Students’ Perception Towards Solid Waste Management and Environmental Sustainability of Nnamdi Azikiwe University Campus, Awka

Nigeria’s rising population makes waste generation an inevitable endeavour. In the journey of national development, waste generation is static. With a population of over 170 million, Nigeria produces a staggering volume of solid waste, of which less than 20% is collected through a formal system. Waste generation on the Nnamdi Azikiwe University campus, Awka, has remained contentious as generated waste is neither categorised nor recycled for re-usage purposes. The survey research method was adopted for this research, with the questionnaire utilised as research instrument. This study included the entire population due to size manageability. Statistically, descriptive and inferential statistical analyses were fit for purpose and, hence, utilised. Findings revealed that biological processing of waste and environmental waste management education would result in the environmental sustainability of the Nnamdi Azikiwe University campus, Awka. This study recommends that the university management prioritise building a biological waste processing facility and champion the creation of environmental waste management education awareness for improved harmful waste generation and control.

Prevalence of Malaria Infection among Pregnant Women Attending Antenatal Clinic in Nnamdi Azikiwe University Teaching Hospital, Nnewi

Malaria is a major health problem affecting people in the tropics and sub-tropical regions of the world. This cross-sectional hospital-based study was carried out to determine the prevalence of malaria infection among pregnant women attending a tertiary hospital in Nnewi, Anambra State, Nigeria. A total of 100 venous blood samples were collected from pregnant women into EDTA tubes and examined using field-stained thick and thin films for identification of malaria parasites. Demographic information such as age, trimester and insecticide-treated nets usage was obtained using a structured questionnaire. Data was analyzed using Statistical Package for the Social Sciences version 22. The chi-square test was used to determine the difference among the variables studied and P≤ 0.05 were considered significant. Out of the 100 blood samples examined, 27 were infected and had an overall prevalence of 27%. Women within the age bracket of 31-35 years had the highest prevalence rate 11(36.7%) while no infection was recorded in the 41-45 years age group 0(0.0%). Pregnant women in their first trimester had the highest infection prevalence of 13(35.1%) while those in their third trimester had the least prevalence of 5(17.9%). In relation to ITN’s usage, pregnant women who don’t normally sleep under ITNs had the highest infection prevalence 23(31.5%) while those who usually sleep under ITNS had the least prevalence rate 4(14.8%). It is pertinent to periodically check the malaria infection status of pregnant women attending antenatal services. Prophylactic treatment should be routinely administered to avoid pregnancy complications due to malaria infection.

Implementing Cooperative Learning for Sustainable STEM Education in Nigeria: Preservice Science Teachers’ Knowledge and Beliefs

The study investigated preservice science teachers’ (PST) knowledge and beliefs about the implementation of cooperative learning for sustainable science, technology, engineering, and mathematics (STEM) education in Nigeria given that evidence shows that several Nigerian teachers are still unskilled in 21st-century pedagogies. The study sought to determine PSTs’ competencies for implementing cooperative learning in science classrooms, as informed by their knowledge and beliefs about the effectiveness of applying cooperative learning to teach science concepts. Four research questions guided the study. The design of the study is a descriptive survey involving the collection of quantitative data via questionnaires. This research design is appropriate for the present study as it sought to determine the knowledge and beliefs PSTs have about cooperative learning (CL). The study sample was drawn from all the PSTs in the federal tertiary institution (Nnamdi Azikiwe University, Awka) in Anambra State, Nigeria using the convenience sampling technique. The data for this study were collected electronically using an adapted version of Bouas (1993). The scale’s reliability was determined using the Cronbach alpha technique (α=.73). Percentage, weighted mean, and standard deviation, and one sample t-test were used to analyse the data collected in this study. The study’s findings showed that PSTs in Nigeria were both knowledgeable and held positive beliefs about cooperative learning pedagogy. Based on the study’s findings, implications for the study were discussed.

Improving struggling medical and nursing students’ subjective vitality, school engagement and academic performance through a peer mentorship intervention programme: an intervention protocol

BackgroundThe undergraduate medical training programme is demanding and rigorous. This underlines the importance of a peer mentorship strategy to improve the well-being, self-determination, school connectedness, and performance of struggling medical and nursing students. This study is aimed at identifying struggling medical and nursing students using two cumulative continuous assessment test (CAT) scores, assess their subjective vitality and school engagement and evaluate the impact of the peer mentorship intervention on them.MethodsThe study will adopt a mixed-methods approach and will be conducted in the medical colleges of Nnamdi Azikiwe University, Awka, Nigeria, and the University of Rwanda. Three instruments will be used: The subjective Vitality Scale (SVS), the University Student Engagement Inventory (USEI), and the academic records of the students before and after the commencement of the intervention programme. The consenting least-performing medical and nursing students identified by their low CAT scores (below 45%) in basic medical sciences will be selected for study in each institution. The outcome measures will include students’ CAT scores, subjective vitality, and school engagement scores. The data will be analysed both quantitatively and qualitatively. Thematic content analysis will be adopted in the analysis of the responses generated from the focus group discussion. The mean ± standard deviation or median and interquartile range statistic will be adopted for the quantitative data.DiscussionGiven the paucity of data on struggling medical and nursing students in Nigeria and Rwanda, this research was designed to help in exploring evidence-based interventions to improve and prevent poor subjective well-being of struggling students. The study is expected to fill these knowledge gaps. Trial registration: Pan African Clinical Trial registry, PACTR202405546896613, registration date: 27th May, 2024.

Ecological Assessment of Weed Species in Two Secondary Forests in Anambra State Nigeria

An ecological study was done on weed species in two secondary forests present in Nnamdi Azikiwe University, Awka Campus and Federal College of Education Umunze, Anambra State, Nigeria. Data was collected from the two study sites which were randomly divided for adequate coverage and proper representation. Species dominance, abundance and diversity of weed species were recorded. The result of the study showed that a total of 21 weed species were recorded in Plot 1 study area which is at Nnamdi Azikiwe University, Awka campus; Pennisetum purpureum had the highest species abundance in the study site, with a total frequency of 93 and Dominance index of 28.97. Pennisetum purpureum had a relative density of while Tridax procumbens was the second most abundant with a frequency of 40 and Dominance of 7.10. Rhynchospora corymbosa showed the least abundance with a frequency of 6. The result of Shannon Wiener index for weed species in Plot 1 study was 2.56 and this showed that there is high diversity of weed species in the study area. Meanwhile, the result of the study in Plot 2, which is at Federal College of Education, Umunze showed that a total of 18 weed species were recorded; Imperata cylindrica had the highest species abundance in the study site, with a total frequency of 87 and Dominance index of 27.43, while Cypertrus rotundus was the second most abundant with a frequency of 67 and Dominance index of 10.5. Acanthus Montana showed the least in abundance with a frequency of 6 and Dominance index of 1.02. The result of Shannon Wiener index for weed species in Plot 2 study was 2.47 and this also showed that there is high diversity of weed species in the study area. This result invariably indicates a great potential for utilization in conservation and ecological purposes.

Environmental Factors, Undergraduate Science Education Students’ Achievement, and Interest in Nigeria Universities: Implications for Funding

This study investigated the effects of environmental factors on the academic performance and interest of undergraduate scientific education students in Nigerian universities, as well as the funding implications. A descriptive survey research design was used in the study. The study included 270 final-year undergraduate students from the Department of Science Education at two Nigerian universities: Chukwuemeka Odumegwu Ojukwu University, Igbariam, and Nnamdi Azikiwe University, Awka. Both universities are located in the sixth state of Anambra. The study used a sample of 161 students, 56 of whom were male and 105 of whom were female, that was drawn by chance sampling methods. Three experts verified the questionnaire, which was used as the data gathering tool. Using the Cronbach Alpha formula, the dependability of 0.90 was determined. The hypothesis was examined using t-test statistics at the 0.05 level of significance, and the research topic was addressed using mean and standard deviation. The study's conclusions showed that, while gender had no discernible impact on how science education students responded to the aforementioned environmental factors, socioeconomic background, good school infrastructure, extracurricular activities, class size, accommodations, attitudes of teachers and parents, appropriate teaching methods, and poor lighting in school buildings and hostels could all affect students' interest and achievement in science education at universities. Further strategies for enhancing the environmental elements that affect academic achievement and interest of science education students in universities include the government's and alumni's funding of science labs and infrastructure, fostering university competition, using appropriate teaching methods, and properly citing of schools.

THE IMPACT OF COLLABORATIVE CARE ON COST OF TREATMENT FOR THE MANAGEMENT OF HYPERTENSION- A SYSTEMATIC REVIEW

Introduction: For evaluation of the long term costs and benefits of physician-pharmacist collaboration associated with physician management for the treatment of essential hypertension. Around the world the major cause of death is hypertension. It is an incurable condition that requires proper therapeutic regimens for its life-long management. Due to this, hypertension therapy can be financially burdensome to the patient, and the rates of non-compliance are increased. Aims and Objectives: To observe the results of collaborative, clinical, and interventive approaches to hypertension management, on the cost-effectiveness of therapy, this study aimed to collect and compare cost information on hypertension management, mortality, and morbidity across different countries and cost groups. Using this information, future healthcare expenses can be better planned; for example, by initial emergency response or by changing the way money is distributed. This will lead to more high-pressure jobs. Therefore, it will be more costly to control blood pressure. Method: A systematic review was conducted using 6 major electronic databases that investigated the influence of collaborative care upon healthcare expenses in hypertensive patients and hypertension therapy costs, before and after the intervention of medical personnel, was observed. Conclusions: It was concluded that interventions provided by the collaboration of medical personnel, in the management of hypertension, made the therapy more cost-effective and hence the rate of patient compliance and adherence to the therapy were increased.

TREATMENT OUTCOMES IN PCOS (POLYCYSTIC OVARIAN SYNDROME)-RELATED INFERTILITY

Polycystic ovarian syndrome (PCOS) is one of the underdiagnosed endocrine disorders found to be prevalent among females in the reproductive age group. PCOS effects on an average 8-13% of reproductive aged women, globally. This condition is responsible for causing distress physiologically and psychologically paving the way for a poor quality of life. One of the devastating complications of PCOS is infertility. At present, there is no treatment for PCOS but could be managed by alternate options such as lifestyle modification to in-vitro fertilization. The primary objective of this review article is to analyze the outcomes of certain pharmacological treatment options such as clomiphene citrate which is a selective estrogen receptor modulator, Letrozole an aromatase inhibitor, and gonadotropins for PCOS-related infertility. Clomiphene citrate binds to estrogen receptors indirectly increasing the gonadotropins. Studies confirm a 35-40% successful outcome. Letrozole similarly increases gonadotropins by indirectly decreasing estrogen. A notable increase in the successful outcome was observed with both clomiphene citrate and letrozole, with almost near similar results. The pregnancy outcome was approximately 40% with clomiphene citrate, while letrozole showed 50%. Notably, more side effects were observed in the administration of clomiphene citrate compared to letrozole. Human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (FSHr), that are gonadotropins, were used as they are directly responsible for the maturation of follicles and ovulation itself. The use of gonadotropins increased the pregnancy rate outcome to 20 -30 %, albeit with the risk of multiple births. Furthermore, we have discussed why letrozole and clomiphene citrate are used as the primary therapy compared to gonadotropins.

Reproductive Analysis of Bryophyllum pinnatum Leaf extract against Cadmium Induced Testicular Damage

The purpose of this study is to explore if treatment with aqueous leaf extract of Bryophyllum pinnatum was effective in minimising cadmium induced testicular damage on the testes of male wistar rats. Twenty (20) mature male wistar rats was collected from Animal House of the Faculty of Basic medical Sciences, Nnamdi Azikiwe University, Awka. Four subgroups, each consisting of four rats, were created from them. Group I was the control group and was given unlimited access to food and water for a period of two weeks. Group II was given a two-week treatmet of B. pinnatum together with CdcT + lovv. Group III had B. pinnatum at a medium dosage together with Cdcl for a fortnight. For two weeks, group IV received a high dosage of B. pinnatum along with Cdcl. Upon completion of the final dosage, the rats were sedated, and a blood sample was taken from each one via ocular puncture using a micro capillary tube for biochemical analysis and an epididymis dissection for semen analysis. All particulate parameters were analysed according to standard protocols. The results indicated a significant (p<0.05) decrease in the rats’ final body weights in groups B and D in comparison to the control group. When the test groups’ testicular weight was compared to the control group, it dropped considerably (p<0.05). Comparing all test groups to control, there was a significant (p<0.05) decrease in both FSH and testosterone. When comparing the test groups to the control, there was a substantial (p<0.05) decrease in the motility of active sperm, but there was a significant (p<0.05) increase in the motility of sluggish and non-motile sperm. This study shown that Bryophyllum pinnatum leaf extract cannot reverse the reproductive harm caused by cadmium in rats.

Intimate partner violence among pregnant women in Anambra State, Nigeria: Prevalence, pattern, determinants and coping strategies

ABSTRACT Background: Intimate partner violence (IPV) has emerged as a global phenomenon, with pregnant women being particularly vulnerable, especially in developing countries. Despite its diverse manifestations and severe impacts, IPV is sometimes perceived as culturally acceptable or as a means of controlling women. Aims: This study aimed to assess the prevalence, patterns and determinants of IPV amongst pregnant women attending antenatal care (ANC) at a tertiary hospital in Anambra State, Nigeria. Materials and Methods: This cross-sectional survey enrolled 400 pregnant women receiving ANC at Nnamdi Azikiwe University Teaching Hospital, Nnewi, Anambra State. Data collection utilised semi-structured, self-administered questionnaires. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 26. Results: In this study we found a 21.8% prevalence of IPV. Psychological violence was the most common form, followed by sexual and physical violence at rates of 72.4%, 35.6%, and 32.2% respectively. Risk factors associated with IPV included low educational attainment, maternal unemployment, average monthly income of <50,000 naira, partner unemployment and substance abuse, increased maternal age, having family members choose their partner and marital conflicts. Various coping strategies were identified amongst victims, including help-seeking, spiritual recourse, substance abuse, retaliation and divorce. Alarmingly, 75.9% of the participants took no action when faced with IPV. Conclusion: This study underscores the prevalence of IPV among pregnant women, with approximately one in five reporting victimisation during pregnancy. Psychological, sexual, and physical forms of violence occurred in decreasing order of prevalence. We found that a range of factors, including individual and relationship-related factors, correlated with increased odds of IPV. Women who experience IPV adopt different strategies, including help-seeking, spiritual recourse, substance abuse, retaliation, divorce and in some cases, passivity.

Phytotoxic effect of Carica papaya extract on seed-borne fungus of African Yam Bean (Sphenostylis stenocarpa Hochst ex. A. Rich. Harms) seeds

Extracts of many higher plants have been reported to exhibit antifungal properties under laboratory experiments. This study was therefore carried out to investigate the effect of Carica papaya plant extracts on the African Yam Bean seed-borne pathogen. The seed health test of African Yam Bean was carried out using the blotter paper method. The experiment was conducted at the Plant Pathology Laboratory of the Department of Crop Science and Horticulture, Nnamdi Azikiwe University, Awka. Test of plant extract for inhibition of radial growth of seed-borne pathogen of African yam bean was studied under in vitro experiment at 0%, 50%, 75% and 100% concentrations with 0% as the control. The design was a Completely Randomized Design (CRD) with three replications. The test plant extracts of different concentrations were added into Petri dishes containing molten-sterilized Sabouraud Dextrose Agar (SDA) and swayed gently on the laboratory bench to allow an even mixture These were allowed to gel. Then nine millimeter discs of a seven-day pure culture of Aspergillus flavus were aseptically placed on the centre of the Petri dishes containing the SDA-extract mixture. Records on the radial inhibition effect of the test plant extract were kept for further analysis. Data on radial inhibition of fungus were subjected to Analysis of Variance (ANOVA). Results showed that Aspergillus niger, Aspergillus flavus and Aspergillus terreus were isolated from incubated African Yam Bean seeds. Carica papaya leaf extract used was very effective and the higher the concentrations of extract, the more effective in the inhibition of radial growth of the test fungus. It could therefore be recommended that farmers should always conduct viability tests on procured seeds before planting. Farmers should rather use plant extract such as the one used in this experiment in controlling seed-borne fungal pathogens of African Yam Bean seeds than synthetic fungicides.

Epidemiological trends and treatment abandonment of paediatric solid tumours in a nigerian tertiary hospital: a seven-year review (2016–2022)

BackgroundPaediatric solid tumours, both benign and malignant, present significant health challenges, particularly in Sub-Saharan Africa where comprehensive data is limited. This study aims to elucidate the prevalence, distribution, and treatment outcomes of paediatric solid neoplasms in a tertiary hospital in South-East Nigeria over a seven-year period.MethodsA retrospective cohort study was conducted at Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria. Clinical details and histological slides of confirmed cases from January 2016 to December 2022 were reviewed. Data extraction focused on socio-demographic variables and treatment outcomes, analysed using statistical methods.ResultsThe study included 293 children diagnosed with solid tumours (58.1% malignant, 41.9% benign), with a female predominance (61.8%). The median age at diagnosis was 12 years. Fibroadenoma was the most common benign tumour (61.8% of benign cases), while non-Hodgkin lymphoma was the predominant malignant tumour (18.2% of malignant cases). Treatment abandonment rates differed significantly between benign (13.8%) and malignant (51.2%) tumours. Significant associations were found between treatment outcomes and factors such as gender (p = 0.0001 for benign tumours), age category (p = 0.0001 for benign tumours), and specific diagnoses (p = 0.0001 for both benign and malignant tumours).ConclusionThis study underscores the substantial burden of paediatric solid tumours in South-East Nigeria and highlights the critical need for improved treatment adherence strategies, particularly for malignant cases. The findings emphasize the importance of tailored interventions based on tumour type, age, and gender. These insights can inform future research, policy formulation, and healthcare strategies aimed at enhancing the management and outcomes of paediatric solid neoplasms in resource-limited settings.

Possible alteration in serum ferritin level in malaria infected HIV seropositive individuals in Nauth, Nnewi, Nigeria

The role of Ferritin in monitoring disease progression in immune compromised HIV individuals with an underlying active infection like malaria is a subject of growing research. Ferritin being an acute phase protein, plays important role in assessing the range of damage due to inflammation in immunosuppressed patients leaving in highly endemic malaria regions. The levels of serum ferritin in malaria infected HIV positive individuals in Nnamdi Azikiwe University teaching hospital (NAUTH), Nnewi, Anambra State, Nigeria, was assessed. Questionnaire was used to obtain the demographic details of the participants, and to rule out other inflammatory infections. 88 participants of the age group 18 - 65 years, comprising 24 with HIV infection, 22 with HIV and Malaria co-infection, 22 with Malaria infection, and a control group of 22 individuals with neither HIV nor malaria infection were randomly recruited. Ferritin level was determined using enzyme linked immunosorbent assay technique and a cross sectional prospective study design was used. A significantly high mean serum ferritin level was observed in HIV infected individuals with and/ or without malaria co-infection than in malaria positive and control group (p<0.05 respectively). Serum ferritin level was significantly higher in female participants than in male counterparts (p < 0.05). Serum ferritin level was significantly higher in individuals with CD4 count >500 than in CD4 count ≤ 500 (p < 0.05). Blood pressure was significantly higher in HIV infected and malaria positive individuals when compared with controls. The increased serum ferritin level and higher blood pressure in HIV infected participants suggests active inflammatory process, reduced immunity and hypertension which may have worsened by malaria co-infection. This may subsequently lead to vascular and endothelia damage causing disease severity.

Antiretroviral adverse drug events reported among adult HIV patients in a Nigerian tertiary hospital: A retrospective study

Background: The use of Highly Active Antiretroviral Therapy (HAART) has changed HIV/AIDS from a near-certainly fatal illness to one that can be managed chronically. A significant constraint of HAART is the high prevalence of adverse drug events (ADE) among HIV patients taking them. Objectives: The study determined the frequency and severity of reported antiretroviral adverse events among HIV-infected adults (≥16 years) at the Institute of Human Virology (IHV) Clinic of Nnamdi Azikiwe University Teaching Hospital Nnewi, Anambra State, Nigeria, within five years. Antiretroviral therapies implicated in the reported adverse drug events were also determined. Method: Information on reported ADEs was extracted from the NAFDAC Pharmacovigilance forms in the Pharmacovigilance section of the IHV Clinic Pharmacy. The severity of ADEs was classified using the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) index for categorizing errors. Results: A hundred and nineteen (119) patients reported 161 ADEs within the 5-year study period (2017-2021). Most ADE reports came from females (74.53%) and patients 36-55 years old. Dizziness (31.1%), Rashes (14.3%), and Fatigue (13.0%) were prominent among all the ADE reports documented. TDF/3TC/EFV (57.8%) and AZT/3TC/NVP (11.8 %) combinations were the frequently implicated antiretroviral regimen. All the ADEs reported were mild (Category ‘E’). ADE reports appreciated in the second year and progressively declined afterwards. Conclusion: There is a need to improve the system for antiretroviral ADE reporting through sensitization and developing a specific tool that enhances ADE reports from patients and healthcare providers.

Perspectives of Undergraduate Students on the Academic Workload and Suicidal thoughts at Nigerian University

This study examined the impact of academic activities on suicidal thoughts among undergraduate students of Nnamdi Azikiwe University, Awka. The study adopted a descriptive survey research design. The population comprised of 100 students in Nnamdi Azikiwe University, Awka. The study selected respondents using a simple random sampling technique. Instrument for data collection was a 20 item structured questionnaire titled Perceived Effects of Academic Activities on Suicidal Thoughts Questionnaire (PEAASTQ). The instrument was validated by three experts from the Faculty of Education in Nnamdi Azikiwe University, Awka. The instrument's reliability was established using the Cronbach Alpha coefficient that yielded coefficient values of 0.86 from section A, 0.96 from section B, 0.80 from section C, and 0.96 from section D, indicating that the instrument was valid. The data collected for the study were analyzed using mean and standard deviation. Findings from the study showed that the students agreed that excess academic workload can lead to depression, limit someone's social life, and contribute to suicidal thoughts among undergraduate students and that unplanned, d changes in academic workload negatively impact on someone's mental well-being. Based on these findings, the study recommends among others that there should be an extension of academic sessions to allow for a more balanced and manageable workload throughout the semester. These can help prevent burnout and reduce the cumulative stress of a continuous academic schedule.

Aboveground biomass estimation models for Tectona grandis Linn f. plantation in Nnamdi Azikiwe University, Awka, Nigeria

Tree biomass is considered a useful indicator of structural and functional attributes of forest ecosystems across a wide range of environmental conditions. The aboveground biomass refers to the living vegetation above the soil, including stem, stump, branches, bark, seeds, and foliage. Teak (Tectona grandis Linn f.) is a popular exotic tree species in Nigeria; it is widely grown in both large scale and small community woodlots. The objective of this study was to develop models for estimation of biomass content of Teak plantation in Nnamdi Azikiwe University, Awka, Nigeria for sustainable management. Data on the diameter at breast height (D) and total height (H) of all teak stands in the plantation were recorded. Non-destructive method using an existing equation was used to estimate the aboveground biomass (AGB) of the individual stands from stump diameter. The Data was subjected to descriptive statistics, bivariate correlation analysis and fitted to six (6) linear regression functions. A total of 295 trees were measured with mean AGB of 18.61 kg. Out of the AGB prediction models developed for the study area, the Semi Log 3 (B5) model had the best predictive ability; with the highest adjusted coefficient of determination (0.984) and the lowest standard error of estimate (0.308), and Akaike information criterion (-690.974). Model B5 (B=0.764+0.764D-0.105lnH) is therefore recommended for future inventory and management of the plantation.

Intergroup Conflict and Turnover Intention among Lecturers in Public Universities in Anambra State

Intergroup conflict has caused many employees to leave their jobs with ranging consequences on organizations’ operations. Based on this, the study examines the relationship that exists between intergroup conflict and turnover intention in Anambra State Universities, using Nnamdi Azikiwe University, Awka (UNIZIK) and Chukwuemeka Odumegwu Ojukwu University (COOU) as case studies. The Krejcie and Morgan formula was used to determine the sample size of 344. The data was analyzed using a simple regression model, while ANOVA was used to test the hypothesis. The results showed that in Anambra State’s public universities, intergroup conflict and turnover intention have a statistically significant and positive association. Thus, the analysis suggests that the Federal Government should always honor agreements made with Academic unions in order to forestall future occurrences of industrial action.
