Relationship of symptom stress, care needs, social support, and meaning in life to quality of life in patients with heart failure from the acute to chronic stages: a longitudinal study. Health Qual Life Outcomes 2021; 19:252. [PMID: 34742311 PMCID: PMC8572479 DOI: 10.1186/s12955-021-01885-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 10/19/2021] [Indexed: 11/22/2022] Open
Abstract
Background Patients with heart failure (HF) experience continuous changes in symptom distress, care needs, social support, and meaning in life from acute decompensation to chronic phases. The longitudinal relationship between these four factors and quality of life (QOL) was not fully explored. Aims To simultaneously investigate the relationship between all factors and QOL from hospitalization to 6 months after discharge,
and the impact of the changes in these factors on QOL at different time points. Methods A longitudinal design with panel research (4 time points) was used. From January 2017 to December 2019, patients hospitalized due to acute decompensated HF were consecutively enrolled and followed up for 6 months. Patients were interviewed with questionnaires assessing symptom distress, care needs, social support, meaning in life and QOL at hospitalization and 1, 3 and 6 months after discharge. Results A total of 184 patients completed 6 months of follow-up. From baseline to 6 months, QOL continuously improved along with decreases in symptoms and care needs, but increases in social support and meaning in life. Better QOL was associated with younger age, higher education level, economic independence, less symptom distress and care needs, and stronger meaning in life (p < 0.05). Compared with hospitalization, decreases in care needs and increases in meaning in life at 1, 3 and 6 months were associated with an increase in physical QOL (p < 0.01). The decrease in care needs and increase in meaning in life at 3 months were associated with an increase in mental QOL (p < 0.05). The increase in social support at 6 months was associated with increases in both physical and mental QOL (p < 0.01). Changes in symptom distress were not correlated with changes in QOL from baseline to all time points. In the multivariable analysis, these findings were independent of age, educational level and economic status. Conclusions Although symptom distress is associated with QOL after acute decompensated HF, QOL cannot be improved only by improvement in symptoms. With differential duration of improvement in each factor, the integration of alleviation in care needs and strengthening in social support and meaning in life might provide additional benefits in QOL.

Measurement of the Absolute Branching Fraction of D_{s}^{+}→τ^{+}ν_{τ} via τ^{+}→e^{+}ν_{e}ν[over ¯]_{τ}. PHYSICAL REVIEW LETTERS 2021; 127:171801.

Abstract
Using a dataset of 6.32 fb^{-1} of e^{+}e^{-} annihilation data collected with the BESIII detector at center-of-mass energies between 4178 and 4226 MeV, we have measured the absolute branching fraction of the leptonic decay D_{s}^{+}→τ^{+}ν_{τ} via τ^{+}→e^{+}ν_{e}ν[over ¯]_{τ}, and find B_{D_{s}^{+}→τ^{+}ν_{τ}}=(5.27±0.10±0.12)×10^{-2}, where the first uncertainty is statistical and the second is systematic. The precision is improved by a factor of 2 compared to the previous best measurement. Combining with f_{D_{s}^{+}} from lattice quantum chromodynamics calculations or the |V_{cs}| from the CKMfitter group, we extract |V_{cs}|=0.978±0.009±0.012 and f_{D_{s}^{+}}=(251.1±2.4±3.0) MeV, respectively. Combining our result with the world averages of B_{D_{s}^{+}→τ^{+}ν_{τ}} and B_{D_{s}^{+}→μ^{+}ν_{μ}}, we obtain the ratio of the branching fractions B_{D_{s}^{+}→τ^{+}ν_{τ}}/B_{D_{s}^{+}→μ^{+}ν_{μ}}=9.72±0.37, which is consistent with the standard model prediction of lepton flavor universality.

Intervention-specific association of weight variability with major adverse cardiovascular events in overweight or obese adults with type 2 diabetes mellitus. Eur Heart J 2021.

Abstract
Abstract
Background
Weight variability is associated with cardiovascular outcomes in diabetic patients. However, the effect of higher weight variability caused by intensive lifestyle intervention (ILI) on cardiovascular outcomes in diabetic patients is not well established. We aimed to evaluate the intervention-specific association between weight variability with major adverse cardiovascular event (MACE) among overweight or obese adults with diabetes.
Methods
In 3,859 participants from the Action for Health in Diabetes (Look AHEAD) trial, multivariate-adjusted Cox regression models were used to evaluate the associations of weight variability measured by variability independent of the mean (VIM) with MACE and secondary outcomes in intensive lifestyle intervention (ILI) and diabetes support & education (DSE) arm, respectively.
Results
During a median follow-up of 9.6 years, 255 (12.9%) participants in the ILI arm and 247 (13.2%) participants in the DSE arm developed MACE. Participants with the highest quartile of weight variability (VIM Q4) experienced a 2.23-fold higher risk of MACE compared with the lowest quartile (VIM Q1) in the DSE arm (hazard ratio [HR] 2.23; 95% CI 1.51–3.30), but not the ILI arm (HR 1.05; 95% CI 0.73–1.50). Moreover, compared with the lowest weight variability (VIM Q1), participants with the highest weight variability (VIM Q4) were not associated with all secondary outcomes in the ILI arm (all P>0.05) but were associated with the higher risks of secondary cardiovascular composite outcome (HR 1.88; 95% CI 1.20–2.95), all-cause mortality (HR 3.19; 95% CI 1.75–5.82), and myocardial infarction (HR 1.95; 95% CI 1.12–3.37) in the DSE arm.
Conclusions
Among the overweight or obese individuals with type 2 diabetes mellitus, rising weight variability was independently associated with increased MACE risks in the DSE arm but not the ILI arm. Therefore, a guideline-recommended ILI strategy for weight loss should be adopted to improve cardiovascular outcomes without considering the effect of high weight variability.

Abstract
Using 2.93 fb^{-1} of e^{+}e^{-} collision data taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, the observation of the D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} semileptonic decay is presented. The statistical significance of the decay D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} is greater than 10σ. The branching fraction of D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} is measured to be (1.09±0.13_{-0.16}^{+0.09}±0.12)×10^{-3}. Here, the first uncertainty is statistical, the second is systematic, and the third originates from the assumed branching fraction of K_{1}(1270)^{-}→K^{-}π^{+}π^{-}. The fraction of longitudinal polarization in D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} is determined for the first time to be 0.50±0.19_{stat}±0.08_{syst}.

Abstract
The absolute branching fraction of Λ→pμ^{-}ν[over ¯]_{μ} is reported for the first time based on an e^{+}e^{-} annihilation sample of 10×10^{9} J/ψ events collected with the BESIII detector at sqrt[s]=3.097 GeV. The branching fraction is determined to be B(Λ→pμ^{-}ν[over ¯]_{μ})=[1.48±0.21(stat)±0.08(syst)]×10^{-4}, which is improved by about 30% in precision over the previous indirect measurements. Combining this result with the world average of B(Λ→pe^{-}ν[over ¯]_{e}), we obtain the ratio {[Γ(Λ→pμ^{-}ν[over ¯]_{μ})]/[Γ(Λ→pe^{-}ν[over ¯]_{e})]} to be 0.178±0.028, which agrees with the standard model prediction assuming lepton flavor universality. The asymmetry of the branching fractions of Λ→pμ^{-}ν[over ¯]_{μ} and Λ[over ¯]→p[over ¯]μ^{+}ν_{μ} is also determined, and no evidence for CP violation is found.

Abstract
BACKGROUND Infection is the most common non-cardiovascular cause of re-hospitalizations for heart failure patients. We therefore investigated the predictors of infection-related re-hospitalization (IRRH) in heart failure patients and its impact on long-term survival. METHODS AND RESULTS We prospectively recruited 622 patients after the index hospitalization for decompensated heart fail with primary endpoints of IRRH and all-cause mortality. During follow-up of 3.9 ± 2.7 years, IRRHs occurred in 104 (16.7%) patients. Of the 104 patients who experienced IRRHs, the time from the index hospitalization to IRRH was 1.0 (interquartile range: 0.4-2.6) years. Independent predictors of IRRH were age (hazard ratio: 1.02, 95% confidence interval: 1.01-1.04), diabetes mellitus (2.12, 1.42-3.17), not taking angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (1.67, 1.01-2.78), needing maintenance therapy with a loop diuretic (2.10, 1.36-3.26), hemoglobin levels (0.87, 0.79-0.96), and estimated glomerular filtration rates (eGFRs) (0.99, 0.98-0.99). IRRH independently predicted all-cause mortality (1.99, 1.32-2.98) after adjusting for age, body mass index, New York Heart Association functional class, chronic obstructive pulmonary disease, brain natriuretic peptide, hemoglobin, and eGFR. The increased risk of death associated with IRRHs was predominantly for lower respiratory tract infections (3.71, 2.28-6.04), urogenital tract infections (2.83, 1.32-6.10), and sepsis (3.26, 1.20-8.85). CONCLUSION IRRHs in patients discharged for acute decompensated heart fail independently predicted worse long-term survival. We further identified independent predictors of IRRHs. These findings warrant future studies for tackling IRRH.

Abstract
We report a study of the processes of e^{+}e^{-}→K^{+}D_{s}^{-}D^{*0} and K^{+}D_{s}^{*-}D^{0} based on e^{+}e^{-} annihilation samples collected with the BESIII detector operating at BEPCII at five center-of-mass energies ranging from 4.628 to 4.698 GeV with a total integrated luminosity of 3.7 fb^{-1}. An excess of events over the known contributions of the conventional charmed mesons is observed near the D_{s}^{-}D^{*0} and D_{s}^{*-}D^{0} mass thresholds in the K^{+} recoil-mass spectrum for events collected at sqrt[s]=4.681 GeV. The structure matches a mass-dependent-width Breit-Wigner line shape, whose pole mass and width are determined as (3982.5_{-2.6}^{+1.8}±2.1) MeV/c^{2} and (12.8_{-4.4}^{+5.3}±3.0) MeV, respectively. The first uncertainties are statistical and the second are systematic. The significance of the resonance hypothesis is estimated to be 5.3 σ over the contributions only from the conventional charmed mesons. This is the first candidate for a charged hidden-charm tetraquark with strangeness, decaying into D_{s}^{-}D^{*0} and D_{s}^{*-}D^{0}. However, the properties of the excess need further exploration with more statistics.

Abstract
Objective: To investigate the clinical outcomes of different treatment options on singleton short cervix and its influence factors. Methods: Totally 435 cases of singleton pregnancies who were diagnosed with short cervix (≤25 mm) between 12 to 33+6 gestational weeks in Peking University First Hospital from January 2018 to December 2018 were enrolled, including 21 cases with cervical length <10 mm, 414 cases with cervical length between 10 to 25 mm. The onset time was <24 gestational weeks in 106 cases, while 104 cases were at 24-29+6 gestational weeks and 225 cases of ≥30 gestational weeks. Gestational outcomes including delivery before 37 weeks, delivery before 34 weeks, neonatal birth weight (NBW) and adverse neonatal outcome (ANO) were compared among three treatment groups: rest group, progesterone group and cerclage group. Influence factors were also investigated. Results: (1) The incidence of short cervix in pregnancy was 7.07% (435/6 155), while 106 cases were at <24 gestational weeks (1.72%, 106/6 155), 104 cases (1.69%, 104/6 155) at 24-29+6 gestational weeks and 225 cases (3.66%, 225/6 155) at ≥30 gestational weeks. (2) In the group of cervical length <10 mm, rate of delivery before 37 and 34 weeks were 62% (13/21) and 57% (12/21) respectively. One case of progesterone treatment underwent miscarriage. Compared with rest group (n=8), delivery weeks [28.5 (25.0-40.0) vs 37.0 (28.0-40.0), P=0.020] and NBW [1 245 g (630-3 830 g) vs 2 648 g (1 560-3 830 g), P=0.028] were higher in cerclage group (n=9), while ANO was not statistically different (P>0.05). (3) In the group of cervical length ≥10 mm before 24 gestational weeks, the delivery weeks, incidence of delivery before 34 weeks, adjusted incidence of delivery before 37 weeks, NBW and ANO were not statistically different (P>0.05) among rest group (n=36), progesterone group (n=26) and cerclage group (n=34). In vitro fertilization (OR=11.97, 95%CI: 1.88-76.44, P=0.009), infection (OR=46.03, 95%CI: 5.12-413.58, P=0.001), sludge on sonography (OR=9.87, 95%CI: 1.69-57.60, P=0.011) and history of short cervix (OR=7.24, 95%CI: 1.04-50.24, P=0.045) were independent risk factors of preterm birth. (4) In the group of cervical length ≥10 mm and gestational weeks between 24-29+6, the delivery weeks, incidence of delivery before 37 weeks, incidence of delivery before 34 weeks, NBW and ANO were not statistically different (P>0.05) among rest group (n=52), progesterone group (n=34) and cerclage group (n=9). Infection was an independent risk factor of preterm birth (OR=56.40, 95%CI: 4.67-680.61, P=0.002). (5) Outcomes of 223 cases were relatively good in the group of cervical length ≥10 mm beyond 30 gestational weeks. The incidence of delivery before 34 weeks was 6.3% (14/223). The delivery weeks, incidence of delivery before 37 and 34 weeks, NBW and ANO were not statistically different (P>0.05) among 3 groups. Infection (OR=10.91, 95%CI: 2.21-53.96, P=0.003) and history of preterm birth (OR=8.63, 95%CI: 1.25-59.65, P=0.029) were independent risk factors of preterm birth. Conclusions: Short cervix is a common complication of pregnancy. Cervical cerclage is related with better outcome for patients with cervical length <10 mm. Neither progesterone nor cervical cerclage improves pregnancy outcome for >10 mm cervical length patients comparing with rest. Infection, sludge, in vitro fertilization, history of short cervix and history of preterm birth are independent risk factors of preterm birth in short cervix pregnancies.

Abstract
Asthma is an inflammatory pulmonary illness that plagues infants and young children. We carried out this investigation to examine the role of long noncoding RNA (lncRNA) RNA component of mitochondrial RNA processing endoribonuclease (RMRP) in an asthmatic mouse model induced by ovalbumin (OVA) and human airway smooth muscle cells (ASMCs). Eight-week-old mice were sensitized with OVA to simulate pediatric asthma. The expression patterns of RMRP, microRNA-206 (miR-206) and C-C motif ligand 2 (CCL2) in pulmonary tissues were evaluated by qPCR. In addition, the concentrations of interleukin (IL)-4, IL-5 and IL-13 cytokines in bronchoalveolar lavage fluid were detected by ELISA. The expression of RMRP and CCL2 was elevated, while miR-206 was reduced in OVA-induced mice. Our findings indicated that administration of RMRP overexpression in ASMCs increased the levels of biomarkers in asthma. RMRP functioned as a sponge for miR-206 to upregulate CCL2 expression. Blockade of the TGF-β/Smad2 signaling pathway in ASMCs overexpressing RMRP suppressed the inflammatory cytokines and cell viability, while enhancing apoptosis. The RMRP/miR-206/CCL2 regulatory axis is implicated in the occurrence of pediatric asthma.

Abstract
BACKGROUND Meaning in life serves as a protective mechanism for coping with persistent, often distressful symptoms in patients with heart failure. However, meaning in life and its associated factors are not adequately explored in patients after acute hospitalisation for heart failure. AIMS To explore the associated factors of meaning in life in patients with heart failure from acute hospitalisation to 3 months post-discharge. METHODS A total of 103 hospitalised patients with heart failure in Northern Taiwan were recruited using a longitudinal study design and interviewed with structured questionnaires including meaning in life, symptom distress, care needs, and social support at hospitalisation, 1 month and 3 months post-discharge. RESULTS A total of 83 patients completed the 3 months follow-up. The presence of meaning in life significantly increased from hospitalisation to 3 months post-discharge. Decreases in care needs (B=-0.10, P=0.020) and social support (B=-0.18, P=0.016) from hospitalisation to 3 months post-discharge were significantly associated with an increase in the presence of meaning in life, while a decrease in social support was associated with an increase in the search for meaning in life (B=-0.17, P=0.034). CONCLUSION Care needs and social support were pivotal factors for developing meaning in life for patients with heart failure. Assessments of care needs and social support might help strengthen their meaning in life.

Abstract
Elevated phenylalanine has been observed in patients with advanced heart failure (HF) and in community cohorts at risk of HF, and has been shown to have prognostic value. This study aimed to explore the factors associated with elevated phenylalanine in HF patients. Mass spectrometry was performed on blood from 669 participants, including 75 normal controls and 594 HF patients (stages A, B, and C). We measured phenylalanine and associated degradation products on the catecholamine pathway, C-reactive protein, valerylcarnitine, methionine sulfoxide, estimated glomerular filtration rate (eGFR), and B-type natriuretic peptide. Longitudinal analysis was conducted on 61 stage C HF patients who had recovered systolic function after 1 year. Phenylalanine and tyrosine levels increased from normal through stages A, B and C. Cross-sectional analysis in patients at stage C showed that phenylalanine levels were related to total bilirubin, eGFR, valerylcarnitine, methionine sulfoxide, C-reactive protein, and male gender. Longitudinal analysis in the patients at stage C with recovered systolic function after 1 year revealed that phenylalanine, tyrosine, methionine sulfoxide, total bilirubin, and C-reactive protein levels significantly decreased from baseline to 12 months. Based on a generalized estimating equations analysis model with time interaction considered, the only significant factor associated with changes in phenylalanine was changes in C-reactive protein concentrations from baseline to 12 months [B (coefficient) = 0.81, P < 0.001] after adjusting for methionine sulfoxide and total bilirubin levels. In conclusion, phenylalanine levels respond sensitively to HF improvement. Our findings suggest that inflammation plays a pivotal role in the elevation of phenylalanine levels in patients with HF.

Abstract
Impaired fatty acid metabolism is associated with heart failure (HF) prognosis. However, specific changes in acylcarnitine profiles and their potential clinical value have not been well explored in patients recovering from acute decompensation.This study recruited 79 HF patients hospitalized because of acute decompensation with a left ventricular ejection fraction (LVEF) of < 40% and 51 normal controls. Patients were dichotomized into two groups, namely, the "improved (IMP) " and the "non-improved (NIMP) " groups, as defined by the changes in LVEF from baseline to 12 months after discharge. Mass spectrometry was used to quantify the acylcarnitine concentrations at baseline and 6 and 12 months after discharge. The IMP and NIMP groups contained 42 and 37 patients, respectively. At baseline, HF patients had higher plasma concentrations of specific long-, medium-, and short-chain acylcarnitines compared to normal controls. From baseline to 12 months post-discharge, the IMP group showed significant decreases in long- and short-chain acylcarnitine concentrations, but significant increases in medium-chain acylcarnitines. In the NIMP group, none of the acylcarnitines significantly decreased, and significant increases were noted in long-, medium-, and short-chain acylcarnitines. Generalized estimating equations demonstrated that nine acylcarnitines could discriminate the IMP group from the NIMP group, including three long-chain (C18:1, C16, and C16:1) and six short-chain acylcarnitines (C5, C5-OH, C4, C4:1-DC, C3, and C2). After adjusting for age, the six short-chain acylcarnitines remained significant. Changes in short-chain acylcarnitine profiles are independently associated with the improvement in cardiac systolic function after acute decompensation.

Abstract
PURPOSE Myocardial oxygenation imaging is a field-of-interest but its clinical utility largely unexplored. We aimed to investigate the myocardial oxygenation status via T2* imaging and compared with the left ventricular ejection fraction (LVEF) in chronic heart failure (HF) patients after hospitalization. Also, we sought to compare the differences in myocardial oxygenation status among patients with ischemic HF, non-ischemic HF and controls. METHODS We prospectively enrolled 60 participants, comprising 20 HF patients with LVEF ≥ 50 % as the improved ejection fraction (HFIEF) group, 20 H F patients with ejection fraction <50 % as the reduced ejection fraction (HFREF) group, and 20 controls. Patients were also dichotomized into ischemic and non-ischemic subgroups. T2* values were compared across the study groups, and correlated with LVEF, myocardial scar distribution and quantity. RESULTS T2* values positively correlated with LVEF and were significantly lower in the HFREF group as compared with both HFIEF and controls (20.06 vs. 24.23; 20.06 vs. 26.32, respectively, both p < 0.05). Lower T2* values were observed in the HFREF group than the HFIEF group and the ischemic subgroup than the non-ischemic subgroup. No significant correlation existed between T2* value and the myocardial scar amounts in ischemic territory. CONCLUSIONS Oxygen-sensitive T2* measurements showed correlation with LVEF and ischemic etiology in chronic heart failure patients, while the ischemic HFREF patients appeared to be more vulnerable to myocardial oxygen reduction than other groups. T2* measurements may be clinically feasible in monitoring heart failure via myocardial oxygenation and lay the foundation for future studies in prediction heart failure recovery.

Abstract
Huntington's disease (HD) is caused by Huntingtin (Htt) gene mutation resulting in the loss of striatal GABAergic neurons and motor functional deficits. We report here an in vivo cell conversion technology to reprogram striatal astrocytes into GABAergic neurons in both R6/2 and YAC128 HD mouse models through AAV-mediated ectopic expression of NeuroD1 and Dlx2 transcription factors. We found that the astrocyte-to-neuron (AtN) conversion rate reached 80% in the striatum and >50% of the converted neurons were DARPP32+ medium spiny neurons. The striatal astrocyte-converted neurons showed action potentials and synaptic events, and projected their axons to the targeted globus pallidus and substantia nigra in a time-dependent manner. Behavioral analyses found that NeuroD1 and Dlx2-treated R6/2 mice showed a significant extension of life span and improvement of motor functions. This study demonstrates that in vivo AtN conversion may be a disease-modifying gene therapy to treat HD and other neurodegenerative disorders.

Left Ventricular Function and Myocardial Triglyceride Content on 3T Cardiac MR Predict Major Cardiovascular Adverse Events and Readmission in Patients Hospitalized with Acute Heart Failure. J Clin Med 2020; 9:jcm9010169.

Abstract
Background: This prospective study was designed to investigate whether myocardial triglyceride (TG) content from proton magnetic resonance spectroscopy (MRS) and left ventricular (LV) function parameters from cardiovascular magnetic resonance imaging (CMR) can serve as imaging biomarkers in predicting future major cardiovascular adverse events (MACE) and readmission in patients who had been hospitalized for acute heart failure (HF). Methods: Patients who were discharged after hospitalization for acute HF were prospectively enrolled. On a 3.0 T MR scanner, myocardial TG contents were measured using MRS, and LV parameters (function and mass) were evaluated using cine. The occurrence of MACE and the HF-related readmission served as the endpoints. Independent predictors were identified using univariate and multivariable Cox proportional hazard regression analyses. Results: A total of 133 patients (mean age, 52.4 years) were enrolled. The mean duration of follow-up in surviving patients was 775 days. Baseline LV functional parameters—including ejection fraction, LV end-diastolic volume, LV end-diastolic volume index (LVEDVI), and LV end-systolic volume (p < 0.0001 for all), and myocardial mass (p = 0.010)—were significantly associated with MACE. Multivariable analysis revealed that LVEDVI was the independent predictor for MACE, while myocardial mass was the independent predictor for 3- and 12-month readmission. Myocardial TG content (lipid resonances δ 1.6 ppm) was significantly associated with readmission in patients with ischemic heart disease. Conclusions: LVEDVI and myocardial mass are potential imaging biomarkers that independently predict MACE and readmission, respectively, in patients discharged after hospitalization for acute HF. Myocardial TG predicts readmission in patients with a history of ischemic heart disease.

Abstract
A new technology called in vivo glia-to-neuron conversion has emerged in recent years as a promising next generation therapy for neural regeneration and repair. This is achieved through reprogramming endogenous glial cells into neurons in the central nervous system through ectopically expressing neural transcriptional factors in glial cells. Previous studies have been focusing on glial cells in the grey matter such as the cortex and striatum, but whether glial cells in the white matter can be reprogrammed or not is unknown. To address this fundamental question, we express NeuroD1 in the astrocytes of both grey matter (cortex and striatum) and white matter (corpus callosum) to investigate the conversion efficiency, neuronal subtypes, and electrophysiological features of the converted neurons. We discover that NeuroD1 can efficiently reprogram the astrocytes in the grey matter into functional neurons, but the astrocytes in the white matter are much resistant to neuronal reprogramming. The converted neurons from cortical and striatal astrocytes are composed of both glutamatergic and GABAergic neurons, capable of firing action potentials and having spontaneous synaptic activities. In contrast, the few astrocyte-converted neurons in the white matter are rather immature with rare synaptic events. These results provide novel insights into the differential reprogramming capability between the astrocytes in the grey matter versus the white matter, and highlight the impact of regional astrocytes as well as microenvironment on the outcome of glia-to-neuron conversion. Since human brain has large volume of white matter, this study will provide important guidance for future development of in vivo glia-to-neuron conversion technology into potential clinical therapies. Experimental protocols in this study were approved by the Laboratory Animal Ethics Committee of Jinan University (approval No. IACUC-20180321-03) on March 21, 2018.

Abstract
Objective:To investigate the prevalence and state of allergic rhinitis, asthma, eczema, allergic conjunctivitis, and food allergy of students in primary and middle schools of Foshan, and to analyze the characteristics of each disease and correlation of the five diseases, in order to provide epidemiology evidence for management of allergic diseases. Method:Ten primary schools and 10 junior middle schools were sampled from 5 districts of Foshan, then students in grade one and grade seven from sampled schools were investigated by electronic questionnaire method formulated by the International Study of Asthma and Allergies in Childhood and the Europrevall Project Commission. Students and their parents answered and uploaded electronic questionnaires with the consent of parents, and then team members collected and analyzed uploaded data. Result:Four thousand one hundred and sixty-six effective questionnaires were collected, and the response rate was 95.77%. During the five districts, 13.97%, 2.01%, 29.29%, 5.19%, and 7.28% of the respondents in grade one had previously diagnosed with allergic rhinitis, asthma, eczema, allergic conjunctivitis, and food allergy respectively, and the correspondent rates in grade seven were 15.99%, 2.89%, 16.73%, 2.46%, and 6.97%. The prevalence rates of the five diseases in boys were higher than that in girls in both two grades. 67.27% students with asthma kept coughing and wheezing in the last 12 months, and 24.85% non-asthma students had the same respiratory symptoms. The most common allergenic food were shrimp and crabs, followed by milk and milk products, eggs, and shellfish. Cutaneous symptoms and oral allergy symptoms were predominant clinical manifestations in all students with food allergy. The prevalence of the above allergic diseases of children with atopic family history was higher than that of children without family history, and the prevalence of the 5 diseases of children living in city was higher than that of children living in rural areas. The prevalence rate of asthma of children with allergic rhinitis in both grades was higher than that of children without allergic rhinitis, and the same happened to children with eczema, allergic conjunctivitis, and food allergy. Conclusion:Prevalence rates of allergic rhinitis and asthma in primary and middle school students of Foshan increased as children grew, while the prevalence rates of eczema, allergic conjunctivitis and food allergy decreased with age. The most common allergenic food were shrimp and crabs, milk and milk products, and eggs. 67.27% students with asthma had poor respiratory control in the last 12 months. The prevalence of allergic diseases of children living in city and with atopic family history was higher than that of children living in rural areas and without family history. Students with allergic conjunctivitis, food allergy, allergic rhinitis and eczema had high risk of asthma.

Abstract
Background The BODE index is a multidimensional grading system for predicting the prognoses of patients with chronic obstructive pulmonary disease (COPD). This study investigated whether an amino acids-based metabolic profile developed for heart failure patients (including histidine, ornithine, phenylalanine, and leucine) could identify COPD patients and further discriminates COPD patients in advanced BODE stages. Methods Ultra-performance liquid chromatography was performed on 119 participants, including 75 COPD patients at different BODE stages and 44 normal controls. Albumin, pre-albumin, transferrin, high sensitivity C-reactive protein, and hand grip strength were also measured. Receiver operating characteristic curves and area under curves were used for estimation. Results The BODE points in our patients were 3.29 [95% confidence interval (CI) = 2.74-3.85]. Compared to normal controls, COPD patients had lower leucine but higher ornithine levels. A COPD score, developed based on leucine and ornithine, significantly discriminated COPD from normal controls [odds ratio (OR) = 2.71, 95% CI = 1.83-4.04, p <0.001]. A COPD score of ≥ 3.00 had an OR of 15.58 (95% CI = 5.96-40.73, p <0.001). In COPD patients from BODE 1 to BODE 4, the levels of histidine, ornithine and phenylalanine increased significantly. In multivariable analysis, histidine and phenylalanine were independently able to distinguish BODE stages 3 and 4 from BODE 1 and were adopted to develop a metabolic score. Metabolic scores identified patients at BODE 3 and 4 (OR = 2.74, 95% CI =1.41-5.29, p = 0.003) better than hand grip strength, high sensitive C-reactive protein, albumin, pre-albumin, and transferrin value. A metabolic score of ≥9.53 significantly discriminated BODE 3 and 4 from BODE 1 and 2 (OR = 8.56, 95% CI = 2.77-26.39, p <0.001). Conclusion Amino acid-based COPD score and metabolic score discriminate COPD patients from normal controls, and identify patients in advanced stages of COPD.

Abstract
Objective: To evaluate the clinical efficacy and safety of intralymphatic immunotherapy with cervical lymph node injection for allergic rhinitis. Method: A retrospective analysis of 81 patients with allergic rhinitis(AR) who had received specific immunotherapy with cervical lymph node injection in 2016 in the first people's Hospital of Foshan was conducted. The neck lymph node immunotherapy under the guidance of color Doppler ultrasound consisted of three sessions, and in each session 50 Tu(Arog) was delivered. The scores of nasal and ocular symptoms, drug score and adverse reactions during treatment were recorded before and after treatment, and the efficacy and safety were observed. Result: Before treatment, the nasal symptoms score of 81 AR cases of mite allergy was 7.00±1.65. After 1,2 and 3 sessions of cervical lymph node immune therapy and 1 year after completion of treatment, the nasal symptom scores were 4.37±1.88, 4.26±1.80, 4.22±1.80, and 4.09±2.10,respectively, which were significantly lower than that before treatment(P<0.01). The quality of life score was 53.68±9.28 before treatment, which decreased to 23.01±13.28 one year after treatment, and the difference was statistically significant(P<0.01). The drug score was 3.27±1.17 before treatment, which decreased to 1.00±1.05 1 years after treatment, and the difference was statistically significant(P<0.01). During treatment and 1-year follow-up, only 8 cases had mild local reactions, and no systemic adverse reactions occurred. Conclusion: Cervical lymph node injection specific immunotherapy can significantly relieve the symptoms of dust mite allergic rhinitis. The treatment is effective and safe, and greatly shortens the duration of immune treatment.

Abstract
Objective: To investigate the therapeutic effects and mechanisms of interleukin-10 (IL-10) gene-modified dendritic cells (DC-IL-10) in mice with liver fibrosis. Methods: DC-IL-10 was constructed in vitro, the phenotype and function of which were evaluated by flow cytometry. BALB/c mice were treated with intraperitoneal injection of carbon tetrachloride (CCl4) to establish liver fibrotic model. DC-IL-10 was administrated via tail vein. Animals were divided into 4 groups including normal dendritic cell(DC) control, liver fibrosis only, negative lentiviral transfection DC (DC-mock) and DC-IL-10. Liver function, cytokine secretion, T lymphocyte differentiation and liver histomorphology were tested. Real-time PCR and western blot were used to analyze the effect of DC-IL-10 on Wnt/β-catenin signaling pathway and its role in liver fibrosis. Results: When compared with DC control and DC-mock, the expression of DC-IL-10 surface stimulating molecules (major histocompatibity complex-Ⅱ, CD(80), CD(86)) were significantly decreased (F=14.708, 22.503, 12.595, respectively, all P<0.05), and DC-IL-10 significantly inhibited T lymphocyte proliferation (F=50.295, P<0.05). When compared with liver fibrosis group, serum alanine aminotransferase and aspartate transaminase were decreased in DC-IL-10 treated group (all P<0.05), other parameters including inflammatory factors (tumor necrosis factor α, IL-6, IL-1β) reduced (all P <0.05), the proportion of regulatory T cells (Treg) increased (F=6.742, P<0.05), pathological damage improved, the expression of Wnt3a, α-SMA and β-catenin mRNA and protein significantly reduced in DC-IL-10 treatment group (all P<0.001) . Conclusions: DC-IL-10 induces elevation of Treg for immune tolerance, as well as inhibition of inflammatory response, block of Wnt/β-catenin signaling pathway, which translates into improvement of liver fibrosis.

Abstract
In heart failure (HF), metabolic disturbances represent functional perturbations in peripheral tissues and also predict patient outcomes. This study developed a simplified essential amino acid-based profile and tested whether it could improve prognostication. Plasma essential amino acids and lipidomics were measured on 1084 participants. The initial cohort included 94 normal controls and 599 patients hospitalized due to acute/decompensated HF. The validation cohort included 391 HF patients. Patients were followed for composite events (death/HF related re-hospitalization) and were categorized into three groups: high risk type 1 (leucine ≥145 μM and phenylalanine ≥ 88.9 μM), high risk type 2 (leucine < 81.2 μM), and low risk (other). Types 1 and 2 were associated with higher event rates [hazard ratio (95% confidence intervals) = 1.88 (1.27-2.79) and 7.71 (4.97-11.9), respectively, p < 0.001]. Compared to the low-risk group, both types of high-risk patients were older and had lower blood pressure and estimated glomerular filtration rates, but higher B-type natriuretic peptides (BNP). In addition, type 1 was associated with more incompletely metabolized lipids in the blood; type 2 patients had lower body mass indexes, rates of using guideline-based medications, and levels of cholesterol, hemoglobin, and albumin. The prognostic value of types 1 and 2 remained significant after adjusting for age, BNP and other risk factors. The value of using high-risk types for prognosis was confirmed in the validation cohort. In conclusion, simplified essential amino acid-based profiling identified two high-risk populations and provided metabolic information and prognostic value additive to traditional risk factors.

Abstract
Objective: To investigate the incidence rate of transjugular intrahepatic portosystemic shunt (TIPS) complications in the treatment of cirrhotic portal hypertension, and analyze the cause of complication to management methods. Methods: Data of 116 patients obtained from Zhongnan Hospital of Wuhan University were retrospectively analyzed. Portal venous pressure, routine blood test, coagulation test, liver and kidney function test, ammonia blood test, imaging and endoscopy reports were collected before and after procedure. The incidence rate of hepatic encephalopathy, gastrointestinal bleeding, ascites and shunt dysfunctions were observed. Data were expressed as mean ± Standard deviation and analyzed by t-test. A chi-squared test was used for comparison between categorical variables. Results: The success rate of TIPS operation was 97.41% (113/116). Two patients underwent prompt TIPS procedure due to active bleeding. Bleeding was successfully stopped. Portal venous pressure of 113 patients decreased from (42.73 ± 7.64) cmH(2)O to (24.92 ± 7.60) cmH(2)O, and the difference was statistically significant (P < 0.01). Twenty cases were of hepatic encephalopathy. Preoperative level of Child-pugh class C patients was more susceptible to hepatic encephalopathy within 3 months after procedure than class A and B. After TIPS procedure, there were 22 cases of gastrointestinal bleeding, 18 cases of shunt dysfunctions and 26 cases of disease related death. Conclusion: Rational patient selection strategies can effectively reduce portal venous pressure, incidence of hepatic encephalopathy, improve mid-and long-term therapeutic effects, and provide opportunities for liver transplantation.

Abstract
BACKGROUND Heart failure is a complex syndrome that causes substantial functional impairment and poor outcomes. Although multidisciplinary disease management programmes are effective, the role of additional outpatient-based exercise training and the effects of multidisciplinary disease management programmes for patients with contraindications to exercise training are unclear. OBJECTIVES To compare the effects of the multidisciplinary disease management programme with and without exercise training on heart failure-related rehospitalization, disease knowledge, and functional capacity. DESIGN Secondary analysis of a randomized controlled trial. PARTICIPANTS AND SETTING Data for 212 patients hospitalized for heart failure at a local teaching hospital in Taiwan were analysed. METHODS Patients' data were assigned to three groups: control (n = 71), multidisciplinary disease management programme without exercise training (n = 70) or multidisciplinary disease management programme with exercise training (n = 71). The multidisciplinary disease management programme included comprehensive assessments, individualized education, optimizing medications, pre-scheduled clinic visits, and encouraging regular physical activity at home. Outpatient-based exercise training was performed only in the multidisciplinary disease management programme with exercise training group. The control and the multidisciplinary disease management programme without exercise training groups were further divided into subgroups with and without contraindications to exercise training. Patients were followed up monthly for heart failure-related rehospitalizations for 1 year. Cox proportional hazard models and Kaplan-Meier analyses were used to identify the significant predictors of heart failure-related rehospitalizations. A generalized estimation equation model was used to analyse the secondary outcomes, including disease knowledge and 6-min walking distance at baseline and 6 and 12 months after discharge. RESULTS At 12 months after discharge, the multidisciplinary disease management programme with and without exercise training groups had significantly lower heart failure-related rehospitalization rates and better disease knowledge compared with the control group (p < 0.01). Only the multidisciplinary disease management programme with exercise training group had a significant improvement in 6-min walking distance (p < 0.05). For patients with contraindications to exercise, the multidisciplinary disease management programme significantly reduced heart failure-related rehospitalization rates at 12 months after discharge (p < 0.05). For those without contraindications, the event-lowering effect was only noted for the multidisciplinary disease management programme with exercise training group (p < 0.05). CONCLUSIONS Outpatient-based exercise training is recommended to be incorporated into multidisciplinary disease management programmes for patients without exercise contraindications to improve disease outcomes and functional capacity. For patients with contraindications to exercise, a multidisciplinary disease management programme is recommended to improve patient outcomes.

Abstract
Nanowalkers take either inchworm (IW) or hand-over-hand (HOH) gait. The IW nanowalkers are advantageous over HOH ones in force generation, processivity and high-density integration, though both gaits occur in intracellular nanowalkers from biology. Artificial IW nanowalkers have been realized or proposed, but all rely on different 'head' and 'tail' to gain an adventitious direction. Here we report an inherently unidirectional IW nanowalker that is a biped with two identical legs (i.e., indistinguishable 'head' and 'tail'). This walker is made of DNA, and driven by a light-powered G-quadruplex engine. The directional inchworm motion is confirmed by operating the walker on a DNA duplex track that is designed to show a distinctive fluorescence pattern for IW walkers as compared to HOH ones. Interestingly, this walker exhibits stride-controlled IW-to-HOH gait switch and direction reversal when the track's periodic binding sites have wider and wider separation. The results altogether present an integrated mechanism for implementing nanowalkers of different gaits and directions on molecular tracks, optical potentials or even solid-state surfaces.

Abstract
Artificial molecular walkers beyond burn-bridge designs are important for nanotechnology, but their systematic development remains difficult. Herein, we have reported a new rationally designed DNA walker-track system and experimentally verified a previously proposed general expulsion regime for implementing non-burn-bridge nanowalkers. The DNA walker has an optically powered engine motif that reversibly extends and contracts the walker via a quadruplex-duplex conformational change. The walker's extension is an energy-absorbing and force-generating process, which drives the walker's leg dissociation off-track in a piston-like expulsion stroke. The unzipping-shearing asymmetry provides the expulsion stroke a bias, which decides the direction of the walker. Moreover, three candidate walkers of different sizes were fabricated. Fluorescence motility experiments indicated two of them as successful walkers and revealed a distinctive size dependence that was expected for these expulsive walkers, but was not observed in previously reported walkers. This study identifies unique technical requirements for expulsive nanowalkers. The present DNA design is readily adapted for making similar walkers from other molecules since the unzipping-shearing asymmetry is common.
