Talk:Hemostasis

message: Two of the paragraphs of the current edition of the article read as follows:
"Platelet plug formation - Platelets adhere to damaged endothelium to form platelet plug (primary hemostasis) and then degranulate. Platelet Plug Formation: Platelets play one of the biggest factors in the hemostatic process. Being the second step in the sequence they stick together (aggregation) to form a plug that temporarily seals the break in the vessel wall. As platelets adhere to the collagen fibers of a wound they become spiked and much stickier. They then release chemical messengers such as adenosine diphosphate (ADP), serotonin and thromboxane A2. These chemicals are released to cause more platelets to stick to the area and release their contents and enhance vascular spasms. As more chemicals are released more platelets stick and release their chemicals; creating a platelet plug and continuing the process in a positive feedback loop. Platelets alone are responsible for stopping the bleeding of unnoticed wear and tear of our skin on a daily basis.[3]
The second stage of Hemostasis involves platelets that move throughout the blood. When the platelets find an exposed area or an injury, they begin to form what is called a platelet plug. The platelet plug formation is activated by a glycoprotein called the Von Willebrand factor (VWF), which are found in the body’s blood plasma. When the platelets in the blood are activated, they then become very sticky so allowing them to stick to other platelets and adhere to the injured area."
Notice how the first paragraph already includes the "second step of the sequence" without making it explicit it is secondary hemostasis and explains the platelet plug formation. The following paragraph then describes the same thing, even saying that it begins to form what is called a platelet plug, when this term had already been introduced in the previous paragraph! It also mentions that platelets become more sticky, which was already covered previously as well. The only useful thing this paragraph introduces is the VWF. I suggest for the VWF part to be inserted in the first paragraph and the second paragraph to be erased entirely.

thread_title: Redudant paragraph

message: I particularly enjoyed how you chose to arrange the article. It has a very logical, clear flow to it. I wonder it you have too much detail in the introduction at the top of the page though? Perhaps that material should be included elsewhere. Just FYI as well, I'm not sure why, since I see your in text citations and end references, but wiki has this tagged as not having references.

replies: text: The mechanism and steps section areessentially duplitious. They should be merged. Don't have time to do the merger, but I'm going to make sure the steps are numbered sequentially. 129.180.166.53 (talk) 06:30, 10 June 2012 (UTC)
replies: text:   Done OK, I've done this myself. But we should look at why hemostasis and coag is different. Coag is a lot better quality of an article. 129.180.166.53 (talk) 06:51, 10 June 2012 (UTC)

message: I have no medical training, but I'm researching Hemostasis and Hemostatic Products as part of a larger project.
It seems like this article could be expanded, just based on the basic research I've done so far.  Again, I have no expertise to expand it myself...
Thanks!

thread_title: I

message: Note: This was initially posted on the article page by Dceferguson, so I moved it to the discussion page.
Currently, more and more in discussions relating to health status and fitness, particularly in relation to geriatric ftiness, health promotion, and in relation to exercise, hemostasis is increasingly used as a term to refer to health benefits of promoting hemostasis over and beyond assisting coagulation processes.  One is reminded of the use of the term homeostasis which extends beyond the simple concept of balancing sympathetic and parasympathetic nervous systems to broader notions of balancing bodily systems beyond them.  Given what is known about exercise and prevention of cognitive decline it seems likely that hemostatic processes go far beyond coagulation and such benefits are likely mediated by as yet not clearly defined changes in hemostatis.  Both muscles AND brain benefit by physical activity, both are mediated by improved blood supply and waste removal, and both are mediated by vascular patency and biochemically healthy changes within the blood itself beyond simple coagulation action. I would argue the concept of hemostasis needs broadening in the same way that homeostasis now covers a variety of component processes beyond the simple ones.  
Coagulation and related terms are quite adequate to describe what these activities do.  They are not in need of synonyms, however hemostasis as a concept which is increasingly being used to describe processes and functions which go beyond coagulatory housekeeping affords the opportunity to enlarge a term to a wider health related set of component functions.  Please note I intentionally have not specified specific particular additions, but hope to stimulate thought and debate as to what might be usefully added to the conceptual breadth of an increasingly utilized term.  
As a retired Professor of Preventive Medicine I recognize the need for additional ways to speak about and define health and wellness functions and processes. This concept presents a golden opportunity to enrich our technical conceptual language. We already have narrow operational definitions for most individual physiological functions, but have a limited repertoire of higher order concepts and terms that embrace multiple health related processes.  What does the Wikipedia community think, and what can be meaningfully and usefully subsumed under Hemostasis as a broader term so as to give it the more useful breadth it seems to cry out to embrace?  Necessity is said to be the mother of invention.  We know rather well what illness is, but simly try to define health as I have asked my physician MPH candidates to do as term papers and you will find yourself in deep conceptual water very quickly.

thread_title: Broad definition

message: I thought it was a very good start but I feel that in the overview it seems that what was already on the page was just reworded.  In the beginning of the page you talk about how when Greece took over Egypt they made medical advances, what were these advances?  The only other thing I saw was some of the wording could be redone.

thread_title:  Good article nomination 

message: I've removed all the uncited material from the article.  This is a major first step towards working towards WP:GAN.  The information should be replaced with new text and citations as it now leaves rather gaping holes in the article. :( When adding the information, please try to use prose instead of lists.  If you're inclined to use lists anyway, consider using tables instead as a better visualization tool.--LauraHale (talk) 03:00, 29 April 2012 (UTC)
