As kids, we were always encouraged to drink more milk and build strong immunity! In almost every Indian household, milk is a constant item that people regularly buy and consume, whether it is in the form of tea, kheer, or cottage cheese and ghee. Milk, a staple in many diets, comes in various forms, including fermented and non-fermented varieties. Fermented milk products, such as yoghurt and kefir, undergo a process of fermentation, which involves the addition of beneficial bacteria. Non-fermented milk, on the other hand, is milk that has not been fermented.

A recent study published in BMC Medicine showed that there was a potential link between milk consumption and heart disease risk. Now non-fermented milk items include milk, butter or cream, the study found that women who consumed a lot of non-fermented milk were at a higher risk of developing ischemic heart disease and myocardial infarction. However, no such association was observed in men.

Fermented Milk and Heart Health

In contrast to non-fermented milk, fermented milk products have been linked to various health benefits, including improved heart health. A few examples of fermented foods if cheese or Dahi. We all know that the fermentation process increases the levels of probiotics, beneficial bacteria that can positively impact the gut microbiome. A healthy gut microbiome is associated with reduced inflammation, improved insulin sensitivity, and lower blood pressure, all of which are important factors in maintaining heart health.

Role of the Gut Microbiome

The gut microbiome are really important for your digestive system have their own complex ecosystem that helps us keep our guts healthy. Basically, the way it is composed helps us take care of our, including digestion, immune function, and metabolism. Fermented milk products, rich in probiotics, can help maintain a healthy gut microbiome, which may contribute to reduced heart disease risk.

How Does it Work?

While the exact way it works and what is the connection between non-fermented milk and heart disease in women are still being explored, several factors may contribute to this relationship. Further research is needed to fully understand the complex relationship between milk consumption and heart health. However, the findings of this study suggest that individuals, particularly women, may benefit from moderating their intake of non-fermented milk and incorporating more fermented milk products into their diet. These factors include:

Hormonal Differences

Hormonal differences between men and women may influence how the body processes milk components.

Gut Microbiome Composition

Non-fermented milk may have a different impact on the gut microbiome compared to fermented milk.

Inflammatory Markers

Certain components of non-fermented milk may trigger inflammation, which can contribute to heart disease.

As our economy and connectivity evolved, many companies and professionals have moved onto working 24/7. To make this happen, people have come up with shift schedules that will allow some people to work during the day, while others work night shifts. However, an issue people face is that night shifts are unconventional and can impact your health. It changes the way your body functions and can have a severe impact on your body.

A study published on June 16 in ERJ Open Research found that women who consistently work night shifts have a 50% increased risk of moderate to severe asthma compared to women who workday shifts. Interestingly, this connection wasn't observed in men.

Researchers from the University of Manchester in the U.K., explained that while the study doesn't pinpoint why this link exists, it might be due to disruptions in the body's natural clock, which can affect hormone levels.

Hormonal Connections and Increased Risk

The idea that hormones play a role is supported by a key finding: postmenopausal women on the night shift who were not using hormone replacement therapy (HRT) saw their risk of moderate to severe asthma nearly double.

Researchers noted that asthma already affects women more severely than men, leading to higher hospitalization and death rates for women. Previous studies have also linked night shift work to more severe asthma in general. This led the team to investigate if night shifts would further increase asthma risk specifically for women.

Study Details and Findings

The study tracked the health of nearly 275,000 working individuals in the U.K. Biobank, a large health research project. Over 5% of these workers had asthma, with 2% suffering from severe asthma requiring a rescue inhaler.

The results clearly showed that women working only night shifts had 50% higher odds of moderate to severe asthma. This risk jumped to 89% higher for postmenopausal women on the night shift who were not taking HRT.

Researchers suggested that HRT might offer some protection against asthma for night shift workers, but he stressed that more research is needed to confirm this. He also speculated that higher testosterone levels in men might protect them from asthma, as testosterone has previously been linked to asthma protection.

Unanswered Questions and Future Steps

While the study highlights a strong association, it can't definitively prove that night shifts cause asthma in women. Other factors, like the different types of jobs men and women hold on night shifts, could also contribute to the risk.

Experts pointed out that it's often not easy for workers to simply change their shifts. She emphasized the need for further research to fully understand this link and to find ways to reduce the risk for women who work night shifts.

What Are Some Other Long-Term Effects Of Night Shifts?

Shift work, especially at night, seriously disrupts your body's natural 24-hour cycle, called the circadian rhythm, leading to various health challenges. Here are some long-term health issues that may arise from it, according to UCLA health.

Cancer

Disrupted circadian rhythm impacts cell function, DNA repair, and cell death, potentially leading to cancer, as reported by the National Toxicology Program. Reduced melatonin from irregular light/dark exposure hinders cell repair, making cancer progression easier.

Cardiovascular Disease

Working unusual hours increases heart disease and stroke risk. A European Society of Cardiology-linked study found women with five-plus years of rotating night shifts faced higher death risk, tied to stress, high blood pressure, and metabolic factors.

Gastrointestinal Disorders

Shift workers often experience digestive issues like abdominal discomfort, constipation, diarrhea, and IBS. These gut problems stem from sleep deprivation and unhealthy, processed food diets common in shift work, altering gut bacteria.

Mental Health Disorders

Nonstandard hours make maintaining relationships difficult, leading to isolation, stress, depression, and anxiety. A large study in The Lancet Psychiatry found shift work directly linked to higher risks of depression and anxiety, increasing with shift frequency.

Metabolic Disorders

Shift work disrupts circadian rhythm and hormones, raising risks for obesity, metabolic syndrome, and Type 2 diabetes. It's linked to higher BMI, hormonal imbalances affecting appetite/weight, and unhealthy lifestyle choices like smoking and poor diet.

Taking care of a sick person is a taxing job not many people can fullfill. Patients with mental health issues like dementia require specialized care and not everyone is equipped to handle these situations. Many times, people with dementia have emotional outbursts, difficulty communicating as well as doing normal lifestyle activities. Caring for people with dementia requires a team of people, sometimes 24/7 care with rotations for staff, so that the patient is not left unattended for an extended period of time. However, does this extensive routine affect the caregiver’s health? A new study has found concerning future implications for dementia caregivers.

Caring for someone with dementia might put caregivers at higher risk for their own brain aging and future dementia, a new study suggests. This is largely due to certain lifestyle factors.

Caregivers' Hidden Risk

A recent report from the Public Health Center of Excellence on Dementia Caregiving, released on June 12, found that nearly 3 out of 5 dementia caregivers (59%) have at least one risk factor that increases their chances of developing dementia over time. Even more concerning, about 1 in 4 (24%) have two or more of these risk factors.

Matthew Baumgart, senior vice president of health policy for the Alzheimer's Association, called this analysis a "wake-up call." He noted that caregivers are often so focused on their loved ones that they neglect their own health. This highlights a critical need for public health strategies to support these vulnerable individuals.

Key Risk Factors Identified

Researchers analyzed health data from caregivers across 47 states in 2021 and 2022. They found that caregivers were more likely than the average person to have five things that aren't good for brain health:

Smoking

Caregivers were 30% more likely to smoke. Smoking is bad for your overall health, including your brain.

High Blood Pressure

They were 27% more likely to have high blood pressure. High blood pressure can damage blood vessels, including those in the brain.

Poor Sleep

21% more likely to say they didn't sleep well. Not getting enough good sleep can affect how your brain works and ages.

Diabetes

They had a 12% higher chance of having diabetes. Diabetes can lead to problems with blood flow and brain function.

Obesity

Caregivers were 8% more likely to be overweight or obese. Being overweight is linked to many health problems, including some that affect the brain.

Interestingly, there was one good piece of news: caregivers were actually less likely to be inactive (meaning they moved around more) compared to others. This might be because looking after someone with dementia often involves a lot of moving around.

Younger Caregivers Face Greater Vulnerability

This part focuses on younger caregivers, and the news isn't great for them. The study found that younger people who care for someone with dementia are at an even higher risk.

• 40% more likely to have many of these risk factors at once, compared to other people their age.
• 86% more likely to smoke. That's a huge difference!
• 46% more likely to have high blood pressure.
• 29% more likely to get less than six hours of sleep each night compared to their friends who aren't caregivers.

The researchers explained that knowing which groups of caregivers are most at risk, public health officials can better plan and offer help. Instead of a one-size-fits-all approach, they can create specific programs and resources for the groups that need it most.

A parasite that causes malaria is halted by sickle cells and makes people who carry the sickle cell trait more resistant to the disease. This is why sickle cell trait also occurs more in people who live in tropical and sub-tropical regions where cases of malaria were or still is common.

It comes from the copy of an abnormal sickle or the HBB gene and one copy of the normal HBB gene. The gene is an evolutionary response to malaria, where humans begin to develop an abnormal HBB gene and pass it onto to the next generation.

The "Black Disease"

The earliest documentation of sickle cell symptoms in medical texts could be found from the 1870s. However, it had not been formally identified until in 1910. when the first case was detected in the United States. The first case of sickle cell disease or SCD in the US was in 1904, when Walter Clement Noel, a 20-year-old dental student from Grenada, sought care for anemia at Chicago Presbyterian Hospital, where he met Dr James B Herrick. Dr Herrick was a cardiologist and professor of medicine and he was assigned noel who had experienced recurrent episodes of "muscular rheumatism" and "bilious attacks" over a period of 3 years.

This case was assigned to an intern Dr Ernest E Irons by Dr Herrick. Dr Ernest performed initial blood work on Noel and observed the unusual sickle-shaped red blood cells in the sample under the microscope. This is when Dr Herrick was told about it, leading to him publishing the first documented case study of SCD, titled, "Peculiar Elongated and Sickle-Shaped Red Blood Corpuscles in a Case of Severe Anemia."

However, the name, sickle cell anemia, was not coined until in 1922, by Vernon Mason. It was also the first diagnosed genetic disease and the first to be linked to the hemoglobin protein.

But, how did it gain the name "Black Disease"? This is because the disease often disproportionately affected Black Americans in the US, which caused racial bias and prevented people with sickle cell from receiving quality care.

In response to this, in the 1960s, the Black Panther Party worked to expand community-based care for education and treatment of this disease. This was part of their initiative to tackle the sickle cell, which received little to no attention because it mostly affected a large part of Black community.

While Herrick may have described the first known case in the US, SCD did exist for generations in African and Mediterranean descent, due to the regions being prone to diseases like malaria. In African medical literature, it was known as "ogbanjes", which loosely translated into "children who come and go" as the infants born with this disease had a high mortality rates. One of the first records, as is also noted by the Sickle Cell Association from Africa is from a Ghanian family in 1670.

A Groundbreaking Discovery

In 1927, scientists Hahn and Gillespie made a discovery that reshaped our understanding of blood disorders. While studying red blood cells in a low-oxygen environment saturated with carbon dioxide, they observed a curious phenomenon: the cells twisted into sickle shapes—not just in patients with sickle cell disease (SCD), but sometimes in people without any symptoms at all.

This puzzling observation hinted at an invisible carrier state and eventually led to the identification of what we now call the sickle cell trait.

Fast-forward to the late 1940s and early 1950s, and the pieces of the puzzle began falling into place. In 1949, two scientists working continents apart independently uncovered the genetic blueprint of SCD.

Col. E. A. Beet, a military physician stationed in what is now Mozambique, published his findings in an African medical journal. Around the same time, Dr. James V. Neel at the University of Michigan released a parallel study in the journal Science. Both revealed that SCD follows an autosomal recessive inheritance pattern—meaning the disease only occurs when a person inherits two copies of the mutated gene. Those with just one copy? They carried the trait, but not the illness.

Together, their work laid the foundation for our modern understanding of genetic inheritance and reshaped how we screen for and manage sickle cell disorders today.
