Intracytoplasmic sperm injection versus conventional in vitro insemination in couples with non-male infertility factor in the 'real-world' setting: analysis of the HFEA registry.

Background: In assisted reproductive technology (ART), the choice between intracytoplasmic sperm injection (ICSI) and conventional in vitro insemination (IVF) remains a pivotal decision for couples with female or unexplained infertility. The hypothesis that ICSI may not confer significant improvements in live birth rates in the absence of a male infertility factor was explored in this study.

Methods: This was a retrospective collection of data recorded by the Human Fertilisation and Embryology Authority (HFEA) in the UK from 2005 to 2018 and analysed through regression analysis models on both the entire dataset and a matched-pair subset.

Chromosomal, gestational, and neonatal outcomes of embryos classified as a mosaic by preimplantation genetic testing for aneuploidy.

Objective: To understand the clinical risks associated with the transfer of embryos classified as a mosaic using preimplantation genetic testing for aneuploidy.

Design: Analysis of data collected between 2017 and 2023.

Setting: Multicenter.

Technological grandparents: how communication technologies can improve the well-being of the elderly?

The ageing of the population is one of the most significant social transformations that the twenty first century is showcasing and a challenge that impacts society at large. The elderly, inasmuch as everybody else, are confronted with continuous transformations that are induced by technology, although they seldom benefit from the opportunities that technology entails. The digital divide amongst various segments of the population is often age-related and due to different reasons, including biological, psychological, social and financial ones.

Pregnancy rate in IVF patients with unexpected poor response to ovarian stimulation.

Objective: To evaluate whether an unexpected poor response (cases with ≤3 oocytes) leads to a reduction in the pregnancy rate in IVF cycles compared to a suboptimal response (controls with 4-9 oocytes) in women with adequate ovarian reserve.

Methods: A nested case-control study performed in a retrospective cohort of couples undergoing IVF at the Infertility Unit of the ASST Lariana. Cases and controls had adequate ovarian reserve and were matched 1:1 for female age and number of previous cycles.

Using outcome data from one thousand mosaic embryo transfers to formulate an embryo ranking system for clinical use.

Objective: To study how the attributes of mosaicism identified during preimplantation genetic testing for aneuploidy relate to clinical outcomes, in order to formulate a ranking system of mosaic embryos for intrauterine transfer.

Design: Compiled analysis.

Setting: Multi-center.

Clinical Outcomes Deriving from Transfer of Blastocysts Developed in Day 7: a Systematic Review and Meta-Analysis of Frozen-Thawed IVF Cycles.

This meta-analysis aimed to assess the reproductive competence of blastocysts developed on day 7 compared with blastocysts developed on day 5/6. A systematic search was carried out to select relevant studies published before January 2020. Ten retrospective observational cohort studies were included.

ALADDIN study: does assisted hatching of vitrified/warmed blastocysts improve live birth rate? Protocol for a multicentric randomised controlled trial.

Introduction: Recent data suggest a higher clinical pregnancy rate performing assisted hatching (AH) on previously cryopreserved embryos but fail to demonstrate significant effects on live birth rate. However, current evidence is based on studies with a small sample size and may hide a type II error. Moreover, poor attention has been given to the specific effect of AH on frozen/thawed blastocysts.

Shooting STAR: reinterpreting the data from the 'Single Embryo TrAnsfeR of Euploid Embryo' randomized clinical trial.

Preimplantation genetic testing for aneuploidy (PGT-A) still remains controversial in clinical practice. Recently, the randomized controlled trial, 'Single Embryo TrAnsfeR of Euploid Embryo' (STAR) by Munné and coworkers showed a similar live birth rate per intention to treat in the two study groups (PGT-A and controls). A wrong diagnosis and/or biopsy-related damage to the embryo might underlie these results.

Does Endometriosis Influence the Embryo Quality and/or Development? Insights from a Large Retrospective Matched Cohort Study.

In vitro fertilization can be an effective tool to manage the endometriosis-associated infertility, which accounts for 10% of the strategy indications. Nevertheless, a negative effect of endometriosis on IVF outcomes has been suggested. The aim of this study was to evaluate the potential effect of endometriosis in the development of embryos at cleavege stage in assisted reproduction treatment cycles.

Whole-genome analysis uncovers recurrent IKZF1 inactivation and aberrant cell adhesion in blastic plasmacytoid dendritic cell neoplasm.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive hematological malignancy with a poorly understood pathobiology and no effective therapeutic options. Despite a few recurrent genetic defects (eg, single nucleotide changes, indels, large chromosomal aberrations) have been identified in BPDCN, none are disease-specific, and more importantly, none explain its genesis or clinical behavior. In this study, we performed the first high resolution whole-genome analysis of BPDCN with a special focus on structural genomic alterations by using whole-genome sequencing and RNA sequencing.

Oocyte Retrieval during Laparoscopic Vaginoplasty to Reduce Invasiveness in the Treatment of Mayer-Rokitansky-Küster-Hauser Syndrome.

Study Objective: To evaluate the treatment of patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome with a combination of oocyte retrieval and surgical vaginoplasty in a single laparoscopic procedure.

Design: A case series.

Setting: The study was conducted at 2 tertiary referral facilities for MRKH syndrome in Milan, Italy, between July 2017 and September 2018.

Assessment of pre-implantation genetic testing for embryo aneuploidies: A SWOT analysis.

The recently re-named pre-implantation genetic testing for determining embryo aneuploidies (PGT-A) is presently very popular although its acceptance by the scientific community is controversial. This approach still encounters drawbacks. This paper uses a SWOT (strengths, weaknesses, opportunities and threats) analysis to discuss salient points to be considered when examining the pre-implantation genetic testing (PGT-A) strategy to gather information from a range of perspectives.

Array-based CGH of primary cutaneous CD8+ aggressive EPIDERMO-tropic cytotoxic T-cell lymphoma.

Primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma (pcAECyTCL) is a rare provisionally categorized cutaneous lymphoma characterized by an aggressive course. Its pathogenesis and molecular mechanisms are still unknown, and only two individual cases have so far been molecularly characterized. The aim of this study was to define the pattern of numerical chromosomal alterations in tumor samples taken from 20 patients with pcAECyTCL at the time of diagnosis by means of array-comparative genomic hybridization (a-CGH).

Detection of IgE autoantibodies in mucous membrane pemphigoid and their association with disease severity.

Background: Mucous membrane pemphigoid (MMP) is an autoimmune disease characterized by scarring lesions at mucosal sites. Although the pathogenic role of specific IgG and/or IgA has been already demonstrated and the detection of these immunoglobulins is a criterion in the diagnosis of MMP, little is known about IgE role in this disease. Therefore, the main purpose of this study was to assess the presence of circulating and tissue bound IgE in patients with MMP and their possible correlations with clinical presentation and disease course.

Vitamin D and Endometrium: A Systematic Review of a Neglected Area of Research.

Growing evidence supports a role of vitamin D (VD) in reproductive health. Vitamin D receptor (VDR) is expressed in the ovary, endometrium, and myometrium. The biological actions of VD in fertility and reproductive tissues have been investigated but mainly using animal models.

Primary cutaneous acral CD8 positive T-cell lymphoma with extra-cutaneous involvement: A long-standing case with an unexpected progression.

Primary cutaneous acral CD8+ T-cell lymphoma (acral CD8+ TCL) is a new provisional entity characterized by acral skin lesions and an indolent course. We describe an extraordinary case characterized by relapsed nodules with CD8+ cytotoxic infiltrates on the left ear. After 35 years, the skin lesions spread to other acral sites, and a mass with the same histological features as the other skin lesions appeared on the nose.

Extracellular MicroRNA Signature of Human Helper T Cell Subsets in Health and Autoimmunity.

Upon T cell receptor stimulation, CD4 T helper (Th) lymphocytes release extracellular vesicles (EVs) containing microRNAs. However, no data are available on whether human CD4 T cell subsets release EVs containing different pattern of microRNAs. The present work aimed at filling this gap by assessing the microRNA content in EVs released upon T cell receptor stimulation of Th1, Th17, and T regulatory (Treg) cells.

Autoimmunity and Cytokine Imbalance in Inherited Epidermolysis Bullosa.

In order to evaluate the serum anti-skin autoantibodies and cytokine concentrations in patients with different epidermolysis bullosa (EB) types and severity, 42 EB patients and 38 controls were enrolled. Serum anti-skin antibodies were significantly higher in the patients than in the controls (p = 0.008, p < 0.

Clinicopathological and molecular study of primary cutaneous CD4+ small/medium-sized pleomorphic T-cell lymphoma.

Background: Primary cutaneous CD4+ small-/medium-sized pleomorphic T-cell lymphoma (CD4+ PCSM-TCL) is a rare lymphoproliferative disorder with a favorable prognosis. Distinguishing it from other cutaneous lymphomas is often a challenge.

Methods: We retrospectively collected CD4+PCSM-TCL cases from two centers (MD Anderson Cancer Center, USA and University of Milan, Italy) and evaluated their clinicopathological features.

Sézary Syndrome in a 17-Year-Old Boy: Clinicopathologic Features and Genomic Profile.

We describe the case of a 17-year-old Hispanic boy who had had erythroderma and diffuse lymphadenopathy for approximately 6 months. A diagnosis of Sézary syndrome was made on the basis of the histologic features of the skin; the presence of the same T-cell clone on the skin, blood, and bone marrow; and the high CD4(+) lymphocyte count with an aberrant phenotype in peripheral blood; bone marrow involvement was also present. The patient was treated with systemic gemcitabine and achieved partial remission.

Application of failure mode and effect analysis in an assisted reproduction technology laboratory.

Assisted reproduction technology laboratories have a very high degree of complexity. Mismatches of gametes or embryos can occur, with catastrophic consequences for patients. To minimize the risk of error, a multi-institutional working group applied failure mode and effects analysis (FMEA) to each critical activity/step as a method of risk assessment.
