How COVID-19 crisis influenced kidney transplant recipients in Slovakia.

OBJECTIVES: The aim of our analysis was to evaluate the impact of the COVID-19 pandemic on the procurement program and kidney transplantation in Slovakia and to identify the risk factors for a severe course of COVID-19 disease, as well as the risk factors for COVID-19 fatalities, with the focus on the parameters preceding the infection. We compared morbidity and mortality from COVID-19 before and after the spread of the alpha variant of the virus and the same among transplant (KTRs) and haemodialysis patients in Slovakia. METHODS: 305 KTRs (68.8 % males) with confirmed SARS-CoV-2 positivity were included in the multicentric retrospective analysis. The patients were split into subgroups based on the time of falling ill and their clinical course. RESULTS: The procurement program and kidney transplants in Slovakia dropped in the observed period by 28.6 % (p<0.0001) and by 33.5 % (p<0.0001) respectively. Age over 59 years (p=0.0088) and diabetes mellitus (p=0.0106) were identified as independent risk factors for severe course of the disease. Risk factors for death were the age over 59 years (p=0.0003) and graft dysfunction with CKD-EPI<0.5 mL/s (p=0.0029). The prevalence of the alpha variant in Slovakia was associated with a severe course in KTRs treated with corticoids (p=0.0273) and in graft dysfunction with CKD-EPI<0.5 mL/s (p=0.0076); the risk of death was higher in KTRs over 59 years (p=0.0173) and again with CKD-EPI<0.5 mL/s (p=0.0393). KTRs had a 3.7 times lower risk of infection compared to the haemodialysis patients (p<0.0001), with mortality of 9.8 % vs 30 % (p<0.0001). CONCLUSION: The procurement and transplant program is sustainable even during a pandemic, provided that measures are set up quickly. Morbidity and mortality from COVID-19 in KTRs was comparable to the situation in EU countries. Patients in the haemodialysis program had a worse prognosis (Tab. 5, Fig. 1, Ref. 21) Keywords: COVID-19, kidney transplantation, dialysis, immunosuppression, obesity, diabetes mellitus.

Plasma neurofilament light chain levels are predictors of disease activity in multiple sclerosis as measured by four-domain NEDA status, including brain volume loss.

BACKGROUND: The research is focused on sensitive biomarkers in multiple sclerosis (MS). OBJECTIVE: The aim of the study was to assess the relationship between plasma neurofilament light chain (pNfL) and disease activity as defined by the concept NEDA (no evident disease activity), including brain volumetry, in a cohort of MS patients treated with disease-modifying treatment (DMT). METHODS: Levels of pNfL (Single Molecule Array (SIMOA) technology) were examined in 95 RRMS (relapsing-remitting multiple sclerosis) patients and analyzed in relationship to NEDA-3 status and NEDA-BVL (brain volume loss; NEDA-3 extended by brain volumetry) during the last 12 months. The statistical model was developed using logistic regression analysis, including the independent variables: demographic, clinical, and magnetic resonance imaging (MRI) data. Dependent variables were NEDA-3 and NEDA-BVL status. RESULTS: The mean age of the study participants (n = 95, 62% females) was 37.85 years (standard deviation (SD) = 9.62) and the median disability score was 3.5 (2.5-4.1). Receiver operating characteristics (ROC) analysis showed that pNfL predicts NEDA-3 (the sensitivity and specificity of the model were 92% and 78%, respectively, p < 0.001) and NEDA-BVL status (the sensitivity and specificity were 80% and 65%, respectively, p < 0.001). CONCLUSION: The results show that pNfL levels are a useful biomarker of disease activity determined by NEDA-BVL status, including brain MRI-volumetry in patients with RRMS.

Neurofilament Light Chain Levels Are Associated with Disease Activity Determined by No Evident Disease Activity in Multiple Sclerosis Patients.

INTRODUCTION: There is a need for blood biomarkers of disease activity in multiple sclerosis (MS). The aim of the study was to assess the relationship between plasma neurofilament light chain (pNfL) and disease activity as defined by the concept three-domain no evident disease activity (NEDA-3). METHODS: Levels of pNfL (SIMOA) were examined in 159 MS patients and analyzed in relationship to NEDA-3 status (absence of relapse, disability score worsening, and brain magnetic resonance activity) during the last 12 months. The accuracy of the proposed model was evaluated by calculating the area under the receiver operating characteristics (ROC) curve. From the pNfL cutoff, we evaluated the NEDA-NfL status (no relapse, no Expanded Disability Status Scale [EDSS] worsening, and pNfL below the cutoff value). RESULTS: Levels of pNfL were significantly higher in MS patients than in healthy controls (p <  0.001). From a total of 159 patients, 80 (50.3%) achieved NEDA-3 status, while 79 (49.7%) patients showed evident disease activity (EDA) status. pNfL were significantly lower in the NEDA-3 group than in the EDA group (pNfL mean 7.06 pg/mL [standard deviation (SD) 2.37] vs. pNfL mean 13.04 pg/mL [SD 7.07]) (p < 0.001). ROC analysis showed that pNfL predicts NEDA-3 status (sensitivity and specificity were 80.5 and 72.7%, respectively, p < 0.001), and NEDA-NfL predicts NEDA-3 status (sensitivity and specificity were 97.1 and 82.9%, respectively, p < 0.001). CONCLUSION: The results show that pNfL levels are a useful biomarker of disease activity determined by NEDA status in patients with MS and could be an alternative to brain magnetic resonance investigation.

Is Poor Sleep Quality Associated With Greater Disability in Patients With Multiple Sclerosis?

Poor sleep is a serious burden for patients with multiple sclerosis (MS). The aim of this study is to assess whether the association between sleep quality and disability in MS patients is direct or mediated by depression, pain, and fatigue. We collected data from 152 patients with MS who filled out the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, the Multidimensional Fatigue Inventory and one item of the Short Form-36 regarding pain. The relationship between poor sleep and disability was found to be indirect, mediated by depression (p < 0.05), pain (p < 0.001) and physical fatigue (p < 0.01). Treatment of sleep disturbances may have beneficial effects beyond improving sleep. It may reduce depression, pain, and physical fatigue, which in turn may lessen disability.

EU questionnaire to screen for obstructive sleep apnoea validated in Slovakia.

OBJECTIVE: Obstructive sleep apnoea syndrome (OSAS) associated with daytime sleepiness (DS) contributes to a higher incidence of motor vehicle accidents. Validation of fitness to drive in driving license applicants, with special concern regarding OSAS accompanied by excessive DS, became mandatory under new EU legislation in January 2016. The aim of the study was to translate and validate the recommended questionnaire to screen for OSAS (Q-OSAS) in the Slovak population. No data on any Q-OSAS validation has previously been published. METHODS: The translated Q-OSAS was administered to 311 Slovak patients prior to a planned overnight polysomnography. The diagnostic accuracy of the Q-OSAS in OSAS with an apnoea-hypopnoea index of 15 or more/h of sleep was evaluated by calculating the area under the ROC curve. RESULTS: The sensitivity and specificity of the cut-off at 10 points for the Q-OSAS was 57% and 67%, respectively, with an increase of sensitivity and a decrease of specificity with a lowering of the cut-off values. Excluding the Epworth Sleepiness Scale (ESS) score from the final statistics yielded the best sensitivity (77%), specificity (50%), and an area under the ROC curve (0.637) for the cut-off value of 8 points (an equivalent of 10 points with the full version of the Q-OSAS). CONCLUSION: The Q-OSAS is an appropriate screening tool to facilitate the screening of subjects potentially at risk from moderate and severe OSAS. A modified two-step interpretation of the Q-OSAS in Slovakia yielded the best sensitivity, and in the future could promote evaluation of sleepiness in sleep and wake disorders other than OSAS for fitness to drive.

Anemia has a negative impact on self-rated health in kidney transplant recipients with well-functioning grafts: findings from an 8-year follow-up study.

PURPOSE: Anemia is a predictor of mortality and of self-rated health (SRH). However, studies on the relationship between SRH and changes in hemoglobin (Hb) value over time stratified by chronic kidney disease (CKD) stages are lacking. The aim is to explore whether a change in Hb-value over time associates with SRH at up to 8-year follow-up, stratified for CKD stages. METHODS: A prospective study with a baseline measurement between the 3rd and 12th month after KT was performed on 337 consecutive patients. Demographic and clinical data were retrieved from medical records. CKD stages were estimated using the CKD-EPI formula and divided into two groups: CKD1-2 and CKD3-5. Generalized estimating equations (GEE) were performed to identify associations of SRH at follow-up in both CKD groups. RESULTS: Male gender, new-onset diabetes mellitus after KT (NODAT), a decrease in estimated glomerular filtration rate (eGFR) and Hb-value over time contributed significantly to the GEE model on SRH at follow-up in CKD1-2. For SRH at follow-up in CKD3-5, older age, male gender and chronic renal allograft dysfunction (CRAD) contributed significantly to the GEE model. CONCLUSIONS: At up to 8-year follow-up, male gender, NODAT, a decrease in eGFR and Hb-value over time are associated with poorer SRH in CKD1-2. In such patients, we suggest monitoring slight deteriorations in eGFR and Hb-values. In CKD3-5, higher age, male gender and higher presence of CRAD are associated with poorer SRH at up to 8-year follow-up. In these patients, adequate treatment would slow down CRAD progression.

Longitudinal Changes in Body Composition in Patients After Initiation of Hemodialysis Therapy: Results From an International Cohort.

OBJECTIVE: In patients with advanced kidney disease, metabolic and nutritional derangements induced by uremia interact and reinforce each other in a deleterious vicious circle. Literature addressing the effect of dialysis initiation on changes in body composition (BC) is limited and contradictory. The aim of this study was to evaluate changes in BC in a large international cohort of incident hemodialysis patients. METHODS: A total of 8,227 incident adult end-stage renal disease patients with BC evaluation within the initial first 6 months of baseline, defined as 6 months after renal replacement therapy initiation, were considered. BC, including fat tissue index (FTI) and lean tissue index (LTI), were evaluated by Body Composition Monitor (BCM, Fresenius Medical Care, Bad Homburg, Germany). Exclusion criteria at baseline were lack of a BCM measurement before or after baseline, body mass index (BMI) < 18.5 kg/m(2), presence of metastatic solid tumors, treatment with a catheter, and prescription of less or more than 3 treatments per week. Maximum follow-up was 2 years. Descriptive analysis was performed comparing current values with the baseline in each interval (delta analysis). Linear mixed models considering the correlation structure of the repeated measurements were used to evaluate factors associated with different trends in FTI and LTI. RESULTS: BMI increased about 0.6 kg/m(2) over 24 months from baseline. This was associated with increase in FTI of about 0.95 kg/m(2) and a decrease in LTI of about 0.4 kg/m(2). Female gender, diabetic status, and low baseline FTI were associated with a significant greater increase of FTI. Age > 67 years, diabetes, male gender, high baseline LTI, and low baseline FTI were associated with a significant greater decrease of LTI. CONCLUSIONS: With the transition to hemodialysis, end-stage renal disease patients presented with distinctive changes in BC. These were mainly associated with gender, older age, presence of diabetes, low baseline FTI, and high baseline LTI. BMI increases did not fully represent the changes in BC.

Ten-year all-cause mortality in hospitalized non-surgical patients based on nutritional status screening.

OBJECTIVE: Malnutrition is common in patients admitted to hospital due to acute illness and contributes to negative patient outcomes. In Slovakia there is a lack of relevant data on malnutrition in hospitalized patients, particularly based on chronic co-morbidity and survival. The aim of the present study was to explore the prevalence of malnutrition in hospitalized chronic patients, its relationship to co-morbidity and its impact on 10-year survival. DESIGN: Retrospective cohort study. SETTING: Nutritional status was estimated by Subjective Global Assessment (SGA), BMI and serum albumin level. Survival was assessed from the National Insurance Registry over a 10-year period. The association between nutritional status measured by SGA and 10-year survival controlling for age, gender, BMI and serum albumin was analysed using Cox regression. SUBJECTS: Data were taken from the medical records of 202 consecutively admitted chronic patients. Results Median age was 63·5 years; 55·4 % were males; median BMI was 25·9 kg/m2; median serum albumin level was 39·0 g/l. Based on SGA evaluation, 38·1 % did not have sufficient nutritional status (SGA classification B and C). Malnutrition was more common in patients who were older (P=0·023), with lower BMI (P<0·001), who had gastrointestinal (P=0·049) and oncologic co-morbidity (P=0·021) and lower albumin level (P=0·049). In-hospital mortality was 3 %, but during the following 10 years 52 % died. Cox regression analysis controlling for age, gender, BMI and serum albumin showed that SGA was an independent predictor of death (hazard ratio=1·55; 95 % CI 1·04, 2·32; P=0·031). CONCLUSIONS: SGA is a simple screening tool that can be routinely used in hospitalized Slovak medical patients to predict the risk of death. Improving patient nutrition could thus reduce mortality.

Seven years' mortality in Roma and non-Roma patients after coronary angiography.

BACKGROUND: Ethnicity is associated with differences in clinical course and outcomes of cardiac disease, often in association with a poorer socioeconomic position. The aim of this study was to compare the mortality after coronary angiography (CAG) of Roma and non-Roma patients matched for education and adjusted for gender and age. METHODS: In total, 816 patients were included in the study (167 Roma and 649 non-Roma). Data on socio-demographic background, disease history, use of drugs, coronary findings and type of treatment were obtained from medical records. Mortality was assessed up to seven years after CAG. Kaplan-Meier curves of mortality were plotted, and differences between the Roma and non-Roma patients were assessed using log-rank tests, matched for education and adjusted for gender and age. RESULTS: Mortality after CAG was significantly higher among Roma than non-Roma (log-rank test χ(2) = 7.59, P < 0.01) and remained so after matching for education and adjustment for gender, age, history of previous myocardial infarction and abnormal CAG (hazard ratio: 2.07, 95% confidence interval: 1.13-3.82). CONCLUSION: Mortality after CAG is higher among Roma, and this is not due to differences in age, gender or education. These results warrant further reconsideration of the management of Roma cardiac patients.

The mediating effect of coping on the association between fatigue and quality of life in patients with multiple sclerosis.

Fatigue, as one of the most frequent symptoms in patients with multiple sclerosis (MS), has various adverse effects on the physical and mental health-related quality of life (PCS, MCS) of patients. The aim of this study was to explore whether coping mediates the relationship between fatigue and PCS and MCS. We collected data from 154 consecutive MS patients (76.0% women; mean age 40.0 ± 9.9). Patients completed the Short-Form Health Survey (SF-36), the multidimensional fatigue inventory (MFI-20) and the coping self-efficacy scale. The mediating effect of coping was analysed using linear regressions and the Sobel z-test. In PCS significant mediation was found in some of the fatigue dimensions (general, physical and reduced Motivation), while in MCS, it was significant in all dimensions. These results can be implemented into educational programmes for patients, their caregivers or physicians, and can also be helpful in the treatment process.

Solitary functioning kidney in children--a follow-up study.

BACKGROUND/AIMS: This study aims to assess the cumulative incidence of elevated albuminuria, hypertension and decreased estimated glomerular filtration rate (eGFR) to identify possible renal injury in children with SFK. METHODS: Forty-two children with SFK (23 boys; 27 congenital) were included in a prospective follow-up study. Blood pressure, albuminuria and eGFR were assessed repeatedly and the cumulative incidence rate of various forms of renal injury, overall and by type of etiology, were evaluated. Finally, renal injury-free survival was analyzed. RESULTS: Mean follow-up was until age 11.3 years (SD 6.3 years). During follow-up, 16 (38.1%) patients met the criteria for renal injury, defined as hypertension (10; 23.8%), severely increased albuminuria (3; 7.1%) and a significantly impaired eGFR (<60 ml/min/1.73 m2) (5; 11.9%) and/or use of antihypertensive or antiproteinuric medication (11; 26.2%). Children with CAKUT in SFK had a significantly higher incidence of renal injury. The median time to develop renal injury was 12.8 years. CONCLUSION: A substantial proportion of children with SFK develop renal injury during childhood, especially those with CAKUT in the SFK. Therefore, close follow-up of albuminuria, blood pressure and eGFR are warranted to identify chronic kidney disease in its early stages.

Anxiety and sense of coherence in Roma and non-Roma coronary heart disease patients.

OBJECTIVE: Morbidity and mortality among Roma due to coronary heart disease (CHD) is high, but evidence on potential psychosocial pathways is lacking. This study aimed to assess the differences in the severity of anxiety symptoms and in the sense of coherence (SOC) between Roma and non-Roma CHD patients, crude and adjusted for age, sex, functional status and socio-economic status (SES). DESIGN: We examined 607 CHD patients (mean age 58.0 ± 7.4, 28.7% female) scheduled for coronary angiography, 98 (16.1%) of whom were Roma. Anxiety symptoms were measured using the Hospital Anxiety and Depression Scale and SOC using the 13-item Orientation to Life Questionnaire. Data were analysed using hierarchical regression. RESULTS: Roma ethnicity was associated with more severe anxiety (B = 1.89; [95% confidence interval (CI) = 0.79; 2.98]) adjusted for age, sex, functional status and SES. Roma ethnicity was also associated with lower SOC (B = -4.77; [95% CI = -7.85; -1.68]) adjusted for age, sex and functional status. The latter association lost statistical significance after adjustment for SES. CONCLUSION: Roma ethnicity is associated with more anxiety symptoms and lower SOC among CHD patients. Our findings indicate that Roma CHD patients have a worse position regarding psychosocial factors that increase mortality and thus require additional attention.

Body composition monitor assessing malnutrition in the hemodialysis population independently predicts mortality.

OBJECTIVE: Malnutrition is a known predictor of mortality in the general and hemodialysis populations. However, diagnosing malnutrition in dialysis patients remains problematic. Body composition monitoring (BCM) is currently used mainly for assessing overhydratation in hemodialysis patients, but it also offers the possibility of evaluating nutrition status. This study explored whether malnutrition diagnosed by BCM predicts mortality at up to 54 months follow-up in prevalent hemodialysis patients. DESIGN: This was a retrospective epidemiology cohort study. Dialysis patients with baseline BCM measurement between 2008 and 2013 were enrolled. The observation period was up to 54 months follow-up. SUBJECTS: A total sample consisted of 960 chronic hemodialysis participants. INTERVENTION: All data were retrieved from medical records. Nutrition status was estimated by BCM; malnutrition was diagnosed as lean tissue index less than 10% of the normal value. MAIN OUTCOME MEASURE: Cox regression was performed to identify whether low LTI predicted mortality in hemodialysis patients. RESULTS: BCM-diagnosed malnutrition (hazard ratio [HR] 1.66; 95% confidence interval [CI] 1.1; 2.44), higher age (HR 1.05; 95% CI 1.03; 1.07), longer dialysis vintage (HR 1.00; 95% CI 1.00; 1.00), central venous catheter use (HR 1.96; 95% CI 1.28; 2.99), and low serum albumin (HR 0.91; 95% CI 0.87; 0.95) contributed significantly to the Cox regression model on mortality. CONCLUSION: BCM-diagnosed malnutrition in chronic hemodialysis patients is an independent predictor of mortality at up to 54 months follow-up and is associated with a 1.66-fold higher risk of dying compared with normal nutrition status. Whether intervention (e.g., nutritional supplementation) might improve nutrition and reduce the higher risk of mortality in malnutrition patients on hemodialysis remains a challenge for future research.

Adherence in patients in the first year after kidney transplantation and its impact on graft loss and mortality: a cross-sectional and prospective study.

AIMS: To explore the predictive value of adherence to their immunosuppressive medication in kidney transplant recipients in the first year after kidney transplantation as a determinant of graft loss and mortality up to 12 years (prospective analysis) and its association with sociodemographic and medical factors and social support (cross-sectional analysis). BACKGROUND: Poor adherence to their immunosuppressive medication in kidney transplant recipients remains the leading preventable cause of poor patient outcomes. DESIGN: Prospective and cross-sectional study. METHODS: At baseline, 325 patients 3-12 months posttransplantation were invited to participate. Adherence was assessed using collateral reports - a combination of patients' self-evaluation and an estimate by their nephrologist. The patients provided sociodemographic and medical data and completed the End-Stage Renal Disease Symptom Checklist and Multidimensional scale of perceived social support. At follow-up (average 7·1 years), data on patients and graft survival were obtained. All data were collected from 2002-2013. Multinomial regression analysis and Cox regression were performed. RESULTS: A total of 297 patients (48·1 (12·8) years, 61·6% men) agreed to participate (response rate 91·4%); 67·4% were considered as fully adherent. Poor adherence was associated with higher risk of graft loss and mortality over 12 years. Female sex, higher education, higher perceived side effects of corticosteroids, better perceived cardiac and renal function and higher perceived family social support in the first year posttransplantation were associated with full adherence to immunosuppressive treatment. CONCLUSIONS: Patients with poor adherence to the immunosuppressive medication in the first year after kidney transplantation showed increased likelihood of graft loss and death over 12 years compared with the adherent patients.

Self-rated health mediates the association between functional status and health-related quality of life in Parkinson's disease.

AIMS AND OBJECTIVES: To explore whether self-rated health acts as a potential mediator in the association between functional status and health-related quality of life in Parkinson's disease. BACKGROUND: Older persons (as most patients with Parkinson's disease are) who reported poor self-rated health compared with those with excellent self-rated health were two-and-a-half times more likely to have experienced a decline in functional ability. DESIGN: Cross-sectional. METHODS: Socio-demographic and clinical data of the patients (n = 176) were obtained during a structured interview and from medical records. Functional status was measured with the Unified Parkinson's Disease Rating Scale (total score), self-rated health with the first item of the Short-Form 36-item Health Survey Questionnaire and health-related quality of life with the disease-specific questionnaire called the Parkinson's Disease Quality of Life Questionnaire-39. Multiple linear regression analyses and the Sobel test were employed to assess mediation. RESULTS: Self-rated health seems to have a mediating effect on the association between functional status and health-related quality of life. The Sobel test confirmed an indirect effect of functional status via self-rated health on health-related quality of life and showed a statistically significant indirect effect of functional status on health-related quality of life via self-rated health against the direct route without the mediator. CONCLUSIONS: Self-rated health partially mediates the deteriorating effect of functional status on health-related quality of life. RELEVANCE TO CLINICAL PRACTICE: Supportive and adaptation psychosocial intervention programmes leading to restored self-rated health may enhance the quality of life regardless of disability in Parkinson's disease.

Higher prevalence of nephropathy in young Roma females compared with non-Roma females.

OBJECTIVES: Ethnic differences in the prevalence of various chronic diseases, including end-stage renal disease, have been previously reported. Surprisingly, data focusing on the lower grade of chronic kidney disease (CKD) are scarce. Thus, the aim of this study was to explore differences in the prevalence of nephropathy between the Roma and non-Roma populations. METHODS: Data from the cross-sectional population based HepaMeta study conducted in Slovakia were used. Nephropathy was defined as: a known history of any kidney disease; or the presence of proteinuria/hematuria; or glomerular filtration rate (GFR) < 60 ml/min. The odds ratio for the prevalence of nephropathy was calculated using binary logistic regression. RESULTS: In an age-adjusted model, Roma females had OR of 1.56 for having nephropathy over non-Roma females (OR 1.56; 95% CI 1.01-2.42; p < 0.05). In addition, Roma females had a significantly lower GFR (mean difference 3.4 ml/min, t = -3.58, p < 0.001); all female patients with proteinuria were Roma. CONCLUSIONS: This cross-sectional study on the young general population found that Roma females have half-higher odds for nephropathy than non-Roma females. Therefore, to prevent risks we should focus on searching for ethnic, social and medical determinants of CKD. Interventions to decrease the incidence of CKD in the target population should also address ethnic inequalities as well as female gender.

Perceptions of healthcare providers on benefits, risks and barriers regarding intradialytic exercise among haemodialysis patients.

PURPOSE: Clinical guidelines call for the inclusion of exercise interventions in every patient's dialysis session, but these recommendations are rarely adopted. Healthcare providers play a key role in this. Therefore, the aim of this study was to explore how healthcare providers perceive the benefits, risks and barriers of intradialytic exercise (IDE). METHODS: We conducted 21 individual, semi-structured interviews with 11 nurses, 5 nephrologists, 3 training assistants and 2 managers from two dialysis centres in Slovakia. Verbatim transcripts of digitally recorded interviews were thematically analysed using MAXQDA®. RESULTS: Participants reported the benefits of IDE as improvements in patients' physical and psychosocial functioning, independence and self-efficacy, clinical profile and quality of therapy. As risks of IDE, they most frequently reported exercise-related damage to vascular access, insufficient individualization of training and musculoskeletal injuries. The presence of psychological problems among patients was reported as a major barrier for initiating and maintaining patients' exercise. Other reported barriers included limitations in financial and personnel resources of haemodialysis care. CONCLUSIONS: Safe and sustainable implementation of IDE, which might improve a patient's well-being, need to be prescribed in alignment with the patient's clinical profile, be delivered individually according to the patient's characteristics and requires adjustments in the available resources.

Hemodialysis Procedures for Stable Incident and Prevalent Patients Optimize Hemodynamic Stability, Dialysis Dose, Electrolytes, and Fluid Balance.

The demographic profile of patients transitioning from chronic kidney disease to kidney replacement therapy is changing, with a higher prevalence of aging patients with multiple comorbidities such as diabetes mellitus and heart failure. Cardiovascular disease remains the leading cause of mortality in this population, exacerbated by the cardiovascular stress imposed by the HD procedure. The first year after transitioning to hemodialysis is associated with increased risks of hospitalization and mortality, particularly within the first 90-120 days, with greater vulnerability observed among the elderly. Based on data from clinics in Fresenius Medical Care Europe, Middle East, and Africa NephroCare, this review aims to optimize hemodialysis procedures to reduce mortality risk in stable incident and prevalent patients. It addresses critical aspects such as treatment duration, frequency, choice of dialysis membrane, dialysate composition, blood and dialysate flow rates, electrolyte composition, temperature control, target weight management, dialysis adequacy, and additional protocols, with a focus on mitigating prevalent intradialytic complications, particularly intradialytic hypotension prevention.

Apathy in elderly nondemented patients with Parkinson's disease: clinical determinants and relationship to quality of life.

OBJECTIVES: To describe the prevalence and clinical determinants of apathy in elderly nondemented patients with Parkinson's disease (PD) and their relationship to quality of life (QoL). METHODS: A total of 106 nondemented elderly patients with PD were examined using the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Starkstein Apathy Scale, Hospital Anxiety and Depression Scale, Beck Depression Inventory-II, and 39-item Parkinson's disease quality of life questionnaire. RESULTS: Apathy was present in 54% of the studied population. Factors associated with apathy were higher depression scores and a lower daily levodopa equivalent dose. Longer disease duration, higher motor MDS-UPDRS subscore, and higher depression and anxiety scores, but not apathy, were found to be associated with worse QoL. CONCLUSIONS: Although apathy does not seem to be an independent predictor of worse QoL specifically in elderly patients with PD, it remains very relevant, as its presence increases caregiver burden. Both depression and potential dopaminergic treatment underdosing can be properly managed, thus potentially reducing the prevalence and severity of apathy in a proportion of the apathetic patients with PD.

Type D, anxiety and depression in association with quality of life in patients with Parkinson's disease and patients with multiple sclerosis.

PURPOSE: The present study examines the role of Type D personality, anxiety and depression in quality of life (QoL) in patients with two chronic neurological diseases--Parkinson's disease (PD) and multiple sclerosis (MS). METHODS: This cross-sectional study included 142 PD patients (73 % males; mean age 67.6 ± 9.2 years) and 198 patients with MS (32.3 % males; 38.4 ± 10.8 years). Multiple regression analyses were used to analyze the association of UDPRS (PD patients) or EDSS (MS patients), Type D personality (DS-14) and anxiety and depression (HADS) with the physical (PCS) and mental summary (MCS) of QoL, as measured by the SF-36. RESULTS: In PD patients, Type D was significantly associated with MCS only; in MS patients, Type D was significantly associated with both dimensions--MCS and PCS. After adding anxiety and depression, the importance of Type D for the QoL model dramatically decreased. Anxiety and depression were strongly associated with lower scores in MCS and PCS in both PD and MS patients. CONCLUSIONS: The actual mood of PD and MS patients--the level of anxiety or depression--might have a greater impact on patients' QoL than their personality. Further longitudinal research should focus on how the pathway consisting of personality traits, anxiety and depression, and QoL might be constructed.
