    Abstract. The phenotypic relationship between live body weight (kg) and body measurements (cm) for Sudanese bulls is explored. In this research, data from one visit survey were used to estimate the relationships between live body weight and some body measurements of Sudanese Kenana bulls. General linear model analysis with multivariate ANOVA when all physical variables were response and animal live body weight groups (kg) as independent, and simple linear Pearson's correlation were formed between live body weight (Bwt), Heart girth (HG), Heart girth at hump (HTH), Body length (Bl) and Abdominal girth (ABG). The results revealed the best linear correlation between body weight and measurements was heart girth at hump (0.65, 0.66 and 0.73) respectively, for live body weight groups. The obtained linear correlation coefficients were relatively highly accurate indicators of live body weight. This suggests that live body weight could be estimated accurately by body measurements in Sudanese Kenana Bulls. Keywords: live body weight, body measurements, correlation, Kenana bulls, Sudan Abstrak.

    Abstract Background The Ministry of Health (hereafter, Ministry) of Trinidad and Tobago is responsible for delivery of all health services in the country. The Ministry takes responsibility for direct delivery of care in the public sector and has initiated a process whereby those seeking HIV test results could obtain confidential reports during a single-visit to a testing location. The Ministry requested technical assistance with this process from the Caribbean Epidemiology Centre (CAREC). The United States Centers for Disease Control and Prevention (CDC) played an important role in this process through its partnership with CAREC. Methods Under the technical guidance of CAREC and CDC, the Ministry organized a technical working group which included representatives from key national HIV program services and technical assistance partners. This working group reviewed internationally-recognized best practices for HIV rapid testing and proposed a program that could be integrated into the national HIV programs of Trinidad and Tobago. The working group wrote a consensus protocol, defined certification criteria, prepared training materials and oversaw implementation of "same-visit" HIV testing at two pilot sites. Results A Ministry-of-Health-supported program of "same-visit" HIV testing has been established in Trinidad and Tobago. This program provides confidential testing that is independent of laboratory confirmation. The program allows clients who want to know their HIV status to obtain this information during a single-visit to a testing location. Testers who are certified to provide testing on behalf of the Ministry are also counselors. Non-laboratory personnel have been trained to provide HIV testing in non-laboratory locations. The program includes procedures to assure uniform quality of testing across multiple testing sites. Several procedural and training documents were developed during implementation of this program. This report contains links to those documents. Conclusions The Ministry of Health has implemented a program of "same-visit" HIV testing in Trinidad and Tobago. This program provides clients confidential HIV test reports during a single visit to a testing location. The program is staffed by non-laboratory personnel who are trained to provide both testing and counseling in decentralized (non-laboratory) settings. This approach may serve as a model for other small countries.</p

    Objective: To estimate the impact and cost-effectiveness of treatment as prevention (TasP), pre-exposure prophylaxis (PrEP) and condom promotion for serodiscordant couples in Nigeria. / Design: Mathematical and cost modelling. / Methods: A deterministic model of HIV-1 transmission within a cohort of serodiscordant couples and to/from external partners was parameterized using data from Nigeria and other African settings. The impact and cost-effectiveness were estimated for condom promotion, PrEP and/or TasP, compared with a baseline where antiretroviral therapy (ART) was offered according to 2010 national guidelines (CD4+ <350 cells/μl) to all HIV-positive partners. The impact was additionally compared with a baseline of current ART coverage (35% of those with CD4+ <350 cells/μl). Full costs (in US 2012)ofprogrammeintroductionandimplementationwereestimatedfromaproviderperspective./Results:SubstantialbenefitscamefromscalingupARTtoallHIVpositivepartnersaccordingto2010nationalguidelines,withadditionalsmallerbenefitsofprovidingTasP,PrEPorcondompromotion.ComparedwithabaselineofofferingARTtoallHIVpositivepartnersatthe2010nationalguidelines,condompromotionwasthemostcosteffectivestrategy[US2012) of programme introduction and implementation were estimated from a provider perspective. / Results: Substantial benefits came from scaling up ART to all HIV-positive partners according to 2010 national guidelines, with additional smaller benefits of providing TasP, PrEP or condom promotion. Compared with a baseline of offering ART to all HIV-positive partners at the 2010 national guidelines, condom promotion was the most cost-effective strategy [US 1206/disability-adjusted-life-year (DALY)], the next most cost-effective intervention was to additionally give TasP to HIV-positive partners (incremental cost-effectiveness ratio US 1607/DALY),followedbyadditionallygivingPrEPtoHIVnegativepartnersuntiltheirHIVpositivepartnersinitiateART(US1607/DALY), followed by additionally giving PrEP to HIV-negative partners until their HIV-positive partners initiate ART (US 7870/DALY). When impact was measured in terms of infections averted, PrEP with condom promotion prevented double the number of infections as condom promotion alone. / Conclusions: The first priority intervention for serodiscordant couples in Nigeria should be scaled up ART access for HIV-positive partners. Subsequent incremental benefits are greatest with condom promotion and TasP, followed by PrEP

    Post-Kala-azar Dermal Leishmaniasis in Nepal: A Retrospective Cohort Study (2000–2010)

    Get PDF
    Post-kala-azar dermal leishmaniasis (PKDL) is a skin disorder seen in patients treated for Leishmania donovani visceral leishmaniasis (VL), a neglected tropical disease that is fatal if left untreated. In the Indian subcontinent, PKDL is seen in 5–10% of all past VL cases and is also reported in some without history of VL. As persons with PKDL do not feel sick, the disease has only cosmetic significance for the individual and treatment is rarely sought. However, PKDL lesions harbour parasites and therefore could represent a source of transmission, through the bite of female sand flies. Our study shows that the occurrence of PKDL in patients with past treated VL is low in Nepal compared to neighboring countries. Treatment of the original VL episode with SSG (sodium stibogluconate), inadequate treatment and treatment on ambulatory basis were significantly associated with PKDL. Though SSG has since been replaced by other drugs, counseling and supervision of adherence to the prescribed VL treatment is of vital importance to reduce risk of treatment failure and relapse as well as later development of PKDL. Policy makers should include surveillance and case management of PKDL in the VL elimination program

    A comprehensive situation assessment of injection practices in primary health care hospitals in Bangladesh

    <p>Abstract</p> <p>Background</p> <p>Understanding injection practices is crucial for evidence-based development of intervention initiatives. This study explored the extent of injection use and injection safety practices in primary care hospitals in Bangladesh.</p> <p>Methods</p> <p>The study employed both quantitative and qualitative research methods. The methods used were - a retrospective audit of prescriptions (n = 4320), focus group discussions (six with 43 participants), in-depth interviews (n = 38) with a range service providers, and systematic observation of the activities of injection providers (n = 120), waste handlers (n = 48) and hospital facilities (n = 24). Quantitative and qualitative data were assessed with statistical and thematic analysis, respectively, and then combined.</p> <p>Results</p> <p>As many as 78% of our study sample (n = 4230) received an injection. The most commonly prescribed injections (n = 3354) including antibiotics (78.3%), IV fluids (38.6%), analgesics/pain killers (29.4%), vitamins (26.7%), and anti-histamines (18.5%). Further, 43.7% (n = 1145) of the prescribed antibiotics (n = 2626) were given to treat diarrhea and 42.3% (n = 600) of IV fluids (n = 1295) were used to manage general weakness conditions. Nearly one-third (29.8%; n = 36/120) of injection providers reported needle-stick injuries in the last 6 months with highest incidences in Rajshahi division followed by Dhaka division. Disposal of injection needles, syringes and other materials was not done properly in 83.5% (n = 20/24) of the facilities. Health providers' safety concerns were not addressed properly; only 23% (n = 28/120) of the health providers and 4.2% (n = 2/48) of the waste handlers were fully immunized against Hepatitis B virus. Moreover, 73% (n = 87/120) of the injection providers and 90% (n = 43/48) of the waste handlers were not trained in injection safety practices and infection prevention. Qualitative data further confirmed that both providers and patients preferred injections, believing that they provide quick relief. The doctors' perceived injection use as their prescribing norm that enabled them to prove their professional credibility and to remain popular in a competitive health care market. Additionally, persistent pressure from hospital administration to use up injections before their expiry dates also influenced doctors to prescribe injections regardless of actual indications.</p> <p>Conclusions</p> <p>As far as the patients and providers' safety is concerned, this study demonstrated a need for further research exploring the dynamics of injection use and safety in Bangladesh. In a context where a high level of injection use and unsafe practices were reported, immediate prevention initiatives need to be operated through continued intervention efforts and health providers' training in primary care hospitals in Bangladesh.</p

    Using European travellers as an early alert to detect emerging pathogens in countries with limited laboratory resources

    BACKGROUND: The volume, extent and speed of travel have dramatically increased in the past decades, providing the potential for an infectious disease to spread through the transportation network. By collecting information on the suspected place of infection, existing surveillance systems in industrialized countries may provide timely information for areas of the world without adequate surveillance currently in place. We present the results of a case study using reported cases of Shigella dysenteriae serotype 1 (Sd1) in European travellers to detect "events" of Sd1, related to either epidemic cases or endemic cases in developing countries. METHODS: We identified papers from a Medline search for reported events of Sd1 from 1940 to 2002. We requested data on shigella infections reported to the responsible surveillance entities in 17 European countries. Reports of Sd1 from the published literature were then compared with Sd1 notified cases among European travellers from 1990 to 2002. RESULTS: Prior to a large epidemic in 1999–2000, no cases of Sd1 had been identified in West Africa. However, if travellers had been used as an early warning, Sd1 could have been identified in this region as earlier as 1992. CONCLUSION: This project demonstrates that tracking diseases in European travellers could be used to detect emerging disease in developing countries. This approach should be further tested with a view to the continuous improvement of national health surveillance systems and existing European networks, and may play a significant role in aiding the international public health community to improve infectious disease control
