Background: Reperfusion treatment (RT) is administered to individuals with posterior circulation strokes (PCS) later and less frequently. We aimed to study the impact of demographic and clinical factors on the decision for RT in PCS.
Methods: We conducted a retrospective analysis of the data from 500 subjects admitted to the tertiary stroke centre's emergency department between 2018 and 2020 due to PCS. Demographic and clinical factors were analysed among three groups: the RT group, the group with no RT because of absolute contraindications (ACI), and the group with no RT because of relative contraindications (RCI).
Results: Of the patients, 202 (40.3%) were female. The median NIHSS was four (4), and the subjects' median age was 69 (18). RT was performed on 120 (24%) subjects. FAST symptoms (OR-5.62, 95% CI [2.90-12.28]) and higher NIHSS (OR-1.13, 95% CI [1.09-1.18]) at presentation, atrial fibrillation (OR-1.56, 95% CI [1.02-2.38]), hypertension (OR-2.19, 95% CI [1.17-4.53]) and diabetes (OR-1.70, 95% CI [1.06-2.71]) increased the chance of RT. Late arrival was the most prevalent ACI for 291 (58.2%) patients. FAST-negative subjects (OR-2.92, 95% CI [1.84-4.77]) and males (OR-1.58, 95% CI [1.11-2.28]) had a higher risk of arriving late. Because of RCI, 50 (10%) subjects did not receive RT; the majority were above 80 and had NIHSS ≤ 5. Subjects with RCI who received the RT had a higher NIHSS (4 vs. 3, < 0.001), higher hypertension (59 (92.2%) vs. 35 (77.8%), = 0.032) and heart failure (23 (35.9%) vs. 7 (15.6%), = 0.018) prevalence. There was a trend for less RT in females with RCI.
Conclusions: Late arrival was the most common barrier to RT, and the male gender increased this risk. because of relative contraindications, 10% of subjects were not considered for RT. The presence of FAST symptoms, vascular risk factors, and a higher NIHSS increased the chance of RT.

Background: Preclinical testing in animal models is a critical component of the drug discovery process. Over the past three decades hundreds of interventions have demonstrated preclinical efficacy for ameliorating cognitive impairments in animal models; however, none have translated to efficacy in Alzheimer's disease (AD) clinical trials. This lack of translation suggests that there are issues with the animal models employed, the preclinical assays, and poor scientific rigor and reproducibility during execution.

Succession is one of the most extensively studied ecological phenomena, yet debates persist about the importance of dispersal and external factors in driving this process. We aimed to quantify the influence of these factors by investigating how wing-related traits evolve across succession of blowfly (Diptera: Calliphoridae) communities in South Brazil. Rat carrion was placed in both forest and grassland habitats, and the associated blowfly communities were documented throughout the decomposition process.

Studies in humans and rodents show exercise in pregnancy can modulate maternal blood pressure, vascular volume, and placental efficiency, but whether exercise affects early uteroplacental vascular adaptations is unknown. To investigate this, CBA/J female mice mated with BALB/c males to generate healthy uncomplicated pregnancies (BALB/c-mated) or mated with DBA/2J males to generate abortion-prone pregnancies (DBA/2J-mated), were subjected to treadmill exercise (5 days/week, 10 m/min, 30 min/day for 6 weeks before and throughout pregnancy), or remained sedentary. In uncomplicated pregnancies, exercise caused symmetric fetal growth restriction in fetuses evidenced by reductions in fetal weight, crown-to-rump length, abdominal girth and biparietal diameter.
