Forget the Bezos and Branson Spaceflights. The Real Deal Happens This Fall

This has been a big month for billionaires in space. On July 11, Richard Branson flew aboard his Virgin Galactic VSS Unity spacecraft 80 km (50 mi) up to suborbital altitude, returned safely to Earth, and earned his astronaut wings in the process. Tuesday morning, Jeff Bezos followed, flying his Blue Origin New Shepard ship even higher—100 km (62 mi) up—and similarly joined the astronaut club. The media did what the media will always do in situations like this—present company included—which was to find a catchy hook (Billionaire Space Race!) and devote no end of coverage to the Branson-Bezos doings. And with good reason: the technology is nifty, the achievements are real, and both Blue Origin and Virgin Galactic aim to open the flights to the public too—or at least the vanishingly small portion of the public that can afford a six-figure fare for little more than a 10-minute flight to and from space. [time-brightcove not-tgx=”true”] But the storm of press has thus far largely overlooked a much bigger space deal coming in September, when yet another billionaire—Jared Isaacman, the CEO of Shift4 Payments, an online payments company—goes aloft with three other civilian astronauts aboard a SpaceX Crew Dragon spacecraft in a mission dubbed Inspiration4. Never mind 10 suborbital minutes, this will be a three-day trip to orbital space at an altitude higher than that of the International Space Station (ISS). And never mind the idea...

The aim of this study is to evaluate risk factors contributing to the development of ototoxicity in children who received platinum-based chemotherapy for malignancies located in the head and neck region. Eighty-four children who received platinum-based chemotherapy were included. Audiologic evaluations were performed before and after each chemotherapy session through pure tone audiometry, distortion product otoacoustic emissions, and auditory brainstem response tests. Ototoxicity was evaluated using Brock, Muenster, and Chang classifications. Factors such as cranial irradiation, cumulative doses of cisplatin, age, sex, cot...

This study suggests that breastfeeding neither impacts the sporadic development nor is associated with a decrease in the severity of nonhereditary RB as measured by age at diagnosis, stage of disease, ocular prognosis, and extraocular spread. A further exploration into the impact of diet on children who develop RB is warranted.

Environ Int. 2021 Sep 18;158:106877. doi: 10.1016/j.envint.2021.106877. Online ahead of print.ABSTRACTHexavalent chromium [Cr(VI)] is a global environmental pollutant that increases risk for several types of cancers and is increasingly being recognized as a neurotoxicant. Traditionally, the brain has been viewed as a largely post-mitotic organ due to its specialized composition of neurons, and consequently, clastogenic effects were not considered in neurotoxicology. Today, we understand the brain is composed of at least eight distinct cell types - most of which continue mitotic activity throughout lifespan. We have learned...

In conclusion, there is growing evidence from epidemiological data that CT scans can cause cancer. The absolute risks to individual patients are, however, likely to be small. Ongoing large multicenter cohorts and future pooling efforts will provide more precise risk quantification.PMID:34545766 | DOI:10.1259/bjr.20210471

We report a case of Maffucci syndrome withIDH1 mutation complicated by intrahepatic cholangiocarcinoma. The patient was a 35-year-old woman who was diagnosed with Maffucci syndrome in childhood. She was referred to our department because of a large hepatic tumor. Serum carcinoembryonic antigen was 27.1 ng/mL upon laboratory examination. CT scanning showed a large low-density tumor (90 × 70 mm) in the right lobe of the liver, and MRI revealed a multilobulated and fibrous tumor, which was observed as high signal intensity on T2- and diffusion-weighted images and low signal intensity on T1-weighted images. Positron emis...

World J Gastroenterol. 2021 Aug 28;27(32):5322-5340. doi: 10.3748/wjg.v27.i32.5322.ABSTRACTThe presence of pancreatic cancer during childhood is extremely rare, and physicians may be tempted to overlook this diagnosis based on age criteria. However, there are primary malignant pancreatic tumors encountered in pediatric patients, such as pancreatoblastoma, and tumors considered benign in general but may present a malignant potential, such as the solid pseudo-papillary tumor, insulinoma, gastrinoma, and vasoactive intestinal peptide secreting tumor. Their early diagnosis and management are of paramount importance since the s...
