Norepinephrine Infusion and the Central Venous Waveform in a Porcine Model of Endotoxemic Hypotension with Resuscitation: A Large Animal Study.

Background: Venous waveform analysis is an emerging technique to estimate intravascular fluid status by fast Fourier transform deconvolution. Fluid status has been shown proportional to , the amplitude of the fundamental frequency of the waveform's cardiac wave upon deconvolution. Using a porcine model of distributive shock and fluid resuscitation, we sought to determine the influence of norepinephrine on of the central venous waveform.

The growing burden of metabolic disorders manifested by hypertension, type 2 diabetes mellitus, hyperlipidemia, obesity and non-alcoholic fatty liver disease presents a significant global health challenge by contributing to cardiovascular diseases and high mortality rates. Β-blockers are among the most widely used drugs in the treatment of hypertension and acute cardiovascular events. In addition to blocking the receptor sites for catecholamines, third-generation β-blockers with associated vasodilating properties, such as carvedilol and nebivolol, provide a broad spectrum of metabolic effects, including anti-inflammatory and antioxidant properties and a favorable impact on glucose and lipid metabolism.

Background: Parkinson's disease (PD) is a neurodegenerative disorder affecting both sexes, but differences exist between male and female in clinical manifestations, functional impact of symptoms and hormonal influences. Therefore, representativeness of females in PD trials indirectly determines the external validity of the clinical research in this field.
Objective: To estimate the representativeness of female in infusion therapy trials for advanced PD.

Sniffing is a motivated behavior displayed by nearly all terrestrial vertebrates. While sniffing is associated with acquiring and processing odors, sniffing is also intertwined with affective and motivated states. The systems which influence the display of sniffing are unclear.

Takotsubo cardiomyopathy (TTC), also known as stress-induced cardiomyopathy, is a rare condition in children that causes acute, severe, but often reversible systolic dysfunction of the left ventricle. Physical trauma is a recognized trigger, although distinguishing TTC from myocardial contusion in pediatric trauma cases can be challenging due to overlapping clinical features. We present the case of a six-year-old boy involved in a high-impact motor vehicle collision.
