On Thursday, Uganda confirmed an outbreak of the Ebola virus in its capital city Kampala, with the first confirmed patient dying from it a day before. As per the new developments, the officials are now preparing to deploy a trial vaccine to put an end to this outbreak.

Groups of scientists are working on the vaccine and deployment of more than 2,000 doses of a candidate vaccine against the Sudan strain of Ebola has been planned and confirmed by the Uganda Virus Research Institute. As per the World Health Organization (WHO), Uganda has access to 2,169 doses of trial vaccine. For now, however, there are no approved vaccines for the strain and officials are still investigating the source of the outbreak.

The WHO had also allocated $1 million from its contingency fund for emergencies to support quick action and contain the outbreak in the country.

Confirmed Case

On Wednesday, the Sudan strain of Ebola killed a nurse employed at Kampala's main referral hospital. It is after his death that Ebola was declared an outbreak in the country. Post-mortem samples too have confirmed the Sudan Ebola Virus Disease and at least 44 contacts of the deceased man have been listed for tracing. 30 of these are health workers.

Ebola is a highly infectious hemorrhagic fever, which is transmitted through contact with bodily fluids and tissue. Symptoms include headache, vomiting of blood, muscle pains and bleeding.

it was in the late 2022, when Uganda had last suffered an Ebola outbreak. It killed 55 of the 143 people who were infected and was declared over on January 11, 2023.

What Is Ebola Virus Disease?

As per the WHO, Ebola virus disease (EVD) is a rare but severe illness in humans and is often fatal. People can get infected with the virus if they touch an infected animal when preparing food, or touch body fluids of an infected person such as saliva, urine, faeces or semen, or things that have body fluids of an infected person like clothes or sheets.

How Does Transmission Work?

Ebola enters the body through cuts in the skin or when one is touching their eyes, nose or mouth. Early symptoms include fever, fatigue and headache.

It was first discovered in 1976 in two simultaneous outbreak, when in Nzara, South Sudan and other in Yambuku, Democratic Republic of Congo. The latter occurred near a village near the Ebola River, which is where it gets its name from.

It is highly infectious and transmissible disease, in fact, there have been cases of health-care workers who have frequently been infected while treating patients with suspected or confirmed Ebola. This occurs through close contact with patients when infection control precautions are not practiced strictly.

Cases of people conducted burial ceremonies, involving direct contact with the body of the deceased too can lead to the transmission of Ebola. Even after the long suffering and recovery, there is a possibility of sexual transmission. Pregnant women who get acute Ebola and recover may still carry the virus in their breastmilk, or in pregnancy related fluids and tissues.

Symptoms:

• feeling tired
• headache
• muscle and joint pain
• eye pain and vision problems
• weight gain
• belly pain and loss of appetite
• hair loss and skin problems
• trouble sleeping
• memory loss
• hearing loss
• depression and anxiety

Fighting cancer is “brutal and unrelenting,” said White House Chief of Staff Susie Wiles, who is now cancer-free after undergoing treatment for early-stage breast cancer.

In an op-ed published Sunday in USA Today, Wiles described undergoing chemotherapy while continuing to lead the White House staff for President Donald Trump.

She said some days, simply getting out of bed and going to work took all her strength. The disease, treatment, test results and uncertainty about what came next occupied her thoughts from the moment she woke up and sometimes even while she slept.

‘Even The Strongest Mind Can Be Overtaken’

“Even the strongest mind can be overtaken by it. At times, mine was,” Wiles wrote.

“Fighting for your health while remaining fully committed to your work can feel impossible,” she said, adding that determination and “perhaps some measure of mind over matter” helped her maintain that balance.

Wiles acknowledged that continuing to work during cancer treatment may not be possible or right for everyone. For her, she said, work provided “a mission larger than myself.”

“Maintaining that balance was not easy,” Wiles wrote, saying the experience gave her “profound respect and empathy” for everyone undergoing cancer treatment.

“It drains you physically, mentally, emotionally and spiritually,” she added.

Wiles said cancer can shrink a person’s world to chemotherapy appointments, blood tests, scans, medications and side effects.

“There is a temptation to measure each day by how sick you feel,” she wrote. She said she worked hard not to let breast cancer become the center of everything.

“I directed as much of my energy as I could toward doing my job,” Wiles wrote. “People depended on me to be strong and clear-eyed, and I was determined not to let them down.”

Her Team Helped Carry The Burden

Wiles said cancer affected her stamina, mobility and focus, making the support of her colleagues crucial.

“People stepped forward without hesitation, filled every gap, carried additional weight and never allowed me to feel that I was carrying this burden alone. I will never be able to repay them,” she wrote.

She also credited her family and two daughters, who “traveled every step of this road with me.”

After surgery, pathology showed no residual cancer. Wiles announced on September 16 that she was cancer-free after receiving clear pathology results at the Mayo Clinic. She had disclosed her early-stage breast cancer diagnosis in March.

She said chemotherapy tested her in ways she could never have anticipated. Her next stage, she added, will involve rebuilding what treatment took from her.

“Cancer does not have to take away who you are,” she wrote.

Wiles Thanks Trump And Her Family

Wiles thanked Trump “for the kindness and compassion” he showed while she was undergoing treatment.

Trump had publicly praised Wiles during her cancer battle, saying in a prerecorded message in May that she was winning her fight.

Wiles also credited her family, friends, colleagues and doctors for helping her through the ordeal.

In a post on X, she said she rarely writes about herself but wanted to share what it was like to fight cancer while continuing to do a job she loves.

“Cancer tried to make my world smaller. I was determined not to let it,” she wrote. She said she hoped her account could offer strength to someone still fighting the disease.

For years, people with type 2 diabetes who needed insulin had to administer an injection daily. Eli Lilly’s newly approved insulin is set to bring a dramatic reduction in that burden from roughly 365 injections a year to just 52.

The US Food and Drug Administration (FDA) has approved Onswik (insulin efsitora alfa-gobe), a once-weekly basal insulin for adults with type 2 diabetes. It is designed to provide a steady level of insulin over seven days and is used alongside diet and exercise to control blood sugar. Find out how different weekly insulin is from the daily shots that patients are used to?

Lilly's Once-Weekly Insulin Gets FDA Approval

Insulin is a hormone that helps glucose move from the bloodstream into cells, where it can be used for energy. It also helps reduce the amount of glucose produced by the liver. People with type 2 diabetes may eventually need insulin when their bodies do not produce enough of it or cannot use it effectively.

Basal insulin is long-acting insulin designed to work in the background throughout the day and night, helping keep blood sugar levels under control between meals and overnight.

Until now, commonly used basal insulins like insulin glargine and insulin degludec have generally required daily injections.

Onswik is a long-acting insulin analogue designed to remain active for an entire week. Instead of injecting a smaller amount every day, patients receive one subcutaneous injection on the same day each week. That could reduce the number of basal insulin injections by more than 300 a year compared with daily treatment.

For someone who finds daily injections difficult to maintain, that development could be gamechanging.

Comparison Between Weekly Insulin & Daily Insulin

Lilly's late-stage QWINT programme included more than 3,400 adults with type 2 diabetes across four Phase 3 studies. Onswik met its primary goal in each study, reducing HbA1c, a measure of average blood sugar over time, by an amount that was not inferior to daily basal insulin.

The studies included people who had never previously used insulin as well as people already receiving insulin treatment.

So the significance of the approval is not that weekly insulin necessarily works better than daily insulin. Rather, it offers comparable blood-sugar control with far fewer injections.

Taking insulin every day can become another task in an already demanding diabetes care routine. Missed or delayed doses can make blood sugar management more difficult. A weekly option could simplify treatment for some patients and potentially make it easier to stay consistent. But convenience does not mean the treatment becomes risk-free.

What Are The Risks & Who Can Take It?

The most important risk remains hypoglycaemia, or dangerously low blood sugar, which is a known risk with insulin.

Severe hypoglycaemia can cause confusion, seizures, loss of consciousness and, in serious cases, death.

Other reported adverse effects of Onswik include allergic reactions, injection-site reactions, changes in fat tissue at injection sites, itching, rash, swelling and weight gain.

The FDA also warns about medication errors and accidental overdose, low potassium levels and fluid retention or heart failure when the medicine is used with certain other drugs.

The FDA approval is specifically for adults with type 2 diabetes. Onswik is not recommended for people with type 1 diabetes due to the risk of severe hypoglycaemia. It is also not a replacement for other aspects of diabetes management.

A new study has identified 485 chemicals used in pesticide products in the US that are linked to breast cancer, raising new concerns about how these chemicals are assessed for safety against serious diseases.

The peer-reviewed research, published in Environmental Health Perspectives, dug beyond the active ingredients in pesticides and examined the inactive ingredients that are often not subjected to the same level of safety scrutiny.

The study identifies chemicals associated with breast cancer risk. It does not establish that exposure to these pesticides causes breast cancer in people.

What Did The Researchers Find?

Of the 485 chemicals identified in pesticide formulations, only 145 were registered with the US Environmental Protection Agency (EPA) as active ingredients. The remaining chemicals were classified as inactive or 'inert' ingredients. These ingredients can serve different purposes, like helping pesticide ingredients spread, penetrate surfaces or become more absorbed.

The researchers argue that focusing primarily on active ingredients may overlook risks from the complete pesticide formulation.

“Our findings highlight a regulatory blind spot around so-called inert ingredients,” lead author Dr Jennifer Kay of the Silent Spring Institute said in a research release.

What Does “Inert” Mean?

An inert ingredient is generally considered 'inactive' as it does not target the pest the product is designed to kill. It does not mean that it has no biological effect on humans. According to the study's researchers, people are exposed to the entire pesticide formulation, not just the active ingredient in the pesticide.

The researchers identified around 4,000 inert ingredients approved for use by the EPA, including some PFAS, commonly known as 'forever chemicals.'

Pesticide Exposure

Pesticide exposure is not limited to agricultural workers or people living near farms. The chemicals identified in the study can also occur in products used around homes, including lawn treatments, flea and tick products and lice treatments. Pesticides can also enter the environment through food and drinking water.

The researchers found that 84 of the identified chemicals were detectable in the general US population based on data from the National Health and Nutrition Examination Survey, although they said this likely underestimates exposure because many of the compounds are not routinely tracked.

Pesticides & Breast Cancer Link

The researchers classified chemicals based on existing evidence linking them to breast cancer. That is different from demonstrating that pesticide exposure directly causes breast cancer in humans.

Breast cancer is a complex disease that involves multiple genetic, hormonal, environmental and lifestyle factors.

The study does, however, raise a question about whether the combined exposure to multiple chemicals is adequately considered during pesticide safety assessments.

The researchers noted that the EPA generally evaluates individual pesticide ingredients rather than the entire formulation or people's exposure to multiple pesticides.

The research comes as breast cancer rates, including among younger women, continue to rise in the US. According to the American Cancer Society data cited by The Guardian, breast cancer incidence has been increasing by about 1% a year, with a slightly faster increase among women under 50.
