National Blood Donor Month

Posted on January 9, 2023 by Jacob Lobosco

Approximately every two seconds, someone in the United States needs a transfusion of blood, platelets, or plasma. However, this critically-needed blood is often in short supply, as only about 3% of eligible people donate blood each year.

A steady supply of donated blood is necessary for transfusions during a wide range of surgical procedures to counteract any blood loss that may occur. Approximately 21 million blood components are transfused throughout the U.S. each year.

Blood donations are also crucial for treating severe injuries. Victims of car accidents who have incurred severe injuries and blood loss can sometimes require as many as 100 units of blood; a healthy human body, in comparison, typically only holds about 10 units of blood at any given time. Additionally, transfusions are an essential part of treatment for chronic conditions that cause anemia, such as cancer or kidney disease.

There are four common types of donations: whole blood donations, red blood cell donations, plasma donations, and platelet donations.

Whole blood donations: This type of donation contributes approximately one pint of blood and includes all contents of the blood, including red blood cells, platelets, and plasma.

Red blood cell donations: People who meet certain height and weight requirements may be able to donate only their red blood cells; your platelets and plasma are returned to your bloodstream.

Plasma donations: A plasma donation only contributes your plasma, which is most often needed to treat accident and burn victims. Plasma transports protein and nutrients throughout the body.

Platelet donations: Platelets enable blood clotting, which prevents blood loss after sustaining an injury. This type of donation is needed for various types of patients, including accident victims, cancer patients, and people with blood clotting problems.

To make a donation, you can schedule an appointment at a blood drive or donor center near your area through the New York Blood Center.

What Is Anemia?

Posted on September 14, 2022 by Jacob Lobosco

Anemia is the most common blood condition in the United States and affects over two billion people globally. More women suffer from iron deficiency anemia than men. Anemia reduces the number of healthy red blood cells available to carry oxygen throughout your body, leaving you feeling tired and weak.

The symptoms of anemia can range from mild and temporary to chronic and severe, potentially causing life-threatening complications such as heart failure. Severe symptoms may be more likely for people over the age of 65.

The severity of anemia mainly depends on its cause, which can include factors such as:

Deficiency of iron, folate, or vitamin B-12
Acute or chronic inflammatory diseases
Radiation and chemotherapy
Infections and autoimmune diseases
Exposure to toxic chemicals
Bone marrow disease
Blood disease
Genetics

Not all forms of anemia are preventable, particularly if it’s inherited genetically or the result of a condition with unclear causes. Increasing your intake of foods rich in iron, folate, and vitamins B-12 and C can help prevent certain forms of anemia or manage anemic symptoms.

Additionally, you may be able to prevent anemia associated with other conditions by managing the risk factors of those conditions. This may include reducing your intake of alcohol or avoiding exposure to toxic substances as much as possible.

A hematologist can provide treatment to help relieve anemia symptoms through intravenous infusions, red blood cell transfusions, bone marrow transplants, erythropoietin injections, or surgery to stop internal bleeding that may cause the condition.

If you’re looking for a diagnosis or anemia treatment, you can schedule an appointment with a hematologist at Jamaica Hospital Medical Center by calling (718) 206-7001.

Sickle Cell Awareness Month

Posted on September 7, 2022 by Jacob Lobosco

Over 100,000 Americans suffer from sickle cell disease. According to the National Heart, Lung, and Blood Institute, Black and Hispanic-American babies are most often born with the disease. Additionally, one in every 13 Black babies is born with sickle cell trait (HbAS), which generally doesn’t cause symptoms of sickle cell disease, but may lead to health issues in response to physical stresses such as dehydration or strenuous physical exercise.

A person with sickle cell disease has abnormal hemoglobin, causing their red blood cells to become hard and sticky. These cells form into a shape resembling a sickle and have a short life cycle, leading to a constant shortage of red blood cells and symptoms that include pain, infections, strokes, and acute chest syndrome.

There are also several different forms of sickle cell disease. Common types include:

Sickle cell anemia (HbSS), which causes standard sickle cell disease symptoms as well as potential issues such as delayed puberty and vision problems
HbSC, a typically mild form of sickle cell disease
HbS beta thalassemia, in which a child inherits the genes for both sickle cell disease and beta thalassemia, another cause of abnormal hemoglobin

Rare forms of sickle cell disease include:

HbSD, in which a child inherits the sickle cell “S” gene and a “D” gene
HbSE, in which a child inherits the “S” and “E” genes
HbSO, in which a child inherits the “S” and “O” genes

Sickle cell disease can be diagnosed through a blood test shortly after a baby’s birth or through a sample of the amniotic fluid surrounding a baby in the womb. A blood test can also be used to diagnose an adult with sickle cell disease.

People with sickle cell disease can manage their symptoms by staying hydrated, regulating their body temperature, and avoiding spaces with low oxygen levels. Practicing good hand hygiene can also help.

If you need help managing symptoms of sickle cell disease or sickle cell trait, schedule an appointment with a hematologist at Jamaica Hospital Medical Center’s Department of Internal Medicine at (718) 206-7001.

September is Sickle Cell Awareness Month

Posted on September 18, 2015 by Michael Hinck

September has been designated National Sickle Cell Awareness Month to bring attention to this genetic disease that affects an estimated 100,000 Americans.

Sickle cell disease is an inherited form of anemia – a condition in which red blood cells are unable to carry oxygen throughout the body. For most, red blood cells are round and can move easily through blood vessels, but the red blood cells in people with sickle cell disease are crescent, or half-moon shaped. These irregular shaped cells can get stuck in blood vessels, which can slow or block the flow of oxygen to certain parts of the body.

In addition to being irregular in shape, sickle cells are fragile and break apart easily. Normal red blood cells live an average of four months before they die and need to be replaced. Sickle-shaped cells however only live an average of 20 days. The result of this shortage of blood cells is a loss of energy and general sense of fatigue.
Other symptoms of sickle cell disease include:

• Hand-Foot Syndrome – Often the first sign of sickle cell disease. It is caused by a lack of blood flow to the hands and feet

• Episodes of Pain – Referred to as a “crisis”, these episodes of pain occur when blood flow is blocked to the chest, abdomen, and joints. The frequency and duration of the episodes vary from person to person, but in severe cases, they can result in hospitalization.

• Frequent Infections and Fever– Sickle Cell can cause damage to the spleen, an organ that fights infection, making those with sickle cell at greater risk of developing an infection and an accompanying fever.

• Changes in Skin – People with sickle cell disease can develop a yellow tint to their skin or the whites of their eyes. Skin and nail beds can often become pale.

• Delayed growth – By not receiving enough oxygen rich red blood cells, those with sickle cell disease may also not get the necessary nutrients essential for growth.

The risk of inheriting sickle cell disease is a genetic one. For a baby to be born with it, both parents must carry the sickle cell gene. Doctors can diagnose sickle cell disease before a child is born. Couples who are at risk for passing on this disease to their children may want to talk with a genetic counselor about prenatal testing. The sickle cell gene is more common in families that come from Africa, India, Carribbean islands, and Central and South America.

To determine if you have sickle cell disease, your doctor can order a test to check for hemoglobin S, the defective form of hemoglobin that underlies sickle cell anemia. Further tests can confirm the existence of one gene (carrying the sickle cell trait) or two genes (sickle cell anemia). For those who have sickle cell anemia, treatment is aimed at treating the symptoms and avoiding crisis. Regular check-ups to monitor your red blood cell count are important. Medications are available to reduce pain and prevent complications can be prescribed, and blood transfusions, supplemental oxygen and even bone marrow transplants may also be necessary.

Jamaica Hospital serves a culturally rich and diverse population. Many members of our community are from the parts of the world most often affected by sickle cell disease. In recognition of National Sickle Cell Awareness Month, Jamaica Hospital’s encourages anyone living with sickle cell disease to carefully manage their condition. The hospital also recommends all potential parents to be tested for the sickle cell trait.
