Prevalence of Low Back Pain among Adolescent Students in a Nigerian Urban Community

This school-based survey was aimed at determining the prevalence of low-back pain (LBP) among adolescent students of selected secondary schools in Ibadan, Nigeria. Nine hundred secondary schools students, comprising 415 boys and 485 girls, with age range 12-17 years were surveyed. They were required to complete a self-developed, three-part items questionnaire which collected information on socio-demographic characteristics, history and intensity of low back pain, factors predisposingto low back pain, and activity limitations suffered because of low back pain.The 12-month and point prevalence of LBP among participants were 40.7% and 12.9% respectively. For boys the 12-month prevalence of LBP was 41.7% and for girls it was 39.8%. The point prevalence of LBP was14.2% for girls and 11.3% for boys. Most of the participants had their first LBP experience at 10-15 years, with a peak at 12-14 years. The LBP experienced by most participants was of short duration and only a few episodes, suggesting non-chronicity. Over 50% of the participants were involved in activities that make them frequently bend at the waist.The findings of this survey suggest that LBP is fairly prevalent among Nigerian adolescents. Health education on LBP prevention will help reduce its incidence in this population.KEYWORDS: low back pain, prevalence, adolescent students, Nigeri

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

AimThe SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery.MethodsThis was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin.ResultsOverall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P ConclusionOne in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease
