Our work concerns the actual problem of spread of SARS- CoV-2 outbreak which requires fast and correct as possible answer. In current scenario, the need of rapid answer put away the imperative of proper methodology. We focus on the serogical immunoassay for diagnosis of Covid-19 as an important weapon not only for diagnostic purpose, but also for epidemiologic one. The right equilibrium between high speed, low cost and accuracy is obtained with easy-to-use decentralized point-of-care test as the colloidal gold-based immunochromatographic strip assay which detects IgM and IgG antibodies directed against SARS-CoV-2. As our aim is to evaluate the efficacy of Covid-19 rapid tests and of serological assays in real-life settings, we designed a research protocol aimed to establish how to use correctly these diagnostics, taking into account the different possible clinical and epidemiological scenarios.
Acute pancreatitis, the most frequent hospitalization reason in internal medicine ward among gastrointestinal diseases, is burdened by high mortality rate. The disease manifests mainly in a mild form, but about 20-30% patients have a severe progress that requires intensive care. Patients presenting with acute pancreatitis should be clinically evaluated for organ failure signs and symptoms. Stratifying patients in the first days from symptoms onset is essential to determine therapy and care setting. The aim of our study is to evaluate prognostic factors for acute pancreatitis patients, hospitalized in internal medicine wards, and moreover, understanding the role of various prognostic scores validated in intensive care setting in predicting in-hospital mortality and/or admission to intensive care unit. We conducted a retrospective study enrolling all patients with diagnosis of acute pancreatitis admitted took an internal medicine ward between January 2013 and May 2019. Adverse outcome was considered in-hospital mortality and/or admission to intensive care unit. In total, 146 patients (137 with positive outcome and 9 with adverse outcome) were enrolled. The median age was (67.89 ± 16.44), with a slight prevalence of male (55.1%) compared to female (44.9%). C protein reactive (p = 0.02), creatinine (p = 0.01), sodium (p = 0.05), and troponin I (p = 0.013) after 48 h were significantly increased in patients with adverse outcome. In our study, progression in SOFA score independently increases the probability of adverse outcome in patients hospitalized with acute pancreatitis. SOFA score > 5 is highly predictive of in-hospital mortality (O.R. 32.00; C.I. 6.73-152.5; p = 0.001) compared to other scores. The use of an easy tool, validated in intensive care setting such as SOFA score, might help to better stratify the risk of in-hospital mortality and/or clinical worsening in patients hospitalized with acute pancreatitis in internal medicine ward.
A fit-and-well 52-year-old worker, with negative familiar story, was admitted to Emergency Department (ED) with haemodynamically unstable but well bore broad complex tachycardia of 180 b.p.m. (Figure 1). Twenty years before the patient had heart-surgery to repair atrial septal venous sinus defect with patch. The defect determined anomalous pulmonary venous return in right atrium with left to right shunt and moderate pulmonary hypertension. The surgery, 20 years before, was complicated by a single event of supraventricular tachycardia pharmacology resolved. Next follow-up was normal although at transthoracic echocardiography severe right ventricular (RV) dilation was reported. In the ED the patient had palpitation but not chest pain or dyspnoea. General clinical examination was normal but he was hypertensive (170/137 mmHg) and with heart rate of 180 b.p.m. Valsalva manoeuver was performed and adenosine (6 mg–12 mg–12 mg) was administered without benefit. Eventually, the patient was cardioverted to sinus rhythm with a single 100 J shock. His baseline ECG (Figure 2) showed sinus rhythm, normal axis, as well as right bundle branch block and T-wave inversion in leads V1–V4 and a waves with a small spike upward in lead V1 which represent characteristic epsilon waves.
Successively patient was admitted to Cardiology Department where transthoracic echocardiography showed severe RV dilation and moderate hypokinesia with a tricuspid annular plane excursion of 15 mm, TAV 9.6 cm/s, fractional area change of 29%. The right atrium was moderate dilated (volume 70 ml, indexed volume 35.53 ml/m2). Left chambers were normal. No shunts were observed. An electrophysiology study with isoprenaline infusion was performed but no arrhythmias were induced. Cardiac magnetic resonance imaging (MRI) was normal save for global RV dilatation, increased RV end diastolic volume (156 ml/m2), and global RV systolic dysfunction (reduction of RV ejection fraction 31%). Arrhythmogenic cardiomyopathy was excluded as patient’s background suggested RV dilation was due the overload caused by the history of left–right shunt. Blood tests and personal history negative initially exclude myocarditis and cardiac MRI confirmed the absence of oedema. An accurate ECG analysis excluded Brugada syndrome. Following discussion between electrophysiologists, clinical cardiologists, and the patient who first need to be informed, trans-venous ICD was implanted. 179 Figure 1ECG in ED. Figure 2 Baseline ECG.

BACKGROUND: Pasta plays an important role in human nutrition, nevertheless its organoleptic, structural and bromatologic properties have not been completely studied. OBJECTIVE: The study aims to compare the ultrastructure pasta cross-sections produced with reduced mechanic stress and low heat exposure technique (Pietro Massi Technology ™) to common samples obtained with traditional technology in order to assess if a different process can alter the ultrastructure of starch and then, its digestibility. METHODS: A comparative study was performed on the ultrastructure of pasta using scanning electron microscopy (S.E.M). 55 were pasta cross-sections made with Pietro Massi technology, 33 were samples from different pasta factory produced using traditional process, for a total of 88 samples analysed. RESULTS: According to an Index based on what it was observed at one slide at S.E.M we classified samples and compared the number of grains, caves and canals visible, their dimensions in μm and average size of grains. The number of grains in group 1 (9.06±5.01) in group 2 (5.71±5.77), in group 3 (5.93±7.65) resulted significative more elevated compared to group 4 (0.73±2.58); in group 1 and group 2 the number of caves observed was higher than group 4. The size in μm of canals resulted significantly more elevated in group 1 than group 3 (p = 0.008), group 2(p = 0.013), and group 4 (p = 0.02). CONCLUSION: The analysis of average size of caves and canals in μm, the number of caves and grains demonstrated in samples obtained with Massi technology elevated values compared to samples obtained with traditional technique. The number of caves, grains and canals visible in the starch surface demonstrate the high quality of this pasta because they likely ensure penetration of water during cooking, facilitating at the same time the penetration of pancreatic amylases during digestion, suggesting a better digestibility in pasta produced according to this methodology.
