Currently, more than 33 million people worldwide are living with human immunodeficiency virus (HIV) infection. Each year, there are nearly 3 million new infections. The growing worldwide burden of this infection, which causes acquired immune deficiency syndrome (AIDS), has prompted researchers to investigate novel approaches to infection control and prevention. A recent investigation published by the New England Journal of Medicine, which will likely be known as a landmark study in HIV/AIDS research, reported that a daily dose of a prophylactic pill can prevent the spread of HIV before exposure to the virus.
The tightly regulated balance between secretion and removal of neurotransmitters is not functioning properly in certain mental conditions like bipolar disorder, obsessive-compulsive disorder, anxiety, and depression. Neurotransmitters are signaling molecules used to transmit messages between neurons (nerve cells) in the brain. Serotonin is one of the neurotransmitters affected in depression and similar disorders. The most common class of drugs for the treatment of these conditions is called selective serotonin reuptake inhibitors (SSRI). The well-known Fluoxetine (Prozac) is a member of this class.
A new study investigating the effects of fish oil on depression has helped cement omega-3 fats as one of the most effective natural approaches to depression. A new research study published in the Journal of Clinical Psychiatry was one of the first to put fish oil’s potential depression-battling benefits through the rigor of a randomized control trial. If these results are repeated in future studies, it could provide relief to the twenty one million adults who struggle with depression and side effect laden antidepressant medications.
The word comes from the Greek “boulimia,” for bous (ox) plus limos (hunger). Bulimia is ox hunger, which could mean something like “hungry as a horse.” In practice, it means “to gorge.” It is also known as bulimia nervosa, or binge-purge syndrome. Bulimia is a disorder marked by the consumption of large amounts of food over a short period of time, followed by “compensatory behavior,” usually in the form of vomiting, to rectify this loss of control. It is often grouped with anorexia, and while the two conditions share many symptoms --abnormal food consumption patterns, body image distortion, anxiety -- none is stranger than the ailment clinicians have dubbed “body dysmorphic disorder” or BDD. People with this disorder feel deeply unattractive because of a perceived flaw in skin, hair, or facial features -- minor flaws at best, or defects which demonstrably are not there -- and cannot be reasoned out of this core belief. What they see in the mirror is simply different from what others objectively see about them.
