Dolutegravir/Lamivudine for Maintenance of Virological Suppression in Persons with Historical Suspected or Confirmed Resistance to Lamivudine: Week 48 Results of a Single-Arm, Open-Label, Multicentre, Phase IIA Clinical Trial.

Background: We investigated the efficacy of dolutegravir/lamivudine for maintenance treatment for people with HIV and previous lamivudine resistance.

Methods: Open-label, single arm, multicentric clinical trial including virologically suppressed PWH with historical lamivudine resistance (confirmed by genotypic testing or suspected based on clinical history), no integrase resistance and CD4+ >200 cells/mm3 whose ART was changed to dolutegravir/lamivudine if the M184V/I mutation was not detected in baseline proviral DNA population sequencing. Proviral DNA next-generation sequencing (NGS) was retrospectively performed in baseline samples.

Sex-specific molecular hallmarks point to increased atherogenesis susceptibility in male senescence-accelerated mice.

Aims: The senescence-accelerated mouse (SAM) model has been extensively used to study neurological alterations associated with aging. The SAM model has also proved to be useful in the study of vascular aging, but there is still work to be done to better define its utility as a model of atherosclerosis, since contradictory data have been published and sex seems to play a crucial role in potential divergences.

Materials And Methods: With this in mind, we aimed to decipher the molecular mechanisms underlying early vascular aging on SAMP8 mice, analyzing the aorta of 10 months-old animals by means of in-depth proteomic analysis, considering sex-specific differences.

Some artificial intelligence tools may currently be useful in orthopedic surgery and traumatology.

Artificial intelligence (AI) can help in diagnosing fractures and demonstrating effusions, dislocations, and focal bone lesions in both adult and pediatric aged individuals and also aid in early tumor discovery (bone osteosarcoma) and in robot-assisted surgery. A recent AI model [Mask R-CNN (region-based convolutional neural network)] has shown to be dependable for detecting surgical target zones in pediatric hip and periarticular infections, offering a more convenient and quicker alternative to conventional methods. It can help inexperienced physicians in pre-treatment evaluations, diminishing the risk of missed diagnosis and misdiagnosis.

Interferon stimulated gene 15 (ISG15) modulates phenotype of vascular smooth muscle cells and pathological vascular remodeling.

Introduction: Inflammation is a major determinant of abdominal aortic aneurysms (AAA). Interferon stimulated gene 15 (ISG15) has a role in vascular remodelling in AAA. This study investigates the mechanisms whereby ISG15 might affect vascular remodeling and function.

Comprehensive analysis of relapsed-refractory mature B-cell non-Hodgkin lymphoma in children and adolescents.

The outcome of B-cell non-Hodgkin lymphoma (B-NHL) in children and adolescents has improved significantly over recent decades due to risk-adapted strategies and the use of immunotherapy. However, refractory or relapsed (R/R) B-NHL remains extremely difficult to cure (<30%). This retrospective study of 45 patients with R/R B-NHL reflects the limited benefit associated with reintroducing rituximab in second-line strategies, the importance of achieving complete remission before stem cell transplantation and the potential role of TP53 as a biomarker in R/R B-NHL.

Could microRNA Analysis Help in the Management of Medullary Thyroid Cancer?

In medullary thyroid carcinoma (MTC), calcitonin levels and TNM staging are established prognostic factors. However, the diagnostic accuracy of cytology in MTC is poor. In this context, microRNAs (miRNAs) may be useful as valuable biomarkers, although evidence in MTC remains scarce.

Nutritional status and quality of life of patients with advanced gastroenteropancreatic neuroendocrine neoplasms in Spain: the NUTRIGETNE (GETNE-S2109) study.

Patients with advanced gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) have impaired nutritional and physical performance due to the cancer pathophysiology and its treatment. The NUTRIGETNE study sought to characterize the nutritional status of patients with advanced GEP-NENs in Spain. This is a cross-sectional study that included patients with advanced GEP-NENs receiving active oncological treatment.

Analysis of Maternity Rights Perception: Impact of Maternal Care in Diverse Socio-Health Contexts.

Maternity rights are perceived and fulfilled differently according to women's psychosocial characteristics, leading to varying maternal experiences and outcomes. It is necessary to know the impact of cultural context, emotional well-being, and resource availability on the maternal woman's clinical care experience. The aim is to identify if these factors contribute to disparities in the perception of maternity rights fulfillment in Spain and Colombia.

Characterization of Inactive COPD Patients: Barriers to Physical Activity and Perceived Impact of Inactivity.

Backcround: Chronic obstructive pulmonary disease (COPD) is characterized by high morbidity and mortality, with physical inactivity being a major contributor to poor outcomes. This study aims to identify subgroups of inactive COPD patients by analyzing reported barriers to physical activity and the perceived impact of inactivity on their disease.

Methods: In 91 consecutive stable COPD patients, physical activity was measured using a SenseWear armband and the SAQ-COPD questionnaire, to define inactivity as a physical activity level <1.

Neutrophil-to-lymphocyte ratio is associated with accelerometer-measured physical activity levels in breast cancer survivors.

Introduction: Physical activity (PA) has been associated with remarkable benefits in breast cancer (BC) survivors. However, the physiological mechanisms that underlie these benefits are not well understood and the published results are inconsistent and weak. Some authors suggest that some biomarkers, particularly those related with inflammation, insulin resistance, or sexual hormones may account for some of these benefits.

Single-Cell RNA Sequencing on Formalin-Fixed and Paraffin-Embedded (FFPE) Tissue Identified Multi-Ciliary Cells in Breast Cancer.

The purpose of this study was to evaluate the suitability of formalin-fixed and paraffin-embedded (FFPE) samples and fixed fresh (FF) samples for single-cell RNA sequencing (scRNAseq). To this end, we compared single-cell profiles from FFPE and matched FF tissue samples of one invasive carcinoma of no special type carcinoma (invasive ductal carcinoma-IDC) and one invasive lobular carcinoma (ILC) to assess consistency in cell type distribution and molecular profiles. The results were validated using immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), and electron microscopy.

Lipoxin A levels correlate with severity in a Spanish COVID-19 cohort: potential use of endogenous pro-resolving mediators as biomarkers.

Background: SARS-CoV-2, the causative virus of the COVID-19 global pandemic, leads to a wide variety of responses among patients. Some of them present a very severe phenotype, while others only experience mild symptoms or are even asymptomatic. This differential prognosis is tightly related to the inflammatory status of the patient.

Regulated microbe vaccines: from concept to (pre-clinical) reduction to practice.

Introduction: Vaccines to prevent important infections involving, e.g. influenza viruses, severe acute respiratory syndrome-causing coronaviruses (e.

Recommendations for the diagnosis and treatment of anti-neutrophil cytoplasmic autoantibody associated vasculitis.

Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is characterised by small vessel necrotising inflammatory vasculitis. Prior to immunosupressant therapy availability it usually led to a fatal outcome. Current treatment has changed ANCA-associated vasculitis into a condition with a significant response rate, although with a not negligible relapse occurrence and cumulative organ lesions, mostly due to drug-related toxicities.

Improving Anxiety Related to Chronic Pain Through a Sleep Circadian Intervention Program: A Pilot Study.

The limitations of pharmacological treatments for chronic pain have become increasingly evident: dependency, side effects, resistance, and diminishing efficacy. The urgent need for innovative solutions has become a compelling focus for improving patient outcomes. Innovative non-pharmacological approaches, such as sleep management, as a strategy to reduce opioid consumption and pain control are needed.

Design: Prospective, quadruple-blind, multicentre, randomised, controlled trial.

Shaping current European mitochondrial haplogroup frequency in response to infection: the case of SARS-CoV-2 severity.

The frequency of mitochondrial DNA haplogroups (mtDNA-HG) in humans is known to be shaped by migration and repopulation. Mounting evidence indicates that mtDNA-HG are not phenotypically neutral, and selection may contribute to its distribution. Haplogroup H, the most abundant in Europe, improved survival in sepsis.

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.

Best clinical model predicting extubation failure: a diagnostic accuracy post hoc analysis.

Purpose: Predicting extubation failure remains a clinical challenge. This study aimed to determine diagnostic accuracy of models used at the bed side.

Methods: Post hoc analysis of 2341 patients at all risk included in five multicenter randomized trials.

Circulating PD-1hi CXCR5- and CXCR5+ CD4 T cells are elevated in patients with newly diagnosed Giant Cell Arteritis and predict relapse.

Objectives: Giant cell arteritis (GCA) is a large/medium-vessel granulomatous vasculitis, and the PD-1/PD-L1 coinhibitory pathway seems to be implicated in its pathogenesis. CD4 T cells expressing high PD-1 levels, CD4+CXCR5-PD-1hi peripheral helper (Tph) and CD4+CXCR5+PD-1hi follicular helper T cells (Tfh), are key mediators of autoimmunity. Their frequencies are elevated in the peripheral blood of subjects with several autoimmune conditions but have not been investigated in GCA.

The role of rapid multiplex molecular syndromic panels in the clinical management of infections in critically ill patients: an experts-opinion document.

Rapid multiplex molecular syndromic panels (RMMSP) (3 or more pathogens and time-to-results < 6 h) allow simultaneous detection of multiple pathogens and genotypic resistance markers. Their implementation has revolutionized the clinical landscape by significantly enhancing diagnostic accuracy and reducing time-to-results in different critical conditions. The current revision is a comprehensive but not systematic review of the literature.

Deciphering long-term immune effects of HIV-1/SARS-CoV-2 co-infection: a longitudinal study.

Introduction: While the general immune response to Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) is well-understood, the long-term effects of Human Immunodeficiency Virus-1/Severe Acute Respiratory Syndrome-Coronavirus-2 (HIV-1/SARS-CoV-2) co-infection on the immune system remain unclear. This study investigates the immune response in people with HIV-1 (PWH) co-infected with SARS-CoV-2 to understand its long-term health consequences.

Methods: A retrospective longitudinal study of PWH with suppressed viral load and SARS-CoV-2 infection was conducted.

Patient Blood Management: A conceptual and analytical vision from the leadership in Spain.

The evolution of blood saving programs to Patient Blood Management (PBM) represents a broader and more comprehensive approach to optimize the use of the patient's own blood, thus improving clinical outcomes and minimizing the risks associated with allogeneic blood transfusion with a holistic view of socio-economic sustainability. Implementing the strategies of the three PBM pillars in any hospital center involves a transversal change throughout the organization in which it can be very useful to apply the strategy defined by Kotter at the business level for change management. The support of renowned institutions such as the World Health Organization and the European Commission demonstrates the importance and urgency of implementing PBM programs, setting guidelines at an international level and supporting the adoption of effective strategies in the management of blood transfusion at a national and institutional level.
