INTRODUCTION The aim of this study was to evaluate the amount of root canal dentin removed and apical transportation occurrence after instrumentation of mesiobuccal canals of maxillary molars with ProTaper Next (PTN [Dentsply Maillefer, Ballaigues, Switzerland]), OneShape (OS [MicroMega, Besançon, France]), and EdgeFile (EF [Edge Endo, Albuquerque, NM]) rotary systems. METHODS Twenty-seven mesiobuccal canals of maxillary molars were used. Canals were randomly divided into 3 groups for canal preparation PTN, EF X3, or OS (n = 9 for each group). Micro-computed tomographic imaging was used to measure apical transportation (mm) and the volume of dentin removed (mm3). The amount of dentin removed was measured for the coronal portion and for the whole canal length. Superposition of pre- and postoperative cross-sectional apical slices were used to measure apical transportation at 1 mm from the apex; the differences were evaluated using the Kruskal-Wallis test and Wilcoxon analysis. The Spearman correlation coefficient was used to display the relationship between variables for each group. The significance level was set at P .05). The average amount of apical transportation for the PTN, OS, and EF X3 were 0.197, 0.263, and 0.218 mm, respectively. Statistically, there were no significant differences between the 3 rotary instruments for apical transportation. CONCLUSIONS The amount of dentin removed for the coronal third portion and the whole canal length was similar for the PTN, OS, and EF X3 rotary instruments. Although there were differences in the sizes of apical enlargement, no apical transportation was observed in any of the instrumentation systems. Optimal dose management of psychotropic drugs during the perinatal period reduces the risk for recurrence of mood episodes in women with Bipolar Disorder. Physiological changes during pregnancy are associated with decreases in the plasma concentrations of the majority of mood stabilizing medications. Regular symptom and drug concentration monitoring for lithium and anticonvulsants with reflexive dose adjustment improves the probability of sustained symptom remission across pregnancy. The elimination clearance trajectory across pregnancy for psychotropics dictates the frequency of laboratory monitoring and dose adjustment. The literature on the pharmacokinetics of lithium, lamotrigine, carbamazepine and atypical antipsychotics during pregnancy and postpartum are reviewed, recommendations for symptom and laboratory monitoring are proposed and recommendations for dose adjustments are presented. OBJECTIVE The goal of this study was to select branched endograft designs that could fit most aortic arch anatomies. Such off-the-shelf endografts, once available, would be an endovascular therapeutic option to consider in the acute setting and would shorten the design and manufacturing process. METHODS We retrospectively analyzed the endograft plans of all custom-made aortic arch branched endografts implanted between 2013 and early 2018 provided by the Cook Planning Center (EMEA Planning Services; Cook Medical, London, United Kingdom). Available data points of the endograft plans include proximal, intermediate, and distal endograft diameters; number of sealing stents; total length of the endograft; and number of branches. RESULTS There were 286 two-branch endografts analyzed. We divided the endografts in three groups according to their proximal diameters 34 mm, 36 mm, and 38 mm (group 1); 40 mm and 42 mm (group 2); and 44 mm and 46 mm (group 3). In group 1, 63% of the endografts had one proximal sealing stent, whereas in group 3, 63% had two proximal sealing stents. The distal diameters of the endografts ranged from 26 mm to 46 mm. The mean length was 236 mm (186-256 mm). A shorter standardized length of 211 mm was selected to anticipate distal extensions. According to our analysis, most group 1 patients could have been treated with a 38-mm proximal diameter and 30-mm distal diameter endograft with one sealing stent; most group 2 patients, with a 42-mm proximal diameter and 32-mm distal diameter endograft with both one and two proximal sealing stents; and most group 3 patients, with a 46-mm proximal diameter and 36-mm distal diameter endograft, also with both one and two proximal sealing stents. CONCLUSIONS Five standardized off-the-shelf endografts can cover a majority of aortic arch anatomies and offer an option for acute endovascular treatment of aortic arch disease. BACKGROUND Some clinical features of patients after stroke may be modifiable and used to predict outcomes. Identifying these features may allow for refining plans of care and informing estimates of posthospital service needs. The purpose of this study was to identify key factors that predict functional independence and living setting 3 months after rehabilitation hospital discharge by using a large comprehensive national data set of patients with stroke. METHODS The Uniform Data System for Medical Rehabilitation was queried for the records of patients with a diagnosis of stroke who were hospitalized for inpatient rehabilitation from 2005 through 2007. Selleckchem PRT543 The system includes demographic, administrative, and clinical variables collected at rehabilitation admission, discharge, and 3-month follow-up. Primary outcome measures were the Functional Independence Measure score and living setting 3 months after rehabilitation hospital discharge. RESULTS The sample included 16,346 patients (80% white; 50% women; mean [SD] age, 70.3 [13.1] years; 97% ischemic stroke). The strongest predictors of Functional Independence Measure score and living setting at 3 months were those same factors at rehabilitation discharge, despite considering multiple other predictor variables including age, lesion laterality, initial neurologic impairment, and stroke-related comorbid conditions. CONCLUSIONS These data can inform clinicians, patients with stroke, and their families about what to expect in the months after hospital discharge. The predictive power of these factors, however, was modest, indicating that other factors may influence postacute outcomes. Future predictive modeling may benefit from the inclusion of educational status, socioeconomic factors, and brain imaging to improve predictive power.
