A Comprehensive Dataset of Histopathology Images, Grades and Patient Demographics for Human Osteoarthritis Cartilage

Abstract Introduction This article compares opioid use patterns following four-corner arthrodesis (FCA) and proximal row carpectomy (PRC) and identifies risk factors and complications associated with prolonged opioid consumption. Materials and Methods The PearlDiver Research Program was used to identify patients undergoing primary FCA (Current Procedural Terminology [CPT] codes 25820, 25825) or PRC (CPT 25215) from 2007 to 2017. Patient demographics, comorbidities, perioperative opioid use, and postoperative complications were assessed. Opioids were identified through generic drug codes while complications were defined by International Classification of Diseases, Ninth and Tenth Revisions, Clinical Modification codes. Multivariable logistic regressions were performed with p < 0.05 considered statistically significant. Results A total of 888 patients underwent FCA and 835 underwent PRC. Three months postoperatively, more FCA patients (18.0%) continued to use opioids than PRC patients (14.7%) (p = 0.033). Preoperative opioid use was the strongest risk factor for prolonged opioid use for both FCA (odds ratio [OR]: 4.91; p < 0.001) and PRC (OR: 6.33; p < 0.001). Prolonged opioid use was associated with an increased risk of implant complications (OR: 4.96; p < 0.001) and conversion to total wrist arthrodesis (OR: 3.55; p < 0.001) following FCA. Conclusion Prolonged postoperative opioid use is more frequent in patients undergoing FCA than PRC. Understanding the prevalence, risk factors, and complications associated with prolonged postoperative opioid use after these procedures may help physicians counsel patients and implement opioid minimization strategies preoperatively.

Background: Stent-assisted coiling is an effective method of treating intracranial aneurysms. The aim of the study was to assess the safety and efficacy of the new Accero stent for the treatment of intracranial aneurysms. Materials and Methods: It was a retrospective, single-center study. Eighteen unruptured intracranial aneurysms were treated using the stent-assisted coiling method with the Accero stent. Patient demographics, aneurysm characteristics, procedural parameters, grade of occlusion, complications, and clinical results were analyzed. Follow-up magnetic resonance (MR) was performed 6 months after intervention. Results: Seventeen patients with 18 incidental unruptured aneurysms were electively treated with coiling and the Accero stent. The aneurysms were located on internal carotid artery (ICA), middle cerebral artery (MCA) and basilar artery (BA). All stents were deployed successfully. Immediate complete occlusion rate Raymond-Roy occlusion classification (RROC) class I was achieved in 13 cases and class II in 4 cases. Complications occurred in 2/17 treatments and included guidewire stent perforation with subarachnoid hemorrhage (SAH) and stent deformation. Vascular spasm in the subarachnoid hemorrhage (SAH) patient subsided before discharge. Ninety days after intervention, the modified Rankin Scale (mRS) value was 0. RROC class I was observed in 88.23% of cases in follow-up. Conclusion: The Accero stent provides excellent support for coil mass. It constitutes an efficacious device with good initial occlusion rate for treating wide-necked unruptured intracranial aneurysms.

Study Results

Introduction: Whole-body computed tomography scans (WBCT) are a mainstay in the work-up of polytrauma or multiple trauma patients in the emergency department. While incredibly useful for identifying traumatic injuries, WBCTs also reveal incidental findings in patients, some of which require further diagnostic testing and subsequent treatment. Although the presence of incidental findings in WBCTs have been well documented, there has been no systematic review conducted to organize and interpret findings, determine IF prevalence, and document strategies for best management. Methods: A systematic review was conducted using MEDLINE, PUBMED, and EMBASE. Specific journals and reference lists were hand-mined, and Google Scholar was used to find any additional papers. Data synthesis was performed to gather information on patient demographics, prevalence and type of incidental findings (IFs), and follow-up management was collected. All documents were independently assessed by the two reviewers for inclusion and any disagreements were resolved by consensus. Results: 1231 study results were identified, 59 abstracts, and 12 included in final review. A mean of 53.9% of patients had at least one IF identified, 31.5% had major findings, and 68.5% had minor findings. A mean of 2.7 IFs per patient was reported for articles that included number of total IFs. The mean age of patients included in the studies were 44 years old with IFs more common in older patients and men with more IFs than women. IFs were most commonly found in the abdominal/pelvic region followed by kidneys. Frequency of follow-up documentation was poor. The most common reported mechanisms of injury for patients included in the study were MVA and road traffic accidents (60.0%) followed by falls from >3m (23.2%). Conclusion: Although there is good documentation on the mechanism of injury, patient demographics, and type of IF, follow-up for IFs following acute trauma admission lacks documentation and follow-up and is an identified issue in patient management. There is great need for systematic protocols to address management of IFs in polytrauma patients.

Abstract Introduction Osteomyelitis refers to an inflammatory process affecting bone and bone marrow. This study reviews chronic femoral osteomyelitis treatment and outcomes, including economic impact. Method We retrospectively collected data from a consecutive series of 14 chronic femoral osteomyelitis patients treated between January 2013 and January 2020. Data collected include patient demographics, comorbidities, pathogens, complications, treatment protocol and costs. Functional outcome was assessed using EuroQOL five-dimensional interview administration questionnaire (EQ-5D-5L™) and EuroQOL Visual Analogue Scale (EQ-VAS™). Results Of these, 92.9% had one or more osteomyelitis risk factor, including smoking and diabetes. Samples from 78.6% grew at least one pathogen. Only 42.9% achieved remission after initial treatment, but 85.7% were in remission at final follow-up, with no signs of recurrence throughout the follow-up period (mean: 21.4 months). The average treatment cost was £39,249.50 with a net mean loss of £19,080.10 when funding was considered. The mean-derived EQ-5D score was 0.360 and the mean EQ-VAS score was 61.7, lower than their values for United Kingdom’s general population, p = 0.0018 and p = 0.013 respectively. Conclusions Chronic femoral osteomyelitis treatment is difficult, resulting in significant economic burden. With previous studies showing cheaper osteomyelitis treatment at specialist centres, our net financial loss incurred suggests the need for management at specialised centres.

AbstractObjectiveVesicular monoamine transporter 2 (VMAT2) inhibitors including valbenazine are first-line therapies for tardive dyskinesia (TD), a persistent movement disorder associated with antipsychotic exposure. This real-world study was performed to assess the association between patient awareness of TD symptoms and clinician-assessed symptom severity.MethodsClinicians who treated antipsychotic-induced TD with a VMAT2 inhibitor within the past 24 months were asked to extract demographic/clinical data from patients charts and complete a survey for additional data, including patient awareness of TD (yes/no) and TD symptom severity (mild/moderate/severe).ResultsData for 601 patients were provided by 163 clinicians (113 psychiatrists; 46 neurologists; 4 primary care physicians). Patient demographics: 50% male; mean age 50.6 years; 55% schizophrenia/schizoaffective disorder; 29% bipolar disorder; 16% other psychiatric diagnoses. Positive relationships were seen between patient awareness and clinician-assessed symptom severity. Awareness was highest in patients with severe symptoms in specific body regions: face (88% vs 78%/69% [awareness by severe vs moderate/mild symptoms]); jaw (90% vs 80%/67%); wrists (90% vs 69%/63%). In other regions, awareness was similar in patients with severe or moderate symptoms: lips (85%/86% vs 68% [severe/moderate vs mild]); tongue (81%/80% vs 73%); neck (80%/78% vs 68%); arms (67%/66% vs 62%); knees (67%/67% vs 53%).ConclusionsIn patients prescribed a VMAT2 inhibitor for TD, patient awareness was generally higher in those determined to have moderate-to-severe symptom severity as assessed by the clinician. More research is needed to understand how awareness and severity contribute to TD burden, and whether different treatment strategies are needed based on these factors.FundingNeurocrine Biosciences, Inc.

Abstract Background To determine real-world outcomes of prostatic urethral lift (UroLift) procedures conducted in hospitals across England. Methods A retrospective observational cohort was identified from Hospital Episode Statistics data including men undergoing UroLift in hospitals in England between 2017 and 2020. Procedure uptake, patient demographics, inpatient complications, 30-day accident and emergency re-attendance rate, requirement for further treatment and catheterization were captured. Kaplan–Meier and hazard analysis were used to analyse time to re-treatment. Results 2942 index UroLift procedures from 80 hospital trusts were analysed; 85.3% conducted as day-case surgery (admitted to hospital for a planned surgical procedure and returning home on the same day). In-hospital complication rate was 3.4%. 93% of men were catheter-free at 30 days. The acute accident and emergency attendance rate within 30 days was 12.0%. Results of Kaplan Meier analysis for subsequent re-treatment (including additional UroLift and endoscopic intervention) at 1 and 2 years were 5.2% [95% CI 4.2 to 6.1] and 11.9% [10.1 to 13.6] respectively. Conclusions This real-world analysis of UroLift shows that it can be delivered safely in a day-case setting with minimal morbidity. However, hospital resource usage for catheterization and emergency hospital attendance in the first 30 days was substantial, and 12% required re-treatment at 2 years.
