Improves Lung Strength

1 FDA Approves New Cystic Fibrosis Drug

The FDA has approved Kalydeco, a new cystic fibrosis drug that targets a genetic mutation of the disease that affects about 1200 people in the US. About 30,000 Americans have cystic fibrosis, which causes mucus buildup in the lungs and organs. The average lifespan of CF patients is about 37 years. "Even though this drug isn't for the majority of people, it proves that you can look at the mistake in the genes and design a drug in a rational way that will fix the problem," said Dr. Drucy Borowitz, SUNY/Buffalo whose research showed Kalydeco greatly increased lung strength, reduced infections and helped patients gain weight. The drug is approved for patients 6 years and up although manufacturer Vertex plans to study the effects of the drug in those as young as 2 years of age.

May Not Prevent Pregnancy

2 Birth Control Pills Being Recalled

Here’s a little something to get your stress levels up, just in case you didn’t have enough to worry about. Pfizer is recalling about 1 million packets of birth control pills in the United States because there may not be enough contraceptive in them to actually prevent pregnancy. While there are no health risks associated with the recall, Pfizer states that consumers affected by the recall might want to "begin using a non-hormonal form of contraception immediately." The recall involves 14 lots of Lo/Ovral-28 tablets and 14 lots of Norgestrel and Ethinyl Estradiol tablets that might contain an inexact count of inert or active ingredients in the tablets. At this time, the recall doesn’t include any other types of Pfizer contraceptives.

Like Food Poisoning with That?

3 Taco Bell Source of Salmonella Outbreak

The CDC has masked the source of a salmonella food poisoning outbreak last fall, but health officials in Oklahoma are spilling the tacos, pointing fingers at Taco Bell. The CDC doesn't name sources of food contamination unless there's an important public health reason to do so, but state officials in Oklahoma finally agreed to release the information. They revealed that Taco Bell was the source for the outbreak that made 68 people ill in 10 states. Taco Bell isn't taking too kindly to being named as the source of the salmonella poisonings in October and November of 2011, and they're not confessing either. In their statement, Taco Bell said, "They [the CDC] believe that the problem likely occurred at the supplier level before it was delivered to any restaurant or food outlet."

Pattern of Tau Travel Not Random

4 Pathway of Alzheimer's Progression Discovered

Results from Alzheimer's disease studies in mice models show that the tau protein travels from different parts of the brain via neuronal extensions called synapses. Previous studies had pointed to the hypothesis that the disease spreads from region to region. Mice were engineered so that tau would start accumulating in the entorhinal cortex, where it begins in people. Over 22 months, researchers observed that the toxic protein traveled to hippocampus to the neocortex through a linked pathway. All three regions play a role in memories. It is hoped that this knowledge can be used to diagnose and treat Alzheimer's in its early stages by stopping it from spreading. This study also showed that tau protein may be an important target for therapeutic intervention.
