    Introduction: Anxiety is a common mental health disorder in primary care, with a higher prevalence among women compared to men.
    Aim: This is the first study to validate the Generalised Anxiety Disorder-7 questionnaire (GAD-7) as a case-finding instrument for anxiety in a primary care setting in Malaysia. The objective was to determine the diagnostic accuracy of the Malay version of the GAD-7 in detecting anxiety among women.
    Methods: This cross-sectional study was conducted in a government-funded primary care clinic in Malaysia. Consecutive women participants attending the clinic during data collection were given self-administered questionnaires including the GAD-7 (Malay version). Participants then were selected using systematic weighted random sampling for Composite International Diagnostic Interviews (CIDI). The GAD-7 was validated against the CIDI reference standard.
    Results: The response rate was 87.5% for the questionnaire completion (895/1023), and 96.8% for diagnostic interviews (151/156). The prevalence of anxiety was 7.8%. The GAD-7 had a sensitivity of 76% (95% CI 61%–87%), a specificity of 94% (88%–97%), positive LR 13.7 (6.2–30.5) and negative LR 0.25 (0.14–0.45).
    Discussion: The Malay version of the GAD-7 was found to be valid and reliable in case-finding for anxiety in this study. Due to its brevity, it is a suitable case-finding instrument for detecting anxiety in primary care settings in Malaysia.

    BACKGROUND: Urinary Incontinence (UI) is when a person is unable to hold his/her urine effectively. This is a common problem which can develop and worsen during pregnancy. An effective way to manage UI is to educate patients on the Pelvic Floor Muscle Exercise (PFME) regularly. The present study aimed to ascertain the pregnant women's knowledge, attitudes, and practices (KAP) related to PFME.

    METHODS: This was a cross-sectional study done in a one primary care clinic located in a semi-urban area in Selangor, Malaysia. Simple random sampling was conducted among pregnant women aged 18 years old and above at any gestation. The validated study instruments used consisted of questions on socio-demography, KAP on UI, and also the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form to determine UI among the respondents.

    RESULTS: The response rate for this study was 72.1%, where 440 pregnant women consented to take part in the study. The median age of study respondents was 30 years old and majority of the study respondents was from the Malay ethnicity (80.9%). The prevalence of UI was 40.9%. The proportion of pregnant women with good knowledge, attitude and practice scores were 58.0%, 46.6% and 45.2% respectively. There was a significant association between UI and age (p = .03), body mass index (p = .03), ethnicity (p = .04), gravida. (p = .001), knowledge on PFME (p = .007) and attitude towards PFME (p = .006).

    CONCLUSIONS: Findings from this study fill a gap in the prevalence and KAP concerning PFME at the primary care level. The foundation areas for future education and health promotion on UI should address the importance of correct PFME. This education can be delivered through a pragmatic way to ensure its effectiveness and sustainability of the health promotion program.

    Depression is commonly observed in university students, who are a high risk group for developing psychiatric disorders during adulthood. This study aimed to determine the prevalence of depression and its traditional Chinese medicine body constitutions and psychological determinants among university students in Malaysia. A cross-sectional pilot study was conducted between 9 and 28 September 2020 among 80 university students in Malaysia. Participants completed online survey questionnaires, including the validated Patient Health Questionnaire (PHQ-9), Constitution in Chinese Medicine Questionnaire (CMCQ), Dysfunctional Attitude Scale (DAS), Depression Anxiety Stress Scale (DASS-21) stress subscale, Perceived Stress Scale (PSS-10), and Rosenberg Self-Esteem Scale (RSES), which assess depression, body constitution, dysfunctional attitude, stress, perceived stress, and self-esteem. Multiple linear regression analyses were performed to determine the associated risk factors for depression. The overall prevalence of depression among university students was 33.8%. The multiple regression analysis showed a significant relationship between depression and qi-stagnation constitution (B = 0.089, p = 0.011), balanced constitution (B = -0.077, p = 0.049), and self-esteem (B = -0.325, p = 0.001). Our findings suggest that some traditional Chinese medicine body constitutions and self-esteem are significant risk factors affecting depression among university students. Identifying risk factors of depression is vital to aid in the early detection of depression among university students.

    Hepatocellular carcinoma (HCC) is the most common primary liver cancer and its diagnosis on routine stains is usually straightforward, except in some cases where there may be difficulty in distinguishing HCCs from metastatic carcinomas (MC) and cholangiocarcinomas (CC). Hepatocyte Paraffin 1 antibody (Hep Par 1) is a new monoclonal antibody which reacts with normal and neoplastic hepatocytes, and this study aims to determine its specificity and sensitivity in distinguishing hepatocellular carcinoma (HCC) from cholangiocarcinoma (CC) and metastatic carcinomas (MC). Hep Par 1 antibody was applied to 28 cases of HCC, 22 cases of MC from varying sites and 8 CCs, and produced a strong, diffuse, granular, cytoplasmic staining of all benign hepatocytes. 23 out of 28 cases of HCC showed heterogeneously positive staining for Hep Par 1 irrespective of their degree of differentiation, while 2 out of 8 cases of cholangiocarcinoma were positive for Hep Par 1, and all 22 cases of metastatic carcinoma were negative. The sensitivity and specificity of Hep Par 1 for HCC was 82.1% and 93.3% respectively; whereby the antibody was noted to show occasional false positivity in cases of cholangiocarcinoma and non-neoplastic bowel mucosa, while its variable staining in HCC produced false negative results in some small biopsies. Thus, Hep Par 1 should be used in a panel with other antibodies to obtain useful information in distinguishing HCC from CC and MC.

    INTRODUCTION: Diabetes-related distress (DRD) refers to patient's concerns about diabetes mellitus, its management, need of support, emotional burden and access to healthcare. The aim of this study was to translate and examine the psychometric properties of the Malay version of the 17-item Diabetes Distress Scale (MDDS-17) in adult patients with type 2 diabetes mellitus (T2D).
    METHODS: A standard procedure was used to translate the English 17-items Diabetes Distress Scale into Malay language. We used exploratory factor analysis (EFA) with principal axis factoring and promax rotation to investigate the factor structure. We explored reliability by internal consistency and 1-month test-retest reliability. Construct validity was examined using the World Health Organization quality of life-brief questionnaire, Morisky Medication Adherence Scale, Patient Health Questionnaire and disease-related clinical variables.
    RESULTS: A total of 262 patients were included in the analysis with a response rate of 96.7%. A total of 66 patients completed the test-retest after 1 month. EFA supported a three-factor model resulting from the combination of the regimen distress (RD) and interpersonal distress (IPD) subscales; and with a swapping of an item between emotional burden (EB; item 7) and RD (item 3) subscales. Cronbach's α for MDDS-17 was 0.94, the combined RD and IPD subscale was 0.925, the EB subscale was 0.855 and the physician-related distress was 0.823. The test- retest reliability's correlation coefficient was r = 0.29 (n = 66; p = 0.009). There was a significant association between the mean MDDS-17 item score categories (<3 vs ≥3) and HbA1c categories (<7.0% vs ≥7.0%), and medication adherence (medium and high vs ≥low). The instrument discriminated between those having diabetes-related complication, low quality of life, poor medication adherence and depression.
    CONCLUSION: The MDDS-17 has satisfactory psychometric properties. It can be used to map diabetes-related emotional distress for diagnostic or clinical use.

    Depression is characterized by symptoms like disturbance in behavior, cognition and mood. This is commonly known to affect people aged 60 years and above especially those who are also afflicted with illnesses. The objectives of this study were to determine the prevalence of depression and its associated factors among the elderly in a tertiary care centre in Wilayah Persekutuan. A cross sectional study design was done. Stratified cluster sampling method was used to select the respondents. All elderly patients were selected from the orthopaedic, surgical, gynaecology and medical wards in a government hospital in Wilayah Persekutuan. A 30-item Geriatric Depression Scale questionnaire was used as a screening instrument. Out of the 246 elderly subjects, 198 were interviewed giving a response rate of 80.5%. The results showed that 54% of the elderly respondents were found to have depressive symptoms. Age (p=0.022), sex (p=0.008), ethnicity (p=0.022) and functional disabilities in bathing (p=0.001), grooming (p=0.007), dressing (p= 0.007), using the toilet (p=0.002), transferring from bed to chair and back (p=0.000), mobility (p=0.000) and climbing stairs (p=0.000) were all found to be significantly associated with depression among the elderly respondents. The outcome of this study will have an important impact on the implementation of the health policy for the elderly patients admitted to hospitals.

    OBJECTIVES: The aim of this study was to determine the: (1) prevalence of undernutrition as determined by the 'DETERMINE Your Nutritional Health Checklist' (NHC) and (2) factors independently associated with undernutrition among the older residents of these publicly funded shelter homes in Peninsular Malaysia.
    DESIGN: A total of 1081 elderly people (59%M) over the age of 60 y were surveyed using questionnaires determining baseline demographics, nutritional and cognitive status, physical function and psychological well-being.
    SETTING: Shelter homes, Peninsular Malaysia.
    RESULTS: In all, 41.4% (n = 447) were nourished (score <3), 32.1% (n = 347) at moderate risk (score between 3 and 5) and 26.6% (n = 287) were at high risk of undernutrition (score>5) according to the NHC. A large proportion of subjects were underweight with 14.3% of subjects recording a low body mass index (BMI) <18.5 kg/m2 and a further 18.2% recording a BMI between 18.5 and 20 kg/m2. The residential geriatric depression score (GDS-12R) (relative risk (RR) = 1.03 (95% confidence interval (CI) 1.01-1.05); P = 0.002) and the number of illnesses (RR = 1.14 (95% CI 1.07-1.21); P < 0.001) were found to be independently associated with nutritional risk (NHC score > or = 3). Using a BMI < 18.5 kg/m2 as an objective marker for nutritional risk, the NHC was shown to have a sensitivity of 66.4% (95% CI 58.0-74.2%), specificity of 42.7% (95% CI 39.3-46.1%), positive predictive value of 16.2% (95% CI 13.3-19.5%) and a negative predictive value of 88.4% (95% CI 84.9-91.4%).
    CONCLUSIONS: Many elderly people residing in publicly funded shelter homes in Malaysia may be at-risk of undernutrition, and were underweight. The NHC is better used as an awareness tool rather than as a screening tool.

    AIM: There are an estimated 372 000 worldwide deaths by drowning every year, and it has been described as a secret epidemic in Bangladesh. The aim of this study was to develop an intervention package to prevent children under the age of five from drowning in rural Bangladesh.

    METHODS: This was a qualitative study using focus group discussions in three villages in rural Bangladesh. The 45 participants were mothers and fathers with children under five, the parents of children who had drowned and community leaders.

    RESULTS: The majority of the participants (71%) were male. The focus groups revealed that most drowning's occurred between 11am and 2pm and that risk factors included the following: children not being able to swim, ditches that were not filled in, lack of medical facilities, parents who were not aware of childhood drowning and lack of information through the media about how to prevent of childhood drowning. Suggestions included using a mobile-based short messaging service or voice calls to parents, especially mothers, could increase awareness and reduce the risk of childhood drowning.

    CONCLUSION: A safety education programme could be effective in increasing knowledge and changing attitudes, which could prevent drowning among children in Bangladesh.

    Imbalances and deficiencies of nutrients are particularly prevalent among the elderly, resulting in increased risk of illness and impaired outcome, as well as reduced quality of life. A cross-sectional study was conducted to assess the nutritional risk and to determine its association with physical and mental health problems among the elderly in a semiurban community in the District of Hulu Langat, Selangor. Elderly people aged 60 years and above were included in the study, conducted from 11th March to 10th May 2004. Data were collected using a questionnaire-guided interview method. The Nutrition Screening Initiative Checklist (NSI-13) was used to assess the level (low, moderate, high) of nutritional risk of the subjects. The questionnaire also included the Barthel Index, Geriatric Depression Scale (GDS-30) and Elderly Cognitive Assessment Questionnaire (ECAQ) to identify functional status, depressive symptoms and cognitive impairment respectively, among the respondents. Out of 316 elderly residents, 300 agreed to participate in the study (response rate 94.9%). Respondents aged from 60 to 93 years old and the mean age was 67.08±6.6. Prevalence of moderate and high nutritional risks were 25.3% and 36.3% respectively. Nutritional risks were found to be significantly associated with age (p=0.015), marital status (p=0.00), chronic illness (p=0.000), functional disability (p=0.000) and depressive symptoms (p=0.010). In conclusion, the health status of the elderly strongly depends on their nutritional risk. Age, marital status, chronic illness, functional disability and depressive symptoms are factors to be emphasised when assessing the nutritional risk of the elderly.

    The Community Follow-up Project (CFUP) is a project where medical students choose a hospital in-ward patient during their clinical ward-based attachments and follow-up this patient's progress after discharge from the hospital. The students do a series of home visits and also accompany their patients for some of their follow-ups at the hospital, government clinics, general practitioners' clinics and even to the palliative care or social welfare centres. The students assess the physical, psychological and social impact of the illness on the patient, family and community. By following their patients from the time their patients were in the hospital and back to their homes and community, the students are able to understand in depth the problems faced by patients, the importance of communication skills in educating patients on their illness and the importance of good communication between primary, secondary and tertiary care.

    BACKGROUND: Screening for major depression with the Patient Health Questionnaire-9 (PHQ-9) can be done using a cutoff or the PHQ-9 diagnostic algorithm. Many primary studies publish results for only one approach, and previous meta-analyses of the algorithm approach included only a subset of primary studies that collected data and could have published results.

    OBJECTIVE: To use an individual participant data meta-analysis to evaluate the accuracy of two PHQ-9 diagnostic algorithms for detecting major depression and compare accuracy between the algorithms and the standard PHQ-9 cutoff score of ≥10.

    METHODS: Medline, Medline In-Process and Other Non-Indexed Citations, PsycINFO, Web of Science (January 1, 2000, to February 7, 2015). Eligible studies that classified current major depression status using a validated diagnostic interview.

    RESULTS: Data were included for 54 of 72 identified eligible studies (n participants = 16,688, n cases = 2,091). Among studies that used a semi-structured interview, pooled sensitivity and specificity (95% confidence interval) were 0.57 (0.49, 0.64) and 0.95 (0.94, 0.97) for the original algorithm and 0.61 (0.54, 0.68) and 0.95 (0.93, 0.96) for a modified algorithm. Algorithm sensitivity was 0.22-0.24 lower compared to fully structured interviews and 0.06-0.07 lower compared to the Mini International Neuropsychiatric Interview. Specificity was similar across reference standards. For PHQ-9 cutoff of ≥10 compared to semi-structured interviews, sensitivity and specificity (95% confidence interval) were 0.88 (0.82-0.92) and 0.86 (0.82-0.88).

    CONCLUSIONS: The cutoff score approach appears to be a better option than a PHQ-9 algorithm for detecting major depression.

    OBJECTIVE: The 21-item Depression, Anxiety and Stress Scale (DASS-21) is frequently used in non-clinical research to measure mental health factors among adults. However, previous studies have concluded that the 21 items are not stable for utilization among the adolescent population. Thus, the aims of this study are to examine the structure of the factors and to report on the reliability of the refined version of the DASS that consists of 12 items.
    METHOD: A total of 2850 students (aged 13 to 17 years old) from three major ethnic in Malaysia completed the DASS-21. The study was conducted at 10 randomly selected secondary schools in the northern state of Peninsular Malaysia. The study population comprised secondary school students (Forms 1, 2 and 4) from the selected schools.
    RESULTS: Based on the results of the EFA stage, 12 items were included in a final CFA to test the fit of the model. Using maximum likelihood procedures to estimate the model, the selected fit indices indicated a close model fit (χ(2)=132.94, df=57, p=.000; CFI=.96; RMR=.02; RMSEA=.04). Moreover, significant loadings of all the unstandardized regression weights implied an acceptable convergent validity. Besides the convergent validity of the item, a discriminant validity of the subscales was also evident from the moderate latent factor inter-correlations, which ranged from .62 to .75. The subscale reliability was further estimated using Cronbach's alpha and the adequate reliability of the subscales was obtained (Total=76; Depression=.68; Anxiety=.53; Stress=.52).
    CONCLUSION: The new version of the 12-item DASS for adolescents in Malaysia (DASS-12) is reliable and has a stable factor structure, and thus it is a useful instrument for distinguishing between depression, anxiety and stress.

    Self-esteem is an important determinant of psychological well-being that is particularly problematic during adolescent life stage. There is a correlation between low self-esteem and other social problems among today's adolescents. This study was conducted to determine the mean self-esteem score, and to determine the association between self-esteem and age, sex, race, religion, number of siblings, ranking among siblings, family function, parental marital status and smoking among adolescents aged 12 to 20-years-old. A cross sectional study design using random cluster sampling method was done. Four out of a total of 35 secondary schools in Klang District, Selangor were selected. Respondents consisted of individual students in selected classes from the four selected schools. Data was collected using a self-administered, structured, pre-tested questionnaire and was analyzed using the SPSS version 12.0. Out of 1089 respondents, 793 completed the questionnaire (response rate 73.82%). The overall mean self-esteem score was 27.65. The mean self-esteem score for males (27.99) was slightly higher than females (27.31). The differences in the mean scores by race were statistically significant. There was a statistically significant relationship between mean self-esteem scores and sex, age, race, religion, number of siblings, smoking and family function. There was no statistically significant difference between mean self-esteem score with parental marital status and with ranking among siblings. The overall mean self-esteem score was 27.65. Self-esteem was associated with sex, age, race, religion, number of siblings, smoking and family function.

    OBJECTIVE: To determine the diagnostic accuracy of the two questions with help question (TQWHQ) in the Malay language. The two questions are case-finding questions on depression, and a question on whether help is needed was added to increase the specificity of the two questions.
    METHOD: This cross sectional validation study was conducted in a government funded primary care clinic in Malaysia. The participants included 146 consecutive women patients receiving no psychotropic drugs and who were Malay speakers. The main outcome measures were sensitivity, specificity, and likelihood ratios of the two questions and help question.
    RESULTS: The two questions showed a sensitivity of 99% (95% confidence interval 88% to 99.9%) and a specificity of 70% (62% to 78%), respectively. The likelihood ratio for a positive test was 3.3 (2.5 to 4.5) and the likelihood ratio for a negative test was 0.01 (0.00 to 0.57). The addition of the help question to the two questions increased the specificity to 95% (89% to 98%).
    CONCLUSION: The two qeustions on depression detected most cases of depression in this study. The questions have the advantage of brevity. The addition of the help question increased the specificity of the two questions. Based on these findings, the TQWHQ can be strongly recommended for detection of depression in government primary care clnics in Malaysia. Translation did not apear to affect the validity of the TQWHQ.

    BACKGROUND: Pregnant women have an increased risk of urinary incontinence (UI), affecting their quality of life (QoL). This study aims to determine UI and its relationship with QoL among incontinent pregnant women.

    METHODS: This was a cross-sectional study in a semi-urban primary care clinic in Selangor, Malaysia, among pregnant women aged 18 years old and above. The validated study instruments consisted of questions on socio-demography, the International Consultation on Incontinence Questionnaire-UI Short Form (ICIQ-UI SF) to determine UI and the International Consultation on Incontinence Questionnaire Lower Urinary Tract Symptoms Quality of Life Module (ICIQ-LUTSQoL) to assess their QoL. A generalised linear model was used to determine the association between the continent and incontinent pregnant women with QoL.

    RESULTS: Of the approached 610 respondents, 440 consented to participate in the study, resulting in a response rate of 72.1%. The mean age was 29.8 years old (SD 4.69) with 82.2% (n = 148) having stress UI. Significant independent factors related to the decreased QoL were mid to late trimester (OR 3.06, 95% CI 1.48-6.32), stress UI, (OR 6.94, 95%CI 4.00-12.04) and urge UI (OR3.87, 95%CI 0.48-31.28). Non-Malay improved QoL (OR 0.29, 95% CI 0.16-0.52).

    CONCLUSIONS: All types of UI significantly affecting pregnant women's QoL. This information is useful in enhancing antenatal management at the primary care level, whereby they should be screened for UI and provided with effective early intervention to improve their QoL.

    Pulmonary overinflation syndrome (POIS) is a group of barotrauma-related diseases caused by the expansion of gas trapped in the lung, or over-pressurization of the lung with subsequent over-expansion and rupture of the alveolar air sacs. This group of disorders includes arterial gas embolism, tension pneumothorax, mediastinal emphysema, subcutaneous emphysema and rarely pneumopericardium. In the case of diving activities, POIS is rarely reported and is frequently related to unsafe diving techniques. We report a classical case of POIS in an underwater logger while cutting trees for logs in Tasik Kenyir, Terengganu. The patient, a 24-year-old worker, made a rapid free ascent to the surface after his breathing equipment malfunctioned while he was working underwater. He suffered from bilateral tension pneumothoraces, arterial gas embolism giving rise to multiple cerebral and cerebellar infarcts, mediastinal and subcutaneous emphysema as well as pneumopericardium. He was treated in a recompression chamber with hyperbaric oxygen therapy and discharged with residual weakness in his right leg.

    The Catastrophic Cognitions Questionnaire-Modified (CCQ-M) is a common instrument for measuring catastrophic thoughts. In some countries, however, CCQ-M still poses concerns following the lack of appropriate validation among their populations. The current study aimed to examine the factor structure of the CCQ-M, the reliability, and the validity in community samples in Malaysia. The Malay version of CCQ-M and additional measures assessing the symptoms and cognitions relevant to anxiety disorders were completed by 682 university students and general community. Exploratory factor analysis revealed a two-factor structure accounting for 62.2% of the total variance. Confirmatory factor analysis confirmed the two-factor model by deleting four items. The Cronbach's alpha coefficients for the total and the two subscales were .94, .90, and .92, respectively. Test-retest reliability analysis was conducted on 82 university students in the interval period of 14 days, and the result was r = .58. Evidence supported the concurrent, convergent, and discriminant validity. In conclusion, the 17-item CCQ-M-Malaysia is a valid and reliable instrument for assessing catastrophic cognitions among Malaysian populations. Copyright © 2015 John Wiley & Sons, Ltd.

    BACKGROUND: The delivery of pelvic floor muscle training (PFMT) through mHealth apps has been shown to produce promising results in improving pelvic floor muscle strength and urinary incontinence (UI). However, there is limited evidence on mHealth apps designed for pregnant women who are at high risk of developing UI. This pilot study aims to evaluate the feasibility of conducting an effectiveness trial for a newly developed PFMT app among pregnant women in Malaysia.

    METHODS: This is a prospective, single-centre, single-blind, randomised controlled pilot feasibility study: The Kegel Exercise Pregnancy Training app (KEPT-app) Trial. Sixty-four incontinent pregnant women who attended one primary care clinic for the antenatal follow-up will be recruited and randomly assigned to either intervention or waitlist control group. The intervention group will receive the intervention, the KEPT-app developed from the Capability, Opportunity, Motivation-Behaviour (COM-B) theory with Persuasive Technology and Technology Acceptance Model.

    DISCUSSION: This study will provide a fine-tuning for our future randomised control study on the recruitment feasibility methods, acceptability, feasibility, and usability of the KEPT-app, and the methods to reduce the retention rates among pregnant women with UI.

    TRIAL REGISTRATION: This study was registered on ClinicalTrials.gov on 19 February 2021 (NCT04762433) and is not yet recruiting.
