The Impact of Interactive Video On the Academic Achievement Among First Grade Secondary School Students

This study has been conducted to assess The Impact of Teaching by using Interactive Video on the Academic Achievement on computer subject of first year secondary , for Wadi Al Dawasir Province. The research sample consisted of (48) students divided into two groups, experimental and control groups. The experimental group studied the subject using Interactive Video , while the control group used the Linear Video approach as a method of instruction. In order to achieve the above-mentioned purpose of the study, the researcher has designed the tool of the study which is an academic achievement test of 3 levels of Bloom\u27s Taxonomy, individually and also in the overall achievement test. In order to assess or evaluate whether the interactive video had an impact on the students\u27 academic achievement, a t-test was performed for two independent samples while ETA squared test as a measure of the impact size. The research findings indicated statistically non-significant differences (a= 0.05) between the two groups in (Remembering) level, while there were statistically significant differences at (0.05) in the (comprehension and implementation) level, and the overall achievement test result was in favor of the experimental group. Based on the findings of the study, the researcher has made some recommendations and suggestions for integrating “Interactive Video” as a method of instruction into class room, arguing that it can help to raise academic achievement in the computer subject among secondary school level students, as well as the importance of developing applications and computer software based on Interactive Video should be encouraged.

Cytogenetic Prognostication Within Medulloblastoma Subgroups

PURPOSE: Medulloblastoma comprises four distinct molecular subgroups: WNT, SHH, Group 3, and Group 4. Current medulloblastoma protocols stratify patients based on clinical features: patient age, metastatic stage, extent of resection, and histologic variant. Stark prognostic and genetic differences among the four subgroups suggest that subgroup-specific molecular biomarkers could improve patient prognostication. PATIENTS AND METHODS: Molecular biomarkers were identified from a discovery set of 673 medulloblastomas from 43 cities around the world. Combined risk stratification models were designed based on clinical and cytogenetic biomarkers identified by multivariable Cox proportional hazards analyses. Identified biomarkers were tested using fluorescent in situ hybridization (FISH) on a nonoverlapping medulloblastoma tissue microarray (n = 453), with subsequent validation of the risk stratification models. RESULTS: Subgroup information improves the predictive accuracy of a multivariable survival model compared with clinical biomarkers alone. Most previously published cytogenetic biomarkers are only prognostic within a single medulloblastoma subgroup. Profiling six FISH biomarkers (GLI2, MYC, chromosome 11 [chr11], chr14, 17p, and 17q) on formalin-fixed paraffin-embedded tissues, we can reliably and reproducibly identify very low-risk and very high-risk patients within SHH, Group 3, and Group 4 medulloblastomas. CONCLUSION: Combining subgroup and cytogenetic biomarkers with established clinical biomarkers substantially improves patient prognostication, even in the context of heterogeneous clinical therapies. The prognostic significance of most molecular biomarkers is restricted to a specific subgroup. We have identified a small panel of cytogenetic biomarkers that reliably identifies very high-risk and very low-risk groups of patients, making it an excellent tool for selecting patients for therapy intensification and therapy de-escalation in future clinical trials

Role of environmental toxicants in the development of hypertensive and cardiovascular diseases

The incidence of hypertension with diabetes mellitus (DM) as a co-morbid condition is on the rise worldwide. In 2000, an estimated 972 million adults had hypertension, which is predicted to grow to 1.56 billion by 2025. Hypertension often leads to diabetes mellitus that strongly puts the patients at an increased risk of cardiovascular, kidney, and/or atherosclerotic diseases. Hypertension has been identified as a major risk factor for the development of diabetes; patients with hypertension are at two-to-three-fold higher risk of developing diabetes than patients with normal blood pressure (BP). Causes for the increase in hypertension and diabetes are not well understood, environmental factors (e.g., exposure to environmental toxicants like heavy metals, organic solvents, pesticides, alcohol, and urban lifestyle) have been postulated as one of the reasons contributing to hypertension and cardiovascular diseases (CVD). The mechanism of action(s) of these toxicants in developing hypertension and CVDs is not well defined. Research studies have linked hypertension with the chronic consumption of alcohol and exposure to metals like lead, mercury, and arsenic have also been linked to hypertension and CVD. Workers chronically exposed to styrene have a higher incidence of CVD. Recent studies have demonstrated that exposure to particulate matter (PM) in diesel exhaust and urban air contributes to increased CVD and mortality. In this review, we have imparted the role of environmental toxicants such as heavy metals, organic pollutants, PM, alcohol, and some drugs in hypertension and CVD along with possible mechanisms and limitations in extrapolating animal data to human

Knowledge, perceptions, and readiness of telepharmacy among community pharmacists

Telepharmacy is a practical part of telemedicine that refers to providing pharmaceutical services within the scope of the pharmacist's obligations while maintaining a temporal and spatial distance between patients, users of health services, and healthcare professionals. The present study was a cross-sectional study conducted among community pharmacists in Saudi Arabia between March and May 2022 to assess their knowledge, perceptions, and readiness for telepharmacy. The survey was filled out by 404 respondents. The majority of respondents were male (59.90%) and the age of more than half of them was between 30 and 39 years old (54.46%). Most participants worked in urban areas (83.66%), and 42.57% had less than five years of experience in a pharmacy. Most participants agreed that telepharmacy is available in Saudi Arabia (82.67%). Approximately 70% of pharmacists felt that telepharmacy promotes patient medication adherence, and 77.72% agreed that telepharmacy increases patient access to pharmaceuticals in rural areas. More than 72% of pharmacists said they would work on telepharmacy initiatives in rural areas for free, and 74.26% said they would work outside of usual working hours if necessary. In the future, this research could aid in adopting full-fledged telepharmacy pharmaceutical care services in Saudi Arabia. It could also help academic initiatives by allowing telepharmacy practice models to be included as a topic course in the curriculum to prepare future pharmacists to deliver telepharmacy services
