Associations between the use of red yeast rice preparations and adverse health outcomes: An umbrella review of meta-analyses of randomized controlled trials.

BACKGROUND: Red yeast rice (RYR), a natural lipid-lowering agent, is widely used in clinical practice. However, the existing meta-analyses concerning the safety of RYR preparations have yielded inconsistent results, and the credibility of the evidence has not been quantified. OBJECTIVE: This study was designed to evaluate the existing evidence and offer a comprehensive understanding of the associations between the use of RYR preparations and various adverse health outcomes. SEARCH STRATEGY: Seven literature databases were searched from inception to May 5, 2023, using medical subject headings and free-text terms (e.g., "red yeast rice," "Xuezhikang," and "Zhibitai"). INCLUSION CRITERIA: Meta-analyses that investigated and quantitatively estimated associations between the use of RYR preparations and adverse health outcomes were included in this study. DATA EXTRACTION AND ANALYSIS: Two researchers independently extracted data using a standardized data collection table; any disagreements were resolved by consulting a third researcher. Based on the participant, intervention, comparator and outcome (PICO) framework in each eligible meta-analysis, a series of unique associations between the use of RYR preparations and adverse health outcomes were determined. The associations' effect estimates were re-evaluated using random-effect models. RESULTS: Fifteen meta-analyses, comprising 186 (164 unique) randomized controlled trials, were identified. Based on A MeaSurement Tool to Assess Systematic Reviews version 2, 3 (20%) and 12 (80%) of these meta-analyses had low and critically low confidence, respectively. A total of 61 unique associations between the use of RYR preparations and adverse health outcomes were extracted from eligible meta-analyses. Based on the random-effect models, 10 (16.4%) associations indicated a significant protective effect of RYR preparations against adverse health outcomes, while 5 (8.2%) indicated an increased risk of adverse health outcomes related to uric acid, alanine transaminase and aspartate transaminase levels. The other 46 (75.4%) associations showed no significant difference between the use of RYR preparations and control treatments. Regarding the credibility of the evidence, 21 (34.4%), 34 (55.7%) and 6 (9.8%) associations showed moderate, low and very low credibility, respectively. CONCLUSION: The evidence examined in this study suggests that RYR preparations are safe; however, the credibility of the evidence was not high. Further high-quality evidence is required.

Magnolol alleviates pulmonary fibrosis inchronic obstructive pulmonary disease by targeting transient receptor potential vanilloid 4-ankyrin repeat domain.

Transient receptor potential vanilloid 4 (TRPV4) plays a role in regulating pulmonary fibrosis (PF). While several TRPV4 antagonists including magnolol (MAG), have been discovered, the mechanism of action is not fully understood. This study aimed to investigate the effect of MAG on alleviating fibrosis in chronic obstructive pulmonary disease (COPD) based on TRPV4, and to further analyze its mechanism of action on TRPV4. COPD was induced using cigarette smoke and LPS. The therapeutic effect of MAG on COPD-induced fibrosis was evaluated. TRPV4 was identified as the main target protein of MAG using target protein capture with MAG probe and drug affinity response target stability assay. The binding sites of MAG at TRPV4 were analyzed using molecular docking and small molecule interaction with TRPV4-ankyrin repeat domain (ARD). The effects of MAG on TRPV4 membrane distribution and channel activity were analyzed by co-immunoprecipitation, fluorescence co-localization, and living cell assay of calcium levels. By targeting TRPV4-ARD, MAG disrupted the binding between phosphatidylinositol 3 kinase γ and TRPV4, leading to hampered membrane distribution on fibroblasts. Additionally, MAG competitively impaired ATP binding to TRPV4-ARD, inhibiting TRPV4 channel opening activity. MAG effectively blocked the fibrotic process caused by mechanical or inflammatory signals, thus alleviating PF in COPD. Targeting TRPV4-ARD presents a novel treatment strategy for PF in COPD.

[Constituent elements and characteristics of ancient acupuncture and moxibustion prescriptions: taking migraine and headache as an example].

The basic constituent elements of ancient acupuncture prescriptions and moxibustion prescriptions for migraine and headache are extracted and summarized. The frequency and proportion of each element are counted and its characteristics are analyzed. The basic constituent elements of ancient acupuncture and moxibustion prescriptions includes five aspects: disease symptoms (main symptoms, concurrent symptoms, etiology and pathogenesis), disease type, acupuncture and moxibustion site (acupoint name, site name, meridian name), manipulation method (acupuncture method, reinforcing and reducing method, blood pricking method, moxibustion method) and curative effect. Acupuncture and moxibustion prescriptions are essential for recording the disease symptoms, while the acupuncture and moxibustion site and manipulation methods are the two core elements of ancient acupuncture and moxibustion prescriptions, which are also the premise to ensure that acupuncture and moxibustion prescriptions have good reference value.

A transition programme to enhance ICU new graduate nurses' professional identity and intention to remain employed: A pre- and postevaluation.

AIMS: To investigate the effect of a transition programme including cognitive-behaviour-based preceptorship intervention on ICU new graduate nurses' (NGNs)' professional identity and their intention to remain employed. DESIGN: One-arm pre- and post-test design followed the TREND Statement. METHODS: NGNs' professional identity and intention to remain employed were measured at baseline (T1), postintervention (1 month, T2) and 6-month follow-up (T3). RESULTS: Fifty-three NGNs completed the programme, and their professional identity score significantly increased postintervention [from 111.5 (SD = 16.72) at T1 to 114.2 (SD = 9.12) at T2, p < 0.05], but decreased at T3 [105.8 (SD = 9.44) compared with T1 and T2, p < 0.05]. There was no significant difference in ICU NGNs' intention of remain employed outcomes at three time points (p > 0.05). The transition programme was effective to improve ICU NGNs' professional identity immediately after the intervention, but the increment did not maintain at the 6-month follow-up.

Ligustilide attenuates airway remodeling in COPD mice by covalently binding to MH2 domain of Smad3 in pulmonary epithelium, disrupting the Smad3-SARA interaction.

Airway remodeling is one of the hallmarks of chronic obstructive pulmonary disease (COPD) and is closely related to the dysregulation of epithelial-mesenchymal transition (EMT). Smad3, an important transcriptional regulator responsible for transducing TGF-ß1 signals, is a promising target for EMT modulation. We found that ligustilide (Lig), a novel Smad3 covalent inhibitor, effectively inhibited airway remodeling in cigarette smoke (CS) combined with lipopolysaccharide (LPS)-induced COPD mice. Oral administration of an alkynyl-modified Lig probe was used to capture and trace target proteins in mouse lung tissue, revealing Smad3 in airway epithelium as a key target of Lig. Protein mass spectrometry and Smad3 mutation analysis via in-gel imaging indicated that the epoxidized metabolite of Lig covalently binds to the MH2 domain of Smad3 at Cys331/337. This irreversible bonding destroys the interaction of Smad3-SARA, prevents Smad3 phosphorylation activation, and subsequently suppresses the nuclear transfer of p-Smad3, the EMT process, and collagen deposition in TGF-ß1-stimulated BEAS-2B cells and COPD mice. These findings provide experimental support that Lig attenuates COPD by repressing airway remodeling which is attributed to its suppression on the activation of EMT process in the airway epithelium via targeting Smad3 and inhibiting the recruitment of the Smad3-SARA heterodimer in the TGF-ß1/Smad3 pathway.

Depressive Symptoms as a Mediator between Excessive Daytime Sleepiness and Suicidal Ideation among Chinese College Students.

The purpose of this study was to verify the mediating role of depressive symptoms between excessive daytime sleepiness and suicidal ideation in college students. Of the 6944 participants, 2609 (37.6%) were male and 4335 (62.4%) were female. College students with excessive daytime sleepiness (p < 0.001) and those with depressive symptoms (p < 0.001) were more likely to have suicidal ideation. Moreover, both excessive daytime sleepiness (ß = 0.14, 95% CI: 1.01−1.32) and depressive symptoms (ß = 1.47, 95% CI: 3.80−5.00) were associated with suicidal ideation. The effect size of the mediating role of depressive symptoms in excessive daytime sleepiness to suicidal ideation was 50.41% for the entire sample, 58.33% for males, and 42.98% for females. Depressive symptoms partially mediated the relationship between excessive daytime sleepiness and suicidal ideation. The timely assessment of depressive symptoms in college students with excessive daytime sleepiness, and intervention, may reduce their risk of suicidal ideation.

[Study on acupoint selection rules for headache based on the earliest recorded literature of ancient acupuncture prescriptions].

Through collecting the prescriptions for headache treated with acupuncture in Huangdi Neijing (Yellow Emperor's Inner Classic) till the Qing Dynasty, the literature traceability research is undertaken to determine the extant literature documents with the earliest recorded acupuncture prescriptions and identify the repeated ones in later generations; and then, the acupoint use frequency in the earliest recorded literature of acupuncture prescriptions in the extant documents and acupuncture treatment verses is analyzed separately. It is found that the most of acupoints of high use frequency are overlapped between such two kinds of literature. By integrating and classifying the same or similar contents of acupuncture prescription articles between headache and migraine, the common characteristics and acupoint selections are extracted, the regularity of acupoint selection is explored in view of etiology, complication and affected location, and the attributed fourteen meridians are analyzed statistically in terms of the acupoints in the earliest recorded prescriptions. Finally, the experience of ancient medical masters in acupuncture treatment for headache is obtained.

[Exploration of the main ancient medical books with the origin literature on acupuncture prescription and their evaluation method].

The paper reviews systematically the main ancient medical books with the origin literature included on acupuncture prescription. It is found that the origin literature with acupuncture prescription in successive dynasties mainly focuses on Qin-Han and Jin-Yuan Dynasties. In Jin, Tang and Song Dynasties, as well as Ming and Qing Dynasties, the literature mainly records the experience of medical masters in the previous dynasties. By taking "headache" and "retention of urine" as examples, the origins on the literature of clinical acupuncture prescription are explored, the distribution rules and characteristics are summarized. Moreover, the evidences and evaluation method of quality grading were explored on the ancient books with the origin literature of acupuncture prescription involved.

Azvudine is a thymus-homing anti-SARS-CoV-2 drug effective in treating COVID-19 patients.

Azvudine (FNC) is a nucleoside analog that inhibits HIV-1 RNA-dependent RNA polymerase (RdRp). Recently, we discovered FNC an agent against SARS-CoV-2, and have taken it into Phase III trial for COVID-19 patients. FNC monophosphate analog inhibited SARS-CoV-2 and HCoV-OC43 coronavirus with an EC50 between 1.2 and 4.3 µM, depending on viruses or cells, and selective index (SI) in 15-83 range. Oral administration of FNC in rats revealed a substantial thymus-homing feature, with FNC triphosphate (the active form) concentrated in the thymus and peripheral blood mononuclear cells (PBMC). Treating SARS-CoV-2 infected rhesus macaques with FNC (0.07 mg/kg, qd, orally) reduced viral load, recuperated the thymus, improved lymphocyte profiles, alleviated inflammation and organ damage, and lessened ground-glass opacities in chest X-ray. Single-cell sequencing suggested the promotion of thymus function by FNC. A randomized, single-arm clinical trial of FNC on compassionate use (n = 31) showed that oral FNC (5 mg, qd) cured all COVID-19 patients, with 100% viral ribonucleic acid negative conversion in 3.29 ± 2.22 days (range: 1-9 days) and 100% hospital discharge rate in 9.00 ± 4.93 days (range: 2-25 days). The side-effect of FNC is minor and transient dizziness and nausea in 16.12% (5/31) patients. Thus, FNC might cure COVID-19 through its anti-SARS-CoV-2 activity concentrated in the thymus, followed by promoted immunity.

Prolonged flushing and locking interval for totally implantable vascular access device: A systematic review and meta-analysis.

The objective of this systematic review is to evaluate the safety ad feasibility of the totally implantable vascular access devices (TIVADs) flushed more than 4 weeks. We searched the following electronic databases from the date their build-up to February 2020: PubMed, EMBASE, The Cochrane Central Register of Controlled Trials (CENTRAL), and CINAHL. The final selection resulted in 14 trials fulfilling the inclusion criteria and being included in our review. A pooled frequency of port-related late complications with longer flushing intervals (>4 weeks) was 8.0%, and the pooled frequency of occlusions, infections, and mechanical complications was 5.0%, 2.0%, and 3.0%, respectively. Then, we compared the frequency of port-related complications between standard and longer flushing intervals. There were no differences between the group's changes in the frequency of total late complications, occlusions, infections, and mechanical complications. This systematic review and meta-analysis demonstrates that longer flushing intervals for ports are safe. However, more prospective, power appropriated randomized trials are needed to explore the specific flushing time for ports.

Prevalence and Influencing Factors on Fatigue of First-line Nurses Combating with COVID-19 in China: A Descriptive Cross-Sectional Study.

Nurses' work-related fatigue has been recognized as a threat to nurse health and patient safety. The aim of this study was to assess the prevalence of fatigue among first-line nurses combating with COVID-19 in Wuhan, China, and to analyze its influencing factors on fatigue. A multi-center, descriptive, cross-sectional design with a convenience sample was used. The statistical population consisted of the first-line nurses in 7 tertiary general hospitals from March 3, 2020 to March 10, 2020 in Wuhan of China. A total of 2667 samples from 2768 contacted participants completed the investgation, with a response rate of 96.35%. Social-demographic questionnaire, work-related questionnaire, Fatigue Scale-14, Generalized Anxiety Disorder-7, Patient Health Questionnaire-9, and Chinese Perceived Stress Scale were used to conduct online survey. The descriptive statistic of nurses' social-demographic characteristics was conducted, and the related variables of work, anxiety, depression, perceived stress and fatigue were analyzed by t-tests, nonparametric test and Pearson's correlation analysis. The significant factors which resulted in nurses' fatigue were further analyzed by multiple linear regression analysis. The median score for the first-line nurses' fatigue in Wuhan was 4 (2, 8). The median score of physical and mental fatigue of them was 3 (1, 6) and 1 (0, 3) respectively. According to the scoring criteria, 35.06% nurses (n=935) of all participants were in the fatigue status, their median score of fatigue was 10 (8, 11), and the median score of physical and mental fatigue of them was 7 (5, 8) and 3 (2, 4) respectively. Multiple linear regression analysis revealed the participants in the risk groups of anxiety, depression and perceived stress had higher scores on physical and mental fatigue and the statistically significant positive correlation was observed between the variables and nurses' fatigue, the frequency of exercise and nurses' fatigue had a statistically significant negative correlation, and average daily working hours had a significantly positive correlation with nurses' fatigue, and the frequency of weekly night shift had a low positive correlation with nurses' fatigue (P<0.01). There was a moderate level of fatigue among the first-line nurses fighting against COVID-19 pandemic in Wuhan, China. Government and health authorities need to formulate and take effective intervention strategies according to the relevant risk factors, and undertake preventive measures aimed at reducing health hazards due to increased work-related fatigue among first-line nurses, and to enhance their health status and provide a safe occupational environment worldwide. Promoting both medical and nursing safety while combating with the pandemic currently is warranted.

Brainstem folding in an influenza child with Dandy-Walker variant.

BACKGROUND: Influenza in children is a major cause of morbidity and mortality worldwide. Nervous system diseases are a factor relating to increased mortality rate. However, reports of how these underlying diseases contribute to the death of children with influenza are rare. CASE SUMMARY: A 4-year-old-girl developed type A influenza-related encephalopathy (IAE) with seizures, acute disorder of consciousness, and intracranial hypertension (cerebrospinal fluid pressure: 250 mmH2O), and the Dandy-Walker variant was found by her first magnetic resonance imaging (MRI) when admission. Three days later, she suddenly presented anisocoria, acute pulmonary edema, and coma, and the later MRI found that she had compressed brainstem, oblongata "Z-like folding", and swelling bilateral basal ganglia. After admission, the patient were tested for routine and special biomarkers and underwent neuroimaging and neuroelectrophysiology examinations as well as Oseltamivir and intravenous immunogloblin treatments. When predicting that unstable intracranial structures detected by MRI might have disastrous consequences in the progression of IAE, she was transferred into the pediatric intensive care unit and underwent continuous assessment of clinical condition while she did not have instability of basic vital signs; at the same time, her parents were fully informed about the risk and prognosis. Although she was ultimately dead from brain stem failure, the parents expressed understanding and did not trigger a doctor-patient conflict. CONCLUSION: In case of finding an unstable intracranial structure, intensive care should be given to IAE patient and their clinical condition should be monitored continuously.

Diuretic Effect and Metabolomics Analysis of Crude and Salt-Processed Plantaginis Semen.

Plantaginis Semen (PS) is well recognized in traditional Chinese medicine (TCM) and health products. Crude PS (CPS) and salt-processed CPS (SPS) are the two most commonly used decoction pieces of PS, and are included in the 2020 edition of Chinese Pharmacopoeia. Although they all have multiple effects, the mechanisms for treating diseases are different and remain unclear, the processing mechanism of SPS is also indeterminate, which hinders their clinical application to a certain extent. In order to solve these problems and further develop PS in the clinical application. Here, we used saline-loaded model rats for experiments, and utilized an integrated approach consisting of pharmacological methods and metabolomics, which could assess the diuretic impact of CPS and SPS ethanol extracts on saline-loaded rats and elucidate the underlying mechanism. The results showed that CPS and SPS both produced increased urine volume excretion and urine electrolyte excretion, but the levels of aldosterone (ALD) and aquaporin 2 (AQP2) were decreased. And 30 differential metabolites such as linoleic acid, lysoPC(O-18:0), sphingosine-1-phosphate, lysoPC(18:0) were found, mainly involving three metabolic pathways. In conclusion, CPS and SPS both have a diuretic effect, and that of SPS is better. This work investigated the possible diuretic mechanisms of CPS and SPS which may also be the mechanism of PS for anti-hypertension. In addition, a holistic approach provided novel and helpful insights into the underlying processing mechanisms of TCM.

[Overview of evaluation methods on efficacy of acupuncture and moxibustion by ancient medical experts].

To sort out and summarize the evaluationmethods on the efficacy by acupuncture and moxibustion in ancient literature. The evaluation methods by ancient medical experts could be divided into two categories: one is according to the change of patient's conditions before and after treatment, including the subjective symptoms, the information getting from the four examination methods in TCM; the other is according to the characteristics of different interventions. For example, evaluating acupuncture by the "arrival of qi " "getting qi "; evaluating pricking collaterals-bloodletting therapy by the colour of blood; evaluating moxibustion by the skin colour and the feeling on the suppurated sore. This paper analyzed and discussed the particularity of acupuncture and moxibustion and the historical and technical reasons embodied in these methods, and then further expounded the enlightenment significance of these methods for clinical evaluation research for the contemporary acupuncture and moxibustion.

Altered profiles of fecal metabolites correlate with visceral hypersensitivity and may contribute to symptom severity of diarrhea-predominant irritable bowel syndrome.

BACKGROUND: Fecal metabolites are associated with gut visceral sensitivity, mucosal immune function and intestinal barrier function, all of which have critical roles in the pathogenesis of irritable bowel syndrome (IBS). However, the metabolic profile and pathophysiology of IBS are still unclear. We hypothesized that altered profiles of fecal metabolites might be involved in the pathogenesis of IBS with predominant diarrhea (IBS-D). AIM: To investigate the fecal metabolite composition and the role of metabolites in IBS-D pathophysiology. METHODS: Thirty IBS-D patients and 15 age- and sex-matched healthy controls (HCs) underwent clinical and psychological assessments, including the IBS Symptom Severity System (IBS-SSS), an Italian modified version of the Bowel Disease Questionnaire, the Bristol Stool Form Scale (BSFS), the Hospital Anxiety and Depression Scale, and the Visceral Sensitivity Index. Visceral sensitivity to rectal distension was tested using high-resolution manometry system by the same investigator. Fecal metabolites, including amino acids and organic acids, were measured by targeted metabolomics approaches. Correlation analyses between these parameters were performed. RESULTS: The patients presented with increased stool water content, more psychological symptoms and increased visceral hypersensitivity compared with the controls. In fecal metabolites, His [IBS-D: 0.0642 (0.0388, 0.1484), HC: 0.2636 (0.0780, 0.3966), P = 0.012], Ala [IBS-D: 0.5095 (0.2826, 0.9183), HC: 1.0118 (0.6135, 1.4335), P = 0.041], Tyr [IBS-D: 0.1024 (0.0173, 0.4527), HC: 0.5665 (0.2436, 1.3447), P = 0.018], Phe [IBS-D: 0.1511 (0.0775, 0.3248), HC: 0.3967 (0.1388, 0.7550), P = 0.028], and Trp [IBS-D: 0.0323 (0.0001, 0.0826), HC: 0.0834 (0.0170, 0.1759), P = 0.046] were decreased in IBS-D patients, but isohexanoate [IBS-D: 0.0127 (0.0060, 0.0246), HC: 0.0070 (0.0023, 0.0106), P = 0.028] was significantly increased. Only Tyr was mildly correlated with BSFS scores in all subjects (r = -0.347, P = 0.019). A possible potential biomarker panel was identified to correlate with IBS-SSS score (R 2 Adjusted = 0.693, P < 0.001). In this regression model, the levels of Tyr, Val, hexanoate, fumarate, and pyruvate were significantly associated with the symptom severity of IBS-D. Furthermore, visceral sensation, including abdominal pain and visceral hypersensitivity, was correlated with isovalerate, valerate and isohexanoate. CONCLUSION: Altered profiles of fecal metabolites may be one of the origins or exacerbating factors of symptoms in IBS-D via increasing visceral sensitivity.

Effect of Comprehensive Therapy based on Chinese Medicine Patterns on Self-Efficacy and Effectiveness Satisfaction in Chronic Obstructive Pulmonary Disease Patients.

OBJECTIVE: To evaluate the effect of comprehensive therapy based on Chinese medicine (CM) patterns on self-efficacy and satisfaction with its effectiveness in patients with chronic obstructive pulmonary disease (COPD). METHODS: A total of 216 patients were randomly divided into the trial group (n =108) and the control group (n=108) based on the stratified and block randomization design. Patients in the trial group were treated with conventional Western medicine combined with Bufei Jianpi Granules (), Bufei Yishen Granules (), and Yiqi Zishen Granules () according to the CM patterns respectively, and patients in the control group were treated with conventional Western medicine. The COPD Self-Efficacy Scale (CSES) and the Effectiveness Satisfaction Questionnaire for COPD (ESQ-COPD) were employed in a 6-month treatment and in further 6 month follow-up visit. RESULTS: Among the 216 patients, 191 patients (97 in the trial group and 94 in the control group) fully completed the study. After 12-month treatment and follow-up, the mean scores of the trial group all continued to increase over time, which were significantly higher than those of the control group (P <0.05), and the improvement in the following trial group domain: negative affect domain (12.13%), intense emotional arousal domain (12.21%), physical exertion domain (11.72%), weather/environmental domain (13.77%), behavioral risk domain (7.67%) and total score (10.65%). The trial group also exhibited significantly higher mean scores in the ESQ-COPD (P <0.05) and the improvement in the following domain: capacity for life and work domain (30.59%), clinical symptoms domain (53.52%), effect of therapy domain (35.95%), convenience of therapy domain (35.54%), and whole effect domain (52.47%). CONCLUSIONS: Bufei Jianpi Granules, Bufei Yishen Granules and Yiqi Zishen Granules can improve the self-efficacy and satisfaction of COPD patients.

Integrated traditional Chinese and conventional medicine in treatment of severe community-acquired pneumonia: study protocol for a randomized placebo-controlled trial.

BACKGROUND: Community-acquired pneumonia, especially severe community-acquired pneumonia (SCAP), remains the leading cause of death in the world. Despite advances in antimicrobial therapy, the mortality rates due to SCAP have not decreased significantly since antibiotics became routinely available. Traditional Chinese medicine (TCM) has been used for treating pneumonia for thousands of years. It is popular and widely practiced in Asia. In recent decades, evidence from both clinicians and patients suggests that TCM has some beneficial effect on SCAP. Thus, this study aims to compare the efficacy of a combination of a conventional drug and TCM to the conventional drug alone, to provide a scientific basis for clinical decisions. METHODS/DESIGN: A prospective, multi-center, single-blinded, double-dummy, and randomized controlled clinical trial is being conducted to test the therapeutic effects of a combination of conventional medicine and TCM versus conventional medicine in the treatment of SCAP. A total of 198 patients will be enrolled in this study, with 99 in each treatment group (combination group or conventional medicine group). The TCM will be administered twice daily for 28 days. All patients will be followed for 3 months. The primary outcome measure is treatment failure, which is defined as clinical deterioration. Secondary outcome measures are time to clinical stability, length of hospital stay, in-hospital mortality, SOFA questionnaire, quality of life and cost of treatment. DISCUSSION: It is hypothesized that the combination of a conventional drug and TCM will reduce treatment failure, time to clinical stability, length hospital of stays, and in-hospital mortality, and improve the quality of life of SCAP patients. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03185923 . Registered on 20 June 2017.

Anti-interleukin 5 Therapy for Eosinophilic Asthma: a Meta-analysis of Randomized Clinical Trials.

Recently, more and more clinical trials have been performed to evaluate the effects of anti-interleukin (IL)-5 antibodies in eosinophilic asthma. However, a confirm conclusion has not been well established. We therefore sought to conduct a meta-analysis to assess the overall efficacy and safety of anti-interleukin 5 treatments in eosinophilic asthma. RCTs of anti-interleukin 5 treatments in eosinophilic asthma published up to June 2016 in PubMed, Embase, Cochrane library databases, and CBM, which reported pulmonary functions, quality-of-life scores, asthmatic exacerbations, and adverse events were included. Fixed-effect models were used to calculate mean difference, relative risks (RR), and 95 % CIs. Twelve studies involving 3340 patients were identified. Pooled analysis revealed significant improvements in FEV1 (nine trials, 1935 subjects; MD = 0.12; 95 % CI, 0.08-0.16), and Asthma Quality-of-Life Questionnaire scores (five trials, 1334 subjects; MD = 0.23; 95 % CI, 0.13-0.34). Anti-interleukin 5 treatment was also associated with significantly decreased exacerbation risk than placebo (six trials, 875 subjects; RR = 0.52; 95 % CI, 0.46 to 0.59) and a lower incidence of adverse events (eight trials, 1754 subjects; RR = 0.93; 95 % CI, 0.89 to 0.97). Anti-interleukin 5 treatment is well tolerated and could significantly improve FEV1, quality of life, and reduced exacerbations risk in patients with eosinophilic asthma. Further trials are necessary to assess the baseline blood eosinophil count to identify the optimal patients of eosinophilic asthma that could benefit from anti-interleukin 5 therapy.

Trends in the Prevalence of Morbid Obesity among Children and Adolescents in Shandong, China, 1995-2014.

Background: Childhood obesity has increased dramatically during the past decades; however, data on the prevalence of morbid obesity is limited. The present study examined the prevalent trends in morbid obesity among children and adolescents during the past 19 years (1995-2014) in Shandong, China. Methods: Data for this study were obtained from five cross-sectional surveys (1995, 2000, 2005, 2010 and 2014) of schoolchildren in Shandong Province, China. A total of 41 500 students aged 7-18 years were included in this study. Body mass index cutoffs recommended by the International Obesity Task Force were used to define morbid obesity. Results: The prevalence of morbid obesity was increasing continuously during the past 19 years (1995-2014), from 0.25% for boys and 0.11% for girls in 1995 to 2.73% for boys and 1.29% for girls in 2014. Boys had higher prevalence of morbid obesity than girls (p<0.01). Regional socioeconomic status (SES) inequalities in morbid obesity were observed; children and adolescents from high SES district had a rapid increase in the prevalence of morbid obesity than their counterparts from moderate SES and low SES districts in the past 19 years. Conclusion: Although the current prevalence of morbid obesity was at a relatively low level, a continuous increasing trend was observed between 1995 and 2014. We should not relax our vigilance, and policymakers and experts should pay more attention to the monitoring and prevention of morbid obesity among children and adolescents in the future decades.

Isolation and molecular characterization of prevalent Fowl adenovirus strains in southwestern China during 2015-2016 for the development of a control strategy.

Fowl adenovirus (FAdV) has caused significant losses in chicken flocks throughout China in recent years. However, the current understanding of the genetic and pathogenic characteristics of the FAdV epidemic in southwestern China remains poorly understood. In this study, a total of 22 strains were isolated from liver samples of diseased chickens from farms in southwestern China. Phylogenetic analysis based on the hexon loop-1 gene showed that the 22 isolates were clustered into four distinct serotypes: FAdV serotype 4 (FAdV-4) (86.4%, 19/22), FAdV-2 (4.5%, 1/22), FAdV-8a (4.5%, 1/22), and FAdV-8b (4.5%, 1/22). FAdV-4 was the predominant serotype in southwestern China. Pathogenicity testing showed that the FAdV-4 serotype strain CH/GZXF/1602 and FAdV-8a strain CH/CQBS/1504 were pathogenic to chickens, with mortality rates reaching as high as 80% and 20%, respectively. The primary clinical feature observed following infection with strain CH/GZXF/1602 (FAdV-4) was hepatitis-hydropericardium syndrome, and that of strain CH/CQBS/1504 (FAdV-8a) was inclusion body hepatitis. Conversely, the FAdV-2 serotype strain CH/GZXF/1511 and FAdV-8b serotype strain CH/CQBS/1512 was not observed to be pathogenic in chickens. Then, CH/GZXF/1602 (FAdV-4) was selected for the preparation of an inactivated oil-emulsion vaccine. Immune studies on Partridge Shank broilers showed that a single dose immunization at 17 days of age could not only protect against homologous challenge with virulent FAdV-4 but also provided protection against clinical disease following challenge with the heterologous FAdV-8b virulent strain until 70 days of age. The characterization of newly prevalent FAdV strains provides a valuable reference for the development of an efficacious control strategy.
