AbstractObjectiveGiven that weight gain patterns in adolescents receiving outpatient Family‐Based Treatment (FBT) have not been characterized, the purpose of this study was to examine trajectories of weight gain in a group of adolescent patients with a restrictive eating disorder [e.g., anorexia nervosa (AN) and atypical AN] receiving FBT. This study also examined the association of patient characteristics with weight gain trajectories, including age, diagnosis, weight suppression, presenting BMI‐for‐age percentile, and eating pathology.MethodLatent growth mixture modeling was used to identify distinct weight trajectories, as defined by change in BMI‐for‐age percentile, for 153 adolescents with AN or atypical AN, receiving FBT.ResultsThere were five distinct weight gain trajectory profiles for adolescents receiving FBT for a restrictive eating disorder. Younger age and greater weight suppression were associated with more rapid weight gain trajectories. A pattern of slow and consistent weight gain was associated with older age and less eating pathology.DiscussionThere was considerable variability in weight gain trajectories in youth receiving outpatient FBT for a restrictive eating disorder. This suggests that patients' presenting information can be used to inform expectations regarding weight gain trajectories.

Background There are limited data on the role of temporary mechanical circulatory support ( MCS ) devices for cardiogenic shock before left ventricular assist device ( LVAD ) surgery. This study sought to evaluate the trends of use and outcomes of MCS in cardiogenic shock before LVAD surgery. Methods and Results This was a retrospective cohort study from 2005 to 2014 using the National Inpatient Sample (20% stratified sample of US hospitals). This study identified admissions undergoing LVAD surgery with preoperative cardiogenic shock. Admissions for other cardiac surgery and heart transplant were excluded. Temporary MCS was identified using administrative codes. The primary outcome was hospital mortality and secondary outcomes were hospital costs and lengths of stay in admissions with and without MCS use. In this 10‐year period, 9753 admissions were identified with 40.6% requiring pre‐ LVAD MCS . There was a temporal increase in the frequency of cardiogenic shock associated with an increase in non–intra‐aortic balloon pump MCS devices. The cohort receiving MCS had greater in‐hospital myocardial infarction, ventricular arrhythmias, and use of coronary angiography. On multivariable analysis, older age, myocardial infarction, and need for MCS devices were independently predictive of higher in‐hospital mortality. In 696 propensity‐matched pairs, use of MCS was predictive of higher in‐hospital mortality (odds ratio 1.4 [95% confidence interval 1.1–1.6]; P =0.02) and higher hospital costs, but similar lengths of stay. Conclusions In patients with cardiogenic shock bridged to LVAD therapy, there was a steady increase in preoperative MCS use. Use of MCS identified patients at higher risk for in‐hospital mortality and greater resource utilization.

Background: There are contrasting reports on the effectiveness of a concomitant intra-aortic balloon pump (IABP) in cardiogenic shock patients treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO). This study sought to compare short-term mortality in patients with cardiogenic shock treated with VA-ECMO with and without IABP. Methods and Results: We reviewed the published literature from 2000 to 2018 for studies evaluating adult patients requiring VA-ECMO for cardiogenic shock with concomitant IABP. Studies reporting short-term mortality were included. Meta-analysis of the association of IABP with mortality was performed using Mantel-Haenszel models. Subgroup analyses were performed in patients with cardiogenic shock complicating acute myocardial infarction (AMI) and postcardiotomy cardiogenic shock. Twenty-two observational studies with 4653 patients were included. These studies showed high heterogeneity for the total and postcardiotomy cardiogenic shock cohorts and low heterogeneity for the AMI cohort. Short-term mortality was not significantly different in patients with and without IABP 42.1% versus 57.8%; risk ratio, 0.80; 95% CI, 0.52–1.22; P =0.30. However, concomitant IABP with VA-ECMO was associated with lower mortality in patients with AMI (50.8% versus 62.4%; risk ratio, 0.56; 95% CI, 0.46–0.67; P <0.001). There was no difference in mortality in postcardiotomy cardiogenic shock and mixed causes for cardiogenic shock. Conclusions: In cardiogenic shock patients requiring VA-ECMO support, the use of IABP did not influence mortality in the total cohort. In patients with AMI, use of IABP with VA-ECMO was associated with 18.5% lower mortality in comparison to patients on VA-ECMO alone. Further randomized studies are warranted to corroborate these observational data.
