RESUMEN
BACKGROUND: Patients who rely on their upper extremities for ambulation, or upper extremity ambulators (UEAs), place considerable stress on their shoulders through the use of assistive devices like walkers, crutches, canes, and wheelchairs. It has been postulated that UEAs may be at increased risk for complications following shoulder arthroplasty. This study aimed to systematically review the literature related to (1) patient-reported outcomes measures (PROMs), (2) functional outcomes, and (3) complications in UEAs who undergo shoulder arthroplasty. METHODS: A systematic review of the PubMed/MEDLINE, Embase, and Cochrane databases was performed to identify studies reporting clinical outcomes of shoulder arthroplasty in UEAs. Patient demographics, clinical characteristics, patient-reported outcomes measures, radiographic outcomes, and postoperative range of motion were collected and compared to control patients (ie bipedal ambulators) from the constituent studies. RESULTS: A total of eight studies evaluating 248 UEA cases and 206 control cases were included for review. Ambulatory assistive devices utilized by UEAs included walkers (39%), wheelchairs (38%), canes (22%), and a crutch (<1%). Among UEA cases, 197 (79%) reverse total shoulder arthroplasty (TSA), 37 (15%) anatomic TSA, and 14 (6%) hemiarthroplasty were performed. Overall, patients exhibited significant improvements in mean American Shoulder and Elbow Surgeons scores, Constant-Murley scores, Simple Shoulder Test scores, and Visual Analog Scale scores postoperatively. Among 3 studies that included comparison with control groups of bipedal ambulators, no significant differences in outcomes were identified. The overall clinical complication rate was 17% for UEAs compared to 9.1% for controls. The rate of revision surgery was 7.7% for UEAs and 4.9% for bipedal ambulators. CONCLUSIONS: UEAs experience satisfactory pain relief, functional improvements, and good subjective outcomes following shoulder arthroplasty. However, complication and revision rates are higher compared to those for bipedal ambulators, and the majority of UEAs undergo reverse shoulder arthroplasty compared to anatomic TSA.
RESUMEN
INTRODUCTION: ChatGPT is an artificial intelligence chatbot software programmed for conversational applications using reinforcement learning techniques. With its growing popularity and overall versatility, it is likely that ChatGPT's applications will expand into health care especially because it relates to patients researching their injuries. The purpose of this study was to investigate ChatGPT's ability to accurately answer frequently asked questions regarding hip fractures. METHODS: Eleven frequently asked questions regarding hip fractures were posed to ChatGPT, and the responses were recorded in full. Five of these questions were determined to be high-yield based on the likelihood that a patient would ask the question to a chatbot software. The chatbot's responses were analyzed by five fellowship-trained orthopaedic trauma surgeons for their quality and accuracy using an evidence-based approach. The chatbot's answers were rated as "Excellent response requiring no clarification", "Satisfactory response requiring minimal clarification", "Satisfactory response requiring moderate clarification", or "Unsatisfactory response requiring significant clarification." RESULTS: Of the five high-yield questions posed to the chatbot, no question was determined to be unsatisfactory requiring significant clarification by the authors. The remaining responses were either satisfactory requiring minimal clarification (n = 3) or satisfactory requiring moderate clarification (n = 2). DISCUSSION: The chatbot was generally found to provide unbiased and evidence-based answers that would be clearly understood by most orthopaedic patients. These findings suggest that ChatGPT has the potential to be an effective patient education tool especially because it continues to grow and improve as a chatbot application. LEVEL OF EVIDENCE: Level IV study.

BACKGROUND: Metacarpal fractures are common and account for over 30% of all hand fractures. Previous literature has shown similar outcomes between operative and nonoperative management of metacarpal shaft fractures. There is little information regarding the natural history of conservatively managed metacarpal shaft fractures and changes in management based on follow-up radiographs. METHODS: A retrospective chart review was performed on all patients who presented to a single institution with an extraarticular metacarpal shaft or base fracture between 2015 and 2019. RESULTS: Thirty-one patients with 37 metacarpal fractures were included for review: average age 41 years, male 48%, right hand dominant 91%, and average follow-up duration 7.3 weeks. At follow-up, a change of 2.4° in angulation (P = .0005) and a change in shortening of 0.1 mm (P = .0386) were noted over the 6-week time interval. No fractures had malrotation at presentation, and none developed malrotation during the follow-up period. CONCLUSIONS: Recent systematic reviews and meta-analysis have suggested that metacarpal fractures treated nonoperatively had similar outcomes to surgical fixation at 12 months of follow-up. We found that extraarticular metacarpal shaft fractures that do not meet operative indications at the initial visit should be expected to heal reliably with minimal change in angulation and shortening over time. The transition to removable brace or no brace at the 2-week follow-up is likely sufficient, and additional follow-up is not necessary and will reduce cost. LEVEL OF EVIDENCE: Level III.
RESUMEN
Importance: Financial incentives for weight management may increase use of evidence-based strategies while addressing obesity-related economic disparities in low-income populations. Objective: To examine the effects of 2 financial incentive strategies developed using behavioral economic theory when added to provision of weight management resources. Design, Setting, and Participants: Three-group, randomized clinical trial conducted from November 2017 to May 2021 at 3 hospital-based clinics in New York City, New York, and Los Angeles, California. A total of 1280 adults with obesity living in low-income neighborhoods were invited to participate, and 668 were enrolled. Interventions: Participants were randomly assigned to goal-directed incentives, outcome-based incentives, or a resources-only group. The resources-only group participants were given a 1-year commercial weight-loss program membership, self-monitoring tools (digital scale, food journal, and physical activity monitor), health education, and monthly one-on-one check-in visits. The goal-directed group included resources and linked financial incentives to evidence-based weight-loss behaviors. The outcome-based arm included resources and linked financial incentives to percentage of weight loss. Participants in the incentive groups could earn up to $750. Main Outcomes and Measures: Proportion of patients achieving 5% or greater weight loss at 6 months. Results: The mean (SD) age of the 668 participants enrolled was 47.7 (12.4) years; 541 (81.0%) were women, 485 (72.6%) were Hispanic, and 99 (14.8%) were Black. The mean (SD) weight at enrollment was 98.96 (20.54) kg, and the mean body mass index (calculated as weight in kilograms divided by height in meters squared) was 37.95 (6.55). At 6 months, the adjusted proportion of patients who lost at least 5% of baseline weight was 22.1% in the resources-only group, 39.0% in the goal-directed group, and 49.1% in the outcome-based incentive group (difference, 10.08 percentage points [95% CI, 1.31-18.85] for outcome based vs goal directed; difference, 27.03 percentage points [95% CI, 18.20-35.86] and 16.95 percentage points [95% CI, 8.18-25.72] for outcome based or goal directed vs resources only, respectively). However, mean percentage of weight loss was similar in the incentive arms. Mean earned incentives was $440.44 in the goal-directed group and $303.56 in the outcome-based group, but incentives did not improve financial well-being. Conclusions and Relevance: In this randomized clinical trial, outcome-based and goal-directed financial incentives were similarly effective, and both strategies were more effective than providing resources only for clinically significant weight loss in low-income populations with obesity. Future studies should evaluate cost-effectiveness and long-term outcomes. Trial Registration: ClinicalTrials.gov Identifier: NCT03157713.

Almost half of patients who meet American College of Cardiology/American Heart Association (ACC/AHA) criteria for statin therapy are untreated. We aimed to evaluate patient-reported reasons for not using guideline-recommended statin therapy in a public healthcare system. Achieving this goal is key to addressing gaps in care and reducing preventable cardiovascular morbidity. We surveyed patients who met 2013 ACC/AHA guidelines for statin therapy but were not using statins. The survey probed domains of patient knowledge regarding cardiovascular health and benefits of statins, barriers to use, physician trust, and interest in cardiovascular care. Among 71 patients eligible for guideline-recommended statin therapy but not currently taking statins, 49 (69%) had a high school education or lower, 41 (58%) reported that they were unaware they should be prescribed a statin and 49 (69%) were unaware of the benefits of statins. Almost all patients, 70 (99%), reported caring about their cardiovascular health, 61 (86%) reported that they had a high level of trust in their physician, and 51 (72%) reported a willingness to follow their physician's advice. Despite interest in cardiovascular health, awareness of benefits of statin therapy was low and knowledge of recommended statin therapy was low. Increasing patients' awareness of their eligibility through systematic testing and linkage to statin therapy, along with education, may increase statin use among patients recommended for therapy.
RESUMEN
The causative agent of cholera, Vibrio cholerae, is a public health concern. Multidrug-resistant V. cholerae variants may reduce chemotherapeutic efficacies of severe cholera. We previously reported that the multidrug efflux pump EmrD-3 from V. cholerae confers resistance to multiple structurally distinct antimicrobials. Medicinal plant compounds are potential candidates for EmrD-3 efflux pump modulation. The antibacterial activities of garlic Allium sativum, although poorly understood, predicts that a main bioactive component, allyl sulfide, modulates EmrD-3 efflux. Thus, we tested whether A. sativum extract acts in synergy with antimicrobials and that a main bioactive component allyl sulfide inhibits EmrD-3 efflux. We found that A. sativum extract and allyl sulfide inhibited ethidium bromide efflux in cells harboring EmrD-3 and that A. sativum lowered the MICs of multiple antibacterials. We conclude that A. sativum and allyl sulfide inhibit EmrD-3 and that A. sativum extract synergistically enhances antibacterial agents.
