Uremic pruritus is common among patients with advanced or end-stage renal disease, with an incidence of &gt, 40% among patients on dialysis. Uremic clearance granules (UCGs) are effective in managing uremic pruritus and delay the progression of chronic kidney disease. We conducted a systematic review and a meta-analysis to evaluate the efficacy of UCG in patients with uremic pruritus. Several electronic databases were searched systematically from their inceptions until 19 July 2021. Randomized control trials evaluating the efficacy of UCG in patients with uremic pruritus were selected. Eleven trials including 894 participants were published between 2011 and 2021. Patients administered UCGs had a significantly decreased visual analog scale score (mean difference [MD], −2.02, 95% confidence interval [CI], −2.17 to −1.88), serum levels of hsCRP (MD, −2.07 mg/dL, 95% CI, −2.89 to −1.25, p &lt, 0.00001), TNF-α (MD, −15.23 mg/L, 95% CI, −20.00 to −10.47, 0.00001]), β2-MG (MD, −10.18 mg/L, 95% CI, −15.43 to −4.93, 0.00001), and IL-6 (MD, −6.13 mg/L, 95% CI, −7.42 to −4.84, 0.00001). In addition, UCGs significantly reduced serum levels of creatinine, BUN, PTH, iPTH, phosphorus, and the overall effectiveness rate. UCGs could be an attractive complementary therapy for patients with uremic pruritus.

We included COPD patients who used inhalation steroid and beta-blockers between 1998 and 2010. From this cohort, there were 16,067 patients with severe exacerbations included in the analysis and 55,970 controls matched on age, sex, COPD diagnosis year, and beta-blockers treatment duration by risk set sampling.Results: For the selective beta-blocker users, the current users had a lower risk of severe exacerbations than the nonusers (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.85–0.96). In contrast, for the nonselective beta-blocker users, the current users had a higher risk of severe acute exacerbations than the nonusers (OR, 1.21; 95% CI, 1.14–1.27). A higher risk of severe exacerbation during increasing mean daily dose or within about the initial 300days was found in nonselective beta-blockers, but not in selective beta-blockers. One selective beta-blocker, betaxolol, had a significantly lower risk of severe exacerbations (OR, 0.75; 95% CI, 0.60–0.95). Two nonselective beta-blockers (labetalol and propranolol) were associated with a significantly higher risk of exacerbations (OR, 1.49; 95% CI, 1.32–1.67 for labetalol; OR, 1.16; 95% CI, 1.10–1.23 for propranolol).Conclusion: Selective beta-blockers can be cautiously prescribed for patients with COPD and cardiovascular disease (CVD), however, nonselective beta-blockers should not be prescribed for patients with COPD. Betaxolol may be the preferred choice of suitable selective beta-blocker for patients with COPD, however, labetalol and propranolol should be avoided for patients with COPD.

Obesity is associated with metabolic endotoxemia, reactive oxygen species (ROS), chronic inflammation, and obese kidney fibrosis. Although the fat&ndash, intestine&ndash, kidney axis has been documented, the pathomechanism and therapeutic targets of obese kidney fibrosis remain unelucidated. To mimic obese humans with metabolic endotoxemia, high-fat-diet-fed mice (HF group) were injected with lipopolysaccharide (LPS) to yield the obese kidney fibrosis&ndash, metabolic endotoxemia mouse model (HL group). Therapeutic effects of ROS, cytosolic phospholipases A2 (cPLA2) and cyclooxygenase-2 (COX-2) inhibitors were analyzed with a quantitative comparison of immunohistochemistry stains and morphometric approach in the tubulointerstitium of different groups. Compared with basal and HF groups, the HL group exhibited the most prominent obese kidney fibrosis, tubular epithelial lipid vacuoles, and lymphocyte infiltration in the tubulointerstitium. Furthermore, inhibitors of nonspecific ROS, cPLA2 and COX-2 ameliorated the above renal damages. Notably, the ROS-inhibitor-treated group ameliorated not only oxidative injury but also the expression of cPLA2 and COX-2, indicating that ROS functions as the upstream signaling molecule in the inflammatory cascade of obese kidney fibrosis. ROS acts as a key messenger in the signaling transduction of obese kidney fibrosis, activating downstream cPLA2 and COX-2. The given antioxidant treatment ameliorates obese kidney fibrosis resulting from a combined high-fat diet and LPS&mdash, ROS could serve as a potential therapeutic target of obese kidney fibrosis with metabolic endotoxemia.

Background Aeroallergen sensitization may predict higher fractional exhaled nitric oxide (FeNO) levels. Objective We evaluate cut-off values of FeNO in asthmatic children with and without positive specific immunoglobulin E (IgE) to at least one of 5 aeroallergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae, cat, dog, and cockroach). Methods 564 patients with asthma and allergic rhinitis (AR) aged 5 to 18 years were enrolled into two groups. Sensitized group included 378 children with positive IgE to at least one of 5 inhaled allergens. Non-sensitized group included 186 children. Pulmonary function tests, FeNO, eosinophil counts, and IgE levels were examined. Patients were divided into preschool age (5~6 years old), elementary school children (7~11 years old) and adolescents (12~18 years old). Results In preschool children, FeNO≥15.5 ppb differentiates between non-sensitized and sensitized groups. (sensitivity 54.3%; specificity 87.5%; positive predictive value (PPV) 86.2%; negative predictive value (NPV) 57.1%; area under receiver operating characteristic curve (AUC) 0.72) Among elementary school children, the cut-off value of FeNO≥19.5 ppb showed sensitivity 66.4%; specificity 85.8%; PPV 90.5%; NPV 55.7%; AUC 0.81. In adolescents, FeNO≥27.5 ppb showed sensitivity 60.2%; specificity 85.4%; PPV 91.2%; NPV 46.1%; AUC 0.76. Conclusion In asthmatic children, aeroallergen sensitization appears to contribute to higher FeNO levels than those not sensitized. Cut-off values of FeNO which well discriminate asthmatic children with and without aeroallergen sensitization should be chose according to different ages.

OBJECTIVE: Most of the existing findings on the association between diabetes mellitus and colorectal cancer were generated from studies in Western societies. However, significant differences in cancer incidence and cancer-prone lifestyles are apparent between Asian and Western countries. This study aims to estimate the risks of colorectal cancer in the diabetic population in Taiwan by conducting a large-scale, controlled cohort study. METHODS: From Taiwan's Longitudinal Health Insurance Database 2005 (LHID2005), a total of 37 001 diabetic patients were identified. We also obtained data for four controls per patient, matched for sex, age and year of first entry into the LHID2005. All patients were followed up from the date of entry into the LHID2005 until they developed colorectal cancer or to the end of 2006, whichever was earlier. We used Cox's regression models to assess the risk of developing colorectal cancer, with adjustment for sex, age, comorbid disorders, and socioeconomic characteristics. RESULTS: We identified 37 001 diabetic patients and 148 004 controls. The adjusted hazard ratio for colorectal cancer in diabetes mellitus patients was 2.1 (95% confidence interval, 1.82-2.42) compared with controls. The risk was significant to both men and women. The adjusted hazard ratios for colorectal cancer were 2.03 (95% confidence interval, 1.68-2.47) in male diabetes mellitus patients and 2.17 (95% confidence interval, 1.77-2.67) in female diabetes mellitus patients. CONCLUSIONS: Our findings based on a large population-based cohort study provide evidence that diabetes mellitus may increase the risk of colorectal cancer in Asians.

Summary Background Septic acute kidney injury (AKI) is a common complication in intensive care units (ICU), it and portends a higher risk of morbidity and death than nonseptic AKI. However, its outcome and prognostic factors among elderly postoperative patients remain unknown. We aimed to determine the risk factors and predictors of mortality among postoperative elderly patients (≥ 65 years) with septic AKI requiring acute dialysis. Methods The study protocol was based on that of a clinical cohort study of renal failure patients in the database of the National Taiwan University Surgical ICU Acute Renal Failure (NSARF) Study Group. From January 2002 to July 2009, patients (aged > 18 years) with postoperative AKI requiring renal replacement therapy (RRT) were recruited for this study. Each case of septic AKI before operation was identified and patients with end-stage renal disease were excluded. Results A total of 292 postoperative patients with septic AKI requiring dialysis were identified during the study period. The mean (SD) age was 65.9 (11.9) years and 68.2% were men. Abdominal surgery was the most common type of surgery (42.8%), followed by cardiovascular (28.8%) and chest surgery (15.4%). The most common indications for RRT in this study cohort were azotemia in 223 patients (76.4%) and fluid overload in 62 patients (21.2%); 92 (31.5%) patients had one indication, 170 (58.2%) had two indications, and 30 (10.3%) had more than three indications. The elderly patients (those ≥ 65 years) had anemia, underwent abdominal surgery, and received dialysis for fluid overload more frequently than the young adults. By contrast, the young adults were more likely to present with shock requiring vasopressor use and have abnormal liver functions. In the elderly subgroup, the outcome was found to be associated with mechanical ventilator use, but not with disease severity, comorbidities, types of surgery and the indication for dialysis. Conclusions The hospital mortality of postoperative elderly patients with septic AKI was more than 60% and was not affected by age. Mechanical ventilator use was the major risk factor and prognostic factor for elderly patients in this clinical setting.

Background/Purpose Patients with end-stage renal disease (ESRD) are at particular risk for methicillin-resistant Staphylococcus aureus (MRSA) infections, especially via nasal colonization of MRSA. Surveillance cultures are recommended to identify patients colonized by MRSA. Methods Clinical data and screening cultures of S. aureus from the anterior nares of 541 patients on long-term dialysis in the hospitals were performed in March 2007. The follow-up survey was conducted 1 year later. Results A total of 32 (5.9%) of the 541 patients were positive nasal cultures for MRSA, while 89 (16.5%) were positive for methicillin-susceptible S. aureus (MSSA). In a multivariate analysis, risk factors for ESRD patients with MRSA colonization included congestive heart failure, nursing home admission, and nasogastric tube feeding in the last 3 months. Follow-up of the 32 MRSA colonized patients showed that one (3.1%) died due to MSSA and three (9.3%) died due from MRSA infection. Conclusions We found that patients with ESRD and MRSA nasal colonization were associated with a history of congestive heart failure, nursing home admission, and nasogastric tube feeding in the last 3 months.

We conducted this study to investigate whether subjects with high-normal systolic blood pressure (SBP) have an increased risk of cardiovascular disease (CVD) and/or diabetes compared to subjects with low-normal SBP, using metabolic syndrome (MetS) as a risk factor for future CVD/diabetes.The study included 6133 apparently healthy Taiwanese men aged 40-65 years. All subjects were normotensive, and none took medication for any abnormal MetS component. To avoid the effect of age on blood pressure, we stratified patients first by age then by SBP (that is, low, middle, and high SBP). We pooled all the low, middle, and high SBP groups from the different age strata to create 3 larger groups (Group 1, Group 2, and Group 3, respectively). The MetS components in subjects with the lowest SBP (Group 1) were compared with those in the other 2 groups. All of the MetS components, except for high-density lipoprotein cholesterol (HDL-C), were significantly lower in Group 1. Thus, it was not surprising that Group 2 and Group 3 had significantly higher odds ratios for abnormal body mass index, fasting plasma glucose, low-density lipoprotein-cholesterol (LDL-C), and triglycerides than Group 1 (but not for HDL-C). Specifically, Group 3 had a 1.7-fold higher odds ratio (p < 0.001) for having MetS than Group 1. Age, body mass index, fasting plasma glucose, LDL-C, and log triglycerides correlated significantly with SBP. In multivariate linear regression analysis, we found that only body mass index, fasting plasma glucose, and log triglycerides remained significantly related to SBP. Among them, body mass index had the highest β value.In conclusion, the level of SBP was highly correlated with body mass index, fasting plasma glucose, and triglycerides in subjects with normotension. Although there is not a cause-and-effect relationship, the risk of CVD and diabetes was significantly associated with an elevation of SBP, even when the SBP remained within the normal range. Further studies are needed to determine whether normotensive subjects would benefit from medical management.

Background: Elevated alanine aminotransferase (e-ALT) and abnormal liver echogenicity (ab-echo), as determined by sonography, have been linked to metabolic syndrome (MetS). However, which of these is more closely related to MetS, especially among older men, remains unknown. Methods: Data from 3065 men aged 65 years or older who were undergoing a routine health examination and who were not taking any medications for MetS were analyzed retrospectively. The patients were divided into 4 groups: group N (n = 1228; patients have normal ALT and liver echogenicity); group A (n = 110; patients have e-ALT but normal liver echogenicity); group E (n = 1381; patients have ab-echo but normal ALT); group AE (n = 346; patients have both e-ALT and ab-echo). Results: Among the 3065 subjects, 714 participants were found to have MetS (23.3%). It is not surprising that MetS components were highest in group AE. More interestingly, compared with group A, group E had higher levels of MetS components (except that high-density lipoprotein cholesterol levels were lower). Similar findings were confirmed by logistic regression. Group E had a significantly higher odds ratio of having MetS than group A (2.73; 95% CI, 1.565–4.763). Conclusions: Our data confirm that both e-ALT and ab-echo are related to a higher incidence of MetS among Taiwanese older men. Of these 2 abnormalities, ab-echo seems to be more closely related to MetS. Further studies are needed to elucidate the complex relationships between these factors in other age and ethnic groups.

Background/Purpose Aggregatibacter ( Actinobacillus ) actinomycetemcomitans , part of the normal flora of the mouth, is frequently found in human periodontal cultures and is an important pathogen causing various invasive infections, particularly infective endocarditis. In this study, we describe the clinical course and outcome of patients with A. actinomycetemcomitans infection. Methods All patients suffering invasive A. actinomycetemcomitans infections at the National Taiwan University Hospital from January 1985 to December 2004 were included in this study. Relevant data regarding clinical presentation, antimicrobial treatment and outcome of these patients were analyzed. Results During the study period, there were 11 patients with invasive A. actinomycetemcomitans infections, including eight patients with infective endocarditis, one with osteonecrosis and two with pneumonia and chest wall lesions. Among the patients with infective endocarditis, four had prosthetic valve replacement, four suffered from rheumatic heart disease and one had undergone surgical repair of ventricular septal defect. Lesions in the oral cavity were the probable portals of entry of the microorganism, and included carious teeth, periodontitis or radiotherapy of the ear-nose-throat field, and were noted in nine patients. Transthoracic echocardiography and/or transesophageal echocardiography were performed on the patients with probable infective endocarditis but growth was demonstrated in only four of these patients. Blood culture yielded A. actinomycetemcomitans after prolonged incubation. Three isolates were resistant to penicillin and two of these were also resistant to ampicillin. Conclusion The diagnosis of invasive A. actinomycetemcomitans infection was delayed due to the indolent clinical course, non-specific presentation and slow growth of the organism. Antibiotic therapy using amoxicillin/clavulanic acid, ampicillin, ampicillin/sulbactam, ceftriaxone, clindamycin, cefotaxime, or levofloxacin was successful in all patients. None of the patients demonstrated recurrence of infection 2-36 months following treatment.

The aim of this study was to evaluate the diagnostic performance of an enzyme-linked immunospot (ELISPOT) assay for interferon-γ in patients with suspected genitourinary tuberculosis (TB). A total of 30 patients with suspected genitourinary TB at the National Taiwan University Hospital, Taipei, Taiwan, were prospectively enrolled from January 2007 to December 2009, and 12 of whom had positive urine culture for Mycobacterium tuberculosis . Frequency and dysuria were the most common symptoms noted in 6 (50.0%) and 4 (33.3%) patients, respectively. Pyuria was the most common finding of urinalysis noted in 11 (91.7%) patients. Six (50.0%) patients had positive acid-fast stain in urine. Among the 30 patients, 13 patients had positive ELISPOT assay. Eleven patients with positive ELISPOT assay had culture-confirmed TB, and the remaining 2 patients without evidence of active TB had positive ELISPOT assay. The overall sensitivity, specificity, positive predictive value, and negative predictive value for genitourinary TB diagnosis by the ELISPOT assay were 91.7% (95% confidence interval [CI], 59.8–99.6%), 88.9% (95% CI, 63.9–98.1%), 84.6% (95% CI, 53.7–97.3%), and 94.1% (95% CI, 69.2–96.7%), respectively. In conclusion, ELISPOT assay can provide useful support in diagnosing genitourinary TB.

The interferon-γ enzyme-linked immunospot assay (ELISPOT) has been demonstrated to be useful in the diagnosis of active tuberculosis (TB). In this study we aimed to evaluate the diagnostic performance of the ELISPOT assay in cancer patients with suspected pulmonary TB. Eighty-one cancer patients with suspected pulmonary TB were prospectively enrolled from April 2007 to December 2008, to investigate the diagnostic sensitivity and specificity of the ELISPOT assay. Of the 38 patients with TB, 33 (86.8%) had positive ELISPOT results. Of the 43 patients without TB, the results of the ELISPOT assay were negative in 35 (81.3%) patients. The overall sensitivity was 86.8%, specificity 81.3%, positive predictive value 80.5% and negative predictive value 87.5%. No significant difference was noted for the diagnostic performance of the ELISPOT assay for diagnosing TB between solid cancer and haematological cancer patients. In addition, a quantitative study did not show that TB patients with solid cancers have a better response than haematological cancer patients as measured by spot-forming cells per 10(6) peripheral blood mononuclear cells after exposure to early secretory antigenic target 6 (ESAT-6) and culture filtrate protein 10 (CFP-10). In conclusion, the ELISPOT assay could be a useful supplementary tool for the diagnosis of pulmonary TB among cancer patients, irrespective of cancer type.

OBJECTIVES: To evaluate the diagnostic performance of procalcitonin (PCT) in elderly patients with bacterial infection in the emergency department (ED). DESIGN: Prospective. SETTING: ED of a tertiary care hospital. PARTICIPANTS: Elderly patients with systemic inflammatory response syndrome (SIRS) enrolled from September 2004 through August 2005. MEASUREMENTS: A serum sample for the measurement of PCT, two sets of blood cultures, and other cultures of relevant specimens from infection sites were collected in the ED. Two independent experts blinded to the PCT results classified the patients into bacterial infection and nonbacterial infection groups. RESULTS: Of the 262 patients with SIRS enrolled, 204 were classified as having bacterial infection and 48 as having bacteremia. PCT levels were significantly higher in patients with bacteremia than in those without. The area under the receiver operating characteristic curve for identification of bacteremia according to PCT was 0.817 for the old-old group (≥75), significantly higher than 0.639 for the young-old group (65–74); P=.02). The diagnostic sensitivity, specificity, positive predictive value, and negative predictive value of PCT for bacteremia in patients aged 75 and older were 96.0%, 68.3%, 33.8%, and 98.8%, respectively, with a PCT cutoff value of 0.38 ng/mL. CONCLUSION: PCT is sensitive for diagnosing bacteremia in elderly patients with SIRS at ED admission but is helpful in excluding bacteremia only in those aged 75 and older. PCT is not an independent predictor of local infections in these patients.

Permanent pacing is the treatment for chronotropically incompetent hearts. However, the right ventricular (RV) apical pacing-induced asynchrony, even maintaining the atrioventricular (AV) sequential activation, has depressed left ventricular contractility. Whether RV septal pacing would less compromise the electromechanical performance of the left ventricle and the chronotropic effect on myocardial contractility, is unknown.We prospectively studied 42 patients without structural heart diseases and with symptomatic bradycardia. There were 10 patients receiving atrial pacing (AAI) pacemakers, 18 patients having AV sequential pacing at RV apex (DDDapx) and 14 patients being AV sequentially paced at septum (DDDspt). Echocardiography was performed before and within 72 h after the pacemaker implantation. The ventricular mechanical performance and asynchrony was compared in conditions of programmed rates of 60, 80 and 100/min.Myocardial performance index was significantly better in DDDspt than in DDDapx patients (p=0.003). With faster programmed rate, the QRS/RR increased (p0.05) in DDDapx patients with more inter- and intraventricular asynchrony, implicating the disadvantage of prolonged depolarization time. The DDDspt group demonstrated comparable parameters of diastolic function to AAI patients and preserved mechanical performance during accelerated pacing.RV septal pacing showed the advantages of shorter depolarization time, less ventricular contractile asynchrony, better mechanical performance and preserved chronotropic response on myocardial contractility in comparison with apical pacing.

Eighty-one adult patients with Salmonella enterica serotype Choleraesuis (S. Choleraesuis) bacteraemia treated at a university hospital from 1996 to 2004 were evaluated. Multivariate analysis with a logistic regression model was used to characterize risk factors for primary bacteraemia and mycotic aneurysm and to determine the association of clinical characteristics of patients based on ciprofloxacin susceptibility of the causative organism. The incidence per 100000 discharges was 0·76 in 1996 and 3·9 in 2004. The overall rate of ciprofloxacin resistance among these isolates was 59% (87 isolates) and the annual rate increased with time from 0% prior to 2000 to 80% in 2004. Among these patients, 48 (59%) had primary bacteraemia and 13 (16%) had secondary bacteraemia with mycotic aneurysm. Seventy (86%) patients had fever at presentation, 22 (27%) developed shock during hospitalization, and eight (10%) died of S. Choleraesuis bacteraemia. Patients with immunocompromised conditions had a higher risk of developing primary bacteraemia (OR 18·442, PP=0·002) and male gender (OR 7·422, P=0·039) were associated with mycotic aneurysm. Patients with mycotic aneurysm were more frequently infected with ciprofloxacin-susceptible isolates (P=0·028) and ciprofloxacin-susceptible isolates were also more frequently associated with recurrent infection than ciprofloxacin-resistant isolates (P=0·038). The incidence of S. Choleraesuis bacteraemia has increased in the past 8 years, and this increase is associated with the upsurge of ciprofloxacin-resistant isolates.

Diabetes mellitus is associated with acute and chronic complications that cause major morbidity and significant mortality. We report a 69-year-old man with unknown diabetes, presenting vague epigastric discomfort, polyuria, polydipsia, fatigue, anorexia, weight loss over 1 week and severe chest pain for 1 day. Electrocardiogram revealed ST-segment elevation in lead V1 through V6. Blood chemistry examination revealed a creatine kinase level of 2053 U/l, creatine kinase-MB (CK-MB) level 43 U/l, a troponin I level of 23.21 ng/ml, a blood sugar level of 957 mg/dl, blood osmolality of 324 mosm/kg and no ketonemia. The patient was diagnosed as hyperosmolar hyperglycemic state accompanying acute anterior wall ST-segment elevation myocardial infarction on unknown diabetes mellitus. Aggressive therapy failed to ameliorate the patient's clinical outcome.

Hypoglycemia is a significant problem of sulfonylureas treated diabetes. Although attention has focused on its neurologic consequence, the possibility of cardiovascular side effects should also be considered. A 77-year-old man presented with hypoglycemia-induced myocardial infarction with sulfonylureas therapy. We wish to report this unusual adverse effect of sulfonylureas and provide some reference for the clinicians who treat similar cases.

An 84-year-old man presented to the emergency department with severe chest pain that had begun three hours earlier. He was a heavy smoker with a history of hypertension. On examination, his blood pressure was 120/64 mm Hg, his pulse was regular at 100 beats/min, and his respiratory rate was 20

The safety, tolerability, and efficacy data for antipsychotic drugs used in the acute phase of stroke are limited. The primary aim of this study was to examine the effectiveness and safety of typical and atypical antipsychotics on acute ischemic stroke mortality. This observational study was conducted in a retrospective cohort of patients selected from the 2010–2011 National Health Research Institute database in Taiwan. Patients were tracked for 1 month from the time of their first hospitalization for acute ischemic stroke. A nested case–control analysis was used to estimate the odds ratio (OR) of 30-day mortality associated with antipsychotic drug, adjusted for age, gender, disease severity, and comorbidities. The study cohort included 47,225 subjects with ischemic stroke, including 9445 mortality cases and 37,780 matched controls. After adjustment for the covariates, antipsychotics users before ischemic stroke are associated with a 73% decrease in the rate of mortality (OR 0.27; 95% CI 0.23–0.31). After ischemic stroke, the use of antipsychotics is associated with 87% decrease in the rate of mortality (OR 0.13; 95% CI 0.1–0.16). The users of conventional antipsychotics are associated with a 78% decrease in the rate of mortality (OR 0.22; 95% CI 0.18–0.26). The users of atypical antipsychotics are also associated with a 86% decrease in the rate of mortality (OR 0.14; 95% CI 0.12–0.17). We found that 1-month mortality among acute stroke patients treated with antipsychotics is significantly lower. The benefit on lower mortality was found not only among ischemic stroke patients who had received antipsychotics previously but also among patients who start antipsychotics after their stroke.

BACKGROUND: Although much attention has been focused on the association between chronic hyperglycemia and cerebrovascular diseases in type 2 diabetes mellitus (DM) patients, there is no data regarding the risk of ischemic stroke after a hyperosmolar hyperglycemic state (HHS) attack. The objective of this study was to investigate the risk of ischemic stroke in type 2 DM patients after an HHS attack. METHODS: From 2004 to 2008, this retrospective observational study was conducted on a large cohort of Taiwanese using Taiwan's National Health Insurance Research Database (NHIRD). We identified 19,031 type 2 DM patients who were discharged with a diagnosis of HHS and 521,229 type 2 DM patients without an HHS diagnosis. Using the propensity score generated from logistic regression models, conditional on baseline covariates, we matched 19,031 type 2 DM patients with an HHS diagnosis with the same number from the comparison cohort. The one-year cumulative rate for ischemic stroke was estimated using the Kaplan-Meier method. After adjusting covariates, Cox proportional hazard regression was used to compute the adjusted one-year rate of ischemic stroke. RESULTS: Of the patients sampled, 1,810 (9.5%) of the type 2 DM patients with HHS and 996 (5.2%) of the comparison cohort developed ischemic stroke during the one-year follow-up period. After adjusting for covariates, the adjusted HR for developing ischemic stroke during the one-year follow-up period was 1.8 (95% C.I., 1.67 to 1.95, P

Objective To evaluate the cause-effect relationships between serum levels of uric acid (UA) and metabolic syndrome (MetS) in an adolescent-male cohort that was followed for 2.7 years. Study design We enrolled male adolescents aged between 10 and 15 years at the baseline. A total of 613 subjects were divided into quartiles according to their UA levels, from UA-1 (the lowest) to UA-4 (the highest). Results After the mean follow-up period of 2.7 ± 0.97 years, 19 (3.1%) subjects developed MetS. Waist circumference (WC), systolic blood pressure, high density lipoprotein cholesterol (HDL-C), and log triglyceride levels were significantly related to baseline UA levels. Compared with the UA-1 group, subjects in the UA-4 group had significantly higher OR for abnormal WC, blood pressure, and HDL-C at the end of follow-up and had a 6.39-fold higher OR (95% CI 1.41-29.08; P 7.6 mg/dL had a 4.32 (95% CI 1.57-11.93) higher risk of developing MetS. Conclusions In this longitudinal study, we found that serum UA is correlated with future WC, systolic blood pressure, triglyceride, and HDL-C and is a risk factor for developing MetS. UA might be valuable in predicting adolescent MetS.

Background: The pathophysiology of thyroid function on lipid and glucose metabolism and blood pressure for subjects with thyroid disorder is well known; however, studies exploring the association between thyroid function and components of metabolic syndrome (MetS) in elderly subjects with subclinical thyroid dysfunction are limited. Our objectives were to investigate the prevalence of subclinical thyroid dysfunction among the elderly and its relationship with MetS in Taiwan. Methods: A total of 6,652 subjects aged 65 years or older were recruited during a routine health checkup at four MJ Health Screening Centers in Taiwan. Gender; blood pressure; body mass index; and serum levels of fasting glucose, total cholesterol (TC), high-density-lipoprotein cholesterol (HDL-C), low-density-lipoprotein cholesterol, and triglyceride were compared between subjects with subclinical hypothyroidism and hyperthyroidism. Results: The overall prevalences of the MetS, subclinical hyperthyroidism, and subclinical hypothyroidism were 30.4%, 6.0%, and 2.0%, respectively. The prevalence of subclinical thyroid dysfunction was significantly higher among women as compared with men (9.9% vs. 6.3%, respectively; p
