Prevalence of biliary lithiasis in a Sicilian population of chronic renal failure patients.
2003
BACKGROUND The aim of this study was to evaluate the prevalence of biliary lithiasis (BL) and associated risk factors in a population of undialysed patients with chronic renal failure (CRF), and to compare these with findings we had obtained previously in chronic haemodialysis (HD) patients and in subjects from the general population located in the same geographic region. METHODS A total of 118 CRF patients on conservative treatment were included in the study. In all subjects, we measured several clinical and humoral parameters potentially correlated with BL. Liver and biliary tract ultrasonography was performed with a 3.5 MHz linear probe after at least 12 h of fasting. RESULTS The prevale…
A reinforcement learning approach for individualizing erythropoietin dosages in hemodialysis patients
2009
This paper presents a reinforcement learning (RL) approach for anemia management in patients undergoing chronic renal failure. Erythropoietin (EPO) is the treatment of choice for this kind of anemia but it is an expensive drug and with some dangerous side-effects that should be considered especially for patients who do not respond to the treatment. Therefore, an individualized treatment appears to be necessary. RL is a suitable approach to tackle this problem. Moreover, resulting policies are similar to medical protocols, and hence, they can easily be transferred to daily practice. A cohort of 64 patients are included in the study. An implementation of the Q-learning algorithm based on a st…
Inflammation is an amplifier of lung congestion by high lv filling pressure in hemodialysis patients: a longitudinal study
2019
Introduction Since infammation alters vascular permeability, including vascular permeability in the lung, we hypothesized that it can be an amplifer of lung congestion in a category of patients at high risk for pulmonary oedema like end stage kidney disease (ESKD) patients. Objective and methods We investigated the efect modifcation by systemic infammation (serum CRP) on the relationship between a surrogate of the flling pressure of the LV [left atrial volume indexed to the body surface area (LAVI)] and lung water in a series of 220 ESKD patients. Lung water was quantifed by the number of ultrasound B lines (US-B) on lung US. Six-hundred and three recordings were performed during a 2-year f…

Perifērās neiropātijas izmeklēšana hemodialīzes pacientiem
2018
Pamatinformācija: Hroniska nieru slimība (HNS) ir globāla veselības problēma, kuras vidējā izplatība Eiropā ir 18.4 %. Perifērā neiropātija (PN) ir visizplatītākā neiroloģiskā komplikācija (~ 60 līdz 100 %) šiem pacientiem. PN diagnoze ietver padziļinātu klīnisko izmeklēšanu, tai skaitā pacienta slimības vēstures analīzi, neiroloģisko izmeklēšanu, laboratorisko testēšanu un elektrofizioloģiskās izmeklēšanas metodes. Skrīninga metodes var palīdzēt agrīni noteikt PN HNS pacientiem un laicīgi sākt terapiju, mainot slimības attīstības gaitu. Mērķis: Noteikt perifēro neiropātiju HNS pacientiem ar Mičiganas neiropātijas skrīninga metodes (MNSI) palīdzību, kas apstiprināta un pielietota cukura dia…
Sleep Apnea and the Kidney
2020
Abstract Purpose of Review There are some uncertainties about the interactions between obstructive sleep apnea (OSA) and chronic kidney disease (CKD). We critically reviewed recent studies on this topic with a focus on experimental and clinical evidence of bidirectional influences between OSA and CKD, as well as the effects of treatment of either disease. Recent Findings Experimental intermittent hypoxia endangers the kidneys, possibly through activation of inflammatory pathways and increased blood pressure. In humans, severe OSA can independently decrease kidney function. Treatment of OSA by CPAP tends to blunt kidney function decline over time, although its effect may vary. OSA may increa…
Self-Organising Maps: A new way to screen the level of satisfaction of dialysis patients
2012
Highlights? FME as dialysis services global provider monitors patient satisfaction in its network. ? A specific questionnaire was developed and administered to the hemodialysis patients. ? To detect residual area of low satisfaction the Self-Organising Map was implemented. ? This method allows identifying niches of dissatisfaction for specific patient groups. Evaluation of patient satisfaction has become an important indicator for assessing health care quality. Fresenius Medical Care (FME) as a global provider of dialysis services through its NephroCare network has a strong interest in monitoring patient satisfaction.The aim of the paper is to test and validate a methodology for detecting a…
Evaluation of changes in salivary composition in renal failure patients before and after hemodialysis
2017
Background Saliva plays a major role in preserving the integrity of oral tissues. The oral health of renal failure patients could be negatively affected by the underlying pathology, the dialysis treatment, or an altered salivary composition. Major systemic changes occur during hemodialysis (HD), which could affect the flow rate and biochemical composition of saliva. Therefore, the aim of this study was to evaluate the effects of HD on the salivary flow rate, pH and biochemical composition before and after completion of a dialysis session. Material and methods Thirty Renal failure patients undergoing hemodialysis were selected based on the inclusion and exclusion criteria set forth for the s…
Evaluation of salivary parameters and dental status in adult hemodialysis patients in an indian population.
2018
Background Renal failure is a process that expresses a loss of functional capacity of the nephrons, independently of its etiology. The most widely used technique to combat renal failure is hemodialysis. Renal failure causes various systemic alterations including oral complications such as variations in the flow and composition of the saliva. Caries is a multifactorial disease and impaired stimulated salivary flow rate and buffering capacity are the best-known risk factors. The present study aims to evaluate the salivary pH, buffering capacity and the flow rate of saliva to the DMFT status in adult hemodialysis patients among the Indian population. Material and Methods Twenty healthy individ…
