The potential prolonged effect at one-year follow-up after 18-month randomized controlled trial of a 90 g/day low-carbohydrate diet in patients with type 2 diabetes.

OBJECTIVES: To evaluate the effect at a one-year follow-up after an 18-month randomized controlled trial (RCT) of 90 gm/day low-carbohydrate diet (LCD) in type 2 diabetes. RESEARCH DESIGN AND METHODS: Eighty-five poorly controlled type 2 diabetic patients with an initial HbA1c ≥ 7.5% who have completed an 18-month randomized controlled trial (RCT) on 90 g/day low-carbohydrate diet (LCD) were recruited and followed for one year. A three-day weighted food record, relevant laboratory tests, and medication effect score (MES) were obtained at the end of the previous trial and one year after for a total of 30 months period on specific diet. RESULTS: 71 (83.5%) patients completed the study, 35 were in TDD group and 36 were in LCD group. Although the mean of percentage changes in daily carbohydrate intake was significantly lower for those in TDD group than those in LCD group (30.51 ± 11.06% vs. 55.16 ± 21.79%, p = 0.0455) in the period between 18 months and 30 months, patients in LCD group consumed significantly less amount of daily carbohydrate than patients in TDD group (131.8 ± 53.9 g vs. 195.1 ± 50.2 g, p < 0.001). The serum HbA1C, two-hour serum glucose, serum alanine aminotransferase (ALT), and MES were also significantly lower for the LCD group patients than those in the TDD group (p = 0.017, p < 0.001, p = 0.017, and p = 0.008 respectively). The mean of percentage changes of HbA1C, fasting serum glucose, 2 h serum glucose, as well as serum cholesterol, triglyceride, low-density lipoprotein, ALT, creatinine, and urine microalbumin, however, were not significantly different between the two groups (p > 0.05). CONCLUSIONS: The one-year follow-up for patients on 90 g/d LCD showed potential prolonged and better outcome on glycaemic control, liver function and MES than those on TDD for poorly controlled diabetic patients.

Mortality trends in chronic liver disease and cirrhosis from 1981 to 2015 in Taiwan.

BACKGROUND: Globally, the morbidity and mortality rates for chronic liver disease and cirrhosis are increasing. The National Viral Hepatitis Therapy Program in Taiwan was implemented in 2003, but evidence regarding the program's effect on the trends of mortality for chronic liver disease and cirrhosis is limited. METHODS: We analyzed mortality rates for chronic liver disease and cirrhosis in Taiwan for the period from 1981 to 2015. An autoregressive age-period-cohort model was used to estimate age, period, and cohort effects. RESULTS: Age-adjusted mortality rates for chronic liver disease and cirrhosis all displayed a flat but variable trend from 1981 to 2004 and a decreasing trend thereafter for both sexes. The age-period-cohort model revealed differential age gradients between the two sexes; mortality rates in the oldest age group (90-94 years) were 12 and 66 times higher than those in the youngest age group (30-34 years) for men and women, respectively. The period effects indicated that mortality rates declined after 2004 in both sexes. Mortality rates decreased in men but increased in women in the 1891-1940 birth cohorts and increased in both sexes in the birth cohorts from 1950 onward. CONCLUSIONS: The National Viral Hepatitis Therapy Program in Taiwan may have contributed to the decrease in mortality rates for chronic liver disease and cirrhosis in adulthood.

Effect of a 90 g/day low-carbohydrate diet on glycaemic control, small, dense low-density lipoprotein and carotid intima-media thickness in type 2 diabetic patients: An 18-month randomised controlled trial.

AIM: This study explored the effect of a moderate (90 g/d) low-carbohydrate diet (LCD) in type 2 diabetes patients over 18 months. METHODS: Ninety-two poorly controlled type 2 diabetes patients aged 20-80 years with HbA1c ≥7.5% (58 mmol/mol) in the previous three months were randomly assigned to a 90 g/d LCD r traditional diabetic diet (TDD). The primary outcomes were glycaemic control status and change in medication effect score (MES). The secondary outcomes were lipid profiles, small, dense low-density lipoprotein (sdLDL), serum creatinine, microalbuminuria and carotid intima-media thickness (IMT). RESULTS: A total of 85 (92.4%) patients completed 18 months of the trial. At the end of the study, the LCD and TDD group consumed 88.0±29.9 g and 151.1±29.8 g of carbohydrates, respectively (p < 0.05). The 18-month mean change from baseline was statistically significant for the HbA1c (-1.6±0.3 vs. -1.0±0.3%), 2-h glucose (-94.4±20.8 vs. -18.7±25.7 mg/dl), MES (-0.42±0.32 vs. -0.05±0.24), weight (-2.8±1.8 vs. -0.7±0.7 kg), waist circumference (-5.7±2.7 vs. -1.9±1.4 cm), hip circumference (-6.1±1.8 vs. -2.9±1.7 cm) and blood pressure (-8.3±4.6/-5.0±3 vs. 1.6±0.5/2.5±1.6 mmHg) between the LCD and TDD groups (p<0.05). The 18-month mean change from baseline was not significantly different in lipid profiles, sdLDL, serum creatinine, microalbuminuria, alanine aminotransferase (ALT) and carotid IMT between the groups. CONCLUSIONS: A moderate (90 g/d) LCD showed better glycaemic control with decreasing MES, lowering blood pressure, decreasing weight, waist and hip circumference without adverse effects on lipid profiles, sdLDL, serum creatinine, microalbuminuria, ALT and carotid IMT than TDD for type 2 diabetic patients.

Validation of Assaying Carcinoembryonic Antigen in Human Serum by Using Immunomagnetic Reduction.

Immunomagnetic reduction (IMR) is a method to assay biomolecules by utilizing antibody functionalized magnetic nanoparticles. For clinical validation, important analytic performances of assaying carcinoembryonic antigen (CEA) using IMR are characterized. Furthermore, IMR is applied to assay carcinoembryonic antigen (CEA) in human serum for clinical validation. A total of 118 healthy controls and 79 patients with colorectal cancer (CRC) are recruited in this study. For comparison, assays using chemiluminometric immunoassay (CLIA) are also done for quantizing CEA in these serum samples. The results reveal a high correlation in terms of serum CEA concentration detected via IMR and CLIA is found (r = 0.963). However, IMR shows higher clinical sensitivity and specificity than those of CLIA. Moreover, the rate of false positives for smoking subjects is clearly reduced through the use of IMR. All the results demonstrate IMR is a promising alternative assay for serum CEA to diagnose CRC.

Tour leaders with detailed knowledge of travel-related diseases play a key role in disease prevention.

In Taiwan, group tours are a popular mode of international travel; hence, group tour leaders must ensure traveler safety and health. This study identified factors influencing tour leaders' willingness to recommend pretravel medical consultation and vaccination.A cross-sectional questionnaire survey was administered to tour leaders from January 2011 to December 2012. Multivariate logistic regression analyses were performed to estimate the odds ratios of having a positive attitude and willingness based on different knowledge scores of the tour leaders after adjustments for age, sex, education level, and seniority.Tour leaders with a more detailed knowledge of both travel-related infectious and noninfectious diseases demonstrated a higher willingness to receive vaccination. They believed that consultation at travel clinics before travel can improve travelers' health (P < .05).This study supports the importance and effectiveness on educating tour leaders' knowledge about travel-related diseases to improve health care for travelers.

High serum selenium levels are associated with increased risk for diabetes mellitus independent of central obesity and insulin resistance.

OBJECTIVE: Selenium is an essential micronutrient for human health. Although many observational and interventional studies have examined the associations between selenium and diabetes mellitus, the findings were inconclusive. This study aimed to investigate the relationship between serum selenium levels and prevalence of diabetes, and correlated the relationship to insulin resistance and central obesity. RESEARCH DESIGN AND METHODS: This was a hospital-based case-control study of 847 adults aged more than 40 years (diabetes: non-diabetes =1:2) in Northern Taiwan. Serum selenium was measured by an inductively coupled plasma-mass spectrometer. The association between serum selenium and diabetes was examined using multivariate logistic regression analyses. RESULTS: After adjusting for age, gender, current smoking, current drinking, and physical activity, the ORs (95% CI, p value) of having diabetes in the second (Q2), third (Q3), and fourth (Q4) selenium quartile groups were 1.24 (95% CI 0.78 to 1.98, p>0.05), 1.90 (95% CI 1.22 to 2.97, p<0.05), and 5.11 (95% CI 3.27 to 8.00, p<0.001), respectively, compared with the first (Q1) quartile group. Further adjustments for waist circumference and homeostatic model assessment-insulin resistance (HOMA-IR) largely removed the association of serum selenium levels with diabetes but not in the highest quartile (compared with Q1, Q3: 1.57, 95% CI 0.91 to 2.70, Q4: 3.79, 95% CI 2.17 to 6.32). CONCLUSIONS: We found that serum selenium levels were positively associated with prevalence of diabetes. This is the first human study to link insulin resistance and central obesity to the association between selenium and diabetes. Furthermore, the association between selenium and diabetes was independent of insulin resistance and central obesity at high serum selenium levels. The mechanism behind warrants further confirmation.

Association of Non-alcoholic Fatty Liver Disease with Metabolic Syndrome Independently of Central Obesity and Insulin Resistance.

Non-alcoholic fatty liver disease (NAFLD) is an emerging chronic liver disease that may lead to liver cirrhosis and hepatocellular carcinoma. We aimed to determine the association between the prevalence of metabolic syndrome (MetS) and NAFLD severity using semi-quantitative ultrasonography (US). A total of 614 participants were recruited from the community. NAFLD was evaluated according to the ultrasonographic Fatty Liver Indicator (US-FLI), which is a semi-quantitative liver ultrasound score. Insulin resistance was estimated with the homeostasis model assessment index for insulin resistance (HOMA-IR). NAFLD and MetS were found in 53.7 and 17.3% of the participants, respectively. Linear relationships were found between the severity of NAFLD and waist circumference, fasting glucose, HOMA-IR, triglycerides, HDL-C and blood pressure. After adjusting for confounding factors, i.e., body mass index and HOMA-IR, the odds ratios for MetS were 3.64 (95% confidence interval (CI): 1.5-8.83) for those with mild NAFLD and 9.4 (95% CI: 3.54-24.98) for those with moderate-to-severe NAFLD compared to those without NAFLD. The combination of the HOMA-IR and US-FLI scores better differentiated MetS than the HOMA-IR alone. In addition to obesity, the severity of NAFLD and the HOMA-IR both play important roles in MetS. Whether NAFLD is a component of MetS warrants further research.

The Association between Total Protein and Vegetable Protein Intake and Low Muscle Mass among the Community-Dwelling Elderly Population in Northern Taiwan.

Sarcopenia, highly linked with fall, frailty, and disease burden, is an emerging problem in aging society. Higher protein intake has been suggested to maintain nitrogen balance. Our objective was to investigate whether pre-sarcopenia status was associated with lower protein intake. A total of 327 community-dwelling elderly people were recruited for a cross-sectional study. We adopted the multivariate nutrient density model to identify associations between low muscle mass and dietary protein intake. The general linear regression models were applied to estimate skeletal muscle mass index across the quartiles of total protein and vegetable protein density. Participants with diets in the lowest quartile of total protein density (<13.2%) were at a higher risk for low muscle mass (odds ratio (OR) 3.03, 95% confidence interval (CI) 1.37-6.72) than those with diets in the highest quartile (≥17.2%). Similarly, participants with diets in the lowest quartile of vegetable protein density (<5.8%) were at a higher risk for low muscle mass (OR 2.34, 95% CI 1.14-4.83) than those with diets in the highest quartile (≥9.4%). Furthermore, the estimated skeletal muscle mass index increased significantly across the quartiles of total protein density (p = 0.023) and vegetable protein density (p = 0.025). Increasing daily intakes of total protein and vegetable protein densities appears to confer protection against pre-sarcopenia status.

Relationship between chronic hepatitis B and metabolic syndrome: A structural equation modeling approach.

OBJECTIVE: Investigate the nature of the relationship between chronic hepatitis B virus (HBV) infection and metabolic syndrome among nondiabetic adults. METHODS: This was a cross-sectional analysis of 17,030 nondiabetic adults (7437 males and 9593 females; mean age, 36.0 ± 3.9 years) in northern Taiwan from 2008 to 2009. The associations of hepatitis B surface antigen (HBsAg) seropositivity with metabolic syndrome and cardio-metabolic parameters were assessed. A structural equation model was constructed to elucidate the pathways between chronic HBV infection and individual cardiometabolic risk factors. RESULTS: A total of 2982 (17.5%) participants were HBsAg-seropositive. Of the seropositive and seronegative subjects, 15.5 and 16.9% had metabolic syndrome, respectively. The HBsAg-seropositive subjects had a lower odds of having metabolic syndrome compared with the seronegative subjects irrespective of gender and age (OR: 0.76, 95% CI: 0.68-0.85). The inverse associations remained significant after adjusting for body mass index and serum alanine aminotransferase levels. HBsAg seropositivity was inversely associated with hypertriglyceridemia (OR: 0.59, 95% CI: 0.52-0.66), and low serum levels of high-density lipoprotein cholesterol (OR: 0.86, 95% CI: 0.79-0.93) after adjustments. The structural equation model revealed chronic HBV infection had a significant negative effect on dyslipidemia both in males (B = -0.054) and females (B = -0.064). CONCLUSIONS: The inverse relationship between chronic HBV infection and metabolic syndrome may be attributable to the net beneficial effects on lipid profiles.

Cancer incidence in the vicinity of nuclear power plants in Taiwan: a population-based study.

Numerous antinuclear demonstrations reveal that the public is anxious about the potential health effects caused by nuclear power plants. The purpose of this study is to address the question "Is there a higher cancer incidence rate in the vicinity of nuclear power plants in Taiwan?" The Taiwan Cancer Registry database from 1979 to 2003 was used to compare the standardized incidence rate of the top four cancers with strong evidence for radiation risks between the "plant-vicinity" with those "non-plant-vicinity" groups. All cancer sites, five-leading cancers in Taiwan, and gender-specific cancers were also studied. We also adopted different observation time to compare the incidence rate of cancers between two groups to explore the impact of the observation period. The incidences of leukemia, thyroid, lung, and breast cancer were not significantly different between two groups, but cervix uteri cancer showed higher incidence rates in the plant-vicinity group. The incidence of cervical cancer was not consistently associated with the duration of plant operation, according to a multiyear period comparison. Although there was higher incidence in cervix cancer in the plant-vicinity group, our findings did not provide the crucial evidence that nuclear power plants were the causal factor for some cancers with strong evidence for radiation risks.

Serum Triglyceride Levels Independently Contribute to the Estimation of Visceral Fat Amount Among Nondiabetic Obese Adults.

Determining the visceral fat amount is important in the risk stratification for the prevention of type 2 diabetes and obesity-related disorders. The area-based measurement of visceral fat area (VFA) via magnetic resonance imaging (MRI) is an accurate but expensive and time-consuming method for estimating visceral fat amount. The aim of our study was to identify a practical predictive parameter for visceral obesity in clinical settings. In this cross-sectional study, we recruited 51 nondiabetic obese (body mass index [BMI] ≥ 27 kg/m²) adults in Taiwan (21 men and 30 women, mean age 35.6 ±â€Š9.2 years, mean BMI 33.3 ±â€Š3.9 kg/m²). VFA was quantified by a single-slice MRI image. Anthropometric indices and biochemical parameters including fasting plasma glucose, serum level of alanine aminotransferase, and lipid profiles were measured. The associations between different variables and VFA were analyzed by linear regression analysis. Increases in BMI, waist circumference, serum levels of alanine aminotransferase and triglycerides (TGs), and decreased serum levels of high-density lipoprotein cholesterol were correlated with larger VFA. After adjustment for age, sex, and anthropometric indices, only serum TG level remained as an independent correlate of VFA. Besides demographic and anthropometric indices, adding TG level may explain a greater variance of VFA. In stepwise multivariate regression analysis, male sex, age, waist circumference, and serum TG level remained significant predictors of VFA. In a subgroup analysis among subjects with BMI ≥30 kg/m², similar results were demonstrated and serum TG level remained as significant independent correlates of VFA in all of the predictive models. Among nondiabetic obese adults, serum TG level was positively associated with VFA. The combination of sex, age, anthropometric indices, and serum TG level may be used to estimate VFA in clinical settings.

Low intensive lifestyle modification in young adults with metabolic syndrome a community-based interventional study in Taiwan.

The study aims to find whether a low intensity lifestyle modification (LILM) program was effective to achieve weight reduction and improves metabolic syndrome in young adults. Our study prospectively enrolled young adults aged 30 to 45 years with metabolic syndrome in northeastern Taiwan from June 1, 2008 to December 31, 2009. The participants in the intervention group attended a LILM program for 6 months, which included 4 interactive group discussion sessions and weekly phone contact with volunteer counselors. Participants in the comparison group, however, attended only 1 noninteractive session on diet and physical activity. The main outcomes measured the weight reduction and prevalence of metabolic syndrome in intervention and comparison groups. Generalized estimating equation modeling was used to analyze the effects at baseline, during the study, and postcompletion of the program. Compared with comparison group, the intervention group showed significantly greater reductions in body weight (-2.95 ±â€Š3.52 vs -0.76 ±â€Š2.76  kg, P < 0.0001) and body mass index (-1.03 ±â€Š1.25 vs -0.30 ±â€Š1.16  kg/m(2), P < 0.0001). After adjustment for potential confounders, a modest decrease in body weight resulted in a statistically significant 43.32% resolution in the prevalence of metabolic syndrome in the intervention group compared with 33.64% in the comparison group (P < 0.01).The 6-month LILM program is not only effective in weight reduction but also an efficient intervention tool of metabolic syndrome in a community setting. The program with restricted manpower and limited medical resources can be practically transferred into primary care in rural area.

Plasma zinc α2-glycoprotein levels are elevated in smokers and correlated with metabolic syndrome.

BACKGROUND: Smoking is a strong risk factor of metabolic syndrome. Zinc α2-glycoprotein (ZAG) is a protein involved in metabolic syndrome. This study aims to investigate the effect of smoking on plasma ZAG levels and its relations to metabolic syndrome. MATERIALS AND METHODS: A group of 41 cigarette smokers and 47 non-smokers were enrolled. ZAG levels were measured to correlate to participants' demographic and metabolic parameters. RESULTS: Plasma ZAG levels of smokers were higher than those of controls (P < 0.0001). Plasma ZAG levels were positively correlated with male gender (P = 0.0002), number of cigarettes smoked per day (P < 0.0001), smoking duration in years (P < 0.0001), smoking index (P < 0.0001) and nicotine dependence score (P < 0.0001). In the multiple regression analysis, smoking was a strong independent factor affecting plasma ZAG levels (P = 0.0034). Plasma ZAG levels elevated progressively with the number of metabolic syndrome components (P = 0.0143). In the multiple regression analysis, plasma ZAG was an independent factor for metabolic syndrome. CONCLUSIONS: Plasma ZAG levels are high in smokers and correlate with metabolic syndrome. Our results indicate ZAG is an independent risk factor, but also interacted with smoking, for the metabolic syndrome.

Wishes of Patients With Terminal Cancer and Influencing Factors Toward the Use of Antibiotics in Taiwan.

CONTEXT: The use of antibiotics is a common ethical dilemma in palliative care, thus identifying the concerns of patients with terminal cancer and respecting their wishes are important in making an ethically justified decision. OBJECTIVES: The aim of this study was to understand wishes of patients with terminal cancer and determine influencing factors toward the use of antibiotics. METHODS: Two hundred and one patients with terminal cancer, admitted to a palliative care unit in Taiwan, completed a structured questionnaire interview, including demographic characteristics, knowledge and attitudes on antibiotics, the health locus of control, subjective norms, and the wishes to use antibiotics. RESULTS: The most common misconception was "Antibiotics use is helpful to all terminal patients with infection," which only 13.4% respondents disagreed. Of the 201patients, 92 (45.8%) expressed their wishes to use antibiotics even in the very terminal stage, and around one-fourth (26.4%) of patients wished not to use antibiotics, the remaining 27.8% were unclear. The most influential persons were medical professionals. The results of logistic regression analysis that showed familiarity with antibiotics, subjective norms, and the attitude toward burdens of antibiotics were the most significant predicting variables for those wishing to use antibiotics (odds ratio [OR] = 4.133, 95% confidence interval [CI] = 1.012-16.880; OR = 1.890, 95% CI = 1.077-3.317; and OR = 1.255, 95% CI = 1.047-1.503). CONCLUSION: This study indicated the responsibility of medical professionals to convey burdens of using antibiotics to patients and family. Otherwise, by enhancing professional training and performing effective communication with patients, we can reach a more appropriate decision in the use of antibiotics.

Vitamin D status and risk of metabolic syndrome among non-diabetic young adults.

BACKGROUND AND AIMS: Low vitamin D status has been linked to obesity, insulin resistance, and metabolic syndrome. In the present study, we aimed to explore the nature and strength of the relationship between vitamin D and metabolic syndrome among non-diabetic young adults. METHODS: This was a campus-based cross-sectional study of 355 non-diabetic young adult graduate students (233 males and 132 females; mean age, 23.5 ± 2.4 years) in Northern Taiwan. We measured and tested the association of serum 25-hydroxyvitamin D levels with metabolic syndrome and cardio-metabolic parameters. RESULTS: A total of 24 (6.8%) recruited young adults had metabolic syndrome. There were decreasing trends of body mass index (BMI), Homeostasis Model of Assessment-Insulin Resistance (HOMA-IR) and prevalence of metabolic syndrome across increasing tertiles of vitamin D levels irrespective of age and sex (P for trend <0.05). Without adjusting for BMI or HOMA-IR, the odds of having metabolic syndrome decreased across increasing tertiles of vitamin D levels (P for trend 0.021). The odds ratio of having metabolic syndrome was 0.26 (95% confidence interval: 0.08-0.85, P = 0.025) for the highest vs. the lowest tertile of vitamin D levels. However, further adjustments for BMI and HOMA-IR largely removed the inverse association of vitamin D status with metabolic syndrome and its individual components. CONCLUSION: Among non-diabetic young adults, the potential inverse relationship between vitamin D status and metabolic syndrome may be attributable to the conjunctive effects of individual obesity and insulin resistance.

Low serum selenium level is associated with low muscle mass in the community-dwelling elderly.

OBJECTIVES: Elderly persons with low muscle mass (LMM) or sarcopenia are prone to frailty and functional decline. This study aimed to investigate the relationship between serum selenium level and skeletal muscle mass in community-dwelling elderly. DESIGN: Cross-sectional observational study. SETTING AND PARTICIPANTS: A total of 327 elderly Taipei citizens (mean age 71.5 ± 4.7 years) were recruited from the community. MEASUREMENTS: Skeletal muscle mass was measured by bioelectrical impedance analysis. LMM was defined by low skeletal muscle index (SMI: muscle mass (kg)/[height (m)](2)). All participants were further divided into quartiles by serum selenium level and the risk for LMM among these quartiles was examined using multivariate logistic regression analyses. Estimated serum selenium levels for the LMM group vs the normal group and estimated SMI in the quartiles of serum selenium were computed by least square method in linear regression models. RESULTS: The estimated mean (±standard deviation) of serum selenium level was significantly lower in the LMM group compared with the normal group after adjusting for confounders (1.01 ± 0.03 µmol/L vs 1.14 ± 0.02 µmol/L, P < .001). After adjusting for age, sex, lifestyle, and physical and metabolic factors, the odds ratios (95% confidence interval, P value) of LMM in the bottom, second, and third selenium quartile groups were 4.62 (95% CI 2.11-10.10, P < .001), 2.30 (95% CI 1.05-5.03, P < .05) and 1.51 (95% CI 0.66-3.46, P = .327), respectively, compared with the top quartile group of serum selenium level. The least square mean of SMI increased with the quartiles of serum selenium (P < .001). CONCLUSIONS: This is the first study to demonstrate that low serum selenium is independently associated with low muscle mass in the elderly. The causality and underlying mechanism between selenium and low muscle mass or sarcopenia warrant further research.

Opposite association between diabetes, dyslipidemia, and hepatocellular carcinoma mortality in the middle-aged and elderly.

UNLABELLED: Limited data exist regarding metabolic risk factors for deaths from hepatocellular carcinoma (HCC) in aging individuals. We investigated the association between diabetes, dyslipidemia, and HCC mortality in those aged 40 years or more (middle-aged and elderly). In this prospective cohort study based on nationwide health screening units, we consecutively followed middle-aged and elderly participants who had no chronic hepatitis B or C virus infection and received health screening from January 1 1998 to December 31 2008. There were 235 deaths from HCC among 50,080 individuals, ascertained by validated death certificates and the national death registry. Diabetes (adjusted hazard ratio [HR], 3.38; 95% confidence interval [CI], 2.35 to 4.86) was positively associated with deaths from HCC. However, hypertriglyceridemia (HR, 0.38; 95% CI, 0.26 to 0.55) and hypercholesterolemia (HR, 0.50; 95% CI, 0.37 to 0.67) were inversely associated with HCC mortality. The above significant associations remained in the lag time analyses, applied to check for reverse causation. Metabolic syndrome, as defined by the American Heart Association / National Heart Lung Blood Institute criteria (HR, 0.63; 95% CI, 0.46 to 0.86) or by the International Diabetes Federation criteria (HR, 0.62; 95% CI, 0.43 to 0.89), was inversely associated with deaths from HCC, especially in men. CONCLUSION: Middle-aged and elderly individuals, once having diabetes, deserve HCC surveillance to reduce HCC mortality. More research is needed to elucidate why having baseline dyslipidemia relates to lower future HCC mortality.

Sarcopenic obesity is closely associated with metabolic syndrome.

OBJECTIVES: Obesity is a risk factor for metabolic syndrome (MetS). We aimed to investigate whether sarcopenic obesity (SO) was associated with MetS. METHODS: A total of 600 community-dwelling males and females aged 63.6 ± 10.1 years in Northern Taiwan were enrolled in this study. Sarcopenia was defined by the percentage of total skeletal mass (total skeletal muscle mass (kg)/weight (kg) x 100). Cut-offs were established at <37% in men and <27.6% in women using the bioelectrical impedance analysis (BIA) method. Obesity was defined as body mass index (BMI) ≥25 kg/m(2). MetS was defined by the consensus of National Cholesterol Education Program-Adult Treatment Panel III modified for Asians. The association between MetS and SO was examined using multivariate logistic regression analyses after controlling potential confounders. RESULTS: The SO group demonstrated a higher risk for MetS (odds ratio [OR] 11.59 [95% confidence interval [CI] 6.72-19.98]) than the obese group (7.53 [4.01-14.14]) and sarcopenic group (1.98 [1.25-3.16]). The individual components including waist circumference, serum triglycerides, high-density lipoprotein cholesterol (HDL-C), and fasting serum glucose were independently associated with SO. CONCLUSION: SO is a major risk factor for MetS. The BIA method and BMI can easily identify subjects at high risk for MetS. The underlying mechanism for the relationship between SO and MetS warrants further research.

Is it appropriate to withdraw antibiotics in terminal patients with cancer with infection?

BACKGROUND: Antibiotic administration is frequent in terminal patients with cancer, yet the effects on survival are still under debate. OBJECTIVE: The aim of this study was to examine the status of infection and the benefit/burden of antibiotic administration on the survival of terminal patients with cancer with infection. DESIGN: A prospective observational study. SETTING/SUBJECTS: We studied 799 patients with terminal cancer who were admitted to a palliative care unit in Taiwan between January 2008 and the end of April 2010. Survival was calculated from the first day of admission to the day of death in the palliative care unit or under home care. MEASUREMENTS: A specially designed assessment tool was used daily to evaluate clinical conditions. Afterwards, it was analyzed at different time points in a weekly team meeting. Multivariate Cox proportional hazard analyses were used to examine the benefit/burden of antibiotic administration on survival. RESULTS: Four hundred fifty-five patients were diagnosed as having at least one episode of infection after first admission. A total of 295 of the 378 (78.0%) with infection received antibiotic treatment upon admission. Multivariate Cox proportional hazard analyses showed that antibiotic administration was related to improved survival for patients who were still alive 1 week after admission (hazard ratio: 0.66, 95% confidence interfal [CI]: 0.46-0.95). However, antibiotics would be a hazard to patients' survival if used in the time 2 days prior to death (hazard ratio: 1.54, 95% CI: 1.22-1.94). CONCLUSIONS: The results suggest that with good communication between patients, families, and medical staff, withdrawal of antibiotics should be considered if signs of death appear, in order to avoid unnecessary risks. The possible benefit of prolonged survival should be in line with the goal of care, and also take into account preparing the patient for a dignified death.
