Bone densitometry scans may be a novel, noninvasive, and scalable way to identify older women at risk of developing dementia, new research suggests. In an analysis of more than 900 study participants, women in their 70s with more advanced abdominal aortic calcification (AAC) seen on lateral spine images during dual-energy x-ray absorptiometry (DEXA) had a two- to fourfold higher risk for late-life dementia than those with low AAC. This finding was independent of cardiovascular risk factors and apolipoprotein E (APOE ) genotype.

RE: Final Frontier of AI in Clinical Diagnostics Getting Closer
@amitesh The optimism was nevertheless leavened with warnings over machine learning systems being only ever as good as the data they are built on, and the unknowable nature of automated algorithm development, which could have unforeseen consequences if, as is already the case, relatively untested systems are used in clinical situations. nobody is actually suggesting that AI or deep leaning or whatever you want to call it, is actually going to take over from humans, but instead it will form a symbiosis with clinicians to help them in focusing on where they can make the greatest difference.
RE: Deep Venous Thrombosis Prophylaxis in Orthopedic Surgery !
@atharva Many pharmacologic agents are currently available to prevent thrombosis. Agents that retard or inhibit the process belong under the general heading of anticoagulants. Agents that prevent the growth or formation of thrombi are properly termed antithrombotics and include anticoagulants and antiplatelet drugs, whereas thrombolytic drugs lyse existing thrombi. There is some evidence to suggest that statins have the potential to reduce recurrent events in patients with VTE. For the importance of prevention, see Hull and Pineo's 1998 study.
RE: Hypertensive Emergencies and Target Organ Damage!
@sampurno The clinical presentation is easily classified according to the target organ involved. Single-organ involvement is found in approximately 83% of patients presenting with hypertensive emergencies. Two-organ involvement is found in 14% of patients, and multiorgan involvement (>3 organ systems) is found in approximately 3% of patients presenting with a hypertensive emergency. During hypertensive emergencies, the left ventricle is unable to compensate for an acute rise in SVR. This leads to left ventricular failure and pulmonary edema or myocardial ischemia. Chronic hypertension increases arterial stiffness, increases systolic BP, and widens pulse pressures. These factors decrease coronary perfusion pressures, increase myocardial oxygen consumption, and lead to the development of left ventricular hypertrophy (LVH). In LVH, the myocardium undergoes structural changes in response to increased afterload. Cardiac myocytes respond with hypertrophy, allowing the heart to pump more strongly against the elevated pressure. However, the contractile function of the left ventricle remains normal until later stages. Eventually, LVH reduces the chamber lumen, limiting diastolic filling and stroke volume. The left ventricular diastolic function is markedly compromised in long-standing hypertension.
RE: Can I take iron supplement for pernicious anemia?
@nipa There is no role of iron supplements here. High-dose oral vitamin B12 supplementation may be an effective option for some people with pernicious anemia as well. In people with vitamin B12 deficiency anemia where the body can absorb vitamin B12, oral vitamin B12 supplementation and diet adjustments may be an effective treatment.
RE: Does garlic really help in osteoarthritis?
@japmaan Garlic is a tasty addition to just about any savory dish. Like onions and leeks, it contains diallyl disulfide, an anti-inflammatory compound that limits the effects of pro-inflammatory cytokines. Therefore, garlic can help fight inflammation and may even help prevent cartilage damage from arthritis.
Tip: Opt for fresh garlic from the produce section of your market. Preservatives may be added to bottled garlic and processing, which may decrease some of its strength.
RE: I am getting abdominal pain, what should I do?
@milan The treatment for abdominal pain depends on its cause, and may include:
Medications to lower inflammation, prevent acid reflux, or treat ulcers or infection
Surgery to treat a problem with an organ
Over-the-counter pain relievers like aspirin and ibuprofen can irritate your stomach and worsen your pain. Don’t take them unless a doctor has diagnosed the cause of your belly pain and recommends their use.
Some diet and lifestyle changes may help belly pain caused by gas and indigestion. Here are some things you can try:
Eat smaller portions at more frequent meals
Chew your food well
Drink beverages at room temperature
RE: Is it good to have multivitamin tablets randomly?
@jiniya With three new studies finding that a daily multivitamin won't help boost the average American's health, the experts behind the research are urging people to abandon use of the supplements. The studies found that popping a daily multivitamin didn't ward off heart problems or memory loss, and wasn't tied to a longer life span. In a strongly worded editorial on the three studies, Guallar and his co-authors urged people to stop spending money on multivitamins. Even a representatives of the vitamin industry asked people to temper their hopes about dietary supplements.
RE: I am suffering from food poisoning, what should I do?
@natasha In most cases, there isn’t much your doctor can specifically do for you, and you get better on your own within a few days. Adults or children who lose a lot of fluids -- this is called dehydration -- may need to go the hospital to get an IV. This will replace your fluids and electrolytes more quickly. For severe food poisoning caused by certain bacteria, such as listeria, you may get antibiotics. But with most bacteria, you may not get any medication unless you have a weak immune system or you’re pregnant. You may also get medicine for food poisoning caused by parasites. For viruses, there’s nothing you can take.
