RESUMO
BACKGROUND: Acute coronary syndrome (ACS) is a type of coronary heart disease (CHD), which is responsible for one-third of total deaths in people older than 35 years. Even though cardiac troponin is the gold standard for myocardial necrosis it is blind for ischemia without necrosis. Studies demonstrate that Ischaemia Modified Albumin (IMA) is more sensitive in diagnosing ischemic chest pain compared to cardiac troponin T and electrocardiogram, and its combination with these tests significantly increases the sensitivity for diagnosing unstable angina, non-ST-elevation myocardial infarction (NSTEMI), or ST-elevation myocardial infarction (STEMI), with high positive and negative predictive values, making it a valuable tool for ruling out ACS in patients with inconclusive diagnoses in the emergency department. METHODS: This prospective cohort study, conducted at the Teaching Hospital, Peradeniya, Sri Lanka, from 2015 to 2019, investigated ischemia-modified albumin (IMA) levels in 330 acute coronary syndrome (ACS) patients. Excluding those with various chronic conditions and those on specific medications, serum IMA was analyzed using a colorimetric assay based on cobalt (II) binding to human serum albumin affected by myocardial ischemia. Serum IMA levels were measured, and statistical analyses, including non-parametric tests and correlation analyses, were conducted to evaluate the association between IMA levels and various demographic and clinical factors. RESULTS: IMA concentrations were found to be non-normally distributed, with an average concentration of 0.252 ± 0.123 AU. No overall significant gender-based difference in IMA levels was observed, though within the younger age group (< 59 years), males exhibited higher IMA concentrations than females. Significant gender differences were observed in the younger age group, with males showing higher IMA levels than females (p = 0.033). No significant differences in IMA levels were found across different ethnicities (p = 0.217) or BMI categories (p = 0.056). A significant increase in IMA levels was noted in ACS patients compared to control subjects (p < 0.001). Correlation analysis revealed significant associations between IMA levels and total cholesterol (r = 0.262, p = 0.009) and low-density lipoprotein (LDL) levels (r = 0.280, p = 0.006). Notably, a significant gender difference in IMA levels was found in obese patients, suggesting physiological differences in response to obesity. The study also revealed higher IMA concentrations in NSTEMI and STEMI patients compared to those with unstable angina. CONCLUSION: The study confirms elevated IMA levels in ACS patients, supporting its diagnostic potential. It reveals demographic influences, such as higher IMA levels in younger males and significant gender-specific differences in obese patients. Personalized approaches considering demographics and lipid management are essential for ACS risk reduction and IMA's role in management.

BACKGROUND: Cardiovascular Diseases (CVD) account for the highest number of deaths and disability globally and within Sri Lanka. A CVD risk prediction tool is a simple means of early identification of high-risk groups which is a cost-effective preventive strategy, especially for resource-poor countries. Distribution of risk factor levels varies in different regions even within the same country, thus a common risk estimation tool for the country may give false local predictions. Since there are few published data related to Sri Lanka the aim of this study was to recalibrate the Framingham equation according to the local risk factor profile of a population in the Kurunegala region in Sri Lanka. METHOD: A cross-sectional study was conducted with the participation of 1 102 persons from the Kurunegala Regional Director of Health Services area and the data was collected using an interviewer-administered questionnaire, anthropometric, blood pressure, and biochemical measurements. CVD risk was estimated using Framingham original and recalibrated CVD risk assessment methods. Current CVD mortality and morbidity data and the recalibration method conducted by the method described by Wilson and colleagues were used for calculations. RESULTS: Original and recalibrated Framingham CVD risk scores predicted 55.5% (N = 612) and 62.3% (N = 687) to be having less than 10% CVD risk respectively. Further, the original and recalibrated CVD Risk Scores predicted 2.2% (N = 24) and 1.8% (N = 20) to be having CVD risk more than 40% respectively. CONCLUSION: These findings show an over prediction of the CVD risk with the original Framingham risk calculations which signifies the importance of development of a region-specific risk prediction tool using local risk factor data in Sri Lanka which will prevent unnecessary expenditure to manage people without risk of CVD.

BACKGROUND: Hypertension (HT) is identified as a highly prevalent cardiovascular risk factor and also as a separate disease entity, leading to significant mortality and morbidity. The rate of HT is increasing worldwide with a faster rate identified in developing countries. Thus, it is important to evaluate epidemiological patterns of chronic HT in a developing country like Sri Lanka. METHODOLOGY: This is a cross-sectional descriptive study conducted at the Teaching Hospital Peradeniya, Sri Lanka, to assess symptoms and risk factors among patients with chronic HT. RESULTS: In a cohort of 266 chronic hypertensives, the mean values for age of population, age of onset, and duration of HT, respectively, are 63, 45, and 8 years. At presentation, 24.8% were asymptomatic. The commonest presentation at diagnosis was dizziness accounting for 33.8% cases, followed by chest pain, headache, loss of consciousness, and shortness of breath accounting for 7.5%, 13.5%, 2.6%, and 4.5%, respectively. Approximately 36.5% of patients had a positive family history. Fathers of 7.1% patients, mothers of 19.2%, and both parents of 10.2% patients had HT. 38.7% of patients had one or more siblings with HT. 34.6% had diabetes mellitus. CONCLUSION: Symptoms of those with HT are mostly nonspecific and should be considered as possible warning signs prior to the development of sinister complications of the disease. Family history of HT with affected siblings, or one of the parents, was, observed in more than one-third of patients. Early screening and prevention of modifiable risk factors are important in these patients to prevent debilitating complications.

OBJECTIVE: Levamisole (LEV) has been used successfully on an alternate-day regime of 2.5 mg/kg in steroid-dependant nephrotic syndrome (SDNS) to maintain remission. This pilot study was carried out between 2010 and 2015 at a single center in Sri Lanka to evaluate the efficacy of LEV prescribed at 2.5 mg/kg daily, which is double the alternate-day dose. METHODS: Sequential children with SDNS, relapsing more than twice in the preceding 12 months and previously treated with LEV and low-dose alternate-day prednisolone (0.1-0.6 mg/kg) were recruited to the study. This group received LEV (2.5 mg/kg) daily with the same dose of alternate-day prednisolone for 1 year. Urine protein excretion was recorded by parents on a daily basis, and the presence of 3+ proteinuria on 3 consecutive days was considered a relapse. Full blood counts and liver function tests were performed every 3 months to monitor for adverse effects. RESULTS: Sixty-four children were enrolled into the study; six were excluded due to prescription of other immunosuppressive drugs. Median age was 7.9 years; 33 were boys. The number of relapse episodes was 163 [mean per patient 2.8 ± standard deviation (SD) 0.8] in patients on alternate-day LEV and 77 (mean 1.3 ± SD 0.9) for those on daily LEV during the 12-month period of observation. The P value 0.000 (according to the Wilcoxon signed-rank test) was <0.001. No major adverse events were noted. CONCLUSIONS: The prescription of daily LEV is effective and safe for maintaining SDNS remission.

The mortality and morbidity of road traffic accidents (RTA) is increasing in the South Asian region, including Sri Lanka. Therefore, the demographic factors, types of vehicles involved, and the severity of injuries sustained in RTA was studied. Age, gender, and details of the incident of all patients admitted to hospital following a RTA, between January 2007 and August 2012, were obtained by interview. Following a medico-legal examination, the type and severity of injuries was categorized as, non-grievous, grievous, endangering life or fatal in the ordinary course of nature. Of the 579 RTA casualties examined, 72% were males, 28% females, and 26% were in the 20-29 year age group. There were 44% passengers, 32% drivers, and 20% pedestrians. Of the 440 vehicle occupants, 37% were on motor cycles, 28% in three wheelers, 13% in dual purpose vehicles and 11% in buses. Of the 114 pedestrians, 33% had been struck by motor cycles, 19% by three-wheelers and 17% by dual purpose vehicles. There was at least one soft tissue injury in 84%, whilst 45% had one or more fractures. In 85% of bicycle riders, the injuries were grievous, endangering life or fatal in the ordinary course of nature. A high proportion of young adults sustained grievous injuries due to RTA. Almost two thirds of the casualties resulted from motorcycle or three wheeler accidents. Laws limiting the number of passengers carried, installation of side doors, mandatory use of seat belts in three wheelers, and protective garments for motorcyclists are recommended.

Currently, interventions for HIV/AIDS control in Sri Lanka are only carried out among the most-at-risk populations. This study was conducted to identify the level of awareness and stigma-related attitudes among the general population of Sri Lanka. A cross-sectional study was carried out among 869 residents of 18-64 years of age in Kandy, Sri Lanka. A self-administered questionnaire was utilised to obtain information about stigma, discrimination and HIV/AIDS-related knowledge. Chi-square test and multivariate analysis were applied to find possible associations between HIV-related variables and socio-demographic indicators. Response rate was 82.0%. Overall, 93.5% of the participants have heard of HIV/AIDS but the knowledge on HIV/AIDS was low with an average score of 51.7%, no statistically significant difference between genders (p = 0.352). Only 58.1% were aware that a condom was an effective tool for its prevention. There were many misconceptions related to epidemiology of HIV/AIDS. The participants showed more positive attitudes towards HIV/AIDS and people living with HIV/AIDS (PLHIV) for all questionnaire items except for those listed under shame and blame. Positive attitudes towards PLHIV were observed to be greater among those with a better HIV/AIDS-related knowledge score. There was no significant association between the attitudes towards PLHIV and socio-demographic characteristics such as ethnicity and religion. There is a greater need of making attempts towards educating the public regarding HIV/AIDS to eliminate misconceptions prevalent in the society. Stigma-related attitudes are mainly due to shame and blame associated with the disease. As the attitudes towards PLHIV were more positive among those with a better HIV/AIDS-related knowledge score, targeted HIV/AIDS-related health education interventions maybe recommended in this regard.

Background: Evidence-based practice (EBP) is an effective approach to improve maternal and newborn outcomes at birth. Objective: This study aimed to assess the current intrapartum practices of a tertiary care hospital in Central Province, Sri Lanka, during vaginal births. The benchmark for this assessment was the World Health Organisation's (WHO) recommendations on intrapartum care for a positive childbirth experience. Methods: An observational study was conducted at the delivery room of Teaching Hospital, Peradeniya with the participation of 196 labouring women who were selected using systematic random sampling. A non-participant observation checklist covering labour room admission procedures, management of the first, second, and third stages of labour, and immediate care of the newborn and postpartum mother was used for the data collection. The care interventions implemented throughout labour and childbirth were observed and recorded. The data analysis was done using SPSS version 22. Results: WHO-recommended practices such as providing privacy (33.2%), offering oral fluids (39.3%), and opioids for pain relief (48.5%) were found to be infrequent. Encouraging correct pushing techniques (77.6%), early breastfeeding (83.2%), regular assessment of vaginal bleeding (91.3%), skin-to-skin contact (93.4%), and using prophylactic uterotonics (100.0%) were found to be frequent. However, labour companionship, use of upright positions during labour, women's choice of birth position, and use of manual or relaxation techniques for pain relief were not observed in hospital intrapartum care. Conclusion: The findings of the study indicate that additional attention and monitoring are required to align the current intrapartum care practices with the WHO recommendations. Moreover, the adoption of evidence-based intrapartum care should be encouraged by conveying the standard evidence-based intrapartum care guidelines to the grassroots level healthcare workers to avoid intrapartum interventions.
RESUMO
BACKGROUND: South Asians living in western countries are known to have unfavourable cardiovascular risk profiles. Studies indicate migrants are worse off when compared to those living in country of origin. The purpose of this study was to compare selected cardiovascular risk factors between migrant Sri Lankans living in Oslo, Norway and Urban dwellers from Kandy, Sri Lanka. METHODS: Data on non fasting serum lipids, blood pressure, anthropometrics and socio demographics of Sri Lankan Tamils from two almost similar population based cross sectional studies in Oslo, Norway between 2000 and 2002 (1145 participants) and Kandy, Sri Lanka in 2005 (233 participants) were compared. Combined data were analyzed using linear regression analyses. RESULTS: Men and women in Oslo had higher HDL cholesterol. Men and women from Kandy had higher Total/HDL cholesterol ratios. Mean waist circumference and body mass index was higher in Oslo. Smoking among men was low (19.2% Oslo, 13.1% Kandy, P = 0.16). None of the women smoked. Mean systolic and diastolic blood pressure was significantly higher in Kandy than in Oslo. CONCLUSIONS: Our comparison showed unexpected differences in risk factors between Sri Lankan migrants living in Oslo and those living in Kandy Sri Lanka. Sri Lankans in Oslo had favorable lipid profiles and blood pressure levels despite being more obese.

OBJECTIVE: Hypertension (HTN) remains a major risk factor for cardiovascular diseases globally. Despite considerable improvement in increasing awareness, treatment, and control of HTN, undiagnosed and uncontrolled HTN remains a major public health challenge. Our focus was on studying the knowledge, attitude, and practice regarding HTN in adult hypertensive patients at a tertiary care hospital in Sri Lanka. Methodology. A descriptive study on knowledge, attitude, and practice of hypertensive patients on antihypertensive medications attending the hypertensive clinic was carried out from January 2016 to June 2016 at THP. RESULTS: The study was on a total of 371 hypertensive patients comprising 253 (68.2%) females and 118 (31.8%) males. Among the total participants, 12 (3.2%), all females, had never been to school. About half of them (47.7%) had not even reached GCE (ordinary level). More than two-thirds (77%) of the study population were aware of the complications of HTN as they were informed by a health care team member. About 74% of them were taking all their prescribed medications. Almost all (95%) patients had checked their blood pressure (BP) during the previous 12 months, and almost the same percentage had visited their doctor for BP checkups every 1-3 months. CONCLUSION: Our patients were well aware of the importance of regular follow-ups and also knowledgeable about the complications related to HTN. Almost 75% of the patients had optimum drug compliance. It was revealed that forgetfulness was the frequent cause for poor drug compliance.
RESUMO
Objective. This study aims to describe the clinical features in terms of pain perception, ankle range of motion, and foot volume in participants with recurrent ankle sprains compared with first-time sprains. Methods. Individuals with grade I and II ankle sprains were referred to physiotherapy care for further rehabilitation by their general practitioner. Primary outcome measures were range of movement, pain, and foot volume. Recurrences were described according to engagement in sport. Results. A total of 115 participants were recruited (age = 22.2 ± 6.9 years; female, 84). Neither pain level (P = .822), nor range of motion (dorsiflexion P = .452; plantar flexion P = .436; inversion P = .383; eversion P = .657), nor foot volume (P = .654) were significantly different between the groups: individuals with first-time sprain or with recurrences. Conclusion. Pain and high existence of other lower-limb injuries were reported disregarding the presence of a recurrence. Clinically, it is difficult to differentiate recurrent sprain from a first-time ankle sprain by means of foot volume, range of movement, or pain intensity.

BACKGROUND: Deliberate self-harm in the form of non-fatal self-poisoning is a major public health problem in Sri Lanka. Previous work suggests that many nurses in Sri Lanka-particularly those who work in primary care in the medical treatment of persons who attempt self-poisoning-already approach their role in a holistic fashion and consider "advising" or "counseling" patients after self-poisoning to be a part of their nursing role. But there is no formal training given to such nurses at present nor has the efficacy or feasibility of such an intervention been assessed in Sri Lanka. The aims of this pilot study are to explore the potential efficacy, acceptability, and feasibility of carrying out a counseling intervention that could be delivered by nurses for persons who present to hospital for medical management of non-fatal self-poisoning. METHODS/DESIGN: The study will be carried out at the Toxicology Unit of Teaching Hospital Peradeniya, Sri Lanka. A pilot randomized controlled trial will be carried out among participants admitted to Teaching Hospital Peradeniya for medical management of non-fatal self-poisoning. The primary objective of this study is to explore the acceptability and feasibility of a counseling intervention being delivered by nurses. The secondary objectives are to explore the efficacy of the intervention for the improvement of skills to cope with situations of acute emotional distress, and to reduce rates of anxiety, depression, and future repetition and suicidal ideation. A nurse's experiences and attitudes regarding the acceptability and feasibility of implementing this intervention and participant experiences of the intervention and its effects will be explored via qualitative interviews and focus group discussions. DISCUSSION: It is anticipated that the findings of this pilot study will help determine and assess the acceptability and feasibility of this counseling intervention, as well as indicate the more useful aspects of this intervention in order to develop it for further exploration in a larger trial. TRIAL REGISTRATION: SLCTR/2017/008 Registered on 21st March 2017.
RESUMO
OBJECTIVE: This retrospective study was conducted in 2017 with the objective of evaluating the value of acute phase peripheral blood parameters in predicting dengue haemorrhagic fever (DHF). Patients, who were admitted to Teaching Hospital Peradeniya between January and August 2017 due to dengue illness, were recruited into this study. RESULTS: A total of 515 patients participated in the study. Among them, 333 were DHF patients while 182 patients were managed as DF. There was a significant difference in mean values of platelets and haemoglobin observed during acute phase in non-leakers compared to the patients who progressed to DHF, while no significant difference was observed for white blood cells, neutrophils, lymphocytes and haematocrit values. A significantly higher mean value was observed in white blood cells and hemoglobin in leakers compared to non-leakers during day 5. Mean day 5 platelet value was significantly lower among leakers compared to non-leakers but no significant difference between haematocrit, neutrophil and lymphocyte values were observed. ROC curve performed for acute phase platelet values and haemoglobin values to gain a predictive value for female and male DHF patients and cut off values with high sensitivity and specificity to predict DHF could be obtained for the platelet count.

BACKGROUND AND AIM: There is increasing prevalence of inflammatory bowel disease (IBD) in Asia, but Sri Lankan data on the state of epidemiology and clinical course of IBD are scarce. METHODS: A hospital-based study was done by recruiting IBD patients who permanently reside in the Central Province (population 2.57 million, 12.6% of Sri Lankan population) of Sri Lanka. Cases were confirmed by standard criteria and data were collected from health records and patient interviews at clinic visits and hospital admissions. RESULTS: There were 200 cases of IBD; (ulcerative colitis [UC]-140, Crohn's disease [CD]-60, microscopic colitis-7). The crude prevalence rate of UC was 5.44/100 000 (95% CI 5.41-5.47/100 000) and CD was 2.33/100 000 (95% CI 2.31-2.35/100 000). Female to male ratios were 1:0.8 for UC but 1:1.5 for CD.Mean age at diagnosis was 42.0 and 31.9 years for UC and CD, respectively. One UC and one CD patient had positive family history of IBD. Among the UC patients, 60.7%, 24.3%, and 15% had proctitis, left sided, and extensive disease, respectively. At presentation, 62.1% of the UC patients have had moderately severe disease. 60% of the CD patients had only large bowel involvement and 80% had nonstricturing and nonpenetrating disease. Extra intestinal manifestations were present in 45.7% and 60.0% of UC and CD patients, respectively, in which peripheral arthralgia and arthritis being the commonest. 6.4% of UC and 23.3% of the CD patients (total of 23) required infliximab for induction of remission. CONCLUSION: The prevalence of IBD in the Central Province of Sri Lanka is lower than other Asian and Western populations. There is a predominance of male gender and isolated colonic disease in CD patients. UC patients have an equal gender distribution and a higher proportion of proctitis. CD needed induction with infliximab than UC.
RESUMO
Sri Lankans in Oslo have previously been shown to have lower risk of cardiovascular disease compared with those in Kandy, Sri Lanka. Here we present lifestyle risk factors for cardiovascular diseases: frequency and type of fat consumed, frequency of fruit and vegetable intake, alcohol consumption, and leisure time physical activity between 1145 Sri Lankans living in Oslo and 678 Tamils and Sinhalese Sri Lankans living in Kandy as possible explanatory factors for the differences observed. Those in Oslo were consuming healthier fats and reported higher levels of physical activity but frequency of vegetable and fruit consumption was lower. Alcohol consumption among women was negligible. Type of fats consumed might be protective for Oslo group compared with predominantly saturated fat diet in Kandy. Higher leisure time physical activity may also be protective for the Oslo group. Higher frequency of consumption of vegetables and fruits may be beneficial in Kandy.

Using data from 3 cross-sectional studies, the authors compared the estimated risk of cardiovascular diseases between migrant Sri Lankans in Oslo, Norway, and Tamils and Sinhalese in Kandy, Sri Lanka. The authors found that Sri Lankans in Oslo had significantly lower Framingham coronary heart disease (CHD) risk. Among men, the prevalence with estimated 10-year risk of a CHD event ≥10% was 20.6% in Oslo, 31.1% in Kandy Tamils, and 44.2% in Kandy Sinhalese. The corresponding figures in women were 10.4% in Oslo, 19.2% in Tamils, and 14.9% in Sinhalese. Risk of fatal cardiovascular disease estimated by the SCORE model showed a similar pattern. The Oslo group had a higher body mass index (BMI), but the differences were observed in all BMI categories. In conclusion, despite a lower BMI, Tamils and Sinhalese in Sri Lanka had higher estimated cardiovascular risk compared with Sri Lankans in Norway, mainly because of poorer lipid profiles.

Vitamin D deficiency is common in non-Western immigrant groups living in Western countries. A comparison of vitamin D status in individuals who have emigrated and individuals who remain in their country of origin is needed in order to provide information about the effect of moving to northern latitudes. A total of 196 participants aged 30-60 years in a cross-sectional population-based study in Kandy, Sri Lanka (latitude 7 degrees north) and 242 Sri Lankans aged 31-60 years participating in a cross-sectional population-based study in Oslo, Norway (latitude 60 degrees north) were included in the analysis. All serum samples were analysed for serum 25-hydroxyvitamin D (s-25(OH)D) in the same laboratory. Sri Lankans living in Norway had substantially lower s-25(OH)D (mean 31.5 nmol/l) compared with those living in Sri Lanka (mean 54.2 nmol/l), and the prevalence of s-25(OH)D < 25 nmol/l was 9.3 times higher (95 % CI 4.4, 19.6) in Norway compared with Sri Lanka. In Sri Lanka there was a clear seasonal variation with the lowest s-25(OH)D levels in August-September and the highest levels in November-December. We conclude that vitamin D status among Sri Lankans living in Kandy, Sri Lanka was considerably higher than that among Sri Lankans living in Oslo, Norway. The low vitamin D status commonly observed in non-Western immigrant groups living at northern latitudes should not be regarded as normal levels for these groups. However, also in Sri Lanka we found a profound seasonal variation with the lowest levels in August and September after the Monsoon.
