Item 6379 Pre-admission management of children presenting with febrile illness in a tertiary hospital of Sri Lanka(BMJ, 2024) Arunath, V.; Mettananda, S.OBJECTIVES To describe the symptoms and pre-admission management of children presenting with febrile illness to the Colombo North Teaching Hospital, Ragama, Sri Lanka.METHODS A retrospective descriptive study was conducted at University Paediatric Unit of Colombo North Teaching Hospital, Ragama, Sri Lanka. Data on pre-admission management of all children admitted with febrile illness from July to December 2019 were extracted from patient records. Children who were transferred from other units, children with chronic illnesses and children developed fever following vaccinations were excluded. Ethical approval was obtained from Ethics Review Committee of Sri Lanka College of Paediatricians and data was analysed using SPSS version 22.RESULTS A total of 366 children were admitted; 56% were males. Mean age was 53.5 ± 41.7 months and the majority were from Gampaha district. Mean duration of illness on admission was 3.6 ± 2.5 days. 236 (65.6%) patients had recorded fever spikes at home while 150 (60.7%) reported a contact history of fever. Common associated symptoms were cough (62.3%), cold (56%) and vomiting (39.6%). 199 (54.5%) underwent investigations prior to admission and full blood count was the commonest (47.5%) investigation. Although 357 (97.8%) had taken medication prior to admission, only 87.3% had consulted a doctor. 356 (97.3%) received paracetamol at home of which 24 (7.9%) and 123 (40.6%) received sub-therapeutic and supra-therapeutic doses respectively. Significantly higher proportion (44.9%) of children who consulted a doctor received appropriate dose of paracetamol compared to others (3.7%), (c2=11.9, p=0.003, p<001). Higher proportion children who had recorded fever spikes consulted a doctor (c2=3.99, p=0.046, p<0.05) and received therapeutic doses of paracetamol prior to admission (c2=4.94, p=0.026, p<0.05).CONCLUSION Use of sub- and supra-therapeutic doses of paracetamol was common before admission to the hospital. Recording temperature at home and medical consultation prior to admission were associated with appropriate dose paracetamol usage (p<005).Item 6542 Clinical profiles of children less than 5 years presenting with or high risk of cerebral palsy in the Western Province of Sri Lanka(BMJ, 2024) Sumanasena, S.; Heiyanthuduwage, T.M.; Fernando, R.; Sheedy, H.S.; Jagoda, J.; Wijesekara, S.; Wanigasinghe, J.; Muttiah, N.; Rathnayake, P.; Kitnasamy, G.; Khandaker, G.OBJECTIVES Cerebral palsy (CP) is the commonest physical disability in children globally.1 It is a clinical diagnosis based on clinical and neurological findings. International clinical practice guidelines recommend early diagnosis and CP specific interventions to invest in neural plasticity and achieve optimal functional levels.2 In the past diagnosis was confirmed at 12–24 months but now it is advanced to confirm or identify as high risk for CP before the age of six months.3 4 Sri Lanka is one of the few Asian countries that initiated a CP register and National Guidelines on management of CP.5 The objective of this paper is to describe the clinical profiles of children less than 5 years presenting to Western Province hospitals in Sri Lanka based on the data from the Sri Lanka Cerebral Palsy Register (SLCPR).METHODS A cross sectional hospital-based study was conducted in the Western Province from September 2018 – October 2021 in three teaching hospitals to collect a minimum data set for the Sri Lanka SLCPR. Data of children less than 60 months was extracted with a confirmed clinical diagnosis of CP or identified formally as ‘high risk’ of CP.Information on sociodemographic, pre/peri/neonatal, and post neonatal risk factors, and associated impairments were collected using hospital records and clinic notes. Clinical motor type, topography, and associated impairments were evaluated.RESULTS Data of 431 children were extracted, 254 (58.9%) were males. Mean age at diagnosis was 28.73 months (median 27, SD 14.98). Most children (n= 422, 97.9%) acquired CP in the pre/peri/neonatal period. The mean birth weight was 2304.4 g (median 37, SD 825.58g) and the mean POA was 35.82 months (median 37, SD 4.88). Main risk factors identified were prematurity (n=190, 44.1%), hypoxic ischaemic encephalopathy (HIE) (n= 234, 54.3%), jaundice (n=31, 7.2%) and sepsis (n= 13, 3.0%). While 183 children (42.5%) showed evidence of definitive spastic motor type, 184 (42.7%) showed predominant dyskinesia.CONCLUSION The age at diagnosis of this population from Sri Lanka is significantly lower than from other LMICs. HIE and prematurity, both preventable conditions remain the highest risk factors. Longitudinal follow up will ascertain the final motor outcomes as a higher proportion of children showed dyskinesia. The SLCPR is an important resource which will support new research towards investigating opportunities for prevention and service planning for children.Item 6460 Children’s perception of the health effects of climate change – a mixed-method study in urban Sri Lanka(BMJ, 2024) Dayasiri, K.; Anand, G.OBJECTIVES While children bear the least responsibility for global climate change, they suffer the most from its consequences, including a higher incidence of non-communicable diseases and exposure to natural disasters. The United Nations has emphasised that failing to act on climate change infringes upon children’s rights to live in a secure environment. Our study focuses on examining the perspectives of Sri Lankan adolescents on climate change, its effects, and their roles in addressing this issue.METHODS This mixed-method cross-sectional study involved 104 adolescents attending schools in Colombo, Sri Lanka. We randomly selected participants from both governmental and private schools and invited them to complete a self-administered questionnaire. The questionnaire covered their perceptions of climate change, their contributions to addressing climate change, and their views on the regional and global implications of climate change. Qualitative data analysis was conducted using a second-order descriptive analysis of themes.RESULTS 104 adolescents participated in the study and 75.8% were female children. Median age =17 years (range 13–19 years). Majority (93.1%) expressed concern about the potential future health impacts of climate change. While most adolescents correctly understood the concept of climate change, some revealed misconceptions about it. The major health impacts associated with climate change, as reported by the participants, included asthma, the rise of non-communicable diseases, skin conditions, cancer, and increased stress. Notably, 25% of the participants felt that they had not received education on climate change. Nearly 60% reported feeling anxious over the issue of climate change. Regarding their contributions to addressing climate change, 29.8% of the children admitted that they had not taken sufficient actions. However, those who had acted mentioned activities such as tree planting, increased use of public transportation, and educating others about climate change. Almost half of the cohort were unaware of useful resources for learning about climate change. A significant 76% of the adolescents believed that adults were not actively taking measures to address climate change.CONCLUSION This study showed that children are evidently anxious over the issue of climate change. There is an urgent need for improved awareness of information sources among children through public health measures. It is essential for adults including those in the medical profession to serve as role models in educating and guiding children on how to make a positive impact on global climate change.Item Efficacy and safety of a novel low-dose triple single-pill combination compared with placebo for initial treatment of hypertension(Elsevier Biomedical, 2024) Rodgers, A.; Salam, A.; Schutte, A.E.; Cushman, W.C.; De Silva, H.A.; Tanna, G.L.D.; Grobbee, D.; Narkiewicz, K.; Ojji, D.B.; Poulter, N.R.; Schlaich, M.P.; Oparil, S.; Spiering, W.; Williams, B.; Jr, J.T.W.; Gutierez, A.; Sanni, A.; Lakshman, P.; McMullen, D.; Ranasinghe, G.; Gianacas, C.; Shanthakumar, M.; Liu, X.; Wang, N.; Whelton, P.BACKGROUND Single-pill combinations of 3 or more low-dose blood pressure (BP)-lowering drugs hold promise for initial or early treatment of hypertension.OBJECTIVES We conducted a placebo-controlled trial of a new single-pill combination containing low doses of telmisartan, amlodipine, and indapamide in 2 dose options to assess efficacy and safety.METHODS This international, randomized, double-blind, placebo-controlled, parallel-group trial enrolled adults with hypertension receiving 0 to 1 BP-lowering drugs. After a 2-week placebo run-in during which any BP-lowering medication was stopped, participants were eligible if home systolic BP (SBP) was 130 to 154 mm Hg. Participants were randomized in a 2:2:1 ratio to GMRx2 ¼ dose (telmisartan 10 mg/amlodipine 1.25 mg/indapamide 0.625 mg), GMRx2 ½ dose (telmisartan 20 mg/amlodipine 2.5 mg/indapamide 1.25 mg), or placebo. The primary efficacy outcome was difference in change in home SBP from randomization to week 4, and primary safety outcome was treatment discontinuation due to an adverse event.RESULTS From June 14, 2021 to October 18, 2023, a total of 295 participants (mean age: 51 years; 56% female) were randomized and 96% completed the trial. Baseline mean home BP was 139/86 mm Hg and clinic BP was 138/86 mm Hg after placebo run-in. The placebo-corrected least square mean differences in home SBP at Week 4 were -7.3 mm Hg (95% CI: -4.5 to -10.2) for GMRx2 ¼ dose and -8.2 mm Hg (95% CI: -5.2 to -11.3) for GMRx2 ½ dose; reductions for clinic BP were 8.0/4.0 and 9.5/4.9 mm Hg. At Week 4, clinic BP control (<140/90 mm Hg) was 37%, 65%, and 70% for placebo, GMRx2 ¼ dose, and GMRx2 ½ dose, respectively (both doses P < 0.001 vs placebo). Placebo, GMRx2-triple ¼, and GMRx2 ½ treatment discontinuation due to an adverse event occurred in 1 (1.6%), 0, and 6 (5.1%), respectively; out of normal range serum sodium or potassium was observed in 4 (6.3%), 12 (10.6%), and 12 (10.1%), respectively, but no participant had a serum sodium <130/>150 mmol/L or potassium <3.0/>6.0 mmol/L. Serious adverse events were reported by 2 participants in the placebo and GMRx2 ½ groups and none in the GMRx2 ¼ group.CONCLUSIONS In a population with mild-to-moderate BP elevation, both dose versions of the novel low-dose triple single-pill combination showed good tolerability and clinically relevant BP reductions compared with placebo.

Findings from the South Asia Biobank in four South Asian countrie(BMJ, 2024) Bhagtani, D.; Adams, J.; Imamura, F.; Lahiri, A.; Irfan, K.; Jha, V.; Kasturiratne, A.; Katulanda, P.; Mridha, M.; Anjana, R.M.BACKGROUND Escalation of ultra-processed foods (UPFs) sales has been recorded in low-to-middle-income countries, including in South Asia. However, individual consumption levels and sociodemographic characteristics influencing UPF consumption remain largely unknown in South Asia. We aimed to quantify UPF consumption and investigate its sociodemographic correlates in South Asia.METHODS We analysed data from 60,714 participants in the South Asia Biobank that recruited adults in Bangladesh, Pakistan, Sri Lanka, North India, and South India. Dietary assessment was conducted using interviewer-led 24h dietary recalls with a South Asia-specific digital tool. Foods were classified by the degree of industrial processing using the NOVA classification. Adjusted two-part multivariable regression models examined associations between sociodemographic factors and any UPF consumption and quantity of UPF consumption in consumers.RESULTS In Bangladesh, Sri Lanka and North India, approximately 75% of the participants reported consuming any UPFs in the previous 24h while in South India and Pakistan this was 40%. Median contribution of UPFs to total energy among UPF consumers ranged between 17% in Pakistan, 15% in North India, and 13% in Bangladesh, Sri Lanka, and South India. Biscuits were a common source of UPF across all regions. Other commonly consumed UPFs among consumers included sweetened beverages in Pakistan, packaged salty snacks in South India, and breakfast cereals in Bangladesh. Diverse associations between sociodemographic factors and any UPF consumption were seen across regions. Younger age was associated with any UPF consumption in Pakistan and Sri Lanka whereas in Bangladesh and North India, older age was. In all regions except Bangladesh, female sex was associated with any UPF consumption. Higher education was associated with UPF consumption in Bangladesh (odds ratio 2.01; 95% confidence interval 1.71 to 2.35), Pakistan (1.69; 1.55 to 1.85), and North India (1.40; 1.13 to 1.73). Paid employment was not associated with UPF consumption in any region. Among UPF consumers, in all regions, UPF consumption was lower in married or cohabitating than in single people. In Bangladesh and Sri Lanka UPF consumption was higher in rural residents, while in Pakistan, consumption was higher in urban participants.CONCLUSION Younger age, female sex, higher education, employment, and income exhibited associations with UPF, but this varied across South Asia. This heterogeneity should be considered when developing regionally specific interventions to support dietary public health. Our findings of regional consumption of specific UPFs, such as biscuits, breakfast cereals, sweetened beverages, and salty snacks, provide valuable insights for targeted interventions.Item 6503 Using anthropometric data to investigate the nutritional status of children included on the Sri Lankan cerebral palsy register.(BMJ Publishing Group Ltd, 2024) Sumanasena, S.; Fernando, R.; Kurukulaarachchi, S.; Heiyanthuduwage, T.M.; Sheedy, H.S.; Wijesekara, S.; Jagoda, J.; Muttiah, N.OBJECTIVES The nutritional data from children with cerebral palsy (CP) in low and middle income countries (LMIC) is sparse. In high income countries (HICs) well established nutritional care plans, commercial products and good psycho-social support are available.1 A multitude of complications arise due to malnutrition leading to poor quality of life.2 Here we investigated the nutritional status of children included in the Sri Lankan Cerebral Palsy Register (SLCPR).METHODS The study included 768 children aged 0–18 years with CP, attending three teaching hospitals in the Western Province, from September 2018 to November 2021. Data included clinical profile and anthropometry [weight (Kg), height (cm), BMI, mid upper arm circumference (MUAC) (cm), and OFC (cm)] based on WHO. Average was calculated using three repeated measurements. Children who could not stand independently (GMFCS level 4/5) underwent height estimations with the knee height equation: height = (2.69 X Knee height) + 24.2.Indicators used to measure the nutritional status were: weight for age Z score (WAZ), height for age Z score (HAZ), weight for height Z score (WHZ), BMI for age Z score (BAZ), and MUAC for age Z score (MUACZ). WHO Anthro and WHO AnthroPlus software calculated all Z scores.4 HAZ and BAZ were calculated for children aged <18 years, WAZ was calculated for children aged <10.1 years, and WHZ and MUACZ were calculated for children aged <5.1 years. The z scores < -2.0 SD were categorized as underweight (WAZ), stunted (HAZ), wasted (WHZ or MUAC), thin (BAZ).RESULTS Total of 768 children (mean age 59.6 months, SD 44.9, 62.5% males) participated. There were (n=431) children under 61 months and (n=520) from 0–10 years. Of them, 51.3% (n = 267/520) were underweight, 59.8% (n = 258/431) were stunted and 27.3% (n = 210/768) were thin. Among children aged < 5 years, 26.7% (n = 115/431) had severe wasting and severe acute malnutrition (SAM) according to MUACZ < -3SD. Both underweight and stunting were significantly higher among children with spastic CP compared with others (p<0.05). In the 5–19 year group 16.9% (n= 57/337) were obese (BAZ > + 2SD).CONCLUSION Predominant stunting and underweight in this population calls for urgent action to minimize chronic malnutrition. It is imperative to further explore nutritional intake and feeding difficulties in this group and offer structured nutritional care plans. The trend observed in older children towards obesity possibly indicates the need for coordinated nutrition and exercise programmes. It is recommended to regularly monitor growth and nutritional status of all children with CP as there may be serious implications for their activity levels.Item Predictors of response to electroconvulsive therapy in major depressive disorder: A review of research findings(Springer, 2024) Baminiwatta, A.; Menon, V.PURPOSE OF REVIEW In the context of the current global move towards precision medicine, considering the adverse effects, costs and efficacy limitations of electroconvulsive therapy (ECT) in major depression, this review aimed to identify predictors of ECT response based on recent research.RECENT FINDINGS Established predictors such as older age, psychotic symptoms, melancholic features, shorter episode duration, higher baseline severity, medication failure, and comorbid personality disorder were replicated in recent studies. Genetic polymorphisms showed little utility, whereas potentially useful epigenetic predictors were identified. Neurotrophic factors offer some predictive value. Some evidence for inflammatory markers emerged. Structural neuroimaging mainly implicates the hippocampal structures, amygdala, cingulate cortex, and other frontal lobe regions. Functional neuroimaging suggests an important role of brain functional connectivity, especially involving the default mode network.SUMMARY Many previously recognized demographic and clinical predictors of ECT response were supported, but evidence for biological predictors remains largely inconclusive, and requires further exploration and replication in future research.Item Characteristics and survival of advanced untreated hepatocellular carcinoma of non-viral etiology(Indian Society of Gastroenterology, 2024) Ekanayaka, S.P.N.; Luke, N.; Thilakarathne, S.B.; Dassanayake, A.; Gunetilleke, M.B.; Niriella, M.A.; Siriwardana, R.C.INTRODUCTION AND OBJECTIVES Hepatocellular carcinoma (HCC) is an aggressive tumor and presents late. The underlying etiology of HCC is changing rapidly. HCC in Sri Lanka is unique due to its predominant non-viral etiology (nvHCC) but lacks survival data.METHOD Data was collected from patients who presented with HCC from 2011 to 2018. There were 560/568 (98.6%) nvHCC. The patients who were not candidates for tumor-specific treatment (149/560 [26.7%]) were selected. Population characteristics, demographic data, tumor characteristics, survival and factors affecting survival were analyzed.RESULTS The median age was 64 years (range 30-88) and 86% (n = 129) were males. As many as 124 (83%) were cirrhotic. The overall performance score was 80%. Nearly 21/124 tumors were detected in cirrhotic screening. Tumors were single nodular in 32 (21%), up to three nodules in 28 (18%), more than three nodules in 33 (22%) and diffusely infiltrating in 56 (37%). The major venous invasions were present in 78 (52.3%). Extra-hepatic tumor spread was seen in 19 (12.7%) (lungs 13 [72.2%], bones 2 [11.1%]). The median survival of patients receiving palliative care was three months (1-43 months). Tumor size and cirrhotic status were significant predictors in univariate analysis.CONCLUSION A quarter of nvHCCs were not amenable to treatment at presentation as they had dismal survival.Item Navigating through 65 years of insights: lessons learned on functional abdominal pain in children(Springer Verlag, 2024) Rajindrajith, S.; Boey, C.C.M.; Devanarayana, N.M.; Niriella, M.A.; Thapar, N.; Benninga, M.A.In 1958, Apley and Naish authored a groundbreaking paper in Archives of Disease in Childhood, elucidating the epidemiology and risk factors of recurrent abdominal pain in children-a subject that had confounded clinicians of their time. Surprisingly, even after 65 years, there are several unanswered questions regarding the etiology, pathophysiology, and management of pediatric abdominal pain. Contrary to the prevailing notion that children naturally outgrow functional abdominal pain, compelling evidence suggests it's possible these children develop a number of clinically significant psychological issues that could profoundly impact their quality of life and, consequently, future health and educational outcomes. In this light, we aimed to comprehensively review the current literature to update the knowledge of practicing clinicians on functional abdominal pain, summarizing the evidence from the last 65 years.Conclusion: The enduring unanswered questions surrounding childhood abdominal pain continue to challenge clinicians, resulting in unnecessary investigations, thereby contributing to substantial healthcare expenditures. It is also evident that children with long-standing symptoms would progress to adulthood with the potential to develop irritable bowel syndrome and many psychological disturbances. Several key interventions using pharmacological agents, such as amitriptyline, showed that some of these drugs are no more effective than the placebo in clinical trials. Several research during the recent past suggest that psychological interventions such as gut-directed hypnotherapy alleviate symptoms and ensure better prognosis in the long run. Therefore, clinicians and researchers must join hands to explore the pathophysiological mechanisms underpinning functional abdominal pain and novel therapeutic strategies to ensure the well-being of these children. What is Known: • Functional abdominal pain disorders are common among children, with a worldwide prevalence of 13.5% of children suffering from at least one of these disorders • These disorders contribute to a significant reduction in the quality of life of affected children and their families and lead to an array of psychological problems What is New: • The biological basis of functional abdominal pain is becoming more explicit, including complex interactions between altered microbiome, deranged motility, and psychological dysfunction with gut-brain interactions • Novel approaches giving minimal emphasis on pharmacological interventions and exploring psychological interventions are showing promising results.Item A global survey on the use of the international classification of diseases codes for metabolic dysfunction-associated fatty liver disease(Springer, 2024) Zhang, H.; Targher, G.; Byrne, C.D.; Kim, S.U.; Wong, V.W.; Valenti, L.; Glickman, M.; Ponce, J.; Mantzoros, C.S.; Crespo, J.; Gronbaek, H.; Yang, W.; Eslam, M.; Wong, R.J.; Machado, M.V.; Yu, M.; Ghanem, O.M.; Okanoue, T.; Liu, J.; Lee, Y.; Xu, X.; Pan, Q.; Sui, M.; Lonardo, A.; Yilmaz, Y.; Zhu, L.; Moreno, C.; Miele, L.; Lupsor-Platon, M.; Zhao, L.; LaMasters, T.L.; Gish, R.G.; Zhang, H.; Nedelcu, M.; Chan, W.K.; Xia, M.; Bril, F.; Shi, J.; Datz, C.; Romeo, S.; Sun, J.; Liu, D.; Sookoian, S.; Mao, Y.; Méndez-Sánchez, N.; Wang, X.; Pyrsopoulos, N.T.; Fan, J.; Fouad, Y.; Sun, D.; Giannini, C.; Chai, J.; Xia, Z.; Jun, D.W.; Li, G.; Treeprasertsuk, S.; Li, Y.; Cheung, T.T.; Zhang, F.; Goh, G.B.; Furuhashi, M.; Seto, W.; Huang, H.; Sessa, A.D.; Li, Q.; Cholongitas, E.; Zhang, L.; Silveira, T.R.; Sebastiani, G.; Adams, L.A.; Chen, W.; Qi, X.; Rankovic, I.; Ledinghen, V.D.; Lv, W.; Hamaguchi, M.; Kassir, R.; Müller-Wieland, D.; Romero-Gomez, M.; Xu, Y.; Xu, Y.; Chen, S.; Kermansaravi, M.; Kuchay, M.S.; Lefere, S.; Parmar, C.; Lip, G.Y.H.; Liu, C.; Åberg, F.; Lau, G.; George, J.; Sarin, S.K.; Zhou, J.; Zheng, M.; Niriella, M.A. (MAFLD ICD-11 coding collaborators)BACKGROUND With the implementation of the 11th edition of the International Classification of Diseases (ICD-11) and the publication of the metabolic dysfunction-associated fatty liver disease (MAFLD) nomenclature in 2020, it is important to establish consensus for the coding of MAFLD in ICD-11. This will inform subsequent revisions of ICD-11.METHODS Using the Qualtrics XM and WJX platforms, questionnaires were sent online to MAFLD-ICD-11 coding collaborators, authors of papers, and relevant association members.RESULTS A total of 890 international experts in various fields from 61 countries responded to the survey. We also achieved full coverage of provincial-level administrative regions in China. 77.1% of respondents agreed that MAFLD should be represented in ICD-11 by updating NAFLD, with no significant regional differences (77.3% in Asia and 76.6% in non-Asia, p = 0.819). Over 80% of respondents agreed or somewhat agreed with the need to assign specific codes for progressive stages of MAFLD (i.e. steatohepatitis) (92.2%), MAFLD combined with comorbidities (84.1%), or MAFLD subtypes (i.e., lean, overweight/obese, and diabetic) (86.1%).CONCLUSIONS This global survey by a collaborative panel of clinical, coding, health management and policy experts, indicates agreement that MAFLD should be coded in ICD-11. The data serves as a foundation for corresponding adjustments in the ICD-11 revision.
