Abstract
BACKGROUND The CURB-65 score was designed to predict 30-day mortality and decide the site of care of pneumonia. It is uncertain how age and residential status affect the accuracy of CURB-65 score in older patients. AIM This study aimed to evaluate the effect of age and residential status on the performance of CURB-65 score in predicting 30-day all-cause mortality of pneumonia in older patients. METHODS We used combined data from two prospective observational cohorts of adult patients with pneumonia. Older patients aged ≥ 65 years were analysed. RESULTS Of 1644 patients, 1200 were living in the community and 464 residing in nursing homes. The 30-day mortality rates of community-acquired pneumonia (CAP) and nursing home-acquired pneumonia (NHAP) were 10.7% and 14.2% respectively. In each age group of CAP and NHAP, mortality increased with pneumonia severity. Mortality decreased with advancing age in NHAP, and the reverse was true for CAP. In NHAP but not CAP, the proportion of highly severe pneumonia (CURB-65 score ≥ 3) was lower in older patients. The overall predictive performance of CURB-65 score was comparable in CAP and NHAP. The accuracy deteriorated with advancing age in NHAP but not CAP. Using the cut-off score of ≥3 (highly severe pneumonia), the CURB-65 score achieved high negative predictive values (>90%) in CAP and NHAP. CONCLUSIONS Advancing age adversely affected the predictive performance of CURB-65 score in NHAP but not CAP. The score was not helpful in guiding the site of care at admission in older patients with pneumonia.

Abstract
Body mass index (BMI) and mortality in old adults from the general population have been related in a U-shaped or J-shaped curve. However, limited information is available for elderly nursing home populations, particularly about specific cause of death. A systematic PubMed/EMBASE/CINAHL/SCOPUS search until 31 May 2014 without language restrictions was conducted. As no published study reported mortality in standard BMI groups (<18.5, 18.5-24.9, 25-29.9, ≥30 kg/m(2)), the most adjusted hazard ratios (HRs) according to a pre-defined list of covariates were obtained from authors and pooled by random-effect model across each BMI category. Out of 342 hits, 20 studies including 19,538 older nursing home residents with 5,223 deaths during a median of 2 years of follow-up were meta-analysed. Compared with normal weight, all-cause mortality HRs were 1.41 (95% CI = 1.26-1.58) for underweight, 0.85 (95% CI = 0.73-0.99) for overweight and 0.74 (95% CI = 0.57-0.96) for obesity. Underweight was a risk factor for higher mortality caused by infections (HR = 1.65 [95% CI = 1.13-2.40]). RR results corroborated primary HR results, with additionally lower infection-related mortality in overweight and obese than in normal-weight individuals. Like in the general population, underweight is a risk factor for mortality in old nursing home residents. However, uniquely, not only overweight but also obesity is protective, which has relevant nutritional goal implications in this population/setting.

Abstract
BACKGROUND/OBJECTIVES Although observational studies suggest that soy foods or isoflavones are cardio-protective, clinical trials on whole soy or isoflavone daidzein (one major isoflavone and the precursor of equol) on blood pressure (BP) and endothelial function (EF) are few and have not been specifically conducted among equol producers, a population most likely to benefit from soy treatment. SUBJECTS/METHODS We performed a 6-month double-blind, randomized, placebo-controlled trial to examine the effect of whole soy (soy flour) or purified daidzein on BP and EF in prehypertensive or untreated hypertensive postmenopausal women verified to be equol producers. A total of 270 eligible women were recruited and randomized to either one of the three treatment groups, 40 g soy flour (whole soy group), 40 g low-fat milk powder+63 mg daidzein (daidzein group) or 40 g low-fat milk powder (active control group) daily, each given as a solid beverage powder for 6 months. The primary outcome measures were 24 h ambulatory BP (ABP) and EF assessed by flow-mediated dilation using brachial artery ultrasound. RESULTS A total of 253 subjects completed the study according to protocol. Urinary isoflavones indicated good compliance with the interventions. Intention to treat and per-protocol analysis indicated that there was no significant difference in the 6-month changes or % changes in parameters of ABP and brachial flow-mediated dilation among the three treatment groups. A further subgroup analysis among hypertensive women (n=138) did not alter the conclusions. CONCLUSIONS Whole soy and purified daidzein had no significant effect on BP and vascular function among equol-producing postmenopausal women with prehypertension or untreated hypertension.

Abstract
BACKGROUND Patients with non-alcoholic steatohepatitis (NASH) have increased intestinal permeability and small intestine bacterial overgrowth. AIMS To test the hypothesis that endotoxemia is associated with non-alcoholic fatty liver disease (NAFLD) in the general population, and to study dietary factors associated with endotoxemia. METHODS Nine hundred and twenty adults were randomly selected from the government's census database and underwent proton-magnetic resonance spectroscopy to assess hepatic steatosis. Endotoxemia was assessed using the limulus amebocyte lysate, lipopolysaccharide-binding protein (LBP) and EndoCab immunoglobulin G (IgG) assays. RESULTS Two hundred and sixty-three (29%) subjects had NAFLD. Subjects with NAFLD had slightly higher LBP (P < 0.001) and EndoCab IgG (P = 0.013) levels. EndoCab IgG remained an independent factor associated with intrahepatic triglycerides after adjusting for other metabolic factors. Among 565 subjects without NAFLD at baseline who had repeated assessment at a median interval of 47 months, 78 (13.8%) developed incident NAFLD and they also had higher LBP (P = 0.016). Moreover, LBP was associated with insulin resistance and dyslipidaemia, and modestly increased with the cytokeratin-18 fragment level but not liver stiffness measurement by transient elastography. Although total energy consumption and individual macronutrients were not associated with endotoxemia, current drinkers (mostly <140 g/week) had lower endotoxin, EndoCab IgG and fetuin-A levels than nondrinkers. CONCLUSIONS Endotoxin markers are associated with NAFLD in the general population, but do not have a major effect on NASH and fibrosis. People with modest alcohol consumption have lower serum endotoxin. This may partly explain the lower risk of NAFLD and NASH in modest drinkers in previous observational studies.

Abstract
Most present-day galaxies with stellar masses ≥10(11) solar masses show no ongoing star formation and are dense spheroids. Ten billion years ago, similarly massive galaxies were typically forming stars at rates of hundreds solar masses per year. It is debated how star formation ceased, on which time scales, and how this "quenching" relates to the emergence of dense spheroids. We measured stellar mass and star-formation rate surface density distributions in star-forming galaxies at redshift 2.2 with ~1-kiloparsec resolution. We find that, in the most massive galaxies, star formation is quenched from the inside out, on time scales less than 1 billion years in the inner regions, up to a few billion years in the outer disks. These galaxies sustain high star-formation activity at large radii, while hosting fully grown and already quenched bulges in their cores.

Abstract
PURPOSE OF REVIEW There is an increasing number of reports suggesting that indicators of obesity for the general adult population may need to be modified; that the magnitude of risk is attenuated or that adiposity may even be protective; and that additional adverse outcomes specific to older persons need to be considered. Finally, there are benefits and adverse effects of weight loss programmes for older persons. This article reviews publications addressing these issues from 2013 to March 2014. RECENT FINDINGS BMI was not considered to be as good an indicator of obesity because of loss of muscle mass with age. Higher body weight seems to be protective among older persons with chronic diseases or geriatric syndromes. Increased adiposity together with decreased muscle mass (sarcopenic obesity) is associated with adverse outcomes, although there is no consensus regarding the definition. Intentional weight loss has health benefits but is accompanied by muscle and bone loss, and therefore programmes should include components to counteract these changes. SUMMARY The magnitude of health risk associated with obesity is attenuated with age, and mild increase in adiposity may be beneficial for those who are frail and/or with chronic diseases. Weight loss programmes should include resistance exercises to counteract muscle loss.

Abstract
The study of rare human syndromes characterized by radiosensitivity has been instrumental in identifying novel proteins and pathways involved in DNA damage responses to ionizing radiation. In the present study, a mutation in mitochondrial poly-A-polymerase (MTPAP), not previously recognized for its role in the DNA damage response, was identified by exome sequencing and subsequently associated with cellular radiosensitivity. Cell lines derived from two patients with the homozygous MTPAP missense mutation were radiosensitive, and this radiosensitivity could be abrogated by transfection of wild-type mtPAP cDNA into mtPAP-deficient cell lines. Further analysis of the cellular phenotype revealed delayed DNA repair, increased levels of DNA double-strand breaks, increased reactive oxygen species (ROS), and increased cell death after irradiation (IR). Pre-IR treatment of cells with the potent anti-oxidants, α-lipoic acid and n-acetylcysteine, was sufficient to abrogate the DNA repair and clonogenic survival defects. Our results firmly establish that mutation of the MTPAP gene results in a cellular phenotype of increased DNA damage, reduced repair kinetics, increased cell death by apoptosis, and reduced clonogenic survival after exposure to ionizing radiation, suggesting a pathogenesis that involves the disruption of ROS homeostasis.

Abstract
BACKGROUND The rs738409 GG variant in patatin-like phospholipase 3 (PNPLA3) is associated with non-alcoholic fatty liver disease (NAFLD) and disease severity. However, it remains unclear if it contributes to the development of NAFLD through affecting dietary pattern. AIM To examine the association among PNPLA3 gene polymorphism, dietary pattern, metabolic factors and NAFLD. METHODS Liver fat and fibrosis were assessed by proton-magnetic resonance spectroscopy and transient elastography in 920 subjects from a population screening project (251 had NAFLD). Dietary nutrient intake was recorded using a locally validated food-frequency questionnaire. RESULTS The prevalence of GG genotype in NAFLD subjects was 20.7%, compared to 10.6% in controls (P < 0.001). Macronutrient intake was similar among subjects with different PNPLA3 genotypes. The presence of G allele was a predictor of NAFLD independent of nutrient intake and other metabolic factors (adjusted odds ratio to CC: CG, 2.00; GG, 2.68). In subjects without metabolic syndrome, G allele was even more closely correlated with NAFLD diagnosis (adjusted odds ratio to CC: CG, 2.22; GG, 3.39). The prevalence of NAFLD was only 12% in subjects with CC genotype and no metabolic syndrome, and increased to 34% in those with GG genotype and no metabolic syndrome. While NAFLD subjects had significantly lower fibre intake, there was no significant interaction between PNPLA3 and dietary pattern. CONCLUSIONS The G allele in PNPLA3 rs738409 increases the risk of NAFLD in the general population, especially in subjects without metabolic syndrome, independent of dietary pattern and metabolic factors.

Abstract
BACKGROUND Frailty in older Chinese has been less often studied and the selection of one screening test feasible in primary care and population survey is needed. We attempted to examine the sensitivity and specificity of each of the five Fried's criteria as a single screening test in the identification of frailty. METHODS We recruited 4000 community-dwelling Chinese adults 65 years or older stratified by 3 age-stratum and identified frailty as having 3 or more of Fried's criteria: underweight(BMI<18.5), handgrip strength( RESULTS The proportion of frailty in the 3 age groups (65-69 years, 70-74 years, 75 years and above) were 2.3%, 3.4% and 11.9% respectively in men and 1.4%, 2.6% and 11.6% in women. Among the 5 criteria, walking speed, grip strength and physical activity (PASE score) divided at their respective lowest quintile values, achieved similar Area Under Curve in the Receiver Operating Characteristics analysis. For walking speed, the sensitivity and specificity were 82.7% and 83.1% in men and 91.9% and 84.5% in women respectively. For grip strength, the corresponding values were 89.5% and 80.6% in men; and 84.5% and 81.9% in women. For physical activity, they were 83.7% and 83.5% in men; and 82.8% and 84.7% in women. CONCLUSION Either walking speed or grip strength measurement may be suitable for frailty screening in primary care or population health survey. A cut-off value of 0.9 m/s in walking speed and 28 kg in grip strength for older men; and a corresponding value of 0.8 m/s and 18 kg for older women is recommended for the screening of frailty in community-dwelling older Chinese adults.

Abstract
OBJECTIVE To examine the association of dietary protein intake with 4-year change in physical performance measures and muscle mass in Chinese community-dwelling older people aged 65 and older in Hong Kong. DESIGN Prospective cohort study design. SETTING Hong Kong, People's of Republic of China. PARTICIPANTS There were 2,726 (1411 male, 1315 female) community-dwelling older people aged 65 and older. MEASUREMENTS Baseline total, animal and vegetable protein intakes were collected using a validated food frequency questionnaire. Relative protein intake expressed as g/kg body weight was calculated and divided into quartiles for data analysis. Baseline and 4-year physical performance measures (normal and narrow 6-meters walking speed and step length in a 6-meters walk) were measured and 4-year change in appendicular skeletal muscle mass (ASM) from baseline was assessed by dual-energy X-ray absorptiometry. Univariate analysis identified age and sex as significant factors associated with change in physical performance measures or ASM, thus adjustments for these factors were made for subsequent analysis of covariance. RESULTS Median relative total protein intake was 1.3 g/kg body weight in men and 1.1 g/kg body weight in women. After adjustment for age and sex, relative total protein intake and animal protein intake were not associated with change in physical performance measures and ASM. In contrast, participants in the highest quartile (>0.72 g/kg body weight) of relative vegetable protein intake lost significantly less ASM over 4-year than those in the lowest quartile of relative vegetable protein intake (<=0.40 g/kg body weight) (adjusted mean ± SE: 0.270 ± 0.029 vs. 0.349 ± 0.030 kg, ptrend=0.025). There was no association between relative vegetable protein intake and change in physical performance measures. CONCLUSIONS Higher protein intake from vegetable source was associated with reduced muscle loss in Chinese community-dwelling older people in Hong Kong whereas no association between total and animal protein intake and subsequent decline in muscle mass or physical performance measures was observed in this sample.

Abstract
Abstract
Introduction: Breast cancer is a heterogeneous diseases, which is based on expression of the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Using these factors, molecular subtype can be determined as luminal A, luminal B, HER2+, and TNBC. This is considered as an important prognostic factor. In breast cancer, age is the one of the important prognostic factors and prognosis is varied according to patients’ age. We performed this study to analyze the impact of molecular subtypes on prognosis of breast cancer according to patients’ age.
Patients and methods: We performed this study by using Korean Breast Cancer Society Registration Program data. Total 15,286 patients are included into this study, and they underwent surgery during the period Jan. 2001 to Dec. 2006. All patients were divided into two groups according to age (younger: age≤34, older: age≥35) and molecular subtypes were classified into four groups as follows: luminal A (ER+ and/or PR+, HER2-), luminal B (ER+ and/or PR+ HER2+), HER2+ (ER-, PR-, HER2+), and triple-negative (ER-, PR-, HER2-). We determined prognostic impact of molecular subtype on overall survivals (OS). Clinicopathologic results and OS were compared by chi-square test, Kaplan Meier test, and Cox's hazards model.
Results: Younger group more frequently had tumors with negative hormone receptor (ER-/PR-), worse prognostic factors and diagnosed with more advanced stage compared to older group. In univariate analysis, molecular subtype was not related with OS in younger group (p = 0.069), but not in older group (p<0.001). In multivariate analysis, molecular subtype was an independent prognostic factor for OS only in older group (p = 0.690 vs p<0.001).
Conclusion: In young breast cancer patients, less than 35 years, the impact of molecular subtypes on overall survival was not significant compared to other age group.

Abstract
AIM Better understanding the impact of changes in physical activity levels on cardiorespiratory fitness, as measured by maximal oxygen uptake (VO(2max)) may inform preventive interventions. We aimed to determine longitudinal changes in physical activity levels over 5 years and the relationship between these changes with VO(2max) in a sample of Chinese midlife women. METHODS A total of 184 Chinese women aged 50-64 years in Hong Kong were enrolled for this study. Physical activity was assessed with the modified Chinese Baecke questionnaire at baseline (2002-2004) and follow-up (2008-2009). VO(2max) was measured with a symptom-limited maximal exercise test on an electrically braked cycle ergometer at follow-up. RESULTS Compared with subjects who were persistently inactive, those who were increasingly/persistently active had significantly higher levels of VO(2max) (P<0.05). Being persistently active was also independently associated with a high level of VO(2max) (OR: 4.4, 95%CI: 1.0-19.2). However, the rate of decline in VO(2max) with age was apparently greater in persistently active subjects compared with their persistently inactive peers, but the differences were not statistically significant. CONCLUSION Our findings suggest that maintaining a high level of physical activity may lead to higher levels of VO(2max).

Abstract
BACKGROUND Dietary patterns can be identified using a priori and a posterior approaches. Few studies have related dietary patterns with cognitive impairment in Chinese population. This study examined the risk of cognitive impairment associated with dietary patterns identified by both approaches. METHODS Baseline data on 1,926 Chinese men and 1,744 Chinese women aged > 65 years participating in a cohort study examining the risk factors for osteoporosis in Hong Kong were analyzed. Dietary data were collected using a validated food frequency questionnaire. Adherence to a priori dietary patterns, namely the Mediterranean Diet Score (MDS) was assessed. Factor analysis (FA) identified three a posterior dietary patterns: "vegetables-fruits" pattern which was rich in vegetables, fruits, soy products and legumes, "snacks-drinks-milk products" pattern which was a mixture of healthy and unhealthy food groups including fast food, sweets and desserts, nuts, milk products and whole grains, and "meat-fish" pattern which included frequent intake of meat, fish and seafood. Cognitive function was assessed by the Community Screening Instrument for Dementia (CSI-D). Multivariate logistic regression examined the risk of cognitive impairment with adjustment for potential confounders. RESULTS A total of 221 men and 656 women was classified as cognitive impaired. Neither the MDS nor the dietary patterns identified by FA were associated with risk of cognitive impairment in men. In women, higher "vegetables-fruits" pattern score was associated with reduced risk of cognitive impairment [Adjusted OR=0.73 (95% CI: 0.54-1.00) of the highest quartile of "vegetables-fruits" pattern score compared with the lowest quartile, ptrend=0.018]. Similar inverse trend was observed for "snacks-drinks-milk products" pattern score [Adjusted OR=0.65 (95% CI: 0.47-0.90) of the highest quartile of "snacks-drinks-milk products" pattern score compared with the lowest quartile, ptrend=0.003]. There was no association of "meat-fish" pattern or the MDS with risk of cognitive impairment in women. CONCLUSION Higher "vegetables-fruits" and "snacks-drinks-milk products" pattern scores were associated with reduced risk of cognitive impairment in Chinese older women in Hong Kong.

Abstract
OBJECTIVES This study examines the recent trends in ischaemic heart disease (IHD) incidence and case fatality in Hong Kong and explores the possible risk factors. DESIGN Retrospective observational study. SETTING All public hospitals in Hong Kong. OUTCOME MEASURES Incidence rate was defined as the number of IHD inpatient episodes divided by the size of the corresponding population. Short-term and long-term case fatality rate was defined as deaths from all causes occurring within 30 and 31-365 days, respectively, divided by the number of IHD inpatient episodes among the corresponding population. METHODS Poisson and logistic regression models were used to examine the IHD incidence and short-term/long-term case fatality trends, respectively, for different age and sex groups. RESULTS IHD incidence was stable in most age groups. However, the incidence in men aged 15-24, 35-44 and ≥85 years showed increasing trends, whereas the incidence in men aged 55-64 years and women aged 35-74 years showed decreasing trends. Overall, the short-term/long-term case fatality rates were unchanged over time for both sexes. Short-term case fatality showed increasing trends in women aged 65-74 and ≥85 years, while long-term case fatality in men aged 55-64 and 75-84 years and women aged ≥75 years showed increasing trends. CONCLUSIONS Hong Kong trends resembled those in the USA, England and Wales, showing stable or slow decline in the IHD rates, while increasing trends were observed for some age groups, particularly young adults. Public health promotion efforts should focus on reducing cardiovascular risk factors, such as hypertension prevalence.

Abstract
AIMS/HYPOTHESIS Most genetic variants identified for type 2 diabetes have been discovered in European populations. We performed genome-wide association studies (GWAS) in a Chinese population with the aim of identifying novel variants for type 2 diabetes in Asians. METHODS We performed a meta-analysis of three GWAS comprising 684 patients with type 2 diabetes and 955 controls of Southern Han Chinese descent. We followed up the top signals in two independent Southern Han Chinese cohorts (totalling 10,383 cases and 6,974 controls), and performed in silico replication in multiple populations. RESULTS We identified CDKN2A/B and four novel type 2 diabetes association signals with p < 1 × 10(-5) from the meta-analysis. Thirteen variants within these four loci were followed up in two independent Chinese cohorts, and rs10229583 at 7q32 was found to be associated with type 2 diabetes in a combined analysis of 11,067 cases and 7,929 controls (p meta = 2.6 × 10(-8); OR [95% CI] 1.18 [1.11, 1.25]). In silico replication revealed consistent associations across multiethnic groups, including five East Asian populations (p meta = 2.3 × 10(-10)) and a population of European descent (p = 8.6 × 10(-3)). The rs10229583 risk variant was associated with elevated fasting plasma glucose, impaired beta cell function in controls, and an earlier age at diagnosis for the cases. The novel variant lies within an islet-selective cluster of open regulatory elements. There was significant heterogeneity of effect between Han Chinese and individuals of European descent, Malaysians and Indians. CONCLUSIONS/INTERPRETATION Our study identifies rs10229583 near PAX4 as a novel locus for type 2 diabetes in Chinese and other populations and provides new insights into the pathogenesis of type 2 diabetes.

Abstract
The objective of this study was to examine the inhibitory effect of probiotic strains on pathogenic biofilm formation in terms of competition, exclusion and displacement. Probiotic strains (Lactobacillus acidophilus KACC 12419, Lact. casei KACC 12413, Lact. paracasei KACC 12427 and Lact. rhamnosus KACC 11953) and pathogens (Salmonella Typhimurium KCCM 40253 and Listeria monocytogenes KACC 12671) were used to evaluate the auto-aggregation, hydrophobicity and biofilm formation inhibition. The highest auto-aggregation abilities were observed in Lact. rhamnosus (17·5%), Lact. casei (17·2%) and Lact. acidophilus (15·1%). Salm. Typhimurium had the highest affinity to xylene, showing the hydrophobicity of 53·7%. The numbers of L. monocytogenes biofilm cells during the competition, exclusion and displacement assays were effectively reduced by more than 3 log when co-cultured with Lact. paracasei and Lact. rhamnosus. The results suggest that probiotic strains can be used as alternative way to effectively reduce the biofilm formation in pathogenic bacteria through competition, exclusion and displacement.

Abstract
BACKGROUND Dietary patterns can be identified by a priori and a posterior approaches. Limited data have related dietary patterns with stroke risk in Chinese population. This study examined stroke risk associated with patterns identified by both approaches. METHODS Data on 1,338 Chinese men and 1,397 Chinese women aged >= 65 years participating in a cohort study examining the risk factors for osteoporosis in Hong Kong were analyzed. Baseline dietary data were collected between 2001 and 2003 using a validated food frequency questionnaire. Adherence to a priori dietary patterns including the Mediterranean Diet Score (MDS) and the Dietary Approaches to Stop Hypertension (DASH) was assessed. Factor analysis (FA) identified three a posterior dietary patterns: "vegetables-fruits", "snacks-drinks-milk products", and "meat-fish". Data on incidence of stroke were retrieved from an official database in 2008. Cox regression was used to estimate hazard ratios (HRs) for stroke risk adjusted for potential confounders. RESULTS There were 156 incident stroke events during a median follow up of 5.7 years. A posterior dietary patterns derived by FA were not associated with risk of incident stroke in either men or women. MDS was inversely associated with risk of incident stroke [Adjusted HR=0.55 (95% CI: 0.31-0.99) of the highest level of MDS compared with the lowest level, ptrend=0.008] in men but not in women. Similar non-significant inverse association was observed between DASH accordance and stroke risk in men [Multivariate HR (95% CI) of the DASH score of >=4.5 = 0.62 (0.38-1.04) compared with the DASH score of <=4, ptrend = 0.068] but not in women. CONCLUSION Our findings suggest that higher MDS and possibly higher DASH scores were associated with lower stroke risk in Chinese older people in Hong Kong.

Abstract
AIM Myokines and angiogenesis factors, studies on trainings according to the difference of exercise intensity are not sufficient, and it has not been elucidated. Particularly, studies on the effect of resistance exercise according to the intensity of resistance exercise on blood myokines and angiogenesis may be essential in the metabolic process of angiogenesis and the formation of muscle. METHODS The subjects of our studies were healthy male college students (N.=30) randomly assigned to the high intensity exercise group (N.=10), the moderate intensity exercise group (N.=10), and the control group (N.=10). The study was performed after obtaining a consent in advance, and the approval from the Institutional Review Board of Dong-A University Hospital. In the body composition test, height, weight, BMI (body mass index), %fat, and LBM (lean body mass) were measured by electric impedance. In blood analysis, myokines (interleukin (IL)-6, IL-8, IL-15) and angiogenesis factors (vascular endothelial growth factor (VEGF), angiopoietin (Ang)1, follistatin (FLRG)) were analyzed by ELISA methods. RESULTS The results show %body fat and LBM of the three groups were significantly different (P<0.05). IL-6 and IL-8 of the three groups were significantly different (P<0.05). Particularly, IL-8 of RE60 (60% of 1RM) was shown to be significantly higher than other groups (P<0.05). IL-15 also showed significant differences with time (P<0.05). In addition, VEGF and Ang 1 showed significant differences with time (P<0.05), nonetheless, FLRG did not showed statistical differences. CONCLUSION Many of muscle contraction through 8 weeks resistance exercise exerted positive effects on the concentration of blood myokines as well as angiogenesis. Particularly, in regard to blood myokines, moderate intensity exercise were more effective than high intensity exercise, which is considered to be due to that continuous muscle contraction of moderate intensity exercises exerted more positive effects on the elevation of the concentration of myokines than less muscle contraction of high intensity exercise.

Abstract
AIM To characterize the cellular and molecular properties of Salmonella Typhimurium exposed to antimicrobials in association with physicochemical property, biofilm formation ability and gene expression patterns. METHODS AND RESULTS The antimicrobial susceptibilities against Salmonella Typhimurium were evaluated to determine the MICs of allyl isothiocyanate (AITC), thymol, eugenol and polyphenol. Cell surface hydrophobicity, aggregation and biofilm formation assays were conducted to assess the physicochemical properties of Salm. Typhimurium treated with sublethal concentrations (SLC(2D) ) of antimicrobials. The expression patterns of adhesion-related genes (adrA, csgD, fimA and lpfE), virulence-related genes (hilA and stn) and efflux-related genes (acrA, acrB, ompD and tolC) were evaluated by real-time RT-PCR. Thymol exhibited the highest antimicrobial activity against Salm. Typhimurium planktonic, biofilm and dispersed cells, showing 0·18, 0·96 and 0·42 mg ml(-1) of SLC(2D) values, respectively. The antimicrobial-treated Salm. Typhimurium showed low hydrophobicity. The highest auto-aggregation ability (67%) of polyphenol-treated Salm. Typhimurium was positively associated with the enhanced ability to form biofilms. The csgD, fimA, hilA and lpfE genes were up-regulated in the polyphenol-treated Salm. Typhimurium planktonic and biofilm cells. CONCLUSION The results suggest that the antimicrobial resistance and virulence potential varied depending on the physiological states of Salm. Typhimurium during the transition from planktonic to biofilm cell growth. SIGNIFICANCE AND IMPACT OF THE STUDY This study can expand our understanding of cellular and molecular mechanisms of biofilm formation and also provide useful information for reducing biofilm-associated virulence potential.

Abstract
Data on the association between dietary vitamin K intake and fracture risk are limited among Chinese. This study examined such an association in community-dwelling elderly in Hong Kong. We present data from 2,944 subjects (1,605 men, 1,339 women) who participated in a prospective cohort study. Baseline dietary intakes of energy, protein, calcium, vitamin D, and vitamin K were assessed using a food-frequency questionnaire. Data on incident hip fracture and nonvertebral fracture during a median of 6.9 follow-up years were collected from a hospital database. Cox regression analyses were performed with adjustments for age, education attainment, smoking status, alcohol use, body mass index, hip bone mineral density, physical activity, use of calcium supplement, and energy-adjusted nutrient intakes. There were 29 (1.8 %) men and 19 (1.4 %) women with incident hip fractures and 97 (6.0 %) men and 88 (6.6 %) women with nonvertebral fractures. The median (interquartile range) of dietary vitamin K intake was 241.8 (157.5-360.8) and 238.9 (162.4-343.6) μg/day in men and women, respectively. Similar dietary vitamin K intakes were observed between subjects with hip or nonvertebral fractures and subjects without hip or nonvertebral fractures. In both men and women, dietary vitamin K intake was not associated with fracture risks at all measured sites in either crude or adjusted models. In Chinese community-dwelling elderly, hip or nonvertebral fracture risk was not associated with dietary vitamin K intake. The high dietary vitamin K intake of the studied group may have limited the ability to detect the association between vitamin K intake and fracture risk.

Abstract
UNLABELLED This study examines the association between sex steroids, bone mineral density (BMD), and incident fractures in 1,489 community-living Chinese men aged 65 and over. Chinese men with low serum estradiol levels display elevated bone loss and increased risk of fractures similar to findings in Caucasians. INTRODUCTION This study examines the association between serum total testosterone (TT), free testosterone (free T), estradiol (E(2)), bioavailable estradiol (bioE(2)), sex hormone binding globulin (SHBG), BMD, and incident fractures. METHODS This is a cohort study with 4-year follow-up in the community in Hong Kong SAR, China. One thousand four hundred eighty-nine community-living Chinese men aged 65 and over participated. Sex steroid levels and BMD were measured at baseline; BMD was repeated after 4 years of follow-up, and fracture incidence from ascertainment from hospital databases was determined over 4 years of follow-up. RESULTS The strongest age-adjusted positive association with total hip and femoral neck BMD was with bioE(2), followed by E(2). Greater bone loss occurred in the lowest quartile of E(2) and bioE(2). The lowest quartile of free T and bioE(2) and the two highest quartile of SHBG were associated with the highest percentage of participants with incident fractures. Those in the lowest quartile of E(2) and bioE(2) had approximately a 50% increased risk of incident fractures compared with the other three quartiles. This relationship remains significant for nonvertebral incident fractures (hip, radius, pelvis, and humerus) for E(2) only, but not bioE(2). Compared with the group with the three highest quartiles of TT and E(2), the group with the lowest quartile of both had approximately twice the risk of nonvertebral osteoporosis-related incident fractures. CONCLUSION Chinese men with low serum estradiol levels display elevated bone loss and increased risk of fractures similar to findings in Caucasians.

Abstract
UNLABELLED Calcaneal QUS is comparable to DXA in predicting non-vertebral fractures in older Chinese men. INTRODUCTION The predictive values of calcaneal quantitative ultrasound (QUS) and dual-energy X-ray absorptiometry (DXA) for non-vertebral fractures in older Chinese men were examined. METHODS One thousand nine hundred twenty-one Chinese men aged 65-92 years had calcaneal QUS and axial DXA bone mineral density (BMD) measurements. The incidence of non-vertebral fractures was documented. Cox regression and receiver operating curve (ROC) analysis were used to examine the associations of QUS parameters and BMD with the incidence of non-vertebral fractures. RESULTS The duration of follow-up was (mean ± SD) 6.5 ± 1.7 years. One hundred thirty-one non-vertebral fractures were recorded, 71 of which were major fragility fractures. Broadband ultrasound attenuation (BUA) and quantitative ultrasound index (QUI) were significantly associated with non-vertebral fractures and major fragility fractures, with age and fracture history-adjusted hazard ratio (95% CI) of 1.23 (1.03, 1.47) and 1.32 (1.10, 1.59) per standard deviation reduction, respectively, for non-vertebral fractures; 1.32 (1.04, 1.68) and 1.43 (1.11, 1.84), respectively, for major fragility fractures. Age and fracture history-adjusted areas under ROC curves of hip or spine BMDs were significantly greater than that of BUA or QUI in predicting major fragility fractures, but not in predicting all non-vertebral fractures. The addition of BUA or QUI had no effect on AUCs of total hip BMD alone. CONCLUSIONS The ability of calcaneal QUS to predict non-vertebral fractures was comparable to that of axial BMD by DXA, but was inferior to BMD in predicting major fragility fractures in older Chinese men.

Abstract
OBJECTIVE We examined the contribution of ACE I/D polymorphism in a large Chinese population to four year change in ankle-brachial index (ABI), development of cardiovascular diseases and mortality in a prospective study adjusting for many confounding factors. METHOD Data are drawn from a longitudinal study of 4000 community-living men and women aged 65 years and over, for which detailed information regarding lifestyle, chronic diseases, body mass index (BMI), ABI measurements and ACE polymorphisms were documented at baseline. During the fifth year of follow up, incident cardiovascular diseases, ABI, and mortality were documented, and related to ACE genotype adjusting for age, smoking, alcohol, dietary intake, physical activity, body mass index, and use of ACE inhibitors. RESULTS Women with the D/D genotype had the greatest reduction in mean ABI after adjusting for confounding factors. D/D genotype was also more common among women who developed hypertension or myocardial infarction. However D/D genotype was associated with mortality only in men. CONCLUSION In a Chinese elderly population, ACE polymorphism may be considered "deleterious" to longevity, the D/D genotype being associated with mortality, the atherosclerotic process, hypertension and myocardial infarction. There are gender differences in the relationship between D/D genotype and cardiovascular diseases and mortality may not be mediated by the atherosclerotic process alone.

Abstract
OBJECTIVE Vegetarians are more vascular-healthy but those with subnormal vitamin B-12 status have impaired arterial endothelial function and increased intima-media thickness. We aimed to study the impact of vitamin B-12 supplementation on these markers, in the vegetarians. DESIGN Double-blind, placebo controlled, randomised crossover study. SETTING Community dwelling vegetarians. PARTICIPANTS Fifty healthy vegetarians (vegetarian diet for at least 6 years) were recruited. INTERVENTION Vitamin B-12 (500 µg/day) or identical placebo were given for 12 weeks with 10 weeks of placebo-washout before crossover (n=43), and then open label vitamin B-12 for additional 24 weeks (n=41). MEASUREMENT Flow-mediated dilation of brachial artery (FMD) and intima-media thickness (IMT) of carotid artery were measured by ultrasound. RESULTS The mean age of the subjects was 45±9 years and 22 (44%) were male. Thirty-five subjects (70%) had serum B-12 levels <150 pmol/l. Vitamin B-12 supplementation significantly increased serum vitamin B-12 levels (p<0.0001) and lowered plasma homocysteine (p<0.05). After vitamin B-12 supplementation but not placebo, significant improvement of brachial FMD (6.3±1.8% to 6.9±1.9%; p<0.0001) and in carotid IMT (0.69±0.09 mm to 0.67±0.09 mm, p<0.05) were found, with further improvement in FMD (to 7.4±1.7%; p<0.0001) and IMT (to 0.65±0.09 mm; p<0.001) after 24 weeks open label vitamin B-12. There were no significant changes in blood pressures or lipid profiles. On multivariate analysis, changes in B-12 (β=0.25; p=0.02) but not homocysteine were related to changes in FMD, (R=0.32; F value=3.19; p=0.028). CONCLUSIONS Vitamin B-12 supplementation improved arterial function in vegetarians with subnormal vitamin B-12 levels, proposing a novel strategy for atherosclerosis prevention.

Abstract
OBJECTIVE Metabolic and atherosclerotic diseases are known risk factors for disability in old age, and can result in sarcopenia as well as cognitive impairment, which are both components of frailty syndrome. As muscle loss increases with ageing, it is unclear whether muscle loss per se, or the diseases themselves, are the underlying cause of physical frailty in those suffering from these diseases. We tested the hypothesis that metabolic and atherosclerotic diseases and cognitive impairment are associated with physical frailty independent of muscle loss in old age, and further examined their impact on the relationship between physical frailty and mortality. DESIGN Prospective. SETTING Community. PARTICIPANTS 4000 community dwelling Chinese elderly ≥65 years. MEASUREMENTS Diabetes, hypertension, stroke, heart disease, cognitive impairment, smoking, physical activity, waist hip ratio (WHR) and ankle-brachial index (ABI)) were recorded. Physical frailty measurements (grip-strength, chair-stands, stride length and 6-metre walks) were summarized into a composite frailty score (0-20), 0 being the most frail) according to quartiles of performance. Appendicular muscle mass (ASM) was measured using dual X-ray absorptiometry. Relationships between the score and covariates were analyzed. Cox regression was used to study the impact of metabolic and atnerosclerotic risk factors on the relationship between physical frailty and 6-year mortality. RESULTS After adjustment for ASM, all metabolic diseases and indexes, and cognitive impairment were significantly associated with the composite physical frailty score in univariate analysis. In multivariate analysis, cognitive impairment, high WHR, diabetes, stroke and heart disease were all independently associated with higher physical frailty with adjustment for age, physical activity level and ASM. Hypertension was associated with physical frailty in men but not in women. In Cox regression, increased physical frailty was associated with higher 6-year mortality. The impact of metabolic and atherosclerotic risk factors was however only modest after adjustment for age and cognitive function. CONCLUSION Metabolic and atherosclerotic diseases and high WHR, was associated with physical frailty, independent of their adverse effect on cognitive function and muscle mass.

Abstract
OBJECTIVES To examine the relationship between diabetes and impairments in functional and cognitive status as well as depression in older people. DESIGN Cross-sectional study. SETTING Elderly Health Centres (EHC) in Hong Kong. PARTICIPANTS 66,813 older people receiving baseline assessment at EHC in 1998 to 2001. MEASUREMENTS Diabetes status was defined by self-report and blood glucose tests. Functional status was assessed by 5 items of instrumental activities of daily living (IADL) and 7 items of activities of daily living (ADL). Cognitive status was screened by the Abbreviated Mental Test-Hong Kong version (AMT). Depressive symptoms were screened by the Geriatric Depression Scale-Chinese version (GDS). RESULTS Among the subjects, 10.4% reported having regular treatment for diabetes, 3.4% had diabetes but were not receiving regular treatment, and 86.2% did not have diabetes. After controlling for age, sex and education level, those having regular treatment for diabetes were 1.7 times more likely (OR=1.65, 95% CI: 1.51-1.80) to have functional impairment, 1.3 times more likely (OR=1.28, 95% CI: 1.11-1.48) to have cognitive impairment and 1.3 times more likely (OR=1.35, 95% CI: 1.25-1.46) to have depression, than older people without diabetes. CONCLUSION Older people with diabetes may be less capable of managing the disease than the younger ones as a result of increased risk of both physical and cognitive impairment. This study provided further evidence for the need of an international consensus statement regarding care of diabetes in older people.

Abstract
OBJECTIVE To examine the association between baseline frailty measurements and cognitive function 4 years later. DESIGN Prospective observational study. SETTING Community. PARTICIPANTS Two thousand seven hundred and thirty seven cognitively normal older adults. MEASUREMENT The appendicular muscle mass (ASM), hand grip strength, timed chair-stand test, walking speed and step length were measured at baseline. The Mini-mental state examination (MMSE) was administered at baseline and 4 years later. RESULTS In men, all baseline frailty measurements, namely, being underweight, lower ASM, weaker grip strength, slower chair-stand test, shorter step length, slower timed walk were significantly associated with a lower MMSE score 4 years afterwards. After adjustment for age, years of education and baseline MMSE score, ASM and timed walk became insignificant. In women, all frailty measurements except underweight and low ASM were significantly associated with MMSE score 4 years later. Moreover, only weaker grip strength persisted to be significant after adjustment for age, years of education and baseline MMSE score. CONCLUSION Physical frailty, as represented by being underweight, weaker grip strength, slower chair-stand test, shorter step-length in men and weaker grip strength in women, was associated with cognitive decline over a four year period.
