Primary health level screening for postpartum depression during well-child visits: Prevalence, associated risk factors, and breastfeeding.

Postpartum depression (PPD) is a public health problem that is associated with detrimental effects on the wellbeing of the mother, child and family. Early detection for PPD at the primary health level provides an opportunity for intervention. We aim to examine: (1) the prevalence rate of PPD in the primary care population, (2) acceptance and attendance rates of intervention for women who screened positive for PPD, (3) sociodemographic and maternal risk factors of PPD, and (4) the impact of PPD on breastfeeding. We implemented a mother-child dyadic screening program using the modified Patient Health Questionnaire-2 during routine well-child visits at 2 or 3 months postpartum between July 2019 and December 2021. We performed multivariable logistic regression to identify independent risk factors for PPD and described using adjusted odds ratio (OR) with corresponding 95 % confidence intervals. Among 5561 mothers, the prevalence rate of probable PPD was 2.4 %. About half (54.4 %) of mothers who screened positive accepted intervention and of these, about two-thirds accepted onward referrals to tertiary care and community mental health service, with higher attendance at the latter. In the final adjusted model, mothers who had probable PPD were more likely to be older than age 35 years (OR 1.88, 95 % CI 1.05-3.45; p < 0.05) and not breastfeeding (OR 1.9, 95 % CI 1.06-3.38; p < 0.05). Overall, our findings highlight the importance of early PPD screening and management in primary care. These findings can help inform maternal mental health service development and utilization, thereby optimizing maternal and infant outcomes.

Palliative and Critical Care: Their Convergence in the Pediatric Intensive Care Unit.

Palliative care (PC) is an integral component of optimal critical care (CC) practice for pediatric patients facing life-threatening illness. PC acts as an additional resource for patients and families as they navigate through critical illness. Although PC encompasses end of life care, it is most effective when integrated early alongside disease-directed and curative therapies. PC primarily focuses on improving quality of life for patients and families by anticipating, preventing and treating suffering throughout the continuum of illness. This includes addressing symptom distress and facilitating communication. Effective communication is vital to elicit value-based goals of care, and to guide parents through patient-focused and potentially difficult decision-making process which includes advanced care planning. A multidisciplinary approach is most favorable when providing support to both patient and family, whether it is from the psychosocial, practical, emotional, spiritual or cultural aspects. PC also ensures coordination and continuity of care across different care settings. Support for family carries on after death with grief and bereavement support. This narrative review aims to appraise the current evidence of integration of PC into pediatric CC and its impact on patient- and family-centered outcomes. We will also summarize the impact of integration of good PC into pediatric CC, including effective communication with families, advanced care planning, withholding or withdrawal of life sustaining measures and bereavement support. Finally, we will provide a framework on how best to integrate PC in PICU. These findings will provide insights on how PC can improve the quality of care of a critically ill child.

Novel two-tiered developmental screening programme for Singaporean toddlers: a quality improvement report.

Early identification of developmental delays with timely intervention, especially before the age of 3 years, can improve child development. In Singapore, however, diagnosis and intervention for developmental delays occur at a median age of 44 months. As early detection and intervention depends on an effective developmental screening programme, we aimed to improve the detection of developmental delays before the age of 3 years in a primary care setting. We did this by implementing a novel two-tiered screening programme which uses three standardised screening tools (Parents' Evaluation of Developmental Status, PEDS-Developmental Milestones and Ages and Stages Questionnaire-3). We used quality improvement methods to integrate and optimise this two-tiered programme into the existing 9-month and 18-month screening schedule, with an additional screening at 30 months to replace the pre-existing 36-month screening of the National Child Health Surveillance Programme. A total of three Plan-Do-Study-Act cycles were performed to ensure programme feasibility and sustainability. They focused on adequately training the primary care nurses, targeting an 80% screening rate and aiming for 20 min screening tool administration time per child. We assessed the proportion of children referred to the child development units after positive screening for developmental concerns under the new programme, with a pre-post and with-without intervention comparison, and reviewed the screening rates and screening tool administration time. The proportion of 18-month old children referred for developmental concerns improved from 3.5%-7.1% over a 6-month period. For those who received further assessment by developmental specialists after the two-tiered screening, 100% received a definitive diagnosis of developmental delays, similar to the situation before programme introduction. Our quality improvement efforts facilitated successful integration of the two-tiered programme into the pre-existing screening schedule with minimal impact to the clinic workflow. While we highlight challenges in implementation that need to be addressed, our findings support a potential nationwide adoption of the two-tiered programme.

Paediatric emergency department attendances during COVID-19 and SARS in Singapore.

INTRODUCTION: We evaluated the impact of public health measures on paediatric emergency department attendances during the COVID-19 and severe acute respiratory syndrome (SARS) outbreaks in Singapore. METHODS: Between 1 January 2020 and 31 July 2020, we retrospectively reviewed paediatric emergency department attendances and admissions in a tertiary paediatric hospital in Singapore before and after a national lockdown to combat the spread of COVID-19 in Singapore. Hospital attendances and admissions were compared with data from a corresponding period in 2019 (1 January 2019 to 31 July 2019), as well as during and after the SARS outbreak (1 January 2003 to 31 December 2004). RESULTS: Compared with a corresponding non-outbreak period, emergency department attendances decreased in line with nationwide public health measures during the COVID-19 and SARS outbreaks (2020 and 2003 respectively), before increasing gradually following lifting of restrictions, albeit not to recorded levels before these outbreaks. During the COVID-19 outbreak, mean daily attendances decreased by 40%, from 458 per day in January-July 2019, to 274 per day in January-July 2020. The absolute number of hospital inpatient admissions decreased by 37% from January-July 2019 (19,629) to January-July 2020 (12,304). The proportion of emergency department attendances requiring admission remained similar: 20% in January-July 2019 and 21% in January-July 2020. CONCLUSION: Nationwide public health measures in Singapore have had an impact on paediatric emergency department attendances and hospital inpatient admissions. Data from this study could inform planning and resource allocation for emergency departments in Singapore and internationally.

Optimal Dosing of Meropenem in a Small Cohort of Critically Ill Children Receiving Continuous Renal Replacement Therapy.

Severe sepsis is an important cause of mortality and morbidity in critically ill children. Meropenem is a broad-spectrum antibiotic commonly used to treat sepsis. Current meropenem dosage recommendations for children on continuous renal replacement therapy are extrapolated from pharmacokinetic (PK) studies done in adults. Our study aims to determine the optimal dosing in critically ill septic children receiving continuous renal replacement therapy. A prospective single-center PK study was performed in 9 children in the intensive care unit on continuous renal replacement therapy. Meropenem concentrations were measured from blood and effluent fluid samples. A population PK model was developed using nonlinear mixed-effects modeling software (NONMEM, AstraZeneca UK Ltd, Cheshire, UK). Monte Carlo simulations were performed. The PK/pharmacodynamic target aimed for plasma concentrations above minimum inhibitory concentration of 4 mg/L for 100% of dosing interval (100%ƒT>MIC ). A 2-compartment model best characterized meropenem PK. Mean (range) clearance and elimination half-life was 0.091 L/h/kg (0.04-0.157) and 3.9 hours (2.1-7.5), respectively. Dosing of 40 mg/kg/dose every 12 hours over 30 minutes achieved PK/PD target in only 32% while 20 mg/kg every 8 hours over 4 hours or 40 mg/kg every 8 hours over 2 hours achieved 100% ƒT>MIC target for at least 90% of simulated patients.

Novel Coronavirus 2019 Transmission Risk in Educational Settings.

Transmission risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in schools is unknown. Our investigations, especially in preschools, could not detect SARS-CoV-2 transmission despite screening of symptomatic and asymptomatic children. The data suggest that children are not the primary drivers of SARS-CoV-2 transmission in schools and could help inform exit strategies for lifting of lockdowns.

Impact of COVID-19 on pediatric emergencies and hospitalizations in Singapore.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has impacted the provision of health services in all specialties. We aim to study the impact of COVID-19 on the utilization of pediatric hospital services including emergency department (ED) attendances, hospitalizations, diagnostic categories and resource utilization in Singapore. METHODS: We performed a retrospective review of ED attendances and hospital admissions among children < 18 years old from January 1st to August 8th 2020 in a major pediatric hospital in Singapore. Data were analyzed in the following time periods: Pre-lockdown (divided by the change in Disease Outbreak Response System Condition (DORSCON) level), during-lockdown and post-lockdown. We presented the data using proportions and percentage change in mean counts per day with the corresponding 95% confidence intervals (CIs). RESULTS: We attended to 58,367 children with a mean age of 5.1 years (standard deviation, SD 4.6). The mean ED attendance decreased by 331 children/day during lockdown compared to baseline (p < 0.001), attributed largely to a drop in respiratory (% change - 87.9, 95% CI - 89.3 to - 86.3, p < 0.001) and gastrointestinal infections (% change - 72.4, 95%CI - 75.9 to - 68.4, p < 0.001). Trauma-related diagnoses decreased at a slower rate across the same periods (% change - 40.0, 95%CI - 44.3 to - 35.3, p < 0.001). We saw 226 children with child abuse, with a greater proportion of total attendance seen post-lockdown (79, 0.6%) compared to baseline (36, 0.2%) (p < 0.001). In terms of ED resource utilization, there was a decrease in the overall mean number of procedures performed per day during the lockdown compared to baseline, driven largely by a reduction in blood investigations (% change - 73.9, 95%CI - 75.9 to - 71.7, p < 0.001). CONCLUSIONS: We highlighted a significant decrease in infection-related presentations likely attributed to the lockdown and showed that the relative proportion of trauma-related attendances increased. By describing the impact of COVID-19 on health services, we report important trends that may provide guidance when planning resources for future pandemics.

Pharmacokinetics Alterations in Critically Ill Pediatric Patients on Extracorporeal Membrane Oxygenation: A Systematic Review.

Objectives: This study aimed to identify alterations in pharmacokinetics in children on extracorporeal membrane oxygenation (ECMO), identify knowledge gaps, and inform future pharmacology studies. Data Sources: We systematically searched the databases MEDLINE, CINAHL, and Embase from earliest publication until November 2018 using a controlled vocabulary and keywords related to "ECMO" and "pharmacokinetics," "pharmacology," "drug disposition," "dosing," and "pediatrics." Study Selection: Inclusion criteria were as follows: study population aged <18 years, supported on ECMO for any indications, received any medications while on ECMO, and reported pharmacokinetic data. Data Extraction: Clearance and/or volume of distribution values were extracted from included studies. Data Synthesis: Forty-one studies (total patients = 574) evaluating 23 drugs met the inclusion criteria. The most common drugs studied were antimicrobials (n = 13) and anticonvulsants (n = 3). Twenty-eight studies (68%) were conducted in children <1 year of age. Thirty-three studies (80%) were conducted without intra-study comparisons to non-ECMO controls. Increase in volume of distribution attributable to ECMO was demonstrated for nine (56%) drugs: cefotaxime, gentamicin, piperacillin/tazobactam, fluconazole, micafungin, levetiracetam, clonidine, midazolam, and sildenafil (range: 23-345% increase relative to non-ECMO controls), which may suggest the need for higher initial dosing. Decreased volume of distribution was reported for two drugs: acyclovir and ribavirin (50 and 69%, respectively). Decreased clearance was reported for gentamicin, ticarcillin/clavulanate, bumetanide, and ranitidine (range: 26-95% decrease relative to non-ECMO controls). Increased clearance was reported for caspofungin, micafungin, clonidine, midazolam, morphine, and sildenafil (range: 25-455% increase relative to non-ECMO controls). Conclusions: There were substantial pharmacokinetic alterations in 70% of drugs studied in children on ECMO. However, studies evaluating pharmacokinetic changes of many drug classes and those that allow direct comparisons between ECMO and non-ECMO patients are still lacking. Systematic evaluations of pharmacokinetic alterations of drugs on ECMO that incorporate multidrug opportunistic trials, physiologically based pharmacokinetic modeling, and other methods are necessary for definitive dose recommendations.

Household Transmission of Severe Acute Respiratory Syndrome Coronavirus 2 from Adults to Children.

Knowledge of transmission dynamics of severe acute respiratory syndrome coronavirus 2 from adults to children in household settings is limited. We found an attack rate among 213 children in 137 households to be 6.1% in households with confirmed adult 2019 novel coronavirus disease index case(s). Transmission from adult to child occurred in only 5.2% of households. Young children <5 years old were at lowest risk of infection (1.3%). Children were most likely to be infected if the household index case was the mother.

Approach to the snoring child.

Sleep is an important component in a child's growth and development. Snoring is common in children and often perceived as benign, but habitual snoring may be an indication of obstructive sleep apnoea (OSA). OSA can have health, developmental and cognitive consequences. The three common risk factors for paediatric OSA are tonsillar and/or adenoidal hypertrophy, obesity and allergic rhinitis. Primary care providers are well-placed to identify children at risk by screening for habitual snoring and associated OSA risk factors during routine consultations. Physician awareness of OSA symptoms/signs facilitates diagnosis, management and referral decisions. A trial of medical treatment may be considered for habitual snoring with mild symptoms/signs before referral. Overnight polysomnography is the gold standard investigation utilised by paediatric sleep specialists to diagnose OSA. Adenotonsillectomy is the first-line management for OSA with adenotonsillar hypertrophy, but residual/recurrent OSA may occur, so follow-up by primary care providers is important after surgery.

Epidemiology and Management of Children with Hypertensive Crisis: A Single-Center Experience.

Most children who present with hypertensive crisis have a secondary cause for hypertension. This study describes the epidemiology and management of children with hypertensive crisis. A retrospective cohort study was done in a tertiary pediatric hospital from 2009 to 2015. Thirty-seven patients were treated for hypertensive crisis. Twelve (32.4%) patients were treated for hypertensive emergency. The majority of our patients (33 [89.1%]) had a secondary cause of hypertension. The most common identifiable cause of hypertension was a renal pathology (18/37 [48.6%]). Oral nifedipine (23 [62.1%]) was the most frequently used antihypertensive, followed by intravenous labetalol (8 [21.6%]). There were no mortalities or morbidities. Hypertensive crisis in children is likely secondary in nature. Oral nifedipine and intravenous labetalol are both effective treatments.

Positive Fluid Balance is Associated with Poor Clinical Outcomes in Paediatric Severe Sepsis and Septic Shock.

INTRODUCTION: Growing evidence suggests there is potential harm associated with excess fluid in critically ill children. This study aimed to evaluate the association between percentage fluid overload (%FO) and paediatric intensive care unit (PICU) mortality in children with severe sepsis and septic shock. MATERIALS AND METHODS: Patients with severe sepsis and septic shock admitted to the PICU were identified through discharge codes. Data on clinical characteristics, fluid input and output were collected. %FO was calculated as: (total daily input - total daily output [L]/admission body weight [kg]) × 100. The primary outcome was PICU mortality. Secondary outcomes were 28-day ventilator-free days (VFD), intensive care unit-free days (IFD) and inotrope-free days (InoFD). Multivariate analysis adjusting for presence of comorbidities, Pediatric Index of Mortality (PIM) 2 score and multiorgan dysfunction were used to determine the association between cumulative %FO over 5 days and outcomes. RESULTS: A total of 116 patients were identified, with a mortality rate of 28.4% (33/116). Overall median age was 105.9 (23.1-157.2) months. Cumulative %FO over 5 days was higher in non-survivors compared to survivors (median [interquartile range], 15.1 [6.3-27.1] vs 3.6 [0.7-11.1]%; P <0.001). Cumulative %FO was associated with increased mortality (adjusted odds ratio 1.08, 95% confidence interval 1.03-1.13; P = 0.001) and decreased VFD, IFD and InoFD (adjusted mean difference -0.37 [-0.53 - -0.21] days, -0.34 [-0.49 - -0.20] days, and -0.31 [-0.48 - -0.14] days, respectively). CONCLUSION: Cumulative %FO within the first 5 days of PICU stay was consistently and independently associated with poor clinical outcomes in children with severe sepsis and septic shock. Future studies are needed to test the impact of restrictive fluid strategies in these children.

Caring for the mother-child dyad as a family physician.

Infant social, emotional and neurological development is shaped by the mother-child dyad. Dysfunction in this bond, as well as maternal mental health problems, can negatively impact child development. The family physician is well-placed to spot dysfunction in the mother-child dyad and screen for postnatal depression during well-child visits. If any issues are identified, the family physician can provide support and help the mother-child dyad to access community resources and specialist psychiatric services.

The Health and Well-Being of Caregivers of Technologically Dependent Children.

Caregivers of technology-dependent children face considerable responsibilities. This study examined the association of 2 child-related stressors-functional status and use of mechanical ventilator-with 2 domains of family caregiver well-being-depressive symptoms (Center for Epidemiologic Studies Depression Scale [CES-D]) and health-related quality of life (HRQOL) and family function (PedsQL Family Impact Module). The secondary objective was to determine whether these associations were moderated by caregiver-perceived social support. Structured interviews were conducted with 88 primary family caregivers of technology-dependent children in Singapore. Hierarchical multiple regression was used to assess the primary and secondary objectives. A total of 44.3% of caregivers were at high risk of clinical depression. Moderately poor child functional status was associated with more caregiver depressive symptoms. Perceived social support moderated this association. Family caregivers of technology-dependent children have high levels of depressive symptoms and relatively poor HRQOL and family functioning. Enhancing caregivers' social support is important for their well-being.

Nutritional practices and adequacy in children supported on extracorporeal membrane oxygenation.

BACKGROUND AND AIMS: Use of extracorporeal membrane oxygenation (ECMO) in children is increasing. Yet, little is known about optimal nutritional practices in these children. We aim to describe the nutritional adequacy, factors associated with enteral nutrition, and the association between nutritional adequacy and mortality in children supported on ECMO. METHODS: We conducted a retrospective review of all children (1 month-18 years) requiring ECMO between 2010 and 2016. Data on enteral and parenteral energy and protein intake in the first 7 days of ECMO were collected. Adequacy of nutrition intake was defined as total intake vs. total requirements, expressed as a percentage. RESULTS: 51 patients were included, of which 43 (84.3%) were supported on veno-arterial ECMO. Median ECMO duration was 8.6 days [interquartile range (IQR) 6.1-16.2]. Overall energy and protein adequacy across the first 7 days of ECMO were 48.3% (IQR 28.0-67.4) and 44.8% (IQR 26.9-67.0) respectively. Parenteral nutrition provided majority of calories [median 88.0% (IQR 62.9-100)] and protein [median 91.0% (IQR 62.3-100)] intake. Enteral nutrition (EN) was initiated in 33 (64.7%) patients. Time to EN initiation, vasoactive-inotropic score just before ECMO initiation, veno-arterial ECMO mode and continuous renal replacement therapy in the first week of ECMO were factors associated with EN energy adequacy. Hospital mortality rate was 55% (28/51). Compared to survivors, non-survivors had lower adequacy of EN energy intake [0.5% (IQR 0-4.4) vs. 11.8% (IQR 0-24.5), p = 0.034]. After correcting for ECMO duration, need for continuous renal replacement therapy and number of vasoactive drugs required on ECMO, greater EN energy adequacy remained associated with lower risk of mortality [adjusted odds ratio 0.93 (95% confidence interval: 0.86-0.99), p = 0.048]. CONCLUSIONS: Nutritional adequacy, especially that of EN, remains low in children supported on ECMO. EN energy adequacy was found to be associated with lower mortality. Further studies on nutritional adequacy in pediatric ECMO, as well as strategies to optimize EN in these children, are warranted.

Prevention of Acute Kidney Injury in Children Undergoing Cardiac Surgery: A Narrative Review.

Children undergoing cardiac surgery are at risk of developing acute kidney injury (AKI). Preventing cardiac surgery-associated AKI (CS-AKI) is important as it is associated with increased early- and long-term mortality and morbidity. Targeting modifiable risk factors (eg, avoiding poor renal perfusion, nephrotoxic drugs, and fluid overload) reduces the risk of CS-AKI. There is currently no strong evidence for the routine use of pharmacological approaches (eg, aminophylline, dexmedetomidine, fenoldopam, and steroids) to prevent CS-AKI. There is robust evidence to support the role of early peritoneal dialysis as a nonpharmacologic approach to prevent CS-AKI.

Singapore Paediatric Resuscitation Guidelines 2016.

We present the revised 2016 Singapore paediatric resuscitation guidelines. The International Liaison Committee on Resuscitation's Pediatric Taskforce Consensus Statements on Science and Treatment Recommendations, as well as the updated resuscitation guidelines from the American Heart Association and European Resuscitation Council released in October 2015, were debated and discussed by the workgroup. The final recommendations for the Singapore Paediatric Resuscitation Guidelines 2016 were derived after carefully reviewing the current available evidence in the literature and balancing it with local clinical practice.
