An epidemiological perspective of substance use among high school pupils in rural KwaZulu-Natal
Objectives. To investigate prevalence and the factors influencing substance use among rural high school pupils in KwaZulu-Natal in order to develop and implement intervention programmes.Design. Cross-sectional study.Setting. Twenty-eight high schools in southern KwaZulu-Natal.Subjects. One thousand three hundred and eighteen grade 10 pupils.Outcome measures. An anonymous self-reporting questionnaire was used to investigate the use of alcohol, tobacco (cigarettes), cannabis and solvents.Results. Of the male scholars, 52.9% (95% confidence interval (CI): 45.4- 60.3) reported ever using alcohol, 16.9% (CI: 11.5 - 24.0) reported using cannabis, and 13.1% (CI: 7.2 - 22.5) had smoked more than one cigarette daily. Among male pupils 45.5% (CI: 38.6- 52.6) had inhaled benzine and 34.6% (CI: 28.0- 41.8), thinners; 7.4% (CI: 3.4 - 15.2) had used cocaine and 4.1% (CI: 1.0 - 10.6), crack. Female pupils reported significantly less use of alcohol (25.5%, CI: 17.6 - 35.3), cannabis (2.3%, CI: 1.3 - 4.1), cigarettes (more than one daily) (2.0%, CI: 1.0 - 4.1), and inhalation of benzine (18.8%, CI: 13.8 - 25.2) and thinners (10.8%, CI: 7.2 - 16). Logistical regression indicated that the odds of smoking cigarettes increased significantly (p < 0.0005) with use of the other substances.Conclusion. The results of this study confirm the prevalence of multi-substance use among pupils at the majority of rural high schools in this district and the need for targeted interventions to reduce/prevent this

Schistosomiasis knowledge, attitude, practices, and associated factors among primary school children in the Siphofaneni area in the Lowveld of Swaziland
Background: Schistosomiasis, a worldwide concern, has received attention in Swaziland through control programs such as deworming programs, education programs, and school health programs; however, these programs neglect the importance of monitoring and evaluation strategies such as assessing children's knowledge, attitudes and practices (KAPs) and the prevalence of the disease. Children are a high-risk group because of their water contact practices, and need to be informed about schistosomiasis to influence their attitudes and practices. Social and cultural factors are involved in schistosomiasis control because they instill myths and misconceptions about the disease. As a result, children in the community may be comfortable with bad practices. This study aimed to assess the KAPs of schoolchildren on schistosomiasis, and to identify practices that support or hinder the progress of schistosomiasis control.
Methods: In 2014, a descriptive quantitative cross-sectional survey was conducted through questionnaires among Siphofaneni primary schools, an area hit by schistosomiasis in the Lowveld of Swaziland. A logistic regression model was applied to analyze the data.
Results: Moderate knowledge, good attitudes, and fairly good practices were observed in the children. However, practices of certain children were risky and they still had some misconceptions. Knowledge was correlated with practice and with predictors of good and bad practices such as male sex, always urinating in water, and always using river water for domestic practices.
Conclusion: This study suggests that empowering children with knowledge and attempting to modify their water contact, and improved human waste disposal practices are necessary for schistosomiasis control

The ASOS Surgical Risk Calculator: development and validation of a tool for identifying African surgical patients at risk of severe postoperative complications
Background:
The African Surgical Outcomes Study (ASOS) showed that surgical patients in Africa have a mortality twice the global average. Existing risk assessment tools are not valid for use in this population because the pattern of risk for poor outcomes differs from high-income countries. The objective of this study was to derive and validate a simple, preoperative risk stratification tool to identify African surgical patients at risk for in-hospital postoperative mortality and severe complications.
Methods:
ASOS was a 7-day prospective cohort study of adult patients undergoing surgery in Africa. The ASOS Surgical Risk Calculator was constructed with a multivariable logistic regression model for the outcome of in-hospital mortality and severe postoperative complications. The following preoperative risk factors were entered into the model; age, sex, smoking status, ASA physical status, preoperative chronic comorbid conditions, indication for surgery, urgency, severity, and type of surgery.
Results:
The model was derived from 8799 patients from 168 African hospitals. The composite outcome of severe postoperative complications and death occurred in 423/8799 (4.8%) patients. The ASOS Surgical Risk Calculator includes the following risk factors: age, ASA physical status, indication for surgery, urgency, severity, and type of surgery. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.805 and good calibration with c-statistic corrected for optimism of 0.784.
Conclusions:
This simple preoperative risk calculator could be used to identify high-risk surgical patients in African hospitals and facilitate increased postoperative surveillance.
