Study purposeThe aim of this study was to determine the fractional exhaled nitric oxide (FeNO) levels, exhaled breath carbon monoxide (eCO) levels, blood pressure, blood lipid levels between smokers and non-smokers and to determine the association of smoking intensity with the above parameters.MethodsThis descriptive study was conducted in selected periurban areas of the Colombo District, Sri Lanka. Adult male current tobacco smokers (n=360), aged between 21 and 60 years were studied and compared with anthropometrically matched male non-smokers (n=180). Data were collected by interviewer-administered questionnaire, clinical assessment and measurement of FeNO by FENO monitor and eCO bySmokerlyser.ResultsSmokers had significantly lower mean FeNO levels and higher mean eCO values compared with non-smokers. Presentation of palpitations was higher among the smokers and a significantly positive correlation was identified between palpitations and eCO levels. There was a significantly positive correlation between the systolic blood pressure of smokers with the duration of smoking (DS), Brinkman Index (BI), Body Mass Index (BMI) and there was a significantly negative correlation with FeNO levels. The mean arterial pressure was positively correlated with the DS, BI and BMI. There was a significantly negative correlation between FeNO and the number of cigarettes smoked per day, DS and BI of smokers. Significantly higher total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), very LDL-C, TC: HDL ratio and low high density lipoprotein cholesterol (HDL-C) level was observed among smokers compared with the non-smokers.ConclusionsTobacco smoking was found to impact blood pressure and serum lipid levels thus enhancing the cardiovascular risk among smokers. The levels of eCO and FeNO are useful biomarkers for determining the intensity of smoking. The results indicate the necessity for urgent measures to stop cigarette smoking in Sri Lanka.

The prevalence of Type 2 Diabetes Mellitus (T2DM) and its complications continue to rise across the globe including Sri Lanka. Diabetes Self-care activities (DSCA) are promising behaviors to reduce complications and to achieve good glycaemic control. There is a lack of data regarding DSCA and its association with glycaemic control among adults with T2DM in Sri Lanka. A descriptive cross-sectional study was conducted among purposively selected adults with T2DM (n = 300) in a teaching hospital, Sri Lanka to determine the association between DSCA and glycaemic control. Apre-tested interviewer-administered questionnaire which includes socio-demographic, diabetes-related information and Summary of Diabetes Self-care activities questionnaire was used to collect data. Data were analyzed by using descriptive statistics and Chi-square test. General diet (Healthy eating plan) (OR = 3.04, 95% CI = 1.04-8.88, p = 0.034), Physical activities (OR = 2.26, 95% CI = 1.29-3.97, p = 0.004), Medication adherence (OR = 2.87, 95% CI = 1.24-6.64, p = 0.011) were significantly associated with HbA1c. Medication adherence was significantly associated with poor fasting blood sugar (FBS) (OR = 1.90, 95% CI = 1.07-3.37, p = 0.028). The findings highlight the need for health professionals to implement health education programs on diabetes self-care activities for adults with T2DM to enhance their adherence to DSCA, as well as to maintain glycemic control.

Introduction Pain is one of the most common and unpleasant symptoms that distress the well-being of patients with cancer. Considerable evidence supports the validity and reliability of the McGill Pain Questionnaire (MPQ) and its short forms, the SF MPQ and SF MPQ-2—which are the most widely used tools for pain assessment—in terms of patients with cancer. Pain and its characteristics are best assessed using validated and culturally adapted tools developed in participants' mother tongue. Although many pain assessment tools are available worldwide, only a limited number of them have been translated into Sinhala language and validated in Sri Lanka. We aimed to translate SF MPQ-2 into Sinhala language and validate using Sinhala-speaking patients suffering from cancer pains in Sri Lanka. Materials and Methods Translation has been conducted according to the guidelines laid down by Mapi Research Trust, in five stages, namely, forward translation, backward translation, expert opinion, cognitive debriefing interviews, and proofreading. The questionnaire was administered among 207 patients attending Apeksha Hospital, Sri Lanka, who are suffering from cancer pain. Content validity was tested using expert opinion, and face validity, by interviewing patients with cancer pain. Factor structure was tested through a factor analysis, and reliability, by internal consistency with Cronbach's alpha. Results A total of 207 participants (112 males and 95 females), aged between 20 and 80 years, were included in the study. Factor analysis identified four factors compatible with studies done in other countries, which explained 53.5% of the variance. The analysis of data indicated Cronbach's alpha of neuropathic, affective, intermittent, and continuous subscales as 0.768, 0.791, 0.824, and 0.789, respectively, which were over the acceptable threshold of 0.70. Confirmatory factor analysis supported the four-factor model. Conclusion SF MPQ-2-Sinhala version is a statistically proven reliable and valid pain descriptor which can be utilized to evaluate pain suffered by patients with cancer in Sri Lanka whose mother tongue is Sinhala.

Background The learning environment is a vital part of the undergraduate curriculum which enable to delivery of quality education in the stipulated time. Therefore, this study aimed to evaluate the learning environment among BSc. Nursing undergraduates in Sri Lankan state universities. Methods A descriptive cross-sectional study was conducted among 161 final year BSc. Nursing undergraduates in six state universities. Socio-demographic characteristics were collected using a self-administered questionnaire. The Dundee Ready Educational Environment Measure (DREEM) questionnaire was used to evaluate the learning environment in Perception of learning (SPL), Perceptions of teaching (SPT), Academic self-perceptions (SASP), Perceptions of the atmosphere (SPA), and Social self-perceptions (SSP). Based on the SPL, SPT, SASP, SPA, and SSP domains, the overall score of learning environment was ranged from 0 to 200 and then the overall score was classified into four categories such as poor (0–50), many problems (51–100), more positive than negative (101–150) and excellent (151–200). One-way Analysis of Variance (ANOVA) and t-test were used to determine the difference in the subscales and the overall scale. Results The mean age of the students was 24.9 ± 0.9 years. The overall score of the learning environment was 127.1 ± 14.3. Student’s Perception of learning showed the highest mean score of 31.1 ± 3.9 while the social self-perception showed the lowest score (mean 16.4 ± 3.1). A significant group effect was observed in SPL and SPT subdomains among state universities while no significant group effect was observed in other subdomains. Furthermore, participating in extracurricular activities, travelling time to the faculty, and gender were observed as associated factors for the learning environment among BSc. Nursing undergraduates in state universities. Conclusions Although the overall learning environment of BSc. Nursing undergraduates in state universities in Sri Lanka was within more positive than negative category, none of the university reaches to the excellent category. Therefore, each university should have improved their subdomains of learning environment to reach excellent category through addressing the gaps of curricular and extracurricular activities in the future.
