Mathematical modeling of drying of pretreated and untreated pumpkin.

Abstract: In this study, drying characteristics of pretreated and untreated pumpkin were examined in a hot-air dryer at air temperatures within a range of 40–80 °C and a constant air velocity of 1.5 m/s. The drying was observed to be in the falling-rate drying period and thus liquid diffusion is the main mechanism of moisture movement from the internal regions to the product surface. The experimental drying data for the pumpkin fruits were used to fit Exponential, General exponential, Logarithmic, Page, Midilli-Kucuk and Parabolic model and the statistical validity of models tested were determined by non-linear regression analysis. The Parabolic model had the highest R2 and lowest χ2 and RMSE values. This indicates that the Parabolic model is appropriate to describe the dehydration behavior for the pumpkin.

The increasing prevalence of diabetic nephropathy as a cause of end stage renal disease in Nigeria

Abstract: The incidence of diabetic nephropathy, the leading cause of chronic kidney disease in the western world has increased by 150% in the past 10 years in the United States, with similar trends in Europe and Japan. It is apparent from the present study that diabetic nephropathy may be assuming an increasing role as a cause of chronic kidney disease in Nigeria.

Equilibrium, kinetic, and quantum chemical studies on the adsorption of Congo red using Imperata cylindrica leaf powder activated carbon

Abstract: Leaf powder of spear grass, otherwise known as Imperata cylindrica (IC), was used to prepare activated carbon. The Imperata cylindrica activated carbon (ICAC) prepared was used for the removal of Congo red (CR) dye from aqueous solution. Operation parameters such as initial dye concentration, contact time, adsorbent dosage, pH, and temperature were studied in batch systems. Equilibrium was attained in 150 and 180 min at lowest and highest concentrations, respectively. Maximum adsorption was observed at pH 3. Quantum chemical studies suggested that the protonation of aniline groups and minimal molecular size at planar geometry coupled with electrostatic interaction enhances the adsorption at low pH. Adsorption data were tested using pseudo-first-order and second-order reaction kinetics; the latter was found to be more suitable with a coefficient of determination of ≥0.99. The adsorption process fits Langmuir isotherm model better than the Freundlich model, with a maximum monolayer coverage of 313 mgg−1. Th...

Economic burden and catastrophic cost among people living with type2 diabetes mellitus attending a tertiary health institution in south-east zone, Nigeria

Abstract: Diabetes mellitus (DM) is a life-long illness that affects the quality of life, requiring close monitoring and control. Type 2 DM is preventable and controllable but increasing cost of care could hinder access to quality care because of inability to pay leading to high morbidity, mortality and productivity losses. The people living with diabetes mellitus (PLWD) in Nigeria have high risk for high economic burden and catastrophic expenditure not only because they make frequent visits to the health facilities, report late with complications but also pay out of pocket at the point of accessing care. The aim of this study was to assess the magnitude of economic burden borne and catastrophic costs incurred by PLWD in Nigeria. Cross-sectional descriptive survey design was used to study a sample of 308 type2 PLWD managed at a tertiary health institution, South east Nigeria using semi-structured, prevalidated questionnaire. Data collection period was 2 months. The major findings were economic burden of type 2 DM of N56,245 ($356). Catastrophic direct cost was 45 % at 30 % threshold (the determinant level for catastrophic spending set). All socio-economic status (SES) groups suffered catastrophic expenditure but the poorest quartile had the highest incidence. Economic burden of DM was high for PLWD who also suffered high catastrophic costs due to the impact of out of pocket payment. PLWD need financial protection especially for the poorest since they buy from the same market and incur same costs. Policy decision making to assist the PLWD cope with cost of care is needful in Nigeria and nations with related problems.

Pattern of contraceptives choice among the married women attending the family planning clinic of a tertiary health institution.

Abstract: Background: Rampant population growth is the most fundamental problem of our times. It affects adversely the advancement of nations and the wellbeing of all peoples. The fertility rate in Nigeria remains high at a national average of about 5.2 children per woman. When a woman effectively uses a modern method of contraceptive she is less likely to be exposed to the hazards of grand multiparity, and also unlikely to resort to dangerous illegal abortion. Method: This is a retrospective study, a review of the records of the family planning clinic of Ladoke Akintola University of Technology Teaching Hospital, Osogbo was undertaken. These were new clients coming for the first time to the family planning clinic of the institution from January, 2001 to December 2006. Result: A total of 1355 married women were coming for the first time to the family planning clinic within the study period, and their age range between 18 and 51 years with a mean of 33.5+6.1 years. 170 (12.5%) were Para 1, Para 2-4 were 855 (63.1%), while Para 5 and above were 330 (24.4%). The clients source of information about family planning was: family planning clinic personnel 1039 (76.7%), media (print and electronic) 152 (11.2%), friends and relatives 127 (9.4%), and community health workers 37 (2.7%). Intrauterine contraceptive device was the most chosen method by the clients 1011 (74.6%), while condom was the least chosen 3 (0.2%); 264 (19.5%), and 77 (5.7%) clients chose injectables and pills, respectively. Conclusion: An increase in the level of knowledge on modern contraceptive methods through mass and interpersonal communications could be one of the key strategies to increase the utilization rate of modern contraceptive methods.
