Abstract
Rheumatoid arthritis (RA) is associated with an increased risk of venous thromboembolism (VTE) occurrence. In this work, we assessed the incidence and predictive factors of VTE in our “real-life” cohort of RA patients. To contextualize our results, we reviewed the available literature about this topic.
We performed a retrospective analysis of prospectively followed-up patients with RA attending our Rheumatologic Clinic between January 2010 and December 2020. Each patient was investigated for VTE occurrence. Incident cases were reported as incidence proportion and incidence rate per 1000 person-years at risk. Possible predictive factors were also exploited by regression analyses. Available literature about this topic was also assessed.
In this evaluation, 347 consecutive patients without previous evidence of VTE, attending our Rheumatologic Clinic from 2010 to 2020, were studied. In our “real-life” cohort, the incidence proportion of VTE was 3.7% (2.7–4.7%) and considering over 1654 person-years, an incidence rate of 7.8 × 1000 (2.5–11.7). Exploratively assessing predictive factors in our cohort, older age (hazard ratio [HR] 1.07, 95% confidence interval [CI] 1.01–1.14, p = .015), higher body mass index (HR 1.37, 95% CI 1.04–1.80, P = .026), and longer disease duration (HR 1.11, 95% CI 1.03–1.20, P = .006) resulted to be significant predictors of VTE occurrence during the follow-up.
In our “real-life” cohort, VTE burden has been suggested in patients with RA. Comparing our results with previous data derived from randomized controlled trials and administrative data, some different findings were retrieved about incidence of VTE. Assessing predictive factors, older age, higher body mass index, and longer disease duration resulted to be significant predictors of VTE occurrence during the follow-up. Taking together these observations, a further evaluation of this issue on specific designed studies is needed to provide more generalizable results to the daily clinical practice.
Efficacy and tolerability of doxazosin gastro-intestinal therapeutic system versus tamsulosin in patients with lower urinary tract symptoms associated with benign prostatic hyperplasia
Authors: Guo Jianming , Tang Rong 
Published: August 2021

Abstract

Background:
Alpha1-adrenoceptor antagonists (α1-blockers) are first-line drugs for the treatment of lower urinary tract symptoms associated with benign prostate hyperplasia (BPH). Doxazosin gastrointestinal therapeutic system (GITS) and tamsulosin belong to the 2 most frequently prescribed α1-blockers. This systematic review and meta-analysis was performed to compare the efficacy and tolerability of these 2 α1-blockers.

Methods:
A systematic review of published randomized controlled trials in English or Chinese language was performed using the PubMed, EMBASE, Cochrane Library, CNKI, Wanfang, and Vip databases. After data extraction and quality assessment, the meta-analysis was performed to compare clinical parameters (International Prostate Symptom Score [IPSS] total [IPSS-T], storage [IPSS-S], voiding [IPSS-V], maximum urine flow [Qmax], and postvoid residual) and adverse events (AEs) that changed after first drug intake.

Results:
After the screening, 8 eligible randomized controlled trials with 1316 patients were identified. Doxazosin-GITS showed a significantly higher efficacy compared with tamsulosin (IPSS-T P < .001, IPSS-S P < .001, and IPSS-V P < .001). There were no significant differences between the 2 drugs for changes in Qmax (P = .477) or postvoid residual (P = .739). The overall AEs were significantly lower in the doxazosin-GITS group (risk ratio: 0.77; 95% CI: 0.54–1.08; P = .036). However, dizziness (P = .387), headache (P = .745), asthenia (P = .693), postural hypotension (P = .114), and retrograde ejaculation (P = .187) were similar between the 2 groups.

Conclusions:
This meta-analysis indicates that doxazosin-GITS has significantly higher efficacy and lower AEs than tamsulosin in patients with lower urinary tract symptoms/benign prostate hyperplasia.

Abstract
To explore the predictive value of preoperative serum squamous cell carcinoma antigen (SCC-Ag) level for lymph node metastasis (LNM), particularly, in patients surgically treated for early-stage cervical squamous cell carcinoma.
We enrolled 162 patients with cervical squamous cell carcinoma stages IB to IIA following the International Federation of Gynecology and Obstetrics (FIGO) 2009 classification. The patients had previously undergone radical surgery. Correlation of the SCC-Ag level with clinicopathological features and the predictive value of SCC-Ag for LNM were analyzed.
High preoperative SCC-Ag level was correlated with FIGO stage (P = .001), tumor diameter >4 cm (P < .001), stromal infiltration (P < .001), LNM (P < .001) and lymphovascular space invasion (LVSI), (P = .045). However, it was not correlated with age, histological differentiation, parametrial involvement, and positive vaginal margin (P > .05). Univariate analysis revealed that FIGO stage (P = .015), tumor diameter (P = .044), stromal infiltration (χ2 = 10.436, P = .005), SCC-Ag ≧ 2.75 ng/mL (χ2 = 14.339, P < .001), LVSI (χ2 = 12.866, P
< .001), parametrial involvement (χ2 = 13.784, P < .001) were correlated with LNM, but not with age, histological differentiation, and positive vaginal margin. Moreover, multivariate analysis demonstrated that SCC-Ag ≧2.75 ng/mL (P = .011, OR = 3.287) and LVSI (P = .009, OR = 7.559) were independent factors affecting LNM. The area under the receiver operator characteristic curve of SCC-Ag was 0.703 (P < .001), while 2.75 ng/mL was the best cutoff value for predicting LNM. The sensitivity and specificity of diagnosis were 69.4% and 65.9%, respectively.
High SCC-Ag level was revealed to be an independent risk factor for the prognosis of squamous carcinoma of the cervix before an operation. Besides, SCC-Ag (2.75 ng/mL) can be utilized as a potential marker to predict LNM in early stage cervical cancer before an operation.

Abstract
There is an increasing concern about the impact of bracing on the quality of life (QoL) of patients with adolescent idiopathic scoliosis (AIS). However, up to now, few multidimensional questionnaires on this impact are available in China. This study aimed to evaluate the reliability and validity of the Chinese version of Brace Questionnaire (C-BrQ).
The BrQ was translated from Greek into Chinese with proper cross-cultural adaptation.
An observational, cross-sectional study in Chinese patients with AIS was conducted to measure the temporal stability of C-BrQ using the intraclass correlation coefficient (ICC). The effects of ceiling and floor were evaluated and the reliability was verified by examining the internal consistency. The C-BrQ domains were compared with the domains in Chinese version of Scoliosis Research Society-22 Outcomes Questionnaire (C-SRS-22) using Pearson correlation coefficient to assess the concurrent validity.
A total of 208 patients were included in the study. The results of test-retest reliability for each dimension of C-BrQ were desirable. The floor or ceiling effects were not demonstrated in the C-BrQ and C-SRS-22. Satisfactory internal consistency was found in all the C-BrQ domains. Most C-BrQ and C-SRS-22 domains showed satisfactory correlation coefficients, except when vitality and school activity in C-BrQ were compared with self-image, mental health, and management satisfaction in C-SRS -22, respectively.
C-BrQ is reliable in evaluating the QoL of AIS patients receiving brace treatment.
Cerebral vasospasm resulted in “stent shortening” after pipeline assisted coil embolization for blood blister aneurysms

Published: August 2021

Abstract
Blood blister aneurysms (BBAs) are intracranial arterial lesions appearing in nonbranching sites of the supraclinoid internal carotid artery as well as the basilar artery. Endovascular treatment of BBAs is still not well established because of the rarity of these lesions. We report incidences of BBAs with associated vasospasms. Treatment of the BBAs and associate vasospasms with single Pipeline Flex embolization device (PLED) assisted coiling resulted in seemly shorting of the PLEDs in 3 patients.
A retrospective analysis of patients with BBAs who were treated with single PLED assisted coiling from July 2018 to October 2019 was conducted. Patients’ ethnic and medical records, aneurysmal characteristics, intraoperative-rupture, cerebral vasospasm (CVS), postprocedure contrast filling, follow-up imaging, and results were analyzed. Neurological examination at baseline and outcome based on modified Rankin scale (mRS) at discharge as well as follow-ups were also documented.
Six patients consisting of 5 females and 1 male, with a mean age of 48.3 years (range from 34–67) were identified during our analysis. All the BBAs were located in nonbranching site of supra-clinoidal segment of internal carotid artery with a mean neck width of 4.5 mm and mean aneurysm size of 4.23 mm. PLED assisted coiling's were performed in all of them. CVS was observed in 3 patients while 1 patient had an intraoperative-rupture of the BBA. Postprocedure contrast filling was still present in 1 patient. All the patients had good outcomes with discharge and follow-up mRS scores ≤ 2 except 1 patient with mRS score = 3 with aphasia.
PLED assisted endovascular coiling is very safe and efficient in treating patients with BBAs. Resolution of CVSs after treatment made the PLEDs seemly shorter. Furthermore, a combination of arterial lengthening after gaining their tensile strength back and radical expansion of the PLED could account for the shortening.

Published: August 2021

Abstract

Background:
We sought to synthesize the evidence about aerobic exercise intervention during pulmonary rehabilitation, and to further explore the difference in rehabilitation effects between water and land-based aerobic exercise. This review's purpose is to provide a basis by which practitioners and therapists can select and create appropriate therapeutic programs.

Methods:
Data of randomized and quasi-randomized controlled trials comparing training group (TG, aerobic exercise in water or land) and control group (CG, usual care) in chronic obstructive pulmonary disease (COPD) patients (January 1, 2000–December 28, 2019) were obtained from the Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure, and Wanfang databases. Two researchers independently reviewed the literature, extracted the data, and evaluated the quality of the literature. Review Manager software (Rev Man 5.3; Cochrane, London, UK) was used for meta-analysis. The rehabilitation effect of water- or land based aerobic exercise was evaluated by subgroup analysis. The proposed systematic review details were registered in PROSPERO (CRD 42020168331).

Results:
Eighteen studies (1311 cases of COPD) were included. Meta-analysis results show that compared with the control group, the dyspnea level and functional and endurance exercise capacity in COPD patients were significantly improved after aerobic exercise (P < .05), but there was no significant change in lung function (P > .05). Compared with land-based aerobic exercise, water-based aerobic exercise significantly improved the endurance exercise capacity in COPD patients (mean difference [MD]: 270.18, 95% CI: 74.61–465.75).

Conclusion:
Medium to high-quality evidence shows that aerobic exercise can effectively improve dyspnea and exercise capacity in COPD patients. Compared with land-based aerobic exercise, water-based aerobic exercise had a significant additional effect in improving the endurance exercise capacity of COPD patients.

Authors: Kong Meng , Zhou Tao , Xiang Bo 
Published: August 2021

Abstract
Hirschsprung disease (HD) is a common form of digestive tract malformation in children. However, the pathogenesis of HD is not very clear. This study aimed to investigate the expression of slit guidance ligand 2 (Slit2) and roundabout 1 (Robo1) in patients with HD.
From January 2018 to January 2019, 30 colon specimens from children with HD undergoing surgical resection at the Department of Surgery in Qilu Children's Hospital of Shandong University were obtained. These specimens were divided into the normal segment group, the transitional segment group and the spastic segment group. Immunohistochemical staining, Western blotting, and real-time polymerase chain reaction were used to measure the expression of Slit2 and Robo1 in the intestinal walls of normal, transitional, and spastic segments.
Immunohistochemical staining and Western blot analyses showed high levels of the Slit2 and Robo1 proteins in normal ganglion cells in children with HD, lower levels in transitional ganglion cells, and no expression in spastic segments, with significant differences between groups (P < .05). Similarly, the real-time polymerase chain reaction results were consistent with the Western blot analysis results.
The expression of Slit2 and Robo1 decreases significantly in the spastic segment of the intestinal tract in patients with HD.

Published: August 2021

Abstract

Background
There are various treatments for facial nerve palsy, and research into this topic is ongoing. In the present study, we carried out bibliometric and visualized analyses to identify the trends of research into facial nerve palsy treatment.

Methods
To identify articles, the SCOPUS database was searched for articles published from its inception to December 27, 2020. The search was conducted twice, with Search 1 investigating general treatment trends and Search 2 narrowing the scope to complementary and alternative treatment. The extracted keywords were analyzed using the Visualization Of Similarities (VOS) viewer. Through analysis of keywords, research hotspots in the treatment of facial nerve palsy were identified.

Results
A total of 1609 and 223 articles were identified in Searches 1 and 2, respectively. The number of articles published each year showed a tendency to increase, and most of the studies were only conducted in a few countries. In terms of subject area, “medicine” was overwhelmingly the most common(77.6%). Based on the analysis of 316 keywords in Search1, “medication treatment,” and “complementary and alternative treatment” were the hotspots of research.

Conclusion
This study provides the overall trends of facial nerve palsy treatment. To date, research on medication treatment has been main focus, and antiviral use among medication treatment and complementary and alternative treatment has emerged in recent years.
Establishing a critical pathway for Korean medical management of lumbar disc herniation
Authors: Kim Jung-hyun , Goo Bonhyuk , Seo Byung-kwan 
Published: August 2021

Abstract
A modified Delphi method was used to establish a consensus. Stakeholders and experts were invited to participate in the expert panel. Best practice statements and decision-making questionnaires were distributed to the panel. Panel members were asked to mark “Strongly disagree” to “Strongly agree” after a series of statements over several rounds until either a consensus was reached or the decision-making method was deemed unsuitable for reaching a consensus.
The most common cause of lumbar pain is intervertebral degeneration, which leads to degenerative disc disease and lumbar disc herniation. There is a lack of unanimity regarding appropriate patient protocols and rehabilitation expectations for Korean medical care. The long-term viability of Korean medical treatment, further adoption in the institutional setting, and specific patient outcomes are contingent on the existence of appropriate Korean medical programs.
A Korean medical expert panel of 17 practitioners employed a modified Delphi method to achieve consensus on Korean medical care for lumbar disc herniation. The panel first reviewed the literature and guidelines relevant to Korean medical treatment for lumbar disc herniation. The panel members considered questionnaires intended to determine “standardized” Korean medical care recommendations for patients with a wide range of symptoms of lumbar disc herniation. Each panel member participated in a round of voting, which was followed by an opinion-collecting session online. Consensus was defined as a ≥75% agreement among the respondents.
In the first round, 144 questionnaires across 5 domains were administered to the expert panels. After reviewing the responses and open-ended comments collected in the first round, the authors modified the questionnaires to 53 items and proceeded. In round 2, consensus was achieved in all 53 survey questions. The final treatment pathway comprised a standardized and comprehensive care approach for lumbar disc herniations in 4 types of medical institutions.
This study identified a core set of evidence- and consensus-based principles that are essential to a comprehensive model of care, incorporating identification, referral, and management of patients with lumbar disc herniation.

Abstract
The prognostic impact of atrial fibrillation (AF) in patients with severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection has not been well evaluated. We estimated the prognostic implications of AF in SARS-CoV-2 confirmed patients.
The OpenData4Covid19 (https://hira-covid19.net) project is a global research collaboration on coronavirus disease (COVID-19), hosted by the Ministry of Health and Welfare of Korea and the Health Insurance Review and Assessment Service of Korea. This dataset comprises all COVID-19-tested patients and their individual histories of medical service use from January 1, 2017 to May 15, 2020. All patients >19 years with confirmed SARS-CoV-2 infection were included. The primary endpoint was a composite of death and intensive care unit admission.
In total, 7162 adults with SARS-CoV-2 infection were included in this study. The prevalence of AF was 1.8% (n = 130). Patients with AF had unfavorable characteristics, such as older age and higher prevalence of comorbidities. The primary endpoint was more common in patients with AF than in those without (33.9% vs 12.9%, P < .001). In the multivariable model, age (odds ratio [OR]: 1.035, 95% confidence interval [CI]: 1.030–1.040), female sex (OR: 0.618, 95% CI: 0.535–0.713), diabetes (OR: 1.341, 95% CI: 1.093–1.580), and chronic kidney disease (OR: 2.714, 95% CI: 1.541–4.777) were associated with the primary endpoint. However, AF was not an independent predictor of the primary endpoint (OR: 1.402, 95% CI: 0.932–2.108).
Patients with AF and concomitant SARS-CoV-2 infection had more comorbidities and a worse prognosis. However, an independent association between AF and adverse clinical outcomes was not evident.
Effect of physical therapy intervention on thickness and ratio of the sternocleidomastoid muscle and head rotation angle in infants with congenital muscular torticollis
Authors: Song Seonghyeok , Hwang Wonjeong , Lee Seungwon 
Published: August 2021

Abstract

Background:
Early diagnosis as well as treatment is important in management of congenital muscular torticollis (CMT). The purpose of this study was to find an effective physical therapy modality to improve the sternocleidomastoid (SCM) muscle thickness, the ratio of the SCM muscle thickness on the affected side to that on the non-affected side (A/N ratio), and head rotation in infant under 3 months of age diagnosed with CMT.

Methods and analysis:
A single-blind, randomized clinical trial was conducted. Participants were assigned in one of the 3 study groups through randomization. The treatment was performed 3 times a week for 30 minutes until the head tilt was ≤5 degrees. Group 1 was treated by handling for active or active-assist movement, group 2 was treated with passive stretching, and group 3 was treated with thermotherapy. For general characteristics, a χ
2 test and 1-way analysis of variance were used. Intragroup differences were analyzed using a paired t test, and intergroup differences were analyzed using an age-adjusted analysis of covariance.

Results:
After the intervention, there was no significant difference between groups in terms of SCM thickness on the affected side and A/N ratio (P > .05). Degree of head rotation on the affected side showed significant differences between groups (P < .05), with Group 2 showing significantly better results than group 1 and group 3 (P < .05, both).

Conclusion:
Passive stretching treatment was more effective than other treatments of this study for improvement in degree of head rotation in CMT infants under 3 months of age.

Trial registration:
The trial is registered at the Institutional Review Board of Sahmyook University (IRB number, 2-7001793-AB-N-012019103HR) and the Clinical Research Information Service (CRiS; registry number, KCT0004862)
