RESUMO

BACKGROUND: Marrow stimulation is a common reparative approach to treat injuries to cartilage and other soft tissues (e.g., rotator cuff). It involves the recruitment of bone marrow elements and mesenchymal stem cells (MSCs) into the defect, theoretically initiating a regenerative process. However, the resulting repair tissue is often weak and susceptible to deterioration with time. The populations of cells at the marrow stimulation site (beyond MSCs), and their contribution to inflammation, vascularity, and fibrosis, may play a role in quality of the repair tissue. SUMMARY: In this review, we accomplish three goals: 1) systematically review clinical trials on the augmentation of marrow stimulation and evaluate their assumptions on the biological elements recruited; 2) detail the cellular populations in bone marrow and their impact on healing; and 3) highlight emerging technologies and approaches that could better guide these specific cell populations towards enhanced cartilage or soft tissue formation. KEY MESSAGES: We found that most clinical trials do not account for cell heterogeneity, nor do they specify the regenerative element recruited, and those that do typically utilize descriptions such as "clots", "elements", and "blood". Furthermore, our review of bone marrow cell populations demonstrates a dramatically heterogenous cell population, including hematopoietic cells, immune cells, fibroblasts, macrophages, and only a small population of MSCs. Finally, the field has developed numerous innovative techniques to enhance the chondrogenic potential (and reduce the anti-regenerative impacts) of these various cell types. We hope this review will guide approaches that account for cellular heterogeneity and improve marrow stimulation techniques to treat chondral defects.

RESUMO

RESEARCH QUESTION: Do embryos that undergo a thaw, biopsy and re-vitrification (TBR) for pre-implantation genetic testing for aneuploidy (PGT-A) have different ploidy and transfer outcomes compared with fresh biopsied embryos? DESIGN: Retrospective cohort study of all embryos that underwent the following procedures: fresh biopsy for PGT-A (fresh biopsy); embryos that were warmed, biopsied for PGT-A and re-vitrified (single biopsy TBR); embryos with a no signal result after initial biopsy that were subsequently warmed, biopsied and re-vitrified (double biopsy TBR). The patients who underwent transfers of those embryos at a single academic institution between March 2013 and December 2021 were also studied. RESULTS: About 30% of embryos planned for TBR underwent attrition. Euploidy rates were similar after biopsy: fresh biopsy (42.7%); single biopsy TBR (47.5%) (adjusted RR: 0.99, 0.88 to 1.12); and double biopsy TBR 50.3% (adjusted RR: 0.99, 0.80 to 1.21). Ongoing pregnancy over 8 weeks was not statistically significant (double biopsy TBR: 6/19 [31.6%] versus fresh biopsy: 650/1062 [61.2%]) (adjusted RR 0.52, 95% CI 0.26 to 1.03). The miscarriage rate increased (double biopsy TBR: 4/19 [21.1%] versus fresh biopsy: 66/1062 [6.2%])(RR 3.39, 95% CI 1.38 to 8.31). Live birth rate was also lower per transfer for the double biopsy TBR group (double biopsy TBR [18.75%] versus fresh biopsy [53.75%]) (RR 0.35, 95% CI 0.12 to 0.98), though not after adjustment (adjusted RR 0.37, 95% CI 0.13 to 1.09). These differences were not seen when single biopsy TBR embryos were transferred. CONCLUSIONS: Embryos that undergo TBR have an equivalent euploidy rate to fresh biopsied embryos. Despite that, double biopsy TBR embryos may have impaired transfer outcomes.

RESUMO

BACKGROUND: Comprehensive geriatric assessment (CGA) involves a formal broad approach to assess frailty and creating a plan for management. However, the impact of CGA and its components on listing for kidney transplant in older adults has not been investigated. METHODS: We performed a single-center retrospective study of patients with end-stage renal disease who underwent CGA during kidney transplant candidacy evaluation between 2017 and 2021. All patients ≥ 65 years old and those under 65 with any team member concern for frailty were referred for CGA, which included measurements of healthcare utilization, comorbidities, social support, short physical performance battery, Montreal Cognitive Assessment (MoCA), and Physical Frailty Phenotype (FPP), and estimate of surgical risk by the geriatrician. RESULTS: Two hundred and thirty patients underwent baseline CGA evaluation; 58.7% (135) had high CGA ("Excellent" or "Good" rating for transplant candidacy) and 41.3% (95) had low CGA ratings ("Borderline," "Fair," or "Poor"). High CGA rating (OR 8.46; p < 0.05), greater number of CGA visits (OR 4.93; p = 0.05), younger age (OR 0.88; p < 0.05), higher MoCA scores (OR 1.17; p < 0.05), and high physical activity (OR 4.41; p < 0.05) were all associated with listing on transplant waitlist. CONCLUSIONS: The CGA is a useful, comprehensive tool to help select older adults for kidney transplantation. Further study is needed to better understand the predictive value of CGA in predicting post-operative outcomes.

RESUMO

Despite advancing treatment methods, esophageal cancer (EC) maintains a high mortality rate and poor prognosis. Through various mechanisms, aspirin has been suggested to have a chemopreventive effect on EC. However, the long-term impact, particularly regarding the rate of metastasis, needs to be further elucidated. NIS 2016-2020 was used to identify adult patients (age > 18 years) with EC using ICD-10 codes. Patients with missing demographics and mortality were excluded. Patients were stratified into two groups based on aspirin use. Data were collected on patient demographics, Elixhauser Comorbidity Index (ECI), and comorbidities (hypertension, chronic pulmonary disease, coronary artery disease (CAD), chronic kidney disease (CKD), congestive heart failure (CHF), coagulopathy, alcohol use, smoking, and obesity). The outcomes studied were rates of total metastasis, gastrointestinal (GI) metastasis, non-GI metastasis, and lymphoid metastasis. Multivariate logistic regression analysis was performed to evaluate the impact of aspirin use on various metastases after adjusting for patient demographics, comorbidities, and ECI. Out of 190,655 patients, 20,650 (10.8%) patients were aspirin users. Majority of the patients in the aspirin group were aged > 65 years (74.7%), males (82.1%), White race (84%), and had medicare insurance (71%). There was a higher incidence of diabetes, hypertension, chronic pulmonary disease, CAD, CKD, CHF, and smoking in aspirin users than non-aspirin users. Patients with aspirin users had a lower incidence of metastasis (28.9% vs. 38.7%, P < 0.001), GI metastasis (14.2% vs. 20.6%, P < 0.001), non-GI metastasis (15.1% vs. 22%, P < 0.001), and lymphoid metastasis (8.9% vs. 11.3%, P < 0.001) than non-aspirin users. After adjusting for confounding factors, patients with aspirin use had lower odds of having metastasis (aOR-0.73, 95% CI-0.70-0.77, P < 0.001). Our study noted that aspirin use is associated with a reduction in the rate of metastasis in patients with EC. These studies support the use of aspirin in patients with EC and suggest the need for further studies to understand the mechanism by which aspirin use reduces metastasis in patients with EC.

RESUMO

BACKGROUND: Although prior research has estimated the overarching cost burden of heart failure (HF), a thorough analysis examining medical expense differences and trends, specifically among commercially insured patients with heart failure, is still lacking. Thus, the study aims to examine historical trends and differences in medical costs for commercially insured heart failure patients in the United States from 2006 to 2021. METHODS: A population-based, cross-sectional analysis of medical and pharmacy claims data (IQVIA PharMetrics® Plus for Academic) from 2006 to 2021 was conducted. The cohort included adult patients (age > = 18) who were enrolled in commercial insurance plans and had healthcare encounters with a primary diagnosis of HF. The primary outcome measures were the average total annual payment per patient and per cost categories encompassing hospitalization, surgery, emergency department (ED) visits, outpatient care, post-discharge care, and medications. The sub-group measures included systolic, diastolic, and systolic combined with diastolic, age, gender, comorbidity, regions, states, insurance payment, and self-payment. RESULTS: The study included 422,289 commercially insured heart failure (HF) patients in the U.S. evaluated from 2006 to 2021. The average total annual cost per patient decreased overall from $9,636.99 to $8,201.89, with an average annual percentage change (AAPC) of -1.11% (95% CI: -2% to -0.26%). Hospitalization and medication costs decreased with an AAPC of -1.99% (95% CI: -3.25% to -0.8%) and - 3.1% (95% CI: -6.86-0.69%). On the other hand, post-discharge, outpatient, ED visit, and surgery costs increased by an AAPC of 0.84% (95% CI: 0.12-1.49%), 4.31% (95% CI: 1.03-7.63%), 7.21% (95% CI: 6.44-8.12%), and 9.36% (95% CI: 8.61-10.19%). CONCLUSIONS: The study's findings reveal a rising trend in average total annual payments per patient from 2006 to 2015, followed by a subsequent decrease from 2016 to 2021. This decrease was attributed to the decline in average patient costs within the Medicare Cost insurance category after 2016, coinciding with the implementation of the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015. Additionally, expenses related to surgical procedures, emergency department (ED) visits, and outpatient care have shown substantial growth over time. Moreover, significant differences across various variables have been identified.

RESUMO

OBJECTIVES: The first case report describing a pediatric fracture of the tibial tubercle was published in 1852 in the Medical Times and Gazette, a Journal of Medical Science, literature, criticism, and news. A century later, in 1955, Sir Watson-Jones introduced the first classification system for this fracture. Despite the existence of several classification systems for pediatric tibial tubercle fractures in the medical literature, a crucial aspect of their validation-reliability and reproducibility-has not yet been systematically evaluated. METHODS: In this study, a modified Watson-Jones (mWJ) classification system of tibial tubercle fractures in children was assessed for intraobserver and interobserver variability. Using the mWJ classification, 3 board-certified pediatric orthopaedic surgeons and 3 orthopaedic surgery residents, classified thirty tibial tubercle fractures based on anteroposterior and lateral radiographs on 2 separate occasions in a 2-week duration. Further comparison was made to evaluate the impact of advanced imaging, specifically computed tomography or magnetic resonance imaging, on diagnostic reliability and reproducibility. RESULTS: The study found substantial intraobserver reliability of the mWJ classification based on radiographs alone, with a Cohen weighted kappa (κ w ) coefficient of 0.733. When advanced imaging was utilized, the reliability of the classification improved to κ w = 0.783. Similarly, interobserver reliability demonstrated substantial consistency among observers when using radiographs alone (κ w = 0.69) and improved agreement with advanced imaging (κ w = 0.75). Notably, there was no significant difference in reliability scores between senior-level attendings and residents when analyzed as separate groups. CONCLUSION: Fracture classification systems are clinically relevant tools that help organize and transfer knowledge efficiently, provide treatment guidance, propose prognostic expectations, and improve communication in academic literature. The present study demonstrated substantial reproducibility of an mWJ fracture classification system both between and within individual surgeon raters. LEVEL OF EVIDENCE: Level III-diagnostic.

RESUMO

BACKGROUND: Symptoms of depression have been associated with greater incapability following total hip arthroplasty (THA). A brief, 2-question, measure of symptoms of depression - the Patient Health Questionnaire-2 (PHQ-2) - may be sufficient to measure associations with the magnitude of incapability during recovery from THA. This study investigated whether preoperative symptoms of depression (measured with the PHQ-2) correlated with levels of incapability 6 weeks and 6 months after THA, accounting for demographic and clinical factors. METHODS: We performed a prospective cohort study across 5 centers and recruited 101 patients undergoing THA, of whom 90 (89%) completed follow-up. Patients completed demographics, a preoperative 2-item (PHQ-2) measure of symptoms of depression, and the Hip Dysfunction and Osteoarthritis Outcome Score for Joint Replacement (HOOS JR) at 6-weeks and 6-months postoperatively. Negative binomial regression models determined factors associated with HOOS JR at 6 weeks and 6 months, accounting for potential confounders. RESULTS: Accounting for potential confounding factors, we found that higher preoperative PHQ-2 scores (reflecting greater symptoms of depression) were associated with lower HOOS JR scores (reflecting a greater level of hip disability) at both 6 weeks (regression coefficient = -0.67, P < .001) and 6 months (regression coefficient = -1.9, P < .001) after THA. CONCLUSIONS: Symptoms of depression on a 2-question preoperative questionnaire are common, and greater symptoms of depression are associated with reduced capability within the first year following THA. These findings support the prioritization of routine mental health assessments before THA. Measuring mindset using relatively brief instruments will be important considering the current shift toward implementing self-reported measures of health status in clinical practice and incorporating them within alternative payment models.

RESUMO

Hydroxyapatite crystal deposition disease (HADD) poses diagnostic challenges in the emergency department (ED) as it may clinically present similarly to infection and other musculoskeletal conditions. Misdiagnosis often leads to unnecessary treatments and resource over-utilization. This review article provides an overview of HADD in seven patients who presented to the ED secondary to an acute presentation of this disease process. HADD is a prevalent pathology, which commonly involves the shoulder, followed by the hip, elbow, wrist, and knee. Predisposing risk factors, such as diabetes and certain genetic factors, have also been identified. Clinical history and imaging, particularly radiographs, play a vital role in diagnosing HADD, with characteristic calcification patterns observed in different stages of the disease. Conservative nonsurgical therapy is the mainstay of treatment, providing effective symptom relief in over 90% of cases. By recognizing HADD as a crucial differential diagnosis for patients with acute or chronic pain, healthcare resource utilization can be optimized, leading to improved patient care in the ED.

RESUMO

INTRODUCTION: Pathway innovation using smartphone otoscopy and tablet-based audiometry technologies to deliver ear and hearing services via trained audiologists may improve efficiency of the service. An ENT-integrated-community-ear service (ENTICES-combining community audiology management, remote ENT review and novel technologies) was piloted. We aimed to assess the efficiency and safety of ENTICES. METHOD: ENTICES was a community-based and audiologist-led pathway. Patients with otological symptoms were self-referred to this service. Smartphone otoscopy and tablet-based audiograms were performed. Two otologists reviewed all decisions made in the community by audiologists based on video-otoscopy, hearing tests and chart reviews. Data on the first 50 consecutive new patients attending either consultant-led hospital otology clinics (HOC), audiologist-led hospital advanced audiology diagnostics (AAD) or ENTICES clinics were collected between 1 August 2021 and 31 December 2021. Data were collected through chart reviews and questionnaires to compare the three pathways with respect to efficiency, patient satisfaction, technology utility and safety. RESULTS: No audiology-led ENTICES decisions were amended by hospital otologists following remote review. Remote review of video-otoscopy with history was sufficient for a diagnosis in 80% of cases. Adding hearing tests and standardised history increased the diagnostic yield to 98%. Patient satisfaction scores showed 100% service recommendation. The cost per patient, per visit, was £83.36, £99.07 and £69.72 for AAD, HOC or ENTICES, respectively. CONCLUSION: ENTICES provides a safe ear and hearing service that patients rated highly. Thirty-two per cent of hospital otology patients were eligible for this service. For those patients, ENTICES is 20% more cost-effective and can reduce the number of clinic visits by up to 60% compared with HOC.

RESUMO

OBJECTIVES: To predict and identify the key demographic and clinical exposure factors associated with dental anxiety among young adults, and to compare if the traditional statistical modelling approach provides similar results to the machine learning (ML) approach in predicting factors for dental anxiety. METHODS: A cross-sectional study of Western Illinois University students. Three survey instruments (sociodemographic questionnaire, modified dental anxiety scale (MDAS), and dental concerns assessment tool (DCA)) were distributed via email to the students using survey monkey. The dependent variable was the mean MDAS scores, while the independent variables were the sociodemographic and dental concern assessment variables. Multivariable analysis was done by comparing the classical statistical model and the machine learning model. The classical statistical modelling technique was conducted using the multiple linear regression analysis and the final model was selected based on Akaike information Criteria (AIC) using the backward stepwise technique while the machine learining modelling was performed by comparing two ML models: LASSO regression and extreme gradient boosting machine (XGBOOST) under 5-fold cross-validation using the resampling technique. All statistical analyses were performed using R version 4.1.3. RESULTS: The mean MDAS was 13.73 ± 5.51. After careful consideration of all possible fitted models and their interaction terms the classical statistical approach yielded a parsimonious model with 13 predictor variables with Akaike Information Criteria (AIC) of 2376.4. For the ML approach, the Lasso regression model was the best-performing model with a mean RMSE of 0.617, R2 of 0.615, and MAE of 0.483. Comparing the variable selection of ML versus the classical statistical model, both model types identified 12 similar variables (out of 13) as the most important predictors of dental anxiety in this study population. CONCLUSION: There is a high burden of dental anxiety within this study population. This study contributes to reducing the knowledge gap about the impact of clinical exposure variables on dental anxiety and the role of machine learningin the prediction of dental anxiety. The predictor variables identified can be used to inform public health interventions that are geared towards eliminating the individual clinical exposure triggers of dental anxiety are recommended.

RESUMO

There has been increasing pressure on healthcare providers to exhibit restraint when prescribing opioids for pain control. However, data that characterizes the differences between orthopaedic providers and their accompanying prescription rates is not well developed. This study accessed Medicare Provider Utilization and Payment Data from 2015 to collect the number of prescriptions for opioid-based medications administered by orthopaedic surgeons across the country. A total of 19,410 orthopaedic providers were identified as opioid prescribers from the 2015 Medicare Part D Database. Providers averaged an opioid prescription every 10.9 days, with 94.7% of prescribers (18,387) having written more than 10 opioid prescriptions. Regionally, the Southern United States had the highest percentage of providers prescribing an opioid greater than 10 times at 96.4%. Female orthopaedic surgeons prescribed just over half the number of scripts that male surgeons did (79.4 vs. 154.2, p < 0.001). (Journal of Surgical Orthopaedic Advances 32(3):199-201, 2023).

RESUMO

Limited research demonstrates the possible correlations between dental diseases and neurodegenerative diseases like Alzheimer's disease (AD) and Parkinson's disease (PD). Nevertheless, dental diseases are often overlooked while assessing the risk of AD and PD in clinical settings. It is unknown whether AD/PD risk can be predicted using electronic dental record (EDR) data collected in a routine dental setting. This pilot study determined the feasibility of predicting AD/PD using 84 features routinely captured in the EDR. We utilized the Temple University School of Dentistry clinic data of 27,138 patients. Using a natural language processing (NLP) approach (accuracy=97%), we identified patients with AD/PD and their matched controls (matched by age and gender). XGBoost machine learning model with 10-fold cross-validation was applied for prediction. With 77% accuracy, we found 53 features significantly associated with AD/PD that could be utilized to predict the risk of AD/PD. Further studies are warned to confirm these findings.

RESUMO

The Impella 5.5 (Abiomed) is a percutaneous, temporary left ventricular assist device (LVAD) that serves as an important method of treatment of acute cardiogenic shock refractory to medical management. The Impella 5.5 and 5.0 are commonly inserted through the right axillary artery; however, this may be limited by inadequate vessel diameter to accommodate the Impella and inadequate vessel quality. A central approach to Impella 5.5 incision has been described in the pediatric population, particularly via the innominate artery through a suprasternal and/or neck incision, with success. As an alternative to axillary Impella placement, we propose the usage of a limited suprasternal incision for Impella 5.5 insertion in the adult population, either through the proximal right subclavian artery or the distal innominate artery. This may offer multiple advantages, such as increased vessel diameter and quality of more proximal vessels, avoidance of partial sternotomy, avoidance of a second infraclavicular wound site if the patient progresses to require LVAD or transplant, avoidance of lymphatic and nerve injury through the axillary exposure, ease of manipulation for repositioning, and patient rehabilitation. Potential limitations include difficulty due to body habitus, potential risk of stroke with the innominate approach, and wound complications. A central approach is a reasonable alternative to axillary Impella placement in patients with inadequate axillary artery caliber, defined as less than 6-7 mm diameter, poor artery quality to accommodate anastomosis, and small body habitus, allowing for ease of exposure.

RESUMO

BACKGROUND: Atrial fibrillation (AF) significantly contributes to acute ischemic stroke, with undetected AF being a common culprit in cryptogenic strokes. N-terminal pro-B-type natriuretic peptide (NT-proBNP), indicative of myocardial stress, has been proposed as a biomarker for AF detection, aiding in the selection of patients for extended cardiac monitoring. However, the diagnostic accuracy of NT-proBNP remains uncertain. METHODS: We conducted a meta-analysis to evaluate the diagnostic accuracy of NT-proBNP in detecting AF among cryptogenic stroke patients. A comprehensive literature search was conducted across PubMed, Embase, and Cochrane databases to identify relevant studies. Studies reporting NT-proBNP levels in stroke patients and data on the proportion of patients with AF above a specified cut-off were included. Meta-analyses were performed using the midas command in STATA. RESULTS: Seven studies encompassing 2171 patients were included in the analysis, of which five studies contained cohorts with cryptogenic strokes. Among patients with cryptogenic stroke, NT-proBNP demonstrated a diagnostic accuracy of 80% (Area Under the Receiver Operating Curve 0.80 [95% CI 0.76-0.83]), with a sensitivity of 81% (95% CI 0.68-0.89) and a specificity of 68% (95% CI 0.60-0.75). CONCLUSION: Our meta-analysis indicates that NT-proBNP exhibits a good-to-very-good diagnostic accuracy for detecting AF in patients with cryptogenic stroke. These findings suggest potential implications for utilizing NT-proBNP in guiding the selection of patients for prolonged cardiac monitoring, thereby aiding in the management of cryptogenic stroke cases.

RESUMO

OBJECTIVE: Idiopathic intracranial hypertension (IIH) is a cerebrospinal fluid (CSF) disorder defect that is frequently treated with CSF shunts. Shunts utilizing the cisterna magna as a proximal reservoir have been described in literature; however, long-term outcomes are unknown. The present study aims to describe the long-term effectiveness, revision rates, and clinical outcomes of this shunt in 14 patients with IIH and slit ventricles. METHODS: A single-center retrospective review of 14 IIH patients treated by cisterna magna shunts was performed. Shunt histories, including revision rate and time until first shunt failure for ventricular, lumbar, and cisterna magna shunts were recorded. "Revision rate" was calculated as the total number of shunt revisions over years of total shunt placement. The average follow-up time was 12.08 years. RESULTS: The mean age at first cisterna magna shunt placement was 18.1 years (6.6-43.3 years) and all patients had radiological evidence of slit ventricles. Cisterna magna shunts improved or resolved clinical symptoms for all 14 patients and had a lower rate of revisions (0.42 revision/year) compared to ventricular (0.72 revision/year) and lumbar (1.30 revision/year) shunts. Of the 11 patients still requiring CSF diversion at the end of the study, eight had functioning shunts that utilized the cisterna magna. CONCLUSIONS: The cisterna magna shunt may be a suitable option for patients with IIH and slit ventricles. Further study is needed to understand the clinical utility of this shunt for the population in which it is indicated.

RESUMO

Dengue, commonly referred to as 'breakbone fever,' is a mosquito-borne arboviral infection transmitted by Aedes aegypti, featuring an average incubation period of approximately seven days. Key cytokines such as interferon-gamma (IFN-γ), tumor necrosis factor (TNF)-α, and interleukin (IL)-10 are pivotal in the pathogenesis of dengue. Travelers are particularly susceptible to contracting dengue fever, with disease severity often associated with CD8+ T cell response. Without proper hospitalization during severe cases like dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS), mortality rates can escalate to 50%. Dengue fever can lead to various complications, including neurological manifestations such as encephalopathy, encephalitis, cerebral venous thrombosis, myelitis, posterior reversible encephalopathy syndrome, strokes (both ischemic and hemorrhagic), immune-mediated neurological syndromes (such as mononeuropathy, acute transverse myelitis, Guillain-Barre syndrome, and acute disseminated encephalomyelitis), and neuromuscular complications. Treatment protocols typically involve assessing disease activity using composite indices, pursuing treatment objectives, and administering intravenous fluids according to symptomatology. Given the absence of specific antiviral treatment for dengue, supportive care, particularly hydration, remains paramount during the early stages. It is crucial to recognize that dengue viruses may contribute to the development of neurological disorders, particularly in regions where dengue is endemic. Furthermore, there is a necessity for well-defined criteria for specific neurological complications. Primary prevention strategies primarily revolve around vector control measures, which play a critical role in curtailing the spread of dengue.
