Medicine use among HIV/Aids patients in public hospitals, Kwara State

Background: The prognosis of HIV/AIDS and HIV-related comorbidities has been revolutionized by the use of medicines. However, World Health Organization reported that 50% of patients do not use their medicines as prescribed.Objective: To assess HIV/AIDS patients’ knowledge of the use of medicines dispensed to them.Method: This study was conducted in seven public hospitals in six local government areas, Kwara State. Exit interviews of 780 eligible HIV/AIDS patients were conducted through use of structured questionnaire. Additionally, there were exit observational checks of medicines dispensed to these patients. Descriptive statistics and Fisher Exact test were used for data analyses.Results: Of the 780 study participants, 36.1% had no formal education, 99.9% knew the ‘quantity’ of medicines to be administered, while 99.2% knew the frequency of administration. All the patients knew the route of administration, 96.7% and 94.3% knew the general precautions to avoid concomitant use of dispensed medicines with alcohol or herbal products respectively, while 93.7% of those who received co-trimoxazole knew of the precaution to use “plenty of water” as the vehicle for its administration. There were no significant associations between the patients’ knowledge of these precautions and duration of antiretroviral therapy (P>0.05). However, the patients lacked knowledge of specific precautions of some dispensed medicines.Conclusion: Most of the patients knew of the administration and the general precautions of dispensed medicines. However, lack of knowledge of specific precautions of some dispensed medicines calls for intervention.Keywords: HIV/AIDS patients, Medicine use, Duration of antiretroviral therapy, Public hospitals, Kwara Stat

Climate Change and Its Effects on Agricultural Outputs in Nigeria

This study was carried out to examine the effects of climate change on agricultural productivity in Nigeria. Changes in annual rainfall, temperature, and CO2 emission were used as proxies for climate change. Autoregressive Distributed Lag (ARDL) Bound test approach to co-integration was used for the analysis. The result shows that climate change is insignificant in influencing agricultural productivity in the short run. It is recommended that the proposed agricultural policy should be keenly implemented by taking Nigerian Meteorological Agency (NIMET) prediction into consideration

Investigation of Sub Soil Corrosion Using Electrical Resistivity Method: Federal University Oye Ekiti Phase II Campus as a case study

Electrical Resistivity survey was carried out with the aim of identifying the degree of soil corrosion associated with the sub soil of the Federal University Oye Ekiti phase II. The sub soil resistivity of the area was surveyed and evaluated using Ohmega resistivity meter. The sub soil resistivity parameters were used to delineate the degree of the sub soil corrosion. Four electrodes were inserted into the soil/rock using the Wenner profiling, vertical electrical sounding and Dipole- Dipole array along the traverses with a spacing of 5m and n =1 to 5.In this method, artificially generated electric current(I) was injected into the ground via two current electrodes while the resulting potential difference (V) is measured by another pair of electrodes. The survey revealed that the Southwest and Northwest regions of the study area were associated with high resistivity (200-500 Ω-m).This implies that the soil structure of the region is not corrosive, while the southeast region was associated with low resistivity (20-80 Ω-m) value which implies that the sub soil structure is corrosive. The degree of corrosion increases from the western to eastern part of the study area which may be due to bedrock topography. Of all the layers investigated, the topsoil layer is highly corrosive compare to other layers

Ground Magnetic Attributes For Subsurface Structural Analysis of Foundation Beds in a Sedimentary Terrain in Southwestern Nigeria: OSUSTECH Permanent Site as a case study

The structural failure such as subsidence, collapse and cracking of the walls of buildings in Nigeria has posed a threat or a significant potential hazard to the community in the affected areas. These hazards include gross loss of valuable lives and properties that always accompany such structural failure. Therefore there is need for subsurface structural analysis. The Stop-And-Go method was used for the acquisition of the data. This method is good for subsurface investigation at depths below 30 metres (100 feet). Data for this study were taken at a 10 metres station spacing which is about half that of the expected depth of target. The method requires the technique of measuring total field components at discrete points along the traverses distributed regularly throughout the survey area of interest. The raw data were processed to remove diurnal variations from the total field data measured from the base station. Interpretation of the ground magnetic data revealed that the study area comprises zones underlain with thin to thick overburden. In all the profiles, the regions A and B are associated with the high magnetic values except in the profile 4 in which only region E is associated with high magnetic values. Thus, the region E in the profile 4; the regions A and B in the profiles 1, 2, 3 and 5 are competent zones for the sitting of structures. It can be deduced that the regions of high magnetic susceptibility and high resistivity are competent zones for construction of high rise buildings and other engineering structures. While the regions of low magnetic susceptibility and low resistivity could pose problem of subsidence of the buildings around the region

Prevalence and Predictors of Tuberculosis Coinfection among HIV-Seropositive Patients Attending the Aminu Kano Teaching Hospital, Northern Nigeria

Background: The HIV/AIDS epidemic has been accompanied by a severe epidemic of tuberculosis (TB), although the prevalence of coinfection is largely unknown, especially in developing countries, including Nigeria. The aim of this study was to determine the prevalence and predictors of TB coinfection among HIV-seropositive Nigerians. Methods: The case files of HIV/AIDS patients attending Aminu Kano Teaching Hospital, Nigeria from January to December 2006 were reviewed. Results: A total of 1320 HIV/AIDS patients had complete records and were reviewed, among which 138 (10.5%) were coinfected with TB (95% CI, 8.9% to 12.2%). Pulmonary TB was diagnosed in 103 (74.6%) patients, among whom only 18 (17.5%) were sputum-positive. Fifty (36.2%) coinfected patients had some type of extrapulmonary TB (EPTB); 15 had both pulmonary TB and EPTB. Among the 35 patients with EPTB only, 20 (57.1%) had abdominal TB, 5 (14.3%) had TB adenitis, 5 (14.3%) had spinal TB, 3 (8.6%) were being monitored for tuberculous meningitis, and 1 (2.9%) each had renal TB and tuberculous adrenalitis. The highest prevalence of TB, 13.7% (n = 28), was seen among patients aged 41–50 years. TB coinfection was significantly associated with marital status, WHO clinical stage, and CD4 count. Marital status (OR, 2.1; 95% CI, 1.28–3.59; P = 0.04), WHO clinical stage at presentation (4.81; 1.42–8.34; P = 0.001), and baseline CD4 count (2.71; 1.51–6.21; P = 0.02) remained significant predictors after adjustment for confounding. Conclusions: The moderately high prevalence of TB among HIV-seropositive patients underscores the urgent need for strategies that lead to rapid identification and treatment of coinfection with active or latent TB

Network Restoration for Next-Generation Communication and Computing Networks

Network failures are undesirable but inevitable occurrences for most modern communication and computing networks. A good network design must be robust enough to handle sudden failures, maintain traffic flow, and restore failed parts of the network within a permissible time frame, at the lowest cost achievable and with as little extra complexity in the network as possible. Emerging next-generation (xG) communication and computing networks such as fifth-generation networks, software-defined networks, and internet-of-things networks have promises of fast speeds, impressive data rates, and remarkable reliability. To achieve these promises, these complex and dynamic xG networks must be built with low failure possibilities, high network restoration capacity, and quick failure recovery capabilities. Hence, improved network restoration models have to be developed and incorporated in their design. In this paper, a comprehensive study on network restoration mechanisms that are being developed for addressing network failures in current and emerging xG networks is carried out. Open-ended problems are identified, while invaluable ideas for better adaptation of network restoration to evolving xG communication and computing paradigms are discussed

Comparative Studies of Water and Sediment Qualities of Some Dams in Kwara State

Potable water is becoming progressively scarce due to anthropogenic pollution and it has necessitated monitoring of water quality of rivers and dams as a subject of ongoing concern and research. This study was conducted to assess the quality of water collected from four different dams (Agba, Igbaja, Oloru and Omu-Aran) in Kwara State, Nigeria using standard procedures. Water and sediment samples were collected from three different spatial locations on the dams. The average values of most physicochemical parameters like pH, temperature, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Total Dissolved Solid (TDS), Total Hardness (TH), Alkalinity, some nutrients such as chloride (Cl-), sulphate (SO42-), phosphate (PO43-), nitrate (NO3-) and some heavy metals such as Cu, Zn have values that were within World Health Organisation (WHO) guidelines for drinking water for each of the dams while Cd and Fe concentrations were observed to be much higher than WHO guidelines for drinking water. This could be as a result of anthropogenic input. The dams’ sediments analyzed for heavy metals showed that Mn, Zn and Cd were high in the dams, which can be easily washed into the water body through leaching, thereby causing detrimental effect to the consumers.
