Summary
New diagnostic criteria for hemodynamic orthostatic dizziness/vertigo are proposed to aid clinicians. These criteria help differentiate global brain hypoperfusion from other causes of dizziness.
Area of Science:
- Neurology
- Otolaryngology
- Cardiology
Background:
- Orthostatic dizziness/vertigo lacks standardized diagnostic criteria.
- Distinguishing hemodynamic causes from other etiologies is clinically challenging.
Purpose of the Study:
- To establish diagnostic criteria for hemodynamic orthostatic dizziness/vertigo for the International Classification of Vestibular Disorders (ICVD).
- To provide clinicians with clear terminology and diagnostic guidance.
Main Methods:
- Expert consensus derived from an extensive review of 90 years of research.
- Inclusion of specific diagnostic requirements for definite and probable cases.
- Emphasis on orthostatic blood pressure and heart rate measurements.
Main Results:
- Defined criteria for hemodynamic orthostatic dizziness/vertigo, including symptom frequency, triggers, and subsidence.
- Established criteria for probable hemodynamic orthostatic dizziness/vertigo with associated symptoms.
- Highlighted the importance of orthostatic hypotension, postural tachycardia syndrome, or syncope.
Conclusions:
- The proposed criteria aim to improve the understanding and diagnosis of hemodynamic orthostatic dizziness/vertigo.
- Standardized criteria will aid in differentiating global brain hypoperfusion-related dizziness.
- Accurate diagnosis is crucial for appropriate clinical management and research.

01:28Criteria for Causality: Bradford Hill Criteria - II
1.2K
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

01:25Yield Criteria for Ductile Materials under Plane Stress
521
In designing structural elements and machine parts using ductile materials, it is crucial to ensure that these components withstand applied stresses without yielding. Yielding is initially determined through a tensile test, which evaluates the material's response to uniaxial stress. However, tensile stress is insufficient when components face biaxial or plane stress conditions This condition requires advanced criteria to predict failure.

Like benzene, cyclobutadiene and cyclooctatetraene are cyclic compounds with alternate single and double bonds. However, their chemical behavior differs from benzene, as they are unstable and not aromatic. So, what are the structural characteristics of unsaturated compounds categorized as aromatic?
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n +...
