RESUMO
Racial disparities in the prevalence of periodontal disease are consistent and persistent. The epidemiology of periodontal disease demonstrates racial inequities: non-Hispanic Black (14.7%), Mexican American (13.4%), and other Hispanic adults (7.8%) experience a higher prevalence of severe periodontal disease than non-Hispanic White adults (5.9%). Epidemiologic and clinical research on periodontal health suffers from the same problem that has plagued the health equity movement, an over emphasis on describing racial inequities coupled with few interventions that reduce racial health inequity. Over the decades that racial inequities in periodontal disease have been observed, many have argued that systemic racism is the fundamental driver of racial health inequity. This paper interrogates the roles of systemic racism, dental education, clinical treatment, and patient behavior in periodontal disease. We describe how, together, these mechanisms contribute to racial disparities in periodontal outcomes. However, it is insufficient for oral health equity scientists to only describe and discuss the negative effects of systemic racism. The imperative is to create antiracist strategies designed to eliminate systemic racism. Health equity scientists must also specify how dental systems operate in a racist manner and create effective clinical strategies designed to reduce racial disparities in periodontal disease.
RESUMO
Cyanobacteria are simple, efficient, genetically-tractable photosynthetic microorganisms which in principle represent ideal biocatalysts for CO2 capture and conversion. However, in practice, genetic instability and low productivity are key, linked problems in engineered cyanobacteria. We took a massively parallel approach, generating and characterising libraries of synthetic promoters and RBSs for the cyanobacterium Synechocystis sp. PCC 6803, and assembling a sparse combinatorial library of millions of metabolic pathway-encoding construct variants. Genetic instability was observed for some variants, which is expected when variants cause metabolic burden. Surprisingly however, in a single combinatorial round without iterative optimisation, 80% of variants chosen at random and cultured photoautotrophically over many generations accumulated the target terpenoid lycopene from atmospheric CO2, apparently overcoming genetic instability. This large-scale parallel metabolic engineering of cyanobacteria provides a new platform for development of genetically stable cyanobacterial biocatalysts for sustainable light-driven production of valuable products directly from CO2, avoiding fossil carbon or competition with food production.

BACKGROUND: There is a wide range of social media adoption within medical specialties. The use of social media by endocrine surgeons has not been investigated. We undertook this study to describe the use of social media and other platforms by endocrine surgeons. MATERIALS AND METHODS: The American Association of Endocrine Surgeons' publicly available website was used to identify practicing endocrine surgeons in the United States. Surgeon demographics and practice characteristics were collected via internet query. Five social media platforms (Facebook, Instagram, Twitter, LinkedIn, YouTube) were investigated for professional accounts. The presence of a non-institutional professional website, an active Healthgrades account, and presence in non-institutional YouTube videos were also queried. One point was assigned for presence on each of the eight platforms. A professional internet presence (PIP) score was calculated. Descriptive statistics were performed on PIP scores to evaluate the relationship between surgeon and practice characteristics and PIP score. RESULTS: A total of 417 endocrine surgeons were studied. LinkedIn (222, 53.2%) and Twitter (110, 26.4%) were the most commonly used platforms. PIP scores were categorized into zero, one, two, and three or more accounts; 26.9% of surgeons had no professional internet presence. Academic surgeons had a significantly different PIP score than community-based surgeons (P < 0.01). There was no significant association between PIP score and surgeon sex, geographic regions, rural versus urban settings, and years of experience. CONCLUSIONS: Self-identified US endocrine surgeons have low professional internet presence. Endocrine surgeons may consider bolstering their professional internet presence to disseminate medical information.

INTRODUCTION: Thyroidectomy and parathyroidectomy are relatively safe procedures, with overall morbidity rates of 2%-5%. The increasing age is associated with higher likelihood of poor outcomes. The modified five-point frailty index (mFI-5) is associated with complications, but many surgeons are unfamiliar with mFI-5. We assessed the accuracy of the mFI-5 versus the commonly-used American Society of Anesthesiologists (ASA) classification to predict complications following thyroidectomy and parathyroidectomy. METHODS: Patients undergoing thyroidectomy or parathyroidectomy in 2015-2018 NSQIP datasets were identified. The mFI-5 scores were calculated by adding the number of the following comorbidities: congestive heart failure, hypertension requiring medication, chronic obstructive pulmonary disease, diabetes, and nonindependent functional status. Receiver operating characteristics curves were plotted for 30-d mortality and serious morbidity (defined as deep surgical site infection, dehiscence, unplanned intubation, failure to wean from the ventilator 48-h postoperatively, acute renal failure, pneumonia, pulmonary embolism, myocardial infarction, cardiac arrest requiring cardiopulmonary resuscitation, sepsis, septic shock, cerebrovascular accident, or reoperation) using mFI-5 and ASA classification. Areas under these curves (AUC) were compared. RESULTS: Ninety-two thousand, six hundred and ninety-one patients were studied. The mFI-5 and ASA were fair predictors of 30-d mortality (AUC 0.75 and 0.82, respectively) and good predictors of serious morbidity (AUC 0.61 and 0.64). After stratification by age, ASA was superior to mFI-5 in predicting mortality for patients aged 65, 70, 80 y, and older, for the entire population and for thyroidectomy and parathyroidectomy separately. CONCLUSIONS: The ASA classification is a better predictor of mortality and serious morbidity than mFI-5 among patients undergoing thyroidectomy or parathyroidectomy and may be a better prognostic indicator to use when counseling patients before low-risk neck surgery.

BACKGROUND: Patients with psychiatric diagnoses are at greater risk for traumatic injury than the general population. Current literature fails to characterize how premorbid behavioral health disorders (BHDs) complicate craniofacial trauma. This study aimed to describe the characteristics and outcomes of patients with premorbid BHD sustaining facial fractures. METHODS: All adults in the 2013-2016 Trauma Quality Improvement Program datasets with facial fractures were identified. Demographics, injury characteristics, fracture patterns, and in-hospital outcomes were compared in patients with and without premorbid BHDs. BHDs included major psychiatric illnesses, alcohol or drug use disorders, attention deficit hyperactivity disorder, or dementia. RESULTS: Twenty-five percent of the 240,104 subjects with facial fractures had at least one premorbid BHD. Assault (29.9% versus 23.9%, P< 0.001), self-inflicted injury (2.9% versus 1.2%, P< 0.001), and multiple facial fractures (40.2% versus 38.7%, P< 0.001) were more common among the BHD group. The BHD group displayed significantly higher rates of nearly all in-hospital complications, including pneumonia (4.3% versus 3.3%, P< 0.001), substance withdrawal (3.9% versus 0.3%, P< 0.001), unplanned intubation (1.5% versus 0.9%, P< 0.001) and unplanned transfer to the intensive care unit (ICU, 1.3% versus 0.8%, P< 0.001). BHD was strongly predictive of pneumonia, unplanned intubation, and unplanned ICU admission in multivariate analyses. CONCLUSIONS: Patients with BHD represent a subset of facial trauma characterized by different mechanisms and patterns of injury and premorbid health status. BHDs are associated with higher in-hospital complication rates and resource utilization. Understanding the relationship between craniofacial trauma and premorbid BHD creates opportunities to improve morbidity and resource utilization in this group.

BACKGROUND: Many low-risk patients receive preoperative laboratory testing (PLT) prior to elective outpatient surgery, with no effect on postoperative outcomes. This has not been studied in patients undergoing anorectal surgery. The aim of this study was to determine if PLT in this population was predictive of perioperative complications. MATERIALS AND METHODS: The 2015-2018 National Surgical Quality Improvement Program (NSQIP) databases were queried for elective ambulatory anorectal surgeries. PLT was defined as chemistry, hematology, coagulation, or liver function studies obtained ≤30 days preoperatively. American Society of Anesthesiologists (ASA) class 1 and 2 patients were included who underwent elective, ambulatory, benign anorectal surgery. Patient demographics, comorbidities, and postoperative outcomes were compared between those who did and did not receive PLT. Postoperative outcomes were defined as wound-related, procedure-related, major complications, unplanned readmission, and death occurring within 30 days. Multivariate regression analysis determined patient characteristics predictive of receiving testing. RESULTS: Of 3309 patients studied, 48.6% received PLT. On multivariate analysis, older age, female sex, Black race, ASA class 2, and comorbidities were predictive of receiving testing. The complication rates were similar between patients who did and did not receive testing (4.3% versus 3.5%, P = 0.22). CONCLUSIONS: PLT is performed in over half of low-risk patients receiving elective anorectal surgery. There was no difference in the rate of postoperative complications between patients who received testing or not, nor with normal versus abnormal results. PLT can be used more judiciously in this population.

BACKGROUND: Sternal wound infections are a rare but life-threatening complication of cardiothoracic surgery. Prior literature has supported the use of negative pressure wound therapy to decrease sternal wound infections and promote healing. This study sought to determine whether closed incision negative pressure therapy reduced wound infection and improved outcomes in cardiothoracic surgery. METHODS: A retrospective cohort study was performed including all adult patients who underwent nontraumatic cardiothoracic surgery at a single institution between 2016 and 2018 (n = 1199). Patient characteristics, clinical variables, and surgical outcomes were compared between those who did and did not receive incisional negative pressure wound therapy intraoperatively. Multivariable logistic regression analysis determined factors predictive or protective of the development of complications. RESULTS: Incisional negative pressure wound therapy was used in 58.9% of patients. Patients who received this therapy were older with statistically higher rates of hyperlipidemia, statin, and antihypertensive use. The use of negative pressure wound therapy was found to significantly reduce rates of both wound infection (3.0% vs 6.3%, P = 0.01) and readmission for wound infection (0.7% vs 2.6%, P = 0.01). After controlling for confounding variables, negative pressure wound therapy was found to be a protective factor of surgical wound infection (odds ratio, 0.497; 95% confidence interval, 0.262-0.945). CONCLUSIONS: In the largest population studied to date, this study supported the expanded use of negative pressure therapy on sternal wound incisions to decrease infection rates.

BACKGROUND: Patients frequently use online physician ratings websites (PRWs) to identify physicians for care. PRWs provide physician information and reviews. However, the accuracy of PRWs is uncertain. We investigated the accuracy and validity of Healthgrades with respect to endocrine surgery. We identified factors associated with reported board certification inaccuracy, higher ratings, greater quantity of ratings. MATERIALS AND METHODS: The search term "endocrine surgery specialist" was used and the search was limited to a 25-mile radius around Philadelphia, PA. Data was collected on physician sex, age, board certification, surgical specialty, quantity of ratings, average rating, response to comments, and provision of a self-description. Descriptive statistics were performed to examine surgeon characteristics, ratings, and reported board certifications. Board certification accuracy was determined by searching the corresponding American Board website and calculating a kappa statistic. Logistic regression was performed to identify factors associated with board certification inaccuracy, higher average ratings, and higher quantity of ratings. RESULTS: A total of 300 physicians were identified. Eighty-four percent of listed board certifications were accurate; the kappa statistic for accuracy of board certification was 0.634. Providing a response to comments and greater quantity of ratings were associated with higher average ratings. Provision of a self-description, male sex, and younger age were identified as factors associated with higher quantity of ratings. CONCLUSIONS: A wide range of specialties are identified as endocrine surgery specialists. The reliability of board certification reporting was moderate. Increased surgeon involvement with the Healthgrades site was inconsistently associated with higher average ratings and higher quantity of ratings but lower accuracy.

OBJECTIVE: This systematic review assesses the association of tooth loss (TL), as the exposure, with morbidity and mortality by diabetes mellitus (DM) status, as the outcome, in older adults. BACKGROUND: Individuals with DM have higher prevalence of severe TL and increased risk of developing morbidities and mortality. No systematic review has evaluated the association between TL with morbidity and mortality by DM status. MATERIAL AND METHODS: Comprehensive searches used multiple publication databases containing reports published between 01/01/2000 and 04/21/2021. Two authors independently evaluated included studies for quality and risk of bias using the Critical Appraisal Skills Programme (CASP) checklist for cohort and Center for Evidence-Based Medicine (CEBM) critical appraisal sheet for cross-sectional studies, while a third author arbitrated decisions to resolve disagreements. RESULTS: Thirteen studies met the inclusion criteria: eight cross-sectional and five cohort. Qualitative review of the included studies indicated TL is associated with increased incidence and prevalence of DM. TL is also associated with DM-related morbidities including greater prevalence of heart disease, diabetic retinopathy, metabolic syndrome; poorer health-related quality of life; poorer survival of participants with chronic kidney disease; and increased medical expenditure. Overall, the quality of the evidence reviewed was medium, as per the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence. CONCLUSIONS/PRACTICAL IMPLICATIONS: This review found significant associations of TL with prevalence and incidence of DM and adverse DM-related outcomes. An interprofessional team-care approach that includes an oral health component could benefit the prevention and management of DM.

DNA assembly allows individual DNA constructs or libraries to be assembled quickly and reliably. Most methods are either: (i) Modular, easily scalable and suitable for combinatorial assembly, but leave undesirable 'scar' sequences; or (ii) bespoke (non-modular), scarless but less suitable for construction of combinatorial libraries. Both have limitations for metabolic engineering. To overcome this trade-off we devised Start-Stop Assembly, a multi-part, modular DNA assembly method which is both functionally scarless and suitable for combinatorial assembly. Crucially, 3 bp overhangs corresponding to start and stop codons are used to assemble coding sequences into expression units, avoiding scars at sensitive coding sequence boundaries. Building on this concept, a complete DNA assembly framework was designed and implemented, allowing assembly of up to 15 genes from up to 60 parts (or mixtures); monocistronic, operon-based or hybrid configurations; and a new streamlined assembly hierarchy minimizing the number of vectors. Only one destination vector is required per organism, reflecting our optimization of the system for metabolic engineering in diverse organisms. Metabolic engineering using Start-Stop Assembly was demonstrated by combinatorial assembly of carotenoid pathways in Escherichia coli resulting in a wide range of carotenoid production and colony size phenotypes indicating the intended exploration of design space.

STUDY OBJECTIVES: To examine the current use of routine preoperative laboratory testing in low-risk patients undergoing ambulatory gynecologic surgery and to determine if such testing affects surgical outcomes. DESIGN: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was queried for ambulatory gynecologic surgeries between 2015 and 2018. Low-risk patients included in this study were defined as being American Society of Anesthesiologists class 1 or 2. The rate of preoperative laboratory testing before ambulatory gynecologic surgery in low-risk patients was determined and factors associated with testing including patient characteristics and comorbidities were evaluated. NSQIP-defined complications were compared between those with and without preoperative laboratory testing. Preoperative laboratory testing was defined as chemistry, hematology, coagulation, or liver function studies obtained within 30 days preoperatively. SETTING: National health systems that participate in the NSQIP. PATIENTS: There were 19 855 patients who underwent an ambulatory gynecologic procedure. INTERVENTIONS: Preoperative laboratory testing in low-risk patients before ambulatory gynecologic surgery. MEASUREMENTS AND MAIN RESULTS: Of the 19 855 patients studied, 14 258 (71.8%) received preoperative laboratory testing. Statistically significant differences were seen between patients who underwent preoperative testing and patients who did not. The most frequent preoperative test was a complete blood cell count (70.4%). Among patients who received preoperative testing, 4053 (28.4%) had at least 1 abnormal result. No statistically significant difference was seen in overall postoperative complication rate when comparing patients who received preoperative laboratory testing with those who did not (2.5% vs 2.2%, pâ¯=â¯.30). Specifically, no statistically significant difference was seen among wound complications (1.0% vs 1.0%, pâ¯=â¯.78), major complications (1.0% vs 0.8%, pâ¯=â¯.11), unplanned return to the operating room (0.1% vs 0.2%, pâ¯=â¯.40), unplanned readmission (0.7% vs 0.5%, pâ¯=â¯.10), or overall morbidity (2.1% vs 1.9%, pâ¯=â¯.38). Chi-square analyses were performed to compare categoric variables. Continuous variables were compared using unpaired t tests. CONCLUSION: This large study using a reputable national database revealed that despite updated evidence-based guidelines that recommend against the practice, preoperative laboratory testing continues to be performed for most low-risk patients undergoing ambulatory gynecologic surgery. This study also further supports current guidelines in demonstrating no difference in surgical outcomes between low-risk patients who did and did not receive preoperative laboratory testing. Preoperative laboratory testing practices for low-risk patients undergoing ambulatory gynecologic surgery do not follow current evidence-based guidelines and should be re-evaluated.

The role of contrast-enhanced ultrasound (CEUS) imaging is being widely explored by various groups for its use in the pediatric population. Clinical implementation of new diagnostic or therapeutic techniques requires extensive and meticulous preclinical testing and evaluation. The impact of CEUS will be determined in part by the extent to which studies are oriented specifically toward a pediatric population. Rather than simply applying principles and techniques used in the adult population, these studies are expected to advance and augment preexisting knowledge with pediatric-specific information. To further develop this imaging modality for use in children, pediatric-focused preclinical research is essential. In this paper we describe the development and implementation of the pediatric-specific preclinical animal and phantom models that are being used to evaluate CEUS with the goal of clinical translation to children.

BACKGROUND: Burnout in medicine, and specifically radiology, has been receiving more attention. Little data-driven literature is available regarding risk factors/causes to ultimately help guide the development of potential solutions. OBJECTIVE: To survey pediatric radiologists, a cohort with a documented high prevalence of burnout, and to understand the impact of clinical demands on nonclinical tasks and the implications of burnout on mental health. MATERIALS AND METHODS: A survey of Society for Pediatric Radiology (SPR) North America attendings was performed regarding institutional factors contributing to burnout, including call burden, clinical demands, departmental support and administrative/academic tasks. Questions regarding mental health and wellness resources were also included. Generalized linear modeling assuming binomial distribution was used for analyses with SAS 9.4. RESULTS: The response rate was 305/1,282 (24%) with 53% of respondents female. Respondents reported that both the number and complexity of clinical cases have increased since they first started practice as an attending, while the time for interpretation has not changed, P<0.0001. Using a scale of 0 (never), 1 (rarely), 2 (sometimes), 3 (frequently) and 4 (always), covering multiple hospitals (2.2) and administrative tasks (2.4) were the most stressful job factors. For those in administrative roles, the most stressful job factors were job-related tasks affected teaching duties (2.0) and decreased overall job satisfaction (2.0). Of the respondents, 52% said they know a physician affected by work stress-related mental illness and 25% know a physician who has contemplated or committed suicide. While 39% of the respondents have resources available to address burnout, only 33% utilize these resources. CONCLUSION: Increasing clinical demands and additional institutional/departmental factors play a potential role in burnout, which has serious implications for the mental health of pediatric radiologists.

Multiple analytical and preclinical studies were performed to compare the biochemical characteristics, pharmacokinetics (PK), safety and neoantigenicity of a new 5% liquid formulation of Alpha-1 Proteinase Inhibitor (Liquid A1PI, Prolastin®-C Liquid) with the lyophilized version (Lyophilized A1PI, Prolastin®-C). Liquid A1PI and Lyophilized A1PI had similar average mass (~52 kDa), and both forms exhibited glycoform patterns consistent with the known banding pattern of A1PI (dominated by the M6 and M4 bands, including deconvoluted masses). Both Liquid A1PI and Lyophilized A1PI yielded average percent purity values ranging from 96% to 99% and had active content ranging from 53⯠mg/mL to 59 â¯mg/mL. The PK profile of Liquid A1PI was similar to Lyophilized A1PI. Safety assessments in rabbits showed good tolerability and no test article-related changes in mortality, clinical signs, clinical pathology, body weight, food consumption, or urinalysis parameters. Following immunodepletion of antibodies that recognize Lyophilized A1PI, there were no significant differences in the anti-drug titers among animals immunized with Lyophilized A1PI and Liquid A1PI (pâ¯>â¯0.05), indicating that no antibodies to neoantigens were generated. Liquid A1PI and Lyophilized A1PI have similar profiles with respect to biochemical characteristics, PK, safety and neoantigenicity.

Paraneoplastic syndromes are defined as clinical syndromes that are not related to direct tumor invasion or compression but are secondary to tumor secretion of functional peptides/hormones or related to immune cross-reactivity with normal host tissue. Paraneoplastic syndromes have a wide range of presentations and can present before the primary malignancy or tumor recurrence is diagnosed. They can mimic non-neoplastic processes, making detection, diagnosis and treatment difficult. However, they can also provide clues to the presence of an underlying malignancy. In this paper, we reviewed a range of paraneoplastic syndromes that can occur in children including: (1) neurologic (opsoclonus-myoclonus, limbic, anti-N-methyl-d-aspartate [NMDA] and anti-Ma2 encephalitis and myasthenia gravis); (2) endocrine (neuroendocrine tumors, hypercalcemia, SIADH [syndrome of inappropriate antidiuretic hormone secretion], osteomalacia/rickets and ROHHAD [rapid onset of obesity, hypoventilation, hypothalamic dysfunction and autonomic dysregulation]); and (3) dermatologic/rheumatologic syndromes (hypertrophic osteoarthropathy and paraneoplastic pemphigus). Familiarity with these syndromes can aid in early diagnosis, treatment and imaging optimization.

Rwanda is a country of 12 million people with 41% of its population under the age of 14 years. Despite major improvements in health care since the 1994 genocide, pediatric neuroimaging in Rwanda remains challenging. Prenatal and advanced imaging techniques, such as magnetic resonance imaging (MRI), are not widespread. As a result, many children with neurological diseases present unexpectedly as newborns or are in advanced stages of disease at diagnosis. The goal of this essay is to describe some unique features of the practice of pediatric neuroradiology in Rwanda in 2018.

BACKGROUND: A recent study showed a high prevalence of burnout in pediatric radiology. OBJECTIVE: The purpose of this study is to evaluate potential stressors contributing to burnout in pediatric radiology. MATERIALS AND METHODS: Society for Pediatric Radiology members received an invitation for an anonymous survey evaluating stressors contributing to burnout. Stressors evaluated included call burden, financial stress, work-life balance, health care evolution and job market changes, and radiology as a career choice. Additional questions regarding demographics were obtained. RESULTS: The response rate was 460/1,453 (32%). The prevalence of emotional exhaustion was 66% (286/435), depersonalization was 61% (265/433) and perceived lack of personal accomplishment was 15% (67/436). In a backward selective logistic regression model, work-life imbalance and call burden were the only significant factors predicting higher emotional exhaustion (P<0.001). Using a similar model, work-life imbalance, call burden and decreased rate of reimbursement were significantly associated with higher probability of depersonalization (P=0.033, 0.0002 and 0.015, respectively). Emotional exhaustion and depersonalization were significantly associated with higher odds of a radiologist's wish to work in another medical specialty (P=0.011 and 0.002, respectively). CONCLUSION: Key stressors contributing to burnout in pediatric radiology include work-life imbalance, pediatric call burden and a decreased rate of reimbursement. Burnout in pediatric radiology is a serious issue that needs to be addressed and prioritized on the individual and departmental/institutional levels and further investigated to develop effective interventions to mitigate it.
