Activation of GPER1 by G1 prevents PTSD-like behaviors in mice: Illustrating the mechanisms from BDNF/TrkB to mitochondria and synaptic connection.

BACKGROUND: G1 is a specific agonist of G protein-coupled estrogen receptor 1 (GPER1), which binds and activates GPER1 to exert various neurological functions. However, the preventive effect of G1 on post-traumatic stress disorder (PTSD) and its mechanisms are unclear. OBJECTIVE: To evaluate the protective effect of G1 against synaptic and mitochondrial impairments and to investigate the mechanism of G1 to improve PTSD from brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB) signaling. METHODS: This study initially detected GPER1 expression in the hippocampus of single prolonged stress (SPS) mice, utilizing both Western blot and immunofluorescence staining. Subsequently, the effects of G1 on PTSD-like behaviors, synaptic, and mitochondrial functions in SPS mice were investigated. Additionally, the involvement of BDNF/TrkB signaling involved in the protection was further confirmed using GPER1 antagonist and TrkB inhibitor, respectively. RESULTS: The expression of GPER1 was reduced in the hippocampus of SPS mice, and G1 treatment given for 14 consecutive days significantly improved PTSD-like behaviors in SPS mice compared with model group. Electrophysiological local field potential (LFP) results showed that G1 administration for 14 consecutive days could reverse the abnormal changes in the gamma oscillation in the CA1 region of SPS mice. Meanwhile, G1 administration for 14 consecutive days could significantly improve the abnormal expression of synaptic proteins, increase the expression of mitochondria-related proteins, increase the number of synapses in the hippocampus, and ameliorate the damage of hippocampal mitochondrial structure in SPS mice. In addition, G15 (GPER1 inhibitor) and ANA-12 (TrkB inhibitor) blocked the ameliorative effects of G1 on PTSD-like behaviors and aberrant expression of hippocampal synaptic and mitochondrial proteins in SPS mice and inhibited the reparative effects of G1 on structural damage to hippocampal mitochondria, respectively. CONCLUSION: G1 improved PTSD-like behaviors in SPS mice, possibly by increasing hippocampal GPER1 expression and promoting BDNF/TrkB signaling to repair synaptic and mitochondrial functional impairments. This study would provide critical mechanism for the prevention and treatment of PTSD.

[Poor sleep quality contributes to occurrence of posttraumatic stress disorder in trauma patients].

OBJECTIVE: To evaluate the impact of poor sleep quality on occurrence of post-traumatic stress disorder (PTSD) in trauma patients. METHODS: We prospectively recruited 256 trauma patients hospitalized in 4 general hospitals in Zunyi during the period from October, 2021 to November, 2022, and 226 of the participants completed the PTSD survey and assessment. The patients' sleep quality within a month before trauma was estimated using Pittsburgh Sleep Quality Index (PSQI), and their sleep quality within 7 days after admission was monitored by smart bracelet sleep monitoring; the PTSD Checklist-Civilian Version (PCL-C) was used to detect the occurrence of PTSD during the follow-up. RESULTS: The detection rate of PTSD in the patients was 19.47% at 1 month and 17.61% at 3 months after trauma. The patients who developed PTSD had poorer sleep quality before the trauma, as shown by significantly higher PSQI scale scores (P < 0.001), than those without PTSD, and they showed a sleep abnormality rate as high as 72.73% prior to PTSD onset. Within 7 days after admission, the patients developing PTSD had lower sleep quality scores with more frequent night awakenings (P < 0.05). A 1 month and 3 months after trauma, the patients with PTSD had significantly higher PSQI scores than those without PTSD (P < 0.05). CONCLUSION: PTSD is more likely to occur in trauma patients with poor sleep quality before trauma.

Trauma-informed support after a complicated childbirth - An early intervention to reduce symptoms of post-traumatic stress, fear of childbirth and mental illness.

OBJECTIVE: Women who experience obstetric interventions and complications during childbirth have an increased risk of developing postnatal post-traumatic stress and mental illness. This study aimed to test the effect of a trauma-informed support programme based on psychological first aid (PFA) to reduce the mothers' symptoms of stress, fear of childbirth (FOC), anxiety and depression after a complicated childbirth. METHODS: The study population consisted of women ≥ 18 years old who had undergone a complicated childbirth (i.e. acute or emergency caesarean section, vacuum extraction, child in need of neonatal care, manual placenta removal, obstetric anal sphincter injury, shoulder dystocia or major haemorrhage (>1000 ml)). A total of 101 women participated in the study, of whom 43 received the intervention. Demographic questions and three self-assessment instruments measuring stress symptoms, FOC, anxiety and depression were answered one to three months after birth. RESULTS: The women in the intervention group scored significantly lower on the stress symptom scale, with a halved median score compared to the control group. There was no significant difference between the groups regarding FOC, depression and anxiety. CONCLUSION: Our results indicate that this PFA-based support programme might reduce post-traumatic stress symptoms in women who have gone through a complicated childbirth. With further studies in a larger population, this support programme has the potential to contribute to improved maternal care optimizing postnatal mental health.

Maternity support workers' experiences of workplace trauma and post-traumatic stress symptoms.

BACKGROUND: Maternity support workers (MSWs) are now a key part of the maternity workforce. They work in environments with potential exposure to traumatic events, but little is known about their rates of exposure or psychological responses. OBJECTIVES: We aimed to identify the proportion of MSWs reporting exposure to a traumatic work event and consequential rates of post-traumatic stress disorder (PTSD). We also aimed to identify factors associated with PTSD and to describe levels of burnout, empathy, and functional impairment, and to explore their potential associations with PTSD symptoms. METHODS: MSWs were recruited via the Royal College of Midwives newsletter, which is sent to all MSW members, and via social media on the College MSW Facebook page. Participants completed an online survey. They provided information on demographic details, job role, and exposure to traumatic events, and completed questionnaires covering PTSD symptoms related to work events, related functional impairment, burnout, and empathy. Data were analysed via correlations and multiple regression. FINDINGS: Of 98 respondents, 88 had been exposed to a traumatic work event; 79 of these through being present and nine through hearing about traumatic events. Of those exposed, 14.8% (n = 13) participants had probable PTSD, while a further 5.7 % (n = 5) met the subclinical threshold. Over a third (35.2 %) of the sample showed high levels of emotional exhaustion, a key feature of burnout, and 27.3 % reported functional work impairment. PTSD symptoms were associated with younger age, higher empathic concern, and direct exposure to traumatic perinatal events. CONCLUSIONS AND CLINICAL IMPLICATIONS: MSWs are routinely exposed to traumatic events at work and are at risk of work-related PTSD. Younger and more empathic staff appear more at risk, although our methods could not distinguish cause and effect. It must also be noted that the survey took place during the COVID-19 pandemic, and findings could be influenced by this context. MSWs need to be routinely included in programmes to support staff in relation to trauma exposure at work.

Psycho-emotional impact of the COVID-19 pandemic on nursing professionals in Ecuador: a cross-sectional study.

AIM AND OBJECTIVES: To analyse the levels of anxiety, depression, post-traumatic stress, and burnout among nursing professionals working in the Imbabura region of Ecuador during the COVID-19 pandemic and identify the contributing socio-occupational factors. BACKGROUND: The high demand for care of COVID-19 patients led to increased work pressure on nurses, owing to increased demands for care and shortages of medical supplies and protective equipment. DESIGN: A cross-sectional study was conducted from September to December 2022 using a self-administered questionnaire addressed to nursing professionals who cared for COVID-19 patients. METHODS: The questionnaire included socio-demographic characteristics, the Spanish adaptation of Hospital Anxiety and Depression Scale (HADS-Spanish), Impact of Event Scale-Revised (IES-R) for the evaluation of post-traumatic stress disorder (PTSD), and the Spanish adaptation of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS-Spanish) for burnout assessment. Univariate and multivariate analyses were performed. RESULTS: Of the 782 participants, 88.6% had a high level of burnout (MBI-HSS-Spanish scale score > 27). Female nurses, nurses with eight-hour work shifts, and older professionals exhibited high levels of anxiety and depression. Prolonged working hours in COVID-19 patient care services were found to be a risk factor for burnout and post-traumatic stress. CONCLUSIONS: Participating nurses presented with a high level of chronic work stress and exhibited signs of anxiety and depression during the period under consideration. Providing nurses with psychological support measures and performing liaison consultations will alleviate the psychological burden on nurses. RELEVANCE TO CLINICAL PRACTICE: The study has shown that accounting for the environments where the emotional impact is greatest and how to reduce it would not only reduce anxiety, depression, and burnout in nurses but also improve the quality of care, not only in pandemic. PATIENT OR PUBLIC CONTRIBUTION: Nurses contributed to the conduct of the study by participating in the data collection via questionaries.

Heparin as a Potential Therapeutic Substance for Post-Traumatic Stress Disorder.

In sexually mature male Wistar rats with modeled post-traumatic stress disorder, personalized characteristics of neurobiological reactions in the population of predator-induced stress-resilient and stress-susceptible heparinized animals were determined. Characteristics of the systemic response of immune mechanisms, hypothalamic-pituitary-adrenal axis, behavioral manifestations, as well as basic properties of the CNS (excitation/inhibition) are presented. The study demonstrated encouraging positive results of the course administration of unfractionated heparin at a dose below the therapeutic and prophylactic doses. The inclusion of heparin drugs into the clinical practice for the treatment of post-traumatic stress disorder will not require large-scale clinical trials, because many effects of heparin as a nonspecific adaptogen are well studied. Moreover, these properties were confirmed at a higher technological level during the COVID-19 pandemic.

A Virtual Reality Simulation to Examine the Relationship Between Post-Traumatic Stress Symptoms and Decision-Making in First Responders.

First responders (FRs) are continuously exposed to critical incidents, considered traumatic events (TEs). This cumulative exposure increases the risk for post-traumatic stress disorder (PTSD). However, there is no evidence about the relationship between PTSD symptoms and emergency decision-making (EDM). The objective of this study was to examine the EDM of FRs during a virtual reality through the simulation of two emergency scenarios to collect data on the reaction time and the number of incorrect decisions. We also assessed PTSD symptoms, TE, and sociodemographics. The sample included 368 Portuguese FRs, were 295 (80.20%) males and 73 (19.80%) females, with a mean age of 33.96 (SD = 9.38). Considering the probable PTSD diagnosis according to the DSM-5, 85 (23.10%) of the FRs met the criteria. These individuals who meet the criteria exhibited higher EDM scores (M = 19.60, SD = 5.99) compared to those without probable PTSD (M = 17.87, SD = .5.66) (F(1, 360) = 5.32, p = .02, partial η2 = .015). We found that TEs had a direct effect on EDM, ß = -.16, Z = -3.74, p < .001), and the pathway of trauma-PTSD symptoms-decision-making an indirect effect, ß = .02, Z = 3.10, p = .002). Individuals exposed to more TEs demonstrated faster and more accurate decision-making in the context of EDM. However, when these individuals developed PTSD symptoms, their decision-making became slower and less accurate. The inclusion of a trauma-informed approach for FRs to prevent individual and job-related consequences is discussed.

Changes in Service Use After Participation in an Intensive Outpatient Program Among Adults With Posttraumatic Stress Disorder.

INTRODUCTION: Intensive outpatient programs (IOPs) have been shown to reduce posttraumatic stress disorder (PTSD) symptoms in veteran populations. The aim of this study was to examine the association between IOP participation and inpatient psychiatric and mental health-related emergency department (ED) encounters among patients with PTSD. METHODS: This is a retrospective cohort study among 258 adults with PTSD who participated in the IOP at Kaiser Permanente Oakland Medical Center between January 1, 2017, and December 31, 2018. The authors compared changes in inpatient psychiatric hospitalizations and mental health-related ED encounters from the year before vs after the first IOP engagement. Bivariate analyses comparing ED and inpatient utilization pre- and post-IOP engagement, stratified by sociodemographic variables were conducted using paired t-tests and McNemar's test. Conditional multivariable logistic regression was performed to assess the odds of psychiatric utilization. RESULTS: Participants were more likely to have ≥ 1 inpatient psychiatric encounter (28.7% vs 15.9%; p < 0.01) and ≥ 1 mental health-related ED encounter (24.8% vs 18.2%; p = 0.04) pre-IOP vs post-IOP. The authors' multivariable analysis demonstrated that patients experienced a 56% reduction in the odds of inpatient psychiatric encounters (adjusted odds ratio = 0.42, 95% confidence interval: 0.26-0.68, p < 0.01) and a 35% reduction in mental health-related ED encounters (adjusted odds ratio = 0.63, 95% confidence interval: 0.40-1.00, p = 0.05) post-IOP vs pre-IOP. DISCUSSION: This study demonstrated a significant reduction in inpatient psychiatric hospitalizations and mental health-related ED visits among patients with PTSD in the year following participation in an IOP. CONCLUSION: These findings support the use of IOPs for patients with PTSD to reduce the likelihood of intensive service use.

Psychological distress mediates the association between COVID-19-related discrimination and subsequent PTSD symptom severity in healthcare workers: a two-year follow-up study.

BACKGROUND: Past research has suggested a cross-sectional association between COVID-19-related discrimination and PTSD symptom severity. However, no cohort study has examined the longitudinal association that better supports causal interpretation. Also, even if such an association genuinely exists, the specific pathway remains unclear. METHODS: We conducted a two-year follow-up study, obtaining data from healthcare workers in a hospital setting. We first evaluated how COVID-19-related discrimination in 2021 was associated with subsequent PTSD symptom severity in 2023. Thereafter, we conducted causal mediation analysis to examine how this association was mediated by psychological distress in 2022, accounting for exposure-mediator interaction. Missing data were handled using random forest imputation. RESULTS: A total of 660 hospital staff were included. The fully adjusted model showed greater PTSD symptom severity in individuals who experienced any COVID-19-related discrimination compared with those without such experiences (ß, 0.44; 95% CI, 0.04-0.90). Regarding each type of discrimination, perceived discrimination was associated with greater PTSD symptom severity (ß, 0.52; 95% CI, 0.08-0.96), whereas verbal discrimination did not reach statistical significance. Psychological distress mediated 28.1%-38.8% of the observed associations. CONCLUSIONS: COVID-19-related discrimination is associated with subsequent PTSD symptom severity in healthcare workers. Psychological distress may serve as an important mediator, underscoring the potential need for interventions targeting this factor.

Posttraumatic stress disorder in the aftermath of the Turkey earthquake: exploring the role of demographics, level of exposure, and personality traits.

BACKGROUND AND OBJECTIVES: Post-Traumatic Stress Disorder (PTSD) is an important mental disorder that can develop after mass traumas such as earthquakes. In our study, we aimed to investigate the development of PTSD after the Turkey earthquake (6 February 2023) and its association with some demographic variables, personality traits, and psychological vulnerability. METHOD: 547 participants completed assessments of personality, disaster exposure, and PTSD symptoms. Multiple regression analyses were used to identify predictors of PTSD symptoms. RESULTS: PTSD scores were higher in women, single people, those with low educational level, those who witnessed someone else's injury or death, those who were injured, and those whose homes were destroyed. Physical injury, conscientiousness, marital status, income, and agreeableness predicted PTSD. Among these variables, physical injury was the strongest predictor of PTSD. CONCLUSIONS: Psychological vulnerability, conscientiousness, physical injury, employment, witnessing someone else's injury, gender, and emotional stability predicted PTSD score in a significant way. Physical injury, conscientiousness, marital status, income, agreeableness predicted PTSD in a significant way.

Case report: "Scared to deaf": medical-legal evaluation of a suspected post -traumatic stress disorder".

The case concerns the alleged failure by the resisting administration to fulfill obligations arising from the contract and employment relationship, as well as the violation of safety regulations leading to the workplace accident reported by an Airforce Sergeant. Following the accident, the soldier complains of developing barotraumatic hearing loss with tinnitus and reactive post-traumatic stress disorder to the traumatic event. The case provides an opportunity to analyze the relevance of forensic medical assessment and its integration with psychodiagnostic examination for the correct nosographic classification aimed at evaluating and quantifying biological damage.

Analysis of risk factors and construction of a prediction model for posttraumatic stress disorder among Chinese college students during the COVID-19 pandemic.

BACKGROUND: To explore the risk factors of post-traumatic stress disorder (PTSD) among Chinese college students during the COVID-19 pandemic and the construction and validation of risk prediction models. METHODS: A total of 10,705 university students were selected for the study. The questionnaire included the Generalized Anxiety Disorder 7 (GAD-7), Patient Health Questionnaire 9 (PHQ-9), PTSD Checklist for DSM-5 (PCL-5), and self-designed questionnaire. These assessments were conducted to facilitate the survey, construct the predictive model and validate the model's validity. RESULTS: Sex, left-behind experience, poverty status, anxiety score, and depression score were identified as independent risk factors influencing psychological trauma among Chinese college students during the COVID-19 pandemic, while COVID-19 infection emerged as a protective factor against psychological trauma. A column chart was constructed to visualize the six independent risk factors derived from logistic regression analysis. The Hosmer-Lemeshow test results (χ2 = 13.021, P = 0.111) indicated that the risk prediction model fitted well. The receiver operating characteristic (ROC) curve showed an area under the curve (AUC) of 0.864 in the model group and 0.855 in the validation group. The calibration curves of the model closely resembled the ideal curve. Decision curve analysis (DCA) revealed that the model provided net benefit and demonstrated good clinical utility. LIMITATIONS: The validation of the model is currently restricted to internal assessments. However, further confirmation through larger sample sizes, multicenter investigations, and prospective studies is necessary. CONCLUSIONS: The model effectively predicted PTSD risk among Chinese college students during the COVID-19 pandemic, indicating strong clinical applicability.

112 What's your emergency? Overview of mental health and sleep disorders among emergency medical dispatchers in a French 112 call center.

BACKGROUND: Emergency medical dispatchers (EMD) experience significant occupational stress. Medical dispatching includes call-taking, triage, dispatch, and providing callers gesture guidance to the victims. Every decision has a major impact on the patient's outcome. Chronic exposure to stress and potentially traumatic situations, combined with night shifts can impact the stress response and physical health of staff. OBJECTIVES: To evaluate the prevalence of mental health and sleep disorders among EMD personnel working in a 112-call center, prior to an evidence-based prevention intervention (primary outcome); and to assess the relationship between health outcomes and DM (secondary outcome). METHODS: We conducted a descriptive, monocentric study with 109 EMD. HAD Anxiety (HAD-A) and Depression (HAD-D) scores, and the PTSD checklist for DSM-5 (PCL-5) were used to explore mental health disorders. The Epworth Sleepiness Scale, and other analog scales were used to explore sleep disorders. DM resources were assessed using the Freiburg Mindfulness Inventory (FMI), and its Presence and Acceptance subscales. RESULTS: A total of 72% of the EMD working in the call center were included. Of these, 16.6% had moderate anxiety disorder, and 6.4% had an anxiety disorder (Mean HAD-A: 6.05 ± 2.88). Furthermore, 16.6% had a moderate depression disorder, and 6.4% had a depression disorder (Mean HAD-D: 4.28 ± 3.28), and 16% had symptoms of PTSD (Mean PCL-5: 17.57 ± 13.67). Turning to sleep, 39% may suffer from excessive daytime sleepiness (EDS), and 10% had confirmed EDS (Mean Epworth score 10.47 ± 4.41). Finally, 39% had moderate insomnia, and 59% had severe insomnia (Mean insomnia: 13.84 ± 5.77.). Medium-strength negative correlations were found between mental health and DM (FMI scores and sub-scores: -0.48 < r < - 0.29; 0.001 < p < 0.004); and a positive correlation was found between DM and daytime awareness (0.22 < r < 0.26; 0.01 < p < 0.03). CONCLUSION: The prevalence of depression, symptoms of PTSD, and sleep disorders in our sample of EMD is significant, and confirms findings reported in the literature. The EMD population may benefit from specific, multi-level interventions that target mindfulness, sleep, and ergonomics to improve their mental and physical health.

Use of Machine-Learning Algorithms Based on Text, Audio and Video Data in the Prediction of Anxiety and Post-Traumatic Stress in General and Clinical Populations: A Systematic Review.

Research in machine-learning (ML) algorithms using natural behavior (i.e., text, audio, and video data) suggests that these techniques could contribute to personalization in psychology and psychiatry. However, a systematic review of the current state-of-the-art is missing. Moreover, individual studies often target ML experts, and may overlook potential clinical implications of their findings. In a narrative accessible to mental health professionals, we present a systematic review, conducted in 5 psychology and 2 computer-science databases. We included 128 studies assessing the predictive power of ML algorithms using text, audio, and/or video data in the prediction of anxiety and post-traumatic stress (PTSD). Most studies (n = 87) aimed at predicting anxiety, the remainder (n = 41) focused on PTSD. They were mostly published since 2019, in computer science journals, and tested algorithms using text (n = 72), as opposed to audio or video. They focused mainly on general populations (n = 92), less on laboratory experiments (n = 23) or clinical populations (n = 13). Methodological quality varied, as did reported metrics of the predictive power, hampering comparison across studies. Two thirds of studies, focusing on both disorders, reported acceptable to very good predictive power (including high-quality studies only). Results of 33 studies were uninterpretable, mainly due to missing information. Research into ML algorithms using natural behavior is in its infancy, but shows potential to contribute to diagnostics of mental disorders, such as anxiety and PTSD, in the future, if standardization of methods, reporting of results, and research in clinical populations are improved.

A pilot study of a brief and scalable psychosocial intervention for children and adolescents following disasters.

OBJECTIVES: Following disaster exposure, a significant proportion of children/adolescents will develop levels of post-traumatic stress symptoms (PTSS) that do not meet diagnostic threshold for PTSD, but which cause ongoing distress. This paper describes the development and pilot testing of a brief, scalable, psychosocial intervention. SOLAR-Kids/Teens has been designed to be delivered by non-mental health professionals ('coaches') to children/adolescents experiencing moderate levels of PTSS following disasters. METHODS: An international collaboration of experts developed The Skills fOr Life Adjustment and Resilience (SOLAR) for Kids and Teens programs. The programs were piloted-using a pre-post mixed methods design-with 10 children and adolescents (8-18 years), with the aims of examining the feasibility of the program's delivery model as well as the program's potential usefulness. RESULTS: The pilot data indicated that after 1 day of training and with ongoing supervision, the SOLAR program was safe and feasible for coaches to deliver to children/adolescents experiencing PTSS. Coaches reported increased knowledge (p = .001), confidence (p = .001) and skills (p = .006). The programs were acceptable to coaches, children/adolescents and parents. Parents and children/adolescents reported reductions in trauma and anxiety symptoms from pre- to post-treatment, with moderate to large effect sizes. CONCLUSIONS: The preliminary findings demonstrate that the SOLAR-Kids/Teens program is feasible, acceptable and safe to be delivered by trained non-mental health professionals to children and adolescents experiencing PTSS and anxiety following disaster exposure. Randomized controlled trials are required to evaluate the efficacy of the SOLAR-Kids/Teens programs.

The mediating effect of positive expectations in the relationship between social support and post-traumatic stress disorder symptoms among parents of children with acute lymphoblastic leukemia.

PURPOSE: Parents of children with cancer are exposed to risks of developing post-traumatic stress disorder (PTSD) symptoms, but few studies have explored PTSD symptoms of Chinese parents of children with acute lymphoblastic leukemia (ALL). Our study aimed to examine the association between social support and PTSD symptoms and to examine the mediating effect of positive expectations in this relationship among parents of children with ALL. METHODS: A cross-sectional study was conducted of consecutive parents of children with ALL in the Shengjing Hospital of China Medical University. A total of 177 parents eligible for this study completed questionnaires on PTSD symptoms, perceived social support, optimism and general self-efficacy anonymously. Asymptotic and resampling strategies were used to examine how positive expectations mediated the association between perceived social support and PTSD symptoms. RESULTS: Mean score of PTSD symptoms was 37.64 ± 14.44; 29.4% of the sample scored 44 and above, 19.8% scored 50 and above. After adjusting for covariates, perceived social support was negatively associated with the total score of PTSD symptoms (ß = -0.209, p < 0.01). Positive expectations were found to mediate the relationship between perceived social support and PTSD symptoms, especially for the symptoms of avoidance and hyperarousal. CONCLUSIONS: Optimism and general self-efficacy fully mediated the association between perceived social support and PTSD symptoms. Therefore, social support and positive expectations should be included in PTSD preventions and treatments targeting Chinese parents of children with ALL.

Pain and psychopathology after intensive care unit admission.

Pain and psychopathology are observed in 18% and 55% of patients, respectively, 1 year after intensive care unit (ICU) admission. It is well known that chronic pain and psychopathology have a bidirectional relation in the general population, but it is not known whether this holds true for ICU survivors. The aim of this study was to investigate whether pain before, during and after ICU admission is related to psychopathology in ICU survivors 1 year after discharge. We performed a cohort study in a mixed ICU in the Netherlands between 2013 and 2016. At 1-year follow-up, patients completed the Hospital Anxiety and Depression Scale, the Impact of Event Scale/Impact of Event Scale-Revised, and answered standardised questions regarding pain. Psychopathology was defined as having anxiety, depressive and/or post-traumatic stress disorder symptoms. We used multivariable logistic regression analysis to evaluate the association of pain before, during and after ICU admission with psychopathology at 1 year follow-up. We included 1105 patients of whom 558 (50%) (95% confidence interval (CI) 0.48 to 0.54) had psychopathology at 1 year follow-up. Pain before ICU admission (odds ratio (OR) 1.18; 95% CI 1.10 to 1.26) and pain after ICU admission (OR 2.38; 95% CI 1.68 to 3.35) were associated with psychopathology. Pain during ICU stay was not associated with psychopathology, but the memory of insufficient pain management during ICU stay was (OR 2.19; 95% CI 1.39 to 3.45). Paying attention to pain and pain treatment experiences related to ICU admission may therefore contribute to early identification of ICU survivors at risk of psychopathology development.

A systematic review of mental health of women in fragile and humanitarian settings of the Eastern Mediterranean Region.

Background: The increasing emergencies and humanitarian challenges have worsened the mental health condition of women in the Eastern Mediterranean Region. Aim: To assess the prevalence, determinants and interventions to address mental health among women in fragile and humanitarian settings in the Eastern Mediterranean Region. Methods: Using the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines, we reviewed 59 peer-reviewed published studies (PubMed, IMEMR) and grey literature (WHO/IRIS) from January 2001 to February 2023, focusing on women's mental health in the Eastern Mediterranean Region. We then conducted a descriptive analysis of the sociodemographic characteristics. Results: Among the 59 studies reviewed, only 13 of the 48 peer-reviewed studies focused primarily on women's mental health, 11 grey literature records mostly presented grouped regional data, 11 of the 25 studies on mental health among migrants were about those taking refuge in high-income countries. The average prevalence of mental disorders from 32 cross-sectional studies on women aged 12-75 years was 49%, average prevalence of anxiety was 68%, post-traumatic stress disorder was 52%, and depression was 43%. Women exhibited higher level depression than men. Age, educational disparities, and limited access to services were important risk factors for mental health disorder. Several promising interventions emerged. Conclusion: More efforts should be made to provide customized, context-specific solutions to the mental health challenges of women in humanitarian and fragile settings in the Eastern Mediterranean Region, including allocation of more resources to mental health programmes, addressing barriers, enhancing mental health surveillance, and reduction of stigma.
