The duration of untreated psychosis (DUP) has been widely studied. However, for individuals with attenuated psychosis syndrome (APS), it is unclear whether the duration of untreated prodromal symptoms (DUPrS) also has a negative effect on the progression of psychosis. Our aim was to identify demographic and clinical factors contributing to the DUPrS in a large sample of individuals with APS, and to evaluate the association between DUPrS and the conversion to psychosis. A sample of 391 individuals with APS, who were identified through a structured interview for prodromal syndromes, were included in this study, of whom a total of 334 patients had completed at least a 1-year clinical follow-up. A total of 57 individuals had converted to psychosis. The average DUPrS was 4.8 months for the whole sample. Individuals with a longer DUPrS were likely to be men, non-local residents, with abnormal thought symptoms, a higher severity level of negative symptoms, the lower severity level of general symptoms, and lower level of general function before the onset of attenuated positive symptoms. A DUPrS of less than 2 months, or more than 6 months, lowered the risk for conversion to psychosis. Our data suggested that the association between the DUPrS and outcome in individuals with APS were likely to be different, which is either long or short DUPrS was not related to future psychosis onset. Individuals with APS were more likely to have a group of features associated with a longer DUPrS.

Our previous study has found that a long duration of untreated prodromal symptoms (DUPrS) does not increase the conversion risk to psychosis in individuals with attenuated psychosis syndrome (APS). However, whether a long DUPrS will lead to other poor outcomes remains unknown. The purpose of this study was to analyse the association between the DUPrS and outcomes (symptomatic and functional recovery) in APS population. A post hoc analysis was performed in 391 individuals with APS as identified by the structured interview. APS subjects had follow-up interviews every 6 months for 2 years following diagnosis. Poor functional outcome was defined as a Global Assessment of Functioning (GAF) score less than 60 at the time of follow-up. Poor symptomatic outcome was defined as at least one of the positive symptoms rated scores of 3 or higher. A post hoc analysis was performed in 391 individuals with APS as identified by the structured interview. APS subjects had follow-up interviews every 6 months for 2 years following diagnosis. Poor functional outcome was defined as a Global Assessment of Functioning (GAF) score less than 60 at the time of follow-up. Poor symptomatic outcome was defined as at least one of the positive symptoms rated scores of 3 or higher. Of total 391 individuals, 334 were followed up for 2 years to assess clinical outcome, 82 (24.6%) had shown conversion to psychosis, 79 (23.7%) met the criteria of poor functioning outcome, and 145 (43.4%) met the criteria of poor symptomatic outcome. A significant correlation between GAF scores and DUPrS was observed in the non-converter group, but not in the converters. Individuals with APS who had a longer DUPrS were correlated with poorer functional outcome. However, it was not correlated with poorer symptomatic outcome. While a longer DUPrS was not related to poor symptomatic outcome, it was significantly related to poor functional outcome. Our findings highlight the importance of reducing DUPrS to decrease future functional impairment in populations at risk for psychosis.

It has been shown that childhood trauma is associated with an increased risk of prodromal psychotic symptoms. However, research on the prevalence of prodromal psychotic symptoms among self-taught examination students and the relationship with childhood trauma remains limited. The aim of this study was to investigate the prevalence of prodromal psychotic symptoms among self-taught examination students, explore the impact of childhood trauma on prodromal psychotic symptoms, and its underlying mechanisms. From January 5 to 18, 2024, a cross-sectional study was conducted on 670 self-taught examination students in Nantong University through the online survey platform “Wenjuanxing” ( www.wjx.cn ). These individuals completed the general information questionnaire, The childhood trauma questionnaire-Short Form (CTQ-SF), The Prodromal Questionnaire-Brief (PQ-B), The Depression Anxiety Stress Scale (DASS-21). Data analysis was carried out using SPSS 25.0 and the PROCESS macro. (1) The prevalence of prodromal psychotic symptoms in self-taught examination students was 20.6% (138/670); (2) The total effect of childhood emotional abuse and prodromal psychotic symptoms in self-taught examination students was 2.9859. The mediating effect of anxiety (effect value: 1.4611), depression (effect value: 0.6201), social support (effect value: − 0.1214), and health conditions (effect value: 0.1954) in the relationship between childhood emotional abuse and prodromal psychotic symptoms of self-taught examination students, accounts for 72.18% of the total effect. Childhood trauma can not only independently predict the risk of prodromal psychotic symptoms among self-taught examination students, but also predict the risk of prodromal psychotic symptoms indirectly by affecting anxiety, depression, social support, and health conditions. Targeted measures should be taken to reduce the prodromal psychotic symptoms in this neglected group of self-taught examination students.

Childhood adversity is associated with psychopathology. First evidence in adults suggests that threat anticipation, i.e., an enhanced anticipation of unpleasant events creating an enduring sense of threat, may be a putative mechanism linking childhood adversity to psychopathology. This study aimed to test the indirect effect of childhood adversity on psychopathology via threat anticipation in a large community sample of adolescents. We measured childhood trauma and bullying victimization (as indicators of childhood adversity), threat anticipation, general psychopathology and prodromal psychotic symptoms in adolescents aged 12–16 years (full sample size N = 1682; minimum sample size in the complete case sample N = 449) in wave I of the SIGMA study. We found strong evidence that childhood adversity (e.g. childhood trauma, adj. β (aβ) = 0.54, p < .001) and threat anticipation (e.g. aβ = 0.36, p < .001) were associated with general psychopathology and prodromal psychotic symptoms. Moreover, there was evidence that the association between childhood adversity, general psychopathology and prodromal psychotic symptoms is mediated via pathways through threat anticipation (e.g. childhood trauma, aβindirect effect = 0.13, p < .001). Threat anticipation may be a potential mechanism linking childhood adversity and psychopathology in adolescents.

Background Implementing training programs to educate patients on the prodromal symptoms of acute coronary syndrome (ACS) may assist patients in accurately recognizing these symptoms, and ultimately decrease their time delay in seeking emergency medical services (EMS). However, the effectiveness of this approach remains uncertain, particularly among the Chinese population. Methods A cross-sectional study was conducted within 22 communities in Beijing, China between 2015 and 2018, with a total of 1099 participants recruited. The study utilized a standardized questionnaire to evaluate the presence of intentional decision delay in turning to EMS under a hypothetical chest pain, the participants’ knowledge of ACS prodromal symptoms, and whether they had ever received any training programs aimed at increasing their symptom knowledge. Mediation analysis was performed with regression models and bootstrapping methods, and gender difference was further analyzed through moderated mediation analysis. Results A total of 1099 participants (58.2% female, median [IQR] age 34 [20]) were included in the study. The results of the mediation analysis indicated that training programs were associated with a decrease risk in decision delay, with increased knowledge playing a mediating role (mediation effect/total effect = 36.59%, P  < 0.0001). Gender modified this mediation effect, with it being observed only in the male group. Specifically, training programs were not found to significantly decrease decision delay among females ( P  > 0.05), even though they did improve women’s knowledge of ACS prodromal symptoms (β = 0.57, P  = 0.012). Conclusion The results suggested a relationship between prior training programs and reduced decision delay, with increased knowledge of prodromal symptoms of ACS serving as a mediator. However, the effect was only observed in male participants and not in female participants. This highlights the notion that mere transfer of knowledge regarding ACS prodromal symptoms may not be sufficient to mitigate decision delay in the female population. Further research is needed to corroborate these results and to gain deeper insights into the gender-specific barriers encountered in this study.

Aim To synthezise quantitative current evidence on the prodromal symptoms experienced by women before the onset of acute coronary syndrome (ACS), focusing on the prevalence, nature and clinical implications of these symptoms. Design A systematic review. Methods The review adhered to Synthesis without meta‐analysis guidelines and was registered with the PROSPERO database (ID: CRD42024541840). Systematic searches were conducted in PubMed, CINAHL, APA PsycArticles, APA PsycInfo and EMBASE. Included studies were quantitative, focused on women aged ≥ 18 years with confirmed acute coronary syndrome and reported prodromal symptoms. The Quality Assessment with Diverse Studies and the Cochrane Risk of Bias in non‐randomized studies of Interventions tools were used for critical appraisal. Results Of 2170 identified records, 11 full‐text studies were reviewed. The most frequently reported prodromal symptom was unusual fatigue, followed by sleep disturbances and anxiety. Prodromal symptoms often occurred well before the acute event but were frequently misattributed to non‐cardiac causes. Chest pain, typically associated with acute coronary syndrome, was less commonly reported as a prodromal symptom in women, complicating timely diagnosis and treatment. Conclusions The results highlight the need for increased awareness of these early warning signs among healthcare providers and women themselves. Enhanced recognition and understanding of these symptoms could lead to more timely and accurate diagnosis, ultimately improving outcomes for women at risk of acute myocardial infarction. Implications for the Profession and/or Patient Care To educate both health professionals and patients about the variability and significance of prodromal symptoms in women is essential to improve outcomes. Impact This study is the first to systematically review and synthesize the existing literature on prodromal symptoms of acute coronary syndrome specifically in women. The results show l that women are more likely to experience a broader and more complex range of prodromal symptoms, including fatigue, sleep disturbances and anticipatory anxiety, which often precede the acute event. The insights provided by our review could lead to significant improvements in the early diagnosis and treatment of AMI in women, ultimately reducing morbidity and mortality rates associated with cardiovascular diseases. Reporting Method The review has adhered to relevant EQUATOR guidelines and has followed Synthesis without meta‐analysis guidelines. Patient or Public Contribution No patient or public contribution.

A personality trait that often elicits poor and uneasy interpersonal relationships is interpersonal sensitivity. The aim of the present study was to explore the relationship between interpersonal sensitivity and psychosocial functioning in individuals at ultra-high risk for psychosis as compared to help-seeking individuals who screened negative for an ultra-high risk of psychosis. A total sample of 147 adolescents and young adult who were help seeking for emerging mental health problems participated in the study. The sample was divided into two groups: 39 individuals who met criteria for an ultra-high-risk mental state (UHR), and 108 (NS). The whole sample completed the Interpersonal Sensitivity Measure (IPSM) and the Global Functioning: Social and Role Scale (GF:SS; GF:RS). Mediation analysis was used to explore whether attenuated negative symptoms mediated the relationship between interpersonal sensitivity and social functioning. Individuals with UHR state showed higher IPSM scores and lower GF:SS and GF:RS scores than NS participants. A statistically negative significant correlation between two IPSM subscales (Interpersonal Awareness and Timidity) and GF:SS was found in both groups. Our results also suggest that the relationship between the aforementioned aspects of interpersonal sensitivity and social functioning was not mediated by negative prodromal symptoms. This study suggests that some aspects of interpersonal sensitivity were associated with low level of social functioning. Assessing and treating interpersonal sensitivity may be a promising therapeutic target to improve social functioning in young help-seeking individuals.

Interpersonal sensitivity is a personality trait described as excessive awareness of both the behaviour and feelings of others. Although interpersonal sensitivity has been found to be one of the vulnerability factors to depression, there has been little interest in its relationship with the prodromal phase of psychosis. The aims of this study were to examine the level of interpersonal sensitivity in a sample of individuals with an at-risk mental state (ARMS) for psychosis and its relationship with other psychopathological features. Sixty-two individuals with an ARMS for psychosis and 39 control participants completed a series of self-report questionnaires, including the Interpersonal Sensitivity Measure (IPSM), the Prodromal Questionnaire (PQ), the Ways of Coping Questionnaire (WCQ) and the Depression and Anxiety Stress Scale (DASS). Individuals with an ARMS reported higher interpersonal sensitivity compared to controls. Associations between interpersonal sensitivity, positive psychotic symptoms (i.e. paranoid ideation), avoidant coping and symptoms of depression, anxiety and stress were also found. This study suggests that being 'hypersensitive' to interpersonal interactions is a psychological feature of the putatively prodromal phase of psychosis. The relationship between interpersonal sensitivity, attenuated positive psychotic symptoms, avoidant coping and negative emotional states may contribute to long-term deficits in social functioning. We illustrate the importance, when assessing a young client with a possible ARMS, of examining more subtle and subjective symptoms in addition to attenuated positive symptoms.

Background Prodromal cardiac symptoms are warning signals preceding cardiac disease. Previous studies have shown some gender differences in prodromal symptoms as well as established risk factors for MI. This study aims to map possible gender differences in social factors and established risk factors preceding myocardial infarction (MI). Methods The study includes data of N = 213 middle-aged men and women, all diagnosed with myocardial infarction (ICD-10 I21.9) from the region of south-east Sweden. They answered a questionnaire at discharge from the cardiologic clinic and additional clinical data from medical records were merged from the National Swedeheart Register. Results The dominant prodromal symptom for both sexes were experience of chest pain at the onset of MI. The major gender differences were that significantly more females ( p  = 0.015) had a hyperlipidemia diagnose. Females also reported to have experienced higher stress load the year preceding myocardial infarction with serious life events ( p  = 0.019), strained economy ( p  = 0.003), and reports of sadness/depression ( p  < 0.001). Females reported higher perceived stress load than men ( p  = 0.006). Men had higher systolic blood pressure than women at hospital admission and a higher systolic- and diastolic blood pressure at discharge. Conclusions Influences of the social environment, such as serious life events, strained economy, depression, stress, and sleep deprivation were stronger as potential risk factors for myocardial infarction in women than among men. Of the traditional risk factors only, hyperlipidemia was more frequent among women. These findings could contribute to a deeper understanding of diagnostic differences between gender, as well as a more gender-oriented cardiovascular preventive work.

Abstract Video-polysomnography (v-PSG) is essential for diagnosing rapid eye movement (REM) sleep behavior disorder (RBD). Although there are current American Academy of Sleep Medicine standards to diagnose RBD, several aspects need to be addressed to achieve harmonization across sleep centers. Prodromal RBD is a stage in which symptoms and signs of evolving RBD are present, but do not yet meet established diagnostic criteria for RBD. However, the boundary between prodromal and definite RBD is still unclear. As a common effort of the Neurophysiology Working Group of the International RBD Study Group, this manuscript addresses the need for comprehensive and unambiguous v-PSG recommendations to diagnose RBD and identify prodromal RBD. These include: (1) standardized v-PSG technical settings; (2) specific considerations for REM sleep scoring; (3) harmonized methods for scoring REM sleep without atonia; (4) consistent methods to analyze video and audio recorded during v-PSGs and to classify movements and vocalizations; (5) clear v-PSG guidelines to diagnose RBD and identify prodromal RBD. Each section follows a common template: The current recommendations and methods are presented, their limitations are outlined, and new recommendations are described. Finally, future directions are presented. These v-PSG recommendations are intended for both practicing clinicians and researchers. Classification and quantification of motor events, RBD episodes, and vocalizations are however intended for research purposes only. These v-PSG guidelines will allow collection of homogeneous data, providing objective v-PSG measures and making future harmonized multicentric studies and clinical trials possible.
