The miR156 juvenility factor and PLETHORA 2 form a regulatory network and influence timing of meristem growth and lateral root emergence.

Plants develop throughout their lives: seeds become seedlings that mature and form fruits and seeds. Although the underlying mechanisms that drive these developmental phase transitions have been well elucidated for shoots, the extent to which they affect the root is less clear. However, root anatomy does change as some plants mature; meristems enlarge and radial thickening occurs. Here, in Arabidopsis thaliana, we show that overexpressing miR156A, a gene that promotes the juvenile phase, increased the density of the root system, even in grafted plants in which only the rootstock had the overexpression genotype. In the root, overexpression of miR156A resulted in lower levels of PLETHORA 2, a protein that affects formation of the meristem and elongation zone. Crossing in an extra copy of PLETHORA 2 partially rescued the effects of miR156A overexpression on traits affecting root architecture, including meristem length and the rate of lateral root emergence. Consistent with this, PLETHORA 2 also inhibited the root-tip expression of another miR156 gene, miR156C. We conclude that the system driving phase change in the shoot affects developmental progression in the root, and that PLETHORA 2 participates in this network.

Plastic Surgery Training During Coronavirus Disease 2019 Pandemic: A Quantitative Study on Trainees' Wellness and Education.

PURPOSE: Coronavirus disease 2019 (COVID-19) pandemic has had far reaching impacts on all aspects of the healthcare system, including plastic surgery training. Due to reduction in the number of elective surgery cases and need for social distancing, plastic surgery education has shifted from the operating room to the virtual learning environment. Although these changes have been qualitatively described, the authors present a quantitative analysis of plastic surgery training changes due to the COVID-19 pandemic. Our study has identified residents' greatest impediments and inquired about suggestions for further improvements. Our goal is to help residency programs through the COVID-19 pandemic era and contribute to future guidelines when residency education encounters additional unexpected changes. METHODS: An institutional review board approved anonymous survey using Qualtrics was forwarded on April 23, 2020 to US plastic surgery program directors to be distributed to plastic surgery residents and fellows. Questions centered on the impact of COVID-19 on residents' well-being, education and career plans results were collected for data analysis. Residents were given the option to be in a raffle to win a $50 amazon gift card. Completion of the survey was both anonymous and voluntary. RESULTS: A total of 69 trainees responded (52 integrated residents and 17 independent fellows) from 18 states. Fifty-one percent were male and 49% were female. Fifty-six percent of trainees plan to complete a fellowship program after graduation, 31% will join private practice. Nine percent of trainees reported changes in their postgraduation plans due to the pandemic, 67% were senior trainees. Of those whose goals were affected by COVID-19 pandemic, 56% opted to pursue additional fellowship training. They described reduced operative exposure and cancelations of elective surgeries (50%), the limited availability of private practice jobs (37.5%), and financial reasons (12.5%) for their decision. Twelve percent reported being concerned about not meeting the necessary requirements to finish their residency and graduate on time. Seventy-six percent of trainees expressed concerns about the health and safety of themselves, family and loved ones. Forty-nine percent of trainees reported increased levels of stress since the onset of the pandemic. Ninety-seven percent of trainees reported having reduction in their operative time during the COVID-19 pandemic. They utilized their nonoperative time for online education modules (84%), educational readings (82%), and research (80%). Plastic surgery trainees learned about national webinars through emails from professional society (83%), co-resident/fellow (77%), program director emails (74%), and social media (22%). Webinars attended were mostly through virtual platform modalities, among which Zoom and Webex were the most preferred. Less interactions with colleagues and faculty was the biggest barrier to adopting virtual conferences. Despite this, 72% agreed that having grand rounds, didactics and journal clubs online increased attendance. Additionally, 88% of respondents expressed interests in attending professional society sponsored virtual grand rounds in the future. CONCLUSIONS: Results from our survey demonstrated that the overwhelming majority of plastic surgery residents have had reductions in operative times and widespread curriculum changes during the COVID-19 pandemic. These recent changes have increased residents' stress levels and adversity affected their future career plans. Additionally, COVID-19 has heralded an increase in virtual conferences and learning modules. Plastic surgery trainees expressed a preference for virtual educational platforms and interest in continuing virtual didactics in the future. This may irreversibly change the landscape of future plastic surgery training.

Word of Mouth and Online Reviews Are More Influential Than Social Media for Patients When Selecting a Sports Medicine Physician.

Purpose: To (1) identify the percentage of patients seen in an orthopaedic sports medicine practice who use social media and (2) identify the role that social media has in physician selection as compared with other factors. Methods: After institutional review board approval was received, new patients aged 18 years or older who attended a single orthopaedic sports medicine office from February 2020 to May 2021 were identified for inclusion. Sociodemographic information was recorded, and each patient was asked to fill out a questionnaire that assessed social media usage and online resources used to choose and formulate opinions regarding the patient's provider. Results: Two hundred patients met the inclusion criteria and completed the questionnaire. Of these, 96.5% reported social media use. The most common online method of searching for and identifying a physician was Google (50.5%). Social media outlets such as Facebook, Instagram, or LinkedIn were only used 15.5% of the time to search for and select a physician. Older patients were more likely to use recommendations from friends and family in their consideration when selecting a physician. Conclusions: Despite almost all participants stating that they use social media, only 15.5% of patients reported that they used social media to search for and potentially select their physician. Our study suggests that although social media can be a helpful tool for patient education, other factors such as physician education and physician reputation through word-of-mouth referrals, online reviews, and online ratings seem to play a larger role in the patient's selection of his or her physician. Clinical Relevance: This information may be of value to orthopaedic surgeons looking for ways to build their patient base, online reputation, or other aspects of their practice on the Internet.

Reflecting on Plastic Surgery Training During Early COVID-19 Pandemic: Resident Exposure and Telemedicine.

PURPOSE: Coronavirus disease 2019 (COVID-19) pandemic has been an unprecedented public health crisis. As hospitals took measures to increase their capacity to manage COVID-19 patients, plastic surgeons have also had to modify their routine to continue serving their vital role within the hospital environment. In an effort to reduce exposure to COVID-19 and conserve hospital resources, many plastic surgery programs drastically modified call schedules, restructured inpatient teams, triaged operative cases, and expanded telemedicine encounters. Plastic surgery programs focused on craniofacial procedures were impacted by precautionary preventative protocol and shifts in case load made to protect both the healthcare teams and the patients. At academic centers, plastic surgery trainees of all domains felt the impact of these changes. Recognizing the implications on future craniofacial surgical practice, the pandemic has made, the goal of the authors' study is to measure initial impacts of COVID-19 on plastic surgery trainees using a nationwide survey. The authors' results present the first quantitative analysis of plastic surgery trainees' exposure to COVID-19, deployment to other medical specialties, usage of personal protective equipment, and implementation of telemedicine during the pandemic. While healthcare systems have greatly adapted to pandemic complications and can anticipate vaccination, resurgence of COVID-19 cases linked to the delta variant heightens the authors' urgency in understanding the early pandemic, and its lasting impacts on healthcare. In the months following pandemic onset, telemedicine has become a mainstay in healthcare, trainees have adapted and become integrated in patient care in novel ways, and visits unable to transition to telemedical settings received substantial attention to ensure patient and provider safety. METHODS: An institutional review board-approved anonymous, multiple-choice and short-answer, Qualtrics survey regarding plastic surgery resident experiences with COVID-19 exposure. It was sent to all US plastic surgery program directors and program coordinators on April 23, 2020 with the request to distribute the survey to their residents. Residents were given the option to participate in a raffle for a $50 gift card. Outcomes measured included demographics, exposure to COVID-19, availability of resources, and adjustments to residency training practices. RESULTS: Sixty-nine plastic surgery residents throughout all years of training from 18 states responded. Gender, year of training, and location did not significantly impact these reports.Sixteen percent of residents reported covering a COVID-19 team. Twelve percent reported covering a shift not within their scope of practice. From these reports, residents mostly worked in the intensive care unit (50%) and the emergency department (29%).Half of the residents believe they were exposed to high-risk patients. This was reported in a variety of settings: the emergency department for plastic surgery consults (34%), caring for plastic surgery inpatients (16%), performing trauma reconstruction surgery (16%), cancer reconstruction surgery (12%), elective surgery (6%), and intraoperative consults (6%).Seventy-two percent of residents reported adequate access to personal protective equipment. Equipment type varied by patient exposure. When attending to a non-COVID-19 inpatient, most residents used a standard mask (62%) rather than an N95 mask (21%). N95 masks were generally used in patients with unknown COVID-19 status. Residents reported using eye and face shields when attending to non-COVID-19 ICU patients (17%), patients with unknown COVID-19 status (27%), and in the operating room (34%).Forty percent of residents implemented telemedicine to see patients for new consults, follow-up visits, postop checks, and wound checks. Eighty-five percent of residents report that they would continue to incorporate telemedicine in the future. Most significant reported barrier to using telemedicine is the limited ability to perform a physical examination (33%) followed by limited patient access to telemedicine (21%). Other challenges included poor ease of use for patients or providers, billing questions, and lack of interpersonal connection with patients. CONCLUSION: This study, to the best of the authors' knowledge, is the first to quantitatively investigate how plastic surgery residents have been affected by the widespread impacts of the COVID-19 pandemic. It reports resident exposure to COVID-19 and their associated concerns, resident access to and perceived adequacy of personal protective equipment, as well as changes to clinical practice.

Current Measurement Strategies of Coronal Tibiofemoral Subluxation: A Systematic Review of Literature.

OBJECTIVE. Coronal tibiofemoral (TF) subluxation has generated interest in the last several years due to newfound clinical implications of its presence. However, controversy within the literature concerning how to measure and calculate coronal TF subluxation on radiographic imaging remains. The purpose of this study was to describe how coronal TF subluxation is being measured and calculated in the literature with the goal of describing a reproducible and validated technique for clinical adoption. MATERIALS AND METHODS. A PubMed literature search was performed in March 2020 according to PRISMA guidelines. The terms "tibiofemoral subluxation" and "tibial femoral subluxation" were included in the search. Criteria of interest included radiographic view and evaluation, anatomic landmarks used, and measurement validity. RESULTS. Review of relevant literature resulted in 744 articles, 16 of which met our inclusion criteria. A wide range of measuring techniques, anatomic landmarks, and radiographic views were used with varying validity. Full-limb radiographic views were the most common. Six studies measured the translation of the mechanical axes of the tibia and femur. Eight studies measured the translation of either femoral condyle in reference to the tibial plateau. Coordinate-based software with the iterative closest point algorithm was used in two studies. Whether coronal TF subluxation should be divided by tibial plateau width to account for knee size was controversial. CONCLUSION. A variety of approaches exist for diagnosing and quantifying coronal TF subluxation because of the lack of clear anatomic landmarks within the TF joint that can be used to measure coronal TF subluxation in the horizontal plane. Even when using the same anatomic landmarks, studies varied on how to measure coronal TF subluxation radiographically and whether knee size should be accounted for. Further studies are necessary to standardize (via inter- and intraobserver validation with a control group) an easy, reproducible, and minimally biased approach to measuring coronal TF subluxation on radiographic imaging. We believe our systematic review succinctly provides the necessary information to either develop such a tool or encourage future studies to compare existing techniques to find the most reliable and clinically useful approach for evaluating coronal TF subluxation.

Healing Adjuncts in Craniofacial Surgery: Review of Dietary Vitamins and Supplements.

BACKGROUND: In the United States, the use of herbal supplements on a regular basis ranges from 32% to 97%. Prevalence of supplement use is particularly elevated after facial surgery. It has been reported as high as 50%. Unfortunately, there is a paucity of literature on the dietary use of supplements. They are not regulated by the FDA. Often, they are not reported by patients. This study examines the role of dietary supplements as adjuncts to healing in craniofacial and facial aesthetic surgeries. METHODS: A comprehensive literature review was conducted using MEDLINE, PubMed, and EMBASE. Databases were screened for papers describing the use of supplements in craniofacial procedures in adult patients using relevant search terms. Data on criteria, outcomes, and patient satisfaction were collected. RESULTS: A total of 19 articles were selected from the 806 identified. Fifteen different supplements or combinations of supplements have been studied for use in facial surgeries. Of these 15 supplements, the following demonstrated potential healing benefits: dry ivy leaf extract, Nazalzem ointment (vitamin A and dexpanthenol), combination nasal sprays (phospholipids, fatty acids, vitamin A, and vitamin E), Saireito pills, topical olive oil, yunnan baiyao, melilotus extract, arnica, and combination arnica and ledum. Arnica is the most commonly studied supplement in a variety of facial operations. CONCLUSIONS: There is ample evidence to support a role for the use of certain dietary supplements to optimize wound healing in craniofacial and facial aesthetic surgery. Controlled diet and use of appropriate supplements may have a synergistic beneficial effect on wound healing following craniofacial surgery. However, there is a need for additional reporting to allow for the creation of stronger guidelines and increased patient screening, reporting, and compliance.
