Viral Conjunctivitis Rates Unchanged Before and During the COVID-19 Pandemic in an Ophthalmology Clinic.

Background: Millions of acute conjunctivitis cases occur in the United States annually. The impact of COVID-19 mitigation practices on viral conjunctivitis incidence within ophthalmology clinics has not been reported. We hypothesized that viral conjunctivitis rates would decrease with implementation of such practices. Methods: A retrospective chart review was conducted at a single academic center's ophthalmology clinics. Electronic health record data was queried using ICD-10 diagnostic codes to include 649 patients aged 2-97 with viral, bacterial, or allergic conjunctivitis diagnosed either before (6/1/2018-5/1/2019) or during (6/1/2020-5/1/2021) COVID-19 precautions. Conjunctivitis rates per ophthalmology clinic visit were compared using rate-ratio analysis. Logistic regression evaluated the effects of age, sex, and race among those with conjunctivitis. Results: A total of 66,027 ophthalmology clinic visits occurred during the study period. Viral conjunctivitis rates per visit did not significantly change after enacting COVID-19 mitigation strategies, but allergic conjunctivitis rates significantly increased (viral: RR 0.82, 95% CI 0.51 to 1.31, p=0.408; allergic: RR 1.70, 95% CI 1.43 to 2.03, p<0.001). When controlling for time, younger age (≤ median age 55) (p=0.005) and Caucasian race (p=0.009) were associated with higher viral conjunctivitis frequency. Conclusion: Contrary to trends reported in emergency departments, viral conjunctivitis rates within an ophthalmology clinic did not significantly change after COVID-19 mitigation strategies, though allergic conjunctivitis rates increased. Patients' avoidance of emergency departments during the pandemic may have contributed. Further investigation is required to explore variation in ophthalmology patient populations and needs based on care setting.

A retrospective review included 649 patients with viral, bacterial, or allergic conjunctivitis diagnosed at a single center's ophthalmology clinics before (6/1/2018­5/1/2019) or during (6/1/2020­5/1/2021) COVID-19 precautions. Contrary to emergency department experiences, viral conjunctivitis rates did not significantly change after COVID-19 precautions. However, allergic conjunctivitis rates significantly increased. Conjunctivitis presentation in ophthalmology clinics differed from that reported in emergency departments, warranting further evaluation of variation in patient needs by setting.

Association of Patient-Reported Social Needs with Emergency Department Visits and Hospitalizations Among Federally Qualified Health Center Patients.

BACKGROUND: Health care systems are increasingly screening for unmet social needs. The association between patient-reported social needs and health care utilization is not well understood. OBJECTIVE: To investigate the association between patient-reported social needs, measured by the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE), and inpatient and emergency department (ED) utilization. DESIGN: This cohort study analyzed merged 2017-2019 electronic health record (EHR) data across multiple health systems. PARTICIPANTS: Adult patients from a federally qualified health center (FQHC) in central North Carolina who completed PRAPARE as part of a primary care visit with behavioral health services. MAIN MEASURES: The count of up to 12 unmet social needs, aggregated as 0, 1, 2, or 3 + . Outcomes include the probability of an ED visit and hospitalization 12 months after PRAPARE assessment, modeled by logistic regressions controlling for age, sex, race, ethnicity, comorbidity burden, being uninsured, and prior utilization in the past 12 months. KEY RESULTS: The study population consisted of 1924 adults (38.7% male, 50.1% Black, 36.3% Hispanic, 55.9% unemployed, 68.2% of patients reported 1 + needs). Those with more needs were younger, more likely to be unemployed, and experienced greater comorbidity burden. 35.3% of patients had ED visit(s) and 36.3% had hospitalization(s) 1 year after PRAPARE assessment. In adjusted analysis, having 3 + needs was associated with a percentage point increase in the predicted probability of hospitalization (average marginal effect 0.06, SE 0.03, p < 0.05) compared with having 0 needs. Similarly, having 2 needs (0.07, SE 0.03, p < 0.05) or 3 + needs (0.06, SE 0.03, p < 0.05) was associated with increased probability of ED visits compared to 0 needs. CONCLUSIONS: Patient-reported social needs were common and associated with health care utilization patterns. Future research should identify interventions to address unmet social needs to improve health and avoid potentially preventable escalating medical intervention.

Autologous Matrix-Induced Chondrogenesis for the Treatment of Hip Acetabular Chondral Lesions Demonstrates Improved Outcomes: A Systematic Review.

PURPOSE: To systematically investigate the outcomes of patients who underwent autologous matrix-induced chondrogenesis (AMIC) during hip arthroscopy for the treatment of acetabular chondral lesions due to femoroacetabular impingement syndrome (FAIS). METHODS: PubMed and Cochrane were queried in June 2022 to conduct this systematic review using the following keywords: "femoracetabular impingement," "arthroscopy," "microfracture," and "autologous matrix-induced chondrogenesis." Articles were included if they reported on patient-reported outcomes of AMIC during hip arthroscopy to treat chondral lesions of the hip. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) criteria. Each study was queried for demographics, lesion classification, surgical treatment, patient-reported outcome scores, revision arthroscopy, and conversion to THA. A qualitative sub-analysis was performed to compare patients undergoing AMIC to patients undergoing microfracture alone if included studies also assessed results of microfracture alone. RESULTS: Four studies met inclusion criteria and assessed 209 hips undergoing AMIC. The included studies consisted of 99 male and 110 female patients. Mean postoperative follow-up ranged from 1 to 8 years, and mean patient age ranged from 34.3 to 45 years. Three of the four included studies reported the modified Harris Hip Scores (mHHS) and all three of these studies reported statistically significant improvement in the mHHS at final follow-up (p<0.001) with mean preoperative values ranging from 44.5-62.8 and mean postoperative values ranging from 78.8-95.8. Two of the four studies compared patients treated with AMIC to microfracture alone. In these two studies, the AMIC groups reported 0 patients converting to THA while the microfracture alone groups reported a highly variable rate of conversion to THA (2% - 32.6%). CONCLUSION: Patients who underwent hip arthroscopy and AMIC for the treatment of FAIS and acetabular chondral lesions demonstrated improved patient reported outcomes and low rates of secondary surgeries at short-term follow-up.

Clinical genetics in breast cancer.

As genetic testing becomes increasingly more accessible and more applicable with a broader range of clinical implications, it may also become more challenging for breast cancer providers to remain up-to-date. This review outlines some of the current clinical guidelines and recent literature surrounding germline genetic testing, as well as genomic testing, in the screening, prevention, diagnosis, and treatment of breast cancer, while identifying potential areas of further research.

Coronary intravascular lithotripsy for severe coronary artery calcification: The disrupt CAD I-IV trials.

Coronary artery calcification (CAC) severity is associated with increased vessel inflammation, atherosclerosis, stent failure, and risk of percutaneous coronary intervention-related complications. Current modalities for CAC modification include atherectomy techniques (rotational, orbital, and laser) and balloon modification (cutting and scoring). However, these methods are limited by their risk of slow flow/no reflow, coronary dissection, perforation, and myocardial infarction. Intravascular lithotripsy (IVL) emits high-energy sonic waves that induce calcium fractures within a target lesion to improve vessel compliance for stent placement. Low rates of major cardiac adverse events (MACE) and high rates of procedural and angiographic success were observed with IVL in the Disrupt CAD I-IV trials. Optical coherence tomography sub-studies identified calcium fracture as the likely etiology of improved vessel compliance and increased luminal diameter post-IVL. Rates of MACE, procedural, and angiographic success were consistent across the Disrupt CAD trials, suggesting IVL is less operator-dependent compared to other calcium-modifying techniques. Coronary IVL offers interventional cardiologists a safe and effective method of severe CAC modification, while providing reproducible outcomes.

Female Patients Undergoing Latarjet Surgery Show Similar 2-Year Secondary Surgery Rates but Greater Risk of Emergency Department Visits Compared With a Matched Cohort of Male Patients.

PURPOSE: To evaluate sex-based differences in 30-day postoperative emergency department (ED) visits, 90-day complication rates, and 2-year secondary surgery rates after the Latarjet procedure for the treatment of recurrent shoulder instability. METHODS: A national administrative claims database was used to identify patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for shoulder subluxation or dislocation on the day of first-time stabilization with the Latarjet technique between 2015 and 2021. Male patients were matched 4:1 to female patients based on age, Elixhauser Comorbidity Index (ECI) score, and body mass index class. Rates of 30-day ED visits and 90-day complications were compared between cohorts, and risk factors for ED visits were identified by multivariate regression. The incidence of secondary surgery within 2 years was compared by Kaplan-Meier analysis. RESULTS: Prior to matching, 1,059 male and 360 female patients met the inclusion and exclusion criteria. Subsequent 4:1 (male-to-female) matching controlling for age, ECI score, and body mass index yielded 694 male and 185 female patients who underwent the Latarjet procedure. The overall incidence of 30-day ED visits was 9.3%, with an incidence of 8.2% for male patients and 13.5% for female patients. On the basis of multivariate logistic regression, these 30-day ED visits were associated with female sex (odds ratio, 1.79; P = .029) and incrementally higher ECI scores; relative to an ECI score of 0, ECI scores of 1 to 2, 3 to 4, and 5 or greater were associated with odds ratios of 5.31 (P = .006), 8.12 (P < .001), and 12.84 (P < .001), respectively. Ninety-day complications occurred in 1.5% of the total cohort, and the incidence was not statistically different between sexes. Overall, 2-year secondary surgery rates were similar between male and female patients (5.1% and 6.7%, respectively; P = .4). CONCLUSIONS: Female patients undergoing the Latarjet procedure for recurrent shoulder instability showed similar 90-day complication and 2-year secondary surgery rates to a matched cohort of male patients. Female sex, along with ECI score, however, was associated with a greater rate of 30-day ED visits. LEVEL OF EVIDENCE: Level III, retrospective comparative case series.

Osteochondral Allograft or Autograft Transplantation of the Femoral Head Leads to Improvement in Outcomes but Variable Survivorship: A Systematic Review.

PURPOSE: To review patient-reported outcomes (PROs) and survivorship in patients undergoing osteochondral autograft or allograft transplantation (OAT) of the femoral head. METHODS: PubMed, Cochrane Center for Register of Controlled Trials, and Scopus databases were searched in November 2022 with an updated search extending to December 2023 using criteria from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the following keywords: (hip OR femoral head) AND (mosaicplasty OR osteochondral allograft OR osteochondral autograft OR osteochondral lesion). Articles were included if they evaluated postoperative PROs in patients who underwent OAT of the femoral head and had a study size of 5 or more hips (n ≥ 5). Survivorship was defined as freedom from conversion to total hip arthroplasty. For PROs evaluated in 3 studies or more, forest plots were created and I2 was calculated. RESULTS: Twelve studies were included in this review, with a total of 156 hips and a mean follow-up time ranging between 16.8 and 222 months. In total, 104 (66.7%) hips were male while 52 (33.3%) were female. Age of patients ranged from 17.0 to 35.4 years, while body mass index ranged from 23.3 to 28.1. Eight studies reported on osteochondral autograft transplantation and 4 studies on osteochondral allograft transplantation. Three studies reported significant improvement in at least 1 PRO. Survivorship ranged from 61.5% to 96% at minimum 2-year follow-up and from 57.1% to 91% at minimum 5-year follow-up. At a follow-up of less than 5 years, osteochondral allograft transplantation studies showed 70% to 87.5% survivorship, while autograft varied from 61.54% to 96%. CONCLUSIONS: Patients with osteochondral lesions of the femoral head who underwent osteochondral autograft or allograft transplantation demonstrated improved PROs but variable survivorship rates. LEVEL OF EVIDENCE: Level IV, systematic review of Level IV studies.

Impact of KRAS mutations and co-mutations on clinical outcomes in pancreatic ductal adenocarcinoma.

The relevance of KRAS mutation alleles to clinical outcome remains inconclusive in pancreatic adenocarcinoma (PDAC). We conducted a retrospective study of 803 patients with PDAC (42% with metastatic disease) at MD Anderson Cancer Center. Overall survival (OS) analysis demonstrated that KRAS mutation status and subtypes were prognostic (p < 0.001). Relative to patients with KRAS wildtype tumors (median OS 38 months), patients with KRASG12R had a similar OS (median 34 months), while patients with KRASQ61 and KRASG12D mutated tumors had shorter OS (median 20 months [HR: 1.9, 95% CI 1.2-3.0, p = 0.006] and 22 months [HR: 1.7, 95% CI 1.3-2.3, p < 0.001], respectively). There was enrichment of KRASG12D mutation in metastatic tumors (34% vs 24%, OR: 1.7, 95% CI 1.2-2.4, p = 0.001) and enrichment of KRASG12R in well and moderately differentiated tumors (14% vs 9%, OR: 1.7, 95% CI 1.05-2.99, p = 0.04). Similar findings were observed in the external validation cohort (PanCAN's Know Your Tumor® dataset, n = 408).

Comprehensive Landscape of BRAF Variant Classes, Clonalities, and Co-Mutations in Metastatic Colorectal Cancer Using ctDNA Profiling.

Although V600E accounts for the majority of the BRAF mutations in metastatic colorectal cancer (mCRC), non-V600 BRAF variants have been shown in recent years to represent a distinct molecular subtype. This study provides a comprehensive profile of BRAF variants in mCRC using a large genomic database of circulating tumor DNA (ctDNA) and analyzing clinical outcomes in a cohort of patients with atypical (non-V600) BRAF variants (aBRAF; class II, class III, unclassified). Overall, 1733 out of 14,742 mCRC patients in the ctDNA cohort had at least one BRAF variant. Patients with atypical BRAF variants tended to be younger and male. In contrast to BRAFV600E, BRAF class II and III variants and their co-occurrence with KRAS/NRAS mutations were increased at baseline and especially with those patients predicted to have prior anti-EGFR exposure. Our clinical cohort included 38 patients with atypical BRAF mCRC treated at a large academic referral center. While there were no survival differences between atypical BRAF classes, concurrent RAS mutations or liver involvement was associated with poorer prognosis. Notably, patients younger than 50 years of age had extremely poor survival. In these patients, the high-frequency KRAS/NRAS co-mutation and its correlation with poorer prognosis underlines the urgent need for novel therapeutic strategies. This study represents one of the most comprehensive characterizations to date of atypical BRAF variants, utilizing both ctDNA and clinical cohorts.

Corticosteroid Injections Administered Within 4 Weeks Prior to Hip Arthroscopy Are Associated With Higher Rates of Postoperative Infection.

PURPOSE: To evaluate the association between the timing of intra-articular hip corticosteroid injections and the risk of postoperative infection in patients undergoing hip arthroscopy. METHODS: The 2010-2021 PearlDiver M157 administrative claims database was queried for patients who underwent hip arthroscopy. Patients who received intra-articular corticosteroid injections within 12 weeks prior to arthroscopy were matched 1:1 to patients who did not receive such injections based on age, sex, and Elixhauser Comorbidity Index, as well as the presence of diabetes mellitus, hypertension, obesity, and tobacco use. Those with injections prior to arthroscopy were subdivided based on having received injections within 12 weeks prior to surgery. To verify that the corticosteroid injections and surgical procedures were conducted in the hip joint, Current Procedural Terminology codes were used. By use of Current Procedural Terminology and International Classification of Diseases (ninth revision and tenth revision) coding, postoperative surgical-site infection after corticosteroid injection was evaluated. The impact of the timing of preoperative corticosteroid injections on the incidence of postoperative infection was evaluated using multivariable logistic regression analysis. RESULTS: A total of 12,390 hip arthroscopy cases were identified, including 3,579 patients who received corticosteroid injections 0 to 4 weeks prior to surgery; 4,759, within 4 to 8 weeks prior to surgery; and 4,052, within 8 to 12 weeks prior to surgery. Compared with controls, patients who received corticosteroid injections within 0 to 4 weeks preoperatively had a significantly higher rate of surgical-site infection (odds ratio, 2.43; P = .0001). No significant differences in infection rates were observed at the later time intervals (4-8 weeks or 8-12 weeks). Furthermore, in comparison to controls, patients who received corticosteroid injections had a significantly higher rate of wound dehiscence (odds ratio, 1.84; P = .0007). CONCLUSIONS: Intra-articular corticosteroid injections within 4 weeks prior to hip arthroscopy were significantly associated with increased surgical-site infection rates after hip arthroscopy surgery. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Establishing Optic Nerve Diameter Threshold Sensitive and Specific for Optic Atrophy Diagnosis.

PURPOSE: To determine a potential threshold optic nerve diameter (OND) that could reliably differentiate healthy nerves from those affected by optic atrophy (OA) and to determine correlations of OND in OA with retinal nerve fiber layer (RNFL) thickness, visual acuity (VA), and visual field mean deviation (VFMD). METHODS: This was a retrospective case control study. Magnetic resonance (MR) images were reviewed from individuals with OA aged 18 years or older with vision loss for more than 6 months and an OA diagnosis established by a neuro-ophthalmologist. Individuals without OA who underwent MR imaging of the orbit for other purposes were also collected. OND was measured on coronal T2-weighted images in the midorbital section, 1cm posterior to the optic disc. Measurements of mean RNFL thickness, VA and VFMD were also collected. RESULTS: In this study 47 OA subjects (63% women, 78 eyes) and 75 normal subjects (42.7% women, 127 eyes) were assessed. Healthy ONDs (mean 2.73 ± 0.24 mm) were significantly greater than OA nerve diameters (mean 1.94 ± 0.32 mm; P < 0.001). A threshold OND of ≤2.3 mm had a sensitivity of 0.92 and a specificity of 0.93 in predicting OA. Mean RNFL (r = 0.05, p = 0.68), VA (r = 0.17, p = 0.14), and VFMD (r = 0.18, p = 0.16) were not significantly associated with OND. CONCLUSION: ONDs are significantly reduced in patients with OA compared with healthy nerves. A threshold OND of ≤2.3 mm is highly sensitive and specific for a diagnosis of OA. OND was not significantly correlated with RNFL thickness, VA, or VFMD.

Heparin Dosing During Percutaneous Coronary Intervention and Obesity.

ABSTRACT: Unfractionated heparin is the most common anticoagulant used during percutaneous coronary intervention. Practice guidelines recommend an initial weight-based heparin bolus dose between 70 and 100 U/kg to achieve target activated clotting time (ACT) of 250-300 seconds. The impact of severe obesity on weight-based heparin dosing is not well studied. We performed a retrospective analysis of 424 patients undergoing percutaneous coronary intervention who received heparin for anticoagulation. We collected detailed data on cumulative heparin administration and measured ACT values in this cohort. We performed separate analyses to identify clinical predictors that may affect dose-response curves. There was significant variability in dosing with mean dose of 103.9 ± 32-U/kg heparin administered to achieve target ACT ≥ 250 seconds. Women received higher initial heparin doses when adjusted for weight than men (97.6 ± 31 vs. 89 ± 28 U/kg, P = 0.004), and only 49% of patients achieved ACT ≥ 250 s with the initial recommended heparin bolus dose (70-100 U/kg). Lower heparin dose (U/kg) was required in obese patients to achieve target ACT. In multivariate linear regression analysis with ACT as dependent variable, after inclusion of weight-based dosing for heparin, body mass index was the only significant covariate. In conclusion, there is significant variability in the therapeutic effect of heparin, with a lower weight-adjusted heparin dose required in obese patients.

A multi-centre case series of patients with coexistent intracranial hypertension and malignant arterial hypertension.

OBJECTIVE: To describe the clinical characteristics, outcomes, and management of a large cohort of patients with concomitant malignant arterial hypertension and intracranial hypertension. METHODS: Design: Retrospective case series. SUBJECTS: Patients aged ≥ 18 years with bilateral optic disc oedema (ODE), malignant arterial hypertension and intracranial hypertension at five academic institutions. Patient demographics, clinical characteristics, diagnostic studies, and management were collected. RESULTS: Nineteen patients (58% female, 63% Black) were included. Median age was 35 years; body mass index (BMI) was 30 kg/m2. Fourteen (74%) patients had pre-existing hypertension. The most common presenting symptom was blurred vision (89%). Median blood pressure (BP) was 220 mmHg systolic (IQR 199-231.5 mmHg) and 130 mmHg diastolic (IQR 116-136 mmHg) mmHg), and median lumbar puncture opening pressure was 36.5 cmH2O. All patients received treatment for arterial hypertension. Seventeen (89%) patients received medical treatment for raised intracranial pressure, while six (30%) patients underwent a surgical intervention. There was significant improvement in ODE, peripapillary retinal nerve fibre layer thickness, and visual field in the worst eye (p < 0.05). Considering the worst eye, 9 (47%) presented with acuity ≥ 20/25, while 5 (26%) presented with ≤ 20/200. Overall, 7 patients maintained ≥ 20/25 acuity or better, 6 demonstrated improvement, and 5 demonstrated worsening. CONCLUSIONS: Papilloedema and malignant arterial hypertension can occur simultaneously with potentially greater risk for severe visual loss. Clinicians should consider a workup for papilloedema among patients with significantly elevated blood pressure and bilateral optic disc oedema.

Dancers Show Significant Improvement in Outcomes and Favorable Return-to-Dance Rates After Primary Hip Arthroscopy With Femoral Head Cartilage Status Being a Predictor of Secondary Surgical Procedures at Mid-Term Follow-Up.

PURPOSE: To report minimum 5-year follow-up patient-reported outcome measurement (PROM) scores and return-to-dance rates in dancers who underwent primary hip arthroscopy and to identify predictors of secondary surgical procedures. METHODS: Prospectively collected data from patients who underwent hip arthroscopy between May 2010 and June 2016 were retrospectively reviewed. Patients were included if they participated in dance at any level 1 year prior to surgery and had preoperative and minimum 5-year follow-up scores consisting of the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale pain score. The exclusion criteria were previous hip conditions, previous ipsilateral hip surgery, Tönnis grade greater than 1, or lateral center-edge angle less than 18°. The minimal clinically important difference (MCID) was reported. Dancers who discontinued dance for reasons other than pain in the operative hip were excluded from the return-to-dance analysis. A logistic regression model was used to identify predictors of secondary surgical procedures. RESULTS: Fifty-one hips (48 female dancers) were included. The average age and average follow-up period were 29.8 ± 17.2 years and 79.1 ± 23.2 months, respectively. Improvement in all PROM scores (P < .001) was reported. Achievement rates of the MCID for the modified Harris Hip Score, Nonarthritic Hip Score, and visual analog scale pain score were 83.3%, 85.7%, and 85.7%, respectively. Revision hip arthroscopy was performed in 5 dancers (9.8%). Conversion to total hip arthroplasty was performed in 4 dancers (7.8%). The return-to-dance rate was 78.6%, with 57.6% returning to the preinjury performance level or a higher level. Higher femoral head Outerbridge grade was identified as a predictor of secondary surgical procedures (P = .045; odds ratio, 6.752 [95% confidence interval, 1.043-43.688]). CONCLUSIONS: After primary hip arthroscopy, dancers experienced significant improvement in all PROM scores collected and achieved the MCID at a high rate at minimum 5-year follow-up. The return-to-dance rate in dancers who did not discontinue dance because of lifestyle transitions was 78.6%, with 57.6% returning to the preinjury performance level or a higher level. Higher femoral head Outerbridge grade was found to be a predictor of secondary surgical procedures. LEVEL OF EVIDENCE: Level IV, case series.

Medicaid Insurance Is Associated With More Complications and Emergency Department Visits but Equivalent 5-Year Secondary Surgery Rate After Primary Hip Arthroscopy.

PURPOSE: To compare 90-day complications, 30-day emergency department (ED) visits, and 5-year rate of secondary surgeries for patients with Medicaid vs commercial insurance undergoing primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and/or labral tears using a large national database. METHODS: The PearlDiver Mariner151 database was used to identify patients with International Classification of Diseases, Tenth Revision diagnosis codes for FAIS and/or labral tear who underwent primary hip arthroscopy with femoroplasty, acetabuloplasty, and/or labral repair between 2015 and 2021. Patients with Medicaid were matched 1:4 to a control group of commercially insured patients based on age, sex, body mass index, and Elixhauser Comorbidity Index. Rates of 90-day complications and 30-day ED visits were compared using multivariate regression models. Five-year rates of secondary surgeries-revision arthroscopy or total hip arthroplasty-were compared between cohorts by Kaplan-Meier analysis. RESULTS: A total of 2,033 Medicaid patients were matched with 8,056 commercially insured patients. Rates of adverse events were low; however, Medicaid patients were significantly more likely than commercially insured patients to experience any 90-day complication (2.12% vs 1.43%; odds ratio [OR], 1.2; P = .02). Medicaid patients also experienced more 30-day ED visits than commercially insured patients (8.61% vs 4.28%), and on multivariate logistic regression, insurance status was the strongest determinant of 30-day ED visits (relative to commercial, Medicaid OR, 2.02; P < .001). Despite these differences, 5-year rates of secondary surgeries were comparable between groups (6.1% vs 6.0%; P = .6). CONCLUSIONS: In this large national database study, Medicaid patients undergoing primary hip arthroscopy showed significantly greater odds of experiencing 90-day postoperative complications and 30-day ED visits compared to commercially insured patients. Nevertheless, both groups had similar survivorship rates at 5-year follow-up, similar to prior estimates irrespective of insurance. These results document encouraging secondary surgery rates in Medicaid patients.

Glenohumeral Superior Translation and Subacromial Contract Pressure Are Both Improved With Superior Capsular Reconstruction: A Systematic Review and Meta-analysis of Biomechanical Investigations.

PURPOSE: To review cadaveric studies evaluating the biomechanical outcomes of superior capsular reconstruction (SCR) with different graft types for the treatment of irreparable rotator cuff (RTC) tears. METHODS: PubMed, Cochrane, and Embase were queried in January 2022 to conduct this meta-analysis using the following key words: "superior capsule reconstruction," "superior capsular reconstruction," and "biomechanics." Articles were included if they reported glenohumeral superior translation or subacromial contact pressure following SCR in cadaveric RTC tears. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. Number of shoulders, graft types, and biomechanical outcomes were recorded and analyzed with forest plots. RESULTS: Twelve studies (95 shoulders) were included in the statistical analysis. There was a significant reduction in glenohumeral superior translation following SCR compared with RTC tear across 10 studies (79 shoulders) with standardized mean difference (SMD) -2.48 mm; confidence interval (CI) -3.28 mm, -1.69 mm. The SMD between fascia lata graft and RTC tear was -3.84 mm (CI -4.82 mm, -2.86 mm) and between dermal allograft and RTC tear was -2.05 mm (CI -3.10 mm, -1.00 mm). There was a significant reduction in subacromial contact pressure following SCR compared with RTC tear across 5 studies (55 shoulders) with SMD -3.49 MPa (CI -4.54 MPa, -2.44 MPa). The SMD between fascia lata graft and RTC tear was -3.21 MPa (CI -5.08 MPa, -1.34 MPa) and between dermal allograft and RTC tear was -3.89 MPa (CI -5.91 MPa, -1.87 MPa). CONCLUSIONS: Independent of graft type, biomechanical studies suggest that SCR improves glenohumeral superior translation and subacromial contact pressure in comparison with RTC tear at time zero. There was no definitive evidence identified in this study to suggest a biomechanically superior SCR graft option. CLINICAL RELEVANCE: Investigating the biomechanical outcomes of several graft types for superior capsular reconstruction will help surgeons better understand the efficacies of different graft types for use in superior capsule reconstruction surgery.

Predictors of Ophthalmology Resident Performance From Medical Student Application Materials.

OBJECTIVE: To determine whether elements in ophthalmology residency applications are predictors of future resident performance. DESIGN: This multi-institutional, cross-sectional, observational study retrospectively reviewed the residency application materials of ophthalmology residents who graduated from residency from 2006 through 2018. Resident performance was scored by 2 faculty reviewers in 4 domains (clinical, surgical, academic, and global performance). Correlation between specific elements of the residency application and resident performance was assessed by Spearman correlation coefficients (univariate) and linear regression (multivariate) for continuous variables and logistic regression (multivariate) for categorical variables. SETTING: Seven ophthalmology residency programs in the US. PARTICIPANTS: Ophthalmology residents who graduated from their residency program. RESULTS: High-performing residents were a diverse group, in terms of sex, ethnicity, visa status, and educational background. Residents with United States Medical Licensing Examination Step 1 scores higher than the national average for that year had significantly higher scores in all 4 performance domains than those who scored at or below the mean (all domains P < 0.05). Residents who had honors in at least 4 core clerkships and who were members of Alpha Omega Alpha Medical Honor Society also had higher scores in all 4 performance domains (all domains P ≤ 0.04). Step 1 score (ρ=0.26, P < 0.001) and the difference between Step 1 score and the national average for that year (ρ=0.19, P = 0.009) positively correlated with total resident performance scores. Residents who passed the American Board of Ophthalmology Written Qualifying Examination or Oral Examination on their first attempt had significantly higher Step 1/2 scores (P ≤ 0.005), Ophthalmology Knowledge Assessment Program scores (P = 0.001), and resident performance scores (P ≤ 0.004). CONCLUSIONS: In this new landscape of increasing numbers of applicants to residency programs and changing of the Step 1 score to pass/fail, our findings may help guide selection committees as they holistically review applicants to select exceptional future residents in ophthalmology.

Social Media and Digital Footprints in Orthopaedic Trauma: An Analysis of 1465 Orthopaedic Trauma Association Members.

OBJECTIVES: The purpose of this study was to quantify social media usage among Orthopaedic Trauma Association (OTA) members. METHODS: All active OTA members were searched for involvement among common social media platforms. Surgeons were then classified as "active" on any given social media site if they posted within the past 6 months. Surgeons were also identified by the region they practiced in, sex, and their practice setting (academic vs. private). Finally, a surgeon's score and number of reviews from common physician review websites were examined. RESULTS: A total of 1465 OTA members were included in the analysis. Most surgeons were male (89.1% [n = 1305]) and practiced in a private setting (54.5% [n = 799]). A total of 590 surgeons (40.3%) had at least one form of social media account. Social media sites most used were LinkedIn with 48.7% (n = 713) and ResearchGate with 29.2% (n = 428). Academic surgeons were more likely to have a ResearchGate, LinkedIn, and Twitter account while private surgeons were more likely to have a personal website ( P < 0.05). Finally, there was no correlation between surgeons more active on social media and average scores on Vitals.com or Healthgrade.com ( P > 0.05). CONCLUSIONS: Most orthopaedic trauma surgeons do not have professional social media accounts. Although social media may help spread scholarship, having a professional social media account does not correlate with better online physician reviews or increased online reviews among orthopaedic trauma surgeons.

Sustained Disease Control in Immune Checkpoint Blockade Responders with Microsatellite Instability-high Colorectal Cancer after Treatment Termination.

Immune checkpoint inhibitors improve survival in patients with mismatch repair deficiency/microsatellite instability-high (MSI-H) colorectal cancer. The recurrence outcomes following discontinuation of immunotherapy after prolonged disease control have not been definitively reported in large series. Records from patients with advanced MSI-H colorectal cancer from The University of Texas - MD Anderson Cancer Center who received immunotherapy between 2014 and 2022 and stopped after prolonged clinical benefit were reviewed. Median progression-free and overall survival were estimated. Associations between the event of recurrence and coexisting mutations (KRAS/NRAS, BRAFV600E), metastatic organ involvement (lung, liver, lymph node, or peritoneum), metastatic timing (synchronous vs. metachronous), prior immunotherapy [anti-PD-(L)1 alone or in combination with anti-CTLA antibodies], etiology of MSI status (sporadic vs. hereditary non-polyposis colorectal cancer), and duration of immunotherapy were assessed. Sixty-four patients with MSI-H colorectal cancer without progression on immunotherapy were reviewed. Of these 48 and 16 received anti-PD(L)1 antibody alone or in combination with anti-CTLA-4 antibody, respectively. Median exposure to immunotherapy was 17.6 months (range, 1.3-51.9). After a median follow-up of 22.6 months (range, 0.3-71.7) after stopping immunotherapy, 56 of 64 patients (88%) remained without disease progression. Lung metastases were associated with recurrence/progression (OR, 6.1; P = 0.04), but coexisting mutation, primary tumor sidedness, and immunotherapy were not. These data provide a retrospective, single-institution analysis that showed that most patients with advanced MSI-H colorectal cancer do not recur after treatment cessation, regardless of the reason for stopping treatment or a variety of patient and disease features, supporting an optimistic prognosis of sustained disease control. SIGNIFICANCE: Outcomes for patients with MSI-H colorectal cancer stopping immunotherapy after disease control remain unknown. Sixty-four patients with MSI-H colorectal cancer from our institution stopping treatment for sustained benefit or toxicity were retrospectively assessed. After median follow up of 22 months and median immunotherapy exposure of 18 months, 88% patients remained without progression. All patients who recurred or progressed and were rechallenged with immunotherapy have continued to experience disease control.

Patients Undergoing Revision Hip Arthroscopy With Labral Reconstruction or Augmentation Demonstrate Favorable Patient Reported Outcomes: A Systematic Review.

PURPOSE: To review current literature evaluating patient-reported outcomes (PROs) and survivorship in patients undergoing revision hip arthroscopy with labral reconstruction or augmentation. METHODS: A systematic review was performed with the following key words: (revision) AND (hip OR femoroacetabular impingement) AND (arthroscopy OR arthroscopic) AND (reconstruction OR augmentation OR irreparable). PubMed, Cochrane Trials, and Scopus were queried in October 2022 using the criteria established in the Preferred Reporting Items for Systematic Reviews and Meta-analyses. Studies were included if they involved patients undergoing revision hip arthroscopy with labral reconstruction or augmentation and reported preoperative and postoperative PROs at minimum 2-year follow-up. Only original research articles were included. Survivorship was defined as a nonconversion to total hip arthroplasty. Outcomes present in 3 or more studies underwent further statistical analysis with forest plots. Heterogeneity of studies was evaluated using the I2 statistic. RESULTS: Five studies were reviewed, including 359 revision hip arthroscopies (335 with complete follow-up) with a follow-up that ranged from 2.2 to 5.2 years. Four studies reported on outcomes after revision labral reconstruction and 1 study reported on labral augmentation. Two out of 5 included studies evaluated for statistical significance between preoperative and postoperative outcomes. Three out of 5 studies reported a rate of at least 70% for achieving minimal clinically important difference in at least 1 PRO. At minimum 2-year follow-up, survivorship ranged from 93.5% to 100%. CONCLUSIONS: Patients that underwent revision hip arthroscopy with labral reconstruction or augmentation demonstrated improvement in PROs with mixed rates of achieving clinical benefit and rates of survivorship at minimum 2-year follow-up ranging from 93.5% to 100%. LEVEL OF EVIDENCE: Level IV: systematic review of level III to IV studies.
