The global drug trade and its associated violence, corruption, and human suffering create global problems that include political and military conflicts, ethnic minority human rights violations, and stresses on economic development. Drug production and eradication affects the stability of many states, shaping and sometimes distorting their foreign policies. External demand for drugs has transformed many indigenous cultures from using local agricultural activity to being enmeshed in complex global problems. Dangerous Harvest presents a global overview of indigenous peoples' relations with drugs. It presents case studies from various cultural landscapes that are involved in drug plant production, trade, and use, and examines historical uses of illicit plant substances. It continues with coverage of eradication efforts, and the environmental impact of drug plant production. In its final chapter, it synthesizes the major points made and forecasts future directions of crop substitution programs, international eradication efforts, and changes in indigenous landscapes. The book helps unveil the farmer, not to glamorize those who grow drug plants but to show the deep historical, cultural, and economic ties between farmer and crop.

Manual wheelchair use may determine shoulder joint overload and rotator cuff injury. Chronic shoulder pathologies can also influence the propulsion ability of wheelchair athletes with spinal cord injury (SCI) during sport activities. However, the relationship between shoulder pathology and wheelchair performances has never been explored. Therefore, the study aimed to investigate the correlation between shoulder pathologic findings with clinical tests and ultrasonography evaluation and the results of wheelchair performance tests. Nineteen quadriplegic wheelchair rugby players were evaluated to investigate the association between clinical and ultrasound shoulder pathologic findings and their correlation with the performance of field-based selected wheelchair skills tests (WSTs). The outcome measures were the International Wheelchair Rugby Classification Score, dominant and non-dominant Physical Examination Shoulder Score, and dominant and non-dominant Ultrasound Shoulder Pathology Rating Scale (USPRS). The WST was measured at the beginning and at one-year follow-up. A statistically significant correlation was found between the time since SCI and dominant USPRS (p < 0.005). The non-dominant USPRS was strongly related to WST at the beginning (p < 0.005) and the end of the study (p < 0.05). Data suggest that the severity of the non-dominant shoulder pathology detected on the ultrasound is related to lower performance on the WST. Chronic manual wheelchair use could be responsible for dominant SCI shoulder joint and rotator cuff muscle damage, while non-dominant USPRS could be related to performance on the WST.

IntroductionApproximately 80% of people with spinal cord injury experience clinically significant chronic pain. Pain (whether musculoskeletal or neuropathic) is consistently rated as one of the most difficult problems to manage and negatively affects the individual’s physical, psychological and social functioning and increases the risk of pain medication misuse and poor mental health. The aim of this study is to therefore determine the presence of pain and its impact on functioning and disability as well as to develop a framework for self-management of pain for South African manual wheelchair users with spinal cord injury.Methods and analysisCommunity-dwelling participants with spinal cord injury will be invited to participate in this three-phase study. Phase 1 will use a quantitative, correlational design to determine factors related to pain such as pectoralis minor length, scapular dyskinesis, wheelchair functioning, physical quality of life, community reintegration and pain medication misuse. Demographic determinants of pain such as age, gender, type of occupation, completeness of injury and neurological level of injury will also be investigated. Participants with pain identified in phase 1 will be invited to partake in a qualitative descriptive and contextually designed phase 2 to explore their lived experience of pain through in-depth interviews. The results of phases 1 and 2 will then be used with the assistance from experts to develop a framework for self-management of pain using a modified Delphi study. Data analysis will include descriptive and inferential statistics (quantitative data) and thematic content analysis (qualitative data).Ethics and disseminationApproval for this study is granted by the Faculty of Health Sciences Research Ethics Committee of the University of the Pretoria (approval number 125/2018). This study is registered with the South African National Health Research Database (reference GP201806005). This study’s findings will be shared in academic conferences and published in scientific peer-reviewed journals.
