Abstract
Importance Inconsistent reporting of outcomes in clinical trials of rosacea is impeding and likely preventing accurate data pooling and meta-analyses. There is a need for standardization of outcomes assessed during intervention trials of rosacea. Objective To develop a rosacea core outcome set (COS) based on key domains that are globally relevant and applicable to all demographic groups to be used as a minimum list of outcomes for reporting by rosacea clinical trials, and when appropriate, in clinical practice. Evidence Review A systematic literature review of rosacea clinical trials was conducted. Discrete outcomes were extracted and augmented through discussions and focus groups with key stakeholders. The initial list of 192 outcomes was refined to identify 50 unique outcomes that were rated through the Delphi process Round 1 by 88 panelists (63 physicians from 17 countries and 25 patients with rosacea in the US) on 9-point Likert scale. Based on feedback, an additional 11 outcomes were added in Round 2. Outcomes deemed to be critical for inclusion (rated 7-9 by ≥70% of both groups) were discussed in consensus meetings. The outcomes deemed to be most important for inclusion by at least 85% of the participants were incorporated into the final core domain set. Findings The Delphi process and consensus-building meetings identified a final core set of 8 domains for rosacea clinical trials: ocular signs and symptoms; skin signs of disease; skin symptoms; overall severity; patient satisfaction; quality of life; degree of improvement; and presence and severity of treatment-related adverse events. Recommendations were also made for application in the clinical setting. Conclusions and Relevance This core domain set for rosacea research is now available; its adoption by researchers may improve the usefulness of future trials of rosacea therapies by enabling meta-analyses and other comparisons across studies. This core domain set may also be useful in clinical practice.

Abstract
Exaggerated healing and remodeling after skin injury may cause hypertrophic and keloidal scars, which are associated with functional and quality of life impairment. There is limited guidance available regarding the relative effectiveness of therapies for hypertrophic scars and keloids. In this review, we aim to compare the effectiveness of treatments for hypertrophic scars and keloids. MEDLINE, Embase, Scopus, and the Cochrane Collaboration database were searched from inception to March 2019 for randomized control trials of treatments for hypertrophic and keloid scars that included 20 or more patients. Outcomes evaluated included the standardized mean reduction in scarring and adverse events. The type of scar and the demographic features were analyzed for their effect on clinical outcome. Based on 25 included clinical trials, intralesional injection (64.1% [95% CI 60.8-67.5%]) may be more effective than physical (29.9% [95% CI 28.9-30.9%]) or topical treatments (34% [95% CI 31.8-36.8%]). Combination of 5-fluorouracil and triamcinolone (9:1 dilution) appeared superior among intralesional treatments for keloids. Ablative laser and pulsed-dye laser were the most useful laser treatments. Regression modeling showed laser treatment response was linked to Fitzpatrick skin type (p = 0.002). Adverse events were uncommon for all treatments and mostly transient. Intralesional treatments for keloid and hypertrophic scars may be the most reliable treatment option to improve pathologic scars, while laser treatment may have specific benefits for Fitzpatrick skin types I-III over types IV-VI. Management of pathological scars is an area of critical need, where appropriate treatment can have a significant impact on quality of life.

Abstract
Cosmetic dermatology is a key subspecialty of academic dermatology. As such, academic centers are expected to demonstrate excellence in the teaching of cosmetic dermatology skills to trainees, the clinical delivery of cosmetic dermatology services to patients, and the performance of clinical research that advances knowledge and uncovers new therapies in cosmetic dermatology. The Association of Academic Cosmetic Dermatology (AACD), a newly formed medical professional society, includes as its principal aims the support of all of these areas. AACD is comprised of group of board-certified dermatologists who teach cosmetic and laser dermatology at US dermatology residency programs. An expert panel constituted by the AACD recently convened a workshop to review gaps pertaining to academic cosmetic dermatology. This panel considered needs and potential corrective initiatives in three domains: resident education, patient experience, and clinical research. The work of the panel was used to develop a roadmap, which was adopted by consensus, and which will serve to guide the AACD moving forward.

Abstract
OBJECTIVES Clinical practice guidelines (CPGs) are often created through collaboration among organizations. The use of inconsistent terminology may cause poor communication and delays. This study aimed to develop a glossary of terms related to collaboration in guideline development. STUDY DESIGN AND SETTING A literature review of collaborative guidelines was performed to develop an initial list of terms related to guideline collaboration. The list of terms was presented to the members of the Guideline International Network Guidelines Collaboration Working Group, who provided presumptive definitions for each term and proposed additional terms to be included. The revised list was subsequently reviewed by an international, multidisciplinary panel of expert stakeholders. Recommendations received during this pre-Delphi review were implemented to augment an initial draft glossary. The glossary was then critically evaluated and refined through two rounds of Delphi surveys and a virtual consensus meeting with all panel members as Delphi participants. RESULTS Forty-nine experts participated in the pre-Delphi survey, and 44 participated in the two-round Delphi process. Consensus was reached for 37 terms and definitions. CONCLUSION Uptake and utilization of this guideline collaboration glossary by key organizations and stakeholder groups may facilitate collaboration among guideline-producing organizations by improving communication, minimizing conflicts, and increasing guideline development efficiency.

Abstract
Primary cutaneous angiosarcoma (cAS) of the head and neck is a rare sarcoma with a poor prognosis and limited treatment options. We conducted a systematic review of treatments used for head and neck cAS and determined the treatment modalities that offer the longest mean overall survival (OS). Forty publications totaling 1295 patients were included. Both surgical and nonsurgical modalities have shown potential efficacy in the treatment of cAS; however, limited data preclude definitive recommendations. Multidisciplinary management of cAS should be considered to tailor treatment on a case-by-case basis.

Abstract
BACKGROUND There is considerable variation in the literature regarding the dermatopathologic diagnostic features of and reporting guidelines for actinic keratosis (AK) and cutaneous squamous cell carcinoma (cSCC). OBJECTIVE To develop consensus recommendations regarding diagnostic criteria, nomenclature, and reporting of AK and cSCC. METHODS Literature review and cross-sectional multiround Delphi process including an international group of expert dermatopathologists followed by a consensus meeting. RESULTS Consensus was achieved regarding the key dermatopathologic features necessary for diagnosing cSCC, AK, and associated variants; grading of degree of cellular differentiation in cSCC; utility of immunohistochemistry for diagnosis of cSCC; and pathologic features that should be reported for cSCC and AK. LIMITATIONS Consensus was not achieved on all questions considered. CONCLUSION Despite the lack of clarity in the literature, there is consensus among expert dermatopathologists regarding diagnostic criteria and appropriate reporting of AK and cSCC. Widespread implementation of these consensus recommendations may improve communication between dermatopathologists and clinicians, facilitating appropriate treatment of AK and cSCC.

Abstract
Importance Laser-assisted drug delivery (LADD) is used for various medical and cosmetic applications. However, there is insufficient evidence-based guidance to assist clinicians performing LADD. Objective To develop recommendations for the safe and effective use of LADD. Evidence Review A systematic literature review of Cochrane Central Register of Controlled Trials, Embase, and MEDLINE was conducted in December 2019 to identify publications reporting research on LADD. A multidisciplinary panel was convened to draft recommendations informed by the systematic review; they were refined through 2 rounds of Delphi survey, 2 consensus meetings, and iterative review by all panelists until unanimous consensus was achieved. Findings Of the 48 published studies of ablative fractional LADD that met inclusion criteria, 4 were cosmetic studies; 21, oncologic; and 23, medical (not cosmetic/oncologic), and 6 publications of nonablative fractional LADD were included at the request of the expert panel, producing a total of 54 studies. Thirty-four studies (63.0%) were deemed to have low risk of bias, 17 studies (31.5%) had moderate risk, and 3 (5.5%) had serious risk. The key findings that informed the guidelines developed by the expert panel were as follows: LADD is safe in adults and adolescents (≥12 years) with all Fitzpatrick skin types and in patients with immunosuppression; it is an effective treatment for actinic keratosis, cutaneous squamous cell carcinoma in situ, actinic cheilitis, hypertrophic scars, and keloids; it is useful for epidermal and dermal analgesia; drug delivery may be increased through the application of heat, pressure, or occlusion, or by using an aqueous drug solution; laser settings should be selected to ensure that channel diameter is greater than the delivered molecule; antibiotic prophylaxis is not recommended, except with impaired wound healing; antiviral prophylaxis is recommended when treating the face and genitalia; and antifungal prophylaxis is not recommended. The guideline's 15 recommendations address 5 areas of LADD use: (I) indications and contraindications; (II) parameters to report; (III) optimization of drug delivery; (IV) safety considerations; and (V) prophylaxis for bacterial, viral, and fungal infections. Conclusions and Relevance This systematic review and Delphi consensus approach culminated in an evidence-based clinical practice guideline for safe and effective use of LADD in a variety of applications. Future research will further improve our understanding of this novel treatment technique.

Abstract
BACKGROUND The development of rigorous, high-quality clinical guidelines increases the need for resources and skilled personnel within guideline-producing organizations. While collaboration between organizations provides a unique opportunity to pool resources and save time and effort, the collaboration presents its own unique challenges. OBJECTIVE To assess the perceived needs and current challenges of guideline producers worldwide related to guideline development and collaboration efforts. DESIGN Survey questions were developed by the Guidelines International Network and the US GRADE Network, pilot-tested among attendees of a guideline development workshop, and disseminated electronically using convenience and snowball sampling methods. PARTICIPANTS A total of 171 respondents representing 30 countries and more than 112 unique organizations were included in this analysis. MAIN MEASURES The survey included free-response, multiple-choice, and seven-point Likert-scale questions. Questions assessed respondents' perceived value of guidelines, resource availability and needs, guideline development processes, and collaboration efforts of their organization. KEY RESULTS Time required to develop high-quality systematic reviews and guidelines was the most relevant need (median=7; IQR=5.5-7). In-house resources to conduct literature searches (median=4; IQR=3-6) and the resources to develop rigorous guidelines rapidly (median=4; IQR=2-5) were perceived as the least available resources. Difficulties reconciling differences in guideline methodology (median=6; IQR=4-7) and the time required to establish collaborative agreements (median=6; IQR=5-6) were the most relevant barriers to collaboration between organizations. Results also indicated a general need for improvement in conflict of interest (COI) disclosure policies. CONCLUSION The survey identified organizational challenges in supporting rigorous guideline development, including the time, resources, and personnel required. Connecting guideline developers to existing databases of high-quality systematic reviews and the use of freely available online platforms may facilitate guideline development. Guideline-producing organizations may also consider allocating resources to hiring or training personnel with expertise in systematic review methodologies or utilizing resources more effectively by establishing collaborations with other organizations.

Abstract
Objectives
During premarket review, the US Food and Drug Administration may ask its Medical Device Advisory Committee (MDAC) Panels to assess the safety and effectiveness of medical devices being considered for approval. The objective of this study is to assess the relationship, if any, between individual votes and Panel recommendations and: (1) the composition of Panels, specifically the expertise and demographic features of individual members; or (2) Panel members’ propensity to speak during Panel deliberations.
Methods
This was a retrospective cohort study of routinely collected data from voting members of MDAC panels convened between January 2011 to June 2016 to consider premarket approval. Data sources were verbatim transcripts available publicly from the FDA. Number of words spoken, directionality of votes on device approval, profession, and demographics were collected.
Results
658,954 words spoken by 536 members during 49 meetings of 11 Panels were analyzed. Based on multivariate analysis, biostatisticians spoke more (+373 words; P = 0.0002), and women (-187 words; P = 0.0184) and other non-physician voting members less (-213 words; P = 0.0306), than physicians. Speaking more was associated with abstaining (P = 0.0179), and with voting against the majority (P = 0.0153). Non-physician, non-biostatistician members (P = 0.0109), and those having attended more meetings as a voting member (P = 0.0249) were more likely to vote against approval. In bivariable analysis, unanimous Panels had a greater proportion of biostatisticians (mean 0.1580; 95% CI 0.1237–0.1923) than non-unanimous Panels (0.1107; 95% CI 0.0912–0.1301; p = 0.0201).
Conclusions
Panelists likely to vote against the majority include non-physician, non-biostatisticians; experienced Panelists; and more talkative members. The increased presence of biostatisticians on Panels leads to greater voting consensus. Having a diversity of opinions on Panels, including in sufficient numbers those members likely to dissent from majority views, may help ensure that a diversity of opinions are aired before decision-making.

Abstract
Physical forces associated with spaceflight and spaceflight analogue culture regulate a wide range of physiological responses by both bacterial and mammalian cells that can impact infection. However, our mechanistic understanding of how these environments regulate host-pathogen interactions in humans is poorly understood. Using a spaceflight analogue low fluid shear culture system, we investigated the effect of Low Shear Modeled Microgravity (LSMMG) culture on the colonization of Salmonella Typhimurium in a 3-D biomimetic model of human colonic epithelium containing macrophages. RNA-seq profiling of stationary phase wild type and Δhfq mutant bacteria alone indicated that LSMMG culture induced global changes in gene expression in both strains and that the RNA binding protein Hfq played a significant role in regulating the transcriptional response of the pathogen to LSMMG culture. However, a core set of genes important for adhesion, invasion, and motility were commonly induced in both strains. LSMMG culture enhanced the colonization (adherence, invasion and intracellular survival) of Salmonella in this advanced model of intestinal epithelium using a mechanism that was independent of Hfq. Although S. Typhimurium Δhfq mutants are normally defective for invasion when grown as conventional shaking cultures, LSMMG conditions unexpectedly enabled high levels of colonization by an isogenic Δhfq mutant. In response to infection with either the wild type or mutant, host cells upregulated transcripts involved in inflammation, tissue remodeling, and wound healing during intracellular survival. Interestingly, infection by the Δhfq mutant led to fewer transcriptional differences between LSMMG- and control-infected host cells relative to infection with the wild type strain. This is the first study to investigate the effect of LSMMG culture on the interaction between S. Typhimurium and a 3-D model of human intestinal tissue. These findings advance our understanding of how physical forces can impact the early stages of human enteric salmonellosis.

Abstract
Importance It has been suggested that Mohs surgery for skin cancer among individuals with limited life expectancy may be associated with needless risk and discomfort, along with increased health care costs. Objective To investigate patient- and tumor-specific indications considered by clinicians for treatment of nonmelanoma skin cancer in older individuals. Design, Setting, and Participants This multicenter, prospective cohort study was conducted using data from US private practice and academic centers. Included patients were those older than age 85 years presenting for skin cancer surgery and referred for Mohs surgery, with reference groups of those younger than age 85 years receiving Mohs surgery and those older than age 85 years not receiving Mohs surgery. Data were analyzed from November 2018 through January 2019. Exposures Mohs surgery for nonmelanoma skin cancer. Main Outcomes and Measures Reason for treatment selection. Results Among 1181 patients older than age 85 years referred for Mohs surgery (724 [61.9%] men among 1169 patients with sex data; 681 individuals aged >85 to 88 years [57.9%] among 1176 patients with age data) treated at 22 sites, 1078 patients (91.3%) were treated by Mohs surgery, and 103 patients (8.7%) received alternate treatment. Patients receiving Mohs surgery were more likely to have tumors on the face (738 patients [68.5%] vs 26 patients [25.2%]; P < .001) and nearly 4-fold more likely to have high functional status (614 patients [57.0%] vs 16 patients [15.5%]; P < .001). Of 15 distinct reasons provided by surgeons for opting to proceed with Mohs surgery, the most common were patient desire for treatment with a high cure rate (712 patients [66.0%]), good or excellent patient functional status for age (614 patients [57.0%]), and high risk associated with the tumor based on histology (433 patients [40.2%]). Conclusions and Relevance This study found that older patients who received Mohs surgery often had high functional status, high-risk tumors, and tumors located on the face. These findings suggest that timely surgical treatment may be appropriate in older patients given that their tumors may be aggressive, painful, disfiguring, and anxiety provoking.

Abstract
IMPORTANCE Extramammary Paget disease (EMPD) is a frequently recurring malignant neoplasm with metastatic potential that presents in older adults on the genital, perianal, and axillary skin. Extramammary Paget disease can precede or occur along with internal malignant neoplasms. OBJECTIVE To develop recommendations for the care of adults with EMPD. EVIDENCE REVIEW A systematic review of the literature on EMPD from January 1990 to September 18, 2019, was conducted using MEDLINE, Embase, Web of Science Core Collection, and Cochrane Libraries. Analysis included 483 studies. A multidisciplinary expert panel evaluation of the findings led to the development of clinical care recommendations for EMPD. FINDINGS The key findings were as follows: (1) Multiple skin biopsies, including those of any nodular areas, are critical for diagnosis. (2) Malignant neoplasm screening appropriate for age and anatomical site should be performed at baseline to distinguish between primary and secondary EMPD. (3) Routine use of sentinel lymph node biopsy or lymph node dissection is not recommended. (4) For intraepidermal EMPD, surgical and nonsurgical treatments may be used depending on patient and tumor characteristics, although cure rates may be superior with surgical approaches. For invasive EMPD, surgical resection with curative intent is preferred. (5) Patients with unresectable intraepidermal EMPD or patients who are medically unable to undergo surgery may receive nonsurgical treatments, including radiotherapy, imiquimod, photodynamic therapy, carbon dioxide laser therapy, or other modalities. (6) Distant metastatic disease may be treated with chemotherapy or individualized targeted approaches. (7) Close follow-up to monitor for recurrence is recommended for at least the first 5 years. CONCLUSIONS AND RELEVANCE Clinical practice guidelines for EMPD provide guidance regarding recommended diagnostic approaches, differentiation between invasive and noninvasive disease, and use of surgical vs nonsurgical treatments. Prospective registries may further improve our understanding of the natural history of the disease in primary vs secondary EMPD, clarify features of high-risk tumors, and identify superior management approaches.

Abstract
A COS is a systematically developed list of outcomes recommended for reporting all studies within a particular disease area. The Cochrane Skin–Core Outcome Set Initiative (CS-COUSIN) and the Core Outcome Measures in Food Allergy (COMFA) Initiative Joint Meeting was held virtually on September 23 through 28, 2021. This meeting brought together core outcome set (COS) developers within the domains of dermatology and food allergy, respectively. The meeting assessed the state of COS methodology, provided a forward look, and facilitated the networking of members of individual COS groups. The meeting hosted several expert-led key addresses and focus sessions, in which work was critically discussed, new developments were shared, and groundwork was laid for future projects. The conference emphasized the importance of ongoing COS work to improve patient outcomes and limit research waste.

Abstract
INTRODUCTION Melasma is a pigmentation disorder of the skin. Characterised by brown to gray-brown patches on the face and neck, the condition predominantly affects women and has been associated with pregnancy, hormonal variation and sun exposure. Melasma can be disfiguring and anxiety-provoking, and quality of life is often adversely impacted. Management includes sun protection, laser and energy device therapy, topical and oral skin-bleaching agents and chemical peels. While clinical trials of melasma exist, there is a lack of consistency in reported outcomes, which has been a barrier to the aggregation of data in systematic reviews and meta-analyses. This protocol describes a planned process for development of a minimum set of outcomes (ie, 'core outcome set') that should be measured in all clinical trials of melasma. METHODS AND ANALYSIS An exhaustive list of potential outcomes will be extracted from four sources: (1) systematic literature review of outcomes in clinical trials; (2) semistructured patient interviews; (3) brochures, pamphlets, clinical trial registries, and other published and unpublished sources and documentation; and (4) interviews with non-patient, non-physician stakeholders, including federal regulators, industry scientists and non-physician providers. An international two-round Delphi process will then be performed to identify the outcomes deemed most important to patients and physicians. Subsequently, a consensus meeting will be convened to review and process the results, and to vote on a final set of core outcomes. ETHICS AND DISSEMINATION Ethics approval was provided by the Northwestern University Institutional Review Board (protocol ID: STU00201637). This study is registered with both the Core Outcome Measures in Effectiveness Trials and Cochrane Skin-Core Outcome Set Initiative initiatives, and this protocol is in accordance with the guidelines for protocol development of both groups. All findings from the study described in this protocol will be disseminated to all stakeholders involved in the development process and will be submitted for publication in peer-reviewed journals. PROSPERO REGISTRATION NUMBER CRD42020214189.

Abstract
Core outcome sets, or the minimum sets of outcomes that would be used in all clinical studies of a given disease or condition, have the potential to revolutionize clinical research in laser and energy devices. Currently, laser studies, like other clinical investigations in medicine, measure whatever outcomes the individual investigators deem appropriate, making it difficult to compare safety and efficacy of various treatments through meta-analyses. The development of core outcome sets is rigorous, and involves systematic literature reviews, interviews with various stakeholders such as industry researchers, regulatory bodies, non-physician providers, patients and family members, as well as an international Delphi consensus process with input from both patients and physicians. Following the establishment of core outcome sets, core outcome measures are developed, with one measure being the preferred means for assessing each core outcome. Uptake of core outcome sets and measures can make it much easier to combine the results of different studies of the same condition across treatment modalities and geographic regions. Once researchers are all reporting, at a minimum, the same outcomes and using the same outcome measures, patients will truly be well-served, and we will then be working cooperatively, worldwide, to answer the same important questions. In doing so, we will move the science of laser medicine forward.

Abstract
Porokeratosis is a rare diagnosis in the pediatric population, and eruptive disease has been documented prior in patients with history of stem cell transplantation. Comparing various porokeratosis eruptions between patients can be difficult due to limitations in current classification and nomenclature. Here, we discuss a single-institution case series of three children who developed porokeratosis following hematopoietic stem cell transplantation for acute leukemia, and we propose that this presentation be termed localized eruptive porokeratosis (LEP). We present the distinguishing features of this variant by discussing the shortcomings in current nomenclature and also examine the association between porokeratosis and hematopoietic stem cell transplantation in the pediatric population.

Abstract
Importance Soft-tissue augmentation with skin fillers can be delivered with needles or microcannulas, but unwanted vascular occlusions are possible. Objective To determine whether filler-associated vascular occlusion events of the face occur more often with injections performed with needles than with microcannulas. Design, Setting, and Participants This retrospective cohort study included a random sample of board-certified dermatologists deemed eligible based on membership in relevant professional societies and attendance at relevant national professional meetings. Participants completed detailed forms in which they could enter deidentified data and volume statistics pertaining to patients undergoing filler procedures in their practices. Data were collected from August 2018 to August 2019. Exposures Injectable fillers approved by the US Food and Drug Administration delivered via needles or microcannulas. Main Outcomes and Measures The primary outcome measure was intravascular occlusion. Occlusion events were graded by severity (no sequelae, scar, and ocular injury or blindness). Results A total of 370 dermatologists (mean [SD] years in practice, 22.3 [11.1] years) participated and reported 1.7 million syringes injected. The risk of occlusion with any particular filler type using needle or cannula never exceeded 1 per 5000 syringes injected. Overall, 1 occlusion per 6410 per 1-mL syringe injections was observed with needles and 1 per 40 882 with cannulas (P < .001). Of the 370 participants, 106 (28.6%) reported at least 1 occlusion. Multivariate analysis found that injections with cannula had 77.1% lower odds of occlusion compared with needle injections. Participants injecting fillers for more than 5 years had 70.7% lower odds of occlusion than those who were less experienced. For each additional injection per week, the odds of occlusion decreased by 1%, and 85% of occlusions had no long-term sequelae. Nasolabial folds and lips were most likely to be occluded, with mean severity level of occlusions highest at the glabella. Conclusions and Relevance In this cohort study, filler injections with either needles or cannulas were associated with a very low risk of intravascular occlusion events. Moreover, the vast majority of such events were minor and resolved without scar or other injury. Injections with microcannulas were less often associated with occlusion events than injections with needles. Occlusion risk per syringe appeared decreased after the first few years of clinical practice and was also lower among those who more frequently inject fillers. Whether a needle or cannula is most appropriate for injection may depend on patient factors, anatomic site, and the type of defect being treated.

Abstract
The CAPER Registry is a voluntary, national safety reporting program that gathers patients' adverse events encountered during dermatologic procedures. This registry is intended as an aid for practitioners, patients, industry, and government regulators, and aims to facilitate safety monitoring for the specialty by identifying resource, process, education, and other systemic gaps associated with adverse events, as well as any potential risk factors for adverse events. CAPER will provide new or corroborating information to help dermatologists improve clinical practices, improve safety and effectiveness, and treat and prevent adverse events. The data generated will also help industry partners and regulatory bodies prevent adverse events from going unnoticed.

Abstract
BACKGROUND Stromal vascular fraction (SVF), derived enzymatically or mechanically from adipose tissue, contains a heterogenous population of cells and stroma, including multipotent stem cells. The regenerative capacity of SVF may potentially be adapted for a broad range of clinical applications, including the healing of acute cutaneous wounds. OBJECTIVE To evaluate the available literature on the efficacy and safety of autologous adipose-derived stromal vascular fraction (SVF) for the treatment of acute cutaneous wounds in humans. METHODS A systematic review of the literature utilizing MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials was performed to identify published clinical trials of autologous adipose-derived SVF or similar ADSC-containing derivatives for patients with acute cutaneous wounds. This was supplemented by searches for ongoing clinical trials through ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. RESULTS 872 records were initially retrieved. Application of inclusion and exclusion criteria yielded 10 relevant studies: two completed non-randomized controlled trials and eight ongoing clinical trials. Both completed studies reported a statistically significant benefit in percentage re-epithelialization and time to healing for the SVF treatment arms. Safety information for SVF was not provided. Ongoing clinical trials were assessing outcomes such as safety, patient and observer reported scar appearance, wound healing rate, and wound epithelization. CONCLUSION In the context of substantial limitations in the quantity and quality of available evidence, the existing literature suggests that SVF may be a useful treatment for acute cutaneous wounds in humans. More clinical trials with improved outcome measures and safety assessment are needed.

Abstract
BACKGROUND After Congress passed the Drug Quality and Security Act (DQSA) in 2013, new rules led to increased oversight of compounding pharmacies and also draft guidance relating to compounding in physicians' offices. OBJECTIVE To gather information from state medical board directors about the nature and frequency of reported adverse events associated with compounding in physicians' offices, and board policies regarding the regulation of such compounding. DESIGN Cross-sectional survey study. Participants were surveyed regarding: (1) the number of compounding-associated adverse events in physician offices; and (2) the extent to which their board implements United States Pharmacopeia (USP) standards on physician office compounding. SETTING Remote data collection at an academic medical center. PARTICIPANTS Executive directors or comparable executives of state medical and osteopathic boards. MEASUREMENTS Adverse event reports associated with medications compounded in physician offices. State board rules consistent with USP compounding standards for physician offices. RESULTS Seventy percent of state boards (47/67) responded, with 42 complete responses analyzed. The majority (71%) of boards able to provide information on compounding errors had received no reports of these. None of the reported errors were known to have resulted in patient harm. Ninety percent of respondents had not incorporated any USP compounding standards into their regulations. CONCLUSION These findings suggest that the incidence of adverse events associated with in-office compounding is low, and that this may be limiting the propensity of state medical and osteopathic boards to implement strict regulations, such as USP compounding standards, that would further restrict such compounding. Therefore, regulatory agencies and legislators would better serve their mission by reallocating resources to ensure the integrity of other aspects of the drug supply chain.

Abstract
Postinflammatory hyperpigmentation (PIH) is a disorder of pigmentation that is a common presenting complaint, especially in individuals with skin of color. It is associated with a significant psychological burden and decrement of quality of life. Management options include photoprotection, topical lightening agents, and lasers and energy devices. Clinical trials of melasma report a diversity of outcomes, which often impedes synthesis of results across trials, or comparison of results associated with different treatment modalities. This protocol describes the design of a consensus process that would culminate in the development of a core set of outcomes to be assessed in all clinical trials for PIH. A long list of candidate outcomes will be developed through a systematic review, combined with semi-structured interviews with various stakeholders, including patients, scientists, regulators, and health care professionals. This long list of outcomes will be reviewed and refined by a steering committee. Then two rounds of Delphi surveys of patient and physician groups, respectively, will be used to cull the list, with provisional inclusion of those items deemed "important" by 70% of the respondents. A consensus meeting will be held virtually or in person to vote on these items, and also to consider any changes necessary before acceptance of a final core outcome set. Development of a core outcome set for PIH is expected to improve and standardize outcomes reporting in current and future clinical trials. This, in turn, may facilitate aggregation of research results and permit comparison of outcomes across multiple studies.

Abstract
IMPORTANCE Nonscarring alopecia, including androgenetic alopecia and alopecia areata, are common and can negatively impact quality of life. Recent clinical studies have investigated autologous, adipose-derived stromal vascular fraction (SVF) as a potentially beneficial treatment option. OBJECTIVE To assess the available evidence on the utility and safety of SVF for nonscarring alopecia. EVIDENCE REVIEW A systematic review of the literature was performed using MEDLINE (PubMed), Embase, and CENTRAL from inception to November 2020. Included articles were prospective, observational or interventional studies of SVF for nonscarring alopecia in humans. FINDINGS Six studies of 188 patients were identified, including three randomized controlled trials. There were no reported severe adverse events. All studies found improved hair density with SVF compared to control or pre-treatment baseline. One study reported that improvement in hair density varied based on time for follow-up, severity of hair loss, and concentration of adipose-derived stem cells (ADSCs) within the SVF. Two studies reported an increase in hair diameter from baseline, and two studies reported an improvement in hair pull test outcomes. CONCLUSIONS AND RELEVANCE SVF may be safe and effective for nonscarring alopecia in the appropriate patients. Hair loss severity, method of SVF preparation and frequency of treatment, and adjunctive therapies may be important considerations for treatment success. Additional studies evaluating appropriate patient selection and treatment methods are needed.

Abstract
Psoriasis, which affects up to 2% of children may be associated with significant comorbidity, including obesity, diabetes, cardiovascular disease, depression, and reduced quality of life. Screening and decision-making require a multidisciplinary approach with the management of potential comorbidities championed by primary care providers and supported by respective specialists and subspecialists. Research into the comorbidities and systemic manifestations has generated significant data culminating in several proposals for a consensus guideline for both pediatric and nonpediatric populations. Our aim is to provide a summary targeted to the pediatric primary care provider from the best available evidence when caring for children with psoriasis.

Samarium hexaboride is a candidate for the topological Kondo insulator state, in which Kondo coherence is predicted to give rise to an insulating gap spanned by topological surface states. Here we investigate the surface and bulk electronic properties of magnetically alloyed Sm_{1-x}M_{x}B_{6} (M=Ce, Eu), using angle-resolved photoemission spectroscopy and complementary characterization techniques. Remarkably, topologically nontrivial bulk and surface band structures are found to persist in highly modified samples with up to 30% Sm substitution and with an antiferromagnetic ground state in the case of Eu doping. The results are interpreted in terms of a hierarchy of energy scales, in which surface state emergence is linked to the formation of a direct Kondo gap, while low-temperature transport trends depend on the indirect gap.

Abstract
BACKGROUND The lack of uniformity in the outcomes reported in clinical studies of the treatment of cutaneous squamous cell carcinoma (cSCC) complicates efforts to compare treatment effectiveness across trials. OBJECTIVES To develop a core outcome set (COS), a minimum set of agreed-upon outcomes to be measured in all clinical trials of a given disease or outcome, for the treatment of cSCC. METHODS One hundred and nine outcomes were identified via a systematic literature review and interviews with 28 stakeholders. After consolidation of this long list, 55 candidate outcomes were rated by 19 physician and 10 patient stakeholders, in two rounds of Delphi exercises. Outcomes scored 'critically important' (score of 7, 8 or 9) by ≥ 70% of patients and ≥ 70% of physicians were provisionally included. At the consensus meeting, after discussion and voting of 44 international experts and patients, the provisional list was reduced to a final core set, for which consensus was achieved among all meeting participants. RESULTS A core set of seven outcomes was finalized at the consensus meeting: (i) serious or persistent adverse events, (ii) patient-reported quality of life, (iii) complete response, (iv) partial response, (v) recurrence-free survival, (vi) progression-free survival and (vii) disease-specific survival. CONCLUSIONS In order to increase the comparability of results across trials and to reduce selective reporting bias, cSCC researchers should consider reporting these core outcomes. Further work needs to be performed to identify the measures that should be reported for each of these outcomes.

Abstract
Paramagnetic heavy fermion insulators consist of fully occupied quasiparticle bands inherent to Fermi liquid theory. The gap emergence below a characteristic temperature is the ultimate sign of coherence for a many-body system, which in addition can induce a non-trivial band topology. Here, we demonstrate a simple and efficient method to compare a model study and an experimental result for heavy fermion insulators. The temperature dependence of the gap formation in both local moment and mixed valence regimes is captured within the dynamical mean field (DMFT) approximation to the periodic Anderson model (PAM). Using the topological coherence temperature as the scaling factor and choosing the input parameter set within the mixed valence regime, we can unambiguously link the theoretical energy scales to the experimental ones. As a particularly important result, we find improved consistency between the scaled DMFT density of states and the photoemission near-gap spectra of samarium hexaboride (SmB6).

Abstract
We investigate temperature-dependent carrier dynamics of InAs crystal by using reflection-type terahertz time-domain spectroscopy, particularly with a recently developed emitter-sample hybrid structure. We successfully obtain the optical conductivity in a terahertz frequency of bulk InAs whose dc conductivity is in the range of 100-150 Ω-1 cm-1. We find that both real and imaginary parts of the optical conductivity can be fit well with the simple Drude model, and the free-carrier density and the scattering rate obtained from the fit are in good agreement with corresponding values obtained by using other techniques, such as the Hall measurement and the dc-resistivity measurement. These results clearly demonstrate that the proposed technique of adopting the emitter-sample hybrid structure can be exploited to determine temperature-dependent optical constants in a reflection geometry and hence to investigate electrodynamics of bulk metallic systems.

Abstract
Half-filled electron systems, even with the maximized spin angular moment, have been given little attention because of their zero-orbital angular moment according to Hund's rule. Nevertheless, there are several measurements that show evidence of a nonzero orbital moment as well as spin-orbit coupling. Here we report for the first time the orbital order in a half-filled 4f-electron system GdB_{4}, using the resonant soft x-ray scattering at Gd M_{4,5}-edges. Furthermore, we discovered that the development of this orbital order is strongly coupled with the antiferromagnetic spin order. These results clearly demonstrate that even in half-filled electron systems the orbital angular moment can be an important parameter to describe material properties, and may provide significant opportunities for tailoring new correlated electron systems.

Abstract
OBJECTIVE The purpose of this study was to determine how the energies supplied from a cosmetic vibrator are deeply or far transferred into organs and tissues, and how these depths or distances are influenced by tissue elasticity. METHODS External vibration energy was applied to model skin surfaces through a facial cleansing vibrator, and we measured a distance- and depth-dependent energy that was transferred to model skin matrices. As model skin matrices, we synthesized hard and soft poly(dimethylsiloxane) (PDMS) gels, as well as hydrogels with a modulus of 2.63 MPa, 0.33 MPa and 21 kPa, respectively, mostly representing those of skin and other organs. The transfer of vibration energy was measured either by increasing the separation distances or by increasing the depth from the vibrator. RESULTS The energies were transmitted deeper into the hard PDMS than into the soft PDMS and hydrogel matrices. This finding implies that the vibration forces influence a larger area of the gel matrices when the gels are more elastic (or rigid). There were no appreciable differences between the soft PDMS and hydrogel matrices. However, the absorbed energies were more concentrated in the area closest to the vibrator with decreasing elasticity of the matrix. Softer materials absorbed most of the supplied energy around the point of the vibrator. In contrast, harder materials scattered the external energy over a broad area. CONCLUSIONS The current results are the first report in estimating how the external energy is deeply or distantly transferred into a model skins depending on the elastic moduli of the models skins. In doing so, the results would be potentially useful in predicting the health of cells, tissues and organs exposed to various stimuli.

Abstract
To finally resolve the controversial issue of whether or not the electronic structure of YbB_{6} is nontrivially topological, we have made a combined study using angle-resolved photoemission spectroscopy (ARPES) of the nonpolar (110) surface and density functional theory (DFT). The flat-band conditions of the (110) ARPES avoid the strong band bending effects of the polar (001) surface and definitively show that YbB_{6} has a topologically trivial B 2p-Yb 5d semiconductor band gap of ∼0.3 eV. Accurate determination of the low energy band topology in DFT requires the use of a modified Becke-Johnson exchange potential incorporating spin-orbit coupling and an on-site Yb 4f Coulomb interaction U as large as 7 eV. The DFT result, confirmed by a more precise GW band calculation, is similar to that of a small gap non-Kondo nontopological semiconductor. Additionally, the pressure-dependent electronic structure of YbB_{6} is investigated theoretically and found to transform into a p-d overlap semimetal with small Yb mixed valency.

Abstract
The aims of this study were to establish a random amplified polymorphic DNA (RAPD) fingerprint database of chloroplast DNA (cpDNA) from different cultivars of Cornus officinalis and to convert RAPD markers to sequence characterized amplified regions (SCAR) markers. A method of extraction was established that was suitable for obtaining cpDNA from samples rapidly dried in silicone; an RAPD fingerprint database was built; and the genetic distance between samples was used as statistical clustering variables for calculating DICE genetic similarity coefficients and for building a kinship tree chart. RAPD markers were converted to SCAR markers to design specific primers, and samples from C. officinalis cultivars, plants of the same family, and its adulterants, were used for amplification and identification. Fifteen amplified primers with stable polymorphisms were screened for amplification of 130 copies of materials. In total, 57 sites were achieved, 40 of which were polymorphic, and the polymorphic rate was up to 70.18%. A genetic tree was built based on seven cultivars. SCAR markers of C. officinalis cpDNA were successfully converted into RAPD markers. cpDNA samples from hawthorn, C. officinalis, Cornus wood, and grape were used for SCAR amplification, and their bands were distinctly different. In conclusion, SCAR markers and cpDNA may be used for research on C. officinalis and its adulterants, and the results may provide a basis for identifying germplasm and screening fine varieties at a molecular level.

Abstract
Typical Kondo insulators (KIs) can have a nontrivial Z_{2} topology because the energy gap opens at the Fermi energy (E_{F}) by a hybridization between odd- and even-parity bands. SmB_{6} deviates from such KI behavior, and it has been unclear how the insulating phase occurs. Here, we demonstrate that charge fluctuations are the origin of the topological insulating phase in SmB_{6}. Our angle-resolved photoemission spectroscopy results reveal that with decreasing temperature the bottom of the d-f hybridized band at the X[over ¯] point, which is predicted to have odd parity and is required for a topological phase, gradually shifts from below to above E_{F}. We conclude that SmB_{6} is a charge-fluctuating topological insulator.
