The use of non-prescription medicine versus self assessed health: evidence from Malaw

Background: The use of medicine is an important part of any health care process and the improvement of health status of any population. While some medicines are legitimately prescribed by practitioners, others take drugs not prescribed by practitioners when they suffer from illness or injuries. The effect of such actions on the health of individuals cannot be overlooked. Even though majority of health policies in developing countries have focused on chronic diseases and the functioning of health systems, abuse of drugs or medicines is a serious population health problem that deserves equal attention. The objectives of the current study are to examine the social and economic dimensions of the use of non-prescription medicines and to determine the effect it has on self-assessed health of individuals. Methods: The study employs data from the second Integrated Household Survey of Malawi with a sample of 2506 individuals who reported an incidence of illness or injury over the past two weeks before the survey. Regression analysis is conducted at two levels, first is a probit model to identify socio-economic factors that influence the use of non-prescription medicine. The second step uses an ordered probit to model the effect of the use of non prescription medicines on self-assessed health of individuals. Results: Results from the probit model show that availability of a health facility in the community negatively affects the use of non-prescription medicines. Age of the individual and the total household health expenditure relate to higher use of non-prescription medicine. Results from the ordered probit model shows that individuals who used non-prescription medicines were likely to report lower categories of self-assessed health. Conclusions: While policy makers need to engage in public campaign to educate the population on the health risks posed by the use of non-prescription medicines, attention also has to be paid to the social and economic characteristics of the population. Efforts to provide health facilities in communities where they do not exist and improve existing ones will be a crucial step in reducing the use of non-prescription medicines

The use of paradigms in information research

Studies of human behavior usually require the adoption of a research paradigm with the objective of improving the credibility and generalisability of the study. Applying research paradigms in information research is noted to vary from one researcher to another based on the investigator's choice as well as the character of the issue under investigation. The differences in the application of research paradigms in information research do not rely on philosophical assumptions alone, but also on the practical consequences of the inquiry and the interpretation of the findings. The four most broadly applied paradigms in research - pragmatism, interpretivism, positivism, and post-positivism and how the adoption of these paradigms fit into information research was examined. Findings indicate that application of research paradigms in information research is beneficial. However, information researchers are advised to be cautious of the weaknesses of the paradigm they would adopt for a study.

The use of placebo in a trial of rectal artesunate as initial treatment for severe malaria patients en route to referral clinics: Ethical issues

Placebo-controlled trials are controversial when individuals might be denied existing beneficial medical interventions. In the case of malaria, most patients die in rural villages without healthcare facilities. An artesunate suppository that can be given by minimally skilled persons might be of value when patients suddenly become too ill for oral treatment but are several hours from a facility that can give injectable treatment for severe disease. In such situations, by default, no treatment is (or can be) given until the patient reaches a facility, making the placebo control design clinically relevant; alternative bioequivalence designs at the facility would misrepresent reality and risk incorrect conclusions. We describe the ethical issues underpinning a placebocontrolled trial in severe malaria. To protect patients and minimise risk, all patients were referred immediately to hospital so that each had a higher chance of prompt treatment through participation. There was no difference between artesunate and placebo in patients who reached clinic rapidly; among those who could not, a single artesunate suppository significantly reduced death or permanent disability, a finding of direct and indirect benefit to patients in participating villages and elsewhere.

Use of Pleurotus eous Strain P-31 Spent Mushroom Compost (SMC) as Soil Conditioner on the Growth and Yield Performance of Capsicum annuum L. and Solanum lycopersicon L. Seedlings under Greenhouse Conditions in Ghana

The objective of this study was to investigate the influence of spent mushroom compost of Pleurotus eous strain P-31 on the growth and yield performance of pepper and tomato seedlings under greenhouse conditions. Sandy loam soil was combined with different percentages of SMC to obtain the following combinations (0, 5, 10, 15, 20, 25 and 30) %. Lower concentrations SMC5, SMC10 and SMC15 promoted vegetative growth (plant height, leaf area, chlorophyll content, number of leaves and axillary branches) of the two test plants. Tomato seedlings grown in SMC10 recorded the highest plant height (50.3 ± 7.2cm); leaf area (378.8 ± 1.2cm2); number of floral buds (51) and flowers (28) whereas SMC5 recorded the highest chlorophyll content 34.1 ± 0.9CCI though SMC15 recorded the highest number of leaves (8). Tomato seedlings grown in SMC30 produced both the maximum number of fruits (8) with corresponding high weight (34.2 ± 7.7g). Pepper seedlings grown in lower concentrations (SMC5–15) recorded the highest plant heights (29.8–30.8cm), chlorophyll content (20.3CCI) and leaf area (53.5–66.2 cm2). Although the different combinations of sandy loam soil and SMC did not significantly (p ≥ 0.05) affect the number of axillary branches developed; different combinations significantly (p ≤ 0.05) affected the number of floral bud, flower and fruit, weight of fruits formed and value of each of these increased with increasing percentage of SMC. Pepper seedlings grown on SMC30 recorded the maximum number of floral buds (32.0 ± 3.6), number of flowers (19.4 ± 1.3), number of fruits (10.8 ± 1.2) and weight of fruits (31.9 ± 3.4g). Tomato seedlings raised on SMC100 (spent mushroom compost only) and soil only did not significantly (p ≥ 0.05) differ from each other however, was statistically significant (p ≤ 0.05) from amended sandy loam soil by all criteria investigated. The study shows that SMC provide favourable soil conditioners for the cultivation of fruits, vegetables and foliage crops as it improved growth and yield of tomato and pepper seedlings.

The Use of Recycled Polyethylene in Water-Oil Emulsion for Lightweight Concrete

This study was to determine the suitability of recycled waste polyethylene (WPE) processed into water-oil emulsion for lightweight concrete applications. The processed WPE in the form of polyethylene emulsion (PE-e) is to promote physical interaction between the polymeric material and the cementitious matrix. The PE-e used was also to partially replace concrete mix composition by PE-e_1, PE-e_2.5, PE-e_5, and PE-e_10 percents for reference concrete and to introduce plasticity into the mechanical behaviour of the concrete. The PE was processed into PE-e to promote affinity for water, and this hydrophilicity was prominent in PE-e_1 and PE-e_2.5 percent concretes. Concretes with PE-e_1 and PE-e_2.5 percent formed good miscibility with the cementitious matrix. The density of the PE-e concrete decreased to 13.68% with 10% PE-e at 28 days. The replacement of mix constituents of PE-e_1, PE-e_2.5, and PE-e_5 percent induced elastic to plastic behaviour in the concrete coupled with low water absorption. The FTIR data showed characteristic peaks of 3378 cm-1, 1740 cm-1, and 1148 cm-1 in the PE-e. Using optical microscopy, it was shown that the PE particles were homogenously dispersed in the concrete matrix. The study shows the feasibility of using PE-e_1 percent to produce structural lightweight concrete and up to PE-e_10 percent for nonstructural applications mainly for light, non-load-bearing partitions

Use of refractometry and colorimetry as field methods to rapidly assess antimalarial drug quality

The proliferation of counterfeit and poor-quality drugs is a major public health problem; especially in developing countries lacking adequate resources to effectively monitor their prevalence. Simple and affordable field methods provide a practical means of rapidly monitoring drug quality in circumstances where more advanced techniques are not available. Therefore, we have evaluated refractometry, colorimetry and a technique combining both processes as simple and accurate field assays to rapidly test the quality of the commonly available antimalarial drugs; artesunate, chloroquine, quinine, and sulfadoxine. Method bias, sensitivity, specificity and accuracy relative to high-performance liquid chromatographic (HPLC) analysis of drugs collected in the Lao PDR were assessed for each technique. The HPLC method for each drug was evaluated in terms of assay variability and accuracy. The accuracy of the combined method ranged from 0.96 to 1.00 for artesunate tablets, chloroquine injectables, quinine capsules, and sulfadoxine tablets while the accuracy was 0.78 for enterically coated chloroquine tablets. These techniques provide a generally accurate, yet simple and affordable means to assess drug quality in resource-poor settings.

The Use of Religious Capital as a Coping Strategy in Self‑care by Type 2 Diabetes Patients in a Ghanaian Hospital

Given the importance Ghanaians attribute to spirituality and religiosity in terms of disease causation and management, this study explored the use of religious capital as a coping strategy by individuals with type 2 diabetes mellitus in self-care at the Techiman Holy Family Hospital Diabetes Clinic in the Bono East Region of Ghana. An exploratory descriptive qualitative research design was employed for the study. Semi-structured interviews were conducted with a convenience sample of twenty-seven (27) individuals recruited from the diabetes clinic. Content analysis was employed to find themes, which included: (1) Use of Prayer and Fasting for Courage from God, (2) Reliance on God as the Creator of Human Beings who Cures and Heals Diseases in the Body, (3) God as Source of life in times of Illness (Drawing life from God in times of illness), (4) Faith and Hope in God, and (5) Doctors and Nurses as Substitutes for God. The findings advocate the need to incorporate religiosity and spirituality into the provision of healthcare for individuals with diabetes to help them live productive lives.

Use of reusable menstrual management materials and associated factors among women of reproductive age in Ghana: analysis of the 2017/18 Multiple Indicator Cluster Survey

Background: The use of unsafe materials to collect menstrual blood predisposes women and girls to infections. There is a paucity of literature on the utilization of reusable menstrual materials in sub-Saharan Africa. This study examined factors associated with the use of reusable menstrual management materials among women of reproductive age in Ghana. Findings from this study can inform menstrual health programmes and reproductive health policy to address menstrual hygiene and specific areas of emphasis. Methods: We analysed secondary data from the 2017/18 Ghana Multiple Indicator Cluster Survey. Descriptive statistics were employed to compute frequencies and percentages, while Chi-square and complex sample Binomial Logistic Regression was conducted to identify factors associated with the use of reusable menstrual materials. Results: Half (52%) of the respondents were below 30 years old; mean (± sd) = 30.7(9.0). Thirteen percent used reusable materials to collect menstrual blood during their last period. Women aged 45–49 years (AOR = 5.34; 95% CI 3.47–8.19) were 5 times more likely to manage menstruation with reusable materials compared with those aged 15–19 years (p < 0.05). Women classified in the middle wealth quintile (AOR = 0.66; 95% CI 0.50–0.88) were 34% less likely to use reusable materials to collect menstrual blood compared with women in the poorest wealth quintile (p < 0.05). Also, women who were exposed to television (AOR = 0.78; 95% CI 0.61–0.99) had less odds of using reusable materials compared with women who were not exposed to television (p < 0.05). Conclusion: This study showed that the use of reusable menstrual materials was influenced by socio-demographic factors, economic factors and exposure to mass media. Therefore, policies and programmes aimed at promoting menstrual health should focus on less privileged women. The mass media presents an opportunity for communicating menstrual hygiene.

The use of rock phosphate and phosphate solubilising fungi (Aspergillus niger) to improve the growth and the yield of upland rice on typic Kandiudalf

Field experiment was conducted to study the effect of rock phosphate (RP) and phosphate solubilizing fungi application on upland rice yield intercropped with pigeon pea from 2009 to 2011 at the Agricultural Research Centre, Kade, University of Ghana. In the first year, the main plot treatment consisted of five levels of phosphate fertilizer viz. 0 kg/ha P2O5, 40 kg/ha P2O5 RP, 80 kg/ha P2O5 RP, 120 kg/ha P2O5 RP and 45 kg/ha P2O5-triple super phosphate (TSP), while the planting dates of pigeon pea was set up as subplot (40 DAS –pigeon pea planted 40 days after sowing rice seed and 80 DAS- pigeon pea planted 80 days after sowing rice). In the second year, phosphate fertilizer was the main plot treatment, consisting of (0 kg/ha P2O5, 45 kg/ha P2O5 RP, 90 kg/ha P2O5 RP and 45 kg/ha P2O5 TSP), and the subplot treatment was inoculated and uninoculated with phosphate solubilising fungi Aspergillus niger. The highest grain yield of 1.051 t/ha was obtained with the 120 kg P2O5 /ha RP followed by the 40 kg P2O5 /ha RP. Phosphate levels did not significantly influence the grain yield in the first year (p = 0.08) but planting pigeon pea as an intercrop at the different planting dates had a significant positive effect on both the grain and straw yields of rice (p = 0.016, .07). There was no significant interaction between the use of different phosphorus levels and the different planting dates of pigeon pea (p = 0.348). In the second year, phosphate levels had significant influence on grain yield (p = 0.014) and the highest grain and straw yields occurred where TSP and Aspergillus niger were used to plant rice. Inoculating rice with or without Aspergillus niger had no significant influence on grain yields (p = 0.447). No significant interaction existed between phosphate levels and level of inoculation (p = 0.206). The use of TSP and Aspergillus niger to grow rice improved rice yield followed by 45 kg P2O5/ha RP + Inoculation.

Use of Sentinel-l and Sentinel-2 for Monitoring Illegal Fishing Off Ghana

An efficient and inexpensive service has been developed for the monitoring of fishing vessels in West Africa using Earth Observation (EO) data. The service makes use of fast- delivery data from the Synthetic Aperture Radar (SAR) instrument on Sentinel-1 and the Multi Spectral Imager (MSI) on Sentinel-2, detecting objects that differ markedly from their immediate background using a constant false alarm rate (CFAR) test. The selected objects are then discounted from further analysis if they fall within the bespoke land mask or can be shown from time series analysis to be static (signals associated with jetties, oil platforms and "ghost objects" arising from very bright land targets). Detections are matched to, and verified by, AIS data, which provides location and dimensions of ships that are legally in the region. Both matched and un-matched data are then displayed on a web portal for use by the Gulf of Guinea (GoG) state authorities.

Use of service data to inform pediatric HIV-free survival following prevention of mother-to-child transmission programs in rural Malawi

Background: Recent years have seen rapid and significant progress in science and implementation of programs to prevent mother-to-child transmission of HIV. Programs that support PMTCT routinely monitor service provision but very few have measured their effectiveness. The objective of the study was to use service data to inform HIV-free survival among HIV exposed children that received antiretroviral drugs to prevent mother-to-child transmission (PMTCT) of HIV. The study was conducted in two rural districts in Malawi with support from FHI 360. Methods: A descriptive observational study of PMTCT outcomes was conducted between June 2005 and June 2009. The dataset included patient-level data of all pregnant women 1) that tested HIV-positive, 2) that were dispensed with antiretroviral prophylaxis, and 3) whose addresses were available for home visits. The data were matched to each woman’s corresponding antenatal clinic data from home visit registers. Results: Out of 438 children whose home addresses were available, 33 (8%) were lost to follow-up, 35 (8%) were alive but not tested for HIV by the time home visit was conducted, and 52 (12%) were confirmed deceased. A total of 318 children were alive at the time of the home visit and had an HIV antibody test done at median age 15 months. The resulting estimated 24-month probability of HIV-free survival over all children was 78%. Among children who did not receive nevirapine, the estimated 24-month probability of HIV-free survival was 61%, and among those who did receive NVP syrup the estimate was 82%. Conclusions: When mothers and newborns received nevirapine, the estimated 24-month probability of HIV-free survival among children was high at 82% (CI: 54% to 99%). However this conclusion should be interpreted cautiously 1) due to the wide confidence interval; and 2) because the confidence interval range includes 55%, which is the natural HIV-free survival rate in the absence of a PMTCT intervention. This analysis highlighted the need of quality data and well-structured home visits to assess PMTCT effectiveness.
