A combined strength and balance exercise program to decrease falls risk in dialysis patients : a feasibility study

People suffering end-stage kidney disease receiving hemodialysis have a greater risk of falling and suffering debilitating injuries. The purpose of this study was to examine the feasibility and impact of a combined strength and balance exercise intervention on falls risk in hemodialysis patients. Twenty-four adults (mean age = 67.8 yrs) from two Australian outpatient hemodialysis clinics completed the intervention. Falls risk was measured using the Physiological Profile Assessment (PPA). There was a significant reduction in the median overall falls risk z-score from 1.67 to .52 (z = -3.11, P<.008; r = .45). Median reaction time improved from .30 to .26 sec (z = -2.86, P<.008; r = .41). A strength and balance intervention to reduce the falls risk for dialysis patients is feasible and may reduce falls risk for at risk patients

Topical arnica and mucopolysaccharide polysulfate (hirudoid) to decrease bruising and pain associated with haemodialysis cannulation - related infiltration: a pilot study

ABSTRACTBackground:&nbsp;Topical treatments such as Arnica cream and mucopolysaccharide polysulfuric acid (contained in Hirudoid&nbsp;cream) have been used to treat the bruising and pain arising from dialysis-related infiltrations.Aim:&nbsp;To undertake a randomised controlled pilot study comparing the efficacy of Arnica and Hirudoid creams in treating&nbsp;bruising and pain following post-needling infiltration.Methods:&nbsp;One dialysis centre of 40 patients over a 12-month period. Following infiltration, and at the five subsequent dialysis&nbsp;treatments, pain was measured using the Abbey pain scale and size of the bruise was recorded.Results:&nbsp;Eleven cases of infiltration were recorded consisting of seven males (64%) and four females (36%) who had a mean age&nbsp;of 78 years (SD=9). Access for eight patients was via arteriovenous fistula and for three patients via arteriovenous graft. Eight&nbsp;patients experienced bruising and two patients reported mild pain post-infiltration but there were no differences found between&nbsp;the effect of Arnica or Hirudoid in treating either symptom.Conclusion:&nbsp;This pilot study was unable to detect any differences in the effect of Arnica and Hirudoid on pain or bruising. The&nbsp;study demonstrated that a larger, multicentre trial would be required to power a study and that a non-interventional control&nbsp;group should be added.</div

A nurse managed kidney disease program in regional and remote Australia

Health services that aim to prevent and manage chronic kidney disease (CKD) in rural and remote Aboriginal communities in Australia, including the Goldfields region of Western Australia (WA), require innovative approaches. Nursing roles can significantly improve access to renal services in rural and remote areas as they are able to address a range of renal health promotion and prevention activities, and provide renal clinical education and support to Aboriginal people. The Goldfields Kidney Disease Nursing Management Program (GKDNMP), funded through the Council of Australian Governments (COAG) National Partnership Agreements, was developed to provide a comprehensive approach to primary health care that incorporates a range of health promotion and disease management activities. In the first year, the program increased home dialysis rates and decreased patient travel due to expanded access to renal care within the region. Context-specific health programs generated in response to local needs can be successful in addressing specific health care challenges in rural and remote health.<br /

Intradialytic Laughter Yoga therapy for haemodialysis patients: a pre-post intervention feasibility study.

BACKGROUND: Laughter Yoga consists of physical exercise, relaxation techniques and simulated vigorous laughter. It has been associated with physical and psychological benefits for people in diverse clinical and non-clinical settings, but has not yet been tested in a haemodialysis setting. The study had three aims: 1) to examine the feasibility of conducting Laughter Yoga for patients with end stage kidney disease in a dialysis setting; 2) to explore the psychological and physiological impact of Laughter Yoga for these patients; and 3) to estimate the sample size required for future research. METHODS: Pre/post intervention feasibility study. Eighteen participants were recruited into the study and Laughter Yoga therapists provided a four week intradialytic program (30-min intervention three times per week). Primary outcomes were psychological items measured at the first and last Laughter Yoga session, including: quality of life; subjective wellbeing; mood; optimism; control; self-esteem; depression, anxiety and stress. Secondary outcomes were: blood pressure, intradialytic hypotensive episodes and lung function (forced expiratory volume). Dialysis nurses exposed to the intervention completed a Laughter Yoga attitudes and perceptions survey (n = 11). Data were analysed using IBM SPSS Statistics v22, including descriptive and inferential statistics, and sample size estimates were calculated using G*Power. RESULTS: One participant withdrew from the study for medical reasons that were unrelated to the study during the first week (94 % retention rate). There were non-significant increases in happiness, mood, and optimism and a decrease in stress. Episodes of intradialytic hypotension decreased from 19 pre and 19 during Laughter Yoga to 4 post Laughter Yoga. There was no change in lung function or blood pressure. All nurses agreed or strongly agreed that Laughter Yoga had a positive impact on patients\u27 mood, it was a feasible intervention and they would recommend Laughter Yoga to their patients. Sample size calculations for future research indicated that a minimum of 207 participants would be required to provide sufficient power to detect change in key psychological variables. CONCLUSIONS: This study provides evidence that Laughter Yoga is a safe, low-intensity form of intradialytic physical activity that can be successfully implemented for patients in dialysis settings. Larger studies are required, however, to determine the effect of Laughter Yoga on key psychological variables.

The impact of an exercise physiologist coordinated resistance exercise program on the physical function of people receiving hemodialysis: a stepped wedge randomised control study

Background:Exercise during hemodialysis treatments improves physical function, markers of cardiovascular disease and quality of life. However, exercise programs are not a part of standard therapy in the vast majority of hemodialysis clinics internationally. Hemodialysis unit-based accredited exercise physiologists may contribute to an increased intradialytic exercise uptake and improved physical function.Methods and design: This is a stepped wedge cluster randomised controlled trial design. A total of 180 participants will be recruited from 15 community satellite hemodialysis clinics in a large metropolitan Australian city. Each clinic will represent a cluster unit. The stepped wedge design will consist of three groups each containing five randomly allocated cluster units, allocated to either 12, 24 or 36 weeks of the intervention. The intervention will consist of an accredited exercise physiologist-coordinated program consisting of six lower body resistance exercises using resistance elastic bands and tubing. The resistance exercises will include leg abduction, plantar flexion, dorsi flexion, straight-leg/bent-knee raise, knee extension and knee flexion. The resistance training will incorporate the principle of progressive overload and completed in a seated position during the first hour of hemodialysis treatment. The primary outcome measure is objective physical function measured by the 30-second sit to stand test. Secondary outcome measures include the 8-foot timed-up-and-go test, the four square step test, quality of life, cost-utility analysis, uptake and involvement in community activity, self-reported falls, fall\u27s confidence, medication use, blood pressure and morbidity (hospital admissions). Discussion: The results of this study are expected to determine the efficacy of an accredited exercise physiologist supervised resistance training on the physical function of people receiving hemodialysis and the cost-utility of exercise physiologists in hemodialysis centres. This may contribute to intradialytic exercise as standard therapy using an exercise physiologist workforce model.</div

Efficacy and cost-effectiveness of an outcall program to reduce carer burden and depression among carers of cancer patients (PROTECT) : rationale and design of a randomized controlled trial

Published: 6 January 2014BACKGROUND: Carers provide extended and often unrecognized support to people with cancer. The aim of this study is to test the hypothesis that excessive carer burden is modifiable through a telephone outcall intervention that includes supportive care, information and referral to appropriate psycho-social services. Secondary aims include estimation of changes in psychological health and quality of life. The study will determine whether the intervention reduces unmet needs among patient dyads. A formal economic program will also be conducted. METHODS/DESIGN: This study is a single-blind, multi-centre, randomized controlled trial to determine the efficacy and cost-efficacy of a telephone outcall program among carers of newly diagnosed cancer patients. A total of 230 carer/patient dyads will be recruited into the study; following written consent, carers will be randomly allocated to either the outcall intervention program (n = 115) or to a minimal outcall / attention control service (n = 115). Carer assessments will occur at baseline, at one and six months post-intervention. The primary outcome is change in carer burden; the secondary outcomes are change in carer depression, quality of life, health literacy and unmet needs. The trial patients will be assessed at baseline and one month post-intervention to determine depression levels and unmet needs. The economic analysis will include perspectives of both the health care sector and broader society and comprise a cost-consequences analysis where all outcomes will be compared to costs. DISCUSSION: This study will contribute to our understanding on the potential impact of a telephone outcall program on carer burden and provide new evidence on an approach for improving the wellbeing of carers.Patricia M Livingston, Richard H Osborne, Mari Botti, Cathy Mihalopoulos, Sean McGuigan, Leila Heckel, Kate Gunn, Jacquie Chirgwin, David M Ashley and Melinda William

Leaves shed light on flowering: (Vegetative growth and control of floral induction in Sorghum bicolor)

Project tests the hypothesis that floral induction and flowering time in Sorghum bicolor L. can be "regulated by in-crop canopy modification", with the result that farmers would be better able to manage their corps to avoid severe crop water stress at flowering

The management of rice grown on raised beds with continuous furrow irrigation

A field experiment compared two rice (Oryza sativa L.) cropping systems: paddy or raised beds with continuous furrow irrigation; and trialled four cultivars: Starbonnet, Lemont, Amaroo and Ceysvoni, and one test line YRL39; that may vary in adaptation to growth on raised beds. The grain yield of rice ranged from 740 to 1250 g/m(2) and was slightly greater in paddy than on raised beds. Although there were early growth responses to fertilizer nitrogen on raised beds, the crop nitrogen content at maturity mostly exceeded 20 g/m(2) in both systems, so nitrogen was unlikely to have limited yield. Ceysvoni yielded best in both systems, a result of good post-anthesis growth and larger grain size, although its whole-grain mill-out percentage was poor relative to the other cultivars. Starbonnet and Lemont yielded poorly on raised beds, associated with too few tillers and too much leaf area. When grown on raised beds all cultivars experienced a delay in anthesis resulting in more tillers, leaf area and dry weight at anthesis, and probably a greater yield potential. The growth of rice after anthesis, however, was similar on raised beds and in paddy, so reductions in harvest index and grain size on raised beds were recorded. The data indicated that water supply was not a major limitation to rice growth on raised beds, but slower crop development was an issue that would affect the use of raised beds in a cropping system, especially in rice-growing areas where temperatures are too cool for optimal crop development.
