A Comparison of Obstetric Interventions and Outcomes Between Black and White Patients at an Urban Tertiary Medical Center

The objective of the study is to evaluate whether rates of selected labor and delivery interventions and severe maternal morbidity (SMM) differ between Black and White pregnant patients. This retrospective observational cohort study included all Black or White pregnant patients who delivered at the University of Chicago Medical Center between January 2015 and December 2019. Data queried included demographic information, antepartum complications, preterm interventions, labor and delivery events, and neonatal outcomes. SMM was a composite outcome, including intensive care unit admission, blood transfusion, hysterectomy, eclampsia, cardiac arrest, or death. In total, 10,885 parturients (9001 Black and 1884 White) and 11,211 neonates (9254 born to Black and 1957 to White patients) were included in the study. Black patients were more likely to have preterm labor (3.51% vs. 1.86%, p = 0.0002) and no prenatal care (17.83% vs. 4.05%, p < 0.0001). There was no significant difference in the administration of magnesium sulfate for fetal neuroprotection (Black 44.78% vs. White 49.32%, p = 0.48) or antenatal corticosteroids (Black 67.83% vs. White 71.98%, p = 0.28) among those with preterm delivery. There was no significant difference in SMM (Black 2.24% vs. White 2.44%, p = 0.60), and SMM rates decreased over time (OR 0.79 per year, 95% CI: 0.72-0.87, p < 0.0001) for all patients. Black patients had more pregnancy complications, but their complications were addressed with similar rates of obstetrical interventions. In a high-resource setting, there was no difference in rates of SMM when compared to White patients.

Novel paradigm enables accurate monthly gestational screening to prevent congenital toxoplasmosis and more

Background

Congenital toxoplasmosis is a treatable, preventable disease, but untreated causes death, prematurity, loss of sight, cognition and motor function, and substantial costs worldwide.

Methods/Findings

In our ongoing USA feasibility/efficacy clinical trial, data collated with other ongoing and earlier published results proved high performance of an Immunochromatographic-test(ICT) that enables accurate, rapid diagnosis/treatment, establishing new paradigms for care. Overall results from patient blood and/or serum samples tested with ICT compared with gold-standard-predicate-test results found ICT performance for 4606 sera/1876 blood, 99.3%/97.5% sensitive and 98.9%/99.7% specific. However, in the clinical trial the FDA-cleared-predicate test initially caused practical, costly problems due to false-positive-IgM results. For 58 persons, 3/43 seronegative and 2/15 chronically infected persons had false positive IgM predicate tests. This caused substantial anxiety, concerns, and required costly, delayed confirmation in reference centers. Absence of false positive ICT results contributes to solutions: Lyon and Paris France and USA Reference laboratories frequently receive sera with erroneously positive local laboratory IgM results impeding patient care. Therefore, thirty-two such sera referred to Lyon's Reference laboratory were ICT-tested. We collated these with other earlier/ongoing results: 132 of 137 USA or French persons had false positive local laboratory IgM results identified correctly as negative by ICT. Five false positive ICT results in Tunisia and Marseille, France, emphasize need to confirm positive ICT results with Sabin-Feldman-Dye-test or western blot. Separate studies demonstrated high performance in detecting acute infections, meeting FDA, CLIA, WHO ASSURED, CEMark criteria and patient and physician satisfaction with monthly-gestational-ICT-screening.

Conclusions/Significance

This novel paradigm using ICT identifies likely false positives or raises suspicion that a result is truly positive, rapidly needing prompt follow up and treatment. Thus, ICT enables well-accepted gestational screening programs that facilitate rapid treatment saving lives, sight, cognition and motor function. This reduces anxiety, delays, work, and cost at point-of-care and clinical laboratories.

Author’s Summary

Toxoplasmosis is a major health burden for developed and developing countries, causing damage to eyes and brain, loss of life and substantial societal costs. Prompt diagnosis in gestational screening programs enables treatment, thereby relieving suffering, and leading to > 14-fold cost savings for care. Herein, we demonstrate that using an ICT that meets WHO ASSURED-criteria identifying persons with/without antibody to Toxoplasma gondii in sera and whole blood with high sensitivity and specificity, is feasible to use in USA clinical practice. We find this new approach can help to obviate the problem of detection of false positive anti- T.gondii IgM results for those without IgG antibodies to T.gondii when this occurs in present, standard of care, predicate USA FDA cleared available assays. Thus, this accurate test facilitates gestational screening programs and a global initiative to diagnose and thereby prevent and treat T.gondii infection. This minimizes likelihood of false positives (IgG and/or IgM) while maintaining maximum sensitivity. When isolated IgM antibodies are detected, it is necessary to confirm and when indicated continue follow up testing in ∼2 weeks to establish seroconversion. Presence of a positive ICT makes it likely that IgM is truly positive and a negative ICT makes it likely that IgM will be a false positive without infection. These results create a new, enthusiastically-accepted, precise paradigm for rapid diagnosis and validation of results with a second-line test. This helps eliminate alarm and anxiety about false-positive results, while expediting needed treatment for true positive results and providing back up distinguishing false positive tests.

Building Programs to Eradicate Toxoplasmosis Part III: Epidemiology and Risk Factors

Purpose of Review

Review comprehensive data on rates of toxoplasmosis in Panama and Colombia.

Recent Findings

Samples and data sets from Panama and Colombia, that facilitated estimates regarding seroprevalence of antibodies to Toxoplasma and risk factors, were reviewed.

Summary

Screening maps, seroprevalence maps, and risk factor mathematical models were devised based on these data. Studies in Ciudad de Panamá estimated seroprevalence at between 22 and 44%. Consistent relationships were found between higher prevalence rates and factors such as poverty and proximity to water sources. Prenatal screening rates for anti-Toxoplasma antibodies were variable, despite existence of a screening law. Heat maps showed a correlation between proximity to bodies of water and overall Toxoplasma seroprevalence. Spatial epidemiological maps and mathematical models identify specific regions that could most benefit from comprehensive, preventive healthcare campaigns related to congenital toxoplasmosis and Toxoplasma infection.

Building Programs to Eradicate Toxoplasmosis Part II: Education

Purpose of Review

Review work to create and evaluate educational materials that could serve as a primary prevention strategy to help both providers and patients in Panama, Colombia, and the USA reduce disease burden of Toxoplasma infections.

Recent Findings

Educational programs had not been evaluated for efficacy in Panama, USA, or Colombia.

Summary

Educational programs for high school students, pregnant women, medical students and professionals, scientists, and lay personnel were created. In most settings, short-term effects were evaluated. In Panama, Colombia, and USA, all materials showed short-term utility in transmitting information to learners. These educational materials can serve as a component of larger public health programs to lower disease burden from congenital toxoplasmosis. Future priorities include conducting robust longitudinal studies of whether education correlates with reduced adverse disease outcomes, modifying educational materials as new information regarding region-specific risk factors is discovered, and ensuring materials are widely accessible.

The changing face of publicly funded employment services

The federal-state vocational rehabilitation (VR) program has been a significant stream of funding for individuals with traumatic brain injury (TBI). However, the success of this traditional rehabilitation approach with people with brain injuries remains limited. Recently, the use of specialized employment services, such as Supported Employment, has proven to be far more effective, but funding for this population remains limited. In addition, even individuals who receive specialized employment services often require more intensive, ongoing supports to remain employed. In response, many states have developed innovative services and approaches that are improving the placement and retention rates of individuals with TBI. In this article, the authors provide an overview of selected federal funding initiatives related to the provision of employment services to people with brain injuries, including recent amendments to the Rehabilitation Act. The article also highlights progressive state employment policies and makes suggestions for creative use of government employment monies.

The legal and risk management conundrum of telemedicine

A store-and-forward teledermatology service was established between two general practices and the department of plastic surgery at Derriford Hospital in Plymouth. An academic lawyer and an expert in risk management made an assessment of the service. They looked at the following issues: medicolegal problems; security; confidentiality; and risk. None of them was considered insoluble and there is no reason why such issues should prevent the National Health Service from developing telemedicine services. All organizations considering telemedicine need to ensure that the proposed telemedicine service satisfies the issues raised in this study.

Survey of case manager training needs in traumatic brain injury

The results of 138 surveys assessing the training needs of case managers in the area of traumatic brain injury were analysed. Sixty-six per cent of the respondents were case managers working primarily with adults in a variety of work settings. Respondents rated working with families, vocational rehabilitation, and community re-entry as the top three areas for training. Mild traumatic brain injury, paediatric traumatic brain injury, neuropsychological assessment, and medicolegal aspects received the highest rankings by case managers with more than 8 years experience. The need for certification of case managers in specialty areas was supported by 83% of all respondents.

The consequences and effectiveness of intubation in the palliation of dysphagia due to benign and malignant strictures affecting the oesophagus

In a study of 66 patients intubated to relieve dysphagia, 52 (79 per cent) survived the procedure and were discharged home. Of these, 23 (44 per cent) developed further dysphagia due to tube dysfunction, and 19 patients (37 per cent) were readmitted for further procedures to restore swallowing. With early intervention, the periods of dysphagia were short and the palliation so achieved was effective. Overall, intubation proved to be an effective method of relieving dysphagia in patients unsuitable for curative treatment.
