Published: November 2021

Objective Body dysmorphic disorder (BDD) represents a bridge between the fields of psychiatry and cosmetic surgery. It is a psychiatric disorder involving altered body image and has been associated with cosmetic surgery. Many studies have investigated BDD following rhinoplasty. However, their findings were inconsistent, which prompted us to conduct this systematic review to obtain strong evidence about the prevalence of BDD among rhinoplasty candidates. Methods We searched the literature using electronic databases such as PubMed, Scopus, Web of Science, and others using keywords relevant to the study outcomes. We also manually examined the references of the included studies and relevant reviews to look for articles that might have been missed during the electronic search. Results Nine articles met the inclusion criteria. We identified 7 other relevant articles; since they had been included in a review conducted in 2016, they were not included in the final list of articles. However, they were included in the discussion, and their findings have been compared with ours. The included articles resulted in a total sample of 712 rhinoplasty candidates. The estimated prevalence rates of BDD in these articles ranged from 22% to 52%, which was considered high by all the authors of the included studies. Conclusion The prevalence of BDD among rhinoplasty candidates is high, and adequate management and interventions are needed to reduce it.
External ear canal exostectomy: influence of surgeon’s experience on 3-years recurrence and occurrence of complications
Authors: Leclère Jean-Christophe , Cerceau Laura , Mornet Emmanuel , Marianowski Rémi 
Published: November 2021

Background External ear canal exostoses are usually bilateral and broad-based, secondary to external ear canal chronic cold exposure, especially water. Objectives The objectives were to analyze the influence of the surgeon’s experience on the 3-year recurrence and on the complication. We also studied the influence of prolonged exposure to cold water on the incidence of recurrence. Material and Methods This monocentric retrospective study included 98 ears operated for canalplasty between 2009 and 2016 by nine different operators including one senior, a junior, and seven beginner surgeons. Senior, Junior, and Beginner groups were compared. Results 3-year recurrence rate was higher in the Beginner and Junior groups than in the Senior group (69% and 38% vs 18%, P = .001). Although there was a difference between the Beginner (69%) and Junior (38%) groups, it was not significant ( P = .407). Among the recurrences, 48% had continued exposure to cold water while only 7% of the ears without recidivism were still exposed ( P < .001, OR = 1.25 [4.4; 36.1]). The complication rates were similar between groups, concerning pain (8% vs 30% vs 12%), per procedure perforation (17% vs 10% vs 16%), scarring disorders (25% vs 20% vs 13%), and osteitis (8% vs 0% vs 1%). Hearing was unaffected. Conclusions This is the first study evaluating the risk of recurrence of external ear canal exostoses after canalplasty based on the surgeon’s experience. This risk of recurrence seems to decrease with the surgeon’s experience. There was no difference in complication rates.
Carnivalesque humor, emotional paradoxes, and street protests in Thailand
Authors: Sombatpoonsiri Janjira 
Published: November 2021

AbstractConventional wisdom has it that street protests are typically driven by rage due to grievances perceived to inflict on a group. This emotive atmosphere can shape protest methods to be vandalistic to the point where armed attacks against targeted opponents are justified. This paper suggests that rage-influenced struggle can be counterproductive as it obstructs a movement from building a coalition board enough to challenge the ruling elites it opposes. This paper argues that carnivalization of protests can prevent this setback in two directions. First, it potentially transforms protesters’ collective emotion from rage to cheerfulness. This effect may lessen a possibility where protesters project violent revenge on those thought to represent the ruling elites. Second, while helping protesters to address sources of their grievances, carnivalesque protests create a “friendly” image that may convince a public audience outside the movement to support its cause. In assessing a political process of carnivalesque protests, this paper bases its analysis on an account of protest actions by Thailand's Red Sunday group emerging after the 2010 crackdown.

Authors: Zendehdel Mojgan , Nouri Faezeh Hossein 
Published: November 2021

Ag-Clinoptilolite/Polyethersulfone (PES/Clin/AgNPs) nanofiber was synthesized through the electrospinning method. The effect of solvent, the amount of Ag-Clinoptilolite, and PES were investigated. Parameters such as electric field, spinning distance, and concentration of the dope solution were studied in order to demonstrate their effects on the electrospinning ability and morphology of the nanofiber. The structure of PES/Clin/AgNPs nanofiber was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) analyses. In the optimum conditions, the nanofibers could be prepared at the size of 250–800 nm. Then, their ability to remove chemical oxygen demand (COD) from real wastewater was studied. The result revealed about 85% removal of COD at pH = 10 and in 10 min for PES/Clin/AgNPs (25%). A successful fabrication method using low-cost natural zeolite and the green polymer was introduced. The reusability of the column was assessed.
The Learning Process in Live-Action Simulation Games: The Impact of Personality, Motivation, Immersion, and Flow on Learning Outcome in a Simulation Game.
Authors: Preuß Anna K. 
Published: November 2021

Background Against the backdrop of the cognitive-motivational process model proposed by Vollmeyer and Rheinberg (1998) , this study investigates how the personality trait need for cognition in combination with a specific situation (short and long version of a live-action simulation game), current motivation, and immersion and flow (mediators) predict the learning outcome in the simulation game EVERYDAY LIFE IN THE CLASSROOM ( Starker & Imhof, 2014 ). Methods N = 138 teacher students played the short 2-hour version of the simulation game, and N = 77 played the long 2-day version. Need for cognition, current motivation, immersion, flow, and learning outcome were measured by self-report questionnaires. Results A hierarchical regression analysis was used to determine the impact of the predictor variables (need for cognition, current motivation, immersion, and flow) on the self-evaluated learning outcome. For the 2-hour group, the predictor variables interest, challenge, and immersion (subscale: engagement) impacted self-reported learning outcome significantly positive. For the 2-day group, significant predictors were need for cognition, interest, and immersion (subscale: engrossment). In comparison of the two game versions, students playing the 2-day version reported significantly higher levels of engagement, engrossment, and learning outcome. Conclusion The cognitive-motivational process model of learning was partly supported: interest and immersion predict learning outcome in the live-action simulation game. The extended 2-day version of the game leads to higher levels of immersion and higher learning outcome, indicating that a longer timeframe secures the desired effects on learning outcome from simulation games. Further research needs to shed light on the interaction of personality traits and immersion.

Authors: Conces Miriam R , Beach Sarah , Pierson Christopher R , Prasad Vinay 
Published: November 2021

Introduction Hypertrophic submucosal nerves, defined as ≥40 µm in diameter, are considered supportive of a diagnosis of HSCR, but the effect of age on nerve diameter has not been well-studied. We sought to determine the distribution of the largest nerve diameter in ganglionic rectal biopsies and the significance of hypertrophic submucosal nerves in the diagnosis of Hirschsprung disease (HSCR) based on age. Methods Rectal biopsies performed in the evaluation of HSCR were retrospectively reviewed from 179 patients (151 ganglionic biopsies, 28 aganglionic biopsies), and the diameter of the largest submucosal nerve was measured. Results In non-Hirschsprung disease (non-HSCR) biopsies, submucosal nerve diameter increased with age. In patients <1 year, the average diameter was 34.1 ± 11.6 µm but increased to 50.8 ± 17.3 µm after 1 year of age. Submucosal nerves ≥40 µm in diameter were significantly associated with HSCR across all ages [HSCR = 25/28 (89.3%) vs non-HSCR = 59/151 (39.1%), p < 0.0001] and remained significant in patients <1 year of age [HSCR = 22/24 (91.7%) vs non-HSCR = 19/91 (20.9%), p < 0.0001]. Conclusions The diameter of submucosal nerves increases with age, and ≥40 µm nerves are common after 1 year of age.

Published: November 2021

Introduction: Non-critically ill neonates at times require venous access to provide peripherally compatible infusions for a limited period (more than 3 days). In such a situation, short peripheral cannulas are not appropriate as their average duration is about 2 days, while—on the other hand—epicutaneous-caval catheters may be too invasive. In these patients, insertion of long peripheral cannulas may be an effective option. Methods: In this observational retrospective study, we revised all “long” peripheral catheters (4 and 6 cm long) inserted by direct Seldinger technique in our neonatal intensive care unit when peripheral venous access was required for more than 3 days. Results: We inserted 52 2Fr polyurethane catheters, either 4 cm long ( n = 25) or 6 cm long ( n = 27) in 52 patients. Mean dwelling time was 4.17 days (range 1–12). Most devices were inserted in the cephalic vein ( n = 18, 35%), and the rest in the saphenous vein ( n = 11, 21%) and other superficial veins. There was no significant correlation between the duration of the device and type of infusion ( p  = 0.40). The main complications were infiltration ( n = 16, 31%) and phlebitis ( n = 8, 15%). The rate of removal due to complications was significantly higher ( p < 0.01) in neonates with bodyweight <2000 g at the time of insertion. Conclusion: In our experience, 2 Fr 4–6 cm long peripheral catheters may be a valid option for neonates requiring peripherally compatible infusions for more than 3 days. The limits of this study are the necessity of training in the technique of insertion and the small size of our sample. The longest dwell was observed in neonates weighing >2000 g at the time of LPC insertion.

Published: November 2021

Background: Pregnancy is considered to influence the disease course in women with multiple sclerosis (MS). Objective: The aim of this study was to investigate the effect of pregnancy on long-term disability accrual in women with MS. Methods: The Danish Multiple Sclerosis Registry (DMSR) was used to identify women diagnosed with clinically isolated syndrome or relapsing-remitting MS. Cox models with pregnancy as a time-dependent exposure and propensity score (PS) models were used to evaluate time to reach confirmed Expanded Disability Status Scale (EDSS) score of 4 and 6. Results: A total of 425 women became parous and 840 remained nulliparous. When including pregnancy as a time-dependent exposure, a non-significant association with time to reach EDSS 4 (hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.61–1.20) and EDSS 6 (HR 0.70, 95% CI 0.40–1.20) was found. Correspondingly, the PS model showed no association with pregnancy on time to reach EDSS 4 (HR 0.85, 95% CI 0.56–1.28). Conclusion: This study concludes that pregnancy does not affect long-term disability accumulation.
The development of a cognitive rehabilitation and psycho-social group programme for teenage and young adult survivors of brain tumours: A feasibility study
Authors: Glazer Daniel , Daniilidi Xeni , Valentino Charlotte 
Published: November 2021

Introduction and aims Treatment for childhood and adolescent brain tumours is often intensive, with significant neurocognitive and psycho-social late effects ( Zeltzer et al., 2009 ). This feasibility Study aimed to inform the development of a cognitive rehabilitation and psycho-social group intervention for Teenage and Young Adult (TYA) survivors of brain tumours. Methods A group-based intervention incorporated ideas from the current evidence base, including psychoeducation and compensatory strategy training, with a focus on real-life goals and improving quality of life. Participants ( N = 19, 13–24 years) were recruited from the University College London Hospital TYA Oncology Service. Participants had received treatment for a malignant brain tumour and had completed their treatment at least 1 year prior to participation. Four group-based, whole-day interventions ran every 3 months throughout a year. Feasibility criteria were established to answer questions about acceptability of the intervention and recruitment. Results Qualitative and quantitative feedback from all four groups demonstrated acceptability and suitability of the intervention with regards to the content, structure and delivery. Recruitment presented more of a challenge with 35% fewer referrals than expected. Discussion and conclusion Feedback suggests that the intervention is suitable and acceptable, whilst limitations include numbers of referrals and referral pathways. Future directions are discussed.

Background Non-disabling stroke (NDS) and transient ischemic attack (TIA) herald the possibility of future, more debilitating vascular events. Evidence is conflicting about potency of exercise and education in reducing risk factors for second stroke. Methods Three-site, single-blinded, randomized controlled trial with 184 participants <3 months of NDS or TIA (mean age, 65 years; 66% male) randomized to usual care (UC) or UC + 12-week program of exercise and education (PREVENT). Primary (resting systolic blood pressure) and secondary outcomes (diastolic blood pressure [DBPrest], high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], total cholesterol [TC], TC/HDL, triglycerides, fasting glucose, and body mass index) were assessed at baseline, post-intervention, and 6- and 12-month follow-up. Peak oxygen consumption (VO2peak) was measured at baseline, post-intervention, 12-month assessments. Results Significant between-group differences at post-intervention favored PREVENT group over UC: DBPrest (mean difference [MD]: −3.2 mmHg, 95% confidence interval [CI]: −6.3, −.2, P = .04) and LDL-C (MD: −.31 mmol/L, 95% CI: −.42, −.20, P = .02). Trends of improvement in PREVENT group were noted in several variables between baseline and 6-month follow-up but not sustained at 12-month follow-up. Of note, VO2 peak did not change over time in either group. Conclusion Impact of PREVENT on vascular risk factor reduction was more modest than anticipated, possibly because several outcome variables approximated normative values at baseline and training intensity may have been sub-optimal. Further investigation is warranted to determine when exercise and education programs are viable adjuncts to pharmaceutical management for reduction of risk factors for second stroke.

Published: November 2021

Background Stroke and transient ischemic attack confer greater risk of cognitive decline and dementia. Aims We used data from the Perindopril Protection Against Recurrent Stroke Study (PROGRESS), a blood pressure-lowering randomized controlled trial in stroke/transient ischemic attack. We evaluated overall and sex-specific differences in treatment effects for cognitive decline/dementia, as well as associations with vascular and stroke-specific predictors,considering death as a competing risk. Methods Multinomial logistic regression was used to estimate overall and sex-specific odds ratios (OR) (95% confidence intervals (CI)) for treatment effects and predictors associated with the risk of cognitive decline/dementia, and the women-to-men ratio of odds ratio (RORs). Results Over a median four years, 763 cognitive decline/dementia (30.9% women) were recorded in 5888 participants. Women had lower odds of cognitive decline/dementia than men (OR 0.78, 95%CI 0.63–0.95). Active treatment was associated with lower odds of cognitive decline/dementia (0.84, 0.72–0.98), with no evidence of sex difference. Higher education (0.96,0.94–0.98 (per year)) and baseline Mini-Mental State Examination (MMSE)) were associated with lower odds of cognitive decline/dementia (0.84,0.82–0.86 (per point higher)). Higher diastolic blood pressure (1.11,1.02–1.20 (per 10 mmHg)), low estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2 (1.27,1.03–1.58), and peripheral arterial disease (1.78,1.26–2.52) were associated with higher odds of cognitive decline/dementia. APOE ɛ4 was not associated with cognitive decline/dementia (1.05 (0.85–1.30)). Low eGFR was more strongly associated with cognitive decline/dementia in women than men (RORs, 1.60 (1.03–2.48)). Diabetes was more strongly associated with men than women. Conclusions Several risk factors were associated with cognitive decline/dementia in people with prior stroke/transient ischemic attack, with notable sex differences. Long-term cognitive sequelae of stroke should be considered to strengthen joint prevention strategies for stroke, cognitive decline, and dementia. Trial Registration: This trial was not registered because enrolment began before 1 July 2005.
Modernism and Record Covers: Raising the Status of Jazz in Sweden
Authors: van Kan Mischa 
Published: November 2021

By introducing a wider understanding of the discourse of modernism at the time that record covers were introduced, this article investigates record covers as a means through which various actors in the Swedish jazz scene connected jazz with modernist art forms. In the 1950s, specific designs for record sleeves became integrated into the ways in which jazz was mediated in Sweden, which coincided with wider debates about whether jazz could be seen as an art form. The main question of this article is: How did the artwork on record covers influence the acceptance of jazz as an art form in Sweden? In responding to this question, the article aims to demonstrate that, in addition to written discourse, visual objects – in this case record covers – were of great importance to the rising status of jazz in Sweden in the 1950s and 1960s. More broadly, I argue that the visual elements in music cultures can be just as important, if not more so, than written forms of discourse, for negotiating the social status of music.
The neurological risks of playing association football
Authors: Cockerell Oliver C , Iino Hayes Natalie , Sylvester Richard 
Published: November 2021

Summary Aims: The present study aims to provide a narrative review of the literature surrounding concussion and head injury in football and its clarity in evaluating the risk of long-term neurological disease. Findings: Epidemiological studies have shown correlations between participation in professional football and increased incidence of neurodegenerative disease and there have been reports of chronic traumatic encephalopathy (CTE) in the brains of former players in autopsy. These findings have been assumed by some to be the result of repetitive brain injury from head injuries and/or from heading the ball over a player's career. Data linking increased heading exposure with dementia is conflicting, and studies are limited by the reliance on retrospection and undocumented reports of concussion. It remains unclear whether CTE is unique to sportsmen or a variant of dementia pathology endemic in the population. Conclusions: Although logically appealing, there is no current evidence that heading is the cause of neurodegeneration amongst footballers and risks should be balanced by the protective mental and physical benefits of the sport. Physicians have an important role in providing balanced views in this emotive and controversial area.
