Item Compliance of Accessibility Features of Selected Shopping Malls with Universal Design Strategies in Nigeria(Civil Engineering and Architecture 13(4), 2025) Sholanke, Anthony Babatunde; Adisa, Ololade SimbiaShopping malls are public facilities that cater to all user groups. To achieve sustainable communities, shopping malls should be designed to meet the accessibility needs of all categories of users. This study assessed the compliance of accessibility features of selected shopping malls with universal design strategies in Nigeria to determine areas for improvement towards promoting inclusivity in the development of the built environment. The study adopted a qualitative research approach. Data from three shopping malls were collected using an observation guide, analysed through content analysis, and presented descriptively with photographs and a table to enhance understanding and provide clarity. The study discovered that while a majority of the accessibility strategies implemented in the malls were satisfactorily compliant with universal design strategies, some of the features did not meet universal design requirements. Key areas found to be lacking include accessibility features largely beneficial for people with disabilities, such as a lack of accessible car parks, slippery floor surfaces, and a lack of lower handrails where main handrails are provided along stairways and ramps for the benefit of people with short stature, and children. Others are the use of open risers, generally considered unsafe for users, and the absence of baby changing toilet facilities. The study suggests retrofitting the shopping malls with accessibility features found to be lacking, to cater for all user groups, including people with disabilities, without compromising the unctionality and aesthetic appeal of the shopping malls. The article is beneficial for policymakers, designers, researchers, and students towards the study, planning, and development of safe, resilient, sustainable, and inclusive environments in conformity with the 11th target of the 17 sustainable development goals.Item Adequacy of the national building code (2006) in promoting Universal Design practices in Nigeria.(Journal of Accessibility and Design for All (JACCES), Volume 15, Issue 2, 2025) Sholanke, Anthony Babatunde; Adisa, O.Universal design seeks to develop environments that are accessible to all users, fostering inclusivity and equal opportunity for everyone. Therefore, effective building regulations are essential to support and advance universal design in developing the built environment. This study examined accessibility provisions of Nigeria’s National Building Code (2006), which is an extensive document that provides set standards for how buildings should be designed, constructed and maintained in Nigeria. The National Building Code was examined to identify gaps hindering inclusivity in the built environment, thereby determining their adequacy in promoting universal design practices, towards enabling individuals to participate in society without physical barriers. The study is a review article that employed qualitative research methods to gather, analyse, and present data. A systematic textual analysis was conducted using secondary sources, including the NBC (2006), the 7 Principles of Universal Design, and key accessible design standards. The data were grouped into themes, and the content was analysed. A descriptive approach and thematic categories were employed to explain the findings. To achieve its findings, the study used two objectives, it examined the existing accessibility provisions of the National Building Code in relations to the requirements of Universal Design Principles and used the provisions found to determine the adequacy of the Code in promoting universal design practices in the development of the built environment. The findings revealed that although the Code contained some relevant accessibility provisions, several of them were vague, lacked detailed specifications or dimensions needed to ensure inclusivity. The study submitted that in its current state, the National Building Code (2006) operational in Nigeria is inadequate in promoting the ideals of universal design. The study recommends a detailed systematic revision of the code to address the identified shortcomings relating to accessibility.Item Public Private Partnership System Initiation Challenges for the Procurement of Public Infrastructure(Covenant Journal of Research in the Built Environment, 2024) Ojelabi, Rapheal; Oyenubi, Adebayo; Afolabi, BaruwaThis study investigates the severity of the challenges associated with the Public-Private Partnership system initiation phase in the procurement of public infrastructure. Also, strategies for managing the barriers associated with the procurement system were evaluated. The study adopted a quantitative research method, conducting a questionnaire survey targeted at selected PPP stakeholders, which includes Architects, Builders, Structural engineers, estate managers, and Quantity surveyors in Lagos and Abuja. The stakeholders were elicited from selected 19 PPP projects using a project-based approach. The data generated were analysed with SPSS 21 using descriptive and inferential tools. Findings from the study revealed the most severe factors associated with PPP procurement system failure to deliver public infrastructure at the inception phase, including a lack of PPP development fund to promote PPP, corruption among the political class, and investors' perception of the country as high-risk for investment. Likewise, strategies considered significant to managing the PPP initiation barriers were unveiled including establishing policies to facilitate PPP at the inception phase, improving transparency in information sharing and providing guarantee legal framework to protect investors. The findings will grant PPP stakeholders insights to the issues responsible for the termination of PPP project collaboration at initiation phase of the procurement system. Also, the unveiling of the PPP challenges and mitigating strategies at the inception phase could guide stakeholders in developing a framework to a successful PPP implementation in a bid to encouraging more participation at this level.Item Government’s motives and investor’s commitment in public-private partnership procurement system adoption(Sciendo, 2025) Amusan, Lekan; Ojelabi, Rapheal Abiodun; Adewolu, Adeoye Olugbenga; Olanipekun, Oladeji OlubunmiThe study examined the government’s motives - ment to infrastructure delivery. The study adopted a quan titative research method with a survey conducted using a structured questionnaire targeted at 384 respondents selected through random sampling. The data were ana lysed using mean, percentile and Pearson correlation sta tistical tools. The study identified 17 key motives respon sible for the government adopting PPP in socio-economic infrastructure delivery. These motives were factored into three main groups: public infrastructure maintenance, financial and economic benefits; improved discipline in the contractual relationship and predictable path in infra structure delivery and integration of innovative approach in enhancing infrastructure delivery. Therefore, the relationships between the three factored government’s motives and investor’s commitments, including finance, management, technical and operational services in PPP, were tested using the Pearson correlation statistical tool. The results showed that the motive for public infrastructure maintenance, financial and economic benefits of the government in PPP showed a significant relationship with the four services commitment of private partners. Also, the government’s motive for improved discipline in the contractual relationship and predictable path in infrastructure delivery showed significant relationships with technical, finance and management commit ments of investors. Lastly, the government’s motive for the integration of innovative approaches in enhancing infrastructure delivery showed a significant relationship with only technical commitment. The outcome indicates that factors measuring government motive and investor's services commitment are mutually dependent and critical in ensuring a sustained relationship among stakeholders in a PPP arrangement for infrastructure procurement.Item Stakeholders’ perspectives on addressing climate change and respiratory health impacts in Nigeria(Pan African Medical Journal, 2025) Akinnola, Olayemi O.; Iseolorunkanmi, Alexander; Niyi-Odumosu, Faatihah; Akinnola, Olayemi O.; Ale, Boni Maxime; Adeloye, Davies; Ozoh, Obianuju BeatriceThe impacts of climate change on respiratory health are increasingly becoming a significant challenge in Nigerian cities, particularly in Lagos and Ogun States. Engaging stakeholders in discussions about climate change and health is crucial for addressing these challenges. The climate change and respiratory health (C2Rest) Nigeria Study team facilitated a stakeholder engagement to discuss climate change and health impacts in Nigeria, aiming to explore feasible solutions relevant to research, policy, and practice. A stakeholder meeting was conducted on April 23rd, 2024, involving from Gardner´s climate change engagement pathways, which examine key drivers (8 questions), barriers (7 questions), and adaptation pathways (3 questions). Data were collected through note-taking, written contributions, audio and video recording, and subsequently transcribed and analysed thematically. A total of 42 registered participants, comprising government officials, academicians, healthcare professionals, community and religious leaders, attended the stakeholder engagement meeting. Participants made group presentations and submitted a total of 380 written contributions. There were varying views on the drivers of climate change, but there was consensus that the most vulnerable populations include the poor, homeless, pregnant women, children, the elderly, and individuals with underlying health conditions. An important barrier identified was the sociocultural belief that climate change is an act of God or spirits. Financial constraints were a recurrent theme in discussions about mitigation and adaptation to climate change. This report provides valuable information on the most vulnerable population to the effects of climate change in Nigeria and identifies sociocultural beliefs and financial constraints as key barriers to the adoption of effective mitigation and adaptation behaviors.Item KNOWLEDGE AND PRACTICES OF HEALTHCARE WORKERS ON ARBOVIRAL INFECTIONS AND DIAGNOSTICS APPROACH IN OGUN STATE, SOUTHWEST NIGERIA(Open Journal of Medical Research, 2024) Ipadeola, A. F.; Akinnola, Olayemi O.; Kolawole, O. M.; Isere, E. E.; Attah, T. A.; Omenyi, I. O.; Afekelu, O. D.; Oreoluwa, A. A.; Oludare, I. T.; Adediran, A. S.; Olasehinde, G. I.Arboviral infections pose significant public health challenges in tropical and subtropical regions like Nigeria. However, these diseases are often undetected by healthcare workers (HCWs) due to the similarity in the presentation to other febrile illnesses like malaria. This study assessed the knowledge and diagnostic practices of HCWs on arboviral infections in Ogun State. A cross-sectional study was conducted among HCWs in selected secondary and tertiary health facilities in Ogun State from October 2022 to September 2023. A semi-structured questionnaire was administered to collect data on sociodemographic characteristics, knowledge of arboviral infections, and diagnostic practices. Stata was used to analyze the data at a 5% level of significance. Of the 96 participants included in the study, 59.4% were female, and 40.0% were ≥35 years old. Nurses constituted the largest cadre (41.7%) while medical doctors (24.0%) were the least represented. Most respondents (68.8%) had never heard of arboviral infections, and 81.3% demonstrated poor knowledge about arboviral infections and diagnosis. Only 6.3% of HCWs had previously suspected or diagnosed an arboviral infection, with clinical diagnosis being more common (66.7%) than laboratory testing (33.3%). Notably, 92.7% of all respondents had no prior training in arboviral infection diagnosis. Good knowledge and previous training received were significantly associated with the diagnosis of arboviral infections among HCWs (p<.05). There is a gap in the knowledge and diagnostic practices of HCWs in the detection of arboviral infections in Ogun State. Thus, comprehensive training programs may be significant in improving awareness, and diagnostic capabilities and enhancing prompt detection and management of arboviral infections in Ogun stateItem Epidemiological and Seasonal Patterns of Respiratory Diseases at a Community Health Facility in Southwest Nigeria: A Five-Year Retrospective Analysis(The Open Public Health Journal, 2025) Oshamika, Oyewumi Oluwaseun; Adebanjo, Ademola Oyeyemi; Onile-ere, Olabode Azeez; Akinnola, Olayemi O.; Eni, Angela ObiagelItem Prevalence and associated risk factors of Staphylococcus aureus nasal colonization among a cohort of immunocompromised individuals in Lagos, Nigeria(BMC Infectious Diseases, 2025) Ogunleye, Bimpe O.; Oshamika, Oyewumi O.; Akinpelu, Sharon O.; Ajayi, Ayodeji S.; Akinduti, Paul A.; Oyedeji, Kolawole S.; Odeniy, Olalekan M.; Akinnola, Olayemi O.Background Immunocompromised individuals are highly vulnerable to Staphylococcus aureus (S. aureus) infections, leading to increased morbidity and mortality. This study aimed to assess the prevalence, virulence, and risk factors associated with S. aureus nasal carriage among immunocompromised individuals in Lagos, Nigeria. Methods A total of 350 participants were enrolled, including 150 HIV/AIDS cases, 50 HIV/TB co-infections, 100 diabetes cases, and 50 controls. Nasal swabs were collected and cultured on Mannitol salt agar for the isolation of Staphylococcus aureus. Presumptive isolates were confirmed using Gram staining, catalase, and coagulase tests. Antimicrobial susceptibility was determined using the Kirby-Bauer disk diffusion method in accordance with CLSI guidelines. Molecular detection of resistance and virulence genes was performed using PCR targeting the mecA gene (methicillin resistance) and pvl (Panton-Valentine leukocidin). A structured questionnaire capturing clinical history and hygiene practices was used to evaluate risk factors for S. aureus carriage. Results The overall prevalence of S. aureus was 14.6% (51/350), S. aureus was isolated in 28% (14/50) of controls, 16.7% (25/150) of HIV/AIDS patients, 14% (7/50) of HIV/TB cases and 5% (5/100) of diabetes cases. Susceptibility to erythromycin was 80.4%, gentamycin, ciprofloxacin and Sulfamethoxazole-Trimethoprim (64.7%) among all S. aureus isolated. Methicillin-resistant S. aureus (MRSA) was detected in 78.4% (40/51) of isolates, predominantly among HIV/AIDS patients (52.5%). pvl genes were identified in 11.8% (6/51) of isolates. S. aureus carriage was significantly associated with recent antibiotic use (p = 0.003) and contact with animals (p = 0.018). Conclusion This study demonstrates a high prevalence of S. aureus among controls compared to immunocompromised individuals. These results highlight the need for further studies to elucidate the relationship between host factors and S. aureus colonization. This could inform targeted strategies for infection prevention and control.Item Age-specific patterns of breast cancer in Nigerian women unraveled through histological analysis(Scientific Reports, 2025) Effiong, Magdalene Eno; Chinedu, Shalom Nwodo; Afolabi, Israel Sunmola; Ezike, Kevin Nwabueze; Oguntebi, Emmanuel Eyitayo; Abdul, Oluwasesan Adelowo; Achusi, Izuchukwu Benerdin; Benye, Tolulope Aanuoluwapo; Omunagbe, Mercy Bella; Ogbodo, Peace NzubechukwuSub-Saharan African women face a high burden of breast cancer, influenced by genetic and lifestyle factors. However, the lack of comprehensive, age-stratified data hinders the identification of risk factors and the development of effective, population-specific interventions. This study aimed to assess age-related variations in breast cancer prevalence among Nigerian women, providing insight into associated risk factors and disease trends. A retrospective review of 3,263 breast histopathology records (9.46% of total from 2015 to 2023) was conducted. Lesions—benign and malignant—were analyzed across five age groups: children and adolescents (0–19), young adults (20–39), middle-aged (40–59), higher-aged (60–79), and elderly (≥ 80), using MS Excel and GraphPad Prism 8.0. Statistical comparisons were performed by age and lesion type. Most cases were in young adults (45.97%) and middle-aged women (33.83%). The left breast was more commonly affected (46.86%) and had higher malignancy rates than the right (44.41%) or bilateral lesions (7.20%). Benign lesions were predominant (56.76%), especially among young adults (57.34%). Malignancy incidence increased with age, peaking in middle-aged women (53.30%). Fibroadenoma was the most frequent benign lesion in children and adolescents and young adults, while fibrosis predominated in middle age. Invasive ductal carcinoma (IDC) was the leading malignant subtype, with a sharp rise by 2023—particularly among middle-aged (172 cases) and young adult women (71 cases). Among 339 immunohistochemically profiled cases, triple-negative breast cancer (TNBC; 42.77%) and ER+/PR+ tumors (36.87%) were most common. TNBC was the only subtype detected in children and adolescents. Middle-aged women bore the highest burden of all subtypes, with a marked increase in TNBC and ER+/PR+ cases in 2023. The rising incidence of aggressive subtypes, particularly TNBC, highlights the need for enhanced molecular diagnostics and personalized therapies. Age-specific trends reinforce the urgency for targeted screening, especially for young and middle-aged Nigerian women.Item Knowledge, practices, and perceptions towards malaria prevention and control among Residents of Canaanland and surrounding areas in Ota, Ogun State, Nigeria: a cross-sectional study(Frontiers in Tropical Diseases, 2025-10-13) Wakai, Theophilus N.; Fiamitia, Carrin; Kintung, Irrinus; Johngwe, Mac; Chinedu, Shalom; Afolabi, Israel S.
