Inter-centre reliability in embryo grading across several IVF clinics is limited: implications for embryo selection.

RESEARCH QUESTION: What is the intra- and inter-centre reliability in embryo grading performed according to the Istanbul Consensus across several IVF clinics? DESIGN: Forty Day 3 embryos and 40 blastocysts were photographed on three focal planes. Senior and junior embryologists from 65 clinics were invited to grade them according to the Istanbul Consensus (Study Phase I). All participants then attended interactive training where a panel of experts graded the same embryos (Study Phase II). Finally, a second set of pictures was sent to both embryologists and experts for a blinded evaluation (Study Phase III). Intra-centre reliability was reported for Study Phase I as Cohen's kappa between senior and junior embryologists; inter-centre reliability was instead calculated between senior/junior embryologists and experts in Study Phase I versus III to outline improvements after training (i.e. upgrade of Cohen's kappa category according to Landis and Koch). RESULTS: Thirty-six embryologists from 18 centres participated (28% participation rate). The intra-centre reliability was (i) substantial (0.63) for blastomere symmetry (range -0.02 to 1.0), (ii) substantial (0.72) for fragmentation (range 0.29-1.0), (iii) substantial (0.66) for blastocyst expansion (range 0.19-1.0), (iv) moderate (0.59) for inner cell mass quality (range 0.07-0.92), (v) moderate (0.56) for trophectoderm quality (range 0.01-0.97). The inter-centre reliability showed an overall improvement from Study Phase I to III, from fair (0.21-0.4) to moderate (0.41-0.6) for all parameters under analysis, except for blastomere fragmentation among senior embryologists, which was already moderate before training. CONCLUSIONS: Intra-centre reliability was generally moderate/substantial, while inter-centre reliability was just fair. The interactive training improved it to moderate, hence this workflow was deemed helpful. The establishment of external quality assessment services (e.g. UK NEQAS) and the avant-garde of artificial intelligence might further improve the reliability of this key practice for embryo selection.

When embryology meets genetics: the definition of developmentally incompetent preimplantation embryos (DIPE)-the consensus of two Italian scientific societies.

A clear definition of developmentally incompetent preimplantation embryo (DIPE) in literature is still missing, while several scientific societies are discussing this challenging topic. From both a clinical and scientific perspective, the identification of embryos unfit for reproductive purpose is crucial. This aim should be pursued in light of all diagnostic technologies for embryo evaluation, encompassing also genetic analyses, of recent implementation in IVF. The Italian context is characterized by an unusual scenario: embryos can be discarded only if not viable and cannot be used for research purposes either. Therefore, thousands of embryos, diagnosed as affected and/or aneuploid as resulting from preimplantation genetic testing (PGT) and clinically not utilizable, are cryopreserved and stored indefinitely, with important psychological, legal, and financial implications. With the aim of updating the definition of DIPE, also on the basis of the embryo genetic status, the Italian Society of Embryology, Reproduction and Research (SIERR) and the Italian Society of Human Genetic (SIGU) reviewed the literature on this topic, found a consensus, and produced a list of relevant criteria.

Does Bariatric Surgery Improve Assisted Reproductive Technology Outcomes in Obese Infertile Women?

BACKGROUND: Little is known about the impact of bariatric surgery on obese infertile women seeking an assisted reproductive technology. METHODS: All obese women with a history of assisted reproductive technology (ART) failure that underwent ART treatment cycles both prior to and following bariatric surgery were included. ART outcomes were compared evaluating the duration and dose of gonadotrophins used; the measurement of day 3 FSH; the anti-mullerian hormone dosage; the number of follicles >15 mm; the number of retrieved and fertilized oocytes; the number of metaphase II, metaphase I and germinal vesicle oocytes; the number of embryos obtained; the number of top-quality oocytes and embryos; the number of transferred embryo; the pregnancy rate and the live birth rate. RESULTS: Forty women were included. The total number of gonadotropin units required and in the length of stimulation following bariatric surgery decreased (p = .001), with an increase of the number of follicles ≥15 mm (p = .005), of retrieved oocytes (p = .004), of top-quality oocytes (p = .001) and metaphase II oocytes (p = .008). More oocytes were fertilized (4.2 ± 1.7 vs 5.3 ± 2.4; p = .02). After surgery, we have registered also a better number of top-quality embryos (0.5 ± 0.6 vs 1.1 ± 0.9; p = .003). Pregnancy rate following the bariatric surgery increased to 15/40 (37.5%) (p < .001), and live birth rate (LBR) increased to 14/40 (35%) in the post-surgery group (p<. 001). CONCLUSIONS: Although additional research would be useful to draw definitive conclusion, our results appear to be encouraging enough to suggest the use of bariatric surgery in obese infertile women seeking an ART treatment.

Incidence of Successful Pregnancy After Weight Loss Interventions in Infertile Women: a Systematic Review and Meta-Analysis of the Literature.

Little is known about the impact of weight loss interventions on pregnancy rate. A systematic review with meta-analysis of literature has been performed to evaluate the incidence of successful pregnancy after bariatric interventions in infertile women. By pooling together data from 589 infertile obese women, we have been able to provide an aggregate estimation of successful pregnancy after weight loss interventions. Our results showed an impressive high incidence (58%) of infertile women who become spontaneously pregnant after surgery. Based on our results, bariatric interventions could be included in the treatment of obesity-related infertility. However, the results must be interpreted with caution owning to the quality of the data provided by included studies. Further ad hoc studies are needed to validate the effectiveness of bariatric interventions on reproductive function.

Lymph nodes fine needle cytology in the diagnosis of infectious diseases: clinical settings.

Lymph node reactive hyperplasia, caused by specific infectious etiologic factors, represents the most frequent cause of enlarged peripheral lymph nodes. The main infectious agents are viruses, pyogenic bacteria, mycobacteria, fungi and protozoa that may determine unspecific or specific pathological entities, such as cat-scratch disease, toxoplasmosis or infectious mononucleosis. Lymph node fine needle cytology (FNC) is a safe, simple, cost-effective and efficient technique that quickly provides information about the cell population and the nature of the process. FNC can also provide suitable material for ancillary techniques, such as flow cytometry, immunocytochemistry, molecular biology and microbiological examinations. This study focuses on the cytological features of benign lymphadenopathy of infectious origin and their possible contribution to the clinical setting definition of corresponding patients.

Lymph nodes Fine Needle Cytology in the diagnosis of infectious diseases: cytological and histological correlations.

Fine Needle Cytology (FNC) is often used in the diagnosis of lymph node enlargement as first diagnostic procedure. In some cases different cytological features may occur, with different histological aspects. In other cases, FNC samples are neither representative nor sufficient to exclude a possible lymphoproliferative process or a metastasis. In these cases, specific ancillary techniques such as microbiological tests, immunocytochemistry, flow cytometry or molecular biology procedures may be used to assess the benign reactive nature of lymph node enlargement, allow clinical surveillance and avoid surgical biopsies. Cytology and ancillary techniques may also identify, in selected cases, possible aetiological agents. Notwithstanding these procedures, FNC unsolvable cases may occur; in these cases, indication for a direct histological examination should be promptly given in order to avoid any delay to further investigations and appropriate treatments. This study reports the most common cytological patterns occurring in reactive lymph nodes as well as ancillary techniques required in different conditions. Lymph nodal FNC should be performed by expert cytopathologists ensuring a safe and correct execution and a rapid evaluation of the smears for the assessment and the application of specific ancillary techniques.

Multiple metachronus proliferative fasciitis occurring in different anatomic regions: a case report and review of the literature.

Proliferative fasciitis is a benign lesion that usually has a self-limited course and rarely recurs after excision. In the literature, the multifocal occurrence of PF in different anatomic sites has not been reported so far. In this report, we describe the clinical case of a 30-year-old woman with two metachronous proliferative fasciitis occurring firstly in the orbit and, after 18 months, in the forearm; we also review the available literature on this topic, outlining guidelines for therapy and the follow-up of these patients.

Immunoglobulin heavy-chain fluorescence in situ hybridization-chromogenic in situ hybridization DNA probe split signal in the clonality assessment of lymphoproliferative processes on cytological samples.

BACKGROUND: The human immunoglobulin heavy-chain (IGH) locus at chromosome 14q32 is frequently involved in different translocations of non-Hodgkin lymphoma (NHL), and the detection of any breakage involving the IGH locus should identify a B-cell NHL. The split-signal IGH fluorescence in situ hybridization-chromogenic in situ hybridization (FISH-CISH) DNA probe is a mixture of 2 fluorochrome-labeled DNAs: a green one that binds the telomeric segment and a red one that binds the centromeric segment, both on the IGH breakpoint. In the current study, the authors tested the capability of the IGH FISH-CISH DNA probe to detect IGH translocations and diagnose B-cell lymphoproliferative processes on cytological samples. METHODS: Fifty cytological specimens from cases of lymphoproliferative processes were tested using the split-signal IGH FISH-CISH DNA probe and the results were compared with light-chain assessment by flow cytometry (FC), IGH status was tested by polymerase chain reaction (PCR), and clinicohistological data. RESULTS: The signal score produced comparable results on FISH and CISH analysis and detected 29 positive, 15 negative, and 6 inadequate cases; there were 29 true-positive cases (66%), 9 true-negative cases (20%), 6 false-negative cases (14%), and no false-positive cases (0%). Comparing the sensitivity of the IGH FISH-CISH DNA split probe with FC and PCR, the highest sensitivity was obtained by FC, followed by FISH-CISH and PCR. CONCLUSIONS: The split-signal IGH FISH-CISH DNA probe is effective in detecting any translocation involving the IGH locus. This probe can be used on different samples from different B-cell lymphoproliferative processes, although it is not useful for classifying specific entities.
