Interesting research topics worth reading in 2019!

Scientific research is a very serious thing in the eyes of many people, but there are always some scientists who do not go the usual way and do some very "interesting" research with big brain holes When people see these research results, they may have a bright future What interesting research findings will scientists have in the past 2019? By the end of the year, the editor has sorted out these interesting research results and shared them with you Photo source: www.pixabay.com [1] ejpc: can brushing help protect the heart? Doi: 10.1177/2047487319886018 according to a study published in the Journal of European Journal of preventive cardiology, frequent brushing of teeth is related to reducing the risk of atrial fibrillation and heart failure Previous studies have shown that poor oral hygiene can lead to bacteria in the blood and inflammation in the body Inflammation increases the risk of atrial fibrillation (irregular heart rhythm) and heart failure (impaired ability of the heart to draw blood or relax and pump blood) The study examined the link between oral hygiene and the occurrence of both In a retrospective cohort study, 161286 participants in the Korean national health insurance system aged 40-79 years were recruited without a history of atrial fibrillation or heart failure Participants underwent routine medical examinations between 2003 and 2004 Collected information about height, weight, laboratory tests, disease, lifestyle, oral health and oral health behaviors 【2】 PLoS Biol: does poverty affect gut microbes? Doi: 10.1371/journal.pbio.3000536 poverty will limit people's access to healthy food, healthy environment and "stress free" life, thus increasing their risk of multiple diseases Poverty can also harm health by reducing the homeostasis of beneficial microorganisms, according to a new article published in the journal PLoS Biology People living in low-income communities lack many factors that contribute to healthy microbial communities, such as access to fresh food, clean air and water, appropriate prenatal and post natal care, and a healthy indoor environment Scientists linked low microbial diversity to poor health, including obesity and related metabolic problems, as well as a variety of mental health and mental disorders These problems may have a disproportionate impact on the poor and exacerbate the existing health gap 【3】 J Parkinson dis: can fecal transplantation treat Parkinson's disease? Doi: 10.3233/jpd-191802 constipation is a common disease in patients with Parkinson's disease (PD) Fecal microbiome transplantation (FMT) and probiotics and probiotics are potential options for the treatment of constipation and recovery of patients with Parkinson's disease (PD) However, scientists believe that due to the lack of clinical data, more research is needed before clinical use; researchers in Journal of Parkinson's Their findings are presented in a review article in release magazine In this review, the researchers evaluated the progress of studies on the use of fecal transplantation and probiotics to restore normal intestinal microbial balance in PD patients, and highlighted the questions that still need to be answered Fecal transplantation involves the transfer of liquid filtrate feces from a health screened individual to a patient through a nasogastric or nasoduodenal tube, enema, or colonoscopy "Fecal transplantation is an interesting option to restore the homeostasis of the microbiome in PD patients," explained lead researcher Dr TEUs van Laar, head of the Department of Neurology at the University of Groningen medical center This is an attractive technique because administration is relatively simple and usually has only minor adverse reactions However, at present, there is no strict clinical trial for this treatment, and there is no systematic understanding of the optimal content of fecal transplantation, the way of administration and the long-term impact " 【4】 PLoS patch: huh? Female mosquitoes with "sex" are more likely to spread malaria! Doi: 10.1371/journal.ppat.1008063 recently, Dr Farah dahalan, from Imperial College London, Dr Mara lawniczak, from Wellcome Sanger Institute, and colleagues published a study in the journal PLoS patterns, which showed that mated female mosquitoes are more likely to transmit Plasmodium than virgin female mosquitoes The results of this study show that killing males not only inhibits mosquito population reproduction, but also reduces the malaria vector capacity of the remaining females Malaria is a mosquito borne disease caused by Plasmodium falciparum, which kills more than 400000 people and infects more than 200 million people worldwide every year The existing vector control measures depend on the continuous sensitivity of mosquitoes to various insecticides However, the resistance of mosquitoes to all four insecticides currently used has begun to increase, so new vector control strategies, including those for reproduction, are urgently needed 【5】 Sleep Med: sleep is also affected by gender, region and age? Doi: 10.1016/j.sleep.2019.07.024 according to a recent global and extensive study on sleep, the author found that people's sleep time will vary with age, geographical area and gender "Interestingly, even in people over 20, circadian rhythms change It has been known before that the sleep time of adolescence will be delayed This study shows that this delay will actually continue into adulthood In terms of region, people in Europe and North America sleep the longest, while those in Asian countries sleep the shortest, people in the Middle East sleep the latest, and people living in Oceania begin to rest the earliest The researchers said the magnitude of sleep differences caused by geographic differences was relatively small, but similar to that seen in previous studies There is no significant difference in sleep demand between cultures, but there is a significant difference in sleep time " In the study, published in the journal Sleep Medicine, the authors monitored the sleep habits of more than 17000 teenagers and young people for two weeks The monitoring was carried out with the help of the polar electro device worn by the subjects, which used accelerometers and other techniques to measure sleep Subjects agreed to use their personal data for research purposes and to process the data anonymously Photo source: www.pixabay.com [6] envir pollut: living in a green environment can reduce the risk of metabolic diseases doi: 10.1016/j.envpol.2019.113231 compared with the middle-aged and elderly people living in a less green environment, the middle-aged and elderly people living in a green community have a lower risk of metabolic syndrome This is the main conclusion of a new study by isglobal in Barcelona, which provides further evidence for the health benefits of green space Metabolic syndrome is a kind of simultaneous diseases, including obesity, hypertension, hyperglycemia and abnormal fat It is a major risk factor for noncommunicable diseases such as heart disease, diabetes or stroke So far, many studies have analyzed the relationship between environmental greening degree and various components of metabolic syndrome In this study, the researchers looked at the association with metabolic syndrome as a whole, and provided overall cardiac metabolic health and long-term indicators The study, published in the journal Environmental pollution, used data from more than 6000 adults in the UK (between the ages of 45 and 69 at the start of the study) Participants had four tests in 14 years (1997-2013) and a series of tests, including blood analysis, blood pressure and waist circumference measurements The greening degree of the house is determined by satellite image 【7】 Ann Intern Med: shock! Micro plastic detected in human feces! So the garbage you throw out may be eaten back by you! Doi: 10.7326/m19-0618 recently, a study published in the international journal Annals of internal medicine pointed out that micro plastics were detected in fecal samples of healthy volunteers In the study, eight healthy volunteers aged between 33 and 65 were asked to fill out a diet diary and collect fecal samples according to the instructions Fourier transform infrared spectroscopy (FTIR) was used to analyze the existing forms of 10 kinds of common microplastics in feces samples after chemical digestion The researchers found that all stool samples tested positive for microplastics There are an average of 20 microplastic particles per 10 grams of human feces A total of 9 kinds of plastics were detected, among which polypropylene and polyethylene terephthalate had the highest content "This small series of prospective cases shows that there are various kinds of microplastics in human feces, and no sample does not contain microplastics "Larger studies are needed, of course, to test these findings," the authors write "We urgently need to study the source, potential intestinal absorption and impact on human health of micro plastics consumed by human beings BMJ: why does your wife always ask you to do housework? Because she wants you to live a long and healthy life! Doi: 10.1136/bmj.l4570 in a new study published in BMJ journal, a multinational research team including the authors from Brest biomedical research center (BRC) in the UK has put forward clear evidence that long-term physical activity can reduce the risk of premature death of middle-aged and elderly people regardless of the intensity The study also showed that sedentary (e.g., sitting 9.5 hours or more per day, excluding sleep) was associated with an increased risk of death WHO guidelines recommend that adults aged 18 to 64 take at least 150 minutes of moderate or 75 minutes of vigorous exercise a week However, these activities, which are mainly based on self-report, are often inaccurate So researchers don't know exactly how much exercise (and how much intensity) is needed to stay healthy To further explore this issue, researchers led by Professor ULF Ekelund of the Norwegian University of Sports Sciences in Oslo analyzed observational studies that assessed physical activity and sedentary time and death ("all-cause mortality"), including the use of accelerometers, a wearable device that tracks the volume and intensity of activity while awake, to objectively measure the level of daily activity Low intensity activities include walking slowly or light tasks, such as cooking or washing dishes Moderate activities include any activities that make it difficult for you to breathe, such as walking fast 【9】 Will women age faster than men? News reading: the Victorians believed that women aged fast than men - a myth that persist today the global anti-aging market is worth at least $250 billion, which is an amazing number and growing Anti-aging therapy is considered to correct "premature aging" But what exactly does that mean? Of course, aging is aging It's a process that happens over time - at the time it should It's no surprise that the majority of consumers and audiences of this accelerated aging statement are women Men and women age at about the same rate, but the language and pictures surrounding anti-aging treatment show that women undoubtedly need to worry about aging most Any online search will show a standard photo of a young woman watching her reflection carefully, then hastily applying skin cream to her face The message is clear: it's a race against time Many companies recommend these treatments for women in their 20s Men also worry about aging, but suggestions for their skin are packaged as maintenance
