Using an integrated competence model to evaluate a health visitor cascade training programme for the Family Resilience Assessment Instrument and Tool (FRAIT).

This paper reports on an evaluation of health visitor trainers' experience of a cascade training programme delivered in Wales, UK. Health visitors used Driscoll's model (What, So What, Now What) to organise their feedback and an integrated competence model developed by Weeks et al. was used to analyse the feedback via category analysis of free text. As well as feedback on the logistics of running the training, the evaluation allowed for cognitive and functional competence to be identified along with personal and meta competence. There was limited scope for identifying ethical competence in the Health Visitor cascade trainer feedback. Suggestions are made for how this may be addressed.

Developing a family resilience assessment tool for health visiting/public health nursing practice using virtual commissioning, high-fidelity simulation and focus groups.

UK public health nurse assessment of family resilience is a necessary component of monitoring family health and children's development and identifying areas for change. This research was part of an exploration of Welsh public health nurses' understanding of 'family resilience' as a concept underpinning their practice. From it, the Family Resilience Assessment Instrument Tool (FRAITTM www.frait.wales/) was developed for public health nurses use. We report on a virtual commissioning process using focus groups and an immersive simulation suite to test a FRAIT prototype in a safe environment before field testing. Virtual commissioning design: Hydra-Minerva Immersive Simulation Suite - individual public health nurses presented with a multi-media scenario as they used the prototype FRAIT. Follow-up focus groups for usability insights before field testing. Virtual commissioning raised real-world issues which public health nurses discussed in focus groups. Issues were scoring, absence of information, focusing on family resilience, identifying adults caring for children, potential for use, identifying need and monitoring change, potential impact of using FRAIT and fitting it to everyday practice. Prototype testing like this allowed us to fine tune the FRAIT for field testing.

Developing the health visitor concept of family resilience in Wales using Group Concept Mapping.

INTRODUCTION: A health visitor's ability to assess and analyse aspects of family resilience in daily practice is essential to enable practitioners to support families and facilitate positive lifestyle choices, and improve child health and developmental outcomes. The purpose of this research was to undertake an in-depth exploration of the concept of family resilience as understood by health visitors in Wales and to develop a concept map. This knowledge has been used to develop the Family Resilience Assessment Instrument Tool (FRAIT). This is a standardised form of assessment, measuring instrument, guidance, training package and community of practice for use in health visitor daily practice. This article presents the first stage of the FRAIT research study, that of identifying the clusters within the concept map of what health visitors perceive as 'family resilience'. METHODS: A structured Group Concept Mapping (GCM) methodology using Concept Systems' Global Max online software was used to gain a consensus of the understanding of the concept of family resilience from 62 invited health visitors practising across Wales. This is an integrated qualitative and quantitative approach to brainstorming, idea synthesis, idea sorting, idea rating and group analysis. GCM has six clear steps, with four steps described in the method: 'preparing for concept mapping', 'generating ideas', 'structuring the statements' and 'concept mapping analysis'. Steps 5 and 6, 'interpreting the maps' and 'utilisation', are considered in the results section. RESULTS: Use of multi-dimensional scaling and hierarchical cluster analysis enabled point, cluster, rating and pattern matching maps to be presented to the study group. These were then interpreted, understood and consensus gained on how the concept of family resilience was constructed from both the study group and the health visitor participants. Family resilience understood by health visitors in Wales comprises five clusters: 'family health', 'responsive parenting', 'engagement', 'family support' and 'socioeconomic factors'. Each of the clusters has an identified number of underpinning statements from a total number of 117 statements. CONCLUSION: Family resilience as understood by health visitors is a multidimensional concept. Using online software such as Concept Systems' Global Max enabled health visitors working across Wales to achieve a consensus and generate the data in preparation for building FRAIT for use in their daily practice as required by Welsh Government policy.

Ischemic preconditioning at a remote site prevents acute kidney injury in patients following cardiac surgery.

Acute kidney injury, a common complication of cardiac surgery with cardiopulmonary bypass, is associated with increased morbidity and mortality. Ischemic preconditioning at a remote site mitigates ischemia-reperfusion injury and may prevent acute kidney injury after cardiac surgery, thus providing clinical benefit. To further study this, we enrolled 120 adult patients undergoing elective cardiac surgery for whom cardiopulmonary bypass was anticipated in a randomized, single-blind, and controlled pilot trial. Patients were stratified for the type of surgery and equally assigned to a control group or to receive remote ischemic preconditioning by an automated thigh tourniquet consisting of three 5-min intervals of lower extremity ischemia separated by 5-min intervals of reperfusion. The primary end point was acute kidney injury defined as an elevation of serum creatinine of ≥0.3 mg/dl or ≥50% within 48 h after surgery. Fifty-nine patients in each group were analyzed on an intention-to-treat basis. Acute kidney injury occurred in 12 remote ischemic preconditioned and 28 control patients, reflecting an absolute risk reduction of 0.27 and a significantly reduced relative risk due to preconditioning of 0.43. Hence, remote ischemic preconditioning prevents acute kidney injury in patients undergoing cardiopulmonary bypass-assisted cardiac surgery.

Effects of combination tocopherols and alpha lipoic acid therapy on oxidative stress and inflammatory biomarkers in chronic kidney disease.

OBJECTIVE: Although increased oxidative stress and inflammation are highly prevalent in chronic kidney disease (CKD), few studies have investigated whether oral antioxidant therapy can alter markers of inflammation or oxidative stress in patients with CKD. The purpose of this study was to investigate whether a combination of mixed tocopherols and alpha lipoic acid (ALA) would alter biomarkers of oxidative stress and inflammation in subjects with stage 3 to 4 CKD. METHODS: This was a prospective, randomized, double-blind, placebo-controlled pilot trial. In all, 62 subjects were enrolled and were randomly assigned to receive a combination of mixed tocopherols 666 IU/day, in addition to ALA 600 mg/day, or their matching placebos for a total of 8 weeks. Plasma F(2)-isoprostane and protein thiol concentration were measured as biomarkers of oxidative stress, and C-reactive protein and interleukin-6 concentration as biomarkers of systemic inflammation. RESULTS: There were no significant differences in demographics, diabetic status, or estimated glomerular filtration rate between study treatment and placebo groups at baseline. Of the 62 randomized subjects, 58 (93%) completed the study protocol. After 2 months of treatment, there were no significant changes in the concentrations of F(2)-isoprostanes, protein thiols, C-reactive protein, and interleukin-6 with respect to treatment with mixed tocopherols and ALA as compared with matching placebos, whether analyzed as intention to treat or as treated. Diabetic status and baseline body mass index did not influence the results. CONCLUSIONS: Combination of oral mixed tocopherols and ALA treatment for 2 months does not influence biomarkers of oxidative stress and inflammation in patients with stage 3 to 4 CKD.

Gamma-tocopherol and docosahexaenoic acid decrease inflammation in dialysis patients.

OBJECTIVE: Increased cardiovascular risk in hemodialysis patients may be related to augmented oxidative stress and inflammation, for which no proven beneficial therapies are available. STUDY DESIGN: We examined the effects of gamma tocopherol and docosahexaenoic acid (DHA) administration on inflammation and oxidative stress markers in hemodialysis patients in a randomized, double-blinded, placebo-controlled, clinical trial. Active treatment consisted of capsules containing gamma tocopherol (308 mg) and DHA (800 mg). SETTING: Outpatient dialysis center. PATIENTS: Seventy maintenance hemodialysis patients. MAIN OUTCOME MEASURES: Plasma concentrations of interleukin-6 (IL-6) and protein carbonyl content were determined by enzyme-linked immunosorbant assay. C-reactive protein was measured by nephelometry. The F(2) isoprostanes were measured by gas chromatography-mass spectrometry. Erythrocyte DHA content was measured by gas chromatography. RESULTS: Sixty-three patients were enrolled, and 57 completed the study. No serious adverse events were attributed to either active treatment or placebo. In the treatment group, but not in the placebo group, there were significant decreases in IL-6 (21.4 +/- 3.5 to 16.8 +/- 3.7 pg/mL), white blood cell (WBC) count (7.4 +/- 0.3 to 6.9 +/- 0.4 10(3)/microL), and neutrophil fraction of WBCs (4.8 +/- 0.3 to 4.4 +/- 0.3 10(3)/microL), at P < .05 for all. There were no significant changes in plasma concentrations of CRP, F(2) isoprostanes, or carbonyls in either group. CONCLUSION: Thus, gamma tocopherol and DHA are well-tolerated and reduce selected biomarkers of inflammation in hemodialysis patients. Larger randomized, clinical trials will be required to determine if gamma tocopherol and DHA can reduce cardiovascular complications in hemodialysis patients.

Linkage of hypoalbuminemia, inflammation, and oxidative stress in patients receiving maintenance hemodialysis therapy.

BACKGROUND: Hypoalbuminemia is a powerful predictor of cardiovascular mortality in maintenance hemodialysis patients. Increased biomarkers of acute-phase inflammation and oxidative stress are highly prevalent and also correlate with cardiovascular morbidity and mortality. The extent to which hypoalbuminemia, biomarkers of inflammation, and biomarkers of oxidative stress are linked in this patient population is unknown. We hypothesized that a high proportion of hypoalbuminemic hemodialysis patients also would manifest increased levels of biomarkers of inflammation and oxidative stress. METHODS: We surveyed 600 maintenance hemodialysis patients and identified 18 severely hypoalbuminemic patients (serum albumin level < 3.2 g/dL [32 g/L]) without recent infection or hospitalization. We then identified 18 age-, race-, sex-, and diabetes-matched normoalbuminemic hemodialysis patients, as well as 18 age-, race-, sex-, and diabetes-matched healthy subjects, for cohort comparison. Measurements of plasma interleukin-6 (IL-6) levels, plasma protein reduced thiol content, plasma protein carbonyl content, and plasma free F2-isoprostane levels, as well as serum concentrations of C-reactive protein (CRP) and prealbumin, were performed for study purposes. RESULTS: Levels of serum CRP, IL-6, plasma protein thiol oxidation, and protein carbonyl formation were significantly elevated in both hypoalbuminemic and normoalbuminemic hemodialysis patients compared with healthy subjects and also were significantly different in hypoalbuminemic maintenance dialysis patients compared with normoalbuminemic hemodialysis patients. Prealbumin levels were significantly lower in hypoalbuminemic hemodialysis patients than in other groups. CONCLUSION: There is a high prevalence of inflammation and oxidative stress in the maintenance hemodialysis population. Levels of inflammatory and oxidative stress biomarkers are increased further in hypoalbuminemic compared with normoalbuminemic dialysis patients. Hypoalbuminemia, acute-phase inflammation, and oxidative stress may act synergistically to increase cardiovascular morbidity and mortality risk in maintenance hemodialysis patients.

Alpha and gamma tocopherol metabolism in healthy subjects and patients with end-stage renal disease.

BACKGROUND: The metabolism of alpha and gamma tocopherol, the major components of vitamin E, have not been studied in uremic patients. The major pathway of tocopherol metabolism is via phytyl side chain oxidation, leaving carboxyethyl-hydroxychromans (CEHC) as metabolites. Alpha and gamma CEHC are water soluble, renally excreted, with known potent anti-inflammatory and antioxidative properties. METHODS: We examined serum alpha and gamma tocopherol and respective CEHC concentrations in 15 healthy subjects and 15 chronic hemodialysis patients. RESULTS: Serum alpha tocopherol levels were similar in hemodialysis patients (12.03 +/- 1.34 microg/mL) and healthy subjects (11.21 +/- 0.20 microg/mL), while serum gamma tocopherol levels were significantly greater in hemodialysis patients (3.17 +/- 0.37 microg/mL) compared to healthy subjects (1.08 +/- 0.06 microg/mL, P < 0.0001). Serum alpha and gamma CEHC levels were tenfold and sixfold higher in hemodialysis patients compared to healthy subjects, respectively (both P < 0.0001). Serum alpha and gamma tocopherol levels and CEHC metabolites were also measured after supplementation of alpha- or gamma-enriched mixed tocopherols in both hemodialysis patients and healthy subjects. Tocopherol administration resulted in modest or nonsignificant changes in serum tocopherol concentrations, while markedly increasing serum CEHC concentrations in both healthy subjects and hemodialysis patients. Hemodialysis resulted in no change in the serum alpha or gamma tocopherol concentrations while decreasing serum alpha CEHC and gamma CEHC levels by 63% and 53%, respectively (both P = 0.001 versus predialysis). Fourteen-day administration of gamma-enriched but not alpha tocopherols lowered median C-reactive protein (CRP) significantly in hemodialysis patients (4.4 to 2.1 mg/L, P < 0.02). CONCLUSION: First, serum alpha and gamma CEHC accumulate in uremic patients compared to healthy subjects; second, supplementation with tocopherols dramatically increases serum CEHC levels in both healthy subjects and hemodialysis patients; and, finally, CEHC accumulation may mediate anti-inflammatory and antioxidative effects of tocopherols in hemodialysis patients.
