The Calmodulin Binding Transcription Activator 1 (CAMTA1) gene plays a central role in the human nervous system. Here evidence-based perspectives on its clinical value for the screening of CAMTA1 malfunction is provided and argued that in future, patients suffering from brain tumours and/or neurological disorders could benefit from this diagnostic. In neuroblastomas as well as in low-grade gliomas, the influence of reduced expression of CAMTA1 results in opposite prognosis, probably because of different carcinogenic pathways in which CAMTA1 plays different roles, but the exact genetics bases remains unsolved. Rearrangements, mutations and variants of CAMTA1 were associated with human neurodegenerative disorders, while some CAMTA1 single nucleotide polymorphisms were associated with poorer memory in clinical cases and also amyotrophic lateral sclerosis. So far, the follow-up of patients with neurological diseases with alterations in CAMTA1 indicates that defects (expression, mutations, and rearrangements) in CAMTA1 alone are not sufficient to drive carcinogenesis. It is necessary to continue studying CAMTA1 rearrangements and expression in more cases than done by now. To understand the influence of CAMTA1 variants and their role in nervous system tumours and in several psychiatric disorders is currently a challenge.

Acute physical exercise and ambulatory blood pressure in resistant hypertension.
J Hypertens
November 2024
Faculty of Sport Sciences, Universidad Europea de Madrid.
Objectives: The effects of acute physical exercise in patients with resistant hypertension remain largely unexplored compared with hypertensive patients in general. We assessed the short-term effects of acute moderate-intensity (MICE) and high-intensity interval exercise (HIIE) on the clinic (BP) and 24-h ambulatory blood pressure (ABP) of patients with resistant hypertension.
Methods: Using a crossover randomized controlled design, 10 participants (56 ± 7 years) with resistant hypertension performed three experimental sessions: MICE, HIIE, and control.
Progression of Amyloid Accumulation in Late Adulthood Among People With Childhood-Onset Epilepsy.
Neurology
February 2025
Departments of Child Neurology and General Practice, University of Turku and Turku University Hospital, Finland.
Background And Objectives: Previous research has demonstrated increased brain amyloid plaque load in individuals with childhood-onset epilepsy in late middle age. However, the trajectory of this process is not yet known. The aim of this study was to determine whether individuals with a history of childhood-onset epilepsy show progressive brain aging in amyloid accumulation in late adulthood (Turku Adult Childhood-Onset Epilepsy study, TACOE).

MeLis Institute, SynatAc Team, Inserm U1314/ UMR CNRS5284, France.
Background And Objectives: Breast cancers (BCs) of patients with paraneoplastic neurologic syndromes and anti-Yo antibodies (Yo-PNS) overexpress human epidermal growth factor receptor 2 (HER2) and display genetic alterations and overexpression of the Yo-onconeural antigens. They are infiltrated by an unusual proportion of B cells. We investigated whether these features were also observed in patients with PNS and anti-Ri antibodies (Ri-PNS).

Macquarie Medical School, Faculty of Medicine, Health and Human Sciences, Macquarie University, Sydney.
Background And Objectives: Despite the absence of acute lesion activity in multiple sclerosis (MS), chronic neurodegeneration continues to progress, and a potential underlying mechanism could be the kynurenine pathway (KP). Prolonged activation of the KP from chronic inflammation is known to exacerbate the progression of neurodegenerative diseases through the production of neurotoxic metabolites. Among the 8 KP metabolites, six of them, namely kynurenine (KYN), 3-hydroxylkynurenine (3HK), anthranilic acid (AA), kynurenic acid (KYNA), and quinolinic acid (QUIN), have been associated with neurodegeneration.

Neuroimmunology Laboratory and Neuroimmunology Research Section, IRCCS Mondino Foundation, Pavia, Italy.
Background And Objectives: Antibodies to proteolipid protein-1 (PLP1-IgG), a major central myelin protein also expressed in the peripheral nervous system (PNS) as the isoform DM20, have been previously identified mostly in patients with multiple sclerosis (MS), with unclear clinical implications. However, most studies relied on nonconformational immunoassays and included few patients with non-MS CNS autoimmune demyelinating disorders (ADDs). We aimed to investigate conformational PLP1-IgG in the whole ADD spectrum.
