New guideline focused on managing hypertension in primary care

2025-05-26
(Press-News.org) A new guideline to diagnose and treat hypertension is aimed at helping primary care clinicians, including family physicians, nurses, nurse practitioners, and pharmacists, manage the disease. The new guideline, the first of 2 from Hypertension Canada, is published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.241770, and will be republished with permission in Canadian Family Physician and Canadian Pharmacists Journal, with a summary in Canadian Nurse.

Hypertension is the most common modifiable risk factor for heart disease and death, affecting about 1 in 4 adults in Canada. Canada has been a leader in hypertension treatment and control, but this success has been on the downward trend in recent years. Discrepancies in optimal blood pressure targets, complex guideline recommendations, less engagement with front-line health care providers and other factors may be fuelling this decline.  

“As primary care is where most hypertension is managed, supporting primary care practitioners to better diagnose and manage this disease will improve hypertension care at the population level and benefit people in Canada,” says Dr. Ross Tsuyuki, past president, Hypertension Canada. “We hope these practical recommendations will help with implementing hypertension care in everyday clinical practice.”

Developed by Hypertension Canada, the guideline uses the World Health Organization’s (WHO) HEARTS framework to improve cardiovascular health around the globe with an adaptable approach that can be tailored to countries’ unique needs. In the part of the United States where it was developed, it improved local hypertension control rates from 44% to 90% in just over a decade. 

The guideline, based on the latest evidence, provides recommendations most relevant to primary care on assessing blood pressure (BP) and definitions of hypertension for diagnosis, healthy lifestyle changes, and pharmacotherapy for treatment, including hard-to-treat hypertension. In selecting medications to treat hypertension, the guideline committee considered efficacy, tolerability, cost, coverage, availability, protection from future drug shortages, and ability to split pills.

One important change is a lower threshold for BP targets.

“The lower BP thresholds adopted for both defining hypertension and treatment targets relative to previous Hypertension Canada guidelines means that more people will be labelled as having hypertension, which may have meaningful personal implications, like stigma, insurance coverage, and more,” says guideline co-chair Dr. Greg Hundemer. “However, the committee thought that the current evidence strongly supports the lower thresholds to promote early detection of, and intervention for, hypertension, which will help mitigate long-term cardiovascular complications at the population level.”

A committee of family physicians, pharmacists, a nurse practitioner, hypertension specialists, and a methodologist developed the guideline. In addition, 4 patient partners with lived experience of hypertension provided feedback during guideline development and helped create a patient support tool.

The guideline is the first of 2, with the second intended to be a comprehensive guideline to address more complex aspects of hypertension management.

“This guideline is not intended to be applied in all clinical scenarios, such as managing hypertension in children or in people who are pregnant or trying to become pregnant. Separate guidelines are available for these patient populations. Rather, it is a complement to an upcoming comprehensive guideline aimed to help with more complex and nuanced aspects of hypertension management, such as resistant hypertension, but should cover about 95% of most uncomplicated hypertension cases in the community,” says Dr. Rémi Goupil, guideline co-chair.

New blood test enables the rapid diagnosis of thousands of rare genetic diseases

2025-05-25
Milan, Italy: A new, rapid testing method will greatly help the diagnosis of rare diseases in babies and children, according to research to be presented to the annual conference of the European Society of Human Genetics today (Monday). While rare genetic diseases are uncommon, as their name suggests, there are more than 7,000 types of disease caused by mutations in more than 5,000 known genes, affecting approximately 300 million individuals worldwide. Currently about half of all patients with a suspected rare disease remain undiagnosed and existing testing methods for undiagnosed conditions are typically slow, ...

Genetic investigations reveal reason for severe neuropathy after infection

2025-05-25
Milan, Italy: Neuropathy, a disorder in which damage to nerves can impair sensation and movement, has many causes, including infection1. Now, researchers from the UK have identified distinct genetic changes in a newly-discovered neuropathy and believe that their work will provide insights into the causal mechanism and why some previously healthy people develop neuropathies after infection whereas others do not. Dr Rob Harkness, a postdoctoral research Fellow at the University of Manchester, Manchester, UK, will tell the annual ...

Urban rewilding as a key strategy to combat biodiversity decline

2025-05-25
In recent years, the concept of "rewilding" has risen to prominence in the conservation community, but to date, most efforts have been concentrated on large protected areas far from cities—and consequently, far from urban areas suffering pronounced biodiversity losses. In a recently published BioScience article, Patrick Finnerty (University of Sydney) and colleagues make the case for "urban rewilding" as a vital approach for addressing biodiversity losses, focusing on the rapidly expanding cities that are soon expected to be home to ...

A root development gene that’s older than root development

2025-05-25
A gene that regulates the development of roots in vascular plants is also involved in the organ development of liverworts — land plants so old they don’t even have proper roots. The Kobe University discovery highlights the fundamental evolutionary dynamic of co-opting, evolving a mechanism first and adopting it for a different purpose later. When scientists discover that a gene is necessary for the development of a trait, they are quick to ask since when this gene has been involved in this and how the evolution of the gene has ...

Research reveals missed opportunities to save George Floyd’s life

2025-05-25
The murder of George Floyd could have been avoided if police had responded to the concerns of bystanders reveals research led by Lancaster University. George Floyd was murdered by Minneapolis police officer Derek Chauvin on May 25 2020. For the first time, psychologists have analysed 12 videos recorded on the body-worn cameras of the attending officers, the smartphones of bystanders and local CCTV cameras from 19:55 until 20:42 (CST) on the date of his death. Their research published in American Psychologist examines the range of verbal and physical ...

HKUST discovers novel elastic alloy achieving 20x temperature change and 90% carnot efficiency in solid-state heat pumping

Researchers at the School of Engineering of the Hong Kong University of Science and Technology (HKUST) have developed a novel elastic alloy called Ti₇₈Nb₂₂, which achieves remarkable efficiency for solid-state heat pumping and exhibits a reversible temperature change (ΔT) ability that is 20 times greater than that of conventional metals when stretched or compressed, offering a promising green alternative to traditional vapor-compression heating and cooling technologies. Nearly half of the world’s energy is consumed for heating, including district heating in the building sector and process heating in various industrial sectors. Currently, global heat ...

Early prediction of preterm birth in cell-free RNA may revolutionize prevention strategies

2025-05-24
Children born before 37 weeks of gestation have a considerably increased risk of dying before they reach the age of five. Predicting the risk of preterm birth (PTB) and hence implementing preventive strategies is complicated by the heterogeneity of the condition, the many unknown mechanisms involved, and the lack of reliable predictive tools. Now, however, researchers have been able to show that blood cell-free RNA (cfRNA) signatures can predict PTB over four months before delivery date, the annual conference of the European Society of Human Genetics will hear ...

European regulation needed to prevent the birth of children with inherited cancer-causing genetic mutation after sperm donation

2025-05-23
A case in which a sperm donor was later found to be carrying a cancer-causing pathogenic variant in his gametes has highlighted the problems of regulating gamete donation at European and international level, the annual conference of the European Society of Human Genetics will hear today (Saturday). Dr Edwige Kasper, a specialist in genetic predisposition to cancer at the Rouen University Hospital, Rouen, France, will say that the lack of cross-border regulation in Europe can result in the multiple use of gametes in  families and risks inbreeding and the  abnormal  dissemination of inherited diseases. Towards ...

Assembly instructions for enzymes

2025-05-23
In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) now derived universal rules to enable the de novo design of optimal enzymes. As an example, they considered the enzymatic reaction of breaking a dimer into two monomer molecules. Considering the geometry of such an enzyme-substrate-complex, they identified three golden rules that should be considered to build a functional enzyme. First, the interface of both enzyme and molecule should be located at their respective smaller end. This way, a strong coupling between both of them ...
