Equilibrium Studies in Natural Fluids. A Chemical Speciation Model for the Major Constituents of Seawater.
1994
AbstractThe speciation of CI−, OH− and SO42- in synthetic sea water has been studied by Potentiometric measurements (pH-metric and ISE-Na methods) and by literature data analysis, using a well tested complex formation model. Stability constants, together with distribution of hypothesised species in synthetic sea water, as a function of temperature and salinity, are reported. The speciation model proposed in this work is discussed on the basis of chemical and statistical considerations. Comparison with some literature sea water models is given.
Do Degree Programs Affect Health Profession Students' Attitudes and Opinions Toward Vaccinations? An Italian Multicenter Study
2019
Abstract Background Healthcare workers' attitudes toward vaccination have been widely described in the literature, but a restricted amount of studies assessed healthcare students' knowledge, attitudes, and opinions on this issue. This study aimed to estimate the influence of a degree course on knowledge and immunization behavior among healthcare students and to compare medical students with students from other health profession degree programs to identify possible differences. Methods A multicenter, cross-sectional study was performed in 2018 in 14 Italian Universities (3,131 students were interviewed). A validated questionnaire was used to assess knowledge, attitudes, and opinions toward v…
Therapeutical approach to plasma homocysteine and cardiovascular risk reduction
2008
Marcello Ciaccio, Giulia Bivona, Chiara BelliaDepartment of Medical Biotechnologies and Forensic Medicine, Faculty of Medicine, University of Palermo, ItalyAbstract: Homocysteine is a sulfur-containing aminoacid produced during metabolism of methionine. Since 1969 the relationship between altered homocysteine metabolism and both coronary and peripheral atherotrombosis is known; in recent years experimental evidences have shown that elevated plasma levels of homocysteine are associated with an increased risk of atherosclerosis and cardiovascular ischemic events. Several mechanisms by which elevated homocysteine impairs vascular function have been proposed, including impairment of endothelial…
Xerostomia induced by radiotherapy: an overview of the physiopathology, clinical evidence, and management of the oral damage
2015
Background: The irradiation of head and neck cancer (HNC) often causes damage to the salivary glands. The resulting salivary gland hypofunction and xerostomia seriously reduce the patient’s quality of life. Purpose: To analyze the literature of actual management strategies for radiation-induced hypofunction and xerostomia in HNC patients. Methods: MEDLINE/PubMed and the Cochrane Library databases were electronically evaluated for articles published from January 1, 1970, to June 30, 2013. Two reviewers independently screened and included papers according to the predefined selection criteria. Results: Sixty-one articles met the inclusion criteria. The systematic review of the literature sugge…
A low threshold to ECG-gated repeat CTA reduces the risk of false-positive diagnosis of type A dissection in interhospital referrals: a case series s…

Given that electrocardiography (ECG)-gated CTA provides greater diagnostic safety, it may be assumed that interhospital referral…
Beclomethasone/formoterol fixed combination for the management of asthma: patient considerations.
2008
Gabriele Nicolini1, Nicola Scichilone2, Andrea Bizzi3, Alberto Papi4, Leonardo M Fabbri51Medical Department, Chiesi Farmaceutici, Parma, Italy; 2University of Palermo, DIMPEFINU, Palermo, Italy; 3Department of Scientific Affairs, Chiesi Farmaceutici, Parma, Italy; 4Research Center on Asthma and COPD, University of Ferrara, Ferrara, Italy; 5Section of Respiratory Diseases, University of Modena, Modena, ItalyAbstract: Drugs for asthma and other chronic obstructive diseases of the lungs should be preferably delivered by the inhalation route to match therapeutic effects with low systemic exposure. Inhaled drugs are delivered to the lungs via different devices, mainly metered dose inhalers and d…
<p>Future perspectives of anticholinergics for the treatment of asthma in adults and children</p>
2019
Despite major advances in therapeutic interventions and the availability of detailed treatment guidelines, a high proportion of patients with symptomatic asthma remain uncontrolled. Asthma management is largely guided by the Global Initiative for Asthma (GINA) strategy and is based on a backbone of inhaled corticosteroid (ICS) therapy with the use of additional therapies to achieve disease control. Inhaled long-acting bronchodilators alone and in combination are the preferred add-on treatment options. Although long-acting muscarinic antagonists (LAMAs) are a relatively recent addition to disease management recommendations for asthma, tiotropium has been extensively studied in a large clinic…
Intrauterine and Neonatal Exposure to Opioids: Toxicological, Clinical, and Medico-Legal Issues
2023
Opioids have a rapid transplacental passage (i.e., less than 60 min); furthermore, symptoms characterize the maternal and fetal withdrawal syndrome. Opioid withdrawal significantly impacts the fetus, inducing worse outcomes and a risk of mortality. Moreover, neonatal abstinence syndrome (NAS) follows the delivery, lasts up to 10 weeks, and requires intensive management. Therefore, the prevention and adequate management of NAS are relevant public health issues. This review aims to summarize the most updated evidence in the literature regarding toxicological, clinical, and forensic issues of intrauterine exposure to opioids to provide a multidisciplinary, evidence-based approach for managing …
Organisational climate and employee health outcomes: a systematic review
2019
Organisational climate, particularly safety climate, has been documented as a crucial element in promoting occupational health and safety. However, most previous studies have focused more on safety issues (e.g., injuries and accidents) rather than health outcomes (e.g., illnesses, stress, etc). A comprehensive review is also lacking in relation to understanding the organisational climate–health relationship between different levels of analysis, different data sources and different analytical procedures. We conducted a systematic review to investigate previous scholarly contributions to organisational climate and health. The reviewed articles were obtained from three databases: ISI Web of Kn…
Speciation of dimethyltin(IV) – and trimethyltin(IV) – carbocysteinate and – glutamate systems in aqueous media
2008
The formation of complex species in the dimethyltin(IV) and trimethyltin(IV)-carboxymethyl-L-cysteinate (carbocysteinate) systems in NaClaq, at different ionic strengths, and in a multicomponent Na+, K+, Ca2+, Mg2+, Cl- and SO42- medium representative of the seawater major composition, is discussed. Experimental results give evidence for the formation of the following species (L¼carbocysteinate): [(CH3)2Sn(L)]0, [(CH3)2Sn(HL)]+, [(CH3)2Sn(OH)(L)]-, [(CH3)2Sn(OH)2(L)]2- in the DMT–CCYS system, and [(CH3)3Sn(HL)]0, [(CH3)3Sn(L)]- and [(CH3)3Sn(OH)(L)]2- in the TMT-CCYS system. The ionic strength dependence of formation constants was taken into account by an extended Debye Huckel type equation…
