The Effect of Happiness Training on Psychological Well-Being in Patients with Thalassaemia Major: A quasi-experimental study.

Objectives: This study aimed to determine the effects of happiness training on the psychological well-being of thalassaemia major (TM) patients. TM is a chronic haematological disease that can have profound effects on patients' mental health and psychological well-being. Methods: This quasi-experimental study with a pre/post-test design was performed on 52 patients with TM attending the thalassaemia care centre of Imam Khomeini Hospital in Zabol city, Iran, from August to December 2020. The patients were randomly categorised into experimental and control groups. In the experimental group, happiness training was performed in eight sessions, each for 60 minutes. The control group received routine care. The data collection tool employed was the Ryff's Scale of Psychological Well-Being. Data were analysed by SPSS 16 using descriptive (mean ± standard deviation) and inferential (paired and independent t-test) statistics. Results: Regarding the psychological well-being score at the pre-test stage, there was no statistically significant difference between the intervention (74.92 ± 6.36) and control (74.57 ± 5.83) groups (P = 0.83). After the intervention, however, a statistically significant difference was observed between the two groups in terms of psychological well-being (P <0.001). Additionally, a statistically significant difference was seen one comparing the psychological well-being score between the pre- and post-intervention phases in the experimental (P = 0.01) but not control (P = 0.12) group. Conclusion: The results of this study showed that happiness training improved TM patients' psychological well-being. Therefore, this type of training can be used as an appropriate educational strategy to improve the psychological well-being in these patients.

Global Prevalence and Device Related Causes of Needle Stick Injuries among Health Care Workers: A Systematic Review and Meta-Analysis.

Background: Healthcare workers (HCWs) suffer more than 2 million occupational needle-stick injuries (NSIs) annually. Goal: To determine the global prevalence and causes of NSIs among HCWs. Methods: In this systematic review and meta-analysis, three databases (PubMed, Web of science, and Scopus) were searched for reports from January 1, 2000 to December 31, 2018. The random effects model was used to determine the prevalence of NSIs among HCWs. Hoy et al.'s instrument was employed to evaluate the quality of the included studies. Findings: A total of 87 studies performed on 50,916 HCWs in 31 countries worldwide were included in the study. The one-year global pooled prevalence of NSIs among HCWs was 44.5% (95% CI: 35.7, 53.2). Highest prevalence of NSIs occurred in the South East Asia region at 58.2% (95%, CI: 36.7, 79.8). By job category, prevalence of NSIs was highest among dentists at 59.1% (95% CI: 38.8, 79.4), Hypodermic needles were the most common cause of NSIs at 55.1% (95% CI: 41.4, 68.9). Conclusion: The current high prevalence of NSIs among HCWs suggests need to improve occupational health services and needle-stick education programs globally.

Frequency of Cataract in Iran: A Meta-Analysis and Systematic Review.

PURPOSE: Cataract is the leading cause of blindness and the second cause of low vision in the world. In the world, Asia has the highest number of blind population. The aim of the present systematic review and meta-analysis was to assess the frequency of clinical cataracts in Iran. MATERIALS AND METHODS: The frequency of clinical cataract was defined based on the international criteria and the measured outcome of the disease. Study selection, data extraction, and quality assessment were performed by two independent reviewers. We explored PubMed, Google Scholar, ISI Web of Science, and national databases (scientific information database, Magiran) to evaluate the clinical cataract of cataract in the Iranian populations from 1995 to July 2017. Statistical analysis was performed using STATA 14.0 software. RESULTS: Of 283 studies, 27 studies utilized meta-analysis. In 2017, the pooled overall frequency of clinical cataract in 59668 people was 9.27% (95% confidence interval [CI]: 8.09, 10.45, I2 = 98.82%). Based on subgroup analysis, in the random effect method, the frequency of clinical cataract in males and females were 8.03% (CI: 6.78, 9.28) and 8.32% (CI: 7.08, 9.55), respectively. CONCLUSION: Regarding the high frequency of clinical cataract in Iran, it seems that paying attention to the results of the current study and the application of international policy plans may contribute to better cataract control in Iran.
