Safety and efficacy of non-steroidal anti-inflammatory drugs to reduce ileus after colorectal surgery

2019

Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery.A prospective multicentre cohort study was delivered by an international, student- and trainee-led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a c…

Le valutazioni di bilancio nella prospettiva della tradizione giuridica e dottrinale italiana

2018

Il capitolo si inserisce quale introduzione storiografica al tema oggetto di una monografia open source patrocinata dalla Sidrea (Società Italiana di Ragioneria ed Economia Aziendale). Detta monografia è il frutto di una ricerca collettanea sulla riforma del bilancio civilistico ex DPR 139/2015. I singoli contributi della stessa riguardano infatti le singole aree del bilancio. Rispetto a questa complessiva ricerca della società accademica di settore, il saggio/capitolo in oggetto, a natura esplicitamente introduttiva, intende mostrare come la disciplina giuridica sia sempre stata influenzata da un dibattito dottrinale a monte di tipo economico-aziendale, questo in Italia particolarmente ric…

From Cash to Accrual Accounting: The seminal case of the Sicilian Regional Public Bodies

2019

The Italian public sector has been traditionally characterised by a cash-based and compliance-oriented governmental accounting, principally aimed at supporting the budgetary control by the legislative body. Over the last few decades, however, a new movement has been spreading around the world, casting doubt on the potentialities and advantages of the traditional accounting system in favour of an accrual basis one. This paper traces the progressive introduction of a complete accrual accounting by the Sicilian Regional public bodies – within the context of international and national public management changes – pursuing the ultimate goal to improve efficiency, accountability and transparency. …

The Concept of Value for CSR: A Debate Drawn from Italian Classical Accounting

2018

This paper underlines the importance of the concept of value for corporate social responsibility (CSR) and then explores it beyond economics, looking for its social and philosophical roots. Con- sidering the most recent literature on the matter, the dilemma between a non monetary, multi variable conception and a monetary, one variable conception is set. To obtain the origins of the meaning for this basic concept in CSR, Italian literature regarding ‘value in accounting’ is ex- plored. The main result from this first survey is the existence of a ‘chain’ from the highest con- ception of value (philosophical, ethical), to the most practical conception (accounting techniques of measurement). By…

Safety of hospital discharge before return of bowel function after elective colorectal surgery

2020

Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multiva…

Effect of COVID-19 pandemic lockdowns on planned cancer surgery for 15 tumour types in 61 countries: an international, prospective, cohort study

2021

This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index 60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models wer…

Elective Cancer Surgery in COVID-19-Free Surgical Pathways during the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study

2020

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a …

W pair production cross-section and W branching fractions in $e^{+}e^{-}$ interactions at 189 GeV

2000

The cross-section for the process e+e- -> W+W- has been measured with the data sample collected by DELPHI at an average centre-of-mass energy of 189 GeV and corresponding to an integrated luminosity of 155 pb^{-1}. Based on the 2392 events selected as WW candidates, the cross-section for the doubly resonant process e+e- -> W+W- has been measured to be 15.83 +- 0.38 (stat) +- 0.20 (syst) pb. The branching fractions of the W decay were also measured and found to be in good agreement with the Standard Model expectation. From these a value of the CKM mixing matrix element |V_{cs}| = 1.001 +- 0.040 (stat) +- 0.020 (syst) was derived.

Delaying surgery for patients with a previous SARS-CoV-2 infection

2020

With at least 28 elective million operations delayed during the first three months of the COVID-19 pandemic, the number of patients who will require surgery after a previous SARS-CoV-2 infection is likely to increase rapidly1. Operating on patients with an active perioperative SARS-CoV-2 infection is now known to carry a very high pulmonary complication and mortality rate2. Urgent information is needed to guide whether postponing surgery in patients with a previous SARS-CoV-2 infection leads to a clinical benefit, and the optimal length of delay.

Update of the search for supersymmetric particles in scenarios with Gravitino LSP and Sleptons NLSP

2001

An update of the search for sleptons, neutralinos and charginos in the context of scenarios where the lightest supersymmetric particle is the gravitino and the next-to-lightest supersymmetric particle is a slepton, is presented, together with the update of the search for heavy stable charged particles in light gravitino scenarios and Minimal Supersymmetric Standard Models. Data collected in 1999 with the DELPHI detector at centre-of-mass energies around 192, 196, 200 and 202 GeV were analysed. No evidence for the production of these supersymmetric particles was found. Hence, new mass limits were derived at 95% confidence level.

I Conti del Teatro Massimo. Contesto economico-politico e Analisi dei flussi finanziari

2018

L’Italia è universalmente considerata il “Paese dell’Arte” per definizione. Con un patrimonio storico incalcolabile, una concentrazione di beni culturali e fenomeni storici unici al mondo quali il Rinascimento, non sembra oggi possibile costruire una storia universale dell’arte senza passare in qualche modo dall’Italia. Gli studi sulla storia dell’arte sinora hanno privilegiato l’aspetto puramente estetico della storia stessa, o – quando si è voluto prendere in considerazione il contesto istituzionale di riferimento – questo ha riguardato solamente o in gran parte il contesto politico, relativo ad esempio al mecenatismo, ovvero quello antropologico, cioè dei fermenti culturali, filosofici, …

Search for the Standard Model Higgs boson at LEP in the year 2000

2001

Searches for the Standard Model Higgs boson have been performed in the data collected by the DELPHI experiment at LEP in the year 2000 at centre-of-mass energies between 200 and 209 GeV corresponding to a total integrated luminosity of 224 pb^{-1}. No evidence for a Higgs signal is observed in the kinematically accessible mass range, and a 95% CL lower mass limit of 114.3 GeV/c^2 is set, to be compared with an expected median limit of 113.5 GeV/c^2 for these data.

Porphyrin tributyltin(IV) complexes for a novel approach in the tratment of human melanoma

2012

Melanoma is the most deadly form of skin cancer, largely refractory to existing therapies. The study of porphyrin derivatives as potential anti-tumor drugs has been an interesting field of investigation in the last years. Recently, a photo-independent cytotoxic effect of (Bu3Sn)4TPPS in the blocking melanoma cell proliferation an inducing a morphology cell change was investigated.[1] Amphiphilic CD (ACyD) provides more water soluble and adaptable nanovectors through modulation of the balance between hydrophobic and hydrophilic chains at both CD sides. ACyD can be conveniently tailored by covalently appending fluorescent label or receptor-targeting glycosyl- groups and can encapsulate conven…

Measurement of the ZZ cross-section in e(+)e(-) interactions at 183-189 GeV

2001

Measurements of on-shell ZZ production are described, using data collected by DELPHI in 1997 and 1998, at centre-of-mass energies sqrt(s) = 182.6 GeV and 188.6 GeV respectively. Results obtained in each of the final states q qbar q qbar, mu+mu- q qbar, e+e- q qbar, nu nubar q qbar, l+l-l+l-, and nu nubar l+l- are presented. The measured cross-sections for on-shell ZZ production via the tree-level doubly-resonant graphs (NC02) are: sigma_{NC02}(182.6 GeV) = 0.38 +- 0.18 (stat) +- 0.04 (syst) pb, sigma_{NC02}(188.6 GeV) = 0.60 +- 0.13 (stat) +- 0.07 (syst) pb. They are consistent with the Standard Model expectations of 0.25 pb and 0.65 pb at each energy.

Measurement of the semileptonic b branching fractions and average b mixing parameter in Z decays

2001

The semileptonic branching fractions for primary and cascade b decays BR(b -> lepton-), BR(b -> c -> lepton+) and BR(b -> cbar -> lepton-) were measured in hadronic Z decays collected by the DELPHI experiment at LEP. The sample was enriched in b decays using the lifetime information and various techniques were used to separate leptons from direct or cascade b decays. By fitting the momentum spectra of di-leptons in opposite jets, the average b mixing parameter chi-bar was also extracted. The following results have been obtained: BR(b -> lepton-) = (10.70 +/- 0.08 (stat) +/- 0.21 (syst)_{+0.44}^{-0.30}(model))% BR(b -> c -> lepton+) = (7.98 +/- 0.22 (stat) +/- 0.21 (s…

Measurement and Interpretation of Fermion-Pair Production at LEP Energies of 183 and 189 GeV

2000

An analysis of the data collected in 1997 and 1998 with the DELPHI detector at e+e- collision energies close to 183 and 189 GeV was performed in order to extract the hadronic and leptonic fermion-pair cross-sections, as well as the leptonic forward-backward asymmetries and angular distributions. The data are used to put limit on contact interactions between fermions, the exchange of R-parity violating SUSY sneutrinos, Z' bosons and the existence of gravity in extra dimensions.
