Transposition of the great arteries is a serious but rare heart defect present at birth (congenital), in which the two main arteries leaving the heart are reversed (transposed). Transposition of the great arteries changes the way blood circulates through the body, leaving a shortage of oxygen in blood flowing from the heart to the rest of the body. Without an adequate supply of oxygen-rich blood, the body can't function properly and your child faces serious complications or death without treatment.

Pregnancy is one of the beautiful phases of a woman’s life after their marriage. The feeling of the baby growing inside the womb is exceptional and very special.

If you have placenta previa, it means that your placenta is lying unusually low in your uterus, next to or covering your cervix. The placenta is the pancake-shaped organ – normally located near the top of the uterus – that supplies your baby with nutrients through the umbilical cord.

What does the placenta do? The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it. In most pregnancies, the placenta attaches at the top or side of the uterus.

Sepsis is a potentially life-threatening complication of an infection. Sepsis occurs when chemicals released into the bloodstream to fight the infection trigger inflammatory responses throughout the body. This inflammation can trigger a cascade of changes that can damage multiple organ systems, causing them to fail. If sepsis progresses to septic shock, blood pressure drops dramatically, which may lead to death. Anyone can develop sepsis, but it's most common and most dangerous in older adults or those with weakened immune systems. Early treatment of sepsis, usually with antibiotics and large amounts of intravenous fluids, improves chances for survival. Symptoms & causes Symptoms Many doctors view sepsis as a three-stage syndrome, starting with sepsis and progressing through severe sepsis to septic shock. The goal is to treat sepsis during its early stage, before it becomes more dangerous. Sepsis To be diagnosed with sepsis, you must exhibit at least two of the following symptoms, plus a probable or confirmed infection: Body temperature above 101 F (38.3 C) or below 96.8 F (36 C) Heart rate higher than 90 beats a minute Respiratory rate higher than 20 breaths a minute Severe sepsis Your diagnosis will be upgraded to severe sepsis if you also exhibit at least one of the following signs and symptoms, which indicate an organ may be failing: Significantly decreased urine output Abrupt change in mental status Decrease in platelet count Difficulty breathing Abnormal heart pumping function Abdominal pain Septic shock To be diagnosed with septic shock, you must have the signs and symptoms of severe sepsis — plus extremely low blood pressure that doesn't adequately respond to simple fluid replacement. When to see a doctor Most often sepsis occurs in people who are hospitalized. People in the intensive care unit are especially vulnerable to developing infections, which can then lead to sepsis. If you get an infection or if you develop signs and symptoms of sepsis after surgery, hospitalization or an infection, seek medical care immediately. Causes While any type of infection — bacterial, viral or fungal — can lead to sepsis, the most likely varieties include: Pneumonia Abdominal infection Kidney infection Bloodstream infection (bacteremia) The incidence of sepsis appears to be increasing in the United States. The causes of this increase may include: Aging population. Americans are living longer, which is swelling the ranks of the highest risk age group — people older than 65. Drug-resistant bacteria. Many types of bacteria can resist the effects of antibiotics that once killed them. These antibiotic-resistant bacteria are often the root cause of the infections that trigger sepsis. Weakened immune systems. More Americans are living with weakened immune systems, caused by HIV, cancer treatments or transplant drugs. Risk factors Sepsis is more common and more dangerous if you: Are very young or very old Have a compromised immune system Are already very sick, often in a hospital's intensive care unit Have wounds or injuries, such as burns Have invasive devices, such as intravenous catheters or breathing tubes Complications Sepsis ranges from less to more severe. As sepsis worsens, blood flow to vital organs, such as your brain, heart and kidneys, becomes impaired. Sepsis can also cause blood clots to form in your organs and in your arms, legs, fingers and toes — leading to varying degrees of organ failure and tissue death (gangrene). Most people recover from mild sepsis, but the mortality rate for septic shock is nearly 50 percent. Also, an episode of severe sepsis may place you at higher risk of future infections.

Virtual Ports, Ltd. (http://www.virtual-ports.com) is a medical device company developing and marketing instruments to improve minimally invasive laparoscopic procedures.
The EndoGrab retraction system reduces the number of ports needed for surgery by eliminating the need for traditional hand held retraction. For the surgeon, this simple solution results in the need for less auxiliary personnel, a decreased overall surgery cost, and more control over the surgery. The EndoGrab also offers added benefit to the patient who will experience less post-operative discomfort and scarring.

The EndoGrab is an internally anchored, hands-free retracting device that is introduced at the start of surgery through a 5mm trocar by means of a proprietary Applier tool. The Surgeon uses the Applier to attach the EndoGrab to both the organ requiring retraction and to the internal abdominal wall, thereby removing the organ from the operative field. The Applier is then removed and the port is free for use by other instruments.

Tobacco use is the most common preventable cause of death. About half of the people who don't quit smoking will die of smoking-related problems. Quitting smoking is important for your health. Soon after you quit, your circulation begins to improve, and your blood pressure starts to return to normal. Your sense of smell and taste return, and it's easier for you to breathe. In the long term, giving up tobacco can help you live longer. Your risk of getting cancer decreases with each year you stay smoke-free. Quitting is not easy. You may have short-term affects such as weight gain, irritability, and anxiety. Some people try several times before they succeed. There are many ways to quit smoking. Some people stop "cold turkey." Others benefit from step-by-step manuals, counseling, or medicines or products that help reduce nicotine addiction. Some people think that switching to e-cigarettes can help you quit smoking, but that has not been proven. Your health care provider can help you find the best way for you to quit.

Osteoporosis is a disease in which bones become brittle and fragile due to low bone mass and bone tissue loss. It's the most common type of bone disease, according to the National Institutes of Health (NIH), and increases your risk of fractures, particularly of the hips, spine, and wrists. Prevalence In the United States, nearly 54 million people ages 50 and older were living with osteoporosis or osteopenia (low bone mass ) in 2010, according to a 2014 article in the Journal of Bone and Mineral Research. More specifically, 10.2 million adults had osteoporosis, and 43.4 million adults had osteopenia, which puts a person at high risk for osteoporosis.
