@hfalcke, this call for an interdisciplinary study!

The BMJ · The survival time of chocolates on hospital wards: covert observational studyObjective To quantify the consumption of chocolates in a hospital ward environment. Design Multicentre, prospective, covert observational study. Setting Four wards at three hospitals (where the authors worked) within the United Kingdom. Participants Boxes of Quality Street (Nestlé) and Roses (Cadbury) on the ward and anyone eating these chocolates. Intervention Observers covertly placed two 350 g boxes of Quality Street and Roses chocolates on each ward (eight boxes were used in the study containing a total of 258 individual chocolates). These boxes were kept under continuous covert surveillance, with the time recorded when each chocolate was eaten. Main outcome measure Median survival time of a chocolate. Results 191 out of 258 (74%) chocolates were observed being eaten. The mean total observation period was 254 minutes (95% confidence interval 179 to 329). The median survival time of a chocolate was 51 minutes (39 to 63). The model of chocolate consumption was non-linear, with an initial rapid rate of consumption that slowed with time. An exponential decay model best fitted these findings (model R2=0.844, P<0.001), with a survival half life (time taken for 50% of the chocolates to be eaten) of 99 minutes. The mean time taken to open a box of chocolates from first appearance on the ward was 12 minutes (95% confidence interval 0 to 24). Quality Street chocolates survived longer than Roses chocolates (hazard ratio for survival of Roses v Quality Street 0.70, 95% confidence interval 0.53 to 0.93, P=0.014). The highest percentages of chocolates were consumed by healthcare assistants (28%) and nurses (28%), followed by doctors (15%). Conclusions From our observational study, chocolate survival in a hospital ward was relatively short, and was modelled well by an exponential decay model. Roses chocolates were preferentially consumed to Quality Street chocolates in a ward setting. Chocolates were consumed primarily by healthcare assistants and nurses, followed by doctors. Further practical studies are needed.

"Model simulations demonstrate that initiating self-isolation shortly after smartwatch-based disease detection could lower the reproduction number of these diseases to below 1, across diverse epidemiological conditions, various smartwatch detection accuracies, and realistic self-isolation rates... findings suggest a potential revolution in... control of seasonal diseases and future pandemics through the utilization of smartwatch-based detection systems."

Hi, I am Stéphane!

I'm a researcher in epidemiology and a medical doctor. My research areas include #AirPollution health effect, epidemiology and hopefully more on climate change in the coming years.

Occasionally talking about #FOSS, #RStats, #BigData, #PublicHealth and #teaching

Working at the University of Copenhagen.

Roald Dahl’s Heartbreaking Letter About Losing his Daughter to measles in 1962 - Roald Dahl, the beloved author of my personal favorites Charlie and the Chocolate Factory, Matilda and The BFG, lost his eldest daughter, Olivia, to #measles in the early 60s. It wasn’t until 1988, however, that he penned a remarkable letter that doubles as a plea to parents, urging them to have their children vaccinated… #Vaccines #Vaccination #PublicHealth #InfectiousDisease #epidemiology

Valuable read from Dr. Troy Tassier from dual viewpoints of #economics and #epidemiology.

"President Bush felt strongly about the program and it paid off. Big time. Likely no other piece of legislation enacted by a United States President has saved as many lives as PEPFAR."
