the primary data source. As part of overall quality assurance, study-specific training for medical record abstractors was developed and deployed during study start-up. The training consisted of a didactic session with an example case abstraction and an independent abstraction of two standardized cases. Sixty-nine site abstractors from thirty sites were trained. The training was designed to achieve an error rate for each abstractor of no greater than 4.93% with a mean of 2.53%, at study initiation. Twenty-three percent of the trainees exceeded the acceptance limit on one or both of the training test cases, supporting the need for such training. We describe lessons learned in the design and operationalization of the study-specific, medical record abstraction training program.

A Meta-Analysis of Arthroscopic Meniscal Repair: Inside-Out versus Outside-In versus All-Inside Techniques.

Meniscal repair has been introduced to preserve knee function and limit the accelerated degenerative changes associated with meniscal tissue resection. Arthroscopic techniques have evolved to improve morbidity. However, there are few clinical outcome studies in the peer-reviewed literature that compare the use of these approaches. Therefore, our purpose was to perform a meta-analysis of the existing literature on arthroscopic meniscal repair techniques. Specifically, we evaluated differences in: (1) operating time; (2) incidence of postoperative meniscal healing; (3) functional outcomes, using various scoring systems; and (4) incidence of complications. We searched the peer-reviewed literature using SCOPUS, Medline, EMBASE, and Web of Science. Eight studies were eligible for the meta-analysis. These included one prospective, randomized trial (level I), three prospective, comparative studies (level II), and four retrospective, comparative studies (level III). There were a total of 476 patients who had a mean follow-up between 3 and 156 months. When evaluating objective outcomes, the inside-out technique had a significantly higher mean operating time than the all-inside technique. The inside-out and all-inside techniques had comparable meniscal healing rates, but the outside-in repair had a significantly higher rate of meniscal healing than the all-inside repair. Upon assessment of functional outcomes, the inside-out and all-inside methods had comparable International Knee Documentation Committee and Tegner activity scores, but the all-inside method had greater improvements in Lysholm scores. The inside-out and all-inside repairs had similar overall complication rates. All-inside repair may demonstrate lower operating times, but the outside-in repair may have superior meniscal healing rates. Functional outcomes are overall comparable between the techniques. However, there are limited clinical data on the outcome differences between these procedures, and further comparative studies with longer follow-up are needed.
