Migration and fdi: the role of job skills
2018
Abstract Using a multi-country gravity framework, this paper models and quantifies the relevance of migrants' job position in fostering Foreign Direct Investment (FDI). High-skilled migrants are defined as those individuals born in the investors' home/host country occupying managerial or professional positions in the host/home country of investment. Our estimates show that higher shares of migrants with management skills in a given country promote FDI into that country. In contrast, an increase in the share of migrants in non-qualified positions (regardless of their educational attainment) has a negative impact on FDI decisions. These findings highlight that the FDI-enhancing effect of migr…
Dalle Cronache del mal d’amore al ciclo dell’Amica geniale: continuità ed evoluzione nella narrativa di Elena Ferrante
2019
The paper analyzes the whole narrative production of Elena Ferrante, emphasizing its unity and cohesion. Cohesion coexists with discontinuity: the publication of My Brilliant Friend marks an inventive turning point and reveals new strategies. But it’s even remarkable Ferrante’s predilection for a narrative in which «the flow of storytelling that despite its density manages to sweep you away».
Homeward Bound FDI: Are Migrants a Bridge over Trouble Finance?
2016
Migrants can lower cross-border investment barriers, help investors by providing information about their homeland and reduce transaction costs by sharing expertise on regulations, customs and procedures. In addition to generating these well-known networking effects, migrants can also provide valuable information about local finance, thereby easing the credit constraints foreign investors faced during the 2007 financial crisis. This paper sheds new light on the underlying mechanisms through which migration may affect foreign investment in the migrant's homeland by distinguishing between the effects on FDI's intensive and extensive margins. Gravity estimates for 140 countries for the period 2…
Impact of resection margin status and revision transoral laser microsurgery in early glottic cancer: analysis of organ preservation and local disease…
2022
Abstract Introduction Transoral laser microsurgery represents the treatment of choice for early glottic cancer. Its use and effectiveness are mainly related to laryngeal exposure and deep extension of tumor. Histopathologic assessment of surgical margin presents a main issue about transoral laser microsurgery and complete oncological excision. Objective The aim was to analyze the impact of revision surgery on organ preservation and local disease control in patients with early glottic cancer treated by transoral laser microsurgery. Methods We carried out a retrospective study on a cohort of 153 patients with early glottic cancer (Tis, T1, T2) treated by transoral laser microsurgery. Resectio…
An international multicentre prospective audit of elective rectal cancer surgery; operative approach versus outcome, including transanal total mesore…
2018
Introduction: Transanal total mesorectal excision (TaTME) has rapidly emerged as a novel approach for rectal cancer surgery. Safety profiles are still emerging and more comparative data is urgently needed. This study aimed to compare indications and short-term outcomes of TaTME, open, laparoscopic, and robotic TME internationally. Methods: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 audit was performed. Patients undergoing elective total mesorectal excision (TME) for malignancy between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary outcome measure was anastomotic leak. Results: Of 2579 included patients, 76.2% (1966/257…
Accuracy of CT and MRI to assess resection margins in primary malignant bone tumours having histology as the reference standard.
2018
AIM To evaluate the accuracy of magnetic resonance imaging (MRI) and computed tomography (CT) in assessing the resection margins of primary malignant bone tumours. MATERIALS AND METHODS Resected primary malignant bone tumour specimens removed from 46 patients (27 male; mean age: 48±22 years) were imaged using MRI (fat-saturated proton density-weighted and three-dimensional fat-suppressed T1-weighted gradient-recalled-echo) and CT immediately after surgery. A radiologist and an orthopaedist evaluated bone and soft-tissue margins of the specimens on both examinations. Histological evaluation was performed by a senior orthopaedic oncology pathologist. Margins were classified as R0 (safe margin…
Predicting positive surgical margins in partial nephrectomy: A prospective multicentre observational study (the RECORd 2 project)
2020
PURPOSE: to evaluate clinical predictors of positive surgical margins (PSMs) in a large multicenter prospective observational study and to develop a clinic nomogram to predict the likelihood of PSMs after partial nephrectomy (PN). MATERIALS AND METHODS: We prospectively evaluated 4308 patients who had surgical treatment for renal tumors between January 2013 and December 2016 at 26 urological Italian Centers (RECORd 2 project). Two multivariable logistic models were evaluated to predict the likelihood of PSMs. Center caseload was dichotomized using a visual assessment adjusted for several predictors of PSMs. A nomogram predicting PSMs was developed. RESULTS: Overall, 2076 patients treated wi…
Trends and outcome of neoadjuvant treatment for rectal cancer: A retrospective analysis and critical assessment of a 10-year prospective national reg…
2021
Introduction: Preoperative treatment and adequate surgery increase local control in rectal cancer. However, modalities and indications for neoadjuvant treatment may be controversial. Aim of this study was to assess the trends of preoperative treatment and outcomes in patients with rectal cancer included in the Rectal Cancer Registry of the Spanish Associations of Surgeons. Method: This is a STROBE-compliant retrospective analysis of a prospective database. All patients operated on with curative intention included in the Rectal Cancer Registry were included. Analyses were performed to compare the use of neoadjuvant/adjuvant treatment in three timeframes: I)2006–2009; II)2010–2013; III)2014–2…
Prognostic Impact of Frozen Section Investigation and Extent of Proximal Safety Margin in Gastric Cancer Resection
2020
Background and aims Guidelines propose different extents of macroscopic proximal margin for gastric cancer and frozen margin investigation in selected cases, but data is lacking. This study was to evaluate the necessary extent of macroscopic proximal margin, accuracy of frozen margin investigation, and prognostic impact of tumor-free proximal margin length in pT2-pT4 gastric cancer. Study design Proximal and distal frozen margins were routinely investigated intraoperatively in all pT2-pT4 gastric cancers resected between 2011 and 2017. Macroscopic and microscopic proximal margin lengths were correlated. For R0-resections, survival analysis was performed for distal gastrectomy (DG) with micr…
Oncologic outcome and continence recovery after laparoscopic radical prostatectomy: 3 years' follow-up in a "second generation center".
2006
Objectiues: Laparoscopic radical prostatectomy in major centers guarantees oncologic and functional results equal to open procedures. In our institution this operation was introduced in 2001 after an adequate training in laparoscopic surgery. We report the oncologic and functional results after 3 years of experience.Methods: We considered our first 150 patients that had undergone transperitoneal laparoscopic radical prostatectomy. The following parameters were prospectively collected and analyzed: pathological findings, surgical margins, surgical time, blood loss, hospital stay, catheterization, complications, oncologic follow-up and continence.Results: Single positive surgical margins were…
