    BACKGROUND: It is not uncommon that anxiety and depression occur in patients with cancers, and past researches have shown that the quality of life of patients is negatively affected. This study aims to determine the prevalence of anxiety and depression of patients with haematological cancers in Malaysia and to investigate the possible association of these psychological symptoms with their quality of life.

    METHODS: This is a cross-sectional study where patients with haematological cancers attending two major hospitals were recruited. Anxiety and depression symptoms were assessed using the Hospital Anxiety and Depression scale (HADS). Quality of life (QoL) of these patients was measured using the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ C30). An overall summary QoL score in combination with financial difficulty score and global health score were used for analysis.

    RESULTS: A total of 319 patients were recruited. Thirty-three percent of patients had anxiety symptoms, 23.5% had depression symptoms. In summary the overall score of QoL is significantly lower in patients with higher scores for depression and anxiety, (p<0.05). Patients who exhibit anxiety symptoms were more frequently female, still undergoing treatment whereas patients who had higher depression scores were older and had acute leukemias or myeloproliferative neoplasms. Patients who have depression are significantly associated with a higher financial difficulty score, p<0.05.

    CONCLUSION: The poor quality of life in patients who have anxiety and depression should raise awareness amongst the health professions treating them so that additional support can be provided.

    Introduction: Nasopharyngeal Carcinoma (NPC) is the second most common cancer among men in Malaysia. Establishing local data will help to improve the treatment strategies and lower the anxiety and depression level among NPC patients. Our aim was to compare the level of symptoms of anxiety and depression and the coping strategies employed between NPC and cancer-free patients. Methods: A comparative cross-sectional study with universal sampling was conducted on 22 NPC patients and 30 cancer-free patients from the Oncology and Radiotherapy Department and Ear, Nose and Throat clinic of Hospital Kuala Lumpur (HKL) between 12 to 29 May 2008. In this study, the symptoms of depression and anxiety were obtained by using the Hospital Anxiety and Depression Scale (HADS) while Brief COPE questionnaire was used to understand patients’ coping strategies. Results: The prevalence of NPC was higher in the Chinese, men, aged between 40 and 59 years, and those from the lower income group. The levels of anxiety and depression symptoms were found to be higher in the NPC group as compared to the cancer-free group. However, only the level of depression was found significantly related to the NPC group (p=0.002). This study also found that the two comparison groups were
    using different types of coping strategies. The NPC patients mainly used ‘acceptance’ as their coping strategy while the comparative group most often used ‘religion’. Among the types of coping strategies reported by the patients, ‘use of instrumental support’ type was found to be associated with a lower level of anxiety (p = 0.035) and ‘humour’ type was associated with lower depressive symptoms (p = 0.269). On the contrary, ‘selfblame’ type was associated with both anxiety (p =0.0001) and depression (p = 0.001) symptoms. In addition, patients with different gender, ethnicity, educational levels, and
    monthly income were also found to have significant differences in their levels of anxiety and depression as well as type of coping strategies. Conclusions: NPC patients had higher anxiety and depression levels as compared to the comparative group. Different socio-demographic backgrounds and different types of coping strategies had an influence on patients resulting in different levels of anxiety and depression.

    Objective: This study was aimed to determine the prevalence of anxiety and depressive symptoms , to examine their association with health-related quality of life (HRQoL) profiles and to determine the predictors on overall HRQoL. Methods: This was a cross-sectional study conducted in Hospital Sultanah Nur Zahirah, Kuala Terengganu, Malaysia. The Malay Hospital Anxiety and Depression Scale (HADS) and McGill Quality of Life Questionnaire (MMQoL) were administered to a sample of 150 cancer patients (mean age = 50.4 years).
    Chi-square test, correlation and multiple regression were utilised for data analysis. Results: The prevalence for mild anxiety and depressive symptoms was 30.7% and 23.3% espectively. The HADS-A correlated strongest with Total MMQoL Score (r = - 0.578) and Psychological Well-Being (r = -0.526). Only HADS-A (beta = - 0.486), and HADS-D (beta = -0.173) were significant in predicting overall health-related quality of life. Conclusion: Findings in our study indicated that the prevalence of anxiety and depressive symptoms in
    Terengganu cancer patients are moderate. If anxiety and depression are identified and treated, health-related quality of life among oncology patients appropriately could significantly be improved.

    INTRODUCTION: In the context of collective efforts taken in Japan to control the spread of COVID-19, the state of emergency and social distancing have caused a negative impact on the mental health of all residents, including foreign communities in Japan. This study aimed to evaluate the level of anxiety and its associated factors among non-Japanese residents residing in Japan during the COVID-19 pandemic.

    METHODS: A web-based survey in 13 languages was conducted among non-Japanese residents living in Japan during the COVID-19 situation. The State-Trait Anxiety Inventory assessed the level of anxiety-State (STAI-S) scores prorated from its six-item version. The multivariable logistic regression using the Akaike Information Criterion (AIC) method was performed to identify the associated factors of anxiety among participants.

    RESULTS: From January to March 2021, we collected 392 responses. A total of 357 valid responses were analyzed. 54.6% of participants suffered from clinically significant anxiety (CSA). In multivariable logistic model analysis, the CSA status or the high level of anxiety was associated with three factors, including having troubles/difficulties in learning or working, decreased sleep duration, and decreased overall physical health (p<0.05).

    CONCLUSION: Our study suggests several possible risk factors of anxiety among non-Japanese residents living in Japan undergoing the COVID-19 pandemic, including the troubles or difficulties in learning or working, the decrease in sleep duration, and the decrease in overall physical health.

    In response to the coronavirus disease 2019 (COVID-19) pandemic, healthcare providers are exposed to psychological and mental health implications, including vicarious traumatization, anxiety, and depression. Gradual increases in the number of COVID-19 cases meant they were inadequately protected from contamination due to a shortage of protective equipment, excessive workloads, emotional exhaustion and frustration. These circumstances affect their work performance in delivering health services. This study aims to compare the levels of anxiety in frontline and non-frontline healthcare providers during the COVID-19 pandemic. This study applied a comparative cross-sectional design between May and July 2020 at the Hospital Raja Perempuan Zainab II. Convenient sampling was applied in the selection of eligible participants. The case report form contained two self-administered questionnaires, namely, The Hospital Anxiety and Depression Scale and Medical Outcome Study Social Support Survey. Descriptive analysis, analysis of variance, and analysis of covariance were conducted using SPSS version 26. The number of participants recruited was 306, including 160 healthcare providers in the frontline group and 146 in the non-frontline group. The non-frontline healthcare providers reported a significantly higher anxiety mean score of 1.7 than the frontline providers after adjusting for gender, duration of employment, and social support. It indicates that non-frontline healthcare providers require psychological support similar to that of frontline healthcare providers during the COVID-19 pandemic.

    OBJECTIVE: Use of the Screen for Child Anxiety Related Emotional Disorders (SCARED) has increased significantly since its publication. Although the validity of the SCARED is well established, most of the samples investigated primarily comprised Caucasian children and, where available, people from Asian cultures such as China. Furthermore, the instrument's utility for screening use in community samples has yet to be validated, although it is commonly advocated for this use. The present study addressed the psychometric properties of the SCARED in a community sample of Malaysian children and adolescents.

    METHOD: A total of 386 participants from an urban area, aged between 8 and 17, completed the 41-item SCARED. Confirmatory factor analysis and exploratory factor analysis were performed to investigate the factor structure of the SCARED.

    RESULTS: Internal consistency ratings for the SCARED's total and subscale scores were good, except for School Avoidance. The validity of the SCARED was further demonstrated through a significant correlation with the Internalizing subscale of the Strength and Difficulties Questionnaire (SDQ). In contrast with the five-factor structure proposed for primarily Caucasian samples, factor analysis revealed a four-factor structure for this Malaysian sample.

    CONCLUSIONS: These research findings support the validity of the SCARED and its utility as a screening tool in a community sample of Malaysian children and adolescents.

    BACKGROUND: It is hypothesized that anxiety and behavioral responses are intense at the beginning of an epidemic. The objective of this study was to investigate anxiety symptoms and use of preventive measures against COVID-19. The study also compared the association between preventive measures and anxiety symptoms during the week immediately preceding the study and those symptoms and measures at the beginning of the outbreak.

    METHODS: A cross-sectional population survey using an online questionnaire commenced on 14 February 2020. The study participants were residents of Taiwan ages 20 to 70 years. The 6-item state version of the State-Trait Anxiety Inventory (STAI-6) was used to assess anxiety symptoms. The questions about preventive measures asked participants about their personal protection, cough etiquette, contact precautions, voluntary quarantine, and prompt reporting. Multivariable logistic regression was used to determine the factors influencing an increase in the preventive measures scores.

    RESULTS: Of a total of 3555 completed responses, a total of 52.1% (95% confidence interval [CI] 50.4-53.7) of the respondents reported moderate to severe levels of anxiety symptoms in the past week, whereas 48.8% (95%CI 47.2-50.5) reported moderate to severe anxiety symptoms at the beginning of the outbreak. With a higher score indicating greater anxiety, the median scores for anxiety symptoms in the past week and at the beginning of the outbreak were 46.7 (IQR [interquartile range] 36.7-53.3) and 43.3 (IQR 36.7-53.3), respectively. The median scores for the preventive measures taken in the past week and at the beginning of the outbreak were 26.0 (IQR 21.0-30.0) and 24.0 (IQR 19.0-28.0), respectively, out of a maximum score of 36. In the multivariable analysis, an increased anxiety symptom score from the beginning of the outbreak to the past week (adjusted OR = 7.38, 95%CI 6.28-8.66) was a strongly significant determinant of an increased preventive measures score in the past week compared with the score at the beginning of the outbreak.

    CONCLUSIONS: Anxiety and preventive measures scores were high and increased with the epidemic rate. Higher anxiety was associated with an increased use of preventive measures against COVID-19.

    The aim of the study was to determine coping strategies among breast cancer patients with depression and anxiety during chemotherapy. Methods: Breast cancer patients with confirmed diagnosis who were undergoing out-patient chemotherapy at the Oncology Unit, University Malaya Medical Centre were invited to participate in the study. They were assessed on their socio demographic profiles and clinical history. The Hospital Anxiety Depression Scale (HADS) was used by patients to report anxiety and depression. The Brief COPE Scale was used to assess coping strategies among the patients. Results: One hundred and forty one patients with mean age of fifty years participated in the study. Prevalence for depression was 19.1% and prevalence for anxiety was 24.1%. Patients who were having anxiety symptoms scored significantly higher on denial, behavioural disengagement and venting as their coping strategies compared to patients who were not anxious. Patients with depressive symptoms scored significantly higher in behavioural disengagement and self-blame as their coping strategies compared to those who were not depressed. Conclusion: Breast cancer patients undergoing chemotherapy experienced high level of depressive and anxiety symptoms. However different coping strategies were adopted to cope with their illness, chemotherapy treatment, practical and family problems, emotional and physical symptoms.

    INTRODUCTION: Hyperemesis Gravidarum (HG) is a severe form of vomiting that occurs among pregnant mothers. Due to the nature of HG, pregnant mothers may feel fatigued and burdened by it and questions have been raised about the emergence of psychiatric illness during this period of vulnerability.

    METHODS: A comparative cross-sectional study using Hospital Anxiety and Depression Scale (HADS), M.I.N.I (MINI International Neuropsychiatric Interview) and ENRICH- EMS (Evaluation and Nurturing Relationship Issues, Communication and Happiness - Marital Satisfaction Scale) were performed in a group of 112 pregnant women.

    RESULTS: There were no differences in the prevalence rate of any anxiety disorder among the patient with HG vs comparative group (9% vs 3%, P > 0.05) and depressive disorder in women with HG vs comparative group (16% vs 8%, P > 0.05) respectively. There were associations between HG and gravida, past history of miscarriage, and gestational diabetes (P

    Stress tends to worsen the prognosis of patients with coronary heart disease. The aim of the study is to determine the relationship between stress related psychosocial factors like anxiety, depression and life events and temporally cardiac events specified as acute myocardial infarction and unstable angina 65 subjects with confirmed myocardial infarction or unstable angina were interviewed using 2 sets of questionnaire, the Hospital Anxiety and Depression Scale (HADS) and Life Changes Stress Test, a segment of the Rahe's Stress and Coping Inventory first at time of occurrence of their cardiac event and the second time was 6 months later. Anxiety, depression and life events scores were calculated for both and recurrence of cardiac event for the 6 month duration was also recorded. Patients who had significant levels of depression and or life events were ten times more likely to have recurrence of cardiac events as compared to those without risk for either of these psychological symptoms. Anxiety, depression and stress levels are significantly increased after the onset of ischemic heart disease and could be contributing or predisposing factors for the recurrence of cardiac events for these patients.

    OBJECTIVE AND BACKGROUND:
    The role of psychological disturbance in the pathogenesis of functional dyspepsia is uncertain. We aimed to examine for differences in anxiety, depression and health-related quality of life (HRQOL) between adults with organic (OD) and functional dyspepsia (FD).

    METHODOLOGY:
    A prospective, cross-sectional study of Malaysian adults undergoing oesophago-gastro-duodenoscopy (OGDS) for the primary indication of dyspepsia was conducted. Prior to OGDS, locally translated and validated versions of the Hospital Anxiety and Depression Scale (HADS), Nepean Dyspepsia Index (NDI) and Leeds Dyspepsia Questionnaire (LDQ) were administered.

    RESULTS:
    839 patients (mean age 49.6 ± 15.8 years, 55.7% female, ethnic division: Malays 30.5% , Chinese 38.4%, Indians 29.4%) were studied between June 2008 and March 2009. 472 (56.3%) and 367 (43.7%) patients had FD and OD respectively. There was no difference in the mean LDQ score between FD and OD patients (18.6 vs 18.1, P = 0.4). Moderate/severe anxiety was more prevalent in FD compared to OD patients (28.5% vs 23.1%, P = 0.05) but there was no significant difference in depression. Summary scores for the NDI revealed a lower mean value in FD patients compared to OD patients (68.6 ± 19.5 vs 71.4 ± 19.6, P = 0.04).

    CONCLUSION:
    Patients with FD have a lower HRQOL compared to those with OD, but this could not be attributed to differences in anxiety nor depression between both groups.

    BACKGROUND: Medical education is known to be highly stressful and challenging. Many medical students suffer from psychological stress which may lead to burnout and poor academic performances. Quality of life (QOL) of medical students is also affected. In this study, we aim to determine the prevalence of anxiety and depression of the senior medical students and to assess their QOL.

    METHODS: This is a cross-sectional study which involved medical students in their final two years of study at a public university in Malaysia. Self-administered Hospital Anxiety and Depression scale (HADS) and World Health Organisation QOL questionnaire (WHOQOL-BREF) were used to assess their psychological symptoms and QOL.

    RESULTS: A total 149 students participated. The prevalence rates of anxiety and depression were 33% and 11% respectively. Malay students had significantly more anxiety compared to the other ethnic groups, P<0.05. Female students had significantly lower psychological score compared to male; 70.73 vs 66.32(P<0.05). Anxiety and depression were associated with significantly poorer QOL. Students with depression symptoms were associated with lower physical, psychological and environmental domain score whereas those with anxiety had lower psychological, social and environmental scores, P<0.05. Overall QOL score was significantly lower in Chinese students (P<0.05) and those with depression (P<0.001).

    CONCLUSION: QOL of medical students are significantly affected by the presence of anxiety and depression. It is recommended that medical schools implement measures which can identify students at risk and to offer comprehensive intervention and preventive programmes to improve the students' wellbeing.

    Knowledge on psychiatric comorbidity in adult ADHD is essential for prevention, detection, and treatment of these conditions. This review (1) focuses on large studies (n > 10,000; surveys, claims data, population registries) to identify (a) overall, (b) sex- and (c) age-specific patterns of comorbidity of anxiety disorders (ADs), major depressive disorder (MDD), bipolar disorder (BD) and substance use disorders (SUDs) in adults with ADHD relative to adults without ADHD; and (2) describes methodological challenges relating to establishing comorbidity in ADHD in adults as well as priorities for future research. Meta-analyses (ADHD: n = 550,748; no ADHD n = 14,546,814) yielded pooled odds ratios of 5.0(CI:3.29-7.46) for ADs, 4.5(CI:2.44-8.34) for MDD, 8.7(CI:5.47-13.89) for BD and 4.6(CI:2.72-7.80) for SUDs, indicating strong differences in adults with compared to adults without ADHD. Moderation by sex was not found: high comorbidity held for both men and women with sex-specific patterns as in the general population: higher prevalences of ADs, MDD and BD in women and a higher prevalence of SUDs in men. Insufficient data on different phases of the adult lifespan prevented conclusions on developmental changes in comorbidity. We discuss methodological challenges, knowledge gaps, and future research priorities.

    This study presents anxiolytic- and antidepressant-like effects of a methanolic extract of Morinda citrifolia Linn. (noni) fruit (MMC) in well-established mouse models of anxiety and depression. The administration of MMC (1 g/kg, p.o.) and diazepam (1 mg/kg, i.p.) significantly attenuated anxiety-like behaviour in mice by increasing the percentage of time spent and number of entries in the open arms in the elevated plus maze (EPM), and significantly enhanced the exploration in the light box in the light/dark test (LDT). The pre-treatment with flumazenil (6 mg/kg, i.p.) or bicuculline (3 mg/kg, i.p.) or WAY 100635 (1 mg/kg, i.p.) antagonized the anxiolytic-like effect elicited by MMC (1 g/kg, p.o.). These results suggest the possible involvement of benzodiazepine-GABAAergic and serotonergic mechanisms in the anxiolytic-like effect of noni fruit. Meanwhile, in the antidepressant study, the administration of MMC (0.5 and 0.75 g/kg, p.o.) and desipramine (30 mg/kg, i.p.) significantly reduced the duration of immobility in the tail suspension test (TST). Furthermore, pre-treatment of mice with 4-chloro-DL-phenylalanine methyl ester hydrochloride (PCPA; 100 mg/kg, i.p., an inhibitor of serotonin synthesis) for four consecutive days or a single dose of WAY 100635 (1 mg/kg, i.p., 5HT1A receptor antagonist) or α-methyl-DL-tyrosine (AMPT; 100 mg/kg, i.p., an inhibitor of noradrenaline synthesis) significantly reversed the anti-immobility effect of MMC (0.5 g/kg, p.o.) in TST by indicating the specific involvement of the serotonergic and noradrenergic systems in the antidepressant-like effect of noni fruit. Taken together, these findings suggest that MMC has both anxiolytic- and antidepressant-like activities to be resorted as a valuable alternative therapy for comorbid anxiety and depressive conditions.

    The effects of mitragynine on anxiety-related behaviours in the open-field and elevated plus-maze tests were evaluated. Male Sprague-Dawley rats were orally treated with mitragynine (10, 20 and 40 mg/kg) or diazepam (10 mg/kg) 60 min before behavioural testing. Mitragynine doses used in this study were selected on the basis of approximately human equivalent doses with reference to our previous literature reports. Acute administration of mitragynine (10, 20 and 40 mg/kg) or diazepam (10 mg/kg) increased central zone and open arms exploration in the open-field and elevated plus-maze tests respectively. These anxiolytic-like effects of mitragynine were effectively antagonized by intraperitoneal administration of naloxone (2 mg/kg), flumazenil (10 mg/kg), sulpiride (0.5 mg/kg) or SCH 23390 (0.02 mg/kg) 15 min before mitragynine treatments. These findings reveal that the acute administration of mitragynine produces anxiolytic-like effects and this could be possibly attributed to the interactions among opioidergic, GABAergic and dopaminergic systems in brain regions involved in anxiety.
