Stem cell-secreted factor therapy regenerates the ovarian niche and rescues follicles.

2021

Background Ovarian senescence is a normal age-associated phenomenon, but increasingly younger women are affected by diminished ovarian reserves or premature ovarian insufficiency. There is an urgent need for developing therapies to improve ovarian function in these patients. In this context, previous studies suggest that stem cell–secreted factors could have regenerative properties in the ovaries. Objective This study aimed to test the ability of various human plasma sources, enriched in stem cell–secreted factors, and the mechanisms behind their regenerative properties, to repair ovarian damage and to promote follicular development. Study Design In the first phase, the effects of human pla…

Orthopedic-orthodontic treatment of the patient with Turner's syndrome: Review of the literature and case report.

2018

Aims Turner syndrome (TS) patients have phenotypical variable presentations and they are more susceptible to endocrine, auto-immune, and structural anomalies. Typical clinical characteristics are short stature and premature ovarian insufficiency. Patients with TS show a typical cranial-facial morphology with bi-maxillary bi-retrusion, high-arched palate, micrognathia, and class II malocclusion. Aim of our study is to present the orthopedic-orthodontic treatment approach of a young TS patient and data of stability after 7 years. Methods and results A careful analysis of anamnestic data was performed. After extraoral and intraoral examination, cephalometric measurements and examination of mod…

EMAS position statement: Predictors of premature and early natural menopause.

2019

Simoncini, Tommaso/0000-0002-2971-0079; Chung, Hsin-Fang/0000-0003-3261-5942; Mishra, Gita/0000-0001-9610-5904 WOS:000468709100014 PubMed ID: 31027683 Introduction: While the associations of genetic, reproductive and environmental factors with the timing of natural menopause have been extensively investigated, few epidemiological studies have specifically examined their association with premature (< 40 years) or early natural menopause (40-45 years). Aim: The aim of this position statement is to provide evidence on the predictors of premature and early natural menopause, as well as recommendations for the management of premature and early menopause and future research. Materials and methods…

Trasplante autólogo de médula ósea en ovario en mujeres con baja reserva ovárica y fallo ovárico precoz, para rejuvenecimiento del nicho ovárico y fa…

2020

Como consecuencia del retraso de la maternidad a causa de las tendencias sociales actuales, existe una disminución de la calidad y cantidad de ovocitos disponibles. Al problema fisiológico de la edad materna avanzada, se suman dos patologías, que asocian una baja reserva ovárica, en pacientes jóvenes: baja respuesta ovárica (del inglés, poor ovarian response, o POR), e insuficiencia ovárica prematura(del inglés, premature ovarian insufficiency o POI). Numerosos protocolos de estimulación ovárica han sido desarrollados, sin ser efectivos, siendo en la mayoría de los casos, la única opción para estas pacientes la donación de ovocitos/embriones. Varios trabajos de investigación han descrito la…
