RESUMO
Caregivers are primarily responsible for the administration of Over The Counter (OTC) medications in children. This study examines the mothers' ability to determine and measure paracetamol doses for children aged between 1 and 5 years. A contrived observational study was conducted for mothers of preschool aged children at two Public Health Midwifery (PHM) areas in Southern province, Sri Lanka. Stratified random sampling was used. Only 26.9% (n = 95, 95% CI = 22.5%-31.7%) of the 353 participants correctly determined and measured the doses of paracetamol. Errors were frequently made in both determining and measuring dose together (n = 113, 32.0%, 95% CI = 27.3%-37.1%), determining only (n = 94, 26.6%, 95% CI = 22.2%-31.5%) and measurement only (n = 51, 14.4%, 95% CI = 11.1%-18.5%). Dose determined errors were not significantly associated with maternal education, number of children in the family, total monthly income and age of the index child. Similarly measuring errors were not significantly associated with mothers' education, income of the family and number of children in the family. However, there was a weak positive correlation between measuring errors and age of the index child. The study suggests that mothers made errors when determining doses and measuring doses of paracetamol. Results emphasize importance of clear, concise guardian information leaflet and healthcare professionals' guidance to minimize dosing errors of child medication.

OBJECTIVE: Adverse Drug Reactions (ADR) add a significant clinical and economic burden to the healthcare system of a country. We present an overview of the different approaches of ADR reporting systems worldwide and their evolution over time. METHODS: A systematic review of the literature was made based on PubMed and the Cochrane database of systematic reviews. The articles searched for included original articles, WHO and FDA reports and institute of medicine reports. Reporting ADRs is the cornerstone of detecting uncommon ADRs once the drugs are on the market. In many countries, ADR reporting is regulated by national regulatory bodies and various methods are employed to report ADRs. Direct reporting by healthcare professionals has been adopted by many developed and developing countries. With emerging new technologies in the field of medicine, there is a great potential to develop better ADR reporting systems in the countries where they have poor reporting. CONCLUSION: Development and acquisition of newer technologies to promote ADR monitoring and reporting is a necessity for an effective pharmacovigilance system in a country.

Pediatric renal injury is an emerging health concern in communities affected by chronic kidney disease of uncertain etiology (CKDu). Early detection of susceptibilities through highly sensitive and specific biomarkers can lead to effective therapeutic and preventive interventions against renal diseases. Here, we aimed to investigate the utility of kidney injury molecule (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) in early detection of renal abnormalities in selected pediatric communities in Sri Lanka. The study areas were stratified as CKDu endemic, emerging, and non-endemic based on the prevalence of CKDu, and a total of 804 school students (10-18 years of age) participated in the study. The median (IQR) urinary KIM-1 levels of the participants were 0.193 (0.026-0.338), 0.082 (0.001-0.220) and 0.040 (0.003-0.242) ng/mgCr for CKDu endemic, emerging and non-endemic regions respectively. Participants from CKDu endemic regions reported elevated (p < 0.0001) urinary KIM-1 expression compared to those from the other regions. The median (IQR) NGAL levels in participants from CKDu endemic (2.969; 1.833-5.641), emerging (3.374; 1.766-6.103), and non-endemic (3.345; 1.742-5.128 ng/mgCr) regions showed no significant difference. Also, urinary albumin-creatinine ratio (UACR) showed no significant differences across gender or residency. The prevalence of albuminuria was 1-2% in the locations irrespective of CKDu burden. Albuminuric participants reported higher (p < 0.05) urinary KIM-1 levels in comparison to normoalbuminuric participants. Significantly elevated urinary KIM-1 expression in a pediatric population from CKDu affected regions, especially in the presence of albuminuria, may indicate low-grade early renal damage supporting the utility of KIM-1 as a quantifiable biomarker.

Emerging renal biomarkers (e.g., kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL)) are thought to be highly sensitive in diagnosing renal injury. However, global data on reference intervals for emerging biomarkers in younger populations are lacking. Here, we aimed to determine reference intervals for KIM-1 and NGAL across a pediatric population in Sri Lanka; a country significantly impacted by the emergence of chronic kidney disease of unexplained etiology (CKDu). Urine samples were collected from children (10-18 years) with no prior record of renal diseases from the dry climatic zone of Sri Lanka (N = 909). Urinary KIM-1 and NGAL concentrations were determined using the enzyme-linked immunosorbent assay (ELISA) and adjusted to urinary creatinine. Biomarker levels were stratified by age and gender, and reference intervals derived with quantile regression (2.5th, 50th, and 97.5th quantiles) were expressed at 95% CI. The range of median reference intervals for urinary KIM-1 and NGAL in children were 0.081-0.426 ng/mg Cr, 2.966-4.850 ng/mg Cr for males, and 0.0780-0.5076 ng/mg Cr, 2.0850-3.4960 ng/mg Cr for females, respectively. Renal biomarkers showed weak correlations with age, gender, ACR, and BMI. Our findings provide reference intervals to facilitate screening to detect early renal damage, especially in rural communities that are impacted by CKDu.
RESUMO
Extensive use of herbicides is common among rural agricultural workers in Sri Lanka. Recent studies have postulated their role in the development of chronic kidney disease of unknown etiology (CKDu). Paraquat and glyphosate are leading herbicides used by sugarcane farmers (SF), hence occupational exposure is inevitable. This study examined the expression of urinary paraquat, glyphosate and biomarkers among residential SF in CKDu emerging regions, Warunagama (WA) and Rahathangama (RH), in the Uva Province with non-endemic Matara (MA) in the Southern Province of Sri Lanka. Urinary glyphosate, Paraquat, kidney injury molecule -1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL) and ß2-microglobulin (B2M) were determined using enzyme-linked immunosorbent assays (ELISA). Urinary creatinine, microalbumin, serum creatinine (SCr), serum cystatin C, estimated glomerular filtration rate (eGFR), and albumin creatinine ratio (ACR) were also assessed. Generally, herbicide residues and kidney injury biomarkers were higher in SF compared to the non-endemic MA. Creatinine-adjusted urinary glyphosate and paraquat levels were significantly higher in WA compared to MA. ACR in RH (median 14.9; IQR 5.4-393.1 mg/g) and WA (23.7; 11.5-64.6) was significantly higher than MA (4.3; 2.2-6.7). This study reports 39 individuals with impaired kidney function among SF in Sri Lanka for the first time. Urinary NGAL levels were significantly higher in both WA (median 2.14; IQR 1.28-6.15 ng/mg Cr) and RH (3.09; 1.15-9.09) compared to MA (1.28; 0.56-2.81). However, urinary KIM-1 levels in RH (3.2; 1.29-106.1 ng/g Cr) and WA (3.6; 1.94-115.1) were not significantly higher in MA (1.74; 0.76-116.9). Urinary NGAL (r = 0.493), eGFR (r = -0.147) and ACR (r = 0.171) significantly correlated with urinary glyphosate, but not with urinary paraquat levels. Urinary KIM-1 levels did not correlate with either urinary glyphosate or paraquat, while urinary B2M and serum cystatin C levels showed significant correlation with urinary glyphosate levels. The current study reports higher urinary herbicide levels among sugarcane farmers in WA and RH, and that is potentially linked to the subsequent decline in kidney function, as indicated by ACR, eGFR, and NGAL. We posit that these indicators may serve as markers to detect renal injury among herbicide-exposed SF in Rural Sri Lanka.

BACKGROUND: Chronic damage to the central nervous system resulting in cognitive impairment has been shown with repeated, low doses of organophosphorus (OP) exposure over month or years. AIM: The study aimed to find out whether there is any cognitive impairment following acute OP exposure that could be detected by a simple screening instrument, the Mini Mental State Examination (MMSE), in clinical settings. SETTINGS AND DESIGN: A cohort study. MATERIALS AND METHODS: The study was conducted with matched controls. Consecutive patients admitted to the hospital with acute ingestion of OP were recruited. Cognitive function was assessed with the MMSE, digit span test, test of long-term memory function and concentration. Patients were assessed twice: at 1 and 6 weeks of exposure. STATISTICAL ANALYSIS: Continuous variables were analyzed with the paired and unpaired T-tests. Non-normally distributed data were analyzed with the Mann-Whitney U test and Wilcoxon Signed Rank test. Discrete variables were analyzed with the Chi-square test. RESULTS: There were 60 patients and 61 controls. The mean age (SD) of the patients and controls was 31.5 (11.6) and 31.3 (11.8) years, respectively. Forty-two patients turned up for the second assessment. Significant impairment of cognitive function was seen in the total score of MMSE (95% CI -2.5 to -0.3), orientation (95% CI -1 to -0.2) and language (95% CI -0.9 to -0.1) domains of MMSE, digit span test (95% CI 0.1-1.7) and test of long-term memory function (95% CI 0.3-2.3) in the first assessment compared with the controls. When the results of the second assessment were compared with the controls, no significant differences were seen. CONCLUSION: Although there was a slight transient cognitive impairment detected with the screening tests following acute OP ingestion, no long-term cognitive defects was detected.

OBJECTIVE: To examine effects of pioglitazone (PIO) on systolic, diastolic, pulse and mean blood pressures (SBP, DBP, PP and MP, respectively) in type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: One hundred and six normotensive patients with T2DM with mean fasting blood glucose (FBS; 183 +/- 6 mg/dl) were randomly divided into two groups. Test group was treated with 15 mg of PIO in addition to metformin 500 mg three times per day in both groups. SBP, DBP, PP and MP and fasting insulin, FBS and lipid profiles were measured before and after PIO therapy. RESULTS: There was a significant reduction in SBP (123 +/- 2 vs. 118 +/- 2 mmHg, P < 0.05), PP (41 +/- 1 vs. 37 +/- 1 mmHg, P < 0.05), and MP (95 +/- 1 vs. 91 +/- 1, P < 0.05). Clinical reduction in DBP was observed but not significant (82 +/- 2 vs. 81 +/- 1 mmHg, P > 0.05). There was a significant correlation between decline in SBP and DBP with respective baseline values (r = 0.76, P < 0.001 and r = 0.62, P < 0.001, respectively). Changes in PP and MP strongly correlated with baseline values (r = 0.51, P < 0.05 and r = 0.56, P < 0.05, respectively). There was a parallel reduction of FBS (183 +/- 2 vs. 121 +/- 3, P < 0.001) but reduction in IR or lipid profiles was not significant in test group. Changes in BP were not significant in control group ( P > 0.05). CONCLUSION: PIO treatment of T2DM showed early reduction of SBP and MP within first 4 weeks. Results suggest that pharmacodynamic effects of PIO mainly affect the systolic component. We hereby suggest that reduction of BP by PIO is independent from mechanisms of changes in IR and dyslipidaemia in normotensive diabetic patients.
