A recent study suggests that people who donate blood regularly may have genetic changes in their blood that could in fact reduce the risk of developing cancer. It is conducted by the researchers at the Francis Crick Institute, and the study has now provided new insights into how and why blood cancers develop. The study is published in the journal Blood and was conducted by the scientists from Heidelberg and the German Red Cross blood donation center. There is yet a need for further research to confirm these findings.
The researchers examined the blood of two groups of healthy male donors in their 60s:
The goal was to analyze genetic mutations in their blood and assess whether frequent donation had any impact on their genetic makeup.
As and when people age, their blood and other cells naturally develop mutations and some of them can also increase the risk of cancer. When anyone donates blood, his or her body compensates by producing new blood cells, which can influence the genetic diversity of stem cells in the bone marrow. The study also found that both groups had a similar number of mutations. For instance the frequent donors had 217 mutations, while the irregular donors had 212 mutations.
However, the nature of these mutations differed. In the frequent donors, 50% of the mutations were of a type not associated with a high risk of blood cancers, compared to only 30% in the irregular donors.
Further laboratory analysis showed that these specific mutations behaved differently from those linked to leukemia, a type of blood cancer. When human blood stem cells with these mutations were injected into mice, they were found to be highly effective at producing red blood cells, which is considered a positive outcome.
Dr. Hector Huerga Encabo, one of the study authors, emphasized that these mutations do not indicate an increased risk of leukemia. The findings suggest that regular blood donation may influence how stem cells evolve, but whether this translates into a lower cancer risk remains uncertain.

One notable disadvantage is the "healthy-donor effect"—because blood donors are often healthier than the general population, their lower cancer risk could be unrelated to blood donation.
Dominique Bonnet, senior researcher and head of a stem-cell laboratory at the Francis Crick Institute, stressed the need for larger studies with female volunteers to confirm the findings.
Despite ongoing research into potential health benefits for donors, the primary goal of blood donation remains saving lives. NHS Blood and Transplant emphasized that while the study is interesting, further research is required to draw firm conclusions. The organization also noted that blood supplies are currently critically low and encouraged eligible individuals to donate.

For decades, melasma treatment began and ended with a tube of cream. The typical first treatment for those stubborn brown-grey patches on the forehead, upper lip and cheeks that are typically caused by sun exposure, hormones or pregnancy was once hydroquinone, retinoid and steroid combinations.
Patients would put some cream on for months, and get some improvement, and then when they stopped, the pigmentation would reappear. Today, these creams have still got a role but dermatology has come a long way and now, patients have so much more to work with, acting on the melasma from different angles at the same time.
There are more choices available within the realm of creams. Gentler brightening agents like thiamidol and 2-MNG have been developed to do the same job as hydroquinone, but they do it in a different way in the body.
Initial studies indicate that these ingredients can be as effective as older favourites, irritating less than older ingredients that are already doing their job of irritating sensitive skin prone to developing melasma in the first place.
Another compound, malassezin, has shown promising early results in that it has been found to inhibit the process of pigment production itself. Due to the chronic and relapsing nature of melasma, dermatologists are more inclined to use these less aggressive, but more tolerated long term maintenance treatments as opposed to short term treatments alone.

The most obvious change in how the skin is treated for melasma is the way of lasers and light-based treatments. A side advantage of the low-fluence picosecond lasers is that they break up excess pigment with very short, gentle energy pulses, meaning that there's less skin damage as a side effect, which is a drawback of older, more aggressive laser settings.
Fractional lasers are now also employed in conjunction with topical treatments to enhance drug delivery into the skin, essentially combining the two treatments. They are regarded as non-invasive technologies since they do not involve any incisions or extended downtime and most patients are able to return to their pre surgery routine within a day or two.
Chemical Peels are also available in a re-optimized formulation for the skin that tends to melasma. Newer types of combination peels use lesser amounts of various active ingredients and less of a single strong acid, reducing the chances for additional pigmentation, which is a common worry in dark skin tones.
They are now more frequently prescribed with topicals and lasers as part of a multi-pronged approach, rather than as a treatment on their own, as they are done in a series of milder sessions.

The technology of microneedling has also come a long way. This once again basic but now formulated with serums and even exosome-based formulations is an area that calms inflammation and helps to regulate the pigments of the skin as it recovers.
This "angle" is called "regenerative" because newer treatments aren't just intended to lighten or fade existing skin melanin, but seek to address the skin's environment that is causing melasma to reappear.
Non-invasive is more than just procedures performed in the clinic. In recent years, low doses of tranexamic acid taken orally under medical supervision has been added to the melasma tool box.
It is internally active, in that it slows blood flow in the blood vessels, which is now known to help trigger the production of pigment in the skin, and is therefore a valuable addition to the treatment of melasma, particularly when other topical treatments are not effective.
There's one thing that sets the tone for the ever-changing landscape of melasma treatment: there's no single answer. It is now known that melasma is a real multi-faceted skin problem that is influenced by multiple factors such as genetics, hormones, sun exposure, heat and inflammation.
Many dermatologists prefer to use a multi-layered approach to skin care for treatment, such as a topical therapy, an in-office procedure and, if applicable, oral skin care therapy, depending on the skin type and pigmentation of the patient. That's not only for quicker results, it also helps to reduce the likelihood of the skin darkening more after treatment, which is more common in patients with darker skin tones.
Today, instead of a one-and-done, dermatologists are more apt to craft a gradual approach that involves calming active pigmentation, then moving to a maintenance regimen that is lighter to avoid pigment re-flash.
“As it is a multi-factorial disease, using any one modality is always going to be limited and a multi-modal approach that combines topical, procedural and sometimes systemic treatment, is what is helping us achieve more lasting results and reduced relapse rates,” says Dr. Ajay Rana.
Despite such innovation, one thing is true: sun protection is a must. If they're going to hold up, it's going to be because of the broad-spectrum sunscreen and the consistent application of it, along with physical protection such as sun hats.
If not, the most sophisticated of the procedures will eventually be replaced by renewed pigmentation.
Although it's a challenging condition to treat, melasma is not a quick fix. However, today there are more ways for patients to visibly improve, and even more of them are not invasive, and have less side effects than five years ago.
If you've used a cream before and stopped using it, it might be worth talking to a dermatologist again; the treatment options are quite different now.

Fatty liver and liver damage are not identical. While fatty liver refers to a buildup of excess fat inside the liver cells, liver damage describes harm caused to the liver due to inflammation, scarring, toxins, infections, or any long-term disease.
The liver turns fatty, when the body stores too much fat in the liver. This can be caused due to obesity, insulin resistance, type 2 diabetes, high cholesterol- referred to as MASLD (Metabolic dysfunction associated Liver Disease). High consumption of alcohol or chronic hepatitis infection can also lead to fatty liver.
In many cases, fatty liver causes no obvious symptoms, especially in the early stages. Some people may feel tired or notice discomfort in the upper right side of the abdomen, but many often know about it incidentally- either during blood tests or through an ultrasound scan.
Liver damage, on the other hand, can range from mild irritation to severe and permanent injury. The damage may be caused by viral hepatitis, alcohol misuse, certain types of medicines, autoimmune diseases, inherited conditions, or fatty liver that has turned serious.
Liver damage may be referred to inflammation, liver-cell injury, fibrosis, cirrhosis, or a reduction in the function of the liver. In short, fatty liver is one condition, while liver damage points to a wider range of liver diseases.

The relationship between the two is important. Fatty liver does not always mean that the liver is badly damaged. Certain people have a simple fatty liver, where fat is present but there are little or no inflammation or scarring in the liver. This stage often improve with weight loss, a healthy diet, exercise, and a reduction in alcohol intake, if alcohol is a factor. However, in some people, fatty liver can progress.
When this fat buildup causes liver swelling and cell damage, it is called MASH (Metabolic Dysfunction-Associated Steatohepatitis) which can lead to an injury and the formation of scar tissue in the liver. Over a period of time, this can progress to fibrosis and, in advanced cases, cirrhosis. At this stage, the liver is damaged and may not be in a position to function properly.
Symptoms also differ. Early fatty liver is often silent. More serious liver damage may cause jaundice, swelling in the legs or abdomen, easy bruising, severe fatigue, confusion, itching, or dark urine. These symptoms suggest the liver is under undue stress and needs proper medical management.

Doctors diagnose these conditions by taking note of the medical history, getting blood tests done, scans, and sometimes specialized tests or even a liver biopsy. Blood tests will show any signs of liver inflammation or liver dysfunction, whereas scans will reveal the presence of fat or scars on the liver.
The key message is this: fatty liver is not always severe liver damage, but it can damage the liver if left ignored. The earlier it is diagnosed, the better is the chance of stopping or reversing the problem. Healthy weight management, regular exercise, balanced nutrition, control of diabetes and cholesterol, and abstinence of alcohol are the important protective steps.
If someone has ongoing fatigue, yellowing of the skin, abdominal swelling, or abnormal liver tests, they consult a doctor at the earliest. Early attention can make a major difference in protecting long-term liver health.

The process of becoming parents is one of hopes, anxieties, and numerous waits for many couples. Infertility does not only refer to a medical problem but is a psychological and sociological problem that can influence relationships, confidence, and overall psychological state of an individual. The World Health Organization states that about one out of six individuals experience infertility at some point in life.
Infertility cannot be considered a problem for women only from the perspective of obstetrics and gynaecology. Infertility problems in women can be associated with ovulatory disorders, PCOS, endometriosis, blocked fallopian tubes, fibroids, decreased ovarian reserve, or declining quality of eggs due to the advanced age of the woman.
In men, infertility may relate to low sperm count, impaired sperm mobility or morphology. Correct diagnosis is the key point of developing the appropriate treatment program.

With the emergence of in-vitro fertilization, known as IVF, people can now have children even if they do not possess the ability to conceive through natural means.
This technique is achieved through stimulation of ovaries, egg collection, fertilizing collected eggs using sperm in laboratory conditions, and implantation of a healthy embryo into the womb. Nonetheless, this method is not a simple one-time process but rather a medically guided journey. Every treatment is based on individual factors of the woman.
Embryology in the modern age has revolutionized the results of IVF procedures. Embryo selection can be done through procedures like ICSI, blastocyst culture, grading of embryos, cryopreservation and, in some cases, genetic screening to select healthier embryos.
ICSI is especially helpful in the case of male infertility, in which a single sperm is introduced into an egg.
The purpose of IVF is not just conception but the creation of a successful and safe pregnancy. In the past, many embryos were used to increase the chances of conception, but that caused complications with either twins or triplets. But now, because of better screening, fewer embryos can be transferred where appropriate, thus decreasing pregnancy risk. According to CDC figures, 37.5% of ART cycles ended in live-birth delivery.
The advances in IVF and embryology have revolutionized fertility treatments into an arena of hope and possibilities. With proper counselling, couples can embark upon their fertility journey with certainty. Being parents was once the dream of many people; however, with the advancements in the scientific field, science is now enabling many couples to fulfill this dream.
