    Full Text Available The aim of this study was to determine the prevalence and the incidence of hepatitis B virus (HBV among haemodialysis (HD subjects and to evaluate whether testing for serological markers at the time of admission is suitable for HBV screening in this population. One hundred twenty-three patients belonging to two HD centres from São Paulo, Brazil, were tested prospectively. HBV DNA was detected by polymerase chain reaction (PCR in each of the prospective subjects (n = 123 during one year. Additionally, all samples (n = 1,476 were analysed for HBV serological markers. The prevalence of hepatitis B core antibody (anti-HBc, hepatitis B surface antigen (HBsAg and HBV DNA were 34.1%, 15.4% and 8.1%, respectively, while the incidence was null. Fluctuation in HBV serology was observed in one patient. Only 37.8% (17/45 of cases responded to the HBV vaccine. Our results suggest that employing more than one HBV marker and repeated follow-up evaluations may improve HBV screening in HD units.

    The histological features of 40 spleens surgically removed from maintenance haemodialysis patients are reported. Twenty-four of the 40 (60%) showed massive iron loading and a significant direct correlation was found between iron loading and the amount of intravenous iron dextran administered. Since parenteral iron dextran appears to be a major factor in causing iron overload in haemodialysis patients its use as a method of iron replacement in these patients would appear inappropriate.

  8. [Psychometry of depression in patients undergoing haemodialysis (author's transl)].

    1981-01-01

    Over a period of 8 days, 32 haemodialysis out-patients were studied. Psychometric alien- and self-rating questionnaires were completed twice a day. The aim of the study was to produce a survey of the frequency and severity of depression in haemodialysis patients. It was speculated that the potency of haemodialysis in producing depression might be a helpful model in searching for biochemical factors in this disorder. Self-ratings showed short-term depressive changes in mood in about 15% of cases, which were not confirmed by alien-rating scales. It is concluded that neither incidence and severity nor longitudinal and cross-sectional profiles support a biochemical determination of depression in haemodialysis patients.

    Haemodialysis treatment requires reliable vascular access. Optimal access is provided via functional arteriovenous fistula (fistula), which compared with other forms of vascular access, provides superior long-term patency, requires few interventions, has low thrombosis and infection rates and cost. However, it has been estimated that between 20% and 60% of fistulas never mature sufficiently to enable haemodialysis treatment. Mapping blood vessels using imaging technologies before surgery may identify vessels that are most suitable for fistula creation. We compared the effect of conducting routine radiological imaging evaluation for vascular access creation preoperatively with standard care without routine preoperative vessel imaging on fistula creation and use. We searched Cochrane Kidney and Transplant's Specialised Register to 14 April 2015 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. We included randomised controlled trials (RCTs) that enrolled adult participants (aged ≥ 18 years) with chronic or end-stage kidney disease (ESKD) who needed fistulas (both before dialysis and after dialysis initiation) that compared fistula maturation rates relating to use of imaging technologies to map blood vessels before fistula surgery with standard care (no imaging). Two authors assessed study quality and extracted data. Dichotomous outcomes, including fistula creation, maturation and need for catheters at dialysis initiation, were expressed as risk ratios (RR) with 95% confidence intervals (CI). Continuous outcomes, such as numbers of interventions required to maintain patency, were expressed as mean differences (MD). We used the random-effects model to measure mean effects. Four studies enrolling 450 participants met our inclusion criteria. Overall risk of bias was judged to be low in one study, unclear in two, and high in one.There was no significant differences in the number of fistulas that were successfully created (4

  10. Nonocclusive ischaemic bowel disease in patients on chronic haemodialysis

    Six patients with chronic renal failure on longstanding haemodialysis are presented, in whom nonocclusive bowel ischaemia occurred as a rare complication of their underlying disorder. Factors implicated in the development of bowel ischaemia in these patients are chronic constipation resulting in increased intraluminal pressure on the bowel wall, premature and progressive arterial disease and bouts of hypotension accompanying the haemodialysis procedure. Contrast studies of the bowel and computed tomography examination can suggest the diagnosis, but angiography alone provides the exact answer in demonstrating nonocclusive mesenteric ischaemia. In patients with chronic renal failure and longstanding dialysis presenting with abdominal symptoms this diagnosis should be considered. (orig.).

    Full Text Available BACKGROUND Patients with end-stage renal failure commonly have different cardiovascular diseases. Although, a decline in cardiovascular death has recently been observed in the general population. A similar trend has not been seen in dialysis patients. In this study, we have compared the electrocardiographic changes in patients with end-stage renal disease before and after haemodialysis. We have assessed the effect of haemodialysis on QT and corrected QT intervals and their dispersions in patients with end-stage renal disease on regular haemodialysis and also the effect of electrolytes- serum potassium, sodium and calcium on QT and corrected QT interval and their dispersions, before and after haemodialysis in patients with end-stage renal disease. MATERIALS AND METHODS Hundred patients with end-stage renal disease on twice a week hospital haemodialysis were randomly taken up for this study. The clinical history, examination, ECG (both pre and post HD and serum electrolytes was done on each patient. ECG was coded and analysed blindly for QT interval, corrected QT and their dispersions by one observer. The obtained data was analysed statistically using the ANOVA test, Student’s paired t-test and both simple and multiple linear logistical progression. RESULTS This study shows that at the end of HD (post-HD, the data showed significant increases in QTmax and QTcmax interval prolongation and QT and QTc interval dispersion in patients with end-stage renal failure receiving haemodialysis. The results of this study may add a new dimension to recent reports indicating the usefulness of QT dispersion as a predictor of sudden death after myocardial infarction in heart failure of ischaemic aetiology, hypertrophic cardiomyopathy as well as the risk of arrhythmia in the long QT syndrome. On analysing the relation between the changes in electrolytes and the increase in the QT and corrected QT dispersions, the study found no correlation between the electrolyte

    Haemodialysis patients often have impaired vascular function that can contribute to mortality. Endothelial-dependent and -independent vascular function can be assessed using the brachial artery reactivity (BAR) technique that measures flow-mediated dilatation (FMD) and the response to glyceryl trinitrate (GTN), respectively. The aim of this pilot study was to determine whether BAR measurements in haemodialysis patients were associated with mortality. Brachial artery responses to FMD and administration of GTN were assessed in consecutive haemodialysis patients. Patients were then followed up to 18 months after BAR measurements. Seventeen patients were included in the study. After 18 months of follow-up, patients were divided into two groups: survived (n=12) and deceased (n=5). Patients who survived had a significantly greater median percentage vasodilatation to GTN than those who died (19.1% vs 8.8%; P=0.04); and a significantly greater median area under the diameter change-time curve (318 vs 146 mm/s; P=0.03). However, there were no significant differences between survivors and deceased in median percentage vasodilation to FMD (6.0% vs 4.3%; P=0.21), time to peak dilation (45 vs 40s; P=0.66) or area under the diameter change-time curve (35.5 vs 20 mm/s; P=0.29). In this pilot study in a small group of haemodialysis patients, endothelial-independent vasodilatory response to GTN was associated with mortality and was of better prognostic value than the endothelial-dependent response to FMD. This finding needs to be investigated in a larger cohort. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

  13. Evaluation of spiritual well-being in haemodialysis patients.

    Spirituality can be defined as a personal search for meaning and purpose in life that may or may not encompass religion. In this article we report on the development and testing of an instrument for measuring spiritual well-being within a sample of haemodialysis patients. The main instrument, a 21-item Meaning in Life Scale (MiLS), comprises four scales: Life Perspective, Purpose and Goals, Confusion and Lessened Meaning, Harmony and Peace, and Benefits of Spirituality. A total score for spiritual well-being is also produced. We also used the following variables: clinical (time on haemodialysis, modified Charlson comorbidity index), sociodemographic (age, gender), and self-assessments of health, quality of life (general and recent), personal happiness, religiosity, and belief in the afterlife. A cross-sectional study was carried out on 94 haemodialysis patients. This study demonstrates that the MiLS-Sp is a psychometrically sound measure of spiritual well-being for dialysis patients (reliability, validity) as they manage the complex demands of a chronic illness. Spiritual well-being was significantly associated with various quality of life variables, health status, personal happiness, or religiosity in patients on dialysis. There was no relationship between spirituality scores and comorbidity, HD duration, gender, or age. Spiritual well-being is relatively low in dialysis patients. Spirituality may play an important role on psychological well-being, quality of life, and self-rated health for patients on haemodialysis. Spiritual well-being in these patients is relatively low. Results suggest that assessing and addressing spiritual well-being in dialysis patients may be helpful in clinical practice.

    To determine the effect of aromatherapy on pruritus observed in haemodialysis patients. Although the prevalence of pruritus in kidney failure has decreased in the recent years, pruritus is a difficult and serious problem which concerns the majority of haemodialysis patents and is hard to cure. A prospective, pretest-post-test quasi-experimental design was used. The research is quasi-experimental clinical trial conducted as pretest and post-test with control groups between January 2011-April 2012, in haemodialysis units of hospitals in Erzurum. The collection of the data is achieved using a questionnaire to detect the patients' individual and pruritus score scale and to clarify certain laboratory parameters regarding the pruritus. Chi-square analysis and t-test are used for the analysis of data. The experimental group's mean post-test pruritus scores (7·20 ± 3·14) were found to be lower than that of control group patients (10·00 ± 2·47), and a highly significant difference was found between the groups (p aromatherapy was found to decrease the pruritus problem of haemodialyses patients and led to positive changes in some laboratory parameters related to pruritus. One of the roles of health professionals is to advise individuals, who are living on this problem, using the nonpharmacological methods in checking the itching. By preventing or reducing uraemic pruritus, aromatherapy may also improve quality of life in this patient group. © 2014 John Wiley & Sons Ltd.

    This article is a report of the development and testing of the hypothetical model that illustrates relationships between treatment adherence and its psychosocial influencing factors and to elucidate the direct and indirect (mediating) effects of factors on treatment adherence. Poor adherence has been consistently reported in haemodialysis patients. Much research has showed various influencing factors of adherence, but these studies have failed to identify consistent influencing factors. This study was performed using a non-experimental, cross-sectional design. The study subjects were 150 end-stage renal failure patients on haemodialysis at a university hospital located in Incheon, South Korea. Data were collected over 10 months (June 2010-April 2011). The hypothetical model provided a good fit with data. Haemodialysis-related knowledge, perceived barrier to adherence, self-efficacy on adherence, and healthcare provider support had significant effects on adherence. Self-efficacy was found to mediate barrier-adherence and family support-adherence relationships. Self-efficacy in combination with barrier, family support, and healthcare provider support was found to mediate the depression-adherence relationship. Strategies aimed at the development of successful adherence interventions should focus on reducing perceived barriers and enhancing self-efficacy and knowledge. It can be suggested that efforts to improve the healthcare provider-patient relationship would enhance adherence. In depressive patients, strategies that promote self-efficacy and the support of family or healthcare providers could diminish the negative impact of depression on adherence. © 2013 Blackwell Publishing Ltd.

    The main objective of the study is to assess the nutritional status in patients on chronic haemodialysis in Jamaica using the Subjective Global Assessment tool and to correlate this with measured serum nutritional biomarkers, and also to identify nutritional biomarkers that can be used to assess nutritional status of patients with end-stage renal disease (ESRD). Two hundred and nine consecutive patients on haemodialysis were selected from dialysis centres in Kingston, the capital of Jamaica, St. Catherine and Manchester Jamaica. The nutritional status of each participant was assessed using the Subjective Global Assessment tool in an interview performed by the researcher. Serum albumin, blood urea nitrogen and creatinine, highly sensitive complement reactive protein (hsCRP) and total fasting cholesterol were determined from a single serum sample. Only patients with ESRD were selected. Patients with acute renal failure or those with ESRD who were admitted in the previous two weeks were excluded from the study. Informed consent was obtained prior to interview and obtaining blood samples. Of the total participants, 54.5% (n=114) were male and 45.5% (n=95) female. The mean age for males was 51.9 years and females 47.6 years. Diabetes was documented as the most common cause of chronic renal disease and was found in 29.7%, hypertension in 24.4% and chronic glomerulonephritis in 22% of the participants. Approximately 80% of the study population had moderate malnutrition. There was a significant association between moderate malnutrition and a diagnosis of ESRD secondary to diabetes mellitus, p = 0.03. Being on haemodialysis for 10 mg/L was associated with moderate malnutrition, though statistical significance was not met (p = 0.39). Factors associated with malnutrition in patients on dialysis were having ESRD secondary to diabetes mellitus, dialysis duration for < or = six months, low serum albumin, pre-dialysis serum creatinine of 880 micromol/L, low total cholesterol and

    Haemodialysis patients suffer from chronic systemic inflammation and high incidence of cardiovascular disease. One cause for this may be the failure of diseased kidneys to eliminate immune mediators. Current haemodialysis treatment achieves insufficient elimination of proteins in the molecular weight range 15-45 kD. Thus, high cut-off dialysis might improve the inflammatory state. In this randomized crossover trial, 43 haemodialysis patients were treated for 3 weeks with high cut-off or high-flux dialysis. Inflammatory plasma mediators, monocyte subpopulation distribution and leucocyte gene expression were quantified. High cut-off dialysis supplemented by a low-flux filter did not influence the primary end-point, expression density of CD162 on monocytes. Nevertheless, treatment reduced multiple immune mediators in plasma. Such reduction proved - at least for some markers - to be a sustained effect over the interdialytic interval. Thus, for example, soluble TNF-receptor 1 concentration predialysis was reduced from median 13·3 (IQR 8·9-17·2) to 9·7 (IQR 7·5-13·2) ng/mL with high cut-off while remaining constant with high-flux treatment. The expression profile of multiple proinflammatory genes in leucocytes was significantly dampened. Treatment was well tolerated although albumin losses in high cut-off dialysis would be prohibitive against long-term use. The study shows for the first time that a dampening effect of high cut-off dialysis on systemic inflammation is achievable. Earlier studies had failed due to short study duration or insufficient dialysis efficacy. Removal of soluble mediators from the circulation influences cellular activation levels in leucocytes. Continued development of less albumin leaky membranes with similar cytokine elimination is justified. © 2015 Stichting European Society for Clinical Investigation Journal Foundation.

    Objective To translate and culturally adapt the tool Categorización de usuario según dependencia y riesgo en unidades de hemodiálisis (CUDYR-DIAL) into Brazilian Portuguese. Method This is a methodological study for the translation and cultural adaptation or localization of the instrument CUDYR-DIAL. Results In the pre-test stage, three nurses applied the instrument to 78 patients of the haemodialysis unit of the São Lucas Hospital of the Pontifícia Universidade Católica do Rio Grande do Sul. The average scores of each item were compared and no statistically significant differences were found in the data of the three evaluators, which demonstrates that the score of each professional in each item converges to the same value. Considering the estimation of reliability, Cronbach's alpha determined for the 14 items of the scale presented a minimum of 0.796 and a maximum of 0.799. Conclusion The instrument was translated, but the cultural adaptation was not necessary. It presents good reliability and will contribute to qualify the care of haemodialysis patients.

    To explore the experiences of safety of adult patients during their haemodialysis treatment. Haemodialysis is a complex treatment with a risk for harm that causes anxiety among many patients. To date, no in-depth study of haemodialysis patients' emotional responses to conditions of their treatment exists. A descriptive exploratory qualitative study using content analysis was conducted. Outpatients (≥18 years old) (n = 12) who were treated with haemodialysis for more than half a year were purposefully selected from two haemodialysis units (one in an academic hospital and one in a top clinical hospital) in the Netherlands. Data were collected through in-depth individual interviews from January-April 2013. Analysis of the transcribed interviews consisted of open coding, creating categories and synthesis. Patients defined 'safety' as feeling safe from physical or emotional threats. Four main categories were identified in the descriptions of haemodialysis patients' experiences of safety: (a) insecurity; (b) trust in the nurse; (c) presence of the nurse; and (d) patients' need to control their situation. Although haemodialysis patients perceived multiple risks, most patients reported feeling safe during their treatment. The nurse had a pivotal role in promoting patients' feelings of safety. Nurses should take into account patients' coping strategies because these coping strategies may cause some patients to feel anxious, especially when patients say that they leave everything to the nurse, yet they still desire control over their treatment. © 2015 John Wiley & Sons Ltd.

    Background To determine the prevalence of xerostomia and hyposalivation in Haemodialysis (HD) patients, to clarify risk factors, assess patient´s quality of life, and to establish a possible correlation among interdialytic weight gain (IDWG) and xerostomia. Material and Methods This study was performed on a group of 50 HD patients. Data were collected using a questionnaire containing demographic and clinical variables, a visual analogue scale (VAS) for xerostomia, IDWG, and an oral health impact profile questionnaire (OHIP-14). Unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) were collected. Results A total of 28 HD patients (56%) suffered xerostomia. Dry mouth was associated with hypertension (OR, 5.24; 95% CI, 1.11-24.89) and benzodiazepine consumption (OR, 5.96; 95% CI, 1.05-33.99). The mean xerostomia VAS and OHIP-14 scores were 31.74±14.88 and 24.38±11.98, respectively. No significant correlation was observed between IDWG% and VAS and OHIP total score. Nonetheless, a positive correlation between VAS level of thirst and IDWG% was found (r=0.48 p=0.0001). UWS and SWS means (determined in 30 patients) were 0.16±0.17 and 1.12±0.64, respectively. Decreased values of UWS and SWS were reported in 53.33% and 36.66% of HD patients. Conclusions Xerostomia in HD has a multifactorial aetiology due to accumulative risks as advanced age, systemic disorders, drugs, fluid intake restriction, and salivary parenchymal fibrosis and atrophy. Therefore, it is important to detect possible xerostomia risk factors to treat correctly dry mouth in HD patients and avoid systemic complications.

    The study aimed to describe end of life for patients treated with maintenance haemodialysis as narrated by their close relatives. Many patients undergoing haemodialysis are older, have several comorbidities and underestimated symptoms and are in their last year of life. To improve care, we need to know more about their end-of-life situation. Qualitative and descriptive. Qualitative retrospective interviews were conducted with 14 close relatives of deceased haemodialysis patients (3-13 months after death). Data were analysed using qualitative content analysis. The study is ethically approved. In the last months, a gradual deterioration in health with acute episodes necessitating hospital admissions was described. This involved diminishing living space and expressions of dejection, but also of joy. Three patterns emerged in the last weeks: uncertain anticipation of death as life fades away; awaiting death after haemodialysis withdrawal; and sudden but not unexpected death following intensive care. Findings show complexities of decisions on haemodialysis withdrawal. Different end-of-life patterns all involved increasingly complex care needs and existential issues. Findings show a need for earlier care planning. The identification of organisational factors to facilitate continuity and whole person care to meet these patients' specific care needs with their complex symptom burdens and comorbidities is needed. Findings indicate the need for integration of a palliative care approach in the treatment of patients in haemodialysis care. © 2015 Nordic College of Caring Science.

    This study aims to describe patients' perspectives on the transition to home haemodialysis. Up to three sequential semi-structured interviews were conducted with 20 patients during the transition to home haemodialysis at an Australian renal unit. Transcripts were analysed thematically. Participants completed a satisfaction questionnaire after commencing home haemodialysis. We identified six themes: persevering despite trepidations (diminishing intimidation of machinery, acquiescing to fatal risks, reconciling fears of cannulation, dispelling concerns of neglect and tolerating necessary concessions); optimizing the learning pathway (practising problem solving, learning from mistakes, grasping technical complexity, minimizing cognitive overload and progressing at own pace); developing confidence (believing in own abilities, adapting to independence, depending on caregiver partnership and faith in crisis support); interrupted transition momentum (lacking individual attention, language barriers, installation delays, interfering illness and complications and acclimatizing to new conditions); noticing immediate gains (reclaiming lifestyle normality, satisfying self-sufficiency, personalizing treatment regime and thriving in a positive environment); and depleting resources and energy (exhaustion with gruelling routine, confronting medicalization of the home, draining financial reserves and imposing family burden). Fewer than 30% of respondents indicated low satisfaction with staff availability domains, staff interpersonal domains or technical domains. Home haemodialysis training fosters confidence in patients; however, many patients experience stress because of medical isolation, treatment responsibilities, family impositions and financial difficulties. Addressing patient's on-going psychosocial concerns may alleviate burdens on patients and their families during the transition to home haemodialysis. © 2016 Asian Pacific Society of Nephrology.

    The viral infections are frequent in haemodialysis patients, notably those due to the hepatitis C virus (HCV), the hepatitis B virus (HBV) and the human immunodeficiency virus (HIV). The objective of this study is to determine the prevalence of the hepatitis C, the hepatitis B, the HIV infection in haemodialysis patients and the main risk factors for hepatitis C in the chronic haemodialysis patients treated in haemodialysis unit of Ibn Rochd University Hospital in Casablanca. This retrospective study was performed in 186 chronic haemodialysis patients and showed a high prevalence of HVC infection (76%), the prevalence of HBV infection was at 2%, none of the patients had detectable antibodies of HIV. Among the patients infected by the HCV, the mean duration of dialysis was 8,7 years. The mean number of blood units transfused was 16,5. Seventeen patients (11%) had no history of blood transfusion. In conclusion, the blood transfusion is not considered to be a like a major risk factor of the HCV infection in haemodialysis patients and this since the systematic detection of the anti-HCV antibodies in the blood donors. The nosocomial transmission of HCV seems to be the main risk factor HCV infection in the haemodialysis units requiring a strict adherence to infection control procedures for prevention of HVC infection in haemodialysis patients.

    Full Text Available This study was intended to examine the effects of lavender essential oil aromatherapy on anxiety and depression in haemodialysis patients. This randomised clinical trial was conducted on 72 haemodialysis patients divided into control and experimental groups. The control group only received the routine care. The experimental group received aromatherapy with 3 drops of lavender essential oil 5% for 10 minutes every time they underwent haemodialysis for a period of one month. Anxiety and depression were measured in both groups at baseline and by the end of the second and fourth weeks during the first hour of a dialysis session. The rANOVA showed no significant difference between the two groups in terms of the severity of anxiety before the intervention and by the end of the second and fourth weeks (p  =  0.783. However, the  rANOVA revealed a significant difference with respect to the severity of depression between the two groups (p  =  0.005. Current research suggests that we need various concentrations of lavender essential oil to relieve anxiety compared to depression. In sum, future studies are required to investigate different concentrations of lavender essential oil at different times during haemodialysis sessions to obtain specific doses for lavender essential oil to be used on haemodialysis patients suffering from anxiety and depression.

    Premature loss of permanent teeth leads to stomatognathic system disability. It is a very serious but underrated problem for patients with chronic renal failure. The aim of study was analyse the degree of loss of masticatory function and number of teeth present for haemodialysis patients, and to define patients' needs for prosthetic treatment, which could restore correct occlusal condition. Sixty-nine haemodialysis patients treated at the Nephrology and Transplantology Clinic with the Dialysis Centre at the Medical University of Bialystok, Poland. We checked: 1) the total number of teeth and number of teeth separately for upper and lower jaws, 2) the existing prosthetic restorations and 3) the preserved masticatory function. More male than female patients were in possession of full dentition.All patients with at least 28 natural teeth with retained occlusal contacts whilst chewing were males (4; 10% males; 5.7% of the whole group). There were 15 edentulous patients: 7 males (10%) and 8 females (11.5%). Hundered percent of female patients presented with various degrees of tooth loss and needed prosthetic treatment. Nearly 70% of tested haemodialysis patients did not have a reconstructed masticatory function. The population of haemodialysis patients from the North East part of Poland are patients with severe stomatognathic system dysfunctions. It is of importance for dentists, as well as nephrologists, to understand the essence of the problem, as the general health of a patient cannot be improved without ensuring functional comfort of such as important system as the masticatory one.

    Full Text Available BACKGROUND To study the incidence of acute cardiovascular complications during haemodialysis in patients with chronic kidney disease with end-stage renal failure on maintenance haemodialysis. METHODS Patients with chronic kidney disease with end-stage renal failure on maintenance haemodialysis at King George Hospital, Andhra Medical College, Visakhapatnam, India, were studied during the period of June 2015 to August 2016. In our study, all the 100 patients underwent 8510 haemodialysis sessions during 1-year period of study. RESULTS Cardiovascular complications are the most common intradialytic complications occurred during the study. Hypotension is the commonest of all the intradialytic as well as cardiovascular complications with a frequency of 1278, which account for 15.01% of the haemodialysis sessions. This was followed by 879 episodes of hypertension (10.32%, 190 episodes of cardiac arrhythmias (2.23%, which include complex ventricular arrhythmias and supraventricular arrhythmias and 162 episodes of chest pain (1.90%. Of the 100 patients, 37% of patients developed cardiac arrhythmias during haemodialysis. The frequency of arrhythmic episodes was 190 (2.23%. Among these, Supraventricular Arrhythmias (SVA and Complex Ventricular Arrhythmic (CVA episodes account for 159 (83.68% and 31 (16.31%, respectively. CVA and SVA occurred in 29% and 19% of patients in the study group, respectively. Both CVA and SVA occurred in 12% of patients. CONCLUSION Intradialytic hypotension is the most common acute intradialytic complication in patients with chronic kidney disease with endstage renal failure undergoing maintenance haemodialysis. This is followed by intradialytic hypertension. Sudden cardiac arrest is the most common cause of death during haemodialysis in patients with end-stage renal disease on haemodialysis. Mortality is high in patients with end-stage renal failure in maintenance haemodialysis with ischaemic heart disease.

    Demodex folliculorum (DF) is resident in human pilosebaceous follicles. Mite density is low in healthy skin. Many cases of demodicosis in association with immunosuppression have been reported. Patients undergoing haemodialysis are also immunosuppressed. We aimed to compare the Demodex folliculorum density in haemodialysis patients and healthy subjects. Mite density of 87 patients undergoing haemodialysis was compared with that of age- and sex-matched controls. Two samples of standardized skin surface biopsies were taken from each subject from the forehead, cheek and nose. The number of mites counted on the surface area of 1 cm2 was accepted as the density of DF. The length and width of mites were measured by oculometer. DF density was found in 17 (19.54%) of the 87 dialysis patients and in 9 (10.34%) of 87 controls. A mean mite density of 5.11+/-5.65 was found in dialysis patients and of 2.55+/-1.6 in controls. Differences between the two groups in mite density were not statistically significant (P=0.13). There was also no significant difference in mite length between the two groups (P=0.06). There was, however, a significant difference in mite width (P=0.018). Despite the presence of sebaceous gland atrophy in haemodialysis patients, the higher density of DF in these patients than controls supports the supposition that this mite can increase immunosuppression.

    Turkey is the fifth country in Europe with regard to the number of patients receiving haemodialysis (HD). However, only a limited number of studies have comparatively investigated the factors that affect quality of life in haemodialysis and peritoneal dialysis (PD) patients in Turkey. The purpose of the study was to investigate the factors that affect quality of life in haemodialysis and peritoneal dialysis patients, as well as providing a comparison of quality of life between these groups. In this cross-sectional study, Quality of Life Scale and a data form was completed by 300 dialysis patients who received treatment at five hospital-based dialysis units in Istanbul, Turkey. The data were evaluated using arithmetic mean values, standard deviations, minimums, maximums, percentages, independent groups t-tests, Spearman correlation analyses and one-way variance analyses. The quality of life values in peritoneal dialysis patients were found to be higher than those of haemodialysis patients (P quality of life in chronic dialysis patients was affected by various factors. © 2013 Wiley Publishing Asia Pty Ltd.

    To explore the perspectives of patients undergoing haemodialysis in Singapore on an imposed dietary and fluid restriction regime. Adherence to prescribed dietary and fluid restriction constructs the fundamental basis of self-care with improved morbidity and mortality. However, most patients have struggled to adhere in this aspect. Existing studies have presented limited understanding on the facilitators and barriers of dietary and fluid adherence among haemodialysis patients. An exploratory qualitative study. A purposive sample of 14 patients undergoing haemodialysis was recruited from a renal unit of a tertiary hospital in Singapore. Data were collected through face-to-face individual interviews and subsequently analysed by thematic analysis. Four themes emerged: (1) Pessimism, (2) Existing struggles, (3) Perceived quality of support, and (4) Immensity of self-discipline. The imposed dietary and fluid restriction is a constant struggle and a cause of suffering among haemodialysis patients in Singapore. Nonetheless, they are generally submissive to their fluid restrictions for the sake of survival or to meet the expectations of their loved ones. The imposed dietary restrictions are generally neglected. The findings from this study can provide useful information in reviewing existing educational strategies, policies and nursing care. This is especially important because most patients exhibit high reliance on healthcare professionals. © 2017 John Wiley & Sons Ltd.

    Evidence has validated that the nutritional status of hospitalized patients on haemodialysis could be compromised because of admission-related and hospital-associated morbidities on the background of their kidney disease. However, nutritional status is not assessed and monitored routinely during the hospitalization period. The aim of the present study was to assess the nutritional status of hospitalized patients requiring haemodialysis with the subjective global assessment (SGA) tool during the hospitalization period. This is a prospective cohort study conducted in an acute tertiary general hospital. Patients aged 21-75 years old, admitted for various illnesses and requiring haemodialysis between November 2011 and May 2012 were enrolled into this study. A trained dietician assessed patients' nutritional status with the SGA tool, which included historical data on weight change, dietary intake, gastrointestinal symptoms, functional capacity, comorbidities and physical examination on subcutaneous fat loss, muscle wasting and presence of oedema and/or ascites. Patients were categorized under three groups: SGA-A (well-nourished), SGA-B (moderately malnourished) and SGA-C (severely malnourished). Eighty patients (mean ± SD age = 59 ± 10 years; 76% Chinese ethnicity) were assessed. Mean ± SD body mass index (BMI) was 25.1 ± 6.1 kg/m(2) . SGA categories were 48% SGA-A, 46% SGA-B, and 6% SGA-C. Mean energy and protein intake (P nutritional status. More than half of the hospitalized patients requiring haemodialysis were malnourished. It is important to incorporate SGA in the care of hospitalized haemodialysis patients for early detection of malnutrition and for medical nutrition therapy to optimise patients' nutritional status for better outcomes. © 2015 Asian Pacific Society of Nephrology.

    Coping skills enable caregivers to establish and maintain supportive relationships with the haemodialysis patients they care for. These skills are very important in terms of social support, promotion of mental health and social and family relations. The aim of this study is to investigate the coping skills of Iranian family caregivers as they take care of patients undergoing haemodialysis. Twenty participants were selected for the study through purposive sampling. The data gathering techniques used for the research were in-depth and unstructured interviews. The researchers used an inductive thematic analysis approach to analyse the data generated from the interviews. Four main themes emerged from the data: help-seeking skills, self-nurturing skills, time management skills and stress management skills. The focus of attention was on the stress management coping skills of the caregivers of haemodialysis patients together with their ability to cope with complex problems. Healthcare providers, by taking into account these skills and strategies of empowerment, can help other caregivers of haemodialysis patients cope with their heavy care conditions and better define their purposes in caretaking. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Conclusion: The prevalence of chronic HBV infection in haemodialysis in Spain is low and so are the rates of immunisation against the virus. The vaccination schedules used are very diverse and have been observed to correlate with the immune response. It would therefore be necessary to establish a protocol for the most effective vaccination schedule to increase immunisation in these patients.

    Haemodialysis patients suffer from accelerated vascular calcification. The vitamin K-dependent matrix Gla protein (MGP) is one of the most powerful inhibitors of vascular calcification. Haemodialysis patients have high levels of the inactive form of MGP (desphosphorylated-uncarboxylated-MGP, dp-uc-MGP) and may benefit from pharmacological doses of vitamin K2 (menaquinone) to improve the calcification inhibitory activity of MGP. To determine the optimal dose of menaquinone-7 (MK-7) for MGP activation, 200 chronic haemodialysis patients were recruited to randomly receive 360, 720 or 1080 µg of MK-7 thrice weekly for 8 weeks. Dp-uc-MGP was measured at baseline and after 8 weeks. Dietary intake of vitamin K1 (phylloquinone) and menaquinone was estimated based on a detailed questionnaire. At baseline, dp-uc-MGP was not associated with phylloquinone intake (P = 0.92), but correlated inversely with menaquinone intake (P = 0.023). MK-7 supplementation dose dependently reduced dp-uc-MGP. The levels decreased by 17, 33 and 46% in the respective groups. Drop-outs were mainly due to gastrointestinal side-effects related to the unpleasant smell of the tablets. Chronic haemodialysis patients have high levels of inactive MGP, possibly related to a low dietary vitamin K intake. Pharmacological doses of MK-7 dose-dependently reduce dp-uc-MGP. Menaquinone supplementation may be a novel approach to prevent vascular calcifications in chronic haemodialysis patients. © The Author 2013.

    Full Text Available Abstract Background Oxidative stress is associated with increased cardiovascular morbidity and mortality particularly in patients with end stage kidney disease. Although observational data from the general population has shown dietary antioxidant intake is associated with reduced cardiovascular morbidity and mortality, most clinical intervention trials have failed to support this relationship. This may be a consequence of not using an effective antioxidant dose and/or not investigating patients with elevated oxidative stress. The SPACE study, conducted in haemodialysis patients, reported that 800 IU/day of alpha tocopherol significantly reduced cardiovascular disease endpoints. A recent time course and dose response study conducted in hypercholesterolaemic patients that found 1600 IU/day of alpha tocopherol was an optimal dose. There is no such dose response data available for haemodialysis patients. Therefore the aim of this study is to investigate the effect of different doses of oral alpha tocopherol on oxidative stress in haemodialysis patients with elevated oxidative stress and the time taken to achieve this effect. Methods The study will consist of a time-course followed by a dose response study. In the time course study 20 haemodialysis patients with elevated oxidative stress will take either 1600 IU/day natural (RRR alpha tocopherol for 20 weeks or placebo. Blood will be collected every two weeks and analysed for a marker of oxidative stress (plasma F2-isoprostanes and alpha tocopherol. The optimum time period to significantly decrease plasma F2-isoprostanes will be determined from this study. In the dose response study 60 patients will be randomised to receive either placebo, 100, 200, 400, 800 or 1600 IU/day of natural (RRR alpha tocopherol for a time period determined from the time course study. Blood will be collected at baseline and every two weeks and analysed for plasma F2-isoprostanes and alpha tocopherol. It is hypothesised that

    Pain affects peoples' well-being and quality of life and is one of the most common symptoms experienced by people receiving haemodialysis (HD). To explore how Thai people receiving HD perceive pain, the effect of pain on their lives, and how they cope with and manage pain. Purposive sampling was used to recruit participants from two Thai outpatient haemodialysis facilities in Songkhla province. Face-to-face, in-depth individual interviews using open-ended questions were conducted during January and February 2012. The interviews were audio-recorded and transcribed verbatim. Data were analysed using Ritchie and Spencer's Framework method. Twenty people receiving HD participated in the study: age range 23-77 years; 10 were females. Three main types of pain emerged: physical pain, which occurred when needles were inserted during HD treatment and vascular access operations; psychological pain due to unfulfilled hopes and dreams and changes in family roles; and social pain. Perception of pain was influenced by the general populations' perceptions of chronic kidney disease. Participants used two main coping styles to manage pain: health-adjustment and health-behaviour styles. These two coping styles encompassed four specific coping strategies: religion, spirituality, accepting pain associated with HD treatment, and social support. Coping styles and strategies were influenced by Thai culture. The study elicited information that could help nursing staff understand how Thai people manage pain and the importance of cultural beliefs to their pain experience and coping strategies, which in turn can help nurses plan appropriate pain management. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Blood lead was measured and found to be high in one haemodialysis patient with atypical abdominal pain and peripheral neuropathy. This prompted an audit of blood lead concentrations in prevalent haemodialysis patients under the care of a University Teaching hospital. Blood lead was determined in 271 prevalent adult haemodialysis patients regularly dialysing three times a week, in five dialysis centres and/or on the home dialysis programme. All samples were carefully collected into lead-free plastic containers, and measured by graphite furnace atomic absorption spectrometry. 25.5% of haemodialysis patients had abnormal blood lead concentrations (>200 microg/L), compared with 59% with high-normal values of 100-200 microg/L, and only 15.5% with normal values (filter and reverse osmosis water purification device unit (r = 0.29, P water, blood lead was increased in 84.5% of prevalent haemodialysis patients. Single reverse osmosis machines and carbon filters may not be as effective at filtering out possible lead contamination compared with large industrial reverse osmosis devices and carbon filters, and thus blood lead testing should be considered for home haemodialysis patients, particularly in those areas where monochloramines are used to sterilize domestic water supplies.

    BACKGROUND: Secondary hyperparathyroidism is a common feature in patients with chronic kidney disease. Its serious clinical consequences include renal osteodystrophy, calcific uremic arteriolopathy, and vascular calcifications that increase morbidity and mortality.Reduced synthesis of active...... vitamin D contributes to secondary hyperparathyroidism. Therefore, this condition is managed with activated vitamin D. However, hypercalcemia and hyperphosphatemia limit the use of activated vitamin D.In Denmark alfacalcidol is the primary choice of vitamin D analog.A new vitamin D analog, paricalcitol...... hyperparathyroidism and the tendency towards hyperphosphatemia and hypercalcemia. METHODS/DESIGN: This is an investigator-initiated cross-over study.

    Poor physical performance and protein-energy wasting (PEW) are health issues of major concern in haemodialysis patients. The conventional haemodialysis (CHD) regime, three times per week 3-5 h, is subject of discussion because of high morbidity and mortality rates. When patients switch from CHD to longer dialysis sessions, i.e. nocturnal haemodialysis (NHD), improvement in protein intake and increase in body weight is seen. However, it is unclear whether physical performance and more important aspects of PEW, such as body composition, improve as well. Therefore, the aim of this study is to investigate whether physical performance improves and PEW decreases, when patients switch from CHD to NHD. A second aim is to assess the influence of NHD on the biomarkers fibroblast growth factor-23 and sclerostin which are thought to be associated with malnutrition and mortality in patients on haemodialysis. This study is a prospective multicentre cohort study with an inclusion aim of 50 patients: 25 patients in a control group (three times per week, 3-5 h CHD) and 25 patients in a nocturnal group (three times per week, 7-9 h NHD). Primary outcome is change in physical performance, measured by the Short Physical Performance Battery. Additional measurements are a 6-min walk test, handgrip strength, a physical activity questionnaire and physical activity monitoring. The secondary outcome of the study is PEW, which will be evaluated by body weight, dual-energy X-ray absorptiometry, bio-electrical impedance spectroscopy, mid-upper arm muscle circumference, subjective global assessment, visual analogue scale for appetite and dietary records. Laboratory measurements including fibroblast growth factor-23 and sclerostin, and quality of life assessed with the Kidney Disease Quality of Life-Short Form are also studied. In every patient, four repeated measurements will be performed during one year of follow-up. This study will investigate whether physical performance improves and PEW

    Polypharmacy is commonly applied to elderly haemodialysis patients for treating terminal renal failure and multiple co-morbidities. Potentially inappropriate medications (PIMs) in multidrug regimens in geriatric populations can be identified using specially designed screening tools. The aims of this study were to estimate the prevalence of PIMs by applying the Screening Tool of Older Persons' Prescriptions (STOPP) criteria and the Beers criteria to elderly haemodialysis patients and to assess the association of some risk factors with the presence of PIMs. Fifty-one elderly haemodialysis patients participated; their median age was 74 (range 65-89) years, and 77 % of them were male. Demographic data, co-morbidity and medication lists were collected from the electronic medical records of the patients. The STOPP criteria were applied by two physicians independently to identify PIMs. The association of some risk factors with PIMs were assessed using Fisher's exact test. The patients used a median of 13 (range 7-21) medications per day. The overall prevalence of PIMs using the STOPP criteria was 63 %, and using the Beers criteria was 43 %. The most prevalent PIMs were proton-pump inhibitors. Benzodiazepines and first-generation antihistamines were related to side effects such as falls in the previous 3 months, and calcium-channel blockers were associated with chronic constipation. The number of PIMs was not significantly associated with number of medications, age, sex and co-morbidity. The STOPP criteria revealed a high prevalence of PIMs in a population of elderly patients receiving haemodialysis.

This comparative observational study was conducted at the Jinnah Postgraduate Medical Centre, Karachi, from February to July, 2008, and comprised stage-V chronic kidney disease patients. The patients were divided in two groups. Those who were on conservative management were placed in Group A, and those who were on maintenance haemodialysis were in Group B. Serum total lipid, cholesterol, triglycerides and high-density lipoprotein for both groups were assayed on chemical analyser and low-density lipoprotein was calculated by Friedwald equation. SPSS 17 was used for data analysis. Of the 120 patients, there were 60(50%) in each group. The mean age of patients in Group A was 46.33±14.56 years and in Group B was 43.4±14.1years. Of all, 64(53.3%) were men and 56(46.7%) were women. Mean systolic and diastolic blood pressure was 134±19.58mmHg and 83.6±14.14mmHg in Group A and 129±19.7mmHg and 79.7±12.1mmHg in Group B. Mean serum total lipid was significantly higher (pmaintenance haemodialysis was more hostile than those on conservative management, and posed increased risk of coronary heart disease.

    It is not known whether nutritional status differs between Australian Aboriginal and non Aboriginal haemodialysis subjects. The aim of this study was to investigate the nutritional status of Australian Aboriginal and non-Aboriginal haemodialysis subjects at satellite dialysis centres. Seventy-six (25 Aboriginal, 51 non-Aboriginal) prevalent haemodialysis patients were enrolled in a 3-month cross-sectional study. Each month anthropometric and biochemical measurements were collected. Nutritional status (diet history, patient-generated subjective global assessment (PG-SGA), handgrip strength) was assessed by a dietitian. PG-SGA detected mild to moderate malnutrition in 35% of Aboriginal patients and 25% of non-Aboriginal patients. The overall physical rating on the PG-SGA was significantly higher in Aboriginal patients, indicating the presence of a greater deficit in muscle mass in this population. Inter-dialytic weight gain was significantly greater in Aboriginal subjects (median [range] 3.0 [2.1-5.7] vs 2.5 [-0.3-5.0] kg, P1.6 and median normalized protein catabolic rate 1.5). Difficulties were encountered in obtaining dietary information from Aboriginal subjects using the diet history method. Subjects had acceptable parameters of dialysis adequacy; however, 35% had evidence of malnutrition. Further research should focus on establishing a knowledge base for the nutritional management for Aboriginal dialysis subjects, and the development of a validated individual dietary assessment method for use in this population group. © 2013 Asian Pacific Society of Nephrology.

    To systematically review the common composition and the analytical methods performed to derive symptom clusters in patients receiving haemodialysis, and to examine their common predictive and outcome variables. Patients receiving haemodialysis may suffer from multiple and interactive symptoms simultaneously, which may impact their mortality, morbidity and quality of life. The composition of these symptom clusters varies depending on the different assessment tools, the variant evaluation timing points and the various statistical methodologies. A detailed review of existing studies is needed. A systematic review of observational studies. Medline from 1950, CINAHL from 1960, Embase from 1980 and PsycINFO from 1967 as well as additional sources were searched. Content analysis was conducted to identify articles assessing the interrelationships of multiple symptoms. Five studies were identified. Several symptom clusters were identified with five common groupings being uraemic cluster, neuromuscular cluster, skin cluster, gastrointestinal cluster and energy/fatigue cluster. Four studies performed the principal component analysis with varimax rotation to extract symptom clusters and one study used correlation analysis. Different symptom assessment tools were used and each involving different array of symptoms. The predictive and outcome variables of symptom clusters also varied considerably. No studies have examined the longitudinal course and patients' subjective experiences of symptom clusters. Inconsistencies in the composition of symptom clusters across studies were identified due to inconsistencies in symptom assessment tools and statistical methodologies. Future studies should focus on an agreement about a robust and clinically relevant definition on symptom clusters; a multidimensional, valid and reliable symptom assessment tool; and an optimal analytical method in patients receiving haemodialysis. Knowledge of symptom clusters may contribute to understanding the

    1 A pharmacokinetic study on flucloxacillin and cloxacillin was performed to investigate the factors contributing to the higher serum concentrations reported for the former after oral administration. 2 The results obtained in a study performed in a group of volunteers with flucloxacillin administered orally and by continuous infusion, were compared with the results of a similar investigation with cloxacillin. Patients on chronic intermittent haemodialysis received flucloxacillin orally and as a single i.v. injection. The results of this part of the study were compared with those of an earlier study on cloxacillin in haemodialysis patients. Serum and urine concentrations of flucloxacillin and cloxacillin were determined by bio-assay, and a one-compartment model was used for the calculations. 3 Higher serum concentrations reached after oral administration of flucloxacillin as compared with cloxacillin were based not only on better oral absorption (53.7% and 32.9%, respectively) but also on slower (renal and extra-renal) elimination (T1/2 : 46 and 32 min, respectively). A significant difference between the apparent volumes of distribution of flucloxacillin and cloxacillin, which could contribute to higher serum concentrations, could not be demonstrated. Considerable individual variation occurs in the rate and amount of oral absorption, especially in patients. The elimination rate of flucloxacillin in haemodialysis patients (T1/2 : 2h 53 min) corresponds with the extra-renal elimination rate in healthy subjects. No influence of haemodialysis on the elimination rate constant of flucloxacillin was found; total plasma clearance was, however, slightly but significantly higher during dialysis. PMID:1234495

    The aims of this study were to assess haemodialysis nurses' work environment and investigate the correlation between work environment and patients' outcomes. A cross-sectional study was conducted at the 11 public hospital-based haemodialysis units of the 5th Regional Health Authority of Greece. The Practice Environment Scale of the Nursing Work Index (PES-NWI) was used to assess work environment. Nurses were asked to report the frequency of a series adverse events and errors. Study population consisted of 133 nurses (response rate 89.3%). The overall PES-NWI scored just work environment. Multivariate logistic regression analysis identified that hypotension (odds ratio (OR) = 0.3, 95% confidence interval (CI) = 0.1-0.9, P = 0.03), venous needle disconnection (OR = 0.14, 95% CI = 0.03-0.65, P = 0.012) and patient fall (OR = 0.02, 95% CI = 0.001-0.51, P = 0.018) were associated with a non-favourable work environment. Findings have important implications for improvement of haemodialysis work environment and enhancement of patients' safety. © 2013 Wiley Publishing Asia Pty Ltd.

    Chronic kidney disease is an emerging problem in the majority Muslim countries. Despite the uncertainties of the risks involved, some Muslim patients undergoing chronic haemodialysis choose to observe intermittent fasting during the month of Ramadan. This study aims to investigate the effect of Ramadan fasting in haemodialysis patients residing in a tropical climate country. This prospective cross sectional study recruited Muslim patients on regular haemodialysis from three haemodialysis centres in Kuala Lumpur from 15th July 2011 to 29th August 2011. Patients who fasted for any number of days were included (n = 35, 54% female, age 54±11 years). 89% of patients fasted for more than 15 days and 49% were diabetics. Dialysis parameters and blood samples were obtained one week prior to Ramadan and during the last week of Ramadan. The differences in dialysis parameters and biochemical values pre- and end-Ramadan were examined using paired t-test. Both pre- and post-dialysis weight were significantly decreased during Ramadan fasting compared to the month prior (p = fasting. There was a significant increase in serum albumin level (p = 0.006) and decrease in serum phosphate level (p = 0.02) at the end of Ramadan. Ramadan fasting is associated with reduced weight, improved serum albumin and phosphate level in our population of haemodialysis patients. A larger multi-centre study will allow us to understand more about the effects of fasting in this population.

    Haemodialysis (HD) is a life-saving but burdensome therapy for patients with end-stage renal disease (ESRD) which can have a detrimental impact on patients' quality of life and outcomes. There is currently little data on the health related quality of life (HRQOL) of Chinese ESRD patients undergoing HD and this study sought to examine the patterns of HRQOL and its associated factors within this population, as well as in comparison with the general local population. A cross-sectional study of 244 ESRD patients receiving HD in the hospital and in the community in Hong Kong was conducted using the Short Form-12 Health Survey version 2 (SF-12v2). All study subjects were one-to-one matched with subjects in a Hong Kong general population database by sex and exact age. Independent t-tests were performed to compare the mean SF-12v2 scores between HD patients and the general population, followed by one-way analysis of variance with post hoc Tukey's HSD tests to compare community-based haemodialysis, hospital-based haemodialysis and the general population. Multiple linear regressions were used to identify the factors (socio-demographic, clinical characteristics and comorbidities) associated with the HRQOL scores of ESRD patients receiving HD. The SF-12v2 Physical Functioning, Role Physical, Bodily Pain, General Health and Physical Component Summary scores of HD patients were significantly lower than the age-sex adjusted general population. However, the SF-12v2 Mental Health and Mental Component Summary scores of HD patients were significantly higher than the corresponding general population. Poorer HRQOL was associated with being female, smoking, unemployment and hospital-based haemodialysis. HD patients had substantially poorer physical HRQOL but better mental HRQOL than the age-sex adjusted general population. Patients receiving HD in the community setting had better HRQOL. Reasons for these observations will need to be further investigated. Those patients who are female

    Few studies have focused on the effect of music in patients undergoing haemodialysis. To determine the effects of live saxophone music on various physiological parameters and pain, mood and itching levels. A randomised controlled study with 114 patients undergoing haemodialysis with a control group (n = 57) and an experimental group (n = 57) who received 30 minutes of live saxophone music therapy. Systolic and diastolic blood pressure, pulse rate, glycaemia, oxygen saturation, pain, mood and itching levels were measured before and after the live music performance, resulting in baseline and post-test values for the patients in the experimental group. The experimental group showed a statistically significant reduction in pain level, and an improvement in mood and itching levels and in the oxygen saturation. Live saxophone music could be introduced to improve clinical and quality-of-life measures in patients undergoing haemodialysis. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Elderly patients on haemodialysis have a high prevalence of polypharmacy and are at risk of drug-related complications. More than 80 % of all prescribed drugs are metabolized by the cytochrome P450 (CYP) enzyme system. The aims of this study were to describe the prevalence of polymorphism in three CYP isoenzymes and the relationship between CYP polymorphism and prescribed drugs. Fifty-one elderly haemodialysis patients aged ≥65 years were included. CYP-genotyping was carried out in whole blood by a real-time PCR method for detecting common variant alleles in CYP2C9, CYP2C19 and CYP2D6. The allele frequencies were calculated using the Hardy-Weinberg equation. The overall prevalence of CYP polymorphisms (heterozygous and homozygous) was 77 %. The prevalence of heterozygous carriers of variant alleles coding for defective CYP2D6, CYP2C9 and CYP2C19 was 64, 22 and 55 %, respectively; the prevalence of homozygous carriers was 6 % for each of the CYP2D6, CYP2C9 and CYP2C19 enzymes. The prevalence of the CYP2D6*6, CYP2D6*9 and CYP2D6*41 variant alleles did not differ (p = 0.31) from that in a European Caucasian reference population. Twenty-three patients (45 %) had at least one CYP mutation and used drugs that are metabolized by the CYP isoenzymes. Metoprolol and proton-pump inhibitors were the most commonly used drugs that could be affected by a heterozygous or homozygous mutation. Polymorphisms of CYP2C9, CYP2C19 and CYP2D6 are common in elderly haemodialysis patients. Many of these patients have a phenotype with altered CYP enzyme activity and could benefit from close drug monitoring or a drug switch.

    PurposeThe study was designed to assess outcomes of arteriovenous (AV) accesses after interventional stent-graft deployment in haemodialysis patients.Materials and Methods63 haemodialysis patients with 66 AV fistulas and AV grafts were treated by interventional stent-graft deployment from 2006 to 2012 at our hospital. Data of these patients were retrospectively analysed for location of deployed stent-grafts, occurrence and location of (re-)stenosis and (re-)thrombosis. Complex stenosis was the most frequent indication for stent-graft deployment (45.5 %), followed by complications of angioplasty with vessel rupture or dissection (31.8 %).ResultsA high rate of procedural success was achieved (98.5 %). The most frequent location of the deployed stent-graft was the draining vein (66.7 %). Stent-graft deployment was more frequent in AV grafts than in AV fistulas. Primary patency was 45.5 % at 6 month, 31.3 % at 12 month and 19.2 % at 24 month. Primary patency was significantly better for AV fistulas than for AV grafts with deployed stent-grafts. Patency of the deployed stent-graft was much better than overall AV access primary patency with deployed stent-graft. Re-stenosis with thrombosis was the most frequent indication for re-intervention. Most frequent location of re-stenosis was the draining vein (37.1 %), followed by stenosis at the AV access (29.5 %) and the deployed stent-graft (23.5 %).ConclusionRe-stenosis and re-thrombosis remain frequent in AV fistulas and AV grafts in haemodialysis patients despite stent-graft deployment. Re-stenosis of the deployed stent-graft is, only in the minority of the cases, responsible for AV access dysfunction.

    Patients requiring haemodialysis have diverse clinical needs impacting on the longevity of their vascular access and their quality of life. A clinical practice scenario is presented that raises the potential of unsafe cannulation of a patient's vascular access as a result of minimal patient empowerment. Vascular access care is the responsibility of everyone, including the patient and carer. The aim of this narrative literature review (1997-2014) is to explore the current understanding of what factors influence the care of vascular access for haemodialysis. A narrative literature review allows the synthesis of the known literature pertinent to the research question into a succinct model or unique order to enable new understandings to emerge. The bio-ecological model was used to guide the thematic analysis of the literature. The narrative literature review revealed five themes related to care of vascular access: patient experience; relationships-empowerment and shared decision making; environment of healthcare; time; and quality of life as the outcome of care. The management of vascular access is complicated. Current available literature predominantly concentrates on bio-medical aspects of vascular access care. Contextualised vascular access care in the complex ecology of the patient and carer's lives has the potential to enhance nursing practice and patient outcomes. © 2015 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Haemodialysis is the most common form of medical management of patients affected by end-stage renal disease (ESRD). For haemodialysis to be successful, strict fluid and weight control is recommended. Education, in terms of self-care activities, is an important intervention for improving patients' outcomes. A self-efficacy promotion training programme can be an effective strategy to bring about behavioural change. The aim of this study was to investigate the effect of a self-efficacy promotion training programme on the body weight changes in patients undergoing haemodialysis. In this single-blind quasi-experimental study, we recruited a convenience sample of 63 patients undergoing haemodialy-sis from two teaching hospitals and allocated them randomly to the experimental or control group. Patients in the experimental group received a six-session self-efficacy promotion training programme while the control group received the routine care of the institute. Mean body weight gain and self-efficacy were measured before, immediately and two months after the study. The groups did not differ significantly regarding the study variable before the study. However, immediately and two months after the study, the mean body weight gain and self-efficacy in the experimental group were significantly lower and higher, respectively, than the control group (p < 0.05). Implementing a self-efficacy promotion training programme is effective in decreasing weight gain and increasing self-efficacy in patients undergoing haemodialysis. Nurses in haemodialysis units can use self-efficacy promotion training programmes as an effective intervention for improving patients' outcomes. © 2012 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    The main cause of malnutrition in haemodialysis patients is a spontaneous decline in energy and protein intakes. This study aims to report the dietary energy intake (DEI), dietary protein intake (DPI), and dietary micronutrient intake in a French HD population, to report factors associated with a low DPI and DEI, and to analyze if nutritional intake was correlated with nutritional status. We conducted an observational cross-sectional study in a haemodialysis population of 87 adult patients in July 2014. Daily nutritional oral intake, handgrip strength, body composition measured by bioimpedancemetry, and biological and dialysis parameters were obtained from medical records. Statistical analyses of parameters associated with DEI and DPI were performed. The median age (interquartile range) of the population was 77.3 [71.1; 84.8] years, 57.5% were men, and 52.9% had diabetes mellitus. Median weight-adjusted DEI was 18.4 [15.7;22.3] kcal/kg per day (1308 [1078; 1569] kcal/day), and median weight-adjusted DPI was 0.80 [0.66; 0.96] g/kg per day (57.5 [47.1; 66.8] g/day). In multivariate analysis, weight-adjusted DEI was statistically lower in patients with diabetes (coefficient [95%CI] -3.81[-5.21;-2.41] kcal/kg per day; P = 0.01) but was not associated with the others parameters. When DEI was not adjusted for weight, diabetes was no longer associated with DEI, but female gender (-178[-259;-961] kcal/day; P = 0.03) and a higher Charlson comorbidity index (-30[-44;-15]; P = 0.04) were associated with a lower calorie intake. Results for DPI were similar except that the Charlson comorbidity index did not reach significance. Diabetes is an important factor associated with low dietary intake in haemodialysis patients. Restrictive regimens should be prescribed cautiously in haemodialysis patients, especially in those with diabetes. © 2016 Asian Pacific Society of Nephrology.

    The objective of the study was to examine the quality of life amongst the end stage renal disease (ESRD) haemodialysis patients in Malaysia. A cross sectional descriptive study was conducted on 72 ESRD patients at a Dialysis Centre in Malaysia. The modified KDQOL-SF™ subscales, kidney disease-targeted scale and 36 item health survey scale questionnaires were used. The overall health rating was 66.73 ± 11.670 indicating good quality of life. There was no significant difference between quality of life for the different domains according to gender (p >0.05). However, there were significant differences between quality of life in the domain of burden of kidney disease. Physical functioning deteriorated significantly with age (p=0.012) while social functioning was lowest in the 50-65 years age group (p=0.037). Those who had no morbidities had significantly better scores on the effects of kidney (p=0.036), burden of kidney disease (p=0.011) and physical functioning (p=0.025). Patients undergoing haemodialysis have been found to have good quality of life despite having ESRD. It is therefore of paramount importance to constantly monitor the standard of care for these patients to enable them to live their life to the fullest.

    Hepatitis C virus (HCV) is an important health care problem in haemodialysis. Hepatitis C virus is both a cause and complication of kidney diseases. Yet there are limited information on antibody against HCV in patients on haemodialysis. The purpose of this study was to determine the prevalence of anti-HCV and the risk factors associated with HCV infection in a cohort of 100 participants on haemodialysis. They were consecutively recruited into the study, anti-HCV testing was made by the 3rd-generation ELISA System (C-100, C-33c, C-22). The prevalence of HCV antibody was 15%, risk factors associated with HCV antibody were history of blood transfusion and duration of session of haemodialysis; the risk increased with increased with the number of blood transfusion and seasons of haemodialysis. The observed high prevalence of HCV antibody among patients on haemodialysis reflect the quality of healthcare services and the standards of infection control practices in our haemodialysis units. Routine screening for HCV should be done before blood transfusion using third generation ELISA assays with high sensitivity and specificity. Safety measures should be taken in our haemodialysis units to prevent cross infection among patients and staffs. These safety measures include; discarding syringes, needles, gloves, bloodlines and dialysers after single use, and the use of sterile dressings on each patient visit.

    End stage renal failure (ESRF) has become a major health problem in Sub Saharan Africa (SSA). There were limited data about causes of ESRF in the Sudan. This is a cross sectional hospital based descriptive study. The subjects of the study are ESRF adults' patients on regular haemodialysis treatment in 15 haemdoialysis centres in Khartoum State-Sudan. Clinical and epidemiological data were obtained from 1583 patients. The medical files of each patient were reviewed to identify the cause of ESRF. Concerning the causes of ESRF, diabetes was diagnosed based on the past medical history and result of the glucose tolerance test, hypertension was diagnosed based on past history of hypertension based on blood pressure of more than 140/90 mmHg, glomerulonephritis was diagnosed based on results of previous kidney biopsies and on clinical grounds, polycystic kidney disease and obstructive uropathy were diagnosed based on abdominal ultrasound and other imaging modalities, sickle cell anaemia was diagnosed based on the result of haemoglobin electrophoresis, systemic lupus erythematosus was diagnosed based on the clinical criteria in addition to lab results of auto antibodies, and analgesic nephropathy was diagnosed based on past medical history of chronic analgesic drugs usage with no other identifiable risk factors. We included all ESRF patients on regular haemodialysis treatment. We excluded ESRF patients less than 18 years old. The results showed that the mean age of ESRF Patients was 49 ± 15.8 (years) and 63.4% were male and 76.3% were unemployed. The mean duration of haemodialysis is 4.38 ± 4.24 (years). The most common cause of ESRF in our patients was hypertension (34.6%) followed by chronic glomerulonephritis (17.6%), diabetes mellitus (12.8%), obstructive uropathy (9.6 %), autosomal dominant poly cystic kidney disease (ADPKD) (4.7%), chronic pyelonephritis (4.6%), analgesic nephropathy (3.5%). However in (10.7%) no cause was found. In patient aged less than 40 years

    This study aimed to investigate the effects of preferred music listening on anxiety and pain perception in patients undergoing haemodialysis. A two group experimental design was used. Sixty people diagnosed with end stage renal failure undergoing haemodialysis treatment participated in this study. Preferred music listening was applied as an intervention. Anxiety and pain were measured pre-test and post-test. The control group scored significantly higher in state anxiety than the experimental group and experienced significantly higher pain intensity in post-test phase. Findings provide experimental evidence to support the effectiveness of preferred music listening in medical settings.

    Full Text Available We prospectively followed-up new patients of tuberculosis while on maintenance hemodialysis at a State Government-run tertiary care institute. Between 2000 and 2010, 1237 new patients were initiated on maintainence hemodialysis. The number of patients diagnosed with tuberculosis after initiation of hemodialysis was 131 (10.5% of 1237. The age was 46.4 ± 10.4 (range 8-85 years and there were 90 (68.7% males. The number of patients diagnosed with tuberculosis on the basis of organ involvement were: Pulmonary-60, pleural effusion-31, lymph node-21, meningitis-8, pericardial effusion-7, peritoneum-2, latent tuberculosis-2. The incidence of tuberculosis in hemodialysis was found to be 105.9 per 1000 patient years. Male gender, diabetes mellitus, past history of tuberculosis, mining as an occupation, low serum albumin, and duration of hemodialysis more than 24 months, and unemployment were found to be significant risk-factors on univariate analysis.

    CVD remains the major cause of death for dialysis patients. Dialysis patients have both traditional and nontraditional risk factors, including the retention of advanced glycation end products (AGE). Tissue AGE can be measured by skin autofluorescence (SAF) and are a reliable measurement of chronic exposure. Dietary intake of AGE may be lower in vegetarian patients than in non-vegetarian patients, so we determined whether vegetarian patients had lower SAF than non-vegetarian patients. We measured SAF in 332 adult haemodialysis patients using a UV technique in a standardised manner. Information about patients' demographic data, laboratory results and current medicinal prescriptions was collected retrospectively from the hospital's computerised database. The mean patient age was 65·2 (SD 15·1) years, 64 % were men, 42 % were diabetic, and 66 % were Caucasian. The mean SAF was 3·26 (SD 0·95) arbitrary units (AU), and SAF was lower in vegetarians as compared to non-vegetarians (2·71 (SD 0·6) v. 3·31 (SD 0·97) AU, P= 0·002). SAF was negatively correlated on both univariate (r -0·17, P= 0·002) and multiple linear regression (β coefficient -0·39, 95 % CI -0·7, -0·07, P= 0·019). SAF, a marker of tissue AGE deposition, was reduced in vegetarian haemodialysis patients after correction for known confounders, which suggests that a vegetarian diet may reduce exposure to preformed dietary AGE. Dietary manipulation could potentially reduce tissue AGE and SAF as well as CVD risk, but further prospective studies are warranted to confirm the present findings.

    The title of this article refers not only to the patient who decides to let go of life, the quality of which on dialysis is such that death is preferable, but also to the family and the renal unit staff who have to let go of the patient who makes this decision. One such case is described in detail since the problem is not one restricted to the treatment of end-stage renal failure alone, but occurs more and more frequently in other branches of medicine and surgery.

    Metabolic alkalosis is a rare occurence in hemodialysis population compared to metabolic acidosis unless some precipitating factors such as nasogastric suction, vomiting and alkali ingestion or infusion are present. When metabolic alkalosis develops, it may cause serious clinical consequences among them are sleep apnea, resistent hypertension, dysrhythmia and seizures. Here, we present a 54-year-old female hemodialysis patient who developed a severe metabolic alkalosis due to baking soda ingestion to relieve dyspepsia. She had sleep apnea, volume overload and uncontrolled hypertension due to metabolic alkalosis. Metabolic alkalosis was corrected and the patient's clinical condition was relieved with negative-bicarbonate hemodialysis.

    Following intravenous administration, vancomycin is poorly metabolized and is mainly excreted unchanged in urine. Total body clearance is thus dependent on the kidney, and is correlated with glomerular filtration rate and creatinine clearance. Accumulation of vancomycin in patients with renal insufficiency may therefore occur, and this may lead to toxic side effects if dosage is not modified according to the degree of renal failure. Furthermore, vancomycin easily diffuses through dialysis mem...

    Sleep disorder in haemodialysis patients can lead to disturbance in their psychosocial function and interpersonal relations, and reduced quality of life. The aim of the present study was to investigate the effect of acupressure on the quality of sleep of haemodialysis patients. In a randomised controlled trial, 108 haemodialysis patients were randomly divided into three groups: true acupressure, placebo acupressure, and no treatment. The two acupressure groups received treatment three times a week for 4 weeks during dialysis. Routine care only was provided for the no treatment group. The main study outcome was sleep quality. The total Pittsburgh Sleep Quality Index score decreased significantly from 11.9±3.13 to 6.2±1.93 in the true acupressure group, from 11.3±3.69 to 10.6±3.82 in the sham acupressure group, and from 10.9±4.10 to 10.7±3.94 in the no treatment group.

    Along with basic survival and other clinical outcomes, patients' quality of life is an important indicator to reflect the needs of these patients. Human needs are classified in Maslow's hierarchy, where the most essential basic physiological need provides the base, and self actualisation is at the top of pyramid. The aim of this study is to identify the patients' needs who are on maintenance haemodialysis using concept of Maslow's hierarchy. The descriptive study was conducted in the dialysis unit of Suez Canal University Hospitals. The study included 50 patients attending the dialysis unit. The findings showed that the patients' highest need was for self-esteem (92.0%), whereas the lowest was for love and belonging (38.0%). Statistically significant relationships were revealed between the identified love and belonging needs and patients' age and the duration of dialysis (p = 0.008). The total needs score was lower with the longer duration of dialysis (59.6 ± 7.3), compared to those with a duration less than 24 months (65.7 ± 8.1), p = 0.02. Based on the main study findings it is concluded that haemodialysis patients' highest need was for self-esteem, and the lowest was for love and belonging. These needs increased with longer duration of dialysis. Nurses need to be aware of these findings in order to be able to supply the necessary support to help the patient regain his/her self-concept. © 2011 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    SUMMARY Background High dietary protein intake is associated with greater survival in maintenance haemodialysis (MHD) patients. High-protein foods may increase dietary phosphorus burden, which is associated with increased mortality in these patients. Hypothesis is: an egg white based diet with low phosphorus to protein ratio (phosphorus without deteriorating the nutritional status in MHD patients. Objective We assessed serum phosphorus and albumin levels in MHD patients who agreed to ingest one meal per day with pasteurised liquid egg whites without phosphorus additives, as principal protein source. Methods Thirteen otherwise stable MHD patients with serum phosphorus >4.0 mg/dl agreed to consume eight ounces (225 g) of pasteurised liquid egg whites one meal per day for six weeks. Recipes were suggested to improve diet variety. Results Thirteen participating patients included seven women, three African Americans and five diabetics. Twelve patients exhibited drop in serum phosphorus. Mean population fall in serum phosphorus was 0.94 mg/dl, i.e. from 5.58 ± 1.34 (mean ± SD) to 4.63 ± 1.18 (p = 0.003). Serum albumin showed an increase by 0.19 g/dl, i.e. from 4.02 ± 0.29 to 4.21 ± 0.36 g/dl (p = 0.014). Changes in phosphorus pill count were not statistically significant (p = 0.88). The egg white diet was well tolerated, and recipe variety appreciated. Conclusion Pasteurised liquid egg whites may be an effective diet component lowering serum phosphorus without risking malnutrition. Controlled trials are indicated to examine egg white based dietary interventions in MHD patients at home or during haemodialysis treatment. PMID:21288313

    Full Text Available BACKGROUND Psychiatric illness like depression is common in chronic kidney disease patients. With this rising incidence of chronic kidney disease in Kerala, we need to determine the extent of problem and find appropriate strategy to manage these cases. The purpose of this study was to find out the prevalence of depression in chronic kidney disease patients undergoing haemodialysis, the proportion of patients getting treatment for depression, various factors influencing the prevalence of depression in the dialysis group and also to find out a bedside tool for assessing the prevalence of depression which can be used by the treating physician as well. METHODS This is a cross-sectional observational prospective study conducted among 50 patients aged above 18 years undergoing haemodialysis. All underwent screening using Beck’s Depression Inventory Scale II and were simultaneously assessed for depression and confirmed by using diagnostic and statistical manual for mental disorders IV criteria, with the help of a psychiatrist. STATISTICS ANALYSIS Chi square test was applied to know the association between two categorical variables. Statistical significance was set at P<0.05. RESULTS Out of 50 patients, 23 were found to have depression using Beck’s Depression inventory scale II as well as diagnostic and statistical manual for mental disorders IV criteria. Out of the 23 patients diagnosed to have depression with Beck’s Depression inventory scale II, only 3 patients (13% were getting treatments for depression. Also depression was associated with hypoalbuminaemia, anaemia, hyponatraemia and hypocalcaemia. CONCLUSION Beck’s Depression Inventory scale was showing good correlation with diagnostic and statistical manual for mental disorders IV criteria diagnosis of depression and hence, it may also be used for screening depression, by the treating physician.

    Diabetes (DM) is common in haemodialysis (HD) patients and affects both blood pressure (BP) and arterial stiffness. Carotid femoral pulse wave velocity (PWV) reflects the stiffness of the aorta and is regarded as a strong risk factor for cardiovascular (CV) mortality in HD patients. However, PWV...... (HD) and 32 HD patients with DM (HD+DM). The SphygmoCor system was used for estimation of PWV. HD-duration, age, gender and BP medication were similar in the two groups. Mean DM-duration was 23±11 years and 25(78%) had type 2 DM. HD+DM had higher BMI (26±5 vs. 29±5 kg/m2, p=0.02), systolic BP (142......±20 vs. 152±21 mmHg, p=0.02) and pulse pressure (65±17 vs. 80±18 mmHg, p

    Full Text Available BACKGROUND: Chronic kidney disease is an emerging problem in the majority Muslim countries. Despite the uncertainties of the risks involved, some Muslim patients undergoing chronic haemodialysis choose to observe intermittent fasting during the month of Ramadan. This study aims to investigate the effect of Ramadan fasting in haemodialysis patients residing in a tropical climate country. METHODS: This prospective cross sectional study recruited Muslim patients on regular haemodialysis from three haemodialysis centres in Kuala Lumpur from 15th July 2011 to 29th August 2011. Patients who fasted for any number of days were included (n = 35, 54% female, age 54±11 years. 89% of patients fasted for more than 15 days and 49% were diabetics. Dialysis parameters and blood samples were obtained one week prior to Ramadan and during the last week of Ramadan. The differences in dialysis parameters and biochemical values pre- and end-Ramadan were examined using paired t-test. RESULTS: Both pre- and post-dialysis weight were significantly decreased during Ramadan fasting compared to the month prior (p = <0.001. There was a significant decrease in the amount of ultrafiltration (p = 0.002. There were no significant differences in dry weight, inter-dialytic weight gain, mean urea reduction ratio or blood pressure measurements comparing pre- and end of Ramadan fasting. There was a significant increase in serum albumin level (p = 0.006 and decrease in serum phosphate level (p = 0.02 at the end of Ramadan. CONCLUSION: Ramadan fasting is associated with reduced weight, improved serum albumin and phosphate level in our population of haemodialysis patients. A larger multi-centre study will allow us to understand more about the effects of fasting in this population.

    In clinical practice, dietary sodium assessment requires reliable and rapid screening tools. We wished to evaluate the usefulness of food frequency questionnaires (FFQ) in estimating dietary sodium intakes in haemodialysis patients. We used the Derby Salt Questionnaire (DSQ), and Scored Sodium Questionnaire (SSQ) to estimate sodium intake. Body composition was determined by bioimpedance. In total, 139 haemodialysis patients (95 men) completed the FFQs, with mean ± standard deviation age 67 ± 15 years. The mean FFQ scores were DSQ 3.5 ± 2.0 and SSQ 68.4 ± 24.5. Men had higher estimated dietary sodium intakes [DSQ median (range) 3.6 (0.6-10.1) versus female 2.2 (0.5-9.1), P = 0.007)]. Younger patients and those aged >75 years had the higher SSQ dietary sodium scores; 70.7 ± 27.8 and 76.8 ± 24.6 versus those aged 55-75 years, 61.8 ± 22.3, P = 0.04. Patients with greater estimated sodium intake had higher extracellular water (ECW) to intracellular water (ICW) ratios pre-dialysis [75.1 ±12.5 versus 67.7 ± 4.8, P sodium group (0.9 ± 13.7% versus 6.5 ± 14.1%, P = 0.04). Both questionnaires were acceptable to patients and identified higher estimated dietary sodium intake for men, those with greater ECW and, somewhat surprisingly, we found that older patients had a greater dietary sodium intake than expected.

    Vitamin K deficiency is known to be common in haemodialysis patients and associates with adverse outcomes in this population, particularly vascular calcification. We aimed to investigate the vitamin K status in a population of Chinese haemodialysis (HD) patients. We collected demographic and biochemical data from a population of maintenance HD (MHD) patients in our unit and a control group composed of healthy subjects from our outpatient clinic. Fasting serum samples from all subjects were collected for the measurement of known vitamin K-dependent proteins i.e. matrix Gla protein (MGP), osteocalcin (OC) and uncarboxylated osteocalcin (ucOC). We also quantified the fraction of ucOC to total OC (%ucOC). Differences of these parameters between groups were analyzed and risk factors of vitamin K deficiency based on the definition as per %ucOC were investigated. We enrolled 93 MHD patients as a test group and 93 healthy subjects as a control group. There was no significant difference in MGP between groups (4.0 ± 2.8 pg/mL in MHD vs 4.2 ± 1.2 pg/mL in control; P = 0.676). Mean %ucOC was significantly greater in the MHD patients as compared to control subjects (76.4 ± 20.0% in MHD vs 48.56 ± 15.5%; P vitamin K deficiency, with the former being an independent risk factor. Defining Vitamin K deficiency by %ucOC, suboptimal vitamin K levels appear common in Chinese MHD patients.

    Full Text Available Abstract Background Secondary hyperparathyroidism is a common feature in patients with chronic kidney disease. Its serious clinical consequences include renal osteodystrophy, calcific uremic arteriolopathy, and vascular calcifications that increase morbidity and mortality. Reduced synthesis of active vitamin D contributes to secondary hyperparathyroidism. Therefore, this condition is managed with activated vitamin D. However, hypercalcemia and hyperphosphatemia limit the use of activated vitamin D. In Denmark alfacalcidol is the primary choice of vitamin D analog. A new vitamin D analog, paricalcitol, may be less prone to induce hypercalcemia and hyperphosphatemia. However, a randomised controlled clinical study comparing alfacalcidol and paricalcitol has never been performed. The primary objective of this study is to compare alfacalcidol and paricalcitol. We evaluate the suppression of the secondary hyperparathyroidism and the tendency towards hyperphosphatemia and hypercalcemia. Methods/Design This is an investigator-initiated cross-over study. Nine Danish haemodialysis units will recruit 117 patients with end stage renal failure on maintenance haemodialysis therapy. Patients are randomised into two treatment arms. After a wash out period of 6 weeks they receive increasing doses of alfacalcidol or paricalcitol for a period of 16 weeks and after a further wash out period of 6 weeks they receive the contrary treatment (paricalcitol or alfacalcidol for 16 weeks. Discussion Hyperparathyroidism, hypercalcemia and hyperphosphatemia are associated with increased cardiovascular mortality in patients with chronic kidney disease. If there is any difference in the ability of these two vitamin D analogs to decrease the secondary hyperparathyroidism without causing hypercalcemia and hyperphosphatemia, there may also be a difference in the risk of cardiovascular mortality depending on which vitamin D analog that are used. This has potential major importance

    Full Text Available Introduction. Our knowledge in the field of cause of deaths in dialysis patients is rapidly expanding, yet we still do not fully understand how renalase regulates the processes of cardiovascular disease developing in end-stage renal disease. Increased sympathetic nerve activity observed in chronic kidney diseases due to raised catecholamines in plasma results from the absence of renalase. Renalase synthesized and secreted by the kidneys participate in the regulation of sympathetic tone and blood pressure. A family of natriuretic peptides has been identified – NT pro-BNP – which seems to be the best predictor of clinical outcome and marker of extracellular fluid overload, as well as predicting mortality, irrespective of renal function. Objective. The aim of the presented study was to investigate renalase concentration and investigate associations between NT-proBNP, as well as analyzed parameters in haemodialysis patients. Materials and method. The study was conducted among residents of the municipality and neighbouring villages in the province of Lublin, central-eastern Poland. 49 male subjects on haemodialysis, aged 65.3 ± 14.2 years, median time on haemodialysis: 37.5 months, were included. All study subjects underwent haemodialysis 3 times a week. The mean concentration of renalase in the entire study population was 126.59 ± 32.63 ng/mL. The circulating levels of NT-proBNP was 813.64 ± 706.96 pg/mL. A significant inverse correlation was found between NT-proBNP and renalase plasma levels (R = –0.3, P = 0.03. Conclusions. Inverse correlation between NT-proBNP and renalase plasma levels in haemodialysis patients were due to impaired kidney function, accompanied by increased sympathetic nerve activity, which have an impact on the development of hypertension and cardiovascular complications.

    Full Text Available Objective. To determine the association between serum total alkaline phosphatase (TAP and mortality in African maintenance haemodialysis patients (MHD. Patients and Methods. The study enrolled a total of 213 patients on MHD from two dialysis centers in Johannesburg between January 2009 and March 2016. Patients were categorized into a low TAP group (≤112 U/L versus a high TAP group (>112 U/L based on a median TAP of 112 U/L. Results. During the follow-up period of 7 years, there were 55 (25.8% deaths. After adjusting for cofounders such as age, other markers of bone disorder, and comorbidity (diabetes mellitus, patients in the high TAP group had significantly higher risk of death compared to patients in the low TAP group (hazard ratio, 2.50; 95% CI 1.24–5.01, P = 0.01. Similarly, serum calcium >2.75 mmol/L was associated with increased risk of death compared to patients within levels of 2.10–2.37 mmol/L (HR 6.34, 95% CI 1.40–28.76; P = 0.02. The HR for death in white patients compared to black patients was 6.88; 95% CI 1.82–25.88; P = 0.004. Conclusion. High levels of serum alkaline phosphatase, hypercalcaemia, and white race are associated with increased risk of death in MHD patients.

    Vascular access-related complications are a frequent cause of morbidity in haemodialysis patients and generate high costs. We present the case of an adult patient with end-stage renal disease and recurrent vascular access thrombosis associated with the prothrombin mutation G20210A and renal graft intolerance. The clinical expression of this heterozygous gene mutation may have been favoured by inflammatory state, frequent in dialysis patients. In this patient, the inflammatory response associated with the renal graft intolerance would have favored the development of recurrent vascular access thrombosis in a adult heterozygous for prothrombin mutation G20210A. In the case of early dysfunction of haemodialysis vascular access and after ruling out technical problems, it is convenient to carry out a screening for thrombophilia.

    Marital status is an important social factor associated with increased mortality from cardiovascular disease (CVD) and all causes. However, there has been no study on the association of marital status with mortality in haemodialysis patients. We analysed data from a 5-year prospective cohort study of 1064 Japanese haemodialysis patients aged 30 years or older. Marital status was classified into three groups: married, single and divorced/widowed. Cox's regression was used to estimate multivariate hazard ratios (HRs) [95% confidence intervals (CIs)] for all-cause mortality and CVD mortality according to marital status after adjusting for age, sex, duration of haemodialysis, cause of renal failure, body mass index, systolic blood pressure, total cholesterol, high density lipoprotein-cholesterol, albumin, high-sensitivity C-reactive protein, co-morbid conditions, smoking, alcohol consumption, education levels and job status. Single patients had higher risks than married patients for mortality from all causes (HR = 1.51, 95% CI: 1.06-2.16) and mortality from CVD (HR = 1.68, 95% CI: 1.03-2.76), and divorced/widowed patients had a higher risk than married patients for mortality from CVD (HR = 1.73, 95% CI: 1.15-2.60). After stratification by age, single patients aged 30-59 years had significantly higher risks for all-cause mortality and CVD mortality. The findings suggest that single status is a significant predictor for all-cause mortality and CVD mortality and that divorced/widowed status is a significant predictor for CVD mortality in haemodialysis patients.

    Protein-energy wasting (PEW), associated with inflammation and overhydration, is common in haemodialysis (HD) patients and is associated with high morbidity and mortality. Assess the relationship between nutritional status, markers of inflammation and body composition through bioimpedance spectroscopy (BIS) in HD patients. This observational, cross-sectional, single centre study, carried out in an HD centre in Forte da Casa (Portugal), involved 75 patients on an HD programme. In all participating patients, the following laboratory tests were conducted: haemoglobin, albumin, C-reactive protein (CRP) and 25-hydroxyvitamin D3 [25(OH)D3]. The body mass index of all patients was calculated and a modified version of subjective global assessment (SGA) was produced for patients on dialysis. Intracellular water (ICW) and extracellular water (ECW) were measured by BIS (Body Composition Monitor®, Fresenius Medical Care®) after the HD session. In statistical analysis, Spearman's correlation was used for the univariate analysis and linear regression for the multivariate analysis (SPSS 14.0). A P value of nutritional and inflammatory status of HD patients. BIS may be a useful tool for regularly assessing the nutritional and hydration status in these patients and may allow nutritional advice to be improved and adjusted.

Median serum iPTH level decreased by 30% after initiation of Mimpara in 94.3% patients, from them by 50%in 74.3%. Achieved the KDOQI treatment targets for PTH in 28.6% patients.In 6 months after PTx median serum iPTH level was <100 pg/ml in 50% patients, achieved the KDOQI treatment targets in 27.3%, <300 pg/ml in 18.2%. Median serum 25(ОНD after PTx significantly increase by 127.3% vs 6.72% in the Mimpara group. In 6 months active restoration of BMD was found in the PTx patients, and patients treated with Cinacalcet showed stabilization of BMD.Mimpara therapy led to a reduction in glandular volume during the course of the study: in both glands with a baseline volume <500 mm3 and with a baseline volume ≥500 mm3. Conclusions. PTx and Cinacalcet therapy improves phosphorus=calcium homeostasis, bone turnover, but bone resorption and formation

    Fatigue and quality of sleep are the main factors that contribute to a poor quality of life among patients on long-term haemodialysis. Studies have also emphasised the importance of exercise for improving the wellbeing of dialysis patients. This study aimed to determine the effectiveness of a predialysis low-to-moderate-intensity exercise programme for reducing fatigue and improving sleep disorders among long-term haemodialysis patients. In this quasi-experimental study, an exercise programme was conducted three times a week for 12 weeks before long-term haemodialysis patients underwent dialysis at two centres. The patients were categorised into either the exercise group (n = 28) or control group (n = 27). The latter was asked to maintain their current lifestyles. Assessments of fatigue and sleep disorder levels were performed for both groups using self-reported questionnaires at baseline and after intervention. The patients' perception of the exercise programme was also determined using self-reported questionnaires. Paired sample t-test indicated improvements in fatigue level in the exercise group (mean fatigue score: post-treatment 40.5 ± 7.9 vs. pre-treatment 30.0 ± 10.9). Improvements in sleep disorders were also observed in the exercise group (mean score: post-treatment 7.6 ± 3.3 vs. pre-treatment 10.1 ± 3.8). However, sleep quality deteriorated in the control group (mean score: post-treatment 10.7 ± 2.9 vs. pre-treatment 9.3 ± 2.9). Simple low-to-moderate-intensity exercise is effective for improving fatigue, sleep disorders and the overall quality of life among haemodialysis patients.

    Waste products of metabolism accumulate in patients with chronic kidney disease, and require clearance by haemodialysis (HD). We wished to determine whether there was an association between resting energy expenditure (REE) and total energy expenditure (TEE) in HD patients and body composition. We determined REE by recently validated equations (CKD equation) and compared REE with that estimated by standard equations for REE, and TEE calculated from patient reported physical activity, in HD patients with corresponding body composition measured by dual energy X-ray absorptiometry (DEXA) scanning. We studied 107 patients, 69 male (64.5%), mean age 62.7 ± 15.1 years. The CKD equation REE was 72.5 ± 13.3 watts (W) and TEE 83.2 ± 9.7 W. There was a strong association between REE with body surface area (BSA) (r2 = 0.80), total soft lean and fat lean tissue mass (r2 = 0.69), body mass index (BMI) (r2 = 0.34), all pequations underestimated REE compared to the CKD equation. TEE was more strongly associated with BSA (r2 = 0.51), appendicular muscle mass (r2 = 0.42), than BMI (r2 = 0.15) all pequations underestimate REE in HD patients compared to the CKD equation. TEE was greater in those with more skeletal muscle mass, in those who were employed and in those with the least co-morbidity. More metabolically active patients may well require greater dialytic clearances.

    The PIBHE study, promoted by the Spanish Liver and Kidney Association and the Dialysis Virus Group of the Spanish Society of Nephrology, is the first study to determine the status of haemodialysis patients with chronic HBV infection and the immunisation against the vaccine. The study has a national multicentre, observational, cross-sectional design and was carried out between January 2013 and 2014. A data collection folder was sent to all the nephrology departments and outpatient haemodialysis units in Spain, to be completed based on patient medical files after informed consent. The data were recorded in a central database. A total of 215 centres participated (15,645 patients), with an HBV prevalence of 1.03%. HCV or HIV was present in 7.2% of the HBV(+) patients. Viral load was below 2,000 IU/ml in 80%. GOT and GPT levels were 19.1±10.1 and 15.9±9.6 IU/ml, respectively. Liver biopsy was performed in 7.1%. Antiviral treatment was prescribed in 30% and suspended in 12.5%: entecavir (13.3%), lamivudine (10%), adefovir and tenofovir (6.7%), and interferon (3.3%). A total of 34.5% were candidates for renal transplantation and 6.9% had not been evaluated; 64.3% were followed up by a gastroenterologist; 27.2% of HBV(-) patients without immunisation had not been vaccinated. Fourteen different immunisation schedules had been used, with an immunisation rate of 58.8%. Mean anti-HBs stood at 165.7±297.8mIU/ml. A total of 72.7% of patients had received a vaccination course; 26.4%, 2 cycles; 1.0%, 3 cycles; and 11.6%, a booster dose. A total of 28.3% had a poor response (anti-HBs 10-99mIU/ml); 22.4%, an optimal response (anti-HBs 100-999mIU/ml); and 7.9%, an excellent response (anti-HBs ≥ 1,000mIU/ml). Age was significantly associated with response to vaccination; the mean age of nonresponders was significantly higher than patients who had a response of any kind (P<.05). The highest probability of an immune response was achieved with 4 doses of 40 mcg of adjuvanted vaccine

    Patients with end-stage kidney disease receiving haemodialysis (HD) are at risk of cardiovascular disease and bone disorders related to high levels of serum phosphate. We studied the association between medication beliefs and depressive symptoms, with non-adherence to phosphate binding medication in a group of HD patients at risk of complications due to hyperphosphatemia. Cross-sectional design. Baseline data from 112 patients participating in a randomized controlled trial, evaluating an adherence intervention, are presented. All patients had serum phosphate levels >1.6 mmol/l at baseline. Adherence was measured by (1) serum phosphate and (2) Medication Adherence Report Scales (MARS). Beliefs about Medicines (BMQ) and depressive symptoms (PHQ-9) were also evaluated. Beliefs about Medicines Questionnaire necessity, but not concerns, beliefs were found to correlate with serum phosphate (r = -.23, p adherence (r = .35, p adherence (β = .30, p ≤ .01). Both BMQ concerns and depressive symptoms were not related to non-adherence. Patients' beliefs about the necessity of their prescribed phosphate binding medications explain variation in non-adherence levels, measured both subjective and objectively. Dialysis patient's medication beliefs are potentially modifiable targets for future interventions. © 2014 The British Psychological Society.

    Hepatitis C infection is a worldwide problem. The global prevalence of the hepatitis C virus (HCV) averages 3%. Moreover, its prevalence among patients undergoing haemodialysis (HD) varies worldwide, ranging from as low as 1% to up to 70%. There are few data on its prevalence in developing countries, and even less information is available on HD patients. A literature review revealed that the prevalence of HCV infection among patients undergoing HD in Latin America ranges from 4.2 to 83.9%, with most data stemming from Argentina, Brazil, Mexico, Peru, Chile, Venezuela and Cuba. The most common genotype was genotype 1, and subtype 1b was the most frequent. The risk factors associated with this condition were the duration of the HD treatment and blood transfusion before hepatitis C screening. In addition, HCV RNA detection by polymerase chain reaction is crucial for the diagnosis of HCV infection in HD patients. Trials using combinations of new oral antiviral drugs, such as sofosbuvir and combo (ombitasvir, paritaprevir, ritonavir and dasabuvir), should be the next step in the improvement of care among HD patients with HCV, because these therapeutic agents apparently do not require dose adjustment according to renal function. Finally, information on this subgroup of patients remains unavailable in some countries; therefore, additional studies are needed to determine the prevalence trend of HCV infection in these populations.

    Recirculation is an important issue in haemodialysis (HD) patients as increased percent recirculation causes decreased dialysis delivery of the patients. The purpose of the study was to determine the amount and factors of recirculation in those patients. The study was a cross sectional one carried in the Department of Nephrology, Dhaka Medical College and Hospital during October 2010 to September 2011. A total of 118 end stage renal disease patients with arterio-venous fistula who were on HD for more than 3 months were purposively selected. The degree of recirculation was measured with urea based two needle technique method. For each patient distances between arterial and venous and distances of needles from fistula and its directions were recorded. Echocardiography and A-V fistula Colour Doppler Ultrasound were also performed. The mean A-V fistula recirculation was 8.1 +/- 5.5% with a range 0-66%. The most common factors were close proximity and improper arterial and venous needles placement. No difference was observed between diabetic and non diabetic also between hypertensive and normotensive. A-V fistula recirculation is common occurrence in HD patients and the most common factors of recirculation are misplacement and close proximity of needles therefore emphasis should be given on education and training of HD staffs.

    Full Text Available Hyperhydration, the sum of persistent (PH and intermittent (IH ones is the strong predictor of mortality in patients on program haemodialysis (PHD. The aim of this research was to investigate the complex of methods for minimization of PH as well as IH. Materials and methods. The bioimpedance multifrequency analysis (BIA, relative blood volume (RBV monitoring and plasma conductivity evaluation by ionic dialysance device were performed in candidates for kidney transplantation. Results. In 380 PHD patients, comparing with 26 healthy persons the expansion of extracellular volume was only observed even in the cases of the huge (3.5–15 L overload. PH of more than 15% of extracellular volume was observed in 41% of patients. The deviation of hydration status from reference value was 3.7 ± 1.4 L at first measurement and 1.9 ± 1.2 L at last one in every patient. RBV decreased insignificantly (less than 2.5% / L ultrafiltration during PHD sessions in patients with PH. This value increased after dry weight consummation and it appeared as surrogate of intravascular refueling capacity. The minimization of sodium dialysate – plasma gradient resulted in decrease of IH. Conclusion. The elimination of both PH and IH in PHD patients is the paramount goal; it demands the complex approaches and further investigations. 

  19. A 12-year review of Staphylococcus aureus bloodstream infections in haemodialysis patients: more work to be done.

    Staphylococcus aureus bloodstream infections (BSI) are a significant cause of morbidity and mortality in haemodialysis patients. This study describes a 12-year retrospective review of S. aureus BSI in a large haemodialysis centre in a tertiary referral hospital. The overall rate of S. aureus BSI was 17.9 per 100 patient-years (range 9.7-36.8). The rate of meticillin-resistant S. aureus (MRSA) BSI was 5.6 per 100 patient-years (range 0.9-13.8). Infective complications occurred in 11% of episodes, the most common being infective endocarditis (7.6%). Ten percent of patients died within 30 days of S. aureus being isolated from blood. Most cases of S. aureus BSI (83%) were related to vascular catheters. The provision of lower-risk vascular access, such as arteriovenous fistulae, and reduced use of intravascular catheters should be priorities in all haemodialysis units. Where alternative vascular access cannot be established, interventions to reduce the risk of catheter-related infections should be implemented to reduce morbidity and mortality in this vulnerable patient group.

    Evidence points to activation of pro-inflammatory and pro-thrombotic stimuli during the haemodialysis process in end-stage renal disease (ESRD) with potential to predispose to cardiovascular events. Diabetes is associated with a higher incidence of cardiovascular disease in haemodialysis patients. We tested the hypothesis that a range of mediators and markers that modulate cardiovascular risk are elevated in haemodialysis patients with diabetes compared to those without. Men and women with diabetes (n = 6) and without diabetes (n = 6) aged 18-90 years receiving haemodialysis were recruited. Blood samples were collected and analysed pre- and post-haemodialysis sessions for (platelet-monocyte conjugates (PMC), oxidised LDL (Ox-LDL), endothelin 1 (ET-1) and vascular endothelial growth factor (VEGF-A). PMC levels significantly increased after haemodialysis in both groups (diabetes p = 0.047; non-diabetes p = 0.005). Baseline VEGF-A was significantly higher in people with diabetes (p = 0.009) and post-dialysis levels were significantly reduced in both groups (P = 0.002). Ox-LDL and CRP concentrations were not significantly different between groups nor affected in either group post-dialysis. Similarly, ET-1 concentrations were comparable in all patients at baseline, with no change post-dialysis in either group. In this pilot study, we have confirmed that circulating PMCs are increased following dialysis irrespective of diabetes status. This is likely to be a mechanistic process and offers a potential explanation for high rates of vascular events associated with haemodialysis. The higher VEGF-A concentrations between patients with and without diabetes is a previously unreported finding in diabetic ESRD. Further research is merited to establish whether VEGF-A is a marker or mediator (or both) of cardiovascular risk in haemodialysis.

    To assess the relationship between sleep quality, daytime sleepiness and health-related quality-of-life (HRQoL) in Chinese patients undergoing maintenance haemodialysis (MHD). This cross-sectional study enrolled patients undergoing MHD. Self-reported sleep quality (Pittsburgh Sleep Quality Index [PSQI]), daytime sleepiness (Epworth Sleepiness Scale [ESS]) and HRQoL (36-item Short Form [SF-36]) were recorded for all patients. Sixty eight patients (mean ± SD age = 61.75 ± 16.56 years; 43 male/25 female) who regularly received MHD were included. The prevalence of poor sleepers was 69.1% (47/68) and daytime sleepiness was 11.8% (eight of 68). Poor sleepers had a significantly lower Physical Component Scale (PCS) score, Mental Component Scale (MCS) score and total SF-36 score than good sleepers. The PSQI score correlated inversely with both the PCS and MCS scores and correlated positively with age. Independent variables associated with total SF-36 score were duration of MHD, ESS score and PSQI score. Poor sleep quality is a common and severe issue for MHD patients in east China. Both sleep quality and daytime sleepiness were associated with lower HRQoL scores. © The Author(s) 2016.

    Ever since peritoneal dialysis (PD) was introduced as a form of renal replacement therapy, its efficacy and complications have been compared with that of haemodialysis (HD). The aim of this study was to determine the efficacy and outcome of PD in comparison to HD in our region. We compared 60 patients on PD with 60 matched patients on HD in Tabriz's Sina Hospital during the period 2004-2006. The technique, patients' survival and quality of life were compared by means of a health-related quality-of-life questionnaire (GHQ-28). There was no significant difference in the mean age and duration of dialysis between patients on PD and HD. Survival of diabetic patients was better with HD than PD, but in non-diabetic patients, there was no difference in the survival rates between the two groups. Among patients on PD, diabetics had a 25 percent higher mortality rate and non-diabetic patients had a three percent higher mortality rate than their corresponding counterparts on HD. In all four axes of the questionnaire, i.e. psychophysical dysfunction, stress and sleep disorders, social dysfunction and major depression, PD patients had lower scores than HD patients (p-values are less than 0.001, less than 0.001, equal to 0.002 and less than 0.001, respectively), indicating that patients on PD had a better quality of life compared to those on HD. In this study, technique, patients' survival and their quality of life were better on PD than on HD. However, survival and mortality of diabetic patients on HD were better than those on PD.

    This study was intended to examine the efficacy of lavender essential oil for the alleviation of fatigue in haemodialysis patients. This randomized clinical trial was conducted on 59 haemodialysis patients in two groups. The routine care group received the routine care, but the experimental group inhaled lavender essence 5% for 10 min, three times a week for 4 consecutive weeks. The Fatigue Severity Scale was used to assess fatigue before the intervention and after the last intervention in the second and fourth weeks. No statistically significant differences were observed between the two groups in terms of the fatigue scores before, and after the last intervention in the second and fourth weeks. Our result does not support other studies suggesting that lavender essential oil is effective on fatigue in haemodialysis patients. This conflicting result can mostly be ascribed to a variety of factors such as duration of aromatherapy and differences in concentrations of lavender essential oil. Copyright © 2015 Elsevier Ltd.

    Albumin-kinetic studies were performed in nine uraemic patients without oedema on chronic haemodialysis and in seven normal controls in order to determine microvascular leakiness and thereby, during steady state, lymph drainage of albumin. Transvascular escape rate of albumin [TERalb i.......e. the fraction of intravascular mass (IVMalb) passing into, or returning from, the extravascular space per unit time] and the distribution ratio (DRalb) between IVMalb and total albumin mass were determined from intravenously injected radioiodinated serum albumin. Before haemodialysis, TERalb was significantly...... elevated (mean 9 X 6% IVMalb h-1, range 5 X 9-14) as compared to the value 15 h after haemodialysis (mean 7 X 3, range 5 X 2-11, P less than 0 X 02) and to controls (mean 5 X 9, range 4 X 3-7 X 4, P less than 0 X 01). Average DRalb (mean 0 X 54, range 0 X 44-0 X 69) was clearly elevated in patients...

    Full Text Available Objective. Uraemic tumoral calcinosis refers to metastatic calcifications that occur rarely on the extensor surfaces of joints in patients undergoing long-term haemodialysis. The aim of the study was to assess the incidence of uraemic tumoral calcinosis in participants undergoing haemodialysis and to investigate any relationship that might exist between the development of uraemic tumoral calcinosis and the length of time on dialysis. Design. Twenty-four of the 25 patients on haemodialysis at the time of the study underwent radiographs of their shoulders and hips to look for calcinosis, which were then read by the researcher and two independent readers to assess for calcinosis. Study setting. Dr George Mukhari Hospital, Pretoria. Results. Eight per cent (N=2 of participants were found to have asymptomatic calcinosis of the hips. No relationship to length of time on dialysis was found. Conclusions. The study was constrained by a small sample size but the presence of calcinosis in 8% of the participants indicates that an extensive study of a larger sample could prove to be useful in determining the true incidence of uraemic tumoral calcinosis in the region. Long-term follow-up could provide more information on the development of calcinosis and length of time on dialysis.

    Several parameters might indicate protein-energy wasting in patients undergoing haemodialysis (HD), and such depletion has been associated with the survival of these patients. Our aim was to identify the parameters that are associated with an increased risk of death among HD patients. This was a prospective study with at least 13 months follow-up three times per week of 138 HD patients; 61.6% of the patients were men, 28.9% had diabetes mellitus, and 81.9% had hypertension. The associations of the survival rates based on by Kaplan-Meier analysis with the following nutritional parameters were verified: albumin, lymphocytes, % fat mass (% FM), mid-arm muscle circumference (MAMC), subjective global assessment (SGA), malnutrition-inflammation score (MIS), and nutritional risk screening 2002 (NRS 2002). Cox proportional hazard analysis was used to identify the patients' risk of death (hazard proportional ratio - HR). The nutritional parameters of lymphocytes and % FM were not associated with the risk of patient death. The patients who were classified as malnourished based on MAMC had a greater risk of death than did those considered nourished, but this difference was not statistically significant. The parameters of serum albumin, SGA, MIS, and NRS 2002 were associated with the risk of patient death (HR = 2.77 P = 0.042, HR = 1.88 P = 0.202, HR = 4.47 P = 0.011, HR = 3.13 P = 0.022, respectively), and the latter two parameters were significantly associated with a high risk among malnourished. The scores for the MIS and NRS 2002 composite methods of nutritional assessment were associated with the highest mortality risk values; thus, in conditions similar to those of our study, we suggest that the use of these parameters should be preferred.

    Complementary and alternative medicine (CAM), and herbal therapies, are accepted worldwide, and have been important from medical, sociological and economic perspectives, among haemodialysis (HD) patients. The primary aim of this study was to evaluate the use of CAM among patients with end-stage renal disease (ESRD) who are undergoing HD. Face-to-face interviews of patients with ESRD undergoing HD from ten outpatient renal departments at a national level in Palestine were conducted from June 2014 to January 2015. A survey questionnaire, which included questions on socio-demographic and clinical characteristics, and on the CAM therapies that were used, was administered. Out of 267 patients interviewed, 172 patients used at least one type of CAM in the last month prior to the interview, and thus the utilisation rate was 64.4 %. Forty one (15.4 %) patients reported using one type of CAMs, while 18.7 % used two different CAMs and 30.3 % used more than two types of CAMs for their health status. Of the patients who used CAM, herbal therapies were used most often (43.5 %), followed by honey (35.6 %), diet (22.8 %), and exorcism in Islam (16.9 %). The herbal therapies mentioned most often were Nigella sativa L. (18.7 %), followed by Salvia officinalis L. (16.9 %), and Pimpinella anisum L. (10.5 %). In conclusion, the prevalence of CAM is relatively high in the selected population. Most patients used biological therapies such as herbal remedies, thus highlighting a greater need for patient education regarding CAM therapies and possible herb-drug interactions. Health care providers must be aware of the potential benefits and risks related to CAM use. There is a need for more clinical research pertaining to CAM to reach stronger evidence regarding potential benefits and risks related to CAM use.

    Atrial fibrillation (AF) represents an important social and healthcare problem. There is wide variability in the prevalence of this arrhythmia in studies analysing patients on haemodialysis (HD). To investigate the prevalence, clinical profile and therapeutic management of patients with AF on HD in Andalusia. We asked the public healthcare system of Andalusia to provide us with the number of patients who were being treated with HD. We asked attending nephrologists from all hospital and outpatient centres in 5 of the 8 Andalusian provinces to perform an electrocardiogram and to fill out a questionnaire on patients selected by simple random sampling. A total of 2,348 patients were being treated with HD in the 5provinces included in the study. The estimated sample size was 285 patients. We obtained an electrocardiogram and information from 252 patients (88.4%); mean age 65.3±16 years; 40.9% women. Sixty-three patients (25%) had AF. Of these, 36 (14.3%) had AF in the recorded ECG and in the rest it had been documented previously. In the multivariate analysis, older age (OR: 1.071; 95% CI: 1.036-1.107; P=0.000) and greater time on HD (OR: 1.009; 95% CI: 1.004-1.014; P=0.000) were independently associated with the presence of AF. Of the patients with AF, 41.3% were on anticoagulant treatment at the time of the study; and 41.2% were on antiplatelet agents. AF in dialysis units is an important finding. Establishing the risk-benefit ratio of anticoagulant treatment constitutes a real challenge. Well-designed clinical trials are pivotal in order to define the rational use of antithrombotic drugs.

    Haemodialysis (HD) is a life-sustaining treatment for patients with end-stage renal disease (ESRD). HD can bring about significant impairment in health-related quality of life (HRQOL) and outcomes. Therefore, we sought to describe the patterns of HRQOL and determine the independent factors associated with poor HRQOL in Palestinian patients on HD. A multicenter cross-sectional study was performed from June 2014 to January 2015 using the EuroQOL-5 Dimensions instrument (EQ-5D-5L) for the assessment of HRQOL. ESRD patients undergoing HD in all dialysis centres in the West Bank of Palestine were approached and recruited for this study. Multiple linear regression was carried out to identify factors that were significantly associated with HRQOL. Two hundred and sixty-seven patients were participated in the current study giving response rate of 96 %. Overall, 139 (52.1 %) were male, and the mean ± standard deviation age was 53.3 ± 16.2 years. The reported HRQOL as measured by mean EQ-5D-5L index value and Euro QOL visual analogue scale (EQ-VAS) score was 0.37 ± 0.44 and 59.38 ± 45.39, respectively. There was a moderate positive correlation between the EQ-VAS and the EQ-5D-5L index value (r = 0.42, p live in village. Our results provided insight into a number of associations between patient variables and their HRQOL. Healthcare providers should be aware of low HRQOL among patients with no formal education, female gender, patient's residents of refugee camps, multiple co-morbid diseases, multiple chronic medications, and elderly patients to improve their quality of life.

    Little is known about patients' and carers' experiences of interacting with home haemodialysis (HHD) technology, in terms of user experience, how the design of the technology supports safety and fits with home use, and how the broader context of service provision impacts on patients' use of the technology. Data were gathered through ethnographic observations and interviews with 19 patients and their carers associated with four different hospitals in the UK, using five different HHD machines. All patients were managing their condition successfully on HHD. Data were analysed qualitatively, focusing on themes of how individuals used the machines and how they managed their own safety. Findings are organised by three themes: learning to use the technology, usability of the technology, and managing safety during dialysis. Home patients want to live their lives fully, and value the freedom and autonomy that HHD gives them; they adapt use of the technology to their lives and their home context. They also consider the machines to be safe; nevertheless, most participants reported feeling scared and having to learn through mistakes in the early months of dialysing at home. Home care nurses and technicians provide invaluable support. Although participants reported on strategies for anticipating problems and keeping safe, perceived limitations of the technology and of the broader system of care led some to trade off safety against immediate quality of life. Enhancing the quality and safety of the patient experience in HHD involves designing technology and the broader system of care to take account of how individuals manage their dialysis in the home. Possible design improvements to enhance the quality and safety of the patient experience include features to help patients manage their dialysis (e.g. providing timely reminders of next steps) and features to support communication between families and professionals (e.g. through remote monitoring).

    Vascular calcification (VC) and accelerated atherosclerosis are major causes of cardiovascular (CV) morbidity and mortality in haemodialysis (HD) patients. Inhibitory proteins are associated with reduced VC and may play a key role in preventing CV in chronic kidney disease (CKD) patients. Fetuin-A, also known as alpha(2)-Heremans-Schmid glycoprotein (AHSG), is a circulating plasma protein with inhibitory effects on VC that has been associated with inflammation and CV mortality in HD patients. In the present study, we investigated the associations between serum fetuin-A levels and its gene (AHSG) polymorphisms in an Italian HD population. Ninety-six patients on stable chronic HD treatment and 57 healthy controls were genotyped for the common polymorphisms on the AHSG (T256S). In addition, serum fetuin-A levels were tested. In this study, serum fetuin-A levels were lower in HD patients (0.35 +/- 0.11 g/l) compared with healthy controls (0.62 +/- 0.31 g/l, p AHSG gene did not show significant association between low serum fetuin-A levels and the Ser/Ser genotype, known to be associated with a higher CV mortality risk in the HD population. Moreover, the distribution of AHSG gene polymorphisms in HD patients and in healthy controls was similar. In contrast with previous reports, this study suggests that CKD patients on HD treatment have a similar polymorphism distribution of the AHSG gene compared with the normal population and that the reduction in serum fetuin-A levels in Italian HD patients is not associated with an alteration in the distribution of AHSG T256S polymorphisms.

    Anti-parathyroid treatment initiation and discontinuation are important decisions in chronic haemodialysis (HD) patients, where pill burden is often excessive. The present study aimed to describe secondary hyperparathyroidism (sHPT) drug therapy changes in HD patients. Retrospective observational cohort study of incident European HD patients with sHPT who were prescribed calcitriol or alfacalcidol (alpha calcitriol), paricalcitol or cinacalcet. Treatment-naïve patients prescribed alpha calcitriol (N=2259), paricalcitol (N=1689) and cinacalcet (N=1245) were considered for analysis. Serum intact parathyroid hormone (iPTH) levels decreased post-initiation with all treatment modalities; serum calcium and phosphate levels increased in response to activated vitamin D derivatives but decreased with cinacalcet. Approximately one-third of alpha calcitriol and paricalcitol patients but less than one-quarter of cinacalcet patients discontinued treatment. Although the three groups had comparable serum iPTH control at the time of treatment discontinuation, they differed in terms of calcium and phosphate levels. Following discontinuation, the evolution of laboratory parameters differed by treatment modality: whilst iPTH increased for all three treatment groups, calcium and phosphate decreased in patients who were being treated with alpha calcitriol and paricalcitol at the time of discontinuation, and increased in those who had been treated with cinacalcet. In conditions of daily clinical practice, attaining and maintaining recommended biochemical control of sHPT appears to be more frequently achievable with cinacalcet than with activated vitamin D compounds.

    Poor nutritional status and worse healthrelated quality of life (QoL) have been reported in haemodialysis (HD) patients. The utilization of generic and disease specific QoL questionnaires in the same population may provide a better understanding of the significance of nutrition in QoL dimensions. To assess nutritional status by easy to use parameters and to evaluate the potential relationship with QoL measured by generic and disease specific questionnaires. Nutritional status was assessed by subjective global assessment adapted to renal patients (SGA), body mass index (BMI), nutritional intake and appetite. QoL was assessed by the generic EuroQoL and disease specific Kidney Disease Quality of Life-Short Form (KDQoL-SF) questionnaires. The study comprised 130 patients of both genders, mean age 62.7 ± 14.7 years. The prevalence of undernutrition ranged from 3.1% by BMI ≤ 18.5 kg/m² to 75.4% for patients below energy and protein intake recommendations. With the exception of BMI classification, undernourished patients had worse scores in nearly all QoL dimensions (EuroQoL and KDQoL-SF), a pattern which was dominantly maintained when adjusted for demographics and disease-related variables. Overweight/ obese patients (BMI ≥ 25) also had worse scores in some QoL dimensions, but after adjustment the pattern was maintained only in the symptoms and problems dimension of KDQoL-SF (p = 0.011). Our study reveals that even in mildly undernourished HD patients, nutritional status has a significant impact in several QoL dimensions. The questionnaires used provided different, almost complementary perspectives, yet for daily practice EuroQoL is simpler. Assuring a good nutritional status, may positively influence QoL.

    Objectives To investigate the incidence rates and risk factors for catheter-related complications in different districts and populations in Henan Province in China. Design Cross-sectional. Setting Fourteen hospitals in Henan Province. Participants 865 patients with renal dysfunction undergoing dialysis using catheters between October 2013 and October 2014. Main outcome measures The main outcome measures were complications, risk factors and patient characteristics. Catheter-related complications included catheter-related infection (catheter exit-site infection, catheter tunnel infection and catheter-related bloodstream infection), catheter dysfunction (thrombosis, catheter malposition or kinking, and fibrin shell formation) and central vein stenosis. Results The overall incidence rate was 7.74/1000 catheter-days, affecting 38.61% of all patients, for catheter infections, 10.58/1000 catheter-days, affecting 56.65% of all patients, for catheter dysfunction, and 0.68/1000 catheter-days, affecting 8.79% of all patients, for central vein stenosis. Multivariate analysis showed that increased age, diabetes, primary educational level or below, rural residence, lack of a nephropathy visit before dialysis and pre-established permanent vascular access, not taking oral drugs to prevent catheter thrombus, lower serum albumin levels and higher ferritin levels were independently associated with catheter infections. Rural residence, not taking oral drugs to prevent thrombus, lack of an imaging examination after catheter insertion, non-tunnel catheter type, lack of medical insurance, lack of nephropathy visit before dialysis and pre-established permanent vascular access, left-sided catheter position, access via the femoral vein and lower haemoglobin level were independently associated with catheter dysfunction. Diabetes, lack of nephropathy visit before dialysis and pre-established permanent vascular access, lack of oral drugs to prevent catheter thrombus, left-sided catheter

    Full Text Available Hyperphosphatemia in haemodialysis (HD patients is associated with mineral and bone disorder and increased cardiovascular disease. Despite dietary restriction of phosphorous (P, improved dialysis therapy and phosphate binders (PB, hyperphosphatemia remains a serious problem among the dialysis population. A sub-optimal relationship between the actual dietary intake of P and the intake of PB’s may be one explanation. The aim of the present study was to investigate the dietary P intake in a group of HD patients in relation to the taken dosage of PB, and to establish what, if any, relationship exists with the patients’ plasma phosphate level. Self-reported intake of P, assessed by three-day estimated food record, and intake of PB was analysed in thirty-one adult (age 61.8±12.9 years HD patients (17 men, 14 women, who were divided into two groups according to their plasma P levels. The mean dietary P intake among all patients was 1270±420 mg/d with a mean day-to-day variation of 390±310 mg. The P intake in one single meal ranged from 1.6 mmol/l and low (<1.6 mmol/L plasma P levels were observed. In conclusion, the findings show a notable individual day-to-day and meal-to-meal variation in dietary P intake and in contradiction, the same individual dosing regimen of PB. Strangely, no significant difference in the dietary P intake or intake of PBs between HD patients with high or low plasma P level was found. The question of whether a PB intake better tailored to the meal and day variation in P intake could prevent hyperphosphatemia will need to be evaluated in further studies.

    Pregnancy-associated plasma protein-A (PAPP-A) is a putative marker of atheroma instability and ischaemic myocardial stress prior to necrosis. Total PAPP-A (tPAPP-A) levels in acute coronary syndromes predict adverse outcomes. However, free PAPP-A (fPAPP-A) predominates in the circulation. Ischaemic haemodialysis (HD)-induced cardiac injury (myocardial stunning) is common and is associated with markers of myocardial necrosis, inflammation, cardiovascular events and mortality. Coronary plaque instability in pathophysiology of HD-induced myocardial stunning has not been studied. We aimed to investigate the relationship of fPAPP-A with stunning and mortality. 130 prevalent patients from two HD centres (Finland and UK) were studied. Pre-HD free, complexed and total PAPP-A were measured by immunoassay. A subset of 62 patients underwent echocardiography to assess HD-induced myocardial stunning. The mean duration of follow-up was 407 ± 98 days. fPAPP-A was elevated (median: 3.45 mIU/l) and correlated with dialysis vintage (r = 0.391, p PAPP-A was not related to stunning. Dialysis vintage and cTnT independently predicted Ln fPAPP-A (model R = 0.463). fPAPP-A, cTnT and age independently predicted death (Nagelkerke R(2) = 0.362). fPAPP-A, a novel predictor of HD-related mortality, demonstrates better prognostic power than tPAPP-A. Coronary plaque instability may contribute to sub-lethal myocardial injury, but may not be critical in pathogenesis of HD-induced ischaemic cardiac injury.

    Aims The appropriate use of intravenous (IV) iron is essential to minimise the requirements for erythropoiesis-stimulating agents (ESAs). The clinical efficacy of generic IV iron compared to the original formulation is controversial. We evaluated the changes that were induced after switching from a generic IV iron to an original formulation in a stable, prevalent haemodialysis (HD) population. Methods A total of 342 patients were included, and the follow-up period was 56 weeks for each formulation. Anaemia parameters and doses of ESA and IV iron were prospectively recorded before and after the switch from generic to original IV iron. Results To maintain the same haemoglobin (Hb) levels after switching from the generic to the original formulation, the requirements for IV iron doses were reduced by 34.3% (from 52.8±33.9 to 34.7±31.8mg/week, p<0.001), and the ESA doses were also decreased by 12.5% (from 30.6±23.6 to 27±21μg/week, p<0.001). The erythropoietin resistance index declined from 8.4±7.7 to 7.4±6.7 IU/kg/week/g/dl after the switch from the generic to the original drug (p = 0.001). After the switch, the transferrin saturation ratio (TSAT) and serum ferritin levels rose by 6.8%(p<0.001) and 12.4%(p = 0.001), respectively. The mortality rate was similar for both periods. Conclusions The iron and ESA requirements are lower with the original IV iron compared to the generic drug. In addition, the uses of the original formulation results in higher ferritin and TSAT levels despite the lower dose of IV iron. Further studies are necessary to analyse the adverse effects of higher IV iron dosages. PMID:26322790

    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. 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. 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

    The purpose of this study was to evaluate the effects of 6 months of specific balance training included in endurance-resistance program on postural balance in haemodialysis (HD) patients. Forty-nine male patients undergoing HD were randomly assigned to an intervention group (balance training included in an endurance-resistance training, n = 26) or a control group (resistance-endurance training only, n = 23). Postural control was assessed using six clinical tests; Timed Up and Go test, Tinetti Mobility Test, Berg Balance Scale, Unipodal Stance test, Mini-Balance Evaluation Systems Test and Activities Balance Confidence scale. All balance measures increased significantly after the period of rehabilitation training in the intervention group. Only the Timed Up and Go, Berg Balance Scale, Mini-Balance Evaluation Systems Test and Activities Balance Confidence scores were improved in the control group. The ranges of change in these tests were greater in the balance training group. In HD patients, specific balance training included in a usual endurance-resistance training program improves static and dynamic balance better than endurance-resistance training only. Implications for rehabilitation Rehabilitation using exercise in haemodialysis patients improved global mobility and functional abilities. Specific balance training included in usual endurance resistance training program could lead to improved static and dynamic balance.

    High pulse rate is a culprit of all causes of death in the general population, but its relation to death in haemodialysis (HD) patients has not been examined in a large patient cohort. We examined the relationship between pulse rate (beats per minute, bpm) before an HD session and survival based on the nationwide HD registry of the Japanese Society for Dialysis Therapy. Outcomes were confirmed using the coded ID numbers of both 2005 and 2006 registries. Logistic analyses were performed to determine the effect of pre-HD pulse rate on survival. A total of 147,702 patients (50.5% men; 31.4% with diabetes mellitus; mean age 63.6 years) on HD three times weekly were studied. Mean (SD) pulse rate was 74.6 (12.0) bpm. The pulse rate distribution was as follows: 0.7% (40-49 bpm), 6.1% (50-59 bpm), 25.3% (60-69 bpm), 38.1% (70-79 bpm), 18.7% (80-89 bpm), 7.9% (90-99 bpm), 2.4% (100-109 bpm) and 0.7% (110-129 bpm). Overall 1-year mortality rate was 6.6%. Compared with the reference pulse rate (60-69 bpm), the odds ratio (95% CI) for 1-year mortality was 1.20 (0.88-1.63, NS: 40-49 bpm), 1.06 (0.93-1.21, NS: 50-59 bpm), 1.13 (1.04-1.22, P = 0.0037: 70-79 bpm), 1.46 (1.33-1.60, P bpm), 1.91 (1.70-2.15, P bpm), 2.61 (2.19-3.10, P bpm), and 2.43 (1.79-3.30, P bpm) after adjusting for age, sex, diabetes mellitus, body mass index, HD duration, serum albumin, haemoglobin, systolic blood pressure, medication for hypertension, and history of acute myocardial infarction. Survival rate decreased with an increase in the pre-HD pulse rate in chronic HD patients. The causality of this association and the reasons for a better annual mortality rate of 6.6% remain to be clarified.

    Low levels of thyroid hormones, total triiodothyronine (T3) and free triiodothyronine (FT3) in haemodialysis patients is a marker of malnutrition and inflammation and are predictors of mortality. The aim of this study was to determine the prevalence of malnutrition-inflammation complex syndrome in haemodialysis and its relationship with the thyroid hormones thyrotropin, T3, FT3 and free thyroxine (FT4), as well as to evaluate the prevalence of low FT3 syndrome and its correlation with nutritional and inflammatory markers. Cross-sectional, analytical and comparative study that enrolled 128 haemodialysis patients: 50.8% females; mean age 45.05±17.01 years; mean time on haemodialysis 45.4±38.8 months; 29.7% diabetics; 79.7% with hypertension. Serum thyroid hormones thyrotropin, T3, FT3 and FT4 concentrations were measured and Malnutritition-Inflammation Score (MIS) was applie to diagnostic. Mean thyroid hormone values were: thyroid hormones thyrotropin 2.48±1.8 mIU/ml (range: 0.015-9.5), T3 1.18±0.39 ng/ml (range 0.67-2.64), FT3 5.21±0.96pmol/l (range: 3.47-9.75); FT4 1.35±0.4 ng/ml (range: 0.52-2.57). Malnutrition-inflammation complex syndrome prevalence was 53.9%; 11.7% presented low FT3 levels. Serum T3 and FT3 concentrations inversely correlated with Malnutritition-Inflammation Score (MIS), while FT4 correlated positively with Malnutrition-Inflammation Score. In the linear regression analysis, low FT3 was associated with IL-6 (β= 0.265, p=.031), C-reactive protein (CRP) (β= -0.313, p=.018) and albumin (β= 0.276, p=.002). Low T3 and FT3 levels are correlated with malnutrition and inflammation parameters. Malnutrition-inflammation complex syndrome can affect serum concentrations of thyroid hormones.

    Diabetic patients with chronic kidney disease (CKD) frequently develop cardiac events within several years of the initiation of haemodialysis. The present study assesses the prognostic significance of stress myocardial ECG-gated perfusion imaging (MPI) in patients with diabetic CKD requiring haemodialysis. Fifty-five asymptomatic patients with diabetic stage V CKD and no history of heart disease scheduled to start haemodialysis were enrolled in this study (56{+-}11 years old; 49 with type 2 diabetes mellitus). All patients underwent {sup 201}Tl stress ECG-gated MPI 1 month before or after the initiation of haemodialysis to assess myocardial involvement. We evaluated SPECT images using 17-segment defect scores graded on a 5-point scale, summed stress score (SSS) and summed difference scores (SDS). The patients were followed up for at least 2 years (42{+-}15 months) to determine coronary intervention (CI) and heart failure (HF) as soft events and acute myocardial infarction (AMI) and all causes of deaths as hard events. The frequencies of myocardial ischaemia, resting perfusion defects, low ejection fraction and left ventricular (LV) dilatation were 24,20,29 and 49%, respectively. Ten events (18%) developed during the follow-up period including four CI, one HF, one AMI and four sudden deaths. Multivariate Cox analysis selected SDS (p=0.0011) and haemoglobin A{sub 1c} (HbA{sub 1c}) (p=0.0076) as independent prognostic indicators for all events. Myocardial ischaemia, in addition to glycaemic control, is a strong prognostic marker for asymptomatic patients with diabetic CKD who are scheduled to start haemodialysis. Stress MPI is highly recommended for the management and therapeutic stratification of such patients. (orig.)

    Psychological treatment of depression in end-stage renal disease (ESRD) has focused on severely depressed patients. We designed and tested a brief (5 weeks) cognitive behavioural intervention (CBI) to reduce mild and moderate depression and anxiety symptoms in patients with ESRD. For the purpose of this study, a single-blind, randomized controlled design was used to compare patients with ESRD under haemodialysis treatment with and without the CBI. Depression and anxiety symptoms were screened in 152 subjects (18-60 years old, 84 male). Sixty participants (age 41.8 ± 14.7, 29 males) with mild or moderate scores of depression (Beck Depression Inventory) and anxiety (Beck Anxiety Inventory) were randomly assigned to CBI or the control group. CBI techniques consisted of positive self-reinforcement, deep breathing, muscle relaxation, and cognitive restructuring. Depression, anxiety, quality of life (QoL), and cognitive distortion scores were evaluated at baseline, after 5 weeks (end of treatment) and after 4-week follow-up. All scores were compared by ANOVA for repeated measures with post-hoc tests adjusted by Bonferroni's method (p cognitive distortions had decreased, and QoL had increased in the intervention group, and there were no changes in the control group. Clinical utility was 33% for depression and 43% for anxiety. A brief CBI of 5 weeks is effective for decreasing mild or moderate depression and anxiety symptoms and improving QoL in ESRD haemodialysis patients. A brief, systematic and structured cognitive behavioural intervention (CBI) decreases anxiety and depression symptoms and improves quality of life in patients with end-stage renal disease (ESRD) who are being treated with haemodialysis. These benefits are not achieved when anxiety and depression symptoms are identified but not treated psychologically. This CBI consisted of cognitive restructuring of the distorted thoughts (perfectionism, catastrophic thinking, negative self-labelling, and

    Providing high-quality care to patients undergoing haemodialysis (HD) is a priority for nurses. The present study was conducted to explore the experiences of the quality of nursing care among patients, nurses, caregivers and physicians in an HD department in Iran. This was a qualitative study, set in the HD department of Kowsar Hospital in Semnan, Iran. A total of 20 participants (patients, caregivers, nurses and doctors) were selected and were invited to semi-structured interviews with open-ended questions. The data obtained were analysed using conventional content analysis. The analysis of the data led to the extraction of four themes: maintaining health, person/client, nursing responsibility and environment. The findings of the present study showed that maintaining health, person/client interaction, nursing responsibility and environment are four important nursing metaparadigms that affect the quality of nursing care in HD departments. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    While maintenance of both phosphorus concentration and nutritional status is a major concern in managing haemodialysis patients, the interaction between these parameters is not well understood. The aim of this study was to assess whether or not nutritional index influences the association between phosphorus concentration and all-cause mortality. A cohort study. The Dialysis Outcomes and Practice Pattern Study, which included 99 representative dialysis facilities in Japan between 1997 and 2010. A total of 6230 adult haemodialysis patients who had spent at least 6 months on haemodialysis. Six categories based on time-averaged factors of the geriatric nutritional risk index (GNRI; the lowest two and highest tertiles) and phosphorus concentration (risk due to interaction (RERI) between high phosphorus concentrations and low-middle GNRI was -0.57, indicating an antagonistic interaction. We also observed a significant statistical multiplicative interaction between phosphorus concentrations and GNRI (p=0.05 by likelihood ratio test). The association between time-averaged serum phosphorus concentration and all-cause mortality differs across the nutritional index. Accordingly, nutritional index should be considered when the impact of phosphorus concentration on mortality in haemodialysis patients is evaluated. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Streptococcus uberis, the most frequent cause of mastitis in lactating cows, is considered non-pathogenic for humans. Only a few case reports have described human infections with this microorganism, which is notoriously difficult to identify. We report the case of a 75-year-old male haemodialysis patient, who developed a severe foot infection with osteomyelitis and bacteraemia. Both Streptococcus uberis and Staphylococcus aureus were identified in wound secretion and blood samples using mass spectrometry. The presence of Streptococcus uberis was confirmed by superoxide dismutase A sequencing. The patient recovered after amputation of the forefoot and antibiotic treatment with ampicillin/sulbactam. He had probably acquired the infection while walking barefoot on cattle pasture land. This is the first case report of a human infection with Streptococcus uberis with identification of the microorganism using modern molecular technology. We propose that Staphylococcus aureus co-infection was a prerequisite for deep wound and bloodstream infection with Streptococcus uberis.

    Objective. Chronic uraemia is associated with abnormalities in skeletal muscles, which can affect their working capacity. It is also well known that the fibre-type composition of skeletal muscles influences endurance, muscle strength and power. In this study we therefore determined the size...... and distribution of muscle fibres and the myosin heavy-chain (MHC) isoform composition in patiens on haemodialysis (HD) in order to establish any differences with values for untrained control subjects. Material and methods. Muscle biopsies were obtained from the vastus lateralis muscle of 14 non-diabetic patients...... determined fibre-type composition of the vastus lateralis muscle. The mean fibre area of type 1 and 2 fibres was 3283±873 and 3594±1483 µm2, respectively. The MHC composition and the size of the type 1 fibres of the patients on HD were significantly different from those of the control subjects. Conclusions...

    The prevalence of depression in people receiving haemodialysis is high with estimates varying between 20 and 40 %. There is little research on the effectiveness of antidepressants in dialysis patients with the few clinical trials suffering significant methodological issues. We plan to carry out a study to evaluate the feasibility of conducting a randomised controlled trial in patients on haemodialysis who have diagnosed Major Depressive Disorder. The study has two phases, a screening phase and the randomised controlled trial. Patients will be screened initially with the Beck Depression Inventory to estimate the number of patients who score 16 or above. These patients will be invited to an interview with a psychiatrist who will invite those with a diagnosis of Major Depressive Disorder to take part in the trial. Consenting patients will be randomised to either Sertraline or placebo. Patients will be followed-up for 6 months. Demographic and clinical data will be collected at screening interview, baseline interview and 2 weeks, and every month (up to 6 months) after baseline. The primary outcome is to evaluate the feasibility of conducting a randomised, double blind, placebo pilot trial in haemodialysis patients with depression. Secondary outcomes include estimation of the variability in the outcome measures for the treatment and placebo arms, which will allow for a future adequately powered definitive trial. Analysis will primarily be descriptive, including the number of patients eligible for the trial, drug exposure of Sertraline in haemodialysis patients and the patient experience of participating in this trial. There is an urgent need for this research in the dialysis population because of the dearth of good quality and adequately powered studies. Research with renal patients is particularly difficult as they often have complex medical needs. This research will therefore not only assess the outcome of anti-depressants in haemodialysis patients with depression but

    Prevalence of HGV(GBV-C) infection and its coinfection with HBV a HCV infections were studied in group of 82 haemodialysis patients. This study was realized 20 months latter again -- 16 patients from 82 were running in dialysis, 17 patients were transplanted and 49 patients died (non of this viruses was cause of their death). HGV(GBV-C) RNA was detected in serum of 22 patients, 20 months latter it was detected in serum of 3 patients; one positive was new. 20 months latter any HGV(GBV-C) RNA was not detected in serum of 4 originally positive patients. Three of ten HBsAg positive patients were coinfected by HGV(GBV-C) RNA; 20 months latter any coinfection was found. In the first we found HGV(GBV-C) RNA in serum of 5 anti-HCV positive patients and in serum of 1 HCV RNA positive patient; 20 months latter it was in serum of 1 and 1 respectively. Elevation of ALT and AST levels were found in serum of 3 from 82 patients; two patients were coinfected with HBV or HCV. Any from 2 running dialysis patients with elevation of ALT and AST levels was not HGV(GBV-C) RNA positive. This virus is not probably frequent cause of liver disease in dialysis patients and it is not necessary to routinely screen for HGV(GBV-C) infection in this group of patients.

    Background Despite its importance, total body water (TBW) is usually estimated rather than measured due to the complexity of isotope dilution methods. The aim of this study was to demonstrate the applicability in haemodialysis (HD) patients of a recently developed on-line breath test, previously validated in healthy subjects, that uses the gold standard deuterium dilution method to measure TBW. In particular we wished to show that a pre-dialysis estimation was as good as a post dialysis equilibrated measurement in order to avoid patients needing to remain behind after dialysis treatment. Methods The dispersal kinetics of breath HDO, measured using a flowing-afterglow mass spectrometer (FA-MS) following ingestion of D2O immediately post-dialysis, were determined in 12 haemodialysis patients and used to calculate the absolute TBWPostHD after full equilibration. TBWPreHD was then determined from breath samples taken immediately prior to the next dialysis. This measurement was adjusted for the inter-dialytic weight change and urine output (TBWPreHD-adjusted) and compared to the TBWPostHD. The accuracy and precision of FA-MS was also assessed using known concentrations deuterium enriched water samples. Results Mean TBWPostHD was 50.0 ± 9.3 L and TBWPreHD-adjusted 50.7 ± 9.0 L. They were highly correlated (R= 0.99, pdeuterium equilibration kinetics identical to normal subjects; a pre-dialysis estimation may be used to determine TBW so avoiding the necessity to remain behind after dialysis making this suitable for application in the clinical setting.

    Levamisole as an immunomodulator drug has been demonstrated to improve the immune response to hepatitis B virus vaccination in haemodialysis patients. The aim of this randomized double-blind placebo-controlled trial was to evaluate the effect of levamisole supplementation on tetanus-diphtheria (Td) vaccine response rates in haemodialysis patients. Forty haemodialysis patients who had not received tetanus vaccination in a year before investigation and had unprotective anti-tetanus immunoglobulin G (IgG) levels (levamisole (100 mg) or placebo daily, for 6 days before and 6 days after vaccination. The anti-tetanus IgG levels were measured 1 and 6 months after vaccination. One month post-vaccination, four patients were excluded from the levamisole group and two from the placebo group because of either death or renal transplantation. At 1 month, 13 out of 16 (81%) patients in the levamisole group as compared with six out of 18 (33%) patients in the placebo group developed protective anti-tetanus IgG levels (relative risk = 2.44, 95% confidence interval (CI) = 1.21, 4.88). From 1 to 6 months post-vaccination, one more patient in the levamisole group and two more patients in the placebo group were excluded because of renal transplantation. At 6 months, 11 out of 15 (73%) patients in the levamisole group as compared with four out of 16 (25%) patients in the placebo group still had protective anti-tetanus IgG levels (relative risk = 2.93, 95% CI = 1.19, 7.23). Supplementation of Td vaccination with levamisole may enhance seroconversion against tetanus in haemodialysis patients. © 2013 Asian Pacific Society of Nephrology.

    Surveillance cultures for the demonstration of coagulase-negative staphylococci in patients on catheter haemodialysis were performed in an attempt to predict dialysis catheter-related septicaemia. In all, 43 patients with 67 haemodialysis catheters were followed for a 1-y period. Once a week, swab...... specimens were obtained from the skin at the insertion site and the hub, and blood cultures were obtained from the catheter. Among coagulase-negative staphylococci, S. epidermidis was the most frequently (80%) isolated species, and two biotypes accounted for 55.7% of the 41 biotypes isolated. 11 septicaemia...... cases due to coagulase-negative staphylococci occurred, all caused by S. epidermidis, and the incidence of S. epidermidis septicaemia was 21% among patients and 16% among catheter periods. S. epidermidis septicaemia occurred in 17%, 31% and 33% of all catheter periods in which S. epidermidis...

    In patients with end-stage renal disease (ESRD) treated with intermittent haemodialysis, a limited number of antibiotics have been studied for their suitability for parenteral administration after dialysis sessions only in a thrice-weekly regimen. Temocillin is a β-lactam antibiotic with a long half-live and enhanced activity against most Gram-negative bacteria, including extended-spectrum β-lactamase-producers, thus making it an ideal candidate for use in this setting. This study aimed to evaluate the reliability of thrice-weekly parenteral temocillin in haemodialysis patients by characterising the pharmacokinetics of total and free temocillin. Free and total temocillin concentrations were determined with a validated HPLC method in 448 samples derived from 48 administration cycles in 16 patients with ESRD treated with intermittent haemodialysis and temocillin. Pharmacokinetics were non-linear partly due to saturation in protein binding. Median clearance and half-life for the free drug during intradialysis and interdialysis periods were 113 mL/min vs. 26 mL/min and 3.6 h vs. 24 h, respectively, with dialysis extracting approximately one-half of the residual concentration. The free temocillin concentration remained >16 mg/L (MIC90 threshold for most Enterobacteriaceae) during 48%, 67% and 71% of the dosing interval for patients receiving 1 g q24h, 2 g q48h and 3 g q72h, respectively, suggesting appropriate exposure for the two latter therapeutic schemes. Temocillin administered on dialysis days only in a dosing schedule of 2 g q48h and 3 g q72h is appropriate for the treatment of serious and/or resistant Gram-negative infections in patients with ESRD undergoing intermittent haemodialysis. These doses are higher than those previously recommended. Copyright © 2015 Elsevier B.V. and the International Society of Chemotherapy. All rights reserved.

    To evaluate and compare the quality of life and oral health indicators in patients undergoing haemodialysis considering the influence treatment duration. One hundred patients were divided into two groups according to the duration of haemodialysis: (1) quality of life domains of psychological (p = 0.003), social relationships (p ≤ 0.001) and environment (p = 0.013) as well as in total quality of life (p = 0.001) and general health (p = 0.010). Similarly, evaluation of the Simplified Oral Hygiene Index and the Decayed, Missing, Filled Teeth index demonstrated worse oral health for group 2 (p = 0.029; p = 0.012, respectively). For both groups, there was a negative correlation between these oral health indicators and psychological and social relationships domains, as well as with the total quality of life score. This study showed that poor oral health indicators may be a reflection of an unsatisfactory overall quality of life in patients undergoing haemodialysis for a prolonged period of time.

    Full Text Available Chronic kidney disease is growing and the current estimated global prevalence exceeds 13%. As the use of haemodialysis machines for patients with end stage renal disease increases survival considerably, it is critical to plan correctly for the allocation of these machines. This study aimed to develop a geographical information systems (GIS-based approach to predict the need for this service in the northeastern region of Iran taking into account where patients live and where haemodialysis is the most needed and identifying areas with poor access to haemodialysis centres. Patients were interviewed to obtain self-reported actual travel time and the inverse distance-weighting algorithm was used to determine access in each area. The prediction is based on the domestic growth rate for haemodialysis services and the estimated active hours of machine use for the next five years. We estimate that six new haemodialysis machines are required in northeastern Iran at the present time with 50 machines required over the next five years. Ashkhane City was identified to have the least access to haemodialysis centres in the study area. Our GIS-based model can be used to investigate not only the need for new haemodialysis machines but also to examine geographic disparities in the allocation of haemodialysis centres and to identify areas most in need of this service. It is important that policymakers consider both spatial and non-spatial dimensions of access to enable better allocation of haemodialysis services ensuring they are targeted to reach those in need.

    Determining aluminium concentrations in the serum of patients undergoing chronic renal replacement therapy with haemodialysis and concentration in distribution network water and dialysis in two renal units in Bogotá. This was a descriptive study of 63 haemodialysed patients and 20 healthy subjects. Aluminium concentration was determined in water and serum using graphite furnace atomic absorption spectrometry with deuterium lamp background corrector. Average aluminium concentration was 26.5 µg/L in patients (ranging from 11.2 to 49.2 µg/L; 8.03 standard deviation) and 8.05 µg/L in healthy individuals (ranging from undetectable to 17.2 µg/L; 4.31 standard deviation). Aluminium concentration in dialysis water and distribution network water was below 2 µg/L and 200 µg/L, respectively. Aluminium concentration in water and serum in this study was below international standard values, thereby indicating appropriate treatment. Additionally, aluminium concentration in pre-HD and post-HD sera was below that reported previously. Aluminium hydroxide uptake increases aluminium concentration in serum. Personal situation regarding age, gender, civil and work status were not risk factors determining aluminium concentrations in serum.

    Fluid management in haemodialysis (HD) affects patient experience, morbidity and mortality. Standards for best practice are lacking. A national survey of the United Kingdom was undertaken to define prevalent practice. An online questionnaire was distributed to all UK renal centres. Forty-five of 74 centres (173 dialysis units), serving 62% (n = 14,697) of UK HD population responded. Seventy-eight per cent had no agreed policy for managing fluid balance in patients on HD; 44% did not assess fluid status routinely. Clinical assessment was the norm; 27% used bio-impedance-based device. To achieve a target-weight, 53% reduced weight as far as tolerated. Twenty-two per cent measured residual renal function (RRF). Ninety-one per cent had no policy for fluid overload. Sixty-four per cent restricted salt and water. Ninety-three per cent used diuretics in patients with RRF. Thirty-eight per cent felt management was adequate; 77% felt there was a need for better evidence. Ninety-one per cent would participate in a study addressing this. There is an urgent need for establishing an evidence base on the optimal approaches to fluid management. © 2016 S. Karger AG, Basel.

    Malnutrition is closely related to inflammation and atherosclerosis in uraemic patients. There is still debate on how to quantify nutritional status in order to achieve the best prediction of mortality and hospitalization. Different methods to detect malnutrition were prospectively investigated for their prognostic impact on mortality and hospitalization of haemodialysis (HD) patients. We compared clinical nutrition scores (body mass index, BMI; subjective global assessment, SGA; malnutrition inflammation score, MIS; and nutritional risk screening, NRS) to lab parameters of protein and lipid metabolism, or bioelectrical impedance analysis (BIA) in 90 HD patients. Over a 3-year follow-up, all-cause mortality and hospitalization were evaluated using a Cox regression model. The scores SGA, NRS, MIS, serum albumin, prealbumin, transferrin and BIA were predictive of both mortality and hospitalization. Elevated CRP predicted only a significantly higher mortality. After adjustment for age, gender, dialysis vintage and diabetes status, the best prognostic parameters for mortality were the clinical nutrition scores, MIS-Index > or = 10 [HR 6.25 (2.82-13.87), P clinical nutrition scores are superior compared to lab markers and BIA. To confirm malnutrition, we propose using clinical nutrition score generally or at least in the case of two malnutrition-positive parameters (lab, BIA, BMI).

    Little is known about whether the arteriovenous type haemodialysis access affects cardiac function and whether it is still advantageous to the uremic patient with symptomatic heart disease. We conducted a retrospective comparative study. Patients with heart disease and end-stage renal disease that had a new chronic access created between January 2007 and December 2008 and met the inclusion criteria were assessed. The endpoint was major adverse event (MAE)-free survivals of arteriovenous access (AVA) and tunneled cuffed double-lumen central venous catheter (CVC) groups. Whether accesses worsened heart failure was also evaluated. There were 43 CVC patients and 60 AVA patients. The median follow-up time from access creation was 27.6 months (IQR 34.7, 10.9~45.6). Although CVC patients were older than AVA patients (median age 78.0, IQR 14.0 vs. 67.5, IQR 16.0, respectively, p = .009), they manifested non-inferior MAE-free survival (mean 17.1, 95% CI 10.3~24.0 vs. 12.9, 95% CI 8.5~17.4 months in CVC and AVA patients, respectively, p = .290). During follow-up, more patients in the AVA group than in the CVC group deteriorated in heart failure status (35 of 57 vs. 10 of 42, respectively, odds ratio 5.1, p heart disease and end stage renal disease (ESRD), CVC patients showed non-inferior MAE-free survival in comparison to those in the AVA group. AV type access could deteriorate heart failure. Accordingly, uremic patients with symptomatic heart disease are not ideal candidates for AV type access creation.

    Scintigraphic localisation of parathyroid glands is often unsuccessful in patients with renal failure on chronic haemodialysis who have secondary hyperparathyroidism (HPT). The purpose of this study was to investigate the use of {sup 11}C-methionine PET/CT to detect hyperfunctioning parathyroid glands in patients with renal failure on chronic haemodialysis who had {sup 99m}Tc-sestamibi-negative HPT. {sup 11}C-methionine PET/CT was performed in 18 patients (11 women and 7 men, aged 42-79 years; mean age 57.8 years) on haemodialysis for renal failure (2-14 years' duration), with normo-, hypo- or hypercalcaemia and HPT not localised by either dual-tracer {sup 99m}Tc-pertechnetate/{sup 99m}Tc-sestamibi subtraction scans or dual-phase {sup 99m}Tc-sestamibi scans. In three of ten patients with normo- or hypocalcaemic HPT there was increased {sup 11}C-methionine accumulation in one gland. Seven of eight patients with hypercalcaemic HPT showed increased uptake: in five of these patients increased {sup 11}C-methionine accumulation was present in one gland, while in two it was demonstrated in two glands. All patients also had high-resolution ultrasound of the neck and were treated with subtotal parathyroidectomy, leaving a remnant of the smallest of the four glands. Regardless of their size, all glands with abnormal {sup 11}C-methionine parathyroid uptake were removed, and all demonstrated parathyroid hyperplasia. All patients developed post-parathyroidectomy hypoparathyroidism and one patient with normocalcaemic HPT relapsed 8 months after surgery. These data suggest that {sup 11}C-methionine PET/CT may be used to identify hyperfunctioning parathyroid glands in non-primary HPT, and especially hypercalcaemic HPT, when conventional {sup 99m}Tc-sestamibi imaging is non-localising.

    Treating depression among patients with chronic kidney disease (CKD) is imperative because of its high prevalence and health-related costs. However, many patients with CKD experience significant barriers to effective face-to-face psychological treatments. Internet-delivered cognitive behaviour therapy (iCBT) may help overcome the treatment barriers. The aim of the present study was to explore the acceptability and preliminary efficacy of iCBT for depression and anxiety among patients with CKD on haemodialysis. A single-group open trial design involving 22 patients on dialysis and an established iCBT treatment for anxiety and depression was employed. The primary outcomes were symptoms of depression, anxiety and general psychological distress. The secondary and tertiary outcomes were disability, quality of life, kidney disease-related loss and kidney disease burden. A generalised estimation equation modelling technique was employed. Clinically significant improvements (avg. % of improvement) were observed in the primary outcomes of depression (34%), anxiety (31%) and general distress (26%), which were maintained or further improved to 3-month follow-up. Improvements were also observed for quality of life (12%) and kidney disease-related loss (30%). However, no improvements in disability and kidney disease burden were found. High levels of acceptability were reported and relatively little clinician time (99.45min; SD=14.61) was needed to provide the treatment. The present results provide encouraging support for the potential of iCBT as an innovative way of increasing access to effective psychological treatment for CKD patients. These results provide much needed support for further research in this area. Australian and New Zealand Clinical Trials Registry: ACTRN12613000103763. Copyright © 2016 Elsevier Inc.

    Full Text Available The IFN-λ3 gene (IFNL3 plays a role in HCV clearance. We investigated circulating IFN-λ3 and IFNL3 SNPs in haemodialysis patients who differed in their response to HBV vaccination and their HBV/HCV infection status. In 201 patients, plasma IFN-λ3 was determined using ELISA. IFNL3 SNPs (rs12979860, rs8099917 were genotyped using HRM analysis. Differences in IFN-λ3 levels were shown between responders and nonresponders to HBV vaccination and between HBsAg-positive patients and those who developed anti-HBs after infection and became HBsAg negative. HBV vaccine responders without HCV resolution revealed lower IFN-λ3 than noninfected responders. HBsAg/HCV RNA-positive subjects showed lower IFN-λ3 than patients positive only for HCV RNA or subjects who resolved both infections. Circulating IFN-λ3 correlated positively with anti-HBs and negatively with positive HCV RNA testing in the adjusted regression analyses. HBV vaccine nonresponders, HBsAg-positive patients, and subjects with replicating HCV composed a group with unfavourable outcomes. Responders to HBV vaccination, subjects who became HBsAg negative, and those who cleared HCV were analysed as having favourable outcomes. The latter showed higher IFN-λ3 but did not differ in distribution of IFNL3 SNPs compared with subjects with unfavourable outcomes. Higher IFN-λ3 concentrations are associated with response to HBV vaccination, self-limited HBV infection, and HCV resolution.

    Parathormone plays a key role in controlling mineral metabolism. PTH is considered a uremic toxin causing cardiovascular damage and cardiovascular mortality in dialysis patients. There are two different assays to measure PTH called 2nd generation or intact PTH (iPTH) and 3rd generation or bioPTH (PTHbio). To evaluate the differences in mortality of dialysis patients between both assays to measure PTH, as well as the possible prognostic role of the PTHbio/iPTH ratio. 145 haemodialysis patients were included with 2-year monitoring including baseline laboratory test and annually thereafter. 21 patients died in the first year and 28 in the second. No correlation was found between PTH, PTHbio and PTHbio/iPTH ratio with mortality. Both PTH have a perfect correlation between them and correlate similarly with other molecules of the mineral metabolism. The extreme baseline values of PTH are those of higher mortality. In survival by iPTH intervals (according to guidelines and COSMOS study), a J curve is observed. When iPTH increases, the ratio decreases, possibly when increasing fragments no. 1-84. There is no greater prognostic approximation on mortality with PTHbio than PTHi. There was also no difference in mortality when progression ratio PTHbio/PTHi was analysed. We didn't find any advantages to using bioPTH vs. PTHi as a marker of mortality. BioPTH limits of normality must be reevaluated because its relationship with iPTH is not consistent. Not knowing these limits affects its prognostic value. Copyright © 2017 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

    This study aimed to evaluate the cost-effectiveness of haemodialysis (HD), continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) for patients with end-stage renal disease (ESRD) in Singapore. A Markov model was developed to examine the incremental cost-effectiveness ratios (ICERs) of HD, CAPD and APD over the 10-year time horizon from the societal perspective, using clinical data from an observational study and the national renal registry, utilities from published studies and costs from dialysis services providers. The base-case analysis was for a hypothetical cohort of 60-year-old non-diabetic ESRD patients. A high-risk group of 60-year-old diabetic ESRD patients was also studied. In the base-case analysis, the quality-adjusted life-years (QALYs) were 3.27 with CAPD, 3.48 with APD and 4.69 with HD. The total costs were Singapore dollar $169 872 for CAPD, $201 509 for APD and $306 827 for HD. CAPD and HD had extended dominance over APD. The ICER of HD versus CAPD was $96 447 (US$69 121) per QALY. One-way sensitivity analyses indicated that the results were most sensitive to the utility of HD. Probabilistic sensitivity analyses demonstrated that CAPD had the maximum probability of being cost-effective among treatments under evaluation at a willingness-to-pay (WTP) threshold of $60 000 (US$43 000) per QALY. The high-risk group analyses showed similar results. The ICER of HD versus CAPD was $106 281 (US$76 168) per QALY and the probability of CAPD being optimal was the highest using the same WTP threshold. Our analysis suggested that starting dialysis with CAPD is most cost-effective for ESRD patients in Singapore. © 2015 Asian Pacific Society of Nephrology.

    Each haemodialysis treatment requires the application of anticoagulation medicines, which will prevent coagulation in extracorporal blood circulation. In this study we try to determine the quality of admitted anticoagulant and his effect on lipid profile on hemodialysis patients after twelve months. We were applying standard heparin and low weight molecular heparin (LWMH). During our study we was analyzed effect of anticoagulant therapy on lipid profile of hemodialysis patients. In that parameters was included triglycerides, cholesterol, lipoprotein fractions, complete blood count, Hgb, HCT; All of these parameters was analyzed in correlation with duration of hemodialysis treatment, sex and age of the patients. Our research was carried out as a prospective study, for the period of 12 months. In the study were included 60 patients (34M/26F), who were on chronic hemodialysis program. All patients were divided into two groups. The first group of patients was included 27 patients (15M/12F) who were treated with standard heparin. The second group was included 33 patients (19M/14F) treated with LWMH (enoxaparin). The average length of hemodialysis was 4.15 +/- 0.52 years. Each patient had a protocol in which is marked parameters such as flushing dialysator, creating fibrin-ring in vein and arterial dropper and the time it takes to stop the bleeding. In the results the average age amounted to 58.54 +/- 2.24 years. The average value of cholesterol in the blood was 5.38 +/- 2.26. Values of HDL-cholesterol in patients treated with LWMH were significantly lower (Pprofile. After the first six months of study in male patients treated with standard heparin in relation to the female part of the observed patients was significantly better anticoagulation effect in the first half of the study (1.85 +/- 0.05 compared to 2.09 +/- 0.10) (Pprofiles. Patients treated with standard heparin had a statistically significant reduction in the rate of blood clots than patients who received

    Patients with the end-stage renal disease often suffer from numerous concomitant diseases. The most common are complications of the cardiovascular system. During the haemodialysis treatment, rapid changes in volume status, osmolality and electrolyte composition of the blood, cause disturbances which manifest as haemodynamic instability, hypotension and cardiac arrhythmias. Especially vulnerable are elderly patients and patients with generalized atherosclerosis, diabetes mellitus, and severe anaemia. Rapid decrease in serum potassium concentration may cause fatal arrhythmias. Contemporary dialysis machines enable slow lowering of potassium concentration during the haemodialysis session (or during the acetate-free biofiltration), what significantly decreases incidence of cardiac arrhythmias and improve cardiovascular stability.

    Different types of mutations in the DMD gene underlie Duchenne muscular dystrophies (DMD) and Becker muscular dystrophies (BMD). Large deletions and duplications are the most frequent causative genetic alterations worldwide, but little is known about DMD/BMD genetic profile in Brazil. Hence, we recruited patients with DMD and BMD from 8 neuromuscular reference centers along the country, and performed a comprehensive molecular investigation that included Multiplex Ligation-dependent Probe Amplification and Next generation sequencing (NGS) analyses. We evaluated 199 patients from 177 unrelated families: 166 with DMD, 32 with BMD and 1 1.5 years old asymptomatic patient with persistent hiperCKemia. Overall, large deletions (58.2%) followed by nonsense mutations (12.4%) and large duplications (11.3%) were the most frequent variants in Brazilian families. Large deletions were less frequent in BMD than in DMD (44.8% vs 60.8%). We identified 19 new DMD variants. Nonsense mutations were significantly more frequent in patients from northeastern region than from southern/southeastern regions of Brazil (27.7% vs 8.5%, P profile of Brazilian patients with DMD/BMD is similar to previously reported cohorts, but it is not uniform across the country. This information is important to plan rational clinical care for patients in face of the new coming mutation-specific therapies. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Increased permeability of the intestinal wall and intestinal dysbiosis may contribute to chronic systemic inflammation, one of the causes of accelerated atherosclerosis and cardiovascular morbidity and mortality burden in patients with chronic kidney disease. The aim of this study was to evaluate the association between markers of intestinal permeability and inflammation in haemodialysis (HD) patients. Plasma concentration of zonulin, haptoglobin, TNFα, IL6, D-lactates and bacterial lipopolysaccharides (LPS) was assessed in blood samples obtained after overnight fast before midweek morning HD session in 150 stable, prevalent HD patients. Daily intake of energy and macronutrients was assessed on the basis of a food frequency questionnaire. Serum hsCRP level was increased in over 70% of patients. Plasma levels of zonulin [11.6 (10.9-12.3) vs 6.8 (5.8-7.8) ng/mL], IL6 [6.2 (1.0-10.3) vs 1.3 (1.0-2.0) pg/mL] and TNFα [5.9 (2.9-11.8) vs 1.6 (1.3-1.8) pg/mL], but not LPS and D-lactates were significantly higher in HD than in healthy controls. D-lactates and LPS levels were weakly associated with IL6 (R = 0.175; p = 0.03, and R = 0.241; p = 0.003). There was a borderline correlation between plasma zonulin and serum hsCRP (R = 0.159; p = 0.07), but not with IL6, LPS and D-lactates. In multiple regression, both serum CRP and plasma IL6 variability were explained by LPS (β = 0.143; p = 0.08 and β = 0.171; p = 0.04, respectively), only. The weak association between plasma D-lactate, LPS and IL6 levels indicates that intestinal flora overgrowth or increased intestinal permeability contributes very slightly to the chronic inflammation development in HD patients.

    Haemodialysis is a form of renal replacement therapy but is a catabolic process that not only filters toxins but is also known to lead to amino acid losses. Patients with chronic kidney disease often have a poor appetite and this in combination with limited dietary intake and the detrimental effects of haemodialysis can lead to the development of malnutrition. Between 20% and 50% of haemodialysis patients are thought to be malnourished. Malnutrition can worsen clinical outcomes and increase the risk of hospitalisation. We hypothesise that a nutritional supplement taken during haemodialysis may help to improve nutritional status. The aim of this study is to conduct a pilot randomised controlled trial to assess the use of an intradialytic nutritional supplement on nutritional status. The objectives are to assess the feasibility of the trial including: recruitment and retention of participants; preference of nutritional supplements; compliance with the intervention; ease of completion of the questionnaires and appropriateness of the tools used. Secondary outcomes include clinical outcomes to obtain variance in the patient population and estimates of effect size to inform the sample size for a future definitive trial. The trial is a single centre, randomised, parallel-group, two armed external pilot with an intervention and control group. The intervention group will take a nutritional supplement each dialysis session from a choice of prescribable drink or pudding style supplements. The control group will receive standard care. Recruitment and feasibility elements are the primary outcomes. Recruitment will be to time (t = 6 weeks). In order to collect sufficient data to inform a future sample size calculation, we will aim to recruit 30 participants to obtain 12 evaluable per arm anticipating some drop out. Secondary outcome measures include clinical variables; hand grip strength, quality of life, weight and biochemistry completed at baseline, 1 and 2 months

    The first government funded and sustainable dialysis unit was established in Ethiopia at Saint Paul's Hospital Millennium Medical College (SPHMMC). This has led to the development of a unique cohort of patients about which very little is known. This study was conducted to describe the clinical profile and outcome of adult Acute Kidney Injury (AKI) patients treated with intermittent haemodialysis at the dialysis center of SPHMMC. A retrospective review of clinical records of cases of AKI who required haemodialysis support during the time period from August 1, 2013 to February 1, 2015 was conducted. A total of 151 cases AKI requiring dialysis were included for the study. Overall, the patients were generally younger with a mean age of 36.7 years and thus with few premorbid conditions. The most common causes of AKI were hypovolemia (22.5 %), acute glomerulonephritis (AGN) (21.9 %) and pregnancy related causes (18.5 %). Nearly a third (29.1 %) of patients succumbed to the AKI. Infections, AGN, obstetric causes and nephrotoxins were the primary causes of dialysis requiring AKI. Most of these causes can be prevented with simple interventions such as health education on oral rehydration, quality prenatal and emergency obstetric care, appropriate management of infections and taking appropriate precautions when prescribing potentially nephrotoxic medications.

    Haemodialysis patients are at risk of serious health complications; yet, treatment non-adherence remains high. Warnings about health risks associated with non-adherence may trigger defensive reactions. We studied whether an intervention based on self-affirmation theory reduced resistance to health-risk information and improved fluid treatment adherence. In a cluster randomised controlled trial, 91 patients either self-affirmed or completed a matched control task before reading about the health-risks associated with inadequate fluid control. Patients' perceptions of the health-risk information, intention and self-efficacy to control fluid were assessed immediately after presentation of health-risk information. Interdialytic weight gain (IDWG), excess fluid removed during haemodialysis, is a clinical measure of fluid treatment adherence. IDWG data were collected up to 12 months post-intervention. Self-affirmed patients had significantly reduced IDWG levels over 12 months. However, contrary to predictions derived from self-affirmation theory, self-affirmed participants and controls did not differ in their evaluation of the health-risk information, intention to control fluid or self-efficacy. A low-cost, high-reach health intervention based on self-affirmation theory was shown to reduce IDWG over a 12-month period, but the mechanism by which this apparent behaviour change occurred is uncertain. Further work is still required to identify mediators of the observed effects.

    Cystathionine beta-synthase (CBS) deficiency is the most common cause of homocystinuria. However, no data are available concerning the molecular basis of this disease in Brazilian populations. We studied 14 Brazilian patients from 11 unrelated families using a combined screening approach, involving restriction analysis, single-strand conformational polymorphism (SSCP) scanning, and sequencing. All patients presented homocysteine levels higher than 200 mumol/l before the beginning of treatment. The most common CBS gene mutations, p.G307S (c.919G > A) and p.I278T (c.833T > C), were evaluated and the allele c.919A was not found. One allele with the c.844 ins68 (4.5%) in the CBS gene was found. Three families (6 patients) presented the allele c.833 C (13.6%), without the insertion in the heterozygous state. SSCP scanning and sequencing showed 3 alleles p.T191M (13.64%) in 2 families. One allele with a novel mutation was found in exon 4 (c.168T > A) of the CBS gene (4.5%). We also analyzed c.677C > T and c.1298A > C polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene and the 2756A > G polymorphism in the methionine synthase (MTR) gene. The frequencies of mutated alleles were: 50% c.677T and 18.2% c.1298C for MTHFR, and 27.3% c.2756G for MTR. In spite of the high level of racial mixing in the country, Brazilian homocystinuric patients did not present a high prevalence of the most common mutations described in the literature.

    Full Text Available End stage renal disease affects two million patients worldwide. Health related quality of life (HRQoL has recently become a major indicator of health and well-being of patients with kidney disease. The present goal for the treatment of patients with ESRD is not simply to prolong life, but also to provide a better HRQoL. This goal can be achieved through patient counseling. A simple prospective study was used to examine the effect of patient counseling on HRQoL of hemodialysis patients. In the study, a Short Form-36 (SF-36 questionnaire and clinical parameters were used for 52 hemodialysis patients to assess the HRQoL before and after patient counseling. All the Patients were kept under observation for a period of three months to study the effect of patient counseling. After three months period of counseling a significant (p<0.05 improvement was observed for hemodialysis patients. Also HRQoL score was higher for hemodialysis patients after counseling. This study concluded that knowledge of the disease and its management through patient counseling could improve the HRQoL of hemodialysis patients.

    Chronic kidney disease causes hyperphosphatemia, which is associated with increased cardiovascular risk and mortality. In patients with end-stage renal disease, haemodialysis allows the control of hyperphosphatemia. During a 4-h haemodialysis session, between 600 and 700mg of phosphate are extracted from the plasma, whereas the latter contains only 90mg of inorganic phosphate. The precise origin of phosphates remains unknown. The modelling of phosphorus transfers allows to predict the outcome after changes in dialysis prescription (duration, frequency) with simple two-compartment models and to describe the transfers between the different body compartments with more complex models. Work using 31P nuclear magnetic resonance spectroscopy performed in animals showed an increase in intracellular phosphate concentration and a decrease in intracellular ATP during a haemodialysis session suggesting an intracellular origin of phosphates.

    Despite the paucity of scientific evidence, complementary and alternative medicine (CAM) is widely used for the prevention and treatment of illness, holistic care, and counteracting the adverse effects of conventional medicine (CM). This study investigates the use of CAM by patients with end-stage renal disease (ESRD) on haemodialysis. This quantitative study was conducted from November 1, 2014 to December 31, 2014 in the haemodialysis unit at San Fernando General Hospital (San Fernando, Trinidad). Face-to-face questionnaire-based interviews were held with101of 125 eligible patients (response rate, 80.5%) at the chairside during haemodialysis. The completed questionnaires were entered into a secure computer database. Data analysis included descriptive analysis, χ2 tests, and binary logistic regression analysis. A minority of the patients were CAM users (n = 19; 18.8%). All 19 CAM users took medicinal herbs, 78.9% (n = 15) used spiritual therapy, and 10.5% (n = 2) used alternative systems. Medicinal tea (n = 15; 78.9%), garlic (Allium sativum) (n = 17; 73.7%), and ginger (Zingiber officinale roscoe) (n = 13; 68.4%) were the most commonly used medicinal herbs. Seven (36.8%) patients used Chinese herbal medicines and 3 (15.8%) patients used Aloe vera. All CAM users were willing to use CAM without supervision or monitoring by their doctors while receiving CM. The use of CAM could not be predicted by age, sex, ethnicity, education, religion, marital status, or employment. Nearly all (98%) patients were satisfied with CAM. More than one-third (36.8%) of patients did not disclose their use of CAM to their doctors, who were generally indifferent to such therapy. The use of CAM by patients with ESRD was relatively infrequent. All patients used medicinal herbs, most patients used spiritual therapy, and a minority of patients used alternative systems. Complementary and alternative medicine was primarily used for spiritual reasons and the likelihood of its use was

    To study the outcome of radiologically placed double lumen tunneled haemodialysis catheters for the management of renal failure. Case series. Interventional Suite of Radiology Department at the Aga Khan University Hospital, Karachi, from April 2010 to June 2011. All consecutive patients who were referred to the department of radiology by the nephrologists for double lumen tunneled haemodialysis catheter (Permacath) placement during the study period were included. Patients with septicemia, those for whom follow-up was not available, those coming for catheter exchange or who died due to a noncatheter related condition were excluded. A radio-opaque, soft silicone double lumen catheter was inserted through a subcutaneous tunnel created over the anterior chest wall. The catheter tip was placed in the right atrium via the internal jugular vein. Ultrasound guidance was used for initial venous puncture. The rest of the procedure was carried out under fluoroscopic guidance. Technical success, catheter related bacteremia rates, adequacy of dialysis, patency, and adverse events were analyzed. Overall 88 tunneled haemodialysis catheters were placed in 87 patients. Patients were followed-up for duration of 1 - 307 days with mean follow-up period of 4 months. Immediate technical success was 100%. The procedural complication rate was 5.6% (5 catheters). Eight patients died during the study period, seven from causes unrelated to the procedure. One patient died due to septicemia secondary to catheter related infection. Of the remaining 69 patients, 50 (72.4%) predominantly had uneventful course during the study period. Twelve patients developed infection (17.3%); two were successfully treated conservatively while in 10 patients catheter had to be removed. Seven catheters (10.1%) failed due to mechanical problems. In 3 patients the internal jugular veins got partially thrombosed. One catheter was accidentally damaged in the ward and had to be removed. Radiological guided tunneled

    Full Text Available Abstract In rare cases (1-8% diabetic patients with end-stage renal disease (ESRD suffer from diabetic nephropathy (dNP due to pancreatic diabetes mellitus (PDM. Aim of this study was to investigate differences in the outcome of patients with PDM and those with type 2 diabetes. In a retrospective study we evaluated 96 diabetic patients, who started hemodialysis (HD in our dialysis centre (1997-2005. In 12 patients PMD was diagnosed, and 84 patients had type 2 diabetes. In both groups we compared vascular risk factors and prevalence of vascular diseases at the start of dialysis. We also evaluated incidence of malnutrition, and 5-year survival in both patient groups. The vascular risk factors were similar in both patient groups, also the prevalence of vascular diseases at the initiation of HD was similar in both groups. In the patients with PDM the mean BMI (kg/m2 was lower (22 + 3 versus 25 + 3, and also their serum albumin was lower (2.7 + 0.3 versus 3.4 + 0.3 g/dl, p Conclusions in HD-treated patients with type 2 diabetes or PDM the prevalence of vascular diseases was not significantly different. The lower survival of PDM patients can be related to poor nutrition status.

    Results and discussion: Age at diagnosis was between 10 and 32 months and the severity of the disease correlated with the increasing of age at diagnosis. The predominant symptoms were vomiting, weight loss, and hepatomegaly. Severe renal tubular acidosis manifested in one child. All patients had remission of symptoms after dietary modification. The sequencing of the ALDOB gene identified one homozygous patient for the mutation c.524C>A (p.A175D, while the others were compound heterozygous for c.360_363delCAAA (p.N120KfsX32, c.178C>T (p.R60X mutations, c.448G>C (p.A150P and c.524C>A (p.A175D. Clinical improvement of patients after dietary treatment is suggestive of the diagnosis, confirmed by molecular analysis. The prevalence of mutations found in our Brazilian patients is different from those of international literature.

    Full Text Available Background: Haemodialysis (HD patients are a high-risk population group. For these patients, an error could have catastrophic consequences. Therefore, system that ensures the safety of these patients in an environment with high technology and great interaction of the human factor is a requirement. Objectives: To show a systematic working approach, reproducible in any HD unit, which consists of recording the complications and errors that occurred during the HD session; defining which of those complications could be considered adverse event (AE, and therefore preventable; and carrying out a systematic analysis of them, as well as of underlying real or potential errors, evaluating their severity, frequency and detection; as well as establishing priorities for action (Failure Mode and Effects Analysis system [FMEA systems]. Methods: Retrospective analysis of the graphs of all HD sessions performed during one month (October 2015 on 97 patients, analysing all recorded complications. The consideration of these complications as AEs was based on a consensus among 13 health professionals and 2 patients. The severity, frequency and detection of each AE were evaluated by the FMEA system. Results: We analysed 1303 HD treatments in 97 patients. A total of 383 complications (1 every 3.4 HD treatments were recorded. Approximately 87.9% of them were deemed AEs and 23.7% complications related with patients’ underlying pathology. There was one AE every 3.8 HD treatments. Hypertension and hypotension were the most frequent AEs (42.7 and 27.5% of all AEs recorded, respectively. Vascular-access related AEs were one every 68.5 HD treatments. A total of 21 errors (1 every 62 HD treatments, mainly related to the HD technique and to the administration of prescribed medication, were registered. The highest risk priority number, according to the FMEA, corresponded to errors related to patient body weight; dysfunction/rupture of the catheter; and needle extravasation

    2017-01-01

    Full Text Available There is accumulating evidence that the intestinal barrier and the microbiota may play a role in the systemic inflammation present in HD patients. HD patients are subject to a number of unique factors, some related to the HD process and others simply to the uraemic milieu but with common characteristic that they can both alter the intestinal barrier and the microbiota. This review is intended to provide an overview of the current methods for measuring such changes in HD patients, the mechanisms behind these changes, and potential strategies that may mitigate these modifications. Lastly, intradialytic exercise is an increasingly employed intervention in HD patients; however the potential implications that this may have for the intestinal barrier are not known; therefore future research directions are also covered.

    Simulation is a well-established and proven teaching method, yet its use in renal education is not widely reported. Criticisms of simulation-based teaching include limited realism and a lack of authentic patient interaction. This paper discusses the benefits and challenges of high-fidelity simulation and suggests hybrid simulation as a complementary model to existing simulation programmes. Through the use of a simulated patient, hybrid simulation can improve the authenticity of renal simulation-based education while simultaneously teaching and assessing technologically enframed caring. © 2015 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    To prospectively investigate and detect early cerebral metabolic changes in patients with end-stage renal disease (ESRD) by using in vivo proton MR spectroscopy (MRS). We enrolled 32 patients with ESRD and 32 healthy controls between the ages of 26 and 50 years. Short echo time single-voxel proton MRS was acquired from volumes of interest (VOIs) located in the frontal grey and white matter, temporal white matter and basal ganglia. The choline/phospatidylcholine (Cho), myo-inositol (mI), N-acetylaspartate (NAA) and total creatine (tCr) peaks were measured and the metabolic ratios with respect to tCr were calculated. In the ESRD group, significant elevations of the Cho/tCr and mI/tCr ratios were observed for the frontal grey matter, frontal white matter, temporal white matter and basal ganglia as compared with controls. There was no significant difference in the NAA/tCr ratios at all VOIs between the ESRD patients and the healthy controls. Proton MRS is a useful and non-invasive imaging tool for the detection of early cerebral metabolic changes in neurologically presymptomatic ESRD patients. (orig.)

    Plasma anti-Xa activity, the recommended test to monitor low-molecular weight heparin (LMWH) therapy, is not readily available in many laboratories. In our clinical trials on the use of LMWH as anticoagulation for haemodialysis, a consistent prolongation of APTT in addition to the elevated anti-Xa activity was observed in the patients after LMWH administration. Hence, the paired anti-Xa activity and APTT data were re-analyzed. The APTT ratio, which was the proportional change in APTT from the baseline value after LMWH administration, was found to have a strong correlation with anti-Xa activity (coefficient of determination, R 2  = 0.72, P sensitivity was 88% and the specificity was 83.3% when an APTT ratio ≧1.4 was used as the cut point to predict the achievement of therapeutic anti-Xa activity. Our results illustrated that APTT is a potentially useful screening test to assess the degree of anticoagulation achieved by LMWH during haemodialysis, if the testing for plasma anti-Xa activity is not available. © 2017 Asian Pacific Society of Nephrology.

    Ongoing discussion on anaemia management and target haemoglobin (Hb) levels in patients on haemodialysis with erythropoietin treatment require a systematic approach in evaluating current practice. Aim of the present study was to develop a new classification system to easily monitor Hb trajectories and categorise patients on haemodialysis. Routine data from five dialysis centres in the USA collected between 2010 and 2016. Data were anonymised and only those from patients with fortnightly Hb values were included in the analysis. Entries on blood parameters and medication were standardised to achieve overall comparability. Data from each patient was grouped in periods of 120 days. Hb values above or below the target level of 10-12 g/dL were counted for each period. Periods were then assigned to Hb-classes according to the number of Hb values out of range per period: Hb-class I with 0-2, Hb-class II for 3-5 and Hb-class III for ≥6 values out of range. Records from 3349 patients with fortnightly Hb values, information on haemodialysis data, laboratory parameters correlated to red blood cells and data on medication with erythropoiesis-stimulating agents (ESAs) were available. Patients were 64.4±15.9 years old; 55.0% were men. Statistical analysis revealed significant differences between Hb-classes in all of the examined parameters, except erythrocytes mean corpuscular volume and C reactive protein above the threshold, with more critical values in higher Hb-classes. The usage of ESAs showed a mean difference between Hb-class III and Hb-class I of 6.4 units/day and kilogram body weight in a 120-day period. Our classification system allows an easily achievable overview of the patients' responsiveness and performance of Hb management. Integrated into a disease management programme or continuous quality improvement, the classification delivers an instant appraisal without complex statistical or mathematical processing. © Article author(s) (or their employer(s) unless

    High lipoprotein(a) [Lp(a)] concentrations and low molecular weight (LMW) apolipoprotein(a) [apo(a)] isoforms are associated with cardiovascular disease and mortality in the general population. We examined the association of both with all-cause mortality and cardiovascular endpoints in haemodialysis patients with diabetes mellitus. This is a post hoc analysis of the prospective 4D Study (German Diabetes Dialysis Study) that evaluated atorvastatin compared with placebo in 1255 haemodialysis patients with type 2 diabetes mellitus (median follow-up 4 years). The association of natural logarithm-transformed Lp(a) concentrations (increment one unit) and apo(a) isoforms with outcomes was analysed by Cox proportional hazards regression. The influence of age (median 66 years) was evaluated by stratified survival analyses. The median baseline Lp(a) concentration was 11.5 mg/dL (IQR 5.0-41.8). A quarter of patients had at least one LMW apo(a) isoform. Increased Lp(a) concentrations were associated with all-cause mortality in the total group [hazard ratio (HR) 1.09 (95% CI 1.03-1.16), P = 0.004]. LMW apo(a) isoforms were only associated with all-cause mortality in patients ≤ 66 years [HR 1.38 (95% CI 1.05-1.80), P = 0.02]. The strongest association for Lp(a) concentrations and LMW apo(a) isoforms was found for death due to infection in patients ≤ 66 years [HR 1.39 (95% CI 1.14-1.71), P = 0.001; HR 2.17 (95% CI 1.26-3.75), P = 0.005]. Lp(a) concentrations were also associated with fatal stroke in patients ≤66 years of age [HR 1.54 (95% CI 1.05-2.24), P = 0.03]. Neither Lp(a) nor LMW apo(a) isoforms were associated with other atherosclerosis-related events. High Lp(a) concentrations and LMW apo(a) isoforms are risk predictors for all-cause mortality and death due to infection in haemodialysis patients with diabetes mellitus. These associations are modified by age. © The Author 2016. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

    Full Text Available BRCA1 mutations are known to be responsible for the majority of hereditary breast and ovarian cancers in women with early onset and a family history of the disease. In this paper we present a mutational survey conducted in 47 Brazilian patients with breast/ovarian cancer, selected based on age at diagnosis, family history, tumor laterality, and presence of breast cancer in male patients. All 22 coding exons and intron-exon junctions were sequenced. Constitutional mutations were found in seven families, consisting of one insertion (insC5382 in exon 20 (four patients, one four base-pair deletion (3450-3453delCAAG in exon 11 resulting in a premature stop codon (one patient, one transition (IVS17+2T> C in intron 17 affecting a mRNA splicing site (one patient, and a C> T transition resulting in a stop-codon (Q1135X in exon 11 (one patient. The identification of these mutations which are associated to hereditary breast and ovarian cancers will contribute to the characterization of the mutational spectrum of BRCA1 and to the improvement of genetic counseling for familial breast/ovarian cancer patients in Brazil.

    Anaemia is an important issue in patients undergoing haemodialysis. We aimed to identify a better dosing schedule of a fixed monthly dose of continuous erythropoietin receptor activator (CERA) in patients with chronic kidney disease (CKD) on haemodialysis. The CERA dosing schedule included 100 μg once monthly for 2 months, 50 μg twice monthly for 2 months and then 100 μg once monthly for two months. The effectiveness was determined by comparing haematocrit, nutritional status (serum protein and albumin) and inflammatory markers (tumour necrosis factor (TNF)-α, interleukin (IL)-1, IL-6 and Hepcidin) at the beginning of the study with those at the end of the study. Forty-seven out of 67 patients completed the trial. At the end, haematocrit was significantly higher (34.51 vs 33.22%, P=.004), levels of inflammatory markers were significantly lower (TNF-α (30.71 vs 35.67 ng/mL, P=.007), IL-6 (5.12 vs 7.95 ng/mL, P=.033), hepcidin (60.39 vs 74.39 ng/mL, P=.002)), blood glucose levels were significantly lower (112.40 vs 139.02 mg/dL, P=.003) and albumin was significantly higher (4.11 vs 3.98, P=.001). Patients with a better than average response had a lower initial number of red blood cells (3.3 vs 3.6 × 10(6) /mm(3) , P=.025) and a lower IL-1 (3.8 vs 12.9 ng/mL, P=.01). They also had significantly lower blood glucose levels at the end. (91.3 vs 124.0 mg/dL, P=.03). We demonstrate that a fixed monthly dose of CERA at a twice monthly dosing schedule improves nutrition, reduces the inflammation and corrects anaemia in patients on haemodialysis. This finding may provide a new strategy for treating CKD-related anaemia. © 2016 John Wiley & Sons Australia, Ltd.

    To examine the relationships among nurse and work characteristics, job satisfaction, stress, burnout and the work environment of haemodialysis nurses. Haemodialysis nursing is characterised by frequent and intense contact with patients in a complex and intense environment. A cross-sectional online survey of 417 haemodialysis nurses that included nurse and work characteristics, the Brisbane Practice Environment Measure, Index of Work Satisfaction, Nursing Stress Scale and the Maslach Burnout Inventory. Haemodialysis nurses reported an acceptable level of job satisfaction and perceived their work environment positively, although high levels of burnout were found. Nurses who were older and had worked in haemodialysis the longest had higher satisfaction levels, experienced less stress and lower levels of burnout than younger nurses. The in-centre type of haemodialysis unit had greater levels of stress and burnout than home training units. Greater satisfaction with the work environment was strongly correlated with job satisfaction, lower job stress and emotional exhaustion. Haemodialysis nurses experienced high levels of burnout even though their work environment was favourable and they had acceptable levels of job satisfaction. Targeted strategies are required to retain and avoid burnout in younger and less experienced nurses in this highly specialised field of nursing. © 2013 John Wiley & Sons Ltd.

    The aim of the study was the assessment of dietary habits in haemodialysed women and men with differentiated state of nutrition. The study was conducted into 74 haemodialysed patients who, based on BMI (kg/m2), were allocated into two research groups of women: normal-weight group n =17 (48.6%) and excessive body weight group n = 18 (51.4%) and two groups of men: normal-weight group n = 17 (43.6%) and excessive body weight group n = 22 (56.4%). Daily food rations (DFR) were quantitatively evaluated by a 24h dietary recall method covering 3 days preceding the examination. The computer program "Diet 4" designed in the Institute of Food and Nutrition in Warsaw was used for calculations. Calculations were performed using the Statistica 9.0 program. Results were compared to the nutritional standards for haemodialysed subjects. Energetic value and basic nutrients supply was estimated and also the average content of dietary fiber and cholesterol. The results of the conducted research indicate lack of balanced content of essential nutrients in daily food rations of the patients of both sexes, irrespective of nutritional status. The diet was characterized by low energetic value and low contents of proteins and carbohydrates in all the study groups of women. The mean intake of protein (89.4 +/- 40.6 g/day) and cholesterol (343.9 +/- 207.4 mg/day) in the daily food rations of men with normal weight were found to have a significantly higher as compared to the mean intake of protein (71.9 +/- 25.2 g/day) and cholesterol (253.4 +/- 142.5 mg/day) in the daily food rations of hemodialysed men with excessive body weight. The research showed low consumption of dietary fiber in all investigated groups of women and men. Since improper the energetic value of daily food rations and intake of the basic nutrients in the diets, may have an unfavourable effect on the disease course, the provision of regular dietary advice is a necessity.

    Vascular calcification is a common finding in patients (pts) with end-stage renal disease (ESRD). The aim of this cross-sectional study was to investigate the prevalence and functional effect of native arteriovenous fistula AVF (feeding artery and/or arterialized vein) calcifications evaluated by spiral computed tomography (CT) in ESRD pts undergoing chronic hemodialysis (HD). Forty-five upper limb AVF (radial 44.4% or brachial 55.6%, mean duration 65.3 +/- 80.9 months) without evidence of significant stenosis were evaluated by CT in 45 ESRD pts (mean age 63.8 +/- 13.1 yr; sex M: 71.1%, F: 28.9%; mean time on HD 53.1 +/- 51.9 months; diabetic nephropathy 15.6%). All AVF explorations were performed using the same multi-slice spiral CT scanner (HiSpeed Dual machine, GE Medical Systems). The severity of AVF calcifications was quantified by CT using the following criteria: grade I absence of calcifications, grade II isolated calcifications (20 groups of calcification). Laboratory parameters analyzed: calcium, phosphorus, parathyroid hormone; calcium x phosphorus product was calculated. The same week of CT scanning, we evaluated AVF function measuring the blood flow rate (QA). We determined QA (1559.3 +/- 980.6 ml/min) by the Delta-H method (ABF-mode, HemaMetrics, USA) using the Crit-Line III monitor (68.9%) or by Doppler ultrasound (31.1%) performed by the same radiologist using a 5-8 MHz linear transducer (Sequoia machine, Siemens-Acuson); mean arterial pressure MAP (94.7 +/- 16.3 mmHg) was recorded simultaneous with QA. Most pts not showed AVF calcification by CT scan (grade I: 27/45, 60%). Forty percent of pts (18/45) demonstrated any degree of AVF calcification (grade II 13.3%, grade III 8.9%, grade IV 17.8%). Pts with brachial AVF showed higher mean QA compared to pts with radial AVF (1899.1 +/- 1131.8 versus 1134.5 +/- 516.4 ml/min, p=0.005), but MAP (91.2 +/- 15.8 versus 99.0 +/- 16.2 mmHg) and the prevalence of AVF calcification (32% versus 50%) were not

    Full Text Available Objective. To determine the significance of high serum ferritin observed in Indigenous Australian patients on maintenance haemodialysis in the Northern Territory, we assessed the relationship between ferritin and transferrin saturation (TSAT as measures of iron status and ferritin and C-reactive protein (CRP as markers of inflammation. Methods. We performed a retrospective cohort analysis of data from adult patients (≥18 years on maintenance haemodialysis (>3 months from 2004 to 2011. Results. There were 1568 patients. The mean age was 53.9 (11.9 years. 1244 (79.3% were Indigenous. 44.2% (n=693 were male. Indigenous patients were younger (mean age [52.3 (11.1 versus 57.4 (15.2, p<0.001] and had higher CRP [14.7 mg/l (7–35 versus 5.9 mg/l (1.9–17.5, p<0.001], higher median serum ferritin [1069 µg/l (668–1522 versus 794.9 µg/l (558.5–1252.0, p<0.001], but similar transferrin saturation [26% (19–37 versus 28% (20–38, p=0.516]. We observed a small positive correlation between ferritin and TSAT (r2=0.11, p<0.001, no correlation between ferritin and CRP (r2 = 0.001, p<0.001, and positive association between high serum ferritin and TSAT (p<0.001, Indigenous ethnicity (p<0.001, urea reduction ratio (p=0.001, and gender (p<0.001 after adjustment in mixed regression analysis. Conclusion. Serum ferritin and TSAT may inadequately reflect iron status in this population. The high ferritin was poorly explained by inflammation.

    Aggression on haemodialysis units is a growing problem internationally that has received little research attention to date. Aggressive behaviour by patients or their relatives can compromise the safety and well-being of staff and other patients sharing a haemodialysis session. The objectives of the study were twofold: First, to identify the prevalance and nature of aggression on haemodialysis units; and second, to investigate factors that contribute to aggressive behaviour on haemodialysis units. A cross-sectional, sequential mixed method research design was adopted, with two research methods utilised. Incidents of aggressive behaviour were recorded over a 12-month period, using a renal version of the Staff Observation Aggression Scale. Six months after the incident data collection had commenced, semi-structured qualitative interviews were conducted with 29 multidisciplinary members of staff. Over 12 months, 74 aggressive incidents were recorded. The majority of incidents involved verbal aggression, and the perpetrators were a minority of patients, relatives and staff. Two patients were responsible for 38% of all incidents; both patients had mental health problems. Distinct temporal patterns to the aggressive behaviour were observed according to the day of the week and time of day. This study demonstrates that aggression is a significant problem on haemodialysis units, with verbal aggression most prevalent. The temporal patterns to aggression observed are related to the uniqueness of the haemodialysis setting, with a distinctly different treatment environment compared with other healthcare settings. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Previous studies to determine the cost of haemodialysis (HD) in Spain have significant limitations: they are outdated or used indirect methods. There is also a lack of analysis performed simultaneously on Public centres (PC), with direct HD services, and partially state-subsidised centres (SC). This is an important issue since the two systems coexist in Spain. To estimate the cost of HD replacement therapy for chronic renal failure in several centres. This is a prospective and publicly-funded study, which estimates the costs for 2008 using a cost accounting system with specific allocation criteria. We collected demographic and comorbidity data for each centre. Six centres participated, two PC and four SC. There were no significant differences between centres in terms of patient demographics, time on haemodialysis and the Charlson comorbidity index. The total cost per patient per year ranged between € 46, 254 and € 33,130. The cost per patient per year (excluding vascular access and hospital admission) for PC was € 42, 547 and € 39, 289 and for SC € 32 872, € 29, 786, € 35, 461 and € 35, 294 (23% more in PC than SC). Costs related to staff/patient/year and consumables/patient/year were 67% and 83% respectively, higher for PC than SC. The highest percentage cost was for staff (average 30.9%), which showed significant variability between centres, both in absolute numbers (staff cost per patient per year between € 18,151 and € 8504) and as a percentage (between 42.6 % and 25.4%). Cost variability exists among different HD centres, and this can be attributed primarily to staff and consumables costs, which is higher for PC than SC.

    Full Text Available Acute metabolic decompensation in maple syrup urine disease can occur during intercurrent illness and is a medical emergency. A handful of reports in the medical literature describe the use of peritoneal dialysis and haemodialysis as therapeutic inventions. We report the only patient from our centre to have haemodialysis performed in this setting. Combined with dietary BCAA restriction and calorific support, haemodialysis allows rapid reduction in plasma leucine concentrations considerably faster than conservative methods.

    Patients on renal replacement therapy experience higher rates of morbidity and mortality, infection being the second commonest cause of death. In our haemodialysis population, we identify the pathogens, sensitivity patterns, sources of infection and outcomes of Gram-negative bacteraemia. Data from the NHS Greater Glasgow & Clyde and NHS Forth Valley haemodialysis population were collected July 2011 to April 2014 through an interrogation of the renal unit electronic patient record, and confirmed by an independent search of the Microbiology database. Over 544 377 haemodialysis days, 84 patients experienced 95 Gram-negative bacteraemia events, a rate of 0.175 events per 1000 haemodialysis days, which varied with dialysis modality: non-tunnelled central venous catheters 4.77, arteriovenous grafts 0.24, tunnelled central venous catheters 0.21, and arteriovenous fistulae 0.11 per 1000 haemodialysis days. The commonest sources of bacteraemia were central venous catheters (CVCs) (16.8%, n = 16), infected ulcers (14.7%, n = 14), urinary (10.5%, n = 10), biliary (9.5%, n = 9) and intra-abdominal (9.5%, n = 9).The principal organisms were Escherichia coli (49.5%, n = 47), Enterobacter spp. (13.1%, n = 13), Klebsiella spp. (11.1%, n = 11), Proteus mirabilis (6.1%, n = 6) and Pseudomonas aeruginosa (5.1%, n = 5). Of the Enterobacteriaceae (n = 84), 88% were sensitive to gentamicin, 81% to ciprofloxacin, 91% to piperacillin-tazobactam and 100% were sensitive to meropenem.Three-month case mortality was 25.3% (n = 24). Ten patients (11.9%) had more than one Gram-negative bacteraemia; of these, nine patients (90.0%) were the same causative organism, predominantly E. coli. CVCs and diabetic foot ulcers remain significant risk factors for Gram-negative bacteraemia, highlighting the importance of vascular access planning. Despite good levels of antibiotic sensitivity, the early mortality following Gram-negative bacteraemia remains high, supporting aggressive treatment of such

    To characterize the prevalence and impact of symptoms of scleroderma in Brazilian patients and to describe their satisfaction with medical care and psychological symptoms. One-hundred and twenty eight Brazilian scleroderma patients participated in an online survey by filling out a Portuguese version of the Canadian Scleroderma Patient Survey of Health Concerns and Research Priorities. The mean age of participants was 38 years old (SD = 12.33), and most of the participants were females (n = 108, 88%). Hardening/tightening of skin, itchy skin and joint pain were symptoms reported as being most frequent, whereas muscle pain and difficulty climbing stairs were symptoms reported as having a higher impact. Participants reported dissatisfaction regarding the medical care. Psychological evaluations suggested that participants who scored above clinical values for depression was significantly high (90%; n = 77). In addition, 48% (n = 42) of participants fit the clinical criteria for anxiety disorder, and 40% (n = 35) of participants fit the clinical criteria of social phobia. Finally, body image disturbance was reported by 69% (n = 88) of participants. The physical and psychological symptoms associated with scleroderma have a significant impact on patient quality of life. The Brazilian patients in the current sample report higher levels of dissatisfaction with medical care than patients from Canada and European countries. These Brazilian patients also report more psychopathology, particularly symptoms of depression. The current results suggest that there is a need for professionals to consider and attend to the individual problems of scleroderma patients.

    Waste products of metabolism are retained in haemodialysis (HD) patients. Cellular metabolism generates energy, and patients with greater energy expenditure may therefore require more dialysis. To determine the amount of dialysis required, equations estimating resting and total energy expenditure (REE,TEE) are required. We compared estimates of REE in HD patients using established equations with a novel equation recently validated in HD patients (HD equation). TEE was derived from REE (HD equation) and estimates of physical activity obtained by questionnaire. REE and TEE relationships with bioimpedance measured body composition were then determined. We studied 317 HD patients; 195 males (61.5%), 123 diabetic (38.9%), mean age 65.0 ± 15.3 and weight 73.1 ± 16.8 kg. REE from HD Equation was 1509 ± 241 kcal/day, which was greater than for Mifflin St Joer 1384 ± 259, Harris-Benedict 1437 ± 244, Katch-McArdle 1345 ± 232 (all p Equation), but less than Cunningham 1557 ± 236 kcal/day. Bland Altman mean bias ranged from -263 to 55 kcal/day. TEE was 1727 (1558-1976) kcal/day, and on multi-variable analysis was positively associated with skeletal muscle mass (β 23.3, p equations underestimate REE in HD patients compared to the HD Equation. TEE was greater in those with higher skeletal muscle mass and protein nitrogen appearance, lower co-morbidity, age, and dialysis vintage, and the employed. More metabolically active patients may require greater dialytic clearances. This article is protected by copyright. All rights reserved.

    Patients on haemodialysis (HD) have a high prevalence of 25-OH-vitamin D (25-OH-D)deficiency. Secondary hyperparathyroidismis a common condition in these patients, which is very important to control. 25-OH-D is involved in regulating calcium homeostasis. As such, appropriate levels of this vitamin could help to control bone mineral metabolism. To evaluate the effect 25-OH-D repletion in HD patients with 25-OH-D deficiency (30ng/ml and 4 between 20-30ng/ml). Parathyroid hormone levels decreased in 32 of the 45 patients, 23 of which (51%) achieved a>30% decrease from baseline. In terms of concomitant treatment, we observed a significant reduction in the selective vitamin D receptor activator dose, but no changes in calcimimetic or phosphate binders administration. In terms of malnutrition-inflammation status, a decrease in C-reactive protein was noted, although other microinflammation parameters, such as activated monocytes (CD14+/CD16+ and CD 14++/CD16+) were unchanged. No changes were observed in the levels of FGF-23. Correcting 25-OH-D deficiency in HD patients is associated with better secondary hyperparathyroidism control with lower doses of vitamin D analogues, as well as an improvement in inflammatory status. Our results support the recommendation to determine 25-OH-D levels and correct its deficiency in these patients. Copyright © 2017 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U.

    Several studies with erythropoiesis-stimulating agents claim that maintenance therapy of renal anaemia may be possible at extended dosing intervals; however, few studies were randomized, results varied, and comparisons between agents were absent. We report results of a multi-national, randomized, prospective trial comparing haemoglobin maintenance with methoxy polyethylene glycol-epoetin beta and darbepoetin alfa administered once monthly. Haemodialysis patients (n = 490) on stable once-weekly intravenous darbepoetin alfa were randomized to methoxy polyethylene glycol-epoetin beta once monthly or darbepoetin alfa every 2 weeks for 26 weeks, with dose adjustment for individual haemoglobin target (11-13 g/dL; maximum decrease from baseline 1 g/dL). Subsequently, patients entered a second 26-week period of once-monthly methoxy polyethylene glycol-epoetin beta and darbepoetin alfa. The primary endpoint was the proportion of patients who maintained average haemoglobin ≥10.5 g/dL, with a decrease from baseline ≤1 g/dL, in Weeks 50-53; the secondary endpoint was dose change over time. The trial is registered at www.ClinicalTrials.gov, number NCT00394953. Baseline characteristics were similar between groups. One hundred and fifty-seven of 245 patients treated with methoxy polyethylene glycol-epoetin beta and 99 of 245 patients with darbepoetin alfa met the response definition (64.1% and 40.4%; P polyethylene glycol-epoetin beta and 58.8% with darbepoetin alfa during once-monthly treatment. Death rates were equal between treatments (5.7%). Most common adverse events included hypertension, procedural hypotension, nasopharyngitis and muscle spasms, with no differences between groups. Methoxy polyethylene glycol-epoetin beta maintained target haemoglobin more successfully than darbepoetin alfa at once-monthly dosing intervals despite dose increases with darbepoetin alfa.

    Dialysis is an expensive therapy, particularly considering its recurrent, protracted nature while patient numbers are also increasing. To afford dialysis for those in need, smarter, more efficient use of limited funds is mandatory. Newer techniques and improved equipment now permit safe, highly effective haemodialysis (HD) at home, alone and while asleep. Indeed, the increase in treatment hours and frequency achieved through nocturnal HD both increase HD efficiency and reduce cardiovascular stress when comparing nocturnal HD (6 nights/week for 8 h/treatment) to conventional daytime HD (4 h/treatment, three times/week). This study compares the expenditure of two distinct HD programmes in the same renal service during the Australian financial year 2003/2004. A conventional satellite HD unit (SHDU) and a nocturnal home HD programme (NHHD(6)) are compared, with both programmes 'notionalised' to 30 patients. The state-derived funding models under which these programmes operate are explained. All wage costs, recurrent expenditure, fixed costs and the estimated costs of building and infrastructure are included. The total NHHD(6) programme expenditure was 33,392 Australian dollars/patient per year (103.82 Australian dollars/treatment) and was 3,892 Australian dollars/patient per year less (a 10.75% saving) when compared with the SHDU expenditure of 36,284 Australian dollars/patient per year (232.58 Australian dollars/treatment). This represented an annual 116,750 Australian dollars programme saving for a 30 patient cohort. Potential additional NHHD(6) savings in erythropoietin, hospitalization and social security dependence were also identified. Home-based therapies are clinically sound, effective and fiscally prudent and efficient. Funding models should reward home-based HD. Health services should encourage home training and support systems, sustaining patients at home wherever possible.

    To analyze if it is worthwhile to screen Brazilian osteoporotic patients for celiac disease (CD). One hundred patients with osteoporosis and 97 controls were evaluated for IgA-EmA (IgA anti-endomysial antibodies) by indirect immunofluorescence method and IgG-anti-tTG (tissue transglutaminase) by ELISA assay. Positive patients were invited to have gastrointestinal endoscopy with jejunal biopsy. Two patients had positive IgG-anti-tTG test and one of them also showed positive IgA-EmA. Only the latter had a positive duodenal biopsy for CD. None of the controls were positive for either auto-antibodies. We observed low prevalence of CD in osteoporotic Brazilian patients. This finding does not support routine screening for CD in patients with osteoporosis in our geographic region.

    Full Text Available Abstract Background Catheter-related bacteraemias (CRBs contribute significantly to morbidity, mortality and health care costs in dialysis populations. Despite international guidelines recommending avoidance of catheters for haemodialysis access, hospital admissions for CRBs have doubled in the last decade. The primary aim of the study is to determine whether weekly instillation of 70% ethanol prevents CRBs compared with standard heparin saline. Methods/design The study will follow a prospective, open-label, randomized controlled design. Inclusion criteria are adult patients with incident or prevalent tunneled intravenous dialysis catheters on three times weekly haemodialysis, with no current evidence of catheter infection and no personal, cultural or religious objection to ethanol use, who are on adequate contraception and are able to give informed consent. Patients will be randomized 1:1 to receive 3 mL of intravenous-grade 70% ethanol into each lumen of the catheter once a week and standard heparin locks for other dialysis days, or to receive heparin locks only. The primary outcome measure will be time to the first episode of CRB, which will be defined using standard objective criteria. Secondary outcomes will include adverse reactions, incidence of CRB caused by different pathogens, time to infection-related catheter removal, time to exit site infections and costs. Prospective power calculations indicate that the study will have 80% statistical power to detect a clinically significant increase in median infection-free survival from 200 days to 400 days if 56 patients are recruited into each arm.

    Catheter-related bacteraemias (CRBs) contribute significantly to morbidity, mortality and health care costs in dialysis populations. Despite international guidelines recommending avoidance of catheters for haemodialysis access, hospital admissions for CRBs have doubled in the last decade. The primary aim of the study is to determine whether weekly instillation of 70% ethanol prevents CRBs compared with standard heparin saline. The study will follow a prospective, open-label, randomized controlled design. Inclusion criteria are adult patients with incident or prevalent tunneled intravenous dialysis catheters on three times weekly haemodialysis, with no current evidence of catheter infection and no personal, cultural or religious objection to ethanol use, who are on adequate contraception and are able to give informed consent. Patients will be randomized 1:1 to receive 3 mL of intravenous-grade 70% ethanol into each lumen of the catheter once a week and standard heparin locks for other dialysis days, or to receive heparin locks only. The primary outcome measure will be time to the first episode of CRB, which will be defined using standard objective criteria. Secondary outcomes will include adverse reactions, incidence of CRB caused by different pathogens, time to infection-related catheter removal, time to exit site infections and costs. Prospective power calculations indicate that the study will have 80% statistical power to detect a clinically significant increase in median infection-free survival from 200 days to 400 days if 56 patients are recruited into each arm. This investigator-initiated study has been designed to provide evidence to help nephrologists reduce the incidence of CRBs in haemodialysis patients with tunnelled intravenous catheters.

    The financial burden of the increasing dialysis population challenges healthcare resources internationally. Home haemodialysis offers many benefits over conventional facility dialysis including superior clinical, patient-centred outcomes and reduced cost. This review updates a previous review, conducted a decade prior, incorporating contemporary home dialysis techniques of frequent and nocturnal dialysis. We sought comparative cost-effectiveness studies of home versus facility haemodialysis (HD) for people with end-stage kidney failure (ESKF). We conducted a systematic review of literature from January 2000-March 2014. Studies were included if they provided comparative information on the costs, health outcomes and cost-effectiveness ratios of home HD and facility HD. We searched medical and health economic databases using MeSH headings and text words for economic evaluation and haemodialysis. Six studies of economic evaluations that compared home to facility HD were identified. Two studies compared home nocturnal HD, one home nocturnal and daily home HD, and three compared contemporary home HD to facility HD. Overall these studies suggest that contemporary home HD modalities are less costly and more effective than facility HD. Home HD start-up costs tend to be higher in the short term, but these are offset by cost savings over the longer term. Contemporaneous dialysis modalities including nocturnal and daily home haemodialysis are cost-effective or cost-saving compared with facility-based haemodialysis. This result is largely driven by lower staff costs, and better health outcomes for survival and quality of life. Expanding the proportion of haemodialysis patients managed at home is likely to produce cost savings. © 2014 Asian Pacific Society of Nephrology.

    Background Few risk scores are available for predicting mortality in chronic kidney disease (CKD) patients undergoing predialysis nephrology care. Here, we developed a risk score using predialysis nephrology practice data to predict 1-year mortality following the initiation of haemodialysis (HD) for CKD patients. Methods This was a multicenter cohort study involving CKD patients who started HD between April 2006 and March 2011 at 21 institutions with nephrology care services. Patients who had not received predialysis nephrology care at an estimated glomerular filtration rate (eGFR) of approximately 10 mL/min per 1.73 m2 were excluded. Twenty-nine candidate predictors were selected, and the final model for 1-year mortality was developed via multivariate logistic regression and was internally validated by a bootstrapping technique. Results A total of 688 patients were enrolled, and 62 (9.0%) patients died within one year of HD initiation. The following variables were retained in the final model: eGFR, serum albumin, calcium, Charlson Comorbidity Index excluding diabetes and renal disease (modified CCI), performance status (PS), and usage of erythropoiesis-stimulating agent (ESA). Their β-coefficients were transformed into integer scores: three points were assigned to modified CCI≥3 and PS 3–4; two to calcium>8.5 mg/dL, modified CCI 1–2, and no use of ESA; and one to albumin7 mL/min per 1.73 m2, and PS 1–2. Predicted 1-year mortality risk was 2.5% (score 0–4), 5.5% (score 5–6), 15.2% (score 7–8), and 28.9% (score 9–12). The area under the receiver operating characteristic curve was 0.83 (95% confidence interval, 0.79–0.89). Conclusions We developed a simple 6-item risk score predicting 1-year mortality after the initiation of HD that might help nephrologists make a shared decision with patients and families regarding the initiation of HD.

    Lithium carbonate is commonly prescribed for the treatment of bipolar (manic-depressive) disorders. However, because of its narrow therapeutic index an excessive elevation of serum lithium concentration, either during chronic maintenance therapy or after an acute overdose, can result in serious toxicity. In addition to supportive care, the established treatment of severe lithium toxicity is haemodialysis. Conventional haemodialysis can reduce serum lithium rapidly, but post-dialysis rebound elevations with recurrent toxicity have been documented in old publications. High-flux membranes should be capable of removing more lithium per hour of haemodialysis, but published values are not available. We report here three patients with acute lithium intoxication who were treated successfully with bicarbonate and high-flux haemodialysis membranes. Our patients presented with a severe degree of intoxication, based on the amount of drug ingested, the initial serum lithium level, the severity of neurologic symptoms and systemic manifestations. Two patients developed acute renal failure probably as a result of volume depletion since it was rapidly reversible by haemodialysis and infusion therapy. In addition, consecutive haemodialysis sessions and improvement of renal function allowed a rapid decrease in serum lithium levels without haemodynamic instability or rebound elevations in lithium concentration. The effectiveness of the procedure in these cases can be attributed to the use of bicarbonate dialysate and high-efficiency dialysers. This is the first report describing the effect of high-efficiency dialysers on lithium pharmacokinetic. Using this technique the elimination rate of lithium was found to be greater than previously reported with haemodialysis.

    Full Text Available Abstract Background The main hypothesis of this study is that patients having regular conventional haemodialysis (HD will have a smaller decline in cardiac systolic function by using cooler dialysate. Cooler dialysate may also be beneficial for brain function. Methods/Design The trial is a multicentre, prospective, randomised, un-blinded, controlled trial. Patients will be randomised 1:1 to use a dialysate temperature of 37°C for 12 months or an individualised cooled dialysate. The latter will be set at 0.5°C less than the patient’s own temperature, determined from the mean of 6 prior treatment sessions with a tympanic thermometer, up to a maximum of 36°C. Protocol adherence will be regularly checked. Inclusion criteria are incident adult HD patients within 180 days of commencing in-centre treatment 3 times per week with capacity to consent for the trial and without contra-indications for magnetic resonance imaging. Exclusion criteria include not meeting inclusion criteria, inability to tolerate magnetic resonance imaging and New York Heart Association Grade IV heart failure. During the study period, resting cardiac and cerebral magnetic resonance imaging will be performed at baseline and 12 months on an inter-dialytic day. Cardiovascular performance during HD will also be assessed by continuous cardiac output monitors, intra-dialytic echocardiography and biomarkers at baseline and 12 months. The primary outcome measure is a 5% between-group difference in left ventricular ejection fraction measured by cardiac magnetic resonance imaging at 12 months compared to baseline. Analysis will be by intention-to-treat. Secondary outcome measures will include changes in cerebral microstructure and changes in cardiovascular performance during HD. A total of 73 patients have been recruited into the trial from four UK centres. The trial is funded by a Research for Patient Benefit Grant from the National Institute of Healthcare Research. AO is

    To evaluate patient satisfaction with pharmaceutical services in Brazilian primary health care. This is a cross-sectional, exploratory, and evaluative study on a representative sample from the five Brazilian geopolitical regions resulting from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). The outcome was the patient's satisfaction, obtained using the item response theory. Associations were tested using Pearson's Chi-square test with sociodemographic and health variables, and multiple logistic regression analyses were carried out. The Hosmer-Lemeshow test was used to verify the adequacy of the final model. Logistic regression results were presented as odds ratio. The overall percentage of patients satisfied with these services was 58.4% (95%CI 54.4-62.3). The "opportunity/convenience" aspect had the lowest satisfaction percentage (49.5%; 95%CI 46.4-52.6) and "interpersonal aspects," the highest percentage (90.5%; 95%CI 88.9-91.8), significantly higher than other aspects. Sex, age group, limitations due to disease, and self-perception of health remained associated in the final multiple logistic model regarding general satisfaction. Most of the interviewed users were satisfied with pharmaceutical services in Brazilian cities, and the satisfaction with the customer's service was determinant in the patient's overall satisfaction.

    We examined 11 pediatric patients with eosinophilic esophagitis with a tardy diagnosis. The symptoms were initially thought to be related to other diseases, leading to the use of inadequate therapeutic approaches. The patients were between 3 and 17 years old (mean 7.8 ± 3.8 years), and 8 of the patients were male. Common symptoms included abdominal pain, regurgitation, difficulty in gaining weight, vomiting, dysphagia, and coughing. The mean age for the onset of symptoms was 4.3 ± 2.9 years. Endoscopic findings included normal mucosa in five (45%) patients, thickening of the mucosa with longitudinal grooves in three (27%), erosive esophagitis in two (18%), and a whitish stippling in one (9%) patient. Treatment included the use of a topical corticosteroid for 10 patients. In eight (73%) cases, the treatment made the symptoms disappear. Ten patients underwent histopathological management after treatment, with a decrease in the number of eosinophils. PMID:24106430

    Full Text Available Mood disorders cause many social problems, often involving family relationships. Few studies are available in the literature comparing patients with bipolar, unipolar, dysthymic, and double depressive disorders concerning these aspects. In the present study, demographic and disease data were collected using a specifically prepared questionnaire. Social adjustment was assessed using the Disability Adjustment Scale and family relationships were evaluated using the Global Assessment of Relational Functioning Scale. One hundred patients under treatment for at least 6 months were evaluated at the Psychiatric Outpatient Clinic of the Botucatu School of Medicine, UNESP. Most patients were women (82% more than 50 (49% years old with at least two years of follow-up, with little schooling (62% had less than 4 years, and of low socioeconomic level. Logistic regression analysis showed that a diagnosis of unipolar disorder (P = 0.003, OR = 0.075, CI = 0.014-0.403 and dysthymia (P = 0.001, OR = 0.040, CI = 0.006-0.275 as well as family relationships (P = 0.002, OR = 0.953, CI = 0914-0.992 played a significant role in social adjustment. Unipolar and dysthymic patients presented better social adjustment than bipolar and double depressive patients (P < 0.001, results that were not due to social class. These patients, treated at a teaching hospital, may represent the severest mood disorder cases. Evaluations were made knowing the diagnosis of the patients, which might also have influenced some of the results. Social disabilities among mood disorder patients are very frequent and intensive.

    Full Text Available OBJECTIVES: The aim of this study was to report the type and frequency of ocular manifestations in Brazilian psoriatic arthritis patients. METHODS: We conducted a cross-sectional study in a Brazilian tertiary hospital. The test group included 40 patients who had psoriatic arthritis according to the Classification Criteria for Psoriatic Arthritis. A control group of 40 individuals was matched for age and gender. All of the patients underwent ophthalmic evaluation, which included best-corrected visual acuity, slit lamp and fundus examinations, and dry eye diagnostic tests (Schirmer I, tear breakup time and rose bengal. Demographic parameters were also evaluated. RESULTS: The mean age of the patients was 53.9±13.1 years; the mean disease duration was 8±10.5 years. Most of the patients were women (60%, and the majority had polyarticular disease (57.5%. Several ocular abnormalities were found, including punctate keratitis, pinguecula, blepharitis, pterygium, cataract, glaucoma, uveitis, and retinal microvascular abnormalities. There were no significant differences in the rates of these abnormalities compared with the control group, however. The Keratoconjunctivitis sicca and dry eye diagnostic tests were more often positive in the patients with psoriatic arthritis than in the control group. CONCLUSIONS: In this study, keratoconjunctivitis sicca was the most common ocular finding related to psoriatic arthritis. Therefore, we recommend early ophthalmologic evaluations for all psoriatic arthritis patients who complain of eye symptoms.

    Secondary hyperparathyroidism (SHPT) is a major complication associated with chronic kidney disease. We evaluated the efficacy and safety of etelcalcetide (ONO-5163/AMG 416), a novel intravenous calcimimetic, in Japanese haemodialysis patients with SHPT. In this phase 3, multicentre, randomized, double-blind, placebo-controlled, parallel-group study, etelcalcetide was administered three times per week at an initial dose of 5 mg, and subsequently adjusted to doses between 2.5 and 15 mg at 4-week intervals for 12 weeks. A total of 155 SHPT patients with serum intact parathyroid hormone (iPTH) levels ≥300 pg/mL were assigned to receive etelcalcetide (n = 78) or placebo (n = 77). The primary endpoint was the proportion of patients with decreased serum iPTH to the target range proposed by the Japanese Society for Dialysis Therapy (60-240 pg/mL). The major secondary endpoint was the proportion of patients with ≥30% reductions in serum iPTH from baseline. The proportion of patients meeting the primary endpoint was significantly higher for etelcalcetide (59.0%) versus placebo (1.3%). Similarly, the proportion of patients meeting the major secondary endpoint was significantly higher for etelcalcetide (76.9%) versus placebo (5.2%). Serum albumin-corrected calcium, phosphorus and intact fibroblast growth factor-23 levels were decreased in the etelcalcetide group. Nausea, vomiting and symptomatic hypocalcaemia were mild with etelcalcetide. Serious adverse events related to etelcalcetide were not observed. This study demonstrated the efficacy and safety of etelcalcetide. As the only available intravenous calcium-sensing receptor agonist, etelcalcetide is likely to provide a new treatment option for SHPT in haemodialysis patients.

    Conclusions: The resistance mutational profile of Brazilian patients failing antiretroviral therapy is quite variable, depending on the city where patients were tested. This variation likely reflects distinctive choice of antiretrovirals drugs to initiate therapy, adherence to specific drugs, or circulating HIV-1 strains. Overall, etravirine and DRV/r remain as the most active drugs.

    To explore the concepts of empathy and stress in nurses working in haemodialysis units in France and their possible interactions. Nurses' work in haemodialysis is rather complex. It requires technical expertise, because of the peculiarity of the treatment, and emotional skills, to care for patients throughout a long-lasting therapy. Empathy is considered as a key in the concept of caring, which allows nurses to give appropriate answers to their patients' needs. In addition, nurses' work environment can generate stress. A qualitative descriptive design. Nurses (N = 23) working in haemodialysis units were interviewed in three different sites in 2014. The analysis of nurses' speech emphasized a predominance of the cognitive attributes of empathy: understanding, communication, adjusted response (43%), and a special feature of the relationship due to the chronicity of the care (23%). The main stressors highlighted were time management (14%), emergencies (12%) and technical nature of the task (8%). Nurses' experience in haemodialysis seemed to be a modulating factor regarding empathy and stress. The main stressors highlighted were time management (14%), emergencies (12%) and technical nature of the task (8%). Nurses' experience in haemodialysis seemed to be a modulating factor regarding empathy and stress. The results showed the special features of nurses' work in haemodialysis and the need for further studies to investigate these concepts. The influence of stress on empathy needs to be explored more precisely, especially regarding nurses' experience and its impact on patients. © 2016 John Wiley & Sons Ltd.

    Full Text Available Human leukocyte antigens (HLA have a pivotal role in immune response and may be involved in antigen recognition of periodontal pathogens. However, the associations of HLA with chronic periodontitis (CP have not been previously studied in the Brazilian population. In an attempt to clarify the issue of genetic predisposition to CP, we examined the distribution of HLA alleles, genotypes, and haplotypes in patients from Southern Brazil. One hundred and eight CP patients and 151 healthy and unrelated controls with age-, gender-, and ethnicity-matched were HLA investigated by polymerase chain reaction with sequence specific oligonucleotides. To exclude smoking as a predisposing factor, statistical analyses were performed in the total sample and in nonsmoking individuals. The significant results showed a positive association of the A∗02/HLA-B∗40 haplotype with CP (total samples: 4.2% versus 0%, Pc = 0.03; nonsmokers: 4.3% versus 0%, Pc = 0.23 and a lower frequency of HLA-B∗15/HLA-DRB1∗11 haplotype in CP compared to controls (total samples: 0.0% versus 4.3%, Pc = 0.04; nonsmokers: 0 versus 5.1%, Pc = 1.0. In conclusion, the HLA-A∗02/B∗40 haplotype may contribute to the development of CP, while HLA-B∗15/DRB1∗11 haplotype might indicate resistance to disease among Brazilians.

    Full Text Available Abstract Background Renal failure is a frequent complication of multiple myeloma and when severe is associated with a greatly increased morbidity and mortality. The principal cause of severe renal failure is cast nephropathy, a direct consequence of high concentrations of monoclonal free light chains (FLCs in patients' sera. FLC removal by extended haemodialysis, using a high cut-off dialyser, has recently been described as a novel therapeutic option. Methods The EUropean trial of free LIght chain removal by exTEnded haemodialysis in cast nephropathy (EuLITE trial is a prospective, randomised, multicentre, open label clinical trial to investigate the clinical benefits of FLC removal haemodialysis in patients with cast nephropathy, dialysis dependent acute renal failure and de novo multiple myeloma. Recruitment commenced in May 2008. In total, 90 patients will be recruited. Participants will be randomised, centrally, upon enrolment, to either trial chemotherapy and FLC removal haemodialysis or trial chemotherapy and standard high flux haemodialysis. Trial chemotherapy consists of bortezomib, doxorubicin and dexamethasone. FLC removal haemodialysis is undertaken with two Gambro HCO 1100 dialysers in series using an intensive treatment schedule. The primary outcome for the study is independence of dialysis at 3 months. Secondary outcomes are: duration of dialysis, reduction in serum FLC concentrations; myeloma response and survival. Hypothesis FLC removal haemodialysis will increase the rate of renal recovery in patients with severe renal failure secondary to cast nephropathy in de novo multiple myeloma.

    To test an explanatory model of the relationships between the nursing work environment, job satisfaction, job stress and emotional exhaustion for haemodialysis nurses, drawing on Kanter's theory of organizational empowerment. Understanding the organizational predictors of burnout (emotional exhaustion) in haemodialysis nurses is critical for staff retention and improving nurse and patient outcomes. Previous research has demonstrated high levels of emotional exhaustion among haemodialysis nurses, yet the relationships between nurses' work environment, job satisfaction, stress and emotional exhaustion in this population are poorly understood. A cross-sectional online survey. 417 nurses working in haemodialysis units completed an online survey between October 2011-April 2012 using validated measures of the work environment, job satisfaction, job stress and emotional exhaustion. Overall, the structural equation model demonstrated adequate fit and we found partial support for the hypothesized relationships. Nurses' work environment had a direct positive effect on job satisfaction, explaining 88% of the variance. Greater job satisfaction, in turn, predicted lower job stress, explaining 82% of the variance. Job satisfaction also had an indirect effect on emotional exhaustion by mitigating job stress. However, job satisfaction did not have a direct effect on emotional exhaustion. The work environment of haemodialysis nurses is pivotal to the development of job satisfaction. Nurses' job satisfaction also predicts their level of job stress and emotional exhaustion. Our findings suggest staff retention can be improved by creating empowering work environments that promote job satisfaction among haemodialysis nurses. © 2014 John Wiley & Sons Ltd.

    Full Text Available Patients with chronic renal insufficiency (CRI have reduced hemoglobin levels, mostly as a result of decreased kidney production of erythropoietin, but the relation between renal insufficiency and the magnitude of hemoglobin reduction has not been well defined. Hereditary hemochromatosis is an inherited disorder of iron metabolism. The importance of the association of hemochromatosis with treatment for anemia among patients with CRI has not been well described. We analyzed the frequency of the C282Y and H63D mutations in the HFE gene in 201 Brazilian individuals with CRI undergoing hemodialysis. The analysis of the effects of HFE mutations on iron metabolism and anemia with biochemical parameters was possible in 118 patients of this study (hemoglobin, hematocrit, ferritin levels, transferrin saturation, and serum iron. A C282Y heterozygous mutation was found in 7/201 (3.4% and H63D homozygous and heterozygous mutation were found in 2/201 (1.0% and 46/201 (22.9%, respectively. The allelic frequencies of the HFE mutations (0.017 for C282Y mutation and 0.124 for H63D mutation did not differ between patients with CRI and healthy controls. Regarding the biochemical parameters, no differences were observed between HFE heterozygous and mutation-negative patients, although ferritin levels were not higher among patients with the H63D mutation (P = 0.08. From what we observed in our study, C282Y/H63D HFE gene mutations are not related to degrees of anemia or iron stores in CRI patients receiving intravenous iron supplementation (P > 0.10. Nevertheless, the present data suggest that the H63D mutation may have an important function as a modulating factor of iron overload in these patients.

    Full Text Available Background/Aims: Volume overload, frequently clinically asymptomatic is considered as a causative factor limiting the effectiveness of antihypertensive therapy in haemodialysis (HD patients. Therefore, the aim of this study was to assess plasma levels of N-terminal fragment of the prohormone brain natriuretic peptide (NT-proBNP and a C-terminal portion of the precursor of vasopressin (CT-proAVP, copeptin, surrogate markers of volume overload in HD patients in relation to the number of antihypertensive drugs used in the hypertension treatment. Methods: One hundred and fifty adult HD patients (92 males were enrolled into this study. Clinical data concerning blood pressure (BP measurements prior haemodialysis session and pharmacotherapy were collected from all patients. In addition to routine laboratory parameters, plasma levels of NT-proBNP and CT-proAVP were measured, and daily sodium and water consumption were estimated with a portion-size food frequency questionnaire. Results: Among 145 (96.7% hypertensive HD patients, 131 were receiving antihypertensive medication. Despite antihypertensive therapy, 31.0% had inadequate BP control. Plasma concentration of NT-proBNP was associated with systolic (R=0.19; p=0.02 but not diastolic BP values and with the number of received antihypertensive drugs (R=0.21; p=0.01. The highest NT-proBNP values were observed in patients receiving 3 or more antihypertensive drugs. In contrast, no significant correlation was found between plasma CT-proAVP concentrations and BP values as well as and the number of antihypertensive drugs. Receiver operator curve analysis showed that NT-proBNP values over 13,184 pg/mL predicted the use of at least 3 antihypertensive drugs in maximal doses in the therapy of hypertension, similar analyses performed for CT-proAVP showed much less specificity. Conclusions: 1. Increased levels of NT-proBNP seems to be a better biomarker of multidrug antihypertensive therapy requirement than CT

    A focused and commented review on the impact of dermatologic diseases and interventions in the solidary act of donating blood is presented to dermatologists to better advise their patients. This is a review of current Brazilian technical regulations on hemotherapeutic procedures as determined by Ministerial Directive #1353/2011 by the Ministry of Health and current internal regulations of the Hemotherapy Center of Ribeirão Preto, a regional reference center in hemotherapeutic procedures. Criteria for permanent inaptitude: autoimmune diseases (>1 organ involved), personal history of cancer other than basal cell carcinoma, severe atopic dermatitis or psoriasis, pemphigus foliaceus, porphyrias, filariasis, leprosy, extra pulmonary tuberculosis or paracoccidioidomycosis, and previous use of etretinate. Drugs that impose temporary ineligibility: other systemic retinoids, systemic corticosteroids, 5-alpha-reductase inhibitors, vaccines, methotrexate, beta-blockers, minoxidil, anti-epileptic, and anti-psychotic drugs. Other conditions that impose temporary ineligibility: occupational accident with biologic material, piercing, tattoo, sexually transmitted diseases, herpes, and bacterial infections, among others. Thalidomide is currently missing in the teratogenic drugs list. Although finasteride was previously considered a drug that imposed permanent inaptitude, according to its short halflife current restriction of 1 month is still too long. Dermatologists should be able to advise their patients about proper timing to donate blood, and discuss the impact of drug withdrawal on treatment outcomes and to respect the designated washout periods.

    Vegetarian diets have long been thought of as beneficial to health. However, vegetarian diets are often low in protein, which is contradictory to the high protein diet guideline for uraemia patients. The purpose of the study was to investigate the impact of a vegetarian diet on the nutritional status of haemodialysis (HD) patients. Patients on chronic HD for over 6 months were included in the study. The normalized protein catabolic rate (nPCR) was used to reflect daily protein intake. Biochemical markers of nutrition, anthropometric parameters, subjective global assessment (SGA) and functional activity of daily living were assessed to evaluate the nutritional status of vegetarians on chronic HD. Nineteen out of 318 HD patients were vegetarians. The nPCR was lower in the vegetarian group (1.20 ± 0.24 vs 1.10 ± 0.29 g/kg per day, non-Veg vs Veg, P vegetarian and non-vegetarian HD patients. The body mass index (BMI) and mid-arm muscular circumference (MAMC) were lower in vegetarian patients (P vegetarians can be maintained at a level similar to that of non-vegetarian patients but erythropoietin doses needed were higher in vegetarian patients (P vegetarians and non-vegetarians. The present study revealed that HD patients on vegetarian diets might have a smaller BMI, but SGA and function of daily activities were similar to those of the non-vegetarians. The haematocrit of vegetarians can be maintained with a higher erythropoietin dose. © 2011 The Authors. Nephrology © 2011 Asian Pacific Society of Nephrology.

    Retinal dystrophies constitute a group of diseases characterized by clinical variability and pronounced genetic heterogeneity. Retinitis pigmentosa is the most common subtype of hereditary retinal dystrophy and is characterized by a progressive loss of peripheral field vision (Tunnel Vision), eventual loss of central vision, and progressive night blindness. The characteristics of the fundus changes include bone-spicule formations, attenuated blood vessels, reduced and/or abnormal electroretinograms, changes in structure imaged by optical coherence tomography, and subjective changes in visual function. The different syndromic and nonsyndromic forms of retinal dystrophies can be attributed to mutations in more than 250 genes. Molecular diagnosis for patients with retinitis pigmentosa has been hampered by extreme genetic and clinical heterogeneity between retinitis pigmentosa and other forms of retinal dystrophies. Next generation sequencing (NGS) technologies are among the most promising techniques to identify pathogenic variations in retinal dystrophies. The purpose of this study was to discover the molecular diagnosis for Brazilian patients clinically diagnosed with a retinitis pigmentosa pattern of inheritance by using NGS technologies. Sixteen patients with the clinical diagnosis of retinitis pigmentosa were included in the study. Their DNA was sequenced in a panel with 132 genes related to retinal dystrophies using the Illumina® platform. Sequence analysis and variation calling was performed using Soft Genetics®, NextGene, and Geneticist Assistant software. The criteria for pathogenicity analysis were established according to the results of prediction programs (Polyphen 2, Mutation taster and MetaCore™) and comparison of pathogenic variations found with databases. The identified potentially pathogenic variations were all confirmed by Sanger sequencing. There were 89 variations predicted as pathogenic, but only 10 of them supported the conclusion of the

    Hepatitis C virus infection (HCV) is not infrequent among haemodialysis patients. Most published reports suggest that patient-to-patient spread, either directly or indirectly, is the most common mode of transmission in renal units. To investigate the source of an outbreak, and the route of transmission, of acute HCV infection in two Scottish patients occurring within eight weeks of receiving haemodialysis in the same unit while on holiday in Majorca. This was an international epidemiological and molecular investigation of HCV infection among a cohort of haemodialysis patients from nine countries. No further HCV-positive infections were observed among residents and holidaymakers receiving haemodialysis at the unit in Majorca. Molecular investigations confirmed that a Spanish healthcare worker (HCW) was the source of infection for the two Scottish patients. The investigators were unable to determine the route of transmission. This outbreak is the first reported case of HCW-to-patient transmission of HCV in a renal unit, and the third reported case of transmission involving a HCW who had not performed invasive procedures. The issue of whether renal units are an exceptional case with regards to the risk of transmission associated with non-invasive procedures should be considered, in conjunction with the need to improve surveillance of blood-borne virus transmissions in renal units in the UK and abroad.

    Haemodialysis nurses form long term relationships with patients in a technologically complex work environment. Previous studies have highlighted that haemodialysis nurses face stressors related to the nature of their work and also their work environments leading to reported high levels of burnout. Using Kanters (1997) Structural Empowerment Theory as a guiding framework, the aim of this study was to explore the factors contributing to satisfaction with the work environment, job satisfaction, job stress and burnout in haemodialysis nurses. Using a sequential mixed-methods design, the first phase involved an on-line survey comprising demographic and work characteristics, Brisbane Practice Environment Measure (B-PEM), Index of Work Satisfaction (IWS), Nursing Stress Scale (NSS) and the Maslach Burnout Inventory (MBI). The second phase involved conducting eight semi-structured interviews with data thematically analyzed. From the 417 nurses surveyed the majority were female (90.9 %), aged over 41 years of age (74.3 %), and 47.4 % had worked in haemodialysis for more than 10 years. Overall the work environment was perceived positively and there was a moderate level of job satisfaction. However levels of stress and emotional exhaustion (burnout) were high. Two themes, ability to care and feeling successful as a nurse, provided clarity to the level of job satisfaction found in phase 1. While two further themes, patients as quasi-family and intense working teams, explained why working as a haemodialysis nurse was both satisfying and stressful. Nurse managers can use these results to identify issues being experienced by haemodialysis nurses working in the unit they are supervising.

    Theophylline overdose can result in significant cardiovascular and neurologic toxicity and is potentially fatal. Clearance of theophylline can be enhanced by the administration of multiple-dose activated charcoal (MDAC) and extracorporeal elimination techniques. We report a case of severe theophylline toxicity initially treated with MDAC and intermittent haemodialysis. Subsequent to this, sustained low-efficiency dialysis (SLED) was undertaken. This is a prolonged renal replacement therapy that uses blood and dialysate flow rates between those of intermittent haemodialysis and continuous renal replacement therapy. A 61-year-old man presented following ingestion of 24 g of theophylline SR (300 mg/kg), 240 mg of diazepam and 2 g of gabapentin. He required intubation and developed a supraventricular tachycardia treated with esmolol, but suffered no seizures. Serum theophylline concentration peaked at 636 μmol/L (55-110) at 9.5 h post-ingestion. Intermittent haemodialysis was performed for 4 h and resulted in a theophylline extraction ratio of 0.57 with elimination half-life of 2.3 h. SLED was subsequently performed on two occasions for 7 h. Theophylline extraction ratio ranged from 0.46 (half-life 5.3 h during the first cycle) to 0.61 (half-life 10.6 h during the second cycle). After cessation of SLED, elimination half-life was 26 h. The patient made an uneventful recovery. Intermittent haemodialysis is the current recommended extracorporeal technique for enhancing theophylline elimination in the absence of charcoal haemoperfusion. However, SLED produced similar apparent extraction ratios with longer associated elimination half-life for theophylline than for intermittent haemodialysis. SLED is undertaken by intensive care unit (ICU) staff and may be a useful extracorporeal elimination technique in cases where access to intermittent haemodialysis, requiring specialist dialysis nursing staff, is limited or may be delayed.

    Full Text Available Summary Objective: The purpose of this study was to translate, culturally validate and evaluate the Patients Concerns Inventory - Head and Neck (PCI-H&N in a consecutive series of Brazilian patients. Method: This study included adult patients treated for upper aerodigestive tract (UADT cancer. The translation and cultural adaptation of the PCI-H&N followed internationally accepted guidelines and included a pretest sample of patients that completed the first Brazilian Portuguese version of the PCI. Use, feasibility and acceptability of the PCI were tested subsequently in a consecutive series of UADT cancer patients that completed the final Brazilian Portuguese version of the PCI and a Brazilian Portuguese version of the University of Washington Quality of Life Questionnaire (UW-QOL. Associations between physical and socio-emotional composite scores from the UW-QOL and the PCI were analyzed. Results: Twenty (20 patients participated in the pretest survey (translation and cultural adaptation process, and 84 patients were analyzed in the cultural validation study. Issues most selected were: fear of cancer returning, dry mouth, chewing/eating, speech/voice/being understood, swallowing, dental health/teeth, anxiety, fatigue/tiredness, taste, and fear of adverse events. The three specialists most selected by the patients for further consultation were speech therapist, dentist and psychologist. Statistically significant relationships between PCI and UW-QOL were found. Conclusion: The translation and cultural adaptation of the PCI into Brazilian Portuguese language was successful, and the results demonstrate its feasibility and usefulness, making this a valuable tool for use among the Brazilian head and neck cancer population.

    Propolis contains a variety of bioactive components and possesses many biological properties. This study was designed to evaluate potential effects of Brazilian green propolis on glucose metabolism and antioxidant function in patients with type 2 diabetes mellitus (T2DM). In the 18-week randomized controlled study, enrolled patients with T2DM were randomly assigned to Brazilian green propolis group (900 mg/day) (n = 32) and control group (n = 33). At the end of the study, no significant difference was found in serum glucose, glycosylated hemoglobin, insulin, aldose reductase or adiponectin between the two groups. However, serum GSH and total polyphenols were significantly increased, and serum carbonyls and lactate dehydrogenase activity were significantly reduced in the Brazilian green propolis group. Serum TNF-α was significantly decreased, whereas serum IL-1β and IL-6 were significantly increased in the Brazilian green propolis group. It is concluded that Brazilian green propolis is effective in improving antioxidant function in T2DM patients.

    Full Text Available Abstract Background Tunnelled central venous dialysis catheter use is significantly limited by the occurrence of catheter-related infections. This randomised controlled trial assessed the efficacy of a 48 hour 70% ethanol lock vs heparin locks in prolonging the time to the first episode of catheter related blood stream infection (CRBSI. Methods Patients undergoing haemodialysis (HD via a tunnelled catheter were randomised 1:1 to once per week ethanol locks (with two heparin locks between other dialysis sessions vs thrice per week heparin locks. Results Observed catheter days in the heparin (n=24 and ethanol (n=25 groups were 1814 and 3614 respectively. CRBSI occurred at a rate of 0.85 vs. 0.28 per 1000 catheter days in the heparin vs ethanol group by intention to treat analysis (incident rate ratio (IRR for ethanol vs. heparin 0.17; 95%CI 0.02-1.63; p=0.12. Flow issues requiring catheter removal occurred at a rate of 1.6 vs 1.4 per 1000 catheter days in the heparin and ethanol groups respectively (IRR 0.85; 95% CI 0.20-3.5 p =0.82 (for ethanol vs heparin. Conclusions Catheter survival and catheter-related blood stream infection were not significantly different but there was a trend towards a reduced rate of infection in the ethanol group. This study establishes proof of concept and will inform an adequately powered multicentre trial to definitively examine the efficacy and safety of ethanol locks as an alternative to current therapies used in the prevention of catheter-associated blood stream infections in patients dialysing with tunnelled catheters.

    Vascular access for haemodialysis is key in renal patients both due to its associated morbidity and mortality and due to its impact on quality of life. The process, from the creation and maintenance of vascular access to the treatment of its complications, represents a challenge when it comes to decision-making, due to the complexity of the existing disease and the diversity of the specialities involved. With a view to finding a common approach, the Spanish Multidisciplinary Group on Vascular Access (GEMAV), which includes experts from the five scientific societies involved (nephrology [S.E.N.], vascular surgery [SEACV], vascular and interventional radiology [SERAM-SERVEI], infectious diseases [SEIMC] and nephrology nursing [SEDEN]), along with the methodological support of the Cochrane Center, has updated the Guidelines on Vascular Access for Haemodialysis, published in 2005. These guidelines maintain a similar structure, in that they review the evidence without compromising the educational aspects. However, on one hand, they provide an update to methodology development following the guidelines of the GRADE system in order to translate this systematic review of evidence into recommendations that facilitate decision-making in routine clinical practice, and, on the other hand, the guidelines establish quality indicators which make it possible to monitor the quality of healthcare.

    Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in

    Full Text Available Patients undergoing haemodialysis treatment have a high burden of disease (particularly cardiovascular comorbidities affecting their quality of life and dramatically shortening life expectancy. Effective chronic kidney disease (CKD control requires regular preventive medication and a response to that medication. Poor receptiveness to CKD medication can be related to individual variability in the dose needed to achieve a response, as well as to low-adherent behaviour in relation to the CKD medication regimen. Some patients, though not many, according to studies' findings, abuse the medical regimen as a result of suicidal tendencies. The present case gave us the opportunity to consider the causes and clinical findings and review the specific psychological interventions for patients with CKD.

    Full Text Available Aryl hydrocarbon receptor-interacting protein (AIP gene mutations (AIPmut are the most frequent germline mutations found in apparently sporadic pituitary adenomas (SPA. Our aim was to evaluate the frequency of AIPmut among young Brazilian patients with SPA. We performed an observational cohort study between 2013 and 2016 in a single referral center. AIPmut screening was carried out in 132 SPA patients with macroadenomas diagnosed up to 40 years or in adenomas of any size diagnosed until 18 years of age. Twelve tumor samples were also analyzed. Leukocyte DNA and tumor tissue DNA were sequenced for the entire AIP-coding region for evaluation of mutations. Eleven (8.3% of the 132 patients had AIPmut, comprising 9/74 (12% somatotropinomas, 1/38 (2.6% prolactinoma, 1/10 (10% corticotropinoma and no non-functioning adenomas. In pediatric patients (≤18 years, AIPmut frequency was 13.3% (2/15. Out of the 5 patients with gigantism, two had AIPmut, both truncating mutations. The Y268* mutation was described in Brazilian patients and the K273Rfs*30 mutation is a novel mutation in our patient. No somatic AIP mutations were found in the 12 tumor samples. A tumor sample from an acromegaly patient harboring the A299V AIPmut showed loss of heterozygosity. In conclusion, AIPmut frequency in SPA Brazilian patients is similar to other populations. Our study identified two mutations exclusively found in Brazilians and also shows, for the first time, loss of heterozygosity in tumor DNA from an acromegaly patient harboring the A299V AIPmut. Our findings corroborate previous observations that AIPmut screening should be performed in young patients with SPA.

    The Cardiac Patients Learning Needs Inventory (CPLNI) was constructed to assess the learning needs of patients with cardiac disease. This study aimed to compare the results of semantic validations of the CPLNI version adapted to Portuguese, involving 40 Brazilian and 16 Portuguese patients hospitalized for coronary artery disease treatment. The participants were individually interviewed and answered to sociodemographic and clinic characterization instrument, to the adapted CPLNI, and to the semantic validation instrument. In CPLNI's general assessment, most patients, both Brazilians and Portuguese, considered the instrument adequate, easy to understand and complete. The semantic validation of the CPLNI showed the need for some changes in its writing with a view to the semantic adaptation of the instrument for use in Portugal and Brazil.

    We compared sociodemographic characteristics and psychiatric status in obese Brazilian patients who did (n=32) and did not (n=33) meet DSM-IV criteria for binge-eating disorder (BED). The sample's mean age was 35.0 years (+/-10.5), with 92.3% of individuals being female and 41.5% having some higher education. Obese binge eaters (OBE) were significantly more likely than obese non-binge eaters to meet criteria for a current diagnosis of any axis I disorder, any mood disorder and any anxiety disorder. Specifically, OBE patients were characterized by significantly higher rates of current and lifetime histories of major depressive disorder. Similar to patients from developed countries, Brazilian patients with BED display increased rates of psychiatric comorbidity, particularly mood and anxiety disorders.

    BACKGROUND: Although arteriovenous fistulas (AVFs) are actively promoted, their use at the start of haemodialysis (HD) seems to be decreasing worldwide. In this paper, we describe recent trends in incidence and prevalence of vascular access types in Europe from 2005 to 2009 and their relationship...... with patient characteristics and survival. METHODS: Ten European renal registries participating in the ERA-EDTA Registry provided data on incidence (n = 13,044) and/or prevalence (n = 75,715) of vascular access types. We used logistic regression to assess which factors influence the likelihood to be treated...... for the prevalence; use of AVFs decreased from 66 to 62% and use of CVCs increased from 28 to 32%. There was a large international variation in the use of the different vascular access types. Female patients [adjusted odds ratio: 0.84, 95% confidence interval (CI): 0.78-0.90] and those ≥80 years (0.77, 95% CI: 0...

    The Behavioral Pain Scale is a pain assessment tool for uncommunicative and sedated Intensive Care Unit patients. The lack of a Brazilian scale for pain assessment in adults mechanically ventilated justifies the relevance of this study that aimed to validate the Brazilian version of Behavioral Pain Scale as well as to correlate its scores with the records of physiological parameters, sedation level and severity of disease. Twenty-five Intensive Care Unit adult patients were included in this study. The Brazilian Behavioral Pain Scale version (previously translated and culturally adapted) and the recording of physiological parameters were performed by two investigators simultaneously during rest, during eye cleaning (non-painful stimulus) and during endotracheal suctioning (painful stimulus). High values of responsiveness coefficient (coefficient=3.22) were observed. The Cronbach's alpha of total Behavioral Pain Scale score at eye cleaning and endotracheal suctioning was 0.8. The intraclass correlation coefficient of total Behavioral Pain Scale score was ≥ 0.8 at eye cleaning and endotracheal suctioning. There was a significant highest Behavioral Pain Scale score during application of painful procedure when compared with rest period (p≤0.0001). However, no correlations were observed between pain and hemodynamic parameters, sedation level, and severity of disease. This pioneer validation study of Brazilian Behavioral Pain Scale exhibits satisfactory index of internal consistency, interrater reliability, responsiveness and validity. Therefore, the Brazilian Behavioral Pain Scale version was considered a valid instrument for being used in adult sedated and mechanically ventilated patients in Brazil.

    Full Text Available Abstract Background Frequent and long-term commuting is a requirement for dialysis patients. Accessibility thus affects their quality of lives. In this paper, a new model for accessibility measurement is proposed in which both geographic distance and facility capacity are taken into account. Simulation of closure of rural facilities and that of capacity transfer between urban and rural facilities are conducted to evaluate the impacts of these phenomena on equity of accessibility among dialysis patients. Methods Post code information as of August 2011 of all the 7,374 patients certified by municipalities of Hiroshima prefecture as having first or third grade renal disability were collected. Information on post code and the maximum number of outpatients (capacity of all the 98 dialysis facilities were also collected. Using geographic information systems, patient commuting times were calculated in two models: one that takes into account road distance (distance model, and the other that takes into account both the road distance and facility capacity (capacity-distance model. Simulations of closures of rural and urban facilities were then conducted. Results The median commuting time among rural patients was more than twice as long as that among urban patients (15 versus 7 minutes, p  Conclusions Closures of dialysis facilities in rural areas have a substantially larger impact on equity of commuting times among dialysis patients than closures of urban facilities. The accessibility simulations using thecapacity-distance model will provide an analytic framework upon which rational resource distribution policies might be planned.

    Full Text Available The profile of patients undergoing haemodialysis in the dialysis unit of Hospital Santa Casa de Maringá, Maringá PR Brazil, is provided. A questionnaire on social and economic data and underlying diseases prior to the Chronic Kidney Disease (CKD identified the patients’ profile. The project was approved by the Ethics Committee of the institution. Eighty-three patients, with 54.21% males, were interviewed. Age bracket ranged between 20 and 59 years in 65.06% of patients. Only 27.71% maintained jobs after the diagnosis and the start of treatment; 63.86% had an average personal income between 1 and 3 minimum wages; 63.85% did not practice any physical activity. Moreover, 53.01% belonged to the European-Brazilian white group; 20.48% to the Afro-Brazilian brown group; 19.28% to the Afro-Brazilian Negro group; 6.02% to other ethnic groups. Further, 85.54% patients reported having an underlying disease prior to the CKD, namely, 61.45% were hypertensive; 31.33% were diabetics and 20.48% had other diseases.

    To describe and elucidate the meanings of being a close relative of a severely ill family member treated with maintenance haemodialysis approaching the end of life. End-stage renal disease together with comorbidities, haemodialysis treatment and high mortality rates also affects the lives of close relatives, who report burdens and impaired quality of life. To improve care, more understanding is needed of close relatives' experiences during these patients' end of life. This study has a qualitative interpretative design. Fourteen retrospective qualitative interviews were conducted with close relatives (aged 48-93 years) of deceased patients who had been treated with haemodialysis. The interview text was interpreted using a phenomenological hermeneutical method in three phases. The findings of the structural analysis were formulated as six themes: Striving to be supportive and helpful without doing harm to the ill person's self; Needing increasing strength and support; Balancing the will to help with one's own ongoing life; Increasing responsibility involving dilemmas; Striving for a good life together in the present and Living with awareness of death. Close relatives strive for balance and well-being accompanying their ill family member through the end of life. They are facing moral dilemmas and growing demands as their responsibility increases with the deterioration of their family member. Support from and interaction with the healthcare professionals is then of significance. Findings challenge healthcare professionals in haemodialysis settings to identify close relatives' individual resources and needs towards the patients' end of life. Healthcare professionals in haemodialysis settings need to offer close relatives opportunities to talk about the future and what may be expected at end of life, with or without haemodialysis. They should also contact the closest relative after the death as they may need confirmation and closure. © 2014 John Wiley & Sons Ltd.

    Haemodialysis patients are at risk of gram-positive bacteraemia and commonly require intravenous vancomycin. Intravenously administered vancomycin is primarily excreted by the kidney and exhibits complex pharmacokinetics in haemodialysis patients; achieving therapeutic levels can be challenging. An audit in our unit showed current practises of vancomycin administration resulted in a high proportion of sub-therapeutic levels. A new protocol was developed with fixed weight-based loading and subsequent dosing guided by pre-dialysis levels, target levels were 10-20mg\\/L. Its effectiveness was prospectively evaluated between 24th September 2012, and 8th February 2013. During this period 25 patients commenced vancomycin, 15 were included. In total, 112 vancomycin levels were taken, 94 (84%) were therapeutic, this was a significant improvement compared to previous practise (odds ratio 5.4, CI 3.1-9.4, p < 0.0001). In conclusion, our study shows this protocol can consistently and reliably achieve therapeutic vancomycin levels

    This study aimed to evaluate the possible association between periodontitis and systemic complications in a Brazilian type 1 diabetes population. A multicentre, sectional study was carried out in 28 public clinics located in 20 Brazilian cities. Data from 3,591 patients were obtained (56.0% females, 57.2% Caucasians), with an average age of 21.2 ± 11.7 years and whose mean duration of type 1 diabetes was 9.6 ± 8.1 years. Periodontitis was evaluated through self-report. Odds ratios (OR) and 95% confidence intervals were calculated to evaluate the association between periodontitis and systemic diabetes complications (chronic micro and macrovascular complications and hospitalizations by hyperglycemia and diabetic ketoacidosis). The prevalence of periodontitis was 4.7% (n=170). Periodontitis patients had mean age of 27.4 ± 12.9. This group was older (pperiodontitis. Systolic and diastolic blood pressures were significantly increased in periodontitis patients (pPeriodontitis patients had increased odds of microvascular complications (2.43 [1.74-3.40]) and of hospitalizations related to hyperglycemia (2.76 [1.72-4.42]) and ketoacidosis (2.72 [1.53-4.80]). In conclusion, periodontitis was associated to systemic complications in Brazilian type 1 diabetes patients.

    All arteriovenous fistula/grafts options should be exhausted before haemodialysis is carried out via central venous catheters (CVC). CVCs carry high morbidity and mortality risks and in some patients, the central veins could be exhausted. In these patients, an arterioarterial prosthetic loop (AAPL) or straight graft can be the only option for haemodialysis. A systematic review was thus carried out to look at the use of arterioarterial graft for haemodialysis, with regards to dialysis adequacy, complications, and patency rates. An electronic search was performed using the EMBASE and MEDLINE databases from inception until June 2017. Study retrieval was conducted according to PRISMA guidelines. A total of eight studies published between 1976 and 2017 were identified for pooled analysis. The studies were retrospective cohort in design and reported data on 151 patients. Primary patency rate ranged from 67%-94.5% at six months to 54%-61% at 36 months, with secondary patency rates from 83%-93% at six months to 72%-87% at 36 months. All studies documented satisfactory haemodialysis. Although limited by the size of the cohort of patients studied, patients with end-to-side grafts did not suffer from distal ischaemia when the graft occluded unlike patients who had their graft sutured as end-to-end. This review highlights the potential benefit of arterioarterial grafts for dialysis as an alternative vascular access option. As a result, this review calls for registry-based multicentre study to evaluate this treatment arm as an alternative option when all AVF/AVG options are exhausted.

    There is a need to improve end-of-life care for people with end-stage kidney disease, particularly due to the increasingly elderly, frail and co-morbid end-stage kidney disease population. Timely, sensitive and individualised Advance Care Planning discussions are acceptable and beneficial for people with end-stage kidney disease and can help foster realistic hopes and goals. To explore the experiences of people with end-stage kidney disease regarding starting haemodialysis, its impact on quality of life and their preferences for future care and to explore the Advance Care Planning needs of this population and the timing of this support. Semi-structured qualitative interview study of people receiving haemodialysis. Interviews were analysed using thematic analysis. Recruitment ceased once data saturation was achieved. A total of 20 patients at two UK National Health Service hospitals, purposively sampled by age, time on haemodialysis and symptom burden. Themes emerged around: Looking Back, emotions of commencing haemodialysis; Current Experiences, illness and treatment burdens; and Looking Ahead, facing the realities. Challenges throughout the trajectory included getting information, communicating with staff and the 'conveyor belt' culture of haemodialysis units. Participants reported a lack of opportunity to discuss their future, particularly if their health deteriorated, and variable involvement in treatment decisions. However, discussion of these sensitive issues was more acceptable to some than others. Renal patients have considerable unmet Advance Care Planning needs. There is a need to normalise discussions about preferences and priorities in renal and haemodialysis units earlier in the disease trajectory. However, an individualised approach is essential - one size does not fit all. © The Author(s) 2014.

    Full Text Available Grass pollen, in particular from Lolium multiflorum is a major allergen source in temperate climate zones of Southern Brazil. The IgE sensitization profile of Brazilian grass pollen allergic patients to individual allergen molecules has not been analyzed yet.To analyze the IgE sensitization profile of a Brazilian grass pollen allergic population using individual allergen molecules.We analyzed sera from 78 grass pollen allergic patients for the presence of IgE antibodies specific for 103 purified micro-arrayed natural and recombinant allergens by chip technology. IgE-ELISA inhibition experiments with Lolium multiflorum, Phleum pratense extracts and a recombinant fusion protein consisting of Phl p 1, Phl p 2, Phl p 5 and Phl p 6 were performed to investigate cross-reactivities.Within the Brazilian grass pollen allergic patients, the most frequently recognized allergens were Phl p 1 (95%, Phl p 5 (82%, Phl p 2 (76% followed by Phl p 4 (64%, Phl p 6 (45%, Phl p 11 (18% and Phl p 12 (18%. Most patients were sensitized only to grass pollen allergens but not to allergens from other sources. A high degree of IgE cross-reactivity between Phleum pratense, Lolium multiflorum and the recombinant timothy grass fusion protein was found.Component-resolved analysis of sera from Brazilian grass pollen allergic patients reveals an IgE recognition profile compatible with a typical Pooideae sensitization. The high degree of cross-reactivity between Phleum pratense and Lolium multiflorum allergens suggests that diagnosis and immunotherapy can be achieved with timothy grass pollen allergens in the studied population.

    and prevention of ulcers and amputations of lower limbs. Material and methods: Transversal descriptive observational study. Carried out with 51 patients included in the haemodialysis programme of the Unit in Segovia. Analyses were carried out of the different risk factors that influence the presence of arteriopathy and diabetic foot, and the different relationships between them as well as a stratification of the risk in the population studied. Results: 45% of the patients present peripheral arterial disease and 58% have sensitivity alterations. Diabetes firstly and cardiovascular diseases are the factors that have the most influence in these problems. Conclusions: Categorizing our patients according to risk will make it possible to plan strategies to prevent the appearance of these complications. The absence of previous examination shows inadequate monitoring. The high prevalence of these pathologies makes protocolized monitoring necessary.

    Full Text Available ABSTRACT: CONTEXT AND OBJECTIVE: Personal resilience is associated with several mental health outcomes. The Connor-Davidson resilience scale (CD-RISC is a widely used self-report measurement of resilience. This study aimed to investigate the reliability and validity of a Brazilian Portuguese version of the CD-RISC. DESIGN AND SETTING: Cross-sectional validation study carried out in the outpatient clinics of a public university hospital. METHODS: The cross-cultural adaptation followed established guidelines and involved interviews with 65 adults in psychiatric and non-psychiatric outpatient clinics at a teaching hospital. Validation was assessed through concurrent application of the Lipp Brazilian Stress Symptom Inventory (ISSL, Self-Report Questionnaire (SRQ, Sheehan Disability Scales (SDS and Chronic Pain Grade (CPG to 575 patients at the same setting. Temporal stability was verified through a second application to 123 participants. RESULTS: Factor analysis identified four factors, named tenacity, adaptability-tolerance, reliance on support from outside and intuition. The alpha coefficient of 0.93 and intraclass correlation coefficient of 0.84 indicated good internal consistency and temporal stability. Significant correlations between this version of the CD-RISC and the ISSL, SRQ, SDS and CPG were noted. The patients at the outpatient clinic for borderline personality had resilience scores that were significantly lower than those of the patients at the general anxiety or post-traumatic stress outpatient clinics. CONCLUSION: This Brazilian Portuguese version of the Connor-Davidson resilience scale exhibited adequate reliability and validity among a sample of Brazilian adult patients.

    Full Text Available OBJECTIVE: To evaluate the effectiveness of the Brazilian Cardioprotective Diet Program in reducing blood pressures, fasting glucose levels and body mass indices in patients with established atherothrombotic disease. METHOD: This randomized controlled pilot trial included outpatients who were over 45 years of age with atherothrombotic cardiovascular disease. Group A, who received the Brazilian Cardioprotective Diet Program, had weekly sessions with dietitians. Groups B and C received the usual dietary therapy that is given to patients with cardiovascular diseases as proposed by the Brazilian guidelines. This diet had the same nutrient profile as that given to Group A, but it was customized by the integration of typical Mediterranean foods. The difference between Groups B and C was the number of sessions with the dietitian. Group B received weekly sessions, while group C only had monthly sessions. ClinicalTrials.gov: NCT 01453166. RESULTS: There was a greater reduction in systolic (7.8% and diastolic (10.8% blood pressures in Group A compared with Group B (2.3% and 7.3%, and Group C (3.9% and 4.9%, respectively. Fasting glucose decreased by 5.3% and 2% in Groups A and B, respectively. Fasting glucose increased by 3.7% in Group C. The BMIs decreased by 3.5% and 3.3% in Groups A and B, respectively. Group C did not present with any changes in BMI. However, none of these data showed statistical differences between the groups, which is methodologically acceptable in pilot trials. CONCLUSIONS: The Brazilian Cardioprotective Diet Program seems to be more effective in reducing blood pressures, fasting glucose levels, weights and BMIs in patients with previous cardiovascular disease compared with the diet that has been proposed by the Brazilian guidelines.

    Full Text Available Background/Aim: The effect of hypertension on mortality in haemodialysis patients is controversial and can be confounded by non-traditional risk factors like systemic inflammation. This study examined the effect of systolic blood pressure (SBP, diastolic blood pressure (DBP, and pulse pressure (PP on mortality in haemodialysis patients, separately with and without markers of systemic inflammation. Methods:Data from the United States Renal Data System were analysed for 9,862 patients receiving haemodialysis on December 31, 1993, followed through May 2005. Results: In Cox regression analysis, increased age, diabetes, low albumin, high white blood count, low cholesterol, low haemoglobin, high phosphate, low DBP, and cardiovascular comorbidity were associated with high mortality, but SBP was not. Elevated PP adjusted for SBP, age, diabetes, haemoglobin, albumin, cholesterol, calcium, phosphate, parathyroid hormone, and white blood count was associated with higher mortality [adjusted hazard ratio, PP 1.006 (95% confidence interval, CI, 1.002–1.010; SBP 0.993 (95% CI 0.990–0.996]. In dual models, PP adjusted for SBP then DBP was associated with higher mortality [PP 1.029 (95% CI 1.027–1.032; SBP 0.981 (95% CI 0.979–0.983; PP 1.010 (95% CI 1.008–1.011; DBP 0.981 (95% CI 0.979–0.983]. Increasing PP deciles >70 mm Hg were associated with increasing mortality in the absence of markers of systemic inflammation (white blood count >10 × 109/l, albumin Conclusion: PP was a better indicator of adverse outcome than DBP or SBP. Inflammation-associated injury may mask the effect of PP on mortality in haemodialysis patients.

    During haemodialysis procedure, the contact of blood with the membrane material contained in the hemodialyser results in protein deposition and adsorption, and surface-adsorbed proteins may trigger a variety of biological pathways with potential pathophysiologic consequences. The present work was undertaken to examine for protein adsorption capacity of two membranes used for clinical haemodialysis, namely cellulose triacetate (a derivatized cellulosic membrane) and the synthetic polymer polysulfone-based helixone. We performed a prospective cross-over study in chronic haemodialysis patients, routinely treated with a cellulose triacetate dialyser (n=3) or with a helixone dialyser (n=3). Dialysers from each patient were obtained after dialysis session, and flushed with a litre of saline to remove residual blood. Adsorbed proteins were then eluted by a strong chaotropic buffer. Patients were next switched to the other membrane dialyser for four weeks, at the end of this period protein adsorption being evaluated again. After silver staining, expression profile protein of the two groups was analyzed by 2-DE gels, analyzed and identified by Peptide Mass-finger printing and MALDI-TOF-MS/MS sequency. Moreover nanoLC-MS/MS shotgun profiling was pursued using a semi-quantitative label free approach by emPAI data analysis. A total of 54 differentially expressed proteins were identified: 22 proteins more concentrated in helixone membrane (predominantly low abundant plasma proteins) and 32 in cellulose triacetate (most represented by high abundant plasma proteins). The difference proved to be related to membrane material and not to patient's characteristics. Proteomic techniques represent a useful approach for the investigation of proteins surface-adsorbed onto a haemodialysis membrane, and can also be applied for critical assessment to compare efficiencies of different dialyser membrane materials in the adsorption of plasma proteins.

    Full Text Available OBJECTIVE: To assess the impact of multiple sclerosis (MS on the professional life of Brazilian patients. METHOD: One hundred MS patients were randomly selected from the database of the Brazilian Multiple Sclerosis Association (ABEM. An individual interview was carried out by telephone by a member of ABEM, who collected data on the patients' clinical status, educational level and professional lives. RESULTS: Complete data were obtained from 96 patients (27 males and 69 females aged 55.0±14.1 years, with average disease duration of 4.6±4.0 years. Eighty percent had eleven or more years of schooling. Among the whole group, 66% did not present limitations on walking. The longer the disease duration and the older the patient were, the higher the chances were that the patient was retired or receiving workers' compensation benefits. However, even among patients with MS for less than five years, the rate of non-participation in the workforce was 47.7%. Fatigue, paresthesia, cognitive dysfunction and pain were often cited as the motives for not working. CONCLUSION: MS patients presented high levels of unemployment, retirement and receipt of workers' compensation benefits, despite their high schooling levels. Age, disease duration and disability influenced these results for the whole group. However, even among younger patients with shorter disease duration and low disability, this finding remained.

    The present study was designed to clarify the structure of culture and the three components of attitude in a desirable attitude toward dietary management actions in outpatient haemodialysis patients who are in the maintenance phase of treatment. The participants in the study included nine patients undergoing chronic maintenance haemodialysis who have received guidance related to diet and had good test results. Ethnography, by means of participant observation and semi-structured interviews, was chosen as the research method. Desirable attitude of haemodialysis patients in dietary management actions was found to have a chronological progression in one of the components of attitude: propensity of behaviour. Change in behaviour was influenced by affect and cognition. At the base of the structure of attitude lay three factors: valuing cooking with seasonal ingredients and creating special meals for seasonal occasions; family draws near, shows care and gives support; and belief in information perceived to be good for the health, which was influenced by three components of attitude: affect, cognition, and propensity of behaviour, as well as culture. Participants continue to value the food culture that they grew up with, which involves their affect towards, and cognition of, dietary management. © 2013 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Patients with celiac disease (CD) can develop a gluten related autoimmune disorder that affects not only the small intestine but other tissues as well. An increased prevalence of autoimmune diseases has been reported, particularly autoimmune thyroiditis. The aim of this study was to characterize thyroid disorders in patients with CD. Fifty-two patients with CD (43 female, 9 male; mean age, 41.1 years) were studied. Nine were on a gluten-free diet (GFD). They were divided into four groups: Group 1, without thyroid involvement (n=30); Groups 2A-C, with thyroid involvement (n=22); Group 2A, subclinical hypothyroidism (n=11); Group 2B, clinical hypothyroidism (n=10); and Group 2C, other thyroid disorders (n=1). CD was confirmed by serologic and histologic criteria. Thyroid involvement was detected by measurement of thyroid stimulating hormone (TSH) and anti-thyroperoxidase antibodies (anti-TPO). Increased levels of TSH and/or anti-TPO levels were detected in Groups 2A (21.1%) and 2B (19.2%). The patients of Group 2B presented clinical symptoms of hypothyroidism before the diagnosis of CD, and 5 of these patients were receiving levothyroxine. One woman (Group 2C; 1.92%) had a medullary carcinoma. There was statistical significance between the age when thyroid disease was diagnosed (current age) and the age of CD diagnosis between Groups 1 and 2B. Patients with thyroid involvement presented associated diseases such as diabetes mellitus (2), Down's syndrome (2), ulcerative colitis (1), and dermatitis herpetiformis (2). Our findings demonstrated an increased prevalence of thyroid disorders (hypothyroidism, 19.2%; and subclinical hypothyroidism, 21.2%), and other associated diseases in celiac patients, even on a GFD, increasing with the age of the patients. Screening for associated diseases is recommended for patients with CD, independent of age at diagnosis or treatment duration.

    Full Text Available Introduction Published data suggest that patients with acromegaly have an increased prevalence of prostate disorders. Objective To evaluate prostatic disorders in acromegalic patients comparing these results after one year of treatment of acromegaly and with a group of healthy men. Materials and Methods This study was composed of two parts: sectional study comparing patients with healthy controls (baseline and prospective, longitudinal study (at baseline and after one year of treatment. Forty acromegalic patients were enrolled and evaluated at baseline and after one year with the application of international prostatic symptoms score (IPSS, digital rectal examination, measurements of growth hormone (GH, insulin-like growth factor-I (IGF-I, insulin-like growth factor-binding protein-3 (IGFBP-3, sex hormone-binding globulin (SHBG, prolactin, luteinizing hormone (LH, follicle-stimulating hormone (FSH, total testosterone, total and free prostate-specific antigen (PSA levels and prostate ultrasonography (US. Thirty healthy men were selected as control group. Results We stratified patients and controls according to age, considering 40 years-old as cut off. Healthy controls under 40 had IPSS values lower than acromegalic patients. When considering only older patients and controls prostate hyperplasia and structural abnormalities were more frequent in acromegalics. After one year of treatment there was significant decrease in GH, IGF-I and prostate volume in acromegalics over 40 years-old. Conclusions Acromegalics under 40 have more urinary symptoms according to IPSS and above 40 years-old higher frequency of structural changes and increased prostate volume than healthy men. Significant reduction of GH and IGF-I levels during treatment of acromegaly leads to decrease in the prostate volume.

    Phenylketonuria (PKU) is characterized by phenylalanine (Phe) accumulation to toxic levels due to the low activity of phenylalanine-hydroxylase. PKU patients must follow a Phe-restricted diet, which may put them in risk of nutritional disturbances. Therefore, we aimed to characterize body composition parameters and nutritional status in Brazilian PKU patients also considering their metabolic control. Twenty-seven treated PKU patients older than 5 years, and 27 age- and gender-matched controls, were analyzed for anthropometric features and body composition by bioelectrical impedance (BIA). Patients' metabolic control was assessed by historical Phe levels. There was no effect of PKU type, time of diagnosis, or metabolic control for any analyzed parameter. About 75% of patients and controls were eutrophic, according to their BMI values. There were no difference between groups regarding body composition and other BIA-derived parameters. Brazilian PKU patients do not show differences in body composition and nutritional status in comparison with controls, regardless metabolic control. Although similar to controls, PKU patients may be in risk of disturbed nutritional and metabolic markers as seen for the general population.

    Although hospitalization is recognized as an important cause of reduction in physical activity in daily life (PADL) in COPD, there is only one study evaluating this effect, and it was performed in European COPD patients who have a lower PADL than that of South American COPD patients. To investigate the effect of hospitalization due to acute exacerbation of PADL in Brazilian COPD patients and to evaluate the factors that determines the physical activity levels during hospitalization and after discharge. PADL was quantified using a 3-axis accelerometer on the 3rd day of hospitalization and 1 month after discharge in Brazilian COPD patients who were hospitalized due to disease exacerbation. Six-minute walking distance (6MWD), lower limb strength and pulmonary function were also evaluated. A total of 20 patients completed the study. During hospitalization, patients spent most of the time (87%) lying down or sitting; however, 1 month after they were walking >40 min/day. In addition, patients with prior hospitalization had a lower level of physical activity compared to those without a previous history of hospitalization. The time spent walking during hospitalization was significantly explained by the quadriceps strength (r(2) = 0.29; p active 1 month after discharge. Previously hospitalized are more inactive both during and after exacerbation. The quadriceps strength and 6MWD explain the physical activity levels during hospitalization and at home, respectively.

    Malnutrition is common in patients undergoing haemodialysis (HD). Several studies have described different nutritional parameters as mortality predictors but few have studied whether there are differences between genders. This study aimed to evaluate which nutrition parameters may be associated with mortality in patients undergoing long-term HD depending on their gender. Longitudinal prospective multicentre study with 12 months of follow-up. Anthropometric and laboratory measures were obtained from 697 patients. Men who died were older, had lower dry weight, body mass index, potassium, phosphorus and albumin, compared with male patients who survived. Female patients who died had lower albumin and nPCR compared with survivors. Kaplan-Meier analysis displayed a significantly worse survival in patients with albumin genders and with body mass index genders. Associations between albumin, body mass index and mortality risk continued to be significant after adjustments for age, length of time on dialysis and diabetes for males. However, in women, only albumin persisted as an independent predictor of death. Depending on the gender, different parameters such as protein intake, potassium, phosphorus, body mass index and albumin are associated with mortality in patients undergoing HD. Albumin genders, whereas a body mass index <23 kg/m(2) is an independent predictor of death, but only in men. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    1999-01-01

    Full Text Available Moyamoya disease (MMD is a chronic occlusive cerebrovascular disease of unknown etiology reported mainly in the Japanese. Most cases occur in children. The disease is rare in non-Oriental adults manifesting itself mostly as intracerebral hemorrhages. We describe MMD in 2 non-Oriental young adults and one adolescent that developed cerebral infarctions. The adults were medicated with aspirin and no medication was given to the adolescent. All patients did not deteriorate in a follow-up period from 1 to 4 years. Although rare, MMD is an important cause of stroke in young individuals and may well be underreported: only 18 patients have been reported till 1997 in Brazil. Neurologists should include MMD in differential diagnosis of ischemic and hemorrhagic strokes in young adults.

    Full Text Available Background. Haemodialysis (HD catheter-related bloodstream infections (CRBSIs are a major complication of long-term catheter use in HD. This study identified the epidemiology of HD CRBSIs and to aid in the choice of empiric antibiotics therapy given to patients with HD CRBSIs. Methods. Patients with HD CRBSIs were identified. Their blood cultures were performed according to standard sterile technique. Specimens were sent to the microbiology lab for culture and sensitivity testing. Results were tabulated in antibiograms. Results. 18 patients with a median age of 61.0 years (IQR: 51.5–73.25 were confirmed to have HD CRBSIs based on our study criteria. Eight (44.4% patients had gram-negative infections, 7 (38.9% patients gram-positive infections, and 3 (16.7% patients had polymicrobial infections. We noted that most of the gram-negative bacteria were sensitive to ceftazidime. Unfortunately, cloxacillin resistance was high among gram-positive organisms. Coagulase-negative Staphylococcus and Bacillus sp. were the most common gram-positive organisms and they were sensitive to vancomycin. Conclusion. Our study revealed the increased incidence of gram-negative organism in HD CRBSIs. Antibiogram is an important tool in deciding empirical antibiotics for HD CRBSIs. Tailoring your antibiotics accordingly to the antibiogram can increase the chance of successful treatment and prevent the emergence of bacterial resistance.

    The purpose of this pilot study was to explore whether individualized Reiki given to cancer patients at a Brazilian hospital improved symptoms and well-being. Data from 36 patients who received 5 Reiki sessions were collected using the MYMOP and were compared before and after their treatment and also with 14 patients who did not receive Reiki and who acted as a comparison group. Twenty-one patients reported feeling better, 12 felt worse, and 3 reported no change. Of the comparison group, 6 patients reported feeling better and 8 felt worse. The Reiki practice delivered as part of the integrative care in oncology did produce clinically significant effects, although not statistically significant results, for more than half of the patients undergoing cancer treatment.

    Mycetoma is a chronic subcutaneous mycosis caused by exogenous fungi or actinomycetes. This infection has a progressive course and shows a typical clinical characteristic of tumefaction, draining sinuses, and grains. Infection initiation is related to local trauma and can spread to muscle, underlying bone, and adjacent organs. Nocardia brasiliensis is the most frequent actinomycete isolated, while N. caviae is a rare agent. We present a case of mycetoma in a 37-year-old African-American man on the right hand. The infection had been apparent for four years prior to the consultation. When the infection did not respond to antibiotic therapy, the patient was referred to the Dermatology department. Routine laboratory studies were normal. X-ray examination of the hand showed an osteolytic lesion on the hand bones. On skin biopsy culture, on Sabouraud Dextrose Agar at 28 degrees C, a colony was isolated which was further identified as N. caviae by biochemical and hydrolysis testing. The patient was treated with oral trimethoprim/sulfamethoxazole (TMP/SMZ) 160/800 mg twice a day for 10 months. Four months after the beginning of the therapy, the subject exhibited clinical improvement and functional recovery of the hand. Five-year follow-up X-ray examination of the hand showed no osteolytic lesion on the hand bones. We report the first mycetoma case caused by N. caviae in our country with an unusual location on the hand. The patient showed clinical improvement with oral TMP/SMZ.

    To present the translation and cross-cultural adaptation of the Brazilian version of the Northwestern Dysphagia Patient Check Sheet (NDPCS). The translation to Portuguese was performed by two Brazilian bilingual speech language pathologists, followed by a back translation conducted by a bilingual native speaker of the original language. Afterwards, the three versions were compared by a committee of three speech language pathologists. Initially, the final translated version of the NDPCS was applied with 35 volunteers aged between 62 and 92 years old (74.77±7.08), who had no dementia or complaints of swallowing disorder. After some adjustments, the instrument was applied with other 27 volunteers aged between 60 and 87 years old (76.56±7.07) with the same profile. There was divergence in semantic equivalence in relation to one item, which was modified in the translated version. The tasks requested for observation during deglutition were adapted in relation to the solid food and the volumes used in pudding and liquid consistencies. The instrument maintained the same structure as the original version, with five categories and into 28 items, three brief variables, and four closures. The equivalence between the original and the translated version of the NDPCS was preserved after its translation and adaptation to Brazilian Portuguese. The validation process of the psychometric properties of the instrument is in progress.

    The environmental impact of haemodialysis is very high. Institutional activity in this sense is important, even in the production of references. Voluntary environmental management systems (EMS), environmental management and auditing systems (EMAS) and the International Organization for Standardization standards (ISO 14001) are important tools for environmental protection, together with legislation, taxation and tax benefits. To determine the degree of implementation of EMS in hospital units and outpatient haemodialysis in the Spanish National Health System to provide a group of reference centres in environmental management in this healthcare activity. Development of a list by autonomous communities showing hospital and outpatient dialysis units using an EMAS and/or ISO 14001 in 2012-2013. The sources of information were the Spanish National Catalogue of Hospitals, Spanish Registry of Healthcare Certification and Accreditation, European and regional EMAS records, world ISO registrations, dialysis centre lists from scientific societies and patients, responses from accredited entities in Spain for environmental certification and the institutional website of each haemodialysis centre identified. Of the 210 hospitals with a dialysis unit, 53 (25%) have the ISO 14001 and 15 of these also have an EMAS). This constitutes 30% of all hospital dialysis chairs in Spain: 1,291 (of 4,298). Only 11 outpatient clinics are recorded, all with the ISO 14001. There is no official documentation of the implementation of EMS in dialysis units. Making this list provides an approach to the situation, with special reference to haemodialysis because of its significant environmental impact. Copyright © 2015 Sociedad Española de Nefrología.

    Nelson Hamerschlak

    Full Text Available CONTEXT AND OBJECTIVES: Chronic myeloid leukemia (CML requires strict daily compliance with oral medication and regular blood and bone marrow control tests. The objective was to evaluate CML patients' perceptions about the disease, their access to information regarding the diagnosis, monitoring and treatment, adverse effects and associations of these variables with patients' demographics, region and healthcare access. DESIGN AND SETTING: Prospective cross-sectional study among CML patients registered with the Brazilian Lymphoma and Leukemia Association (ABRALE. METHODS: CML patients receiving treatment through the public healthcare system were interviewed by telephone. RESULTS: Among 1,102 patients interviewed, the symptoms most frequently leading them to seek medical care were weakness or fatigue. One third were diagnosed by means of routine tests. The time that elapsed between first symptoms and seeking medical care was 42.28 ± 154.21 days. Most patients had been tested at least once for Philadelphia chromosome, but 43.2% did not know the results. 64.8% had had polymerase chain reaction testing for the BCR/ABL gene every three months. 47% believed that CML could be controlled, but 33.1% believed that there was no treatment. About 24% reported occasionally stopping their medication. Imatinib was associated with nausea, cramps and muscle pain. Self-reported treatment adherence was significantly associated with normalized blood count, and positively associated with imatinib. CONCLUSIONS: There is a lack of information or understanding about disease monitoring tools among Brazilian CML patients; they are diagnosed quickly and have good access to treatment. Correct comprehension of CML control tools is impaired in Brazilian patients.

    Full Text Available INTRODUCTION: Many patients with multiple sclerosis (MS are currently receiving treatment with interferon beta (IFNb and glatiramer acetate (GA. Identifying nonresponders patients is important to define therapy strategies. Several criteria for treatment response to IFNb and GA have been proposed. OBJECTIVE: It was to investigate the response to treatment with IFNb-1a, IFNb-1b and GA among relapsing-remitting multiple sclerosis (RRMS patients. METHODS: We analyzed treatment response to IFNb and GA in ninety-one RRMS patients followed for at least one year. Clinical response was established by clinical criteria based on relapses, disability progression or both. RESULTS: We observed a proportion of nonresponders, ranging from 3.3 to 42.9%, depending on the stringency of the criteria used. CONCLUSIONS: Our sample of Brazilian patients with MS has similarities when compared to other studies and there was no statistically significant difference regarding age, gender, ethnicity or disease duration between responders and nonresponders.

    Full Text Available ABSTRACT Background International studies have demonstrated an increase in the prevalence of boys and a decrease of patients’ age at the beginning of outpatient treatment for eating disorders (ED. Objective To evaluate if these changes are also present in the Brazilian population participating in the PROTAD, a Brazilian ED program, and to discuss its clinical implication for treatment. Methods Cross-sectional study. We evaluated 150 medical records of patients under 18 years diagnosed with ED (DSM IV-TR. Patients were divided into two groups: G1 (2001-2007 (n = 77 and G2 (2008-2014 (n = 73. The girl/boy proportion and the mean age of patients were compared. Results In G1, six boys (7.8% were admitted (girl/boy proportion: 11.8:1, while in G2, 16 (22% boys were admitted (girl/boy proportion: 3.5:1 (p 0.05. Discussion The increase in the number of boys treated for EDs reported in international studies was also found at the PROTAD. Contrary to what has been reported in international studies, the mean age of patients at the PROTAD did not decrease significantly. Gender and sexual orientation issues, clinical presentation, prior overweight history and culture/media impact on boys should be addressed by the healthcare team to increase the therapeutic efficacy.

    Full Text Available This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living and IADL (instrumental activities of daily living. Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

    Full Text Available Background/Aims: Hepatitis C virus infection remains prevalent among patients undergoing long-term haemodialysis and has a detrimental impact on survival in this population. Antiviral therapy for chronic hepatitis C in haemodialysis patients is still a challenge to clinicians. The aim of the current study is to evaluate the efficacy and safety of therapy with pegylated interferon, alone or combined with ribavirin, for chronic hepatitis C among patients undergoing long-term hemodialysis. Methods: We conducted a retrospective, multicenter cohort trial with monotherapy (pegylated interferon (n=21 or combined antiviral therapy (pegylated interferon plus ribavirin (n=5 for chronic hepatitis C in patients undergoing long-term haemodialysis. Results: Sustained virological response was obtained in eleven (42% patients. Seven (26.9% patients interrupted prematurely the antiviral treatment due to serious side-effects, the most frequent cause of treatment withdrawal being hematological (n=3. HCV RNA load was lower in responder than non-responder patients, 5.44 (3.45; 6.36 vs. 5.86 (4.61; 6.46 log10 copies/mL, even if the difference was not significant (P=0.099. Blood transfusion requirement was greater in patients on combined antiviral therapy than those on pegylated interferon alone, 100% (5/5 vs. 0% (0/21, P=0.0001. No difference in sustained viral response occurred between patients on combined antiviral therapy and those on pegylated interferon monotherapy [40% (2/5 vs. 42.8% (9/21, P=0.90]. Conclusions: Results from this study showed that pegylated interferon alone or with ribavirin is unsatisfactory in terms of efficacy and safety. Prospective trials based on interferon-free regimens (i.e., sofosbuvir plus ribavirin or sofosbuvir plus daclatasvir are under way in patients with hepatitis C receiving long-term hemodialysis.

    Leprosy is a chronic disease caused by infection with Mycobacterium leprae, an obligate intracellular parasite. A problem in studying the transmission of leprosy is the small amount of variation in bacterial genomic DNA. The discovery of variable number of tandem repeats (VNTRs) allowed the detection of strain variation in areas with a high prevalence of leprosy. Four genotypes of M. leprae based on three single-nucleotide polymorphism (SNPs) were also discovered to be useful for analysis of the global spread of leprosy. In this present study, we examined the allelic diversity of M. leprae at 16 select VNTR and three SNP loci using 89 clinical isolates obtained from patients mainly from the neighbouring states of São Paulo and Rio de Janeiro Brazil. By use of a PCR-RFLP-based procedure that allows the recognition of SNP types 3 and 4 without the need for the more expensive DNA sequencing steps, characterisation of the main M. leprae genotypes was easy. When applied on the study population, it was found that the SNP type 3 is most frequent in these two states of Brazil, and that VNTRs provided further discrimination of the isolates. Two Short Tandem Repeats (STRs) were monomorphic, with the remaining 14 STRs represented by two to 18 alleles. Epidemiological associations with township or state were not evident in this random collection and require further investigations. In phylogenetic trees, branches formed by all 16 STRs clearly separated SNP type 3 organisms from the other types while the allelic patterns of two minisatellite loci 27-5 and 12-5 were highly correlated with SNP type 3. This strain typing study provide the basis for comparison of M. leprae strain types within Brazil and with those from other countries, and informed selection of genomic markers and methods for future studies.

    Independent validation of the Non motor Symptoms Scale in Parkinson's disease (NMSS) based on a cross-culturally adapted Brazilian version. Parkinson's disease (PD) patients were evaluated by means of the Scales for Outcomes in Parkinson's disease-Motor (SCOPA-M), Autonomic, Cognition, and Psychosis; Hoehn and Yahr staging (H&Y); Berg Balance Scale; PD Sleep Scale; Clinical Impression of Severity Index for PD (CISI-PD); PDQ-39; and EQ-5D. The following clinimetric attributes were explored for the NMSS: acceptability, scaling assumptions, reliability, construct validity, and precision. 150 patients were assessed (mean age 63.1 years; 56.7% males; mean duration of illness 8.7 years; HY median: 2). Mean NMSS was 48.9 (SD 36.3; median 42; skewness 1.3). Neither floor nor ceiling effect was observed on the NMSS total score. For domains, the Cronbach's alpha coefficient ranged from 0.40 to 0.82. The NMSS total score correlated significantly with SCOPA-AUT (r(S) = 0.65) and with those scales measuring related constructs (r(S) = 0.46-0.57). NMSS significantly increased as the H&Y stage increased (Kruskal-Wallis, p < 0.0001). These values were quite close to those from the original validation studies. The NMSS is a reliable and valid measure to evaluate non motor symptoms in Brazilian PD patients. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available OBJECTIVE: Show the steps of a Trauma Registry (TR implementation in a Brazilian public hospital and evaluate the initial data from the database.METHODS: Descriptive study of the a TR implementation in João XXIII Hospital (Hospital Foundation of the state of Minas Gerais and analysis of the initial results of the first 1,000 patients.RESULTS: The project was initiated in 2011 and from January 2013 we began collecting data for the TR. In January 2014 the registration of the first 1000 patients was completed. The greatest difficulties in the TR implementation were obtaining funds to finance the project and the lack of information within the medical records. The variables with the lowest completion percentage on the physiological conditions were: pulse, blood pressure, respiratory rate and Glasgow coma scale. Consequently, the Revised Trauma Score (RTS could be calculated in only 31% of cases and the TRISS methodology applied to 30.3% of patients. The main epidemiological characteristics showed a predominance of young male victims (84.7% and the importance of aggression as a cause of injuries in our environment (47.5%, surpassing traffic accidents. The average length of stay was 6 days, and mortality 13.7%.CONCLUSION: Trauma registries are invaluable tools in improving the care of trauma victims. It is necessary to improve the quality of data recorded in medical records. The involvement of public authorities is critical for the successful implementation and maintenance of trauma registries in Brazilian hospitals.

The variables with the lowest completion percentage on the physiological conditions were: pulse, blood pressure, respiratory rate and Glasgow coma scale. Consequently, the Revised Trauma Score (RTS) could be calculated in only 31% of cases and the TRISS methodology applied to 30.3% of patients. The main epidemiological characteristics showed a predominance of young male victims (84.7%) and the importance of aggression as a cause of injuries in our environment (47.5%), surpassing traffic accidents. The average length of stay was 6 days, and mortality 13.7%. Trauma registries are invaluable tools in improving the care of trauma victims. It is necessary to improve the quality of data recorded in medical records. The involvement of public authorities is critical for the successful implementation and maintenance of trauma registries in Brazilian hospitals.

    Full Text Available INTRODUCTION: Rheumatoid arthritis (RA is a commonly occurring systemic inflammatory auto immune disease and is believed to be associated with genetic factors. The innate immune complement protein Mannose binding lectin (MBL and their MBL2 genetic variants are associated with different infectious and autoimmune diseases. METHODS: In a Brazilian cohort, we aim to associate the functional role of circulating MBL serum levels and MBL2 variants in clinically classified patients (n = 196 with rheumatoid arthritis including their relatives (n = 200 and ethnicity matched healthy controls (n = 200. MBL serum levels were measured by ELISA and functional MBL2 variants were genotyped by direct sequencing. RESULTS: The exon1+54 MBL2*B variant was significantly associated with an increased risk and the reconstructed haplotype MBL2*LYPB was associated with RA susceptibility. Circulating serum MBL levels were observed significantly lower in RA patients compared to their relatives and controls. No significant contribution of MBL levels were observed with respect to functional class, age at disease onset, disease duration and/or other clinical parameters such as nodules, secondary Sjögren syndrome, anti-CCP and rheumatoid factor. Differential distribution of serum MBL levels with functional MBL2 variants was observed in respective RA patients and their relatives. CONCLUSIONS: Our results suggest MBL levels as a possible marker for RA susceptibility in a Brazilian population.

    Patients with chronic kidney disease often use religion as a coping strategy to relieve suffering and serve as a source of strength. The aim of this study was to identify religious aspects associated with mental health and quality of life in Brazilian dialysis patients. A cross-sectional study was performed involving two dialysis centers in Brazil. Patients were selected consecutively over three typical dialysis treatment days. The questionnaire was self-administered and covered the following aspects: socio-demographic aspects, religiousness (using the Portuguese version of the Private and Social Religious Practice Scale), quality of life (World Health Organization Quality of Life brief Scale Brief Version), depression and anxiety (Beck Inventory), and pain grade. For statistical analysis, the hypothesis that different religious variables are associated (positively or negatively) with depressive/anxiety symptoms and quality of life in these patients was tested using linear regression, controlling for confounding variables. A total of 205 patients were invited to participate and 133 (64.8%) agreed to fill out the questionnaire. On the adjusted model, reading religious literature was found to be inversely associated with depressive symptoms (P quality of life was positively associated with an increase in patient religiosity (P = 0.030) and greater religious importance for recovery from their dialysis condition (P = 0.016), whereas the environmental domain was positively associated with greater religious importance for recovery (P = 0.032). No religious aspects were associated with anxiety symptoms. Religiousness is associated with less depressive symptoms and better quality of life in Brazilian dialysis patients. Nephrologists should evaluate the patient's spirituality and religion in order to provide more integrative care.

    Full Text Available Fanconi anemia is a rare hereditary disease showing genetic heterogeneity due to a variety of mutations in genes involved in DNA repair pathways, which may lead to different clinical manifestations. Phenotypic variability makes diagnosis difficult based only on clinical manifestations, therefore laboratory tests are necessary. New advances in molecular pathogenesis of this disease led researchers to develop a diagnostic test based on Western blot for FANCD2. The objective of the present study was to determine the efficacy of this method for the diagnosis of 84 Brazilian patients with Fanconi anemia, all of whom tested positive for the diepoxybutane test, and 98 healthy controls. The FANCD2 monoubiquitinated isoform (FANCDS+/FANCD2L- was not detected in 77 patients (91.7%. In 2 patients (2.4%, there was an absence of both the monoubiquitinated and the non-ubiquitinated proteins (FANCD2S-/FANCD2L- and 5 patients (5.9% had both isoforms (FANCD2S+/FANCD2L+. This last phenotype suggests downstream subtypes or mosaicism. All controls were diepoxybutane negative and were also negative on the FANCD2 Western blot. The Western blot for FANCD2 presented a sensitivity of 94% (79/84 and specificity of 100% (98/98. This method was confirmed as an efficient approach to screen Brazilian patients with deleterious mutations on FANCD2 (FANCD2S-/FANCD2L- or other upstream genes of the FA/BRCA pathway (FANCDS+/FANCD2L-, to confirm the chromosome breakage test and to classify patients according to the level of FA/BRCA pathway defects. However, patients showing both FANCD2 isoforms (FANCD2S+/FANCD2L+ require additional studies to confirm mutations on downstream Fanconi anemia genes or the presence of mosaicism.

    We present the case of a 39 year-old male patient admitted to ICU with symptoms of acute metabolic acidosis. He was investigated for the presence of methanol and glycol. Conservative treatment was initially started, followed by haemodialysis. During insertion of a temporary haemodialysis catheter in a location of Haapaniemi and Slatis, the patient was conscious but restless; therefore sedation was required to continue the procedure. After three hours of haemodialysis, the patient's general condition suddenly deteriorated. Hypovolemic shock and acute respiratory distress led to hypothesis of right haemothorax, which was rapidly confirmed by angio-CT examination. Trachea was intubated, drainage of right pleura was performed and aggressive fluid treatment begun. The patient was admitted to the operating theatre, and thoracotomy with reconstruction of damaged right venous angle was carried out. After the operation, the patient was transferred to ICU. He was mechanically ventilated and remained haemodynamically unstable. Although fluids and blood-made concentrates were transfused and catecholamines continuously administered, his clinical condition deteriorated and finally the patient died. We found two independent causes of this fatality: hypovolemic shock and acute extrinsic metabolic acidosis. However, this paper focuses on the problem of the iatrogenic complication, which was haemothorax. In the literature there are described examples of such cases. Authors emphasise the most traumatic moment of cannulation as being insertion of the guidewire and dilator to perform a tunnel for the catheter. Puncture by needle and localisation of the central vein results in fewer complications. Furthermore, we strongly recommend monitoring patients after central veins cannulation. All sudden deteriorations in clinical condition should be followed by meticulous diagnosis for the presence of this life-threatening complication.

    Background Appetite and symptoms, conditions generally reported by the patients with cancer, are somewhat challenging for professionals to measure directly in clinical routine (latent conditions). Therefore, specific instruments are required for this purpose. This study aimed to perform a cultural adaptation of the Cancer Appetite and Symptom Questionnaire (CASQ), into Portuguese and evaluate its psychometric properties on a sample of Brazilian cancer patients. Methods This is a validation study with Brazilian cancer patients. The face, content, and construct (factorial and convergent) validities of the Cancer Appetite and Symptom Questionnaire, the study tool, were estimated. Further, a confirmatory factor analysis (CFA) was conducted. The ratio of chi-square and degrees of freedom (χ2/df), comparative fit index (CFI), goodness of fit index (GFI) and root mean square error of approximation (RMSEA) were used for fit model assessment. In addition, the reliability of the instrument was estimated using the composite reliability (CR) and Cronbach’s alpha coefficient (α), and the invariance of the model in independent samples was estimated by a multigroup analysis (Δχ2). Results Participants included 1,140 cancer patients with a mean age of 53.95 (SD = 13.25) years; 61.3% were women. After the CFA of the original CASQ structure, 2 items with inadequate factor weights were removed. Four correlations between errors were included to provide adequate fit to the sample (χ2/df = 8.532, CFI = .94, GFI = .95, and RMSEA = .08). The model exhibited a low convergent validity (AVE = .32). The reliability was adequate (CR = .82 α = .82). The refined model showed strong invariance in two independent samples (Δχ2: λ: p = .855; i: p = .824; Res: p = .390). A weak stability was obtained between patients undergoing chemotherapy and radiotherapy (Δχ2: λ: p = .155; i: p < .001; Res: p < .001), and between patients undergoing chemotherapy combined with radiotherapy and

    Full Text Available ABSTRACT Introduction: Multiple factors negatively affect the quality of life of patients infected with hepatitis C virus. This study aims to evaluate the effect of pharmacological treatment on the quality of life of these individuals. Methods: This is a cross-sectional study conducted in two Southern Brazilian centers that used two instruments (a generic and a specific one for measuring the quality of life in patients with chronic hepatitis C: the Short Form-36 (SF-36; and the Chronic Liver Disease Questionnaire (CLDQ for liver disease. We included patients from two centers without any treatment (control group, or receiving medication (peginterferon + ribavirin ± telaprevir or boceprevir, i.e., respectively, dual, and triple therapies. Results: One hundred and forty-seven patients were included. Patients under treatment (n = 86 had a lower score in 7 of the 8 SF-36 domains, with statistical significance (p<0.05 only for the emotional function domain. Patients who were not treated (n = 58 had higher scores in 4 of the 6 (p<0.05 CLDQ domains. A comparison of patients, receiving dual or triple therapies for both questionnaires, was only significant in the Vitality domain from CLDQ. Conclusions: Treatment can affect the subjective perception of patients regarding quality of life. Due to the complexity of the disease, each patient must be evaluated in multiple dimensions. Thus, the results may be useful for understanding the patient's perceptions during treatment, and it can also serve as a reference for care instructions.

    Full Text Available Abstract Background Chronic Kidney Disease is a major public health problem worldwide with enormous cost burdens on health care systems in developing countries. We aimed to provide a detailed analysis of the processes and costs of haemodialysis in Sri Lanka and provide a framework for modeling similar financial audits. Methods This prospective study was conducted at haemodialysis units of three public and two private hospitals in Sri Lanka for two months in June and July 2010. Cost of drugs and consumables for the three public hospitals were obtained from the price list issued by the Medical Supplies Division of the Department of Health Services, while for the two private hospitals they were obtained from financial departments of the respective hospitals. Staff wages were obtained from the hospital chief accountant/chief financial officers. The cost of electricity and water per month was calculated directly with the assistance of expert engineers. An apportion was done from the total hospital costs of administration, cleaning services, security, waste disposal and, laundry and sterilization for each unit. Results The total number of dialysis sessions (hours at the five hospitals for June and July were 3341 (12959 and 3386 (13301 respectively. Drug and consumables costs accounted for 70.4-84.9% of the total costs, followed by the wages of the nursing staff at each unit (7.8-19.7%. The mean cost of a dialysis session in Sri Lanka was LKR 6,377 (US$ 56. The annual cost of haemodialysis for a patient with chronic renal failure undergoing 2-3 dialysis session of four hours duration per week was LKR 663,208-994,812 (US$ 5,869-8,804. At one hospital where facilities are available for the re-use of dialyzers (although not done during study period the cost of consumables would have come down from LKR 5,940,705 to LKR 3,368,785 (43% reduction if the method was adopted, reducing costs of haemodialysis per hour from LKR 1,327 at present to LKR 892 (33

    Hypertrophic cardiomyopathy (HC) is the most prevalent genetic cardiac disease caused by a mutation in sarcomeres, Z-disks, or calcium-handling genes and is characterized by unexplained left ventricular hypertrophy. The aim of this study was to determine the genetic profile of Brazilian patients with HC and correlate the genotype with the phenotype. We included 268 index patients from São Paulo city and 3 other cities in Brazil and extracted their DNA from whole blood. We amplified the coding sequencing of MYH7, MYBPC3, and TNNT2 genes and sequenced them with an automatic sequencer. We identified causal mutations in 131 patients (48.8%). Seventy-eight (59.5%) were in the MYH7 gene, 50 (38.2%) in the MYBPC3 gene, and 3 (2.3%) in the TNNT2 gene. We identified 69 mutations, 24 not previously described. Patients with an identified mutation were younger at diagnosis and at current age, had a higher mean heart rate and higher nonsustained ventricular tachycardia frequency compared with those without a mutation. Patients with MYH7 gene mutations had a larger left atrium and higher frequency of atrial fibrillation than did patients with MYBPC3 gene mutations. The presence of a mutation in one of the genes suggests a worse prognosis. Mutations in the MYH7 gene, rather than in the MYBPC3 gene, were also related to a worse prognosis. This is the first work characterizing HC molecular epidemiology in the Brazilian population for the 3 most important genes. © 2013.

Data were collected with a questionnaire that included the EuroQol 5 Dimensions (EQ-5D) instrument. Patients from the five regions of Brazil were interviewed. Multiple linear regression was used to analyze their Health-Related Quality of Life and its associated factors. Of the total of 8,590 patients, the most frequent dimensions were pain/discomfort (50.7%) and anxiety/depression (38.8%). About 10% of the patients reported extreme problems in these dimensions. The following factors were significantly associated with a worse quality of life: being female; having arthritis, osteoarthritis, or rheumatism; cerebrovascular accident; heart disease; depression; health self-assessment as poor or very poor; drinking alcoholic beverages once or more per month; dieting to lose weight, avoiding salt consumption, and reducing fat intake. Significant association was observed between a better quality of life and: living in the North and Southeast regions of Brazil; practicing physical activities; and having a higher educational level. No association was observed with factors related to the health services. The Health-Related Quality of Life of patients was influenced by demographic and socioeconomic factors that were related to health conditions and lifestyle, being useful to guide specific actions for promoting health and the integral care to patients of the Brazilian Unified Health System.

    As renal replacement therapy has become universal practice in medicine, there is a need to consider whether this treatment is suitable for elderly people. These patients have high comorbidity and may require dialysis withdrawal in certain clinical circumstances. Advance directives (ADs) drawn up by patients facilitate treatment-related decisions if they lose cognitive capacity. Questionnaires dealing with possible extreme clinical circumstances can thus help clinicians and relatives reach pertinent decisions in such cases. We studied the usefulness of questionnaires on ADs in patients who started periodic haemodialysis over a period of 10 years. Telephone interviews were conducted to assess satisfaction level among relatives/representatives of deceased patients who had been advised to limit therapeutic efforts in certain clinical situations. The questionnaire was assessed using a six-factor degree of satisfaction. Four hundred and forty-three questionnaires were distributed over a period of 10 years. A total of 41.3% of patients stated that they wished to limit therapeutic efforts in the serious clinical situations presented; 37.9% refused to complete the questionnaire; 14.7% expressed their wishes without any written confirmation; and 6.1% expressed their wish to continue on dialysis in all situations. Two hundred and twenty-four patients had died by the study end date. The cause of death in 20.2% was scheduled dialysis withdrawal. Representatives reported an extremely high degree of satisfaction with the questionnaire (94.7%). Younger people, however, were more reluctant to consider and answer questionnaires on ADs. Questionnaires on ADs are a useful tool in daily nephrology practice and should be distributed to those patients willing to consider the limitation of therapeutic efforts in extreme clinical circumstances. In general terms, these questionnaires should be given to all elderly patients.

    Full Text Available BACKGROUND: Approximately one-half of Brazilian patients with hereditary hemochromatosis (HH are neither homozygous for the C282Y mutation nor compound heterozygous for the H63D and C282Y mutations that are associated with HH in Caucasians. Other mutations have been described in the HFE gene as well as in genes involved in iron metabolism, such as transferrin receptor 2 (TfR2 and ferroportin 1 (SCL40A1. AIMS: To evaluate the role of HFE, TfR2 and SCL40A1 mutations in Brazilian subjects with HH. PATIENTS AND METHODS: Nineteen male subjects (median age 42 [range: 20-72] years with HH were evaluated using the Haemochromatosis StripAssay A®. This assay is capable of detecting twelve HFE mutations, which are V53M, V59M, H63D, H63H, S65C, Q127H, P160delC, E168Q, E168X, W169X, C282Y and Q283, four TfR2 mutations, which are E60X, M172K, Y250X, AVAQ594-597del, and two SCL40A1 mutations, which are N144H and V162del. RESULTS: In our cohort, nine (47% patients were homozygous for the C282Y mutation, two (11% were heterozygous for the H63D mutation, and one each (5% was either heterozygous for C282Y or compound heterozygous for C282Y and H63D. No other mutations in the HFE, TfR2 or SCL40A1 genes were observed in the studied patients. CONCLUSIONS: One-third of Brazilian subjects with the classical phenotype of HH do not carry HFE or other mutations that are currently associated with the disease in Caucasians. This observation suggests a role for other yet unknown mutations in the aforementioned genes or in other genes involved in iron homeostasis in the pathogenesis of HH in Brazil.

    Full Text Available Purpose: To assess the sociodemographic profiles, teratogen exposures, and ocular congenital abnormalities in Brazilian patients with Möbius sequence. Method: Forty-four patients were recruited from the Brazilian Möbius Sequence Society. This cross-section comprised 41 patients (age, mean ± standard deviation, 9.0 ± 5.5 years who fulfilled the inclusion criteria. The parent or caregiver answered a questionnaire regarding sociodemographic data and pregnancy history. Patients underwent ophthalmological assessments. They were subdivided into groups according to misoprostol exposure during pregnancy, and the two groups were compared. Results: Mothers/caregivers reported unplanned pregnancies in 36 (88% cases. Of these, 19 (53% used misoprostol during their first trimesters. A stable marital status tended to be more frequent in the unexposed group (P=0.051. Incomplete elementary school education was reported by two (11% mothers in the exposed group and by three (14% mothers in the unexposed group (P=0.538. The mothers' gestational exposures to cocaine, marijuana, alcohol, and cigarettes were similar in both groups (P=0.297, P=0.297, P=0.428, and P=0.444, respectively. One (5% case of Rubella infection during pregnancy was found in the unexposed group. The main malformations in the exposed and unexposed groups were the following: strabismus (72% and 77%, respectively, lack of emotional tearing (47% and 36%, respectively, and lagophthalmos (32% and 41%, respectively. Conclusion: Stable marital statuses tended to be more frequent among mothers that did not take misoprostol during pregnancy. Exposures to other teratogens and the main ocular abnormalities were similar in both groups.

    Lung cancer is the leading global cause of cancer-related mortality and is associated with poor prognosis. To improve survival rates of lung cancer patients, better understanding of tumorigenic mechanisms is necessary, which may lead to development of new therapeutic strategies. The hOGG1 and NTH1 genes act in the DNA BER repair pathway and their involvement in lung cancer pathogenesis has been analyzed in several populations. We analyzed targeted regions of the hOGG1 and NTH1 genes in 96 Brazilian patients with non-small-cell lung cancer (NSCLC) and 89 cancer-free, ethnically matched controls. The NTH1 c.98G>T polymorphism rs2302172 (p = 0.02 and p = 0.02 for allele and genotype frequency between cases and controls, respectively) and the 140-17C> T variant (rs2233518) (p = 0.02 and p = 0.02 for allele and genotype frequency between cases and controls, respectively) were detected in four lung cancer cases (4 %) while the NTH1 Q131K (C391A) polymorphism was found in seven lung cancer cases (7 %) (p = 0.001 and p = 0.008, for allele and genotype frequency between cases and controls, respectively). None of these sequence variants were detected in controls. The Ser326Cys (C1245G, rs1052133) polymorphism in the OGG1 gene was detected in 42 % of analyzed NSCLC patients and in 34 % of the controls (p = 0.11 and p = 0.25 for allele and genotype frequency between cases and controls, respectively). Our study provides preliminary evidence that polymorphisms in OGG1 do not contribute to development of NSCLC in Brazilian patients and that NTH1 polymorphisms may be associated with NSCLC pathogenesis.

    To evaluate the psychometric properties of the Multidimensional Pain Inventory (MPI) in a Brazilian sample of patients with orofacial pain. A total of 1,925 adult patients, who sought dental care in the School of Dentistry of São Paulo State University's Araraquara campus, were invited to participate; 62.5% (n=1,203) agreed to participate. Of these, 436 presented with orofacial pain and were included. The mean age was 39.9 (SD=13.6) years and 74.5% were female. Confirmatory factor analysis was conducted using χ²/df, comparative fit index, goodness of fit index, and root mean square error of approximation as indices of goodness of fit. Convergent validity was estimated by the average variance extracted and composite reliability, and internal consistency by Cronbach's alpha standardized coefficient (α). The stability of the models was tested in independent samples (test and validation; dental pain and orofacial pain). The factorial invariance was estimated by multigroup analysis (Δχ²). Factorial, convergent validity, and internal consistency were adequate in all three parts of the MPI. To achieve this adequate fit for Part 1, item 15 needed to be deleted (λ=0.13). Discriminant validity was compromised between the factors "activities outside the home" and "social activities" of Part 3 of the MPI in the total sample, validation sample, and in patients with dental pain and with orofacial pain. A strong invariance between different subsamples from the three parts of the MPI was detected. The MPI produced valid, reliable, and stable data for pain assessment among Brazilian patients with orofacial pain.

    Bloom syndrome is a rare, autosomal recessive, chromosomal instability disorder caused by mutations in the BLM gene that increase the risk of developing neoplasias, particularly lymphomas and leukemias, at an early age. Case 1 was a 10-year-old Brazilian girl, the third child of a non-consanguineous non-Jewish family, who was born at 36 weeks of gestation and presented with severe intrauterine growth restriction. She had Bloom syndrome and was diagnosed with a unilateral Wilms' tumor at the age of 3.5 years. She responded well to oncological treatment and has remained disease-free for the last 17 years. Case 2 was a 2-year-old Brazilian girl born to non-Jewish first-degree cousins. Her gestation was marked by intrauterine growth restriction. She had Bloom syndrome; a unilateral stage II Wilms' tumor was diagnosed at the age of 4 years after the evaluation of a sudden onset abdominal mass. Surgical removal, neoadjuvant chemotherapy and radiotherapy were not sufficient to control the neoplasia. The tumor recurred after 8 months and she died from clinical complications. Our study reports the importance of rapid diagnostics and clinical follow-up of these patients.

    Full Text Available The aim of this study was to measure the caries prevalence in the root surface in a group of Brazilian adults. The prevalence and their intraoral distribution of caries lesions of root surface were assessed in dental patients ranging in age from 35 to 44 and from 50 to 59 years of age of both sexes (n=360. A total of 98.9% had root surfaces with gingival recession and 78.1% had at least one root caries lesion. The prevalence of the disease was analyzed using the Root Caries Index (RCI. The average value was greater for women (18.6% than for men (13.4% (p0.01. The maxillary canines and first premolars and the mandibular molars presented the greatest RCI values. The RCI was greater in the proximal surface of the maxilla and buccal surface of the mandible. We conclude that caries of the root surface are present in the Brazilian population and deserve attention concerning their actual role in the epidemiology of principal oral diseases of the adult population.

    Full Text Available ContextGastroparesis is defined by delayed gastric emptying without mechanical obstruction of the gastroduodenal junction, which has been increasingly investigated. Nevertheless, knowledge on the relationships between etiology, symptoms and degree of delayed gastric emptying is limited.ObjectivesThe demographic, clinical and etiological features of Brazilian patients with gastroparesis were studied and the relationships between these findings and the severity of gastric emptying were determined.MethodThis is a retrospective study of medical records of 41 patients with symptoms suggestive of gastroparesis admitted between 1998 and 2011, who had evidence of abnormally delayed gastric emptying on abdominal scintigraphy. Cases with idiopathic gastroparesis were compared with those of patients with neurologic disorders or diabetes mellitus, in whom autonomic neuropathy is likely to occur.ResultsThe majority of the patients were women (75.6% with a median age of 41 years and a long-term condition (median: 15 years. Twelve patients (29.3% had a body mass index of less than 20 kg/m2. The most common presenting symptoms were dyspepsia (53.6%, nausea and vomiting (46.3%, weight loss (41.4% and abdominal pain (24.3%. Regarding etiology, 16 patients had digestive disorders including idiopathic gastroparesis (n = 12, 12 had postoperative conditions, 11 had diseases of the nervous system, five had diabetes mellitus and in three cases gastroparesis was associated to a variety of conditions. In the majority of patients (65.8% gastric emptying was severely delayed. There was no association between etiology of gastroparesis, type of presenting symptoms and the degree of delay in gastric emptying. Gastroparesis patients with proven (neurological conditions or presumed (diabetes nervous system involvements were significantly younger (P= 0.001, had more recent symptom onset (P= 0:03 and a trend towards more severe gastric empty (P = 0:06. There were no significant

    This paper describes the development of a haemodialysis error taxonomy system for analysing incidents and predicting the safety status of a dialysis organisation. The error taxonomy system was developed by adapting an error taxonomy system which assumed no specific specialty to haemodialysis situations. Its application was conducted with 1,909 incident reports collected from two dialysis facilities in Japan. Over 70% of haemodialysis incidents were reported as problems or complications related to dialyser, circuit, medication and setting of dialysis condition. Approximately 70% of errors took place immediately before and after the four hours of haemodialysis therapy. Error types most frequently made in the dialysis unit were omission and qualitative errors. Failures or complications classified to staff human factors, communication, task and organisational factors were found in most dialysis incidents. Device/equipment/materials, medicine and clinical documents were most likely to be involved in errors. Haemodialysis nurses were involved in more incidents related to medicine and documents, whereas dialysis technologists made more errors with device/equipment/materials. This error taxonomy system is able to investigate incidents and adverse events occurring in the dialysis setting but is also able to estimate safety-related status of an organisation, such as reporting culture. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

  11. Bovine and porcine heparins: different drugs with similar effects on human haemodialysis

    Science.gov (United States)

    2013-01-01

    Background Heparins from porcine and bovine intestinal mucosa differ in their structure and also in their effects on coagulation, thrombosis and bleeding. However, they are used as undistinguishable drugs. Methods We compared bovine and porcine intestinal heparin administered to patients undergoing a particular protocol of haemodialysis. We compared plasma concentrations of these two drugs and also evaluated how they affect patients and the dialyzer used. Results Compared with porcine heparin, bovine heparin achieved only 76% of the maximum plasma concentration as IU mL-1. This observation is consistent with the activities observed in the respective pharmaceutical preparations. When the plasma concentrations were expressed on weight basis, bovine heparin achieved a maximum concentration 1.5 fold higher than porcine heparin. The reduced anticoagulant activity and higher concentration, on weight basis, achieved in the plasma of patients under dialysis using bovine instead of porcine heparin did not affect significantly the patients or the dialyzer used. The heparin dose is still in a range, which confers security and safety to the patients. Discussion Despite no apparent difference between bovine and porcine intestinal heparins in the haemodialysis practice, these two types of heparins should be used as distinct drugs due to their differences in structure and biological effects. Conclusions The reduced anticoagulant activity achieved in the plasma of patients under dialysis using bovine instead of porcine heparin did not affect significantly the patients or the dialyzer.

    Merosin-deficient congenital muscular dystrophy (CMD) is characterized clinically by hypotonia and muscular weakness and, on imaging studies, by white matter (WM) abnormality. To evaluate MRI findings in Brazilian patients with merosin-deficient CMD. Twenty-five patients were evaluated using MRI. Three patients presented with partial merosin deficiency and 22 with total merosin deficiency. Follow-up examinations were done in 7 cases. T1- and T2-weighted images were performed in all examinations, and fluid-attenuated inversion recovery (FLAIR) was performed in 15. Enhanced images were done in 11 cases. The WM involvement was classified according to location and severity. From 1991 to 2004, 32 MRI examinations were performed. Severe involvement was found in 23 patients in the frontal and temporal lobes, in 18 patients in the parietal lobes, and in 7 patients in the occipital lobes. The brain stem (n=5), cerebellum (n=6), internal capsules (n=1), and external capsules (n=5) were also affected. One patient had occipital pachygyria, and one had cerebellar vermian hypoplasia. No gadolinium enhancement was noted. Follow-up MRI showed no interval change (n=4), progression (n=1), or improvement of the findings (n=2). (orig.)

    Currently, there is no questionnaire to assess perceived stigmatization among people with visible differences in Brazil. The Perceived Stigmatization Questionnaire (PSQ), developed in the United States, is a valid instrument to assess the perception of stigmatizing behaviours among burn survivors. The objective of this cross-sectional and multicentre study was to assess the factor structure, reliability and validity of the Brazilian Portuguese version of the PSQ in burn patients. A Brazilian version of the 21-item PSQ was answered by 240 adult burn patients, undergoing rehabilitation in two burns units in Brazil. We tested its construct validity by correlating PSQ scores with depression (Beck Depression Index-BDI) and self-esteem (Rosenberg Self-Esteem Scale-RSE), as well as with two domains of the Revised Burn Specific Health Scale-BSHS-R: affect and body image, and interpersonal relationships. We used Confirmatory Item Factor Analysis (CIFA) to test whether the data fit a measurement model involving a three-factor structure (absence of friendly behaviour; confusing/staring behaviour; and hostile behaviour). We conducted Exploratory Factor Analyses (EFA) of the subscale in a 50% random sample of individuals (training split), treating items as ordinal categorical using unweighted least squares estimation. To assess discriminant validity of the Brazilian version of the PSQ we correlated PSQ scores with known groups (sex, total body surface area burned, and visibility of the scars) and assessed its reliability by means of Cronbach's alpha and using test-retest. Goodness-of-fit indices for confirmatory factor analysis were satisfactory for the PSQ, but not for the hostile behaviour subscale, which was modified to improve fit by eliminating 3 items. Cronbach's alphas for the PSQ refined version (PSQ-R) ranged from 0.65 to 0.88, with test-retest reliability 0.87 for the total score. The PSQ-R scores correlated strongly with depression (0.63; p < 0.001), self-esteem (-0

    To describe the clinical and angiographic characteristics of Takayasu's arteritis in Brazilian children and adolescents. A retrospective data collection was performed in 71 children and adolescents followed in 10 Brazilian reference centers in Pediatric Rheumatology. The evaluation was carried out in three different time points: from onset of symptoms to diagnosis, from the 6th to 12th month of diagnosis, and in the last visit. Of 71 selected patients, 51 (71.8%) were girls. The mean age of onset of symptoms and of time to diagnosis was 9.2 (±4.2) years and 1.2 (±1.4) years, respectively. At the end of the study, 20 patients were in a state of disease activity, 39 in remission and 5 had evolved to death. The most common symptoms in baseline assessment, second evaluation, and final evaluation were, respectively: constitutional, musculoskeletal, and neurological symptoms. A decrease in peripheral pulses was the most frequent cardiovascular signal, and an increase in erythrocyte sedimentation rate was the most frequent laboratory finding in all three evaluation periods. The tuberculin test was positive in 41% of those tested. Stenosis was the most frequent angiographic lesion, abdominal artery was the most affected segment, and angiographic type IV the most frequent. Most (90%) participants were treated with glucocorticoids, 85.9% required another immunosuppressive drug, and 29.6% underwent angioplasty. This is the largest study on juvenile-onset Takayasu arteritis, and a high number of patients under the age of 10 years, with predominance of constitutional symptoms early in the disease, was observed.

    Full Text Available PURPOSE: To examine the prevalence of ocular surface complaints in Brazilian patients with glaucoma or ocular hypertension who used topical intraocular pressure (IOP-lowering regimens. METHODS: In this multicenter, noninterventional, single-visit study, adults with glaucoma or ocular hypertension treated with an IOP-lowering regimen were administered the 12-item ocular surface disease index (OSDI questionnaire. Each response was scored on a 5-point scale, with 0 indicating symptom present none of the time and 4 indicating symptom present all of the time. The average of the 12 item responses for each patient was transformed to a scale from 0 to 100, with higher scores representing worse disabilities. OSDI results then were categorized as absence of OSD (scores of 0-12, mild OSD (scores of 13-22, moderate OSD (scores of 23-32, or severe OSD (scores of 33100. RESULTS: The 173 enrolled patients had a mean age of 61.2 years, were women in 65.3% of cases, and had glaucoma in 89.0% of cases and ocular hypertension in 11.0% of cases. OSDI scores for 158 patients using 1 IOP-lowering therapy indicated no OSD in 37.3% of patients (59/158, mild OSD in 20.9% (33/158, moderate OSD in 17.1% (27/158, and severe OSD in 24.7% (39/158. For the 120 patients using 1 IOP-lowering medication and having a known duration of diagnosis of glaucoma or ocular hypertension, mean OSDI scores were numerically higher (worse for the 39 patients with a diagnosis ≥6 years long (score 25 [± 20], indicating moderate OSD than for the 81 patients with a diagnosis lasting <6 years (score 22 [± 20], indicating mild OSD; however, no significant differences in OSDI scores by duration of diagnosis were evident in means (P=0.49, distributions (P≥0.26, or correlation (P=0.77. CONCLUSIONS: A large proportion of Brazilian patients treated with 1 IOP-lowering therapy had some ocular surface complaints.

    Full Text Available Estimates of occult hepatitis B virus (HBV infection prevalence varies among different studies depending on the prevalence of HBV infection in the study population and on the sensitivity of the assay used to detect HBV DNA. We investigated the prevalence of occult HBV infection in cirrhotic patients undergoing liver transplantation in a Brazilian referral center. Frozen liver samples from 68 adults were analyzed using a nested polymerase chain reaction assay for HBV DNA. The specificity of the amplified HBV sequences was confirmed by direct sequencing of the amplicons. The patient population comprised 49 (72.1% males and 19 (27.9% females with a median age of 53 years (range=18-67 years. Occult HBV infection was diagnosed in three (4.4% patients. The etiologies of the underlying chronic liver disease in these cases were alcohol abuse, HBV infection, and cryptogenic cirrhosis. Two of the patients with cryptic HBV infection also presented hepatocellular carcinoma. Markers of previous HBV infection were available in two patients with occult HBV infection and were negative in both. In conclusion, using a sensitive nested polymerase chain reaction assay to detect HBV DNA in frozen liver tissue, we found a low prevalence of occult HBV infection in cirrhotic patients undergoing liver transplant, probably due to the low prevalence of HBV infection in our population.

    Hepatitis C virus (HCV) infection is the most common blood-borne viral infection in haemodialysis. It causes significant morbidity and long-term mortality. Practice of universal precautions has been reported to be sufficient to prevent HCV seroconversion in dialysis units. However, the seroconversion rate remains very high in many dialysis units. A previous study from 1995 to 1998 at our own hospital without isolation showed that nosocomial transmission is the major cause of HCV seroconversion. The present study was therefore conducted with the aim to study the impact of isolation on HCV seroconversion. In this prospective cohort study, with non-probability consecutive sampling, patients with HCV infection were dialysed in an isolated room. In addition, standard universal precautions were practiced. HCV seroconversion rate was compared with the previous study. All patients with end-stage kidney disease (ESKD) admitted to our hospital for renal replacement therapy were included in the present study. At the time of admission, HCV screening was done. All anti-HCV-positive patients were dialysed in an isolated room. While on maintenance haemodialysis, all patients were monthly tested for anti-HCV, aspartate aminotransferase and alanine aminotransferase. Any patient who had HCV seroconversion was transferred to an isolated room for maintenance haemodialysis. Patients with HCV infection were managed by further testing for HCV-RNA and liver biopsy. Every patient who ultimately received renal transplantation at our hospital was also tested for HCV just prior to renal transplantation as well as 3 months after renal transplantation. HCV infection was diagnosed by detecting anti-HCV antibodies using an ELISA-based third-generation diagnostic test kit. Serum bilirubin, aspartate aminotransferase and alanine aminotransferase were assayed using standard laboratory techniques. From March 2003 to February 2006, 1,417 patients were admitted for haemodialysis in our unit. Of these 1

    Prader-Willi Syndrome is a common etiology of syndromic obesity that is typically caused by either a paternal microdeletion of a region in chromosome 15 (microdeletions) or a maternal uniparental disomy of this chromosome. The purpose of this study was to describe the most significant clinical features of 35 Brazilian patients with molecularly confirmed Prader-Willi syndrome and to determine the effects of growth hormone treatment on clinical outcomes. A retrospective study was performed based on the medical records of a cohort of 35 patients diagnosed with Prader-Willi syndrome. The main clinical characteristics were compared between the group of patients presenting with microdeletions and the group presenting with maternal uniparental disomy of chromosome 15. Curves for height/length, weight and body mass index were constructed and compared between Prader-Willi syndrome patients treated with and without growth hormone to determine how growth hormone treatment affected body composition. The curves for these patient groups were also compared with curves for the normal population. No significant differences were identified between patients with microdeletions and patients with maternal uniparental disomy for any of the clinical parameters measured. Growth hormone treatment considerably improved the control of weight gain and body mass index for female patients but had no effect on either parameter in male patients. Growth hormone treatment did not affect height/length in either gender. The prevalence rates of several clinical features in this study are in agreement with the rates reported in the literature. Additionally, we found modest benefits of growth hormone treatment but failed to demonstrate differences between patients with microdeletions and those with maternal uniparental disomy. The control of weight gain in patients with Prader-Willi syndrome is complex and does not depend exclusively on growth hormone treatment.

    BACKGROUND: If blood pressure (BP) falls during haemodialysis (HD) [intradialytic hypotension (IDH)] a common clinical practice is to reduce the extracorporeal blood flow rate (EBFR). Consequently the efficacy of the HD (Kt/V) is reduced. However, only very limited knowledge on the effect......L/min diastolic BP, mean arterial pressure, PR and CO remained unchanged. CONCLUSION: Our study does not show any consistent trend in BP changes by a reduction in EBFR. Reduction in EBFR if BP falls during IDH is thus not supported. However, none of the patients experienced IDH. Further studies are required...... to evaluate the impact of changes in EBFR on BP during IDH....

    Full Text Available Bioimpedance analysis has been widely used to estimate a hydration state, lean and fat mass in haemodialysis patients. The aim of our study was to investigate the validity and usefulness of bioimpedance analysis in routine dialysis practice. Last two years we used the body composition monitoring (BCM, Fresenius Medical Care, method based on whole body multifrequency bioimpedance spectroscopy (BIS, compared with traditional clinical data. For BIS data verification, hydration status of 32 stable HD patients with dialysis vintage more than 3 years and clinically well established dry weight were studied. Only in three cases BIS data seems underestimated in serial measurements. Next step, 28 healthy subjects and 116 dialysis patients were studied. Total body water and extracellular volume (ECV were significantly higher in dialysis group (P<0.01, and there was not any difference in intracellular volume (ICV. Mean AP was similar in patients with moderate (<15% and massive (>15% relative overhydration (RO = overhydration / ECV, at the same time, average number of antihypertensive medications was significantly higher in more overhydrated patients (3.1 vs 1.2. In clinical practice RO is more convenient indicator as compared to standard overhydration volume /dry weight ratio. Mutual application of the BIS and blood volume monitoring allows more rapid and safe dry weight achievement. BIS was useful tool for hydration status monitoring in routine haemodialysis practice, and further work need to be done to clarify BIS validity for nutritional status estimation.

    Full Text Available The aim of the study was to analyze a series of Brazilian patients with Niemann-Pick disease type C (NP-C. Method Correlations between clinical findings, laboratory data, molecular findings and treatment response are presented. Result The sample consisted of 5 patients aged 8 to 26 years. Vertical supranuclear gaze palsy, cerebellar ataxia, dementia, dystonia and dysarthria were present in all cases. Filipin staining showed the “classical” pattern in two patients and a “variant” pattern in three patients. Molecular analysis found mutations in the NPC1 gene in all alleles. Miglustat treatment was administered to 4 patients. Conclusion Although filipin staining should be used to confirm the diagnosis, bone marrow sea-blue histiocytes often help to diagnosis of NP-C. The p.P1007A mutation seems to be correlated with the “variant” pattern in filipin staining. Miglustat treatment response seems to be correlated with the age at disease onset and disability scale score at diagnosis.

    The Fatigue Severity Scale (FSS) is one of the most frequently used self-rating scales for fatigue in Parkinson's disease (PD) and it lacks a validated Brazilian-Portuguese version. To determine the construct validity and reproducibility of a Brazilian-Portuguese version of the FSS in patients with PD. In a cross-sectional study, a Portuguese-language version of the FSS was applied to 30 patients with PD (62±11 years-old). The Parkinson's disease questionnaire (PDQ-39) was used as the validation criterion, while the Hoehn and Yahr scale, the Unified Parkinson's Disease Rating Scale (UPDRS), and the Beck Depression Inventory were employed to analyze the correlations with the FSS score. The test-retest intraclass correlation coefficient was 0.91 (pHoehn and Yahr scale (r=0.40; p=0.02), and with the UPDRS as well (r=0.45, p=0.01). The Brazilian-Portuguese version of the FSS is valid and reproducible for using in Brazilian patients with PD.

    To improve the short-form Mini-Nutritional Assessment (MNA) to ameliorate under-rating the risk of malnutrition in patients on haemodialysis. The full MNA was found to be appropriate for rating the risk of malnutrition in persons undergoing haemodialysis but the short-form under-rated the risk. A cross-sectional study with purposive sampling. The study recruited 152 adult ambulatory patients on maintenance haemodialysis from one dialysis centre in Taiwan. Each subject was rated with the Subjective Global Assessment (SGA), the original and selected alternative short-forms (by replacing better performing nonshort-form items for lesser performing short-form items) of a Taiwanese-specific MNA (T1). Serum albumin and creatinine concentrations and the SGA were also used as referents. Results were evaluated with Pearson's correlation analysis, binary classification test and receiver operating characteristic (ROC) curves. The full MNA showed good consistency with the SGA, but the original short-form rated fewer patients at risk of malnutrition compared with the full MNA. Exchanging item O (self-rated nutritional status) with item E (neuropsychological problems) produced the best results and restored the predictive ability of the short-form. Replacing item P for E produced the next best results. Results suggest that the predictive ability of the short-form can be greatly restored by rearranging the component items of the short-form without affecting the performance of the full MNA. The study is probably the first example of a disease-specific version of the MNA. The revision makes short-form MNA suitable for rating the risk of malnutrition in patients on haemodialysis in clinical practice. © 2013 John Wiley & Sons Ltd.

    We present the case of a 58-year old female with de novo dialysis-dependent acute kidney injury (AKI) secondary to myeloma cast nephropathy. The patient underwent extended high cut-off haemodialysis (HCO-HD), in conjunction with bortezomib-based chemotherapy, and soon became dialysis independent with normal renal function. To our knowledge, this is the first time this treatment strategy has been employed successfully in an Irish centre.

    Protein-energy wasting is a prevalent disorder in haemodialysis. Zinc-α2-glycoprotein (ZAG) and adipose triglyceride lipase (ATGL) are novel adipokines with recognized lipolytic effects and proposed role in metabolic homoeostasis. This study was conducted to investigate the association of ZAG and ATGL concentrations with malnutrition-inflammation score (MIS) and metabolic profile of patients with haemodialysis. Eighty-eight patients under regular haemodialysis were divided based on MIS to normal to mild wasting (NMW; n = 35) or moderate wasting (MW; n = 53) group. Anthropometric measurements along with fasting serum concentrations of ZAG, ATGL, free fatty acids (FFAs), albumin, transferrin, total iron-binding capacity (TIBC), hs-CRP, lipid profile and glucose metabolism were assessed. Adipose triglyceride lipase concentration was significantly higher in MW than NMW group (10·89 ± 5·7 vs. 8·02 ± 3·37 mIU/mL; P = 0·008). The ZAG and FFAs were not significantly different between two groups. ATGL was directly correlated with FFAs in all of the patients (r = 0·284, P = 0·007) and MW (r = 0·32, P = 0·021), and marginally in NMW (r = 0·31, P = 0·057) groups. ATGL and odds of having mild or moderate wasting were significantly correlated (OR = 1·21, P = 0·033). A positive association was observed between ATGL with TG (r = 0·31, P = 0·049) and also with transferrin and TIBC (r = 0·44, P = 0·001) only in MW group. An inverse relationship was observed between ATGL and HDL in all of the participants (r=-0·222, P = 0·04). No significant correlation was observed between ZAG and other parameters. The serum concentrations of ATGL, but not ZAG, were significantly higher in MW compared to NMW group. Each unit increase in ATGL concentrations was correlated with 21% increase in the odds of wasting severity. ATGL might play a role in wasting pathogenesis and metabolic profile in haemodialysis. © 2017 Stichting European Society

    Merosin-deficient congenital muscular dystrophy (CMD) is characterized clinically by hypotonia and muscular weakness and, on imaging studies, by white matter (WM) abnormality. To evaluate MRI findings in Brazilian patients with merosin-deficient CMD. Twenty-five patients were evaluated using MRI. Three patients presented with partial merosin deficiency and 22 with total merosin deficiency. Follow-up examinations were done in 7 cases. T1- and T2-weighted images were performed in all examinations, and fluid-attenuated inversion recovery (FLAIR) was performed in 15. Enhanced images were done in 11 cases. The WM involvement was classified according to location and severity. From 1991 to 2004, 32 MRI examinations were performed. Severe involvement was found in 23 patients in the frontal and temporal lobes, in 18 patients in the parietal lobes, and in 7 patients in the occipital lobes. The brain stem (n=5), cerebellum (n=6), internal capsules (n=1), and external capsules (n=5) were also affected. One patient had occipital pachygyria, and one had cerebellar vermian hypoplasia. No gadolinium enhancement was noted. Follow-up MRI showed no interval change (n=4), progression (n=1), or improvement of the findings (n=2). This series of patients demonstrated that there was no correlation between the extent of WM abnormality on MRI and the clinical status and degree of merosin deficiency (partial or total). Bilateral WM involvement was seen to be more prominent in the parietal, frontal, and temporal regions of the brain. The brain stem and internal and external capsules were less affected. Cerebellar WM involvement is rare. Changes on follow-up imaging studies did not correlate with the clinical status of the patient.

    The Brazilian healthcare system offers universal coverage but lacks information about how patients with PC needs are serviced by its primary care program, Estratégia Saúde da Família (ESF). Cross-sectional study in community settings. Patients in ESF program were screened using a Palliative Care Screening Tool (PCST). Included patients were assessed with Karnofsky Performance Scale (KPS), Edmonton Symptom Assessment System (ESAS) and Palliative Care Outcome Scale (POS). Patients with PC needs are accessing the ESF program regardless of there being no specific PC support provided. From 238 patients identified, 73 (43 women, 30 men) were identified as having a need for PC, and the mean age was 77.18 (95 % Confidence Interval = ±2,78) years, with non-malignant neurologic conditions, such as dementia and cerebrovascular diseases, being the most common (53 % of all patients). Chronic conditions (2 or more years) were found in 70 % of these patients, with 71 % scoring 50 or less points in the KPS. Overall symptom intensity was low, with the exception of some cases with moderate and high score, and POS average score was 14.16 points (minimum = 4; maximum = 28). Most patients received medication and professional support through the primary care units, but limitations of services were identified, including lack of home visits and limited multi-professional approaches. Patients with PC needs were identified in ESF program. Basic health care support is provided but there is a lack of attention to some specific needs. PC policies and professional training should be implemented to improve this area.

    The aim of our study was to evaluate whether convective (haemofiltration, Hf) and diffusive (haemodialysis, Hd) dialysis techniques induce different patterns of long- and short-term autonomic adjustments in haemodynamically stable dialysis patients. Ten haemodynamically stable Hd patients were studied. Each patient underwent a block of six Hd sessions, then was switched to six Hf. During the last session of each dialytic treatment, continuous beat to beat measurements of systolic arterial pressure (SAP) and heart rate (HR) were performed. Spectral analysis of heart rate variability (HRV) was made before and during the treatment to evaluate the modification of autonomic nervous system activity. Baseline values of plasma sodium, body weight, HR and SAP were not different for the two considered methods of dialysis, while the baseline values of normalized LF were significantly higher in Hf as compared to Hd and the opposite was observed for HF powers (P < 0.001). Sodium balance and body weight loss per hour did not differ between Hd and Hf while body temperature was kept constant in all sessions. Throughout the dialytic procedures, with both techniques, SAP was constant, while HR diminished from the first hour till the end of the procedure (P < 0.05). An increase in LF (and decrease in HF) was noticed only in the case of Hd, considering normalized units (P < 0.05). These selective changes were maintained also during the recovery after the procedure. The spectral analysis of RR interval variability during Hd and Hf suggests a potential autonomic advantage with Hf, to be added to the well-recognized intrinsic greater haemodynamic stability.

    Propolis contains a variety of chemical compounds, including polyphenols, flavonoids, phenolic aldehydes, amino acids and vitamins, and presents numerous biological and pharmacological properties. The aim of the present study was to evaluate the effect of propolis on blood examination data in patients with type 2 diabetes. In the double-blind, 8-week randomized controlled study, 80 patients with type 2 diabetes were enrolled. Patients were randomly assigned to receive Brazilian green propolis (226.8 mg/day for 8 weeks) (n=41) or the placebo (n=39). The primary endpoint was to detect changes in blood examination data associated with metabolic disorders in patients suffering from diabetes mellitus, including the homeostasis model assessment of insulin resistance (HOMA-IR), uric acid and estimated glomerular filtration rate (eGFR) from baseline to the end of this study. The value of HOMA-IR was not significantly changed by the 8-week administration of propolis or placebo from the baseline data. Values of blood uric acid and eGFR in patients taking the placebo became worse at 8 weeks compared to the baseline, whereas this did not occur in patients consuming Brazilian green propolis. However, HOMA-IR was not improved by propolis intake. A randomized, controlled 8-week trial suggests that Brazilian green propolis (226.8 mg/day) prevents patients with type 2 diabetes from developing worse blood uric acid and eGFR.

    The scope of the study was to evaluate patient safety culture and associated factors in Brazilian hospitals with different types of management, namely federal, state and private hospitals. The design was cross-sectional and observational. A survey of 1576 professionals at three hospitals of Rio Grande do Norte state was performed using the Hospital Survey on Patient Safety Culture adapted for Brazil, which measures 12 dimensions of safety culture. Perceptions are described by attributing a general result (Range 0-10) and the percentage of positive responses to estimate their strengths and weaknesses. The response rate was 13.6% (n= 215). The patient safety coefficient was between 7 and 10 for 78.1% of the respondents, whereby the highest average grade was attributed to the private hospital (8.32). It has been estimated that the type of hospital management, unit service, position and number of adverse event notifications are associated with the overall patient safety grade (p <0.001). Only the private hospital had strengths in the dimensions analyzed, while the weaknesses appeared in all the hospitals.

    Full Text Available Genomic DNA from 23 patients with isolated growth hormone (GH deficiency (12 males and 11 females: heights -4.9 ± 1.4 SDS was screened for GH gene deletions by restriction endonuclease analysis of polymerase chain reaction amplification products. Three unrelated patients had typical features of severe GH deficiency and deletions (6.7 kb in two and 7.6 kb in one of the GH gene. The two patients with 6.7-kb deletions developed growth-attenuating anti-GH antibodies whereas the patient with the 7.6-kb deletion continued to grow with GH replacement therapy. Our finding that 3/23 (~13% Brazilian subjects had GH gene deletions agrees with previous studies of severe isolated GH deficiency subjects in other populations. Two of three subjects (67% with deletions developed blocking antibodies despite administration of exogenous GH at low doses. Interestingly, only 1/10 of cases with affected relatives or parental consanguinity had GH-1 gene deletions

    Full Text Available OBJECTIVE: Recent evidence suggests that non-alcoholic fatty liver disease is associated with diet. Our aim was to investigate the dietary patterns of a Brazilian population with this condition and compare them with the recommended diet. METHODS: A cross-sectional study was conducted on 96 non-alcoholic fatty liver disease patients before any dietetic counseling. All patients underwent abdominal ultrasound, biochemical tests, dietary evaluations, and anthropometric evaluations. Their food intake was assessed by a semi-quantitative food-frequency questionnaire and 24-hour food recall. RESULTS: The median patient age was 53 years, and 77% of the individuals were women. Most (67.7% participants were obese, and a large waist circumference was observed in 80.2% subjects. Almost 70% of the participants had metabolic syndrome, and 62.3% presented evidence of either insulin resistance or overt diabetes. Most patients (51.5, 58.5, and 61.7%, respectively exceeded the recommendations for energy intake, as well as total and saturated fat. All patients consumed less than the amount of recommended monounsaturated fatty acids, and 52.1 and 76.6% of them consumed less polyunsaturated fatty acids and fiber, respectively, than recommended. In most patients, the calcium, sodium, potassium, pyridoxine, and vitamin C intake did not meet the recommendations, and in 10.5-15.5% of individuals, the tolerable upper limit intake for sodium was exceeded. The patients presented a significantly high intake of meats, fats, sugars, legumes (beans, and vegetables and a low consumption of cereals, fruits, and dairy products compared with the recommendations. CONCLUSIONS: Although patients with non-alcoholic fatty liver disease exhibited high energy and lipid consumption, most of them had inadequate intake of some micronutrients. The possible role of nutrient-deficient intake in the development of non-alcoholic fatty liver disease warrants investigation.

    Background Germ line mutations in BRCA1 and BRCA2 (BRCA1/2) and other susceptibility genes have been identified as genetic causes of hereditary breast and ovarian cancer (HBOC). To identify the disease-causing mutations in a cohort of 120 Brazilian women fulfilling criteria for HBOC, we carried out a comprehensive screening of BRCA1/2, TP53 R337H, CHEK2 1100delC, followed by an analysis of copy number variations in 14 additional breast cancer susceptibility genes (PTEN, ATM, NBN, RAD50, RAD51, BRIP1, PALB2, MLH1, MSH2, MSH6, TP53, CDKN2A, CDH1 and CTNNB1). Methods Capillary sequencing and multiplex ligation-dependent probe amplification (MLPA) were used for detecting point mutations and copy number variations (CNVs), respectively, for the BRCA1 and BRCA2 genes; capillary sequencing was used for point mutation for both variants TP53 R337H and CHEK2 1100delC, and finally array comparative genomic hybridization (array-CGH) was used for identifying CNVs in the 14 additional genes. Results The positive detection rate in our series was 26%. BRCA1 pathogenic mutations were found in 20 cases, including two cases with CNVs, whereas BRCA2 mutations were found in 7 cases. We also found three patients with the TP53 R337H mutation and one patient with the CHEK2 1100delC mutation. Seven (25%) pathogenic mutations in BRCA1/2 were firstly described, including a splice-site BRCA1 mutation for which pathogenicity was confirmed by the presence of an aberrant transcript showing the loss of the last 62 bp of exon 7. Microdeletions of exon 4 in ATM and exon 2 in PTEN were identified in BRCA2-mutated and BRCA1/2-negative patients, respectively. Conclusions In summary, our results showed a high frequency of BRCA1/2 mutations and a higher prevalence of BRCA1 (64.5%) gene. Moreover, the detection of the TP53 R337H variant in our series and the fact that this variant has a founder effect in our population prompted us to suggest that all female breast cancer patients with clinical criteria

    Full Text Available Spinal muscular atrophy (SMA, the second most common lethal autosomal recessive disorder, has an incidence of 1:10,000 newborns. SMA is divided into acute (Werdnig-Hoffmann disease, type I, intermediate (type II and juvenile forms (Kugelberg-Welander disease, type III. The gene of all three forms of SMA maps to chromosome 5q 11.2-13.3. Two candidate genes, the survival motor neuron (SMN gene and the neuronal apoptosis inhibitory protein (NAIP gene, have been identified; SMN is deleted in most SMA patients. We studied both genes in 87 Brazilian SMA patients (20 type I, 14 type II and 53 type III from 74 unrelated families, by using PCR and single strand conformation polymorphism (SSCP. Deletions of exons 7 and/or 8 of the SMN gene were found in 69% of the families: 16/20 in type I, 9/12 in type II and 26/42 in type III. Among 51 families with deletions, 44 had both exons deleted while seven had deletions only of exon 7. Deletions of exon 5 of the NAIP gene were found in 7/20 of type I, 2/12 of type II and 1/42 of type III patients. No deletion of SMN and NAIP genes was found in 112 parents, 26 unaffected sibs and 104 normal controls. No correlation between deletions of one or both genes and phenotype severity was found.

    2017-09-01

    Full Text Available BACKGROUND Dialysis units need regular prophylactic disinfection of the dialysis water production and distribution circuit without which there can be chronic inflammation among patients using the facility. The aim of the study is to present here our experience in containing an episode of microbial contamination of dialysis water. MATERIALS AND METHODS Our haemodialysis unit had a single pass reverse osmosis plant with facility for pretreatment of raw water and a distribution loop of medical grade PVC (polyvinyl chloride feeding haemodialysis machines, bicarbonate preparation and dialyser reprocessing areas. After installation, the Reverse Osmosis (RO membranes and distribution loop were disinfected every fortnight using formalin. Cultures of product water were sent from various sites in the product water loop every month. RESULTS From January to April 2011, 15 water samples out of 52 water samples grew Pseudomonas aeruginosa with a colony count over 200 Colony-Forming Units (CFU. The average monthly number of haemodialysis was reduced from 84.75 to 65. Two patients had intradialytic pyrexia and two others had mild lower respiratory infection. So, the reverse osmosis plant and product water distribution system were repeatedly disinfected using 2% formalin and 1% bleach ensuring contact time and thorough rinsing to address persistent cultures. When these measures could not eradicate microbial growth, the system was sanitised with Gramicid (48% w/w H2O2 + 500 ppm Ag and all traces of the disinfectant were rinsed away before resuming haemodialysis. CONCLUSION The microbial contamination of dialysis water was eradicated by Gramicid and not by bleach or formalin without any adverse effects after thorough rinsing.

    Full Text Available BACKGROUND: Nosocomial bloodstream infections (nBSIs are an important cause of morbidity and mortality and are the most frequent type of nosocomial infection in pediatric patients. METHODS: We identified the predominant pathogens and antimicrobial susceptibilities of nosocomial bloodstream isolates in pediatric patients (≤16 years of age in the Brazilian Prospective Surveillance for nBSIs at 16 hospitals from 12 June 2007 to 31 March 2010 (Br SCOPE project. RESULTS: In our study a total of 2,563 cases of nBSI were reported by hospitals participating in the Br SCOPE project. Among these, 342 clinically significant episodes of BSI were identified in pediatric patients (≤16 years of age. Ninety-six percent of BSIs were monomicrobial. Gram-negative organisms caused 49.0% of these BSIs, Gram-positive organisms caused 42.6%, and fungi caused 8.4%. The most common pathogens were Coagulase-negative staphylococci (CoNS (21.3%, Klebsiella spp. (15.7%, Staphylococcus aureus (10.6%, and Acinetobacter spp. (9.2%. The crude mortality was 21.6% (74 of 342. Forty-five percent of nBSIs occurred in a pediatric or neonatal intensive-care unit (ICU. The most frequent underlying conditions were malignancy, in 95 patients (27.8%. Among the potential factors predisposing patients to BSI, central venous catheters were the most frequent (66.4%. Methicillin resistance was detected in 37 S. aureus isolates (27.1%. Of the Klebsiella spp. isolates, 43.2% were resistant to ceftriaxone. Of the Acinetobacter spp. and Pseudomonas aeruginosa isolates, 42.9% and 21.4%, respectively, were resistant to imipenem. CONCLUSIONS: In our multicenter study, we found a high mortality and a large proportion of gram-negative bacilli with elevated levels of resistance in pediatric patients.

    Full Text Available OBJECTIVE: Although there is a considerable amount of data in the literature regarding the association between alcohol consumption and injuries treated in emergency rooms, little is known about the relationship between such injury and the use of other substances. The objective of this study was to estimate the prevalence of substance use in patients admitted to the emergency room for non-fatal injuries. METHOD: A prospective cross-sectional study assessing all patients admitted to the emergency room within 6 hours after a non-fatal injury was conducted over a three-month period. The following were used as measures of alcohol and drug use: a standardized World Health Organization questionnaire; a self-administered questionnaire related to drug consumption within the 24 hours preceding contact; the Drug Abuse Screening Test; urine screens for cannabis, cocaine and benzodiazepines; and determination of blood alcohol concentration. Descriptive analyses were performed and the confidence interval used was 95%. RESULTS: A total of 353 patients were included. Cannabis and cocaine screens were conducted for 242 patients and benzodiazepine screens were conducted for 166. Blood alcohol concentrations reached the level of positivity in 11% (n = 39, and 10% (n = 33 presented some degree of intoxication. Among the 242 patients screened, 13.6% (n = 33 tested positive for cannabis, and 3.3% (n = 8 tested positive for cocaine, whereas 4.2% (n = 7 of the 166 patients screened tested positive for benzodiazepines. CONCLUSIONS: Substance use was highly prevalent among these individuals. In this sample, the frequency for the use of cannabis (an illicit drug was comparable to that of alcohol. More studies are needed in order to characterize such use among Brazilians and to develop proper approaches to such cases, with the aim of reducing substance use and its consequences.

    Fibromyalgia syndrome (FS) is a rheumatic syndrome affecting to 2-3% of individuals of productive age, mainly women. Neuroendocrine and genetic factors may play a significant role in development of the disease which is characterized by diffuse chronic pain and presence of tender points. Several studies have suggested an association between FS, especially pain sensitivity, and polymorphism of the catechol-O-methyltransferase (COMT) gene. The aim of the present study was to characterize the SNPs rs4680 and rs4818 of the COMT gene and assess its influence in pain sensitivity of patients with fibromyalgia screened by the Fibromyalgia Impact Questionnaire (FIQ). DNA was extracted from peripheral blood of 112 patients with fibromyalgia and 110 healthy individuals and was used as template in PCR for amplification of a 185-bp fragment of the COMT gene. The amplified fragment was sequenced for analyses of the SNPs rs4680 and rs4818. The frequency of mutant genotype AA of SNP rs6860 was 77.67% in patients with FS and 28.18% for the control group. For the SNP rs4818, the frequency of mutant genotype CC was 73.21 and 39.09% for patients with FS and controls, respectively. Moreover, the FIQ score was higher in patients with the homozygous mutant genotype for SNPs rs4680 (87.92 points) and rs4818 (86.14 points). These results suggest that SNPs rs4680 and rs4818 of the COMT gene may be associated with fibromyalgia and pain sensitivity in FS Brazilian patients.

    Full Text Available Background Determination of fecal calprotectin can provide an important guidance for the physician, also in primary care, in the differential diagnosis of gastrointestinal disorders, meanly between inflammatory bowel diseases and irritable bowel syndrome. Objectives The aims of the present study were to prospectively investigate, in Brazilian adults with gastrointestinal complaints, the value of fecal calprotectin as a biomarker for the differential diagnosis between functional and organic disorders and to correlate the concentrations with the activity of inflammatory bowel diseases. Methods The study included consecutive patients who had gastrointestinal complaints in which the measurement levels of fecal calprotectin were recommended. Fecal calprotectin was measured using a Bühlmann (Basel, Switzerland ELISA kit Results A total of 279 patients were included in the study, with median age of 39 years (range, 18 to 78 years. After clinical and laboratorial evaluation and considering the final diagnosis, patients were allocated into the following groups: a Irritable Bowel Syndrome: 154 patients (102 female and 52 male subjects. b Inflammatory Bowel Diseases group: 112 patients; 73 with Crohn’s disease; 38 female and 35 male patients; 52.1% (38/73 presented active disease, and 47.9% (35/73 had disease in remission and 39 patients with ulcerative colitis;19 female and 20 male patients; 48.7% (19/39 classified with active disease and 49.3% (20/39 with disease in remission. A significant difference (P<0.001 was observed between the median value of fecal calprotectin in Irritable Bowel Syndrome group that was 50.5 µg/g (IQR=16 - 294 µg/g; 405 µg/g (IQR=29 - 1980 µg/g in Crohn’s disease patients and 457 µg/g (IQR=25 - 1430 µg/g in ulcerative colitis patients. No difference was observed between the values found in the patients with Crohn’s disease and ulcerative colitis. Levels of fecal calprotectin were significantly lower in patients with

    To characterize the evolution of clinical and physiological variables in severe adult burn patients admitted to a Brazilian burn ICU, we hypothesized that characteristics of survivors are different from non-survivors after ICU admission. A five-year observational study was carried out. The clinical characteristics, physiological variables, and outcomes were collected during this period. A total of 163 patients required ICU support and were analyzed. Median age was 34 [25,47] years. Total burn surface area (TBSA) was 29 [18,43]%, and hospital mortality rate was 42%. Lethal burn area at which fifty percent of patients died (LA50%) was 36.5%. Median SAPS3 was 41 [34,54]. Factors associated with hospital mortality were analyzed in three steps, the first incorporated ICU admission data, the second incorporated first day ICU data, and the third incorporated data from the first week of an ICU stay. We found a significant association between hospital mortality and SAPS3 [OR(95%CI)=1.114(1.062-1.168)], TBSA [OR(95%CI)=1.043(1.010-1.076)], suicide attempts [OR(95%CI)=8.126(2.284-28.907)], and cumulative fluid balance per liter within the first week [OR(95%CI)=1.090(1.030-1.154)]. Inhalation injury was present in 45% of patients, and it was not significantly associated with hospital mortality. In this study of an ICU in a developing country, the mortality rate of critically ill burn patients was high and the TBSA was an independent risk factor for death. SAPS3 at admission and cumulative fluid balance in the first seven days, were also associated with unfavorable outcomes. The implementation of judicious fluid management after an acute resuscitation phase may help to improve outcomes in this scenario. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

    Full Text Available ABSTRACT Objectives: Innate immunity is involved in the physiopathology of ankylosing spondylitis (AS, with the participation of Gram-negative bacteria, modulation of human leukocyte antigen (HLA B27 and the involvement of pattern recognition receptors, such as Toll-like receptors (TLRs. The aim of this study was to investigate the clinical characteristics and frequency of TLR4 polymorphisms (Asp299Gly and Thr 399Ile in a cohort of Brazilian patients with AS. Methods: A cross-sectional study was carried out involving 200 patients with a diagnosis of AS and a healthy control group of 200 individuals. Disease activity, severity and functional capacity were measured. The study of TLR4 polymorphisms was performed using the restriction fragment length polymorphism method. HLA-B27 was analyzed by conventional polymerase chain reaction. The IBM SPSS Statistics 20 program was used for the statistical analysis, with p-values less than 0.05 considered significant. Results: Mean age and disease duration were 43.1 ± 12.7 and 16.6 ± 9.2 years, respectively. The sample was predominantly male (71% and non-Caucasian (52%. A total of 66% of the group of patients were positive for HLA-B27. The sample of patients was characterized by moderate functional impairment and a high degree of disease activity. No significant association was found between the two TLR4 polymorphisms and susceptibility to AS. Conclusions: TLR4 polymorphisms 399 and 299 were not more frequent in patients with AS in comparison to the health controls and none of the clinical variables were associated with these polymorphisms.

    Knowledge of the normal limits of the electrocardiogram (ECG) is mandatory for establishing which patients have abnormal ECGs. No studies have assessed the reference standards for a Latin American population. Our aim was to establish the normal ranges of the ECG for pediatric and adult Brazilian primary care patients. This retrospective observational study assessed all the consecutive 12-lead digital electrocardiograms of primary care patients at least 1 year old in Minas Gerais state, Brazil, recorded between 2010 and 2015. ECGs were excluded if there were technical problems, selected abnormalities were present or patients with selected self-declared comorbidities or on drug therapy. Only the first ECG from patients with multiple ECGs was accepted. The University of Glasgow ECG analysis program was used to automatically interpret the ECGs. For each variable, the 1st, 2nd, 50th, 98th and 99th percentiles were determined and results were compared to selected studies. A total of 1,493,905 ECGs were recorded. 1,007,891 were excluded and 486.014 were analyzed. This large study provided normal values for heart rate, P, QRS and T frontal axis, P and QRS overall duration, PR and QT overall intervals and QTc corrected by Hodges, Bazett, Fridericia and Framingham formulae. Overall, the results were similar to those from other studies performed in different populations but there were differences in extreme ages and specific measurements. This study has provided reference values for Latinos of both sexes older than 1 year. Our results are comparable to studies performed in different populations.

  6. Rare α0-thalassemia deletions detected by MLPA in five unrelated Brazilian patients

    Full Text Available Abstract Alpha-thalassemias are among the most common genetic diseases in the world. They are characterized by hypochromic and microcytic anemia and great clinical variability, ranging from a practically asymptomatic phenotype to severe anemia, which can lead to intrauterine or early neonatal death. Deletions affecting the α-globin genes, located on chromosome 16p13.3, are the main causes of α-thalassemia. Multiplex ligation-dependent probe amplification (MLPA can be used to detect rearrangements that cause α-thalassemia, particularly large deletions involving the whole α cluster and/or deletions in the HS-40 region. Here, MLPA was used to investigate the molecular basis of α-thalassemia in five unrelated patients, three of whom had Hb H disease. In addition to the -α3.7 deletion identified in the patients with Hb H disease, four different α0 deletions removing 15 to 225 kb DNA segments were found: two of them remove both the α genes, one affects only the regulatory element (HS-40 region, and another one extends over the entire α cluster and the HS-40 region. These results illustrate the diversity of α-thalassemia deletions in the Brazilian population and highlight the importance of molecular investigation in cases that present with microcytosis and hypochromia without iron deficiency and normal or reduced Hb A2 levels..

    Multiple Sulfatase Deficiency (MSD) is a rare autosomal recessive disease in which the activities of all sulfatases are reduced; its estimated prevalence is 1:1.4 million births. The disease is caused by mutations in SUMF1, which encodes an enzyme involved in the post-translational modification of sulfatases. The MSD phenotype is a combination of the clinical features found in diseases resulting from a deficiency of the individual sulfatases; i.e., mucopolysaccharidosis II, IIIA, IIID, IVA and VI, metachromatic leukodystrophy, X-linked ichthyosis, and the X-linked recessive form of chondrodysplasia punctata. We describe herein the first case of a Brazilian patient with MSD. The case was initially diagnosed as having mucopolysaccharidosis (MPS), due to skeletal alterations, coarse facial features, and urinary excretion of dermatan sulfate and heparan sulfate. Later, after a detailed biochemical investigation, the diagnosis of MSD was established. The analysis of the SUMF1 showed the patient was a compound heterozygote for two novel mutations (p.R349G and p.F244S). This case illustrates the challenges in the diagnosis of a disease considered rare, such as MSD. We point out that the availability of therapy for certain MPS disorders necessitates correct disease assignment, and the need to exclude the likelihood of MSD.

    Patient safety culture assessment allows hospitals to identify and prospectively manage safety issues in work routines. This article aimed to describe the cross-cultural adaptation of the Hospital Survey on Patient Safety Culture (HSOPSC) into Brazilian Portuguese. A universalist approach was adopted to assess conceptual, item, and semantic equivalence. The methodology involved the following stages: (1) translation of the questionnaire into Portuguese; (2) back-translation into English; (3) an expert panel to prepare a draft version; and (4) assessment of verbal understanding of the draft by a sample of the target population. The questionnaire was translated into Portuguese, and the scale's final version included 42 items. The target population sample assessed all the items as easy to understand. The questionnaire has been translated into Portuguese and adapted to the Brazilian hospital context, but it is necessary to assess its measurement equivalence, external validity, and reproducibility.

    Full Text Available Myocardial scintigraphy with meta-iodo-benzyl-guanidine (123I cMIBG has been studied in Parkinson's disease (PD, especially in Asian countries, but not in Latin America. Most of these studies include individuals with PD associated to a defined dysautonomia. Our goal is to report the cardiac sympathetic neurotransmission in de novo Brazilian patients with sporadic PD, without clinically defined dysautonomia. We evaluated retrospectively a series of 21 consecutive cases with PD without symptoms or signs of dysautonomia assessed by the standard bedside tests. This number was reduced to 14 with the application of exclusion criteria. 123I cMIBG SPECT up-take was low or absent in all of them and the heart/mediastinum ratio was low in 12 of 14. We concluded that 123I cMIBG has been able to identify cardiac sympathetic neurotransmission disorder in Brazilian de novo PD patients without clinically defined dysautonomia.

    Full Text Available INTRODUCTION: Nephrogenic diabetes insipidus is characterized by a lack of response in the distal nephron to the antidiuretic hormone arginine vasopressin. Manifestations include polyuria, polydipsia, hyposthenuria, recurrent episodes of dehydration and fever and growth failure. Most cases are caused by mutations in the AVPR2 gene. The mutant receptors are trapped intracellularly. METHOD: We studied five boys using clinical, laboratory and molecular data. The mean age at diagnosis was 14.6 months (range 6 to 24 and 12.2 years (7.8 to 19 after the follow-up period. The mean period of follow-up was 132.2 ± 50.9 months. RESULTS: The geometric means of the z-scores of weight and stature were -4.5 and -3.6, respectively, at diagnosis. At the last medical appointment, the z-scores of weight and stature were -0.3 and -0.9, respectively. Three patients were diagnosed with ureterohydronephrosis and exhibited increased post-void urine volume. Mutations in the AVPR2 gene were found in all patients, and the carrier status was confirmed in four of five cases. Two unrelated children presented identical mutations (S167L in arginine vasopressin R2. Two of the patients had a mutation that has already been described in other Brazilian families (R337X, and one patient showed a de novo mutation (Y128D in arginine vasopressin R2, since his mother's molecular analysis was normal. The recurrence risk for this family was significantly reduced. CONCLUSION: This study reports the clinical and laboratory characterization of Nephrogenic diabetes insipidus and reiterates the importance of the genetic basis that underlies the disease diagnosis and genetic counseling.

    Full Text Available The UCSD Performance-based Skills Assessment (UPSA is a measure of Functional Capacity and assesses skills involved in community tasks. It has good psychometrics properties, and is currently recommended as a co-primary assessment of cognition in the MATRICS Project. To our knowledge so far, there are no studies in western developing countries concerning Functional Capacity in Schizophrenia. The aims of this study were to translate, culturally adapt and validate the UPSA to assess Functional Capacity in community-dwelling patients with Schizophrenia living in Brazil. Eighty-two subjects (52 patients, 30 controls were evaluated using: the Brazilian version of the UPSA (UPSA-1-BR, PANSS, Personal and Social Performance (PSP and Global Assessment of Functioning (GAF. In the reliability test, UPSA-1-BR showed good Internal Consistency (Cronbach’s alpha of 0.88 and strong correlation between test and retest (4-month gap; r = 0.91; p < 0.01. Spearman’s rho values showed a moderate correlation between UPSA-1-BR and both PSP (0.50; p < 0.01 and GAF (0.46; p < 0.01 scores. UPSA-1-BR is capable of differentiating people with and without Schizophrenia. Patients scored lower than controls (58.9 versus 79.1, with an AUC of 0.79 (95%IC: 0.69–0.89. Sensitivity and specificity values of 0.71 and 0.70, respectively, were found in the cut-off point of 73.5, for separation of patients and controls, with predictive values of 80% (positive and 58% (negative. UPSA-B-BR was also evaluated. UPSA-1-BR and its brief version presented adequate psychometric properties and proved to be valid and reliable instruments in the assessment of Functional Capacity in subjects with Schizophrenia.

    Blessy Prabha Valsaraj

    2014-07-01

    Full Text Available Background: Any chronic illness puts a person and family at risk of long term suffering, financial depletion and burden on the caregiver. When it comes to chronic kidney disease (CKD, the sufferers have to be dependent on maintenance dialysis weekly twice or thrice that demands a lot of time and finances. Apart from that, they face physical symptoms of fatigue, anaemia, nausea, muscle cramps, fluctuating blood pressure and many other symptoms. They are asked to maintain a strict dietary, fluid and medication regimen in order to support the kidneys. Aims and Objectives: The current study aimed at exploring the lived experience of persons undergoing haemodialysis. Material and Methods: The study was conducted among ten patients undergoing maintenance dialysis who were diagnosed as having chronic kidney failure from the dialysis unit of Kasturba Hospital, which is a tertiary health care centre in South Karnataka. A qualitative approach with phenomenological research design was adopted. Data was obtained through interviews using a background proforma and semi-structured interview schedule. The data was analysed using Husserl's method. The transcripts were coded and analysed for common categories and themes were derived out of them. Results: The themes emerged at the end of the study were mental agony, physical limitations, coping, financial burden, lack of support, feelings towards the machine and dialysis, search for hope and betterment, spiritual coping, marital relationship and sexuality and uncertainty and fear of tomorrow. Conclusions: The authors conclude that the individual's life is centred on negatively oriented cognitions that can be modified with theoretically oriented interventions like cognitive behaviour therapy.

    The purpose of the study is to characterize the practices of Brazilian intensivists toward acute kidney injury (AKI) definition and management. A cross-sectional survey was conducted among 36 Brazilian hospitals. Of 731 ICU physicians invited to participate, 310 (42%) responded to the survey. Nearly half of the intensive care unit (ICU) physicians (146/310) do not apply AKIN and/or RIFLE definitions to their ICU patients. Most of the respondents prescribe intravenous fluids as a first-line therapeutic intervention for AKI patients. Although 38% of the surveyed physicians considered worsening of respiratory parameters to be the main criterion for stopping fluid infusion, only 15% considered daily net fluid balance as a criterion. Most of the respondents believed in the benefits of early renal replacement therapy (RRT) and considered worsening acidosis the most important criteria for starting early RRT. The main reason for a nephrologist referral was an urgently needed RRT. Despite recent advances in AKI definition and management, most of the surveyed ICU physicians in Brazil have not incorporated them in their clinical practice. Important differences in the management of AKI patients were observed among Brazilian ICU physicians, which is relevant for educational interventions and future research.

    To evaluate the access to medicines in primary health care of the Brazilian Unified Health System (SUS), from the patients' perspective. This is a cross-sectional study that used data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Services, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), conducted by interviews with 8,591 patients in cities of the five regions of Brazil. Evaluation of access to medicines used concepts proposed by Penshansky and Thomas (1981), according to the dimensions: availability, accessibility, accommodation, acceptability, and affordability. Each dimension was evaluated by its own indicators. For the "availability" dimension, 59.8% of patients reported having full access to medicines, without significant difference between regions. For "accessibility," 60% of patients declared that the basic health unit (UBS) was not far from their house, 83% said it was very easy/easy to get to the UBS, and most patients reported that they go walking (64.5%). For "accommodation," UBS was evaluated as very good/good for the items "comfort" (74.2%) and "cleanliness" (90.9%), and 70.8% of patients reported that they do not wait to receive their medicines, although the average waiting time was 32.9 minutes. For "acceptability," 93.1% of patients reported to be served with respect and courtesy by the staff of the dispensing units and 90.5% declared that the units' service was very good/good. For "affordability," 13% of patients reported not being able to buy something important to cover expenses with health problems, and 41.8% of participants pointed out the expense with medicines. Results show 70%-90% compliance, which is compatible with developed countries. However, access to medicines remains a challenge, because it is still heavily compromised by the low availability of essential medicines in public health units, showing that it does not occur universally, equally

    In the last few years, new primary immunodeficiencies and genetic defects have been described. Recently, immunoglobulin products with improved compositions and for subcutaneous use have become available in Brazil. In order to guide physicians on the use of human immunoglobulin to treat primary immunodeficiencies, based on a narrative literature review and their professional experience, the members of the Primary Immunodeficiency Group of the Brazilian Society of Allergy and Immunology prepared an updated document of the 1st Brazilian Consensus, published in 2010. The document presents new knowledge about the indications and efficacy of immunoglobulin therapy in primary immunodeficiencies, relevant production-related aspects, mode of use (routes of administration, pharmacokinetics, doses and intervals), adverse events (major, prevention, treatment and reporting), patient monitoring, presentations available and how to have access to this therapeutic resource in Brazil. RESUMO Nos últimos anos, novas imunodeficiências primárias e defeitos genéticos têm sido descritos. Recentemente, produtos de imunoglobulina, com aprimoramento em sua composição e para uso por via subcutânea, tornaram-se disponíveis em nosso meio. Com o objetivo de orientar o médico no uso da imunoglobulina humana para o tratamento das imunodeficiências primárias, os membros do Grupo de Assessoria em Imunodeficiências da Associação Brasileira de Alergia e Imunologia produziram um documento que teve por base uma revisão narrativa da literatura e sua experiência profissional, atualizando o I Consenso Brasileiro publicado em 2010. Apresentam-se novos conhecimentos sobre indicações e eficácia do tratamento com imunoglobulina nas imunodeficiências primárias, aspectos relevantes sobre a produção, forma de utilização (vias de administração, farmacocinética, doses e intervalos), efeitos adversos (principais efeitos, prevenção, tratamento e notificação), monitorização do

    The aims of this study were to investigate dental students' attitudes toward people living in poverty and the extent to which their perceptions were associated with their willingness to treat those patients in their future practice. All 910 dental students enrolled in three Brazilian public universities in 2010 were invited to take part in a cross-sectional survey. A total of 766 students (83.7% response rate) completed the self-administered questionnaire on their perceptions of and attitudes about poverty and their intention to provide dental care to poor people. The responding students showed slightly positive attitudes about people living in poverty; however, a high percentage (35%) reported thinking they were different from the rest of the population. Nevertheless, most of these students expressed willingness to provide care to underserved populations in their future practice; this willingness was found to be associated with their beliefs about poverty (OR 1.65; 95% CI=1.41-1.94). Overall, the study found that these dental students had altruistic views toward people living in poverty. However, they seemed to lack a deep understanding of poverty that may prevent them from acting on their good intentions.

    Individuals with diabetes develop lower extremity amputation for several reasons. Investigations into pathways to the development of complications are important both for treatment and prevention. To evaluate the relationship between amputation and risk factors in people with diabetes mellitus. All participants included in this study (n=165) were recruited from the Diabetic Foot Program, developed in a Brazilian University, over seven years (2007-2014) and all information for this study was extracted from their clinical records. The prevalence of amputation in patients with diabetes with four risk factors was up to 20% higher when compared to those with only one risk factor. The main predictive risk factors for amputation in this population were the presence of an ulcer and smoking. The risk factors for amputation can be predicted for people with diabetes mellitus and, in the present study, the main factors were the presence of an ulcer and the smoking habit.

    Changes in balance occur with the progression of Parkinson's disease (PD). To validate the Brazilian version of the Berg Balance Scale (BBS) for PD patients, determining its reliability and internal consistency and correlating it with PD-specific instruments. We evaluated 53 patients (M/F 37/16, mean age+/-SD, 62+/-7.9 years) with PD (mean+/-SD, 7.8+/-4.4 years). Unified Parkinson's Disease Rating Scale (UPDRS), Schwab and England Scale (SandE , Hoehn and Yahr Staging Scale (HY) and BBS were used to assess patients. Statistical analyses for inter-rater reliability, internal consistency and correlations among BBS, UPDRS, SandE and HY were performed. The mean scores+/-SD on UPDRS and BBS were, respectively, 41.6+/-17.8 and 47.2+/-8.2. The median on SandE and HY scales were 80% and 2.5, respectively. The BBS presented a high intra-class correlation coefficient (ICC=0.84) and internal consistency (Cronbrach's alpha=0.92). There was a statistically significant correlation between BBS and disease duration (r(s)= -0.520, p<0.001), UPDRS subscales II and III (r(s)= -0.467, p=0.011; r(s)= -0.374, p=0.046, respectively), stage of disease (HY; r(s)= -0.507, p<0.001) and the activities of daily living (SandE; r(s)=0.492, p<0.001). The BBS is a promising tool for the assessment of balance in PD, correlating with the stage of disease and the level of independence.

    Full Text Available Nosocomial infections (NI are frequent events with potentially lethal outcomes. We identified predictive factors for mortality related to NI and developed an algorithm for predicting that risk in order to improve hospital epidemiology and healthcare quality programs. We made a prospective cohort NI surveillance of all acute-care patients according to the National Nosocomial Infections Surveillance System guidelines since 1992, applying the Centers for Disease Control and Prevention 1988 definitions adapted to a Brazilian pediatric hospital. Thirty-eight deaths considered to be related to NI were analyzed as the outcome variable for 754 patients with NI, whose survival time was taken into consideration. The predictive factors for mortality related to NI (p < 0.05 in the Cox regression model were: invasive procedures and use of two or more antibiotics. The mean survival time was significantly shorter (p < 0.05 with the Kaplan-Meier method for patients who suffered invasive procedures and for those who received two or more antibiotics. Applying a tree-structured survival analysis (TSSA, two groups with high mortality rates were identified: one group with time from admission to the first NI less than 11 days, received two or more antibiotics and suffered invasive procedures; the other group had the first NI between 12 and 22 days after admission and was subjected to invasive procedures. The possible modifiable factors to prevent mortality involve invasive devices and antibiotics. The TSSA approach is helpful to identify combinations of predictors and to guide protective actions to be taken in continuous-quality-improvement programs.

  5. Endotoxaemia in haemodialysis: a novel factor in erythropoetin resistance?

    Laura E A Harrison

    Full Text Available BACKGROUND/OBJECTIVES: Translocated endotoxin derived from intestinal bacteria is a driver of systemic inflammation and oxidative stress. Severe endotoxaemia is an underappreciated, but characteristic finding in haemodialysis (HD patients, and appears to be driven by acute repetitive dialysis induced circulatory stress. Resistance to erythropoietin (EPO has been identified as a predictor of mortality risk, and associated with inflammation and malnutrition. This study aims to explore the potential link between previously unrecognised endotoxaemia and EPO Resistance Index (ERI in HD patients. METHODOLOGY/PRINCIPAL FINDINGS: 50 established HD patients were studied at a routine dialysis session. Data collection included weight, BMI, ultrafiltration volume, weekly EPO dose, and blood sampling pre and post HD. ERI was calculated as ratio of total weekly EPO dose to body weight (U/kg to haemoglobin level (g/dL. Mean haemoglobin (Hb was 11.3±1.3 g/dL with a median EPO dose of 10,000 [IQR 7,500-20,000] u/wk and ERI of 13.7 [IQR 6.9-23.3] ((U/Kg/(g/dL. Mean pre-HD serum ET levels were significantly elevated at 0.69±0.30 EU/ml. Natural logarithm (Ln of ERI correlated to predialysis ET levels (r = 0.324, p = 0.03 with a trend towards association with hsCRP (r = 0.280, p = 0.07. Ln ERI correlated with ultrafiltration volume, a driver of circulatory stress (r = 0.295, p = 0.046, previously identified to be associated with increased intradialytic endotoxin translocation. Both serum ET and ultrafiltration volume corrected for body weight were independently associated with Ln ERI in multivariable analysis. CONCLUSIONS: This study suggests that endotoxaemia is a significant factor in setting levels of EPO requirement. It raises the possibility that elevated EPO doses may in part merely be identifying patients subjected to significant circulatory stress and suffering the myriad of negative biological consequences arising from sustained

    The 5382insC mutation in BRCA1 is a frequently reported mutation, being very prevalent in Central and Eastern Europe. This mutation was recurrently reported in Brazil and one case was reported Portugal, but not in Spain and other South-American countries,. We analyzed the haplotypic profile of seven Brazilian carriers of 5382insC to characterize a possible founder effect. The analyses indicated that mutation carriers shared an identical haplotype. The absence of this mutation in Spain, other South American countries, and sub-Saharan populations, as well as the patients' own ancestry, point to a significant Central or Eastern European contribution to the present genetic background of Brazilian population, different from the population structuring of remaining South American countries.

    This study aimed to better understand the carbon emission impact of haemodialysis (HD) throughout Australia by determining its carbon footprint, the relative contributions of various sectors to this footprint, and how contributions from electricity and water consumption are affected by local factors. Activity data associated with HD provision at a 6-chair suburban satellite HD unit in Victoria in 2011 was collected and converted to a common measurement unit of tonnes of CO2 equivalents (t CO2-eq) via established emissions factors. For electricity and water consumption, emissions factors for other Australian locations were applied to assess the impact of local factors on these footprint contributors. In Victoria, the annual per-patient carbon footprint of satellite HD was calculated to be 10.2t CO2-eq. The largest contributors were pharmaceuticals (35.7%) and medical equipment (23.4%). Throughout Australia, the emissions percentage attributable to electricity consumption ranged from 5.2% to 18.6%, while the emissions percentage attributable to water use ranged from 4.0% to 11.6%. State-by-state contributions of energy and water use to the carbon footprint of satellite HD appear to vary significantly. Performing emissions planning and target setting at the state level may be more appropriate in the Australian context. What is known about the topic? Healthcare provision carries a significant environmental footprint. In particular, conventional HD uses substantial amounts of electricity and water. In the UK, provision of HD and peritoneal dialysis was found to have an annual per-patient carbon footprint of 7.1t CO2-eq. What does this paper add? This is the first carbon-footprinting study of HD in Australia. In Victoria, the annual per-patient carbon footprint of satellite conventional HD is 10.2t CO2-eq. Notably, the contributions of electricity and water consumption to the carbon footprint varies significantly throughout Australia when local factors are taken into

  8. Diversity of breakpoints of variant Philadelphia chromosomes in chronic myeloid leukemia in Brazilian patients

    2015-02-01

    Full Text Available Background: Chronic myeloid leukemia is a myeloproliferative disorder characterized by the Philadelphia chromosome or t(9;22(q34.1;q11.2, resulting in the break-point cluster regionAbelson tyrosine kinase fusion gene, which encodes a constitutively active tyrosine kinase protein. The Philadelphia chromosome is detected by karyotyping in around 90% of chronic myeloid leukemia patients, but 5-10% may have variant types. Variant Philadelphia chromosomes are characterized by the involvement of another chromosome in addition to chromosome 9 or 22. It can be a simple type of variant when one other chromosome is involved, or complex, in which two or more chromosomes take part in the translocation. Few studies have reported the incidence of variant Philadelphia chromosomes or the breakpoints involved among Brazilian chronic myeloid leukemia patients. Objective: The aim of this report is to describe the diversity of the variant Philadelphia chromosomes found and highlight some interesting breakpoint candidates for further studies. Methods: the Cytogenetics Section Database was searched for all cases with diagnoses of chronic myeloid leukemia during a 12-year period and all the variant Philadelphia chromosomes were listed. Results: Fifty (5.17% cases out of 1071 Philadelphia-positive chronic myeloid leukemia were variants. The most frequently involved chromosome was 17, followed by chromosomes: 1, 20, 6, 11, 2, 10, 12 and 15. Conclusion: Among all the breakpoints seen in this survey, six had previously been described: 11p15, 14q32, 15q11.2, 16p13.1, 17p13 and 17q21. The fact that some regions get more fre- quently involved in such rare rearrangements calls attention to possible predisposition that should be further studied. Nevertheless, the pathological implication of these variants remains unclear.

    Transcultural studies regarding the comparison of levels of burden in caregivers of patients with Alzheimer's disease (AD) from Europe and Latin America are rare. We designed this study to investigate the differentiating factors associated with burden in Brazilian and Spanish caregivers of patients with AD. This is a cross-sectional study composed by samples of outpatients with AD and their caregivers from Brazil (n = 128) and Spain (n = 146). Caregivers answered the Zarit Burden Interview (ZBI) and a Sociodemographic Questionnaire. Patients were assessed with the Mini-Mental State Examination (MMSE), Functional Activities Questionnaire (FAQ), Disability Assessment for Dementia (DAD), Neuropsychiatric Inventory (NPI), and Clinical Dementia Rating (CDR) Scale. In the multivariate regression analysis, high burden levels were reported in Brazil, when caregivers were female (p = 0.025) and when patients did not attend Day Care Center (p = 0.025). In Spain, high burden levels were associated with living with the patient (p = 0.014), younger caregivers (p = 0.003), and participation of patients at Day Care Center (p = 0.046). Also, different neuropsychiatric symptoms explained high burden levels: in Brazil, depression (p < 0.001) and anxiety (p = 0.024) and, in Spain, apathy/indifference (p < 0.001), agitation/aggression (p = 0.019) and irritability/lability (p = 0.027). Caregivers' gender, patients who attended Day Care Center and neuropsychiatric symptoms were differentiating factors in the burden of Brazilian and Spanish caregivers.

    Purpose Leber hereditary optic neuropathy (LHON) is a mitochondrial disease characterized by bilateral vision loss. More than 95% of LHON cases are associated with one of the three main mtDNA mutations: G11778A, T14484C, and G3460A. The other 5% of cases are due to other rare mutations related to the disease. The aim of this study was to identify the prevalence and spectrum of LHON mtDNA mutations, including the haplogroup, in a cohort of Brazilian patients with optic neuropathy and to evaluate the usefulness of iPLEX Gold/matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) technology in detecting LHON mutations. Methods We analyzed a total of 101 patients; 67 had a clinical diagnosis of LHON and 34 had optic neuropathy of unknown etiology. Direct sequencing and iPLEX Gold/MALDI-TOF MS were used to screen for the most common pathogenic point mutations in LHON, together with the rare mutations G3733A, C4171A, T10663C, G14459A, C14482G, A14495G, C14568T, and C14482A. Results We identified mutations in 36 patients, of whom 83.3% carried the G11778A mutation and 16.7% carried the T14484C mutation. In individuals with mutations, the haplogroups found were L1/L2, L3, C, R, U, D, and H. Rare mutations were not detected in any of the patients analyzed. Conclusions The frequencies of the main LHON mutations were similar to those previously reported for Latin America. A different frequency was found only for the A3460G mutation. The most frequent haplogroups identified were of African origin. The iPLEX Gold/MALDI-TOF MS technology proved to be highly accurate and efficient for screening mutations and identifying the haplogroups related to LHON. The MassArray platform, combined with other techniques, enabled definitive diagnosis of LHON in 36% (36/101) of the cases studied. PMID:27582625

    Acute compartment syndrome is a well-described surgical emergency that requires immediate diagnosis and operative intervention. Vascular access-associated compartment syndrome is rarely reported in haemodialysis patients. The purpose of this article is to document evidence that catheter-related puncture, which results in arteriovenous fistula injury in uraemia, may cause acute forearm compartment syndrome. Between September 2007 and September 2012, five consecutive patients presented to our section with tense swollen forearms with skin blistering, decreased hand sensation and reduced capillary return in the fingers. Their ages ranged from 65 to 81 years (mean 72.8 years). All of the patients underwent emergent exploration after the diagnosis of acute forearm compartment syndrome. The patients' details were reviewed. The time interval between dialysis completion and return to the emergency department ranged from 6 to 9 h (mean 7.4 h). During operation, the bleeding was found to originate from the site of the fistula puncture and was repaired with 9-0 nylon suture under microscopy. After adequate wound care, a reconstructive procedure with a split-thickness skin graft was performed in all of the five patients. There was no vascular or neurological deficit of the forearm or hand within the mean follow-up period of 14.8 months (range 12-18 months). In this series, we report five cases of forearm compartment syndrome in uraemia, secondary to bleeding from a catheter-related puncture of a haemodialysis access fistula. However, there is no case series that focuses upon this specific topic in the present literature. This problem deserves more attention. © 2014 Royal Australasian College of Surgeons.

    This study examined the reliability and validity of the Brazilian Portuguese version of the Treatment Satisfaction Questionnaire for Medication (version 1.4) among patients with hypertension. Understanding the patient experience with treatment satisfaction will contribute to improved medication adherence and control of hypertension. Hypertension is a serious problem in Brazil that is associated with chronic illness controlled, in part, by consistent adherence to medications. Patient satisfaction with medication treatment is associated with adherence to medication. The Treatment Satisfaction Questionnaire for Medication (version 1.4) is a promising instrument for measuring medication; however, to date there has been no report of the reliability and validity of the instrument with Portuguese-speaking adults with hypertension in Brazil. Cross-sectional descriptive exploratory study. A convenience sample of 300 patients with hypertension in an outpatient setting in the southeast region of São Paulo state in Brazil completed the Treatment Satisfaction Questionnaire for Medication (version 1.4). The instrument, comprised of four subscales, was evaluated for reliability using correlation analyses and internal consistency. Confirmatory factor analysis was used to determine factorial validity. Correlational analyses, internal consistency (Cronbach's alpha) and hierarchical confirmatory factor analysis demonstrate adequate support for the four-factor dimensionality, reliability and factorial validity of the Treatment Satisfaction Questionnaire for Medication (version 1.4). This study provides modest evidence for internal consistency and factorial validity of the Treatment Satisfaction Questionnaire for Medication (version 1.4) in Portuguese-speaking adult Brazilians with hypertension. Future testing should focus on extending reliability testing, discriminant validity and potential translation and literacy issues in this population. Within known limitations, clinicians will

    Background Left atrial volume index (LAVI) increase has been associated to left ventricle (LV) diastolic dysfunction (DD), a marker of cardiovascular events (atrial fibrillation, stroke, heart failure, death). Objective To evaluate the relationship between LAVI and diferente grades od DD in Brazilian patients submitted to echocardiogram, studying LAVI increase determinants in this sample. Methods We have selected 500 outpatients submitted to echocardiography, after excluding arrhythmia, valvar or congenital cardiopathy, permanent pacemaker or inadequate ecocardiographic window. LAVI was obtained according to Simpson's method. DD was classified according to current guidelines. The clinical and echocardiographic variables were submitted to linear regression multivariate analysis. Results Mean age was 52 ± 15 years old, 53% were male, 55% had arterial hypertension, 9% had coronary artery disease, 8% were diabetic, 24% were obese, 47% had LV hypertrophy. The mean ejection fraction of the left ventricle was 69.6 ± 7,2%. The prevalence of DD in this sample was 33.8% (grade I: 66%, grade II: 29% e grade III: 5%). LAVI increased progressively according to DD grade: 21 ± 4 mL/m2 (absent), 26 ± 7 mL/m2 (grade I), 33 ± 5 mL/m2 (grade II), 50 ± 5 mL/m2 (grade III) (p < 0,001). In this sample, LAVI increase independent predictors were age, left ventricular mass, relative wall thickness, LV ejection fraction and E/e' ratio. Conclusion DD contributes to left atrial remodeling. LAVI increases as an expression of DD severity and is independently associated to age, left ventricle hypertrophy, systolic dysfunction and increased LV filling pressures. PMID:23702813

    The prevalence of HIV among psychiatric patients is higher than general population rates worldwide. Many risk behaviors have been identified in studies from both developing and developed countries, though sampling limitations restrict the generalizability of their results. The objective of this study was to report findings from the first national sample of psychiatric patients about lifetime practice of unsafe sex and associated factors. A national multicenter sample of adults with mental illness was randomly selected from 26 public mental health institutions throughout Brazil. Sociodemographic, sexual behavior and clinical data were obtained from person-to-person interviews and blood was collected for serology testing. Logistic regression was used for analysis. The overall prevalence of lifetime unprotected sex was 80.3%. Married, older, female patients, those with multiple partners and living with children or partners only and those with less severe psychiatric diagnosis more often practised unsafe sex. Risk behavior assessment is a critical tool for clinicians to be able to determine needed HIV-related services for their clients and ensure appropriate follow-through with care and prevention. Interventions that address situational risks in psychiatric patients' lives-institutional and individual- and increase their ability to make informed decisions about their sexual health are urgently needed.

    To determine the value of denatured homologous vein grafts as a conduit for secondary haemodialysis access. Retrospective clinical study. 2 University Hospitals. One-hundred-and-twenty-five patients received 195 grafts over a period of five years. Fifty-six first grafts (45%) functioned without complications throughout the study period of 5.8 years. Primary patency was 57% after 1 year and 25% after 3 years of follow-up. Of the initial grafts, 69 (55%) needed 161 interventions, for thrombosis (n = 59), stenosis (n = 43), failure beyond repair (n = 40), aneurysm (n = 12), infection (n = 4), steal syndrome (n = 1), and other causes (n = 2). Secondary patency was 76% at 1 year and 52% at 3 years of follow-up. A major advantage of these grafts was the low rate (2.6%) of infection. Aneurysm formation occurred 17 times in 195 grafts (8.7%). Denatured homologous vein graft is a good alternative in secondary access surgery.

    Hypernatraemia is a common and potentially serious condition in the intensive care unit (ICU). We present a case, a 84-year-old man, who was admitted to the ICU with septic shock due to pneumonia. After successful fluid resuscitation and antibiotic treatment the patient was stable, but severely oedematose and developed hypernatraemia (S-Na 165 mmol/l) with cerebral symptoms. Urine-Na was very low. The condition was successfully treated with continuous veno-venous haemodialysis (CVVHD), adding extra Na to the dialysate in order to correct the hypernatraemia at a rate of 8-15 mmol/l per day. Correction of hypernatremia using CVVHD is effective and safe.

    Full Text Available Background: Chronic haemodialysis for adult patients with end-stage kidney failure requires a patent extracorporeal circuit, maintained by anticoagulants such as unfractionated heparin (UFH. Incorrect administration of UFH has safety implications for patients.Objectives: Firstly, to describe renal practitioners’ self-reported knowledge, attitudes and practice (KAP regarding the safe use of UFH and its effects; secondly, to determine an association between KAP and selected independent variables.Method: A cross-sectional descriptive survey by self-administered questionnaire and non-probability convenience sampling was conducted in two tertiary hospital dialysis units and five private dialysis units in 2013.Results: The mean age of 74/77 respondents (96.1%, was 41.1 years. Most (41/77, 53.2% had 0–5 years of renal experience. The odds of enrolled nurses having poorer knowledge of UFH than registered nurses were 18.7 times higher at a 95% Confidence Interval (CI (1.9–187.4 and statistically significant (P = 0.013. The odds of delivering poor practice having ≤ five years of experience and no in-service education were 4.6 times higher at a 95% CI (1.4–15.6, than for respondents who had ≥ six years of experience (P = 0.014 and 4.3 times higher (95% CI 1.1–16.5 than for respondents who received in-service education (P = 0.032, the difference reaching statistical significance in both cases.Conclusion: Results suggest that the category of the professional influences knowledge and, thus, safe use of UFH, and that there is a direct relationship between years of experience and quality of haemodialysis practice and between having in-service education and quality of practice.

    The key to treatment of a thrombosed dialysis graft is restoration and maintenance of function as long as possible. The objective of this study was to compare the outcomes of pharmacomechanical thrombolysis and surgical thrombectomy in the treatment of thrombosed haemodialysis grafts. During a 3-year period, 108 patients with 114 thrombosed dialysis grafts were referred to our institute for treatment. Fifty thrombosed dialysis grafts underwent pulse-spray catheter thrombolysis using recombinant tissue plasminogen activator (rt-PA) with angioplasty, and 64 thrombosed dialysis grafts underwent surgical thrombectomy. The procedural success rates, complications and average patency times and patency rates were compared between the 2 procedures. P values less than 0.05 were considered to be statistically significant. There were no statistically significant differences between the pharmacomechanical thrombolysis group and the thrombectomy group in the procedural success rates (94% and 93.8%, P = 0.15) or average patency times (6.24 months and 6.30 months, P = 0.17). The primary and secondary patency rates at 12 months were 28.0% ± 8.4% and 54.3% ± 7.8% for the thrombolysis with angioplasty group, and 30.0% ± 6.3% and 57.0% ± 4.8% for the thrombectomy group, respectively (P = 0.65 and P = 0.49, respectively). There were no procedural-related major complications. Our study found no differences in outcomes between patients treated with pharmacomechanical thrombolysis and surgical thrombectomy for thrombosed haemodialysis grafts. Pharmacomechanical thrombolysis can be considered as an alternative treatment for dialysis graft thrombosis.

    Full Text Available Adrenoleukodystrophy (X-ALD is an X-linked recessively inherited peroxisomal disorder, phenotypically heterogeneous, characterized by progressive white-matter demyelination of the central nervous system and adrenocortical insufficiency. We investigated 15 male X-ALD patients varying in age from 7 to 39, diagnosed among 108 suspected patients referred for investigation. Plasma levels of very long chain fatty acids (VLCFA were measured at our laboratory using gas chromatography (GC. Eleven cases of childhood X-ALD and four cases of adrenomyeloneuropathy (AMN were diagnosed. Adrenal leukodystrophy insufficiency and limb weakness were the most frequent symptoms, appearing in 12, 8 and 6 of the patients, respectively. Physician awareness of X-ALD seems inadequate to judge by age at diagnosis and lengthy interval between the start of symptoms and diagnosis. This is the first published series of Brazilian patients with X-ALD. We determined signs and symptoms relevant for diagnosis, as early identification seems important for treatment outcome. In addition, diagnosis identifies carriers, who could benefit from genetic counselling and prenatal diagnosis.Adrenoleucodistrofia (X-ALD é uma desordem peroxissomal com padrão de herança ligada ao X, fenotipicamente heterogênea, caracterizada por uma progressiva desmielinização da substância branca do sistema nervoso central e por insuficiência adrenal.

    Full Text Available ABSTRACT Survival rates of critically ill patients with liver disease has sharply increased in recent years due to several improvements in the management of decompensated cirrhosis and acute liver failure. This is ascribed to the incorporation of evidence-based strategies from clinical trials aiming to reduce mortality. In order to discuss the cutting-edge evidence regarding critical care of patients with liver disease, a joint single topic conference was recently sponsored by the Brazilian Society of Hepatology in cooperation with the Brazilian Society of Intensive Care Medicine and the Brazilian Association for Organ Transplantation. This paper summarizes the proceedings of the aforementioned meeting and it is intended to guide intensive care physicians, gastroenterologists and hepatologists in the care management of patients with liver disease.

    Fibromyalgia (FM) is a complex syndrome that is characterized by lasting and diffuse chronic musculoskeletal pain, derived from non-inflammatory causes and classically associated with the presence of specific tender points. However, studies have highlighted other important symptoms associated with a lower quality of life (QOL) in FM, such as sleep disturbances and alexithymia. This study aimed to investigate the pain, sleep and alexithymia patterns of FM patients treated in a Brazilian tertiary center. 20 patients with FM who were followed-up in the Rheumatology outpatient clinic of a Brazilian tertiary center (Faculdade de Medicina de São José do Rio Preto - FAMERP, São Paulo, Brazil) and 20 patients without FM from other outpatient services of the FAMERP completed a clinical and socio-demographic questionnaire, the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI), the Toronto Alexithymia Scale (TAS-20) and the SF-36 (WHOQOL). The patients with FM presented worse performances in all QOL dimensions of the SF-36 and higher scores on the PSQI (p=0.01), and the TAS-20 (p=0.02). Patients with FM also scored significantly higher in all specific domains of PSQI and TAS-20. The present data were in accordance with literature, disclosing a worse performance of patients with FM on pain impact, sleep complains and more presence of alexithymia. Studies have disclosed the presence of important and frequently underdiagnosed symptoms beyond pain complaints in FM, such as sleep complaints and alexithymia, and a better knowledge of such disturbances might improve FM patients' approach and treatment.

    To translate, adapt and evaluate the properties of a Brazilian Portuguese version of the Spoken Knowledge in Low Literacy Patients with Diabetes, which is a questionnaire that evaluate diabetes knowledge. A cross-sectional study with type 2 diabetes patients aged ≥60 years, seen at a public healthcare organization in the city of Sao Paulo (SP). After the development of the Portuguese version, we evaluated the psychometrics properties and the association with sociodemographic and clinical variables. The regression models were adjusted for sociodemographic data, functional health literacy, duration of disease, use of insulin, and glycemic control. We evaluated 129 type 2 diabetic patients, with mean age of 75.9 (±6.2) years, mean scholling of 5.2 (±4.4) years, mean glycosylated hemoglobin of 7.2% (±1.4), and mean score on Spoken Knowledge in Low Literacy Patients with Diabetes of 42.1% (±25.8). In the regression model, the variables independently associated to Spoken Knowledge in Low Literacy Patients with Diabetes were schooling (B=0.193; p=0.003), use of insulin (B=1.326; p=0.004), duration of diabetes (B=0.053; p=0.022) and health literacy (B=0.108; p=0.021). The determination coefficient was 0.273. The Cronbach a was 0.75, demonstrating appropriate internal consistency. This translated version of the Spoken Knowledge in Low Literacy Patients with Diabetes showed to be adequate to evaluate diabetes knowledge in elderly patients with low schooling levels. It presented normal distribution, adequate internal consistency, with no ceiling or floor effect. The tool is easy to be used, can be quickly applied and does not depend on reading skills.

    Full Text Available Parkinson's disease is the second most frequent neurodegenerative disorder in the world, affecting 1-2% of individuals over the age of 65. The etiology of Parkinson's disease is complex, with the involvement of gene-environment interactions. Although it is considered a disease of late manifestation, early-onset forms of parkinsonism contribute to 5–10% of all cases. In the present study, we screened mutations in coding regions of PARK2 and PINK1 genes in 136 unrelated Brazilian patients with early-onset Parkinson's disease through automatic sequencing. We identified six missense variants in PARK2 gene: one known pathogenic mutation, two variants of uncertain role, and three nonpathogenic changes. No pathogenic mutation was identified in PINK1 gene, only benign polymorphisms. All putative pathogenic variants found in this study were in heterozygous state. Our data show that PARK2 point mutations are more common in Brazilian early-onset Parkinson's disease patients (2.9% than PINK1 missense variants (0%, corroborating other studies worldwide.

    Circadian rhythms comprise of daily oscillations in a variety of biological processes and are regulated by an endogenous clock. Disruption of these rhythms has been associated with cancer progression, and understanding natural oscillations in cellular growth control, tumor suppression and cancer treatment, may reveal how clock and clock‑controlled genes are regulated in normal physiological functioning. To investigate the association between clock genes and non‑small cell lung cancer (NSCLC), we genotyped three tag SNPs (rs938836, rs17050680, rs3805213) in the Nocturnin gene (CCRN4L), five SNPs (rs228727, rs228644, rs228729, rs707467, rs104620202) in the period 3 (PER3) gene and one SNP (rs6855837) in the CLOCK gene, in 78 Brazilian patients with NSCLC. One tag SNP in CCRN4L (rs3805213) and another tag SNP from PER3 (rs228729) demonstrated a significant correlation with genotype and allele frequency in lung cancer (P=4.4x10‑3 and P=5.7x10‑2; P=0.004 and P=0.02, respectively). The results of our study suggest these polymorphisms in the CCRN4L and PER3 genes may represent a risk factor in the occurrence and development of NSCLC in Brazilian patients.

    Arteriovenous fistula (AVF) formation for long-term haemodialysis in children is a niche discipline with little data for guidance. We developed a dedicated Vascular Access Clinic that is run jointly by a transplant surgeon, paediatric nephrologist, dialysis nurse and a clinical vascular scientist specialised in vascular sonography for the assessment and surveillance of AVFs. We report the experience and 2-year outcomes of this clinic. Twelve new AVFs were formed and 11 existing AVFs were followed up for 2 years. All children were assessed by clinical and ultrasound examination. During the study period 12 brachiocephalic, nine basilic vein transpositions and two radiocephalic AVFs were followed up. The median age (interquartile range) and weight of those children undergoing new AVF creation were 9.4 (interquartile 3-17) years and 26.9 (14-67) kg, respectively. Pre-operative ultrasound vascular mapping showed maximum median vein and artery diameters of 3.0 (2-5) and 2.7 (2.0-5.3) mm, respectively. Maturation scans 6 weeks after AVF formation showed a median flow of 1277 (432-2880) ml/min. Primary maturation rate was 83 % (10/12). Assisted maturation was 100 %, with two patients requiring a single angioplasty. For the 11 children with an existing AVF the maximum median vein diameter was 14.0 (8.0-26.0) mm, and the median flow rate was 1781 (800-2971) ml/min at a median of 153 weeks after AVF formation. Twenty-two AVFs were used successfully for dialysis, a median kt/V of 1.97 (1.8-2.9), and urea reduction ratio of 80.7 % (79.3-86 %) was observed. One child was transplanted before the AVF was used. A multidisciplinary vascular clinic incorporating ultrasound assessment is key to maintaining young children on chronic haemodialysis via an AVF.

    Full Text Available Alzheimer’s disease (AD is characterized by disorders that can impair the nutrition of the patient and lead to weight loss and nutritional deficits during the course of the disease. The aim of this study was to assess the nutritional status and food intake of Brazilian patients with Alzheimer’s disease at 3 different stages of the disease. The sample consisted of 30 subjects of both genders, mean age 77 years, with probable AD. Subjects were assessed by collecting anthropometric data, the Mini Nutritional Assessment (MNA, serum albumin content, Mini Mental State Examination and 24-hour records of food and drink. Although a steady decrease in average weight was observed as the disease progressed (CDR1: 70.8±15.9 kg; CDR2: 61.4±15.7 kg; CDR3: 56.1± 8.4 kg, the differences were not significant. MNA and serum albumin both fell during the progression of the disease (p = 0.042; p = 0.047, respectively and, at the severe stage, half the patients were found to be undernourished and the other half at risk of undernutrition. According to their body mass index, 23.3% of patients were overweight. The nutritional value of the food consumed was similar across the stages of AD. In conclusion, the majority of Brazilian patients with AD in this study exhibited cognitive decline and malnutrition. However, food intake was similar among the stages of the disease, thus having no direct association with the progression of AD.

    One of the most important pathogenetic factors involved in the onset of intradialysis arrhytmias is the alteration in electrolyte concentration, particularly potassium (K(+)). Two studies were performed: Study A was designed to investigate above all the isolated effect of the factor time t on intradialysis K(+) mass balance (K(+)MB): 11 stable prevalent Caucasian anuric patients underwent one standard (∼4 h) and one long-hour (∼8 h) bicarbonate haemodialysis (HD) session. The latter were pair-matched as far as the dialysate and blood volume processed (90 L) and volume of ultrafiltration are concerned. Study B was designed to identify and rank the other factors determining intradialysis K(+)MB: 63 stable prevalent Caucasian anuric patients underwent one 4-h standard bicarbonate HD session. Dialysate K(+) concentration was 2.0 mmol/L in both studies. Blood samples were obtained from the inlet blood tubing immediately before the onset of dialysis and at t60, t120, t180 min and at end of the 4- and 8-h sessions for the measurement of plasma K(+), blood bicarbonates and blood pH. Additional blood samples were obtained at t360 min for the 8 h sessions. Direct dialysate quantification was utilized for K(+)MBs. Direct potentiometry with an ion-selective electrode was used for K(+) measurements. Study A: mean K(+)MBs were significantly higher in the 8-h sessions (4 h: -88.4 ± 23.2 SD mmol versus 8 h: -101.9 ± 32.2 mmol; P = 0.02). Bivariate linear regression analyses showed that only mean plasma K(+), area under the curve (AUC) of the hourly inlet dialyser diffusion concentration gradient of K(+) (hcgAUCK(+)) and AUC of blood bicarbonates and mean blood bicarbonates were significantly related to K(+)MB in both 4- and 8-h sessions. A multiple linear regression output with K(+)MB as dependent variable showed that only mean plasma K(+), hcgAUCK(+) and duration of HD sessions per se remained statistically significant. Study B: mean K(+)MBs were -86.7 ± 22.6 mmol

    The hepatitis C virus (HCV) infection affects about 2% of the world's population and can cause chronic liver infection and persistent long-term sequelae such as cirrhosis and liver cancer.The prevalence of HCV infection among people on haemodialysis is often higher than the general population. The virus is easily transmitted parenterally, and blood transfusions have previously played a significant role in transmission; however, erythropoietin therapy has reduced the need for transfusions, and coupled with improved screening of donated blood, has significantly decreased transmission by transfusion. Although control of hospital-acquired infection has improved with the advent of biosafety measures, stopping HCV transmission in haemodialysis units remains challenging.Isolating people infected with HCV involves physical separation from others to limit direct or indirect transmission and includes a number of strategies during dialysis. The evidence for isolating people infected with HCV during haemodialysis is sparse with some inconsistencies. To evaluate the benefits and harms of isolation of HCV-infected patients during haemodialysis on the transmission of HCV to other patients. We searched the Cochrane Kidney and Transplant Specialised Register to 26 November 2015 through contact with the Information Specialist using search terms relevant to this review. We also searched the Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to 2015), Web of Science Conference Proceedings Citation Index-Science (CPCI-S, 1990 to 2015), ProQuest Dissertations & Theses Database (1990 to 2015), and Open Grey (1990 to 2015). We included randomised controlled trials (RCTs), quasi-RCTs and cluster RCTs evaluating the clinical benefits and harms of isolating HCV-infected patients during haemodialysis on the transmission of HCV to other patients. We considered incidence of dialysis-acquired HCV infection, all-cause mortality, and adverse effects associated with

    Chronically haemodialysed end-stage renal disease patients are at high risk of morbidity arising from complications of dialysis, the underlying pathology that has led to renal disease and the complex pathology of chronic kidney disease. Anaemia is commonplace and its origins are multifactorial, involving reduced renal erythropoietin production, accumulation of uremic toxins and an increase in erythrocyte fragility. Oxidative damage is a common risk factor in renal disease and its co-morbidities and is known to cause erythrocyte fragility. Therefore, we have investigated the hypothesis that specific erythrocyte membrane proteins are more oxidised in end-stage renal disease patients and that vitamin C supplementation can ameliorate membrane protein oxidation. Eleven patients and 15 control subjects were recruited to the study. Patients were supplemented with 2 × 500 mg vitamin C per day for 4 weeks. Erythrocyte membrane proteins were prepared pre- and post-vitamin C supplementation for determination of protein oxidation. Total protein carbonyls were reduced by vitamin C supplementation but not by dialysis when investigated by enzyme linked immunosorbent assay. Using a western blot to detect oxidised proteins, one protein band, later identified as containing ankyrin, was found to be oxidised in patients but not controls and was reduced significantly by 60% in all patients after dialysis and by 20% after vitamin C treatment pre-dialysis. Ankyrin oxidation analysis may be useful in a stratified medicines approach as a possible marker to identify requirements for intervention in dialysis patients.

    Chronic inflammation in haemodialysis (HD) patients indicates a poor prognosis. However, therapeutic approaches are limited. Hydrogen gas (H(2)) ameliorates oxidative and inflammatory injuries to organs in animal models. We developed an HD system using a dialysis solution with high levels of dissolved H(2) and examined the clinical effects. Dialysis solution with H(2) (average of 48 ppb) was produced by mixing dialysate concentrates and reverse osmosis water containing dissolved H(2) generated by a water electrolysis technique. Subjects comprised 21 stable patients on standard HD who were switched to the test HD for 6 months at three sessions a week. During the study period, no adverse clinical signs or symptoms were observed. A significant decrease in systolic blood pressure (SBP) before and after dialysis was observed during the study, and a significant number of patients achieved SBP <140 mmHg after HD (baseline, 21%; 6 months, 62%; P < 0.05). Changes in dialysis parameters were minimal, while significant decreases in levels of plasma monocyte chemoattractant protein 1 (P < 0.01) and myeloperoxidase (P < 0.05) were identified. Adding H(2) to haemodialysis solutions ameliorated inflammatory reactions and improved BP control. This system could offer a novel therapeutic option for control of uraemia.

    Full Text Available Hepatitis C virus (HCV infection is a global medical problem. The current standard of treatment consists of the combination of peginterferon plus ribavirin. This regimen eradicates HCV in 55% of cases. The immune response to HCV is an important determinant of disease evolution and can be influenced by various host factors. HLA class II may play an important role in immune response against HCV. The objective of the present study was to determine the distribution of HLA class II (DRB1 and DQB1 alleles, their association with chronic HCV infection and their response to interferon therapy. One hundred and two unrelated white Brazilian patients with chronic HCV infection, 52 responders (45 males and 7 females and 50 non-responders (43 males and 7 females to antiviral treatment, were included in the study. Healthy Brazilian bone marrow donors of Caucasian origin from the same geographic area constituted the control group (HLA-DRB1, N = 99 and HLA-DQB1, N = 222 individuals. HLA class II genotyping was performed using a low-resolution DRB1, DQB1 sequence-specific primer amplification. There were higher frequencies of HLA-DRB1*13 (26.5 vs 14.1% and HLA-DQB1*02 (52.9 vs 38.7% in patients compared with controls; however, these were not significantly different after P correction (Pc = 0.39 and Pc = 0.082, respectively. There was no significant difference between the phenotypic frequencies of HLA-DRB1 (17.3 vs 14.0% and HLA-DQB1 alleles in responder and non-responder HCV patients. The HLA-DRB1*07 allele was significantly more common in HCV patients (33.3 vs 12.1% than in controls (Pc = 0.0039, suggesting that the HLA-DRB1*07 allele is associated with chronic HCV infection.

    Full Text Available Background: The majority of haemodialysis (HD patients gain weight between dialysis sessions and thereby become volume overloaded, whereas peritoneal dialysis (PD is a more continuous technique. Cardiovascular mortality and hypertension is increased with both treatment modalities. We therefore wished to compare volume status in PD and HD to determine whether PD patients are chronically volume overloaded, as a risk factor for cardiovascular mortality. Study Design, Setting and Participants:We retrospectively audited 72 healthy HD patients and 115 healthy PD patients attending a university hospital dialysis centre for routine outpatient treatment, who had multi-frequency bioimpedance measurements of extracellular water to total body water (ECW/TBW. Results: The groups were well matched for age, sex, weight and ethnicity, PD patients had greater urine output [1,075 (485–1,613 vs. 42.5 (0–1,020 ml/day, p Conclusions: Overhydration is common in healthy stable PD outpatients, and ECW volumes in PD patients are not dissimilar to those of pre-dialysis HD patients. The role of chronic volume overload as a risk factor for cardiovascular disease needs further investigation.

    The purpose of this study was to evaluate the prevalence of taurodontism in patients with nonsyndromic cleft lip and palate (NSCLP) within a Brazilian population. The study was designed as an epidemiologic case-control single-center study. Three hundred eighty-eight patients were included: 88 had NSCLP, and 300 comprised the control group. The first and second permanent mandibular molars were included in this study. By using panoramic radiographs, taurodontism was categorized as mesotaurodontism, hypotaurodontism, and hypertaurodontism. Seventy patients (23.3%) from the control group and 36 patients (40.9%) from the case group presented taurodontism (P taurodontism, whereas in the case group with cleft lip and palate (CLP), 64 (18.2%) teeth showed dental anomalies (P taurodontic teeth presented hypotaurodontism, followed by mesotaurodontism, while hypertaurodontism was found in only two teeth. The probability of taurodontism in patients with cleft lip (CL) was 2.36 (P = .010) times higher compared with those with CLP, whereas the occurrence of taurodontism in patients with cleft palate (CP) was 3.15 (P = .002) times greater than in patients with CLP. The results from this study indicate a close relationship between taurodontism and NSCLP and the possibility of different cleft subphenotypes. Copyright © 2015 Elsevier Inc. All rights reserved.

    An ever-increasing number of patients have to undergo regular renal dialysis to compensate for acute or chronic renal failure. The adequacy of the treatment has a profound effect on patients’ morbidity and mortality. Therefore it is necessary to assess the delivered dialysis dose. For the quantification of the dialysis dose two parameters are most commonly used, namely the Kt/V value (normalised dose of dialysis) and the urea reduction rate, yet the prescribed dialysis dose often differs from...

  4. Detection of somatic mutations of the PIG-A gene in Brazilian patients with paroxysmal nocturnal hemoglobinuria

    Full Text Available Paroxysmal nocturnal hemoglobinuria (PNH is an acquired clonal syndrome characterized by intravascular hemolysis mediated by complement, thrombotic events and alterations in hematopoiesis. Basically, the molecular events which underlie the complexity of the syndrome consist of the absence of the glycosylphosphatidylinositol (GPI anchor as a consequence of somatic mutations in the PIG-A gene, located on the X chromosome. The GPI group is responsible for the attachment of many proteins to the cytoplasmic membrane. Two of them, CD55 and CD59, have a major role in the inhibition of the action of complement on the cellular membrane of blood cells. The absence of GPI biosynthesis can lead to PNH. Since mutations in the PIG-A gene are always present in patients with PNH, the aim of this study was to characterize the mutations in the PIG-A gene in Brazilian patients. The analysis of the PIG-A gene was performed using DNA samples derived from bone marrow and peripheral blood. Conformation-sensitive gel electrophoresis was used for screening the mutation and sequencing methods were used to identify the mutations. Molecular analysis permitted the identification of three point mutations in three patients: one G->A transition in the 5' portion of the second intron, one T->A substitution in the second base of codon 430 (Leu430->stop, and one deletion deltaA in the third base of codon 63. This study represents the first description of mutations in the PIG-A gene in a Brazilian population.

    Clinical measurement. To translate and culturally adapt the Lower Extremity Functional Scale (LEFS) into a Brazilian Portuguese version, and to test the construct and content validity and reliability of this version in patients with knee injuries. There is no Brazilian Portuguese version of an instrument to assess the function of the lower extremity after orthopaedic injury. The translation of the original English version of the LEFS into a Brazilian Portuguese version was accomplished using standard guidelines and tested in 31 patients with knee injuries. Subsequently, 87 patients with a variety of knee disorders completed the Brazilian Portuguese LEFS, the Medical Outcomes Study 36-Item Short-Form Health Survey, the Western Ontario and McMaster Universities Osteoarthritis Index, and the International Knee Documentation Committee Subjective Knee Evaluation Form and a visual analog scale for pain. All patients were retested within 2 days to determine reliability of these measures. Validation was assessed by determining the level of association between the Brazilian Portuguese LEFS and the other outcome measures. Reliability was documented by calculating internal consistency, test-retest reliability, and standard error of measurement. The Brazilian Portuguese LEFS had a high level of association with the physical component of the Medical Outcomes Study 36-Item Short-Form Health Survey (r = 0.82), the Western Ontario and McMaster Universities Osteoarthritis Index (r = 0.87), the International Knee Documentation Committee Subjective Knee Evaluation Form (r = 0.82), and the pain visual analog scale (r = -0.60) (all, PPortuguese LEFS had a low level of association with the mental component of the Medical Outcomes Study 36-Item Short-Form Health Survey (r = 0.38, PPortuguese version of the LEFS were high. The standard error of measurement was low (3.6) and the agreement was considered high, demonstrated by the small differences between test and retest and the narrow

    Patients with metastatic non-small cell lung cancer are deemed incurable, but they may derive some benefit from systemic palliative chemotherapy. Recently, with the introduction of epidermal growth factor receptor (EGFR) antagonists such as gefitinib (Iressa), an effective and less toxic option is now available for the treatment of such patients. To assess the activity and toxicity of gefitinib in a group of Brazilian patients. Prospective, open label, non-randomized and non-controlled. Clínica de Oncologia e Hematologia (CLIOH), São Paulo, Brazil. From June 2002 to April 2003 we treated five patients with metastatic previously-treated non-small cell lung cancer (median of two previous chemotherapy regimens), using gefitinib at a dose of 250 mg orally on a daily basis, within a compassionate protocol sponsored by AstraZeneca. The patients' median age was 65 years and two of them were male. Three had a performance status of 1, one of 2 and one of 3, on the ECOG (Eastern Cooperative Oncology Group) scale. We observed skin rash in two patients, diarrhea in three and arthralgia in two. One patient had a partial response and another had stabilization of her disease, as measured via imaging studies (which have lasted for more than 11 and 4 months, respectively), which were accompanied by significant decrease in tumor markers, whereas three patients worsened during treatment. New options of chemotherapy agents with favorable toxicity profiles are urgently needed for the treatment of metastatic non-small lung cancer patients who usually have short life expectancies. In our small series of five patients, we observed stabilization of the disease in two of them and the skin and gastrointestinal reactions often described in the literature in all of them. Two had arthralgia, not reported before. We concluded that gefitinib is an important addition to the therapeutic armamentarium for patients with metastatic non-small cell lung cancer.

    This study aimed to compare plasma levels of total homocysteine (tHcy) in different arterial events as well as to investigate an association between homocysteine levels and C677T polymorphism in Brazilian patients. A total of 145 subjects were enrolled in this study including 43 patients with coronary arterial disease (CAD), 21 with ischemic stroke (IS), 44 with peripheral arterial obstructive disease (PAOD) and 37 control subjects. A preliminary analysis showed significant difference for tHcy plasma levels between patients with CAD (P = 0.003) or PAOD (P = 0.03) compared to controls. However, after adjustment for sex, age, total cholesterol, LDL, diabetes, tabagism or C677T polymorphism, no significant differences were detected in tHcy levels among patients groups and controls. No significant correlation was demonstrated for C677T polymorphism and homocysteine levels. These results indicate that increased Hcy levels may not be considered an independent risk factor for atherothrombotic diseases in Brazilian patients.

    Burnout, psychological distress and job satisfaction experienced by healthcare workers in general are well documented in the literature; however, there is a paucity of research that focuses on the experiences of haemodialysis staff. The study investigates burnout, psychological distress and job satisfaction in a sample of 50 haemodialysis staff from two units in one National Health Service (NHS) trust in London, England, using the Maslach Burnout Inventory (MBI), General Health Questionnaire (GHQ-12) and the Minnesota Satisfaction Questionnaire (MSQ). The majority of staff did not experience burnout or psychological distress and were satisfied with their jobs. However, some participants had low personal accomplishment and were dissatisfied with certain areas of their jobs. Age and length of haemodialysis experience were associated with burnout, job satisfaction and psychological distress. Older staff and staff with a greater length of service in haemodialysis have higher levels of burnout, psychological distress and job dissatisfaction.

The study group with 154 patients with PD, and the control group included 140 individuals without PD. The genotyping of SNCA-A53T was performed by PCR/RFLP. Significance level was p < 0.05.Results Among all patients, 37 (24% had FPD and 117 (75.9% had SPD. The absence of SNCA-A53T mutation was observed in all individuals.Conclusion SPD is notably observed in patients. However, the SNCA-A53T mutation was absent in all individuals, which does not differ controls from patients. This fact should be confirmed in a Brazilian study case with a more numerous and older population.

    To evaluate the presence of behavioral inhibition and anxiety disorders during childhood in Brazilian adult patients with panic disorder and social anxiety disorder compared to a control group. Fifty patients with panic disorder, 50 patients with social anxiety disorder, and 50 control subjects were included in the study. To assess the history of childhood anxiety, the Schedule for Affective Disorders and Schizophrenia for School Age Children, Epidemiologic Version (K-SADS-E), and the Diagnostic Interview for Children and Adolescents-Parent Version (DICA-P) were used. The presence of behavioral inhibition in childhood was assessed by the self-reported scale of Behavioral Inhibition Retrospective Version (RSRI-30). Patients showed significantly higher prevalence of anxiety disorders and behavioral inhibition in childhood compared to the control group. Patients with social anxiety disorder also showed significantly higher rates of avoidance disorder (46% vs. 18%, p = 0.005), social anxiety disorder (60% vs. 26%, p = 0.001), presence of at least one anxiety disorder (82% vs. 56%, p = 0.009) and global behavioral inhibition (2.89 +/- 0.61 vs. 2.46 +/- 0.61, p panic disorder. Our data are in accordance to the literature and corroborates the theory of an anxiety diathesis, suggesting that a history of anxiety disorders in childhood is associated with an anxiety disorder diagnosis, mainly social anxiety disorder, in adulthood.

    Leprosy outcome is a complex trait and the host-pathogen-environment interaction defines the emergence of the disease. Host genetic risk factors have been successfully associated to leprosy. The 10p13 chromosomal region was linked to leprosy in familial studies and GATA3 gene is a strong candidate to be part of this association. Here, we tested tag single nucleotide polymorphisms at GATA3 in two case-control samples from Brazil comprising a total of 1633 individuals using stepwise strategy. The A allele of rs10905284 marker was associated with leprosy resistance. Then, a functional analysis was conducted and showed that individuals carrying AA genotype express higher levels of GATA-3 protein in lymphocytes. So, we confirmed that the rs10905284 is a locus associated to leprosy and influences the levels of this transcription factor in the Brazilian population. Copyright © 2016 Elsevier B.V.

    Full Text Available CONTEXT: Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. OBJECTIVES: To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. METHOD: This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. RESULTS: During the period analyzed, 209 procedures were performed on 170 patients. Postope-rative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. CONCLUSION: Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients

  17. Uremic Toxins and Lipases in Haemodialysis: A Process of Repeated Metabolic Starvation

    Directory of Open Access Journals (Sweden)

    Bernd Stegmayr

    2014-04-01

    Full Text Available Severe kidney disease results in retention of uremic toxins that inhibit key enzymes for lipid breakdown such as lipoprotein lipase (LPL and hepatic lipase (HL. For patients in haemodialysis (HD and peritoneal dialysis (PD the LPL activity is only about half of that of age and gender matched controls. Angiopoietin, like protein 3 and 4, accumulate in the uremic patients. These factors, therefore, can be considered as uremic toxins. In animal experiments it has been shown that these factors inhibit the LPL activity. To avoid clotting of the dialysis circuit during HD, anticoagulation such as heparin or low molecular weight heparin are added to the patient. Such administration will cause a prompt release of the LPL and HL from its binding sites at the endothelial surface. The liver rapidly degrades the release plasma compound of LPL and HL. This results in a lack of enzyme to degrade triglycerides during the later part of the HD and for another 3–4 h. PD patients have a similar baseline level of lipases but are not exposed to the negative effect of anticoagulation.

Glycemic control, prevalence of cardiovascular risk factors, screening for chronic complications and the frequency that the recommended treatment goals were met using the American Diabetes Association guidelines were evaluated. Methods This was a cross-sectional, multicenter study conducted from December 2008 to December 2010 in 28 secondary and tertiary care public clinics in 20 Brazilian cities in north/northeast, mid-west, southeast and south regions. The data were obtained from 3,591 patients (56.0% females and 57.1% Caucasians aged 21.2 ± 11.7 years with a disease duration of 9.6 ± 8.1 years ( Results Overall, 18.4% patients had HbA1c levels Conclusions A majority of patients, mainly in the north/northeast and mid-west regions, did not meet metabolic control goals and were not screened for diabetes-related chronic complications. These results should guide governmental health policy decisions, specific to each geographic region, to improve diabetes care and decrease the negative impact diabetes has on the public health system.

We evaluated whether biofilm formation in the hydraulic circuit of a purposely contaminated haemodialysis monitor would modify the efficacy of different disinfection modalities against bacteria and endotoxin concentrations. A water-borne Pseudomonas aeruginosa (109) suspension was recirculated for 1 h and was left standing for 72 h (stationary phase) in the hydraulic circuit of the monitor. The monitor was then washed and disinfected by different physical (heat, 85 degrees C) or chemical (hypochlorite or peracetic acid) disinfection modalities (protocol A). In protocol B, the bacterial suspension was also recirculated for 1 h, but the monitor was then immediately washed and disinfected by different chemical disinfection modalities (hypochlorite or peracetic acid). Biofilm formation was revealed by scanning and confocal laser electron microscopy after the stationary phase (protocol A), but was absent when the monitor was immediately washed and disinfected (protocol B). In the presence of biofilm (protocol A), heat in association with citric acid was the most effective modality for reducing both colony forming units and endotoxin concentrations, whereas heat by itself was the least effective method of disinfection. Dwelling (60 h) with diluted peracetic acid completely prevented the formation of biofilm. In the absence of biofilm (protocol B), chemical disinfection proved to be effective against both colony forming units and endotoxin concentrations. We found that biofilm formation may markedly reduce the efficacy of presently available disinfection modalities. Therefore, different disinfection modalities and the combined action of descaling (by citric acid) and disinfection (physical/chemical agents) should be used periodically in haemodialysis monitors. In addition, dwelling with diluted peracetic acid should be adopted whenever monitors are not in use.

    Protein-adsorptive properties are a key feature of membranes used for haemodialysis treatment. Protein adsorption is vital to the biocompatibility of a membrane material and influences membrane's performance. The object of the present study is to investigate membrane biocompatibility by correlating the adsorbed proteome repertoire with chemical feature of the membrane surfaces. Dialyzers composed of either cellulose triacetate (Sureflux 50 L, effective surface area 0.5 m(2); Nipro Corporation, Japan) or the polysulfone-based helixone (FX40, effective surface area 0.4 m(2); Fresenius Medical Care AG, Germany) materials were employed to develop an ex vivo apparatus to study protein adsorption. Adsorbed proteins were eluted by a strong chaotropic buffer condition and investigated by a proteomic approach. The profiling strategy was based on 2D-electrophoresis separation of desorbed protein coupled to MALDI-TOF/TOF analysis. The total protein adsorption was not significantly different between the two materials. An average of 179 protein spots was visualised for helixone membranes while a map of retained proteins of cellulose triacetate membranes was made up of 239 protein spots. The cellulose triacetate material showed a higher binding capacity for albumin and apolipoprotein. In fact, a number of different protein spots belonging to the gene transcript of albumin were visible in the cellulose triacetate map. In contrast, helixone bound only a small proportion of albumin, while proved to be particularly active in retaining protein associated with the coagulation cascade, such as the fibrinogen isoforms. Our data indicate that proteomic techniques are a useful approach for the investigation of proteins surface-adsorbed onto haemodialysis membranes, and may provide a molecular base for the interpretation of the efficacy and safety of anticoagulation treatment during renal replacement therapy.

    Full Text Available In most mammals, male development is triggered by the transient expression of the SRY gene, which initiates a cascade of gene interactions ultimately leading to the formation of a testis from the indifferent fetal gonad. Mutation studies have identified several genes essential for early gonadal development. We report here a molecular study of the SRY, DAX1, SF1 and WNT4 genes, mainly involved in sexual determination, in Brazilian 46,XX and 46,XY sex-reversed patients. The group of 46,XX sex-reversed patients consisted of thirteen 46,XX true hermaphrodites and four 46,XX males, and was examined for the presence of the SRY gene and for the loss of function (inactivating mutations and deletions of DAX1 and WNT4 genes. In the second group consisting of thirty-three 46,XY sex-reversed patients we investigated the presence of inactivating mutations in the SRY and SF1 genes as well as the overexpression (duplication of the DAX1 and WNT4 genes. The SRY gene was present in two 46,XX male patients and in none of the true hermaphrodites. Only one mutation, located outside homeobox domain of the 5' region of the HMG box of SRY (S18N, was identified in a patient with 46,XY sex reversal. A novel 8-bp microdeletion of the SF1 gene was identified in a 46,XY sex-reversed patient without adrenal insufficiency. The dosage of DAX1 and WNT4 was normal in the sex-reversed patients studied. We conclude that these genes are rarely involved in the etiology of male gonadal development in sex-reversed patients, a fact suggesting the presence of other genes in the sex determination cascade.

    Full Text Available The hypothesis of the role of iron overload associated with HFE gene mutations in the pathogenesis of nonalcoholic steatohepatitis (NASH has been raised in recent years. In the present study, biochemical and histopathological evidence of iron overload and HFE mutations was investigated in NASH patients. Thirty-two NASH patients, 19 females (59%, average 49.2 years, 72% Caucasians, 12% Mulattoes and 12% Asians, were submitted to serum aminotransferase and iron profile determinations. Liver biopsies were analyzed for necroinflammatory activity, architectural damage and iron deposition. In 31 of the patients, C282Y and H63D mutations were tested by PCR-RFLP. Alanine aminotransferase levels were increased in 30 patients, 2.42 ± 1.12 times the upper normal limit on average. Serum iron concentration, transferrin saturation and ferritin averages were 99.4 ± 31.3 g/dl, 33.1 ± 12.7% and 219.8 ± 163.8 µg/dl, respectively, corresponding to normal values in 93.5, 68.7 and 78.1% of the patients. Hepatic siderosis was observed in three patients and was not associated with architectural damage (P = 0.53 or with necroinflammatory activity (P = 0.27. The allelic frequencies (N = 31 found were 1.6 and 14.1% for C282Y and H63D, respectively, which were compatible with those described for the local population. In conclusion, no evidence of an association of hepatic iron overload and HFE mutations with NASH was found. Brazilian NASH patients comprise a heterogeneous group with many associated conditions such as hyperinsulinism, environmental hepatotoxin exposure and drugs, but not hepatic iron overload, and their disease susceptibility could be related to genetic and environmental features other than HFE mutations.

    The well-being of patients undergoing chemotherapy treatment for colorectal cancer (CRC) is affected by psychological effects associated with cancer treatment. However, little is known about the impact of these psychological factors in Brazilian patients with CRC. The aim of this study was to determine whether perceived stress, social support, and resilience are associated with quality of life in urban Brazilian patients receiving chemotherapy treatment for CRC. This was a cross-sectional study conducted with 144 Brazilian CRC patients in an ambulatory oncology clinic. The participants completed 5 questionnaires: Demographics, Perceived Stress Scale 14, Social Support Satisfaction Scale, Resilience Scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaires (C30 and CR29). Confirmatory factor analysis modeling and Cronbach's α were used to examine construct validity and internal consistency. We used the MPlus 3.0 to construct and validate the structural model. There was a moderate and positive effect of resilience on the physical, social, and emotional aspects of quality of life. Social support had a strong and positive direct effect on quality of life (ie, social, physical, social, and emotional). Social support had a negative effect on stress perception. Resilience was also negatively related to stress perception. Family support and professional social support are important factors for Brazilian CRC patients. Resilience is an important ally for patients. It is important for nurses to consider this when developing educational and psychological interventional strategies to reduce stress and ultimately improve quality of life in this population. Psychological factors that improve quality of life should be evaluated in patients undergoing treatment for cancer.

    Full Text Available A clinical study of Brazilian patients with neurofibromatosis type 1 (NF1 was performed in a multidisciplinary Neurofibromatosis Program called CEPAN (Center of Research and Service in Neurofibromatosis. Among 55 patients (60% females, 40% males who met the NIH criteria for the diagnosis of NF1, 98% had more than six café-au-lait patches, 94.5% had axillary freckling, 45% had inguinal freckling, and 87.5% had Lisch nodules. Cutaneous neurofibromas were observed in 96%, and 40% presented plexiform neurofibromas. A positive family history of NF1 was found in 60%, and mental retardation occurred in 35%. Some degree of scoliosis was noted in 49%, 51% had macrocephaly, 40% had short stature, 76% had learning difficulties, and 2% had optic gliomas. Unexpectedly high frequencies of plexiform neurofibromas, mental retardation, learning difficulties, and scoliosis were observed, probably reflecting the detailed clinical analysis methods adopted by the Neurofibromatosis Program. These same patients were screened for mutations in the GAP-related domain/GRD (exons 20-27a by single-strand conformation polymorphism. Four different mutations (Q1189X, 3525-3526delAA, E1356G, c.4111-1G>A and four polymorphisms (c.3315-27G>A, V1146I, V1317A, c.4514+11C>G were identified. These data were recently published.

    Studies in patients with diabetes have shown that the guided self determination (GSD) method effectively improves patients' glycaemia control and life skills. As a pilot study in 2011 showed promising results of using parts of GSD adjusted to patients on haemodialysis (HD), we decided to develop and test a full-scale GSD for this patient group (GSD-HD). To study how a full-scale GSD-HD influenced the quality of relatedness between the patient and the GSD-HD nurse and the patients' ability to live well with end stage renal disease (ESRD). GSD-HD was developed through participatory research and evaluated qualitatively at five dialysis units in Denmark involving 31 patients and 16 nurses. The intervention lasted four months and comprised six sessions. Data consisting of semi-structured interviews with 13 patients were analysed using a mix of inductive and deductive thematic analysis. A process of developing life skills was clearly identified in the changes accomplished by all 13 participants going through the GSD-HD intervention. Six themes showed that the changes involved the patients personally, their relationships with healthcare professionals and relatives and their self-management of ESRD: Deeper and more meaningful relationships, self-exploration of self-selected challenges, self-understanding as a condition for meaningful knowledge, ability to act in a self-determined way, feedback from action that accords with daily life skills and decision-making from professional to share. The positive changes identified in this qualitative evaluation are promising and indicate that GSD-HD has a potential worthwhile to be tested further among patients with ESRD. © 2015 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Full Text Available The human beta defensin 1 (hBD-1 antimicrobial peptide is a member of the innate immune system known to act in the first line of defence against microorganisms, including viruses such as human papillomavirus (HPV. In this study, five functional polymorphisms (namely g-52G>A, g-44C>G and g-20G>A in the 5’UTR and c.*5G>A and c.*87A>G in the 3’UTR in the DEFB1 gene encoding for hBD-1 were analysed to investigate the possible involvement of these genetic variants in susceptibility to HPV infection and in the development of HPV-associated lesions in a population of Brazilian women. The DEFB1 g-52G>A and c.*5G>A single-nucleotide polymorphisms (SNPs and the GCAAA haplotype showed associations with HPV-negative status; in particular, the c.*5G>A SNP was significantly associated after multiple test corrections. These findings suggest a possible role for the constitutively expressed beta defensin-1 peptide as a natural defence against HPV in the genital tract mucosa.

    Cervical cancer is the fourth most common cancer among women, and ∼70-80% of these cancers are associated with two human papillomavirus types: HPV16 and HPV18. Several studies have reported that intra-type diversity is associated with the progression of infection to invasive cancer. Herein, we report the genetic diversity of HPV16 and HPV18 in a cohort of 594 Brazilian women with invasive cervical cancer and describe the prevalence of lineages and intra-type diversity prior to the implementation of the public immunization program in Brazil. HPV detection and genotyping were performed using PCR, PGMY/GP primers, and DNA extracted from fresh tumors. The HPV16 (378 women) and HPV18 (80 women) lineages were identified by PCR and sequencing of the LCR and E6 fragments, followed by SNV comparison and phylogenetic analysis. In our cohort, was found a higher frequency of the lineage A (in 217 women), followed by lineage D (in 97 women) and lineages B and C (in 10 women each) for HPV16; and a higher frequency of lineage A (in 56 women) followed by lineage B (in 15 women) in HPV18. The genetic diversity of HPV16 indicated a recent expansion of specific variants or a selective advantage that is associated with invasive cancer; this pattern was not observed for HPV18. © 2016 Wiley Periodicals, Inc.

    Autosomal dominant cerebellar ataxia, deafness and narcolepsy (ADCA-DN) is caused by DNMT1 mutations. Diagnosing the syndrome can be difficult, as all clinical features may not be present at onset, HLA-DQB1*06:02 is often negative, and sporadic cases occur. We report on clinical and genetic findings in a 31-year-old woman with cerebellar ataxia, deafness, and narcolepsy, and discuss diagnostic challenges. Clinical and genetic investigation in a patient and family members. Ataxia clinic, São Paulo, Brazil. One patient and her family members. N/A. Narcolepsy was supported by polysomnographic and multiple sleep latency testing. HLA-DQB1*06:02 was positive. CSF hypocretin-1 was 191 pg/mL (normal values > 200 pg/mL). Mild brain atrophy was observed on MRI, with cerebellar involvement. The patient, her asymptomatic mother, and 3 siblings gave blood samples for genetic analysis. DNMT1 exons 20 and 21 were sequenced. Haplotyping of polymorphic markers surrounding the mutation was performed. The proband had a novel DNMT1 mutation in exon 21, p.Cys596Arg, c.1786T > C. All 4 parental haplotypes could be characterized in asymptomatic siblings without the mutation, indicating that the mutation is de novo in the patient. The Brazilian patient reported here further adds to the worldwide distribution of ADCA-DN. The mutation is novel, and illustrates a sporadic case with de novo mutation. We believe that many more cases with this syndrome are likely to be diagnosed in the near future, mandating knowledge of this condition and consideration of the diagnosis.

    Full Text Available INTRODUCTION: Prospective studies have shown that the course of bipolar disorder (BD is characterized by the persistence of symptoms, predominantly depression, along most of the time. However, to our knowledge, no studies in Latin America have investigated it. OBJECTIVES: To replicate international studies using a Brazilian sample to prospectively analyze treatment outcomes in the first year and to determine potential chronicity factors. METHODS: We followed up 102 patients with BD for 12 months and evaluated the number of months with affective episodes and the intensity of manic and depressive symptoms using the Young Mania Rating Scale (YMRS and the Hamilton Depression Scale (HAM-D17. Sociodemographic and retrospective clinical data were examined to determine possible predictors of outcome. RESULTS: Almost 50% of the patients had symptoms about half of the time, and there was a predominance of depressive episodes. Disease duration and number of depressive episodes were predictors of chronicity. Depressive polarity of the first episode and a higher number of depressive episodes predicted the occurrence of new depressive episodes. CONCLUSION: In general, BD outcome seems to be poor in the first year of monitoring, despite adequate treatment. There is a predominance of depressive symptoms, and previous depressive episodes are a predictor of new depressive episodes and worse outcome.

    Full Text Available Maintenance of proper oral hygiene by dental plaque elimination is one of the most important factors affecting the healing process in postoperative oral wounds. Propolis is a substance produced by bees. Ethanolic extract of propolis has bactericidal, fungicidal, anti-inflammatory, and antioxidative properties. Moreover, it can scavenge free radicals. The purpose of this paper is to demonstrate the efficacy of a gel containing 3% of ethanolic extract of Brazilian green propolis (EEP-B when used for maintaining oral hygiene in patients with postoperative oral mucosal wounds. The hygiene was assessed using API, OHI, and SBI followed by microbiological examinations. The patients were divided into two groups. Group 1 consisted of those who used a gel containing EEP-B for oral hygiene, and group 2 consisted of those who used a gel without EEP-B. Although improved oral hygiene was noted in both groups, the improvement was markedly greater in the group using gel containing EEP-B. Summing up the results of microbiological examinations, EEP-B has beneficial effect on mouth microflora in postoperative period. Propolis preparations used for oral hygiene allow eliminating microorganisms of pathogenic character and physiological flora microorganisms considered as being opportunistic, with no harmful influence on physiological microflora in oral ecosystem.

    Full Text Available CONTEXT AND OBJECTIVE: Mycobacterium avium subsp. paratuberculosis (MAP has attracted the interest of researchers because of similarities between paratuberculosis and Crohn's disease (CD. The aim of this study was to evaluate the frequency of MAP through cultures, histology and polymerase chain reaction (PCR on intestinal biopsies from Brazilian CD patients. Quantitative real time PCR (qRT-PCR was performed on positive samples. DESIGN AND SETTING: Analytical cross-sectional study with control group at two federal universities. METHODS: Fresh samples were collected from 25 patients; five with CD, eight with ulcerative colitis (UC and 12 controls with non-inflammatory bowel disease (nIBD. Formalin-fixed paraffin-embedded (FFPE samples from 143 patients were also collected: 44 CD, 49 UC and 56 nIBD. RESULTS: None of the fresh samples was positive for MAP. Five FFPE samples (one CD, two UC and two nIBD and three fresh samples (one in each group were positive through IS900-PCR. qRT-PCR was performed on these eight samples. Among the FFPE samples, there were 192.12 copies/μl in the CD group, 72.28 copies/μl in UC and 81.43 copies/μl in nIBD. Among the fresh samples, there were 432.99 copies/μl, 167.92 copies/μl and 249.73 copies/μl in the CD, UC and nIBD groups, respectively. The highest bacterial load was in the CD group. CONCLUSION: This study does not provide evidence for a role of MAP in the etiology of CD, although MAP DNA was detected in all three patient groups. This is the first report of MAP presence in human intestinal biopsies in Brazil.

    With improved dialysis survival there are increasing numbers of patients who have exhausted definitive access options due to central venous stenosis and are maintaining dialysis on a central venous catheter. The Hemodialysis Reliable Outflow (HeRO) allows an alternative by providing a definitive access solution. The aim of this study is to systematically review the published outcomes of the HeRO graft and discuss the role in complex haemodialysis patients. Electronic databases were searched for studies assessing the use of the HeRO graft for dialysis in accordance with PRISMA published up to December 31 2014. The primary outcomes for this study were 1-year primary and secondary patency rates. Secondary outcomes were rates of dialysis access associated steal syndrome, HeRO-related bacteraemia rates and rates of interventions. Following strict inclusion/exclusion criteria, eight studies including 409 patients were included in our review. Primary and secondary pooled patency rates in this complex cohort of dialysis patients were found to be 21.9% (9.6-37.2%) and 59.4% (39.4-78%). The rate of dialysis access associated steal syndrome was low at 6.3% (1-14.7%) as was the range of HeRO-related bacteraemia (0.13-0.7 events per 1000 days). This literature review shows that the HeRO graft is an acceptable option for complex dialysis patients who are catheter dependent. Owing to device availability, published data are predominantly North American and further longer-term studies in other populations may be necessary. In this challenging patient group, randomized controlled trials are required to allow comparisons with alternative access options. Copyright © 2015 European Society for Vascular Surgery.

    Most haemodialysis (HD) centres use anti-hypertensive drugs for the management of hypertension, whereas some centres apply dietary salt restriction strategy. In this retrospective cross-sectional study, we assessed the effectiveness and cardiac consequences of these two strategies. We enrolled all patients from two dialysis centres, who had been on a standard HD programme at the same centre for at least 1 year. All patients underwent echocardiographic evaluation. Clinical data were obtained from patients' charts. Centre A (n = 190) practiced 'salt restriction' strategy and Centre B (n = 204) practiced anti-hypertensive-based strategy. Salt restriction was defined as managing high blood pressure (BP) via lowering dry weight by strict salt restriction and insistent ultrafiltration without using anti-hypertensive drugs. There was no difference regarding age, gender, diabetes, history of cardiovascular disease and efficiency of dialysis between centres. Antihypertensive drugs were used in 7% of the patients in Centre A and 42% in Centre B (P < 0.01); interdialytic weight gain was significantly lower in Centre A (2.29 +/- 0.83 kgversus 3.31 +/- 1.12 kg, P < 0.001). Mean systolic and diastolic blood pressures were similar in the two centres. However, Centre A had lower left ventricular (LV) mass (indexed for height(2.7): 59 +/- 16 versus 74 +/- 27 g/m(2.7), P < 0.0001). The frequency of LV hypertrophy was lower in Centre A (74% versus 88%, P < 0.001). Diastolic and systolic functions
