No Reports of Serious Damage

1 Earthquake Hits Mexico

An earthquake with a magnitude of 7.6 hit Mexico today, rattling residents in Mexico City, the nation’s capital. The US Geological Society reported that the epicenter was about 15 miles east of Ometepec, Guerrero and about 115 miles east of Acapulco where residents and visitors reported feeling tremors. Mexico City Mayor Marcelo Ebrard said there was no visible damage in the city but numerous buildings were evacuated. There have been no immediate reports of serious damage, according to Mexican President Felipe Calderon. Mexico City is home to more than 20 million residents and because it’s built on volcanic ash and clay, is vulnerable to earthquakes. In 1985, 10,000 people lost their lives when a massive earthquake hit the city.

Going Up, Ward off Headache

2 Ibuprofen May Help Prevent Altitude Sickness

Taking ibuprofen may help prevent altitude sickness, finds a small study. Published in Annals of Emergency Medicine, the study found that people who took four doses of 600 milligrams of ibuprofen during a 24-hour period were less likely to develop altitude sickness than people taking a placebo during the period of ascending to 12,570 feet above sea level. It's believed that the anti-inflammatory properties of ibuprofen help prevent symptoms like headaches at high altitudes. CNN reports that 43 percent of people who took ibuprofen during ascent developed altitude sickness, while 69 percent of those who took a placebo developed symptoms of the condition, including nausea, dizziness and fatigue.

When It's Good to Be Heavy

3 Thin People More Likely to Die After Surgery

People with a body mass index (BMI) of 23 or less were 40 percent more likely to die following surgery compared with people who were overweight with a BMI from 26 to 29, say researchers. Reported in Archives of Surgery, the study found that slender people were more likely to die within a month after a surgical procedure. Researchers accounted for the condition that led to the surgery and the risk of death associated with the surgery, but the increased risk for skinny people remained. MSNBC says that the findings agree with many other recent studies, including a study published this month in the Journal of Cardiothoracic and Vascular Anesthesia, which found that 20 percent of underweight people having coronary artery bypass died in the hospital, compared with 3 percent of obese patients.

Sleepy by State

4 Southerners Have More Trouble Sleeping

People living in the South have more trouble falling asleep and staying asleep, plus they're more likely to feel tired during the day, say researchers. Published in Journal of Clinical Sleep Medicine, the findings from researchers at the University of Pennsylvania Center for Sleep and Respiratory Neurobiology reveal that California residents were the best rested with only 17 percent reporting sleep troubles and only 18 percent experiencing daytime fatigue. By contrast, one-third of adults in West Virginia and Mississippi felt sleepy during the day, and about a quarter of people in Arkansas and Louisiana had daytime fatigue. MSNBC reports that researchers aren't sure why geography plays a role in sleep quality, but they think that stress could be a factor.

Smells for Portion Control

5 Food Aroma Influences Bite Size

Food aroma influences bite size when eating, and may make a difference in portion size consumed, suggest Dutch researchers. Published in the journal Flavour, the study found that the intensity of a food's aroma influences the first bite and additional bites. The stronger the smell of food, the smaller the bite size. Small bite size is associated with feeling full and with eating foods that are unfamiliar or disliked. Study findings suggest that manipulating food aroma may result in a 5 to 10 percent decrease in intake per bite. Researchers believe that combining aroma control with portion control might possibly make people think they're full with a smaller amount of food.

I'm Ready Now, Make Me Smart

6 Feeding Baby on Demand May Help IQ

Kids who were fed on demand instead of by a set schedule have higher IQ scores, say researchers. The new study compared the IQ scores of eight-year-old kids who were demand-fed as infants with schedule-fed kids. Whether fed by bottle or breastfed, kids who were fed on demand as babies had IQ scores that were between four and five points higher than kids fed on a schedule. Published in European Journal of Public Health, this is the first large-scale study that looks at the long-term outcome of feeding on a schedule versus feeding by demand. Researchers say that more study is needed before parents make feeding changes for the sake of IQ.

Running Memory Away

7 Cops May Suffer Memory Loss After Chases

Police officers who chase a suspect or engage in a physical altercation may forget important details of the incident, suggest researchers. Reporting in Psychological Science, the researchers say that cops who engage in at least a minute of intense physical energy during an altercation could suffer memory loss. CNN reports that the study's lead author, Dr. Lorraine Hope of the University of Portsmouth in the UK, says that the findings are a "warning" to law enforcement and the court system. Hope says that officers are expected to remember details of physical struggles, but it may be very difficult for them to do. The study involved 52 police officers (42 men and 10 women) in Canada.

Dizzy Now, Heart Failure Later?

8 Being Lightheaded May Signal Heart Problems

A new study has demonstrated that people who develop sudden hypotension, or low blood pressure, when standing up may be at an increased risk of developing heart failure. This condition is called orthostatic hypotension. Over 12,000 people aged 45 to 64 years were followed during the study and about 11 percent of those with the condition from the start developed heart failure compared to 4 percent that did not. One hypothesis is that people with orthostatic hypotension may have early stage atherosclerosis, the accumulation of plaque in the arteries. The results do not indicate a cause and effect but it may prompt doctors to be more vigilant about watching for heart failure. To test your orthostatic blood pressure, your doctor will take it twice, one lying down and then after standing up.

When Pain Meds Are the Headache

9 Pain Relievers May Cause Hypertension

A new study suggests pain relievers such as Ibuprofen increase blood pressure (BP), a major risk factor in heart attacks, strokes and aneurisms and may interfere with BP-lowering drugs. A lot of over-the counter and commonly used prescription drugs can cause hypertension and include hormonal contraception, anti-depressants, and anti-inflammatory medications and antibiotics. It is important that doctors consider this side effect when prescribing medications and can lower the risk by reducing the dosage or adding on an anti-hypertensive drug. Benefits also have to be considered, such as using anti-vascular endothelial growth medications that prevent solid tumors from creating new blood vessels. They can increase BP, the goal is to kill the tumor and increase the patient’s survival.

Challenges Oral Food Challenge

10 Blood Test May Better ID Peanut Allergy

Researchers at Murdoch Children’s Research Institute have developed a blood test to diagnose peanut allergies in hopes that it is cheaper and easier than the oral food challenge, currently the standard. The oral food challenge gives a clear answer but takes a lot of time, is expensive and puts patients at risk of anaphylaxis. Performing two tests using blood and the Arah2 protein from peanuts led to a 4 fold reduction in performing the oral food challenge. This would also alleviate wait times at allergy clinics because general practitioners could simply order a blood test and reduce over diagnosing because of “possible positives.” A peanut allergy diagnosis is usually clear cut, but that is not always the case in kids without an obvious history or who have not been exposed to them.
