Abstract

Patients with schizophrenia (SZ) often experience difficulties and impairment in daily functioning. Various factors influence functional outcomes, such as the duration of illness (DOI), the intensity of symptoms, and cognitive impairments. This study aimed at assessing the total, direct, and indirect contribution of the DOI to three key areas of daily functioning for individuals with stable SZ: life skills, work abilities, and interpersonal relationships.Spearman's partial correlations, adjusted for age, gender, and education, were computed between the DOI, symptoms and cognitive variables, and the three real-life functioning domains. We performed three generalized linear mediation models, one for each selected domain of functioning as the dependent variable. Symptoms and cognitive variables significantly correlated with the DOI and at least one of the functioning domains were included in the mediation models as possible mediators between the DOI and the domain of real-life functioning with which they were correlated. The DOI was the independent variable in all models. Effects were computed in total, direct, indirect, and component-estimated forms. A p-value of

Abstract

Dietary live insect larvae were recently proposed for use in laying hens and broiler−intensive chicken farming as an innovative form of environmental enrichment, but their use in native dual-purpose chickens has never been investigated. This study aims to evaluate the effects of live black soldier fly (BSF) larvae as environmental enrichment in two autochthonous dual-purpose chicken breeds, namely Bionda Piemontese (BP) and Bianca di Saluzzo (BS), in terms of bird performance, behaviour, integument status, excreta corticosterone metabolites (ECMs), and microbiota analyses. A total of 90 BP and 90 BS hens aged 308 days old were randomly distributed between two treatment groups (three replicates/group/breed, 15 hens/replicate). For the following 90 days, the control group (C) was fed a commercial feed only, whereas the BSF group was fed the commercial diet plus BSF live larvae calculated at 6% of the expected daily feed intake (DFI). Larva ingestion time, bird performance, integument scores, and behavioural observations were assessed at regular intervals, and excreta samples were collected to evaluate ECM and microbiota. The larva ingestion time became faster over the course of the experimental trial (P

Abstract

This research intends to recycle bone and incorporate it into concrete for radiation shielding application using Phy-X/PSD software. Cement, sand and granite were mixed in proportion of 0.5 kg:1 kg:1 kg to obtain sample A. Other concretes composing of cement, sand, granite and bone ash was in proportion 0.45 kg:1 kg:1 kg:0.05 kg, 0.1 kg:1 kg:1 kg:0.4 kg and 0.35 kg:1 kg:1 kg:0.15 kg to obtain samples B, C and D respectively. 0.5 water-to-cement (W/C) ratio was adopted throughout the mixes because the control mix contain the normal water quantity for normal hydration of cement. Replacing the bone ash for the cement in the fabricated concretes enhances their densities where the fabricated concretes' density decreased from 2.33 g/cm3 to 2.22 g/cm3 by raising the reinforcing bones fly ash concentration from 0 to 0.15 kg. Additionally, increasing the bones fly ash concentration within the fabricated concretes increases their linear attenuation coefficient (LAC) where the fabricated concretes’ μ values at 0.662 MeV reach 0.181 cm−1, 0.178 cm−1, 0.174 cm−1, and 0.171 cm−1,respectively for concretes A, B, C, and D. The use of other local materials is recommended, as it improves waste management being the major aim of the sustainable development goal.

Abstract

Brewery by-products are recognised as suitable rearing substrates for Hermetia illucens, better known as black soldier fly (BSF) but information about the impact of different ratios of brewer’s spent grains (BSG) and brewer’s spent yeast (BSY) are still scarce. This study evaluated the effects of BSG-BSY-based diets on BSF larval growth, survival, bioconversion efficiency, nutritional profile, and microbiota and mycobiota. A total of 3 000 6-day-old BSF larvae were allotted to five dietary treatments (six replicate boxes/diet, 100 larvae/box): (i) BSY2.5 (25 g/kg of BSY+975 g/kg of BSG), (ii) BSY5 (50 g/kg of BSY+950 g/kg of BSG), (iii) BSY7.5 (75 g/kg of BSY+925 g/kg of BSG), (iv) BSY10 (100 g/kg of BSY+900 g/kg of BSG), and (v) control (Gainesville diet). Larval weight and substrate pH were recorded every 4 days. At the end of the trial (5% of prepupae), bioconversion efficiency corrected for residue (BER), reduction rate (RR), and waste reduction index (WRI) were calculated, and the larval proximate composition, microbiota and mycobiota characterised. At 10 and 14 days of age, BSY7.5 and BSY10 larvae displayed higher weight than BSY2.5 and BSY5 (P 0.05). The BSY10 larvae displayed lower ether extract content than the other BSG-BSY-based diets (P > 0.001). The use of BSG-BSY-based diets did not influence the alpha diversity of larval microbiota and mycobiota (P > 0.05), but a specific microbial signature was identified per each dietary treatment (Porphyromonadaceae [BSY5], Sphingomonas [BSY7.5], Bacillus [BSY10] and Ruminococcus and Myroides [BSG-BSY-based diets]; P

Abstract

Silkworms have been farmed for their silk since ancient times. After silk reeling, their chrysalides are consumed as food in several Asian countries. Despite the long rearing tradition of this insect, few studies have investigated the silkworm’s microbiological safety all along the life cycle, focusing on detecting silkworm pathogens or on the safety of the dried chrysalis for food consumption. However, the in-farm rearing process, which takes around forty days, may affect the microbial load of the silkworm and of the rearing environment, as well as the quality of fresh cocoon and other performance parameters. No data is available on how microbial contamination changes during the rearing period and between different farmers. Furthermore, in light of the possible use of the chrysalis as food, it is crucial to understand how its microbial load varies according to the water content. To address these specific questions, we conducted an investigation involving the analysis of specific microbial indicators commonly used in the food chain. We collected environmental and silkworm samples from several farms. The examination covered the entire life cycle of silkworms, beginning with the first instar larvae and concluding with the scrutiny of both freshly harvested and dried pupae. Silkworm farms in Northeast Italy proved to be an appropriate model system for carrying out the experimentation. Additionally, an evaluation of rearing performance was conducted, with a focus on the quality of fresh cocoons and the survival rate of the insects.

Abstract

Rearing scale may influence black soldier fly (BSF) larvae traits when they are fed on a single diet, but different feeding substrates have not been tested yet. This study evaluated the effects of wheat starch processing by-products-based diets on growth performance, bioconversion efficiency, and nutritional profile of BSF larvae reared in different scales. Four diets (D1 and D2 [isonitrogenous, isolipidic and isoenergetic]; D3 and D4 [displaying 1:1 and 1:2 as protein to carbohydrate ratios, respectively]) were tested at 3 rearing scales (4 replicate boxes/diet, with a constant volume [0.84 cm3]/larva and feed [0.7 g]/larva): 1) small (S; 12 × 12 cm, substrate height: 4 cm, 686 6-day-old larvae (6-DOL)/box), 2) medium (M, 32 × 21 cm, substrate height: 7 cm, 5 600 6-DOL/box), and 3) large (L, 60 × 40 cm, substrate height: 7 cm, 20 000 6-DOL/box). Larval weight was recorded at the beginning of trial and every 4 days, and growth rate (GR), specific growth rate (SGR), feed conversion ratio (FCR), survival, bioconversion efficiency corrected for residue (BER), reduction rate (RR), and waste reduction index (WRI) calculated at the end of larval growth (frass DM ≥ 55%). Substrate pH, T and height were measured at the beginning, every 4 days, and end of trial. Larval proximate composition was analysed at the end of trial. Data were analysed by generalised linear mixed model (SPSS software, P

Abstract

Arcanobacterium haemolyticum is an extremely rare cause of cerebral abscess. We present a unique case of Arcanobacterium haemolyticum sinusitis complicated by preseptal cellulitis and cerebral abscess. The patient initially presented with pharyngitis and then developed sinus congestion, headache and facial pain. Computed tomography and magnetic resonance imaging revealed a right gyrus rectus cerebral abscess and paranasal sinus infection. The patient underwent endoscopic sinus surgery and cultures revealed Arcanobacterium haemolyticum. Repeat imaging revealed maturation and progression of intracranial abscess. The abscess was drained and patient was treated with parenteral and oral antibiotics until complete clinical and radiological remission. This case highlights the importance of recognizing Arcanobacterium haemolyticum as a cause of invasive disease in immunocompetent hosts.

Abstract

The Sonic Hedgehog (Hh) signal transduction pathway plays a critical role in many developmental processes and, when deregulated, may contribute to several cancers, including basal cell carcinoma, medulloblastoma, colorectal, prostate, and pancreatic cancer. In recent years, several Hh inhibitors have been developed, mainly acting on the Smo receptor. However, drug resistance due to Smo mutations or non-canonical Hh pathway activation highlights the need to identify further mechanisms of Hh pathway modulation. Among these, deacetylation of the Hh transcription factor Gli1 by the histone deacetylase HDAC1 increases Hh activity. On the other end, the KCASH family of oncosuppressors binds HDAC1, leading to its ubiquitination and subsequent proteasomal degradation, leaving Gli1 acetylated and not active.It was recently demonstrated that the potassium channel containing protein KCTD15 is able to interact with KCASH2 protein and stabilize it, enhancing its effect on HDAC1 and Hh pathway.KCTD15 and KCTD1 proteins share a high homology and are clustered in a specific KCTD subfamily. We characterize here KCTD1 role on the Hh pathway. Therefore, we demonstrated KCTD1 interaction with KCASH1 and KCASH2 proteins, and its role in their stabilization by reducing their ubiquitination and proteasome-mediated degradation. Consequently, KCTD1 expression reduces HDAC1 protein levels and Hh/Gli1 activity, inhibiting Hh dependent cell proliferation in Hh tumour cells. Furthermore, analysis of expression data on publicly available databases indicates that KCTD1 expression is reduced in Hh dependent MB samples, compared to normal cerebella, suggesting that KCTD1 may represent a new putative target for therapeutic approaches against Hh-dependent tumour.

Abstract

Summary Objectives Individuals with perinatally acquired HIV infection have benefited from antiretroviral therapy. However, they often have complex patterns of major resistance mutations that limit the effectiveness of available antiretroviral medications. Knowledge of incidence rates of major antiretroviral resistance mutations should provide a benchmark enabling comparisons of different HIV care delivery modalities. Methods We test the hypothesis that incidence rate of major antiretroviral resistance mutations will decline with improvement in HIV care between 1998 and 2009 to NRTI, NNRTI, PI and triple class resistance in perinatally HIV infected individuals. Logistic regression is used to evaluate predictors of single and triple class resistance. Results Sixty-six individuals are included from a total population of 97 perinatally HIV infected individuals. The incidence rate of NRTI, NNRTI, PI and triple class resistance decreases with decreasing age in parallel with the introduction of new HIV treatment regimens. The youngest children (born 2000–2007) are free of triple class resistance. Mono-therapy associates with major resistance mutations to NRTI (OR 8.7, CI 1.5–50.9, P 0.02); NNRTI exposure associates with major resistance mutations to NNRTI (OR 24.4, CI 5.7–104.5, P 0.01) and triple class resistance (OR 10.7, CI 1.8–67.1, P 0.01). Cumulative viral load is an important predictor of PI resistance (OR 4.0, CI 1.3–12.3, P 0.02). Conclusions There is a progressive decrease in the incidence rate of major resistance mutations to antiretroviral drugs and triple class resistance from the oldest to the youngest birth cohort; where adolescents have the highest risk of harboring resistant viruses. The incidence rate of major antiretroviral resistance mutations provides a benchmark for the comparative measurement of effectiveness of different HIV care delivery modalities.

Abstract

The search for new, alternative and sustainable feeding sources, including insects, has become an important challenge on the feed market. In 2017, the European Union (EU) started to allow the use of insect meals as feeds for fish. In addition, in 2021, the EU also authorised the use of insect meal for pig and poultry farming. However, the adoption of insect meal by the European aquaculture sector is still limited, and this is mostly due to the lack of availability of insects and their higher costs than conventional feed ingredients. Thus, the insect-based feed industry is still in its infancy, and its successful development and integration in the food value chain depend on several factors. Among these, the technical feasibility and production of quality products, and acceptance by European consumers and farmers are relevant factors. To address these points, this narrative review describes the state of the art of the potential role of insect-based feeds. The stakeholders’ and consumers’ perspectives are investigated, along with the effects of insect-based feeds on the production and nutritional values of fish, poultry (meat and eggs), and pork. Indeed, matching the nutritional values of insect products with conventional feeds is one of the future challenges of the insect sector, as their nutritional composition is highly dependent on the rearing substrates, and thus, their use in animal feeding needs to be investigated carefully. Feeding animals with insect-based diets affects their growth performances and the chemical composition of the derived products (fish fillets, meat, and eggs). Whether these effects can be considered positive or negative seems to depend to a great extent on the percentage of insects included in their diets and the chemical composition of the ingredients. The use of insect-based feeds has also shown a potential to improve the nutritional features and values of animal products and even to add new ones. Finally, many of the acceptance studies on the use of insects in feeds have focused mostly on the consumers’ perception rather than on industry stakeholders (e.g., farmers). Future research should focus more on the farmers’ perceptions on and market analyses of these innovative feeds. Even though it is likely that the upscaling of the insect sector will lead to a decrease in prices and an increase in market availability, it is still critical to understand the potential barriers and drivers for the implementation of insects as feeds from a production point of view.

Abstract

OVSICORI In this work, we investigate the compositions and origin of metasomatic fluids responsible for the formation of sulfide replacement textures in Mg-Suite lithologies of lunar samples 67915-149 and 67915-150. We have constructed a quantitative thermodynamic model of the composition of the metasomatic fluid using fO2, fS2, and temperature constraints derived from a thermodynamic analysis of the metasomatic fluid-mineral reactions and the measured compositions of the phases in the sulfide assemblages. Results from this modeling indicate that the metasomatic fluid responsible for the formation of the sulfide replacement textures was likely dominated by a combination of H2 and CH4, with minor abundances of H2O, CO, and H2S. The modeling indicates that H2S was, by orders of magnitude, the dominant S-species present in the metasomatic fluid and S isotopes in the replacement sulfides suggest that the fluid experienced significant removal of H2S by sulfide precipitation. The calculated H2 and H2O contents of the metasomatic fluid are consistent with those that might be expected for the late stage degassing of shallowly emplaced, intrusive magma bodies. En este trabajo, investigamos las composiciones y el origen de los fluidos metasomáticos responsables de la formación de texturas de reemplazo de sulfuro en litologías de Mg-Suite de muestras lunares 67915-149 y 67915-150. Hemos construido un modelo termodinámico cuantitativo de la composición del fluido metasomático utilizando fO2, fS2 y restricciones de temperatura derivadas de un análisis termodinámico de las reacciones metasomáticas fluido-mineral y las composiciones medidas de las fases en los ensamblajes de sulfuro. Los resultados de este modelo indican que el fluido metasomático responsable de la formación de las texturas de reemplazo de sulfuro probablemente estuvo dominado por una combinación de H2 y CH4, con abundancias menores de H2O, CO y H2S. El modelo indica que el H2S era, por órdenes de magnitud, la especie S dominante presente en el fluido metasomático y los isótopos S en los sulfuros de reemplazo sugieren que el fluido experimentó una eliminación significativa de H2S por precipitación de sulfuro. Los contenidos calculados de H2 y H2O del fluido metasomático son consistentes con los que podrían esperarse para la última etapa de desgasificación de cuerpos de magma intrusivos poco emplazados.

Abstract

In recent years, there has been an increasing interest in electrically conductive hydrogels for a wide range of biomedical applications, like tissue engineering or biosensors. In this study, we present a cost-effective conductive hydrogel based on alginate and graphene nanoplatelets for extrusion-based bioprinters. The hydrogel is prepared under ambient conditions avoiding high temperatures detrimental for cell culture environments. Investigation of the hydrogel revealed a conductivity of up to 7.5 S/cm, depending on the ratio of platelets. Furthermore, in vitro tests with human embyronic kidney cells - as an example cell type - showed good adhesion of the cells to the surface of the conductive hydrogel. Electrochemical measurements revealed a low electrode impedance which is desirable for the extracellular recording, but also low electrode capacitance, which is unfavorable for electrical stimulation purposes. Therefore, future experiments with the graphene nanoplatelets-based hydrogels will focus on electrodes for biosensors and extracellular recordings of neurons or cardiac myocytes.

Abstract

This chapter seeks to place carbon capture and storage (CCS) in a legal framework. The chapter commences with an overview of relevant international law. The coverage of institutional frameworks continues with a discussion and analysis of the key provisions of European Directive 2009/31/EC on the geological storage of CO2. The chapter then explores some key issues relating to potential liabilities for CCS related activities, in particular examining the difficult question of allocating long-term, post-closure liabilities. The chapter concludes with an analysis of some of the key future challenges for regulatory systems and for CCS more generally.

Abstract

Our cognitive map is the internal mental representation of the world that individuals develop through both direct and indirect experience and other modes of learning. It contains knowledge of the spatial structure of places and the world, as well as the beliefs, meaning, opinion, and recollections associated with what is known. Our cognitive map supports decision making and understanding of small spaces such as desktops, offices, and cabinets, and also much larger spaces that together establish all that we know of the world.

Abstract

The use of acoustics to measure near-bed sediment transport processes has gained increasing acceptance within the sedimentological community over the past two decades. The idea of using sound to study fundamental sediment processes in the underwater environment is attractive, and, in concept, straightforward. A pulse of high-frequency sound is transmitted downward from a directional sound source usually mounted a meter or two above the bed. As the pulse propagates down toward the bed, sediment in suspension backscatters a proportion of the sound and the bed generally returns a strong echo. The signal backscattered from the suspended sediments can be used to obtain vertical profiles of the suspended concentration and particle size and profiles of the three orthogonal components of flow. The strong echo from the bed can be used to measure the bed forms. Further, the profiles can be obtained with sufficient spatial and temporal resolution to allow near-bed turbulence and intrawave sediment processes to be probed; this coupled with the bedform morphology observations provides sedimentologists and coastal engineers with an extremely powerful tool to advance understanding of sediment entrainment and transport. All of this is delivered with almost no influence on the processes being observed, because sound is the instrument of measurement.

Abstract

Publisher Summary This chapter explores whether seagrass populations have the characteristics that make a metapopulation approach a useful one for investigation. Measures for the protection of seagrass populations must consider local and metapopulation dynamics, given that local recruitment was often influenced by the regional abundance of seagrasses and dispersal patterns. It is highly probable that the possibility of metapopulation structure operating in seagrass will, in fact, vary among species and even within species from different locations, given the wide variety of biological and ecological characteristics outlined in the chapter. As the next step, it will be necessary for seagrass studies to adopt a regional or landscape perspective of patch colonization, extinction, and dispersal, setting the stage for more detailed assessment of metapopulation biology and a more detailed understanding of the persistence of seagrass populations on the local scale. Collection of more detailed demographic information on seagrasses and improved descriptions of seagrass spatial structure are required to evaluate better whether a regional view of the local persistence of seagrasses is appropriate and informative.

Abstract

Objective: To use Multi-Criteria Decision Analysis (MCDA) to determine weights for eleven criteria in order to prioritize COVID-19 non-critical patients for admission to hospital in healthcare settings with limited resources. Methods: The MCDA was applied in two main steps: specification of criteria for prioritizing COVID-19 patients (and levels within each criterion); and determination of weights for the criteria based on experts’ knowledge and experience in managing COVID-19 patients, via an online survey. Criteria were selected based on available COVID-19 evidence with a focus on low- and middle-income countries (LMICs). Results: The most important criteria (mean weights, summing to 100%) are: PaO2 (16.3%); peripheral O2 saturation (15.9%); chest X-ray (14.1%); Modified Early Warning Score-MEWS (11.4%); respiratory rate (9.5%); comorbidities (6.5%); living with vulnerable people (6.4%); body mass index (5.6%); duration of symptoms before hospital evaluation (5.4%); CRP (5.1%); and age (3.8%). Conclusions: At the beginning of a new pandemic, when evidence for disease predictors is limited or unavailable and effective national contingency plans are difficult to establish, the MCDA prioritization model could play a pivotal role in improving the response of health systems.

Abstract

This chapter explains a direct-write approach for fabricating highly integrated, multilayer components using a Micropen to deposit slurries in precise patterns. Micropen deposition enables printing of multilayer material structures on nonplanar substrates, enabling high-density circuitry with integrated passive components. Furthermore, this chapter presents the technologies instrumental to material integration by the Micropen, including equipment operation, slurry preparation, deposition constraints, and cofiring of multimaterial integrated passives. The four example device elements include: high precision resistors, high-capacitance density dielectrics, integrated inductor coils, and chemical sensors. The direct-write approach provides the ability to fabricate multifunctional, multimaterial integrated ceramic components (MMICCs) in an agile way with rapid turnaround. This technique is used to fabricate devices such as integrated RC filters, multilayer voltage transformers, and other passive components. Thus with advent of new levels of pen tip sophistication, vision control systems, agile materials delivery, and ultralow temperature materials, pen-dispense direct write appears to be most promising route towards high-speed, multimaterial electronics fabrication.

Abstract

A trust-region algorithm is presented for finding approximate minimizers of smooth unconstrained functions whose values and derivatives are subject to random noise. It is shown that, under suitable probabilistic assumptions, the new method finds (in expectation) an ϵ-approximate minimizer of arbitrary order q≥1 in at most O(ϵ−(q+1)) inexact evaluations of the function and its derivatives, providing the first such result for general optimality orders. The impact of intrinsic noise limiting the validity of the assumptions is also discussed and it is shown that difficulties are unlikely to occur in the first-order version of the algorithm for sufficiently large gradients. Conversely, should these assumptions fail for specific realizations, then “degraded” optimality guarantees are shown to hold when failure occurs. These conclusions are then discussed and illustrated in the context of subsampling methods for finite-sum optimization.

Abstract

ABSTRACT: The aim of the study was to evaluate the effects of partially defatted black soldier fly (Hermetia illucens, HI) larva meal on the carcass characteristics and meat quality of Muscovy ducks (Cairina moschata domestica). A total of 192 female ducks aged 3 d were divided between 4 dietary treatments (6 pens/treatment; 8 birds/pen), characterized by increasing levels of substitution of corn gluten meal with HI meal (0%, 3%, 6%, and 9%; HI0, HI3, HI6, and HI9, respectively), and reared until 50 days of age. Twelve birds/treatment (2 birds/pen) were slaughtered on d 51 to evaluate the slaughter traits (i.e., carcass, breast, thigh, and organs weights), carcass yield and meat quality. The slaughter weight, hot and chilled carcass weights, and abdominal fat weight showed a quadratic response to HI meal (minimum for the HI6 group, P < 0.05). Dietary HI meal inclusion did not influence the ultimate pH, the color, the proximate composition or the thiobarbituric acid reactive substances (TBARS) values in either the breast or thigh meat. The mineral profile of the meat was slightly affected by the dietary treatment, with a linear increase in the Cu content of the thigh meat (P < 0.05), whereas no differences were observed for Zn, Mn, or Fe. Dietary HI meal inclusion increased the saturated fatty acid rate in the thigh meat (maximum for the HI9 group, P < 0.05), and the monounsaturated and polyunsaturated fatty acid content in the breast meat (maximum for the HI0 and HI9 groups, respectively, P < 0.05). The ∑n-6/∑n-3 ratio decreased linearly in both the breast and thigh meat, with the HI9 group showing the lowest values (P < 0.05). Finally, the heavy metal concentrations were below the EU limits for poultry meat. To conclude, the inclusion up to 9% of partially defatted HI larva meal in the diet of Muscovy ducks did not affect the slaughter traits or the meat quality, although it did affect the meat fatty acid profile.

Abstract

An anaerobic facultative Gram-stain positive bacterium was isolated from human gut microbiota. Strain Marseille-P5551T was considered to be a new genus within the phylum Firmicutes, as it exhibits a 91.87% similarity level with Faecalicatena orotica (NR_117129.1), the phylogenetically closest related species. The draft genome size of strain Marseille-P5551T is 4 142 938 bp with 44.4% of G + C content. We hereby suggest the creation of Luxibacter massiliensis gen. nov., sp. nov., as a new bacterial genus.

Abstract

Anaerococcus marasmi sp. nov. strain Marseille-P3557T is a new species isolated from a stool of a Nigerian child with marasmus. The genome of Marseille-P3557T was 2 130 060 bp long (35.4% G + C content). The closest species based on 16S ribosomal RNA sequence was Anaerococcus prevotii strain 20548, with 97.6% sequence similarity. Considering phenotypic features and comparative genome studies, we propose the strain Marseille-P3557T as the type strain of Anaerococcus marasmi sp. nov., a new species within the genus Anaerococcus.

Abstract

Fungal endocarditis/aortitis is an uncommon yet emerging entity accounting for 2% to 4% of all cases of infective endocarditis and continues to be associated with a poor prognosis. We present the first case of polyethylene-terephthalate (PETE) graft aortitis caused by A. niger, a rare fungal agent. Early diagnosis with frequent transoesophageal echocardiography (TEE) and a prompt surgical intervention coupled with optimal antifungal therapy are still the only option to reduce the exceedingly high mortality and morbidity.

Abstract

This work was aimed at estimating the carcinogenic and non-carcinogenic health risks due to heavy metals on children and adults living in the vicinity of Shanono and Bagwai gold mining environs, Kano state, Nigeria. Flame atomic absorption spectrophotometry was used to obtain the concentrations of the heavy metals Zn, Cu, Cd, Cr, Pb, As, Cr, Mn, Fe and Ni in (40) soils, (8) drinking water and (8) edible plant samples from artisanal gold mining villages within Shanono and Bagwai environs. The obtained concentrations were used to estimate the non-cancer and cancer risks due to exposure from these metals using models provided by the United State Environmental protection Agency for the population ages. The overall hazard index was found to be 0.125 for children and 0.810 for adults and was largely contributed by Cr, As and Co. The overall total excess lifetime cancer risk was majorly contributed by Cr and As and was estimated as 5.77E−06 for children and 7.07E−06 for adults. The overall hazard index and Excess lifetime cancer risks were below the USEPA threshold limit for non-carcinogenic and carcinogenic risks respectively. Therefore, the exposed population ages are unlikely to experience any adverse carcinogenic or non-carcinogenic risks.
