Long-term poor mood susceptible to dementia

[New crown virus likes to “make it difficult” for women] A study led by King’s College London, UK shows that women are twice as likely to have symptoms of new crown pneumonia that last for more than a month than men—but this situation will only last until around 60 years old , By then their risk levels will become closer. In addition, increasing age is also related to the increased risk of long-term new coronary pneumonia. 22% of people over 70 have the disease for 4 weeks or more, while the proportion of people aged 18 to 49 is 10%. For women in the 50 to 60 age group, these two risk factors seem to be combined: Compared with people in the 18 to 30 age group, they are 8 times more likely to develop persistent symptoms of new coronary pneumonia.

[High-sugar diet during breastfeeding can impair children’s cognition] A study in the United States showed that the intake of high-sugar beverages during breastfeeding by mothers can impair the development of children’s cognitive abilities. Researchers from the Diabetes and Obesity Project at Los Angeles Children’s Hospital have previously found that women who drink high-sugar beverages in the first few months after giving birth not only increase their risk of weight gain, but may also cause their newly born children to consume too much sugar through breast milk. The researchers further studied, asking 88 women to report the daily intake of sugary drinks such as fruit juice during the first month of breastfeeding. Two years later, they used the Infant Development Scale to assess the developmental level of their children. The results showed that the more sugar-sweetened beverages a mother consumes during lactation, the lower the child’s cognitive ability score at the age of two.

[Drinking can lead to vitamin B1 deficiency] The common consequence of long-term heavy drinking is cognitive decline and even the development of dementia, but scientists have not fully found the pathological mechanism of alcohol damage to the brain. Psychiatrists and psychologists at the Medical University of Vienna, Austria recently put forward a reasonable hypothesis: iron deposits in the brain (due to the lack of vitamin B1 due to drinking) can be regarded as a key factor in cognitive decline, and vitamin B1 supplementation can protect the brain from Affected by these deposits. Researchers believe that this study provides a new perspective for the prevention and treatment of alcohol-related nerve damage.

[Long-term poor mood susceptible to dementia] Recently, the latest research has found that long-term depression, especially among the elderly, can cause cognitive decline and further increase the risk of Alzheimer’s disease in later life. Researchers say that the accumulation of amyloid in the brain is one of the early pathological features of Alzheimer’s disease, which can begin decades before the onset of dementia. Further research found that mild depressive symptoms can increase the risk of Alzheimer’s disease by 83%.

[“Listen” to coughing to identify new coronary pneumonia] Researchers from the Massachusetts Institute of Technology in the United States said that they have invented an artificial intelligence model that can listen to the nuances of coughs between healthy people and patients with new coronary pneumonia and find asymptomatic cases of new coronary pneumonia . Specifically, this AI can identify cough differences related to 4 characteristics unique to new coronary pneumonia: muscle degeneration, vocal cord strength, mood, breathing, and lung function. The results show that the accuracy of the AI ​​model in identifying patients with new coronary pneumonia is 98.5%; the accuracy of identifying asymptomatic infections is 100%. They are currently conducting clinical tests on this AI tool, and have also submitted an application to the U.S. Food and Drug Administration (FDA), hoping to be approved as a new coronavirus screening tool.

[The new coronavirus can survive on the skin for 9 hours] A study done by scientists at Kyoto Prefectural Medical University in Japan stated that by mixing the new coronavirus and influenza A virus with culture medium or upper respiratory mucus, and applying the mixture to It can be found on the human skin obtained from the autopsy sample that the survival time of the new coronavirus is 9 hours, while the influenza A virus is 1.8 hours. The survival time of the new coronavirus on stainless steel, glass and plastic is 11 hours, which is longer than the influenza A virus. The study pointed out that after treatment with 80% ethanol, both viruses completely lose their activity within 15 seconds.

[Febuxostat for cardiovascular safety] Febuxostat and allopurinol can be used to treat gout patients and reduce urate. Recently, a team from the University of Dundee in the United Kingdom published in The Lancet the results of comparing the long-term cardiovascular safety of febuxostat and allopurinol in the treatment of gout patients. From December 2011 to January 2018, the research group recruited 6,128 patients aged 60 years and above in the United Kingdom, Denmark, and Sweden who had received allopurinol therapy and had at least another cardiovascular risk factor. . The results show that febuxostat treatment of gout is not inferior to allopurinol treatment in terms of major cardiovascular end points, and long-term use does not increase the risk of death or serious adverse events.

[High-calorie food placement is easier to remember] A Dutch study showed that compared to low-calorie foods, humans remember the location of high-calorie foods more accurately. This may be due to human evolution. A comparative experiment found that the accuracy of recording the locations of high-calorie foods by subjects exposed to food was 27% higher than that of low-calorie foods. This shows that the ability of humans to remember food space is related to food calories.
