As the prevalence of hip osteoarthritis increases, the number of total hip arthroplasty (THA) procedures performed is also projected to increase. Accurately risk-stratifying patients who undergo THA would be of great utility, given the significant cost and morbidity associated with developing perioperative complications. We aim to develop a novel machine learning (ML)-based ensemble algorithm for the prediction of major complications after THA, as well as compare its performance against standard benchmark ML methods.

This is a retrospective cohort study of 89,986 adults who underwent primary THA at any California-licensed hospital between 2015 and 2017. The primary outcome was major complications (eg infection, venous thromboembolism, cardiac complication, pulmonary complication). We developed a model predicting complication risk using AutoPrognosis, an automated ML framework that configures the optimally performing ensemble of ML-based prognostic models. We compared our model with logistic regression andd to logistic regression and other standard ML benchmark algorithms. By providing accurate prognostic information, this algorithm may facilitate more informed preoperative shared decision-making.
Family caregiver burden among older adults with advanced cancer remains poorly understood. We sought to (1) identify patient factors associated with caregiver burden and (2) examine how amount of time caregiving modifies these relationships.

Cross-sectional analysis of baseline data from a cluster-randomized palliative care intervention trial including patients with advanced cancer and their family caregivers, recruited from 17 oncology practices in Pennsylvania. Caregiver burden was measured using Zarit Burden Interview (ZBI-12; range 0-48). Patient factors included functional status (Eastern Cooperative Oncology Group), symptom burden (Edmonton Symptom Assessment Scale), anxiety and depression (Hospital Anxiety and Depression Scale), and quality of life (Functional Assessment of Chronic Illness Therapy - Palliative Care). Using adjusted multivariable regression, we analyzed (1) independent associations between patient factors and caregiver burden and (2) how weekly caregiving hours modified these relationships.

Among 441 patient-caregiver dyads, mean patient age was 70±10 and caregiver age was 62±13years. Most caregivers (59%) were patients' partners. Caregivers reported 44.5±53.5 average hours spent caregiving weekly; mean ZBI-12 scores were 10.3±7.3. Worse patient functional status (β=4.20, p<0.01), poorer quality of life (β=-0.07, p<0.01), more anxiety (β=0.33, p<0.01) and depression (β=0.33, p<0.01) were associated with higher caregiver burden; caregiving hours did not affect these relationships.

In advanced cancer, poor patient physical and mental health is associated with higher caregiver burden regardless of hours caregiving; future studies should examine interventions tailored to alleviate caregiver burden for this group.

The main forms of ACT include tumor infiltrating lymphocytes (TILs), engineered T cell receptor (TCR) T cells, and chimeric antigen receptor (CAR) T cells. While ACT has had success in hematological malignancies, particularly in B cell lymphomas targeted with CAR T cells, these favorable outcomes have yet to be replicated in solid tumors. Appropriate solid tumor target antigens are difficult to identify for ACT. Trafficking to tumor sites and infiltrating solid tumor burdens remains a problem for ACT cells. Persistence of ACT cells, which is important in creating a durable response, is also a major challenge, partly attributed to the formidable microtumor environment conditions. The costly and time-intensive manufacturing process for ACT is also an obstacle to widespread adoption. In this review, we discuss the challenges of ACT therapy in the treatment of solid tumors and explore the ongoing efforts to improve this immunotherapy approach in non-hematological malignancies.
Hamstring injuries are common among soccer players. The hamstring outcome score (HaOS) might be useful to identify amateur players at risk of hamstring injury. Therefore the aims of this study were To determine the association between the HaOS and prior and new hamstring injuries in amateur soccer players, and to determine the prognostic value of the HaOS for identifying players with or without previous hamstring injuries at risk of future injury.

Cohort study.

HaOS scores and information about previous injuries were collected at baseline and new injuries were prospectively registered during a cluster-randomized controlled trial involving 400 amateur soccer players. Analysis of variance and t-tests were used to determine the association between the HaOS and previous and new hamstring injury, respectively. Logistic regression analysis indicated the prognostic value of the HaOS for predicting new hamstring injuries.

Analysis of data of 356 players indicated that lower HaOS scores were associated with more previous hamstring injuries (F=17.4; p=0.000) and that players with lower HaOS scores sustained more new hamstring injuries (T=3.59, df=67.23, p=0.001). selleck chemical With a conventional HaOS score cut-off of 80%, logistic regression models yielded a probability of hamstring injuries of 11%, 18%, and 28% for players with 0,1, or 2 hamstring injuries in the previous season, respectively.

The HaOS is associated with previous and future hamstring injury and might be a useful tool to provide players with insight into their risk of sustaining a new hamstring injury risk when used in combination with previous injuries.

Patients with Williams-Beuren syndrome are associated with a high risk of hemodynamic collapse during sedation and/or anesthesia, presumably due to occult coronary obstruction. The objective of this study was to determine the association between transthoracic echocardiogram findings and the presence of coronary obstruction to examine if coronary obstruction can be predicted by transthoracic echocardiogram before anesthesia.

Retrospective data analysis of patients with Williams-Beuren syndrome who underwent transthoracic echocardiogram, cardiac catheterization, and/or surgical interventions to determine the correlation between echocardiogram findings and the presence of coronary obstruction determined by cardiac catheterization and/or surgery.

Single-center university teaching hospital.

The study included 49 patients with Williams-Beuren syndrome who underwent transthoracic echocardiogram, cardiac catheterization, and/or surgical interventions.

The only variable associated with coronary artery obstruction was the maximum instantaneous gradient (MIG) across the left ventricular outflow tract (LVOT) on a transthoracic echocardiogram. LVOT MIG ≥ 75 mmHg as the optimal cutoff value was associated with coronary artery obstruction (area under the curve 0.659, odds ratio 6.71, 95% CI 1.31-34.35, p = 0.022).

LVOT gradient can serve as a good predictor of the presence of coronary obstruction in patients with Williams-Beuren syndrome.

This study investigated the incidence and risk factors of postoperative delirium (POD) after transcatheter aortic valve replacement (TAVR) and to evaluate the association between preoperative conditions, particularly frailty, and POD.

Observational, case-control study.

Single-center university hospital.

The study comprised 124 patients who underwent TAVR and were divided into the following two groups group D (patients diagnosed with POD) and group C (patients without POD).

None.

Twenty-seven patients (21.7%) developed POD (95% confidence interval 14.9%-30.1%). POD was defined as a diagnosis of delirium using the Confusion Assessment Method for Intensive Care Unit scale during the patients' intensive care unit stay. Preoperative and postoperative data of patient characteristics were obtained from their medical records. A multivariate logistic regression analysis was performed using variables associated with POD incidence. Frailty scores were significantly higher in group D than in group C. The distance covered in the six-minute walk test (6MD) was significantly shorter in group D than in group C. The risk of developing POD was significantly higher in patients with a 6MD shorter than 220 m. Multivariate logistic regression analysis showed that a shorter 6MD was an independent risk factor for POD (odds ratio 5.66; p = 0.004).

In the present study, POD was seen in 21.7% of the patients who underwent TAVR. A 6MD shorter than 220 m was an independent preoperative risk factor for POD. For patients at high risk of POD, more careful management in the perioperative period may reduce POD.

To evaluate the association of postoperative hemoglobin values and mortality in patients undergoing double- lung transplantation with intraoperative transfusion.

Retrospective cohort study.

University hospital.

Adult patients who underwent double-lung transplantation at the authors' institution, with intraoperative transfusion of packed red blood cells between 2009 and 2015.

None.

Intraoperative transfusion requirements and general characteristics of 554 patients were collected. A generalized additive model, controlling for postoperative hemoglobin levels, number of transfused units of packed red blood cells, perioperative change in hemoglobin levels, disease leading to lung transplantation, and postoperative extracorporeal membrane oxygenation, was created to predict one-year mortality. A postoperative hemoglobin level of 11.3 g/dL was calculated as an optimal cutoff point. The patients were stratified according to this level. The end -point was all-cause one-year mortality after double-lung transplantation, assessed using the Kaplan-Meier analysis with log-rank test. All-cause mortality of the 554 patients was 17%. Postoperatively, 171 patients (31%) were categorized as being below the cutoff point. Improved survival was observed in the group with higher postoperative hemoglobin values (p = 0.002).

Lower postoperative hemoglobin levels in double-lung transplantation recipients were associated with increased mortality during the first year after surgery. Confirmation of these findings in additional investigations could alter patient blood management for double-lung transplantation.
