Studentsā Perception, Attitude and Experience as Factors Influencing Learning of Information Literacy Skills in Public Universities in Ogun State, Nigeria
In research and learning, information literacy is a necessary skill for both the students and the researchers to recognise when information is needed and have the ability to locate, evaluate, and use effectively the needed information.Ā This study focuses on information literacy within the context of these associated variables perception, attitude and experience. Data were collected through self-constructed questionnaire with Cronbatchās Alpha reliability coefficient of 0.7812. A spectrum of 3000 students from three universities constituted the sample. Three factors namely perception, attitude, and experience for which mean scores, alpha coefficients and correlations were calculated. One-sample t-test, independent samples t-test and one-way ANOVA were employed for significance and variance analysis. The study established the fact that studentsā perception, studentsā attitude and studentā experience are significantly related to information literacy skills. The results of this study should be utilized in providing guidelines for designing the new information literacy skills programme. Students regard information literacy as a valuable skill, and believe that a certain level of information literacy skill should be attained. More work must be done to define what constitutes information literacy skills and universities are advised to embark on programme on information literacy initiatives to fully satisfy their students.

Quality of sleep in an HIV population on antiretroviral therapy at an urban tertiary centre in Lagos, Nigeria
Aim. To determine the prevalence of sleep disturbance and its associated characteristics in HIV-positive outpatients on HAART using the PSQI. Methods. Using a cross-sectional design, 300 patients attending the outpatient HIV/AIDS clinic at the Lagos State University Teaching Hospital were recruited. Baseline data obtained included the participantsā demographic data, educational qualification, and marital status. Their treatment history, including duration since HIV diagnosis, the most recent CD4 cell count, and current antiretroviral therapies, was obtained from their case records. Each participant completed the PSQI questionnaire and those with scores ā„5 were diagnosed with poor sleep quality. Results. The participants were made up of 70.7% females and 29.3% males. Their ages ranged between 18 and 74 years with a mean of 38.9 Ā± 10.3 years. According to the PSQI, 59.3% reported poor sleep quality. The mean score of those with poor quality sleep (9.2 Ā± 3.3) was comparable to that of those with good quality sleep (1.26 Ā± 1.4). \u1d443 < 0.001. Significant differences were observed in all the individual components of the PSQI (\u1d443 < 0.001). On multivariate analyses, the independent associations with sleep quality were the duration since HIV diagnosis (\u1d443 = 0.29), efavirenz based regimen (\u1d443 < 0.001), and lower CD4 cell count (\u1d443 < 0.001). Conclusions. Sleep disturbances are quite common in the HIV population even in the era of HAART. Early recognition via routine assessment and effective treatments could prevent the resultant complications and improve quality of life
Chest X-ray findings in HIV- infected Highly Active Antiretroviral Treatment (HAART) - naĆÆve patients
Introduction: Patients with human immunodeficiency virus (HIV) infection frequently present with a wide spectrum of pulmonary and cardiaccomplications from the virus, opportunistic infections and neoplasms that may be associated with a high mortality rate. Diseases of the respiratorytract account for about half of deaths from AIDS, while cardiac diseases account for more than a quarter of deaths from AIDS. This study aimed atdetermining the prevalence of pulmonary and cardiac diseases using a chest radiograph in HAART-naĆÆve HIV-infected patients. Methods: Thisstudy was conducted at Lagos State University Teaching Hospital (LASUTH) HIV clinic between September 2010 and August 2011 amongst allregistered HAART-naĆÆve HIV/AIDS patients. Patients had posterior-anterior chest radiographs done in full inspiration. Participants were asked andaided to fill the structured questionnaires to obtain demographic data. Results: Out of a total of one hundred and two recruited for the study, 54 (52.94%) had a normal chest radiograph, while 48 (47.06%) had abnormal chest radiograph .The abnormal findings included, 27.45% who hadbronchopneumonia, 6.86% cardiomegaly, 5.88% pulmonary tuberculosis, 5.88% radiological features of congestive cardiac failure, and 0.98%bronchitis. Conclusion: It appears that more than half of HAARTānaĆÆve HIV-infected patients have normal chest radiographs. Bronchopneumonia(27.5%) is the commonest pulmonary abnormality associated with HIV infection, while the prevalence of pulmonary tuberculosis is 5.88%.Key words: Chest X-ray, HIV-infected, HAART-naĆÆve
Comparison of the Minimental State Examination Scale and the International HIV Dementia Scale in Assessing Cognitive Function in Nigerian HIV Patients on Antiretroviral Therapy
Introduction. HIV-associated neurocognitive disorder (HAND) remains common despite the availability of antiretroviral therapy. Routine screening will improve early detections. Objective. To compare the performance of the minimental state examination (MMSE) and international HIV dementia scale (IHDS) in assessing neurocognitive function in HIV/AIDS patients on antiretroviral therapy. Methods. A case-control study of 208 HIV-positive and 121 HIV-negative individuals. Baseline demographic data were documented and cognitive function assessed using the two instruments. CD4 cell counts were recorded. Results. Cases comprised 137 females and 71 males. Controls were 86 females and 35 males. Mean MMSE score of cases was 27.7 Ā± 1.8 compared to 27.8 Ā± 1.3 in controls (P = 0.54). Mean IHDS score in cases was 8.36 Ā± 3.1 compared to 10.7 Ā± 0.9 in controls (P < 0.001). Using the MMSE scale, 6 cases but no controls had HAND (P = 0.09). Using the IHDS, 113 (54.3%) had HAND compared with 10 (8.3%) controls (P < 0.0001). Using IHDS, 56.5% cases with CD4 count >ā200 had HAND compared with 92.5% with CD4 count <ā200 (P < 0.001). Conclusion. These findings indicate that the IHDS detects higher rates of HAND and may identify HIV/AIDS patients who require further cognitive assessment using more robust assessment batteries
The Kikuchi-Fujimoto Disease in Nigeria: A Case Report and Literature Review
The Kikuchi-Fujimoto is a rare, self-limiting disease, which is characterized by regional lymphadenopathy. It occurs worldwide with a higher prevalence among Asians and women below the age of forty years. We present 41-year-old Nigerian woman who was investigated extensively for unilateral left cervical lymphadenopathy. She was eventually diagnosed as having the Kikuchi-Fujimoto disease and was managed conservatively thereafter. We describe a case report and review of literature for better awareness of the disease amongst medical practitioners and pathologists in Africa
Prevalence of significant bacteriuria among symptomatic and asymptomatic homozygous sickle cell disease patients in a tertiary hospital in Lagos, Nigeria
Background: Patients with sickle cell disease have an amplified vulnerability to urinary tract infection, because of abnormally dilute and alkaline urine, which favors bacterial proliferation. This is due to altered blood flow in the renal vasculature, which causes papillary necrosis and loss of urinary concentrating and acidifying ability of the nephrons. Asymptomatic bacteriuria is common, but the prevalence in populations varies widely with age, gender, sexual activity and the presence of genitourinary abnormalities. The aim of this study was to determine the prevalence of significant bacteriuria in symptomatic and asymptomatic sickle cell patients in Lagos.Materials and Methods: This was a crossāsectional study of patients attending the sickle cell clinics of Lagos State University Teaching Hospital, Ikeja. Single voided aseptically collected midāstream urine was obtained from each patient and all samples processed immediately, were sent for urinalysis and culture. Isolates were considered significant if there were ā„105 colony forming units per milliliter (CFU/ml) with two or less isolates, doubtful significance if ā¤105 CFU/ml. Significant isolates were selected for identification. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 16.0 (SPSS, Inc., Chicago, Ill).Results: A total of 100 consenting participants were recruited into the study. The mean age was: 23.42 Ā± 8.31 years and a range of 14ā50 years. Only 9% (9/100) had significant bacteriuria while 44.4% (4/9) participants who had significant bacteriuria were asymptomatic. Escherichia coli was isolated in 66.6% (6/9) participants who had significant bacteriuria while Klebsiella oxytoca, Klebsiella pneumonia and Staphylococcus aureus (11.11%) was isolated in each of the remaining three participants.Conclusions: Significant bacteriuria is found in only oneātenth of sickle cell patients, nearly half of the participants who had significant growth had asymptomatic bacteriuria.Key words: Asymptomatic bacteriuria, prevalence, screening, sickle cell disease patients, significant bacteriuri
Leucine rich repeat kinase 2 (LRRK2) GLY2019SER mutation is absent in a second cohort of Nigerian Africans with Parkinson disease
To date the LRRK2 p.G2019S mutation remains the most common genetic cause of Parkinson disease (PD) worldwide. It accounts for up to 6% of familial and approximately 1.5% of sporadic cases. LRRK2 has a kinase enzymatic domain which provides an attractive potential target for drug therapies and LRRK2 kinase inhibitors are in development. Prevalence of the p.G2019S has a variable ethnic and geographic distribution, the highest reported among Ashkenazi Jews (30% in patients with familial PD, 14% in sporadic PD, 2.0% in controls) and North African Berbers (37% in patients with familial PD, 41% in sporadic PD, and 1% in controls). Little is known about the frequency of the LRRK2 p.G2019S among populations in sub-Saharan Africa. Our group and others previously reported that the p.G2019S is absent in a small cohort of Nigerian PD patients and controls. Here we used Kompetitive Allele Specific PCR (KASP) assay to screen for the p.G2019S in a larger cohort of Black African PD patients (n = 126) and healthy controls (n = 54) from Nigeria. Our analysis confirmed that all patients and controls are negative for the p.G2019S mutation. This report provides further evidence that the LRRK2 p.G2019S is not implicated in PD in black populations from Nigeria and support the notion that p.G2019S mutation originated after the early human dispersal from sub-Saharan Africa. Further studies using larger cohorts and advance sequencing technology are required to underpin the genetic causes of PD in this region
Clinical profile of parkinsonism and Parkinson's disease in Lagos, Southwestern Nigeria
<p>Abstract</p> <p>Background</p> <p>Current data on the pattern of parkinsonism and Parkinson's disease in Nigerians are sparse.</p> <p>This database was designed to document the clinical profile of PD in Nigerians, and compare this to prior observations.</p> <p>Methods</p> <p>A database of patients presenting to the Neurology out-patients clinic of the Lagos University Teaching Hospital was established in October 1996. Demographic and clinical data at presentation (disease stage using Hoehn and Yahr scale; 'off' state severity on the Unified Parkinson's disease Rating Scale) were documented for patients diagnosed with parkinsonism between October 1996 and December 2006. Cases were classified as Parkinson's disease or secondary parkinsonism (in the presence of criteria suggestive of a secondary aetiology).</p> <p>Results</p> <p>The hospital frequency of parkinsonism (over a 2-year period, and relative to other neurologic disorders) was 1.47% (i.e. 20/1360). Of the 124 patients with parkinsonism, 98 (79.0%) had PD, while 26 (21.0%) had secondary parkinsonism. Mean age (SD) at onset of PD (61.5 (10.0) years) was slightly higher than for secondary parkinsonism (57.5 (14.0) years) (P = 0.10). There was a male preponderance in PD (3.3 to 1) and secondary parkinsonism (2.7 to 1), while a positive family history of parkinsonism was present in only 1.02% (1/98) of PD. There was a modestly significant difference in age at onset (SD) of PD in men (60.3 (10.4)) compared to women (65.2 (7.9)) (T = 2.08; P = 0.04). The frequency of young onset PD (ā¤ 50 years) was 16.3% (16/98). The mean time interval from onset of motor symptoms to diagnosis of PD was 24.6 Ā± 26.1 months with majority presenting at a median 12 months from onset. On the H&Y scale, severity of PD at presentation was a median 2.0 (range 1 to 4). PD disease subtype was tremor-dominant in 31 (31.6%), mixed 54 (55.1%) and akinetic-rigid 14 (14.3%). Hypertension was present as a co-morbidity in 20 (20.4%), and diabetes in 6 (6.12%).</p> <p>Conclusions</p> <p>The clinical profile of PD in Nigerians is similar to that in other populations, but is characterized by delayed presentation as has been reported in other developing countries. Young-onset disease occurs but may be less commonly encountered, and frequency of a positive family history is lower than in western populations.</p
APOE E4 is associated with impaired self-declared cognition but not disease risk or age of onset in Nigerians with Parkinson's disease
The relationship between APOE polymorphisms and Parkinson's disease (PD) in black Africans has not been previously investigated. We evaluated the association between APOE polymorphic variability and self-declared cognition in 1100 Nigerians with PD and 1097 age-matched healthy controls. Cognition in PD was assessed using the single item cognition question (item 1.1) of the MDS-UPDRS. APOE genotype and allele frequencies did not differ between PD and controls (pā>ā0.05). No allelic or genotypic association was observed between APOE and age at onset of PD. In PD, APOE Īµ4/Īµ4 conferred a two-fold risk of cognitive impairment compared to one or no Īµ4 (HR: 2.09 (95% CI: 1.13-3.89; pā=ā0.02)), while APOE Īµ2 was associated with modest protection against cognitive impairment (HR: 0.41 (95% CI 0.19-0.99, pā=ā0.02)). Of 773 PD with motor phenotype and APOE characterized, tremor-dominant (TD) phenotype predominated significantly in Īµ2 carriers (87/135, 64.4%) compared to 22.2% in persons with postural instability/gait difficulty (PIGD) (30/135) and 13.3% in indeterminate (ID) (18/135, 13.3%) (pā=ā0.037). Although the frequency of the TD phenotype was highest in homozygous Īµ2 carriers (85.7%), the distribution of motor phenotypes across the six genotypes did not differ significantly (pā=ā0.18). Altogether, our findings support previous studies in other ethnicities, implying a role for APOE Īµ4 and Īµ2 as risk and protective factors, respectively, for cognitive impairment in PD
