The Script Concordance Test is a suitable test for assessing clinical reasoning in postgraduate medical education. We present the first nationwide, realtime, web-based experience of a Script Concordance Test administered to 3rd year pediatric residents. The test was administered to 268 residents (postgraduate year 3), from 56 different programs, requiring 46.1 ± 27.1 minutes to complete it, and scoring 65.3 ± 7.47 points. A later survey showed limited satisfaction from participants. This experience showed that this kind of test is feasible in this setting...

Paediatric palliative care (PPC) endeavours to alleviate the suffering and improve the quality of life of children with serious illnesses and their families. In the past two decades since WHO defined PPC and called for its inclusion in paediatric oncology care, rigorous investigation has provided important insights. For example, the first decade of research focused on end-of-life experiences of the child and the family, underscoring the high prevalence of symptom burden, the barriers to parent-provider concordance with regards to prognosis, as well as the need for bereavement supports...

Congenital heart disease (CHD) is a genetically heterogeneous disease. Targeted next-generation sequencing (NGS) offers a unique opportunity to sequence multiple genes at lower cost and effort compared to Sanger sequencing. We tested a targeted NGS of a specific gene panel in a relatively large population of non-syndromic CHD patients. The patient cohort comprised 68 CHD patients (45 males; 8.3 ± 1.7 years). Amplicon libraries for 16 CHD-strictly related genes were generated using a TruSeq® Custom Amplicon kit (Illumina, CA) and sequenced using the Illumina MiSeq platform...

There is no simple method to measure glomerular filtration rate (GFR) in swine, an established model for studying renal disease. We developed a protocol to measure GFR in conscious swine by using the plasma clearance of iohexol. We used two groups, test and validation, with eight animals each. Ten milliliters of iohexol (6.47 g) was injected into the marginal auricular vein and blood samples (3 mL) were collected from the orbital sinus at different points after injection. GFR was determined using two models: two-compartment (CL2: all samples) and one-compartment (CL1: the last six samples)...

BACKGROUND: Cerebral oximetry using near-infrared spectroscopy is a noninvasive optical technology to detect cerebral hypoxia-ischemia and develop interventions to prevent and ameliorate hypoxic brain injury. Cerebral oximeters are calibrated and validated by comparison of the near-infrared spectroscopy-measured cerebral O2 saturation (SctO2) to a "field" or reference O2 saturation (REF CX) calculated as a weighted average from arterial and jugular bulb oxygen saturations. In this study, we calibrated and validated the second-generation, 5 wavelength, FORE-SIGHT Elite with the medium sensor (source-detector separation 12 and 40 mm) for measurement of SctO2 in children with congenital heart disease...

Plasmodium ovale curtisi (Poc) and Plasmodium ovale wallikeri (Pow) have been described as two distinct species, only distinguishable by molecular methods such as PCR. Because of no well-defined endemic area and a variable clinical presentation as higher thrombocytopenia and nausea associated with Pow infection and asymptomatic forms of the pathology with Poc infection, rapid and specific identification of Plasmodium ovale curtisi and Plasmodium ovale wallikeri are needed. The aim of the study was to evaluate a new quantitative real-time PCR coupled with high resolution melting revelation (qPCR-HRM) for identification of both species...

BACKGROUND: A script concordance test (SCT) is a modality for assessing clinical reasoning. Concerns had been raised about the plausible validity threat to SCT scores if students deliberately avoided the extreme answer options to obtain higher scores. The aims of the study were firstly to investigate whether students' avoidance of the extreme answer options could result in higher scores, and secondly to determine whether a 'balanced approach' by careful construction of SCT items (to include extreme as well as median options as model responses) would improve the validity of an SCT...
