    Introduction: The current COVID-19 pandemic has sequelae reverberating around Malaysia, particularly in university students, as Malaysian university students are isolated in their university campuses in semi-quarantine status. This article seeks to review the existing literature on the specialized issue of university student-related psychological sequelae of COVID-19, and seeks to offer some recommendations through the process.
    Methods: Existing literature demonstrates that COVID-19 has affected university students psychosocially, with the rate of anxiety and depression markedly increased. There have been significant alterations of lifestyle related to education, in accordance with the new normal, resulting in isolation and feelings of disengagement with education. Moreover, with the current uncertainties regarding their studies and possible financial depression postpandemic, the future is deeply worrying and will adversely affect their mental health.
    Results: Quantitatively, recent findings indicate 33.3% of the undergraduates in a higher education institution are noted to be in stress. Therefore, multiple interventions have been implemented; a customized ultra-brief psychological module, an online tele psychiatry hotline (COVID Cares) and tele-counselling, which have received universally positive feedback.
    Conclusion: In conclusion, the review demonstrates that undergraduates’ psychological health is an aspect that needs urgent attention as it is not merely limited to the fear of COVID-19, but also related to the social aspects of the pandemic. Multiple interventions have been seen to be efficacious in reducing the psychological sequelae

    Background and Objective: The Fear of COVID-19 Scale (FCV-19S) is a seven-item uni-dimensional scale assessing the severity of COVID-19 concerns. A translation and validation of the FCV-19S in Bahasa Indonesia language was expedited in view of the worrying trends of COVID-19 in Indonesia as well as its psychological squeal.
    Methods:Formal WHO forward and backward translation sequences were applied in translating the English FCV-19S into Bahasa Indonesia. Indonesian university participants were recruited viaconvenience sampling online using snowball methods. The reliability and validity of the Indonesian FCV-19S was psychometrically evaluated by applying confirmatory factor analysis and Rasch analysis in relation to sociodemographic variables and response to the depression, anxiety, and stress components of the Indonesian version of DASS-21. The sample consisted of 434 Indonesian participants.
    Results:The Cronbach α value for the Indonesia FCV-19-I was 0.819 indicated very good internal reliability. The results of the confirmatory factor analysis showed that the uni-dimensional factor structure of the FCV19S fitted well with the data. The FCV-19-I was significantly correlated with anxiety (r=0.705, p

    When x-rays were first discovered, the harmful effects of radiation had to be manifest in the early users before they were known. Today, radiation protection and safety have been established and the effects of radiation, as well as its risks, are known. Even so, medical radiation, in particular the growth in the use of computed tomography (CT), has resulted in soaring radiation doses received by the population in general. Inappropriate use has resulted in overuse, overdose and, perhaps, overdiagnosis, especially when used in screening. In the quest to control and curb the use of procedures involving radiation, however, we must be careful not to provoke a pandemic of irrational fear of radiation. Overreaction to the overuse and overdose of radiation might deter patients from life-saving procedures.

    Successful emotional communication is crucial for social interactions and social relationships. Parkinson's Disease (PD) patients have shown deficits in emotional recognition abilities although the research findings are inconclusive. This paper presents an investigation of six emotions (happiness, sadness, fear, anger, surprise, and disgust) of twenty non-demented (Mini-Mental State Examination score >24) PD patients and twenty Healthy Controls (HCs) using Electroencephalogram (EEG)-based Brain Functional Connectivity (BFC) patterns. The functional connectivity index feature in EEG signals is computed using three different methods: Correlation (COR), Coherence (COH), and Phase Synchronization Index (PSI). Further, a new functional connectivity index feature is proposed using bispectral analysis. The experimental results indicate that the BFC change is significantly different among emotional states of PD patients compared with HC. Also, the emotional connectivity pattern classified using Support Vector Machine (SVM) classifier yielded the highest accuracy for the new bispectral functional connectivity index. The PD patients showed emotional impairments as demonstrated by a poor classification performance. This finding suggests that decrease in the functional connectivity indices during emotional stimulation in PD, indicating functional disconnections between cortical areas.

    While Parkinson's disease (PD) has traditionally been described as a movement disorder, there is growing evidence of disruption in emotion information processing associated with the disease. The aim of this study was to investigate whether there are specific electroencephalographic (EEG) characteristics that discriminate PD patients and normal controls during emotion information processing.

    OBJECTIVE: We evaluated the beliefs, experience and diabetes management strategies of type 2 diabetes mellitus (T2DM) Muslim patients that chose to fast during Ramadan.
    RESEARCH DESIGN AND METHODS: A semistructured focus group interview was conducted with 53 participants with T2DM. Participants were purposefully sampled and asked to share their perspective on Ramadan fasting. All interviews were audio recorded, transcribed verbatim and analyzed thematically.
    RESULTS: Participants reported optimism towards fasting during Ramadan, as they believed that fasting was beneficial to their overall well-being, and a time for family bonding. Most participants made limited attempts to discuss with their doctors on the decision to fast and self-adjusted their medication based on experience and symptoms during this period. They also reported difficulty in managing their diet, due to fear of hypoglycemia and the collective social aspect of fasting.
    CONCLUSION: Muslims are optimistic about their well-being when fasting during Ramadan. Many choose to fulfill their religious obligation despite being discouraged by their doctors. Collaboration with religious authorities should be explored to ensure patients receive adequate education before fasting during Ramadan.

    OBJECTIVES: This paper describes the development and translation of a questionnaire purported to measure (1) the perception of the placement strategy of automated external defibrillator, (2) the perception on the importance of bystander cardiopulmonary resuscitation and automated external defibrillator (3) the perception on the confidence and willingness to apply these two lifesaving interventions as well as (4) the fears and concerns in applying these two interventions. For construct validation, exploratory factor analysis was performed using principal axis factoring and promax oblique rotation and confirmatory factor analysis performed using partial least square.

    RESULTS: Five factors with eigenvalue > 1 were identified. Pattern matrix analysis showed that all items were loaded into the factors with factor loading > 0.4. One item was subsequently removed as Cronbach's alpha > 0.9 which indicates redundancy. Confirmatory factor analysis demonstrated acceptable factor loadings except for one item which was subsequently removed. Internal consistency and discriminant validity was deemed acceptable with no significant cross-loading.

    OBJECTIVES: The COVID-19 pandemic has impacted the mental health of people worldwide. Psychological resilience has been shown to buffer against the threat of the pandemic (i.e., COVID-19 fear) and sustain mental health. The extent to which psychological resilience factors impact mental health maintenance, however, is unclear, given broad differences in infection rates, prevention approaches, government interventions across different cultures and contexts. Our study examines resilience factors and how they protect individuals from COVID-19-related fear and sustain their mental health.

    DATA DESCRIPTION: Data were collected from 1583 (Mage = 32.22, SD = 12.90, Range = 19-82) respondents from Japan, China, the United States, and Malaysia between October to November 2020. We collected data across age and sex, marital status, number of children, and occupations. We also accounted for stay-at-home measures, change in income, COVID-19 infection status, place of residence, and subjective social status in the study. Our variables included mental health-related and resilience constructs, namely (i) fear of COVID-19, (ii) depression, anxiety, and stress; (iii) present, past, and future life satisfaction, (iv) sense of control, (v) positive emotions, (vi) ego-resilience, (vii) grit, (viii) self-compassion, (ix) passion, and (x) relational mobility. All questionnaires were assessed for their suitability across the four countries with the necessary translation checks. Results from this study can be instrumental in examining the impact of multiple resilience factors and their interaction with demographic variables in shaping mental health outcomes.

    BACKGROUND: Numerous studies have explored the association between fear of missing out and mobile phone addiction, but there are different viewpoints and the results are inconsistent. This study intends to estimate the strength of the correlation between fear of missing out and mobile phone addiction in general through a meta-analysis, and to analyze the influencing factors of the inconsistent results of previous studies.

    METHODS: We Searched China National Knowledge Infrastructure Database, Wan fang Database, CQVIP Journal Database、Web of Science Core Collection, Elsevier SD, Springer Online Journals, Medline, EBSCO-ERIC, SAGE Online Journals, PsycINFO, PsycArticles and ProQuest Dissertations and Theses。85 studies (90 independent effect size) were included from 2016 to 2023。The pooled correlation coefficient of the association between fear of missing out and mobile phone addiction was calculated by a random effects model using Comprehensive Meta-Analysis(Version 3.3).

    RESULTS: The main effect analysis revealed a high positive correlation between fear of missing out and mobile phone addiction (r = 0.47, 95%CI [0.44, 0.50]). Furthermore, the measurements of mobile phone addiction moderated the strength of the association between fear of missing out and mobile phone addiction, with the highest correlation measured using MPATS and the lowest correlation measured using MPDQ. The age, gender, year of publication, cultural background, and the measurements of fear of missing out had no significant effect on the correlation between fear of missing out and mobile phone addiction.

    CONCLUSION: The results indicated that fear of missing out was closely related to mobile phone addiction, which complied with the I-PACE model. Psychological services and mental health services should be developed to reduce the emergence of fear of missing out in the digital age and thus alleviate dependence on devices.

    BACKGROUND: Falls in older adults are the result of a complex web of interacting causes, that further results in other physical, emotional, and psychological sequelae. A conceptual framework that represents the reciprocal dynamics of these causal factors can enable clinicians, researchers, and policymakers to clarify goals in falls intervention in older adults.

    METHODS: A Group Model Building (GMB) exercise was conducted with researchers and clinicians from academic units and public healthcare institutes in Singapore. The aim of the exercise was to produce a shared visual representation of the causal structure for falls and engage in discussions on how current and future falls intervention programmes can address falls in the older adults, especially in the Asian context. It was conducted in four steps: 1) Outlining and prioritising desirable patient outcomes, 2) Conceptual model building, 3) Identifying key intervention elements of effective falls intervention programmes, 4) Mapping of interventions to outcomes. This causal loop diagram (CLD) was then used to generate insights into the current understanding of falls causal relationships, current efforts in falls intervention in Singapore, and used to identify gaps in falls research that could be further advanced in future intervention studies.

    RESULTS: Four patient outcomes were identified by the group as key in falls intervention: 1) Falls, 2) Injurious falls, 3) Fear of falling, and 4) Restricted mobility and life space. A CLD of the reciprocal relationships between risk factors and these outcomes are represented in four sub-models: 1) Fear of falling, 2) Injuries associated with falls, 3) Caregiver overprotectiveness, 4) Post-traumatic stress disorder and psychological resilience. Through this GMB exercise, the group gained the following insights: (1) Psychological sequelae of falls is an important falls intervention outcome. (2) The effects of family overprotectiveness, psychological resilience, and PTSD in exacerbating the consequences of falls are not well understood. (3) There is a need to develop multi-component falls interventions to address the multitude of falls and falls related sequelae.

    CONCLUSION: This work illustrates the potential of GMB to promote shared understanding of complex healthcare problems and to provide a roadmap for the development of more effective preventive actions.

    Pathological narcissism or narcissistic personality disorder is commonly characterized by an exaggerated sense of self-importance, condescending attitude, need for excessive admiration, diminished empathy and exploitativeness. In contrast to these overt attributes, there is a different presentation of pathological narcissism which is underrecognized, as one's preoccupation with hypervigilant, self-effacement and proneness to shame in the context of covert grandiose fantasies. This report illustrates a patient who had this subtype of vulnerable narcissism, and how his defence had been activated to preserve own self agency during a session with the doctor by revealing his paraphilic fantasy.

    BACKGROUND: Breast cancer is the most common cancer among women in Malaysia. Barriers for practicing breast self examination (BSE) await exploration.

    OBJECTIVE: To assess the practice of BSE and its correlated factors and particularly barriers amongst urban women in Malaysia.

    METHODS: This cross-sectional study was conducted with 222 Malaysian women using a self-administered questionnaire.

    RESULTS: The mean (SD) age was 28.5 (±9.2) years, 59.0% were university graduates. Of the total, 81.1% were aware of breast cancer and 55% practiced BSE. Amongst 45% of respondents who did not practice BSE, 79.8% did not know how to do it, 60.6% feared being diagnosed with breast cancer, 59.6% were worried about detecting breast cancer, 22% reported that they should not touch their bodies, 44% and 28% reported BSE is embarrassing or unpleasant, 29% time consuming, 22% thought they would never have breast cancer or it is ineffective and finally 20% perceived BSE as unimportant. Logistic regression modeling showed that respondents aged ≥45 years, being Malay, married and having a high education level were more likely to practice BSE (p<0.05).

    CONCLUSION: In this study sample, a significant proportion of respondents was aware of breast cancer but did not practice BSE. Knowledge, psychological, cultural, perception and environmental factors were identified as barriers. BSE practice was associated significantly with socio-demographic factors and socioeconomic status.

    BACKGROUND: Patients with positive immunochemical faecal occult blood test results were found to have poor compliance for a subsequent colonoscopy procedure. This study was conducted to explore patients' perceived deterrence for colonoscopy following a positive stool test.

    METHODS: Using qualitative study method, a phone interview was conducted with 16 patients to elicit their views on the reasons for failure to attend the colonoscopy procedure following a positive stool test. The interviews were audio recorded, transcribed verbatim and translated before proceeded with the data analysis. Content analysis was made on the translated interview, followed by systematic classification of data by major themes.

    RESULTS: Reasons for nonattendance were categorized under five main themes; unnecessary test, fear of the procedure, logistic obstacles (subthemes; time constraint, transportation problem), social influences, and having other health priority. Lacking in information about the procedure during the referral process was identified to cause misperception and unnecessary worry towards colonoscopy. Fear of the procedure was commonly cited by female respondents while logistic issues pertaining to time constraint were raised by working respondents.

    CONCLUSIONS: More effective communication between patients and health care providers are warranted to avoid misconception regarding colonoscopy procedure. Support from primary care doctors, customer-friendly appointment system, use of educational aids and better involvement from family members were among the strategies to increase colonoscopy compliance.

    BACKGROUND: A cancer diagnosis can be psychologically challenging to individuals due to perceptions that the disease is potentially incurable truncating life expectancy. The purpose of the study was to examine the relationships among religious well-being, existential well-being, fear of progression and quality of life in Iranian patients with cancer and to evaluate the potential mediating role of hope on these relationships.

    METHODS: This study with predictive cross-sectional design was done in 2023. Data was gathered from 398 patients with cancer that was selected with accessible sampling method from cancer center of Mazandaran university of medical sciences (Sari, Iran). Study constructs included the religious and existential wellbeing, cancer fear of progression, Snyder Hope, and quality of life. Analysis of a Moment Structures (AMOS) software (v27) was utilized for all study analyses. Covariance based-structural equation modeling (SEM) was used to assess the mediating role of hope.

    RESULTS: The mean age of patients with cancer was 49.14 (SD = 16.16). The results of the direct effect showed a significant positive relationship between religious well-being and hope (B = 0.164, p < .001), and between hope and quality of life (B = 0.212, p < 0.001). Also, significant negative relationship between fear of progression and hope (B = -0.147, p < 0.05) was founded.

    CONCLUSION: A significant positive relationship between hope and quality of life, as well as religious well-being and hope, suggests the influential effects of hope and religious well-being on improving quality of life in patients with cancer. Negative relationships between fear of progression and hope conclude that managing fear of progression may be an important factor in increasing hope and improving quality of life in patients with cancer.

    The objective of this research is to understand the psychological and livelihood-related impacts of coronavirus disease 2019 (COVID-19) on Bangladeshi lower income group people who depend on daily earnings for their living. Following the convenience sampling method, 576 respondents were interviewed for quantitative data and 30 in-depth interviews for qualitative information in several districts of Bangladesh. To 94.1% respondents, livelihood has been affected by the COVID-19 outbreak with an overall score of 3.20 ± 0.77 on a 4-point Likert-type scale. In comparison to unemployed respondents, daily workers have been hardly affected by the COVID-19 outbreak (odds ratio [OR] = 7.957; P < .01), and so they are going outside more frequently in search of jobs (OR = 9.984, P < .01). Due to fear of COVID-19 infection and lack of livelihood means, respondents (76.6%) have been stressed out (overall score 3.19 ± 0.81 on a 4-point Likert-type scale), and those working in industries (OR = 5.818, P < .01), farmers (OR = 3.029, P < .05), and day laborers (OR = 2.651, P < .05) have been highly stressed.

    Emerging research has suggested that appearance-related factors, such as greater appearance orientation, are associated with dating anxiety in emerging adults, but much more could be done to understand mechanistic pathways and potential buffers. Here, we tested a moderated mediation model in which appearance-based rejection sensitivity and social physique anxiety were explored as mediators, and self-compassion was explored as a moderator, of the relationship between appearance orientation and dating anxiety. A total of 501 heterosexual emerging adults (248 women, 253 men) from the UK completed instruments measuring the aforementioned constructs. Relationships among all variables were largely similar across women and men, with only the association between social physique anxiety and appearance-based rejection sensitivity being significantly stronger in women. Mediation analysis in the total sample indicated that both social physique anxiety and appearance-based rejection anxiety were significant mediators. Additionally, we confirmed a serial mediation involving appearance orientation → appearance-based rejection sensitivity → social physique anxiety → dating anxiety. Conversely, self-compassion did not moderate the effects of either social physique anxiety or appearance-based rejection sensitivity on dating anxiety, although greater self-compassion was moderately associated lower dating anxiety. We suggest ways in which existing interventions aimed at reducing dating anxiety could be combined with body image interventions to reduce dating anxiety in heterosocial contexts.

    Dental caries is a major health problem affecting an estimated 90% of school children worldwide. This cross-sectional study aimed to evaluate oral health knowledge, attitude, and practices among secondary school students in Kuching, Sarawak. Data was collected using a pretested questionnaire on 209 randomly selected students from four schools. Results showed no significant differences between the gender and age groups in terms of knowledge level, but significant differences were observed between the schools. The students had positive attitude towards the dental services, but their dental visits were still low due to fear of dental needle and handpieces. Toothbrush and toothpaste were still the most commonly used oral hygiene aids. As compared to parents and friends, dentist was perceived to have more influence on oral hygiene practices among the students. Girls consumed more sweets, snacks and soft drinks than boys. However, girls spent longer time to brush their teeth and brush more frequently. Oral health education should be a life-long practice and incorporated into the school environment with the support of teachers and parents.

    The purpose of this study was to analyze people's attitudes to disasters by investigating how people feel, behave and think during disasters. We focused on disasters induced by humans, such as terrorist attacks. Two types of textual information were collected - from Internet blogs and from research papers. The analysis enabled forecasting of attitudes for the design of proactive disaster advisory scheme. Text was analyzed using a text mining tool, Leximancer. The outcome of this analysis revealed core themes and concepts in the text concerning people's attitudes. The themes and concepts were sorted into three broad categories: Affect, Behaviour, and Cognition (ABC), and the data was visualized in semantic maps. The maps reveal several knowledge pathways of ABC for developing attitudinal ontologies, which describe the relations between affect, behaviour and cognition, and the sequence in which they develop. Clearly, terrorist attacks induced trauma and people became highly vulnerable.

    Advances in characterizing molecular profiles provide valuable insights and opportunities for deciphering the neuropathology of depression. Although abnormal brain-derived neurotrophic factor (BDNF) expression in depression has gained much support from preclinical and clinical research, how it mediates behavioral alterations in the depressed state remains largely obscure. Environmental factors contribute significantly to the onset of depression and produce robust epigenetic changes. Epigenetic regulation of BDNF, as one of the most characterized gene loci in epigenetics, has recently emerged as a target in research on memory and psychiatric disorders. Specifically, epigenetic alterations of BDNF exons are heavily involved in mediating memory functions and antidepressant effects. In this review, we discuss key research on stress-induced depression from both preclinical and clinical studies, which revealed that differential epigenetic regulation of specific BDNF exons is associated with depression pathophysiology. Considering that BDNF has a central role in depression, we argue that memory extinction, an adaptive response to fear exposure, is dependent on BDNF modulation and holds promise as a prospective target for alleviating or treating depression and anxiety disorders.

    INTRODUCTION: During cataract surgery under regional (retrobulbar, peribulbar or sub- Tenon's) or topical anaesthesia, many patients experience a variety of visual sensations in their operated eye intraoperatively. Between 3% and 16.2% of patients are frightened by their intraoperative visual experiences, which may increase the risk of intraoperative complications and affect patients' satisfaction with the surgery. This study aims to determine optometry students' beliefs and knowledge of visual sensations experienced by patients during cataract surgery under regional and topical anaesthesia.

    MATERIALS AND METHODS: A nationwide survey of all Malaysian optometry students using a standardised, self-administered questionnaire.

    RESULTS: All 129 optometry students participated in the survey, giving a 100% response rate. Overall, 26.4% and 29.5% of the students believed that patients undergoing cataract surgery under regional and topical anaesthesia, respectively, may experience no light perception, while 78.3% and 72.9%, respectively, thought that patients would experience light perception. Many respondents also believed that patients might experience a variety of other visual sensations. Of all respondents, 70.5% and 74.4% of students believed that patients undergoing cataract surgery under regional and topical anaesthesia, respectively, may be frightened by their visual experience and 93.0% and 85.3%, respectively, felt that preoperative counselling might help to alleviate this fear.

    CONCLUSION: Many optometry students are aware that patients might encounter a variety of visual sensations during cataract surgery under local anaesthesia. A high proportion of students believe that patients may experience fear as a result of the intraoperative visual sensations and felt that preoperative counselling would be helpful.
