Salmon nasal cartilage proteoglycan stimulates hair growth.

Hair loss is a commonly encountered problem. In this study, hair growth was enhanced by daily oral ingestion of salmon nasal cartilage proteoglycan (PG) in mice. Proteoglycan stimulated vesicular endothelial growth factor production in human follicle dermal papilla cells through insulin growth factor-1 receptor signaling, suggesting the possibility of hair loss improvement by PG ingestion.

Effect of Early Rehabilitation on Walking Independence and Health-Related Quality of Life in Patients With Chronic Foot Wounds: A Multicenter Randomized Clinical Trial.

Rehabilitation is usually provided to patients with chronic foot wounds (CFWs) after surgery. This study aimed to assess whether early postoperative rehabilitation could maintain walking independence in hospitalized patients with CFWs. This single-blind, randomized clinical trial was performed between September 10, 2018 and March 2019, involving 60 patients who underwent both surgical procedures and rehabilitation. Participants were randomly allocated into the early rehabilitation (EG, n = 30) or the control (CG, n = 30) groups. EG received early rehabilitation immediately after surgery, while CG received late rehabilitation after wound closure. Both groups received rehabilitation sessions 5 times per week until discharge. The primary outcome was walking independence, measured via Functional Independence Measure (FIM)-gait scores. Secondary outcomes included health-related quality of life (HRQoL) using EuroQol 5 dimensions 5-level (EQ-5D-5L) and the presence of rehabilitation-related adverse events, including dehiscence of wounds and falls. Differences in intervention timing effects were analyzed using nonparametric split-plot factorial design analysis, including Fisher's exact test, Mann-Whitney U test, and Wilcoxon signed-rank test (P < .05). Out of the 60 participants, 53 patients completed the discharge follow up. Three participants (10.0%) from the EG and 4 (13.3%) from the CG dropped out due to postoperative complications unrelated to rehabilitation intervention. No rehabilitation-related adverse events were found. Participants in the EG maintained greater FIM-gait scores during hospitalization than the CG (difference, -1; P = .0001), with a difference of 0 (P = .109) at discharge. EQ-5D-5L significantly improved in both groups (EG: difference, 0.13 [P = .014], CG: difference, 0.17 [P = .0074]). The EG intervention was associated more with maintaining walking independence at discharge than CG intervention. Postoperative rehabilitation improved HRQoL without adverse events, indicating that clinicians should recommend early rehabilitation for patients with CFW to enhance walking independence.

Validation of the Risk Score of the Mortality and Lower Limb Loss Considering Ambulatory Status after Surgical Revascularization in Maintaining Patients with Dialysis.

Surgical revascularization is performed to preserve limb and to maintain functional status of patients with critical limb ischemia (CLI). The PREVENT III risk score helps to predict the postoperative course of CLI. However, this score is not available to estimate the risk of amputation or death properly in patients with hemodialysis (HD) and tissue loss (HD: 4 points, Tissue loss: 3 points), because they are classified as a high-risk group. Therefore, we investigated 213 patients with revascularized HD for CLI and proposed prognosis amputation or death for patients with HD risk score (PAD for HD risk score). PAD for HD risk score (non-ambulation: 3 points, ulcer/gangrene: 2 points, GNRI<92: 2 points, CRP>0.3 mg/dl: 1 point, Age≥75: 1 point) is more accurate for the prediction of amputation or death than the PREVENT III risk score (area under the curve [AUC]: 0.79 [95% confidence interval: CI: 0.71-0.87], p<0.01 vs. AUC: 0.63 [95%CI: 0.56-0.71]). The patients were stratified into three groups by total score in ascending order. The rate of 1-year amputation-free survival and independent ambulatory status were significantly different among three groups. PAD for HD risk score is useful for rehabilitation planning in patients with HD and CLI. (This is a translation of J Jpn Coll Angiol 2016; 56: 85-91.).
