Governance and the challenge of socio-economic development in Nigeria.

Various factors are said to be responsible for Nigeria’s current status as an underdeveloped country. These range from historical colonial experience, political instability, the monoculture nature of the national economy, and the persistent lack of commitment to focused development strategies on the part of the political elites. The most popular among the prescriptions for tackling the phenomenon of underdevelopment emphasized macroeconomic policies, economic diversification, transparency and accountability in governance and even direct distribution of resource proceeds to the general population. These solutions have not been able to adequately address Nigeria’s development challenges. However, the crucial role of the regulatory institutions, especially their oversight functions, has arguably been the missing link in establishing the complimentary relationship between governance and development in Nigeria. This paper discusses the importance of governance institutions as a fundamental determinant of robust and sustainable social and economic development in Nigeria.Keywords: Democracy, Corruption, Governance, Socio-economic developmen

Impact of organic and inorganic fertilizers on growth, fruit yield, nutritional and lycopene contents of three varieties of tomato (Lycopersicon esculentum (L.) Mill) in Ogbomoso, Nigeria

Field experiments were carried out to assess the impact of 100% NPK fertilizer recommendation (300 kg NPK 20:10:10), 100% Tithonia compost (TC), 75% NPK + 25% TC, 50% NPK + 50% TC, 25% NPK + 75% TC and control (non-fertilized plant) on the growth, fruit yield, nutritional and lycopene contents of three tomato varieties (Raoma VF; Ogbomoso local and Califonia wonder). The experiment was a split plot fitted into a randomized complete block design replicated three times. Data were collected on growth and reproductive parameters, fruit and seed attributes, and fruit proximate and nutritional contents. Data collected were subjected to analysis of variance to determine significant means. Significant varietal  differences were observed among the tomato varieties in terms of growth, fruit yield and nutritional  attributes. The plant dry matter yield was highest in Ogbomoso local and least in Roma VF. Fruit yield  obtained with Ogbomoso local was 45 and 56% higher than what was obtained for Roma VF and Califonia  wonder, respectively. In terms of vitamin C content, Roma VF fertilized with 50% NPK + 50% TC gave  the highest value which is 23 to 67% higher than values obtained from the other treatment combinations.  Again, irrespective of variety, organically grown tomato contains higher content of lycopene. It was also observed that the higher the proportion of TC compost in the treatments, the better the lycopene content. It could be concluded that the use of organic fertilizer has potential in improving the growth, fruit yield and nutritional contents of any of the three tomato varieties studied. Key words: Lycopersicon esculentum, compost, inorganic fertilizers, fruit yield, nutritional quality, lycopene content.Abbreviation: TC, Tithonia compost; WAT, week after transplanting; TSS, total soluble solid

Resistant plasmid profile analysis of multidrug resistant Escherichia coli isolated from urinary tract infections in Abeokuta, Nigeria

Background: Multi-drug resistant Escherichia coli has become a major threat and cause of many urinary tract infections (UTIs) in Abeokuta, Nigeria.Objectives: This study was carried out to determine the resistant plasmids of multidrug resistant Escherichia coli isolated from (Urinary tract infections)UTIs in Abeokuta.Methods: A total of 120 Escherichia coli isolates were obtained from urine samples collected from patients attending inpatient and outpatient clinics presenting UTI; with their biodata. Antibiotics susceptibility was performed and multi-drug resistant isolates were selected for plasmid profiling. Plasmids were extracted by the alkaline lysis method, electrophoresed on 0.8% agarose gel and profiled using a gel-photo documentation system gel.Results: Escherichia coli isolates obtained shows high resistance to cloxacillin (92.5%), amoxicillin (90.8%), ampicillin (90.8%), erythromycin (75.8%), cotrimoxazole (70.0%), streptomycin (70.0%) and tetracycline (68.3%) while 85.8% and 84.2% were susceptible to gentamycin and ceftazidime respectively. Sixteen Escherichia coli strains were observed to be resistant to more than two classes of antibiotics. The resistant plasmid DNA was detectable in 6(37.5%) of the 16 multidrug resistant Escherichia coli having single sized plasmids of the same weight 854bp and were all resistant to erythromycin, cefuroxime, cloxacillin, amoxicillin, ampicillin and cotrimoxazole.Conclusion: This study has highlighted the emergence of multidrug resistant R-plasmids among Escherichia coli causing urinary tract infections in Abeokuta, Nigeria. There is a high level of resistance to many antimicrobials that are frequently used in Abeokuta, Nigeria.Keywords: Escherichia coli, UTI, R-plasmid, multidrug resis

Parents' Acceptability and Health Workers' Perspectives of Pneumococcal Conjugate Vaccination for Under-Fives in Ile-Ife, Nigeria

Background: Pneumococcus, apart from being the commonest bacterial cause of Respiratory tract infections (RTIs) also causes a wide array of morbidities which can all be prevented with the administration of potent Pneumococcal conjugate vaccine. Despite its effectiveness and availability, Pneumococcal vaccines are not part of routine immunization in Nigeria. This study assessed parents' acceptability and health worker's perspectives of Pneumococcal Conjugate Vaccination for under-fives.Methods:  The cross-sectional survey was conducted in Ife Central Local Government Area, Osun state. An interviewer-administered questionnaire was used to collect information from 400 parents of under-fives selected via multi-stage random sampling. In-depth interviews were conducted for the heads of immunization units in four selected facilities in the local government area. Data were analysed using SPSS version-16.Result: More respondents were females, married and had tertiary education. About three-fifth (59.2%) of parents had good knowledge about RTIs though majority (79.00%) were unaware of Pneumococcal Conjugate Vaccine (PCV). most parents (93.5%) were willing to accept PCV for their children but only 43.5% of them could afford to pay for the cost of the vaccine at the prevailing market price. Most health workers (three out of four) interviewed were not aware of PCV. Most parents (96.25%) and all health workers interviewed wanted PCV incorporated into the National Program on Immunization (NPI). Parents with good knowledge about respiratory tract infections (RTIs) were significantly willing to accept PCV for their underfives (p= 0.005). Younger parents less than 35years, parents with lower educational attainments and low income groups significantly could not afford to pay for the cost of vaccines. (p=0.014, 0.001 and <0.001 respectively).Conclusion: Though almost three fifth of parents surveyed had good knowledge about RTIs, awareness about PCV was poor and most of them were unable to afford PCV. There is an overwhelming need to incorporate PCV in to the NPI, as both parents and health workers agreed. Aside from overcoming a major financial barrier to vaccine access, this will also make PCV widely available to parents who are already willing to accept the vaccine for their children.Keywords: Parents' Acceptability, Pneumococcal conjugate Vaccinatio

Antibiotic Resistance Profile of Bacteria isolated from Septicaemia Cases in a Tertiary Health Care in Abeokuta

ABSTRACT: The term septicaemia is often used in describing severe bacteraemic infections or a condition in which the blood serves as a site of bacteria multiplication. A total of 120 blood culture samples were collected during year 2011 to 2012. Bacteria isolated were characterized and the antibiotic sensitivity patterns were determined. The antibiotic sensitivity was carried out using Kirby-Bauer diffusion method. Bacteria isolated include Escherichia coli, Klebsiella sp, Streptococcus pneumoniae and Pseudomonas aeruginosa. The highest number of bacteria was found among patient age 10 years. Escherichia coli accounted for 12(46.2%) of the bacteria isolated while Pseudomonas aeruginosa, Klebsiella sp and Streptococcus pneumoniae accounted for 6(23.1%), 6(23.1%) and 2(7.6%) respectively. The least prevalent isolate Streptococcus pneumoniae was found only in age group 10. Ceftazidime and Levoxin showed high sensitivity rate to most of the bacterial isolates. From this study, the uncontrolled use of antibiotics may have implication for emerging resistance of bacteria to commonly -used antibiotics.

A Cross-sectional Survey of the Willingness of Tertiary Hospital Staff to Donate Blood in Sagamu, Nigeria

Background: Available donor blood rarely meets the demand in sub-Saharan Africa due to obstacles to blood donation. Willingness to donate blood is adjudged an important step to the actual practice of donating blood. Objective: To assess the willingness of the members of staff of the hospital to donate blood and determine factors affecting their willingness or otherwise. Methods: This was a descriptive cross-sectional study. A proportional allocation of participants was carried out at the various departments in the hospital using self-administered questionnaire. Results: Overall, 183 (73%) of the 246 respondents expressed willingness to donate blood, 111(45%) of whom have been asked to donate blood in the past. Only 91(37%) had donated blood in the past. Significantly higher proportion of health staff showed the willingness to donate blood generally and voluntarily compared to non-health staff. Significantly higher proportion of respondents with tertiary education showed the willingness to donate blood. Two hundred and eighteen (88.8%) were willing to donate blood to help the patient in need while fear of exposure to HIV infection, needle prick and dizziness constituted the major factors discouraging blood donation (19.9%, 18.7% and 18.3% respectively). Conclusion: Willingness to donate blood was mostly based on the primordial motivation of helping the patient in need which does not translate to blood donation. There is a need to improve awareness and advocacy on blood donation among hospital staff and the general population

Cataract burden and uptake of cataract surgical services: Results from a population-based survey.

Background: Global estimates suggest that approximately two thirds of the blind population are females. Cataract accounts for over half of all blindness worldwide. Surgery is curative. However, in many parts of Sub-Saharan Africa, people have limited access to services. We estimated the burden of “operable cataract” and assessed for any gender inequality in the uptake of cataract surgical services.Method: Using a multi-staged stratified random sampling with probability proportional to size, three local government areas in Plateau state were selected. The study instrument was the Rapid Assessment of Cataract Surgical Services (RACSS) Proforma.Results: 4115 persons were examined (coverage: 98%). Prevalence of “operable cataract” (VA <6/60 in the better eye) was 3.3%, more among females 78 (3.6%) than males 57 (2.9%). Prevalence of unilateral “operable cataract” was 7.2%. The Cataract surgical coverage (persons) was 43.8%, among males it was 49.1% and for females 39.1% ( p>0.05.) The burden of cataract would have been reduced by 28.1% if the CSC was equal for both genders.Conclusion: The burden of cataract is high; uptake of services is low especially among females.Keywords: Epidemiology, Africa, Surgery, Gender, Ocula

Hydrolysis Catalysis of <i>Miscanthus</i> Xylan to Xylose Using Weak-Acid Surface Sites

Adsorption and hydrolysis of xylan polysaccharides extracted from <i>Miscanthus</i> biomass are demonstrated, using surface-functionalized MCN (mesoporous carbon nanoparticle) materials that comprise weak-acid sites, at a pH corresponding to biomass extract. Extracted xylan polysaccharides consist of a peak molecular weight of 2008 g/mol according to GPC (gel-permeation chromatography), corresponding to approximately 15 xylose repeat units, and, a calculated length of 7 nm and radius of gyration of 2.0 nm based on molecular dynamics simulations. A highly active material for the adsorption and depolymerization of xylan is a hydrothermally treated sulfonated MCN material, which consists of 90% weak-acid sites. In spite of the large polysaccharide size relative to its 1.6 nm pore radius, this material adsorbs up to 76% of xylan strands from extract solution, at a weight loading of 29% relative to MCN. Starting with a 9.7% xylose yield in <i>Miscanthus</i> extract, this material hydrolyzes extracted xylan to xylose, and achieves a 74.1% xylose yield, compared with 24.1% yield for the background reaction in acetate buffer, at 150 °C for 4 h. Catalytic comparisons with other MCN-based materials highlight the role of confinement and weak-acid surface sites, and provide some correlation between activity and phenolic OH acid-site density. However, the lack of a directly proportional correlation between weak-acid site density and catalyzed hydrolysis rate signifies that only a fraction of weak-acid surface sites are catalytically active, and this is likely to be the sites that are present in a high local concentration on the surface, which would be consistent with previously observed trends in the hydrolysis catalysis of chemisorbed glucans on inorganic-oxide surfaces
