Abstract
Introduction Introduction: Chronic kidney disease (CKD) is characterized by its high prevalence of malnutrition, difficult to detect as it is underestimated by the usual tools. There is no valid or hospital-level nutritional screening tool in Spanish to identify patients with CKD at risk of malnutrition. Objective: to translate and accomplish the transcultural adaptation of Jackson's questionnaire (Renal Inpatient Nutrition Screening Tool [Renal iNUT]) to Spanish, which detects the risk of malnutrition in CKD inpatients and compares it with other nutritional tools. Methods: phase 1: translation, back-translation and transcultural adaptation of the questionnaire from the English to the Spanish version. A pilot test was carried out by nursing staff together with a satisfaction questionnaire. Phase 2: comparison of Renal iNUT with Malnutrition Universal Screening Tool (MUST) and Subjective Global Assessment (SGA). Results: phase 1: the nursing staff's perception was highly favorable. They found it easy or very easy to use and 90 % of them did it in a maximum of ten minutes. Phase 2: from 48 patients included, Renal iNUT detected 44 % at low risk of malnutrition, 28 % at intermediate risk and 28 % at high risk. Increased sensitivity of Renal iNUT (p < 0.007) vs MUST (62.5 vs 33.3 %) and similar specificity (87.1 vs 90.6 %) were found, together with an acceptable correlation compared to SGA (r = 0.75, 95 % CI: 0.67 to 0.83). Conclusions: the Spanish version of Renal iNUT is a useful and easy-to-understand tool for health professionals. We also confirm its good correlation with SGA, with greater sensitivity than MUST for the risk of malnutrition detection in CKD inpatients.

Abstract
PURPOSE To determine predictors of loss of appetite among older adults with chronic kidney disease (CKD). METHODS Demographic and clinical data, and scores of comprehensive geriatric assessment parameters of patients who were ≥ 60 years old and have CKD according to an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73 m2 were reviewed. Loss of appetite was defined as a score of ≤ 28 in The Council on Nutrition Appetite Questionnaire. Logistic regression analysis was performed to determine the predictors of loss of appetite. RESULTS Of the 398 patients included, 288 (72%) were female, and the mean age was 80 ± 7. Loss of appetite was present in 233 (59%) of patients. The frequency appeared to significantly increase with a decline in eGFR to < 45 mL/min/1.73 m2 (p < 0.05). Older age, female sex, the presence of frailty, and higher scores of Insomnia Severity Index and geriatric depression scale-15 were associated with a higher risk of loss of appetite, while longer time on education, higher levels of hemoglobin, eGFR, and serum potassium, and higher scores of handgrip strength, Tinetti gait and balance test, basic and instrumental activities of daily living, and Mini-Nutritional risk Assessment (MNA) were associated with a lower risk (p < 0.05). Associations between insomnia severity and geriatric depression remained significant after adjustment for all parameters including the MNA score. CONCLUSION Loss of appetite is quite common in older adults with CKD and may be a sign of poor health status in older people with CKD. There is a close relationship between loss of appetite and insomnia or depressive mood.

Genetic investigation of the contribution of body composition to anorexia nervosa in an electronic health record setting. Transl Psychiatry 2022; 12:486. [PMID: 36402754 PMCID: PMC9675730 DOI: 10.1038/s41398-022-02251-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 10/31/2022] [Accepted: 11/04/2022] [Indexed: 11/21/2022] Open
Abstract
Anorexia nervosa (AN) is a psychiatric disorder defined by anthropometric symptoms, such as low body weight, and cognitive-behavioral symptoms, such as restricted eating, fear of weight gain, and distorted body image. Recent studies have identified a genetic association between AN and metabolic/anthropometric factors, including body mass index (BMI). Although the reported associations may be under pleiotropic genetic influences, they may represent independent risk factors for AN. Here we examined the independent contributions of genetic predisposition to low body weight and polygenic risk (PRS) for AN in a clinical population (Vanderbilt University Medical Center biobank, BioVU). We fitted logistic and linear regression models in a retrospective case-control design (123 AN patients, 615 age-matched controls). We replicated the genetic correlations between PRSBMI and AN (p = 1.12 × 10-3, OR = 0.96), but this correlation disappeared when controlling for lowest BMI (p = 0.84, OR = 1.00). Additionally, we performed a phenome-wide association analysis of the PRSAN and found that the associations with metabolic phenotypes were attenuated when controlling for PRSBMI. These findings suggest that the genetic association between BMI and AN may be a consequence of the weight-related diagnostic criteria for AN and that genetically regulated anthropometric traits (like BMI) may be independent of AN psychopathology. If so, individuals with cognitive-behavioral symptomatology suggestive of AN, but with a higher PRSBMI, may be under-diagnosed given current diagnostic criteria. Furthermore, PRSBMI may serve as an independent risk factor for weight loss and weight gain during recovery.

Abstract
Purpose The radiolabeled gastrin-releasing peptide receptor (GRPR)-targeting antagonist NeoB is a promising radioligand for imaging and therapy of GRPR-expressing malignancies. In the current study, we aimed to discover the target organs of toxicity and the radiotoxic effects to these organs, when repeated dosages of [177Lu]Lu-NeoB are administered to healthy female and male mice. Methods Animals received either 3 injections, with a 7-day interval, of vehicle (control group 1), 1200 pmol [175Lu]Lu-NeoB (control group 2) or 40 MBq/400 pmol, 80 MBq/800 pmol, and 120 MBq/1200 pmol [177Lu]Lu-NeoB (treatment groups 1, 2, and 3, respectively). At week 5, 19, and 43 after the first injection acute, early, and late organ toxicity, respectively, was determined. For this, histopathological and blood analyses were performed. To correlate the observed toxicity to absorbed dose, we also performed extensive biodistribution and dosimetry studies. Results The biodistribution study showed the highest absorbed doses in GRPR-expressing pancreas, the liver, and the kidneys (the main organs of excretion). Both control groups and almost all animals of treatment group 1 did not show any treatment-related toxicological effects. Despite the high absorbed doses, no clear microscopic signs of toxicity were found in the pancreas and the liver. Histological analysis indicated kidney damage in the form of hydronephrosis and nephropathy in treatment groups 2 and 3 that were sacrificed at the early and late time point. In the same groups, increased blood urea nitrogen levels were found. Conclusion In general, repeated administration of [177Lu]Lu-NeoB was tolerated. The most significant radiotoxic effects were found in the kidneys, similar to other clinically applied radioligands. The results of this study underline the potential of [177Lu]Lu-NeoB as a promising option for clinical therapy.

Abstract
BACKGROUND As kidney disease progresses, patients often experience a variety of symptoms. There are very few studies reporting spectrum of predialysis patients' symptoms in peritoneal dialysis (PD) patients. Furthermore, the clinical significance of predialysis patients' symptoms for PD patients' prognosis remains unknown. METHODS In this retrospective cohort study, patients who started PD during 1 January 2006 to 31 January 2018 were included. Patients' predialysis symptoms and clinical parameters were obtained. Both the short- and long-term patients' outcome were investigated by Cox regression and Kaplan-Meier's survival analysis to identify the relationship between clinical symptoms and patients' mortality on PD. RESULTS A total of 898 incident PD patients were included. The anorexia (58%) was the most common predialysis symptom in the present cohort, followed by insomnia (32.7%), fatigue (27.6%), syndromes of heart failure (27.6%), and nausea (20.5%). The only symptom significantly associated with both six-months and 12-months mortality on PD was nausea (HR 2.359, 95% CI 1.377-4.040, p=.002 and HR 1.791, 95% CI 1.176-2.729, p=.007, respectively). But in the long-term, anorexia (HR 1.392, 95% CI 1.070-1.811, p=.014) was the only symptom significantly associated with patient's all-cause mortality after adjusting for other confounding factors. CONCLUSIONS Our study demonstrated that nausea and anorexia were the most important predialysis symptoms, which was associated with patients' short- and long-term mortality on PD treatment, respectively. The results indicated that predialysis evaluation and management of symptoms of nausea and anorexia may be a possible way to improve patients' outcome on PD.

Abstract
Although research has shown that loneliness can contribute to anorexia in older non-ESRD (end-stage renal disease) populations, and the benefits of its mitigation with improving appetite, nutrient, and caloric intake, its implications for older patients with ESRD have been overlooked. This article provides an overview of evidence on the potential contributing role of loneliness in anorexia of older patients with ESRD, and loneliness as a focal point for interventions to help improve nutritional status. Areas of needed research are suggested in the course of the analysis. With a 41%-83% projected rise in the prevalence of patients in the United States with ESRD by 2030, and demographic population trends showing that an ever-increasing number will be living alone, there is a long overdue need to better understand the implications of loneliness for this nutritionally vulnerable population. KEYWORDS: Chronic kidney disease; loneliness; anorexia; malnutrition; protein energy wasting.

Urinary magnesium predicts risk of cardiovascular disease in Chronic Kidney Disease stage 1-4 patients. Clin Nutr 2020; 40:2394-2400. [PMID: 33160701 DOI: 10.1016/j.clnu.2020.10.036] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 10/16/2020] [Accepted: 10/19/2020] [Indexed: 12/23/2022]
Abstract
Observational studies on dietary or circulating magnesium and risk of cardiovascular disease (CVD) in Chronic Kidney Disease (CKD) stage 1-4 have reported no-to-modest inverse associations. 24 h Urinary magnesium concentration (24 h UMg), an indicator of intestinal magnesium absorption, may provide better insight into the connection of CKD progression. We examined 3179 participants aged 18-74 years with CKD stage 1-4 in the Chinese Cohort Study of Chronic Kidney Disease (C-STRIDE) study, a prospective population-based cohort study. Data were analysed using Spearman rank-order correlation coefficients for all comparisons. We also performed a time-to-event analysis of the data using the Kaplan-Meier survival model, Cox proportional hazard model and competing risk Fine and Gray subdistribution hazard model. During a median follow-up of 4.19 years (interquartile range, 3.43-5.09 years), when modelling end-stage renal disease (ESRD), CVD and death, 24 h UMg was associated with risk of CVD (HR, 1.612 (95% CI, 1.056-2.460)), while no significant association with ESRD and death endpoints could be detected. 24 h UMg risk variants display a modest association with CVD in CKD stage 1-4 patients.

Abstract
This study aimed to analyze the association between serum zinc levels and major subjective symptoms in zinc deficiency patients with chronic liver disease. 578 patients with chronic liver disease were enrolled. The patients, whose serum zinc level of <80 µg/dl, completed a questionnaire to determine whether they had subjective symptoms of the five conditions (taste disorder, aphthous stomatitis, dermatitis, alopecia, and anorexia). Then, the association between these subjective symptoms and serum zinc levels was analyzed. In total, 193 patients (33.4%) experienced any subjective symptoms. The prevalence of each symptom was as follows: 36 patients with taste disorder (6.2%), 46 with aphthous stomatitis (8.0%), 77 with dermatitis (13.3%), 46 with alopecia (8.0%), and 53 with anorexia (9.2%). In total, 70.8%, 34.1%, and 26.1% patients with serum zinc levels of <40, ≥40 to <60, and ≥60 to <80 µg/dl, respectively, had these symptoms. When zinc deficiency was defined as a serum zinc level of <80 µg/dl, approximately one-third of patients displayed symptoms presumably originating from zinc deficiency. As serum zinc levels decreased, the prevalence of these symptoms increased. Dermatitis, especially, was relevant to zinc.

Association between BMI changes and mortality risk in children with end-stage renal disease. Pediatr Nephrol 2019; 34:1557-1563. [PMID: 30963283 DOI: 10.1007/s00467-019-04249-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2018] [Revised: 01/28/2019] [Accepted: 03/26/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND Few studies have examined how changes in BMI [body mass index] over time associate with risk of adverse outcomes in children receiving renal replacement therapy [RRT]. The objective of this study was to examine the association between annualized changes in BMI and the risk of death in children treated with RRT. METHODS We performed a retrospective cohort study of 1182 pediatric dialysis and transplant patients in the Pediatric Growth and Development Special Study of the United States Renal Data System. Quintiles of annualized change in BMI z-score (with cutoffs of - 0.50, - 0.13, 0.09, 0.57) were used as the primary predictor, with the middle quintile (- 0.13 to 0.09) serving as the reference category. Cox models were used to examine the association between exposure and death, with time of analysis starting from the second BMI measurement. RESULTS Median follow-up time to death or censoring was 6 years. Median age was 14.6 years, and 61% of children had a functional graft at cohort entry. There was a U-shaped association between BMI change and mortality risk: a large decline in annualized BMI z-score change (> - 0.50) was associated with an increased risk of death (adjusted hazard ratio [aHR] 1.54 (95% CI 1.17-2.03), p = 0.002). A large increase in annualized BMI z-score change (> 0.57) was also associated with an increased risk of death (aHR 1.44 (95% CI 1.07-1.92), p = 0.02). No interaction was noted between annualized BMI change and initial treatment modality (dialysis or transplant, p = 0.15). CONCLUSIONS Maintenance of a stable BMI in pediatric patients receiving RRT may be associated with improved survival.

Abstract
Background: Appetite disorders are frequent and scantly studied in peritoneal dialysis (PD) patients and are associated with malnutrition and cardiovascular complications. Objective: We investigated the relationship between uremic insulin resistance, pro-inflammatory cytokines, and appetite-related peptides release (ARPr) with eating-behavior disorders in PD patients. Methods: We included 42 PD patients (12 suffering anorexia, 12 obese with high food-intake, and 18 asymptomatic) and 10 controls. We measured blood levels of ARPr including orexigens [neuropeptide-Y (NPY), ghrelin, and nitric-oxide], anorexigens [cholecystokinin, insulin, corticotropin-releasing factor, leptin, and adiponectin (Ad)], and cytokines (TNF-α, sTNFα-R2, and IL-6) both at baseline and after administering a standard-food stimulus (SFS). We also measured the expression of TNF-α, leptin and Ad-encoding mRNAs in abdominal adipose tissue. We compared these markers with eating motivation measured by a Visual Analog Scale (VAS). Results: Anorexics showed both little appetite, measured by a VAS, and low levels of orexigens that remained constant after SFS, coupled with high levels of anorexigens at baseline and after SFS. Obeses showed higher appetite, increased baseline levels of orexigens, lower baseline levels of anorexigens and cytokines and two peaks of NPY after SFS. The different patterns of ARPr and cytokines pointed to a close relationship with uremic insulin resistance. In fact, the euglycemic-hyperglycemic clamp reproduced these disorders. In anorexics, TNF-α fat expression was increased. In obese patients, leptin expression in fat tissue was down-regulated and showed correlation with the appetite. Conclusion: In PD, appetite is governed by substances that are altered at baseline and abnormally released. Such modulators are controlled by insulin metabolism and cytokines and, while anorexics display inflammatory predominance, obese patients predominantly display insulin resistance.

Murray DP, Young L, Waller J, Wright S, Colombo R, Baer S, Spearman V, Garcia-Torres R, Williams K, Kheda M, Nahman NS. Is Dietary Protein Intake Predictive of 1-Year Mortality in Dialysis Patients? Am J Med Sci 2018; 356:234-243. [PMID: 30286818 DOI: 10.1016/j.amjms.2018.06.010] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2018] [Revised: 05/26/2018] [Accepted: 06/08/2018] [Indexed: 01/16/2023]
Abstract
BACKGROUND High mortality in dialysis patients may be associated with protein-energy wasting (PEW) syndrome characterized by progressively depleted protein and energy stores. While early diagnosis and treatment of PEW can reduce mortality, clinically practical measures for its detection are lacking. Poor dietary protein intake (DPI) is associated with risk of malnutrition and PEW. However, the impact of DPI on mortality is unclear. The purpose of this study is to examine the ability of DPI to predict 1-year mortality in dialysis patients. METHODS This prospective, secondary study using data from the Comprehensive Dialysis Study and United States Renal Data System examined risk factors associated with 1-year mortality in dialysis patients. RESULTS Seventeen (7.5%) of the 227 subjects died within 1 year following baseline data collection. One year survivors were significantly younger (60 ± 13.6 versus 71 ± 12.8; P = 0.0043), had a lower Charlson Comorbidity Index score (1.6 ± 2.3 versus 4.0 ± 3.6; P = 0.0157), higher serum albumin level (3.5 ± 0.5 versus 3.3 ± 0.4; P = 0.0173) and had higher DPI (63 ± 33.7 versus 49.5 ± 21.5 g/day; P = 0.0386) than those who died. In multivariable Cox proportional hazards model analyses, only the Charlson Comorbidity Index adjusted hazard ratio for death (1.24) was significantly associated with increased mortality. The Comprehensive Dialysis Study data showed no association between DPI and 1-year mortality in dialysis patients. CONCLUSIONS Future studies using more precise measures should further examine the impact of DPI on mortality given the known association of DPI with PEW syndrome and the definitive link between PEW syndrome and survival in dialysis patients.

Abstract
BACKGROUND Few studies have investigated the changes in weight that may occur over time among adults with the progression of chronic kidney disease (CKD). Whether such weight changes are independently associated with death after the onset of end-stage renal disease has also not been rigorously examined. STUDY DESIGN Prospective cohort study. SETTING & PARTICIPANTS We studied 3,933 participants of the Chronic Renal Insufficiency Cohort (CRIC) Study, a longitudinal cohort of patients with CKD. We also performed similar analyses among 1,067 participants of the African American Study of Kidney Disease and Hypertension (AASK). PREDICTORS Estimated glomerular filtration rate (eGFR) and weight change during CKD. OUTCOME Weight and all-cause mortality after dialysis therapy initiation. RESULTS During a median follow-up of 5.7 years in CRIC, weight change was not linear. Weight was stable until cystatin C-based eGFR (eGFRcys) decreased to <35mL/min/1.73m2; thereafter, weight declined at a mean rate of 1.45 kg (95% CI, 1.19-1.70) for every 10 mL/min/1.73m2 decline in eGFRcys. Among the 770 CRIC participants who began hemodialysis or peritoneal dialysis therapy during follow-up, a >5% annualized weight loss after eGFR decreased to <35mL/min/1.73m2 was associated with a 54% higher risk for death after dialysis therapy initiation (95% CI, 1.17-2.03) compared with those with more stable weight (annualized weight changes within 5% of baseline) in adjusted analysis. Similar findings were observed in the AASK. LIMITATIONS Inclusion of research participants only; inability to distinguish intentional versus unintentional weight loss. CONCLUSIONS Significant weight loss began relatively early during the course of CKD and was associated with a substantially higher risk for death after dialysis therapy initiation. Further studies are needed to determine whether interventions to optimize weight and nutritional status before the initiation of dialysis therapy will improve outcomes after end-stage renal disease.

Muscle wasting in chronic kidney disease. Pediatr Nephrol 2018; 33:789-798.

Abstract
Loss of lean body mass is a relevant component of the cachexia, or protein energy wasting (PEW), syndrome. Reduced muscle mass seems to be the most solid criterion for the presence of cachexia/PEW in patients with chronic kidney disease (CKD), and those with greater muscle mass loss have a higher risk of death. Children with CKD have many risk factors for lean mass and muscle wasting, including poor appetite, inflammation, growth hormone resistance, and metabolic acidosis. Mortality risks in patients with CKD increases as body mass index (BMI) and weight decreases. However, data regarding cachexia/PEW and muscle wasting in children with CKD is scarce due to lack of consensus in diagnostic criteria and an appropriate investigative methodology. Further research is urgently needed to address this important complication in the pediatric CKD setting, which may have fundamental impact on clinical outcomes.

Abstract
BACKGROUND Anorexia and malnutrition are associated with poor outcomes in children with chronic kidney disease (CKD). STUDY DESIGN Observational cohort study. SETTING & PARTICIPANTS We assessed changes in body mass index (BMI) as kidney function declines and its association with risk for end-stage renal disease (ESRD) among 854 participants followed between 2005 to 2013 in the CKD in Children (CKiD) Study. PREDICTORS Repeated measurements of estimated glomerular filtration rate (eGFR) by serum creatinine concentration in our trajectory analysis using mixed models; change in BMI z score (per year) after eGFR decreased to <35mL/min/1.73m2 in logistic regression models. OUTCOMES Repeated measurements of BMI z score (as a reflection of weight status) in our trajectory analysis; ESRD in logistic regression models. RESULTS During a mean longitudinal follow-up of 3.4 years, BMI z scores remained stable until eGFR decreased to <35mL/min/1.73m2. When eGFR decreased to <35mL/min/1.73m2, a mean decline in BMI z score of 0.13 (95% CI, 0.09-0.17) was noted with each 10-mL/min/1.73m2 further decline in eGFR. This was statistically significantly different from the weight trajectory when eGFR was ≥35mL/min/1.73 m2 (P<0.001). Among children and adolescents with significant weight loss (defined as decline in BMI z score > 0.2 per year) after eGFR decreased to <35mL/min/1.73m2, the odds of ESRD was 3.28 (95% CI, 1.53-7.05) times greater compared with participants with stable BMI z scores (BMI z score change per year of 0-0.1). LIMITATIONS Observational nature of our study, lack of longitudinal assessments of inflammatory markers. CONCLUSIONS In children and adolescents with CKD, weight loss mostly occurs when eGFR decreases to <35mL/min/1.73m2, and this weight loss was associated with higher risk for ESRD. Further studies are needed to define the reasons for the association between weight loss and more rapid progression to ESRD in children and adolescents.

Abstract
Patients with chronic kidney disease (CKD) commonly complain upper gastrointestinal (GI) symptoms, especially anorexia. Hemodialysis (HD) has been noted to improve GI symptoms; however, the underlying mechanisms are unclear. This study was designed 1) to study effects of HD on GI symptoms and gastric slow waves; and 2) to investigate possible roles of ghrelin and glucagon-like peptide-1 (GLP-1): the study recruited 13 healthy controls, 20 CKD patients without HD (CKD group), and 18 CKD patients with HD (HD group). Dyspeptic symptoms, autonomic functions, gastric slow waves, and plasma level of ghrelin and GLP-1 were analyzed. First, the CKD patients with HD showed markedly lower scores of anorexia (0.6 ± 0.2 vs. 3.2 ± 0.4, P < 0.001) compared with patients without HD. Second, the CKD group but not HD group showed a significant reduction (25.6%) in the percentage of normal gastric slow waves, compared with controls. Third, the CKD group exhibited a significantly lower ghrelin level compared with the HD group (26.8 ± 0.9 vs. 34.1 ± 2.3 ng/l, P < 0.02) and a higher GLP-1 level (29.4 ± 2.8 vs. 20.0 ± 2.1 pmol/l, P < 0.05) compared with controls. Moreover, the percentage of normal slow waves was positively correlated with ghrelin (r = 0.385, P = 0.019) but negatively correlated with GLP-1 (r = -0.558, P < 0.001) in all CKD patients. Hemodialysis improves upper GI symptoms and gastric slow waves in CKD patients. An increase in ghrelin and a decrease in GLP-1 might be involved in the HD-induced improvement in gastric slow waves.

Abstract
Neonatal chronic kidney disease (CKD) occurs with an estimated incidence of 1 in 10,000 live births, whereas the incidence of neonatal end-stage renal disease (ESRD) is about 7.1 per million age-related population. The most frequent etiologies are renal hypoplasia/dysplasia, posterior urethral valves, and other congenital anomalies of the kidney and urinary tract. Other etiologies include polycystic kidney disease, cortical necrosis, and renal vascular thrombosis. Management of CKD focuses primarily on replacing renal functions such as erythropoietin, 1,25-hydroxylation of vitamin D, electrolyte homeostasis/excretion, and, in ESRD, waste product removal. Nutrition and growth monitoring are of utmost importance, with the majority of ESRD infants requiring gastrostomy tube for nutrition. Outcomes of neonates (<31 days) started on dialysis continue to improve, with large cohort studies showing 2-3-year survival rates of 79-81%. As in other neonatal disciplines, the gestational age and size limits for safe provision of dialysis continue to decrease.

Abstract
Patients with chronic kidney disease (CKD) often require regular hemodialysis (HD) to prolong life. However, between HD sessions, patients have to restrict their diets carefully to avoid excess accumulation of potassium, phosphate, sodium, and fluid, which their diseased kidneys can no longer regulate. Failure to adhere to their renal dietary regimes can be fatal; nevertheless, non-adherence is common, and yet little is known about the psychological variables that might predict this dietary behavior. Thus, this study aimed to assess whether dietary adherence might be affected by a variety of psychological factors including stress, personality, and health locus of control, as well as dietary knowledge, in chronic HD patients. Fifty-one patients (30 men; age range 25-85) who had undergone HD for at least 3 months and had been asked to restrict at least one of potassium, phosphate or fluid, were recruited from a hospital renal unit. Measures of adherence to each of potassium, phosphate, and fluid were derived from standard criteria for these physiological indices in renal patients. Knowledge of food/drink sources of these dietary factors, and their medical implications in relation to HD and CKD were assessed by a bespoke questionnaire. Psychological factors including stress, personality and health locus of control beliefs were measured by standardized questionnaires. Having to restrict a particular nutrient was associated with better knowledge of both food sources and medical complications for that nutrient; however, greater dietary knowledge was not linked to adherence, and knowledge of medical complications tended to be associated with poorer adherence to potassium and phosphate levels. Adherence to these two nutrient requirements was also associated with lower reported stress in the past week. Adherence was associated with differences in locus of control: these differences varied across indices although there was a tendency to believe in external loci. For potassium, phosphate, and fluid restriction, adherers were less likely to be sensation seekers but did not differ from non-adherers on impulsivity, anxiety sensitivity, or hopelessness. In conclusion, the links between dietary adherence and stress, locus of control and personality suggests that screening for such psychological factors may assist in managing adherence in HD patients.

Possible prevention of uremic nausea by vitamin D receptor activators in non-dialysis patients with stage 5 chronic kidney disease. Clin Exp Nephrol 2016; 21:825-834.

Abstract
Background Nausea is a major uremic symptom and a frequent indication for starting dialysis. However, preventive medication for uremic nausea has not yet been identified. Vitamin D receptor activators (VDRAs) may prevent uremic nausea via their pleiotropic actions. The objective of this study was to explore whether VDRA administration during the predialysis period is associated with a reduced prevalence of uremic nausea just prior to beginning dialysis. Methods A multicenter, retrospective, cross-sectional study was performed to identify a medication to prevent uremic nausea. Patients with stage 5 CKD who were followed-up over 3 months were included. The primary outcomes examined were the prevalence of uremic nausea, congestive heart failure (CHF), and intractable edema at dialysis commencement. The predictor variable was VDRA use during the predialysis period. Results One thousand five hundred and thirty six patients who had just begun dialysis in nine Japanese facilities between January 2006 and October 2013 were included. Two hundred and thirty (15.0%) patients had commenced dialysis because of uremic nausea, and three hundred and ninety two (25.5%) patients had been using VDRAs before initiating dialysis. Logistic regression analysis showed that, among the medications examined in this study, only VDRA use was independently associated with a lower frequency of uremic nausea (OR 0.512, 95% CI 0.347–0.738, P = 0.0003). On the other hand, CHF and intractable edema were not associated with VDRA administration. Conclusion Use of VDRAs during the predialysis period was the only factor associated with a lower prevalence of uremic nausea, suggesting that VDRAs may prevent uremic nausea in patients with advanced CKD.

Abstract
Chronic pancreatitis (CP) and pancreatic adenocarcinoma (PDAC) are the most common diseases of the pancreas. Cachexia-weight loss exceeding 10% of stable body weight-is present in up to 80% of patients with PDAC. Because the mechanisms of cachexia are not well known, this provides a possibility to compare clinical courses of benign and malignant cachexia. In this study, 382 patients-242 with a PDAC stage UICC II/ 140 with CP-were documented regarding the prevalence of cachexia and its influence on perioperative morbidity and mortality with a special interest to postoperative weight gain and survival. Cachexia was present in 41.4% of CP and 31% of cancer patients. We could demonstrate more pronounced systemic effects of cachexia in patients with PDAC. Weight loss was faster in PDAC patients, the amount of weight loss did not differ significantly between the groups. Cachexia had a significant impact on survival and the postoperative course in patients with PDAC and tumor resection. The development of cachexia is faster in patients with a malignant disease and the systemic effects are more pronounced. Therefore, tumor cachexia should be considered as a different entity than cachexia in benign diseases.

Abstract
BACKGROUND Many maintenance dialysis patients experience a common cluster of symptoms, including diminished appetite (anorexia). This symptom has been associated with reduced quality of life and increased mortality in this population. AIM The aim of this study was to determine whether diminished appetite is a significant predictor of negative clinical outcomes in patients on peritoneal dialysis (PD). METHOD A longitudinal prospective study was conducted in 98 patients receiving PD in Beijing, China. Clinical characteristics, nutritional and inflammatory marker levels, and related peritoneal treatment information were collected. The appetite status and serum albumin levels were assessed initially and reevaluated monthly during the first year of follow-up. All patients were followed for nearly 5 years or until death. Data were collected about mortality, hospitalization, and peritonitis. RESULTS The mean age of participants was 60.3 ± 14.4, and 22.8% reported diminished appetite. At baseline, female sex, cardiovascular disease, and prealbumin level were the significant predictors of appetite. The average length of follow-up was 39 (range: 2-57) months. The Kaplan-Meier survival curve showed the survival rate was lower in patients reporting diminished appetite than for patients reporting normal appetite. Multivariate analysis indicated that diminished appetite, diabetes, ferritin, and serum albumin levels were independent predictors of mortality. CONCLUSION Self-reported appetite was a predictor of clinical characteristics and outcome for patients receiving PD. Conducting appetite evaluation periodically is recommended as a nursing strategy to improve care for these patients.

Abstract
To assess whether endocrine dysfunction may cause derangement in energy homeostasis in patients undergoing hemodialysis (HD), we profiled hormones, during a 3-day period, from the adipose tissue and the gut and the nervous system around the circadian clock in 10 otherwise healthy HD patients and 8 normal controls. The protocol included a 40-h fast. We also measured energy-protein intake and output and assessed appetite and body composition. We found many hormonal abnormalities in HD patients: 1) leptin levels were elevated, due, in part, to increased production, and nocturnal surge in response to daytime feeding, exaggerated. 2) Peptide YY (PYY), an anorexigenic gut hormone, was markedly elevated and displayed an augmented response to feeding. 3) Acylated ghrelin, an orexigenic gut hormone, was lower and did not exhibit the premeal spike as observed in the controls. 4) neuropeptide Y (NPY), a potent orexigenic peptide, was markedly elevated and did not display any circadian variation. 5) Norepinephrine, marginally elevated, did not exhibit the normal nocturnal dip. By contrast, α-melanocyte-stimulating hormone and glucagon-like peptide-1 were not different between the two groups. Despite these hormonal abnormalities, HD patients maintained a good appetite and had normal body lean and fat mass, and there was no evidence of increased energy expenditure or protein catabolism. We explain the hormonal abnormalities as well as the absence of anorexia on suppression of parasympathetic activity (vagus nerve dysfunction), a phenomenon well documented in dialysis patients. Unexpectedly, we noted that the combination of high leptin, PYY, and NPY with suppressed ghrelin may increase arterial blood pressure, impair vasodilatation, and induce cardiac hypertrophy, and thus could predispose to adverse cardiovascular events that are the major causes of morbidity and mortality in the HD population. This is the first report attempting to link hormonal abnormalities associated with energy homeostasis to adverse cardiovascular outcome in the HD patients.

Abstract
Depression is a common co-morbid condition in patients suffering from a variety of chronic medical conditions. In spite of this, mental health of patients with chronic kidney disease is understudied. Accurate estimation of the prevalence of depressive disorders in this population is difficult due to the different definitions and assessment techniques and the overlap of depressive symptomatology with symptoms of uremia. Several potential pathways link depression and chronic kidney disease. The association between the two conditions is probably bidirectional. Consequently, treatment of mood disorders could impact medical outcome. Very little has been published about the therapeutic options for depression in patients with chronic kidney disease. Available data, however, suggest that several antidepressant medications and psychotherapeutic methods are likely to be safe and effective also in this population. In this review, which is the second of a series of reviews on this topic, we provide an overview of the literature concerning the diagnosis, screening and therapy of depressive disorders in patients with chronic kidney disease.
