Methodological issues in interviewing families in family nursing research

AIM OF THE STUDY: The aim of this study is to discuss what methodological problems can be met in family research with one family member as an interviewee speaking on behalf of the whole family and, vice versa, what is the meaning of having multiple family members or the whole family unit as informants. BACKGROUND: Family nursing research is part of multidisciplinary research with families. It is a basis for family nursing and contributes to research, especially from the perspective of family welfare and its promotion. Family nursing research generates knowledge concerning families' and family members' wellbeing and experiences and expectations of nursing and health care. METHODS: The examination of methodological problems while pursuing family research is based on two studies conducted in Finland. FINDINGS: Quantitative methods add to the general knowledge of families. Qualitative methods are well suited to the study of family experiences. Family interviews performed for research purposes differ from interviews aiming at caring for families. They aim at obtaining knowledge of families on a general level so as to improve family nursing. Family research has to be looked at as a whole. It faces many challenges such as the definition of the family, gaining access, methods of data collection and data management. CONCLUSIONS: A family is a complex system and research with families need flexible, sensitive and practical methods. Family research should also aim at developing new methods for data collection and analysis.     

Promoting health for families of children with chronic conditions

AIM: This paper reports a study whose aim was to describe how nurses in a paediatric unit promote the health of families of children with chronic conditions during the children's hospitalization. BACKGROUND: It is stressful for a family when a child has a chronic condition and hospitalized. Nurses have the opportunity to promote family health while a child is hospitalized, and previous studies contain a wealth of recommendations on how this should be done. However, there is little research evidence about family care and how nurses promote the health of a family with a chronically ill child. METHODS: Forty nurses who worked in two paediatric units providing care for children with chronic conditions and their families participated in the study. Data were collected in two Finnish hospitals in 2002 using group interviews, and nursing actions were observed in both units for a period of 84 hours. Data analysis was based on the grounded theory method, proceeding to the stage of axial coding. Data were collected until theoretical saturation was reached. FINDINGS: Family care was based on three distinctive strategies. Nurses used a systematic, selective or situation-specific strategy while promoting family health during a child's hospitalization. CONCLUSIONS: The findings indicate that nurses used different strategies while promoting family health during a child's hospitalization. The systematic way of working with families identified in the study seems a useful strategy. All three strategies of family nursing described here should be tested in other paediatric wards and in other geographical locations.     

Further testing of a family nursing instrument (FAFHES)

BACKGROUND: Cardiac illness in one family member affects the well-being and health of the whole family. When a family member falls ill, life may change for the whole family in many ways. Family members expect nursing staff to provide more support when their family situation changes. OBJECTIVES: To describe further development and testing of a family nursing instrument for assessing the association between social support for the family of an adult cardiac patient and family functioning and perceived family health. SETTINGS: The study was conducted in two university hospitals and in two central hospitals in Finland. METHODS AND PARTICIPANTS: Questionnaires were given to family members of heart patients. Patients themselves defined who their closest adult relative was. Data were collected from family members of 509 heart patients. RESULTS: Good internal reliability in this further testing of a new instrument was demonstrated. Principal component analysis (PCA) with varimax rotation was performed in each of the three total scales: family functioning, family health and social support. PCA supported the previously proposed theoretical framework. A final scale consisted of 62 items. All the total scales and subscales had acceptable validity and reliability, alpha coefficients ranged from .76 to .98. CONCLUSIONS: The Family Functioning, Health and Social Support (FAFHES) provides a reliable and valid instrument when the investigator wishes to measure social support associated with family functioning and the health of families of heart patients.     

A prefrontal non-opioid mechanism in placebo analgesia

Behavioral studies have suggested that placebo analgesia is partly mediated by the endogenous opioid system. Expanding on these results we have shown that the opioid-receptor-rich rostral anterior cingulate cortex (rACC) is activated in both placebo and opioid analgesia. However, there are also differences between the two treatments. While opioids have direct pharmacological effects, acting on the descending pain inhibitory system, placebo analgesia depends on neocortical top-down mechanisms. An important difference may be that expectations are met to a lesser extent in placebo treatment as compared with a specific treatment, yielding a larger error signal. As these processes previously have been shown to influence other types of perceptual experiences, we hypothesized that they also may drive placebo analgesia. Imaging studies suggest that lateral orbitofrontal cortex (lObfc) and ventrolateral prefrontal cortex (vlPFC) are involved in processing expectation and error signals. We re-analyzed two independent functional imaging experiments related to placebo analgesia and emotional placebo to probe for a differential processing in these regions during placebo treatment vs. opioid treatment and to test if this activity is associated with the placebo response. In the first dataset lObfc and vlPFC showed an enhanced activation in placebo analgesia vs. opioid analgesia. Furthermore, the rACC activity co-varied with the prefrontal regions in the placebo condition specifically. A similar correlation between rACC and vlPFC was reproduced in another dataset involving emotional placebo and correlated with the degree of the placebo effect. Our results thus support that placebo is different from specific treatment with a prefrontal top-down influence on rACC.     

Infrequent isolation of multiresistant Acinetobacter baumannii from the staff tending a colonized patient with severe burns.

A patient with severe burns who was colonized by multiresistant Acinetobacter baumannii was cared for in contact isolation by staff intensively trained on hospital hygiene. Of the 1,907 postexposure cultures from the staff and 425 environmental samples, only 0.7% and 4%, respectively, yielded this microorganism. These data show that strict hygienic measures may limit staff colonization and contamination of the environment byA baumannii.     

How palliative care of cancer patients is organised between a university hospital and primary care in Finland

The aim of this study was to find out how palliative care is organised between the Helsinki University Central Hospital (University Hospital) and primary care. The study consisted of 102 patients whose oncological treatment was terminated and the responsibility of palliative care was transferred to primary care. The patients were interviewed by phone using a structured questionnaire. Another questionnaire form was sent to the primary care physicians. Half of the patients were treated in more than one primary care unit. One third of the outpatients were unaware who was responsible for the care. Most of the patients wanted to be at home but this was achieved in less than half of the cases. Most patients were symptomatic while leaving the University Hospital and no improvement was seen thereafter. Every third patient reported of poor quality of palliative care in the primary care. Also the physicians reported a need for training in palliative care.     

Boron Neutron Capture Therapy of Brain Tumors: Clinical Trials at the Finnish Facility Using Boronophenylalanine

Two clinical trials are currently running at the Finnish dedicated boron neutron capture therapy (BNCT) facility. Between May 1999 and December 2001, 18 patients with supratentorial glioblastoma were treated with boronophenylalanine (BPA)-based BNCT within a context of a prospective clinical trial (protocol P-01). All patients underwent prior surgery, but none had received conventional radiotherapy or cancer chemotherapy before BNCT. BPA-fructose was given as 2-h infusion at BPA-dosages ranging from 290 to 400mg/kg prior to neutron beam irradiation, which was given as a single fraction from two fields. The average planning target volume dose ranged from 30 to 61Gy (W), and the average normal brain dose from 3 to 6Gy (W). The treatment was generally well tolerated, and none of the patients have died during the first months following BNCT. The estimated 1-year overall survival is 61%. In another trial (protocol P-03), three patients with recurring or progressing glioblastoma following surgery and conventional cranial radiotherapy to 50–60Gy, were treated with BPA-based BNCT using the BPA dosage of 290mg/kg. The average planning target dose in these patients was 25–29Gy (W), and the average whole brain dose 2–3Gy (W). All three patients tolerated brain reirradiation with BNCT, and none died during the first three months following BNCT. We conclude that BPA-based BNCT has been relatively well tolerated both in previously irradiated and unirradiated glioblastoma patients. Efficacy comparisons with conventional photon radiation are difficult due to patient selection and confounding factors such as other treatments given, but the results support continuation of clinical research on BPA-based BNCT.     

Machine-learning-derived classifier predicts absence of persistent pain after breast cancer surgery with high accuracy

Purpose

To define the mutational spectrum of several candidate gene mutations in Israeli male breast cancer cases.

Methods

MBC cases counselled at the Oncogenetics unit, Sheba Medical Center from January 1998 to June 2017 were included. Relevant clinical and oncological data and cancer phenotype were retrieved. All participants were genotyped for the predominant Jewish BRCA1 and BRCA2 germline mutations using a chip-based assay. Those who tested negative were further genotyped for three recurring mutations in CHEK2 (c.1100delC, p.S428F, p.I157T), and single mutations in the FANCM (c.5791C>T), and RAD51D (c.556C>T) genes, by direct sequencing. The ethics committee approved the study.

Results

Overall, 61 MBC were identified and genotyped, 41 (67.2%) were Ashkenazim, age at diagnosis was 58.1?±?12.6 years, and 31 (50.8%) had a family history of cancer. Of genotyped individuals, one (1.6%) harboured the 185delAG* BRCA1 mutation, 7 (11.4%) the 6174delT*BRCA2 mutation and 2 (3.2%) other recurring mutations in BRCA2 (overall 10/61–16.4% BRCA1/BRCA2 mutation carriers). Of BRCA-negative cases, 3/51 (5.9%) carried the p.S428F *CHEK2 mutation. None was a carrier of the other genotyped mutations in CHEK2, FANCM or RAD51D.

Conclusion

BRCA1, BRCA2 and CHEK2 germline mutations contribute to inherited predisposition to MBC in Israel.

     

High-resolution genomic and expression profiling reveals 105 putative amplification target genes in pancreatic cancer

Comparative genomic hybridization (CGH) studies have provided a wealth of information on common copy number aberrations in pancreatic cancer, but the genes affected by these aberrations are largely unknown. To identify putative amplification target genes in pancreatic cancer, we performed a parallel copy number and expression survey in 13 pancreatic cancer cell lines using a 12,232-clone cDNA microarray, providing an average resolution of 300 kb throughout the human genome. CGH on cDNA microarray allowed highly accurate mapping of copy number increases and resulted in identification of 24 independent amplicons, ranging in size from 130 kb to 11 Mb. Statistical evaluation of gene copy number and expression data across all 13 cell lines revealed a set of 105 genes whose elevated expression levels were directly attributable to increased copy number. These included genes previously reported to be amplified in cancer as well as several novel targets for copy number alterations, such as p21-activated kinase 4 (PAK4), which was previously shown to be involved in cell migration, cell adhesion, and anchorage-independent growth. In conclusion, our results implicate a set of 105 genes that is likely to be actively involved in the development and progression of pancreatic cancer.
