Selo redondo e vermelho com o texto "Isot é fake news!", criado pelo Ministério da Saúde para identificar notícias sobre saúde que são falsas.

Ministério da Saúde lança programa para evitar disseminação de fake news por WhatsApp. Você envia a notícia e recebe se ela é verdadeira ou falsa.

 

Notícias falsas, também conhecidas como fake news, não se limitam ao universo da política. Na área da saúde, tornaram-se um problema de saúde pública. Não à toa, o Ministério da Saúde criou um núcleo de monitoramento que atua nas redes sociais das 6 às 23 horas, todos os dias da semana, para identificar a origem de supostas notícias que contenham dados incorretos ou que não tenham evidências científicas.

No entanto, os canais digitais são difíceis de monitorar. Um vídeo enviado em um grupo de família ou um suposto artigo científico divulgado por um colega de trabalho se espalham rapidamente, sem que saibamos de onde vêm nem se as informações difundidas são verídicas.

 

 

Para tentar evitar os danos causados pelas fake news, o ministério criou há um mês um canal de WhatsApp para receber material suspeito. “Notamos que houve um aumento desse tipo de informação falsa há cerca de seis meses”, revela Ana Miguel, coordenadora de multimídia da assessoria de comunicação do Ministério da Saúde.

O serviço funciona assim: uma pessoa recebe material suspeito (vídeo, mensagem, link para sites, artigos etc.) e o envia para o WhatsApp do ministério (veja o número no fim da matéria), que encaminha o conteúdo para uma equipe técnica realizar o trabalho de verificação (fact-checking, expressão usada pelas agências de checagem de fatos).

Caso a notícia seja verdadeira, a assessoria do órgão devolve o material com um carimbo em que se lê: “Esta notícia é verdadeira, compartilhe!”; caso seja falsa, o conteúdo recebe o selo: “Isto é fake news. Não divulgue!”.

89% das fake news são relacionadas à credibilidade da vacina.

“O canal não é um Serviço de Atendimento ao Consumidor (SAC), não serve para tirar dúvidas, apenas para analisar conteúdo tido como suspeito”, explica Ana Miguel.

Todo material recebido é devolvido para quem o encaminhou após ser analisado e com o devido selo. A lista das fake news já avaliadas pelo ministério encontra-se no site www.saude.gov.br/fakenews.

Em um mês, tempo em que o serviço está funcionando, o ministério  já recebeu cerca de 2 mil mensagens. Destas, 310 eram fake news que foram esclarecidas. Nos demais portais e redes sociais, o órgão monitora uma média de 7 mil notícias por dia.

“89% das fake news são relacionadas à credibilidade da vacina”, revela Ana. São boatos que afirmam que as vacinas causam autismo e efeitos colaterais graves que colocam em risco a ampla cobertura vacinal do País, responsável por erradicar do território nacional doenças como poliomielite.

#20 Warning Signs of Poor Blood Circulation in Your System

Postado em

Good health depends on a lot of different factors, and a proper blood circulation is one of its main ones. The blood in our bodies is the responsible fluid to take nutrients and oxygen from one spot to another. Helping our body functioning correctly and being balanced. Whenever our blood circulation fails to deliver the proper nutrients to the specific parts of our body, that leads to a diverse range of health issues.

If these issues are left untreated, poor blood circulation can cause severe damage to our heart, brain, liver, limbs, and kidneys. There are many reasons why you may suffer from poor blood circulation. One of the most common ones if atheroscletosis. Which is also known as the hardening of the arteries. As well as peripheral artery disease (also known as PAD).

However, poor blood circulation can also be a result of a variety of health problems. Such as heart diseases, diabetes, blood clots or obesity. An excess of drinking, smoking, and also things like eating disorders or pregnancy can make you extremely vulnerable to this conditions.

If you are aware of the symptoms that show up when your blood circulation isn’t the appropriate, you will be able to control the reason behind it and find a timely treatment. Poor blood circulation can also lead to heart attacks, strokes, or even death. So make sure to check up with your doctor if you experience any of the symptoms listed below in this article. Keeping a healthy blood circulation is key to staying healthy and leading a good lifestyle!

Doctors can process a number of tests on you to find out what is causing your poor blood circulation, thus finding an appropriate solution in a timely manner. So read our article below to find out more about blood circulation.

1.Blood circulation: Swelling of lower extremities

A number of causes can produce swelling on your feet. For example, sitting or standing for a very long period of time in the same position. Or suffering from obesity, malnutrition or PMS (pre-menstrual syndrome). Among others such as high salt intake, ageing, leading a sedentary lifestyle or being pregnant. However, these listed types of swelling are only temporary and do get better within hours.

If the swelling or edema on your feet lasts for a long time, then the reason may relay on poor blood circulation. The explanation for this is that the lack of proper blood circulation make it so that the kidneys are unable to function as they should. By not being able to keep fluids in the blood vessels where they should be. The result of this is the leeching out of fluids which then settle in the surrounding tissues. This leads to swelling. In very severe cases, this poor blood circulation process can cause leg ulcers.

An easy trick to reduce swelling on your feet and legs is by laying down and raising your legs above heart level. Use some pillows or a higher chair to do so. Relax and apply cold if possible (never directly on the skin, always use towels or blankets to prevent skin burns from ice). If swelling does not reduce within a couple hours, please do consult your doctor. Blood circulation should improve once you’re laying down. But if it doesn’t, it could be a sign of poor blood circulation and needs to be diagnosed

If you also get swelling in other extremities or if your swelling includes discolouring or bruising under your skin make sure to inform your physician about that. Take pictures and write down when it happened and how it happened, if anything triggered it.

2.Blood circulation: Numbness of hands and feet

Numbness of hands and feet can be a consequence of numerous factors. But it can also be a sign of poor blood circulation. Numbness is usually felt in two different ways. The first one being a slight tingling on your extremities. This is reported to feel like little insects or ants walking over your skin. Just like when your hands or feet fall asleep and start waking up again.

The second symptom being what is usually called numbness. A feeling of numbness is when you stop feeling your extremities the way you usually do. When poor blood circulation comes into play, you will have this feeling that your hands and feet are swollen and cannot really feel what you touch. Like if your extremities had fallen asleep and couldn’t really wake up.

In this case, you need to be careful not to hurt yourself when doing normal activities as you won’t have full sensitivity in your hands and feet. Whenever your blood circulation is not at its best, there are several things you can do to help your extremities.

First of all, keep your hands and feet warm. Move them around, clap your hands, walk often. Don’t let your blood circulation get the best of you! If you have to sit or stand in the same position for long at work, make sure to take small breaks. Move around and stretch to help your blood circulation get back to normal. This will also help you get a little extra fitness!

If you do feel like your hands or feet are often feeling numb or tingling, you may want to check with your doctor. Blood circulation issues can be solved easily if treated on time. Just give a quick call to your local doctor if you have any of these symptoms.

3.Blood circulation: Cold hands and feet

Similarly to the above, having cold hands and feet is a symptom of bad blood circulation. It usually goes hand in hand with numbness and tingling, but not always. You may experience them together or separately.

Our blood is what maintains our body temperature. Thus, when having poor blood circulation, your extremities may suffer from a loss of temperature. Your hands and feet are the furthest parts of your body, so it’s normal that they suffer first. Including your fingers and toes. Additionally, blood circulation is what takes the oxygen to the cells around the body. When oxygen levels drop in your cells, this can lower the body’s temperature.

If you feel like your hands and feet are getting too cold, make sure to rub them. Try clapping your hands, jumping, massaging your hands and feet. Moving around will help getting your blood circulation going. However, poor blood circulation is not the only thing that could cause this symptom. A peripheral neuropathy, Raynaud’s syndrome, or even an underactive thyroid are common causes. Make sure to cover your extremities if it is cold outside and to use loosen clothes. This will help with your blood circulation. Additionally, make sure to use the correct size of shoes to tackle the problem on the feet. High heels or open shoes may cause blood circulation issues if used with the wrong size or temperature.

Whatever the cause, it is very important to tackle the problem correctly. Your doctor will be able to diagnose what causes your cold hands and feet. If related to blood circulation, you will get proper treatment. Make sure to bring all your current medications with you and to list any other symptoms that you may feel. Same applies to any other causes whenever needed.

4.Blood circulation: Persistent tiredness and fatigue

Tiredness is a typical symptom of physical effort and can also be linked to numerous drugs. Nonetheless, when consistently feeling weakness and fatigue, the reason may lay on poor blood circulation to various body parts.

Struggling organs will fight to make sure they continue functioning correctly. It even influences the way muscles work. As they are not getting enough nutrients and oxygen.

Alongside weariness and tiredness, a few people may significantly experience the ill effects of shortness of breath, absence of stamina and sore muscles. These are few of the associated symptoms of poor blood circulation related to your system. More reasons for tiredness include excessive drinking (alcohol abuse), uncontrolled intake of caffeine, lack of quality sleep, inactivity, bad dietary patterns, anxiety, grief, depression and stress.

All in all, having proper blood circulation means having good health. As soon as blood circulation is affected, our body will show symptoms to alert us. If you feel like you have any of the ones listed in this article, you really want to contact your doctor. Blood carries the oxygen around our body, and a lack of oxygen in our cells and brain can cause critical issues in the long-term. When caught early enough, it can be cured and controlled without further issues.

However, tiredness and fatigue may also be the symptoms of a list of other diseases. This is also why it is important to always keep your doctor in the loop of what happens within your body. Either by poor blood circulation or any other reason, it is important that you feel energetic and ready to conquer the day at any given time! If that is not how you feel, you definitely need to visit your doctor of choice to check your blood circulation.

5.Blood circulation: Slow healing and weak immune system

A slow blood circulation (also called circulatory system) will directly affect your immune system and general health. Because of poor blood circulation, your body is not receiving the vitamins and minerals that it needs to fight off diseases and infections. As these are not distributed in a timely manner or even in proper amounts. This directly affects the capacity of your body to recognise, diagnose, and fight off pathogens.

Whenever your immune system is weak, you will notice that your body suffers more often from common diseases or takes you longer to heal. You may also notice that you get bruised easily, this is due to blood thinning. Or even that small wounds hurt more and take very long to heal or scar. Your gums may bleed as well as your nose.

To enhance your blood circulation and get your immune system back to work, make sure to incorporate exercise in your every day schedule. Even just 20 minutes of walking, five to seven times a week can make a real difference to your blood circulation and immune system. Additionally, keep a balanced diet so that your body gets all the right nutrients. Make sure that your dishes are colourful and incorporate plenty of leafy greens, veggies, fruits, and proteins. Avoid sugars and processed foods, as well as carbonated sodas.

If after doing all these things you still feel weak and not healing properly, it is necessary that your refer your problems to your doctor. The physician will be able to diagnose whether your issues are related to poor blood circulation or to any other cause. Whatever the reason, make sure to follow the steps your doctor lays down for you and keep a balanced lifestyle with exercise and proper nutrition.

6.Blood circulation: Varicose veins

Varicose veins developing in the legs can be a side effect and also a reason for poor blood circulation. Because of an incorrect blood circulation system, there is a pressure buildup in your legs. This leads to varicose veins just under the first layer of the skin. Veins then become extremely visible, twisted, and swollen.

Varicose veins have a tendency to show up on the lower part of the legs and cause itchiness, irritation, pain, restlessness, heaviness and burning sensations. The presence of protruding veins is obviously a beauty concern for those suffering it and having to show off their legs at work or social events. However, varicose veins are not only caused by poor blood circulation. They are also common symptoms of hereditary diseases, obesity, hormonal changes, jobs that require standing still, the use of birth control pills, and even constipation.

On the off chance that you have varicose veins, it is extremely important to wear pressure stockings to allow for appropriate blood circulation to occur. Additionally, counsel your specialist to decide the correct reason and treatment for your varicose veins. Varicose veins can be treated with non-invasive procedures such as massages, use of compression stockings, and laser. But can also be reduced with injections and surgery.

Additional Information:

Making a few changes in your lifestyle and nutrition will help control, reduce, and prevent the appearance of varicose veins. If the reason behind them is indeed poor blood circulation, your doctor will be able to prescribe proper medication. As well as providing important advises to get your circulatory system in motion again! Always make sure to bring a list of your medications when visiting the doctor and listing any other symptoms you may be suffering from. This will help with the diagnose and get you back on your feet in a timely manner!

7.Blood circulation: Hair loss

Balding with no apparent reason is an unmistakable sign that blood isn’t getting pumped appropriately around your system. The moment your scalp is not receiving the appropriate amount of essential nutrients, you will feel your hair becoming thin and dry. Thus falling out at a higher rate than usual.

When the hair loss issue is related to poor blood circulation, the use of specific shampoos is unnecessary. Instead, it is very important to activate the follicles in your scalp. In order to do so, make sure to wash your hair with your head downwards and massage throughout. This will activate the cells of your scalp and bring more blood circulation to it. Another way to diagnose blood circulation issues is to check your skin and nails. If you get brittle and weak nails, as well as dry skin and hair loss, you are not getting the proper nutrients. Which is usually related to poor blood circulation.

Even though hair loss is usually encountered in men, women can also suffer from it when it comes from poor blood circulation. Other factors causing baldness are stress, excessive smoking, aging, hormonal imbalance, nutritional deficiencies, thyroids, anemia, chronic illnesses, and genetic factors among many.

If you notice that your hair is falling off faster than usual, it is getting thinner and the ends are split, check your skin and nails. If they’re dry and brittle, then get an appointment with your doctor. After running a few tests you will be able to have a proper diagnose of the causes for your hair loss and start treatment straight away. Make sure to tell your doctor if you noticed any other symptoms and bring with you your most recent blood tests and list of current medication as to avoid any interactions.

8.Blood circulation: Erectile dysfunction

Blood is the reason why most of our organs work the way they do. When there is poor blood circulation, many things will stop working or will work from time to time. This includes the reproductive organs. A poor blood circulation can cause erectile dysfunction in men. This issue is represented by consistent problems in sustaining and even achieving an erection even though the subject feels aroused.

Erectile dysfunction (also known as ED) is also frequently associated with atherosclerosis. This is another very important reason to leave any embarrassment behind and to contact your doctor as soon as this becomes a recurrent problem. Due to erectile dysfunction being caused by physical and not emotional issues, it can be treated if diagnosed correctly.

Whenever visiting your doctor, make sure to take with you not only a list of your current medications and illnesses. But also a detailed list of the dates and times erectile dysfunction has happened to you. This will help the doctor diagnose the reasons behind erectile dysfunction and help you correct it as soon as possible. Once the issue is solved, either blood circulation or atherosclerosis, you will be able to achieve and sustain proper erections, thus returning to a satisfactory sexual life with your partner.

Do not feel ashamed or afraid to talk about this. Many men suffer from erectile dysfunction and the only way to solve the issue is talking to a physician. Keeping it a secret will only add to your stress and anxiety and make the problem not only physical but also psychological. Leading to a more complicated treatment. Make sure to talk about it with your physician and also with your partner as to get the proper support and treatment, you will soon be happy again!

9.Blood circulation: Cyanosis or skin discolouring

On the off chance that your skin or lips turn blue, it unmistakably shows low blood oxygen levels due to poor blood circulation. This issue is otherwise called cyanosis or skin discolouring.

When your blood circulation is normal, your skin will look its natural shade and organs will look either pink or red. However, whenever your blood circulation levels drop, your skin and organs will turn of a greyish color. Some part of your body will turn blue instead, similar to a bruising color. These parts are: fingers, toes, nails, eyes, gums, and lips.

Blue skin is also an early sign of heart disease in babies. It is very important that if you ever get or see someone getting blue or extremely discoloured skin, that you call a doctor or emergency services. Cyanosis can be the indication of something going extremely wrong with your heart and blood circulation so it needs to be treated as soon as possible.

Family history, current medications, and a list of all the symptoms that you have felt is what the doctor needs to diagnose you and treat you correctly. Make sure to take them with you when you attend your next appointment or the emergency room at your nearest hospital. Congenital heart diseases are a major factor for skin discolouring so it is very important to have the above with you when seeing a doctor. Take a friend or relative with you in case you need to be administered medication that may make you dizzy or hospitalised for the time being. Don’t worry, this can be treated, but it is important to catch it on time. Do not wait for the next time it happens, go as soon as occurs the first time. Better safe than sorry, even more when talking blood circulation!

10.Blood circulation: Heaviness in the chest

Our heart is the main and most important organ in your body. Its function is to pump blood around, thus being the manager of blood circulation as we know it.But in order to pump blood correctly, it also needs to receive blood correctly. If your arteries are not bringing enough blood back to your heart, it will cause heaviness and tightness.

The pain will not be constant, it will come and go. This pain is usually known as andina pectoris or angina. However, pain and heaviness in your chest can also be a symptom of atherosclerosis in your arteries. In addition, this same pain can also represent heartburn, muscle spasms, acidity, stomach ulcers, indigestion, or upper respiratory infections.

Because of its nature, it is important that chest pain is treated as soon as possible. Either one of the reasons above can lead to serious heart damage as well as many other organs. Please make sure to check with your physician as soon as possible.

11. Reduced cognitive function

When you think of blood, you do not always think of the brain. The first thing that generally comes to mind is the heart along with its accompanying veins and arteries. This is correct, and technically blood does not go into the brain. There is even something called the Blood-Brain Barrier which is specifically designed to keep blood out of the brain.

While blood does not enter the brain, the brain does need the things that get carried by the blood. This includes oxygen and nutrients to name but a few. Therefore, the brain, like every other part of the body, requires sufficient blood flow if it is to operate correctly. When this blood flow has been decreased, then there will certainly be problems.

Many symptoms of poor circulation are a lot more intuitive than reduced cognitive function. But, if a person has problems remembering things, or possibly they feel a bit mentally foggy, then they could be suffering from reduced or poor circulation. A diagnosis of this kind can only be made if the person displays other symptoms, but it is completely advisable to take it very seriously if the cognitive function is impaired.

A person cannot survive without their brain and if poor circulation is left untreated, the brain will not only suffer in the short-term. If the brain is left without proper blood flow for too long, then the cells will start to die. Unlike other cells in your body, brain cells don’t regenerate properly. Once they have been damaged, the chances of them recovering are incredibly slim. Your mother may have told you that you only get one set of eyes, but you also get one brain.

12. Digestive irregularities

This is another system that one doesn’t usually associate with blood flow. When you think of your digestive system as a whole, you think of food and the waste matter that is created once this food has been broken down. But, consider for a second how this system works. It is a very active system that requires a reliable source of blood, and it needs this blood constantly. No part of the digestive system can be left without blood for any period.

If there is a case where circulation is reduced, then there will be disruptions to digestion. These disruptions can be of many different kinds as the digestive system is quite complex and is made up of many different parts. The noticeable digestive problem that could result from poor circulation is a pain in the abdomen. The abdomen houses the digestive system, so clearly this is the area that would hurt if something goes amiss. This pain may be localized, or it could be a pain that spreads through the general area.

The other problem which could arise is related to the stool. You can tell a lot about the health of a person by looking at their stool. In the case of poor circulation, there is a multitude of things that could go wrong with one’s stool. A person could experience very uncomfortable bouts of diarrhea, or they could even be very constipated.

The type of issue that one is having with their stool is almost irrelevant. The point is, if there has been a drastic change in a person’s bowel movements, then they could very well be suffering from poor circulation.

13. Systemic cramping and pain

There is not a single person on this planet who has not experienced muscle pain at some point or other. There is muscle pain that results from exercise. Then there is the pain that accompanies an injury. Most people also know what it is like to have stiff joints. Granted, this is generally more felt by the elderly, but on the whole, people are quite aware of the concept. The same can be said for cramping. People sleep in awkward positions and pull their backs out all the time. The one thing that all these types of aches and pains have in common is that the people suffering from them can generally pinpoint the root of the problem.

They know that they may have pushed their workout too far, or possibly the sat in an awkward position for too long. If, however, a person has muscle pain or joint cramping and they have no clue why they are feeling that way, then the problem could be poor circulation.

The concept is quite simple, and muscles need blood to function. They need oxygen, and they need nutrients. If they do not get these things, then they will stop working properly. If this wasn’t bad enough, not only will the muscles stop working, they will also start to hurt. This pain will generally result from the stiffness and cramping that will arise when the muscles do not get enough blood.

There will also be pain that will be associated with the reheating of the hands and feet which have become cold due to inadequate blood flow. This pain will be more throbbing than stabbing, but it will be pain none the less.

14. Ulcers on the legs

This condition is not one that is very well known. People may know about ulcers when they think of their mouths as mouth ulcers are relatively common. But, it is possible to get ulcers elsewhere on one’s body. In particular, these ulcers can appear on one’s legs. First, let us have a look at what would happen to the blood in the legs if circulation was decreased.

When blood circulation has been impaired or reduced, what happens is that the blood starts pooling in the veins. This does not necessarily occur in the arteries as the blood here is pumping out the heart and isn’t as affected by gravity. But, the blood in the veins has to try and work against gravity to make its way back up to the heart.

When the circulatory system has been impaired then this blood pool, especially in the legs, which then creates a hospitable environment for ulcers. It is more likely for these to develop on one’s legs, but it is possible for them to appear in other parts of the body. Another reason why a person with bad circulation is prone to ulcers is that of how bad circulation affects a person immune system.

If blood is not flowing correctly, then a person’s immune system is compromised. When this happens, then it will take longer for them to heal which is another thing that will contribute to the development of ulcers. This symptom of poor circulation is one of the more visible ones as an ulcer on the legs or feet of a person is incredibly hard to miss. There are also not many other conditions which will result in this kind of skin condition.

15. Inability to perform strenuous tasks

The secret to living a healthy and happy life is no real secret. There is no mystery here, and there is no real debate. There may be people out there who would want to argue the finer points, points like whether it is healthier to be vegetarian or whether humans need meat to survive. These points will be discussed until the end of the earth. But at the core of each argument is that to be healthy a person needs to do a few simple things.

They need to eat healthy food that is not overly processed, and that is not loaded with chemicals. Added to this diet is exercise. A person who is not exercising is a person who is certainly not healthy. Now, this is all well and good, but what about the people who physically cannot exercise.

Put aside fitness levels for a moment and think about what it must be like to not even be able to walk up a flight of stairs without getting severely out of breath. Or trying to lift something heavy and not be able to move it an inch. This is a very real reality for people with poor circulation. They may not even know that this is why they are unable to perform specific physical tasks. They might think that they are unfit and that they need to try harder.

The reason why people with bad circulation are less physically capable is that their muscles are not getting enough blood and not at the correct speed. Their heart is also taking the strain as it is forced to pump harder to try to get the blood to where it needs to go.

 

16. Unexplained weight loss

These days everyone is obsessed with their weight. People go to the gyms on mass. They spend thousands on diet products and are always on the lookout for the next best thing that will make them thin without having to put in too much effort. This is the society we live in. The thinner, the better. It is for this reason, that if a person suddenly loses weight, they would not blink an eye.

They would more likely be thanking their lucky stars rather than sitting back and trying to figure out what is happening. But, and there is no argument here if a person loses weight and they can find no explanation for it they should not just brush it under the rug. This person needs to take a moment to try and figure out what has changed in their lifestyle. Are they more stressed than usual or possibly they have changed their diet? Maybe they have started a new medication?

If they can find absolutely no reason for this weight loss and they have a few of the other symptoms on this list, then the culprit could be poor blood circulation. Poor circulation does not necessarily affect one’s weight directly, and it is more of a secondary consequence. When a person’s blood is not getting appropriately circulated, they are more inclined to have a decreased appetite, after an extended enough period, this will lead to weight loss. There is also the case of malabsorption. If the digestive system is not getting the correct blood flow, then it does not operate properly. Food is not broken down and absorbed correctly, also leading to weight loss over time.

17. High blood pressure

Blood pressure is a bit of an odd physiological value. It is not one that is widely understood by those who do not work in the medical field. People know about their heart. They know that it beats and on the whole, they can find their pulse if they need to. Barring this, they can feel their heartbeat if they are paying enough attention. But heart rate is only one part of the equation. There is the speed at which the heart pumps blood around the body, and then there is the actual pressure that is created when the heart pumps this blood.

It is almost counter intuitive, but when the body is experiencing poor circulation, a person will have increased blood pressure. This is because the heart has to work harder to pump blood throughout the body. If blood is pooling in one’s limbs and muscles then when the heart tries to beat as normal, it is trying to fit more blood into a space that already has blood.

On the surface, a slight increase in blood pressure may not seem that dangerous. This is only somewhat true. The body is designed to handle periods of high blood pressure. The heart and blood vessels will not be immediately affected if blood pressure increases. There are times when it is normal to have elevated blood pressure. The problem here would involve the timeframe.

High blood pressure in the short-term will not necessarily cause long-term damage. But, if this high blood pressure persists for too long, then the body will start taking the strain. This damage will not only be limited to the heart and blood vessels, but even organs like the kidneys will begin to falter if blood pressure remains high for too long.

18. A decrease in libido

Sex is very much a part of life. It is arguably one of the most critical aspects of the human experience. There are some who may even argue that it controls the world. If this is, in fact, the case, then it would be because sex is a huge motivator for many people. This number is not one that can be tested, but it is safe to say that a lot of us, maybe even all of us, make a lot of our decisions with sex in mind. Considering how important sex is in our lives, it is odd that we are so reluctant to talk about it.

While we may have made quite a bit of progress in this arena over the last couple of years, we are not almost nearly where we need to be. We need to be able to talk about sex not only for our mental health but our physical health as well. The reason for this is because sex is important as it is quite a reliable indicator of one’s overall health.

When using this as a health indicator, doctors will look at not only the reproductive organs themselves but also at a person libido. Libido is made up of a couple of components. There are quite a few hormones involved which are made in the brain and the organs themselves, and then there are the organs which contribute in their way to one’s libido. When it comes to poor circulation, if these organs do not get the correct supply of blood then they will not work in the way that they should.

This applies to both men and women and will manifest itself in a decreased libido. There will also be other dysfunctions in this area including irregular menstrual cycles for women and decreased fertility and functionality in men.

19. Dark rings underneath your eyes

Sleep is incredibly important. A person can go longer without food then they can without sleep. When a person sleeps, their body recharges, and it heals. If a person does not get enough sleep, the effects are incredibly visible. Symptoms of sleep deprivation range from mood disturbances to a decreased immune system. There is also the appearance of little bags and dark rings underneath the eyes.

While these bags and rings may not be attractive, they are temporary. But, if you have dark rings underneath your eyes that won’t go away even though you are getting the correct amount of sleep. Then there may be other factors that should be considered. One of these being bad circulation. There are certain items on this list which are more secondary consequences of poor circulation as opposed to a direct result.

When it comes to dark rings underneath the eyes, these appear because blood is not moving the way it should. Instead, it is pooling in that area and not being circulated by the natural mechanisms in place. As mentioned, there are other causes for these dark rings other than poor circulation. But, there is a very easy way to check whether circulation is the culprit.

The way to do this is to press down on the rings while looking in the mirror. If the rings subtly clear up for a few seconds and then darken up again, then the problem is poor circulation. This little at home test should tell you whether you are having circulation issues, but it will not tell you the extent of the problem. A doctor can only do this after further testing.

20. Brittle nails

When one thinks of their health, they do not generally look to their nails as indicators. Many people do not even look after their nails, so they wouldn’t even actually know if something is wrong with them. Sure, smokers may look at the discoloration and think that maybe their health is taking a beating, but this isn’t even an internal consequence and is only due to the nicotine in cigarettes.

While nails may not be the gold standard when it comes to testing one’s health, they can be good indicators if you know what to look for. The first thing that needs to be considered is the quality of the nail. Are the strong or are they brittle? Do they chip and break very easily or are they thick and hard to cut? If the nails are brittle, then there could be a circulation problem that exists. The reason for this is that nails, like every other part of the body, needs nutrients to grow.

If circulation is weak, then these areas will not be getting enough nutrients and they will, therefore, be weak and will not grow properly. Another way that nails can indicate the quality of circulation is by looking at the nail beds themselves. If you press down on them until they turn white and then release, look at how long it takes for them to go pink again. If this seems like it is taking too long, then there could be a prevailing circulatory problem.

When it comes too poor circulation, there are many symptoms which can be sought out simply because bad circulation will affect the entire body. By looking at one’s nails, you will not be able to make a full diagnosis, but it will give you a pretty good idea on the state of one’s blood circulation.

How to Improve Blood Circulation

• Add physical exercise to your daily routine.

• Stress can be one of the affecting causes of poor blood circulation. Practice meditation, mindfulness, and yoga to control your stress levels.

• Massage your body using warm olive oil and some drops of rosemary essential oil. Use it on your extremities such as hands, fingers, feet, and toes. As well as legs and arms.

• Try contrast hydrotherapy (jumping from hot to icy water and viceversa) to improve your blood circulation.

• Posture is a leading factor to blood circulation, either good or bad. Talk to a professional to make sure that you sit, walk, and stand properly.

• Caffeine is also not good for blood circulation as it causes anxiety. Change it for green tea or herbal teas in general.

• Alcohol intake must be reduced to a minimum.

• Smoking is bad either actively or passively, so we advise to quit smoking and to stay away from secondhand smoke.

• Add nuts, black pepper, cayenne pepper, seeds, onion, garlic, and ginger to your diet to boost your metabolism and blood circulation.

• Proper shoes are key to keep your legs and feet healthy and to help with blood circulation.

Confira 10 dicas para você orientar seu paciente com conjuntivite

 

Muitos pacientes com doenças virais, como o resfriado comum ou as conjuntivites virais, saem do consultório frustrados por não prescrevermos tratamentos efetivos contra estas infecções. Na verdade muitos queriam a receita de um antibiótico ou uma solução imediata. No entanto, vale ressaltar que essas doenças são virais e não podem ser tratadas com antibióticos.

São autolimitadas, duram em geral de sete a 10 dias e não há medicações que solucionem imediatamente essas infecções. O que precisamos lembrar constantemente é que na conjuntivite viral, por exemplo, o mais importante são as orientações para evitar o contágio e para o alívio sintomático.

As orientações fazem parte do tratamento e acompanhamento desses pacientes. Quais seriam elas?

  1. Lavar as mãos constantemente e não coçar os olhos;
  2. Não compartilhar toalhas, roupas de cama, etc;
  3. Desinfectar superfícies e itens compartilhados com álcool 70% para evitar transmissão;
  4. Orientar ao paciente que a conjuntivite viral é uma condição autolimitada, podendo haver piora do quadro nos primeiros quatro a sete dias. O quadro pode se arrastar caso o paciente tenha envolvimento corneano;
  5. Evitar contato com pacientes imunodeprimidos, crianças e gestantes;
  6. Restringir atividades para pacientes com exposição significativa a outros indivíduos durante o quadro (atestado);
  7. Compressas geladas aliviam os sintomas;
  8. O uso de lágrimas artificiais, preferencialmente sem conservantes, também pode aliviar os sintomas;
  9. Suspender o uso de lentes de contato até a resolução dos sintomas;
  10. Não existe benefício no uso de antibióticos ou corticoides na conjuntivite viral aguda. Os corticoides têm indicações específicas na fase tardia da doença;

#Colesterol nos ovos associado a doenças cardíacas e morte

Postado em Atualizado em

Fonte de imagem: MyFitness

Um estudo recente revelou que o risco de doenças cardíacas e morte aumenta com o número de ovos consumidos pelo indivíduo.

O estudo foi conduzido por uma equipa de investigadores da Faculdade de Ciências da Saúde Zuckerberg da Universidade de Massachusetts Lowell, EUA e contou com a participação de 29.615 adultos norte-americanos que foram acompanhados durante 31 anos.

Foi apurado que por 300 miligramas adicionais de colesterol consumido, para além de uma base de 300 miligramas diários, foi associado um aumento de 17% no risco de doenças cardiovasculares e de 18% no risco de morte.

O consumo de ovos tem vindo a aumentar nos EUA e atualmente não existem diretrizes com recomendações sobre a quantidade de ovos que cada indivíduo deve consumir diariamente. Os especialistas em nutrição tinham começado a considerar que as gorduras saturadas eram o fator que causava níveis elevados de colesterol e não os ovos, disse Katherine Tucker, coautora do estudo.

Antes de 2015, as recomendações ditavam, porém, que cada indivíduo consumisse no máximo 300 miligramas de colesterol por dia. Um ovo grande contém quase 200 miligramas de colesterol, o que corresponde à quantidade encontrada num bife com 225 gramas de peso.

O queijo, os produtos láteos gordos e as carnes processadas como as salsichas também contêm níveis elevados de colesterol.

Consumir vários ovos por semana é, segundo Katherine Tucker, razoável, pois estes contêm nutrientes que são benéficos para a saúde ocular e óssea. “Mas recomendo que as pessoas evitem comer omeletes com três ovos todos os dias. A nutrição tem tudo a ver com moderação e equilíbrio”, comentou a investigadora.

Finalmente, os resultados do estudo indicaram que o regime de exercício físico e qualidade geral da alimentação, incluindo a quantidade e tipo de gordura consumida pelos participantes no estudo, não alterou a ligação entre o colesterol na alimentação e o risco de doenças cardiovasculares e morte.

#Is HIV Immunotherapy the New HIV Cure?

Postado em

Using HIV immunotherapy, scientists from the University of Pittsburgh Graduate School of Public Health have made an interesting development in the race for a cure. While “cure” is a strong and coveted word in the field of medicine, what they’ve discovered comes pretty close.

So what is all the hype surrounding this revolutionary immunotherapy and how did scientists discover it?

Let’s take a look.

This powerful all-in-one immunotherapy is designed to kick HIV out of hiding from the body’s DNA within the immune system. Not only does it find it – it kills it. The “kick and kill” strategy has been around for awhile now, and this promising therapy is the highest on the list because it not only brings the HIV cells out of hiding, but it also recruits healthy cells to help kill the virus.

In the laboratory, scientists used existing cells from HIV patients to find the actual cells that are harboring the HIV.

HIV virus

Antiretroviral Therapy (ART)

Antiretroviral therapy (ART) is the first in line for current treatment. It controls HIV so well that it practically keeps the virus completely hidden in the blood. While this is great because it lowers the risk of contagion, the HIV is still very much there. It’s just in a dormant state, hiding within T helper cells of the human body.

Also, there is a long list of side effects from ART.

These include gastrointestinal and cardiovascular complications, bleeding, and even insulin resistance. The therapy also potentially compromises bone density and health of the liver.

But with the new immunotherapy on the horizon, ART may become obsolete.

So How Does HIV Immunotherapy Work?

The immune system is very busy controlling a virus that is prevalent in over 95% of HIV patients. Scientists call this Cytomegalovirus (CMV). Scientists realized that maybe they could study the cells that fight CMV and see if they could activate CMV- specific T helper cells.

Along with targeting the discovery of these T helper cells, scientist Mailliard from the University of Pittsburgh also wanted to isolate dendritic cells.

Dendritic cells are critical in assigning roles to its other immune counterparts and thus, are essential for HIV immunotherapies.

By using antigen-presenting type 1-polarized, monocyte-derived dendritic cells (MDC1), we are able to find and activate CMV-specific T helper cells.

And once we activated them, the true experiment began.

According to Mailliard, “Without adding any other drug or therapy, MDC1 were then able to recruit killer T cells to eliminate the virally infected cells. With just MDC1, we achieved both kick and kill. To our knowledge, this is the first study to program dendritic cells to incorporate CMV to get the kick, and also to get the kill.”

The University of Pittsburgh is now pursuing funding for real clinical trials to begin testing in humans.

What Could This Mean for the Field of HIV Medicine?

It means that these findings may lead to an impactful vaccine; one that would allow people living with HIV to stop taking ART every day.

It also opens the door for a cure, as opposed to just a better quality of life that ART gives. The retrovirus therapy allows HIV patients to live a more peaceful life, without symptoms constantly flaring up – it leaves the virus virtually quiet within the blood.

But the immunotherapy utilizing MDC1 and T helper cells actually kills HIV cells. With more research and human clinical trials, this could certainly lead to actually fighting the powerful disease and destroying HIV altogether.

#Formam-se novos neurónios até depois dos 90 anos de idade

Postado em Atualizado em

A formação de novos neurónios, conhecida como neurogénese, ocorre até depois dos 90 anos e em cérebros com défice cognitivo e até com doença de Alzheimer, demonstrou um novo estudo.

Conduzido por uma equipa de investigadores liderada por Orly Lazarov, docente de anatomia e biologia celular na Faculdade de Medicina da Universidade de Chicago, EUA, o estudo teve como base a análise de tecidos de 18 cérebros de pessoas falecidas com idades entre os 79 e os 99 anos. A média de idades dos cérebros era de 90,6 anos.

A equipa procurou células estaminas neurais e neurónios recém-desenvolvidos nos tecidos. Como resultado, foram detetadas, em média, 2.000 células estaminas neurais em cada cérebro. Foram ainda identificados, em média, 150.000 neurónios em desenvolvimento em cada cérebro analisado.

A análise de um subgrupo dos neurónios em desenvolvimento revelou que o número de neurónios em desenvolvimento era significativamente inferior nos cérebros de pessoas com défice cognitivo e com doença de Alzheimer, em relação às que tinham uma função cognitiva normal.

Contudo, “o interessante é que observámos alguns neurónios novos nos cérebros de pessoas com a doença de Alzheimer e com incapacidade cognitiva”, disse Orly Lazarov.

A investigadora indicou ainda que as pessoas que tinham tido melhores pontuações em medições da função cognitiva possuíam uma maior quantidade de novos neurónios em desenvolvimento, em relação às que tinham tido piores pontuações, independentemente dos níveis de patologia cerebral.

Orly Lazarov considera que os níveis mais reduzidos de neurogénese no hipocampo estarão associados a sintomas de declínio cognitivo e de menor plasticidade sináptica, e não com o grau de patologia cerebral.

A ideia de continuarem a formar-se novos neurónios após a meia-idade, sem falar após a adolescência, é controversa pois estudos anteriores ofereceram resultados contraditórios.

A autora está muito entusiasmada com estes resultados pelas possibilidades terapêuticas que oferecem: “o facto de termos descoberto que estão presentes células neurais estaminais e neurónios novos no hipocampo de idosos significa que poderemos conseguir desacelerar ou prevenir o declínio cognitivo nos idosos, especialmente quando este começa, que é quando as intervenções podem ser mais eficazes”, concluiu.

#Quais os perigos do slime caseiro para as crianças?

Quais os perigos do slime caseiro para as crianças?

 

Recentemente, o caso de uma menina de 12 anos internada em São Paulo por intoxicação exógena após brincadeira com slime repercutiu em diferentes noticiários e redes sociais1. A criança estava internada por mais de uma semana com um quadro de gastroenterite associada a um aumento de linfonodos. Os exames complementares não constatavam alterações e o médico, segundo a mãe da criança, desconfiou dos slimes que a menina produzia no quarto do hospital, concluindo que o quadro clínico da criança era atribuído a uma intoxicação por ácido bórico1. Contudo este não é um caso isolado

O que é slime?

Slime é uma palavra inglesa cujo significado mais formal é “lodo”, “lama viscosa” ou “substância gelatinosa”2. Em tradução livre quer dizer “gosma” ou “baba”1. O slime é um modismo atual que se tornou popular entre crianças e adolescentes em diversos países. O preparo do slime caseiro diverte tanto quanto brincar com ele e existem diversos tutoriais disponíveis online para cria-lo com diferentes texturas e aparências3,4. O slime caseiro é semelhante a produtos industrializados (Amoeba®, Geleka®) e é feito à mão por crianças. No entanto, sua preparação é baseada, muitas vezes, em uma mistura de itens, como cola de polivinil acetato (a cola branca de escola), água e ácido bórico (H3BO3), também conhecido como borato de sódio ou bórax.

O bórax age como um “ativador” que se combina com moléculas de cola na água para formar ligações fracas. As moléculas então se movem juntas, mas não endurecem, tornando-se um polímero elástico. A receita básica pode ser aprimorada pela adição de outros compostos para obter variadas densidades e efeitos de cores. Algumas adições comuns são espuma de barbear (que deixa o slime “fofo”), detergentes, soluções para lentes de contato, bem como corantes, esmaltes e glitter3,4,5,6,7. Infelizmente, acidentes durante o preparo caseiro dos slimes, principalmente com o bórax, envolvendo ingestão, inalação ou contato, foram relatados recentemente, e a gravidade varia de acordo com o conteúdo e/ou a quantidade do produto7.

Perigos do Bórax

O bórax é encontrado no ambiente e pode estar presente naturalmente em alimentos (como frutas e legumes) e água potável. No entanto, inúmeros produtos o apresentam em sua composição, não apenas os slimes, mas também pesticidas, produtos de limpeza, materiais de artesanato, cosméticos, produtos químicos para piscinas e medicamentos8.

Relatos de intoxicação infantil pelo bórax eram comuns na literatura médica antes de 1975. No entanto, um declínio no seu uso como agente bacteriostático, juntamente com um aumento no controle regulatório, quase eliminou as intoxicações por ingestão acidental. O Anexo I (Parte I, Item 8) da Hazardous Products Act of Canada (Lei de Produtos Perigosos do Canadá), proclamada no final dos anos 60, seguiu-se à preocupação com o envenenamento acidental e proibiu seu uso em brinquedos. Desde então, o conhecimento científico aumentou e levou a uma reavaliação do perigo associado ao bórax4.

Recente avaliação de risco do bórax pela agência nacional de saúde canadense Health Canada descobriu que a exposição excessiva ao bórax tem o potencial de causar efeitos no desenvolvimento e na saúde reprodutiva. Como os canadenses já estão expostos ao bórax naturalmente por meio de suas dietas e água, a Health Canada recomenda que a exposição por meio de outras fontes seja reduzida o máximo possível, especialmente para crianças e gestantes. A preocupação não é com qualquer produto, mas com múltiplas exposições de uma variedade de fontes. Atualmente, a Health Canada está aconselhando os canadenses a evitar o uso do bórax em projetos de artes e brinquedos, como slimes ou modelagem de argila, e desaconselha a fabricação de pesticidas caseiros com bórax8.

No Brasil, a Agência Nacional de Vigilância Sanitária (Anvisa) divulgou recente comunicado alertando que o bórax vem sendo usado e vendido inadequadamente como ativador do slime. O uso do bórax com esta finalidade não é regulamentado pela Anvisa, inclusive a agência proibiu, em 2002, a comercialização de um brinquedo conhecido como “Meleca Louca” exatamente devido à presença do bórax.

Portanto, seu uso deve ser restrito aos fins autorizados (como na composição de fertilizantes, produtos de limpeza e determinados medicamentos) e nas doses recomendadas pelas autoridades competentes. Trata-se de um produto químico, não devendo ser manipulado por crianças. Se inalado ou ingerido, pode causar intoxicação e levar às seguintes manifestações clínicas: náuseas, vômitos, cólicas abdominais, diarreia com coloração esverdeada/azulada, cianose de extremidades ou central, hipotensão, perda de consciência e choque cardiovascular9.

Além disso, o contato manual com esses ingredientes utilizados para o preparo do slime caseiro e/ou produto final pode causar reações adversas na pele, como dermatite de contato. A gravidade pode variar de acordo com o produto manipulado e a duração da exposição7. Alergênicos e irritantes são mais propensos a causar dermatite em concentrações mais altas, com uso prolongado ou quando a barreira cutânea está comprometida. As manifestações clínicas incluem eritema, descamação, vesículas e, em casos mais crônicos, distrofia ungueal, incluindo onicomadese4.

Com o contato repetido, pode haver sintomas persistentes de edema, sensação de formigamento e vermelhidão. O bórax tem um pH de 9,0, portanto, pode causar uma queimadura alcalina5. Além disso, a cola contém acetato de polivinila, um plástico incompleto, e pode conter metilcloroisotiazolinona e metilisotiazolinona, dois alérgenos de contato bastante conhecidos3. Outros alérgenos de contato conhecidos também são encontrados na espuma de barbear, nas soluções para lentes de contato e em detergentes líquidos usados no preparo dos slimes, como o lauril sulfato de sódio, miristamidopropil dimetilamina e propilenoglicol3.

Precauções

Algumas precauções devem ser tomadas pelos pais no intuito de evitar complicações relacionadas ao bórax em crianças8:

  • Usar receitas caseiras para slime que não contenham o bórax;
  • Verificar o rótulo de produtos para termos como “bórax” e “ácido bórico”. Você também pode entrar em contato com o fabricante para saber se seus produtos contêm ácido bórico;
  • Seguir todas as instruções sobre produtos de limpeza. Armazenar os produtos de limpeza fora da visão e do alcance das crianças;
  • Descarte os produtos químicos corretamente com base nas instruções do fabricante8.

A Anvisa recomenda as seguintes medidas em caso de suspeita de intoxicação pelo bórax9:

  • Não provocar vômitos;
  • Não ingerir água, leite ou qualquer outro líquido.
  • Contactar o Centro de Informações Toxicológicas (CIT) local. Se recomendado pelo atendente do centro, procurar atendimento médico com urgência9.
