The World Health Organization's 2015 report indicated that more than 35% of cases of ischaemic heart disease, the foremost cause of mortality and morbidity worldwide, and around 42% of strokes, the second most significant cause of global fatalities, might have been averted by minimizing or eliminating contact with chemical pollutants. Sub-Saharan Africa bears the brunt of heavy metal and cyanide pollution problems in developing nations, stemming from insufficient oversight of industrial activities and weak regulations. In 2020, a significant portion of Zimbabwe's occupational conditions and injuries, 25%, were attributable to activities within the mining industry. Subsequently, to lessen these concerns, this research seeks to build a health risk management framework for heavy metal and cyanide pollution within the industrial city of Kwekwe.
We will implement a convergent parallel mixed-methods study design in the research. Data, both qualitative and quantitative, will be acquired, analyzed, and synthesized in order to form a foundational basis for the risk framework. A cross-sectional analytical survey methodology will be used to assess the levels of heavy metals in surface water, soil, and vegetable samples. The analysis of free cyanide will be restricted to surface water samples. Employing a qualitative phenomenological approach, the research will delve into the experiences of participants regarding health events and risks potentially caused by heavy metals and cyanide exposure. To develop and validate a framework for managing identified health risks, the qualitative and quantitative results will be leveraged. The quantitative study's data analysis will leverage statistical analysis, whereas thematic analysis will be applied to the qualitative study's data. The University of Venda Ethics Committee (Registration Number FHS/22/PH/05/2306), along with the Medical Research Council of Zimbabwe (Approval Number MRCZ/A/2944), granted their approval to the study. The research project will scrupulously observe all ethical principles outlined in the Helsinki Declaration.
While existing frameworks for managing risk have played a substantial role in safeguarding human and environmental health, there's a compelling need to establish innovative and comprehensive frameworks to tackle the ever-changing threats presented by chemical contaminants. A well-structured management framework, if successfully implemented, could offer a means for controlling and preventing potentially toxic substances from occurring.
While existing risk management structures have proven effective in protecting human and environmental health, the emergence of novel, comprehensive frameworks is crucial for confronting the continuously evolving risks from chemical pollutants. A successfully formulated management framework could afford the opportunity to prevent and control potentially toxic substances.
The second-most common neurodegenerative disease encountered by medical practitioners is Parkinson's disease. The pathological hallmark is the substantial decrease in the number of dopaminergic neurons found within the substantia nigra (SN). Although the biochemical mechanisms exist, their operation is not presently comprehended. Many studies have conclusively shown that oxidative damage is the primary reason for Parkinson's Disease. Antioxidants, accordingly, might offer a practical approach to PD treatment. The thioredoxin (Trx) oxidation-reduction system, a potentially disease-related mechanism, is a valuable resource. A vital part of the Trx system, thioredoxin reductase 1 (TR1) is significant in its function.

Carbapenem-resistant Enterobacterales are a leading cause of concern within the spectrum of antimicrobial resistance (AMR) challenges. A concerning trend of resistance to polymyxins portends a potential for untreatable infectious diseases. Globally dispersed, these resilient organisms face inadequate surveillance, especially in nations lacking resources, as WHO reports underscore. This study's methodology includes comprehensive search techniques, data extraction, meta-analysis, and mapping, all aimed at elucidating the knowledge gaps surrounding carbapenem and polymyxin resistance risk factors in African countries.
Ten distinct Boolean searches, encompassing scientific and medical databases, as well as gray literature sources, were constructed and employed to definitively interrogate information up to the conclusion of 2019. After eliminating irrelevant results from the search, the remaining studies were assessed to determine the patterns of carbapenem and/or polymyxin susceptibility and/or resistance among E. coli and Klebsiella isolates recovered from human subjects. Data and study characteristics were extracted, coded, then analyzed and mapped geographically.
A thorough analysis resulted in 1341 reports highlighting carbapenem resistance in 40 of the 54 nations surveyed. E. coli resistance levels from 2010 to 2019, analyzed across nations, were determined as high (>5%) in three, moderate (1-5%) in eight, and low (<1%) in fourteen nations. These nations collectively provided at least 100 representative isolates. In another nine nations, the prevalence of resistance existed, but insufficient isolates prevented estimations of the extent. The carbapenem resistance patterns found among Klebsiella isolates differed considerably across ten nations, revealing high resistance as the dominant pattern in a certain number of locations, moderate resistance observed in others, and low resistance in some locations. In 11 nations, an incomplete analysis was carried out due to insufficient sample sizes. Despite a paucity of data pertaining to polymyxins, we identified 341 reports from 33 of the 54 countries, detailing resistance in a sample of 23. Ten nations saw variations in E. coli resistance, showcasing high levels in two, moderate in one, and low in six. Data on one nation was limited by the lack of sufficient isolates. In 8 countries, Klebsiella resistance was low, but in another 8 nations, insufficient isolates prevented a definitive resistance rate from being calculated.

In evaluating the complexities of antibiotic resistance, polymyxins, mcr-1, mgrB, and phoPQ/pmrAB should not be overlooked. The study across 23 nations demonstrated the presence of overlapping resistance to carbapenems and polymyxins.
While substantial data gaps exist, these data indicate substantial carbapenem resistance is widespread in Africa, and there is also a broad distribution of polymyxin resistance. This underscores the importance of supporting robust AMR surveillance, antimicrobial stewardship, and infection control, encompassing the crucial elements of animal and environmental health.
Although substantial data lacunae persist, these data demonstrate that substantial carbapenem resistance is prevalent throughout Africa, and polymyxin resistance is also extensively disseminated, necessitating the reinforcement of robust antimicrobial resistance surveillance, antimicrobial stewardship, and infection control programs, while simultaneously addressing broader aspects of animal and environmental health.
