Diabetics often need to test blood glucose levels several times a day in order to make appropriate decisions about nutrition and, in the case of type 1 diabetics, insulin administration. Medisana, a German company, has developed hardware and an app that allow diabetics to test — and keep track of — blood glucose on an iPhone or iPad. The hardware, called the GlucoDock, connects to an Apple mobile device. The user puts a very small drop of blood on a test strip, and inserts it into the device. GlucoDock, via the VitaDock software, measures blood sugar and records the measurement for personal data tracking purposes.
Body Clock Strength Impacts Bipolar Disorder
Bipolar Disorder, also known as manic–depressive disorder, is a condition characterized by alternating states of elevated energy, cognition and mood, with periods of irritable mood and depression. The extreme mood swings experienced by patients with bipolar disorder have been strongly associated with disruptions in circadian rhythms — the 24-hour cycle of biological processes that govern our day and night activity.
Lithium is one of the most common treatments for bipolar disorder. However, little research has been done to find out if and how lithium impacts the brain and peripheral body clockwork. A new study published in the open access journal PLoS ONE reveals a novel link between lithium, bipolar disorder and circadian rhythms [1].
App Helps Users Maintain Blood Caffeine at Optimal Levels
For many people, a mid-day coffee break helps boost alertness and increase productivity. It turns out there’s a science to coffee-drinking, and it’s more complicated than deciding between a latte and an espresso.
Many Runners Drink Too Much Fluid During Exercise
Popular hydration options among runners and endurance athletes include water and carbohydrate-electrolyte solutions, also known as sports drinks. Sports drink manufacturers, in an effort to sell more product, have convinced a large number of athletes — including accomplished runners — that the key to avoiding medical problems during exercise and racing is to drink as much as possible.
According to new research published in the British Journal of Sports Medicine [1], many runners have erroneous beliefs about their hydration needs, and thus overhydrate by drinking according to a schedule, or drinking “as much as possible.” This increases the risk of exercise-associated hyponatremia, an electrolyte disturbance in which the sodium concentration in the serum is lower than normal. Hyponatremia can cause nausea and vomiting, headache, confusion, fatigue, muscle weakness, cramps, seizures, decreased consciousness and/or coma. With events from community 10K races all the way up to marathons and ultramarathons increasing in popularity among non-elite athletes, understanding public belief about hydration and subsequent hydration behavior is an important public health topic.
