ABSTRACT

East Africa (Musa spp.), notably Musa acuminata, "Matooke" a staple and economically important food in the region. Here, 12 selected M. acuminata peels extract (MAPE) bioactive compounds were studied for hepatoprotective potentials in aluminium chloride-induced hepatoxicity in adult BALB/c mice. GC-MS analysis was used to identify active components of MAPE. In silico estimation of the pharmacokinetic, the GCMS-identified compounds' toxicity profile and molecular docking were compared with the standard (Simvastatin) drug. Hepatotoxicity was induced using aluminium-chloride treated with MAPE, followed by biochemical and histopathological examination. Twelve bioactive compounds 2,2-Dichloroacetophenone (72870), Cyclooctasiloxane 18993663), 7-Hydroxy-6,9a-dimethyl-3-methylene-decahydro-azuleno[4,5-b]furan-2,9-dione (534579), all-trans-alpha-Carotene (4369188), Cyclononasiloxane (53438479), 3-Chloro-5-(4-methoxyphenyl)-6,7a-dimethyl-5,6,7,7a-tetrahydro-4H-furo[2,3-c]pyridin-2-one (536708), Pivalic acid (6417), 10,13-Octadecadienoic acid (54284936), Ethyl Linoleate (5282184), Oleic acid (5363269), Tirucallol (101257), Obtusifoliol (65252) were identified by GC-MS. Of these, seven were successfully docked with the target proteins. The compounds possess drug likeness potentials that do not inhibits CYP450 isoforms biotransformation. All the docked compounds were chemoprotective to AMES toxicity, hERGI, hERGII and hepatotoxicity. The animal model reveals MAPE protective effect on liver marker's function while the histological studies show regeneration of the disoriented layers of bile ducts and ameliorate the cellular/histoarchitecture of the hepatic cells induced by AlCl3. The findings indicate that MAPE improved liver functions and ameliorated the hepatic cells' cellular or histoarchitecture induced by AlCl3. Further studies are necessary to elucidate the mechanism action and toxicological evaluation of MAPE's chronic or intermittent use to ascertain its safety in whole organism systems.

ABSTRACT

PAHs are pervasive pollutants known to bioaccumulate in environmental matrices, plants, and humans. Dr. Iguedo Goko Cleanser® is a polyherbal drug with unsubstantiated claims to treat various diseases in sub-Saharan Africa. PAHs were measured following EPA-16 PAHs guidelines using Gas Chromatography (Agilent-6890N, USA). The drug's exposure-associated public health concerns was determined using suitable mathematical paradigms. PAHs present were acenaphthene (2.74 × 10-2), pyrene (2.7598 × 10-2), and chrysene (5.1277 × 10-2) ppm. Dietary intake of chrysene, acenaphthene and pyrene for adults, and children ranged from 2.466-4.615 × 10-3 and 1.215-2.308 × 10-3 ppm/mg/kg, respectively. B[α]Peq, EDB[α]Peq, and incremental lifetime cancer risk were determined to be 5.6777 × 10-4, 5.109912 × 10-5 and 5.3289 × 10-12, respectively. Our results suggest a high risk of non-carcinogenic adverse health effects, especially on chronic exposure among adolescents and adults, necessitating caution and/or avoidance of its chronic use. Therefore, policy formulation and implementation as regards the safety of plant-based remedies and allied products before their distribution among end-users must be ensured.

ABSTRACT

Advances in industrial and technological innovations have led to significant socio-economic benefits, but with overwhelming negative impacts on the environment. These impacts include the infiltration of organic contaminants into soil, water, and air, posing a threat to the environment and public health. Polybrominated diphenyl ethers (PBDEs), heavy metals, and polycyclic aromatic hydrocarbons (PAHs) are increasingly released as waste, endangering the environment. In countries like Ghana, where regulations are weakly enforced, industrial waste is released uncontrollably, posing threats to public health, environmental integrity, and food systems. This study systematically evaluated existing literature on PBDEs, heavy metals, PAHs, and organic contaminant exposure in Ghana and proposes a roadmap for achieving food safety and protecting the environment and human health. The research identified high mobility of specific heavy metals and risks associated with PBDEs and PAHs in sediments, dumpsites, and various food items. Unregulated dumping of electronic waste with PBDEs raised environmental concerns. An integrated approach is needed to address the multifaceted impact of organic pollutants on public health and ecosystems. Urgent implementation of effective environmental management strategies and regulatory measures is crucial. The study proposed short- to mid-term priorities emphasising the need to foster collaboration and implementing global measures. The mid- to long-term strategy includes a national information surveillance system, local monitoring capacity development, and integrating land contamination controls with food safety legislation. These measures would mitigate risks, ensure sustainable practices, and improve overall food safety management in Ghana, serving as a model for regions facing similar challenges with diverse pollutants.

ABSTRACT

The Niger Delta environment is under serious threat due to heavy metal pollution. Many studies have been conducted on the heavy metal contamination in soils, water, seafood and plants in the Niger Delta ecosystem. However, there is a lack of clear understanding of the health consequences for people and strategies for attaining One Health, and a dispersion of information that is accessible. The study focused on investigating the contamination levels, distributions, risks, sources and impacts of heavy metals in selected regions of the Niger Delta. Prior studies revealed that the levels of certain heavy metals, including Cd, Pb, Cu, Cr, Mn, Fe and Ni, in water, sediment, fish and plants in most Niger Delta ecosystems were higher than the acceptable threshold attributed to various anthropogenic stressors. In the reviewed Niger Delta states, ecosystems in Rivers state showed the highest concentrations of heavy metals in most sampled sites. Groundwater quality was recorded at concentrations higher than 0.3 mg/L World Health Organization drinking water guideline. High concentrations of copper (147.915 mg/L) and zinc (10.878 mg/L) were found in Rivers State. The heavy metals concentrations were greater in bottom-dwelling organisms such as bivalves, gastropods and shrimp than in other fishery species. Heavy metal exposure in the region poses risks of communicable and non-communicable diseases. Diverse remediation methods are crucial to reduce contamination levels, but comprehensive strategies and international cooperation are essential to address the health hazards. Actively reducing heavy metals in the environment can achieve One Health objectives and mitigate disease and economic burdens.

ABSTRACT

In Nigeria, environmental pollution linked with PAHs has been increasing, and PAHs in fish pose a threat to all, especially those that rely upon fish. This systematic review aimed at evaluating human health effect of PAHs concentration in dried and fresh fish in Nigeria. A systematic literature search was carried out on PubMed, MedLine, Web of Science and Science Direct, etc. From the total of 31 articles reviewed, 19 studies reported on fresh fish and 9 on dried fish. 54.8% of the selected research reported on high-level PAH accumulation in fresh fish. PAH contamination was mainly from petrogenic and pyrogenic sources. The major health outcomes from this study were cancer and non-carcinogenic risks, skin irritations, gastrointestinal, child deformities, respiratory disorders, emotional distresses, neurological and haematological effects. It is recommended that regulations be made to abate and monitor the environmental exposure of humans to PAHs to ameliorate the public health effects.

ABSTRACT

The crude oil-rich Niger Delta region of Nigeria is under threat due to anthropogenic activities that include mainly PAH contamination. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), multiple online searches were conducted using several databases (e.g. Cochrane Library, Scopus, Embase, National Library of Medicine, PubMed etc.) between October and November 2022 to collect evidence on pervasiveness, bioaccumulation and health challenges posed by PAH in Nigeria Niger Delta. Included studies were appraised for quality using the Standard for Quality Improvement Reporting Excellence (SQUIRE 2.0) framework and the Joanna Briggs (JB) checklist and retrieved data were analysed using the narrative synthesis method. With the indiscriminate exposure of the local inhabitants to PAH and a lack of public health policies that efficiently prevent exposure-associated adverse health events, there is a need for a collaborative and multi-disciplinary approach, cutting across boundaries of animal, human, and environmental health to undertake risk assessments, develop plans for response and control in an attempt to protect public health. The complex and wide distribution of PAHs within the Niger Delta region would benefit of the One Health strategy. Such systemic approach would help managing the harmful effects of PAHs on ecosystems, from environmental remedial approaches to measures to mitigate exposure-associated risks. One health, including environmental health and food safety, would help risk assessors and risk managers in prioritising actions for the prevention and mitigation of PAHs pollution and its spread and accumulation.

ABSTRACT

OBJECTIVE: To investigate the perceptions of parents towards universal new-born screening for hearing loss in Nigeria. METHODS: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system. A comprehensive search was undertaken using multiple databases (National Library of Medicine, PubMed, Cochrane Library, Scopus, Google Scholar, and MEDLINE) published in English between 2009 and 2018. The sample size of 10 studies were retrieved by using a predefined inclusion and exclusion criteria, keywords, and Boolean operator search patterns. Data extraction and analysis and quality appraisal of the selected articles was carried out. RESULTS: 80% of the identified studies indicated negative perceptions of Nigerian parents towards new-born hearing loss screening programmes. Possible reasons behind such negative perceptions were categorised into demographic factors, psychological factors, behavioural factors, and service-related factors. Specifically, barriers included low income, misconceptions, mode of delivery, fear of associated risk with screening procedure, preference for traditional medicines, inappropriately designed screening programmes, cost of screening programmes, resource-limited settings, lack of awareness about risk factors and their effects. CONCLUSION: The research concluded that it is necessary to focus on the range of underlying factors (including awareness and education) contributing in shaping the above mentioned negative perceptions among Nigerian parents. The findings have great implications for the theoretical researchers for developing future research path as well as practical suggestion for authorities in policymaking in the healthcare sector in Nigeria.
