How to get vaccines to remote areas? In Sierra Leone they’re delivered by foot, boat or motorbike

Retrieved on: 
Thursday, April 18, 2024

In Sierra Leone almost 59% of the population live in remote, rural areas.

Key Points: 
  • In Sierra Leone almost 59% of the population live in remote, rural areas.
  • Roads may be non-existent or in bad condition, making it very difficult for rural dwellers to access healthcare.

Why are vaccination rates low in Sierra Leone?

  • In stark contrast, only 15% of people had been vaccinated in low-income countries.
  • The hardships Sierra Leoneans face are typical of the obstacles people in low-income countries have to overcome to access healthcare.
  • In the early days of the COVID-19 vaccination campaign in Sierra Leone, it took the average Sierra Leonean living in a rural community three-and-a-half hours each way to the nearest vaccination centre.

How did this vaccine drive tackle the problem?

  • The primary aim of this intervention was to take vaccine doses and nurses to administer vaccines to remote, rural communities, preceded by seeking permission and community mobilisation.
  • At the time, only 6% to 9% of the adults who took part in the programme were already immunised.
  • The leaders were asked for their cooperation in encouraging eligible community members to take the COVID-19 vaccine.
  • Finally, vaccine doses and healthcare workers arrived at the villages to administer the doses.

Looking forward

  • This approach proved 76% more cost-effective than other vaccination campaigns.
  • Transport accounted for a large share of the costs, so the cost-effectiveness of last mile delivery can be increased by offering a “bundle” of health products.
  • Other estimates put the death toll for the same period at 14.83 million, which is 2.74 times higher.
  • Developing cost-effective strategies to make vaccines easily accessible to everyone, everywhere, is the most promising solution to prevent future pandemics.

Drinking apple cider vinegar may help with weight loss but its health benefits are overstated

Retrieved on: 
Wednesday, April 10, 2024

One day, she explained that she adds apple cider vinegar to improve my health.

Key Points: 
  • One day, she explained that she adds apple cider vinegar to improve my health.
  • Apple cider vinegar is a natural product made of fermented apple juice that has gone sour.
  • I decided to turn medical sleuth and investigate whether apple cider vinegar is as good for health as it sounds.

Claim: disinfectant properties

  • But does apple cider vinegar’s decontaminant qualities translate to the human gut?
  • Our stomachs produce acid, which acts as a natural barrier to infection, so how can adding more acid help?

Claim: weight loss and management of type 2 diabetes

  • There are plenty of anecdotal claims that apple cider vinegar can aid weight loss, supported by limited evidence from several small studies.
  • Apple cider vinegar is thought to cause weight loss through its effect on delay of gastric emptying.
  • Reduced calorific intake will lead to weight loss – but how are the metabolic effects on blood glucose and lipids mediated?
  • In type 2 diabetes there is a reduction in sensitivity to insulin which in turn leads to a reduced uptake of glucose by cells.

Claim: reduces risk of heart disease

  • Raised blood lipids are a risk factor for cardiovascular diseases such as myocardial infarction and stroke.
  • Well, I’m afraid there’s no scientific evidence that vinegar consumption of any kind reduces cardiovascular morbidity and mortality in those with or without diabetes.

Claim: cancer treatment and prevention

  • One of the more outrageous claims of benefits of daily apple cider vinegar consumption is that it may prevent or treat cancer.
  • A frequently quoted case-control study from China found that an increased consumption of vinegar was associated with a reduced incidence of oesophageal cancer.

PFAS ‘forever chemicals’: Why EPA set federal drinking water limits for these health-harming contaminants

Retrieved on: 
Wednesday, April 10, 2024

The U.S. Environmental Protection Agency now believes there is no safe level for two common PFAS – PFOA and PFOS – in drinking water, and it acknowledges that very low concentrations of other PFAS present human health risks.

Key Points: 
  • The U.S. Environmental Protection Agency now believes there is no safe level for two common PFAS – PFOA and PFOS – in drinking water, and it acknowledges that very low concentrations of other PFAS present human health risks.
  • The agency issued the first legally enforceable national drinking water standards for five common types of PFAS chemicals, as well as PFAS mixtures, on April 10, 2024.

What exactly are PFAS?

  • This is a large group of human-made chemicals – currently estimated to be nearly 15,000 individual chemical compounds – that are used widely in consumer products and industry.
  • They can make products resistant to water, grease and stains and protect against fire.
  • The short answer is that PFAS are harmful to human health and the environment.
  • Some of the very same chemical properties that make PFAS attractive in products also mean these chemicals will persist in the environment for generations.
  • The U.S. Geological Survey estimates common types of PFAS are now in at least 45% of the country’s tap water.

What are the health risks from PFAS exposure?

  • Research consistently demonstrates that PFAS are associated with a variety of adverse health effects.
  • A review by a panel of experts looking at research on PFAS toxicity concluded with a high degree of certainty that PFAS contribute to thyroid disease, elevated cholesterol, liver damage, and kidney and testicular cancer.
  • Additionally, current research suggests that babies exposed prenatally are at higher risk of experiencing obesity, early-onset puberty and reduced fertility later in life.
  • Collectively, this is a formidable list of diseases and disorders.

Who’s regulating PFAS?

  • DuPont called it Teflon, which eventually became a household name for its use on nonstick pans.
  • Decades later, in 1998, Scotchgard maker 3M notified the Environmental Protection Agency that a PFAS chemical was showing up in human blood samples.
  • At the time, 3M said low levels of the manufactured chemical had been detected in people’s blood as early as the 1970s.
  • The Agency for Toxic Substances and Disease Registry has a toxicological profile for PFAS.

How can you reduce your PFAS exposure?

  • The best ways to protect yourself and your family from risks associated with PFAS are to educate yourself about potential sources of exposure.
  • Products labeled as water- or stain-resistant have a good chance of containing PFAS.
  • Strategies for monitoring and reporting PFAS contamination vary by location and PFAS source, so the absence of readily available information does not necessarily mean the region is free of PFAS problems.
