Shifting to Circular Manufacturing in the Global South: Challenges and Pathways

As the Global South shifts towards increased manufacturing, the negative effects on climate change and environmental pollution raise serious concerns. These global effects are increasingly felt locally, as reflected in health surveys throughout the Global South. The world cannot afford to wait for a natural development process to take place in which rising incomes might curb pollution. This article examines the challenges of reforming manufacturing in the Global South towards more sustainable practices. It also focuses on the lessons of the Sustainable Manufacturing and Environmental Pollution Program (SMEP) which has funded a series of environmental improvement projects across sub-Saharan Africa and South Asia aimed at reducing pollution in the manufacturing process. The lessons learned from these projects include the need to improve the tracking of the negative effects of the environmental damages caused by manufacturing and analyze the manufacturing supply chain processes to better identify potential points of intervention; as well as the need for more external financial and technical resources to expand these projects

Discovery and Biosynthesis of Gladiolin: A Burkholderia gladioli Antibiotic with Promising Activity against Mycobacterium tuberculosis.

An antimicrobial activity screen of Burkholderia gladioli BCC0238, a clinical isolate from a cystic fibrosis patient, led to the discovery of gladiolin, a novel macrolide antibiotic with potent activity against Mycobacterium tuberculosis H37Rv. Gladiolin is structurally related to etnangien, a highly unstable antibiotic from Sorangium cellulosum that is also active against Mycobacteria. Like etnangien, gladiolin was found to inhibit RNA polymerase, a validated drug target in M. tuberculosis. However, gladiolin lacks the highly labile hexaene moiety of etnangien and was thus found to possess significantly increased chemical stability. Moreover, gladiolin displayed low mammalian cytotoxicity and good activity against several M. tuberculosis clinical isolates, including four that are resistant to isoniazid and one that is resistant to both isoniazid and rifampicin. Overall, these data suggest that gladiolin may represent a useful starting point for the development of novel drugs to tackle multidrug-resistant tuberculosis. The B. gladioli BCC0238 genome was sequenced using Single Molecule Real Time (SMRT) technology. This resulted in four contiguous sequences: two large circular chromosomes and two smaller putative plasmids. Analysis of the chromosome sequences identified 49 putative specialized metabolite biosynthetic gene clusters. One such gene cluster, located on the smaller of the two chromosomes, encodes a trans-acyltransferase (trans-AT) polyketide synthase (PKS) multienzyme that was hypothesized to assemble gladiolin. Insertional inactivation of a gene in this cluster encoding one of the PKS subunits abrogated gladiolin production, confirming that the gene cluster is responsible for biosynthesis of the antibiotic. Comparison of the PKSs responsible for the assembly of gladiolin and etnangien showed that they possess a remarkably similar architecture, obfuscating the biosynthetic mechanisms responsible for most of the structural differences between the two metabolites

Institutional drivers for integrating palliative care services in a hospital in a sub-Saharan African military hospital context

Background: The growing burden of life-threatening illnesses and advancements in care interventions call for the intentional integration of palliative care services into existing care systems. The absence of active, functioning palliative care services in most hospitals in Ghana is a major concern. This study explored the factors influencing the integration of palliative care services in one of such institutions. Objectives: The aim of the study was to explore the institutional drivers of palliative care integration in a military health facility. Design: Exploratory qualitative study. Methods: We employed a qualitative exploratory study design situated within a constructivist paradigm. A purposive sampling method was used to select and interview 11 healthcare professionals. A semistructured interview was used to conduct face-to-face, in-depth interviews with participants between April and May 2022. A thematic data analysis was done based on the Braun and Clarke analysis process with the aid of QSR NVivo-12. Results: The six themes that describe the institutional driving factors for integrating palliative care services were cognitive restructuring, supportive logistics and infrastructure, staffing, healthcare professional skills, institutional policies and priorities, and utilization of focal persons. It was observed that a paradigm shift in the mindset of healthcare professionals and administrators was a major driver that would determine the integration of palliative care services. A cognitive restructuring will facilitate a more aggressive integration of palliative care services because logistics, staffing, and medication access will be prioritized. Conclusion: Institutions have the responsibility of aligning with the WHO policy on palliative care service access and must invest in training, staffing, prioritizing palliative care needs and policies, procurement of essential drugs, and the provision of logistics and supportive infrastructure to scale up the implementation of palliative care services

Work-related psychosocial challenges and coping strategies among nursing workforce during the COVID-19 pandemic: a scoping review

Abstract Background Nurses and midwives have been stretched by the COVID-19 pandemic amidst the heroic roles they have played during the peak of the COVID-19 pandemic. Nurses stood tall among their peers in the healthcare industry saving lives. The pandemic has had a toll on nurses physically, psychologically, and socio-economically. The numerous deaths have traumatized nurses coupled with the fear of possible infection. Nurses have seen their colleagues and loved ones lose their lives to the pandemic, nevertheless, they still render care to patients no matter the circumstances. Due to that, it is imperative to ascertain the extent to which nurses who are much needed in healthcare delivery have been affected by this pandemic. This scoping review used Arksey and O’Malley’s review methodology to investigate the nature of work-related psychosocial challenges nurses encountered during the peak of the pandemic, noting the major contributors to the challenges and the coping strategies used to address them. Methods We performed a scoping review and searched for articles from five databases including PUBMED, CINAHL, SCOPUS, Google Scholar, and Grey literature from December 2019 to December 2021. A total of 7,334 articles were retrieved for the study but 45 met the inclusion criteria. Results Work-related psychosocial challenges identified included stress, burnout (emotional exhaustion and depersonalization), Post-Traumatic Stress Disorder, depression, sleeplessness, and anxiety. Factors that accounted for the challenges were inadequate personal protective equipment (PPEs), discomfort using the PPEs, extreme workload, and fatigue. Nurses experienced job insecurity, business closure, and separation from family and loved ones, and these contributed to their challenges. Strategies used to deal with the challenges centred on emotion-focused and problem-focused coping. Conclusions The study recommends regular counselling and support for all nurses working at the frontline to help them better cope with the devastating effects of the pandemic so that they could build resilience towards future pandemics

Instruments used to assess quality of life of older adults in African countries:a scoping review

BACKGROUND: Over 60% of the population in sub-Saharan Africa, live in informal settlements (slums) with little or no resources. To be prepared to meet the needs of older people living in slums, it is necessary to know more about their quality of life (QoL). The objective of this review is to identify instruments, which can be used by researchers to assess the QoL of older adults living in African countries, especially those dwelling in slums. METHODS: A scoping review was performed using the databases Scopus, PubMed, and ISI Web of Science to retrieve studies published from January 2008 – September 2020. Studies were included if they reported generic QoL instruments, focused on adults with a mean age ≥ 50 and were conducted in African countries. RESULTS: In total, 18 studies were included using 7 unique instruments to measure QoL (EUROHIS-QOL-8, SWLS, WHOQOL-OLD, the WHOQOL-BREF, SF-36, SF-12 and RAND-38). All instruments could be interviewer-administered and had 5–36 items. However, little is known about their psychometric properties (validity and reliability), time-investment and cultural sensitivity of the domains included in the instruments. CONCLUSIONS: Even though this review retrieved instruments used to assess QoL of older adults in African countries, there is a need for further research on adjustment and validation of currently existing QoL instruments. In addition, the development and validation of a new instrument which can be used in (illiterate) older populations, living in slums in Africa should be considered
