Soil and Water Assessment Tool, (SWAT) model was used to predict the impacts of Climate Change on Ajali River watershed, Aguobu-Umumba, Ezeagu, Enugu State, Nigeria. The model was first used to simulate stream flow using observed data. After model run, parameterization, sensitivity analysis, the monthly coefficients of determination (R 2 ) were 0.5739 and 0.6776 for calibration and validation respectively. Having performed fairly well, the model was thereafter run to simulate climate change impacts on streamflow. Two GCMs -CCCMA and GFDL, were used to generate future climate data and run in SWAT. Total observed streamflow for the baseline (1981-2000) was compared with that predicted (2046 -2064) from the GCMs. The results of the CCCMA models showed an increase of 383.72m 3 /s and 2.1% in the streamflow of the Ajali river watershed when projected to 2046 -2064 as against the historical baseline while GFDL showed 3358.58 m 3 /s and 18.9% respectively. The study, when applied, will help watershed managers and planners in the management of the watershed for effectiveness and efficiency. It will also increase our awareness of the effect of climate change on other water bodies in the hinterlands.
Hernias are common in children and account for most of the surgical operations performed by the Paediatric surgeons. They often present late in resource-poor countries for a variety of reasons. In these settings, surgical outreaches reduce the burden of hernias. We aim to determine the effectiveness of a tertiary hospital-based surgical outreach for hernia repair in children in a low-resource-setting. We did a prospective study conducted during a surgical outreach carried out over seven days at a tertiary center in Southeast Nigeria. Recruited subjects were physically examined to establish a diagnosis and screened for fitness before surgeries were performed. Data were collected using a structured proforma to information from the patient's case-notes. Data analysis was done using the statistical package for social sciences (SPSS) version 25. There were 77 children with 80 hernia surgeries, 71 (92.2%) males, and 6 (7.8%) females (ratio of 12:1) were involved. The majority (66.2%) were aged 2-12years and were mainly rural dwellers. Right groin hernias were present in 54.5% and 40.3% had left groin hernias. Herniotomy was the main procedure offered (93.5%). The complication rate was 9.1%. Senior registrars in surgery (Senior trainee surgeons) participated in most of the operations. The mean duration of surgery was 34.9 + 17.6 minutes. Surgical outreach in tertiary hospital for hernias in children in resource-poor settings offers the opportunity for mass repairs with good outcomes. It provides a hands-on opportunity for trainee surgeons to improve their mastery of hernia surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
