Background
The Novel Corona virus SARS-CoV-2 emerged to affect the human population in 2019 causing COVID-19 pandemic. The only preventive measures available are social distancing, hand washing and face masks. This study aims to assess the knowledge, attitude and practice of the Sudanese people towards COVID-19.
Methods
An online cross-sectional study targeting adult Sudanese people was conducted in April 2020. The study used a self-administered questionnaire containing 18 knowledge questions, 5 questions for attitude and six questions for practices. Social media such as Facebook and WhatsApp were utilized to disseminate the questionnaire. The total number of eligible questionnaires available for analysis by the end of the period was 987.
Results
The mean (±SD) age of respondents was 30.13 (±9.84) years with males representing 55.4%. The majority were university and higher education levels (95.2%), residing in Khartoum (71.7%). The mean (±SD) knowledge score of the participants was 15.33 (± 2.24) and was found to be associated with education level and age groups (p-value = 0.022, P value =0.010) respectively. The mean (±SD) attitude score was 04.15 (± 0.97) and was significantly associated with older groups and better-educated participants (p-value =0.001, p-value = 0.048) respectively. The practices related to COVID-19 preventive measures mean (±SD) was 02.58 (± 1.73) with a significant difference between age groups and area of residence.
Conclusions
This study showed that the participants had good knowledge and satisfactory attitude that was not similarly expressed into practice. Efforts are needed in health education and law enforcement to improve the practices among all groups with special emphasis on younger and less educated males.
Field experiments were conducted for two consecutive summer seasons; 2005/06 and 2006/07, at Dongola area-Northern State (Sudan). The objectives were to investigate the effect of irrigation regimes; irrigation water amounts and irrigation intervals, on maize (Zea mays L.) growth and yield in addition to their effect on the soil moisture content. Irrigation water amounts were determined using FAO Penman-Monteith equation (1998) for estimating crop evapotranspiration (ET c ). Three levels of ET c were used; 100%, 75%, and 50% ET c . Three irrigation intervals were imposed; 10, 15, and 20 days. The application of irrigation treatments was started at the third irrigation. The results indicated that maximum plant population and field water use efficiency were obtained at irrigation water amount of 50% ET c in both seasons. Also, 10 days irrigation interval gave the highest values of plant height, cob length, 100-seed weight, grain yield, stover yield, and field water use efficiency.
The main objective of this work was to study the effect of sulphur application and irrigation water quality on some soil properties of the calcareous, alluvial and sandy soils. A lysimeter experiment was conducted and filled with calcareous, alluvial and sandy soils to evaluate the impact of using elemental sulfur on the yields and mineral uptake of wheat plant. The experiment was cultivated with wheat plant (Triticum Vulgare L.), and irrigated by saline water (diluted sea water recording EC values of 2000, 3000 and 4000 mgl-1). The rate of sulfur applications were 0, 476 and 952 kg Sha-1. The results showed that increasing salinity to 4000 mgl-1 gradually and significantly decreased the fresh and dry weights of wheat were as follow: Sandy > alluvial > calcareous soils, and the reductions in the grain yield under the same condition were 27, 15 and 23% relative to the control for calcareous, alluvial and sandy soils, respectively. Salinity levels also significantly reduced the total uptake of NPK of all crops cultivated in different soils under study. Under sulfur application, the fresh and dry weights of wheat significantly increased relative to the control treatment. Under high salinity level 4000 ppm and high rate of sulfur (952 kg Sha-1), the increment in the crop under study and cultivated in calcareous, alluvial and sandy soils were 74, 60 and 46% for wheat grain yield, relative to the control, respectively. Also, sulfur applications significantly increased total uptake of NPK of wheat crop cultivated in different soils, especially calcareous soil. The chemical composition of soils under study after cropping showed that each of electrical conductivity (EC), sodium adsorption ratio (SAR) and soil pH increased with increasing salinity levels in the irrigation water, while, sulfur application decreased each of EC and pH and reduced SAR.
Background
Dispensing antibiotics without prescription (DAwP) is a widespread practice, especially in developing countries, contributing to antibiotic resistance. Community pharmacists play a significant role in promoting rational use of antibiotics by refraining from DAwP, and providing drug information to patients. This study aimed to evaluate community pharmacists’ knowledge, attitude and practice, and to assess the factors behind DAwP.
Methods
A cross-sectional study was conducted in 2020 among random sample of community pharmacists in Sudan. Online semi-structured questionnaire was used for data collection. The association between dependent and independent variables was assessed using Chi-square test; a
P
-value less than 0.05 was considered significant.
Results
Of the 1217 pharmacists who participated, the majority were female (n = 645, 53%). Most pharmacists have a B. Pharm degree (n = 1026, 84%) and less than 5 years’ experience (n = 718, 59%). Notably, the majority of community pharmacists have good knowledge (n = 735, 61.7%), which is significantly associated with years of experience (P < 0.00). More than half (n = 623, 52.2%) of the pharmacists have above average score of practice. Nearly all the pharmacists who participated have a positive attitude in relation to DAwP (n = 1204, 98.9%). More than half of the pharmacists were DAwP for tonsillitis (n = 817, 67%), wound infection (n = 766, 62.9%), and urinary tract infection (n = 664, 54%). The leading factor behind DAwP was the low socioeconomic status of the patients (n = 624, 51%). Additionally, 47% of the pharmacists (n = 572) thought that they were knowledgeable enough to DAwP.
Conclusion
Despite their positive attitude and average level of knowledge regarding DAwP, Sudanese community pharmacists frequently are DAwP for tonsillitis. Low patients’ socioeconomic status was the leading factor behind DAwP. Accordingly, extensive work from health authorities to improve the accessibility and affordability of the health system as well as the development of an antibiotic stewardship program are required to diminish DAwP.
