A systematic review and meta-analysis of double trophectoderm biopsy and/or cryopreservation in PGT: balancing the need for a diagnosis against the risk of harm.

Background: To prevent the transfer of embryos affected by monogenic conditions and/or chromosomal defects, preimplantation genetic testing (PGT) requires trophectoderm biopsy and cryopreservation. In 2-6% of biopsies, the diagnosis may be inconclusive due to DNA amplification failure or low-quality results. In these cases, a round of re-warming, re-biopsy, and re-cryopreservation is required to obtain a genetic diagnosis.

A multicycle approach through DuoStim with a progestin-primed ovarian stimulation (PPOS) protocol: a valuable option in poor prognosis patients undergoing PGT-A.

Purpose: This study is to evaluate the effectiveness of a PPOS protocol in poor prognosis patients undergoing IVF with DuoStim and PGT-A versus the conventional protocol with GnRH antagonist.

Methods: Retrospective cohort study encompassing 444 couples obtained matching one PPOS-DuoStim with two antagonist-DuoStim cycles at a private IVF center between 2020 and 2023 (average maternal age: 40 years, average cumulus-oocyte complexes collected after the first stimulation: 5). The study was powered to exclude a two-sided different euploid blastocyst rate per MII oocytes (EBR per MII) in the two groups (alpha = 0.

ICSI and PGT-A in PCOS phenotype-D patients: a matched case-control study versus idiopathic infertile women.

Purpose: To assess oocyte competence and embryo chromosomal constitution in phenotype-D PCOS women undergoing ICSI for PGT-A at the blastocyst stage.

Methods: Retrospective study at a private IVF center. In the period 2013-2021, 58 naïve phenotype-D PCOS women (i.

T-like CAR-T cells exhibit improved persistence and tumor control compared with conventional CAR-T cells in preclinical models.

Patients who receive chimeric antigen receptor (CAR)-T cells that are enriched in memory T cells exhibit better disease control as a result of increased expansion and persistence of the CAR-T cells. Human memory T cells include stem-like CD8 memory T cell progenitors that can become either functional stem-like T (T) cells or dysfunctional T progenitor exhausted (T) cells. To that end, we demonstrated that T cells were less abundant in infused CAR-T cell products in a phase 1 clinical trial testing Lewis Y-CAR-T cells (NCT03851146), and the infused CAR-T cells displayed poor persistence in patients.

Double stimulation for the management of poor-prognosis patients: where are we going?

Purpose Of Review: The technical improvements in IVF allowed the implementation of nonconventional ovarian stimulation protocols for some specific patients. Where time is crucial, such as with oncologic patients, poor-prognosis patients, patients with low ovarian reserve, and those with advanced maternal age, access to IVF treatment is even more critical. Some of these protocols might start in the late follicular phase, luteal phase, or involve both stimulations within the same ovarian cycle.

Generating CAR T cells from tumor-infiltrating lymphocytes.

Tumor-infiltrating lymphocytes (TILs) and chimeric antigen receptor (CAR) T-cell therapies have demonstrated promising, though limited, efficacy against melanoma. We designed a model system to explore the efficacy of dual specific T cells derived from melanoma patient TILs by transduction with a Her2-specific CAR. Metastatic melanoma cells in our biobank constitutively expressed Her2 antigen.

γδ T Cells in Merkel Cell Carcinomas Have a Proinflammatory Profile Prognostic of Patient Survival.

Merkel cell carcinomas (MCC) are immunogenic skin cancers associated with viral infection or UV mutagenesis. To study T-cell infiltrates in MCC, we analyzed 58 MCC lesions from 39 patients using multiplex-IHC/immunofluorescence (m-IHC/IF). CD4 or CD8 T cells comprised the majority of infiltrating T lymphocytes in most tumors.

Prognostic significance of the echocardiographic estimate of pulmonary hypertension and of right ventricular dysfunction in acute decompensated heart failure. A pilot study in HFrEF patients.

Background: Mortality following an admission for acute decompensated heart failure (ADHF) is high and risk stratification in this context remains a challenge. The objective of the present study was to assess whether a simple echocardiographic assessment of pulmonary hypertension (PH) and/or of right ventricular (RV) dysfunction is associated with cardiovascular events in a 1-year follow-up after hospital discharge.

Methods And Results: The present prospective longitudinal study included 214 patients admitted to hospital with a cardiologist-adjudicated diagnosis of ADHF and a left ventricular ejection fraction (LVEF) at echocardiography < 40%.

Complexity in internal medicine wards: A novel screening method and implications for management.

Rationale: Complexity is increasingly recognized as a critical variable in health care. However, there is still lack of practical tools to assess it and tackle the challenges that stem from it, particularly within hospitals.

Aims And Objective: To validate a simple novel screening method based on both objective and subjective criteria to identify patients with clinically complex hospitalization events.

Circulating tumour DNA reflects treatment response and clonal evolution in chronic lymphocytic leukaemia.

Several novel therapeutics are poised to change the natural history of chronic lymphocytic leukaemia (CLL) and the increasing use of these therapies has highlighted limitations of traditional disease monitoring methods. Here we demonstrate that circulating tumour DNA (ctDNA) is readily detectable in patients with CLL. Importantly, ctDNA does not simply mirror the genomic information contained within circulating malignant lymphocytes but instead parallels changes across different disease compartments following treatment with novel therapies.

Maximum left ventricular thickness and risk of sudden death in patients with hypertrophic cardiomyopathy.

Objectives: We sought to assess the relationship between maximum left ventricular (LV) wall thickness and outcome in patients with hypertrophic cardiomyopathy (HCM).

Background: An association between maximum LV wall thickness and risk of sudden death was suggested in HCM. This finding requires further investigation, given the important implications for risk stratification and treatment.
