OBJECTIVE: Pharmaceutical treatment of latent tuberculosis infection (LTBI) reduces the risk of progression to active tuberculosis (TB); however, poor adherence tempers the protective effect. We aimed to estimate the health burden of non-adherence, the maximum allowable cost of hypothetical new adherence interventions to be cost-effective and the potential value of existing adherence interventions for patients with low-risk LTBI in Canada. DESIGN: A microsimulation model of LTBI progression over 25 years...

Abortion due to Toxoplasma gondii has been suspected in New Zealand farmed red deer. However, knowledge around the epidemiology and prevalence of T. gondii in farmed red deer is limited. The aim of this study was to firstly, assess the sensitivity and specificity of two commercially available assays, ELISA and latex agglutination test (LAT), for use in deer and secondly, to estimate the sero-prevalence of T. gondii in red deer. A total of 252 sera from rising 2-year-old and adult hinds from 17 New Zealand red deer herds at early and late pregnancy scanning and from known aborted and/or non-aborted hinds were tested for the presence of T...

Human islet amyloid polypeptide (hIAPP) is a natively unfolded polypeptide hormone of glucose metabolism, which is co-secreted with insulin by the β-cells of the pancreas. In patients with type 2 diabetes, IAPP forms amyloid fibrils because of diabetes-associated β-cells dysfunction and increasing fibrillation, in turn, lead to failure of secretory function of β-cells. This provides a target for the discovery of small organic molecules against protein aggregation diseases. However, the binding mechanism of these molecules with monomers, oligomers and fibrils to inhibit fibrillation is still an open question...

INTRODUCTION: With the increasing adoption of peroral endoscopic myotomy (POEM) as a first-line therapy for achalasia as well as a growing list of other indications, it is apparent that there is a need for effective training methods for both endoscopists in training and those already in practice. We present a hands-on-focused with pre- and post-testing methodology to teach these skills. METHODS: Six POEM courses were taught by 11 experienced POEM endoscopists at two independent simulation laboratories...

Killer cell immunoglobulin-like receptors (KIRs) are rapidly evolving species-specific natural killer (NK) cell receptors associated with protection against multiple different human viral infections. We report that the activating receptor KIR2DS2 directly recognizes viral peptides derived from conserved regions of flaviviral superfamily 2 RNA helicases in the context of major histocompatibility complex class I. We started by documenting that peptide LNPSVAATL from the hepatitis C virus (HCV) helicase binds HLA-C*0102, leading to NK cell activation through engagement of KIR2DS2...

We characterized the transcriptional response accompanying maintenance of long-term sensitization (LTS) memory in the pleural ganglia of Aplysia californica using microarray (N = 8) and qPCR (N = 11 additional samples). We found that 24 h after memory induction there is strong regulation of 1198 transcripts (748 up and 450 down) in a pattern that is almost completely distinct from what is observed during memory encoding (1 h after training). There is widespread up-regulation of transcripts related to all levels of protein production, from transcription (e...

CONTEXT: Older adults with advanced illness and associated symptoms may benefit from primary palliative care, but limited data exist to identify older adults in U.S. primary care to benefit from this care. OBJECTIVES: To describe U.S. primary care visits among adults 65 years and older with advanced illness. METHODS: Cross-sectional analysis of the National Ambulatory and Hospital Ambulatory Medical Care Surveys (2009-2011) was conducted using chi-square tests to compare visits without and with advanced illness to U...

PURPOSE: To describe and test a quantitative system for designating prostate tumor location on magnetic resonance imaging (MRI) and prostatectomy. A system for describing tumor location will facilitate research correlating MRI and pathology. MATERIALS AND METHODS: The prostate cylindrical coordinate (PCC) system was developed for locating prostate tumors using 3 coordinate values. The 3 coordinate values include the angular location centered on the urethra, the radial distance to the periphery and the long axis from apex to base...

A 59-year-old man developed massive hemoptysis, 1 month after undergoing cryoablation procedure for atrial fibrillation. He underwent emergent bronchoscopy that revealed massive, active bleeding with clots requiring repeated suctioning, epinephrine, and cold saline injection. The source of bleeding was identified in a follow-up bronchoscopy performed few days later-a 2×3 cm area of ulceration of the left main stem bronchus which was missed in the initial bronchoscopy owing to blood obscuring the field of vision...

The fundamental technique of performing percutaneous cardiovascular (CV) interventions has remained unchanged and requires operators to wear heavy lead aprons to minimize exposure to ionizing radiation. Robotic technology is now being utilized in interventional cardiology partially as a direct result of the increasing appreciation of the long-term occupational hazards of the field. This review was undertaken to report the clinical outcomes of percutaneous robotic coronary and peripheral vascular interventions...

The objective of this study was to measure internal medicine resident engagement with an electronic medical record-based dashboard providing feedback on their use of routine laboratory tests relative to service averages. From January 2016 to June 2016, residents were e-mailed a snapshot of their personalized dashboard, a link to the online dashboard, and text summarizing the resident and service utilization averages. We measured resident engagement using e-mail read-receipts and web-based tracking. We also conducted 3 hour-long focus groups with residents...

AIM: This study aims to determine and compare the extent of inhibition of demineralization and promotion of remineralization of permanent molar enamel with and without application of three remineralizing agents. MATERIALS AND METHODS: Forty extracted permanent molars were randomly divided into two groups 1 and 2, longitudinally sectioned into four and divided into subgroups A, B, C, and D. The sections were coated with nail varnish leaving a window of 3 mm × 3 mm...

Pembrolizumab and nivolumab are highly selective anti PD-1 antibodies approved for the treatment of advanced malignancies. Variable exposure and significant wastage have been associated with body size dosing of monoclonal antibodies. The following dosing strategies were evaluated using simulations: body weight, dose banding, fixed dose and pharmacokinetics based method. The relative cost to body weight dosing for band, fixed 150 mg and 200 mg, and pharmacokinetics derived strategies were -15%, -25%, +7% and -16% for pembrolizumab and -8%, -6%, and -10% for band, fixed, and pharmacokinetics derived strategies for nivolumab...

PURPOSE: The purpose of this study is to describe our technique for pericatheter retrograde urethrogram (pcRUG) and to evaluate the utility of a pcRUG to detect a clinically significant leak after urethral reconstruction. METHODS: We retrospectively reviewed our prospective IRB-approved database of patients undergoing urethral reconstruction. pcRUG was performed at 3-4 weeks after surgery, in standardized fashion. Patients were placed in oblique position, and with the penis stretched, diluted contrast was instilled via an angiocatheter alongside the indwelling urethral catheter under dynamic fluoroscopy...

INTRODUCTION: Percutaneous transluminal angioplasty (PTA), with or without stent placement, has become the treatment of choice for portal vein complications (PVC) following liver transplantation. We aimed to assess long-term outcomes of intervention in paediatric transplant recipients, in a single institution. MATERIALS AND METHODS: 227 children received 255 transplants between November 2000 and September 2016. 30 patients developed PVC of whom 21 had percutaneous intervention...
