A 5-year multicentre randomized controlled trial comparing personalized, frozen and fresh blastocyst transfer in IVF.
2020
Abstract Research question Does clinical performance of personalized embryo transfer (PET) guided by endometrial receptivity analysis (ERA) differ from frozen embryo transfer (FET) or fresh embryo transfer in infertile patients undergoing IVF? Design Multicentre, open-label randomized controlled trial; 458 patients aged 37 years or younger undergoing IVF with blastocyst transfer at first appointment were randomized to PET guided by ERA, FET or fresh embryo transfer in 16 reproductive clinics. Results Clinical outcomes by intention-to-treat analysis were comparable, but cumulative pregnancy rate was significantly higher in the PET (93.6%) compared with FET (79.7%) (P = 0.0005) and fresh embr…
Endometrija labdabīgo pārmaiņu ķirurģiskās ārstēšanas iespēju salīdzinošā analīze
2018
Endometrija labdabīgās pārmaiņas ir izplatīta patoloģija premenopauzes un postmenopauzes pacientēm, kas tiek ķirurģiski ārstēta. Biežākās endometrija labdabīgās pārmaiņas ir endometrija polipi un endometrija hiperplāzija, šīs pārmaiņas var izpausties asimptomātiski un var radīt simptomus, no kuriem biežākā ir patoloģiska dzemdes asiņošana. Pētījuma mērķis ir atlasīt, analizēt un salīdzināt endometrija hiperplāzijas un endometrija polipu ķirurģiskās ārstēšanas metodes balstoties uz ginekologu pieredzi. Pētījumā atlasīti un analizēti literatūras dati par endometrija polipu un endometrija hiperplāzijas ķirurģiskām ārstēšanas iespējām un intervēti ārsti ginekologi dzemdību speciālisti no Paula …
Endometrija izvērtēšana hormonu receptoru pozitīvām krūts vēža pacientēm, kuras lieto tamoksifēnu
2022
Ievads. Tamoksifēns ir krūts vēža terapijas medikaments. Tas ir selektīvs estrogēnu receptoru antagonists un agonists. Medikamenta lietošana var būt saistīta ar palielinātu risku šādu endometrija patoloģiju attīstībai: endometrija hiperplāzija, endometrija polips, endometrija vēzis un dzemdes mioma. Turklāt pie riska faktoriem endometrija patoloģiju attīstībai pieder arī sievietes vecums krūts vēža diagnozes brīdī, adipozitāte, hormonālās kontracepcijas lietošana, hormonālā aizvietojošā terapija, smēķēšana, blakus saslimšanas, dzemdību un grūtniecību skaits, kā arī endometrija hiperplāzija anamnēzē un endometrija vēzis ģimenē. Mērķis. Atlasīt datus par krūts vēža pacientēm, kuras lieto tamo…
Perfil de miRNAs secretados en el fluido endometrial a lo largo del ciclo menstrual. Caracterización funcional. Potencial uso como herramienta diagnó…
2014
INTRODUCCION La implantación embrionaria y el embarazo requieren una comunicación entre el endometrio y el embrión pre-implantatorio. El endometrio humano posee dos funciones principales: la adquisición temporal de un fenotipo adhesivo que favorezca la implantación embrionaria, también denominada “receptividad endometrial”, y una vez se produce implantación, ejerce un segundo papel en la invasión, placentación, desarrollo fetal y finalmente el parto. Para ello, el endometrio dialoga de forma activa con el embrión mediante mecanismos de señalización que pueden ser secretados de forma paracrina hacia el fluido endometrial que nutren y regulan el correcto desarrollo embrionario. Actualmente, n…
Diagnosi e trattamento endoscopico dell'endometriosi vescicale
2007
L’endometriosi coinvolge l’apparato urinario in circa 1-2% dei casi e la sede più frequentemente colpita e la vescica. Obiettivo del nostro studio e la valutazione dell’efficacia e della sicurezza del trattamento laparoscopico in corso di endometriosi vescicole, attraverso l’analisi degli aspetti clinici prima e dopo l’intervento. Dal Giugno 2005 al Gennaio 2007, abbiamo trattato mediante chirurgia laparoscopica otto donne affette da endometriosi vescicale. In tre pazienti la lesione interessava ilde-trusore a tutto spessore ed è stata necessaria una cistectomla parziale; negli altri cinque casi il nodulo endometriosico era più superficiale ed e stata sufficiente una resezione extramucoca …
Endometriosis and strategies of fertility preservation: a systematic review of the literature.
2019
Endometriosis is a common chronic inflammatory disorder, often causing both pain and infertility. It is estimated that 25-50 % of patients undergoing fertility treatments have had endometriosis as it involves an impairment of the ovarian reserve. For these reasons, endometriosis has been highlighted as a condition that may require a fertility preservation procedure, while being benign in nature. The aim of this review is to summarize the current evidence on fertility preservation techniques for patients affected by endometriosis, focusing on the main characteristics of the different approaches. A systematic review of literature was performed by searching in the main electronic databases (ME…
Effects of Ga3 and Ca2+ on barley aleurone protoplasts: a freeze-fracture study
1988
Freeze-fracture electron microscopy was used to study changes in the endomembrane system of barley (Hordeum vulgare L. cv. Himalaya) aleurone protoplasts. Protoplasts were used for this study because their response to calcium and the plant hormone gibberellic acid (Ga3) can be monitored prior to rapid freezing of cells for electron microscopy. Protoplasts incubated in Ga3 plus Ca2+ secrete elevated levels of a-amylase relative to cells incubated in Ga3 or Ca2+ alone. The endoplasmic reticulum (ER) and Golgi apparatus of protoplasts incubated in Ga3 plus Ca2+ undergo changes that are well correlated with the synthesis and secretion of a-amylase. The ER, which appears as short, single sheets …
One center experience of pneumatosis cystoides intestinalis
2017
Introduction Pneumatosis cystoides intestinalis (PCI) is a rare benign condition, in which gas is found in a linear or cystic form in the subserosa or submucosa. The subserous cysts are most frequently found in the small bowel while the submucous localizations are predominantly seen in the colonic wall. Peritoneal pneumatosis, abdominal gas cysts, cystic lymphopneumatosis, intestinal emphysema or intestinal gas cysts are terms used to describe the occurrence of multiple, gas-filled cysts, of the gastrointestinal tract. Incidence of PCI was reported to be 0.03% in the general population. It is a radiographic finding and not a diagnosis, as the etiology varies from benign conditions to fulmin…
Expression Profile of Endoglin in Different Grades of Endometrial Cancer
2019
Background Endoglin is a marker of active, proliferating endothelial cells of blood vessels. In many cancers, it is present in both peripheral vessels and vessels located inside the tumor. Endoglin is more specific and sensitive compared to other tumor angiogenesis markers. It is suggested that endoglin can be considered a reliable marker of disease outcome. Objective The aim of the study was to assess the expression of endoglin and to determine its potential usefulness as a complementary molecular marker of endometrial cancer. Method The study included 60 women who underwent hysterectomy: 45 with endometrioid endometrial cancer (study group) and 15 without neoplastic changes (control group…
Air quality and relative humidity in commercial aircrafts: an experimental investigation on short-haul domestic flights
2013
Abstract Nowadays the achievement of a comfortable environment in aircraft cabins is a factor of paramount importance in air travel business competition; on the other hand, the need of reducing the propulsion fuel cost has driven the airline companies to adopt air handling systems that may reduce the levels of thermal comfort and air quality inside the cabins of commercial airliners. With the aim of contributing to a better knowledge of this matter, this paper reports the results of an experimental study upon the indoor air quality aboard commercial aircrafts for 14 domestic flights less than 1 h and half long. The parameters monitored were temperature, relative humidity and carbon dioxide …
