How well Nigerian radiographers adhere to pediatrics-specific protocols during computed tomography procedures

INTRODUCTION: Enormously high-dose procedures such as computed tomography requires pediatrics-specific protocols due to high tissue radio-sensitivity and higher lifetime attributable cancer risks. It’s not known if radiographers in Nigeria consider this fact at all times.This work aimed to survey head computed tomography dose in Nigeria for evidence of pediatric- specific practice. METHODS: The census of CT scanners was undertaken prospectively across the country from June 2019 to September 2021, while the dose survey was undertaken retrospectively in 14 facilities distributed evenly across the geopolitical zones between February to September 2021. Data on computed tomography installations were supplied by radiographers spread across the country. A dose survey involving 490 and 700 pediatrics and adult patients emanated from fourteen of those facilities. Doses were extracted from on-screen volumetric CT dose index (CTDIvol) and dose- length product (DLP) in non-contrast investigations. RESULTS: There were 209 CT scanners installed in Nigeria as of September 2021, with a triennial growth rate of 12.4% (n = 26). Monthly patient throughput for all CT requests was ≤ 41,412 with pediatric cases accounting for 10.4 % (n = 4,311). Mean head dose for pediatrics and adults with CTDIvol (41/58 mGy) and DLP (922/1198 mGy-cm) appeared different prima facie. However, a paired - sample t-test gave statistically significant difference in the CTDIvol (p = 0.001), but not with DLP (p = 0.055). CONCLUSION: The installation of CT scanners is on the increase in Nigeria. Pediatric and adult CT dose had minimal differences. Given the higher lifetime attributable cancer risks for pediatrics, this should be worrisome. This calls for pediatric- specific protocol design and enforcement by relevant regulatory agencies, as well as meticulous optimization of protection from radiation by radiation practitioners

Comparative study on composition of insect in close and open nursery of Federal College of Forestry Jos, Plateau State, Nigeria

Nursery being an area where young plants are raised before sowing or transplanting in gardens or field contains rich insect assemblages whose composition and abundance is under researched even in research institutes. Thus, the comparative study on the composition of insect in close and open nursery of Federal College of Forestry Jos, Plateau State, Nigeria was carried out in May 2015 in relation to the abundance and diversity of insect using pitfall trap and hand-picking sampling techniques. A total of 2,052 individuals distributed into 13 orders, 39 families, 50 genera and 55 species were collected. 1,557 (75.9%) individuals were collected from the open nursery (with: 13 orders, 39 families, 41 genera and 46 species) while, 495 (24.1%) individuals were found in the close nursery (with: 11 orders, 27 families, 38 genera and 47 species). Five individuals could not be identified beyond class and order levels. The distribution of insect taxa in descending order showed that Hymenoptera (62.8%), Coleoptera (11.1%) and Orthoptera (10.1%) are the most dominant, with Hymenoptera occurring the most in both sites. There was no significant difference (P > 0.05) in the pooled abundance of insect from both sampling techniques between the two nursery types. Although, insect abundance from pitfall trap collection between the two nursery types showed a significant difference (t= -2.494, df = 8, P = 0.03729) while, no significant difference (t= 1.0263, df = 8, P= 0.3348) for hand-picked insect between the two nursery types. To this end, this study shows that the nursery of Federal College of Forestry Jos is healthy due to the abundant and diverse insect species recorded in which the phytophagus individuals are the most dominant group, but are kept under check by the predaceous ones. The pitfall trap was a more efficient collection technique and should be used by insect collectors.Keywords: Close and open nursery, insect, pitfall trap, hand-pickin

Composition and Distribution of Mosquito Vectors in a Peri-Urban Community Surrounding an Institution of Learning in Lafia Metropolis, Nasarawa State, Central Nigeria

Vector surveillance is very key in solving mosquito-borne health problems in Nigeria. To this end, the composition and distribution of mosquito vectors in a peri-urban community surrounding an institution of learning in Lafia metropolis, Nasarawa State, Central Nigeria was carried out between December 2016 and June 2017. The Prokopack Aspirator was used to collect indoor resting mosquitoes between 6:00 a.m. and 9:00 a.m. from 30 randomly selected houses. Mosquitoes collected were knocked down and transferred into a well labelled petri-dish and taken to the laboratory for processing. A total of 664 mosquitoes were collected which spread across Culex quinquefasciatus 572 (86.14%), Anopheles gambiae 88 (13.25%) and Aedes aegypti 4 (0.60%). The abundance of mosquitoes in relation to seasons, species, sex, abdominal conditions as well as transmission indices across seasons significantly varied (P 0.05). The inhabitants of the area should ensure that all drainages flow through so as to reduce mosquito breeding grounds. Also, members of the community should always protect themselves by sleeping under insecticide treated bed nets

Anti-trypanosomal Activity of Bufonidae (Toad) Venom Crude Extract on Trypanosoma brucei brucei in Swiss Mice

Trypanosomiasis afflicts about 6 ~ 7 million people globally and to a large extent impedes livestock production in Africa. Naturally, trypanosomal parasites undergo genetic mutation and have developed resistance over a wide range of therapies. The utilization of animals and plants products has presented therapeutic potential for identifying novel anti-trypanosomal drugs. This study evaluated toad venom for anti-trypanosomal potency invivo in Swiss mice. Toads were collected from July to August 2019. The acute oral toxicity and biochemical characterization of the toad venom were determined. The experimental mice were administered various doses (130 mg/kg, 173 mg/kg and 217 mg/kg) of the toad venom crude extract and 0.75 mg/mL of Diamizan Plus standard drug for the treatment of trypanosomiasis, once daily for 3 days. The in-vivo anti-trypanosomal activity was evaluated by a curative test, after infecting the mice with Trypanosoma brucei brucei. The pre-patent period was 72 hours before treatment commenced. The overall results showed that trypanosomal load was highest in the control group while the group treated with Diamizan drug had the least trypanosomal load. As such, the mean trypanosomal load in relation to treatments showed a very high significant difference (P0.05) across treatment groups. The over 50% reduction in the trypanosomal load in the 130 mg/kg group in comparison with the control group brings to bare the anti-trypanosomal potency of the toad venom. The anti-trypanosomal activity demonstrated by the toad venom has provided basis for development of new therapeutic agents from different toad species. The study recommends further studies (both in-vivo and invitro) followed by the characterization of the active compounds present in the toad venom responsible for the anti-tyrpanosomal activity observed alongside the management and conservation of these species

Stakeholder perspectives and requirements to guide the development of digital technology for palliative cancer services: a multi-country, cross-sectional, qualitative study in Nigeria, Uganda and Zimbabwe

Introduction: Coverage of palliative care in low and middle-income countries is very limited, and global projections suggest large increases in need. Novel approaches are needed to achieve the palliative care goals of Universal Health Coverage. This study aimed to identify stakeholders’ data and information needs and the role of digital technologies to improve access to and delivery of palliative care for people with advanced cancer in Nigeria, Uganda and Zimbabwe. Methods: We conducted a multi-country cross-sectional qualitative study in sub-Saharan Africa. In-depth qualitative stakeholder interviews were conducted with N = 195 participants across Nigeria, Uganda and Zimbabwe (advanced cancer patients n = 62, informal caregivers n = 48, health care professionals n = 59, policymakers n = 26). Verbatim transcripts were subjected to deductive and inductive framework analysis to identify stakeholders needs and their preferences for digital technology in supporting the capture, transfer and use of patient-level data to improve delivery of palliative care. Results: Our coding framework identified four main themes: i) acceptability of digital technology; ii) current context of technology use; iii) current vision for digital technology to support health and palliative care, and; iv) digital technologies for the generation, reporting and receipt of data. Digital heath is an acceptable approach, stakeholders support the use of secure data systems, and patients welcome improved communication with providers. There are varying preferences for how and when digital technologies should be utilised as part of palliative cancer care provision, including for increasing timely patient access to trained palliative care providers and the triaging of contact from patients. Conclusion: We identified design and practical challenges to optimise potential for success in developing digital health approaches to improve access to and enhance the delivery of palliative cancer care in Nigeria, Uganda and Zimbabwe. Synthesis of findings identified 15 requirements to guide the development of digital health approaches that can support the attainment of global health palliative care policy goals

Determinants of utilization of maternity services in Gidan Igwe, Sokoto, Nigeria

Background: The provision of antenatal care is regarded as the cornerstone of maternal and perinatal health care especially in developing nations and is expected to have a significant impact on achieving the fifth millennium development goal. The aim of this study was to assess the determinants of utilisation of maternity services in Gidan Igwe, Sokoto. Methods: The study was a cross-sectional descriptive one involving 300 women of child bearing age selected through a systematic sampling technique. Data was collected using a set of semi-structured interviewer and self administered questionnaires. Results: Majority, 214 (71.3%) of the respondents had no formal education, visited a health facility for antenatal care during their last pregnancy, 218 (72.7%) and had their last delivery at home, 190 (63.3%). Of the 190 subjects that delivered at home, 165 (85%) were assisted by Traditional birth attendants (TBAs). Education was statistically significantly associated with ANC attendance and hospital delivery (P=0.0012). Conclusion: Although, a high proportion of the respondents visited health facilities for ANC, only a few of them delivered in these facilities. There is need to increase public awareness on the use of antenatal care services and delivery by skilled attendants
