Abstract
BACKGROUND In chronic wounds, high concentrations of matrix metalloproteinases (MMPs) can cause excessive proteolysis and slow wound healing. Consequently, restoring a proper MMP balance can help reduce the risk of a chronic wound. An antiseptic solution containing 0.05% sodium hypochlorite (Amukine Med 0.05%, Angelini S.p.A.; hereafter termed NaClO solution) is available on the market. The NaClO solution was proven effective and safe in managing infected skin wounds. To further characterize its activity, this study evaluated the in vitro activity of the NaClO solution on the monocyte release of MMPs. METHODS Human monocytic THP-1 (ATCC® TIB-202™) cell lines were differentiated into macrophages and treated with different concentrations of NaClO (from 0.05% to 5 × 10-7%). In addition, the THP-1 cell line was stimulated with wound fluid (WF) from patients with active venous leg ulcers in the inflammatory phase. The effect of NaClO (0.025-0.0062%) was also evaluated on healthy human peripheral blood serum samples. The effects of treatments on the gelatinolytic activity of MMP-9 were evaluated by gelatin zymography. The effects on MMPs release were evaluated through the Pro™ Human MMP 9-plex Assay. An exploratory scratch wound healing assay was also performed. RESULTS The NaClO solution reduced the gelatinolytic activity of MMP-9 and its activated form. The downregulation of MMP-9 gelatinolytic activity was also observed in peripheral blood serum. The MMPs profile showed a reduction in MMP-1 release (p < 0.05) and a slight reduction of the release of MMP-9 and MMP-12 after the treatment with LPS and the NaClO solution. A slight improvement in wound healing was observed after macrophage activation and treatment with the NaClO solution. CONCLUSIONS The results obtained suggest a possible ability of the NaClO solution to modulate the proteolytic pathways in the wound microenvironment, further characterizing its activity and use in clinical practice during wound care.

Abstract
Thermoregulation and heat dissipation by sweat production and evaporation are vital for human survival. However, hyperhidrosis or excessive perspiration might affect people's quality of life by causing discomfort and stress. The prolonged use of classical antiperspirants, anticholinergic medications or botulinum toxin injections for persistent hyperhidrosis might produce diverse side effects that limit their clinical use. Inspired by botox molecular mode of action, we used an in silico molecular modelling approach to design novel peptides to target neuronal acetylcholine exocytosis by interfering with the Snapin-SNARE complex formation. Our exhaustive design rendered the selection of 11 peptides that decreased calcium-dependent vesicle exocytosis in rat DRG neurons, reducing αCGRP release and TRPV1 inflammatory sensitization. The most potent peptides were palmitoylated peptides SPSR38-4.1 and SPSR98-9.1 that significantly suppressed acetylcholine release in vitro in human LAN-2 neuroblastoma cells. Noteworthy, local acute and chronic administration of SPSR38-4.1 peptide significantly decreased, in a dose-dependent manner, pilocarpine-induced sweating in an in vivo mouse model. Taken together, our in silico approach lead to the identification of active peptides able to attenuate excessive sweating by modulating neuronal acetylcholine exocytosis, and identified peptide SPSR38-4.1 as a promising new antihyperhidrosis candidate for clinical development.

Abstract
Benzydamine is an active pharmaceutical compound used in the oral care pharmaceutical preparation as NSAID. Beside from its anti-inflammatory action, benzydamine local application effectively reliefs pain showing analgesic and anaesthetic properties. Benzydamine mechanism of action has been characterized on inflammatory cell types and mediators highlighting its capacity to inhibit pro-inflammatory mediators' synthesis and release. On the other hand, the role of benzydamine as neuronal excitability modulator has not yet fully explored. Thus, we studied benzydamine's effect over primary cultured DRG nociceptors excitability and after acute and chronic inflammatory sensitization, as a model to evaluate relative nociceptive response. Benzydamine demonstrated to effectively inhibit neuronal basal excitability reducing its firing frequency and increasing rheobase and afterhyperpolarization amplitude. Its effect was time and dose-dependent. At higher doses, benzydamine induced changes in action potential wavelength, decreasing its height and slightly increasing its duration. Moreover, the compound reduced neuronal acute and chronic inflammatory sensitization. It inhibited neuronal excitability mediated either by an inflammatory cocktail, acidic pH or high external KCl. Notably, higher potency was evidenced under inflammatory sensitized conditions. This effect could be explained either by modulation of inflammatory and/or neuronal sensitizing signalling cascades or by direct modulation of proalgesic and action potential firing initiating ion channels. Apparently, the compound inhibited Nav1.8 channel but had no effect over Kv7.2, Kv7.3, TRPV1 and TRPA1. In conclusion, the obtained results strengthen the analgesic and anti-inflammatory effect of benzydamine, highlighting its mode of action on local pain and inflammatory signalling.

Abstract
Abstract
Objective
The object of the present study is to evaluate factors precluding heart transplantation (HTx) in adult congenital heart disease patients (ACHD) with end-stage heart failure (HF) referred for HTx evaluation.
Methods
This retrospective cohort study enrolled consecutive ACHD patients considered for HTx in our institution between 2014 and 2020 and patients receiving HTx between 2001 and 2013. HTx refusal due to poor candidacy status for excess risk of mortality after transplantation, served as the main study outcome.
Results
Between 2014 and 2020, 46 ACHD patients were evaluated for HTx, 14 ACHD patients underwent HTx between 2001 and 2013. We compared clinical, anatomical and demographic data of 41 patients suitable for transplantation (including both listed/transplanted patients, not yet listed because too well and patients who chose to refuse transplantation) with 15 patients refused after screening (excluding 4 patients with ongoing screening). Risk factors for refusal were: multiple high risk features (odds ratio [OR]: 3.6; 95% confidence interval [CI]: 1.1 to 12.9; p 0.048); anatomical factors (OR: 14.5; 95% CI: 3.1 to 68.4; p 0.001), out-of-center ACHD/HTx program referral (OR: 5.3; 95% CI: 1.5 to 19.0; p 0.01). HTx refusal identifies a high risk ACHD patient subgroup (hazard ratio for overall mortality: 3.1; 95% CI: 1.1 to 8.3; p 0.02).
Conclusions
In our study risk factors for refusal from HTx are adverse anatomical features, multiple conventional HTx high risk factors and out-of-center referral. ACHD patients refused from HTx present shorter time to death. Efforts to increase HTx candidacy are strongly necessary for this growing population.

Abstract
Brain ageing has been related to a decrease in cellular metabolism, to an accumulation of misfolded proteins and to an alteration of the lipid membrane composition. These alterations act as contributive aspects of age‐related memory decline by reducing membrane excitability and neurotransmitter release. In this sense, precursors of phospholipids (PLs) can restore the physiological composition of cellular membranes and ameliorate the cellular defects associated with brain ageing. In particular, phosphatidylcholine (PC) and phosphatidylethanolamine (PE) have been shown to restore mitochondrial function, reduce the accumulation of amyloid beta (Aβ) and, at the same time, provide the amount of acetylcholine needed to reduce memory deficit. Among PL precursors, alpha‐glycerylphosphorylethanolamine (GPE) has shown to protect astrocytes from Aβ injuries and to slow‐down ageing of human neural stem cells. GPE has been evaluated in aged human hippocampal neurons, which are implicated in learning and memory, and constitute a good in vitro model to investigate the beneficial properties of GPE. In order to mimic cellular ageing, the cells have been maintained 21 days in vitro and challenged with GPE. Results of the present paper showed GPE ability to increase PE and PC content, glucose uptake and the activity of the chain respiratory complex I and of the GSK‐3β pathway. Moreover, the nootropic compound showed an increase in the transcriptional/protein levels of neurotrophic and well‐being related genes. Finally, GPE counteracted the accumulation of ageing‐related misfolded proteins (a‐synuclein and tau). Overall, our data underline promising effects of GPE in counteracting cellular alterations related to brain ageing and cognitive decline.

Abstract
AIMS The interaction between common cardiovascular risk factors (CVRF) and hypertrophic cardiomyopathy (HCM) is poorly studied. We sought to explore the relation between CVRF and the clinical characteristics of patients with HCM enrolled in the EURObservational Research Programme (EORP) Cardiomyopathy registry. METHODS AND RESULTS 1739 patients with HCM were studied. The relation between hypertension (HT), diabetes (DM), body mass index (BMI), and clinical traits was analysed. Analyses were stratified according to the presence or absence of a pathogenic variant in a sarcomere gene. The prevalence of HT, DM, and obesity (Ob) was 37, 10, and 21%, respectively. HT, DM, and Ob were associated with older age (P<0.001), less family history of HCM (HT and DM P<0.001), higher New York Heart Association (NYHA) class (P<0.001), atrial fibrillation (HT and DM P<0.001; Ob p = 0.03) and LV (left ventricular) diastolic dysfunction (HT and Ob P<0.001; DM P = 0.003). Stroke was more frequent in HT (P<0.001) and mutation-positive patients with DM (P = 0.02). HT and Ob were associated with higher provocable LV outflow tract gradients (HT P<0.001, Ob P = 0.036). LV hypertrophy was more severe in Ob (P = 0.018). HT and Ob were independently associated with NYHA class (OR 1.419, P = 0.017 and OR 1.584, P = 0.004, respectively). Other associations, including a higher proportion of females in HT and of systolic dysfunction in HT and Ob, were observed only in mutation-positive patients. CONCLUSION Common CVRF are associated with a more severe HCM phenotype, suggesting a proactive management of CVRF should be promoted. An interaction between genotype and CVRF was observed for some traits.

Abstract
Objectives To assess the effects of benzydamine and mouthwashes (MoWs) containing benzydamine on different stages of Candida albicans biofilm: adhesion, formation, persistence, and regrowth (if perturbed). Materials and methods C. albicans CA1398, carrying the bioluminescence ACT1p-gLUC59 fusion product, was employed. Fungal cells were exposed for 1′, 5′, or 15′ to 4 different benzydamine concentrations (0.075 to 0.6%) to 2 mouthwashes (MoWs) containing benzydamine and to a placebo MoW (without benzydamine). Treated cells were tested for adhesion (90 min) and biofilm formation (24-h assay). Next, 24- and 48-h-old biofilms were exposed to benzydamine and MoWs to assess regrowth and persistence, respectively. The effects of benzydamine, MoWs containing benzydamine, and placebo on different biofilm stages were quantified by bioluminescence assay and by the production of quorum sensing (QS) molecules. Results Benzydamine and MoWs containing benzydamine impaired C. albicans ability to adhere and form biofilm, counteracted C. albicans persistence and regrowth, and impaired a 48-h-old biofilm. Some of these effects paralleled with alterations in QS molecule secretion. Conclusions Our results show for the first time that benzydamine and MoWs containing benzydamine impair C. albicans capacity to form biofilm and counteract biofilm persistence and regrowth. Clinical relevance Benzydamine and MoWs containing benzydamine capacity to affect C. albicans biofilm provides an interesting tool to prevent and treat oral candidiasis. Likely, restraining C. albicans colonization through daily oral hygiene may counteract colonization and persistence by other critical oral pathogens, such as Streptococcus mutans, whose increased virulence has been linked to the presence of C. albicans biofilm.

Abstract
Aim: Ethanol is highly effective at inactivating enveloped viruses, including SARS-CoV-2. The aim of this study is to evaluate the virucidal activity of Amuchina Gel Xgerm (74% ethanol) against SARS-CoV-2, according to the European Standard EN14476:2013+A2:2019. Materials & methods: Virucidal activity of the study product was evaluated against SARS-CoV-2 strain USAWA1/2020 in suspension, in the presence of 0.3 g/l of bovine serum albumin. Results: The log10 reduction of SARS-CoV-2 in the presence of bovine serum albumin was ≥4.11 ± 0.12 after 30 s of exposure to the study product (80% dilution). Cytotoxicity was observed in the 100 dilution, affecting the detection limit by 1 log10. Conclusion: Virucidal activity against SARS-CoV-2 supports the effectiveness of this alcohol-based formulation as a prevention measure for COVID-19 illness.

Abstract
Abstract
Purpose
Assessment of longue term follow-up after surgical repair of Complete Atrioventricular Septal Defect (cAVSD). Evaluation of 3D versus standard 2D echocardiographic accuracy during the last follow-up.
Methods
43 patients were included in this study. Mean age at surgical repair was 7 months, 48.8% of patients were male; 67.4% had Down Syndrome. Mean time follow-up was 13 ± 6 years. During the last follow-up 2D and 3D echo evaluation were performed.
Results
All patients were alive and had a NYHA class I at the last follow-up. Survival free from new cardiac surgery at 13 years was 86%. During follow-up a progressive moderate to severe/severe mitral regurgitation (MR) was observed in 6 patients (16.3%) while 4 patients developed a progressive left ventricular outflow tract obstruction (LVOTO); overall 5 patients underwent new cardiac surgery (3 for MR and 2 for LVOTO). Echocardiographic evaluation showed: LV end diastolic volume 55.7 ± 13.0ml/m2, LV ejection fraction 64 ± 5%, left atrium volume 24.9 ± 13.9ml/m2, right ventricle systolic pression 21.0 ± 2.0 and a LVOT gradient 14.6 ± 16.4 mmHg. Mitral valve evaluation is evidenced in Table 1. Predictor factors of severe MR during follow-up were the cleft area and depth and the presence of anterior leaflet prolapse. Cohen’s kappa evidenced a good correlation between 2D and 3D VC evaluation with a higher sensibility of 3D evaluation to identify severe MR, data confirmed by the ROC curve analysis (Figure A and B).
Conclusions
Clinical outcome after cAVSD surgical repair is excellent with a low rate of reintervention. 3D echo evaluation is more sensitive to identify both predictors and severity of MR ì.

Abstract
New topical totally aqueous formulations that improve the low water solubility of minoxidil and realize an adequate permeability of drug in the skin are proposed. These formulations are lacking in propylene glycol and alcohol that are the principal irritant ingredients present in minoxidil commercial solutions. In order to enhance poor water solubility of minoxidil randomly methyl-β-cyclodextrin was used, and four hydrogels such as, calcium alginate, sodium alginate, carbopol 934 and hydroxyethylcellulose were utilized to ensure a prolonged time of contact with the scalp. The inclusion complex minoxidil/methyl-β-cyclodextrin with a molar ratio 1:1 was obtained by freeze drying and evaluated by NMR, FT-IR and DSC analysis. An apparent stability constant of formed inclusion complex was calculated by phase solubility diagram and its value was 400 M(-1). The solid inclusion complex was used to prepare gel formulations with similar dose to minoxidil commercial solution. The gels were evaluated for various technological parameters including rheological behavior, in vitro drug release and ex vivo permeation through pig skin. The best performance was observed for the calcium alginate formulation.

Abstract
In this work we evaluated the ability of 2,6-di-O-methyl-beta-cyclodextrin (DM-beta-Cyd) to include the anti-rhinovirus drug Disoxaril (WIN 51711), increasing its water solubility and stability. The complex, prepared by kneading method, was characterized in the solid state by differential scanning calorimetry and in aqueous solution using circular dichroism and NMR spectroscopy. The formation of 1:1 and 1:2 drug-Cyd complexes was hypothesized. Stability constants for both complexes were determined on the basis of an Ap-type phase solubility diagrams and evidenced a very high stability for the 1:1 complex. Thermodynamic parameters of the binding process showed the existence of classical hydrophobic interactions in the 1:1 complex with the formation of a less ordered system after complexation. An enthalpic contribution rather than an entropic one accompanied the association of the second Cyd molecule. DM-beta-Cyd was able to significantly increase water solubility of WIN 51711, from 0.000123 to 0.47142 mg/ml. Free drug shows a very low water stability, it is completely hydrolyzed after 36 h in PBS (pH 7.0), at 4 degrees C. In the presence of DM-beta-Cyd only a 10% of WIN 51711 was degraded, to the same conditions, after 12 days. DM-beta-Cyd increases the permeation of WIN 51711 across excised bovine nasal mucosa mounted on Franz cells, with respect to the free drug. Nevertheless, the permeation process had a lag time of 2 h so that the drug might assure its pharmacological activity on the outer surface of the mucosa. In vivo studies on rabbits evidenced that WIN 51711 is well tolerated, having no observable effect on the nasal mucosa following repeated administration.

Abstract
The acylethanolamide anandamide (AEA) occurs in a variety of mammalian tissues and, as a result of its action on cannabinoid receptors, exhibits several cannabimimetic activities. Moreover, some of its effects are mediated through interaction with an ion channel-type vanilloid receptor. However, the chemical features of AEA suggest that some of its biological effects could be related to physical interactions with the lipidic part of the membrane. The present work studies the effect of AEA-induced structural modifications of the dipalmitoylphosphatidylcholine (DPPC) bilayer on phospholipase A2 (PLA2) activity, which is strictly dependent on lipid bilayer features. This study, performed by 2-dimethylamino-(6-lauroyl)-naphthalene fluorescence, demonstrates that the effect of AEA on PLA2 activity is concentration-dependent. In fact, at low AEA/DPPC molar ratios (from R = 0.001 to R = 0.04), there is an increase of the enzymatic activity, which is completely inhibited for R = 0.1. X-ray diffraction data indicate that the AEA affects DPPC membrane structural properties in a concentration-dependent manner. Because the biphasic effect of increasing AEA concentrations on PLA2 activity is related to the induced modifications of membrane bilayer structural properties, we suggest that AEA-phospholipid interactions may be important to produce, at least in part, some of the similarly biphasic responses of some physiological activities to increasing concentrations of AEA.

Abstract
BACKGROUND Breast reconstruction after a mastectomy, today is considered the best choice to improve the quality of life for the patient. The aim of the procedure is to consider the aesthetic results obtained and the various involvements, comparing them with those already reported in literature. METHODS. There is no certain data of the number of breast reconstructions performed in Italy in the few years. In 1999, in Veneto, reconstruction surgery after total breast removal, represented only 16% of the operations. In our surgery Division, from 1996 to 2000, there were breast reconstructions performed, either immediately or delayed on 87 patients out of 118 after mastectomy. 73.7% none over the age of 60 (range 27-60). The breast removal technique used is the Madden, while, for the reconstruction we have put into effect the submuscle prosthetic implant; 63 patients were subject to follow-up treatment during the period of 10 to 36 months. RESULTS Seventy-eight percent of the women have judged the final aesthetic results the same or better than expected. Based on reconstruction with prosthesis, is the preferred procedure, even with serious complications which do not always influence the final results. This preference is because of the reduced operation time and the psychological and physical benefits due to immediate restoral of the mammary volume and shape. CONCLUSIONS Some problems (Garavaglia Law) have slowed down the diffusion in Italy of this type of treatment which is now receiving more and more request and approval by the women affected with breast cancer.

Abstract
We have investigated by immuno-electron microscopy the presence of phosphotyrosine in cells as a whole and in different cell districts (nucleus, cytoplasm, plasma membrane, and mitochondria) in peripheral blood lymphocytes of IDDM (insulin-dependent diabetes mellitus) patients and age-matched controls. Immuno-gold particle density was highest in mitochondria and decreased in cytoplasm, nucleus and plasma membrane. The time dependence of phosphotyrosine labelling after cell isolation was very strong in all subcellular populations, with a fall in immunogold staining after 30 min. Staining levels at zero time were similar in controls and IDDM patients; the loss of phosphotyrosine labelling was much stronger in controls, except in the plasma membrane. Plasma membrane NADH oxidoreductase activity, studied using cytosolic NADH as substrate and assayed with DCIP as acceptor, was significantly increased in IDDM patients, suggesting a response to a deficient mitochondrial energetic activity. The fact that NADH oxidoreductase is a growth factor related to tyrosine phosphorylation pathways raises intriguing questions on the cellular derangement occurring in peripheral lymphocytes in IDDM, although the relationships among the immunocytochemical and biochemical changes is still obscure.

Abstract
BACKGROUND Little is known about minimal retinal lesions occurring in the first months of disease in children with type 1 diabetes mellitus (DM). OBJECTIVE To detect any early retinal change and to evaluate its progression in children diagnosed with type 1 DM. PATIENTS From 1979 to 1997 we examined by fluorescein angiography at diagnosis or within 15 months from the onset of DM 130 young patients with type 1 DM (mean age at diagnosis 10.08 +/- 2.62 yr). In 112 patients follow-up by fluorescein angiography was performed every 1.26 years with a mean of 5.41 fluorescein angiographies/patient. METHODS The stage of retinopathy was graded to detect minimal lesions. We also considered sex, pubertal stage, HLA, family history of DM, disease duration and HbA1c levels. RESULTS At first examination, 14 out of 127 (11%) readable angiographies showed minimal retinal changes. There was no statistically significant difference between the patients with or without lesions for all parameters considered. The 112 patients examined during follow-up were divided as follows: Group A: no retinopathy at first examination; Group A1: no retinopathy during follow-up; Group A2: retinal changes during follow-up; Group B: retinal changes at the first examination. Mean HbA1c value evaluated during the whole follow-up was lower in group A1 than in group A2. HbA1c levels at onset of the disease were significantly different in the three groups: in group A1 it was lower than in group A2 and in group B. CONCLUSIONS The presence of early lesions in the first year of disease in 11% of patients is probably due to the method of examination, which may detect even minimal retinal changes. This may be correlated to the acute metabolic failure present at the onset of disease. The prolonged follow-up seems to demonstrate that the early changes are not necessarily a negative prognostic factor in the evolution of diabetic retinopathy. We confirm that duration of DM and metabolic control are the main factors influencing the course of retinopathy in these young patients. Early fluorescein angiography is not particularly useful in the management of children with DM.
