EFFECT OF VIDEO-TAPED INSTRUCTION ON ACHIEVEMENT AND GENDER AMONG JUNIOR SECONDARY SCHOOL STUDENTS IN FEDERAL CAPITAL TERRITORY, ABUJA, NIGERIA

The deplorable state of mathematics in the country has been a source of concern to Mathematics educators, Government and the Society at large. The effect of an innovative method such the use of videotaped instruction for learning mathematics at junior secondary school level was therefore experimented. A random sampling technique was used in selecting the three schools out of 50 junior secondary schools in Federal Capital Territory (FCT), Abuja, Nigeria, with each serving as experimental group consisting of 81 males and 83 females (164) and control group, consisting of 80 male and 78 female (158), which gave a total sample size of 322 students. This study adopted a quasi-experimental research design with non-equivalent pretest, posttest control group design. A validated 40 multiple-choice items of Mathematics Achievement Test (MAT) developed by the researcher, was used in accessing the outcome of the study. Two research questions and two hypotheses guided the study. Mean and Standard deviation was used for answering the research questions while Analysis of Covariance (ANCOVA) was used for testing the hypotheses at 0.05 levels of significance. The result revealed that there was no significant gender difference between male and female taught Mathematics using video-taped instruction (FCal 1,322 =100, p>.05). And there is no significant interaction effect between teaching method and gender on students’ achievement in mathematics (FCAL 1,322 = 1.99; P>.05). That means that there is a significant treatment difference (FCal 1,322=160.98, p<.05). The researcher recommended that workshops, seminars and conferences should be organized for teachers on the importance of video-taped instructions for the teaching and learning of Mathematics.  Article visualizations

Effectiveness of blood utilization across departments in a tertiary health institution

Intruduction: The limited availability of blood makes it imperative that Hospitals and transfusion centres employ blood utilization indicators to ensure effective and efficient use. This study is a review of the transfusion practices and blood utilization Indicators of the largest tertiary health centre in South East Nigeria. Material and methods: The study is a retrospective cross-sectional Hospital based type. The following, biodemographic data, clinical diagnosis, and blood bank information such as patient and donor blood types from a 3-year period (January 2018–January 2021) was reviewed. The total number of units crossmatched, issued, transfused, or returned was extracted. Utilization Indicators such as crossmatch to transfusion ratio, transfusion probability, and transfusion index were calculated and our findings were compared to similar studies performed in centres located in India, Ethiopia and Saudi Arabia Results: A total of 2,919 blood units were cross-matched out of which 2,212 units were transfused to 1,953 patients. The study reported an overall crossmatch to transfusion rate of 1.3, a Transfusion probability of 71%, and a transfusion index of 1.1. These findings compare favourably with findings reported from studies done in other LMIC countries. Comparatively, the Department of Medicine with a crossmatch to transfusion ratio of 1.1 has the most efficient blood ordering practices. Conclusion: The study findings showed that the quality indicators on the utilization of blood are in keeping with international best practices. Implementation of policies like the Maximum surgical blood ordering schedule (MSBOS) could further strengthen the practice and improve the results of the surgical disciplines

Is renal medullary carcinoma the seventh nephropathy in sickle cell disease? A multi-center Nigerian survey

Introduction: Previous studies had enlisted renal medullary carcinoma (RMC) as the seventh nephropathy in sickle cell disease (SCD). Clinical experience has contradicted this claim and this study is targeted at refuting or supporting this assumption.Objective: To estimate the prevalence of RMC and describe other renal complications in SCD.Materials and methods: 14 physicians (haematologists and urologists) in 11 tertiary institutions across the country were collated from patients’ case notes and hospital SCD registers.Results: Of the 3,596 registered sickle patients, 2 (0.056%) had been diagnosed with RMC over a ten year period, thereby giving an estimated prevalence rate of 5.6 per 100,000. The most common renal complication reported by the attending physicians was chronic kidney disease (CKD). The frequency of routine renal screening for SCD patients varied widely between centres – most were done at diagnosis, annually or bi-annually.Conclusion: The ten year prevalence of RMC in Nigerian SCD patients was determined to be 5.6 (estimated incidence of 0.56). RMC is not more common in SCD patients and therefore cannot be regarded as a “Seventh Sickle nephropathy”. Most of the managing physicians reported that the commonest nephropathy observed in their SCD patients was chronic kidney disease.Keywords: Renal medullary carcinoma, seventh nephropathy, sickle cell disease, Nigerian surve
