EXPLORING THE BENEFITS OF ACTIVITY-BASED LEARNING IN ENHANCING COGNITIVE SKILLS OF SECONDARY SCHOOL SCIENCE AND TECHNOLOGY STUDENTS IN SOUTH-SOUTH, NIGERIA

Improving the quality of Science and Technology education requires effective teaching techniques, which largely depend on the development of teachers' pedagogical skills. This study examines how the application of the Activity-Based Learning (ABL) approach influences Secondary School Science and Technology students' cognitive learning abilities. These skills are examined based on Bloom's Taxonomy, and are evaluated by their teachers. The study also investigated the teachers' ability to effectively apply the ABL approach after receiving training. The study formulated two research questions and a hypothesis; and focused on Basic Science and Technology (BST) students in three districts of the State of Akwa Ibom in South-South Nigeria. The fifty-six teachers who taught these students were trained in the ABL approach, and 308 students of 20 teachers were randomly selected to form the sample for the study. The teachers completed the "Basic Science and Technology Teachers Activity-Based Learning Evaluation Scale” (BSTTABLES) which elicited their response to items on their ability to apply the ABL approach and their evaluation of their students' cognitive learning ability as they apply the ABL approach in teaching BST subjects. Analysis of the data generated revealed that the teachers were highly able to apply the ABL approach and the students responded favorably to it, although their scarcity of resources for class activities. According to the teachers’ evaluation, their students improved in the cognitive learning outcomes of Recall, Comprehension, and Application, which were high when ABL was applied. While there was only slight improvement in the higher-order cognitive skills. The study concludes that the application of ABL leads to significant enhancement in the cognitive learning outcomes of BST students. It recommends continuous training, retraining and support of teachers to ensure the effective application of the ABL approach.  Article visualizations

Ergocalciferol in New-onset Type 1 diabetes: A Randomized Controlled Trial

Background: The impact of the anti-inflammatory and immunomodulatory actions of Vitamin D on the duration of partial clinical remission (PR) in youth with type 1 diabetes (T1D) is unclear. Objective: To determine the effect of adjunctive ergocalciferol on residual β-cell function (RBCF) and PR in youth with newly-diagnosed T1D who were maintained on a standardized insulin treatment protocol. Hypothesis: Ergocalciferol supplementation increases RBCF and prolongs PR. Methods: A 12-month randomized, double-blind, placebo-controlled trial of 50,000 IU of ergocalciferol per week for 2 months, and then once every 2 weeks for 10 months, versus placebo in 36 subjects of ages 10-21years(y), with T1D ofmonths, and a stimulated C-peptide (SCP) level of ≥0.2nmol/L (≥0.6ng/mL). The ergocalciferol group had 18 randomized subjects (10m/ 8f), mean age 13.3±2.8y; while the control group had 18 subjects (14m/4f), age 14.3±2.9y. Results: The ergocalciferol treatment group had significantly higher serum 25-hydroxyvitamin D at 6 months (p=0.01) and 9 months (p=0.02) than the placebo group. At 12 months, the ergocalciferol group had a significantly lower serum TNF-α concentration (p=0.03). There were no significant differences between the groups at each timepoint from baseline to 12 months for SCP concentration (p=0.08), HbA1c (p=0.09), insulin-dose-adjusted A1c (IDAA1c), or total daily dose of insulin. Temporal trends for rising HbA1c (p=0.044) and IDAA1c (p=0.015) were significantly blunted in the ergocalciferol group. Conclusions: Ergocalciferol significantly reduced serum TNF-α concentration and the rates of increase in both A1c and IDAA1c suggesting a protection of RBCF and PR in youth with newly-diagnosed T1D

Socioeconomic dynamism and the growth of baby factories in Nigeria

Abstract: Illegally breeding babies for marketing purposes otherwise known as “infant commodification” is increasing in Nigeria. This menace is a vice that threatens the lives and wellbeing of babies, young girls, and women. This article investigates through an in-depth review of scholarly publication and media coverages the factors that have contributed to the emergence and growth of the illicit industry in Nigeria. It examines the role of cultural beliefs, social attitudes, and norms as well as the harsh economic conditions of the nation as factors playing pivotal roles in the continual growth of baby farming in Nigeria. Some of these sociocultural factors are social stigmatization of pregnancy outside wedlock, stigmatization of adopted children, and the importance attached to fertility and the demonization of childlessness. The article draws on Emile Durkheim anomie theory and Chambers dimensions of poverty to explain how breakdown within the nation’s socioeconomic structure has a concomitant impact in breading social vices. It concludes by recommending that there is a need to jettison stigmatizing sociocultural beliefs within the nation’s social fabrics. Responsive attitude toward family reproductive issues should be encouraged and finally the activities of health care providers, operators of nongovernmental organizations taking custody of babies and young girls be properly monitored. As well, stringent punishment be meted out to apprehended operators of these baby farms to serve as deterrent to others

Growth characteristics in individuals with osteogenesis imperfecta in North America: results from a multicenter study.

PurposeOsteogenesis imperfecta (OI) predisposes people to recurrent fractures, bone deformities, and short stature. There is a lack of large-scale systematic studies that have investigated growth parameters in OI.MethodsUsing data from the Linked Clinical Research Centers, we compared height, growth velocity, weight, and body mass index (BMI) in 552 individuals with OI. Height, weight, and BMI were plotted on Centers for Disease Control and Prevention normative curves.ResultsIn children, the median z-scores for height in OI types I, III, and IV were -0.66, -6.91, and -2.79, respectively. Growth velocity was diminished in OI types III and IV. The median z-score for weight in children with OI type III was -4.55. The median z-scores for BMI in children with OI types I, III, and IV were 0.10, 0.91, and 0.67, respectively. Generalized linear model analyses demonstrated that the height z-score was positively correlated with the severity of the OI subtype (P < 0.001), age, bisphosphonate use, and rodding (P < 0.05).ConclusionFrom the largest cohort of individuals with OI, we provide median values for height, weight, and BMI z-scores that can aid the evaluation of overall growth in the clinic setting. This study is an important first step in the generation of OI-specific growth curves

Exercise has a positive impact on bone mineral density in seropositive human immunodeficiency virus: do health professionals know?

Introduction: Despite the concomitant negative effects of human immunodeficiency virus on bone mineral density in HIV-infected persons, studies on knowledge of effect of exercise on this health parameter in HIV population among health professionals seem unavailable. This study therefore examined knowledge on effect of exercise on BMD in HIV-infected persons among health professionals. Material and methods: This cross-sectional survey employed researcher designed, experts - validated questionnaire to enroll 434 respondents. The reliability coefficient “r” of the questionnaire was 0.75 with 92% response rate. Descriptive and inferential statistics were used to summarize and analyze the data respectively. The alpha value was set at 0.05. Results: Age range and mean age in years of the respondents were 21–59 and 35.88 ± 9.09 respectively; age group of 30–39 years predominated (45.3%). Males were in preponderance (52.4%), and most (74.4%) were married; while majority (54.7%) were nurses. Substantial proportion (54.2%) had less than good knowledge on the subject examined in this study. Significant difference (p 0.05). Conclusions: Knowledge on effect of exercise on BMD in HIV infected persons among health professionals was surprisingly below expectation, and therefore should be seen as a cause for concerned exercise scientists and public health experts

Assessment of the efficacy and toxicity of 131I-metaiodobenzylguanidine therapy for metastatic neuroendocrine tumours

131I-metaiodobenzylguanidine (131I-MIBG) is a licensed palliative treatment for patients with metastatic neuroendocrine tumours. We have retrospectively assessed the consequences of 131I-MIBG therapy in 48 patients (30 gastroenteropancreatic, 6 pulmonary, 12 unknown primary site) with metastatic neuroendocrine tumours attending Royal Liverpool University Hospital between 1996 and 2006. Mean age at diagnosis was 57.6 years (range 34–81). 131I-MIBG was administered on 88 occasions (mean 1.8 treatments, range 1–4). Twenty-nine patients had biochemical markers measured before and after 131I-MIBG, of whom 11 (36.7%) showed >50% reduction in levels post-therapy. Forty patients had radiological investigations performed after 131I-MIBG, of whom 11(27.5%) showed reduction in tumour size post-therapy. Twenty-seven (56.3%) patients reported improved symptoms after 131I-MIBG therapy. Kaplan–Meier analysis showed significantly increased survival (P=0.01) from the date of first 131I-MIBG in patients who reported symptomatic benefit from therapy. Patients with biochemical and radiological responses did not show any statistically significant alteration in survival compared to non-responders. Eleven (22.9%) patients required hospitalisation as a consequence of complications, mostly due to mild bone marrow suppression. 131I-MIBG therefore improved symptoms in more than half of the patients with metastatic neuroendocrine tumours and survival was increased in those patients who reported a symptomatic response to therapy

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. // Methods: We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung's disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. // Findings: We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung's disease) from 264 hospitals (89 in high-income countries, 166 in middle-income countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in low-income countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. // Interpretation: Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between low-income, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Newborn with klinefelter syndrome and posterior urethral valves

We describe the case of a 10-day-old term infant with 47,XXY, in association with posterior urethral valves, a right ectopic ureter, a right dysplastic kidney, left hydronephrosis, cryptorchidism, and encephalomalacia. The renal anomaly was diagnosed prenatally by ultrasonography, and additional evaluation was performed after birth. Urinary tract anomalies are uncommon in Klinefelter syndrome. Unilateral and bilateral renal agenesis have been described. We describe, to our knowledge, the first case of posterior urethral valves, ectopic ureter, and encephalomalacia in association with 47,XXY
