Hundreds of Philippine Schools Suspend Classes over Heat Danger

Hundreds of schools in the Philippines, including dozens in the capital Manila, suspended in-person classes on Tuesday due to dangerous levels of heat, education officials said.
The country's heat index measures what a temperature feels like, taking into account humidity.
The index was expected to reach the "danger" level of 42 degrees Celsius in Manila on Tuesday and 43C on Wednesday, with similar levels in a dozen other areas of the country, the state weather forecaster said.
The actual highest temperature forecast for the metropolis on Tuesday was 34C, reported AFP.
Primary and secondary schools in Quezon, the most populous part of the city, were ordered to shut while schools in other areas were given the option by local officials to shift to remote learning.
Some schools in Manila shortened class hours to avoid the hottest part of the day.
A heat index of 42-51C can cause heat cramps and heat exhaustion, with heat stroke "probable with continued exposure", the weather forecaster said in an advisory.
Heat cramps and heat exhaustion are also possible at 33-41C, according to the forecaster.
Local officials in several areas of the southern island of Mindanao also suspended in-person classes or shortened school hours over two weeks, regional education department spokeswoman Rea Halique told AFP.
The orders affected hundreds of schools in the provinces of Cotabato, South Cotabato and Sultan Kudarat, as well as the cities of Cotabato, General Santos and Koronadal, Halique said.
Cotabato city experienced the highest heat index in Mindanao, reaching 42C on Monday and Tuesday, the state forecaster reported.

Women’s heart disease risks and their need to start taking preventive medications should be evaluated when they are in their 30s rather than well after menopause as is now the practice, said researchers who published a study on Saturday.

Presenting the findings at the European Society of Cardiology annual meeting in London, they said the study showed for the first time that simple blood tests make it possible to estimate a woman’s risk of cardiovascular disease over the next three decades.

"This is good for patients first and foremost, but it is also important information for (manufacturers of) cholesterol lowering drugs, anti-inflammatory drugs, and lipoprotein(a)lowering drugs - the implications for therapy are broad," said study leader Dr. Paul Ridker of Brigham and Women’s Hospital in Boston, Reuters reported.

Current guidelines “suggest to physicians that women should generally not be considered for preventive therapies until their 60s and 70s. These new data... clearly demonstrate that our guidelines need to change,” Ridker said. “We must move beyond discussions of 5 or 10 year risk."

The 27,939 participants in the long-term Women’s Health Initiative study had blood tests between 1992 and 1995 for low density lipoprotein cholesterol (LDL-C or “bad cholesterol”), which are already a part of routine care.

They also had tests for high-sensitivity C-reactive protein (hsCRP) - a marker of blood vessel inflammation - and lipoprotein(a), a genetically determined type of fat.

Compared to risks in women with the lowest levels of each marker, risks for major cardiovascular events like heart attacks or strokes over the next 30 years were 36% higher in women with the highest levels of LDL-C, 70% higher in women with the highest levels of hsCRP, and 33% higher in those with the highest levels of lipoprotein(a).

Women in whom all three markers were in the highest range were 2.6 times more likely to have a major cardiovascular event and 3.7 times more likely to have a stroke over the next three decades, according to a report of the study in The New England Journal of Medicine published to coincide with the presentation at the meeting.

“The three biomarkers are fully independent of each other and tell us about different biologic issues each individual woman faces,” Ridker said.

“The therapies we might use in response to an elevation in each biomarker are markedly different, and physicians can now specifically target the individual person’s biologic problem.”

While drugs that lower LDL-C and hsCRP are widely available - including statins and certain pills for high blood pressure and heart failure - drugs that reduce lipoprotein(a) levels are still in development by companies, including Novartis , Amgen , Eli Lilly and London-based Silence Therapeutics.

In some cases, lifestyle changes such as exercising and quitting smoking can be helpful.

Most of the women in the study were white Americans, but the findings would likely “have even greater impact among Black and Hispanic women for whom there is even a higher prevalence of undetected and untreated inflammation,” Ridker said.

“This is a global problem,” he added. “We need universal screening for hsCRP ... and for lipoprotein(a), just as we already have universal screening for cholesterol.”
