Article Synopsis
  • Induced hypothermia, a common treatment for hypoxic-ischemic encephalopathy (HIE), is less effective in South Asia despite the region having a high disease burden compared to high-income countries.
  • This study aimed to compare blood genome expression profiles of neonates with HIE from high-income countries (Italy) and low-income countries (India, Sri Lanka, and Bangladesh) to understand differences in outcomes.
  • The findings revealed variations in blood expression profiles at birth linked to adverse outcomes and highlighted differing responses to treatment in the two cohorts of neonates.

Background: Effect of duration of birth depression on neurodevelopmental outcomes in low- and middle-income countries (LMICs) is not known. We examined the association of birth depression with brain injury, neurodevelopmental outcomes, and hypothermia after hypoxic ischemic encephalopathy (HIE) in south Asia.

Methods: We compared cerebral magnetic resonance (MR) at 2 weeks, and adverse outcomes (death or moderate or severe disability) at 18 months in 408 babies with moderate or severe HIE who had long birth depression (positive pressure ventilation (PPV) >10 min or Apgar score<6 at 10 min or cord pH < 7.

Background: In recent years telehealth became a popular and a rational health service delivery approach, especially amidst multiple challenges posed while providing health care interventions during the COVID-19 pandemic.

Aim: We synthesized available evidence on telehealth for managing children with NDDs in the Asia-Pacific region with the aim of identifying successful methods.

Methodology: We systematically reviewed six electronic databases: MEDLINE, AMED, EMBASE, PsychInfo, Web of Science, and (CINAHL plus) using the keywords and database-specific subject headings from their inception to 25th August 2021.

Most children with autism spectrum disorder live in low- and middle-income countries. Most of them do not have access to timely and culturally acceptable interventions. Research from high-income countries and low- and middle-income countries, such as Sri Lanka, show that parent-mediated intervention programmes improve functional outcomes, highlighting the importance of parents as partners.

Article Synopsis
  • The study investigates the relationship between the place of birth (inborn vs. outborn) and the effectiveness of whole-body hypothermia in protecting against brain injury in neonates suffering from hypoxic-ischemic encephalopathy (HIE) in low- and middle-income countries.
  • Conducted in seven neonatal intensive care units across India, Sri Lanka, and Bangladesh, the research followed 408 neonates born after 36 weeks of gestation who were randomized into hypothermia and control groups, tracking various brain injury indicators over time.
  • Results indicate that inborn neonates were generally smaller and had different delivery methods compared to outborn neonates, raising questions about how birthplace impacts treatment outcomes for HIE in this demographic

Objectives: To describe the rehabilitation services available for communication disorders in Sri Lanka and to estimate the adequacy of the services in provinces and districts of the country.

Setting: The study considered government and private institutions, which provide rehabilitation services for communication disorders in Sri Lanka.

Participants: Institutions providing services of speech-language pathologists, audiologists and audiology technicians in Sri Lanka.

Introduction: The quality and the range of vocational training (VT) courses offered to youth with disabilities (YwD) in low-middle-income countries are underexplored. This protocol describes a study designed to gather perceptions of a range of stakeholders related to the quality and relevance of VT programmes conducted by the Department of Social Services in Sri Lanka. The purpose of this study is to communicate with authorities the ways in which they can improve their services by paying close attention to the needs and recommendations of all stakeholders.

Background: Although therapeutic hypothermia reduces death or disability after neonatal encephalopathy in high-income countries, its safety and efficacy in low-income and middle-income countries is unclear. We aimed to examine whether therapeutic hypothermia alongside optimal supportive intensive care reduces death or moderate or severe disability after neonatal encephalopathy in south Asia.

Methods: We did a multicountry open-label, randomised controlled trial in seven tertiary neonatal intensive care units in India, Sri Lanka, and Bangladesh.

Majority of under-five children with developmental disabilities live in low- and middle-income countries (LMIC). A considerable proportion of disabilities results from perinatal adversities. The neonatal and infant mortality rates in India, Bangladesh, and Sri Lanka have improved over the last two decades, implying survival of infants at risk for developmental impairments.

Introduction: Time-critical neonatal trials in low-and-middle-income countries (LMICs) raise several ethical issues. Using a qualitative-dominant mixed-methods design, we explored informed consent process in Hypothermia for encephalopathy in low and middle-income countries (HELIX) trial conducted in India, Sri Lanka and Bangladesh.

Methods: Term infants with neonatal encephalopathy, aged less than 6 hours, were randomly allocated to cooling therapy or usual care, following informed parental consent.

Objective: To assess the developmental progression and compare the developmental attainments of children treated with two hormonal therapies for infantile spasms (IS) over two years (seizure and EEG outcomes of this RCT published previously).

Methods: Newly diagnosed infants with IS were randomised to receive adrenocorticotrophin (ACTH) or prednisolone for 14 days. All underwent Bayley III Infant and Toddler Assessments in cognitive (Cog), receptive (RC) and expressive (EC) communication, fine (FM) and gross (GM) motor developmental subsets at baseline (T0), one-year (T1) and two-years (T2).

Introduction: Cerebral palsy (CP) describes a heterogeneous group of motor disorders resulting from disturbance in the developing brain. CP occurs in approximately 2.1 per 1000 live births in high-income countries, but in low- and middle-income countries (LMICs) the prevalence and severity of CP may be greater and aetiological risk factors different.

Aim: To describe the baseline developmental profile and influence of clinical and demographic factors on the developmental skills of infants diagnosed with infantile spasms.

Method: Ninety-five infants (55 males, 40 females) newly diagnosed with infantile spasms were recruited for a cross-sectional, longitudinal study. All infants underwent Bayley Scales of Infant and Toddler Development assessments in the cognitive, receptive communication, expressive communication, and fine and gross motor developmental domains; they also underwent visual, auditory, and social behaviour assessments.

Objective: We earlier completed a single-blind, parallel-group, randomized clinical trial to test the null hypothesis that adrenocorticotropic hormone (ACTH) is not superior to high-dose prednisolone for short-term control of West syndrome. We now present long-term follow-up data for spasm control for individuals who completed this earlier trial.

Methods: Infants with untreated West syndrome were randomized to receive 14 days of prednisolone (40 to 60 mg/day) or intramuscular long-acting ACTH (40 to 60 IU every other day).

Background: The role of therapy on improvement of hypsarrhythmia has not been systematically assessed. This study was performed to assess the efficacy of oral prednisolone and intramuscular adrenocorticotrophin hormone in improving hypsarrhythmia in West syndrome.

Method: Children (2 months-2 years), with previously untreated West syndrome, were randomized to receive 40-60 IU every other day of intramuscular adrenocorticotrophin hormone or 40-60 mg/day of oral prednisolone for 14 days.

Introduction: The final examination in paediatrics for medical undergraduates in Sri Lanka consists of a written and a clinical component. Each candidate at the clinical component sees one long case and two short cases.

Objectives: To assess the views of the bystanders regarding their sick children participating at a clinical examination, and to evaluate the children's perceptions of the clinical component.
