    Patient education has been considered as an  integral component of care for patient after myocardial infarction. Post myocardial infarction patients require information and knowledge related to their conditions to reduce anxiety and aid recovery. The objective of this study was to identify nurses’ perception on information needs of post MI patients of UKMMC. A cross sectional study using Cardiac Patient Learning Needs Inventory (CPLNI) adopted from Timmins and Kalizer (2002) was used. It comprises seven cate-gories: related to anatomy and physiology, psychological factor, life style factor, medi-cation information, dietary information,  physical activity, and symptom management. This study was conducted in coronary care unit (CCU), coronary rehabilitation ward (CRW), medical ward 1 and medical ward 2 from January 2007 to March 2007. 56 res-pondents (96%) who fulfilled the inclusion criteria were recruited in this study. Results showed that CCU and CRW respondents ranked symptom management as their first ranking followed by medication, life style factor, anatomy and physiology, dietary in-formation, physical activity and psychological factor. However, respondents in Medical Ward 1 and 2 reported and ranked medication information as their top priorities fol-lowed by symptom management, psychological factors, dietary information, physical activity, anatomy and physiology and life style factor. There were significant differ-ences between ward nurses’ responses with their perception related to anatomy and physiology, psychology factor, life style factor, physical activity, and symptom man-agement with p value

    Introduction: In Malaysia, private office workers tend to be more physically inactive due to work burden. This study aimed to determine physical activity level, motivation factors and barrier towards physical activity among private office workers. Methods: A cross sectional study using convenience sampling was conducted at nine private com- panies in Selangor involving 106 office workers aged 21 to 55 years old. Self-administered questionnaires includ- ing Global Physical Activity Questionnaire (GPAQ), Physical Activity and Leisure Motivation Scale (PALMS) and Physical Activity Barrier (PAB) were administered. Results: Over half of the respondents (58.5%) were having low physical activity level. The main motivation factors include physical condition, psychological condition and mastery. Meanwhile, tired after work, laziness, lack of discipline, family commitment and adverse weather were the main perceived barriers. A weak positive correlation was found between total motivation score and total physical activity (r=0.296; p=0.002). In contrast, there was a weak negative correlation between barriers and total physical activity (r=-0.237; p=0.015). Conclusion: The current physical activity level, its main motivation factors and barriers among private office workers were identified, providing an opportunity to create effective setting-based health promotion and intervention. It is also recommended that policy suggestions are made to influence and prepare essential partners (e.g. companies and employees) to promote ways of incorporating physical activity into one’s daily routine.

    The aim of this study was to compare physical activity prevalence estimates among the International Physical Activity Questionnaire (IPAQ), steps/day, and accelerometer in a sample of government employees in Kangar, Perlis, Malaysia. Ten government agencies in Kangar were randomly chosen, and all employees were invited to participate. A self-administered questionnaire was employed to obtain information on socio-demographic characteristics and a physical activity assessment using the IPAQ. Anthropometric measurements, which include measurements of weight, height, body mass index, percent body fat, waist and hip circumference, were carried out. An accelerometer was used to assess total daily energy expenditure and the number of steps/day. A total of 272 respondents were involved in this study with a response rate of 83.2%. According to IPAQ, accelerometer and steps/day, the majority of the respondents (22.0%, 55.1%, and 77.6%, respectively) were classified as sedentary. The agreement between physical activity level as determined by the accelerometer vs. the IPAQ (Kappa=-0.46 {95% CI -0.384,-0.536}, p=0.238) and the IPAQ vs. steps/day (Kappa =0.037 {95% CI 0.090,-0.016}, p=0.175) was not significant, but the agreement between physical activity level as determined by the accelerometer vs. steps/day was classified as fair (Kappa=0.296 (95% CI 0.392, 0.200}, p

    Hao Y, Razman R
    Front Public Health, 2023;11:1056191.
    PMID: 38026269 DOI: 10.3389/fpubh.2023.1056191
    BACKGROUND: Physical education (PE) class is an excellent way to improve moderate-to-vigorous intensity physical activity (MVPA). Increasing number of research has explored the children's PA based on movement during PE classes, but data for children with intellectual disability (ID) is still lacking.

    PURPOSE: The purpose of this study was to investigate the current status of MVPA levels of children with ID during PE classes in China, as well as differences of MVPA levels according to gender and grade.

    METHODS: Accelerometers were used to record MVPA levels of fifty-three children with severe ID from 9 to 16 years of age (mean age: 12.60 ± 1.66 years) during standard PE classes.

    RESULTS: The mean time spent in MVPA during PE classes was 8.00 ± 2.10 min, meaning only 22.88% of PE class time was spent in MVPA. As grade levels progresses, time spent in MVPA during PE classes tended to decrease; the fourth-grade children tended to spend more time in MVPA during PE classes compared with the fifth-grade and the sixth-grade (9.15 vs. 7.61 vs. 7.25 min, all p

    Numerous studies have shown the importance of physical activity in reducing the morbidity and mortality rates caused by cardiovascular disease (CVD). However, most of these studies emphasise little on the cumulative effect of CVD risk factors. Hence, this study investigates the association between physical exercise and cumulative CVD risk factors among adults in three different age groups.

    Nagammai T, Mohazmi M, Liew SM, Chinna K, Lai PS
    Qual Life Res, 2015 Aug;24(8):2031-7.
    PMID: 25648757 DOI: 10.1007/s11136-015-0933-7
    PURPOSE: To assess the validity and reliability of the Malay version of the Quality of Life (QOL) Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) in Malaysia.
    METHODS: The QUALEFFO-41 was translated from English to Malay and administered to 215 post-menopausal osteoporotic women ≥50 years who could understand Malay, at baseline and 4 weeks. The SF-36 was administered at baseline to assess convergent validity. To assess discriminative validity, patients with and without back pain were recruited.
    RESULTS: Confirmatory factor analysis showed that the QUALEFFO-41 had five domains. Good internal consistency was seen in all domains (0.752-0.925) except for the social activity domain (0.692). Test-retest reliability showed adequate correlation for all items (0.752-0.964, p < 0.001). Patients with back pain had significantly worse QOL compared with those without (back pain = 42.2 ± 10.9, no back pain = 33.3 ± 8.9; p < 0.001). The total QUALEFFO-41 score and the SF-36 physical and mental composite scores were significantly correlated (-0.636 and -0.529, p < 0.001, respectively).
    CONCLUSIONS: The Malay version of the QUALEFFO-41 was found to be a reliable and valid instrument to evaluate the QOL of osteoporotic patients in Malaysia. To enable the QUALEFFO-41 to be used in a multiracial population, further studies should look into validating other versions of the QUALEFFO-41 in Malaysia.

    Biomed Res Int, 2014;2014:123640.
    PMID: 24672778 DOI: 10.1155/2014/123640
    This study was performed to determine the effects of 8-week honey supplementation combined with different jumping exercise intensities on serum cortisol, progesterone, estradiol, and reproductive organs. Eighty-four 9-week-old female rats were divided into 7 groups: baseline controls (C0), sedentary group (C), 20 and 80 jumps per day (Ex(20J), Ex(80J)), honey (H), and combined honey with 20 and 80 jumps per day (HEx(20J), HEx(80J)) groups. Jumping exercise was performed at 5 days/week and honey was given at a dosage of 1 g/kg body weight/day for 7 days/week. The level of serum cortisol was higher in Ex(20J) and Ex(80J) compared to C. There was significantly lower value of serum cortisol in HEx(20J) compared to Ex(80J). Serum progesterone levels were significantly lower in Ex(20J) and Ex(80J) compared to C. However, serum progesterone levels were significantly higher in HEx(20J) and HEx(80J) compared to Ex(20J) and Ex(80J). Relative uterine weights were significantly greater in HEx(20J) compared to C and HEx(80J), respectively. There was no significant difference in estradiol level and relative ovarian weights among all the groups. Therefore, honey elicited beneficial effects in reducing the increase of cortisol and in increasing the reduce of progesterone levels induced by different intensities jumping exercise in female rats.

  8. The anthelmintic efficacy of natural plant cysteine proteinases against two rodent cestodes Hymenolepis diminuta and Hymenolepis microstoma in vitro
    Mansur F, Luoga W, Buttle DJ, Duce IR, Lowe A, Behnke JM
    Vet Parasitol, 2014 Mar 17;201(1-2):48-58.
    PMID: 24462509 DOI: 10.1016/j.vetpar.2013.12.018
    Little is known about the efficacy of cysteine proteinases (CP) as anthelmintics for cestode infections. We examined the effects of CPs on two rodent cestodes, Hymenolepis diminuta and H. microstoma in vitro. Our data showed that naturally occurring mixtures of CPs, such as those found in papaya latex, and relatively pure preparations of fruit bromelain, papain and stem bromelain, were active in vitro against both juvenile, artificially excysted scoleces, as well as against adult worms of both rodent cestodes. Significant dose-dependent reduction in motility, ultimately leading to death of the worms, was observed with both species, and against both freshly excysted scoleces and 14-day old pre-adult worms. The most effective was fruit bromelain (after 30 min of incubation of juvenile H. diminuta and H. microstoma IC50=63 and 74 μM, respectively, and for pre-adult worms=199 and 260 μM, respectively). The least effective was stem bromelain (after 30 min of incubation of juvenile H. diminuta and H. microstoma IC50=2855 and 2772 μM, respectively, and for pre-adult worms=1374 and 1332 μM, respectively) and the efficacies of papaya latex supernatant and papain were between these extremes. In all cases these values are higher than those reported previously for efficacy of CPs against intestinal nematodes, and in contrast to nematodes, all CPs were effective against cestodes in the absence of exogenous cysteine in incubation media. The CPs appeared to attack the tegument resulting in generalised erosion mainly on the strobila. The scolex was more resistant to CP attack but nevertheless some damage to the tegument on the scolex was detected.

    Asian Pac J Cancer Prev, 2014;15(1):39-44.
    PMID: 24528062
    BACKGROUND: This study aimed to provide an overview of lifestyle changes after breast cancer diagnosis and to examine the relationship between dietary and physical activity changes with weight changes in breast cancer patients. Women with breast carcinomas (n=368) were recruited from eight hospitals and four breast cancer support groups in peninsular Malaysia. Dietary and physical activity changes were measured from a year preceding breast cancer diagnosis to study entry. Mean duration since diagnosis was 4.86±3.46 years. Dietary changes showed that majority of the respondents had decreased their intake of high fat foods (18.8-65.5%), added fat foods (28.3-48.9%), low fat foods (46.8-80.7%), red meat (39.7%), pork and poultry (20.1-39.7%) and high sugar foods (42.1-60.9%) but increased their intake of fish (42.7%), fruits and vegetables (62.8%) and whole grains (28.5%). Intake of other food groups remained unchanged. Only a small percentage of the women (22.6%) had increased their physical activity since diagnosis where most of them (16.0%) had increased recreational activities. Age at diagnosis (β= -0.20, p= 0.001), and change in whole grain (β= -0.15, p= 0.003) and fish intakes (β= 0.13, p= 0.013) were associated with weight changes after breast cancer diagnosis. In summary, the majority of the women with breast cancer had changed their diets to a healthier one. However, many did not increase their physical activity levels which could improve their health and lower risk of breast cancer recurrence.

    Wafa SW, Hamzaid H, Talib RA, Reilly JJ
    J Trop Pediatr, 2014 Apr;60(2):161-3.
    PMID: 24213306 DOI: 10.1093/tropej/fmt093
    The present study examined objectively measured physical activity in Malaysian children and compared the differences in physical levels between obese and healthy weight children. Eighty-six obese children were matched for age and sex with 86 healthy weight children with median age 9.5 years. Habitual physical activity and sedentary behaviour were measured over 5 days using Actigraph accelerometers. Time spent sedentary was significantly higher in the obese group (90% vs. 86% of daytime; p = 0.001). Moderate-to-vigorous-intensity physical activity was significantly higher in the healthy weight group (1.2 vs. 0.7% of daytime, p < 0.001). In both healthy weight and obese children, physical activity levels were exceptionally low, although moderate-to-vigorous-intensity physical activity was significantly lower in the obese group than the healthy weight group. Efforts to prevent and treat obesity in Malaysian children will need a substantial focus on the promotion of reductions in sedentary behaviour and increases in physical activity.

    Apryani E, Hidayat MT, Moklas MA, Fakurazi S, Idayu NF
    J Ethnopharmacol, 2010 Jun 16;129(3):357-60.
    PMID: 20371280 DOI: 10.1016/j.jep.2010.03.036
    AIM OF THE STUDY: Mitragyna speciosa Korth from Rubiaceae family is a tropical plant indigenous to Southeast Asia particularly in Thailand, Peninsular of Malaysia and Indonesia. The leaves have been used by natives for their opium-like effect and cocaine-like stimulant ability to combat fatigue and enhance tolerance to hard work. However there is no scientific information about the effect of mitragynine on the cognitive performances. This study is designed to examine the working memory effects of mitragynine which is extracted from Mitragyna speciosa mature leaves.

    MATERIALS AND METHODS: The cognitive effect was studied using object location task and the motor activity in open-field test. Mitragynine 5, 10 and 15 mg/kg and were administered by intraperitoneal (IP) for 28 consecutive days and evaluated on day 28 after the last dose treatment. Scopolamine was used as the control positive drug.

    RESULTS: In this study there is prominent effects on horizontal locomotor activity was observed. Mitragynine significantly reduced locomotor activity in open-field test compared with vehicle. In object location task mitragynine (5, 10 and 15 mg/kg) did not showed any significances discrimination between the object that had changed position than the object that had remain in a constant position.

    CONCLUSION: Our results suggest that chronic administration of mitragynine can altered the cognitive behavioral function in mice.

  14. Antinociceptive and antiedematogenic activities of andrographolide isolated from Andrographis paniculata in animal models
    Sulaiman MR, Zakaria ZA, Abdul Rahman A, Mohamad AS, Desa MN, Stanslas J, et al.
    Biol Res Nurs, 2010 Jan;11(3):293-301.
    PMID: 19689990 DOI: 10.1177/1099800409343311
    The current study was performed to evaluate the antinociceptive and antiedematogenic properties of andrographolide isolated from the leaves of Andrographis paniculata using two animal models. Antinociceptive activity was evaluated using the acetic acid- induced writhing and the hot-plate tests, while antiedematogenic activity was measured using the carrageenan-induced paw edema test. Subcutaneous (s.c.) administration of andrographolide (10, 25, and 50 mg/kg) did not affect the motor coordination of the experimental animals but produced significant (p < .05) antinociceptive activity when assessed using both tests. However, 2 mg/kg naloxone failed to affect the 25 mg/kg andrographolide activity in both tests, indicating that the activity was modulated via nonopioid mechanisms. Furthermore, andrographolide showed significant (p < .05) antiedematogenic activity. In conclusion, the results obtained suggest that andrographolide has antinociceptive and antiedematogenic activities; it may be useful for treating pain and inflammation once human studies are conducted.

    Stress, 2006 Mar;9(1):53-60.
    PMID: 16753933
    In this study, the hypothesis was tested that behaviour of rats under the open field test condition and effects of subsequent acute stress relate to conformational properties of the main plasma carrier protein, albumin.To evaluate albumin properties, fluorescence intensity of a molecular probe CAPIDAN (N-carboxyphenylimide of dimethylaminonaphthalic acid) at N (at pH 7.4) and F (at pH 4.2) albumin conformations was measured and the N-F signal ratio was calculated. The data obtained showed that CAPIDAN fluoresces selectively from albumin in rat serum and its fluorescence is sensitive to binding of fatty acids and some other ligands to albumin. Behaviour of 78 Wistar male rats was characterized from the fraction of time taken for exploratory and ambulatory activity during the open field test. In rats not subjected to stress (n = 40), a negative correlation was revealed between open field activity and CAPIDAN N-to-F ratio for albumin (r = - 0.55, p < 0.0005). In the group of rats subjected to acute stress (immobilization plus stochastic electrocutaneous stimulation) the correlation between behavioural activity and the albumin conformational properties was significantly positive (r = 0.59, p < 0.0001): the CAPIDAN albumin fluorescence ratio increased in the highly active rats and decreased in the low-activity rats. The mechanisms of the observed effects may involve differences in nonesterified fatty acid production during stress.

    Clin Exp Pharmacol Physiol, 1999 7 1;26(5-6):444-8.
    PMID: 10386236
    1. This study was carried out to determine the effect of short-term and long-term ingestion of glycyrrhizic acid on the response to 2 h of restraint stress by measuring locomotor activity and plasma corticosterone levels. 2. Male Sprague-Dawley rats were randomly assigned into four groups, each group having eight rats. Group 1 (control) was given ordinary tap water, while groups 2 (short term), 3 and 4 (both long term) were given tap water containing 1 mg/mL glycyrrhizic acid to drink for 10 days, 4 weeks and 9 weeks, respectively. All the rats were subjected to 2 h of restraint stress and the locomotor activity assessed using an activity test in an open field arena followed by blood sampling to determine the plasma corticosterone level. These procedures were repeated daily for 14 days. 3. The basal locomotor activity scores for rats given glycyrrhizic acid for 10 days or 4 weeks were similar to those of controls; however, that of the rats treated long term with glycyrrhizic acid was significantly lower (21.0 +/- 3.0 squares crossed; P < 0.0005). Following the first period of restraint stress there was a highly significant decrease in locomotor activity, which remained significantly lower until the seventh and subsequent periods, indicating an adaptation to the repeated stress had occurred. Although the decrease in locomotor activity was partially blocked and adaptation to repetitive stress was enhanced in the rats given glycyrrhizic acid for 10 days, this was not seen in rats treated with glycyrrhizic acid for 4 or 9 weeks. The corticosterone levels in control rats were significantly elevated for 4-5 days following the exposure to repetitive stress but decreased gradually from day 7 onwards. However, both short- and long-term glycyrrhizic acid-treated rats had higher plasma corticosterone levels than the controls (P < 0.05). 4. In conclusion, repetitive restraint stress caused decreased locomotor activity associated with increased plasma corticosterone levels, both of which, in normal rats, decreased with adaptation to stress. The stress response was partially blocked and adaptation enhanced in rats given glycyrrhizic acid for 10 days, but not in rats given glycyrrhizic acid for 4 and 9 weeks. Glycyrrhizic acid ingestion caused high plasma corticosterone.

    Curcuminoids derived from turmeric rhizome have been reported to exhibit antinociceptive, antioxidant and anti-inflammatory activities. We evaluated the peripheral and central antinociceptive activities of 5-(3,4-dihydroxyphenyl)-3-hydroxy-1-(2-hydroxyphenyl)penta-2,4-dien-1-one (DHHPD), a novel synthetic curcuminoid analogue at 0.1, 0.3, 1 and 3 mg/kg (intraperitoneal), through chemical and thermal models of nociception. The effects of DHHPD on the vanilloid and glutamatergic systems were evaluated through the capsaicin- and glutamate-induced paw licking tests. Results showed that DHHPD significantly (p < 0.05) attenuated the writhing response produced by the 0.8% acetic acid injection. In addition, 1 and 3 mg/kg of DHHPD significantly (p < 0.05) reduced the licking time spent by each mouse in both phases of the 2.5% formalin test and increased the response latency of mice on the hot-plate. However, the effect produced in the latter was not reversed by naloxone, a non-selective opioid receptor antagonist. Despite this, DHHPD decreased the licking latency of mice in the capsaicin- and glutamate-induced paw licking tests in a dose response manner. In conclusion, DHHPD showed excellent peripheral and central antinociceptive activities possibly by attenuation of the synthesis and/or release of pro-inflammatory mediators in addition to modulation of the vanilloid and glutamatergic systems without an apparent effect on the opioidergic system.
