Liquid and semi-solid culture media are used to maintain and proliferate bacteria, fungi, and Oomycetes for research in microbiology and plant pathology. In this study, a comparison was made between soybean milk medium, also referred to as soymilk, and media traditionally used for culturing soybean pathogens to determine if soymilk medium was an effective medium for growth of Colletotrichum truncatum, Fusarium virguliforme, Macrophomina phaseolina, Passalora sojina, Phomopsis longicolla, Phytophthora sojae, Pythium irregulare, Rhizoctonia solani, and Sclerotinia sclerotiorum. Based on radial mycelial colony growth rates, C. sojina grew significantly (P < 0.05) faster on soymilk dextrose agar (SDA) than on V-8 agar, and C. truncatum and F. virguliforme grew significantly (P < 0.05) faster on SDA than potato dextrose agar (PDA). Significantly (P S. sclerotiorum grown on SDA as compared to PDA. Soymilk used with agar or used alone as a broth may be an option for replacing more expensive processed culture media.

The purpose of this study was to determine nurse’s knowledge, attitude and practice on the initial management of acute poisoning among adult casualties seen at Accident and Emergency Department (AED), Kenyatta National Hospital (KNH). The study was cross sectional. Both qualitative and quantitative methods of data collection were employed. The target population were all nurses working at AED, KNH. Purposive sampling was used to select study subjects. Sample size included all Accident and Emergency (A&E) nurses who met subject’s inclusion criteria. Structured questionnaires, observation checklist and interview were used to collect the data. Sixty eight (82%) of A&E nurses participated in this study. The study found out that with higher nursing qualification and training on courses related to emergency care, knowledge and skills of A&E nurses on the initial management of acute poisoning is enhanced. A&E nurses with lower education level had a higher mean score of positive attitude compared with nurses with higher nursing qualification. Majority 60 (88.2%) of the A&E nurses indicated that, they required more training on the initial management of acute poisoning. Study recommends that A&E nurses should be trained on various types of poisoning including;assessment, clinical presentations and management to include gut decontaminations. In addition, refresher courses should be organised for those already trained. Flowcharts that will enhance easy identification and management of poisoned casualties should be put in place and utilized accordingly.

Wasting has been observed as a common feature of the human immunodeficiency virus (HIV) disease since the first reports and its presence increases the risk of death. There is no consensus on how to manage wasting associated with HIV. The goal of this study was to assess the effectiveness of a locally made Chickpea Sesame Based RUTF (CS-RUTF) in treating wasting associated with HIV in developing countries. Chronically sick adults from Mangochi Health District (Malawi) with wasting and confirmed or presumptive clinical diagnosis of HIV were recruited for the study. Subjects received a daily ration of 500 grams of CS-RUTF for 3 to 5 months. Nutrition status changes and mortality were used to assess the effectiveness of the intervention. There were 3 patterns of anthropometric responses continuous weight gain (WG), static weight (SW) and continuation weight loss (WL). The distribution of the 3 patterns is 53.9% (82/154) for the WG pattern, 9.1% (14/154) for the SW pattern and 37.0% (57/154) for the WL pattern. For the WG pattern, the overall median weight gain was 4.6 (2.4 to 7.1) kg. It was 5.7 (3.5 to 7.8) kg for those who completed 3 months of sup-plementation. MUAC and BMI changes followed similar pattern than weight change. Not being on HAART, acute diarrhoea during follow up, episode of reduced appetite during follow up, missing at least one visit were identified as risk factors for intervention failure. Overall, 38.5% (72/187) of study participants died during the intervention. In conclusion, despite that the study confirms the limited impact of food based interventions on mortality among wasted HIV positive individuals, it also suggests that supplementation with CS-RUTF may be an effective intervention for reversing wasting associated with HIV if combined with HAART and specific treatment of severe opportunistic infection causing diarrhoea and reducing appetite.

Severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) has been a global threat spreading in Sierra Leone, and many studies are being conducted using various Statistical models to predict the probable evolution of this pandemic. In this paper, we use the autoregressive integrated moving average (ARIMA) model with the aim of forecasting the cumulative confirmed cases of SARS CoV-2 in Sierra Leone. The Akaike Information Criterion (AIC) was applied to the training data as a criterion method to select the best model. In addition, the statistical measure RMSE and MAPE were utilized for testing this data, and the model with the minimum RMSE and MAPE was selected for future forecasting. ARIMA (3, 2, 1) was confirmed to be the optimal model based on the lowest AIC value. This model was then applied to study the trend of SARS CoV-2 from 1st February 2022 to 30th February 2022. The result shows that incidence of SARS CoV-2 from 1st February 2022 to 30th February 2022, increasing growth steep in Sierra Leone (7718.629, 95% confidence limit of 6785.985 - 8651.274).

使用在长期研究橙腹田鼠的社会组织中收集的数据 ,我们研究了该物种配对的形成和解体。大多数在春季形成的配对包括了各公社群 (包括至少两个同性个体的群 )过冬后的生存者。无论雌、雄个体是否来自相同或不同的的公社群 ,配对的个体都不是同一家庭的成员。春秋季形成的新配对 ,通常包括一直在研究地游荡的无亲缘关系的个体。所以 ,我们的野外数据表明 ,橙腹田鼠避免与家庭成员配对 ;但是没证据表明自由生活的橙腹田鼠以体重为基础来进行配偶选择 ,也没证据表明在野外或半自然的实验室条件下 ,雌性个体偏好有性经历的雄性个体。在我们研究的种群中 ,配对分离的个体都具有一个特征 ,即分离前的繁殖成功率比未分离的配对个体低。在任何特定的时间内 ,由于雌、雄性个体的潜在配偶的数量有限 ,所以 ,几乎没有个体有机会同时比较两个或更多潜在配偶的特征。结果表明 :我们所研究的种群中的配对是机会主义式的。

Patients undergoing Magnetic Resonance Imaging (MRI) are exposed to strong, non-uniform static magnetic fields outside of the central imaging region, in which the movement of the body may induce electric currents in tissues which could possibly be harmful. The purpose of this study was to re-evaluate existing clinical protocols by determining the induced electromagnetic (EM) fields in MRI spine examinations. The study covered 120 MRI spine examinations at the MRI Unit of a hospital in Accra, Ghana. A numerical model based on Faraday’s equation was developed using the finite difference method (FDM) and MATLAB software to compute, first, a test simulation of induced EM field intensities and then actual measurements of induced fields on the spine. The simulation results were peak induced electric field, 0.39 V/m and current density, 0.039 A/m2. Patient results were;calculated maximum velocity, 0.29 m/s;peak induced electric field strength, 0.44 V/m, and current density, 0.043 A/m2. The levels of induced EM-fields were such that they would not pose any potential health hazards to the patients as these values were well below the recommended guidance levels set by the Directive IEC 60601-2-33 of the European Parliament.
