Tuberculosis

PhD student Dr Ishita Marwah writes about her personal take on tuberculosis – a disease that continues to be a global issue.

Eliminating gluten from his diet transformed his career. (more…)

Smoking is a leading cause of preventable death and disease in the world. It is estimated that the society costs associated with smoking are approximately ₤12.9 billion a year, including the NHS cost of treating smoking related diseases and loss of productivity.

Chronic obstructive pulmonary disease (COPD) is one of the major diseases caused by smoking. The disease ranks third among the leading causes of death worldwide. Around 1.2 million Britons suffer from the disease (Source: British Lung Foundation). The usual clinical picture is that of a smoker with symptoms that include shortness of breath and chronic cough.
