What The Study Did: Study results suggest that reinfections are rare events and that patients who have recovered from COVID-19 have a lower risk of reinfection. However, the observation ended before SARS-CoV-2 variants began to spread, and it is unknown how well natural immunity to the wild-type virus will protect against variants. .

What The Study Did: Researchers estimated the extent Medicare Part B medical services would have been subject to prior authorization under private insurance coverage policies and calculated the associated spending.

As hospitals, insurance companies and policy makers seek to improve healthcare quality and reduce rising medical costs, one important metric used to assess clinicians hinges on how patients feel about their healthcare experience. Many healthcare providers and policy makers fear that increased pressure to please patients -- and ensure high satisfaction ratings as a result -- could lead to overuse of low-value care that doesn't provide any clinical benefit while unnecessarily ratcheting up medical bills.

MISSOULA - In bear country, it's normal to find bruins munching down on temptations left out by humans - from a backyard apple tree to leftovers in the trash bin - but these encounters can cause trouble for humans and bears alike. One method to reduce human-bear conflicts is to secure attractants like garbage and livestock feed.

While effective when implemented, this approach requires people to change their behavior, and that makes things a little more complicated.

ITHACA, N.Y. - A Cornell University-developed technology provides beekeepers, consumers and farmers with an antidote for deadly pesticides, which kill wild bees and cause beekeepers to lose around a third of their hives every year on average.

The authors, Kirill Vasin and Mikhail Eremin, contribute to the theory of electronic and structural properties of FeCr2O4 ferrimagnet. Due to the specific quantum state and the symmetry of FeO4 fragment, it has unusual electric and magnetic properties. Below TOO~150K, it lowers the symmetry with the macroscopic deformations due to the cooperative Jahn-Teller effect. The coupling between macroscopic deformation of the crystal FeCr2O4 and its inner ions shifts was revealed.

In a world first, scientists from the University of Sussex have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as 'the brain's memory centre', is vulnerable to damage and degeneration, a precursor to Alzheimer's disease.

The basis for this new take on the classification was laid in 1985, when John Long attributed a fossil tooth plate to a new species, Edaphodon eyrensis. The species was named after Lake Eyre, near which the tooth was found in 1978.

Asscoiate Professor Evgeny Popov had his doubts about the attribution. However, he had to study the fossil personally to advance his theory. The opportunity presented itself during a trip to Australia in 2010. The tooth plate was stored in a museum in Adelaide, South Australia.

Metal-organic framework compounds (MOFs) consist of inorganic and organic groups and are characterised by a large number of pores into which other molecules can be incorporated. MOFs are therefore interesting for many applications, for example for the storage of gases, but also for substance separation, sensor technology or catalysis. Some of these MOF structures react to different guest molecules by changing their structures. They are thus considered switchable.

A research group led by Takashi Saito, of the Ehime University Graduate School of Medicine, developed a 2-photon excitation light-sheet fluorescence microscope which (1) lowers phototoxicity, (2) extends the field of view, and (3) heightens spatial resolution. This microscope, when used for the observation of medaka fish, made it possible to observe the whole body of the embryo (an extended field of view) at a cellular level resolution (high spatial resolution) without affecting the growth of the fish (low phototoxicity) over a three-day span of embryonic development.

CHAPEL HILL, NC - A new study published in Nature Communications demonstrates that a consortium of bacteria designed to complement missing or underrepresented functions in the imbalanced microbiome of inflammatory bowel disease (IBD) patients, prevented and treated chronic immune-mediated colitis in humanized mouse models.

WHAT:

An environment in which family members support one another and express their feelings can reduce the effects of social deprivation on cognitive ability and development among adopted children, suggests a small study by researchers at the National Institutes of Health. In contrast, rule-driven households where family members are in conflict may increase an adopted child's chances for cognitive, behavioral and emotional difficulties.

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.

Despite their widespread use, hormonal contraceptives are known to increase the risk of breast cancer, which is the most common cause of cancer-related death among women worldwide, and also topped the list of most commonly diagnosed cancers in 2020.

East Hanover, NJ. May 28, 2021. An international team of multiple sclerosis (MS) experts has identified four under-researched areas that are critical to advancing symptom management for progressive MS, recommending interdisciplinary collaboration among scientists, clinicians, industry leaders, and those with progressive MS. Their call to action was published in Multiple Sclerosis Journal on March 15, 2021, in the article "Prioritizing progressive MS rehabilitation research: A call from the International Progressive MS Alliance" (doi: 10.1177/1352458521999970).
