In a study published in the July issue of the journal Stroke, Dr. Mitchell S.V. Elkind found that people infected with Chlamydia pneumoniae were four-and-a-half times more likely to have suffered a first ischemic stroke than their counterparts who had not been exposed to the bacterium.
Columbia University's Institute of Human Nutrition will provide its expertise in nutrition education to the development of online course content for NutritionU.com. Courses will be designed to make practical and understandable nutrition information accessible to a broad audience.
The first health center staffed exclusively by advanced practice nurses officially opened in the Dominican Republic city of Haina, 20 minutes from the capital Santo Domingo.
An abnormality in a protein that helps clear fat from the blood may explain the greatly increased risk of heart disease that people with diabetes face, according to research published by Columbia University College of Physicians & Surgeons colleagues in the Journal of Clinical Investigation (6-00).
Columbia Presbyterian physicians have launched an aggressive project to help Washington Heights/Inwood residents with asthma control their illness and live symptom-free. The Columbia University Asthma Coalition is the first outreach project to target the largely Dominican-American community.
An article in Lancet (6-1-00) explores the story of Evita and her doctor in the context of the mid-20th century, when doctors and families often kept patients in the dark about a diagnosis of cancer, and our present time of apparent openness and patient empowerment.
Columbia University researchers have found that blocking the interaction of two naturally occurring molecules in tumor cells restricts the growth and spread of neoplasms in mice (Nature, 5-18-00).
A Columbia cardiologist has identified a molecular-level malfunction in patients with heart failure that can be repaired with existing treatments (Cell, 5-12-00).
A study by Columbia Presbyterian researchers is the first of its kind to show a significant effect of a new class of drugs that may stabilize progressive, recurrent disease in patients with advanced prostate cancer; results will be presented at the annual meeting of the American Urological Association.
Columbia researchers have participated in a study that points toward a potential treatment for amyotrophic lateral sclerosis, also known as Lou Gehrig's disease (Science, 4-14-00).
HIV-infected patients who respond well to antiretroviral drugs can safely forgo antibiotics to prevent certain opportunistic infections, demonstates a study led by a Columbia researcher (NEJM, 4-13-00).
Columbia University College of Physicians & Surgeons and SUNY Upstate Medical University have received a $28 million grant from the Health Care Financing Administration to bring health care into the homes of underserved rural and inner-city residents with diabetes.
A Columbia Presbyterian neurologist has used an imaging technique called functional MRI to observe the parts of the brain activated in the stroke recovery process, shedding light on how the brain reorganizes itself to restore motor function (Stroke, 3-00).
Levels of two blood factors associated with heart disease risk vary during the course of a woman's menstrual cycle, according to Columbia Presbyterian research.
The "bad" form of cholesterol just got worse. Not only are high levels of the low-density lipoprotein (LDL) form of cholesterol a significant risk factor for heart disease, they also increase a person's risk of developing dementia after a stroke, according to a study.
Researchers have shown that a hybrid molecule can mount a potent, double-sided defense to prevent the death of brain cells following a stroke. The strategy takes advantage of a surprising discovery that injured neurons flag themselves for destruction. The findings are reported in the July 23 issue of Science.
In the long battle against AIDS, investigators have sought a viral Achilles heel by dissecting the precise molecular choreography that unfolds as HIV penetrates the linchpin-like T cells of the immune system. Now, a viral surface glycoprotein caught in the act of binding a CD4 T cell receptor -- graces the covers of both the June 18 issue of Nature and the June 19 issue of Science magazines.
Researchers at the Columbia University College of Physicians & Surgeons have discovered that close relatives of individuals who have colon polyps (non-cancerous growths, or adenomas) face as high a risk of developing colorectal cancer as do people who have relatives with colorectal cancer itself. The research is reported in the June 1 issue of Annals of Internal Medicine.
Two laboratories report the discovery that pacemaker activity in both the heart and the brain is mediated by a common family of novel genes. Pacemaker cells generate rhythmic, spontaneous electrical impulses that can control muscle activity, certain automatic functions such as breathing, and behavioral states, including arousal from sleep. Inappropriate pacemaker activity can lead to both inherited and acquired cardiac arrhythmias, and may also underlie various neurological disorders.
More solid evidence shows that growing up in a home around smokers has an adverse impact on lung function. The strongest correlation, highlighted in a new study, was with mothers who smoked. Girls seem to suffer more than boys, probably because girls spend more time around their mothers, researchers say.
