Abstract
Malnutrition is a common condition in patients undergoing hemodialysis (HD), and it is associated with increased morbidity and mortality. The main objective of the study was to evaluate the nutritional status of patients on maintenance HD. After applying eligibility criteria, 141 HD patients attending major governmental dialysis centers were randomly recruited in this cross-sectional study and assessed for nutritional status using the Patient-Generated Subjective Global Assessment (PG-SGA) tool. The PG-SGA categorizes patients as well-nourished, moderately malnourished, and severely malnourished. Different anthropometric measurements, laboratory investigations, blood pressure measurements, and 24-h dietary recall were collected from each patient. According to PG- SGA results, 78% of patients were moderately malnourished and 22% of patients were severely malnourished. The mean body mass index was 27.8 kg/m2, and 5.7% of patients were underweight. There were significant differences in the mid-upper arm muscle circumference (P = 0.020) between the PG-SGA groups. The total energy and protein intake were significantly (P <0.001) less than the recommended dietary intake by 1268.9 kcal and 41.4 g, respectively. The albumin level in 37.6% of patients was less than the normal level, and the results indicated that there were significant differences in serum iron (P = 0.022) between the moderately and severely malnourished patients. The results of this study indicated that all HD patients were suffering from different degrees of malnutrition and, unfortunately, most of their energy and nutrient intake was far less than the requirements, which might be the reason why they face nutritional and health risks.

Abstract
Protein-energy wasting (PEW) is a major risk for morbidity and mortality in hemodialysis (HD) patients. The change in the concentration of dehydroepiandrosterone sulfate (DHEA-S) may play a role in PEW. The aim of this work was to study the possible relationship between serum DHEA-S levels and various nutritional and inflammatory parameters in a cohort of HD patients. In total, 78 HD patients (47 males and 31 females) were included in this crosssectional observational study. In addition to taking their history, clinical examinations, and routine laboratory investigations, the nutritional status was assessed, and their serum DHEA-S was measured. Nutritional status was assessed by anthropometric measures, bioelectrical impedance analysis, malnutrition inflammation scores, and subjective global assessments. A diagnosis of malnutrition was made based on the recommendations of the International Society of Renal Nutrition and Metabolism. The relationship between DHEA-S and various nutritional parameters was analyzed. Eighteen patients (23.1%) suffered from PEW. Those with PEW had a longer duration of HD (P = 0.04), and lower serum levels of creatinine (P = 0.003), hemoglobin (P = 0.01), albumin (P <0.0001), cholesterol (P = 0.02), and DHEA-S (P = 0.01). Among the variables, serum DHEA-S levels were significant predictors of PEW in this cohort (odds ratio: 0.976; 95% confidence interval: 0.954-1.0; P = 0.04). PEW is frequently encountered in HD patients. Decreased serum DHEA-S levels were associated with PEW in male HD patients. Further studies are needed to assess the effect of hormone supplementation on this serious disorder in HD patients.

Abstract
OBJECTIVES The association of malnutrition with chronic kidney disease (CKD) is well established. However, there is a paucity of studies of the effect of malnutrition risk (MR) on kidney function decline among older persons who do not have end-stage or dialyzable CKD. This study aimed to examine the association between MR status and kidney function, and future risks of kidney function decline and CKD progression in community-dwelling older adults. DESIGN AND METHODS Nutrition Screening Initiative's DETERMINE Your Nutritional Health Checklist and estimated glomerular filtration rate (eGFR) were assessed at baseline among 5,122 participants free of end-stage renal failure or dialyzed CKD in the Singapore Longitudinal Aging Studies (SLAS-1 and SLAS-2). Follow-up eGFR was assessed in a subcohort of SLAS-2 participants without CKD (eGFR > 60 mL/min/1.73 m2) at baseline (N = 786) who were followed up at 3-5 years. RESULTS In baseline cross-sectional analyses adjusting for other risk factors, low, moderate, and high MR was significantly associated with decreasing eGFR coefficients of -1.5, -3.3, and -5.0 mL/min/1.73 m2 respectively, and increasing CKD odds ratios of 1.81, 2.18, and 3.11 respectively. In longitudinal analysis, low, moderate, and high MR was significantly associated with increased risk of eGFR (>25%) decline (odds ratio of 2.37, 3.34, and 2.18 respectively). CONCLUSIONS Among older adults without advanced kidney disease, MR is associated with poor kidney function and increased risk of kidney function decline and CKD. Preventive interventions to modify MR may help to reduce the deterioration of renal function in older people.

Abstract
BACKGROUND Research indicates that cachexia is common among persons with chronic illnesses and is associated with increased morbidity and mortality. However, there continues to be an absence of a uniformed disease-specific definition for cachexia in chronic kidney disease (CKD) patient populations. OBJECTIVE The primary objective was to identify cachexia in patients receiving haemodialysis (HD) using a generic definition and then follow up on these patients for 12 months. METHOD This was a longitudinal study of adult chronic HD patients attending two hospital HD units in the UK. Multiple measures relevant to cachexia, including body mass index (BMI), muscle mass [mid-upper arm muscle circumference (MUAMC)], handgrip strength (HGS), fatigue [Functional Assessment of Chronic Illness Therapy (FACIT)], appetite [Functional Assessment of Anorexia/Cachexia Therapy (FAACT)] and biomarkers [C-reactive protein (CRP), serum albumin, haemoglobin and erythropoietin resistance index (ERI)] were recorded. Baseline analysis included group differences analysed using an independent t-test, dichotomized values using the χ2 test and prevalence were reported using the Statistical Package for the Social Sciences 24 (IBM, Armonk, NY, USA). Longitudinal analysis was conducted using repeated measures analysis. RESULTS A total of 106 patients (30 females and 76 males) were recruited with a mean age of 67.6 years [standard deviation (SD) 13.18] and dialysis vintage of 4.92 years (SD 6.12). At baseline, 17 patients were identified as cachectic, having had reported weight loss (e.g. >5% for >6 months) or BMI <20 kg/m2 and three or more clinical characteristics of cachexia. Seventy patients were available for analysis at 12 months (11 cachectic versus 59 not cachectic). FAACT and urea reduction ratio statistically distinguished cachectic patients (P = 0.001). However, measures of weight, BMI, MUAMC, HGS, CRP, ERI and FACIT tended to worsen in cachectic patients. CONCLUSION Globally, cachexia is a severe but frequently underrecognized problem. This is the first study to apply the defined characteristics of cachexia to a representative sample of patients receiving HD. Further, more extensive studies are required to establish a phenotype of cachexia in advanced CKD.

Abstract
Proper nutrition may reverse the malnutrition and can modulate renal function in hemodialysis patients. In majority of the dialysis units in India, nutritional advice is given by health professionals working in dialysis. We compared the impact of dietary counseling by a renal dietitian, on nutritional status with that by health professionals working in dialysis units in patients undergoing maintenance hemodialysis. Nutritional assessments were made using subjective global assessment (SGA) scale, which combines assessment of intake, physical findings, and functional status. Two hundred and seventy-seven patients undergoing hemodialysis from two renal care units in Nellore, Andhra Pradesh, South India, were enrolled (138 patients in control group, 139 in experimental group). In the experimental group, patients were given repeated dietary counseling by a renal dietician, whereas control group patients were provided with the necessary nutritional information by another health professional. Detailed nutritional, biochemical, and SGA assessment were done on all of them at the beginning and completion of study after 6 months. Patients were categorized as well-nourished (WN) (SGA = 1–14), mild to moderate malnourishment (MMM) (SGA = 15–35), and severe malnutrition (SM) (SGA = 36–49). In the present study, the overall malnutrition rate at baseline was 95.3%, and it dropped down to 91.7% after 6 months after nutritional counseling. In the experimental group, malnutrition status decreased from 97.2% to 89.8%, whereas in the control group, malnutrition situation remained same. Compared to baseline, in the control group, there was no improvement in the WN group. However, a shift has been observed from MMM group to SM group suggesting more number of patients are becoming malnourished. Contrarily, in the experimental group, an improvement of +7.2% in WN group and +14.3% in MMM group and a drop of −21.6% in severe malnourished group suggesting more number of patients gaining nutrition. The present study observed a significant improvement in nutritional status of patients who received counseling by the renal dietician. The reduction in SGA score was independent of reductions in serum creatinine and blood urea levels.

[PMID: 30231860 PMCID: PMC6145210 DOI: 10.1186/s12882-018-1041-z] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Accepted: 09/10/2018] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Metabolic syndrome (MetS) has been established as a risk for cardiovascular diseases and mortality in hemodialysis patients. Energy intake (EI) is an important nutritional therapy for preventing MetS. We examined the association of self-reported dietary EI with metabolic abnormalities and MetS among hemodialysis patients. METHODS A cross-sectional study design was carried out from September 2013 to April 2017 in seven hemodialysis centers. Data were collected from 228 hemodialysis patients with acceptable EI report, 20 years old and above, underwent three hemodialysis sessions a week for at least past 3 months. Dietary EI was evaluated by a three-day dietary record, and confirmed by 24-h dietary recall. Body compositions were measured by bioelectrical impedance analysis. Biochemical data were analyzed using standard laboratory tests. The cut-off values of daily EI were 30 kcal/kg, and 35 kcal/kg for age ≥ 60 years and < 60 years, respectively. MetS was defined by the American Association of Clinical Endocrinologists (AACE-MetS), and Harmonizing Metabolic Syndrome (HMetS). Logistic regression models were utilized for examining the association between EI and MetS. Age, gender, physical activity, hemodialysis vintage, Charlson comorbidity index, high sensitive C-reactive protein, and interdialytic weight gains were adjusted in the multivariate analysis. RESULTS The prevalence of inadequate EI, AACE-MetS, and HMetS were 60.5%, 63.2%, and 53.9%, respectively. Inadequate EI was related to higher proportion of metabolic abnormalities and MetS (p < 0.05). Results of the multivariate analysis shows that inadequate EI was significantly linked with higher prevalence of impaired fasting glucose (OR = 2.42, p < 0.01), overweight/obese (OR = 6.70, p < 0.001), elevated waist circumference (OR = 8.17, p < 0.001), AACE-MetS (OR = 2.26, p < 0.01), and HMetS (OR = 3.52, p < 0.01). In subgroup anslysis, inadequate EI strongly associated with AACE-MetS in groups of non-hypertension (OR = 4.09, p = 0.004), and non-cardiovascular diseases (OR = 2.59, p = 0.012), and with HMetS in all sub-groups of hypertension (OR = 2.59~ 5.33, p < 0.05), diabetic group (OR = 8.33, p = 0.003), and non-cardiovascular diseases (OR = 3.79, p < 0.001). CONCLUSIONS Inadequate EI and MetS prevalence was high. Energy intake strongly determined MetS in different groups of hemodialysis patients.

Protein-energy wasting syndrome in advanced chronic kidney disease: prevalence and specific clinical characteristics. Nefrologia 2017; 38:141-151. [PMID: 28755901 DOI: 10.1016/j.nefro.2017.06.004] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2015] [Revised: 05/19/2017] [Accepted: 06/06/2017] [Indexed: 12/16/2022] Open
Abstract
INTRODUCTION Protein-energy wasting (PEW) is associated with increased mortality and differs depending on the chronic kidney disease (CKD) stage and the dialysis technique. The prevalence in non-dialysis patients is understudied and ranges from 0 to 40.8%. OBJECTIVE To evaluate the nutritional status of a group of Spanish advanced CKD patients by PEW criteria and subjective global assessment (SGA). PATIENTS AND METHODS Cross-sectional study of 186 patients (101 men) with a mean age of 66.1±16 years. The nutritional assessment consisted of: SGA, PEW criteria, 3-day dietary records, anthropometric parameters and bioelectrical impedance vector analysis. RESULTS The prevalence of PEW was 30.1%, with significant differences between men and women (22.8 vs. 33.8%, p < 0.005), while 27.9% of SGA values were within the range of malnutrition. No differences were found between the 2methods. Men had higher proteinuria, percentage of muscle mass and nutrient intake. Women had higher levels of total cholesterol, HDL and a higher body fat percentage. The characteristics of patients with PEW were low albumin levels and a low total lymphocyte count, high proteinuria, low fat and muscle mass and a high Na/K ratio. The multivariate analysis found PEW to be associated with: proteinuria (OR: 1.257; 95% CI: 1.084-1.457, p=0.002), percentage of fat intake (OR: 0.903; 95% CI: 0.893-0.983, p=0.008), total lymphocyte count (OR: 0.999; 95% CI: 0.998-0.999, p=0.001) and cell mass index (OR: 0.995; 95% CI: 0.992-0.998). CONCLUSION Malnutrition was identified in Spanish advanced CKD patients measured by different tools. We consider it appropriate to adapt new diagnostic elements to PEW criteria.

Total kidney and liver volume is a major risk factor for malnutrition in ambulatory patients with autosomal dominant polycystic kidney disease. BMC Nephrol 2017; 18:22. [PMID: 28088190 PMCID: PMC5237538 DOI: 10.1186/s12882-016-0434-0] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2016] [Accepted: 12/28/2016] [Indexed: 01/29/2023] Open
Abstract
Background In patients with autosomal dominant polycystic kidney disease (ADPKD), malnutrition may develop as renal function declines and the abdominal organs become enlarged. We investigated the relationship of intra-abdominal mass with nutritional status. Methods This cross-sectional study was performed at a tertiary hospital outpatient clinic. Anthropometric and laboratory data including serum creatinine, albumin, and cholesterol were collected, and kidney and liver volumes were measured. Total kidney and liver volume was defined as the sum of the kidney and liver volumes and adjusted by height (htTKLV). Nutritional status was evaluated by using modified subjective global assessment (SGA). Results In a total of 288 patients (47.9% female), the mean age was 48.3 ± 12.2 years and the mean estimated glomerular filtration rate (eGFR) was 65.3 ± 25.3 mL/min/1.73 m2. Of these patients, 21 (7.3%) were mildly to moderately malnourished (SGA score of 4 and 5) and 63 (21.7%) were at risk of malnutrition (SGA score of 6). Overall, patients with or at risk of malnutrition were older, had a lower body mass index, lower hemoglobin levels, and poorer renal function compared to the well-nourished group. However, statistically significant differences in these parameters were not observed in female patients, except for eGFR. In contrast, a higher htTKLV correlated with a lower SGA score, even in subjects with an eGFR ≥45 mL/min/1.73 m2. Subjects with an htTKLV ≥2340 mL/m showed an 8.7-fold higher risk of malnutrition, after adjusting for age, hemoglobin, and eGFR. Conclusions Nutritional risk was detected in 30% of ambulatory ADPKD patients with relatively good renal function. Intra-abdominal organomegaly was related to nutritional status independently from renal function deterioration.

Abstract
OBJECTIVE In end-stage renal disease (ESRD) patients, malnutrition is mainly addressed from a pharmacological but not educational point of view. Therefore, the objective of this study was to implement a nutritional education program (NEP) and to evaluate and compare its effectiveness in the treatment and prevention of malnutrition with oral supplementation (OS)-the standard treatment in these patients. DESIGN This study was a longitudinal, 4-month prospective study. SETTINGS The study was conducted from January to May 2012 in the Hemodialysis Fresenius Medical Care Clinic of Murcia. SUBJECTS One hundred twenty patients with ESRD undergoing hemodialysis were randomly assigned to a NEP or to OS. INTERVENTION Patients assigned to the NEP group followed an educational program for 4 months that aimed to improve general nutritional knowledge and included culinary recommendations and an elaboration of balanced menus. The OS group received a nutritional supplement during the hemodialysis procedure. MAIN OUTCOME MEASURE The main outcome measure was certain biochemical markers of nutritional and metabolic status. Nutrition knowledge was also evaluated. RESULTS After 4 months of intervention, nutritional knowledge was increased in all patients (P < .050) after the NEP, which was reflected in a decrease in the prevalence of malnutrition, especially in this group. Creatinine clearance, total protein serum values, and other biochemical parameters improved significantly in both groups (P < .050 in all cases), although other parameters such as C-reactive protein were impaired only in the NEP group. CONCLUSION The NEP was at least as effective as OS for preventing and even treating malnutrition in patients with chronic renal failure on hemodialysis, improving their nutritional status, which may result in a long-term decrease in the mortality and morbidity of these patients.

Abstract
The effect of orally administered sun ginseng (SG), which is a ginseng processed by steaming, was examined in adenine-induced chronic renal failure rat. SG significantly decreased both blood urea nitrogen and serum creatinine levels, indicating an improvement of renal function. Also, SG significantly increased the urinary excretion of both urea and creatinine. Furthermore it lowered the blood pressure, and inhibited adenine-induced kidney hypertrophy and edema. Based on these findings, SG may ameliorate chronic renal failures.

Abstract
INTRODUCTION This study was planned to investigate the relation between dietary macronutrient status and anthropometric measurements in peritoneal dialysis (PD) patients. MATERIALS AND METHODS A total of 28 clinically stable patients were enrolled in this study. All patients were taken a dietary therapy according to the guidelines of the American Journal of Kidney Foundation for 12 weeks. The anthropometric measurements were taken by bioelectrical impedance analyzer. The daily macronutrient intakes of the patients were calculated by the food consumption records. RESULTS The mean age was 48.3 ± 13.10 years [56.3 ± 7.41 years for males (n = 14) and 40.3 ± 12.84 years for females (n = 14)]. There were significant changes in fat percentage (%), total body water (TBW; %, L), extracellular water (ECW; %, L), basal metabolic rate over body weight (BMR/BW), and body fat mass index (BMFI) in males (p < 0.05), but there was no change in females (p > 0.05). The daily dietary energy and protein intakes were under the recommended level in the study period. CONCLUSION Patients undergoing PD frequently have low intakes of protein and energy. It is recommended that individuals undergoing PD periodically maintain 3-day dietary records followed by dietary interviews conducted by a dietitian.

Abstract
Long-term hemodialysis treatment results in chronic monocyte activation with cytokine release. It generates Treg induction with potential immune dysfunction and associated clinical complications. Recent immunological data and preliminary clinical evidence suggest that synthetic polymers and vitamin E coated membranes are associated with a significant improvement in hemodialysis tolerance when compared to cellulose membranes. The aim of this review is to update cytokine release, T-cell polarization, and its clinical impact in patients under extracorporeal hemodialysis comparing traditional cellulose to synthetic/vitamin E coated membranes.

Abstract
Examining the quality and quantity of food intake by appropriate methods is critical in the management of patients with chronic kidney disease (CKD). The four commonly used dietary assessment methods in CKD patients include short-term dietary recalls, several days of food records with or without dietary interviews, urea kinetic based estimates such as protein nitrogen appearance calculation, and food histories including food screeners and food frequency questionnaires (FFQ). There are a number of strengths and limitations of these dietary assessment methods. Accordingly, none of the four methods is suitable in and of itself to give sufficiently accurate dietary information for all purposes. Food frequency questionnaires, which is the preferred method for epidemiological studies, should be used for dietary comparisons of patients within a given population rather than individual assessment. Food histories including FFQ and dietary recalls may underestimate important nutrients, especially in CKD patients. Given the large and increasing number of dialysis patients and work responsibilities of renal dietitians, routine analysis of dietary records and recalls is becoming less feasible. Ongoing and future studies will ascertain additional strengths and limitations of dietary assessment methods in CKD populations including the assessment of food intake during an actual hemodialysis treatment.

Abstract
Gum Arabic (GA [Acacia senegal]) is reputed, in Arabian medicinal practices, to be useful in treating patients with chronic renal failure (CRF), albeit without strong scientific evidence. We have previously shown that GA had no significant effect in rats with CRF induced by surgical nephrectomy. Here, we used another animal model of human CRF (feeding adenine at a concentration of 0.75%(w/w) for four weeks) to test the effect of GA on CRF. Renal morphology and measurements of plasma concentrations of urea and creatinine (Cr), and Cr clearance, in addition to urinary volume, osmolarity and protein concentrations, and N-acetylglucosamine and lactate dehydrogenase activities were performed. Interleukin-6 and the total antioxidant levels in urine, as well as the activity of superoxide dismutase in renal tissues, were estimated. Adenine feeding resulted in marked renal damage. GA (6%(w/v) and 12%(w/v) in drinking water for four consecutive weeks) significantly ameliorated the adverse biochemical alterations indicative of renal failure, abated the decrease in body weight and reduced the glomerular, tubular and interstitial lesions induced by adenine. Our study provides evidence that GA attenuated renal dysfunction in this model of CRF, suggesting a promising potential for it in protecting against renal failure progression. The mechanism(s) of this nephroprotection is uncertain but may involve anti-oxidant and/or anti-inflammatory actions.

Abstract
Introduction To compare outcomes from early post-pyloric to gastric feeding in ventilated, critically ill patients in a medical intensive care unit (ICU). Methods Prospective randomized study. Ventilated patients were randomly assigned to receive enteral feed via a nasogastric or a post-pyloric tube. Post-pyloric tubes were inserted by the bedside nurse and placement was confirmed radiographically. Results A total of 104 patients were enrolled, 54 in the gastric group and 50 in the post-pyloric group. Bedside post-pyloric tube insertion was successful in 80% of patients. Patients who failed post-pyloric insertion were fed via the nasogastric route, but were analysed on an intent-to treat basis. A per protocol analysis was also performed. Baseline characteristics were similar for all except Acute Physiology and Chronic Health Evaluation II (APACHE II) score, which was higher in the post-pyloric group. There was no difference in length of stay or ventilator days. The gastric group was quicker to initiate feed 4.3 hours (2.9 - 6.5 hours) as compared to post-pyloric group 6.6 hours (4.5 - 13.0 hours) (P = 0.0002). The time to reach target feeds from admission was also faster in gastric group: 8.7 hours (7.6 - 13.0 hours) compared to 12.3 hours (8.9 - 17.5 hours). The average daily energy and protein deficit were lower in gastric group 73 Kcal (2 - 288 Kcal) and 3.5 g (0 - 15 g) compared to 167 Kcal (70 - 411 Kcal) and 6.5 g (2.8 - 17.3 g) respectively but was only statistically significant for the average energy deficit (P = 0.035). This difference disappeared in the per protocol analysis. Complication rates were similar. Conclusions Early post-pyloric feeding offers no advantage over early gastric feeding in terms of overall nutrition received and complications Trial Registration Clinical Trial: anzctr.org.au:ACTRN12606000367549

Abstract
BACKGROUND The prevention of malnutrition in patients with progressive chronic kidney disease (CKD) presents a challenge to nephrologists. We evaluated nutritional practice and routines, at a national level, related to the nutritional management of nondialyzed CKD patients. METHODS A questionnaire-based survey (32 open and 9 multiple-choice questions) was used to assess the evaluation of nutritional status in nondialyzed CKD outpatients at baseline and during follow-up. Data were obtained for 230 Italian public nephrology centers (63% of the total number of Italian public nephrology centers). RESULTS There was a dedicated dietitian at only 19% of the centers. At baseline, body weight, body mass index, and serum albumin were determined in almost all centers, nutrient intakes and bioimpedance analysis in half the centers, and subjective global assessment and skinfold thickness in a small proportion of centers. During follow-up, the rate of assessments decreased by 8% for weight, 14% for nutrient intake, and 29% for subjective global assessment and skinfold thickness. Overall, the K/DOQI minimum criteria for nutritional assessment were fulfilled in only two thirds and half of the clinics at baseline and during follow-up, respectively. Multivariate analysis showed that the number of nutritional variables evaluated was significantly related to the size of the CKD clinic and the presence of a dietitian at baseline, but only with the presence of dietitian during follow-up. Daily urinary output was collected at 90% of the centers, but urea and sodium excretions were determined in only 59% and 57% of cases, respectively. The rate of assessment for urinary solutes during follow-up was higher at centers where a very low protein diet was prescribed. CONCLUSIONS The indications about nutritional assessment for CKD patients are poorly translated into practice patterns, especially with respect to the evaluation of nutrient intakes and additional but simple variables such as skinfold-thickness measurement and bioimpedance analysis. The presence of a dedicated dietitian appears to improve the quality of nutritional assessment in CKD.

Abstract
BACKGROUND CKD patients referred to a renal management clinic are looked after by a multidisciplinary team whose care may improve outcome and delay the progression of kidney disease. This paper describes our experience and the results obtained in 940 patients with CKD stage 4 and 5 patients from two renal management clinics (RMC). SUBJECTS AND METHODS We collected and analyzed the data from 940 patients with CKD stage 4 and 5 at the RMCs of the Toronto General Hospital (TGH), University Health Network and The Scarborough General Hospital (TSH) from January 2000 to November 2007. Inclusion criteria for the study required at least three measurements of serum creatinine over a minimum follow-up of 6 months. We calculated the change of slope of the estimated GFR by linear regression analysis. The slopes were further subdivided into five groups: improved eGFR (eGFR slope >or=+5 ml/min/year); mild improvement (slope >+1 to <+5 ml/min/year); stable (slope <+1 to >-1 ml/min/year); slow progression (i.e., deterioration; slope <-1 to >-5 ml/min/year) and rapid progression (slope >-5 ml/min/year). RESULTS During a median follow-up of 1.57 year (range 0.5-8.7 year) of stage 4 patients, eGFR improved in 10.6%, showed mild improvement in 24.2%, was stable in 27.5%, showed slow progression in 28.8% and rapid progression in 8.9% of patients. During a median follow-up of 1.4 year (range 0.5-8 year) of CKD stage 5 patients, eGFR improved in only 1.3%, showed mild improvement in 4.3%, remained stable in 35.6%; showed slow progression in 19.7% and rapid progression in 39.1%. Between the two hospitals (TGH and TSH) there was a statistically significant difference in the number of visits per year for CKD stage 4 patients during the first, second and third year. However, the number of visits per year had no effect on the rate of decline. On univariate analysis, factors predicting non-progression in eGFR slope were eGFR at referral, the use of ACE inhibitors-ARBs and absence of cardiovascular disease. However, in logistic multivariate regression analysis, after adjusting for confounding factors only the eGFR at referral and ACE inhibitors-ARBs were independent factors for non-progression in eGFR. A significant percentage of CKD stage 4 patients attending a renal management clinic (RMC) showed non-progression or improvement in their kidney function. Although only few stage 5 CKD patients had improvement in their eGFR, 32% of them maintained their eGFR on conservative treatment for over 2 years delaying the initiation of dialysis.

Abstract
BACKGROUND The subjective global assessment of nutritional status (SGA) is used to assess the nutritional status of chronic dialysis patients, but longitudinal data in relation to mortality risk are lacking. OBJECTIVE Our objective was to study the long-term and time-dependent associations of the SGA with mortality risk in chronic dialysis patients. DESIGN In a prospective, longitudinal, observational, multicenter study of incident dialysis patients, the 7-point SGA [7 = normal nutritional status; 1 = severe protein-energy wasting (PEW)] was assessed 3 and 6 mo after the start of dialysis and subsequently every 6 mo during 7 y of follow-up. With Cox regression analysis, we calculated hazard ratios (HRs) of the baseline and time-dependent SGA measurements, adjusted for age, sex, treatment modality, primary kidney diseases, and comorbidity. RESULTS In total, 1601 patients were included [mean (+/-SD) age: 59 +/- 15 y; 61% men; 23% with moderate PEW (SGA(4-5)), and 5% with severe PEW (SGA(1-3))]. There was a dose-dependent trend of the 7-point SGA with mortality. Compared with a normal nutritional status at baseline, SGA(4-5) (HR: 1.6; 95% CI: 1.3, 1.9) and SGA(1-3) (HR: 2.1; 95% CI: 1.5, 2.8) were associated with an increase in 7-y mortality. Time-dependently, these associations were stronger: SGA(4-5) (HR: 2.1; 95% CI: 1.7, 2.5) and SGA(1-3) (HR: 5.0; 95% CI: 3.8, 6.5). CONCLUSIONS In dialysis patients, PEW at baseline assessed with SGA was associated with a 2-fold increased mortality risk in 7 y of follow-up. Time-dependently, this association was even stronger, which indicated that PEW was associated with a remarkably high risk of short-term mortality. These data imply that the 7-point SGA may validly distinguish different degrees of PEW associated with increasing risks of mortality.

Abstract
Disorders in calcium, phosphorus, and parathyroid hormone (PTH) are common in chronic kidney disease (CKD) and may be associated with poor outcomes including a higher rate of CKD progression and increased death risk. Although these abnormalities have been examined extensively in patients with CKD stage 5 who are receiving chronic maintenance dialysis, they have not been studied to the same extent at earlier stages of CKD, in spite of the much larger numbers of patients in the early CKD population. We summarize the available literature on outcomes associated with bone and mineral disorders in patients with CKD not yet receiving maintenance dialysis. We have reviewed novel data linking fibroblast growth factor 23 (FGF-23) to phosphorus and vitamin D homeostasis. More rapid CKD progression is linked to hyperphosphatemia and its associated hyperparathyroidism and vitamin D deficiency. Hence, hyperphosphatemia may play a central role in the diverse disorders characterizing CKD. We provide a brief overview of the available treatment recommendations for bone and mineral disorders, with an emphasis on areas needing further research.

Abstract
Aging is associated with many physiological changes in a variety of organ systems. Nevertheless, considerable interest has centred on the possibility that age-related immunological changes may play a key "master" role in regulating many, if not all, subsequent events. A growing body of data, some of it highlighted in this review, supports the notion that host resistance in general is changed in both a qualitative and quantitative manner with age, though the biochemical mechanism(s) underlying such changes are not unique to the immune system per se. Moreover, interventions designed to explore treatments which may reverse some or all of those age-related changes have pointed out a fundamentally important role for nutrition, and the way(s) in which this impacts on host resistance mechanism(s), as having a hitherto unappreciated importance in immunosenescence in general.
