Conclusion These efforts will enhance the shared values and ethics of our field and improve the quality and validity of our research findings moving forward.

Human papillomavirus (HPV) infection and related cancers are a major cause of morbidity and mortality worldwide. Routine vaccination against HPV is recommended for patients starting at age 9-12 years. Discussing this vaccine with parents of young children can be challenging for clinicians. Barriers include parental beliefs, strength and quality of clinician recommendations, physician knowledge of HPV disease and vaccines, and provider comfort levels with discussing sexuality.

Our interactive workshop began with a predidactic role-play session addressing common concerns about the HPV vaccine where participants took turns playing a concerned parent or provider. We then gave a 30-minute didactic lecture and conducted a postdidactic role-play session to practice communication skills in promoting the HPV vaccine. All participants completed pre- and postintervention knowledge and skill self-assessments.

Twenty-eight pediatric residents and medical students participated. We observed significant improvement in s' skills in discussing the HPV vaccine with parents.

Despite increasing emphasis on LGBTQ health in medical education, evidence-based training on LGBTQ patient care in dermatology is lacking. We designed an interactive online didactic session on dermatologic care of LGBTQ patients for medical students and dermatology residents.

Session content was based on continuing medical education articles and incorporated preexisting LGBTQ-inclusive policies, environments, and videos. We implemented the session via a web-based videoconferencing platform as part of a preexisting resident lecture series. We began with a 90-minute lecture on LGBTQ health care disparities and dermatologists' roles, best practices for providing inclusive care, and dermatologic health concerns and screening recommendations in LGBTQ populations. To solidify knowledge and promote practice of learned skills, a 30-minute interactive role-playing session followed where participants acted as observer, patient, or provider in three distinct clinical scenarios pertaining to dermatologic care of LGBTBTQ patients.

Medical students frequently report lack of confidence and skill in managing ill pediatric patients. We aimed to implement targeted learning interventions to address these knowledge gaps, specifically focusing on pediatric sepsis. Our objective was to create a curriculum to advance knowledge and confidence in identifying and managing pediatric sepsis.

We designed this curriculum to augment medical student pediatric ICU (PICU) and neonatal ICU (NICU) rotations. We first emailed students a pretest and upon completion, we emailed students a series of brief educational videos. Students then participated in a simulation experience designed to assess their ability to diagnose and manage severe sepsis. We provided immediate debriefing after each session. Upon completion of the simulation experience, we emailed students a posttest (identical to the pretest). The pre-/posttest included multiple-choice questions to assess the students' ability to recognize and manage pediatric sepsis and septic shock, as well as Likert-scale questions assessing confidence levels in diagnosis and management of pediatric sepsis. We performed paired Student

tests comparing knowledge-based question scores and Likert-scale results.

Of students, 40 enrolled in and 30 completed the curriculum between 2015 and 2020. When comparing pre- and posttest results, we found a significant improvement in knowledge scores (33% mean increase, 95% CI [22%-45%],

< .001) and confidence levels (mean increase in Likert scale score of 1.5, 95% CI [1.2-1.7],

< .001).

Results suggested that the curriculum advanced students' knowledge scores and improved self-reported confidence in managing theoretical pediatric patients with sepsis.

Inferior alveolar nerve (IAN) injury is one of the most serious complications after extraction of impacted lower third molars. Photobiomodulation (PBM) therapy has been noted to reduce pain and inflammation while promoting tissue healing. This study examined the efficacy of PBM therapy tested in a case series of patients with postoperative IAN injury.

20 patients with post-extraction IAN injury were involved in this study and divided into two groups. In the study group, PBM therapy (808-nm laser, 16 mW, 3 J/cm

) was used every other day for 2 weeks solely on post-extraction sockets in 10 patients diagnosed with IAN injury. Angiogenesis inhibitor In the control group, mecobalamine was prescribed to 10 patients with IAN injury. Objective and subjective recovery of IAN paresthesia was evaluated using clinical neurosensory testing and visual analog score.

All patients showed improvement in both objective and subjective examination. Notably, the visual analog score was significantly improved after PBM treatment compared to the mecobalamine treatment (

< 0.05).

PBM therapy with 808-nm laser appears to be an effective approach to manage paresthesia post-IAN injury following impacted third molar surgery. Given the limited sample size in this study, large-scale, placebo-controlled, multi-center randomized controlled trials are needed for further validation of this innovative treatment.

The formation, accumulation and diffusion of pollution particles occurs under complex temporal scales and expands throughout a wide spatial coverage. Seeking to understand the transport patterns of haze pollutants in China, we review a proposed framework of time-evolving directed and weighted air quality correlation networks. In this work, we evaluate monitoring stations' time-series data from China and California, to test the sensitivity of the framework to region size, climate and pollution magnitude across multiple years (2014-2020). We learn that the use of hourly PM 2.5 concentration data is needed to detect periodicities in the positive and negative correlations of the concentrations. In addition, we show that the standardization of the correlation function method is required to obtain networks with more meaningful links when evaluating the dispersion of a severe haze event at the North China Plain or a wildfire event in California during December 2017. Post COVID-19 outbreak in China, we observe a significant drop in the magnitude of the assigned weights, indicating the improved air quality and the slowed transport of PM 2.5 due to the lockdown. To identify regions where pollution transport is persistent, we extend the framework, partitioning the dynamic networks and reducing the networks' complexity through node subsampling. The end result separates the temporal series of PM 2.5 in set of regions that are similarly affected through the year.The pandemic caused by SARS-CoV-2 virus, also known as COVID-19, has generated shockwaves in medical and surgical practice. It has necessitated re-deployment of staff and resources to cater for the unpredictable increase in footfall and demand on healthcare systems. This study aimed to investigate how the restructuring of our service altered the triage and management of non-melanoma skin cancer (NMSC) during the pandemic's first wave rise and peak. We retrospectively analysed all patients who underwent a skin excision under local anaesthetic which revealed the presence of a basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) on histopathological analysis between 1st February 2020 - 31st May 2020 compared with the same period in 2019. There was a 158% increase in patients with excision of lesions confirmed on histopathological analysis as a NMSC during the COVID-19 period (168 vs. 65). In 2020, more excisions were performed by consultants (42.9% v 21.5%, p = 0.002) with a lower proportion of excisions with a close margin (27.7% v 17.8%, p = 0.096) and an involved margin (3.1% v 1.8%, p = 0.62). Five of these patients had their further management altered due to service constraints at this time The resource constraints secondary to the pandemic have yielded beneficial service adaptations with the incorporation of a more efficient model for the NMSC service. The sustainability of this model and its impact on training will require further examination when non-urgent and benign elective workload is slowly reinstated and plastic surgery trainees return to their original posts.Aerosol particles can spread respiratory infections, especially those caused by viruses; however, the perceived threat is small for many technical reasons, as identified in this article. Under controlled conditions, aerosol particles can travel up to a distance of 28 feet (or 8 m); however, such aerosol particles are less likely to have sufficient quantities of viable viruses to spread infection. Additionally, nearly all the experimental models examined the behavior of the aerosols only in confined spaces, not in open areas; these findings, therefore, cannot be considered generally applicable. In the absence of scientific information and education, only misconceptions, unfounded fears, and unsubstantiated myths will prevail. Given that an effective vaccine and drugs are still not available, prevention remains the only option of protection against SARS-CoV-2, the new coronavirus. Wearing a mask is not only necessary but also critical to reduce the probability of viral spread by contact (fomite), not aerosol, transmission.Robots are being increasingly used in the fight against highly-infectious diseases such as Ebola, MERS, and SARS-COV-2. Many of the robots that are being used employ ultraviolet lights mounted on a mobile base to inactivate the pathogens. However, these lights are often mounted in a fixed configuration and do not provide adequate decontamination of horizontal surfaces, which can be a major source of cross-contamination. In the paper, we describe the design, implementation, and testing of an Ultraviolet Germicidal Irradiation (UVGI) system implemented on a mobile manipulation robot. A human supervisor designates a surface for disinfection, the robot autonomously plans and executes an end-effector trajectory to disinfect the surface to the required certainty, and then displays the results for the human supervisor to verify. We also provide some background information on UVGI and describe how we constructed and validated mathematical models of Ultraviolet (UV) radiation propagation and accumulation. Finally, we describe our implementation on a Fetch mobile manipulation platform, and discuss how the practicalities of implementation on a real robot affect our models.
