Suspended particulates （TSP） and nitrogen dioxide （NO2） are known respiratory irritants linked to asthma aggravation. This pilot study was designed to investigate the role of these pollutants on the frequency of asthmatic attack on two of the inhabitants of a household. The surveillance of TSP and NO2 in this household commenced a few hours later, after one of the occupants suffered an attack. The TSP load determination was done using a High Volume Gravimetric sampler and a light scattering method via a Haz-Dust 10 μm particulate monitor. Palmes Diffusion tubes for NO2 and a portable Crowcon Gasman toxic gas detector were utilized for NO2 screening. In the first day of monitoring in the living room, the in situ particulate sampler （Haz-Dust） recorded a mean TSP level of 26,000 μg·m^-3. A confirmatory test with the eight hour average Gravimetric sampler gave 25,833 μg·m^-3. With the use of the Gasman toxic gas detector for NO2, the NO2 concentration for the first few hours of sampling was lower than 188 μg·m^-3, the detection limit of this instrument. However, the exact NO2 concentrations for the 7 day monitoring after the attack were 27.50 μg·m^-3 （kitchen） and 12.03 μg·m^-3 （living room） as recorded by the Palmes diffusion tubes.

The suitability of two common and ubiquitously distributed and exotic ornamental plant species in Nigeria-Delonix regia and Casuarina equisetifolia as biomonitors and as effective bioaccumulators of atmospheric trace metals （Cd, Pb, Zn and Cu） has been evaluated. Bark and leaf samples from these plant species were collected in June and July 2006 at five locations in Benin City. Four of the sampling sites were in areas of high traffic density and commercial activities, the fifth site is a remote site, selected to act as a control and also to provide background information for the metals. The plant samples were collected and processed using standard procedures and trace metals were determined using atomic absorption spectrometer. The bark of the plants was able to bioaccumulate the trace metals, especially Pb which originates from anthropogenic contributions in the city. The Pb range of 20.00-70.00 μg/g measured for the bark samples ofD. regia, exceeded the normal plant Pb concentration of 0.2-20.0 μg/g and most Pb data available in literature. The bark of the plants was observed to accumulate more metals compared to the leave, while D. regia was found to be slightly better than C. equisetifolia in trace metal uptake efficiency. Spatial variations in the distributions of Pb and Zn were significant （p 〈 0.05）, and the continuous use of leaded fuel in Nigeria was identified as the predominant source of Pb in the atmosphere.

The Modified Adomian Decomposition Method (MADM) is presented. A number of problems are solved to show the efficiency of the method. Further, a new solution scheme for solving boundary value problems with Neumann conditions is proposed. The scheme is based on the modified Adomian decomposition method and the inverse linear operator theorem. Several differential equations with Neumann boundary conditions are solved to demonstrate the high accuracy and efficiency of the proposed scheme.

Background: Low contraceptive use among all other factors have been implicated in rapid population growth seen in low and lower middle-income countries (LLMICs). This can be attributed to poor knowledge and attitude of the populace towards use of modern contraceptives. Aim: To determine the knowledge, attitude and practice of contraception among pregnant women attending ANC at the University of Port Harcourt Teaching Hospital (UPTH) in Port Harcourt, Rivers State, Nigeria from July 1 to August 31, 2021. Methods: This quantitative study was designed as a descriptive cross-sectional study that recruited 529 women. They were administered with a semi-structured questionnaire which was used to collect their data and responses. The data was analysed using Statistical Product and Service Solutions (SPSS) version 25. Results: According to the findings, 57.3% and 47.1% of the women had poor knowledge and negative attitude towards contraception respectively. About a tenth of the women (9.8%) utilised contraceptives of which 44.2% and 42.3% used the natural method and male condoms respectively. The study also revealed the major reason behind the low use as desire for more children (36.3%). Conclusion: The study showed that the women had poor knowledge and negative attitude towards contraceptives and this translated to poor contraceptive use. Hence, awareness campaigns should be intensified by health workers towards enlightening the populace on the different types, uses and benefits of modern contraceptives.

In this study, we constructed and analysed a mathematical model of COVID-19 in order to comprehend the transmission dynamics of the disease. The reproduction number (RC) was calculated via the next generation matrix method. We also used the Lyaponuv method to show the global stability of both the disease free and endemic equilibrium points. The results showed that the disease-free equilibrium point is globally asymptotically stable if RC RC > 1. We further used the Adomian decomposition method and the modified Adomian decomposition method to obtain the solutions of the model. Numerical analysis of the model was done using Sagemath 9.0 software.

Background: Health challenges that are difficult to manage at primary health centres should be referred to secondary health facilities, and if untreated, to the tertiary hospitals. A good referral should include the patient’s biography, such as age, gender, tribe, religion, occupation, medical history, the reason for the referral, treatments received, and clinical diagnosis. Objectives: To evaluate the referral patterns, indications for referrals, and feto-maternal outcomes for obstetric patients who were referred to the University of Port Harcourt Teaching Hospital. Materials and Methods: A prospective study of patients admitted to the Obstetric unit from January 1, 2021, to December 31, 2022. Data was collected from patients while on admission or clinic visits and recorded in an excel spread sheet. Data was analyzed with the Statistical Package for Social Sciences (SPSS) version 25. Results: Of the 3469 patients were admitted to the obstetric unit, 1476 and 1993 were admitted in 2021 and 2022, respectively. Most (70.35%) of the patients were in the 20-34 years age group, parity 1-4 was the most frequent (66.49%), while 85.39% of patients were booked. 10.46% of the booked patients were referred from other facilities, whereas 89.54% of patients were booked at our facility from the onset. Most common indications of referrals were previous caesarean section (CS) at term (40.09%) and hypertensive disorders of pregnancy (17.59%). The outcome for 2021 indicated 17 maternal deaths, 132 fetal deaths and 1010 live births, giving maternal mortality ratio (MMR) as 1810.44 per 100,000 live births and perinatal mortality ratio (PMR) of 130.7 per 1000 births respectively. In 2022, there were 17 maternal deaths, 130 fetal deaths and 1297 deliveries, giving a MMR of 1399 per 100,000 live births and a PMR of 100.2 per 1000 births. Conclusion: The pattern of referral among obstetric patients in this study shows that a lot of the patients do not get adequate care at the lower cadre o

Introduction: The importance of determining health related quality of life in Chronic Kidney Disease patients on dialysis is well established. However, research was limited in establishing the health related quality of life for chronic kidney disease patients on dialysis at University Teaching Hospital-Adult Hospital. Further the effects of haemoglobin levels and adequacy of dialysis on their health related quality of life were unknown. Therefore, the study sought to answer a research question: what is the health-related Quality of Life for Chronic Kidney Disease patients on dialysis at University Teaching Hospital? Method: The study was an analytical cross-sectional study that used a census sampling method. The study participants comprised of 104 patients who sought dialysis services (2020-2021) from the University Teaching Hospital-Renal Unit in Lusaka, Zambia. A structured Kidney Disease Quality of Life Short form (KDQOL-SF 36) was used to collect data. The Data was analyzed using the Statistics and Data software version 13, Chi-square tests, and logistic regression analysis was employed to analyse the data. A confidence interval of 95% was set with a significant level of 0.05. Results: The study included 104 Chronic Kidney Disease patients from the Dialysis Unit at University Teaching Hospital in Lusaka, Zambia. Two-thirds (68%) of the patients had a good overall health-related quality of life with the biological wellbeing having exceptionally high scores. The male gender (66.7%), unemployment (69.4%), and low haemoglobin levels (77.8%) were identified as factors associated with poor health-related quality of life. Conclusion: The health related quality of life of Chronic Kidney Disease patients at University Teaching Hospital was good. Low haemoglobin levels, age, male sex and unemployment were found to be factors associated with poor health related quality of life.
