To compare perioperative outcomes in the three most common partial nephrectomy modalities: robotic (RPN), laparoscopic (LPN), and open (OPN), matched for nephrometry scores. Patients aged 16-85 who underwent RPN, LPN, or OPN from 2007 to 2014 for localized renal carcinoma within our healthcare system were enrolled. Age, sex, body mass index, and Charlson Comorbidity Index (CCI) as well as perioperative outcomes of estimated blood loss (EBL), length of hospital stay (LOS), ischemia time (IT), change in eGFR, positive margin rate, operative time (OT), and emergency room visit rates were compared between RPN, LPN, and OPN using the R...

The dissociation constant describes the interaction between two partners in the binding equilibrium and is a measure of their affinity. It is a crucial parameter to compare different ligands, e.g., competitive inhibitors, protein isoforms and mutants, for their binding strength to a binding partner. Dissociation constants are determined by plotting concentrations of bound versus free ligand as binding curves. In contrast, titration curves, in which a signal that is proportional to the concentration of bound ligand is plotted against the total concentration of added ligand, are much easier to record...

Background and Objectives: Many risk factors have been identified in minimally invasive cholecystectomies that lead to higher complications and conversion rates. No study that we encountered looked at nonvisualization of the gallbladder (GB) during surgery as a risk factor. We hypothesized that nonvisualization was associated with an increased risk of complications and could be an early intraoperative identifier of a higher risk procedure. Recognizing this could allow surgeons to be aware of potential risks and to be more likely to convert to open for the safety of the patient...

Effusion-based lymphoma (EBL) is a rare but distinct entity of large B-cell lymphoma in effusion without association with human herpes virus-8 (HHV-8). Spontaneous regression after pleurocentesis has been observed; but to our knowledge, there are no reports on the morphological and molecular features of subsequent aspirations in regressing cases. Here, we report the case of a 92-year-old male with chronic obstructive pulmonary disease, who presented with right pleural effusion. He had no human immunodeficiency virus, hepatitis B virus, or hepatitis C virus infection, and CT scans revealed no mass lesion...

Uterine fibroids are extremely common uterine neoplasms. However, whether robotic-assisted laparoscopic myomectomy (RALM) is superior to laparoscopic myomectomy (LM) or abdominal myomectomy (AM) is still debatable. Consequently, we aimed to compare the three currently major surgical techniques used in patients with uterine fibroids. We searched the PubMed, the Cochrane Library, MEDLINE, Embase, and Web of Science databases up to April 22, 2017. The meta-analysis included 20 studies involving 2852 patients. The number of complications [odd ratio (OR) 0...

OBJECTIVE: The aim of this study was to elucidate the impact of intraoperative blood loss on outcomes following pancreatoduodenectomy (PD). BACKGROUND: The negative impact of intraoperative blood loss on outcomes in PD has long been suspected but not well characterized, particularly those factors that may be within surgeons' control. METHODS: From 2001 to 2015, 5323 PDs were performed by 62 surgeons from 17 institutions. Estimated blood loss (EBL) was discretized (0 to 300, 301 to 750, 751 to 1300, and >1300 mL) using optimal scaling methodology...

OBJECTIVE: Despite the therapeutic and surgical interventions for the management of gastroesophageal reflux disease (GERD), yet the high cost and the post-operative complications had led to a significant socioeconomic burden. The aim was to evaluate the safety and efficacy of endoscopic band ligation (EBL) in the management of refractory GERD. METHODS: A total of 150 patients with refractory GERD were assigned to an EBL group (banding was done at four quadrants just at the gastroesophageal junction (GEJ) (n = 75) or to a control group (optimized dose of PPI, n = 75)...

In pediatric RT, donor allograft size often exceeds the expected recipient norms, especially in younger recipients. An "oversize" graft might not only present a technical- and space-related challenge, but may possibly lead to increased demands in perioperative volume requirements due to the disparity between donor and recipient in renal blood flow. We evaluated transfusion practices at a single tertiary institution with special consideration of kidney graft size, hypothesizing that oversize graft kidneys might lead to a quantifiable increased need of blood transfusion in smaller recipients...

Tissue samples from Australian carpet pythons (Morelia spilota) with neurological disease were screened for viruses using next-generation sequencing. Coding complete genomes of two bornaviruses were identified with the gene order 3'-N-X-P-G-M-L, representing a transposition of the G and M genes compared to other bornaviruses and most mononegaviruses. Use of these viruses to search available vertebrate genomes enabled recognition of further endogenous bornavirus-like elements (EBLs) in diverse placental mammals, including humans...
