    Following breast cancer diagnosis, women often attempt to modify their lifestyles to improve their health and prevent recurrence. These behavioral changes typically involve diet and physical activity modification. The aim of this study was to determine association between healthy eating habits and physical activity with quality of life among Iranian breast cancer survivors. A total of 100 Iranian women, aged between 32 to 61 years were recruited to participate in this cross-sectional study. Eating practices were evaluated by a validated questionnaire modified from the Women's Healthy Eating and Living (WHEL) study. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). A standardized questionnaire by the European Organization of Research and Treatment of Cancer Quality of Life and its breast cancer module (EORTC QLQ-C30/+BR-23) were applied to determine quality of life. Approximately 29% of the cancer survivors were categorized as having healthy eating practices, 34% had moderate eating practices and 37% had poor eating practices based on nutrition guidelines. The study found positive changes in the decreased intake of fast foods (90%), red meat (70%) and increased intake of fruits (85%) and vegetables (78%). Generally, breast cancer survivors with healthy eating practices had better global quality of life, social, emotional, cognitive and role functions. Result showed that only 12 women (12%) met the criteria for regular vigorous exercise, 22% had regular moderate-intensity exercise while the majority (65%) had low-intensity physical activity. Breast cancer survivors with higher level of physical activity had better emotional and cognitive functions. Healthy eating practices and physical activity can improve quality of life of cancer survivors. Health care professionals should promote good dietary habits and physical activity to improve survivors' health and quality of life.

    In comparison to monolayer cells, MCTS has been claimed as more suitable candidate for studying drug penetration due to the high resemblance to solid tumors. However, the cultivation of MCTS is cumbersome, time consuming, and most technique fail to generate spheroids with uniform sizes. Therefore, the application of spheroid cultures in high throughput screening has been rather limiting. Besides, the lack of a well established screening protocol method that is applicable to spheroid could also be attributed to this limitation. Here we report a simple way of cultivating homogenous MCTS cultures with compact and rigid structure from the MCF-7 cells. Besides, we had also made some modifications to the standard MTT assay to realize high throughput screening of these spheroids. Using the modified protocol, tamoxifen showed cytotoxicity effect towards MCTS cultures from MCF-7 with high consistency. The results correlated well with the cultures' response assessed by LDH release assay but the latter assay was not ideal for detecting a wide range of cytotoxicity due to high basal background reading. The MTT assay emerged as a better indicator to apoptosis event in comparison to the LDH release assay. Therefore, the method for spheroid generation and the modified MTT assay we reported here could be potentially applied to high throughput screening for response of spheroid cultures generated from MCF-7 as well as other cancer cell lines towards cytotoxic stimuli.

    INTRODUCTION: Today, cancer survivors have an added new role to self manage living with the medical, emotional and role tasks that can affect their quality of life (QOL). The purpose of the study was to evaluate the QOL of women two years after participating in a self-management intervention program.

    METHOD: The clinical trial was conducted at University Malaya Medical Centre between 2006 and 2008. The experimental group underwent a 4-week self management program, and the control group underwent usual care. Two years after the intervention, questionnaires were randomly posted out to the participants.

    RESULTS: A total of 51 questionnaires returned. There were statistically differences between groups in psychological, self-care, mobility and participation aspects in PIPP (p<0.05). The experimental group reported having higher confidence to live with breast cancer compared to control group (p<0.05). There were significant between-group changes in anxiety scores at T2 (immediately after intervention) to T4 (two years later), and the differences in anxiety scores within groups between time point T2 and T4 were significantly different (p<0.05).

    CONCLUSION: The SAMA program is potentially capable to serve as a model intervention for successful transition to survivorship following breast cancer treatment. The program needs to be further tested for efficacy in a larger trial involving more diverse populations of women completing breast cancer treatment.

    BACKGROUND: Increasing survivorship warrants evidence-based intervention to help women manage living effectively with breast cancer. Breast cancer survivors may have many medical and psychosocial issues in the post- treatment period. Qualitative research was carried out to assess survivors' overall experience and if intervention helps in survivorship care. This paper reports exploration of benefit-findings from participation in an earlier 4-week self management intervention.

    METHODS: We used a grounded theory approach to analyze three focus groups conducted between May and August 2010 in Kuala Lumpur. We used random sampling to recruit the informants (n=21), all of whom had earlier participated in the 4 week self-management program held two years previously.

    FINDINGS: The women reported positive experience and growth with the self management program. Self-efficacy appears as an important underlying theme for successful experiences. The lack of proactive plans to provide bereavement support to surviving women was a key negative experience.

    CONCLUSION: The intervention successfully brought women together to work in close partnership with health professionals on ways to self manage the medical, emotional and role task as they live indefinitely with breast cancer, a new chronic illness. The beneficial effect from the 4 week intervention was expressed by women even at 2 years after the program. Having successfully developed a tightly knitted group, a major oversight was the lack of professional support on bereavement for grieving members when close friends passed away.

    BACKGROUND: Many cancer survivors are still not active enough to reap the benefits of physical activity. This study aimed to explore the correlation between perceived barriers and participation in exercise among multi- ethnic Malaysian women with breast cancer.

    METHODS: A cross-sectional study using a pre-post questionnaire and a media-clip as a cancer control strategy was conducted on a random sample of women with breast cancer. The tools were structured questionnaires to collect socio-medical demographic and physical activity data (e.g. barriers, exercise self-efficacy).

    RESULTS: A statistically significant relationship between level of physical activity before and after diagnosis of breast cancer (n=51, χ2=70.14, p<0.01) was found, whereby participants who rated more hours of physical activity before diagnosis were likely to persevere with exercise after diagnosis, r(49)=0.73, p<01. Some 76.5% of women engaged in low level activity and 23.5% of the participants engaged in moderate level of physical activity.

    CONCLUSIONS: Despite the many benefits of physical activity, the majority of survivors in this study were not found to be physically active, and did not even consciously think of exercise participation. Lack of time is the main barrier amongst those survivors who are predominantly 40-50 year old housewives juggling with household chores, childcare and/or job commitments. Public health messages stressing that short bouts of exercise or some exercise are better than no exercise needs to be emphasised consistently.

    This paper presents the results obtained for medical image compression using autoencoder neural networks. Since mammograms (medical images) are usually of big sizes, training of autoencoders becomes extremely tedious and difficult if the whole image is used for training. We show in this paper that the autoencoders can be trained successfully by using image patches instead of the whole image. The compression performances of different types of autoencoders are compared based on two parameters, namely mean square error and structural similarity index. It is found from the experimental results that the autoencoder which does not use Restricted Boltzmann Machine pre-training yields better results than those which use this pre-training method.

    To successfully initiate and maintain breastfeeding for a longer duration, the World Health Organization's Ten Steps to Successful Breastfeeding recommends total avoidance of artificial teats or pacifiers for breastfeeding infants. Offering the pacifier instead of the breast to calm the infant may lead to less frequent episodes of breastfeeding and as a consequence may reduce breast milk production and shorten duration of breastfeeding; however, this remains unclear.

    The performance of a digital mammography system (Siemens Mammomat Novation) using different target/filter combinations and tube voltage has been assessed. The objective of this study is to optimize beam quality selection based on contrast-to-noise ratio (CNR) and mean glandular dose (MGD). Three composition of breast were studied with composition of glandular/adipose of 30/70, 50/50, and 70/30. CNR was measured using 2, 4 and 6 cm-thick simulated breast phantoms with an aluminium sheet of 0.1 mm thickness placed on top of the phantom. Three target/filter combinations, namely molybdenum/molybdenum (Mo/Mo), molybdenum/rhodium (Mo/Rh) and tungsten/rhodium (W/Rh) with various tube voltage and mAs were tested. MGD was measured for each exposure. For 50/50 breast composition, Mo/Rh combination with tube voltage 26 kVp is optimal for 2 cm-thick breast. W/Rh combination with tube voltage 27 and 28 kVp are optimal for 4 and 6 cm-thick breast, respectively. For both 30/70 and 70/30 breast composition, W/Rh combination is optimal with tube voltage 25, 26 and 27 kVp, respectively. From our study it was shown that there are potential of dose reduction up to 11% for a set CNR of 3.0 by using beam quality other than that are determined by AEC selection. Under the constraint of lowest MGD, for a particular breast composition, calcification detection is optimized by using a softer X-ray beam for thin breast and harder X-ray beam for thick breast. These experimental results also indicate that for breast with high fibroglandular tissues (70/30), the use of higher beam quality does not always increase calcification detection due to additional structured noise caused by the fibroglandular tissues itself.

    This paper presents an approach for breast cancer diagnosis in digital mammogram using curvelet transform. After decomposing the mammogram images in curvelet basis, a special set of the biggest coefficients is extracted as feature vector. The Euclidean distance is then used to construct a supervised classifier. The experimental results gave a 98.59% classification accuracy rate, which indicate that curvelet transformation is a promising tool for analysis and classification of digital mammograms.

    Hybridoma clone C3A8, which is a fusion product between splenic lymphocytes of Balb/c mice immunized with MCF7 breast carcinoma cells and SP2/0 myelomas, was produced and characterized. A stable clone that secreted IgM monoclonal antibody (MAb) with kappa light chain was obtained through limiting dilutions. Cell-ELISA screening, flow cytometry analysis, and immunofluorescence staining revealed that the MAb C3A8 had bound specifically and strongly to MCF7 and HT29 but cross reacted weakly or not on HeLa cell line. The MAb C3A8 reacted positively with paraffin-embedded tissues of human breast and colon cancers but there were no positive reactions on normal tissues. Western blot analysis showed the MAb recognized a 55 kDa protein, which was present in the extract of MCF7 and HT29 cell lines. Our results demonstrated that MAb C3A8 could be used for basic and clinical research of breast and colon cancers.

    Breast cancer is the most common cancer and the leading cause of cancer death among women of all ethnic and age groups in Malaysia.

    OBJECTIVE: The objectives of this study were to evaluate the knowledge of breast cancer risk factors, symptoms and methods of screening among female university students and their perception towards the disease treatment outcomes.

    METHODS: A cross-sectional survey was conducted from February to March 2008 at Universiti Sains Malaysia. Two hundred participants from 10 randomly selected faculties were interviewed face to face by a trained pharmacist using a validated questionnaire. In addition to their demographic characteristics, participants were required to answer 22 questions concerning knowledge of breast cancer and five questions related to their perception of breast cancer management and treatment outcomes. Data were analyzed using SPSS version 15.

    RESULTS: The mean age of the respondents was 26.7 (SD=1.9) years. The results showed that the vast majority of the female university students had inadequate knowledge of breast cancer. The mean total knowledge score of the students was 60.7%. Indian students had significantly less knowledge of breast cancer compared to their Chinese and Malay counterparts (p<0.05). However, more than two third of the students were aware of breast self examination (BSE) and clinical breast examination (CBE) recommendations. Furthermore, the students had positive perceptions towards the treatment outcomes of breast cancer.

    CONCLUSION: This study has highlighted the need of a breast cancer awareness campaign, which should also stress the importance of early detection and reporting of breast cancer.

    BACKGROUND: Mastitis can be caused by ineffective positioning of the baby at the breast or restricted feeding. Infective mastitis is commonly caused by Staphylococcus Aureus. Incidence of mastitis in breastfeeding women may reach 33%. Effective milk removal, pain medication and antibiotic therapy have been the mainstays of treatment.

    OBJECTIVES: This review aims to examine the effectiveness of antibiotic therapies in relieving symptoms for breastfeeding women with mastitis with or without laboratory investigation.

    SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (December 2007), the Cochrane Central Register of Clinical Trials (The Cochrane Library 2007, Issue 4), MEDLINE (1996 to 2007) and EMBASE (January 1985 to 2007). We contacted investigators and other content experts known to us for unpublished trials and scanned the reference lists of retrieved articles

    SELECTION CRITERIA: Randomized and quasi-randomized clinical trials comparing the effectiveness of various types of antibiotic therapies or antibiotic therapy versus alternative therapies for the treatment of mastitis were selected.

    DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. When in dispute, we consulted a third author.

    MAIN RESULTS: Two trials met the inclusion criteria. One small trial (n = 25) compared amoxicillin with cephradine and found no significant difference between the two antibiotics in terms of symptom relief and abscess formation. Another, older study compared breast emptying alone as "supportive therapy" versus antibiotic therapy plus supportive therapy, and no therapy. The findings of the latter study suggested faster clearance of symptoms for women using antibiotics, although the study design was problematic.

    AUTHORS' CONCLUSIONS: There is insufficient evidence to confirm or refute the effectiveness of antibiotic therapy for the treatment of lactational mastitis. There is an urgent need to conduct high-quality, double-blinded randomized clinical trials to determine whether antibiotics should be used in this common postpartum condition.

    Autoantibodies to survivin have been reported in lung cancers and in gastrointestinal cancers. A few reports have also described a low prevalence of autoantibodies to survivin and at low titres in the sera of breast cancer patients with no implications for their clinical usefulness. This study was designed to re-examine the prevalence and the clinical correlations of autoantibodies to the tumour protein survivin, in the sera of patients with infiltrating ductal carcinoma of the breast using an ELISA assay. In spite of the low prevalence of autoantibodies to survivin (7%, n = 57), their presence was associated with grade III tumours, with tumour sizes exceeding 10cm, with axillary lymph nodal involvement and with metastases. Moreover, all the autoantibody-positive cases were estrogen and progesterone receptors negative. Furthermore, all the autoantibody-positive cases expressed survivin with high scores.

    OBJECTIVE: The aim of this study was to investigate if preemptive local infiltration (PLA) with ropivacaine could improve postoperative pain and determine its effect on drain output postmastectomy with axillary dissection.
    METHODS: This was a prospective, randomized trial comprising 30 women allocated to two groups: one to receive postoperative wound infiltration (POW) of 20 mL of 0.2% (40 mg) ropivacaine (Naropin) versus PLA with 20 mL of 0.2% ropivacaine (Naropin) diluted with 80 mL of 0.9% saline, total volume 100 mL. A visual analogue scale (0-100 mm) and angle of shoulder abduction were used for evaluation of pain. Postoperatively, all patients received oral ibuprofen 400 mg tds.
    RESULTS: There was no significant difference in postoperative pain for the first 3 days between the two groups. There were wider shoulder abduction angles in the 1st and 3rd postoperative days in the PLA group, but this was not significant. Operative time was significantly shorter in the PLA group than in the POW group (69.34+/-59.37 minutes vs. 109.67+/-26.96 minutes; p=0.02). The axillary drain was removed earlier in the preemptive group, 5.4+/-1.55 days versus 6.8+/-2.04 days in the postoperative group (p=0.04).
    CONCLUSION: We found no difference in postoperative pain between preemptive tumescent ropivacaine infiltration and postoperative ropivacaine wound infiltration.
