Basic Projects of Diabetic


Diabetes Action Online
Recognising the increasing burden of diabetes on the health sector, Diabetes Action Online is dedicated to improving the quality of diabetes care. MV Diabetic Hospital in collaboration with the International Diabetes Federation (IDF), it speaks to decision makers at all levels of the health care system walking them through the improvement process with supporting documents, tools and expert guidance.


 Background
Diabetes Action Online is one of the five goals of the Diabetes Action Now programme, a joint programme of the MV Diabetic Hospital and the International Diabetes Federation (IDF). By stimulating and supporting the adoption of effective measures for the surveillance, prevention and control of diabetes, it aims to substantially increase the global awareness about diabetes and its complications.

Stem cells


Stem cells are biological cells found in all multicellular organisms, that can divide (through mitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells.

In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells (these are called pluripotent cells), but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.


There are three sources of autologous adult stem cells: 1) Bone marrow, which requires extraction by harvesting, that is, drilling into bone (typically the femur or iliac crest), 2) Adipose tissue (lipid cells), which requires extraction by liposuction, and 3) Blood, which requires extraction through pheresis, wherein blood is drawn from the donor (similar to a blood donation), passed through a machine that extracts the stem cells and returns other portions of the blood to the donor. Stem cells can also be taken from umbilical cord blood. Of all stem cell types, autologous harvesting involves the least risk. By definition, autologous cells are obtained from one's own body, just as one may bank his or her own blood for elective surgical procedures.


Highly plastic adult stem cells are routinely used in medical therapies, for example bone marrow transplantation. Stem cells can now be artificially grown and transformed (differentiated) into specialized cell types with characteristics consistent with cells of various tissues such as muscles or nerves through cell culture. Embryonic cell lines and autologous embryonic stem cells generated through therapeutic cloning have also been proposed as promising candidates for future therapies.Research into stem cells grew out of findings by Ernest A. McCulloch and James E. Till at the University of Toronto in the 1960s

Diabetic Kidney Disease


Diabetic Kidney Disease
  • High blood sugar can overwork the kidneys, causing them to stop working properly.
  • When diagnosed early, kidney disease can be slowed with treatment.
  • When diagnosed later, kidney failure usually results.
  • Once kidneys fail, replacement therapy via dialysis or transplant is necessary. 
Kidneys are remarkable organs. Inside them are millions of tiny blood vessels that act as filters. Their job is to remove waste products from the blood. 



Sometimes this filtering system breaks down. Diabetes can damage the kidneys and cause them to fail. Failing kidneys lose their ability to filter out waste products, resulting in kidney disease.

How does diabetes cause kidney disease?

When our bodies digest the protein we eat, the process creates waste products. In the kidneys, millions of tiny blood vessels (capillaries) with even tinier holes in them act as filters. As blood flows through the blood vessels, small molecules such as waste products squeeze through the holes. These waste products become part of the urine. Useful substances, such as protein and red blood cells, are too big to pass through the holes in the filter and stay in the blood.

Who gets kidney disease?

Not everyone with diabetes develops kidney disease. Factors that can influence kidney disease development include genetics, blood sugar control, and blood pressure.

What are the symptoms?

 

The kidneys work hard to make up for the failing capillaries so kidney disease produces no symptoms until almost all function is gone. Also, the symptoms of kidney disease are not specific. The first symptom of kidney disease is often fluid buildup. Other symptoms of kidney disease include loss of sleep, poor appetite, upset stomach, weakness, and difficulty concentrating.
