Dietary assessment, while traditionally based on pen-and-paper, is rapidly moving towards automatic approaches. This study describes an Australian automatic food record method and its prototype for dietary assessment via the use of a mobile phone and techniques of image processing and pattern recognition. Common visual features including scale invariant feature transformation (SIFT), local binary patterns (LBP), and colour are used for describing food images. The popular bag-of-words (BoW) model is employed for recognizing the images taken by a mobile phone for dietary assessment. Technical details are provided together with discussions on the issues and future work.

This two-phase study aims to develop the Turkish version of the German Eating Behavior Scale (SEV-Tr), and to investigate the potential associations of eating behaviors with nutritional and health status. In the first phase, the original scale was adapted to the Turkish language and its validity and reliability were assessed in 299 healthy individuals aged 19-64 years. In the second phase, the SEV-Tr was retested in a study population of 110 healthy individuals, aged 19-64 years, and the potential associations between the SEV-Tr score, anthropometrical and biochemical measurements, and other eating behaviors assessed by the Three-Factor Eating Questionnaire (TFEQ-Tr21) were examined.

Full-arch implant rehabilitation in extremely atrophic edentulous mandibles is still challenging due to the high risk of fracture and the limited bone availability. The approach proposes using short implants with immediate loading for final prostheses as a treatment option, which offers shorter treatment times and fewer invasive procedures. A 66-year-old female patient with an edentulous mandible and severe alveolar bone resorption was treated with four short implants in the interforaminal area.
