KISAH 4 LILIN

Cerita Motivasi dan Inspirasi Nomor 1 - KISAH 4 LILINAda 4 lilin yang sedang menyala. Sedikit demi sedikit habis meleleh. Suasana begitu sunyi sehingga terdengarlah percakapan mereka. Lilin yang pertama berkata: “Aku adalah Damai." "Namun manusia tak mampu menjagaku. Maka lebih baik aku mematikan diriku saja!” Demikianlah sedikit demi sedikit sang lilin pertama padam. Lilin yang kedua berkata: “Aku adalah Iman.” “Sayang aku tak berguna lagi. Manusia tak mau mengenalku. Tak ada gunanya aku tetap menyala.” Begitu selesai bicara, tiupan angin memadamkannya. Dengan sedih giliran lilin ketiga bicara: ”Aku adalah Cinta.” “Tak mampu lagi aku untuk tetap menyala. Manusia tidak lagi memandang dan mengganggapku berguna. Mereka saling membenci. Bahkan membenci mereka yang mencintainya, membenci keluarganya.” Tanpa menunggu waktu lama, maka matilah lilin ketiga. Tanpa terduga… Seorang anak saat itu masuk ke dalam kamar, dan melihat ketiga lilin telah padam. Karena takut akan kegelapan itu, ia berkata: “Eh apa yang terjadi?? Kalian harus tetap menyala. Aku takut akan kegelapan!” Lalu ia mengangis tersedu-sedu. Lalu dengan terharu lilin keempat berkata: "Jangan takut. Janganlah menangis. Selama aku masih ada dan menyala, kita tetap dapat selalu menyalakan ketiga lilin lainnya." ”Akulah HARAPAN.“ Dengan mata bersinar, sang anak mengambil Lilin Harapan, lalu menyalakan kembali ketiga lilin lainnya. Apa yang tidak pernah mati hanyalah HARAPAN. Jangan sampai kita kehilangan HARA....

Why Severe Obesity Is Not a Laughing Matter

Why Severe Obesity Is Not a Laughing Matter

sharma-obesity-risk1Regular readers know that I look at BMI as a rather crappy measure of health – indeed there is very little relationship between mortality and BMI across a wide range of BMI levels.

However, once we approach severe obesity (the most rapidly rising subset of obesity in the population), there is very little doubt that carrying all that extra weight is associated with a substantially increased risk for illness and death.

Just how severely severe obesity affects life expectancy becomes clear from a new analysis by Cari Kitahara and colleagues from the US National Cancer Institute, published in PLOS Medicine.

For their analysis they pooled data from 20 prospective studies from the United States, Sweden, and Australia, sex- and age-adjusted total and cause-specific mortality rates (deaths per 100,000 persons per year) were assessed for people classified as obese class III (BMI 40.0–59.9 kg/m2) compared with those classified as normal weight (BMI 18.5–24.9 kg/m2).

Class III obesity was strongly associated with an increased risk of death due to heart disease, cancer, diabetes, nephritis/nephrotic syndrome/nephrosis, chronic lower respiratory disease, and influenza/pneumonia.

Overall, compared to people with a normal-weight BMI, a BMI of 40–44.9, 45–49.9, 50–54.9, and 55–59.9 kg/m2 was associated with an estimated 6.5, 8.9, 9.8, and 13.7 years of life lost – a substantial amount by any standard.

So, while experts and others may quibble over the value of BMI as a measure of health, there should be little doubt that severe obesity in the BMI 40+ range is associated with a substantial reduction in life expectancy.

All the more reason to increase efforts to better prevent and provide appropriated treatments to people who need them.

In Memorium: Albert (Mickey) J Stunkard

Stunkard twinsAs I spend my days at the 9th Canadian Obesity Network’s Summer Bootcamp for young trainees from Canada and around the world, I was saddened to learn of the passing of Mickey Stunkard, clearly one of the biggest names in obesity research – at a healthy age of 92.

With well over 500 publications to his name, Mickey is perhaps best known for his twin studies showing that the body weight of adopted identical twins reared apart resembles each other and that of their biological parents rather than the weight of their adoptive parents.

This work helped establish the basis for much of the genetic work on obesity that followed, clearly showing that differences in body weight between two individuals are much more accounted for by their difference in genetics than by differences in their “lifestyles”.

These findings were often misused in “nature vs. nurture” debates, an issue that serious scientists have long laid to rest in light of our current understanding that the two cannot be discussed separately, simply because genes and lifestyle interact on virtually every level – from molecules, to cells, to behaviours.

Here is what one obituary had to say about Mickey:

“He surveyed obesity treatment studies in the late ’50s and found that the nation’s diet programs could claim only a 2 percent success rate. He was an early advocate for the use of bariatric surgery to induce weight loss. He also published the first modern account of binge eating in obese individuals.”

I have had to pleasure to often hear him speak at conferences.

He will be dearly remembered.

CON Bootcamp 2014As regular readers will be well aware, each year I attend the Canadian Obesity Network’s Obesity Research Bootcamp, an intense 10-day course for hand-picked young obesity researchers from Canada and around the world.

This year the trainees from Canada (13), Germany (8), Argentina (3), Chile (1), Malaysia (2), Peru (1), Spain (1), USA (1) come from a wide range of research areas – from molecular genetics to health psychology.

Following the opening address by Philip Sherman, Director of the Canadian Institutes of Heath Institute for Nutrition, Metabolism and Diabetes (CIHR-INMD), the course began yesterday with small-group learning sessions on defining and measuring obesity (Ian Jannsen, Queen’s University), weight bias and discrimination (Mary Forhan, University of Alberta), mental health issues (Valerie Taylor, University of Toronto), and energy balance (Eric Ducet, University of Ottawa).

These were complemented by presentations from the trainees on their own work and journal-club style discussion of key papers on relevant issues.

Not least, the camp also encourages networking and discussions that push the trainees to remarkably broaden their perspective on obesity.

I certainly look forward to an intense week at bootcamp.
