Arteriosclerosis: five false myths and topics

Arteriosclerosis is a pathology very unknown among the population, but it is related to almost 1 of every 2 deaths that occur annually in Spain. It is a disease of the blood vessels produced by an accumulation of fats in the wall of the arteries. Early detection and prevention are basic. In the absence of knowledge and erroneous messages, the Spanish Society of Arteriosclerosis warns about the five false myths and topics of this pathology

Arteriosclerosis is a disease of the blood vessels caused by an accumulation of fat in the wall of the arteries, which makes the blood circulate with greater difficulty and increases the risk of causing obstructions.

Arteriosclerosis: five false myths and topics

It is the cause of such serious and prevalent pathologies as myocardial infarction and cerebrovascular accidents, hence the importance of taking care of our arteries.

As it is a serious and “silent” disease, it is essential to spread its knowledge among the general population, as well as to provide adequate guidelines for its prevention.

Aware that at this time there are many misunderstandings as to what it is, how it is prevented and how arteriosclerosis is treated, professionals of the Spanish Society of Arteriosclerosis ( SEA ) has decided to clarify some basic questions about the pathology and disprove some topics.

Five erroneous messages about arteriosclerosis

1. Cholesterol is just a matter of figures

False. For a better medical assessment of cholesterol levels and the rest of the lipid profile (triglycerides, HDL-cholesterol and LDL-cholesterol) should be taken into account the different risk factors (hypertension, dyslipidemia, diabetes, sedentary lifestyle, family history of suffering heart problems, etc.).

A single figure of isolated cholesterol contributes little; the doctor should assess the vascular risk globally in patients affected by the increase in cholesterol.

2. Arteriosclerosis is a disease that affects only the elderly

False. Currently, a high percentage of the population has cardiovascular risk factors that favor the appearance of arteriosclerosis at a younger age (40-50 years)than was usual in the past. Arteriosclerosis can be detected by means of non-invasive diagnostic tests before the symptoms appear or they cause complications such as myocardial infarction.

3. Women and men should not be cared for in the same way to reduce cardiovascular diseases related to cholesterol increase

False. According to recent studies, in Spain, cardiovascular disease is responsible for 24.6% of deaths in men, and 22.5% in women; Therefore, we believe that cardiovascular care should be evaluated in the same way in both men and women from an early age.

4. It is not safe to reduce cholesterol to very low levels, it goes against cardiovascular safety

False. According to the latest scientific research, it is safe to reduce LDL-cholesterol levels to levels of less than 10 mg/dl in patients who have already suffered cardiovascular diseases, such as myocardial infarction, stroke or artery disease. lower extremities, through a pharmacological treatment without adverse effects from a cardiovascular or cerebrovascular point of view.

5. The Mediterranean diet is limited to olive oil and fish, is expensive and impossible to follow and does not reduce the risk of arteriosclerosis

False. It is important to know that the Mediterranean diet is based on a high consumption of various products: unrefined cereals, legumes, fruits, vegetables, nuts, low consumption of meat, low consumption of dairy products, as well as olive oil and fish, mainly.

The Mediterranean diet, bastion of the heart-healthy diet of many European countries, prevent cardiovascular diseases. A prevention that must be accompanied by other measures of heart-healthy lifestyles, such as maintaining a physical activity appropriate to the conditions of each person.

Baby is born the world’s first automated vitrified egg

The world’s first baby born from an automated vitrified egg, preserved by cryopreservation, came to the world in a clinic in Barcelona, Spain.

The baby was born on September 29 completely healthy, with 2.2 kilograms of weight and 46 centimeters of height, by normal delivery after 37 weeks of gestation, informed the Reproductive Medicine Service of the clinic Dexeus Mujer, whose experts managed to make this advance assisted reproduction.

Glazing is an ultra-fast cryopreservation system that reduces the time and risk of ice crystal formation, and could only be done manually up to now.

“This birth confirms the viability of this new technology, which has been on the market for only a year and is currently only incorporated by some hospitals,” explained the head of the Biology Section of the Reproductive Medicine Service of the Barcelona clinic, Montse Boada. and assisted reproduction clinics from around the world. ”

The head of the cryopreservation laboratory at the clinic, Miquel Solé, explained that “vitrification is an ultra-fast cryopreservation system that reduces the time and risk of ice crystal formation, offering a high survival rate after devitrification. of oocytes, currently around 85%. ”

The first time successful embryo cryopreservation occurred in 1983, but the introduction of oocyte cryopreservation into the clinical application only occurred in 2005.

So far, the vitrification process has always been done manually, so that the person in charge of preparing the samples and performing the different steps of vitrification until their storage in liquid nitrogen at -196ºC should be a specialist embryologist.

“It’s a job in which you have to be very strict and experienced to have a good result,” said Solé.

The novelty of this new system, called GAVI, is that it allows the exposure of the biological material, in this case, the oocytes, to the cryoprotectants to occur in an automated way and in a hermetically sealed device, avoiding the direct contact of the oocytes with the liquid nitrogen.

“The automation of the GAVI system reduces the possible risk of contamination and minimizes the small variations that may occur in manual protocols.” Reproductive Medicine of Dexeus Woman.


Denver Public Schools to Protect Immigrant Students in US

Within superintendent schools, 56% of the 91,000 students are Hispanic. Another 20% belong to other minorities.

The Denver Public Schools Superintendent announced Friday that the city’s institutions will be “safe and accepting places” for all students, including illegal immigrants.

“In light of recent local and national immigration and refugee events, the Denver Public Schools Superintendent has decided to respond to the fear and uncertainty that many of our students and families are feeling,” said Lisa Flores, a member of the board.

In addition to the idea of ​​building a wall on the Mexican border, US President Donald Trump has begun operations in several regions of the country and has threatened to reduce the transfer of resources from cities that refuse to cooperate with immigration authorities.

The Denver schools resolution emphasizes that the activities of federal immigration agents at school institutions or buses interfere with the constitutional rights of students, including the right not to be subjected to unreasonable detention or magazines, and to free public education.

“There is great strength and solidarity in being together as a community to protect the rights of our students,” said Flores.

Within superintendent schools, 56% of the 91,000 students are Hispanic. Another 20% belong to other minorities.

Since the November 2016 election, Denver’s United Parents and Young People organization has collected more than 1,000 signatures to call for schools to be declared “sanctuaries” for students and families who are at risk of deportation.

Therefore, the Denver Public Schools Superintendency will not collect information about the students’ immigration status and will not pass it on to the federal government without a court order, according to the resolution.

Increased exposure to sunlight influences high incidence of skin cancer

According to a specialist, people are now more exposed to the sun, less clothing, sun-less, and getting sunnier

More exposure to sunlight influences skin cancer to kill one person every 52 minutes in the world, said dermatologist Rodrigo Roldán Marín, head of the Oncodermatology Clinic at the Faculty of Medicine of the National Autonomous University of Mexico (UNAM) ).

The specialist explained that we are all susceptible to suffer from this disease. “We must stop believing that it is an exclusive subject of blue-eyed blond individuals. It affects black and dark people, and yet little is known about it, “he said in a statement.

According to Marin, every year more cases of skin cancer than breast, prostate, lung, and colon are recorded together, and this is influenced by a cultural change.

“Today we have unusual practices in past centuries that expose us to one of the most important environmental carcinogens: sunlight,” he said.

The expert said that today people are exposed more to the sun, with less clothing, without sunscreen and increasingly earlier.

In Mexico, he said, new cases of skin cancer are detected each year; however, there is a lack of prevention culture and this is because the disease is minimized.

“The sun causes progressive and accumulated damage and the rays received today will have repercussions two, three or four decades later, so we should promote protection habits among children and teach them how to use sunscreen.”

Marin explained that it is necessary to take into account that basal cell carcinoma is the most common cancer among humans, one in five will develop it, “and if we add that the skin is our largest organ, it is inexplicable not to take care enough”.

The expert said that much research still needs to be done about it because although the characteristics of skin cancer in white people are well known, it is necessary to sink in what happens to other characteristics.

“For example, Australia is the country with the highest incidence of melanoma because it is in the geographic region most exposed to the sun; so an Australian can generate between three and four melanomas in his life and survive, “he said.

However, Marin detailed that if a Mexican develops a melanoma, he is very likely to die due to this.

“This has to do with genetics, and although we’re not sure why, it appears that darker, though more protected, skin develops cancer in more aggressive variants when it contracts.”

The specialist said that general practitioners should be instructed to use the dermatoscope, a pocket-sized microscope, in order to detect this disease in a timely fashion.

“This would not only significantly increase the diagnostic accuracy of skin cancer variants (such as melanoma, basal cell or squamous cell carcinomas), but it would improve our reference and counter-reference system by detecting tumors in preterm infants,” he concluded.
