Lin Zhang, Ronald Rousseau, Gunnar Sivertsen
The scientific foundation for the criticism on the use of the Journal Impact Factor (JIF) in evaluations of individual researchers and their publications was laid between 1989 and 1997 in a series of articles by Per O. Seglen. His basic work has since influenced initiatives such as the San Francisco Declaration on Research Assessment (DORA), the Leiden Manifesto for research metrics, and The Metric Tide review on the role of metrics in research assessment and management. Seglen studied the publications of only 16 senior biomedical scientists...

Brandon Kikuo Richland, Christopher Ellstrom, Asim Ahmad, Daniel Jaffurs
BACKGROUND: Mandibular distraction osteogenesis is an important technique to correct the pediatric hypoplastic mandible. Regression of the mandible after distraction continues to be a challenge, with some studies reporting up to 22% to 56% decrease toward predistraction length in the first year. We hypothesize that a resorbable plate placed after removal of the distractor will provide additional stability to newly formed bone, allowing further time for consolidation and minimizing regression...

BACKGROUND: The United Kingdom (UK) lags behind other high-income countries in relation to technological innovation in healthcare. In order to inform UK strategy on how to catalyse innovation, we sought to understand what national strategies can help to promote a climate for innovation in healthcare settings by extracting lessons for the UK from international innovators. METHODS: We undertook a series of qualitative semi-structured interviews with senior international innovators from a range of health related policy, care/service delivery, commercial and academic backgrounds...

In the oil-rich Niger Delta, hydrocarbon pollution and oil spillages, gas flaring and sundry anthropogenic activities constitute sources of polycyclic aromatic hydrocarbons (PAHs), with food contamination playing a major role in human exposure. In this study we assessed PAH levels in wild and cultivated edible mushroom species consumed by the general population from the oil producing Niger Delta, Nigeria. The concentrations of USEPA-16 PAHs were determined by gas chromatography and carcinogenic and non-carcinogenic health risks were calculated...

Hard palate closure with a vomer flap at the time of lip repair has been widely adopted. A recent study by Deshpande et al. showed a high rate of failure of the vomer flap and led the authors to abandon the technique. We conducted a retrospective study of vomer flap healing in a consecutive series of cases performed by the senior author (D.O.). The case records of 71 patients who underwent repair of unilateral cleft lip and palate with a vomer flap at the time of lip repair were studied. Vomer flap healing was assessed and documented by the senior author at the time of definitive palate closure, and this was recorded...

BACKGROUND AND PURPOSE: Primary-progressive aphasia is a clinically and pathologically heterogeneous condition. Nonfluent, semantic, and logopenic are the currently recognized clinical variants. The recommendations for the classification of primary-progressive aphasia have advocated variant-specific patterns of atrophy. The aims of the present study were to evaluate the sensitivity and specificity of the proposed imaging criteria and to assess the intra- and interrater reporting agreements...

OBJECTIVES: The introduction of competency-based training has necessitated development and implementation of accompanying mechanisms for assessment. Procedure-based assessments (PBAs) are an example of workplace-based assessments that are used to examine focal competencies in the workplace. The primary objective was to understand surgical trainees' perspective on the value of PBA. DESIGN: Semistructured interviews with 10 surgical trainees individually interviewed to explore their views...

The numbers of women in medical school and in medical training have increased dramatically and are near 50% overall, but the number of women who advance to senior and leadership positions is not nearly this high. There are many reasons why the number of women in leadership roles in academic medicine has not kept pace with the number of women entering the field of medicine. Two popular themes are the glass ceiling (referring to an invisible barrier to advancement) and the leaky pipeline (the loss of women faculty along the path, or pipeline, to advancement)...

Recent books (Immunity. How Elie Metchnikoff changed the course of modern medicine and Expectations of Life) reviewed the important contribution of Metchnikoff to the emergence of gerontology as a new branch of biomedical sciences. Here, we insist on Metchnikoff's contribution and pivotal role in the emergence of nutrition as a science and its importance for health and longevity. The discovery of phagocytosis by Metchnikoff and of its evolutionary ancestry are at the origin of the emergence of cellular immunity as an independent science besides humoral immunity...

OBJECTIVE: Schizophrenia may be the result of a failure of the normal lateralization process of the brain. However, whole-brain asymmetry has not been assessed up to date. Here, we propose a novel measure of global brain asymmetry based on the Dice coefficient to quantify similarity between brain hemispheres. METHOD: Global gray and white matter asymmetry was calculated from high-resolution T1 structural images acquired from 24 patients with schizophrenia and 26 healthy controls, age- and sex-matched...

Youtiao is a typical, traditional, and widely consumed fried food in China. Fermentation of Youtiao involves the use of aluminium potassium sulphate (alum). There are health concerns related to the levels of aluminium in food; therefore, we aimed to determine the aluminium concentrations of Youtiao from various locations, and estimate the dietary exposure by different age groups in Southern and Northern China. The aluminium content of Youtiao samples varied considerably (range: 4.46 to 852.69 mg.kg(-1)). Both the mean and median aluminium contents of Youtiao exceeded 100 mg...

BACKGROUND: Tutorial assistance is related to extra time and cost, and the hospitals' financial compensation for this activity is under debate. We therefore aimed at quantifying the extra time and resulting cost required to train one surgical resident in the operating theatre for board certification in Switzerland as an example of a training curriculum involving several surgical subspecialties. Additionally, we intended to quantify the percentage of tutorial assistance. METHODS: We analysed 200,700 operations carried out between 2008 and 2012...

Background: Information about nutritional risk factors of functional limitation is scarce. The aim of this study was to examine the association between the Mediterranean diet and risk of physical function impairment in older adults. Methods: We used data from 1,630 participants in the Seniors-ENRICA cohort aged ≥60 years. In 2008-2010, adherence to the Mediterranean diet pattern was measured with the Mediterranean Diet Score (MDS) and the Mediterranean Diet Adherence Screener (MEDAS)...

Objectives: The religious landscape of older adults around the world is changing profoundly. Yet until now, no study has chronicled these changes or compared expected aging patterns of religious groups. Differential aging among religious groups can have important economic and social consequences. This study estimates and projects the future religious composition by age at the global and regional levels. Method: This study presents estimates of age structures by religion for 2010 and projections until 2050...

BACKGROUND: Safe management of the second stage of labor is of great importance. Unnecessary interventions should be avoided and correct timing of interventions focused. Ultrasound assessment of fetal position and station has a potential to improve the precision in diagnosing and managing prolonged or arrested labors. The decision to perform vacuum delivery is traditionally based on subjective assessment by digital vaginal examination and clinical expertise and there is currently no method of objectively quantifying the likelihood of successful delivery...

BACKGROUND: In total hip arthroplasty (THA), the acetabular cup and femoral stem must be correctly sized and positioned to avoid intraoperative and postoperative complications, achieve good functional outcomes and ensure long-term survival. Current two-dimensional (2D) techniques do not provide sufficient accuracy, while low-dose biplanar X-rays (EOS) had not been assessed in this indication. Therefore we performed a case-control study to: 1) evaluate the prediction of stem and cup size for a new 3D planning technique (stereoradiographic imaging plus 3D modeling) in comparison to 2D templating on film radiographs and 2) evaluate the accuracy and reproducibility of this 3D technique for preoperative THA planning...

OBJECTIVES: Most US studies of national trends in medical and nonmedical use of prescription opioids have focused on adults. Given the limited understanding in these trends among adolescents, we examine national trends in the medical and nonmedical use of prescription opioids among high school seniors between 1976 and 2015. METHODS: The data used for the study come from the Monitoring the Future study of adolescents. Forty cohorts of nationally representative samples of high school seniors (modal age 18) were used to examine self-reported medical and nonmedical use of prescription opioids...
