太原夜生活The last 10 years have seen an onslaught of new medical discoveries and technologies, with many of them bordering on science fiction.
These discoveries have changed the way people live now and how they will live in the future.
Here are some of the biggest advances in medical science in the last decade — though this is by no means a complete list.
CRISPR gene editing
CRISPR is the name of a technique used to quickly and easily edit DNA — either snipping off genes entirely or replacing them with different ones.
The basic mechanism was discovered decades ago, but the technology has taken off in the last few years after it became more precise and easier to use. Right now, scientists are experimenting with editing the DNA of mosquitos to make them resistant to malaria or to make all offspring male, meaning they’re less likely to pass the disease on to humans.
Scientists have also treated sickle-cell anemia in mice and are testing a cure for an inherited form of blindness, and these are just some of many, many experiments underway.
Yes, we’re editing DNA now. Experts warn this won’t be without consequences. Studies have already shown that some CRISPR-edited cells get damaged and are missing a gene, leading to a potentially higher risk of cancer.
Then there are the ethical issues.
His experiments were not published in journals, nor were full results ever released, raising questions about the experiment. His claim was also roundly denounced by pretty much every medical body as well as the Chinese government.
But can we shut the door on human DNA editing? We’ll find out over the next decade.
Medications to treat HIV have been around for a while, and they’re very effective: drugs can actually reduce a person’s “viral load” — the amount of virus circulating in their blood — to undetectable levels. This means that it’s very unlikely, even impossible, for them to pass the virus on to others if the medication is used correctly. It’s also vastly extended the expected lifespan for someone following an HIV diagnosis.
In 2012, the U.S. Food and Drug Administration approved the use of an HIV drug for prophylactic purposes — meaning people could use it to actually keep from catching HIV in the first place. The drug, Truvada, which was approved by Health Canada for HIV prevention in 2016, and subsequent generic versions are now being used by high-risk populations across Canada.
So far, prescriptions for PrEP have lagged behind public health officials’ hopes — which might be due to spotty drug coverage and the high cost of the medication — but it has made a difference. A recent study found that PrEP use was associated with a significant reduction in the number of new infections in an Australian state.
Ebola vaccines and treatments
While we’re talking about infectious diseases, it’s definitely worth noting another big one: Ebola.
Ebola outbreaks are ongoing in a few African countries, mostly the Democratic Republic of Congo and Uganda. In 2014, a huge outbreak across West Africa killed more than 11,000 people.
However, over the last decade, we’ve seen clinical trials for various vaccines and even treatments for the disease, which are showing promising results. One vaccine, Ervebo, has even passed the clinical trial phase and was approved for use in November. It’s now being stockpiled for use in future outbreaks.
Although Ebola generally occurs far away from Canada, there is a Canadian connection: some vaccines and treatments were actually developed by researchers at the National Microbiology Lab in Winnipeg.
The term “artificial pancreas” is a bit of a misnomer, according to Diabetes Canada, but it’s the popular term for a device approved in the U.S. in 2016 and in Canada in 2018 to help treat patients with Type 1 diabetes. It’s more formally called a “closed-loop” system.
People with Type 1 diabetes no longer produce insulin. They used to have to take injections of insulin throughout the day to regulate their blood sugar and cut their risk of developing longer-term health problems like nerve issues that can lead to amputation or retinal problems leading to blindness.
Many patients have since moved on to more modern insulin pumps and testing devices.
This device makes things even easier. It first reads a patient’s insulin level, then decides via algorithm how much insulin to give them, shooting “microdoses” of the drug into their bloodstream automatically. The patient still has to add extra insulin in a few other circumstances, such as before a meal, but studies report these systems often lead to better control of blood sugar levels.
Diabetes advocates are looking forward to the development of a fully automatic system or a true “artificial pancreas” that requires no intervention from the patient, and also for better insurance coverage of these advanced devices.
One of the coolest new technologies is 3D printing, in which an object is created bit by bit from a computer pattern. And it didn’t take long for medical researchers to see the potential.
Doctors have created a handful of 3D-printed organs and body parts, but over the last decade, 3D-printed prosthetics have really taken off.
Need a new hand? Just visit a website and you can download a blueprint for free, along with detailed instructions on how to size and build it. Seriously. There has been an open-source community for years, run largely by volunteers. The organization e-NABLE estimates that thousands of people around the world are now using these prosthetics.
They’re not perfect: the devices can break, and e-NABLE recommends that people work closely with a health-care provider as they use their new prosthetic. But they’re much cheaper than traditional models and can be made much faster, putting prosthetics in reach for more people around the world.
Experts imagine that the medical applications for 3D printing will continue to expand, with complex organs like a replacement heart possibly coming down the road.

太原桑Lady Gaga wore meat and Rihanna went naked, practically. Kate Middleton delivered royal wedding opulence and Billy Porter went viral in a tuxedo gown. There was the much-coveted Olivia Pope white coat, Lupita Nyong’o’s perfect powder blue Oscar gown and Karl Lagerfield’s embrace of athleisure.
The closing decade was ever-shifting in fashion. The most special moments among fashion editors had Rihanna and Beyonce top of mind as trendsetters, along with the Duchess of Cambridge; the Duchess of Sussex, Meghan Markle; and former first lady Michelle Obama.
Rachel Torgerson, senior fashion editor at Cosmopolitan, said it might seem easy to overlook the decade of 2010 to 2020 fashion-wise. Lady Gaga’s raw meat dress in 2010 at the MTV Video Music Awards was a much talked about exception.
“More definitive moments came before — the grungy ’90s, the Paris Hilton-drenched early aughts,” Torgerson said.
“But the truth is there were some majorly iconic sartorial instances that changed us forever during this time.”
“My jaw dropped to the floor when Rihanna sparkled onto the stage in an Adam Selman Swarovksi crystal ‘naked dress’ to receive her CFDA style icon award,” said Joyann King, executive editorial director of HarpersBazaar.com.
“It was as beautiful as it was provocative and began a trend that continues to rule the red carpet and our social feeds.”
Laurel Pantin, fashion features director of InStyle, agreed.
“I’ll never forget it. In my dreams, that’s what I look like and that’s what I’m wearing.”
The year was 2014. The following year, at the Met Gala, Beyonce donned Givenchy in another barely-there look, a long sheer design that relied on coverage from strategically placed embroidery and a smattering of sparkles, said Andrea Lavinthal, style and beauty director for People.
“It was somehow even more naked than all the other naked dresses that night,” she said.
Kate Middleton wore the house of McQueen to marry Prince William in 2011, more than a year after Alexander McQueen’s death.
The lace and ivory satin gown included a pinched-in bodice inspired by Victorian corsetry, a signature of McQueen, but it also evoked the wedding look of Grace Kelly. It was designed by his successor, Sarah Burton.
“Literally every bride wanted to look like her then, and many still do,” Torgerson said. “People are still requesting lookalikes.”
The same interest followed Markle into matrimony. The American actress wed Prince Harry in 2018 dressed in a boat-necked, long-sleeve stunner by Claire Waight Keller of Givenchy.
“In this decade, not only one but two of the U.K.’s spotlight princesses got married, which left the world pondering about who these women would choose to design their momentous wedding dresses,” said Shilpa Prabhakar Nadella, fashion market director for Glamour.
“Both have become style icons in their own right.”
As style icons go, few had as much impact as Obama, who caused dresses and other attire to sell out simply by putting them on and was a big booster of both fashion and diverse designers. Her choices often made headlines.
Lindsay Peoples Wagner, editor-in-chief of Teen Vogue, noted a particular Obama moment, this one by designer Tracy Reese, a rare African-American woman among top designers.
It was the pink sleeveless dress with specks of gold brocade that Obama wore for her speech at the Democratic National Convention in 2012.
“It was a historic moment of two iconic women coming together,” Peoples Wagner said. “I can still remember how the dress shimmered as she walked on that stage.”
Like Obama, Beyonce served a heaping plate of style throughout the decade.
There was her larger-than-life black hat and layered necklaces of Swarovski crystals, leather and gems in Formation, from her groundbreaking Lemonade visual album.
For her September 2018 Vogue cover, she was photographed by Tyler Mitchell in a huge floral headdress by Phil John Perry for Rebel Rebel. It was stunning and also historic: Mitchell became the first Black photographer to shoot a cover for the magazine.
“The photos were so dynamic and powerful,” Peoples Wagner said.
Rihanna, too, has endured.
Her bright yellow cape gown by Chinese couturier Guo Pei won the 2015 Met Gala and launched a thousand omelette memes, Hyland said.
“Only women who have the confidence of a queen could wear it,” Pei told Fashionista.com.
By the decade’s end, she would also become a powerful fashion and beauty mogul in her own right. Her Fenty Beauty line with its inclusive shades forced other brands to adopt a wider view, her Savage X Fenty lingerie line for all body types was cited as a reason for Victoria’s Secret’s drop in popularity, and she became the first Black woman to helm a luxury line for LVMH with Fenty.
Virgil Abloh, as creative director of Louis Vuitton’s menswear, also made history.
“Not only did he become one of the first Black men to take over such a position in fashion, but the self-taught designer and multi-hyphenate represented a democratization of the industry and a breaking down of boundaries previously in the way for those considered far outside the lines of the traditional fashion industry insiders,” said Brooke Bobb, senior fashion news writer for Vogue.com.
Legendary designer Lagerfeld died in February, but his faux supermarket show for Chanel in 2014 lives on.
“Karl Lagerfeld, who once equated sweatpants with ‘giving up,’ cheekily nodded to the athleisure industrial complex with intentionally holey sweatsuits and dad sneakers,” said Veronique Hyland, fashion features director for Elle.
“It came at a turning point in fashion, with the everyday becoming more aspirational and studied casualness becoming the order of the day, even for fashion week habitues. It was also prescient. These days, the Whole Foods aisle is our runway.”
Kerry Washington, buoyed by Scandal, and Porter, uplifted by Pose, helped define the decade as well.
“Scandal was pretty much everything after it debuted in 2012 and pretty much every adult woman wanted Olivia Pope’s polished, perfect style and crisp, white waterfall overcoat,” Torgerson said.
“These are the facts!”
Porter has provided more than a few moments but it’s his showstopping black velvet tuxedo gown by Christian Siriano that achieved his goal in February at the Oscars: A conversation about gender, race and fashion.
The top half was a classic men’s tuxedo jacket he wore with a bow tie and the bottom was a dramatic full skirt.
“Gender-neutral fashion and inclusion emerged as a key shift in the way designers approached creative direction and their businesses,” King said.
“Billy Porter’s tuxedo gown that went viral embodied this movement in the most glamorous way.”
Porter, the Black and gay breakout star of the boundary-expanding FX series, spent the awards season using fashion as political art. There were previous dresses and there was help from powerhouses Tom Ford and Michael Kors, along with smaller designers who embrace a greater gender fluidity in their collections and were thrilled to dress him.
“People are actually listening,” Porter told the Associated Press after the Oscars.
“I hope it opens up a dialogue of healing. I will always continue to do me.”

太原南昌生活From what your bump looks like to the foods you crave, every pregnancy is vastly different from the next.
The same is true for how much weight you need to gain to support your growing baby.
“There are some recommended ‘targets’ … but these are for women overall. There are always individual circumstances that can come into play,” said Dr. Kaberi Dasgupta, professor of medicine at McGill University in Montreal.
However, it’s true that during pregnancy, you could need to gain extra weight in order to sustain both your life and that of the baby.
It’s also possible to gain too much weight, which can be associated with other risks.
“The idea behind [the guidelines] is that if you carry some extra weight before pregnancy, your body will be able to use some of these extra stores for energy so you don’t have to gain as much as weight,” said Dasgupta.
“If you don’t carry enough weight to begin with, you need to gain more … but no matter what, you still need to eat enough protein, vitamins and minerals so your baby and body have the building blocks needed.”
Recommended weight gain targets
When you’re pregnant, you will naturally gain weight as the baby grows.
“It’s the fluid around the baby — the amniotic fluid volume — and also each woman has about an extra litre of fluid running in their blood vessels,” said Dr. Jillian Coolen, maternal fetal medicine specialist at the IWK Health Centre in Halifax.
According to the IOM, what is considered a “healthy” amount of weight gain will be based on your pre-pregnancy weight and body mass index (BMI).
Your BMI is calculated by taking your weight in kilograms divided by the square of your height in metres.
This doesn’t mean you should gain all the weight at once, according to Rebecca Krukowski, an associate professor in the department of preventative medicine at the University of Tennessee.
“It’s recommended that women remain ‘weight stable’ in the first trimester,” she said.“In the second and third trimester, it’s recommended that women gain about 0.5 kg per week if they are in [the first two categories] and about 0.25 kg per week if they are in the [latter two categories.]”
It’s also important to note that this doesn’t mean women who gain more or less than the recommended amount of weight will have an unhealthy pregnancy or birth, according to Health Canada.
Many other factors, including smoking, maternal age and underlying illness, can affect pregnancy outcomes.
To learn more, use the Health Canada calculator to determine both your pre-pregnancy BMI and your recommended weight gain amount.
The risks associated with gaining ‘too much’ or ‘not enough’
The risks associated with gaining too much weight are “well-documented,” said Coolen.
Possible outcomes include giving birth to a “large for gestational age” infant, gestational diabetes and hypertensive disorders, such as preeclampsia. You’re also at an increased risk of postpartum weight retention, which can have implications for future pregnancies and your life in general.“Gestational diabetes has an increased risk of a big baby … and of extra amniotic fluid around the baby, both of which increase your risk of a pre-term birth [by] putting pressure on your cervix,” Coolen said.
It can also increase your risk of high blood pressure, which can lead to early delivery and other conditions for the mom.
“Both gestational diabetes and blood pressure have an increased risk of stillbirth, and with gestational diabetes, there’s an increased risk for the baby to have low blood sugar and jaundice after birth,” she said.“If your baby is [above the average weight], that increases your risk of caesarean section and … trauma for both mom and baby,” said Coolen.
There’s less known about the possible affects of not gaining enough weight during a pregnancy, said Coolen.
However, Dasgupta said there’s some evidence to suggest that gaining too little can increase your risk of having a baby “who may be too small,” as well as premature delivery.
How to stay healthy during pregnancy
If you’re worried about your weight during pregnancy, Coolen recommends meeting with a registered dietitian.“They can give you advice about gestational gain, look at and give you some tips and tricks,” she said. “Then they can track [your progress] with you.”
Dasgupta agrees, saying a healthy diet of mostly vegetables, fruit and protein is key to a good pregnancy.
“You’re not eating for two — you’re eating for you and a little developing baby,” she said.
“Be careful about giving into cravings for less healthy foods like sweets and chips.”
She also recommends trying to eat regularly throughout the day, instead of all at once.
“At least three meals and maybe a snack or two, rather than cramming all your food into one or two meals,” said Dasgupta.
Most physical activity is safe for expectant mothers, but you should always check with your doctor before trying anything new.“You should always check with your doctor first, because there are certain conditions like a placenta previa … which [could cause] activity to be restricted,” said Coolen.
“If you’re allowed to exercise … don’t overheat. Stay hydrated. Exercise to about 70 per cent of your max heart rate.”
She also recommends avoiding “high-risk activities where trauma could happen,” like horseback riding, contact sports and scuba diving.

太原丰富桑拿Whistler, the famed ski town north of Vancouver, has known for at least five years that its tap water is corrosive, increasing the risk for lead and copper leaching into drinking water in homes and hotels.
However, the town says more time is needed to study how to fix the problem.
The resort municipality, which prides itself on having “safe, affordable, and environmentally friendly” drinking water, urges its residents and almost three million yearly visitors to drink from the tap and help cut down on plastic waste.
There’s just one caveat: Officials say they should run the water until it’s cold before drinking.
Whistler’s water flows from the snow on Rainbow Mountain to the 21 Mile Creek Watershed, but during periods of heavy rainfall, the utility pulls groundwater from 15 wells instead.
The water tends to be acidic, increasing the risk that lead, a neurotoxin, will leach from residential or commercial plumbing.
As a part of a collaboration among Canadian universities and media partners, including Concordia University’s Institute for Investigative Journalism, Global News and Star Vancouver, reporters from the University of British Columbia collected water samples from 10 homes, two hotels and one Airbnb property in Whistler and had them tested for lead at an accredited lab.
All of the samples contained traces of lead and seven contained lead levels exceeding Health Canada’s guideline of five parts per billion (ppb). In addition, samples collected from one hotel room and another home rented through Airbnb also exceeded the recommended federal limit.
Whistler is one of more than 20 communities in B.C. that may be at higher risk of having lead leaching into their water due to a combination of acidic water and old pipes and plumbing fixtures.
These water systems were among more than 30 surveyed by reporters, some of which were highlighted by a water intelligence company, WatrHub, that designed an algorithm using key search terms such as “lead” and “pH” to identify communities most at risk lead-tainted tap water.
Reporters narrowed down this list by examining key indicators, such as identifying which operators had drinking water that, at times, failed to meet the federal guideline for a pH level ranging between seven and 10.5. The reporters also sent questions to the water operators about their systems, from Vancouver Island to the Interior, while reviewing annual drinking water reports and testing data.
The data available varied considerably. Some small water systems had reported just one or a few pH readings for the year most recently available, while others had a few dozen samples available.
The results of the survey expose “a complete void in the regulations,” said Michèle Prévost, a civil engineering professor from Polytechnique Montreal.
She noted that mandatory testing for lead in drinking water is a first step toward protecting public health: “If you don’t know how much, you don’t know if you have a problem. If you don’t know if you have a problem, then you can’t fix it.”
After reviewing the results of the survey, B.C.’s Ministry of Health responded that “British Columbians enjoy some of the cleanest and safest drinking water in the world.”
Nevertheless, “homeowners are responsible for managing their private infrastructure against all risks, including lead in water,” the ministry added.
Lead is odourless, colourless and tasteless when dissolved in water.
In Whistler, the team of students tested tap water in buildings constructed between 1968 and 1994. These were selected in order to measure the levels of lead in homes where residents are most likely to be at risk, in line with Health Canada’s recommendation that water operators focus on older buildings and other areas of concern.
The highest lead concentration, 61 ppb — 12 times the federal guideline — was detected in water from a kitchen tap in a rental home built in 1974, where John Wallace, a 37-year-old welder fabricator, lives with his wife, two-year-old son, and their dog, Bailey.
“There’s a concern that it will impact my son,” he said. “There’s a concern that everything will impact my son a little bit.”
Wallace said he hadn’t been aware previously that he needed to flush the taps before consuming the water.
“It’s going to change the way I deal with my water,” he said. “When I wake up in the morning I’m going to let that run for a minute or two, I’m going to use better filters, and I’m going to eliminate that problem.”
The resort municipality began replacing affected water mains with PVC pipes, but hasn’t yet moved to raise its water’s pH.
Meanwhile, the Village of Pemberton, 30 kilometres away, took steps to address its corrosive water after municipal testing detected elevated lead levels in drinking water at local homes in 2016.
Lead levels as high as 107 ppb were detected, according to documents obtained through freedom of information. The next year, Pemberton completed a soda ash conditioning system that injects sodium carbonate into the water system to both raise the pH and address its corrosivity problem.
Whistler Mayor Jack Crompton explained Whistler is expecting a new report in 2020 and is still trying to understand the implications of such a decision.
“We want to make sure that we’re well informed when we make a decision like that,” he said, adding that there are jurisdictions that still recommend flushing the taps even after adding chemicals to address corrosion.
Lowe said the hotel would conduct its own tests as well, noting “the health and safety of our guests and employees is our primary concern.”
If the resort municipality moved to raise the water’s pH, it would bring down the first-draw results detected at the hotels, according Prévost, the civil engineering professor from Polytechnique Montreal.
Theresa McClenaghan, executive director and legal counsel of the Canadian Environmental Law Association, says B.C. and other provinces should adopt similar rules to Ontario, which makes it mandatory for utilities to control corrosion when they are deemed to be at risk.
“That is what I think B.C. and every other province who hasn’t done that yet, needs to do,” she said in an interview.
“Because of the fact that the water utility is the one in control of the plant, in control of the chemistry, in control of making decisions about what types of treatment to deploy… residents have zero control over that and zero knowledge unless they are extremely technically savvy.”

太原夜网论坛Before Shefali Burns and her husband divorced, some people couldn’t even picture them together.
When Burns, a North Indian woman, and her ex-husband, a white man, went to restaurants together with their children, staff would assume her husband wasn’t part of the family.
“People would look at us and then not realize we were all together,” said Burns, who grew up in Ottawa. “So there was always that separation that was always there, even though we were a family unit.”
“It really stuck out that we were two different races, that we were two different colours,” she said. “That was like a disconnect… People are still not used to seeing interracial families.”
Couples from two different races and backgrounds can face a multitude of issues that same-race couples don’t always deal with, explained Burns, who works as an author and consultant now in Vienna, Austria.
Burns and her husband were married in 1993 and got divorced 18 years later in 2011. In the same year, a census report found that 4.6 per cent of Canadians were in mixed unions, which was the last time this data was calculated.
“There was more pressure to stay together because of the different races and cultures,” she said. “And when I finally got divorced … I had no support from anybody, other than my kids.”
Her side of the family didn’t support the idea of divorce and her husband’s family didn’t either, she said. “In the Indian culture, you don’t get divorced, no matter what.”
But along with the pressure from both families to work out their relationship, Burns felt that her husband didn’t treat her culture and traditions as equal to his own.
“My husband never fully accepted the culture or the religion or some traditions,” she said. “He never really fully participated … even though I was fully into Christmas and everything else.”
The relationship was also exoticized by family members, which made her feel strange, she said.
“It’s like they just thought it was so exotic, that I’m from a different culture and a different race,” she said.
“I’m still considered different. But I’m not… I’m me,” she said. “Can you not just see me?”
In Canada, many consider interracial couples a symbol of the country being more open-minded, inclusive and multicultural.
Interracial couples do face additional pressures, as their unions do not exist in a vacuum — Canada is a country where racism exists, and those couples will have to confront those issues, said Tamari Kitossa, an associate sociology professor at Brock University in St. Catharines, Ont.
How an interracial couple is treated will change based on factors like where they live and how diverse the community they live in is, he said.
“They will be visible in different sorts of ways. And that might have different sorts of impacts on their unions,” he said.
But beyond the dynamics of a couple’s own relationship and whether they are able to accept each other’s differences, they also have to confront beliefs in Canada that mixed unions are utopian and a symbol of an ideal multicultural society, he said.
Kitossa’s research, performed alongside assistant professor Kathy Delivosky, examines why interracial marriages are viewed as “anti-racist” and are propped up as “progressive.”
“Canada is marketing itself in a globalized world as a go-to place for immigrants,” he said.
But at the same time, some white people are creating a narrative that they are being marginalized and are facing a demographic decline. Around 80 per cent of Canada’s population did not identify as a visible minority in 2011.
“This is creating a toxic brew, for making people in interracial relationships much more visible and exposing them to social pressure,” he said.
Burns said interracial relationships, like any relationship, are not perfect.
“Even interracial couples, they have problems just like any other couple,” Burns said. “Just because they’re from two different races does not make them any more open, or better.”
For anyone who knows an interracial couple, support them in open communication and understand that they may be facing serious issues. Ask how you can help, Burns recommended.
Data on marriage no longer collected
Statistics Canada stopped collecting data on marriages, making it difficult to discern the divorce rate of interracial couples and to identify concerns, said Kitossa. The national statistical office confirmed to Global News that it no longer collects data on marriage and divorce.
Harmsen recalls travelling to the U.S. with her family and the drive across the border being smoother if her father was in the driver’s seat. They would get stopped if her mother was driving, she said.
Those microaggressions and communication about them might have been missing from her parents’ relationship, she said.
“That was definitely a factor, for sure,” she said.
Interracial couples are often portrayed in film and media as only having to overcome initial family discomfort that’s all solved after they get married, suggesting that love conquers racism, Harmsen explained in her piece.
Removing those kinds of expectations on interracial unions is important, she said, as that pressure can harm the relationship.
太原桑网夜Periods can cause cramping, mood swings and acne, but they can also wreak havoc on your digestive system.
“Period poops,” as they are often called, refer to bowel movements that coincide with the start of your period. They typically differ from your regular poops and are often looser and more frequent, or diarrhea.
According to Dr. Yolanda Kirkham, an obstetrician-gynecologist at Women’s College Hospital and St. Joseph’s Health Centre in Toronto, hormones are largely to blame.
“Some of the same hormones that cause cramps and inflammation also lead to some of the bowel changes,” Kirkham explained.
During your period, prostaglandins — a group of hormones — cause uterine muscle contractions, or cramps. Kirkham says prostaglandins can also cause contractions in the intestines.
“When you have excessive bowel cramps, you can also have diarrhea,” she said.
Premenstrual syndrome (PMS) symptoms can also affect your bathroom schedule, Kirkham said. If you experience higher levels of anxiety around your period, for example, the hormones related to stress can cause bowel movement changes.
Loose poops are only one menstrual-related digestive change; many women experience constipation before they bleed.
Kirkham says there’s an increase in progesterone just before periods begin, which is the hormone that thins the uterine lining.
“It also causes some of our other PMS symptoms, like mood symptoms and acne. It can cause some constipation as well,” she said.
How to manage period poops
There are some over-the-counter ways to deal with digestive changes, Kirkham said.
These include nonsteroidal anti-inflammatory medications, such as ibuprofen.
“Even before you see the menstrual blood, if you start to have cramps, you can start taking those medications,” Kirkham said.
The doctor also stresses that a balanced, healthy diet rich with fruits and vegetables is key, as is exercise.
“Then there’s also all of the menstrual management medications we use, such as birth control pills, patches and the ring,” she said. “Those both decrease period cramps and period flow… and will also help with the symptoms.”
When to see a doctor
While period poops may be normal, you should seek medical counsel if you experience any changes, including blood in your stool or rectal or anal pain.
These may be symptoms of other issues, such as inflammatory bowel disease, hemorrhoids or endometriosis, said Kirkham.“If you’ve got more pain, more than just a change in [bowel movement] texture or bleeding, those should definitely be checked out.”

太原夜网Sleep affects every aspect of your health, from your mood to memory to exercise habits.
It’s widely known that sleep deprivation is harmful in myriad ways — but now, new research shows that over-sleeping is damaging, too.
Regularly sleeping for more than nine hours at a time and taking long midday naps has been shown to increase a person’s risk of stroke, according to a study published in Neurology on Wednesday.
Researchers analyzed the sleep patterns of 31,750 people in China over six years. The average age was 62, and the study controlled for other stroke risk factors, like smoking, drinking, and history of stroke and other heart issues.
Respondents who slept more than nine hours per night had a 23 per cent higher risk of stroke. Those who frequently had a midday nap longer than 90 minutes experienced a 25 per cent increase in risk.
For people who slept for longer than nine hours and had a midday nap longer than 90 minutes, the risk of stroke jumped to a whopping 85 per cent.
The reason behind the association is unclear to researchers, but they did note that increased sleep duration was also related to increased inflammation and weight, among other factors known to negatively affect the heart.
Sleep has a “bi-modal distribution,” said Sheila Garland, a registered clinical psychologist and an assistant professor at Memorial University in Newfoundland and Labrador. This means there are two modes of sleeping: too little and too much.
“It’s not good to sleep too little, but it’s also not good to sleep too much,” she said.
A vicious cycle
The trouble for researchers is excess sleep can be both a cause and a symptom: It can cause other health problems to occur, but it can also be a symptom of other underlying health conditions.
It’s a vicious cycle, said Garland.
“It’s tricky because you don’t know whether it’s compromised by health conditions that existed prior … making it more likely that you’re going to increase your sleep duration, or that the increase in duration itself makes you more likely to have health conditions,” she said.
Sleep disorders like hypersomnia and sleep apnea can affect the length of a person’s sleep cycle. Mood disorders are another common culprit.
“Often, people with mood disorders like depression will see an increase in the amount of time that they sleep,” Garland said. “One of the key characteristics of depression is too little or excessive sleep. That needs to be considered.”
In determining why someone is sleeping too much (or too little), both physical and psychological conditions should be considered.
Charles Morin, behavioural sleep medicine researcher and professor at the University of Laval in Quebec City, has seen this scenario many times before.
“We long thought that insomnia was just a symptom of depression, and if we treated the depression, it would take care of the insomnia problem automatically,” he said. “That isn’t the case.”
People without depression can develop insomnia, but the sleep condition can greatly increase their risk of developing depression later on, said Morin.
“If someone now is struggling with depression and insomnia, we recommend that they receive treatment for both conditions,” he said.
The circadian rhythm
Sleep is one of the three “critical pillars of health,” along with good nutrition and exercise, said Morin.
What constitutes a good night’s sleep is different for everyone, but for the most part, adults should get seven to eight hours of sleep a night, he said.
It’s totally normal to need slightly less (five to six hours) or slightly more (nine hours), but this isn’t the average experience. If you sleep for 10 hours at night and still feel tired the next day, Morin suggests you see a doctor.
Garland says good sleep has three components: “enough sleep duration,” “good sleep quality” and it’s “appropriately timed.”
This means you’re listening to and following your circadian rhythm — a function of the brain that controls the responses when your body does certain things with hormones.
“It tells us when to be awake and when to be asleep, and it influences the production of hormones,” said Garland. “Every cell has a clock that tells it to turn on and turn off.”
“Every living thing has the machinery in all of its cells, including our human brains, to recognize the rising and the setting of the sun,” Richard Horner, a professor of physiology at the University of Toronto, previously told Global News.
He said our bodies take cues from the light around us to figure out when it’s day or night, and that influences when we want to sleep or wake up. Bright lights in the morning can “reset” your personal circadian rhythm so you can be certain it’s on the right schedule.
Some people prefer to wake up early and go to sleep early, while others like to stay up late and rise later, too. These concepts aren’t just in our heads, said Garland.
“They’re genetically determined and, if you try to work against your genetics, it can be very hard on your body,” she said. That’s why people who work shifts or overnight often have more health problems than those who don’t.
“They’re basically working against their circadian rhythm,” said Garland. “They’re being awake when their body really wants them to be asleep.”
Sleeping the right amount
If you’re worried that you might be over-sleeping, Garland recommends trying to cut back over a two-week period.
“See if it actually makes you feel better,” she said. “But it needs to be consistent. The most important thing would be for people to get a wake-up time that’s consistent.”
If you don’t feel any different after the change, or if it was nearly impossible to alter your sleep pattern, Garland recommends seeing a doctor.
太原桑拿夜生活网丰富Under pressure from a conservative advocacy group, The Hallmark Channel has pulled ads for a wedding-planning website that featured two brides kissing at the altar.
The family-friendly network, which is in the midst of its heavily watched holiday programming, removed the ads because the controversy was a distraction, a spokesperson said in an interview Saturday.
“The debate surrounding these commercials on all sides was distracting from the purpose of our network, which is to provide entertainment value,” said a statement provided by Molly Biwer, senior vice president for public affairs and communications at Hallmark.
In an interview, she added: “The Hallmark brand is never going to be divisive. We don’t want to generate controversy, we’ve tried very hard to stay out of it … we just felt it was in the best interest of the brand to pull them and not continue to generate controversy.”
There was immediate criticism on Twitter. Ellen DeGeneres asked Hallmark: “Isn’t it almost 2020? What are you thinking? Please explain. We’re all ears.”
Biwer confirmed that a conservative group, One Million Moms, part of the American Family Association, had complained about the ads to Bill Abbott, CEO of Crown Media Family Networks, Hallmark’s parent company.
A post on the group’s website said that Abbott “reported the advertisement aired in error.” The group also wrote: “The call to our office gave us the opportunity to confirm the Hallmark Channel will continue to be a safe and family-friendly network.”
Zola had submitted six ads, and four had a lesbian couple. After Hallmark pulled those ads, but not two featuring only opposite-sex couples, Zola pulled its remaining ads, the company said.
“The only difference between the commercials that were flagged and the ones that were approved was that the commercials that did not meet Hallmark’s standards included a lesbian couple kissing,” said Mike Chi, Zola’s chief marketing officer, in a statement sent to the AP. Hallmark approved a commercial where a heterosexual couple kissed.
“All kisses, couples and marriages are equal celebrations of love and we will no longer be advertising on Hallmark,” Chi said.
In one of the pulled ads, two brides stand at the altar and wonder aloud whether their wedding would be going more smoothly if they had used a wedding planning site like Zola. The lighthearted ad ends with the two brides sharing a quick kiss on the altar.
Actress Sandra Bernhard, who played one of the first openly bisexual characters on network TV in “Roseanne,” also criticized Hallmark’s decision.
“All the groovy gay ladies i know won’t be watching your Christmas schlock,” she wrote on Twitter, addressing Hallmark. “They’ll be out celebrating with their ’families’ wives, children, friends on & on & getting married in chic ensembles. Didn’t you all get the memo? Family is all inclusive.”
The developments came as Hallmark appeared to be considering more same-sex themed content.
Asked about the possibility of holiday movies based on same-sex relationships, Abbott was quoted in The Hollywood Reporter in mid-November as saying on its TV podcast: “We’re open to really any type of movie of any type of relationship.”

太原桑拿论坛是The way you dress can have an effect on whether or not people think you’re competent, a new study suggests. Researchers said these judgments take place in a matter of milliseconds.
The study was conducted by researchers at Princeton University and was published in the Nature Human Behaviour journal on Monday. It aimed to show how something as nuanced as the subtle economic status cues in clothes can impact perception.
“Your snapshot judgments of competence, even when you don’t know the person at all can predict a lot of important social outcomes, like who becomes a CEO of a big company and who doesn’t,” DongWon Oh, lead author of the study, said in an interview.
“We found the economic cues are really hard, if not impossible to ignore.”
Oh and team started the experiment with images of 50 people’s faces. They were each wearing clothes rated as “richer” or “poorer” by an independent group of judges who were asked, “How rich or poor does this person look?”
Based on those ratings, the researchers selected 18 black and 18 white subjects displaying the most prominent rich-poor differences. Those images were then used across nine slightly tweaked versions of the same study.
Study participants were asked to rate the competence of faces shown in photos.
Regardless of what was worn in the images, researchers found that clothing perceived as “richer” by a participant led to higher competence ratings of the person pictured than similar clothes judged as “poorer.”
Participants saw the images for three different lengths of time, ranging from about one second to approximately 130 milliseconds.
Their reactions were “non-deliberate, and triggered by brief exposure,” researchers said.
Several studies included modifications to the original design.
In some iterations, they replaced all suits and ties with non-formal clothing. In others, they told participants there was no relationship between clothes and competence.
In one study, the researchers provided information about the person’s profession and income to minimize potential inferences from clothing.
In another, they expanded the participant pool to nearly 200, and explicitly instructed participants to ignore the clothing.
Regardless of these changes, the ratings remained consistent. Faces were judged as significantly more competent when the clothing was perceived as “richer.”
Oh said there were limitations to the study.
“This is a very controlled situation where you only see the visual images and it’s a static image, so it’s pretty stripped out,” he said.
Oh said results could differ drastically in real-life situations where someone had previously heard about a person from a friend, read about someone’s accomplishments online or were forced to spend longer amounts of time with them than allotted in his study.
They also found that physically attractive people were viewed as more competent, which affected the way Oh’s team selected their subjects.
Determining why certain types of clothes are viewed as “richer,” how facial features factor in, and how individuals come to these conclusions will need to be examined, said Oh.
But in a world where Instagram and Facebook can act as the first impression, making such judgments may be difficult to unlearn.
“Under certain circumstances, where you only see photos of other people in either richer versus poor-looking clothes, it seems very hard to reverse these kinds of biases,” said Oh.
