In the U.S. , a special non-toxic patch for the treatment of congenital heart defects
Bioinspired patch, with which you can quickly put biosoluble patches inside the beating heart - exactly the place of birth of holes developed in the preclinical study, researchers from Children's Hospital Boston and MIT . On it informs edition Science Translational Medicine.
When a newborn is diagnosed congenital heart defect , such as a hole in the heart , too aggressive treatments seem problematic due to the inability to quickly and safely implement the device body . Suturing takes too much time and can cause stress fragile heart tissue , and clinical patches available today are either too toxic or have a habit of losing sticky properties in the interaction with the blood or in dynamic conditions , such as heartbeat . As one of the researchers Jeffrey Karp , children with such defects are doomed to multiple surgeries to implant or replacement insoluble devices that do not grow with body tissues .
According to scientists , soluble patches with a sticky surface remain on the site of attachment even heart palpitations and high blood pressure . Study leader Pedro del Nido said that , unlike the existing surgical patches , novelty keeps sticky surface even at a constant contact with the blood in the active medium . In addition, the new patch does not contain toxic components and is completely soluble , and because nothing in the body of a foreign patients will not. Importantly, the adhesive properties of the new surgical tape are activated by ultraviolet exposure for 5 s .
Surgeons recognize that using new items reduced aggressive surgical procedures , improve patient quality of life .
FDA approved test for the diagnosis of postnatal mental retardation in children
Manage quality control over products and medicines USA (Food and Drug Administration, FDA) reported 17 January 2014 that the regulatory authority has approved diagnostic test Affymetrix CytoScan Dx Assay, which helps determine the chromosomal variations responsible for developmental delay in children or mental retardation. Based on a sample of blood test is able to analyze the complete genome of a patient at a time and to detect large and small chromosomal changes . According to the National Institutes of Health and the American Academy of Pediatrics , the various forms of intellectual development lag observed in 2-3 % of American children .
Efficacy of the test was checked by 960 samples. As a result, it was proved that the new method is significantly superior to any other similar assays .
The Office noted that the use of this test is not recommended as a standalone diagnostic tool preimplantation or prenatal testing for screening populations or genetic aberrations after birth, such as cancer. FDA also added that the study results should be interpreted only in conjunction with other clinical and diagnostic results , including the use of alternative methods , evaluation of the results of analysis of health of parents , clinical genetic evaluation , etc.
In Kemerovo -year-old girl laparoscopically removed part of the kidney
Surgeons Children's City Clinical Hospital № 5 was first operated on a child with a rare congenital defect - a full doubling of the right kidney ( uretrogidronefroz upper segment ) . Doctors were able to remove the non-functioning part of the kidney at year-old girl using modern endoscopic equipment , the press service of the hospital.
Malformation was diagnosed in girls almost immediately after birth. Due to illness the child suffered from chronic pyelonephritis , urinary tract infection . Doctors successfully removed the broken part of the kidney laparoscopically child , making only 3 punctures . 10 days after the operation has little patient was discharged home .
"The challenge was to not disrupt the blood supply to a normally functioning kidneys. We coped with their task . Operation and recovery of the child were no complications , "- said Roman Surkov , the attending physician girls .
Dimensions affect fetal heart health of the child in the future
In the new study, researchers from the Netherlands found that the lack of growth of the fetus in the I trimester of pregnancy correlated with the risk of developing cardiovascular disease in school-age child . On this question in an article published in the British Medical Journal (BMJ).
In the first 3 months . pregnancy, embryonic phase , a rapid development of the fetus , begins the formation of the heart and other vital organs . Medical researchers decided to test the effect of lack of growth at this stage of fetal development on the health of the cardiovascular system of the child .
The research professionals participated more than 1,100 school children whose mothers had regular menstrual cycles , and medical records were information on the coccyx - rump length of the fetus in the I trimester of pregnancy. Scientists have also been taken into account such factors as age, smoking , education, blood pressure , body mass index of the mother. Around the age of 6 children were tested for cardiovascular risk factors (volume of adipose tissues , body mass index , pressure, concentration of insulin and cholesterol levels in the blood) .
After analyzing the results , the experts were divided on the participants in the experiment 5 subcategories . Those who occupied the last row in the list (the smallest size of the embryo ) , to 6 years had significantly greater volume of adipose tissue , particularly in the stomach , high cholesterol and high blood pressure compared with those who had the greatest growth of the embryo. Often the child seen several negative factors simultaneously.
According to the authors , more research is needed to identify the long-term effects and biological mechanisms established relationship .
In Moscow, conducted a unique operation to remove a cyst of the pancreas
Moscow doctors conducted a unique operation , successfully removing the 12 - year-old boy pancreatic cysts . It is a rare disease that occurs in one out of 100 thousand people. Doctors commonly encountered with such a diagnosis is not more than 1-2 times a year. Operation that surgeons spent Morozov Children's Hospital, was successful , the child was discharged home in a satisfactory condition , the press service of the Moscow Department of Health .
According to the agency , the postoperative period the patient was well, and subsequent monitoring visits , the boy did not reveal any enzymatic or biochemical and clinical changes in the analyzes. Also found doctors and recurrence of the cyst.
Complexity medico Morozov Hospital operation was that the cyst is very closely adjoined to the vessels , and it was difficult to separate from their walls . In this regard, during the operation, the surgeon had to contend with constant bleeding.
"In addition , the complexity of the operation was that intraoperative decision was made to complete removal of the cyst from the abdominal cavity , because the pancreas - quite moody organ, and any of its trauma leads to violations of various enzymatic whole body " - explains the medical .
In Russia, developed a test for the Rh factor
In Ulyanovsk Nanotechnology Center developed available for research tests to perform non-invasive prenatal diagnosis of fetal . With one of them you can determine the sex of the child is in the 7th week . pregnancy and second helps already on the 10th week . determine its Rh factor . According to the head of Andrei nanocenter Redkin , test to determine the sex in the future may be useful to combat genetic diseases that are associated with this factor. The second test , which allows a safe method to determine the Rh factor , will have not only medical, but also a significant economic effect .
The test is based on analysis of venous blood. According to Andrei Redkin analogues developed in nanocenter test yet. Currently, the Rh factor can be determined only by means of puncture of the placenta , which is dangerous to the fetus. In America, a laboratory engaged in such research , but there is much more complex system , below the accuracy of the result , their technique is not used in clinics and laboratories. Tests to become available on the open market and have been included in the federal health standard , the development should receive a registration certificate Medical University .
