The present systematic review and meta-analysis aims to compare the effect of bicarbonate hemodialysis and HDF on quality of life (QoL), fatigue, and time to recovery in end-stage renal disease (ESRD) patients. Searches were run on January 2024 and updated on 3 March 2024 in the following databases: Ovid MEDLINE (1985 to present); Ovid EMBASE (1985 to present); Cochrane Library (Wiley); PubMed (1985 to present). Ten articles were fully assessed for eligibility and included in the investigation. Compared to HD, online HDF had a pooled MD of the mental component score (MCS) of the SF-36 of 0.98 (95% CI - 0.92, 2.87; P = 0.31). and of the physical component score (PCS) of 0.08 (95% CI - 1.32, 1.48; P = 0.91). No significant heterogeneity was observed (Chi 2  = 4.85; I 2  = 38%; P = 0.18 and Chi 2  = 3.85; I 2  = 22%; P = 0.28, respectively). Studies that compared the QoL assessed through the Kidney Disease Questionnaire or KDQOL-SF and show that HDF does not improve QoL when compared with HD, in most studies. In five out of seven studies, HDF was not significantly more effective than HD in improving fatigue. The length of the recovery time resulted in similar in patients receiving HDF and HD in all studies included in the present review. HDF is not more effective than HD in improving QoL and fatigue and in reducing the length of time of recovery after dialysis., (© 2024. The Author(s).)

Purpose: The present systematic review and meta-analysis aimed at evaluating the effect of low dialysate sodium concentration on interdialytic weight gain (IDWG) in chronic hemodialysis patients., Methods: Studies were eligible for inclusion if they were English language papers published in a peer-reviewed journal and met the following inclusion criteria: (1) studies in adult patients (over 18 years of age), (2) included patients on chronic hemodialysis since at least 6 months; (3) compared standard (138-140 mmol/l) or high (> 140 mmol/l) dialysate sodium concentration with low (< 138 mmol/l) dialysate sodium concentration; (4) Included one outcome of interest: interdialytic weight gain. Medline, PubMed, Web of Science, and the Cochrane Library were searched for the quality of reporting for each study was performed using the Quality Assessment Tool of Controlled Intervention Studies of the National Institutes of Health. The quality of reporting of each cross-over study was performed using the Revised Cochrane Risk of Bias (RoB) tool for cross-over trials as proposed by Ding et al. RESULTS: Nineteen studies (710 patients) were included in the analysis: 15 were cross-over and 4 parallel randomized controlled studies. In cross-over studies, pooled analysis revealed that dialysate sodium concentration reduced IDWG with a pooled MD of - 0.40 kg (95% CI - 0.50 to - 0.30; p < 0.001). The systematic review of four parallel, randomized, studies revealed that the use of a low dialysate sodium concentration was associated with a significant reduction of the IDWG in two studies, sustained and almost significant (p = 0.05) reduction in one study, and not significant reduction in one study., Conclusion: Low dialysate sodium concentration reduces the IDWG in prevalent patients on chronic hemodialysis., (© 2024.

Objective: The present systematic review and meta-analysis aims to determine the difference in the interdialytic weight gain (IDWG) between low salt intake diet and normal/high salt intake diet or between nutritional counseling aimed at reducing diet salt intake and no nutritional counseling in patients on chronic hemodialysis., Methods: Medline, PubMed, Web of Science, and the Cochrane Library were searched. Randomized, crossover or parallel studies and observational studies were considered for inclusion and: 1) included adult patients on chronic hemodialysis since at least 6 months; 2) compared normal salt intake diet with low salt intake diet on IDWG; 3) compared nutritional counseling aimed at reducing diet salt intake with no intervention on IDWG; 4) reported on IDWG., Results: Eight articles (783 patients) were fully assessed for eligibility and included in the investigation. Meta-analysis showed frequencies of patients that increased their weight after dialysis more than 2.5 Kg (events) over total enrolled subjects for each group (control and experimental). As no significant heterogeneity was observed (I 2  = 8%; p = 0.36), the pooled analysis was performed using a fixed-effect model. Funnel plot was generated and no obvious asymmetry was observed. The Overall Odds Ratio to get an event in the experimental group, in respect to controls, is 0.57 (0.33-0.97) (p = 0.04] with single studies OR ranging between 0.11 and 1.08., Conclusion: The present systematic review and meta-analysis suggest that the use of a low salt diet sodium or a nutritional counseling aimed at reducing diet salt intake is associated with a statistically significant reduction of the IDWG in patients on chronic hemodialysis., Competing Interests: Declaration of competing interest None., (Copyright © 2024 European Society for Clinical Nutrition and Metabolism.

Objective: The use of selective serotonin reuptake inhibitors (SSRIs) is common among hemodialysis patients who receive treatment for depression. However, studies on the efficacy of SSRIs in patients on chronic hemodialysis are few and have led to conflicting results. The present systematic review aims to evaluate, in randomized, controlled studies (RCSs), the efficacy of SSRI administration in reducing symptoms of depression in patients on chronic hemodialysis when compared with placebo or psychological interventions. Method : Research was run on December 2023 in the following databases: Ovid MEDLINE (1985 to present); Ovid EMBASE (1985 to present); Cochrane Library (Wiley); and PubMed (1985 to present). The primary outcome was the frequency and severity of the symptoms of depression assessed through the Beck Depression Inventory (BDI) or the Hamilton Depression Rating Scale (HAMD). The secondary outcome was the prevalence of adverse events. Results : Seven studies totaling 433 patients were included. The number of patients in each individual study ranged from 13 to 120. The length of studies ranged from 8 weeks to 6 months. Heterogeneous data precluded informative meta-analysis. Three studies compared sertraline with a placebo. Of these, two demonstrated that sertraline was better than the placebo in reducing the symptoms of depression while one showed no statistically significant differences between sertraline and the placebo. One study, comparing fluoxetine with a placebo showed that the symptoms of depression did not differ significantly at 8 weeks. In another study, escitalopram administration led to a significantly greater reduction in the Hamilton Depression Rating Scale score compared to a placebo, as well as in the Hamilton Anxiety Rating Scale score. In one study, citalopram and psychological interventions were both effective in reducing the symptoms of depression and anxiety and, in another study, sertraline was modestly more effective than CBT at 12 weeks in reducing the symptoms of depression. Conclusions : SSRIs may be effective in reducing the symptoms of depression in patients on chronic hemodialysis. SSRI administration, at the dosage used in the studies included in the present systematic review, seems safe in most hemodialysis patients. However, the paucity of studies and the limited number of patients included in the trials may suggest that further randomized, controlled studies are needed to determine if SSRIs may be used routinely in daily clinical practice in such a population.

Background: Aim of the present study was to assess whether post-dialysis fatigue (PDF) may be related to pre- or post-dialysis levels of serum S100B protein. Hemodialysis patients (HD) who answered to be fatigued after their hemodialysis sessions when asked: "Do you feel worse after dialysis? if they answered yes" were considered to suffer from PDF. Serum Interleukins (IL-1β, IL-6, IL-10), TNF-α and S100B were assessed by ELISA kit., Results: Thirty HD patients were studied: 22 (73.4%) reported to suffer from PDF. Serum S100B post-dialysis levels (median [IQR] = 17.4 μg [7.1 to 30.9]) were significantly higher than serum S100B pre-dialysis levels (median [IQR] = 5 μg [1.4 to 22.1]; p = 0.0001). S100B post-dialysis was significantly higher than S100B pre-dialysis either in patients with PDF or without PDF., Conclusions: Pre- and post-dialysis values of serum S100B and its delta did not differ significantly between patients with and without PDF and were not associated with the length of the TIRD in patients on chronic hemodialysis., (© 2022 International Society for Apheresis and Japanese Society for Apheresis.)

Background: No available and easy to administer cognitive test has been evaluated for the prediction of mortality in prevalent patients on chronic hemodialysis. The aim of the present study was to determine if the Mini-Mental State Examination (MMSE) was predictor of mortality in patients on chronic hemodialysis., Methods: One hundred twenty-seven prevalent patients on chronic hemodialysis were studied. All patients underwent assessment of cognitive function through the MMSE. The MMSE was administered during a midweek hemodialysis session, avoiding the beginning and the end of each treatment to minimize the effects of fluctuations in uremic syndrome or blood pressure in accordance with a previous study. An MMSE score ≤23 was used as indicative of cognitive impairment. Demographic, clinical, and laboratory parameters were recorded for each patient., Results: Mean (SD) MMSE was 23.2 ± 4.1. Median MMSE was 24 (min-max: 2-30). MMSE was ≤23 in 72 patients and >23 in 55. With data updated in March 2021, after a mean follow-up of 58.8 ± 41 months (range: 2-156 months), 75 patients died, and 17 were transplanted. None was lost to follow-up or was transferred to another unit. Dead participants, as compared with alive ones, were significantly older, had a higher Charlson Index score, had lower Activities daily living and Instrumental activities daily living, and had a lower MMSE score and lower serum albumin levels. Kaplan-Meier analysis showed that survival was significantly lower in patients with MMSE ≤23 than in those with MMSE >23 (log-rank χ 2 : 8.825, p = 0.003). According to Cox regression analysis, mortality was associated with age and inversely associated with MMSE., Conclusion: We show that the MMSE predicts mortality in prevalent patients on chronic hemodialysis., (© 2022 Wiley Periodicals LLC.)

Background: This work aimed to shed light on the notorious debate over the role of an educational/cognitive/behavioral or psychological approach in the reduction of interdialytic weight gain (IDWG) in patients on chronic hemodialysis., Methods: Searches were run from 1975 to January 2022 on Medline, PubMed, Web of Science, and the Cochrane Library. The search terms included "hemodialysis/haemodialysis" AND "adherence" AND ("fluid intake" OR "water intake") AND ("weight gain" OR "interdialytic weight gain" OR "IDWG") AND "patient-level interventions. Randomized controlled studies were eligible if they were in English, published in a peer-reviewed journal and regarded adults patients with on chronic hemodialysis for at least 6 months; compared educational/cognitive and/or counseling/behavioral or psychological interventions to no intervention on interdialytic weight gain. Outcome of interest was interdialytic weight gain. The review was registered on the International Prospective Register of Systematic Reviews in Health and Social Care (PROSPERO, ID number CRD42022332401)., Results: Eighteen studies (1759 patients) were included in the analysis. Compared to the untreated group, educational/cognitive and/or counseling/behavioral interventions significantly reduced interdialytic weight gain with a pooled mean difference of - 0.15 kg (95% CI - 0.26, 30-0.05; P = 0.004). On the other hand, psychological/affective interventions reduced interdialytic weight gain with a pooled mean difference of - 0.26 kg (95% CI - 0.48, - 0.04; P = 0.020)., Conclusions: Educational/cognitive, counseling/behavioral or psychological/affective interventions significantly reduced the interdialytic weight gain in patients on chronic hemodialysis, although such reduction did not appear to be clinically relevant on hard outcomes., (© 2022.

Patients with head and neck cancer (HNC) are frequently malnourished at the time of diagnosis and before beginning treatment. In addition, chemoradiotherapy causes or exacerbates symptoms such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea, and vomiting, with consequent worsening of malnutrition. If obstructing cancer and/or mucositis interferes with swallowing, enteral nutrition should be delivered by a nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG). To review studies comparing NGT's and PEG's nutrition outcomes, survival, hospitalizations, radiotherapy interruptions, quality of life, and swallowing function. Two hundred fifty publications were identified via electronic databases. 26 manuscripts that met the inclusion criteria were included for analysis. We divided the analysis in two sections: (1) comparison of enteral nutrition through NGT or PEG and (2) comparison of reactive PEG (R-PEG) and prophylactic PEG (P-PEG). They have comparable nutrition outcomes, number of radiotherapy interruptions, survival, and quality of life, whereas swallow function seems better with NGT. PEG may be associated with major complications such as exit-site infection, malfunction, leakage, pain, pulmonary infection, and higher costs. Nevertheless, NGTs dislodged more often; patients find NGTs more inconvenient; NGTs may cause aspiration pneumonia; P-PEG and R-PEG have similar nutrition outcomes, number of radiotherapy interruptions, and survival. PEG does not have better nutrition, oncologic, and quality-of-life outcomes than NGT. Prophylactic feeding through NGT or PEG, compared with reactive feeding, does not offer significant advantages in nutrition outcomes, radiotherapy interruptions, and survival. However, the number of prospective randomized studies on this topic is limited; consequently, definitive conclusions cannot be drawn. Further adequate, prospective randomized studies are needed., (© 2022 American Society for Parenteral and Enteral Nutrition.)

Fatigue is still present in up to 40-50% of kidney transplant recipients (KTR), the results of studies comparing the prevalence among patients on hemodialysis (HD) and KTR led to conflicting results. Fatigue correlates include inflammation, symptoms of depression, sleep disorders and obesity. Fatigue in KTR leads to significant functional impairment, it is common among KTR poorly adherent to immunosuppressive therapy and is associated with a serious deterioration of quality of life. The following databases were searched for relevant studies up to November 2020: Medline, PubMed, Web of Science and the Cochrane Library. Several studies have compared the prevalence and severity of fatigue between KTR and hemodialysis or healthy patients. They have shown that fatigue determines a significant functional deterioration with less chance of having a paid job and a significant change in quality of life. The aim of the review is to report methods to assess fatigue and its prevalence in KTR patients, compared to HD subjects and define the effects of fatigue on health status and daily life. There is no evidence of studies on the treatment of this symptom in KTR. Efforts to identify and treat fatigue should be a priority to improve the quality of life of KTR.

Introduction: The present study aimed to determine the variables that are associated with a longer dialysis recovery time (DRT) and to define the relationship that exists between DRT and the ultrafiltration rate (UFR) in prevalent chronic hemodialysis (CHD) patients., Methods: We studied 210 prevalent CHD of 5 hemodialysis units in Central Italy. Patients were invited to answer to the question: "How long does it take you to recover from a dialysis session?" Answers to this question were subsequently converted into minutes. Demographic, clinical and laboratory parameters were recorded for each patient as well as the UFR (mL/kg/h), the dialysate sodium concentration and temperature., Results: Median DRT was 180 min (60-420). Ninety five (45%) patients had a DRT ≥ the median value. Mean UFR was 9.2 ± 3.0 mL/kg/h. Patients with a lower DRT had a less prevalent disability in the instrumental activities daily living, had a higher UFR, and a lower dialysate temperature, as compared with subjects with higher DRT. According to the logistic regression model, UFR was associated with a DRT below the median (i.e., 180) in the unadjusted model (OR 1.12; 95% CI 1.02-1.23; p = 0.019), after adjusting for age and sex (OR 1.11; 95% CI 1.01-1.22; p = 0.025), and in the fully adjusted model (OR 1.11; 95% CI 1.04-1.22; p = 0.040). UFR increase was associated with increasing probability of DRT below the median (p for trend = 0.035). The highest tertile of DRT was associated with UFR below the mean value (i.e., 9.2 mL/kg/h) in multinomial logistic regression having the lowest DRT tertile as reference. DRT was significantly lower in patients with UFR > 13 mL/kg/h than in patients with UFR 10-13 or < 10 mL/kg/h., Conclusion: DRT is inversely associated with UFR in CHD patients. Whether a high UFR should be recommended to reduce the DRT needs to be elucidated through an adequate prospective randomized study., (© 2018 S. Karger AG, Basel.)

Purpose: Fatigue is common in end-stage renal disease patients receiving hemodialysis, reduces significantly their quality of life and is associated with all-cause and cardiac-related mortality. Unfortunately, little is known about the course of fatigue in patients on chronic hemodialysis., Methods: The Vitality Subscale of the SF-36 (SF-36 VS), Short-Form Health Survey, was administered to 45 patients in January (T1), June (T2) and November (T3) 2015., Results: The score of the SF-36 VS did not differ significantly among T1, T2 and T3. Similarly, the 1-year course of the SF-36 Vitality Subscale score did not differ significantly among T1, T2 and T3 after stratification of patients for sex, age, BMI, IADL and Charlson. Between T1 and T2, 21 out of 45 patients (46.6%) changed their fatigue status: 8 fatigued patients became not-fatigued and 13 not-fatigued patients became fatigued. Between T2 and T3, 12 out of 45 (26.6%) patients changed their fatigue status: 5 fatigued patients became not-fatigued and 7 not-fatigued patients became fatigued. Between T1 and T3, 19 out of 45 patients (42.2%) changed their fatigue status: 6 fatigued patients became not-fatigued and 13 not-fatigued became fatigued., Conclusion: The present study is the first to identify variations in fatigue status among patients on chronic hemodialysis during 1-year course. These findings suggest to frequently assess the presence and severity of fatigue in patients on chronic hemodialysis.

Frailty is a geriatric syndrome characterized by multi system dysregulation. It has been suggested that chronic inflammation may be involved in the pathogenesis of frailty. No study so far has identified accurate, specific and sensitive molecular biomarkers for frailty. High-temperature requirement serine protease A1 (HtrA1) is a secreted multidomain serine protease implicated in the inhibition of signaling of active transforming growth factor-β (TGF-β)1, a cytokine which has an important anti-inflammation role. The aim of the present study was to investigate the association of circulating levels of HtrA1 with frailty in a sample of older adults. The study was performed in 120 older adults aged >65years and admitted to a geriatric outpatient clinic. The frailty status of participants was assessed by both the Fried's criteria (physical frailty, PF) and a modified Rockwood's frailty index (FI). Plasma HtrA1 concentration was measured using commercial ELISA kit. Frailty was identified in 61/120 participants (50.8%) using PF, and in 60/118 subjects (50.8%) using FI. Plasma levels of HtrA1 were significantly higher in individuals classified as frail according to PF (75.9ng/mL, 95% CI 67.4-85.6) as compared with non-frail participants (48.4ng/mL, 95% CI 42.5-54.6, p<0.001). A significant association was also observed between frailty, assessed by FI, and HtrA1 levels (72.2ng/mL, 95% CI 63.4-82.3, vs. 50.4ng/mL, 95% CI 44.3-58.0, p<0.001). These associations were confirmed after adjusting for potential confounders. This study demonstrates for the first time the association of plasma levels of HtrA1 with frailty status. Future investigations are needed to validate the potential value of HtrA1 as possible biomarker for frailty., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background: Functional impairment is associated with adverse outcomes in older people, as well as in patients on chronic hemodialysis. The aim of the present study was to determine the characteristics associated with functional impairment in chronic hemodialysis, and to evaluate if functional impairment represents a risk factor for reduced survival in chronic hemodialysis., Methods: All 132 chronic hemodialysis referring to the Hemodialysis Service of the Catholic University, Rome, Italy between November 2007 and May 2015 were included. All patients underwent comprehensive geriatric assessment; functional ability was estimated using two questionnaires exploring independency in bathing, dressing, toileting, transferring, continence, feeding (ADLs), and independency in using the telephone, shopping, food preparation, housekeeping, laundering, traveling, taking medications, and handling finances (IADLs). Functional impairment was diagnosed in presence of dependence in one or more ADLs/IADLs. Mood was assessed using the 30-item Geriatric Depression Scale. Logistic regression was used to evaluate factors associated with functional impairment. The association between functional impairment and survival was assessed by Cox regression., Results: ADLs impairment was present in 34 (26 %) participants, while IADLs impairment was detected in 64 (48 %) subjects. After a follow up of 90 months, 55 (42 %) patients died. In logistic regression, depressive symptoms were associated with ADLs and IADLs impairment (OR 1.12; 95 % CI = 1.02-1.23; OR 1.16; 95 % CI = 1.02-1.33; respectively). In Cox regression, ADLs impairment was associated with mortality (HR 2.47; 95 % CI-1.07-5.67) while IADLs impairment was not associated with reduced survival (HR .80; 95 % CI-.36-1.76)., Conclusions: Functional impairment is associated with depressive symptoms; also, impairment in the ADLs represents a risk factor of reduced survival in chronic hemodialysis. These associations and their potential implication should be assessed in dedicated studies.

Background: This study aims to evaluate, in patients on chronic hemodialysis (PHD), the levels of endotoxin through a chemiluminescent bioassay based on the oxidative burst reaction of activated neutrophils to complement coated LPS-IgM immune complexes and define the variables possibly correlated., Methods: In 61 PHD, we measured serum endotoxin activity (EA) with the Endotoxin Activity Assay (EAA™) and we defined the possible association with demographic, clinical and laboratory variables., Results: Mean serum EA was 0.43 ± 0.26 UI. EA was low (<0.40) in 29 patients (47.5%), intermediate (0.40-0.60) in 14 (23%) and high (>0.60) in 18 (29.5%). A significant exponential relationship was detected between EA and serum interleukin-6 (IL-6) levels (r = 0.871). At the multiple regression analysis, intermediate-high EA was directly associated only with serum IL-6 levels. In a second model of multiple regression analysis without the variable serum IL-6 levels, intermediate-high EA was directly associated with constipation and serum troponin levels and inversely associated with serum albumin and the monthly number of sevelamer tablets., Conclusions: A high percentage of PHD has intermediate or high EA. Intermediate-high EA is significantly associated with serum IL-6 levels., (© 2016 S. Karger AG, Basel.)

Aim: Data on the outcome of chronic kidney disease (CKD) patients who are hospitalized and start unplanned urgent haemodialysis (HD) are lacking. This prospective, longitudinal, observational study aimed to define the hospital mortality rate and associated factors in CKD patients who start unplanned urgent HD., Methods: Between January 2003 and December 2009, all patients with CKD who were hospitalized, diagnosed with ESRD and started unplanned urgent haemodialysis at Haemodialysis Service of the Catholic University of Rome, Italy were recruited. Exclusion criteria were: acute renal failure, prior history of dialysis, multiple organ failure, coma, and dementia. Hospital mortality rate was the primary outcome., Results: Three and hundred sixteen patients were studied: 99 died after 19.5 ± 27.3 days and 217 survived until discharge. Of these, 154 were prescribed chronic HD and 63 restored renal function. Patients who died were significantly older and had a higher Charlson Comorbidity Index score. The mortality rates were 51.1% in patients with 81-90 years, 37.8% with 71-80 years, 34.1% with 61-70 years and 13.9% with age ≤60 years. Logistic regression analysis showed that age only was an independent risk factor for all-cause mortality., Conclusions: In CKD patients who need hospitalization and start unplanned urgent haemodialysis the mortality is very high and significantly related to age., (© 2015 Asian Pacific Society of Nephrology.)

Frailty is a condition of vulnerability that carries an increased risk of poor outcome in elder adults. Frail individuals show fatigue, weight loss, muscle weakness, and a reduced physical function, and are known to frequently experience disability, social isolation, and institutionalization. Identifying frail people is a critical step for geriatricians to provide timely geriatric care and, eventually, to improve the quality of life in elderly. The aim of the present study is to investigate the association between frailty status and micronucleus (MN) frequency, a known marker of genomic instability, in a sample of elder adults. Several clinical features were evaluated and their possible association with MN frequency was tested. Criteria proposed by Fried were used to identify frail subjects. Overall, 180 elder adults entered the study, 93 of them (51.7%) frail. No association between MN frequency and frailty status was found under the specific conditions tested in this study (mean ratio=1.06; 95% CI 0.96-1.18). The inclusion of MN frequency in the Fried's frailty scale minimally improved the classification of study subjects according to the multidimensional prognostic index (MPI). The presence of genomic instability in the ageing process and in most chronic diseases, demands further investigation on this issue., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Background: Little is known about the correlation between fatigue and survival in patients on chronic hemodialysis and whether fatigue is an independent predictor of outcome above and beyond the effects of depression. The aim of the present study was to determine if fatigue is a predictor of mortality in patients on chronic hemodialysis (CHP) and if this occurs independently of the symptoms of depression., Methods: CHP referring to the Hemodialysis Service of the Università Cattolica of Rome, Italy between November 2007 and January 2015 were studied. Demographic, clinical, and laboratory data were recorded for each patient at the moment of the inclusion in the study. Fatigue levels were assessed in patients using the Vitality Scale of SF-36 (SF-36 VS), functional ability by the activities of daily living (ADL) and instrumental activities of daily living (IADL), depressive symptoms through the Geriatric Depression Scale (GDS), cognitive function using the Mini Mental State Examination (MMSE), and comorbidity through the Charlson Comorbidity Index (CCI). Patients were grouped into four groups (quartiles): Quartile 1 (Q1), >65; Q2, ≥50 to <65; Q3, ≥35 to <50; Q4, <35., Results: We studied 126 patients: 11 were transplanted and 53 died. Patients who later died were older and had a worse cognitive performance, higher CCI and GDS scores, lower ADL, IADL and SF-36 VS scores, lower serum creatinine and albumin levels. Kaplan-Meier survival was significantly lower in Q4 than in Q1 (p = 0.0001). According to Cox regression analysis, higher fatigue (Q4) was associated with a higher risk of mortality (HR, 95% CI: 5.29, 2.2-12.73)., Conclusion: Fatigue is associated with an increased risk of mortality in CHP, with the relationship independent of symptoms of depression. Fatigue should be assessed routinely and may be a potential target of interventions that aim to reduce mortality in CHP., (© 2015 S. Karger AG, Basel.)

Introduction: In the last decades, life expectancy of persons with Down syndrome (DS) has dramatically increased and it is estimated that they will be living as long as the general population within a generation. Despite being included among the progeroid syndromes, because of the presence of features typically observed in older adults, DS is still regarded as a disease of pediatric interest. Because limited knowledge is available on the clinical characteristics of adults with DS, this study aimed to assess clinical and non-clinical features of this population and to describe similarities to the geriatric population., Methods: In this study, we described 60 adults with DS evaluated at the Day Hospital of the Geriatric Department of the Policlinico A. Gemelli, Università Cattolica del Sacro Cuore in Rome. Individuals were assessed through a standardized protocol., Results: The mean age of study participants was 38 years (range, 18-58 years) and 42 (70.0%) were women. Geriatric conditions were highly prevalent: severe cognitive impairment was diagnosed in 39 (65.0%) participants, behavioral symptoms were present in 25 (41.7%), and functional impairment in 23 (38.3%). Six (10.0%) participants lived in institutions and 11 (18.3%) were diagnosed as obese. The mean number of drugs used was 2.4; use of psychotropic drugs was highly prevalent. The most common chronic diseases were thyroid problems (44, 73.3%), followed by mood disorders (19, 31.7%), osteoporosis (18, 30.0%), and cardiac problems (10, 16.7%). Geriatric conditions and chronic diseases were more prevalent among participants aged ≥40 years., Conclusion: Several similarities between older adults and adults with DS were observed. Comorbidities, geriatric conditions, cognitive and functional deficits, and social problems are highly prevalent in both populations, contributing to the high complexity of these patients' assessment and treatment.

Background: Telomere shortening in peripheral blood mononuclear cells (PBMCs) has been associated with biological age and several chronic degenerative diseases. However, the relationship between telomere length and sarcopenia, a hallmark of the aging process, is unknown. The aim of the present study was therefore to determine whether PBMC telomeres obtained from sarcopenic older persons were shorter relative to non-sarcopenic peers. We further explored if PBMC telomere length was associated with frailty, a major clinical correlate of sarcopenia., Methods: Analyses were conducted in 142 persons aged ≥65 years referred to a geriatric outpatient clinic (University Hospital). The presence of sarcopenia was established according to the European Working Group on Sarcopenia in Older People criteria, with bioelectrical impedance analysis used for muscle mass estimation. The frailty status was determined by both the Fried's criteria (physical frailty, PF) and a modified Rockwood's frailty index (FI). Telomere length was measured in PBMCs by quantitative real-time polymerase chain reaction according to the telomere/single-copy gene ratio (T/S) method., Results: Among 142 outpatients (mean age 75.0 ± 6.5 years, 59.2% women), sarcopenia was diagnosed in 23 individuals (19.3%). The PF phenotype was detected in 74 participants (52.1%). The average FI score was 0.46 ± 0.17. PBMC telomeres were shorter in sarcopenic subjects (T/S = 0.21; 95% CI: 0.18-0.24) relative to non-sarcopenic individuals (T/S = 0.26; 95% CI: 0.24-0.28; p = 0.01), independent of age, gender, smoking habit, or comorbidity. No significant associations were determined between telomere length and either PF or the FI., Conclusion: PBMC telomere length, expressed as T/S values, is shorter in older outpatients with sarcopenia. The cross-sectional assessment of PBMC telomere length is not sufficient at capturing the complex, multidimensional syndrome of frailty.

Background: Cognitive impairment is a common finding in end-stage renal disease patients on chronic hemodialysis, but data on the associated factors are still scanty., Aims: The present study evaluated the association between cognitive function and left ventricular systolic function in hemodialysis patients., Methods: We enrolled 72 patients admitted to the Hemodialysis Unit of the Catholic University, Rome. Cognitive performance was evaluated using the Mini Mental State Examination (MMSE); a cutoff of 24 was used to diagnose cognitive impairment. Left ventricular ejection fraction (LVEF) was assessed by echocardiography. Multivariable linear and logistic regressions were adopted to assess the adjusted association between cognitive performance and LVEF. Also, linear discriminant analysis was performed to ascertain the cutoff level of LVEF which best predicted cognitive impairment., Results: Cognitive impairment was found in 37 (51 %) patients. According to linear regression, MMSE was independently associated with LVEF (B = 0.06; 95 % CI = 0.01-0.12; P = 0.040). Logistic regression confirmed the inverse association between LVEF and cognitive impairment (OR = 0.87; 95 % CI = 0.78-0.98; P = 0.022). In linear discriminant analysis, the LVEF cutoff level that best predicted cognitive impairment was ≤51 %., Conclusion: Cognitive impairment is a common finding in hemodialysis patients. Even mildly depressed LVEF is independently associated with cognitive impairment. This association and its potential therapeutic implications should be assessed in dedicated studies.

The occurrence of several geriatric conditions may influence the efficacy and limit the use of drugs prescribed to treat chronic conditions. Functional and cognitive impairment, geriatric syndromes (i.e. falls or malnutrition) and limited life expectancy are common features of old age, which may limit the efficacy of pharmacological treatments and question the appropriateness of treatment. However, the assessment of these geriatric conditions is rarely incorporated into clinical trials and treatment guidelines. The CRIME (CRIteria to assess appropriate Medication use among Elderly complex patients) project is aimed at producing recommendations to guide pharmacologic prescription in older complex patients with a limited life expectancy, functional and cognitive impairment, and geriatric syndromes, and providing physicians with a tool to improve the quality of prescribing, independent of setting and nationality. To achieve these aims, we performed the following: (i) Existing disease-specific guidelines on pharmacological prescription for the treatment of diabetes, hypertension, congestive heart failure, atrial fibrillation and coronary heart disease were reviewed to assess whether they include specific indications for complex patients; (ii) a literature search was performed to identify relevant articles assessing the pharmacological treatment of complex patients; (iii) A total of 19 new recommendations were developed based on the results of the literature search and expert consensus. In conclusion, the new recommendations evaluate the appropriateness of pharmacological prescription in older complex patients, translating the recommendations of clinical guidelines to patients with a limited life expectancy, functional and cognitive impairment, and geriatric syndromes. These recommendations cannot represent substitutes for careful clinical consideration and deliberation by physicians; the recommendations are not meant to replace existing clinical guidelines, but they may be used to help physicians in the prescribing process.

Objective: Intradialytic hypotension (IDH) is common in patients on chronic hemodialysis, but knowledge on determinants is still unclear. The present study aims at evaluating the association between IDH and dialytic age (DA) in patients on chronic hemodialysis., Methods: Between January 2012 and January 2013, 82 patients on chronic hemodialysis for at least 1 year were screened for inclusion in the present study. Of these, 14 were excluded because of advanced heart failure (n.9), history of alcohol/substance abuse (n.1), diagnosis of dementia (n.2), actual instability of clinical conditions requiring hospitalization (n.2). IDH was defined as a decrease in systolic blood pressure ≥20 mmHg or a decrease in mean arterial pressure (MAP) by 10 mmHg associated with clinical events and need for nursing interventions. The number of IDH episodes in 10 consecutive hemodialysis sessions was recorded for each patient. Linear and logistic regressions were adopted to assess the adjusted association between IDH and DA., Results: The mean DA was 92 ± 81. Eleven patients (16%) experienced IDH. DA was associated with IDH (OR = 1.01; 95% CI = 1.01-1.02; p = 0.048), after adjusting for potential confounders. DA was associated with the numbers of IDH events in the unadjusted model (B = 0.02; 95% CI = 0.01-0.03; p = 0.042), after adjusting for age and sex (B = 0.01; 95% CI = 0.01-0.03; p = 0.042) as well as in the multivariable model (B = 0.02; 95% CI = 0.01-0.05; p = 0.045)., Conclusion: DA is associated with an increased probability of IDH and with increased number of IHD events. Studies are needed to understand the underlying factors of such an association.

Purpose: Appetite in patients on chronic hemodialysis (HD) may be constantly very good/good or fair/poor or may fluctuate up and down over time. When constantly fair/poor, appetite has been shown to be associated with older age, more comorbidities, and more hospitalizations; however, it is unknown if it predicts survival. The aim of the present study was to assess appetite monthly for 6 months in patients on chronic HD and to determine if the course of appetite over time predicts mortality., Methods: Ninety-two HD patients were evaluated at baseline for appetite, nutritional and inflammatory markers, comorbid conditions, and Charlson's comorbidity index. Appetite assessment was repeated monthly for 6 consecutive months. Survival in relation with the course of appetite over time was determined., Results: Appetite was constantly very good/good in 45 patients (Group 1), fair/poor/very poor in 30 (Group 2), and fluctuated in 17 (Group 3). Twenty-seven (29.3 %) patients died after a mean period of 28 ± 13 months. Overall, the mean survival time was 42.1 ± 1.2 months. For Groups 1, 2, and 3, the mean survival time was 46.1 ± 0.92, 37.9 ± 2.5, and 39.1 ± 3.7 months, respectively (p < 0.0001). After multivariate logistic regression analysis, the course of appetite over time was not found to be an independent risk factor for mortality., Conclusions: The course of appetite over time does not seem to predict mortality in patients on chronic hemodialysis. Considering that the study included a relatively small number of patients, larger similar studies are desirable.

Background: The aim of this study was to evaluate the relationship among time of recovery after hemodialysis (TIRD) and the demographic, social, clinical and laboratory characteristics of hemodialysis patients of a Mediterranean country., Methods: One hundred hemodialysis patients were invited to answer the following question: "How long does it take you to recover from a dialysis session?" Demographic, clinical (Charlson Comorbidity Index [CCI], Mini-Mental State Examination [MMSE] and Geriatric Depression Scale [GDS]) and laboratory variables were recorded, and fatigue qualities (FQs) were assessed through 5 questions: Do you feel tired much of the time? (general); Do you feel that life is empty? (emotional); Do you have trouble concentrating? (cognitive); Do you have difficulty sleeping? (sleepiness); Do you have muscle weakness? (weakness); and Do you feel full of energy? (lack of energy)., Results: The means ± SD of TIRD was 205.5 ± 198.6 minutes: 79 patients reported a TIRD

Background: Prescribing pharmacological treatment for hospitalized older patients represents a challenge for physicians. In particular, hospitalized older adults present with acute and chronic diseases, which may require multiple treatments and increase their susceptibility to adverse drug reactions. Patterns of drugs use have rarely been investigated in these patients., Objective: To describe patterns of drugs use among hospitalized older adults participating in the CRiteria to assess Appropriate Medication use among Elderly complex patients (CRIME) project., Methods: We performed a cross-sectional multicentre study based on data from the CRIME project, a study performed in geriatric and internal medicine acute care wards of 7 Italian hospitals. The only two exclusion criteria were: age < 65 years old and unwillingness to participate in the study. Participants were assessed at hospital admission and followed until discharge., Results: Mean (Standard Deviation) age of 1123 participants was 81.5 (7.4) years, with 629 (56%) being women and 572 participants (51%) were admitted from Emergency Room. Mean length of stay was 11.2 (6.7) days. Mean number of drugs used greatly varied before (6.2, SD 3.2), during (10.6, SD 5.6) and after (7.1, SD 3.1) hospitalization. No difference in the number of drugs used during hospital stay was observed across age groups. During hospital stay, drugs for acid related disorders (77.9%) and antithrombotic agents (76.8%) were the most commonly used drugs, followed by drugs acting on the renin-angiotensin system (58.0%) and diuretics (57.1%). Very common was the use of psycholeptics (34.3%) and psychoanaleptics (22.4%)., Conclusion: Use of multiple drug treatments is common in hospitalized older adults and hospitalization is associated with a substantial increment in the number of drugs used, with no differences across age groups.

We aimed to assess the relationship among fatigue qualities (FQ) and the association of FQ with various characteristics of chronic hemodialysis (HD) patients. In 68 HD patients, we assessed the Charlson Comorbidity Index (CCI), the Geriatric Depression Scale score (GDS), the Mini Mental Status Examination (MMSE), and measured the laboratory parameters. In addition, patients answered to six questions about FQ (Tiredness: Do you feel tired much of the time? Emotional: Do you feel that life is empty? Cognitive: Do you have trouble concentrating? Sleepiness: Have you had difficulty sleeping in the past month? Weakness: Have you had muscle weakness in the past month? Lack of energy: Do you feel full of energy?). At least one FQ was reported by 62 patients. Muscle weakness (61.7%) was the most frequent and cognitive fatigue (22%) the least. Physical FQ were all more common than the mental ones. Correlation between the two mental FQ (emotional and cognitive) was 0.381 (p = 0.002). Six patients reported none of the FQ, 20 one FQ, 13 two FQ, and 29 three or more FQ. CCI and GDS were associated with all FQ and MMSE with all FQ but sleepiness. Patients reporting ≥3 FQ were older, had more comorbidities, more symptoms of depression, and a lower MMSE score. At multivariate linear regression analysis, the GDS was the only significant predictor of the number of FQ. HD patients report a variety of qualities of fatigue and the number of FQ is independently associated with symptoms of depression., (© 2012 The Authors.

Background: Little is known about the course of the symptoms of depression/anxiety and the factors predictive of such courses in hemodialysis (HD) patients. This study aimed at evaluating the possible changes of Beck Depression Inventory (BDI) and Hamilton Anxiety Rating Scale (HARS) over time, and factors associated with such changes in HD patients., Methods: We screened 110 patients for study participation. Of these, 30 were excluded because of dialytic vintage <6 months, alcohol/substance abuse, inability to answer to the questionnaires, diagnosis of psychotic or neurological disorders or recent stressful life events. Eighty patients were included in the study and BDI, HARS, Charlson Comorbidity Index, SF-36 Vitality Subscale, Mini-Mental State Examination (MMSE), routine laboratory parameters, C-reactive protein (CRP) and interleukin-6 were measured at baseline. The 18-month course of BDI and HARS was measured in patients with baseline BDI ≤14., Results: At baseline, 42 patients had BDI >14 and 38 patients ≤14. In patients with BDI ≤14, the BDI decreased/remained stable in 19 and increased in 19. Patients with increased BDI had lower baseline MMSE (22.6 ± 2.6 vs. 25.9 ± 2.7, p=0.004) and higher baseline serum CRP (6.07 ± 4.2 vs. 1.64 ± 1.59, p=0.003). At multivariate analysis the relationship between BDI changes and MMSE and serum CRP was statistically significant. In 25 patients, the HARS decreased/remained stable, while in 13 it increased. Characteristics of the 2 groups of patients did not differ significantly., Conclusions: In a meaningful proportion of HD patients, symptoms of depression worsen over time, and CRP and MMSE are independent predictors of such change.

The etiology of behavioral and psychiatric symptoms is generally considered to be multifactorial, and these symptoms often indicate a need for care or assistance, which may include the presence of uncontrolled pain. The aim of this cross-sectional study was to assess the association of pain with behavioral and psychiatric symptoms in a population of nursing home (NH) residents with cognitive impairment in Europe. Data are from the SHELTER project, which contains information on NH residents in 8 countries. Pain was defined as any type of physical pain or discomfort in any part of the body in the 3 days before the assessment. The mean age of 2822 cognitively impaired residents entering the study was 84.1 (standard deviation 9.1)years, and 2110 (74.8%) were women. Of the total sample, 538 residents (19.1%) presented with pain. After adjusting for potential confounders, pain was significantly and positively associated with socially inappropriate behavior (odds ratio [OR] 1.37; 95% confidence interval [CI] 1.04-1.80), resistance to care (OR 1.41; 95% CI 1.08-1.83), abnormal thought process (OR 1.48; 95% CI 1.16-1.90), and delusions (OR 1.48; 95% CI 1.07-2.03). A borderline inverse association was observed with wandering (OR 0.74; 95% CI 0.55-1.00). In conclusion, this cross-sectional study provides evidence from a large sample of frail elderly showing an association between pain and behavioral and psychiatric symptoms. Treatment models that put together assessment and treatment of pain and evaluate their effect on behavioral and psychiatric symptoms are needed., (Copyright © 2011 International Association for the Study of Pain.

Objective: Cognitive impairment is relatively common in end-stage renal disease patients on chronic hemodialysis, but the course of cognitive function deterioration in hemodialysis patients is essentially unknown. The present study aimed to evaluate if changes in Mini Mental State Examination (MMSE) over time in hemodialysis (HDP) and elderly (EP) patients differ significantly and determine the variables associated with such possible changes., Methods: In 80 HDP and 160 EP, the MMSE was assessed at baseline and after 1 year. Patients were stratified at baseline and at 1 year into three groups according to the MMSE: normal cognitive function >23; mild-moderate cognitive dysfunction: 18-23; severe cognitive dysfunction: <18. Univariate and multivariate analyses were performed to determine the variables associated with MMSE change over time, Results: One-year median reduction of MMSE was greater in HDP (from 24 to 21) than in EP (from 26 to 25) (P<.0001). A higher percentage of HDP than EP switched from normal to mild-moderate or severe MMSE group (P<.0001). At baseline, MMSE was negatively correlated with hypertension (P=.013), angina (P=.007) and Beck Depression Inventory (P=.041) and positively correlated with education (P=.017) and male gender (P=.015). No factors were found to be significantly associated with change of MMSE between baseline and month 12 in HDP., Conclusion: One-year MMSE reduction was greater in HDP that in EP. No factors were associated with MMSE reduction in HDP. However, it remains likely that cardiovascular comorbidities and low haemoglobin levels are related to such decline., (Copyright © 2010 Elsevier Inc. All rights reserved.)

Clostridia are uncommon causes of pleuropulmonary infection. Clostridial species infecting the pleuropulmonary structures characteristically cause a necrotizing pneumonia with involvement of the pleura. Most cases have iatrogenic causes usually due to invasive procedures into the pleural cavity, such as thoracentesis or thoracotomy, or penetrating chest injuries. Rarely clostridia pleuropulmonary infections are not related to these factors. The clinical course of pleuropulmonary clostridial infections can be very variable, but they may be rapid and fatal. We report a rare case of necrotizing pneumonia and sepsis due to Clostridium perfringens not related to iatrogenic causes or injuries in an 82 years old woman.
