Weight Gain and its Correlates among Breast Cancer Survivors

Purpose: Weight gain after diagnosis of breast cancer is a profound issue that may negatively impact cancer prognosis. However, most existing research on weight change has been conducted in Western countries. In addition, several factors related to weight gain have been reported; however, the evidence is inconsistent. The purpose of this study was to examine weight gain and its correlates among Korean breast cancer survivors. Methods: A total of 132 female breast cancer survivors were recruited from one university hospital in South Korea. Participants completed anthropometric measurements (i.e., body weight, height) and a selfreported questionnaire, including the International Physical Activity Questionnaire Short Form and Mini Dietary Assessment. Results: The mean weight change was -0.09 kg (SD = 4.28). Only 27 women (19.7%) gained more than 5% of their weight at diagnosis, 59.1% maintained weight, and 21.2% lost weight. In multivariate logistic regression analysis, significant correlates of weight gain were younger age, obesity at diagnosis, duration of more than 36 months since diagnosis, and low diet quality. Conclusion: Younger women, women who were obese at diagnosis, women with more than 36 months since diagnosis, or women who showed lower diet quality should be considered at high-risk for weight gain. Findings from our study suggest that optimal weight management strategies should be developed using ethnically- or culturally-appropriate approaches.

Background: Diabetic foot ulcer is one of the most important complications of diabetes mellitus as the leading cause of lower limb amputation. Because of its high complexity of management, a variety of clinical trials has bean studied. PRP(Platelet-Rich Plasma) is blood plasma that has been enriched with more than a million platelets per ㎣. As a concentrated source of autologous platelets, PRP contains a large numbers of different types of growth factors and cytokines that stimulate wound healing. Red light-emitting diode (LED) therapy (633 nm) also used, which is known that accelerates wound healing and skin rejuvenation. Objectives: In this study, there are 5 cases of diabetic foot ulcer which were treated with the combination therapy with PRP and LED light. Methods: We selected the patients who have superficial ulcer without inflammation or necrosis of periwound. Two or three times of PRP and more than four times of LED lightening were applied to patients depending on their individual wound status. The mean period of the treatment was about 2 months. Results: All of the cases showed successful healing of ulcer with reepithelization and decrease of size. Conclusion: The results of this study show that the combination therapy with PRP and LED light is effective and safe for use in the treatment of diabetic foot ulcers.

Light trapping is a key issue in improving the efficiency of thin-film Si solar cells, and using a back reflector material plays a critical role in improving a cell’s light-trapping efficiency. In this study, we developed n-type microcrystalline silicon oxide (n-mc-SiOx) films that are suitable for use as back reflectors in thin-film silicon solar cells. They exhibit a lower refractive index and lower absorption spectra, especially at long wavelengths of >700 nm, than conventional ZnO:Al materials, which are beneficial for this application. The n-mc-SiOx films were prepared by the PECVD (plasma-enhanced chemical vapor deposition) method and applied to the fabrication of back reflectors in mc-Si:H solar cells. We also characterized the changes in cell performance with respect to the refractive index, conductivity,and thickness of the n-mc-SiOx back reflectors. The novel back reflector boosts the total current density by up to 3.0% with the help of the enhanced long-wavelength response. It also improves open circuit voltage (Voc) and fill factor (FF), which may be attributed to the reduced shunt current caused by the anisotropic electrical characteristics of the n-mc-SiOx layer. Finally, we could achieve a conversion efficiency for the hydrogenated microcrystalline silicon (mc-Si:H) solar cells of up to 9.3% (Voc: 0.501 V, Jsc: 27.4 mA/cm2, FF:0.68) using the n-mc-SiOx back reflector.
