RESUMEN
BACKGROUND: Understanding how SARS-CoV-2 breakthrough infections impacts the breadth of immune responses against existing and pre-emergent SARS-CoV-2 strains is needed to develop an evidence-based long-term immunisation strategy. METHODS: We performed a randomised, controlled trial to assess the immunogenicity of homologous (BNT162b2) versus heterologous (mRNA-1273) booster vaccination in 100 BNT162b2-vaccinated infection-naïve individuals enrolled from October 2021. Post hoc analysis was performed to assess the impact of SARS-CoV-2 infection on humoral and cellular immune responses against wild-type SARS-CoV-2 and/or Omicron subvariants. FINDINGS: 93 participants completed the study at day 360. 71% (66/93) of participants reported first SARS-CoV-2 Omicron infection by the end of the study with similar proportions of infections between homologous and heterologous booster groups (72.3% [34/47] vs 69.6% [32/46]; p = 0.82). Mean wildtype SARS-CoV-2 anti-S-RBD antibody level was significantly higher in heterologous booster group compared with homologous group at day 180 (14,588 IU/mL; 95% CI, 10,186-20,893 vs 7447 IU/mL; 4646-11,912; p = 0.025). Participants who experienced breakthrough infections during the Omicron BA.1/2 wave had significantly higher anti-S-RBD antibody levels against wildtype SARS-CoV-2 and antibody neutralisation against BA.1 and pre-emergent BA.5 compared with infection-naïve participants. Regardless of hybrid immunity status, wildtype SARS-CoV-2 anti-S-RBD antibody level declined significantly after six months post-booster or post-SARS-CoV-2 infection. INTERPRETATION: Booster vaccination with mRNA-1273 was associated with significantly higher antibody levels compared with BNT162b2. Antibody responses are narrower and decline faster among uninfected, vaccinated individuals. Boosters may be more effective if administered shortly before infection outbreaks and at least six months after last infection or booster. FUNDING: Singapore NMRC, USFDA, MRC.
RESUMEN
AIM: Existing studies on the cost of inflammatory arthritis (IA) and osteoarthritis (OA) are often cross-sectional and/or involve patients with various disease durations, thus not providing a comprehensive perspective on the cost of illness from the time of diagnosis. In this study, we therefore assessed the cost of lost productivity in an inception cohort of patients with IA and OA in the year before and after diagnosis. METHODS: Employment status, monthly income, days absent from work, and presenteeism were collected at diagnosis and 1 year later to estimate the annual costs of unemployment, absenteeism, and presenteeism using human capital approach. Non-parametric bootstrapping was performed to account for the uncertainty of the estimated costs. RESULTS: Compared to patients with OA (n = 64), patients with IA (n = 102, including 48 rheumatoid arthritis, 19 spondyloarthritis, 23 psoriatic arthritis, and 12 seronegative IA patients) were younger (mean age: 52.3 vs. 59.5 years) with a greater proportion receiving treatment (99.0% vs. 67.2%) and a greater decrease in presenteeism score (median: 15% vs 10%) 1 year after diagnosis. Annual costs of absenteeism and presenteeism were lower in patients with IA than those with OA both in the year before (USD566 vs. USD733 and USD8,472 vs. USD10,684, respectively) and after diagnosis (USD636 vs. USD1,035 and USD6,866 vs. USD9,362, respectively). CONCLUSION: Both IA and OA impose substantial cost of lost productivity in the year before and after diagnosis. The greater improvement in productivity seen in patients with IA suggests that treatment for IA improves work productivity.

Introduction: Hepatocellular carcinoma (HCC) is the sixth most commonly diagnosed cancer and the third leading cause of cancer death worldwide. While there has been rapid evolution in the treatment paradigm of HCC across the past decade, the extent to which these newly approved therapies are utilized in clinical practice in the real world is, however, unknown. The INSIGHT study was an investigator-initiated, multi-site longitudinal cohort study conducted to reflect real-world epidemiology and clinical practice in Asia-Pacific in the immediate 7-year period after the conclusion of the BRIDGE study. Methods: Data were collected both retrospectively (planned 30% of the total cohort size) and prospectively (planned 70%) from January 2013 to December 2019 from eligible patients newly diagnosed with HCC from 33 participating sites across 9 Asia-Pacific countries. Results: A total of 2,533 newly diagnosed HCC patients (1,052 in retrospective cohort and 1,481 in prospective cohort) were enrolled. The most common risk factor was hepatitis B in all countries except Japan, Australia, and New Zealand, where the prevalence of hepatitis C and diabetes were more common. The top three comorbidities reported in the INSIGHT study include cirrhosis, hypertension, and diabetes. We observe high heterogeneity in the first-line treatment recorded across countries and across disease stages, which significantly affects survival outcomes. Stratification by factors such as etiologies, tumor characteristics, the presence of extrahepatic metastases or macrovascular invasion, and the use of subsequent lines of treatment were performed. Conclusion: The INSIGHT study describes a wide spectrum of clinical management practices in HCC, where patient demographics, differential costs, and patient access to therapies may lead to wide geographical variations through the patient's treatment cycle, from diagnosis to clinical outcome. The high heterogeneity in patient outcomes demonstrates the need for more robust and clinical management strategies to be designed and adopted to bring about better patient outcomes.
RESUMEN
Introduction: Physical inactivity is a risk factor for obesity and non-communicable diseases. Despite myriad health and non-health benefits resulting from physical activity (PA), most individuals do not meet PA recommendations. Providing an incentive for meeting activity goals may increase activity levels. Classical economists argue that cash is the best incentive. Behavioral economists have posited that hedonic (pleasurable) incentives (e.g., massages, restaurant meals) may be superior to cash when incentives are offered over multiple time periods. To date, no studies have directly compared the effectiveness of cash versus hedonic incentives in promoting PA across multiple time periods. Methods: We conducted a two-arm, parallel, 4-month randomized controlled trial with healthy adults in Singapore where participants were randomized to either cash or hedonic incentives. Participants could earn up to SGD50 (≈USD37) in cash or hedonic incentives each month they met the study's step target of 10,000 steps daily on at least 20/25 days out of the first 28 days of a month. The primary objective was to compare the mean proportion of months that participants met the step target between the two arms. Results: By month 4, participants in the cash (N = 154) and hedonic incentive (N = 156) arms increased their mean daily steps by 870 (p < 0.001) and 1,000 steps (p < 0.001), respectively. The mean proportion of months the step target was achieved was 90.53 and 88.34 for participants in the cash and hedonic incentive arms respectively, but differences across arms were small and not statistically significant for this or any outcome assessed. Conclusion: Our findings suggest that both cash and hedonic incentives are effective at promoting physical activity but that neither strategy is clearly superior.Clinical trial registration: ClinicalTrials.gov, NCT04618757 registered on November 6, 2020.

OBJECTIVE: We evaluated the impact of intermittently scanned continuous glucose monitoring(is-CGM)over self-monitoring of blood glucose(SMBG) in the context of diabetes self-management education (DSME) in sub-optimally controlled type 2 diabetes(T2D) in a multi-ethnicsetting. RESEARCH DESIGN AND METHOD: Randomized-controlled, open-label trial (NCT04564911), of T2D with HbA1c ≥ 7.5-≤10 %, on oral agents with/without basal insulin was carried out. Intervention arm received 6 weeks(w) continuous is-CGM, followed by one is-CGM/month till 24w. Control arm was advised to perform 4 SMBG/day. Educationwas delivered at weeks 0, 2, 8, 16. PRIMARY OUTCOME: Change in HbA1c from baseline at 24w. Modified intention-to-treat (mITT) analysis with linear mixed-effect model for repeated measurementswas performed. RESULTS: 176 subjects, age 55 ± 10.7 years(y), DM duration 11 ± 7.3y, BMI 27.8 ± 5.9 kg/m2, 58 % Male, 29.5 % basal insulin users were analysed. Within each arm,from baseline to 24w, mean HbA1c decreasedby -0.6 % (-6.6.mmol/mol, p-value < 0.01)and weight decreased(isCGM: -1.44 kg; SMBG: -1.25 kg, both p < 0.01). These changes were sustained to one year. However, there wasno significant difference in these parameters between arms (p-value > 0.05). CONCLUSION: In the context of DSME, use of either SMBG or is-CGM led to improved glycaemia and reduced weight over a period of 24 weeks, sustained to one year.

Hypertension is a leading risk factor for cardiovascular disease in South Asia. The authors aimed to assess the cross-country differences in 24-h ambulatory, daytime, and nighttime systolic blood pressure (SBP) among rural population with uncontrolled clinic hypertension in Bangladesh, Pakistan, and Sri Lanka. The authors studied patients with uncontrolled clinic hypertension (clinic BP ≥ 140/90 mmHg) who underwent ambulatory blood pressure monitoring (ABPM) during the baseline assessment as part of a community-based trial. The authors compared the distribution of ABPM profiles of patients across the three countries, specifically evaluating ambulatory SBP levels with multivariable models that adjusted for patient characteristics. Among the 382 patients (mean age, 58.3 years; 64.7% women), 56.5% exhibited ambulatory hypertension (24-h ambulatory BP ≥ 130/80 mmHg), with wide variation across countries: 72.6% (Bangladesh), 50.0% (Pakistan), and 51.0% (Sri Lanka; P < .05). Compared to Sri Lanka, adjusted mean 24-h ambulatory, daytime, and nighttime SBP were higher by 12.24 mmHg (95% CI 4.28-20.20), 11.96 mmHg (3.87-20.06), and 12.76 mmHg (4.51-21.01) in Bangladesh, separately. However, no significant differences were observed between Pakistan and Sri Lanka (P > .05). Additionally, clinic SBP was significantly associated with 24-h ambulatory (mean 0.38, 95% CI 0.28-0.47), daytime (0.37, 0.27-0.47), and nighttime SBP (0.40, 0.29-0.50) per 1 mmHg increase. The authors observed substantial cross-country differences in the distribution of ABPM profiles among patients with uncontrolled clinic hypertension in rural South Asia. The authors findings indicated the need to incorporate 24-h BP monitoring to mitigate cardiovascular risk, particularly in Bangladesh.

BACKGROUND: Parent-reported experience measures are part of pediatric Quality of Care (QoC) assessments. However, existing measures were not developed for use across multiple healthcare settings or throughout the illness trajectory of seriously ill children. Formative work involving in-depth interviews with parents of children with serious illnesses generated 66 draft items describing key QoC processes. Our present aim is to develop a comprehensive parent-reported experience measure of QoC for children with serious illnesses and evaluate its content validity and feasibility. METHODS: For evaluating content validity, we conducted a three-round Delphi expert panel review with 24 multi-disciplinary experts. Next, we pre-tested the items and instructions with 12 parents via cognitive interviews to refine clarity and understandability. Finally, we pilot-tested the full measure with 30 parents using self-administered online surveys to finalize the structure and content. RESULTS: The Delphi expert panel review reached consensus on 68 items. Pre-testing with parents of seriously ill children led to consolidation of some items. Pilot-testing supported feasibility of the measure, resulting in a comprehensive measure comprising 56 process assessment items, categorized under ten subthemes and four themes: (1) Professional qualities of healthcare workers, (2) Supporting parent-caregivers, (3) Collaborative and holistic care, and (4) Efficient healthcare structures and standards. We named this measure the PaRental Experience with care for Children with serIOUS illnesses (PRECIOUS). CONCLUSIONS: PRECIOUS is the first comprehensive measure and has the potential to standardize assessment of QoC for seriously ill children from parental perspectives. PRECIOUS allows for QoC process evaluation across contexts (such as geographic location or care setting), different healthcare workers, and over the illness trajectory for children suffering from a range of serious illnesses.

OBJECTIVES: To determine the measurement properties of PaRental Experience with care for Children with serIOUS illnesses (PRECIOUS), a parent-reported measure of Quality of Care for seriously ill children across care settings and illness trajectories. STUDY DESIGN AND SETTING: Parents self-administered baseline and 2-week follow-up surveys online. Exploratory Factor Analysis was used to determine PRECIOUS's factor structure and select items. Internal consistency was evaluated with Cronbach's α, test-retest reliability with intraclass correlation coefficients, and convergent validity with Spearman's correlations between PRECIOUS scales and subscales of Measure of Processes of Care and Quality of Children's Palliative Care Instrument. RESULTS: Of 152 parents [108 (71%) mothers, 44 (29%) fathers] who completed the baseline survey, 123 (81%) completed follow-up. Exploratory Factor Analysis grouped PRECIOUS into five scales: collaborative and goal-concordant care (12 items), caregiver support and respectful care (15 items), access to financial and medical resources (five items), reducing caregiving stressors (nine items), and hospitalization-specific processes (four items). Root Mean Square Error of Approximation was 0.040 and Comparative Fit Index was 0.980. Cronbach's α ranged from 0.85 to 0.96. Intraclass correlation coefficients ranged from 0.72 to 0.86. Significant correlations with Measure of Processes of Care and Quality of Children's Palliative Care Instrument confirmed convergent validity. The original 56-item tool was reduced to 45 items. CONCLUSION: PRECIOUS demonstrates satisfactory measurement properties for assessing Quality of Care for seriously ill children.

BACKGROUND: Type 2 diabetes (T2D), a major risk factor for cardiovascular disease and other adverse health conditions, is on the rise in Singapore. TRIPOD is a randomized controlled trial aimed to determine whether complementing usual care with an evidence-based diabetes management package (DMP) -comprising access to an evidence-based app, health coaching, pedometer, glucometer and weighing scale, with or without a financial rewards scheme (M-POWER rewards), can improve mean HbA1c levels at months 6 and 12. METHODS: The protocol was published in Trials, accessible via https://trialsjournal.biomedcentral.com/articles/10.1186/s13063-019-3749-x 1. This manuscript updates the protocol with changes to the study design due to challenges with recruitment and presents baseline characteristics. Key updates include changing the arm allocation ratio from 1:1:1 (Arm 1-Usual Care: Arm 2-DMP: Arm 3-DMP+M-POWER rewards) to 10:1:10, the sample size from 339 to 269, the intervention period from two to one year, and the primary hypothesis to focus solely on differences between Usual Care and DMP+M-POWER rewards. Recruitment for the study began on 19 October 2019 and ended on 4 June 2022. RESULTS: The average age of participants was 55.0 (SD9.7) years old and 64.2% were male. The majority of participants (76.8%) were Chinese, 4.9% Malay and 18.3% Indian and of other ethnicities. 67.0% had a monthly household income of SGD$4000 or more. The mean baseline HbA1c was 8.10% (SD 0.95) and the mean body mass index was 26.8 kg/m2 (SD 5.3). DISCUSSION: The final participant completed month 12 follow-up data collection on 8 June 2023. All pre-planned analyses will be conducted and final results reported. TRIAL REGISTRATION: ClinicalTrials.gov NCT03800680 . Registered on 11 January 2019.

To compare functional health status and Health Related Quality of Life (HRQoL) between Fontan and non-congenital heart disease (CHD) patients in an Asian population. Functional health status and HRQoL (New York Heart Association (NYHA) functional class, Duke Activity Status Index (DASI), HeartQol and EQ-5D-5L) were measured. A total of 65 patients (twenty Fontan patients, mean age 28 ± 5; and 45 age-matched non-CHD patients, mean age 33 ± 5) were recruited. After adjustment for age, gender and ethnicity, there were no significant differences in functional health status and HRQoL between groups. In an Asian population, Fontan patients have similar functional health status and Health Related Quality of Life compared to non-CHD patients.

PURPOSE: To evaluate the measurement properties of the 15-item Singapore Caregiver Quality of Life Scale (SCQOLS-15) in family caregivers of patients with heart diseases. METHODS: The SCQOLS-15 survey was self-administered by family caregivers of patients with chronic heart diseases, at baseline and 1 week later. The criterion validity of SCQOLS-15 and its domain scores was assessed by calculating the Spearman correlation coefficient (ρ) with the Brief Assessment Scale for Caregivers (BASC), Caregiver Reaction Assessment (CRA), and their sub-scores. Known-group validity was assessed using the New York Heart Association (NYHA) functional class. Test-retest reliability was evaluated using the intraclass correlation coefficient (ICC). RESULTS: Of the 327 caregivers included, 65% were adult children and 28% were spouses. The distribution of NYHA classes of the patients was I: 27%, II: 40%, III: 24%, and IV: 9%. There was a positive correlation between the SCQOLS-15 and BASC total scores (ρ = 0.7). SCQOLS-15 domain scores were also correlated with BASC and CRA sub-scores as per a priori hypotheses, with absolute values of ρ ranging from 0.4 to 0.6. The mean values of SCQOLS-15 total and all domain scores were lower among caregivers of patients with NYHA class III/IV compared to those of class I/II patients (each P < 0.05). Among 146 caregivers who completed the follow-up and self-rated a stable quality-of-life, ICCs for test-retest reliability of SCQOLS-15 total and all domain scores were ≥ 0.8. CONCLUSION: The SCQOLS-15 is a valid and reliable instrument for measuring the quality of life in caregivers of heart disease patients.

OBJECTIVES: Reduced work productivity (WP), measured by work productivity loss (WPL) and work disability (WD), is common in patients with inflammatory arthritis (IA) and osteoarthritis (OA) but is not well characterised. We aimed to assess if there were any improvements in WP (WPL and WD) from diagnosis (T1) to six months later (T2) and to explore associations between WP at T2 and health status at T1 among these patients. METHODS: Patients were surveyed for work characteristics, work ability, WP and health status including physical functioning and vitality at T1 and T2. Associations between WP at T2 and health status at T1 were explored using regression models. RESULTS: Patients with IA (n=109) were younger than those with OA (n=70) (mean age: 50.5 vs. 57.7 years). The median WPL score decreased from 30.0 to 10.0 in patients with IA and from 20.0 to 0.0 in patients with OA, while the proportion reporting WD decreased from 52.3% to 45.3% in patients with IA and increased from 52.2% to 56.5% in patients with OA from T1 to T2. Physical functioning at T1 (coefficient = -0.35) was significantly associated with WPL at T2. Vitality at T1 (coefficient = 0.03) was associated with WD at T2. CONCLUSIONS: Greater improvements in WP were observed among patients with IA than those with OA in the first six months after diagnosis. This provides a basis for healthcare professionals to aim for greater improvements in work and health status for patients with IA.

OBJECTIVE: The Pre-Diabetes Interventions and Continued Tracking to Ease-out Diabetes (Pre-DICTED) Program is a diabetes prevention trial comparing the diabetes conversion rate at 3 years between the intervention group, which receives the incentivized lifestyle intervention program with stepwise addition of metformin, and the control group, which receives the standard of care. We describe the baseline characteristics and compare Pre-DICTED participants with other diabetes prevention trials cohort. RESEARCH DESIGN AND METHODS: Participants were aged between 21 and 64 years, overweight (body mass index (BMI) ≥23.0 kg/m2), and had pre-diabetes (impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT)). RESULTS: A total of 751 participants (53.1% women) were randomized. At baseline, mean (SD) age was 52.5 (8.5) years and mean BMI (SD) was 29.0 (4.6) kg/m2. Twenty-three per cent had both IFG and IGT, 63.9% had isolated IGT, and 13.3% had isolated IFG. Ethnic Asian Indian participants were more likely to report a family history of diabetes and had a higher waist circumference, compared with Chinese and Malay participants. Women were less likely than men to meet the physical activity recommendations (≥150 min of moderate-intensity physical activity per week), and dietary intake varied with both sex and ethnicity. Compared with other Asian diabetes prevention studies, the Pre-DICTED cohort had a higher mean age and BMI. CONCLUSION: The Pre-DICTED cohort represents subjects at high risk of diabetes conversion. The study will evaluate the effectiveness of a community-based incentivized lifestyle intervention program in an urban Asian context.

BACKGROUND: The incidence of Gram-negative bacteraemia is rising globally and remains a major cause of morbidity and mortality. The majority of patients with Gram-negative bacteraemia initially receive intravenous (IV) antibiotic therapy. However, it remains unclear whether patients can step down to oral antibiotics after appropriate clinical response has been observed without compromising outcomes. Compared with IV therapy, oral therapy eliminates the risk of catheter-associated adverse events, enhances patient quality of life and reduces healthcare costs. As current management of Gram-negative bacteraemia entails a duration of IV therapy with limited evidence to guide oral conversion, we aim to evaluate the clinical efficacy and economic impact of early stepdown to oral antibiotics. METHODS: This is an international, multicentre, randomised controlled, open-label, phase III, non-inferiority trial. To be eligible, adult participants must be clinically stable / non-critically ill inpatients with uncomplicated Gram-negative bacteraemia. Randomisation to the intervention or standard arms will be performed with 1:1 allocation ratio. Participants randomised to the intervention arm (within 72 h from index blood culture collection) will be immediately switched to an oral fluoroquinolone or trimethoprim-sulfamethoxazole. Participants randomised to the standard arm will continue to receive IV therapy for at least 24 h post-randomisation before clinical re-assessment and decision-making by the treating doctor. The recommended treatment duration is 7 days of active antibiotics (including empiric therapy), although treatment regimen may be longer than 7 days if clinically indicated. Primary outcome is 30-day all-cause mortality, and the key secondary outcome is health economic evaluation, including estimation of total healthcare cost as well as assessment of patient quality of life and number of quality-adjusted life years saved. Assuming a 30-day mortality of 8% in the standard and intervention arms, with 6% non-inferiority margin, the target sample size is 720 participants which provides 80% power with a one-sided 0.025 α-level after adjustment for 5% drop-out. DISCUSSION: A finding of non-inferiority in efficacy of oral fluoroquinolones or trimethoprim-sulfamethoxazole versus IV standard of care antibiotics may hypothetically translate to wider adoption of a more cost-effective treatment strategy with better quality of life outcomes.

OBJECTIVE: This scoping review aimed to: 1) identify parent-reported experience measures (PaREMs) for parents of children with serious illnesses from peer-reviewed literature, 2) map the types of care experience being evaluated in PaREMs, 3) identify and describe steps followed in the measure development process, including where gaps lie and how PaREMs may be improved in future efforts, and 4) help service providers choose a PaREM suitable for their service delivery setting and strategy. DATA SOURCES: Relevant articles were systematically searched from PubMed, CINAHL, and Scopus EBSCOhost databases until June 10, 2021, followed by a manual reference list search of highly relevant articles. STUDY SELECTION: Abstracts were screened, followed by a full-text review using predetermined inclusion and exclusion criteria. DATA EXTRACTION: A standardized data extraction tool was used. DATA SYNTHESIS: Sixteen PaREMs were identified. There were large variances in the development processes across measures, and most have been developed in high-income, English-speaking Western countries. Most only assess the quality of acute inpatient care. Few measures can be used by multiple service providers or chronic care, and many do not capture all relevant domains of the parent experience. CONCLUSIONS: Service providers should integrate PaREMs into their settings to track and improve the quality of care. Given the multidisciplinary nature of pediatric care and the often-unpredictable disease trajectories of seriously ill children, measures that are applicable to multiple providers and varying lengths of care are essential for standardized assessment of quality of care and coordination among providers. To improve future PaREM development, researchers should follow consistent and methodologically robust steps, ideally in more diverse sociocultural and health systems contexts. Future measures should widen their scope to be applicable over the disease trajectory and to multiple service providers in a child's network of care for a comprehensive evaluation of experience.

Aim: We explored the association between preoperative anthropometry and biochemistry, and postoperative outcomes in infants with CHD after cardiac surgery, as infants with congenital heart disease (CHD) often have feeding difficulties and malnutrition. Methodology: This was a retrospective review of infants (≤ 1-year-old) who underwent congenital heart surgery. Preoperative anthropometryin terms of preoperative weight-for-age z-score (WAZ), length-for-age z-score (LAZ), as well as preoperative serum albumin and hemoglobin concentrations, were evaluated against 6-month mortality, and morbidity outcomes including postoperative complications, vasoactive inotrope score, duration of mechanical ventilation, length of stay in the pediatric intensive care unit and in hospital, using the logistic regression or median regression models accounting for infant-level clustering. Results: One hundred and ninety-nine operations were performed in 167 infants. Mean gestational age at birth was 38.0 (SD 2.2) weeks (range 26 to 41 weeks). Thirty (18.0%) infants were born preterm (<37 weeks). The commonest acyanotic and cyanotic lesions were ventricular septal defect (26.3%, 44/167), and tetralogy of Fallot (13.8%, 23/167), respectively. Mean age at cardiac surgery was 94 (SD 95) days. Feeding difficulties, including increased work of breathing during feeding, diaphoresis, choking or coughing during feeding, and inability to complete feeds, was present in 54.3% (108/199) of infants prior to surgery, of which 21.6% (43/199) required tube feeding. The mean preoperative WAZ was-1.31 (SD 1.79). Logistic regression models showed that low preoperative WAZ was associated with increased risk of postoperative complications (odds ratio 1.82; p = 0.02), and 6-month mortality (odds ratio 2.38; p = 0.008) following CHD surgery. There was no meaningful association between the other preoperative variables and other outcomes. Conclusion: More than 50% of infants with CHD undergoing cardiac surgery within the first year of life have feeding difficulties, of which 22% require to be tube-fed. Low preoperative WAZ is associated with increased postoperative complications and 6-month mortality.
RESUMEN
OBJECTIVES: Several studies have shown that patients with heart disease value hypothetical health states differently from the general population. We aimed to investigate the health preferences of patients with heart disease and develop a value set for the 5-level EQ-5D (EQ-5D-5L) based on these patient preferences. METHODS: Patients with confirmed heart disease were recruited from 2 hospitals in Singapore. A total of 86 EQ-5D-5L health states (10 per patient) were valued using a composite time trade-off method according to the international valuation protocol for EQ-5D-5L; 20-parameter linear models and 8-parameter cross-attribute level effects models with and without an N45 term (indicating whether any health state dimension at level 4 or 5 existed) were estimated. Each model included patient-specific random intercepts. Model performance was evaluated for out-of-sample and in-sample predictive accuracy in terms of root mean square error. The discriminative ability of the utility values was assessed using heart disease-related functional classes. RESULTS: A total of 576 patients were included in the analysis. The preferred model, with the lowest out-of-sample root mean square error, was a 20-parameter linear model including N45. Predicted utility values ranged from -0.727 for the worst state to 1 for full health; the value for the second-best state was 0.981. Utility values demonstrated good discriminative ability in differentiating among patients of varied functional classes. CONCLUSIONS: An EQ-5D-5L value set representing the preferences of patients with heart disease was developed. The value set could be used for patient-centric economic evaluation and health-related quality of life assessment for patients with heart disease.

INTRODUCTION: Protein-energy malnutrition, increased catabolism and inadequate nutritional support leads to loss of lean body mass with muscle wasting and delayed recovery in critical illness. However, there remains clinical equipoise regarding the risks and benefits of protein supplementation. This pilot trial will determine the feasibility of performing a larger multicentre trial to determine if a strategy of protein supplementation in critically ill children with body mass index (BMI) z-score ≤-2 is superior to standard enteral nutrition in reducing the length of stay in the paediatric intensive care unit (PICU). METHODS AND ANALYSIS: This is a randomised controlled trial of 70 children in two PICUs in Singapore. Children with BMI z-score ≤-2 on PICU admission, who are expected to require invasive mechanical ventilation for more than 48 hours, will be randomised (1:1 allocation) to protein supplementation of ≥1.5 g/kg/day in addition to standard nutrition, or standard nutrition alone for 7 days after enrolment or until PICU discharge, whichever is earlier. Feasibility outcomes for the trial include effective screening, satisfactory enrolment rate, timely protocol implementation (within first 72 hours) and protocol adherence. Secondary outcomes include mortality, PICU length of stay, muscle mass, anthropometric measurements and functional outcomes. ETHICS AND DISSEMINATION: The trial protocol was approved by the institutional review board of both participating centres (Singhealth Centralised Institutional Review Board and National Healthcare Group Domain Specific Review Board) under the reference number 2020/2742. Findings of the trial will be disseminated through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER: NCT04565613.

To evaluate the trajectories and sustainability of health-related quality of life (HRQoL) outcomes after palliative gastrointestinal (GI) surgery and perioperative factors associated with HRQoL improvement postsurgery. Background: Palliative patients face a wide range of physical, emotional, social, and functional challenges. In evaluating the efficacy of palliative surgical interventions, a major pitfall of traditional surgical outcome measures is that they fall short of measuring outcomes that are meaningful to patients during end-of-life. HRQoL tools may provide a more comprehensive assessment of the true value and impact of palliative surgery. Methods: We prospectively recruit advanced cancer patients undergoing palliative GI surgery. The Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire was administered before and at regular intervals after surgery. HRQoL improvement was defined as ≥4-points increment in FACT-G total score over baseline. Duration of sustained HRQoL improvement above this threshold and factors associated with varying extents of HRQoL change were evaluated. Results: Of the 65 patients, intestinal obstruction was the most common indication for surgery (70.8%). The mean baseline FACT-G total score was 70.7 (95% CI: 66.3-75.1). Forty-six (70.8%) patients experienced HRQoL improvement after surgery. This HRQoL improvement was sustained over a median duration of 3.5 months and was driven mainly by improvements in patients' physical and emotional well-being. Albumin was significantly associated with the extent of HRQoL improvements (P = 0.043). Conclusion: A clinically significant and sustained improvement in HRQoL was observed after palliative GI surgery. Patients with higher preoperative albumin levels were more likely to experience HRQoL improvements.
RESUMEN
INTRODUCTION/OBJECTIVES: To address the diagnostic delay in axial spondyloarthritis (axSpA), we have cross-culturally adapted the Hamilton axSpA questionnaire, a self-administered screening questionnaire, in the Singapore population. In this study, we compared the performance of various scoring methods for this questionnaire in detecting axSpA. METHOD: The questionnaire was self-administered by eligible subjects. Scoring methods included method A, the original questionnaire scoring, and methods B-E, scoring developed based on the Assessment of SpondyloArthritis International Society (ASAS) criteria for inflammatory back pain (IBP) and the referral, classification and both referral and classification of axSpA, respectively. The reference standard was diagnosis by a rheumatologist. Since the ASAS criteria-based scoring methods were mainly based on clinical axSpA features, self-report and rheumatologist-assessment of clinical axSpA features were also compared in subjects with axSpA. RESULTS: Of 1418 subjects (age: 54 ± 14 years, female: 73%) recruited, 46 were diagnosed with axSpA by a rheumatologist. Sensitivities of methods A-E were 35%, 61%, 63%, 48% and 83%, respectively. Self-report of clinical axSpA features exceeded rheumatologist-assessment for arthritis (83 vs 26%), good response to NSAIDs (37 vs 30%), enthesitis (35 vs 30%), dactylitis (20 vs 2%) and family history for axSpA (13 vs 4%). The reverse was true for IBP (41 vs 63%) and uveitis (4 vs 15%). CONCLUSIONS: A self-administered questionnaire using the ASAS referral and classification criteria-based scoring yielded relatively high sensitivity in detecting axSpA in subjects newly referred to rheumatology clinics. This supports its evaluation as a screening and referral tool in the general population in future studies. Key Points ⢠A self-administered questionnaire could be used as a screening and referral tool. ⢠ASAS referral and classification criteria-based scoring yielded relatively high sensitivity. ⢠Inaccurate perception of clinical axSpA features was observed in axSpA patients.
