Variation of Soil PH Using Circularly Polarized Light

The use of  a commercial circular polarizer to produce polarized light from a 85W conventional source and its influence on the pH of sandy loam soils is presented. The role of soil pH in the determination of plant nutrient requirements has made its monitoring important for plant growth and development. The study was designed to determine the effectiveness of using circularly polarized light to amend the level of soil acidity and alkalinity. Samples of acidic and alkaline sandy loam soils were exposed to a collimated beam of the circularly polarized and the pH and temperature measured at 1 - hour intervals for 8 hours in a dark room. The control was soil samples exposed to unpolarized light from another 85W conventional source. All the samples were replicated three times. The results show that circularly polarized light has the ability to significantly increase the pH of sandy loam acidic soil while it had no appreciable effect on the alkaline soil . This could provide an alternate non - chemical means of managing highly acidic sandy loam soils. Key words: Soil pH,  Circular Polarizatio

Allelopathic Effect of Topsoil Extract From Tectona grandis L. Plantation on the Germination of Lycopersicum esculentum

The use of topsoil extracts transferred from Tectona grandis L. plantation to explore similar effects and use of the leaf, bark and root extracts on germination and growth of Lycopersicum esculentum is presented. The study was designed to determine the effect of variation of masses of topsoil extracts from teak plantation on the germination and growth response of tomato seeds planted on another soil whose physico - chemical analysis indicate that it can support plant growth. The topsoil extracts were collected in 5kg, 5.5kg, 6kg and 6.5kg packs and respectively spread on 4 mini - plots each with 3 replications and containing 50 planted tomato seeds. The control was the mini - plot without any topsoil extracts. The results showed that the topsoil extracts were able to suppress the germination of the tomato seeds and the effect increased with the mass used. There was a significantly progressive decrease in the mean tall lengths of the seedlings with mass of topsoil indicating a growth inhibition. However, the effect was not very much pronounced in the comparison of the mean values of the short lengths of the seedlings. Key words: Allelopathy,  topsoil extracts, germinatio

Small - Scale Surface Mining in Tarkwa - Nsuaem Municipality in Western Ghana and its Effect on Soil Physical Properties

Small - scale surface mining in Tarkwa - Nsuaem municipality in western Ghana and its effect on soil physical properties is presented in this study. The rising rate of land degradation by the small - scale surface miners in the study area has created a situation in which farmlands are becoming scarce and farmers are left with no choice than to use mined - out lands. The study set out to measure the physical properties of soil from mined - out lands to determine their suitability for use for agricultural purposes. One set of samples comprising soil from mined and unmined sites were randomly collected using a cylindrical metal core of known volume. After recording their wet weights, the samples were then oven dried at 105°C for 24 hours after which their dry weights were also recorded. The bulk density, porosity, solid space, mass wetness and void ratio were then calculated. The procedure was repeated for three other sites in the study area. The results showed that the mined soil, in its current state, was unsuitable for use by farmers for agricultural purposes because it was compacted, less porous, susceptible to erosion, dry and could barely support plant life. It was recommended that practices that maintain or increase soil organic matter which leads to high pore space and low bulk density be adopted to restore the mined - out lands to their natural state. Keywords: Bulk density, Porosity, Pore space, Mass wetness, Void rati

DIGITAL TRANSFORMATION EDUCATION: CHALLENGES, EFFECTIVENESS, AND PERCEPTIONS OF COMPUTER-ASSISTED INSTRUCTION APPLICATION IN PHYSICS CLASSROOM

Digital Transformation Education has received greater attention in teaching and learning, however, there is a scarcity of studies on the challenges, effectiveness, and perceptions of Computer-Assisted Instruction (CAI), especially in the Colleges of Education (CoE). In addressing these, the study used the mixed method research design using 12 Physics tutors and 254 Physics students from 3 CoE purposively selected from the Sekyere South District and the Mampong Municipality. Interviews and questionnaires were used for data collection and data analysis was done using Statistical Package for Social Sciences ¬(IBM SPSS), version 26.1, employing descriptive statistics and thematic analysis. The results indicated that Physics tutors generally face a high level of challenges, with inadequate technological resources and limited financial support posing the greatest hindrances. In response, tutors employed various strategies including personal investment in internet bundles and advocacy for institutional intervention. It was again found that both quantitative and qualitative findings converged after merging and that the qualitative findings agreed with the quantitative findings. It was concluded that tutors of Physics in the CoE in the Mampong Municipality and the Sekyere South District encounter challenges during their integration of CAI in their Physics lessons. However, since students of Physics in the CoE perceive the use of CAI as very positive to their academic lives, it was recommended that using CAI for teaching and learning Physics in the colleges of education should be fortified.  Article visualizations

Implementation of a medicine management plan (MMP) to reduce medication-related harm (MRH) in older people post-hospital discharge: a randomised controlled trial

Background Medication-related harm (MRH) is an escalating global challenge especially among older adults. The period following hospital discharge carries high-risk for MRH due to medication discrepancies, limited patient/carer education and support, and poor communication between hospital and community professionals. Discharge Medical Service (DMS), a newly introduced NHS scheme, aims to reduce post-discharge MRH through an electronic communication between hospital and community pharmacists. Our study team has previously developed a risk-prediction tool (RPT) for MRH in the 8-weeks period post discharge from a UK hospital cohort of 1280 patients. Method Using a randomized control trial design, 682 older adults ≥ 65years due to be discharged from hospital will be recruited from 4 sites. Participants will be randomized to an intervention arm (individualised medicine management plan (MMP) plus DMS) or a control arm (DMS only) using a 1:1 ratio stratification. Baseline data will include patients’ clinical and social demographics, and admission and discharge medications. At 8-weeks post-discharge, a telephone interview and review of GP records by the study pharmacist will verify MRH in both arms. An economic and process evaluation will assess the cost and acceptability of the study methods. Data Analysis Univariate analysis will be done for baseline variables comparing the intervention and control arms. A multivariate logistic regression will be done incorporating these variables. Economic evaluation will compare the cost-of-service use among the study arms and modelled to provide national estimates. Qualitative data from focus-group interviews will explore practitioners’ understanding, and acceptance of the MMP, DMS and the RPT. Conclusion This study will inform the use of an objective, validated RPT for MRH among older adults after hospital discharge, and provide a clinical, economic, and service evaluation of a specific medicines management plan alongside the DMS in the National Health Service (UK)

Prevalence of non-communicable diseases and its risk factors among Ijegun-Isheri Osun residents in Lagos State, Nigeria: a community based cross-sectional study.

BACKGROUND: The rapid epidemiologic transition of diseases has adverse implications for low-and middle-income countries (LMICs) like Nigeria due to their limited healthcare, weaker health systems and the westernization of lifestyle. There is a need to evaluate the enormity or otherwise of non-communicable diseases (NCDs) burden in such low resource settings. We performed this survey to determine the prevalence of NCDs and its risk factors among the Ijegun- Isheri Osun community residents of Lagos, Nigeria. METHODS: A community-based cross-sectional survey was performed on 215 respondents recruited consecutively during a population preventive health campaign. Prevalence of three NCDs (hypertension, diabetes and dyslipidaemia) were calculated. Associations between each of these NCDs and selected risk factors were determined using chi square test. Multivariable logistic regression was used to estimate the risk factors of each of the three NCDs. RESULTS: The prevalence of hypertension was 35.3% (95% CI 29.0-42.1), diabetes 4.6% (95% CI 2.2-8.4) and dyslipidaemia 47.1% (95% CI 41.1-54.8). Among the NCD risk factors, the prevalence of smoking was 41.3% (95% CI 34.2-48.6), alcohol consumption 72.5% (95% CI 65.5-78.7), and physical activity 52.9 (95% CI 45.5-60.2). The independent significant predictors of hypertension were age ≥ 60 years (aOR 4.56; 95% CI: 1.72-12.09) and dyslipidaemia (aOR 5.01; 95% CI: 2.26-11.13). Age ≥ 60 years (aOR 8.83; 95% CI: 1.88-41.55) was an independent predictor of diabetes. Age ≥ 60 years (aOR 29.32; 95% CI: 4.78-179.84), being employed (aOR 11.12; 95% CI: 3.10-39.92), smoking (aOR 2.34; 95% CI: 1.03-5.33) and physical activity (aOR 0.34; 95% CI: 0.15-0.76) were independent predictors of having dyslipidaemia. CONCLUSIONS: The prevalence of hypertension, diabetes and dyslipidaemia and their associated risk factors are high among the respondents of Ijegun-Isheri Osun community of Lagos state, Nigeria. This highlights the need for further implementation research and policy directions to tackle NCD burden in urban communities in Nigeria. These strategies must be community specific, prioritizing the various risk factors and addressing them accordingly

A typical Kawasaki syndrome in COVID-19 infection: a case report of a multisystem inflammatory syndrome in a child (MIS-C)

The emergence of COVID-19 by a novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) in 2019 has seen evolving data reporting infrequent infection in children and mostly mild disease for children who contract the infection. A severe form of COVID-19 in children recently reported in Europe and North America describes a multisystem inflammation syndrome in children (MIS-C), presenting as toxic-shock-like and Kawasaki-like syndromes. Data on MIS-C in Africa is being documented with recent reports from South Africa and Nigeria in black children, but information on MIS-C in Ghana is yet to be characterized. We report the first case of multisystem inflammatory syndrome in a child who tested PCR positive to SARS-CoV2 in a tertiary hospital in Ghana. The case describes a 10-year-old boy who reported Kawasaki-like syndrome without shock but with moderate respiratory distress requiring supportive acute care without the need for intensive care

FRailty and Arterial stiffness – the role of oXidative stress and Inflammation (FRAXI study)

Objective: There is an association between frailty and arterial stiffness. However, arterial stiffness does not uniformly correlate with the spectrum of frailty states. Both oxidative stress and inflammaging contribute to vascular ageing. There are no human studies exploring links between arterial stiffness, oxidative stress, inflammaging and frailty. Our objective is to investigate arterial stiffness and inflammaging as predictors of frailty states. Methods: An observational longitudinal cohort study will be used to examine the association between arterial stiffness, oxidative stress and inflammation in 50 older adults (⩾70 years) with clinical frailty scores (CFS) ⩽6 over 6 months. All study measurements will be taken at baseline. Frailty assessment will include hand-grip strength, timed-up and go test, mini-mental state examination, geriatric depression scale and sarcopenia using body composition measurements with Tanita®. Arterial stiffness measurements will include carotid-femoral pulse wave velocity (cfPWV) and carotid-radial pulse wave velocity (crPWV) using Complior (Alam Medical, France). CAVI device will measure Cardio-ankle vascular index and ankle brachial index (ABI). Oxidative stress blood markers nitrotyrosine (NT) and 8-hydroxy-2’-deoxyguanosin (8-oxo-dG) and inflammation markers high-sensitive C-reactive protein (hs-CRP) and interlukin-6(IL-6) will be measured at baseline and 6 month along with lipid profile and glycated haemoglobin. Results (data analysis plan): Descriptive statistics for continuous data using means and standard deviations for normality distributed variables or medians and inter-quartile ranges for skewed variables will be used. Participants will be categorised into CFS 1-3, and CFS 4-6. Categorical data will use frequencies and comparison between groups. Change in frailty between the groups over 6 months will be compared using paired t-test. Simple linear regression will be done between frailty measures, arterial stiffness, inflammation and oxidative stress biomarkers. Significance will be at P < .05. Conclusion: This study data will inform a larger, multi-centre study exploring further the interplay between frailty, biomarkers and arterial stiffness parameters

Preeclampsia in Ghana: A study on the prevalence and risk factors of postpartum readmission in the Ashanti region

Background: Despite significant improvements in its management, preeclampsia continues to be one of the frequent causes of postpartum readmission. Increased awareness of the risk factors for postpartum readmission is required to reduce its incidence and related complications. This study determined the prevalence and associated risk factors for postpartum readmission among women with preexisting preeclampsia in a Ghanaian population. Methods: This hospital-based retrospective study was conducted at the obstetrics and gynaecology units of Komfo Anokye Teaching Hospital in Ghana. We reviewed the medical records including sociodemographic and obstetric characteristics of preeclampsia patients. Statistical analyses were performed using Statistical Package for Social Sciences Version 26.0 and GraphPad Prism version 8.0. p-Value \u3c0.05 was considered statistically significant. Results: A total of 208 preeclampsia patients were considered in this study. The rate of postpartum readmission for a hypertensive disorder among women with preeclampsia was 46%. After adjusting for multiple confounders in the multivariate logistic model, having a family history of hypertension [aOR = 3.512, 95% CI (1.669–7.394), p = 0.0028] was associated with increased odds for postpartum readmission. However, being nulliparous [aOR = 0.321, 95% CI (0.116–0.887), p = 0.0028] was independently associated with a reduced odd for postpartum readmission. Conclusion: The rates of postpartum readmission are significantly high among preeclampsia women. Our findings highlight the importance of continued efforts to improve the health outcomes of both mother and newborn, including heightened monitoring of at-risk patients in the Ghanaian population
