(Press-News.org) New Rochelle, NY, July 12, 2012 –Although acetazolamide is widely prescribed to prevent and treat acute mountain sickness (AMS), the appropriate dose at which it is effective and safe has not been clearly defined. A comprehensive review and meta-analysis of 24 studies comparing the efficacy and risks associated with increasing doses of acetazolamide is published in High Altitude Medicine & Biology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers (http://www.liebertpub.com). The article is available free online at the High Altitude Medicine & Biology (http://www.liebertpub.com/ham) website.
Bengt Kayser and colleagues, University of Geneva, Switzerland, reviewed the data compiled on more than 1,000 subjects and describe the relationship between efficacy in preventing and treating AMS, risk of side effects, and increasing drug dosages. They discuss their findings in the article "Reappraisal of Acetazolamide for the Prevention of Acute Mountain Sickness: A Systematic Review and Meta-Analysis (http://online.liebertpub.com/doi/full/10.1089/ham.2011.1084)."
Unless the baseline risk of AMS is high, as with rapid transport to high altitude (as opposed to a slow ascent), acetazolamide has limited effectiveness. Some side effects occur with even the lowest doses of the drug, whereas others appear to be dose-dependent. The authors suggest that treatment be tailored for the individual depending on AMS risk and acceptability of the most common side effects such as increased urination, numbness and tingling, and taste disturbance.
"This is a valuable contribution on the pros and cons of using the most important medication for preventing and treating acute mountain sickness," says John B. West, MD, PhD, Editor-in-Chief of High Altitude Medicine & Biology and Professor of Medicine at the University of California, San Diego School of Medicine.

Why did Steve Job's death affect people who never knew him?
2012-07-13
New Rochelle, NY, July 12, 2012—The profound sense of loss and public mourning that followed the death of Apple co-founder Steve Jobs was a reflection of how great an impact he had on society and on the lives of individuals through the technology he helped to create. The magnitude and reasons for the outpouring of emotion upon his death by people who did not know him personally are explored in an article in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal published by Mary Ann Liebert, Inc., publishers (http://www.liebertpub.com). The article is ...
Stimulant marketed as 'natural' in sports supplement actually of synthetic origin
2012-07-13
A new study published in the journal Drug Testing and Analysis found that DMAA, a stimulant often found in many nutritional and sports supplements, does not originate from natural substances and is actually comprised of synthetic compounds.
The substance DMAA (1,3-dimethylamylamine) is a stimulant existing in various pre-workout supplements and often labeled as part of geranium plants. The safety and origin of DMAA in these supplements is often the subject of intense debate and has been recently linked to the death of two U.S. soldiers, causing the Army to pull the supplement ...
Caterpillar gets more from its food when predator is on the prowl
2012-07-13
WEST LAFAYETTE, Ind. - Animals that choose to eat in the presence of a predator run the risk of being eaten themselves, so they often go into a defensive mode and pay a physical penalty for the lack of nutrients.
But that's not so for the crop pest hornworm caterpillar, a study shows.
While other animals increase metabolism and stop growing or developing during a defensive period, hornworm caterpillars slow or stop eating but actually keep up their weight and develop a little faster in the short term. Ian Kaplan, a Purdue University assistant professor of entomology; ...
Disentangling information from photons
2012-07-13
Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography and quantum computing. The findings, published in EPJ D¹, are so robust that they enable access to the information even when the measurements on photon pairs are imperfect.
The authors focused on photon pairs described as being in a state of quantum entanglement: i.e., made up of many superimposed pairs of states. This means that these photon pairs ...
Study questions whether becoming a doctor pays off for women
2012-07-13
Women who go to medical school just for the financial rewards of being a doctor could be making a mistake, according to a study published in the Journal of Human Capital.
The research found that after factoring in the high upfront costs of becoming a doctor, most women primary-care doctors would have made more money over their careers becoming physician assistants instead. For the median man on the other hand, becoming a doctor pays a substantial premium over becoming a PA.
Two factors drive the results, say the study's authors, M. Keith Chen and Judith Chevalier ...
Finished heart switches stem cells off
2012-07-13
This press release is available in German.
It is not unusual for babies to be born with congenital heart defects. This is because the development of the heart in the embryo is a process which is not only extremely complex, but also error-prone. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now identified a key molecule that plays a central role in regulating the function of stem cells in the heart. As a result, not only could congenital heart defects be avoided in future, but new ways of stimulating the regeneration of damaged ...
Tamarisk biocontrol efforts get evolutionary boost
2012-07-13
(Santa Barbara, Calif.) –– UC Santa Barbara scientists trying to control the invasive tamarisk plant have been getting a boost from evolution, in the form of a rapidly evolving beetle that has been changing its life cycle to more efficiently consume the noxious weed. Their findings, in a paper titled "Evolution of critical day length for diapause induction enables range expansion of Diorhabda carinulata, a biological control agent against tamarisk," are published in the journal Evolutionary Applications.
"This is one of the clearest cases of rapid evolution," said co-author ...
Plasmonic chains act like polymers
2012-07-13
HOUSTON – (July 12, 2012) – New research at Rice University that seeks to establish points of reference between plasmonic particles and polymers might lead to smaller computer chips, better antennae and improvements in optical computing.
Materials scientists take advantage of strong interactions between chemicals to form polymers that self-assemble into patterns and are the basis of things people use every day. Anything made of plastic is a good example.
Now, Rice scientists have detailed similar patterns in the way that surface plasmons – charged "quasiparticles" ...
Study: Wolverines need refrigerators
2012-07-13
Wolverines live in harsh conditions; they range over large areas of cold mountainous low-productivity habitat with persistent snow. The paper suggests wolverines take advantage of the crevices and boulders of the mountainous terrain, as well as the snow cover to cache and "refrigerate" food sources such as elk, caribou, moose and mountain goat carrion, ground squirrels and other food collected during more plentiful times of year. These cold, structured chambers provide protection of the food supply from scavengers, insects and bacteria. In addition, the refrigerated caches ...
Sports 1, housework, 0
2012-07-13
Pressure to be more involved in their children's lives has many middle class men turning to sports as a way to nurture their kids. This softening of gender roles might be seen on the field, but researchers found it doesn't change traditional behavior at home – where household chores and other parenting responsibilities are still seen as mom's job.
"Women may be unhappy about this inequality, but at the same time they value the fact that their partners are involved with the kids -- even if it is mostly manifested on the soccer field," says Dr. Tamar Kremer-Sadlik, director ...
