Prognosis Associated with Complete Pathological Response Following Neoadjuvant Treatment for PancreaTic AdenOcarciNOma in the FOFLIRINOX Era: the Multicenter TONO Study.

Background: The use of multiagent FOLFIRINOX chemotherapy for pancreatic adenocarcinoma in a neoadjuvant setting has been associated with an increased rate of complete pathological response (CPR) after surgery. This study investigated the long-term outcomes of patients with CPR in a multicenter setting to identify prognostic factors for overall survival (OS) and recurrence-free survival (RFS).

Methods: This retrospective cohort study examined biopsy-proven pancreatic adenocarcinomas with CPR after neoadjuvant chemotherapy or chemoradiotherapy and surgery, between January 2006 and December 2023 across 22 French and  2 Belgian centers.

Evaluation of GnRH- versus estradiol-based protocols for ovulation synchronization in postpartum Bos taurus grazing beef cows submitted to fixed-time artificial insemination.

This study compared the effect of a 7-day estradiol- and a 7-day GnRH-based FTAI protocol versus a presynchronized GnRH-based FTAI protocol (7 & 7 GnRH) on pregnancy per AI (P/AI) in multiparous postpartum Angus cows. Cows were blocked according to presence/absence of a CL, body condition score, and days postpartum and assigned randomly to one of three treatments: I) 7-day EB (n = 368), estradiol benzoate (EB) and intravaginal progesterone-(P4)-releasing device (IVPD) on Day -10, prostaglandin F (PG), equine chorionic gonadotropin (eCG) and estradiol cypionate (ECP) at IVPD removal on Day -3 with FTAI done on Day -1 (54 ± 2 h after IVPD removal); II) 7-day GnRH (n = 367), GnRH at IVPD insertion on Day -10, PG and eCG at IVPD removal on Day -3 with GnRH and FTAI on Day 0 (66 ± 2 h after IVPD removal); and III) 7 & 7 GnRH (n = 361), PG at IVPD insertion on Day -17, GnRH on Day -10, IVPD removal, PG and eCG on Day -3 with GnRH and FTAI on Day 0 (66 ± 2 h after IVPD removal). Preovulatory follicle diameter, corpus luteum (CL) presence, CL area, and P4 concentration were determined at IVPD removal, as well as estrus expression at FTAI and P/AI between 35 and 40 days after FTAI.

Reduction of sacsin levels in peripheral blood mononuclear cells as a diagnostic tool for spastic ataxia of Charlevoix-Saguenay.

Autosomal recessive spastic ataxia of Charlevoix-Saguenay is a rare neurodegenerative disease caused by biallelic variants in the gene encoding for sacsin. More than 200 pathogenic variants have been identified to date, most of which are missense. It is likely that the prevalence of autosomal recessive spastic ataxia of Charlevoix-Saguenay is underestimated due to the lack of an efficient diagnostic tool able to validate variants of uncertain significance.

Vitamin D affects the risk of disease activity in multiple sclerosis.

Background: Vitamin D (VitD) affects the risk of multiple sclerosis (MS), but the impact on disease activity is controversial. We assessed whether VitD is associated with the No-Evidence of Disease Activity-3 (NEDA-3) status at 2 years from disease-modifying treatment (DMT) start, and whether this association is causal or the result of confounding factors. Furthermore, we explored if a genetic predisposition to higher VitD levels affects the risk of disease activity.

Prospective observational study to evaluate treatment satisfaction and effectiveness in patients with relapsing multiple sclerosis starting cladribine tablets (CLADREAL) in Italy.

Disease-modifying therapies (DMTs) for multiple sclerosis (MS) reduce relapse frequency, magnetic resonance imaging (MRI) activity, and slow disability progression. Numerous DMTs are approved for relapsing forms of MS although real-world data on patient-reported outcomes (PROs) and quality of life (QoL) are needed to inform treatment choice. Immune reconstitution therapy with cladribine tablets is a highly effective treatment for relapsing MS (RMS).

Comparison of Gonadotropin-Releasing Hormone versus Estrogen-Based Fixed-Time Artificial Insemination Protocols in Grazing Suckled Beef Cows.

Fixed-timed artificial insemination (FTAI) protocols for beef cattle in South America are primarily based on estradiol esters and intravaginal progesterone-releasing devices (IVPD). The objective of this study was to determine the optimal gonadotropin-releasing hormone (GnRH)-based protocol as an alternative to the use of estrogen-based protocols in grazing suckling beef cows. All cows received an IVPD on the day of protocol initiation and prostaglandin F (PG) plus equine chorionic gonadotropin (eCG) treatments at the time of IVPD removal.

Epidemiology and antimicrobial resistance profile of Neisseria gonorrhoeae in Catalonia, Spain, 2016-2019.

Antimicrobial resistance data for Neisseria gonorrhoeae is globally sparse and resistant strains are emerging in Catalonia. We aim to describe epidemiological and antimicrobial resistance in all patients infected with N. gonorrhoeae during the period from 2016 to 2019, using available antimicrobial susceptibility data.

Effectiveness and safety profile of cladribine in an Italian real-life cohort of relapsing-remitting multiple sclerosis patients: a monocentric longitudinal observational study.

Introduction: Cladribine is approved for the treatment of active relapsing MS (RRMS), but its positioning in MS therapeutic scenario still needs to be fully elucidated.

Methods: This is a monocentric, observational, real-world study on RRMS patients treated with cladribine. Relapses, magnetic resonance imaging (MRI) activity, disability worsening, and loss of no-evidence-of-disease-activity-3 (NEDA-3) status were assessed as outcomes.

Risk HLA Variants Affect the T-Cell Repertoire in Multiple Sclerosis.

Background And Objectives: The major histocompatibility complex (MHC) locus has a predominant role in the genetic predisposition to multiple sclerosis (MS), with 32 associations found to be involved. We aimed to investigate the impact of MHC MS-risk alleles on T-cell repertoire in patients with MS.

Methods: We studied 161 untreated patients with relapsing-remitting MS for whom Class I and II human leukocyte antigen (HLA) alleles were inferred from whole-genome genotyping data, and T-cell receptor (TCR) CDR3 sequences were obtained through next-generation sequencing.

Transvaginal ultrasound-guided oocyte retrieval in cattle: State-of-the-art and its impact on the in vitro fertilization embryo production outcome.

Transvaginal ultrasound-guided oocyte retrieval (commonly called OPU) and in vitro embryo production (IVP) in cattle has shown significant progress in recent years, in part, as a result of a better understanding of the full potential of these tools by end users. The combination of OPU and IVP (OPU-IVP) has been successfully and widely commercially used worldwide. The main advantages are a greater number of embryos and pregnancies per unit of time, faster genetic progress due to donor quick turn around and more elite sires mating combinations, larger spectrum of female age (calves, prepuberal, heifer, cow) and condition (open, pregnant) from which to retrieve oocytes, a reduced number of sperm (even sexed) required to fertilize the oocytes, among other benefits.

Survival after Multimodal Treatment Including Surgery for Metastatic Esophageal Cancer: A Systematic Review.

(1) Background: The management of metastatic esophageal cancer is more often limited to palliative chemotherapy. Limited data are available regarding the role of surgery that remains controversial. The aim of this systematic review is to assess the survival outcome of surgically treated metastatic esophageal cancer patients.

Comparative analysis of tibial plateau fracture osteosynthesis: A finite element study.

This study presents a comparative structural finite element analysis between two different fixation methods for high-energy tibial plateau fractures: limited contact dynamic compression plate (LC-DCP) and locking compression plate (LCP). Several computational methods were employed to obtain an accurate finite element bone model with non-homogeneous properties. The goal is to evaluate the mechanical behavior of the fractured bone under each type of treatment within the scope of a single case study.

Early use of fingolimod is associated with better clinical outcomes in relapsing-remitting multiple sclerosis patients.

Background: Multiple sclerosis (MS) is a chronic autoimmune disease with huge heterogeneity in terms of clinical course, disease severity and treatment response. The need for a tailored treatment approach has emerged over the last few years. The present observational study aims to assess fingolimod (FTY) effectiveness in RRMS patients, stratifying them according to the disease-modifying treatments used before FTY, to identify subjects who could benefit more from this treatment.
