Instead cheap propecia 1mg mastercard hair loss uae, you could look for research reports that explore the person’s experience 5 mg propecia fast delivery hair loss cure by quran, or a review of such research. This is likely to be through asking them about it using a qualitative approach and probably in-depth interviews. If your friend in the example above wants to know about how other people have experi- enced a particular anti-malarial tablet and the side-effects, you need to look for research that explores patients’ experiences of taking malaria tablets. In this situation, this could be diffcult to fnd out exactly how many people adhere to a prophylaxis regime, without undercover observers, which would clearly be impossible! Instead, those concerned with the adher- ence with the prophylaxis against malaria would need to rely on the patient’s own reported adherence to the anti-malarial drugs prescribed. Example: Imagine that you are concerned about infection in your unit and want to fnd out about how compliant staff are with hand-washing/hand-rubbing poli- cies. Imagine that you then found a questionnaire study that had asked staff at the end of every shift whether they always follow infection control procedures. Consider the answers they are likely to give and whether these would refect what they actually do. What type of evidence would you be looking for that would really tell you about staff adherence to infection control policy? Clearly the answer is to fnd observational studies, in which an observer has sat and watched to see if staff washed their hands or not in the everyday context. Thus for this question, the very best type of evidence would be observational studies. Our recall or description of what we do can be different from what we actually do! You can see from these examples that it is helpful to be able to ‘pin point’ the type of research you are looking for and that different types of research inform us about different aspects of professional practice and decisions that need to be made.

Gut microorganisms account for 10 times as many cells in the human body, coding for 150 times more genes than our genome (Gill et al. They may play pivotal roles in the pathogenesis of all the major diseases of our time, including cancer, heart disease, autoimmune dis- ease, and metabolic diseases. Furthermore, their regulation and manipulation may be the foundation for powerful therapies in the future. Given their diverse roles, perhaps it is not surprising that gut microorganisms seem to also play a critical role in the human nutrition–infection interaction, as best demonstrated by studies in malnourished children. Malnourished children worldwide are caught in a vicious cycle between infection and poor nutrition. They experience various gastrointestinal infections, which dam- age intestinal tissue and hamper absorption of nutrients. Without nutrients, they lack the building blocks to repair mucosa and mount an effective immune response. As a result, they remain vulnerable to more infections, which lead to further malnutri- tion, which perpetuates tragic loops that continue through the most critical years of 247 248 Nutrition–Infection Interactions and Impacts on Human Health physical and mental growth. The cycle’s consequences are far-reaching, resulting in stunted and cognitively impaired children, thereby permanently crippling the most productive future members of many societies. This chapter discusses the gut microbiome’s role in malnourished children and the infection-poor nutrition cycle. We frst discuss recent studies establishing that healthy and malnourished children have distinctly different gut microbiomes.
