Intermittent documentation of blood pressure values does not provide comprehensive evaluation of the hemodynamic response during continuous intravenous medication administration.

Blood pressure (BP) is a dynamic measure that is frequently discussed in static terms. There exist many limitations in current documentation systems whereby documented BP values may not be reflective of the dynamic variability of BP. This study used an observational, prospective, non-randomized study design to examine the variability in BP response during intravenous vasoactive medication administration in an intensive care unit setting.

Interlaboratory Measurement of Adeno-Associated Virus: Comparative Quantification of Full and Empty Capsids.

Recombinant adeno-associated virus (AAV) is one of the main viral vector-based gene therapy platforms. AAV is a virus consisting of a ≈25 nm diameter capsid with a ≈4.7 kb cargo capacity.

Extra-adrenal adrenocortical cancer associated with multiple endocrine neoplasia type 1.

Summary: Adrenocortical carcinoma (ACC) is a rare malignant tumour arising from the adrenal cortex, with an estimated annual incidence of one to two patients per million. Ectopic ACCs are extremely rare. The majority of ACCs are sporadic; however, ACC has been linked with genetic disease processes, including multiple endocrine neoplasia type-1 (MEN-1).

Dorsal root ganglion toxicity after AAV intra-CSF delivery of a RNAi expression construct into non-human primates and mice.

Dorsal root ganglion (DRG) toxicity has been consistently reported as a potential safety concern after delivery of adeno-associated viruses (AAVs) containing gene-replacement vectors but has yet to be reported for RNAi-based vectors. Here, we report DRG toxicity after AAV intra-CSF delivery of an RNAi expression construct-artificial microRNA targeting superoxide dismutase 1 (SOD1)-in non-human primates (NHPs) and provide evidence that this can be recapitulated within mice. Histopathology evaluation showed that NHPs and mice develop DRG toxicity after AAV delivery, including DRG neuron degeneration and necrosis and nerve-fiber degeneration that were associated with increases in cerebrospinal fluid (CSF) and serum phosphorylated neurofilament heavy chain (pNF-H).

Does intracranial pressure vary based on external ventricular drainage? A real-world clinical observation study.

Background: External ventricular drains (EVDs) are placed in patients with increased intracranial pressure (ICP) to serve as a cerebrospinal fluid (CSF) pressure flow diverter and ICP monitor. EVD management practice among institutions and practitioners varies greatly, with little evidence supporting ideal ICP recording and CSF drainage practice.

Objective: This study's aim is to determine variations in ICP across 21 min before and after CSF drainage.
