@nicolashery ready for review i worked one the items in this card https://trello.com/c/pw8nT1Bl/40-5-blip-80-20-fixes-to-interaction
Small React tip:

If your component isn't using `this.props.children`...

(Example of a component that *does* use it:)

```html
<Comment showLikes={true}>
  <p>I'm a child of this component</p>
</Comment>
```

..then you don't need the closing tag. It behaves like `<br />`, or `<img />`, etc. In this case:

```html
<NavbarPatientCard
  href={patient.link}
  ...
  patient={patient}  />
```
