EFFECTS OF THE SPECIAL RICE PROJECT ON QUALITY OF INPUTS USED FOR RICE PRODUCTION IN KWARA STATE, NIGERIA

The study was carried out in Edu and Patigi Local Government Areas of Kwara State. Through a two stage random sampling technique, 70 participants in Special Rice Project (SRP) were selected from 6 circles in Patigi Local Government Area (LGA) and another 32 participants were similarly selected from 3 extension circles in Edu LGA, making a total of 102 respondents. Data collected by means of interview schedule were subjected to descriptive, t-test and Pearson Correlation Statistics. The result of the study indicated that 86.7%, 91.3%, 90.3% of the participating farmers in SRP rated seed, her- bicide and fertilizer respectively, provided by SRP, to be of very good quality while 19.6%, 49% and 58.8% of them rated seed, herbicide and fertilizer used before they joined SRP to be of very good quality. Furthermore, the highest proportion of participants 90 (88.3%) produced 3 - 4 tonnes of paddy rice per hectare as opposed to 19 .6% of them who were able to produce 3-4 tonnes before SRP was implemented. Participants also recorded an average annual income of N338,700.00 (US$2,419.29) / annum, that is, US$6.63/day, as against N129,410.00 (US$9,24.4)/annum earned by them before SRP was implemented. Thus, participants earned about US$6.63/day, which is higher than poverty income level of US$2/day. The result of the t-test analysis indicated that a significant difference exists between the rice yield of participants before and after the introduction of SRP (t=4.537, p≤0.05). Also Pearson Correlation analysis shows positive, linear and significant relationship between quality of farm inputs used and yield of rice (r = 0.562, p≤ 0.05). Based on the evidence from the study, Special Rice Project has the potential to serve as a good channel of accessing quality farm inputs, increase farm yield and income of farmers and contribute to Millennium Development Goal of reducing poverty level by 2015. It is, therefore, recommended that the activities of SRP are expanded to reach all categories of farmers in the country

SOCIO ECONOMIC FACTORS INFLUENCING FARMERS’ KNOWLEDGE IN INTEGRATED AND NON - INTEGRATED FISH FARMING IN OGUN STATE, NIGERIA

The study examined socio economic factors influencing farmer’s knowledge of Integrated and Non – integrated fish farming in Ogun Sate, Nigeria. Multistage simple  random sampling techniques was used to select 133 non - integrated fish farmers (NIFF) and 216 integrated fish farmers (IFF) making a total of n = 349. Data were analysed using chi-square, and Pearson Product Moment Correlation. Results showed that 92.5% of NIFF were males compared with 90.7% IFF. Also, 96.8% of IFF and 79.7% of NIFF were married. The mean ages of sampled farmers were 44 years (NIFF) and 46 years (IFF) while the mean fish farming experiences were 4 years (NIFF) and 5 years (IFF). Also, 41.2%of the respondents had moderate level of knowledge. knowledge of fish farming had significant association with respondents sex (χ2 = 9.44, df = 2, p < 0.05), marital status (χ2 = 23.2, df = 4, p < 0.05), occupation (χ2 = 25.5, df = 8, p < 0.05), mode of involvement (χ2 = 17.1, df = 2, p < 0.05), interaction with friend and relatives (χ2= 14.0, df = 2, p < 0.05), radio/television (χ2 = 21.7, df = 2, p < 0.05) and internet usage (χ2 = 6.40, df = 2, p < 0.05). Correlation analyses showed significant relationship between farmers knowledge and age (r = 0.20, p < 0.05), fish farming experience (r = 0.17, p < 0.05), level of cosmopoliteness (r = 0.16, p < 0.05), livestock population capacity (r = 0.21, p < 0.05), fish production capacity (r = 0.36, p < 0.05), area of land cultivated (r = 0.55, p < 0.05) and production constraints (r = -0.00, p < 0.05).Â

Increasing the uptake of HIV testing to reduce undiagnosed infection and prevent transmission among black African communities living in England: Barriers to HIV testing

Globally, the HIV epidemic continues to have an impact on the lives of millions of people. In 2008, there were an estimated 83,000 people living with HIV (both diagnosed and undiagnosed), equivalent to 1.3 per 1000 population in the UK. In that same year, 7,798 people were newly diagnosed with HIV. The global epidemic is reflected in the UK; around 38% (2,790) of these newly diagnosed infections were among black Africans who acquired their HIV through heterosexual contact. It is thought that most (87%) of these infections among black Africans in the UK were acquired abroad, mainly in sub-Saharan Africa (Health Protection Agency 2009). Late diagnosis of HIV is defined as diagnosis taking place after anti-retroviral treatment would normally have begun, or when the person has an illness which defines them as having AIDS. It is the most important factor associated with HIVrelated disease and death in the UK and is a particular problem among black Africans. In 2007, over 40% of new diagnoses among black Africans were classified as ‘late’. HIV testing can help reduce transmission of the virus. People who find out they have HIV may change their sexual behaviour as a result of the diagnosis. A negative HIV test provides an opportunity for preventive education and advice and may also lead to changes in behaviour. Increasing the frequency of testing may result in earlier detection of HIV following infection - when it is most virulent - providing greater opportunity to reduce transmissio

Determining the likely place of HIV acquisition for migrants in Europe combining subject-specific information and biomarkers data

In most HIV-positive individuals, infection time is only known to lie between the time an individual started being at risk for HIV and diagnosis time. However, a more accurate estimate of infection time is very important in certain cases. For example, one of the objectives of the Advancing Migrant Access to Health Services in Europe (aMASE) study was to determine if HIV-positive migrants, diagnosed in Europe, were infected pre- or post-migration. We propose a method to derive subject-specific estimates of unknown infection times using information from HIV biomarkers' measurements, demographic, clinical, and behavioral data. We assume that CD4 cell count (CD4) and HIV-RNA viral load trends after HIV infection follow a bivariate linear mixed model. Using post-diagnosis CD4 and viral load measurements and applying the Bayes' rule, we derived the posterior distribution of the HIV infection time, whereas the prior distribution was informed by AIDS status at diagnosis and behavioral data. Parameters of the CD4-viral load and time-to-AIDS models were estimated using data from a large study of individuals with known HIV infection times (CASCADE). Simulations showed substantial predictive ability (e.g. 84% of the infections were correctly classified as pre- or post-migration). Application to the aMASE study ( n = 2009) showed that 47% of African migrants and 67% to 72% of migrants from other regions were most likely infected post-migration. Applying a Bayesian method based on bivariate modeling of CD4 and viral load, and subject-specific information, we found that the majority of HIV-positive migrants in aMASE were most likely infected after their migration to Europe

Review of effectiveness and cost effectiveness: Increasing the uptake of HIV testing to reduce undiagnosed infection and prevent transmission among black African communities living in England

Usage of Purchased Self-tests for Hiv Infections Among Migrants Living in the Uk, France and the Netherlands: a Cross-sectional Study

OBJECTIVES: Self-tests are performed and interpreted autonomously by a person without involving a healthcare professional or a certified laboratory. To gain insight into the usage of purchased HIV self-tests (HIVST) among migrants living in high-income countries, we studied the prevalence and determinants of HIVST usage among migrants living in the UK, France and the Netherlands. METHODS: We used web-based questionnaire data collected between April 2014 and July 2015 among migrants living in the UK, France and the Netherlands who participated in the cross-sectional community survey of the aMASE (advancing Migrant Access to health Services in Europe) study. HIVST usage in the preceding 12 months and the corresponding 95% CIs were calculated. Using univariate logistic regression analyses, determinants of HIVST usage were evaluated. RESULTS: Among 477 migrants living in the UK (n=235), France (n=98) and the Netherlands (n=144), HIVST usage in the preceding 12 months was 1.89% (9/477, 95% CI 0.66% to 3.11%). As all nine HIVST users were men who have sex with men (MSM), we restricted our univariate analyses to MSM (n=240). HIVST usage was borderline significantly lower among MSM living in France and the Netherlands compared with those living in the UK (UK: reference; France: OR 0.20, 95% CI 0.03 to 1.14; the Netherlands: OR 0.06, 95% CI 0.00 to 1.05). Age, region of birth, educational level, registration at a general practitioner, recent number of male sexual partners and hard drug use were not associated with HIVST usage among MSM. CONCLUSIONS: HIVST usage among migrants from the UK, France and the Netherlands was relatively low between 2014 and 2015 but higher among migrant MSM. To increase HIV testing rates among migrants, programmes need to be developed to promote HIVST among this group. Also, as more countries approve usage of HIVST, systems need to be established to ensure linkage to confirmatory testing and care following a positive test

Acceptability of HIV self-sampling kits (TINY vial) among people of black African ethnicity in the UK: a qualitative study

Background: Increasing routine HIV testing among key populations is a public health imperative, so improving access to acceptable testing options for those in need is a priority. Despite increasing targeted distribution and uptake of HIV self-sampling kits (SSKs) among men who have sex with men in the UK, little is known about why targeted SSK interventions for black African users are not as wide-spread or well-used. This paper addresses this key gap, offering insight into why some groups may be less likely than others to adopt certain types of SSK interventions in particular contexts. These data were collected during the development phase of a larger study to explore the feasibility and acceptability of targeted distribution of SSKs to black African people. Methods: We undertook 6 focus groups with members of the public who self-identified as black African (n = 48), 6 groups with specialists providing HIV and social services to black African people (n = 53), and interviews with HIV specialist consultants and policy-makers (n = 9). Framework analysis was undertaken, using inductive and deductive analysis to develop and check themes. Results: We found three valuable components of targeted SSK interventions for this population: the use of settings and technologies that increase choice and autonomy; targeted offers of HIV testing that preserve privacy and do not exacerbate HIV stigma; and ensuring that the specific kit being used (in this case, the TINY vial) is perceived as simple and reliable. Conclusions: This unique and rigorous research offers insights into participants’ views on SSK interventions, offering key considerations when targeting this population.. Given the plethora of HIV testing options, our work demonstrates that those commissioning and delivering SSK interventions will need to clarify (for users and providers) how each kit type and intervention design adds value. Most significantly, these findings demonstrate that without a strong locus of control over their own circumstances and personal information, black African people are less likely to feel that they can pursue an HIV test that is safe and secure. Thus, where profound social inequalities persist, so will inequalities in HIV testing uptake – by any means

Migrant Health: Sexual transmission of HIV within migrant groups in the EU/EEA and implications for effective interventions

This report presents the published evidence of sexual transmission of HIV among populations from countries with generalised HIV epidemics in the European Union/European Economic Area (EU/EEA). Member states’ surveillance systems for monitoring the sexual transmission of HIV in the EU/EEA among migrant populations are also profiled. The implications of this evidence are summarised and recommendations provided for those Member States that wish to improve their surveillance systems in order to assess the sexual transmission of HIV in their at-risk migrant populations. The evidence can also be used as a basis for policy and programmatic activities targeted toward migrant populations

Cost-per-diagnosis as a metric for monitoring cost effectiveness of HIV testing programmes in low income settings in southern Africa : health economic and modelling analysis

Introduction: As prevalence of undiagnosed HIV declines, it is unclear whether testing programmes will be cost effective. To guide their HIV testing programmes,countries require appropriatemetrics that can be measured. The cost-per-diagnosisis potentially a useful metric. Methods:We simulated a series of setting-scenarios for adult HIV epidemics and ART programmes typical of settings in southern Africa using an individual-based model and projected forward from 2018 under two policies: (i) a minimum package of “core” testing (i.e. testing in pregnant women, for diagnosis of symptoms, in sex workers, and in men coming forward for circumcision) is conducted, and (ii) “core” testing as above plus “additional-testing”, for which we specify different rates of testing and various degrees to which those with HIV are more likely to test than thosewithout HIV. We also considered a plausible range of unit test costs. The aim was to assess the relationship between cost-per-diagnosisand the incremental cost-effectiveness ratio(ICER) of the additional-testingpolicy. Discount rate 3%; costs in 2018 $US. Results:There was a strong graded relationship between the cost-per-diagnosisand the ICER. Overall, the ICERwas below$500 per-DALY-averted (the cost effectiveness threshold used in primary analysis) so long as thecost-per-diagnosiswas below $315. This thresholdcost-per-diagnosiswas similar according to epidemic and programmatic features including the prevalence of undiagnosed HIV, the HIV incidence and a measure of HIV programme quality (the proportion of HIV diagnosed people having a viral load <1000 copies/mL). However, restrictingto women, additional-testingdid not appear cost-effective even at acost-per-diagnosisof below$50, while restrictingto men additional-testingwas cost effective up to a cost-per-diagnosisof $585. Thethreshold cost for testing in men fell to$256 when the cost effectiveness threshold was $300instead of$500, and to $81 when considering a discount rate of 10% perannum.Conclusions:For testing programmesin low income settings in southern African there is an extremely strong relationship between the cost-per-diagnosisand the cost per DALY averted, indicating that the cost-per-diagnosiscan be used to monitor the cost effectiveness of testing programmes

HIV testing history and access to treatment among migrants living with HIV in Europe.

Migrants are overrepresented in the European HIV epidemic. We aimed to understand the barriers and facilitators to HIV testing and current treatment and healthcare needs of migrants living with HIV in Europe. A cross-sectional study was conducted in 57 HIV clinics in nine countries (Belgium, Germany, Greece, Italy, The Netherlands, Portugal, Spain, Switzerland and United Kingdom), July 2013 to July 2015. HIV-positive patients were eligible for inclusion if they were as follows: 18 years or older; foreign-born residents and diagnosed within five years of recruitment. Questionnaires were completed electronically in one of 15 languages and linked to clinical records. Primary outcomes were access to primary care and previous negative HIV test. Data were analysed using random effects logistic regression. Outcomes of interest are presented for women, heterosexual men and gay/bisexual men. A total of 2093 respondents (658 women, 446 heterosexual men and 989 gay/bisexual men) were included. The prevalence of a previous negative HIV test was 46.7%, 43.4% and 82.0% for women, heterosexual and gay/bisexual men respectively. In multivariable analysis previous testing was positively associated with: receipt of post-migration antenatal care among women, permanent residency among heterosexual men and identifying as gay rather than bisexual among gay/bisexual men. Access to primary care was found to be high (&gt;83%) in all groups and was strongly associated with country of residence. Late diagnosis was common for women and heterosexual men (60.8% and 67.1%, respectively) despite utilization of health services prior to diagnosis. Across all groups almost three-quarters of people on antiretrovirals had an HIV viral load &lt;50 copies/mL. Migrants access healthcare in Europe and while many migrants had previously tested for HIV, that they went on to test positive at a later date suggests that opportunities for HIV prevention are being missed. Expansion of testing beyond sexual health and antenatal settings is still required and testing opportunities should be linked with combination prevention measures such as access to PrEP and treatment as prevention
