    A comprehensive study on the effect of processing on fatty acid and phospholipid compositions of Brachystegia eurycoma seed flour was conducted. Processing methods (boiling, fermentation and roasting) were adopted using standard analytical techniques. The most concentrated fatty acids (%) were linoleic acid (47.95 – 50.91) > oleic acid (26.51 – 30.91) > palmitic acid (11.51 – 14.16) > stearic acid (3.06 – 5.54). Lenoceric, erucic, and arachidic acids were present with none of them recording up to 1% while caprylic, capric and margaric acids were not at the detection limit of GC. All the processing methods increased the contents of palmitic, palmitoleic, linoleic and linolenic acids. The oleic acid content was reduced in boiled, fermented and roasted samples by 60.93, 59.97 and 63.77%, respectively. The phospholipid analysis gave result (%) of phosphatidic > phosphatidylinositol > phospatidyserine > phosphatidyethanolamine concentrations. Generally, the processing methods showed deviations in fatty acid and phospholipid components from the raw seeds. There was a clear indication that the raw and processed samples of B. eurycoma seed oils contained a high level of polyunsaturated fatty acids, making them a healthy low fat food.

    The traditional and screw press techniques were adopted and utilized extensively by Nigerian honey producers and these have led to the absence of a good quality and timely produced honey devoid of foreign materials and marketable by international standard. Ample information from literature survey showed that the Langstroth hive which is beyond the reach of common Nigerian bee farmer due to its high cost. A 750 W indigenous centrifugal honey extractor was developed using locally sourced materials.. The machine was tested at extraction speed levels of 272, 287, 351, 1445, 1730, 2300 and 2575 rpm. Quantifiable extractions were obtained at all speed levels except at a speed of 2575 rpm where a vicious crushed extract of honey and comb was observed. High speed extraction was not favorable as it resulted in the destruction of the honey comb. Honey extracted at the two lower speeds of 272 and 287 rpm were found to be purer with less foreign materials and of high quality.  This indigenous centrifugal honey extractor is also favorable for extraction of honey from other types of hives apart from the Langstroth hive and is marketable

    Inaccessibility to information could hinder the adoption of dry season agriculture which is very significant to ending the spate of food insecurity in Nigeria. This cross-sectional survey examined access to broadcast media agricultural content and the effect of such information on dry season agriculture practice among smallholder farmers in Nigeria’s Federal Capital Territory (FCT). Participants consisted of 381 smallholder farmers selected from rural settlements in Kuje and Kwali Area councils, through a multi-stage sampling procedure. Data for the study was generated via a self-designed questionnaire. The findings of this study show that access to the broadcast media agricultural content is high (94.2%) in the FCT and the majority (83.1%) of the farmers are particularly exposed to agricultural programmes on dry season farming. However, the regularity of exposure to such programmes is considered rare/occasional by a sizable proportion (44.8%) of the selected farmers. The research further confirms the general acceptability of the broadcast programmes on dry season agriculture but the major snag is that the majority (>50%) of the farmers think that the time at which the information is broadcast is inappropriate. In terms of the practical implications of the programmes, findings also revealed that 50%) remain adamant that dry-season farming is not achievable and productive; therefore, they have not engaged in dry season irrigation agriculture. We concluded that the knowledge gained from the dry season agricultural programmes in the broadcast media is not sufficient for farmers to successfully engage in dry season irrigation farming. The study recommends a long-term and sustained media campaign on dry season farming, the use of interactive programme content, and rescheduling agricultural programmes to farmers’ preferred time could yield the desired impact on dry season irrigation farming and food security in Nigeria

    Children with nasal foreign bodies are commonly seen in everyday practice. The aim of this study was to document the pattern of foreign bodies in the nose, their treatment and outcome. Methods. This was a prospective audit of all children seen in the ear, nose and throat clinic, accident and emergency unit and emergency paediatric unit at the University of Ilorin Teaching Hospital, Nigeria, from August 2005 to July 2006. Results. Of a total of 173 patients with ear, nose and throat foreign bodies seen during the study period, 71 patients had foreign bodies in the nose. The male/female ratio was 1.5:1 and the mean age was 2.5 years (range 1 - 15 years), under-5s comprising 72% of the patients. The most common foreign bodies were grains and seeds (35%). Presentation was within 24 hours in 45% of cases, between 1 and 5 days in 27%, and longer in the rest. Of the patients 51% had inserted the foreign body into the nose themselves, and in 39% of cases this had happened at school. In most cases (68%) the foreign body had been inserted into the right nostril. Most children had an offensive nasal discharge (45%) or were asymptomatic (27%). Parents were the first to make the diagnosis in 63% of cases, and in 32% of cases removal had been attempted before presentation. Most of the foreign bodies (89%) were mechanically extracted with a Jobson-Horne probe. In 61% of cases removal was done by a senior registrar. General anaesthesia was needed in a minority of cases. Minimal epistaxis after removal occurred in 50.7%, and only 1 patient had septal perforation. Conclusion. Nasal foreign bodies are still a challenge among under-5s. Public health education is needed to make parents and caregivers aware that it is hazardous for a child to insert a foreign body into the nose. Consistent with published guidelines, the majority of cases can be managed safely with direct extraction in the office setting. With adequate training, primary health care practitioners can manage most cases successfully and will know when to refer complicated ones

    Spatial Dispersion Modelling of Air Emissions from a Farm Using Gaussian Model

    Agricultural activities may cause significant air pollution at the local, regional, and global scales due to the uncontrolled release of pollutants into the environment. This study therefore provided model-based spatial estimates of ground-level concentrations of air emissions from Landmark University Farm. The emission inventory and meteorological parameters of the farm were used to execute a Gaussian dispersion model over a distance of 2 km. Elevated ground-level concentrations were recorded, which continued to decrease as the distances increased. These concentrations exceeded threshold limits stipulated by National Ambient Air Quality Standard. The study concluded that high levels of air emissions obtained in this study are indications of tendencies for possible violation of permissible limits at locations not too far from the University Farm

    Global and regional burden of disease and injury in 2016 arising from occupational exposures : a systematic analysis for the Global Burden of Disease Study 2016

    Objectives This study provides an overview of the influence of occupational risk factors on the global burden of disease as estimated by the occupational component of the Global Burden of Disease (GBD) 2016 study. Methods The GBD 2016 study estimated the burden in terms of deaths and disability-adjusted life years (DALYs) arising from the effects of occupational risk factors (carcinogens; asthmagens; particulate matter, gases and fumes (PMGF); secondhand smoke (SHS); noise; ergonomic risk factors for low back pain; risk factors for injury). A population attributable fraction (PAF) approach was used for most risk factors. Results In 2016, globally, an estimated 1.53 (95% uncertainty interval 1.39-1.68) million deaths and 76.1 (66.3-86.3) million DALYs were attributable to the included occupational risk factors, accounting for 2.8% of deaths and 3.2% of DALYs from all causes. Most deaths were attributable to PMGF, carcinogens (particularly asbestos), injury risk factors and SHS. Most DALYs were attributable to injury risk factors and ergonomic exposures. Men and persons 55 years or older were most affected. PAFs ranged from 26.8% for low back pain from ergonomic risk factors and 19.6% for hearing loss from noise to 3.4% for carcinogens. DALYs per capita were highest in Oceania, Southeast Asia and Central sub-Saharan Africa. On a per capita basis, between 1990 and 2016 there was an overall decrease of about 31% in deaths and 25% in DALYs. Conclusions Occupational exposures continue to cause an important health burden worldwide, justifying the need for ongoing prevention and control initiatives

    Mapping disparities in education across low- and middle-income countries

    Educational attainment is an important social determinant of maternal, newborn, and child health1–3. As a tool for promoting gender equity, it has gained increasing traction in popular media, international aid strategies, and global agenda-setting4–6. The global health agenda is increasingly focused on evidence of precision public health, which illustrates the subnational distribution of disease and illness7,8; however, an agenda focused on future equity must integrate comparable evidence on the distribution of social determinants of health9–11. Here we expand on the available precision SDG evidence by estimating the subnational distribution of educational attainment, including the proportions of individuals who have completed key levels of schooling, across all low- and middle-income countries from 2000 to 2017. Previous analyses have focused on geographical disparities in average attainment across Africa or for specific countries, but—to our knowledge—no analysis has examined the subnational proportions of individuals who completed specific levels of education across all low- and middle-income countries12–14. By geolocating subnational data for more than 184 million person-years across 528 data sources, we precisely identify inequalities across geography as well as within populations
