Food product prices and its implications for food security in Nigeria

The study examined the prices of food products and its implications for food security in Nigeria. Data was obtained from Federal Office of Statistics and was analyzed using histogram and and price index number (Laspyres index). The study show that food price inflation is caused by frequent hike in the prices of petroleum products coupled with poor performance of the agricultural sector. Between 1996 to 2002, fuel official price rose by 136 percent and is accompanied with higher price index values in the food component of the annual average composite consumer price index. A similar phenomenon is observed between 2003 and 2005. The study further revealed that it is the poverty syndrome occasioned by a lack of purchasing power coupled with food price inflation that renders the populace vulnerable to food insecurity.. Food insecure households face a significant risk of food consumption falling below a critical level with regards to health and survival. A rise in the price of food does not necessarily raise incomes of food producers. This may not induce a downward shift in the supply curve in the long run. The study recommends providing poor (food insecure) people with opportunities to earn adequate incomes, ensuring abundant food supply from domestic production, adequately maintained rural feeder roads, banning of motor park touts, halting of police extortion at check points and provision of cheap and adequate supply of fuel

X-ray Equipments and Accessories as possible Vectors of Nosocomial Bacteria in Anambra State, Nigeria.

Background of Study: Nosocomial infections have become a major challenge in health institutions, as they affect the quality of health care delivered. The radiology department is one of the mainstays of modern medicine. It is therefore necessary to assess its role in the spread of nosocomial infections.Aim: To assess the presence and specie of nosocomial bacteria on x-ray equipments and accessories as well as their prevalence in public and private hospitals in Anambra state.Method: Sterile swab sticks were used daily to swab the surfaces of selected x-ray equipments and accessories, at the close of work in public and private hospitals in Anambra State. MacConkey and Blood agar media were used to prepare the culture media. The prepared media were put in petri dishes andswab samples were inoculated onto the culture plates. Culture plates were then incubated for 24 hours, at a temperature of 37oc. Bacterial identification was done microscopically under bright light based on their colonial characteristics.Results: Bacteria were isolated in 43/50 (86%) samples collected. Bacteria isolated were; Staphylococcus aureus (36.1%), Pseudomonas aeruginosa (22.7%), Proteus spp (7. 2%), Streptococcus (13. 4%), and Coliform spp. (20.6%). X-ray cassettes had the highest bacterial load followed by X-ray tube handles and couch.Conclusion: Radiology equipment and accessories in Anambra State have high bacterial load and therefore are potential sources of nosocomial infection

Economic Efficiency of Processed Hibiscus Sabdanriffa (Roselle) Drink in Imo State, Nigeria

The study developed a model to evaluate efficiencies of Zobo drink processors in Imo State using Data Envelopment Analysis (DEA). Data were collected from 163 Zobo drink processors across 36 markets in the study area and was analyzed under the constant returns to scale (CRTS) and variable returns to scale (VRTS) assumptions. Result showed that Zobo processing was highly profitable with about 44.34% net margin on total revenue generated. Mean economic efficiency scores estimated from the DEA frontier for both CRTS and VRTS were 0.537 and 0.683. Sex, educational level and alternative to income were most statistically significant factors. It was recommended that more male involvements are encouraged in Zobo drink; educated individuals particularly unemployed are advised to engage and create a cliché for themselves through the use of more innovative processing and packaging activities and adopting cost-minimizing input mixes of best-practice to enable them become fully efficient

Performance of oyster mushroom (Pleurotus ostreatus) in different local agricultural waste materials

The present study was conducted to evaluate different substrates for establishment of yield performance of oyster mushroom (Pleurotus ostreatus). The substrates were prepared from single or mixture of different agricultural waste materials supplemented with lime and water as additive to each substrate. A total of eight substrates labeled 1 to 8 were prepared. Substrate 4, which is a mixture of palm kernel cake and maize cob, had the highest mycelia growth rate (80%), sprouted 15 days after inoculation and yielded the highest total fresh weight for a period of 10 harvests (2957.5 g). Substrate 3, a mixture of palm kernel cake and sawdust, had 78% mycelia growth rate, sprouted 16 days after inoculation and yielded 2535.7 g fresh mushroom. Substrate 2 is a mixture of maize straw and sawdust and had 75% mycelia growth rate, sprouted 17 days after inoculation and a total of 2207.4 g fresh weight. The mushroom grown in substrates 4, 3 and 2 produced bigger and firmer fruiting bodies, which differed significantly (P < 0.05) from the other substrates. Substrates 1 and 5 which had 50% mycelia growth rate, sprouted 31 and 33 days after inoculation and 1408.8 and 1092.6 g, respectively, were recorded after a period of 10 harvests. Substrate 4, 3 or 2 is therefore recommended for cultivation of oyster mushroom.Keywords: Oyster mushroom (Pleurotus ostreatus), mycelial growth, palm kernel cake (PKC), substrate, maturit

Prevalence and burden of HBV co-infection among people living with HIV:A global systematic review and meta-analysis

Globally, in 2017 35 million people were living with HIV (PLHIV) and 257 million had chronic HBV infection (HBsAg positive). The extent of HIV-HBsAg co-infection is unknown. We undertook a systematic review to estimate the global burden of HBsAg co-infection in PLHIV. We searched MEDLINE, Embase and other databases for published studies (2002-2018) measuring prevalence of HBsAg among PLHIV. The review was registered with PROSPERO (#CRD42019123388). Populations were categorized by HIV-exposure category. The global burden of co-infection was estimated by applying regional co-infection prevalence estimates to UNAIDS estimates of PLHIV. We conducted a meta-analysis to estimate the odds of HBsAg among PLHIV compared to HIV-negative individuals. We identified 506 estimates (475 studies) of HIV-HBsAg co-infection prevalence from 80/195 (41.0%) countries. Globally, the prevalence of HIV-HBsAg co-infection is 7.6% (IQR 5.6%-12.1%) in PLHIV, or 2.7 million HIV-HBsAg co-infections (IQR 2.0-4.2). The greatest burden (69% of cases; 1.9 million) is in sub-Saharan Africa. Globally, there was little difference in prevalence of HIV-HBsAg co-infection by population group (approximately 6%-7%), but it was slightly higher among people who inject drugs (11.8% IQR 6.0%-16.9%). Odds of HBsAg infection were 1.4 times higher among PLHIV compared to HIV-negative individuals. There is therefore, a high global burden of HIV-HBsAg co-infection, especially in sub-Saharan Africa. Key prevention strategies include infant HBV vaccination, including a timely birth-dose. Findings also highlight the importance of targeting PLHIV, especially high-risk groups for testing, catch-up HBV vaccination and other preventative interventions. The global scale-up of antiretroviral therapy (ART) for PLHIV using a tenofovir-based ART regimen provides an opportunity to simultaneously treat those with HBV co-infection, and in pregnant women to also reduce mother-to-child transmission of HBV alongside HIV

Brucellosis as an Emerging Threat in Developing Economies:Lessons from Nigeria

Nigeria is the most populous country in Africa, has a large proportion of the world's poor livestock keepers, and is a hotspot for neglected zoonoses. A review of the 127 accessible publications on brucellosis in Nigeria reveals only scant and fragmented evidence on its spatial and temporal distribution in different epidemiological contexts. The few bacteriological studies conducted demonstrate the existence of Brucella abortus in cattle and sheep, but evidence for B. melitensis in small ruminants is dated and unclear. The bulk of the evidence consists of seroprevalence studies, but test standardization and validation are not always adequately described, and misinterpretations exist with regard to sensitivity and/or specificity and ability to identify the infecting Brucella species. Despite this, early studies suggest that although brucellosis was endemic in extensive nomadic systems, seroprevalence was low, and brucellosis was not perceived as a real burden; recent studies, however, may reflect a changing trend. Concerning human brucellosis, no studies have identified the Brucella species and most reports provide only serological evidence of contact with Brucella in the classical risk groups; some suggest brucellosis misdiagnoses as malaria or other febrile conditions. The investigation of a severe outbreak that occurred in the late 1970s describes the emergence of animal and human disease caused by the settling of previously nomadic populations during the Sahelian drought. There appears to be an increasing risk of re-emergence of brucellosis in sub-Saharan Africa, as a result of the co-existence of pastoralist movements and the increase of intensive management resulting from growing urbanization and food demand. Highly contagious zoonoses like brucellosis pose a threat with far-reaching social and political consequences
