Published: May 2021

ABSTRACT:

Objective:
Tourette syndrome (TS) and co-occurring mental, behavioral, and developmental disorders (MBDDs) have been shown to affect peer relationships. This study provides nationally representative estimates of diagnosed TS prevalence and the prevalence of parent-reported bullying victimization and perpetration among US children with and without TS.

Methods:
This study included 2016–2017 National Survey of Children's Health data on children aged 6 to 17 years (N = 51,001) with parent-reported responses about TS diagnosis and their child's experiences with bullying victimization and perpetration. We calculated weighted prevalence estimates of diagnosed TS and of bullying indicators among children ever diagnosed with TS compared with peers without TS. We conducted a logistic regression analysis to estimate adjusted prevalence ratios of bullying involvement by TS status, controlling for age, sex, and co-occurring MBDDs.

Results:
By parent report, 0.3% of US children had ever received a diagnosis of TS; most children with a TS diagnosis (83.2%) had a co-occurring MBDD. Among children with TS, 56.1% experienced bullying victimization, 20.7% experienced bullying perpetration, and 15.9% experienced both, compared with 21.6%, 6.0%, and 4.1% for children without TS, respectively. After adjusting for age, sex, and co-occurring MBDDs, only the association between TS and bullying victimization remained statistically significant.

Conclusion:
Compared with children without TS, children with TS overall experience more bullying victimization and perpetration. Health care professionals treating children with TS could assess challenges with peer relationships and co-occurring disorders to provide targeted support and referral.
Serum MicroRNA-137 Serves as a Novel Biomarker for Cerebral Atherosclerosis Diagnosis and Cerebrovascular Event Prediction
Authors: Xuan Jingjing , Shang Meiling , Li Xuelian 
Published: May 2021

Abstract:
MicroRNAs have been reported as biomarkers for various diseases, including cerebral atherosclerosis (AS). In this study, whether serum microRNA-137 (miR-137) could be used as a biomarker for diagnosing cerebral AS and predicting cerebrovascular event was investigated. Quantitative real-time PCR was used to measure the expression of miR-137 in serum. Logistic analysis was used to evaluate the risk factors for the occurrence of cerebral AS, and receiver operating characteristic curves were used to estimate the diagnostic value of miR-137 and other risk factors for AS occurrence. Furthermore, the prognostic value of miR-137 for patients with AS was estimated using Kaplan–Meier survival analysis and Cox regression analysis. The results indicated that serum miR-137 levels were decreased in patients with cerebral AS. The expression of miR-137 was negatively correlated with total cholesterol and low-density lipoprotein cholesterol levels in patients with cerebral AS. The levels of miR-137, total cholesterol, low-density lipoprotein cholesterol, and hypersensitivity C response protein may serve as risk factors for the occurrence of cerebral AS, and miR-137 had diagnostic value for AS screening. Cerebral AS patients with positive cerebrovascular events have low miR-137 expression. Patients with high miR-137 expression had a lower incidence of cerebrovascular adverse events (log-rank P = 0.013), and miR-137 was an independent prognostic marker for the prediction of cerebrovascular event occurrence in patients with cerebral AS. In conclusions, our findings indicate that serum miR-137 levels are decreased in patients with cerebral AS and may be a new biomarker for diagnosing cerebral AS and predicting cerebrovascular events.

Published: May 2021

Abstract:
Long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) was reported to be related to atherosclerosis (AS) progression. However, the underlying mechanism of MALAT1 in AS remains unknown. Quantitative real-time polymerase chain reaction was performed to detect the expression of MALAT1 and miR-330-5p. Western blot was applied to assess the protein levels of cluster of differentiation 36, interleukin-1β, interleukin-6 and tumor necrosis factor-α, phosphorylation of nuclear factor kappa-B inhibitor alpha and phosphorylation of p65. Flow cytometry assay, cell counting kit 8 assay, triglyceride, and total cholesterol detection assays were used to detect the apoptosis, viability, and lipid indexes of THP-1 macrophages-derived foam cells. Online database starbasev2.0 was used to predict the binding sequences between MALAT1 and miR-330-5p and it was verified by dual-luciferase reporter system and RNA immunoprecipitation assay. Besides, an AS mice model was used to evaluate the effect of MALAT1 in vivo. As a result, MALAT1 was overexpressed, whereas miR-330-5p was downregulated in THP-1 macrophages-derived foam cells. MiR-330-5p was a target of MALAT1. MALAT1 depletion inhibited cell formation, apoptosis, and inflammation in THP-1 macrophages-derived foam cells. Besides, MALAT1 overexpression promoted the inflammation in AS mice model, which promoted the pathogenesis of AS. Furthermore, miR-330-5p regulated the nuclear factor kappa light chain enhancer of activated B cells (NF-κB) pathway in THP-1 macrophages-derived foam cells. Moreover, MALAT1 regulated NF-κB signal pathway to mediate the pathogenesis of AS by sponging miR-330-5p. MALAT1 sponges miR-330-5p to activate NF-κB signal pathway in THP-1 macrophages-derived foam cells. This finding may provide a novel biomarker for AS diagnosis.

Published: May 2021

Abstract:
Atrial fibrillation (AF) is a common arrhythmia in the clinic. Ablation failure and recurrence after cardioversion have become medical problems worldwide. An important pathological feature of AF is atrial fibrosis, which increases susceptibility to AF. As an important target of fibrosis signal integration, the signal transducer and activator of transcription 3 (STAT3) signaling pathway plays an important role in fibrosis. Caveolin-1 (CAV1), a cell membrane protein, is involved in a variety of the biological functions of cells. However, the role of CAV1 in atrial fibrosis remains unclear. In this study, Masson's trichrome staining was used to detect the degree of atrial fibrosis, and the expression of CAV1 in the human atrium was evaluated by immunohistochemistry. To further study the role of CAV1, its expression in cultured rat atrial fibroblasts was silenced using siRNAs. Atrial fibroblasts were treated with angiotensin II to observe the effects on CAV1 and the transforming growth factor-β1 and STAT3 signaling pathways. We also detected the effects of CAV1 scaffolding domain (CSD) peptide on fibrosis through the addition of exogenous CSD peptide. The results showed that CAV1 expression decreased with the aggravation of atrial fibrosis and that this effect increased the incidence of AF. The depletion of CAV1 induced excessive extracellular matrix deposition by activating the STAT3 and transforming growth factor-β1/SMAD2 signaling pathways, and this effect was exacerbated by stimulation with angiotensin II and improved by CSD peptide. These data suggested that CAV1 not only plays a critical role in fibrosis progression but also provides a target for the treatment of atrial fibrosis and AF.

Published: May 2021

Abstract:
Pulmonary arterial hypertension (PAH) is a devastating disorder characterized by excessive proliferation and vasoconstriction of small pulmonary artery vascular smooth muscle cells (PASMCs). Coptidis rhizoma (CR) because of the complexity of the components, the underlying pharmacological role and mechanism of it on PAH remains unknown. In this article, the network pharmacological analysis was used to screen the main active constituents of CR and the molecular targets that these constituents act on. Then, we evaluated the importance of berberine and quercetin (biologically active components of CR) on the proliferation and migration of PASMCs and vascular remodeling in experimental models of PAH. Our results showed that berberine and quercetin effectively inhibited the proliferation and migration of hypoxia-induced PASMCs in a manner likely to be mediated by the suppression of MAPK1, NADPH oxidase 4 (NOX4), and cytochrome P450 1B1 (CYP1B1) expression. Furthermore, berberine and quercetin treatment attenuates pulmonary hypertension, reduces right ventricular hypertrophy, and improves pulmonary artery remodeling in monocrotaline-induced pulmonary hypertension in rat models. In conclusion, this research demonstrates CR might be a promising treatment option for PAH, and the network pharmacology approach can be an effective tool to reveal the potential mechanisms of Chinese herbal medicine.

Published: May 2021

Abstract:
Guidelines exist on the management of supratherapeutic/subtherapeutic international normalized ratio (INR) values for patients on warfarin. However, there is a paucity of the literature relating to an acute overdose of warfarin. This is a retrospective cohort study for all acute and acute-on-chronic (AOC) warfarin overdoses reported to the Maryland Poison Center in patients ≥12 years between January 1st, 2000, until October 31st, 2019, managed in a health care facility. The primary outcome was to determine the time after presentation to peak INR. Secondary outcomes included risk factors associated with INR >10 and describing patient characteristics. A total of 163 overdoses were included, 68 acute and 95 AOC. In patients who did not receive reversal therapies, INR peaked at a median value of 3.8 (interquartile range 2.6–5.5) between 24 and 36 hours. The median time to phytonadione was 22.0 hours. Most patients received phytonadione (62.0%), with fewer receiving blood products (16.6%). The median warfarin dose ingested was 75 mg. The AOC group had a greater mean age (56 vs. 43 years), median INR value (2.4 vs. 1.4), and men (62.1% vs. 41.2%). Factors associated with an INR > 10 included initial INR and reported quantity ingested. Peak INR was greater in the AOC than the acute overdose group (6.1 vs. 3.4), although the bleeding rate was similar. Peak INR values after warfarin overdose occur between 24 and 36 hours after presentation. Initial INRs and reported quantity ingested may be useful to predict those needing treatment.

Authors: Januschowski Kai , Boden Karl T. , Macek Andrej M. , Szurman Peter , Bisorca-Gassendorf Lukas , Hoogmartens Caroline , Rickmann Annekatrin 
Published: May 2021

Background/Purpose:
To demonstrate possible complications of a new intraocular lens for sutureless secondary scleral implantation and modifications of the surgical technique to optimize outcomes.

Methods:
A retrospective study of 16 eyes (16 patients) who underwent a secondary intraocular lens implantation using the Carlevale intraocular lens (Soleko, Italy) with two anchor haptics for intrascleral implantation (mean follow-up 2.2 months).

Results:
The visual acuity did not improve statistically significantly postoperatively (P = 0.601). Seven (44%) patients suffered from postoperative hypotonia (intraocular pressure <5 mmHg) during the first three postoperative days.

Conclusion:
Owing to the early postoperative hypotony, we decided to modify the surgical technique. We present several suggestions to optimize the technique and outcome such as positioning the sclerotomies at the 2 and 8 o'clock positions, using 27 G trocars alone and suturing the frown incisions using self-resorbing sutures.

Published: May 2021

Background/Purpose:
To characterize the nature of posterior segment ocular injuries in combat trauma.

Methods:
Eyes in the Walter Reed Ocular Trauma Database were evaluated for the presence of posterior segment injury. Final visual outcomes in open-globe versus closed-globe injuries and by zone of injury and the types of posterior segment injuries in open-globe versus closed-globe injuries were assessed.

Results:
Four hundred fifty-two of 890 eyes (50.8%) had at least one posterior segment injury. The mechanism of injury was most commonly an improvised explosive device in 280 (62.0%) eyes. Sixty-one patients (13.5%) had a Zone I injury, 50 (11.1%) a Zone II injury, and 341 (75.4%) a Zone III injury. Patients with Zone I injuries were more likely to have a final visual acuity of 20/200 or better compared with patients with either a Zone II (P < 0.001) or Zone III injury (P = 0.007). Eyes with a closed-globe injury were more likely to have a final visual acuity of 20/200 or better compared with those with an open-globe injury (P < 0.001). Furthermore, closed-globe injury compared with open-globe injury had a lower risk of vitreous hemorrhage (odds ratio 0.32, P < 0.001), proliferative vitreoretinopathy (odds ratio 0.14, P < 0.001), and retinal detachment (odds ratio 0.18, P < 0.001) but a higher risk of chorioretinal rupture (odds ratio 2.82, P < 0.001) and macular hole (odds ratio 3.46, P = 0.004).

Conclusion:
Patients with combat ophthalmic trauma had similar posterior segment injury patterns to civilian trauma in open-globe versus closed-globe injuries. Zone II and III injuries were associated with a worse visual prognosis.
MICROVASCULAR LEAKAGE IS A POOR PROGNOSTIC FACTOR FOR IDIOPATHIC EPIRETINAL MEMBRANE
Authors: Kwon Han Jo , Park Sung Who , Lee Ji Eun , Byon Iksoo 
Published: May 2021

Purpose:
To investigate the angiographic findings assessed using fluorescein angiography and their prognostic values of idiopathic epiretinal membrane.

Methods:
Seventy-three eyes of idiopathic epiretinal membrane that had been followed up for 6 months after surgical treatment were included. Midphase fluorescein angiography images were obtained at baseline. Structural changes, including central subfield macular thickness, intraretinal cystic lesion, and ectopic inner retinal layer on the fovea, were assessed using optical coherence tomography. The main outcome measures were microvascular leakage (ML) and its association with optical coherence tomography findings and best-corrected visual acuity (BCVA).

Results:
Of a total of 73 eyes, 37 showed ML and had worse BCVA (P = 0.040), greater central subfield macular thickness (P = 0.028), and more ectopic inner retinal layer (P < 0.001) than those without ML at baseline. Also, ML was associated with worse postoperative BCVA (P < 0.001) and ectopic inner retinal layers (P < 0.001; P = 0.034) at baseline and 6 months. The baseline factors associated with postoperative BCVA of ≥20/25 were better BCVA (P = 0.027) and the absence of ML (P < 0.001).

Conclusion:
Half of the idiopathic epiretinal membrane eyes showed that ML was associated with inner retinal deformity and poor visual recovery. Fluorescein angiography helped to predict visual prognosis after idiopathic epiretinal membrane surgery.

Authors: Gui Wei , Au Adrian , Rabina Gilad , Kapelushnik Noa , Cohen Shai , Masarwa Dua , Hosseini Hamid , Heilweil Gad , Schwartz Shulamit , Loewenstein Anat , Schwartz Steven D. 
Published: May 2021

Purpose:
To define injection index (II) and assess its impact on visual acuity (VA) in pigment epithelial detachment from age-related macular degeneration over 5 years.

Methods:
Injection index is defined as the mean anti–vascular endothelial growth factor injections per year from presentation. A retrospective study of 256 eyes in 213 patients was performed. Patients were stratified by II (high: ≥9, low: <9).

Results:
Baseline characteristics showed no differences across II groups. Mean (range) follow-up, in years, was 5.02 (1.04–12.74) for all patients. Mean logMAR VA (Snellen VA) were 0.60 (20/80) and 0.56 (20/73) at baseline, 0.52 (20/66) and 0.59 (20/78) at Year 1, 0.45 (20/56) and 0.67 (20/94) at Year 2, 0.38 (20/48) and 0.66 (20/91) at Year 3, 0.41 (20/51) and 0.89 (20/155) at Year 4, and 0.35 (20/45) and 0.79 (20/123) at Year 5 for the high and low II groups, respectively. Linear regression analysis showed a gain of 0.5 approxETDRS letters with each additional injection per year.

Conclusion:
Increased II was associated with better mean VA, suggesting that long-term continuous vascular endothelial growth factor suppression may improve VA in eyes thought to carry poor prognoses.
Determining the Most Suitable Tomography-Based Parameters to Describe Progression in Keratoconus. The Retrospective Digital Computer Analysis of Keratoconus Evolution Project
Authors: Jiménez-García Marta , Kreps Elke O. , Ní Dhubhghaill Sorcha , Koppen Carina , Rozema Jos J. ,   The REDCAKE Study Group
Published: May 2021

Objectives:
To identify the most suitable parameters to describe keratoconus progression.

Methods:
Longitudinal retrospective cohort study. Monotonicity and consistency of over 250 parameters extracted from the Pentacam tomographies (Oculus, Germany) of 743 patients was analyzed. Repeatability was calculated for 69 patients (published elsewhere). The parameters were scored based on their performance for each desired feature and a global ranking was created.

Results:
Overall, parameters that average a higher number of corneal points performed better than single-point parameters. Zonal keratometries on areas surrounding the maximum curvature point and the steepest front keratometry performed best, followed by front best-fit sphere and mean keratometry of both surfaces. Platform-dependent indices (e.g., Belin-Ambrósio Deviation- or index height decentration-) obtained good scores, but platform-independent LOGIK performed slightly better. Finally, although minimum radius in both surfaces worked competently, minimum pachymetry (PachyMin) performed considerably poorer.

Conclusions:
We presented a list of parameters whose behavior was repeatable, monotonic and consistent, features desirable to describe change. The parameters normally used to follow keratoconus progression may not be the most adequate, as evidenced by the poor performance of PachyMin. Although calculated for a specific Scheimpflug device, most of the best-performing parameters are platform-independent variables, and results may be generalized, pending validation.
The symmetry indices of malar mounds for zygomatic bone fracture management based on a computed tomographic model
Authors: Wang Tien-Hsiang , Yu Wen-Chan , Chen Zih-Hua , Tien Yao-Hsuan , Chen Wei-Ming , Chiu Fang-Yau , Wang Shyh-Jen 
Published: May 2021

Background:
To date, plastic surgeons do not have an objective method of measuring facial symmetry for zygomatic bone fracture management. Based on clinical practice, the authors utilized a 3-dimensional (3D) model to propose the symmetry index from the anterior view (SIAV) and the symmetry index from inferior view (SIIV). This study aimed to assess the application of these 2 indices.

Methods:
The SIAV is defined as the distance between the superior and lower orbital rims (DSLOR) of the defective side divided by that of the healthy side in the anterior view. The SIIV is defined as the area within the region of interest (AROI) of the defective side divided by that of the healthy side in the inferior view. We retrospectively reviewed 95 patients who underwent zygomatic fracture surgery at our medical center from January 2017 to September 2020. The Patients who had bilateral zygomatic fractures and did not have both pre- and postoperative computed tomography (CT) images were excluded.

Results:
Five out of the 95 patients were enrolled in this study. The difference between pre- and postoperative mean AROI and DSLOR on the healthy side was not significant. The insignificant difference indicates the repeatability of the measurement of the 3D skull model and different CT machines would not affect the calculation of AROI and DSLOR. The mean values of postoperative SIAV (1.06 ± 0.07) and SIIV (1.02 ± 0.08) were closer to 1 than the preoperative values (0.97 ± 0.09 and 1.10 ± 0.12). Although the difference was not statistically significant, the SIIV and SIAV would numerically present the changes in malar bone fracture postoperatively.

Conclusion:
The SIAV and SIIV based on clinical practice could numerically assess the symmetry of the malar mound.

Published: May 2021

Objective:
This study aimed to investigate the mediating effects of eudemonic well-being (EWB) at work for the associations between psychosocial work environment and overall EWB among Japanese workers.

Methods:
We conducted a cross-sectional study using data from a 2018 survey. psychosocial work environment measures included: job demands, job control, and supervisor and coworker support. Path analysis using structural equation modeling and mediation analysis were applied to examine the mediating effects of work EWB.

Results:
A total of 834 workers were analyzed. Work EWB completely mediated the associations of job control (β = 0.288, P < 0.001) and coworker support with overall EWB (β = 0.178, P < 0.001).

Conclusions:
The effects of job control and coworker support associated with overall EWB were fully mediated by work EWB.
