An operation that targets the nerves connected to the kidney has been found to significantly reduce blood pressure in patients with hypertension, according to the results of a clinical trial led in the UK by Queen Mary University of London and Barts Health NHS Trust, and supported by the National Institute for Health Research (NIHR).

The results are published in The Lancet and have been presented at the EuroPCR congress in Paris.

If the findings are confirmed in more extensive clinical trials, the surgery could offer hope to patients with high blood pressure who do not respond to drugs, and are at increased risk of cardiovascular diseases, including stroke and heart attack.

The international clinical trial, carried out from 2017 to 2018 at St Bartholomew's Hospital in the UK by the NIHR Barts Biomedical Research Centre, tested a one-hour operation called 'renal denervation', which uses ultrasound energy to disrupt the nerves between the kidneys and the brain that carry signals for controlling blood pressure.

146 patients in the United States, France, Germany, the Netherlands, Belgium and the United Kingdom were randomised to receive either renal denervation or a 'sham procedure' -- the surgical equivalent of a placebo. Patients also remained off blood pressure medications for two months unless specified blood pressure levels were exceeded.

After two months, the renal denervation group experienced an 8.5 mm Hg reduction in blood pressure, which was a 6.3 mm Hg greater reduction compared with the sham group. More than 66 per cent of subjects treated with renal denervation demonstrated a 5 mm Hg or greater reduction in blood pressure, compared with 33 per cent in the sham group.

[...] The study has limitations including the short follow-up time of two months. This was done for safety reasons to minimise the duration of patients being off antihypertensive medications. Longer follow-up of this trial and additional numbers of treated patients will be necessary to provide greater assurance of safety and to exclude rare adverse events.

    I never understand how posting to the wrong thread can happen. What method are you using to view and post on this site?

    From personal experience: You open two tabs with two different stories, write you comment in a text editor / google some facts before making even more a fool out of yourself / google what's the difference between then/than for the millions time (and still get it wrong until you stop trying), switch back to the browser, hit reply, paste and hit submit.

      btw, this was an example of me not doing it:

      write you comment -> write your comment

      millions -> millionth

      Average wise I think I get two to four errors per paragraph that need primary proofing that a spell checker can't catch and I just can't stomach. For heavy weight writing I'll modify my style to something more minimal and academic, review the moods (indicative, subjunctive, imperative), google synonyms and adjust punctuation. Very rarely I might even play with the pacing and meter if the mood (read: blood alcohol content) strikes.

        I like to keep it simple. I write words that are VERY EASY to spell. Like "tweet" instead of "comfefe

          I want to laugh but I can't help sympathize imagining what he went through:
          1. Despite the negative press covfe...
          2. Two thoughts surface at once: I was writing "cover" but it turned out "covfe"; I should have written "press coverage".
          3. fe.
          4. Agha for fuck sake! Wait what was I writing about?
          5. "Mr. President, your coffee is ready.".
          6. As the spelling of coffee rises in his subconscious, a 3-way brain fart is triggered.
          7. With one hand reaching for the cup, the other hits Post instead of Cancel but Trump fails to notice.

            I’ve never taken drugs of any kind, never had a glass of alcohol. Never had a cigarette, never had a cup of coffee. Although I sold a line of coffee pods, the most delicious and luxurious coffees in the world. I called them Trump Select. But unfortunately they were ahead of their time -- folks just weren't ready for the coffee pod concept.

    WTF? Obviously I was commenting on "Trump Violates First Amendment by Blocking Twitter Users From Feed, Judge Says".
    How I wound up on this thread I'll never know.
