AbstractPersistent chest pain (PCP) following acute COVID‐19 infection is a commonly reported symptom with an unclear etiology, making its management challenging. This scoping review aims to address the knowledge gap surrounding the characteristics of PCP following COVID‐19, its causes, and potential treatments. This is a scoping review of 64 studies, including observational (prospective, retrospective, cross‐sectional, case series, and case–control) and one quasi‐experimental study, from databases including Embase, PubMed/MEDLINE, Cochrane CENTRAL, Google Scholar, Cochrane Database of Systematic Reviews, and Scopus. Studies on patients with PCP following mild, moderate, and severe COVID‐19 infection were included. Studies with patients of any age, with chest pain that persisted following acute COVID‐19 disease, irrespective of etiology or duration were included. A total of 35 studies reported PCP symptoms following COVID‐19 (0.24%–76.6%) at an average follow‐up of 3 months or longer, 12 studies at 1–3 months and 17 studies at less than 1‐month follow‐up or not specified. PCP was common following mild—severe COVID‐19 infection, and etiology was mostly not reported. Fourteen studies proposed potential etiologies including endothelial dysfunction, cardiac ischemia, vasospasm, myocarditis, cardiac arrhythmia, pneumonia, pulmonary embolism, postural tachycardia syndrome, or noted cardiac MRI (cMRI) changes. Evaluation methods included common cardiopulmonary tests, as well as less common tests such as flow‐mediated dilatation, cMRI, single‐photon emission computed tomography myocardial perfusion imaging, and cardiopulmonary exercise testing. Only one study reported a specific treatment (sulodexide). PCP is a prevalent symptom following COVID‐19 infection, with various proposed etiologies. Further research is needed to establish a better understanding of the causes and to develop targeted treatments for PCP following COVID‐19.

AbstractBackgroundAs the proportion of women and individuals who are underrepresented in medicine slowly rises, disparities persist in numerous arenas and specialties. In physical medicine and rehabilitation (PM&R), there is a continued need to focus on diversity among trainees. This study aims to evaluate diversity among PM&R applicants and residents over the past 6 years.ObjectiveTo describe the demographic trends in PM&R over the last 6 years and compare those findings with trends in other specialties.DesignSurveillance.SettingAnalyses of national databases from self‐reported questionnaires.ParticipantsThe study consists of 126,833 medical school matriculants, 374,185 resident applicants, and 326,134 resident trainees over the last 6 years.Main outcome measuresSelf‐reported demographic data from the Association of American Medical Colleges and the Accreditation Council for Graduate Medical Education were analyzed for medical school matriculants, PM&R applicants, and current residents for the cycles of 2014–2015 to 2019–2020. The data were then comparatively reviewed between PM&R and other medical specialties.ResultsIn the 6 cycles evaluated, women accounted for 36%–39% of PM&R residents, but 47%–48% in non‐PM&R specialties. Women applicants to the PM&R specialty averaged 34.4% over the 6 years analyzed, which was the fourth lowest of the 11 specialties examined. Black or African American and Hispanic, Latino, or of Spanish Origin populations each accounted for only 6% of PM&R residents. PM&R demonstrated a noticeably higher proportion of White (62.1% vs. 60.3%) and an observably lower proportion of Black or African American (6.0% vs. 7.1%) and Hispanic, Latino, or of Spanish Origin (6.3% vs. 7.9%) residents compared with non‐PM&R specialties.ConclusionThere is underrepresentation of women and multiple racial and ethnic minority groups in the field of PM&R from applicants to trainees demonstrating a need to improve recruitment efforts.

AbstractObjectiveTo analyze the association between preoperative electrodiagnostic (EDX) studies and postoperative pain and functional outcomes following ulnar nerve decompression and/or transposition for ulnar neuropathy at the elbow (UNE).Literature SurveyProtocol was submitted and database search was conducted by an experienced librarian of all available studies in the English language from 1990 to June 8, 2022. Databases included Ovid MEDLINE(R) and Epub Ahead of Print, In‐Process & Other Non‐Indexed Citations and Daily, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, and Scopus.MethodologyInclusion criteria consisted of randomized controlled trials, prospective and retrospective longitudinal studies, and studies involving adults ≥18 years of age who underwent ulnar nerve decompression and/or transposition for UNE. Study quality and risk of bias were assessed using the National Heart, Lung, and Blood Institute (NHLBI) Study Quality of Assessment Tool. Certainty in evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. A meta‐analysis was not performed.SynthesisA total of 289 studies were screened, and 8 retrospective cohort studies met inclusion criteria comprising 762 patients. A decreased or absent preoperative sensory nerve action potential amplitude (SNAP) showed significance with worse postoperative outcomes. The presence of preoperative conduction block showed significance in higher quality studies. There was limited evidence for slow preoperative motor conduction velocities or preoperative electromyography (EMG) abnormalities and postoperative outcomes. Overall quality assessment demonstrated that two studies had “good,” four “fair,” and two “poor” quality of evidence. Certainty in evidence was “low” due to risk of bias.ConclusionsA decreased or absent preoperative ulnar SNAP may predict worse postoperative outcomes. Per higher quality studies, preoperative conduction block at the elbow may also predict worse postoperative outcomes. Careful interpretation is required with a full understanding of the limited evidence, risk of bias, and low certainty in evidence to support the use of preoperative EDX to predict postoperative outcomes in UNE.
