We're All the 1 Percent

The U.S. middle class is still incredibly wealthy by international standards.


After 30 years of greed being good and rising tides lifting all boats, inequality -- or "class warfare," if you prefer -- is back on the political agenda.
The Occupiers who camped out in central squares from Melbourne to Oakland, denouncing the "1 percent" for its supposedly ill-gotten gains, have a point: Inequality is out of control. But these mainly middle-class complainers are an incredibly coddled bunch by any international reckoning. This is good news, because we're going to need to tax them more if we're ever going to solve the world's real inequality problem: the estimated 900 million people who live on less than $1.25 a day.
First things first: America's rich are really, really rich. U.S. Census data suggest every man, woman, and child in the top 1 percent of U.S. households gets about $1,500 to live on each day, every day. By contrast, the average U.S. household is scraping by on around $55 per person per day. But the global average is about a fifth of that.
So by global standards, America's middle class is also really, really rich. To make it into the richest 1 percent globally, all you need is an income of around $34,000, according to World Bank economist Branko Milanovic. The average family in the United States has more than three times the income of those living in poverty in America, and nearly 50 times that of the world's poorest. Many of America's 99 percenters, and the West's, are really 1 percenters on a global level./.../

Rheumatic Fever

From: World Heart Federation []

Subject: International Guidelines for Echocardiographic Diagnosis of Rheumatic Heart Disease

World Heart Federation Publishes First International Guidelines for echocardiographic Diagnosis of Rheumatic Heart Disease
Geneva, Tuesday 28 February 2012 – The inaugural international guidelines for the diagnosis of rheumatic heart disease (RHD), a disease that affects tens of millions of people worldwide, have today been published by the World Heart Federation in Nature Reviews Cardiology.
The guidelines define the minimum requirements needed to diagnose RHD in individuals without a clear history of acute rheumatic fever (ARF), and will have important global and national implications.
Diagnosis is conducted with an ultrasound of the heart’s valves and chambers, known as an echocardiogram, but currently no guidelines are available to define what is normal on echocardiography.
In the absence of definitive guidance, physicians reporting on echocardiograms make decisions based on their clinical experience, and missing the disease at an early stage can have devastating consequences.
“The new evidence-based guidelines clearly define not only what is considered to be a definite and a borderline case of RHD but also what is considered normal in children,” said Dr Bo Reményi, Menzies School of Health Research, Darwin, Australia. “The aim of the guidelines is to maximise pick-up of minor degrees of RHD, while preventing over-diagnosis.”
The World Heart Federation echocardiographic criteria for RHD have been developed and formulated on the basis of the best available evidence.
“The use of the guidelines should enable rapid identification of RHD patients who do not have a history of ARF,” said Prof Jonathan Carapetis, a co-author of the guidelines and Director of the Menzies School of Health Research in Darwin, Australia.
Dr Nigel Wilson a co-author and Paediatric Cardiologist from the Starship Children’s Hospital, Auckland New Zealand commented that “the guidelines should also allow for consistent echocardiographic reporting of RHD worldwide, which will in turn help us to get a better understanding of the number of people that are truly affected by this disease.”
Three categories have been defined on the basis of assessment by 2D, continuous-wave, and color-Doppler echocardiography: ‘definite RHD’, ‘borderline RHD’, and ‘normal’. Four subcategories of ‘definite RHD’ and three subcategories of ‘borderline RHD’ exist, to reflect the various disease patterns.

********New aim to detect rheumatic heart disease early

FEBRUARY 28, 2012 Lisa Nainggolan
    Casuarina, Australia - The first evidence-based guidelines on how to use echocardiography to diagnose rheumatic heart disease in those with mild asymptomatic disease have been published, by Dr Bo Reményi (Menzies School of Health Research, Casuarina, Australia) and colleagues in Nature Reviews: Cardiology [1].
The main aim of the new guidelines—which have been written by 21 key researchers in rheumatic heart disease and endorsed by the World Heart Federation (WHF)—"is to allow rapid and early detection of rheumatic heart disease in those individuals who've got mild disease, because they have the most to benefit from early intervention, which is penicillin injections," Reményi told heartwire. Starting this so-called secondary prophylaxis at an earlier stage of the illness than was previously possible can potentially reduce morbidity and mortality, she explained.
The advent of echocardiography has improved the diagnosis of rheumatic heart disease in the past decade—compared with the old method of using a stethoscope—but different criteria to define abnormalities of cardiac valve structure and function have been adopted in various guidances, leading to some confusion, say the researchers.
They hope the development of these new, internationally endorsed standardized diagnostic criteria will help in the design of new studies to evaluate the role of echo in rheumatic heart disease control./.../

Omega-3s May Guard Against Brain Decline

In the first study of its kind, researchers link blood levels of healthy fats to brain size and memory loss.

Eating a diet rich in omega-3 fatty acids — healthy fats found in abundance in oily fish such as salmon — may protect against premature aging of the brain and memory problems in late middle age, according to a study published today in the journalNeurology.
Fish has long had a reputation as a brain food. The new study, however, is the first to link blood levels of omega-3s with brain shrinkage, mild memory loss, and declines in cognitive function, all of which are associated with a higher risk of developing Alzheimer’s disease and other forms of dementia./.../

Avoiding Avoidable Care

COST CONTROL REQUIRES CULTURE CHANGE Until recently, the main framework for thinking about reform has been one of shortages and disparities. That has begun to shift as patients and providers become more aware of the problem of unnecessary or avoidable care. Efforts to improve care and control costs will not be successful unless policymakers, payers, providers, and patients address the problem of avoidable care. Considerable uncertainty remains. How much care in the US is avoidable? Can we quantify its consequences, in terms of financial impact and harms? What factors drive overutili... mais »
