There is a lack of agreement among fertility specialists with regard to the routine use of mock embryo transfer (MET) before each in vitro fertilization (IVF) treatment cycle. While MET may be beneficial with previous difficult embryo transfer cases, its routine use before first IVF cycle has not been evaluated.

To find out the effect of MET before the first IVF cycle on clinical pregnancy rate.

This is a single-centre randomized controlled trial with a balanced randomization (11), carried out between November 2015 and October 2017, with 200 subjects at Homerton university hospital, London, randomized into either MET or control. The primary outcome was clinical pregnancy rate (detection of heart activity on the ultrasound scan), the secondary outcome measures were live birth rate, miscarriage and multiple pregnancy rates, difficult ETs, rate of blood or mucus on the catheter tip.

No significant differences were observed in the baseline or cycle characteristics between the two groups. The clinical pregnancy rate was similar between the MET and control groups based on both intension to treat and per protocol analyses (p = 0.98, p = 0.92, respectively). Additionally, no significant difference was seen in the live birth rate in both groups on intension to treat and per protocol analyses (p = 0.67, p = 0.47), respectively.

Our study concludes that MET prior to first IVF cycle may not improve the success rate in young women without risk factors for a difficult embryo transfer.

Human endometrium with consecutive regeneration capability undergoes monthly hormonal changes for probable implantation, which confirms the presence of the cells in the basalis layer known as stem cell.

Previously, we reported the isolation and culture of the mesenchymal-like cells from human endometrium. In this study, we evaluated the biological and stemness characteristics of these cells.

The characterization of Yazd human endometrial-derived mesenchymal stem/stromal cells (YhEnMSCs) was assessed using immunofluorescence (IF) staining for CD105, VIMENTIN, and FIBRONECTIN as markers and RT-PCR for

, and
genes. LY3200882 Flow cytometry (FACS) was performed for CD44, CD73, CD90, and CD105 markers. Moreover, the differentiation capacity of the YhEnMSCs to the osteoblast and adipocytes was confirmed by Alizarin Red and Oil Red staining.

YhEnMSCs expressed CD105, VIMENTIN, FIBRONECTIN, CD44, CD73, and CD90 markers and

Our data confirm previous reports by other groups indicating the application of endometrial cells as an available source of MSCs with self-renewal and differentiation capacity. Accordingly, YhEnMSCs can be used as a suitable source for cell-based therapies.

Endometrioma is a common high-recurrence gynecological disease that affects infertility. Surgical resection using laparotomy or laparoscopy is applied as a standard treatment. Moreover, sclerotherapy is reported to be effective as a non-invasive method for treating endometrioma.

To evaluate whether the ethanol retention or aspiration after sclerotherapy improve pregnancy outcome in infertile women with endometrioma.

In a retrospective study, hospital records of 43 women with recurrent or bilateral endometrioma who had been undergone transvaginal ultrasound sclerotherapy were reviewed. They were selected to receive either ethanol for 10 min, ethanol injection, irrigation, and then aspiration or total retention without aspiration based on the surgeon's decision. The participants were followed-up for 3, 6 and 12 months for natural or artificial conception as well as for cyst recurrence.

Chemical pregnancy was positive in 52% of the women in the aspiration group and 53.8% in the retention group. Ongoing pregnancy (44% vs 46.2%, p = 0.584) and live birth (40% vs 46.2%, p = 0.490) were reported marginally higher in the retention group compared with the aspiration group, and the differences were not statistically significant. Moreover, the recurrence rate were found to be 48.1% and 37.5% in the aspiration and retention groups, respectively (p = 0.542). The cysts size in the retention group was significantly correlated to the recurrence rate.

Both the aspiration and left in situ of ethanol 95% sclerotherapy have the similar impact on the treatment of ovarian endometrioma regarding pregnancy and recurrence rate. However, larger randomized studies with strict inclusion criteria are needed.

They participate in wide range of biological processes such as the modulating of chromatin structure, transcription, translation, and post-translation modification. In addition, based on their unique expression profiles and their association with clinical abnormalities such as those of related to male reproductive diseases, they can be used to develop therapeutic methods and biomarkers for screening of the diseases. In this study, we will review the identified lncRNAs and their molecular functions in the pathogenesis of male reproductive diseases such as prostate cancer, benign prostatic hyperplasia, prostatitis, testicular cancer, varicocele, and sperm abnormalities.The S1 subunit of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein contains an immunogenic receptor-binding domain (RBD), which is a promising candidate for the development of a potential vaccine. This study demonstrated that intradermal delivery of an S-RBD vaccine using a dissolvable microneedle skin patch can induce both significant B-cell and significant T-cell responses against S-RBD. Importantly, the outcomes were comparable to that of conventional bolus injection.Covid-19 has already taught us that the greatest public health challenges of our generation will show no respect for national boundaries, will impact lives and health of people of all nations, and will affect economies and quality of life in unprecedented ways. The types of rapid learning envisioned to address Covid-19 and future public health crises require a systems approach that enables sharing of data and lessons learned at scale. Agreement on a systems approach augmented by technology and standards will be foundational to making such learning meaningful and to ensuring its scientific integrity. With this purpose in mind, a group of individuals from Spain, Italy, and the United States have formed a transatlantic collaboration, with the aim of generating a proposed comprehensive standards-based systems approach and data-driven framework for collection, management, and analysis of high-quality data. This framework will inform decisions in managing clinical responses and social measures to overcome the Covid-19 global pandemic and to prepare for future public health crises. We first argue that standardized data of the type now common in global regulated clinical research is the essential fuel that will power a global system for addressing (and preventing) current and future pandemics. We then present a blueprint for a system that will put these data to use in driving a range of key decisions. In the context of this system, we describe and categorize the specific types of data the system will require for different purposes and document the standards currently in use for each of these categories in the three nations participating in this work. In so doing, we anticipate some of the challenges to harmonizing these data but also suggest opportunities for further global standardization and harmonization. While we have scaled this transnational effort to three nations, we hope to stimulate an international dialogue with a culmination of realizing such a system.
Adrenal myelolipoma (AM) is a benign tumor composed of mature fat cells and hemopoietic elements. Most AMs are incidental findings on imaging and clinically asymptomatic. The purpose of this case report is to describe a rare case of AM and explore its clinical manifestations, imaging features, and treatment.

In this study, we report a case of a rapidly growing right AM in a patient with uncontrolled hemoglobin sickle cell disease. A 38-year-old male presented to our institution's endocrine surgery clinic for evaluation of an enlarging right adrenal mass. This mass was incidentally found during an abdominal ultrasound performed for transaminitis and thrombocytopenia. Patient was asymptomatic without any abdominal discomfort, back pain, nausea, or vomiting.

Patient was lost to follow up until 2018. Follow-up computed tomography scan in 2018 showed the right adrenal mass measuring 12.3 cm in greatest dimension with significant macroscopic fat. Given the imaging features, AM was the presumed diagnosis. However, with a medical history of uncontrolled sickle cell disease, extra-medullary hematopoiesis and rapidly growing liposarcoma could not be ruled out. Surgical excision was performed due to size and significant tumor growth. Diagnosis was confirmed with histopathology and revealed myelolipoma.

Image characteristics can be helpful in diagnosis of AM; however, the appearance of this lesion on computed tomography can be similar to other adrenal gland pathologies such as liposarcoma and mass-forming extramedullary hematopoiesis. Percutaneous needle biopsy may be indicated if the diagnosis remains unclear.

From the very beginning, research ethics committees (RECs) have been called upon and mobilized to carry out the scientific and ethical evaluations of research projects to achieve a sound analysis of their risk/benefit balance. The aim of this article is to present an ethical reflection on the challenges and consequences of the fast-track procedure for the evaluation of COVID-19 research projects in the context of a public health emergency. Indeed, a large number of protocols of reduced rigor were hastily prepared without collaboration between researchers and in the absence of national regulation. As a result, a number of ethical dilemmas have emerged concerning the opposing needs of pragmatism imposed by the emergency context and the ethical principles that should govern the conduct of research. Moreover, the dispersion of these individual projects, aggravated by excessive media coverage of specific treatments, has resulted in a weakened impact of the research in the epidemic context.
