[The role of the anesthesiologist in secondary hyperparathyroidism].
2010
In the last years the increasing of diabetes and hypertension has produced a considerable increase of patients with chronic renal failure; secondary hyperparathyroidism is one of the major complications. The resection of hyperfunctioning parathyroid tissue is the ultimate goal of the treatment. The preoperative examination by the anesthetist is the starting-point of the treatment. The anesthetist programs hemodialysis, the correction of fluid and electrolyte abnormalities and of the anaemia. In the operating room the anesthetist is involved in the careful monitoring of liquid infusion and anesthesiological procedure. The intraoperative parathyroid hormone (PTH) assay is an essential tool be…
A randomized multicenter trial on a lung ultrasound-guided treatment strategy in patients on chronic hemodialysis with high cardiovascular risk
2021
Lung congestion is a risk factor for all-cause and cardiovascular mortality in patients on chronic hemodialysis, and its estimation by ultrasound may be useful to guide ultrafiltration and drug therapy in this population. In an international, multi-center randomized controlled trial (NCT02310061) we investigated whether a lung ultrasound-guided treatment strategy improved a composite end point (all-cause death, non-fatal myocardial infarction, decompensated heart failure) vs usual care in patients receiving chronic hemodialysis with high cardiovascular risk. Patient-Reported Outcomes (Depression and the Standard Form 36 Quality of Life Questionnaire, SF36) were assessed as secondary outcome…
Nitric oxide metabolites (nitrite and nitrate) in several clinical condition.
2013
We determined the concentration of nitric oxide metabolites (NO2-+NO3-), expressed as NOx, in several clinical conditions. Regarding this, we have examined 25 subjects with arterial hypertension, 41 subjects with chronic kidney disease in conservative treatment, 106 subjects with metabolic syndrome subdivided according to the presence (n = 43) or not (n = 63) of diabetes mellitus, 48 subjects with obstructive sleep apnea syndrome (OSAS), 14 women with systemic sclerosis complicated with Raynaud's phenomenon, 42 dialyzed subjects and 105 young subjects with acute myocardial infarction (AMI). In subjects with arterial hypertension, chronic kidney disease, metabolic syndrome, systemic sclerosi…
Green Synthesis of Vanillin: Pervaporation and Dialysis for Process Intensification in a Membrane Reactor.
2019
In the present work, two different membrane processes (pervaporation and dialysis) are compared in view of their utilization in a membrane reactor, where vanillin, which is probably the most important aroma of the food industry, is synthesized in a green and sustainable way. The utilized precursor (ferulic acid, which is possibly a natural product from agricultural wastes) is partially oxidized (photocatalytically or biologically) and the product is continuously recovered from the reacting solution by the membrane process to avoid its degradation. It is observed that pervaporation is much more selective towards vanillin than dialysis, but the permeate flux of dialysis is much higher. Furthe…
Cardiorenal syndrome type 4: From chronic kidney disease to cardiovascular impairment
2016
Cardiorenal syndrome type 4 (CRS type 4), or chronic renocardiac syndrome, has been defined as "chronic abnormalities in renal function leading to cardiac disease" and recognizes the extreme burden of cardiovascular disease (CVD) risk in patients with chronic kidney disease (CKD). CKD is common and increasingly recognized as a risk factor for CVD. Even though the treatment for CVD has dramatically improved over the past decades, it still takes responsibility for up to 50% of deaths in CKD patients. For this reason, patients with CKD should be thoroughly evaluated for cardiovascular risk factors that require careful management, given the significant burden of CRS type 4 on the healthcare sys…
SARS-CoV-2 vs. Hepatitis Virus Infection Risk in the Hemodialysis Population: What Should We Expect?
2021
Since the dramatic rise of the coronavirus infection disease 2019 (COVID-19) pandemic, patients receiving dialysis have emerged as especially susceptible to this infection because of their impaired immunologic state, chronic inflammation and the high incidence of comorbidities. Although several strategies have thus been implemented to minimize the risk of transmission and acquisition in this population worldwide, the reported severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence varies across studies but is higher than in the general population. On the contrary, the screening for hepatitis viruses (HBV and HCV) has seen significant improvements in recent years, with va…
Special Considerations for Antihypertensive Agents in Dialysis Patients
2010
Hypertension is present in most patients with end-stage renal disease and likely contributes to the premature cardiovascular disease in dialysis patients. Previous practice guidelines have recommended that, in patients on chronic dialysis, blood pressure (BP) should be reduced below 130/80 mm Hg. This is based on opinions but not strong evidence, since no concrete information exists about which BP values should be the parameter to follow and which should be the target BP values. The majority of the antihypertensive agents can be used in this population, but the pharmacokinetics altered by the impaired kidney function and dialyzability influence the appropriate dosage as well as the time and…
Enhanced prediction of hemoglobin concentration in a very large cohort of hemodialysis patients by means of deep recurrent neural networks.
2019
Erythropoiesis Stimulating Agents (ESAs) have become a standard anemia management tool for End Stage Renal Disease (ESRD) patients. However, dose optimization constitutes an extremely challenging task due to huge inter and intra-patient variability in the responses to ESA administration. Current data-based approaches to anemia control focus on learning accurate hemoglobin prediction models, which can be later utilized for testing competing treatment choices and choosing the optimal one. These methods, despite being proven effective in practice, present several shortcomings which this paper intends to tackle. Namely, they are limited to a small cohort of patients and, even then, they fail to…

Association between oral findings and laboratory tests in children and adolescents undergoing dialysis: A cross- sectional study
2017
Background Diagnosis of oral complications in the dialysis patients is important to prevent potential infections. The aim of this cross-sectional study was to compare oral findings in dialysis patients with healthy individuals and determination of the correlation of these findings and laboratory tests. Material and methods In this cross-sectional study, DMFT, dmft, DI , CI , OHIS , PI, GI and enamel defects were evaluated in 25 hemodialysis patients, 30 peritoneal dialysis patients and 26 healthy individuals. Then the correlation of laboratory tests (including Hemoglobin, Urea, Creatinine, Ca, Na, Ph, K and ALP) and oral findings was determined in each groups using SPSS (Version 16). Data a…
