A Cautionary Tale: Malaligned Incentives in Total Hip and Knee Arthroplasty Payment Model Reforms Threaten Promising Innovation and Access to Care.

Over the past several years, there have been notable changes and controversies involving Medicare reimbursement for total hip (THA) and total knee arthroplasty (TKA). We have seen the development and implementation of experimental bundled payment model pilot programs goals of improving quality and decreasing overall costs of care during the last decade. Many orthopaedic surgeons have embraced these programs and have demonstrated the ability to succeed in these new models by implementing strategies, such as preservice optimization, to shift care away from inpatient or postdischarge settings and reduce postoperative complications.

A rare presentation of infectious mononucleosis: cholestatic hepatitis with hyperbilirubinemia.

Introduction: Epstein-Barr virus infection with mononucleosis is the most common presentation in young adults. Most infections are self-limited, although in a few cases complications can include serious conditions such as lymphoproliferative disorders or in less severe cases, mild hepatitis.

Case Report: We present an unusual case of a young male with no liver disease, who presented with markedly elevated cholestatic pattern hyperbilirubinemia, as well as hepatitis.

The Differential Effect of COVID on Total Joint Arthroplasty Between Hospital and Ambulatory Surgery Centers/Hospital Outpatient Departments: A Michigan Arthroplasty Registry Collaborative Quality Initiative Analysis.

Background: Coronavirus disease (COVID) created unprecedented challenges, especially for high-volume elective subspecialties like total joint arthroplasty. Limited inpatient capacity and resource conservation led to new outpatient selection criteria and site of service changes. As a Michigan Arthroplasty Registry Quality Collaborative Initiative quality project, demographic changes, complications, and differential effects on inpatient vs outpatient centers pre- and post-COVID were analyzed.

Predominant Intractable Nausea in the Diagnosis of Bulbar Myasthenia Gravis: A Case Study and Review of Literature.

Gastrointestinal (GI)-predominant myasthenia gravis (MG) is rare and presents a complex clinical scenario. We report the case of a 73-year-old female with dysphagia and intractable nausea found to have bulbar MG. Her symptoms persisted despite conventional MG management with plasma exchange therapy and anticholinergics.

Mesenteric fat cryolipolysis attenuates insulin resistance in the Ossabaw swine model of the metabolic syndrome.

Background: The rising prevalence of insulin resistance (IR), metabolic syndrome, and type 2 diabetes are associated with increases in abdominal mesenteric fat. Adipocytes are sensitive to low temperatures, making cryolipolysis of mesenteric fat an attractive treatment modality to potentially reduce IR.

Objectives: We aimed to determine whether (1) cryolipolysis is safe in reducing the volume of the mesenteric fat and (2) reduction in mesenteric fat volume reduces indices of IR and glycemic dysfunction.

Microstructure and electrochemical behavior of contemporary Ti6Al4V implant alloys.

Ti6Al4V is the most common titanium alloy within the biomaterial field. While material standards for different variations of this alloy exist, there are only minimal requirements with respect to its microstructure which is directly related to the alloy's properties. Thus, a better understanding of the Ti6Al4V microstructure of common contemporary implant components and its effect on the electrochemical behavior is needed; including additively manufactured (AM) devices.

Length of stay and cost of care associated with admissions for atrial fibrillation among patients with cancer.

Background: The aim of this study is to assess the burden of AF-related hospitalizations inclusive of inflation-adjusted cost-of-care and length-of-stay (LOS) among cancer patients and the impact of direct current cardioversion (DCCV) on these outcomes.

Methods: Using the National Inpatient Sample (NIS), patients hospitalized with either a primary or secondary diagnosis of AF and comorbid cancer were identified and both cost of hospitalization and LOS were evaluated for each group. Subgroup analyses were performed for specific cancer types (breast, lung, colon, prostate and lymphoma), and those receiving DCCV.

Serotonin Syndrome Precipitated by the Use of Cocaine and Fentanyl.

Serotonin syndrome (SS) is a condition that occurs following the administration of serotonergic drugs. The syndrome is classically associated with the simultaneous administration of two serotonergic agents. Herein, we present a unique case of SS precipitated by cocaine and fentanyl in conjunction with previously prescribed oxycodone/paracetamol, trazodone, and mirtazapine.

John N. Insall Award: MARCQI's Pain-Control Optimization Pathway (POP): Impact of Registry Data and Education on Opioid Utilization.

Background: In 2019, the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) recommended an evidence-based opioid pain pathway to participating physicians and hospitals for patients undergoing total joint arthroplasty (TJA). The purpose of this study was to determine if the education could influence and have lasting effects on the prescribing patterns for TJA patients.

Methods: Using the MARCQI database, the number of oral morphine equivalents (OMEs) prescribed at discharge were collected from January 2018 through December 2019 for all primary arthroplasty procedures.

Rapid Reductions in Breast Density following Tamoxifen Therapy as Evaluated by Whole-Breast Ultrasound Tomography.

Purpose: Women whose mammographic breast density declines within 12-18 months of initiating tamoxifen for chemoprevention or adjuvant treatment show improved therapeutic responses compared with those whose density is unchanged. We tested whether measuring changes in sound speed (a surrogate of breast density) using ultrasound tomography (UST) could enable rapid identification of favorable responses to tamoxifen.

Methods: We evaluated serial density measures at baseline and at 1 to 3, 4 to 6, and 12+ months among 74 women (aged 30-70 years) following initiation of tamoxifen for clinical indications, including an elevated risk of breast cancer (20%) and diagnoses of in situ (39%) or invasive (40%) breast carcinoma, enrolled at Karmanos Cancer Institute and Henry Ford Health System (Detroit, MI, USA).

Percutaneous mechanical thrombectomy in a real-world pulmonary embolism population: Interim results of the FLASH registry.

Objectives: The FlowTriever All-Comer Registry for Patient Safety and Hemodynamics (FLASH) is a prospective multi-center registry evaluating the safety and effectiveness of percutaneous mechanical thrombectomy for treatment of pulmonary embolism (PE) in a real-world patient population (NCT03761173). This interim analysis reports outcomes for the first 250 patients enrolled in FLASH.

Background: High- and intermediate-risk PEs are characterized by high mortality rates, frequent readmissions, and long-term sequelae.

Using a Direct Observation Tool (TOC-CEX) to Standardize Transitions of Care by Residents at a Community Hospital.

High-quality transitions of care are crucial for patient safety in hospitals, yet few undergraduate curricula include transition-of-care training. In 2012, the Wayne State University Office of Graduate Medical Education (WSUGME) required its residency programs to use the SAIF-IR mnemonic (summary, active issues, if-then contingency planning, follow-up activities, interactive questioning, readback) to ensure accurate and uniform handoffs. Subsequent program evaluations indicated that resident awareness and adoption of the mnemonic at our primary clinical site, Ascension Providence Rochester Hospital (APRH), could be improved.

An Objective Structured Clinical Examination Case for Opioid Management: Standardized Patient Ratings of Communication Skills as a Predictor of Systems-Based Practice Scores.

The Wayne State University Office of Graduate Medical Education (WSUGME) uses an objective structured clinical examination (OSCE) to assess its programs' contribution to enhancing residents' communication skills. In response to revisions in Michigan's opioid-prescribing mandates in 2017, WSUGME developed a pain management case in collaboration with faculty and the Wayne State University School of Medicine to educate residents about these mandates while gauging their skills in Systems-Based Practice (SBP), an Accreditation Council for Graduate Medical Education Core Competency. This study examined whether resident OSCE performance predicted year-end milestones scores in SBP1 (coordinates patient care within various health care delivery settings), SBP2 (works in interdisciplinary teams to enhance patient safety and improve patient care quality), and SBP3 (practices and advocates for cost-effective, responsible care).

A Case of Immune Thrombocytopenia After BNT162b2 mRNA COVID-19 Vaccination.

BACKGROUND Immune thrombocytopenic purpura (ITP) is an immune response that destroys platelets and increases the risk of bleeding, which can range from bruising to intracranial hemorrhage. ITP is a known complication of coronavirus disease 2019 (COVID-19). In the first studies of the BNT162b2 messenger RNA (mRNA) COVID-19 vaccine, there were no reports of ITP and the incidence of serious adverse events (AEs) was low overall.

Clinical Course of COVID-19 in Identical Twins.

The rapid outbreak of coronavirus disease 19 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to infection with variable clinical presentations and a wide clinical spectrum. The disease was first reported in Wuhan, China in 2019 and has rapidly spread worldwide. Despite reports of dynamic changes in disease progression, clinical predictors of disease severity have been difficult to identify.

Quantifying Patient Engagement in Total Joint Arthroplasty Using Digital Application-Based Technology.

Background: Digital patient engagement has been suggested as a mean to increase patient activation and patient satisfaction after total joint arthroplasty. The purpose of this study was to assess patient engagement with application-based educational tools and to explore what content was most useful to patients in the perioperative period surrounding total hip arthroplasty (THA) and total knee arthroplasty (TKA), respectively.

Methods: Patients undergoing THA and TKA between October 2017 and January 2020 were enrolled to use an application-based digital technology.

Cryoablation and Immunotherapy for Breast Cancer: Overview and Rationale for Combined Therapy.

Cryoablation is a well-tolerated outpatient procedure that has been used to treat metastatic sites as well as small breast cancers in patients who are considered poor candidates for surgery. Recent studies suggest that cell disruption caused by cryoablation may increase the expression and immunogenicity of tumor neoantigens, which could enhance the ability of the immune system to recognize and attack cancer cells at both local and distant sites. Such an approach might broaden the role of immunotherapy for the treatment of breast cancer, which has previously demonstrated limited response to these agents, likely owing to the modest immunogenicity of most breast cancer subtypes.

Cryoablation for Palliation of Painful Bone Metastases: The MOTION Multicenter Study.

Purpose: To assess the clinical effectiveness of cryoablation for palliation of painful bone metastases.

Materials And Methods: MOTION (Multicenter Study of Cryoablation for Palliation of Painful Bone Metastases) (ClinicalTrials.gov NCT02511678) was a multicenter, prospective, single-arm study of adults with metastatic bone disease who were not candidates for or had not benefited from standard therapy, that took place from February 2016 to March 2018.

Clinical judgement in chest pain: a case report.

Background: Cardiac stress testing is a validated diagnostic tool to assess symptomatic patients with intermediate pretest probability of coronary artery disease (CAD). However, in some cases, the cardiac stress test may provide inconclusive results and the decision for further workup typically depends on the clinical judgement of the physician. These decisions can greatly affect patient outcomes.
