We report for the first time, to the best of our knowledge, regenerated polymer optical fiber Bragg gratings(RPOFBGs) in ZEONEX-based polymer optical fibers(POFs). The regeneration temperature can be adjusted using a heat treatment process on the POF before FBG inscription, enabling a scalable improvement of the thermal stability of the RPOFBGs. Thermal sustainability of the RPOFBGs at high temperature conditions was investigated for their prolonged use in diverse environments. Furthermore, these RPOFBGs can withstand strain levels up to 2.8% while maintaining a good linearity, even at temperature of 110℃. The RPOFBGs are capable of short-term operation at elevated temperatures of up to 132℃, which is the standard temperature for steam sterilization with at least a 4 min exposure period. The distinction in the morphologies of the two grades of ZEONEX(E48R and 480R, ZEON Corp.) used to fabricate the optical fiber together with the characteristics of UV irradiated and regenerated gratings is explained using micro-Raman spectroscopy. Collectively, these findings provide new heights for long-term operation of POF Bragg gratings(POFBGs) at elevated temperature environments and would be applicable to a wide range of disciplines.

AIM:To elucidate etiologic associations between Helicobacter pylori(H pylori),lifestyle,environmental factors and gastric cardiac adenocarcinoma(GCA)among men. METHODS:A hospital-based case-control study was conducted in Taiwan from 2000 to *** cases were newly confirmed as primary *** controls were selected matching with age,sex,and admission date to each *** were informedof potential risk factors with a structured question- naire by trained interviewers during hospitalization and provided a blood sample for the determination of H pylori *** ratio(OR)and 95%confidence interval(95%CI)were used to evaluate risk,and a multivariate conditional logistic regression model was performed. RESULTS:All participants recruited for this study were men,consisting of 41 cases and 205 *** of the univariate analysis showed that significant factors associated with the etiology of GCA included H pylori(OR =2.69,95%CI=1.30-5.53),cigarette smoking(OR= 2.28,95%CI=1.05-4.96),working or exercising after meals(OR=3.26,95%CI=1.31-8.11),salted food (OR=2.51,95%CI=1.08-6.11),fresh vegetables(OR =0.28,95%CI=0.09-0.80),fruits(OR=0.19,95% CI=0.04-0.89),and rice as principal food(OR=0.53, 95%CI=0.30-0.85).Multivariate conditional logistic regression models indicated that a significantly elevated risk of contracting GCA was associated with working or exercising after meals(OR=3.18,95%CI=1.23-9.36) and H pylori infection(OR=2.93,95%CI=1.42-6.01). In contrast,the consumption of fresh vegetables(OR =0.22,95%CI=0.06-0.83),fruits(OR=0.28,95% CI=0.09-0.79)and rice as principal food(OR=0.48, 95%CI=0.24-0.93)remained as significant beneficial factor associated with GCA. CONCLUSION:Working or exercising after meals and H pylori infection increase the risk of GCA,but higher intakes of rice,fresh vegetables and fruits reduce the risk.

AIM: To investigate the age differences in the risk factors, clinicopathological characteristics and patterns of treatment of female breast cancer patients. METHODS: Seven thousand one hundred and fiftytwo women with primary breast cancer from the Hong Kong Breast Cancer Registry were recruited after receiving patients' consent, they were asked to complete standardized questionnaires which captured their sociodemographic characteristics and risk factors associated with breast cancer development. Among them, clinicopathological data and patterns of treatment were further collected from medical records of 5523 patients with invasive breast cancers. Patients were divided into two groups according to the age at diagnosis: younger(< 40 years old) vs older patients(≥ 40 years old) for subsequent ***: Analysis on the sociodemographic characteristics and exposure to risk factors were performed on 7152 women with primary breast cancer and the results revealed that younger patients were more likely to have unhealthy lifestyles; these include a lack of exercise(85.4% vs 73.2%, P < 0.001), having high stress in life(46.1% vs 35.5%, P < 0.001), having dairy/meat-rich diets(20.2% vs 12.9%, P < 0.001),having alcohol drinking habit(7.7% vs 5.2%, P = 0.002). Younger patients were also more likely to have hormone-related risk factors including nulliparity(43.3% vs 17.8%, P < 0.001) and an early age at menarche(20.7% vs 13.2%, P < 0.001). Analyses on clinicopathological characteristics and patterns of treatment were performed on 5523 women diagnosed with invasive breast cancer. The invasive tumours in younger patients showed more aggressive pathological features such as having a higher percentage of grade 3 histology(45.7% vs 36.5%, P < 0.001), having a higher proportion of tumours with lymphovascular invasion(39.6% vs 33.2%, P = 0.003), and having multifocal disease(15.7% vs 10.3%, P < 0.001); they received different patterns of treatment than their older ***
