The supply of deep-sea containerised shipping services in the northern italian port systems

In this paper, a review of deep-sea liner shipping services to/from Northern Italian ports is performed.The first section focuses on the analysis of statistical data regarding Italian foreing trade: with special reference to incoming and outcoming freight volumes transported by sea. The Italian import and export volumes with the rest of the world, during the years 2000 – 2010, are reported; in particular the trade by sea between Italy and Asia, in the years 2000 – 2010, is analysed. The development of containerised traffic at Italian ports, which represents the vast majority of global non-bulk freight flows, is shown. The statistics analysed show that the effects of the economic crisis are still in force, and the overall Italian maritime trade decreased in 2009, the year following the onset of the crisis, and rose again in 2010. In the second part of the paper deep-sea services in the northern Italian port systems have been considered. The list of deep-sea services and the values of the total DWT (deadweight tonnage, in thousands of tons) of the containerships departed (in the period of analysis: January 2011) from the North-Western Italian multiport gateway system are reported. The list of deep-sea services and the values of total DWT at the North-Easter Italian multiport gateway system is considered. The routes of containerships departed from North-Western Italian ports and the routes of containerships departed from North-Eastern Italian ports (North Adriatic Italian ports), in January 2011, are shown. The performed survey shows clearly that the main international routes connect Italian ports to the Red Sea and East Asia as well as to US ports. Other routes which connect Italian ports to South America, to Africa and to Oceania are only minor routes. North-western ports have several deep-sea departures, whereas Adriatic ports still play a minor role; the majority of the containerships directed to the Adriatic Sea refer to the Short Sea Shipping network. But it must be pointed out that the economic development of Central and Eastern EU countries and the extension of the Trans-European Transport Network towards the East could contribute to add and/or shift towards the Adriatic Sea some deep-sea services

Potential for rupture before eruption at Campi Flegrei caldera, Southern Italy

Volcanoes reawakening after long repose must rupture the crust before magma can erupt. Rupture is preceded by repeatable variations in the rate of seismicity with ground movement, which trace the amount of applied stress that is released by local earthquakes. A rupturing sequence has been developing across four episodes of ground uplift at Italy’s Campi Flegrei caldera: in 1950-1952, 1969-1972, 1982-1984 and since 2004. We predicted in 2016 that the approach to rupture would continue after an additional uplift of 30-40 cm at the location of largest movement. We have updated our analysis with new data on changes in the numbers of local earthquakes with amounts of ground movement. Here we show that subsequent events have confirmed our prediction and that the unrest has been changing the structure of Campi Flegrei’s crust. The results provide new constraints for evaluating the volcano’s potential to erupt or to subside without eruption

The use of functional tests and planned coronary angiography after percutaneous coronary revascularization in clinical practice. Results from the AFTER multicenter study

Background: The follow-up strategies after percutaneous coronary intervention (PCI) have relevant clinical and economic implications. The purpose of this prospective observational multicenter study was to evaluate the effect of clinical, procedural and organizational variables on the execution of functional testing (FT) and planned coronary angiography (CA) after PCI, and to assess the impact of American College of Cardiology (ACC)/American Heart Association (AHA) guidelines on clinical practice. Methods: Four hundred twenty consecutive patients undergoing PCI were categorized as class I, IIB and III indications for follow-up FT according to ACC/AHA guidelines recommendations. Furthermore, all patients were grouped according to the presence or absence of FT and/or planned CA over 12 months after PCI. Multivariable analysis was used to assess the potential predictors of test execution. Results: During the 12-month follow-up at least one test was performed in 72% of patients with class I indication, 63% of patients with class IIB indication and 75% of patients with class III indication (p=ns). A total of 283 patients (67%) underwent testing. The use of tests was associated with younger age (R. R. 0.94, C. I. 0.91 +/- 0.97, p<0.001), a lower number of diseased vessels (R.R. 0.60, C.I. 0.43 +/- 0.84, p=0.003), follow-up by the center performing PCI (R. R. 2.64, C. I. 1.43 +/- 4.86, p=0.002), and the specific center at which PCI was performed. Most asymptomatic patients completed their testing prematurely with respect to the risk period for restenosis. Conclusions: The use of FT and planned CA after PCI is unrelated to patient's symptom status, and depends on patient's age and logistics. ACC/AHA guidelines have no influence in clinical practice, and test timing is not tailored to the risk period for restenosis. (C) 2008 Elsevier Ireland Ltd. All rights reserved

Application of a pharmacokinetic/pharmacogenetic approach to assess the nicotine metabolic profile of smokers in the real-life setting

The nicotine metabolite ratio, i.e., the ratio 3-hydroxycotinine/cotinine, is used to assess the nicotine metabolic status and has been proven to predict the response to smoking cessation treatments in randomized clinical trials. In the current study, a pharmacokinetic-pharmacogenetic integrated approach is described, based on the development of a liquid chromatography–tandem mass spectrometry (LC/MS/MS) method for nicotine metabolite ratio assay in plasma and a real-time PCR analysis for fast genotyping of CYP2A6. The pharmacokinetic-pharmacogenetic approach was validated in 66 subjects with different smoking status. The LC/MS/MS assay was rapid and sensitive enough to detect plasma cotinine levels also in second-hand exposed abstainers. In the cohort of patients of the present study the following results were obtained: (i) the frequencies of CYP2A6 genetic variants were comparable with those from clinical trials carried out in Caucasian populations; (ii) all the subjects carrying the CYP2A6 deficient allele also had a slow metabolizer phenotype; (iii) slow metabolizers had mean nicotine metabolite ratio approximately 50% of that of the normal/fast metabolizers; (iv) women had higher nicotine metabolite ratio than men; and (v) salivary nicotine metabolite ratio measures were comparable to plasma levels. Overall, the findings of the current study demonstrate that the simultaneous assessment of nicotine metabolite ratio and CYP2A6 genotype from human blood samples is feasible and accurate and could be used in a smoking cessation program to optimize treatments and identify those smokers who inherit metabolically deficient CYP2A6 alleles

Interplay between COVID-19, pollution, and weather features on changes in the incidence of acute coronary syndromes in early 2020

Coronavirus disease 2019 (COVID-19) has caused an unprecedented change in the apparent epidemiology of acute coronary syndromes (ACS). However, the interplay between this disease, changes in pollution, climate, and aversion to activation of emergency medical services represents a challenging conundrum. We aimed at appraising the impact of COVID-19, weather, and environment features on the occurrence of ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) in a large Italian region and metropolitan area

Real-life Diagnostic and Therapeutic Approach to CLL: A New Proposal from an Expert Panel in Tuscany Region

BACKGROUND: In the last years genomic and somatic alterations have shown to play a pivotal role in the pathogenesis of chronic lymphocytic leukemia (CLL) and new prognostic factors have been identified accordingly.AIM: To describe a real-life diagnostic and therapeutic approach to CLL that takes into account the role of genomic and somatic prognostic factors in the risk stratification of developing progressive disease, and treatment decision.METHODS: This new proposal has been developed and validated by ten key opinion leaders from Tuscany Region during two Expert Meetings. The approach suggested comes from their experience in daily clinical practice and is supported by guidelines recommendations, clinical trials results, and drugs prescribing conditions in Italy.RESULTS: Beside TP53 deletion or mutated status, the Expert Panel highlighted the importance of the IGHV mutation status characterization, since the diagnosis, in order to identify patients who will have a more aggressive progression. Furthermore, just before starting treatment, to obtain useful prognostic information and indication in the selection of the therapy, they recommend cytogenetic analysis for the detection of del(11q), trisomy 12, del(13q), del(17p), conventional karyotyping of stimulated CLL cells, TP53 sequencing, and molecular genetic analysis to detect IGHV mutation status.CONCLUSIONS: The Expert Panel recognized the limitations associated with traditional staging systems in identifying patients who will have a more aggressive disease course and predicting response to treatment and suggested a real-life diagnostic and therapeutic approach to CLL to update the current patient management in light of recent advances that have improved understanding of CLL

A highly endemic area of Echinococcus multilocularis identified through a comparative re-assessment of prevalence in the red fox (Vulpes vulpes), Alto Adige (Italy: 2019-2020)

Surveillance of Echinococcus multilocularis at the edge of its range is hindered by fragmented distributional patterns and low prevalence in definitive hosts. Thus, tests with adequate levels of sensitivity are especially important for discriminating between infected and non-infected areas. In this study we reassessed the prevalence of E. multilocularis at the southern border of its distribution in Province of Bolzano (Alto Adige, northeastern Alps, Italy), to improve surveillance in wildlife and provide more accurate estimates of exposure risk. We compared the diagnostic test currently implemented for surveillance based on coproscopy and multiplex PCR (CMPCR) to a real-time quantitative PCR (qPCR) in 235 fox faeces collected in 2019 and 2020. The performances of the two tests were estimated using a scraping technique (SFCT) applied to the small intestines of a subsample (n = 123) of the same foxes as the reference standard. True prevalence was calculated and the sample size required by each faecal test for the detection of the parasite was then estimated. True prevalence of E. multilocularis in foxes (14.3%) was markedly higher than reported in the last decade, which was never more than 5% from 2012 to 2018 in the same area. In addition, qPCR showed a much higher sensitivity (83%) compared to CMPCR (21%) and agreement with the reference standard was far higher for qPCR (0.816) than CMPCR (0.298) meaning that for the latter protocol, a smaller sample size would be required to detect the disease. Alto Adige should be considered a highly endemic area. Routine surveillance on definitive hosts at the edges of the E. multilocularis distribution should be applied to smaller geographic areas, and rapid, sensitive diagnostic tools using directly host faeces, such as qPCR, should be adopted

Contribution of KRAS mutations and c.2369C > T (p.T790M) EGFR to acquired resistance to EGFR-TKIs in EGFR mutant NSCLC: a study on circulating tumor DNA

INTRODUCTION: KRAS oncogene mutations (MUTKRAS) drive resistance to EGFR inhibition by providing alternative signaling as demonstrated in colo-rectal cancer. In non-small cell lung cancer (NSCLC), the efficacy of treatment with EGFR tyrosine kinase inhibitors (EGFR-TKIs) depends on activating EGFR mutations (MUTEGFR). However, inhibition of EGFR may select resistant cells displaying alternative signaling, i.e., KRAS, or restoration of EGFR activity due to additional MUTEGFR, i.e., the c.2369C &gt; T (p.T790MEGFR). AIM: The aim of this study was to investigate the appearance of MUTKRAS during EGFR-TKI treatment and their contribution to drug resistance. METHODS: This study used cell-free circulating tumor DNA (cftDNA) to evaluate the appearance of codon 12 MUTKRAS and p.T790MEGFR mutations in 33 advanced NSCLC patients progressing after an EGFR-TKI. RESULTS: p.T790MEGFR was detected in 11 (33.3%) patients, MUTKRAS at codon 12 in 3 (9.1%) while both p.T790MEGFR and MUTKRAS codon 12 were found in 13 (39.4%) patients. Six patients (18.2%) were KRAS wild-type (WTKRAS) and negative for p.T790MEGFR. In 8 subjects paired tumor re-biopsy/plasma samples were available; the percent concordance of tissue/plasma was 62.5% for p.T790MEGFR and 37.5% for MUTKRAS. The analysis of time to progression (TTP) and overall survival (OS) in WTKRAS vs. MUTKRAS were not statistically different, even if there was a better survival with WTKRAS vs. MUTKRAS, i.e., TTP 14.4 vs. 11.4 months (p = 0.97) and OS 40.2 vs. 35.0 months (p = 0.56), respectively. CONCLUSIONS: MUTKRAS could be an additional mechanism of escape from EGFR-TKI inhibition and cftDNA is a feasible approach to monitor the molecular development of drug resistance

Role of Low-Molecular-Weight Heparin in Hospitalized Patients with Severe Acute Respiratory Syndrome Coronavirus 2 Pneumonia: A Prospective Observational Study

Background: This study was conducted to evaluate the impact of low-molecular-weight heparin (LMWH) on the outcome of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia. Methods: This is a prospective observational study including consecutive patients with laboratory-confirmed SARS-CoV-2 pneumonia admitted to the University Hospital of Pisa (March 4-April 30, 2020). Demographic, clinical, and outcome data were collected. The primary endpoint was 30-day mortality. The secondary endpoint was a composite of death or severe acute respiratory distress syndrome (ARDS). Low-molecular-weight heparin, hydroxychloroquine, doxycycline, macrolides, antiretrovirals, remdesivir, baricitinib, tocilizumab, and steroids were evaluated as treatment exposures of interest. First, a Cox regression analysis, in which treatments were introduced as time-dependent variables, was performed to evaluate the association of exposures and outcomes. Then, a time-dependent propensity score (PS) was calculated and a PS matching was performed for each treatment variable. Results: Among 315 patients with SARS-CoV-2 pneumonia, 70 (22.2%) died during hospital stay. The composite endpoint was achieved by 114 (36.2%) patients. Overall, 244 (77.5%) patients received LMWH, 238 (75.5%) received hydroxychloroquine, 201 (63.8%) received proteases inhibitors, 150 (47.6%) received doxycycline, 141 (44.8%) received steroids, 42 (13.3%) received macrolides, 40 (12.7%) received baricitinib, 13 (4.1%) received tocilizumab, and 13 (4.1%) received remdesivir. At multivariate analysis, LMWH was associated with a reduced risk of 30-day mortality (hazard ratio [HR], 0.36; 95% confidence interval [CI], 0.21-0.6; P &lt;.001) and composite endpoint (HR, 0.61; 95% CI, 0.39-0.95; P =.029). The PS-matched cohort of 55 couples confirmed the same results for both primary and secondary endpoint. Conclusions: This study suggests that LMWH might reduce the risk of in-hospital mortality and severe ARDS in coronavirus disease 2019. Randomized controlled trials are warranted to confirm these preliminary findings
