Doing sports during pregnancy also gives the child the charge

Women who do sports during pregnancy are more likely to have children with high motor skills. It is suggested by a study conducted by Professor Linda May of East Carolina University.

The researchers analyzed the motor skills of the children of two groups of mothers: those who had done regular exercise during pregnancy; those that didn't. One month after giving birth, the small ones belonging to the first group moved better than those of the second. In theory, children in the first group are more likely to develop advanced motor skills in a short time. Furthermore, they are likely to become more active children than those in the second group.

The study involved 71 healthy pregnant women. Half of them did exercise about 3 days a week for 1 hour. The other half simply did very mild exercises, stretching and breathing exercises. A month after giving birth, the doctors analyzed the motor skills of the children, assigning them scores.

What kind of business does this kind of benefits have? According to the professor, the movement must be intense enough to increase the rhythm of the heartbeat. It must however be bland enough to allow you to talk during the exercise. So mothers-to-be can walk briskly, swim, ride a bike and take classes in prenatal aerobics. According to the researchers, physical exercise is likely to increase oxygen levels in the womb, stimulating fetal brain development. Or it could stimulate the release of proteins called growth factors.

Finnish genes increase the risk of obesity and diabetes

A study by the Washington University School of Medicine has identified some genetic variants specific to people of Finnish origin. According to the researchers, the genes in question could increase the risk of obesity, diabetes, hypercholesterolemia. Indirectly, they could therefore be linked to an increase in the probability of contracting cardiovascular diseases.

The study authors identified 26 genetic variations relevant for cardiovascular and metabolic health. Of these, 19 are peculiar to Finnish or Finnish origin individuals. It is calculated that they are 20 times more frequent in Finland than in the rest of Europe.

The population of the country is in fact isolated and characterized by a relatively similar genetic heritage. Finland is a country that has remained isolated for centuries, with very little immigration throughout history. Over the years, there have been at least two disastrous events that caused a collapse in the population. As a result, today's Finns all come from a limited range of genetic assets. This caused the formation of a group of diseases specific to that area, called Finnish Disease Heritage.

The disorders in question are not part of the list: they are too subtle. Yet the study showed a correlation between these "Finnish" anomalies and metabolic and cardiac disorders. The researchers would like to see if there are similar cases in other isolated populations, such as those in the South Pacific Samoa.

Can a transgender woman become fertile again?

A study by Dr. Hanna Valli-Pulaski examines the case of two young transgender women who have returned fertile. The two stopped hormone therapy in the hope of resuming sperm production. One attempt gave positive results, the other did not.

A transgender woman must follow a specific hormonal therapy that helps her to appear more feminine. However, the therapy stops the production of the spermatozoa, making the person actually sterile. On the other hand, stopping the use of drugs is a big trauma for a transgender person and doesn't always give results. The team examined the medical records of two transgender women who discontinued hormone therapy to have usable sperm samples.

He compared them with data from another transgender woman who had kept the sperm before the transition. The first patient was taking a drug called Lupron. Taken during adolescence for at least 6 months, the drug blocks puberty. The patient stopped taking it and after 5 months she started producing sperm. The samples were of good quality and usable for IVF. Unfortunately for the second patient it was more difficult.

Stopping the use of drugs causes a series of physical changes: the beard grows, the voice deepens. Going back to a more feminine aspect takes time and can be a big stress for a person. This is what happened to the second patient: the woman had been on estradiol and spironolactone for more than two years. After 4 months of interruption and still no results, the patient gave up and resumed her transition.

Pregnant women do not have to move?

Changing homes in the first three months of gestation is linked to a greater risk of premature birth. This was revealed by US research published in the Journal of Epidemiology & Community Health.

The researchers analyzed data on children born in Washington between 2007 and 2014, born of at least 18-year-old mothers. From these, they selected a sample of 30,000 women who had moved in the first three months of pregnancy. Then they compared the data with another 120,000 who had not.

The women in the first group tended to be younger, with a lower cultural level and a lower salary. He was also more likely to be unmarried and to have smoked during gestation. These are all risk factors for the fetus, linked to a greater risk of premature birth and low birth weight. As a result, the researchers took into account all these elements, so as to have the least possible "polluted" data. After eliminating the other potentially detected factors, the scientists verified whether the relocation alone had an effect on pregnancy.

A move in the first quarter is associated with 37% more chances that the child is born underweight and 42% who is born first. Furthermore, in 9.8% of the cases the children were smaller than calculated with prenatal tests.

The data concerns women from all social classes, young and old. However, researchers cannot explain the reason for this phenomenon. It is probably the fault of the stress and physical effort associated with the move.
