(Press-News.org) A comprehensive new analysis by researchers at Queen Mary University of London warns that England has lost the substantial gains made in high blood pressure prevention, diagnosis and management during the 2000s.
Drawing on data from more than 67,000 adults who participated in the annual Health Survey for England between 2003 and 2021, researchers report that the rates of high blood pressure, undiagnosed hypertension and inadequate treatment control have plateaued since 2011 and deteriorated sharply in the aftermath of the Covid-19 pandemic.
Findings of the study published in BMJ Medicine show that while high blood pressure prevalence fell steadily from 37.8 per cent in 2003 to 33.2 per cent in 2018, this improvement stalled thereafter, with little evidence of continued progress up to 2021. Rates of undiagnosed hypertension declined markedly from 32.6 per cent in 2003 to 23.7 per cent in 2011. Subsequently rose back to 32.4 per cent by 2021, effectively returning to levels last observed two decades ago.
The study also revealed that the proportion of people with undiagnosed high blood pressure who successfully achieved blood pressure control increased strongly until 2011 but showed no meaningful improvement over the following decade, dropping from 63.1 per cent in 2011 to 56.8 per cent in 2021. This indicates that an estimated five million adults in England may now be living with undiagnosed high blood pressure, and roughly another five million have diagnosed but uncontrolled high blood pressure.
Dr Ajay Gupta, senior author and Consultant in Cardiovascular Medicine and Clinical Pharmacology at Queen Mary said, “Despite early gains, only 38.3% of people with hypertension now have adequately controlled blood pressure—far below the envisioned 80% target if trends in the improvement continued in 2010’s. This shortfall may be a key driver of recently seen rise in the cardiovascular deaths. Urgent action is needed from policymakers and healthcare providers.”
High blood pressure remains the leading cause of cardiovascular deaths in England. The authors note that premature cardiovascular mortality in England has risen in recent years and closely tracks the increasing burden of poorly controlled and undiagnosed high blood pressure. The stagnation in blood pressure control, combined with growing levels of obesity, higher average salt intake, widening socioeconomic inequalities and increasing prevalence if mental health disorders, suggests that broader changes in health policy, lifestyle and social conditions have contributed to the erosion of earlier progress.
The study also evaluated the impact of the Covid-19 pandemic. It identified a pronounced deterioration of high blood pressure detection and management between 2019 and 2021, characterised by declining blood pressure control and reduced medication use. They attribute these changes partly to pandemic-related disruptions, including reduced access to routine primary care and curtailed opportunities for blood pressure measurement.
The authors emphasise that reversing these declines will require coordinated action, including a strengthened national salt-reduction programme, improved access to diagnostic services, robust strategies to remove barriers to medication adherence and a renewed emphasis on clinical education designed to reduce therapeutic inertia.

DNA transcription is a tightly choreographed event. A new study reveals how it is choreographed
2025-11-27
Life’s instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must advance down the gene in perfect sync with other biological processes; aberrations in the movement of this enzyme have been linked to cancer and aging. But technical hurdles prevented them from precisely determining how this important molecular machine moves along DNA, and what governs its pauses and accelerations.

Drones: An ally in the sky to help save elephants!
2025-11-27
Key Findings
Drones can be a valuable, non-invasive tool for observing elephant families and aiding long-term conservation efforts.
Elephants can habituate to drones - showing fewer signs of disturbance both during a single flight and after repeated exposures. Disturbance behaviours were 70% less likely on successive drone flights.
Careful flight protocols matter - when flown high (120 m or above), with a downwind approach, and steadily, drones cause minimal stress.
Just under half of all trials showed no signs of disturbance, and those that did quickly returned to levels comparable with pre-exposure.

RNA in action: filming ribozyme self-assembly
Researchers have visualised, in unprecedented detail, how a large RNA molecule assembles itself into a functional machine
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study published in Nature Communications by Marcia group, has captured, for the first time, a ribozyme in ...
Non-invasive technology can shape the brain’s reward-seeking mechanisms
2025-11-27
The nucleus accumbens is a tiny element of the human brain triggered when we experience something enjoyable, and used to help us learn behaviours that lead to rewards.
A new study has shown for the first time that its influence on human behaviour can be altered using transcranial ultrasound stimulation (TUS).
Applying the technique for just over a minute at a time, researchers were able to influence how people learned the links between certain cues and rewards.
The result was that they were more likely to repeat a choice that had previously paid off, their learning rates following positive outcomes increased and they were more likely to make ...
X-ray imaging captures the brain’s intricate connections
2025-11-27
An international team of researchers led by the Francis Crick Institute, working with the Paul Scherrer Institute, have developed a new imaging protocol to capture mouse brain cell connections in precise detail.
In work published today in Nature Methods, they combined the use of X-rays with radiation-resistant materials sourced from the aerospace industry.
The images acquired using this technique allowed the team to see how nerve cells connect in the mouse brain, without needing to thinly slice biological tissue samples.
Volume electron microscopy (volume EM) has been the gold standard for imaging how nerve cells connect as ‘circuitry’ ...
Plastic pollution is worsened by warming climate and must be stemmed, researchers warn
2025-11-27
A new review published in Frontiers in Science is calling for urgent action to avoid irreversible ecological damage by stemming the tide of microplastics entering the environment.
Climate change conditions turn plastics into more mobile, persistent, and hazardous pollutants. This is done by speeding up plastic breakdown into microplastics - microscopic fragments of plastic - spreading them considerable distances, and increasing exposure and impact within the environment.
This is set to worsen as both plastic manufacturing and climate effects increase. Global annual plastic ...
Europe’s hidden HIV crisis: Half of all people living with HIV in Europe are diagnosed late, threatening to undermine the fight against AIDS
2025-11-27
Europe is failing to test and treat HIV early, with over half (54%) of all diagnoses in 2024 being made too late for optimal treatment. New data released today by the European Centre for Disease Prevention and Control (ECDC) and the WHO Regional Office for Europe warns that this critical testing failure, combined with a growing number of undiagnosed cases, is severely jeopardising the 2030 goal of ending AIDS as a public health threat.
According to the annual HIV/AIDS surveillance report, 105 922 HIV diagnoses were made in the ...

Nobel Prize-awarded material that puncture and kill bacteria
2025-11-27
Bacteria that multiply on surfaces are a major headache in healthcare when they gain a foothold on, for example, implants or in catheters. Researchers at Chalmers University of Technology in Sweden have found a new weapon to fight these hotbeds of bacterial growth – one that does not rely on antibiotics or toxic metals. The key lies in a completely new application of this year's Nobel Prize-winning material: metal-organic frameworks. These materials can physically impale, puncture and kill bacteria before they have time to attach ...
Michigan cherry farmers find a surprising food safety ally: falcons
2025-11-27
The cherry harvest wrapped up months ago. But in northern Michigan, some growers are already anticipating the spring resurgence of a tiny raptor that could benefit next season’s crop.
The American kestrel is the smallest falcon in the U.S. As birds of prey, kestrels deter smaller birds that like to snack on farmers’ fruit. But new research suggests that these winged security guards may have an additional benefit: food safety.
That’s according to a study from Michigan State University, ...
