RESUMO
PURPOSE: To determine whether the free online artificial intelligence platform ChatGPT could accurately, adequately, and appropriately answer questions regarding anterior cruciate ligament (ACL) reconstruction surgery. METHODS: A list of 10 questions about ACL surgery was created based on a review of frequently asked questions that appeared on websites of various orthopaedic institutions. Each question was separately entered into ChatGPT (version 3.5), and responses were recorded, scored, and graded independently by 3 authors. The reading level of the ChatGPT response was calculated using the WordCalc software package, and readability was assessed using the Flesch-Kincaid grade level, Simple Measure of Gobbledygook index, Coleman-Liau index, Gunning fog index, and automated readability index. RESULTS: Of the 10 frequently asked questions entered into ChatGPT, 6 were deemed as unsatisfactory and requiring substantial clarification; 1, as adequate and requiring moderate clarification; 1, as adequate and requiring minor clarification; and 2, as satisfactory and requiring minimal clarification. The mean DISCERN score was 41 (inter-rater reliability, 0.721), indicating the responses to the questions were average. According to the readability assessments, a full understanding of the ChatGPT responses required 13.4 years of education, which corresponds to the reading level of a college sophomore. CONCLUSIONS: Most of the ChatGPT-generated responses were outdated and failed to provide an adequate foundation for patients' understanding regarding their injury and treatment options. The reading level required to understand the responses was too advanced for some patients, leading to potential misunderstanding and misinterpretation of information. ChatGPT lacks the ability to differentiate and prioritize information that is presented to patients. CLINICAL RELEVANCE: Recognizing the shortcomings in artificial intelligence platforms may equip surgeons to better set expectations and provide support for patients considering and preparing for ACL reconstruction.

The public health emergency for coronavirus disease 2019 ended on April 11, 2023, 1 month earlier than its planned termination. The hasty cessation of emergency measures may negatively impact the care of solid organ transplant recipients and other immunosuppressed hosts. Accelerated pathways for drug and vaccine approvals, research funding, and insurance coverage for medical therapies and diagnostic testing are likely to be affected. Health care disparities that characterized the early pandemic may again be intensified. It is imperative that the transplant community promptly anticipate the impact of these changes and prepare accordingly to avoid disruptions in care for the most vulnerable patients.

Human respiratory syncytial virus (RSV) is a negative sense single-stranded RNA virus that can result in epidemics of seasonal respiratory infections. Generally, one of the two genotypes (A and B) predominates in a single season and alternate annually with regional variation. RSV is a known cause of disease and death at both extremes of ages in the pediatric and elderly, as well as immunocompromised populations. The clinical impact of RSV on the hospitalized adults has been recently clarified with the expanded use of multiplex molecular assays. Among adults, RSV can produce a wide range of clinical symptoms due to upper respiratory tract infections potentially leading to severe lower respiratory tract infections, as well as exacerbations of underlying cardiac and lung diseases. While supportive care is the mainstay of therapy, there are currently multiple therapeutic and preventative options under development.

Invasive aspergillosis (IA) is an increasingly recognised phenomenon in critically ill patients in the intensive care unit, including in patients with severe influenza and severe coronavirus disease 2019 (COVID-19) infection. To date, there are no consensus criteria on how to define IA in the ICU population, although several criteria are used, including the AspICU criteria and new consensus criteria to categorise COVID-19-associated pulmonary aspergillosis (CAPA). In this review, we describe the epidemiology of IA in critically ill patients, most common definitions used to define IA in this population, and most common clinical specimens obtained for establishing a mycological diagnosis of IA in the critically ill. We also review the most common diagnostic tests used to diagnose IA in this population, and lastly discuss the most common clinical presentation and imaging findings of IA in the critically ill and discuss areas of further needed investigation.

Three-dimensional transthoracic echocardiography (3DE)-derived heart models have not previously been utilized to guide catheter ablation. In this case report, we describe the creation of a 3DE model from transthoracic echocardiography, import of the model into CARTO3, and successful use of the model as a guide during mapping and ablation of a right lateral accessory pathway. We believe this technique represents a valuable alternative to the integration of computed tomography or magnetic resonance imaging-derived anatomic data, and that it has the potential to improve the definition of the atrioventricular valve annuli during catheter ablation of accessory pathways.

BACKGROUND: Pulmonary insufficiency is a consequence of transannular patch repair in Tetralogy of Fallot (ToF) leading to late morbidity and mortality. Transcatheter native outflow tract pulmonary valve replacement has become a reality. However, predicting a secure, atraumatic implantation of a catheter-based device remains a significant challenge due to the complex and dynamic nature of the right ventricular outflow tract (RVOT). We sought to quantify the differences in compression and volume for actual implants, and those predicted by pre-implant modeling. METHODS: We used custom software to interactively place virtual transcatheter pulmonary valves (TPVs) into RVOT models created from pre-implant and post Harmony valve implant CT scans of 5 ovine surgical models of TOF to quantify and visualize device volume and compression. RESULTS: Virtual device placement visually mimicked actual device placement and allowed for quantification of device volume and radius. On average, simulated proximal and distal device volumes and compression did not vary statistically throughout the cardiac cycle (P = 0.11) but assessment was limited by small sample size. In comparison to actual implants, there was no significant pairwise difference in the proximal third of the device (P > 0.80), but the simulated distal device volume was significantly underestimated relative to actual device implant volume (P = 0.06). CONCLUSIONS: This study demonstrates that pre-implant modeling which assumes a rigid vessel wall may not accurately predict the degree of distal RVOT expansion following actual device placement. We suggest the potential for virtual modeling of TPVR to be a useful adjunct to procedural planning, but further development is needed.

PURPOSE OF REVIEW: Respiratory viruses are common in solid organ transplant (SOT) recipients and recognized as a significant cause of mortality and morbidity. This review examines the literature on influenza and noninfluenza viruses in the SOT recipient. RECENT FINDINGS: Advances in immunosuppression and antimicrobial prophylaxis have led to improved patient and graft survival, yet respiratory viruses continue to be a common cause of disease in this population. Influenza viruses have received top priority regarding prevention and treatment, whereas advances in molecular diagnostic tests detecting an array of other respiratory viruses have expanded our knowledge about the epidemiology and impact of these viruses in both the general population and SOT patients. Effective treatment and prevention for noninfluenza respiratory viruses are only emerging. SUMMARY: Respiratory viruses can contribute to a wide array of symptoms in SOT, particularly in lung transplant recipients. The clinical manifestations, diagnosis, and treatment options for influenza and noninfluenza viruses in SOT patients are reviewed. PCR and related molecular techniques represent the most sensitive diagnostic modalities for detection of respiratory viruses. Early therapy is associated with improved outcomes. Newer classes of antivirals and antibodies are under continuous development for many of these community acquired respiratory viruses.

BACKGROUND: Respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and parainfluenza virus (PIV) hospitalize many people yearly. Though severe lower respiratory tract disease has been described in children, the elderly, and the immunocompromised, there is a gap in our understanding of RSV, hMPV, and PIV in hospitalized adults. We sought to evaluate the association of RSV, hMPV, and PIV with severe respiratory disease requiring noninvasive or mechanical ventilation and death in hospitalized adults in the United States. METHODS: We conducted a retrospective, pooled, cross-sectional study of general medicine hospitalizations in the United States from 2016 to 2019 using the National Inpatient Sample published by the Agency for Healthcare Quality and Research. We used multivariable Poisson regression to estimate the likelihood of severe respiratory disease or death. We used linear regression to estimate the mean difference in length of stay for those hospitalized with and without a respiratory virus. RESULTS: We found that RSV (incidence rate ratio [IRR]: 1.68, 95% confidence interval [CI]: 1.61-1.74, p < .001), hMPV (IRR: 1.82, 95% CI: 1.71-1.93, p < .001), and PIV (IRR: 1.81, 95% CI: 1.68-1.94, p < .001) were independently associated with severe respiratory disease, even after adjustment. Additionally, we found the presence of a respiratory virus prolonged hospitalizations by (0.79 ± 0.27 days, p < .003) for RSV, (0.88 ± 0.28 days, p < .002) for hMPV, and (1.43 ± 0.30 days, p < .001) for PIV. CONCLUSIONS: RSV, hMPV, and PIV have a significant burden on hospitalized adults, even without classic risk factors.

BACKGROUND: The Food and Drug Administration (FDA) maintains the Manufacturer and User Facility Device Experience (MAUDE) database for reporting adverse events associated with medical devices, including emerging technologies, such as robotic-assisted total hip arthroplasty (THA). Aim of this study was to evaluate the variation of adverse events associated with robotics in THA. METHODS: Medical device reports (MDRs) within the MAUDE database were identified between 2017 and 2021. For MDR identification the product class "orthopaedic stereotaxic equipment" and terms associated with THA were used. Individual adverse events were identified and organised by type and consequences, such as patient injury, surgical delay, or conversion to the manual technique. RESULTS: 521 MDRs constituting 546 discrete events were found. The most common reported complication was intraoperative hardware failure (304/546, 55.7%), among which the most common failure was a broken impaction handle/platform (110, 20.1%). Inaccurate cup placement was the second most common reported complication (63, 11.5%). Abandoning the robot occurred in 13.0% (71/521) of reports. A surgical delay was noted in 28% (146/521) of reports, with an average delay of 17.9 (range 1-60) minutes. CONCLUSIONS: Identifying complications that may occur with robotics in THA is an important first step in preventing adverse events and surgical delays. Database analysis provide an overview of the range of complications.
RESUMO
Patients undergoing allogenic hematopoietic stem cell transplantation (HSCT) are at an increased risk of mortality due to transplantation-related complications in the first year post-transplantation, owing in part to the profound immune dysregulation with T cell and B cell lymphopenia and functional impairment. Although several large studies have reported higher mortality rates from Coronavirus disease 2019 (COVID-19) in HSCT recipients, to date no study has focused on the impact of early COVID-19 infection on immune reconstitution post-transplantation and the correlation with transplantation outcomes. We retrospectively analyzed 61 consecutive adult patients who underwent their first allogeneic HSCT at our institution. Thirteen patients (21.3%) experienced early COVID-19 infection, with a median time to diagnosis of 100 days post-transplantation. In multivariable analysis, patients with early COVID-19 infection had significantly worse overall survival (adjusted hazard ratio [aHR], 4.06; 95% confidence interval [CI], 1.26 to 13.05; P = .019) and progression-free survival (aHR, 6.68; 95% CI, 2.11 to 21.11; P = .001). This was attributed mainly to higher nonrelapse mortality (NRM) among early COVID-19 patients (P = .042). Allogeneic HSCT recipients with early COVID-19 infection had significant delays in absolute lymphocyte count (95% CI, -703.69 to -56.79; P = .021), CD3+CD4+ cell (95% CI, -105.35 to -11.59; P = .042), CD3+CD8+ cell (95% CI, -324.55 to -57.13; P = .038), and CD3-CD56+ cell (95% CI, -193.51 to -47.31; P = .014) recovery compared to those without early COVID-19 infection. Our findings suggest that patients with early COVID-19 infection after allogeneic HSCT have higher NRM and worse survival, at least in part due to impaired immune reconstitution post-transplantation.

BACKGROUND: The incidence of phantom limb pain in patients with Charcot neuroarthropathy who undergo major amputation is not well described. The purpose of this study was to determine whether patients with Charcot neuroarthropathy and diabetes who underwent either a below-knee amputation (BKA) or above-knee amputation (AKA) had an increased rate of phantom limb pain compared with those with a diagnosis of diabetes alone. METHODS: Using international classification of disease (ICD) and common procedural terminology (CPT) codes, the TriNetX research database identified 10 239 patients who underwent BKA and 6122 who underwent AKA between 2012 and 2022. Diabetic patients with and without Charcot neuroarthropathy were compared in terms of demographics and relative risk of developing phantom limb pain after AKA or BKA. RESULTS: Age, sex, ethnicity, and race did not significantly differ between groups. Charcot neuroarthropathy was associated with significantly increased risk of phantom limb pain following both BKA (risk ratio [RR]: 1.2, 95% confidence interval [CI]: 1.1-1.3, P < .01) and AKA (RR: 1.6, 95% CI: 1.2-2.3, P < .0068). CONCLUSION: Our results indicate that patients with a coexisting diagnosis of Charcot neuroarthropathy who require BKA or AKA may have an increased risk of developing phantom limb pain. LEVELS OF EVIDENCE: Level III.
RESUMO
Respiratory Syncytial Virus (RSV) is a leading cause of acute respiratory tract infection, with the greatest impact on infants, immunocompromised individuals, and older adults. RSV prevalence decreased substantially in the United States (US) following the implementation of COVID-19-related non-pharmaceutical interventions but later rebounded with abnormal seasonality. The biological and epidemiological factors underlying this altered behavior remain poorly defined. In this retrospective cohort study from 2009 to 2023 in Chicago, Illinois, US, we examined RSV epidemiology, clinical severity, and genetic diversity. We found that changes in RSV diagnostic platforms drove increased detections in outpatient settings post-2020 and that hospitalized adults infected with RSV-A were at higher risk of intensive care admission than those with RSV-B. While population structures of RSV-A remained unchanged, RSV-B exhibited a genetic shift into geographically distinct clusters. Mutations in the antigenic regions of the fusion protein suggest convergent evolution with potential implications for vaccine and therapeutic development.

Prosthetic joint infection (PJI) is a costly and potentially fatal complication in total ankle arthroplasty (TAA). Some surgeons apply topical vancomycin powder to minimize the risk of infection during TAA procedures. The purpose of our study was to determine the cost-effectiveness of using vancomycin powder to prevent PJI following TAA and to propose an economic model that can be applied by foot and ankle surgeons in their decision to incorporate vancomycin powder in practice. Using our institution's records of the cost of 1 g of topical vancomycin powder, we performed a break-even analysis and calculated the absolute risk reduction and number needed to treat for varying costs of vancomycin powder, PJI infection rates, and costs of TAA revision. Costing $3.06 per gram at our institution, vancomycin powder was determined to be cost-effective in TAA if the PJI rate of 3% decreased by an absolute risk reduction of 0.02% (Number Needed to Treat = 5304). Furthermore, our results indicate that vancomycin powder can be highly cost-effective across a wide range of costs, PJI infection rates, and varying costs of TAA revision. The use of vancomycin powder remained cost-effective even when (1) the price of vancomycin powder was as low as $2.50 to as high as $100.00, (2) infection rates ranged from .05 to 3%, and (3) the cost of the TAA revision procedure ranged from $1000 to $10 000.Levels of Evidence: IV.

Background: Previous research suggests that estrogen plays a role in increased ligamentous laxity observed within the female population. Whereas many studies have sought to evaluate the impact of exogenous estrogen on anterior cruciate ligament injuries, research has not yet explored its impact on the medial patellofemoral ligament. Furthermore, less is known about the role of exogenous progesterone on ligamentous structures. Purpose: To determine whether women prescribed systemic estrogen (ethinyl estradiol) or progesterone (norgestimate or etonogestrel) hormonal contraceptives had an increased risk of undergoing reconstruction surgery for patellar instability compared with women without a prescription for systemic hormonal contraceptives. Study Design: Cross-sectional study; Level of evidence, 3. Methods: The TriNetX Research Network database was queried using International Classification of Disease and Common Procedural Terminology codes for women aged 15 to 26 years who underwent reconstruction procedures for patellar instability between 2012 and 2022. Women were grouped according to whether they had a coded prescription for a systemic hormonal contraceptive containing either ethinyl estradiol or etonogestrel; controls were matched by age, sex, race, and ethnicity. The relative risk (RR) of undergoing reconstruction for patellar instability was determined for each contraceptive. Results: After 1-to-1 propensity score matching, 0.054% (525/980,878) of women prescribed a systemic contraceptive containing ethinyl estradiol underwent reconstruction procedures for patellar instability compared with 0.043% (417/980,878) of controls (RR, 1.3; 95% CI, 1.1-1.4; P = .0004). Likewise, 0.058% (67/116,260) of women prescribed a form of systemic contraceptive containing only etonogestrel underwent reconstruction procedures for patellar instability compared with 0.026% (30/116,260) of controls (RR, 2.2; 95% CI, 1.5-3.4; P = .0002). Conclusion: Female patients prescribed systemic contraceptives containing estrogen or progesterone had an increased rate of reconstruction procedures for patellar instability.
RESUMO
BACKGROUND: The representation of sociodemographic data within randomized-controlled trials (RCT) regarding foot and ankle surgery is undefined. The purpose of this study was to determine the incidence of sociodemographic data being reported in contemporary foot and ankle RCTs. METHODS: Randomized-controlled trials within the PubMed database from 2016 to 2021 were searched and the full text of 40 articles was reviewed to identify sociodemographic variables reported in the manuscript. Data regarding race, ethnicity, insurance status, income, work status, and education were collected. RESULTS: Race was reported in the results in 4 studies (10.0%), ethnicity in 1 (2.5%), insurance status in 0 (0%), income in 1 (2.5%), work status in 3 (7.5%) and education in 2 (5.0%). In any section other than the results, race was reported in 6 studies (15.0%), ethnicity in 1 (2.5%), insurance status in 3 (7.5%), income in 6 (15.0%), work status in 6 (15.0%), and education in 3 (7.5%). There was no difference in sociodemographic data by journal (P = .212), year of publication (P = .216), or outcome study (P = .604). CONCLUSION: The overall rate of sociodemographic data reported in foot and ankle RCTs is low. There was no difference in the reporting of sociodemographic data between journal, year of publication, or outcome study. LEVEL OF EVIDENCE: Level II.
RESUMO
BACKGROUND: In hypoplastic left heart syndrome, tricuspid regurgitation (TR) is associated with circulatory failure and death. We hypothesized that the tricuspid valve (TV) structure of patients with hypoplastic left heart syndrome with a Fontan circulation and moderate or greater TR differs from those with mild or less TR, and that right ventricle volume is associated with TV structure and dysfunction. METHODS: TV of 100 patients with hypoplastic left heart syndrome and a Fontan circulation were modeled using transthoracic 3-dimensional echocardiograms and custom software in SlicerHeart. Associations of TV structure to TR grade and right ventricle function and volume were investigated. Shape parameterization and analysis was used to calculate the mean shape of the TV leaflets, their principal modes of variation, and to characterize associations of TV leaflet shape to TR. RESULTS: In univariate modeling, patients with moderate or greater TR had larger TV annular diameters and area, greater annular distance between the anteroseptal commissure and anteroposterior commissure, greater leaflet billow volume, and more laterally directed anterior papillary muscle angles compared to valves with mild or less TR (all P<0.001). In multivariate modeling greater total billow volume, lower anterior papillary muscle angle, and greater distance between the anteroposterior commissure and anteroseptal commissure were associated with moderate or greater TR (P<0.001, C statistic=0.85). Larger right ventricle volumes were associated with moderate or greater TR (P<0.001). TV shape analysis revealed structural features associated with TR, but also highly heterogeneous TV leaflet structure. CONCLUSIONS: Moderate or greater TR in patients with hypoplastic left heart syndrome with a Fontan circulation is associated with greater leaflet billow volume, a more laterally directed anterior papillary muscle angle, and greater annular distance between the anteroseptal commissure and anteroposterior commissure. However, there is significant heterogeneity of structure in the TV leaflets in regurgitant valves. Given this variability, an image-informed patient-specific approach to surgical planning may be needed to achieve optimal outcomes in this vulnerable and challenging population.

BACKGROUND: Acute invasive fungal sinusitis (AIFS) is an aggressive disease that requires prompt diagnosis and multidisciplinary treatment given its rapid progression. However, there is currently no consensus on diagnosis, prognosis, and management strategies for AIFS, with multiple modalities routinely employed. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on AIFS, summarize the existing evidence, and provide recommendations on the management of AIFS. METHODS: The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through January 2022. Studies evaluating management for orbital, non-sinonasal head and neck, and intracranial manifestations of AIFS were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on management principles for AIFS were generated. RESULTS: A review and evaluation of published literature was performed on 12 topics surrounding AIFS (signs and symptoms, laboratory and microbiology diagnostics, endoscopy, imaging, pathology, surgery, medical therapy, management of extrasinus extension, reversing immunosuppression, and outcomes and survival). The aggregate quality of evidence was varied across reviewed domains. CONCLUSION: Based on the currently available evidence, judicious utilization of a combination of history and physical examination, laboratory and histopathologic techniques, and endoscopy provide the cornerstone for accurate diagnosis of AIFS. In addition, AIFS is optimally managed by a multidisciplinary team via a combination of surgery (including resection whenever possible), antifungal therapy, and correcting sources of immunosuppression. Higher quality (i.e., prospective) studies are needed to better define the roles of each modality and determine diagnosis and treatment algorithms.

Infection is a leading cause of morbidity and mortality in patients with ventricular assist devices (VAD). The impact of colonization with multidrug-resistant organisms (MDRO) on outcomes in this cohort is unknown. Patients on VAD support from July 2008 to September 2018 at a single site were evaluated for MDRO colonization after implantation. MDROs included methicillin-resistant Staphylococcus aureus , vancomycin-resistant Enterococcus species, and extended-spectrum beta-lactamase producing gram-negative bacteria. 378 patients with 433 VADs were included. 42.6% (n = 161) of patients were colonized with an MDRO throughout the duration of VAD support. Eighty-two VAD infections occurred, 74.4% (n = 61) of whom were MDRO colonized before infection. MDRO colonization was associated with an increased risk of a subsequent VAD infection (hazard ratio 3.704, p < 0.001). MDRO colonization is common after VAD implantation and is associated with future VAD infections. Further study is needed to determine best management strategies for VAD recipients with MDRO colonization given this increased risk.

Hypoplastic left heart syndrome (HLHS) is a congenital heart disease characterized by incomplete development of the left heart. Children with HLHS undergo a series of operations which result in the tricuspid valve (TV) becoming the only functional atrioventricular valve. Some of those patients develop tricuspid regurgitation which is associated with heart failure and death and necessitates further surgical intervention. Repair of the regurgitant TV, and understanding the connections between structure and function of this valve remains extremely challenging. Adult cardiac populations have used 3D echocardiography (3DE) combined with computational modeling to better understand cardiac conditions affecting the TV. However, these structure-function analyses rely on simplistic point-based techniques that do not capture the leaflet surface in detail, nor do they allow robust comparison of shapes across groups. We propose using statistical shape modeling and analysis of the TV using Spherical Harmonic Representation Point Distribution Models (SPHARM-PDM) in order to generate a reproducible representation, which in turn enables high dimensional low sample size statistical analysis techniques such as principal component analysis and distance weighted discrimination. Our initial results suggest that visualization of the differences in regurgitant vs. non-regurgitant valves can precisely locate populational structural differences as well as how an individual regurgitant valve differs from the mean shape of functional valves. We believe that these results will support the creation of modern image-based modeling tools, and ultimately increase the understanding of the relationship between valve structure and function needed to inform and improve surgical planning in HLHS.
