Reference excerpt

Sherry Hsiang-Yi Chou is a Canadian neurologist and an Associate Professor of Neurology and Chief of Neurocritical Care at the Northwestern University Feinberg School of Medicine and Northwestern Medicine. She is a Fellow of the Neurocritical Care Society and the Society of Critical Care Medicine. During the COVID-19 pandemic Chou assembled a worldwide team of physicians and scientists to better understand the neurological impacts of COVID-19, forming the Global Consortium Study of Neurologic Dysfunction in COVID-19 (GCS-NeuroCOVID). The first report of this large, multicenter, multicontinent consortium found that neurological manifestations are present in 8 out of 10 adult patients hospitalized with COVID-19 and are associated with increased mortality.

Early life and education Chou studied mathematics and physics at McGill University. She remained there for her medical degree, which she completed in 2001. Chou completed medical internship at Beth Israel Deaconess Medical Center and residency in Neurology followed by fellowship in stroke and neurocritical care at Massachusetts General Hospital and Brigham and Women's Hospital. Chou completed a master's degree in clinical translational research at Harvard Medical School in 2009. Following completion of training Chou remained on faculty at Brigham and Women's Hospital, where Chou worked on numerous large clinical trials such as the Antihypertensive Treatment of Acute Cerebral Hemorrhage-II (ATACH-II) research protocol, which looked to identify the therapeutic benefit of intensive blood pressure treatment in intracerebral haemorrhage patients. She worked at Brigham for several years, holding a simultaneous faculty position at the Harvard Medical School.

Research and career Chou was appointed to the University of Pittsburgh in 2014. Her research and practise looks to improve the treatment of critically ill patients who suffer from haemorrhagic brain injury. Chou has a particular focus on subarachnoid haemorrhage (SAH) and the identification of novel biomarkers. She studies how the inflammation that occurs after SAH can result in secondary brain injury, and how this impacts recovery. To do this, Chou monitors microRNA biomarkers of systemic inflammation. She created a biobank of samples collected over the course of patients' time in hospital. This data allowed Chou to identify a specific inflammation biomarker that is only detectable in the early days of brain injury. During the COVID-19 pandemic it emerged that in certain cases, the viral infection resulting from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause a rare type of encephalopathy. These observations were first observed in Wuhan, and subsequently across Europe and the United States. The overreaction of the immune system in response to SARS-CoV-2 infection triggers a cytokine storm, whereby immune cells and cytokines are excessively produced. Cytokine overproduction can cause small haemorrhages in the brain. Whilst the neurological symptoms related to COVID-19 are rare, Chou argued that physicians needed to crowdsource their observations to provide better care. COVID-19 may its way upward to the brain through the nose and olfactory bulb, which may explain the anosmia. The Centers for Disease Control and Prevention (CDC) added "new confusion or inability to arouse" to their COVID-19 emergency warning signs, which means that people who show these symptoms must seek medical attention immediately. Through her work with the Neurocritical Care Society, Chou has since established a world-wide consortium of researchers to track the prevalence of neurological complications in hospitalised COVID-19 patients.

Worked examples

Example 1 — a first encounter with Sherry Chou

Start with the simplest possible case. Write down what Sherry Chou claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sherry Chou before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sherry Chou ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sherry Chou

In research: Sherry Chou appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sherry Chou in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sherry Chou is common in secondary-school and first-year university syllabi. It links to neighbouring topics COVID-19 researchers, Canadian women neuroscientists, Harvard Medical School alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Sherry Chou outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
