In Vivo Functional Evaluation of Tissue-Engineered Vascular Grafts Fabricated Using Human Adipose-Derived Stem Cells from High Cardiovascular Risk Po…
2016
Many preclinical evaluations of autologous small-diameter tissue-engineered vascular grafts (TEVGs) utilize cells from healthy humans or animals. However, these models hold minimal relevance for clinical translation, as the main targeted demographic is patients at high cardiovascular risk such as individuals with diabetes mellitus or the elderly. Stem cells such as adipose-derived mesenchymal stem cells (AD-MSCs) represent a clinically ideal cell type for TEVGs, as these can be easily and plentifully harvested and offer regenerative potential. To understand whether AD-MSCs sourced from diabetic and elderly donors are as effective as those from young nondiabetics (i.e., healthy) in the conte…
Characterization of endometriosis-associated immune cell infiltrates (EMaICI)
2016
Objective: To identify and characterize endometriosis-associated immune cell infiltrates (EMaICI). Furthermore, to define occurrence and size of EMaICI in various types of endometriosis. Methods: Immune cells were characterized in samples of 60 premenopausal women with histological proven endometriosis. Therefore, immunohistochemical staining with monoclonal antibodies for CD3, CD4, CD8, CD45RO, CD25, CD56, CD68, and CD20 on sections of paraffin-embedded endometriotic tissue was performed. Results: EMaICI were observed in all the types of endometriosis, and characterized as T lymphocytes (CD3+), helper T lymphocytes (CD4+), cytotoxic T lymphocytes (CD8+), antigen-experienced T lymphocytes”m…
Solitary Fibrous Tumor of the Vulva: Report of 2 Cases, Including a De Novo Dedifferentiated Solitary Fibrous Tumor Diagnosed After Molecular Demonst…
2018
Solitary fibrous tumor (SFT) is a neoplasm of fibroblastic lineage that has been documented in almost every anatomic location. Vulval SFT is very rare with only 10 cases reported to date. We present 2 additional SFTs located in the vulva, in adult women of 59 and 25 yr of age. The first showed a classic morphology and immunophenotype with uniform and strong STAT6 nuclear expression. The other one was a spindle-cell de novo dedifferentiated SFT with heterogeneous nuclear and cytoplasmic STAT6 staining, which could only be correctly diagnosed after molecular analysis with demonstration of a NAB2-STAT6 gene fusion. This genetic aberration is considered to represent the major pathogenic driver …
Roux-en-Y Gastric Bypass as an Effective Bariatric Revisional Surgery after Restrictive Procedures
2020
<b><i>Introduction:</i></b> Revisional surgery must be considered when insufficient weight loss is attained or weight is subsequently regained. This study aimed to investigate the value of Roux-en-Y gastric bypass (RYGB) as a revisional procedure after restrictive surgery. <b><i>Materials and Methods:</i></b> An observational, retrospective study including patients initially operated on for morbid obesity with restrictive techniques (vertical-banded gastroplasty [VBG], adjustable gastric band [AGB], and sleeve gastrectomy) and reoperated with RYGB in our centre between December 1994 and January 2019. Demographic and anthropometric data, associ…
Polymorphisms in genes involved in T-cell co-stimulation are associated with blood pressure in women.
2019
In recent years, conclusive data have emerged on a relationship between immune system, especially the T-cell, and blood pressure (BP). The objective of the present study was to determine the association between BP and four polymorphisms in CD80, CD86, CD28 and CTLA4 genes that code for key proteins in the T-cell co-stimulation process, in a female cohort. To that end, an association study in a cohort of 934 women over 40 years old from two hospitals was done. Raw data showed a significant association between the SNP rs1129055 of CD86 gene and BP. Analyzing this association against inheritance patterns, higher SBP (p 0.000) and DBP (p = 0.005) values were observed in AA than in GG/GA genoty…
Medroxyprogesterone acetate is a useful alternative to a gonadotropin-releasing hormone antagonist in oocyte donation: a randomized, controlled trial.
2021
Objective To compare ovarian response and reproductive outcomes in oocyte donors undergoing pituitary suppression with medroxyprogesterone acetate (MPA) versus those undergoing conventional treatment with a gonadotropin-releasing hormone (GnRH) antagonist. Design A prospective, randomized, controlled trial of cycles was conducted from October 2017 to June 2019 to evaluate ovarian response in terms of the number of oocytes. The reproductive outcomes of the recipients were retrospectively analyzed later. Setting A university-affiliated private in vitro fertilization center. Patient(s) We randomly divided 318 donors into 2 groups in a 1:1 ratio. The oocytes obtained were assigned to 364 recipi…
Hypomethylating agents in relapsed and refractory AML: outcomes and their predictors in a large international patient cohort.
2018
Although hypomethylating agents (HMAs) are frequently used in the frontline treatment of older acute myeloid leukemia (AML) patients, little is known about their effectiveness in relapsed or primary treatment–refractory (RR)-AML. Using an international multicenter retrospective database, we studied the effectiveness of HMAs in RR-AML and evaluated for predictors of response and overall survival (OS). A total of 655 patients from 12 centers received azacitidine (57%) or decitabine (43%), including 290 refractory (44%) and 365 relapsed (56%) patients. Median age at diagnosis was 65 years. Best response to HMAs was complete remission (CR; 11%) or CR with incomplete count recovery (CRi; 5.3%). …
5-year analysis of neoadjuvant pertuzumab and trastuzumab in patients with locally advanced, inflammatory, or early-stage HER2-positive breast cancer…
2016
Summary Background In the primary analysis of the NeoSphere trial, patients given neoadjuvant pertuzumab, trastuzumab, and docetaxel showed a significantly improved pathological complete response compared with those given trastuzumab and docetaxel after surgery. Here, we report 5-year progression-free survival, disease-free survival, and safety. Methods In this multicentre, open-label, phase 2 randomised trial in hospitals and medical clinics, treatment-naive adults with locally advanced, inflammatory, or early-stage HER2-positive breast cancer were randomly assigned (1:1:1:1) to receive four neoadjuvant cycles of trastuzumab (8 mg/kg loading dose, followed by 6 mg/kg every 3 weeks) plus do…
Observational prospective study on Lactobacillus plantarum P 17630 in the prevention of vaginal infections, during and after systemic antibiotic ther…
2018
We performed a prospective cohort parallel observational study on the use of Lactobacillus plantarum P 17630 in the prevention of vaginal infections. Eligible were women with a diagnosis of bacterial vaginosis (15 days) and documented history of recurrent vaginal infections; and/or cystitis (15 days); and/or treatment with antibiotics for bacterial respiratory tract infections during the week before the study entry. Study subjects were prescribed Lactobacillus plantarum P 17630 100.000.000 UFC one vaginal capsule per day for 6 days, then a capsule per week for 16 weeks. Eligible subjects were enrolled in two parallel cohorts: 85 women using (group A) and 39 not using (group B) Lactobacillu…
The CD68+/H-ferritin+ cells colonize the lymph nodes of the patients with adult onset Still's disease and are associated with increased extracellular…
2015
Summary In this work, we aimed to evaluate the levels of ferritin enriched in H subunits (H-ferritin) and ferritin enriched in L subunits (L-ferritin) and the cells expressing these two molecules in the lymph node (LN) biopsies obtained from adult-onset Still's disease (AOSD) patients, and the possible correlation among these data and the severity of the disease. Ten patients with AOSD underwent LN biopsy. All the samples were stained by immunofluorescence. A statistical analysis was performed to estimate the possible correlation among both H-ferritin and L-ferritin tissue expression and the clinical picture of the disease. Furthermore, the same analysis was performed to evaluate the possib…
