Managing a Sustainable Institutional Repository: The Covenant University Experience

The paper examined the ubiquitous nature of digital institutional repositories and their concomitant capabilities. It specifically show-cased the robust process and technical details involved in the development and sustenance of Covenant University Institutional Repository which has consistently ranked number one repository in Nigeria based on webometric rankings. Relying on Strajda Process Management model, Covenant University adopted two open source software- Dspace and E-print based on adjudged robustness of the metadata, relative easy to setup as well as amenable to customization. The paper recommended among others, the sensitization of researchers on the dangers of ceding copyright to Journal publishers as the practice divests them of inherent rights and may preclude deposition of their works on the Institutional repository thereby undermining growth of content and visibility of research outputs. It further recommended backup systems that forestall intrusion and mitigate effect of potential disasters on sustainability of Institutional Repository

Turner syndrome and associated problems in turkish children: A multicenter study

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population. Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014. Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosi) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto’s thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%. Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespan. © Journal of Clinical Research in Pediatric Endocrinology

Promising outcomes of a national programme for the prevention of mother-to-child HIV transmission in Addis Ababa: a retrospective study

<p>Abstract</p> <p>Background</p> <p>Prevention of Mother-to-Child HIV Transmission (PMTCT) is still the most effective intervention in combating new HIV infections. In 2008, revised national PMTCT guidelines that incorporated new policies on HIV counselling and testing, antiretroviral prophylaxis regimen and infant HIV diagnosis came into effect in Ethiopia. In the present study we have examined trends in PMTCT service utilization and assessed the rate of MTCT in relation to policy changes in the national PMTCT programme.</p> <p>Methods</p> <p>Reports from February 2004 to August 2009 were reviewed in 10 sub-cities in Addis Ababa, Ethiopia. The data was collected from May to October 2009.</p> <p>Results</p> <p>The proportion of women who received HIV counselling and testing among new antenatal care attendees increased from 50.7% (95% CI 50.2-51.2) in 2007 to 84.5% (95% CI 84.1-84.9) in 2009 following the shift to routine opt-out testing. Nevertheless, in 2009 only 53.7% of the positive women and 40.7% of their infants received antiretroviral prophylaxis. The HIV prevalence among antenatal attendees decreased significantly from 10.5% in 2004 to 4.6% in 2009 in parallel to the increased number of women being tested. The HIV positive women were over 18 times (RR 18.5, p < 0.0001) more likely to be referred for treatment, care and support in 2009 than in 2004. The proportion of partners tested for HIV decreased by 14% in 2009 compared to 2004, although the absolute number was increasing year by year. Only 10.6% (95% CI 9.9-11.2) of the HIV positive women completed their follow up to infant HIV testing. The cumulative probability of HIV infection among babies on single dose nevirapine regimen who were tested at >=18 months was 15.0% (95% CI 9.8-22.1) in 2007, whereas it was 8.2% (95% CI 5.55-11.97) among babies on Zidovudine regimen who were tested at >=45 days in 2009.</p> <p>Conclusion</p> <p>The paper demonstrates trends in PMTCT service utilization in relation to changing policy. There is marked improvement in HIV counselling and testing service utilization, especially after the policy shift to routine opt-out testing. However, despite policy changes, the ARV prophylaxis uptake, the loss to follow up and the partner testing have remained unchanged across the years. This should be a matter of immediate concern and a topic for further research.</p

Assessing the efficiency of mother-to-child HIV prevention in low- and middle-income countries using data envelopment analysis

AIDS is one of the most significant health care problems worldwide. Due to the difficulty and costs involved in treating HIV, preventing infection is of paramount importance in controlling the AIDS epidemic. The main purpose of this paper is to explore the potential of using Data Envelopment Analysis (DEA) to establish international comparisons on the efficiency of implementation of HIV prevention programmes. To do this we use data from 52 low- and middle-income countries regarding the prevention of mother-to-child transmission of HIV. Our results indicate that there is a remarkable variation in the efficiency of prevention services across nations, suggesting that a better use of resources could lead to more and improved services, and ultimately, prevent the infection of thousands of children. These results also demonstrate the potential strategic role of DEA for the efficient and effective planning of scarce resources to fight the epidemic

The Uptake of Integrated Perinatal Prevention of Mother-to-Child HIV Transmission Programs in Low- and Middle-Income Countries: A Systematic Review

BACKGROUND: The objective of this review was to assess the uptake of WHO recommended integrated perinatal prevention of mother-to-child transmission (PMTCT) of HIV interventions in low- and middle-income countries. METHODS AND FINDINGS: We searched 21 databases for observational studies presenting uptake of integrated PMTCT programs in low- and middle-income countries. Forty-one studies on programs implemented between 1997 and 2006, met inclusion criteria. The proportion of women attending antenatal care who were counseled and who were tested was high; 96% (range 30-100%) and 81% (range 26-100%), respectively. However, the overall median proportion of HIV positive women provided with antiretroviral prophylaxis in antenatal care and attending labor ward was 55% (range 22-99%) and 60% (range 19-100%), respectively. The proportion of women with unknown HIV status, tested for HIV at labor ward was 70%. Overall, 79% (range 44-100%) of infants were tested for HIV and 11% (range 3-18%) of them were HIV positive. We designed two PMTCT cascades using studies with outcomes for all perinatal PMTCT interventions which showed that an estimated 22% of all HIV positive women attending antenatal care and 11% of all HIV positive women delivering at labor ward were not notified about their HIV status and did not participate in PMTCT program. Only 17% of HIV positive antenatal care attendees and their infants are known to have taken antiretroviral prophylaxis. CONCLUSION: The existing evidence provides information only about the initial PMTCT programs which were based on the old WHO PMTCT guidelines. The uptake of counseling and HIV testing among pregnant women attending antenatal care was high, but their retention in PMTCT programs was low. The majority of women in the included studies did not receive ARV prophylaxis in antenatal care; nor did they attend labor ward. More studies evaluating the uptake in current PMTCT programs are urgently needed

Early infant HIV-1 diagnosis programs in resource-limited settings: opportunities for improved outcomes and more cost-effective interventions

Early infant diagnosis (EID) of HIV-1 infection confers substantial benefits to HIV-infected and HIV-uninfected infants, to their families, and to programs providing prevention of mother-to-child transmission (PMTCT) services, but has been challenging to implement in resource-limited settings. In order to correctly inform parents/caregivers of infant infection status and link HIV-infected infants to care and treatment, a 'cascade' of events must successfully occur. A frequently cited barrier to expansion of EID programs is the cost of the required laboratory assays. However, substantial implementation barriers, as well as personnel and infrastructure requirements, exist at each step in the cascade. In this update, we review challenges to uptake at each step in the EID cascade, highlighting that even with the highest reported levels of uptake, nearly half of HIV-infected infants may not complete the cascade successfully. We next synthesize the available literature about the costs and cost effectiveness of EID programs; identify areas for future research; and place these findings within the context of the benefits and challenges to EID implementation in resource-limited settings

Dominancy of Insect Families and Species Recorded in Almond Orchards of Turkey

This study which is entitled the insect fauna of Southeastern and Eastern Anatolia Regions was carried out during 2002-2004. Samples were taken from the orchards in Diyarbakir, Elazig and Mardin provinces by employing methods such as striking, burlap band traps, and visual examinations of leaves, twigs and other parts of the trees. Trees selected for sampling were inspected once week between March and November. Generally eudominant were the order Coleoptera and Heteroptera. Dominant were only the imagoes order Homoptera and subdominant were Hymenoptera and Lepidoptera. The rest 6 orders were subrecedent. As result of this study 205 species spread areas and abundance belonging to 56 families in 11 orders were determined. 205 insects species which were determined in three administrative provinces and on only a culture plant are very important for insects potential in almond areas with this study. This study is very important to be a base to integred pest management studies which will be made in the future

До питання знахідок Heteroptera (Insecta: Hemiptera) з Ірану

In this faunistic paper, the fauna of Heteroptera was studied in some regions of Iran. Totally, 18 species within eight families were collected and identified: Berytidae (two species, two genera), Coreidae (two species, two genera), Hebridae (one species), Miridae (three species, three genera), Piesmatidae (one species), Reduviidae (four species, three genera), Rhyparochromidae (two species, two genera), and Tingidae (three species, three genera). Three species, Galeatus affinis (Herrich-Schaeffer, 1835) (Tingidae), Hebrus (Hebrus) liliimacula Horváth, 1929 (Hebridae) and Parapiesma salsolae (Becker, 1867) (Piesmatidae) are new records for the fauna of Iran.У роботі представлені результати вивчення фауни Heteroptera в різних провінціях Ірану протягом 2010-2016 років.

Digitization and admissibility of digital records in Nigerian courts: strategies and lessons for the LIS profession

The global impetus and preference for automation of records management systems arising from propensity for greater efficiency and preservation imperatives has sustained the digitization of records from creation, retention, archival to disposal. The paper examined the admissibility of digital records as evidence in Nigerian courts. It noted that the Nigerian Evidence Act has not been reviewed for over sixty years hence it 1s large/} deficient m accommodating technological developments compared to its counterparts m advanced nat10ns. The requisite laws place highest premium on primary evidence as exemplified by original documents and regard digital records as surrogate and secondary evidence hence not admissible The courts can only be persuaded to recognize third party authenticated versions. It is recommended inter alia that records of legal value should be notarized before digitization. regard digital records as surrogate and secondary evidence hence not admissible The courts can only be persuaded to recognize third party authenticated versions.
