Matt Homer, Godfrey Pell, Richard Fuller
INTRODUCTION: Many standard setting procedures focus on the performance of the "borderline" group, defined through expert judgments by assessors. In performance assessments such as Objective Structured Clinical Examinations (OSCEs), these judgments usually apply at the station level. METHODS AND RESULTS: Using largely descriptive approaches, we analyze the assessment profile of OSCE candidates at the end of a five year undergraduate medical degree program to investigate the consistency of the borderline group across stations...

BACKGROUND: The Objective Structured Clinical Examination (OSCE) is increasingly used at medical schools to assess practical competencies. To compare the outcomes of students at different medical schools, we introduced standardized OSCE stations with identical checklists. METHODS: We investigated examiner bias at standardized OSCE stations for knee- and shoulder-joint examinations, which were implemented into the surgical OSCE at five different medical schools. The checklists for the assessment consisted of part A for knowledge and performance of the skill and part B for communication and interaction with the patient...

Transmission below the cable cut-off wavelength may be a concern in some systems, especially for an optical supervisory channel (OSC) operating below the signal transmission band in systems built with G.654 fiber. In this work, we constructed a cabled span of G.654-compliant fiber and measured the multipath interference (MPI) generated during propagation through the span at a range of wavelengths below the cable cut-offs of the constituent fibers. Measurements were made under a range of conditions including different splice losses and the presence or absence of higher order mode filters placed around the splices...

BACKGROUND: Practical skills are often assessed using Objective Structured Clinical Skill Exams (OSCE). Nevertheless, in Germany, interchange and agreement between different medical faculties or a general agreement on the minimum standard for passing is lacking. METHODS: We developed standardized OSCE-stations for assessing structured clinical examination of knee and shoulder joint with identical checklists and evaluation standards. These were implemented into the OSCE-course at five different medical faculties...

Incomplete resections and damage to critical structures increase morbidity and mortality of patients with cancer. Targeted intraoperative fluorescence imaging aids surgeons by providing real-time visualization of tumors and vital structures. This study evaluated the tumor-targeted zwitterionic near-infrared fluorescent peptide cRGD-ZW800-1 as tracer for intraoperative imaging of multiple cancer types. cRGD-ZW800-1 was validated in vitro on glioblastoma (U-87 MG) and colorectal (HT-29) cell lines. Subsequently, the tracer was tested in orthotopic mouse models with HT-29, breast (MCF-7), pancreatic (BxPC-3), and oral (OSC-19) tumors...

Since it was developed at McMaster University School of Medicine in 2002, multiple medical interviews (MMI) have become a popular and accepted method of assessing candidates applying for medical training. Unlike a traditional panel interview it resembles the objective structured clinical examination (OSCE) with numerous 8-10 min stations assessing different topics or scenarios pertinent to medical training and healthcare. This was the first year of implementing MMI at Brighton and Sussex Medical School and my first year of interviewing...

Small push-pull molecules attract much attention as prospective donor materials for organic solar cells (OSCs). By chemical engineering, it is possible to combine a number of attractive properties such as broad absorption, efficient charge separation, and vacuum and solution processabilities in a single molecule. Here we report the synthesis and early time photophysics of such a molecule, TPA-2T-DCV-Me, based on the triphenylamine (TPA) donor core and dicyanovinyl (DCV) acceptor end group connected by a thiophene bridge...

In this work, we synthesized internal standards for four garlic organosulfur compounds (OSCs) by reductive amination with (13)C, D2-formaldehyde, and developed an isotope dilution analysis method to quantitate these organosulfur components in garlic samples. Internal standards were synthesized for internal absolute quantification of S-allylcysteine (SAC), S-allylcysteine sulfoxide (alliin), S-methylcysteine (SMC), and S-ethylcysteine (SEC). We used a multiple reaction monitoring (MRM) to detect (13)C, D2-formaldehyde-modified OSCs by ultrahigh-performance liquid phase chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) and obtained MS spectra showing different ratios of (13)C, D2-formaldehyde-modified and H2-formaldehyde-modified compounds...

BACKGROUND: Each year 700,000 infants die due to intrapartum-related complications. Implementation of Helping Babies Breathe (HBB)-a simplified neonatal resuscitation protocol in low-resource clinical settings has shown to reduce intrapartum stillbirths and first-day neonatal mortality. However, there is a lack of evidence on the effect of different HBB implementation strategies to improve and sustain the clinical competency of health workers on bag-and-mask ventilation. This study was conducted to evaluate the impact of multi-faceted implementation strategy for HBB, as a quality improvement cycle (HBB-QIC), on the retention of neonatal resuscitation skills in a tertiary hospital of Nepal...

Perovskite solar cells (PSCs) and organic solar cells (OSCs) are promising renewable light-harvesting technologies with high performance, but the utilization of hazardous dopants and high boiling additives is harmful to all forms of life and the environment. Herein, new multirole π-conjugated polymers (P1-P3) are developed via a rational design approach through theoretical hindsight, further successfully subjecting them into dopant-free PSCs as hole-transporting materials and additive-free OSCs as photoactive donors, respectively...

Organic solar cells (OSCs) usually need to be optimized with the strategies of thermal annealing (TA), solvent vapor annealing (SVA), or processing additives (PA) to obtain the best performance. Here, PA and TA were used simultaneously for OSCs based on the novel organic molecules TBDT-T6ffBT and OBDT-T6ffBT. The synergistic effect of PA and TA on the active-layer morphologies was investigated by measurements of optical microscopy, atomic force microscopy, transmission electron microscopy, and grazing incident X-ray diffraction...

For many decades, the dogma prevailed that female mammals had a finite pool of oocytes at birth and this was gradually exhausted during a lifetime of reproductive function. However, in 2004, a new era began in the field of female oogenesis. A study was published that appeared to detect oocyte-stem cells capable of generating new eggs within mouse ovaries. This study was highly controversial and the years since this initial finding have produced extensive research and even more extensive debate into their possibility...

In this work, we studied the performance enhancement of organic thin-film solar cells (OSCs) originating from the presence of diffraction gratings on the surface of the active layer. Two types of diffraction gratings, periodic gratings (Blu-ray disc recordable: BD-R) and quasi-random gratings (Blu-ray disc: BD), were employed as master templates for grating structures. The grating structures were introduced to the surfaces of poly(3-hexylthiophene) (P3HT):phenyl-C61-butyric acid methyl ester (PCBM) films, which were the active layers of the solar cells...
