Comparative Clinical Study on Magnesium Absorption and Side Effects After Oral Intake of Microencapsulated Magnesium (MAGSHAPE Microcapsules) Versus Other Magnesium Sources.

Background/objectives: Magnesium (Mg)-based food supplements contribute to the maintenance of adequate levels of Mg that are essential for overall health and well-being. The aim of this double-blind, randomized, cross-over clinical study was to assess the plasma Mg levels in volunteers following the oral administration of a magnesium-based nutraceutical ingredient, MAGSHAPE microcapsules (Mg-MS), in comparison to other commonly used magnesium sources, including the following: Mg Oxide (MgO), Mg Citrate (Mg-C), and Mg bisglycinate (Mg-BG).

Methods: A total of 40 healthy women and men were put on a low-Mg diet for 7 days, and after 8 h of fasting, a blood sample was taken from a digital puncture before (0 h) and 1 h, 4 h, and 6 h after the oral intake of each product.

The Value of Bone Marrow Assessment by FDG PET/CT, Biopsy and Aspirate in the Upfront Evaluation of Mantle Cell Lymphoma: A Nationwide Cohort Study.

Background: Assessment of bone marrow infiltration (BMI) is part of the initial staging of mantle cell lymphoma (MCL), although BMI evaluated by biopsy (BMB) is not considered significant in the MIPI scales, and standardized recommendations remain lacking.

Objectives: To evaluate the accuracy and prognostic impact of BMI assessed by PET/CT and BMB in a large series of MCL patients.

Methods: We deconstructed the IPI-NCCN, MIPI, and MIPI-c indices and considered BMI as positive if indicated by a BMB, PET/CT scan, or a combination of both.

Birth weight and head circumference for 22-29 weeks gestation neonates from an international cohort.

Objective: Size at birth is a key indicator of in utero growth. Our objective was to generate sex-specific percentiles for birth weight and head circumference in neonates born between 22 and 29 weeks gestation from pregnancies without hypertension or diabetes and assess differences between vaginal and caesarean births and between singletons and twins.

Methods: We used data from 12 countries participating in the International Network for Evaluating Outcomes in Neonates database from 2007 to 2021.

Pelvic Ring Reconstruction with an Osteocutaneous Fibula Flap for Abdominal Wall Repair in Adults with Bladder Exstrophy.

Abdominal wall repair in adults with bladder exstrophy is challenging. We present a case of a 46-year-old woman with bladder exstrophy presenting with a large midline incisional hernia associated with a 13-cm hypoplasia of both pubic rami that precluded fixation of any abdominal mesh. A two-stage approach was adopted.

Kir2.1 mutations differentially increase the risk of flecainide proarrhythmia in Andersen Tawil Syndrome.

Background: Flecainide and other class-Ic antiarrhythmic drugs (AADs) are widely used in Andersen-Tawil syndrome type 1 (ATS1) patients. However, class-Ic drugs might be proarrhythmic in some cases. We investigated the molecular mechanisms of class-I AADs proarrhythmia and whether they might increase the risk of death in ATS1 patients with structurally normal hearts.

Post-transplant relapse in pediatric acute lymphoblastic leukemia in the era of CAR-T cell therapy. A multicenter analysis of Grupo Español de Trasplante Hematopoyetico y Terapia Celular (GETH-TC) Pediatric Committee.

Background: The management of relapsed acute lymphoblastic leukemia (ALL) after hematopoietic stem cell transplantation (HSCT) has evolved significantly. Initially, treatment options were limited to palliative care, salvage chemotherapy, and second HSCT. Currently, the focus has shifted to innovative immunotherapies, particularly CAR T-cell therapy.

Dynamic 18 F-FDG PET to detect differences among patients with progressive and relapsing multiple sclerosis: a pilot study.

Background: Patients with multiple sclerosis (MS) may remain in a relapsing-remitting (RRMS) course despite long-standing disease, while others will develop secondary progression (SPMS). Chronic inflammation and changes in the blood-brain barrier resulting in perturbed glucose metabolism may account for these differences. PET-MRI with kinetic analysis of 2-deoxy-2(18 F)fluoro-d-glucose (18 F-FDG) provides insight into glucose metabolism and has proven useful in several chronic inflammatory diseases.

Associations between antidiabetic medications and cerebrospinal fluid biomarkers of Alzheimer's disease.

Background: It has been hypothesized that insulin resistance is pivotal in mediating amyloid and tau dysregulations in Alzheimer's disease (AD).

Objective: To investigate the impact of different antidiabetic agents, their daily dosage intake, and treatment duration on cerebrospinal fluid (CSF) AD biomarkers among patients with type 2 diabetes.

Methods: This cross-sectional study selected patients between 50 and 80 years with diabetes and CSF AD biomarkers screened between 2017 and 2023 in the VALCODIS Cohort.

Increased EBNA1-specific antibody response in primary-progressive multiple sclerosis.

Background And Objectives: The impact of viral infections on disease susceptibility and progression has predominantly been studied in patients with relapse-onset MS (RMS). Here, we determined immune responses to ubiquitous viruses in patients with primary progressive MS (PPMS).

Methods: Antibody responses to Epstein-Barr virus (EBV), specifically to the latent EBV nuclear antigen 1 and the lytic viral capsid antigen VCA, human herpesvirus 6 (HHV-6), human cytomegalovirus (HCMV), and measles virus were determined in a cohort of 68 PPMS patients with a mean follow-up of 8 years and compared with 66 healthy controls matched for sex and age.

Emerging role of circulating piRNAs in the diagnosis of heart transplant rejection.

Background: Liquid biopsy offers a potential alternative to decrease or eliminate endomyocardial biopsy for diagnosing allograft rejection. p-element-induced wimpy testis-interacting RNAs (piRNAs) are novel and promising disease biomarkers for their intrinsic characteristics such as stability in body fluids; however, their role in allograft rejection remains unexplored.

Methods: A training set based on small RNA sequencing technology was performed to identify piRNAs in endomyocardial tissue (n = 8) and serum samples (n = 40) from patients following heart transplantation.

Modulatory effects of CNNM4 on protein- l -isoaspartyl- O -methyltransferase repair function during alcohol-induced hepatic damage.

Background And Aims: Alcohol-associated liver disease (ALD) is a leading cause of liver-related mortality worldwide, with limited treatment options beyond abstinence and liver transplantation. Chronic alcohol consumption has been linked to magnesium (Mg 2+ ) deficiency, which can influence liver disease progression. The mechanisms underlying Mg 2+ homeostasis dysregulation in ALD remain elusive.

MRgFUS subthalamotomy in Parkinson's disease: an approach aimed at minimizing Lesion Volume.

Idiopathic Parkinson's Disease (PD) is a neurodegenerative disorder characterized by tremor, rigidity, bradykinesia, and postural instability. Magnetic Resonance-guided high-intensity focused ultrasound (MRgFUS) of the subthalamic nucleus (STN) is gaining recognition as a minimally invasive surgical option. This study assesses the safety and efficacy of unilateral MRgFUS subthalamotomy, aiming to create the smallest effective lesion.

Ecological study to estimate the prevalence of patients with acid sphingomyelinase deficiency in Spain. PREVASMD study.

Material And Methods: PREVASMD was a descriptive, multicenter, and ecological study involving 21 physicians from different specialties (mainly Internal Medicine, Paediatrics and Hematology), of different autonomous communities, with experience in ASMD management.

Early Metabolomic Profiling as a Predictor of Renal Function Six Months After Kidney Transplantation.

Background: Kidney transplantation is the therapy of choice for patients with advanced chronic kidney disease; however, predicting graft outcomes remains a significant challenge. Early identification of reliable biomarkers could enhance post-transplant management and improve long-term outcomes. This study aimed to identify metabolomic biomarkers within the first week after kidney transplantation that predict renal function at six months.

Recipient-Donor Sex Constellation in Liver Transplantation for Hepatocellular Carcinoma-An ELTR Study.

Background & Aims: Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Liver transplantation (LT) is a curative treatment option. We investigated survival outcomes based on recipient-donor sex constellation (RDSC) following LT.

Validation of urine p-cresol glucuronide as renal cell carcinoma non-invasive biomarker.

Renal cell carcinoma (RCC) stands among the most lethal urological malignancies. Most RCCs are incidentally diagnosed as initial symptoms are unspecific. Novel, minimally-invasive diagnostic and prognostic methods for RCC are needed, ideally in urine.

Incidence of post-acute COVID-19 symptoms across healthcare settings in seven countries: an international retrospective cohort study using routinely-collected data.

Background: The World Health Organisation (WHO) has identified a range of symptomatic manifestations to aid in the clinical diagnosis of post-COVID conditions, herein referred to as post-acute COVID-19 symptoms. We conducted an international network cohort study to estimate the burden of these symptoms in North American, European, and Asian populations.

Methods: A federated analysis was conducted including 10 databases from the United Kingdom, Netherlands, Norway, Estonia, Spain, France, South Korea, and the United States, between September 1st 2020 and latest data availability (which varied from December 31st 2021 to February 28th 2023), covering primary and secondary care, nationwide registries, and claims data, all mapped to the Observational Medical Outcomes Partnership Common Data Model (OMOP CDM).

Clinical trajectories of patients with multiple sclerosis from onset and their relationship with serum neurofilament light chain levels.

Background: Serum neurofilament light chain (sNfL) is a biomarker of neuroaxonal destruction that correlates with acute inflammation (AI) in multiple sclerosis (MS). However, in the treatment era, progression without AI is the main driver of long-term disability. sNfL may provide added value in detecting ongoing axonal damage and neurological worsening in patients without AI.

Cost-Utility of Real-Time Continuous Glucose Monitoring versus Self-Monitoring of Blood Glucose in People with Insulin-Treated Type 2 Diabetes in Spain.

Objective: Management of advanced type 2 diabetes (T2D) typically involves daily insulin therapy alongside frequent blood glucose monitoring, as treatments such as oral antidiabetic agents are therapeutically insufficient. Real-time continuous glucose monitoring (rt-CGM) has been shown to facilitate greater reductions in glycated hemoglobin (HbA1c) levels and improvements in patient satisfaction relative to self-monitoring of blood glucose (SMBG). This study aimed to investigate the cost-utility of rt-CGM versus SMBG in Spanish patients with insulin-treated T2D.
