Abstract
Lateral wall thickness is a known predictor for postoperative stability of trochanteric femoral fractures and occurrence of secondary lateral wall fractures. Currently, the AO/OTA classification relies on the absolute lateral wall thickness (aLWT) to distinguish between stable A1.3 and unstable A2.1 fractures that does not take interpersonal patient differences into account. Thus, a more individualized and accurate measure would be favorable. Therefore, we proposed and validated a new patient-specific measure-the relative lateral wall thickness (rLWT)-to consider individualized measures and hypothesized its higher sensitivity and specificity compared with aLWT. First, in 146 pelvic radiographs of patients without a trochanteric femoral fracture, the symmetry of both caput-collum-diaphyseal angle (CCD) and total trochanteric thickness (TTT) was assessed to determine whether the contralateral side can be used for rLWT determination. Then, data of 202 patients were re-evaluated to compare rLWT versus previously published aLWT. Bilateral symmetry was found for both CCD and TTT (p ≥ 0.827), implying that bone morphology and geometry of the contralateral intact side could be used to calculate rLWT. Validation revealed increased accuracy of the rLWT compared with the gold standard aLWT, with increased specificity by 3.5% (Number Needed to Treat = 64 patients) and sensitivity by 1% (Number Needed to Treat = 75 patients). The novel rLWT is a more accurate and individualized predictor of secondary lateral wall fractures compared with the standard aLWT. This study established the threshold of 50.5% rLWT as a reference value for predicting fracture stability in trochanteric femoral fractures.

Abstract
PURPOSE/OBJECTIVE(S) This study aimed to evaluate the correlation between the extent of uterine body invasion and para-aortic lymph node (PALN) recurrence in patients with cervical carcinoma who received pelvic radiotherapy. MATERIALS/METHODS The data of 185 patients diagnosed with cervical carcinoma, initial stage IB to IVA without para-aortic lymph node metastasis, according to the FIGO 2009 Stage System, and treated between January 2011 and December 2016 were retrospectively analyzed. With using pelvic MRI with contrast, the extent of uterine body invasion was assessed and categorized into three types: non-uterine invasion, endocervical invasion, and invasion into the uterine body. Non-uterine invasion, by definition, referred to tumor located at the outer orifice of the cervix or ectocervix, while endocervical invasion referred to tumor invasion up to the endocervical canal, and the uterine body invasion referred to cervical carcinoma invading the uterine cavity from the squamocolumnar junction (SCJ) transformation zone. Definitive or adjuvant pelvic radiotherapy was given to the 185 patients, all of whom did not receive extended-field radiotherapy. The major result of PALN recurrence, defined as a short axial diameter of lymph node greater than 1cm, was diagnosed through computed tomography, pelvic MRI, or PET-CT. The actuarial rates of PALN recurrence were analyzed using Kaplan-Meier curves, and Cox regression models were used for multivariate analyses. RESULTS There were 122 (65.9%), 37 (20.0%), and 26 (14.1%) patients with non-uterine invasion, endocervical invasion, and invasion into the uterine body, respectively. The 5-year PALN recurrence rates were 7.8% in the non-uterine invasion group, 13.1% in the endocervical invasion group, and 21.1% in the uterine body invasion group (p = 0.009), after a median follow-up of 65.5 months. The multivariate analysis revealed that uterine body invasion was the only independent factor of PALN recurrence (p = 0.004). Factors such as initial pelvic lymphadenopathy (p = 0.645), initial SCC-Ag level (p = 0.200), non-squamous cell carcinoma (p = 0.882), and FIGO stage III-IVA (p = 0.289) were not significant factors of PALN recurrence. CONCLUSION This study demonstrates that cervical cancer patients with uterine body invasion have a higher risk of PALN recurrence following pelvic radiotherapy. Intensive follow-up schedules are recommended for these patients. Extended-field radiotherapy may be considered in cervical cancer patients with uterine body invasion to reduce PALN recurrence.

Abstract
Most oral squamous cell carcinoma (OSCC) tumors arise from oral premalignant lesions. Oral submucous fibrosis (OSF), usually occurring in male chewers of betel quid, is a premalignant stromal disease characterized by a high malignant transformation rate and high prevalence. Although a relationship between the inhabited microbiome and carcinogenesis has been proposed, no detailed information regarding the oral microbiome of patients with OSF exists; the changes of the salivary microbiome during cancer formation remain unclear. This study compared the salivary microbiomes of male patients with OSCC and a predisposing OSF background (OSCC-OSF group) and those with OSF only (OSF group). The results of high-throughput sequencing of the bacterial 16S rRNA gene indicated that OSF-related carcinogenesis and smoking status significantly contributed to phylogenetic composition variations in the salivary microbiome, leading to considerable reductions in species richness and phylogenetic diversity. The microbiome profile of OSF-related malignancy was associated with increased microbial stochastic fluctuation, which dominated the salivary microbiome assembly and caused species co-occurrence network collapse. Artificial intelligence selection algorithms consistently identified 5 key species in the OSCC-OSF group: Porphyromonas catoniae, Prevotella multisaccharivorax, Prevotella sp. HMT-300, Mitsuokella sp. HMT-131, and Treponema sp. HMT-927. Robust accuracy in predicting oral carcinogenesis was obtained with our exploratory and validation data sets. In functional analysis, the microbiome of the OSCC-OSF group had greater potential for S-adenosyl-l-methionine and norspermidine synthesis but lower potential for l-ornithine and pyrimidine deoxyribonucleotide synthesis and formaldehyde metabolism. These findings indicated that the salivary microbiome plays important roles in modulating microbial metabolites during oral carcinogenesis. In conclusion, our results provided new insights into salivary microbiome alterations during the malignant transformation of OSF.

Abstract
OBJECTIVE It has recently been reported that some COVID-19 patients have long-term positive fecal nucleic acid after discharging from the hospital with negative nucleic acid in the respiratory tract, but it is unclear whether COVID-19 patients with positive long-term fecal nucleic acid tests have the risk of self-infection. PATIENTS AND METHODS From January 25, 2020 to March 9, 2020, 5 COVID-19 patients with negative respiratory tract nucleic acid and positive fecal nucleic acid were observed and studied to explore whether these patients can re-infect themselves. Five patients with COVID-19 accompanied by diarrhea as the main gastrointestinal symptoms were carefully observed through clinical symptoms, imaging and other auxiliary examinations. The RT-PCR technology was used to continuously detect fecal and respiratory viral nucleic acids. The IgM antibody was detected on the 7th day of admission and IgM/IgG at the time of discharge. RESULTS All 5 patients had symptoms of fever and diarrhea upon admission. The fecal nucleic acid was positive, as well as the throat swab was positive. All COVID-19 patients had positive IgM antibodies on the 7th day of admission and positive IgM and IgG at the time of discharge, and there were no abnormalities in the gastrointestinal examination on discharge. All 5 fecal nucleic acid tests were positive at the time of discharge. After continuous dynamic follow-up for 3-15 days, no clinical symptoms recurred, and the last nucleic acid test was negative. CONCLUSIONS There is no risk of self-infection for COVID-19 patients with long-term 2019-nCoV nucleic acid positive in feces.

Abstract
Abstract
Background
Hypoglycemic episode (HE) increases the risk of cardiovascular mortality. The impact of HE on the risk of sudden death remains unclear. We hypothesized that HE increases the risks of ventricular arrhythmia (VA) and sudden cardiac arrest (SCA), and that anti-diabetic agents (ADAs) causing hypoglycemia also increase the risks of VA and SCA.
Methods
Patients aged ≥20 years with newly diagnosed diabetes were identified from the Taiwan National Insurance Database. HE was defined as the presentation of hypoglycemic coma or specified/unspecified hypoglycemia. For control group, we included diabetic patients without HE, and they were frequency-matched to the HE group at a 4:1 ratio. The primary outcome was the occurrence of any event of VA (including ventricular tachycardia and fibrillation) and SCA during the defined follow-up periods. Multivariate Cox hazards regression model was used to evaluate the hazard ratio (HR) for VA or SCA.
Results
A total of 54,303 diabetic patients were screened with 1,037 of them in the HE group, and 4,148 in the control group. During a mean follow-up period of 3.3±2.5 years, 29 VA/SCA events had occurred. Compared to the control group, the HE group had a higher incidence of VA/SCA (adjusted HR: 2.42, p=0.04). Diabetic patients medicated with insulin for glycemic control increased the risk of VA/SCA compared to those without insulin (adjusted HR: 3.05, p=0.01).
Kaplan-Meier survival curves
Conclusions
HEs in patients with diabetes increased the risks of VA and SCA compared to those without. Their use of insulin also independently increased the risk of VA/SCA.

Abstract
Sofosbuvir-velpatasvir is approved for the treatment of chronic hepatitis C virus (HCV) infection. In this single-arm, open-label, phase 3, deferred treatment study, we investigated the efficacy and safety of sofosbuvir-velpatasvir among patients randomized to the placebo group in the ASTRAL-1 study. Patients received sofosbuvir-velpatasvir (400/100 mg) once daily for 12 weeks. The primary efficacy endpoint was the proportion of patients with sustained virologic response 12 weeks after the end of therapy (SVR12). The primary safety endpoint was any adverse events (AEs) leading to the permanent discontinuation of study drug. Overall, 108/111 (97%, 95% confidence interval [CI], 92%-99%) achieved SVR12, and only one patient had virological failure. SVR12 was achieved by 61/63 (97%, 95%CI, 89%-100%) genotype 1 patients, 20/20 (100%; 95%CI, 83%-100%) with genotype 2, 19/19 (100%; 95%CI, 82%-100%) with genotype 4 and 8/9 (89%; 95% CI, 52%-100%) with genotype 6. All (19/19; 95%CI, 82-100) patients with cirrhosis and all (31/31, 95%CI, 89-100) with prior treatment experience achieved SVR12. The safety profile during treatment was similar to that observed in patients receiving placebo treatment. The most common AEs were headache, fatigue and nausea. One patient (1%) discontinued treatment due to an AE of gallbladder carcinoma, which was not considered related to treatment. Of five reported serious AEs, none were considered related to study drug. Sofosbuvir-velpatasvir for 12 weeks was effective and well tolerated among untreated and previously treated patients with HCV genotype 1, 2, 4 or 6 infection, including those with compensated cirrhosis (ClinicalTrials.gov NCT02346721).

Abstract
Background Patients chronically infected with genotype 3 hepatitis C virus (HCV) have faster disease progression and are less responsive to current direct-acting antiviral regimens than patients infected with other genotypes. We conducted an open-label trial to evaluate the safety, tolerability, and efficacy of ledipasvir and sofosbuvir plus ribavirin in patients with genotype 3 HCV infection. Methods We enrolled treatment-naive patients with and without compensated cirrhosis at 15 sites in Canada. All patients were treated with ledipasvir-sofosbuvir (90 mg and 400 mg) plus weight-based ribavirin for 12 weeks. The primary endpoint was sustained virologic response 12 weeks after treatment (SVR12). Secondary endpoints included evaluation of baseline and treatment-emergent drug resistance. Results Of the 111 patients enrolled, 105 (95%) had subtype 3a HCV and 39 (35%) had compensated cirrhosis. SVR12 was achieved by 99 of 111 patients (89%; 95% confidence interval, 82%-94%). Of the 39 patients with cirrhosis, 31 (79%) achieved SVR12, compared with 68 of 72 (94%) patients without cirrhosis. No treatment-emergent resistance mutations occurred in those who failed treatment. One patient discontinued treatment due to liver cancer and died 22 days after treatment discontinuation. The most common adverse events were fatigue (51%), headache (36%), and nausea (23%). Conclusions In this multicenter trial involving treatment-naive patients with genotype 3 HCV, 12 weeks of ledipasvir-sofosbuvir provided a high level of SVR in those without cirrhosis. Clinical Trials Registration NCT02413593.

Abstract
BACKGROUND & AIMS Treatment with direct-acting antiviral (DAA) agents can reduce Model for End-Stage Liver Disease and Child-Pugh-Turcotte (CPT) scores in patients with decompensated cirrhosis caused by hepatitis C virus. However, many of these patients still die or require liver transplantation. We collected data on baseline features of patients and aimed to develop a scoring system to predict response to DAA therapy. METHODS We performed a retrospective analysis of data from 4 trials on the effects of sofosbuvir-based therapy in patients with hepatitis C virus-associated decompensated cirrhosis (502 of CPT class B and 120 of CPT class C). In these trials, patients were given 12 or 24 weeks of treatment with ledipasvir, sofosbuvir, and ribavirin or velpatasvir, sofosbuvir, and/or ribavirin, or 48 weeks of treatment with sofosbuvir and ribavirin. We collected demographic, clinical, treatment response, and laboratory data from patients and tested their associations with patient outcomes at 36 weeks. The primary outcome was factors associated with reduction of CPT score to class A. RESULTS The presence of ascites or encephalopathy, serum level of albumin <3.5 g/dL or alanine aminotransferase <60 U/L, and body mass index >25 kg/m2 were associated with an increased risk of not achieving a reduction in CPT to class A, independent of sustained viral response to therapy. Serum level of albumin <2.8 g/dL and abnormal level of bilirubin were associated with an increased risk of liver transplantation or death. We developed a scoring system based on 5 baseline factors (body mass index, encephalopathy, ascites, and serum levels of alanine aminotransferase and albumin) associated significantly with patient outcomes, which we called the "BE3A score." For patients with scores of 4-5, the hazard ratio for reduction of CPT score to class A was 52.3 (95% confidence interval, 15.2-179.7). CONCLUSIONS We identified 5 baseline factors (body mass index, encephalopathy, ascites, and serum levels of alanine aminotransferase and albumin) associated with a reduction of CPT score to class A in patients with hepatitis C virus-associated decompensated cirrhosis receiving DAA therapy. We developed a predictive score using these factors, called the BE3A score, which can be used as a shared decision-making tool, quantifying the potential benefits of DAA therapy for patients with decompensated cirrhosis.

Abstract
UNLABELLED The optimal retreatment strategy for patients chronically infected with hepatitis C virus who experience virologic failure after treatment with direct-acting antiviral-based therapies remains unclear. In this multicenter, open-label, phase 2 study, we evaluated the efficacy and safety of a fixed-dose combination of sofosbuvir-velpatasvir (400 mg/100 mg) plus weight-adjusted ribavirin administered for 24 weeks in patients who did not achieve sustained virologic response after prior treatment with direct-acting antiviral regimens that included the nucleotide analogue nonstructural protein 5B inhibitor sofosbuvir plus the nonstructural protein 5A inhibitor velpatasvir with or without the nonstructural protein 3/4A protease inhibitor voxilaprevir. The primary efficacy endpoint was the proportion of patients achieving sustained virologic response at 12 weeks after the cessation of treatment. In total, 63 of 69 (91%; 95% confidence interval, 82%-97%) patients achieved sustained virologic response at 12 weeks, including 36 of 37 (97%; 95% confidence interval, 86%-100%) patients with hepatitis C virus genotype 1 infection, 13 of 14 (93%; 95% confidence interval, 66%-100%) patients with genotype 2 infection, and 14 of 18 (78%; 95% confidence interval, 52%-94%) patients with genotype 3 infection. Most adverse events were of mild or moderate severity. The most frequently reported adverse events were fatigue, nausea, headache, insomnia, and rash. One patient (1%) with genotype 1a infection discontinued all study drugs due to an adverse event (irritability). CONCLUSION Retreatment of patients who previously failed direct-acting antiviral-based therapies with sofosbuvir-velpatasvir plus ribavirin for 24 weeks was well tolerated and effective, particularly those with hepatitis C virus genotype 1 or 2 infection.

Abstract
OBJECTIVE This study aims to explore the treatment of methicillin-resistant staphylococcus aureus (MRSA) infection by using meta-analysis method. MATERIALS AND METHODS Pubmed/Medline, ScienceDirect, CNKI and Wanfang database were comprehensively searched to obtain the randomized controlled trials (RCTs) on linezolid and vancomycin in the treatment of MRSA infections. We extracted features and information of included studies and selected appropriate effect models based on the heterogeneity test results. The funnel plot was used to analyze publication bias. RESULTS A total of seven RCTs including 5376 cases met the inclusion criteria. Meta-analysis showed that the clinical cure rate of linezolid group was higher than that of vancomycin group after treatment (OR = 1.85; 95% CI: 1.33-2.59, p<0.001) and follow-up (OR = 1.49; 95% CI: 1.17-1.91, p=0.001). In the microbiologically evaluable patients, end of therapy (EOT) MRSA clearance rate, and test of cure (TOC) MRSA clearance rate of linezolid were superior to those of vancomycin. CONCLUSIONS Based on the combined analysis of randomized controlled trials, the efficacy of linezolid should be better than that of vancomycin in the treatment of infections caused by MRSA, but conclusions still need to be further validated by more well-designed RCTs of a large sample.

Abstract
UNLABELLED Hypoglycemia is a major concern in glycemic control. Using the Taiwan National Health Insurance Research Database, we found that the risk of hip fracture was associated with emergency or hospitalization visits of severe hypoglycemia in patients with type 2 diabetes; greater visits were associated with higher incidence of hip fracture. INTRODUCTION The objective of the study was to assess the risk of hip fracture among patients with type 2 diabetes mellitus (T2DM) and severe hypoglycemia. METHODS Using the National Health Insurance Research database in Taiwan, we identified 2588 patients with T2DM who had developed severe hypoglycemia from 2001 to 2009. A comparison cohort who had never developed severe hypoglycemia was frequency matched at a ratio of approximately 1:2. Multivariate Cox proportional hazard regression analysis was used to evaluate the risk of hip fracture. RESULTS During a median follow-up period of 3.9 years, there were 219 hip fracture events in 5173 comparison cohorts and 148 hip fracture events in 2588 hypoglycemia cohorts. The incidence of hip fracture was higher in patients with severe hypoglycemia than without severe hypoglycemia (17.19 vs. 8.83 per 1000 person-years; adjusted HR 1.71, 95% CI = 1.35-2.16). Approximately half of the individuals developed hip fracture within 2 years from the first occurrence of severe hypoglycemia. There was a significant associated trend towards increased hip fracture risk with increasing average visit of severe hypoglycemia per year (p for trend <0.001). Medication analysis showed that patients taking sulfonylurea alone, insulin alone, and insulin secretagogues combined with insulin had a higher associated risk to develop hip fracture. CONCLUSIONS Severe hypoglycemia was associated with a higher risk to develop hip fracture. The more the visits of severe hypoglycemia per year indicated the higher associated risk in patients with T2DM. Fall is likely an important reason for severe hypoglycemia in relation to increased risk of hip fracture.

Abstract
BACKGROUND A safe, simple, effective, and pan-genotypic regimen to treat hepatitis C virus (HCV) infection in patients coinfected with human immunodeficiency virus type 1 (HIV-1) remains a medical need. We assessed the efficacy and safety of the NS5B polymerase inhibitor sofosbuvir and the NS5A inhibitor velpatasvir for HCV in patients coinfected with HIV-1. METHODS This phase 3, open-label, single-arm study at 17 sites in the United States enrolled patients with HCV of any genotype and HIV-1 coinfection, including those with compensated cirrhosis. All patients received sofosbuvir-velpatasvir once daily for 12 weeks. The primary endpoint was sustained virologic response 12 weeks after treatment (SVR12). Efficacy and safety were assessed in all patients receiving at least 1 dose of treatment. RESULTS Of 106 patients, 91 (86%) were men, 48 (45%) were black, and 19 (18%) had cirrhosis. SVR12 was achieved by 101 of 106 (95% [95% confidence interval {CI}, 89%-99%]) patients: 74 of 78 (95% [95% CI, 87%-99%]) with genotype 1; all 11 (100% [95% CI, 72%-100%]) with genotype 2; 11 of 12 (92% [95% CI, 62%-100%]) with genotype 3; and all 5 (100% [95% CI, 48%-100%]) with genotype 4. All 19 patients with cirrhosis had SVR12. Two patients relapsed, 2 were lost to follow-up, and 1 withdrew consent. Two discontinued treatment due to adverse events and 2 had serious adverse events. The most common adverse events were fatigue (25%), headache (13%), upper respiratory tract infection (8%), and arthralgia (8%). CONCLUSIONS Sofosbuvir-velpatasvir for 12 weeks was safe and provided high rates of SVR12 in patients coinfected with HCV and HIV-1. CLINICAL TRIALS REGISTRATION NCT02480712.

Abstract
BACKGROUND Patients who are chronically infected with hepatitis C virus (HCV) and who do not have a sustained virologic response after treatment with regimens containing direct-acting antiviral agents (DAAs) have limited retreatment options. METHODS We conducted two phase 3 trials involving patients who had been previously treated with a DAA-containing regimen. In POLARIS-1, patients with HCV genotype 1 infection who had previously received a regimen containing an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive either the nucleotide polymerase inhibitor sofosbuvir, the NS5A inhibitor velpatasvir, and the protease inhibitor voxilaprevir (150 patients) or matching placebo (150 patients) once daily for 12 weeks. Patients who were infected with HCV of other genotypes (114 patients) were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. In POLARIS-4, patients with HCV genotype 1, 2, or 3 infection who had previously received a DAA regimen but not an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive sofosbuvir-velpatasvir-voxilaprevir (163 patients) or sofosbuvir-velpatasvir (151 patients) for 12 weeks. An additional 19 patients with HCV genotype 4 infection were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. RESULTS In the three active-treatment groups, 46% of the patients had compensated cirrhosis. In POLARIS-1, the rate of sustained virologic response was 96% with sofosbuvir-velpatasvir-voxilaprevir, as compared with 0% with placebo. In POLARIS-4, the rate of response was 98% with sofosbuvir-velpatasvir-voxilaprevir and 90% with sofosbuvir-velpatasvir. The most common adverse events were headache, fatigue, diarrhea, and nausea. In the active-treatment groups in both trials, the percentage of patients who discontinued treatment owing to adverse events was 1% or lower. CONCLUSIONS Sofosbuvir-velpatasvir-voxilaprevir taken for 12 weeks provided high rates of sustained virologic response among patients across HCV genotypes in whom treatment with a DAA regimen had previously failed.

Abstract
UNLABELLED This study estimated the fracture-related mortality and direct medical costs among postmenopausal women in Taiwan by fracture types and age groups by utilizing a nationwide population-based database. Results demonstrated that hip fractures constituted the most severe and expensive complication of osteoporosis across fracture sites. INTRODUCTION The aims of the study were to evaluate the risk of death and direct medical costs associated with osteoporotic fractures by fracture types and age groups among postmenopausal women in Taiwan. METHODS This nationwide, population-based study was based on data from the National Health Insurance Research Database in Taiwan. Female patients aged 50 years and older in the fracture case cohort were matched in 1:1 ratio with randomly selected subjects in the reference control cohort by age, income-related insurance amount, urbanization level, and the Charlson comorbidity index. There were two main outcome measures of the study: age-differentiated mortality and direct medical costs in the first and subsequent years after osteoporotic fracture events among postmenopausal women. The bootstrap method by resampling with replacement was conducted to generate descriptive statistics of mortality and direct medical costs of the case and control cohorts. Student's t tests were then performed to compare mortality and costs between the two cohorts. RESULTS A total of 155,466 postmenopausal women in the database met the inclusion criteria for the fracture case cohort, including 22,791 hip fractures, 72,292 vertebral fractures, 15,621 upper end humerus (closed) fractures, 36,774 wrist fractures, and 7,988 multiple fractures. Analytical results demonstrated that patients experiencing osteoporotic fractures were at considerable excess risk of death and incurred substantially higher treatment costs, notably for hip fractures. Furthermore, results also revealed that the risk of mortality increased with advancing age across the spectrum of fracture sites. CONCLUSIONS The present study confirmed an excess mortality and higher direct medical costs associated with osteoporotic fractures. Moreover, hip fractures constituted the most severe and expensive complication of osteoporosis among fracture types.

Abstract
Taiwan had been considered rabies free since 1961. In 2013, Taiwan confirmed the detection of rabies virus in wild Taiwan ferret-badgers. Up to December 2014, there have been 423 rabies-confirmed ferret-badgers and three cases of spillover infection into non-reservoir hosts. Genetic analysis indicates that TFBV is distinct from all other known rabies virus variants. To date, ferret-badger rabies is known to occur only in China and Taiwan. The temporal dynamics of rabid ferret-badgers in Taiwan suggests that the epizootic appears to have subsided to enzootic levels as of December 2014. According to the current epidemiologic data, there is only one TFBV strain in Taiwan. TFBV is still sequestered to the mountainous regions. Humans are at risk mainly through exposure to the virus from infected domestic meso-carnivores, mainly dogs and cats. Dogs and cats should be vaccinated to establish an immunological barrier to stop the spread of the disease from mountainous regions to domestic meso-carnivores.

Abstract
In patients with haemophilia A, repeated occurrences of haemarthrosis and synovitis lead to limitations in range of motion (ROM) of major joints. However, the effect of limitations in joint ROM on health-related quality of life (HRQOL) in these patients has not been studied previously. The aim of this study was to assess the impact of ROM limitations of 10 major joints (bilateral shoulders, elbows, hips, knees and ankles), combined with other possibly influential factors, on HRQOL in patients with haemophilia A. The ROM limitations in 13 movements and pain intensity of the 10 major joints were measured. The socio-demographic and clinical data were recorded. Short-Form 36 was used as the HRQOL measurement. Eighteen patients (mean age: 36.9 years) were included. Hip ROM limitations, knee ROM limitations and hip pain intensity predicted physical functioning scale (P < 0.001; adjusted R2 = 0.553). Shoulder ROM limitations and age predicted role limitation were due to emotional problems scale (P < 0.001; adjusted R2 = 0.373). Elbow ROM limitations and haemophilia severity predicted mental health scale (P = 0.001; adjusted R2 = 0.320). Hip ROM limitations predicted social functioning scale (P = 0.041; adjusted R2 = 0.091). Educational level and elbow ROM limitations predicted vitality scale (P < 0.001; adjusted R2 = 0.416). The ROM limitations of hip, knee, shoulder and elbow could be predictors for HRQOL in patients with haemophilia A. Improving ROM of major joints could be an appropriate treatment strategy to enhance HRQOL in these patients.

Abstract
PURPOSE ERG expression has been proposed to signify molecular subtype of PCA. However, its significance in early onset prostate cancer (PCA) is not characterized. MATERIALS AND METHODS ERG protein expression was investigated in a cohort of 121 men diagnosed with localized PCA at <50 years of age with a mean follow-up time of 65.7 months. ERG was correlated to patients' outcome and clinical-pathological parameters using univariate and multivariate analysis. RESULTS ERG expression was detected in 76/118 (64.4 %) analyzable patients' samples and showed interfocal heterogeneity (differences between foci) in 17/118 (14.4 %) patients. There was significant association between ERG expression and Gleason score (p = 0.022), but not with any other clinical-pathologic parameter, including pre-surgical PSA levels, tumor volume, pathological stage, surgical margin or lymph-vascular invasion. ERG had significant effect on the rate of biochemical relapse following radical prostatectomy, with ERG positive patients showing higher relapse rates vs. ERG negative patients (p = 0.007). However, considering time till biochemical relapse post-radical prostatectomy, ERG expression showed positive insignificant trends (p = 0.071). Notably, and of great significance, in this cohort of early onset disease, none of the ERG negative PCA patients exhibited biochemical relapse. CONCLUSION The study results suggest that ERG expression may be of added prognostic value in localized prostate cancer in patients with early onset PCA. However, the issue of ERG interfocal heterogeneity observed may require the evaluation of several tumor foci to assess ERG status per case. Incorporating ERG status into existing nomograms may be of added prognostic value in patients with early onset PCA.

Abstract
A marked decrease of klotho expression was observed in the kidney of streptozotocin-induced diabetic rats (STZ rats) showing diabetic nephropathy. It has been documented that klotho is the target gene of PPARγ. However, the effect of PPARγ agonist on klotho expression in kidney of STZ rats remains obscure. Thus, we used rosiglitazone (TZD) as PPARγ agonist to investigate the effect on renal dysfunction in STZ rats. Treatment of TZD reversed the lower levels of PPARγ, klotho, and FGFR1 expressions in kidneys of STZ rats without the correction of hyperglycemia. Also, renal functions and structural defeats were improved by TZD treatment. Taken together, oral administration of TZD may improve STZ-induced diabetic nephropathy due to restoration of the expression of klotho axis through an increase in PPARγ expression without changing blood glucose in rats.

Abstract
BACKGROUND The previous studies regarding the association between endogenous dehydroepiandrosterone (DHEA) sulphate level and metabolic syndrome are inconsistent. This study aimed to investigate such relationship in elderly Taiwanese men. MATERIALS AND METHODS Five hundred and eighty-five elderly Taiwanese men (mean age 68.7 +/- 8.3 years) were enrolled as the baseline cohort population in 2000. In addition to a questionnaire, body mass index (BMI), blood pressure, fasting blood glucose, lipids, albumin and serum DHEA-S levels were measured for each participant. Metabolic syndrome was based on the definition by the America Heart Association/National Heart Lung Blood Institute. RESULTS The prevalence of metabolic syndrome was 33.3%. Using multivariate logistic regression analyses with adjustments for age, smoking, alcohol, physical activities, albumin and BMI, there was a positive relationship between serum DHEA-S level and metabolic syndrome. The highest DHEA-S quartile group had increased risk for metabolic syndrome (odds ratio = 2.68, 95% confidence interval: 1.44-5.01, P < 0.01) compared with the lowest quartile group. The mean serum DHEA-S level increased with increasing number of metabolic syndrome components. CONCLUSIONS The prevalence of metabolic syndrome increases with elevated DHEA-S levels among elderly Taiwanese men. Thus, elevated serum DHEA-S level should be treated as an important risk factor for metabolic syndrome in elderly men.

Abstract
BACKGROUND AND OBJECTIVE Single nucleotide polymorphisms are assumed to be associated with the differential production of cytokines. We evaluated gene polymorphisms of interleukin-10 (-592C>A, -819C>T and -1082G>A) and interleukin-12B (+16974) in patients with chronic periodontitis (n = 145) and generalized aggressive periodontitis (n = 65) in comparison with healthy controls (n = 126). MATERIAL AND METHODS Gene promoter polymorphisms were analyzed by polymerase chain reaction with sequence-specific primers. Genotype and allele frequencies were analyzed using the chi-square test and logistic regression analysis. RESULTS The interleukin-10 -592 polymorphism showed significant differences among the three groups (p = 0.0330). The genotype frequencies of the -592 locus between the chronic periodontitis and healthy control groups were significantly different (AC vs. AA: odds ratio = 0.33). The combination ATA/ATA seemed to be associated with susceptibility to generalized aggressive periodontitis (p = 0.0276). Patients with the composite ATA/ACC were less likely to develop chronic periodontitis (p = 0.0248). The CC genotype of interleukin-12B (+16974) was related to chronic periodontitis (CC vs. AA, p = 0.0211; CC vs. AA+AC, p = 0.0187). The AC heterozygosity of interleukin-12B was significantly lower in chronic periodontitis vs. healthy controls (p = 0.0500). CONCLUSION The interleukin-10 gene polymorphism at position -592C>A may be associated with a lower risk for development of chronic periodontitis. The interleukin-10 haplotype ATA is associated with generalized aggressive periodontitis. On the other hand, interleukin-12B genetic variants at position +16974 are associated with susceptibility to chronic periodontitis.

Abstract
Nontyphoid Salmonella have a broad host range in poultry and mammals, and serovar Typhimurium is a threat to public health. In this study, normal and sick ducks and geese were collected from 12 farms in Taiwan to investigate the age-associated infection of Salmonella and Salmonella Typhimurium in Roman geese (Anser anser domesticus) and Pekin ducks (Anas platyrhynchos domesticus). In normal birds, the prevalence of Salmonella differed between species, and with age [e.g., 1-wk group, 37.5% (30/80) for ducks and 5.2% (6/116) for goslings (P < 0.05) vs. 4-wk group, 1% (1/96) for ducks and 12.1% (21/174) for geese]. Salmonella Typhimurium was identified from the visceral organs of moribund young geese suffering with colibacillosis and riemerellosis isolated from 2 goose farms (farm A and B, respectively). At farm B, 22.9% (27/118) of 4-wk geese with diarrhea were Salmonella Typhimurium-positive compared with 4.6% (8/174) of 4-wk normal geese. All Salmonella Typhimurium strains except one harbored a 94.7-kb virulence plasmid. Subcutaneous injection of Salmonella Typhimurium isolate 91NGL1 resulted in different clinical signs and pathogenesis between ducks and geese. In addition, the mean infectivity dose ratios of ducks to geese were 3.2 and 85.0 for 4- and 12-d birds, respectively, suggesting that goslings were more susceptible to Salmonella Typhimurium and resistance to Salmonella Typhimurium increased with age, especially for ducks. Therefore, Salmonella Typhimurium infection should be more common in goose farms than in duck farms, especially in the younger birds.

Abstract
BACKGROUND The prevalence of the metabolic syndrome (MetS) is high among the elderly. However, evidence that mortality increases with MetS is rare. In this study, we investigated the relationship between MetS, cardiovascular disease (CVD) and all cause mortality in the elderly. MATERIALS AND METHODS A total 10 547 participants, aged 65 years and older, of baseline cohort were recruited from four nationwide Health Screening Centres in Taiwan from 1998 to 1999. The metabolic syndrome was defined according to the America Heart Association/National Heart Lung Blood Institute definition. Cox proportional hazards regression analyses were used to estimate the relative risks (RRs) of CVD and all cause mortality for those with MetS for up to 8 years of follow-up. RESULTS The baseline prevalence of MetS was 50.1% (45.6% in men and 54.4% in women, respectively). A total of 1312 participants died; of these, 300 participants died from CVD. Adjusted for age, gender, smoking, total cholesterol and estimated glomerular filtration rate, the RRs for CVD and all cause mortality among participants with MetS were 1.48 (95% confidence interval = 1.16-1.90) and 1.16 (1.03-1.30), respectively, for participants compared to those without MetS. The mean RRs for CVD, however, ranged from 1.21 to 5.31 among different combinations of MetS components. CONCLUSION The elderly with MetS, compared to those without MetS, had a higher CVD and all cause mortality in Taiwan. Furthermore, different combinations of MetS components posed different risks to the mortality, which deserves further research in the future.

Abstract
Obesity is related to increased morbidity and mortality, and prevails worldwide. It has become an important health issue and requires urgent attention. In Taiwan, overweight and obesity are defined as body mass index > or = 24 and 27 kg m(-2), respectively. These cut-offs differ from Caucasian standards, as Asians have higher comorbidities and fat mass at lower BMI levels than Caucasians. The prevalence of obesity and overweight in Taiwan are 19.2% and 30.5% in men, 13.4% and 21.3% in women. This implies that a more profound increase in obesity prevalence is found in men than in women. A high-fat diet, sedentary lifestyle and betel nut chewing may increase substantially this obesity epidemic. Recently, type 2 diabetes mellitus has been found to be the most common type of diabetes, and obesity is significantly related to type 2 diabetes in children. In addition, obesity is associated with cardiovascular diseases risk factors and cannot be neglected in elderly. Therefore, a comprehensive prevention and management programme of obesity is urgently warranted for controlling the growing obesity trend and its related diseases in Taiwan.
