Exploring the relationship between peritraumatic dissociative experiences, post-traumatic stress disorder, stigma, and fear: A three-wave study during the COVID-19 pandemic.

COVID-19 has emerged as a pervasive global challenge, giving rise to both significant public health concerns and a range of psychological experiences, such as fear, stigma, and post-traumatic stress disorder. Importantly, healthcare professionals have been subjected to immense mental health problems as they battle against this disease. This study aimed to investigate the mediating roles of perceived stigma, self-stigma related to COVID-19, and fear of COVID-19 in the associations between peritraumatic dissociative experiences and post-traumatic stress disorder during a three-wave COVID-19 pandemic (4th [T1], no wave [T2], and 5th [T3]) in Iran. Data were collected from healthcare professionals using the Peritraumatic Dissociative Experiences Questionnaire, Impact of Event Scale-6, Perceived Stigma Scale, Fear of COVID-19 Scale, and Self-Stigma Scale-Short. The results of structural equation modelling demonstrated positive associations between peritraumatic dissociative experiences, perceived stigma, self-stigma related to COVID-19, fear of COVID-19, and post-traumatic stress disorder across all survey waves. Moreover, the study revealed that perceived stigma, self-stigma related to COVID-19, and fear of COVID-19 acted as mediators in the association between peritraumatic dissociative experiences and post-traumatic stress disorder. The implications of these findings highlight the urgent need to address the mental health of healthcare professionals in the aftermath of a pandemic. Policy efforts should be directed towards providing adequate mental health resources and support to mitigate the psychological impact of pandemics on healthcare professionals.

The impact of oral care on oral health status and prevention of ventilator-associated pneumonia in critically ill patients.

BACKGROUND: Ventilator-associated pneumonia is one of the most common nosocomial infections which increase mortality rate and length stay of hospitalisation. Oral care would not only improve patient's oral health and well-being, but it can also reduce the incidence rate of ventilator-associated pneumonia. OBJECTIVES: The objective of this study was to identify the impact of oral care practices on oral health status of patients in intensive care unit and the incidence rate of ventilator-associated pneumonia. METHODS: This clinical trial recruited 100 participants who were randomly assigned to a control group (receiving oral care by nurses) and an intervention group (receiving systematic care by the researcher) during 2015-2016. Beck Oral Assessment Scale was used to determine the required number of times for receiving oral care with regard to patient's oral health in the intervention group. Each care included adjusting endotracheal tube cuff pressure, brushing with toothpaste, using antiseptics and moistening the lips. The oral cavity was examined using BOAS and Mucosal-Plaque Score, and Clinical Pulmonary Infection Score was used for detecting pneumonia. RESULTS: The BOAS scoring showed significant differences between the two groups from the first to fifth day (P<0.001). The mucosal-plaque index was significantly different between the two groups from the third day to fifth day (P<0.001). The incidence rate of pneumonia on the third and fifth day was 10% (5) and 14% (7) in the control group, and 4% (2) and 10% (5) in the intervention group, respectively. The Fisher test did not show significant difference (P=0.538), however, the incidence rate in the intervention group reduced compared with the control group. CONCLUSION: Although following a systematic oral care program could not significantly decrease the incidence of ventilator-associated pneumonia in critically ill patients compared to the conventional oral care practices, it significantly improved the oral health and mucosal-plaque index.
