Transmission and Prevention of HIV and AIDS
Transmission and Prevention of HIV and AIDS Alicia Berger 30,391 Views • 2 years ago

HIV is spread only in certain body fluids from a person infected with HIV. These fluids are blood, semen, pre-seminal fluids, rectal fluids, vaginal fluids, and breast milk. In the United States, HIV is spread mainly by having sex or sharing injection drug equipment, such as needles, with someone who has HIV. To reduce your risk of HIV infection, use condoms correctly every time you have vaginal, oral, or anal sex. Don’t inject drugs. If you do, use only sterile injection equipment and water and never share your equipment with others. Pre-exposure prophylaxis (PrEP) is an HIV prevention option for people who don’t have HIV but who are at high risk of becoming infected with HIV. PrEP involves taking a specific HIV medicine every day. PrEP should always be combined with other prevention options, such as condoms.

Como Engravidar De Menino, Engravidar De Uma Menina, Como Faço Para Engravidar De Menina. Revelado: Maneira Incomum para Engravidar de uma MENINA! Fiquei impressionada pela grande quantidade de mulheres que possuem uma preferência para o sexo do seu bebê, e portanto vou falar hoje de como aumentar as suas chances de conceber uma menininha! Para aumentar as chances de engravidar de uma menina, devem-se considerar as características dos espermatozoides que carregam o gene X (que irá gerar uma menina) e dos que carregam o gene Y (que gerará um menino). Os espermatozoides femininos são mais lentos, porém mais resistentes que os espermatozoides masculinos. E como mencionei lá em cima a duração é diferente: os espermatozoides que carregam o gene X duram, em média, 72 horas, já os que carregam o gene Y duram menos, cerca de 24 horas. Com essas informações, a dica é ter relações sexuais dois ou três dias antes do período fértil, visto que os espermatozoides femininos são mais resistentes e conseguem “sobreviver” no corpo da mulher até que ela esteja ovulando. Para calcular o período fértil, deve-se considerar o dia da ovulação (em média, 14 dias após o primeiro dia da menstruação) e deixar uma margem de três dias antes e três dias depois da ovulação. Para saber o dia da ovulação, existem testes vendidos em farmácias, que funcionam como os testes de gravidez. Outra dica é observar o muco cervical, que fica com aspecto de clara de ovo no período fértil. Outra recomendação é adotar posições em que a penetração não seja tão profunda. É importante ainda que a mulher tenha orgasmo depois do homem, porque a secreção que ela libera quando atinge o clímax deixa a vagina menos ácida, facilitando a movimentação dos espermatozoides que carregam o gene Y (que irá gerar um menino). No caso da alimentação deve alterar o cardápio algumas semanas antes da ovulação, dando preferência para alimentos com muito cálcio e em magnésio como leite e derivados, frutas, verduras verde-escuras, como espinafre, couve e rúcula. Além disso, é necessário evitar comidas com muito sódio e potássio e reduzir o consumo de carne.

Living with Lewy Body Dementia - Mayo Clinic
Living with Lewy Body Dementia - Mayo Clinic samer kareem 1,809 Views • 2 years ago

LBD is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known diseases like Alzheimer’s and Parkinson’s, it is currently widely underdiagnosed. Many doctors or other medical professionals still are not familiar with LBD. LBD is an umbrella term for two related diagnoses. LBD refers to both Parkinson’s disease dementia and dementia with Lewy bodies. The earliest symptoms of these two diseases differ, but reflect the same underlying biological changes in the brain. Over time, people with both diagnoses will develop very similar cognitive, physical, sleep, and behavioral symptoms. While it may take more than a year or two for enough symptoms to develop for a doctor to diagnose LBD, it is critical to pursue a formal diagnosis. Early diagnosis allows for important early treatment that may extend quality of life and independence. LBD is a multisystem disease and typically requires a comprehensive treatment approach. This approach involves a team of physicians from different specialties who collaborate to provide optimum treatment of each symptom without worsening other LBD symptoms. Many people with LBD enjoy significant improvement of their symptoms with a comprehensive approach to treatment, and some can have remarkably little change from year to year. Some people with LBD are extremely sensitive or may react negatively to certain medications used to treat Alzheimer’s or Parkinson’s in addition to certain over-the-counter medications.

Cystic Fibrosis Pulmonary Disease
Cystic Fibrosis Pulmonary Disease samer kareem 1,770 Views • 2 years ago

Cystic fibrosis (CF) is a multisystem disease affecting the digestive system, sweat glands, upper and lower respiratory tracts, and the reproductive tract, but progressive lung disease continues to be the major cause of morbidity and mortality [1]. CF is characterized by abnormal transport of chloride and sodium across the respiratory epithelium, resulting in thickened, viscous airway secretions [2]. Over a highly variable time course ranging from months to decades after birth, individuals eventually develop chronic infection of the respiratory tract with a characteristic array of bacterial flora [3], leading to progressive respiratory insufficiency and eventual respiratory failure. The rate of progression varies widely, depending in part on genotype (including gene modifiers) as well as environmental factors. Registry data from CF Centers in the United States, Canada, and Europe indicate a median survival of about 41 years [4]. Females with CF appear to have higher morbidity and mortality than males [5]. This "gender gap" is modest but consistent across many populations and is hypothesized to be due to the pro-inflammatory effects of estrogens.

Osteoporosis and How to prevent it
Osteoporosis and How to prevent it samer kareem 2,864 Views • 2 years ago

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced. Osteoporosis occurs when the creation of new bone doesn't keep up with the removal of old bone. Osteoporosis affects men and women of all races. But white and Asian women — especially older women who are past menopause — are at highest risk. Medications, healthy diet and weight-bearing exercise can help prevent bone loss or strengthen already weak bones.

Vitamin D Deficiency
Vitamin D Deficiency samer kareem 2,626 Views • 2 years ago

The "sunshine" vitamin is a hot topic. You may have recently found out that you are deficient or know someone who is. It's shocking for most people when they have never had a problem before and believe nothing has changed to make it a problem now. The truth is that a lot has changed, and vitamin D deficiency and insufficiency is now a global public-health problem affecting an estimated 1 billion people worldwide. The most well-known consequences to not having enough vitamin D are rickets in children and osteomalacia in adults. These are far from the only problems associated with a vitamin D deficiency.

GERD  & IBS
GERD & IBS samer kareem 2,506 Views • 2 years ago

Gastroesophageal reflux disease (GERD) is a chronic digestive disease. GERD occurs when stomach acid or, occasionally, stomach content, flows back into your food pipe (esophagus). The backwash (reflux) irritates the lining of your esophagus and causes GERD. Both acid reflux and heartburn are common digestive conditions that many people experience from time to time. When these signs and symptoms occur at least twice each week or interfere with your daily life, or when your doctor can see damage to your esophagus, you may be diagnosed with GERD. Most people can manage the discomfort of GERD with lifestyle changes and over-the-counter medications. But some people with GERD may need stronger medications, or even surgery, to reduce symptoms.

Missing your Period!?
Missing your Period!? samer kareem 2,119 Views • 2 years ago

Most women have between 11 and 13 menstrual periods each year. You may be different: You may have more or fewer. Missed or irregular periods must be looked at in terms of what is normal for you. Menstrual periods are often irregular during the first few years after menstruation starts. It may take several years for the hormones that control menstruation to reach a balance. Menstrual periods also may be very irregular at the other end of the menstrual years. Many women realize that they are approaching perimenopause and menopause when their otherwise regular periods become irregular. Menopause occurs when it has been 12 months since you had a menstrual period. Pregnancy is the most common cause of a missed period. If you might be pregnant, treat yourself as if you are pregnant until you know for sure. Use a home pregnancy test as the first step to finding out whether you are pregnant.

Cushing's Syndrome
Cushing's Syndrome samer kareem 2,135 Views • 2 years ago

Cushing syndrome occurs when your body is exposed to high levels of the hormone cortisol for a long time. Cushing syndrome, sometimes called hypercortisolism, may be caused by the use of oral corticosteroid medication. The condition can also occur when your body makes too much cortisol on its own. Too much cortisol can produce some of the hallmark signs of Cushing syndrome — a fatty hump between your shoulders, a rounded face, and pink or purple stretch marks on your skin. Cushing syndrome can also result in high blood pressure, bone loss and, on occasion, type 2 diabetes. Treatments for Cushing syndrome can return your body's cortisol production to normal and noticeably improve your symptoms. The earlier treatment begins, the better your chances for recovery.

Ventricular Rupture - Cardiac Injury
Ventricular Rupture - Cardiac Injury samer kareem 1,560 Views • 2 years ago

Myocardial rupture occurs in the setting of acute myocardial infarction (AMI), blunt and penetrating cardiac trauma, primary cardiac infection, primary and secondary cardiac tumors, infiltrative diseases of the heart, and aortic dissection. Myocardial rupture (or perforation) may also occur iatrogenically during percutaneous cardiac procedures (including device implantation) or open heart surgery (particularly valve replacement). Recently, myocardial rupture has been reported in the setting of stress cardiomyopathy (Takotsubo or regional ventricular ballooning syndrome). The clinical presentation of myocardial rupture depends on the mechanism and site of injury and the hemodynamic effects of the rupture. Mortality is extremely high unless early diagnosis is made and urgent surgical intervention is provided.

Children Born Addicted To Drugs
Children Born Addicted To Drugs samer kareem 2,345 Views • 2 years ago

Shaking violently in a hospital crib, two tiny legs twitch and shudder uncontrollably. Wailing, muscle clenching and gasping for breath accompany the disturbing fit-like seizure. But, what makes the image all the more heartbreaking, is the newborn baby's diagnosis. Despite being just weeks old, the tiny baby is suffering the effects of drug withdrawal, having been born addicted to opioids. Every 19 minutes a child in the US is born with an opioid addiction - a devastating affliction inherited from their drug-addict mothers. While for most newborns the first precious weeks of life are full of love, care and adoration, for babies born addicted to drugs their first weeks are long, agonizing and distressing as they battle neonatal abstinence syndrome.

Cardiac Cycle - Systole & Diastole
Cardiac Cycle - Systole & Diastole samer kareem 2,889 Views • 2 years ago

Near the end of diastole, the ventricles nearly fill with blood, and then the atria contract, adding even more volume to the ventricles. The volume of blood in the ventricles at the end of diastole is referred to as the end-diastolic volume. The other phase of the cardiac cycle is called systole.

Obstructive Sleep Apnea Syndrome
Obstructive Sleep Apnea Syndrome samer kareem 2,001 Views • 2 years ago

What Is Sleep Apnea? When you have this condition, your breath can become very shallow or you may even stop breathing -- briefly -- while you sleep. It can happen many times a night in some people. Obstructive sleep apnea happens when something partly or completely blocks your upper airway during shut-eye. That makes your diaphragm and chest muscles work harder to open the obstructed airway and pull air into the lungs. Breathing usually resumes with a loud gasp, snort, or body jerk. You may not sleep well, but you probably won't be aware that this is happening.

How to Perform CPR - Emergency
How to Perform CPR - Emergency samer kareem 11,134 Views • 2 years ago

Anybody can and anybody should learn how to perform CPR (Cardiopulmonary resuscitation): According to the American Heart Association, a stunning 70% of Americans don’t know how what to do if somebody is experiencing a cardiac emergency because they don’t know how to administer CPR or they forgot the exact technique. This is especially alarming since almost 90% of cardiac arrests occur at home — where patients depend on the immediate respiratory care response of their family members. In brief, knowing how to perform CPR can save the life of a loved one someday.

Cluster Headaches
Cluster Headaches samer kareem 6,671 Views • 2 years ago

Cluster headaches, occur in cyclical patterns or clusters, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop. During remission, no headaches occur for months and sometimes even years. Fortunately, cluster headache is rare and not life-threatening. Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.

Pheochromocytoma
Pheochromocytoma samer kareem 3,085 Views • 2 years ago

A pheochromocytoma (fee-o-kroe-moe-sy-TOE-muh) is a rare, usually noncancerous (benign) tumor that develops in cells in the center of an adrenal gland. You have two adrenal glands, one above each kidney. Your adrenal glands produce hormones that give instructions to virtually every organ and tissue in your body. If you have a pheochromocytoma, an adrenal gland releases hormones that cause persistent or episodic high blood pressure. If left untreated, a pheochromocytoma can result in severe or life-threatening damage to other body systems, especially the cardiovascular system. Most people with a pheochromocytoma are between the ages of 20 and 50, but the tumor can develop at any age. Surgical treatment to remove a pheochromocytoma usually returns blood pressure to normal.

Thyroiditis
Thyroiditis samer kareem 1,816 Views • 2 years ago

Thyroiditis is a general term that refers to “inflammation of the thyroid gland”. Thyroiditis includes a group of individual disorders causing thyroidal inflammation but presenting in different ways. For example, Hashimoto’s thyroiditis is the most common cause of hypothyroidism in the United States. Postpartum thyroiditis, which causes temporary thyrotoxicosis (high thyroid hormone levels in the blood) followed by temporary hypothyroidism, is a common cause of thyroid problems after the delivery of a baby. Subacute thyroiditis is the major cause of pain in the thyroid. Thyroiditis can also be seen in patients taking the drugs interferon and amiodarone.

What Causes Strokes
What Causes Strokes samer kareem 6,093 Views • 2 years ago

A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die. A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke)
