Multiple sclerosis (MS) is a chronic neurodegenerative disease that can negatively affect functioning across a wide spectrum of domains. This study aims to investigate the development of mental health and quality of life in MS patients over 18-months and to identify predictive factors.

314 MS outpatients of Virgen Macarena University Hospital in Sevilla/Spain (mean age 45 years, 67.8% women, on average 12.1 years since diagnosis) participated in the study. Health-related quality of life (HRQOL) and mental health were assessed by the 12-Item Short Form Health Survey (SF-12) and the General Health Questionnaire-28 (GHQ-28) twice over an 18-months follow up period.

HRQOL and mental health significantly improved in almost all domains, except for a worsening of vitality. Mental and physical HRQOL improved by a large effect size. Binomial logistic regression models showed that disability status (Expanded Disability Status Scale) predicted both components of HRQOL and age the physical component of HRQOL. Sex, educational level, and disease duration predicted mental health.

Our findings confirm the possibility of a significant large-sized improvement of HRQOL in the course of 18-months even 12 years after MS diagnosis on average. The study showed the importance of sociodemographic as well as clinical variables to predict HRQOL and mental health. Further longitudinal research is needed to better understand their impact on patients' outcomes.

Insufficient water irrigation is one of the serious problems to impair potential yield of agriculturally important sugarcane cash crop by loss in plant performance. Our study aims to reveal consequences of foliar spray of silicon (Si) using calcium metasilicate powder (Wollastonite, CaO.SiO2) to alleviate the adverse effects of limited water irrigation in sugarcane. Silicon (0, 50, 100 and 500 ppm) was applied as foliar spray on normally grown 45 days old sugarcane plants. Further, these plants were raised at half field capacity (50%) using water irrigation precisely up to 90 days under open environmental variables. Consequently, restricted irrigation impaired plant growth-development, leaf relative water content (%), photosynthetic pigments, SPAD unit, photosynthetic performance, chlorophyll fluorescence variable yield (Fv/Fm) and biomass yield. Notably, it has enhanced values of proline, hydrogen peroxide (H2O2), malondialdehyde (MDA), antioxidative defense enzyme molecules viz., catalase (CAT), ascorbate peroxidase (APx) and superoxide dismutase (SOD). The foliar spray of Si defended sugarcane plants from limited water irrigation stress as Si quenched harmful effect of water-deficit and also enhanced the operation of antioxidant defense machinery for improved sugarcane plant performance suitably favored stomatal dynamics for photosynthesis and plant productivity.Heat stress is one of the most important environmental factors that influences wheat growth and development, leading to significant losses in grain yield and has become a significant detrimental factor for worldwide wheat production. In recent years, several studies suggested that eukaryotic elongation factor 1A (eEF1A), may contribute to heat tolerance in plants, therefore the aim of this study was to investigate the accumulation of eEF1A in wheat under conditions of moderate and high air temperatures; to determine the amount of photosynthetic pigments and to determine the yield traits; and to examine whether there is a correlation between eEF1A accumulation, photosynthetic pigments, and yield in different wheat varieties. The results showed that heat stress induced accumulation of eEF1A significantly different among wheat varieties and showed that varieties with a higher accumulation of eEF1A under heat stress are characterized by a smaller decrease in the photosynthetic pigments. A correlation between higher accumulation of eEF1A under heat stress and yield traits was found. Analyzed parameters from two growing seasons, indicated that the higher accumulation of eEF1A and a smaller decrease in photosynthetic pigments distinguishes the varieties more resistant to heat stress. The analysis of the molecular mechanisms by immunoblot, under conditions of high and moderate air temperatures in two growing seasons, aims to develop agricultural strategy and develop wheat varieties tolerant to heat stress.The study consists of a detailed investigation of the degradability of the emerging water contaminant-caffeine by homogeneous and heterogeneous Advanced Oxidation Processes (AOP's), estimation of a synergy index for each hybrid operation thereof, and proposing the most plausible reaction mechanisms that are consistent with the experimental data. It also encompasses evaluation of the effect of the water matrix represented by carbonate species and humic acids, as strong scavengers of hydroxyl radicals. The results showed that single AOP's such as sonolysis (577 kHz) and photolysis with H2O2 provided complete caffeine elimination, but they were insufficient for the mineralization of the compound. Hybrid AOP's were considerably more effective, particularly when operated at a heterogeneous mode using commercial TiO2. The most effective hybrid process was UV-H2O2/TiO2, which provided more than 75% TOC decay at the minimum test doses of the reagent and catalyst. While the addition of ultrasound to the process significantly increased the rate of caffeine decomposition, it reduced the overall degradation of the compound to 64% in terms of TOC decay. The antagonistic effect was attributed to the formation of excess H2O2, and the presence of cavity clouds and/or high density layers that inhibited the transmission of UV light. The effect of natural water ingredients was found to reduce the reaction rates, signifying the major contribution of hydroxyl radicals to the destruction of caffeine. The proposed reaction mechanisms based on OH radical attack and the calculated energy barriers were in good agreement with the experimentally detected reaction byproducts.The power density modulates the dynamics of the chemical reactions during the ultrasonic breakdown of organic compounds. We evaluated the ultrasonic degradation of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) at various power densities (30 W/L-262 W/L) with and without sparging Argon. We observed pseudo-first-order degradation kinetics at an initial PFASs concentration of 100 nM over a range of power density. The rate kinetics of degradation shows a non-linear increase with an increase in power density. We proposed a four-parameter logistic regression (4PLR) equation that empirically fits the degradation rate kinetics with the power density. The 4PLR equation predicts that the maximum achievable half-life of PFOA and PFOS sonochemical degradation are 1 and 10 min under a given set of experimental conditions. The high bulk-water temperature (i.e., 30 °C) of the aqueous sample helps increase the degradation rate of PFOA and PFOS. The addition of oxidants such as iodate and chlorate help enhance PFOA degradation in an argon environment at an ultrasonic frequency of 575 kHz.An 86-year old asymptomatic male was incidentally found to have a variant of levoatrial cardinal vein (LACV) forming a complete venous ring. This is the first report of this variant. Although rare, the ability to identify LACV in the adult population is clinically significant because it may result in bi-directional shunt and the development of symptoms is an indication for intervention.

Relative value units (RVUs) are utilized to evaluate physician productivity in many fields, including radiology. The goal of this paper is to use the electronic medical record (EMR) to evaluate whether the current RVU system allows for fair comparison between radiologists' time effort.

The study was approved by the local Institutional Review Board (IRB). Over 600,000 radiology studies with unique current procedural terminology (CPT) codes were evaluated, and after exclusion of studies interpreted in conjunction with trainees or interpreted using other software systems, a total of 241,627 studies remained. The median 25%ile, 50%ile, 65%ile, 75%ile and modal study ascribable times (SATs) for each CPT code was calculated across all radiologists. To evaluate the potential bias incurred using the current RVU system, the number of days required to achieve the Association of Administrators in Academic Radiology AAARAD 65%ile were calculated.

RVU values were positively correlated with SATs (r = 0.69-0.71, p < 0.001). The variability in the radiologists' time to achieve the AAARAD 65%ile benchmark was highest for musculoskeletal imaging, and lowest for thoracic imaging. The discrepancy in the number of days of work required to achieve the AAARAD 65%ile benchmark was 141.1% (197.7 days) for musculoskeletal imaging, 107.5% (161.9 days) for neuroimaging, 89.6% (185.9 days) for body imaging, and 72.2% (84.0 days) for thoracic imaging.

The current RVU system is not strongly correlated with radiologist effort measured by radiologists' time. A time-based metric is more representative of radiologist work. However, there is no perfect method to measure radiologists' work.

Here we aim to leverage this equivalence to find effective initialisations for weights in the RBM when what is available is a set of noisy examples of each pattern, aiming to translate statistical mechanics background available for HNN to the study of RBM's learning and retrieval abilities. In particular, given a set of definite, structureless patterns we build a sample of blurred examples and prove that the initialisation where w corresponds to the empirical average ξ¯ over the sample is a fixed point under stochastic gradient descent. Further, as a toy application of the duality between HNN and RBM, we consider the simplest random auto-encoder (a three layer network made of two RBMs coupled by their hidden layer) and evidence that, as long as the parameter setting corresponds to the retrieval region of the dual HNN, reconstruction and denoising can be accomplished trivially, while when the system is in the spin-glass phase inference algorithms are necessary. This questions the need for larger retrieval regions which we obtain by applying a Gram-Schmidt orthogonalisation to the patterns in fact, this procedure yields to a set of patterns devoid of correlations and for which the largest retrieval region can be accomplished. Finally we consider an application of duality also in a structured case we test this approach on the MNIST dataset, and obtain that the network performs already ∼67% of successful classifications, suggesting it can be exploited as a computationally-cheap pre-training.
