Ipsilateral Breast Carcinoma Recurrence: True Recurrence or New Primary? A Clinicopathologic and Molecular Study.

Determining whether an ipsilateral breast carcinoma recurrence is a true recurrence or a new primary remains challenging based solely on clinicopathologic features. Algorithms based on these features have estimated that up to 68% of recurrences might be new primaries. However, few studies have analyzed the clonal relationship between primary and secondary carcinomas to establish the true nature of recurrences.

Influenza vaccine outcomes: a meta-analysis revealing morbidity benefits amid low infection prevention.

Background: The morbidity and mortality associated with influenza viruses are a significant public health challenge. Annual vaccination against circulating influenza strains reduces hospitalisations and increases survival rates but requires a yearly redesign of vaccines against prevalent subtypes. The complex genetics of influenza viruses with high antigenic drift create an ongoing challenge in vaccine development to address dynamic influenza epidemiology.

SARS-CoV-2 infection and COVID-19 outcomes across mental disorders and the role of sex: A register-based study from Catalonia.

Introduction: This study investigated the risk of SARS-CoV-2 infection and severe COVID-19 outcomes among different mental health diagnoses and the role of sex in these associations.

Methods: Using electronic records from Catalonia, we identified adults receiving mental health care from 2017-2019 with diagnoses of non-affective psychosis (NAP), bipolar disorder (BD), depressive disorder (DEP), stress-related disorders, neurotic/somatoform disorders (NSD), and substance misuse (SUB) (exposed). The outcomes assessed were SARS-CoV-2 infection, COVID-19 hospitalization, and COVID-19-related death, compared to matched individuals without these mental disorders (unexposed).

Position statement of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis on the use of Telemedicine in Inflammatory Bowel Disease.

Inflammatory Bowel Disease (IBD) is a chronic digestive condition that requires continuous monitoring by healthcare professionals to determine appropriate therapy and manage short- and long-term complications. Telemedicine has become an essential approach for managing chronic conditions such as IBD, improving care accessibility and continuity, decreasing hospitalization rates, and optimizing patient follow-up. It enables rapid treatment adjustments and encourages patient self-management.

Unravelling molecular mechanisms in atherosclerosis using cellular models and omics technologies.

Despite the discovery and prevalent clinical use of potent lipid-lowering therapies, including statins and PCSK9 inhibitors, cardiovascular diseases (CVD) caused by atherosclerosis remain a large unmet clinical need, accounting for frequent deaths worldwide. The pathogenesis of atherosclerosis is a complex process underlying the presence of modifiable and non-modifiable risk factors affecting several cell types including endothelial cells (ECs), monocytes/macrophages, smooth muscle cells (SMCs) and T cells. Heterogeneous composition of the plaque and its morphology could lead to rupture or erosion causing thrombosis, even a sudden death.

Long-Term Follow Up in Anti-Contactin-1 Autoimmune Nodopathy.

Objective: To analyze long-term clinical and biomarker features of anti-contactin-1 (CNTN1) autoimmune nodopathy (AN).

Methods: Patients with anti-CNTN1 autoimmune nodopathy detected in our laboratory from which clinical information was available were included. Clinical features and treatment response were retrospectively collected.

SIRT1 Mediates the Antagonism of Wnt/β-Catenin Pathway by Vitamin D in Colon Carcinoma Cells.

Cancer initiation and progression result from genetic and epigenetic alterations caused by interactions between environmental and endogenous factors leading to aberrant cell signalling. Colorectal cancers (CRC) are linked to abnormal activation of the Wnt/β-catenin pathway, whose key feature is the nuclear accumulation of acetylated β-catenin in colon epithelial cells. Nuclear β-catenin acts as a transcriptional co-activator, targeting genes involved in cell proliferation and invasion.

Formin-like 1β phosphorylation at S1086 is necessary for secretory polarized traffic of exosomes at the immune synapse in Jurkat T lymphocytes.

We analyzed here how formin-like 1 β (FMNL1β), an actin cytoskeleton-regulatory protein, regulates microtubule-organizing center (MTOC) and multivesicular bodies (MVB) polarization and exosome secretion at an immune synapse (IS) model in a phosphorylation-dependent manner. IS formation was associated with transient recruitment of FMNL1β to the IS, which was independent of protein kinase C δ (PKCδ). Simultaneous RNA interference of all FMNL1 isoforms prevented MTOC/MVB polarization and exosome secretion, which were restored by FMNL1βWT expression.

Types, behaviour and therapeutic requirements of inflammatory pouch disorders: Results from the RESERVO study of GETECCU.

Background And Aims: Inflammatory pouch disorders exhibit a heterogeneous clinical spectrum and therapeutic requirements have not been properly studied.

Methods: This retrospective, multicentre study included ulcerative colitis patients with ileal pouch construction and were later diagnosed with an inflammatory pouch disorder between 1995 and 2020. Classifications, behaviour and therapies applied were recorded and compared in the long-term.

Prevalence of Antidepressant Prescriptions for Community-Dwelling Adults Diagnosed with Depressive Disorder in the UK: A Systematic Review.

The UK National Institute for Health and Care Excellence (NICE) guidance for the treatment of depression is widely followed and has international influence. According to these guidelines, antidepressant medications are recommended for moderate to severe depression. Nonetheless, antidepressants are increasingly prescribed, including for cases of subthreshold and mild depression.

The European Society of Cardiology quality indicators in atrial fibrillation in centers of excellence in Spain: the SEC-EXCELENTE FA registry.

Introduction And Objectives: By 2022, 9 centers had been accredited by the Spanish Society of Cardiology for the atrial fibrillation (AF) process. Our objective was to evaluate the performance of these centers based on the quality indicators (QIs) proposed by the European Society of Cardiology (ESC) in 2020.

Methods: Adults with AF who were attended in the cardiology departments of participating centers during the second week of May 2019 were included in a retrospective registry (n=797, age 72±11 years, 60% male).

Long-chain polyunsaturated fatty acids supplementation and sepsis: a systematic review and meta-analysis.

Background: Long chain polyunsaturated fatty acids (LCPUFAs) have proven to be essential for development in preterm infants and have been studied for their capacity to reduce inflammation and infection rates, including sepsis in enteral and parenteral nutrition. The aim of this review and meta-analysis is to gather the information available on this subject to determine if n-3 polyunsaturated fatty acids can reduce sepsis incidence in preterm infants.

Methods: This systematic review was conducted by searching in the databases MEDLINE (via PubMed), ISI-Web of Science, EMBASE, SCOPUS, SciELO, and Cochrane Library databases.

Immunogenicity of a third dose with mRNA-vaccines in the ChAdOx1-S/BNT162b2 vaccination regimen against SARS-CoV-2 variants.

CombiVacS study has demonstrated a strong immune response of the heterologous ChAdOx1-S/BNT162b2 vaccine combination. The primary outcomes of the study were to assess the humoral immune response against SARS-CoV-2, 28 days after a third dose of a mRNA vaccine, in subjects that received a previous prime-boost scheme with ChAdOx1-S/BNT162b2. Secondary outcomes extended the study to 3 and 6 months.

Telemonitoring of Active Inflammatory Bowel Disease Using the App TECCU: Short-Term Results of a Multicenter Trial of GETECCU.

Background: Telemonitoring for inflammatory bowel disease (IBD) has not consistently demonstrated superiority over standard care; however, noninferiority may be an acceptable outcome if remote care proves to be more efficient.

Objective: This study aims to compare the remission time and quality of life of patients with active IBD managed through standard care versus the TECCU (Telemonitoring of Crohn Disease and Ulcerative Colitis) app.

Methods: A 2-arm, randomized, multicenter trial with a noninferiority design was conducted across 24 hospitals in Spain.

Cytosolic protein translation regulates cell asymmetry and function in early TCR activation of human CD8 T lymphocytes.

Introduction: CD8 cytotoxic T lymphocytes (CTLs) are highly effective in defending against viral infections and tumours. They are activated through the recognition of peptide-MHC-I complex by the T-cell receptor (TCR) and co-stimulation. This cognate interaction promotes the organisation of intimate cell-cell connections that involve cytoskeleton rearrangement to enable effector function and clearance of the target cell.

Human T-cell receptor triggering requires inactivation of Lim kinase-1 by Slingshot-1 phosphatase.

Actin dynamics control early T-cell receptor (TCR) signalling during T-cell activation. However, the precise regulation of initial actin rearrangements is not completely understood. Here, we have investigated the regulatory role of the phosphatase Slingshot-1 (SSH1) in this process.
