Footsteps required for reliable and valid in-shoe plantar pressure assessment during gait per foot region in people with hallux valgus.

Background: Plantar pressure assessment is commonly performed to identify pathognomonic gait characteristics and evaluate therapeutics against them in people with various foot disorders. Little is known about the reliability and validity of this assessment in people with hallux valgus (HV) per foot region.

Research Question: This study aimed to assess the reliability and validity of the in-shoe plantar pressure measurement method during gait in people with HV and the required number of footsteps, as an intra-subject sample size, to ensure a reliable and valid use of this method.

GLP-1 secretion in response to oral and luminal palatinose (isomaltulose) in rats.

Palatinose (isomaltulose), a slowly digested disaccharide, is used as a non-cariogenic sugar and as a sucrose substitute in several foods. Because of its ability to lower postprandial glycemia, palatinose may be beneficial as a treatment for impaired glucose metabolism. Glucagon-like peptide-1 (GLP-1) improves glycemia via enhancing pancreatic beta-cell functions.

Studies on absorption and metabolism of palatinose (isomaltulose) in rats.

We evaluated the absorption and metabolism of palatinose in rats by the carbohydrate load test and the 13C- and H2-breath tests. We compared the results of these tests with those of sucrose, since sucrose is an isomer of palatinose and generally known to be degraded and absorbed from the small intestine. In the carbohydrate load test, blood glucose and plasma insulin levels after oral administration of palatinose rose more gradually and reached a maximum that was lower than that after sucrose administration.

Palatinose-blended sugar compared with sucrose: different effects on insulin sensitivity after 12 weeks supplementation in sedentary adults.

Background: We investigated the effects of daily palatinose intake on the risk factors of metabolic syndrome in sedentary non-obese Japanese adults.

Methods: Japanese adults (40 females and 10 males, age: 53 +/- 9 years, range: 31-72 years old) were randomized into two groups for a double-blind, placebo-controlled intervention study and given either 40 g/day palatinose-blended sugar (PS group) or 40 g/day sucrose (S group) in their diet for 12 weeks.

Results: After the intervention, the insulin resistance index (HOMA-IR) had significantly decreased only in the PS group; the inter-group difference was significant at P = 0.
