The mini mental state examination (MMSE) is a validated tool to assess global cognitive function. Training is required before scoring. Inaccurate scoring can lead to inappropriate medical decisions. In France, MMSE is usually scored by medical students. To assess if medical French students know how to properly score a mini mental state examination. Two « physician-patient » role playings performed by 2 specialized physicians, were performed in front of University Paris V medical students. Role playing A: Scoring of a MMSE according to a script containing five tricks; Role playing B: Find the 5 errors committed in a pre-filled MMSE form, according to the second script...

Magnetic resonance imaging (MRI) serves as the principal imaging modality to diagnose and plan treatment for children with cutaneous vascular anomalies. While routine MRI protocols can lead to the correct diagnosis in the majority of cases, the imaging appearances can sometimes be nonspecific or confusing, yielding more than one possible diagnosis. This review highlights specific MRI sequence recommendations and scanning tips that can optimize the imaging protocol to increase diagnostic confidence.

Performing deceptive actions is a wide-spread phenomenon in sports and it is of considerable practical relevance to know whether or not a fake or a disguised action decreases the opponents' performance. Therefore, research on deceptive actions for various sport disciplines (e.g., cricket, rugby, martial arts, soccer, and basketball) has been conducted. This research is scattered, both across time and scientific disciplines. Here, we aim to systematically review the empirical work on deceptive actions in interactive sports and want to give an overview about several issues investigated in the last decades...

As surgical proficiency and the development of medical techniques have improved, uniportal video-assisted thoracoscopic surgery (VATS) has emerged as a minimally invasive alternative in the surgical management of lung cancer. The spectrum of uniportal VATS indications is now almost equal to that of conventional VATS. Recent decades have witnessed the emergence of numerous uniportal VATS techniques. A significant proportion of these have to be converted into a multiport approach and even open thoracotomy due to the difficulty of managing the upper lobe vein and bronchus, particularly for the technically challenging left upper lobectomy...

BACKGROUND: Nipple-areola complex (NAC) sparing mastectomy (NSM) is mostly indicated in patients with small-/medium-sized and non-ptotic breasts, while skin-reducing mastectomy is used in patients with medium or large breasts with severe ptosis. NAC location on the reconstructed breast is one of the major factors in determining the final aesthetic result and patients' satisfaction. An optimum result obtained at the end of surgical procedure may be altered and compromised by skin redistribution and consequently NAC depositioning during the post-operative period in patients with medium-sized breasts and a moderate degree of ptosis...

Posterior retroperitoneoscopic adrenalectomy has recently increased in popularity and currently adopted in about 20% of referral centers. It may provide more direct access to the adrenals, thus avoiding post-operative adhesions and the need for patient repositioning in bilateral adrenalectomy. Although it has been suggested to be feasible for large tumors, large tumor size is indicated as the main limitation of PRA, mainly because of the small space available for dissection.

This study compared visual search under everyday conditions among participants across the life span (healthy participants in 4 groups, with average age of 6 years, 8 years, 22 years, and 75 years, and 1 group averaging 73 years with a history of falling). The task involved opening a door and stepping into a room find 1 of 4 everyday objects (apple, golf ball, coffee can, toy penguin) visible on shelves. The background for this study included 2 well-cited laboratory studies that pointed to different cognitive mechanisms underlying each end of the U-shaped pattern of visual search over the life span (Hommel et al...

Selecting functional genes is essential for analyzing microarray data. Among many available feature (gene) selection approaches, the ones on the basis of the large margin nearest neighbor receive more attention due to their low computational costs and high accuracies in analyzing the high-dimensional data. Yet there still exist some problems that hamper the existing approaches in sifting real target genes, including selecting erroneous nearest neighbors, high sensitivity to irrelevant genes, and inappropriate evaluation criteria...

The normal mapping technique is widely used in computer graphics to visualize three-dimensional (3D) objects displayed on a flat screen. Taking advantage of optical properties of metasurfaces, which provide a highly efficient approach for manipulation of incident light wavefront, we have designed a metasurface to implement diffuse reflection and used the concept of normal mapping to control its scattering properties. As a proof of principle, we have fabricated and characterized a flat diffuse metasurface imitating lighting and shading effects of a 3D cube...

PURPOSE: To describe a technical trick to overcome a prior failed retrograde puncture of the tibial vessels secondary to arterial calcification. TECHNIQUE: Following a prior failed retrograde puncture attempt, the needle is left in place next to the artery. The tip of the needle is then moved toward the artery as a lever so that the artery is fixed between the needle, the skin, and the surrounding tissues. With the artery fixed, a standard puncture procedure is performed...

In the field of medicine, there are a large number of new drugs synthesis every year. Before entering the clinical stage, it needs a lot of work on drug testing of the various properties. Due to the lack of a large number of laboratory technician, laboratory equipment and reagents, the drug testing of many biochemical properties are not completed. Theoretical medicine provides a theoretical way for medical researchers to obtain the pharmaceutical properties of compounds by calculation tricks. In this paper, the first multiplication atom-bond connectivity index of several common drugs structure are studied, and the accurate expressions are determined...

Endurance exercise training promotes numerous cellular adaptations in both cardiac myocytes and skeletal muscle fibers. For example, exercise training fosters changes in mitochondrial dynamics including increased mitochondrial biogenesis and accelerated mitochondrial turnover. Additionally, endurance exercise training alters the abundance of numerous cytosolic and mitochondrial proteins in both cardiac and skeletal muscle myocytes, resulting in a protective phenotype in the active fibers; this exercise-induced protection of cardiac and skeletal muscle fibers is often referred to as "exercise preconditioning...

Optimal control theory and machine learning techniques are combined to formulate and solve in closed form an optimal control formulation of online learning from supervised examples with regularization of the updates. The connections with the classical linear quadratic gaussian (LQG) optimal control problem, of which the proposed learning paradigm is a nontrivial variation as it involves random matrices, are investigated. The obtained optimal solutions are compared with the Kalman filter estimate of the parameter vector to be learned...

In this article, we present a complete automated system for spotting a particular slice in a complete 3D Computed Tomography exam (CT scan). Our approach does not require any assumptions on which part of the patient's body is covered by the scan. It relies on an original machine learning regression approach. Our models are learned using the transfer learning trick by exploiting deep architectures that have been pre-trained on imageNet database, and therefore it requires very little annotation for its training...

INTRODUCTION: Trocar dislodgment can occur frequently during minimally invasive surgery. Closing the entry port at the fascial layer after the end of a long laparoscopic surgery is time-consuming. Here, I introduce Tehran's Tie, a simple trick to overcome these problems. MATERIALS AND SURGICAL TECHNIQUE: After the first trocar site has been created with the open technique and before the first port is inserted, the fascial wound is grasped with a loop of nylon thread, similar to a transverse matrix suture...

In many computer vision and machine learning applications, the data sets distribute on certain low-dimensional subspaces. Subspace clustering is a powerful technology to find the underlying subspaces and cluster data points correctly. However, traditional subspace clustering methods can only be applied on data from one source, and how to extend these methods and enable the extensions to combine information from various data sources has become a hot area of research. Previous multi-view subspace methods aim to learn multiple subspace representation matrices simultaneously and these learning task for different views are treated equally...
