Scientists from Queen Mary University of London, in collaboration with the Harvard School of Public Health, concluded that vitamin D supplements do not improve bone strength or reduce the risk of fractures in children with vitamin D deficiency. The study results were published in The Lancet Diabetes & Endocrinology.

In the study, researchers instructed more than 8,000 schoolchildren aged 6-13 living in Mongolia (a region with particularly high rates of fractures and widespread vitamin D deficiency) to take vitamin D supplements for 3 years.

More than 95% of the subjects had a deficiency of this substance in their bodies at the start of the study. At the end of the intervention period, scientists updated the health status of some subjects and assessed the strength of their bones using ultrasound, gazeta.ru writes. It turned out that taking the supplements had no effect on either the bone strength of children and adolescents or the potential risk of fractures. Moreover, during a three-year experiment, the deficiency of this substance in the body was eliminated. The lack of benefit may be due to the fact that participants did not take calcium at the same time as vitamin D.

Children who were found to have rickets during screening for the study were excluded from participation because it would be unethical to offer them a placebo. The results are only relevant for children with low vitamin D levels who have not developed complications.

In Armenia, men most often turn to plastic surgeons for nose surgery. But men make up a very small percentage of the total number of applicants. Plastic surgeon Ashot Torosyan stated this in an interview with NEWS.am Medicine.

“In Armenia, only 3-5% of those seeking plastic surgery are men. They change the shape of the famous Armenian aquiline nose, make it smaller, and get a beautiful nose like Alain Delon,” Torosyan said.

The doctor found it difficult to say which type of plastic surgery is most in demand among men in the world, since recently there has been an increase in the number of gender reassignment operations, which also fall into the field of plastic surgery.

In the case of women, plastic interventions are more varied: rhinoplasty – changing the shape of the nose, face lift, blepharoplasty – eyelid correction, mammoplasty – breast augmentation, reduction, breast lift, liposuction – fat removal and abdominoplasty – abdominal tightening, etc. Recently, the number of women undergoing mammoplasty has increased significantly.

According to the surgeon, the postoperative period of the two most common operations – rhinoplasty and mammoplasty – lasts about 2 weeks.

Speaking about contraindications for mammoplasty, Torosyan noted: “Mammoplasty is contraindicated if there is a hereditary predisposition to tumor diseases or the presence of such a problem at the moment; general health is also important. There are no age restrictions.”

According to the doctor, the body-positive movement that has become widespread in the world, implying that a person should love himself for who he is and avoid aesthetic interventions as much as possible, has not led to a decrease in the number of such interventions in Armenia.

“We Armenians are very far behind in this regard. But the attitude of society has changed to some extent, we have become more tolerant of each other. We do not criticize either those who resort to interventions or those who do not,” Torosyan concluded.
