Setting: The three Basic Management Units (BMUs) of the National Tuberculosis Programme (NTP) in Cotonou, Benin.

Objective: To determine the prevalence of diabetes mellitus (DM) among tuberculosis (TB) patients in Cotonou.

Design: A cross-sectional study of consecutively registered TB patients treated for a minimum of 2 weeks between June and July 2014 in the three BMUs, with measurement of their fasting blood glucose (FBG). A patient was considered as having DM if venous FBG was ⩾7 mmol/l or if they reported a known history of DM.

Result: There were 159 patients assessed: 114 with new smear-positive pulmonary tuberculosis (PTB), 5 with new smear-negative PTB, 8 with extra-pulmonary TB, 21 retreatment patients with fully susceptible bacilli and 11 with multidrug-resistant TB. Of these, respectively 31 (19%), 18 (11%) and 10 (6%) were human immunodeficiency virus co-infected, smokers and hypertensive. Eight patients (5%) had impaired fasting glucose and three (1.9%) had DM (FBG ⩾ 7 mmol/l), of whom two were already known to have the disease and one was newly diagnosed.

Conclusion: DM may not be an important risk factor for TB in Cotonou. A larger study on TB and DM in the whole country is needed.

Background: Our authors from around the world met to summarise the available knowledge, decide which potentially modifiable risk factors for dementia have compelling evidence and create the most comprehensive analysis to date for potentially modifiable risk factors to inform policy, give individuals the opportunity to control their risks and generate research.

Method: We incorporated all risk factors for which we judged there was strong enough evidence. We used the largest recent worldwide meta-analyses for risk factor prevalence and relative risk and if not available the best data.

Background: India is unfortunately the "Diabetes Capital" of the world with estimated 101 million and 136 million patients suffering from diabetes and prediabetes respectively. Prediabetes is a transition state between euglycemia and diabetes. Although diabetes is associated with cognitive decline, studies that link prediabetes and cognition have been scarce and inconclusive especially from the Low and Middle Income (LMIC) countries.
