Published: February 2021

Abstract

Background:
Ankylosing spondylitis (AS) is a common infammatory rheumatic disease that affects the axial skeleton. Traditional Chinese medicine (TCM) nonpharmacological interventions are gaining an increasing popularity for AS. Nevertheless, the evidence of efficacy and safety of random controlled trials (RCTs) remains controversial. This study aims to evaluate the efficacy and acceptability of different TCM nonpharmacological therapies by systematic review and network meta-analysis.

Methods:
According to the strategy, the authors will retrieve a total of 7 electronic databases by December 2020, including PubMed, the Cochrane Library, EMbase, China National Knowledge Infrastructure, China Biological Medicine, Chongqing VIP, and Wan-fang databases After a series of screening, 2 researchers will use Aggregate Data Drug Information System and Stata software to analyze the data extracted from the randomized controlled trials of TCM nonpharmacological interventions for AS. The primary outcome will be the improvement of Pain intensity and functional status/disability and the secondary outcomes will include lobal improvement, health-related quality of life, satisfaction with treatment, and adverse events. Both classical meta-analysis and network meta-analysis will be implemented to investigate direct and indirect evidences on this topic. The quality of the evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation instrument.

Results:
This study will provide a reliable evidence for the selection of TCM nonpharmacological therapies in the treatment of AS.

Conclusion:
This study will generate evidence for different TCM nonpharmacological therapies for AS and provide a decision-making reference for clinical research.

Ethics and dissemination:
This study does not require ethical approval. The results will be disseminated through a peer-reviewed publication.

Authors: Liu Yanjun , Guo Pengsen , Zhan Dafang , Fu Luo , Yu Jiahui , Yang Huawu 
Published: February 2021

Abstract

Introduction:
Morbid obesity (body mass index > 40 kg/m2) is a risk factor for the development of left ventricular systolic dysfunction (LVSD) and can complicate the management of LVSD. Bariatric surgery is increasingly recognized as a safe and effective way to achieve marked weight loss, but studies on improving LVSD populations are limited. We retrospectively analyzed the first case of the Asia-Pacific region with morbid obesity and left ventricular ejection fraction (LVEF) < 50% who underwent bariatric surgery at our medical center.

Patient concerns:
The patient was admitted to the hospital due to progressive weight gain for more than 10 years. The patient used to be in good health. One year before admission, the patient was hospitalized in another hospital due to shortness of breath. After the relevant examination, the patient was diagnosed with dilated cardiomyopathy.

Diagnosis:
The body mass index of the patient was 45.9 kg/m2, and the patient was diagnosed with morbid obesity. He was diagnosed with dilated cardiomyopathy and cardiac function class IV in another hospital. After completing a preoperative examination, the patient was diagnosed with hyperuricemia, hyperlipidemia, fatty liver disease and severe sleep apnea.

Interventions:
The patient successfully underwent laparoscopic sleeve gastrectomy plus jejunal bypass.

Outcomes:
Six months after the surgery, patient weight lost was 33.6 kg, and the LVEF increased from 31% to 55%. The cardiac function of the patient recovered from class IV to class I, and the patient's hyperuricemia, hyperlipidemia and sleep apnea were significantly improved.

Conclusion:
Bariatric surgery may be a safe and effective intervention for morbidly obese patients with LVSD. Bariatric surgery was associated with an improvement in LVEF. However, the specific mechanism still needs further study.

Abstract
To investigate whether chemical shift imaging (CSI) is useful for differentiating myelomatous infiltration from hematopoietic bone marrow (BM) and for quantitatively assessing disease severity.
In this retrospective study, spinal MRI, including a sagittal iterative decomposition of water and fat with echo asymmetry and least-squares estimation T2 fast spin-echo sequence, was performed on 76 myeloma patients (45 men, 67.0 ± 11.4 years; 31 women, 66.5 ± 11.0 years) and 30 control subjects (20 men, 67.0 ± 8.4 years; 10 women, 67.0 ± 9.2 years). The fat-signal fraction (FF) and mean signal dropout ratio (DR) were calculated from lumbar BM that contained no focal lesions. The BM plasma cell percentage (BMPC%) and serological data were obtained. As DR is highest when FF = 50%, the patients were divided into 2 groups: a water-dominant group (FF < 50%) and a fat-dominant group (FF > 50%).
Serum monoclonal protein (M protein), β2-microglobulin, and BMPC% were significantly higher in the water-dominant group than in the fat-dominant group. In the water-dominant group, DR correlated significantly with BMPC% and M protein, whereas in the control group, DR showed a weak correlation with age but no correlation with other clinical factors. No significant differences in any clinical data were seen between high and low DR.
CSI proved ineffective for differentiating myelomatous infiltration from hematopoietic BM. For myeloma patients with relatively high BM cellularity, a small signal drop on opposed-phase images indicated a higher tumor burden. For BM with relatively low cellularity, disease severity was not reflected by CSI.

Published: February 2021

Abstract
In humans, thrombocytopenic patients have increased incidence of post-hepatectomy liver failure (PHLF), but existing evidence is heterogeneous. Our objective was to determine if preoperative platelet count or antiplatelet drugs were associated with PHLF.
Patients who underwent hepatic resection in the University Hospitals of Geneva, Switzerland, from 01.12.2009 to 18.12.2018 were identified. Platelet count at day 0, postoperative days (POD) 1, 3, and 5 were retrieved. Occurrence of PHLF according to the ISGLS definition was determined. Logistic regression was performed to determine if platelet count or antiplatelet drug were predictors for PHLF.
Five hundred ninety seven patients were included. Eighty patients (17.8%) had a preoperative platelet count <150 (G/l) and 24 patients (5.3%) had a platelet count <100 (G/l). Thirty five patients (5.9%) were under antiplatelet drug. Platelet count significantly decreased at POD 1 and POD 3 when compared to preoperative platelet count (182 ± 71.61 (G/l) vs 212 ± 85.26 (G/l), P < .0001; 162 ± 68.5 (G/l) vs 212 ± 85.26 (G/l), P < .0001). At POD 5, post-operative platelet count did not significantly differ from its preoperative value. Forty three patients (11.2%) suffered from PHLF. Their platelet count was not significantly different than patients without PHLF (211 ± 89.7 (G/l) vs 211 ± 83.5 (G/l), P = .671). One patient with PHLF had a platelet count <100 (G/l) and 5 had a count <150 (G/l). Univariate logistic regression did not identify preoperative thrombocytopenia (<100 (G/l) or <150 (G/l)), postoperative thrombocytopenia, or the presence of antiagregant drug, as predictors of PHLF. We did not identify preoperative or postoperative thrombocytopenia as predictor of PHLF in a cohort of 597 patients.

Authors: Xu Lu , Chen Shuyan , Zhan Libin 
Published: February 2021

Abstract

Background:
Recently, the relationships between uncoupling protein-2 (UCP2) -866G/A (rs659366) and Ala55Val (rs660339) polymorphisms and the risk of type 2 diabetes mellitus (T2DM) have been explored considerably, but the results are greatly inconsistent. This meta-analysis was performed to further identify the association of UCP2 rs659366 and rs660339 with the risk of T2DM.

Methods:
Eligible studies were searched from PubMed, Embase, Cochrane Library, VIP database, Chinese National Knowledge Infrastructure, and Chinese WanFang database until March 8, 2020. The odds ratios with corresponding 95% confidence intervals (CIs), and P-values were used to assess the strength of the association.

Results:
A total of 26 studies were included in this study. UCP2 rs659366 was associated with the risk of T2DM in allele model (OR: 1.112, 95%CI: 1.009-1.224, P = 0.032), dominant model (OR: 1.189, 95%CI: 1.035–1.366, P = 0.014), and heterozygous model (OR: 1.177, 95%CI: 1.032–1.342, P = .015). A significantly increased risk of T2DM was detected in Asians by UCP2 rs659366 allele (OR: 1.132, 95%CI: 1.016–1.262, P = .025), dominant (OR: 1.218, 95%CI: 1.046–1.418, P = .011), homozygous (OR: 1.254, 95%CI: 1.022–1.540, P = .031) or heterozygous (OR: 1.198, 95%CI: 1.047–1.371, P = .009) models. There was no significant correlation between UCP2 rs660339 and the risk of T2DM (P>.05).

Conclusions:
The UCP2 rs65366 is significantly associated with the risk of T2DM, especially in Asian population, while no evidence is found between the UCP2 rs660339 and the susceptibility to T2DM.

Published: February 2021

Abstract
To evaluate the outcomes of the transjugular intrahepatic portosystemic shunt (TIPS) combined with AngioJet thrombectomy in patients with noncirrhotic acute portal vein (PV) thrombosis.
Retrospective analysis from January 2014 to March 2017, 23 patients underwent TIPS combined with AngioJet thrombectomy for acute PV thrombosis in noncirrhosis. The rates of technical success, the patency of the PV, liver function changes, and complications were evaluated.
Twenty-three patients underwent combined treatment, with a technical success rate of 100%. Twenty-four hours after treatment, PV thrombosis grade was improved significantly (P = .001). Before and after treatment, Albumin (gm/dl), aspartate transaminase (IU/l), alanine transaminase (IU/l), and platelets (109/L) were all significantly improved (P < .05). Minor complications include hematoma, hematuria, and hepatic encephalopathy. After 1 week of treatment, computed tomography scan revealed 8.7% (2/23) cases of hepatic envelope hematoma (thickness less than 2 cm). Hemoglobinuria occurred in 18/23 (78.3%) patients after treatment and returned to normal within 1 to 2 days. Two patients 2/23 (8.7%) had transient grade I encephalopathy after TIPS. The 1-year overall survival rate was 100% (23/23). No major complications during treatment in all patients
AngioJet thrombectomy via TIPS has a favorable short-term effect in clearing thrombus and alleviating symptoms in diffuse acute PVT. The long-term efficacy of this treatment needs to be further studied.

Published: February 2021

Abstract

Background
The evidence related to bleeding and thromboembolic events after transcatheter aortic valve replacement (TAVR) compared single antiplatelet therapy (SAPT) with dual antiplatelet therapy (DAPT) treatment are inconsistent. Moreover, there are some limitations such as small sample size and the risk of bias in existing studies. We will conduct a comprehensive systematic review and meta-analysis to explore the safety and efficacy of SAPT or DAPT after TAVR.

Methods
A comprehensive literature search of PubMed, EMBASE, The Cochrane Library, Cochrane Central Register of Controlled Trials will be searched to retrieve studies involving SAPT versus DAPT after TAVR. Two investigators will independently select studies, extract data, and assess the quality of the included study. Any disagreement will be resolved by the third investigator. The study will use a random-effects model to pool the results of all studies and use the relative risk and 95% confidence intervals to summarize individual trial outcomes and estimate pooled effect. The study will use the Grading of Recommendations Assessment, Development, and Evaluation to assess the certainty of evidence.

Results
This study will provide high-quality evidence for treatment of TAVR in terms of effectiveness and safety.

Conclusion
This systematic review aims to provide evidence for treatment of TAVR in different antiplatelet therapies.

Registration
The systematic review and meta-analysis is registered in the OSF REGISTRIES (10.17605/OSF.IO/Q42TE) international prospective register.
Intravenous pyogenic granuloma in the internal jugular vein
Authors: Yang Yuheng , Ye Xiaoping , Fu Binjie , Li Zhui , Feng Yangyang , Zhao Yu , Liu Hong 
Published: February 2021

Abstract

Rationale:
Intravenous pyogenic granuloma (IVPG) is a special type of pyogenic granuloma, and its preoperative diagnosis is difficult. We report a rare case of IVPG that develops in the lumen of the internal jugular vein (IJV). Here, we analyze the imaging characteristics of present case and summarize the imaging characteristics of previous reported cases.

Patient concerns:
A 44-year-old man who presented with a growth in the IJV without any symptoms.

Diagnoses:
A diagnosis of IVPG was made, based on the pathological examination after surgery.

Interventions:
The patient underwent surgery to excise the vein segment containing the neoplasm.

Outcomes:
The patient did not present with any complications in the postoperative follow-up period.

Lessons:
For clinician, IVPG's preoperative diagnosis is difficult. Although histopathology remains the gold standard for diagnosis, the combination of multiple types of imaging examinations is necessary to rule out the differential diagnoses of IVPG.

Abstract

Background:
Diabetic neurogenic bladder (DNB) is one of the common complications of diabetes mellitus, which has a high prevalence rate. Some research suggested that acupuncture can improve the clinical symptoms of diabetic neurogenic bladder patients, but there is no systematic review or meta-analysis to assess this therapy. Therefore, this study aims to explore the effectiveness and safety of acupuncture for patients with DNB.

Methods:
In this study, we will search for electronic databases including the Cochrane Library, Web of Science, PubMed, MEDLINE, EMBASE,
China National Knowledge Infrastructure (CNKI), Wan-Fang, and Baidu Scholar Database from inception to December 2020. We will select randomized controlled trials that have been published in English or Chinese related to acupuncture for DNB. Selection of study, extraction of data, and assessment of study quality will be performed independently by 2 researchers, and we will use Revman 5.3 software which is provided by Cochrane assistance network, to perform the data analysis.

Results:
This study will provide evidence of the effectiveness and safety of acupuncture for DNB.

Conclusion:
This study will clarify whether acupuncture is an effective treatment for DNB, and will also provide a reference for clinical practice and guidelines development.

Authors: Gil Hyun-Il , Yang Bumhee , Lee Taebum , Kim Min Yeong , Choi Hayoung , Yoo Hongseok , Kim Hojoong , Kwon O. Jung , Chung Sung Jun , Lee Hyun 
Published: February 2021

Abstract
Although Candida species can cause invasive fungal diseases, such as disseminated infection and pneumonia, they rarely cause tracheobronchitis, which is often fatal.
To identify the clinical characteristics of Candida tracheobronchitis, we retrospectively evaluated 8 patients who had pathologically proven Candida tracheobronchitis.
Their median age was 64 (range: 51–70) years and 5 were females. Three patients had solid cancers and 5 had hematological malignancies. We classified tracheobronchitis into localized and diffuse types. Of the 8 patients, 5 had localized and 3 had diffuse tracheobronchitis. While all patients with diffuse tracheobronchitis had predisposing risk factors for invasive fungal disease, such as prolonged corticosteroid use, recent use of nucleoside analogues, or recent neutropenia (<500/m3), only 2 of the 5 with localized tracheobronchitis had predisposing risk factors. Four of the 5 patients with localized tracheobronchitis had loco-regional bronchial mucosal damage (e.g., radiation or photodynamic therapy). Although all 8 patients ultimately died, some improved with or without antifungal treatment. Two of the 5 patients (1 with localized and the other with diffuse tracheobronchitis) who received antifungal agents improved after treatment, and 1 patient with localized tracheobronchitis who did not receive antifungal treatment improved spontaneously. Two of the 3 patients with diffuse tracheobronchitis did not respond to antifungal treatment.

Candida tracheobronchitis can present as both localized and diffuse types. While the former was influenced more by loco-regional mucosal damage, the latter was influenced more by the patient's immune status. The treatment outcomes were especially poor in patients with diffuse tracheobronchitis.

Abstract
MicroRNAs (miRNAs) play critical roles in carcinogenesis and development of cancers. In this study, we analyzed the eccentrically expressed miRNAs in head and neck squamous cell carcinoma (HNSCC) tissues based on the miRNA-Seq data of HNSCC patients available in the Cancer Genome Atlas database. Aberrant expression of 2589 miRNAs was detected in HNSCC tissues (1128 downregulated and 1461 upregulated). The differential expression levels of the miRNAs were further validated by analysis of 25 HNSCC samples and paired control tissues and compared with the Gene Expression Omnibus database to determine the candidate miRNAs. Quantitative reverse transcription polymerase chain reaction was used to compare the expression of these candidate miRNAs between 22 fresh HNSCC tissue samples and 11 control samples. In addition, the relationship between the expression of these candidate miRNAs and Tumor, Node, Metastases staging of HNSCC was analyzed. Compared with the expression in control tissues, the levels of hsa-miR-410-3p, hsa-miR-411-5p, hsa-miR-125b-2-3p, and hsa-miR-99a-3p were significantly lower in HNSCC. According to the Cancer Genome Atlas dataset analyzed, all 4 miRNAs were shown to inhibit tumor progression (T stage), positive lymph node metastasis (N stage), and distant metastasis (M stage) in HNSCC. Kyoto Encyclopedia of Genes and Genomes analysis showed that genes regulated by these 4 miRNAs were enriched in certain pathways, including the transforming growth factor-β signaling pathway and the Hippo pathway. Enriched gene ontology terms mainly included regulation of transcription, cell proliferation, and apoptosis, which are well-characterized functions of miRNAs. Moreover, all 4 miRNAs inhibited the progression of primary tumors (T stage) and metastasis of regional lymph nodes (N stage). The top 4 aberrantly expressed miRNAs identified in this study have great clinical value in developing strategies for early diagnosis and treatment of HNSCC. More intensive studies are required to elucidate the mechanism underlying the roles of these miRNAs in HNSCC.
