ABSTRACT
INTRODUCTION: Despite the importance of timing of nerve surgery after peripheral nerve injury, optimal timing of intervention has not been clearly delineated. The goal of this study is to explore factors that may have a significant impact on clinical outcomes of severe peripheral nerve injury that requires reconstruction with nerve transfer or graft. MATERIALS AND METHODS: Adult patients who underwent peripheral nerve transfer or grafting in Alberta were reviewed. Clustered multivariable logistic regression analysis was used to examine the association of time to surgery, type of nerve repair, and patient characteristics on strength outcomes. Cox proportional hazard regression analysis model was used to examine factors correlated with increased time to surgery. RESULTS: Of the 163 patients identified, the median time to surgery was 212 days. For every week of delay, the adjusted odds of achieving Medical Research Council strength grade ≥ 3 decreases by 3%. An increase in preinjury comorbidities was associated with longer overall time to surgery (aHR 0.84, 95% CI 0.74-0.95). Referrals made by surgeons were associated with a shorter time to surgery compared to general practitioners (aHR 1.87, 95% CI 1.14-3.06). In patients treated with nerve transfer, the adjusted odds of achieving antigravity strength was 388% compared to nerve grafting; while the adjusted odds decreased by 65% if the injury sustained had a pre-ganglionic injury component. CONCLUSION: Mitigating delays in surgical intervention is crucial to optimizing outcomes. The nature of initial nerve injury and surgical reconstructive techniques are additional important factors that impact postoperative outcomes.
ABSTRACT
BACKGROUND: Adjustment to college is critical for academic success. Poor college adjustment correlates with poor academic performance, low graduation rates, and poor success later in life. Limited data are available on the effects of inflammatory bowel disease (IBD) on college adjustment. We hypothesize that disease activity negatively impacts on QOL, and adversely affects college adjustment. METHODS: Undergraduate students (6 Crohn's disease [CD], 12 ulcerative colitis [UC], 19 healthy controls) completed a standardized college adjustment survey (SACQ) and QOL instrument (SF-12). Where appropriate, disease specific activity and QOL indices were obtained (HBI, SCCAI, SIBDQ). RESULTS: There was an inverse correlation between disease activity and college adjustment in CD and UC (R = -0.6554, p = 0.0032). IBD students had lower physical QOL (SF-12) than controls (p = 0.0009). Emotional domain of college adjustment correlated best with SIBDQ (R = 0.8228, p < 0.0001), and correlated better in CD (R = 0.8619) than UC (R = 0.7946). Mental QOL (SF-12) was worse in CD than UC (p = 0.0211), but neither differed from controls (p = 0.4, p = 0.6). CONCLUSIONS: Students with active Crohn's and colitis adjust less well to college life. Physical and emotional factors likely contribute. More aggressive medical therapy and better emotional support before and during college may result in happier and healthier college students, leading to higher graduation rates and future success. Interventions resulting in better disease control and support systems may improve college performance and provide long-term benefits to young adults with IBD.
