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

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

Bacterial communities of the threatened Western Pond Turtle may be impacted by land use.

As semi-aquatic species that use both terrestrial and aquatic habitats, freshwater turtles and their microbial communities are especially sensitive to the impacts of habitat disturbance. In this study, we use 16S rRNA amplicon sequencing to characterize the shell and cloacal bacterial communities of turtles in the San Francisco Bay Area. We captured western pond turtles (Actinemys/Emys marmorata) across eight sites located in urban and rural environments, along with invasive red-eared sliders (Trachemys scripta elegans). We assessed differences in western pond turtle bacterial communities diversity/composition between shell and cloacal samples and evaluated how alpha/beta diversity metrics were influenced by habitat quality. We found phylum-level bacterial taxonomic turnover in the bacterial communities of western pond turtles relative to the host tissue substrate samples. Our findings indicate that location identity elicits a high degree of lower-level (i.e. species/genus) bacterial taxonomic turnover. Further, we found that samples originating from good quality habitat had poorer shell bacterial communities but more diverse cloacal ones. The shell bacterial communities of red-eared sliders overlapped with those western pond turtles suggesting the existence of microbial dispersal between these two species. Our results add to our current understanding of turtle symbiont microbial ecology by establishing patterns of bacterial symbiont variation in an urban to rural gradient.

Restricted and repetitive behaviors and association with cognition and adaptive functioning in children with autism spectrum disorder in Singapore.

Background: One of the core features of autism spectrum disorder (ASD) is restricted, repetitive patterns of behavior, interests and activities (RRBs). RRBs are known to adversely affect cognition and adaptive functioning. We explored the relationship of RRBs with cognition and adaptive functioning in children with ASD in an Asian setting. Methods: This cross-sectional study was conducted at a tertiary developmental pediatrics center in Singapore from September 2019 to October 2021. Parent-child dyads (parents and their children ≤7 years old diagnosed with ASD) were recruited. Parents completed the Repetitive Behavior Questionnaire-2 (RBQ-2), which reports total score and two subscales - Motor/Sensory Behaviors (RBQ-2 MS) and Rigidity/Routines/Preoccupation with Restricted Interests (RBQ-2 RRPRI). Standardized assessments included Mullen Scales of Early Learning (MSEL) and Vineland Adaptive Behavior Scales (VABS-II). Data analysis utilized descriptive statistics and Pearson's correlation. Results: Parents of 113 children [75.2% male, mean (SD) age 5.0 (1.2) years] participated. Median (IQR) RBQ-2 score was 29.0 (11.0). Significant negative correlations (adjusted for age, gender and family history of ASD) were observed for total RBQ-2 scores with MSEL ELC scores (r = -0.248, n = 101, p = 0.014) and VABS-II ABC scores (r = -0.281, n = 88, p = 0.009). Specifically, these correlations of fair strength were seen only with the RBQ-2 MS subscale for both ELC (r = -0.321, n = 101, p = 0.001) and ABC (r = -0.3478, n = 88, p = 0.001). Conclusion: In children with ASD, severity of RRBs correlated with adverse cognition and adaptive functioning measures in our study, consistent with Western literature. While our study does not show causality, it adds to literature serving as a foundation for further research for both clinicians and researchers to target RRBs in improving outcomes with children in ASD.

Factors Contributing to Psychological Ill-Effects and Resilience of Caregivers of Children with Developmental Disabilities During a Nation-wide Lockdown During the COVID-19 Pandemic.

We evaluated factors affecting psychological ill-effects and resilience of caregivers of children with developmental disabilities during the coronavirus pandemic. Depression, Anxiety, and Stress Scales (DASS-21) and Connor-Davidson Resilience Scale 25-item were administered. Logistic regression was used to identify factors associated with psychological ill-effects and resilience. DASS-21 depression, anxiety and stress scores were high; these were associated with difficulties with infection control measures, autism diagnosis, and need for early intervention services. For caregivers of children with ASD, our DASS-21 scores were significantly higher than non-pandemic scores locally and in other Asian sites. Resilience scores correlated inversely with DASS-21 scores. Targeted support to selected at-risk caregivers and improving resilience can help their coping.

Early surgery after bridge-to-surgery stenting for malignant bowel obstruction is associated with better oncological outcomes.

BACKGROUND: Placement of self-expanding metal stents has been increasingly adopted as a bridge to surgery in patients presenting with obstructed left-sided colorectal cancers. The optimal bridging time has yet to be widely established, hence this retrospective study aims to determine the optimal bridging time to elective surgery post endoluminal stenting. PATIENTS AND METHODS: All patients who underwent colorectal stenting for large bowel obstruction in a single, tertiary hospital in Singapore between January 2003 and December 2017 were retrospectively identified. Patients' baseline demographics, tumour characteristics, stent-related complications, intra-operative details, post-operative complications and oncological outcomes were analysed. RESULTS: Of the 53 patients who successfully underwent colonic stenting for malignant left sided obstruction, 33.96% of patients underwent surgery within two weeks of stent placement while 66.04% of patients underwent surgery after 2 weeks of stent placement. Univariate analysis between both groups did not demonstrate significant differences in postoperative complications and stoma formation. Significant differences were observed between both groups for stent complications (38.89% vs 8.57%, p = 0.022), on-table decompression (38.89% vs 2.86%, p = 0.001) and systemic recurrence (11.11% vs 40.00%, p = 0.030). Increased bridging interval to surgery (OR 13.16, CI 1.37-126.96, p = 0.026) was a significant risk factor for systemic recurrence on multivariate analysis. CONCLUSIONS: Patients undergoing definitive surgery within 2 weeks of colonic stenting may have better oncological outcomes without compromising on postoperative outcomes. Further prospective studies are required to compare outcomes between emergency surgery and different bridging intervals.

Innovations in practice: Adaptation of developmental and behavioral pediatric service in a tertiary center in Singapore during the COVID-19 pandemic.

BACKGROUND: As the coronavirus 2019 pandemic continues, healthcare services need to adapt to continue providing optimal and safe services for patients. We detail our adaptive framework as a large Developmental and Behavioral Pediatrics service in a tertiary academic institution in Singapore. METHODS: The multidisciplinary team at our unit implemented various adaptations and workflow processes during this evolving pandemic in providing continued clinical care tailored to the challenges specific to our patient population. Services were continued via teleconsultation mode during the 'Circuit Breaker' (enhanced movement restriction) period. Specific workflow processes, IT infrastructure, and staff training were put in place to support smooth running of this service. Segregation of services into two teams based at two separate sites and implementation of stringent infection control measures surrounding the clinic visit by providers, patients and their families were incorporated to ensure safety. Measures were also taken to ensure providers' mental wellbeing. RESULTS: The clinical service was continued for the majority of our patients with a lowest reduction in patient consultations to half of baseline during the 'Circuit Breaker' period. We received positive feedback from families for teleconsultation services provided. CONCLUSION: We have been able to continue services in our DBP clinics due to our dynamic reassessment of workflow processes and their prompt implementation in conjunction with the hospital and national public health response to the pandemic. Given that this pandemic is likely to be long drawn, our unit remains ready to constantly adjust these workflows and make adaptations as we go along, together with the support for mental health of patients, parents and staff. Continual improvements in workflows will be helpful even beyond the pandemic to ensure good continuity of care for our patients and families.

Managing Children's Anxiety During COVID-19 Pandemic: Strategies for Providers and Caregivers.

The Coronavirus Disease 2019 pandemic by virtue of its sudden, unprecedented and widespread nature, has led to a multitude of psychological effects on individuals across societies. This includes anxiety which has important implications on the daily functioning, physical and mental health of individuals. Children are a vulnerable group of the population who can experience anxiety which potentially can lead to long-lasting implications on their health for years to come. It is thus important that their caregivers, including parents and healthcare professionals be aware of strategies that can help with anxiety in children. This article discusses anxiety in children in the context of the COVID-19 pandemic and outlines strategies that may be helpful.

Beyond Picky Eating.

CASE: Joseph is a 20-month-old boy who was thriving and developing well before a 4-day hospitalization for paralytic ileus at 11 months of age. Joseph is the first child born to parents who immigrated to the United States from Southeast Asia 3 years ago. Before the hospitalization, Joseph consumed 3 meals and 480 to 600 mL of milk daily. Oral feedings were restricted during the hospitalization with subsequent rejection of foods upon reintroduction of oral feeds. This resulted in 2 kg of weight loss by follow-up at 13 months. Joseph was referred to the multidisciplinary feeding and nutrition clinic at 16 months for failure to thrive, complicated by iron deficiency anemia and zinc deficiency. Joseph's feeding issues had negatively affected other aspects of his well-being; his development had stagnated, his sleep was fragmented (napping 5 times daily and frequent night waking attributed to hunger), and he had become withdrawn and irritable. By 16 months of age, Joseph was accepting only a couple of bites of solid foods by spoon or drinking small volumes (20-70 mL) of milk every 2 hours around the clock. Anthropometric z scores (World Health Organization) at 16 months: weight for age: < -3; length for age: -2.02; weight for length: -2.92; head circumference: -1.54. Physical examination revealed a cachectic and irritable child with loose skin folds. His skin was dry, and his hair was sparse. There were no perioral or perineal rashes, bruising, or features of rickets noted. Developmentally, parents reported that he was able to crawl and stand independently at the time of hospitalization, but by the time of evaluation at 16 months, he would no longer stand independently and tired quickly when crawling. He did not use any words but waved bye-bye, used gesture to indicate that he would like to be picked up, used a single-finger point to indicate his wants, and sought his parents for comfort. His fine motor skills were appropriate for chronological age. After extensive evaluation without findings of an organic cause for his failure to thrive, Joseph was diagnosed with avoidant restrictive food intake disorder (ARFID). Enteral nutrition was commenced using a nasogastric (NG) tube, and his micronutrient deficiencies were corrected. Joseph made significant gains within 2 weeks of beginning to receive enteral nutrition. Initial improvement in weight gain (25 g daily over 2 wk, resulting in weight for age z score improving to -1.85) was rapid. Joseph regained ability to stand and began taking a few independent steps. He also acquired the ability to use one word spontaneously and appropriately. His sleep improved, his previously cheerful disposition returned, and he became much easier to engage. Unfortunately, at 20 months, Joseph's parents chose to have the NG tube removed, and his growth began to falter. What would be your next steps in Joseph's care?

Parental concern of feeding difficulty predicts poor growth status in their child.

BACKGROUND: Parents often express concerns about feeding difficulties in their child. We hypothesized that these parental concerns were associated with adverse growth status in early childhood. We aimed to determine the prevalence of such concerns and whether these concerns were associated with adverse growth status in early childhood. METHODS: We performed a cross-sectional study among healthy children aged 12-36 months attending three well-baby clinics in three urban areas in Malaysia and Singapore between December 2016 and February 2017. Parents were interviewed for concerns about their child's feeding and presence of behavioral and organic red flags for feeding difficulties. We defined growth faltering as weight-for-age < 3rd centile and short stature as height-for-age < 3rd centile according to World Health Organization Growth Standards. RESULTS: Of the 303 children studied (boys = 160, 52.8%; mean [± SD] chronological age at interview 21.3 [± 4.0] months), 13% (n = 38/292) had growth faltering and 19.5% (n = 50/256) had short stature. Overall, 36.3% (n = 110) of parents expressed concerns about their child's feeding behavior. Sixty-eight percent (n = 206) of parents reported presence of at least one behavioral and 18.5% (n = 56) had at least one organic red flag for feeding difficulties, respectively. 9.9% (n = 30) had both behavioral and organic red flags for feeding difficulties. Growth faltering was significantly associated with parental concern about feeding (odds ratio [OR] 3.049, p < 0.001), food refusal (OR 4.047, p < 0.001) and presence of at least one organic red flag (OR 2.625, p = 0.012). CONCLUSION: We found that parental concerns about their child's feeding to be common. Presence of parental concern, food refusal in the child and presence of organic red flags for feeding difficulties are associated growth faltering in early childhood.

Exacerbation of Ventilation-Induced Lung Injury and Inflammation in Preterm Lambs by High-Dose Nanoparticles.

Mechanical ventilation of preterm neonates causes lung inflammation and injury, with potential life-long consequences. Inert 50-nm polystyrene nanoparticles (PS50G) reduce allergic inflammation in the lungs of adult mice. We aimed to confirm the anti-inflammatory effects of PS50G in a sheep asthma model, and investigate the effects of prophylactic administration of PS50G on ventilation-induced lung injury (VILI) in preterm lambs. We assessed lung inflammatory cell infiltration, with and without PS50G, after airway allergen challenge in ewes sensitised to house dust mite. Preterm lambs (0.83 gestation) were delivered by caesarean section for immediate tissue collection (n = 5) or ventilation either with (n = 6) or without (n = 5) prophylactic intra-tracheal administration of PS50G nanoparticles (3% in 2 ml). Ventilation was continued for a total of 2 h before tissue collection for histological and biomolecular assessment of lung injury and inflammation. In ewes with experimental asthma, PS50G decreased eosinophilic infiltration of the lungs. Ventilated preterm lambs showed molecular and histological signs of lung injury and inflammation, which were exacerbated in lambs that received PSG50G. PS50G treatment decreased established inflammation in the lungs of asthmatic sheep. However, prophylactic administration of PSG50 exacerbated ventilation-induced lung injury and lung inflammation in preterm lambs.

Differential short-term regional effects of early high dose erythropoietin on white matter in preterm lambs after mechanical ventilation.

Inadvertently injurious ventilation of preterm neonates in the delivery room can cause cerebral white matter (WM) inflammation and injury. We investigated the impact of an early high dose of recombinant human erythropoietin (EPO) on ventilation-induced WM changes in preterm lambs. Injurious ventilation, targeting a V(T) of 15 ml kg(-1) with no positive end-expiratory pressure, was initiated for 15 min in preterm lambs (0.85 gestation). Conventional ventilation was continued for a further 105 min. Lambs received either 5000 IU kg(-1) of EPO (EPREX®; Vent+EPO; n = 6) or vehicle (Vent; n = 8) via an umbilical vein at 4 ± 2 min. Markers of WM injury and inflammation were assessed using quantitative real-time PCR (qPCR) and immunohistochemistry and compared to a group of unventilated controls (UVC; n = 4). In Vent+EPO lambs compared to Vent lambs: (i) interleukin (IL)-1ß and IL-6 mRNA levels in the periventricular WM and IL-8 mRNA levels in the subcortical WM were higher (P < 0.05 for all); (ii) the density of microglia within the aggregations was not different in the periventricular WM and was lower in the subcortical WM (P = 0.001); (iii) the density of astrocytes was lower in the subcortical WM (P = 0.002); (iv) occludin and claudin-1 mRNA levels were higher in the periventricular WM (P < 0.02 for all) and (vi) the number of blood vessels with protein extravasation was lower (P < 0.05). Recombinant human EPO had variable regional effects within the WM when administered during injurious ventilation. The adverse short-term outcomes discourage the use of early high dose EPO administration in preterm ventilated babies.
