Knowledge, attitude, motivational factors and barriers for donating blood voluntarily among people aged between 18-55 years living in Manmunaipattu, Batticaloa
(University of Peradeniya, Sri Lanka, 2021-11-11) Kajenthini, K.; Madhuwanthi, L.D.M; Chandrika, J.P.M; Jayarathna, A.P.G.S.M
According to global data, there is a gradual decline in voluntary blood donations throughout the past decade. Increase in the life expectancy, rates of accidents and specialized surgeries have increased the rate of blood usage. It has become a global need to study on blood donation to obtain safe blood from the donors. The statistics available in the blood bank, Batticaloa number of voluntary blood donors are very less in all divisions. A cross sectional descriptive study was conducted by using an interviewed administered questionnaire, anonymous questionnaire to determine the knowledge, attitude, motivational factors and barriers among people in selected Grama Niladhari Divisions in Manmunaipattu. Simple random sampling method was used to select the sample. Validity of the study instrument was done by primary supervisor of our study, medical officer and nursing-in-charge attached to the blood bank. The ethical clearance was obtained from Ethical Review Committee, Faculty of Health care sciences, Eastern University. Data was entered, analyzed and interpreted using SPSS version 19. This study included 405 randomly selected participants with age range from 18-55 years with the mean age of 30(SD 7.8). Majority of them were females (52.1%), married (48.9%), Tamils Hindu (89.4%) and had secondary education (92.9%).33.1% of them had previous experience on voluntary blood donation. 51.36% had adequate knowledge on eligible criteria for blood donors.92.3% of them answered positively as blood donation is a healthy habit. Altruism, peer pressure was significant motivational factors, in which the majority accepted donating blood as social responsibility. 55% of them responded that fear of seeing blood, fear of needle pain and fear of gaining weight were major barriers for not to donate blood voluntarily. Motivating the individuals from the society for voluntary blood donation through conducting series of well-planned awareness programme is a novel finding of this study.
Effectiveness of yoga exercises to improve attention and concentration of athletes in Holy Angels Girls College, Kuliyapitiya, Sri Lanka
(University of Peradeniya, Sri Lanka, 2021-11-11) Piyumika, T.; Gunasekara, K.C.; Weerasinghe, S.
This study was conducted to explore the effect of yoga exercises to maintain attention and concentration of the school athletes during sports training. A sample of 60 athletes (netball/athletics/cricket) aged 13-15 years were selected using stratified random sampling and randomly assigned to control and treatment groups (n=30 per group). Participants of both the groups engaged in their respective sports training as usual. The treatment group underwent three yoga sessions per week for 03 months. All participants completed the Test of Attention and Concentration (TACL) before and after a training programme. TACL focuses on broad external attention (BET), broad internal attention (BIT), narrow effective focus (NAR), external overload attention (OET), internal overload attention (OIT), and errors of under-inclusion (RED). Paired t-test was used to compare between attention and concentration of athletes before and after training. According to results, pre- and post-test scores of the treatment group were significantly different (P<0.05) with respect to OIT (P=0.000), NAR (P=0.000), BIT (P=0.008) and RED (P=0.001) whereas no differences existed between scores for BET and OET. In contrast, pre- and post-scores of all tested traits did not differ (P>0.05) in control group. Thus, the proposed yoga session improved athletes‘ ability to concentrate on more than one task and effectively narrowed the attention/concentration focus, while reducing the difficulty of broadening attention focus and diminishing the tendency for internal overloading. In conclusion, the yoga training programme had a positive effect on concentration and attention of the sample.

(University of Peradeniya, Sri Lanka, 2021-11-11) Kodagoda, K.I.U.; Wickramarachchi, W.K.D.S.A.; Weerarathne, L.R.N.D.; Senarathne, U.D.
Albuminuria is a presence of abnormal amounts of albumin in urine that is considered as a sign of defective glomerular membrane. It can also be benign when present due to physical exercise; called ̳exercise induced albuminuria‘ which is reversible. Prime aim of this study was to identify the effect of cycling on urine albumin excretion. A quasi experimental research design was used for the study with an interventional approach. 12 –professional cyclists from Naval-base, Welisara were selected using total population sampling. Urine Albumin to Creatinine Ratio (ACR) was used to assess albuminuria before and after training sessions. Workout intensity was measured by calculations done using post training pulse rate. Hydration level was measured using the body weight loss, water intake and the urine volume passed. Paired t-test was used to analyze data from pre and post-test ACR levels. Pearson correlation test was used to identify the relationship between hydration level measured by sweating rate, and ACR increase, between intensity and ACR increase and between pre-test ACR level and post-test ACR level. There was a significant difference between pre session urine ACR and post session ACR (P=0.026). There was a positive correlation between the ACR difference and the intensity (p=0.002, r=0.793). There was no significant relationship between hydration level measured by sweating rate and the ACR difference (p=0.353, r=0.295)). There was a positive relationship between pre-session ACR and post-session ACR levels (p=0.000, r=0.987). The post exercise urine ACR was calculated to be 1.305 mg/mmol which was within the normal range according to the NICE Guidelines (2008) – UK though the amount had been increased. It was increased up to micro-albuminuria level. Testing urine albumin excretion 24-48 hours after training would be better to confirm recovery of athletes to ensure whether there is no negative effect of training on renal function.
Relationship between gym training and albuminuria among female gym trainees
(University of Peradeniya, Sri Lanka, 2021-11-11) Kodagoda, K.I.U.; Wickramarachchi, W.K.D.S.A.; Weerarathne, L.R.N.D.; Senarathne, U.D.
Albuminuria is presence of abnormal amounts of albumin in urine that is considered as a sign of defective glomerular membrane. It can also be benign when present due to physical exercise; 'called exercise induced albuminuria‘ which is reversible. Prime aim of this study was to identify the effect of gym training on urine-albumin excretion. A quasi-experimental research design was used for the study with an interventional approach. 30 female gym trainees in Gampaha divisional secretariat division were selected using proportionate stratified random sampling. Urine Albumin to Creatinine Ratio (ACR) was used to assess albuminuria before and after training sessions. Workout intensity was measured by calculations done using post-training pulse rate. Hydration level was measured using body weight loss, water intake and urine volume passed. Pearson correlation was used to identify the relationship between hydration level measured by sweating rate, and ACR increase, between intensity and ACR increase and between pre-session ACR level and post-session ACR level. There was a significant difference between pre-session urine ACR and post-session ACR (P=0.002). There was a positive correlation between ACR difference and intensity (p=0.003, r=0.521). There was no significant relationship between sweating rate and ACR difference (p=0.379, r=- 0.182)). There was a positive relationship between pre-session ACR and post-session ACR levels (p=0.010, r=0.473). According to the statistical analysis, the mean value of pre-exercise albumin level of the gym trainees was 1.147 mg/mmol indicating that their average urinary albumin excretion is within the accepted normal range. The post- exercise urine ACR was found as 3.293 mg/mmol indicating that urinary albumin excretion has increased to the range of micro-albuminuria following exercise according to the NICE Guidelines (2008) – UK. Testing urine albumin excretion 24-48 hours after training would be better to confirm recovery of athletes to ensure whether there is no negative effect of training on renal function.
Importance of radiographic measurements in diagnosis of megaesophagus in dogs and their association with hypothyroidism
(University of Peradeniya, Sri Lanka, 2021-11-11) Dharmaratne, G.K.; Gunathilaka, G.A.D.K.K.; Ranasinghe, R.A.V.S. J.; Abeykoon, C.; De Silva, D.D.N.
Megaoesophagus is a disorder of the oesophagus in human and other mammals, in which the oesophagus is enlarged abnormally. Lack of normal peristaltic movements, paralysis of oesophageal musculature or obstructions are the causes of this condition. Megaoesophagus could arise secondary to underline conditions such as hypothyroidism, immune mediated diseases, and congenital conditions etc. Plain thoracic radiography is useful in the diagnosis of megaoesophagus in dogs as the delineation of the oesophageal wall is well visualized. The objective of the current study is to find the association between the Relative Oesophageal Diameters (ROD) with proven cases of hypothyroidism. ROD is the ratio between Thoracic Inlet Diameter and average oesophageal diameter (OD). Medical records of twenty dogs with megaoesophagus admitted to the Veterinary Teaching Hospital, University of Peradeniya from 2020 to 2021 February, were reviewed. The OD was measured in each left lateral radiograph using the image processing software (FCR PRIMA V Console). The measurements were taken in parallel with a line drawn perpendicular to the midpoint of the body of each thoracic vertebra (T1-T10). Also, four radiographic findings, the triangular air column in cervical oesophagus, trachea-oesophageal stripe sign, diffuse oesophageal dilatation and aspiration pneumonia were assessed. In comparison, 6 cases of proven hypothyroidism (T4 levels < 1.0 μg/dL) showed severe oesophageal dilatation as evident in the radiographs. Two sample t test (α = 5%), showed there is a significant difference between the mean ROD values of hypothyroidism cases and non-hypothyroidism cases (P=0.0452). In addition, the radiographic findings, the triangular air column in cervical oesophagus and trachea-oesophageal stripe sign were also prominent. It is concluded that ROD could be used to confirm that megaoesophagus is caused by hypothyroidism.
