Inflammatory markers such as interleukin (IL)-6 and tumour necrosis factor-alpha (TNF-α) are elevated in dialysis patients and can predict cardiovascular events and all-cause mortality. Endotoxin is ...an important source and also another marker of inflammation in patients with chronic kidney disease. The aim of this study was to evaluate the impact of oral probiotics on serum levels of endotoxemia and cytokines in peritoneal dialysis (PD) patients. The decline of residual renal function, peritonitis episodes, and cardiovascular events were also recorded. From July 2011 to June 2012, a randomised, double-blind, placebo-controlled trial was conducted in PD patients. The intervention group received one capsule of probiotics containing 109 cfu Bifobacterium bifidum A218, 109 cfu Bifidobacterium catenulatum A302, 109 cfu Bifidobacterium longum A101, and 109 cfu Lactobacillus plantarum A87 daily for six months, while the placebo group received similar capsules containing maltodextrin for the same duration. Levels of serum TNF-α, interferon gamma, IL-5, IL-6, IL-10, IL-17, and endotoxin were measured before and six months after intervention. 39 patients completed the study (21 in the probiotics group and 18 in the placebo group). In patients receiving probiotics, levels of serum TNF-α, IL-5, IL-6, and endotoxin significantly decreased after six months of treatment, while levels of serum IL-10 significantly increased. In contrast, there were no significant changes in levels of serum cytokines and endotoxin in the placebo group after six months. In addition, the residual renal function was preserved in patients receiving probiotics. In conclusion, probiotics could significantly reduce the serum levels of endotoxin, pro-inflammatory cytokines (TNF-α and IL-6), IL-5, increase the serum levels of anti-inflammatory cytokine (IL-10), and preserve residual renal function in PD patients.
Background and purpose
Restless legs syndrome (RLS) is an underestimated movement disorder in patients with end‐stage renal disease (ESRD). Several clinical and laboratory factors were inconsistently ...reported to associate with RLS. We aim to perform a large‐scale multicenter study to investigate the possible associated risk factors of RLS in patients with ESRD in Taiwan, a country with the highest incidence of uremia in the world.
Methods
From October 2009 to October 2011, we constitutively recruited 1130 patients with ESRD from 17 hemodialysis centers. Demographic, laboratory data, presence and severity of RLS were collected. Odds ratios (ORs) were estimated by logistic regression models.
Results
We found the prevalence of RLS to be 25.3% in patients with ESRD. Having type 2 diabetes OR = 3.61 (2.27–5.77), P < 0.01, low serum transferrin saturation OR = 1.42 (1.01–2.03), P < 0.05 and duration of dialysis OR = 1.09 (1.03–1.14), P < 0.01 were associated with RLS. In contrast, high serum hemoglobin level was inversely associated with RLS OR = 0.61 (0.40–0.89), P < 0.05. RLS has a significant impact on sleep quality in dialysis patients. Among patients with RLS, history of type 2 diabetes OR = 4.04 (1.65–10.79), P < 0.05, low serum hemoglobin level OR = 5.41 (2.43–13.12), P < 0.01 and duration of dialysis OR = 1.01 (1.01–1.02), P < 0.01 were associated with increased severity of RLS.
Conclusions
Our findings demonstrated that RLS is common in Taiwanese dialysis patients. Clinicians should have a high suspicion for the presence of RLS symptoms in patients with ESRD, especially those with type 2 diabetes, anemia, low serum iron status and long duration of dialysis.
Summary
Bone mineral density (BMD) may be increased due to vertebral compression fractures (VCF). Our study showed trabecular bone scores (TBS) was less affected than BMD by fractured vertebrae. The ...TBS of most compression fractures, including old and recent VCF with mild or moderate deformity and old VCF with severe deformity, could still be used in predicting fracture risk.
Introduction
Trabecular bone score (TBS), a noninvasive tool estimating bone microarchitecture, provides complementary information to lumbar spine bone mineral density (BMD). Lumbar spine BMD might be increased due to both degenerative disease and vertebral compression fractures (VCF). Lumbar spine TBS has been confirmed not influenced by osteoarthrosis, but the effects of VCF are still not been well evaluated. This study aimed to investigate whether lumbar spine TBS was affected by fractured vertebrae.
Methods
We studied postmenopausal women and men above 50 years old who underwent DXA between January 1, 2017, and May 31, 2019. By calculating the difference of BMD and TBS between L1 and the mean of L2-3, the study compared the difference of values between the control group and fracture group to determine the effects of fractured vertebrae on BMD and TBS.
Results
A total of 377 participants were enrolled with 202 in the control group (157 females; age: 68.06 ± 6.47 years) and 175 in the fracture group (147 females; age: 71.71 ± 9.44 years). The mean BMD of the L1 vertebrae in the fracture group was significantly higher than that in the control group (
p
< 0.0001). There was no significant difference between the mean differences of TBS between L1 and the means of L2-3 vertebrae in the control group and the most compression fractures, including old and recent VCF with mild or moderate deformity and old VCF with severe deformity.
Conclusion
Lumbar spine TBS, unlike BMD, is less affected by fractured vertebrae. The TBS of most compression fractures, including old and recent VCF with mild or moderate deformity and old VCF with severe deformity, could still be used in predicting fracture risk.
Summary
Background
Epidemiological investigations have examined the association between type 1 diabetes mellitus (T1DM) and atopic disease, but have obtained conflicting results.
Objectives
To ...analyse the association between T1DM and atopic dermatitis (AD) in a population‐based, retrospective cohort study that investigated the hypothesis that childhood T1DM is a risk factor for subsequent AD.
Methods
From claims data of the National Health Insurance programme of Taiwan, we identified 3386 patients with T1DM newly diagnosed from 1998 to 2011 and 12 725 randomly selected controls without T1DM. These were frequency matched by age, sex and year of diagnosis. Both cohorts were followed up until the end of 2011 to evaluate the AD risk. We used Cox proportional hazards regression models to analyse the risk of AD.
Results
The overall incidence rate of AD was 1·40‐fold (significantly) higher in the T1DM cohort than in the non‐T1DM cohort (3·31 vs. 2·35 per 1000 person years). After adjustment for potential risk factors, the overall risk of AD remained higher in the T1DM cohort adjusted hazard ratio (HR) 1·76, 95% confidence interval (CI) 1·29–2·39 than in those without T1DM. Compared with the non‐T1DM cohort, the patients with T1DM with more emergency room visits (adjusted HR 30·1, 95% CI 18·7–48·5) or hospitalizations (adjusted HR 70·3, 95% CI 45·6–114·5) had a higher risk of subsequent AD.
Conclusions
This nationwide, retrospective cohort study demonstrates that childhood T1DM may increase the risk of AD.
What's already known about this topic?
Some studies have reported that atopic dermatitis (AD) is associated with a lower risk of type 1 diabetes mellitus (T1DM).
An inverse association was theorized between T1DM and AD because the T‐helper 1/2 immune responses of these two diseases are mutually inhibitory.
What does this study add?
This nationwide, retrospective cohort study demonstrates that childhood T1DM may increase the risk of AD.
The overall AD incidence rate was 1·40‐fold (significantly) higher in the T1DM cohort than in the non‐T1DM cohort (3·31 vs. 2·35 per 1000 person years).

A number of patient-specific and leukemia-associated factors are related to the poor outcome in older patients with acute myeloid leukemia (AML). However, comprehensive studies regarding the impact ...of genetic alterations in this group of patients are limited. In this study, we compared relevant mutations in 21 genes between AML patients aged 60 years or older and those younger and exposed their prognostic implications. Compared with the younger patients, the elderly had significantly higher incidences of PTPN11, NPM1, RUNX1, ASXL1, TET2, DNMT3A and TP53 mutations but a lower frequency of WT1 mutations. The older patients more frequently harbored one or more adverse genetic alterations. Multivariate analysis showed that DNMT3A and TP53 mutations were independent poor prognostic factors among the elderly, while NPM1 mutation in the absence of FLT3/ITD was an independent favorable prognostic factor. Furthermore, the status of mutations could well stratify older patients with intermediate-risk cytogenetics into three risk groups. In conclusion, older AML patients showed distinct genetic alterations from the younger group. Integration of cytogenetics and molecular mutations can better risk-stratify older AML patients. Development of novel therapies is needed to improve the outcome of older patients with poor prognosis under current treatment modalities.
Simultaneous enhancement of out-coupling efficiency, internal quantum efficiency, and color purity in thermally activated delayed fluorescence (TADF) emitters is highly desired for the practical ...application of these materials. We designed and synthesized two isomeric TADF emitters, 2DPyM-mDTC and 3DPyM-pDTC, based on di(pyridinyl)methanone (DPyM) cores as the new electron-accepting units and di(tert-butyl)carbazole (DTC) as the electron-donating units. 3DPyM-pDTC, which is structurally nearly planar with a very small ΔE ST, shows higher color purity, horizontal ratio, and quantum yield than 2DPyM-mDTC, which has a more flexible structure. An electroluminescence device based on 3DPyM-pDTC as the dopant emitter can reach an extremely high external quantum efficiency of 31.9% with a pure blue emission. This work also demonstrates a way to design materials with a high portion of horizontal molecular orientation to realize a highly efficient pure-blue device based on TADF emitters.
Unusual decreases of water levels were consistently observed in 78% (= 42/54) of wells in the Choshuichi Alluvial Fan of central Taiwan about 250 days before the Chi-Chi earthquake (M = 7.6 on 20 ...September 1999) while possible factors of barometric pressure, earth tides, precipitation as well as artificial pumping were removed. Variations in groundwater levels measured on anomalous wells from 1 August 1997 to 19 September 1999, which covers the 250 day unusual decreases, were transferred into the frequency domain to unveil frequency characteristics associated with the Chi-Chi earthquake. Analytical results show that amplitudes at the frequency band between 0.02 day super(-1) and 0.04 day super(-1) generally maintained at the low stage and were apparently enhanced a few weeks before the Chi-Chi earthquake. Variations of amplitude at this particular frequency band were further examined along with other Taiwan earthquakes (M > 6) from 1 August 1997 to 31 December 2009. Features of the enhanced amplitudes at the frequency band are consistently observed prior to the other two earthquakes (the Rei-Li and Ming-Jian earthquakes) during the 12.5 yr study period. In addition, surface displacements recorded from GPS, which provides insights into understanding stress status in subsurface during the Chi-Chi earthquake, are also inspected. The result confirms that abnormal rise and fall changes in groundwater level yield an agreement with forward and backward surface displacements around the epicentre prior to the Chi-Chi earthquake.
Four 2-(styryl)triphenylene derivatives (TSs) were synthesized for deep-blue dopant materials. By using a pyrene-containing compound, DMPPP, as the host, the TS-doped devices exhibited significant ...delayed fluorescence via triplet-triplet annihilation, providing the highest quantum efficiency of 10.2% and a current efficiency of 12.3 cd A(-1).
Objectives
This study aims to assess the effectiveness of a multidomain intervention program on the change in functional status of hospitalized older adults.
Design
This single-arm, prospective, ...non-randomized interventional study investigates the efficacy of a multidomain interventional program including cognitive stimulation activity, simple exercises, frailty education, and nutrition counseling.
Setting and Participants
At a tertiary hospital in southern Taiwan, 352 eligible patients were sequentially enrolled. Included patients were aged ≥65 years (mean age, 79.6 ± 9.0 years; 62% male), scored 3–7 on the Clinical Frailty Scale (CFS), and were hospitalized in the geriatric acute ward.
Intervention
Those receiving standard care (physical rehabilitation and nutrition counseling) during January–July 2019 composed the historical control group. Those receiving the multidomain intervention during August–December 2019 composed the intervention group.
Measurements
The primary outcome was the change in activities of daily life (ADL) and frailty status, as assessed by Katz Index and Clinical Frailty Scale, with using the generalized estimating equation model. The length of hospital stay, medical costs, and re-admission rates were secondary outcomes.
Results
Participants undergoing intervention (n = 101; 27.9%) showed greater improvements in the ADL and CFS during hospitalization (ADL adjusted estimate, 0.61; 95% CI, 0.11–1.11; p = 0.02; CFS adjusted estimate, −1.11; 95% CI, −1.42–−0.80; p < 0.01), shorter length of hospital stay (adjusted estimate, -5.00; 95% CI, −7.99–−2.47; p < 0.01), lower medical costs (adjusted estimate, 0.58; 95% CI, 0.49–0.69; p < 0.01), and lower 30- and 90-day readmission rates (30-day adjusted OR aOR, 0.12; 95% CI, 0.27–0.50; p < 0.01; 60-day aOR, 0.04; 95% CI, 0.01–0.33; p < 0.01) than did controls.
Conclusions
Participation in the multidomain intervention program during hospitalization improved the functional status and decreased the hospital stay length, medical costs, and readmission rates of frail older people.
Prostate cancer (PC) can be related to increased systemic oxidative stress and dihydrotestosterone level, which are also reported to be involved in the pathogenesis of age-related macular ...degeneration (AMD). We conducted a cohort study to determine whether patients with PC have an increased risk of AMD.
Data were collected from the Taiwan Longitudinal Health Insurance Database for the 1999–2010 period. The study PC cohort comprised 22 084 patients aged ≥18 years with a first diagnosis of PC. The comparison cohort consisted of age-, occupation-, and urbanization level-matched patients at a ratio of 1 : 1. The primary outcome was the incidence of AMD, which was evaluated using Kaplan–Meier survival analysis and proportional hazards modeling.
The mean follow-up periods (standard deviation) for the patients with AMD in the age-, occupation-, and urbanization level-matched PC cohort and non-PC cohorts were 4.69 (2.90) and 5.51 (2.82) years. The mean age of the PC cohort was 73.9 years and that of the non-PC cohort was 73.2 years, with approximately 85.9% of the patients aged >65 years. The PC cohort had a higher risk of AMD than did the propensity score-matched non-PC cohort with an adjusted hazard ratio of 1.25 (95% confidence interval, 1.12–1.39). Compared with PC cohort receiving no injection hormone therapy, the PC cohort receiving injection hormone therapy had a lower risk of AMD (adjusted hazard ratio, 0.56; 95% confidence interval, 0.41–0.76).
PC is associated with an increased risk of AMD. Patients with PC receiving injected form of androgen deprivation therapy had a lower risk of AMD than patients with PC not receiving injected form of androgen-deprivation therapy.
