Health Watchdog recommends improved monitoring of painkiller useThe Care Quality Commission has urged professional bodies of doctors for drawing up guidance on the appropriate prescribing of painkillers and amphetamines amid their growing use on patients by health professionals.

The commission also warned that “safety gains” attained during the last three years “are not lost in the current drive to save costs”.

It is important to note here that more and more drugs are being prescribed by health workers other than doctors, including nurses and pharmacists.

Substance loss related to nervous system complications can be reversed by steroids

Posted By

Substance loss related to nervous system complications can be reversed by steroidsScientists from the University of Illinois have reported that steroids can be more than just useful for reducing inflammation. It was disclosed that use of steroids can lead to reversal of a loss of myelin, which is a major problem in multiple sclerosis and other demyelinating diseases and injuries associated with the central and peripheral nervous systems.

It was further reported that steroids dexamethasone and progesterone can actually signal the initiation and dramatically increases in context of the rate of myelin synthesis.

The new findings were published in a biochemistry section of the Proceedings of the National Academy of Sciences.

Serotonin and altered signaling reduced with use of steroidsParents and researchers have been expressing concerns after more than one in ten boys admitted to use of anabolic steroids and performance enhancing drugs over the last decade. To add to the woes, the physiological and neurological effects in the long term associated with such use have not been fully examined in the past.

A new research from Northeastern University that was published in an issue of the journal Pharmacology, Biochemistry and Behavior has documented the association between adolescent anabolic steroid use and aggression. The research also suggested that an association between the increases in aggression with deficits in the brain’s serotonin system.

This research was funded by the National Institute of Health.

Long term aggression triggered by use of anabolic steroids

Posted By

Long term aggression triggered by use of anabolic steroidsNortheastern University psychology professor Richard Melloni, after studying the association between use of steroids and aggression, has recently found evidence suggesting that use of anabolic steroids could possibly have long-term effects on aggression and behavior levels well after steroid users have stopped abusing these performance enhancing drugs.

Melloni was of the view that athletes abusing steroids can also be inclined towards aggressive behavior long after their abuse of drugs has waned.

The research was funded by the National Institutes of Health (NIH), one of the world’s foremost medical research centers.

Identification of cells mediating steroid-resistant asthma

Identification of cells mediating steroid-resistant asthmaCells that could possibly play an important role in some forms of steroid-resistant asthma, a complication of the condition that makes treatment even more challenging, have been identified by researchers at Children’s Hospital of Pittsburgh of UPMC.

Study’s senior author, Jay K. Kolls, MD, chief of the Division of Pediatric Pulmonary Medicine, Allergy and Immunology at Children’s Hospital, remarked that the identification of a lineage of cells called as T Helper Type 17 (Th17) could assist scientists in developing new treatments for exercising a better control on the disease.

The study was published in an issue of the Journal of Immunology.

Kidney damage likely with bodybuilding steroidsAthletes making use of performance enhancing or bodybuilding steroids could gain muscle mass and body strength but may risk kidney function. This finding was disclosed by a presented paper at the American Society of Nephrology’s 42nd Annual Meeting and Scientific Exposition in San Diego, CA.

It is worthwhile to note here that reports of athletes abusing anabolic steroids are increasingly becoming common these days.

It was suggested by the findings that habitual and long-term use of steroids has severe effects on the kidneys, a fact that was not recognized till now.

Natural defense mechanism against heart disease identified

Natural defense mechanism against heart disease identifiedAccording to researchers at the University of Leeds, a natural defense mechanism against heart disease can be switched on by steroids sold as health supplements.

Biologists at the University of Leeds were able to identify a previously-unknown ion channel in human blood vessels that could possibly inhibit the production of proteins (cytokines) driving the early stages of heart disease.

The research suggested that expected benefits of ‘fountain of youth’ steroids will be much greater if they are used in a combination with healthy lifestyle strategies such as diet and exercise or cholesterol-reducing drugs.

Airway constriction in asthmatic women patients reduces with estrogen

Airway constriction in asthmatic women patients reduces with estrogenAccording to new bench research from the Mayo Clinic, female sex hormones could work with beta-agonists in minimizing airway constriction.

Lead student researcher, Elizabeth A. Townsend, of the Mayo Clinic Department of Physiology and Biomedical Engineering, said that it will be of interest to ascertain whether sex steroids such as estrogen and progesterone play a role in modulation of airway tone.

The findings are being presented at the ATS 2010 International Conference in New Orleans.
