Polymorphonuclear leukocyte integrins in chronic renal failure
2005
Patients with chronic renal failure (CRF), in comparison with general population, show a higher cardiovascular mortality, not fully explained by the "traditional" risk factors. Among the new factors that have been hypothesized, leukocytes might play an important role. In a group of patients with mild CRF we determined, at baseline and after in vitro activation with 4-phorbol-12-myristate-13-acetate (PMA) and N-formyl-methionyl-leucyl-phenylalanine (fMLP), the polymorphonuclear leukocytes (PMN) beta2-integrin pattern (CD11a, CD11b, CD11c and CD18) by using indirect immunofluorescence with a flow cytometer. At baseline we observed an increase in the phenotypical expression of CD11b, CD11c and…
Gitelman-Like Syndrome Caused by Pathogenic Variants in mtDNA
2022
Contains fulltext : 248375.pdf (Publisher’s version ) (Closed access) BACKGROUND: Gitelman syndrome is the most frequent hereditary salt-losing tubulopathy characterized by hypokalemic alkalosis and hypomagnesemia. Gitelman syndrome is caused by biallelic pathogenic variants in SLC12A3, encoding the Na(+)-Cl(-) cotransporter (NCC) expressed in the distal convoluted tubule. Pathogenic variants of CLCNKB, HNF1B, FXYD2, or KCNJ10 may result in the same renal phenotype of Gitelman syndrome, as they can lead to reduced NCC activity. For approximately 10 percent of patients with a Gitelman syndrome phenotype, the genotype is unknown. METHODS: We identified mitochondrial DNA (mtDNA) variants in th…
Impact of rectal distension on prostate CBCT-based positioning assessed with 6 degrees-of-freedom couch
2018
International audience; Introduction: Prostate requires a daily correction of its 3-dimensional position in relation with rectal distension. In this study, we sought to determine whether rectal distension with respect to the rectal behavior might have an impact on prostate translations and/or rotations during prostate image guided radiation therapy using a 6 degrees-of-freedom (DOF) couch.Methods and materials: We reviewed the data from 39 patients with localized prostate cancer treated with protracted external radiation therapy using a 6 DOF couch. Before each fraction, a kilovoltage cone beam computed tomography (kV-CBCT) scan was performed. The automatic fusion algorithm was set to fuse …
Encapsulating peritoneal sclerosis: do not be too late for the right diagnosis! Case report and short literature review
2020
Encapsulating peritoneal sclerosis (EPS) is a rare clinical syndrome characterized by an acquired, inflammatory fibrocollagenous membrane encasing the small intestine, resulting in symptoms of bowel obstruction. It is still unclear whether early surgical intervention has an advantage over conservative management, but, in most reviewed case reports, it is preferred to preserve the surgical management in patients not responding to conservative measures, or when bowel ischaemia is occurring. We report a case of a 58-year old patients, affected by chronic renal failure, on treatment with peritoneal dialysis, in which a late diagnosis of encapsulating peritoneal sclerosis was made, and where sur…
Patient Alert to detect ICD lead failure: efficacy, limitations, and implications for future algorithms.
2006
Aims An algorithm that alerts implantable cardioverter-defibrillator (ICD) patients, in case of abnormal lead impedance (Patient Alert™, Medtronic), may help to recognize lead dysfunction. We aimed to determine the utility of Patient Alert for ICD lead-failure detection in a prospective study. Methods and results Three hundred and sixty ICD patients were followed for 22±14 months. Patient Alert was active for pacing impedance 2000–3000 Ω, and high-voltage conductor impedance 200 Ω. Ten alert events and a total of 29 severe system complications occurred. Patient Alert detected three of 10 ICD lead failures, with a positive predictive value (PPV) of 77.8% for any severe system complication. R…
Prognostic Value of Initial Left Ventricular Remodeling in Patients With Reperfused STEMI
2019
Abstract Objectives This study sought to establish the best definition of left ventricular adverse remodeling (LVAR) to predict outcomes and determine whether its assessment adds prognostic information to that obtained by early cardiac magnetic resonance (CMR). Background LVAR, usually defined as an increase in left ventricular end-diastolic volume (LVEDV) is the main cause of heart failure after an ST-segment elevated myocardial infarction; however, the role of assessment of LVAR in predicting cardiovascular events remains controversial. Methods Patients with ST-segment elevated myocardial infarction who received percutaneous coronary intervention within 6 h of symptom onset were included …

Low Rate of Virological Failure and Maintenance of Susceptibility to HIV-1 Protease Inhibitors with First-Line Lopinavir/Ritonavir-Based Antiretrovir…
2010
Protease inhibitor (PI)-resistant HIV-1 has hardly ever been detected at failed boosted PI-based first-line antiretroviral regimens in clinical trials. However, this phenomenon has not been investigated in clinical practice. To address this gap, data from patients starting a first-line lopinavir/ritonavir (LPV/rtv)-based therapy with available baseline HIV-1 RNA load, a viral genotype and follow-up viral load after 3 and 6 months of treatment were extracted from the Italian Antiretroviral Resistance Cohort Analysis (ARCA) observational database. Based on survival analysis, 39 (7.1%) and 43 (7.8%) of the 548 examined patient cases had an HIV-1 RNA >500 and >50 copies/ml, respectively, after …
Observed and relative survival and 5-year outcomes of patients discharged after acute myocardial infarction: the nationwide AMI-PL database.
2020
Background: Long‑term follow‑up data from a large Polish acute myocardial infarction (AMI‑PL) database are still unavailable. Aims: This study aimed to assess the 5‑year outcomes of patients discharged after hospitalization for AMI in Poland in relation to age. Methods: The studywas based on the nationwide AMI‑PL registry including data on the management and long‑term outcomes of all patients admitted to hospitals with AMI (codes I21–I22 according to the International Classification of Diseases and Related Health Problems, 10th Revision [ICD ‑10]), derived from the database of the obligatory healthcare payer in Poland.The current analysis included all patients after AMI who were discharged …
Effects of an eccentric training personalized by a low rate of perceived exertion on the maximal capacities in chronic heart failure: a randomized co…
2016
International audience; BACKGROUND: The eccentric (ECC) training, in spite of its potential interest (slightest request of the cardiorespiratory system) compared with the concentric (CON) training, is not applied during the rehabilitation of the chronic heart failure (CHF). The main reasons are the difficulty personalizing the ECC exercises by avoiding the muscle complications and the lack of information concerning the specific effects on the maximal capacities in CHF patients.AIM: To compare — following a prior study on the feasibility and on the functional impacts — the effects on maximal capacities and tolerance in CHF of ECC training tailored by a low rate of perceived exertion (RPE) an…
