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.

Gas-loaded nanocarriers (G-LN) show promise in improving heart transplantation (HTx) outcomes. Given their success in reducing cell death during normothermic hypoxia/reoxygenation (H/R) in vitro, we tested their integration into cardioplegic solutions and static cold storage (SCS) during simulated HTx. Wistar rat hearts underwent four hours of SCS with four G-LN variants: O2- or N2-cyclic-nigerosyl-nigerose-nanomonomers (CNN), and O2- or N2-cyclic-nigerosyl-nigerose-nanosponges (CNN-NS). We monitored physiological-hemodynamic parameters and molecular markers during reperfusion to assess cell damage/protection. Hearts treated with nanomonomers (N2-CNN or O2-CNN) showed improvements in left ventricular developed pressure (LVDP) and a trend towards faster recovery of the rate pressure product (RPP) compared to controls. However, nanosponges (N2-CNN-NS or O2-CNN-NS) did not show similar improvements. None of the groups exhibited an increase in diastolic left ventricular pressure (contracture index) during reperfusion. Redox markers and apoptosis/autophagy pathways indicated an increase in Beclin 1 for O2-CNN and in p22phox for N2-CNN, suggesting alterations in autophagy and the redox environment during late reperfusion, which might explain the gradual decline in heart performance. The study highlights the potential of nanomonomers to improve early cardiac performance and mitigate cold/H/R-induced stunning in HTx. These early improvements suggest a promising avenue for increasing HTx success. Nevertheless, further research and optimization are needed before clinical application.

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.

Vitamin D3 (VitD3) plays a crucial role in various cellular functions through its receptor interaction. The biological activity of Vitamin D3 can vary based on its solubility and stability. Thus, the challenge lies in maximizing its biological effects through its complexation within cyclodextrin (βNS-CDI 1:4) nanosponges (NS) (defined as VitD3NS). Therefore, its activity has been evaluated on two different gut–brain axes (healthy gut/degenerative brain and inflammatory bowel syndrome gut/degenerative brain axis). At the gut level, VitD3-NS mitigated liposaccharide-induced damage (100 ng/mL; for 48 h), restoring viability, integrity, and activity of tight junctions and reducing ROS production, lipid peroxidation, and cytokines levels. Following intestinal transit, VitD3-NS improved the neurodegenerative condition in the healthy axis and the IBS model, suggesting the ability of VitD3-NS to preserve efficacy and beneficial effects even in IBS conditions. In conclusion, this study demonstrates the ability of this novel form of VitD3, named VitD3-NS, to act on the gut–brain axis in healthy and damaged conditions, emphasizing enhanced biological activity through VitD3 complexation, as such complexation increases the beneficial effect of vitamin D3 in both the gut and brain by about 50%.
