Ameye, S, Adeyemo A, Eziyi J, Omonisi A, Olaofe O, Amusa Y.  2020.  Challenges in the management of a rare atypical case of malignant glomus tumour of the neck, 2020/06/30. 25 Abstract

We describe a case of malignant glomus tumour affecting the neck of a 24-year-old woman who presented with painful neck masses and amenorrhoea. Malignant glomus tumours of the neck are rare disease and can be confused with paragangliomas. After resection surgery, postoperative complications of bilateral chylothorax (without chylous fistula) and diabetes insipidus were successfully managed, and the patient remains well after long-term follow-up.

Bolaji, A, Oladejo A, Ebeagu S.  2020.  Diversity Studies in Vigna Species and Their Implications in Further Breeding, 2020/06/08. Abstract

Aims: To evaluate, identify and select superior genotypes with better agronomic traits with respect to insect resistance and yield components for the development of improved cowpea varieties. Study Design: The plants were raised using completely randomized design (CRD). Place and Duration of Study: Screen house of the Department of Botany, Obafemi Awolowo University, Ile-Ife, Nigeria, between between July 2017 and January 2018. Methodology: A total of 67 Vigna accessions consisting of 36 V. vexillata and 31 V. unguiculata species were evaluated and the quantitative and qualitative attributes of the various accessions studied were documented. The data obtained in the study were subjected to univariate analysis involving descriptive statistics, as well as multivariate analysis involving the General Linear Model (GLM) Analysis of Variance (ANOVA) and Principal Component Analysis (PCA). The differences among means of each variable were tested using the Duncan Multiple Range Test (DMRT) at ˂0.05 using System Analysis Software (SAS) version 9.13. Pearson Correlation Coefficient was also used to test the correlation among the quantitative attributes of the varieties studied. Results: The results of the investigation showed that there was significant variation in most of the quantitative attributes of the species studied though many of the qualitative vegetative attributes were considerably uniform. The Principal Component Analysis showed that some of the important traits that contributed significantly to the variation were number of days to seedling emergence, plant height, leaf length, leaf breadth, petiole length, pod length, pod breadth, seed length, seed breadth, number of seeds per pod and number of locules. Conclusion: From the findings obtained in this study, it could be concluded that the desirable traits of Tvnu1249 (V. vexillata) such as early maturity, and Tvnu72 (V. vexillata) with high percentage seed set and resistance to flower bud thrips could be transferred into Sanzi and Ifebrown (V. unguiculata varieties) with larger seed sizes and high percentage seed set through hybridization and other breeding techniques.

Ekundayo, O, Babalola O.  2020.  Sexual Risk Behaviour: The Roles of Impulsivity, Family Type and Peer Pressure Among Undergraduate Students in Nigeria, 2020/06/01. 13:15-23. Abstract

The study examined the influence of impulsivity on undergraduates’ sexual risk behaviour and also scrutinized the mediating roles of family type and peer pressure on undergraduates’ sexual risk behaviour in Southwestern Nigeria. The study was a descriptive survey that employed a multi-stage sampling procedure in which respondents were selected at different levels and stages. A total of 1080 respondents selected from six Universities participated in the study. Their age ranges from 15-19 years with a mean of 15.9±1.2 years. Data gathered through Impulsive Behaviour Scale and the Sexual Behaviour Inventory was analysed by t-test and ANCOVA. The result showed that impulsivity (t = 6.04, df =1078, p <0.05) had significant influence on the sexual risk behaviour of undergraduates in Southwestern Nigeria. The result further showed that age: F (2, 1077) = 18.20, p < 0.05; family type F (2, 1077) = 25.41, p <0. 05 and peer pressure F (2, 1077) = 53.13, p< 0.05 have an intervening impact on the influence of impulsivity F (2, 1073) = 1.37, p < 0.05) on sexual risk behaviour of the undergraduates. The study concluded that impulsivity enhances sexual risk behaviour of undergraduates in Southwestern Nigeria.

Famurewa, B, Oginni F, Aregbesola SB, Erhabor G.  2020.  Effects of maxillomandibular fixation and rigid internal fixation on pulmonary function in patients with mandibular fractures, 2020/02/01. 49 Abstract

Closed reduction and maxillomandibular fixation (MMF) is associated with airway obstruction. The ventilatory effect of open reduction and rigid internal fixation (ORIF) as an alternative treatment has not been determined. The aim of this study was to compare the effects of MMF and ORIF on pulmonary function (PF) in patients with mandibular fractures. Using a computer-generated simple randomization protocol, 40 eligible participants were allocated to MMF and ORIF treatment groups. PF tests were done preoperatively and at 24hours, 1, 6, and 7 weeks postoperative in all participants in both groups, using a portable office spirometer (Spirobank G). Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, and peak expiratory flow rate (PEFR) were determined. At 6 weeks postoperative, PF tests were performed after the release of MMF. PF tests in the MMF and ORIF groups were similar preoperatively. At 24hours postoperative, FEV1/FVC was significantly lower in the MMF group than in the ORIF group (p<0.001). Values of FEV1 (p=0.022), FEV1/FVC (p=0.001) and PEFR (p<0.001) were significantly lower in the MMF group than in the ORIF group at 1 week postoperative. While MMF negatively impacted on PF, ORIF had no adverse effect on PF.

Fasakin, O, Oyedotun K, Kebede M, Rohwer M, Roux L, Mathe M, Eleruja M, Ajayi E, Manyala N.  2020.  Preparation and physico-chemical investigation of anatase TiO2 nanotubes for a stable anode of lithium-ion battery, 2020/02/01. 6 Abstract

Ab-initio, anatase titanium dioxide (TiO2) nanotubes were prepared from pristine anatase titanium dioxide (TiO2) nanoparticles via a low temperature modified stirring-hydrothermal technique. Scanning electron microscope (SEM) characterization of the as-synthesized sample depicted uniformly distributed one-dimensional nanotubular morphology, with an average length, thickness and diameter of ∼ 4μm, 17 nm and 20 nm, respectively. N2 physisorption of the sample revealed two distinct peaks at mesopore and macropore scales of 3 nm and 100 nm, respectively. The specific surface area of the materials was observed to have increased from 8 m² g⁻¹ for the pristine to 62 m² g⁻¹ for the nanotubes. X-ray diffraction analysis indicated a tetragonal symmetry for the anatase TiO2nanotubes sample, which is similar to those reported in the literature. Core levels and elemental analyses showed the presence of titanium and oxygen in good proportion. Electrochemical performances of the TiO2nanotubes electrode offered good cyclic stability, good rate capability and a fairly large capacity of 160 mA h g⁻¹ at a specific current of 36 mA g⁻¹.

Famurewa, B, Oginni F, Aregbesola S, Erhabor G.  2020.  Pulmonary functions of patients with isolated mandibular fractures: A preliminary report, 2020/02/01. 46:36. Abstract

Objectives:The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients.
Materials and methods:
This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEFR), and ratio of FEV1 to FVC (FEV1/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern.
Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17-63 years). The mean FVC, FEV1, FEV1/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns.
Isolated mandibular fractures presented with abnormal pulmonary function pattern.

Movement Disorders. 35(8) Abstract

Background: Clinical disease registries are useful for quality improvement in care, benchmarking standards, and facilitating research. Collaborative networks established thence can enhance national and international studies by generating more robust samples and credible data and promote knowledge sharing and capacity building. This report describes the methodology, baseline data, and prospects of the Nigeria Parkinson Disease Registry. Methods: This national registry was established in November 2016. Ethics approval was obtained for all sites. Basic anonymized data for consecutive cases fulfilling the United Kingdom Parkinson's Disease Brain Bank criteria (except the exclusion criterion of affected family members) are registered by participating neurologists via a secure registry website ( using a minimal common data capture format. Results: The registry had captured 578 participants from 5 of 6 geopolitical zones in Nigeria by July 2019 (72.5% men). Mean age at onset was 60.3 ± 10.7 years; median disease duration (interquartile range) was 36 months (18–60.5 months). Young-onset disease (<50 years) represented 15.2%. A family history was documented in 4.5% and 7.8% with age at onset <50 and ≥ 50, respectively. The most frequent initial symptom was tremor (45.3%). At inclusion, 93.4% were on treatment (54.5% on levodopa monotherapy). Per-capita direct cost for the registry was $3.37. Conclusions: This is the first published national Parkinson's disease registry in sub-Saharan Africa. The registry will serve as a platform for development of multipronged evidence-based policies and initiatives to improve quality of care of Parkinson's disease and research engagement in Nigeria. © 2020 International Parkinson and Movement Disorder Society.

Neurology. 94(10) Abstract

ObjectiveTo characterize risk factors for spontaneous intracerebral hemorrhage (sICH) occurrence and severity among West Africans.MethodsThe Stroke Investigative Research and Educational Network (SIREN) study is a multicenter case-control study involving 15 sites in Ghana and Nigeria. Patients were adults ≥18 years old with CT-confirmed sICH with age-, sex-, and ethnicity-matched stroke-free community controls. Standard instruments were used to assess vascular, lifestyle, and psychosocial factors. Factors associated with sICH and its severity were assessed using conditional logistic regression to estimate odds ratios (ORs) and population-attributable risks (PARs) with 95% confidence intervals (CIs) for factors.ResultsOf 2,944 adjudicated stroke cases, 854 were intracerebral hemorrhage (ICH). Mean age of patients with ICH was 54.7 ± 13.9 years, with a male preponderance (63.1%), and 77.3% were nonlobar. Etiologic subtypes of sICH included hypertension (80.9%), structural vascular anomalies (4.0%), cerebral amyloid angiopathy (0.7%), systemic illnesses (0.5%), medication-related (0.4%), and undetermined (13.7%). Eight factors independently associated with sICH occurrence by decreasing order of PAR with their adjusted OR (95% CI) were hypertension, 66.63 (20.78-213.72); dyslipidemia, 2.95 (1.84-4.74); meat consumption, 1.55 (1.01-2.38); family history of CVD, 2.22 (1.41-3.50); nonconsumption of green vegetables, 3.61 (2.07-6.31); diabetes mellitus, 2.11 (1.29-3.46); stress, 1.68 (1.03-2.77); and current tobacco use, 14.27 (2.09-97.47). Factors associated with severe sICH using an NIH Stroke Scale score >15 with adjusted OR (95% CI) were nonconsumption of leafy green vegetables, 2.03 (1.43-2.88); systolic blood pressure for each mm Hg rise, 1.01 (1.00-1.01); presence of midline shift, 1.54 (1.11-2.13); lobar ICH, 1.72 (1.16-2.55); and supratentorial bleeds, 2.17 (1.06-4.46).ConclusionsPopulation-level control of the dominant factors will substantially mitigate the burden of sICH in West Africa.
