What are the pharmacodynamics of loop diuretics? A recent editorial was entitled ‘Loop diuretics in heart failure: few facts and lots of prejudice’.1 I would argue that we have forgotten or distorted some

Fascinating paper suggesting the assumption that there is a sigmoid dose response relationship and threshold effect ( "all-or-nothing") for loop diuretics rests on repeated misinterpretation of original studies from the 70s and 80s. #nephsky #cardiosky #emimcc academic.oup.com/ehjcvp/artic...

Portrait of Edward Jenner leaning against a tree

Happy 276th birthday Edward Jenner! What a time for vaccination: 154 million lives saved in the last 50 years, tempered with an increase in vaccine preventable diseases across the world, vaccine sceptics in charge in the US, and cuts to overseas aid threatening global immunisation programmes.

Contemporary Hormonal Contraception and Risk of Venous Thromboembolism This study assesses the risk of venous thromboembolism of different forms of hormonal contraception, including pills with estrogen and progestin, vaginal rings, patches, progestin-only pills, intrauterine devices, implants, and injections.

The risk of venous thromboembolism (VTE) varies across contemporary hormonal contraceptives, with the highest risk associated with combined pills.

Paper in this week's NEJM shows that in patients with atrial fibrillation and stable coronary artery disease, edoxaban monotherapy is superior to the combination of edoxaban plus an antiplatelet drug. Major difference was in bleeding rather than reduction in ischaemic events.

Yes I've had that thought before too. If no pre-ICS FBC, but eosinophils normal on ICS/LABA, pt stable and no other Hx of inflam resp disease then probably reasonable to try switch. Can always recheck FBC again at later date to check eosinophil trend 👍.

Not a resp expert...

But my understanding is if eosinophils normal + no PMH asthma, then ideally to remove ICS as can inc risk of pneumonia in COPD pts. So yes - switch to LABA/LAMA.

Totally agree - hard to get patients on board when they feel strongly about their existing txt!

Interesting conclusion from Cochrane. Are we currently over treating BP in this cohort?

Useful paper. Fesoterodine's DT price hugely reduced in recent months, so no excuse to prescribe oxybutynin any more based on cost. Fesoterodine now included as 1st line on Somerset Prescribing Formulary

I understood that BlueSky was supposed to be a 'safer' space than X... On browsing feeds on Christianity/religion, perhaps this is not a safe space after all!

Is there space for people of faith to encourage each other here, or should we move elsewhere?!

Year 2 medics are still early on in programme of study... Maybe keep simple? Prescribing - perhaps consider various factors that affect prescription choice (ease of use, availability, cost effectiveness, clinician "favourites"). Deprescribing - lots of good resources such as STOPP/START
