Researchers in the UK say they can detect a common cause of high blood pressure thanks to a pioneering 10-minute scan.
Scientists claim the CT scan can light up hormone producing nodules which can cause hypertension, also known as high blood pressure, a condition that requires life-long treatment and the cause of which is often unknown.
The nodules, or growths, glow shortly after an injection is given and highlight an obvious cause for the condition, the scientists say.
According to the study, one in 20 people with high blood pressure have such growths in their hormonal glands.
Researchers say their findings solve a 60-year problem of how to detect the hormone-producing growth without a difficult procedure that is available in only a handful of hospitals, and often fails.
A total of 128 people participated in the study of a new scan after doctors found that their condition was caused by a steroid hormone called aldosterone.
Aldosterone causes salt to be retained in the body, driving up blood pressure.
Patients with excessive aldosterone levels in the blood are resistant to treatment with commonly used drugs for hypertension, and at increased risk of heart attack and stroke.
The research also found that, when combined with a urine test, the scan detects a group of patients who come off their blood pressure medicine after treatment.
The scan found that in two thirds of patients with elevated aldosterone secretion, it is caused by a benign nodule in one of the adrenal glands, which can then be safely removed.
Until now, the catheter test was unable to predict which patients would be cured of hypertension by surgical removal of the gland.
By contrast, the combination of a ‘hot nodule’ on the scan and urine steroid test detected 18 of the 24 patients who achieved normal blood pressure off all their drugs.
The research, published in Nature Medicine, was conducted on patients at St Barts, Guy’s and St Thomas’s hospitals in London, Cambridge University Hospital and the universities of Glasgow and Birmingham.
It was funded by the National Institute for Health and Care Research and Medical Research Council partnership, Barts Charity and the British Heart Foundation.
Morris Brown, co-senior author of the study and professor of endocrine hypertension at Queen Mary University in London, said: “These aldosterone-producing nodules are very small and easily overlooked on a regular CT scan.
“When they glow for a few minutes after our injection, they are revealed as the obvious cause of hypertension, which can often then be cured.
“Until now, 99 per cent are never diagnosed because of the difficulty and unavailability of tests. Hopefully this is about to change.”
Previous research by the group at Queen Mary University discovered that in 5 to 10 per cent of people with hypertension, the cause was a gene mutation in the adrenal glands, which resulted in excessive amounts of aldosterone being produced.

HOW DO SIM CARD SCAMS WORK?
Sim swap frauds are a form of identity theft.
They involve criminals conning mobile phone operators into issuing them with replacement Sim cards, often by claiming their phone has been lost or stolen
They use the victim's personal details - obtained through criminal methods - to convince such companies of their identity.
The criminal can then access any online service that requires security codes to be sent to a user's mobile phone, such as banking services.

New UK refugee system
- A new “core protection” for refugees moving from permanent to a more basic, temporary protection
- Shortened leave to remain - refugees will receive 30 months instead of five years
- A longer path to settlement with no indefinite settled status until a refugee has spent 20 years in Britain
- To encourage refugees to integrate the government will encourage them to out of the core protection route wherever possible.
- Under core protection there will be no automatic right to family reunion
- Refugees will have a reduced right to public funds
How to avoid crypto fraud
- Use unique usernames and passwords while enabling multi-factor authentication.
- Use an offline private key, a physical device that requires manual activation, whenever you access your wallet.
- Avoid suspicious social media ads promoting fraudulent schemes.
- Only invest in crypto projects that you fully understand.
- Critically assess whether a project’s promises or returns seem too good to be true.
- Only use reputable platforms that have a track record of strong regulatory compliance.
- Store funds in hardware wallets as opposed to online exchanges.
What is dialysis?
Dialysis is a way of cleaning your blood when your kidneys fail and can no longer do the job.
It gets rid of your body's wastes, extra salt and water, and helps to control your blood pressure. The main cause of kidney failure is diabetes and hypertension.
There are two kinds of dialysis — haemodialysis and peritoneal.
In haemodialysis, blood is pumped out of your body to an artificial kidney machine that filter your blood and returns it to your body by tubes.
In peritoneal dialysis, the inside lining of your own belly acts as a natural filter. Wastes are taken out by means of a cleansing fluid which is washed in and out of your belly in cycles.
It isn’t an option for everyone but if eligible, can be done at home by the patient or caregiver. This, as opposed to home haemodialysis, is covered by insurance in the UAE.

The Africa Institute 101
Housed on the same site as the original Africa Hall, which first hosted an Arab-African Symposium in 1976, the newly renovated building will be home to a think tank and postgraduate studies hub (it will offer master’s and PhD programmes). The centre will focus on both the historical and contemporary links between Africa and the Gulf, and will serve as a meeting place for conferences, symposia, lectures, film screenings, plays, musical performances and more. In fact, today it is hosting a symposium – 5-plus-1: Rethinking Abstraction that will look at the six decades of Frank Bowling’s career, as well as those of his contemporaries that invested social, cultural and personal meaning into abstraction.
