Patients severing from diabetes mellitus, hypertension and associated complications have recently increased and most of these patients find it extremely difficult to understand or cope with their illness. The objective of this study is to determine the level of patients’ enablement in chronic disease and its predictors. Methods: A community based cross-sectional study was conducted between December 2014 and January 2015. Six hundred and four (604) Patients attending the Chronic Disease Clinic in Alwazarat Health center were randomly selected to participate in the study. Patients aged 18 years and above, who willingly agreed to participate, were included in the study. Self-reported questionnaire was used to determine patient level of enablement. Descriptive statistics such as mean and median were calculated and binary logistic regression was employed to determine the predictors of patient’s enablement to chronic disease. Results: Our results show that five hundred and sixty five (565) out of (604) patients participated in the study with 86.6% response rate. Type 2 diabetes mellitus affecting 40.65% while hypertension affecting 37.79% of the patients in Al wazarat health center. Patient’s enablement to chronic disease was very low and ranged between 2.41 and 1.53 out of 5.0. Binary logistic regression shows that age (male: OR;0.84, 95% CI, 0.72 - 1.04, female. OR;1.04, 95% CI 0.88 - 1.39), marital status (male: OR;0.72, 95% CI 0.54 - 1.11, female: OR 1.01;95% CI 0.82 - 1.29), patient educational level and number of problems discussed with physician and consultation length between male patients and their physician were statistically significant and correlated with patients enablement to chronic disease (P < 0.05). Conclusion: This study shows that patient’s enablement in chronic disease is very low but constitutes an important arm in patients care management. It should be considered as a measurable patient outcome from healthcare services. More prospective studies on this important topic are highly recommended.展开更多

文摘Dear Editor,This letter presents a novel segmentation approach that leverages dendritic neurons to tackle the challenges of medical imaging segmentation.In this study,we enhance the segmentation accuracy based on a SegNet variant including an encoder-decoder structure,an upsampling index,and a deep supervision method.Furthermore,we introduce a dendritic neuron-based convolutional block to enable nonlinear feature mapping,thereby further improving the effectiveness of our approach.

文摘Monitoring the electrophysiology activity of neurons and blood calcium signals can enable a better understanding of disease-related neural system circuits.However,currently,in situ calcium ion monitoring tools are scarce and exhibit low integration and limited sensitivity.In this letter,we propose an implantable probe with an integrated in situ Ag/AgCl reference electrode(ISA/ARE)that can monitor action potential(AP)and Ca^(2+) concentrations.
文摘It is an appealing notion that a protein molecule could act as a nanomagnet.A genetically encodable biomolecule with a permanent magnetic moment at room temperature could have a range of applications:a magnetogenetic actuator,a magnetic tag for purifying and immobilizing enzymes,a contrast agent for magnetic resonance imaging,and a basis for a biomimetic magnetic sensing device,to name just a few.A magnetic protein could perhaps also function as the sensor in the magnetic compass that enables small songbirds to navigate the huge distances between their breeding and wintering grounds.Attractive though such possibilities may be,how realistic are they?
文摘Central venous catheterization establishes temporary,efficient,and rapid use of deep venous access in patients,which provides high flow rate fluid perfusion,enables measurement of central venous pressure,and acts as an important reference for clinical decision-making.However,various complications such as pneumothorax,hemothorax,hematoma,and puncture failure can easily occur during the puncture and catheterization process.

文摘Research of autonomous manufacturing systems is motivated both by the new technical possibilities of cyber-physical systems and by the practical needs of the industry.Autonomous operation in semi-structured industrial environments can now be supported by advanced sensor technologies,digital twins,artificial intelligence and novel communication techniques.These enable real-time monitoring of production processes,situation recognition and prediction,automated and adaptive(re)planning,teamwork and performance improvement by learning.This paper summarizes the main requirements towards autonomous industrial robotics and suggests a generic workflow for realizing such systems.Application case studies will be presented from recent practice at HUN-REN SZTAKI in a broad range of domains such as assembly,welding,grinding,picking and placing,and machining.The various solutions have in common that they use a generic digital twin concept as their core.After making general recommendations for realizing autonomous robotic solutions in the industry,open issues for future research will be discussed.

文摘Ribosome profiling(Ribo-Seg)enables genome-wide survey of translational activities at nucleotide resolution by enriching and sequencing ribosome-protected fragments(RPFs)in the cell(Ingolia et al.,2009).Based on the characteristic distribution of RPFs in Ribo-Seq,such as enrichment in open reading frames(ORFs)and three-nucleotide periodicity,many computational methods have been developed to detect translated ORFs from Ribo-Seq data(Wang et al.,2020a).
