排放量去年的增幅比过去十年中2.5%的平均增长率略低,而且排放量增幅之所以下降,很大程度上是由中国经济增长放缓所引起的。中国是世界上最大的温室气体排放国。可能还需要再花一到两年时间,才能弄清楚中国排放量的增长究竟有没有放缓,还是最近数年那种极高的增速仍会持续。

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.

In early 2005, Stone and her co-founders Elisa Camahort Page and Jory Des Jardins noticed that there were countless women blogging, but mainstream media rarely linked to their posts. The trio decided to host a grassroots conference that year and attracted sponsors like Google and Yahoo. It quickly sold out and soon after, they launched BlogHer.com. The publishing platform turned blogging into a lucrative business for many women -- it paid $25 million to 5,000 of its bloggers between 2009 and 2012 -- and now reaches an audience of 92 million.
