Dual catheter and double-lumen cerebrospinal fluid shunt systems with backflow mechanisms.

PURPOSE: We previously developed a novel functional benchtop apparatus to simulate catheter occlusion in vitro utilizing avian vitelline membrane and chalaza to test catheter designs and de-obstruction techniques. Here, we study the integration of double-lumen catheter-mediated backflow in the shunt system assembly and its potential for an in-line de-obstruction of an obstructed ventricular catheter. METHODS: A double-lumen catheter was connected to a standard proximal shunt catheter for all trials. One limb of the double-lumen catheter was connected to the backflow mechanisms and allowed to loop back for fluid access. A micropump and a bi-corporal electromagnetic pump were utilized to provide various degrees of backflow at predetermined intervals. Flow rates were measured after initial occlusion and after implementation of the backflow mechanisms, and degrees of catheter blockage was calculated as a percentage of the unoccluded flow rate. Flow visualization was also used. RESULTS: In baseline blockage of less than 50%, the average occluding agent weighed 0.3-0.6 g with baseline flow rates of 8.5-11.9 mL/min. After 5 min of backflow using a micropump, the degree of blockage was reduced in 50% of trials. Additional backflow for 5 min did not provide further improvements in flow rate. In baseline blockage of greater than 50%, the average occluding agent weighed 0.8-1.3 g with baseline flow rates of 1.1-4.2 mL/min. After 5 min of backflow, the system demonstrated a decreased blockage in 20% of trials; additional backflow for 5 min further improved the flow rate in 40% of the total trials. Only magnetic plates provided enough force to provide pulsatile backflow in the bi-corporal electromagnetic system. CONCLUSIONS: The preliminary results of connecting a standard proximal catheter in series with a double-lumen catheter show a slight change in the percent occlusion from the baseline status several times when the retrograde flow occurred via one limb of the catheter. Additionally, the de-obstruction seems related to the length of the interval of the backflow and the initial percentage occlusion of the proximal catheter. The statistical analysis does not reveal a statistically significant reduction in occlusion in the proximal catheter with either backflow interval.

Prevalence of orofacial pain in individuals with mild cognitive impairment or dementia: A systematic review and meta-analysis.

BACKGROUND: This systematic review investigated the prevalence of orofacial pain in patients with mild cognitive impairment (MCI) or dementia. MATERIALS AND METHODS: The search was conducted in five databases (Medline (Ovid), Embase (Ovid), CINAHL, Scopus and LILACS), in three grey literature sources and in included articles' reference lists. Three independent reviewers performed study selection, quality appraisal and data extraction. The risk of bias was assessed with the National Institutes of Health tool. Prevalence was calculated using the random-effects model. Subgroup analysis and meta-regression were used to explore the heterogeneity of results. RESULTS: The database and grey literature search led to 12 246 results, from which nine studies were included; a further four were selected through citation searching. The total sample comprised 6115 patients with dementia and 84 with MCI. All studies had high risk of bias. The overall estimated pooled prevalence of orofacial pain among dementia participants was 19.0% (95% CI, 11.0%-27.0%; I2 , 97.1%, P < .001). Only one study included MCI participants, among which the prevalence of orofacial pain was 20.5%. Subgroup analysis demonstrated that the different sources of diagnosis might explain the heterogeneity. A higher prevalence of orofacial pain was observed in dementia participants aged over 80 years or living in nursing homes. Meta-regression analysis showed a nonlinear relationship between age and the prevalence of orofacial pain. CONCLUSIONS: The pooled data from the primary studies revealed that 2 out of 10 patients with dementia have orofacial pain. Further research is needed to clarify the magnitude in individuals with MCI.

The Impact of Breast Cancer Type, Staging, and Treatment on Vascular Complications of Immediate Free-Flap Breast Reconstruction.

BACKGROUND: Patients with advanced cancer staging have a greater risk of developing venous thromboembolism than noncancer patients. The impact of breast cancer stage and treatment on outcomes after autologous free-flap breast reconstruction (ABR) is not well-established. The objective of this retrospective study is to determine the impact of breast cancer characteristics, such as cancer stage, hormone receptor status, and neoadjuvant treatments, on vascular complications of ABR. METHODS: A retrospective review was conducted examining patients who underwent ABR from 2009 to 2018. Breast cancer stage, cancer types, hormone receptor status, and treatments were collected in addition to demographic data. Intraoperative vascular concerns, postoperative vascular concerns, and flap loss were analyzed. Univariate analysis and fixed-effects models were used to associate breast cancer characteristics with outcomes. RESULTS: Neoadjuvant hormone therapy was associated with increased risk for intraoperative vascular concern (odds ratio, 1.059 [ P = 0.0441]). Neoadjuvant trastuzumab was associated with decreased risk of postoperative vascular concern (odds ratio, 0.941 [ P = 0.018]). Breast cancer stage, somatic genetic mutation, receptor types, neoadjuvant chemotherapy, and neoadjuvant radiation had no effect on any vascular complications of ABR. CONCLUSION: Autologous free-flap breast reconstruction is a reliable reconstructive option for patients with all stages and types of breast cancer. There is potentially increased risk of intraoperative microvascular compromise in patients who have neoadjuvant hormone therapy. Trastuzumab is potentially protective against postoperative microvascular compromise. Patients should feel confident that, despite higher stage cancer, they can pursue their desired reconstructive option without fear of vascular compromise.

LGBTQ+ health research guides: a multi-institutional analysis of usage patterns and user information needs.

Objective: LGBTQ+ health research guides can strengthen the LGBTQ+ community through connecting people to quality health services and information, and previous studies have recommended that health sciences libraries create and maintain these guides. Little evidence exists, though, on how these guides are used and how well they meet the needs of LGBTQ+ users. Using retrospective data retrieved from multiple LGBTQ+ health research guides, we examined the categories of LGBTQ+ health information most used, as well as how often guides were accessed. Based on these results, we hope to find patterns which can lead to best practices for libraries. Methods: Five North American academic health sciences libraries contributed select usage data from their LGBTQ+ health research guides, covering a three-year period (July 2018-June 2021). Data was analyzed in two ways. Firstly, the 20 most-clicked resources from each guide were categorized through open coding, to assess if certain information resource categories were more popular among guide users, allowing for inference of user needs. A time-series analysis was also conducted for two sites, using the Classical Seasonal Decomposition by Moving Averages method, to provide deeper insights into the data. Results: Open coding data showed consumer health information resources were used more often than other health resource categories. Resources from more locally based organizations and those with provider and services information were heavily used, indicating that users may be looking for information connecting to local health services and providers. The time series analysis allowed the potential positive effect of guide promotion to be showcased in ways that would not have been clear from the raw data. Conclusion: This study shows that people are accessing LGBTQ+ consumer health information through academic library research guides, with a preference for local information. Guide usage appears to be positively driven by outreach within one's institution and to the greater community. Locating external partners may increase guide impact and provide important links to local resources and services.

Indicators of integrating oral health care within universal health coverage and general health care in low-, middle-, and high-income countries: a scoping review.

BACKGROUND: The World Health Organization (WHO) has recently devoted special attention to oral health and oral health care recommending the latter becoming part of universal health coverage (UHC) so as to reduce oral health inequalities across the globe. In this context, as countries consider acting on this recommendation, it is essential to develop a monitoring framework to measure the progress of integrating oral health/health care into UHC. This study aimed to identify existing measures in the literature that could be used to indicate oral health/health care integration within UHC across a range of low-, middle- and high-income countries. METHODS: A scoping review was conducted by searching MEDLINE via Ovid, CINAHL, and Ovid Global Health databases. There were no quality or publication date restrictions in the search strategy. An initial search by an academic librarian was followed by the independent reviewing of all identified articles by two authors for inclusion or exclusion based on the relevance of the work in the articles to the review topic. The included articles were all published in English. Articles concerning which the reviewers disagreed on inclusion or exclusion were reviewed by a third author, and subsequent discussion resulted in agreement on which articles were to be included and excluded. The included articles were reviewed to identify relevant indicators and the results were descriptively mapped using a simple frequency count of the indicators. RESULTS: The 83 included articles included work from a wide range of 32 countries and were published between 1995 and 2021. The review identified 54 indicators divided into 15 categories. The most frequently reported indicators were in the following categories: dental service utilization, oral health status, cost/service/population coverage, finances, health facility access, and workforce and human resources. This study was limited by the databases searched and the use of English-language publications only. CONCLUSIONS: This scoping review identified 54 indicators in a wide range of 15 categories of indicators that have the potential to be used to evaluate the integration of oral health/health care into UHC across a wide range of countries.

Abdominal Body Contouring: Does Body Mass Index Affect Clinical and Patient Reported Outcomes?

BACKGROUND: Obese individuals are thought to be higher risk for complications after excisional abdominal body contouring (EAC) due to co-morbidities and significant tissue resection. OBJECTIVES: We comparatively analyzed EAC patients with Body Mass Index (BMI) ≥35 kg/m2 and BMI <35 kg/m2 to highlight key differences in clinical and patient-reported-outcomes (PROs). METHODS: Patients ≥18 years-old undergoing EAC by a single surgeon from 01/2018-01/2020 were identified and separated into cohorts based on BMI (<35 and ≥35 kg/m2). Patients were excluded if they had a cosmetic abdominoplasty without history of bariatric surgery or massive weight loss, or if they had <1000 gs of tissue resected. Clinical outcomes and PROs using the BODY-Q were comparatively analyzed. RESULTS: 70 total patients with median BMIs of 30[26-32] and 41[37-45] kg/m2 in each cohort, were identified. Patients with BMI ≥35 kg/m2 were more likely to have higher ASA (P<0.01) and use of incisional negative pressure wound devices (P = 0.042). Alternatively, they were less likely to have had concurrent liposuction (P = 0.05). There were no differences in development of an SSO, SSI or SSOpi (P>0.05) between cohorts. Multivariate logistic regression showed that BMI ≥35 kg/m2, iNPWD and liposuction were not associated with the development of complications. PROs demonstrated improvement in multiple domains despite BMI. CONCLUSION: There was no association with BMI ≥35 kg/m2 and the development of complications within our cohort. We encourage preoperative weight loss when possible, however these procedures can be performed safely with acceptable outcomes even in individuals who are obese and/or require extensive tissue removal.

High-resistance proximal "scaled" ventricular catheters.

PURPOSE: Prove the concept of high-resistance proximal catheters for valve-independent treatment of hydrocephalus. METHODS: A preliminary design process yielded optimal high-resistance proximal ventricular catheters with a "scaled" design and parallel-oriented, U-shaped inlets. Prototypes were manually constructed using carving tools to stamp through silicone tubings. A testing apparatus was developed to simulate cerebrospinal fluid flow through a catheter, and the prototypes were tested against a control catheter for exhibition of an "on/off" phenomenon whereby no flow occurs at low pressures, and flow begins beyond a pressure threshold. Flow distribution was visualized with India ink. Regression analysis was performed to determine linearity. RESULTS: The new designs showed varying amounts of improved flow control with the "scaled" design showing the most practical flow rate control across various pressures, compared to the standard catheter; however, no true "on/off" phenomenon was observed. The "scaled" design showed various degrees of dynamism; its flow rate can be time dependent, and certain maneuvers such as flushing and bending increased flow rate temporarily. Variation in the number of inlets within each "scaled" prototype also affected flow rate. Contrastingly, the flow rate of standard catheters was found to be independent of the number of inlet holes. Ink flow showed even flow distribution in "scaled" prototypes. CONCLUSIONS: This initial feasibility study showed that high-resistance ventricular catheters can be designed to mimic the current/valved system. The "scaled" design demonstrated the best flow control, and its unique features were characterized.

A Systematic Review of Aesthetic Surgery Training Within Plastic Surgery Training Programs in the USA: An In-Depth Analysis and Practical Reference.

BACKGROUND: The importance of aesthetic surgery exposure for plastic and reconstructive trainees has been recently validated by the expansion of case requirements for aesthetic procedures from 50 to 150, as well as resident-driven desire for increased cosmetic exposure throughout training. We aim to systematically review the literature at a national level to report on overall trends in aesthetic surgery training within PRS residencies. METHODS: A literature search of PubMed, Embase, and Scopus identified all English articles published in the USA between 2000 and 2020, using a combination of "aesthetic surgery", "cosmetic surgery", "plastic surgery", "residency and internship", "education", and "training." RESULTS: Our initial search resulted in 415 articles. After review of inclusion and exclusion criteria, in addition to cross-referencing, 41 studies remained, including 15 studies discussing resident and/or program director surveys, eight studies discussing teaching methods, sixteen studies discussing dedicated resident clinics, four studies discussing cosmetic/aesthetic fellowships, three studies discussing cosmetic practice patterns, and eleven studies discussing patient outcomes. CONCLUSION: Current literature demonstrates that there are gaps in aesthetic surgery training for PRS residents in the USA, including facial and neck surgeries and non-surgical interventions. Resident clinics have clear benefits for resident education, without sacrificing patient outcomes. Residency programs should consider the development of a resident cosmetic clinic and/or dedicated cosmetic center to increase surgical exposure and increase trainee comfort in providing this subset of procedures. Published literature is limited in consistency of methods of evaluation, and further in-depth analysis of case volume and diversity at training programs within the USA and internationally is indicated.

Clinical and Patient-Reported Outcomes of 19 Patients Undergoing Clitoral and Labial Reconstruction After Female Genital Mutilation/Cutting.

BACKGROUND: Female genital mutilation/cutting (FGM/C) is the intentional alteration, removal, or injury of female genitalia for non-medical reasons. Approximately 200 million females have been victims of FGM/C, and genital reconstructive procedures are increasing in demand. OBJECTIVES: The objectives of this study were to assess clinical and patient-reported outcomes after FGM/C reconstruction to help guide treatment practices. METHODS: Adult patients undergoing anatomic reconstruction after FGM/C were retrospectively identified. Outcomes included clitoral, labial, and donor site surgical site occurrences (SSO) and the need for revision operations. Patient-reported outcomes were assessed using an adapted version of the Female Sexual Function Index (FSFI), a validated outcomes instrument that assesses sexual function through 6 domains, with each domain having a maximum score of 6. RESULTS: Nineteen patients were identified in our review. Patients presented for reconstruction due to dyspareunia, inability to orgasm, chronic infections, to normalize appearance, and/or to "feel normal." There were no SSOs and two revision operations for adhesions. 74% of patients completed the FSFI postoperatively. Despite most patients seeking repair for inability to orgasm and/or dyspareunia, the median scores for these domains were 4.6 and 5.2. Patients' desire to engage in sexual activity scored lowest (3.9), and patients reported concerns over the appearance of their genitalia (50%) that affected self-confidence (85.7%). CONCLUSION: FGM/C reconstruction is safe and contributes to improvements in physical sexual health. Psychological trauma may contribute to lessened sexual desire and self-confidence even after reconstruction. Multidisciplinary treatment is important to address the long-term psychological effects of this practice.

A Comparative Analysis of Immediate and Delayed-immediate Breast Reconstruction after Postmastectomy Radiation Therapy.

BACKGROUND: Postmastectomy radiation therapy (PMRT) is an important component in the treatment of locally advanced breast cancer. Optimal timing of therapy in relation to autologous breast reconstruction (ABR) remains clinically debated. Herein, we comparatively analyze short- and long-term outcomes between immediate ABR (I-ABR) and delayed-immediate ABR (DI-ABR) in the setting of PMRT. METHODS: Adult patients undergoing ABR with PMRT were separated into cohorts based on reconstructive timeline: I-ABR or DI-ABR. The groups were propensity matched 1:1 by age, body mass index, and comorbidities. Surgical site events and long-term clinical outcomes (readmissions, reoperations, and revision procedures) were collected. Univariate analyses were completed using Pearson's chi-squared tests and Fisher's exact tests, and statistical significance was set at p < 0.05. RESULTS: One hundred and thirty-two flaps (66 in each cohort) were identified for inclusion. Patients with I-ABR were more likely to experience fat necrosis (p = 0.034) and skin necrosis (p < 0.001), require additional office visits (p < 0.001) and outpatient surgeries (p = 0.015) to manage complications, and undergo revision surgery after reconstruction (p < 0.001). DI-ABR patients, however, had a 42.4% incidence of complications following tissue expander placement prior to reconstruction, with 16.7% of patients requiring reoperation during this time. Only one patient (I-ABR) experienced flap loss due to a vascular complication. CONCLUSION: The complications encountered in both of these groups were not prohibitive to offering either treatment. Patients should be made aware of the specific and unique risks of these reconstruction timelines and involved throughout the entire decision-making process. Plastic surgeons should continue to strive to elucidate innovative approaches that facilitate enhanced quality of life without compromising oncologic therapy.

Natural Language Processing in Surgery: A Systematic Review and Meta-analysis.

OBJECTIVE: The aim of this study was to systematically assess the application and potential benefits of natural language processing (NLP) in surgical outcomes research. SUMMARY BACKGROUND DATA: Widespread implementation of electronic health records (EHRs) has generated a massive patient data source. Traditional methods of data capture, such as billing codes and/or manual review of free-text narratives in EHRs, are highly labor-intensive, costly, subjective, and potentially prone to bias. METHODS: A literature search of PubMed, MEDLINE, Web of Science, and Embase identified all articles published starting in 2000 that used NLP models to assess perioperative surgical outcomes. Evaluation metrics of NLP systems were assessed by means of pooled analysis and meta-analysis. Qualitative synthesis was carried out to assess the results and risk of bias on outcomes. RESULTS: The present study included 29 articles, with over half (n = 15) published after 2018. The most common outcome identified using NLP was postoperative complications (n = 14). Compared to traditional non-NLP models, NLP models identified postoperative complications with higher sensitivity [0.92 (0.87-0.95) vs 0.58 (0.33-0.79), P < 0.001]. The specificities were comparable at 0.99 (0.96-1.00) and 0.98 (0.95-0.99), respectively. Using summary of likelihood ratio matrices, traditional non-NLP models have clinical utility for confirming documentation of outcomes/diagnoses, whereas NLP models may be reliably utilized for both confirming and ruling out documentation of outcomes/diagnoses. CONCLUSIONS: NLP usage to extract a range of surgical outcomes, particularly postoperative complications, is accelerating across disciplines and areas of clinical outcomes research. NLP and traditional non-NLP approaches demonstrate similar performance measures, but NLP is superior in ruling out documentation of surgical outcomes.

Persistent Disparities in Postmastectomy Breast Reconstruction and Strategies for Mitigation.

For many women, breast reconstruction is an essential component of the breast cancer care continuum after mastectomy. Despite postmastectomy breast reconstruction now being a standard of care, numerous studies over the past decade have documented persistent racial disparities in breast reconstruction rates, physician referral patterns, and patient knowledge of their reconstructive options. These disparities have disproportionately impacted women of color-most specifically, African American women. Recent data have revealed racial differences in patient comorbidities, informed decision-making satisfaction, and clinical outcomes after breast reconstruction. Explicitly, African American women have significantly more risk factors for complications and less baseline knowledge regarding reconstructive options than white women. With a recent heightened attention focused on social determinants of health, studies designed to improve these racial differences have demonstrated promising results through educational outreach to underserved communities, implementation of tailored legislation promoting inclusion, diversity, and equity, and encouragement of additional recruitment of ethnically underrepresented-in-medicine surgeons. This study uses a targeted review of the literature to provide a summary of racial disparities in breast reconstruction for African American women, with our perspective on opportunities for improvement.

Leaders of the Pack: A Comparison of Chairs and Chiefs to Other Surgeons in American Academic Plastic Surgery.

ABSTRACT: Chairs/chiefs of plastic surgery departments/divisions are responsible for directing activities at academic institutions and thus help determine the direction of academic plastic surgery. Other studies have characterized this group but have not shown which characteristics separate them from other surgeons in the field. To study this relationship, a cross-sectional analysis of plastic surgery faculty affiliated with United States residency training programs (n = 99) was initiated. Data were collected from public online websites. Univariate and multivariate logistic regression were used to identify factors independently associated with chairs/chief status. Sub-analyses were performed within Tiers stratified by residency program rank of chair/chief's current institution. Among 943 plastic surgeons, 98 chairs/chiefs were identified. In accordance with prior literature, most are male (89%) and fellowship-trained (62%), and they have a median H-index of 17. Compared to other surgeons, chair/chiefs have more years in practice (odds ratio [OR]: 1.026, confidence interval [CI]: 0.002-0.049, P = 0.034), higher H-index (OR: 1.103, CI: 0.048-0.147, P < 0.001), and more citations (OR: 1.000, CI: -0.000 to -0.001, P = 0.006). Chair/chiefs were also more likely to be journal editorial board members (OR: 1.728, CI: -0.033 to 1.127, P = 0.046) and national society/organization presidents (OR: 1.024, CI: 0.008-0.039, P = 0.003). No notable differences were found between department chairs versus division chiefs or across Tiers. Overall, scholarly achievement and significant years of experience distinguish chairs/chiefs in American academic plastic surgery. Criteria for achieving this leadership role may not differ between departments and divisions. Further research is needed to evaluate whether these characteristics translate into more effective leadership.

A Comparative Analysis of Fleur-de-Lis and Traditional Panniculectomy after Bariatric Surgery.

INTRODUCTION: The Fleur-de-Lis panniculectomy (FdL) adds a vertical component to correct complex contour deformities after massive weight loss by addressing supra-umbilical horizontal skin excess which is not addressed with infra-umbilical transverse panniculectomy (TP). We aim to perform a head-to-head comparison of clinical outcomes and patient reported outcomes (PROs) between FdL and TP. METHODS: A retrospective review of patients ≥18 with a history of bariatric surgery undergoing FdL or TP by a single plastic surgeon between 07/01/2015 and 05/31/2020 was conducted. Surgical site occurrences (SSOs) including surgical site infection (SSI), delayed healing, cellulitis, seroma, hematoma, surgical site occurrences requiring procedural intervention (SSOpi), and a composite of other postoperative outcomes were assessed. In addition, patient satisfaction was analyzed using the Body-Q questionnaire across 12 domains. RESULTS: The analysis included 56 patients; 26 and 30 patients who were treated with FdL and TP, respectively. Cohorts were statistically similar in terms of age, gender, BMI, and co-morbid conditions. The overall complication rate was 50% (FdL n = 14 (53.9%), TP n = 14 (46.7%); p = 0.592). On multivariate analysis, pannus weight was associated with the development of SSO (p = 0.04). FdL incision, however, was not an independent risk factor for adverse outcomes. Absolute improvement in PROs was similar in both cohorts across multiple domains. CONCLUSION: FdL showed a comparable safety and efficacy profile to TP when performed in post-bariatric surgery patients, with equivalent improvement in PROs across multiple domains. Preoperative weight loss should be encouraged in this population as pannus weight is an independent risk factor for complications.

"A Sign of Things to Come: Training Research Output Long-Term Scholarship in Academic Plastic Surgery."

BACKGROUNDS: Academic plastic surgery has utilized different methods to promote early involvement of trainees in research. Further analysis is needed to characterize the effects of this early emphasis and their impact on long-term academic contributions to the field. METHODS: In October 2020, a cross-sectional study of 949 faculty from US academic plastic surgery programs was conducted using publicly available websites. Training research output for each surgeon was compared to post-training research output and other metrics measuring sustained career scholarship. RESULTS: Increased training publications (P< 0.0001) and citations (P< 0.0001) were associated with fewer years in practice. 727 surgeons (80.0%) had ≥ 1 research article, and this group proceeded to attain significantly higher mean post-training publications per year (3.04 ± 0.14 vs. 1.45 ± 0.13, P< 0.0001) and citations per year (72.12 ± 5.04 vs. 28.39 ± 3.49, P< 0.0001) compared to the 182 (20.0%) surgeons with no training publications. For individuals, total training publications were positively correlated with post-training publications per year (P< 0.0001), a relationship also observed for citations (P< 0.0001). When controlling for years in practice, increased training publications and/or citations were significantly associated with attaining academic professor track (versus clinical professor track) position, endowed professor status, journal board position, and NIH funding (P< 0.05 for all). CONCLUSIONS: There is a trend of increasing research productivity during plastic surgery training, and increased training output is predictive of attaining multiple measures of career academic achievement. Academic plastic surgery should continue to underscore research participation as a valuable part of the training process.

Hitting the Books: A Nationwide Analysis of Advanced Degrees in Academic Plastic Surgery Faculty.

OBJECTIVE: Plastic surgery is one of the most competitive and innovative fields in medicine. The role of the academic plastic surgeon continues to grow beyond clinical care, and many surgeons have pursued advanced degrees (AD) to expand their professional skillset. We present an analysis of ADs of academic plastic surgery faculty in the USA, with consideration of timing of AD attainment. METHODS: All academic plastic surgery faculty members were identified from plastic surgery program websites, as recognized by the American Council of Academic Plastic Surgeons. ADs were defined as additional degrees beyond the primary medical degree. Outcomes included timing of AD attainment, residency rankings, institutional standings, and research productivity. RESULTS: 949 faculty members were identified, and 167 had ADs. The most common ADs were PhD (30%), MS/MSc (18%), and MBA/EMBA (17%). Timing of AD attainment was available for 146 faculty members (84.7%). Having an AD before residency was associated with matching into higher-tiered and integrated residency programs (both p < 0.05). For attending physicians, having an AD was associated with more journal editorial board positions, more publications, higher H-index, receiving NIH funding, and median number of NIH grants (adjusted for years in practice, all p<0.05). Institutional analysis revealed that employing more faculty with an AD was associated with having an integrated residency program, higher residency research ranking, and higher tier integrated residency (all p < 0.05). CONCLUSION: ADs are growing in popularity in academic plastic surgery and are temporally associated with specific advantages in terms of residency placement, research productivity, and institutional standing. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable. This excludes Review Articles, Book Reviews, and manuscripts that concern Basic Science, Animal Studies, Cadaver Studies, and Experimental Studies.

What do we know about portable dental services? A scoping review.

BACKGROUND: Delivering dental care to patients in their home or residential institutions is known as "portable dentistry". The demand for portable dental services is on the rise, but dentists remain reluctant to adopt portable practices. OBJECTIVES: To explore the literature on portable dental services and understand (a) the process of planning and delivering portable dental services and (b) the benefits and challenges of portable dentistry for service providers and patients. METHODS: A systematic scoping search was conducted. We retrieved 3994 documents, 28 of which were included in the final synthesis. Three authors read the papers and conducted thematic content analyses independently. RESULTS: We present a synthesis of the literature and proposed a model of portable dentistry containing three levels with the patient is at the centre surrounded by concentric rings representing the dentist (dental team) and society. At each of these levels, our model is further subdivided into three components: 1) organisation of the service; 2) arrival and set-up of the service; and 3) delivery of the service. In addition, each level includes 1) human factors, which are related either to the dental professional or the patient; 2) non-human factors, which refer to either the equipment or the physical environment; and 3) financial factors, which are related to cost and remuneration. CONCLUSIONS: We propose a model for portable dentistry that dentists and dental educators interested in this practice should find useful.

Assessing Disparities in Reduction Mammaplasty: There Is Room for Improvement.

BACKGROUND: Racial and socioeconomic disparities in access and quality of surgical care are well documented in many surgical subspecialties, including plastic surgery. OBJECTIVES: The authors aimed to determine if demographic disparities exist in preoperative and postoperative satisfaction after breast reduction mammaplasty, utilizing patient-reported quality of life (QoL) scores. METHODS: Patients who underwent breast reduction mammaplasty between 2015 and 2020 were identified. Patients who underwent complex concomitant procedures were excluded. Patient demographics and QoL, as measured by the BREAST-Q, were extracted. Wilcoxon Rank Sum and Kruskal-Wallis tests were employed to compare QoL scores across demographic subgroups. RESULTS: A total of 115 patients met the inclusion criteria. QoL improved across all 4 BREAST-Q domains (all P < 0.001). Disparities were shown to exist in the following: median income vs postoperative satisfaction with information (P < 0.001), BMI vs preoperative physical well-being (P < 0.001), and ethnicity vs preoperative physical well-being (P = 0.003). A sub-group analysis of Caucasian patients compared with Black/African American patients revealed significant inequalities in BMI (P < 0.001), median income by zip code (P < 0.001), improvement in satisfaction with breasts (P = 0.039), satisfaction with information (P = 0.007), and satisfaction with office staff (P = 0.044). CONCLUSIONS: Racial and socioeconomic inequalities exist in preoperative and postoperative satisfaction for patients undergoing breast reduction mammaplasty. Institutions should focus on developing tools for equitable and inclusive patient education and perioperative counseling.

Mechanically stimulated ATP release from mammalian cells: systematic review and meta-analysis.

Body tissues are exposed to a complex mechanical environment, which is perceived by cells and converted to biochemical signals such as ATP release. We performed a meta-analysis of 278 systematically identified studies that investigated mechanically stimulated ATP release (MSAR) to quantify the amounts, kinetics and mechanisms of ATP release under normal and pathological conditions. Mechanically stimulated mammalian cells were shown to release 38.6 [95% confidence interval (CI): 18.2-81.8] amol ATP/cell on average with a characteristic time constant of 32 s (95% CI: 16-66). Analysis of ATP release mechanisms revealed the existence of conserved and tissue-specific release routes. We assessed ATP release in pathophysiological states, and found that ATP release was elevated in inflammation and injury, and attenuated in hereditary (such as cystic fibrosis) and metabolic (such as type II diabetes) conditions. Our study links cell-specific ATP release mechanisms to pathophysiological changes in ATP release and allows ATP release-targeting interventions to be mapped to site-specific effects. This work demonstrates that quantitative synthesis of basic research can generate non-trivial hypotheses and inform evidence-driven translational studies.

Patient-Reported Outcomes of Metal and Acrylic Resin Removable Partial Dentures: A Systematic Review and Meta-Analysis.

PURPOSE: Metal removable partial dentures (RPDs) are often considered long-term treatment options for partially edentulous patients, while acrylic resin RPDs are considered interim treatments. The aim of this review was to compare metal and acrylic resin RPDs regarding patient-reported outcomes for partially edentulous individuals. MATERIALS AND METHODS: Four databases (MEDLINE, EMBASE, CENTRAL, and Web of Science) were systematically searched for observational studies and randomized controlled trials comparing patient-reported outcomes between metal and acrylic resin RPDs. The primary outcome was patient satisfaction. Included studies were assessed for risk of bias using the Cochrane risk of bias in nonrandomized studies of interventions tool (ROBINS-I) and the Cochrane Collaboration Risk of Bias Tool for Randomized Controlled Trials. The level of evidence was evaluated using Oxford Center for Evidence-based Medicine tool. A random-effects model was used to analyze the data. RESULTS: A total of 15 studies were included in the systematic review; 10 in the meta-analysis. The pooled effect size for patient satisfaction and oral health-related quality of life showed no statistical significant difference between metal and acrylic resin dentures (0.22, 95% confidence interval -0.01, 0.45, p = 0.06; 1.45, 95% confidence interval -2.43, 5.33, p = 0.46, respectively). Compliance with using RPDs was significantly higher in patients with metal compared to patients with acrylic resin dentures (pooled odds ratio = 0.57, 95% confidence interval 0.45, 0.73, p < 0.001). Most studies had critical to serious risk of bias and low level of evidence. CONCLUSIONS: The reviewed studies showed that there was no significant difference between metal and acrylic resin RPDs in patient satisfaction and oral health-related quality of life. Metal dentures were associated with higher patient compliance rates and were preferred more by patients compared to acrylic resin dentures. However, the reviewed studies had low levels of evidence and therefore, high-quality randomized controlled trials are needed to conclusively address the question of this review.
