Should screening for dengue be mandatory before blood transfusion?

I recently came across a story in The Muscat Daily (Jan. 23, 2019) which said "the Ministry of Health (MoH) and the Department of Blood Banks Services in Oman have announced on their Twitter accounts that "those affected by dengue virus will not be allowed to donate blood for six months". Dengue cases are being reported in the country. The latest figures by the Ministry of Health revealed that until January 22, there were 52 recorded cases of dengue fever. In a statement, MoH said, “As a precautionary measure to prevent the spread of the infection, residents and citizens of the dengue-affected areas will also not be allowed to donate blood for 28 days."  According to the Ministry, this is being put in place to help "prevent others from contracting the disease".

Travel is a risk factor for spread of any infectious disease. With increasing travel, there is a chance of the disease appearing in another part of the country or the globe, where it did not occur previously. Consequently, the prevalence of dengue has increased several-folds across the world...read more

A round-up of happenings in medicine this week

Alcohol and the AF link: India is going through a new epidemic of atrial fibrillation (AF), which is linked to acute attacks of paralysis. Now a study published in the journal Heart Rhythm has shown that regular alcohol intake at moderate levels (8-21 drinks per week) is associated with electrical and structural changes in atrial myocardium.    

Moderate alcohol consumption is an independent predictor of the atrial remodeling, characterized by significantly reduced atrial voltage and conduction velocities and increased atrial dimensions. The same was not found for mild alcohol intake levels, defined as two to seven drinks per week....read more

Cigarette filters are the no.1 plastic pollutant

Plastic straws and bags have received widespread attention as pollutants. But another, even bigger, plastic problem has been slipping under the radar --cigarette filters. Cigarette butts containing plastic filters are the most littered item in the world.
"Many smokers assume the filters are made of a biodegradable material," says Elizabeth Smith, who works on tobacco control policy at the University of California San Francisco. In fact, filters are made of cellulose acetate -- a type of plastic that can take up to a decade to decompose... read more

A high-fibre diet is the gateway to preventing non-communicable diseases (NCDs)
At least 50% of the diet should be composed of fruits and vegetables rich in fibre
New Delhi, 26 January 2019: According to ‘convincing evidence” from a study commissioned by the World Health Organisation, consuming fibre and whole grains can reduce health risks from non-communicable diseases (NCDs) such as heart disease. The paper published in The Lancet indicates that eating fibre-rich foods reduces the incidence of coronary heart disease, stroke, type 2 diabetes and colorectal cancer by 16% to 24%. A higher fibre intake is also associated with lower bodyweight, systolic blood pressure and total cholesterol when compared with lower intake.

The recommended daily allowance, or RDA, of the ICMR for fibre is 25g/day. A healthy diet is one in which about half is made up fruits and vegetables (45% to 50%) and a fourth is cereal and millets (rice/wheat/millets, etc). A person should get 55% to 60% of energy from carbohydrates, 25% to 30% energy from fats and oils (less than 10% energy from saturated fats and almost nil from trans fats), and 10% to 15% energy from protein diet.
