Drug use during pregnancy should be evidence-based and favor the safest and most appropriate prescription. The Italian Medicines Agency (AIFA) coordinates a network focusing on monitoring medication use in pregnancy. Hypertensive disorders are common medical complication of pregnancy and antihypertensive therapy is prescribed to reduce the risk of adverse feto-maternal complications. The objective of this study is to highlight the prescription pattern of antihypertensive drugs before pregnancy, during pregnancy and in the postpartum period in Italy and to evaluate their use with a specific attention to the prescription pattern of drugs considered safe during pregnancy. A multi-database cross-sectional population study using a Common Data Model (CDM) was performed. We selected all women aged 15–49 years living in eight Italian regions who gave birth in hospital between 1 April 2016 and 31 March 2018. In a cohort of 449.012 women, corresponding to 59% of Italian deliveries occurred in the study period, the prevalence of prescription of antihypertensive drugs in the pre-conceptional period was 1.2%, in pregnancy 2.0% and in the postpartum period 2.9%. Beta-blockers were the most prescribed drugs before pregnancy (0.28%–0.30%). Calcium channel blockers were the most prescribed drugs during pregnancy, with a prevalence of 0.23%, 0.33%, 0.75% in each trimester. Alfa-2-adrenergic receptor agonists were the second most prescribed during pregnancy with a prevalence of 0.16%, 0.26% and 0.55% in each trimester. The prescription of drugs contraindicated during pregnancy was below 0.5%. Only a small percentage of women switched from a contraindicated drug to a drug compatible with pregnancy. The analysis showed little variability between the different Italian regions. In general, the prescription of antihypertensive drugs in the Italian Mom-Network is coherent with the drugs compatible with pregnancy.

Bioactive compounds are naturally occurring substances that have the ability to have physiological impacts on the human body. Due to their potential health advantages and their function in preventing and treating a variety of serious health risks, also this substances shown a high antibacterial and antibiofilm activities against bacteria that can affect health. Therefore, the purpose of the current investigation was to test different bioactive compounds (Thymol, Quercetin, Epicatechin gallate, Gallic acid, Coumarin, Caffeic acid, Tannic acid, Apigenin, Carvacrol, Carvone, Beta ionone and Eucalyptol), in order to see there effect against B. cereus. Additionally, the contact angle method was used to examine the influence of those substances on the physicochemical characteristics of PLA 3D printing material and there antiadhesive effect against bacteria studied. According to the antibacterial activities it should be noted that Carvacrol, Tannic acid and Epicatechin gallate were the most active against B. cereus bacteria. The measurements of the contact angle showed a substantial change in the physicochemical characteristics of 3D printing PLA, indicating an improvement in the electron donor character after treatment, and significantly changed the surface hydrophobicity following treatment from hydrophobe PLA to hydrophile PLA after treatement, we can also see that B. cereus can adhere to PLA before treatment but after treatment with bioactive compounds it has become unfavorable which means that our select compounds are indeed active. After the use of computational methods like ADMET analysis, molecular docking and dynamic analysis, it was practical to better understand the physicochemical and pharmacokinetic proprieties, drug-likeness, antibacterial antiadhesive properties of the studied phytocomponents.

The current study applied electrospun fibers containing 8-hydroxyquinoline-5-sulfonic acid (8-HQS) (100, 150, and 200 mg L−1) and silver nitrate (AgNO3) (15 and 20 mg L−1) to enhance the longevity and qualitative parameters of two cyclamen cultivars. The results indicated that the vase life of the flowers treated with 20 mg L−1 AgNO3 and 200 mg L−1 8-HQS was higher than that of the other treatments (16 days). Cyclamens treated with 8-HQS (100 mg L−1) + AgNO3 (15 mg L−1) and 8-HQS (100 mg L−1) + AgNO3 (20 mg L−1) had lower polyphenol oxidase (PPO) activity than the control group. Also, it was observed that the higher phenylalanine ammonia-lyase (PAL) enzyme activity of cyclamens in the 8-HQS (150 mg L−1) + AgNO3 (15 mg L−1) treatment was longer than that of the other treatments and control groups. Treatment with 100 mg L−1 8-HQS and 20 mg L−1 AgNO3 showed higher peroxidase (POD) activity than the different treatments. This research indicated that adding AgNO3 and 8-HQS to electrospun fibers is a promising method for enhancing the longevity and maintaining the quality of these cut flowers.

The ability to employ waste products, such as vegetable scraps, as raw materials for the synthesis of new promising adsorbing materials is at the base of the circular economy and end of waste concepts. Dextrin-based nanosponges (D_NS), both cyclodextrin (CD) and maltodextrin (MD), have shown remarkable adsorption abilities in the removal of toxic compounds from water and wastewater, thus representing a bio-based low-cost solution which is establishing itself in the market. Nevertheless, their environmental safety for either aquatic or terrestrial organisms has been overlooked, raising concern in terms of potential hazards to natural ecosystems. Here, the environmental safety (ecosafety) of six newly synthesized batches of D_NS was determined along with their full characterization by means of dynamic light scattering (DLS), thermogravimetric analysis (TGA), Fourier transformed infrared spectroscopy with attenuated total reflection (FTIR-ATR) and transmission electron microscopy (SEM). Ecotoxicity evaluation was performed using a battery of model organisms and ecotoxicity assays, such as the microalgae growth inhibition test using the freshwater Raphidocelis subcapitata and the marine diatom Dunaliella tertiolecta, regeneration assay using the freshwater cnidarian Hydra vulgaris and immobilization assay with the marine brine shrimp Artemia franciscana. Impact on seedling germination of a terrestrial plant of commercial interest, Cucurbita pepo was also investigated. Ecotoxicity data showed mild to low toxicity of the six batches, up to 1 mg/mL, in the following order: R. subcapitata > H. vulgaris > D. tertiolecta > A. franciscana > C. pepo. The only exception was represented by one batch (NS-Q+_BDE_(GLU2) which resulted highly toxic for both freshwater species, R. subcapitata and H. vulgaris. Those criticalities were solved with the synthesis of a fresh new batch and were hence attributed to the single synthesis and not to the specific D_NS formulation. No effect on germination of pumpkin but rather more a stimulative effect was observed. To our knowledge this is the first evaluation of the environmental safety of D_ NS. As such we emphasize that current formulations and exposure levels in the range of mg/mL do not harm aquatic and terrestrial species thus representing an ecosafe solution also for environmental applications.

Introduction: There are an estimated 26 million rare disease patients in Europe, about 2 million in Italy. Access to orphan drugs has been evaluated nationally and internationally, and delays have been observed due to evaluation of price and therapeutic value. The objectives of this study are: to assess the availability of EMA-authorized orphan drugs at national and regional level; to study time trends and regional variability in consumption and spending, and to estimate the time to access in Italian regions. Methods: We evaluate the availability of EMA authorized orphan drugs in Italy. Based on data from the Traceability of medicines dataflow for period 2016-2021 we evaluate the expenditure, consumption and availability of orphan drugs in each region. To estimate the time to access we consider the days between the end of negotiation procedure and the first purchase by regions. Results: In 2021 in Italy are available 94% of EMA authorized orphan drugs. The expenditure and consumption have grown during the last decade. The availability is higher in bigger regions, that also take care of patients from smaller regions. The pro capite expenditure and consumption in DDD/1,000 ab die is similar in all the geographic area. Time to regional access is on average 123 days, that grows to 224 excluding the orphan drugs dispensed before the end of reimbursement procedure.

BackgroundMany countries use the WHO Essential Medicines List (EML) as a guide for health policy choices to promote the efficient use of healthcare resources or adopt the concept of essential medicines (EMs) to develop their own national list of essential medicines. The aim of this study is to analyse the availability and use of medicines included in the 22nd WHO EML in Italy.MethodsUsing the ATC code (5th level), a comparison was made between the medicines included in the WHO EML and those retrieved from the Italian Medicines Agency (AIFA) database. The availability (regulatory and reimbursement status) of EMs, as well as the market share in expenditure (million euros) and consumption [measured in WHO-defined daily doses (DDDs)], compared to all reimbursed medicines in 2021, were analysed.ResultsIn 2021, approximately 85.2% (n = 414) of medicines included in the WHO EML were commonly marketed in Italy. Of these, 396 EMs were fully reimbursed by the Italian National Healthcare Service (INHS), corresponding to 81.5% (396/486) of the WHO EML, while the remaining 18.5% (90/486) were neither authorised (n = 72) nor reimbursed (n = 18). The study found a low coverage for anti-parasitic, insecticides, and repellent products (ATC P) in addition to medicines for the genitourinary system and sex hormones (ATC G). Even though medicines on the WHO EML, including therapeutic alternatives, accounted for ~48.5% of the expenditure for medicines reimbursed by INHS, the list covered 74% of all national drug consumed. Novel high-cost therapies indicated in high-prevalence diseases and rare conditions, mostly antineoplastic and immune-modulating agents (ATC L) not included in the WHO EML, were also guaranteed.ConclusionsIn Italy, high coverage of EMs was found. It was largely reimbursed by the INHS, even when compared to other European countries. Essential medicines represented a high percentage of the overall expenditure and consumption in Italy. The WHO EML could be an important tool to guide the health policy choices of high-income countries, although a more frequent update and easier access to information on rejected medicines are needed.

The development of polymers obtained from renewable sources such as polysaccharides has gained scientific and industrial attention. Cross-linked bio-derived cationic polymers were synthesized via a sustainable approach exploiting a commercial maltodextrin product, namely, Glucidex 2®, as the building block, while diglycidyl ethers and triglycidyl ethers were used as the cross-linking agents. The polymer products were characterized via FTIR-ATR, TGA, DSC, XRD, SEM, elemental analysis, and zeta-potential measurements, to investigate their composition, structure, and properties. Polydispersed amorphous granules displaying thermal stabilities higher than 250 °C, nitrogen contents ranging from 0.8 wt % and 1.1 wt %, and zeta potential values between 10 mV and 15 mV were observed. Subsequently, water absorption capacity measurements ranging from 800% to 1500%, cross-linking density determination, and rheological evaluations demonstrated the promising gel-forming properties of the studied systems. Finally, nitrate, sulfate, and phosphate removal tests were performed to assess the possibility of employing the studied polymer products as suitable sorbents for water remediation. The results obtained from the ion chromatography technique showed high sorption rates, with 80% of nitrates, over 90% of sulfates, and total phosphates removal.

Cyclodextrin-based nanosponges (CD-NSs) have gained importance in drug delivery in the last years due to their easy synthesis and versatility. However, their use as carriers for the delivery of macromolecules such as proteins is less known and sometimes difficult to consider. In this entry, the authors summarize and highlight the multiple possibilities of CD-NSs to deliver active proteins, improving their activity or stability. Starting with a brief description of CD-NSs and their characteristics, the entry will be focused on several proteins, such as (1) Lipase, (2) Insulin and (3) Nisin, for chemical or pharmaceutical applications. The revised results demonstrated that CD-NSs can generate different and interesting applications with proteins. These results could be added to their uses with small drugs, being an interesting alternative for protein delivery and applicability.

Pharmaceuticals such as salicylic acid are commonly detected in wastewater and surface waters, increasing concern for possible harmful effects on humans and the environment. Their difficult removal via conventional treatments raised the need for improved strategies, among which the development of bioderived adsorbents gained interest because of their sustainability and circularity. In this work, biobased cross-linked adsorbents, synthesized via a sustainable approach from starch derivatives, namely beta-cyclodextrins and maltodextrins, were at first characterized via FTIR-ATR, TGA, SEM, and elemental analysis, showing hydrophilic granular morphologies endowed with specific interaction sites and thermal stabilities higher than 300 °C. Subsequently, adsorption tests were carried out, aiming to assess the capabilities of such polymers on the removal of salicylic acid, as a case study, from water. Batch tests showed rapid kinetics of adsorption with a removal of salicylic acid higher than 90% and a maximum adsorption capacity of 17 mg/g. Accordingly, continuous fixed bed adsorption tests confirmed the good interaction between the polymers and salicylic acid, while the recycling of the adsorbents was successfully performed up to four cycles of use.

Nanosponges can favour the gradual release of molecules over a prolonged time, increasing the bioavailability and action of preservatives and phytoregulators, reducing the concentrations usually adopted. In floriculture, they have previously been proposed for the delivery of anti-ethylene compounds to improve the shelf-life of cut flowers. However, the potential of nanosponges is not only limited to these compounds. The present study evaluated the effects of β-cyclodextrin-based nanosponges and growth regulators on the post-harvest longevity of cut flowers of ornamental species. One novelty was the use of Forchlorfenuron (CPPU), a growth regulator belonging to the group of cytokinins predominantly used in fruit cultivation, to evaluate its potential to increase the shelf-life of cut carnations (Dhiantus caryophyllus). Specifically, as far as post-harvest longevity is concerned, the treatments involved the use of: deionised water; nanosponges and deionised water; nanosponges loaded with CPPU; nanosponges loaded with a classic solution for cut flowers, composed of sucrose, aluminium sulphate and 8-hydroxyquinoline sulphate. Preliminary results show that the nanosponge and deionised water complex and the nanosponge and classical solution complex prolonged the longevity of the cut flower by up to 20 days, compared to the control (17 days). In contrast, the CPPU-nanosponge complex showed similar results to the control. Replication of the research is necessary to validate the results.

BackgroundItaly has the highest per capita alcohol consumption among European countries. Several pharmacological treatments for alcohol use disorders (AUDs) are currently available in Italy, but no consumption data are available. A first analysis of national drug consumption, comprising the whole Italian population over a long-term period covering the COVID-19 pandemic, was performed.MethodsTo analyze the consumption of medications indicated for therapy of alcohol dependence, different national data sources were used. Consumption was measured as a defined daily dose (DDD) per 1,000,000 inhabitants per day.ResultsIn 2020, the total consumption of medicines used in the treatment of AUDs amounted to 310.3 DDD per 1 million inhabitants per day (0.018% of the overall drug consumption in Italy) with a decreasing gradient from the north (373.9 DDD) to the south (250.7 DDD). 53.2% of the overall doses were dispensed by public healthcare facilities and 23.5% by community pharmacies, while the remaining 23.3% were purchased privately. The temporal trend of consumption seemed to be stable across the last few years, although an impact of the COVID-19 pandemic was observed. Disulfiram was the most consumed medicine over years.ConclusionAll Italian regions offer pharmacological treatments to patients with AUDs, but differences in the number of dispensed doses suggest a different local organization of patient care, which can be partly explained by the different severity of the clinical condition of residing patients. Pharmacotherapy of alcoholism should be deeply investigated to describe the clinical characteristics of treated patients (i.e., comorbidities) and evaluate the appropriateness of prescribed medications.

BackgroundThe use of medications during pregnancy is a common event worldwide. Monitoring medicine prescriptions in clinical practice is a necessary step in assessing the impact of therapeutic choices in pregnant women as well as the adherence to clinical guidelines. The aim of this study was to provide prevalence data on medication use before, during and after pregnancy in the Italian population.MethodsA retrospective prevalence study using administrative healthcare databases was conducted. A cohort of 449,012 pregnant women (15-49 years) residing in eight Italian regions (59% of national population), who delivered in 2016-2018, were enrolled. The prevalence of medication use was estimated as the proportion (%) of pregnant women with any prescription.ResultsAbout 73.1% of enrolled women received at least one drug prescription during pregnancy, 57.1% in pre-pregnancy and 59.3% in postpartum period. The prevalence of drug prescriptions increased with maternal age, especially during the 1st trimester of pregnancy. The most prescribed medicine was folic acid (34.6%), followed by progesterone (19%), both concentrated in 1st trimester of pregnancy (29.2% and 14.8%, respectively). Eight of the top 30 most prescribed medications were antibiotics, whose prevalence was higher during 2nd trimester of pregnancy in women ≥ 40 years (21.6%). An increase in prescriptions of anti-hypertensives, antidiabetics, thyroid hormone and heparin preparations was observed during pregnancy; on the contrary, a decrease was found for chronic therapies, such as anti-epileptics or lipid-modifying agents.ConclusionsThis study represents the largest and most representative population-based study illustrating the medication prescription patterns before, during and after pregnancy in Italy. The observed prescriptive trends were comparable to those reported in other European countries. Given the limited information on medication use in Italian pregnant women, the performed analyses provide an updated overview of drug prescribing in this population, which can help to identify critical aspects in clinical practice and to improve the medical care of pregnant and childbearing women in Italy.

Abstract Background and aim Evidence on determinants of prices for orphan medicines is scarce and not available for Italy. The aim of this paper is to provide an evidence on variables affecting the annual treatment cost of orphan drugs in Italy, testing the hypothesis of a negative correlation with the dimension of the target population and a positive correlation with the added therapeutic value of the drug and the quality of the evidence of pivotal studies. Methods Drugs with a European orphan designation reimbursed in Italy in the last 6 years (2014–2019) were considered. Univariate, cluster analysis and multiple regression models were used to investigate the correlation between the annual treatment cost and, as explanatory variables, the dimension of the target population, the existence of Randomized Clinical Trials as a proxy of the quality of the pivotal studies, the added therapeutic value. Results In the univariate analysis prevalence and added therapeutic value, as expected, have a negative and positive correlation with cost respectively. The correlation with RCT is not significant. In the multivariate model, coefficients for prevalence and added value are confirmed but for the latter are not significant anymore. We also found, through an interaction analysis, that the existence of an RCT has a positive impact on annual treatment cost when the target population is very small. Conclusions Our results suggest that value arguments and sustainability (dimension of the target population and its impact on budget impact) issues are considered for orphan drugs pricing: the role played by sustainability is systematically supported by our results. A more transparent and reproducible price negotiation process for orphan drugs is needed in Italy. This paper has contributed to highlight the implicit drivers of this process.

The ageing process is associated with an increased probability of accumulating health deficits, chronic conditions and geriatric syndromes, leading to a growing prevalence of multimorbidity, defined as the co-occurrence of two or more chronic conditions (of which, at least one physical condition). One of the most frequent and direct consequences of multimorbidity, especially amongst older adults, is polypharmacy, a condition characterized by the concomitant use of five or more drugs per day. Polypharmacy is one of the main risk factors for adverse clinical outcomes, including drug-drug interactions and adverse drug reactions, also resulting in increased hospitalizations, morbidity, and increased use of healthcare resources, with considerable implications for healthcare costs. Deprescribing is one of potential approaches to reduce inappropriate prescribing and it is defined as the stopping or dose reduction of medications that are either inappropriate or unnecessary, especially among patients with polypharmacy. In this review, the major issues associated with polypharmacy among older people, the current guidelines for the management of polypharmacy and the strategies to implement deprescribing in different settings (i.e., hospital setting, nursing homes and general practice) are discussed.

ObjectiveThis investigation aimed to guarantee the principles of transparency in public administration; to inform citizens about the time to patient access to reimbursed medicines; to assess the duration of the P&R process for the first time in the period 2018–2020; and to evaluate whether and how the SARS-CoV-2 (COVID-19) pandemic affected the P&R activity. This study analyzed the timelines of pricing and reimbursement procedures submitted in Italy by the pharmaceutical marketing authorization holder (MAH) from 2018 to 2020.MethodsThe analysis was run through an AIFA web-based platform that collects data about P&R procedures for each step of the Italian Price and Reimbursement (P&R) procedure, including dates of the Technical Scientific Committee (CTS) and Price and Reimbursement Committee (CPR) meetings from January 2018 to December 2020. On this basis, four indicators were developed relating to the completion time of each stage of the P&R negotiation process and were defined in terms of days. In this regard, descriptive analyses, graphical boxplots, and survival curves (Kaplan–Meier) were carried out, studying these indicators in relation to the typology of pharmaceutical procedures.ResultsOverall, in the period 2018–2020, 57.1% of the 2,445 procedures entered were represented by the Off-patent pharmaceuticals procedures (generics, biosimilars, copies, and/or parallel trade). In 2020, the overall process duration for Off-patent pharmaceuticals procedures was equal to 129.8 average days [95% CI: (122.3–137.2)], with a median value of 108.0, whereas for In-patent pharmaceuticals procedures, it was equal to 283.1 average days [95% CI: (267.8–298.5)], with a median value of 284.0. Over time, the trend of the entire duration of the P&R process tended to decrease. In terms of estimated timing for the conclusion of each stage of the P&R negotiation process, the difference between Off-patent and In-patent pharmaceutical procedures was statistically significant by the Log-Rank test.Discussion and conclusionThis is the first study to examine the time of the P&R process in Italy, from MAH submission to the publication of the final decision in the Italian Official Journal. The time span considered is 3 years, including the first year of the COVID-19 pandemic. Compared to European average times, in Italy, the time necessary for evaluation, authorization for reimbursement, and definition of the price of a medicine can be considered satisfactory.

IntroductionThe aim of the study was to evaluate, in a regulated generics market, the effect of the number of manufacturers of generic drugs on the amplitude of off-patent products price reduction and the price evolution of originators and generics after the patent expiry of pharmaceuticals dispensed by community pharmacies and reimbursed by the Italian National Health Service (INHS).MethodsThe AIFA “transparency list” was utilized to select unbranded and branded off-patent drug dispensed by community pharmacies and reimbursed by the Italian National Health Service between 2012 and 2018. The unbranded drug entry in the transparency list database was considered as a proxy of its patent expiry.ResultsA total of 42 different active ingredients were included in the analysis. The relative price per dose at time t of unbranded and branded drugs, considering as common denominator the price per dose a year before the patent expiry, (t-1) decreased with the increase of unbranded manufacturers. At the time of the patent expiry, the price of unbranded drugs was almost 50% less than that of branded drugs at t-1 and the price of branded drugs started to decrease before the first unbranded entry.ConclusionAn inverse relation between the number of generic drug entrants and the price of generics and originators was detected. The patent expiry determines a price decline, more concentrated in the first year of patent expiry.

AimsHuman epicardial adipose tissue, a dynamic source of multiple bioactive factors, holds a close functional and anatomic relationship with the epicardial coronary arteries and communicates with the coronary artery wall through paracrine and vasocrine secretions. We explored the hypothesis that T-cell recruitment into epicardial adipose tissue (EAT) in patients with non-ST segment elevation myocardial infarction (NSTEMI) could be part of a specific antigen-driven response implicated in acute coronary syndrome onset and progression.Methods and ResultsWe enrolled 32 NSTEMI patients and 34 chronic coronary syndrome (CCS) patients undergoing coronary artery bypass grafting (CABG) and 12 mitral valve disease (MVD) patients undergoing surgery. We performed EAT proteome profiling on pooled specimens from three NSTEMI and three CCS patients. We performed T-cell receptor (TCR) spectratyping and CDR3 sequencing in EAT and peripheral blood mononuclear cells of 29 NSTEMI, 31 CCS, and 12 MVD patients. We then used computational modeling studies to predict interactions of the TCR beta chain variable region (TRBV) and explore sequence alignments. The EAT proteome profiling displayed a higher content of pro-inflammatory molecules (CD31, CHI3L1, CRP, EMPRINN, ENG, IL-17, IL-33, MMP-9, MPO, NGAL, RBP-4, RETN, VDB) in NSTEMI as compared to CCS (P < 0.0001). CDR3-beta spectratyping showed a TRBV21 enrichment in EAT of NSTEMI (12/29 patients; 41%) as compared with CCS (1/31 patients; 3%) and MVD (none) (ANOVA for trend P < 0.001). Of note, 11/12 (92%) NSTEMI patients with TRBV21 perturbation were at their first manifestation of ACS. Four patients with the first event shared a distinctive TRBV21-CDR3 sequence of 178 bp length and 2/4 were carriers of the human leukocyte antigen (HLA)-A*03:01 allele. A 3D analysis predicted the most likely epitope able to bind HLA-A3*01 and interact with the TRBV21-CDR3 sequence of 178 bp length, while the alignment results were consistent with microbial DNA sequences.ConclusionsOur study revealed a unique immune signature of the epicardial adipose tissue, which led to a 3D modeling of the TCRBV/peptide/HLA-A3 complex, in acute coronary syndrome patients at their first event, paving the way for epitope-driven therapeutic strategies.

Cyclodextrin nanosponges (CD-NS) are nanostructured crosslinked polymers made up of cyclodextrins. The reactive hydroxy groups of CDs allow them to act as multifunctional monomers capable of crosslinking to bi- or multifunctional chemicals. The most common NS synthetic pathway consists in dissolving the chosen CD and an appropriate crosslinker in organic polar aprotic liquids (e.g., N,N-dimethylformamide or dimethyl sulfoxide), which affect the final result, especially for potential biomedical applications. This article describes a new, green synthetic pathway through mechanochemistry, in particular via ball milling and using 1,1-carbonyldiimidazole as the crosslinker. The polymer obtained exhibited the same characteristics as a CD-based carbonate NS synthesized in a solvent. Moreover, after the synthesis, the polymer was easily functionalized through the reaction of the nucleophilic carboxylic group with three different organic dyes (fluorescein, methyl red, and rhodamine B) and the still reactive imidazoyl carbonyl group of the NS.

Background: Evidence-based recommendations for outpatient management of COVID-19 were published by the Italian Medicines Agency (AIFA) to limit the use of off-label treatments. The aim of this study is to measure the use of outpatient drug treatments in a COVID-19-positive population, taking into account the Italian regulatory agency’s advices.Methods: A descriptive observational study was conducted. All patients testing positive for COVID-19 residing in Lazio region, Italy, with diagnosis date between March 2020 and May 2021 were selected, and outpatient medicine prescription patterns were identified.Results: Independent of AIFA recommendations, the use of drug therapy in the management of outpatient COVID-19 cases was frequent (about one-third of the cases). The most used drug therapy was antibiotics, specifically azithromycin, despite the negative recommendation of AIFA, while the use of corticosteroids increased after the positive recommendation of regulatory agency for the use in subjects with severe COVID-19 disease. The use of hydroxychloroquine was limited to the early pandemic period where evidence on its potential benefit was controversial. Antithrombotics were widely used in outpatient settings, even if their use was recommended for hospitalized patients.Conclusion: In this study, we show a frequent use of drug therapy in the management of outpatient cases of COVID-19, mainly attributable to antibiotics use. Our research highlights the discrepancy between recommendations for care and clinical practice and the need for strategies to bridge gaps in evidence-informed decision-making.

IntroductionIt is well acknowledged that the price of orphan drugs is normally higher than that resulting from the value-based pricing. A correlation between the cost of therapy for orphan drugs and the epidemiology (prevalence and incidence) of the related rare disease can be hypothesized.MethodsThis analysis includes all approved orphan drugs by European Medicines Agency whose reimbursement was granted for the first therapeutic indication in the years 2014–2019 in Italy. Regression and correlation analyses were performed to analyze the possible correlations between the logarithm of the annual therapy cost and the epidemiology of the rare diseases, between orphan drugs consumption and epidemiology of related rare disease and between therapy cost and the consumption.ResultsThe regression analysis between the annual cost of therapy estimated on the published ex-factory price and the prevalence showed a slightly decreasing, not statistically significant, trend (coefficient: −0.10, p-value: 0.41). The results were similar when using the price resulting from the application of Managed Entry Agreements (coefficient: −0.11, p-value: 0.40). The regression analysis between sales volume and prevalence showed a positive slope without an acceptable level of significance (p-value: 0.04). The correlation analysis between the therapy cost and the sales volume highlighted again an absence of significant association, similarly if considering only ATC L orphan drugs, or the incidence.DiscussionThe definition of the price of an orphan drug seems not to depend on the rarity of the disease, and sales volumes do not correlate with the epidemiology of the rare disease and with the annual cost of therapy.

Antimicrobial resistance (AMR) represents a major issue in healthcare being correlated to global inappropriate use of antibiotics. The aim of this study was to compare the data on hospital antibiotic consumption in 2020–2021 with those related to 2019 in order to evaluate the impact of the COVID-19 pandemic on antibiotic prescriptions and appropriate use at national level and in the different geographical areas. To estimate the consumption of antibiotics, two indicators were calculated: “number of DDD per 1000 inhabitants per day” and “number of DDD per 100 hospitalisation days”. Consumption data on antibiotics dispensed in public health facilities were based on the Italian “traceability of medicines” information flow. Data on hospitalisation days were extracted from the Italian “hospital discharge form” flow. Pearson correlation analysis was performed between the number of patients hospitalised for COVID-19 and the consumption of antibiotics in public healthcare facilities. During 2020, about 1.7 DDD/1000 inhabitants per day (12.3% of the overall consumption of reimbursed antibiotics) were dispensed exclusively in Italian hospitals (+0.8% compared to 2019). Considering the number of DDD per 100 hospitalisation days, consumption increased by 19.3% in 2020 compared to 2019. Comparing the first semester of 2020 and 2019, a decrease of DDD/1000 inhabitants per day was observed (−1.6%) at national level, with opposite trends in the different geographical areas; an increase in the use of azithromycin and carbapenems was also observed, with a stable consumption of third-generation cephalosporins. The use of antibiotics in the second semester of 2020 compared to the same period of 2019 showed a clear reduction at national level (−8.5%), appreciable to a similar extent in all geographic areas. In the first semester of 2021 compared to the same period of 2020, there was a huge reduction (−31.4%) in consumption at national level. However, the variations were heterogeneous between different geographical areas. To our knowledge, this study represents the most comprehensive analysis performed on antibiotic consumption data in hospital settings in Italy during the COVID-19 pandemic to date. Despite international and national guideline recommendations, a substantial overall increase in antibiotic prescriptions was observed during the COVID-19 pandemic, with variability in terms of geographical distribution and prescription strategies. These findings may be related to the dichotomy between perceived and real significance of guidelines, expert panels, or consensus. Therefore, new approaches or strategies to antimicrobial stewardship should be proposed.

Objectives: Starting from April 2017, the Italian Medicine Agency (AIFA) has approved new criteria for defining any new medicinal product with an innovative indication. The purpose of the study is to analyze the activity of innovativeness evaluation according to the new approach, to estimate the weight of each criterion considered for innovativeness definition, and to evaluate how the new approach works in terms of consistency and reproducibility.Methods: A retrospective analysis was performed on the final reports evaluating the drug innovativeness assessment published on the AIFA's website between April 2017 and January 2021. Descriptive statistics, chi-square test, whether the conditions were respected, or Fisher's exact test was used to explore the association between characteristics of drugs and the innovativeness status and the association between the three criteria. Profiles of the decision process and their relationship with innovativeness response were described. In order to evaluate the weight of each criterion in predicting the innovativeness status, a Classification Tree (CT) algorithm was applied.Results: Overall, of the 109 published drugs reports, 37 (33.9%) were recognized as fully innovative, 29 (26.6%) were considered conditionally innovative, while for 43 (39.4%) reports innovativeness was not recognized. Considering the three criteria of the decision process, the added therapeutic value was the only criterion statistically associated with a drug's degree of innovation (p < 0.001). The therapeutic need and the quality of clinical evidence were statistically associated (p = 0.008) even if only a mild association was observed. The added therapeutic value was the most important variable in predicting the innovativeness status according to the classification tree (CT) model applied, achieving an accuracy of 89.4%. No difference was found between orphans and non-orphan drugs or oncological and non-oncological drugs.Discussion: The added therapeutic value is the most important criterion of the multidimensional approach for the innovativeness status definition of a new medical product. A mild association was found between the therapeutic need and the quality of evidence. Overall, similar decision profiles bring the same evaluation of innovativeness status, indicating a good consistency and reproducibility between decisions.

In this article, we used monolayer two dimensional (2D) and 3D multicellular spheroid models to improve our understanding of the gene delivery process of a new modified cationic hyper-branched cyclodextrin-based polymer (Ppoly)-loaded plasmid encoding Enhanced Green Fluorescent Protein (EGFP). A comparison between the cytotoxicity effect and transfection efficiency of the plasmid DNA (pDNA)-loaded Ppoly system in 2D and 3D spheroid cells determined that the transfection efficiency and cytotoxicity of Ppoly–pDNA nanocomplexes were lower in 3D spheroids than in 2D monolayer cells. Furthermore, histopathology visualization of Ppoly–pDNA complex cellular uptake in 3D spheroids demonstrated that Ppoly penetrated into the inner layers. This study indicated that the Ppoly, as a non-viral gene delivery system in complex with pDNA, is hemocompatible, non-toxic, high in encapsulation efficiency, and has good transfection efficiency in both 2D and 3D cell cultures compared to free pDNA and lipofectamine (as the control).

This study tested the anticoagulant effect of cyclodextrin (CD) hyper-branched-based polymers (HBCD-Pols). These polymers were synthesized and tested for their coagulant characteristics in vitro and in vivo. Due to their polymeric structure and anionic nature, the polymers can chelate Ca2+, reducing the free quantity in blood. HBCD-Pol increased the blood clotting time, PT, and aPTT 3.5 times over the control, showing a better effect than even ethylenediaminetetraacetic acid (EDTA), as occured with recalcification time as well. A titration of HBCD-Pol and EDTA showed exciting differences in the ability to complex Ca2+ between both materials. Before executing in vivo studies, a hemocompatibility study was carried out with less than 5% red blood cell hemolysis. The fibrinogen consumption and bleeding time were analyzed in vivo. The fibrinogen was considerably decreased in the presence of HBCD-Pol in a higher grade than EDTA, while the bleeding time was longer with HBCD-Pols. The results demonstrate that the anticoagulant effect of this HBCD-Pol opens novel therapy possibilities due to the possible transport of drugs in this carrier. This would give combinatorial effects and a potential novel anticoagulant therapy with HBCD-Pol per se.

Circulating parathyroid hormone (PTH) concentrations increase in heart failure (HF) and are related to disease severity. The relationship between PTH and congestion is still a matter of debate. The objective of this analysis was to evaluate the role of PTH as a marker of congestion and prognosis in HF. We enrolled 228 patients with HF. Intact PTH concentrations and HYDRA score (constituted by: B-type natriuretic peptide, blood urea nitrogen–creatinine ratio, estimated plasma volume status, and hydration status) were evaluated. The study endpoint was all-cause mortality. PTH levels were higher in acute compared with chronic HF and in patients with clinical signs of congestion (i.e., peripheral oedema and orthopnea). PTH concentrations significantly correlated with NYHA class and HYDRA score. At multivariate analysis of HYDRA score, estimated glomerular filtration rate (eGFR), and corrected serum calcium were independently determinants of PTH variability. Fifty patients (22%) died after a median follow-up of 408 days (interquartile range: 283–573). Using univariate Cox regression analysis, PTH concentrations were associated with mortality (hazard ratio [HR]: 1.003, optimal cut-off: >249 pg/mL—area under-the-curve = 0.64). Using multivariate Cox regression analysis, PTH was no longer associated with death, whereas HYDRA score, left ventricular ejection fraction, and eGFR acted as independent predictors for mortality (HR: 1.96, 0.97, and 0.98, respectively). Our study demonstrated that intact PTH was related to clinical and subclinical markers of congestion. However, intact PTH did not act as an independent determinant of all-cause death in HF patients.

Abstract Background Assessment and rating of Parkinson’s Disease (PD) are commonly based on the medical observation of several clinical manifestations, including the analysis of motor activities. In particular, medical specialists refer to the MDS-UPDRS (Movement Disorder Society – sponsored revision of Unified Parkinson’s Disease Rating Scale) that is the most widely used clinical scale for PD rating. However, clinical scales rely on the observation of some subtle motor phenomena that are either difficult to capture with human eyes or could be misclassified. This limitation motivated several researchers to develop intelligent systems based on machine learning algorithms able to automatically recognize the PD. Nevertheless, most of the previous studies investigated the classification between healthy subjects and PD patients without considering the automatic rating of different levels of severity. Methods In this context, we implemented a simple and low-cost clinical tool that can extract postural and kinematic features with the Microsoft Kinect v2 sensor in order to classify and rate PD. Thirty participants were enrolled for the purpose of the present study: sixteen PD patients rated according to MDS-UPDRS and fourteen healthy paired subjects. In order to investigate the motor abilities of the upper and lower body, we acquired and analyzed three main motor tasks: (1) gait, (2) finger tapping, and (3) foot tapping. After preliminary feature selection, different classifiers based on Support Vector Machine (SVM) and Artificial Neural Networks (ANN) were trained and evaluated for the best solution. Results Concerning the gait analysis, results showed that the ANN classifier performed the best by reaching 89.4% of accuracy with only nine features in diagnosis PD and 95.0% of accuracy with only six features in rating PD severity. Regarding the finger and foot tapping analysis, results showed that an SVM using the extracted features was able to classify healthy subjects versus PD patients with great performances by reaching 87.1% of accuracy. The results of the classification between mild and moderate PD patients indicated that the foot tapping features were the most representative ones to discriminate (81.0% of accuracy). Conclusions The results of this study have shown how a low-cost vision-based system can automatically detect subtle phenomena featuring the PD. Our findings suggest that the proposed tool can support medical specialists in the assessment and rating of PD patients in a real clinical scenario.

Macrolides are widely used antibiotics with a broad spectrum of activity. The development of drug carriers to deliver this type of antibiotics has attracted much research. The present study aims at developing new swellable dextrin-based nanohydrogels for the topical delivery of rokitamycin, as model macrolide. Rokitamycin is a synthetic analogous of macrolides with advantageous characteristics as far as bacterial uptake and post-antibiotic effect are concerned. It is also indicated for the treatment of severe infections caused by Acanthamoeba and for topical infections. The nanohydrogels have been prepared from two types of cross-linked polymers obtained by using β-cyclodextrin or Linecaps® was provided by the Roquette Italia SPA (Cassano Spinola, Al, Italy) as building blocks. The cross-linked polymers have been then formulated into aqueous nanosuspensions refined and tuned to achieve the incorporation of the drug. Cross-linked β-cyclodextrin (β-CD) and Linecaps® (LC) polymers formed dextrin-based nanohydrogels with high swelling degree and mucoadhesion capability. Rokitamycin was loaded into the nanohydrogels displaying an average size around 200 nm with negative surface charge. In vitro kinetic profiles of free and loaded drug in nanohydrogels were compared at two pH levels. Interestingly, a sustained and controlled release was obtained at skin pH level due to the high degree of swelling and a pH responsiveness possibly. The results collected suggest that these nanohydrogels are promising for the delivery of rokitamycin and may pave the way for the topical delivery of other macrolide antibiotics.

As the most common cancer in women, efforts have been made to develop novel nanomedicine-based therapeutics for breast cancer. In the present study, the in silico curcumin (Cur) properties were investigated, and we found some important drawbacks of Cur. To enhance cancer therapeutics of Cur, three different nonionic surfactants (span 20, 60, and 80) were used to prepare various Cur-loaded niosomes (Nio-Cur). Then, fabricated Nio-Cur were decorated with folic acid (FA) and polyethylene glycol (PEG) for breast cancer suppression. For PEG-FA@Nio-Cur, the gene expression levels of Bax and p53 were higher compared to free drug and Nio-Cur. With PEG-FA-decorated Nio-Cur, levels of Bcl2 were lower than the free drug and Nio-Cur. When MCF7 and 4T1 cell uptake tests of PEG-FA@Nio-Cur and Nio-Cur were investigated, the results showed that the PEG-FA-modified niosomes exhibited the most preponderant endocytosis. In vitro experiments demonstrate that PEG-FA@Nio-Cur is a promising strategy for the delivery of Cur in breast cancer therapy. Breast cancer cells absorbed the prepared nanoformulations and exhibited sustained drug release characteristics.

There is an acute need for research to acquire high-quality information on the use of medicines in pregnancy, both in terms of appropriateness and safety. For this purpose, the Italian Medicines Agency established a Network for Monitoring Medication use in pregnancy (MoM-Net) through the conduction of population-based studies using administrative data available at regional level. This paper aimed to describe the experiences and challenges within the network. MoM-Net currently involves eight regions and several experts from public and academic institutions. The first study conducted aimed to identify drug use before, during and after pregnancy investigating specific therapeutic categories, analysing regional variability and monitoring drug use in specific subpopulations (i.e. foreign women/multiple pregnancies). Aggregated demographic, clinical, and prescription data were analysed using a distributed network approach based on common data model. The study population included all women delivering during 2016–2018 in the participating regions (n = 449,012), and corresponding to 59% of deliveries in Italy. Seventy-three per cent of the cohort had at least one drug prescription during pregnancy, compared to 57% before and 59% after pregnancy. In general, a good adherence to guidelines for pregnant women was found although some drug categories at risk of inappropriateness, such as progestins and antibiotics, were prescribed. A strong variability in the use of drugs among regions and in specific subpopulations was observed. The MoM-Net represents a valuable surveillance system on the use of medicines in pregnancy, available to monitor drug categories at high risk of inappropriateness and to investigate health needs in specific regions or subpopulations.
