RESUMO

PURPOSE: To explore gender differences of the associations between childhood adversity (CA) subtypes and psychiatric symptoms in the general population. METHODS: Data of 791 participants were retrieved from a general population twin cohort. The Symptom Checklist-90 Revised (SCL-90) and the Childhood Trauma Questionnaire were used to assess overall psychopathology with nine symptom domains scores and total CA with exposure to five CA subtypes, respectively. The associations between CA and psychopathology were analyzed in men and women separately and were subsequently compared. RESULTS: Total CA was associated with total SCL-90 and all symptom domains without significant gender differences. However, the analyses of CA subtypes showed that the association between emotional abuse and total SCL-90 was stronger in women compared to men [χ2(1) = 4.10, P = 0.043]. Sexual abuse was significantly associated with total SCL-90 in women, but emotional neglect and physical neglect were associated with total SCL-90 in men. Exploratory analyses of CA subtypes and SCL-90 subdomains confirmed the pattern of gender-specific associations. In women, emotional abuse was associated with all symptom domains, and sexual abuse was associated with all except phobic anxiety and interpersonal sensitivity. In men, emotional neglect was associated with depression, and physical neglect was associated with phobic anxiety, anxiety, interpersonal sensitivity, obsessive-compulsive, paranoid ideation, and hostility subdomains. CONCLUSION: CA is a trans-syndromal risk factor regardless of gender. However, differential associations between CA subtypes and symptom manifestation might exist. Abuse might be particularly associated with psychopathology in women, whereas neglect might be associated with psychopathology in men.

RESUMO

Introduction: Intentional self-harm in adolescents and young people, including both suicidal behaviors and non-suicidal self-injury (NSSI), is a serious issue in mental health systems. However, the majority of studies on self-harm in adolescents and young people focused on a quantitative methodology which might have limitations in explaining this complex phenomenon of intentional self-harm. Therefore, this study aimed to describe the subjective experiences of adolescents and young people who presented with intentional self-harm in order to provide a better understanding of this behavioral phenomenon. Methods: This is an exploratory qualitative study that uses phenomenological processes and thematic analysis. Twenty subjects aged 13-29 years were included in this study. Results: The results revealed six themes regarding predisposing child-rearing environments and nine themes regarding factors related to the cessation of intentional self-harm. Moreover, it demonstrated the important functions of self-harm as an intrapersonal strategy for emotional regulation. Discussion: In conclusion, this study underscored the importance of understanding the developmental and cessation pathways of these complex behaviors.

RESUMO

BACKGROUND: People with schizophrenia spectrum disorders (SSD) frequently present cognitive impairments. Here, we investigated whether the exposome score for schizophrenia (ES-SCZ) - a cumulative environmental exposure score - was associated with impairments of neurocognition, social cognition, and perception in patients with SSD, their unaffected siblings, and healthy controls. METHODS: This cross-sectional sample consisted of 1200 patients, 1371 siblings, and 1564 healthy controls. Neurocognition, social cognition, and perception were assesed using a short version of the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), the Degraded Facial Affect Recognition Task (DFAR), and the Benton Facial Recognition Test (BFR), respectively. Regression models were used to analyze the association between ES-SCZ and cognitive domains in each group. RESULTS: There were no statistically significant associations between ES-SCZ and cognitive domains in SSD. ES-SCZ was negatively associated with T-score of cognition in siblings (B=-0.40, 95% CI -0.76 to -0.03) and healthy controls (B=-0.63, 95% CI -1.06 to -0.21). Additionally, ES-SCZ was positively associated with DFAR-total in siblings (B=0.83, 95% CI 0.26 to 1.40). Sensitivity analyses excluding cannabis use history from ES-SCZ largely confirmed the main findings. CONCLUSIONS: Longitudinal cohorts may elucidate how environmental exposures influence the onset and course of cognitive impairments in trans-syndromic psychosis spectrum.

RESUMO

PURPOSE: This 2-year, multi-center, prospective, observational study aimed to describe the course and examine baseline characteristics for predicting disability in Thai patients with schizophrenia. METHODS: Participants were patients with schizophrenia aged 18-65 years receiving treatment in five tertiary hospitals. Disability was defined by a score of 10 or more of the 12-item World Health Organization Disability Assessment Schedule, version 2.0 (12-item WHODAS 2.0). Other data being collected included socio-demographic data, course of illness, antipsychotics, antipsychotic drug attitudes, behavioral/psychiatric symptoms, alcohol use, social supports, and quality of life at five visits, including weeks 0 (baseline), 24, 48, 72, and 96. RESULTS: Of the 158 enrolled patients, we analyzed the data of 119 participants who were reassessed at least once during the follow-up. These 119 participants (70% male) had median age and age at psychotic onset of 38 and 22 years, respectively. Disability was found in 43 (36.1%) participants at baseline and 72 (64.7%) participants at week 96. The median [interquartile ranges] WHODAS scores at five time points were 6 [3-12], 9 [4-13], 10 [6-10], 10 [4-10], and 10 [6-10], respectively (p < 0.001). The multivariate logistic regression analysis revealed that duration of psychosis (adjusted odds ratio = 1.08, 95%CI = 1.04 - 1.14, p = 0.001) and depression (adjusted odds ratio = 3.54, 95%CI = 1.14 - 11.06, p = 0.029) at baseline predicted 2-year disability. CONCLUSIONS: Thai patients with schizophrenia had an increase in disability over a 2-year follow-up period. Duration of psychosis and depression were predictors of disability in these patients.

RESUMO

Background: The effects of the COVID-19 pandemic on family well-being and functioning were generally a concern for healthcare providers in many countries. Objectives: To explore the changes in family functioning and family happiness during the pandemic in Thailand and to investigate factors associated with the changes in family happiness. Methods: This was a cross-sectional study conducted between November and December 2021. Online questionnaires regarding family functioning, family happiness, domestic violence, and COVID-19-related experiences were used. Results: A total of 485 participants were included in this study. The perceived family happiness slightly decreased from 8.19 (pre-pandemic score) to 7.62 (post-pandemic score). In contrast, the general family functioning (SCORE-15 index), strength, and communication subscale scores after the onset of the COVID-19 pandemic were significantly lower than those of the pre-pandemic period. Moreover, the prevalence of verbal and physical violence significantly reduced during the pandemic. In addition, the change in family functioning was the strongest factor associated with the change in family happiness. Conclusion: In general, family functioning slightly improved; however, perceived family happiness decreased during the pandemic. In addition, the change in family functioning was the strongest factor associated with the change in family happiness.

RESUMO

BACKGROUND: Many studies have shown that the prevalence of psychiatric disorders in patients with epilepsy (PWE) appears higher than that in general population. However, most epidemiological studies regarding psychiatric comorbidities among PWE were conducted in Western countries. This work aimed to determine the prevalence of psychiatric disorders in Thai PWE, including potential variables that could be associated with psychiatric disorders. METHODS: A cross-sectional study was conducted at Ramathibodi Hospital. A total of 170 patients (aged 18 years or older) diagnosed as having epilepsy by a neurologist were recruited at the outpatient neurology clinic. Demographic and clinical characteristics were collected. Participants were evaluated for any psychiatric disorders according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, using a structured diagnostic interview. The prevalence of psychiatric disorders was determined. The associations between potential variables and the presence of psychiatric disorders in PWE were analyzed using chi-square or Fisher's exact tests, t-test, and logistic regression. RESULTS: Among 170 patients, 43 (25.3%) fulfilled diagnostic criteria for one or more psychiatric disorders. The prevalence of depressive disorders was shown to be highest at 17.1%, followed by psychotic disorders (8.2%), bipolar disorder (7.1%), anxiety disorders (5.3%), and obsessive-compulsive disorder (OCD) (2.9%). Electroencephalogram (EEG) abnormalities in the temporal lobe was found to be a significant predictor of having psychiatric disorders in PWE (adjusted odds ratio (OR): 4.01, 95% confidence interval (CI): 1.47-10.92, P-value = 0.007). CONCLUSIONS: The prevalence of psychiatric disorders among Thai PWE was higher than that in general population. Screening for psychiatric disorders in PWE is recommended, especially among those who have EEG abnormalities in the temporal lobe.

RESUMO

BACKGROUND: The English version of the 4 'A's Test (4AT) is a rapid screening tool for delirium with a high sensitivity and specificity among hospitalized elderly patients. OBJECTIVE: To develop the Thai version of the 4AT (4AT-T) and assess its validity. SUBJECTS AND SETTING: A total of 97 elderly patients aged 60 years or above who were admitted to the general medical wards were included. METHODS: Both authors independently translated the English version of the 4AT into Thai and thereafter developed a single reconciled forward translation by consensus. Back translation was performed by a bilingual native English speaker and it was then reviewed to ensure its agreement with the original one. After 24 hours of admission, subjects were enrolled and clinical data collected. Definite diagnosis of delirium was made by a psychiatrist using the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text-Revision criteria and the 6-item Thai Delirium Rating Scale; the 4AT was then administered to participants by nurses within 30 minutes. A 4AT score ≥4 was considered positive for delirium screening. The optimal cut-off point of the 4AT-T was identified by Youden's index. RESULTS: In all, 24 out of 97 participants met the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text-Revision criteria for delirium. At a cut-off score of 4 or greater, the 4AT-T exhibited satisfactory diagnostic performance with a sensitivity of 83.3% (95% confidence interval (CI): 62.6%-95.3%) and specificity of 86.3% (95% CI: 76.3%-93.2%). The area under the receiver operating characteristic curve was 0.92. The specified score provided maximal Youden's index, suggesting an optimal criterion value for delirium screening. CONCLUSION: The 4AT-T is a valid delirium-screening instrument for hospitalized elderly patients with acute medical illnesses.

RESUMO

BACKGROUND: Our earlier genome-wide expression study revealed up-regulation of a tryptophan-catabolizing enzyme, indoleamine 2,3-dioxygenase (IDO1), in patients with scrub typhus. This gene has been previously reported to have anti-microbial activity in a variety of infectious diseases; therefore, we aimed to prove whether it is also involved in host defense against Orientia tsutsugamushi (OT) infection. METHODOLOGY/PRINCIPAL FINDINGS: Using LC-MS, we observed an increased ratio of serum L-kynurenine to serum L-tryptophan in patients with scrub typhus, which suggests an active catalytic function of this enzyme upon the illness. To evaluate the effect of IDO1 activation on OT infection, a human macrophage-like cell line THP-1 was used as a study model. Although transcription of IDO1 was induced by OT infection, its functional activity was not significantly enhanced unless the cells were pretreated with IFN-γ, a potent inducer of IDO1. When the degree of infection was evaluated by quantitative real-time PCR, the relative number of OT 47 kDa gene per host genes, or infection index, was markedly reduced by IFN-γ treatment as compared to the untreated cultures at five days post-infection. Inhibition of IDO1 activity in IFN-γ treated cultures by 1-methyl-L-tryptophan, a competitive inhibitor of IDO1, resulted in partial restoration of infection index; while excessive supplementation of L-tryptophan in IFN-γ treated cultures raised the index to an even higher level than that of the untreated ones. Altogether, these data implied that IDO1 was partly involved in restriction of OT growth caused by IFN-γ through deprivation of tryptophan. CONCLUSIONS/SIGNIFICANCE: Activation of IDO1 appeared to be a defensive mechanism downstream of IFN-γ that limited intracellular expansion of OT via tryptophan depletion. Our work provided not only the first link of in vivo activation of IDO1 and IFN-γ-mediated protection against OT infection but also highlighted the promise of this multifaceted gene in scrub typhus research.

RESUMO

Orientia tsutsugamushi is the causal agent of scrub typhus, a public health problem in the Asia-Pacific region and a life-threatening disease. O. tsutsugamushi is an obligate intracellular bacterium that mainly infects endothelial cells. We demonstrated here that O. tsutsugamushi also replicated in monocytes isolated from healthy donors. In addition, O. tsutsugamushi altered the expression of more than 4,500 genes, as demonstrated by microarray analysis. The expression of type I interferon, interferon-stimulated genes and genes associated with the M1 polarization of macrophages was significantly upregulated. O. tsutsugamushi also induced the expression of apoptosis-related genes and promoted cell death in a small percentage of monocytes. Live organisms were indispensable to the type I interferon response and apoptosis and enhanced the expression of M1-associated cytokines. These data were related to the transcriptional changes detected in mononuclear cells isolated from patients with scrub typhus. Here, the microarray analyses revealed the upregulation of 613 genes, which included interferon-related genes, and some features of M1 polarization were observed in these patients, similar to what was observed in O. tsutsugamushi-stimulated monocytes in vitro. This is the first report demonstrating that monocytes are clearly polarized in vitro and ex vivo following exposure to O. tsutsugamushi. These results would improve our understanding of the pathogenesis of scrub typhus, during which interferon-mediated activation of monocytes and their subsequent polarization into an M1 phenotype appear critical. This study may give us a clue of new tools for the diagnosis of patients with scrub typhus.
