Unusual treatment shows promise for kids with brain tumors | Pennsylvania State News

For decades, a deadly type of childhood cancer has eluded science’s best tools. Now doctors have made progress with an unusual treatment: Dripping millions of copies of a virus directly into kids’ brains to infect their tumors and spur an immune system attack.

A dozen children treated this way lived more than twice as long as similar patients have in the past, doctors reported Saturday at an American Association for Cancer Research conference and in the New England Journal of Medicine.

Although most of them eventually died of their disease, a few are alive and well several years after treatment — something virtually unheard of in this situation.

“This is the first step, a critical step,” said the study’s leader, Dr. Gregory Friedman, a childhood cancer specialist at the University of Alabama at Birmingham.

“Our goal is to improve on this,” possibly by trying it when patients are first diagnosed

Bad Breath Causes, Treatments, and Prevention

Bad breath, medically called halitosis, can result from poor dental health habits and may be a sign of other health problems. Bad breath can also be made worse by the types of foods you eat and other unhealthy lifestyle habits.

How Does What You Eat Affect Breath?

Basically, all the food eaten begins to be broken down in your mouth.  If you eat foods with strong odors (such as garlic or onions), brushing and flossing — even mouthwash — merely covers up the odor temporarily. The odor will not go away completely until the foods have passed through your body.

Why Do Poor Habits Cause Bad Breath?

If you don’t brush and floss teeth daily, food particles can remain in your mouth, promoting bacterial growth between teeth, around the gums, and on the tongue. This causes bad breath. Antibacterial mouth rinses also can help reduce bacteria.

In addition, odor-causing bacteria

Confusion over ivermectin, but regulator maintains it’s not approved for Covid-19 treatment

  • Reports have emerged that SAHPRA had agreed to allow ivermectin for Covid-19 treatment.
  • But the regulator says this is not true, and its position remains unchanged.
  • A cream containing ivermectin was recently approved though – to treat a skin condition.

The South African Health Products Regulatory Authority (SAHPRA) on Monday said reports of ivermectin being approved for use in Covid-19 are, “… grossly untrue, and misleading”.

In a statement, SAHPRA CEO Dr Boitumelo Semete said an erroneous report was placed by the SABC, that the body had agreed to allow for the use of ivermectin in treating Covid-19.

“This is grossly untrue, misleading to the public, and irresponsible, and could have dire consequences.”

Semete said the regulator’s position remained unchanged.

“Ivermectin may be prescribed and dispensed to patients without awaiting section 21 authorisation, but is still subject to receiving section 21 authorisation, informed consent, and all reporting requirements normally required

Iron Deficiency Anemia (Low Iron): Symptoms, Causes, Treatment

What Is Iron Deficiency Anemia?

Iron deficiency anemia is when your body doesn’t have enough red blood cells. 

Red blood cells carry oxygen from your lungs to the rest of your body. Every organ and tissue in your body needs oxygen to work. Without enough oxygen in your blood, and you may feel tired, weak, and short of breath.

You get iron deficiency anemia when your body is low in iron. You need iron to make hemoglobin, a protein that helps your red blood cells carry oxygen. 

Your doctor will find out why your iron is low. Usually, you can treat iron deficiency anemia with supplements. Once your iron levels go up, you should start to feel better.

Symptoms of Iron Deficiency Anemia

Mild iron deficiency anemia often isn’t noticeable. When it gets more severe, you may have these symptoms:

Because these can also be symptoms of other conditions, see

Dental Crowns: Purpose, Procedure, Complications, Care

A dental crown is a tooth-shaped “cap” that is placed over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance.

The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.

Why Is a Dental Crown Needed?

A dental crown may be needed in the following situations:

  1. To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth
  2. To restore an already broken tooth or a tooth that has been severely worn down
  3. To cover and support a tooth with a large filling when there isn’t a lot of tooth left
  4. To hold a dental bridge in place
  5. To cover misshapened or severely discolored teeth
  6. To cover a dental implant
  7. To make a cosmetic modification

For children, a crown may

That said, in the context of Working Agreements you can run the following:

Describe what the purpose of the exercise is. I like to use the following introduction and description of what a working agreement is, and how it can benefit a team:

“Becoming a team involves commitment to working together and supporting each other in our common goals.

How Does Exercise Affect the Body?

Many people today are interested in exercise as a way of
improving their health and physical abilities. But there is also
concern that too much exercise, or exercise that is not
appropriate for certain individuals, may actually do more harm
than good. Exercise has many short-term (acute) and long-term
effects that the body must be capable of handling for the
exercise to be beneficial. Some of the major acute effects of
exercising are shown in Figure 1. When we exercise, our heart

Autism: Signs and Symptoms

Autism spectrum disorder (ASD) can look different in different people. It’s a developmental disability that affects the way people communicate, behave, or interact with others. There’s no single cause for it, and symptoms can be very mild or very severe. 

Some children who are on the spectrum start showing signs as young as a few months old. Others seem to have normal development for the first few months or years of their lives and then they start showing symptoms.

But up to half of parents of children with ASD noticed issues by the time their child reached 12 months, and between 80% and 90% noticed problems by 2 years. Children with ASD will have symptoms throughout their lives, but it’s possible for them to get better as they get older.

The autism spectrum is very wide. Some people might have very noticeable issues, others might not. The common thread is

Gastric Sleeve Surgery Weight Loss You Can Expect (In Pounds)

HOW MUCH WEIGHT CAN YOU LOSE with Gastric Sleeve Surgery - Los Angeles

Gastric sleeve surgery is a useful tool in the fight against obesity.

The bariatric (weight loss) procedure, otherwise known as the sleeve gastrectomy or laparoscopic sleeve gastrectomy (LSG), reduces the size of your stomach, forcing you to eat less.

Once the bariatric surgery is performed, gastric sleeve patients go on to lose between 65% and 75% of their excess weight in the first two years.

However, percentages only tell you part of the story. You may want to know how much weight YOU stand to lose by undergoing the gastric sleeve.

To calculate your expected weight loss in pounds, it helps to explain a few things first.

To be eligible for the gastric sleeve, you must have a Body Mass Index (BMI) of 40, which indicates morbid obesity. In some cases, you can be approved for surgery with a BMI of 35 if one or more associated conditions are present.
