Serum lipid and lipoprotein levels in Ghanaians with diabetes mellitus and hypertension.

Both diabetes mellitus and hypertension alter lipid and lipoprotein metabolism and increase the risk of coronary artery disease. We have reported previously on lipid and lipoprotein levels in healthy Ghanaians, and this study deals with the levels of these biochemical parameters in Ghanaians with diabetes mellitus and hypertension. Fasting serum lipoproteins were determined on blood samples drawn from healthy male and female Ghanaians as well as age-matched individuals with either diabetes or hypertension. Cholesterol, high-density lipoprotein cholesterol (HDL-C), triglycerides, and fasting blood glucose were measured. Low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) were derived. Total serum cholesterol levels were 4.43 +/- 0.22 mmol/L and 4.67 +/- 0.26 mmol/L for diabetic males and females, respectively. High-density lipoprotein was 1.55 +/- 0.09 mmol/L and 1.50 +/- 0.09 mmol/L for male and female diabetics, respectively. Lipid and lipoprotein levels in the hypertensive patients did not differ from the above values. The levels of cholesterol and lipoprotein obtained in Ghanaians with hypertension and diabetes mellitus were similar to those of their age-matched healthy controls. These results suggest a reduced risk of coronary artery disease from the atherogenic effects of cholesterol in Ghanaians with diabetes mellitus and hypertension.     

Loops and Building Blocks: a Knowledge co-Production Framework for Equitable Urban Health

This paper sets out a structured process for the co-production of knowledge between researchers and societal partners and illustrates its application in an urban health equity project in Accra, Ghana. The main insight of this approach is that research and knowledge co-production is always partial, both in the sense of being incomplete, as well as being circumscribed by the interests of participating researchers and societal partners. A second insight is that project-bound societal engagement takes place in a broader context of public and policy debate. The approach to co-production described here is formed of three recursive processes: co-designing, co-analysing, and co-creating knowledge. These ‘co-production loops’ are themselves iterative, each representing a stage of knowledge production. Each loop is operationalized through a series of research and engagement practices, which we call building blocks. Building blocks are activities and interaction-based methods aimed at bringing together a range of participants involved in joint knowledge production. In practice, recursive iterations within loops may be limited due of constraints on time, resources, or attention. We suggest that co-production loops and building blocks are deployed flexibly.     

Managing HIV-positive sero-status in Ghana’s most HIV concentrated district: self-perceived explanations and theoretical discourse

As of December 2015 there were 37 million persons living with HIV/AIDS (PLWHAs), 70% of whom are in sub-Saharan Africa. Ghana, which contributes a relatively small number to Africa’s HIV burden, has a generalised HIV epidemic. The current national prevalence is 1.47%. Agormanya, one of the HIV sentinel sites in the county and where this study was conducted, has current prevalence of 11.6%. This makes it critical to explore how persons infected with HIV manage their lives, especially in the midst of entrenched stigma and discrimination. However, available information on how PLWHAs in sub-Saharan Africa handle their day-to-day lives mostly dwell on food and nutrition. Thus, there is dearth of information on how PLWHAs in Ghana particularly handle the circumstances of their daily lives which are mostly coloured by their HIV-positive statuses, given their stigmatised identity. We explore how PLWHAs respond to the experiences and challenges of living with HIV/AIDS in Lower Manya Krobo, consistently most HIV-infected district in Ghana. Data were collected from 38 combined purposive and randomly selected HIV-positive persons in two leading hospitals (St Martins Depores Agormanya and Atua Government hospitals which provide specialised HIV care in the district. Using in-depth interviews, we studied how PLWHAs managed their routine livelihoods in the midst of extreme stigma. We combined the social capital and resilience theoretical frameworks to show that our respondents were mostly resilient and strategically mostly drew upon extended family social support to cope with their livelihood challenges. We recommend that community opinion leaders and other stakeholders sensitise community members in Lower Manya Krobo to better understand the mode of HIV infection and encourage/strengthen family and community cohesion and social support.     

Two sulfonate metabolites of physalin A in rats

1.?Physalin A is a bioactive withanolide isolated from the natural plant Physalis alkekengi var. franchetii (Solanaceae), a common traditional Chinese herbal medicine. This study aims to investigate the metabolites of physalin A in vivo.

2.?Two metabolites (M1 and M2) were characterized as sulfonate metabolites in the feces obtained from rats treated with physalin A orally at a dose of 15?mg/kg/day for 3 days, by application of a UPLC-Q/TOF-MS method. Furthermore, formation of the two sulfonate metabolites was verified by chemical synthesis and NMR, including ¹H NMR, ¹³C NMR and two-dimensional NMR. The structures of M1 and M2 were identified to be 3α-sulfo-2,25β,27-trihydrophysalin A and 3α,27-disulfo-2,25α-dihydrophysalin A, respectively.

3.?In summary, this study indicated that physalin A could be biotransformed to sulfonate metabolites with strong polarity, which contributed to the elimination of physalin A. A rare metabolic pathway has been revealed in this study.
