    A cross sectional descriptive study on breast feeding practices in an urban clinic was conducted among 136 mothers aged between 21-49 years who were interviewed using a questionnaire. Malays constituted 61% of the respondents, Chinese 22.8% and Indians 16.2%. Mojority of these were working mothers and although the initiation of breastfeeding was high (99.3%), exclusive breastfeeding was only 12.5%. A large proportion (33.8%) dtopped prior to 3 months. Majority of the Chinese mothers (61.3%) stipped before 3 months as compared to the Indian (40.9%) and Malay (21.7%) mothers (p<0.001). Mean age of introducing complementary foods at 3 months is below the accepted age of 4 to 6 months for weaning. Ever-breast feeding rate is high in this urban setting but more efforts are needed to effect a higher rate of exclusive breastfeeding and longer duration of breastfeeding.

    Malaysia enjoys a comprehensive range of health services, the government being committed to the principles of universal access to high quality health care, which the Ministry of Health provides through a wide variety of nation wide network of clinics and hospitals. One of the major problems is the availability of comprehensiveness and quality of health care in remote health centres. When patients are transferred from the health centres to the hospitals for further treatment, this not only incurs inconvenience to the patients and their family but also increases the cost to the health care system. Teleprimary care is one of the tools to overcome this problem. The doctors in the remote clinics are able to discuss the problem cases through teleconsultation with the doctors and specialist in the hospitals using an audiovisual system to provide better care in the health centers without transferring the patients to the hospitals. Only the essential and needy patients are referred to the hospitals. This has not only reduced the number of patients referred to the hospitals but it has reduced the cost to the health care system. It has also provided a more comprehensive care to the patients in the health centres. The doctors in the health centers are also provided training and are also updated on the latest in medicine. This method of training has made doctors in the health centers more efficient and satisfied.

    Telemedicine is fast becoming popular in many countries in the world. It has several advantages such as being cost saving and providing better access to health care in the remote areas in many parts of the world. However, it has some disadvantages as well. One of the major problems is the problem of patients' rights and confidentiality in the use of telemedicine. There are no standard guidelines and procedures in the practice of telemedicine as yet. Both the patient and the physician are unsure of the standard of practice and how to maintain confidentiality. The patient is uncertain as to how to protect her/his rights in the use of telemedicine. The issue of litigation is also unclear as to where the physician is practicing when he/she uses telemedicine. Is she/he practicing in the country where the patient is or is the physician practicing in the country of her/his origin? These issues need to be addressed urgently so that telemedicine will have standards of ethical practice and the patient's rights and confidentiality will be protected.

    Cholera has been in existence in Sarawak for many years and since 1873 many major epidemics have occurred. The epidemics usually occur during the dry months of May, June and July and the population affected are those in coastal areas. As in other outbreaks the areas affected were those which had poor environmental sanitation, poor water supply, poor refuse disposal and indiscriminate disposal of faeces. Malays are more affected as in Peninsular Malaysia outbreaks. The classical biotype was common prior to 1961. In later years the El Tor (biotype) has been responsible for most outbreaks.

    This community based cross-sectional study examined the prevalence and factors associated with depression among urban poor in Peninsular Malaysia. The Patient Health Questionnaire (PHQ-9) was used to determine the presence or absence of depression. The prevalence of depression among the urban poor was 12.3%. Factors significantly associated with depression included respondents under 25 years old, male gender, living in the area for less than four years and those who do not exercise regularly. It is important to identify individuals with depression and its associated factors early because depression can severely affect the quality of life.

    BACKGROUND: Facebook and mobile texting are prevalent in the lives of almost every student. However, little is known about the relationship between Facebook usage or mobile texting and their impacts on health amongst undergraduate dental students. In this study, excessive Facebook use and excessive mobile texting were studied as they relate to impacts on health.

    MATERIALS AND METHODS: A cross-sectional study was conducted at a private university in Malaysia. A total of 188 undergraduate dental students were interviewed using a pre-tested and self-rated questionnaire. Data collected from participants were analysed using SPSS version 18.0. Chi-square test, Fisher's exact test and multiple logistic regression analyses were applied to study the relationship between explanatory variables and excessive Facebook use and excessive mobile texting.

    RESULTS: The prevalence of excessive Facebook use and excessive mobile texting amongst undergraduate dental students was found to be 33.2% and 33.0%, respectively. According to a multivariate analysis, texting habits, such as the presence of daytime sleepiness after texting late at night (aOR = 2.682, 95% CI = 1.142-6.301) and the presence of anxious feelings if students failed to receive a timely response (aOR = 3.819, 95% CI = 1.580-9.230), were determined to be significant predictors of excessive mobile texting. Excessive Facebook use was found to be significantly related to three variables as follows: fewer numbers of close friends (aOR = 2.275, 95% CI = 1.057-4.898), the checking of updates on the Facebook walls of their friends (aOR = 2.582, 95% CI = 1.189-5.605) and the absence of active and vigorous feelings during Facebook use (aOR = 3.401, 95% CI = 1.233-9.434).

    CONCLUSIONS: Approximately one-third of undergraduate dental students in this study experienced excessive Facebook use and/or excessive mobile texting. Health education and promotion should be instituted to create awareness, whilst students should be advised to practise self-control with respect to both mobile texting and Facebook usage.

    BACKGROUND:
    Dyspepsia is a common, chronic condition but medical consultation rates for symptoms remain variable. We aimed to examine two populations with varied health-care provision to determine predictive factors for dyspepsia-related consultation.

    METHODS:
    A cross-sectional, population-based study in both an urban and a rural community within a single Asian country was conducted. Details on dyspepsia-related consultation rates over a fixed period and independent factors influencing them were identified.

    KEY RESULTS:
    A total of 4039/5370 (75.2%) adults from representative rural and urban areas in this country agreed to participate in the study. Although mean ages of respondents were similar (40.4years), the demographics of both populations varied in terms of gender (62.7% female, rural vs 55.7% female, urban, P<0.0001), marital status (75.4% rural vs 70.5% urban, P=0.002), ethnicity, (79% Malay rural vs 45.3% Malays urban, P<0.0001) and socio-economic status (professional occupation 7.1% rural vs 47.3% urban, P<0.0001). Dyspepsia-related consultation rates were found to be higher among rural compared to urban adults (41.4%vs 28.7%, P<0.0001). Over-the-counter medication consumption was higher among urban compared to rural dyspepsia sufferers (n=157 vs n=35, P<0.0001). Following logistic regression, rural population (OR 3.14, 95% CI=1.65-6.0), low quality of life (OR 1.90, 95% CI=1.17-3.10), and self-medication (OR 0.40, 95% CI=0.25-0.62) were found to independently predict dyspepsia-related consultation.

    CONCLUSIONS & INFERENCES:
    Dyspepsia-related consultation varied significantly between urban and rural communities. Factors within the rural population, self-medication practices, and a low quality of life independently influenced dyspepsia-related consultation.

    BACKGROUND: Ethical behavior and professionalism is an ideal characteristic required of medical students and included as 'must achieve' and critical aspect of medical students' curriculum. This study proposes to determine the perceived unethical and unprofessional behavior among medical students in a private medical university from year 1 to year 5 of the medical curriculum.

    METHODS: A cross-sectional study was conducted among year 1 to year 5 medical students in a private medical university. A self-administered questionnaire was used with the 3 major domains of professionalism and ethics i.e. discipline plagiarism and cheating.

    RESULTS: A total of 464 respondents responded to the survey and they included medical students from year 1 and year 2 (pre-clinical) and years 3-5 (clinical years). Majority of the students, 275 (59.2%) answered that they had not seen any form of unethical behavior among other students. The females seem to have a larger number 172(63%) among the same gender compared to the males. Majority 352 (75%) of them had not heard of the 'Code of Professional Conduct by the Malaysian Medical Council'. About fifty three (53.1%) of the students answered that the training was sufficient.

    CONCLUSIONS: This study showed that the perception of unethical behavior was 58.8% in the 1st year (pre-clinical) and it increased to 65.2% in the 5th year (clinical). The 3 main discipline issues were students do not show interest in class (mean 2.9/4), they are rude to other students (mean 2.8/4) and talking during class (mean 2.6/4). Despite the existence of unethical behavior among the students majority of them (71.7%) claimed that they had adequate training in ethics and professionalism. It is proposed that not only the teaching of ethics and professionalism be reviewed but an assessment strategy be introduced to strengthen the importance of professionalism and ethics.

    BACKGROUND: Studies have revealed that a higher proportion of women affected by cervical cancer are from some minority groups of immigrant women. Hence, this study was conducted to assess Yemeni immigrant women's awareness of cervical cancer and its associated socio-demographic factors.

    METHODS: A cross-sectional study was conducted among 370 Yemeni women in Selangor and Kuala Lumpur, Malaysia. Data on the awareness of symptoms/signs, risk factors, and screening programme were collected using Cervical Cancer Awareness Measurement (Cervical CAM) questionnaire.

    RESULTS: More than 74% of the study participants were unable to recall any warning symptoms/signs, and 73% were unable to recall any risk factors. The factors associated with the awareness of symptoms and risk factors were age (95% CI 4.22-5.22, p = 0.039), marital status (95% CI 4.05-7.87, p = 0.021), employment (95% CI 3.89-5.77, p = 0.046) and the number of children (95% CI 5.33-6.54, p = 0.041).

    CONCLUSION: The findings underline the need for public awareness campaigns to improve public awareness of cancer symptoms and risk factors among underserved communities.

    BACKGROUND/AIMS: The economic impact of dyspepsia in regions with a diverse healthcare system remains uncertain. This study aimed to estimate the costs of dyspepsia in a rural and urban population in Malaysia.

    METHODS: Economic evaluation was performed based on the cost-of-illness method. Resource utilization and quality of life data over a specific time frame, were collected to determine direct, indirect and intangible costs related to dyspepsia.

    RESULTS: The prevalences of dyspepsia in the rural (n = 2,000) and urban (n = 2,039) populations were 14.6% and 24.3% respectively. Differences in socioeconomic status and healthcare utilisation between both populations were considerable. The cost of dyspepsia per 1,000 population per year was estimated at USD14,816.10 and USD59,282.20 in the rural and urban populations respectively. The cost per quality adjusted life year for dyspepsia in rural and urban adults was USD16.30 and USD69.75, respectively.

    CONCLUSIONS: The economic impact of dyspepsia is greater in an urban compared to a rural setting. Differences in socioeconomic status and healthcare utilisation between populations are thought to contribute to this difference.

    Little is known about the relationships between adverse health effects and unhealthy behaviors among medical students using Facebook. The aim of this study was to determine the associations between adverse health effects and unhealthy behaviors with Facebook use. A cross-sectional study was conducted in a private university in Malaysia among 316 medical students. A self-administered questionnaire was used. It included questions on sociodemographics, pattern of Facebook use, social relationship, unhealthy behaviors, and health effects. Mean age was 20.5 (±2.7) years. All students had a Facebook account. The average daily Facebook surfing hours were 2.5 (±1.7). Significant associations were found between average hours of Facebook surfing and the following factors: isolation from family members and community, refusing to answer calls, musculoskeletal pain, headache, and eye irritation (P < 0.005). The average hours spent on Facebook were significantly associated with holding urination and defecation while online, surfing Facebook until midnight, and postponing, forgetting, or skipping meals (P < 0.005). The average hours spent on Facebook were associated with adverse health effects and unhealthy behaviors among medical students, as well as social isolation from the family and community.

    In this study, a novel nanohybrid composite containing nitrogen-doped multiwalled carbon nanotubes/carboxymethylcellulose (N-MWCNT/CMC) was synthesized for supercapacitor applications. The synthesized composite materials were subjected to an ultrasonication-mediated solvothermal hydrothermal reaction. The synthesized nanohybrid composite electrode material was characterized using analytical methods to confirm its structure and morphology. The electrochemical properties of the composite electrode were investigated using cyclic voltammetry (CV), galvanic charge-discharge, and electrochemical impedance spectroscopy (EIS) using a 3 M KOH electrolyte. The fabricated composite material exhibited unique electrochemical properties by delivering a maximum specific capacitance of approximately 274 F g-1 at a current density of 2 A g-1. The composite electrode displayed high cycling stability of 96% after 4000 cycles at 2 A g-1, indicating that it is favorable for supercapacitor applications.

    Nitrogen-doped multiwalled carbon nanotubes (N-MWCNTs) have been used to fabricate nanostructured materials for various energy devices, such as supercapacitors, sensors, batteries, and electrocatalysts. Nitrogen-doped carbon-based electrodes have been widely used to improve supercapacitor applications via various chemical approaches. Based on previous studies, CuO@MnO2 and CuO@MnO2/N-MWCNT composites were synthesized using a sonication-supported hydrothermal reaction process to evaluate their supercapacitor properties. The structural and morphological properties of the synthesized composite materials were characterized via Raman spectroscopy, XRD, SEM, and SEM-EDX, and the morphological properties of the composite materials were confirmed by the nanostructured composite at the nanometer scale. The CuO@MnO2 and CuO@MnO2/N-MWCNT composite electrodes were fabricated in a three-electrode configuration, and electrochemical analysis was performed via CV, GCD, and EIS. The composite electrodes exhibited the specific capacitance of ~ 184 F g-1 at 0.5 A g-1 in the presence of a 5 M KOH electrolyte for the three-electrode supercapacitor application. Furthermore, it exhibited significantly improved specific capacitances and excellent cycling stability up to 5000 GCD cycles, with a 98.5% capacity retention.
