Sanitation and its Impact on the Bacteriological Quality of Water: A Study in Three Communities in Ghana
Water constitutes about 70% of the earth’s total mass and all life is dependent on water. Inadequate sanitation is a major cause of disease worldwide and improving sanitation is known to have a significant beneficial impact on health both in households and across communities. Water and sanitation are closely related and cannot be isolated. If uncontaminated water is available, reliable and convenient to collect, more water is consumed, both for hygienic purposes and for drinking which can improve health. In this study, the effect of sanitation on the bacteriological quality of water was evaluated. The study also assessed the sanitation facilities available in the three communities, the water facilities used and the bacterial contamination of household water. A cluster survey system was employed in three communities namely Tetegu, Mayera and Ashongman village in the Greater Accra Region of Ghana. Thirty households were clustered within each community. Within each household in each community, domestic water stored was analyzed for bacterial contamination using UriSelect 4 medium. This was used because it allows the isolation and counting of all organisms using a standard bacteriological loop plating method. Standardized questionnaires were administered in each household to ascertain the type of water and sanitation infrastructure. Seventy-seven percent and 87% of respondents relied on public standpipes in the Ashongman and Tetegu communities, respectively. Eightythree percent of respondents in Mayera relied on the Nsaki river. Eighty percent of respondents used the KVIP at Mayera, 97% of respondents at Tetegu resorted to open defecation, and 57% of respondents also used the pit latrine at Ashongman community. A total of ten bacterial species namely: Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterococcus faecalis, Proteus mirabilis, Streptococcus agalactiae. Enterobacter cloacae, Staphylococcus saprophytic, Candida albicans and Staphylococcus aureus were identified in domestic water stored. This study therefore recommends that policy makers must ensure the provision of basic infrastructure such as toilet facilities to reduce the likely contamination of water sources from poor sanitation facilities.Key words: Sanitation, Coliform, Households, Water Qualit
The physiology of growth hormone (GH) in adults: translational journey to GH replacement therapy
The fact that growth hormone (GH) plays an important role in health after the cessation of growth requiring replacement therapy in adult life has only been recognised in the last three decades. This has only been made possible by recombinant technology providing GH supplies required to undertake investigations in the physiology of GH action and the benefits of replacement therapy in patients identified by rigorously validated diagnostic tests for GH deficiency (GHD). Human studies have revealed important regulatory roles in substrate metabolism, sodium homeostasis, body composition, and physical function. GH-induced anabolism is achieved by stimulating amino acid incorporation into protein while reducing oxidative loss simultaneously enhancing lipid utilisation by stimulating fatty acid oxidation and reducing lipid storage. Sodium and fluid retention are enhanced by activating the renin-angiotensin system and distal renal tubular reabsorption. GH stimulates the aerobic and anaerobic energy systems that underpin muscle and cardiovascular function. These pleiotropic actions explain the clinical picture of increased adiposity, reduced lean mass, and impaired physical and psychological function in the GHD adult, all of which are reversed when GH is replaced. Women require a greater replacement dose of GH than men. This is because androgens enhance while oestrogens attenuate GH action. The oestrogen effect is route-dependent, occurring with oral delivery blunting the liver-mediated actions of GH by directly inhibiting GH receptor signalling, global experience spanning over 30 years has attested to the safety, efficacy, and benefits of replacement therapy for adults with GHD

Exposure to particulate air pollution at different living locations and respiratory symptoms in Hong Kong-an application of satellite information
Respiratory ill-health effects due to particulate air exposure at different geographical locations in Hong Kong that aggregate individual living locations were estimated based on satellite information. We assessed the presence of respiratory symptoms of a frequent cough or sputum in school students aged 11-20 years old (n=9,881). Daily particulate air pollution levels at students' living locations were derived from the surface extinction coefficients measured by satellite and measurements from the air pollutant monitoring stations at ground level. Adjusted odds ratio (OR) [95% CI] of respiratory symptoms was 1.047 [1.005, 1.091] per 10 g m-3 increase in PM10 concentration. Specificity tests showed that adjusted OR of having other symptoms is not significant (p=0.20-0.94). Exposures to PM10 at different geographical locations is associated with increased odds of having respiratory symptoms (cough or sputum) but not with other symptoms unrelated to air pollution. © 2010 Taylor & Francis.postprin
