'Diabulima' through the lens of social media: a qualitative review and analysis of online blogs by people with Type 1 diabetes mellitus and eating disorders.

AIMS: To perform a qualitative review of online blogs authored by people self-identifying as having Type 1 diabetes and an eating disorder or 'diabulimia', a term used by people with Type 1 diabetes to describe an eating disorder that is characterized by deliberate restriction of insulin to control weight. METHODS: We conducted a structured qualitative review of online blogs published between 2012 and 2017 authored by people who report having Type 1 diabetes and an eating disorder or diabulimia. The subsequent thematic analysis followed a six-phase process and was conducted by two independent researchers. RESULTS: From 147 000 search results, 11 blogs (304 posts) matched criteria for further analyses. Three key themes and 18 subthemes emerged: 1) different aspects of bloggers' relationship with insulin, including motives for omitting insulin, secrecy of insulin omission and perception of control; 2) bloggers' experiences of diabetes complications, and diabetes ketoacidosis in particular, as well as their worries about future complications; 3) strategies for recovery and triggers for relapse, which involved diabetes self-management and setting up a support system. CONCLUSIONS: Qualitative analyses of blogs authored by people with Type 1 diabetes and an eating disorder or diabulimia have identified high levels of diabetes distress and provided insight into different motives for insulin omission and strategies for recovery. Considering the limited evidence for effective interventions, these findings may help the development of complex interventions to improve biomedical and psychological outcomes in this group.

Molecular testing (strand displacement assay) for identification of urethral gonorrhoea in men: can it replace culture as the gold standard?

The objective was to evaluate the performance of Becton Dickinson's BD Probe Tec(TM) (BDPT) strand displacement amplification (SDA) test for the detection of Neisseria gonorrhoeae on urethral specimens from men with urethritis compared with conventional culture and to show that SDA improves the diagnostic yield of gonorrhoea infections (GC). Anonymized retrospective testing of stored urethral swab samples from men attending genitourinary services in East London was performed using SDA. The prevalence of GC culture positive infections in this sample was 20/152 (13%). The sensitivity, specificity, positive predictive value and negative predictive value for the BDPT-SDA system compared with culture were 100%, 95%, 77% and 100%, respectively. In this study population, the BDPT-SDA assay was a highly sensitive and specific test for the diagnosis of N. gonorrhoeae from urethral swabs in men. Therefore, SDA can be used to complement culture in the diagnosis of N. gonorrhoeae infection. No ethics committee approval was obtained as all samples were anonymized.
