Gijsbert J Hötte, Daniël P de Bruyn, Joeri de Hoog
INTRODUCTION: Many authors have reported on a myopic post-operative refractive prediction error when combining phacoemulsification with pars plana vitrectomy (phacovitrectomy). In this study we evaluate the amount of this error in our facility and try to elucidate the various factors involved. METHODS: This was a retrospective study which included 140 patients who underwent phacovitrectomy (39 with macular holes, 88 with puckers, and 13 with floaters). Post-operative refractive error was defined as the difference between the actual spherical equivalent (SEQ) and expected SEQ based on the SRK/T and Holladay-II formulas...

Introduction The role of phase I cancer trials is constantly evolving and they are increasingly being used in 'go/no' decisions in drug development. As a result, there is a growing need to ensure trials are published when completed. There are limited data on the publication rate and the factors associated with publication in phase I trials. Methods The ClinicalTrials.gov database was searched for completed adult phase I cancer trials with reported results. PubMed was searched for matching publications published prior to April 1, 2017...

Jing Yang, Alessandro Piai, Hong-Bin Shen, James J Chou
Nuclear magnetic resonance (NMR) has been an important source of structural restraints for solving structures of oligomeric transmembrane domains (TMDs) of cell surface receptors and viral membrane proteins. In NMR studies, oligomers are assembled using inter-protomer distance restraints. But, for oligomers that are higher than dimer, these distance restraints all have two-fold directional ambiguity, and resolving such ambiguity often requires time-consuming trial-and-error calculations using restrained molecular dynamics (MD) with simulated annealing (SA)...

A competent DNA damage response (DDR) helps prevent cancer, but once cancer has arisen DDR can blunt the efficacy of chemotherapy and radiotherapy which cause lethal DNA breakage in cancer cells. Thus, blocking DDR may improve the efficacy of these modalities. Here we report a new DDR mechanism that interfaces with inflammatory signaling and might be blocked to improve anticancer outcomes. Specifically, we report that the ubiquitin-editing enzyme A20 binds and inhibits the E3 ubiquitin ligase RNF168, which is responsible for regulating histone H2A turnover critical for proper DNA repair...

Xiangming Xu, Dingbang Xiao, Wenyin Li, Qiang Xu, Zhanqiang Hou, Xuezhong Wu
This paper reports a dual-butterfly structure gyroscope based on the traditional butterfly structure. This novel structure is composed of two butterfly structures, each of which contains a main vibrational beam, four proof masses, and a coupling mechanism. The coupling mechanism in this proposed structure couples the two single butterfly structures and keeps the driving mode phases of the two single butterfly gyroscopes exactly opposite, increasing the double difference of traditional butterfly gyroscopes to a quad difference, which has the potential advantage of improving bias instability and g-sensitivity...

Athel Cornish-Bowden
Enthalpy-entropy compensation supposes that differences in activation enthalpy ΔH++ for different reactions (or, typically in biochemistry, the same reaction catalysed by enzymes obtained from different species) may be compensated for by differences in activation entropy ΔS++. At the isokinetic temperature the compensation is exact, so that all samples have the same activity. These ideas have been controversial for several decades, but examples are still frequently reported as evidence of a real phenomenon, nearly all of the reports ignoring or discounting the possibility of a statistical artefact...

Sinus augmentation is a predictable procedure that is often required when restoring the posterior maxilla with dental implants. Even with high success rates, careful pre-surgical planning is crucial. A 3D model is a valuable aid for the clinician as it allows for pre-operative simulation, which can reduce surgical time, reduce the risk of intra-operative complications and decrease the potential for error. The aim of this case report is to focus on how such a model is useful when undertaking a sinus augmentation procedure with simultaneous implant placement...

Fei Gao, Wahida Kihal, Nolwenn Le Meur, Marc Souris, Séverine Deguen
BACKGROUND: Spatial accessibility indices are increasingly applied when investigating inequalities in health. Although most studies are making mentions of potential errors caused by the edge effect, many acknowledge having neglected to consider this concern by establishing spatial analyses within a finite region, settling for hypothesizing that accessibility to facilities will be under-reported. Our study seeks to assess the effect of edge on the accuracy of defining healthcare provider access by comparing healthcare provider accessibility accounting or not for the edge effect, in a real-world application...

BACKGROUND: Low back pain and neck-shoulder pain are the most reported types of work-related musculoskeletal disorders, and performing heavy lifting at work and working with trunk rotation increase the risk of developing work-related musculoskeletal disorders. Surface electromyography (sEMG) provides information about the electrical activity of muscles. Thus it has the potential to retrieve indirect information about the physical exposure of specific muscles of workers during their actual work...

Flexible fiberoptic bronchoscopy is often the initial technique for diagnosis of lung and bronchial tumors. Many studies have shown the high accuracy rate of bronchial washing and brushing cytology in the evaluation of neoplastic and non-neoplastic bronchopulmonary lesions. The aim of this study is to emphasize the value of the bronchial cytologic findings for diagnosis of non-neoplastic bronchopulmonary lesions. In a cross-sectional study, we retrieved all cases with bronchial washing and brushing cytology from 21 Mach 2014 to 21 December 2015...

Objectives: Duration of tasks in a job is an essential interest in occupational epidemiology. Such duration is frequently measured using self-reports, which may, however, be associated with both bias and random errors. The present systematic literature review examines the correctness of self-reported durations of tasks, i.e. the extent to which they differ from more valid reference data due to either systematic or random errors, and factors influencing this correctness, with particular emphasis on the assessment of exposures of relevance to musculoskeletal disorders...

John M Eisenberg
Since the release of the report of the Institute of Medicine on medical errors and patient safety in November 1999, health policy makers and health care leaders in several nations have sought solutions that will improve the safety of health care. This attention to patient safety has highlighted the importance of a learning approach and a systems approach to quality measurement and improvement. Balanced with the need for public disclosure of performance, confidential reporting with feedback is one of the prime ways that nations such as the United States, Canada, the United Kingdom, and Australia have approached this challenge...

Gyorgy Paragh, Nathalie C Zeitouni
OBJECTIVE: To evaluate the ability of two-step irradiance to maintain pain control during red light 5-aminolevulinic acid (ALA) photodynamic therapy (PDT) for actinic keratoses (AK) and assess factors influencing pain. BACKGROUND: PDT provides excellent clinical and cosmetic results in the treatment AK and early basal cell carcinomas (BCC). Widespread use of PDT is limited, in part, by pain. A two-step irradiance method for PDT has previously been shown to significantly reduce PDT-associated pain during the treatment of BCC, but the ability of this method to limit pain during the treatment of AKs has not been reported...

Smith-Lemli-Opitz syndrome (SLOS) is a metabolic disorder caused by an inborn error of cholesterol synthesis that affects the development of many organ systems. Malformations in the central nervous system typically involve midline structures and reflect abnormal growth and differentiation of neurons and supporting cells. Despite these defects in central nervous system development, brain tumor formation has only rarely been reported in association with SLOS. We present three individuals with SLOS and lesions in the basal ganglia or brainstem detected by MRI that were concerning for tumor formation...
