    Spirituality and mental adjustment have been widely adopted as coping strategies among women with breast cancer. Little information was available locally on the use of spirituality and mental adjustment as coping mechanisms to fight breast cancer. A cross-sectional study was conducted to assess spirituality and mental adjustment as coping strategies and its association with socio demographic data on 216 women with breast cancer. The Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp) and Mental Adjustment to Cancer (MAC) Scales were used to assess spirituality and mental adjustment. Negative correlation between spiritual well-being and helplessness/hopelessness (r=-0.690; p=0.000), anxious preoccupation (r=-0.277; p=0.000) and avoidance (r=-0.235; p=0.000) and positive correlation between spiritual well-being and fighting spirit (r=0.668; p=0.000) were identified. Socio-demographic factors such as race (p=0.000), religion (p=0.000), academic qualification (p=0.004) and type of surgery (p=0.016) revealed significant relationship with spiritual well-being. Fighting spirit, hopelessness/helplessness and anxious preoccupation also yielded significant relationship with race (p

    Cervical cancer is the seventh most common cancer among women in Iraq. This study aimed to assess the factors influencing Pap smear practice among married primary school teachers in Diyala City, Iraq. A total of 222 teachers (aged 20 years to 63 years) residing in Diyala City were enrolled in a cross sectional study from 1st August till 30th September 2012. The sampling method was a self-administered survey using a multistage sampling technique. The prevalence of Pap smear practice was very low (12.6%). Relatives and friends were the main source of information about the Pap smear test for more than one third (41.9%) of the respondents. However, the medical doctor’s advice was the most important reason for undergoing a Pap smear test in more than two third (60.7%) of respondents. Only 32.4% of the teachers have good knowledge about cervical cancer and Pap smear test, but 76.1% of them showed a positive attitude toward learning about cervical cancer and Pap smear. Based on multiple logistic regression analysis results only the husband’s encouragement (p= 0.003, prevalence odds ratio [POR] = 0.256, 95%CI 0.10-0.63) was significantly associated with Pap smear practice. A more effective educational program is needed to educate Iraqi women about cervical cancer and screening tests, including Pap smear.

    Smoking among school children is becoming a serious problem in developing countries, including Bangladesh. The early initiation of smoking needs urgent intervention to protect this vulnerable group and preventing them to be addicted. This study aims to determine the age at initiation of smoking and factors affecting it. A two-stage cluster sampling was used with a selection of schools on probability proportional to enrolment size followed by stratified random sampling of government and private schools and then a random start in classes VIII, IX and X of each school targeting the students aged 13 years and above. Data collected from secondary school students using self-administered structured questionnaire. All analyses were performed with SPSS version 20.0. Missing value was treated by multiple imputations. A total of 6877 data were analysed in which 84.7% were non-smoker, 9.5% were ever smoker and 5.8% were current smokers. Among the ever smoker (n=823), 38% were current smokers, 56.5% former and 5.5% were recent quitters. The mean (SD) age at initiation of smoking was 10.9 (0.2) years. Multinomial regression analysis revealed that class grade, peer pressure and offered free cigarette appeared to be significant predictors of smoking initiation (p0.05). Promotion of smoking resistance skills among children and teens through comprehensive approaches designed to enhance general personal competence by teaching an array of personal and social life skills is recommended.

    Women and elderly are often linked to several disadvantages and constraints in many aspects of life. The scenario could be even worse for an elderly woman. Participating in leisure has proven to be beneficial for elderly in general. Yet little is known about the pattern of leisure and constraints faced by elderly women in order for them to pursue leisure activities. This study aims to explore the various leisure constraints faced by the elderly women. A total of 20 elderly women were involved in this study, which were selected purposively and also by snowballing technique. An in-depth interview was conducted with each respondent lasted approximately 15 to 30 minutes. The identified constraints were categorized into three main themes, which were structural, intrapersonal and interpersonal constraints. Among factors that had been identified were preoccupation with domestic affairs, the unavailability of appropriate space or area to perform desired leisure activities, lack or unavailability of transportation, safety issue, misperceptions that being old should focus on religious activity and becoming effortless, domestic activities are comparable to exercise and lacking of elderly people to perform certain activities together. In view of the modifiable nature of most of constraints faced by the elderly women to pursue leisure activities, necessary actions should be taken by the relevant authorities in tackling the constraints and at the same time developing a more active and healthy elderly women society. The right of the elderly women and women in general should be acknowledged, including their desire to actively involve in certain leisure activities. They should also appropriately educate on the importance of leisure and involvement in other type of leisure activities other than religious activities.

    Diversified leisure involvement pose various health benefits to the elderly population. However, some elderly are too focus on doing a particular type of activity during their leisure time such as religious activity. This study aims to explore factors that could possibly contribute to the higher involvement in religious activity among the Malay ethnic elderly in Malaysia. In depth interviews were conducted, involving a total of 20 elderly aged 60 years and above with stratification by background characteristics. Each interview was conducted for an average of 15 to 30 minutes. They were purposively selected from two health clinics located in two different districts in the state of Selangor, representing an urban and a rural area. Majority of the elderly interviewed perceived that by engaging in religious activities such as prayer and reciting the Holy Quran or old Islamic scripture gives them serenity or calmness. Additionally, they also felt that involvement in such activities is very synonymous with being old and therefore one should be actively involved in religious activities with increasing age. In view of the lack of diversity of leisure involvement among the elderly and the passive and solitary nature of some of the religious activities, the elderly should be made aware of the importance of participating in other types of leisure activities especially physical activities. Although, they gain spiritual and social benefits from involving in religious activities, they also need to perform other form of activities that can improve the physical health status.

    Hospital information systems have evolved with the recent widespread, involving technology and target functions, and this involves the critical computer systems from multiple perspectives. Healthcare organizations increasingly use information technology as a basis for improving productivity and user satisfaction. A research had been done about the level of satisfaction in using the Hospital Information System. Data was obtained by using a set of questionnaires that have been tested for reliability and validity. The staff are comprised of two (2) categories: Nurses (community nurses / Head nurse / staff nurse, nurse managers and others) while the second category consists of administrative officers (administrative officers, administrative assistants and clerks) in selected departments. Variables consist of sociodemographic factors, occupational factors and perception factors. A total of 152 respondents identified using stratified sampling method. The factors studied were age, gender, marital status, level of qualifications, length of service, knowledge of the system, attitude towards the use of the system, behavioral intention to use the system and compatibility with work. Majority of respondents were females (88.2%). The level of satisfaction among the staff in using the hospital information system is high (88.8%) compared to the dissatisfied staff in UKMMC (11.2%). In overall, the staffs in UKMMC are satisfied using the hospital information system available now but there are always a room for improvement so that the system can be used more intensively.

    Occupational stress is one of the major health hazards among blue and white-collar workers. However there is no data on occupational stress among white-collar workers in Iran. Aim of this study was to investigate occupational stress among white collar employees in Esfahan Steel Company organization (ESCO), Iran. A cross-sectional survey was conducted through face to face interview using validated standardized questionnaire on occupational stress among 200 white-collar workers from ESCO who agreed to participate in the study, the response rate of participation was 100%. The logistic regression test was used to determine significant associated factors of occupational stress among the study sample.. It is found that among the six items measuring source of stress, the highest source of stress related to economic problem, 117 (59.7%). The statistical analysis showed sources of stress such as task type (p=0.0001), economic problem (p=0.0001), work environment (p=0.0001) and children problem (p=0.05) were significantly associated with having stress among the workers. We found that around half of the white collar workers were under stress at ESCO. Main sources of the occupational stress of white colour workers related to their work environment, economic problem; task type, and related their children.

    Adherence to antiretroviral therapy (ART) plays an important role in the treatment outcomes of human immunodeficiency virus (HIV) infection. Poor adherence would result in failure to prevent viral replication as well as an increased risk of developing drug resistance. Adherence to a life long treatment such as antiretroviral therapy is usually a complicated issue that requires careful and continuous collaboration of patient, family and healthcare provider. The objective of this study was to assess adherence to antiretroviral therapy and its associated factors among people living with HIV. This is a health facility-based cross sectional study conducted among adults’ people living with HIV in Omdurman HIV/AIDS centre, Sudan. Data was collected through direct interview using semi-structured questionnaire. There were only 144/846 (17.02%) who adhered to antiretroviral therapy as prescribed by their doctors. The remaining 51.18% were taking the therapy but not regularly, 31.21% were taking it but currently not and 0.59% stated that they have never taken any antiretroviral therapy. Factors associated with poor adherence that have been identified include female gender (Adj. OR = 3.46 (95%CI: 1.46-8.21), P = 0.005), younger age (Adj. OR = 1.14 (95%CI: 1.02-1.28), P = 0.022), being unemployed (Adj. OR = 5.94 (95%CI: 1.51-23.40), P = 0.011), those who were divorced, separated or widowed (Adj. OR = 11.35 (95%CI: 1.74-73.96), P = 0.011) and respondents who perceived that their health status is poor (Adj. OR = 5.21 (95%CI: 1.44-18.81), P = 0.012) or very poor (Adj. OR = 4.04 (95%CI: 1.27-12.81), P = 0.018). Educational level and social support against HIV-related stigma and discrimination were not significantly associated with adherence. Adherence to antiretroviral therapy among the respondents is very poor. Urgent interventions based on modifiable factors and mainly targeting females and younger age group are needed to improve adherence to antiretroviral therapy among people living with HIV.

    The unstable living situation in Iraq in the last 10 years after 2003 war affected the daily life of most Iraqis, and especially the children. The objective of this study was to explore the effects of an unstable living environment on children’s health. A community-based qualitative study was done to collect data from 20 mothers of children (age 7 to 8years old) through in-depth interview (IDI). Data was recorded using tape recorders and was later transcribed and analyzed using qualitative thematic analysis techniques. The majority of mothers interviewed said the past nine years of unstable security in the capital had affected their daily life; some mothers also expressed concern about their child’s nutritional status, their eating habits during the school day, and the unhealthy food being sold at school canteens. As a conclusion, the unstable living situations in Baghdad city after the last war had affected the cognitive and nutritional development of children. More precautions should be taken by parents to ensure their children safety in the future.

    Falls are the most common injury causing death or long term disability particularly among children. This study aimed to identify the risk factors of the unintentional injuries due to falls in children aged less than five years in Yemen. This cross sectional study enrolled a total of 439 children under five years old from the emergency department of 6 hospitals in Sana'a city. Multistage sampling was used to select six hospitals from public and private sectors in Sana'a city. Face to face interviews were conducted by using a structured questionnaire. Simple logistic regression and multiple logistic regression were used in the analysis. The prevalence of falls among children under five years old was 21.2%. In the multivariate analysis, factors associated with falls among children were young mother (aOR= 0.9, 95% CI 0.81-0.91), working of mother (aOR= 4.5 95% CI 2.40-7.65), frequent family social gatherings (aOR= 2.7, 95% CI 1.54-4.61), number of children at home (aOR= 2.6, 95% CI 1.43-4.64), chewing khat by father (aOR= 2.4, 95% CI 1.38-4.10), presence of staircase in the house (aOR= 2.1, 95% CI 1.24-3.70), number of rooms at home (aOR= 2.2, 95% CI 1.17-3.99) and disabled children (aOR= 3.3, 95% CI 1.20-9.27). In the study, socio-economic and cultural factors such as family gathering and chewing khat were associated with home fall injury among children under 5 years old in Yemen. Health promotion program should take place to reduce the occurrence of fall injury.

    Thalassaemia carriers are common in the Asian region including Malaysia. Asymptomatic patients can be undiagnosed until they present for their antenatal visits. Devastating obstetric outcome may further complicate the pregnancy if both parents are thalassaemia carriers leading to hydrophic fetus due to haemoglobin Bart’s disease. However in certain cases where unexplained hydrops fetalis occur in parents with heterozygous thalassaemia carrier,mutated α genes should be suspected. We report a twenty-nine year old woman in her third pregnancy with two previous pregnancies complicated by early neonatal death at 21 and 28 weeks of gestation due to hydrops fetalis. DNA analysis revealed the patient to have heterozygous (--SEA) α-gene deletion, while her husband has a compound heterozygosity for α3.7 deletion and codon 59 (GGC ➞ GAC) mutation of the α-gene. This mutation, also known as hemoglobin Adana, can explain hydrops fetalis resulting from two alpha gene deletions from the patient (mother) and a single alpha gene deletion with mutation from the father. The third pregnancy resulted in a grossly normal baby boy with 3 α-gene deletions (HbH disease). We postulate that, in view of heterogenisity of the α-thalassaemia in this patient with severely unstable haemoglobin Adana chains from her husband, there will be a 25% possibility of fetal hydrops in every pregnancy.

    Aloe emodin, an anthraquinone of Aloe barbadensis Miller has been shown to have more cytotoxic effect in
    different kinds of human cancer cell lines compared to normal. Accordingly, we found it to selectively inhibit
    the proliferation of oestrogen-receptor-positive-(ER+)-breast cancer cells, MCF-7; but not controls cells,
    MCF-10A. However, its precise mechanism is not well understood. Several studies have shown that there is
    evidence of increased intracellular calcium (Ca2+), both at early and late stage of apoptosis which associated
    with the down-regulation of ERK1/2 proliferative pathway. Therefore, we aim to elucidate the involvement
    of intracellular Ca2+ in aloe emodin induced apoptosis on MCF-7. Apoptotic morphological changes were
    observed under fluorescence microscope. The involvement of cytoplasmic Ca2+ and MAPKs were investigated
    using Fluo-4 intracellular Ca2+ imaging and QuantiGene 2.0 Plex assay, respectively. IC50 of aloe emodin
    (80 μM) at 72 hours incubation was used. Data were evaluated using the one-way or two-way ANOVA tests.
    Our results indicated that aloe emodin at IC50 80µM induced apoptosis on MCF-7 through the association of
    intracellular Ca2+ signalling. This observation include a significant increased (p

    We had reviewed the current practice in stocks market analysis where stock is represented by its closing price, and then found that this approach may be misleading. In actuality, in the daily activity of stocks market, stock is represented by four prices, namely opening, highest, lowest, and closing prices. Thus, stock is a multivariate time series of those four prices and not a univariate time series of closing price only. In this paper all four prices will be considered. Then, the notion of multivariate time series similarity among stocks will be developed as a generalisation of univariate time series similarity. The results are used to construct stocks network in multivariate setting. To filter the economic information contained in that network, the standard tools in econophysics is used. Furthermore, the topological properties of stocks are analysed by using the most common centrality measures. As an example, Bursa Malaysia data are investigated and we show that the proposed approach can better figure out the real situation compared to the current one.

    Marine mammal searches were opportunistically conducted during the East Coast Johor Scientific Expedition (ECJSE) on 21-30 May 2012, on a live-on-board (LOB) diving vessel, MV BLACK PEARL. The expedition was designed mainly to survey coral reef ecosystems and water quality. Daylight visual observations of the sea were undertaken during sailing and stopping/anchored from the most upper open-deck of the vessel. The survey resulted in two sightings of long-beaked common dolphins (Delphinus capensis), each at Pulau Aur and Pulau Tinggi. Both observations were brief (< 5 minutes) and were made when the vessel was anchored. Based on anecdotal evidences, skeletal remains and previous surveys, the vulnerable dugong, Indo-Pacific bottlenose, Indo-Pacific humpback, Irrawaddy and long-beaked common dolphins, the false killer and pygmy killer whales, and the baleen whales are known to occur in the East Coast Johor waters, at least occasionally. The low sighting rate with marine mammals during this survey is highly likely caused by the survey design and also may be due to the environmental conditions and ecological factors. Dedicated and periodical boat and aerial surveys for marine mammals need to be conducted to determine species diversity and to understand the seasonality, habitat use, and social interactions of the marine mammal populations in the area. The findings will be most useful for marine park and fisheries authorities to plan conservation management strategies for marine mammals and promote their conservation through eco-tourism activities.

    This study was conducted to prepare a mixed matrix membrane (MMM) and to test the performance of the prepared MMM for CO2 and CH4 gas separation. MMM containing polyethersulfone (PES) and multi-walled carbon nanotubes (MWCNTs) was prepared by a dry-wet phase inversion technique using a pneumatically-controlled membrane casting machine. The surface modification was performed on MWCNTs in order to enhance the selectivity of CO2/CH4. The surface modification of MWCNTs using chemical and physical approaches has been adopted. Mixed acid (HNO3/H2SO4) and β-CD were used for chemical and physical approaches, respectively. Effects of surface modification on MWCNTs/PES MMM were investigated. MWCNTs/PES MMMs were characterised using scanning electron microscopy (SEM), the Fourier Transform Infrared (FT-IR) spectroscopy and pure gas permeation test. The permeability and selectivity, which are the parameters describing membrane performance were calculated via the data obtained from pure gas permeation test with the feed pressure difference from 3 to 7 bars. In this study, surface modified MWCNTs/PES MMM using mixed acid and β-CD has successfully enhanced the CO2/CH4 selectivity by 40.6% compared to that of neat PES.

    Elevated glucocorticoid levels during stressed conditions have been demonstrated to impair reproductive function in rats. In our previous study investigating the dose-related effects of corticosterone (CORT) on the fertilising capacity of epididymal sperm in surgically-manipulated rats, we found that 25 mg/kg/day of CORT given subcutaneously for seven consecutive days significantly decreased the number of implantation sites and increased intrauterine embryonic loss compared to controls. Based on these findings, the current study aims to elucidate the possible mechanisms of action of CORT-induced stress on impaired sperm fertility in rats. Results of the present study showed that compared to controls, 25 mg/kg/day of CORT given subcutaneously for 7 consecutive days significantly increased the level of plasma malondialdehyde (MDA) with corresponding attenuated levels of superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) activities. Plasma adrenocorticotropin (ACTH) and testosterone levels were also found to be decreased in CORTtreated rats. These findings suggest that CORT-induced oxidative stress and exert an inhibitory effect at the hypothalamic-pituitary-gonadal (HPG) axis, as evidenced by increased lipid peroxidation, reduced enzymatic antioxidant activities, and decreased testosterone production. These subsequently result in decreased fertilising capacity of epididymal sperm leading to poor pregnancy outcomes.
