Kids with asthma often leave doctor’s office with unanswered questions

Adolescents with asthma do not always speak up during doctor visits and often leave with questions, a study suggests. 

About a third of teens with asthma do ask questions of doctors, but parents typically do most of the talking, the study authors found. 

“As teens grow up and become more independent, it becomes more and more important that they can manage their asthma on their own, without relying on their parents,” coauthor Scott Davis of the University of North Carolina at Chapel Hill told Reuters Health by e-mail. “If we can make teens more confident in asking their doctors the questions they have, they may be more likely to learn the skills they need to control their asthma.” 

Writing in the Journal of Allergy and Clinical Immunology: In Practice, Davis and colleagues describe what happened when they gave 185 asthmatic adolescents a one-page list of 22 questions about asthma medications and asthma triggers, before the youngsters doctors’ appointments. 

Previous studies have shown that physician-patient interactions are improved when patients have access to a “question prompt list”, which allows them to check the questions they want to ask during a visit and write in their own questions. 

On average, teens in the current study checked about four questions. About 11 per cent wrote in one or two questions. 

The most frequently checked question was “How severe is my asthma?” which was checked by about half of the teens. About a third of teens who checked questions asked, “What causes my asthma?” and “How can I make my asthma better?” The most frequently checked medication questions were, “How long do I hold my breath after I inhale my medicine?” and, “Should I use my asthma medicine before I play or exercise?” 

Only about a third of kids who checked at least one question actually asked at least one question during their appointment. 

The question most often asked after being checked on the list was, “What causes my asthma?” However, only 10 per cent of teens who checked “How do I prevent breathing problems?” actually asked the question. 

Of the asthma medication questions, 40 per cent of teens who checked “Should I always carry my asthma medicine with me?” and “Is it okay to take my asthma medicine with my other medicines?” raised those questions with their doctor. At the same time, nobody who checked important questions such as “Can you show me how to use my medicine?” and “Can I show or tell you how I use my medicine, so you can tell me if I am doing it right?” actually asked their doctor. 

“Parents have a role to play in empowering their teens to speak up during medical visits and ask questions,” Davis said. “Teens with asthma especially need to know how to use their inhaler correctly but are often reluctant to ask their doctor to show them.” 

 “As a clinician, it becomes second nature to direct conversation to the adult caregiver, especially if there is a longstanding relationship between provider and caregiver,” said Dr Tamara Perry of the University of Arkansas for Medical Sciences in Little Rock. Perry, who was not involved with this study, has researched how teens may use smartphone apps for self-management of their asthma. 

“As children grow up, clinicians and caregivers have to be intentional and remain mindful that adolescents don’t always feel empowered to ask questions,” she told Reuters Health by e-mail. “It’s up to us to help them engage in their care by bringing them into the conversation.” 

Weight-loss surgery can bring lasting improvement in sexual function

Weight-loss surgery has more benefits than simply slimming a patient down since it may also result in lasting improvements to sexual functioning, a new study suggests. 

In the multicentre study that included more than 2,000 men and women who had problems with sexual functioning before surgery, researchers found that more than half reported improvements in their sex lives within a year of the surgery. The improved functioning continued for most of these patients through five years of follow-up, the study team reports in “JAMA Surgery”. 

“Satisfaction with sexual life is improved by one year after bariatric surgery, and this improvement is maintained in both men and women by five years post-surgery,” said the study’s lead author, Kristine Steffen of the School of Pharmacy at North Dakota State University in Fargo. 

At the start of the study, the 1,607 women and 429 men included in the analysis had filled out questionnaires that asked about sexual function and satisfaction, and all had reported problems. The questions included whether, in the past month, the individual had “felt sexual desire or interest, that is, desire or interest to engage in any activity that is arousing to you, alone or with a partner”, as well as how often they had participated in sexual activity, how much their physical health had limited sexual activity and how satisfied overall they were with their sex lives. 

The questions were asked again one year and five years post-surgery. Prior to surgery 1,015 of 1,456 (69.7 per cent) women and 304 of 409 (74.3 per cent) men said they were not satisfied with their sex lives. Among the participants who were dissatisfied, 56 per cent of women and 49.2 per cent of men experienced meaningful improvements at one year. 

Specifically, men were 1.57 times more likely than they were before the surgery to experience improvements in the frequency of feeling sexual desire, 1.53 times more likely to experience improvements in the frequency of sexual activity, 3.97 times more likely to experience fewer physical limitations to having sex and 2.37 times more likely to experience improvements in satisfaction with their sex lives. 

Women were 1.5 times more likely a year post-surgery than before their operations to experience improvements in the frequency of feeling sexual desire, 1.53 times more likely to experience improvements in the frequency of sexual activity, 3.7 times more likely to experience fewer physical limitations to having sex and 2.11 times more likely to experience improvements in satisfaction with their sex lives. 

Many of these improvements lasted for a full five years. For those who had improvements at year one in physical limitations, for instance, three-quarters of the women and more than two-thirds of the men continued to report improvement at year five. 

“There were significantly fewer women who had improvements in frequency of desire, frequency of activity and degree to which physical health limits sexual activity at year five post-surgery compared with year one post-surgery,” Steffen noted in an email. 

“In women, early improvement in satisfaction with sexual life was maintained by year five. In men dissatisfied before surgery, early improvements were maintained by year five in all domains except the degree to which physical health limits sexual activity.” 

“[The new study] highlights the importance of looking beyond what we traditionally look at with bariatric surgery”, said Kimberley Steele of Johns Hopkins Medicine in Baltimore. “Traditionally we’re looking at weight-loss outcomes and outcomes related to weight loss, such as diabetes, cholesterol, hypertension and sleep apnoea.” 

Steele, who was not involved in the study, said she hopes it will raise awareness about “something that is not talked about that often: sexual function”. Almost 70 per cent of women and 74.3 per cent of men listed that as a problem for them preoperatively, she noted. 

“This was a nice way through validated surgery and a large cohort to show how weight loss through bariatric surgery improves sexual function and therefore quality of life,” Steele said. “More women than men seek bariatric surgery. By raising awareness that weight loss improved sexual dysfunction and therefore also quality of life, maybe this will encourage more men to consider the option of bariatric surgery.”

A dose of alternate history and science fiction

By - Feb 26,2019 - Last updated at Feb 26,2019

I am sure that all of us have a healthy love for watching good TV shows. There is hardly a gathering where my friends and I have not talked about the latest season of a series we had binge- watched the week before, and impatiently wait for the months to pass so we can watch the next instalment. 

But I have noticed that there is one particular show that has escaped the attention of everyone I have spoken to. At first I thought it was weird that people were not talking about, in my opinion, one of the most amazing series — until I realised they had no idea it existed. The show I’m talking about is none other than “The Man in the High Castle”.

Created by television writer and executive producer Frank Spotnitz for Amazon Prime, and loosely based on the legendary novel of the same name by the famed author Philip K. Dick, “The Man in the High Castle” takes you through the biggest what-if scenario in literary history.  

The story takes place in an alternate 1960s North America where Nazi Germany and the Empire of Japan have won World War II, and now have divided what used to be the United States, and the rest of the world for that matter, between them. 

We follow characters like Juliana Crane, played by Alexa Davalos (“The Chronicles of Riddick”, “Clash of the Titans”), who discovers a mysterious film that has the potential of toppling the worlds tyrannical regimes, or Joe Blake, played by Luke Kleintank (“Pretty Little Liars”, “Bones”), a Nazi double agent working for US army officer turned senior SS officer John Smith, played by Rufus Sewell (“Gods of Egypt”, “Abraham Lincoln: Vampire Hunter”).

“The Man in the High Castle” is a perfect blend of action and drama that will have you sitting at the edge of your seat, making you addicted within the first few episodes. And if you think all that was not enough, it also brings in a tasteful amount of science fiction by way of technological advances made by the Nazis and the possibility of travelling to alternate universes through psychic or mechanical means. 

Another important aspect of the show is its clear portrayal of the fact that the world is not just black and white, but has a large area of grey that most people live in and it is the choices we make that determine our destiny. 

It shows the human side to the characters as the episodes progress by making us witness the trials and tribulations of our protagonists, and the spiritual and moral conflicts within the members of the reigning regimes that make us, dare I say, sympathise with the characters. 

With the third season released in the autumn of last year and the fourth season already in production, it has already won multiple awards, including two Primetime Emmy Awards, and was nominated for dozens of other awards. It is a perfect new show to binge- watch that will leave you wanting more. The depth of the characters and the immense talent of the actors and actresses will amaze you.

You will see the enormous hard work put into bringing the world of “The Man in the High Castle” to life in every episode, whether it is Nazi propaganda and symbolism dominantly displayed all over an alternate occupied New York, or a Japanese imperial armada sailing through San Francisco Harbour. 

One thing is clear about this gem of a show, you will not be sorry to experience its amazing overall quality. So I suggest you start watching now because the journey the characters are embarking on is not over, the secrets of “The Man in the High Castle” have not yet been fully revealed and the resistance has only just begun.

‘How to Train Your Dragon’ soars to top of box office

LOS ANGELES — Universal’s “How to Train Your Dragon: The Hidden World” debuted atop the North American box office, taking in $55 million, industry tracker Exhibitor Relations said on Monday.

The animated film ended the weekend ahead of the two earlier instalments in the “Train Your Dragon” series — neither of which hit $50 million — making it the top domestic opener of the year, according to Variety magazine.

Voiced by Jay Baruchel, America Ferrera, Cate Blanchett and F. Murray Abraham, the new instalment tells the story of young Hiccup and his dragon Toothless, as a surging dragon population forces them to seek a “Hidden World” supposed to be a utopia for the winged creatures. 

Last weekend’s box office leader, Fox’s “Alita: Battle Angel”, clung to the second spot, but only after dropping sharply to take in just $12.3 million. The sci-fi fantasy stars Rosa Salazar as a cyborg who has lost her memory.

In third was “The Lego Movie 2: The Second Part” from Warner Bros., which took $9.7 million. The animated story of love and chaos in an apocalyptic toyland features the voices of Chris Pratt, Elizabeth Banks and Will Arnett.

MGM’s “Fighting With My Family” placed fourth at $7.8 million. The semi-serious wrestling comedy stars Florence Pugh as a young woman struggling, along with her family, to make it big in the pro-wrestling world. Dwayne Johnson as “The Rock” encourages her on her quest.

Fifth place went to “Isn’t It Romantic” from Warner Bros., which took $7.1 million. It stars Rebel Wilson as a rom-com hating New Yorker who, after suffering a blow to the head, finds herself living in her own romantic comedy.

Rounding out the weekend’s top 10 were “What Men Want” ($5.2 million), “Happy Death Day 2U” ($4.9 million), “Cold Pursuit” ($3.2 million), “The Upside” ($3.2 million) and “Run the Race” ($2.2 million).

Samsung announces folding phone with 5G

By Stephen Nellis and Paul Sandle

SAN FRANCISCO/LONDON — Samsung Electronics Co. Ltd. on Wednesday unveiled a nearly $2,000 folding smartphone in a bid to top the technology of Apple Inc. and Chinese rivals and reignite consumer interest amid slumping sales. 

The Galaxy Fold will go on sale on April 26 and take advantage of new and faster 5G mobile networks. The device looks similar to a conventional smartphone, but then opens like a book to reveal a display the size of a small tablet at 7.3 inches. 

The device “answers sceptics who said that everything that could be done has been done”, DJ Koh, chief executive of Samsung Electronics, said at an event in San Francisco. “We are here to prove them wrong.” 

Samsung remains the world’s largest smartphone maker with nearly a fifth of global unit sales but underperformed a slumping market last year. Chinese rival Huawei Technologies Co. Ltd. — whose Mate series of phones also command premium prices — gained market share. Other Chinese makers like Xiaomi Corp. have also been increasing prices, leaving Samsung to defend its turf against upstart rivals in addition to its longtime foe Apple. 

With the foldable phone, Samsung is going on the offense on two fronts in the smartphone race: it is offering an eye-catching new feature with the big, bending screen and the first 5G connection in a premium phone, a feature analysts do not expect Apple to match until 2020. 

Samsung is also making improvements to its flagship Galaxy S devices and plans to offer a 4G version of its folding phone. 

It also challenges the notion of what a phone can cost, debuting at nearly twice the price of current top-of-the-line models from Apple and Samsung itself. 

Patrick Moorhead, founder of Moor Insights & Strategy, said the new folding device could help Samsung stay at the top and lure consumers to upgrade devices that have looked largely the same over the past five years. 

“Samsung and Apple go back and forth” to lead the premium smartphone market, Moorhead said. “I think this is Samsung’s chance to take back the innovation crown.” 

And even though the $1,980 starting price is steep, some dedicated Samsung fans said they would pay it. Navneet Kumar Singh, a Samsung enthusiast from India who travelled to San Francisco to watch the launch, is ready to place his order. 

“The prices of the flagship models have been a little aggressive in India,” he said, “But in the end, if you invest the money you’re getting a different experience.” 

Samsung also introduced several accessories to compete against Apple, including a pair of wireless headphones called Galaxy Buds. The headphones include wireless charging, a feature that Apple has promised to put into is competing AirPods but has not yet released. 

Samsung also said that its new Galaxy phones will be able to wirelessly charge its headphones and new smartwatches by setting the accessories on the back of the phone. 

 

10 times faster 

 

Along with the folding phone, Samsung also added new cameras and a 5G version to its Galaxy series of phones. 

Verizon Communications Inc. will be the first carrier to offer service for Samsung’s 5G phones. The networks are expected to be 10 times faster than current ones, improving viewing of live news and sports events. 

 

Folding phones? Makers pray you’ll want one

 

With the 5G versions of its flagships, the Korean electronics maker looks to have beaten Chinese rivals in the 5G race, although the device will operate only on the small number of networks launching later this year. Apple is not expected to release a 5G smartphone until late 2020. 

The new networks are not available in many places yet but will roll out this year and next. Consumers who want to hold on to their phones for several years before upgrading may be tempted to buy a 5G phone now so that it will be able to take advantage of those networks later, said Bob O’Donnell of TECHnalysis Research. That could sway some Apple buyers over to Samsung and other Android makers with 5G devices. 

“People are going to be thinking about, am going to be able to use this a year from now? Two years from now? Three years?” he said. 

Rival smartphone makers are expected to announce 5G models at next week’s Mobile World Congress, the industry’s top annual event, in Spain. Samsung said its 5G handset would be available in the early summer. 

The Galaxy 10 series needs to appeal to consumers who are reluctant to upgrade for only incremental technological improvements in performance. 

All of the Galaxy series of rigid phones except the 5G will be available from March 8, with the S10+ priced from $1,000, the S10 priced from $900 and the smaller S10e from $750. 

The mainline S10 compares with $999 for Apple’s iPhone XS and $858 for Huawei’s premium Mate 20 Pro. 

Volkswagen Touareg 3.0 TFSI: moving on up

By - Feb 25,2019 - Last updated at Feb 25,2019

A perfectly competent, capable all-rounder, and more accessible up-market offering in the then newly burgeoning SUV market when first introduced in 2002, the Volkswagen Touareg might not have been a particularly inspired or charismatic of vehicles in its first two generations. 

Now, however, the third generation Touareg may in passing seem a subtle evolution, but at closer examination it becomes evident that it has been virtually transformed. A bona fide premium SUV competing with the best the segment has to offer, the new Touareg also proved to be an unexpectedly rewarding drive with improved comfort and technology, and newfound agility and urge.

More upmarket and better driving than the vehicle it replaces, the new Touareg launched globally late last year and is already available in several Middle East markets. Not the first Touareg sharing architecture with more exotic and up-market cousins, Volkswagen’s latest large SUV, however, now features more of the technology, refinement and driving dynamics. Using the same Volkswagen group MLBevo platform as the Lamborghini Urus, Bentley Bentayga, Porsche Cayenne and Audi Q8 and Q7 models, the new Touareg uses more aluminium intensive construction. Consequently, its body is 106kg lighter despite it being slightly larger and considerably better equipped car than its predecessor.

 

Sharp and responsive

 

Distinctly classier in design, the new Touareg ditches the outgoing model’s rounded body in favour of tauter, more chiseled surfacing with sharper and more deliberate lines, ridges and edges. Its chrome-heavy fascia seamlessly incorporates browed headlight clusters and LED elements with a vast multi-slatted grille. Featuring better flowing lines, detailing and lines, the new Toureg’s roofline is faster and more rakish, while side views feature better defined wheel-arches, rocker panels and surfacing. At the rear, its design is better resolved and design elements more tightly packaged, and include slimmer, sharper rear lights, more pronounced tailgate-top spoiler and dual integrated chrome-tipped exhaust ports.

Launched in most markets with turbo-diesel power and petrol on the way, the Touareg, however, arrives in Middle East markets with 4-cylinder and V6 petrol engines from the outset. Driven in top Highline specification with Volkswagen’s now familiar direct injection 3-litre turbocharged V6 TFSI petrol engine, the Touareg develops 335BHP and 332lb/ft torque. Though unspecified, maximum torque is on tap at what is evidently a broad and low range and power plateaus with relatively low-revving accessibility. Responsive and almost imperceptible turbo lag from idling, the Touareg’s delivery features fulsome mid-range delivery and a smooth, refined and almost elastically urgent climb to redline.

 

Swift and smooth

 

Convincingly athletic and consistently responsive, the Touareg’s digs deep to a develop a welling mid-range torque that gives way to top-end power, and makes short work of overtaking manoeuvres and is swift pouncing out of corners. Estimated to complete the 0-100km/h sprint in just 5.9-seconds and to be capable of 250km/h, the Touareg’s slippery 0.32 aerodynamic drag and torque rich engine make it a willing and confident high way drive. Driving all four wheels through a smooth and swift shifting 8-speed automatic gearbox with a broad ratio spread for best performance, response, versatility, refinement and efficiency, the Touareg also features different driving mode profiles.

With its engine positioned longitudinally and just ahead of front axles for excellent front wheel traction and power delivered to all four wheels with the ability to redistribute power back and forth at up to 70 per cent to the front or 80 per cent rearwards as the situation dictates, the Touareg feels ever sure-footed. With excellent road-holding on tarmac, the Touareg features both different driving mode that adapt different systems for different situations on-road, as well as off-road. An optional Off-road Package allows for yet more off-road modes specifically tailored for sand, gravel and individual tailored characteristics. Furthermore, optional air suspension allows for increase ride height and 550mm water fording.

 

Nimble and sure-footed

 

Smooth, stable and supple at speed or whether cruising in town despite huge 20-inch alloy wheels and low profile 285/45R20 tyres — as driven on smooth Dubai roads — the Touareg’s air suspension offers a refined and comfortable ride that helps isolate one from harshness. That said, the Touareg surprisingly never felt disconnected or vague, and for a big SUV, felt surprisingly agile, despite some body lean through corners. If anything, the Touareg felt alive and tautly elastic through corners, with electronically controlled anti-roll bars tightening up to tidy up body control and four-wheel-drive reallocating power and clawing back traction from a rear shift, just as one reapplies power and blasts off onto the next corner.

More nimble its height and estimated 2-tonne weight suggest, the Touareg benefits from quick, well-damped, light and direct steering and tidy turn-in, and good brakes. Offered with optional four-wheel-steering, the Touareg is more agile and manoeuvrable than anticipated. With rear wheels turning opposite to the front at low speeds and its wheelbase effectively shortened, the Touareg can make a 180° in just 11.19-metres and deftly manoeuvre through twists and turns. Meanwhile at speed the rear wheels turn in the same direction for quick and sure-footed cornering like it is glued to the road, and for stable lane changes at speed.

 

Classy comfort

 

A high tech SUV packed with standard and optional convenience, comfort, infotainment, safety and driver assistance systems including massaging front seats, night vision thermal cameras, partly automated steering and lane departure Traffic Jam Assist system, heads-up display, and interactive LED headlights, the new Touareg’s electro-mechanical anti-roll bars are meanwhile powered by a 48v battery system, which would also theoretically allow for numerous other high tech systems as used by the Audi A8. Inside, the Touareg is the most digital Volkswagen to date and features a huge high definition and user-friendly 15-inch infotainment screen and 12-inch configurable digital instrument panel.

Comfortable, classy and uncluttered inside, the new Touareg feels and looks like a considerably more premium SUV with a cocooning yet spacious and highly adjustable driving position, and airy ambiance created by its large panoramic sunroof. Using good quality materials, leathers and plenty of soft textures, the Touareg feels upmarket and sophisticated without being gaudy, overstated or pretentious. Seating five in comfort, it can generously accommodate 810-litres of luggage, which expands to 1800-litres with the rear seats folded down.

Tarragon treasure: a medical miracle

By Sheela Sheth

Food Expert

 

This bitter sweet plant, also known as the dragon wart and tarkhum in Arabic, has an aromatic flavour similar to anise. A perennial herb in the sunflower family, it is native to Europe, Asia, India (my home country) and parts of northern Mexico. In Ayurveda (Indian herbal medicine), tarragon is known to have a strong cultural and historical attachment due its rich medicinal property. 

 

Antioxidant property

 

Some indigenous varieties of tarragon are known to have antioxidant properties that fight free radicals (free radicals cause damage to the body’s cells, leading to premature ageing and serious health problems). Tarragon oil works wonders in stopping the damage done by free radicals. It is widely used as a painkiller for toothache as it has the ability to numb the pain.

 

Medical miracle

 

Several studies have shown that tarragon appears to have chemicals which work as an appetite stimulant. It has been long used as a digestive tonic because it aids in the production of bile by the liver. It not only improves digestion but also relieves stomach upsets, irritable bowels and dyspepsia. Tarragon leaves also work as a mild sedative to help relieve anxiety and stress and the oil is widely used in dentistry to numb the nerves. It has also been shown to support cardiovascular health and also assists in keeping blood platelets, clotting agents in the blood, in order. It is also used for building muscle mass and weight control.

 

Cosmetic infusion

 

Tarragon is widely used to infuse aromatic oils, soaps, shampoos and certain moisturising skin lotions and creams to add aroma for treatment. Tarragon oil can improve hair lustre and reduce hair frizz. Steaming with a few leaves serves as a skin cleanser and its antioxidants help as an astringent. 

Culinary contribution

 

It is reminiscent of fennel and anise as it is liquorice in taste. The rich and pleasant aroma of tarragon leaves gives a delicate flavour to salads and soups. It is popularly used to flavour vinegar like dill or olive oil for salad dressing. It is often combined with capers and also used for flavouring sauces, especially in French and German cuisine.

 

Bring out the tarragon!

 

Pick some fresh greens and toss a tarragon dressing infused in olive oil, vinegar or lemon, honey, sun dried tomatoes and bell peppers. 

Be sure to consult your doctor before trying any herbal products.

Chemicals in e-cigarette flavours could harm respiratory tract

By - Feb 23,2019 - Last updated at Feb 23,2019

Two chemicals commonly used as e-cigarette flavours might harm users’ airway passages, a small experiment suggests. 

The results point to the need to further study how the highly popular cigarette alternatives affect human bodies, researchers say. 

In test tube experiments, the researchers exposed cells from the lining of human airways to two flavouring compounds: diacetyl — a chemical with a butter-like smell — and its “chemical cousin” 2,3-pentanedione. 

In the body, these so-called bronchial epithelial cells work with mucus to clear inhaled germs and particles. 

Researchers found that both chemicals induced hundreds of genetic changes in the cells. The chemicals also impaired the ability of the cells to function properly. 

“These flavouring chemicals are what we call ‘Generally Regarded As Safe’ chemicals. That designation, though, only refers to the ingestion pathway,” said study coauthor Joseph Allen, from the Harvard T.H. Chan School of Public Health in Boston. 

“They are food grade flavouring chemicals. They have not been tested for inhalation safety. And what we do know about users who inhale these flavouring chemicals is that they can cause severe lung disease,” Allen told Reuters Health by phone. 

In food, diacetyl is generally considered safe by experts. But older research going back a decade describes how workers at popcorn factory developed a serious respiratory condition called bronchiolitis obliterans, or “popcorn lung”, after inhaling the butter-flavoured compound. 

“It’s a good study and it’s a beginning,” said Irfan Rahman, a professor of Environmental Medicine at the University of Rochester Medical Centre in New York, who was not associated with the study. 

 “The flavour is causing some changes in the genes, which is a really key point in human lung epithelial cells,” said Rahman, who studies the effects of cigarette smoke on lung inflammation. 

“Lungs are not made for flavours to inhale. Our body is not yet ready,” Rahman said. 

Test tube experiments may not reflect real human exposure to e-cigarette, the researchers acknowledge. 

Also, they point out, they chose these two flavour chemicals to study based on preliminary investigations conducted in 2016. Today, e-cig manufacturers may have changed formulations. 

Indeed, Juul Labs Inc., a popular maker of e-cigarette devices, states on its website that it does not add either of these chemicals to its manufacturing process and lists other ingredients such as natural oils, extracts and flavours as its ingredients. 

“Some of the newer e-cigarette companies like Juul are starting to advertise that their products do not contain [these chemicals],” Allen said. 

“What is important to ask is: What flavours are they using?” he added 

E-cigarette and “vape” makers have come under fire from health regulators and governments as youth e-cigarette use increases, and worries arise about a burgeoning young population of e-cigarette users who may move on to smoking cigarettes. 

“Because of the associations of diacetyl inhalation exposure and severe respiratory diseases and increasing popularity of e-cig use among people, further mechanistic studies are warranted to evaluate the effects of diacetyl and related flavouring compounds in e-cig on airway epithelium,” the researchers note in their study published in “Scientific Reports”. 

Rarer than a Sumatran rhino: a woman composer

By - Feb 21,2019 - Last updated at Feb 21,2019

French music composer Camille Pepin poses in her studio, in Paris, on February 11 (AFP photo)

PARIS — Camille Pepin is part of a very rare breed. She is a female composer.

Women have conquered space and risen in the military ranks, but some professions remain resolutely and bewilderingly masculine.

When Pepin turned up for her first day at the Paris Conservatoire — as usual the only woman in a class of men — an official told her that her name was not on the list. 

But when she insisted that she was and that he look again, he cried, “Ah, you’re a woman!” 

Camille is also a man’s name in France.

“I would never have thought,” he apologised. “There are so many men...”

With so few female composers in the classical music repertoire, it was an easy mistake to make.

Pepin has never let everyday sexism get her down though, laughing it off like water off a duck’s back.

“One male composer told me I was getting commissions because I was a woman and not too bad looking,” said the 28-year-old, whose first album, “Chamber Music”, is released later this month.

After a concert of one of her more combative pieces, “a man came to tell me my music was ‘very fresh, flowery and sweet’”, she told AFP.

“I am a woman, so clearly those three words” apply, she said wryly. 

Pepin, whose music recalls both Claude Debussy and American minimalist composers like John Adams, said sometimes the sexist stereotypes which persist in the classical music world are hard to take.

 

Only woman

 

One “old school” music professor insisted she sit on his right at lunch “because that was a woman’s place” and sent her off to make the coffee.

“I was the only woman in all my classes in the Conservatoire, and it was fine,” said Pepin, who is now working on her first ballet score, in her Paris apartment which doubles as a studio.

Mostly the young composer, who made her breakthrough with the orchestral piece “Vajrayana” in 2015, said she was treated exactly the same as her male colleagues in classes with French contemporary composers like Guillaume Connesson, Thierry Escaich and Marc-Andre Dalbavie.

Beyond the classroom, however, progress is slow in the conservative world of classical music. 

Pepin believes it will take generations for the forgotten work of female composers to get just recognition.

Beyond the casual unthinking sexism, she said the biggest problem for young female composers was “a lack of role models”.

A few woman, such as the American composer Meredith Monk, Kaija Saariaho of Finland and Tansy Davies from Britain, have managed to break the glass ceiling.

 

Written out of history

 

But even Pepin admitted that when she was younger she did not know of a single female composer. 

“We never studied them,” she said. 

Who has ever heard of Helene de Montgeroult (1764-1836), Louise Farrenc (1804-1875) or Fanny Mendelssohn (1805-1847)? 

Fanny was the older sister of the more famous Felix Mendelssohn, with many at the time saying her work was more expressive.

But after she married, she was limited to domestic duties and had to content herself with being her brother’s chief editor and muse, which led him to call her his “Minerva” of wisdom.

“Lots of female composers were crushed like Clara Schumann [the wife of Robert Schumann],” despite being one of the most distinguished composers and musicians of the Romantic era, said the pianist Celia Oneto Bensaid, who often performs Pepin’s work.

“You play my music,” Schumann once bluntly told his wife, a star of concert halls across Europe.

 

Began at age 13

 

Born into a family in the northern French city of Amiens that was not particularly musical, Pepin began to write her own melodies at 13. 

But even at the age of five in her ballet class, her eyes were more drawn to the piano.

“I was so fascinated that I would forget to do my exercises,” she said.

Before settling on composing, Pepin thought about being a dancer. “I need to feel the notes physically,” she said. 

Her first ballet will be choreographed next year by Sylvain Pad for France’s Ballet du Nord.

Finally, she feels she is getting beyond the dreaded question — “But what do you do for a living?” — when she tells people she is a composer.

“They thought it was just something I did to chill on Sundays,” she laughed.

Automatic translation — better, but still not there yet

With increasing globalisation and a shrinking Earth, speaking, or at least understanding, several foreign languages is not a luxury anymore — it is a real must. We now need to communicate with speakers of other languages more  frequently faster and better. The question is more important than ever.

Software in general and the web in particular, have brought numerous tools that help you achieve, even if not perfectly yet, the trick. They range from text-based translation to instant voice processing. As an example, the new Travis Touch pocket translator is a handheld device, the size of a small smartphone, that listens to what you would say in a given language, instantly translates what you just said and then speaks it out loud in its own voice, in the chosen target language. The main languages processed by the Travis Touch are Arabic, English, Chinese, French, German, Spanish, and Japanese. This covers quite a large part of the world’s population!

How much are Travis Touch and the like able to do at this stage? It all remains simple, merely handling straightforward, non-equivocal, non-idiomatic talk. Some call it “touristic style”. PcMag reviewer Kevin Sebastian said of it: “don’t expect to have deep insightful conversations”. He further explained that the unit uses a “Wi-Fi signal that connects to a language database that works with real translators”.

Acknowledging what automatic translators can, and cannot, do is key to using them smartly and to avoid being disappointed. While the new, automated tools can be practical, proper human translation is still very much in demand, and only this kind can deliver properly formulated output, with correct grammar, syntax and hopefully style. 

In parallel, and in the same vein, countless ads can be seen on the web that promise to teach you a new language in a few weeks. Babbel is an e-learning much-publicised German platform that just does that. How much-exactly you can learn with it in a few weeks is another story.

Even the good old text-based tools such as Google Translate have been significantly improved. Those looking for a little more than just to understand what the text they are reading is about can use specialised websites or tools that deal with context-based translation, resulting in translated text that is much more accurate than what the general purpose Google Translate can deliver. For instance: Linguee, Al Maani (Arabic for “the meanings”) or Reverso, to name only three of them.

There is little doubt about the great utility of all these tools. They keep being improved constantly and over short periods of time. Sometimes the improvement can be felt in a matter of a few months. And yet, and again, human translators can do much better, but of course, they would take more time, and needless to say, more money to do it.

Professional human translators sometimes use the output generated by great sites to obtain a first draft, therefore saving precious time this way, if only in typing, and then edit the output to come up with more perfect language, grammar and syntax. It takes skills, art, wide general knowledge and culture to do that well.

Automatic, instant, multilingual, spoken, written, all these attributes of the connected digital world can do wonders to make the world unite and communicate faster, better and in an easier manner. Knowing the limits and remembering that automation can sometimes make serious misinterpretation with dire consequences means it always must be used carefully and wisely.

In the meantime, and until the day we see the United Nations replace their highly skilled, highly paid human interpreters with automatic digital devices at conferences and UN sessions, automatic translators will remain gadgets. Useful ones by all means, good helpers maybe, time savers and also perhaps fun to use, but gadgets nevertheless.
