Baby born at 21 weeks survives, against all odds
Curtis Means and his duplicate , C’Asya , were born only 21 weeks and 1 sidereal day into their gestation , meaning they were about 19 weeks previous . C’Asya did not respond to discourse and died shortly after birth , but Curtis ' vitals steady set out to improve . Even so , doctor estimated that he had only a 1 % prospect of natural selection . Over the following months , he received constant care to preserve his breathing and body temperature , and to take in adequate nutriment . He was able to number off his breathing machine at 3 months old , and he was discharged from the hospital at 9 months . After six months at home , Curtis and his family received a Guinness World Record certificate acknowledge Curtis as the most previous baby in the macrocosm to survive .

Working pig kidney is successfully hooked up to a human
With human organs in scant supply for transplant surgeries , scientists have long been working to make animal - to - human transplants safe , feasible and widely available . This class , in a watershed experimentation , doctors link a pigkidneyto a human and watched as it effectively filtered waste from the body and produced weewee . The experiment was conduct in a Einstein - numb patient role who was a file organ donor and whose family grant permission for the procedure . The team used a kidney from a genetically modified pig that lacked the gene for alpha - gal , a type of sugar that can trigger an intense immune reaction in humans . The successful experiment could point a self-aggrandising step forrad for fauna - to - homo transplanting , but many doubt remain .

Poop transplants boosted skin cancer patients' treatment
immunotherapy theoretically rally theimmune systemagainst cancer cells , but they do n’t work for all Cancer the Crab patients . Only about 40 % of patient with sophisticated melanoma , for illustration , reap long - terminal figure benefits from immunotherapy drugs . But a small study published in February in the journalSciencehints that pull off Crab patients ' gut bacteria can help advance the drugs ' effectiveness .
In the study , scientists collected stool from melanoma patient role who answer well to immunotherapy and then transplanted the affected role ' faeces — which was wedge - full of microbes — into the guts of 15 patient role who had never respond to the drugs . After the transplant , six of the 15 patient role responded to immunotherapy for the first time , demonstrate either tumour decrease or disease stabilization that hold out more than a yr . look onward , the scientist be after to investigate exactly why the poop organ transplant help these six affected role and why the other nine patient did n’t seem to benefit .

Discovery reveals potential weapon against bacterial superbugs
A study conduct in research laboratory dishes and mice suggestion at a new style to take down drug - insubordinate bacteria . This novel artillery could make existing antibiotics more effective , thus quash the need to formulate blade - raw antibiotic medication . In the study , published in June in the journalScience , scientists ran experiments withStaphylococcus aureusandPseudomonas aeruginosa , twobacteriathat show pervasive resistance to multiple drugs and social station among the leading causes of hospital - gain infections . These so - hollo poinsettia strain use a specific enzyme to harbor themselves from harm by antibiotics , so the team search for molecules that could jam the enzyme and leave the bug defenseless . The molecules the scientist identified made antibiotics two- to 15 - fold more potent against the microbe , depending on the antibiotic being used and the bacterial strain being targeted . Now , they ’ll have to see if the same strategy can work in human .

A second person is “naturally” cured of HIV
A woman now known as the Esperanza Patient was diagnose withHIV , the virus that can cause AIDS , in 2013 . But as of this twelvemonth , doctor can discover no trace of the computer virus in her eubstance . The woman receive neither a bone marrow transplant nor any drug intervention ; her immune system has on the face of it eradicate HIV from her organization on its own . This had go on once before , in a California woman named Loreen Willenberg . And although the two women are anomalousness , their cases give scientists hope of find a cure for HIV / AIDS .

Cancer vaccine shows promise in small trial
An experimental " cancer vaccinum " play by training immune cell to intimately recognize and plan of attack Crab cellular phone in the body , without harming level-headed cells . In a small trial of eight patients with advanced melanoma , the vaccinum helped forestall the patients ' tumors from develop for twelvemonth after inoculation . By the end of the four - twelvemonth follow - up full point , all eight patients were alive and six out of eight register no signaling of active disease . Two had have cancer recurrence and received additional treatment called " checkpoint encirclement , " which basically pull the brakes off of immune cells known as T cells . In compounding with the T cell - aim genus Cancer vaccine , these checkpoint blockade were highly effective . This hints that such vaccines could attend as a very important therapy , to be used in tandem with other Crab treatment , but more and larger trials are still needed to have sex for sure .

Dietary supplement restores gut bugs, helps malnourished kids grow
A newfangled dietary supplement helped malnourished children put on weight and arrive at height at a quick charge per unit than children who were given a standard " quick - to - use subsidiary food . " What made the difference ? The new supplement helped to restore the kids ' gut bacteria so they more intimately resembled the gut bacteria of goodly child .
Malnourishment leave kids ' gut microbes " stunted , " as the microbe do n’t have tolerable fuel to grow and multiply . Through thorough creature studies and a small pilot program trial with human children , a squad of scientist come up with a rule to both fork over kid the calories they need and help restitute their gut bacteria . In a larger trial , published in April inThe New England Journal of Medicine , they found that the supplement not only helped youngster arise faster but also increase the concentrations of key proteins in their blood , include those involved in bone ontogenesis and nerve and brain ontogeny .

Experimental HIV vaccine successfully stimulates rare immune cells
The first in - human trials of a unexampled HIV vaccine stirred up agitation about the experimental dig , as it showed 97 % success at stimulating a rare solidifying of resistant cells that play a key role in struggle the computer virus .
The human immunodeficiency computer virus poses a vast challenge for vaccinum developers because it mutates so quickly , but in this case , the investigator direct the pathogen using a unique approach : They designed their vaccine to target a specific subset of bacillus cells , a kind of resistant cell that create " broadly neutralizingantibodies , " protein that can latch onto a key protein on HIV and stop the computer virus from infect cells . In a trial of 48 masses , the vaccinum was dependable and induced negate antibody production in 97 % of the participants . Although this hints that the vaccine may work well , the trial did n’t like a shot test whether the vaccinum forestall HIV infection ; that will be the next step in developing .

Centenarians' gut bacteria may hint at how they survive to 100
People who live to years 100 and beyond may partly have their gut bacteria to thank , grant to a study published in July in the journalNature . In the study , researchers examined the communities of intestine bug , or microbiota , survive in 160 centenarians , who were , on ordinary , 107 years old . The researchers compare the centenarians ' gut microbiota to those of 112 multitude geezerhood 85 to 89 , and 47 the great unwashed ages 21 to 55 . The centenarian showed a trenchant gut bug " signature , " meaning specific microbes appeared in high or lower abundance than in the younger radical . In addition , they had significantly high levels of so - called secondary bile battery-acid , a fluid produce by the liver and free into the intestine . In particular , they make high concentration of the secondary bile acid isoalloLCA , which the researchers find out to have potent antimicrobial properties that may inhibit the emergence of harmful bacterium in the bowel .
More research is want to bed if and how the centenarians ' bowel bug assist them go to such advanced geezerhood and whether this knowledge could be used to boost other people ’s seniority .

HPV vaccine cuts cervical cancer rates more than 85% in UK women
A recent survey find that the human papillomavirus ( HPV ) vaccinum has reduced the number of cervical Crab case by 87 % among women in the U.K. Using cancer register data gather between 2006 and 2019 , researchers compared the cervical cancer rates among women who were vaccinated with the HPV vaccine Cervarix when they were young , between the ages of 12 and 13 , with the cervical cancer rates of women who receive the vaccine more or less later and with the pace of those who did not get the vaccinum at all .
The investigator happen that the vaccinum was most good when give to the young cohort ; women who had been vaccinated with Cervarix between the ages of 12 and 13 had 87 % fewer cases of cervical malignant neoplastic disease equate with those who were n’t vaccinate . There was a 62 % reduction in cases among cleaning lady who had been inoculate between the years of 14 and 16 , and a 34 % diminution in cases in women vaccinated between 16 and 18 , compare to the unvaccinated population .
