The diabetic ketoacidosis

2014

The Diabetic Ketoacidosis (DKA) is still today a medical emergency in pediatrics. Despite the latest great sensibilization of the population and the doctors, the risk of DKA has not yet been eliminated and this pathology is still occurring in 25 to 40% of diabetes onset cases, in already diagnosed patients with poor compliance (10%), in patients undergoing acute medical or surgical events or in patients in Continuous Subcoutaneous Insulin Therapy (CSII). In toddlers (0-3 years) it is twice more frequent than in the following ages and is characterized by the presence of more serious clinical dehydratation (>10%) and neurological signs (obnubilation 40%). The other category at risk is represe…

Anthropometric measurements of the body composition of cancer patients determine the precise role of the body surface area and the calculation of the…

2012

The calculation of an accurate dose of chemotherapy for oncological patients reduces the possible medication errors and the toxicity of the body and so it improves the outcome of the treatment (survival). In oncological practice for the calculation of the dose of chemotherapy the human body surface area (BSA) is used. The human body surface area is determined by derived formulas, but it is not directly linked to the pharmacokinetics of the drugs. Pharmacokinetic studies have demonstrated that for the calculation of the chemotherapy dose the actual body weight should be taken into account rather than the ideal one. In the therapeutic dose determination the body fat mass has essential signifi…

SAT0656 DAPSA OR MDA/VLDA CRITERIA FOR DEFINING THE TREATMENT TARGET IN PSORIATIC ARTHRITIS? CROSS-SECTIONAL ANALYSIS FROM A MULTICENTER ITALIAN COHO…

2019

Background: According to international recommendations, psoriatic arthritis (PsA) should be managed by a treat-to-target approach, but the identification of the best tool for defining the target of remission/low disease activity (LDA) is still controversial. Objectives: To evaluate and compare the rates of remission/LDA by comparing Disease Activity in PSoriatic Arthritis (DAPSA) score with Very Low Disease Activity (VLDA)/Minimal Disease Activity (MDA) criteria in a real-life multicentre cohort of PsA patients. Methods: We performed a cross-sectional analysis including the first consecutive 500 PsA patients evaluated in 8 Italian rheumatology centres since September 2017. The rates of pati…

Short- and long-term outcomes for the surgical treatment of acute pulmonary embolism

2018

AbstractObjectivesAcute pulmonary embolism can be a life-threatening condition with a high mortality. The treatment choice is a matter of debate. The early and late outcomes of patients treated with surgical pulmonary embolectomy for acute pulmonary embolism in a single center were analyzed.MethodsAll consecutive patients operated on for pulmonary embolism between January 2002 and March 2017 were reviewed. Patient demographics and pre- and postoperative clinical data were retrieved from our patient registry, and risk factors for in-hospital and long-term mortality were identified.ResultsIn total, 175 patients (mean age 59±3 years, 50% male) were operated on for acute pulmonary embolism. In-…

Genistein supplementation and cardiac function in postmenopausal women with metabolic syndrome: Results from a pilot strain-echo study

2017

Genistein, a soy-derived isoflavone, may improve cardiovascular risk profile in postmenopausal women with metabolic syndrome (MetS), but few literature data on its cardiac effects in humans are available. The aim of this sub-study of a randomized double-blind case-control study was to analyze the effect on cardiac function of one-year genistein dietary supplementation in 22 post-menopausal patients with MetS. Participants received 54 mg/day of genistein (n = 11) or placebo (n = 11) in combination with a Mediterranean-style diet and regular exercise. Left ventricular (LV) systolic function was assessed as the primary endpoint, according to conventional and strain-echocardiography measurement…

Importance of the liquid to solid weight ratio in the powdered solid-liquid reactions Example drawn from cement constituent hydration

1997

Abstract It seems justified to wonder if the chemical processes which have been evidenced from diluted stirred suspensions are or are not in accordance with those involved in a stagnant paste. The present paper is aimed at clarifying this question which is in connection with the problem of the so called ‘dormant period’ or ‘induction period’ at the beginning of the hydration of Portland cement.

Effect of superplasticizers on the rheological properties of fly ash suspensions containing activators of the pozzolanic reaction

2000

Rheological studies have been carried out on the effect of a superplasticizer from the sulphonated melamine formaldehyde (SMF) group upon the properties of fly ash suspensions containing a small quantity of mineral admixtures such as cement, lime and gypsum. The superplasticizers' efficiency has appeared to depend greatly on the admixture used. The highest liquefaction degree was found in fly ash suspensions containing both cement and gypsum together and the next it was, when only cement was added. These suspensions exhibit features of a newtonian fluid of low plastic viscosity, when the water to solid ratio (w/s) is 0.3 and a superplasticizer has been used. However, fly ash suspensions wit…

Physicochemical parameters - hydration performance relationship of the new endodontic cement MTA Repair HP

2019

Background To characterize the chemical composition and textural parameters of the MTA Repair HP precursor powder and their influence to hydration performance. Material and methods Un-hydrated precursor material was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray fluorescence (XRF), laser diffraction (LD), N2 physisorption and field emission gun scanning electron microscopy (FEG-SEM). Setting time was assessed according to ASTM specification C 266. Hydrated material was analysed by XRD, FT-IR, energy dispersive X-ray (EDX) analysis and FEG-SEM. Results Ca3SiO5 and Ca2SiO4, in addition to CaWO4 as radiopacifier are the main compositional phase…
