Abstract Metabolic Syndrome (MS) increases the risk for Coronary Artery Disease, stroke and diabetes. MS is twice more common amongst South Asian immigrants in US compared to native Caucasians. There are no nationally representative studies on prevalence of MS from any of the South Asian countries. The present study aims to evaluate the prevalence of MS among Sri Lankan adults and investigates its relationships with socio-demographic, clinical and biochemical parameters. Data on MS and its associated details were obtained from a population-based cross-sectional study conducted between years 2005–2006. MS was defined according to the International Diabetes Federation criteria. A binary logistic regression analysis was performed using the dichotomous variable MS (0 = absent, 1 = present). The independent co-variants were: gender, age category, area of residence, ethnicity, level of education, income and physical activity. Sample size was 4,485 (Response rate–89.7%), 39.5% were males and mean age was 46.1 ± 15.1 years. The crude prevalence of MS was 27.1% (95% CI: 25.8–28.5), and age-adjusted prevalence was 24.3% (95% CI: 23.0–25.6). Prevalence in males and females were 18.4% (95% CI: 16.5–20.3) and 28.3% (95% CI: 26.6–30.0) respectively (p 50,000 (OR:2.1), and physical inactivity (OR:1.6), all significantly increased risk of developing MS. MS is common among Sri Lankan adults affecting nearly one-fourth of the population. Female gender, increasing age, urban living, higher socio-economical status and physical inactivity were important associated factors.

Refractory hypothyroidism is associated with high morbidity and increased healthcare expenditure. In general, the use of the levothyroxine absorption test looks promising in evaluating refractory hypothyroidism but has shown significant variability in protocols in multiple settings. We intended to assess the usefulness of the levothyroxine absorption test in a low-resource setting and to assess the factors associated with refractory hypothyroidism. A cross-sectional study among age-matched 25 cases of refractory hypothyroidism and 24 treatment-responsive hypothyroid controls was conducted. A supervised levothyroxine absorption test was performed with levothyroxine 1000 μg tablets after a 10-h fast, and serum free tetraiodothyronine (FT4) levels were measured at 0, 1, 2, 3, 4, and 5 h. Descriptive statistics, chi-square test, Student's t-test, and logistic regression were used in the analysis. Results showed no significant difference in age, body weight, etiology of hypothyroidism, interfering medications, thyroxine storage, and ingestion technique in cases and controls. Cases had a longer duration of hypothyroidism and males had a higher peak FT4 concentration. During pooled analysis, serum FT4 peaked at 3 h with an increment of 149.4% (128.4-170.5%) from baseline and plateaued thereafter. The absolute value of FT4 at 3 h was 41.59 (s.d. 14.14) pmol/L (3.23 ng/dL). We concluded that there was no significant difference in the pattern of levothyroxine absorption in both groups. The most common cause of refractory disease was pseudo-malabsorption. Rapid supervised levothyroxine absorption test with two blood samples for FT4 at baseline and at the peak of absorption (3 h) is simple, convenient, and cost-effective, particularly in low-resource settings.

Background: There is a co-existence of different forms of malnutrition leading to a Triple Burden of Malnutrition (TBM) in Sri Lanka. Accessing basic needs and services was a challenge during COVID-19 pandemic, which led to issues in food security with an effect on nutrition status of the population., Objectives: To estimate the prevalence of malnutrition and dietary intakes of the population aged 1 to 60 years. Methods: This study was conducted in 2021. A multistage cluster sample was drawn to represent households at national level using 75 clusters, and 24-hour dietary recalls were compared with estimated average requirements of different age groups. Height and weight of all selected participants were measured., Results: A total of 1776 households and 2991 individuals were studied. The prevalence of wasting, stunting and overweight of children aged 1-4 years (n=486) was 14%, 16.3% and 0.8% respectively. Thinness, stunting, overweight and obesity of children aged 5-9 years (n=388) was 21.4%, 8.5%, 5.2%, 5.1%; children aged 10-17 years (n=355) was 21.1%, 14.1%,11%, 8.2%; and adults aged 18-60 years (n=1762) was 9.9%, 5.4%, 32.6% and 11.5% respectively. Dietary intake gaps were minimal with energy and protein while it was wider with majority of vitamins, iron and calcium. Stunting of children aged 1-4 years was significantly associated with the low calcium and iron intakes., Conclusions: The presence of TBM amongst children and adults were observed with a dietary gap of essential micronutrients. This study highlights the need to re-orient the nutritional interventions to control TBM at population level.

Objective: To compare length of stay (LOS) for paediatric patients receiving ketamine sedation or Bier's block anaesthesia for procedural closed fracture reduction., Methods: We conducted a retrospective audit of paediatric ED patients aged 3-18 years presenting at one of three metropolitan hospitals in Victoria, Australia (2012-2017). Outcomes were post-procedural LOS (PPLOS), total LOS, incidence of ketamine and Bier's block procedures, and recorded adverse effects. Groups were compared using t-tests. Association between treatment group and admission to a short stay unit (SSU) was assessed using univariate logistic regression., Results: Across all three sites, 449 patients were included, 379 of whom received ketamine sedation and 73 of whom underwent Bier's block anaesthesia. Mean age was 9.1 years (ketamine group: 8.3 years; Bier's block group: 13.1 years). Median PPLOS was 75 min shorter for patients who received a Bier's block than for those sedated with ketamine (P < 0.001). Patients sedated with ketamine were also 9.01 times more likely to be admitted to an SSU than those who received Bier's block anaesthesia (95% confidence interval 3.82-21.31, P < 0.001). Ketamine sedation was more common than Bier's block across the three sites. No major adverse events occurred in either group., Conclusion: Bier's block anaesthesia is a safe alternative to ketamine sedation for paediatric patients presenting to the ED with closed fractures. It is associated with reduced LOS and need for post-procedural observation. However, ketamine may remain preferable for younger paediatric patients, on whom it places fewer demands for cooperation., (© 2021 Australasian College for Emergency Medicine.)

Background: International labour migration continues to be an integral component in Sri Lanka's economic development. Previous research indicates an adverse perinatal outcome in association with low maternal pre-pregnancy body mass index (PBMI) and gestational weight gain (GWG). However, evidence of this association is limited in migrant families. This study aims to investigate the associations between PBMI, GWG among lactating mothers (LM), and fetal outcomes in migrant households, where the father is the migrant worker., Methods: A secondary data analysis was done using a nationally representative sample of 7,199 LM. There were 284 LM whose husbands were international migrant workers. Maternal factors were taken as PBMI<18.5 kg/m 2 and GWG<7kg. Preterm birth and low birth weight (LBW) were taken as fetal outcomes. Binary logistic regression was performed to assess the associated factors., Results: There was significant difference between LM from migrant and non-migrant households with regards to place of residency, ethnicity, household monthly income, household food security, average household members, husband's education and husband's age. Among migrant, PBMI<18.5 kg/m 2 was associated with current BMI and mode of delivery. Migrant LM had significantly higher weight gain (≥12 kg) during pregnancy (p=0.005), were multiparous (p=0.008), delivered in private hospital (p=0.000), lesser percentage of underweight (p=0.002) and higher birthweight (p=0.03) than non-migrant LM. Logistic regression model revealed that for each kilogram increment in birthweight and GWG, preterm delivery decreased by 89%(OR=0.11;95%CI:0.04-0.28) and LBW decreased by 12%(OR=0.89;95%CI:0.81-0.97) respectively. Caesarean deliveries were positively associated with low GWG., Conclusion: Our study showed LM in migrant families had invested remittances to utilize private health facilities for deliveries, to improve weight gain during pregnancy and adequate PBMI to deliver higher birth weight babies. In depth study is needed to understand further utilisation of remittances to improve fetal outcomes by increasing birthweight and GWG in migrant families., (© 2022. The Author(s).)

Background: Amiodarone is frequently used in emergency departments for treatment of arrhythmias. Incidence of several amiodarone-related adverse events is unknown. The literature is sparse for potentially life-threatening adverse effects of amiodarone., Case Report: We present a case of a male patient who presented with chest discomfort and rapid atrial fibrillation. He was known to have paroxysmal atrial fibrillation, which did not respond to initial beta-blocker treatment. The second-line drug amiodarone was given to the patient for rate control. He developed severe hypotension related to amiodarone and required inotropic support along with rapid-sequence intubation., Conclusions: Intravenous amiodarone can cause severe and refractory hypotension.

Objective: To evaluate patterns of physical activity (PA), the prevalence of physical inactivity and the relationships between PA and sociodemographic, clinical and biochemical parameters among Sri Lankan adults., Design: Descriptive cross-sectional study., Setting: Nationally representative population-based survey conducted in Sri Lanka., Subjects: Data on PA and associated details were obtained from 5000 adults. PA was assessed using the International Physical Activity Questionnaire (short-form). A binary logistic regression analysis was performed using the dichotomous variable ‘health-enhancing PA’ (05‘active’, 15‘inactive’)., Results: Sample size was 4485. Mean age was 46.1 (SD 15.1) years, 39.5% were males. The mean weekly total MET (metabolic equivalents of task) minutes of PA among the study population was 4703 (SD 4369). Males (5464 (SD 5452)) had a significantly higher weekly total MET minutes than females (4205 (SD 3394); P,0.001). Rural adults (5175 (SD 4583)) were significantly more active than urban adults (2956 (SD 2847); P<0.001). Tamils had the highest mean weekly total MET minutes among ethnicities. Those with tertiary education had lowest mean weekly total MET minutes. In all adults 60.0% were in the ‘highly active’ category, while only 11.0% were ‘inactive’ (males 14.6%, females 8.7%; P<0.001). Of the ‘highly active’ adults, 85.8% were residing in rural areas. Results of the binary logistic regression analysis indicated that female gender (OR52?1), age .70 years (OR53.8), urban living (OR52.5), Muslim ethnicity (OR52.7), tertiary education (OR53.6), obesity (OR51.8), diabetes (OR51.6), hypertension (OR51.2) and metabolic syndrome (OR51.3) were all associated with significantly increased odds of being physically ‘inactive’., Conclusions: The majority of Sri Lankan adults were ‘highly active’ physically. Female gender, older age, urban living, Muslim ethnicity and tertiary education were all significant predictors of physical inactivity. Physical inactivity was associated with obesity, diabetes, hypertension and metabolic syndrome.
