Parkinsonian syndromes are considered clinicopathological conditions that are challenging to diagnose. Molecular imaging with [18F]-FDOPA and [18F]-FDG contributes to a more accurate clinical diagnosis by evaluating presynaptic dopaminergic pathways and glucose metabolism, respectively. The aim of this study was to correlate diagnoses made from dual PET/CT with the initial clinical diagnoses, as well as during follow-ups in patients with Parkinsonian syndromes.

The Coanda effect is a fluid dynamics phenomenon in which a fluid jet adheres to a convex or flat surface. This effect occurs when a liquid or gas jet emerging from an orifice clings to an adjacent surface and entrains the surrounding fluid, creating a lower-pressure region along its path that maintains its attachment to the surface. The Coanda effect accounts for the behavior of blood flow in the fetal right atrium and the dispersion of eccentric mitral regurgitation jets along atrial walls.

Background: Experimental models of neurocysticercosis (NCC) are helpful for an improved understanding of the pathophysiological mechanisms of human diseases and for testing novel therapeutic approaches. Controlling inflammation without reducing the effectiveness of anthelmintics is an important challenge in treating neurocysticercosis. This study investigates the effects of currently used drugs (Albendazole and Dexamethasone) in treating murine extraparenchymal NCC.

Introduction: Traumatic memories (TM) are a core feature of stress-related disorders, including posttraumatic stress disorder (PTSD). Treatment is often difficult, and specific pharmacological interventions are lacking. We present a novel non-pharmacological intervention called motor interference therapy (MIT) as a promising alternative for these symptoms.

N-of-1 trials in epilepsy: A systematic review and lessons paving the way forward.

Epilepsia

November 2024

(Affiliated) member or collaborating partner of the European Reference Network (ERN) for rare and complex epilepsies (EpiCARE), Barcelona, Spain.

Article Synopsis
  • N-of-1 trials are single-patient studies that focus on individual responses to treatments, particularly useful for patients with rare forms of epilepsy where larger clinical trials are hard to conduct.
  • A systematic review analyzed such trials to evaluate their design, outcomes, and biases, revealing strong individual treatment customization but also some reporting limitations.
  • The findings highlight the potential of N-of-1 trials to provide valuable insights for treating epilepsy, suggesting a need for improved reporting and methodology in future studies.

  • Terson syndrome is marked by intraocular hemorrhage related to brain injuries, with a notable incidence of 10-40% following sub-arachnoid hemorrhage.
  • A case study of a 48-year-old woman with sub-arachnoid hemorrhage showed significant visual impairment due to vitreous hemorrhage, which improved after treating an aneurysm in a major artery.
  • Timely ophthalmic evaluations are crucial for diagnosing Terson syndrome in patients with sub-arachnoid hemorrhage, as early intervention can help prevent permanent visual loss.

Cranial retained surgical sponges, known as "gossypiboma" or "textiloma", represent a rare but potentially severe complication following surgical procedures. While it is infrequent, it poses a significant risk, particularly in delicate surgical settings such as neurosurgery. The inadvertent retention of cotton balls or surgical gauzes may cause localized inflammation, infection, abscess, or neurologic sequelae.

Multiple sclerosis (MS) is a chronic inflammatory autoimmune neurological disease characterized by the recurrent appearance of demyelinating lesions and progressive disability. Currently, there are multiple disease-modifying treatments, however, there is a significant need to develop new therapeutic targets, especially for the progressive forms of the disease. This review article provides an overview of the most recent studies aimed at understanding the inflammatory processes that are activated in response to the accumulation of kynurenine pathway (KP) metabolites, which exacerbate an imbalance between immune system cells (e.

Background: The serum levels of presepsin correlate with parameters indicating cholestasis in sepsis; however, the probability and significance of this association remain uncertain. We aimed to ascertain whether infection, as signaled by presepsin levels, is the primary determinant of elevated biliary parameters in sepsis.

Methods: A unicenter, retrospective study included 396 COVID-free emergency-admitted patients, in which presepsin level was determined.

  • The world is facing an aging population with increased feelings of loneliness, especially in older individuals with mild neurocognitive disorders; functional impairment in daily activities plays a significant role in this.
  • A study conducted from February to December 2023 examined the connections between loneliness, depression, daily living deficits, and cognitive symptoms in older adults, involving interviews and established scales to measure these factors.
  • Results showed that 30% of participants experienced moderate to high loneliness levels, and loneliness was linked to depression and lower daily living skills, highlighting the importance of addressing these issues to improve overall health and well-being in older adults.

Intraoperative magnetic resonance imaging (iMRI) has witnessed significant growth in the field of neurosurgery, particularly in glioma surgery, enhancing image-guided neuronavigation and optimizing the extent of resection (EOR). Despite its extensive use in the treatment of gliomas, its utility in brain metastases (BMs) remains unexplored. This study examined the effect of iMRI on BM resection.

Epidemiological studies and meta-analyses have shown a strong association between high seroprevalence of () and schizophrenia. Schizophrenic patients showed higher levels of anti-Toxoplasma immunoglobulins M and G (IgM and IgG) when compared to healthy controls. Previously, in a rat model, we demonstrated that the progeny of mothers immunized with lysates before gestation had behavioral and social impairments during adulthood.

Acoustic, lexical, and syntactic information are simultaneously processed in the brain requiring complex strategies to distinguish their electrophysiological activity. Capitalizing on previous works that factor out acoustic information, we could concentrate on the lexical and syntactic contribution to language processing by testing competing statistical models. We exploited electroencephalographic recordings and compared different surprisal models selectively involving lexical information, part of speech, or syntactic structures in various combinations.

Introduction: Lipopolysaccharide-responsive and beige-like anchor (LRBA) is a scaffolding protein that interacts with proteins such as CTLA-4 and PKA, the importance of which has been determined in various cell types, including T regulatory cells, B cells, and renal cells. LRBA deficiency is associated with an inborn error in immunity characterized by immunodeficiency and autoimmunity. In addition to defects in T regulatory cells, patients with LRBA deficiency also exhibit B cell defects, such as reduced cell number, low memory B cells, hypogammaglobulinemia, impaired B cell proliferation, and increased autophagy.
