Using INTERCheck® to Evaluate the Incidence of Adverse Events and Drug–Drug Interactions in Out- and Inpatients Exposed to Polypharmacy

Background: Polypharmacy exposes patients with comorbidities (particularly elderly patients) to an increased risk of drug-specific adverse events and drug–drug interactions. These adverse events could be avoided with the use of a computerized prescription support system in the primary care setting. The INTERCheck® software is a prescription support system developed with the aim of balancing the risks and benefits of polytherapy and examining drug–drug interactions. Objectives: This observational study used the INTERCheck® software to evaluate the incidence of adverse events and of drug–drug interactions in outpatients and inpatients receiving multiple medications. Methods: Patients were randomly enrolled from the outpatient department (n = 98) and internal medicine ward (n = 46) of S. Andrea Hospital of Rome. Polypharmacological treatment was analyzed using INTERCheck® software, and the prevalence of risk indicators and adverse events was compared between the two groups. Results: Polypharmacy (use of five or more drugs) applied to all except three cases among outpatients and one case among inpatients. A significant positive correlation was found between the number of medications and the INTERCheck® score (ρ = 0.67; p < 0.000001), and a significant negative correlation was found between the drug-related anticholinergic burden and cognitive impairment (r = − 0.30 p = 0.01). Based on the INTERCheck® analysis, inpatients had a higher score for class D (contraindicated drug combination should be avoided) than did outpatients (p = 0.01). The potential class D drug–drug interactions were associated with adverse events that caused hospitalization (χ2 = 7.428, p = 0.01). Conclusions: INTERCheck® analysis indicated that inpatients had a high risk of drug–drug interactions and a high percentage of related adverse drug events. Further prospective studies are necessary to evaluate whether the INTERCheck® software may help reduce polypharmacy-related adverse events when used in a primary care setting and thus potentially avoid related hospitalization and severe complications such as physical and cognitive decline

Prevalence of molar incisor hypomineralization among school children in Rome, Italy

Molar incisor hypomineralization (MIH) is a highly prevalent condition associated with increased caries experience, dental pain and treatment need. Aim of this study was to determine the prevalence and severity of MIH in a group of 7–8 years old primary school children living in Rome, Italy; and to assess the association with caries experience and possible perinatal risk factors. A survey has been conducted in the city of Rome, between April 2019 and March 2020 with a total of 49 primary schools and 176 2nd grade primary school classes and a total of 3611 children being involved. Of these, a subset of 346 children of 21 primary schools was selected for the epidemiological investigation. The prevalence of MIH was of 18.2%, with girls showing twice the probability of being subject to a mild-severe condition. Molar location was present in 71.4%, while location on both molar plus incisor was present in 28.6% of cases. The mean DMFT was 0.44 ± 0.78, “D” was 0.17 ± 0.58; the mean dmft was 1.7 ± 2.56, “d” was 1.32 ± 2.21. Female gender, caries experience, insufficient oral hygiene were risk factors. The incidence of MIH is increasing in the pediatric population. Knowledge about diagnosis and treatment options should be disseminated among dental professionals.publishedVersio

Strongly Correlated Quantum Fluids: Ultracold Quantum Gases, Quantum Chromodynamic Plasmas, and Holographic Duality

Strongly correlated quantum fluids are phases of matter that are intrinsically quantum mechanical, and that do not have a simple description in terms of weakly interacting quasi-particles. Two systems that have recently attracted a great deal of interest are the quark-gluon plasma, a plasma of strongly interacting quarks and gluons produced in relativistic heavy ion collisions, and ultracold atomic Fermi gases, very dilute clouds of atomic gases confined in optical or magnetic traps. These systems differ by more than 20 orders of magnitude in temperature, but they were shown to exhibit very similar hydrodynamic flow. In particular, both fluids exhibit a robustly low shear viscosity to entropy density ratio which is characteristic of quantum fluids described by holographic duality, a mapping from strongly correlated quantum field theories to weakly curved higher dimensional classical gravity. This review explores the connection between these fields, and it also serves as an introduction to the Focus Issue of New Journal of Physics on Strongly Correlated Quantum Fluids: from Ultracold Quantum Gases to QCD Plasmas. The presentation is made accessible to the general physics reader and includes discussions of the latest research developments in all three areas.Comment: 138 pages, 25 figures, review associated with New Journal of Physics special issue "Focus on Strongly Correlated Quantum Fluids: from Ultracold Quantum Gases to QCD Plasmas" (http://iopscience.iop.org/1367-2630/focus/Focus%20on%20Strongly%20Correlated%20Quantum%20Fluids%20-%20from%20Ultracold%20Quantum%20Gases%20to%20QCD%20Plasmas

Evaluating and managing severe headache in the emergency department

Introduction: Headache is the fifth most common reason to visit an emergency department (ED). In most of the cases, headache is benign and has a primary origin, with migraine as the most common diagnosis. Inappropriate use of ED for non-emergency conditions causes overcrowding, unnecessary testing, and increased medical costs. Areas covered: All stages of headache management in ED, from the reasons to go there, the diagnosis that is made and the investigations necessary to make it, to get to the therapies administered and those prescribed at discharge, if there were any. Finally, the authors evaluated the habit of recommending medical follow-up and how often the headache is still present at discharge or returns within 24 hours. Expert Opinion: Primary headaches are underdiagnosed, misdiagnosed, and the majority do not receive drug therapy either in ED or on discharge, and in cases where the therapy is prescribed is not specific. Increase the number of primary care medical services, spread the ‘headaches culture’ among GPs and ED doctors, the adoption of ICHD in the diagnostic protocols used in EDs and a fast referral to a headache center could decrease the inappropriate use of ED and improve the headache management in the emergency units

Eptinezumab for the treatment of migraine

Introduction: Migraine is one of the most common illnesses in the world, with severe economical and subjective implications. Nowadays specific and nonspecific drugs are used for migraine chronic therapy, but a portion of patients have no benefit from these administrations. CGRP receptor antagonists are a good preventive treatment for episodic and chronic migraine. Areas covered: This article reviews both preclinical and clinical studies on eptinezumab as a potential preventive therapy for migraine, as well as pharmacokinetic and pharmacodynamic features. Thus, it summarizes safety and tolerability data based on human studies. Expert opinion: Eptinezumab had good results in several trials, making this molecule a promising migraine preventive drug. Although preclinical and clinical studies showed a significant efficacy, there are no data on the use of Eptinezumab during pregnancy or breastfeeding. There are still some knowledge limits about its pharmacokinetics and metabolism. This is a matter of concern that should be addressed in future studies
