Abstract Background Due to cardiotoxicity concerns, the concurrent use of epirubicin and trastuzumab has not been fully studied. This study aimed to examine the cardiotoxicity and pathological complete response (pCR) rate associated with the concurrent regimens in patients with human epidermal growth factor receptor 2 (HER2)‐positive early breast cancer (EBC). Methods We conducted a systematic search for relevant literature in the NCBI/PubMed, the Cochrane database, and international conference abstracts for phase II or III randomized controlled trials between January 1, 2000, and February 28, 2021, focusing on the concurrent regimens in patients with HER2‐positive EBC. To compare the risk of cardiotoxicity and the odds of the pCR rate, we performed linear meta‐regression analyses to investigate the effects of multiple covariates. Results We analyzed 7 neoadjuvant trials involving the concurrent use of epirubicin and trastuzumab with 1797 patients. The median cumulative dose of epirubicin used was 300 mg/m2, with a total of 96 reported adverse cardiac events. The concurrent regimens did not result in a significant increase in cardiotoxicity compared to nonconcurrent regimens (risk ratio [RR] = 1.18, 95% confidence interval [CI] = 0.68–2.05). Compared with nonconcurrent or non‐anthracycline‐containing regimens, concurrent regimens were associated with a significant increase in the pCR rate (odds ratio = 1.48, 95% CI = 1.04–2.12). The linear fixed‐effects meta‐regression analysis indicated that in trials including more patients with hormone receptor‐positive EBC, the RR of cardiotoxicity significantly increased with concurrent regimens, and the pCR rate became less significant. Conclusions The combination of trastuzumab and a low dose of epirubicin positively impacted the pCR rate without a significant increase in cardiotoxicity. We recommend exploring concurrent regimens for HR‐negative, HER2‐positive tumors to enhance pCR rates, with caution advised for HR‐positive tumors due to potential cardiotoxicity.

Abstract Background Immune checkpoint inhibitors have revolutionized the treatment of malignancies. However, disproportionate enrollment among races and ethnicities places the generalizability of global trial results in doubt. Methods In this systematic review, phase 3 randomized controlled trials investigating pembrolizumab in advanced cancers and providing subgroup analyses of Asian and non‐Asian participants were included. The primary and secondary effect measures were the mean differences (MDs) in the natural logarithms of the hazard ratios (HRs) for overall survival (OS) and progression‐free survival (PFS) between these two subgroups, respectively. We used random‐effects meta‐analysis to calculate the pooled ratios of HRs (i.e., exp(MD)) and implemented a meta‐regression analysis to identify significant covariates. Results A total of 17 and 11 trials were included in the meta‐analyses of OS and PFS, respectively. These trials included 2732 (25.49%) Asian and 7000 (65.32%) non‐Asian participants in the OS analysis and 1438 (22.5%) Asian and 4129 (64.61%) non‐Asian participants in the PFS analysis. The pooled ratio of HRs for OS was 0.87 (95% CI: 0.76–0.99; p = 0.0391), favoring Asian participants, but no significant difference was found in PFS (pooled ratio of HRs: 0.93; 95% CI: 0.82–1.07; p = 0.2391). Both linear meta‐regression analyses revealed an open‐label design as a crucial covariate, which indicated more benefits for non‐Asian participants. Conclusions Compared with non‐Asian patients, Asian patients with advanced cancers may derive superior OS benefits from pembrolizumab. Although the results warrant further exploration, this meta‐analysis provides insight into clinical research design.

Background: The Dispositional Flow Scale-2 (DFS-2) is an instrument for measuring the flow experiences of the general population while participating in daily activities. This study aimed to examine the equivalence in the measurement structure of Traditional Chinese DFS-2 (TCDFS-2) between the schizophrenic patients and healthy subjects. Methods: We recruited 100 adults with schizophrenia or schizoaffective disorder from the psychiatric clinics or the centers for daycare or rehabilitation and 104 healthy adults. Each participant finished the TCDFS-2 by recalling the most important and meaningful daily activity. Results: We conducted two two-group confirmatory factor analyses (CFA) with the healthy subjects and schizophrenic patients as the reference group respectively in LISREL. When the healthy subjects as the reference standard, 43 items of the TCDFS-2 were added to this constrained two-group CFA model for the schizophrenic patients, but the cross-group equivalence was still unsatisfactory. By contrast, when the schizophrenic patients as the reference standard, only 6 items were added for the healthy subjects, and the cross-group equivalence was barely acceptable. Conclusion: Thus, the measurement structures of the TCDFS-2 were quite different between the schizophrenic patients and healthy subjects. The flow states experienced by the schizophrenic patients might not entirely be the same as those of the healthy subjects.

Background: Patients with childhood cancer are at increased risk for the development of second cancers. Methods: A national multicenter survey of second cancers conducted by the Taiwan Pediatric Oncology Group retrieved retrospective data from the database at the Children Cancer Foundation in Taiwan beginning in 1995. The characteristics of second cancers and associations of patient demographic and clinical characteristics with time to death due to a second cancer were analyzed. Results: We examined the records of 8782 patients with a primary cancer diagnosed between January 1, 1995 and December 31, 2013, and a total of 99 patients with a second cancer were identified. The most common type of second cancer was acute myeloid leukemia (n = 35), followed by acute lymphoblastic leukemia (n = 15), central nervous system (CNS) tumors (n = 15), and sarcomas (n = 10). Secondary hematological malignancies occurred earlier than other secondary cancers. The frequencies of second CNS tumors and second bone cancers and sarcomas were notably increased when prior radiation doses increased from zero, low dose to high dose. The overall 5-year survival of patients with a second cancer was poor (33.7%). Multivariate survival analysis revealed that the year of primary diagnosis ≤2002, secondary hematological malignancies, and age at second cancer diagnosis ≤9.3 years or >26.8 years increased the risk of death following second cancer. Conclusion: Children who develop a second cancer have an unfavorable outcome. Early detection and improved treatment for second cancers are needed.

Background: This meta-analysis aimed to test the hypothesis that the HER2-positive metastatic breast cancer (mBC) patients treated with anti-HER2 antibodies in trial intervention arms have a greater prolongation of overall survival (OS) than of progression-free survival (PFS) and this extra-prolongation of median survival time in OS relates specifically to the anti-HER2 antibody. Methods: The NCBI/Pubmed and Cochrane databases were searched systematically for HER2-positive or mBC trials published in English during January 1999–November 2017. Treatment arms with shorter PFS were considered as the “control” arm, whereas those with longer PFS as the “test” arm. The between-treatment drug differences were grouped into nine categories. Groups with or without anti-HER2 antibodies were pooled respectively for comparisons. The interrelationships between PFS and OS hazard ratios (HRs) and median survival time differences were investigated by conducting fixed-effects and mixed-effects linear meta-regression analyses. Results: Twenty-eight trials (10,928 patients) from 438 articles were collected, and four with missing data were excluded in meta-regression analysis. Overall median PFS (HR = 0.73, 95% CI: 0.68–0.78) and median OS (HR = 0.82, 95% CI: 0.77–0.87) weakly favored the longer PFS arm with a weak correlation between the PFS and OS HRs. However, the between-treatment drug difference was anti-HER2 antibody, the absolute increment in median OS time was double that of median PFS time (p

The aim of this study was to update the information on internationally acceptable standards and clinical practice recommendations for the management of patients with primary aldosteronism (PA). The Taiwan Society of Aldosteronism (TSA) Task Force acknowledged the novel issues of PA and reached a group consensus on PA in Taiwan by collecting the best available evidence and conducting one group meeting, several conference calls, and multiple e-mail communications. Unilateral adrenalectomy is the preferred treatment for patients with aldosterone-producing adenoma (APA). For medical treatment with mineralocorticoid receptor antagonists (MRAs), spironolactone is the first-line treatment, and eplerenone is a reasonable alternative in PA patients intolerant or contraindicated to spironolactone. The dose of MRAs can be titrated according to plasma renin activity (PRA). For screening PA-related comorbidities, we suggest albuminuria to predict a post-treatment decline in renal function, echocardiography as cardiac evaluation, bone mineral density scan for osteoporosis, and obstructive sleep apnea. In tissue and genetic surveys, we suggest immunohistochemical staining and somatic mutation screening for post-operative adrenal specimens in APA patients. With this consensus, we hope to update the information on PA for clinical physicians to facilitate better identification, management and treatment of patients with PA.

Background/Purpose: Even with the increasing recognition of primary aldosteronism (PA) as a cause of refractory hypertension and an issue of public health, the consensus of its optimal surgical or medical treatment in Taiwan has not been reached. Our objective was to develop a clinical practice guideline that is feasible for real-world management of PA patients in Taiwan. Methods: The Taiwan Society of Aldosteronism (TSA) Task Force recognized the above-mentioned issues and reached this Taiwan PA consensus at its inaugural meeting, in order to provide updated information of internationally acceptable standards, and also to incorporate our local disease characteristics and constraints into PA management. Results: In patients with lateralized PA, including aldosterone producing adenoma (APA), laparoscopic adrenalectomy is the ‘gold standard’ of treatment. Mini-laparoscopic and laparoendoscopic single-site approaches are feasible only in highly experienced surgeons. Patients with bilateral adrenal hyperplasia or those not suitable for surgery should be treated by mineralocorticoid receptor antagonists. The outcome data of PA patient management from the literature, especially from PA patients in Taiwan, are reviewed. Mental health screening is helpful in early detection and management of psychopathology among PA patients. Conclusion: We hope this consensus will provide a guideline to help medical professionals to manage PA patients in Taiwan to achieve a better quality of care.

Background/Purpose: Even though the increasing clinical recognition of primary aldosteronism (PA) as a public health issue, its heightened risk profiles and the availability of targeted surgical/medical treatment being more understood, consensus in its diagnosis and management based on medical evidence, while recognizing the constraints of our real-world clinical practice in Taiwan, has not been reached. Methods: The Taiwan Society of Aldosteronism (TSA) Task Force acknowledges the above-mentioned issues and reached this Taiwan PA consensus at its inaugural meeting, in order to provide updated information of internationally acceptable standards, and also to incorporate our local disease characteristics into the management of PA. Results: When there is suspicion of PA, a plasma aldosterone to renin ratio (ARR) should be obtained initially. Patients with abnormal ARR will undergo confirmatory laboratory and image tests. Subtype classification with adrenal venous sampling (AVS) or NP-59 nuclear imaging, if AVS not available, to lateralize PA is recommended when patients are considered for adrenalectomy. The strengths and weaknesses of the currently available identification methods are discussed, focusing especially on result interpretation. Conclusion: With this consensus we hope to raise more awareness of PA among medical professionals and hypertensive patients in Taiwan, and to facilitate reconciliation of better detection, identification and treatment of patients with PA.

EQ-5D (EuroQol-5 dimensions) is a preference-based measure of health, which is widely used in cost–utility analyses. It has been suggested that each country should develop its own value set. We therefore sought to develop the quality weights of the EQ-5D health states with the time trade-off (TTO) method in Taiwan. Methods: A total of 745 respondents consisting of employees and volunteers in 17 different hospitals were recruited and interviewed. Each of them valued 13 of 73 EQ-5D health states using the TTO method. Based on the three exclusion criteria for valuation data, only 456 (61.21%) respondents were considered eligible for data analysis. The quality weights for all EQ-5D health states were modeled by generalized estimating equations (GEEs). Results: Over half of the responses were given negative values, and the medical personnel seemed to have a significantly higher TTO value (+0.1) than others after controlling for other predictors. The N3 model (level 3 occurred within at least 1 dimension) yielded an acceptable fit for the observed OTT data [mean absolute error (MAE) = 0.056, R2 = 0.35]. The magnitude of mean absolute differences (MADs) between Taiwan data and those from the UK, Japan, and South Korea ranged from 0.146 to 0.592, but the rank correlation coefficients were all above 0.811. Conclusion: This study reaffirms the differences in health-related preference values across countries. The high proportion of negative values might indicate that we have also partially measured the intensity of fear in addition to the utility of different health states.

The effectiveness of education programs for pediatric patients receiving oral antibiotic suspension was unclear. Methods: When pediatric patients were prescribed antibiotics in powder form for suspension at the outpatient clinic of a university hospital, the responsible 150 caregivers were consecutively allocated into three education programs: Group 1 subjects read the package insert; Group 2 read a photograph-designed educational sheet; and Group 3 received a face-to-face medication education from a pharmacist with the photograph-designed educational sheet. The effectiveness of the three education programs for pediatric patients' caregivers was evaluated using a questionnaire comprised of 12 questions. Results: The proportions of the caregivers in Groups 1, 2 and 3 who answered the questionnaire perfectly with 100% accuracy were 2%, 14% and 74%, respectively (p

In addition to diabetic retinopathy, diabetes also causes early retinal neurodegeneration and other eye problems, which cause various types of visual deficits. This study used a computer-based visual test (Macular Multi-Function Assessment (MMFA)) to assess contrast-dependent macular visual function in patients with type 2 diabetes to collect more visual information than possible with only the visual acuity test. Because the MMFA is a newly developed test, this study first compared the agreement and discriminative ability of the MMFA and the Early Treatment Diabetic Retinopathy Study (ETDRS) contrast acuity charts. Then symbol discrimination performances of diabetic patients and controls were evaluated at 4 contrast levels using the MMFA. Seventy-seven patients and 45 controls participated. The agreement between MMFA and ETDRS scores was examined by fitting three-level linear mixed-effect models to estimate the intraclass correlation coefficients (ICCs). The estimated areas under the receiver operating characteristic (ROC) curve were used to compare the discriminative ability of diseased versus non-diseased participants between the two tests. The MMFA scores of patients and controls were compared with multiple linear regression analysis after adjusting the effects of age, sex, hypertension and cataract. Results showed that the scores of the MMFA and ETDRS tests displayed high levels of agreement and acceptable and similar discriminative ability. The MMFA performance was correlated with the severity of diabetic retinopathy. Most of the MMFA scores differed significantly between the diabetic patients and controls. In the low contrast condition, the MMFA scores were significantly lower for 006Eon-DR patients than for controls. The potential utility of the MMFA as an easy screening tool for contrast-dependent visual function and for detecting early functional visual change in patients with type 2 diabetes is discussed.

Immune thrombocytopenia (ITP) is a heterogeneous autoimmune disorder with diverse response rates to treatments that include corticosteroids, intravenous immunoglobulins (IVIG), and splenectomy. The predisposing causes of this autoimmune disorder, one of which is immunogenetic susceptibility, have not been fully determined. We investigated whether clinical features and human leukocyte antigen (HLA) genotypes influence the occurrence, treatment response, and disease duration of childhood ITP in Taiwan. Methods: We performed HLA genotyping of 70 Taiwanese children with ITP and of 70 healthy controls and compared the data. Demographic data were also collected and evaluated. Results: The frequencies of heterozygous HLA-A11 and the HLA-Cw1 allele were both significantly decreased in the ITP group (p = 0.0160 and p = 0.0089, respectively), whereas the frequency of heterozygous HLA-DQ5 was significantly increased in the ITP group (p = 0.0057). Patients with HLA-DRB1*11 or -DRB1*15 were more likely to respond poorly to corticosteroids than IVIG (p = 0.0446 and p = 0.0008, respectively). In addition, we observed a positive association between HLA-A11 homozygosity and the development of persistent or chronic ITP [odds ratio (OR) = 6.3165, p = 0.0479]. The presence of HLA-DRB1*08 was, however, negatively correlated with the development of persistent or chronic ITP (OR = 0.1729, p = 0.0657). Children with antecedent of preceding illness (API) and with a younger age of onset were more likely to experience a better treatment response and shorter course of ITP. Conclusion: We suggest that API, age of onset, and particular HLA class I and class II alleles, may be involved in and influence the occurrence and disease duration of childhood ITP, as well as responses to different therapeutic approaches.

Background: Epidermal growth factor receptor antagonists, such as gefitinib, erlotinib, and cetuximab, have been used in treating carcinomas. The efficacies have been proposed to correlate with skin reactions, but the most important predictive indicator is still unknown. Our aim was to investigate the types of skin toxicities and to analyze the major therapeutic predictive indicators in Taiwan. Methods: A retrospective analysis was used to study 68 patients with advanced non-small-cell lung cancer receiving gefitinib. Results: Acneiform eruption (41.2%), xerosis (38.2%), pruritus (26.5%), and paronychia (16.2%) composed most of the skin reactions. The univariate analysis revealed paronychia as the most substantial survival predictive indicator (p=0.0427). In the multivariate analysis, older patients with paronychia had better prognosis (p=0.0050). Women tended to develop paronychia (p=0.1098). Xerosis positively correlated with paronychia (p=0.0082). Conclusion: Paronychia is the most indicative survival predictive factor among the skin manifestations, and it correlates with age, gender, and xerosis. Elucidation of the relationship between cutaneous reactions can provide information on the epidermal growth factor receptor signaling mechanism of skin.

Whether the length of stent affects stent-related symptoms after urological procedures remains controversial. We aimed to evaluate the predictive factors for stent-related urinary tract symptoms after uncomplicated ureteroscopic lithotripsy (URSL). Methods: We prospectively recruited a total of 59 patients who underwent URSL and 6-Fr double-J ureteral stent placement. The demographic and perioperative data and stent characteristics, including the length (22, 24 or 26 cm), position of proximal end (upper calyx or pelvis), position of distal end (crossing midline or not), and configurations of both ends (complete or incomplete curl) were recorded. All patients completed a self-administered questionnaire to evaluate the stent-related urinary symptoms, bladder pain, flank pain and hematuria 1 week after the procedure. All variables were analyzed by a proportional odds logistic regression model. Results: Twenty-two male (37.3%) and 37 (62.7%) female patients were enrolled in this study. Their mean age was 53.7 ± 12.9 years. The mean body height was 161.9 ± 7.9 cm (range, 145.9–178 cm). In multivariate analysis, the 26-cm stent was independently associated with the severity of frequency, urgency, and nocturia symptoms. Crossing the midline of the distal end was significantly associated with urge incontinence. The 24-cm and 26-cm stents were both very strongly associated with the severity of hematuria. Crossing the midline of the distal end was significantly associated with bladder pain. Conclusion: The length of stent and crossing the midline of the distal end were significantly associated with stent-related symptoms after URSL. Selection of the proper length of double-J stent is the most important factor in minimizing stent-related symptoms.

Hypersensitivity reactions during oxaliplatin infusion are a major problem associated with its use. In this study, we investigated the characteristics and risk factors of these events. Methods: All patients who had received oxaliplatin in outpatient settings from January 2006 to March 2007 in a medical center were enrolled in this retrospective study. All the oxaliplatin infusions were reviewed. Manifestations of hypersensitivity reactions and clinicopathological variables were collected from medical records. Results: Three hundred and eighty-three patients with 3648 oxaliplatin infusions were reviewed. Forty-seven patients (12.7%) developed hypersensitivity reactions, which occurred after a median of 10 infusions. The median time of onset from start of infusion was 40 minutes. Most presentations (90.7%) were mild to moderate, but rechallenge with oxaliplatin led to a high chance of further reactions (71.4%). Cutaneous symptoms were the most prevalent manifestation, followed by respiratory symptoms. With each repeated infusion, the incidence of hypersensitivity reactions increased. Higher oxaliplatin dose per infusion was an independent risk factor for such reactions. Conclusion: Patients treated with oxaliplatin for an extended period have a greater risk of oxaliplatin-related hypersensitivity reactions.

Chinese are more sensitive to β-blockers than Caucasians. However, data regarding β-blocker therapy in heart failure (HF) patients in Taiwan are lacking. We aimed to evaluate the improvement of left ventricular function and the potential predictors of response to β-blocker therapy in Taiwanese HF patients. Methods: We enrolled 34 HF patients with baseline left ventricular ejection fraction (LVEF) ≤ 40%. Beta-blockers were titrated up to the maximum tolerable dose. LVEF prior to β-blocker usage and at the stable dose were obtained. We also sequenced the entire gene encoding β1-adrenoceptor to assess the relationships between LVEF improvement and gene polymorphisms. Results: Beta-blocker therapy (25 ±22 months) with a mean stable dose of 12 ± 8 mg carvedilol/day significantly improved LVEF (from 28 ±8% to 40 ± 15%, p< 0.001). Stepwise multiple linear regression analysis identified dilated cardiomyopathy (β= 18.32, p = 0.0004), baseline LVEF (β=−0.85, p = 0.0020), use of amiodarone (β = −22.58, p = 0.0034) and square of digoxin dose (β=−314.25, p = 0.0059) at stable β-blocker dose as independent predictors of LVEF improvement, where β is the estimated regression coefficient. We did not find any novel variant of β1-adrenoceptor gene other than those previously reported at codons 49 and 389, with the allele distributions similar to those found in Caucasians, and these polymorphisms did not imply therapeutic response to β-blocker. Conclusion: We demonstrated the therapeutic effects of β-blockers in Taiwanese HF patients with a dose lower than what has been reported in Western people. Moreover, patients with the etiology of dilated cardiomyopathy or lower baseline LVEF predicted a greater LVEF improvement. The β1-adrenoceptor gene polymorphisms were not responsible for the difference in sensitivity to β-blockers in this Taiwanese population.

Milk products are good sources of calcium that may reduce bone resorption and help prevent bone loss as well as promote bone remodeling and increase bone formation. Kefir is a product made by kefir grains that degrade milk proteins into various peptides with health-promoting effects, including antithrombotic, antimicrobial and calcium-absorption enhancing bioactivities. In a controlled, parallel, double-blind intervention study over 6 months, we investigated the effects of kefir-fermented milk (1,600 mg) supplemented with calcium bicarbonate (CaCO3, 1,500 mg) and bone metabolism in 40 osteoporosis patients, and compared them with CaCO3 alone without kefir supplements. Bone turnover markers were measured in fasting blood samples collected before therapy and at 1, 3, and 6 months. Bone mineral density (BMD) values at the spine, total hip, and hip femoral neck were assessed by dual-energy x-ray absorptiometry (DXA) at baseline and at 6 months. Among patients treated with kefir-fermented milk, the relationships between baseline turnover and 6 months changes in DXA-determined BMD were significantly improved. The serum β C-terminal telopeptide of type I collagen (β-CTX) in those with T-scores > -1 patients significantly decreased after three months treatment. The formation marker serum osteocalcin (OC) turned from negative to positive after 6 months, representing the effect of kefir treatment. Serum parathyroid hormone (PTH) increased significantly after treatment with kefir, but decreased significantly in the control group. PTH may promote bone remodeling after treatment with kefir for 6 months. In this pilot study, we concluded that kefir-fermented milk therapy was associated with short-term changes in turnover and greater 6-month increases in hip BMD among osteoporotic patients.ClinicalTrials.gov NCT02361372.

Inpatient suicide rates are seldom reported using age-standardized methods. This study aimed to estimate the standardized suicide rate in a general hospital. A total of 27 suicidal patients were identified by the adverse event reports during hospitalization from 1995 to 2004. Standardized suicide mortality ratios (SMR) were examined using the Poisson regression model. The SMR of inpatient suicide was 8.25 (95% CI = 5.67-12.06). Hospital suicide rates were considerably higher than the corresponding general population rates for all age groups and were particularly high in age categories of 25-29, 30-34, 40-44, and 55-59 years after controlling for sex and calendar year. Hospitalized patients had an eight times higher risk of suicide mortality than that of the general population. While the elderly are at increased risk for suicide in the general population, young- and middle-aged patients are the age group at risk for suicide mortality during hospitalization.

BACKGROUND: Infantile hepatitis B after neonatal immunoprophylaxis is a rare yet distinct disease. This study aimed to analyze the long-term outcomes and risk factors in immunized infants with hepatitis B. METHODS: The clinical parameters and outcomes of 41 infants born after universal immunization, and admitted for HBV-positive hepatitis were studied. All patients were followed for at least 6 months (median = 4.4 years, range 0.6-18.1 years). Patient survival, changes of HBsAg and HBeAg status, and complications were analyzed. RESULTS: Among the 41 cases (32 males, 9 females), 21 presented with fulminant hepatitis (FH), and 20 with non-fulminant hepatitis (NFH). Ninety-five percent (36/38) of the mothers were positive for hepatitis B surface antigen (HBsAg). Multivariate analyses revealed younger age of onset (age

BACKGROUND: Uremic pruritus is a common and intractable symptom in patients on chronic hemodialysis, but factors associated with the severity of pruritus remain unclear. This study aimed to explore the associations of metabolic factors and dialysis adequacy with the aggravation of pruritus. METHODS: We conducted a 5-year prospective cohort study on patients with maintenance hemodialysis. A visual analogue scale (VAS) was used to assess the intensity of pruritus. Patient demographic and clinical characteristics, laboratory parameters, dialysis adequacy (assessed by Kt/V), and pruritus intensity were recorded at baseline and follow-up. Change score analysis of the difference score of VAS between baseline and follow-up was performed using multiple linear regression models. The optimal threshold of Kt/V, which is associated with the aggravation of uremic pruritus, was determined by generalized additive models and receiver operating characteristic analysis. RESULTS: A total of 111 patients completed the study. Linear regression analysis showed that lower Kt/V and use of low-flux dialyzer were significantly associated with the aggravation of pruritus after adjusting for the baseline pruritus intensity and a variety of confounding factors. The optimal threshold value of Kt/V for pruritus was 1.5 suggested by both generalized additive models and receiver operating characteristic analysis. CONCLUSIONS: Hemodialysis with the target of Kt/V ≥1.5 and use of high-flux dialyzer may reduce the intensity of pruritus in patients on chronic hemodialysis. Further clinical trials are required to determine the optimal dialysis dose and regimen for uremic pruritus.

BACKGROUND: Effects of long-term glucose load on peritoneal dialysis (PD) patient safety and outcomes have seldom been reported. This study demonstrates the influence of long-term glucose load on patient and technique survival. METHODS: We surveyed 173 incident PD patients. Long-term glucose load was evaluated by calculating the average dialysate glucose concentration since initiation of PD. Risk factors were assessed by fitting Cox's models with repeatedly measured time-dependent covariates. RESULTS: We noted that older age, higher glucose concentration, and lower residual renal function (RRF) were significantly associated with a worse patient survival. We found that female gender, absence of diabetes, lower glucose concentration, use of icodextrin, higher serum high density lipoprotein cholesterol, and higher RRF were significantly associated with a better technique survival. CONCLUSIONS: Long-term glucose load predicted mortality and technique failure in chronic PD patients. These findings emphasize the importance of minimizing glucose load in PD patients.

AIMS: Preoperative proteinuria is associated with post-operative acute kidney injury (AKI), but whether it is also associated with increased long-term mortality and end-stage renal disease (ESRD) is unknown. METHODS AND RESULTS: We studied 925 consecutive patients undergoing CABG. Demographic and clinical data were collected prospectively, and patients were followed for a median of 4.71 years after surgery. Proteinuria, according to dipstick tests, was defined as mild (trace to 1+) or heavy (2+ to 4+) according to the results of the dipstick test. A total of 276 (29.8%) patients had mild proteinuria before surgery and 119 (12.9%) patients had heavy proteinuria. During the follow-up, the Cox proportional hazards model demonstrated that heavy proteinuria (hazard ratio [HR], 27.17) was an independent predictor of long-term ESRD. There was a progressive increased risk for mild proteinuria ([HR], 1.88) and heavy proteinuria ([HR], 2.28) to predict all-cause mortality compared to no proteinuria. Mild ([HR], 2.57) and heavy proteinuria ([HR], 2.70) exhibited a stepwise increased ratio compared to patients without proteinuria for long-term composite catastrophic outcomes (mortality and ESRD), which were independent of the baseline GFR and postoperative acute kidney injury (AKI). CONCLUSION: Our study demonstrated that proteinuria is a powerful independent risk factor of long-term all-cause mortality and ESRD after CABG in addition to preoperative GFR and postoperative AKI. Our study demonstrated that proteinuria should be integrated into clinical risk prediction models for long-term outcomes after CABG. These results provide a high priority for future renal protective strategies and methods for post-operative CABG patients.

BACKGROUND: The impact of diuretic usage and dosage on the mortality of critically ill patients with acute kidney injury is still unclear. METHODS AND RESULTS: In this prospective, multicenter, observational study, 572 patients with postsurgical acute kidney injury receiving hemodialysis were recruited and followed daily. Thirty-day postdialysis mortality was analyzed using Cox's proportional hazards model with time-dependent covariates. The mean age of the 572 patients was 60.8±16.6 years. Patients with lower serum creatinine (p = 0.031) and blood lactate (p = 0.033) at ICU admission, lower predialysis urine output (p = 0.001) and PaO(2)/FiO(2) (p = 0.039), as well as diabetes (p = 0.037) and heart failure (p = 0.049) were more likely to receive diuretics. A total of 280 (49.0%) patients died within 30 days after acute dialysis initiation. The analysis of 30-day postdialysis mortality by fitting propensity score-adjusted Cox's proportional hazards models with time-dependent covariates showed that higher 3-day accumulated diuretic doses after dialysis initiation (HR = 1.449, p = 0.021) could increase the hazard rate of death. Moreover, higher time-varying 3-day accumulative diuretic doses were associated with hypotension (p

AbstractThe present study sought to propose Ganoderma guixiense sp. nov. as a new species based on phenotypic and genotypic evidence. Phylogenetic analyses were carried out based on the internal transcribed spacer (ITS), the large subunit of nuclear ribosomal RNA gene (nLSU), and the second subunit of RNA polymerase II (RPB2) sequence data. G. guixiense has been characterized by pileate basidiomata, long stipe, in addition to reddish-black zonate pileal surface. Basidiospores are broadly ellipsoid with one end tapering at maturity, and measuring 9–12.8 × 6.5–9.3 μm. Basidia are oval to subglobose. This study marks the first exploration of the biological characteristics of G. guixiense. The result indicated that the optimal medium of mycelial growth was observed on malt extract agar (MEA) and yeast extract peptone dextrose agar (YPD) while the optimal temperature was found to be 25–30 °C with pH range of 6–7.
