Today's episode is the second and final of our obstetric cardiac disease series where we take a close look at a few case scenarios with special guest, Dr Michael Toon. Our third case takes a closer look at pulmonary hypertension in pregnancy and how this impacts the delivery and our anaesthetic options. We then end with a case in which a patient with congenital cardiac disease and a fontan circulation requires semi-urgent delivery.

S6 Ep. 7: Let it be

Today, we're tackling the absolutely mammoth topic of hyponatremia after JAMA recently published a fantastic article about its diagnosis and management. Part 2's episode focuses on determining the cause of a patient's hypotonic hyponatremia. From here we also go on to discuss the pathophysiology of both the Syndrome of Inappropriate ADH secretion (or SIADH) and cerebral salt wasting before discussing the markedly different managements for these two conditions.Lastly, we talk through the principles of managing hyponatremia.

S6 Ep. 6: Saltwater, part 2

Today, we're tackling the absolutely mammoth topic of hyponatremia after JAMA recently published a fantastic article about its diagnosis and management. We start with a review of some relevant physiology before talking about the ways in which hyponatremia can present, and the approach to determining the underlying cause of the hyponatremia.In this episode, we specifically talk about determining whether the patient has either hypertonic, isotonic or hypotonic hyponatremia, as well as a discussion of the causes of hypertonic and isotonic hyponatremia. From here, we go on to focus on the relevant history and examination when working up a patient with hypotonic hyponatremia in order to further sub classify their hypotonic hyponatremia as being hypovolaemic, euvolaemic or hypervolaemic.

Today, we share our third discussion in our four part series about statistics with Dr Shannon Morrison. In this episode, we discuss the following topics:sensitivity and specificitypositive predictive values (PPV) and negative predictive values (NPV)risk ratiosodds ratiosnumber needed to treat (NNT) and number needed to harm (NNH)And here are the calculations for Shannon's working example of sensitivity, specificity,  PPV and NPV (looking at diagnostic tests for the covid-19 pandemic):Part 1 - PCR tests for Covid-19 (2020):Let’s say that the prevalence of COVID was 1 in 100,000 people.  PCR testing has (roughly) sensitivity of 90% and specificity of 99%.That means, if you took 1,000,000 people and did a PCR test for COVID:10 people actually had COVID9 of those 10 people would test positive (sensitivity 90%) - and that means 1 of those 10 people would test negative999,990 people did not have COVID989,990 of those people would correctly test negative (sensitivity 99%)So that means 10,000 people would incorrectly test positiveFrom those numbers:10,009 people tested positive9/10,009 correctly tested positive - so the PPV is 0.09%And:989991 people tested negative989990/989991 correctly tested negative - so the NPV is 99.99%Part 2 - PCR tests for Covid-19 (2022): Now let’s say that 1 in 100 people have COVID.  Let’s say we do a PCR test on one million people again.Now:10,000 people have COVID, and 9,000 of them test positive (so 1,000 of them test negative)990,000 people do not have COVID - 980,100 of them test negative (and 9,900 test positive)PPV = 9000/(9000+9900) = 47.6%NPV = 99.89%The test hasn’t changed - but now if you get a positive result, there is a 47.6% chance of it being true.  So for the same test: as the prevalence increases, the PPV increases (0.09% ⇒ 47.6%) and the NPV decreases (99.99% → 99.89%).Part 3 - RAT tests for Covid-19:Let’s just accept an overall sensitivity of 60% and specificity of 99%.  We’re going to test a million people again.10,000 people have COVID6000 will correctly test positive (sensitivity 60%)That means 4000 incorrectly test negative990,000 people do not have COVID980,100 of them will correctly test negative (99% specificity)9,900 will incorrectly test positiveAs the sensitivity decreases, the number of false positives don’t change, but the number of false negatives increases - in this case, from 1000 to 4000.And (you can take my word for this one!) - as the specificity decreases, the number of false negatives doesn’t change but the number of false positives increases.Resources for today's episode: Zedstatistics (youtube channel) - short videos explaining various concepts in statistics from an Australian Statistician Johns Hopkins Coursera Short Course - Biostatistics in Public Health (this course has free enrolment and takes approx 4 months to complete - it commenced on January 30th) Feel free to email us at deepbreathspod@gmail.com if you have any questions, comments or suggestions.
