New Treatments for Multiple Myeloma

Multiple myeloma is a complex blood cancer characterized by the proliferation of malignant plasma cells within the bone marrow. Recent advancements in treatment have significantly improved patient outcomes, introducing innovative therapies that target the disease more precisely and effectively.

Traditional Treatment Approaches 

 

Historically, multiple myeloma has been managed through a combination of therapies: 

 

Chemotherapy: Utilizes cytotoxic drugs to kill rapidly dividing cancer cells. 

 

Corticosteroids: Help reduce inflammation and directly combat myeloma cells. 

 

Stem Cell Transplantation: Particularly autologous stem cell transplants (ASCT), where a patient's own stem cells are used to restore bone marrow function after high-dose chemotherapy. 

 

Radiation Therapy: Employed to control bone pain and treat localized disease.

Recent Advances in Treatment  

The past decade has witnessed remarkable progress in multiple myeloma treatment, with several novel therapies enhancing patient survival and quality of life: 

 

Proteasome Inhibitors: Drugs like bortezomib and carfilzomib disrupt cancer cell protein degradation, leading to cell death. 

 

Immunomodulatory Agents: Agents such as lenalidomide and pomalidomide modulate the immune system to target myeloma cells. 

 

Monoclonal Antibodies: Daratumumab and elotuzumab are designed to recognize and bind specific proteins on myeloma cells, marking them for destruction by the immune system.

Recent promising developments: 

One notable advancement is the use of Blenrep (belantamab mafodotin), an antibody-drug conjugate targeting the B-cell maturation antigen (BCMA) on myeloma cells. Clinical trials have demonstrated that Blenrep, in combination with standard therapies like bortezomib and dexamethasone, can significantly reduce the risk of disease progression or death in patients with relapsed or refractory multiple myeloma. For instance, a recent study reported a 42% reduction in the risk of death when Blenrep was added to the treatment regimen. 

 

Another promising development is the approval of Elrexfio (elranatamab), a bispecific antibody that engages T-cells to target and destroy myeloma cells. Studies have shown that Elrexfio provides a median overall survival of more than two years in patients with relapsed or refractory multiple myeloma, highlighting its potential as an effective treatment option. 

 

Additionally, CAR T-cell therapies have emerged as a transformative approach in multiple myeloma treatment. These therapies involve modifying a patient's own T-cells to express chimeric antigen receptors (CARs) that specifically target myeloma cells. For example, Carvykti (ciltacabtagene autoleucel) has shown a 45% reduction in the risk of death in clinical studies, offering a one-time treatment alternative to ongoing drug regimens. 

 

These advancements underscore a dynamic shift in multiple myeloma treatment, with ongoing research poised to enhance patient outcomes and quality of life.

Prognosis and Conclusion  

The prognosis for multiple myeloma has improved significantly over the past decade, largely due to these therapeutic advancements. The overall five-year relative survival rate has increased to approximately 61.1%, with even better outcomes expected as new treatments continue to emerge. 

 

In conclusion, the landscape of multiple myeloma treatment is rapidly evolving, with recent developments offering renewed hope for patients. Ongoing research and clinical trials continue to explore innovative therapies and combination strategies, aiming to further improve survival rates and quality of life for those affected by this disease.

What Every Woman Should Know About Heart Failure

Heart failure is a major cause of disability and death in both men and women. Over the last few decades, significant resources have been dedicated to understanding what causes it, and to developing better treatments for it. And significant strides have been made.

One thing that we have discovered is that many aspects of heart failure differ between men and women. For both sexes, heart failure comes about as a result of coronary artery disease, or chronic hypertension (high blood pressure). Usually, the symptoms of heart failure, and the treatment of it, are similar in men and women, but there are some differences. 

 

There are a few aspects of heart failure that pertain especially to women. These include the causes of heart failure in women, the age of women who develop heart failure, the symptoms caused by the heart failure, and how doctors treat heart failure in women. If you’re a woman who has heart failure, you should make sure you know these differences.

Causes of Heart Failure That Are Especially Important in Women 

 

Hypertension The most common medical problems that lead to heart failure are hypertension and coronary artery disease (CAD). Of these, hypertension is the leading cause in both sexes. However, hypertension is substantially more likely to cause heart failure in women than in men. Hypertension increases the risk of developing heart failure by 300% in women, but “only” 200% in men. Among women with heart failure, hypertension is the underlying cause in 59% of cases in women, compared to 39% in men. So while it’s important for anyone with hypertension to be treated adequately, it’s even more so for women. 

 

Diastolic Heart Failure 

In diastolic heart failure, cardiac function deteriorates because the heart muscle becomes stiff, and the heart has difficulty filling with blood. As a result, the amount of blood that is pumped around the body with each beat is significantly reduced (making you tired and exercise intolerant), and the blood that is unable to fill the heart “backs up” into the lungs (producing pulmonary congestion). While this condition can occur in anyone, it’s more prominent in women than men. 

 

Diabetes 

Diabetes by itself doesn’t cause heart failure, but people with diabetes have a high incidence of conditions that do, such as CAD and hypertension. Furthermore, for reasons that are not understood, women with diabetes are twice as likely to develop heart failure than men with diabetes. 

 

Obesity 

Women who are obese have a high risk of developing heart failure that is 50% higher than women who are normal weight. Obese men also have a higher risk of heart failure, but the excess risk from obesity is not thought to be as high in men as it is in women.

Chemotherapy

 Certain drugs used for chemotherapy can cause cardiac toxicity that can lead to heart failure. Women tend to be exposed to these chemotherapy agents a lot more often than men, in particular, for the treatment of breast cancer. 

 

Stress Cardiomyopathy 

Stress cardiomyopathy, also known as “broken heart syndrome,” is a form of sudden, severe heart failure that is triggered by extreme emotional trauma. While this condition can be found in either sex, it’s far more common in women, and may be related to microvascular angina – a condition that is more common in women. 

 

Age of Women with Heart Failure 

Women who develop heart failure usually do so at an older age than men who develop heart failure. Unfortunately, as past clinical trials tended to exclude people over the age of 65, this means that relatively little data has been collected from clinical trials showing how older women with heart disease respond to treatment. Recently, researchers have been including a sufficient number of elderly women in their clinical trials, and this shortcoming is slowly being rectified. 

 

Symptoms of Heart Failure in Women 

As mentioned previously, the symptoms of heart failure in men and women are largely the same – gradually worsening fatigue, dyspnea, exercise intolerance, and edema. However, some scientific studies suggest that women with heart failure are more likely to experience significant dyspnea and edema than men.

 

Response to Treatment in Women

As stated, clinical trials evaluating the treatment of heart failure have tested considerably more men than women. Nevertheless, the data that is available strongly suggests that women with heart failure respond to treatment just as favorably as men. 

 

Differences in How the Hearts of Men and Women Respond to Cardiac Stress 

In studies with animals and in clinical trials, evidence is accumulating to suggest that the heart muscles of men and women react differently to various kinds of physiologic stress. Several animal studies have looked at how the hearts of males and females react to experimental conditions that have been designed to produce heart failure. These studies have consistently shown that female cardiac muscle tends to respond by making various adaptions that help to prevent heart failure, whereas male cardiac muscle fails more quickly. 

 

Clinical trials on people have shown the same thing. In those with aortic stenosis (a narrowing of the aortic valve, which greatly increases the pressure and stress in the left ventricle), premenopausal women develop cardiac hypertrophy (thickening of the heart muscle) more readily than men. This hypertrophy reduces wall stress, delays the onset of dilated cardiomyopathy and thus, reduces the risk of heart failure. Interestingly, postmenopausal women do not show this same adaption, and they develop heart failure at the same rate as men, suggesting that female hormones may play a part. However, clinical trials evaluating this have given contradictory results.

These findings may help to explain why women develop heart failure later than men, and why women who have heart failure tend more often to have diastolic heart failure than men. 

 

Still, having said this, all we can say with confidence at the moment is that the hearts of men and women respond somewhat differently to various kinds of physiological stress. 

 

Outcome of Heart Failure in Women

Evidence suggests that, even though they usually develop heart failure at a later age than men, women with heart failure tend to survive longer than men. 

 

This relatively good news for women who have heart failure is counter-balanced by some clinical evidence that suggests that doctors tend to be less aggressive when treating women with heart failure when compared with men. One reason for this may be that women may tend to minimize their cardiac symptoms when talking to their doctors. Those doctors who do not push their patients for a full accounting of symptoms may not be aware of just how sick their female patients actually are.

 

Therefore, it’s very important for anyone, male or female, who has symptoms of heart failure – especially worsening fatigue or dyspnea – to make sure their doctors are aware of it. But, maybe women need a little extra reminding of how important it is.

What does breast cancer in men look like? Signs and symptoms to watch out for

Breast cancer are prevalent in women, but men can be at risk too

While we're all aware of the breast cancer risks in women, we often neglect the possibilities of breast cancer in men. Although rare, men can also develop cancerous breasts. Clinical evidence suggests that less than 1% of all breast cancers occur in men. About 2,650 men are expected to be diagnosed with breast cancer, and an estimated 530 men are expected to die from it. So, even if the chances are slim, there is no way one should strike out the possibility and should make oneself aware of the signs and symptoms of male breast cancer.

Male breast cancer is most common in older men

According to the Centre for Disease Control and Prevention, "The risk for breast cancer increases with age." Most breast cancers are found after age 50, the health agency suggests. That said, regular breast screenings could be an efficient way to detect any signs of breast cancer risks in men.

Are there any symptoms to watch out for?

There are many signs of breast cancer in men. As per the American Cancer Society (ACS), below are some of the common symptoms of male breast cancer.

- A painless lump in one breast

- Nipple retraction, ulceration, and discharge

- Dimpling of breast

- Discoloration of the breast or nipple skin

While the above mentioned signs are the early warning signs of breast cancer, there are some signs that can tell that the cancer is spreading. Swelling in the lymph nodes, breast pain and bone pain can mean something more serious.

What type of breast cancers can be diagnosed in men and how?

The CDC suggests three types of breast cancer that can be detected and diagnosed in men.

- Invasive ductal carcinoma: This type of breast cancer starts in the ducts and then grows outside the ducts into other parts of the breast tissues.

- Invasive lobular carcinoma: The cancer cells begin in the lobules and then spread to the closely-knitted breast tissues.

- Ductal carcinoma in situ (DCIS): These may lead to invasive breast cancer, since they're only in the lining of the ducts, and have not spread to other breast tissues.

Breast cancers in men and women can be diagnosed with the help of mammogram, ultrasound, a nipple discharge test or a biopsy. Regular self-examination of the breast can also help with diagnosis.

Do genes play a role?

Breast cancer can also be an outcome of genetic mutations. A strong family history of breast cancer can increase a man's risk of developing the same condition. Men who inherit abnormal BRCA1 or BRCA2 genes may have an increased risk of male breast cancer. However, genetic mutations are not the only factor that could lead to breast cancer in men.

Treatment

Depending on the size of the tumour, the doctor is likely to suggest the treatments. Surgery, chemotherapy, radiation therapy, hormone therapy, and targeted therapy are some of available treatments for breast cancer.

 

Everything you need to know about supplements

Everything you need to know about supplements

Food supplements, as the name suggests are added tablets whose purpose is to provide nutrients to the body that are otherwise lacking due to improper diet. It is important to note that a diet should have sufficient nutrients but in case, the recommended amount is not consumed, one can take supplements.

Food supplements come in various forms like tablets, pills, syrups, energy bars as well as a powder, which deliver the nutrients like vitamins, minerals, amino acids, fatty acids and enzymes. Supplements cannot replace a balanced diet and cannot give you all the nutrients that a balanced diet can.

You can buy over the counter supplements but it is advised that you must consult a doctor before starting any supplements. Our body needs only a recommended amount of nutrients every day and if we consume more than the body can handle it can do more harm than good and can even lead to major health conditions.

Benefits of food supplements

People can benefit from food supplements, some of those benefits are:

• Give you proper nutrition that might be lacking due to improper diet
• Many supplements are filled with antioxidants that can reduce the risk of certain diseases like heart disease and certain cancers
• Helps maintain good health
• Supplements can be consumed by athletes to enhance their performance
• It can help you improve cognitive functions
• Increase the efficiency of the immune system
• Some supplements can help improve the quality of sleep
• It can provide added nutrition for pregnant women

Who can take supplements?

If you are a healthy person consuming a balanced diet and you are getting the recommended amount of nutrients, you do not need dietary supplements.

If you fall under any of the following categories you should consult your doctor and discuss a plan for food supplements. The categories are:

• Women who are pregnant or are trying to get pregnant
• Women who are breastfeeding
• Over the age of 50
• Diagnosed with certain deficiencies
• Vegan or vegetarian
• Recently had treatment for obesity
• Restricted from access to certain food items
• Children under the age of 5
• Insufficient sun exposure

How many supplements should you take?

There is a limited amount of nutrients that you need in your body. If you exceed that limit the body flushes out the excess nutrients and in some cases, it can even result in health conditions like nausea, stomach cramps, hair loss, fatigue, diarrhoea and even mild nerve damage.

Risks of excess supplements

You should always consult a doctor before you start taking any supplements because excess nutrients can harm you. Some side effects are:

• Taking vitamin K before surgery can reduce the efficiency of blood thinners causing blood to clot
• Can reduce the effectiveness of certain medicines
• Too many antioxidants can reduce the efficacy of chemotherapy
• Substituting supplements in place of medicines can harm the body
• Vitamin B-6 can lead to nerve damage when used for more than a year at high doses
• Combining vitamin A with retinol-based acne medications can lead to an excess vitamin A
• Excess Vitamin C can cause diarrhoea

How to take supplements properly?

Do’s

• Consult a doctor
• Follow instructions given either by the manufacturer or the doctor
• Take the right supplements for your body
• Be careful if you are on prior medications

Don'ts

• Do not self analyse
• Do not follow the trend, only take supplements your body needs
• Do not consume hormonal supplements without consulting a doctor first

Here's why cold induces tooth pain, hypersensitivity; some remedies for it

A team of researchers from Boston University have uncovered a new function for odontoblasts, the cells that form dentin, the shell beneath the tooth's enamel that encases the soft dental pulp containing nerves and blood vessels.

The results of the study were published in the journal of Science Advances.

"We found that odontoblasts, which support the shape of the tooth, are also responsible for sensing cold," says pathologist Jochen Lennerz, MD, PhD, one of the paper's senior authors and medical director of the Center for Integrated Diagnostics at Massachusetts General Hospital (MGH). "This research contributes a new function to this cell, which is exciting from a basic-science standpoint. But we now also know how to interfere with this cold-sensing function to inhibit dental pain."

Teeth that hurt from exposure to cold can occur for many reasons. Many people have experienced intense pain from cold when they have a hole in a tooth from an untreated cavity, for example. But teeth can also become very sensitive to cold from gum erosion due to aging. Some cancer patients treated with platinum-based chemotherapies have extreme cold sensitivity all over their bodies. "A breeze on the face registers as extreme pain in the teeth, which may even cause some patients to stop therapy," says Lennerz.

Tooth pain has been notoriously difficult to study. A tooth's hardness makes it a challenging tissue to study and inducing tooth pain in humans requires opening the tooth. The team of researchers, therefore, conducted experiments on mice whose molars were drilled under anaesthesia. Mice with dental injuries manifest pain with their behaviour; they drink up to 300 per cent more sugar water than their littermates without dental injuries, for example. In previous research, the team of investigators had discovered TRCP5, a protein encoded by the TRCP5 gene that is expressed in nerves in many parts of the body. Their earlier discovery allowed the researchers to zero in on TRCP5 as a mediator of pain from cold.

By studying genetically altered mice that did not have the TRCP5 gene, the researchers found that the mice with injured teeth did not manifest the increased drinking behaviour and behaved like mice without dental injuries.

"We now have definitive proof that the temperature sensor TRCP5 transmits cold via the odontoblast and triggers nerves to fire, creating pain and cold hypersensitivity," says Lennerz. "This cold sensitivity may be the body's way to protect a damaged tooth from additional injury."

Specifically, in response to cold, the TRCP5 protein opens channels in the membrane of odontoblasts, enabling other molecules, such as calcium, to enter and interact with the cell. If the tooth's pulp is inflamed from a deep cavity, for example, TRCP5 is overabundant, causing increased electrical signaling via the nerves emerging from the root of the tooth and running to the brain, where pain is perceived. When gums recede from ageing, teeth can become hypersensitive because the odontoblasts are sensing cold in a newly exposed region of the tooth. "Most cells and tissues slow their metabolism in the presence of cold, which is why donor organs are put on ice," says Lennerz. "But TRPC5 makes cells more active in cold, and the odontoblasts' ability to sense cold via TRPC5 makes this discovery so exciting."

Lennerz confirmed the presence of the TRPCS protein in extracted human teeth, which was a technical tour de force. "Our teeth aren't meant to be cut into ultra-thin layers so they can be studied under the microscope," says Lennerz, who first had to decalcify the teeth and put them in epoxy resin before slicing them and identifying the TRPC5 channels in the odontoblasts.

The research team also identified a pharmacological target for minimizing tooth sensitivity to cold. For centuries, oil of cloves has been used as a remedy for tooth pain. The active agent in the oil of cloves is eugenol, which happens to block TRCP5. Toothpaste containing eugenol are already on the market, but the findings of this study may lead to more potent applications to treat teeth that are hypersensitive to cold. And there may be novel applications for eugenol, such as treating patients systemically for extreme cold sensitivity from chemotherapy. "I'm excited to see how other researchers will apply our findings," says Lennerz.
