Classification and analysis of text transcription from Thai depression assessment tasks among patients with depression.

Depression is a serious mental health disorder that poses a major public health concern in Thailand and have a profound impact on individuals' physical and mental health. In addition, the lack of number to mental health services and limited number of psychiatrists in Thailand make depression particularly challenging to diagnose and treat, leaving many individuals with the condition untreated. Recent studies have explored the use of natural language processing to enable access to the classification of depression, particularly with a trend toward transfer learning from pre-trained language model. In this study, we attempted to evaluate the effectiveness of using XLM-RoBERTa, a pre-trained multi-lingual language model supporting the Thai language, for the classification of depression from a limited set of text transcripts from speech responses. Twelve Thai depression assessment questions were developed to collect text transcripts of speech responses to be used with XLM-RoBERTa in transfer learning. The results of transfer learning with text transcription from speech responses of 80 participants (40 with depression and 40 normal control) showed that when only one question (Q1) of "How are you these days?" was used, the recall, precision, specificity, and accuracy were 82.5%, 84.65, 85.00, and 83.75%, respectively. When utilizing the first three questions from Thai depression assessment tasks (Q1 - Q3), the values increased to 87.50%, 92.11%, 92.50%, and 90.00%, respectively. The local interpretable model explanations were analyzed to determine which words contributed the most to the model's word cloud visualization. Our findings were consistent with previously published literature and provide similar explanation for clinical settings. It was discovered that the classification model for individuals with depression relied heavily on negative terms such as 'not,' 'sad,', 'mood', 'suicide', 'bad', and 'bore' whereas normal control participants used neutral to positive terms such as 'recently,' 'fine,', 'normally', 'work', and 'working'. The findings of the study suggest that screening for depression can be facilitated by eliciting just three questions from patients with depression, making the process more accessible and less time-consuming while reducing the already huge burden on healthcare workers.

Effectiveness of a community health worker-led case management programme to improve outcomes for people with psychotic disorders in Thailand: a one-year prospective cohort study.

BACKGROUND: Intensive case management (ICM) programmes for psychotic patients are effective in improving outcomes, but often unfeasible in resource-poor settings, as they typically require extensive human resources and expertise. We developed and evaluated the effectiveness of a less intensive case management program (LICM), led by community health workers, on one-year social functioning and service use. METHODS: A prospective cohort study was conducted on patients aged 18 and above residing in a hospital catchment area. Outcomes were compared between LICM (n = 64) and non-LICM participants (n = 485). A counterfactual framework approach was applied to assess causal effects of the LICM on outcomes. The programme effectiveness was analyzed by augmented-inverse probability of treatment weighting (AIPW) to estimate potential outcome mean (POM) and average treatment effect (ATE). Outcomes were employment status and use of emergency, inpatient and outpatient services. Analyses were stratified by the number of previous psychotic relapse (≤ 1, > 1) to assess heterogeneity of treatment effect on those in an early and later stages of psychotic illness. RESULTS: In the early-stage cohort, the likelihood of being employed at one year post-baseline was significantly greater in LICM participants than non-LICM participants (ATE 0.10, 95%CI 0.05-0.14, p < 0.001), whereas service use of all types, except outpatient, was not significantly different between the two groups. In the later-stage cohort, the likelihoods of employment between the two groups at post-baseline were similar (ATE -0.02, 95%CI -0.19-0.15, p = 0.826), whereas service use of all types was significantly higher in LICM participants. CONCLUSION: LICM in a setting where community mental services are scarce may benefit those at an early stage of psychotic illness, by leading to better social functioning and no higher use of unscheduled services at the end of the programme, possibly through their better prognosis and medication adherence. A more intensive case management model may be appropriate for those in a later stage of the illness.

Etiology of Dementia in Thai Patients.

INTRODUCTION: Molecular imaging has been developed and validated in Thai patients, comprising a portion of patients in the dementia registry. This should provide a more accurate diagnosis of the etiology of dementia, which was the focus of this study. METHODS: This was a multicenter dementia study. The baseline characteristics, main presenting symptoms, and results of investigations and cognitive tests of the patients were electronically collected in the registry. Functional imaging and/or molecular imaging were performed in patients with an equivocal diagnosis of the causes of dementia, especially in atypical dementia or young onset dementia (YOD). RESULTS: There were 454 patients in the study. The mean age of the patients was 78 years, with 60% female. Functional imaging and/or molecular imaging were performed in 57 patients (57/454 patients, 13%). The most common cause of dementia was Alzheimer's disease (AD; 50%), followed by vascular dementia (VAD; 24%), dementia with Lewy bodies (6%), Parkinson's disease dementia (6%), frontotemporal dementia (FTD; 2.6%), progressive supranuclear palsy (2%), multiple system atrophy (0.8%), and corticobasal syndrome (0.4%). YOD accounted for 17% (77/454 patients), with a mean age of 58 years. The causes of YOD were early onset amnestic AD (44%), VAD (16%), behavioral variant FTD (8%), posterior cortical atrophy (6.5%), and logopenic variant primary progressive aphasia (5.2%). CONCLUSION: AD was the most common cause of dementia in Thai patients and the distribution of other types of dementia and main presenting symptoms were similar to previous reports in Western patients; however, the proportion of YOD was higher.

Comparative Study in Quality of Life between Thai Endometrial Cancer Survivors and Healthy Women in Thammasat University Hospital.

BACKGROUND: This study aimed to survey quality of life (QoL) in endometrial cancer survivors between surgery with adjuvant therapy (radiation with or without chemotherapy) and surgery alone in Thammasat University Hospital, Thailand. MATERIALS AND METHODS: This cross-sectional study was conducted at the Gynecologic Oncology clinic, Thammasat University hospital, Thailand between March 2011 and May 2019. Participants were endometrial cancer cases who underwent surgical staging with or without adjuvant treatment (study) and healthy women who came to gynecologic department for annual cervical screening (control). Assessment of QoL was investigated via the structural questionnaire designed by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 (Thai version). RESULTS: During the period of the study, 94 participants who were diagnosed with endometrial cancer and underwent surgical staging were enrolled. There were 51, 43 and 51 cases in group A (surgery with adjuvant therapy), group B (surgery only) and group C (control), respectively. Control cases were participants who had comparable demographic characteristics and underwent gynecological checkup during the period of study. In part of physical functioning, group B had statistically better scores than group A. Participant in group B and C reported significantly better QoL in part of social functioning than group A. Symptom severity; appetite loss and constipation in group B was statistically less than in group A. Constipation problems in group A and C were comparable. Participants in group C had worse global health status than group A/B. CONCLUSION: Adjuvant treatment with either radiation or chemotherapy had negative impacts on QoL in endometrial cancer survivors. It impacted physical health, social function, appetite loss, and constipation. All endometrial cancer survivors had global health scores better than healthy peers. Thoroughly counseling to endometrial cancer survivors remains an important tool for increasing awareness of treatment complications and lowering psychological emotional stress.

The functional neuroanatomy of musical memory in Alzheimer's disease.

BACKGROUND: Memory for music has attracted much recent interest in Alzheimer's disease but the underlying brain mechanisms have not been defined in patients directly. Here we addressed this issue in an Alzheimer's disease cohort using activation fMRI of two core musical memory systems. METHODS: We studied 34 patients with younger onset Alzheimer's disease led either by episodic memory decline (typical Alzheimer's disease) or by visuospatial impairment (posterior cortical atrophy) in relation to 19 age-matched healthy individuals. We designed a novel fMRI paradigm based on passive listening to melodies that were either previously familiar or unfamiliar (musical semantic memory) and either presented singly or repeated (incidental musical episodic memory). RESULTS: Both syndromic groups showed significant functional neuroanatomical alterations relative to the healthy control group. For musical semantic memory, disease-associated activation group differences were localised to right inferior frontal cortex (reduced activation in the group with memory-led Alzheimer's disease); while for incidental musical episodic memory, disease-associated activation group differences were localised to precuneus and posterior cingulate cortex (abnormally enhanced activation in the syndromic groups). In post-scan behavioural testing, both patient groups had a deficit of musical episodic memory relative to healthy controls whereas musical semantic memory was unimpaired. CONCLUSIONS: Our findings define functional neuroanatomical substrates for the differential involvement of musical semantic and incidental episodic memory in major phenotypes of Alzheimer's disease. The complex dynamic profile of brain activation group differences observed suggests that musical memory may be an informative probe of neural network function in Alzheimer's disease. These findings may guide the development of future musical interventions in dementia.

Sensitivity of Speech Output to Delayed Auditory Feedback in Primary Progressive Aphasias.

Delayed auditory feedback (DAF) is a classical paradigm for probing sensori-motor interactions in speech output and has been studied in various disorders associated with speech dysfluency and aphasia. However, little information is available concerning the effects of DAF on degenerating language networks in primary progressive aphasia: the paradigmatic "language-led dementias." Here we studied two forms of speech output (reading aloud and propositional speech) under natural listening conditions (no feedback delay) and under DAF at 200 ms, in a cohort of 19 patients representing all major primary progressive aphasia syndromes vs. healthy older individuals and patients with other canonical dementia syndromes (typical Alzheimer's disease and behavioral variant frontotemporal dementia). Healthy controls and most syndromic groups showed a quantitatively or qualitatively similar profile of reduced speech output rate and increased speech error rate under DAF relative to natural auditory feedback. However, there was no group effect on propositional speech output rate under DAF in patients with nonfluent primary progressive aphasia and logopenic aphasia. Importantly, there was considerable individual variation in DAF sensitivity within syndromic groups and some patients in each group (though no healthy controls) apparently benefited from DAF, showing paradoxically increased speech output rate and/or reduced speech error rate under DAF. This work suggests that DAF may be an informative probe of pathophysiological mechanisms underpinning primary progressive aphasia: identification of "DAF responders" may open up an avenue to novel therapeutic applications.

Anxiety and Depression in Thai Women with Abnormal Cervical Cytology who Attended Colposcopic Unit in Thammasat University Hospital

Background: Colposcopy is the standard investigation for women with abnormal cervical cytology. Waiting time to colposcopy could impact to psychological distress. Data about anxiety and depression in eastern countries patients were limited. Aim of this investigation was to evaluate anxiety and depression status in Thai women who were waiting for colposcopy compared to women who attended gynecology clinic for cervical cancer screening. Materials and methods: This study was conducted at the outpatient gynecology clinic of Thammasat University Hospital between January 2017 to March 2018. A Total of 200 women were recruited into the study. The cases were divided into the study and control group. Study group consisted of one hundred women with abnormal cervical cytology referred to colposcopy. One hundred of women who attended gynecology clinic for cervical cancer screening was classified as control group. The Hospital Anxiety and Depression Scale (HADS) was used to determine anxiety in the participants. Results: Total of 200 women who met criteria of the study were recruited. The mean ages of both groups were 40 years old. Both groups were significantly different when it came to their education, 30 and 59 percent of study and control group had education level more than bachelor (p=0.003). The prevalence of anxiety was statistically significantly higher in study group than the control group (15% and 6%, respectively). There was only one case of depression in study. Waiting time and abnormal cervical cytology severity did not affected to anxiety level. Conclusions: Colposcopy and appointment caused anxiety. However anxiety was not associated with waiting time to colposcopy or Pap result's severity.

Quality of Life in Cervical Cancer Survivors and Healthy Women: Thai Urban Population Study

Background : To determine a baseline quality of life (QoL) in cervical cancer survivors compared to that of healthy subjects in the tertiary Thammasat University Hospital, Thailand. Materials and Methods: The investigation was conducted at the outpatient gynecological department of Thammasat University Hospital between January and June 2016. A total of 192 women were entered into the study (97 cervical cancer survivors; 37 after radical hysterectomy (RH), 43 with concurrent chemoradiation (CRT), and 17 featuring both RH and CRT; and 95 control subjects from the same outpatient department with no history of malignancy). Participant QoL was assessed using a Thai version of the EORTC-QLQ-C30 (European Organization for Research Treatment of Cancer Quality-of-Life) and a general survey for the assessment of sociodemographic data was also conducted. Results: There were significant differences in physical, role, emotional and social functions between cervical cancer survivor and control groups. Global health, fatigue, pain, appetite loss, and financial difficulties also demonstrated statistically significant variation. Cervical cancer survivors treated by RH had higher scores for emotional and social function and global health than the control group. Moreover, they had less appetite loss, fatigue and financial difficulties. However, patients treated with CRT experienced more pain than the control group. All cervical cancer survivors had lower physical function scores than the control group. Conclusion: Quality of life in cervical cancer survivors is better than in healthy peers in some domains. Cervical cancer survivors treated with RH may have a better QoL than healthy peers. Early detection for early stage cervical cancer remains most important because treatment in early stages does not cause lowering of the QoL.

The Thai Version of the Addenbrooke's Cognitive Examination III.

The objective of our study was to assess the accuracy of the Thai version of the Addenbrooke's Cognitive Examination III (ACE-T). We used the ACE-T to assess 107 participants aged 60 or over, divided into the following groups: early dementia, n=30; mild cognitive impairment (MCI), n=29; and normal controls (NC), n=48. The ACE-T exhibited good internal consistency (0.93) and inter-rater reliability (1.0). The optimal cut-off score for the ACE-T to differentiate MCI from NC was 75/76, giving a sensitivity of 0.9 and specificity of 0.86. At the optimal cut-off of 61/62, the ACE-T had excellent sensitivity (1.0) and specificity (0.97) to distinguish early dementia from non-dementia. The ACE-T had high diagnosis accuracy in the detection of the MCI and early dementia in the Thai population.

The Speech-to-Song Illusion Is Reduced in Speakers of Tonal (vs. Non-Tonal) Languages.

The speech-to-song illusion has attracted interest as a probe of the perceptual interface between language and music. One might anticipate differential speech-to-song effects in tonal vs. non-tonal languages, since these language classes differ importantly in the linguistic value they assign to tones. Here we addressed this issue for the first time in a cohort of 20 healthy younger adults whose native language was either tonal (Thai, Mandarin) or non-tonal (German, Italian) and all of whom were also fluent in English. All participants were assessed using a protocol designed to induce the speech-to-song illusion on speech excerpts presented in each of the five study languages. Over the combined participant group, there was evidence of a speech-to-song illusion effect for all language stimuli and the extent to which individual participants rated stimuli as "song-like" at baseline was significantly positively correlated with the strength of the speech-to-song effect. However, tonal and non-tonal language stimuli elicited comparable speech-to-song effects and no acoustic language parameter was found to predict the effect. Examining the effect of the listener's native language, tonal language native speakers experienced significantly weaker speech-to-song effects than non-tonal native speakers across languages. Both non-tonal native language and inability to understand the stimulus language significantly predicted the speech-to-song illusion. These findings together suggest that relative propensity to perceive prosodic structures as inherently linguistic vs. musical may modulate the speech-to-song illusion.

Processing emotion from abstract art in frontotemporal lobar degeneration.

art may signal emotions independently of a biological or social carrier: it might therefore constitute a test case for defining brain mechanisms of generic emotion decoding and the impact of disease states on those mechanisms. This is potentially of particular relevance to diseases in the frontotemporal lobar degeneration (FTLD) spectrum. These diseases are often led by emotional impairment despite retained or enhanced artistic interest in at least some patients. However, the processing of emotion from art has not been studied systematically in FTLD. Here we addressed this issue using a novel emotional valence matching task on abstract paintings in patients representing major syndromes of FTLD (behavioural variant frontotemporal dementia, n=11; sematic variant primary progressive aphasia (svPPA), n=7; nonfluent variant primary progressive aphasia (nfvPPA), n=6) relative to healthy older individuals (n=39). Performance on art emotion valence matching was compared between groups taking account of perceptual matching performance and assessed in relation to facial emotion matching using customised control tasks. Neuroanatomical correlates of art emotion processing were assessed using voxel-based morphometry of patients' brain MR images. All patient groups had a deficit of art emotion processing relative to healthy controls; there were no significant interactions between syndromic group and emotion modality. Poorer art emotion valence matching performance was associated with reduced grey matter volume in right lateral occopitotemporal cortex in proximity to regions previously implicated in the processing of dynamic visual signals. Our findings suggest that abstract art may be a useful model system for investigating mechanisms of generic emotion decoding and aesthetic processing in neurodegenerative diseases.

Chicken Essence and Cognitive Function: A Systematic Review and Meta-Analysis.

OBJECTIVES: To determine the efficacy of chicken essence for improving cognitive performance. Material and Method: English language database including Embase, Medline, PsychINFO and Global Health (up to May 2014) were searched. Inclusion criteria were randomized double-blind controlled studies (RCT) or cross-over studies comparing chicken essence with placebo. Results: Four trials were included. Three studies measured cognitive performance, while the remaining study assessed cognitive performance after fatigue-inducing tasks. When compared to placebo, chicken essence improved arithmetic (SMD -1.23, 95% CI -2.51 to -0.31) and memory (SMD -3.94, 95% CI -4.59 to -3.29). There were no ascertainable positive effects on attention/concentration (SMD -1.55, 95% CI -4.77 to 1.67), anti-fatigue (SMD 1.20, 95% CI 0.53 to 1.88), and recovery from mental fatigue (SMD -0.38, 95% CI -1.0 to 0.25). However, the levels of evidence with respect to each cognitive domain was rated as 'very low' using the GRADE system because of low sample size, inconsistency and high risk of bias. Conclusion: There are few trials examining the efficacy of chicken essence to cognitive performance. Furthermore, the level of evidence was very low. Using it for this indication is not suggested at present. Additional high quality RCT designs are needed to arrive at a stronger conclusion.

Ginkgo biloba for prevention of dementia: a systematic review and meta-analysis.

OBJECTIVE: To determine the efficacy of Ginkgo biloba for the prevention of dementia in individuals without dementia. MATERIAL AND METHOD: English databases including Medline, Embase, Cochrane Library and PsycINFO, were searched, and randomized double-blind controlled studies comparing Ginkgo biloba with placebo in prevention of dementia were considered. Two trials met inclusion criteria. Methodological quality was assessed using the Jadad criteria. RESULTS: Meta-analysis of the two trials involving 5,889 participants indicated no significant difference in dementia rate between Ginkgo biloba and the placebo (347/2,951 vs. 330/2,938, odds ratio = 1.05, 95% CI 0.89-1.23) and there was no considerable heterogeneity between the trials. The two studies revealed no statistically significant differences in the rate of serious adverse effect between Ginko biloba and the placebo. CONCLUSION: There is no convincing evidence from this review that demonstrated Ginkgo biloba in late-life can prevent the development of dementia. Using it for this indication is not suggested at present.
