In my life, I have dreamt of seeing the great herds of wild animals, jungles and rainforests full of birds and butterfilies, but now I wonder if they will even exist for my children to see. 我一生的梦想就是能看到成群的野生动物，茂盛的丛林和大片的雨林中到处是鸟类和蝴蝶在飞舞。但是现在我想知道我们这些小孩是否还能再看到它们？
这个领域的创新速度非常快。自从Fitbit于2008年成立以来，各家公司已经发布了五到六个完全不同的产品。三星（Samsung）则在九个月内发布了可穿戴设备Galaxy Gear的三到四个衍生产品。索尼（Sony）、Pebble、谷歌和Facebook的头戴式虚拟现实设备Oculus Rift也紧随其后。
Last week, Clinton campaign chairman John Podesta said that the former first lady's shortlist of potential running mates will include women, quickly leading to speculation that Clinton will consider Massachusetts Sen. Elizabeth Warren, a popular progressive, for an all-female ticket.
I experienced this pessimism personally in Davos in January 2014. Several leading western intellectuals asked me whether war would break out between China and Japan. I was so confident that there would be no war in east Asia that I offered to take bets with ten-to-one odds against myself with eminent western journalists. Two took up my bets. And I will be collecting on these bets when I return to Davos in January.
Swyft now makes half of its money from ad campaigns like the one for Gwen Stefani. Swyft’s revenue has increased between 50% and 100% each month, Wray says. The other half comes from selling stickers—typically licensed from sports teams and entertainment brands like Shrek.
The Warriors are one of the best teams in NBA history, and you can put their championship run up against any team in NBA history for the best playoff performance ever. But there's also a legitimate question of what this means for the sport. If the best or second-best player of all time stands no chance against this team, what does it mean for the sport's competitiveness? It hasn't been a problem so far, thanks to an extremely wild offseason, but the question remains: what happens to a competitive sports league when it's not truly competitive at the highest level?
In 2010, a 14-month-old child accidentally fell on a chopstick he had playfully placed into his nose. It did, indeed, puncture the roof of his nose and lodge into his brain. Neurosurgeons did successfully remove the chopstick, with little internal damage long term.
The nasal, or nasopharyngeal, swab for Covid-19 is a PCR (polymerase chain reaction) test looking for active infection, and remains the most accurate to date to assess for acutely infected individuals. This in contrast to the antigen, or rapid test, also performed as a nasopharyngeal swab, which is much less accurate, especially if the test result is negative (it has a very high false-negative rate). The antibody test, which is a blood test, is performed to detect evidence of prior infection, not active illness.
A 40-year-old woman in Iowa underwent a nasopharyngeal Covid-19 swab test as part of her preoperative clearance for an elective hernia repair. Soon after, she developed headache, nausea, vomiting, and clear watery drainage from the side of her nose where the swab had been placed. This was not the type of drainage one would get from allergies, a cold, or even a sinus infection. Picture your kitchen sink trickling out water if it’s not fully turned off. That’s what a spinal fluid leak can look like, which is what she had. In addition, the fact that a runny nose is just on one side is often a tip-off of something unusual. As published in the October issue of JAMA Otolaryngology, it turned out that she had had prior nasal polyp surgery two decades ago, as well as a history of disorder called intracranial hypertension, or increased pressure of the fluid surrounding the brain. The combination of these two entities led to a small defect in the bone between the roof of the nose and the brain, and she had developed a pocket of the brain’s lining prolapsing into the nose, known as an encephalocele. The sack of the encephalocele got nicked by the Covid-19 swab.
Radiologic imaging of her brain and sinuses demonstrated a one-inch area where there was no bony roof of her nose. Instead, there was an out-pouching of the brain’s lining, known as an encephalocele, filled with spinal fluid. The pouch got pierced by the swab, and just like piercing a water balloon that’s attached to a faucet, it immediately started leaking clear cerebrospinal fluid. Once this was identified, she underwent surgical repair of the defect in the bone, and the spinal fluid leak was controlled and repaired.
According to Dr. Jarrett Walsh, Assistant Professor of Otolaryngology-Head and Neck Surgery at the University of Iowa, and senior author of this report, “If the swab is introduced at an angle toward the skull base, then any defect in the skull base is potentially put at risk. Correct technique, following the floor of the nose, is exceptionally safe and will not cause skull base trauma.” When asked if he would recommend avoiding nasopharyngeal testing swabs in general, he thinks not: “Nasopharynx swabs, performed correctly, are safe...I think the group of patients that needs to exercise caution in testing are those who have had anterior (nasal) skull base surgery – specifically those who have had reconstruction of the anterior skull base. With missing bone between the nose and the brain, an errant swab could have significant consequences. This is the group that I would encourage considering an alternative testing technique, if it is available.”
When it comes to Covid-19 diagnostic testing, nasopharyngeal swab approach has been shown to be more accurate than oropharyngeal (oral) swab. However, in some cases, especially where a patient has had prior surgeries in the area between the nose and the brain, or prior injuries in that region, physicians will accept oropharyngeal testing for pre-procedure screening.
