'Been there, experienced that': A qualitative study on the experiences and perceptions of online peer volunteers in supporting Singaporean mothers at risk of depression.

BACKGROUND: Online peer support is a useful source of support for parents during the perinatal period, associated with improved psychological outcomes. Past research has found that peer support providers themselves gain from providing peer support as well, making it mutually beneficial. As current maternity care services are insufficient to meet the support needs of parents, the Supportive Parenting App (SPA) intervention was developed to offer them informational, appraisal and emotional support during the perinatal period. It consists of mobile health application-based educational support and online peer support provided by trained peer volunteers, to prevent the development of postnatal depression. OBJECTIVE: To explore the experiences of peer volunteers with providing online peer support to parents during the perinatal period, as well as to identify areas of improvement for the SPA intervention. METHODS: A qualitative descriptive design was adopted. This study took place from October 2020 to August 2021 in two tertiary public healthcare institutions in Singapore. A total of 18 peer volunteers were invited for individual semi-structured interviews. The interviews were audio recorded and transcribed verbatim, and thematic analysis was used to analyse the data. RESULTS: Four themes were emerged as follows: (1) 'Being there': Reminiscing about and healing of own postnatal depression experience; (2) Building rapport with parents; (3) Parents in mind: Mutual sharing of knowledge and how to support new parents better; (4) Ensuring good quality peer support. CONCLUSIONS: The peer volunteers felt that their experience was fulfilling and healing. Frequent contact, sharing of SPA resources and self-disclosure were found to help engage the new parents and build rapport between peer volunteers and parents. Challenges described by the peer volunteers have identified possible areas in which the SPA intervention can be improved. IMPLICATIONS FOR CARE: Communication between peer program facilitators, managers and peer volunteers can be enhanced to ensure that peer volunteers are more sensitive and precise when providing support or information. This can improve rapport building between parents and peer volunteers, which will in turn maximize the benefits that parents can reap through online peer-to-peer support. IMPACT: This study explored the perceptions of peer volunteers who provided online peer support to parents across the perinatal period. Peer volunteers felt that the SPA intervention was meaningful and that providing peer support was a healing experience. They were able to learn about the experiences of other mothers with postpartum depression while sharing their own past experiences. Thus, both parents and peer volunteers can benefit from engaging in online peer support programs. Technology-based interventions like the Supportive Parenting App (SPA) can be a suitable complement to maternity care services by providing parents access to medically accurate information and social support. Additionally, more experienced mothers can engage in fulfilling experiences through volunteering for new mothers who may benefit from informational, appraisal and emotional support. REPORTING METHOD: This study follows the reporting guidelines as stated by the Consolidated criteria for reporting qualitative research (COREQ) checklist. PATIENT OR PUBLIC CONTRIBUTION: Parents and peer volunteers contributed ideas that aided with the design of the mobile app. Many topics added to the educational materials were suggested by these parents as well. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: This study showed that sufficient training can be provided to lay peer volunteers to help them support other parents, buffering the pressure exerted on the healthcare industry due to the rising demand for healthcare services. The provision of such support is also beneficial for the peer volunteers themselves, as they find it meaningful and educational. Program developers of parenting and peer volunteering interventions can draw on the findings of this study to improve the effectiveness of these programs.

Sea-level rise and the emergence of a keystone grazer alter the geomorphic evolution and ecology of southeast US salt marshes.

Keystone species have large ecological effects relative to their abundance and have been identified in many ecosystems. However, global change is pervasively altering environmental conditions, potentially elevating new species to keystone roles. Here, we reveal that a historically innocuous grazer-the marsh crab Sesarma reticulatum-is rapidly reshaping the geomorphic evolution and ecological organization of southeastern US salt marshes now burdened by rising sea levels. Our analyses indicate that sea-level rise in recent decades has widely outpaced marsh vertical accretion, increasing tidal submergence of marsh surfaces, particularly where creeks exhibit morphologies that are unable to efficiently drain adjacent marsh platforms. In these increasingly submerged areas, cordgrass decreases belowground root:rhizome ratios, causing substrate hardness to decrease to within the optimal range for Sesarma burrowing. Together, these bio-physical changes provoke Sesarma to aggregate in high-density grazing and burrowing fronts at the heads of tidal creeks (hereafter, creekheads). Aerial-image analyses reveal that resulting "Sesarma-grazed" creekheads increased in prevalence from 10 ± 2% to 29 ± 5% over the past <25 y and, by tripling creek-incision rates relative to nongrazed creekheads, have increased marsh-landscape drainage density by 8 to 35% across the region. Field experiments further demonstrate that Sesarma-grazed creekheads, through their removal of vegetation that otherwise obstructs predator access, enhance the vulnerability of macrobenthic invertebrates to predation and strongly reduce secondary production across adjacent marsh platforms. Thus, sea-level rise is creating conditions within which Sesarma functions as a keystone species that is driving dynamic, landscape-scale changes in salt-marsh geomorphic evolution, spatial organization, and species interactions.

A multicenter observational study on outcomes of moderate and severe pediatric traumatic brain injuries-time to reappraise thresholds for treatment.

PURPOSE: Children with moderate traumatic brain injury (modTBI) (Glasgow Coma Scale (GCS) 9-13) may benefit from better stratification. We aimed to compare neurocritical care utilization and functional outcomes between children with high GCS modTBI (hmodTBI, GCS 11-13), low GCS modTBI (lmodTBI, GCS 9-10), and severe TBI (sTBI, GCS ≤ 8). We hypothesized that patients with lmodTBI have higher neurocritical care needs and worse outcomes than patients with hmodTBI and are similar to patients with sTBI. METHODS: Prospective observational study from June 2018 to October 2022 in 28 pediatric intensive care units (PICU) in Asia, South America, and Europe. We included children (age < 18 years) with modTBI and sTBI admitted to PICU and measured functional outcomes at 3 months using the Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds, scale 1-8, 1 = upper good recovery, 8 = death). RESULTS: We analyzed 409 patients: 98 (24%) and 311 (76%) with modTBI and sTBI, respectively. Patients with lmodTBI (vs. hmodTBI) were more likely to have invasive ICP monitoring (32.3% vs. 4.5%, p < 0.001), longer PICU stay (days, median [IQR]; 5.00 [4.00, 9.75] vs 4.00 [2.00, 5.00], p = 0.007), and longer hospital stay (days, median [IQR]: 13.00 [8.00, 17.00] vs. 8.00 [5.00, 12, 25], p = 0.015). Median GOS-E Peds scores were significantly different (hmodTBI (1.00 [1.00, 3.00]), lmodTBI (3.00 [IQR 2.00, 5.75]), and sTBI (5.00 [IQR 1.00, 6.00]) (p < 0.001)). After adjusting for age, sex, presence of polytrauma and cerebral edema, lmodTBI, and sTBI remained significantly associated with higher GOS-E scores (adjusted coefficient (standard error): 1.24 (0.52), p = 0.018, and 1.27 (0.33), p < 0.001, respectively) compared with hmodTBI. CONCLUSIONS: Children with lmodTBI have higher rates of neurocritical care utilization and worse functional outcomes than those with hmodTBI but better than those with sTBI. Children with lmodTBI may benefit from guideline-based management similar to what is implemented in children with sTBI. This work was performed in hospitals within the PACCMAN and LARed networks.

Evaluating the Effectiveness of the Supportive Parenting App on Parental Outcomes: Randomized Controlled Trial.

BACKGROUND: Adjusting to new or additional parenting responsibilities increases stress and affects parental well-being. Existing research has highlighted both parents' desire to receive more support. It has also been found that receiving sufficient social support enhances parenting outcomes. With the increasing popularity of mobile health apps, a Supportive Parenting App (SPA) intervention was developed to fulfill the support needs of parents during the perinatal period. OBJECTIVE: This study aimed to examine the effectiveness of the SPA on parental outcomes during the perinatal period. METHODS: A 2-group pretest and repeated posttest randomized controlled trial was conducted wherein 200 couples (N=400 mothers and fathers) were recruited from 2 public health care institutions in Singapore. Parents were randomly assigned to intervention (100/200, 50%) or control (100/200, 50%) groups. The SPA intervention consisted of a mobile app-based psychoeducation and peer support program to support parents from pregnancy to 6 months post partum. The outcome measures included postnatal depression, anxiety, parental bonding, parental self-efficacy, perceived social support, and parenting satisfaction. Data were collected at baseline (at >24 weeks of gestation-age of viability in Singapore) and at the first, second, fourth, sixth, ninth, and 12th month post partum. Linear mixed models were used to compare parental outcomes between the groups, and a linear mixed model for repeated measures was used to examine within-group changes. RESULTS: Parents in the intervention group mostly showed better outcomes compared with those in the control group. Parents in the intervention group had higher perceived social support than those in the control group at the first (effect size=1.59, 95% CI 0.38-2.80; Cohen standardized effect size=1.31; P=.01), second (effect size=1.98, 95% CI 1.09-2.88; Cohen standardized effect size=2.21; P=.003), and fourth (effect size=2.57, 95% CI 1.62-3.51; Cohen standardized effect size=2.72; P=.048) months post partum. However, parents in the intervention group showed significantly poorer parental bonding (effect size=1.67, 95% CI 0.24-3.11; Cohen standardized effect size=1.16; P=.02). The other parental outcomes did not differ significantly between groups. The scores of mothers and fathers also differed significantly for all outcomes except parental self-efficacy. CONCLUSIONS: Parents in the intervention group generally fared better, especially regarding perceived social support. However, the lack of statistical significance in most outcomes showed the limited effectiveness of the SPA intervention, which may be because of the COVID-19 pandemic. Parental differences in outcome scores suggest that mothers and fathers have different support needs; therefore, interventions should be tailored accordingly. Further improvements and evaluations are needed to examine the effectiveness of the SPA intervention in enhancing parental outcomes. Despite statistically insignificant results, limitations should be considered to further improve mobile health app-based interventions such as SPA, as they could serve as reliable and convenient sources of support for parents.

Perinatal support for couples during COVID-19: A descriptive qualitative study.

AIMS AND OBJECTIVES: To explore the perspectives of parents during the perinatal period amid the COVID-19 pandemic and explore the experiences of Singaporean parents receiving perinatal support via the Supportive Parenting App (SPA). BACKGROUND: The stressors accompanying parenting responsibilities often affect the overall well-being of the family unit. With the emergence of the COVID-19 pandemic, Singaporean parents are forced to shoulder childcare responsibilities with minimal support due to safety restrictions. The Supportive Parenting Application (SPA) was introduced to parents during the start of the pandemic to offer timely additional support. It is a mobile health application-based educational support for parents across the perinatal period, consisting of features such as peer support, expert advice and discussion forums. DESIGN: Descriptive qualitative study. METHODS: Semi-structured one-to-one interviews were conducted with 33 parents (16 from the control group, 17 from the intervention group) in an ongoing randomised controlled trial between June 2021 and February 2022. The COREQ checklist was used to guide the reporting of the data. RESULTS: Four themes with 10 subthemes describing the perinatal experiences of parents were identified. The themes include 'Ups and downs' of parenting experiences; Perinatal care from 'best care' to 'flying blind'; What kept couples going and Use of technology-a way forward. CONCLUSION: Although COVID-19 negatively affected parents' availability of care and support, most could still access other support sources to help them. Additionally, the SPA was found to be a dependable information source for the intervention group parents. Future research could work on improving technology-based support based on the feedback given to offer better quality perinatal care for parents. RELEVANCE TO CLINICAL PRACTICE: Technology-based support provided by healthcare professionals helps provide reliable perinatal information and support for parents. More efforts should be directed towards developing quality informational resources and support to improve perinatal care. PATIENT OR PUBLIC CONTRIBUTION: Patients/members of the public contributed to the data collected and were involved in member checking to ensure the rigour of the study.

Cost-effectiveness of Web-Based and Home-Based Postnatal Psychoeducational Interventions for First-time Mothers: Economic Evaluation Alongside Randomized Controlled Trial.

BACKGROUND: The cost-effectiveness of interventions has attracted increasing interest among researchers. Although web-based and home-based psychoeducational interventions have been developed to improve first-time mothers' postnatal health outcomes, very limited studies have reported their cost-effectiveness. OBJECTIVE: The aim of this study was to evaluate the cost-effectiveness of web-based and home-based postnatal psychoeducational interventions for first-time mothers during the early postpartum period. METHODS: A randomized controlled 3-group pretest and posttest design was adopted, and cost-effectiveness analysis from the health care's perspective was conducted. A total of 204 primiparas were recruited from a public tertiary hospital in Singapore from October 2016 to August 2017 who were randomly allocated to the web-based intervention (n=68), home-based intervention (n=68), or control (n=68) groups. Outcomes of maternal parental self-efficacy, social support, postnatal depression, anxiety, and health care resource utilization were measured using valid and reliable instruments at baseline and at 1 month, 3 months, and 6 months after childbirth. The generalized linear regression models on effectiveness and cost were used to assess the incremental cost-effectiveness ratios of the web-based and home-based intervention programs compared to routine care. Projections of cumulative cost over 5 years incurred by the 3 programs at various coverage levels (ie, 10%, 50%, and 100%) were also estimated. RESULTS: The web-based intervention program dominated the other 2 programs (home-based program and routine care) with the least cost (adjusted costs of SGD 376.50, SGD 457.60, and SGD 417.90 for web-based, home-based, and control group, respectively; SGD 1=USD 0.75) and the best improvements in self-efficacy, social support, and psychological well-being. When considering the implementation of study programs over the next 5 years by multiplying the average cost per first-time mother by the estimated average number of first-time mothers in Singapore during the 5-year projection period, the web-based program was the least costly program at all 3 coverage levels. Based on the 100% coverage, the reduced total cost reached nearly SGD 7.1 million and SGD 11.3 million when compared to control and home-based programs at the end of the fifth year, respectively. CONCLUSIONS: The web-based approach was promisingly cost-effective to deliver the postnatal psychoeducational intervention to first-time mothers and could be adopted by hospitals as postnatal care support.

Non-steroidal anti-inflammatory drugs (NSAIDs) for trigger finger.

BACKGROUND: Trigger finger is a common hand condition that occurs when movement of a finger flexor tendon through the first annular (A1) pulley is impaired by degeneration, inflammation, and swelling. This causes pain and restricted movement of the affected finger. Non-surgical treatment options include activity modification, oral and topical non-steroidal anti-inflammatory drugs (NSAIDs), splinting, and local injections with anti-inflammatory drugs. OBJECTIVES: To review the benefits and harms of non-steroidal anti-inflammatory drugs (NSAIDs) versus placebo, glucocorticoids, or different NSAIDs administered by the same route for trigger finger. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, CNKI (China National Knowledge Infrastructure), ProQuest Dissertations and Theses, www.ClinicalTrials.gov, and the WHO trials portal until 30 September 2020. We applied no language or publication status restrictions. SELECTION CRITERIA: We searched for randomised controlled trials (RCTs) and quasi-randomised trials of adult participants with trigger finger that compared NSAIDs administered topically, orally, or by injection versus placebo, glucocorticoid, or different NSAIDs administered by the same route. DATA COLLECTION AND ANALYSIS: Two or more review authors independently screened the reports, extracted data, and assessed risk of bias and GRADE certainty of evidence. The seven major outcomes were resolution of trigger finger symptoms, persistent moderate or severe symptoms, recurrence of symptoms, total active range of finger motion, residual pain, patient satisfaction, and adverse events. Treatment effects were reported as risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs). MAIN RESULTS: Two RCTs conducted in an outpatient hospital setting were included (231 adult participants, mean age 58.6 years, 60% female, 95% to 100% moderate to severe disease). Both studies compared a single injection of a non-selective NSAID (12.5 mg diclofenac or 15.0 mg ketorolac) given at lower than normal doses with a single injection of a glucocorticoid (triamcinolone 20 mg or 5 mg), with maximum follow-up duration of 12 weeks or 24 weeks. In both studies, we detected risk of attrition and performance bias. One study also had risk of selection bias. The effects of treatment were sensitive to assumptions about missing outcomes. All seven outcomes were reported in one study, and five in the other. NSAID injection may offer little to no benefit over glucocorticoid injection, based on low- to very low-certainty evidence from two trials. Evidence was downgraded for bias and imprecision. There may be little to no difference between groups in resolution of symptoms at 12 to 24 weeks (34% with NSAIDs, 41% with glucocorticoids; absolute effect 7% lower, 95% confidence interval (CI) 16% lower to 5% higher; 2 studies, 231 participants; RR 0.83, 95% CI 0.62 to 1.11; low-certainty evidence). The rate of persistent moderate to severe symptoms may be higher at 12 to 24 weeks in the NSAIDs group (28%) compared to the glucocorticoid group (14%) (absolute effect 14% higher, 95% CI 2% to 33% higher; 2 studies, 231 participants; RR 2.03, 95% CI 1.19 to 3.46; low-certainty evidence). We are uncertain whether NSAIDs result in fewer recurrences at 12 to 24 weeks (1%) compared to glucocorticoid (21%) (absolute effect 20% lower, 95% CI 21% to 13% lower; 2 studies, 231 participants; RR 0.07, 95% CI 0.01 to 0.38; very low-certainty evidence). There may be little to no difference between groups in mean total active motion at 24 weeks (235 degrees with NSAIDs, 240 degrees with glucocorticoid) (absolute effect 5% lower, 95% CI 34.54% lower to 24.54% higher; 1 study, 99 participants; MD -5.00, 95% CI -34.54 to 24.54; low-certainty evidence). There may be little to no difference between groups in residual pain at 12 to 24 weeks (20% with NSAIDs, 24% with glucocorticoid) (absolute effect 4% lower, 95% CI 11% lower to 7% higher; 2 studies, 231 participants; RR 0.84, 95% CI 0.54 to 1.31; low-certainty evidence). There may be little to no difference between groups in participant-reported treatment success at 24 weeks (64% with NSAIDs, 68% with glucocorticoid) (absolute effect 4% lower, 95% CI 18% lower to 15% higher; 1 study, 121 participants; RR 0.95, 95% CI 0.74 to 1.23; low-certainty evidence). We are uncertain whether NSAID injection has an effect on adverse events at 12 to 24 weeks (1% with NSAIDs, 1% with glucocorticoid) (absolute effect 0% difference, 95% CI 2% lower to 3% higher; 2 studies, 231 participants; RR 2.00, 95% CI 0.19 to 21.42; very low-certainty evidence). AUTHORS' CONCLUSIONS: For adults with trigger finger, by 24 weeks' follow-up, results from two trials show that compared to glucocorticoid injection, NSAID injection offered little to no benefit in the treatment of trigger finger. Specifically, there was no difference in resolution, symptoms, recurrence, total active motion, residual pain, participant-reported treatment success, or adverse events.

Development of a Supportive Parenting App to Improve Parent and Infant Outcomes in the Perinatal Period: Development Study.

BACKGROUND: The transition to parenthood can be challenging, and parents are vulnerable to psychological disorders during the perinatal period. This may have adverse long-term consequences on a child's development. Given the rise in technology and parents' preferences for mobile health apps, a supportive mobile health intervention is optimal. However, there is a lack of a theoretical framework and technology-based perinatal educational intervention for couples with healthy infants. OBJECTIVE: The aim of this study is to describe the Supportive Parenting App (SPA) development procedure and highlight the challenges and lessons learned. METHODS: The SPA development procedure was guided by the information systems research framework, which emphasizes a nonlinear, iterative, and user-centered process involving 3 research cycles-the relevance cycle, design cycle, and rigor cycle. Treatment fidelity was ensured, and team cohesiveness was maintained using strategies from the Tuckman model of team development. RESULTS: In the relevance cycle, end-user requirements were identified through focus groups and interviews. In the rigor cycle, the user engagement pyramid and well-established theories (social cognitive theory proposed by Bandura and attachment theory proposed by Bowlby) were used to inform and justify the features of the artifact. In the design cycle, the admin portal was developed using Microsoft Visual Studio 2017, whereas the SPA, which ran on both iOS and Android, was developed using hybrid development tools. The SPA featured knowledge-based content, informational videos and audio clips, a discussion forum, chat groups, and a frequently asked questions and expert advice section. The intervention underwent iterative testing by a small group of new parents and research team members. Qualitative feedback was obtained for further app enhancements before official implementation. Testing revealed user and technological issues, such as web browser and app incompatibility, a lack of notifications for both administrators and users, and limited search engine capability. CONCLUSIONS: The information systems research framework documented the technical details of the SPA but did not take into consideration the interpersonal and real-life challenges. Ineffective communication between the health care research team and the app developers, limited resources, and the COVID-19 pandemic were the main challenges faced during content development. Quick adaptability, team cohesion, and hindsight budgeting are crucial for intervention development. Although the effectiveness of the SPA in improving parental and infant outcomes is currently unknown, this detailed intervention development study highlights the key aspects that need to be considered for future app development.

Prospective evaluation of the Ages and Stages Questionnaire 3rd Edition in very-low-birthweight infants.

AIM: To evaluate the predictive and concurrent diagnostic agreement of the Ages and Stages Questionnaire 3rd Edition (ASQ-3) with the Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III) in infants born preterm and very-low-birthweight (PT/VLBW; ≤1250g). METHOD: We evaluated 141 PT/VLBW infants (68 males, 73 females) born at the KK Women's and Children's Hospital between January 2010 and December 2011, to determine predictive and concurrent diagnostic agreement between the ASQ-3 at 9, 12, 18, and 24 months corrected age and Bayley-III at 24 months. Cut-offs on the ASQ-3 at 24 months were estimated by receiver operating characteristic curves. RESULTS: Sixty (43%) and 25 (18%) failed in any domain of the ASQ-3 and Bayley-III (<70) respectively. A negative predictive value (NPV) >98% was achieved for the motor domain from 9 months, and >90% for the communication domain and the overall results at 24 months. Optimal referral ASQ-3 score at 24 months to achieve 100% NPV was 243. INTERPRETATION: In PT/VLBW infants, ASQ-3 screening at 24 months can reduce the need for costly psychometric assessments in children with normal results. Clinicians can be assured of normal motor development at 9 months using the ASQ-3, but should continue to screen children on other domains.

Nutritional intake and growth velocity in preterm extremely low-birthweight infants in Asia: Are we doing enough?

AIM: To describe nutritional practices among preterm extremely low-birthweight (ELBW) infants and their impact on growth and to compare differences in nutritional intervention and comorbidities between those with limited growth velocity (GV < 25th percentile) and those with GV > 25th percentile. METHODS: A prospective cohort study was conducted to assess total protein and energy intake for week 1, days 14, 21 and 28 of life. Post-natal growth was calculated by measuring GV using an exponential model. Univariable analysis was applied to identify the potential risk factors associated with poor GV at day 28 and at discharge from hospital. RESULTS: The median GV from birth to day 28 was 9.84 g/kg/day and 11.87 g/kg/day for GV from birth to discharge. Increased protein and energy intake was associated with higher GV at discharge. Hypotension needing inotropes, necrotising enterocolitis (NEC), patent ductus arteriosus and chronic lung disease were significantly associated with reduced GV at discharge. Infants with NEC, hypotension needing inotropes and sepsis took a significantly longer time to achieve full enteral nutrition. A longer time to attain full enteral feeds was associated with slower GV at discharge. Small-for-gestational-age babies increased from 22% at birth to 66.6% at discharge. CONCLUSIONS: GV at discharge was positively correlated with increasing protein and energy intake in the first 28 days and adversely affected by the presence of neonatal morbidities. There was strong evidence of extra-uterine growth restriction, with the majority of preterm ELBW infants having lower z scores at discharge compared to at birth.

Cost-effectiveness analysis of liver resection versus transplantation for early hepatocellular carcinoma within the Milan criteria.

UNLABELLED: Both liver resection (LR) and cadaveric liver transplantation (CLT) are potentially curative treatments for patients with hepatocellular carcinoma (HCC) within the Milan criteria and with adequate liver function. Adopting either as a first-line therapy carries major cost and resource implications. The objective of this study was to estimate the relative cost-effectiveness of LR against CLT for patients with HCC within the Milan criteria using a decision analytic model. A Markov cohort model was developed to simulate a cohort of patients aged 55 years with HCC within the Milan criteria and Child-Pugh A/B cirrhosis, undergoing LR or CLT, and followed up over their remaining life expectancy. Analysis was performed in different geographical cost settings: the USA, Switzerland and Singapore. Transition probabilities were obtained from systematic literature reviews, supplemented by databases from Singapore and the Organ Procurement and Transplantation Network (USA). Utility and cost data were obtained from open sources. LR produced 3.9 quality-adjusted life years (QALYs) while CLT had an additional 1.4 QALYs. The incremental cost-effectiveness ratio (ICER) of CLT versus LR ranged from $111,821/QALY in Singapore to $156,300/QALY in Switzerland, and was above thresholds for cost-effectiveness in all three countries. Sensitivity analysis revealed that CLT-related 5-year cumulative survival, one-time cost of CLT, and post-LR 5-year cumulative recurrence rates were the most sensitive parameters in all cost scenarios. ICERs were reduced below threshold when CLT-related 5-year cumulative survival exceeded 84.9% and 87.6% in Singapore and the USA, respectively. For Switzerland, the ICER remained above the cost-effectiveness threshold regardless of the variations. CONCLUSION: In patients with HCC within the Milan criteria and Child-Pugh A/B cirrhosis, LR is more cost-effective than CLT across three different costing scenarios: the USA, Switzerland, Singapore.

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.

Real-World Data on the Diagnosis, Treatment, and Management of Hepatocellular Carcinoma in the Asia-Pacific: The INSIGHT Study.

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.

Evaluating the Effects of the Supportive Parenting App on Infant Developmental Outcomes: Longitudinal Study.

BACKGROUND: Previous studies have investigated the various effects of parenting on infant developmental outcomes. In particular, parental stress and social support have been found to significantly affect the growth of the newborn. Although many parents today use mobile apps to obtain more support in parenting and perinatal care, few studies have examined how these apps could affect infant development. OBJECTIVE: This study aimed to examine the effectiveness of the Supportive Parenting App (SPA) in improving infant developmental outcomes during the perinatal period. METHODS: This study adopted a 2-group parallel prospective longitudinal design and recruited 200 infants and their parents (N=400 mothers and fathers). The parents were recruited at 24 weeks of gestation for a randomized controlled trial conducted from February 2020 to July 2022. They were randomly allocated to either the intervention or control group. The infant outcome measures included cognition, language, motor skills, and social-emotional development. Data were collected from the infants when they were aged 2, 4, 6, 9, and 12 months. Linear and modified Poisson regressions were used to analyze the data to examine between- and within-group changes. RESULTS: At 9 and 12 months post partum, the infants in the intervention group were found to have better communication and language skills than those in the control group. An analysis of motor development revealed that a larger proportion of the infants in the control group fell under the at-risk category, where they scored approximately 2 SDs below the normative scores. The control group infants scored higher on the problem solving domain at 6 months post partum. However, at 12 months postpartum, the infants in the intervention group performed better on cognitive tasks than those in the control group. Despite not being statistically significant, the intervention group infants were found to have consistently scored better on the social components of the questionnaires than the control group infants. CONCLUSIONS: Overall, the infants whose parents had received the SPA intervention tended to fare better in most developmental outcome measures than those whose parents had received standard care only. The findings of this study suggest that the SPA intervention exerted positive effects on the communication, cognition, motor, and socioemotional development of the infants. Further research is needed to improve the content and support provided by the intervention to maximize the benefits gained by infants and their parents.

CREST: clinical bleeding and risk evaluation in hematology-oncology patients: a systematic review and meta-analysis of thromboelastography's role.

Thrombocytopenia and bleeding are common complications of hematologic malignancies. Often, prophylactic platelets are administered to minimize bleeding risk, based on total platelet count (TPC). However, TPC is a poor predictor, and does not provide rapid information. This review presents a novel prospective in the use of point-of-care viscoelastic studies to assess bleeding risk and guide transfusion therapy in a haematological oncological population, where its use can be extended to a ward level as a bedside test. Monitoring TEG maximum amplitude trends may be useful to guide transfusion protocols, especially for patients with total platelet counts ranging 30-100 × 10 9 /l. Fibrinogen assessment in this group of patients may identify other blood components that require replacing to reduce bleeding risk. Normal maximum amplitude parameters for patients with low platelet counts can be a reassuring sign. This meta-analysis serves to remind the reader that absolute platelet quantity does not equate to the quality of clot formation.

Prevalence of intracranial hemorrhage amongst patients presenting with out-of-hospital cardiac arrest: A systematic review and meta-analysis.

INTRODUCTION: An unknown proportion of out-of-hospital cardiac arrest (OHCA) is caused by intracranial hemorrhage (ICH). There is uncertainty over the role of early head computed tomography (CT) in non-traumatic OHCA due to uncertain diagnostic yield and ways to identify high-risk patients. This study aimed to identify the prevalence of ICH in non-traumatic OHCA and possible predictors. METHODS: PubMed, EMBASE, and the Cochrane library were searched from inception to January 2022. Data extraction and quality assessment were independently reviewed by two authors. Meta-analyses estimated the prevalence of ICH amongst OHCA patients and pre-specified subgroups and geographical settings. Subgroup analysis were used to explore potential clinical predictors. RESULTS: 23 studies involving 54,349 patients were included. The pooled ICH prevalence was 4.28% (95%CI: 3.31-5.24). Asia had a significantly larger risk ratio (RR = 3.93, P value < 0.0001) than Europe. The ICH subgroup was significantly more likely to be female (OR: 2.16; 95%CI: 1.10-4.26), and less likely to experience shockable rhythms compared with non-shockable rhythms (OR: 0.22; 95% CI: 0.04-1.22), achieve ROSC prior to arrival (OR: 0.27; 95%CI: 0.10-0.77), and survive to discharge compared to those without ICH (OR: 0.26; 95%CI: 0.11-0.59). CONCLUSIONS: One in twenty OHCA have ICH at the time of presentation. An early head CT scan should be strongly considered after return of spontaneous circulation (ROSC), especially in patients who are female, with non-shockable rhythm and did not attain ROSC prior to arrival. These finding should influence clinical protocols to favor routine scans especially in Asia where prevalence is higher.

A Systemic Review and Meta-analysis of Transabdominal Intravesical Prostatic Protrusion Assessment in Determining Bladder Outlet Obstruction and Unsuccessful Trial Without Catheter.

CONTEXT: Urodynamic study (UDS) provides the most objective assessment of bladder outlet obstruction (BOO) but is impractical to be recommended routinely in outpatient services. Intravesical prostatic protrusion (IPP) had been described to obstruct urinary flow by creating an anatomical ball-valve effect, but there remains a lack of pooled evidence that can objectively correlate with BOO in benign prostatic hyperplasia. OBJECTIVE: To update the current evidence on the predictive role of IPP in determining BOO and unsuccessful trial without catheter (TWOC). EVIDENCE ACQUISITION: A comprehensive literature search was performed to identify studies that evaluated IPP in diagnosing UDS-determined BOO and TWOC. The search included the PubMed/MEDLINE, EMBASE, and Cochrane Library up to January 2021. An updated systemic review and meta-analysis was performed. EVIDENCE SYNTHESIS: A total of 18 studies with 4128 patients were examined. Eleven studies with 1478 patients examined the role of IPP in UDS-determined BOO. The pooled area under the curve (AUC) was 0.83 (95% confidence interval [CI]: 0.79-0.86), and at a cut-off of >10 mm, the sensitivity (Sn) and specificity (Sp) were 0.71 (95% CI: 0.61-0.78) and 0.77 (95% CI: 0.68-0.84), respectively. The probability-modifying plot revealed positive and negative likelihood ratios of 3.34 (95% CI: 2.56-4.36) and 0.35 (95% CI: 0.26-0.45), respectively. Seven studies with 2650 patients examined IPP in predicting unsuccessful TWOC, with a pooled AUC of 0.74 (95% CI: 0.70-0.84), with Sn of 0.51 (95% CI: 0.43-0.60) and Sp of 0.79 (95% CI: 0.73-0.84) at an IPP cut-off of >10 mm. Five studies compared prostate volume (PV) and IPP and revealed a lower AUC of PV at 0.71 (95% CI: 0.67-0.75), which was an inferior parameter in diagnosing BOO (p < 0.001). CONCLUSIONS: This systemic review provided evidence that IPP is a reliable clinical parameter that correlates strongly with underlying BOO and unsuccessful TWOC. PATIENT SUMMARY: In this review, we comprehensively reviewed all the literature to date on evaluating the clinical utility of intravesical prostatic protrusion (IPP). We have demonstrated that IPP correlates strongly with urodynamic study (UDS)-determined bladder outlet obstruction and failure of trial without catheter (TWOC). Outpatient IPP measurement is a quick, inexpensive, and reproducible clinical parameter that can determine the severity of benign prostatic hyperplasia. The clinical role of IPP in predicting failure of TWOC selects patients who are best treated with aggressive surgical approaches rather than conservative medical therapies. More importantly, IPP can facilitate the discriminatory use of invasive UDS, reserved for patients with a strong suspicion of concomitant detrusor abnormalities.

Cost-Effectiveness of Drug-Coated Balloon Angioplasty Compared With Conventional Balloon Angioplasty for Arteriovenous Access Flow Dysfunction.

OBJECTIVES: This study aimed to determine the cost-effectiveness of drug-coated balloon (DCB) angioplasty compared with conventional balloon angioplasty (cPTA) in patients with arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs) dysfunction from a Singapore healthcare perspective. METHODS: Existing cost-effectiveness studies comparing DCB and cPTA have not incorporated AVF/AVG abandonment costs. This Markov model-based economic evaluation incorporated AVF/AVG creation and maturation costs on top of routine intervention costs to model a hypothetical cohort of 60-year-old AVF/AVG flow dysfunction patients. Effectiveness was measured in quality-adjusted life-years. Cost-effectiveness was assessed using incremental net monetary benefit (NMB) at a Singapore willingness-to-pay threshold of Singapore dollar (S$)87 000. Deterministic and probabilistic sensitivity analyses were performed to examine parameter uncertainty. To test hypotheses regarding cost-effectiveness, intervention counts per patient, cumulative incidence functions of AVF/AVG abandonment, and survival curves of death were compared between DCB and cPTA. RESULTS: DCB was not cost-effective at 3-year horizon (NMB = -S$1424), but was cost-effective at 1- and 6-year horizons (NMB = S$356 and S$3738, respectively). At 3 years, there was a 34.5% probability of DCB being cost-effective, but at 1- and 6-year horizons there was, respectively, 58.6% and 59.9% probability of DCB being cost-effective. DCB had graphically less AVF/AVG-abandonments, but this was not statistically significant (P = .21). Differences in other parameters were neither graphically nor statistically significant. CONCLUSIONS: With AVF/AVG abandonment considered, DCB may be weakly cost-effective compared with cPTA in treating AVF/AVG flow dysfunction. AV access creation and maturation costs could have important explanatory value in assessing DCB cost-effectiveness.

Early oral stepdown antibiotic therapy versus continuing intravenous therapy for uncomplicated Gram-negative bacteraemia (the INVEST trial): study protocol for a multicentre, randomised controlled, open-label, phase III, non-inferiority trial.

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.

11C-Metomidate PET-CT versus adrenal vein sampling to subtype primary aldosteronism: a prospective clinical trial.

OBJECTIVE: Adrenal vein sampling (AVS) is recommended to subtype primary aldosteronism, but it is technically challenging. We compared 11C-Metomidate-PET-computed tomography (PET-CT) and AVS for subtyping of primary aldosteronism. METHODS: Patients with confirmed primary aldosteronism underwent both AVS and 11C-Metomidate PET-CT (post-dexamethasone). All results were reviewed at a multidisciplinary meeting to decide on final subtype diagnosis. Primary outcome was accuracy of PET versus AVS to diagnosis of unilateral primary aldosteronism based on post-surgical biochemical cure. Secondary outcome was accuracy of both tests to final subtype diagnosis. RESULTS: All 25 patients recruited underwent PET and successful AVS (100%). Final diagnosis was unilateral in 22 patients, bilateral in two and indeterminate in one due to discordant lateralization. Twenty patients with unilateral primary aldosteronism underwent surgery, with 100% complete biochemical success, and 75% complete/partial clinical success. For the primary outcome, sensitivity of PET was 80% [95% confidence interval (95% CI): 56.3-94.3] and AVS was 75% (95% CI: 50.9-91.3). For the secondary outcome, sensitivity and specificity of PET was 81.9% (95% CI: 59.7-94.8) and 100% (95% CI: 15.8-100), and AVS was 68.2% (95% CI: 45.1-86.1) and 100% (95% CI: 15.8-100), respectively. Twelve out of 20 (60%) patients had both PET and AVS lateralization, four (20%) PET-only, three (15%) AVS-only, while one patient did not lateralize on PET or AVS. Post-surgery outcomes did not differ between patients identified by either test. CONCLUSION: In our pilot study, 11C-Metomidate PET-CT performed comparably to AVS, and this should be validated in larger studies. PET identified patients with unilateral primary aldosteronism missed on AVS, and these tests could be used together to identify more patients with unilateral primary aldosteronism.
