    Abstract: Over 30% of cancer survivors experience chronic fatigue. An alteration in energy metabolism is one of the hypothesized mechanisms for cancer-related fatigue (CRF). No studies have evaluated for changes in metabolic profiles in cancer survivors with CRF. The purpose of this pilot study was to evaluate for differences in metabolic profiles between fatigued and non-fatigued survivors of colorectal cancer (CRC). Methods: Survivors were recruited from the surgical outpatient department and the oncology clinic of a medical center in northern Taiwan. Fatigue was assessed using the Fatigue Symptom Inventory. Fasting blood samples were collected on the day the fatigue questionnaire was completed. Metabolomic profile analysis was performed using non-targeted, liquid chromatography/time-of-flight mass spectrometry. Fold change analyses, t-tests, and pathway analyses were performed to identify differences in metabolomic profiles between the fatigued and non-fatigued survivors. Results: Of the 56 CRC survivors in this study, 28.6% (n = 16) were in the fatigue group. Statistically significant differences in carnitine, L-norleucine, pyroglutamic acid, pyrrolidonecarboxylic acid, spermine, hydroxyoctanoic acid, and paraxanthine were found between the two fatigue groups. In addition, two pathways were enriched for these metabolites (i.e., glutathione metabolism, D-glutamine and D-glutamate metabolism). Conclusions: Findings from this pilot study provide preliminary evidence that two pathways that are involved with the regulation of ATP production and cellular energy (i.e., glutathione metabolism, D-glutamine and D-glutamate metabolism) are associated with fatigue in CRC survivors. If these findings are confirmed, they may provide new therapeutic targets to decrease fatigue in cancer survivors.

    Abstract: Objective: Bipolar disorder is a recurrent disorder for the vast majority of patients, and hospitalization is normally used to control severe symptoms. The goals of treating bipolar disorder include symptomatic remission, full return of psychosocial functioning, and prevention of relapses/recurrences. Rehospitalization, however, becomes necessary with the relapse/recurrence of severe symptoms. The purpose of the present study was therefore to investigate the risk factors affecting the time to rehospitalization. Method: Rehospitalization status was monitored for all patients with bipolar I disorder discharged from Kai-Suan Psychiatric Hospital between 1 January 2002 and 31 December 2004. Patients were followed up with respect to rehospitalization until 31 December 2005. The Kaplan–Meier method was used to calculate the mean time to rehospitalization within 1 year after discharge. Risk factors associated with rehospitalization were examined using Cox proportional hazards regression model. Results: Four hundred and twenty patients were recruited for the study. Two hundred and eleven patients (50.2%) were readmitted, and the mean time to rehospitalization was 231 days (SD = 7). Bipolar depression at index hospitalization, age at onset, and the number of previous hospitalizations were found to be predictors for time to rehospitalization. Conclusion: Bipolar depression at index hospitalization, the earlier the onset of an affective episode, and a higher number of previous hospitalizations were associated with a shorter time to rehospitalization. Further studies in this field should test risk factors in a prospective study and be conducted in various mental health systems.

    Abstract: Direct oral anticoagulant (DOAC)-associated intracerebral hemorrhage (ICH) is a catastrophic complication. The aim of this study was to investigate the association between computed tomography (CT)-based cerebrovascular small vessel disease (SVD) burden and DOAC-ICH as well as the DOAC concentration upon hospital admission and ICH outcome. Patients and methods: The study included two cohorts: (1) DOAC-ICH: patients who suffered from DOAC-ICH and underwent drug level measurements upon admission; (2) DOAC-non-ICH: stable DOAC users who underwent head CT without ICH during treatment. We categorized the DOAC levels of the DOAC-ICH patients as low ( 〈 50 ng/mL), medium (50–300 ng/mL), and high ( 〉 300 ng/mL). The CT-based SVD burden (including white matter lesions [WML], lacunes, and cerebral atrophy) was evaluated, and SVD scores (range, 0–3) were used to evaluate SVD severity. Results: A total of 43 DOAC-ICH patients and 177 DOAC-non-ICH patients were enrolled. DOAC-ICH patients were more likely to have WML, lacunes, or cerebral atrophy compared to DOAC-non-ICH patients. After adjustment, the SVD burden was associated with DOAC-ICH, with a higher risk of more severe SVD (SVD score of 2; odds ratio [OR], 10.3 [3.17, 33.3] ; score of 3; OR, 16.8 [4.50, 62.6]). The proportions of patients with high, medium, and low drug levels in the DOAC-ICH group were 16.3%, 55.8%, and 27.9%, respectively. Additionally, the high-level group displayed a larger hematoma size and had worse functional outcomes at 3 months than the other two groups. Discussion and conclusion: The severity of SVD burden was associated with DOAC-ICH. Furthermore, high DOAC levels in ICH were associated with unfavorable clinical outcomes. To address the potential selection bias from these two cohorts, a prospective study to investigate the co-contribution of drug levels and SVD to DOAC-ICH is essential.

    Abstract: Aripiprazole has been reported to worsen psychotic symptoms when switching from other antipsychotics, possibly due to dopamine supersensitivity psychosis. Objective: This study aimed to explore the predictors and possible underlying mechanisms of aripiprazole-related psychotic exacerbation. Methods: We conducted an 8-week, open-label, randomized controlled study from October 2007 to September 2009, assigning patients with a primary diagnosis of schizophrenia or schizoaffective disorder to switch from other antipsychotics to aripiprazole with 2-week dual administration, and then to taper off the original agents in fast (n = 38, within 1 week) or slow (n = 41, within 4 weeks) strategies. Positive and Negative Syndrome Scale (PANSS) was examined at day 0, 7, 14, 28, 56. Aripiprazole-related exacerbation (ARE) was defined positive as a 2-point increase in delusion/hallucination dimension score within 28 days compared with baseline. Baseline demographic, clinical and intervention-related variables were compared between the ARE+ and ARE- groups. Results: Of the 79 randomized patients, 21 fulfilled the criteria of ARE+ , and 46 were classified as ARE-. Fourteen patients in the ARE+ group had worsening psychotic symptoms in the first and second weeks. Compared with the ARE- group, the ARE+ group had a higher baseline chlorpromazine equivalent dose (405.8 ± 225.8 mg vs 268.1 ± 165.4 mg, p = 0.007) and was associated with prescription of first-generation antipsychotics ( p = 0.038). Conclusions: A higher dose of original antipsychotics and prescription of first-generation antipsychotics may be associated with a higher risk of ARE. The underlying mechanism might be covert dopamine supersensitivity psychosis. These findings may help to identify high-risk patients and guide appropriate treatment strategies.

    Abstract: To investigate factors associated with major adverse cardiovascular events (MACEs) in patients with rheumatoid arthritis (RA). Methods: We conducted a nationwide, population-based, case-control study using Taiwan’s National Health Insurance Research Database for 2003–2013. From 2004 to 2012, we identified 108,319 newly diagnosed RA patients without previous MACEs, of whom 7,580 patients (7.0%) developed MACEs during follow-up. From these incident RA patients, we included 5,994 MACE cases and 1:4 matched 23,976 non-MACE controls for analysis. The associations of MACEs with comorbidities and use of anti-rheumatic medications within 1 year before the index date were examined using conditional logistic regression analyses. Results: Using multivariable conditional logistic regression analysis, the risk of MACE in RA patients was associated with use of golimumab [odd’s ratio (OR), 0.09; 95% confidence interval (CI), 0.01-0.67], abatacept (OR, 0.13; 95% CI, 0.02–0.93), hydroxychloroquine (OR, 0.90; 95% CI, 0.82-0.99), methotrexate (OR, 0.72; 95% CI, 0.64–0.81), cyclosporin (OR, 1.43; 95% CI, 1.07–1.91), nonsteroidal anti-inflammation drugs (NSAIDs) (OR, 1.36; 95% CI, 1.27–1.46), antiplatelet agent (OR, 2.47; 95% CI, 2.31-2.63), hypertension (without anti-hypertensive agents: OR, 1.04; 95% CI, 0.96-1.12; with anti-hypertensive agents: OR, 1.47; 95% CI, 1.36-1.59), diabetes (OR, 1.27; 95% CI, 1.18-1.37), hyperlipidemia without lipid-lowering agents (OR, 1.09; 95% CI, 1.01-1.17), ischemic heart disease (OR, 1.20; 95% CI, 1.10-1.31), and chronic obstructive pulmonary disease (COPD) (OR, 1.12; 95% CI, 1.03-1.23) in the parsimonious model. The risk of MACE in RA patients also increased markedly in participants younger than 65 years with some comorbidities. Conclusions: This population-based case-control study revealed that the use of golimumab, abatacept, hydroxychloroquine, and methotrexate were associated with a decreased risk of MACE development in newly diagnosed RA patients, while the use of cyclosporin, NSAIDs, and antiplatelet agents, and comorbidities, including hypertension, diabetes, hyperlipidemia without lipid-lowering agent therapy, ischemic heart disease, and COPD, were associated with an increased risk of MACE development in RA patients.

    Abstract: Kynurenine 3-monooxygenase (KMO) is the pivotal enzyme in the kynurenine pathway and is located on the mitochondrial outer membrane. The dysregulation of KMO leads to various neurodegenerative diseases; however, it is rarely mentioned in cancer progression. Our previous study showed that KMO overexpression in canine mammary gland tumors (cMGT) is associated with poor prognosis in cMGT patients. Surprisingly, it was also found that KMO can be located on the cell membranes of cMGT cells, unlike its location in normal cells, where KMO is expressed only within the cytosol. Since cMGT and human breast cancer share similar morphologies and pathogenesis, this study investigated the possibility of detecting surface KMO in human breast cancers and the role of surface KMO in tumorigenesis. Using immunohistochemistry (IHC), flow cytometry (FC), immunofluorescence assay (IFA), and transmission electron microscopy (TEM), we demonstrated that KMO can be aberrantly and highly expressed on the cell membranes of breast cancer tissues and in an array of cell lines. Masking surface KMO with anti-KMO antibody reduced the cell viability and inhibited the migration and invasion of the triple-negative breast cancer cell line, MDA-MB-231. These results indicated that aberrant surface expression of KMO may be a potential therapeutic target for human breast cancers.

    Abstract: Whether tinnitus is associated with pre-existing hypertension remains uncertain. This study explored the association between tinnitus and pre-existing hypertension. Methods: We obtained data on a retrospective cohort of 542 884 cases ≥18 years old with a first-time tinnitus diagnosis from Taiwan’s National Health Insurance Research Database. We used propensity-score matching to select 542 884 matched controls and performed multiple logistic regression analyses to estimate the adjusted odds of prior hypertension among patients with tinnitus versus controls. Results: Bivariate analysis showed no significant difference in the prevalence of prior hypertension between the tinnitus and no-tinnitus groups (35.58% vs 35.5%, P = .617). Univariable logistic regression analysis confirmed the bivariate analysis finding, unadjusted odds of prior hypertension among the tinnitus group relative to controls, 1.002, 95% CI: 0.994-1.010, P = .617). After adjusting for age, sex, monthly income, geographic location and urbanization level, hyperlipidemia, diabetes, hearing loss, obesity, anemia, rheumatoid arthritis, alcohol abuse, nicotine dependence, anxiety disorder, depressive disorder and idiopathic intracranial hypertension, the odds of prior hypertension were similar among the tinnitus and no-tinnitus groups (OR = 1.006, 95% CI: 0.997-1.016, P = .178). Conclusions: Our population-based study found no evidence for an association between tinnitus and pre-existing hypertension.

    Abstract: Pegylated interferon (PEG-IFN)-α-2a improves the hepatitis B e antigen (HBeAg) seroconversion rate in HBeAg-positive chronic hepatitis B patients. However, baseline factors predicting favourable responses to PEG-IFN-α-2a remain largely unknown. Methods A total of 115 HBeAg-positive chronic hepatitis B patients who had a pre-therapy serum alanine amino-transferase (ALT) level over two times the upper limit of normal and received PEG-IFN-α-2a for 6–12 months were consecutively enrolled according to the local reimbursed guidelines. HBeAg seroconversion and combined response defined as HBeAg seroconversion, HBV-DNA level 〈 20,000 IU/ml as well as ALT normalization at 6 months off therapy were primary and secondary therapeutic end points, respectively. Baseline viral factors, including viral load, genotype and major sequences of precore stop codon/ basal core promoter (BCP), and host factors, including three single nucleotide polymorphisms among the HLA-DPA1, HLA-DPB1 and IL28B regions, were determined to correlate with therapeutic end points. Results HBeAg seroconversion and combined response rates were 26.1% and 18.3%, respectively. By multivariate analysis, BCP mutation (OR 8.04, 95% CI 2.00-32.28) and rs3077 G/G genotype (OR 3.49, 95% CI 1.12-10.84) were associated with a higher HBeAg seroconversion rate; BCP mutation (OR 9.28, 95% CI 1.92-44.99) and baseline viral load 〈 2x10 6 IU/ml (OR 4.78, 95% CI 1.37-16.69) were associated with a higher combined response rate. Conclusions BCP mutation is associated with higher HBeAg seroconversion and combined response rates at 6 months off therapy in HBeAg-positive chronic hepatitis B patients treated with PEG-IFN-α-2a. Genetic variants in the HLA-DPA1 region may also affect treatment-induced HBeAg seroconversion.

    Abstract: We used the National Health Insurance (NHI) database to examine the prevalence and incidence of treated major depressive disorder (MDD) and their associated factors. Method: The National Health Research Institute provided a database of 200 432 randomly selected subjects for study. We obtained a population-based random sample aged 15 years or older ( n = 136 045) as a fixed cohort dated 1996 to 2003. We identified study subjects with a principal diagnosis of MDD who had at least one service claim during these years for either ambulatory or inpatient care. Results: From 1996 to 2003, the cumulative treated prevalence increased from 1.67 per 1000 to 17.24 per 1000. From 1997 to 2003, the annual treated incidence increased from 1.89 per 1000 to 2.58 per 1000. A higher incidence of treated MDD was detected in the groups aged 25 to 44 years (hazard ratio [HR] 1.28; 95% confidence interval [CI] , 1.13 to 1.45), 45 to 64 years (HR 1.90; 95%CI, 1.66 to 2.16), and 65 years or older (HR 1.87; 95%CI, 1.59 to 2.20); in female subjects (HR 1.97; 95%CI, 1.80 to 2.15); in those with with an insurance amount of US$1281 or more (HR 1.15; 95%CI, 1.01 to 1.31); in those with a fixed premium (HR 1.44; 95%CI, 1.27 to 1.62); and among those who lived in urban areas (HR 1.22; 95%CI, 1.10 to 1.35). Conclusions: For treated MDD, the prevalence and incidence in Taiwan were lower than in community studies in Western countries. Individuals with MDD are underdiagnosed and undertreated in Taiwan.
