The association between intrapartum opioid fentanyl and early breastfeeding: A prospective observational study
2021
Introduction: Intrapartum opioids in labor may interfere with the early breastfeeding phase and cause breastfeeding difficulties. This study examines the effects of intrapartum fentanyl given intravenously (IV) or through epidural analgesia (EDA) on early breastfeeding. Material and methods: This is a prospective observational study conducted in a regional maternity unit. We included 1101 healthy mothers of term singleton babies in vertex presentation born between 2016 and 2018 (468 nulliparous and 633 multiparous). The main data were collected prospectively, and additional data were retrieved from hospital records. The main outcome measures were exclusive breastfeeding at discharge, sponta…
Feasibility and safety of two different surgical routes for the eradication of recto-vaginal endometriosis with vaginal mucosa infiltration (Endo-Vag…
2020
Introduction: Recto-vaginal endometriosis surgical management needing partial colpectomy is a surgically challenging condition and has been associated with a notable risk of major postoperative complications. In the present study we sought to compare feasibility and safety of total laparoscopic (TL) and vaginal-assisted (VA) routes in women affected by symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration scheduled for minimally invasive surgery. Material and methods: Multi-centric, retrospective cohort study on medical records of consecutive reproductive age women submitted to complete macroscopic eradication of symptomatic recto-vaginal endometriosis with vaginal mucosa…
Unruptured tubal pregnancy: local low-dose therapy with methotrexate under transvaginal ultrasonographic guidance.
1996
Thirty patients with unruptured ectopic pregnancy (4-10 weeks' gestation) were treated locally with methotrexate (MTX) under sonographic guidance. The transvaginal puncture was performed under analgesic sedation using an automatic puncturing device. Local MTX therapy was successful in 25 patients (83.3%). Eighteen of these patients had received a single MTX instillation with a total dose of 10 mg, 7 patients had received a second instillation with 10 mg because of plateauing hCG levels after the first instillation. In 5 patients MTX therapy was unsuccessful. Surgical intervention was necessary within 4 h to 15 days after MTX treatment, due to severe tubal bleeding (n = 1) or the development…
Aspetti tipo-cronologici e archeometrici delle ceramiche africane nel territorio di Cignana (Naro, AG, Sicilia)
2020
Il progetto di ricerca, condotto in cotutela tra l'Università di Palermo e Aix-Marseille Université, si basa sullo studio delle ceramiche africane importate in Sicilia tra la fine del I e il VII secolo d.C.. La ricerca si basa sui frammenti - tutte le classi incluse - raccolti dal gruppo di ricerca di Palermo durante le ricognizioni archeologiche nei dintorni della villa romana di Cignana (Agrigento) e nell'entroterra di Termini Imerese (Palermo). L'approccio multidisciplinare archeologico ed archeometrico, condotto in collaborazione con diversi specialisti di queste discipline, ha permesso di definire l'origine delle diverse produzioni e di riflettere sulla loro circolazione in Sicilia, in…
Core-shell Zn-doped TiO2-ZnO nanofibers fabricated via a combination of electrospinning and metal-organic chemical vapour deposition
2010
Zn-doped TiO2 nanofibers shelled with ZnO hierarchical nanoarchitectures have been fabricated combining electrospinning of TiO2 (anatase) nanofibers and metal-organic chemical vapor deposition (MOCVD) of ZnO. The proposed hybrid approach has proven suitable for tailoring both the morphology of the ZnO external shell as well as the crystal structure of the Zn-doped TiO2 core. It has been found that the Zn dopant is incorporated in calcined electrospun nanofibers without any evidence of ZnO aggregates. Effects of different Zn doping levels of Zn-doped TiO2 fibers have been scrutinized and morphological, structural, physico-chemical and optical properties evaluated before and after the hierarc…

A comparison of two different formulations for Arc Routing Problems on Mixed graphs
2006
[EN] Arc routing problems on mixed graphs have been modelled in the literature either using just one variable per edge or associating to each edge two variables, each one representing its traversal in the corresponding direction. In this paper, and using the mixed general routing problem as an example, we compare theoretical and computationally both formulations as well as the lower bounds obtained from them using Linear Programming based methods. Extensive computational experiments, including some big and newly generated random instances, are presented.
Toxicity of the antimalarial artemisinin and its dervatives.
2010
As long as no effective malaria vaccine is available, chemotherapy belongs to the most important weapons fighting malaria. One of the most promising new drug developments is the sesquiterpene artemisinin (ARS) and its derivatives, e.g., artemether, arteether, and sodium artesunate. Large clinical studies and meta-analyses did not show serious side effects, although proper monitoring of adverse effects in developing countries might not be a trivial task. There is a paucity of large-scale clinical trials suitable to detect rare but significant toxicity. Therefore, a final and definitive statement on the safety of artemisinins still cannot be made. In contrast, animal experiments show consider…
Individual repeatability in timing and spatial flexibility of migration routes of trans-Saharan migratory raptors
2015
Satellite-tracking technology has allowed scientists to make a quantum leap in the field of migration ecology. Nowadays, the basic description of migratory routes of many species of birds has been reported. However, the investigation of bird migration at individual level (i.e. repeatability in migratory routes and timing) still remains seldom explored. Here, we investigated repeated migratory trips of a trans-Saharan endangered migratory raptor, the Egyptian Vulture Neophron percnopterus, tracked by GPS satellite telemetry. We compared between- and within-individual variation in migratory routes and timing in order to assess the degree of repeatability (or conversely, the flexibility) in mi…
Retrograde transport of sodium selenite and intracellular injection of micro-ruby: a combined method to describe the morphology of zinc-rich neurones.
2003
Abstract Zinc is found in synaptic vesicles in a large number of glutamatergic systems. Its involvement in neurotransmission and neurological disorders has been suggested. There are methods for tracing these circuits, but they do not fill the dendritic tree. In this study, extracellular selenite injections in vivo were combined with intracellular injection of fluorochromes in fixed tissue to reveal the morphology of these zinc-rich neurones. Intraperitoneal and intracerebral injections of sodium selenite alone or intracerebral injections of selenite combined with bisbenzimide were made in the visual cortex of the rat in order to locate the somata of zinc-rich neurones. After 24 h of retrogr…
