Native vitamin D in CKD and renal transplantation: meaning and rationale for its supplementation.

Chronic kidney disease (CKD) poses a significant epidemiological challenge, necessitating effective patient management strategies. Nutritional intervention, particularly vitamin D supplementation, has garnered attention for its potential therapeutic utility in CKD. Despite widespread acknowledgment of the importance of vitamin D, particularly in bone and mineral metabolism, its supplementation in CKD patients for non-skeletal purposes remains contentious due to limited evidence.

Low Levels of Cortisol are Associated with HIV Infection in Older People: A Hormonal Substudy in the OVER50 Cohort.

Introduction: People with the human immunodeficiency virus (PWH) who were diagnosed long ago are more prone to age-related conditions and comorbidities than the general population. We hypothesized that older PWH have endocrine abnormalities that may influence the patient's health status.

Methods: Mean hormonal values across the thyrotropic, somatotropic, corticotropic, and gonadal axis, and percentage of subjects with abnormal values, were compared between PWH aged ≥50 years (n=30) and people without HIV (n=30) (Over50 cohort).

Impact of gender on in-hospital and long-term outcomes after transcatheter aortic valve implantation: an analysis of the Spanish TAVI registry.

Introduction And Objectives: Impact of gender on long-term outcomes after transcatheter aortic valve implantation (TAVI) remains uncertain. We aimed to investigate gender-specific differences in TAVI and its impact on outcomes.

Methods: This analysis used data from the prospective Spanish TAVI registry, which included consecutive TAVI patients treated in 46 Spanish centers from 2009 to 2021.

Adult outcomes of childhood kidney replacement therapy in Europe from 2008 to 2019: an ERA Registry study.

Background And Hypothesis: Young adults starting kidney replacement therapy (KRT) during childhood and reaching their 18th birthday (i.e. adult survivors of childhood KRT) form a challenging population of interest to nephrologists treating adults, as during this period there will be a transition to adult renal centres.

The impact of analytical treatment interruptions and trial interventions on time to viral re-suppression in people living with HIV restarting ART in cure-related clinical studies: a systematic review and meta-analysis.

Introduction: To assess the effectiveness of novel HIV curative strategies, "cure" trials require periods of closely monitored antiretroviral therapy (ART) analytical treatment interruptions (ATIs). We performed a systematic review and meta-analysis to identify the impact of ATI with or without novel therapeutics in cure-related studies on the time to viral re-suppression following ART restart.

Methods: Medline, Embase and Web of Science databases were searched for human studies involving ATIs from 1 January 2015 till 22 April 2024.

Dopamine Pathway and Parkinson's Risk Variants Are Associated with Levodopa-Induced Dyskinesia.

Background: Levodopa-induced dyskinesia (LID) is a common adverse effect of levodopa, one of the main therapeutics used to treat the motor symptoms of Parkinson's disease (PD). Previous evidence suggests a connection between LID and a disruption of the dopaminergic system as well as genes implicated in PD, including GBA1 and LRRK2.

Objectives: Our goal was to investigate the effects of genetic variants on risk and time to LID.

Transoral robotic parapharyngeal space dissection.

Transoral robotic surgery (TORS) provides a minimally invasive approach to address tumors in selected and challenging anatomical locations. Among the critical areas where TORS demonstrates its prowess is the oropharynx. Oropharyngeal tumors can invade parapharyngeal space (PPS) which contains vital structures such as the carotid artery, internal jugular vein, and cranial nerves IX-XII.

Rationale and design of the artificial intelligence scalable solution for acute myocardial infarction (ASSIST) study.

Background: Acute coronary syndrome (ACS), specifically ST-segment elevation myocardial infarction is a major cause of morbidity and mortality throughout Europe. Diagnosis in the acute setting is mainly based on clinical symptoms and physician's interpretation of an electrocardiogram (ECG), which may be subject to errors. ST-segment elevation is the leading criteria to activate urgent reperfusion therapy, but a clear ST-elevation pattern might not be present in patients with coronary occlusion and ST-segment elevation might be seen in patients with normal coronary arteries.

Circulating biomarkers of myocardial remodelling: current developments and clinical applications.

Myocardial remodelling, entailing cellular and molecular changes in the different components of the cardiac tissue in response to damage, underlies the morphological and structural changes leading to cardiac remodelling, which in turn contributes to cardiac dysfunction and disease progression. Since cardiac tissue is not available for histomolecular diagnosis, surrogate markers are needed for evaluating myocardial remodelling as part of the clinical management of patients with cardiac disease. In this setting, circulating biomarkers, a component of the liquid biopsy, provide a promising approach for the fast, affordable and scalable screening of large numbers of patients, allowing the detection of different pathological features related to myocardial remodelling, aiding in risk stratification and therapy monitoring.

Lower heart rate in patients with acute heart failure: the role of left ventricular ejection fraction.

Background: The clinical impact of heart rate (HR) in heart failure with preserved ejection fraction (HFpEF) is a matter of debate. Among those with HFpEF, chronotropic incompetence (CI) has emerged as a pathophysiological mechanism linked to the severity of the disease. In this study, we sought to evaluate whether admission heart rate in acute heart failure differs along left ventricular ejection fraction (LVEF).

Lamivudine modulates the expression of neurological impairment-related genes and LINE-1 retrotransposons in brain tissues of a Down syndrome mouse model.

Elevated activity of retrotransposons is increasingly recognized to be implicated in a wide range of neurodegenerative and neurodevelopmental diseases, including Down syndrome (DS), which is the most common chromosomal condition causing intellectual disability globally. Previous research by our group has revealed that treatment with lamivudine, a reverse transcriptase inhibitor, improved neurobehavioral phenotypes and completely rescued hippocampal-dependent recognition memory in a DS mouse model, Ts65Dn. We hypothesized that retrotransposition rates would increase in the Ts65Dn mouse model, and lamivudine could block retrotransposons.
