Background: Salmonella is a food- and water-borne pathogen that can be easily spread in a population, leading to the outbreak of salmonellosis that is caused by ingestion of mixed salads contaminated by the pathogen. Most cases occur in the late spring months and can be seen as single cases, clusters, or episodes.

Objective: The aim of this study was to describe the incidence and epidemiological characteristics of salmonellosis in the State of Qatar.

Methods: This was a retrospective, descriptive study carried out in laboratory-confirmed cases of salmonellosis during 2004-2012 from all Salmonella surveillance centers. Therapeutic records of patients who were clinically suspected of having Salmonella diseases were analyzed. Initially, cases with typhoid fever were investigated in the laboratory by means of Widal agglutination tests, while non-typhoidal Salmonella diseases were determined based on culture technique.

Results: The annual incident of salmonellosis cases were 12.3, 23.0, 30.3, 19.4, 15.3, 18.0, 22.7, 18.5, and 18.1 per 100,000 population in 2006-2011 and 2012, respectively. The number of salmonellosis cases was high among less than 2-year-old females and 3-year-old males. In addition, one-fourth of patients (27.7%) were Qatari when compared to other nationalities. A significant difference in age was found between Qatari (6.08 ± 12.28 years) and non-Qatari (15.04 ± 19.56 years) patients. Of the reported cases, 79.8% included the onset date of the first symptoms. Contact phone numbers were available for 94% of the cases but addresses were available for only 50.4% of cases. The time difference between onset of symptoms and diagnosis was 5.4 ± 5.7 days. The most frequent serotype reported were type b (41.9%), type d (26.9%), and type c1 (12.2%).

Conclusion: The present surveillance data showed a high incidence of salmonellosis in Qatar that poses a serious public health problem. Special intervention and health awareness programs are required for early screening, detection, and treatment as well as for strengthening the surveillance system of salmonellosis, with special emphasis on the laboratory study of cases.

How Google's 'ten Things We Know To Be True' could guide the development of mental health mobile apps.

Health Aff (Millwood) 2014 Sep;33(9):1603-11

Ara Darzi is executive chair of WISH, Qatar Foundation, and director of the Institute of Global Health Innovation, Imperial College London.

From 2011 to 2030, mental health conditions are projected to cost the global economy $16 trillion through lost labor and capital output. The gold standard of psychological interventions, one-on-one therapy, is too costly and too labor-intensive to keep up with the projected growth in demand for mental health services. Therefore, new solutions are needed to improve the efficiency of mental health care delivery and to increase patient self-care. Because 85 percent of the world's population has wireless signal coverage, there is an unprecedented opportunity for mobile technologies to incorporate psychological self-care into people's daily lives and relieve workforce shortages. In this article, we suggest that policy makers look to technology innovators for guidance. For example, Google's principles, called "Ten Things We Know To Be True," are useful for understanding the drivers of success in mobile technologies. For principles such as "focus on the user and all else will follow," we identify examples of how evidence-based mobile mental health technologies could increase patient self-care and reduce the demand for one-on-one psychological intervention.
