  5. immune system chapter – cell division as part of immune response in lymph nodes.

The news item:  Recently a recall of breast implants was in the news:

Breast implants tied to rare form of cancer recalled at FDA request

Allergan Inc. announces a worldwide recall of implants with a textured surface

The report described how one type of breast implant made by Allergan is associated with the development of a rare cancer, called anaplastic large cell lymphoma (ALCL).

So, Why Do I Care??  Altogether close to 600 anaplastic large cell lymphoma cases have been reported in women with breast implants. Even such a relatively slow number of cancers is a concern, because most of those cases occurred in women with one type of implant. Add to this that breast implants have been considered as a cosmetic alteration that presents little danger, but now a specific disorder is associated with them. That is a substantial change in how we view the risks of this procedure

Plain English, Please!!!

First, let’s talk about how a breast implant affects the body. This cosmetic implant is made of plastic, and it is surgically inserted under the skin. The normal wound

The news item:  Recently a Listeria outbreak was reported to have started from contaminated mushrooms:

Enoki mushrooms tied to listeria outbreak that killed four people and hospitalized 31, CDC says | CNN

Enoki mushrooms are linked to four deaths and 31 hospitalizations in what the US Centers for Disease Control and Prevention says was a multistate listeria outbreak that is now presumed to be over.

The article stated that Listeria outbreak is caused by a bacterium, and that the symptoms of infection are stiff neck, loss of balance, miscarriage, confusion and fever.

So, Why Do I Care??

Infection by Listeria bacterium is the third leading cause of food borne illness, and it is the most lethal food borne illness by killing about 15 – 20% of the infected individuals.  In the US each year about 1600 people get infected, and 260 die. The victims are the most vulnerable of society: elderly, pregnant women, and immunosuppressed people.

Plain English, Please!!!

First, let’s talk about what Listeria is. Listeria is a type of bacterium that infects human beings when they consume Listeria-contaminated food. The bacterium lives

  3. respiratory system chapter – alveoli location and function
  4. immune system chapter – events during inflammation
  5. microbiology – bacterial resistance against antibiotics

The news item:  Recently the news of a novel antibiotic was reported:

FDA approves new antibiotic for bacterial pneumonia

A new antibiotic has been approved by the Food and Drug Administration. It’s called Xenleta and the FDA says it’s another treatment option to fight a common type of pneumonia.

The article states that the new antibiotic, Xenleta, is a pleuromutilin, and it fights community acquired bacterial pneumonia.

So, Why Do I Care??

Pneumonia is the reason for 1 million hospitalizations and 50,000 deaths each year in the US. Most pneumonia cases are caused by bacterial infections. Because this disease can get worse quickly, efficient treatment must include the killing of the bacteria that cause the disease. Any new antibiotic that can treat people whose pneumonia resists the regular antibiotics likely to save thousands of lives each year.

Plain English, Please!!!

First, let’s talk about what bacterial pneumonia is. When the deepest portion of our respiratory system, the alveoli (air sacks), are attacked by bacteria, the result is local

  5. lymphatic and immune system chapter – antibody structure
  6. lymphatic and immune system chapter – antibodies are made for specific targets

The news item:  Recently reports appeared where blood plasma taken from recovered patients are given to seriously ill COVID-19 patients:

Blood plasma appears safe for COVID-19 patients in early trial results

Researchers report promising results in early safety trials of convalescent plasma therapy, in which the blood of COVID-19 survivors is used to treat patients.

The article mentions that antibodies in the plasma are the active ingredient, and that 5000 patients were evaluated in this trial to determine the safety of such treatment.

So, Why Do I Care??  Have you been living under a rock in the last few months??? The coronavirus, SARS-CoV-2, responsible for the COVID-19 disease has so far infected over 6 million people, and caused over 377,000 deaths worldwide (on the date of this article). The virus attacks the respiratory system, specifically the alveoli, and may cause pneumonia and death by respiratory failure.  The antibodies from the recovered patients hold promise as a possible treatment to lower the lethality of the virus.
