BACKGROUND AND OBJECTIVE
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as the causative agent of COVID-19 has significantly challenged the public health landscape in late 2019. After almost 3 years of the first ever SARS-CoV-2 case, the World Health Organization (WHO) declared the end of this global health emergency in May 2023. Although, despite the subsequent drop of COVID-19 cases, the SARS-CoV-2 infection still exhibited multiple waves of infection, primarily attributed to the appearance of new variants. Five of these variants have been classified as Variants of Concern (VOC): Alpha, Beta, Gamma, Delta, and the most recent, Omicron. Therefore, the development of methods for the timely and accurate detection of viral variants remains fundamental, ensuring an ongoing and effective response to the disease. This study aims to evaluate the feasibility of the application of an in-house approach in genomic surveillance for the detection of SARS-CoV-2 variants using in silico designed primers.
METHODSThe primers used for the study were particularly designed based on conserved regions of certain genes in the virus, targeting distinct mutations found in known variants of SARS-CoV-2. Viral RNA extracts from nasopharyngeal samples (n=14) were subjected to quantitative and qualitative tests (Nanodrop and AGE). Selected samples were then analyzed by RT-PCR and amplicons were submitted for sequencing. Sequence alignment analysis was carried out to identify the prevailing COVID-19 variant present in the sample population.
RESULTSThe study findings demonstrated that the in-house method was able to successfully amplify conserved sequences (spike, envelope, membrane, ORF1ab) and enabled identification of the circulating SARS-CoV-2 variant among the samples. Majority of the samples were identified as Omicron variant. Three out of four designed primers effectively bound into the conserved sequence of target genes present in the sample, revealing the specific SARSCoV-2 variant. The detected mutations characterized for Omicron found in the identified lineages included K417N, S477N, and P681H which were also identified as mutations of interest. Furthermore, identification of the B.1.448 lineage which was not classified in any known variant also provided the potential of the developed in-house method in detecting unknown variants of COVID-19.
CONCLUSIONAmong the five VOCs, Omicron is the most prevalent and dominant variant. The in-house direct PCR product sequencing surveillance (DPPSS) method provided an alternative platform for SAR-CoV-2 variant analysis which is accessible and affordable than the conventional diagnostic surveillance methods and the whole genome sequencing. Further evaluation and improvements on the oligonucleotide primers may offer significant contribution to the development of a specific and direct PCRbased detection of new emerging COVID-19 variants.

OBJECTIVES
The current study aimed to evaluate the impact of an interprofessional simulation-based training program on providers' perception, knowledge, and confidence in proning of pregnant patients with Acute Respiratory Distress Syndrome due to COVID -19 or other causes.
METHODSA total of 124 healthcare workers who took part in the management of patients in COVID wards and ICUs participated in the study. The simulation workshop was conducted on May 2022 and the participants were divided into interprofessional teams. Standardized patients and mannequins were used to simulate patients with ARDS. Standardized checklists for proning were used. The participants were debriefed after. The participants completed pre- and post-simulation questionnaires.
RESULTSAfter the simulation workshop, the participants’ perception on the benefit of prone position in the ventilation of patients with ARDS, level of confidence in handling proning of pregnant patients, comfort in speaking to patient and next of kin regarding prone ventilation, and knowledge on proning significantly improved. Subgroup analysis
showed statistically significant improvements in knowledge scores among registered nurses, resident physicians, and participants with varying degrees of experience managing COVID-19 patients and proning pregnant patients. Majority of participants deemed it was easy to turn patients in the prone position using the supportive pillow as well as expressed confidence in doing the procedure.
Interprofessional simulation-based training of healthcare workers improved providers' knowledge and confidence in proning pregnant patients. Simulation based training also improved the comfort of the healthcare professional in advising the patient and next of kin on the benefits of proning.

OBJECTIVES
A growing body of evidence points to a positive association between periodontitis and
various systemic diseases, including cardiovascular diseases (CVD), hypertension, and rheumatoid arthritis. However,
there is limited data on the prevalence and odds of having systemic conditions among Filipino periodontal patients.
Thus, this study aimed to determine the association of periodontal disease with systemic conditions among Filipino
patients at a university dental clinic.
The periodontal and medical charts of all patients who underwent periodontal consult at a university
dental clinic within two academic years were reviewed. Periodontal diagnoses which had originally been assigned
using the 1999 classification of periodontal diseases were reclassified based on the 2018 European Federation
of Periodontology-American Academy of Periodontology classification. Listed medical conditions in the patients’
charts were self-reported. The prevalence of various systemic conditions in 715 periodontitis cases was compared
to that of 834 control patients without periodontitis. Fisher’s exact test was performed to evaluate the difference
in the prevalence of comorbidities between groups, while adjusted odds ratios (AOR) were computed using logistic
regression analysis, accounting for age, sex, educational attainment, and smoking status.
The prevalence of having at least one systemic condition was significantly higher among periodontitis patients
(44.5%) compared to non-periodontitis patients (36.3%). Compared to controls, a significantly higher number of
periodontitis cases had two systemic comorbidities (P=0.001). The prevalence of hypertension (18.6% versus 5.04%),
CVD including hypertension (20.42% versus 6.95%), arthritis (9.37% versus 3.0%), and diabetes mellitus (5.73% versus
0.84%) were all significantly higher in patients with periodontitis compared to non-periodontitis controls.
The odds of having CVD (AOR=1.81), hypertension (AOR=2.14) and diabetes (AOR=3.05) were higher in periodontitis cases. Meanwhile, the prevalence of asthma (9.23% versus 5.31%), respiratory diseases including asthma (12.95% versus 8.25%), and allergies (18.82% versus 13.71%) were significantly higher in non- periodontitis patients compared to periodontitis cases.
Periodontitis patients were more likely to present with CVD, hypertension, and diabetes mellitus. On the other hand, no association was found between periodontitis and respiratory diseases, as well as between periodontitis and asthma.

BACKGROUND
In response to the need to provide for mental health services to address gender-related concerns in a higher education institute, the University of the Philippines (UP) Manila Center for Gender and Women Studies (CGWS) commissioned a project to formulate a framework for the increasing volume of referrals.
METHODOLOGYA mixed methods study was done in order to gather data to create a responsive and practical mental health care service provision framework with and for service providers and service users in the university. An online survey (N=135), focus group discussion, key informant interviews, and a round table discussion were conducted, with constituents of the university recruited through purposive sampling.
RESULTSA stepped-care model was proposed, consisting of: 1. Preventive Well-Being Resources, 2. Supportive Well-Being Interventions and Initial Screening Resources, 3. Structured Interventions, and 4. Interventions for Severe Mental Health Problems.
CONCLUSIONThe framework formulated in collaboration with service providers and service users in the university addresses the goals of optimizing existing resources and enhancing service provision. Implementation and evaluation of this framework, as well as further information regarding the target population and their use of this model, are proposed avenues for further research.

BACKGROUND
Community Health Workers (CHWs) play a vital role in addressing community healthcare needs, yet little is known about their psychosocial status and job satisfaction. This study aimed to describe the psychosocial status and job satisfaction of CHWs, and examine the factors associated with their job satisfaction.
METHODOLOGYA cross-sectional study was conducted among 440 CHWs aged 25-60 years working in urban and rural areas of Batangas, Philippines. Linear regression models were used to examine the association between psychosocial factors and job satisfaction. Other factors associated with job satisfaction were also examined.
RESULTSDespite 90.0% of CHWs reporting high perceived stress and 52.1% experiencing high depressive symptoms, they demonstrated relatively high job satisfaction (mean [standard deviation]= 80.05 [17.56]; range= 0-100) and high perceived social support (mean [standard deviation]= 25.09 [2.93]; range= 10-30). Among psychosocial factors, only perceived social support was associated with job satisfaction (unstandardized beta [B] 0.93; 95% confidence interval [CI] 0.44, 1.41). Other factors associated with job satisfaction include fixed working hours (B 4.71; 95% CI 0.49, 8.94), work amenities (B 7.37; 95% Cl 0.03, 14.72), ≥21 years of work experience (B 5.64; 95% CI 0.35, 10.93), and working in rural areas (B 5.88; 95% CI 2.77, 8.99).
CONCLUSIONPsychological factors such as perceived stress and depressive symptoms were not found to be associated with job satisfaction among CHWs. However, factors such as greater perceived social support, fixed working hours, work amenities, longer work experience, and working in rural areas were identified as contributors to higher levels of job satisfaction among CHWs.

INTRODUCTION:
Impostor phenomenon (IP) is a set of feelings encountered by individuals of being incompetent, despite experiencing successes. IP affects not only individuals on a personal level, but also organisations where the leadership diversity decreases due to employees' self-doubt. We aim to investigate the prevalence of IP and burnout among employees in the National University Health System (NUHS).
METHODS:
All permanently employed full-time NUHS employees aged 21 years and above were invited to participate in this self-administered cross-sectional study between April 2021 and August 2021. Mass emails with the embedded study link were sent every 2-3 weeks to the employees' corporate email accounts.
RESULTS:
In our study, 61% of our study respondents reported having IP experiences and 97% reported having burnout. The associations of IP with ethnicity and age group were significant. Post hoc tests, however, showed that the association was statistically significant only in the 21-29 years age group.
CONCLUSION
We found that there was no statistical significance between gender and the Maslach Burnout Inventory (MBI) profile types. However, we found that IP was significantly associated with individuals in the 21-29 years age group. This could be because younger individuals who just entered workforce may feel uncomfortable with their newfound independence and responsibility. Workplace support, such as workshops, and emotional support were found to be useful in helping individuals cope with IP. Future studies could be done post coronavirus disease 2019 (COVID-19) pandemic among healthcare workers to have a larger sample size to determine true IP and burnout prevalence.

INTRODUCTION:
A successful vaccination programme forms the cornerstone of controlling coronavirus disease 2019 (COVID-19). The unprecedented speed of COVID-19 vaccine development and lack of long-term data have raised fears regarding its safety and efficacy. Vaccine hesitancy can undermine the uptake, and hence success of the vaccination programme. Given the high complication rates of COVID-19 infections in kidney transplant recipients, it is particularly important to identify and address vaccine hesitancy in this population.
METHODS:
We conducted a cross-sectional survey among kidney transplant recipients attending transplant clinic between 5 April and 5 May 2021. The survey assessed attitudes towards COVID-19, willingness/hesitancy towards COVID-19 vaccination, vaccination concerns and prompts to vaccination. This was scored on a Likert scale with scores ranging from 'strongly disagree' - 1 point to 'strongly agree' - 5 points.
RESULTS:
One hundred and one completed responses were captured. Of these, 86% respondents reported to agree or strongly agree to vaccination. This was despite significant concerns of allograft rejection (mean score 4.12, standard deviation [SD] 0.97) and decreased immunosuppressant efficacy (mean score 4.14, SD 0.96) with vaccination. Multivariable model showed a positive association with transplant vintage of ≥ 5 years (median 2.41), lower educational levels of secondary school or less (median 5.82) and healthcare provider advocacy (median 1.88) in predicting vaccine acceptance.
CONCLUSIONS
Vaccine acceptance rate was high among kidney transplant recipients. Vaccine hesitancy remains a concern in those with a transplant vintage of less than 5 years and those with tertiary educational level. Healthcare provider advocacy is important in improving vaccine acceptance rates.

BACKGROUND:
Effective interventions during the coronavirus disease 2019 (COVID-19) pandemic require an understanding of patients' knowledge and perceptions that influence their behaviour. Our study assessed knowledge of COVID-19 among kidney transplant recipients and donors, hitherto unevaluated.
METHODS:
We conducted a cross-sectional survey among 325 kidney transplant recipients and 172 donors between 1 May 2020 and 30 June 2020. The survey questionnaire assessed knowledge levels of COVID-19, sociodemographic data, health status, psychosocial impact of COVID-19 and precautionary behaviours during the pandemic.
RESULTS:
The mean COVID-19 knowledge score of the study population was 7.5 (standard deviation: 2.2) out of 10. The mean score was significantly higher among kidney recipients compared to kidney donors (7.9 [1.9] vs. 6.7 [2.6]; P <0.001). Younger age (21-49 vs. ≥50 years) and higher education (diploma and higher vs. secondary and lower) were associated with significantly higher knowledge scores in donors, but not among recipients ( P -interactions ≤0.01). In both kidney recipients and donors, financial concerns and/or social isolation were associated with lower knowledge levels.
CONCLUSIONS
Concerted efforts are needed to improve COVID-19 knowledge in kidney transplant recipients and donors, particularly older donors, donors with lower education and patients with financial concerns or feelings of social isolation. Intensive patient education may mitigate the impact of education levels on COVID-19 knowledge levels.

INTRODUCTION:
In the early phase of the coronavirus disease 2019 (COVID-19) pandemic, children with COVID-19 in Singapore required hospital isolation. We aimed to explore the psychological experiences of children and their caregivers isolated in a tertiary university hospital due to COVID-19.
METHODS:
A prospective mixed-methods design was used to evaluate the psychological status of hospitalised family units with one or more children aged <18 years who had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patient medical records were reviewed for demographic and clinical information. Parents and children ≥7 years of age underwent a psychologist-administered telephone-based interview. Self-reported, age-appropriate instruments, Short Mood and Feelings Questionnaire, and Screen for Adult/Child Anxiety-Related Disorders, were used to assess anxiety and depression, respectively. Participants were also interviewed qualitatively.
RESULTS:
Fifteen family units were hospitalised between March 2020 and May 2020. Of these, 13 (73%) family units were recruited. The median age of the children and median hospitalisation duration were 57 months and 21 days, respectively. Median number of COVID-19 polymerase chain reaction swabs performed for each child was eight. All children had asymptomatic to mild SARS-CoV-2 disease. The criteria indicative of anxiety disorder were met by 40% of adults and 80% of children, while the criteria indicative of separation anxiety were met by 60% of parents and 100% of children. One child met the criteria indicative of depression. Uncertainty, separation, prolonged hospitalisation and frequent swabs caused significant reported anxiety.
CONCLUSIONS
Families, especially children, had heightened anxiety while in hospital isolation. Therefore, home-based recovery from COVID-19 and psychological support for children and their families, with focus on early recognition of anxiety disorders, are recommended. We support review of paediatric isolation policy as the pandemic evolves.

Singapore medical journal 2025;66(6):314-320
INTRODUCTION:
The survival rate for childhood cancer has increased with advances in medical care. Along with this comes the growing burden of long-term side effects of cancer treatment and cancer survivorship. Childhood cancer survivors are more likely to be sedentary and have a lower quality of life. Physical activity (PA) can promote health and well-being in childhood cancer survivors, but few studies have explored the role of parents of childhood cancer survivors (PCCS) in promoting PA. This qualitative study aims to explore the perceptions of PCCS in Singapore and the role they may have with regard to PA.
METHODS:
Participants were recruited through a local charity via email, social media and posters. One-hour semi-structured interviews were conducted online with seven parents. With consent, the interviews were recorded, transcribed verbatim and analysed using thematic analysis.
RESULTS:
Our study discussed thematically parents' accounts on (1) the barriers and enablers of PA and (2) the complications of cancer that potentially affect the levels of PA in childhood cancer survivors. Parents reported that childhood cancer negatively affects the quality of life and participation in PA. The determinants of participation in PA were multifaceted, and socioecological and health belief models were used to demonstrate how these factors were interlinked.
CONCLUSION
Participation in PA is influenced at an individual, family, community and societal level. The improved understanding facilitated by this research can be used to shape paediatric cancer care practices in Singapore and guide institutional or national policy interventions.
