Objective: Although adolescent-onset bipolar disorder is associated with significant morbidity, there have been few prospective outcome studies of this population. The aim study was to examine the 12-month adolescents following an initial hospitalization for a manic or mixed episode. Method: Bipolar (N=71) were recruited during their first episode and evaluated using diagnostic, symptomatic, functional assessments. Patients also at 1, 4, 8, 12 months after assess syndromic, outcomes....

In Brief Objective and Background: Morbidity, mortality, length of hospital stay after pancreaticoduodenectomy (PD) have significantly decreased over recent decades. Despite this progress, early readmission rates PD been reported as high 50%. Few reports delineated factors associated with PD. Methods: The medical records 6 high-volume institutions were reviewed for patients who underwent between 2005 2010. Data collection included patient characteristics, comorbidities, perioperative...

Previous research has identified a number of patient and operative factors associated with anastomotic leak after colectomy; however, study that examines these on national level direct coding for is lacking.The purpose this work was to identify risk quantify the additional morbidity mortality experienced by patients.We performed retrospective analysis patients who underwent segmental colectomy anastomosis from 2012 American College Surgeons National Surgical Quality Improvement Program...

Total pancreatectomy and islet cell autotransplantation (TPIAT) has been increasingly utilized for the management of chronic pancreatitis (CP) with early success. However, long-term durability this operation remains unclear.All patients undergoing TPIAT treatment CP 5-year or greater follow-up were identified inclusion in single-center observational study. End points included narcotic requirements, glycemic control, function, quality life (QOL), survival.Between 2000 2013, 166 underwent...

Morbid obesity is a barrier to renal transplantation and inadequately addressed by medical therapy. We present results of prospective evaluation laparoscopic sleeve gastrectomy (LSG) for patients failing achieve significant weight loss with Over 25-month period, 52 obese transplant candidates meeting NIH guidelines metabolic surgery underwent LSG. Mean age was 50.0 ± 10.0 years an average preoperative BMI 43.0 5.4 kg/m(2) (range 35.8-67.7 kg/m(2)). Follow-up after LSG 220 152 days 26-733...

Morbid obesity is a barrier to kidney transplant in patients with end-stage renal disease (ESRD). Laparoscopic sleeve gastrectomy (SG) an increasingly considered intervention, but the safety and long-term outcomes are uncertain. We reviewed prospectively collected data on ESRD chronic (CKD) undergoing SG from 2011 2018. There were 198 45 CKD (stages 1-4) who met National Institutes of Health guidelines for bariatric surgery underwent SG; 72% 48% achieved body mass index ≤ 40 35 kg/m2 ,...

Morbid obesity is a barrier to kidney transplantation due inferior outcomes, including higher rates of new-onset diabetes after (NODAT), delayed graft function (DGF), and failure. Laparoscopic sleeve gastrectomy (LSG) increases transplant eligibility by reducing BMI in candidates, but the effect surgical weight loss on posttransplantation outcomes unknown. Reviewing single-center medical records, we identified all patients who underwent LSG before from 2011-2016 (n = 20). Post-LSG recipients...

Background: Early pharmacologic treatment for blunt cerebrovascular injury (BCVI) is often withheld when concomitant traumatic brain or cervical spinal cord occurs. This study examines the safety and efficacy of early patients with both BCVI neurologic (TNI). Methods: Ten-year retrospective review a TNI was performed. Stroke outcomes those treated therapy their were compared not treated. In addition, likelihood worsening determined exposed to exposed. Multivariate logistic regression...

<h3>BACKGROUND:</h3> Prolonged mechanical ventilation, longer hospital stay, and a lower rate of home discharge have been reported with patient-ventilator asynchrony in medical patients. Though commonly encountered, is poorly defined within the traumatically injured population. <h3>METHODS:</h3> Mechanically ventilated trauma patients at an urban, level-1 center were enrolled. Breath waveforms recorded over 30 min first 48 hours following intubation. Asynchronous breaths as ineffective...

In patients with borderline resectable pancreas cancers, clinicians frequently consider radiographic response as the primary driver of whether should be offered surgical intervention following neoadjuvant therapy (NT). We sought to determine any correlation between and pathologic rates NT.Between 2005 2015, 38 at a tertiary care referral center underwent NT followed by pancreaticoduodenectomy for cancer. Radiographic after completion surgery were graded according RECIST Evans' criteria,...
