Informing a Canadian Skin Science Trainee Program Based on the State of Trainee Programs Offered by International Academic Societies.

BACKGROUND: For dermatology to effectively address the ever-growing medical needs, longstanding communication barriers across investigators working in different research pillars and practicing clinicians must be improved. To address this problem, trainee-specific programs are now evolving to align their educational landscape across basic science, translational and clinical research programs. OBJECTIVES: To establish a Skin Investigation Network of Canada (SkIN Canada) training roadmap for the career and skill development of future clinicians, clinican scientists and basic scientists in Canada. This Working Group aims to strengthen and harmonize collaborations and capacity across the skin research community. METHODS: The Working Group conducted a search of established international academic societies which offered trainee programs with mandates similar to SkIN Canada. Societies' program items and meetings were evaluated by use of an interview survey and/or the collection of publicly available data. Program logistics, objectives and feedback were assessed for commonalities and factors reported or determined to improve trainee experience. RESULTS: Through the various factors explored, the Working Group discovered the need for increasing program accessibility, creating opportunities for soft skill development, emphasizing the importance of current challenges, collecting and responding to feedback, and improving knowledge sharing to bridge pillars of skin research. CONCLUSIONS: Although improvements have been made to trainee education in recent years, a plurality of approaches exist and many of the underlying roadblocks remain unresolved. To establish fundamental clinician-basic scientist collaboration and training efforts, this Working Group highlights important factors to include and consider in building a trainee program and emphasizes the importance of trainee education.

MED27 Variants Cause Developmental Delay, Dystonia, and Cerebellar Hypoplasia.

The Mediator multiprotein complex functions as a regulator of RNA polymerase II-catalyzed gene transcription. In this study, exome sequencing detected biallelic putative disease-causing variants in MED27, encoding Mediator complex subunit 27, in 16 patients from 11 families with a novel neurodevelopmental syndrome. Patient phenotypes are highly homogeneous, including global developmental delay, intellectual disability, axial hypotonia with distal spasticity, dystonic movements, and cerebellar hypoplasia. Seizures and cataracts were noted in severely affected individuals. Identification of multiple patients with biallelic MED27 variants supports the critical role of MED27 in normal human neural development, particularly for the cerebellum. ANN NEUROL 2021;89:828-833.

Cook Like A Boss: An effective co-created multidisciplinary approach to improving children's cooking competence.

Cooking interventions are emphasised as promising methods for changing children's food-related preferences, attitudes and behaviours. However, criticisms remain, including relatively weak intervention designs; lack of validated tools, and limited underpinning theory. Therefore, this research aimed to assess the effectiveness of a theory-driven co-created children's cooking intervention with underpinning rationale for the content, using a validated measure. 'Cook Like A Boss' was a one week, controlled cooking camp style intervention. Thirty two children aged 10-12 years participated. The intervention was developed using the Cook-Ed model for planning, implementing and evaluating cooking programs and was underpinned by Social Learning theory and Experiential Learning theory. The intervention content was developed in a co-creation process with the research team, a chef and the children. The underlying developmental skills required for the recipes were assessed to ensure they were age-appropriate. Children completed pre and post measurements including perceived cooking competence. Process evaluations were also gathered. There was a significant increase in perceived cooking competence after the intervention (P < 0.05) and a significant difference between the intervention and control group (P < 0.001). Additionally, process evaluations found the intervention to have high fidelity and dose received and that it was received extremely positively. The 'Cook Like A Boss' children's cooking camp was an effective multidisciplinary co-created intervention with a vulnerable group, e.g. children, guided by a model and underpinned by theory. The content was developed to ensure it was age-appropriate and achievable for the children. This approach could act as a template for future children's cooking interventions.

Sexual knowledge and behaviour in 22q11.2 deletion syndrome, a complex care condition.

BACKGROUND: There is limited information about sexual knowledge and behaviours in adults with complex care needs, including those with 22q11.2 deletion syndrome (22q) which represents a group predisposed to intellectual disabilities. METHODS: We conducted sexual health assessments with 67 adults with 22q, examining whether those with knowledge deficits and a history of engaging in sexual activities with others would be more likely to engage in high-risk behaviours. RESULTS: The majority (65.7%) of adults with 22q were sexually active with others; most (70.1%) had sexual knowledge deficits. Those with intellectual disabilities were more likely (p = .0012) to have deficits in certain topics. In the sexually active subgroup, most (81.8%) engaged in high-risk sexual behaviours, regardless of intellectual disability or knowledge deficits. CONCLUSION: The results suggest a need for increased dialogue, repeated education, genetic counselling and preventive healthcare measures related to sexuality in 22q and potentially in other complex care conditions.

Early recurrence after pulmonary vein isolation is associated with inferior long-term outcomes: Insights from a retrospective cohort study.

AIMS: The aim of this retrospective cohort study was to assess the influence of early recurrence (ER) after pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF) on long-term outcomes and to identify clinical variables associated with ER. METHODS: We retrospectively collected clinical and procedural data from 1285 patients with paroxysmal AF who underwent PVI from 2011 to 2016. Kaplan-Meier, receiver operating characteristic (ROC) curve, logistic and Cox regression analyses were performed to analyze the influence of ER on long-term outcomes. RESULTS: ER was observed in 13% of patients. Kaplan-Meier analyses showed significantly different outcomes in 1285 patients with and without ER (49% vs 74%, log rank P < .01) and in 286 patients in the subgroup that underwent reablation (44% vs 79%, log rank P < .01). The hazard ratio (HR) of ER was 1.7 within 48 hours (5% of patients), 2.7 within 1 month (5%), 3.0 within 2 months (2%), and 6.4 within 3 months (1%) for late recurrence (LR), P < .01. ROC analysis (area under the curve [AUC] = 0.79) resulted in 70.3% sensitivity and 74.2% specificity for a 14-day blanking period, and 53.1% sensitivity and 85.5% specificity for a 30-day blanking period. Female patients (odds ratio [OR] 1.69, P < .01) and those with diabetes (OR 1.95, P = .01) were at higher risk for ER. CONCLUSIONS: ER is observed in a substantial number of patients with paroxysmal AF after PVI and has a continuous direct effect on LR according to the timing of ER. Randomized trials are required to assess the safety and effects of reablations in a shortened blanking period on long-term outcomes.

Application of protection motivation theory to clinical trial enrolment for pediatric chronic conditions.

BACKGROUND: Parents of children living with chronic but manageable conditions hope for improved therapies or cures, including Advanced Therapy Medicinal Products (ATMPs). Multiple pediatric clinical trials for ATMPs are underway, but the risk profile of ATMPs for chronic conditions is largely unknown and likely different than for terminal pediatric illnesses. Applying Protection Motivation Theory modified to the context of pediatric ATMP clinical trial enrollment, our study analyses information needs of parents of children living with chronic manageable conditions: Type 1 Diabetes (T1D) or Inherited Retinal Diseases (IRD). METHODS: We conducted semi-structured interviews with 15 parents of children living with T1D and 14 parents of children living with an IRD about: a) family background and the diagnostic experience; b) awareness of gene and stem cell therapy research and clinical trials for T1D and IRD; c) information sources on trials and responses to that information; d) attitudes to trial participation, including internationally; e) understanding of trial purpose and process; and f) any experiences with trial participation. We then discussed a pediatric ATMP clinical trial information sheet, which we developed with experts. We applied directed qualitative content analysis, based on PMT, to examine the information preferences of parents in deciding whether to enrol their children in stem cell or gene therapy clinical trials. RESULTS: Parents balanced trial risks against their child's ability to cope with the chronic condition. The better the child's ability to cope with vision impairment or insulin management, the less likely parents were to assume trial risks. Conversely, if the child struggled with his/her vision loss, parents were more likely to be interested in trial participation, but only if the risks were low and likelihood for potential benefit was high. CONCLUSIONS: Fear of adverse events as part of threat appraisal was the predominant consideration for parents in considering whether to enroll their child living with a manageable, chronic condition in a pediatric clinical trial of an ATMP. This consideration outweighed potential benefits and severity of their child's condition. Parents called for available safety data and fulsome communication processes that would enable them to make informed decisions about clinical trial enrolment on behalf of their children.

Recurrent De Novo and Biallelic Variation of ATAD3A, Encoding a Mitochondrial Membrane Protein, Results in Distinct Neurological Syndromes.

ATPase family AAA-domain containing protein 3A (ATAD3A) is a nuclear-encoded mitochondrial membrane protein implicated in mitochondrial dynamics, nucleoid organization, protein translation, cell growth, and cholesterol metabolism. We identified a recurrent de novo ATAD3A c.1582C>T (p.Arg528Trp) variant by whole-exome sequencing (WES) in five unrelated individuals with a core phenotype of global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy. We also describe two families with biallelic variants in ATAD3A, including a homozygous variant in two siblings, and biallelic ATAD3A deletions mediated by nonallelic homologous recombination (NAHR) between ATAD3A and gene family members ATAD3B and ATAD3C. Tissue-specific overexpression of borR534W, the Drosophila mutation homologous to the human c.1582C>T (p.Arg528Trp) variant, resulted in a dramatic decrease in mitochondrial content, aberrant mitochondrial morphology, and increased autophagy. Homozygous null bor larvae showed a significant decrease of mitochondria, while overexpression of borWT resulted in larger, elongated mitochondria. Finally, fibroblasts of an affected individual exhibited increased mitophagy. We conclude that the p.Arg528Trp variant functions through a dominant-negative mechanism that results in small mitochondria that trigger mitophagy, resulting in a reduction in mitochondrial content. ATAD3A variation represents an additional link between mitochondrial dynamics and recognizable neurological syndromes, as seen with MFN2, OPA1, DNM1L, and STAT2 mutations.

Programme theory development and formative evaluation of a provincial knowledge translation unit.

BACKGROUND: Research shows a significant gap between healthcare research and evidence-based healthcare policy and practice. Knowledge translation (KT) has an important role in addressing this gap by bolstering evidence-informed healthcare. Canada's Strategy for Patient-Oriented Research (SPOR) is a nationally mandated and supported initiative developed to respond to the gap between research and practice. One aspect of SPOR is the provincial/territorial SUpport for People and Patient-Oriented Research and Trials (SUPPORT) Units, intended to assist local health researchers and systems to reach the goal of improving the quality and quantity of patient-oriented research in Canada. This article presents the programme theory development and a formative evaluation of the KT Platform in Alberta's SPOR SUPPORT Unit. METHODS: We used a mixed-methods approach to develop the KT Platform's programme theory and subsequently conducted the formative evaluation. An extensive needs assessment, comprised of 59 qualitative interviews with researchers and health systems employees in Canada with an interest in KT, served as the basis for our programme theory design. Three years after launching the KT Platform, we hired an evaluation consultant to conduct a formative evaluation of the Platform's programme theory and operations. The evaluation was performed by conducting nine interviews with KT Platform service users (n = 6) and KT experts acting in advisory capacities to the KT Platform (n = 3). RESULTS: The KT Platform developed a '4C Model' as a summary of the Platform's programme theory. This model is designed to meet local needs for capacity-building, a community of practice, consultation services, and contributions to KT science. This suite of services was found to help the local health system implement health evidence with measurable positive health outcomes. However, the community remains hesitant about their capacity as individuals to design and perform important KT activities independently. CONCLUSIONS: With the mandate and support provided by SPOR, the KT Platform was able to design a strong programme theory based on evidence from an extensive needs assessment of the local community. The resulting 4C Model has provided a framework for KT work to assist in improving local health outcomes and can be considered by others designing KT programmes as a useful model to follow. Ongoing monitoring and assessment are required to continue to identify and respond to local needs.

Insights into ablation of persistent atrial fibrillation: Lessons from 6-year clinical outcomes.

INTRODUCTION: Ablation of persistent atrial fibrillation (AF) is a potential treatment option for symptomatic patients. We sought to evaluate the critical role of circumferential pulmonary vein isolation (CPVI) in the ablation of persistent AF. METHODS AND RESULTS: A total of 341 ablation procedures were performed in 174 consecutive patients with persistent AF. CPVI was performed in all patients, additional ablation was only performed if electrical cardioversion failed after CPVI. During a median follow-up (FU) of 89 (63; 89) months, stable sinus rhythm was documented in 42/170 (25%) patients after a single procedure and in 111/164 (68%) patients after 1.9 ± 1.1 procedures. Stable SR was achieved in 40/75 (53%) patients in whom only CPVI was performed during the index and repeat procedures and in 71/89 (79%) patients with CPVI plus additional ablation. The main predictor for ablation success was duration of persistent AF before the index procedure (P < 0.001, HR ± CI: 1.608 [1.034, 1.103]). Responders to CPVI during the initial procedure had a significantly better multiple-procedure outcome after 42 months of FU compared to CPVI nonresponders (P  =  0.0365). Conversion during the index procedure had no impact on clinical outcomes (P  =  0.0903). Persistent AF regressed to paroxysmal AF in 16% of patients. CONCLUSIONS: We demonstrate a 25% single- and 68% multiple-procedure success in patients with persistent AF, while stable SR was achieved in 53% of patients with pure CPVI during all procedures and in 79% of patients with CPVI plus additional ablation. Only duration of persistent AF before ablation had a statistically significant impact on ablation outcome.

EP radiofrequency generators: Significant offsets between selected and delivered power?

INTRODUCTION: For radiofrequency (RF) ablation, the EP Shuttle® (Stockert GmbH, Freiburg, Germany), Ampere® (St. Jude Medical, St. Paul, MN, USA), and SmartAblate® (Biosense Webster, Diamond Bar, CA, USA) generator models are most frequently used in clinical practice. The aim of this study was to assess the correlation between selected and delivered RF power for different generators. METHODS AND RESULTS: In an experimental setup, ablation catheters were connected to the EP Shuttle® , Ampere® , and SmartAblate® generators. The power delivered by the generators was measured using a current converter and an oscilloscope. The selected power displayed on the generator was compared to the actually delivered power measured by the experimental setup (n = 800 measurements). The offsets between selected and delivered power increased significantly with impedance (EP Shuttle® ). For example, at a selected power of 30 W, the delivered power was 40.3 W (EP Shuttle® ), 30.1 W (Ampere® ), and 28.1 W (SmartAblate® ) at an impedance of 200 Ω. In addition, ablation lesions (n = 80) were created in ex vivo porcine cardiac muscle preparations. The resulting ablation lesion size was calculated in caliper measurements. When the EP Shuttle® generator was operated at 200 Ω, the resulting lesion size was significantly larger than at 100 Ω. There were no significant offsets between power delivery and lesion size when using the Ampere® or SmartAblate® generators. CONCLUSIONS: The Ampere® and SmartAblate® generator models deliver accurate power as selected by the user. The power delivered by the EP Shuttle® generator exceeds the selected power by up to 40% depending on impedance. The findings were confirmed in ex vivo porcine heart experiments and should be considered in clinical practice.

Catheter ablation of left atrial arrhythmias on uninterrupted oral anticoagulation with vitamin K antagonists: What is the relationship between international normalized ratio, activated clotting time, and procedure-related complications?

BACKGROUND: Ablation of atrial fibrillation (AF) on uninterrupted phenprocoumon reduces periprocedural thromboembolic and bleeding complications. Heparin is administered intraprocedurally to achieve activated clotting times (ACT) of 300-400 seconds. We investigated the effect of international normalized ratio (INR) on ACT and intraprocedural heparin requirements. Moreover, safety of a target ACT of 250-300 seconds was investigated. METHODS AND RESULTS: We studied 949 patients referred for AF or left atrial tachycardia ablation. Patients were divided into Group 1 (n = 249) with an INR <2 and Group 2 (n = 700) with an INR ≥2. Mean INR was 1.7 ± 0.13 in Group 1 and 2.3 ± 0.25 in Group 2. Baseline, mean, minimum and maximum ACT were significantly lower in Group 1 (138 ± 17 seconds vs. 145 ± 21 seconds; 281 ± 28 seconds vs. 288 ± 29 seconds; 251 ± 36 seconds vs. 258 ± 34 seconds; 307 ± 32 seconds vs. 316 ± 40 seconds; P <0.05). Intraprocedural heparin requirements adjusted to body weight were lower in Group 1 (127 ± 41 U/kg vs. 122 ± 40 U/kg). Weak correlations between INR and baseline, mean, minimum and maximum ACT as well as intraprocedural heparin requirements were observed. No differences regarding major or minor complications were found. INR and periprocedural anticoagulation parameters had no influence on major complications. No thromboembolic complications were observed in both groups with a target ACT value of 250-300 seconds. CONCLUSIONS: There is only a weak correlation between INR, intraprocedural ACT, and intraprocedural heparin requirements. Periprocedural target ACT of 250-300 seconds seems safe and does not increase periprocedural bleeding and thromboembolic complications in patients undergoing RF ablation on uninterrupted phenprocoumon therapy.

"Shock and Go?" extracorporeal cardio-pulmonary resuscitation in the golden-hour of ROSC.

OBJECTIVES: The feasibility and outcomes of 35 consecutive patients subjected to eCPR in the tertiary cardiology center were investigated. BACKGROUND: While conventional cardiopulmonary-resuscitation (cCPR) often times achieves only mediocre outcomes extracorporeal cardiopulmonary-resuscitation (eCPR) increasingly shifts into the focus of interest. However, the scientific evidence for eCPR is sparse, particularly in the cardiological setting. METHODS: Retrospective chart analysis of 35 patients treated with eCPR between 01/2014 and 10/2015. RESULTS: The duration of cCPR until initiation of eCPR was 73.8 ± 37.6 min and resulted in an initial pH of 6.9 ± 0.2 and serum lactate level of 14.5 ± 4.8 mmol/L. About 62% (n = 22) of the patients suffered from out of hospital cardiac arrest (OHCA), 85% (n = 30) of the overall events were witnessed and bystander-CPR performed in 77% (n = 27) of cases. Cause of arrest was dominated by acute myocardial infarction (AMI, 71%), initial rhythm to a lesser degree by ventricular fibrillation/tachycardia (VF/VT, 57%). Almost all patients (n = 33, 94%) experienced return of spontaneous circulation (ROSC) after establishing extracorporeal life support (ECLS). In all 57% patients were successfully weaned from ECLS. Survival to discharge was 31% with predominantly good cerebral performance category (CPC 1-2). Survivors were more likely to receive bystander-CPR (P = 0.03) and the duration of cCPR until initiation of eCPR was significantly shorter (P = 0.004). CONCLUSIONS: Our data proves the exceptional level of efficiency of eCPR particularly when Bystander-CPR has been initiated and there is a short duration of cCPR. © 2016 Wiley Periodicals, Inc.

Partnership-building considerations for implementation science in learning health systems: a case study of the Implementation Science Collaborative in Alberta, Canada.

Introduction: Implementation of health innovations is inherently collaborative, requiring trans-sectoral partnerships between implementation researchers, innovation teams, and implementation practitioners. Implementation science has been shown to improve implementation successes; however, challenges that hinder partnerships to advance implementation science continue to persist. Using a whole-system approach to assess and respond to implementation science partnership barriers may shed light on effective responses. Methods: We conducted a case study of Alberta's learning health system, using semi-structured group and individual interviews to create a nuanced understanding of the considerations required for implementation research collaborations. We interviewed 53 participants representing 21 offices in the health system, academia, professional associations, and government who regularly plan, evaluate, and/or study health system implementation initiatives in Alberta. Using the Partnership Model for Research Capacity Building, we identified current facilitators and challenges for partnerships for conducting and using implementation science, at different levels of Alberta's health-research ecosystem. Results: Alberta's healthcare system is well set up to readily embed intervention effectiveness and efficacy research. Infrastructure was also in place to strengthen implementation practice. However, weaknesses around exchanging knowledge and skills, providing feedback and mentoring, and accommodating diversity affected the ability of both individuals and teams to build implementation science capacity. Without this capacity, teams could not participate in embedded implementation research collaborations. We report the response of the Alberta Strategy for Patient-Oriented Research SUPPORT Unit to these barriers to provide practical guidance on various program options to strengthen individual- and organization-level implementation science capacity. Discussion: This study applied a whole-system approach to assess factors across Alberta's health-research ecosystem, which affect partnerships to advance implementation science. Our findings illustrated that partnership considerations go beyond interpersonal factors and include system-wide considerations. With the results, health organization leaders have (1) a method for assessing organizational capability to readily embed implementation research and (2) a catalog of potential responses to create conditions to readily engage with implementation science in their day-to-day implementation processes.

How to use communities of practice to support change in learning health systems: A landscape of roles and guidance for management.

Background: Communities of practice support evidence-based practice and can be, in and of themselves, applied learning spaces in organizations. However, the variety of ways that communities of practice can support learning health systems are poorly characterized. Furthermore, health system leaders have little guidance on designing and resourcing communities of practice to effectively serve learning health systems. Methods: We conducted a collective case study, examining a cross-section of Canadian-based communities of practice dedicated to supporting evidence-based practice. We held semi-structured interviews with 21 participants representing 16 communities of practice and 5 community of practice facilitation platforms that provide administration support, tools, and oversight for multiple communities of practice. Using the Conceptual Framework for Value-Creating Learning Health Systems, we characterized the numerous roles that communities of practice can take to support learning health systems. We also pulled insights from the interviews on properly resourcing and managing communities of practice. Results: Communities of practice can advance learning health systems across learning cycles (ie, identifying learning priorities, generating data and knowledge, and implementing and evaluating change). They also act as important infrastructure required to share and coordinate across learning health systems. Community of practice facilitation platforms reduce staff members' workload, in turn, creating greater efficiency and effectiveness across community of practice lifespans. Furthermore, these platforms can be a mechanism to coordinate critical activities (e.g., priority alignment, knowledge brokerage/sharing across the broader system). Conclusion: To the authors' knowledge, this is the first study to characterize communities of practice across the learning health system landscape. With these results, learning health system leaders have a catalog that clarifies the potential communities of practice roles in knowledge generation, implementation, and uptake of new evidence. Furthermore, the results provide evidence that organizational investment in overarching community of practice facilitation platforms will strengthen and accelerate community of practice supports in learning health systems.

The influence of health service interactions and local policies on vaccination decision-making in immigrant women: A multi-site Canadian qualitative study.

OBJECTIVES: Research on immigrant and refugee vaccination uptake in Canada shows that immunization decisions vary by vaccine type, location, age and migration status. Despite their diversity, these studies often treat immigrant and refugee populations as a single group relative to other Canadians. In this comparative study, we explored how previous risk communication and immunization experiences influence immunization decisions by immigrant and refugee women from three communities across Canada. METHODS: Participants included women from the Punjabi immigrant community located in Surrey and Abbotsford, British Columbia (n = 36), the Nigerian immigrant community located in Winnipeg, Manitoba (n = 43), and the Congolese refugee community in Edmonton, Alberta (n = 18). Using focus groups guided by focused ethnography methodology, we sought to understand immunization experiences in Canada and before arrival, and what information sources influenced the immunization decision-making process by the women in the three communities. RESULTS: Participants had differing past experiences in Canada and before their arrival that influenced how they used information in their vaccination decisions. Clear vaccination communications and dialogue with Canadian health care providers increased trust in Canadian health care and the likelihood of vaccine uptake. By contrast, weak vaccine recommendations and antivaccination information in the community prompted participants to decline future vaccines. CONCLUSION: Given our participants' different communication preferences and needs, we argue that a one-size-fits-all communication approach is inappropriate for immigrant and refugee populations. Instead, multi-pronged communication strategies are required to reach participants and respond to previous experiences and information that may lead to vaccination hesitancy.

Postburn breast reconstruction: a scoping review.

Introduction: Postburn breast deformities pose functional and aesthetic concerns for burn patients, particularly when injury occurs before puberty, as normal breast development may be hindered. Postburn breast reconstruction aims at restoration of native anatomic features, as well as re-establishment of symmetry. The objectives of this scoping review are to map the literature on scar management and breast reconstruction, highlighting strategies that are particular to postburn deformities, as well as to establish optimal timing principles. Methods: A comprehensive search of the English literature across MEDLINE and EMBASE databases, including the grey literature, was conducted. Literature of all study designs were eligible, provided it discussed the treatment of postburn breast deformities. Results: A total of 64 studies were included. The most common study design was case series (58%) followed by retrospective cohorts (28%). Scar contracture release with split thickness skin grafts (26%) and various techniques for nipple-areola reconstruction (22%) were the most common reconstructive procedures. Discussion: Scar contracture releases predominate when there is normal breast development under a contracted skin envelope, and should be performed as soon as breast mound development is restricted. Surgical techniques widely used for postmastectomy reconstruction are required for patients with amastia or hypoplastic breasts. Conclusion: Given the heterogeneity of defects, availability of donor sites, and patient preference, no standardized guideline is available. Surgeons should combine basic scar management principles with postmastectomy techniques, adapting the surgical approach to features that are particular to thermally injured patients, as well as taking into account ideal timing considerations. Lay Summary: Breast deformities secondary to burn scars pose functional and aesthetic concerns for burn patients, particularly when injury occurs before puberty, as normal breast development may be hindered. Postburn breast reconstruction aims at restoration of native anatomic features, as well as re-establishment of symmetry. This literature review aimed at summarizing the available techniques to treat postburn breast deformities, as well as establishing optimal timing guidelines, given these issues may occur at any phase of breast development. When there is breast development under a scarred skin envelope, treatment entails scar contracture release and should be recommended as soon as the diagnosis is established, in order to allow the breast to further develop in an unrestricted manner. When there is absence of breast tissue, surgical techniques widely utilized for breast cancer reconstruction are warranted, and should be delayed until no further breast development is expected. Given the heterogeneity of deformities, availability of donor sites, and patience preference, no standardized guideline is available. Treatment options include several surgical techniques, in addition to non-surgical scar management, and timing considerations must take into account the patient's developmental phase and psychosocial wellness.

Extrapulmonary COVID-19 Presents As Spontaneous Small Bowel Perforation.

SARS-CoV2 is a well-recognized pathogen with a myriad of presenting symptoms. Well-documented pulmonary, neurological, gastrointestinal, and hematologic complications have occurred during the global COVID-19 pandemic. While gastrointestinal symptoms are the most commonly reported extrapulmonary symptom of COVID-19, the incidence of primary perforation has not been widely reported. In this case report, we describe a spontaneous small bowel perforation in a patient who was incidentally found to be COVID-19 positive. This peculiar case underlies the continued evolution of SARS-CoV2 understanding and potential unknown complications of the virus.

Containment of a Verona Integron-Encoded Metallo-Beta-Lactamase-Producing Pseudomonas aeruginosa Outbreak Associated With an Acute Care Hospital Sink-Tennessee, 2018-2020.

Background: Contaminated healthcare facility wastewater plumbing is recognized as a source of carbapenemase-producing organism transmission. In August 2019, the Tennessee Department of Health (TDH) identified a patient colonized with Verona integron-encoded metallo-beta-lactamase-producing carbapenem-resistant Pseudomonas aeruginosa (VIM-CRPA). A record review revealed that 33% (4 of 12) of all reported patients in Tennessee with VIM had history of prior admission to acute care hospital (ACH) A intensive care unit (ICU) Room X, prompting further investigation. Methods: A case was defined as polymerase chain reaction detection of blaVIM in a patient with prior admission to ACH A from November 2017 to November 2020. The TDH performed point prevalence surveys, discharge screening, onsite observations, and environmental testing at ACH A. The VIM-CRPA isolates underwent whole-genome sequencing (WGS). Results: In a screening of 44% (n = 11) of 25 patients admitted to Room X between January and June 2020, we identified 36% (n = 4) colonized with VIM-CRPA, resulting in 8 cases associated with Room X from March 2018 to June 2020. No additional cases were identified in 2 point-prevalence surveys of the ACH A ICU. Samples from the bathroom and handwashing sink drains in Room X grew VIM-CRPA; all available case and environmental isolates were found to be ST253 harboring blaVIM-1 and to be closely related by WGS. Transmission ended after implementation of intensive water management and infection control interventions. Conclusions: A single ICU room's contaminated drains were associated with 8 VIM-CRPA cases over a 2-year period. This outbreak highlights the need to include wastewater plumbing in hospital water management plans to mitigate the risk of transmission of antibiotic-resistant organisms to patients.
