AB074. Propensity-score matched analysis to evaluate the safety and utility of intraoperative cell-salvaged autologous blood transfusion in metastatic spine tumour surgery.

BACKGROUND: Blood loss is an important consideration in metastatic spine tumour surgery (MSTS). Allogeneic blood transfusion (ABT) is the current standard of blood replenishment for MSTS despite known complications. Salvaged blood transfusion (SBT) through intraoperative cell salvage addresses the majority of complications related to ABT. However, the use of SBT in MSTS still remains controversial. We aim to conduct a prospective propensity-score (PS) matched analysis to evaluate the long-term clinical outcomes of intraoperative cell salvage (IOCS) in MSTS. METHODS: Our study included 98 patients who underwent MSTS from 2014-2017. A PS matched cohort was created using the relevant and available predictors of treatment assignment and outcomes of interest. Clinical outcomes consisting of overall survival (OS), as well tumour progression (TP) that was evaluated using RECIST (v1.1) were compared in the matched cohort. RESULTS: Our study had a total of 98 patients with a mean age of 60 years old. A total of 33 patients received SBT. Overall median blood loss was 600 mL [interquartile range (IQR): 300-1,000 mL] and overall median blood transfusion (BT) was 620 mL (IQR: 110-1,600 mL). Group PS matching included 30 patients who received ABT and 28 patients who received SBT. There was also no significant difference between the OS of patients who underwent ABT or SBT (P=0.19). SBT did not show any significant increase in 4-year tumour progression [PS matched hazard ratio (HR) 3.659; 95% confidence interval (CI): 0.346-38.7; P=0.28]. CONCLUSIONS: SBT has been shown to have similar clinical outcomes to that of ABT in patients undergoing MSTS, with potential benefits of avoiding complications and costs of ABT. This will be the first long-term PS matched analysis to report on the clinical outcomes of SBT and affirms the clinical role of SBT in MSTS today.

AB078. Patterns of treatment delay in patients with symptomatic metastatic epidural spinal cord compression.

BACKGROUND: Delayed treatment in symptomatic metastatic epidural spinal cord compression (MESCC) is significantly associated with poorer functional outcomes. In this study, we aim to identify the patterns of treatment delay in patients and factors predictive of postoperative ambulatory function. METHODS: Retrospective review of patients with symptomatic MESCC treated surgically between January 2015 and January 2022. MESCC symptoms were categorized into symptoms suggesting cord compression requiring immediate referral and symptoms suggestive of spinal metastases. Multivariate analysis was performed to identify factors predictive of postoperative ambulatory function. Delays in treatment were identified and categorized into patient delay (onset of symptoms till initial medical consultation), diagnostic delay (medical consultation till radiological diagnosis of MESCC), referral delay (from diagnosis till spine surgeon review) and surgical delay (from spine surgeon review till surgery) and compared between patients. RESULTS: One hundred and seventy-eight patients were identified. In this cohort 92 (52.0%) patients were able to ambulate independently, and 86 (48.3%) patients were non independent. One hundred and thirty-nine (78.1%) of patients had symptoms of cord compression and 93 (52.3%) had neurological deficits on presentation. On multivariate analysis, pre-operative neurological deficits (P=0.01) and symptoms of cord compression (P=0.01) were significantly associated with post-operative ambulatory function. Mean total delay was 66 days, patient delay was 41 days, diagnostic delay was 16 days, referral delay was 3 days and surgical delay was 6 days. In patients with neurological deficits, there was a significant decrease in all forms of treatment delay (P<0.05). There was no significant decrease in patient delay, diagnostic delay and referral delay in patients with symptoms of cord compression. CONCLUSIONS: Both patients and physicians understand the need for urgent surgical treatment of MESCC with neurological deficits, however there is still a need for increased education and recognition of the symptoms of MESCC.

AB077. An evaluation of prognostic scoring systems for survival in a surgically treated cohort of 318 metastatic spine tumour surgery patients.

BACKGROUND: Survival prognostication plays a key role in the decision-making process for the surgical treatment of patients with spinal metastases. In the past traditional scoring systems such as the modified Tokuhashi and Tomita scoring systems have been used extensively, however in recent years their accuracy has been called into question. This has led to the development of machine learning algorithms to predict survival. In this study, we aim to compare the accuracy of prognostic scoring systems in a surgically treated cohort of patients. METHODS: This is a retrospective review of 318 surgically treated spinal metastases patients between 2009 and 2021. The primary outcome measured was survival from the time of diagnosis. Predicted survival at 3 months, 6 months and 1 year based on the prognostic scoring system was compared to actual survival. Predictive values of each scoring system were measured via area under receiver operating characteristic curves (AUROC). The following scoring systems were compared, Modified Tokuhashi (MT), Tomita (T), Modified Bauer (MB), Van Den Linden (VDL), Oswestry (O), New England Spinal Metastases score (NESMS), Global Spine Study Tumor Group (GSTSG) and Skeletal Oncology Research Group (SORG) scoring systems. RESULTS: For predicting 3 months survival, the GSTSG 0.980 (0.949-1.0) and NESM 0.980 (0.949-1.0) had outstanding predictive value, while the SORG 0.837 (0.751-0.923) and O 0.837 (0.775-0.900) had excellent predictive value. While for 6 months survival, only the O 0.819 (0.758-0.880) had excellent predictive value and the GSTSG 0.791(0.725-0.857) had acceptable predictive value. For 1 year survival, the NESM 0.871 (0.822-0.919) had excellent predictive value and the O 0.722 (0.657-0.786) had acceptable predictive value. The MT, T and MB scores had an area under the curve (AUC) of <0.5 for 3-month, 6-month and 1-year survival. CONCLUSIONS: Increasingly, traditional scoring systems such as the MT, T and MB scoring systems have become less predictive. While newer scoring systems such as the GSTSG, NESM and SORG have outstanding to excellent predictive value, there is no one survival scoring system that is able to accurately prognosticate survival at all 3 time points. A multidisciplinary, personalised approach to survival prognostication is needed.

Development of the Paternal Involvement in Early Infancy Scale (PEACE) for fathers in Singapore.

OBJECTIVES: To develop and validate a psychometrically sound self-reported Paternal involvement in Early InfAnCy ScalE (PEACE) for Asian fathers with infants aged 0-12 months old. METHODS: This study comprised of three phases: (1) Pilot test among 100 fathers, (2) Exploring and confirming the PEACE's multidimensional structure using exploratory factor analysis (EFA) (n = 200 fathers) and confirmatory factor analysis (CFA) (n = 200 fathers), and (3) Assessing one-month test-retest reliability of PEACE among 30 fathers. Data was collected from August 2022 to August 2023. The EFA was conducted using principal axis factoring and varimax rotation. The CFA confirmed the factor structure via goodness-of-fit statistics. To assess the PEACE's concurrent validity, paternal involvement was measured using a previously validated paternal involvement scale. Convergent validity was established by examining correlations between PEACE and theoretically related measures of parenting self-efficacy, parent-child bonding, parenting satisfaction, and depression. Test-retest reliability was examined using the intra-class correlation coefficient. RESULTS: The EFA and CFA results supported the five-factor 25-item PEACE. The five subscales were: i) Providing Tangible Support, ii) Meeting Basic Needs, iii) Bonding with Baby, iv) Decision-Making for Baby, and v) Sense of Responsibility and Accomplishment. All subscales reported good internal consistency and weak to moderate one-month test-retest reliability. Correlation coefficients between the PEACE and other scales supported the concurrent and convergent validity of the PEACE. CONCLUSION: This study provided sufficient evidence to establish the initial reliability and validity of the five-factor 25-item PEACE. IMPLICATIONS TO PRACTICE: The PEACE could be used to quantitatively assess paternal involvement in infant care.

Motoric cognitive risk syndrome as a predictive factor of cognitive impairment and dementia - A systematic review and meta-analysis.

BACKGROUND: Motoric cognitive risk syndrome (MCR) is defined as the presence of slow gait-speed and subjective cognitive decline in older individuals without mobility disability or dementia. While some studies suggest that MCR is a pre-dementia syndrome and may help predict the risk of cognitive impairment and dementia, not all studies concur. The objective of this study is to comprehensively summarize and synthesize evidence to assess the association between MCR and cognitive impairment and dementia. METHODS: Following a pre-specified protocol, two authors systematically searched PubMed, Embase, and The Cochrane Library from inception to 19 August 2024 for observational or randomized studies pertaining to the association between MCR and cognitive impairment and dementia. We favoured maximally adjusted hazards and odds ratios to determine the longitudinal and cross-sectional risk of cognitive impairment and dementia. We investigated for potential sources of heterogeneity and also conducted sensitivity and subgroup analyses by continent and the type of cognitive outcome. The quality of evidence was assessed using the Newcastle-Ottawa Scale (NOS) and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. RESULTS: We included 20 studies comprising a combined cohort of 1206,782 participants, of which 17 studies were included in the quantitative analysis. The pooled analysis outlined that individuals with MCR exhibited 2.20-fold higher risk of cognitive impairment and dementia, compared to controls (RR=2.20; 95 %CI=1.91-2.53). These findings remained robust across all subgroup analyses, sensitivity analyses and assessments of publication bias. CONCLUSION: MCR may be considered a predictive factor for long-term cognitive impairment and dementia. This should be taken into consideration when clinically evaluating the risk of cognitive impairment and dementia but further research is required to lend greater clarity to this association.

Effectiveness of peer support interventions in improving mothers' psychosocial well-being during the perinatal period: A systematic review and meta-analysis.

BACKGROUND: Many mothers experience poor psychological outcomes during their perinatal period. The presence of depression and anxiety has a significant adverse impact on the mother's health and the infant's development. AIM: This review aimed to examine the effectiveness of peer support interventions in improving depression, anxiety, and perceived social support among mothers during the perinatal period. METHODS: This study was a systematic review and meta-analysis of randomized controlled trials. The reporting of this review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020. Cochrane's Risk of Bias Tool for randomized controlled trials was used to examine the methodological quality of the included studies. The certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. A comprehensive search was conducted from inception till May 2024 across seven databases: Pubmed, Scopus, CINAHL, Web of Science, ProQuest, PsycINFO, and Embase. RESULTS: The results of the meta-analysis of the 12 included studies showed that peer support interventions could reduce depression and anxiety levels but not perceived social support levels. Sub-group analyses based on the mode of intervention delivery showed significant reductions on depression levels in online and face-to-face groups but not telephone call groups. Follow-up data analyses showed that peer support interventions could improve depression, anxiety, and perceived social support across a duration of 1-6 months post-intervention. LINKING EVIDENCE TO ACTION: This review provides a deeper understanding of the effect of peer support interventions on mothers in the perinatal period. This can have a positive impact on current knowledge aimed at improving the well-being of mothers and thus, their infants, partners, and entire family unit. Findings showed that peer support interventions can positively improve psychological well-being of mothers in the perinatal period in the short and long term. Peer support can ultimately be considered as a standardized part of perinatal care. Future recommendations include implementing a combination of face-to-face and online approaches to peer support interventions delivered with both individual and group components.

Glutathione-S-Transferase Theta 2 (GSTT2) Modulates the Response to Bacillus Calmette-Guérin Immunotherapy in Bladder Cancer Patients.

Glutathione-S-transferases (GST) enzymes detoxify xenobiotics and are implicated in response to anticancer therapy. This study evaluated the association of GST theta 1 (GSTT1), GSTT2, and GSTT2B with Mycobacterium bovis Bacillus Calmette-Guérin (BCG) response in non-muscle-invasive bladder cancer treatment. In vitro assessments of GSTT2 knockout (KO) effects were performed using cell lines and dendritic cells (DCs) from GSTT2KO mice. Deletion of GSTT2B, GSTT1, and single-nucleotide polymorphisms in the promoter region of GSTT2 was analysed in patients (n = 205) and healthy controls (n = 150). Silencing GSTT2 expression in MGH cells (GSTT2BFL/FL) resulted in increased BCG survival (p < 0.05) and decreased cellular reactive oxygen species. In our population, there are 24.2% with GSTT2BDel/Del and 24.5% with GSTT2BFL/FL. With ≤ 8 instillations of BCG therapy (n = 51), 12.5% of GSTT2BDel/Del and 53.8% of GSTT2BFL/FL patients had a recurrence (p = 0.041). With ≥9 instillations (n = 153), the disease recurred in 45.5% of GSTT2BDel/Del and 50% of GSTT2BFL/FL. GSTT2FL/FL patients had an increased likelihood of recurrence post-BCG therapy (HR 5.5 [1.87-16.69] p < 0.002). DCs from GSTT2KO mice produced three-fold more IL6 than wild-type DCs, indicating a robust inflammatory response. To summarise, GSTT2BDel/Del patients respond better to less BCG therapy and could be candidates for a reduced surveillance regimen.

Screen time and social-emotional skills in preschoolers with developmental, behavioural or emotional issues in Singapore.

Introduction: This study aimed to determine patterns of screen viewing time (SVT) in preschool children with developmental, behavioural or emotional (DBE) issues, and to identify its relationship with social-emotional development. Method: This cross-sectional study involved children aged 0-5 years who were referred to a developmental paediatric clinic for DBE issues. Parents completed a screen time questionnaire, and the Devereux Early Childhood Assessment-Clinical (DECA-C) question-naire which assessed the social-emotional competence of the children. Data were analysed using logistic regression, correlational analyses and tests of comparison. Results: Among 225 children (mean age: 32.4 months), mean daily SVT was 138 minutes. More than half (51.1%) of the children had clinical features of language delay, while 26.6% had features suggestive of autism spectrum disorder. Screen time was first introduced at a mean age of 13.8 months, with 32.4% of children previously experiencing higher SVT. Compared to SVT introduction after 1 year of age, SVT in the first 12 months was primarily to facilitate feeding (P<0.05). Children with higher past SVT had poorer attention, more aggression, and increased behavioural concerns. Children with DBE issues have significantly more screen time than same-aged peers. Conclusion: Children with DBE issues are exposed to SVT at a very young age and have significantly more screen time than their peers. It is crucial to guide parents to reduce SVT in early childhood, particularly around mealtimes.

Nurturing networks: A prospective longitudinal study of factors influencing help-seeking behaviours among mothers from low socioeconomic status.

AIM: To explore the factors influencing help-seeking behaviours amongst mothers with low socioeconomic status at pregnancy, 1 month postpartum and 3 months postpartum. METHODS: A prospective cohort study was conducted from September 2022 to August 2023. A total of 209 mothers aged 21 years and above, with low socioeconomic status and irrespective of parity, were recruited from a local hospital using convenience sampling. Self-administered questionnaires were used to collect data at (1) third trimester of pregnancy, (2) 1 month postpartum and (3) 3 months postpartum. Multiple regression analysis was used to identify significant factors influencing help-seeking behaviour at 3 months postpartum. Sub-analyses were conducted between primiparous mothers and multiparous mothers. General linear model repeated measures were used to identify longitudinal trends in outcomes of help-seeking behaviour. RESULTS: Help-seeking behaviour at pregnancy and 1 month postpartum, sources of social support at 3 months postpartum, birth order of the child, attendance of antenatal classes, paternal involvement in feeding and changing diapers and mode of delivery significantly predicted mothers' help-seeking behaviour at 3 months postpartum. Amongst primiparous mothers, help-seeking behaviour at pregnancy at 1 month, social support at 3 months postpartum, employment in part-time jobs and exclusively breastfeeding their infant were significant factors in influencing their help-seeking behaviours at 3 months postpartum. For multiparous mothers, help-seeking behaviour at pregnancy and 1 month postpartum, number of hours of antenatal class attended, Malay ethnicity, educational background, parental satisfaction at 3 months postpartum and infant bonding at both time points were significant factors influencing their help-seeking behaviours at 3 months postpartum. CONCLUSION: Primiparous mothers with low socioeconomic status who underwent caesarean section exhibited less help-seeking behaviours. Attendance of antenatal classes and greater paternal involvement in infant care encouraged mothers with low socioeconomic status to help-seeking behaviours. A tailored approach is needed to support mothers with low socioeconomic status by providing additional support in improving the accessibility of antenatal classes and involving fathers in infant care. IMPACT: What Problem Did the Study Address? Mothers with low socioeconomic status tend to exhibit lower help-seeking behaviours due to limited support and access to care services. What Were the Main Findings? First-time mothers who underwent caesarean section, did not attend antenatal classes, and had husbands uninvolved in feeding and diaper changing were significantly less likely to seek help in the third month postpartum. One and 3 months postpartum are crucial time points when mothers with low socioeconomic status could benefit from additional support. Hospitals should explore online informational resources, forums, teleconsultations and virtual antenatal classes as possible alternative options to improve accessibility for mothers with low socioeconomic status. Where and on Whom Will the Research Have an Impact? Mothers with low socioeconomic status and healthcare providers of mothers with low socioeconomic status will benefit from the findings of this research. This study was conducted within the Singapore context. Findings could be generalizable to other cultural contexts with similar multi-ethnic populations. REPORTING METHOD: STROBE checklist. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Symptoms and coronary risk factors predictive of adverse cardiac events in chest pain patients in an Asian emergency department: the need for a local prediction score.

INTRODUCTION: Clinical assessment is pivotal in diagnosing acute coronary syndrome. Our study aimed to identify clinical characteristics predictive of major adverse cardiac events (MACE) in an Asian population and to derive a risk score for MACE. METHODS: Patients presenting to the emergency department (ED) with chest pain and non-diagnostic 12-lead electrocardiograms were recruited. Clinical history was recorded in a predesigned template. Random glucose and direct low-density lipoprotein measurements were taken, in addition to serial troponin. We derived the age, coronary risk factors (CRF), sex and symptoms (ACSS) risk score based on multivariate analysis results, considering age, CRF, sex and symptoms and classifying patients into very low, low, moderate and high risk for MACE. Comparison was made with the ED Assessment of Chest Pain Score (EDACS) and the history, electrocardiogram, age, risk factors, troponin (HEART) score. We also modified the HEART score with the CRF that we had identified. The outcomes were 30-day and 1-year MACE. RESULTS: There were a total of 1689 patients, with 172 (10.2%) and 200 (11.8%) having 30-day and 1-year MACE, respectively. Symptoms predictive of MACE included central chest pain, radiation to the jaw/neck, associated diaphoresis, and symptoms aggravated by exertion and relieved by glyceryl trinitrate. The ACSS score had an area under the curve of 0.769 (95% confidence interval [CI]: 0.735-0.803) and 0.760 (95% CI: 0.727-0.793) for 30-day and 1-year MACE, respectively, outperforming EDACS. Those in the very-low-risk and low-risk groups had <1% risk of 30-day MACE. CONCLUSION: The ACSS risk score shows potential for use in the local ED or primary care setting, potentially reducing unnecessary cardiac investigations and admission.

DUETS for Light's in separating exudate from transudate.

BACKGROUND: Fifty years since its inception, Light's criteria have aided in classifying pleural effusions (PEs) as exudates if 1 or more criteria are met. Thoracic ultrasound (US) emerges as a non-invasive technique for point of care use especially if pleural procedures are contemplated. OBJECTIVE: We aimed to develop a score based on radiological and US features that could separate exudates from transudates without serum and pleural fluid biochemical tests necessary for Light's criteria. METHODS: A prospective review of consecutive patients with PE who underwent thoracocentesis was performed. CXRs were evaluated for laterality followed by US for echogenicity, pleural nodularity, thickening and septations. PE was classified as exudate or transudate according to Light's criteria and corroborated with albumin gradient. A score combining radiological and US features was developed. RESULTS: We recruited 201 patients with PE requiring thoracocentesis. Mean age was 64 years, 51% were females, 164 (81.6%) were exudates, and 37 (18.4%) were transudates. Assigning 1-point for Diaphragmatic nodularity, Unilateral, Echogenicity, Pleural Thickening and Septations, DUETS ranged from 1 to 5. DUETS ≥2 indicated high likelihood for exudate (PPV 98.8%, NPV 100%) with 1% misclassification versus 6.9% using Light's criteria (p < 0.001). CONCLUSION: DUETS separated exudates from transudates with good accuracy, and could obviate paired serum and pleural fluid tests necessary for Light's criteria computation. Our study reflected real world practice where DUETS performed better than Light's criteria for PE that arose from more than one disease processes, and in the evaluation of patients with PE who have received diuretics.

Ontological coaching among nursing undergraduates: a pilot randomized controlled (OCEAN) trial.

To develop and assess the preliminary effectiveness of Ontological Coaching Intervention for nursing undergraduates. Design: A pilot randomized controlled trial with a two-group pre-test and post-test followed by process-evaluation qualitative interviews. An Ontological Coaching Intervention was developed through an integration of prior literature and the collective the research team's experience, consisting of 4-6 sessions over 6-months, each lasting 30-60 minutes. Sessions encompassed exploring ontological coaching concepts, empowering nursing undergraduates to choose topics, and tailoring sessions to individual needs. Sixty undergraduates were recruited; ten were excluded for not completing the baseline questionnaires. Twenty-one nursing undergraduates were randomly assigned to the intervention group and twenty-nine undergraduates to the control group (standard academic support only). Primary (psychological well-being) and secondary (social support quantity and satisfaction, goal-setting, resilience) outcomes were measured at baseline, 3-months, and 6-months. Semi-structured interviews captured post-intervention experiences. Between-group analyses revealed a significant difference in goal-setting scores at 3-months (U = 325.5, p = 0.013), favoring the intervention group (median = 70.50, IQR = 64.25, 76.75). At 6-months, a significant difference in social support satisfaction scores (U = 114.5, p = 0.028) was found between the intervention (median = 33.00, IQR = 29.50, 35.25) and control (median = 30.00, IQR = 30.00, 35.00) groups. However, no significant between-group differences were noted in other outcome measures. Significant within-group differences were found in goal-setting scores at 3- and 6-months in the intervention group and social support quantity scores at 3- and 6-months in the control group. However, no significant within-group differences were noted in other outcome measures. Three themes were identified: Enhanced Holistic Development, Keys to Successful Coaching, and Future Directions for Successful Coaching. There is urgent need to advance research on Ontological Coaching Intervention, particularly, enhancing study rigor, broadening examinations to diverse healthcare student populations and cultural contexts, and addressing identified limitations.

Health practices, behaviours and quality of life of low-income preschoolers: A community-based cross-sectional comparison study in Singapore.

Introduction: Children from low-income (LI) families often suffer from poor health, with sub-optimal health practices. This cross-sectional study examined the differences in health habits and health-related quality of life (HRQoL) of LI preschool children compared to non-low-income preschool peers (PPG). Method: Using data from the social-health Circle of Care-Health Development Screening Programme (CoC-HDSP) in Singapore, 118 LI children and 304 PPG children aged 18 months to 6 years old and their families were recruited from 13 government-funded preschools. Health practices examined included screen time habits, sleep, nutrition, dental health and the children's HRQoL using PedsQL 4.0 Generic Core Scales. Results: Majority of the children were aged 4-6 years in kindergarten 1 and 2. There were more Malay children in the LI than the PPG (61.9% versus [vs] 29.3%, P<0.001). Low-income children were more likely to have lower-educated parents (P<0.001). The completed vaccination rate in the LI group was lower than those in PPG (84.7% vs 98.0%, P<0.001). More in the LI group utilised emergency services for acute illnesses (P<0.05). Fewer LI children had ever visited a dentist (47.4% vs 75.4%, P<0.001), and more LI children consumed sweetened drinks daily (33.3% vs 8.6%, P<0.001). The LI group reported poorer-quality sleep (48.3% vs 27.2%, P<0.001), though both groups exceeded the daily recommended screen viewing duration. The LI group scored higher in the social (mean 92.4±12.2 vs 84.3±15.3, P<0.001) and emotional (mean 85.2±15.1 vs 76.6±17.3, P<0.001) domains of the PedsQL 4.0 when compared to PPG. Conclusion: Low-income children have poorer health practices, receive less preventive paediatric care, and utilise more emergency services for acute illnesses. These findings are important for developing interventions that work towards improving the health of LI children.

Effects of Parental Predictors on Postpartum Depression.

BACKGROUND: Postpartum depression (PPD) is highly prevalent and plagues a significant proportion of parents. Postpartum depression also exerts various negative consequences on infant development and parent-infant relationships. Social support is identified as an important factor influencing many parental predictors, and may affect the development of PPD. OBJECTIVE: This study aimed to investigate how perceived social support can indirectly influence PPD symptoms in parents at 6 months postpartum by influencing postpartum anxiety, parental satisfaction, and parental self-efficacy (PSE). METHODS: A secondary analysis of data from a randomized controlled trial was used with a cross-sectional exploratory design. A total of 400 Singaporean parents (200 couples) were included, and structural equation modeling was used to analyze the relationships between PPD and potential predictors. RESULTS: Findings revealed a less adequate fit between the hypothesized model and the data collected. Social support was found to be a significant predictor of postpartum anxiety, PSE, and parental satisfaction. Postpartum anxiety was a significant predictor of PPD, but PSE and parental satisfaction were not. CONCLUSION: This study provides an overview of how different parental predictors may be associated with PPD among Asian parents. Postpartum anxiety significantly predicted PPD, but social support had negative effects on postpartum anxiety, parenting satisfaction, and PSE. The findings provide further insight into how parents at risk of PPD can be identified and demonstrated how social support might negatively impact parental outcomes. More qualitative research with Asian parents is needed to further explain these findings and inform the development of future interventions.

Parents' Perceptions of Their Parenting Journeys and a Mobile App Intervention (Parentbot-A Digital Healthcare Assistant): Qualitative Process Evaluation.

BACKGROUND: Parents experience many challenges during the perinatal period. Mobile app-based interventions and chatbots show promise in delivering health care support for parents during the perinatal period. OBJECTIVE: This descriptive qualitative process evaluation study aims to explore the perinatal experiences of parents in Singapore, as well as examine the user experiences of the mobile app-based intervention with an in-built chatbot titled Parentbot-a Digital Healthcare Assistant (PDA). METHODS: A total of 20 heterosexual English-speaking parents were recruited via purposive sampling from a single tertiary hospital in Singapore. The parents (control group: 10/20, 50%; intervention group: 10/20, 50%) were also part of an ongoing randomized trial between November 2022 and August 2023 that aimed to evaluate the effectiveness of the PDA in improving parenting outcomes. Semistructured one-to-one interviews were conducted via Zoom from February to June 2023. All interviews were conducted in English, audio recorded, and transcribed verbatim. Data analysis was guided by the thematic analysis framework. The COREQ (Consolidated Criteria for Reporting Qualitative Research) checklist was used to guide the reporting of data. RESULTS: Three themes with 10 subthemes describing parents' perceptions of their parenting journeys and their experiences with the PDA were identified. The main themes were (1) new babies, new troubles, and new wonders; (2) support system for the parents; and (3) reshaping perinatal support for future parents. CONCLUSIONS: Overall, the PDA provided parents with informational, socioemotional, and psychological support and could be used to supplement the perinatal care provided for future parents. To optimize users' experience with the PDA, the intervention could be equipped with a more sophisticated chatbot, equipped with more gamification features, and programmed to deliver personalized care to parents. Researchers and health care providers could also strive to promote more peer-to-peer interactions among users. The provision of continuous, holistic, and family-centered care by health care professionals could also be emphasized. Moreover, policy changes regarding maternity and paternity leaves, availability of infant care centers, and flexible work arrangements could be further explored to promote healthy work-family balance for parents.

Proof-of-concept for an automatable mortality prediction scoring in hospitalised older adults.

Introduction: It is challenging to prognosticate hospitalised older adults. Delayed recognition of end-of-life leads to failure in delivering appropriate palliative care and increases healthcare utilisation. Most mortality prediction tools specific for older adults require additional manual input, resulting in poor uptake. By leveraging on electronic health records, we aim to create an automatable mortality prediction tool for hospitalised older adults. Methods: We retrospectively reviewed electronic records of general medicine patients ≥75 years at a tertiary hospital between April-September 2021. Demographics, comorbidities, ICD-codes, age-adjusted Charlson Comorbidity Index (CCI), Hospital Frailty Risk Score, mortality and resource utilization were collected. We defined early deaths, late deaths and survivors as patients who died within 30 days, 1 year, and lived beyond 1 year of admission, respectively. Multivariate logistic regression analyses were adjusted for age, gender, race, frailty, and CCI. The final prediction model was created using a stepwise logistic regression. Results: Of 1,224 patients, 168 (13.7%) died early and 370 (30.2%) died late. From adjusted multivariate regression, risk of early death was significantly associated with ≥85 years, intermediate or high frail risk, CCI > 6, cardiovascular risk factors, AMI and pneumonia. For late death, risk factors included ≥85 years, intermediate frail risk, CCI >6, delirium, diabetes, AMI and pneumonia. Our mortality prediction tool which scores 1 point each for age, pneumonia and AMI had an AUC of 0.752 for early death and 0.691 for late death. Conclusion: Our mortality prediction model is a proof-of-concept demonstrating the potential for automated medical alerts to guide physicians towards personalised care for hospitalised older adults.

Quality of Life and Its Associated Correlates of Parents of Children on the Autism Spectrum in Singapore.

This cross-sectional study aimed to assess Quality of life (QoL) of parents of children on the autism spectrum in Singapore and identify its associated factors. Parents of children (age ≥ 5 years) completed the Quality of Life in Autism scale which measures parental self-rated QoL (higher scores denote greater QoL), and the perceived impact of the child's autism-related behaviors on parents (higher scores denote lesser impact). Information on the child's degree of autism (measured by the Social Responsiveness Scale, second edition [SRS-2]), community and social participation and cognitive and adaptive functioning were also obtained. Participants were 86 parents with mean child age 6.3 years (SD 1.0). Univariate analysis results revealed greater participation in community and social events to be two modifiable factors associated with higher parental QoL. However, these factors were not found to be significant in the multivariate model. Higher autism features (represented by higher parent-rated SRS scores) was associated with a greater perceived impact of the child's behaviors by parents in both univariate and multivariate analyses. Of note, child's cognitive or adaptive skills were not significantly associated with either QoL measure. Equipping parents to handle autism-related behaviors can be useful to reduce their impact on parental QoL. Facilitating community participation for these children may positively influence caregiver QoL as well.

Clinical Service Incorporating Mobile Technology on Weight Loss in Patients With Metabolic Dysfunction-Associated Steatotic Liver Disease: A Translation From Research Trial.

BACKGROUND: The prevalence and healthcare cost of metabolic dysfunction-associated steatotic liver disease (MASLD) has increased alongside the epidemic surge in obesity and Type 2 diabetes. Weight loss through lifestyle modification remains the primary effective therapy for MASLD. Incorporation of mobile technology in lifestyle interventions has been previously found to be efficacious and cost-effective in facilitating weight loss. However, there is a paucity of studies that have successfully translated lifestyle research into clinical service for weight loss to alleviate disease burden. Our study aimed to describe the process of translating a mobile technology-enabled trial into a tertiary hospital outpatient dietetics service for patients with MASLD. METHODS: The Iowa Model of Evidence-Based Practice to Improve Quality Care was used as a framework for this paper to guide implementation at the organizational level. RESULTS: Regular engagement of key operational staff and the hospital management team facilitated open discussions of the challenges faced and enabled rapid implementation of strategies that contributed to the smooth piloting of the service. A service adoption rate of 81% was achieved. Preliminary outcome evaluation found that the percentage of patients achieving ≥ 5% weight loss from baseline at 6 months was comparable at 54% and 52% for the service and trial groups, respectively. CONCLUSIONS: Evaluation of the implementation process found that a hybrid model of care (in-person consultation supplemented with app coaching) preserved interpersonal connections while maximizing the convenience and scalability of mobile app-enabled service. Although high digital acceptance and adoption rates propelled by COVID-19-supported telehealth, it is prudent to assess patient's access to technology and digital literacy and offer resources to help them benefit from telehealth services.

Higher odds of periodontitis in systemic lupus erythematosus compared to controls and rheumatoid arthritis: a systematic review, meta-analysis and network meta-analysis.

Introduction: Periodontitis as a comorbidity in systemic lupus erythematosus (SLE) is still not well recognized in the dental and rheumatology communities. A meta-analysis and network meta-analysis were thus performed to compare the (i) prevalence of periodontitis in SLE patients compared to those with rheumatoid arthritis (RA) and (ii) odds of developing periodontitis in controls, RA, and SLE. Methods: Pooled prevalence of and odds ratio (OR) for periodontitis were compared using meta-analysis and network meta-analysis (NMA). Results: Forty-three observational studies involving 7,800 SLE patients, 49,388 RA patients, and 766,323 controls were included in this meta-analysis. The pooled prevalence of periodontitis in SLE patients (67.0%, 95% confidence interval [CI] 57.0-77.0%) was comparable to that of RA (65%, 95% CI 55.0-75.0%) (p>0.05). Compared to controls, patients with SLE (OR=2.64, 95% CI 1.24-5.62, p<0.01) and RA (OR=1.81, 95% CI 1.25-2.64, p<0.01) were more likely to have periodontitis. Indirect comparisons through the NMA demonstrated that the odds of having periodontitis in SLE was 1.49 times higher compared to RA (OR=1.49, 95% CI 1.09-2.05, p<0.05). Discussion: Given that RA is the autoimmune disease classically associated with periodontal disease, the higher odds of having periodontitis in SLE are striking. These results highlight the importance of addressing the dental health needs of patients with SLE. Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/ identifier CRD42021272876.
