Abstract
Nanoencapsulation has appeared as an alternative approach to protect the bioactive constituents of essential oils (EOs) and to improve their properties. In this study, Cynometra cauliflora essential oils (CCEOs) were nanoencapsulated in chitosan nanoparticles (CSNPs) using an emulsion-ionic gelation technique. Transmission electron microscopy (TEM) images illustrated a well dispersion and spherical shape of C. cauliflora EOs-loaded chitosan nanoparticles (CCEOs-CSNPs) with an average size of less than 100 nm. In addition to that, Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS) and X-ray diffraction (XRD) analyses revealed the success of CCEOs nanoencapsulation. The encapsulation efficiency (EE) was in the range of 38.83% to 44.16% while the loading capacity (LC) reached 32.55% to 33.73%. The antioxidant activity (IC50) of CCEOs-CSNPs was ranged from 21.65 to 259.13 μg/mL when assessed using DPPH radical scavenging assay. CCEOs-CSNPs showed an appreciable antimicrobial effects on diabetic wound microorganisms. Notably, cytotoxic effects against human breast cancer MCF-7 and MDA-MB-231 cells recorded IC50 of 3.72-17.81 μg/mL and 16.24-17.65 μg/mL, respectively, after 72 h treatment. Interestingly, no cytotoxicity against human breast normal MCF-10A cells was observed. Thus, nanoencapsulation using CSNPs could improve the properties of CCEOs in biomedical related applications.

A Bottom-Up Synthesis Approach to Silver Nanoparticles Induces Anti-Proliferative and Apoptotic Activities Against MCF-7, MCF-7/TAMR-1 and MCF-10A Human Breast Cell Lines.

Abstract
A bottom-up approach for synthesizing silver nanoparticles (AgNPs-GA) phytomediated by Garcinia atroviridis leaf extract is described. Under optimized conditions, the AgNPs-GA were synthesized at a concentration of 0.1 M silver salt and 10% (w/v) leaf extract, 1:4 mixing ratio of reactants, pH 3, temperature 32 °C and 72 h reaction time. The AgNPs-GA were characterized by various analytical techniques and their size was determined to be 5–30 nm. FTIR spectroscopy indicates the role of phenolic functional groups in the reduction of silver ions into AgNPs-GA and in supporting their subsequent stability. The UV-Visible spectrum showed an absorption peak at 450 nm which reflects the surface plasmon resonance (SPR) of AgNPs-GA and further supports the stability of these biosynthesized nanoparticles. SEM, TEM and XRD diffractogram analyses indicate that AgNPs-GA were spherical and face-centered-cubic in shape. This study also describes the efficacy of biosynthesized AgNPs-GA as anti-proliferative agent against human breast cancer cell lines, MCF-7 and MCF-7/TAMR-1. Our findings indicate that AgNPs-GA possess significant anti-proliferative effects against both the MCF-7 and MCF-7/TAMR-1 cell lines, with inhibitory concentration at 50% (IC50 values) of 2.0 and 34.0 µg/mL, respectively, after 72 h of treatment. An induction of apoptosis was evidenced by flow cytometry using Annexin V-FITC and propidium iodide staining. Therefore, AgNPs-GA exhibited its anti-proliferative activity via apoptosis on MCF-7 and MCF-7/TAMR-1 breast cancer cells in vitro. Taken together, the leaf extract from Garcinia atroviridis was found to be highly capable of producing AgNPs-GA with favourable physicochemical and biological properties.

Patient-Reported Outcome Measures Among Breast Cancer Survivors in Malaysia: A Comparative Study With Patients From High-Income Countries. J Glob Oncol 2018.

Abstract
Background: Patient-reported outcome measures (PROMs) are essential for identifying how patients perceive the outcomes of their cancer treatment, and is the ultimate success of cancer care. Although a growing number of studies have focused on PROMs in high income countries (HICs), outcomes relevant to patients in developing countries are less understood. Furthermore, the lack of standardization in PROMs makes it difficult to interpret these data for research or quality monitoring. Aim: In this study, we compared the results of PROM measures between patients in Malaysia, a middle income country, and those in HICs, using standard PROMs questionnaires. We also explored the differences in perceived importance of patient reported outcomes within the multiracial Malaysian cohort. Methods: Breast cancer patients (n=1063) were recruited in hospitals serving suburban areas of Malaysia. Of these, 969 patients were eligible for analysis. The surveys were conducted through face-to-face interviews (68%) or were self-administered (30%). An outcome was considered important if it was scored between 7-9 on a 9-point Likert scale. We compared PROMs scores between Malaysian patients and data previously collected from patients in HICs using logistic regression models, adjusting for demographic and clinical characteristics. A two-step cluster analysis was conducted to explore differences in the perceived importance of PROMs between clusters of Malaysian patients. Results: Compared with 1777 patients from HICs, Malaysian patients were less likely to rate overall and recurrence free survival, as well as emotional, cognitive, social and sexual functioning as very important outcomes. Interestingly, more Malaysian women reported that pain (50% vs. 39%), breast symptoms (51% vs. 35%), and major complications (60% vs. 44%) were very important outcomes ( P < 0.001). Compared with young, married Malaysian women, the cluster of older married women (mean age of 57 vs. 52), who were less likely to have received breast reconstructive surgery (8.6% vs. 16.8%), was more likely to rate sexual functioning (32.8% vs. 25.0%, P = 0.036), body image (63.9% vs. 42.4%, P < 0.001), and satisfaction with the breast (50.7% vs. 37.0%, P = 0.011) as very important outcomes. Conclusion: The differences in breast cancer patient needs between and within populations should be considered carefully to better clinician-patient relationship, patient care and satisfaction and assess the outcomes of our cancer care. Future research is needed to find suitable targeted interventions to identify and address the diverse needs of breast cancer patients in low and middle income countries.
