Restraint technique could be fatal: Forcing a detainee to bend over while seated can lead to death

Researchers found that the hold, forcing a detainee to bend over while seated, can massively cut lung capacity.

They placed 40 volunteers in chairs and then leaned them forward, bringing their face close to the lap. They used arm holds and applied a small amount of force to prevent the volunteer from attempting to return to a normal sitting position. In the worst cases, the lungs' capacity was almost halved.

"Imagine that from the perspective of the security staff. They feel you struggle and they will feel that you are getting angry. They will apply more force to manage your resistance. It becomes a vicious circle."

7 healthy traits linked to lower death risk but only 2% of people have all 7 - are you one of them?

People who meet the 7 healthy goals recommended by the American Heart Association are less likely to die of cardiovascular causes.

Here there are:

- not smoking
- moderate exercise at least 5 times a week
- untreated blood pressure under 120/80
- HbA1c under 5.7%
- total cholesterol under 200 mg/dL
- BMI less than 25
- a diet high in produce, fish, and whole grains, and low in sodium and sugary beverages

Less than 2% of people reached all 7 ideals.

Those who met 6-7 goals had reduced risks for all-cause mortality (hazard ratio, 0.49), compared with participants meeting zero or one goal.

C-reactive protein (CRP) associated with risk of coronary heart disease, stroke, vascular mortality, and death from several cancers and lung disease

Associations of C-reactive protein (CRP) concentration with risk of major diseases can best be assessed by long-term prospective follow-up of large numbers of people.

This Lancet meta-analysis included records of 160,309 people without a history of vascular disease from 54 long-term prospective studies.

Risk ratios (RRs) were 1·23 for coronary heart disease; 1·32 for ischaemic stroke; 1·34 for vascular mortality; and 1·34 for non-vascular mortality.

CRP concentration has continuous associations with the risk of:

- coronary heart disease
- ischaemic stroke
- vascular mortality
- death from several cancers and lung disease

The relevance of CRP to such a range of disorders is unclear. Associations with ischaemic vascular disease depend considerably on conventional risk factors and other markers of inflammation.

Is is still a topic of debate is whether CRP has a causal role in the development of cardiovascular disease.

However, even if CRP might not be involved in the causal pathway of atherogenesis and plaque rupture, it may still be a valuable tool in cardiovascular medicine.

In primary prevention, lovastatin therapy was more cost effective in people with increased CRP concentrations.

The JUPITER trial recently showed that, in people with relatively normal LDL cholesterol concentrations and CRP higher than 2 mg/L, rosuvastatin reduced cardiovascular risk. Even if CRP turns out to be not directly causal in cardiovascular disease, it might be useful to identify individuals at cardiovascular risk and to evaluate the efficacy of our preventing and therapeutic interventions.

3-gram reduction in daily salt intake would decrease coronary heart disease, stroke, and death

The U.S. diet is high in salt, with the majority coming from processed foods. Reducing dietary salt is a potentially important target for the improvement of public health.

Reducing dietary salt by 3 g per day (1200 mg of sodium per day) is projected to reduce the annual number of new cases of CHD by 60,000 to 120,000, stroke by 32,000 to 66,000, and myocardial infarction by 54,000 to 99,000 and to reduce the annual number of deaths from any cause by 44,000 to 92,000. Such an intervention would be more cost-effective than using medications to lower blood pressure in all persons with hypertension.

The cardiovascular benefits of reduced salt intake are on par with the benefits of population-wide reductions in tobacco use, obesity, and cholesterol levels.

Couple addicted to the internet let their baby starve to death while raising a virtual daughter online

From BBC:

A South Korean couple who were addicted to the internet let their three-month-old baby starve to death while raising a virtual daughter online, police said.

An autopsy showed her death was caused by a long period of malnutrition.

The couple had become obsessed with nurturing a virtual girl called Anima in the popular role-playing game Prius Online.

Some psychiatrists still have doubts if Internet addiction exists but it looks pretty much for real in this video:

Erectile dysfunction is a strong predictor of death in men with cardiovascular disease

From CNN:

Men with cardiovascular disease and ED were twice as likely to die from all causes than men who did not have erectile dysfunction. And those with ED were 1.6 times more likely to suffer from a serious cardiovascular problem such as a heart attack or stroke.

Erectile dysfunction is something that regularly should be addressed in the medical history of patients; it might be a symptom of early atherosclerosis.

Men with ED who are going to a general practitioner or a urologist need to be referred for a cardiology workup to determine existing cardiovascular disease and proper treatment. ED is an early predictor of cardiovascular disease.

The Lancet: Commonest cause of maternal death is post-partum haemorrhage - one woman dies every 7 minutes

99% of all deaths in childbirth are in the least developed countries - 45 million women deliver without a skilled birth attendant every year, a situation in which the greatest number of maternal deaths occur.

The commonest single cause of maternal death is from post-partum haemorrhage, from which one woman dies every 7 minutes.
