RESUMO

BACKGROUND: Intraoperative handoffs have been implicated as a contributing factor in many perioperative adverse events. Despite conflicting data around their impact on perioperative outcomes, they remain a vulnerable point in the perioperative system with significant attention focused on improving them. This study aimed to understand the processes in place surrounding the point of information transfer in intraoperative handoffs. METHODS: We used semistructured interviews with anesthesia clinicians to understand the processes and systems surrounding intraoperative handoffs. Interview data were coded deductively using the Systems Engineering Initiative for Patient Safety model as a framework, with subthemes developed inductively. RESULTS: Clinicians do a significant amount of work before and after the point of information transfer to ensure a smooth handoff and safe patient care. Despite not having standardization of handoffs, most clinicians have a typical handoff organization and largely agree on content that should be included. However, there is variability based on clinician and patient characteristics, including clinician discipline and patient acuity. These handoffs are additionally impacted by the overall culture in the operating room, including the teamwork and hierarchies present among the surgical and anesthesia teams. Finally, the broader operating room logistics, including scheduling practices for surgical cases and anesthesia teams, impact the quality of intraoperative handoffs and the ability of clinicians to prepare for these handoffs. CONCLUSIONS: Handoffs involve processes beyond the point of information transfer and are embedded in the systems and culture of the operating rooms. These considerations are important when seeking to improve the quality of intraoperative handoffs.

RESUMO

INTRODUCTION: Compulsory rural service is one method of addressing limitations in health care access in marginalized areas of low- and middle-income countries, including Guatemala. This study aimed to explore Guatemalan medical students' experiences of compulsory rural service and the impact of rural service on their professional development. METHODS: Qualitative semi-structured interviews were conducted with 40 medical school graduates who completed compulsory rural service between 2012 and 2017. Interview transcripts were coded for dominant themes using an inductive approach. RESULTS: The majority of interviewees felt that rural service contributed to their professional development by increasing their clinical autonomy, awareness of social determinants of health, and humanistic practice. Interviewees identified limited supervision as a key challenge during the rotation. The majority found rural service rewarding. CONCLUSION: Guatemalan medical students felt that rural service contributed to their professional and personal development. Rural rotations build primary care skills and may increase awareness of health inequity among clinical trainees. Given ongoing healthcare worker shortages in Guatemala, innovative approaches to improving professional supervision and rural health mentoring are needed.

RESUMO

OBJECTIVE: To assess whether early modifiable dietary factors and obesity measures are associated with leukocyte telomere length at 3-5 years of age after controlling for the heritability of leukocyte telomere length in a prospective cohort of low-income Latina mothers and their children in San Francisco. STUDY DESIGN: We analyzed data from the Latinx, Eating and Diabetes cohort, a prospective study of 97 woman-infant dyads. We used linear regression models to evaluate associations between early dietary factors and obesity measures and child leukocyte telomere length at 3-5 years of age. Multivariable models included child age at the time of telomere collection, breastfeeding at 6 months (yes/no), obesity at 6 months, maternal education, child sex, and maternal and paternal leukocyte telomere length. RESULTS: Data for 73 of the 97 children at 3-5 years of age were analyzed. Any breastfeeding at 6 months was positively associated (ß = 0.14; P = .02) and obesity at 6 months was negatively associated (ß = -0.21; P < .001) with leukocyte telomere length in bivariate analyses. In multivariable models including parental leukocyte telomere length, obesity at 6 months was associated with a shorter leukocyte telomere length at 3-5 years of age (ß = -0.15; P = .02). Analyses of dietary factors showed high flavored milk consumption at 3 years of age was associated with shorter leukocyte telomere length after adjustment for possible confounders. CONCLUSIONS: In a low-income Latinx population, obesity at 6 months of age is negatively associated with cellular health at 3-5 years of age after controlling for genetic factors (parental leukocyte telomere length) associated with leukocyte telomere length. Early life obesity may be more deleterious for cellular health than obesity later in childhood.

RESUMO

BACKGROUND: We performed a systematic review using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines to identify the best available patient-reported outcome measure (PROM) of postpartum pain. METHODS: This review follows COSMIN guidelines. We searched four databases with no date limiters, for previously identified validated PROMs used to assess postpartum pain. PROMs evaluating more than one author-defined domain of postpartum pain were assessed. We sought studies evaluating psychometric properties. An overall rating was then assigned based upon COSMIN analysis, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the level of evidence for psychometric properties of included PROMs. These assessments were used to make recommendations and identify the best PROM to assess postpartum pain. RESULTS: We identified 19 studies using seven PROMs (involving 3511 women), which evaluated postpartum pain. All included studies evaluated ≥1 psychometric property of the included PROMs. An adequate number of pain domains was assessed by the Brief Pain Inventory (BPI), Short Form-BPI (SF-BPI), and McGill Pain Questionnaire (MPQ). The SF-BPI was the only PROM to demonstrate adequate content validity and at least a low-level of evidence for sufficient internal consistency, resulting in a Class A recommendation (the best performing instrument, recommended for use). CONCLUSION: SF-BPI is the best currently available PROM to assess postpartum pain. However, it fails to assess several important domains and only just met the criteria for a Class A recommendation. Future studies are warranted to develop, evaluate, and implement a new PROM designed to specifically assess postpartum pain.

RESUMO

Cohesion of biofilms made by Yersinia pestis and Yersinia pseudotuberculosis has been attributed solely to an extracellular polysaccharide matrix encoded by the hms genes (Hms-dependent extracellular matrix [Hms-ECM]). However, mutations in the Y. pseudotuberculosis BarA/UvrY/CsrB regulatory cascade enhance biofilm stability without dramatically increasing Hms-ECM production. We found that treatment with proteinase K enzyme effectively destabilized Y. pseudotuberculosiscsrB mutant biofilms, suggesting that cell-cell interactions might be mediated by protein adhesins or extracellular matrix proteins. We identified an uncharacterized trimeric autotransporter lipoprotein (YPTB2394), repressed by csrB, which has been referred to as YadE. Biofilms made by a ΔyadE mutant strain were extremely sensitive to mechanical disruption. Overexpression of yadE in wild-type Y. pseudotuberculosis increased biofilm cohesion, similar to biofilms made by csrB or uvrY mutants. We found that the Rcs signaling cascade, which represses Hms-ECM production, activated expression of yadE The yadE gene appears to be functional in Y. pseudotuberculosis but is a pseudogene in modern Y. pestis strains. Expression of functional yadE in Y. pestis KIM6+ weakened biofilms made by these bacteria. This suggests that although the YadE autotransporter protein increases Y. pseudotuberculosis biofilm stability, it may be incompatible with the Hms-ECM production that is essential for Y. pestis biofilm production in fleas. Inactivation of yadE in Y. pestis may be another instance of selective gene loss in the evolution of flea-borne transmission by this species.IMPORTANCE The evolution of Yersinia pestis from its Y. pseudotuberculosis ancestor involved gene acquisition and gene losses, leading to differences in biofilm production. Characterizing the unique biofilm features of both species may provide better understanding of how each adapts to its specific niches. This study identifies a trimeric autotransporter, YadE, that promotes biofilm stability of Y. pseudotuberculosis but which has been inactivated in Y. pestis, perhaps because it is not compatible with the Hms polysaccharide that is crucial for biofilms inside fleas. We also reveal that the Rcs signaling cascade, which represses Hms expression, activates YadE in Y. pseudotuberculosis The ability of Y. pseudotuberculosis to use polysaccharide or YadE protein for cell-cell adhesion may help it produce biofilms in different environments.

RESUMO

We recently reported that naltrexone blocks antidepressant effects of ketamine in humans, indicating that antidepressant effects of ketamine require opioid receptor activation. However, it is unknown if opioid receptors are also involved in ketamine's antisuicidality effects. Here, in a secondary analysis of our recent clinical trial, we test whether naltrexone attenuates antisuicidality effects of ketamine. Participants were pretreated with naltrexone or placebo prior to intravenous ketamine in a double-blinded crossover design. Suicidality was measured with the Hamilton Depression Rating Scale item 3, Montgomery-Åsberg Depression Rating Scale item 10, and Columbia Suicide Severity Rating Scale. In the 12 participants who completed naltrexone and placebo conditions, naltrexone attenuated the antisuicidality effects of ketamine on all three suicidality scales/subscales (linear mixed model, fixed pretreatment effect, p < 0.01). Results indicate that opioid receptor activation plays a significant role in the antisuicidality effects of ketamine.

RESUMO

Historically, medical trainees were educated in the hospital on real patients. Over the last decade, there has been a shift to practicing skills through simulations with mannequins or patient actors. Virtual reality (VR), and in particular, the use of 360-degree video and audio (cineVR), is the next-generation advancement in medical simulation that has novel applications to augment clinical skill practice, empathy building, and team training. In this paper, we describe methods to design and develop a cineVR medical education curriculum for trauma care training using real patient care scenarios at an urban, safety-net hospital and Level 1 trauma center. The purpose of this publication is to detail the process of finding a cineVR production partner; choosing the camera perspectives; maintaining patient, provider, and staff privacy; ensuring data security; executing the cineVR production process; and building the curriculum.

RESUMO

INTRODUCTION: Diabetes self-management education (DSME) is a fundamental element of type 2 diabetes care. Although 75% of adults with diabetes worldwide live in low-income and middle-income countries (LMICs), limited DSME research has been conducted in LMICs. The objective of this study was to evaluate a home-based DSME intervention in rural Guatemala. METHODS: We conducted a prospective study of a DSME intervention using a quasi-experimental, single-group pretest-posttest design. We enrolled 90 participants in the intervention, which consisted of 6 home visits (May 2014-July 2016) conducted by a diabetes educator using a curriculum culturally and linguistically tailored to rural Mayan populations. Primary outcomes were changes in mean hemoglobin A1c (HbA1c) and mean systolic and diastolic blood pressure at baseline and at 12 months. Secondary outcomes were diabetes knowledge and self-care activities at baseline and intervention completion. RESULTS: HbA1c decreased significantly from baseline to 12 months (absolute mean change, -1.5%; 95% confidence interval [CI], -1.9% to -1.0%; P < .001). Systolic blood pressure also improved significantly at 12 months (-6.2 mm Hg; 95% CI, -10.1 to -2.2 mm Hg; P = .002); changes in diastolic blood pressure were not significant (-1.6 mm Hg; 95% CI, -3.9 to -0.7 mm Hg; P = .17). We also found significant improvements in diabetes knowledge and self-care activities from baseline to intervention completion. CONCLUSION: DSME interventions can be successfully delivered in a setting with an underresourced health system, high poverty rate, and unique cultural characteristics like Mayan Guatemala. Our findings point to the need for more DSME research in resource-limited settings globally.

RESUMO

PURPOSE: Congenital hand differences are infrequent phenomena, and their treatment represents a relatively small fraction of cases performed by hand surgeons. Little is known about the incidence of wound complications and acute postoperative problems given the relative rarity of these procedures. This study sought to characterize the incidence of complications within 30 days of surgery for congenital hand differences. METHODS: The National Surgical Quality Improvement Program (NSQIP) contains prospective data regarding 30-day morbidity from 64 pediatric centers across the United States. Data from all available years (2012-2014) were queried for Current Procedural Terminology (CPT) codes pertinent to the treatment of congenital hand differences. Bivariate statistics, Fisher exact tests and Poisson 95% confidence intervals (95% CI) were used to assess the incidence of complications and examine risk factors for these outcomes. RESULTS: We identified a total of 1,656 congenital hand cases that represented 4 different CPT codes, including surgery for simple syndactyly, complex syndactyly, and polydactyly. The overall incidence of complications was 2.2% (95% CI, 1.6%-3.1%; n = 37) with the most common complication being superficial surgical site infection (1.7%; 95% CI, 1.1%-2.4%) followed by related readmission (0.3%; 95% CI, 0.1%-0.7%). There was a higher incidence of complications observed in patients undergoing complex syndactyly repair (5.2% for complex syndactyly repair vs 2.3% for all others). CONCLUSIONS: The rate of acute complications following procedures to correct syndactyly and polydactyly is low, the most common of which is superficial surgical site infection. The incidence of acute complications may be helpful in counseling patients and families. We suggest that further research must prioritize collecting data on long-term functional outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

RESUMO

With substance abuse being a significant problem in Oklahoma, the Oklahoma Department of Mental Health and Substance Abuse Services aimed to address these problems using the Strategic Prevention Framework to empower local communities and to assist in implementing prevention strategies based on epidemiological data by establishing the Regional Epidemiological Outcomes Workgroup (REOW) network. Seventeen REOWs across the state helped identify and use community resources to collect, analyze, and interpret epidemiological data to measure the burden of substance abuse problems and the associated intermediate variables. The REOWs prioritized the needs of each community based on the data, identified the gaps and limitations in available community-level data, and helped find solutions. The REOWs serve as a permanent resource for the communities to establish a sustainable and ongoing monitoring system. With this comprehensive network, prevention providers and coalitions have a partner to assist in strategically allocating resources to address substance abuse and other emerging public health issues. The issues identified among different public health areas can help different community sectors formulate their strategy and address key problems in their areas. The REOW network brings awareness more effectively and efficiently to communities about eminent dangers posed by different health-related problems and behaviors.

RESUMO

BACKGROUND: Doxorubicin (DOXO) is an effective anthracycline chemotherapeutic, but its use is limited by cumulative dose-dependent cardiotoxicity. Neuregulin-1ß is an ErbB receptor family ligand that is effective against DOXO-induced cardiomyopathy in experimental models but is also proneoplastic. We previously showed that an engineered bivalent neuregulin-1ß (NN) has reduced proneoplastic potential in comparison with the epidermal growth factor-like domain of neuregulin-1ß (NRG), an effect mediated by receptor biasing toward ErbB3 homotypic interactions uncommonly formed by native neuregulin-1ß. Here, we hypothesized that a newly formulated, covalent NN would be cardioprotective with reduced proneoplastic effects in comparison with NRG. METHODS AND RESULTS: NN was expressed as a maltose-binding protein fusion in Escherichia coli. As established previously, NN stimulated antineoplastic or cytostatic signaling and phenotype in cancer cells, whereas NRG stimulated proneoplastic signaling and phenotype. In neonatal rat cardiomyocytes, NN and NRG induced similar downstream signaling. NN, like NRG, attenuated the double-stranded DNA breaks associated with DOXO exposure in neonatal rat cardiomyocytes and human cardiomyocytes derived from induced pluripotent stem cells. NN treatment significantly attenuated DOXO-induced decrease in fractional shortening as measured by blinded echocardiography in mice in a chronic cardiomyopathy model (57.7±0.6% versus 50.9±2.6%, P=0.004), whereas native NRG had no significant effect (49.4±3.7% versus 50.9±2.6%, P=0.813). CONCLUSIONS: NN is a cardioprotective agent that promotes cardiomyocyte survival and improves cardiac function in DOXO-induced cardiotoxicity. Given the reduced proneoplastic potential of NN versus NRG, NN has translational potential for cardioprotection in patients with cancer receiving anthracyclines.

RESUMO

OBJECTIVES: Pediatric fluid resuscitation in sub-Saharan Africa has traditionally occurred in inpatients. The landmark Fluid Expansion as Supportive Therapy (FEAST) trial showed fluid boluses for febrile children in this inpatient setting increased mortality. As emergency care expands in sub-Saharan Africa, fluid resuscitation increasingly occurs in the emergency unit. The objective of this study was to determine the mortality impact of emergency unit fluid resuscitation on febrile pediatric patients in Uganda. METHODS: This retrospective cohort study used data from 2012-2019 from a single emergency unit in rural Western Uganda to compare three-day mortality for febrile patients that did and did not receive fluids in the emergency unit. Propensity score matching was used to create matched cohorts. Crude and multivariable logistic regression analysis (using both complete case analysis and multiple imputation) were performed on matched and unmatched cohorts. Sensitivity analysis was done separately for patients meeting FEAST inclusion and exclusion criteria. RESULTS: The analysis included 3087 febrile patients aged 2 months to 12 years with 1,526 patients receiving fluids and 1,561 not receiving fluids. The matched cohorts each had 1,180 patients. Overall mortality was 4.0%. No significant mortality benefit or harm was shown in the crude unmatched (Odds Ratio [95% Confidence Interval] = 0.88 [0.61-1.26] or crude matched (1.00 [0.66-1.50]) cohorts. Adjusted cohort analysis (including both complete case analysis and multiple imputation) and sensitivity analysis of patients meeting FEAST inclusion and exclusion criteria all also failed to show benefit or harm. Post-hoc power calculations showed the study was powered to detect the absolute harm seen in FEAST but not the relative risk increase. CONCLUSIONS: This study's primary finding is that fluid resuscitation in the emergency unit did not significantly increase or decrease three-day mortality for febrile children in Uganda. Universally aggressive or fluid-sparing emergency unit protocols are unlikely to be best practices, and choices about fluid resuscitation should be individualized.

RESUMO

BACKGROUND: Patient-reported outcome measures (PROMs) provide clinicians and consumers a platform to inform and improve healthcare planning and management. Aboriginal people experience disproportionately high rates of chronic diseases, including type 2 diabetes. Treatment and management require holistic approaches that draw on culturally relevant resources and assessment tools. This study explored perceptions of Aboriginal people about two diabetes management-related PROMs (PROMIS-29, PAID Scale). METHODS: Twenty-nine Aboriginal people living with diabetes in the Shoalhaven discussed two PROMs in one of four focus groups or at an individual interview. Preliminary data coding was conducted by clinician researchers, with thematic analysis overseen by Aboriginal co-researchers. Subsequent individual interviews with participants were undertaken to seek further feedback and articulate what is needed to improve methods of evaluating Aboriginal people's self-reported quality of life and diabetes management. RESULTS: The PROMs did not capture information or knowledge that Aboriginal people considered relevant to their diabetes-related health care. Participants' recommendations included adapting survey materials to be more culturally sensitive; for example, by improving the alignment of measures with common day-to-day activities. This study also describes a genuine collaborative, Aboriginal community-guided approach to evaluate 'fit-for-purpose' diabetes management tools. CONCLUSIONS: Appropriate evaluation methods are paramount to address the disproportionate burden of diabetes experienced by Aboriginal peoples and overcome inverse diabetes care. Our learnings will contribute to development of tools, resources or methods that capture culturally tailored outcome measures. Study findings are relevant to clinicians and researchers using and/or developing Patient Reported Measures, particularly in relation to the practicality of tools for First Nations peoples.

RESUMO

Although international guidelines exist for the prevention of surgical site infections, their implementation in diverse clinical contexts, especially in low and middle-income countries, is challenging due to the lack of available resources and organizational structure of facilities. The goal of this project was to develop a series of video training aids to highlight best practices in surgical infection prevention in hospitals with limited resources and to provide practical solutions to common challenges faced in these settings. Using the validated Clean Cut education framework for infection prevention developed by Lifebox, a charity devoted to improving surgical and anesthetic safety, we partnered with clinicians in one Ethiopian hospital to create six educational videos giving practical guidelines for infection prevention under resource variable conditions. These include: 1) proper use of the WHO Surgical Safety Checklist, 2) hand and skin antisepsis, 3) confirming instrument sterility, 4) maintaining the sterile field, 5) antibiotic prophylaxis, and 6) gauze counting. Gaps in available online educational materials were identified in each of the six areas. Videos were created providing setting-specific education and addressing gaps in existing materials for each of the infection prevention topics. These videos are now integrated into infection prevention curricula through Lifebox in Ethiopia and ongoing data collection to evaluate acceptability and efficacy is ongoing. Surgical education videos on infection prevention topics addressing location-specific resources and workarounds can be useful to hospitals operating in resource-limited settings for training staff and supporting quality and safety efforts in surgery.

RESUMO

The ErbB receptor family is dysregulated in many cancers, and its therapeutic manipulation by targeted antibodies and kinase inhibitors has resulted in effective chemotherapies. However, many malignancies remain refractory to current interventions. We describe a new approach that directs ErbB receptor interactions, resulting in biased signaling and phenotypes. Due to known receptor-ligand affinities and the necessity of ErbB receptors to dimerize to signal, bivalent ligands, formed by the synthetic linkage of two neuregulin-1ß (NRG) moieties, two epidermal growth factor (EGF) moieties, or an EGF and a NRG moiety, can potentially drive homotypic receptor interactions and diminish formation of HER2-containing heterodimers, which are implicated in many malignancies and are a prevalent outcome of stimulation by native, monovalent EGF, or NRG. We demonstrate the therapeutic potential of this approach by showing that bivalent NRG (NN) can bias signaling in HER3-expressing cancer cells, resulting in some cases in decreased migration, inhibited proliferation, and increased apoptosis, whereas native NRG stimulation increased the malignant potential of the same cells. Hence, this new approach may have therapeutic relevance in ovarian, breast, lung, and other cancers in which HER3 has been implicated.

RESUMO

Bacterial cyclic nucleotide gated (bCNG) channels are generally a nonmechanosensitive subset of the mechanosensitive channel of small conductance (MscS) superfamily. bCNG channels are composed of an MscS channel domain, a linking domain, and a cyclic nucleotide binding domain. Among bCNG channels, the channel domain of Ss-bCNGa, a bCNG channel from Synechocystis sp. PCC 6803, is most identical to Escherichia coli (Ec) MscS. This channel also exhibits limited mechanosensation in response to osmotic downshock assays, making it the only known full-length bCNG channel to respond to hypoosmotic stress. Here, we compare and contrast the ability of Ss-bCNGa to gate in response to mechanical tension with Se-bCNG, a nonmechanosensitive bCNG channel, and Ec-MscS, a prototypical mechanosensitive channel. Compared with Ec-MscS, Ss-bCNGa only exhibits limited mechanosensation, which is most likely a result of the inability of Ss-bCNGa to form the strong lipid contacts needed for significant function. Unlike Ec-MscS, Ss-bCNGa displays a mechanical response that increases with protein expression level, which may result from channel clustering driven by interchannel cation-π interactions.

RESUMO

BACKGROUND: Patient-reported outcome measures (PROMs) provide patients with a platform to report on healthcare services and interventions, including the management of diabetes and other chronic diseases. Given the major disparity in incidence and prevalence of diabetes between Aboriginal and non-Aboriginal people, it is crucial that PROMs meet the cultural, spiritual and medical needs of this high-risk population. Anecdotal evidence indicates that PROMs do not capture accurate information about the healthcare of Aboriginal people with Type 2 diabetes. Therefore, the aim of this study is to explore the perceptions of Aboriginal people in regional New South Wales (NSW), Australia, about the cultural appropriateness of a set of PROMs relating to diabetes management. METHODS/DESIGN: Up to 50 Aboriginal people aged 18 years or older with type 1 or type 2 diabetes living in the Shoalhaven region in NSW, will be recruited. Eligible, consenting participants will attend a focus group or individual interview where they will review the PROM tools (PROMIS 29 and PAID scale) currently used for diabetes management. Semi-structured questions will be used to gather information about PROMs and discussions will be recorded for analysis. Research team members will yarn about the data with Aboriginal co-researchers and community stakeholders to apply an Indigenous lens to coding and thematic analysis. CONCLUSION: This study will explore the cultural appropriateness of government-initiated evaluation of health outcomes, and make recommendations about how these evaluations can be better suited to Aboriginal people. The lessons from this study will be of interest to those conducting research or quality assessment activities related to PROMs, and those involved with Aboriginal-focused research and project implementation.

RESUMO

Adhesive taping is commonly used to reinforce wound closure and approximate minor lacerations. Recently, tissue adhesives such as 2-octylcyanoacrylate have gained popularity because of their high tensile strength, bacteriostatic properties, and spontaneous peeling. We sought to evaluate the cosmetic result of upper extremity incisions closed primarily by subcuticular suture, randomizing the application of tissue adhesive vs adhesive taping to different halves of the same surgical incision. Subjects were recruited from patients undergoing common procedures at the senior surgeon's hand surgery clinic. After primary closure, we applied either quarter-inch adhesive tape or tissue adhesive to the proximal and distal aspects of the wounds, based on a preoperative randomization protocol. We assessed the scars at approximately 3 months (range, 2-5 months). Subjects completed a validated scar assessment questionnaire, and a blinded photograph was obtained to allow 2 independent surgeons to assess the scar. Mean age was 63 years (SD, 11.8 years; range, 21-88 years); 56% of patients were women, and 44% were men. Most of the incisions were open carpal tunnel release and thumb carpometacarpal arthroplasty (14 each). Adhesive taping showed a better overall mean score based on evaluation by the hand surgeons, a finding that was statistically significant. The greatest differences were observed between color and size, but no subcategories were significantly different. Patients reported nonstatistical, but slightly better overall cosmetic outcomes with adhesive taping rather than tissue adhesive. Adhesive strips provide a modest but significant improvement in cosmetic outcomes vs more expensive tissue adhesive. Future evaluation of closure methods that evaluate cost, speed of application, suture technique, and dressing will optimize scar appearance. [Orthopedics. 2022;45(1):e42-e46.].
