Analysis of the adverse events following the mRNA-1273 COVID-19 vaccine

OBJECTIVE: This study aims to characterize the adverse events (AEs) following the administration of the mRNA-1273 COVID-19 vaccine from the Vaccine Adverse Event Reporting System (VAERS) data.METHODS: In this case/non-case analysis, reports between 1 January 2021, and 27 October 2022, were extracted from VAERS. AEs were defined as preferred terms (PTs) by Medical Dictionary for Regulatory Activities (MedDRA) terminology. Disproportionality analyses were conducted to calculate the reporting odds and proportional reporting ratios. The Bayesian approach was used to calculate information component (IC) values and Empirical Bayesian Geometric Mean scores for all the AEs detected.RESULTS: 186 MedDRA PTs compromising 702,495 AEs associated with the mRNA-1273 vaccine were identified. Three statistically significant signals were identified for general and systemic AEs, administration site conditions, and product issues. Cardiac disorders were rarely reported, the most common being; 489 reports for 'myocarditis' (19.44%), 475 for 'acute myocardial infarction' (18.88%), 457 for 'myocardial infarction' (18.16%), 290 for 'bradycardia' (11.53%) and 281 for 'pericarditis' (11.17%).CONCLUSIONS: The most frequently identified AEs following mRNA-1273 vaccination agree with those listed within the Summary of Product Characteristics. In addition, disproportionality analysis did not find any statistically significant signals for myocarditis or pericarditis.</p

Growth, Structural and Micro hardness studies of KSbF4 and K2SbF5 crystals

Interest in Potassium Fluoro Antimonate crystals has been increased for the last four decades due its superionic conduction and its unusual electro-optic properties. Potassium tetra fluoro antimonate (KSbF4) and Potassium penta fluoro antimonite (K2SbF5) crystals have been grown by slow evaporation method. KSbF4 crystallizes into orthorhombic structure with a space group Pmmn. K2SbF5 belongs to orthorhombic crystal system with a space group Cmcm.nbsp Micro indentation analysis on these crystals indicates that they are moderately softer substances. Both crystals revealed reverse indentation size effect (RISE). Variation of stiffness constant with load has been discussed. Yield strength for KSbF4 and K2SbF5 crystals have been found out as 16.72 and 16.941 MPa respectively.nbs

Evidence-based health policymaking in Iraqi Kurdistan: Facilitators and barriers from the perspectives of policymakers and advisors

Background and objective: Evidence from research is underutilized in policy and practice in the majority of developing countries including Iraq. This aim of this study was to assess the role of research in health policy making in Iraqi Kurdistan context and identify the main barriers and facilitators for enhancing such role. Methods: This cross-sectional survey was carried out between November 2013 and March 2014 in the three governorates of the Iraqi Kurdistan Region, Erbil, Duhok and Sulaimaniyah. The study participants included 10 key health informants and three health advisors. Two types of combined questionnaires for health policy makers and health advisors were used for data collection. Results: Conferences and seminars were the main sources of scientific evidences identified by health policymakers (80%), followed by consultants (70%). Different jargons/discourse was the main obstacle in consulting researchers (90%), followed by lack of tradition in collaborating (70%). Collection of specialists/advisors, followed by professional associations, scientific committees and international organizations/UN agencies were the main groups identified by health advisors to build bridges between the scientific community and policymakers. Conclusion: Policymakers very rarely consult researchers directly in their decision making. There is poor networking among researchers, policy-makers, practitioners and representatives from civil society which has its negative impact on evidence-based policymaking. There is obviously a lack of any sort of program of funded research that can inform policymaking

International Perspectives on the Legal Environment for Selection

Perspectives from 22 countries on aspects of the legal environment for selection are presented in this article. Issues addressed include (a) whether there are racial/ethnic/religious subgroups viewed as "disadvantaged,” (b) whether research documents mean differences between groups on individual difference measures relevant to job performance, (c) whether there are laws prohibiting discrimination against specific groups, (d) the evidence required to make and refute a claim of discrimination, (e) the consequences of violation of the laws, (f) whether particular selection methods are limited or banned, (g) whether preferential treatment of members of disadvantaged groups is permitted, and (h) whether the practice of industrial and organizational psychology has been affected by the legal environmen

Safety outcomes associated with the moderna COVID-19 vaccine (mRNA-1273): a literature review

Introduction Current safety data from Phase 3 clinical trials have concluded that apart from transient local and systemic reactions, no safety concerns were identified for the Moderna COVID-19 vaccine (mRNA-1273). However, Phase 3 studies are insufficient to detect rare adverse events (AEs). A literature search of the two major electronic databases, Embase and PubMed, was performed to enable the identification and characterization of all relevant articles from December 2020 to November 2022. Areas Covered This narrative review summarizes the key safety outcomes associated with the mRNA-1273 vaccine to inform healthcare decisions and increase public awareness of mRNA-1273 vaccine safety. The primary adverse events (AEs) reported within a diverse population, receiving the mRNA-1273 vaccine, were; localized injection site pain, fatigue, headache, myalgia, and chills. In addition, the mRNA-1273 vaccine was also associated with; less than a 1-day change in the menstrual cycle, a 10-fold higher risk of myocarditis and pericarditis within young males aged 18–29 years and increased levels of anti-polyethylene glycol (PEG) antibodies. Expert Opinion The transient nature of commonly observed AEs and the rare occurrence of severe events within mRNA-1273 recipients show no significant safety concerns which should prevent vaccination. However, large-scale epidemiological studies with longer follow-up periods are required to surveillance rare safety outcomes

The impact of COVID-19 related lockdown on the prevalence of spousal violence against women in Kurdistan region of Iraq

There is increasing concern about the impact of the COVID-19 pandemic and the lockdown’s social and economic consequences on gender-based violence. This study aimed to assess the impact of the COVID-19 pandemic on gender-based violence by comparing the prevalence of spousal violence against women before and during the COVID-19 related lockdown periods. This study was conducted in the Kurdistan Region of Iraq using a self-administered online questionnaire survey after the COVID-19 lockdown period in June 2020. Data were collected from a sample of 346 married women about the occurrence, frequency, and forms of spousal violence before and during the lockdown period. Significant increases in violence were observed from the pre-lockdown period to the lockdown period for any violence (32.1% to 38.7%, p = .001), emotional abuse (29.5% to 35.0%, p = .005), and physical violence (12.7% to 17.6%, p = .002). Regarding emotional abuse, humiliation (24.6% to 28.3%, p = .041) and scaring or intimidation (14.2% to 21.4%, p < .001) significantly increased during the lockdown. For physical violence, twisting the arm or pulling hair (9.0% to 13.0%, p = .004) and hitting (5.2% to 9.2%, p = .003) significantly increased during the lockdown. Forcing to have sexual intercourse also significantly increased during lockdown (6.6% to 9.5%., p = .021). The concerned authorities and women’s rights organizations should collaborate to enhance the prevention of violence against women. An effective prevention strategy should emphasize recognizing and acknowledging the extent of the problem, raising awareness about the problem and the available resources to address it, and ensuring social and economic stability. Lessons learned about the increased prevalence of spousal violence against women during the COVID-19 pandemic and the need to adopt appropriate strategies to prevent and address it will be valuable for similar future crises
