Author N. Naicker, P. de Jager, S. Naidoo and A. Mathee Source Int. J. Environ. Res. Public Health 2018, 15, 1427; doi:10.3390ijerph15071427 Summary Abstract: Lead exposure has been associated with psycho-neurological disorders. Elevated blood lead levels have been found in shooters. This study assesses the association between the blood lead levels of shooters and their levels of aggression. An analytical cross-sectional study was conducted in Gauteng, South Africa. Participants were recruited from four randomly selected shooting ranges with three randomly […]

Efficacy assessment of ultraviolet germicidal irradiation (UVGI) devices for inactivating airborne Mycobacterium tuberculosis

Author T. Singh, Z. Ngcobo, O. Kgasha, W. Leuschner, O. Matuka, T. van Reenen, P. de Jager Source Occupational Health Southern Africa. Vol 24 No 4; July/ August 2018 Summary Introduction: Airborne transmission of Mycobacterium tuberculosis (TB) and other infectious agents within indoor environments has been a recognized hazard for decades. The increasing incidence of airborne diseases and drug resistance has renewed interest in ultraviolet germicidal irradiation (UVGI) to reduce transmission. The aim of this study was to determine the […]

Drivers of international variation in prevalence of disabling low back pain: Findings from the cultural and psychosocial influences on disability study

Author D. Coggon, G. Ntani, KT Palmer, VE Felli, F. Harari, LA Quintana, et al. Source European Journal of Pain. 2018. DOI: 10.1002/ejp.1255 Summary Background: Wide international variation in the prevalence of disabling low back pain (LBP) among working populations is not explained by known risk factors. It would be useful to know whether the drivers of this variation are specific to the spine or factors that predispose to musculoskeletal pain more generally. Methods: Baseline information about musculoskeletal pain and […]

Blood biochemical and hematological study after subacute intravenous injection of gold and silver nanoparticles and coadministered gold and silver nanoparticles of similar sizes

Author JH Lee, M. Gulumian, EM Faustman, T. Workman, K. Jeon and IJ Yu Source BionMed Research International 2018 Summary Background: Background: To investigate the effect of subacute intravenous administration AgNP (silver nanoparticles, 10 nm) and AuNP (gold nanoparticles, 12.8 nm) and AgNP/AuNP mixture to blood biochemistry, hematology, and platelet coagulation, subacute toxicity study was conducted. Methods: AuNP and AgNP in which their size distribution was not statistically different, mixed or separate, were injected into the caudal vein of male […]
