Objective: 17β-Hydroxysteroid dehydrogenase 3 deficiency (17β-HSDD) and 5α-reductase type 2 deficiency (5α-RD) are rare 46,XY differences of sex development (DSD). This study aims to enlarge the limited knowledge on long-term gonadal function and gonadal pathology in these conditions.

Design: Retrospective multicentre cohort study.

Discovery of 22(S)-23-phenyl-24-norchol-5-en-3β,22-diol (PFM046) as the first-in-class, steroidal, non-sulfated Liver X Receptor antagonist with anticancer activity.

A plethora of studies have demonstrated the crucial role played by Liver X Receptors (LXRs) in cancer. However, whether LXRs activation results in pro-versus anti-tumor effects is still matter of debate. Recently, we have reported the ability of 22(S)-hydroxycholesterol-3-sulfate (PFM037) to antagonize LXRα activity, and, at the same time, its capability to improve in-vivo anti-tumor immune responses.

Behind the scenes: exploring neurological journal editors' work habits, decisions, and potential sources of conflict of interest.

Background And Objectives: Editors of scientific journals play a key role in the health-related research process. Our study aims to characterize the demographics, work habits, decision-making processes, and ethical challenges faced by editors of neurological journals and to evaluate associations between editor or journal characteristics and editorial decisions, as well as sources of conflict of interest.

Methods: Cross-sectional study involving editors from neurological journals that fell above the 50th percentile in the Scimago rankings.

RENEWED: A follow-up study of the opicinumab phase 2 RENEW study in participants with acute optic neuritis.

Background: The randomized, phase 2 RENEW trial (NCT01721161) evaluated efficacy/safety of opicinumab (anti-LINGO-1) versus placebo in patients with first-episode unilateral acute optic neuritis (AON). Although no significant differences in the latency recovery of visual evoked potential (VEP) were observed between opicinumab and placebo groups in the intention to treat (ITT) population, the prespecified per-protocol (PP) population showed better recovery with opicinumab than with placebo. RENEWED (NCT02657915) was a one-visit, follow-up study 2 years after the last RENEW study visit (Week 32) designed to assess the long-term electrophysiological and clinical outcomes for participants previously enrolled and having received study treatment in RENEW.

Loss of NUMB drives aggressive bladder cancer via a RHOA/ROCK/YAP signaling axis.

Advances in bladder cancer (BCa) treatment have been hampered by the lack of predictive biomarkers and targeted therapies. Here, we demonstrate that loss of the tumor suppressor NUMB promotes aggressive bladder tumorigenesis and worsens disease outcomes. Retrospective cohort studies show that NUMB-loss correlates with poor prognosis in post-cystectomy muscle-invasive BCa patients and increased risk of muscle invasion progression in non-muscle invasive BCa patients.

Development and validation of an electronic Symbol-Digit Modalities Test for remote monitoring of people with multiple sclerosis.

Background: Computerized cognitive tests may extend the reach of cognitive screening and monitoring to those with mobility issues or living in remote areas. Moreover, it could enable frequent and autonomous remote cognitive assessments in people with multiple sclerosis (pwMS) on account of its reduced economic and organizational costs. This may further improve our understanding of longitudinal trends and significantly improve the standard of care for pwMS living in remote areas or with mobility limitations.

Gynecomastia and Its Management In Boys With Partial Androgen Insensitivity Syndrome.

Introduction: Partial androgen insensitivity syndrome (PAIS) is a rare condition that is reported to be commonly associated with gynecomastia in males.

Objectives: To assess the management of gynecomastia in male PAIS.

Materials And Methods: Retrospective review of males with PAIS over the age of 10 years in the I-DSD registry.

LIM-domain-only 4 (LMO4) enhances CD8 T-cell stemness and tumor rejection by boosting IL-21-STAT3 signaling.

High frequencies of stem-like memory T cells in infusion products correlate with superior patient outcomes across multiple T cell therapy trials. Herein, we analyzed a published CRISPR activation screening to identify transcriptional regulators that could be harnessed to augment stem-like behavior in CD8 T cells. Using IFN-γ production as a proxy for CD8 T cell terminal differentiation, LMO4 emerged among the top hits inhibiting the development of effectors cells.

Subfoveal neurosensory detachment flattening and observe (SNF-Ob) approach for the management of Ci-DMO - a multicentric study.

Purpose: To understand subfoveal neurosensory detachment flattening and observe (SNF-Ob) strategy and its relationship with visual acuity in the management of centre-involved diabetic macular oedema (Ci-DMO).

Methods: This was a multicentric retrospective observational study. We reviewed data of 188 eyes of 130 patients who presented with Ci-DMO with subfoveal neurosensory detachment (NSD) and treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents or steroids.

Implications of noncoding regulatory functions in the development of insulinomas.

Insulinomas are rare neuroendocrine tumors arising from pancreatic β cells, characterized by aberrant proliferation and altered insulin secretion, leading to glucose homeostasis failure. With the aim of uncovering the role of noncoding regulatory regions and their aberrations in the development of these tumors, we coupled epigenetic and transcriptome profiling with whole-genome sequencing. As a result, we unraveled somatic mutations associated with changes in regulatory functions.

Extracellular vesicles secreted by human aneuploid embryos present a distinct transcriptomic profile and upregulate MUC1 transcription in decidualised endometrial stromal cells.

Study Question: Do extracellular vesicles (EVs) secreted by aneuploid human embryos possess a unique transcriptomic profile that elicits a relevant transcriptomic response in decidualized primary endometrial stromal cells (dESCs)?

Summary Answer: Aneuploid embryo-derived EVs contain transcripts of , , , and with differential abundance from euploid embryo-derived EVs and induce upregulation of transcript in dESCs.

What Is Known Already: We have previously reported that IVF embryos secrete EVs that can be internalized by ESCs, conceptualizing that successful implantation to the endometrium is facilitated by EVs. Whether these EVs may additionally serve as biomarkers of ploidy status is unknown.

Global experience of faricimab in clinical settings - a review.

Introduction: Faricimab is a bispecific antibody that acts to reduce neoangiogenesis in exudative retinal vascular disorders. It is approved for use in neovascular age-related macular degeneration and diabetic macular edema. We review the published efficacy and safety of faricimab in clinical settings.

Multimodal Imaging of Vitreo-Retinal Lymphoma: A Comprehensive Review.

Purpose: Vitreoretinal lymphoma (VRL) is a rare lymphoma affecting the vitreous and the retina. Clinical diagnosis is challenging and often delayed and may lead to aggravated prognosis. This study aims to review multimodal imaging findings in VRL.

Increased interhemispheric functional connectivity after right anodal tDCS in chronic non-fluent aphasia: preliminary findings.

Introduction: Anodal transcranial Direct Current Stimulation (tDCS) is a non-invasive, low-cost and environment-friendly brain neuromodulation technique that increases cortical excitability. In post-stroke aphasia, the role of the right hemisphere in language recovery remains debated. In this preliminary study, we aimed to investigate the efficacy of excitatory tDCS on the right hemisphere in chronic aphasic patients.

Impact of multiple treatment cycles with anti-CGRP monoclonal antibodies on migraine course: focus on discontinuation periods. Insights from the multicenter, prospective, I-GRAINE study.

Objectives: While a single 12-month treatment cycle (TrC) with anti-CGRP mAbs is not disease-modifying for most patients, there is limited understanding of the effects of multiple TrCs on migraine course. We evaluated whether a second TrC might modify the migraine course by comparing the occurrence of migraine relapse after discontinuation of the second TrC to that following the cessation of the first TrC.

Methods: In a real-life, multicenter, prospective study we considered all consecutive patients diagnosed with high-frequency episodic migraine (HFEM) or chronic migraine (CM) with > 3 treatment failures and treated with any anti-CGRP mAbs for ≥ 2 consecutive 12-month TrCs who were responders at week 12.

Genetic variants affecting NQO1 protein levels impact the efficacy of idebenone treatment in Leber hereditary optic neuropathy.

Idebenone, the only approved treatment for Leber hereditary optic neuropathy (LHON), promotes recovery of visual function in up to 50% of patients, but we can neither predict nor understand the non-responders. Idebenone is reduced by the cytosolic NAD(P)H oxidoreductase I (NQO1) and directly shuttles electrons to respiratory complex III, bypassing complex I affected in LHON. We show here that two polymorphic variants drastically reduce NQO1 protein levels when homozygous or compound heterozygous.
