Multidimensional instruments with an integral approach to identify frailty in community-dwelling people: protocol for a systematic psychometric review

2019

IntroductionAn increasing number of investigations highlight the complex nature of frailty; therefore, the use of multidimensional assessment instruments could be useful in clinical decision-making. Frail people are found mainly in the community setting which is why this is the ideal environment for early screening and intervention. For this purpose, it is necessary to have valid, time-effective and easy-to-use frailty assessment instruments. The aim of this review is to critically appraise, compare and summarise the quality of the measurement properties of all multidimensional instruments with an integral approach to identify frailty in community-dwelling people.Methods and analysisMedline…

Chronic pain affects the whole person--a phenomenological study.

2014

The aim of this qualitative study was to explore participants' perspectives on the effects of chronic pain on the psychophysical unity.Thirty-four chronic pain outpatients were interviewed, and the transcribed interviews were analysed with Giorgi's four-phase phenomenological method. The mean age of the participants was 48 years, and 19 of them were women. For 21 of the participants, the pain duration was more than 5 years, and most had degenerative spinal pain.The results of this whole research project indicated that the phenomenon chronic pain consisted of four essential themes: Pain affects the whole person, invisibility, negativity, and dominance of pain. This study concentrates only on…

Associations of neuroticism with falls in older adults : do psychological factors mediate the association?

2020

OBJECTIVES Neuroticism predicts falls in older people. In addition, concern about falling and depressive symptoms are associated with fall risk. This study examined whether concern about falling and depressive symptoms mediate the association between neuroticism and falls. METHOD Cross-sectional data on 314 community-dwelling people aged 70–85 years were utilized. Neuroticism was assessed with a short modified form of the Eysenck Personality Inventory. Indoor and outdoor falls during the past year were self-reported. Concern about falling was assessed with the Falls Efficacy Scale-International and depressive symptoms with the Geriatric Depression Scale-15. Path modeling was used to examine…

Ultrafast Interface Charge Separation in Carbon Nanodot-Nanotube Hybrids

2021

Carbon dots are an emerging family of zero-dimensional nanocarbons behaving as tunable light harvesters and photoactivated charge donors. Coupling them to carbon nanotubes, which are well-known electron acceptors with excellent charge transport capabilities, is very promising for several applications. Here, we first devised a route to achieve the stable electrostatic binding of carbon dots to multi- or single-walled carbon nanotubes, as confirmed by several experimental observations. The photoluminescence of carbon dots is strongly quenched when they contact either semiconductive or conductive nanotubes, indicating a strong electronic coupling to both. Theoretical simulations predict a favo…

Energy level determination of purine containing blue light emitting organic compounds

2018

Organic light emitting diodes (OLED) have found their applications in the mobile and TV screens. Till now the commercially available diodes are made by expensive thermal evaporation in a vacuum. The costs of OLED fabrication could be decreased by applying low-cost wet casting methods, for example, spin-coating. In this work, we have studied a group of blue light emitting purine derivatives which could potentially be used in OLEDs. The advantage of these compounds is their ability to form amorphous thin films from solutions. All the thin films were prepared by the spincoating method from chloroform solution on ITO glass. The position of hole and electron transport energy levels is important …

High-affinity and selective detection of pyrophosphate in water by a resorcinarene salt receptor

2017

N-Alkyl ammonium resorcinarenes selectively bind pyrophosphate in pure water with an exceptionally high binding constant of up to 1.60 × 107 M–1, three orders of magnitude higher than ATP.

Python moduļa izstrāde un integrācija tīmekļa operētājsistēmā webAppOS drošības funkcionalitātes nodrošināšanai

2022

Tīmekļa operētājsistēma webAppOS ir infrastruktūra, kas ietver sevī vairākus tīmekļa procesorus jeb moduļus, kas ļauj vienā tīmekļa lietotnē izsaukt klašu metodes, kas ir realizētas dažādas programmēšanas valodās. Šī darba mērķis ir izveidot Python moduli un ieintegrēt to webAppOS vidē. Modulis dos izstrādātājiem iespēju veidot klašu metodes Python programmēšanas valodā. Moduli ir paredzēts lietot drošības funkcionalitātes nodrošināšanai, tas ir, automātiskai HTTPS komunikācijas protokola sertifikātu ģenerēšanai un sistēmas mapju šifrēšanai. Šiem nolūkiem tiks izmantoti, attiecīgi, RSA un AES algoritmi, kas ļauj sasniegt augstu drošības līmeni, netērējot daudz resursu.

Symptoms and signs of chronic venous disorders: can we put an end to the controversy

Controversies surrounding symptoms and signs of chronic venous disorders

2016

Association of so-called venous symptoms (aching, itching, tingling, burning sensation, swelling, easily fatigued legs, leg heaviness, and leg restlessness) with chronic venous disease (CVD) still remains a controversial issue. Although these symptoms and a decreased quality of life are common in patients with venous incompetence, and are even more frequent in those with a history of venous thrombosis and/or recurrent and bilateral varicose veins, research has actually revealed that these complaints are poorly correlated with objective signs of venous insufficiency. A venous source for these complaints is obvious in patients with advanced CVD, but a substantial part of venous symptoms, espe…
