Item Identification of type 2 diabetes patients with non-alcoholic fatty liver disease who are at increased risk of significant hepatic fibrosis: a cross-sectional study(Sri Lanka Medical Association, 2023) Mettananda, K.C.D.; Egodage, T.; Dantanarayana, C.; Solangarachchi, M.B.; Fernando, R.; Ranaweera, L.; Siriwardhena, S.; Ranawaka, C.K.; Kottahachchi, D.; Pathmeswaran, A.; Dassanayake, A.S.; de Silva, H.J.INTRODUCTION: Annual screening of patients with diabetes for fatty liver, and identifying those with significant hepatic fibrosis using the FIB-4 score and vibration-controlled transient elastography (VCTE) has been recommended to detect patients who may progress to advanced hepatic fibrosis/cirrhosis. However, VCTE is not freely available in resource-limited settings. OBJECTIVES: To identify clinical and biochemical predictors of significant liver fibrosis in diabetics with fatty liver. METHODS: We conducted a cross-sectional study among all consenting adults with T2DM and non-alcoholic fatty liver disease (NAFLD) attending the Colombo North Teaching Hospital, Ragama, Sri Lanka from November 2021 to November 2022. FIB-4 scores were calculated and patients with a score ≥1.3 underwent VCTE. Risk associations for liver fibrosis were identified by comparing patients with significant fibrosis (LSM ≥8 kPa) with those without significant fibrosis (FIB-4<1.3). RESULTS: A total of 363 persons were investigated. Of these, 243 had a score of FIB-4 <1.3. Of the 120 with a FIB-4 ≥1.3, 76 had LSM ≥8 kPa. Significant fibrosis was individually associated with age (OR 1.01, p<0.0001), duration of diabetes (OR 1.02, p=0.006), family history of liver disease (OR 1.42, p=0.035), waist (OR 1.04, p=0.035), and FIB-4 (OR 2.08, p<0.0001). However, on adjusted analysis, significant fibrosis was only associated with a family history of liver disease (OR 2.69, p=0.044) and FIB-4 (OR 1.43, p<0.001). CONCLUSION: In patients with T2DM and fatty liver, advancing age, increased duration of diabetes, a family history of liver disease, waist circumference and a high FIB-4 score increase the risk of significant hepatic fibrosis. Targeted interventions in this group may help prevent progression to advanced hepatic fibrosis/cirrhosis.Item Development and assessment of psychometric properties of model medication adherence (MMA) questionnaire to measure adherence to oral medication among patients with type 2 diabetes mellitus(College of Community Physicians of Sri Lanka, 2023) Perera, S.; Abeysena, C.INTRODUCTION: Medication adherence among patients with type 2 diabetes (DM) is assessed in everyday clinical practice. OBJECTIVES: To develop a questionnaire to measure adherence to oral medication among patients with DM and to assess its psychometric properties METHODS: The “Model Medication Adherence (MMA)” questionnaire was developed using the evidence from literature review and interviews with key stakeholders and patients. Answers were set on a five-point Likert scale that scored from 1 to 5, with 15-73 as the possible range of the total score. MMA was drafted in English and translated to Sinhala language by forward- backward translation. A descriptive cross-sectional study was carried out among adult patients with type 2 DM who attended clinics in Gampaha District General Hospital (DGH). A sample of 150 patients was recruited consecutively. The construct validity of MMA was assessed by Exploratory Factor Analysis (EFA) through Principal Component Analysis (PCA) with Varimax rotation RESULTS: EFA yielded four factors; sick role behaviour, autonomy, forgetfulness, and barriers that explained 64.36% of the variance of the total score of MMA. Internal consistency was acceptable (Cronbach’s alpha 0.73). The testretest reliability coefficient was 0.85 (p=0.01). Acceptability of the MMA was established by non-response items (none) and the time taken to complete (20 minutes). CONCLUSIONS & RECOMMENDATIONS: MMA is a simple valid questionnaire that adds a novel concept to the adherence literature; sick role and autonomy. It has a good factor structure with established construct validity and is recommended to be used in the clinical setting.Item Glucose tolerance(Intech, 2012) Chackrewarthy, S.The progression from normal glucose tolerance (NGT) to type 2 diabetes involves intermediate stages of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), also known as prediabetes. The pathophysiology underlying the development of these glucose metabolic alterations is multifactorial, leading to an alteration in the balance between insulin sensitivity and insulin secretion. Our knowledge of the molecular basis of the signaling pathways mediating the various physiologic effects of insulin is steadily advancing. New substrates and signaling molecules have been identified and potential mechanisms involved in the pathophysiology of type 2 diabetes have been revealed. This book summarises the current state of knowledge on the pathophysiology underlying the progression from normal glucose tolerance to type 2 diabetes and therapeutic advances in the improvement of glycaemic control in prediabetic and diabetic states.Item Hypoglycaemic and hypolipidaemic effects of an ethylacetate fraction of Artocarpus heterophyllus leaves(Intech, 2012) Chackrewarthy, S.; Thabrew, M.I.
