Analysis of the reasons for requesting HIV serology in the emergency department other than those defined in the targeted screening strategy of the "Urgències VIHgila" program and its potential inclusion in a future consensus document.

Objective: To describe other reasons for requesting HIV serology in emergency departments (ED) other than the 6 defined in the SEMES-GESIDA consensus document (DC-SEMES-GESIDA) and to analyze whether it would be efficient to include any of them in the future.

Methods: Review of all HIV serologies performed during 2 years in 20 Catalan EDs. Serologies requested for reasons not defined by the DC-SEMES-GESIDA were grouped by common conditions, the prevalence (IC95%) of seropositivity for each condition was calculated, and those whose 95% confidence lower limit was >0.

GOIZ ZAINDU study: a FINGER-like multidomain lifestyle intervention feasibility randomized trial to prevent dementia in Southern Europe.

Background: GOIZ ZAINDU ("caring early" in Basque) is a pilot study to adapt the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) methodology to the Basque population and evaluate the feasibility and adherence to a FINGER-like multidomain intervention program. Additional aims included the assessment of efficacy on cognition and data collection to design a large efficacy trial.

Method: GOIZ ZAINDU is a 1-year, randomized, controlled trial of a multidomain intervention in persons aged 60+ years, with Cardiovascular Risk Factors, Aging and Dementia (CAIDE) risk score ≥ 6, no diagnosis of dementia, and below-than-expected performance in at least one of three cognitive screening tests.

Systemic toxicity of snake venom metalloproteinases: Multi-omics analyses of kidney and blood plasma disturbances in a mouse model.

Snakebite envenomation is classified as a Neglected Tropical Disease. Bothrops jararaca venom induces kidney injury and coagulopathy. HF3, a hemorrhagic metalloproteinase of B.

Hereditary hemochromatosis: An update vision of the laboratory diagnosis.

Haemochromatosis (HC) is an inherited disorder of iron metabolism. The 85-90% of Hereditary hemochromatosis cases are caused by mutations in HFE gene (HC type 1). The remaining 10-15% of HC cases are caused by mutations in other non-HFE genes (HJV, HAMP, TRF2, SLC40A1, BMP6).

A Single Dose of Psilocybin Increases Synaptic Density and Decreases 5-HT Receptor Density in the Pig Brain.

A single dose of psilocybin, a psychedelic and serotonin 2A receptor (5-HTR) agonist, may be associated with antidepressant effects. The mechanism behind its antidepressive action is unknown but could be linked to increased synaptogenesis and down-regulation of cerebral 5-HTR. Here, we investigate if a single psychedelic dose of psilocybin changes synaptic vesicle protein 2A (SV2A) and 5-HTR density in the pig brain.
