PCOS affects a major part of a menstruating person’s life than many of them are aware of. The lack of information about the condition and the reluctance of people to talk about the matter makes it worse. As we kick off World PCOS Awareness Month, we try to understand the proper repercussions and the best ways to manage your periods. As science progresses each day, many women have taken the initiative to further the research on PCOS and the reproductive health of women. We spoke to Dr Prarthana Shah, a doctor who specialised in preventative CVD medicine and an Integrative Health Coach to get a better understanding of the vital role nutrition plays in a woman’s reproductive cycle.

Polycystic Ovary Syndrome (PCOS) is a hormonal disorder affecting millions of women worldwide. Characterized by irregular menstrual cycles, excess androgen production, and the presence of cysts on the ovaries, PCOS can lead to a range of health issues, including infertility, obesity, type 2 diabetes, cardiovascular disease, and endometrial cancer.

Role of Nutrition in PCOS Management

A balanced diet plays a crucial role in managing PCOS symptoms and reducing the risk of associated health complications. By focusing on nutrient-dense foods and avoiding certain triggers, women with PCOS can significantly improve their overall well-being.

According to Dr. Prarthana, “The first thing is B12. So, a common deficiency, even otherwise, which can affect a woman's hormonal balance, because it helps regulate your hair length, and so it's important to make sure that you're getting enough B12.” There are important nutrients that women must have for healthy menstrual cycles.

• Vitamin B12: Essential for hormonal balance, hair health, and regular menstruation.
• Vitamin D: Helps regulate hormones, supports ovarian function, and improves insulin sensitivity.
• Iron: Crucial for preventing anaemia, which is common during menstruation.
• Electrolytes: Help maintain fluid balance and prevent fatigue.
• Amino acids: Provide building blocks for proteins and support overall health.

Dietary Recommendations for PCOS

As Dr Prarthana mentioned, the key nutrients that women lack are the reason why their periods might be irregular and make it difficult for them to handle it. She suggested that it's essential to prioritize a nutrient-rich diet. Focus on consuming whole foods like fruits, vegetables, whole grains, lean proteins, and healthy fats.

Minimize your intake of processed foods, sugary drinks, processed meats, and refined carbohydrates, as these can contribute to inflammation and hormonal imbalances. Consider limiting or avoiding dairy products, as they may contain hormones that can disrupt your hormonal regulation.

She also emphasised the importance of seasonal fruits. While many people have expressed their reservations with cross-contamination and germs from fruits she says, “You have to eat seasonal fruits and vegetables. Greens and salad leaves, all of these things for vitamin B12. Now, of course, there will be some vendors that cut it up. So, don't buy it from there. one tip I personally suggest is that I use something called Veggie Wash where I wash my salad leaves in that at home. You can also wash it with salt or apple cider vinegar.”

When enjoying seasonal fruits and vegetables, be mindful of potential contamination from vendors who cut and sell them. Wash them thoroughly at home to ensure safety. Finally, stay hydrated by drinking plenty of water throughout the day to support overall health and prevent dehydration.

Lifestyle changes you should make for PCOS

According to Dr Prarthana, your lifestyle plays a really important role in PCOS, “So, I know most women, even though they regularly exercise, I mean the ones that do, also kind of skip it during the period and that is the wrong thing to do, ideally.”

She also expresses how much it actually helps with period pains and relief for women, “It's okay. You should go and do some sort of exercise. Go for a walk. It could be lighter if you're, you know, tired. But something in some form of movement, maybe yoga, stretching, whatever works for each person depending on how much pain they have. It really opens up the muscles and gives you relief.”

Other changes include,

• Manage stress: Practice stress-reduction techniques like meditation, yoga, or deep breathing.
• Prioritize sleep: Aim for 7-8 hours of quality sleep each night.
• Consider supplements: Consult with a healthcare professional about potential supplements, such as vitamin D and iron, to address specific deficiencies.

Squirrels could be natural hosts of the mpox virus (MPXV) -- that causes monkeypox disease -- according to a recent study by German researchers.

The team from the Helmholtz Institute for One Health (HIOH) identified the fire-footed rope squirrel (Funisciurus pyrropus) as a likely natural reservoir of the MPXV.

The study published in the journal Nature revealed that sooty mangabeys – a primate found in West Africa -- can contract mpox by eating infected squirrels. The disease may present mild lesions, but it can also cause more severe skin lesions or even be fatal.

"Identifying the animal sources of the virus and the exposure routes that lead to inter-species transmission are key steps towards understanding spillover mechanisms and developing effective prevention measures to mitigate the risk of transmission to humans," said Livia V. Patrono, one of the senior authors at HIOH.

Squirrels Suspected MPXV Hosts

While squirrels have long been suspected as potential reservoirs for MPXV, their role was confirmed after an investigation of an mpox outbreak among wild sooty mangabeys (Cercocebus atys) in Côte d'Ivoire.

During the outbreak, reported in early 2023, nearly one-third of the primates showed clinical signs of disease, and four infants died.

The team conducted viral genome sequencing and found that the infected monkeys carried a virus that was nearly identical to an MPXV strain identified in a fire-footed rope squirrel found dead 12 weeks earlier nearby.

Further, the team analyzed fecal samples from the mangabeys. A sample collected eight weeks before the outbreak's onset contained DNA from both the virus and the rope squirrel. This provided strong evidence of interspecies transmission at that moment.

Sooty mangabeys have been previously observed catching and eating fire-footed rope squirrels, which provide a direct route for the transmission of viruses.

Mpox Continues To Spread Globally

Although mpox is no longer a public health emergency, outbreaks of clade I and clade II strains of the mpox virus are continuing in many countries around the world, especially in Africa.

Last week, Madagascar announced the country's first death from mpox, a 3-year-old girl from the island nation’s eastern city of Toamasina.

The WHO has also confirmed that two cases of the recombinant strain – combining genomic elements of clades Ib and IIb of the monkeypox virus (MPXV) – have been identified to date: one in the United Kingdom and one in India.

Mpox is an infectious disease caused by the monkeypox virus (MPXV), part of the Orthopoxvirus genus, which also includes the virus that causes smallpox.

It spreads through close physical contact, including sexual contact, and in some cases through contaminated materials or respiratory droplets.

Symptoms typically include fever, swollen lymph nodes, rash, and/or lesions.

The global health body has also urged all countries to “remain alert to the possibility of MPXV genetic recombination.” It has also urged for continued epidemiological surveillance, sequencing, vaccination of at-risk groups, and infection prevention and control measures.

An international group of scientists has created an artificial intelligence tool that can estimate a woman’s likelihood of developing breast cancer within the next four years.

The AI tool, known as the BRAIx risk score, analyzes mammogram images to generate an individualized risk assessment and flag women who may face a higher chance of developing the disease.

It may not only show the current risk but also predict the future risk, enabling early detection and treatments for a better outcome.

According to the findings published in The Lancet Digital Health journal, nearly one in 10 women ranked in the top 2 percent of risk by the AI tool were diagnosed with breast cancer within four years. This was despite previously receiving a clear screening result.

“These risk scores enable future development of personalized screening pathways to transform population breast cancer screening and save lives,” said corresponding author Helen M. L. Frazer of the University of Melbourne.

Frazer noted that identifying women who appear cancer-free but carry very high risk -- comparable to those with inherited BRCA1 or BRCA2 mutations -- will unravel both hereditary and non-hereditary causes of breast cancer.

From one-size-fits-all screening to personalization

Breast cancer screening programs have significantly lowered mortality rates -- by roughly 40-50 percent among women aged 50 to 74. However, most screening systems still apply the same approach to all women, regardless of individual risk.

Traditional screening tools use genetics, breast density, and questionnaires to estimate breast cancer risk. On the other hand, new AI-based screening tools, such as BRAIx personalizes screening by gathering information already present in breast scan images to better identify who is at higher risk.

“Our results show that conventional mammographic density is a far weaker predictor of breast cancer risk than the BRAIx risk score, even for interval cancers,” the researchers said in the paper. Interval cancers are aggressive tumors diagnosed after a negative mammogram.

The BRAIx Tool

The BRAIx risk score was developed using mammograms from nearly 400,000 women. To prove its efficacy, the AI tool was tested on data from almost 96,000 women from Australia and then confirmed in an independent Swedish population of over 4,500 women.

The findings showed that:

• The BRAIx risk score estimated breast cancer risk more accurately than the traditional risk factors, such as breast density, country of birth, and even family history.

• For the top 2 percent of women with the highest BRAIx risk score, the probability of a cancer diagnosis within 4 years was 9.7 percent -- a risk level exceeding that typically seen in women with inherited BRCA1 or BRCA2 mutations.

The BRAIx risk score can:

• Make breast screening more personalised,
• Improve early cancer detection,
• Reduce false alarms,
• Save lives without increasing costs

Global Breast Cancer Burden

Breast cancer continues to be the most common cancer among women worldwide.

A recent study published in The Lancet Oncology journal predicted that the number of new cases of the deadly disease will reach more than 3.5 million globally in 2050 -- rising by a third from 2.3 million in 2023.

Annual deaths from the disease will also rise by 44 percent -- from around 764,000 to 1.4 million.

However, not smoking, getting sufficient physical activity, lowering red meat consumption, and having a healthy weight can help prevent over a quarter of healthy years lost to illness and premature death from breast cancer.

People who survived a COVID-19 infection can be at significant risk for kidney disease, acute kidney injury, and chronic kidney disease. compared to individuals who were not infected, according to a study.

The study, published online in the journal Communications Medicine, revealed that COVID patients have

• a 2.3-times higher risk of acute kidney injury
• a 1.4-times higher risk of chronic kidney disease
• a 4.7 times higher risk of kidney failure

“While we’re in the post-pandemic era, this shows that COVID-19 history is an important variable when considering the long-term impact of the infection on kidney function and disease,” said first author Yue Zhang, who was at Pennsylvania State University, US, while conducting the study. Zhang is currently a postdoctoral scholar at Johns Hopkins Bloomberg School of Public Health.

How Was The Study Conducted?

For the study, data on over 3 million working-age adults in the United States were analyzed.

The team compared the effect of influenza, another common viral infection that affects kidney health, and people with a history of COVID infection on kidney infections.

Using a machine learning model, the individuals were followed between 180 and 540 days for the emergence of new acute or sudden kidney disease.

The results showed that:

• Both COVID and the flu can worsen kidney health
• Flu caused a mild and temporary effect
• COVID increased the risk of acute kidney injury for a longer duration
• COVID survivors developed kidney disease within a few hours to a few days
• COVID patients had a longer-term chronic and end-stage kidney disease.

How COVID Worsens Kidneys Health

The Penn State researchers explained that kidney cells express high levels of the primary protein receptors that SARS-CoV-2 uses to enter and infect cells. Kidney cells also produce specialized enzymes that help viruses enter cells.

According to Kidney Health Australia, an acute COVID infection can impact the kidneys with fevers and respiratory symptoms, and/or worsening blood sugar control.

The US National Institutes of Health stated that renal dysfunction is an increasing clinical indicator of COVID propagation.

Citing several studies, the NIH said that the most common clinical manifestation is proteinuria -- found in more than half of the COVID patients. In addition, hematuria, elevated blood urea nitrogen, and elevated serum creatinine are other common features in Covid survivors with poor kidney health.

Nasr Ghahramani, Professor of Medicine at Penn State College of Medicine, stressed the need for COVID survivors, especially those with diabetes and high blood pressure, to take "more frequent and more prolonged monitoring of their kidney function" to enable early detection and better outcomes.
