Published: June 2021

Abstract
Acne is associated with depression and anxiety; however, the relationship between acne and suicide is still unclear. This study is aimed to evaluate the association between acne and suicide by conducting a meta-analysis. Studies were identified by electronic searches of the PubMed and EMBASE databases from their inception through Jan 10, 2020. Two authors separately assessed the quality and extracted data from the selected studies. When the heterogeneity was significant, we used a random-effects model to calculate overall pooled risk estimates.
Five studies involving a total of 2,276,798 participants were finally included in the meta-analysis; 52,075 participants had acne. Suicide was positively associated with acne in the overall analysis (odds ratio (OR) 1.50, 95% confidence interval (95% CI): 1.09–2.06, P = .004, I2 = 74.1%). Subgroup analyses were performed for suicidal behavior groups (P = .002, I2 = 80.4%), suicidal ideation or thoughts groups (P = .849, I2 = 0.0%), International Classification of Diseases version 9 (ICD-9) groups (P = .137, I2 = 49.6%), non-ICD-9 groups (P = .950, I2 = 0.0%), American groups (P = .311, I2 = 2.4%), and non-American groups (P = .943, I2 = 0.0%). Sensitivity analyses indicated flawed results. No publication bias was detected.
Acne may significantly increase suicide risk. Clinicians should actively treat acne and consider suicide screening. Further international studies with high-quality analyses are needed as more data are published.
Ethical approval and patient consent are not required because this study is a literature-based study.
The prevalence and break down of narrow anterior chamber angle pathology presenting to a general ophthalmology clinic
Authors: Jain Nikhil , Zia Rashad 
Published: June 2021

Abstract
To approximate the breakdown of narrow anterior chamber angle conditions, on general ophthalmology clinics, in the predominantly white population of the South East Kent region in the United Kingdom.
A review was done of all patients attending a secondary care ophthalmology general clinic over a 3-year period. Patients were assessed with: slitlamp biomicroscopy with indentation gonioscopy; SD optical coherence tomography, Humphrey visual field analyzer, and high frequency ultrasound and categorized into various narrow angle conditions. These were: narrow Van Herrick but open angle; primary narrow angle but nonoccludable; primary angle closure suspect; primary angle closure; chronic narrow angle glaucoma; plateau iris configuration; plateau iris syndrome, and phacomorphic narrow angle.
A total of 14,520 patients were referred to the clinic, of those 10,491 attended and were analyzed. Six hundred seventy four (6.4%) of the patients had some form of narrow angle condition in at least 1 eye. The majority of these patients were at relative low risk of pathology such as nonoccludable narrow angles (359/53.3%) and narrow Van Herrick but open angles (93/13.8%). 8.8% of all the narrow angle patients had primary angle closure suspect or primary angle closure. Plateau iris pathology was seen in 68 (10.1%) of patients with 18 (26%) having confirmed plateau iris syndrome after peripheral iridotomy. Phacomorphic pathology was confirmed in 75 (11.1%) patients.
Narrow angle patients form a significant proportion (6.4%) of those attending general ophthalmology clinic in the predominantly white population in the South East Kent Region of the United Kingdom. The majority of these (67.1%) are at a relatively low risk of developing acute or chronic angle closure glaucoma. Of the remaining patients 8.8% have primary angle closure suspect or primary angle closure and 2.9% have already progressed to chronic narrow angle closure glaucoma. Plateau iris pathology and phacomorphic glaucoma account for the remainder of the presentations.

Published: June 2021

Abstract

Background:
Thymic epithelial tumors (TETs), originating from the thymic epithelial cells, are the most common primary neoplasms of the anterior mediastinum. Emerging evidence demonstrated that the competing endogenous RNAs (ceRNAs) exerted a crucial effect on tumor development. Hence, it is urgent to understand the regulatory mechanism of ceRNAs in TETs and its impact on tumor prognosis.

Methods:
TETs datasets were harvested from the UCSC Xena as the training cohort, followed by differentially expressed mRNAs (DEmRNAs), lncRNAs (DElncRNAs), and miRNAs (DEmiRNAs) at different pathologic type (A, AB, B, and TC) identified via DESeq2 package. clusterProfiler package was utilized to carry out gene ontology and Kyoto encyclopedia of genes and genomes functional analysis on the DEmRNAs. Subsequently, the lncRNA-miRNA-mRNA regulatory network was constructed to screen the key DEmRNAs. After the key DEmRNAs were verified in the external cohort from Gene Expression Omnibus database, their associated-ceRNAs modules were used to perform the K-M and Cox regression analysis to build a prognostic significance for TETs. Lastly, the feasibility of the prognostic significance was validated by receiver operating characteristic (ROC) curves and the area under the curve.

Results:
Finally, a total of 463 DEmRNAs, 87 DElncRNAs, and 20 DEmiRNAs were obtained from the intersection of differentially expressed genes in different pathological types of TETs. Functional enrichment analysis showed that the DEmRNAs were closely related to cell proliferation and tumor development. After lncRNA-miRNA-mRNA network construction and external cohort validation, a total of 4 DEmRNAs DOCK11, MCAM, MYO10, and WASF3 were identified and their associated-ceRNA modules were significantly associated with prognosis, which contained 3 lncRNAs (lncRNA LINC00665, lncRNA NR2F1-AS1, and lncRNA RP11-285A1.1), 4 mRNAs (DOCK11, MCAM, MYO10, and WASF3), and 4 miRNAs (hsa-mir-143, hsa-mir-141, hsa-mir-140, and hsa-mir-3199). Meanwhile, ROC curves verified the accuracy of prediction ability of the screened ceRNA modules for prognosis of TETs.

Conclusion:
Our study revealed that ceRNAs modules might exert a crucial role in the progression of TETs. The mRNA associated-ceRNA modules could effectively predict the prognosis of TETs, which might be the potential prognostic and therapeutic markers for TETs patients.

Published: June 2021

Abstract
The aim of the case study is to examine the association between hypertension and the level of bone metabolism markers in newly diagnosed osteoporotic patients.
A cross-sectional study of 518 subjects was done to see the association between hypertension and the level of osteocalcin (OC), bone-specific alkaline phosphatase (B-ALP), Tartrate-resistant acid phosphatase (TRAP.5B), and 25-hydroxy vitamin D (25-OHD). There were 243 (46.9%) osteoporosis patients with hypertension. Both univariate and multivariate analysis have suggested that lower OC and 25-OHD levels were associated with hypertension. The potential confounders-adjusted OC level was significantly lower in hypertensive female group than that in the female without hypertension group [β = -0.20, 95% confidence interval (95% CI) = -0.37 to -0.03, P = .02 in final adjust model]. The potential confounders-adjusted 25-OHD level was significantly lower in hypertensive male group than that in male without hypertension group (β = -0.34, 95% CI = -0.58 to -0.10, P = .01 in final adjust model). The B-ALP and TRACP.5B levels were positively associated with hypertension in all patients or subgroup analysis. However, all the correlations had no statistical significance for the B-ALP and TRACP.5B.
In conclusion, the hypertension was associated with low level of OC and 25-OHD. Hypertension probably led to low bone turnover, which may be one of the mechanisms of hypertension-related osteoporosis.
Ropivacaine continuous wound infusion after mastectomy with immediate autologous breast reconstruction
Authors: Lee Jeong Eun , Park Young Je , Lee Jeong Woo 
Published: June 2021

Abstract
Continuous wound infusion usually provides postoperative analgesia as a multimodal analgesia with systemic opioid use. When continuous wound infusion of local anesthetics (LA) supports successful postoperative analgesia without systemic opioid use, the side effects of opioid can be reduced. Nevertheless, continuous wound infusion after mastectomy with immediate autologous breast reconstruction leads to concerns about wound healing. This study evaluated analgesic effects and wound healing conditions of continuous wound infusion of LA compared with opioid-based, intravenous patient-controlled analgesia (IV PCA) in mastectomy with immediate autologous breast reconstruction.
This retrospective observational study included females, aged between 33 and 67 years, who underwent mastectomy with immediate autologous breast reconstruction. Sixty-five patients were enrolled. The eligible patients were placed into 2 groups for managing postoperative pain, one used continuous wound infusion with 0.5% ropivacaine (ON-Q, n = 32) and the other used a fentanyl-based IV PCA (IV PCA, n = 33). Using the electronic medical record system, the postoperative recovery profiles were examined over 5 days using a visual analogue scale (VAS), incidence of postoperative nausea and vomiting (PONV), incidence of sleep disturbance, frequency of rescue analgesic use, analgesia-related adverse events, length of hospital stay, and degree of patient satisfaction. The condition of the surgical wound was observed for 1 year after surgery.
The primary endpoint was the intensity of pain at 6 hours after surgery. The VAS was comparable between the groups (P > .05). Although recovery profiles and the degree of patient satisfaction were similar between the groups, the incidence of PONV was significantly lower in the ON-Q group than in the IV PCA group on the day of surgery and postoperative day 1. No patients had severe wound complications. The satisfaction score of analgesia in the ON-Q group was comparable with that of the patients in the IV PCA group.
This study demonstrates that single use of continuous wound infusion showed comparable analgesia with fentanyl-based IV PCA in patients who underwent mastectomy with immediate autologous breast reconstruction. Furthermore, the continuous infusion of LA directly on the surgical site did not significantly affect wound healing.
Increased photokeratitis during the coronavirus disease 2019 pandemic
Authors: Wang YingMing , Lou Jing , Ji Ye , Wang ZhenYu 
Published: June 2021

Abstract
An increased incidence of photokeratitis has occurred during the coronavirus disease 2019 (COVID-19) pandemic due to improper and unprotected use of ultraviolet lamps. Here, we summarize the clinical and epidemiological features of this increased incidence of photokeratitis and share advice in using health education to prevent it.
We collected data from patients diagnosed with photokeratitis from October 7, 2019 to December 1, 2019, and from February 17, 2020 to April 12, 2020, and compared the frequency of onset, site of ultraviolet radiation (UVR) exposure, reason for exposure, exposure time, and recovery time. We also implemented and evaluated multiple measures of public health education to prevent increased disease.
After the COVID-19 outbreak, the frequency of onset of photokeratitis increased significantly, especially among young women. The main reason for UVR exposure changed from welding to disinfection. The incidence sites varied, and the exposure time was longer. As a result, patients needed a longer time to recover. Positive health education was an useful and convenient measure to prevent the disease.
While the COVID-19 pandemic is ongoing, more attention should be paid to public health and implement positive measures to prevent photokeratitis.

Abstract
Most patients with coronavirus disease 2019 (COVID-19) have mild to moderate illness not requiring hospitalization. However, no study has detailed the evolution of symptoms in the first month of illness.
At our institution, we conducted remote (telephone and video) visits for all adult outpatients diagnosed with COVID-19 within 24 h of a positive nasopharyngeal polymerase chain test for SARS-CoV-2. We repeated regular video visits at 7, 14, and 28 days after the positive test, retrospectively reviewed the prospective data collected in the remote visits, and constructed a week by week profile of clinical illness, through week 4 of illness.
We reviewed the courses of 458 symptomatic patients diagnosed between March 12, 2020, and June 22, 2020, and characterized their weekly courses. Common initial symptoms included fever, headache, cough, and chest pain, which frequently persisted through week 3 or longer. Upper respiratory or gastrointestinal symptoms were much shorter lived, present primarily in week 1. Anosmia/ageusia peaked in weeks 2 to 3. Emergency department visits were frequent, with 128 visits in the 423 patients who were not hospitalized and 48 visits among the 35 outpatients (7.6%) who were eventually hospitalized (2 subsequently died). By the fourth week, 28.9% said their illness had completely resolved. After the 4-week follow up, 20 (4.7%) of the 423 nonhospitalized patients had further medical evaluation and management for subacute or chronic COVID-19 symptoms.
Mild to moderate outpatient COVID-19 is a prolonged illness, with evolving symptoms commonly lasting into the fourth week of illness.
Which radiograph is most accurate for assessing hip joint penetration in infra-acetabular screw placement?
Authors: Lim Eic Ju , Sakong Seungyeob , Choi Wonseok , Oh Jong-Keon , Cho Jae-Woo 
Published: June 2021

Abstract
Although infra-acetabular screws have been used for anterior and posterior column transfixation, a screw penetrating the hip joint can result in harmful complications. However, the most accurate intraoperative radiologic imaging tool for identifying articular penetration has not been established. The purpose of the present study was, therefore, to evaluate the consistency with which standard pelvic radiographs compared with computed tomography (CT) can be used for demonstrating articular penetration.
This retrospective review was performed between January 2015 and December 2020. We evaluated the records of patients with acetabular or pelvic fractures who underwent open reduction and internal fixation with infra-acetabular screw placement. We collected demographic data and described infra-acetabular screw placement as follows: ideal placement, articular penetration, and out of the bone. Articular penetration was assessed independently on each pelvic radiograph and compared statistically with the CT scans. Sensitivity, specificity, correct interpretation rate, and prevalence-adjusted bias-adjusted kappa (PABAK) were calculated for each radiograph.
Thirty-nine patients underwent infra-acetabular screw placement. The mean age of patients was 55 years (range, 27–90 years); there were 29 men and 10 women. One patient underwent bilateral infra-acetabular screw placement; therefore, 40 infra-acetabular screws were included in total. Six (6/40, 15%) infra-acetabular screws showed articular penetration on CT and two (2/40, 5%) showed infra-acetabular screws extending out of the bone. Hip joint penetration was correctly identified at a rate of 92.5% (95% confidence interval [CI], 79.6–98.4%) on the outlet view and 87.5% (95% CI, 73.2–95.8%) on the anteroposterior (AP) view. The PABAK for the agreement between pelvic radiographs and CT scans was 0.85 in the outlet view and 0.75 in the AP view.
The outlet view is an accurate method for detecting articular penetration of infra-acetabular screws. We recommend the insertion of an infra-acetabular screw under fluoroscopic outlet view to avoid articular penetration intraoperatively.
Panintestinal capsule endoscopy in patients with celiac disease
Authors: Foerster Friedrich , Neumann Helmut 
Published: June 2021

Introduction
Capsule endoscopy has proven its utility in diagnosing villous atrophy and lymphoma in patients with celiac disease. Recently, a novel capsule endoscopy system was introduced which enables the examination of the small and large bowel. So far, it has not been evaluated in patients with celiac disease.

Objective
The primary objective of this study was to evaluate the novel panintestinal capsule endoscopy system in patients with celiac disease.

Methods
Eleven patients with histologically proven celiac disease (Marsh 0–IV), who underwent a panintestinal capsule endoscopy between March 2018 and April 2019 at our institution, were included in this retrospective single-center study. All patients performed standard bowel preparation prior to the examination. Diagnostic yield, safety and therapeutic impact were analyzed. In addition, the correlation between capsule endoscopy findings and the histology of the duodenal mucosa was assessed.

Results
Panintestinal capsule endoscopy was feasible and produced an acceptable visualization quality in all cases. Concordance of capsule endoscopy findings with the Marsh classification showed a good correlation (r = 0.8). No lymphomas were detected. Evaluation of the colon revealed diminutive polyps (median size 4 mm) in 18% of patients.

Conclusions
The novel panintestinal capsule endoscopy system shows a fair correlation with the Marsh classification in patients with celiac disease. It is also capable of identifying colon polyps. Therefore, the novel panintestinal capsule endoscopy system can be considered for patients with celiac disease and an indication for capsule endoscopy.

Published: June 2021

ABSTRACT

Objectives:
The aim of the study was to evaluate the neurocognitive and motor development of biliary atresia (BA) patients in childhood and adolescence and to identify risk factors for impaired outcome.

Methods:
We invited all BA patients between ages 1 and 20 years followed up at Helsinki University Children's Hospital in Finland between 1 January 2019 to 31 January 2020 to participate. All participants underwent age-appropriate validated neurocognitive tests. Participants between 3.0 and 16.9 years of age were assessed with the Movement Assessment Battery for children, version 2. Guardians of participants between ages 5 and 17 years filled the Five-to-Fifteen-Revised (5-15R) parental questionnaire.

Results:
The mean (±standard deviation [SD]) total intelligence quotient (IQ) of the 39 participants was 91 ± 15, lower compared with test norms (mean IQ 100 ± 15, P < 0.01). Earlier clearance of jaundice (COJ) had a positive effect on mean (±SD) total IQ (COJ <3 months 96 ± 13 vs COJ ≥3 months post-portoenterostomy 84 ± 13, P < 0.05). Out of 30 participants assessed, 13 (43%) were either at risk or fulfilled the criteria for impaired motor development. Guardians reported elevated rates of functional difficulties affecting everyday life. There were no significant differences between native liver and liver transplanted (16/41%) groups.

Conclusions:
IQ is moderately, and motor scores markedly impaired in BA patients compared with normative data. Standardised cognitive and motor assessment before school-age for all BA patients is advisable to identify individuals in need of additional support.

Objective:
We used data from a routine HIV testing program to develop risk scores to identify patients with undiagnosed HIV infection while reducing the number of total tests performed.

Design:
Multivariate logistic regression.

Methods:
We included demographic factors from HIV testing data collected in 134 Botswana Ministry of Health & Wellness facilities during two periods (1 October 2018– 19 August 2019 and 1 December 2019 to 30 March 2020). In period 2, the program collected additional demographic and risk factors. We randomly split each period into prediction/validation datasets and used multivariate logistic regression to identify factors associated with positivity; factors with adjusted odds ratios at least 1.5 were included in the risk score with weights equal to their coefficient. We applied a range of risk score cutoffs to validation datasets to determine tests averted, test positivity, positives missed, and costs averted.

Results:
In period 1, three factors were significantly associated with HIV positivity (coefficients range 0.44–0.87). In period 2, 12 such factors were identified (coefficients range 0.44–1.37). In period 1, application of risk score cutoff at least 1.0 would result in 50% fewer tests performed and capture 61% of positives. In period 2, a cutoff at least 1.0 would result in 13% fewer tests and capture 96% of positives; a cutoff at least 2.0 would result in 40% fewer tests and capture 83% of positives. Costs averted ranged from 12.1 to 52.3%.

Conclusion:
Botswana's testing program could decrease testing volume but may delay diagnosis of some positive patients. Whether this trade-off is worthwhile depends on operational considerations, impact of testing volume on program costs, and implications of delayed diagnoses.
