A comparison of condition factor and gona dosomatic index of sardine Sardinops sagax stocks in the northern and southern Benguela upwelling ecosystems, 1984–1999

Time-series of condition factor (CF) and gonadosomatic index (GSI) were generated using general linear models (GLM) for sardine Sardinops sagax stocks in the northern and southern Benguela ecosystems over the period 1984–1999. During this period the biomass of sardine in the northern Benguela remained at relatively low levels of African Journal of Marine Science 2001, 23: 123–13

Holistic Health, Disadvantage, Higher Education Access and Success: A Reflection

The objective of this article is to reflect upon the relationships amongst health, disadvantage, educational opportunities, and higher education access and success. This is a reflective article taken from the literaturereview of a doctoral study on the relationship between health, access to, and success within, higher education. The importance of health in education and the practical implementation of programmes resulting in enhanced health and academic success amongst higher education students is reviewed.  Literature for the doctoral study on which this reflection was based was sourced predominantly from Pub-Med Central, the U.S. National Institute of Health National Library of Medicine and The South African South-East Academic Library Services. From this discussion, the rationale for a holistic health promotion programme within the higher education setting, for students from socioeconomically deprived backgrounds, is given. The problem of educational failure of students from socioeconomically disadvantaged backgrounds in higher education could be lessened by instituting a holistic health promotion programme within the first year of study. Evidence suggests that such a programme would have both health and educational advantages

Herpes simplex virus type 1 and normal protein permeability in the lungs of critically ill patients: a case for low pathogenicity?

INTRODUCTION: The pathogenicity of late respiratory infections with herpes simplex virus type 1 (HSV-1) in the critically ill is unclear. METHODS: In four critically ill patients with persistent pulmonary infiltrates of unknown origin and isolation of HSV-1 from tracheal aspirate or bronchoalveolar lavage fluid, at 7 (1-11) days after start of mechanical ventilatory support, a pulmonary leak index (PLI) for 67Gallium (67Ga)-transferrin (upper limit of normal 14.1 x 10(-3)/min) was measured. RESULTS: The PLI ranged between 7.5 and 14.0 x 10(-3)/min in the study patients. Two patients received a course of acyclovir and all survived. CONCLUSIONS: The normal capillary permeability observed in the lungs argues against pathogenicity of HSV-1 in the critically ill, and favors that isolation of the virus reflects reactivation in the course of serious illness and immunodepresssion, rather than primary or superimposed infection in the lungs
