Europe, Jan 11: Researchers have revealed the people who drink tea at least three times a week have healthy years of life and longer life expectancy.

The research was published in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).

Dr Xinyan Wang, who is the author of the study, said: "Habitual tea consumption is associated with lower risks of cardiovascular disease and all-cause death. The favourable health effects are the most robust for green tea and for long-term habitual tea drinkers."
The analysis that was conducted included about 100,902 participants of the China-PAR project2 with no history of heart attack, stroke, or cancer.

Participants were classified into two groups: Habitual tea drinkers and never or non-habitual tea drinkers and followed-up for a median of 7.3 years.

The analyses estimated that 50-year-old habitual tea drinkers would develop coronary heart disease and stroke 1.41 years later and live 1.26 years longer than those who never or seldom drank tea. Compared with never or non-habitual tea drinkers, the habitual tea consumers had a 20 per cent lower risk of incident heart disease and stroke, 22 per cent lower risk of fatal heart disease and stroke, and 15 per cent decreased risk of all-cause death.

The potential influence of changes in tea drinking behaviour was suspected in a subset of 14,081 participants with assessments at two-time points. The average duration between the two surveys was 8.2 years, and the median follow-up after the second survey was 5.3 years.

Habitual tea drinkers who maintained their habit in both surveys had a 39 per cent lower risk of incident heart disease and stroke, 56 per cent lower risk of fatal heart disease and stroke, and 29 per cent decreased risk of all-cause death compared to consistent never or non-habitual tea drinkers.

Senior author Dr Dongfeng Gu said: "The protective effects of tea were most pronounced among the consistent habitual tea drinking group. Mechanism studies have suggested that the main bioactive compounds in tea, namely polyphenols, are not stored in the body long-term. Thus, frequent tea intake over an extended period may be necessary for the cardioprotective effect."

In a subanalysis by type of tea, drinking green tea was linked with approximately 25 per cent lower risks for incident heart disease and stroke, fatal heart disease and stroke, and all-cause death. However, no significant associations were observed for black tea.
Dr Gu noted that a preference for green tea is unique to East Asia.

Two factors may be at play. First, green tea is a rich source of polyphenols which protect against cardiovascular disease and its risk factors including high blood pressure and dyslipidaemia. Black tea is fully fermented and during this process, polyphenols are oxidised into pigments and may lose their antioxidant effects. Second, black tea is often served with milk, which previous research has shown may counteract the favourable health effects of tea on vascular function.

Gender-specific analyses showed that the protective effects of habitual tea consumption were pronounced and robust across different outcomes for men, but only modest for women. Dr Wang said: "One reason might be that 48 per cent of men were habitual tea consumers compared to just 20 per cent of women. Secondly, women had a much lower incidence of, and mortality from, heart disease and stroke. These differences made it more likely to find statistically significant results among men."

She said: "The China-PAR project is ongoing, and with more person-years of follow-up among women the associations may become more pronounced."

In conclusion, the authors have found that randomised trials are required to validate the results and to illustrate nutritional guidelines and advice for lifestyle.

Oslo, Jan 17: Norwegian officials said 29 people had died in the country a short time after receiving their first dose of the Covid-19 vaccine. Of those deaths, at least 13 have been autopsied, with the results suggesting that common side effects may have contributed to severe reactions in frail, elderly people, according to the Norwegian Medicines Agency.

Norway said Covid-19 vaccines may be too risky for the very old and terminally ill, the most cautious statement yet from a European health authority as countries assess the real-world side effects of the first shots to gain approval.

“For those with the most severe frailty, even relatively mild vaccine side effects can have serious consequences,” the Norwegian Institute of Public Health said. “For those who have a very short remaining life span anyway, the benefit of the vaccine may be marginal or irrelevant.”

The recommendation does not mean younger, healthier people should avoid being vaccinated. But it’s an early indication of what to watch as countries begin to issue safety monitoring reports on the vaccines. Emer Cooke, the new head of the European Medicines Agency, has said tracking the safety of Covid vaccines, especially those relying on novel technologies such as messenger RNA, would be one of the biggest challenges once shots are rolled out widely.

Pfizer and BioNTech are working with the Norwegian regulator to investigate the deaths in Norway, Pfizer said in an e-mailed statement. The agency found that “the number of incidents so far is not alarming, and in line with expectations,” Pfizer said.

Allergic reactions have been uncommon so far. In the US, authorities reported 21 cases of severe allergic reactions from December 14-23 after administration of about 1.9 million initial doses of the vaccine developed by Pfizer Inc. and BioNTech SE. That’s an incidence of 11.1 cases per million doses, according to the Centers for Disease Control and Prevention.

Though both Covid-19 vaccines approved so far in Europe were tested in tens of thousands of people -- including volunteers in their late 80s and 90s -- the average trial participant was in his or her early 50s. The first people to be immunized in many places have been older than that as countries rush to inoculate nursing-home residents at high risk from the virus.

Norway has given at least one dose to about 33,000 people, focusing on those considered to be most at risk if they contract the virus, including the elderly. The Pfizer-BioNTech vaccine approved late last year has been used most broadly, with a similar shot from Moderna Inc. approved earlier this month also now being administered.

Of 29 cases of potential side effects investigated by Norwegian authorities, almost three-quarters were in people age 80 or older, the regulator said in a January 14 report.

In France, one frail patient died in a care home two hours after being vaccinated, but authorities said given the patient’s previous medical history there is no indication the death was linked to the vaccine. The French pharmaceutical safety agency on Thursday reported four cases of severe allergic reactions and two incidents of irregular heartbeat after vaccination.

The first Europe-wide safety report on the Pfizer-BioNTech vaccine will probably be published at the end of January, the regulator’s key medicines committee said Friday. Vaccine makers are required to submit data monthly.

In the UK, which has carried out more immunizations per capita than anywhere else in Europe, authorities will assess safety data and plan to publish details of suspected reactions “on a regular basis,” the Medicines and Healthcare Products Regulatory Agency said, without giving a date.

New Delhi, Jan 12: Amid the ongoing debate around the safety and efficacy aspects of Covid vaccines, the president of Indian Medical Association (IMA) has advised the public to not worry too much about it.

Speaking to IANS, Dr. J.A. Jayalal, president, IMA said, "We should not be too worried about the safety and efficacy of the vaccines since enough evidence is available to prove its credibility.

"The vaccines are never 100 per cent protective and efficacious at any time. It helps us to some extent in getting ahead of the disease but eventually, herd immunity will set in to control the viral spread. So let's not worry too much about the safety and efficacy part," he said.

"What we know from the trials is that the vaccines approved for inoculation in India are found safe and elicit an immune response. The technology of harnessing vaccines from inactivated viruses is a proven science. Our least expected efficacy criteria is 50 per cent while at the same time, other drugs we have been using for years are even below this benchmark of efficacy. We use influenza and vaccines against Tuberculosis but still people contract it," Jayalal explained.

"Even natural infection cannot determine the level of antibodies it would create in the body. Some may develop less antibodies, some may exhibit high titers of it while a few may never develop at all. Good thing is that the vaccines are producing antibodies and it's enough at this stage," he added.

Jayalal also said that the vaccine would work against the current and mutant strains of the coronavirus. Such claim was earlier made by Bharat Biotech for its Covid vaccine, Covaxin, which is approved for restricted emergency use in a clinical trial mode'. However, the firm is yet to present the data confirming its claim.

The apex association of modern medicine practitioners in the country has come out publicly endorsing the safety and efficacy of Covid-19 vaccines. In a statement issued on Monday, it said that the association stands with the scientists to endorse the safety and efficacy of both Covaxin and Covishield for public awareness and to counter myths on vaccine percolating in social media.

The IMA has also appealed to its its 3.5 lakh members in 1,800 local branches to actively take part in the mission of Covid vaccination programme rolled out by the Government of India. "Come out to get vaccinated first to show to the world that these vaccines are safe and efficacious," it had said.

Despite the efficacy of both the vaccines still unknown, the IMA has endorsed the vaccines. When asked about it, Jayalal said the association had a detailed discussion on such aspects with the government agencies. "After analyzing all the scientific data, we have decided to come out firmly in support of the vaccines," he added.

India's drug regulator has approved two Covid vaccine candidates -- Covishield by Serum Institute of India and Covaxin by Bharat Biotech -- for the massive inoculation drive against the Covid-19.

The immunization drive will start from January 16. The vaccines have already reached many of the primary hubs to be distributed further before the roll-out.

Till now, a total 1,51,327 people have succumbed to the deadly disease while it has infected 1,04,79,179 people in the country.

UK Coronavirus Strain Detected in At Least 60 Countries: WHO

Geneva, Jan 20: The UK coronavirus strain has been detected in at least 60 countries, the World Health Organization said Wednesday, 10 more than a week ago.

With the global death toll now well past two million, and new variants of the virus causing deep concern, countries across the world are grappling with how to slow infections until vaccines become widely available.

The South African strain, which like the UK one is believed to be more infectious, has now been reported in 23 countries and territories, the WHO also announced in its weekly update.

It added that the number of new deaths climbed to a record high of 93,000 over the previous seven days, with 4.7 million new cases reported over the same period.

The arrival of mass vaccination campaigns in the US and Europe had brought hope that the end of the pandemic was in sight; the European Union said Tuesday it was aiming to inoculate 70 percent of its adult population before the end of August.

But many EU countries -- and other nations including India and Russia -- have struggled to get their inoculation programmes off the ground.

The United States remains home to the world's worst outbreak in overall numbers, and US President-elect Joe Biden made clear he would be taking no chances following his inauguration on Wednesday.

Recent days have also seen a renewed focus on the initial outbreak a year ago, with China defending its handling of the virus on Tuesday after independent experts criticised the speed of its response.
