Yes, The Calorie Is Broken. Here's Why.

“For me, a calorie is a unit of measurement that’s a real pain in the rear.” Bo Nash is 38. He lives in Arlington, Texas, where he’s a technology director for a textbook publisher. And he’s 5’10” and 245 pounds – which means he is classed as obese. In an effort to lose weight, Nash uses an app to record the calories he consumes and a Fitbit band to track the energy he expends. These tools bring an apparent precision: Nash can quantify the calories in each cracker crunched and stair climbed. But when it comes to weight gain, he finds that not all calories are equal. How much weight he gains or loses seems to depend less on the total number of calories, and more on where the calories come from and how he consumes them. The unit, he says, has a “nebulous quality to it”. Tara Haelle is also obese. She had her second son on St Patrick’s Day in 2014, and hasn’t been able to lose the 70 pounds she gained during pregnancy. Haelle is a freelance science journalist, based in Illinois. She understands the science of weight loss, but, like Nash, doesn’t see it translate into practice. “It makes sense from a mathematical and scientific and even visceral level that what you put in and what you take out, measured in the discrete unit of the calorie, should balance,” says Haelle. “But it doesn’t seem to work that way.” Nash and Haelle are in good company: more than two-thirds of A...

One of the fundamental distinctions we need to make when working with people who experience pain is to understand the difference between experiencing pain – and the behaviour or actions or responses we make to this experience. This is crucial because we can never know “what it is like” to experience pain – and all we have to rely on as external observers is what we see the person doing. Differentiating between the various dimensions associated with our experience of pain makes it far easier to address each part in the distinct ways needed. Let me explain. We know the current definition of pain &ndas...

Antiphospholipid Syndrome (APS) important in vascular medicine as well as obstetrics. In obstetrics, it is important because it can cause fetal loss, intrauterine growth retardation and severe preeclampsia. In vascular medicine it is important because it can cause thrombotic events which could be arterial, venous or microvascular [1]. It can also be accompanied by moderate thrombocytopenia [2]. Thrombotic events involving multiple organs may be termed catastrophic Antiphospholipid Syndrome [3]. APS is an autoimmune disease with antibodies directed against beta2 glycoprotein I. This leads to suppression of tissue fact...

It is needless to say that heart disease in pregnancy is a challenge for the obstetrician and the cardiologist. Hemodynamic changes in pregnancy and labour can adversely affect many of the significant cardiac lesions. Increase in blood volume and heart rate are the important factors during pregnancy. In general stenotic lesions and pulmonary hypertension are poorly tolerated, while regurgitant lesions are better tolerated. Specific risks like aortic dissection and rupture are there for coarctation of aorta. Several risk stratification schemes have been developed for assessing the risk of pregnancy with heart disease over ...
