RESUMO

Urine release (micturition) serves an essential physiological function as well as a critical role in social communication in many animals. Here, we show a combined effect of olfaction and social hierarchy on micturition patterns in adult male mice, confirming the existence of a micturition control center that integrates pro- and anti-micturition cues. Furthermore, we demonstrate that a cluster of neurons expressing corticotropin-releasing hormone (Crh) in the pontine micturition center (PMC) is electrophysiologically distinct from their Crh-negative neighbors and sends glutamatergic projections to the spinal cord. The activity of PMC Crh-expressing neurons correlates with and is sufficient to drive bladder contraction, and when silenced impairs micturition behavior. These neurons receive convergent input from widespread higher brain areas that are capable of carrying diverse pro- and anti-micturition signals, and whose activity modulates hierarchy-dependent micturition. Taken together, our results indicate that PMC Crh-expressing neurons are likely the integration center for context-dependent micturition behavior.

RESUMO

BACKGROUND: Microneedling is used to enhance transcutaneous drug delivery. However, the extent to which microneedling devices impact filler delivery and whether this varies by filler type, microneedling device type, and treatment sequence is not known. OBJECTIVE: To histologically assess and quantify the delivery of commonly used fillers through microneedling, using both a microneedling pen and a microneedling roller. In addition, the authors investigated whether there is a variation in filler delivery based on the sequence of microneedling in relation to topical filler application. METHODS: Ex vivo human abdominal skin samples were subjected to microneedling pen or microneedling roller treatment. Black tissue marking ink, hyaluronic acid, poly-l-lactic acid, or undiluted calcium hydroxyapatite was topically applied before or immediately after microneedling treatment. RESULTS: Histological evaluation revealed a notable presence of black ink within channels formed by both microneedling treatments (15.5%-98.1%), whereas there was limited presence of the various filler types tested (0%-6.6%) in all settings. Topical application before microneedling treatment led to relatively higher filler/ink deposition within the channels formed by the microneedling treatments compared with topical application after microneedling. CONCLUSION: Transcutaneous delivery of fillers was not significantly helped by microneedling treatment, whereas the microneedling devices demonstrated effective delivery of an aqueous solution.

RESUMO

BACKGROUND: This study aims to pioneer in evaluating women's representation in plastic surgery innovations, focusing on mammary prosthesis devices' inventorship. Despite growing gender parity in the field, women's involvement in innovation remains underexplored. This is especially crucial, as the predominant recipients of these innovative technologies are women, urging a necessity for broader female engagement in pioneering surgical advancements. METHOD: Patents under the "A61F2/12: Mammary prostheses and implants" classification between the dates January 1, 2011, to December 31, 2020, were identified using Google Patents Advanced. Inclusion criteria included patents (not designs) in English and applications (not grants), with no litigation limitations. Data collected included ID, title, assignee (categorized as industry, academic, private, individual), inventors, and dates (priority, filing, and publication). Sex of inventors was identified with the literature validated gender API, with manual resolution of unresolved genders or with ga_accuracy scores of less than 75%. Data were analyzed using 2-tailed Student t tests, χ2 analysis, and Pearson correlation coefficient (significance set at P ≤ 0.05). RESULTS: Of the more than 130,000 plastic surgery patents in English identified between the 10-year period, 1355 were classified as A61F2/12. A total of 374 unique patents were included for analysis (841 duplicates were removed, and 140 patents were excluded because of non-English character author names). There was a significant increase in patents over the decade (from 15 in 2011 to 88 in 2020, R2 = 0.74, P < 0.05), with a decrease in number of inventors per patent (R2 = 0.12, P < 0.05). Of the 1102 total inventors, 138 were female (11.2%), with a 4-fold increase in representation over the decade (R2 = 0.58, P < 0.05), including increase in patents filed with a woman first inventor (0%-14.8%). Women were equally likely to be first 3 inventors versus middle to last inventors (12.8% vs 11.1%, respectively). CONCLUSIONS: Over a decade, mammary device innovations rose significantly. Although women inventors' representation improved, it remains disproportionate compared with women in residency/practice. Hence, interventions should aim to align inventor representation with training ratios, through institutional optimization, reducing gender segmentation, and enhancing funding opportunities.

RESUMO

INTRODUCTION: Vascular reconstruction requires technical expertise and is often time consuming. As a novel alternative to traditional hand-sewn vascular anastomoses, the VasoLock (VL), is a nonabsorbable, sutureless anastomosis device with traction anchors designed to hold free artery ends together. These anchors do not penetrate the vessel wall but adhere by leveraging the elasticity of the vessels to fasten blood vessels together. This pilot study assesses the performance and patency of this novel device in a porcine model of femoral artery injury. METHODS: Female swine (n = 7) underwent femoral artery exposure for a total of 10 VL implanted. Study animals underwent hemodilution to a target hematocrit of 15% and ROTEM was used to assess coagulopathy, followed by an arterial injury via transection. The VL was inserted without any sutures. Flow-probe monitors were positioned proximal and distal to the device and flow rates were measured continuously for a total of 90 min. Flow was analyzed and presented as a ratio of distal to proximal flow with the slope of this ratio across time subsequently determined. Angiographic assessment was completed to evaluate for patency and technical complications after 90 min of implant. RESULTS: The average animal weight was 44.1 ± 3.2 kg. The average mean arterial pressure at the time of implant was 51.2 ± 7.8 mmHg, median heart rate was 77.4 (IQR = 77.25-157.4) beats per minute, and average temperature was 36.1 ± 1.5°C. The baseline hematocrit was 13.5 ± 3.0%, average pH was 7.20 ± 0.1, average clotting time was 154.1 ± 58.7 s and average clot formation time was 103.4 ± 10.9 s all demonstrating the acidotic, hypothermic, and coagulopathic state of the swine at the time of insertion. During the 90-min observation period, the average flow gradient identified across the VL was 0.99 ± 0.24, indicating no significant change in flow across the VL. The average slope of the gradients was 0.0005 (P = 0.22), suggesting the ratio of proximal and distal flow did not change over the 90 min. Following 90 min of dwell time, all VL were patent without technical complication. Angiographic assessment at 90 min demonstrated no evidence of dissection, device migration, arterial extravasation, or thromboembolism with any of the 10 devices. CONCLUSIONS: This pilot study demonstrated technical feasibility of the novel VL device over a 90-min observation period. All VL were patent and no negative events or complications were identified. This technology demonstrated significant promise in a coagulopathic state: additional investigation, involving long-term survival, is warranted for further validation.

RESUMO

BACKGROUND: There has been an increasing focus on gender disparities in the medical field and in the field of vascular surgery specifically. We aimed to characterize gender representation in vascular surgery innovation over the past 10 years, using metrics of patents and National Institutes of Health (NIH) support. METHODS: We performed a retrospective review of all vascular-related patent filings (Google Scholar) and NIH-funded grants (NIH RePORTER) over a 10-year period (January 1st, 2012, to December 31st, 2021). Gender-API (Application Programming Interface) was used to identify the gender of the inventors, with manual confirmation of a 10% random sample. Gender representation for patent inventors and grant principal investigators (PIs) were compared using Chi-squared and Student's t-tests as appropriate. Yearly temporal changes in representation were analyzed using Wilcoxon signed-rank tests and linear regression analyses. RESULTS: We identified 2,992 unique vascular device patents with 6,093 associated inventors over 10 years. Women were underrepresented in patent authorship overall (11.5%), and were least likely to be listed as first inventor (8.9%) and most commonly fourth and fifth inventors (15.5% and 14.1%, respectively) compared to men. There was no significant change in representation of women inventors over time (-0.2% females per year, 95% confidence interval (CI) -0.54 to 0.10). We identified 1736 total unique NIH grants, with 23.8% of funded projects having women PIs. There was an increase in the proportion of women PIs over time (+1.31% per year, 95% CI 0.784 to 1.855; P < 0.001). Projects with women PIs received mean total awards that were significantly lower than projects with men PIs ($350,485 ± $220,072 vs. $451,493 ± $411,040; P < 0.001), but the overall ratio of funding:women investigators improved over time (+$11,531 per year, 95% CI $6,167 to $16,895; P = 0.0011). CONCLUSIONS: While we have made strides in increasing the number of women in the surgical research space, there is still room for improvement in funding parity. In addition, we found substantial and persistent room for improvement in representation of women in surgical innovation. As we enter a new frontier of surgery hallmarked by equalizing gender representation, these data should serve as a call-to-action for initiative aimed at rebuilding the foundation of surgical innovations upon equal gender representation.

RESUMO

BACKGROUND: Microsurgery is a foundational plastic surgery principle. However, public unawareness of microsurgery and its associated rigorous training in the United States may contribute to current misconceptions and undervaluing of plastic and reconstructive surgeons. This study aims to characterize public knowledge of microsurgery. METHODS: A cross-sectional survey was conducted from August to September 2021 using Amazon Mechanical Turk to assess baseline public knowledge of microsurgery. A multivariable logistic regression model was constructed to evaluate the association between baseline knowledge and demographic characteristics. Significance was set to a p < 0.05. RESULTS: A total of 516 responses were analyzed. The mean age was 36.7 years (standard deviation, 16.04 years; white, 84%; non-Hispanic, 70%). Of those surveyed, 52% agreed that general surgeons perform microsurgery, while only 28% agreed that plastic and reconstructive surgeons perform microsurgery. When asked if head and neck reconstruction, breast reconstruction, and finger replantation required microsurgery, only 28, 41, and 41% of respondents agreed, respectively. When controlled for sociodemographic factors, Hispanics had significantly more odds to mistake that head and neck reconstruction did not require microsurgery (odds ratio [OR] 95% CI 0.49; 0.30-0.80; p = 0.004) and less odds to consider plastic and reconstructive surgeons for reconstruction (OR 0.51; 95% CI 0.32-0.84; p = 0.008). Females had 1.63 more odds of considering plastic and reconstructive surgeons for reconstruction (95% CI 1.09-2.43; p = 0.017). Low-educated participants had significantly more odds to consider general surgeons as those who performed reconstructive microsurgery (OR 8.70; 95% CI 1.09-69.40; p = 0.041). CONCLUSION: Misconceptions of microsurgery as a foundational principle of plastic surgery persist and correlate with undervaluing the specialty. Knowledge differs by ethnicity, level of education, and gender. Therefore, patient counseling should use culturally appropriate elements to demystify microsurgery, build value, and better inform risks and benefits.

RESUMO

BACKGROUND: Successful intraoperative microvascular anastomoses are essential for deep inferior epigastric perforator (DIEP) flap survival. This study identifies factors associated with anastomotic failure during DIEP flap reconstruction and analyzes the impact of these anastomotic failures on postoperative patient outcomes and surgical costs. METHODS: A retrospective cohort study was conducted of patients undergoing DIEP flap reconstruction at two high-volume tertiary care centers from January 2017 to December 2020. Patient demographics, intraoperative management, anastomotic technique, and postoperative outcomes were collected. Data were analyzed using Student's t-tests, Chi-square analysis, and multivariate logistic regression. RESULTS: Of the 270 patients included in our study (mean age 52, majority Caucasian [74.5%]), intraoperative anastomotic failure occurred in 26 (9.6%) patients. Increased number of circulating nurses increased risk of anastomotic failure (odds ratio [OR] 1.02, 95% confidence Interval [CI] 1.00-1.03, p <0.05). Presence of a junior resident also increased risk of anastomotic failure (OR 2.42, 95% CI 1.01-6.34, p <0.05). Increased surgeon years in practice was associated with decreased failures (OR 0.12, CI 0.02-0.60, p <0.05). Intraoperative anastomotic failure increased the odds of postoperative hematoma (OR 8.85, CI 1.35-59.1, p <0.05) and was associated with longer operating room times (bilateral DIEP: 2.25 hours longer, p <0.05), longer hospital stays (2.2 days longer, p <0.05), and higher total operating room cost ($28,529.50 vs. $37,272.80, p <0.05). CONCLUSION: Intraoperative anastomotic failures during DIEP flap reconstruction are associated with longer, more expensive cases and increased rates of postoperative complications. Presence of increased numbers of circulators and junior residents was associated with increased risk of anastomotic failure. Future research is necessary to develop practice guidelines for optimizing patient and surgical factors for intraoperative anastomotic success.

RESUMO

BACKGROUND: While the goal of facial vascularized composite allotransplantation (FVCA) is to provide patients with improved physical and social function, no study has evaluated layperson perception of social acceptance and perceived career success of patients with FVCA. The purpose of this study was to determine how FVCA changes social acceptance and perceived career success of patients with facial disfiguration. METHODS: Eight hundred fifteen laypersons were surveyed through Mechanical Turk to evaluate their perceptions of patients with FVCA. Respondents were shown facial photographs of patients pre-FVCA, post-FVCA, and matched controls and evaluated these photos on 26 items of perceived social acceptance and career success. Responses were analyzed using descriptive statistics and the Wilcoxon signed-rank test. RESULTS: Both male and female post-FVCA photos were perceived as significantly more socially accepted and professionally successful than their pre-FVCA photos in at least 21 out of 26 items (P < 0.001 for all), but the posttransplant patients scored lower than their control in at least 25 out of 26 items (P < 0.001 for all). Additionally, there were discrepancies in findings based on patient gender. CONCLUSIONS: This study suggests that while FVCA has a significantly positive impact on social acceptance and perceived professional success, it does not fully reinstate these qualities. Furthermore, varying surgical outcomes and/or cognitive biases (such as gender) may impact perceptions of the individual by the public. Our findings suggest a need to standardize practices to better predict and improve outcomes and encourage surgeons to consider patient factors such as gender when planning these procedures.

RESUMO

BACKGROUND: Benchtop microsurgical training models that use digital tools (smartphones, tablets, and virtual reality [VR]) for magnification are allowing trainees to practice without operating microscopes. This systematic review identifies existing microscope-free training models, compares models in their ability to enhance microsurgical skills, and presents a step-by-step protocol for surgeons seeking to assemble their own microsurgery training model. METHODS: We queried PubMed, Embase, and Web of Science databases through November 2020 for microsurgery training models and performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We collected data including training model characteristics (cost, magnification, and components) and outcomes (trainee satisfaction, image resolution, and faster suturing speed). We also conducted a complimentary Google search to identify commercially available microscope-free microsurgical training models or kits not reported in peer-reviewed literature. RESULTS: Literature search identified 1,805 publications; 24 of these met inclusion criteria. Magnification tools most commonly included smartphones (n = 10), VR simulators (n = 4), and tablets (n = 3), with magnification ranging up to ×250 magnification on digital microscopy, ×50 on smartphones, and ×5 on tablets. Average cost of training models ranged from $13 (magnification lens) to $15,000 (augmented reality model). Model were formally assessed using workshops with trainees or attendings (n = 10), surveys to end-users (n = 5), and single-user training (n = 4); users-reported satisfaction with training models and demonstrated faster suturing speed and increased suturing quality with model training. Five commercially available microsurgery training models were identified through Google search. CONCLUSION: Benchtop microsurgery trainers using digital magnification successfully provide trainees with increased ease of microsurgery training. Low-cost yet high magnification setups using digital microscopes and smartphones are optimal for trainees to improve microsurgical skills. Our assembly protocol, "1, 2, 3, Microsurgery," provides instructions for training model set up to fit the unique needs of any microsurgery trainee.

RESUMO

BACKGROUND: Acute myocardial infarction (AMI) is a common cause of hospital admissions, readmissions, and mortality worldwide. Digital health interventions (DHIs) that promote self-management, adherence to guideline-directed therapy, and cardiovascular risk reduction may improve health outcomes in this population. The "Corrie" DHI consists of a smartphone application, smartwatch, and wireless blood pressure monitor to support medication tracking, education, vital signs monitoring, and care coordination. We aimed to assess the cost-effectiveness of this DHI plus standard of care in reducing 30-day readmissions among AMI patients in comparison to standard of care alone. METHODS: A Markov model was used to explore cost-effectiveness from the hospital perspective. The time horizon of the analysis was 1 year, with 30-day cycles, using inflation-adjusted cost data with no discount rate. Currencies were quantified in US dollars, and effectiveness was measured in quality-adjusted life-years (QALYs). The results were interpreted as an incremental cost-effectiveness ratio at a threshold of $100,000 per QALY. Univariate sensitivity and multivariate probabilistic sensitivity analyses tested model uncertainty. RESULTS: The DHI reduced costs and increased QALYs on average, dominating standard of care in 99.7% of simulations in the probabilistic analysis. Based on the assumption that the DHI costs $2750 per patient, use of the DHI leads to a cost-savings of $7274 per patient compared with standard of care alone. CONCLUSIONS: Our results demonstrate that this DHI is cost-saving through the reduction of risk for all-cause readmission following AMI. DHIs that promote improved adherence with guideline-based health care can reduce hospital readmissions and associated costs.

RESUMO

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death worldwide. Despite strong evidence supporting the benefits of cardiac rehabilitation (CR), over 80% of eligible patients do not participate in CR. Digital health technologies (ie, the delivery of care using the internet, wearable devices, and mobile apps) have the potential to address the challenges associated with traditional facility-based CR programs, but little is known about the comprehensiveness of these interventions to serve as digital approaches to CR. Overall, there is a lack of a systematic evaluation of the current literature on digital interventions for CR. OBJECTIVE: The objective of this systematic literature review is to provide an in-depth analysis of the potential of digital health technologies to address the challenges associated with traditional CR. Through this review, we aim to summarize the current literature on digital interventions for CR, identify the key components of CR that have been successfully addressed through digital interventions, and describe the gaps in research that need to be addressed for sustainable and scalable digital CR interventions. METHODS: Our strategy for identifying the primary literature pertaining to CR with digital solutions (defined as technology employed to deliver remote care beyond the use of the telephone) included a consultation with an expert in the field of digital CR and searches of the PubMed (MEDLINE), Embase, CINAHL, and Cochrane databases for original studies published from January 1990 to October 2018. RESULTS: Our search returned 31 eligible studies, of which 22 were randomized controlled trials. The reviewed CR interventions primarily targeted physical activity counseling (31/31, 100%), baseline assessment (30/31, 97%), and exercise training (27/31, 87%). The most commonly used modalities were smartphones or mobile devices (20/31, 65%), web-based portals (18/31, 58%), and email-SMS (11/31, 35%). Approximately one-third of the studies addressed the CR core components of nutrition counseling, psychological management, and weight management. In contrast, less than a third of the studies addressed other CR core components, including the management of lipids, diabetes, smoking cessation, and blood pressure. CONCLUSIONS: Digital technologies have the potential to increase access and participation in CR by mitigating the challenges associated with traditional, facility-based CR. However, previously evaluated interventions primarily focused on physical activity counseling and exercise training. Thus, further research is required with more comprehensive CR interventions and long-term follow-up to understand the clinical impact of digital interventions.

RESUMO

BACKGROUND: In 2018, the Northeastern Society of Plastic Surgeons first Women in Plastic Surgery was established, reflecting the national trend to address the gender gap between men and women in surgery. Conferences, such as the annual NESPS, are important opportunities to increase visibility of female role models and resources to address deterrents to surgical careers. We thus sought to examine the participation and visibility of women in the NESPS over the last decade. METHODS: Abstracts and programs from the NESPS regional conferences between 2013 and 2019 were accessed via the publicly available past meetings archives, and registration lists were provided by the NESPS. Registrants, panelists, speakers, moderators, and first author and senior author listed for each poster presentation, podium presentation was listed, sex was determined (male or female), and sex were aggregated by category of participation. Significance was set at a P value of less than 0.05. RESULTS: Registration of women for the NESPS annual conferences was constant for 5 years (2013-2017), followed by an increase in female registrants from 27.1% in 2017 to 42.3% in 2019. Female representation among poster and podium presentations also increased from 2017 to 2019 (7.7%-23.3% poster presentations and 11.1%-23.4% podium presentations). Invited positions (speakers, panelists, and moderators) had a peak of 32.2% in 2017, but otherwise, there is no clear evidence of improved representation of women. CONCLUSIONS: We found an increase in the proportion of female registrants at the annual NESPS conferences from 2013 to 2019. However, visibility of female participants fluctuated over the same period; addressing this represents one opportunity for closing the gender gap at the NESPS. As the percentage of female trainees continues to rise, we look to female faculty to continue to participate in educational events, such as the NESPS meeting, and to be present as role models for the growing new generation of female plastic surgeons.

RESUMO

ABSTRACT: This study is the first to investigate pediatric craniomaxillofacial (CMF) trauma patients that present with concomitant burns. The authors aim to identify differing etiologies, presentations, facial fracture patterns, interventions, and outcomes between pediatric CMF trauma patients with versus without concomitant burns. In this retrospective cohort study of a tertiary care center between the years 1990 and 2010, concomitant burns were identified among pediatric patients presenting with CMF fractures. Patient charts were reviewed for demographics, presentation, burn characteristics (total body surface area %, location, and degree), imaging, interventions, involvement of child protective services, and long-term outcomes. Data were analyzed using two-tailed Student t tests and chi-square analysis. Of the identified 2966 pediatric CMF trauma patients (64.0% boys; age 7 ±â€Š4.7 years), 10 (0.34%) patients presented with concomitant burns. Concomitant burn and CMF traumas were more likely to be due to penetrating injuries (P < 0.0001) and had longer hospital lengths of stay (13 ±â€Š18.6 versus 4 ±â€Š6.2 days, P < 0.0001). 40% were due to child abuse, 40% due to motor vehicle collisions, and 20% due to house fires. All four child abuse patients presented in a delayed fashion; operative burn care was prioritized and 70% of the CMF fractures were managed nonoperatively. Concomitant burn and CMF trauma is a rare injury pattern in pediatrics and warrants skeletal surveys with suspicious injury patterns. Future research is necessary to develop practice guidelines.

RESUMO

A key metabolic adaptation of some species that face hypoxia as part of their life cycle involves an alternative electron transport chain in which rhodoquinone (RQ) is required for fumarate reduction and ATP production. RQ biosynthesis in bacteria and protists requires ubiquinone (Q) as a precursor. In contrast, Q is not a precursor for RQ biosynthesis in animals such as parasitic helminths, and most details of this pathway have remained elusive. Here, we used Caenorhabditis elegans as a model animal to elucidate key steps in RQ biosynthesis. Using RNAi and a series of C. elegans mutants, we found that arylamine metabolites from the kynurenine pathway are essential precursors for RQ biosynthesis de novo Deletion of kynu-1, encoding a kynureninase that converts l-kynurenine (KYN) to anthranilic acid (AA) and 3-hydroxykynurenine (3HKYN) to 3-hydroxyanthranilic acid (3HAA), completely abolished RQ biosynthesis but did not affect Q levels. Deletion of kmo-1, which encodes a kynurenine 3-monooxygenase that converts KYN to 3HKYN, drastically reduced RQ but not Q levels. Knockdown of the Q biosynthetic genes coq-5 and coq-6 affected both Q and RQ levels, indicating that both biosynthetic pathways share common enzymes. Our study reveals that two pathways for RQ biosynthesis have independently evolved. Unlike in bacteria, where amination is the last step in RQ biosynthesis, in worms the pathway begins with the arylamine precursor AA or 3HAA. Because RQ is absent in mammalian hosts of helminths, inhibition of RQ biosynthesis may have potential utility for targeting parasitic infections that cause important neglected tropical diseases.

RESUMO

PURPOSE OF REVIEW: A healthy lifestyle throughout one's lifespan is the core foundation for both primary and secondary prevention of cardiovascular disease (CVD). Risk-based decisions for pharmacological therapy is added on-top of lifestyle management. Thus, understanding lifestyle-based recommendations is central to CVD prevention. RECENT FINDINGS: In 2018 and 2019, the American Heart Association (AHA) and American College of Cardiology (ACC) published new guidelines for lipid management and primary prevention of cardiovascular disease (CVD), respectively. The European Society of Cardiology (ESC) and European Atherosclerosis Society (EAS) published new guidelines on lipids and diabetes management in 2019. These guidelines provide recommendations on diet and lifestyle for reducing cardiovascular risk. Both encourage heart-healthy diets consistent with Mediterranean, DASH, or healthy vegetarian patterns. Both provide guidance for recommended physical activity levels but acknowledge any physical activity, even less than recommended, is better than inactivity. Although both ACC/AHA and ESC/EAS guidelines have similar approaches to achieve the same goal of CVD prevention, there were some differences between them. SUMMARY: In this review, we discussed similarities and differences between the American and European guidelines to familiarize clinicians with both sets of lifestyle recommendations in an effort to provide best practices in individualized patient-care for CVD prevention.

RESUMO

The rate of cardiovascular disease (CVD) mortality reduction in the United States has plateaued recently, despite the development of novel preventive pharmacotherapies, increased access to care, and healthcare spending. This is largely due to American's poor dietary patterns and practices causing increasing trends in the prevalence of obesity and type 2 diabetes mellitus. For decades, dietary guidelines on 'healthy diets' to reduce CVD risk, grounded in epidemiological research, have been nationally distributed to Americans. In this review, we highlight landmark events in modern nutrition science and how these have framed past and current understandings of diet and health. We also follow the evolution of dietary recommendations for Americans throughout the years, with an emphasis on recommendations aimed to reduce risk for CVD and mortality. Secondly, we examine how the low-fat ideology came to dominate America in the last decades of the 20th century and subsequently contributed to an excess intake of refined carbohydrates which, in the context of an increasingly sedentary lifestyle, may have fueled the obesity epidemic. We then examine the current major evidence-based dietary patterns and specific dietary approaches to reduce CVD risk, reviewing the literature surrounding nutritional components of the heart-healthy diet and discussing the dietary patterns proven most effective for CVD prevention: the Dietary Approaches to Stop Hypertension (DASH) diet, the Mediterranean diet, and the healthy vegetarian diet. Finally, we discuss emerging dietary trends, considerations for nutrition counseling, and future directions within the important field of nutrition, with the ultimate goal of improving vascular health.

RESUMO

BACKGROUND: This study aims to understand how sociodemographic factors influence perceptions of "Brazilian Butt Lift" (BBL), the cosmetic procedure with the highest reported mortality rate, among adult women. We also investigate whether education about risks changes willingness to receive this procedure. METHODS: A Qualtrics© survey including education about BBL was administered on Amazon Mechanical Turk, with inclusion criteria of female sex. RESULTS: Survey data from 489 female participants were included. 78.1% of participants found the BBL mortality rate to be higher than expected. 70.1% of the original 177 willing or neutral participants became unwilling to undergo a BBL after education. Multivariate logistic regression indicated that individuals who were more willing to undergo BBL after education were individuals who have a diagnosis of body dysmorphic disorder (OR 60.5, p = 0.02) or have an acquaintance who received a BBL (OR 230.2, p < 0.01). CONCLUSIONS: Overall, survey participants were less willing to undergo BBL after learning its risks, indicating the critical role of patient education during informed consent. Additionally, individuals who are unhappy with their body shape, or who feel cultural or social pressure to attain a certain body shape, may accept higher levels of risk to improve their looks, suggesting patient motivation for the procedure may limit even the most effective informed consent process. In light of these findings, the surgical community may consider regulating the BBL procedure and improving safety using evidence-based risk reduction techniques. Ensuring that patients fully understand the risks associated with the BBL procedure is critical for both surgeon and patient.

RESUMO

PURPOSE: In pediatric patients with craniomaxillofacial (CMF) trauma, evaluation for cervical spine injury (CSI) is critical, but there are no studies investigating CSI in this unique population. The aim of this study was to measure the frequency of CSI in the pediatric CMF fracture population. MATERIALS AND METHODS: A retrospective cohort study of all pediatric patients who presented to the Johns Hopkins Hospital Emergency Department (Baltimore, MD) with CMF fractures were examined for concurrent CSIs. Patient charts were reviewed for mechanism of injury, type and level of CSI, type and location of CMF fracture patterns, and overall outcome. Data were analyzed for correlation and statistical relevance. RESULTS: A total of 2,966 pediatric patients (1,897 boys [64.0%]; age range, 0 to 15 yr; average age, 7 ± 4.73 yr) were identified from 1990 to 2010 to have CMF fractures. Of these patients, only 5 children were found to have concomitant CSIs (frequency, 0.169%). The frequency of CSI in patients with CMF fracture and deciduous, mixed, and permanent dentition was 0, 0.307, and 0.441%, respectively. Of the 5 identified cases, 4 had concomitant middle-third facial skeletal fracture, 4 had concomitant upper-third cranial skeletal fracture, and 2 had concomitant lower-third cranial skeletal fracture. CONCLUSION: CSIs in pediatric patients with CMF fracture are rare (frequency, 0.169%); this is considerably lower than the reported ranges in adults (3.69 to 24%). No child with deciduous dentition was found to have a CSI. The lack of CSI in deciduous patients with CMF fracture could be explained by the anatomic differences between pediatric and adult cervical spines and supports conservative imaging for children in this age group (level of evidence, III).

RESUMO

The brain processes information from the periphery and regulates visceral and immune activity to maintain internal homeostasis, optimally respond to a dynamic external environment, and integrate these functions with ongoing behavior. In addition to its relevance for survival, this integration underlies pathology as evidenced by diseases exhibiting comorbid visceral and psychiatric symptoms. Advances in neuroanatomical mapping, genetically specific neuronal manipulation, and neural network recording are overcoming the challenges of dissecting complex circuits that underlie this integration and deciphering their function. Here we focus on reciprocal communication between the brain and urological, gastrointestinal, and immune systems. These studies are revealing how autonomic activity becomes integrated into behavior as part of a social strategy, how the brain regulates innate immunity in response to stress, and how drugs impact emotion and gastrointestinal function. These examples highlight the power of the functional organization of circuits at the interface of the brain and periphery.
