Purpose To compile and analyze structural and clinical outcomes after meniscus root tear treatment as currently described in the literature. Methods A review was conducted to identify studies published since 2011 on efficacy of repair, meniscectomy, and nonoperative management in the treatment of meniscus root tears. Patient cohorts were grouped into treatment categories, with medial and lateral root tears analyzed separately; data were collected on patient demographics, structural outcomes including joint space width, degree of medial meniscal extrusion, progression to total knee arthroplasty, and patient‐reported outcome measures. Risk of bias was assessed using the MINORS (methodological index for non‐randomized studies) criteria. Heterogeneity was measured using the I‐statistic, and outcomes were summarized using forest plots without pooled means. Results The 56 included studies comprised a total of 3,191 patients. Mean age among the included studies ranged from 24.6 to 65.6 years, whereas mean follow‐up ranged from 12 to 125.9 months. Heterogeneity analysis identified significant differences between studies. Change in joint space width ranged from –2.4 to –0.6 mm (i.e., decreased space) after meniscectomy (n = 186) and –0.9 to –0.1 mm after root repair (n = 209); change in medial meniscal extrusion ranged from –0.6 to 6.5 mm after root repair (n = 521) and 0.2 to 4.2 mm after meniscectomy (n = 66); and event rate for total knee arthroplasty ranged from 0.00 to 0.22 after root repair (n = 205), 0.35 to 0.60 after meniscectomy (n = 53), and 0.27 to 0.35 after nonoperative treatment (n = 93). Root repair produced the greatest numerical increase in International Knee Documentation Committee and Lysholm scores of the 3 treatment arms. In addition, root repair improvements in Knee Injury and Osteoarthritis Outcome Score Pain (range: 22‐32), Sports and Recreational Activities (range: 23‐36), Quality of Life (range: 22‐42), and Symptoms subscales (range: 10‐19), in studies with low risk of bias. Conclusions The literature reporting on the treatment of meniscus root tears is heterogenous and largely limited to Level III and IV studies. Current evidence suggests root repair may be the most effective treatment strategy in lessening joint space narrowing of the knee and producing improvements in patient‐reported outcomes. Level of Evidence Level IV, systematic review of Level II‐IV studies.

Background: The Spinal Cord Shape Classification System (SCSCS) class has been associated with spinal cord monitoring data loss during spinal deformity surgery. The objective of the current study was to prospectively validate the SCSCS as a predictor of spinal cord monitoring data loss during spinal deformity surgery. Methods: A prospective cohort study of consecutive patients who were undergoing primary deformity surgery at a single institution from 2018 to 2023 and whose major curve was in the spinal cord region was undertaken. Spinal cord morphology at the apex of the major curve on preoperative axial T2-weighted magnetic resonance imaging was used to categorize patients into 3 spinal cord shape types based on the SCSCS. The primary outcome was intraoperative neuromonitoring (IONM) data loss related to spinal cord dysfunction. Demographics and surgical and radiographic variables were compared between patients with IONM data loss and those without loss. Predictors of IONM loss were determined using bivariate and multivariable logistic regression analyses. Results: A total of 256 patients (168 adult, 88 pediatric) were included and were separated into 3 SCSCS types: 110 (43.0%) with Type I, 105 (41.0%) with Type II, and 41 (16.0%) with Type III. IONM loss was observed in 30 (11.7%) of the 256 patients, including 7 (6.4%) of 110 with SCSCS Type I, 7 (6.7%) of 105 with Type II, and 16 (39.0%) of 41 with Type III. IONM loss was associated with SCSCS Type III, the preoperative deformity angular ratio, performance of 3-column osteotomies, greater operative time, greater transfusion volume, and greater postoperative sagittal corrections. SCSCS type was the strongest independent predictor of IONM data loss. SCSCS Type III had the greatest odds of IONM loss (odds ratio [OR] = 6.68, 95% confidence interval [CI] = 2.45 to 18.23 compared with Types I and II combined). The overall predictive performance with respect to IONM loss (area under the receiver operating characteristic curve = 0.827) was considered excellent. Conclusions: This prospective cohort study of patients undergoing spinal deformity correction confirmed that patients with a Type-III spinal cord shape had greater odds of IONM loss. Inclusion of the SCSCS in preoperative risk stratification and intraoperative management of spinal deformity corrective surgery is recommended. Level of Evidence: Prognostic Level II .

AbstractBackgroundEmpirical evidence regarding the development of sensory responsivity in young children at high likelihood to develop autism spectrum disorder (ASD) remains relatively limited. It is unclear how sensory responsivity behaviors may change over time and impact later developmental outcomes. The goals of this study were to (a) characterize developmental trajectories of sensory responsivity across infancy (∼12 months), toddlerhood (∼24 months), and school age (6–11 years) in children at high and low familial likelihood for ASD; and (b) determine if sensory responsivity in infancy predicts adaptive and cognitive functioning at school age among children with ASD.MethodsGeneralized linear mixed effects models were used to examine scores from the Sensory Experiences Questionnaire in three groups of children including high‐likelihood children later diagnosed with ASD (HL‐ASD; n = 30), high‐likelihood children without ASD (HL‐Neg; n = 150), and low‐likelihood control children not meeting ASD diagnostic criteria (LL‐Neg; n = 94). Hierarchical linear regression was then used to examine the association between sensory responsivity scores in infancy and functional adaptive and cognitive outcomes at school age for children at high likelihood of ASD.ResultsDevelopment of sensory responsivity from infancy to later childhood is best estimated by the effects of chronological age and Group for Sensory Seeking and Hypo responsivity and the additional effect of the interaction of Group and chronological age for Total and Hyper responsivity. Early elevated Hypo responsivity and Sensory Seeking scores are negatively associated with later adaptive behavior but not cognitive level.ConclusionOverall, higher degrees of Sensory Seeking and Hypo sensory responsivity are detectable in autistic children's behavioral repertoires by 12 months of age and associate with reduced adaptive functioning in middle childhood. These results point to the potential importance of early detection and treatment implications of early sensory behaviors.

Summary Non‐steroidal anti‐inflammatory drugs (NSAIDs) are one of the mainstays of multimodal pain management. While effective for acute pain control, recent pre‐clinical evidence has raised concerns regarding an association between NSAIDs and chronic pain and potential opioid use. Our objective was to explore the association between peri‐operative use of prescription NSAIDs and the need for continued opioid prescriptions lasting 90–180 days in previously opioid‐naïve patients undergoing total knee arthroplasty. A database of health claims in the USA was used to identify all opioid‐naïve adult patients who underwent primary knee arthroplasty between January 2010 and October 2021. We evaluated the magnitude of association between peri‐operative prescription NSAID claims and claims for opioids at 90 days postoperatively using multivariable logistic regression models. Secondary outcomes included: the magnitude of association between peri‐operative NSAID prescription and claims for opioids at 180 days postoperatively; and identifying other potential factors associated with opioid claims at 90 days postoperatively. After risk adjustment using multivariable logistic regression models in the 789,736‐patient cohort, the adjusted odds ratio (95%CI) for a continuous claim of opioids at 90 and 180 days postoperatively among patients with a peri‐operative NSAID prescription within 30 days was 1.32 (1.30–1.35), p < 0.001; and 1.12 (1.10–1.15), p < 0.001, respectively. This estimate of effect remained robust at 90 days after accounting for known potential confounders, including pre‐existing knee pain and acute postoperative pain severity. Similar analysis of other pain medications (e.g. paracetamol) did not detect such an association. This population‐based cohort study suggests that peri‐operative prescription NSAID use may be associated with continued opioid prescription claims at 90 and 180 days after knee arthroplasty, even after adjusting for other observed covariates for continuous opioid claims. These novel findings can inform clinical decision‐making for post‐surgical pain management, risk–benefit discussions with patients and future research.

The accurate interpretation of CRRT machine alarms is crucial in the intensive care setting. ChatGPT, with its advanced natural language processing capabilities, has emerged as a tool that is evolving and advancing in its ability to assist with healthcare information. This study is designed to evaluate the accuracy of the ChatGPT-3.5 and ChatGPT-4 models in addressing queries related to CRRT alarm troubleshooting. This study consisted of two rounds of ChatGPT-3.5 and ChatGPT-4 responses to address 50 CRRT machine alarm questions that were carefully selected by two nephrologists in intensive care. Accuracy was determined by comparing the model responses to predetermined answer keys provided by critical care nephrologists, and consistency was determined by comparing outcomes across the two rounds. The accuracy rate of ChatGPT-3.5 was 86% and 84%, while the accuracy rate of ChatGPT-4 was 90% and 94% in the first and second rounds, respectively. The agreement between the first and second rounds of ChatGPT-3.5 was 84% with a Kappa statistic of 0.78, while the agreement of ChatGPT-4 was 92% with a Kappa statistic of 0.88. Although ChatGPT-4 tended to provide more accurate and consistent responses than ChatGPT-3.5, there was no statistically significant difference between the accuracy and agreement rate between ChatGPT-3.5 and -4. ChatGPT-4 had higher accuracy and consistency but did not achieve statistical significance. While these findings are encouraging, there is still potential for further development to achieve even greater reliability. This advancement is essential for ensuring the highest-quality patient care and safety standards in managing CRRT machine-related issues.

Background. Anesthesiologists frequently use intraoperative transesophageal echocardiography (TEE) to aid in the diagnosis and management of hemodynamic problems during liver transplantation (LT). Although the use of TEE in US centers continues to increase, data regarding international use are lacking. Methods. This prospective, global, survey-based study evaluates international experience with TEE for LT. Responses from 252 LT (105 US and 147 non-US) centers representing 1789 anesthesiologists were analyzed. Results. Routine use of TEE in the United States has increased in the last 5 y (from 37% to 47%), but only 21% of non-US LT anesthesiologists use TEE routinely. Lack of training (44% US versus 70% non-US) and equipment (9% non-US versus 34% US) were cited as obstacles. Most survey participants preferred not to perform a complete cardiac examination but rather use only 6 of 11 basic views. Although non-US LT anesthesiologists more frequently had additional clinical training than their US counterparts, they had less TEE experience (13% versus 44%) and less frequently, TEE certification (22% versus 35%). Most LT anesthesiologists agreed that TEE certification is essential for proficiency. Of all respondents, 89% agreed or strongly agreed that TEE provides valuable information needed for immediate clinical decision-making, and >86% agreed or strongly agreed that that information could not be derived from other sources. Conclusions. The use of TEE for LT surgery in the US LT centers is currently higher compared with non-US LT centers. This may become a standard monitoring modality during LT in the near future.

Background. Portopulmonary hypertension (PoPH) occurs in patients with advanced liver disease and can be a contraindication to liver transplant (LT). Improvement of hemodynamic parameters with pulmonary arterial hypertension (PAH) therapies (including endothelin receptor antagonists [ERAs]) may help some patients to become eligible for LT. Methods. We conducted a retrospective secondary data analysis to describe the clinical course and management of PoPH in patients on a US registry LT waitlist and outcomes in patients receiving an ERA. Results. At the time of LT waitlist entry (1996–2019), patient characteristics and disease severity were similar in the 685 patients with PoPH enrolled overall (LT waitlist data set) and the 420 of them who underwent LT (LT data set). Most patients (92.0%) had a model for end-stage liver disease exception granted before entering the LT waitlist. Patients spent a median of 8.9 mo (interquartile range, 3.7–19.7) on the LT waitlist before undergoing LT. Overall, 77.1% of patients received PAH treatment at LT waitlist entry (ERAs, 30.1%). Hemodynamic parameters improved in ≥95% of patients between the first assessment versus the second (median interval, 9 mo) and last assessments (median interval, 14 mo). At the first assessment, 49.6% of patients had mean pulmonary arterial pressure ≥45 mm Hg versus 2.6% and 1.8% of patients at the second and last assessments, respectively; 47.5% of patients had pulmonary vascular resistance >450 dynes·s/cm5 versus 0.9% and 0.2% of patients at the second and last assessments. One-year survival was 90.6% (95% confidence interval [CI], 87.6-92.9) following LT waitlist entry and was 86.4% (95% CI, 82.6-89.5) after LT; 5-y survival was 67.4% (95% CI, 60.0-73.8) while on the LT waitlist (before LT) and was 75.6% (95% CI, 70.4-80.0) following LT. Conclusions. This large US study of patients with PoPH on an LT waitlist confirms that effective PAH treatments can help patients achieve acceptable hemodynamics, providing the opportunity to undergo LT.
