- Purpose: To explore and compare cancer patients' perceptions on the quality of nursing care in four European countries. Methods: Data were collected in Cyprus, Finland, Greece and Sweden. The sample comprised 596 hospitalized cancer patients. The quality of nursing care was measured using the "Oncology Patients' Perceptions of the Quality of Nursing Care Scale" (OPPQNCS). Patient characteristics were also collected. Analysis of variance was used to examine the effects of country on the perceptions of the quality of nursing care. Results: Patients' age ranged from 18 to 86 years, and 58% were male. The comparison of cancer patients' perceptions regarding the quality of nursing care between the four countries showed a statistically significant difference in the total OPPQNCS scores (p <0.001) as well as in the subscales responsiveness (p <0.001), individualization (p<0.001), co ordination (p<0.001) and proficiency (p<0.001). The Cronbach's alpha coefficient for the OPPQNCS ranged between 0.89 and 0.95. A multivariate analysis of variance for the OPPQNCS controlled by respondents' demographic characteristics revealed that only the patient's country was significantly related with the patients' perceptions of quality care. Conclusion: Quality of nursing care as perceived by cancer patients was high, but differed between the four countries. The impact of the clinical status of cancer patients on the quality of nursing care and managerial factors such as staffing/nursing care delivery models that influence the ability of nurses to offer high quality care should also be explored by more focused studies.

- A short peripheral intravenous catheter or cannula (PIVC) is frequently used to deliver chemotherapy in oncology practice. Although safe and easy to insert, PIVCs do fail, leading to personal discomfort for patients and adding substantially to treatment costs. As the procedure of peripheral catheterization is invasive, there is a need for greater consistency in the choice, insertion and management of short PIVCs, particularly in the oncology setting where there is a growing trend for patients to receive many different courses of IV treatment over a number of years, sometimes with only short remissions. This article reviews best practice with respect to PIVCs in cancer patients and considers the necessity for bundling these actions. Two care bundles, addressing both insertion and ongoing care and maintenance, are proposed. These have the potential to improve outcomes with the use of short PIVCs for vascular access in oncology practice.

- Background: Providing high quality nursing care for patients with malignancies is complex and driven by many factors. Many of the associations between nursing care quality, trust, health status and individualized care remain obscure. Objective: To empirically test a model of association linking hospitalized cancer patients' health status, nursing care quality, perceived individuality in care and trust in nurses. Design: A cross-sectional, exploratory and correlational study design was used. Settings: This multi-site study was conducted in cancer care clinics, in-patient wards of five tertiary care hospitals in Cyprus, Finland, Greece and Sweden. Sample: Out of 876 hospitalized patients with a confirmed histopathological diagnosis of cancer approached to participate in the study in consecutive order, 599 (response rate 68%) agreed to participate and the data from 590 were used for path analysis. Methods: Data were collected in 2012-2013 with the Individualized Care Scale-Patient (ICS-Patient), the Oncology Patients' Perceptions of Quality Nursing Care Scale (OPPQNCS), the Euro-Qol (EQ-5D-3L) and the Trust in Nurses Scale. Data were analysed statistically using descriptive and inferential statistics. Mplus version 7.11 was used to determine the best Trust model with path analysis. Results: Although the model fit indices suggested that the hypothesized model did not perfectly to the data, a slightly modified model which includes the reciprocal path between individualized care and nursing care quality demonstrated a good fit. Conclusion: A model of trust in nurses was" developed. Health status, individualized care, and nursing care quality were found to be associated with trust. The model highlights the complexity of caring for cancer patients. Trust in nurses is influenced by the provision of individualized care. Generating and promoting trust requires interventions, which promote nursing care quality, individuality and patients' health status.

- Tardigrades are highly tolerant to desiccation and ionizing radiation but the mechanisms of this tolerance are not well understood. In this paper, we report studies on dose responses of adults and eggs of the tardigrade Hypsibius dujardini exposed to gamma radiation. In adults the LD50/48h for survival was estimated at similar to 4200 Gy, and doses higher than 100 Gy reduced both fertility and hatchability of laid eggs drastically. We also evaluated the effect of radiation (doses 50 Gy, 200 Gy, 500 Gy) on eggs in the early and late embryonic stage of development, and observed a reduced hatchability in the early stage, while no effect was found in the late stage of development. Survival of juveniles from irradiated eggs was highly affected by a 500 Gy dose, both in the early and the late stage. Juveniles hatched from eggs irradiated at 50 Gy and 200 Gy developed into adults and produced offspring, but their fertility was reduced compared to the controls. Finally we measured the effect of low temperature during irradiation at 4000 Gy and 4500 Gy on survival in adult tardigrades, and observed a slight delay in the expressed mortality when tardigrades were irradiated on ice. Since H. dujardini is a freshwater tardigrade with lower tolerance to desiccation compared to limno-terrestrial tardigrades, the high radiation tolerance in adults, similar to limno-terrestrial tardigrades, is unexpected and seems to challenge the idea that desiccation and radiation tolerance rely on the same molecular mechanisms. We suggest that the higher radiation tolerance in adults and late stage embryos of H. dujardini (and in other studied tardigrades) compared to early stage embryos may partly be due to limited mitotic activity, since tardigrades have a low degree of somatic cell division (eutely), and dividing cells are known to be more sensitive to radiation.

- BACKGROUND: Cancer screening aims to detect cancer at an asymptomatic stage, although side effects from screening also occur. We investigated the prevalence, longitudinal development, and predictors of psychosocial consequences of false-positive breast cancer screening. METHODS: Three hundred ninety-nine women with false-positive screening mammography responded to the Consequences of Screening-Breast Cancer (COS-BC) questionnaire immediately after a negative diagnosis (free from breast cancer) following recall examination(s) (baseline), and 6 and 12 months later. Age-matched controls (n = 499) with a negative mammogram responded to the COS-BC at the same occasions. Five COS-BC scales (Sense of dejection, Anxiety, Behavioral, Sleep, and Existential values) were used as outcome measures. RESULTS: Women with false-positive mammography had consistently higher prevalence of all five consequences compared with controls (P < 0.001). The prevalences decreased between baseline and 6 months (P < 0.001) but were stable between 6 and 12 months (P ≥ 0.136). Early recall profoundly predicted long-term consequences for all five outcomes (OR, 3.05-10.31), along with dissatisfaction with information at recall (OR, 2.28-2.56), being foreign-born (OR, 2.35-3.71), and lack of social support (OR, 1.13-1.25). CONCLUSION: This 1-year longitudinal study shows that women experience psychosocial consequences of false-positive screening mammography. Early recall should be performed cautiously, and provision of information as well as social support may reduce psychosocial consequences. IMPACT: Although delivery of population-based screening reduces breast cancer mortality, it also raises the issue of its impact on the psychosocial well-being of healthy women. Our findings identify predictors that can be targeted in future efforts to reduce the side effects of mammographic screening.

- We are using the label-free technique of holographic microscopy to analyze cellular parameters including cell number, confluence, cellular volume and area directly in the cell culture environment. We show that death-induced cells can be distinguished from untreated counterparts by the use of holographic microscopy, and we demonstrate its capability for cell death assessment. Morphological analysis of two representative cell lines (L929 and DU145) was performed in the culture flasks without any prior cell detachment. The two cell lines were treated with the anti-tumour agent etoposide for one to three days. Measurements by holographic microscopy showed significant differences in average cell number, confluence, volume and area when comparing etoposide-treated with untreated cells. The cell volume of the treated cell lines was initially increased at early time-points. By time, cells decreased in volume, especially when treated with high doses of etoposide. In conclusion, we have shown that holographic microscopy allows label-free and completely non-invasive morphological measurements of cell growth, viability and death. Future applications could include real-time monitoring of these holographic microscopy parameters in cells in response to clinically relevant compounds.

- Background/Aim: Androgen deprivation therapy is usually in the initial phase a successful treatment for prostate cancer but eventually most patients develop androgen-independent metastatic disease. This study investigated if manganese (Mn) reduces viability of prostate cancer via induction of apoptosis. Materials and Methods: The prostate cancer cell lines PC3, DU145 and LNCaP underwent dose- and time-dependent screening of viability, analyzed by the 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay. Flow cytometry was used for the cell-cycle and apoptosis analyses. Intracellular Mn concentration was measured using inductively coupled plasma-mass spectrometry. Results: At Mn concentrations of 200-1000 µM, the effect on viability was most pronounced in PC3 followed by LNCaP cells. These cell lines also showed higher intracellular concentration of Mn compared to DU145. In all cell lines, Mn increased the proportion of cells arrested in the G0/G1 phase and induced apoptosis. Conclusion: To our knowledge, this is the first report demonstrating Mn as a potential agent in prostate cancer therapy.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Breast cancer (BC) is the most common type of cancer in women worldwide. Post-treatment, patients suffer from side effects and have various rehabilitation needs, which means that individualization is fundamental for optimal rehabilitation. This systematic review (SR) of SRs aims to evaluate the current evidence on rehabilitation interventions in female patients following BC treatment. METHODS: Full-text SRs published in English from 2009 were searched in Embase, PubMed, Cinahl Complete, PsycINFO, AMED, SCOPUS, and Cochrane Library. INCLUSION CRITERIA: SRs of randomized or non-randomized controlled trials investigating the effects of rehabilitation interventions in women following BC treatment. All outcomes were considered. Methodological quality was evaluated using the AMSTAR 2 tool and interrater agreement was evaluated. Out of 1269 citations retrieved, 37 SRs were included. RESULTS: Five rehabilitation areas were identified: exercise and physical activity (PA), complementary and alternative medicine (CAM), yoga, lymphoedema treatment, and psychosocial interventions. The most solid evidence was found in exercise/PA and yoga. Exercise interventions improved outcomes such as shoulder mobility, lymphoedema, pain, fatigue and quality of life (QoL). Effects of yoga were shown on QoL, anxiety, depression, sleep disturbance, fatigue and gastrointestinal symptoms. The effect of CAM was shown on nausea, pain, fatigue, anger and anxiety but these results need to be interpreted with caution because of low methodological quality in included studies in the SRs. Among the lymphoedema treatments, positive effects were seen for resistance training on volume reduction and muscle strength and psychosocial interventions such as cognitive behavioural therapy had positive effects on QoL, anxiety, depression and mood disturbance. CONCLUSIONS: This SR of SRs show solid positive effects of exercise/PA and yoga for women following BC treatment, and provides extended knowledge of the effects of CAM, yoga, lymphoedema treatment and psychosocial interventions. It is evident that more than one intervention could have positive effects on a specific symptom and that the effects depend not only on intervention type but also on how and when the intervention is provided. The results can be used as a foundation for individualized rehabilitation and aid health care professionals in meeting patients' individual needs and preferences. TRIAL REGISTRATION: PROSPERO ( CRD42017060912 ).
