Popping pills for six-pack abs? Think twice

August 8, 2013

Six-pack_absBangalore, Aug 8: Are you a gym rat aiming for a six-pack, and washing down spoonfuls of dietary supplements to tone up your body to impress your gal? It’s time you rethought all that. With no regulations governing the sale of muscle-enhancers, what with their easy availability over the counter, wary dietitians have cautioned users about their efficacity.

“These supplements are rich in protein and the need for protein differs from person to person. Factors like age, occupation, body type and weight play an important role,” says Dr V Malathi, Head of the Department of Nutrition, Manipal Hospital.

“The medical history of a person, too, is very crucial before one consumes these supplements,” she warned.

Fitness experts who train sportsmen, however, say gym instructors prescribing supplements is quite common. “There are two types of supplements - protein and general. Protein supplements are whey or creatine and the general ones are that claim to make you taller or stronger in weeks,” explains Deckline Leitao, performance enhancer at the Prakash Padukone Academy.

He says both can be harmful if taken without proper medical consultation.

“Protein supplements are effective input if you have the necessary amount of output, too. For a sportsperson or a person doing rigorous physical exercises, these supplements will be effective. But, if you are a youngster or a working professional, they are not helpful.

Most gym instructors are unqualified and don’t really understand how the body works.

They prescribe supplements to everybody, especially teenagers who want to quickly have a toned body.”

Dietitians warn people not to be carried away by the ‘magic’ formulas suggested by quack instructors. “Since supplements are easily available, not many consider going to a nutritionist or a dietitian. But you should always get a medical opinion, or consult a doctor. High intake of protein does not cause harms

like cholesterol increase, but it can cause hypoproteinemia or hyperuricemia which can later lead to grave problems,” says Dr Malathi.

When contacted, the Drugs Control Authority said there were no regulations for supplements. “We don’t have any rules or guidelines in place for these supplements,” said State Drug Controller Jaga Shetty.

Singapore, May 25: COVID-19 patients are no longer infectious after 11 days of getting sick even though some may still test positive, according to a new study by infectious disease experts in Singapore.

A positive test "does not equate to infectiousness or viable virus," a joint research paper by Singapore's National Centre for Infectious Diseases and the Academy of Medicine, Singapore said. The virus "could not be isolated or cultured after day 11 of illness."

The paper was based on a study of 73 patents in the city-state.

The latest findings may have implications on the country's patient discharge policy. The discharge criteria is currently based on negative test results rather than infectiousness.

Singapore's strategy on managing COVID-19 patients is guided by the latest local and international clinical scientific evidence, and the Ministry of Health will evaluate if the latest evidence can be incorporated into its patient clinical management plan, according to a report by the Straits Times.

So far, 13,882, or about 45% of the total 31,068 Covid-19 patients in Singapore have been discharged from hospitals and community facilities. Singapore reported 642 new Covid-19 cases as of noon on Saturday.

The government has been actively screening pre-school staff as it prepares to reopen pre-schools from June 2. On Friday, two pre-school employees tested positive for the novel coronavirus, bringing the total number of confirmed cases among pre-school staff to seven, according to the Ministry of Health.

Clinician-scientists have found that Irish patients admitted to hospital with severe coronavirus (COVID-19) infection are experiencing abnormal blood clotting that contributes to death in some patients.

The research team from the Royal College of Surgeons in Ireland found that abnormal blood clotting occurs in Irish patients with severe COVID-19 infection, causing micro-clots within the lungs.

According to the study, they also found that Irish patients with higher levels of blood clotting activity had a significantly worse prognosis and were more likely to require ICU admission.

"Our novel findings demonstrate that COVID-19 is associated with a unique type of blood clotting disorder that is primarily focussed within the lungs and which undoubtedly contributes to the high levels of mortality being seen in patients with COVID-19," said Professor James O'Donnell from St James's Hospital in Ireland.

In addition to pneumonia affecting the small air sacs within the lungs, the research team has also hundreds of small blood clots throughout the lungs.

This scenario is not seen with other types of lung infection and explains why blood oxygen levels fall dramatically in severe COVID-19 infection, the study, published in the British Journal of Haematology said.

"Understanding how these micro-clots are being formed within the lung is critical so that we can develop more effective treatments for our patients, particularly those in high-risk groups," O'Donnell said.

"Further studies will be required to investigate whether different blood-thinning treatments may have a role in selected high-risk patients in order to reduce the risk of clot formation," Professor O'Donnell added.

According to the study, emerging evidence also shows that the abnormal blood-clotting problem in COVID-19 results in a significantly increased risk of heart attacks and strokes.

As of Friday morning, the cases increased to 20,612 cases in Ireland, with 1,232 deaths so far, according to the Johns Hopkins University.

London, Jul 2: The World Health Organisation says smoking is linked to a higher risk of severe illness and death from the coronavirus in hospitalised patients, although it was unable to specify exactly how much greater those risks might be.

In a scientific brief published this week, the U.N. health agency reviewed 34 published studies on the association between smoking and Covid-19, including the probability of infection, hospitalisation, severity of disease and death.

WHO noted that smokers represent up to 18% of hospitalised coronavirus patients and that there appeared to be a significant link between whether or not patients smoked and the severity of disease they suffered, the type of hospital interventions required and patients' risk of dying.

In April, French researchers released a small study suggesting smokers were at less risk of catching Covid-19 and planned to test nicotine patches on patients and health workers — but their findings were questioned by many scientists at the time who cited the lack of definitive data.

WHO says "the available evidence suggests that smoking is associated with increased severity of disease and death in hospitalized Covid-19 patients. It recommends that smokers quit.
