Abstract
Abstract
Introduction
Stent under expansion is one of the main predictors of percutaneous coronary intervention (PCI) failure, being a trigger for both in–stent restenosis and stent thrombosis, with their obvious clinical impact. Among the main causes of stent failure, the presence of a severely calcified lesion is the most frequent and dangerous. Correct recognition and preparation of target lesion are therefore mandatory before stenting.
Methods
We enrolled all the patients treated with angioplasty and IVL (Shockwave Medical Inc, Santa Clara, USA) from October 2020 to October 2021 in our cath lab. Each patient signed informed consent.
Results
We enrolled 35 patients (with 41 lesions treated with IVL). Mean age was 73 years old, 29 were males (82%). Clinical characteristics are shown in the table. Twenty–one lesions (50%) were treated up–stream before stenting, 6 (16%) were bail–out IVL for inadequate stent expansion after post–dilation and 14 (37%) were in–stent restenosis with evidence of stent under–expansion because of the high burden of calcium. Fifty–four per cent of patients were treated in the context of Acute Coronary Syndrome (ACS). Seventy–three per cent of patient had three–vessel disease. The majority of procedure were done through radial access (74%) and 79% of the stenosis was prepared with NC balloons (at least 2.5 mm diameter) before deployment of the IVL balloon; in 2 case IVL was done after rotational atherectomy. Intravascular ultrasound (IVUS) guidance was used in in 15 pts. Two balloon were broken during lithotripsy. In 26 of 41 stenosis (63%) IVL delivery was obtained on a single wire, while 11 required buddy–wire (of whom 8 required child–in–mother technique to obtain adequate support for delivery). We had two major complications: 1 case of ventricular fibrillation (in a patients with recent myocardial infarction and severe reduction of ejection fraction, and 1 case of perforation at the time of inflation of the NC balloon after IVL easily treated with positioning of a covered stent which was easily delivered thanks to the previous IVL treatment).
Conclusion
IVL is a safe and all–around technique for treatment of severely calcified lesion in different clinical contexts from stable coronary artery disease to ACS, useful for upstream calcium treatment as well as bail–out stent optimization and correction of under expansion in calcified in–stent restenosis.

Abstract
COVID 19 has so far found the only barrier in the use of mRNA and viral vector vaccines. Among the rare adverse effects related to mRNA vaccines is myocarditis (4.8 cases per million doses) a disease already found in COVID 19 infection but not in the safety studies of the vaccines. Males not older than 30 years (40% of the total), subjected to the second dose inoculation, are most affected. During our recent clinical practice there was a case of a patient with myocarditis, attributable to vaccination for COVID 19. It was a male, twenty–year–old, non–allergic smoker, subjected to second dose of Pfizer–BioNTech vaccine (BNT162b2). On the fifth day after the inoculation, the patient, already asthenic from the previous days, complained of an episode of oppressive chest pain, which lasted about 15 minutes, which returned, more intense the following night, associated with dyspnea, lasted for hours. When the patient went to the emergency room the pain was in regression and there was good hemodynamic compensation. EKG: sinus rhythm, slight diffuse ST segment elevation, more pronounced in the inferior–lateral leads, slight lowering of the P–R segment. Blood tests: troponin, CKMB and PCR increase, negativity of the molecular test for COVID 19. Echocardiography: normal left ventricle, non–dilated right sections, normokinetic right ventricle, normal valves, pericardial hyper–refraction without effusion, normal diastolic relaxation. In the suspicion of myocarditis, the patient was admitted to our intensive cardiological care. With the high–dose anti–inflammatory and beta–blocker therapy the pain gradually disappeared; never fever; EKG showed progressive ST segment improvement and T wave negativization. Never arrhythmic events. Negativity for all infections with common viral pathogens. MRI: hyperintensity (T2 STIR sequences and late enhancement) in the infero–lateral area. Patient discharged in therapy with lysine acetylsalicylate, to be reduced, associated with pantoprazole, and metoprolol and indicated for outpatient checks. In conclusion, the case presented reflects the scientific literature in the type of patient and in the favorable evolution of the disease.

Abstract
BACKGROUND Published reports on tocilizumab in COVID-19 pneumonitis show conflicting results due to weak designs or heterogeneity in critical methodological issues. METHODS This open-label trial, structured according to Simon's optimal design, aims to identify factors predicting which patients could benefit from anti-IL6 strategies and to enhance the design of unequivocal and reliable future randomized trials. A total of 46 patients with COVID-19 pneumonia needing of oxygen therapy to maintain SO2 > 93% and with recent worsening of lung function received a single infusion of tocilizumab. Clinical and biological markers were measured to test their predictive values. Primary end point was early and sustained clinical response. RESULTS Twenty-one patients fulfilled pre-defined response criteria. Lower levels of IL-6 at 24 h after tocilizumab infusion (P = 0.049) and higher baseline values of PaO2/FiO2 (P = 0.008) predicted a favourable response. CONCLUSIONS Objective clinical response rate overcame the pre-defined threshold of 30%. Efficacy of tocilizumab to improve respiratory function in patients selected according to our inclusion criteria warrants investigations in randomized trials.

Abstract
Abstract
Background
Coronary Aneurysms are a focal dilatation of an artery segment of >1.5-fold the normal size of adjacent segments. Some limited series suggested an incidence of 0.3–12%. However, coronary aneurysms are not mentioned in practice guidelines and several questions remain unanswered.
Purpose
To investigate its clinical profile, prognostic predictors, and long term outcomes.
Methods
The coronary artery aneurysm registry (CAAR, NCT02563626) is a collaborative effort involving 32 hospitals across 9 countries (Canada, Cuba, Czech Republic, Germany, Italy, Netherlands, Spain, USA and Uruguay). When eligibility was uncertain, cases were reviewed by a core lab.
Results
We reviewed 436,467 consecutive angiographies between 2004–2016. 1,565 patients were ambispectively included. Global incidence was 0.35%. Most were male (78.5%) with a mean age of 65 years. Cardiovascular risk factors were frequent. An aortopathy history was present in 8.7% but a Kawasaki antecedent was unfrequent (0.3%).
The main indication for cath was an ACS in 966 cases. Most aneurysms were saccular and 82 giant. The number of aneurisms was low, mainly with 1–2 (95.8%) and only 3 patients with ≥6, proportionally with more coronary stenosis. The most affected artery was the LAD. Aortopathy was related with higher number of aneurysms. Most received any revascularization, commonly percutaneous (PCI). During a follow-up of 37.2 months, 485 suffered a MACE, (death/heart failure/unstable angina/reinfarction) and 240 died. Age, race, diabetes, renal failure, peripheral disease, acute cath, coronary stenosis, LVEF and anticoagulation remained as predictors of death/MACE after multivariate adjustments, without no major differences comparing CABG vs PCI. No restenosis was found in aneurysm with DES but those with BMS suffered 4 (p=0.002). MACE and death were more frequent in patients who received BMS.

Conclusions
Coronary aneurysmal disease is not uncommon. It is associated with severe coronary stenosis and a high cardiovascular risk burden, pointing out an aggressive atherosclerotic status. Antiplatelet therapy is a reasonable option and interventional procedures safe and effective, compared with surgery. Drug eluting stents should be preferred as the default strategy.

Abstract
Identifying the best performing hybrid without a field test was essential to save resources and time. In this study, the genetic divergence was estimated using morphological and expressed sequence tag (EST)-derived simple sequence repeats (SSR) markers. Cluster analysis showed that APMS6A and RPHR 1005 belong to groups I and II, respectively, and the hybrid combination recorded the highest mean grain yield of 32.25 g among generated 40 F1s with standard heterosis of 8.4% over hybrid check, KRH2. The coefficient of marker polymorphism (CMP) value was calculated based on EST-SSRmarkers; it ranged from 0.40 to 0.80, and a higher CMP value of 0.80 was obtained for the parental combination APMS6A × RPHR1005. We predicted heterosis for 40 F1s based on correlation between CMP and standard heterosis in different traits with standard varietal and hybrid checks indicating positive correlation and significant value for grain yield per plant (r = 0.58**),productivity per day (r = 0.54**), productive tillers (r = 0.34*) and panicle weight (r = 0.42**). This study revealed that the relationship of molecular marker heterozygosity, along with the combining ability, high mean value of different traits,grouping of parental lines based on morphological and molecular characterization is helpful to identify heterotic patterns in rice.

Abstract
Cardiac natriuretic peptides (NP) are involved in cardiorenal regulation and in lipolysis. The NP activity is largely dependent on the ratio between the signaling receptor NPRA and the clearance receptor NPRC. Lipolysis increases when NPRC is reduced by starving or very-low-calorie diet. On the contrary, insulin is an antilipolytic hormone that increases sodium retention, suggesting a possible functional link with NP. We examined the insulin-mediated regulation of NP receptors in differentiated human adipocytes and tested the association of NP receptor expression in visceral adipose tissue (VAT) with metabolic profiles of patients undergoing renal surgery. Differentiated human adipocytes from VAT and Simpson-Golabi-Behmel Syndrome (SGBS) adipocyte cell line were treated with insulin in the presence of high-glucose or low-glucose media to study NP receptors and insulin/glucose-regulated pathways. Fasting blood samples and VAT samples were taken from patients on the day of renal surgery. We observed a potent insulin-mediated and glucose-dependent upregulation of NPRC, through the phosphatidylinositol 3-kinase pathway, associated with lower lipolysis in differentiated adipocytes. No effect was observed on NPRA. Low-glucose medium, used to simulate in vivo starving conditions, hampered the insulin effect on NPRC through modulation of insulin/glucose-regulated pathways, allowing atrial natriuretic peptide to induce lipolysis and thermogenic genes. An expression ratio in favor of NPRC in adipose tissue was associated with higher fasting insulinemia, HOMA-IR, and atherogenic lipid levels. Insulin/glucose-dependent NPRC induction in adipocytes might be a key factor linking hyperinsulinemia, metabolic syndrome, and higher blood pressure by reducing NP effects on adipocytes.

Abstract
Within the last few years, the presence of bentazone herbicide has been observed in many water resources. For the first time, removal of bentazone using mesoporous silica was investigated revealing reversible adsorption. The adsorption isotherm was well described using the Freundlich model. The affinity towards bentazone is strongly affected by pH in the range of 2-7, decreasing with the increase of the pH, becoming negligible at the neutrality. Regeneration of the adsorbent was possible, and a recovery as high as 70 % was obtained using CH3OH-NaOH solution. Furthermore, appreciable recovery (47 %) was also obtained using water. Applications on the purification of lake water and wastewaters, both characterized by a significant organic carbon load, spiked with 2 mg L(-1) bentazone were tested, observing removal yields in the range of 61-73 %. Taking advantage of the fast adsorption kinetics observed, an in-flow purification treatment was set-up, with quantitative removal of bentazone from polluted water.

Abstract
Kidney transplantation is now recognized as the treatment of choice for patients with chronic renal failure. Despite the extension of indications to patients suffering severe hypertension, ischemic heart disease, and chronic heart failure, the worldwide results are superb. However, perioperative cardiac complications occur in 6% to 10% of transplanted patients. Aggressive intraoperative volume expansion is still recommended to maximize graft functional recovery (up to 30 mL/kg/h, central venous pressure [CVP] > 15 mm Hg), but patients with preexistent cardiac disease or poor myocardial function are exposed to the risk of fluid overload, acute respiratory failure, and prolonged ventilation. Among the last 90 cases performed at our institution, good functional recovery of the graft was present in 94% of the patients within 2 weeks, despite a much more conservative intraoperative hydration policy (crystalloids 2400 +/- 1000 mL, 15 mL/kg/h, CVP 7-9 mm Hg). Graft failure which occurred in 5 patients was significantly correlated only with donor age, while perioperative cardiovascular complications had been present in 9 cases (10%) who were coronary artery disease patients (55%). Age above 50 years was the only significant risk factor. Supranormal volume loading is probably not always warranted in kidney transplantation.

Abstract
Believed to be due to unbalance between cerebrospinal fluid (CSF) production rate and its loss through the spinal dural puncture hole, post-dural puncture headache (PDPH) is often considered as a physiological syndrome, usually reversible without pathological sequelae after dural hole's closure. The clinical case here presented (incapacitating headache associated with diagnostic dural puncture in a leukaemic young female patient who underwent bone marrow transplantation) shows potentially fatal pathological sequelae following prolonged headache (untreated, due to the severe postransplant immunodeficiency and coagulopathy). The observed RMI lesions suggest interesting conclusions about the clinical indications and correct timing of autologous epidural blood patch (EBP). We also suggest the ways to preventing rebound intracranial hypertension following autologous epidural blood patch in patients suffering from incapacitating and prolonged headache.

Abstract
The naphthoquinones 2-hydroxy-3-(1,1-dimethylallyl)-1,4-naphthoquinone (CS-1), (-)-2,3,3-trimethyl-2-3-dihydronaphtho[2,3-b]furan-4,9-quinone (CS-3), and 2-acetoxy-3-(1,1-dimethylallyl)-1,4-naphthoquinone (CS-5) isolated from Calceolaria sessilis were tested against Trypanosoma cruzi epimastigotes, the TA3 tumor cell line and the methotrexate-resistant subline TA3-MTX-R. Naphthoquinone CS-3 was the most active; the 50% culture growth inhibition (I50) on T. cruzi (Tulahuén and LQ strain and DM28c clone) was at concentrations ranging from 2.1 to 5.2 mumolar. Also CS-3 inhibited TA3 and TA3-MTX-R culture growth with an I50 of 2.1 and 3.8 mumolar, respectively. Naphthoquinone CS-3 inhibited the respiration of the tumor cells by interfering with the electron transport at some point between NADH and ubiquinone. The respiration of T. cruzi was not inhibited by naphthoquinone CS-3. Naphthoquinone CS-3 produced a temporary increase of oxygen consumption in T. cruzi and tumor cells, suggesting the generation and participation of free radicals.

Abstract
The effects of nordihydroguaiaretic acid (NDGA), best known as an inhibitor of lipoxygenase activities, on the culture growth, oxygen consumption, ATP level, viability, and redox state of some electron carriers of intact TA3 and 786A ascites tumor cells have been studied. NDGA inhibited the respiration rate of these two tumor cell lines by preventing electron flow through the respiratory chain. Consequently, ATP levels, cell viability and culture growth rates were decreased. NDGA did not noticeably inhibit electron flow through both cytochrome oxidase and ubiquinone-cytochrome b-c1 complex. Also, the presence of NDGA changed to redox state of NAD(P)+ to a more reduced level, and the redox states of ubiquinone, cytochrome b and cytochromes c + c1 changed to a more oxidized level. These observations suggest that the electron transport in the tumor mitochondria was inhibited by NDGA at the NADH-dehydrogenase-ubiquinone level (energy-conserving site 1). As a consequence, mitochondrial ATP synthesis would be interrupted. This event could be related to the cytotoxic effect of NDGA.

Abstract
Visual evoked potentials (VEP) were recorded in 20 children undergoing dialysis for chronic renal failure. VEP before treatment (72 h after last dialysis) were pathological in 17 patients (85%); responses obtained 3 h after treatment were abnormal in only 6 cases (30%). Furthermore, all patients improved after treatment, except two who were unchanged. However, VEP recorded immediately after dialysis were worse in 4 of 7 patients than before treatment, probably as an effect of the dysequilibrium syndrome; they improved spontaneously afterwards. The acute changes caused by dialysis seem to be more evident in children than in adults. No correlations have been found between blood chemistry indexes and VEP modifications. Finally, VEP have proved to be more sensitive than EEG in identifying a central nervous system (CNS) dysfunction in these uremic patients.

Abstract
A case of spasmodic torticollis with thoracic outlet syndrome observed for over 18 months is presented and discussed. Maximal head rotation (determining backward gaze) was associated with compression of the brachial plexus between the scaleni muscles and motor, sensory and trophic troubles in the hand. This new syndrome is called after the diviner Manto, quoted by Dante Alighieri in his 'Divina Commedia' (Inferno, XX, 52-56). The etiology was ascribed to subacute toxic effects of methylparathion. Brainstem Auditory Evoked Potentials (BAEPs) demonstrated severe brainstem involvement, maximal in the mesencephalic structures. Clinical and neurophysiological data improved on treatment with L-5-hydroxytryptophan. Finally, BAEPs returned to normal.
