Most women have periods for nearly 40 years. Over this time, women should be able to make choices to enable their own positive reproductive health and wellbeing, such as if and when to have children or how to access healthcare and treatment. Unfortunately, many areas of reproductive health, including abortion, miscarriages, infertility and menstrual issues, continue to be taboo topics and many women feel unheard, even when they have sought professional help.

The first time I visited an environmental surveillance (ES) site was back in 2015. It was hot, the sampled river was black and meandering between backyards of houses (see the photo above). The river had pipes where sewage was deposited, and the area was used to dispose of refuse. Further downstream women were washing clothes and kids were splashing around. But just a month before a river sample yielded poliovirus, related to cases elsewhere in the country. I was in Rawalpindi, Pakistan. At that time, and even now, ES is supplementing clinical surveillance to support polio eradication.

What is going on with the weather in the Northern Hemisphere at the moment? The main reason is a wind pattern in the upper atmosphere – known as the jet stream - which is blocked or rather stationary. This is causing very hot, dry conditions over southern Europe, as well as southern US, north Africa and parts of Asia. In the UK it’s bringing cooler, wetter weather. At the same time, El Nino – a weather phenomenon which brings warmer sea surface temperatures in the equatorial Pacific roughly every 3-7 years – arrived in 2023.
As clinical researchers, we are motivated by knowing that the type of work and research we do can ultimately make a positive impact on our global health. We hope to contribute to scientific knowledge that will inform policy decisions on the introduction and use of vaccines. We also hope to improve their accessibility and affordability. This is crucial for reducing the burden of vaccine-preventable diseases like pneumonia in low- and middle-income countries, and ensuring that vulnerable populations are not left behind.
To meet the UK’s greenhouse gas (GHG) emissions targets, the Climate Change Committee (CCC) recommended to reduce current meat and dairy intake by 20% by 2030. Compared to plant-based, animal products have significant higher carbon emissions and land and water footprints. A shift towards plant-based diets, rich in fruit and vegetables, nuts and wholegrains would also reduce the risk of mortality and chronic disease morbidity, including cardiovascular disease, cancer and type 2 diabetes.

Today, World Environment Day 2023 is all about tackling plastic pollution. This is timely not least as countries around the world emerge from a week of international negotiations as part of the development of a global, legally binding, treaty to end plastic pollution. Plastic is now so pervasive in our environment as to constitute a new era: the Plasticene.

The management of the cancer backlog following the COVID-19 pandemic is one of the UK’s major political and clinical issues. Figures for September 2022 show for example that only 61.7% of patients are receiving treatment within 62 days of a referral, compared to 82.3% in the period between April 2017 and March 2018. Short-term public health solutions are urgently required to address current delays in treatment.

Children with disabilities, especially in low-and middle-income countries, face challenges in getting a good education and having opportunities to grow. Even though the United Nations has set goals for inclusive education for all, progress has been slow and planning often doesn't take into account the unique needs of children with disabilities and their families.
In 2022, global population reached eight billion people. This milestone represents a hugely positive story of human achievement in reducing mortality rates worldwide. A couple of centuries ago, life expectancy at birth for the average global citizen would have been in the 30s or below; so low because high proportions of children died in their first few years of life. Child mortality has since plummeted, meaning far fewer families have to grieve children lost in childhood, and far more children grow up to achieve their full adult potential.

Globally, tuberculosis (TB) still causes 1.6 million deaths a year, with another 10 million people developing the disease. We know that half of those with infectious TB do not report symptoms, and that the disease exists on a spectrum that can progress and regress over time if left untreated.
