Study: Possible biological causes for 'sudden baby -death syndrome'

A new study published in the journal “Plus” on possible biological causes of sudden baby -death syndrome. Sudden baby -death syndrome is the unexpected and unjustified death of a healthy baby, usually during sleep, and usually occurs for babies under the age of one year. These are not exactly the reasons for that tragic event. Despite the scarcity of its appearance, it is considered one of the most common causes of newborns around the world, as it occurs annually in 103 of 100,000 live births in the United States. Despite the initial success of public health campaigns that improve safe sleep environments and healthy sleeping conditions in infants in the 1990s in the United States, cases have been left like the past three decades. In the context of the study, the researchers collected tissues for a deceased baby between 2004 and 2011. The researchers investigated the 70 -babies’ brain tribes, which died during this period and tested it in search of fixed brain deformity. Serotonin receptors and researchers examined rectangular marrow in infants, who died with a sudden death syndrome of infants compared to children who died for familiar deaths. The rectangular marrow is part of the lower brain stem that partly regulates the involuntary function and the breathing system through the procedures of the serotonin neurotransmitter, is a nerve carrier that plays an important role in regulating the different physiological and psychological processes in the body. Serotonin sends signals in the brain by connecting certain proteins called receptors to the surface of neurons. By serotonin receptors, including serotonin receptors, known as 2a / c, the baby’s marrow protects the breathing problems that can occur; Especially while sleeping when the face of the baby is off or the bed with an adult. A researcher in the field of pathology in Children’s Hospital, Harvard University, Robin Heinz, the lead author of the study in statements to ‘Al Sharq’, says her team has discovered the presence of ‘nervous distortions at deceased babies compared to normal babies in serotonin 2a / c -receptors’. The researchers found these distortions in a subgroup of deceased babies, and they appear to be linked to age with more striking distortions in older children. Haynez added that some deceased babies had several distortions in the neurotransmitter system, “and it seems that these distortions endanger the risks of sudden death.” This new research supports the idea that biological disorders in some children make them vulnerable to death under certain circumstances. The researchers have previously identified a number of biological factors contributing to the death of sudden babies, including antenatal exposure to smoking and alcohol. Heinz indicated that male births are more likely to have sudden death compared to females. Princess also increases the possibility of sudden baby death. However, the new study identified the factors that work at the individual level. Genetic factors in response to the “East” question about the existence of genetic factors affecting the risks of sudden baby death, specific genes or genetic differences associated with increasing the ability to do this tragic event, Haynez said that there is “a lot of work done at the level of genetics to determine these genetic differences.” She explained that the genetic factors “influence the risk of infection with the event,” but with regard to the study, “we could not identify genes explaining the hormone hormone shown.” “The genetic variables associated with diseases known in more than 10 % of the sudden deaths of infants, including genes related to epilepsy, heart functions and genetic errors in metabolism, have been identified.” 3 Factors The researchers believe that the sudden baby’s mortality syndrome occurs when three things occur together, when the child is in a critical period of breathing heart growth in his first year, and when the child experiences external pressure, such as sleep mode on the face or constraint, and when the child has a biological disorder that makes him vulnerable to breathing problems. “The study of serotonin 2a / c receptors about 5 years ago, we began studying to expand our understanding of the serotonin hormone system in the case of baby deaths, and how this designated future can play a role in the disease,” says Heinz, who works the biological causes behind the sudden death of babies 10 years ago. Haynez noted that scientists do not currently have a way to determine the baby who is the risk of sudden death, “children of a sudden baby -death syndrome appear in good health and deformities cannot be discovered in a live baby in this neurotransmitter system. It is important to follow safe sleeping practices at all times.” The right sleeping practices include that these practices always fall asleep the child, whether sleeping in sleep or night. This is the most important step in reducing the risk of sudden death. Sleep on the side is not safe, and sleep should be avoided completely. It must be ensured that the child sleeps on a solid rank covered with a court court. While avoiding the use of soft surfaces, such as pillows, as it may increase the risk of suffocation. The bed should also be kept free of blankets, pillows, children’s games and other soft things that can hinder the child’s breathing. A blanket or a sleeping bag can be used to keep the warmth of the child without requiring a loose bed, and it is also advised to make sure the children’s bed is free from risks such as children’s beds as it may increase the risk of choking. The children’s bed must comply with safety standards and contain the cut slices properly. It is recommended that the child sleep in the same room where parents sleep, but not in the same bed. It is advised to place the children’s bed near the mother’s bed for easy access during breastfeeding while avoiding high temperature, and the child who wears suitable clothing for room temperature and keeps the room comfortable and keeps the child’s environment free from smoke, during pregnancy and after birth.
