Heavy metals and sensory evaluation of canned tuna fish

In this study, two heavy metals in canned tuna fish were determined after digestion by the AOAC methods. Mercury and Cadmium levels in canned tuna fish were determined by flame atomic absorption photometry. The results of this study indicate that canned tuna fish imported into the country have concentrations well below the petmissible FAO/WHO levels for these toxic metals. Their contribution to the body burden can therefore be considered negligible and the fish seem to be safe for human consumption. For the sensory evaluation, tuna flakes in vegetable oil (Starkist) from Ghana and light meat tuna chunks in sunflower oil (John West) from Thailand were the most preferred while tuna flakes in brine (John West) from Thailand is the least preferred

Introduction: MDR-TB poses a significant challenge to global management of TB. Laboratories in many countries among which include Nigeria are unable to evaluate drug resistance, and clinical predictors of MDR-TB might help target suspected patients.Method: The study was a cross sectional study design. Multistage sampling technique was employed in the selection of 403 tuberculosis patients. Data were analyzed using SPSS version 25. Level of significance was set at P<0.05.Results: Fifty three 53 (13.2%) of the total respondent had MDR-TB compare to national prevalence of 8% which is steeper among males 36(67.9%) (p>0.05). Education and Occupation shows a significant association with MDR-TB, (÷2=24.640, p = 0.007) and (÷2=14.416, p=0.006) respectively, smoking (r=0.074, p<0.05) and alcohol consumption (r=0.083, p>0.05) show no significant association with occurrence MDR-TB.Conclusion: Previous TB treatment and Adherence with treatment regimen were found to be the major risk factor for MDR-TB. Targeted educational intervention for patients and their contacts may minimize the non-adherence with prescribed TB treatment and lessen MDR-TB magnitude.

The roles of biochar and arbuscular mycorrhizal inoculation on selected soil biological properties and tomato performance

Field experiment was conducted to investigate the effects of biochar application and arbuscular mycorrhizal (AM) inoculation on selected soil biological characteristics, shoot P and fruit yield of two tomato genotypes. Result indicated that mycorrhizal inoculation significantly (p< 0.05) increased shoot P (0.72 g P kg-1) and number of AM spores (47.90 spores / 25 g soil) compared to non-mycorrhizal plants, but no significant difference was observed in tomato fruit yield, microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN). Application of 20 t ha-1 of biochar significantly (p< 0.05) increased tomato fruit yields and number of AM spores when compared with the control. However, 10 and 15 t ha-1 of biochar rates gave comparable performance as 20 t ha-1 of biochar in most cases. No significant differences were observed in shoot P, MBC and MBN among biochar rates. Thus, AM inoculation enhanced P nutrition while biochar improved AM spores abundance as well as tomato fruit yields. The 20 t ha-1 of biochar could be used to improve AM spores abundance as well as tomato fruit yields.Keywords: Biochar; AM Fungi; Biological Properties; Tomato Performanc

Retinopathy of prematurity in a tertiary facility: an initial report of a screening programme

Background: Retinopathy of prematurity (ROP) screening in Nigeria is at a nascent stage and at the moment there are no National guidelines for ROP screening in Nigeria. Thus it is desirable for screening programs to report findings amongst screened preterm infants in order to facilitate the  development of national ROP screening criteria and guidelines. The aim of this report is to describe the frequency, severity and risk factors for retinopathy of prematurity (ROP) among preterm and very low-birth-weight babies screened within the first year of initiating an ROP screening  program at a Nigerian tertiary facility. Methods: A cross-sectional study of infants born at less than 34 weeks gestational age; or with birth weight less than 1500g between May 2016 and May 2017. ROP screening examinations were performed by ophthalmologists with the use of an indirect ophthalmoscope, after pupillary dilation, in collaboration with the neonatology team. Information on gestational age at birth, birth weight, oxygen therapy and presence of other risk factors were recorded and analyzed. Results: A total of 74 infants were screened during the period. There were 36 (48.6%) males. Mean gestational age at birth was 29.6 (±2.35) weeks.  Mean birth weight was 1.26 (±0.27) kg with a range of 800 to 1950g. ROP was detected in 9 (12.2%) infants. Two (22.2%) of these had Threshold ROP. There was no significant difference between the mean birth weight and mean gestational age of the infants who had ROP compared to those  without ROP. The two infants with Threshold ROP were treated with intravitreal Bevazicumab and had regression of ROP. Conclusion: Retinopathy of prematurity was diagnosed in at risk infants in this facility. There is, therefore, a need to establish ROP screening  programs in all neonatal units across the country. In addition, established programs need to evaluate their screening criteria with a view towards  developing country-specific screening guidelines.

Parental Knowledge and Attitude of Adolescent Sexuality Education in Rural and Urban Communities of Ekiti State, Nigeria

Background: Parents play a key role in shaping the attitudes and behaviour of adolescents, thereby reducing risky sexual behaviour and promoting healthy sexual development. This study assessed and compared parental knowledge and attitude towards adolescent sexuality education (ASE) in rural and urban communities of Ekiti State, Nigeria.Materials and Methods: A comparative cross-sectional study of 800 parents (or guardians) of adolescents in selected rural and urban communities, recruited through a multi-stage sampling technique. An interviewer-administered semi-structured questionnaire was used to collect data. Data were analysed using SPSS version 20.Result: A significantly higher proportion of parents from the urban communities had a good knowledge of ASE (72.5% versus 66.0%, p-value 0.046). However, knowledge of safe sex and dating was low in both communities. About three-quarters of the respondents had a positive attitude towards ASE with no statistically significant difference in both rural and urban communities (p-value: 0.363).Conclusion: Parental knowledge of ASE is high in Ekiti State, and it is higher in the urban compared to the rural communities. Attitude towards ASE is high in both communities but not significantly different. However, the knowledge of the various components of ASE varies significantly amongst the communities. While it is recommended that government should create a supportive environment to assist parents in their roles as sexuality educators, parents should see sexuality education as their responsibility and also start the discussion early

Tracking development assistance for health and for COVID-19 : a review of development assistance, government, out-of-pocket, and other private spending on health for 204 countries and territories, 1990-2050

Background The rapid spread of COVID-19 renewed the focus on how health systems across the globe are financed, especially during public health emergencies. Development assistance is an important source of health financing in many low-income countries, yet little is known about how much of this funding was disbursed for COVID-19. We aimed to put development assistance for health for COVID-19 in the context of broader trends in global health financing, and to estimate total health spending from 1995 to 2050 and development assistance for COVID-19 in 2020. Methods We estimated domestic health spending and development assistance for health to generate total health-sector spending estimates for 204 countries and territories. We leveraged data from the WHO Global Health Expenditure Database to produce estimates of domestic health spending. To generate estimates for development assistance for health, we relied on project-level disbursement data from the major international development agencies' online databases and annual financial statements and reports for information on income sources. To adjust our estimates for 2020 to include disbursements related to COVID-19, we extracted project data on commitments and disbursements from a broader set of databases (because not all of the data sources used to estimate the historical series extend to 2020), including the UN Office of Humanitarian Assistance Financial Tracking Service and the International Aid Transparency Initiative. We reported all the historic and future spending estimates in inflation-adjusted 2020 US$, 2020 US$ per capita, purchasing-power parity-adjusted US$per capita, and as a proportion of gross domestic product. We used various models to generate future health spending to 2050. Findings In 2019, health spending globally reached$8. 8 trillion (95% uncertainty interval [UI] 8.7-8.8) or $1132 (1119-1143) per person. Spending on health varied within and across income groups and geographical regions. Of this total,$40.4 billion (0.5%, 95% UI 0.5-0.5) was development assistance for health provided to low-income and middle-income countries, which made up 24.6% (UI 24.0-25.1) of total spending in low-income countries. We estimate that $54.8 billion in development assistance for health was disbursed in 2020. Of this,$13.7 billion was targeted toward the COVID-19 health response. $12.3 billion was newly committed and$1.4 billion was repurposed from existing health projects. $3.1 billion (22.4$2.4 billion (17.9%) was for supply chain and logistics. Only $714.4 million (7.7$1519 (1448-1591) per person in 2050, although spending across countries is expected to remain varied. Interpretation Global health spending is expected to continue to grow, but remain unequally distributed between countries. We estimate that development organisations substantially increased the amount of development assistance for health provided in 2020. Continued efforts are needed to raise sufficient resources to mitigate the pandemic for the most vulnerable, and to help curtail the pandemic for all. Copyright (C) 2021 The Author(s).

Anemia prevalence in women of reproductive age in low- and middle-income countries between 2000 and 2018

Anemia is a globally widespread condition in women and is associated with reduced economic productivity and increased mortality worldwide. Here we map annual 2000–2018 geospatial estimates of anemia prevalence in women of reproductive age (15–49 years) across 82 low- and middle-income countries (LMICs), stratify anemia by severity and aggregate results to policy-relevant administrative and national levels. Additionally, we provide subnational disparity analyses to provide a comprehensive overview of anemia prevalence inequalities within these countries and predict progress toward the World Health Organization’s Global Nutrition Target (WHO GNT) to reduce anemia by half by 2030. Our results demonstrate widespread moderate improvements in overall anemia prevalence but identify only three LMICs with a high probability of achieving the WHO GNT by 2030 at a national scale, and no LMIC is expected to achieve the target in all their subnational administrative units. Our maps show where large within-country disparities occur, as well as areas likely to fall short of the WHO GNT, offering precision public health tools so that adequate resource allocation and subsequent interventions can be targeted to the most vulnerable populations.Peer reviewe

The study, thus, assessed the factors predisposing building elements to variation with a view to providing cost-design information that enhance construction project delivery, that is, on-time completion of project within budget. The building elements considered in this study include substructure, frame, upper floors, and roof. Data were collected using well-structured questionnaires administered on professionals in consulting firms, contracting firms, and client organizations in Lagos metropolis. Data analysis was done using descriptive and inferential statistics. The results of the analysis revealed nine factors through factor analysis that predispose substructure to variation, seven factors predispose frame, six factors predispose upper floors, and seven factors predispose roofs to variation during construction process in Nigeria

Knowledge and attitude of young male adults in two markets in metropolitan Lagos towards prostate cancer screening and awareness of prostate cancer symptoms

Prostate cancer is the second most common cancer in men and the fourth most common cancer in both sexes combined. It is a slow growing cancer and its morbidity and mortality can be reduced through regular screening. To assess the knowledge and attitude of young male adults in metropolitan Lagos towards prostate cancer screening, their awareness of prostate cancer symptoms and to identify socio-demographic factors that influence knowledge and attitude of young male adults towards prostate cancer screening. A descriptive cross-sectional study conducted among young male adults in two different markets in Lagos metropolis. Data was collected and analysed using SPSS version 21. Numerical and categorical variables were expressed as counts and/or percentages. Inferential statistics was performed using Chi Square test, with a level of significance set at p<0.05. Ethical approval was obtained from the Health Research Ethics Committee of the Lagos University Teaching Hospital. A total of 421 questionnaires were distributed with 95% response rate. One hundred and ninety (47.5%) had heard about prostate cancer. Majority of the respondents, 371 (92.8%) were not aware of prostate cancer symptoms. Three hundred and seven (77.8%) were also not aware of prostate cancer screening. Majority of the respondents, 305 (76.3%) indicated that they would like to be screened and to know more about prostate cancer screening (330 respondents, 82.5%). This study showed a poor knowledge of prostate cancer, its symptoms and prostate cancer screening among young male adults operating in two markets in Lagos, Nigeria
