Multiple sclerosis (MS) is a chronic disease of the central nervous system characterized by autoimmune inflammation, demyelination, and neurodegeneration. MS is a complex disease that develops under the influence of environmental factors in genetically predisposed individuals. Currently, more than 200 genetic loci associated with MS have been identified by various methods. Some of them are located in the mitochondrial DNA. This paper collects data on mtDNA variants associated with MS in the Russian ethnic group, and shows the possibility of using this information to construct and refine models for predicting the development of MS.

Background: Computed tomography (CT) is the gold standard imaging modality for the assessment of 3D bony morphology but incurs the cost of ionizing radiation exposure. High-resolution 3D magnetic resonance imaging (MRI) with CT-like bone contrast (CLBC) may provide an alternative to CT in allowing complete evaluation of both bony and soft tissue structures with a single MRI examination.
Purpose: To review the technical aspects of an optimized stack-of-stars 3D gradient recalled echo pulse sequence method (3D-Bone) in generating 3D MR images with CLBC, and to present a pictorial review of the utility of 3D-Bone in the clinical assessment of common musculoskeletal conditions.

Imaginal exposure is a standard procedure of cognitive behavioral therapy for the treatment of anxiety and panic disorders. It is often used when in vivo exposure is not possible, too stressful for patients, or would be too expensive. The Bio-Informational Theory implies that imaginal exposure is effective because of the perceptual proximity of mental imagery to real events, whereas empirical findings suggest that propositional thought of fear stimuli (i.

Most women in low- and middle-income countries already receive antenatal care and over half give birth in health facilities. In cities, use of health facilities for childbirth is near universal (>90%).

The study of the predictive ability of a marker is mainly based on the accuracy measures provided by the so-called confusion matrix. Besides, the area under the receiver operating characteristic curve has become a popular index for summarizing the overall accuracy of a marker. However, the nature of the relationship between the marker and the outcome, and the role that potential confounders play in this relationship could be fundamental in order to extrapolate the observed results.

One of the most crucial stages of palliative care is the last days and hours of life, which require special attention and knowledgeable identification of clinical signs described as signs of impending death (SID). Our case series of 11 patients receiving home palliative care describes bilateral hypoactive, stereotyped upper arm movements (scratching of the head, forehead, and nose) that were previously unknown or described, often accompanied by SID.
