You know the best April Fool’s joke? It’s where you pull the prank on April 10 instead of April 1, because then no one’s expecting it.

Athletes lose extra salt because they sweat profusely, more than a normal citizen. In such cases, they need a higher sodium intake than the usual recommendations.
Sometimes salt can be serviceable, not just delicious!

In an experiment involving the ever-unfortunate mice, the following steps occurred:
- Mice inoculated with influenza virus
- Th17 cells activated and migrate to respiratory and gastrointestinal systems
- Both respiratory and gastrointestinal tracts have mucosa, so they are similar in a way
- Th17 cells produce cytokines IL-17A and IFN-γ
- These cytokines mess with intestinal bacteria
- Results in less Lacto-, more Entero-
- Intestinal injury

Some people light up joints and some people light up when they hear about joints. Although these are theoretically not mutually exclusive, rheumatologists tend to form the latter group.
In this episode, Dr Allan talks about rheumatology, interesting diseases in the specialty and what it’s like to win an award shaped like a foot.

The U wave is a smaller structure after the T wave that resembles a second T wave, kind of like Baby Mario, M&M’s Minis or Pichu. It’s best seen in V2 and V3.
Prominent U waves are most commonly found in:
Inverted U waves are abnormal and point to cardiac disease.

It’s normal for blood pressure to drop when breathing in.
When you breathe in, the negative intrathoracic pressure increases. That basically means the extra force of all the air you’re leeching from the atmosphere pushes on the insides of the body, squishing the important bits of the cardiovascular system. So, the blood flow gushing out to the rest of the body is reduced a bit, referring to the cardiac output emitting from the left side of the heart. Note that venous return to the right side of the heart increases with inspiration.
A drop in SBP<10 is normal during inspiration. When it’s greater than this, it’s pulsus paradoxus. That can happen in things like:
- inflammatory reaction to parainfluenza virus
- results in airway obstruction, mainly in children because they have smaller airways
- airway obstruction means even bigger negative intrathoracic pressures
- this increases left ventricular afterload, which is the force the heart has to push blood against
- cardiac tamponade
- heart is compressed
- leads to reduced cardiac output

Do the following things, in this order of priority.
- Dehydration – rehydrate with IV fluids
- Insulin – to combat hyperglycaemia
- Electrolytes – potassium shifts are a concern
A simple acronym solves everything. The point is not to let the patient DIE.
Smoked seafood has, unfortunately, been cast into the same category as preserved meats. These traitors have been linked with an increased risk of malignancy. Shun them all!
On the plus side, chicken is still in season(ing). As long as you’re not a greedy pig about it. Moderation, which basically means not over-gorging, is the key to success. That is, health.

Blood vessels are needed to keep the liquid of life pumping throughout our bodies. Bad vessels lead to bad flow, which is undoubtedly a bad thing.
In this episode, Dr Gabrielle talks about vascular surgery, rather interesting stories and workplace injustice.

Opening and closing auditory experiences by Rupert Keller.
The greatest dilemma of any doctor is the colour of stethoscope to acquire. Hue, like the flavour of McDonald’s sundae you select, shows a revealing amount of personality.
