Abstract

Over the last 2 decades, many African countries have undergone dietary and nutrition transitions fueled by globalization, rapid urbanization, and development. These changes have altered African food environments and, subsequently, dietary behaviors, including food acquisition and consumption. Dietary patterns associated with the nutrition transition have contributed to Africa's complex burden of malnutrition—obesity and other diet-related noncommunicable diseases (DR-NCDs)—along with persistent food insecurity and undernutrition. Available evidence links unhealthy or obesogenic food environments (including those that market and offer energy-dense, nutrient-poor foods and beverages) with suboptimal diets and associated adverse health outcomes. Elsewhere, governments have responded with policies to improve food environments. However, in Africa, the necessary research and policy action have received insufficient attention. Contextual evidence to motivate, enable, and create supportive food environments in Africa for better population health is urgently needed. In November 2020, the Measurement, Evaluation, Accountability, and Leadership Support for Noncommunicable Diseases Prevention Project (MEALS4NCDs) convened the first Africa Food Environment Research Network Meeting (FERN2020). This 3-d virtual meeting brought researchers from around the world to deliberate on future directions and research priorities related to improving food environments and nutrition across the African continent. The stakeholders shared experiences, best practices, challenges, and opportunities for improving the healthfulness of food environments and related policies in low- and middle-income countries. In this article, we summarize the proceedings and research priorities identified in the meeting to advance the food environment research agenda in Africa, and thus contribute to the promotion of healthier food environments to prevent DR-NCDs, and other forms of malnutrition.

Abstract

Abstract Background Buruli ulcer (BU), a neglected tropical skin disease caused by Mycobacterium ulcerans, has been reported in over 30 countries worldwide and is highly endemic in rural West and Central Africa. The mode of transmission remains unknown and treatment is the only alternative to disease control. Early and effective treatment to prevent the morbid effects of the disease depends on early diagnosis; however, current diagnosis based on clinical presentation and microscopy has to be confirmed by PCR and other tests in reference laboratories. As such confirmed BU diagnosis is either late, inefficient, time consuming or very expensive, and there is the need for an early diagnosis tool at point of care facilities. In this paper we report on a simple, quick and inexpensive diagnostic test that could be used at point of care facilities, in resource-poor settings. Methods The methodology employed is based on the loop mediated isothermal amplification (LAMP) technique. Four sets of Primers, targeting the mycolactone encoding plasmid genome sequence of M. ulcerans were designed. The BU-LAMP assay was developed and tested on five M. ulcerans strains from patients in Ghana and two American Type Culture Control (ATCC) reference isolates; Ghana #970321 (D19F9) and Benin #990826 (D27D14). We also tested the assay on other closely related, mycolactone-producing mycobacterial strains; M. marinum 1218, M. marinum DL240490, M. liflandii and M. pseudoshotsii, as well as experimentally infected laboratory animal and clinical samples. Results The results revealed a high specificity of the BU-LAMP assay for selectively detecting M. ulcerans. Compared to the conventional IS-2404 PCR, the new assay is cheaper and simpler and ten times more sensitive. Test results can be obtained within 1 hour. Conclusions This study indicates that the BU-LAMP assay could be suitable for early disease diagnosis and application in low-resource health facilities.

Abstract

Buruli ulcer (BU) is a skin disease caused by Mycobacterium ulcerans. Surgery is the main treatment option because antibiotics have mostly been ineffective. However, there are reports of successful treatment with undisclosed herbal preparations. This study screened 44 herbal preparations for (i) inhibitory activity against 7 M. ulcerans isolates, (ii) determined the minimum inhibitory concentrations (MICs) of 10 herbal preparations and (iii) screened them for extended antimicrobial activity, since BU is often associated with secondary bacterial infections. Twenty-five of the herbal preparations inhibited the growth of the M. ulcerans isolates. MICs of the 10 herbal preparations were between 0.20 and 12.50% volume/volume (1:128-1:2), and all 10 demonstrated extended antimicrobial activity. The findings (i) indirectly confirmed the claims that BU is being successfully treated with herbal preparations and (ii) suggest that the treatment of BU with herbal preparations might simultaneously treat secondary bacterial and fungal infections. In conclusion, there are a number of herbal preparations with anti-M. ulcerans activity, therefore there is the need to pay more attention to herbal therapy as a potential BU treatment option.

Abstract

Buruli ulcer (BU) is the third most prevalent mycobacteriosis, after tuberculosis and leprosy. The currently recommended combination of rifampicin-streptomycin suffers from side effects and poor compliance, which leads to reliance on local herbal remedies. The objective of this study was to investigate the antimycobacterial properties and toxicity of selected medicinal plants. Sixty-five extracts from 27 plant species were screened against Mycobacterium ulcerans and Mycobacterium smegmatis, using the Resazurin Microtiter Assay (REMA). The cytotoxicity of promising extracts was assayed on normal Chang liver cells by an MTT assay. Twenty five extracts showed activity with minimal inhibitory concentration (MIC) values ranging from 16 μg/mL to 250 μg/mL against M. smegmatis, while 17 showed activity against M. ulcerans with MIC values ranging from 125 μg/mL to 250 μg/mL. In most of the cases, plant extracts with antimycobacterial activity showed no cytotoxicity on normal human liver cells. Exception were Carica papaya, Cleistopholis patens, and Polyalthia suaveolens with 50% cell cytotoxic concentrations (CC50) ranging from 3.8 to 223 μg/mL. These preliminary results support the use of some West African plants in the treatment of Buruli ulcer. Meanwhile, further studies are required to isolate and characterize the active ingredients in the extracts. [ABSTRACT FROM AUTHOR]

Abstract

Objective: Hypercholesterolemia is the greatest risk factor for cardiovascular diseases. The present study is conducted to evaluate the lipid lowering activity of leaves and fruits of Solanum macrocarpon, a vegetable, on Wistar rats experimentally rendered hypercholesterolemic by Triton X-100. Materials and Methods: The leaves and fruits were administered (p.o.) for 7 days to rats at doses of 400 and 800 mg/kg of body weight. Atorvastatin was used as reference treatment drug. The data were analyzed by the Brown-Forsythe ANOVA, Dunnett's T3 multiple comparison test, and Dunnett's t test. All tests were done at the 5% significance level. Results: Administration of S. macrocarpon (fruits as well as leaves) resulted in a statistically significant decrease in total cholesterol, LDL-cholesterol, VLDL-cholesterol, and triglycerides in the treated groups compared with the untreated hypercholesterolemic group, regardless of the administrated doses. A significant increase in HDL-cholesterol was observed in the treated groups. Hepatic disorders due to the Triton have been corrected by S. macrocarpon. Conclusions: This vegetable effectively suppresses experimental hypercholesterolemia in Wistar rats, suggesting a protective role in cardiovascular diseases. Its use by individuals at risk should be promoted. [ABSTRACT FROM AUTHOR]

Abstract

Context: Phyllanthus niruri L. (Euphorbiaceae), a medicinal plant traditionally known for dissolving kidney stones, is used prophylactically as an antimalarial agent. Objective: The study was undertaken to determine its effect on some male hormones and other toxicological properties due to paucity of its data despite its wide use. Material and methods: Male Sprague-Dawley rats (100-140 g) were used. Group 1 [control group (C), n = 6] received water. Group 2 [low-dose test group (LD), n = 6] received 50 mg/kg body weight (b.wt.) aqueous leaf extract orally. Group 3 [high-dose test group (HD), n = 6] received 500 mg/kg b.wt. extract for 90 days. Upon sacrifice, among other organs the testes were harvested. Blood samples drawn were used for biochemical (including progesterone, estrogen and testosterone), cytotoxicity and hematological assays. Results: C, LD and HD estrogen values were 192 ± 25, 385 ± 122 and 962 ± 357 pg/ml, respectively. In the same order, progesterone values were 96 ± 24, 155 ± 45 and 320 ± 80 pg/ml, respectively. Testosterone levels were 5210 ± 1090, 4710 ± 220 and 4500 ± 580 pg/ml, respectively. Significant differences were observed in the estrogen and progesterone levels ( p = 0.001). Degenerative changes were observed histologically. Cytotoxicity at 50% (CC50) was 10.0 µg/ml. Discussion and conclusion: This antimalarial plant is mildly cytotoxic with male antifertility properties. [ABSTRACT FROM AUTHOR]

Abstract

Background: Croton membranaceus (CM) is used for benign prostate hyperplasia treatment. Objective: Sub-chronic toxicity studies are non-existent and provided the basis for this study. Materials and Methods: 90 days oral administration of a low dose (LD) (30 mg/kg b. wt.), medium dose (MD) (150 mg/kg b. wt.), and high dose (HD) (300 mg/kg b. wt.) CM aqueous root extract to 3 groups (n=6 each) of male Sprague-Dawley rats, alongside a control group, was undertaken. Urinalysis, hepato-renal function tests, lipid profile, cardiac enzymes, and routine hematology tests were performed. Results: Triglyceride levels (C=1.05±0.19, LD=0.64±0.08, MD=0.55±0.04, HD=0.50±0.02 mmol/L) were significantly reduced (P<0.05). Very low density lipoprotein (C=0.48±0.09, LD=0.29±0.04, MD=0.25±0.02, HD=0.23±0.01 mmol/L) decreased significantly (P<0.05). Cardiac enzymes-creatinine kinase (C=568±172, LD=315±79, MD=441±209, HD=286±81 IU/L) decreased markedly (P<0.05) alongside lactate dehydrogenase (C=2675±875, LD=1667±1229, MD=1186±442, HD=855±239 IU/L) (P<0.05). Conclusion: C. membranaceus aqueous root extract is non-toxic but demonstrates anti-atherogenic and anti-ischemic potentials. [ABSTRACT FROM AUTHOR]

Abstract

Tuberculosis (TB) caused by Mycobacterium tuberculosisremains a serious public health challenge towards which new hits are urgently needed. Medicinal plants remains a major source of new ligands against global infectious illnesses. In our laboratories, we are currently investigating locally used ethnobotanicals for novel compounds against zoonotic tuberculosis. The microplate alamar blue assay (MABA) was used to study the anti-TB activity while the CellTiter 96® AQueousAssay, which is composed of solutions of a novel tetrazolium compound [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt; MTS] and an electron coupling reagent (phenazine methosulfate) PMS, was used for cytotoxic studies. Correlation coefficients (R2) were used to compare the relationship between antimycobacterial activity of the eight crude extracts against nonpathogenic strains and the pathogenic Mycobacterium bovis. Minimum inhibitory concentration (MICs) values indicated that all the eight tested medicinal plant species had activity against all the three tested mycobacterial strains. Minimum inhibitory concentration value as low as 19.5µg/mL was observed against non-pathogenic strains M. bovis. Activity of the crude extracts against M. aurumwas the best predictor of natural product activity against the pathogenic Mycobacterium bovis strain, with a correlation coefficient value (R2) of 0.1371. Results obtained from the current study validate, in part, the traditional utilization of the tested medicinal plants against tuberculosis. The unripe fruits from Solanum torvumare a potential source of safe and efficacious anti-TB crude drugs as well as a source for natural compounds that act as new anti-infection agents, and thus deserve further investigation towards development of a new class of molecules with activity against sensitive and drug resistant strains of M. bovis.

Abstract

Background. The current definitive treatment of Buruli ulcer with antibiotics makes the issue of antimicrobial drug resistance an unavoidable one. This is as a result of drug misuse by health personnel and patients’ noncompliance to treatment regimen. Monitoring of these factors and screening for new effective antimicrobials are crucial to effective management of Buruli ulcer disease. This study therefore investigated the inhibitory activity of some antibiotics against isolates of Mycobacterium ulcerans. Methods. Activity of eight antibiotics was tested against twelve M. ulcerans isolates (2 reference strains and 10 clinical isolates). The anti-M. ulcerans activities were determined by the agar dilution method and the minimum inhibitory concentrations (MICs) were determined by the agar proportion method. Results. All antimicrobials investigated had activity against M. ulcerans isolates tested. The MICs ranged from 0.16 μg/mL to 2.5 μg/mL. Azithromycin recorded the highest inhibitory activity at a mean MIC of 0.39 μg/mL, whilst clofazimine a second-line antileprosy drug, recorded the lowest at a mean MIC of 2.19 μg/mL. Among the four antituberculosis drugs, rifampicin had the highest activity with a mean MIC of 0.81 μg/mL. Conclusion. Azithromycin could be considered as a lucrative alternative to existing treatment methods for inhibiting M. ulcerans in Ghana.
