Why a different way to measure good cholesterol may be more useful

The Centers for Disease Control and Prevention (CDC) highlight that heart disease is the leading cause of death among almost all groups of people in the United States; 1 in 4 deaths in the country result from this type of illness. Although there are ongoing debates about the relationship between cholesterol and heart health, the CDC distinguish between good and bad cholesterol. Good cholesterol is better-known as high-density lipoprotein (HDL) cholesterol. Cholesterol travels through the body on lipoproteins, and this type brings cholesterol to the liver, which then removes it from the body. Traditionally, HDL levels are measured by determining the total amount of cholesterol being carried by HDL particles. However, recent research has suggested that measuring the number of particles of HDL (HDL-P), rather than the total amount of cholesterol that the particles carry (HDL-C) may be a better way of determining the association between HDL and cardiovascular diseases. The authors of the present study wanted to develop this research further to see the differences in the abilities of the two measures to predict cardiovascular disease. They also wanted to test whether being Black or white made any difference to the relationship between HDL and the risk of cardiovascular issues. According to Dr. Anand Rohatgi, an associate professor and preventive cardiologist at the University of Texas Southwestern Medical Center,Previous studies have looked at HDL levels in the population as a whole. But we know that sometimes biology differs by gender and race, so we thought it was important to separately tease apart what's happening in those populations, as well as how HDL is associated with stroke, which has been understudied,

Swollen knee

Swelling is a sign of inflammation. It is a buildup of fluid around a damaged area, and it usually causes the area to become larger and puffier. Inflammation, and therefore swelling, can be acute or chronic. Acute swelling may result from an injury and disappear within a day. Chronic swelling can last much longer and signal an underlying medical condition. Knee swelling may result from an underlying health issue, such as arthritis or an infection, or it may follow an injury. Several home care strategies can reduce the swelling, such as taking NSAIDs and using an ice pack. However, if a person suspects that the swelling results from an underlying condition, it is important to receive professional care. A doctor can assess the damage with imaging and provide treatments, such as antibiotics. Consult a doctor if knee pain does not improve with rest or occurs with other symptoms. Also, see a doctor after a sudden injury, such as from blunt force trauma. In addition, it is important to receive professional care if there are any indications of an infection, such as a fever or pus coming from a wound.
