BACKGROUND: Allografts donated after cardiac death (DCD) are the fastest growing organ source worldwide. Unfortunately, information is lacking on how to judge these organs' viability. Here, we analyzed the effects of donor characteristics, including age and BMI, on outcomes of DCD simultaneous-pancreas-kidney transplantation (SPK). METHODS: We evaluated UNOS DCD-SPK transplants from 1988 to 2012. Effects of donor characteristics on graft and recipient survival were evaluated using Cox Regression and the Kaplan-Meier method, and compared to predictions from the pancreas and kidney donor risk indices (PDRI, KDRI)...

BACKGROUND: Administration of adjuvant therapy (AT) in patients with intrahepatic cholangiocarcinoma (ICC) remains inconsistent despite recent trial data. This study investigates predictors of receipt of AT and survival. METHODS: Patients with ICC who underwent resection were identified using the NCDB (2004-2014). Logistic regression and Cox analysis were used to determine predictors of AT and survival, respectively. "High-risk" was defined as positive margins/nodes or stage III/IVa disease...

BACKGROUND: Outcomes of emergency general surgery (EGS) procedures on hematopoietic stem cell transplant (HST) recipients have not been defined in a large, national database. Whether EGS during HST engraftment admission, or in HST patients with graft versus host disease (GVHD) results in worse outcomes is unknown. METHODS: The National Inpatient Sample (NIS) was examined for patients with a history of BMT between 2001 and 2014. RESULTS: There were 520,000 HST admissions meeting inclusion criteria, of which, 14,143 (2...

BACKGROUND: Purported benefits of minimally-invasive inguinal hernia repair techniques include less postoperative pain, but objective data is lacking. We analyzed prescribing habits and opiate requirements to provide an objective comparison. METHODOLOGY: Inguinal hernia repairs performed on patients aged 18-65 from October 2016 through February 2018 were examined. Patients with prior opiate use or complicated operative courses were excluded. Discharge prescriptions, morphine milligram equivalents(MME), and additional prescriptions within three months were evaluated...

BACKGROUND: Aim of the study was to describe characteristics and outcomes of Hartmann's procedure (HP) and subsequent intestinal restoration. METHODS: Retrospective study including all patients who underwent HP over a period of 16 consecutive years. We propose a classification and regression tree for a more accurate view of the relationship between the variables related to intestinal restoration and their weighting in the decision to reverse HP. RESULTS: 533 patients were included...

BACKGROUND: Attenuating post-injury neuroendocrine stress abrogates persistent injury-associated anemia. Our objective was to examine the mechanisms by which propranolol and clonidine modulate this process. We hypothesized that propranolol and clonidine would decrease bone marrow expression of high-mobility group box-1 (HMGB1) and increase expression of stem cell factor (SCF) and B-cell lymphoma-extra large (Bcl-xL). METHODS: Male Sprague-Dawley rats were allocated to naïve control, lung contusion followed by hemorrhagic shock (LCHS), or LCHS plus daily chronic restraint stress (LCHS/CS) ±propranolol, ±clonidine...

BACKGROUND: Using the military as a model for an equal-access, no-cost healthcare system, we sought to (1) describe screening breast MRI compliance rates and (2) identify patient-perceived barriers to screening. METHODS: In this retrospective cohort study of a prospectively maintained database at a tertiary level center, we compared compliance among women at ≥20% risk of developing breast cancer (Tyrer-Cuzick) and conducted structured phone interviews with women at ≥30% risk...

AbdCT for the evaluation of AAP in the ED in the US may be excessive and is potentially (although rarely) misleading and harmful. A selective policy of 'AbdUS first' combined with an observation unit and/or surgeon evaluation prior to AbdCT is preferred to a 'routine AbdCT' policy. Repeated AbdCTs for abdominal pain are not recommended because of cumulative radiation exposure. Standardized and complete history and physical examination, such as that originally designed for computer-aided diagnosis of AAP, along with select laboratory testing and higher utilization of AbdUS lessens the necessity of AbdCT...

BACKGROUND: Evaluation of returns to the operating room (RORs) may spur practice modifications to improve patient outcomes and hospital practices. We determined the frequency and indications for RORs after breast operations. METHODS: We identified patients ≥18 years who underwent a breast operation at our institution 1/1/14-1/13/17 and assessed ROR within 45-days. RORs were categorized as unplanned/planned, staged/unstaged, or unrelated procedures. Univariate and multivariable analyses compared variables between patients who did and did not have an ROR...

The high rate of immunosuppressive medication non-adherence in transplant recipients demands the search for a solution that targets modifiable risk factors and incorporates mobile health technology to better engage and educate patients. Kidney transplant recipients (kidneys alone or multi-organ) were randomized to receive a mobile app known as Transplant Hero, both the app and a smart watch, or neither. The coefficient of variability (CV) of tacrolimus levels was measured at one and three months. No statistically significant differences in CV levels were observed between the three groups at either one or three months...

BACKGROUND: Lymphocele is a complication of sentinel node biopsy (SNB) for melanoma. Plant-based hemostatic powder (PBHP) may have a lymphostatic benefit. We studied whether PBHP placed intraoperatively could reduce lymphocele rates. METHODS: We performed an open label, prospective, IRB -approved, before- and-after, matched control trial of PBHP placed into the wound in patients undergoing SNB of groin or axillary nodes for melanoma staging. Patient/tumor features and lymphocele rates were compared by standard statistical tests...

BACKGROUND: Acute Kidney Injury (AKI) is associated with significant morbidity. The risk factors for AKI in elderly trauma patients have not been defined. METHODS: Injured patients 75 years old or older from 2014 to 2016 were evaluated. AKI was identified by RIFLE criteria. Patients with and without AKI were compared with chi square, ANOVA, and logistic regression. RESULTS: 836 patients were 75 years old or older. Patients with AKI were more commonly male, hypotensive on admission with a greater Injury Severity Score but age, diabetes, hypertension and baseline creatinine were similar...
