Chemosensory impairment and appetite: commentary on "Impaired sensory functioning in elders: the relation with its potential determinants and nutritional intake"

Article Abstract:

The observation by de Jong et al. on the relationship between impaired taste and smell function and poor appetite is very significant. Poor appetite is a major reason for the reduced energy intake that occurs with advancing age. The findings are in agreement with the observation that intensification of flavor and taste can enhance food palatability and/or intake, increase salivary flow and immunity, and decrease oral complaints in both sick and healthy elders. However, additional studies must be conducted to find out the effect of chemosensory losses on dietary quality and other nutritional factors.

Commentary on 'The Effects of Peripheral Vascular Disease on Gait.'

Article Abstract:

'The Effects of Peripheral Vascular Disease on Gait,' a study conducted by McCully, Kevin, et. al., presents one of the most detailed examinations of gait in individuals with peripheral arterial disease. The findings reveal that, in patients pushed to the limit of claudication, a proportional overall slowing of gait instead of limping occurs. The slowing of an individual's gait, a good predictor of poor health in older persons, is the result of reduced cadence and step length combined with increased step time and support time.
