Forested catchments surround most of the riverine systems in the Niger Delta area of Nigeria. Presently, there are no biomonitoring tools to assess the ecological health of forested rivers in the area. Hence, this study is aimed at developing a macroinvertebrate-based multimetric index for assessing the health forested riverine systems in the Niger Delta area of Nigeria. Physico-chemical variables and macroinvertebrates were sampled from 18 sites in 11 rivers. Physico-chemical variables were used to categorise river sites into three ecological classes, which include near natural sites (NNS), slightly disturbed sites (SDS) and moderately disturbed sites (MDS). Fifty-four(54) macroinvertebrate candidate metrics in four groups which include abundance, composition, richness and diversity were selected for the development of the Niger Delta forested rivers multimetric index (FoMIND). Of the 54 metrics selected, four were integrated into the FoMIND, and they include EPT/Chironomidae abundance, %ETOC, Diptera richness and evenness index. Correlation of integrated metrics with physico-chemical variables on redundancy analysis (RDA) ordination showed that EPT/Chironomidae abundance and evenness index positively associated with dissolved oxygen at NNS which confirmed the near-natural conditions of most of the forested riverine systems in the Niger Delta. Therefore, FoMIND is recommended as a rapid diagnostic tool for monitoring and assessing water quality conditions of rivers within forested catchments in Nigeria.

The increasing demand for sustainable alternatives to conventional antifungal agents has prompted extensive research into the antifungal properties of plant essential oils (EOs). This study investigates the use of EOs mixture (Origanum vulgare, Moringa oleifera, and Cinnamomum verum) for controlling fungal deterioration in wall paintings at the archaeological Youssef Kamal Palace in Nag Hammadi, Egypt. Fungal isolates were collected from deteriorated wall paintings and identified using phenotypic and genotypic analyses.

Bacterial biofilms pose significant challenges, from healthcare-associated infections to biofouling in industrial systems, resulting in significant health impacts and financial losses globally. Classic antimicrobial methods often fail to eradicate sessile microbial communities within biofilms, requiring innovative approaches. This review explores the structure, formation, and role of biofilms, highlighting the critical importance of exopolysaccharides in biofilm stability and resistance mechanisms.

Article Synopsis
- The study measured metal concentrations (Al, Cu, Ni, Cd, Cr, Pb) in seawater, sediments, and sea sponges across six Niger Delta sites and a cleaner reference site using advanced spectrometry techniques.
- The results indicated that sea sponges accumulated the highest levels of metals, especially aluminum, followed by sediment and seawater, with a specific order of concentration across the matrices.
- Additionally, a strong correlation was found between aluminum levels and DNA strand breaks in sponge cells, highlighting the potential of sea sponges as effective indicators of aquatic pollution and toxicity.
Assessment of the Prevalence and Patterns of Violence against Healthcare Workers in Nigeria: A Multicentre Study.

Article Synopsis
- In Nigeria, violence against healthcare workers (HCWs) is prevalent, significantly impacting healthcare access and workers' well-being, particularly in conflict and violent situations.
- A study surveyed 1,218 HCWs and found that 16.7% experienced physical violence, while 62.4% faced psychological violence, with common forms including verbal abuse and pushing.
- Major consequences included low job satisfaction, decreased confidence, and symptoms of post-traumatic stress disorder, primarily influenced by patient-related issues and hospital working conditions.

The spatio-temporal distribution, source apportionment, and risks of polycyclic aromatic hydrocarbon (PAHs) were investigated in the Sombreiro River Estuary, Niger Delta, Nigeria. Water, sediment and oysters were obtained from the estuary and analyzed for 16 priority PAHs using gas chromatograph coupled with mass selective detector after extraction. The levels of the ∑16-PAHs in the water, sediment and oyster ranged from 25-10079 µg/L, 495-12811 µg/kg and 489-10823 µg/kg respectively for all locations and seasons.
