Opioid prescribing practices in breast oncologic surgery-A retrospective cohort study.

BACKGROUND: In breast oncologic surgery, 75% of patients receive a postoperative opioid prescription at discharge, and 10%-20% will develop persistent opioid use. To inform future institutional guidelines, the objective of this study was to determine baseline opioid prescribing patterns in a single high-volume, referral-based breast center. We hypothesized that opioid prescribing practices varied between procedures and operating surgeons. METHODS: A retrospective analysis of all women undergoing breast cancer surgery between January and December 2019. Opioid prescriptions at discharge were converted to morphine milligram equivalents (MME). The primary outcome of interest was MME prescribed at discharge. Multiple linear regression was used to identify factors independently associated with MME prescribed. RESULTS: 392 patients met inclusion criteria; 68.3% underwent partial mastectomy. Median age was 61 (interquartile range [IQR] 51-70). Median MME prescribed at discharge was 112.5 (IQR 75-150); 83.9% of patients were prescribed co-analgesia. The prescriber was a trainee in 37.7% of cases. 15 patients (3.8%) required opioid renewal. On multivariate analysis, axillary procedure was associated with increased MME (ß = 17, 95% CI 5.5-28 and ß = 32, 95% CI 17-47, for sentinel node and axillary dissection, respectively). However, the factor with the greatest impact on MME was operating surgeon (ß = 72, 95% CI 58-87). Residents prescribed less MME compared to attending surgeons (ß = 11, 95% CI -22; -0.06). CONCLUSION: In a tertiary care center, the operating surgeon had the greatest influence on opioid prescribing practices, and trainees tended to prescribe less MME. These findings support the need for a standardized approach to optimize prescribing and reduce opioid-related harms after oncologic breast surgery.

S110-Opioid-free analgesia after outpatient general surgery: A qualitative study focused on the perspectives of patients and clinicians involved in a pilot trial.

BACKGROUND: Opioid-free analgesia (OFA) may mitigate opioid-related harms after outpatient general surgery; however, the comparative effectiveness of this approach should be assessed in robust randomized controlled trials (RCTs). Undertaking an RCT on OFA raises important practical concerns, including surgeon and patient hesitation regarding pain management without opioids. We conducted a qualitative study to explore patients' and clinicians' perspectives and experiences with a pilot trial focused on OFA after outpatient general surgery. METHODS: Patients undergoing outpatient abdominal and breast procedures were randomized to receive post-discharge opioid analgesia (OA) or OFA. Semi-structured interviews with patients and clinicians involved in the trial were conducted to elicit personal perspectives and experiences. Purposive sampling for maximum variation was used to recruit participants with diverse characteristics. Transcribed interviews were assessed using inductive thematic analysis. RESULTS: Ten patients (5 abdominal, 5 breast) and 10 clinicians (6 surgeons, 2 anesthesiologists, 2 nurses) were interviewed. Five major themes emerged: readiness for trial engagement, pre-trial thoughts about the interventions, postoperative pain experiences, intervention acceptability, and trial refinement. Most patients were open to OFA. Clinicians expressed willingness to prescribe OFA, particularly after less invasive procedures and when using peripheral nerve blocks (PNBs). Concerns were raised regarding the adequacy of pain control and side effects of non-opioid drugs (e.g., NSAID-induced bleeding, kidney injury). Overall, participants were enthusiastic about the trial and recognized its relevance; clinicians praised the study design and organization; and patients valued the use of electronic questionnaires. Suggestions for improvements included preventing potential bias arising from the use of PNBs (i.e., via standardization or stratification) and reducing patient burden (i.e., decreasing postoperative questionnaires). CONCLUSION: Patients and clinicians who participated in a pilot RCT generally accept the clinical equipoise between OA versus OFA after outpatient general surgery and recognize the need for methodologically robust trials to inform evidence-based analgesia prescribing.

Efficacy and Safety of Migraine Surgery: A Systematic Review and Meta-analysis of Outcomes and Complication Rates.

OBJECTIVE: The objectives of this study are to assess the efficacy and safety of peripheral nerve surgery for migraine headaches and to bibliometrically analyze all anatomical studies relevant to migraine surgery. SUMMARY BACKGROUND DATA: Migraines rank as the second leading cause of disability worldwide. Despite the availability of conservative management options, individuals suffer from refractive migraines which are associated with poor quality of life. Migraine surgery, defined as the peripheral nerve decompression/trigger site deactivation, is a relatively novel treatment strategy for refractory migraines. METHODS: EMBASE and the National Library of Medicine (PubMed) were systematically searched for relevant articles according to the PRISMA guidelines. Data was extracted from studies which met the inclusion criteria. Pooled analyses were performed to assess complication rates. Meta-analyses were run using the random effects model for overall effects and within subgroup fixed-effect models were used. RESULTS: A total of 68 studies (38 clinical, 30 anatomical) were included in this review. There was a significant overall reduction in migraine intensity (P < 0.001, SE = 0.22, I2 = 97.9), frequency (P < 0.001, SE = 0.17, I2 = 97.7), duration (P < 0.001, SE = 0.15, I2 = 97), and migraine headache index (MHI, P < 0.001, SE = 0.19, I2 = 97.2) at follow-up. A total of 35 studies reported on migraine improvement (range: 68.3%-100% of participants) and migraine elimination (range: 8.3%-86.5% of participants). 32.1% of participants in the clinical studies reported complications for which the most commonly reported complications being paresthesia and numbness, which was mostly transient, (12.11%) and itching (4.89%). CONCLUSION: This study demonstrates improved migraine outcomes and an overall decrease in MHI as well as strong evidence for the safety profile and complication rate of migraine surgery.

Prehabilitation in adult patients undergoing surgery: an umbrella review of systematic reviews.

BACKGROUND: The certainty that prehabilitation improves postoperative outcomes is not clear. The objective of this umbrella review (i.e. systematic review of systematic reviews) was to synthesise and evaluate evidence for prehabilitation in improving health, experience, or cost outcomes. METHODS: We performed an umbrella review of prehabilitation systematic reviews. MEDLINE, Embase, Cochrane, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Joanna Briggs Institute's database, and Web of Science were searched (inception to October 20, 2020). We included all systematic reviews of elective, adult patients undergoing surgery and exposed to a prehabilitation intervention, where health, experience, or cost outcomes were reported. Evidence certainty was assessed using Grading of Recommendations Assessment, Development and Evaluation. Primary syntheses of any prehabilitation were stratified by surgery type. RESULTS: From 1412 titles, 55 systematic reviews were included. For patients with cancer undergoing surgery who participate in any prehabilitation, moderate certainty evidence supports improvements in functional recovery. Low to very low certainty evidence supports reductions in complications (mixed, cardiovascular, and cancer surgery), non-home discharge (orthopaedic surgery), and length of stay (mixed, cardiovascular, and cancer surgery). There was low to very low certainty evidence that exercise prehabilitation reduces the risk of complications, non-home discharge, and length of stay. There was low to very low certainty evidence that nutritional prehabilitation reduces risk of complications, mortality, and length of stay. CONCLUSIONS: Low certainty evidence suggests that prehabilitation may improve postoperative outcomes. Future low risk of bias, randomised trials, synthesised using recommended standards, are required to inform practice. Optimal patient selection, intervention design, and intervention duration must also be determined.

Impact of the Covid-19 pandemic on rates of emergency department utilization and hospital admission due to general surgery conditions.

BACKGROUND: Recent literature reports a decrease in healthcare-seeking behaviours by adults during the Covid-19 pandemic. Given that emergency general surgery (GS) conditions are often associated with high morbidity and mortality if left untreated, the objective of this study was to describe and quantify the impact of the Covid-19 pandemic on rates of emergency department (ED) utilization and hospital admission due to GS conditions. METHODS: This cohort study involved the analysis of an institutional database and retrospective chart review. We identified adult patients presenting to the ED in a network of three teaching hospitals in Montreal, Canada during the first wave of the Covid-19 pandemic (March13-May13, 2020) and a control pre-pandemic period (March13-May13, 2019). Patients with GS conditions were included in the analysis. ED utilization rates, admission rates and 30-day outcomes were compared between the two periods using multivariate regression analysis. RESULTS: During the pandemic period, 258 patients presented to ED with a GS diagnosis compared to 351 patients pre-pandemically (adjusted rate ratio (aRR) 0.75; p < 0.001). Rate of hospital admission during the pandemic was also significantly lower (aRR = 0.77, p < 0.001). Patients had a significantly shorter ED stay during the pandemic (adjusted mean difference 5.0 h; p < 0.001). Rates of operative management during the pandemic were preserved compared to the pre-pandemic period. There were no differences in 30-day complications (adjusted odds ratio (aOR) 1.46; p = 0.07), ED revisits (aOR 1.10; p = 0.66) and (re)admissions (aOR 1.42; p = 0.22) between the two periods. CONCLUSION: There was a decrease in rates of ED utilization and hospital admissions due to GS conditions during the first wave of the Covid -19 pandemic; however, rates of operative management, complications and healthcare reutilization were unchanged. Although our findings are not generalizable to patients who did not seek healthcare, it was possible to successfully uphold institutional standards of care once patients presented to the ED.

Efficacy and Complications of Mandibular Distraction Osteogenesis for Airway Obstruction in the Robin Sequence Population: A Comprehensive Literature Review.

INTRODUCTION: Mandibular distraction osteogenesis (MDO) is becoming the procedure of choice for patients with Robin Sequence (RS) as it offers superior long-term respiratory outcomes in avoidance of tracheostomy. Lacking, is an analysis of the short- and long-term complications. To that end, we have conducted a comprehensive review focusing on complications of MDO. MATERIALS AND METHODS: A systematic review of primary clinical studies reporting outcomes and complications of MDO in RS patients. Outcomes included tracheostomy avoidance and decannulation rate. Complications included dental trauma, nerve injury, surgical site infection and hardware failure. Complications were stratified according to distractor type (internal versus external) and age (>2 months versus <2months). RESULTS: A total of 49 studies yielded 1209 patients with a mean follow-up of 43.78 months. The tracheostomy avoidance rate was 94% (n = 817/870) and the mortality rate was 0.99% (n = 12/1209). The complication rate was 28.9% (n = 349/1209) with surgical site infections (10.5%) being most common. Dental and nerve injuries occurred in 7.9% and 3.2% of patients, respectively. Hardware replacement occurred in 1.2% of patients. internal distractors had higher rates of dental injury whereas external distractors had higher technical failure rates. There were no differences in complication rates ( P= 0.200), mortality ( P = 0.94) or tracheostomy avoidance ( P = 0.058) between patients >2months or <2months of age. CONCLUSION: Mandibular distraction osteogenesis is highly reliable and effective with a low mortality and high tracheostomy avoidance rate. There are important complications including nerve and dental injuries which require long-term follow-up. Neonatal patients do not appear to be at higher risk of complications reinforcing the safety of MDO in this population.

Tips, Tricks, and Pearls for a Superior Patient and Surgeon Experience for Wide-awake Dupuytren Surgery.

Fasciectomy for Dupuytren disease is a common procedure traditionally performed with a tourniquet under general or regional anesthesia. Since the year 2001, the wide-awake local anesthesia no tourniquet (WALANT) approach has been applied successfully to Dupuytren surgery, with current excellent surgeon and patient satisfaction. However, using WALANT for Dupuytren surgery may be intimidating for hand surgeons who want to begin using this method. The purpose of this article is to offer a series of tips and tricks the authors have learned after having performed hundreds of WALANT fasciectomies, to make this technique easier for surgeons and a more pleasurable experience for patients.

Immediate DIEP Breast Reconstruction in a Trans Woman with Breast Cancer.

Breast cancer is a leading cause of cancer among cisgender women worldwide, with an incidence that continues to rise. Breast reconstruction is increasingly recognized as an integral part of breast cancer management. In tandem, the population of trans women is also increasing. However, few studies have focused on the management of breast cancer in this population, given that estrogen therapy has the potential to increase the risk of breast cancer. We present the case of a 51-year-old trans woman diagnosed with right breast cancer following a 32-year history of estrogen therapy. She presented to our clinic for consultation and immediate breast reconstruction. She opted for bilateral skin-sparing mastectomies, sentinel lymph node biopsies, and immediate breast reconstruction using deep inferior epigastric perforator free flaps. There were no postoperative flap complications. Final pathology revealed invasive mucinous carcinoma, devoid of lymph node involvement. The patient was satisfied with her reconstruction and is currently planning for nipple reconstruction. To the authors' knowledge, this is the first reported case in the literature of bilateral deep inferior epigastric perforator free flap reconstruction in the trans female population after breast cancer diagnosis. This case underscores the need for a holistic treatment approach and heightened vigilance among trans women on estrogen therapy. It also highlights that breast reconstruction should be considered and offered to this patient population.

The Montreal Children's Hospital Experience Managing Robin Sequence: An Analysis of Outcomes and Algorithm for Surgical Technique Selection.

BACKGROUND: The development of mandibular distraction osteogenesis (MDO) and tongue-lip adhesion (TLA) has led to significant improvements in respiratory outcomes for the Robin sequence (RS) population. Despite such advances, there continues to be debate regarding management strategies. The authors present their experience managing the RS population with insights on technique selection. METHODS: A retrospective review of RS patients treated at the senior author's institution from 2003 to 2021 was conducted. Baseline patient demographics and clinical parameters including feeding and respiratory status were recorded. Outcomes included the need for tracheostomy or tracheostomy, decannulation rates, and feeding status. Patients were evaluated through overnight oximetry and drug-induced sleep endoscopy (DISE). Outcomes were stratified according to management technique (MDO, TLA, versus conservative) and compared through statistical analysis. RESULTS: Fifty-nine RS patients were included. Twenty-eight were managed conservatively, 19 underwent MDO, 10 underwent TLA, one underwent both TLA and MDO, and one underwent tracheostomy primarily. Overall, 1.7% of the cohort required a tracheostomy and 86% achieved oral feeding after the procedure. The MDO cohort had lower Apgar scores and mean birth weight compared with the conservative and TLA cohorts ( P < 0.05). There were no statistical differences in respiratory and feeding outcomes across all three cohorts. CONCLUSIONS: A therapeutic algorithm was developed with insight into the use of DISE and risk stratification with overnight oximetry to guide procedural selection. Using this approach, safe and satisfactory respiratory outcomes were achieved with a low tracheostomy rate. Risk stratification is possible without polysomnography, and DISE is a promising tool (that requires further validation) for procedural selection in this population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Outcomes Associated with Moberg and Modified Moberg Flaps in Thumb Reconstruction: A Systematic Review.

Background: Appropriate thumb function is critical as it is makes up approximately 40% of the hand's function leading to the greatest influence in activities of daily living (ADLs). Local flaps are the primary option for thumb reconstruction, of which the Moberg flap has been reported to have the added advantage of its advancement capacity relative to other flaps. This systematic review aims to describe the outcomes of the Moberg advancement flap and its associated modifications for coverage of palmar thumb defects. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed for the conduct of this systematic review. Medline, Embase, CINAHL and Cochrane Library were systematically searched to retrieve relevant citations. Title and abstract as well as full-text assessment were performed in duplicate. Full texts were extracted by one reviewer and data extracted was confirmed by a second. Complication rates and overall means were calculated for the appropriate outcomes. Results: A total of 1,794 citations were retrieved; 15 papers were retained, including 169 patients. The overall mean follow-up was 28.6 months (n = 5 studies). In 136 patients, there was 100% flap viability (n = 12 studies). With regard to thumb aesthetics, 92% (59/64 patients) had favourable outcomes (n = 6 studies). No evidence of postoperative flexion contractures (n = 0/56 patients, 5 studies) was found. Cold intolerance occurred at a rate of 29.8% (n = 17/57, 4 studies) and the infection rate was 10.3% (6/58 patients, 3 studies). Conclusions: Moberg/modified Moberg flaps are a safe option for thumb reconstruction given their associated postoperative outcome and complication profile. Level of Evidence: Level III (Therapeutic).

Immunohistochemical Analysis of Lymphocyte Populations in Acute Skin Rejection: The University Health Network Addition to the Banff Classification.

Acute rejection in vascularized composite allotransplantation has been identified using the Banff 2007 working classification. We propose an addition to this classification based on histological and immunological assessment within the skin and subcutaneous tissue. Methods: Biopsies from vascularized composite transplant patients were obtained at scheduled visits and whenever skin changes occurred. Histology and immunohistochemistry were performed on all samples, looking at infiltrating cells. Results: Observations were made specifically related to each component of the skin, including the epidermis, dermis, vessels, and subcutaneous tissue. Our findings led to the establishment of the University Health Network addition of skin rejection. Conclusions: The high rate of rejection where the skin is involved requires novel techniques for early detection. The University Health Network skin rejection addition can serve as an adjunct to the Banff classification.

Sentinel lymph node biopsy in women over 70: Evaluation of rates of axillary staging and impact on adjuvant therapy in elderly women.

BACKGROUND: The 2016 Society of Surgical Oncology Choosing Wisely guidelines recommended against routine sentinel lymph node biopsy in women ≥70 years old with favorable, early-stage breast cancer, as sentinel lymph node biopsy does not decrease recurrence or mortality in these patients. This study's objective was to evaluate the use of sentinel lymph node biopsy and its effect on management in elderly patients. METHODS: A retrospective analysis of female patients ≥70 years old with stage I-II, clinically node-negative, hormone-receptor positive, HER2-negative disease undergoing upfront breast cancer surgery between 2017 and 2019. Primary outcome was rate of sentinel lymph node biopsy. Secondary outcome was effect of sentinel lymph node biopsy on adjuvant therapy. RESULTS: In total, 142 patients were included. Median age was 76 (interquartile range 73-81), and 71.8% underwent lumpectomy. On final pathology, 57.7% had invasive ductal carcinoma, and median tumor size was 15 mm (interquartile range 10-24.3). A total of 118 patients (83.1%) underwent sentinel lymph node biopsy; of these, 27 (22.9%) were positive for N1mi (7 patients) or N1a disease (20 patients). On multivariate regression analysis, patients undergoing sentinel lymph node biopsy were more likely to be younger (odds ratio 0.87, 95% confidence interval 0.78-0.95). The major risk factor for sentinel lymph node biopsy positivity was lymphovascular invasion (odds ratio 13.4, 95% confidence interval 4.57-40.1). Patients with sentinel lymph node biopsy positivity were more likely to receive local adjuvant radiation therapy (odds ratio 4.66, 95% confidence interval 1.49-16.8) and tended to receive more adjuvant regional radiation therapy (75.0% if sentinel lymph node biopsy positive compared with 15.3% if sentinel lymph node biopsy negative, P < .001). CONCLUSION: Despite the 2016 Choosing Wisely guidelines, more than 80% of patients ≥70 years old underwent sentinel lymph node biopsy at our institution. If sentinel lymph node biopsy was positive, this is associated with over 4-fold higher rates of adjuvant radiation therapy.

Implant-based breast surgery and capsular formation: when, how and why?-a narrative review.

Background and Objective: Implant-based breast surgery is a common procedure for both reconstructive and aesthetic purposes. Breast implants, like any foreign object, trigger the formation of a capsule around them. While generally harmless, the capsule can undergo fibrotic changes leading to capsular contracture, which can negatively impact surgical outcomes and patient well-being. Additionally, rare but serious complications, such as breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) and capsule-associated squamous cell carcinoma, have been reported. This paper aims to review the physiology of capsular formation, identify factors contributing to capsule-related pathologies, and discuss their clinical implications. Methods: A review of relevant literature was conducted by searching databases for articles published between inception and September 2022. The search included but not limited to terms such as "capsular formation" and "capsular contracture". Selected articles were critically analyzed to address the objectives of this review. Key Content and Findings: Capsular formation involves interactions between the implant surface, surrounding tissues, and the immune system. Factors influencing pathological changes in the capsule include genetic predisposition, bacterial contamination, implant characteristics, and surgical techniques. Capsular contracture, characterized by tissue hardening, pain, and implant distortion, remains the most common complication. Rare but life-threatening conditions, such as BIA-ALCL and capsule-associated squamous cell carcinoma, necessitate vigilant monitoring and early detection. Conclusions: Understanding the physiology of capsular formation and its associated pathologies is crucial for healthcare providers involved in implant-based breast surgery. Efforts should focus on minimizing the risk of capsular contracture through improved implant materials, surgical techniques, and infection prevention. The emergence of BIA-ALCL and capsule-associated squamous cell carcinoma underscores the importance of long-term surveillance and prompt diagnosis. Further research is needed to uncover underlying mechanisms and develop preventive measures and treatments for these complications. Enhancing our knowledge and clinical management of capsular formation will lead to safer and more successful outcomes in implant-based breast surgery.

Diagnostic reliability in teledermatology: a systematic review and a meta-analysis.

OBJECTIVES: To compare teledermatology and face-to-face (F2F) agreement in primary diagnoses of dermatological conditions. DESIGN: Systematic review and meta-analysis METHODS: MEDLINE, Embase, Cochrane Library (Wiley), CINAHL and medRxiv were searched between January 2010 and May 2022. Observational studies and randomised clinical trials that reported percentage agreement or kappa concordance for primary diagnoses between teledermatology and F2F physicians were included. Titles, abstracts and full-text articles were screened in duplicate. From 7173 citations, 44 articles were included. A random-effects meta-analysis was conducted to estimate pooled estimates. Primary outcome measures were mean percentage and kappa concordance for assessing diagnostic matches between teledermatology and F2F physicians. Secondary outcome measures included the agreement between teledermatologists, F2F dermatologists, and teledermatology and histopathology results. RESULTS: 44 studies were extracted and reviewed. The pooled agreement rate was 68.9%, and kappa concordance was 0.67. When dermatologists conducted F2F and teledermatology consults, the overall diagnostic agreement was significantly higher at 71% compared with 44% for non-specialists. Kappa concordance was 0.69 for teledermatologist versus specialist and 0.52 for non-specialists. Higher diagnostic agreements were also noted with image acquisition training and digital photography. The agreement rate was 76.4% between teledermatologists, 82.4% between F2F physicians and 55.7% between teledermatology and histopathology. CONCLUSIONS AND RELEVANCE: Teledermatology can be an attractive option particularly in resource-poor settings. Future efforts should be placed on incorporating image acquisition training and access to high-quality imaging technologies. TRIAL REGISTRATION NUMBER: 10.17605/OSF.IO/FJDVG.

Feasibility of Prospectively Comparing Opioid Analgesia With Opioid-Free Analgesia After Outpatient General Surgery: A Pilot Randomized Clinical Trial.

Importance: The overprescription of opioids to surgical patients is recognized as an important factor contributing to the opioid crisis. However, the value of prescribing opioid analgesia (OA) vs opioid-free analgesia (OFA) after postoperative discharge remains uncertain. Objective: To investigate the feasibility of conducting a full-scale randomized clinical trial (RCT) to assess the comparative effectiveness of OA vs OFA after outpatient general surgery. Design, Setting, and Participants: This parallel, 2-group, assessor-blind, pragmatic pilot RCT was conducted from January 29 to September 3, 2020 (last follow-up on October 2, 2020). at 2 university-affiliated hospitals in Montreal, Quebec, Canada. Participants were adult patients (aged ≥18 years) undergoing outpatient abdominal (ie, cholecystectomy, appendectomy, or hernia repair) or breast (ie, partial or total mastectomy) general surgical procedures. Exclusion criteria were contraindications to drugs used in the trial, preoperative opioid use, conditions that could affect assessment of outcomes, and intraoperative or early complications requiring hospitalization. Interventions: Patients were randomized 1:1 to receive OA (around-the-clock nonopioids and opioids for breakthrough pain) or OFA (around-the-clock nonopioids with increasing doses and/or addition of nonopioid medications for breakthrough pain) after postoperative discharge. Main Outcomes and Measures: Main outcomes were a priori RCT feasibility criteria (ie, rates of surgeon agreement, patient eligibility, patient consent, treatment adherence, loss to follow-up, and missing follow-up data). Secondary outcomes included pain intensity and interference, analgesic intake, 30-day unplanned health care use, and adverse events. Between-group comparison of outcomes followed the intention-to-treat principle. Results: A total of 15 surgeons were approached; all (100%; 95% CI, 78%-100%) agreed to have patients recruited and adhered to the study procedures. Rates of patient eligibility and consent were 73% (95% CI, 66%-78%) and 57% (95% CI, 49%-65%), respectively. Seventy-six patients were randomized (39 [51%] to OA and 37 [49%] to OFA) and included in the intention-to-treat analysis (mean [SD] age, 55.5 [14.5] years; 50 [66%] female); 40 (53%) underwent abdominal surgery, and 36 (47%) underwent breast surgery. Seventy-five patients (99%; 95% CI, 93%-100%) adhered to the allocated treatment; 1 patient randomly assigned to OFA received an opioid prescription. Seventeen patients (44%) randomly assigned to OA consumed opioids after discharge. Seventy-three patients (96%; 95% CI, 89%-99%) completed the 30-day follow-up. The rate of missing questionnaires was 37 of 3724 (1%; 95% CI, 0.7%-1.4%). All the a priori RCT feasibility criteria were fulfilled. Conclusions and Relevance: The findings of this pilot RCT support the feasibility of conducting a robust, full-scale RCT to inform evidence-based prescribing of analgesia after outpatient general surgery. Trial Registration: ClinicalTrials.gov Identifier: NCT04254679.

The effect of COVID-19 on medical students' education and wellbeing: a cross-sectional survey.

BACKGROUND: Canadian medical school curriculums have undergone major restructuring during the COVID-19 pandemic. This study's goal was to assess the perceived impact of COVID-19 on medical students' education and wellbeing. METHODS: An online survey was distributed to Canadian medical students. Descriptive analyses and ANOVAs were used to assess changes in mental health, health habits and quality of education during the pandemic. RESULTS: 248 medical students from 13 schools across Canada participated in this study. 74% reported a reduction in the quality of their education since COVID-19. 58% of students found online to be inferior to in-person teaching. 65% of students had more time for wellness and leisure activities, about half of the cohort felt more depressed (48%) and lonelier (52%). Student's overall health habits worsened after the start of the pandemic (F=37.4, p < 0.001). Alcohol drinking, time spent seated, and screen time also increased since the pandemic (p < 0.001). During the pandemic, students with a prior history of depression or anxiety expressed increased depressive symptoms (66% vs. 42%, p =0.003), increased anxiety (69% vs. 41%, p < 0001), worse sleep quality (34% vs. 18%, p = 0.031), and poorer quality of life (55% vs. 65%, p = 0.024) versus those with no prior history. CONCLUSION: Canadian medical student's education and wellbeing has been negatively impacted during the pandemic.

CONTEXTE: Les cursus des facultés de médecine canadiennes ont subi une restructuration majeure pendant la pandémie du COVID-19. L'objectif de cette étude était d'évaluer l'impact perçu de la pandémie sur l'éducation et le bien-être des étudiants en médecine. MÉTHODES: Un sondage en ligne a été distribué aux étudiants en médecine au Canada. Des analyses descriptives ont été effectuées et une analyse de variance a été réalisée pour évaluer le changement de quatre habitudes de santé pendant la pandémie. RÉSULTATS: 248 étudiants en médecine de 13 établissements au Canada ont participé à cette étude. 74% d'entre eux ont signalé une baisse de la qualité de leur enseignement depuis le début de la pandémie. 58% des étudiants ont trouvé que l'enseignement en ligne était inférieur à l'enseignement en présentiel. 65% des étudiants ont déclaré avoir plus de temps à consacrer à leurs loisirs et à des activités en lien avec le bien-être, environ la moitié de la cohorte s'est sentie plus déprimée (48 %) et plus seule (52 %). Les habitudes de santé des étudiants se sont considérablement détériorées à l'arrivée de la pandémie (F=37,4, p < 0,001). La consommation d'alcool, le temps passé assis et le temps passé devant un écran ont également augmenté de manière significative depuis le début de la pandémie (p < 0,001). Pendant la pandémie, les étudiants ayant des antécédents de dépression ou d'anxiété ont présenté des niveaux plus élevés de symptômes liés à ces états (66 % contre 42 %, p = 0,003 pour la dépression et 69 % contre 41 %, p<0001 pour l'anxiété), ils avaient une moins bonne qualité de sommeil (34 % contre 18 %, p = 0,031) et une moins bonne qualité de vie en général (55 % contre 65 %, p = 0,024) que ceux qui n'avaient pas de tels antécédents. CONCLUSION: L'éducation et le bien-être des étudiants en médecine canadiens ont été touchés négativement pendant la pandémie.

Current Advances in Hypertrophic Scar and Keloid Management.

Hypertrophic scars and keloids are caused by excessive tissue response to dermal injury due to local fibroblast proliferation and collagen overproduction. This response occurs because of pathologic wound healing due to dysregulation in the inflammatory, proliferative, and/or remodeling phase. Patients with hypertrophic scars or keloids report reduced quality of life, physical status, and psychological health. Hypertrophic scars or keloids will develop in 30 to 90% of individuals, and despite their prevalence, treatment remains a challenge. Of the treatments currently available for hypertrophic scars and keloids few have been adequately supported by studies with appropriate experimental design. Here, we aim to review the available literature to provide up-to-date information on the etiology, epidemiology, histology, pathophysiology, prevention, and management options available for the treatment of hypertrophic scars and keloids and highlight areas where further research is required.
