[Experiences of patients and family members during the stay on a nursing unit]

In 2004, the university hospital of Berne ran a pilot project with a Nursing Unit (NU). In this unit patients who no longer needed a close surveillance by physicians were cared for. They needed primarily complex professional nursing care which could not be provided by other hospitals, nursing homes, home care or family members. The nurses were responsible for the coordination of care. This qualitative study investigated experiences of patients and family members with the care concept of the NU. Thematically focused interviews were conducted with nine patients and five family members. Qualitative content analysis was used for data analysis. Results show that patients and family members mostly accepted the new care concept. They positively experienced the quiet and restful atmosphere, the patient-centred and continuous care by competent nurses, the education and the discharge planning. Some study participants reported missing information at the time of their transfer to the NU, insufficient assessments or unsuitable educational scripts. The study provides evidence to positive effects of a patient-centred care approach.

[Swiss Research Agenda for Nursing (SRAN): the development of an agenda for clinical nursing research in Switzerland]

In many Anglo-Saxon and North European countries nursing research agendas have been developed to address priorities in nursing research in accordance with a nationally defined health policy. In Switzerland, due to lack of a nationwide governmental health policy, co-ordination of nursing research so far was scarce. The "Swiss Research Agenda for Nursing (SRAN)" project developed an agenda for clinical nursing research between 2005 and 2007. Based on literature reviews, expert panels and a national survey a project team formulated an agenda which passed a consensus conference. The agenda recommends aspects that should lead research and defines seven research priorities for nursing in Switzerland for the time between 2007 and 2017. Nursing research should prioritize to investigate 1) the effectiveness of nursing interventions; 2) the influences of service adaptations in a changing health care system; 3) the phenomena in patients requiring nursing care; 4) the influence of the work environment on the quality of nursing care; 5) the functioning of family and social systems; 6) varieties of life circumstances and their integration; and 7) the implementation of ethical principles in nursing. Written in German and French, the Swiss Research Agenda for Nursing for the first time formulates priorities for nursing research in Switzerland and can be used for strategic discussions. As a next step, the development of an action plan to enhance nursing research will take place in Switzerland.

Experimentally induced cam impingement in the sheep hip

Sheep hips have a natural non-spherical femoral head similar to a cam-type deformity in human beings. By performing an intertrochanteric varus osteotomy, cam-type femoro-acetabular impingement (FAI) during flexion can be created. We tested the hypotheses that macroscopic lesions of the articular cartilage and an increased Mankin score (MS) can be reproduced by an experimentally induced cam-type FAI in this ovine in vivo model. Furthermore, we hypothesized that the MS increases with longer ambulatory periods. Sixteen sheep underwent unilateral intertrochanteric varus osteotomy of the hip with the non-operated hip as a control. Four sheep were sacrificed after 14, 22, 30, and 38-weeks postoperatively. We evaluated macroscopic chondrolabral alterations, and recorded the MS, based on histochemical staining, for each ambulatory period. A significantly higher prevalence of macroscopic chondrolabral lesions was found in the impingement zone of the operated hips. The MS was significantly higher in the acetabular/femoral cartilage of the operated hips. Furthermore, these scores increased as the length of the ambulatory period increased. Cam-type FAI can be induced in an ovine in vivo model. Localized chondrolabral degeneration of the hip, similar to that seen in humans (Tannast et al., Clin Orthop Relat Res 2008; 466: 273-280; Beck et al., J Bone Joint Surg Br 2005; 87: 1012-1018), can be reproduced. This experimental sheep model can be used to study cam-type FAI.

Early gene expression analysis in 9L orthotopic tumor-bearing rats identifies immune modulation in molecular response to synchrotron microbeam radiation therapy

Synchrotron Microbeam Radiation Therapy (MRT) relies on the spatial fractionation of the synchrotron photon beam into parallel micro-beams applying several hundred of grays in their paths. Several works have reported the therapeutic interest of the radiotherapy modality at preclinical level, but biological mechanisms responsible for the described efficacy are not fully understood to date. The aim of this study was to identify the early transcriptomic responses of normal brain and glioma tissue in rats after MRT irradiation (400Gy). The transcriptomic analysis of similarly irradiated normal brain and tumor tissues was performed 6 hours after irradiation of 9 L orthotopically tumor-bearing rats. Pangenomic analysis revealed 1012 overexpressed and 497 repressed genes in the irradiated contralateral normal tissue and 344 induced and 210 repressed genes in tumor tissue. These genes were grouped in a total of 135 canonical pathways. More than half were common to both tissues with a predominance for immunity or inflammation (64 and 67% of genes for normal and tumor tissues, respectively). Several pathways involving HMGB1, toll-like receptors, C-type lectins and CD36 may serve as a link between biochemical changes triggered by irradiation and inflammation and immunological challenge. Most immune cell populations were involved: macrophages, dendritic cells, natural killer, T and B lymphocytes. Among them, our results highlighted the involvement of Th17 cell population, recently described in tumor. The immune response was regulated by a large network of mediators comprising growth factors, cytokines, lymphokines. In conclusion, early response to MRT is mainly based on inflammation and immunity which appear therefore as major contributors to MRT efficacy.

Between anxiety and hope: the experiences of women with vulval intraepithelial neoplasia during their illness trajectory - a qualitative approach

The vulvar intraepithelial neoplasia (VIN) is a rare chronic skin condition that may progress to an invasive carcinoma of the vulva. Major issues affecting women's health were occurring symptoms, negative influences on sexuality, uncertainty concerning the illness progression and changes in the body image. Despite this, there is little known about the lived experiences of the illness trajectory. Therefore, the aim of this study was to describe the experiences of women with VIN during the illness trajectory. In a secondary data analysis of the foregoing qualitative study we analysed eight narrative interviews with women with VIN by using thematic analysis in combination with critical hermeneutics. Central for these women during their course of illness was a sense of "Hope and Fear". This constitutive pattern reflects the fear of recurrence but also the trust in healing. The eight narratives showed women's experiences during their course of illness occurred in five phases: "there is something unknown"; "one knows, what IT is"; "IT is treated and should heal"; "IT has effects on daily life"; "meanwhile it works". Women's experiences were particularly influenced by the feeling of "embarrassment" and by "dealing with professionals". Current care seems to lack adequate support for women with VIN to manage these phases. We suggest, based on our study and the international literature, that new models of counselling and providing information need to be developed and evaluated.

Excited-State Structure, Vibrations, and Nonradiative Relaxation of Jet-Cooled 5-Fluorocytosine

The S0 → S1 vibronic spectrum and S1 state nonradiative relaxation of jet-cooled keto-amino 5-fluorocytosine (5FCyt) are investigated by two-color resonant two-photon ionization spectroscopy at 0.3 and 0.05 cm–1 resolution. The 000 rotational band contour is polarized in-plane, implying that the electronic transition is 1ππ*. The electronic transition dipole moment orientation and the changes of rotational constants agree closely with the SCS-CC2 calculated values for the 1ππ* (S1) transition of 5FCyt. The spectral region from 0 to 300 cm–1 is dominated by overtone and combination bands of the out-of-plane ν1′ (boat), ν2′ (butterfly), and ν3′ (HN–C6H twist) vibrations, implying that the pyrimidinone frame is distorted out-of-plane by the 1ππ* excitation, in agreement with SCS-CC2 calculations. The number of vibronic bands rises strongly around +350 cm–1; this is attributed to the 1ππ* state barrier to planarity that corresponds to the central maximum of the double-minimum out-of-plane vibrational potentials along the ν1′, ν2′, and ν3′ coordinates, which gives rise to a high density of vibronic excitations. At +1200 cm–1, rapid nonradiative relaxation (knr ≥ 1012 s–1) sets in, which we interpret as the height of the 1ππ* state barrier in front of the lowest S1/S0 conical intersection. This barrier in 5FCyt is 3 times higher than that in cytosine. The lifetimes of the ν′ = 0, 2ν1′, 2ν2′, 2ν1′ + 2ν2′, 4ν2′, and 2ν1′ + 4ν2′ levels are determined from Lorentzian widths fitted to the rotational band contours and are τ ≥ 75 ps for ν′ = 0, decreasing to τ ≥ 55 ps at the 2ν1′ + 4ν2′ level at +234 cm–1. These gas-phase lifetimes are twice those of S1 state cytosine and 10–100 times those of the other canonical nucleobases in the gas phase. On the other hand, the 5FCyt gas-phase lifetime is close to the 73 ps lifetime in room-temperature solvents. This lack of dependence on temperature and on the surrounding medium implies that the 5FCyt nonradiative relaxation from its S1 (1ππ*) state is essentially controlled by the same ∼1200 cm–1 barrier and conical intersection both in the gas phase and in solution.

[Transition - how adolescents with cystic fibrosis their parents experience the change from paediatric to adult care].

BACKGROUND Cystic Fibrosis is the most common autosomal-recessive hereditary disease among white Europeans. The average survival of CF patients has increased to above 40 years and transition from paediatric to adult care has therefore become a significant issue. AIM With this study, experiences of adolescents with CF and their parents with the transition from the paediatric to the adult care were explored. METHODS At a Swiss university CF centre, six adolescents and their mothers were recruited. Twelve narrative interviews were conducted on how the phase of transition was experienced. The transcribed interviews were analysed according to the method of hermeneutic phenomenology. RESULTS Positive and negative experiences with long term routine care in the paediatric service, general themes of adolescence and the quality of the relationship with paediatric doctors influenced the families' experience during transition significantly. For mothers, insensitive information on the CF diagnosis might have influenced the transition experience. The adolescents welcomed an individualized and age appropriate care. Continuity in care, the announcement of, and involvement in the planning of the transfer were of great importance. The families particularly appreciated the timed adaptations of the transfer to individual needs. CONCLUSIONS Flexibility and a strong collaboration between paediatric and adult CF teams are most relevant in the care of families.

What women want: a qualitative study about postnatal midwifery care at home

In Switzerland, decreases in regular hospital treatment after birth are leading increasingly to mother and child being cared for at home by independent midwives. The research herein was carried out in order to understand the needs of mothers in their home once they leave the hospital and what this midwife provided care consists of. In 2008, eight women from central Switzerland were interviewed on two separate occasions after the birth of their child, and the interviews were analysed using content analysing techniques. Mothers explained that they wanted their baby and themselves to be well cared for. They needed rest and support for recuperation and wished to spend quality time with their new family. The midwifes assisted the mothers to fulfil their needs by counselling, by instructing and by giving information, but they rarely encouraged them to be together as a family. The relationship between midwife and mother turned out to be an important support. Mothers were satisfied if mutual trust was built and if the midwife perceived their needs, respected their autonomy and took the time to be with them. Midwives contribute to the basic well-being of families and support women with medical expertise and ongoing care. Furthermore families need support in general household issues so that new mothers can recover sufficiently.
