Ebola and Quarantine

New England Journal of Medicine

The governors of a number of states, including New York and New Jersey, recently imposed 21-day quarantines on health care workers returning to the United States from regions of the world where they may have cared for patients with Ebola virus disease. We understand their motivation for this policy — to protect the citizens of their states from contracting this often-fatal illness. This approach, however, is not scientifically based, is unfair and unwise, and will impede essential efforts to stop these awful outbreaks of Ebola disease at their source, which is the only satisfactory goal. The governors’ action is like driving a carpet tack with a sledgehammer: it gets the job done but overall is more destructive than beneficial.

Are Ebola Quarantines Necessary?

To Improve a Memory, Consider Chocolate

New York Times

In a small study in the journal Nature Neuroscience, healthy people, ages 50 to 69, who drank a mixture high in antioxidants called cocoa flavanols for three months performed better on a memory test than people who drank a low-flavanol mixture. On average, the improvement of high-flavanol drinkers meant they performed like people two to three decades younger on the study’s memory task, said Dr. Scott A. Small, a neurologist at Columbia University Medical Center and the study’s senior author. They performed about 25 percent better than the low-flavanol group.

Cocoa Constitutents Fend Off Senior Moments. The Memory of a 30-Year-Old?

Ebola’s Quarantine Politics: Why Authorities Push Voluntary Isolation

National Geo

Aside from four people who shared an apartment with Duncan in the early days of his illness, the U.S. government has kept all quarantines voluntary. The fact that those four did not fall ill despite their exposure shows that casual contact, such as sharing an airplane, with someone before they are significantly symptomatic carries very little risk, said Amy Fairchild, a professor of sociomedical sciences at Columbia University’s Mailman School of Public Health in New York City.

How to Quarantine Against Ebola

New York Times

There is a fourth strategy, although it will need to be evaluated and deployed carefully. Since the 1990s, novel methods have allowed doctors to detect viruses in the pre-symptomatic phase of an infection, often with remarkable sensitivity and precision. One of these involves the polymerase chain reaction, or P.C.R., a chemical reaction that amplifies pieces of a virus’s genes floating in blood by more than a millionfold, which is what makes early, pre-symptomatic infections identifiable.

Despite the hype, no verdict yet on high-fat, low-carb regime

Reuters Opinion

Low-carb diets have been advocated by various “experts” for at least 225 years. Many sources credit John Rollo with being the first to promote a low carbohydrate diet for diabetics in the late 1700s. In the 1860s, an English undertaker by the name of Banting published his famous “Letter on Corpulence, Addressed to the Public.”  His diet, which advocated giving up several starchy foods, was so popular that for decades dieting was actually called “Banting.”
