Scientists know that air air pollution could make it tough to breathe and will in the end trigger severe well being issues like most cancers, however a brand new examine exhibits that it may also have a destructive affect on teenagers’ blood strain.

Publicity to increased ranges of nitrogen dioxide was related to decrease blood strain in teenagers, in keeping with the examine, printed Wednesday within the journal PLOS One. Publicity to particulate matter 2.5, also referred to as particle air pollution, was related to increased blood strain.

The researchers say the affect is “appreciable.”

Different research have discovered a connection between blood strain modifications and air pollution, however a lot of that work focuses on adults. Some analysis has additionally discovered destructive associations with air pollution publicity and youthful kids, however little has centered on teenagers.

Typically, low blood strain could cause rapid issues like confusion, tiredness, blurred imaginative and prescient and dizziness. Hypertension in adolescence can result in a lifetime of well being issues together with a better danger of stroke or coronary heart assault. It’s a number one danger issue for untimely demise worldwide.

The examine didn’t take a look at whether or not the teenagers had signs or well being results from the change in blood strain.

The scientists noticed this affiliation between air pollution and blood strain in information from the Determinants of Adolescent Social Nicely-Being and Well being examine, which tracks the well being of a big and ethnically various group of kids in London over time.

The researchers took information from greater than 3,200 teenagers and in contrast their information to their exposures to air pollution based mostly on annual air pollution ranges the place they lived.

Nitrogen dioxide air pollution is mostly related to traffic-related combustion byproducts. Nitrogen might assist crops develop, however it will possibly impair an individual’s capability to breathe and will trigger injury to the human respiratory tract. On this examine, the nitrogen was regarded as coming predominantly from diesel visitors.

The particle air pollution within the examine is so tiny – 1/twentieth of a width of a human hair – that it will possibly journey previous the physique’s typical defenses. As an alternative of being carried out when an individual exhales, it will possibly get caught within the lungs or go into the bloodstream. The particles trigger irritation and irritation and will result in an entire host of well being issues.

Particle air pollution can come from forest fires, wooden stoves, energy crops and coal fires. It will probably additionally come from visitors and development websites.

On this examine, the hyperlink between air pollution publicity and modifications in blood strain was stronger in women than in boys. The researchers can’t decide why there’s a gender distinction, however they discovered that 30% of the feminine individuals bought the least quantity of train among the many group and famous that that may impact blood strain.

“It’s thus crucial that air air pollution is improved in London to maximise the well being advantages of bodily train in younger individuals,” the examine says.

Though the examine can also’t pinpoint why teenagers’ blood strain modified with air pollution publicity, others have discovered that publicity to air air pollution might have an effect on the central nervous system, inflicting irritation and injury to the physique’s cells. Moreover, publicity to particle air pollution can disrupt an individual’s circadian rhythms, which may have an effect on blood strain. Particle air pollution publicity may additionally cut back the kidneys’ capability to excrete sodium in the course of the day, resulting in a better nighttime blood strain stage, the examine says.

When it got here to nitrogen dioxide air pollution, the researchers had beforehand achieved a crossover examine that concerned the blood strain of 12 wholesome teen individuals who have been uncovered to nitrogen oxide from a home fuel cooker with lit burners. Their blood strain fell in contrast with individuals uncovered to solely room air.

Within the new examine, the associations between air pollution and blood strain have been constant. Physique measurement, socieoecomonic standing and ethnicity didn’t change the outcomes.

Nevertheless, it appears solely at teenagers in London, and solely 8% of them have been individuals of colour. These kids have been uncovered to increased ranges of air pollution than White kids, the examine discovered.

Ranges of air pollution in London are additionally effectively above what World Well being Group tips recommend is secure for people. Nevertheless, the identical could possibly be mentioned for many any space on the earth. In 2019, 99% of the world’s inhabitants lived in locations that didn’t meet WHO’s advisable air high quality ranges.

Earlier work has proven that air pollution can injury a teen’s well being and will put them at a better danger for persistent illnesses like coronary heart issues later in life. Research in adults discovered that publicity to air air pollution can have an effect on blood strain even inside hours of publicity.

Air pollution prompted 1 in 6 deaths worldwide in 2019 alone, one other examine discovered.

Some consultants recommend that one strategy to cut back a teen’s danger of pollution-related well being issues is to spend money on moveable air cleaners with HEPA filters which are extremely efficient at lowering indoor air air pollution. Nevertheless, the filters can’t take away the entire drawback, and consultants say communitywide options via public coverage are what’s wanted.

Dr. Panagis Galiatsatos, an assistant professor in pulmonary and demanding care medication at Johns Hopkins Drugs, mentioned analysis like that is vital to generate a speculation about what these pollution are doing to individuals. Galiatsatos, a volunteer medical spokesperson with the American Lung Affiliation, was not concerned with the brand new examine.

“Plenty of these air pollutions are likely to cluster in economically deprived neighborhoods, so it’s one of many huge causes we need to all the time preserve an in depth eye on this, because it disproportionately impacts sure populations greater than others,” he mentioned.

Blood strain is a crucial marker to trace for well being as a result of it’s a surrogate to grasp the extra complicated processes that is likely to be taking place within the physique.

“My huge takeaway is that these toxins clearly appear to have some physiological affect on the cardiovascular system, and any manipulation needs to be taken into the context of a priority,” Galiatsatos mentioned.

Research co-author Dr. Seeromanie Harding, a professor of social epidemiology at King’s School London, mentioned she hopes it would result in extra analysis on the subject.

“On condition that greater than 1 million beneath 18s dwell in [London] neighborhoods the place air air pollution is increased than the advisable well being requirements,” she mentioned in a information launch, “there’s an pressing want for extra of those research to realize an in-depth understanding of the threats and alternatives to younger individuals’s improvement.”

Goldman Sachs’ chief warns global investors are staying on the ‘sidelines’ in China

Goldman Sachs’ chief warns global investors are staying on the ‘sidelines’ in China

Goldman Sachs’ chief executive has warned that global investors are still “predominantly on the sidelines” over deploying capital in China because of weak consumer confidence and difficulties getting money out of the country.

David Solomon said investors “continue to be concerned” about cashing out of investments in the world’s second-largest economy.

“It’s been very difficult over the course of the last five years to get capital out,” he told an event on Tuesday organised by the Hong Kong Monetary Authority, the territory’s de facto central bank.

“I think you’ve got a combination of issues that have global investors predominantly on the sidelines with respect to capital deployment,” Solomon said.

He added that investors would like to see “an improvement in consumption” in China and “continued progress in the opening up of the capital markets”. 

Speaking on the same panel, Morgan Stanley chief executive Ted Pick said he agreed with Solomon. “Transparency is important and battling deflation takes time,” he said.

Deflationary pressures have increased in China, where the country’s leadership is trying to stabilise a property sector crisis and boost domestic consumption in order to meet its economic growth target of 5 per cent for the year.

Chinese stocks rallied in September after Beijing launched a stimulus package, including measures to boost the stock market. But the rally has cooled as authorities held off from making significant new fiscal spending announcements.

The CSI 300, China’s blue-chip index, on Tuesday closed down 11 per cent from a post-stimulus peak on October 8.

“The fiscal piece will take time, the real estate dynamic is going to take a number of quarters,” said Pick. “Clearly the name of the game here is to reignite consumer confidence and that’s something that takes a while to take hold, but we’re seeing some green shoots.”

The conference is a sign of HKMA’s sway over global financial institutions even as US-China relations fray. The annual event is attended by the biggest names on Wall Street, in part because the HKMA oversees hundreds of billions of dollars and is a valuable client and limited partner of many of the institutions.

Attendees included Apollo Global Management’s chief executive Marc Rowan, Blackstone president Jon Gray, and leading figures from buyout groups KKR, TPG, CVC and Carlyle.

Solomon and Pick were responding to a question from deputy HKMA chief Howard Lee about whether China’s stimulus package and “positive remarks” from Beijing officials, who stressed the importance of China opening up to the world, would make investors “feel more assured” about the country.

Earlier in the morning, China’s vice-premier He Lifeng delivered a speech in which he said mainland officials wanted to preserve Hong Kong’s status as an international financial centre while encouraging greater mutual market access between the city and the rest of mainland China.

The bank bosses spoke briefly about Donald Trump’s US election victory. Citi chief executive Jane Fraser said it had prompted a “big unlock” in demand for initial public offerings and mergers and acquisitions that had been “very gummed up” in recent years.

The prospect of reduced regulation “puts many CEOs in a good mood”, she said.

California governor delays clemency decision for Menendez brothers pending new DA review | CNN

California governor delays clemency decision for Menendez brothers pending new DA review | CNN



CNN
 — 

California Gov. Gavin Newsom will delay his decision on clemency for Lyle and Erik Menendez, who were convicted of murdering their parents in 1989, until the newly elected Los Angeles County district attorney completes his review of the case, Newsom’s office said Monday.

“The governor respects the role of the district attorney in ensuring justice is served and recognizes that voters have entrusted District Attorney-elect (Nathan) Hochman to carry out this responsibility,” Newsom’s office stated. “The governor will defer to the DA-elect’s review and analysis of the Menendez case prior to making any clemency decisions.”

Current District Attorney George Gascón, who has voiced strong support for the Menendez brothers’ clemency petition and submitted letters to the governor advocating for them, requested a judge in October to resentence the siblings, who are serving life without parole.

Gascón was recently defeated in his reelection bid by Hochman, a former federal prosecutor who campaigned on a tougher stance against crime. With Hochman set to take office in December, questions have arisen about the future of the resentencing effort and the clemency process.

Hochman stated that he is committed to thoroughly reviewing the Menendez case, including the confidential prison files, trial transcripts and extensive exhibits, as well as consulting with prosecutors, defense attorneys and family members of the victims.

“This is the same type of rigorous analysis I have done throughout my 34-year career in criminal justice as a prosecutor and defense counsel, and the same type of thorough review that I will give to all cases regardless of media attention,” he told CNN.

The brothers, family members and the public deserve a thorough review, Hochman said.

The renewed examination of the Menendez case comes more than 35 years after Jose and Kitty Menendez were shot dead in their Beverly Hills home. Their sons, then 21 and 18, were arrested less than a year later in 1990 and found guilty of first-degree murder in 1996.

During their two highly publicized trials, the brothers did not dispute the act of killing their parents but claimed self-defense, citing a lifetime of physical and sexual abuse by their father. The first trial, notable for being one of the earliest televised cases, ended in a mistrial due to a hung jury. In the subsequent trial, much of the evidence regarding the alleged abuse was deemed inadmissible, resulting in the brothers’ conviction and life sentences.

Attention to the case has surged following the September release of the Netflix series “Monsters: The Lyle and Erik Menendez Story.” Netflix recently launched a documentary on the case, featuring the brothers discussing the events that led to the tragic killings.

Hong Kong sentences 45 democracy activists to up to 10 years in prison

A Hong Kong court has sentenced 45 leading pro-democracy activists to up to 10 years in prison in a landmark security case as authorities stamp out dissent in the Chinese territory.

Legal scholar Benny Tai received 10 years in prison, the heaviest sentence. The court, in its ruling on Tuesday, said that Tai was a “principal offender” in organising an unofficial primary election in 2020.

The other defendants received sentences of between four and eight years. Joshua Wong, a former leading student protest organiser, was sentenced to more than four years in prison, while Gordon Ng, an Australian national, received more than seven years.

“One day in prison is too many,” said Chan Po-ying, wife of former lawmaker Leung Kwok-hung, 68, who was sentenced to 81 months.

The trial of the Hong Kong 47, as the case was known, was the largest national security trial in Hong Kong, which has been struggling to restore its reputation as an international financial centre in the wake of Beijing’s political crackdown and coronavirus pandemic restrictions.

“This case is unprecedented in Hong Kong’s history of democratic movement,” said Eric Lai, a research fellow at Georgetown University’s Center for Asian Law. “Hong Kong’s pro-democracy movement will suffer for many years due to the vacuum of leaders and outstanding activists.”

The defendants — who were arrested in sweeping dawn raids in January 2021 — represented some of the city’s most prominent pro-democracy politicians, activists, union officials, journalists, academics and student leaders.

Thirty-one, including Tai and Wong, had pleaded guilty in hopes of receiving reduced sentences, while 14 were convicted in May. Two were previously acquitted, though prosecutors have filed an appeal against one of the acquittals.

Most of the defendants have been in detention for more than three years after being denied bail. The charges carried a maximum penalty of life imprisonment.
