The habilitation nursing of children with developmental disabilities—Beyond traditional nursing practices and principles?
2014
Research-based descriptions of the contents of the habilitation nursing of children with developmental disabilities are lacking. The objective of this qualitative study was to describe the habilitation nursing of children with developmental disabilities in a Finnish children’s neurological ward. In addition, the purpose was to outline the principles that directed the nursing functions (which consisted of various nursing interventions). The data collection included observation, a retrospective think-aloud method with video-taped nursing situations, the nursing records, and an open-ended questionnaire. The data were analysed with a qualitative content analysis of the manifest and latent conte…
Optical release of caged glutamate for stimulation of neurons in the in vitro slice preparation
2005
Optical stimulation techniques prove useful to map func- tional inputs in the in vitro brain slice preparation: Glutamate released by a focused beam of UV light induces action potentials, which can be detected in postsynaptic neurons. The direct activation effect is influenced by factors such as compound concentration, focus depth, light absorption in the tissue, and sensitivity of different neuronal do- mains. We analyze information derived from direct stimulation ex- periments in slices from rat barrel cortex and construct a computa- tional model of a layer V pyramidal neuron that reproduces the experimental findings. The model predictions concerning the influ- ence of focus depth on inpu…
Glutathione protects metastatic melanoma cells against oxidative stress in the murine hepatic microvasculature.
1998
Calcein-labeled B16 melanoma (B16M) cells were injected intraportally, and in vivo video microscopy was used to study the distribution and damage of cancer cells arrested in the liver microvasculature over a period of 4 hours. The contribution of glutathione (GSH)-dependent antioxidant machinery to the possible oxidative stress-resistance mechanism of B16M cell was determined by in vitro incubation with the selective inhibitor of GSH synthesis L-buthionine (S,R)-sulphoximine (BSO) before B16M cell injection in untreated and 0.5-mg/kg lipopolysaccharide (LPS)-treated mice. In addition, untreated and LPS-treated isolated syngeneic hepatic sinusoidal endothelial cells (HSE) were used to determ…
Computational fluid dynamics in the assessment of patients' postoperative status after glottis-widening surgery
2017
Background. Computational fluid dynamics (CFD), a rapidly developing instrument with a number of practical applications, allows calculation and visualization of the changing parameters of airflow in the upper respiratory tract. Objectives. The aim of this study was to demonstrate the advantages of CFD as an instrument for noninvasive tests of the larynx in patients who had undergone surgical treatment due to bilateral vocal fold paralysis. Material and Methods. Surface measurements of the glottic space were made during maximum adduction of the vocal folds. Additionally, the following spirometric parameters were determined: forced vital capacity (FVC), forced expiratory volume in the first s…
Psychogenic nonepileptic seizures in pediatric population: A review
2019
Abstract Introduction Psychogenic nonepileptic seizures (PNES) are observable abrupt paroxysmal changes in behavior or consciousness that resemble epileptic seizures, but without concurrent electroencephalographic abnormalities. Methods In this manuscript, we reviewed literature concerning pediatric PNES and focused on those articles published in the last 10 years, in order to try to understand what the state of the art is at the moment, particularly as regards relationship and differential diagnosis with epilepsy. Results Psychogenic nonepileptic seizures have been extensively described in literature mainly in adults and less frequently in children. Despite the potential negative impact of…
Experimental evidence for suspence as determinant of video game enjoyment
2009
Based on theoretical assumptions from film psychology and their application to video games, the hypothesis is tested that suspense is a major factor in video game enjoyment. A first-person shooter game was experimentally manipulated to create either a low level or a high level of suspense. Sixty-three participants were randomly assigned to experimental conditions; enjoyment was assessed after playing by a 10-item rating scale. Results support the assumption that suspense is a driver of video game enjoyment. © 2009 Mary Ann Liebert, Inc.
Effectiveness of a videoconference training course on implementing pharmacy services
2009
Objective The aim of this research was to assess the effects of a series of four training courses comprised of 13 synchronous videoconferences on the implementation of cognitive services in Spanish community pharmacies. Setting A phone survey to continuing training course attendants. Methods A random sample of 225 pharmacists registered in a 2004 videoconference course was selected. The phone-survey questionnaire included quality perception elements rated on a 5-point Likert scale, and a series of questions used to identify position in the Rogers 5-step innovation-decision model. An algorithm was used to translate the questions into Rogers' categories. To discover determinants of attendants…
Aircraft noise exposure drives the activation of white blood cells and induces microvascular dysfunction in mice
2021
Epidemiological studies showed that traffic noise has a dose-dependent association with increased cardiovascular morbidity and mortality. Whether microvascular dysfunction contributes significantly to the cardiovascular health effects by noise exposure remains to be established. The connection of inflammation and immune cell interaction with microvascular damage and functional impairment is also not well characterized. Male C57BL/6J mice or gp91phox−/y mice with genetic deletion of the phagocytic NADPH oxidase catalytic subunit (gp91phox or NOX-2) were used at the age of 8 weeks, randomly instrumented with dorsal skinfold chambers and exposed or not exposed to aircraft noise for 4 days. Pro…
Comparative intention-to-treat analysis of the video-assisted thoracoscopic surgery approach to pulmonary segmentectomy for lung carcinoma
2015
Objectives To compare the video-assisted thoracoscopic surgery (VATS) with the open thoracotomy access to pulmonary segmentectomy by the clinical outcomes and long-term survival in lung carcinoma. Methods Non-randomized comparative intention-to-treat study of prospective institutional registry data and survival data of 100 consecutive patients undergoing segmentectomy. Results Within one decade (2002-12), 100 patients with proven or highly suspected lung carcinoma underwent 100 anatomical sub-lobar pulmonary resections (52 typical and 20 atypical segmentectomies, 28 split-lobe procedures). Fifty-six patients were operated by VATS and 44 by thoracotomy access. Comparison of demographic, medi…
Loss of self-control as excuse in group-therapy conversations for intimately violent men.
2006
This article examines the constructions of loss of self-control by male perpetrators of intimate violence in therapy-group conversations. It looks at discursive strategies used by therapists and clients in therapy-group negotiations concerning the issue of self-control. The data are part of a larger corpus of videotaped and transcribed recordings of treatment groups for male perpetrators and consists of four treatment group processes. The analysis concentrates on episodes of self-control talk where a participant referred to loss of self-control when accounting for his violent behavior. The loss of self-control was found to be a fundamental constituent of excuses and was used to account for …
