Study of serum magnesium in acute coronary syndrome patients

There had been many studies done in the past either in-vitro or clinically indicating the possible role that Magnesium may play in acute coronary syndrome.Many studies showed the presence of hypomagnesemia in coronary artery disease and also during the attack of myocardial infarct. However there is hardly any studies done on Magnesium done in Malaysia,none with regards to coronary artery disease or acute coronary syndrome.There is a need to know whether there is hypomagnesemia in Acute Coronary Syndrome in the local population.Knowledge on this will serve as a guide on future investigations,studies and treatment of Acute Coronary Syndrome or as an adjunct of ACS treatment.To ascertain whether there is a significant level of Mg deficiency among the Acute Coronary Syndrome patients in USM hospital.To justify Mg investigations as a routine investigation together with other electrolytes investigation like Na and K. To determine any differences of serum Magnesium between ACS subgroups: STEMI,UA and NSTEMI.To form a basis for further investigations regarding Magnesium treatment in ACS patients

Effect of Nano-Al3Mg2 Addition on the Microstructure of PEEK Nanocomposite Bulk Samples Consolidated from Mechanically Milled Powders

In this investigation, the effect of the novel nano-Al3Mg2 particles addition on the microstructure of polyetheretherketone (PEEK) polymer matrix nanocomposite was studied. Bulk nanocomposite samples were fabricated by consolidation of ball milled composite powders through hot pressing method. The structural evolutions of mechanically milled powders as well as consolidated nanocomposites were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM) equipped with an energy dispersive X-ray analyzer (EDX). The results showed that, although increasing the amount of β-Al3Mg2 nanoparticles up to 5 vol. % results in no chemical interaction, a low degree of PEEK crystallization, reduction in powder particle size, homogeneous distribution and well bonding of nanoparticles in the PEEK matrix but the tendency for agglomeration and porosity formation increases in comparison with 3 vol% of β-Al3Mg2.

Students‘ Learning and Study Strategies in Isfahan University of Medical Sciences and their relationship with Test Anxiety

Introduction: Test anxiety is a common problem among school and university students. Learning and study strategies as well as stress management strategies can be effective on students’ success and academic achievement .In this study, learning and study strategies, and their relationship with test anxiety has been investigated among students of Isfahan University of Medical Sciences. Methods: This descriptive cross sectional study was conducted on 200 students in Isfahan University of Medical Sciences in May, 2009. Sampling method was Quota and the population studied included BS students of nursing and midwifery, medical library and information science, nutrition and health service management. All students completed Veinstein learning and study strategies questionnaire and Sarason test anxiety inventory. Then, the relationship between the scores was investigated. Data were analyzed by statistical tests of Students-T, ANOVA and Pearson correlation through SPSS version 15. Results: The results showed that the mean scores of 10 domains were as attitude 29, motivation 27, time management 26, anxiety management15, concentration 27, information processing 28, selecting main idea 30, study aids 25, self testing 23, test strategies for learning and studying strategies questionnaire 29. Also, the level of test anxiety was light in 37% of students, moderate in 38.5% and severe in 24.5%. There was a reverse and significant association between all above domains of learning and study strategies and test anxiety (p 0/05). Conclusion: According to the reverse and significant association between using learning and study strategies and test anxiety, these strategies can be taught as a way to decrease test anxiety

Randomized trial of psychological interventions to preventing postpartum depression among Iranian first-time mothers

Background: The current study was conducted to examine the effect of cognitive behavior therapy on the reduction postpartum mood disorder and increasing the self-esteem of at-risk Iranian mothers. Methods: In this quasi-experimental study, 135 at-risk mothers were selected from the population by means of cluster sampling and randomly assigned into one of two groups: Intervention (n = 64), or control (n = 71). The control group received usual medical care, and the intervention group received an eight sessions′ cognitive behavior program during pregnancy. Assessments were administered at two time points (pretest at the beginning of the third trimester and posttest at 2 weeks postpartum). Beck anxiety, beck depression, Edinburgh postpartum depression, (PPD) Coopersmith self-esteem, and religious attitude questionnaire were used to collect data. Results: The mean age of participants was 25.8 ± 3.7 years. One-third of them had either bachelor or higher degrees in education (33%). About two-third of participants were unemployment with similar distribution in both the groups (intervention = 80%, control = 83%). The majority (70%) of the participants had cesarean section deliveries. There were no statistically significant differences respects to sociodemographic characteristics between the control and intervention groups (P > 0.05). The multivariate analysis of covariance results showed that the average scores of PPD were reduced significantly in the intervention group (P < 0.001). Also while the mean score of anxiety in the intervention group decreased from 23.31 (standard error [SE] =12.11) to 16.64 (SE = 8.33) and self-esteem increased from 29.09 (SE = 3.51) to 31.81 (SE = 2.76), no change was statistically significant in comparison to the control group. Conclusions: According to the findings of the present study, cognitive behavior intervention is effective in reducing PPD in at-risk mothers

An international, stepped wedge, cluster-randomized trial investigating the 0/1-h algorithm in suspected acute coronary syndrome in Asia: the rational of the DROP-Asian ACS study

Abstract Background More than half of the world’s population lives in Asia. With current life expectancies in Asian countries, the burden of cardiovascular disease is increasing exponentially. Overcrowding in the emergency departments (ED) has become a public health problem. Since 2015, the European Society of Cardiology recommends the use of a 0/1-h algorithm based on high-sensitivity cardiac troponin (hs-cTn) for rapid triage of patients with suspected non-ST elevation acute coronary syndrome (NSTE-ACS). However, these algorithms are currently not recommended by Asian guidelines due to the lack of suitable data. Methods The DROP-Asian ACS is a prospective, stepped wedge, cluster-randomized trial enrolling 4260 participants presenting with chest pain to the ED of 12 acute care hospitals in five Asian countries (UMIN; 000042461). Consecutive patients presenting with suspected acute coronary syndrome between July 2021 and Apr 2024 were included. Initially, all clusters will apply “usual care” according to local standard operating procedures including hs-cTnT but not the 0/1-h algorithm. The primary outcome is the incidence of major adverse cardiac events (MACE), the composite of all-cause death, myocardial infarction, unstable angina, or unplanned revascularization within 30 days. The difference in MACE (with one-sided 95% CI) was estimated to evaluate non-inferiority. The non-inferiority margin was prespecified at 1.5%. Secondary efficacy outcomes include costs for healthcare resources and duration of stay in ED. Conclusions This study provides important evidence concerning the safety and efficacy of the 0/1-h algorithm in Asian countries and may help to reduce congestion of the ED as well as medical costs
