Minimally invasive interval debulking surgery in ovarian neoplasm (MISSION trial–NCT02324595): a feasibility study

2016

Background Laparoscopy has acquired an increasing role in the management of ovarian cancer. Laparoscopic cytoreduction could represent a new frontier for selected patients after neoadjuvant chemotherapy (NACT). Objective We sought to assess feasibility and early complication rate of minimally invasive (MI) interval debulking surgery (IDS) in stage III-IV epithelial ovarian cancer (EOC) patients after NACT. Study Design This is a phase II multicentric study in advanced EOC cases with clinical complete response after NACT, according to Gynecologic Cancer Intergroup and Response Evaluation Criteria In Solid Tumors criteria. Institutional review board approval was obtained and all patients sign…

Safety of a 3-weekly schedule of carboplatin plus pegylated liposomal doxorubicin as first line chemotherapy in patients with ovarian cancer: prelimi…

2006

Abstract Background The MITO-2 (Multicentre Italian Trials in Ovarian cancer) study is a randomized phase III trial comparing carboplatin plus paclitaxel to carboplatin plus pegylated liposomal doxorubicin in first-line chemotherapy of patients with ovarian cancer. Due to the paucity of published phase I data on the 3-weekly experimental schedule used, an early safety analysis was planned. Methods Patients with ovarian cancer (stage Ic-IV), aged 2, every 3 weeks or to carboplatin AUC 5 plus pegylated liposomal doxorubicin 30 mg/m2, every 3 weeks. Treatment was planned for 6 cycles. Toxicity was coded according to the NCI-CTC version 2.0. Results The pre-planned safety analysis was performed…

Kavapyrone enriched extract fromPiper methysticum as modulator of the GABA binding site in different regions of rat brain

1994

Regional differences in the modulation of [3H] muscimol binding to GABAA receptor complexes by kavapyrones, compounds of the rhizome of the plant Piper methysticum which possess sedative activity, were demonstrated using membrane fractions obtained from target brain centers of kavapyrone action: hippocampus (HIP), amygdala (AMY) and medulla oblongata (MED), and from brain centers outside the main kavapyrone effects as frontal cortex (FC) and cerebellum (CER). The kava extract enhanced the binding of [3H] muscimol in a concentration-dependent manner with maximal potentiation of 358% over control in HIP followed by AMY and MED (main target brain centers). Minimal stimulation was observed in C…

Effect of antiangiogenic treatment on peritoneal endometriosis-associated nerve fibers

2012

Objective To investigate the effect of antiangiogenic treatment on experimental endometriotic lesion nerve fibers. Design Heterologous mouse model of endometriosis. Setting University Institute IVI, University Hospital La Fe. Animal(s) Ovariectomized nude mice (n = 16) receiving human endometrial fragments from oocyte donors (n = 4). Intervention(s) Endometrium fragments stuck in the peritoneum of 5-week-old female nude mice treated with vehicle (n = 8) and antiangiogenic agent cabergoline (n = 8; Cb 2, 0.05 mg/kg/day) for 14 days. Main Outcome Measure(s) Immunofluorescence analysis of von-Willebrand factor (vWF) and vascular smooth muscle cells (αSMA) for evaluating the number of immature …

A simplified method to quantitate atherosclerosis in the rabbit aorta.

2001

A simple method to quantitatively evaluate atherosclerosis in the rabbit aorta by measuring macroscopic lesion areas (%) was attempted in the present study. Ten female New Zealand white rabbits were fed on a cholesterol-rich diet (5/1000 g of food) during 4 months. Five of them were oophorectomized at the beginning and all were sacrificed at the end. Total levels of cholesterol increased from 50.7+/-14.7 mg/dl to 782.8+/-296.0. No significant differences were observed between oophorectomized and intact rabbits. At 4 months, the cholesterol-rich diet caused in both, intact and oophorectomized rabbits, atherosclerotic lesions affecting 17 and 46% of the aortic surface, respectively. This meth…

Evaluation of the potential therapeutic effects of a double-stranded RNA mimic complexed with polycations in an experimental mouse model of endometri…

2015

Objective To assess the therapeutic potential of polyinosine-polycytidylic acid, a double-stranded RNA molecule with selective proapoptotic and antiangiogenic activity, complexed with polyethyleneimine (pIC PEI ) in treating endometriosis. Design A heterologous mouse model of endometriosis was created by injecting human endometrial fragments into the peritoneum. Endometrial fragments were engineered to express the fluorescent protein mCherry as a reporter to monitor status over the course of the 4-week study. Setting University-affiliated infertility center. Animal(s) Ovariectomized and hormone-replaced nude mice (n = 30) injected with fluorescent-labeled human endometrial fragments at 4–6 …

Gathering of aging and estrogen withdrawal in vascular dysfunction of senescent accelerated mice.

2010

The aim of this work was to characterize a mouse model of experimental menopause and cardiovascular aging that closely reflects menopause in women. Senescence accelerated mouse (SAM)-Resistant type 1 (SAMR1, n=30) and SAM-Prone type 8 (SAMP8, n=30) were separated at 5months of age into three groups: 1) sham-operated (Sham); 2) ovariectomized (Ovx); and 3) ovariectomized chronically-treated with estrogen (Ovx+E2). Contractile responses to KCl (60mM) and thromboxane A(2) were greater in aorta from SAMP8 mice compared with SAMR1 in all groups. Neither ovariectomy nor estrogen replacement modified the contractile responses from SAMR1 mice. Conversely, in Ovx SAMP8 the increased maximal contract…

Efficacy of Low-Dose Paroxetine for the Treatment of Hot Flushes in Surgical and Physiological Postmenopausal Women: Systematic Review and Meta-Analy…

2019

Background and Objectives: Hot flushes and sleep disturbances are the most common vasomotor symptoms (VMS) reported by postmenopausal women. Hormonal treatment is to date referred to as the gold standard approach but not suitable for all the patients. Alternative treatments are needed in case of a contraindication to menopausal hormone therapy (MHT), adverse side effects, and poor compliance. Paroxetine salt is the only nonhormonal medication approved by the US Food and Drug Administration for the management of VMS. Nonetheless, few trials with low consensus are available about this topic. In this review, we aimed to evaluate the efficacy of low-dose paroxetine therapy in the treatment of v…
