Effects of Housing Modifications on the Management of Pigs and Growth Performance
Pig industry in Nigeria is an important arm of the livestock sub-sector in the overall agricultural sector. The comfort of Pigs is determined by effective environmental temperature. It combines the effect of air temperature, flooring, and bedding. The aim of this study is to investigate the impact of different intensive housing systems on the feed consumption level, weight gain and welfare of pigs fed with the same feed (diet) under different housing systems for 8 weeks. Nine Pigs were purchased from a reputable commercial farm and were divided into 3 treatment groups, T1, T2 and T3. T1 is a well built pen with cemented wall and floor. T2 is a pen built with bamboo wall, and cemented floor. T3 is built with bamboo wall without cemented floor – bare loamy soil. The Pigs were raised for eight weeks. The feed given and weight gained for eight weeks were recorded and analysed using ANOVA. Considering the consumption levels of all treatments, T2 had the lowest feed intake compared to other treatments. T2 had the highest weight gain while T3had the lowest. It is hereby concluded that T3 presented the best result as regards feed consumption, cost of construction and ease of management. Although it presented the lowest weight gain which is attributable to the initial weight and tipping of the feed trough (feed wastage). However, feed wastage can be minimized by using firmer feed trough
Phytochemical and Antimicrobial Properties of Oil Extracts from the Seeds of Ricinodendron heudelotii
Objective: The aim of this project is to extract the chemical components of various parts of this tree and to characterize the constituents
of these extracts and to test for their biological activity. Methodology: Agar-well diffusion assay was used to determine the antimicrobial
activity of the oil extract on the test isolates: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus cereus and
the yeast Candida albicans. The Minimum Inhibitory Concentration (MIC) for each test organism was determined by the broth dilution
method using 0.5 McFarland’s standard. Results: Preliminary proximate and phytochemical analysis of the oil extracts from the seed
showed the presence of the following minerals, Na, K, Ca, Mg, Mn, Fe, Cu and Zn as well as the following family of compounds: Steroids,
saponin and terpenoids. Antimicrobial and antibacterial studies also revealed that the oil extract was active against Gram’s negative and
positive bacteria and fungi. The test organisms were Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus
cereus and the yeast Candida albicans. Pseudomonas aeruginosa was resistant to the oil extract at all the concentrations used.
Conclusion: Amongst the bacteria used, highest MIC of 150 mg mLG1 was recorded for Staphylococcus aureus , while lowest MIC
of 50 mg mLG1 was observed in E. coli . Highest activity was observed against the fungus, Candida albicans with MIC of 25 mg mLG
Characterization, Proximate Composition and Evaluation of Antimicrobial Activity of Seed Oil of Bauhinia tomentosa
Background: This study was carried out to investigate proximate composition, phytochemical profile and antimicrobial activity of the
spectroscopically characterized seed oil of Bauhinia tomentosa . Materials and method: The characterization was carried out using FT-IR,
mass spectra, 1H- and 13C-NMR. Results: The results from the proximate analysis showed the presence of crude protein 30.36±0.98%,
crude fibre 26.00±0.69%, carbohydrate 25.32±0.57%, moisture content 12.04±0.39%, ash content 4.00±0.15% and fat content
2.28±0.09%. The phytochemical screening revealed the presence of alkaloids, flavonoids, saponins, terpenes, cardiac glycosides, sterols,
anthraquinones and tannins in varying degrees. The mineral determination showed that the seed oil contained iron (3.10±0.01 mg kgG1),
manganese (0.38±0.01 mg kgG1), while cadmium (0.0 mg kgG1), lead (0.0 mg kgG1) and nickel (0.0 mg kgG1) were not detected. The
extracted seed oil was investigated for antimicrobial efficiency against four bacterial isolates and two fungal, wherein gentamicin and
clotrimazole were the clinical standard antibiotic and antifungal agents, respectively. Conclusion: The antimicrobial activity result revealed
the sample to be bioactive and of great pharmaceutical potential with MIC value of 6.25 and <3.625 mg mLG1 against Escherichia coli
and Candida albican, respectively. Due to high nutritional values and broad antimicrobial properties, the seed oil of Bauhinia tomentosa
has nutraceutical potentials, which might pave way for its use as an alternative nutrient source for mankind or for industrial purpose

Preliminary Study on the Potassium content of Nigerian Bananas and the Methanolic Extraction, Phytochemical and Antimicrobial Studies of Oils from Banana Peels
Banana is eaten all over the world by all
sections of the population. It is known to contain potassium
and it has been suggested that it could serve as a source of
potassium. Recently, a valuable chemical component, a
lectin, called BanLec, was isolated from banana fruit and
found to possess anti-HIV-1 activity. However, the peels of
banana are thrown away as rubbish and farmers are known
to use them as feed for their animals. It is therefore
necessary to determine the potassium content of some
Nigerian bananas and to also extract the oils from their
peels. The components of the extracted oils are to be
determined and tested for their biological activity. The
potassium content of five (5) varieties of Nigerian bananas
(Dwarf Cavendish AAA GP; Lady Finger AA GP; Dwarf
Chinese Double; Double Dwarf Senorata AA GP; Giant
Cavendish (Williams) AAA GP and Dwarf Red AAA GP)
was determined using flame photometer. The potassium
content varied from 0.15 mg/g (Dwarf Red) to 1.80 mg/g
(Lady Finger). Compared to the value of 358 mg per 100 g
reported in the literature, these values are very low and
considerable lower than the RDA of 4700 mg. The conclusion
is that Nigerian bananas will not be a viable source of
potassium for candidates with potassium deficiency. A
report on the methanolic extract of oil from their peels is
given. Two (2) of the five (5) varieties were chosen and
methanolic extraction of oils from their peels was
undertaken. The crude extract was subjected to
phytochemical analysis, which revealed the presence of the
following of steroids, saponin and terpenoids,
anthraquinones and tannins. A report is also given on
antimicrobial studies of the methanolic extracts, which
revealed that the oils were effective against some bacteria
Return for prenatal care and childbirth services among Nigerian women using primary health care facilities
Commonly, women from low socio‐economic background are vul‐
nerable to pregnancy‐related complications (Iliyasu, Abubakar,
Galadanci, & Aliyu, 2010; Obiechina, Okolie, Eleje, Okechukwu, &
Anemeje, 2011). The peculiarity of their vulnerability predisposes
them to finding quicker and cheaper avenues to seek health care.
The primary health care (PHC) maternity facilities are to serve this
large population of women and their newborns. Services in Nigerian
PHC facilities are not completely free, and the costs of available
services are relatively determined by staff working in the facilitie

INTRODUCTION: Worldwide, 2 million patients aged 18-50 years suffer a stroke each year, and this number is increasing. Knowledge about global distribution of risk factors and aetiologies, and information about prognosis and optimal secondary prevention in young stroke patients are limited. This limits evidence-based treatment and hampers the provision of appropriate information regarding the causes of stroke, risk factors and prognosis of young stroke patients. METHODS AND ANALYSIS: The Global Outcome Assessment Life-long after stroke in young adults (GOAL) initiative aims to perform a global individual patient data meta-analysis with existing data from young stroke cohorts worldwide. All patients aged 18-50 years with ischaemic stroke or intracerebral haemorrhage will be included. Outcomes will be the distribution of stroke aetiology and (vascular) risk factors, functional outcome after stroke, risk of recurrent vascular events and death and finally the use of secondary prevention. Subgroup analyses will be made based on age, gender, aetiology, ethnicity and climate of residence. ETHICS AND DISSEMINATION: Ethical approval for the GOAL study has already been obtained from the Medical Review Ethics Committee region Arnhem-Nijmegen. Additionally and when necessary, approval will also be obtained from national or local institutional review boards in the participating centres. When needed, a standardised data transfer agreement will be provided for participating centres. We plan dissemination of our results in peer-reviewed international scientific journals and through conference presentations. We expect that the results of this unique study will lead to better understanding of worldwide differences in risk factors, causes and outcome of young stroke patients
Novel functional insights into ischemic stroke biology provided by the first genome-wide association study of stroke in indigenous Africans
\ua9 The Author(s) 2024. Background: African ancestry populations have the highest burden of stroke worldwide, yet the genetic basis of stroke in these populations is obscure. The Stroke Investigative Research and Educational Network (SIREN) is a multicenter study involving 16 sites in West Africa. We conducted the first-ever genome-wide association study (GWAS) of stroke in indigenous Africans. Methods: Cases were consecutively recruited consenting adults (aged > 18 years) with neuroimaging-confirmed ischemic stroke. Stroke-free controls were ascertained using a locally validated Questionnaire for Verifying Stroke-Free Status. DNA genotyping with the H3Africa array was performed, and following initial quality control, GWAS datasets were imputed into the NIH Trans-Omics for Precision Medicine (TOPMed) release2 from BioData Catalyst. Furthermore, we performed fine-mapping, trans-ethnic meta-analysis, and in silico functional characterization to identify likely causal variants with a functional interpretation. Results: We observed genome-wide significant (P-value < 5.0E−8) SNPs associations near AADACL2 and miRNA (MIR5186) genes in chromosome 3 after adjusting for hypertension, diabetes, dyslipidemia, and cardiac status in the base model as covariates. SNPs near the miRNA (MIR4458) gene in chromosome 5 were also associated with stroke (P-value < 1.0E−6). The putative genes near AADACL2, MIR5186, and MIR4458 genes were protective and novel. SNPs associations with stroke in chromosome 2 were more than 77 kb from the closest gene LINC01854 and SNPs in chromosome 7 were more than 116 kb to the closest gene LINC01446 (P-value < 1.0E−6). In addition, we observed SNPs in genes STXBP5-AS1 (chromosome 6), GALTN9 (chromosome 12), FANCA (chromosome 16), and DLGAP1 (chromosome 18) (P-value < 1.0E−6). Both genomic regions near genes AADACL2 and MIR4458 remained significant following fine mapping. Conclusions: Our findings identify potential roles of regulatory miRNA, intergenic non-coding DNA, and intronic non-coding RNA in the biology of ischemic stroke. These findings reveal new molecular targets that promise to help close the current gaps in accurate African ancestry-based genetic stroke’s risk prediction and development of new targeted interventions to prevent or treat stroke
Transfer of newborns to neonatal care unit: a registry based study in Northern Tanzania
<p>Abstract</p> <p>Background</p> <p>Reduction in neonatal mortality has been slower than anticipated in many low income countries including Tanzania. Adequate neonatal care may contribute to reduced mortality. We studied factors associated with transfer of babies to a neonatal care unit (NCU) in data from a birth registry at Kilimanjaro Christian Medical Centre (KCMC) in Tanzania.</p> <p>Methods</p> <p>A total of 21 206 singleton live births registered from 2000 to 2008 were included. Multivariable analysis was carried out to study neonatal transfer to NCU by socio-demographic factors, pregnancy complications and measures of the condition of the newborn.</p> <p>Results</p> <p>A total of 3190 (15%) newborn singletons were transferred to the NCU. As expected, neonatal transfer was strongly associated with specific conditions of the baby including birth weight above 4000 g (relative risk (RR) = 7.2; 95% confidence interval (CI) 6.5-8.0) or below 1500 g (RR = 3.0; 95% CI: 2.3-4.0), five minutes Apgar score less than 7 (RR = 4.0; 95% CI: 3.4-4.6), and preterm birth before 34 weeks of gestation (RR = 1.8; 95% CI: 1.5-2.1). However, pregnancy- and delivery-related conditions like premature rupture of membrane (RR = 2.3; 95% CI: 1.9-2.7), preeclampsia (RR = 1.3; 95% CI: 1.1-1.5), other vaginal delivery (RR = 2.2; 95% CI: 1.7-2.9) and caesarean section (RR = 1.9; 95% CI: 1.8-2.1) were also significantly associated with transfer. Birth to a first born child was associated with increased likelihood of transfer (relative risk (RR) 1.4; 95% CI: 1.2-1.5), while the likelihood was reduced (RR = 0.5; 95% CI: 0.3-0.9) when the father had no education.</p> <p>Conclusions</p> <p>In addition to strong associations between neonatal transfer and classical neonatal risk factors for morbidity and mortality, some pregnancy-related and demographic factors were predictors of neonatal transfer. Overall, transfer was more likely for babies with signs of poor health status or a complicated pregnancy. Except for a possibly reduced use of transfer for babies of non-educated fathers and a high transfer rate for first born babies, there were no signs that transfer was based on non-medical indications.</p
