Proximal femur fat fraction variation in healthy subjects using chemical shift-encoding based MRI.

The objective of this study was to describe the normal variation of bone marrow fat content in the proximal femur considering the influence of side, age, sex and body mass index using fat fraction MRI. From September 2012 to July 2016, the MRI of 131 patients (258 hips) considered to have a normal MRI appearance were retrospectively evaluated. Patient records were searched to allow calculation of the body mass index (BMI).

EarBit: Using Wearable Sensors to Detect Eating Episodes in Unconstrained Environments.

Chronic and widespread diseases such as obesity, diabetes, and hypercholesterolemia require patients to monitor their food intake, and food journaling is currently the most common method for doing so. However, food journaling is subject to self-bias and recall errors, and is poorly adhered to by patients. In this paper, we propose an alternative by introducing EarBit, a wearable system that detects eating moments.

Exploring Symmetric and Asymmetric Bimanual Eating Detection with Inertial Sensors on the Wrist.

Motivated by health applications, eating detection with off-the-shelf devices has been an active area of research. A common approach has been to recognize and model individual intake gestures with wrist-mounted inertial sensors. Despite promising results, this approach is limiting as it requires the sensing device to be worn on the hand performing the intake gesture, which cannot be guaranteed in practice.

Outcomes among HIV-infected children initiating HIV care and antiretroviral treatment in Ethiopia.

Objective: To describe pediatric ART scale-up in Ethiopia, one of the 21 global priority countries for elimination of pediatric HIV infection.

Methods: A descriptive analysis of routinely collected HIV care and treatment data on HIV-infected children (<15 years) enrolled at 70 health facilities in four regions in Ethiopia, January 2006-September 2013. Characteristics at enrollment and ART initiation are described along with outcomes at 1 year after enrollment.
