Analysis of the Accuracy of CAM-type Deformity Resection on a Low-cost Arthroscopic Simulator in a Training Scenario.

To evaluate surgeons' performance in resecting CAM-type deformities using a realistic arthroscopic surgery simulator. An arthroscopic simulator was created using low-cost materials with the help of a GTMax Core A1 3D printer and the programs Invesalius and Meshmixer 2017, which were used to develop femoral head parts in ABS material, with the presence of a CAM-type deformity, to mimic a femoroacetabular impact situation. After the operations were performed by 16 surgeons, the femurs were compared to a previous model with deformity and another without, using Cloudcompare, and parameters such as the volumetric difference between the operated femurs, with and without deformity, the minimum and maximum distance between them, the percentage of the deformity resected, the estimated time for total resection of the deformity, as well as a qualitative analysis based on the images and graphs provided by the program representing the areas of the parts resected, were evaluated at the end.

Predicting myopic changes in children wearing glasses using the Plusoptix photoscreener.

Introduction: With high increase in myopia prevalence, we aimed to assess whether Plusoptix_A09 can be used in myopic children over spectacles to predict visual acuity (VA) and myopic refraction changes.

Methods: Myopic children underwent a complete ophthalmological examination. Plusoptix_A09 was performed over spectacles.

Vanadium-Containing Keggin-Type Polyoxometalates, [VMO] and [VVMO] (M = Mo, W): Structural Characterization and Voltammetric, NMR, and EPR Studies Related to Electrochemical Reduction at Framework and Central Vanadium Sites.

Vanadium is accommodated in both the framework (V) and central positions (V) in the Keggin-type polyoxometalates (POMs) [VVMO] (M = Mo, W; VVM) and in the central position in [VMO] (VM). The structures of the VVM class have been determined by X-ray crystallography and compared to those of VM reported previously. A major feature of interest with POMs is their capacity for very extensive reduction, particularly when protonation accompanies the electron transfer step.

A study comparing the WHO C-Model caesarean section rates and observed caesarean section rates at Port Moresby General Hospital, Papua New Guinea.

Background: Worldwide, there is an increase in caesarean deliveries. Ideal caesarean section (CS) rates continue to be a matter for debate. The World Health Organization (WHO) C-Model, is a mathematical modelling tool to assist health facilities estimate expected CS rates based on the quality middle income facilities practice.

Review on microbial fuel cells applications, developments and costs.

The microbial fuel cell (MFC) technology has attracted significant attention in the last years due to its potential to recover energy in a wastewater treatment. The idea of using an MFC in industry is very attractive as the organic wastes can be converted into energy, reducing the waste disposal costs and the energy needs while increasing the company profit. However, taking aside these promising prospects, the attempts to apply MFCs in large-scale have not been succeeded so far since their lower performance and high costs remains challenging.
