Abstract
INTRODUCTION Peritoneal dialysis (PD), as a home treatment, ensures better patient autonomy and lower intrusiveness compared to hemodialysis. However, choosing PD comes with an increased burden of responsibility that the patient may not always be able to bear, due to advanced age and deteriorating health condition. Various approaches have been explored to address this issue and mitigate its primary complications. In this study, we aim to present the ongoing PD training at-home program implemented by the Vicenza PD Center, and evaluate its impact on patients' prognoses. MATERIAL AND METHODS We enrolled 210 patients who underwent PD at Vicenza Hospital between 1 January 2019 and 1 January 2022 for a minimum of 90 days. Each patient was observed retrospectively for one year. We categorized the patients into three groups based on their level of autonomy regarding their PD management: completely independent patients; patients able to perform some parts of the PD method on their own, while the remaining aspects were carried out by a caregiver; and patients who required complete assistance from a caregiver, like in the assisted PD program (asPD). RESULTS A total of 70% of the PD population were autonomous regarding their PD therapy, 14% had an intermediate degree of autonomy, and 16% were entirely dependent on caregivers. The PD nurses performed a median of four home visits per patient per year, with a tendency to make more visits to patients with a lower degree of autonomy. All the groups achieved similar clinical outcomes. At the end of the year of observation, only 6% of the patients witnessed a decline in their autonomy level, whereas 7% demonstrated an enhancement in their level of autonomy, and 87% remained stable. CONCLUSIONS A home care assistance program ensures clinical support to a household with the purpose of improving the empowerment of the PD population and reducing the prevalence of assisted PD. Ongoing PD training at home helps patients to maintain a stable degree of autonomy and stay in their home setting, even though they present with relative attitudinal or social barriers.

Abstract
BACKGROUND Relationships between adulthood modifiable risk factors and chronic kidney disease (CKD) are well-established, but associations with childhood risk factors are unclear. This study systematically assesses the published evidence about childhood modifiable risk factors and adulthood CKD. METHODS We searched MEDLINE, EMBASE, and Web of Science to 6th May 2022. Articles were included if (1) they were population-based longitudinal studies, (2) exposures were potentially modifiable, for example through pharmacological or lifestyle modifications, including clinical conditions/measures (diabetes, blood pressure, adiposity, and dyslipidaemia); health behaviours (smoking, alcohol consumption, physical activity, fitness, and poor nutrition); and socio-economic factors (socio-economic position), and occurred during childhood (ages 2-19 years), and (3) outcome was CKD or surrogate markers of CKD in adulthood (ages 20 years or older). Three reviewers independently extracted the data. RESULTS 15,232 articles were identified after deduplication; 17 articles met the inclusion criteria, reporting childhood blood pressure (n = 8), adiposity (n = 4), type 2 diabetes (n = 1), socio-economic position (n = 1), famine (n = 1), cardiorespiratory fitness (n = 1), and a healthy lifestyle score (n = 1). The results suggested positive associations of childhood adiposity, type 2 diabetes, and low socio-economic position and cardiorespiratory fitness in females with CKD in adulthood. Findings were inconsistent on associations between childhood BP and CKD in adulthood. Childhood healthy lifestyle score and exposure to famine were not associated with risk of CKD in adulthood. CONCLUSIONS The limited evidence suggests childhood factors may contribute to the CKD risk in adulthood, particularly adiposity, type 2 diabetes, and low socio-economic position and cardiorespiratory fitness in females. Further high-quality community-based studies are needed with long-term follow-up and investigation of a broader range of modifiable risk factors.

Abstract
OBJECTIVE The purpose of the systematic review was to assess the effectiveness of remote patient monitoring (RPM) follow-up compared with standard care, for patients with chronic kidney disease (CKD) who perform dialysis at home. METHODS We conducted a systematic review in accordance with international guidelines. We performed systematic searches for publications from 2015 to 2021 in five databases (eg, Medline, Cinahl, Embase) and a search for grey literature in reference lists. Included effect measures were quality of life, hospitalisation, technical failure as the cause for transfer to a different dialysis modality, infections and time patients use for travel. Screening of literature, data extraction, risk-of-bias assessment and certainty of evidence assessment (using the Grading of Recommendations Assessment, Development and Evaluation approach) were done by two researchers. We conducted meta-analyses when possible. RESULTS Seven studies met the inclusion criteria, of which two were randomised controlled trials and five were retrospective cohort studies with control groups. The studies included 9975 participants from 5 countries, who were a good representation of dialysis patients in high-income and upper-middle-income countries. The patients were on peritoneal dialysis (six studies) or home haemodialysis (one study). There was very low certainty of evidence for the outcomes, except for hospitalisations: there was low certainty evidence from three cohort studies for fewer hospitalisation days in the RPM group. No studies included data for time patients used for travel. CONCLUSION We found low to very low certainty evidence that indicate there may be positive effects of RPM follow-up, in comparison to standard care only, for adult patients with CKD who perform dialysis at home. Offering RPM follow-up for home dialysis patients as an alternative or supplement to standard care appears to be safe and provide health benefits such as fewer hospitalisation days. Future implementation should be coupled with robust, high-quality evaluations. PROSPERO REGISTRATION NUMBER CRD42021281779.

Abstract
Background Stage 5 chronic kidney disease (CKD) patients often experience decisional conflict when faced with the selection between the initiation of dialysis and conservative care. The study examined the effects of a brief hope intervention (BHI) on the levels of hope, decisional conflict and the quality of life for stage 5 CKD patients. Methods This is a single-blinded, randomized controlled trial (ClinicalTrials.gov identifier: NCT03378700). Eligible patients were recruited from the outpatient department renal clinic of a regional hospital. They were randomly assigned to either the intervention or the control group (intervention: n = 35; control: n = 37). All participants underwent a customized pre-dialysis education class, while the intervention group received also BHI. Data were collected prior to the intervention, immediately afterwards, and one month following the intervention. The Generalized Estimating Equation was used to measure the effects in the level of hope, decisional conflict scores (DCS) and Kidney Disease Quality of life (KDQOL-36) scores. Estimated marginal means and standard errors with 95% confidence intervals of these scores were also reported to examine the within group and between group changes. Results An increase of the hope score was found from time 1 (29.7, 1.64) to time 3 (34.4, 1.27) in the intervention group. The intervention had a significant effect on the KDQOL-36 sub-scores Mental Component Summary (MCS) (Wald χ2 = 6.763, P = 0.009) and effects of kidney disease (Wald χ2 = 3.617, P = 0.004). There was a reduction in decisional conflict in both arms on the DCS total score (Wald χ2 = 7.885, P = 0.005), but the reduction was significantly greater in the control group (effect size 0.64). Conclusions The BHI appeared to increase the level of hope within the intervention arm. Nonetheless, differences across the intervention and control arms were not significant. The KDQOL-36 sub-scores on MCS and Effects of kidney disease were found to have increased and be higher in the intervention group. The DCS total score also showed that hope was associated with reducing decisional conflict. Trial Registration ClinicalTrials.gov Protocol Registration, NCT03378700. Registered July 12 2017.

Abstract
Hypertension (HTN) is common in chronic kidney disease (CKD), and it may aggravate CKD progression. The optimal blood pressure (BP) value in CKD patients is not established yet, although systolic BP ≤130 mmHg is acceptable as a target. Continuous BP monitoring is essential to detect the different variants of high BP and monitor the treatment response. Various methods of BP measurement in the clinic office and at home are currently used. One of these methods is ambulatory BP monitoring (ABPM), by which BP can be closely assessed for even diurnal changes. We conducted a non-systematic literature review to explore and update the association between high BP and the course of CKD and to review various BP monitoring methods to determine the optimal method for BP recording in CKD patients. PubMed, EMBASE, Google, Google Scholar, and Web Science were searched for published reviews and original articles on BP and CKD by using various phrases and keywords such as "hypertension and CKD", "CKD progression and hypertension", "CKD stage and hypertension", "BP control in CKD", "BP measurement methods", "diurnal BP variation effect on CKD progression", and "types of hypertension." We evaluated and discussed published articles relevant to the review objective. Before preparing the final draft of this article, each author was assigned a section of the topic to read, research deeply, and write a summary about the assigned section. Then a summary of each author's contribution was collected and discussed in several group sessions. Early detection of high BP is essential to prevent CKD development and progression. Although the latest Kidney Disease Improving Global Outcomes (KDIGO) guidelines suggest that a systolic BP ≤120 mmHg is the target toprevent CKD progression, systolic BP ≤130 mmHg is universally recommended.ABPM is a promising method to diagnose and follow up on BP control; however, the high cost of the new devices and patient unfamiliarity with them have proven to be major disadvantages with regard to this method.

Abstract
High internal phase emulsions (HIPEs), with densely packed droplets of internal phase and monomers dispersed in the continuous phase, are now an established medium for porous polymer preparation (polyHIPEs). The ability to influence the pore size and interconnectivity, together with the process scalability and a wide spectrum of possible chemistries are important advantages of polyHIPEs. In this review, the focus on the biomedical applications of polyHIPEs is emphasised, in particular the applications of polyHIPEs as scaffolds/supports for biological cell growth, proliferation and tissue (re)generation. An overview of the polyHIPE preparation methodology is given and possibilities of morphology tuning are outlined. In the continuation, polyHIPEs with different chemistries and their interaction with biological systems are described. A further focus is given to combined techniques and advanced applications.

Abstract
BACKGROUND End-Stage Renal Disease (ESRD) is the final and permanent stage of Chronic Kidney Disease (CKD). Hemodialysis (HD) is the most common treatment for CKD. To have desirable therapeutic outcomes, patients have to adhere to a specific therapeutic regimen that reduces the hospitalization rate and side-effects of HD. The present study aimed to determine the effects of the patient education program and nurse-led telephone follow-up on adherence to the treatment in hemodialysis patients. METHODS This is a randomized controlled trial in which a total of 66 patients were recruited using convenience sampling and then randomly assigned to two groups of control (n = 33) and intervention (n = 33). Data were collected using a demographic questionnaire, the laboratory results record sheet, and the End-Stage Renal Disease Adherence Questionnaire (ESRD-AQ), which included four dimensions of HD attendance, medication use, fluid restrictions, and diet recommendations. The intervention group received a patient education program and nurse-led follow-up services through telephone communication and the Short Message Service (SMS) for 3 months. All participants filled in the questionnaire before and after the intervention. Data were analyzed using IBM SPSS Statistics for Windows, version 25 (IBM Corp., Armonk, N.Y., USA). RESULTS The results showed a significant difference in the mean scores of HD attendance, medication use, fluid restrictions, and diet recommendations between the two groups immediately, 1 month, and 3 months after the intervention (p < .001). The results also indicated a significant difference in the mean scores of four dimensions during the four-time points of measurement in the intervention group (P < 0.0005). Therefore, the level of treatment adherence in the intervention group was higher than in the control group. Moreover, there was a significant difference in the mean score of laboratory values between the two groups after the intervention, except for the level of serum sodium (P = 0.130). CONCLUSION Implementation of the patient education program and nurse-led follow-up can lead to better adherence to hemodialysis in four dimensions of HD attendance, medication use, fluid restrictions, and dietary recommendations in HD patients.

Abstract
BACKGROUND Previous studies have identified retinal microvascular features associated with renal dysfunction. Biopsies are necessary to confirm kidney microvascular damage and retinal imaging may enable evaluation of microangiopathic characteristics reflecting renal changes associated with chronic kidney disease (CKD). We evaluated retinal microvascular parameters (RMPs) for associations with renal function in a cross-sectional analysis of the Northern Ireland Cohort for the Longitudinal Study of Ageing. METHODS RMPs (central retinal arteriolar/ venular equivalents [CRAE/CRVE], arteriolar to venular ratio [AVR], fractal dimension and tortuosity) were measured from optic disc centred fundus images using semi-automated software. Associations were assessed with multivariable regression analyses between RMPs and estimated glomerular filtration rate (eGFR) defined by serum creatinine (eGFRscr) and cystatin C (eGFRcys) and also CKD status characterised by eGFR < 60 mL/min/1.73m2. Regression models were adjusted for potential confounders including age, sex, diabetes, smoking status, educational attainment, cardiovascular disease, body mass index, antihypertensive medication, systolic blood pressure, triglycerides, high- and low-density lipoprotein levels. RESULTS Data were included for 1860 participants that had measures of renal function and retinal fundus images of sufficient quality for analysis. Participants had a mean age of 62.0 ± 8.5 yrs. and 53% were female. The mean eGFR for scr and cys were 82.2 ± 14.9 mL/min/1.73m2 and 70.7 ± 18.6 mL/min/1.73m2 respectively. eGFRcys provided lower estimates than eGFRscr resulting in a greater proportion of participants categorised as having CKD stages 3-5 (eGFRcys 26.8%; eGFRscr 7.9%). Multivariable regression analyses showed that increased venular tortuosity (OR = 1.30; 95%CI: 1.10, 1.54; P < 0.01) was associated with CKD stages 3-5 characterised by eGFRscr < 60 mL/min/1.73 m2. No additional associations between CKD status characterised by eGFRscr or with eGFRcys, were detected (P > 0.05). Multivariable regression failed to detect associations between CRAE, CRVE, AVR, fractal dimension or tortuosity and eGFRscr or eGFRcys (P > 0.05). CONCLUSION Increased retinal venular tortuosity was associated with CKD stages 3-5 defined by eGFRscr < 60 mL/min/1.73 m2, in an older population independent of potential confounding factors. These retinal measures may provide non-invasive microvascular assessment of associations with CKD.

Abstract
The outcomes of the elderly population on peritoneal dialysis (PD) in developing countries are less known. In this study, we intended to study the clinical characteristics and patient and technique survival of elderly patients on PD. In this study, data of 148 elderly patients with end-stage renal disease who initiated PD between January 2001 and December 2015 were collected. Baseline clinical characteristics and events during the study period were recorded. Overall patient and technique survival rates of diabetic and non-diabetic elderly patients on PD were analyzed. Around 128 patients who were initiated PD during the study period were included for final analysis. The mean age of the study group was 70.3 ± 5.1 years, and 94 (80%) were males. Among these, 79 (65.8%) had diabetes. At the end of the study period, only 20 (16.6%) patients were remained on PD. Eighty-four (70%) patients died during PD and 15 (12.5%) patients were transferred to hemodialysis during the study period. The main reasons for death were cardiovascular (56.6%) and sepsis due to peritonitis (18.8%). The mean patient survival time was 38.2 ± 2.6 months. The patient survival rates were 91.2%, 45.3%, and 22.8% at 1, 3, and 5 years, respectively. Predictors of mortality were increased serum phosphorus, peritonitis episodes, urine output <400 mL, and ultrafiltration <1000 mL/day at beginning of PD. The mean technique survival time was 92.0 ± 5.1 months. Technique survival rates at 1, 3, and 5 years were 94.8%, 85.3%, and 71.7%, respectively. None of the factors was found to be predictive of technique survival. We found no significant difference between diabetic and non-diabetic patients in terms of technique and patient survival. Mortality was higher in elderly patients on PD. Factors affecting mortality in elderly patients on PD are low urine output, low ultrafiltration at beginning of PD, high serum phosphorus, and presence of peritonitis episodes. Patient and technique survival rates were comparable between diabetic and non-diabetic elderly patients on PD.

Artificial Intelligence Prediction Model for the Cost and Mortality of Renal Replacement Therapy in Aged and Super-Aged Populations in Taiwan. J Clin Med 2019; 8:jcm8070995. [PMID: 31323939 PMCID: PMC6678226 DOI: 10.3390/jcm8070995] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 07/08/2019] [Accepted: 07/08/2019] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Prognosis of the aged population requiring maintenance dialysis has been reportedly poor. We aimed to develop prediction models for one-year cost and one-year mortality in aged individuals requiring dialysis to assist decision-making for deciding whether aged people should receive dialysis or not. METHODS We used data from the National Health Insurance Research Database (NHIRD). We identified patients first enrolled in the NHIRD from 2000-2011 for end-stage renal disease (ESRD) who underwent regular dialysis. A total of 48,153 Patients with ESRD aged ≥65 years with complete age and sex information were included in the ESRD cohort. The total medical cost per patient (measured in US dollars) within one year after ESRD diagnosis was our study's main outcome variable. We were also concerned with mortality as another outcome. In this study, we compared the performance of the random forest prediction model and of the artificial neural network prediction model for predicting patient cost and mortality. RESULTS In the cost regression model, the random forest model outperforms the artificial neural network according to the mean squared error and mean absolute error. In the mortality classification model, the receiver operating characteristic (ROC) curves of both models were significantly better than the null hypothesis area of 0.5, and random forest model outperformed the artificial neural network. Random forest model outperforms the artificial neural network models achieved similar performance in the test set across all data. CONCLUSIONS Applying artificial intelligence modeling could help to provide reliable information about one-year outcomes following dialysis in the aged and super-aged populations; those with cancer, alcohol-related disease, stroke, chronic obstructive pulmonary disease (COPD), previous hip fracture, osteoporosis, dementia, and previous respiratory failure had higher medical costs and a high mortality rate.

Abstract
The variability of molecular signatures and predictive low molecular weight markers of chronic kidney disease (CKD) in different populations are poorly understood. Thus, in a large sample with 4763 people we compare the molecular signatures and metabolites with diagnostic relevance in plasma and urine of CKD patients of different geographical origins. From an integrated model based on dynamic networks and multivariate statistics, metabolites with predictive value obtained from targeted and untargeted molecular analysis, interactions between metabolic pathways affected by CKD, and the methodological quality of metabolomic studies were analyzed. The metabolites 3-methylhistidine, citrulline, kynurenine, p-cresol sulfate, urea, and citrate presented consistent expression in all population groups. Only increased kynurenine and p-cresol sulfate in plasma samples obtained acceptable scores as CKD biomarkers, independent of geographic origin. Metabolites such as leucine, alanine, isoleucine, serine, histidine, and citrate were nodal points, indicating that protein metabolism pathways are similarly impaired in Asian, European and North American patients. Based on our integrated model, we show that the metabolome of CKD patients exhibits a strong geographic influence, leading to unique metabolic signatures. Contrary to the likelihood of molecular similarities between geographically distinct populations, metabolic convergences in protein metabolism pathways and the molecules kynurenine and p-cresol sulfate were relevant as general predictors of CKD. In general, the quality assessment indicated that the current evidence is based on research models with variable methodological quality, whose limitations described in this study should be considered in the refinement of molecular approaches.

Survival among older adults with kidney failure is better in the first three years with chronic dialysis treatment than not. Kidney Int 2018; 94:582-588. [PMID: 29803405 DOI: 10.1016/j.kint.2018.03.007] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2017] [Revised: 02/13/2018] [Accepted: 03/02/2018] [Indexed: 11/28/2022]
Abstract
Comparisons of survival between dialysis and nondialysis care for older adults with kidney failure have been limited to those managed by nephrologists, and are vulnerable to lead and immortal time biases. So we compared time to all-cause mortality among older adults with kidney failure treated vs. not treated with chronic dialysis. Our retrospective cohort study used linked administrative and laboratory data to identify adults aged 65 or more years of age in Alberta, Canada, with kidney failure (2002-2012), defined by two or more consecutive outpatient estimated glomerular filtration rates less than 10 mL/min/1.73m2, spanning 90 or more days. We used marginal structural Cox models to assess the association between receipt of dialysis and all-cause mortality by allowing control for both time-varying and baseline confounders. Overall, 838 patients met inclusion criteria (mean age 79.1; 48.6% male; mean estimated glomerular filtration rate 7.8 mL/min/1.73m2). Dialysis treatment (vs. no dialysis) was associated with a significantly lower risk of death for the first three years of follow-up (hazard ratio 0.59 [95% confidence interval 0.46-0.77]), but not thereafter (1.22 [0.69-2.17]). However, dialysis was associated with a significantly higher risk of hospitalization (1.40 [1.16-1.69]). Thus, among older adults with kidney failure, treatment with dialysis was associated with longer survival up to three years after reaching kidney failure, though with a higher risk of hospital admissions. These findings may assist shared decision-making about treatment of kidney failure.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a progressive loss of kidney function and structure that affects approximately 13% of the population worldwide. A recent meta-analysis revealed that cell-based therapies improve impaired renal function and structure in preclinical models of CKD. We assessed the safety and tolerability of bone marrow-mesenchymal stromal cell (MSC) infusion in patients with CKD. METHODS A single-arm study was carried out at one center with 18-month follow-up in seven eligible patients with CKD due to different etiologies such as hypertension, nephrotic syndrome (NS) and unknown etiology. We administered an intravenous infusion (1-2 × 106 cells/kg) of autologous cultured MSCs. The primary endpoint was safety, which was measured by number and severity of adverse events. The secondary endpoint was decrease in the rate of decrease in estimated glomerular filtration rate (eGFR). We compared kidney function during the follow-up visits to baseline and 18 months prior to the intervention. RESULTS Follow-up visits of all seven patients were completed; however, we have not observed any cell-related adverse events during the trial. Changes in eGFR (P = 0.10) and serum creatinine (P = 0.24) from 18 months before cell infusion to baseline in comparison with baseline to 18 months were not statistically significant. CONCLUSIONS We showed safety and tolerability of a single-dose infusion of autologous MSCs in patients with CKD.

Abstract
BACKGROUND We aimed to investigate the relationship between quality of life and the factors that may influence it in an elderly community-dwelling population in Shanghai. METHODS From August to October 2014, elderly individuals were enrolled from three randomly selected communities in Shanghai. Participant information was collected from responses to a general questionnaire and to the Lubben Social Network Scale-6, Cumulative Illness Rating Scale for Geriatrics, Patient Health Questionnaire, and the 12-item Short Form Health Survey. The factors influencing quality of life were explored in a multivariate stepwise linear regression model. RESULTS Physical and mental component summary scores for the elderly in Shanghai communities were 50.1 ± 10.1 and 47.3 ± 7.9, respectively. Physical component summary scores in the rural area were higher than those in the urban-rural intersection area (a place where urban and rural transitions are taking place) (52.32 ± 9.81 vs 49.63 ± 9.33, P < 0.05) and the urban area (52.32 ± 9.81 vs 47.34 ± 10.18, P < 0.05). Additionally, mental component summary scores in the rural area were higher than those in the urban-rural intersection area (52.63 ± 9.28 vs 48.43 ± 9.42, P < 0.05) and the urban area (52.63 ± 9.28 vs 48.13 ± 10.69, P < 0.05). CONCLUSIONS Depression, self-care ability, and medical care burden were found to be significantly associated with the quality of life of elderly individuals in Shanghai, China. Therefore, more attention should be paid to the mental health of this elderly population.

Abstract
AIMS To estimate the economic burden of kidney disorders in Korea. MATERIALS AND METHODS The economic burden of kidney disorders was estimated using a prevalence-based approach. Related kidney diseases in patients with kidney disorders (RPWKD) were defined using codes from the tenth International Classification of Disease (E70-E90, F30-F48, F60-F69, F90-F99, K65-K67, N00-N08, N17-N19, and N30-N39). All diseases in patients with kidney disorders (APWKD) were defined as kidney disorders that involved all disease codes. Economic costs were divided into direct costs (medical costs and non-medical costs) and indirect costs (productivity loss because of morbidity and premature mortality). RESULTS The prevalence of kidney disorders increased from 0.08% (2008) to 0.11% (2011). The total economic burden of RPWKD also substantially increased from $898.9 million (2008) to $1.43 billion (2011). This ∼59.4% increase in the economic burden was equal to 0.12% of the Korean gross domestic product. The economic burden of APWKD also increased during the study period: $1.06 billion (2008), $1.23 billion (2009), $1.44 billion (2010), and $1.46 billion (2011). CONCLUSIONS The present study provides the first data regarding the economic burden of kidney disorders in Korea. The findings support the need for early intervention services and prevention programs to prevent, identify, and manage kidney disorders.

Abstract
Renal fibrosis represents a final common outcome of many renal diseases and has attracted a great deal of attention. To better understand whether lncRNAs could be a player in this process or be a biomarker for renal fibrosis diagnosis, we compared transcriptome sequencing data on renal tissues and urine respectively between UUO (unilateral ureteral obstruction) and shamed (Sham) rat model. Numerous genes including lncRNAs with significant changes in their expression were identified. 24 lncRNAs were up-regulated and 79 lncRNAs were down-regulated in the renal tissues of the UUO rats. 625 lncRNAs were up-regulated and 177 lncRNAs were down-regulated in urines of the UUO rats. Among the lncRNAs upregulated in renal tissue of UUO rats, 19 lncRNAs were predicted containing several conserved Smad3 binding motifs in the promoter. Among them, lncRNAs with putative promoter containing more than 4 conserved Smad3 binding motifs were demonstrated to be induced by TGF-β significantly in normal rat renal tubular epithelial NRK-52E cells. We further confirmed that lncRNA TCONS_00088786 and TCONS_01496394 were regulated by TGF-β stimulation and also can influence the expression of some fibrosis-related genes through a feedback loop. Based on transcriptome sequencing data, bioinformatics analysis and qRT-PCR detection, we also demonstrated lncRNA in urine are detectable and might be a novel biomarker of renal fibrosis. These results provide new information for the involvement of lncRNAs in renal fibrosis, indicating that they may serve as candidate biomarkers or therapeutic targets in the future.

Abstract
BACKGROUND The chronic kidney disease is a major health concern. The number of the elderly people with chronic renal failure has increased across the world. Dialysis is an appropriate therapy for the elderly, but it involves certain challenges. The present paper reports uncertainty as part of the elderly experiences of living with hemodialysis. METHODS This qualitative study applied Max van Manen interpretative phenomenological analysis to explain and explore experiences of the elderly with hemodialysis. Given the study inclusion criteria, data were collected using in-depth unstructured interviews with nine elderly undergoing hemodialysis, and then analyzed according to Van Manen 6-stage methodological approach. RESULTS One of the most important findings emerging in the main study was "uncertainty", which can be important and noteworthy, given other aspects of the elderly life (loneliness, despair, comorbidity of diseases, disability, and mental and psychosocial problems). Uncertainty about the future is the most psychological concerns of people undergoing hemodialysis. CONCLUSION The results obtained are indicative of the importance of paying attention to a major aspect in the life of the elderly undergoing hemodialysis, uncertainty. A positive outlook can be created in the elderly through education and increased knowledge about the disease, treatment and complications.

Abstract
The incidence of chronic kidney disease (CKD) is increasing, with an estimated prevalence of 12% in the United States (Synder et al., 2009). While CKD may progress to end-stage renal disease (ESRD), which necessitates renal replacement therapy, i.e. dialysis or transplantation, most CKD patients never reach ESRD due to the increased risk of death from cardiovascular disease. It is well-established that regardless of the initiating insult - most often diabetes or hypertension - fibrosis is the common pathogenic pathway that leads to progressive injury and organ dysfunction (Eddy, 2014; Duffield, 2014). As such, there has been extensive research into the molecular and cellular mechanisms of renal fibrosis; however, translation to effective therapeutic strategies has been limited. While a role for the disruption of the cytoskeleton, most notably the actin network, has been established in acute kidney injury over the past two decades, a role in regulating renal fibrosis and CKD is only recently emerging. This review will focus on the role of the cytoskeleton in regulating pro-fibrotic pathways in the kidney, as well as data suggesting that these pathways represent novel therapeutic targets to manage fibrosis and ultimately CKD.
