Far-Field Pattern Reconstruction from Near-Field Data Collected via a Nonconventional Plane-Rectangular Scanning: Experimental Testing

This paper deals with the experimental validation of an efficient near-field-far-field (NF-FF) transformation using the planar wide-mesh scanning (PWMS). Such a nonconventional plane-rectangular scanning technique is so named, since the sample grid is characterized by meshes wider and wider when going away from the center, and makes it possible to lower the number of needed measurements, as well as the time required for the data acquisition when dealing with quasi-planar antennas. It relies on the use of the nonredundant sampling representations of electromagnetic fields which employ an oblate ellipsoid or a surface formed by two circular "bowls" with the same aperture diameter but eventually different bending radii to shape a quasi-planar antenna. A two-dimensional optimal sampling interpolation formula allows the reconstruction of the NF data at any point on the measurement plane and, in particular, at those required by the classical NF-FF transformation with the conventional plane-rectangular scanning. The measurements, performed at the planar NF facility of the antenna characterization laboratories of Selex ES, have confirmed the effectiveness of this innovative scanning also from the experimental viewpoint

The Yin and Yang of Current Antifungal Therapeutic Strategies: How Can We Harness Our Natural Defenses?

Fungal infections have aroused much interest over the last years because of their involvement in several human diseases. Immunocompromission due to transplant-related therapies and malignant cancer treatments are risk factors for invasive fungal infections, but also aggressive surgery, broad-spectrum antibiotics and prosthetic devices are frequently associated with infectious diseases. Current therapy is based on the administration of antifungal drugs, but the occurrence of resistant strains to the most common molecules has become a serious health-care problem. New antifungal agents are urgently needed and it is essential to identify fungal molecular targets that could offer alternatives for development of treatments. The fungal cell wall and plasma membrane are the most important structures that offer putative new targets which can be modulated in order to fight microbial infections. The development of monoclonal antibodies against new targets is a valid therapeutic strategy, both to solve resistance problems and to support the immune response, especially in immunocompromised hosts. In this review, we summarize currently used antifungal agents and propose novel therapeutic approaches, including new fungal molecular targets to be considered for drug development

PharmaCare 2018

[Italiano]: Il farmaco, nella sua accezione più ampia e generale, può essere ritenuto un bene sociale, la cui valenza simbolica e curativa varia in relazione alla dimensione ambientale e culturale nel quale si inserisce. In tal senso, le prescrizioni farmaceutiche rappresentano un indicatore privilegiato per la conoscenza del sistema salute di un determinato territorio, poiché costituiscono un punto di intersezione ideale tra la prospettiva medica e quella di mercato. Siffatte considerazioni hanno sollecitato l’elaborazione di questo Report che si pone, come obiettivi dichiarati, quello di essere uno strumento utile alla pianificazione di interventi di sanità pubblica, quanto quello di svolgere analisi approfondite sulle caratteristiche dei soggetti che usano i farmaci e sulle modalità di trattamento degli stessi, permettendo studi di appropriatezza prescrittiva su specifiche aree di rilevanza clinica e su specifiche coorti di soggetti. “PharmaCaRe Report 2018” è stato realizzato dal CIRFF (Centro Interdipartimentale di Ricerca in Farmacoeconomia e Farmacoutilizzazione) dell’Università degli Studi di Napoli Federico II, in collaborazione con la Direzione Generale della Tutela della Salute della Regione Campania, per delineare un quadro dettagliato circa il consumo e la prescrizione dei farmaci in Campania nel 2018. Questo Report intende infatti fornire una fotografia dettagliata dell’utilizzo che, in Campania, viene fatto dei farmaci in termini di spesa, volumi e tipologia. Le analisi dei dati prodotte offrono spunti importanti per correlare la prevalenza delle patologie nel territorio con il corrispondente utilizzo dei farmaci e suggeriscono un’interpretazione dei principali fattori che influenzano la variabilità nella prescrizione. La disponibilità di una banca dati che copre una popolazione assistibile di circa sei milioni di abitanti è d’altronde un potente strumento di ricerca per studiare gli effetti dell’utilizzo dei farmaci in condizioni di Real-World. La conoscenza delle dinamiche prescrittive, in termini qualitativi (appropriatezza d’uso), oltre che quantitativi (volumi di utilizzo) è la condizione necessaria per inquadrare in un contesto razionale la politica del farmaco, anche sotto il profilo della valutazione degli effetti degli interventi che il mercato, le normative o la cultura del farmaco sviluppano nel tempo. Per tali ragioni, “PharmaCaRe Report 2018” rappresenta un utile quanto prezioso supporto ai decisori per individuare strategie volte a ottimizzare l’allocazione delle risorse, nonché migliorare i percorsi di cura attraverso un monitoraggio costante, la promozione di più elevati standard di cura e l’uso sicuro, efficiente ed efficace dei farmaci ./[English]: In its broadest and most general sense, the drug can be considered a public resource, whose symbolic and curative value varies in relation to the environmental and cultural dimension in which it is embedded. In this sense, pharmaceutical prescriptions represent a privileged indicator for the knowledge of the health system of a given territory, since they constitute an ideal intersection point between the medical and the market perspective. Such considerations prompted the preparation of this Report. “PharmaCaRe Report 2018” has been produced by CIRFF (Centro Interdipartimentale di Ricerca in Farmacoeconomia e Farmacoutilizzazione) of the Federico II University of Naples, in collaboration with the Directorate-General for Health Protection of the Campania Region, to provide a detailed overview of the pharmaceutical consumption and prescriptions in Campania in 2018. This Report aims to provide a detailed picture of the use of medicines in the general population in Campania, in terms of expenditure, volumes and type. The analyses of the data produced offer important clues for correlating the prevalence of diseases in this area with the respective use of medicines and suggest an interpretation of the main factors influencing prescriptions' variability. The availability of a database covering a patient population of around six million is a powerful research tool for studying the effects of drug use in Real-World conditions. Knowledge of the dynamics of prescription, in qualitative terms (appropriateness of use), as well as quantitative (volumes of use) is the necessary condition to frame the drug policy in a rational context, also in terms of evaluating the effects of the interventions that the market, regulations or drug culture develop over time. For these reasons, “PharmaCaRe Report 2018” represents a useful and valuable tool for political decision-makers in identifying strategies aimed at optimizing the allocation of resources, as well as improving care pathways through constant monitoring, the promotion of higher standards of care and safe, efficient and effective use of drugs

Investigations into mechanisms modulating proliferation, differentiation, and apoptosis in cultured liver, adrenal, skin, and bone cells

The intricate modulatory roles played by manifold hormones, growth factors, cytokines, extracellular calcium concentrations, intracellular second messengers, protein kinases, and nuclear poly(ADP-ribose) polymerase in proliferative, differentiative, and apoptotic processes have been the subject of investigations that were carried out by means of in vitro either primary or secondary/tertiary cultures of differentiated epithelial (hepatocytes, keratinocytes, and adrenocytes) and connective tissue cells (osteoblasts and fibroblasts) obtained from man and/or other mammalians. In most cases, an ad hoc model system, in which cells were floated on the top of the growth medium and, hence, could enjoy nearly normal respiratory exchanges, was used. Such a system increased cell viability and the ability of parenchymal epithelial cells to respond to extremely low concentrations of growth factors, hormones, and pharmaco-toxicological agents in a way conceivably very close to their behaviour in vivo

Gender Differences in Medication Use: A Drug Utilization Study Based on Real World Data

A gender-specific drug utilization study was performed in the Campania region, Southern Italy. Data were based on outpatient drug prescriptions collected from administrative databases. The study population included all patients with at least one drug prescription in 2018. Prevalence was used as a measure to estimate the degree of exposure to drugs. A total of 3,899,360 patients were treated with at least one drug (54.2% females). The number of prescriptions was higher in females than males (55.6% vs. 44.4%). Females recorded higher prevalence for the majority of therapeutic groups (ATC II-anatomical therapeutic chemical), as well as for anti-inflammatory and antirheumatic products drugs (M01) (25.6% vs. 18.7%, risk ratio (RR): 0.73), beta blocking agents (C07) (14.5% vs. 11.6%, RR: 0.80), psychoanaleptics (N06) (7.1% vs. 3.7%, RR: 0.52), and antianemic preparations (B03) (2.8% vs. 6.7%, RR: 0.4). Higher prevalence was identified for males only for drugs used in diabetes (A10) (6.8% vs. 6.2%, RR: 1.1), particularly for biguanides (A10BA). Conversely, treatment duration was longer among males, explaining the higher mean cost per treated patient. This real-world study showed substantial gender differences in terms of medication use and duration of treatment and costs. These results are relevant to promoting and supporting the emerging role of precision and personalized medicine

Experimental Tests on a Near-Field to Far-Field Transformation Technique Using a Nonconventional Plane-Rectangular Scanning

This work concerns the experimental validation of an efficient near-field – far-field (NF–FF) transformation using a nonconventional plane-rectangular scanning, particularly suitable from the NF data reduction and time saving viewpoints when dealing with quasi-planar antennas. Such a NF scanning technique has been named planar wide-mesh scanning, since the sample grid is characterized by meshes wider and wider when going away from the center. It relies on the use of the nonredundant sampling representation of electromagnetic fields based on the oblate ellipsoidal modelling of the antenna. An optimal sampling interpolation scheme is then used to efficiently recover the NF data needed by the probe compensated NF–FF transformation with the standard plane-rectangular scanning. The experimental tests, carried out at the planar NF facility of the antenna characterization laboratories of Selex ES, have fully confirmed the effectiveness of this technique
