Healthcare Utilization and Its Correlates in Comorbid Type 2 Diabetes Mellitus and Generalized Anxiety Disorder.

This study investigated the healthcare utilization and medical expenditure of type 2 diabetes mellitus (T2DM) patients with generalized anxiety disorder (GAD) and identified the associated factors. The healthcare utilization and expenditure of T2DM patients with (case group) and without (control group) GAD between 2002 and 2013 were examined using the population-based Taiwan National Health Insurance Research Database. Healthcare utilization included outpatient visits and hospitalization; health expenditure included outpatient, inpatient, and total medical expenditure. Moreover, nonpsychiatric healthcare utilization and medical expenditure were distinguished from total healthcare utilization and medical expenditure. The average healthcare utilization, including outpatient visits and hospitalization, was significantly higher for the case group than for the control group (total and nonpsychiatric). The results regarding differences in average outpatient expenditure (total and nonpsychiatric), inpatient expenditure (total and nonpsychiatric), and total expenditure (total and nonpsychiatric) between the case and control groups are inconsistent. Sex, age, income, comorbidities/complications, and the diabetes mellitus complication severity index were significantly associated with outpatient visits, medical expenditure, and hospitalization in the case group (total and nonpsychiatric). Greater knowledge of factors affecting healthcare utilization and expenditure in comorbid individuals may help healthcare providers intervene to improve patient management and possibly reduce the healthcare burden in the future.

Incidence change of postoperative delirium after implementation of processed electroencephalography monitoring during surgery: a retrospective evaluation study.

BACKGROUND: Postoperative delirium (POD) is a common complication in the elderly, which is associated with poor outcomes after surgery. Recognized as predisposing factors for POD, anesthetic exposure and burst suppression during general anesthesia can be minimized with intraoperative processed electroencephalography (pEEG) monitoring. In this study, we aimed to evaluate whether implementation of intraoperative pEEG-guided anesthesia is associated with incidence change of POD. METHODS: In this retrospective evaluation study, we analyzed intravenous patient-controlled analgesia (IVPCA) dataset from 2013 to 2017. There were 7425 patients using IVPCA after a noncardiac procedure under general anesthesia. Patients incapable of operating the device independently, such as cognitive dysfunction or prolonged sedation, were declined and not involved in the dataset. After excluding patients who opted out within three days (N = 110) and those with missing data (N = 24), 7318 eligible participants were enrolled. Intraoperative pEEG has been implemented since July 2015. Participants having surgery after this time point had intraoperative pEEG applied before induction until full recovery. All related staff had been trained in the application of pEEG-guided anesthesia and the assessment of POD. Patients were screened twice daily for POD within 3 days after surgery by staff in the pain management team. In the first part of this study, we compared the incidence of POD and its trend from 2013 January-2015 July with 2015 July-2017 December. In the second part, we estimated odds ratios of risk factors for POD using multivariable logistic regression in case-control setting. RESULTS: The incidence of POD decreased from 1.18 to 0.41% after the administration of intraoperative pEEG. For the age group ≧ 75 years, POD incidence decreased from 5.1 to 1.56%. Further analysis showed that patients with pEEG-guided anesthesia were associated with a lower odd of POD (aOR 0.33; 95% CI 0.18-0.60) than those without after adjusting for other covariates. CONCLUSIONS: Implementation of intraoperative pEEG was associated with a lower incidence of POD within 3 days after surgery, particularly in the elderly. Intraoperative pEEG might be reasonably considered as part of the strategy to prevent POD in the elder population. TRIAL REGISTRATION: Not applicable.

Healthcare burden and factors of type 2 diabetes mellitus with Schizophrenia.

This study investigated healthcare utilization and expenditure for patients with type 2 diabetes mellitus and schizophrenia and associated factors. Healthcare utilization (outpatient visits and hospitalization) and expenditure (outpatient, inpatient, and total medical expenditure) between 2002 and 2013 of patients with T2DM with schizophrenia (case group) and without (control group) were examined using the Taiwan National Health Insurance Research Database. (1) The average total numbers of outpatient visits and hospital admissions of the case group were 35.14 outpatient visits and 1.09 hospital admissions significantly higher than those of the control group in the whole study period (based on every 3-year period). Nonpsychiatric outpatient visits and nonpsychiatric hospital admissions were significantly more numerous for the case group. (2) The total outpatient expenditure, total inpatient expenditure, and total medical expenditure of the case group were NT$65,000, NT$170,000, and NT$235,000 significantly higher than those of the control group, respectively. Nonpsychiatric outpatient expenditure was significantly lower for the case group, but the inpatient and total nonpsychiatric medical expenditure were similar between groups. (3) Patients who were elder of low income, with complications, and high diabetes mellitus complication severity index had higher total numbers of outpatient visits and hospitalizations and medical expenditure. (4) Women had a higher number of outpatient visits but a lower number of hospitalization and medical expenditure. Lower non-psychiatric outpatient expenditure despite more visits indicated non-psychiatrist may not understand schizophrenia patients and cannot communicate well with them, leading to neglect of medical evaluation and treatment that should be carried out.

Risk of adverse fetal outcomes following nonobstetric surgery during gestation: a nationwide population-based analysis.

BACKGROUND: Literature suggests that nonobstetric surgery during gestation is associated with a higher risk of spontaneous abortion, prematurity, and a higher cesarean section rate, but the direct impact on fetal outcomes is still unclear. In this study, we aimed to investigate whether nonobstetric surgery during pregnancy is associated with negative fetal outcomes by analysing a nation-wide database in Taiwan. METHODS: This population-based retrospective observational case-control study was based on the linkage of Taiwan's National Health Insurance Research Database, Birth Reporting Database, and Maternal and Child Health Database between 2004 and 2014. For every pregnancy with nonobstetric surgery during gestation, four controls were randomly matched according to maternal age and delivery year. We estimated adjusted odds ratios (aOR) and 95% confidence intervals (CIs) of adverse fetal outcomes with the non-surgery group as the reference. The primary outcomes involved stillbirth, prematurity, low birth weight, low Apgar scores, and neonatal and infant death. RESULTS: Among 23,721 identified pregnancies, 4,747 underwent nonobstetric surgery. Pregnancies with nonobstetric surgery had significantly higher risks of prematurity (aOR: 1.46; 95% CI: 1.31-1.62), lower birth weight (aOR: 1.49; 95% CI: 1.33-1.67), Apgar scores < 7 (1 min, aOR: 1.58; 95% CI: 1.33-1.86; 5 min, aOR: 1.34; 95% CI: 1.03-1.74), neonatal death (aOR: 2.01; 95% CI: 1.18-3.42), and infant death (aOR: 1.69; 95% CI: 1.12-2.54) than those without nonobstetric surgery after adjustment for socioeconomic deprivation, hospital level, and other comorbidities. Surgery performed in the third trimester was associated with a significantly increased rate of prematurity (aOR: 1.38; 95% CI: 1.03-1.85), but lower rates of stillbirth (aOR: 0.1; 95% CI: 0.01-0.75) and Apgar score < 7 at the 5th minute (aOR: 0.2; 95% CI: 0.05-0.82), than surgery performed in the first trimester. CONCLUSIONS: Pregnancies with nonobstetric surgery during gestation were associated with increased risks of prematurity, low birth weight, low Apgar scores, neonatal and infant death, longer admission, and higher medical expenses than those without surgery. Furthermore, surgery in the third trimester was associated with a higher rate of prematurity than surgery performed in the first trimester. TRIAL REGISTRATION: Not applicable.

Implementation of a machine learning application in preoperative risk assessment for hip repair surgery.

BACKGROUND: This study aims to develop a machine learning-based application in a real-world medical domain to assist anesthesiologists in assessing the risk of complications in patients after a hip surgery. METHODS: Data from adult patients who underwent hip repair surgery at Chi-Mei Medical Center and its 2 branch hospitals from January 1, 2013, to March 31, 2020, were analyzed. Patients with incomplete data were excluded. A total of 22 features were included in the algorithms, including demographics, comorbidities, and major preoperative laboratory data from the database. The primary outcome was a composite of adverse events (in-hospital mortality, acute myocardial infarction, stroke, respiratory, hepatic and renal failure, and sepsis). Secondary outcomes were intensive care unit (ICU) admission and prolonged length of stay (PLOS). The data obtained were imported into 7 machine learning algorithms to predict the risk of adverse outcomes. Seventy percent of the data were randomly selected for training, leaving 30% for testing. The performances of the models were evaluated by the area under the receiver operating characteristic curve (AUROC). The optimal algorithm with the highest AUROC was used to build a web-based application, then integrated into the hospital information system (HIS) for clinical use. RESULTS: Data from 4,448 patients were analyzed; 102 (2.3%), 160 (3.6%), and 401 (9.0%) patients had primary composite adverse outcomes, ICU admission, and PLOS, respectively. Our optimal model had a superior performance (AUROC by DeLong test) than that of ASA-PS in predicting the primary composite outcomes (0.810 vs. 0.629, p < 0.01), ICU admission (0.835 vs. 0.692, p < 0.01), and PLOS (0.832 vs. 0.618, p < 0.01). CONCLUSIONS: The hospital-specific machine learning model outperformed the ASA-PS in risk assessment. This web-based application gained high satisfaction from anesthesiologists after online use.

Djulis (Chenopodium formosanum) and Its Bioactive Compounds Protect Human Lung Epithelial A549 Cells from Oxidative Injury Induced by Particulate Matter via Nrf2 Signaling Pathway.

The protective effects of water extracts of djulis (Chenopodium formosanum) (WECF) and their bioactive compounds on particulate matter (PM)-induced oxidative injury in A549 cells via the nuclear factor-erythroid 2-related factor 2 (Nrf2) signaling were investigated. WECF at 50-300 µg/mL protected A549 cells from PM-induced cytotoxicity. The cytoprotection of WECF was associated with decreases in reactive oxygen species (ROS) generation, thiobarbituric acid reactive substances (TBARS) formation, and increases in superoxide dismutase (SOD) activity and glutathione (GSH) contents. WECF increased Nrf2 and heme oxygenase-1 (HO-1) expression in A549 cells exposed to PM. SP600125 (a JNK inhibitor) and U0126 (an ERK inhibitor) attenuated the WECF-induced Nrf2 and HO-1 expression. According to the HPLC-MS/MS analysis, rutin (2219.7 µg/g) and quercetin derivatives (2648.2 µg/g) were the most abundant bioactive compounds present in WECF. Rutin and quercetin ameliorated PM-induced oxidative stress in the cells. Collectively, the bioactive compounds present in WECF can protect A549 cells from PM-induced oxidative injury by upregulating Nrf2 and HO-1 via activation of the ERK and JUN signaling pathways.

Satisfaction in parturients receiving epidural analgesia after prenatal shared decision-making intervention: a prospective, before-and-after cohort study.

BACKGROUND: The explanation of epidural analgesia by anesthesiologist would often begin after the parturient is admitted to the hospital. Because of labor pain, the decision of receiving epidural analgesia would often be made by the family members, instead of the parturient herself. We aimed to test whether earlier prenatal shared decision-making (SDM) interventions increase parturient's comprehension and satisfaction of epidural labor analgesia, compared to conventional explanation after labor pain begun. METHODS: During the 28th week of gestation, we provided the SDM parturient health education as well as a leaflet with quick response codes. Scanning the code would link to education videoclips which explained what epidural analgesia is and its advantages and disadvantages. Original routine practice group parturients received explanation of analgesia after admission for delivery. To measure the satisfaction of labor pain service, the accessibility of information, and the communication with medical staff, we designed a questionnaire with reference to (1) Pregnancy and Maternity Care Patients' Experiences Questionnaire (PreMaPEQ), (2) Preterm Birth Experience and Satisfaction Scale (P-BESS), and (3) Women's Views of Birth Labor Satisfaction Questionnaire (WOMBLSQ). The questionnaire was amended after a pretest involving 30 parturients who had received epidural analgesia. Scree test analysis and exploratory factor analysis were performed; then, the questionnaire was revised again. A total of 200 valid questionnaires were collected-100 each from the original routine practice group and the SDM group. RESULTS: The SDM group reported significantly higher satisfaction with and understanding of epidural analgesia, and a significantly higher satisfaction with the information received, and the quality of pain relief. After SDM intervention, significant increasement of the average satisfaction scores in question "my epidural is effective" (9.10%; mean difference: 0.38; 95% confidence interval, 0.17 ~ 0.59; p < 0.001) and "The effect of epidural is just as what I have expected" (10.41%; mean difference: 0.41; 95% confidence interval, 0.18 ~ 0.64; p < 0.001) was demonstrated. CONCLUSIONS: An earlier prenatal SDM intervention with sufficient information through videoclips increased parturients' comprehensions and satisfaction of epidural analgesia service.

Prophylactic diphenhydramine attenuates postoperative catheter-related bladder discomfort in patients undergoing gynecologic laparoscopic surgery: a randomized double-blind clinical study.

BACKGROUND: To evaluate the effectiveness of diphenhydramine, an antihistamine with anti-muscarinic properties, for prevention of postoperative catheter-related bladder discomfort (CRBD). METHODS: Ninety-six ASA physical status I and II adult female patients (20-60 years) scheduled for elective gynecologic laparoscopic surgery were included. Patients were randomized into two groups of 48 patients each. All patients received a detailed preoperative explanation of the possible consequences of CRBD. The control group received normal saline 2 ml, whereas the diphenhydramine group received diphenhydramine 30 mg intravenously after induction of general anesthesia. Then, all patients were catheterized with a 14F Foley catheter and the balloon was inflated with 10 ml of distilled water. All patients who complained of CRBD in the postoperative room were appeased with nursing. Ketorolac 30 mg was used as the rescue drug on patients' request or when the patient was evaluated as having moderate or severe CRBD. Bladder discomfort and its severity were assessed at 1, 2 and 6 h postoperatively. The severity of CRBD was graded as none, mild, moderate and severe. Adverse effects of diphenhydramine such as sedation, dry mouth or GI upset were recorded. RESULTS: The incidence of CRBD was lower in the diphenhydramine group compared with the control group at 2 h (34.8 vs. 58.7%, p = 0.02) and 6 h (23.9 vs. 56.5%, p < 0.01) postoperatively. Diphenhydramine treatment also reduced the severity of CRBD at 6 h postoperatively (p = 0.01). Moreover, the request for rescue for CRBD was lower in diphenhydramine group at 2 h (8.7 vs. 26.1%, p = 0.03). There were no significant differences in side effects, such as sedation, dry mouth or gastrointestinal upset between the two groups (p > 0.05). CONCLUSION: Prophylactic diphenhydramine 30 mg at induction of general anesthesia reduced the incidence and severity of postoperative bladder discomfort without significant side effects in patients receiving gynecologic laparoscopic surgery.

Pregnancy outcomes following nonobstetric surgery during gestation: a nationwide population-based case-control study in Taiwan.

BACKGROUND: Whether nonobstetric surgery during gestation is associated with a higher risk of spontaneous abortion or adverse delivery outcomes is still unclear. METHODS: We performed a retrospective case-control study using a Longitudinal Health Insurance Database (LHID 2000) containing claim-data of 1 million randomly selected beneficiaries. We compared the incidences and estimated the adjusted odds ratios (aOR) with 95% confidence interval (95% CI) for spontaneous abortion, adverse delivery outcomes, cesarean delivery, and prolonged hospital stay to determine the risk of adverse outcomes in women who had nonobstetric surgery during gestation as compared to those who did not have any surgery during gestation. RESULTS: After exclusion, we were left with 114,852 delivery and 3999 abortion cases in our study; and 462 (0.39%) of them had nonobstetric surgery under general or regional anesthesia during pregnancy. The leading surgeries were repair of cervical os (33.12%), appendectomy (17.32%), ovarian surgeries (13.64%), and fixation of fractured bone (8.01%).The risk of spontaneous abortion (4.23% vs. 2.43%, aOR:1.53; 95% CI: 1.01-2.31), antepartum hemorrhage (7.14% vs. 2.83%, aOR: 2.51; 95% CI: 1.74-3.61), pre-eclampsia/eclampsia (2.60% vs. 1.01%, aOR: 2.35; 95% CI: 1.30-4.23), gestational diabetes (2.38% vs. 0.69%, aOR: 3.12; 95% CI: 1.69-5.78), prematurity (9.06 vs. 4.90%, aOR: 3.31; 95% CI: 2.54-4.31), cesarean section (43.55% vs. 33.76%, aOR: 1.41; 95% CI: 1.17-1.71), and prolonged hospital stay (1.82% vs. 5.91%, aOR: 3.23; 95% CI: 2.16-4.83) were higher in those women who had nonobstetric surgery after adjusting for age and comorbidities. CONCLUSIONS: Nonobstetric surgery during gestation were associated with a higher risk of spontaneous abortion, adverse delivery outcomes, cesarean section, and prolonged hospital stay.

The Inhibitory Effects of Djulis (Chenopodium formosanum) and Its Bioactive Compounds on Adipogenesis in 3T3-L1 Adipocytes.

The aim of this study was to provide new insights into the role of the ethanolic extracts of Djulis (Chenopodium formosanum, EECF) and its bioactive compounds in preventing adipogenesis in 3T3-L1 adipocytes. The results demonstrated EECF significantly inhibited oil red O-stained material (OROSM), triglyceride levels and glycerol-3-phosphate dehydrogenase (GPDH) activity in 3T3-L1 adipocytes. The expression of the critical molecules involved in lipid synthesis such as PPARγ, C/EBPα and SREBP-1c was attenuated in EECF-treated cells. According to HPLC-DAD and HPLC-MS/MS analysis, rutin, kaempferol, betanin and another nine compounds were present in EECF. The suppression of lipid accumulation by rutin, kaempferol and betanin occurred by decreasing the gene expression of PPARγ, C/EBPα and SREBP-1c. Taken together, these findings suggest the presence of bioactive compounds in EECF may partly account for the anti-adipogenesis of EECF and EECF is therefore a potentially lipid lowering functional food.

New insights into Blimp-1 in T lymphocytes: a divergent regulator of cell destiny and effector function.

B lymphocyte-induced maturation protein-1 (Blimp-1) serves as a master regulator of the development and function of antibody-producing B cells. Given that its function in T lymphocytes has been identified within the past decade, we review recent findings with emphasis on its role in coordinated control of gene expression during the development, differentiation, and function of T cells. Expression of Blimp-1 is mainly confined to activated T cells and is essential for the production of interleukin (IL)-10 by a subset of forkhead box (Fox)p3+ regulatory T cells with an effector phenotype. Blimp-1 is also required to induce cell elimination in the thymus and critically modulates peripheral T cell activation and proliferation. In addition, Blimp-1 promotes T helper (Th) 2 lineage commitment and limits Th1, Th17 and follicular helper T cell differentiation. Furthermore, Blimp-1 coordinates with other transcription factors to regulate expression of IL-2, IL-21 and IL-10 in effector T lymphocytes. In CD8+ T cells, Blimp-1 expression is distinct in heterogeneous populations at the stages of clonal expansion, differentiation, contraction and memory formation when they encounter antigens. Moreover, Blimp-1 plays a fundamental role in coordinating cytokine receptor signaling networks and transcriptional programs to regulate diverse aspects of the formation and function of effector and memory CD8+ T cells and their exhaustion. Blimp-1 also functions as a gatekeeper of T cell activation and suppression to prevent or dampen autoimmune disease, antiviral responses and antitumor immunity. In this review, we discuss the emerging roles of Blimp-1 in the complex regulation of gene networks that regulate the destiny and effector function of T cells and provide a Blimp-1-dominated transcriptional framework for T lymphocyte homeostasis.

Epidemiological profile and obstetric outcomes of patients with peripartum congestive heart failure in Taiwan: a retrospective nationwide study.

BACKGROUND: During pregnancy, the hyperdynamic physiology of circulation can exacerbate many cardiovascular disorders. Congestive heart failure (CHF) usually occurs during late pregnancy, which is significantly associated with a high level of maternal and neonatal morbidities and mortalities. The profile of women who develop peripartum CHF (PCHF) is unknown. We investigated the epidemiological profiles of PCHF. METHODS: In this retrospective cohort study, PCHF patients were identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes in Taiwan's National Health Insurance Research Database. Risk factors and obstetric outcomes were compared in women with and without PCHF. RESULTS: From 2,115,873 birth-mothers in Taiwan between 1997 and 2013, we identified 512 with PCHF (incidence: 24.20/105). More women with than without PCHF were older (≥ 35, 18.16% vs. 9.62%), and had more multifetal gestations (7.42% vs. 1.40%), gestational hypertension (HTN) (19.2% vs. 1.31%), and gestational diabetes mellitus (4.10% vs. 0.67%). After the analysis had been adjusted for confounders, the leading comorbidities associated with PCHF were structural heart diseases (adjusted odds ratio [aOR]: 67.21; 95% confidence interval [CI]: 54.29-83.22), pulmonary diseases (aOR: 13.12; 95% CI: 10.28-16.75), chronic HTN (aOR: 11.27; 95% CI: 6.94-18.28), thyroid disease (aOR: 9.53; 95% CI: 5.27-17.23), and gestational HTN (aOR: 5.16; 95% CI: 3.89-6.85). PCHF patients also had a higher rate of cesarean sections (66.41% vs. 34.46%; p < 0.0001). CONCLUSION: Maternal structural heart diseases, pulmonary diseases, thyroid disorders, and preexisting or gestational HTN are associated with a higher risk of developing PCHF. Birth-mothers with PCHF also had a higher risk of caesarean section and adverse outcomes, including maternal death. Our findings should benefit healthcare providers, and government and health insurance policy makers.

CD200 in growing rat lungs: developmental expression and control by dexamethasone.

CD200 belongs to cell adhesion molecules of the immunoglobulin superfamily. It lacks intracellular signaling motifs and exerts immunosuppressive effect in various tissues. We have reported previously that CD200 is predominantly associated with the capillary network in the alveolar septum of adult rats. The alveolar endothelial cells express CD200, which is confined to their luminal cell membrane facing the blood-air barrier. Our present results show that lung CD200 protein increases gradually with advancing age, being maximally expressed in the early postnatal (P) period. CD200 protein expression, however, declines at P5 but increases again after P7, reaching the adult level at P21. In developing lungs in fetal and neonatal stages, double-immunofluorescence staining has confirmed intense CD200 immunoreactivity delineating the vascular profiles in the double layers of the alveolar capillaries; this staining becomes diffuse and patchy with time. Unlike in adult lungs, immunoelectron microscopy has revealed that CD200 expression in fetal and early postnatal lungs is localized over the entire luminal cell membrane and in the cytoplasm of the endothelia. CD200 expression is progressively redistributed to a specific luminal domain of alveolar endothelia during pulmonary microvascular maturation. In neonatal rats treated with dexamethasone, the amount of lung CD200 significantly increases and is also elevated with time. Upregulation of endothelial CD200 has further been confirmed in isolated pulmonary microvascular endothelial cells treated with dexamethasone. Thus, lung CD200 is developmentally regulated, possibly under hormonal influence.

Propensity Score-matched Comparison of Postoperative Adverse Outcomes between Geriatric Patients Given a General or a Neuraxial Anesthetic for Hip Surgery: A Population-based Study.

BACKGROUND: The effects of the mode of anesthesia on major adverse postoperative outcomes in geriatric patients are still inconclusive. The authors hypothesized that a neuraxial anesthetic (NA) rather than a general anesthetic (GA) would yield better in-hospital postoperative outcomes for geriatric patients undergoing hip surgery. METHODS: The authors used data from Taiwan's 1997-2011 in-patient claims database to evaluate the effect of anesthesia on in-hospital outcomes. The endpoints were mortality, stroke, transient ischemic stroke, myocardial infarction, respiratory failure, and renal failure. Of the 182,307 geriatric patients who had hip surgery, a GA was given to 53,425 (29.30%) and an NA to 128,882 (70.70%). To adjust for baseline differences and selection bias, patients were matched on propensity scores, which left 52,044 GA and 52,044 NA patients. RESULTS: GA-group patients had a greater percentage and higher odds of adverse in-hospital outcomes than did NA-group patients: death (2.62 vs. 2.13%; odds ratio [OR], 1.24; 95% CI, 1.15 to 1.35; P < 0.001), stroke (1.61 vs. 1.38%; OR, 1.18, 95% CI, 1.07 to 1.31; P = 0.001), respiratory failure (1.67 vs. 0.63%; OR, 2.71; 95% CI, 2.38 to 3.01; P < 0.001), and intensive care unit admission (11.03 vs. 6.16%; OR, 1.95; 95% CI, 1.87 to 2.05; P < 0.001), analyzed using conditional logistic regression. Moreover, patients given a GA had longer hospital stays (10.77 ± 8.23 vs. 10.44 ± 6.67 days; 95% CI, 0.22 to 0.40; P < 0.001) and higher costs (New Taiwan Dollars [NT$] 86,606 ± NT$74,162 vs. NT$74,494 ± NT$45,264; 95% CI, 11,366 to 12,859; P < 0.001). CONCLUSION: For geriatric patients undergoing hip surgery, NA was associated with fewer odds of adverse outcomes than GA.

Epidemiological profile of Dupuytren's disease in Taiwan (Ethnic Chinese): a nationwide population-based study.

BACKGROUND: The epidemiologic profile of ethnic Chinese patients with Dupuytren's disease is unknown. We therefore investigated the epidemiology of Dupuytren's disease using Taiwan's National Health Insurance Research Database. METHODS: Patients who filed claims for treatment for Dupuytren's disease between January 2000 and December 2011 were identified in the database. Age- and gender-specific incidences were estimated by dividing the incidence number by population data. RESULTS: We identified 1,078 patients with Dupuytren's disease (681 men, 397 women; male/female ratio: 1:1.72). The annual incidence rate ranged from 0.39-0.63/10(5) for men and 0.14-0.44/10(5) for women. A trend analysis revealed a rising trend in the annual incidence from 2001 to 2011 (p = 0.0199). The prevalence rate increased steadily from 0.46/10(5) in 2000 to 4.52/10(5) in 2011 (p = 0.0186). The mean age at onset was significantly higher in men than in women (60.7 ± 18.4 vs. 53.7 ± 15.5 years). Peak age at onset for men was 70-79 (28.1%) and for women was 50-59 (33.5%). Men > 60 years old had higher incidence rates than did women (incidence rate ratios: 2.0, 4.5, and 6.6 for those 60-69, 70-79, and ≥ 80, respectively). Hypertension (29.6%), diabetes mellitus (21.9%), hyperlipidemia (14.8%), ischemic heart disease (10.5%), and chronic obstructive pulmonary disease (8.0%) were the most common comorbidities. CONCLUSIONS: The incidence and prevalence of Dupuytren's disease and the male/female ratio were significantly lower in ethnic Chinese than in Western ethnic groups. Moreover, the age at onset was significantly lower in ethnic Chinese women. However, the incidences of three comorbidities (hypertension, diabetes mellitus, and hyperlipidemia) were similar to those in other ethnicities.

T cell-specific BLIMP-1 deficiency exacerbates experimental autoimmune encephalomyelitis in nonobese diabetic mice by increasing Th1 and Th17 cells.

Recently, we demonstrated that B lymphocyte-induced maturation protein 1 (BLIMP-1) has a role in regulating the differentiation and effector function of Th1 and Th17 cells. As these cells play critical roles in the induction and pathogenesis of experimental autoimmune encephalomyelitis (EAE), we investigated the potential role of T cell BLIMP-1 in modulating MOG35-55-induced EAE. We established T cell-specific BLIMP-1 conditional knockout (CKO) NOD mice to dissect the role of BLIMP-1 in EAE using loss-of-function model. Our results indicate that EAE severity is dramatically exacerbated in CKO mice. The numbers of CNS-infiltrating Th1, Th17, IFN-γ(+)IL-17A(+), and IL-21(+)IL-17A(+) CD4(+) T cells are remarkably increased in brain and spinal cord of CKO mice. Moreover, the ratio of Tregs/effectors and IL-10 production of Tregs are significantly downregulated in CNS of CKO mice. We conclude that BLIMP-1 suppresses autoimmune encephalomyelitis via downregulating Th1 and Th17 cells and impairing Treg cells.

End-stage renal disease after hypertensive disorders in pregnancy.

OBJECTIVE: The purpose of this study was to determine the long-term postpartum risk of end-stage renal disease in women with hypertensive disorders in pregnancy. Although most women with hypertensive disorders in pregnancy recover after delivery, some may experience acute renal failure. STUDY DESIGN: We searched Taiwan's National Health Insurance Research Database to identify women with hypertensive disorders in pregnancies and deliveries between 1998 and 2002. All cases were followed for a maximum of 11 years (median, 9 years; interquartile range, 7.79-10.02 years) to estimate the incidence of end-stage renal disease; Cox regression analysis that was adjusted for potential confounding was used to determine the relative risk. RESULTS: Of the 13,633 women with hypertensive disorders in pregnancy, 46 experienced end-stage renal disease. Women with hypertensive disorders in pregnancy had a risk of end-stage renal disease that was 10.64 times greater than did women without them (95% confidence interval [CI], 7.53-15.05). The risk was highest in women with a history of preeclampsia superimposed on chronic hypertension (hazard ratio, 44.72; 95% CI, 22.59-88.51). Women with gestational hypertension had a higher risk of end-stage renal disease than did women without hypertensive disorders in pregnancy (hazard ratio, 5.82; 95% CI, 2.15-15.77). CONCLUSION: Women with hypertensive disorders in pregnancy have a higher risk of postpartum end-stage renal disease, regardless of which type of hypertensive disorder they have. Women with a history of hypertensive disorders in pregnancy are encouraged to have regular postpartum checkups, especially of renal function.

Renal transplantation: relationship between hospital/surgeon volume and postoperative severe sepsis/graft-failure. a nationwide population-based study.

UNLABELLED: BACKGROUND AND OBJECTS: We explored the relationship between hospital/surgeon volume and postoperative severe sepsis/graft-failure (including death). METHODS: The Taiwan National Health Insurance Research Database claims data for all patients with end-stage renal disease patients who underwent kidney transplantation between January 1, 1999, and December 31, 2007, were reviewed. Surgeons and hospitals were categorized into two groups based on their patient volume. The two primary outcomes were severe sepsis and graft failure (including death). The logistical regressions were done to compute the Odds ratios (OR) of outcomes after adjusting for possible confounding factors. Kaplan-Meier analysis was used to calculate the cumulative survival rates of graft failure after kidney transplantation during follow-up (1999-2008). RESULTS: The risk of developing severe sepsis in a hospital in which surgeons do little renal transplantation was significant (odds ratio [OR]; p = 0.0115): 1.65 times (95% CI: 1.12-2.42) higher than for a hospital in which surgeons do many. The same trend was true for hospitals with a low volume of renal transplantations (OR = 2.39; 95% CI: 1.62-3.52; p < 0.0001). The likelihood of a graft failure (including death) within one year for the low-volume surgeon group was 3.1 times higher than for the high-volume surgeon group (p < 0.0001); the trend was similar for hospital volume. Female patients had a lower risk than did male patients, and patients ≥ 55 years old and those with a higher Charlson comorbidity index score, had a higher risk of severe sepsis. CONCLUSIONS: We conclude that the risk of severe sepsis and graft failure (including death) is higher for patients treated in hospitals and by surgeons with a low volume of renal transplantations. Therefore, the health authorities should consider exporting best practices through educational outreach and regulation and then providing transparent information for public best interest.

The impact of comorbidity on survival after hemorrhagic stroke among dialysis patients: a nationwide population-based study.

BACKGROUND: This study was aimed at determining the outcome and examining the association between comorbidities and mortality after intracerebral hemorrhage in chronic dialysis patients. METHODS: We used the Taiwan National Health Insurance Research Database and enrolled patients who underwent maintenance dialysis between 2000 and 2007. Annual incidence of intracerebral hemorrhage in patients receiving dialysis from 2000 to 2007 was determined. To identify predictors of hemorrhagic stroke, we used logistic regression model to estimate the relative ratio of factors for intracerebral hemorrhage in the most recent cohort (2007). The cumulative survival rate and comorbid conditions associated with mortality after intracerebral hemorrhage among all dialysis patients between 2000 and 2007 was calculated using the Kaplan-Meier method and Cox regression analysis. RESULTS: We identified 57,261 patients on maintenance dialysis in the cohort of 2007, and 340 patients had history of intracerebral hemorrhage among them. Hypertension was the most common comorbidity of dialysis patients. The incidence rate of intracerebral hemorrhage among dialysis patients was about 0.6%. Adjusted logistic regression model showed that male gender, middle age (45-64 years), hypertension, and previous history of stroke were the independent predictors for the occurrence of intracerebral hemorrhage among chronic dialysis patients. 1,939 dialysis patients with development of intracerebral hemorrhage in the analysis period from 2000 to 2007 were identified. In-hospital mortality was high (36.15%) following intracerebral hemorrhage. They were followed up after intracerebral hemorrhage for a mean time of 41.56 months. Adjusted Cox regression analyses demonstrated that the factors independently associated with mortality after intracerebral hemorrhage among dialysis patients included diabetes mellitus, malignancy and a history of prior stroke. CONCLUSIONS: Dialysis patients who have history of prior stroke, diabetes and malignancy have worse survival than patients without these comorbidities. Attention must focus on providing optimal medical care after hemorrhagic stroke for these target groups to reduce mortality.
