Teaching Global Health at the Frontlines: A multidisciplinary course in Peru presents basic concepts to students

The authors discuss a unique project to teach medical students in Peru about global health, which included a trip to the mining town of La Oroya at 15,610 feet above sea level in the Peruvian Andes

Telephone clinic improves gluten-free dietary adherence in adults with coeliac disease: sustained at 6 months

Background: A gluten-free (GF) diet is the only treatment for coeliac disease (CD), non-adherence to the diet is associated with greater morbidity. The study aimed to examine the effect of a telephone clinic, designed to increase GF dietary knowledge and adherence, in adults with CD. Methods: A prospective study of 125 patients with histologically confirmed CD. Patients, not adhering to a GF diet (n=30), engaged in a personalised telephone clinic. Validated questionnaires were used to assess GF dietary adherence (Coeliac Disease Adherence Test; CDAT), knowledge of GF foods and CD-related quality of life (QoL). GF dietary adherence was assessed up to 12 months post telephone clinic. The control group completed the questionnaires only. Results: GF dietary adherence (CDAT) median scores significantly improved at 3 and 6 months after the telephone clinic compared with baseline (16, 13 and 13, respectively, p<0.01). Reassuringly, the dietary burden QoL score remained similar to baseline values. No change in CDAT scores were observed in the control group. Change in GF dietary knowledge score was associated with improved GF dietary adherence CDAT score (r=−0.22; p=0.039). At 9 and 12 months, CDAT scores were similar to baseline values. Conclusions: Telephone clinics have a positive impact on dietary knowledge and GF dietary adherence in adults with CD, promoting health-benefitting behaviours in those previously not adhering to a GF diet. The study highlights the need for patients to have regular follow-up, with targeted reviews for those not adhering to a GF diet

Lauric acid is an inhibitor of Clostridium difficile growth in vitro and reduces inflammation in a mouse infection model

Indexación: Scopus.Clostridium difficile is a Gram-positive, spore-forming anaerobic human gastrointestinal pathogen. C. difficile infection (CDI) is a major health concern worldwide, with symptoms ranging from diarrhea to pseudomembranous colitis, toxic megacolon, sepsis, and death. CDI onset and progression are mostly caused by intestinal dysbiosis and exposure to C. difficile spores. Current treatment strategies include antibiotics; however, antibiotic use is often associated with high recurrence rates and an increased risk of antibiotic resistance. Medium-chain fatty acids (MCFAs) have been revealed to inhibit the growth of multiple human bacterial pathogens. Components of coconut oil, which include lauric acid, have been revealed to inhibit C. difficile growth in vitro. In this study, we demonstrated that lauric acid exhibits potent antimicrobial activities against multiple toxigenic C. difficile isolates in vitro. The inhibitory effect of lauric acid is partly due to reactive oxygen species (ROS) generation and cell membrane damage. The administration of lauric acid considerably reduced biofilm formation and preformed biofilms in a dose-dependent manner. Importantly, in a mouse infection model, lauric acid pretreatment reduced CDI symptoms and proinflammatory cytokine production. Our combined results suggest that the naturally occurring MCFA lauric acid is a novel C. difficile inhibitor and is useful in the development of an alternative or adjunctive treatment for CDI.https://www.frontiersin.org/articles/10.3389/fmicb.2017.02635/ful

Food knowledge and psychological state predict adherence to a gluten-free diet in a survey of 5310 Australians and New Zealanders with coeliac disease

© 2018 John Wiley & Sons Ltd. Background: A gluten-free diet treats coeliac disease, but its efficacy depends on strict adherence. A variety of patient factors may influence adherence but have not been well described at a population level. Aim: To comprehensively assess the patient factors that influence gluten-free diet adherence in patients with coeliac disease. Methods: Patients with coeliac disease completed an online survey comprising the validated Celiac Dietary Adherence Test in addition to data on demographics, details of diagnosis and management and assessment of diet knowledge, quality of life and psychological distress. Survey data were analysed for predictors of adherence and quality of life. Results: Of 7393 responses, 5310 completed the Celiac Dietary Adherence Test and 3230 (61%) were adherent to a gluten-free diet. Multivariate regression showed older age, being male, symptoms after gluten ingestion, better food knowledge and lower risk of psychological distress were independent predictors of adherence (each P = 0.008). Additionally, dietary adherence was associated with better quality of life (P &lt; 0.001; multiple regression). Respondents who considered themselves to have poor food knowledge were more likely to incorrectly identify gluten-free foods, but could still recognise gluten-containing foods, suggesting that poor knowledge may lead to over-restriction of diet. Conclusions: Poor knowledge of a gluten-free diet and psychological wellbeing were independent modifiable risk factors for inadequate adherence to a gluten-free diet in patients with coeliac disease. Involvement of both a dietitian and mental health care professional, in the presence of psychological distress, is likely to be necessary to improve adherence and health outcomes

Review article : coeliac disease in later life must not be missed

Background: The presenting symptoms of coeliac disease are often subtle and the diagnosis is frequently delayed or overlooked. Therefore, especially elderly patients may be denied the benefits conferred by gluten free diet which can be dramatically life-changing. Aim: To review the occurrence, clinical features, diagnosis and management in coeliac patients detected later in life. Methods: To review manuscripts concerned with coeliac disease in the elderly and to derive subgroups of elderly people from publications on the disorder. Results: Approximately a quarter of all diagnoses are now made at the age of 60 years or more and a fifth at 65 years or over. About 4% are diagnosed at 80 years or above. Around 60% remain undetected, since their symptoms are often subtle: tiredness, indigestion, reduced appetite. Good compliance with gluten free diet, resolution of symptoms and improvement in laboratory indices can be achieved in over 90% of patients. Conclusions: Coeliac disease not uncommonly presents for the first time in older patients and is an important diagnosis to make.Peer reviewe
