We present our experience for patients who have undergone an anatomic repair (AR) for congenitally corrected transposition of the great arteries (CCTGA) at the Children's Hospital of Wisconsin. A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male). Median age of anatomic repair was 15 months (range 4.5-45.6 months). Four patients had a bidirectional Glenn (BDG) prior to AR. At the time of AR,-9 (60%) underwent Senning/Rastelli procedure, 4 (26...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. GISTs express the receptor tyrosine kinase KIT, and the majority of GISTs present KIT gain-of-function mutations that cluster in the 5' end of the receptor juxtamembrane domain. On the other hand, little information is known about GISTs carrying mutations in the 3' end of the KIT juxtamembrane domain. Here we report and discuss a clinical case of localized duodenal GIST whose molecular characterization revealed the presence of a new 21 nucleotide/7 amino acid deletion in the 3' end of KIT juxtamembrane domain (Δ574-580)...

Alternative polyadenylation (APA) is increasingly recognized to regulate gene expression across different cell types, but obtaining APA maps from individual cell types typically requires prior purification, a stressful procedure that can itself alter cellular states. Here, we describe a new platform, cTag-PAPERCLIP, that generates APA profiles from single cell populations in intact tissues; cTag-PAPERCLIP requires no tissue dissociation and preserves transcripts in native states. Applying cTag-PAPERCLIP to profile four major cell types in the mouse brain revealed common APA preferences between excitatory and inhibitory neurons distinct from astrocytes and microglia, regulated in part by neuron-specific RNA-binding proteins NOVA2 and PTBP2...

BACKGROUND AND OBJECTIVES: Melasma is a common acquired, chronic hypermelanosis and still remains a therapeutic challenge. The low-fluence 1 064 nm Q-switched Nd:YAG laser is the most widely used for the treatment of moderate to severe melasma in Asia. Recently, the picosecond laser has been introduced for various pigmentary disorders such as melasma. We evaluated the efficacy and safety of a picosecond laser with dual-wavelengths (1 064 and 595 nm) and topical 2% hydroquinone (HQ) combination therapy on patients with melasma, and compared results with those obtained with 2% HQ alone...

INTRODUCTION: Laparoscopic total mesorectal excision is effective and safe but often technically challenging because of inadequate exposure. Transanal total mesorectal excision was introduced to mitigate this limitation and improve the quality of mesorectal dissection in even the most challenging cases. Currently, the technique for transanal total mesorectal excision dissection is not standardized. TECHNIQUE: The sequential approach to transanal total mesorectal excision mirrors the principles of the transanal abdominal transanal procedure...

Drawing on data from a survey of 1043 ex-combatants who took part in the civil war in Sierra Leone (1991-2002) this paper explores the conditions that predict a key outcome in the conflict literature: defection, or side-switching between the various organizations at war. This paper advances arguments drawn from the organizational ecology school and works to extend key theories related to "Blau Space" to the study of civil war. Using a series of logistic regression procedures, this paper tests various competing hypotheses against key contributions of the organizational ecology school...

Traditional in-house, laboratory-based medical imaging studies use hierarchical data structures (e.g., NFS file stores) or databases (e.g., COINS, XNAT) for storage and retrieval. The resulting performance from these approaches is, however, impeded by standard network switches since they can saturate network bandwidth during transfer from storage to processing nodes for even moderate-sized studies. To that end, a cloud-based "medical image processing-as-a-service" offers promise in utilizing the ecosystem of Apache Hadoop, which is a flexible framework providing distributed, scalable, fault tolerant storage and parallel computational modules, and HBase, which is a NoSQL database built atop Hadoop's distributed file system...

Routine outcome monitoring (rom) is becoming an integral part of many treatment procedures. In order to promote the use of rom in such procedures attention needs to focus more on the functions of rom than on implementation strategies.<br/> AIM: To clarify what functions rom must be able to perform for the clinician and client if it is to be used routinely.<br/> METHOD: We discuss the functions of rom as described in the literature.<br/> RESULTS: The fundamental role of rom is to signal that the client is not responding satisfactorily to treatment...

Training adult learners to use ultrasound in clinical practice relies on the ability of the learner to apply visuospatial concepts to the anatomy of the human body. We describe a visuospatial trainer that replicates the housing of an ultrasound transducer, through which a linear laser projects light in the same plane and orientation as the ultrasonic sound waves. We use this trainer in combination with a porcine heart dissection laboratory to teach bedside cardiac ultrasound and transthoracic echocardiography (TTE)...

A one-pot O-alkylation mediated macrocyclization approach has been used for the synthesis of carbohydrate-based macrocyclic azobenzene. The synthesized macrocycle can be reversibly isomerized between E and Z isomers upon UV or visible irradiation with excellent photostability and thermal stability (t1/2 = 51 days at 20°C for the Z isomer). A chirality transfer from the chiral sugar unit to azobenzene was observed by circular dichroism (CD). DFT and TD-DFT calculations were performed to calculate the optimal geometry and the theoretical absorption and CD spectra...

Until recently, waste management for national immunization programs was limited to sharps waste, empty vaccine vials, or vaccines that had expired or were no longer usable. However, because wild-type 2 poliovirus has been eradicated, the World Health Organization's (WHO's) Strategic Advisory Group of Experts on Immunization deemed that all countries must simultaneously cease use of the type 2 oral polio vaccine and recommended that all countries and territories using oral polio vaccine (OPV) "switch" from trivalent OPV (tOPV; types 1, 2, and 3 polioviruses) to bivalent OPV (bOPV; types 1 and 3 polioviruses) during a 2-week period in April 2016...

BACKGROUND: Screening for renal, hepatic and haematological disorders complicates the initiation of current first-line antiretroviral therapy (ART). Each additional test done adds substantial costs, both through direct laboratory expenses, but also by increasing the burden on health workers and patients. Evaluating the prevalence of clinically relevant abnormalities in different population groups could guide decisions about what tests to recommend in national guidelines, or in local adaptations of these...

James S MacDonall
Some have reported changing the schedule at one alternative of a concurrent schedule changed responding at the other alternative (Catania, 1969), which seems odd because no contingencies were changed there. When concurrent schedules are programmed using two schedules, one associated with each alternative that operate continuously, changing the schedule at one alternative also changes the switch schedule at the other alternative. Thus, changes in responding at the constant alternative could be due to the change in the switch schedule...
