BACKGROUND/UNASSIGNED:Sexual health is critical to overall health, yet sexual history taking is challenging. LGBTQ+ patients face additional barriers due to cis/heteronormativity from the medical system. We aimed to develop and pilot test a novel sexual history questionnaire called the Sexual Health Intake (SHI) form for patients of diverse genders and sexualities. METHODS/UNASSIGNED:The SHI comprises four pictogram-based questions about sexual contact at the mouth, anus, vaginal canal, and penis. We enrolled 100 sexually active, English-speaking adults from a gender-affirming surgery clinic and urology clinic from November 2022 to April 2023. All surveys were completed in the office. Patients also answered five feedback questions and 15 questions from the Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction (PROMIS-SexFS) survey as a validated comparator. RESULTS/UNASSIGNED:One hundred patients aged 19-86 years representing an array of racial/ethnic groups, gender identities, and sexuality completed the study. Forms of sexual contact varied widely and included all possible combinations asked by the SHI. Feedback questions were answered favorably in domains of clinical utility, inclusiveness of identity and anatomy, and comprehensiveness of forms of sexual behavior. The SHI captured more positive responses than PROMIS-SexFS in corresponding questions about specific types of sexual activity. The SHI also asks about forms of sexual contact that are not addressed by PROMIS-SexFS, such as penis-to-clitoris. CONCLUSIONS/UNASSIGNED:SHI is an inclusive, patient-directed tool to aid sexual history taking without cisnormative or heteronormative biases. The form was well received by a diverse group of participants and can be considered for use in the clinical setting.

BACKGROUND:The effectiveness of virtual-reality (VR) simulation-based training in cleft surgery has not been tested. The purpose of this study was to evaluate learners' acceptance of VR simulation in airway management of a pediatric patient post-cleft palate repair. METHODS:This VR simulation was developed through collaboration between BioDigital and Smile Train. 26 medical students from a single institution completed 10 min of standardized VR training and 5 min of standardized discussion about airway management post-cleft palate repair. They spent 4-8 min in the VR simulation with guidance from a cleft surgery expert. Participants completed pre- and post-surveys evaluating confidence in using VR as an educational tool, understanding of airway management, and opinions on VR in surgical education. Satisfaction was evaluated using a modified Student Evaluation of Educational Quality questionnaire and scored on a 5-point Likert scale. Wilcoxon signed-rank tests were performed to evaluate responses. RESULTS: < .001). Respondents' opinions on incorporating VR in surgical education started high and did not change significantly post-simulation. Participants were satisfied with VR-based simulation and reported it was stimulating (4.31 ± 0.88), increased interest (3.77 ± 1.21), enhanced learning (4.12 ± 1.05), was clear (4.15 ± 0.97), was effective in teaching (4.08 ± 0.81), and would recommend the simulation (4.2 ± 1.04). CONCLUSION/CONCLUSIONS:VR-based simulation can significantly increase learners' confidence and skills in airway management post-cleft palate repair. Learners find VR to be effective and recommend its incorporation in surgical education.

BACKGROUND/UNASSIGNED:Oncoplastic breast-conserving surgery (OBCS) has demonstrated superior cosmetic outcomes to traditional breast-conserving surgery (BCS) while maintaining oncologic safety. While prior studies have compared OBCS to mastectomy, there is a scarcity of literature on the impact of social determinants of health on outcomes. Furthermore, although traditionally tumors larger than 5 cm and multifocal disease were treated with mastectomy, the literature has now shown OBCS to be safe in treating such disease. As a result, patients with large or multifocal tumors could be eligible for both mastectomy and OBCS, which prompts the need for comparison between the two. Thus, the aim of our study was to compare OBCS and mastectomy with reconstruction using BREAST-Q and oncologic outcome measures, as well as stratify these outcomes based on race, ethnicity, and body mass index (BMI). METHODS/UNASSIGNED:A retrospective chart review was performed for 57 patients treated with OBCS and 204 patients treated with mastectomy with reconstruction from 2015 to 2021. Variables including age, race, ethnicity, BMI, insurance status, surgery type, pathology, recurrence, and complications were recorded. Patient-reported outcomes (PROs) were recorded using BREAST-Q pre- and post-operatively. RESULTS/UNASSIGNED:Despite having a higher BMI (P<0.001), OBCS yielded higher "satisfaction with breast" and "satisfaction with outcome" than mastectomy (P=0.02 and P=0.02, respectively). When stratified by race, there were no statistical differences in the PROs between the two surgeries for Hispanic nor African American patients. OBCS had a significantly lower rate of infection and fewer additional surgeries than mastectomy (P=0.004 and P<0.001, respectively). There were no differences in positive margin rate or recurrence rate between the groups. CONCLUSIONS/UNASSIGNED:In our study, OBCS yielded better PROs than mastectomy while maintaining oncologic safety and resulting in fewer surgeries and complications. These excellent outcomes in a majority non-Caucasian cohort support the utilization of OBCS for underserved, minority populations. Larger studies evaluating PROs in diverse and uninsured groups are needed to reinforce these conclusions.

The energy state of endosteal implants is dependent on the material, manufacturing technique, cleaning procedure, sterilization method, and surgical manipulation. An implant surface carrying a positive charge renders hydrophilic properties, thereby facilitating the absorption of vital plasma proteins crucial for osteogenic interactions. Techniques to control the surface charge involve processes like oxidation, chemical and topographical adjustments as well as the application of nonthermal plasma (NTP) treatment. NTP at atmospheric pressure and at room temperature can induce chemical and/or physical reactions that enhance wettability through surface energy changes. NTP has thus been used to modify the oxide layer of endosteal implants that interface with adjacent tissue cells and proteins. Results have indicated that if applied prior to implantation, NTP strengthens the interaction with surrounding hard tissue structures during the critical phases of early healing, thereby promoting rapid bone formation. Also, during this time period, NTP has been found to result in enhanced biomechanical fixation. As such, the application of NTP may serve as a practical and reliable method to improve healing outcomes. This review aims to provide an in-depth exploration of the parameters to be considered in the application of NTP on endosteal implants. In addition, the short- and long-term effects of NTP on osseointegration are addressed, as well as recent advances in the utilization of NTP in the treatment of periodontal disease.

BACKGROUND & AIMS/OBJECTIVE:Abdominal pain is a major symptom of diseases that are associated with microbial dysbiosis, including irritable bowel syndrome and inflammatory bowel disease. Germ-free mice are more prone to abdominal pain than conventionally housed mice, and reconstitution of the microbiota in germ-free mice reduces abdominal pain sensitivity. However, the mechanisms underlying microbial modulation of pain remain elusive. We hypothesized that disruption of the intestinal microbiota modulates the excitability of peripheral nociceptive neurons. METHODS:In vivo and in vitro assays of visceral sensation were performed on mice treated with the nonabsorbable antibiotic vancomycin (50 μg/mL in drinking water) for 7 days and water-treated control mice. Bacterial dysbiosis was verified by 16s rRNA analysis of stool microbial composition. RESULTS:Treatment of mice with vancomycin led to an increased sensitivity to colonic distension in vivo and in vitro and hyperexcitability of dorsal root ganglion (DRG) neurons in vitro, compared with controls. Interestingly, hyperexcitability of DRG neurons was not restricted to those that innervated the gut, suggesting a widespread effect of gut dysbiosis on peripheral pain circuits. Consistent with this, mice treated with vancomycin were more sensitive than control mice to thermal stimuli applied to hind paws. Incubation of DRG neurons from naive mice in serum from vancomycin-treated mice increased DRG neuron excitability, suggesting that microbial dysbiosis alters circulating mediators that influence nociception. The cysteine protease inhibitor E64 (30 nmol/L) and the protease-activated receptor 2 (PAR-2) antagonist GB-83 (10 μmol/L) each blocked the increase in DRG neuron excitability in response to serum from vancomycin-treated mice, as did the knockout of PAR-2 in NaV1.8-expressing neurons. Stool supernatant, but not colonic supernatant, from mice treated with vancomycin increased DRG neuron excitability via cysteine protease activation of PAR-2. CONCLUSIONS:Together, these data suggest that gut microbial dysbiosis alters pain sensitivity and identify cysteine proteases as a potential mediator of this effect.

BACKGROUND:Pharmacologic agents are often used in the antepartum period, however, studies on their effect on fetal development are limited. Thus, this study aims to examine the effect of commonly prescribed antepartum medications on the development of orofacial clefting. METHODS:Utilizing EPIC Cosmos deidentified data from approximately 180 US institutions was queried. Patients born between January 1, 2013, to January 1, 2023, were included. Eight OC cohorts were identified. Gestational medication use was identified by medications prescribed, provider-administered, or reported use by mothers. Medications used in at least 1 in 10,000 pregnancies were included in this analysis. RESULTS:A total of 12 098 newborns with available maternal pharmacologic data were born with any type of orofacial clefting. Prevalence for all oral clefts, any cleft palate, and any cleft lip were 20.56, 18.10, and 10.60 per 10 000 individuals, respectively. Notable significant exposures include most anticonvulsants, such as lamotrigine (OR1.33, CI 1.10-1.62), and topiramate (OR1.35, CI 1.13-1.62), as well as nearly all SSRIs/SNRIs, including fluoxetine (OR1.34, CI 1.19-1.51), sertraline (OR1.25, CI 1.16-1.34), and citalopram (OR1.28, CI 1.11-1.47). Corticosteroids were also correlated including dexamethasone (OR1.19, CI 1.12-1.27), and betamethasone (OR1.64, CI 1.55-1.73), as were antibiotics, including amoxicillin (OR1.22, CI 1.14-1.30), doxycycline (OR1.29, CI 1.10-1.52), and nitrofuran derivatives (OR1.10, CI 1.03-1.17). CONCLUSION/CONCLUSIONS:New associations between commonly prescribed antepartum medications and orofacial clefting were found. These findings should be confirmed as causality is not assessed in this report. Practitioners should be aware of the potential increased risk associated with these medications.

Debridement is a core component of chronic wound management. Although various debridement methods exist, each carries a unique patient risk level. This article discusses the different normal tissue components that are critical to safe debridement practice, various methods of wound debridement for nurses, and the importance of an interprofessional team and consulting a wound specialist.

Three-dimensional printing (3DP) technology has revolutionized the field of the use of bioceramics for maxillofacial and periodontal applications, offering unprecedented control over the shape, size, and structure of bioceramic implants. In addition, bioceramics have become attractive materials for these applications due to their biocompatibility, biostability, and favorable mechanical properties. However, despite their advantages, bioceramic implants are still associated with inferior biological performance issues after implantation, such as slow osseointegration, inadequate tissue response, and an increased risk of implant failure. To address these challenges, researchers have been developing strategies to improve the biological performance of 3D-printed bioceramic implants. The purpose of this review is to provide an overview of 3DP techniques and strategies for bioceramic materials designed for bone regeneration. The review also addresses the use and incorporation of active biomolecules in 3D-printed bioceramic constructs to stimulate bone regeneration. By controlling the surface roughness and chemical composition of the implant, the construct can be tailored to promote osseointegration and reduce the risk of adverse tissue reactions. Additionally, growth factors, such as bone morphogenic proteins (rhBMP-2) and pharmacologic agent (dipyridamole), can be incorporated to promote the growth of new bone tissue. Incorporating porosity into bioceramic constructs can improve bone tissue formation and the overall biological response of the implant. As such, employing surface modification, combining with other materials, and incorporating the 3DP workflow can lead to better patient healing outcomes.
