Do you know who can donate blood to you or who can you donate blood to? Blood donation may not be complex, but it does need to be compatible with yours and vice-versa. The blood types are determined by the presence or absence of certain antigens - substance that can trigger immune response if they are foreign to the body.
There are four major blood groups which are determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. There is also a protein called the Rh factor, which can either be present (+) or absent (-), which creates A+, A-, B+, B-, O+. O-, AB+, AB- blood types.
Group A blood type has only A antigens on red blood cells and B antibody in the plasma. B has only B antigen on red cells and A antibody in the plasma. AB has both A and antigens on red cells, but neither A nor B antibody is present in the plasma. O has neither A nor B antigens on red cells, but both A and B antibody are present in the plasma.
Your blood type determines who can you donate to. This is because there are very specific ways in which blood types must be matched for safe transfusion. The right blood transfusion could actually save you, while the wrong one could be lethal. Also, Rh-negative blood is given to Rh-negative patients and Rh-positive or Rh-negative blood can only be given to Rh-positive patients.
If you are O blood type, you can donate to O, A, B, and AB, if you are A blood type, you can donate to A and AB, if you are B blood type, you can donate to B and AB, however if you are AB, you can only donate to AB.
If you are O blood type, you can only receive from O. If you are A, you can receive from type A and O. If you are blood type B, you can receive from type B and O. If you are AB, you are lucky, you can receive blood from O, A, B, and AB.
There are more than 600 other known antigens, the presence or absence of which creates "rare blood types". Certain types are unique to specific ethnic or racial groups, this is why an African-American blood donation can be the best hope for the needs of patients with sickle cell disease, as per the Red Cross Organization.
Type O is one in high demand, as it can donate blood to anyone. O negative blood type is the universal blood type, which can donate to everyone, especially during the emergency transfusions and for immune deficient infants.
In the US, 37% Caucasian, 47% African-American, 39% Asians, and 53% Latino-American are O-positive. However, only 8% of Caucasian, 4% of African-American, 1% Asian, and 4% Latino=Americans are O-negative.
A+: 33% Caucasian, 34% African-American, 27% Asian, 29% Latino-American
A-: 7% Caucasian, 2% African-American, .5% Asian, 2% Latino-American
B+: 9% Caucasian, 18% African-American, 25% Asian, 9% Latino-American
B-: 2% Caucasian, 2% African-American, .4% Asian, 1% Latino-American
AB+:3% Caucasian, 4% African-American, 7% Asian, 2% Latino-American
AB-: 1% Caucasian, .3% African-American, .1% Asian, .2% Latino-American

During the COVID-19 pandemic, the SARS-CoV-2 virus had a significant impact on the eyes, causing conjunctivitis (pink eye), with red, itchy, watery, or painful eyes.
A new study now shows that eye symptoms may also be key in understanding the severity of long COVID, a collection of symptoms that last three months or longer after your first COVID symptoms.
The new study, published in the journal Clinical Ophthalmology, showed that the new onset of eye symptoms in people with long COVID may be an indicator of more severe disease.

Researchers from the Yale School of Medicine analyzed survey data from 595 adults who self-reported having long COVID in surveys conducted from May 2022 to October 2023. They found that nearly 60 percent of people reported new-onset of ocular symptoms.
The findings suggest that ocular symptoms in long COVID may be interpreted as vision-related manifestations that cluster with systemic post-COVID conditions. The symptoms include a new onset of :
Notably, individuals with ocular symptoms reported:

Long COVID includes a wide range of symptoms or conditions that may improve, worsen, or be ongoing. While anyone who gets COVID-19 can develop Long COVID, studies have shown that some groups of people are more likely to develop Long COVID than others, including:
While many of the Long COVID conditions remain to be fully recognized, some people have more than one symptom that can be moderate to severe, and also impact the quality of life. According to the US CDC, they include:

A Parliamentary Standing Committee on Health and Family Welfare has raised serious concerns about growing doctor burnout, especially among junior and senior resident doctors, and warned that it is now affecting both doctor well-being and patient safety. Noting that overworked doctors are a risk for patient safety, the panel said that fatigue-driven errors and burnout could compromise care.
To tackle this, the committee recommended that the government introduce and strictly enforce a formal “Clinical Duty Hours Regulation” policy. This should mandate fixed rest periods and monitored duty rosters, with oversight mechanisms to prevent violations, stated the panel in its 172nd report presented before the Parliament.
The recommendation comes amid growing concern over long, unregulated shifts in teaching hospitals, where residents often work extended hours with limited rest.
The panel warned that such conditions not only increase the likelihood of clinical mistakes but also contribute to burnout and mental health stress among young doctors.
The Panel noted that due to persistent human resource shortages, the working hours of junior and senior residents doctors often stretch from 24 to 36 hours. This increases risk of clinical errors and burnout, thereby compromising patient safety. Thus it recommended a mandatory working-hour regulatory framework:
However, it noted the contractual engagement must not substitute regular appointments, as excessive reliance on contractual staff may dilute institutional accountability and continuity.
Instead, the panel has recommended adopting a "Total Support model for medical professionals" to attract and retain qualified doctors and specialists in the public health system.

Burnout is distinct from depression, which influences every aspect of life and often involves persistent thoughts of hopelessness or worthlessness. Burnout typically involves limited manifestations to the work environment, although its impact can resonate into other areas.
Symptoms of Burnout
1. Exhaustion: Prolonged mental and physical depletion of your energy levels.
2. Depersonalization: Cynicism and lack of concern creep into relationships and communication.
3 Reduced Personal Achievement: Your work loses worth, and you may feel you are not up to standards, giving in to frustration and reduced originality.
These signs frequently coincide with physical signs (headaches, muscle pain, sleeplessness), emotional signs (self-doubt, loneliness, unhappiness), and behavioral signs (social withdrawal, outbursts of anger, abandonment of obligations).

Continuing the legacy of football legend Joe Thompson, his wife Chantelle revealed she is pregnant with his baby after IVF treatment using frozen embryos.
Joe Thompson died in 2025 after developing cancer for a third time - beating the illness twice.
But after the former Manchester United star was diagnosed with Hodgkin Lymphoma for a third time, which had spread to his lungs, he died aged 36.
"It just means absolutely everything. I know it's never going to replace Joe obviously. Joe's Joe. But to be able to bring his baby into the world again is beautiful," Chantelle said.
She said Joe had two visions of their family with a baby boy before he died, and he even gave her the name for the baby boy he predicted, and she got pregnant on her first attempt of IVF after he had died.
Egg freezing, also known as oocyte cryopreservation, is an option that has gained significant traction in recent years. It offers women the ability to pause their biological clock and preserve the possibility of having children in the future.
Egg freezing takes a woman's unfertilized eggs from her ovaries and stores them at sub-zero temperatures to be utilized later. It is made to enable women to keep their fertility intact, especially if they are not yet ready to have a baby.
Dr. Pavithra M, Obstetrician, Gynecologist, and Infertility Specialist, told HealthandMe that the workup begins with hormone workup and evaluation of various parameters, such as age, body mass index (BMI), and ovarian reserve.
"On the second day of the menstrual cycle, baseline ultrasound scanning is performed to assess the number of follicles; thereafter, various tests of blood are conducted to assess hormone levels. If a woman's parameters are all normal, then she is administered hormonal injections for about 10-12 days."

It causes ovarian hyperstimulation and multiple mature eggs, monitored through ultrasound scans. A trigger shot is administered once the follicles have reached optimal size to help with final egg maturation. It takes 34-35 hours from the trigger shot, wherein eggs are retrieved by minimally invasive procedures under general anesthesia.
"Using a transvaginal ultrasound probe with a needle, each follicle is punctured, and the follicular fluid is aspirated. The retrieved eggs are then screened for quality before undergoing vitrification—a rapid freezing technique that minimizes ice crystal formation and cellular damage," Dr. Pavithra added. The eggs are then stored in liquid nitrogen tanks for long-term preservation.
While egg freezing is possible at various stages of life, experts recommend doing it at an optimal age -- in the late 20s or early 30s when the eggs are of higher quality-- for better outcomes.
