The localisation of quantitative trait loci (QTL) is the first step towards gene identification. This is then verified by the construction of reciprocal congenic strains. The hypertensive SHRSP and normotensive WKY strains were used in a speed congenic approach to confirm the existence of a QTL on rat chromosome 2. Systolic baseline and salt loaded blood pressures were measured by radiotelemetry. Transfer of the chromosome 2 blood pressure QTL region from WKY into an SHRSP background significantly reduced blood pressure, with the increased significance at the salt loaded period, compared to the SHRSP. The reciprocal congenic blood pressure showed a significantly increased baseline systolic pressure compared to the WKY, with no change in significance at the salt loaded period. Thus we have successfully captured a gene(s) which contribute to blood pressure regulation in both congenic strains. This will facilitate further positional cloning of the causative genes first in this model and then in human essential hypertension.

Implementing Self-Measured Blood Pressure in Primary Care: A Feasible and Systematic Approach.
Am J Med Qual
January 2025
Improving Health Outcomes, American Medical Association, Chicago, IL.
Randomized clinical trials and clinical practice guidelines recommend the use of self-measured blood pressure (SMBP) to help improve the treatment of patients with hypertension. Many clinicians use SMBP in their practices, but there is significant variability in how SMBP is implemented in their day-to-day practice. This quality improvement study details the pragmatic and real-world approach clinicians and administrators used at 3 sites of the IHA Medical Group, a part of Trinity Healthcare, to implement the American Medical Association (AMA) 7-Step SMBP framework as part of the larger AMA hypertension quality improvement program AMA MAP BP.

Background: There is limited and conflicting evidence on the comparative cardiometabolic safety and effectiveness of aripiprazole in the management of severe mental illness. We investigated the hypothesis that aripiprazole has a favourable cardiometabolic profile, but similar effectiveness when compared to olanzapine, quetiapine, and risperidone.
Methods And Findings: We conducted an observational emulation of a head-to-head trial of aripiprazole versus olanzapine, quetiapine, and risperidone in UK primary care using data from the Clinical Practice Research Datalink.

Managing uncontrolled and noncompressible bleeding presents a major challenge in emergency trauma care. Methods to halt bleeding quickly and efficiently, without applying direct pressure on the wound, have become a key focus of research. Herein, a novel fructose-modified chitosan/gelatin composite sponge has been developed, exhibiting high elasticity, low rebound pressure, and excellent cell compatibility.

Background: Cardiovascular disease (CVD) is a major global health issue, with approximately 70% of cases linked to modifiable risk factors. Digital health solutions offer potential for CVD prevention; yet, their effectiveness in covering the full range of prevention strategies is uncertain.
Objective: This study aimed to synthesize current literature on digital solutions for CVD prevention, identify the key components of effective digital interventions, and highlight critical research gaps to inform the development of sustainable strategies for CVD prevention.
