CONCLUSIONS In middle-aged and elderly individuals without CKD, arterial stiffness determined by obesity, dyslipidemia and increased pulse pressure, was significantly associated with increased serum levels of cystatin C. PMID: 31793519 [PubMed - in process]

Objectives: To assess the particularities of patients with obstructive sleep apnea syndrome (OSAS) and heart failure (HF) focusing in the latest guideline recommendation of mid-range ejection fraction (HFmrEF) and comparing with reduced EF (HFrEF) and preserved EF (HFpEF).Methods: A number of 143 older patients with OSAS and HF were evaluated in 3 sleep labs of Victor Babes Hospital and Cardiovascular Institute, Timisoara, Western Romania. We collected general data, sleep questionnaires, anthropometric, comorbidities, lab test results and performed polysomnography and echocardiographic measurements.Results: Patients were d...

Background: Altered sleep quality has been reported in chronic kidney disease (CKD). However, most studies focused on dialyzed patients or were based on subjective reports that did not consider possible coexistence of obstructive sleep apnea (OSA).Aim: To evaluate, with a case-control design, if objective sleep quality differs between patients with stage 3 CKD and subjects with normal estimated glomerular filtration rate (eGFR) independent of sleep disordered breathing.Methods: In the European Sleep Apnea Database (ESADA) cohort, 527 patients who had undergone full polysomnography and had an eGFR60.Results: CKD patients we...

Background: Sleep disordered breathing (SDB) is prevalent in patients with chronic kidney disease (CKD) in particular those with end-stage renal disease (ESRD). Fluid overload plays a key role in the pathogenesis of obstructive and central sleep apnea (OSA and CSA) in ESRD. We hypothesized that in patients with ESRD, removal of water or uremic substances by hemodialysis would reduce SDB.Methods: We conducted sleep studies for 7 consecutive days using the SD-101 (Kentzmedico Co. Ltd, Saitama, Japan), which is a novel, non-restrictive, a sheet-type device of SA screening for 9 ESRD patients undergoing maintenance hemodialysi...

Heart failure with preserved ejection fraction (HFpEF) is an increasingly studied entity accounting for 50% of all diagnosed heart failure and that has claimed its own dignity being markedly different from heart failure with reduced EF in terms of etiology and natural history (Graziani et al., 2018). Recently, a growing body of evidence points the finger toward microvascular dysfunction as the major determinant of the pathological cascade that justifies clinical manifestations (Crea et al., 2017). The high burden of comorbidities such as metabolic syndrome, hypertension, atrial fibrillation, chronic kidney disease, obstruc...

sti R Abstract Protein carbonylation is a marker of oxidative protein damage, that is likely involved in the pathogenesis of several diseases. The aim of this study was to evaluate the protein carbonyl (PC) groups in different clinical conditions. It included different groups of subjects: 81 trained subjects; 23 subjects with mild essential hypertension; 31 middle-aged subjects with metabolic syndrome (MS); 106 subjects with MS not selected for age (subdivided into two subgroups, with and without diabetes mellitus); 91 obese adults subdivided in two subgroups (BMI 30-35 Kg/m2 and BMI > 35 kg/m2); 48 subject...

The objectives of this study were to explore associations between OSA severity using the apnea-hypopnea-index(AHI) and obstructive apnea-hypopnea-index(OAHI) on polysomnography (PSG), OSA symptoms, and measures of hypertension in children with CKD.MethodsOne-night in-laboratory PSGs and 24-h ambulatory blood pressure monitoring (ABPM) were performed on children with CKD stages 2 –5 (non-dialysis dependent). Sleep questionnaires, including the modified Epworth Sleepiness Scale (ESS) and the Pediatric Sleep Questionnaire (PSQ), were administered during the sleep study.ResultsNineteen children and adolescents completed ...

ConclusionsOSCS is a rare disorder. Diagnosis can often be challenging because other diseases, such as osteopetrosis, pyknodysostosis, Paget disease of bone, and other sclerosing bone dysplasias, make this difficult to diagnose. Radiologists should be aware of the specific radiographic appearance of this condition to aid in the proper diagnosis and management of these patients.

The objective of this review is to describe the epidemiology of sleep apnea in chronic kidney disease, understand the pathophysiological mechanisms by which obstructive sleep apnea can lead to progression of chronic kidney disease, and consider the role of treatment with continuous positive airways pressure in this regard. The review also explores the pathophysiological mechanism by which end stage renal disease can lead to sleep apnea and considers how intensification of renal replacement therapy or extra fluid removal by ultrafiltration may attenuate the degree of sleep apnea severity in this population.
