Factors Affecting Soil Quality Maintenance in Northern Katsina State, Nigeria

This study was set-up to determine the key factors affecting soil quality maintenance in Kaita, Mai-adua and Mashi local government areas (LGAs) of Katsina state, Nigeria. Two hundred and forty soil samples were collected and 600 questionnaires administered to obtain information on the various forms of activities affecting soil quality maintenance in the area. The soil samples were analyzed for selected physical and chemical quality indices. Factors affecting soil quality maintenance in the area according to the findings are natural and man-induced, including agricultural practices in general and deforestation, soil degradation and erosion, as well as biodiversity loss in particular. The results also indicated that values of the selected elements affecting soil quality in all the 3 LGAs studied fell below minimum standards. Soils in 2 of the LGAs (Mai-adua and Mashi) were concluded to be sensitive to plant growth. Caution should, however, be exercised for soils of Kaita LGA that are extremely sensitive so as not to continue to increase in salinity. It is recommended that farm management practices in the area should be improved and use of irrigation water encouraged among farmers to check salt accumulation.Keywords: Soil Quality, Soil Quality Maintenance, Factors Affecting Soil Qualit

Snake-Bite Gangrene in Children: A Report of Two Cases

Snake-bite can be both life and limb threatening, especially when there is envenomation. Early intervention in a fairly equipped health facility can go a long way in preventing the morbidity and mortality that can result from delay in initiating treatment. In this paper we report two cases of snakebite to the lower limbs in children that were both complicated by gangrene which led to major limb amputation in both. These are avoidable complications that should have been averted by appropriate care immediately after the snake-bite. Key words:Snake-bite, Gangrene, Childre

The implications of agro-chemical compounds (fertilizers, pesticides and herbicides) on farming/aquaculture activities in the lake-Chad and its possible current/future social effects

Field survey and Laboratory analysis were carried out to determine the implications of agro-chemicals effluent on Lake Chad water. Historically societies used traditional farming methods involving rainfed agriculture and limited ground water withdrawal with irrigation though an ancient practice, it affected only small parts of the world. Water in Lake Chad is facing serious environmental problems from prolong drought to desertification, pollution and biodiversity reduction. The use of water for extensive agriculture by the lakes riparian states is reducing the water and stressing the ecological balance affecting the organisms depending on it and also its availability to its inhabitants. Water quality is also an important issue in the Lake Chad especially where the rainfall being the natural input into the system is small, greater risk of fertilizer, pesticides, and other agro-chemicals/inputs, runoff from the soil to the lake water and also salt accumulation threat are imminent. The assessment of the Lake Chad water resource quality was therefore carried out carefully while understanding the linkage and interaction with Agro-chemicals using stratified random sampling method for data acquisition and assessment on the site. The results of the experiment indicated that five parameters, namely, PH, Cadmium, Iron, Magnesium and chlorine have contaminant levels above the threshold limit as major sources of pollution in the lake with possible existing and future problem. As a result of the adverse effect of the agrochemicals runoff in the Chad water at Kirinowa. It can be concluded from the results of this study that the lake is under pollution of metals from sources of agricultural operations, due to indiscriminate application of pesticides, herbicides and fertilizers.Key words: Lake Chad, Agro-chemicals, Accumulation, Contamination, Pollution

ANTIFUNGAL EFFECTS OF TAPINANTHUS GLOBIFERUS GROWING ON VITEXDONIANA AGAINST SOME FUNGAL ISOLATES

Objective: Fungal infections are the major cause of many skin diseases, especially in developing countries. Natural products of medicinal value represent a potential source of chemotherapeutic agents. Tapinanthus globiferus has been used extensively in ethnomedicine for the treatment hypertension, ulcer, cancer, diabetes and fungal infections without a scientific basis. This work was aimed at screening the phytochemical constituents and evaluating the antifungal properties of methanol leaf extract its ethyl acetate and n-butanol fractions of T. globiferus against some clinical fungal isolates including Candida albicans, Trychophyton mentagrophytes, Trychophyton  rubrum and Aspergillus niger using agar well diffusion and broth micro-dilution techniques. Methods: Preliminary screening of phytochemical constituents of extract and fractions of T. globiferus indicated the presence of carbohydrates, alkaloids, glycosides, tannins, flavonoids,  saponins, steroids and triterpenes. Results: The methanol extract and its fractions demonstrated significant (P<0.05) antifungal effect  against all the test organisms with mean zone of inhibition ranging from 27.83±0.16 – 14.46±0.29mm which was higher compared to that of the standard drug, Fluconazole (26.1±0.44 –18.49±0.16 mm). The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of the extract ranged between 6.25 – 25.0 mg/mL; ethyl acetate fraction had 3.13 – 25.0 mg/mL while n-butanol fraction had the least MIC ranging from 0.39-12.5 mg/mL against the test organisms. Conclusion: Study concluded that T. globiferus have good antifungal activity validating the ethnomedicinal claim for the use of the plant in the treating fungal diseases.                           Peer Review History: Received 2 January 2020;   Revised 25 February; Accepted 1 March, Available online 15 March 2020 Academic Editor: Dr. Ali Abdullah Al-yahawi, Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Quality of life and visual function in Nigeria: findings from the National Survey of Blindness and Visual Impairment

Aims To assess associations of visual function (VF) and quality of life (QOL) by visual acuity (VA), causes of blindness and types of cataract procedures in Nigeria. Methods Multi-stage stratified cluster random sampling was used to identify a nationally representative sample of persons aged >= 40 years. VF/QOL questionnaires were administered to participants with VA = 6/12. Results VF/QOL questionnaires were administered to 2076 participants. Spearman's rank correlation showed a strong correlation between decreasing VA and VF/QOL scores (p< 0.0001) with greatest impact on social (p< 0.0001) and mobility-related activities (p< 0.0001). People who were blind due to glaucoma had lower VF and QOL scores than those who were blind due to cataract. Mean VF and QOL scores were lower after couching compared with conventional cataract surgery (mean VF score=51.0 vs 63.0 and mean QOL score=71.3 vs 79.3). Finally, VF and QOL scores were lower among populations with specific characteristics. Conclusions Populations with the following characteristics should be targeted to improve VF and QOL: people who are blind, older people, women, manual labourers, people living in rural areas, those living in the northern geopolitical zones, those practising Islamic and Traditionalism faith, those not currently married and those who have undergone couching

Anti-Inflammatory Activity of Crude Saponin Extracts from Five Nigerian Medicinal Plants

Crude saponin extracts of five medicinal plants used in the treatment of inflammatory diseases like rheumatoid arthritis, gout and haemorrhoids were screened for anti-inflammatory activity using carrageenan-induced rat paw oedema test. These plants were the whole plant of Schwenkia americana Linn (WSA), the rhizomes of Asparagus africanus Lam (RAA), the leaves of Dichrostachys cinerea Linn (LDC), the stem bark of Ficus iteophylla Miq (BFI) and the leaves of Indigofera pulchra Willd (LIP). A modify traditional method of crude saponins extraction was used to give the following percentage yields: WSA-2.74%, RAA-3.59%, LDC-1.62%, BFI-0.81% and LIP-1.57% respectively. Thin-layer chromatography was used to identify the type of saponins present in the extracts. The acute toxicity study of the crude saponin extracts in mice gave the following intraperitoneal LD50: WSA-471.2mg/kg, RAA- 1264.9mg/kg, LDC-1264.9mg/kg, BFI-118.3mg/kg and LIP-1264.9mg/kg respectively.&nbsp; The antiinflammatory study of the extracts showed statistically significant (P&lt;0.05) decreases in the rat paw-oedema as compared to the control. The percentage inhibitions of the extracts after four hours were as follow: WSA-61%, RAA-55%, LDC-72%, BFI-66% and LIP-40% respectively. These values were found to be comparable to that of ketoprofen-63%. The study showed that the antiinflammatory properties attributable to these plants may be due to their saponins contents.Keywords: - Asparagus africanus, Dichrostachys cinerea, Ficus iteophylla, Indigofera pulchra, Schwenkia americana, Saponin,Anti-inflammatory activity, Carrageenan, TLC

Profile and management of central nervous system malformations in a tertiary hospital

Central Nervous System (CNS) malformations rank among the commonest malformations. These may be identified in utero or noticed immediately after birth. Most studies showed Myelomeningocoele, a Neural Tube Defect (NTD) to be the commonest. Severe defects have a significant impact on long term disability. While some are preventable, most are surgically managed. Objective: To study the profile and management of CNS malformation in a tertiary hospital. Method: we undertook a 3-year retrospective study of the profile and surgical management, including the postoperative complications among Neonates admitted into the Special Care Baby Unit (SCBU). Data on place of delivery, Gender, Gestational age, Mode of delivery, Prenatal Diagnosis (Ultrasound Scan), types of malformations, types of surgeries, and postoperative complications were retrieved. Result: We found 71 patients with CNS anomalies (31.8% of all congenital anomalies), in delivery 10 (14.1%), out delivery 46(64.8%). Male=43, females=28. Term gestation 66 (93%), preterm 3(4.2%), post-term 2(2.8%). Delivered by Vagina (SVD) in 65(91.6%), Caesarean section 4(5.6%), and undocumented in 4(5.6%). Prenatal diagnosis in only 3(4.2%). Myelomeningocoele was 35(49.3%), meningocoele was 9(12.7%), Hydrocephalus was 18(25.3%), anencephaly was 1(1.4%), occipital Encephalocoele was 6(8.5%), Sincipital Encephalocoele was 2(2.8%). Operated on 53(75%), LAMA/lost to follow was 13(18%), preoperative death was 5(7%). Excision and closure of Neural Tube Defect were 34(64.2%), VP Shunt was 13(24.5%), Excision and closure of occipital Encephalocoele were 5(9.4%) craniofacial excision and repair of Sincipital Encephalocoele was 1(1.9%). CSF leak in 4(28.6%), wound infection in 3(21.4%), shunt infection and obstruction in 2(14.3%) each. meningitis, hypertrophied scar, and pseudo meningocoele in 1(7.1%) each. Conclusion: The commonest CNS anomaly is a Myelomeningocoele a preventable condition, Sincipital Encephalocoele is not common in our environment. Concomitant treatment of hydrocephalus averts post excision CSF Leak

Black, Asian and Minority Ethnic groups in England are at increased risk of death from COVID-19: indirect standardisation of NHS mortality data [version 2; peer review: 2 approved, 1 approved with reservations]

Background: International and UK data suggest that Black, Asian and Minority Ethnic (BAME) groups are at increased risk of infection and death from COVID-19. We aimed to explore the risk of death in minority ethnic groups in England using data reported by NHS England. / Methods: We used NHS data on patients with a positive COVID-19 test who died in hospitals in England published on 28th April, with deaths by ethnicity available from 1st March 2020 up to 5pm on 21 April 2020. We undertook indirect standardisation of these data (using the whole population of England as the reference) to produce ethnic specific standardised mortality ratios (SMRs) adjusted for age and geographical region. / Results: The largest total number of deaths in minority ethnic groups were Indian (492 deaths) and Black Caribbean (460 deaths) groups. Adjusting for region we found a lower risk of death for White Irish (SMR 0.52; 95%CIs 0.45-0.60) and White British ethnic groups (0.88; 95%CIs 0.86-0.0.89), but increased risk of death for Black African (3.24; 95%CIs 2.90-3.62), Black Caribbean (2.21; 95%CIs 2.02-2.41), Pakistani (3.29; 95%CIs 2.96-3.64), Bangladeshi (2.41; 95%CIs 1.98-2.91) and Indian (1.70; 95%CIs 1.56-1.85) minority ethnic groups. / Conclusion: Our analysis adds to the evidence that BAME people are at increased risk of death from COVID-19 even after adjusting for geographical region. We believe there is an urgent need to take action to reduce the risk of death for BAME groups and better understand why some ethnic groups experience greater risk. Actions that are likely to reduce these inequities include ensuring adequate income protection (so that low paid and zero-hours contract workers can afford to follow social distancing recommendations), reducing occupational risks (such as ensuring adequate personal protective equipment), reducing barriers in accessing healthcare and providing culturally and linguistically appropriate public health communications

From the micro to the macro to improve health: microorganism ecology and society in teaching infectious disease epidemiology

Chronic and emerging infectious diseases and antimicrobial resistance remain a substantial global health threat. Microbiota are increasingly recognised to play an important role in health. Infections also have a profound effect beyond health, especially on global and local economies. To maximise health improvements, the field of infectious disease epidemiology needs to derive learning from ecology and traditional epidemiology. New methodologies and tools are transforming understanding of these systems, from a better understanding of socioeconomic, environmental, and cultural drivers of infection, to improved methods to detect microorganisms, describe the immunome, and understand the role of human microbiota. However, exploiting the potential of novel methods to improve global health remains elusive. We argue that to exploit these advances a shift is required in the teaching of infectious disease epidemiology to ensure that students are well versed in a breadth of disciplines, while maintaining core epidemiological skills. We discuss the following key points using a series of teaching vignettes: (1) integrated training in classic and novel techniques is needed to develop future scientists and professionals who can work from the micro (interactions between pathogens, their cohabiting microbiota, and the host at a molecular and cellular level), with the meso (the affected communities), and to the macro (wider contextual drivers of disease); (2) teach students to use a team-science multidisciplinary approach to effectively integrate biological, clinical, epidemiological, and social tools into public health; and (3) develop the intellectual skills to critically engage with emerging technologies and resolve evolving ethical dilemmas. Finally, students should appreciate that the voices of communities affected by infection need to be kept at the heart of their work
