Objective: The aim of the present study was to determine the test-retest reliability of the angle of subjective verticality in healthy young persons.
Methods: The participants were ten young healthy adults, five men and five women. The subjective postural vertical (SPV) was measured in the frontal plane (with eyes open and eyes closed) and in the sagittal plane (with eyes closed). Participants were retested 1 week after the first test. The test-retest reliability for each parameter was estimated using the intra-class correlation coefficient [ICC(1,1)], and the minimal detectable change (MDC) scores were established with a confidence level of 95%.
Results: The test-retest reliability for the SPV was substantial (ICC ≥0.61). The MDC values of the SPVs ranged from 1.1° to 2.1°.
Conclusions: The test-retest reliability of the postural vertical in the frontal and sagittal planes was sufficiently high in healthy young participants.

Posttranslational modifications (PTMs) of proteins play critical roles in regulating many cellular events. Antibodies targeting site-specific PTMs are essential tools for detecting and enriching PTMs at sites of interest. However, fundamental difficulties in molecular recognition of both PTM and surrounding peptide sequence have hindered the efficient generation of highly sequence-specific anti-PTM antibodies.

Background: The COVID-19 pandemic has accelerated the digitalization of modern society, extending digital transformation to daily life and psychological evaluation and treatment. However, the development of competencies and literacy in handling digital technology has not kept pace, resulting in a significant disparity among individuals. Existing measurements of digital literacy were developed before widespread information and communications technology device adoption, mainly focusing on one's perceptions of their proficiency and the utility of device operation.

Background: Vestibular schwannoma (VS) is a common intracranial tumor that affects patients' quality of life. Reliable imaging techniques for tumor volume assessment are essential for guiding management decisions. The study aimed to compare the ABC/2 method to the gold standard planimetry method for volumetric assessment of VS.

Validating the Fluctuating Mental Status Evaluation in Neurocritically Ill Patients With Acute Stroke.

Objectives: Neurocritically ill patients are at high risk for developing delirium, which can worsen the long-term outcomes of this vulnerable population. However, existing delirium assessment tools do not account for neurologic deficits that often interfere with conventional testing and are therefore unreliable in neurocritically ill patients. We aimed to determine the accuracy and predictive validity of the Fluctuating Mental Status Evaluation (FMSE), a novel delirium screening tool developed specifically for neurocritically ill patients.
