Assessment of the quality of life (QoL) of patients with dermatitis and the impact of patch testing on QoL : A study of 519 patients diagnosed with dermatitis

Background: Dermatitis can impair the quality of life (QoL) of patients. Knowledge of the QoL-associated factors and the impact of patch testing on QoL is limited. Objectives: To identify demographic and clinical factors affecting QoL, and to measure the impact of patch testing on QoL of dermatitis patients. Methods: The data and Dermatology Life Quality Index (DLQI) questionnaires of 519 dermatit

SwedeAmp—the Swedish Amputation and Prosthetics Registry : 8-year data on 5762 patients with lower limb amputation show sex differences in amputation level and in patient-reported outcome

Background and purpose — For want of national guidelines for lower limb amputation (LLA) the quality registry SwedeAmp was started in 2011 to increase knowledge around LLA and prosthetic rehabilitation. We now present data from the first 8 years of registration. Patients and methods — We present descriptive data from the first 8 years (2011–2018) of registration. Patient-reported outcome was colle

Modeling and quality assessment of nystagmus eye movements recorded using an eye-tracker

Mathematical modeling of nystagmus oscillations is a technique with applications in diagnostics, treatment evaluation, and acuity testing. Modeling is a powerful tool for the analysis of nystagmus oscillations but quality assessment of the input data is needed in order to avoid misinterpretation of the modeling results. In this work, we propose a signal quality metric for nystagmus waveforms, the

A combined cell and gene therapy approach for homotopic reconstruction of midbrain dopamine pathways using human pluripotent stem cells

Midbrain dopamine (mDA) neurons can be replaced in patients with Parkinson's disease (PD) in order to provide long-term improvement in motor functions. The limited capacity for long-distance axonal growth in the adult brain means that cells are transplanted ectopically, into the striatal target. As a consequence, several mDA pathways are not re-instated, which may underlie the incomplete restorati

Picornavirus May Be Linked to Parkinson’s Disease through Viral Antigen in Dopamine-Containing Neurons of Substantia Nigra

Parkinson’s disease (PD) is a neurodegenerative disease linked with the loss of dopaminer-gic neurons in the brain region called substantia nigra and caused by unknown pathogenic mecha-nisms. Two currently recognized prominent features of PD are an inflammatory response manifested by glial reaction and T-cell infiltration, as well as the presence of various toxic mediators derived from activated g

Isolation and Crystallization of the D156C Form of Optogenetic ChR2

Channelrhodopsins (ChRs) are light-gated ion channels that are receiving increasing attention as optogenetic tools. Despite extensive efforts to gain understanding of how these channels function, the molecular events linking light absorption of the retinal cofactor to channel opening remain elusive. While dark-state structures of ChR2 or chimeric proteins have demonstrated the architecture of non-

When is work a cause of early retirement and are there any effective organizational measures to combat this? A population-based study of perceived work environment and work-related disorders among employees

Background: The ageing workforce has an impact on public health. The aim of this study was to evaluate work-related disorders, work tasks and measures associated with the possibility of working beyond 65 years of age or not. Method: The data comprised two sample surveys based on the Swedish population: the Survey of National Work-Related Health Disorders, and the National Work Environment Survey.

Risk assessment in PAH using quantitative CMR tricuspid regurgitation : relation to heart catheterization

AIMS: Improved risk stratification is of value for decision making in pulmonary arterial hypertension (PAH). Right heart catheterization combined with quantitative tricuspid regurgitation (TR) by cardiovascular magnetic resonance (CMR) may provide this. The aims were to study: (i) to what extent quantitative TR is associated with event-free survival; (ii) how quantitative TR is related to known pr

Psychometric evaluation of the Swedish Quality of Dyadic Relationships scale – homogeneity and construct validity

Rationale and aims: The Quality of Dyadic Relationships is a self-assessment scale used to evaluate various aspects of relationship quality. Psychometric evaluation by the developers of the instrument has led to a nontested amended version. Further psychometric testing is thus warranted, and the aim of this study was to evaluate homogeneity, construct validity (in terms of concurrent, discriminant

A trial of consent procedures for future research with clinically derived biological samples

BACKGROUND: The aims of this study were to determine which consent procedure patients prefer for use of stored tissue for research purposes and what the effects of consent procedures on actual consenting behaviour are.METHODS: We offered 264 cancer patients three different consent procedures: 'one-time general consent' (asked written informed consent), 'opt-out plus' (had the opportunity to opt ou

Type I General Exponential class of distributions

We introduce a new family of continuous distributions and study the mathematical properties of the new family. Some useful characterizations based on the ratio of two truncated moments and hazard function are also presented. We estimate the model parameters by the maximum likelihood method and assess its performance based on biases and mean squared errors in a simulation study framework.

Deterritorializing Cyber Security and Warfare in Palestine: Hackers, Sovereignty, and the National Cyberspace as Normative

Cyber security strategies operate on the normative assumption that national cyberspace mirrors a country's territorial sovereignty. Its protection commonly entails practices of bordering through infrastructural control and service delivery, as well as the policing of data circulation and user mobility. In a context characterized by profound territorial fragmentation, such as the Occupied Palestini

Parameter Estimation from the Cross-Spectrogram Reassignment Vectors

In this paper we propose a novel technique to estimate the parameters of two Gaussian envelope oscillatory signals, with the same time-locations and oscillatory frequencies but possibly different phases. The phase difference and the length of the Gaussian envelope are estimated directly from the slopes of the corresponding cross-spectrogram reassignment vectors. Including the phase difference and

A Security Framework in Digital Twins for Cloud-based Industrial Control Systems: Intrusion Detection and Mitigation

With the help of modern technologies and advances in communication systems, the functionality of Industrial control systems (ICS) has been enhanced leading toward to have more efficient and smarter ICS. However, this makes these systems more and more connected and part of a networked system. This can provide an entry point for attackers to infiltrate the system and cause damage with potentially ca
