Current and novel biomarkers in cardiogenic shock.

Cardiogenic shock (CS) carries a 30-50% in-hospital mortality rate, with little improvement in outcomes in the last decade. Challenges in improving outcomes are closely linked to the frequent late presentation or diagnosis of CS where the 'point of no return' has often passed, leading to haemodynamic dysregulation, progressive myocardial depression, hypotension, and a downward spiral of hypoperfusion, organ dysfunction and decreasing myocardial function, driven by inflammation and metabolic derangements. Novel therapeutic interventions may have varying efficacy depending on the type and stage of shock in which they are applied.

Evidence suggests that approximately 63.0%-84.2% of stroke survivors have hypertension, yet there is currently no stroke prediction tool specifically designed for individuals with hypertension.

TSE/Prion Biochemistry Section, DIR, National Institute of Allergy and Infectious Diseases (NIAID), Hamilton, Montana, USA.
Background: Cerebrospinal fluid (CSF) α-synuclein seeding activity (SSA) via a seed amplification assay might predict central Lewy body diseases (LBD) in at-risk individuals.
Objective: The aim was to assess CSF SSA in a prospective, longitudinal study.
Methods: Participants self-reported risk factors were genetics, olfactory dysfunction, dream enactment behavior, orthostatic intolerance, or hypotension; individuals who had ≥3 confirmed risk factors underwent CSF sampling and were followed for up to 7.
Simulation of clinical trials of oral treprostinil in pulmonary arterial hypertension using a virtual population.

Challenges in drug development for rare diseases such as pulmonary arterial hypertension can be addressed through the use of mathematical modeling. In this study, a quantitative systems pharmacology model of pulmonary arterial hypertension pathophysiology and pharmacology was used to predict changes in pulmonary vascular resistance and six-minute walk distance in the context of oral treprostinil clinical studies. We generated a virtual population that spanned the range of clinical observations and then calibrated virtual patient-specific weights to match clinical trials.

It is generally accepted that intraocular pressure (IOP) depends on the rate of aqueous humor production, system outflow resistance, and episcleral venous pressure. Therefore, control IOP values are expected to be within the strict and predictable limits in specific animal species, and there should be no vast differences between species. However, in the literature the control IOP values significantly vary (from potentially "hypotensive" to "hypertensive") within the same species, and especially between species depending on the measurement technique, head position in relation to the rest of the body, circadian rhythm, age, and topical and systemic drugs (anesthetics) applied.
