What Is Multiple Myeloma? 

Cancer starts when cells begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas.

Multiple myeloma is a cancer of plasma cells. Normal plasma cells are found in the bone marrow and are an important part of the immune system. The immune system is made up of several types of cells that work together to fight infections and other diseases. Lymphocytes (lymph cells) are one of the main types of white blood cells in the immune system and include T cells and B cells. Lymphocytes are in many areas of the body, such as lymph nodes, the bone marrow, the intestines, and the bloodstream.

When B cells respond to an infection, they mature and change into plasma cells. Plasma cells make the antibodies (also called immunoglobulins) that help the body attack and kill germs. Plasma cells, are found mainly in the bone marrow. Bone marrow is the soft tissue inside bones. In addition to plasma cells, normal bone marrow is also the home for other blood cells such as red cells, white cells, and platelets.

In general, when plasma cells become cancerous and grow out of control, this is called multiple myeloma. The plasma cells make an abnormal protein (antibody) known by several different names, including monoclonal immunoglobulin, monoclonal protein (M-protein), M-spike, or paraprotein.

Zinc supplementation may exacerbate rheumatoid arthritis (RA), new laboratory data suggest.

In monocytes from rheumatoid arthritis patients, plasma zinc concentrations and Zip8 expression were increased, and Zip8 expression correlated with more severe disease. Thus, inhibiting zinc influx into monocytes and macrophages could prevent excessive inflammatory responses that occur in diseases such as rheumatoid arthritis – the researchers concluded.

Bacteria may Demonstrate any of Five General Mechanisms of Antibiotic Resistance: 
1. Lack of entry; Decreased cell permeability. 
2. Greater exit; Active efflux. 
3. Enzymatic inactivation of the antibiotic. 
4. Altered target; Modification of drug receptor site. 
5. Synthesis of resistant metabolic pathway. 

More than HIV, more than malaria. The death toll worldwide from bacterial antimicrobial resistance (AMR) in 2019 exceeded 1.2 million people, according to a new study. 

In terms of preventable deaths, 1.27 million people could have been saved if drug-resistant infections were replaced with infections susceptible to current antibiotics. Furthermore, 4.95 million fewer people would have died if drug-resistant infections were replaced by no infections, researchers estimated.
