Background: This study aimed to assess the level of knowledge, attitudes, and practice of solid waste disposal among residents of the Husuren-Kwari community in Kano, Nigeria.Methods: A non-experimental descriptive survey research design was adopted and data were obtained from June to October 2019. A simple random sampling technique was used to select 45 households as the samples. The data was collected using a semi-structured questionnaire. The data obtained were analyzed using a statistical package for social sciences software.Results: In this study, more than half (53.3%) of the respondents were ≥36 years and 80.0% of them were males. About 42.2% of the respondents had a secondary level of education and 44.4% of the respondents were farmers. Close nine-tenths (88.9%) of the respondents agreed that proper waste disposal is any means that we can get rid of unwanted materials and 84.4% know the local method of disposing of waste. Only 24.4% of the respondents were aware of the modern methods of solid waste disposal. Little above half (51.1%) of the respondents were using the burning method to dispose of the waste, and close to half (46.7%) of the respondents were dumping the waste in front of the house.Conclusions: The finding reported a poor level of knowledge, negative attitude, and poor level of practice regarding waste disposal among the people of this community. The government and non-governmental organizations should organize a massive campaign on the importance of proper waste disposal and to create awareness on proper waste disposal practices.

<p class="abstract"><strong>Background:</strong> Many studies across the globe have reported the prevalence of low back pain (LBP) among office workers. This study aimed to find out the prevalence of LBP and associated factors among office workers in Kano city, Nigeria.</p><p class="abstract"><strong>Methods:</strong> A cross-sectional type of study was conducted among the office workers in Kano metropolitan from September to December 2019. A total of 300 office workers were selected using a convenience sampling technique. The data was collected from the respondents by face-to-face interview technique using a semi-structured questionnaire and all the data collected were analyzed using statistical software (SPSS version 22.0).</p><p class="abstract"><strong>Results:</strong> In this study, the mean age of the respondents was 38.6±9.6 years and 72.7% of them were male.

Background: Drugs and substance abuse is one of the commonest emerging public health problems among both adults and adolescents in developing countries. This study aimed to assess the level of knowledge and prevalence of drugs and substance abuse among the students of a selected tertiary health institution in Kano, Nigeria.Methods: A multistage sampling technique was used during selection of the participants and the study was conducted for a period of 4 months (July to November, 2019). A total of 151 students from school of health technology Kano, Nigeria were recruited and the data was collected using a self-administered semi-structured questionnaire. Data was analyzed by the use of statistical software (SPSS version 20.0) and the results were presented in the form of figures and tables with frequencies and percentage. In addition, a statistical test of significance (x2 test) was applied to determine the significant associations between variables, p≤0.05 was considered statistically significant.Results: The mean age of study participants was 27.2±6.3 years and majority of them (64.2%) were between 20-25 years. More than nine-tenths (94.0%) of the respondents were Hausa/Fulani, and 32.5% of the respondents were SCHEW students. Little above half (53.6%) of the respondents were earning less than 11000 naira per month and 62.3% of the respondents sourced the information regarding drugs and substance abuse from their friends. All the respondents have seen cigarettes before and 57.6% have seen inhalants (such as glue, petrol etc). Regarding the reason for substance/drug abuse; about 68.9% stated that it’s an addiction and based to the factors enhancing drugs and substance abuse; 72.7% mentioned that it was due to peer pressure, and 72.2% mentioned unemployment. Based on societal factors that promotes drugs and substance abuse; more than three-fifths (64.9%) mentioned that it was reluctant attitude of people and 20.5% mentioned it was some cultural factors.Conclusions: The prevalence of drug and substance abuse was 18.5%. Nevertheless more than three-fifths of them had good level of knowledge regarding drug and substance abuse. The ethnicity of the respondents was found significantly associated with level of knowledge regarding drug and substance abuse. There is need for more focused attention by parents, teachers, government and general public on the problem of drug and substance use.

<p class="abstract"><strong>Background:</strong> Groundnut (<em>Arachis hypogea </em>L.) also known as peanut is one of the world’s principal oilseed crop. The plant originated in South America, but is widely distributed throughout the tropic and warm temperate areas in Asia, Africa, Oceania, North and South America and Europe. This study aimed to evaluate the proximate content of some genotype of groundnut (<em>Arachis hypogea </em>L.).</p><p class="abstract"><strong>Methods:</strong> A total of<strong> </strong>four different groundnut varieties were used in this study; the varieties were obtained from international crop research institute for the semi-arid tropic (ICRISAT) Kano station. Samples selected were Samaru nut 11 (Samnut-11); Samaru nut 22 (Samnut-22); Samaru nut 23 (Samnut-23); and Samaru nut 24 (Samnut-24). The analysis was conducted in the animal laboratory faculty of Agricultural sciences, in Bayero University Kano, Nigeria. The moisture, ash, crude protein, crude fat, crude fiber and nitrogen free extract of the samples were detected using a standard procedure adapted from official methods of analysis 1990. Data was analyzed using the analysis of variance (ANOVA) and means were separated using Student-Newman-Keuls (SNK) in SAS version 9.3.  </p><p class="abstract"><strong>Results:</strong> The higher content of ash was found in Samnut-24 (4.4%), and Samnut-23 (11.8%) was found to have highest moisture. Samnut-23 has the highest content of crude protein (30.6%) and crude fiber (4.7%). A higher content of fat and oil (ether extraction) was found in Samnut-23 (40.0%) and a higher content of soluble carbohydrate (NFE) was found in Samnut-11(27.4%) and Samnut-22 (27.4%).</p><p class="abstract"><strong>Conclusions:</strong> Groundnut characteristically contained high level of oil and protein with low level of moisture, ash and carbohydrate; this makes it a potential source of edible-oil. The high protein of the defatted groundnut makes it good as cake for human consumption and useful as animal feeds. Samnut-23 has enriched edible-oil content and the crude protein, while Samnut-22 has low oil content and protein, but has enriched with NFE. Based on the conclusion it was recommended that further research should be carried out on the quality of proximate content of groundnut between the four varieties.</p>
