A recent international study found that mothers with high lifetime lead exposure may transfer toxic levels of lead to their breastfed infants. The researchers discovered a strong correlation between the amount of lead in the mothers' milk and the corresponding blood lead levels of the infants.
A new study found that a larger angle between an artery and its branching points increases the susceptibility to plaque buildup, leading to cardiovascular disease. Researchers discovered that fluid mechanics plays a crucial role in vessel wall thickening, particularly at lower shear stress areas.
A 51-year-old man with a rare brain disorder, known as 'sagging brain,' was treated at UCSF after initial diagnoses failed to provide relief. Exhaustive neurological scrutiny led to the discovery of a ruptured cyst causing the condition, which was successfully treated through surgery.
A new study published in the Annals of Internal Medicine has found that warfarin, a commonly used blood thinner for older women, does not weaken their bones. The study, which tracked over 6,000 post-menopausal women for two years, found no significant difference in bone thinning or fractures between warfarin users and non-users.
A recent study suggests that extreme fatigue may increase the risk of blood clot formation in the heart arteries, which could lead to future heart attacks. This imbalance is thought to be mediated by impaired fibrinolysis, a process that normally removes blood clots.
Research suggests that hyperbaric oxygen therapy could save millions in treating victims of stroke, epilepsy, and spinal cord injury. The therapy increases blood oxygen levels and may prevent reperfusion injuries by modulating the immune system.
Researchers discovered a possible link between elevated blood homocysteine levels and Alzheimer's disease, with lower folate and vitamin B12 levels also observed. Long-term clinical trials are needed to determine if lowering homocysteine levels can prevent or delay the progression of the disease.
Researchers have found that paraoxonase, an enzyme present in the blood, can prevent the oxidation of LDL cholesterol and reduce atherosclerosis. The discovery opens a possible new route to prevention of heart diseases.
Despite evidence of warfarin's effectiveness, it remains underused to prevent strokes in those with atrial fibrillation. The study found that increased prescriptions from 13% to 40% between 1989 and 1993 did not lead to significant changes in usage from 1993 onwards.
Recent research highlights the strong influence of genes on individual variations in response to diet, influencing predisposition to obesity and atherosclerosis. Genetic analysis may lead to tailored diet plans and drug regimens for heart disease and stroke prevention.
A recent study published in Circulation found that consuming garlic supplements can lower the stiffness of the aorta by up to 15% in healthy individuals. The study suggests that eating garlic may be beneficial for cardiovascular health, particularly as people age.
A new study found that insulin therapy is largely ineffective in achieving tight blood sugar control in people with type 2 diabetes. The study suggests that most patients need more aggressive treatment to reach near-normal blood sugar levels and highlights the need for a revised standard of care.
A study found that physical exertion, even mowing the lawn, can rupture blood clots in vulnerable plaque of sedentary men with coronary heart disease and hypercholesterolemia. This increases the risk of sudden coronary death, especially for those with high total cholesterol levels.
Researchers have discovered that saliva is a reliable source of genetic material for DNA screening, eliminating the need for blood samples and associated risks. This breakthrough could make genetic testing more accessible to populations previously outside the medical mainstream.
Researchers found that low-frequency ultrasound enhances the effectiveness of thrombolytic drugs in dissolving blood clots deep within the brain. This combination therapy may reduce the duration and doses of medication needed, minimizing risks of bleeding and other complications associated with stroke treatment.
A new study reveals striking fluctuations in blood cholesterol levels among children and teenagers, suggesting that normal cutpoints for testing may need to be revised. The study found that boys' body fatness levels decrease as they mature, while girls' body weight increases with minimal changes in body fat percentage.
The program, now in its second year, provides four weeks of intensive speech therapy for adults aged 20-50. Participants learn skills and behaviors to overcome stuttering, such as awareness, acceptance, and preparatory techniques like rehearsal and prevoicing. The goal is to improve communication flow and reduce stuttering interruptions.
A low-fat diet is safe for children aged 4-10 if parents follow the Food Pyramid guidelines and provide counseling or education, reducing the risk of heart disease. The study found that children on modified diets had adequate intakes of all nutrients while lowering their LDL blood levels.
Researchers found that men with high homocysteine levels and Factor V Leiden were three times more likely to develop venous blood clots. A 20-fold increased risk was seen in those with both conditions.
A new laser therapy, transmyocardial revascularization (TMR), has been found to be effective in reducing chest pain in patients with coronary artery disease. The procedure creates new blood-carrying channels in the heart muscle, improving oxygen supply and reducing symptoms.
A new screening test can identify stroke victims in three minutes and facilitate faster treatment with clot-busting drugs. The Los Angeles Paramedic Stroke Screen has been shown to correctly diagnose ischemic strokes in 93% of cases, shortening time to actual treatment by an average of 90 minutes.
A study published in Circulation found that smoking causes the aorta to stiffen, reducing its ability to relax and widen. This can lead to increased pressure on the left ventricle, which pumps blood throughout the body.
A temporary metal filter successfully caught a life-threatening blood clot in a bedridden patient, preventing catastrophic lung damage. The procedure, performed by Johns Hopkins physicians, marks the first use of the filter in the US and holds potential for thousands of accident victims.
The NHLBI is launching a 5-year, $30 million study to investigate the safety and effectiveness of cord blood transplantation as an alternative to bone marrow transplantation for various cancers, blood diseases, and genetic disorders. The study aims to provide answers to scientific and ethical questions surrounding this procedure.
Researchers developed CLOTSIM, a computer model simulating blood clot dissolution, to provide critical information on thrombolytic agents. The program helps predict clinical outcomes and tailor therapies to reduce patient risks.
A study from Ohio University predicts which donors are more sensitive to medical procedures, enabling stress-reducing techniques to be applied. The 10-question form identifies high-risk donors, who can benefit from shorter questionnaires and targeted interventions.
