Pain Deterioration Within 1 Year Predicts Future Decline of Walking Ability: A 7-Year Prospective Observational Study of Elderly Female Patients With Knee Osteoarthritis Living in a Rural District

Introduction: Knee osteoarthritis (KOA) is commonly a main cause of locomotive syndrome. Consequently, appropriate timing of intervention is clinically important. Materials and Method: Fifty female patients of a primary care clinic in a rural district fulfilled the criteria for KOA and were recruited and underwent knee medical checkups. They initially underwent physical examination bilaterally of knees by an orthopedic surgeon, radiological evaluation, and they answered the outcome of Japanese Knee Osteoarthritis Measurement (JKOM). They were asked to answer JKOM 1 and 7 years after the initial checkup. Fourteen patients were lost to follow-up due to death or moving to a nursing home. Thirty-six patients were finally included and divided into 2 age-matched groups according to walking ability at the 7-year follow-up: group A, walking ability did not decline (n = 24), and group B, walking ability did decline (n = 12). The walking ability was measured as per ordinal classification as: 5 (walking without any aid), 4 (walking with a crutch), 3 (walking using walker), 2 (walking only possible in parallel bars), and 1 (wheelchair). We completed between-group comparisons of each of the 3 subsections of the JKOM (pain, limitation in mobility related to daily activity, and restriction of participation in social life and health perception), during each period. Results: There were significant differences in JKOM pain score (12.9 vs 18.3, P = .0058) and total score (41.3 vs 55.8, P = .0093) between the groups at 1-year follow-up, even though base scores did not differ. Discussion: Clinicians should pay attention to changes in perceived knee pain and should not continue prolonged conservative therapy in patients exhibiting rapid deterioration. Conclusion: Female patients with KOA whose pain deteriorated within 1 year may require early intervention to prevent future decline in walking ability

Impact of Endoscopic Surgical Skill Qualification on Laparoscopic Resections for Rectal Cancer in Japan: The EnSSURE Study

Objective:. This cohort study investigated short- and long-term postoperative outcomes of laparoscopic procedures for rectal cancer performed with versus without certified surgeons. Background:. In Japan, the Endoscopic Surgical Skill Qualification System (ESSQS) evaluates surgical skills deemed essential for laparoscopic surgery; however, it is unknown whether this certification contributes to procedural safety. Methods:. Outcomes of laparoscopic rectal resections for cStage II and III rectal cancer performed from 2014 to 2016 at 56 Japanese hospitals were retrospectively reviewed. The impact of having versus not having certified surgeons on postoperative complications and other short- and long-term outcomes were assessed. In cases with ESSQS-certified surgeons, surgeons attended surgery in the capacity of an operator, assistant, scope operator, or advisor. Results:. Overall, 3188 procedures were analyzed, with 2644 procedures performed with and 544 without ESSQS-certified surgeons. A multivariate logistic regression model showed that the adjusted odds ratio of postoperative complications after procedures performed with ESSQS-certified surgeons was 0.68 (95% confidence interval, 0.51–0.91; P = 0.009). The adjusted odds ratios for conversion and pathological R0 resection rates with ESSQS-certified surgeons were 0.20 (P < 0.001) and 2.10 (P = 0.04), respectively. Multiple linear regression analyses showed significantly shorter surgical duration and more harvested lymph nodes for operations performed with ESSQS-certified surgeons. Multivariate Cox regression showed that the adjusted hazard ratios for poor overall and recurrence-free survival after operations performed with ESSQS-certified surgeons were 0.88 (P = 0.35) and 1.04 (P = 0.71), respectively. Conclusions:. This study showed the superiority of the short-term postoperative results for laparoscopic rectal procedures performed with ESSQS-certified surgeons
