Lewy bodies and neurofibrillary tangles, composed of α-synuclein (α-syn) and tau, respectively, often are found together in the same brain and correlate with worsening cognition. Human postmortem studies show colocalization of α-syn and tau occurs in Lewy bodies, but with limited effort to quantify colocalization. In this study, postmortem middle temporal gyrus tissue from decedents (n = 9) without temporal lobe disease (control) or with Lewy body disease (LBD) was immunofluorescently labeled with antibodies to phosphorylated α-syn (p-α-syn), tau phosphorylated at Ser202/Thr205 (p-tau), or exposure of tau's phosphatase-activating domain (PAD-tau) as a marker of early tau aggregates.

Background: Low-grade fibromyxoid sarcoma is a rare soft tissue tumor characterized by a benign histological appearance but with a high potential for recurrence and metastasis. First described by Evans in 1987, recurrence and metastasis can occur decades after the initial diagnosis, complicating long-term management.
Case Presentation: We report the case of an 83-year-old Jewish female patient diagnosed with low-grade fibromyxoid sarcoma in her right shoulder.
From diagnosis to treatment: exploring the mechanisms underlying optic neuritis in multiple sclerosis.

Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system, commonly causing sensory disturbances, motor weakness, impaired gait, incoordination and optic neuritis (ON). According to the statistics, up to 50% of MS patients experience vision problems during the disease course, suffering from blurred vision, pain, color vision deficits, and even blindness. Treatments have progressed from corticosteroids to therapies targeted against B/T cells.

Advances in sequencing technologies are reshaping clinical diagnostics, prompting the development of new software tools to decipher big data. To this end, we developed functional genomic imaging (FGI), a visualization tool designed to assist clinicians in interpreting RNA-Seq results from patient samples. FGI uses weighted gene co-expression network analysis (WGCNA), followed by a modified Phenograph clustering algorithm to identify co-expression gene clusters.

Department of Pediatrics and Child Health, Faculty of Medicine and Health Sciences, Stellenbosch University, Cape Town, South Africa.
Background And Objectives: Healthcare-associated infections (HAI) are a leading contributor to morbidity and mortality in hospitalised neonates. Diagnosing neonatal HAI is challenging owing to non-specific symptoms and lack of definitive diagnostic markers, contributing to high rates of inappropriate antibiotic use. This study evaluated the theoretical impact of implementing a bedside tool for decision-making on antibiotic length of therapy (LOT).
