Bone age assessment (BAA) is a commonly performed diagnostic study in pediatric radiology to assess skeletal maturity. The most commonly utilized method for assessment of BAA is the Greulich and Pyle method (Pediatr Radiol 46.9:1269-1274, 2016; Arch Dis Child 81.2:172-173, 1999) atlas. The evaluation of BAA can be a tedious and time-consuming process for the radiologist. As such, several computer-assisted detection/diagnosis (CAD) methods have been proposed for automation of BAA. Classical CAD tools have traditionally relied on hard-coded algorithmic features for BAA which suffer from a variety of drawbacks...

BACKGROUND: Benchmark dose (BMD) modeling is an important step in human health risk assessment and is used as the default approach to identify the point of departure for risk assessment. A probabilistic framework for dose-response assessment has been proposed and advocated by various institutions and organizations; therefore, a reliable tool is needed to provide distributional estimates for BMD and other important quantities in dose-response assessment. OBJECTIVES: We developed an online system for Bayesian BMD (BBMD) estimation and compared results from this software with U...

Continuous femoral nerve block (cFNB) is thought to increase the risk of falls after total knee arthroplasty (TKA). Previous studies have failed to consider the timing of cFNB removal in relation to inpatient falls. We investigated all inpatient falls after TKA over a 3-year period using our institutional safety report database. Ninety-five falls were reported from a total of 3745 patients. The frequency of falls after TKA persisted at a similar rate despite removal of cFNB and likely regression of femoral nerve block...

The statistical analysis of positron emission tomography (PET) standardized uptake value (SUV) measurements is challenging due to the skewed nature of SUV distributions. This limits utilization of powerful parametric statistical models for analyzing SUV measurements. An ad-hoc approach, which is frequently used in practice, is to blindly use a log transformation, which may or may not result in normal SUV distributions. This study sought to identify optimal transformations leading to normally distributed PET SUVs extracted from tumors and assess the effects of therapy on the optimal transformations...

INTRODUCTION: Perioperative programs aimed at decreasing surgical stress to colorectal patients can reduce hospital length of stay and morbidity while improving the patient’s perception of the surgical experience. Our goal was to transform patient care from a perioperative platform based on individual physician and nurse choice to a standardized evidence-based Enhanced Recovery After Surgery (ERAS) protocol for all patients undergoing elective colorectal resections. METHODS: An institutional review board-approved retrospective review was performed for the first 12 months of ERAS protocol-driven patient care in 2014 and compared to the prior 12 months (2013) of individual choice managed care...

PURPOSE OF REVIEW: We reviewed the strategies associated with hypoglycemia risk reduction among critically ill non-pregnant adult patients. RECENT FINDINGS: Hypoglycemia in the ICU has been associated with increased mortality in a number of studies. Insulin dosing and glucose monitoring rules, response to impending hypoglycemia, use of computerization, and attention to modifiable factors extrinsic to insulin algorithms may affect the risk for hypoglycemia. Recurring use of intravenous (IV) bolus doses of insulin in insulin-resistant cases may reduce reliance upon higher IV infusion rates...

The development of conventional, silicon-based computers has several limitations, including some related to the Heisenberg uncertainty principle and the von Neumann "bottleneck". Biomolecular computers based on DNA and proteins are largely free of these disadvantages and, along with quantum computers, are reasonable alternatives to their conventional counterparts in some applications. The idea of a DNA computer proposed by Ehud Shapiro's group at the Weizmann Institute of Science was developed using one restriction enzyme as hardware and DNA fragments (the transition molecules) as software and input/output signals...

OBJECTIVES: For healthcare systems of any size, it is important to minimize costs while maximizing outcomes. One idea of how to achieve these goals has been the reduction in hospital-related complications, including infection and surgical complications, among others. In the United States, policy makers recently adopted the 'Hospital Compare' program as a way to encourage consumers and improve hospitals. This article evaluates the effectiveness of this policy. STUDY DESIGN: This article uses an observed cohort study of most US hospitals across four different indices...

BACKGROUND: Intestinal transplantation (ITx) is the definitive therapy for patients suffering from intestinal failure. Previously published reports suggest that these cases should be managed perioperatively with the same intensive monitors and techniques as in liver transplantation. METHODS: We retrospectively reviewed the anesthetic management of 67 isolated intestinal, intestinal-pancreas, and intestinal-kidney transplants over the previous decade (2005-2015) in our tertiary care institution...

The type strain SUR2 of the novel species Chryseobacterium limigenitum was isolated from a dehydrated sludge of the municipal sewage treatment plant in Dogoše near Maribor in Slovenia. The draft genome, with 60 contigs, 4,697,725bp, 34.4% of G+C content, was obtained using the Illumina HiSeq 2500-1 platform. Joint Genome Institute Microbial Genome Annotation Pipeline (MGAP v.4) has identified 4322 protein-coding sequences including resistance genes against arsenic and other heavy metals. In addition, a subclass B3 metallo-β-lactamase, which confers resistance to penicillins, cephalosporins and carbapenems, was also present in the genome...

BACKGROUND: Metastatic melanoma of unknown primary (MUP) is uncommon, biologically ill defined, and clinically understudied. MUP outcomes are seldom reported in clinical trials. In this study, we analyze responses of MUP patients treated with systemic therapy in an attempt to inform treatment guidelines for this unique population. METHODS: New York University (NYU)'s prospective melanoma database was searched for MUP patients treated with systemic therapy. PubMed and Google Scholar were searched for MUP patients treated with immunotherapy or targeted therapy reported in the literature, and their response and survival data were compared to the MUP patient data from NYU...

OBJECTIVES: Intussusception is the most common abdominal emergency in pediatric patients aged 6 months to 3 years. There is often a delay in diagnosis, as the presentation can be confused for viral gastroenteritis. Given this scenario, we questioned the practice of performing emergency reductions in children during the night when minimal support staff are available. Pneumatic reduction is not a benign procedure, with the most significant risk being bowel perforation. We performed this analysis to determine whether it would be safe to delay reduction in these patients until normal working hours when more support staff are available...
