How do Thai patients receiving haemodialysis cope with pain?

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

ABSTRACT
Background: 

How do Thai patients adapt to haemodialysis?

The purpose of the current study was to understand the processes Thai people receiving HD used to adapt to CKD and its treatment. Religion, spirituality, social support and self-management were powerful coping strategies. These coping strategies were strongly influenced by Thai culture and other belief systems.

The happiness and subjective well-being of people on haemodialysis

Happiness is a construct that has been gaining more prominence in both social and health research. The measure of happiness, subjective well-being, has not been rigorously explored in the end-stage kidney disease (ESKD) population.

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' 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.

Candida parapsilosis complex water isolates from a haemodialysis unit: biofilm production and in vitro evaluation of the use of clinical antifungals

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)

Occurrence of fungi in water used at a haemodialysis centre

Aims: The aim of this study was to identify and determine the diversity, occurrence and distribution of fungi in water used at a haemodialysis centre.Methods and Results: Samples in the hydraulic circuit for the distribution of the water, dialysate samples and samples of sterilization solution from dialysers were collected over a 3-month period, and 500 ml of each sample was filtered through membranes. All together 116 isolates of fungi were recovered from 89% of all water samples collected inside the haemodialysis unit, with prevalence of moulds in tap water samples and of yeasts in dialysate samples. Fusarium spp. was the most abundant genus found, whereas Candida parapsilosis was the predominant yeast species.Conclusions: This study demonstrated that various fungi were present in the water system. These data suggest the inclusion of the detection and quantification of fungi in the water of haemodialysis.Significance and Impact of the Study: The recovery of fungi from aqueous haemodialysis environments implies a potential risk for haemodialysis patients and indicates the need for continuous maintenance and monitoring. Further studies on fungi in haemodialysis water systems are required to investigate the organism ability to persist, their role in biofilm formation and their clinical significance.

Stpahylococcus aureus biofilms on central venous haemodialysis catheters

As infecções devido a biofilmes bacterianos são comuns em pacientes sob tratamento em hemodiálise. Neste estudo, 16 pacientes (7 homens, 9 mulheres, de 22 a 81 anos, média 50 anos de idade), com um total de 25 cateteres de hemodiálise (3 de triplo-lúmen e 22 de duplo-lúmen) de poliuretano inseridos em veia subclávia foram estudados. Os cateteres permaneceram no local de 3 a 91 dias (média de 47 dias). Os cateteres foram removidos devido ao: mau funcionamento (44%), suspeita de infecção relacionada ao cateter (20%), viabilidade de um acesso permanente (16%), remoção acidental (12%), sinais e sintomas de infecção no local da inserção do cateter (4%) e contaminação exógena (4%). Culturas positivas de ponta foram observadas em sete cateteres (28%), concomitantemente com três culturas positivas de sangue. Das culturas de sangue foram identificados Staphylococcus aureus (12%) e de uma das conexões foi isolado S. aureus. Biofilmes foram observados sobre todas as pontas de cateteres. Os S. aureus isolados do sangue e cateter (ponta e conexão) eram resistentes a pencilina e sensíveis a azitromicina, ciprofloxacina, clindamicina, cloranfenicol, gentamicina, oxacilina, rifampicina, sulfametoxazole, tetraciclina e vancomicina. As cepas de S. aureus isoladas de sangue, ponta de cateter e conexão foram consideradas idênticas devido à coincidência do perfil de sensibilidade. E similaridade genética, avaliada por meio de ribotipagem.

Functional independence in patients with chronic kidney disease being treated with haemodialysis

Purpose: This study has described and analysed the functional independence of the patients served in the haemodialysis services of a countryside town in the State of Sao Paulo, Brazil, using the Functional Independence Measure (FIM). Method: The population considered was that of 214 patients being treated with haemodialysis, assessed in 2011, by means of a social, demographic and clinical report, a Mini-Mental State Examination (MMSE) and also the FIM. Results: The mean age of the population under study was 58.01 years, while the mean FIM point score was 118.38 points, showing a level of complete or modified independence within this population. Even though the level of dependence found has been low, this can be highlighted, within the locomotion domain, in the activity of going up and down stairs (10.28%). Age, complications arising from haemodialysis, and comorbidities show a negative correlation with FIM. Conclusion: Awareness of the level of functional independence of the patients being subjected to treatment with haemodialysis is essential in order to back up intervention for the improvement of nursing assistance provided to this population.

Hepatitis B virus infection in Haemodialysis Centres from Santa Catarina State, Southern Brazil. Predictive risk factors for infection and molecular epidemiology

Abstract Background Patients under haemodialysis are considered at high risk to acquire hepatitis B virus (HBV) infection. Since few data are reported from Brazil, our aim was to assess the frequency and risk factors for HBV infection in haemodialysis patients from 22 Dialysis Centres from Santa Catarina State, south of Brazil. Methods This study includes 813 patients, 149 haemodialysis workers and 772 healthy controls matched by sex and age. Serum samples were assayed for HBV markers and viraemia was detected by nested PCR. HBV was genotyped by partial S gene sequencing. Univariate and multivariate statistical analyses with stepwise logistic regression analysis were carried out to analyse the relationship between HBV infection and the characteristics of patients and their Dialysis Units. Results Frequency of HBV infection was 10.0%, 2.7% and 2.7% among patients, haemodialysis workers and controls, respectively. Amidst patients, the most frequent HBV genotypes were A (30.6%), D (57.1%) and F (12.2%). Univariate analysis showed association between HBV infection and total time in haemodialysis, type of dialysis equipment, hygiene and sterilization of equipment, number of times reusing the dialysis lines and filters, number of patients per care-worker and current HCV infection. The logistic regression model showed that total time in haemodialysis, number of times of reusing the dialysis lines and filters, and number of patients per worker were significantly related to HBV infection. Conclusions Frequency of HBV infection among haemodialysis patients at Santa Catarina state is very high. The most frequent HBV genotypes were A, D and F. The risk for a patient to become HBV positive increase 1.47 times each month of haemodialysis; 1.96 times if the dialysis unit reuses the lines and filters ≥ 10 times compared with haemodialysis units which reuse < 10 times; 3.42 times if the number of patients per worker is more than five. Sequence similarity among the HBV S gene from isolates of different patients pointed out to nosocomial transmission.
