Fulltext Chronic lymphocytic leukaemia: a review of 7 cases from University Hospital, Kuala Lumpur

Chin NS, Bosco J, Teh A

Med J Malaysia, 1990 Mar;45(1):23-8.
PMID: 2152065

Chronic lymphocytic leukaemia (CLL) is rare locally. Seven CLL patients which constituted 0.9% of the total 747 cases of leukaemic patients were diagnosed over a 5 year period. They had similar haematological profiles as Western patients though most of them had advanced disease at presentation. Treatment of CLL patients was palliative and should be reserved for symptomatic patients and/or patients with progressive disease.
Fulltext A study of 31 patients with easy bruising from University Hospital, Kuala Lumpur

Chin NS, Koong PL

Med J Malaysia, 1990 Dec;45(4):325-8.
PMID: 2152054

Thirty one patients were investigated for the main complaint of easy bruising. These patients had normal platelet count with no past history of immune thrombocytopenia or systemic disorders known to predispose to bruising and a negative drug history. The evaluation of these patients included clinical review (history and physical examination) plus coagulation tests consisting of bleeding time, prothrombin time, partial thromboplastin time, thrombin time, fibrinogen level, FXIII screen and platelet functions test. Seven of the paediatric patients had acquired platelet dysfunction with eosinophilia (APDE). In 17 (94.4%) of the 18 adult patients no abnormality was demonstrated. Hence APDE was the commonest cause of easy bruising in children while the haemostatic defect contributing to easy bruising in adults remained unknown.

Chin NS, Khoo S, Low WY

J Hum Kinet, 2012 Jun;33:151-61.
PMID: 23486244 DOI: 10.2478/v10078-012-0054-0

This study investigated gender, age group and locality differences in adolescent athletes' self-determination motivation and goal orientations in track and field. It also examined the relationship between the self-determination theory and achievement goal theory. A total of 632 (349 boys, 283 girls) adolescent athletes (aged 13-18 years) completed the Sports Motivation Scale and Task and Ego Orientation in Sport Questionnaire. Results indicated significant differences between gender on intrinsic motivation, extrinsic motivation, amotivation (t(630) = 4.10, p < 0.05) and ego orientation (t(630) = 2.48, p < 0.05). Male students reported higher intrinsic motivation, extrinsic motivation, amotivation and ego orientation. A significant difference was found between age groups on task orientation (t(630) = 1.94, p < 0.05) and locality on ego orientation (t(630) = 1.94, p < 0.05). Older athletes showed significantly higher task orientation. Rural athletes had higher ego orientation whereas urban athletes have higher intrinsic motivation. Task orientation was related to intrinsic motivation (r = 0.55, p < 0.01), extrinsic motivation (r = 0.55, p < 0.01), but weakly related to amotivation (r = 0.10, p < 0.01). Ego orientation was related to intrinsic motivation (r = 0.30, p < 0.01), extrinsic motivation (r = 0.36, p < 0.01) and amotivaion (r = 0.36, p < 0.01). Task orientation was related to ego orientation (r = 0.29, p < 0.01). Multiple regression analysis showed intrinsic motivation, extrinsic motivation and amotivation accounted for 30.5% of the variances in task orientation.

Ling A, Teo EW, Chin NS

Malays J Med Sci, 2019 Jul;26(4):86-93.
PMID: 31496897 MyJurnal DOI: 10.21315/mjms2019.26.4.10

Background: The Sport Commitment Model is widely used to understand the motivation and commitment of athletes to continue playing sports. However, the factors influencing athletes' commitment to racquet sports have not received much research attention, especially in Malaysia.
Purpose: This study aims to use the Sport Commitment Questionnaire-2 (SCQ-2) to examine Malaysian athletes' commitment to racquet sports.
Methods: A total of 612 athletes (367 males/245 females, μ age= 30.32 ± 11.56) completed the SCQ-2, which measures seven factors and two dimensions of sport commitment.
Results: The results revealed that sport enjoyment was the main factor contributing to the athletes' commitment in all sports. Two-way ANOVA analyses showed significant differences in athletes' enthusiastic commitment [F(3,604) = 44.92, P = 0.00] and constrained commitment [F(3,604) = 15.32, P = 0.00] across four sports. There were also significant differences in both enthusiastic commitment [F(3,604) = 7.53, P = 0.00] and constraint commitment [F(3,604) = 18.82, P = 0.00] across age groups.
Conclusion: Enjoyment is the main factor in sport commitment. Tennis athletes possess the highest level of enthusiastic commitment across all the racquet sports. Moreover, male athletes showed higher levels of enthusiastic commitment than female athletes.

Rajiah K, Maharajan MK, Chin NS, Num KS

Virusdisease, 2015 Dec;26(4):297-303.
PMID: 26645041 DOI: 10.1007/s13337-015-0287-3

The major cause of cervical cancer is human papillomavirus (HPV) for which vaccination is available. The success HPV vaccination programme largely depend on the degree of knowledge of the healthcare providers who can recommend to the public. Health sciences students as future healthcare providers play a major role in HPV vaccination initiatives. The objective of this study was to evaluate the knowledge, attitude, practice and to find out the willingness to pay for HPV vaccination among the health sciences students in a private university. The cross-sectional study was conducted among the university students studying health sciences program using a validated questionnaire to measure their awareness and acceptance of HPV vaccination. The students demonstrated moderate knowledge about HPV infection and vaccination with mean knowledge scores of 9.3 out of 17. Students were showing positive attitude towards HPV vaccination with mean scores of 3.80 out of 5. However, low HPV vaccination uptake rate was reported among the students. Most of the students were willing to recommend HPV vaccine. The participants felt that the cost is the major barrier towards HPV vaccination and they felt the government should cover the cost of vaccination for all. The results of this study may be helpful in establishing educational policies on cervical cancer-related topics in the universities.

PMID: 35035364 DOI: 10.3389/fpsyg.2021.691324

The purposes are to deepen the understanding of the correlation between learning motivation and learning burnout and thereby stimulate the learning motivation of college students. According to the theory of educational psychology, mechanism of learning motivation, and causes of learning burnout are analyzed. The learning motivation and learning burnout of college students majoring in sports are taken as the breakthrough point. The learning motivation and learning burnout situation of Chinese and Malaysian students majoring in sports are surveyed and compared through questionnaires. In addition, Chinese students majoring in sports are taken as examples to analyze the impact of learning motivation on learning burnout. The correlations between various dimensions are analyzed to determine the impact of learning motivation on learning burnout. The total learning motivation scores of students from the Sport School of Zhengzhou University and the University of Malaya Centre for Sport and Exercise Sciences are 122.3 ± 22.4 and 140.2 ± 23.6, respectively, and their average scores for each question are 3.60 and 4.07, respectively. The total learning burnout scores of students from the Sport School of Zhengzhou University and the University of Malaya Centre for Sport and Exercise Sciences are 58.2 ± 8.95 and 53.6 ± 7.34, respectively. The learning motivation of Malaysian college students majoring in sports is slightly stronger than Chinese students. Compared with Malaysia, the learning burnout of college students majoring in sports in China is extra apparent, mainly exhibited in the two dimensions of depression and a low sense of achievement. The learning motivation and learning burnout of college students majoring in sports are negatively correlated; that is, the stronger the learning motivation, the weaker the learning burnout; on the contrary, the weaker the learning motivation, the more severe the learning burnout. In conclusion, learning burnout of college students can be reduced by correcting and stimulating their learning motivation and improving their learning self-efficacy.

Int J Environ Res Public Health, 2021 11 07;18(21).
PMID: 34770207 DOI: 10.3390/ijerph182111694

The 18-item Sport Motivation Scale (SMS-II) is one of the most-utilised scales measuring athletes' motivation and its psychometric properties. However, we found no Malay version used to examine the Malaysian multi-ethnic population. Thus, the study aimed to translate and validate the SMS-II into the Malay version using confirmatory factor analysis. A total of 436 (16.44 ± 1.22) state athletes were asked to complete the SMS-II Malay version, which utilised the forward-backwards translation method. The results showed an acceptable fit with the data (CFI = 0.906, SRMR = 0.064; RMSEA = 0.056) and internal consistency, with a Cronbach's alpha value that exceeded 0.50, which supported its usage for the assessment of motivation among the multi-ethnic Malaysian athletes. The Cronbach's alpha values of all the factors were satisfactory, except for introjected regulation. Thus, further studies are needed to improve the reliability of such factors. Nonetheless, the Malay version of SMS-II was found to be valid and reliable for assessing the level of motivation of the multi-ethnic Malaysian athletes.
Chronic adult primary immune thrombocytopenia (ITP) in the Asia-Pacific region

Heng LL, Caguioa P, Chin NS, Chiou TJ, Lee JW, Miyakawa Y, et al.

Int J Hematol, 2011 Aug;94(2):142-149.
PMID: 21766185 DOI: 10.1007/s12185-011-0894-8

Patients with primary immune thrombocytopenia (ITP) from the Asia-Pacific region often exhibit characteristics distinct from those of patients from the West. Moreover, as the region itself is heterogeneous, the ITP landscape among individual Asia-Pacific countries can be diverse. The recently released international consensus report on ITP places new emphasis on ITP, but does not address the unique ITP landscape in the Asia-Pacific region, which is home to 60% of the world's population. In an attempt to characterize how the ITP landscape differs between the West and the Asia-Pacific region, an expert panel with representatives from Northeast Asia, Southeast Asia, and Australia was convened. Important differences were identified between the guidance provided in the international consensus report and experience in the Asia-Pacific region, namely diagnostic practices, incidence and approach to ITP secondary to H. pylori infection, systemic lupus erythematosus-related ITP, the use of bone marrow examination, initial treatment strategies, and the role of splenectomy, rituximab, and thrombopoietin receptor agonists.

Exploring Physical Education Teachers' Intention and Perceived Constraints in Offering Online Lessons Using the Theory of Planned Behavior: A Multi-Country Analysis

Konukman F, Filiz B, Moghimehfar F, Maghanoy MA, Graber K, Richards KA, et al.

Behav Sci (Basel), 2024 Apr 09;14(4).
PMID: 38667101 DOI: 10.3390/bs14040305

Guided by the theory of planned behavior, this study aimed to determine the influence of Physical Education (PE) teachers' attitudes, their perceived behavioral control, and the influence of subjective norms on their intention and constraints (intrapersonal, interpersonal, and structural) to offer a high-quality class based on best practices to deliver PE lessons online during the COVID-19 pandemic. This cross-sectional, multi-country survey study recruited PE teachers from five countries (China, Malaysia, the Philippines, Turkey, and the United States). A total of 928 online questionnaires were used in the analysis. In terms of the overall intention to teach online, our findings showed that American and Filipino teachers had higher levels of intention to continue teaching online. In contrast, Turkish, Malaysian, and Chinese teachers showed a lower interest. Moreover, Malaysian teachers had more intrapersonal constraints while the teachers in the other four countries were not as restrained intrapersonally. The results highlight the significant influence of perceived behavioral control and attitudes on PE teachers' intention to deliver online courses. Constraints to online teaching had a considerably large negative impact on attitudes, subjective norms, and perceived behavioral control. Based on the results, the proposed extension to the theory of planned behavior was an appropriate framework for understanding the behavioral intent of PE teachers.
