The African yam bean (Sphenostylis stenocarpa Hochst ex A. Rich) is a leguminous crop found in the Volta Region of Ghana. Three expeditions were undertaken in the region between September 1998 and March 1999 to investigate the extent of cultivation and use of the bean as the basis for research into its development and promotion as a major crop. Its cultivation is currently localized around Nkwanta and Ho West Districts. It is grown as a minor crop in mixed association with yam and cassava. It is used extensively in various dietary preparations and has potential for supplementing the protein requirements of many families throughout the year. Its current low status as a minor crop means that this potential is largely unexploited. Research efforts are required to improve its agronomic characteristics and promote its cultivation and use as a major crop.

BackgroundAlthough breastfeeding of infants is recommended globally, the fact that maternal toxic metal stores are mobilised into breast milk implies infants, whose mothers live and work in mining communities, are at risk of multiple exposure to mining related toxic metals, such as Lead (Pb), Mercury (Hg), Cadmium (Cd) and Arsenic (As), through breast milk intake, in addition to in utero exposure.MethodA total of 114 mother-baby pairs, recruited from two community hospitals servicing mining communities in two different regions in Ghana (57 each), were involved in this study. When the babies were 3 months old, the amount of breast milk intake, concentrations of selected toxic metals in the breast milk and therefore the amount of toxic metals exposure through breast milk were determined. The study also, determined the amount of these toxic metals in the hair and urine of each mother-baby pair at 3 months postpartum.ResultsBased on the amounts of milk intake and non-milk oral intakes (geometric mean of 0.701 (95% CL 0.59–0.81) Kg/day and median of 0.22 Kg/day respectively), 90% of the babies were determined to have been exclusively breastfed. The amounts of most of the toxic metals in breast milk were higher than the WHO set limits and for 46.4%, 33.3% and 4.4% of the babies, their intake of As, Hg and Pb respectively were above the WHO provisional tolerable daily intake (PTDI) values.ConclusionAn appreciable proportion of babies living within the communities served by the Mangoasi Community Hospital in the Obuasi Municipality of the Ashanti Region and the Dompime Health Centre in the Tarkwa Municipality of the Western Region were exposed to Hg, As and Pb through breast milk in excess of what they should and these may have health implication for the infants and therefore calls for interventions.

Background: The amounts of micronutrients in the diets of infants, and the factors that influence them needs to be monitored at the population level in order to avert detrimental developmental defects that impose lifetime-limitations on an infant's regulatory and defense systems. This study therefore, sought to evaluate if increasing levels of the toxic metals, Hg, Pb and Cd in breast milk will result in reducing amounts of the micronutrients Zn, Se and Cu in breast milk. Methods: Breast milk samples of 114 women living in two mining areas (57 women each) in Ghana, whose babies' amounts of breast milk intake at three months postpartum, and amounts of toxic metals had previously been determined in a prospective study, were analyzed for micronutrients by a combination of acid and microwave digestion, and quantifications were by two different modes (hydrogen and helium) of Octapole Reaction System Inductively Coupled Plasma Mass Spectrometer (7500 ce. Agilent), equipped with an ASX-510 Auto-sampler (Cetac). Results: All the breast milk specimen collected contained detectable amounts of Cu, Zn, both at levels less than have been previously reported, and Se. For specimen that did not contain Pb the amount of Se ranged from about 110 to 245 ng/g of milk, however, as the amount of Pb increased, the corresponding highest detected amount of Se reduced steeply, resulting in a right-angle triangle-shaped scatter plot. Similar relationships were observed between other toxic metals and micronutrients studied. A curve fitting regression analysis showed significant qua

Human Immunodeficiency Virus (HIV) is RNA virus that causes Acquired Immune Deficiency Syndrome (AIDS). In Ghana the AIDS epidemic is spreading very fast in densely populated areas with higher numbers of cases occurring in the southern regions especially the densely populated capitals such as Kumasi, Koforidua and Accra as well as mining towns like Obuasi and Tarkwa, and in border towns. Data was collected from Accra and Kumasi on socioeconomic backgrounds such as age, sex, education, marital status, household size, among others with a structured questionnaire and analysed using statistical Package for Social Sciences (SPSS) version 16.0 About 72% females and 28% males were interviewed with close to 74% lying between 22 to 40 age brackets. Also 63% of these completed JHS/Middle school, Seventeen (36.1%) are married people, 15 (31.9%) widowed. Majority of them are Akans who are also Christians with different denominations. Among these people, 20 (42.6%) of them are unemployed, and 3 (6.4%) claimed to be self-employed in various disciplines. Most of them said they use condoms as contraceptives in order to prevent the spread of the disease. Income level of the respondents predominantly lies between GH¢50.00-GH¢450.00 per annum. Some of the interventions for preventing the disease include promoting abstinence and faithfulness, promoting reductions in the number of sexual partners, encouraging delays in the onset of sexual activity among others.
