    (Faculty of Medicine, University of Kelaniya, Sri Lanka, 2021) Dharamarathna, N.D.; Samarasekara, D.; Madubhashin, D.; Rupasena, S.; Rajapaksha, N.; Sansala, T.
    Introduction: Individuals who seek inpatient hospital care due to COVID 19 infection are drastically increasing and nurses are crucial in caring for patients. Proper awareness and positive attitudes are the key pillars for pertinent caring of patients with COVID 19. Objectives: The study aimed to evaluate the awareness and attitudes towards COVID- 19 among nursing officers of National Institute of Mental Health (NIMH), Sri Lanka. Methods: A descriptive cross-sectional study was conducted among randomly selected 201 nurses of NIMH. A pretested self-administered questionnaire was used to collect data. Data were analysed using descriptive statistics and Pearson chi-square test. Overall awareness was categorised using modified Bloom’s cut-off point as good (80%-100%), moderate (50%-79%), and poor (< 50%). Results: The majority were female (92%) with a mean age of 31±6 years. Of participants, 40% reported a history of exposure to COVID 19 while 27% had quarantine. Nearly half of the participants (52%) had moderate awareness with a mean of 70±14 (range 20-90). Referring the COVID 19 guidelines (p=0.001) and working experience (p=0.04) was significantly associated with the awareness. The mean value of the attitudes was 61 ±6 (range 46-80) and 63% (n=127) had a neutral attitude towards COVID-19. Working in a medical ward (p=0.01) or COVID suspected ward (p=0.005) and experience of quarantine (p=0.01) were significantly associated with attitudes. Conclusions: Overall awareness and attitudes were at a moderate level among most. It is necessary to take measures to enhance the knowledge and attitudes towards COVID 19 among nurses.

    Prevalence of inflammatory bowel disease in two districts of Sri Lanka: a hospital based survey
    (BioMed Central, 2010) Niriella, M.A.; de Silva, A.P.; Dayaratne, A.H.G.K.; Ariyasinghe, M.H.A.D.P.; Navarathne, M.M.N.; Peiris, R.S.K.; Samarasekara, D.; Satarasinghe, R.L.; Rajindrajith, S.; Dassanayake, A.S.; Wickremasinghe, A.R.; de Silva, H.J.
    BACKGROUND: Inflammatory bowel disease (IBD) is being increasingly diagnosed in Asia. However there are few epidemiological data from the region. METHODS: To determine prevalence and clinical characteristics of IBD, a hospital-based survey was performed in the Colombo and Gampaha districts (combined population 4.5 million) in Sri Lanka. Patients with established ulcerative colitis (UC) and Crohn's disease (CD), who were permanent residents of these adjoining districts, were recruited from hospital registries and out-patient clinics. Clinical information was obtained from medical records and patient interviews. RESULTS: There were 295 cases of IBD (UC = 240, CD = 55), of which 34 (UC = 30, CD = 4) were newly diagnosed during the study year. The prevalence rate for UC was 5.3/100,000 (95% CI 5.0-5.6/100,000), and CD was 1.2/100,000 (95% CI 1.0-1.4/100,000). The incidence rates were 0.69/100,000 (95% CI 0.44-0.94/100,000) for UC and 0.09/100,000 (95% CI 0.002-0.18/100,000) for CD. Female:male ratios were 1.5 for UC and 1.0 for CD. Mean age at diagnosis was (males and females) 36.6 and 38.1y for UC and 33.4 and 36.2y for CD. Among UC patients, 51.1% had proctitis and at presentation 58.4% had mild disease. 80% of CD patients had only large bowel involvement. Few patients had undergone surgery. CONCLUSIONS: The prevalence of IBD in this population was low compared to Western populations, but similar to some in Asia. There was a female preponderance for UC. UC was mainly mild, distal or left-sided, while CD mainly involved the large bowel.
