The course of post-traumatic stress disorder (PTSD) is complex and remains an area of active investigation, as analyses aimed at identifying predictors of PTSD outcomes often produce variable and inconsistent results. This particular study delves into the progression and patterns of PTSD over a two-year period, focusing on individuals who are in the recovery phase from severe physical injuries. The research aims to understand the different trajectories that PTSD can take and to identify the factors that may influence these pathways, with the goal of enhancing our understanding and treatment of this challenging and multifaceted condition.

Patients were recruited from a trauma center at a university hospital in South Korea between June 2015 and January 2021. At baseline, 1142 patients underwent evaluations encompassing trauma and PTSD-related measures, socio-demographic characteristics, pre-trauma characteristics, and peri-trauma assessments. They were subsequently followed up for PTSD using the Clinician-administered PTSD Scale (CAPS) at 3, 6, 12, and 24 months. The analyzed sample consisted of 1014 patients who were followed up at least once after the baseline and 3-month evaluations. Latent class growth analysis was employed to identify distinct trajectory groups, and logistic regression models to ascertain predictors associated with each trajectory.

The study identified five unique trajectories of PTSD progression among the patients: resilient, worsening/recovery, worsening, recovery, and chronic groups. The "worsening/recovery” trajectory, which indicates patients whose symptoms initially worsened but later improved, was predominantly associated with individuals who had experienced previous traumatic events and those who had sustained injuries from traffic accidents. On the other hand, the "worsening” trajectory, where patients' symptoms continuously deteriorated over time, was linked to individuals with higher education levels and elevated depressive symptoms. The "recovery” trajectory, characterized by a gradual improvement in symptoms, was more common in female patients and those with a history of childhood abuse, traffic-related injuries, a dissociative subtype of PTSD, and higher levels of anxiety and depressive symptoms. Lastly, the "chronic” trajectory, where patients experienced persistently severe symptoms, was predicted by the presence of a dissociative subtype of PTSD and heightened anxiety symptoms. These findings illustrate the diverse paths PTSD can take and highlight the importance of various factors in influencing these trajectories.

These findings highlighted the heterogeneity of PTSD symptom development and thus the importance of considering individual characteristics when assessing and addressing PTSD following severe physical injuries.

This study examined the relationship between changes in physical activity and their impact on exercise capacity and health-related quality of life over a 3-year span in patients with CHD.

We evaluated 99 young patients with CHD, aged 13–18 years at the outset. Physical activity, health-related quality of life, and exercise capacity were assessed via questionnaires and peak oxygen uptake measurements at baseline and after 3 years; changes in measures were estimated between the two time points and categorised into quartiles. Participants were stratified according to achieved (active) or not-achieved (inactive) recommended levels of physical activity (≥150 minutes/week) at both time points.

Despite increases in physical activity, exercise capacity, and health-related quality of life over 3 years, the changes were not statistically significant (all p > 0.05). However, a positive association was found between physical activity changes and exercise capacity (ß = 0.250, p = 0.040) and health-related quality of life improvements (ß = 0.380, p < 0.001). Those with the most pronounced physical activity increase showed notable exercise capacity (p < 0.001) and health-related quality of life increases (p < 0.001) compared with patients with the largest decline in physical activity. The active-inactive category demonstrated a notable decline in exercise capacity compared to the active-active group, while the inactive-active group showed health-related quality of life improvements.

Over 3 years, increased physical activity was consistently linked to increases in exercise capacity and health-related quality of life in patients with CHD, highlighting the potential of physical activity augmentation as an intervention strategy.

Predictive values of multiple serum biomarkers for suicidal behaviours (SBs) have rarely been tested. This study sought to evaluate and develop a panel of multiple serum biomarkers for predicting SBs in outpatients receiving a 12-month pharmacotherapy programme for depressive disorders.

At baseline, 14 serum biomarkers and socio-demographic/clinical characteristics including previous suicidal attempt and present suicidal severity were evaluated in 1094 patients with depressive disorders without a bipolar diagnosis. Of these, 884 were followed for increased suicidal severity and fatal/non-fatal suicide attempt outcomes over a 12-month treatment period. Individual and combined effects of serum biomarkers on these two prospective SBs were estimated using logistic regression analysis after adjustment for relevant covariates.

Increased suicidal severity and fatal/non-fatal suicide attempt during the 12-month pharmacotherapy were present in 155 (17.5%) and 38 (4.3%) participants, respectively. Combined cortisol, total cholesterol, and folate serum biomarkers predicted fatal/non-fatal suicide attempt, and these with interleukin-1 beta and homocysteine additionally predicted increased suicidal severity, with clear gradients robust to adjustment (p values < 0.001).

Application of multiple serum biomarkers could considerably improve the predictability of SBs during the outpatient treatment of depressive disorders, potentially highlighting the need for more frequent monitoring and risk appraisal.

The role of childhood abuse and serum brain-derived neurotrophic factor (BDNF) levels in suicidal behaviour is controversial.

We aimed to investigate the individual and interactive effects of the childhood abuse and serum BDNF on suicidal behaviour before and after pharmacologic treatment in patients with depressive disorders.

At baseline, reported childhood emotional, physical and sexual abuse were ascertained and serum BDNF levels were measured in 1094 patients with depressive disorder, 884 of whom were followed during a 1-year period of stepwise pharmacotherapy. Suicidal behaviours evaluated at baseline were previous suicide attempt and baseline suicide severity, and suicidal behaviours evaluated at follow-up were increased suicide severity and fatal/non-fatal suicide attempt. Individual and interactive associations of any childhood abuse and serum BDNF levels with four types of suicidal behaviours were analysed using logistic regression models, after adjusting relevant covariates.

Individual associations of childhood abuse were significant only with previous suicide attempt, and no significant individual associations were found for serum BDNF with any suicide outcome. However, the presence of both childhood abuse and lower serum BDNF levels was associated with the highest prevalence/incidence of all four suicidal behaviours, with significant interactions for baseline suicide severity and fatal/non-fatal suicide attempt during follow-up.

Synergistic interactive effects of child abuse and serum BDNF levels on suicidal behaviours were found before and after pharmacologic treatment in patients with depressive disorders. Information combining childhood abuse and serum BDNF levels could improve predictions of suicidal behaviour in patients with depressive disorders.

Social anxiety disorder (SAD) is characterized by anxiety regarding social situations, avoidance of external social stimuli, and negative self-beliefs. Virtual reality self-training (VRS) at home may be a good interim modality for reducing social fears before formal treatment. This study aimed to find neurobiological evidence for the therapeutic effect of VRS.

Fifty-two patients with SAD were randomly assigned to a VRS or waiting list (WL) group. The VRS group received an eight-session VRS program for 2 weeks, whereas the WL group received no intervention. Clinical assessments and functional magnetic resonance imaging scanning with the distress and speech evaluation tasks were repeatedly performed at baseline and after 3 weeks.

The post-VRS assessment showed significantly decreased anxiety and avoidance scores, distress index, and negative evaluation index for ‘self’, but no change in the negative evaluation index for ‘other’. Patients showed significant responses to the distress task in various regions, including both sides of the prefrontal regions, occipital regions, insula, and thalamus, and to the speech evaluation task in the bilateral anterior cingulate cortex. Among these, significant neuronal changes after VRS were observed only in the right lingual gyrus and left thalamus.

VRS-induced improvements in the ability to pay attention to social stimuli without avoidance and even positively modulate emotional cues are based on functional changes in the visual cortices and thalamus. Based on these short-term neuronal changes, VRS can be a first intervention option for individuals with SAD who avoid society or are reluctant to receive formal treatment.

To investigate the impacts of depression screening, diagnosis and treatment on major adverse cardiac events (MACEs) in acute coronary syndrome (ACS).

Prospective cohort study including a nested 24-week randomised clinical trial for treating depression was performed with 5–12 years after the index ACS. A total of 1152 patients recently hospitalised with ACS were recruited from 2006 to 2012, and were divided by depression screening and diagnosis at baseline and 24-week treatment allocation into five groups: 651 screening negative (N), 55 screening positive but no depressive disorder (S), 149 depressive disorder randomised to escitalopram (E), 151 depressive disorder randomised to placebo (P) and 146 depressive disorder receiving medical treatment only (M).

Cumulative MACE incidences over a median 8.4-year follow-up period were 29.6% in N, 43.6% in S, 40.9% in E, 53.6% in P and 59.6% in M. Compared to N, screening positive was associated with higher incidence of MACE [adjusted hazards ratio 2.15 (95% confidence interval 1.63–2.83)]. No differences were found between screening positive with and without a formal depressive disorder diagnosis. Of those screening positive, E was associated with a lower incidence of MACE than P and M. M had the worst outcomes even compared to P, despite significantly milder depressive symptoms at baseline.

Routine depression screening in patients with recent ACS and subsequent appropriate treatment of depression could improve long-term cardiac outcomes.

This research investigated patients who underwent surgery for a dilated aorta associated with a connective tissue disease or inflammatory vasculitis in children and adolescents.

The medical records of 11 patients who underwent aortic surgery for dilatation resulting from a connective tissue disease or inflammatory vasculitis between 2000 and 2017 were retrospectively reviewed.

The median age and body weight of the patients were 9.6 years (range 5.4 months–15.5 years) and 25.8 kg (range 6.8–81.5), respectively. The associated diseases were Marfan syndrome (n = 3), Loeys-Dietz syndrome (n = 3), Kawasaki disease (n = 1), Takayasu arteritis (n = 1), PHACE syndrome (n = 1), tuberous sclerosis (n = 1), and unknown (n = 1). The most common initially affected area was the ascending aorta. During the 66.4 ± 35.9 months of follow-up, two Marfan syndrome patients died, and four patients (one Marfan syndrome and three Loeys-Dietz syndrome) had repeated aortic operation. Except for one patient, the functional class was well maintained in all patients who were followed up.

Cases of surgical treatment for a dilated aorta associated with a connective tissue disease and inflammatory vasculitis are rare in children and adolescents at our institution. Most of the patients in this study showed a tolerable postoperative course. However, the aorta showed progressive dilation over time even after surgical treatment, especially in patients with Loeys-Dietz syndrome. In these patients, close and more frequent regular follow-up is required.

This study aimed to investigate associations among spirituality, coping strategies, quality of life (QOL), and the effects of depression and anxiety thereon in cancer patients.

In total, 237 cancer patients referred to a psycho-oncology clinic at a university hospital in Korea were enrolled. After identifying predictors of patient QOL in a stepwise regression model, we developed a hypothetical path model wherein interpersonal coping was considered as a mediating variable between spirituality (meaning/peace) and QOL and wherein depression and anxiety affected each of these three variables.

The direct effect of spirituality (meaning/peace) on QOL was 36.7%. In an indirect model, interpersonal coping significantly mediated the relationship between spirituality (meaning/peace) and QOL. Depression exerted the largest negative effect on spirituality (meaning/peace), interpersonal coping, and QOL. Anxiety had negative effects on spirituality (meaning/peace) and QOL, but a positive effect on interpersonal coping.

Interpersonal coping strategies work as a partial mediator of the relationship between meaning/peace subscales of spirituality and QOL. Effective management of depression may help in achieving better outcomes associated therewith. Greater attention and efforts to improve social connectedness and meaning of life in spiritual well-being may improve the QOL of cancer patients.
