Exports from China to Brazil of everything from cars to textiles shipped in containers fell 60 per cent in January from a year earlier while the total volume of imports via containers into Latin America’s biggest economy halved, according to Maersk Line, the world’s largest shipping company.

Current prosthetic hands do little beyond filling the arm-shaped space between your body and the air. Sure, they can grasp things all right, and they help in balance, but they lack one of the human hand's most important abilities—the sense of touch. People with prosthetics can't detect if they're in contact with an object without looking at it directly.

The survey discusses projections for going forward: "The cost of living is always changing and there are already indications of further changes that are set to take place during the coming year."
After years working with large consumer product companies like Stride Rite and Keds, Pieri grew frustrated with the difficulty mom-and-pop shops had launching new products. "The more innovative a product—as opposed to mainstream and "known"—the harder it was to get distribution," she explains. In response, she launched The Grommet, a discovery platform that connects customers with inventors' stories and their products, five years ago. Pieri, whose company helped launch products including SodaStream and Fitbit, counts HP CEO Meg Whitman as a mentor and has a side-gig as an entrepreneur in residence at Harvard Business School.
But, when the skeletal remains were analyzed, the researchers found that the tombs had been reused multiple times. Some of the tombs contain more than 10 occupants, and the"repeated multiple burials warrant further study," the researcherswrote.
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.
