Association between real-world home blood pressure measurement patterns and blood pressure variability among older individuals with hypertension: A community-based blood pressure variability study.

Home blood pressure (BP) monitoring is a useful tool for hypertension management. BP variability (BPV) has been associated with an increased risk of cardiovascular events. However, little is known about the correlation between BPV and different measurement patterns of long-term home BP monitoring. This longitudinal cohort study aimed to assess the associations between dynamic BP measurement patterns and BPV. A total of 1128 participants (mean age, 77.4 ± 9.3 years; male, 51%) with 23 269 behavior measuring units were included. We used sliding window sampling to classify the home BP data with a regular 6-month interval into units in a sliding manner until the data are not continuous. Three measurement patterns (stable frequent [SF], stable infrequent [SI], and unstable [US]) were assessed based on the home BP data obtained within the first 3 months of the study, and the data in the subsequent 3 months were used to assess the BPV of that unit. We used linear mixed-effects model to assess the association between BP measurement patterns and BPV with adjustment for possible confounding factors including average BP. Average real variability and coefficient variability were used as measures of the BPV. No significant differences were observed in average BP between the SF, SI, and US patterns. However, BPV in the SF group was significantly lower than that in the US and SI groups (all p-values < .05). The BPV in SI and US groups was not significantly different. A stable and frequent BP measuring pattern was independently associated with a lower BPV.

Galectin-12 is Involved in Corn Silk-Induced Anti-Adipogenesis and Anti-Obesity Effects.

Obesity is a significant risk factor for various diseases. It is a clinical condition caused by the excessive accumulation of fat, which has a negative impact on human health. Galactin-12 is an adipocyte-expressed protein and possesses adipocyte-inducing activity. We investigated the expression level of candidate proteins involved in galactin-12-mediated adipocyte differentiation pathway. We performed a high-throughput screening assay to monitor galectin-12 promoter activity using 105 traditional Chinese herbs. Corn silk extract and [Formula: see text]-sitosterol reduced the expression of galactin-12 promoter in 3T3-L1 cells. In addition, corn silk extract and [Formula: see text]-sitosterol decreased the level of lipid droplets and downregulated the gene and protein expression level of C/EBP[Formula: see text], C/EBP[Formula: see text], PPAR[Formula: see text], Ap2, and adipsin in 3T3-L1 pre-adipocytes via AKT and ERK1/2 inhibition. In vivo study with the oral administration of corn silk extract and [Formula: see text]-sitosterol in a mouse model showed a significant weight reduction and decrease in adipocytes in several organs such as the liver and adipose tissue. Taken together, corn silk extract and [Formula: see text]-sitosterol may effectively reduce pre-adipocyte differentiation by inhibiting galectin-12 activity and exerting anti-obesity effects. These findings highlight the potential use of corn silk extract and [Formula: see text]-sitosterol as potential candidates for the prevention and treatment of obesity.
