Authors: Lee Sang Ki , Ma Sang Beom , Kim Woosuk , Choy Won Sik 
Published: February 2021

PurposeAlthough the pronator quadratus (PQ) preservation approach for volar plating of distal radius fracture has been commonly used recently, its superiority to the conventional PQ dissection approach, especially for comminuted intra-articular distal radius fractures, has not been well established. The purpose of this study was to assess the efficacy of PQ preservation for comminuted intra-articular fractures and to evaluate the healed PQ during hardware removal surgery.Materials and MethodsFrom January 2014 to March 2019, 86 patients who underwent both volar plating for AO Foundation/Orthopedic Trauma Association classification type C2 or C3 distal radius fractures and subsequent hardware removal were assessed in this study. Radiographic measurements, clinical outcomes at each follow-up, and the integrity of healed PQ during hardware removal were compared between the PQ dissection (group D) and PQ preservation (group P) groups.ResultsComplete union with acceptable reduction on radiographic measurements was achieved in both groups. Group P showed a statistically significant earlier recovery of clinical outcomes at 2 weeks and 1 month postoperatively and improved anatomical restoration of PQ muscle covering the plate, which was identified during hardware removal surgery. Flexor tendon rupture was identified in 2 patients (5%) and tenosynovitis in 6 patients (14%) in group D; no patient had flexor tendon rupture (0%), and 2 patients (5%) had tenosynovitis in group P.ConclusionsPronator quadratus preservation approach for volar plating is easily applicable and useful even for comminuted intra-articular distal radius fractures and is helpful for earlier restoration of wrist function and in preventing flexor tendon problems in the latter postoperative period.
The Linton A. Whitaker Legacy
Authors: Azoury Saïd C. , Kalmar Christopher L. , Zimmerman Carrie E. , Swanson Jordan W. , Serletti Joseph M. , Bartlett Scott P. , Taylor Jesse A. 
Published: February 2021

Background
Linton A. Whitaker is a pioneer of craniofacial surgery. He served as chief of plastic surgery at the Children's Hospital of Philadelphia and University of Pennsylvania and director of the craniofacial training program. Herein, the authors reflect on his legacy by studying the accomplishments of his trainees.

Methods
Dr Whitaker's trainees who completed (a) craniofacial fellowship training while he was director of the program or (b) residency training while he was chief were identified. Curricula vitae were reviewed. Variables analyzed included geographic locations, practice types, academic leadership positions, scholarly work, and bibliometric data.

Results
Between 1980 and 2011, 34 surgeons completed craniofacial fellowship training under Dr Whitaker, and 11 completed plastic surgery training under his chairmanship and subsequent craniofacial fellowship. The majority had active craniofacial practices after training (83.3%) and practice in an academic setting (78.0%). Most settled in the northeast (31.1%) and south (31.1%) but across 24 states nationally. Overall, the mean ± SD number of publications was 76 ± 81 (range, 2–339); book chapters, 23 ± 29 (0–135); H-index, 18 ± 12 (1–45); and grants, 13 ± 16 (0–66). Of those who pursued academia, 53.1% were promoted to full professor, 46.9% had a program director role, 75.0% directed a craniofacial program, and 53.1% achieved the rank of chief/chair.

Conclusions
Equally important to Dr Whitaker's clinical contributions in plastic and craniofacial surgery is the development and success of his trainees who will undoubtedly continue the legacy of training the next generation of craniofacial surgeon leaders.

Purpose
The timing and management of patients with cleft palates have been controversial. Early soft palate closure at the time of cleft lip repair followed by hard palate closure at a second stage has been hypothesized to improve speech and audiology outcomes. This study compares cleft palate patients who have undergone single-stage versus 2-stage cleft palate repairs and the outcomes on speech and hearing.

Methods
A retrospective chart review identified patients with diagnosis of cleft lip with complete cleft palate who underwent either single or 2-stage repair from 2006 to 2012. Data collected included age at each surgery, necessity of further speech surgery for velopharyngeal insufficiency, frequency of tympanostomy tube placement, presence of hearing loss, and speech assessment data graded per the validated Americleft speech scale.

Results
A total of 84 patients were identified and subdivided into groups of single-stage and 2-stage repair. The mean age at the time of single-stage palate repair was 13.3 months. For the 2-stage group, the mean ages were 4.2 and 11.8 months for the soft palate and hard palate repairs, respectively. Comparing the single-stage versus 2-stage palate repairs, there was no significant difference in all speech parameters including hypernasality, hyponasality, nasal air emission, articulation, expressive language, receptive language, speech intelligibility, and speech acceptability for both unilateral and bilateral cleft lip/palate patients. Two-stage repair was associated with increased number of tympanostomy tube placement compared with single-stage repair (relative risk, 1.74; P = 0.009), and the first set of tubes was performed at a statistically significantly younger age, 4.5 months in the 2-stage repair compared with 16.9 months in the single-stage (P = 0.012) with 87.5% performed with first stage of repair. However, there was no difference in the types, degrees of hearing loss, or the presence of at least mild conductive hearing loss at latest follow-up audiograms between the groups.

Conclusions
There was no significant benefit with respect to speech or hearing outcomes between single-stage and 2-stage cleft palate repairs. This advocates for surgeon and family preference in the timing of cleft palate repair.
Subcortical Structure Disruption in Diffusion Tensor Tractography of the Patient With the Syndrome of Irreversible Lithium-Effectuated Neurotoxicity Combined With Neuroleptic Malignant Syndrome: A Case Report
Authors: Rhee Seung Yeon , Kim Hyoung Seop 
Published: February 2021

Background
Lithium can cause not only acute neurotoxicity but also chronic and persistent neurotoxicity known as syndrome of irreversible lithium-effectuated neurotoxicity (SILENT). The combined use of lithium and antipsychotics increases the possibility of SILENT. Neuroleptic malignant syndrome (NMS) is a reversible, idiosyncratic, and potentially life-threatening reaction, which is usually caused by antipsychotics and other agents, such as mood stabilizers (eg, lithium and metoclopramide). Neuroleptic malignant syndrome is characterized by hyperpyrexia, muscle rigidity, and altered mental status. We describe a case of SILENT combined with NMS in this case report.

Case Report
A 46-year-old man who had been treated with lithium for bipolar II disorder since 2008 was prescribed lorazepam, lithium, and aripiprazole at his last outpatient visit. The patient experienced financial difficulties (bankruptcy) and suffered severe emotional stress. Subsequently, he overused lorazepam, lithium, and aripiprazole. Two days after the overdose, he experienced a high fever, confused mental status, and rhabdomyolysis and was diagnosed with NMS. However, even after resolution of NMS-related symptoms, quadriplegia, visual field defects, ataxia, and severe dysarthria persisted. A positron emission tomography-computed tomography brain scan showed decreased 15F-fludeoxyglucose uptake in bilateral primary motor cortices and in the thalamus, midbrain, and cerebellum. Brain magnetic resonance imaging diffusion tensor imaging and diffusion tensor tractography of the subcortical tracts revealed structural disruptions, especially in the corticospinal tract, dentatorubrothalamic tract, and optic radiation, which seemed to be correlated with the clinical symptoms of the patient.

Conclusion
This case suggests that the clinical use of diffusion tensor tractography could be helpful to explain the clinical features in the case of SILENT combined with NMS.

Published: February 2021

Background
Cognitive difficulties have a significant impact on life functioning and overall well-being in patients with psychosis spectrum disorders (PSDs). There are indications that continuous use of benzodiazepines (BZDs) in various patient groups has a detrimental effect on cognition. Our aim was to explore the association between long-term BZD prescription, global functioning, and cognitive functioning in persons with PSD.

Methods
This exploratory study included 55 PSD patients, recruited from 2 outpatient services in Serbia. Patients were grouped into BZD long-term prescription group and BZD-other group. Brief Psychiatric Rating Scale was used for symptom assessment, functioning was measured by Global Assessment and Functioning Scale, and cognition was assessed by the Global Assessment of Functioning–Cognition in Schizophrenia Scale.

Results
The sample comprised 52.7% patients who were prescribed with BZD for 6 months or more continually (29/55), with a mean daily dose of 3.16 ± 0.66 mg lorazepam equivalents. There were no differences between study groups in any of the sociodemographic characteristics, duration of illness, or antipsychotic daily dosages. The BZD long-term prescription group had lower global (P < 0.01) and cognitive functioning (P < 0.01), higher Brief Psychiatric Rating Scale scores (1.86 vs 1.58, respectively, P < 0.01), and more psychotropic drugs prescribed on a daily basis than the other group (median: 4 vs 2, respectively, P < 0.01).

Conclusions
The study explored a topic that continues to be underresearched, especially in the Balkans. Prospective studies and comprehensive cognitive batteries are needed to further elucidate the associations between polypharmacy, long-term BZD use, cognitive functioning, and global functioning during maintenance therapy of individuals with PSD.
Toward a neuropsychology of political orientation: exploring ideology in patients with frontal and midbrain lesions
Authors: Nam H. Hannah , Jost John T. , Meager Michael R. , Van Bavel Jay J. 
Published: February 2021

How do people form their political beliefs? In an effort to address this question, we adopt a neuropsychological approach. In a natural experiment, we explored links between neuroanatomy and ideological preferences in two samples of brain lesion patients in New York City. Specifically, we compared the political orientations of patients with frontal lobe lesions, patients with amygdala lesions and healthy control subjects. Lesion type classification analyses revealed that people with frontal lesions held more conservative (or less liberal) beliefs than those with anterior temporal lobe lesions or no lesions. Additional analyses predicting ideology by extent of damage provided convergent evidence that greater damage in the dorsolateral prefrontal cortex—but not the amygdala—was associated with greater conservatism. These findings were robust to model specifications that adjusted for demographic, mood, and affect-related variables. Although measures of executive function failed to mediate the relationship between frontal lesions and ideology, our findings suggest that the prefrontal cortex may play a role in promoting the development of liberal ideology. Our approach suggests useful directions for future work to address the issue of whether biological developments precede political attitudes orvice versa—or both.This article is part of the theme issue ‘The political brain: neurocognitive and computational mechanisms’.
Trust in information, political identity and the brain: an interdisciplinary fMRI study
Authors: Moore Adam , Hong Sujin , Cram Laura 
Published: February 2021

Misinformation has triggered government inquiries and threatens the perceived legitimacy of campaign processes and electoral outcomes. A new identity polarization has arisen between Remain and Leave sympathizers in the UK Brexit debate, with associated accusations of misinformation use. Competing psychological accounts of how people come to accept and defend misinformation pit self-reinforcing motivated cognition against lack of systematic reasoning as possible explanations. We harness insights from political science, cognitive neuroscience and psychology to examine the impact of trust and identity on information processing regarding Brexit in a group of Remain identifiers. Behaviourally, participants' affective responses to Brexit-related information are affected by whether the emotional valence of the message is compatible with their beliefs on Brexit (positive/negative) but not by their trust in the source of information. However, belief in the information is significantly affected by both (dis)trust in information source and by belief compatibility with the valence of the information. Neuroimaging results confirm this pattern, identifying areas involved in judgements of the self, others and automatic processing of affectively threatening stimuli, ultimately supporting motivated cognition accounts of misinformation endorsement.This article is part of the theme issue ‘The political brain: neurocognitive and computational mechanisms’.
The gender-binary cycle: the perpetual relations between a biological-essentialist view of gender, gender ideology, and gender-labelling and sorting
Authors: Saguy Tamar , Reifen-Tagar Michal , Joel Daphna 
Published: February 2021

Gender inequality is one of the most pressing issues of our time. A core factor that feeds gender inequality is people's gender ideology—a set of beliefs about the proper order of society in terms of the roles women and men should fill. We argue that gender ideology is shaped, in large parts, by the way people make sense of gender differences. Specifically, people often think of gender differences as expressions of a predetermined biology, and of men and women as different ‘kinds’. We describe work suggesting that thinking of gender differences in thisbiological-essentialistway perpetuates a non-egalitarian gender ideology. We then review research that refutes the hypothesis that men and women are different ‘kinds’ in terms of brain function, hormone levels and personality characteristics. Next, we describe how the organization of the environment in a gender-binary manner, together with cognitive processes of categorization drive a biological-essentialist view of gender differences. We then describe the self-perpetuating relations, which we termthe gender-binary cycle, between a biological-essentialist view of gender differences, a non-egalitarian gender ideology and a binary organization of the environment along gender lines. Finally, we consider means of intervention at different points in this cycle.This article is part of the theme issue ‘The political brain: neurocognitive and computational mechanisms’.
Visceral politics: a theoretical and empirical proof of concept
Authors: Tsakiris Manos , Vehar Neza , Tucciarelli Raffaele 
Published: February 2021

While the study of affect and emotion has a long history in psychological sciences and neuroscience, the very question of how visceral states have come to the forefront of politics remains poorly understood. The concept ofvisceral politicscaptures how the physiological nature of our engagement with the social world influences how we make decisions, just as socio-political forces recruit our physiology to influence our socio-political behaviour. This line of research attempts to bridge the psychophysiological mechanisms that are responsible for our affective states with the historical socio-cultural context in which such states are experienced. We review findings and hypotheses at the intersections of life sciences, social sciences and humanities to shed light onhowandwhypeople come to experience such emotions in politics and what if any are their behavioural consequences. To answer these questions, we provide insights from predictive coding accounts of interoception and emotion and a proof of concept experiment to highlight the role of visceral states in political behaviour.This article is part of the theme issue ‘The political brain: neurocognitive and computational mechanisms’.
Bringing political psychology into the study of populism
Authors: Rovira Kaltwasser Cristóbal 
Published: February 2021

Although it is true that populism is a contested concept in the social sciences, there is increasing consensus around the use of an ideational definition of populism within the political science literature. This definition has the advantage of providing a clear concept that can be employed to empirically study not only the supply side but also the demand side of the populist phenomenon. Not by chance, an increasing number of scholars are working with a set of survey items to measure the presence and relevance of populist ideas at the mass level, something that is usually conceived of as populist attitudes. Despite the incremental study of populist attitudes in political science, only very limited links with the political psychology literature have been established so far. In this short piece, I address this shortcoming by discussing two avenues for further research on populism that seek to promote much-needed dialogue between comparative politics and political psychology: political identities and conspiracy theories.

AbstractIn medical genetics, discovery and characterization of disease trait contributory genes and alleles depends on genetic reasoning, study design, and patient ascertainment; we now suggest a segmental haploid genetics approach to enhance gene discovery and molecular diagnostics. We present novel genomic insights to enhance discovery in the challenging context of autosomal recessive (AR) traits and bi-allelic variation. We demonstrate computationally that new mutation mediated by nonallelic homologous recombination (NAHR), involving recurrent deletions at 30 genomic regions, likely drives recessive disease burden for over 70% of loci within these segmental deletions or at least 2% of loci genome wide. Meta-analyses of literature-reported patients implicate that NAHR-deletions are depleted from the ascertained pool of AR trait alleles. Exome reanalysis of personal genomes from subjects harboring recurrent deletions uncovered new disease-contributing variants in genes includingCOX10,ERCC6, PRRT2andOTUD7A. Our data demonstrate that genomic sequencing of personal genomes with NAHR-deletions could dramatically foment allele and gene discovery, enhance clinical molecular diagnosis, and could potentially enable human haploid genetics screens as an approach to disease biology.
Patient prioritisation methods to shorten waiting times for elective surgery: a systematic review of how to improve access to surgery
Authors: Rathnayake Dimuthu , Clarke Mike , Jayasinghe Viraj 
Published: February 2021

ABSTRACTBackgroundConcern about long waiting times for elective surgeries is not a recent phenomenon, but it has been heightened by the impact of the COVID-19 pandemic and its associated measures. One way to alleviate the problem might be to use prioritisation methods for patients on the waiting list and a wide range of research is available on such methods. However, significant variations and inconsistencies have been reported in prioritisation protocols from various specialties, institutions, and health systems. To bridge the evidence gap in existing literature, this comprehensive systematic review will synthesise global evidence on policy strategies with a unique insight to patient prioritisation methods to reduce waiting times for elective surgeries. This will provide evidence that might help with the tremendous burden of surgical disease that is now apparent in many countries because of operations that were delayed or cancelled due to the COVID-19 pandemic and inform policy for sustainable healthcare management systems.MethodsWe searched PubMed, EMBASE, SCOPUS, Web of Science, and the Cochrane Library, with our most recent searches in January 2020. Articles published after 2013 on major elective surgery lists of adult patients were eligible, but cancer and cancer-related surgeries were excluded. Both randomised and non-randomised studies were eligible and the quality of studies was assessed with ROBINS-I and CASP tools. We registered the review in PROSPERO (CRD42019158455) and reported it in accordance with the PRISMA statement.ResultsThe electronic search in five bibliographic databases yielded 7543 records (PubMed, EMBASE, SCOPUS, Web of Science, and Cochrane) and 17 eligible articles were identified in the screening. There were four quasi-experimental studies, 11 observational studies and two systematic reviews. These demonstrated moderate to low risk of bias in their research methods. Three studies tested generic approaches using common prioritisation systems for all elective surgeries in common. The other studies assessed specific prioritisation approaches for re-ordering the waiting list for a particular surgical specialty.ConclusionsExplicit prioritisation tools with a standardised scoring system based on clear evidence-based criteria are likely to reduce waiting times and improve equitable access to health care. Multiple attributes need to be considered in defining a fair prioritisation system to overcome limitations with local variations and discriminations. Collating evidence from a diverse body of research provides a single framework to improve the quality and efficiency of elective surgical care provision in a variety of health settings. Universal prioritisation tools with vertical and horizontal equity would help with re-ordering patients on waiting lists for elective surgery and reduce waiting times.
