A Comparison of the Semi Analytical and Numerical Method in Solving the Problem of Magnetohydrodynamics Flow of a Third Grade Fluid between Two Parallel Plates

The main purpose of this study is to compare a semi-analytical method and numerical method namely the homotopy perturbation method (HPM) and finite difference method (FDM) respectively. These methods were employed for solving the nonlinear problem of the magnetohydrodynamic (MHD) couette flow of third-grade fluid between the two parallel plates. The comparison was made between a solution of HPM and FDM against a solution obtained from regular perturbation and the results are tabulated. From a computational viewpoint, it is revealed that the HPM is more reliable and efficient than FDM. Also, the results show that the FDM requires slightly more computational effort than the HPM, although the HPM yields more accurate results than the FDM. &nbsp

Students’ 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.  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 Cronbatch’s 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 students’ perception, students’ attitude and student’ 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.

Factors associated with hospitalisation among people with Parkinson's disease – A systematic review and meta-analysis

INTRODUCTION: Parkinson's disease (PD) is associated with an increased risk of admission to hospital, however data on the main reasons for admission is lacking. Our objective was to determine the pooled prevalence of the most common factors leading to admissions among people with Parkinson's disease. METHODOLOGY: MA systematic literature search was conducted in 11 electronic databases. We included all studies providing reasons for admissions among PD patients without restrictions to diagnostic criteria of PD, language or year of study. In the included studies, methodological quality, publication bias and heterogeneity were assessed. Meta-analysis was performed using random-effects models to calculate the pooled estimates of the identified top factors that lead to admission among people with PD. RESULTS: A total of 7283 studies were identified of which nine studies including 7162 people with PD were included in this review. There was a high degree of heterogeneity between studies regarding reasons for hospitalisation. The pooled prevalence of the topmost reasons for hospitalisation among people with PD was 22%(95%CI 16.0%-30.0%) for infections (mainly urinary tract infections and pneumonia); 19%(95%CI 13.0%-27.0%) for worsening motor manifestations of PD; 18%(95%CI 14.0%-21.0%) for falls/fractures; 13%(95%CI 9.0%-18%) for cardiovascular co-morbidities; 8%(95%CI 4.0%-13.0%) for neuropsychiatric and 7%(95%CI 4.0%-11.0%) gastrointestinal complications. CONCLUSION: The main reasons for hospitalisation among people with PD are infections, worsening motor features, falls/fractures, cardiovascular co-morbidities, neuropsychiatric and gastrointestinal complications. Further research is needed in targeting and implementing preventative strategies

Rate of Hospitalizations and Underlying Reasons Among People with Parkinson's Disease: Population-Based Cohort Study in UK Primary Care

BACKGROUND: Hospitalization in Parkinson's disease (PD) is associated with reduced quality of life, caregiver burden and high costs. However, no large-scale studies of rate and causes of hospitalizations in patients with PD have been published. OBJECTIVE: To investigate the rate and reasons for hospitalization and factors associated with hospitalization among people with PD compared to the general population. METHODS: We examined rate and causes of admission in PD patients and matched controls in The Health Improvement Network from 2006 to 2016. Multivariable Poisson regression was used to explore the effects of age, gender, social deprivation, urbanicity and practice geographic location on hospitalization. RESULTS: In longitudinal data from 9,998 newly diagnosed individuals with PD and 55,554 controls without PD aged≥50years, 39%of PD patients and 28%of controls were hospitalised over a median follow-up 5.1years. The adjusted incidence rate ratio(IRR) of hospitalization in PD compared to controls was 1.33(95%CI:1.29-1.37) and rose with increased follow-up duration. Hospitalization rate was overall higher in the older age groups, but the adjusted IRR of hospitalization compared to controls was highest in the youngest age group. PD patients were more often admitted with falls/fractures, infections, gastrointestinal complications, PD, dementia, psychosis/hallucinations, postural hypotension, electrolyte disturbances, stroke and surgical procedures and slightly less often due to hypertension. CONCLUSION: People with PD have an increased hospitalization rate compared to controls, particularly in the younger age groups, and it increases with longer disease duration. The complications of motor and non-motor features of PD are amongst the main reasons for admission, some of which could be managed preventatively to avoid admissions

Mortality of People with Parkinson's Disease in a Large UK-Based Cohort Study: Time Trends and Relationship to Disease Duration

BACKGROUND: Parkinson's disease (PD) is associated with increased mortality, but little is known about changes over time, and relationship to disease progression. OBJECTIVES: To explore how PD mortality rates have changed over time and their relationship to disease duration and demographics using a large population-based cohort in the UK. METHODS: We included individuals aged 50+ years with a first recording of PD diagnosis and at least two prescriptions of any antiparkinsonian drug actively registered within a general practice from 2006 to 2016 and up to six frequency-matched controls from The Health Improvement Network (THIN) database. We estimated adjusted mortality rates using multivariable Poisson regression. RESULTS: A total of 10,104 people with a diagnosis of PD and 55,664 people without PD were included. Overall, PD was associated with slightly increased mortality compared to non-PD controls (adjusted mortality rate ratio: 1.14; 95% CI: 1.03 to 1.19). Adjusted mortality rates per 1000 person-years at risk for people with PD approximately doubled in the 5 years following diagnosis from 43 (95% CI: 38 to 48) to 75 (95% CI: 64 to 85). Following adjustments for age, gender, and time since diagnosis, mortality rates between 2007 and 2016 declined more slowly for people with PD (2% per year; 95% CI: 0%–4%) compared to people without PD (5% per year; 95% CI: 3%–6%). CONCLUSIONS: Whilst mortality in PD is only slightly increased overall, it gradually increases with advancing disease. There has been a decline in mortality in PD over time, but this decrease was less pronounced than that in the general population. © 2021 The Authors.

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
