Full time adult credential students?instructional preferences at California State University, Long Beach: pedagogy or andragogy?

This study investigated the instructional preferences of full time adult credential students after they took a live course called Principles of Adult Education at California State University, Long Beach (CSULB) in the fall semester of 2002. These full time adult credential students had been working on their adult teaching credentials to meet the competencies specified by the California Commission on Teacher Credentialing. The course introduced students to Andragogy developed by Malcolm Knowles out of the andragogical model developed by Lindeman (1926). The study used Principles of Adult Learning Scales (PALS), advanced by Gary Conti in 1983 to measure instructional preferences. Data were collected from 30 (100% of 30) full time adult credential students enrolled in a live course to determine their instructional preferences of helping adults learn. The results of the study showed in most cases these adult learning professionals taught adult students andragogically; in some cases they taught adult students pedagogically.

Level of Adherence to Cytotoxic Drugs by Breast Cancer Patients’ in Lagos State University Teaching Hospital

Background: Breast cancer is one of the most common malignant diseases in women and adjuvant combination chemotherapy has been shown to reduce mortality from this disease. Adherence to medical treatment is a multifaceted issue that can substantially alter the outcomes of therapy. Patient non-adherence to chemotherapy is the ultimate barrier to the treatment effectiveness. Objective: This study was carried out to determine the relationship between cancer chemotherapy adherence and breast cancer staging, patient’s perception of cancer care and patient’s socio-demographic characteristics. Material and method: This was a cross sectional study selection of respondents and was based on simple random sampling technique, 184 patients were interviewed and data was collected using a semi-structured questionnaire to obtain socio-demographic data, adherence data, and facility-related information. Results: There was a significant association between marital status and non-adherence (P?= 0.013). Both separated and single subjects had higher proportion of non-adherence compared with married subjects. Analysis of perception of chemotherapy care revealed a significant association between the satisfaction score and non-adherence, with non-adherent patients showing higher scores or being less satisfied. The quality of service (P?= 0.0052);rating of needs been met (P?= 0.0079);rating on whether the services helped the subject (P?= 0.0405);rating on the general satisfaction of the services provided (P?= 0.0115);and rating on whether subject would seek help again (P?= 0.0320) all had a significant association with non-adherence. Conclusion: The awareness of oncologist and patient of the problem of non-adherence and communication regarding the importance of adherence to therapy may improve health outcomes.

The Pattern of Comorbidities of Childhood Asthma as Seen in the Rivers State University Teaching Hospital, Nigeria

Background: Asthma exits with comorbidities which can affect the quality of life of children with asthma. Objective: To identify the common comorbidities with asthma, identify factors associated with the presence of specific comorbidities and evaluate their impact on asthma severity and control among children attending the respiratory clinic in the Rivers State University Teaching Hospital. Materials & Methods: All asthma cases seen in the paediatric respiratory clinic, from 1st November 2014 to 30th October 2019 were consecutively recruited. Results: Of 264 children with asthma, 190 (72.0%) had other comorbidities with a F:M ratio of 1.56:1. Difficulty in breathing, chest pain, and the degree of asthma control were significantly associated with having other comorbidities while SPO2 at 1st consult was significantly lower in children with comorbidities, P value < 0.05. Allergic rhinitis 116 (43.9%), adenotonsillar hypertrophy 99 (37.5%), atopic dermatitis 54 (20.5%), allergic conjunctivitis 37 (14%), food allergy 27 (10.2) and Gastroesophageal reflux14 (5.3%) were the commonest comorbidities identified. Majority (24, 88.9%) had allergy to one type of food. Children < 3 years and those whose age at diagnosis was <2 years were significantly at lower risk of having atopic dermatitis. Gastroesophageal reflux disease was significantly more likely to be seen in children aged > 11 years, overweight children, and those presenting with chest pain or chest tightness. Presence of various comorbidities increased the odds of having a more severe asthma, and likelihood of which increased with increasing number of coexisting comorbidities. Conclusion: The prevalence of allergic comorbidity is high among asthmatic children with allergic rhinitis being the commonest cause. Most children with asthma have more than one allergic comorbidity. A comprehensive evaluation of these comorbidities is thus essential in the management of asthmatic children for improved outcomes and quality of life.

Lassa Fever: Patients Profile and Treatment Outcomes at Benue State University Teaching Hospital Makurdi, North-Central Nigeria

Lassa fever is a viral haemorrhagic fever found mostly in West Africa where it is endemic but generates periodic outbreaks in the dry seasons. The virus is spread by the rat species named mastomys natalensis. While the illness is minor in most cases, the mortality is significant in hospitalized patients. Few completely equipped treatment centers existed in Nigeria previous to current increase in frequency requiring demand for new treatment centers without the full complement of essential capabilities. Aim: To analyze the profile and treatment outcome in patients hospitalized in one of such new resource-constrained centers at the Benue State University Teaching Hospital Makurdi, Nigeria. Methodology: This was a retrospective, descriptive hospital-based research encompassing January 2020 to March 2023. Medical records of those admitted to the isolation center were reviewed. The relevant data was coded and analyzed using IBM SPSS version 23. Results: One hundred and ten (110) individuals were hospitalized for probable or suspected Lassa fever throughout the research period. A total of 35 confirmed patients satisfied the inclusion criteria and were included as the study subjects. There were 23 (65.7%) men and 12 (34.3%) females. Their mean age was 35.36 ± 12.21 years (range 15-61 years). The treatment outcome showed that 24 (75%) survived and were discharged, 5 (15.6%) were referred out of the facility for dialysis and 3 died, providing a mortality of 8.6%. The causes of mortality in study patients were acute kidney injury and encephalopathy. Conclusion: Lassa fever is endemic in Benue state with all types of individuals afflicted. The outcome of treatment was good despite resource difficulties. Lassa fever can be successfully managed even in resource-challenged situations typically encountered in developing countries.

A Collaborative Service to the Community: A COVID Vaccine Clinic Provided by a Mid-State University

The opportunity to offer immediate service to a local community in need of an additional COVID Vaccine Clinic was welcomed by the School of Nursing (SON) at Middle Tennessee State University (MTSU). This opportunity not only opened a door by providing a much-needed community service but also afforded students an enriching opportunity to enhance their clinical skills in a venue not always recognized as an available or accessible resource. A COVID Vaccine Clinic was planned in collaboration with the School of Nursing, University Health Services, and the County Health Department to provide COVID vaccines to the Middle Tennessee area. A multidisciplinary committee met weekly to organize the COVID Vaccine Clinic opening this opportunity to the community two days per week. During the initial COVID Vaccine Clinic planning committee meetings, a variety of roles and responsibilities were identified to ensure the clinic would be planned, coordinated, and organized as efficiently as possible. When the clinic opened, weekly meetings continued to identify issues such as supply distribution problems, procedures related to various aspects of care, and debriefings describing the activities of each clinic day to note any areas in need of improvements. The School of Nursing Lobby, located on the MTSU campus, was the designated area chosen for the clinic. Many faculty and students along with numerous campus volunteers worked together enabling thousands of members of the community to receive vaccinations. The interdisciplinary experience was a success and served to bring positive learning outcomes to all members of the faculty and students involved.

Prevalence of HIV, Hepatitis B, and Hepatitis C in Rivers State University, Port Harcourt: Outcome of a Medical Outreach

Background: Infectious diseases associated with Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), and Hepatitis C Virus (HCV) continue to pose significant public health challenges that necessitate continuous surveillance and interventions. This study investigates the prevalence of HIV, HBV and HCV infections within the academic community of Rivers State University, Port Harcourt, Nigeria. Given the potential for transmission in university settings and the importance of early detection and intervention, this research explores the extent of these infections and evaluates the outcomes of a medical outreach program aimed at addressing them. Methodology: A cross-sectional study design was employed to recruit 513 participants using a convenience sampling approach between the 20th and 22nd of April 2022. Participants included students and staff members who voluntarily consented to the medical outreach and study. Serological assays were utilized to identify HIV, HBV and HCV infections. The medical outreach program’s design, implementation, and outcomes were evaluated, focusing on testing uptake, counselling utilization, and linkage to care. Statistical analysis employed GraphPad Prism version 9 software. Result: The study revealed low prevalence rates of HIV (0.6%), HBV (1.2%), and HCV (0.6%) infections within the university population. Age-based analysis indicated a slightly higher prevalence in the 15 - 24 age group. Gender-wise, HBV showed a marginal difference, with 1.3% among females and 0.9% among males. The medical outreach program achieved a testing uptake of 80.8%, with 75% utilizing counselling services, and 75% of those identified with infections successfully linked to care. Conclusion: This study provides valuable insights into the prevalence of infections and the effectiveness of a medical outreach program within a university community. While low prevalence rates are encouraging, the findings emphasize the continued importance of awareness and prevention efforts. The success of the outreach program in encouraging testing, providing counselling, and facilitating care linkage underscores its potential as a model for future interventions. Further research should delve into determinants of infection prevalence and barriers to care linkage for a more comprehensive understanding and improved intervention strategies.

Association of Obesity and Dyslipidaemia with Type 2 Diabetes in Outpatients of Enugu State University Teaching Hospital （ESUTH）in Enugu Nigeria

Obesity is known to be a major risk factor of type 2 diabetes （T2D） and responsible for most lipid abnormalities associated with the disease but limited data on such association are available for diabetic patients of Igbo ethnicity in the South East region of Nigeria. A case-control study involving 72 T2D patients and 75 non-diabetic （ND） patients （control） ofIgbo ethnicity was conducted. Demographic and anthropometric data were obtained followed by blood collection for the determination of fasting blood sugar （FBS）, total cholesterol （TC）, triglyceride （TG）, high density lipoprotein （HDL） and low density lipoprotein （LDL）. Obesity based on waist circumference （WC） was significantly higher （p 〈 0.001） in T2D patients compared to their non-diabetic counterparts. Similarly, TC, TG and LDL levels were significantly （p 〈 0.001） higher in T2D patients while HDL was significantly lower （p 〈 0.001） in T2D patients compared to the control. The proportion of dyslipidaemia characterized by high TC, high TG, high LDL and low HDL was significantly higher （p 〈 0.001） in T2D patients. BMI correlated positively （p 〈 0.05） with WC, TC, and LDL while FBS correlated positively （p 〈 0.05） with TG but negatively with HDL. In conclusion, dyslipidaemia characterised by hypercholesterolaemia, hypertriglyceridaemia, elevated LDL and reduced HDL, as well as obesity were associated with T2D and correlated with FBS in this population.

APPLYING PROJECT BASED LEARNING IN AN UNDERGRADUATE DESIGN AND CONSTRUCTION PROGRAM AT APPALACHIAN STATE UNIVERSITY

INTRODUCTION Project based learning(PBL)fully engages students in the subject area,promotes teamwork,transdisciplinary collaboration,allows student teams to engage and solve community design problems and can ultimately lead to broader student worldviews.PBL,however,presents significant curricular challenges,including project definition and meaningful student assessment.The authors began the process of exploring PBL through a National Science Foundation Transformation Undergraduate Education in Science,Technology,Engineering and Mathematics(TUES)award.The program was piloted for two semesters under the TUES award and has now completed its eighth semester overall operating as a special curricular track in parallel with an existing,traditional curricular program in Building Science.With four years of dedicated PBL program experience to inform their efforts,the authors are currently reworking the existing Building Science program curriculum to fully integrate a PBL capstone during the senior year while establishing a clear curricular path,creating a sound base of projects,and maintaining resource limits that include,but are not limited to,facilities,materials and personnel.In this paper,the authors discuss their successes and difficulties with imple-menting PBL in an undergraduate design and construction program by reviewing twelve years of both spontaneous and planned project based PBL experiences in an undergraduate design and construction program.

A ROADMAP FOR BUILDING CLIMATE RESILIENCE AT HIGHER EDUCATION INSTITUTIONS:A CASE STUDY OF ARIZONA STATE UNIVERSITY

Over the past few years, more and more higher education institutions have pledged to achieve carbon neutrality and designed and adopted Climate Action Plans. Although many higher institutions are adopting climate action plans, few are integrating resil-ience principles and priorities, which are essential for understanding institutions’ adaptive capacity for dealing with climate change. There is little existing research on how higher education institutions can implement climate resilience programs, behav-iors, and policies into their planning process and campus-communities. To address this gap, this case study explores Arizona State University’s process of designing and implementing a climate resilience plan and outlines best practices other higher educa-tion institutions can utilize to create their own climate resilience plan. We critically discuss the importance of climate resilience at the higher education level, outline steps necessary for designing an inclusive and holistic climate resilience plan, and provide examples of important techniques used to design the climate resilience plan.

限制热量摄入6个月对超重者寿命指标、代谢调节及氧化应激的影响——随机对照试验AuthorAffiliations：PenningtonBiomedicalResearchCenter．LouisianaStateUniversity．BatonRouge；andGarvan．InstituteforMedicalResearch．Dadinghurst，AustraIia（DrHeilbronn）．

背景：长期限制热量摄入可延长啮齿类动物的寿命。但是，尚未有研究观测长期限制人体热量是否会影响其寿命及氧化应激指标，降低代谢率。 目的：在超重但不肥胖（体重指数为25—30）的人群中研究限制热量6个月伴／不伴运动对其产生的影响。 设计、地点及参试者：于2002年3月至2004年8月在位于路易斯安娜州首府巴顿鲁治的研究中心对48名不好动的健康人进行随机对照研究。 干预：参试者在6个月内随机分为4个组：对照组（饮食可维持体重）；限制热量组（限制基线所需能量的25％）；限制热量＋运动组（限制12．5％的热量＋运动增加12．5％的能耗）；极低热量饮食组（每日摄入890keal，直至体重减少15％，随后采用维持体重的饮食）。 主要观测指标：机体组成；硫酸脱氢表雄酮（dehydroepiandrostemne sulfate，DHEAS）、葡萄糖及胰岛素水平；蛋白羰基化合物；DNA损伤；24小时能耗；核心体温。 结果：6个月时各组体重变化的均值（标准误）为：对照组-1．0％（1．1％）；限制热量组-10．4％（0．9％）；限制热量＋运动组-10．0％（0．8％）；极低热量饮食组-13．9％（0．7％）。6个月时，各干预组空腹血糖水平较基线明显降低（P均〈0．01），而DHEAS和葡萄糖水平没有改变。限制热量组及限制热量＋运动组核心体温有所下降（P均〈0．05）。对机体组成进行校正后发现，对照组24小时静息能耗无变化，但限制热量组（-135kcal／d[42kcal／d]）、限制热量＋运动组（-117kcal／d[52kcal／d]）和极低热量饮食组（-125kcal／d[35kcal／d]）24小时静息能耗有所下降（P均〈0．008）。上述“代谢调节”（超出预计值的-6％）与对照组相比存在显著差异（P〈0．05）。6个月时，各组蛋白羰基化合物的浓度较基线时无变化，而各干预组DNA损伤有所减少（P〈0．005）。 结论：我们的研究结果显示，长期限制热量可降低人类寿命的2种指标（即空腹胰岛素水平和体温）。此外，我们的研究结果还支持下述理论，即限制热量能降低代谢率，且超过缩小代谢面积产生的相应效应。我们尚需开展远期研究来评价限制热量能否延缓人类衰老过程。

Prevalence and Antimicrobial Susceptibility Pattern of Asymptomatic Urinary Tract Infections of Bacterial and Parasitic Origins among University Students in Redemption Camp, Ogun State, Nigeria

Asymptomatic urinary tract infections (UTIs) of bacterial and parasitic origins occur in both males and females where bacteria and/or parasites are present in the urine, with the absence of clinical signs or symptoms in the host. Using microbiological methods, mid-stream urine collected from sixty (60) Redeemer’s University students comprising apparently healthy 30 male and 30 female undergraduate students were examined. The samples were cultured on CLED and MacConkey agar. Bacteriuria was observed in 15 (25%) of the samples while there was no significant growth in 34 (56.7%), and no growth in 11 (18.3%). Prevalence of significant bacteriuria was higher in females 11 (73.3%) than males 4 (26.7%). The bacteria isolated were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptococcus spp, and Klebsiella spp. The isolates were resistant to amoxycillin, augumentin and cotrimoxazole but most were highly susceptible to ofloxacin. Schistosoma haematobium and Trichomonas vaginalis were the two asymptomatic UTI-causing parasites isolated from the samples used in this study. Out of the 30 males examined using the microscopy method, 1 (1.67%) had T. vaginalis while the females had higher prevalence of 2 (3.33%) out of 30 females examined. Out of the overall participants examined for S. haematobium eggs, 15 (25%) had Schistosomiasis in which the males had higher prevalence of 10 (33.33%) while the females had 5 (16.67%). These results are lower than those observed in similar rural communities in Nigeria possibly due to effective health education, availability of potable water, higher-than average income and hygienic practices on Redemption Camp, Ogun State, Nigeria.
