Pakistan Temperatures Cross 52 C in Heatwave

Temperatures rose above 52 degrees Celsius (125.6 degrees Fahrenheit) in Pakistan’s southern province of Sindh, the highest reading of the summer and close to the country’s record high amid an ongoing heatwave, the met office said on Monday.

Extreme temperatures throughout Asia over the past month were made worse most likely as a result of human-driven climate change, a team of international scientists have said.

In Mohenjo Daro, a town in Sindh known for archaeological sites that date back to the Indus Valley Civilization built in 2500 BC, temperatures rose as high as 52.2 C (126 F) over the last 24 hours, a senior official of the Pakistan Meteorological Department, Shahid Abbas told Reuters.

The reading is the highest of the summer so far, and approached the town's and country's record highs of 53.5 C (128.3 F) and 54 C (129.2 F) respectively.

Mohenjo Daro is a small town that experiences extremely hot summers and mild winters, and low rainfall, but its limited markets, including bakeries, tea shops, mechanics, electronic repair shops, and fruit and vegetable sellers, are usually bustling with customers.

But with the current heatwave, shops are seeing almost no footfall.

"The customers are not coming to the restaurant because of extreme heat. I sit idle at the restaurant with these tables and chairs and without any customers," Wajid Ali, 32, who owns a tea stall in the town.

"I take baths several times a day which gives me a little relief. Also there is no power. The heat has made us very uneasy."

Close to Ali's shop is an electronic repairs shop run by Abdul Khaliq, 30, who was sat working with the shop's shutter half down to shield him from the sun. Khaliq also complained about the heat affecting business.

Local doctor Mushtaq Ahmed added that the locals have adjusted to living in the extreme weather conditions and prefer staying indoors or near water.

“Pakistan is the fifth most vulnerable country to the impact of climate change. We have witnessed above normal rains, floods,” Rubina Khursheed Alam, the prime minister’s coordinator on climate, said at a news conference on Friday adding that the government is running awareness campaigns due to the heatwaves.

The highest temperature recorded in Pakistan was in 2017 when temperatures rose to 54 C (129.2 F) in the city of Turbat, located in the Southwestern province of Balochistan. This was the second hottest in Asia and fourth highest in the world, said Sardar Sarfaraz, Chief Meteorologist at the Pakistan Meteorological Department

The heatwave will subside in Mohenjo Daro and surrounding areas, but another spell is expected to hit other areas in Sindh, including the capital, Karachi - Pakistan's largest city.



Blood Tests Allow 30-year Estimates of Women's Cardio Risks, New Study Says

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.”
