Early elevations in arterial pressure: a contributor to rapid depressive symptom emergence in female Zucker rats with metabolic disease?

One of the growing challenges to public health and clinical outcomes is the emergence of cognitive impairments, particularly depressive symptom severity, because of chronic elevations in metabolic disease and cerebrovascular disease risk. To more clearly delineate these relationships and to assess the potential for sexual dimorphism, we used lean (LZR) and obese Zucker rats (OZR) of increasing age to determine relationships between internal carotid artery (ICA) hemodynamics, cerebral vasculopathies, and the emergence of depressive symptoms. Male OZR exhibited progressive elevations in perfusion pressure within the ICA, which were paralleled by endothelial dysfunction, increased cerebral arterial myogenic activation, and reduced cerebral cortex microvessel density.

Cognitive, affective, and behavioral engagement with science news predicted by the use of accessibility strategies in science-minded and general audiences.

Numerous studies have explored internal factors such as cultural values and acquired knowledge accounting for how people engage with science. However, it remains unclear how external factors embedded in science texts relate to audience engagement. A content analysis of 298 text-based popular science news articles and their following 5852 reader comments was conducted in two Israeli audiences, science-minded and general readers, to explore how the accessibility strategies embedded in these articles relate to cognitive, affective, and behavioral engagement.

Custo-utilidade de terapias-alvo comparadas à dacarbazina para o tratamento de primeira linha do melanoma avançado não-cirúrgico e metastático no Sistema Único de Saúde do Brazil.

Objective: To estimate the incremental cost-utility ratio (ICUR) of isolated and combined targeted therapy regimens compared to dacarbazine for first-line treatment of advanced and metastatic melanoma with BRAF V600 mutation.

Methods: A Markov model with three health states (no progression, progression and death), monthly duration cycle and 10-year time horizon was constructed to compare targeted therapy regimens (vemurafenib, dabrafenib, vemurafenib/cobimetinib and dabrafenib/trametinib) with dacarbazine chemotherapy under the Brazilian public health perspective. One-way and probabilistic sensitivity analyses were performed.

Aquaporin 11 variant associates with kidney disease in type 2 diabetic patients.

Kidney disease, a common complication of diabetes, associates with poor prognosis. Our previous animal model studies linked aquaporin (AQP)11 to acute kidney injury, hyperglycemia-induced renal impairment, and kidney disease in diabetes. Here, we report the AQP11 rs2276415 variant as a genetic factor placing type 2 diabetic patients at greater risk for the development of kidney disease.
