Integrating Social Determinants of Health in Machine Learning-Driven Decision Support for Diabetes Case Management: Protocol for a Sequential Mixed Methods Study.

Background: The use of both clinical factors and social determinants of health (SDoH) in referral decision-making for case management may improve optimal use of resources and reduce outcome disparities among patients with diabetes.

Objective: This study proposes the development of a data-driven decision-support system incorporating interactions between clinical factors and SDoH into an algorithm for prioritizing who receives case management services. The paper presents a design for prediction validation and preimplementation assessment that uses a mixed methods approach to guide the implementation of the system.

Semantically oriented EHR navigation with a patient specific knowledge base and a clinical context ontology.

Widespread adoption of electronic health records (EHR) in the U.S. has been followed by unintended consequences, overexposing clinicians to widely reported EHR limitations.

The University of Alabama at Birmingham COVID-19 Collaborative Outcomes Research Enterprise: Developing an institutional learning health system in response to the global pandemic.

Introduction: As a local response to the COVID-19 global pandemic, the University of Alabama at Birmingham (UAB) established the UAB COVID-19 Collaborative Outcomes Research Enterprise (CORE), an institutional learning health system (LHS) to achieve an integrated health services outcomes and research response.

Methods: We developed a network of expertise and capabilities to rapidly develop and deploy an institutional-level interdisciplinary LHS. Based upon a scoping review of the literature and the Knowledge to Action Framework, we adopted a LHS framework identifying contributors and components necessary to developing a system within and between the university academic and medical centers.

Contribution of warm habitat to cold-water fisheries.

A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. However, incorporating the dynamic needs of mobile species into conservation strategies remains a challenge, particularly in the context of climate adaptation planning. For cold-water fishes, it is widely assumed that maximum temperatures are limiting and that summer data alone can predict refugia and population persistence.

Development of a Coronavirus Disease 2019 (COVID-19) Application Ontology for the Accrual to Clinical Trials (ACT) network.

Clinical data networks that leverage large volumes of data in electronic health records (EHRs) are significant resources for research on coronavirus disease 2019 (COVID-19). Data harmonization is a key challenge in seamless use of multisite EHRs for COVID-19 research. We developed a COVID-19 application ontology in the national Accrual to Clinical Trials (ACT) network that enables harmonization of data elements that are critical to COVID-19 research.

Rapid implementation and improvement of a virtual student placement model in response to the COVID-19 pandemic.

Practice-based learning via clinical placement is a core part of a physiotherapy degree with the Chartered Society of Physiotherapy requiring completion of 1000 placement hours over a preregistration degree programme. In April 2020, as a result of the COVID-19 pandemic and subsequent lockdown Connect Health had to cancel 10 student placements as we transitioned to virtual consultations for all clinics. This cancellation of student placements was replicated across the nation with many Higher Education Institutes reporting a backlog of student placements.

Classifying Clinical Trial Eligibility Criteria to Facilitate Phased Cohort Identification Using Clinical Data Repositories.

A major challenge in using electronic health record repositories for research is the difficulty matching subject eligibility criteria to query capabilities of the repositories. We propose categories for study criteria corresponding to the effort needed for querying those criteria: "easy" (supporting automated queries), mixed (initial automated querying with manual review), "hard" (fully manual record review), and "impossible" or "point of enrollment" (not typically in health repositories). We obtained a sample of 292 criteria from 20 studies from ClinicalTrials.

Utilizing transesophageal echocardiography for placement of pulmonary artery catheters.

Objective: Pulmonary artery catheters (PACs) have routinely been positioned by wedging into the pulmonary artery before pulling back 1-2 centimeters or advancing the PAC several centimeters after achieving a pulmonary artery waveform. A rare, major complication is pulmonary artery rupture. This study presents transesophageal echocardiography (TEE) for PAC placement by leaving the catheter tip at the one o'clock position, upper window short-axis view of the ascending aorta at the bifurcation of the pulmonary artery (TEE distance).

Reducing Postoperative Bleeding After Craniosynostosis Repair Utilizing a Low-Dose Transexamic Acid Infusion Protocol.

Background: Craniosynostosis surgery is associated with large volume blood loss and the need for blood transfusion. Recently, the use of tranexamic acid (TXA) has been demonstrated to be helpful in reducing perioperative blood loss in many pediatric procedures. This study used a low-dose pharmacokinetic TXA dosing protocol and assessed its ability to limit perioperative blood loss for craniosynostosis repairs.

Sedation and Analgesia for Dressing Change: A Survey of American Burn Association Burn Centers.

Pain and sedation management for patients undergoing burn dressing change can be challenging. Variations appear to exist in the selection of medications before and during burn dressing change. To determine if institutional variations exist in pain and sedation management for burn dressing change, an online survey was sent to ABA Burn Center nurses and physicians.

Efficient identification of nationally mandated reportable cancer cases using natural language processing and machine learning.

Objective: To help cancer registrars efficiently and accurately identify reportable cancer cases.

Material And Methods: The Cancer Registry Control Panel (CRCP) was developed to detect mentions of reportable cancer cases using a pipeline built on the Unstructured Information Management Architecture - Asynchronous Scaleout (UIMA-AS) architecture containing the National Library of Medicine's UIMA MetaMap annotator as well as a variety of rule-based UIMA annotators that primarily act to filter out concepts referring to nonreportable cancers. CRCP inspects pathology reports nightly to identify pathology records containing relevant cancer concepts and combines this with diagnosis codes from the Clinical Electronic Data Warehouse to identify candidate cancer patients using supervised machine learning.

Federated Aggregate Cohort Estimator (FACE): an easy to deploy, vendor neutral, multi-institutional cohort query architecture.

Cross-institutional data sharing for cohort discovery is critical to enabling future research. While particularly useful in rare diseases, the ability to target enrollment and to determine if an institution has a sufficient number of patients is valuable in all research, particularly in the initiation of projects and collaborations. An optimal technology solution would work with any source database with minimal resource investment for deployment and would meet all necessary security and confidentiality requirements of participating organizations.

Distributed Health Outcome Monitoring and Evaluation Using i2b2.

There is a pressing need for better tools to support comparative effectiveness research (CER) on a national scale. In addition, little is known about within-class outcome disparities for commonly used cardiovascular and diabetes medications. In this presentation, we will describe our experience implementing a new i2b2 cell, the Health Outcome Monitoring and Evaluation Cell (HOME), at 5 collaborating Clinical Translational Science Award sites (CTSAs) in the U.

Supervised exercise plus acupuncture for moderate to severe knee osteoarthritis: a small randomised controlled trial.

Objectives: Although total knee replacement (TKR) is cost effective and successful in most cases, patient-reported outcome measures demonstrate 20% of people remain unsatisfied at 1 year after a technically successful procedure. Our group has previously shown that patients with severe knee osteoarthritis (OA) awaiting surgery can achieve a short-term reduction in symptom severity when treated with acupuncture, and that a trend towards improved walking distance, as a measure of function, is achieved with preoperative supervised exercise. The aim of this study was to evaluate the effect of combined acupuncture and physiotherapy on preoperative and postoperative pain and function.

Development and validation of a pictorial nausea rating scale for children.

Objective: The lack of a widely used, validated measure limits pediatric nausea management. The goal of this study was to create and validate a pictorial scale with regular incremental levels between scores depicting increasing nausea intensity.

Methods: A pictorial nausea scale of 0 to 10 with 6 faces (the Baxter Retching Faces [BARF] scale) was developed in 3 stages.

Direct delivery of MIF morpholinos into the zebrafish otocyst by injection and electroporation affects inner ear development.

In recent years, electroporation has become a popular technique for in vivo transfection of DNA, RNA, and morpholinos into various tissues, including the eye, brain, and somites of zebrafish. The advantage of electroporation over other methods of genetic manipulation is that specific tissues can be targeted, both spatially and temporally, for the introduction of macromolecules by the application of electrical current. Here we describe the use of electroporation for transfecting mif and mif-like morpholinos into the tissues of the developing inner ear of the zebrafish.

Uniform cell seeding and generation of overlapping gradient profiles in a multiplexed microchamber device with normally-closed valves.

Generation of stable soluble-factor gradients in microfluidic devices enables studies of various cellular events such as chemotaxis and differentiation. However, many gradient devices directly expose cells to constant fluid flow and that can induce undesired responses from cells due to shear stress and/or wash out of cell-secreted molecules. Although there have been devices with flow-free gradients, they typically generate only a single condition and/or have a decaying gradient profile that does not accommodate long-term experiments.

The effect of intraoperative dexmedetomidine on postoperative analgesia and sedation in pediatric patients undergoing tonsillectomy and adenoidectomy.

Background: The immediate postoperative period after tonsillectomy and adenoidectomy, one of the most common pediatric surgical procedures, is often difficult. These children frequently have severe pain but postoperative airway edema along with increased sensitivity to the respiratory-depressant effects of opioids may result in obstructive symptoms and hypoxemia. Opioid consumption may be reduced by nonsteroidal antiinflammatory drugs, but these drugs may be associated with increased bleeding after this operation.

Effects of human immunodeficiency virus status on trauma outcomes: a review of the national trauma database.

Background: The prevalence of human immunodeficiency virus (HIV) is disproportionately elevated in trauma patients. Although HIV traditionally has been associated with poorer outcomes among the critically ill, recent evidence suggests that the outcomes of surgical patients have improved with the greater use of antiretroviral regimens. The purpose of this study was to utilize the National Trauma Data Bank (NTDB) to examine the impact of HIV on surgical outcomes in a large group of trauma patients.

Ankle-brachial index performance among internal medicine residents.

The ankle-brachial index (ABI) is the standard test used in clinical practice to detect peripheral artery disease (PAD) and is a powerful predictor of adverse cardiovascular outcomes. This study sought to measure the baseline knowledge of the ABI test among a sample of internal medicine residents and to examine the impact of an educational intervention on performance of the test. A total of 29 residents were asked to perform three tasks, with the performance of each task being assessed using a point-based scoring system: measure an ABI on a normal volunteer (15 points), calculate the ABI based on data from a hypothetical patient (3 points), and interpret a range of ABI values (6 points).

Impact of the 80-hour work week on mortality and morbidity in trauma patients: an analysis of the National Trauma Data Bank.

Introduction: The implementation of the 80-h work week restrictions implemented by the Accreditation Council for Graduate Medical Education (ACGME) in July 2003 were intended, in part, to improve patient outcomes by reducing fatigue-related resident errors. Although concerns were raised regarding the possibility for increased error due to decreased continuity of patient care, recent studies have shown no significant change in mortality or complication rates since the onset of these new restrictions. This study is the first to examine the effects of the 80-h work week on mortality in trauma patients on a national level.

Finding the way to a better death: an evaluation of palliative care referral tools.

The authors of this study sought to identify a tool for assessing and referring dying inpatients to palliative care. Six currently available tools were evaluated to determine how well each tool incorporated 16 clinical criteria that indicate the need for palliative care. Scientific evidence supporting each instrument and the tools' ease of use at patients' bedside also was assessed.
