Objective: To screen and evaluate the significance of anticardiolipin seroprevalence in patients with acute ischemic stroke, in patients with infectious disease, and in healthy subjects resident in Sudan, a tropical country endemic for several infectious diseases.
Methods: We conducted the study in Khartoum Teaching Hospital in Khartoum, Sudan between July 2003 and January 2005. We included 89 stroke cases, 30 infectious disease patients, and 30 asymptomatic healthy subjects. We estimated IgG and IgM anticardiolipin antibody titers in serum samples from all subjects in the 3 study categories at the time of hospital admission.
Results: We found a significantly higher prevalence of anticardiolipin antibodies in the stroke and infection groups compared to the healthy subjects. However, there was no significant difference in anticardiolipin seroprevalence between patients with stroke and patients with infectious disease.
Conclusion: Caution is necessary when interpreting the presence of antiphospholipid antibodies as a stroke risk in patients harboring infection or living in places with high endemicity of infectious diseases.

AQP4 antibody-seropositive neuromyelitis optica spectrum disorder in a patient with mixed connective tissue disease: a case report.

Neurology and Stroke Unit, Pescara General Hospital, Pescara, Italy.
Background: Neuromyelitis optica spectrum disorders (NMOSDs) are degenerative diseases frequently associated with severe recurrences and high risk of progressive disability. In this report, we describe an unusual case of a patient with the coexistence between NMOSD and mixed connective tissue disease (MCTD).
Case Description: A 58-year-old Caucasian man was admitted to the Emergency Department (ED) with low back pain and walking inability.

Background: Evidence from preclinical studies suggests that IL-6 signalling has the potential to modulate immunopathogenic mechanisms upstream of autoantibody effector mechanisms in patients with generalised myasthenia gravis. We aimed to assess the safety and efficacy of satralizumab, a humanised monoclonal antibody targeting the IL-6 receptor, in patients with generalised myasthenia gravis.
Methods: LUMINESCE was a randomised, double-blind, placebo-controlled, multicentre, phase 3 study at 105 sites, including hospitals and clinics, globally.

Background: Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study.

Coagulation factors are intrinsically expressed in various brain cells, including astrocytes and microglia. Their interaction with the inflammatory system is important for the well-being of the brain, but they are also crucial in the development of many diseases in the brain such as stroke and traumatic brain injury. The cellular effects of coagulation are mediated mainly by protease-activated receptors.

Context: Thyroid hormones play a crucial role in metabolic regulation and maintaining cardiovascular homeostasis. The Parametric Thyroid Feedback Quantile-based Index (PTFQI) assesses central thyroid hormone sensitivity by standardizing the inverse relationship between free thyroxine (T4) and thyroid-stimulating hormone (TSH).
Objective: To investigate the relationship between PTFQI and cardiovascular risk in the euthyroid Korean population.
