Early identification and treatment of high-risk plaques before they rupture, and precipitate adverse events constitute a major challenge in cardiology today. Computational simulations are a time- and cost-effective way to study the performance, and to optimize a system. The main objective of this work is to optimize the flow of a novel atraumatic local drug delivery catheter for the treatment of coronary atherosclerosis. The mixing and spreading effectiveness of a drug fluid was analyzed utilizing computational fluid dynamics (CFD) in a coronary artery model. The optimum infusion flow of the nanoparticle-carrying drug fluid was found by maximizing the drug volume fraction and minimizing drug velocity at the artery wall, while maintaining acceptable wall shear stress (WSS). Drug velocities between 15 m/s and 20 m/s are optimum for local drug delivery. The resulting parameters from this study will be used to fabricate customized prototypes for future in-vivo experiments. Patients with Mucopolysaccharidosis (MPS) have an increased risk of cardiovascular complications, conduction tissue abnormalities and arrhythmia; all rare but underestimated. It has been reported that conduction system defects are progressive in this group of patients and may result in sudden cardiac death. The aim of this study is to review our current practice and suggest best practice guidelines regarding the frequency of cardiac rhythm monitoring in this patient group. Seventy-seven adult MPS patients who attended metabolic clinics between 2013 and 2019 were included in this retrospective observational study. Patients were affected with different MPS types MPS I (n = 33), MPS II (n = 16), MPS IV (n = 19), VI (n = 8) and VII (n = 1). The assessments included 12‑lead electrocardiogram (ECG), 24-h ECG (Holter monitor), loop recorder/pacemaker interrogation assessment. Data from 12‑lead ECG (available from 69 patients) showed a variety of abnormalities T wave inversion in a single lead III (n = 19), left ventdetection of underlying conduction tissue abnormalities. In addition, 12‑lead ECG is the first line investigation that, if abnormal, should be followed up by 24-hour Holter monitoring. KIN-002787 These findings warrant further research studies.

AIM To assess the prognostic meaning of HRR and coronary flow velocity reserve (CFVR). METHODS The study group comprised 2149 patients (1236 men; mean age 66±12 years) with suspected (n=1280) or known (n=869) coronary artery disease and without inducible regional wall motion abnormalities (RWMA) during dipyridamole SE (0.84mg/kg in 6min). We assessed CFVR of the left anterior descending artery with pulsed-wave Doppler as the ratio between hyperaemic peak and basal peak diastolic flow velocities (abnormal value≤2.0). HRR was calculated as the peak/resting ratio of heart rate from a 12-lead electrocardiogram (abnormal value≤1.22). All patients were followed up. RESULTS CFVR and HRR were abnormal in 520 (24%) and 670 (31%) patients, respectively. There was a positive linear correlation between CFVR and HRR (r=0.30; P less then 0.0001). During a median follow-up of 22 months (1st quartile 12 months, 3rd quartile 35 months), 75 (6%) patients died. The annual mortality was 1.6% in the overall population, 0.5% in the 1224 (57%) patients with normal CFVR and HRR, 1.7% in the 405 (19%) patients with abnormal HRR only, 3.6% in the 255 (12%) patients with abnormal CFVR only, and 6.2% in the 265 (12%) patients with abnormal CFVR and HRR. CONCLUSIONS HRR is weakly related to CFVR, and a blunted HRR usefully complements RWMA and CFVR for prediction of outcome with dipyridamole SE. The patient without inducible RWMA is still at intermediate risk, but the risk is low with concomitant preserved CFVR, and very low with concomitant normal HRR. PURPOSE The purpose of this study was to investigate the impact of radiologist experience on diagnostic performance of pelvic magnetic resonance imaging (MRI) for the evaluation of endometriomas and different localisations of deep pelvic endometriosis (DPE). MATERIALS AND METHODS In this prospective study all pelvic MRI examinations performed for pelvic endometriosis from December 2016 to August 2017 were evaluated by readers with different experience levels; junior resident (0-6 weeks of experience in female imaging), senior resident (7-24 weeks), fellow (6-24 months), and expert (10 years) in female imaging for the presence of endometriomas and DPE. Their evaluations were compared with surgery confirmed with pathology. Diagnostic performances of readers with different levels of experience were studied by the means of receiving operating characteristic curves and areas under the curve (AUC) were compared with the ones of the expert reader. RESULTS Of 174 patients evaluated, the standard of reference was available for 59, consisting the final population of the study. The AUC for endometriomas, DPE for the posterior and anterior pelvic compartment, for rectosigmoid DPE and for overall evaluation were 0.983, 0.921, 0.615, 0.862, and 0.914 for the expert reader, 0.966 (p = 0.178), 0.805 (p = 0.001), 0.605 (p = 0.91), 0.872 (p = 0.317), and 0.849 (p = 0.0009) for the fellow level, 0.877 (p = 0.002), 0.757 (p less then 0.001), 0.585 (p = 0.761), 0.744 (p = 0.239), and 0.787 (p =  less then 0.001) for the senior resident level and 0.861 (p = 0.177), 0.649 (p less then 0.001), 0.648 (p = 0.774), 0.862 (p = 1), and 0.721 (p less then 0.001) for the junior resident level. CONCLUSIONS According to our results, interpretation of pelvic MRI for DPE should be performed by specialists as; even the performance of radiologists with up to 2 years of experience in female imaging was statistically inferior to that of experts. RATIONALE AND OBJECTIVES To explore associations between MR imaging features, DNA methylation subtyping, and survival in lower-grade gliomas (LGG). MATERIALS AND METHODS The MR data from 170 patients generated with the Cancer Imaging Archive were reviewed. The correlation was evaluated by Fisher's Exact Test, Pearson Chi-Square and binary regression analysis. Survival analysis was conducted by using time-dependent ROC analysis and the Kaplan-Meier method (the worst prognosis subgroup). RESULTS Identified were 9 (5.3%) M1-subtype, 18 (10.6%) M2-subtype, 48 (28.2%) M3-subtype, 31 (18.2%) M4-subtype and 64 (37.6%) M5-subtype. Patients with M4-subtype had the shortest median OS (49.3 vs. 28.4) months(p median (OR 2.447; p = 0.01; 95%CI 1.244-4.813) were associated with M5-subtype (AUC 0.645). Decision curve analysis indicated predictions for all models were clinically useful. CONCLUSION This preliminary radiogenomics analysis of lower-grade gliomas demonstrated associations between MR features and DNA methylation subtyping. The shortest survival was observed in patients with M4-subtype. And we have constructed nomogram that enables more accurate predictions of M4-subtype. Kyasanur Forest disease (KFD) virus is one of India's severe arboviruses capable of causing prolonged debilitating disease. It has been expanding beyond its historical endemic locus at an alarming rate over the last two decades. The natural nidus of this zoonosis is located in the monsoon rainforest of the Western Ghats, India, which is one of the world's most important biodiversity hotspots. Definitive reservoir hosts for KFD virus (KFDV) have yet to be delineated, and thus much of the infection ecology of this virus, and its consequent transmission dynamics, remains uncertain. Given its unique biogeographical context, identifying ecological parameters of KFDV relevant to the virus' epidemiology has been complex and challenging. The challenge has been exacerbated by diminished research efforts in wildlife surveillance over the last two decades, coinciding with the expansion of the range of KFD across the region. The current investigation sought to define a preliminary ecological profile of KFDV hosts based on their life history and feeding traits to aid in re-establishing targeted wildlife surveillance and to discern those ecological traits of wildlife hosts that may improve our understanding of KFD epidemiology. The importance of fast-living among KFDV hosts was of special interest with respect to the latter aim. We compared mammalian traits between host and non-host species using general additive models and phylogenetic generalised linear models. This study found that both body mass and forest forage were strongly associated with mammalian host infection status, but that reproductive life history traits were not. These findings will help in structuring ecologically based wildlife surveillance and field investigations, while also helping to parameterise novel epidemiological models of zoonotic infection risk that incorporate species functional traits in a region where biogeography, landscape ecology, and community ecology manifest extraordinary complexity, particularly under growing anthropogenic pressure. BACKGROUND & AIMS Compliance to guidelines for disease-related malnutrition is documented as poor. The practice of using paper-based dietary recording forms with manual calculation of the patient's nutritional intake is considered cumbersome, time-consuming and unfeasible among the nurses and does often not lead to appropriate nutritional treatment. We developed the digital decision support system MyFood to deliver a solution to these challenges. MyFood is comprised of an app for patients and a website for nurses and includes functions for dietary recording, evaluation of intake compared to requirements, and a report to nurses including tailored recommendations for nutritional treatment and a nutritional care plan for documentation. The study aimed to investigate the effects of using the MyFood decision support system during hospital stay on adult patients' nutritional status, treatment and hospital length of stay. The main outcome measure was weight change. METHODS The study was a parallel-arm randomized conchange during hospital stay. A higher proportion of the patients in the control group was malnourished or at risk of malnutrition at hospital discharge compared to the patients in the intervention group. The documentation of nutritional intake, treatment and nutritional care plans was higher for the patients using the MyFood system compared to the control group. This trial was registered at clinicaltrials.gov (NCT03412695). BACKGROUND Difficulties with meal-related activities (preparing meals and food shopping) may influence food intake, and contribute to nutritional risk among elderly people. All known studies on this topic had a cross-sectional design, thereby no causal relationships could be derived. We aim to investigate if difficulties with meal-related activities can contribute to subsequent weight loss in community-dwelling older people. METHODS We used data of older subjects from the MAPT Study (n = 1531, median age = 74 years, 64% women), who provided prospective data on weight every 6 months and cognitive, physical condition, and functional capacities every year during a 3-year period. Difficulties preparing meals and shopping were evaluated each year with the Alzheimer's Disease Cooperative Study-Activities of Daily Living Prevention Instrument (ADCS ADL-PI) Scale. The risk of losing weight (≥5% or ≥ 3 kg in the following year) was estimated using a time-dependent Cox regression model. RESULTS During the 3-year follow-up, a total of 851 subjects experienced at least a 5% or 3 kg weight loss.
