The piezoelectric polymer PVDF and its copolymers have a long history as transducer materials for medical and biological applications. An efficient use of these polymers can potentially both lower the production cost and offer an environment-friendly alternative for medical transducers which today is dominated by piezoelectric ceramics containing lead. The main goal of the current work has been to compare the image quality of a low-cost in-house transducers made from the copolymer P(VDF-TrFE) to a commercial PVDF transducer. Several test objects were explored with the transducers used in a scanning acoustic microscope, including a human articular cartilage sample, a coin surface, and an etched metal film with fine line structures. To evaluate the image quality, C- and B-scan images were obtained from the recorded time series, and compared in terms of resolution, SNR, point-spread function, and depth imaging capability. The investigation is believed to provide useful information about both the strengths and limitations of low-cost polymer transducers.

The aim was to describe and compare nursing assistants', enrolled nurses' and registered nurses' perceptions of quality of care, working conditions, competence and personal health in older peoples' care. Altogether 70 nursing assistants, 163 enrolled nurses and 198 registered nurses completed a questionnaire comprising Quality from the Patient's Perspective modified for caregivers, Creative Climate Questionnaire, Stress of Conscience Questionnaire, items on education and competence and Health Index. The caregivers reported higher perceived reality of quality of care in medical-technical competence and physical-technical conditions than in identity-oriented approach and socio-cultural atmosphere. In subjective importance, the highest rating was assessed in one of the physical-technical items. The organisational climate was for three of the dimensions rather close/reached the value for a creative climate, for seven dimensions close to a stagnant climate. In perceived stress of conscience, there were low values. Nursing assistants had lower values than enrolled nurses and registered nurses. The caregivers reported highest values regarding previous education making them feel safe at work and lowest value on the item about education increasing the ability for a scientific attitude. Registered nurses could use knowledge in practice and to a higher degree than nursing assistants/enrolled nurses reported a need to gain knowledge, but the latter more often received education during working hours. The health index among caregivers was high, but registered nurses scored lower on emotional well-being than nursing assistants/enrolled nurses. The caregivers' different perceptions of quality of care and work climate need further attention. Although stress of conscience was low, it is important to acknowledge what affected the caregivers work in a negative way. Attention should be paid to the greater need for competence development among registered nurses during working hours.

BackgroundThe purposes of this study were to investigate the prevalence of psychotropic (hypnotic, antidepressant, and anxiolytic) drug use among adolescents aged 15–16 years during the period 2006–2010 according to gender and subcategories of psychotropics, and to study psychotropic drug use over the period 2007–2010 among incident users in 2007.MethodsThis was a one-year prevalence and follow-up study based on information retrieved from the nationwide Norwegian prescription database for the period 2006–2010. The study population consisted of adolescents aged 15–16 years who had filled at least one prescription for a psychotropic drug in the study period. The main outcome measures were filling of hypnotic, antidepressant, and/or anxiolytic drug prescriptions.ResultsOverall use of psychotropic drugs increased from 13.9 to 21.5 per 1000 among boys and from 19.7 to 24.7 per 1000 among girls during the 2006– 2010 period. Hypnotic drugs, and melatonin in particular, accounted for most of the increase. For melatonin, the annual median amount dispensed was 180 defined daily doses through the period until 2010, at which time it decreased to 90 defined daily doses. In total, 16.4% of all incident psychotropic drug users in 2007 were still having prescriptions dispensed in 2010.ConclusionThis study shows an increase in hypnotic drugs dispensed for adolescents in Norway, mainly attributable to the increasing use of melatonin. The amount of melatonin dispensed indicates more than sporadic use over longer periods, despite melatonin only being licensed in Norway for use in insomnia for individuals aged 55 years or older.

The aim of this study was to explore the nature of nursing care and rehabilitation of female stroke survivors, as described by hospital nurses. The objectives were to uncover how the nurses perceived the care of female stroke survivors and to explore whether, and in what way, the nurses paid attention to the fact that the patients were women. Nursing care is an important aspect of the rehabilitation of stroke survivors. Little attention has been paid to gender differences in the health care system in general and in the nursing profession in particular, although it is reasonable to think that gender issues may have important implications in the rehabilitation process following a stroke. Design was phenomenological with feminist perspective. The nurses were interviewed in-depth. In the data analysing process we were inspired by Giorgi's phenomenological method. The nurses were focusing primarily on functional and practical aspects of the women's situation. They perceived the rehabilitation process predominately from a professional rather than the patient point of view, and from a non-conscious and primarily gender-neutral perspective. The results indicate that the nurses perceived nursing care primarily in terms of practical actions to promote the body's functional and practical abilities. Little attention was directed to the stroke survivors' experiences of their life body, nor to the fact that the patients were women. In order to promote care from the perspective of the female stroke survivors, we believe it is necessary to attend to the life experiences of the patient, which also mandates paying attention to how gender has an impact on their diseased bodies, every day life, values and preferences in the situation.
