Cortical Tau Aggregation Patterns Associated With Apraxia in Patients With Alzheimer Disease.

Background And Objectives: Apraxia is a frequently observed symptom in Alzheimer disease (AD), but the causal pathomechanism underlying this dysfunction is not well understood. Previous studies have demonstrated associations between various cognitive dysfunctions in AD and cortical tau deposition in specific brain areas, suggesting a causal relationship. Thus, we hypothesized that specific regional patterns of tau pathology in praxis-related brain regions may be associated with apraxic deficits in AD.

Cortical Tau Aggregation Patterns associated with Apraxia in Alzheimer's Disease.

Objectives: Apraxia is a core feature of Alzheimer's disease, but the pathomechanism of this characteristic symptom is not well understood. Here, we systematically investigated apraxia profiles in a well-defined group of patients with Alzheimer's disease (AD; N=32) who additionally underwent PET imaging with the second-generation tau PET tracer [18F]PI-2620. We hypothesized that specific patterns of tau pathology might be related to apraxic deficits.

Early diagnostic clues of mucolipidosis type II: Significance of radiological findings.

Mucolipidosis type-II (ML-II) is an ultra-rare disorder caused by deficiency of N-acetylglucosaminyl-1-phosphotransferase enzyme due to biallelic pathogenic variants in GNPTAB gene. There are a few known about the natural history of ML-II. In this study, we presented the natural course of 24 patients diagnosed with ML-II.

Actions speak louder than words: Home visits and its effect on dietary adherence in patients with phenylketonuria.

Aim: Phenylketonuria (PKU) is an inherited metabolic disorder in which accumulation of phenylalanine (Phe) leads to poor neurological outcomes without treatment. Dietary therapy is the main treatment and nonadherence is associated with elevated blood Phe levels and correspondingly poor neuropsychiatric outcomes. This study aimed to examine the effect of home visits on blood Phe levels in PKU patients.

Expanding the phenotypic landscape of Gaucher disease type 3c with a novel entity - Transient neonatal cholestasis.

Gaucher disease (GD) is the most frequent lysosomal storage disorder due to biallelic pathogenic variants in GBA gene. Only homozygous D409H variant has been associated with the cardiovascular phenotype which is also known as Gaucher disease type 3c. In this descriptive study, we presented phenotypic heterogeneity and a novel clinical finding among 13 patients with GD type 3c.

Evaluation of bone health in patients with mucopolysaccharidosis.

Introduction: This study aimed to evaluate the relationship between clinical findings, height and weight standard deviation scores, 25-hydroxyvitamin D (25(OH)D) level, and dual-energy X-ray absorptiometry (DXA) results in patients diagnosed with mucopolysaccharidosis (MPS), where effective current treatments such as enzyme replacement therapy (ERT) can be accessed.

Materials And Methods: 25(OH)D level was measured in 126 patients with MPS (17 with MPS I, 14 with MPS II, 18 with MPS III, 33 with MPS IVA, and 44 with MPS VI; 24-524 months). DXA was performed in 45 of these patients (8 with MPS I, 4 with MPS II, 4 with MPS III, 12 with MPS IVA, and 17 with MPS VI; 62-197 months; all patients were under 18 when DXA was performed) to assess bone mineral density (BMD) of the lumbar spine.

Glycogen storage disease type XII; an ultra rare cause of hemolytic anemia and rhabdomyolysis: one new case report.

Objectives: Aldolase A deficiency also known as glycogen storage disease (GSD) XII, is an ultra rare autosomal recessively inherited GSD, associated with hemolytic anemia and rhabdomyolysis.

Case Presentation: Here, we first report a patient with dermatological findings, hemodialysis requirement for rhabdomyolysis, and a novel likely pathogenic c.971C>T (p.

Antimicrobial efficacy of alternative compounds for use in oral care toward biofilms from caries-associated bacteria in vitro.

For caries-active patients, antimicrobial measures may be useful in addition to mechanical biofilm removal. The aim of this study was to investigate the antimicrobial efficacy of alternative compounds for use in oral care from two main categories (i.e.

Neoascarophis macrouri n. sp. (Nematoda: Cystidicolidae) from the stomach of Macrourus berglax (Macrouridae) in the eastern Greenland Sea.

A new species of parasitic nematode, Neoascarophis macrouri n. sp. (Cystidicolidae), is described from the stomach and stomach wall of the marine deep-water fish Macrourus berglax (onion-eye grenadier) in the eastern Greenland Sea (North Atlantic Ocean).
