Investigating Unconscious Race Bias and Bias Awareness Among Vascular Surgeons.

Background: Implicit bias can influence behavior and decision-making. In clinical settings, implicit bias may influence treatment decisions and contribute to health disparities. Given documented Black-White disparities in vascular care, the purpose of this study was to examine the prevalence and degree of unconscious bias and awareness of bias among vascular surgeons treating peripheral artery disease (PAD). Methods: The sampling frame included all vascular surgeons who participate in the Vascular Quality Initiative (VQI). Participants completed a survey which included demographic questions, the race implicit association test (IAT) to measure magnitude of unconscious bias, and six bias awareness questions to measure conscious bias. The magnitude of unconscious bias was no preference; or slight, moderate, or strong in the direction of pro-White or pro-Black. Data from participants were weighted to account for nonresponse bias and known differences in the characteristics of surgeons who chose to participate compared to the full registry. We stratified unconscious and conscious findings by physician race/ethnicity, physician sex, and years of experience. Finally, we examined the relationship between unconscious and conscious bias. Results: There were 2,512 surgeons in the VQI registry, 304 of whom completed the survey, including getting IAT results. Most participants (71.6%) showed a pro-White bias with 73.0% of this group in the moderate and strong categories. While 77.5% of respondents showed conscious awareness of bias, of those whose conscious results showed lack of awareness, 67.8% had moderate or strong bias, compared to 55.7% for those with awareness. Bias magnitude varied based on physician race/ethnicity and years of experience. Women were more likely than men to report awareness of biases and potential impact of bias on decision-making. Conclusions: Most people have some level of unconscious bias, developed from early life reinforcements, social stereotypes, and learned experiences. Regarding health disparities, however, these are important findings in a profession that takes care of patients with PAD due to heavy burden of comorbid conditions and high proportion of individuals from structurally vulnerable groups. Given the lack of association between unconscious and conscious awareness of biases, awareness may be an important first step in mitigation to minimize racial disparities in healthcare. CLINICAL PERSPECTIVE: What is new?: This is the first study to examine unconscious and conscious bias in vascular surgeons, an important population for treating peripheral artery disease which disproportionately affects structurally vulnerable groups.We found that the majority of vascular surgeons show a pro-White bias, there is a lack of association between unconscious bias and conscious awareness of bias, and those who do not report conscious awareness of bias may also show greater magnitude of unconscious bias.What are the clinical implications?: These findings offer important considerations for attentiveness to both unconscious biases and enhancement of awareness of the existence of biases among a surgery community that provides care to a diverse population of patients with PAD and disparities in health outcomes.Incorporating information on the awareness of biases and structural changes to facilitate behavior change based on these findings may be helpful within training programs for vascular surgeons.With awareness as an important first step in mitigation, cognizance of the existence of biases, as identified by this study, can aid in efforts to minimize racial disparities in health care.

Sex differences in outcomes of exercise therapy for patients with intermittent claudication: A scoping review.

Exercise therapy is first-line treatment for intermittent claudication due to peripheral artery disease. We sought to synthesize the literature on sex differences in response to exercise therapy for the treatment of intermittent claudication due to peripheral artery disease. A scoping review was performed (1997 to 2023) using Ovid MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Embase, SPORTDiscus, and Web of Science. Articles were included if they were a scientific report of any measures of health-related quality of life or walking performance after an intervention that included a structured walking program. Of the 13 studies, 11 included measures of walking distance; 7 included measures of walking time, 5 included measures of walking speed, and 4 included quality of life measures. Overall, exercise therapy resulted in significant improvements across most measures of walking performance for both men and females. When comparing magnitudes of outcome improvement by sex, results of walking-based measures were contradictory; some studies noted no difference and others found superior outcomes for men. Results of quality of life-based measures were also contradictory, with some finding no difference and others reporting substantially more improvement for females. Both men and females experienced considerable improvement in walking performance and quality of life with exercise therapy. Evidence regarding the differential effect of exercise therapy on outcomes by sex for intermittent claudication is limited and contradictory. Further efforts should be directed at using standardized interventions and metrics for measuring the outcomes that match the indications for intervention in these patients to better understand the expected benefits and any variance according to sex.

Rehabilitation of Dentofacial Asymmetry Secondary to Unilateral Temporomandibular Joint Ankylosis with Dual Distraction and Fixed Orthodontics - Stability at Three-year Follow-up.

Optimal rehabilitation of asymmetric dentofacial deformity secondary to unilateral temporomandibular joint (TMJ) ankylosis is often a challenge. The purpose of this case series is to present an insight into esthetic, occlusal and functional rehabilitation of two patients with varying degree of asymmetric Class II dentofacial deformities secondary to long-standing unilateral TMJ ankylosis. The patients were treated with one-stage surgical protocol employing simultaneous dual distraction technique along with interpositional arthroplasty. Dual distraction technique entailed the simultaneous use of two distractors which allowed for proper control of proximal condylar segment during the course of distraction and lowering the risk of ankylosis recurrence. Thereafter, comprehensive fixed orthodontic mechanotherapy involving the use of temporary anchorage devices was instituted to align and level the compensated dentition. Post-treatment records showed significant improvements in skeletal disharmony and functional stability with good functional occlusion. At the three-year follow-up, the morphological and functionally acceptable results were reasonably well-maintained, with no signs of relapse. Through the two cases reported here, we would like to highlight that one-stage concurrent arthroplasty and dual distraction technique is a safe, stable, and reliable approach for surgical and functional rehabilitation of an adult asymmetric dentofacial deformity secondary to unilateral TMJ ankylosis. Meticulously executed comprehensive orthodontic manipulations involving use of acrylic bite-blocks, elastic traction, and temporary skeletal anchorage device play a crucial role in enhancing the final occlusal outcomes.

Does reducing out-of-pocket costs for children's surgical care protect families from poverty in Somaliland? A cross-sectional, national, economic evaluation modelling study.

OBJECTIVES: An estimated 1.7 billion children around the world do not have access to safe, affordable and timely surgical care, with the financing through out-of-pocket (OOP) expenses being one of the main barriers to care. Our study modelled the impact of reducing OOP costs related to surgical care for children in Somaliland on the risk of catastrophic expenditures and impoverishment. DESIGN AND SETTING: This cross-sectional nationwide economic evaluation modelled several different approaches to reduction of paediatric OOP surgical costs in Somaliland. PARTICIPANTS AND OUTCOME MEASURES: A surgical record review of all procedures on children up to 15 years old was conducted at 15 surgically capable hospitals. We modelled two rates of OOP cost reduction (reduction of OOP proportion from 70% to 50% and from 70% to 30% reduction in OOP costs) across five wealth quintiles (poorest, poor, neutral, rich, richest) and two geographical areas (urban and rural). The outcome measures of the study are catastrophic expenditures and risk of impoverishment due to surgery. We followed the Consolidated Health Economic Evaluation Reporting Standards. RESULTS: We found that the risk of catastrophic and impoverishing expenditures related to OOP expenditures for paediatric surgery is high across Somaliland, but most notable in the rural areas and among the poorest quintiles. Reducing OOP expenses for surgical care to 30% would protect families in the richest wealth quintiles while minimally affecting the risk of catastrophic expenditure and impoverishment for those in the lowest wealth quintiles, particularly those in rural areas. CONCLUSION: Our models suggest that the poorest communities in Somaliland lack protection against the risk of catastrophic health expenditure and impoverishment, even if OOP payments are reduced to 30% of surgical costs. A comprehensive financial protection in addition to reduction of OOP costs is required to prevent risk of impoverishment in these communities.

A Modified Hyrax Assembly for Intrusion of a Traumatically Extruded Incisor: An Innovative Technique.

This case report demonstrates an innovative technique involving concomitant correction of a traumatic extrusive luxated tooth, the mobility of which was being aggravated by anterior occlusal contacts, along with transverse rapid maxillary expansion to capitalize on the advantage of residual growth and simplify the need for comprehensive fixed orthodontic appliance. By incorporating a molar tube into the acrylic splint of the bonded Hyrax expander adjacent to the buccal surfaces and parallel to the buccal cusps of the maxillary first molars, effective intrusion of traumatically extruded upper incisor was achieved concomitantly using a modified intrusion arch during the passive stabilization period after expansion, thereby reducing treatment time. This enabled the immediate correction of extruded tooth and reduced the overall treatment duration and the complexity of post-expansion fixed mechanotherapy, improving compliance and uplifting the self-esteem of the patient. The modified bonded Hyrax assembly can serve as a versatile interim appliance for the simultaneous management of a variety of orthodontic problems such as crowding, spacing, and incisor proclination without compromising the basic integrity of the bonded assembly.

Interceptive orthodontic management of mandibular lateral incisor-canine transposition using simplified and efficient biomechanical approach: A case report.

PURPOSE: Ectopic eruption anomaly, manifesting as tooth transposition, often presents a complex therapeutic challenge. Mandibular lateral incisor- canine transposition, although observed with rarity, tends to have major impact on development of proper dentition and adversely influence physical, nutritional, aesthetic and overall psychosocial well being of the patient. This report chronicles individualized one-phase orthodontic management of the case of incomplete transposition between mandibular right lateral incisor and canine in a 9-year-old boy during mixed dentition period. METHODS: Interceptive orthodontic treatment was initiated with placement of 2×4 fixed appliance in lower arch. A combination of continuous arch wire technique involving the use of improved superelastic nickel-titanium wire in conjunction with TMA rectangular wire loop was utilized to achieve biomechanically efficient mesial movement of mandibular lateral incisor. Treatment continued with sequential bonding of brackets to the rest of the mandibular dentition until the levelling and alignment of the buccal segment dentition was achieved. RESULTS: Well-timed early interceptive treatment involving simplified and controlled movements helped reinstate tooth order, promote free eruption of buccal segment teeth, reduce anchorage burden and achieve predictable and biologically compatible outcome without the use of lingual arch as an additional source of reinforcing anchorage. CONCLUSION: From an aesthetic, occlusal and functional standpoint, the treatment approach used in the reported case and the therapeutic outcome proved to be highly satisfactory. By optimizing the eruption and alignment patterns of the permanent teeth, preadolescent interceptive orthodontic treatment helps mitigate the burden of malocclusion and risks of complex orthodontic treatment in permanent dentition.

Management of skeletal Cl III malocclusion using simultaneous alternate rapid maxillary expansion and constriction (Alt-RAMEC) and facemask protraction in adolescence.

Cl III malocclusion with a significant skeletal component presents a therapeutic challenge during adolescence. This article presents the encouraging results of an individualized two-stage treatment approach adopted for successful nonsurgical correction of severe skeletal Cl III malocclusion in an adolescent girl after the onset of puberty. An orthopedic approach involving simultaneous alternate rapid maxillary expansion and constriction (Alt-RAMEC) protocol and protraction facemask (PFM) therapy was adopted in phase 1 to correct the sagittal skeletal discrepancy. In phase 2, fixed orthodontic therapy aided by the interim use of a modified occlusal settling appliance was undertaken to obtain well-interdigitated occlusion. Meticulously planned and well-executed orthopedic and orthodontic approach, combined with good patient compliance and favorable growth pattern, helped establish well-balanced facial harmony with a proper maxillomandibular relationship and satisfactory overjet and overbite. The results remained stable during the 4-year follow-up. Alt-RAMEC-PFM therapy accompanied by fixed mechanotherapy is a viable option to treat severe skeletal Cl III malocclusion in adolescents.

Sailing through the COVID-19 Pandemic and Beyond: An Evidence-Based Analysis for Dental Healthcare and Practice.

This integrative review aims to provide a consolidated evidence-based appraisal of the most up-to-date guidelines and recommendations of international public and professional health regulatory bodies in relation to preparedness framework for restructuring safe delivery of dental services amid and beyond the coronavirus disease-2019 (COVID-19) pandemic. Most recent updated guidelines for dental professionals from major international health regulatory bodies were reviewed. PubMed, Google Scholar, Cochrane Central Register of Controlled Trials, WHO COVID-19 and LILACS databases, along with relevant preprints were searched, and citations were checked up to January 23, 2021. The search was performed by one author. Shortlisted articles were read and brought to consensus to be included in the study by at least two co-authors. In case of any disagreement between the judgements, an independent co-author's decision was taken as final. Of 849 records searched, 61 articles were included in the study. Following content analysis of the global guidelines and the collected prevailing evidence, the common themes and recommendations of different guidance documents were collated and summarized into seven domains. Most guidelines have a consensus regarding implementation of rigorous administrative, engineering and environmental infection control strategies. However, variations do exist with regard to the use of respirators in non-aerosol-generating procedure (non-AGP) settings, employment of airborne precautions during non-AGPs, use of supplemental air-handling systems, and preoperative use of mouthwashes. This evidence-based analysis can serve as a useful reopening resource tool and facilitate effective restructuring for delivery of optimal, equitable and safe dental practices globally, during and while emerging from the pandemic.

Biometric Assessment of Temporomandibular Disorders in Orthodontics: A Multi-arm Randomized Controlled Trial.

OBJECTIVE: This randomized controlled trial aimed to evaluate the role of fixed orthodontic treatment in the aggravation, precipitation, or alleviation of temporomandibular disorders in young adults. METHODS: Sixty patients were randomly assigned to 4 groups of 15 patients each (group I, orthodontic treatment in temporomandibular disorder-free orthodontic patients; group II, orthodontic treatment in patients with mild symptoms of temporomandibular disorders; group III, splint therapy accompanied by orthodontic treatment in patients with moderate symptoms; and group IV, control with no treatment). The biometric equipment used were the T-scan, to analyze the occlusal component; the BioEMG for muscular analysis; BioJVA for temporomandibular joint acoustic analysis; and JT3D for mandibular kinematic analysis. The paired t-test and ANOVA were used for intragroup and intergroup comparisons, respectively. The difference between groups was assessed using post hoc Tukey's test. RESULTS: Groups I and III showed significant difference in the occlusal, muscular, temporomandibular joint vibration, and kinematic mandibular assessment variables. Group II showed significant improvement in occlusal variables only. Group IV did not show improvement in any of the variables except for certain muscular components. CONCLUSION: Successful practical utilization of biometric equipment revealed that fixed orthodontic treatment does not aggravate temporomandibular disorders. It was also found that temporomandibular disorders due to malocclusion can be treated successfully with orthodontic treatment, whereas temporomandibular disorders due to multifactorial temporomandibular joint and muscular components might require splint therapy before orthodontic intervention.

Aerosol generating procedural risks and concomitant mitigation strategies in orthodontics amid COVID-19 pandemic - An updated evidence-based review.

IMPORTANCE: The ongoing COVID-19 pandemic has posed unique challenges to orthodontic profession by adversely impacting provision of in-office orthodontic care due to prevailing uncertainty around risks pertaining to splatter and 'aerosol-generating procedures' (AGPs). This review aims to provide an insight into the prevailing and emerging evidence informing potential risks related to splatter and AGPs, and risk mitigation strategies employed for reducing the potential risk of SARS-CoV-2 transmission from dental bioaerosols. METHODS: PubMed, Google Scholar, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, LILACS, WHO COVID-19 databases and preprint databases were searched for eligible English language publications. Citation chasing was undertaken up until the review date of 4 January 2021. Study selection, data extraction and risk of bias assessment was undertaken independently in duplicate, or else by consultation with a third author. RESULTS: Following filter application and duplicates removed, a total of 13 articles assessing procedural mitigation measures were included. Seven included studies revealed overall low-risk of bias. The overall risk varied from unclear to high for rest of the studies, with the most concerning domains being blinding of the participants and the personnel and blinding of the outcome assessors. Accumulated consensual evidence points towards the use of dental suction devices with wide bore aspirating tips as effective procedural mitigation strategies. Variations in the literature can be observed concerning aerosol transmission associated with water spray use during debonding. Emerging direct evidence consistently supports adjunctive use of pre-procedural povidone-iodine mouthrinse to mitigate direct transmission risk in the orthodontic practice. CONCLUSIONS: A thorough risk assessment concerning AGPs and implementation of consistent and evidence-based procedural mitigation strategies may play an indispensable role in navigating optimal orthodontic practice through unforeseen similar pandemic threats. High-quality robust research focussing on more biologically relevant models of dental bioaerosols in orthodontic settings is warranted.

Effects of maxillary expansion on hearing and voice function in non-cleft lip palate and cleft lip palate patients with transverse maxillary deficiency: a multicentric randomized controlled trial / Efeitos da expansão maxilar na função auditiva e vocal em pacientes sem fissura labiopalatina e com fissura labiopalatina e deficiência maxilar transversa: um estudo controlado multicêntrico e randomizado

Abstract Introduction The association between the treatment of transverse maxillary deficiency and the recovery of hearing and voice functions has gained attention in recent years. Objective This prospective controlled trial aimed to evaluate the effects of rapid maxillary expansion on hearing and voice function in children with non-cleft lip palate and bilateral cleft lip palate with transverse maxillary deficiency Methods 53 patients (26 non-cleft and 27 bilateral cleft lip palate; mean age, 11.1 ± 1.8 years) requiring rapid maxillary expansion for correction of narrow maxillary arches were recruited for this trial. Eight sub-groups were established based on the degree of hearing loss. Pure-tone audiometric and tympanometric records were taken for each subject at four different time periods. The first records were taken before rapid maxillary expansion (T0), the second after expansion (T1) (mean, 0.8 months), the third after three months (T2) (mean, 3 months) and the fourth at the end of retention period (T3) (mean, 6 months). ANOVA and Tukey HSD post-hoc tests were used for data analysis. Additionally, voice analysis was done using an updated PRAAT software program in a computerized speech lab at T0 and T2. A paired-samplet-test was used for comparisons of mean values of T0 and T2 voice parameters within both groups. Results Rapid maxillary expansion treatment produced a significant increase in the hearing levels and middle ear volumes of all non-cleft and bilateral cleft lip palate patients with normal hearing levels and with mild conductive hearing loss, during the T0-T1, T1-T2, T0-T2, and T0-T3 observation periods (p < 0.05). The significant increase was observed in right middle ear volumes during the T0-T1, T0-T2 and T0-T3 periods in non-cleft patients with moderate hearing loss. For voice analysis, significant differences were observed only between the T0 and T2 mean fundamental frequency (F0) and jitter percentage (p < 0.05) in the non-cleft group. In the cleft group, no significant differences were observed for any voice parameter between the T0 and T2 periods. Conclusion Correction of the palatal anatomy by rapid maxillary expansion therapy has a beneficial effect on both improvements in hearing and normal function of the middle ear in both non-cleft and bilateral cleft lip palate patients. Similarly, rapid maxillary expansion significantly influences voice quality in non-cleft patients, with no significant effect in BCLP patients.

Resumo Introdução A associação entre o tratamento da deficiência maxilar transversa e a recuperação das funções auditivas e vocais ganhou atenção nos últimos anos. Objetivo Avaliar os efeitos da expansão rápida da maxila na função auditiva e vocal em crianças sem fissura labiopalatina e com fissura labiopalatina bilateral com deficiência maxilar transversa. Método Foram recrutados para este estudo 53 pacientes (26 sem fissura e 27 com fissura labiopalatina bilateral; média de 11,1 ± 1,8 anos) que necessitam de expansão rápida da maxila para correção de arcos maxilares estreitos. Oito subgrupos foram estabelecidos com base no grau de perda auditiva. Registros audiométricos e timpanométricos de tons puros foram obtidos para cada indivíduo em quatro períodos. Os primeiros registros foram obtidos antes da expansão rápida da maxila (T0), o segundo após a expansão (T1) (média de 0,8 meses), o terceiro após três meses (T2) (média de 3 meses) e o quarto no fim do período de retenção (T3) (média de 6 meses). Anova e o teste post-hoc de Tukey HSD foram usados para análise dos dados. Além disso, a análise da voz foi feita com um programa PRAAT atualizado em um laboratório de fala computadorizadaem T0 e T2. Foi usado um teste t de amostras pareadas para comparação dos valores médios dos parâmetros de voz em T0 e T2 nos dois grupos. Resultados O tratamento com expansão rápida da maxila produziu um aumento significativo nos níveis auditivos e nos volumes da orelha média de todos os pacientes sem fissura e pacientes com fissura labiopalatina bilateral e níveis auditivos normais e com perda auditiva condutiva leve, durante os períodos de observação T0-T1, T1-T2, T0-T2 e T0-T3 (p < 0,05). Aumento significativo foi observado nos volumes da orelha média direita durante os períodos T0-T1, T0-T2 e T0-T3 em pacientes sem fissura e com perda auditiva moderada. Para a análise de voz, diferenças significantes foram observadas apenas entre a frequência fundamental média T0 e T2 (F0) e a porcentagem de jitter (p < 0,05) no grupo sem fissura. No grupo com fissura, não foram observadas diferenças significantes para nenhum parâmetro de voz entre os períodos T0 e T2. Conclusão A correção da anatomia palatal pela expansão rápida da maxila tem um efeito benéfico tanto na melhoria da audição quanto na função normal da orelha média em pacientes sem fissura e com fissura labiopalatina bilateral. Da mesma forma, a expansão rápida da maxila influencia significativamente a qualidade da voz em pacientes sem fissura, sem efeito significativo em pacientes com fissura labiopalatina bilateral.

Winged nance palatal arch: An adjunct to tooth movement.

Anchorage control during the correction of severely crowded dentitions has always been a source of concern during orthodontic therapy. The Nance palatal arch (NPA) has, in the past, been widely used for reinforcing anchorage in such cases. Modifications of the NPA have been reported for use as a fixed functional appliance or for molar distalization. Herein, a simple, effective modification of the conventional NPA is introduced incorporating two power arms, which can be used for unravelling of anterior crowding at the same time effectively augmenting molar anchorage.

A simplified de novo approach for vector control in facemask therapy.

One of the most common clinical challenges encountered with facemask therapy for early correction of skeletal Class III malocclusions is the delivery of appropriate direction of force for effecting the pure translation of maxilla. This technical note describes a novel method involving the use of Begg's auxiliary for achieving efficient and predictable delivery of protraction forces. With this modified assembly, effective vector control for facemask can be achieved without the need to remove the bonded Hyrax assembly. This chairside modification is an effective and invaluable method for predictable force delivery in facemask therapy.

Interim use of a maxillary lip bumper during interdisciplinary management of ectopically erupted incisor teeth.

INTRODUCTION: Ectopic eruption, manifesting as an aberration in the normal path of eruption of a tooth, can adversely impact facial aesthetics, phonetics and psychosocial development. DESCRIPTION: This case series describes the orthodontic management of two adolescent patients with different clinical presentations of ectopically erupted maxillary central incisors secondary to trauma during the primary dentition period. The therapy primarily included periodontal soft-tissue surgery accompanied by orthodontic traction to align the ectopic incisors. Frenectomy was performed in one patient and surgical excision of a hypertrophied pseudo-pouch in the second patient. A modified maxillary lip bumper was used concomitantly for management of associated soft-tissue trauma, thus facilitating healing and aiding orthodontic traction. RESULTS: Appropriately planned interdisciplinary management involving the interim use of a modified lip bumper allowed proper alignment of the ectopically positioned incisors with a stable outcome at three-year follow-up. CONCLUSION: Fixed orthodontic therapy with concurrent use of modified maxillary lip bumper is an effective approach to treat incisors erupted ectopically in relation to the upper lip and frenum.
