Enhancing Surgical Approach: Breakthrough Markerless Surface Registration With Augmented Reality for Zygomatic Complex Fracture Surgeries.

Innovative technologies with surgical navigation have been used for enhancing surgical accuracies for zygomaticomaxillary complex (ZMC) fractures and offers advantages in precision, accuracy, effectiveness, predictability, and symmetry improvement. Moreover, augmented reality (AR) navigation technology combines virtual reality, 3-dimensional (3D) reconstruction, and real-time interaction, making it ideal for bone tissue operations. Our study explored the usefulness and clinical efficacy of AR technology in intraoperative guidance for reducing ZMC fractures. We retrospectively studied 35 patients with zygomatic complex fractures, comparing outcomes of AR-guided and conventional methods. Furthermore, the AR system provided real-time visualization and guidance. The evaluation included reduction accuracy using root mean square (RMS) value and symmetry analysis using a mirror image of 3D models. Results demonstrated the feasibility and effectiveness of the AR-guided method in improving outcomes and patient satisfaction. In 35 patients (25 males, 10 females), AR-guided (n = 19) and conventional (n = 16) approaches were compared. Age, sex, and fracture type exhibited no significant differences between groups. No complications occurred, and postoperative RMS error significantly decreased (P < 0.001). The AR group had a lower postoperative RMS error (P = 0.034). Augmented reality-guided surgery improved accuracy and outcomes in zygomatic complex fractures. Real-time visualization enhanced precision during reduction and fixation. This innovative approach promises enhanced surgical accuracy and patient outcomes in craniofacial surgery.

The Effect of Obesity on Surgical Outcomes in General Surgery Patients: A Systematic Review of 1,680,694 patients

The study examined the impact of obesity on general surgery patients, analyzing eleven studies with 1,680,694 patients. Results showed that obesity increases postoperative wound infection risk, blood loss, and recovery times. However, prospective studies found no increase in surgical complications or hospitalization expenses. Obesity may protect against venous thromboembolism and death, but post-operative complications in obese patients undergoing general surgical procedures remain controversial due to metabolic, pharmacologic, and systemic illnesses. Obesity increases surgical duration and SSIs, potentially increasing immediate complications.

Procedure Risk vs Frailty in Outcomes for Elderly Emergency General Surgery Patients: Results of a National Analysis.

The direct association between procedure risk and outcomes in elderly emergency general surgery (EGS) patients has not been analyzed. Studies only highlight the importance of frailty. A comprehensive analysis of relevant risk factors and their association with outcomes in elderly EGS patients is lacking. We hypothesized that procedure risk has a stronger association with relevant outcomes in elderly EGS patients compared to frailty. Elderly patients (age > 65) undergoing emergency general surgery operative procedures were identified in the NSQIP) database (2018 to 2020) and stratified based on the presence of frailty calculated by the Modified 5 Item Frailty Index (mFI-5; mFI 0 Non-Frail, mFI 1-2 Frail, and mFI ≥3 Severely Frail) and based on procedure risk. Multivariable regression models and Receiving Operative Curve (ROC) analysis were used to determine risk factors associated with outcomes. A total of 59,633 elderly EGS patients were classified into non-frail (17,496; 29.3%), frail (39,588; 66.4%), and severely frail (2,549; 4.3%). There were 25,157 patients in the low-risk procedure group and 34,476 in the high-risk group.Frailty and procedure risk were associated with increased mortality, complications, failure to rescue, and readmissions. Differences in outcomes were greater when patients were stratified according to procedure risk compared to frailty stratification alone. Procedure risk had a stronger association with relevant outcomes in elderly EGS patients compared to frailty. Assessing frailty in the elderly EGS patient population without adjusting for the type of procedure or procedure risk ultimately presents an incomplete representation of how frailty impacts patient-related outcomes.

Mitral valve surgery in patients with Marfan syndrome

ObjectiveTo review the pathology of the mitral valve (MV) and long-term outcomes of surgery in patients with Marfan syndrome (MFS). Patients and MethodsFrom 1988 through 2020, 60 patients with MFS had surgery to correct mitral regurgitation (MR): 19 had isolated MV surgery, 32 had combined MV and aortic root surgery, and 9 had MV surgery after aortic root surgery. Follow-up was complete for a median of 16.1 years. ResultsMV pathology was myxomatous degeneration in all patients and of advanced degree in 78.6% with bileaflet prolapse in 65.5%, mitral annulus disjunction in 57.5%, and mitral annulus calcification in 8.2% of patients. The MV was repaired in 47 patients and replaced in 13. Kaplan–Meier estimates of cumulative mortality at 20 years 21.3% for all patients, 6.7% after MV repair, and 57.8% after replacement (P < .001). MV reoperations were performed in 5 patients: 2 after repair and 3 after replacement. The cumulative incidence rate of reoperations on the MV was 3.8% at 10 years and 11.0% at 20 years in the entire cohort. Among 47 patients who had MV repair, moderate MR developed in 11 patients and severe in 2. Both patients with severe MR underwent MV reoperation. The cumulative incidence rate of recurrent moderate or severe MR after MV repair was 20.4% at 10 years, and 36.5% at 20 years. ConclusionsMV repair was associated with better survival than MV replacement, but recurrent MR after repair occurred in approximately one-third of the patients at 20 years after surgery.

Optimizing Patient Outcomes in Orthognathic Surgery: A Proposed Nutritional Protocol for Weight Loss Control and Bone Formation

Objective: The primary objective of this research was to conduct a comprehensive literature review, offering an in-depth examination of the nutritional considerations associated with orthognathic surgery and suggest a perioperative nutritional protocol for enhanced recovery. Methods: To achieve this objective, the authors rigorously examined existing literature while adhering to the guidelines outlined in PRISMA-ScR. The scope of eligible studies encompassed various types, with the exclusion of case reports and reviews. The research applied specific inclusion criteria, concentrating on the nutritional aspects relevant to perioperative and/or postoperative phases of major maxillofacial surgery. Results: A total of 39 articles were identified that met the screening criteria. These articles were then used to generate a discussion and propose a protocol aimed at reducing body weight loss following major maxillofacial surgery and improving bone formation post-osteotomies. Conclusions: While the realm of maxillofacial surgery sees significant advancements in other fields, there exists a noticeable gap in addressing the nutritional status of surgical patients. This oversight can potentially lead to suboptimal postoperative outcomes. Recognizing the pivotal role of nutrition in enhancing surgical results, this paper emphasizes the importance of maintaining optimal nutritional status among orthognathic surgery patients.

Bariatric Surgery Outcomes in Patients with Severe Obesity Compared to Patients with Non-Severe Obesity at A New Institution in The United Arab Emirates.

Background: Bariatric surgery is an effective treatment for weight loss, but a higher body mass index (BMI) may lead to higher postoperative complication rates. This study aims to compare perioperative and postoperative outcomes between UAE patients with severe obesity (SO) [BMI ≥ 50 kg/m2] and non-severe obesity (NSO) [BMI < 50 kg/m2] undergoing primary bariatric surgery. Methods: From September 2015 to July 2019, 542 patients, 94 SO (56.5 ± 6.2 kg/m2) and 448 NSO (41.8 ± 4.1 kg/m2), were retrospectively reviewed. Results: Patients with SO were younger (33.8 ± 13.4 vs. 37.0 ± 11.5 years, p = 0.02) but otherwise had similar demographic characteristics. Their rates of Roux-en-Y gastric bypass (39.4% SO vs. 44.4% NSO, p = 0.37) and sleeve gastrectomy (60.6% vs. 55.6%, p = 0.37) were similar. There were no differences between perioperative complications (6.4% SO vs. 5.8% NSO, p = 0.83), major postoperative complications (5.3% vs. 3.5%, p = 0.42), readmissions (5.3% vs. 3.3%, p = 0.36), or reoperations (3.2% vs. 2.7%, p = 0.78). There were no mortalities. Their total body weight loss was comparable at 12 months (28.1 ± 10.2% vs. 29.0 ± 7.7%, p = 0.58). Conclusions: Although a higher BMI may pose operative challenges, UAE patients with SO do not have worsened outcomes in bariatric surgery, demonstrating similarly low morbidity to patients with NSO, and similar rates of improvement in their BMI.

Effects of mindful breathing training combined with diary-based rehabilitation guidance in lung cancer patients undergoing surgery: A randomized controlled trial

Background and purposeLung cancer surgery patients experience severe physical and mental symptoms, which seriously affect their quality of life and prognosis. Mindful breathing training is a promising strategy to improve their symptoms, but its effectiveness is affected by training compliance, and diary-based rehabilitation instruction has been shown to help improve training compliance. Therefore, the aim of this study was to evaluate the effects of mindful breathing training combined with diary-based rehabilitation guidance on improving perioperative outcomes in lung cancer surgery patients. Materials and methodsThis single-center, assessor-blinded, prospective, three-arm randomized controlled trial was conducted from November 1, 2021 to November 1, 2022. Patients diagnosed with primary non-small cell lung cancer and scheduled for thoracoscopic surgery were randomly allocated to the combined intervention group, the mindful breathing group or the control group, with 34 patients in each group. The control group received routine care, while the mindful breathing group received mindful breathing training and routine care. The combined intervention group received both mindful breathing training and diary-based rehabilitation guidance, along with routine care. ResultsThe per-protocol analysis revealed that patients in the mindful breathing group experienced statistically significant improvements in dyspnea, fatigue and anxiety. Patients in the combined intervention group had statistically significant improvements in dyspnea, fatigue, anxiety, depression, exercise self-efficacy and training compliance. ConclusionThis study provides evidence that mindful breathing training combined with diary-based rehabilitation guidance can be effective in improving perioperative outcomes in lung cancer patients. It can be applied in clinical practice in the future.

O166: Safety and Efficacy of Autologous Fat Grafting in the Treatment of Radiation-Induced Fibrosis and Contour Defects in Head and Neck Reconstruction

Abstract Background Multimodal treatment for head and neck cancer results in significant functional and cosmetic morbidity, often through contour deformity and radiation-induced skin fibrosis (RIF), affecting head and neck function and cosmesis. Autologous fat grafting is an emerging treatment for RIF. We conducted a retrospective cohort review of patient outcomes following autologous fat transfer for reconstruction of head and neck contour deformity and RIF. Methods A retrospective analysis was performed of patients treated at 2 UK centres between 2009-2022. Patient data collated included demographics, oncological treatment, reconstruction, operative details, and pre- and post-operative patient reported outcome measures (PROMs) including University of Washington Quality of Life Questionnaire (UW-QOL), Derriford Appearance Scale (DAS24) and Patient Outcomes of Surgery (POS). Patients were stratified by indication for AFG. Results A total of 45 patients were identified. 89% of patients (85% RIF, 92% contour deformity) reported cosmetic or functional improvement. Two patients (4%) reported no improvement, and three (7%) were lost to follow-up. Psychological health scores improved in patients following AFG for both RIF and contour deformity patients (DAS24, P&amp;lt; 0.0001). The UW-QOL scores revealed statistically significant improvements in multiple functional domains including appearance, activity, recreation, mood, and anxiety in both patients with RIF and contour deformities. Conclusion This study demonstrates that AFG is an effective technique for the correction of contour deformity and RIF in patients following treatment for head and neck cancer. Patients suffering from RIF demonstrated significant improvements in both functional and psychological domains.

Association Of Opioid Prescribing And Consumption With Patient-Reported Experiences And Satisfaction Following Emergency Surgery In Michigan.

To investigate the relationships between opioid prescribing, consumption, and patient reported outcomes (PROs) in emergency surgery patients. Overprescribing of opioids for pain management after surgery has become a public health concern and major contributor to opioid misuse and dependency. Current guidelines do not address opioid prescribing following emergency surgical procedures, highlighting the importance of understanding the relationship between opioid prescribing and consumption in this setting. Retrospective analysis of the quantity of opioids prescribed and patient-reported outcomes (PROs) in a population-based setting. The sample included adults 18 years and older undergoing emergency surgery across 69 hospitals in Michigan. Patients were included if they received a discharge opioid prescription and had valid data for opioid consumption and PROs. Surgical procedures took place between January 1, 2018 and December 31, 2020. During the study period, a total of 3,742 patients underwent an emergency operation. The mean number of opioid pills prescribed was 9.6 and the mean number of opioid pills consumed was 4.6. In a two-model with logit in the first part and a linear regression in the second, prescription size was significantly associated with both the probability of consumption (aOR 1.02, 95% CI 1.01-1.04) and the amount of consumption conditional on any consumption (coefficient 0.70 95% CI 0.54-0.86). Patients only consumed half of the opioids they were prescribed after undergoing emergency surgery. Additionally, patients who were given larger prescriptions consumed more opioids, but did not experience less pain, higher satisfaction, better quality of life, or less regret to undergo surgery. Overall, this suggests that opioids may be excessively prescribed to patients undergoing emergency surgical procedures, and that larger prescriptions do not improve the patient experience after surgery.

Optimizing patient outcome in intracranial tumor surgery: a detailed prospective study of adverse events and mortality reduction strategies in neurosurgery

IntroductionBrain tumor surgery represents a critical and high-risk area within the field of neurosurgery. Our study aims to offer a comprehensive analysis of adverse events (AEs) from a prospectively maintained database at a leading neurosurgical tertiary center, with a specific focus on different types of tumor entities.MethodsFrom January 2022 to September 2023, our study focused on adult patients, who underwent surgery for intracranial tumors. Each patient in this demographic was thoroughly assessed for adverse events (AEs) by their attending physicians at discharge. An AE was defined as any event occurring within the first 30 days post-surgery.ResultsA total of 1173 patients with an average age of 57.4 ± 15.3 years underwent surgical procedures. The majority of these surgeries were elective, accounting for 93.4% (1095 out of 1173), while emergency surgeries constituted 13.9% (163 out of 1173). The incidence of surgery-related AEs was relatively low at 12.7%. The most common surgical indications were meningioma and glioma pathologies, representing 31.1% and 28.2% of cases, respectively. Dural leaks occurred in 1.5% of the cases. Postoperative hemorrhage was a significant complication, especially among glioma patients, with ten experiencing postoperative hemorrhage and eight requiring revision surgery. The overall mortality rate stood at 0.8%, corresponding to five patient deaths. Causes of death included massive postoperative bleeding in one patient, pulmonary embolism in two patients, and tumor progression in two others.ConclusionsSurgical interventions for intracranial neoplasms are inherently associated with a significant risk of adverse events. However, our study’s findings reveal a notably low mortality rate within our patient cohort. This suggests that thorough documentation of AEs, coupled with proactive intervention strategies in neurosurgical practices, can substantially enhance patient outcomes.

The Influence of Preoperative Neurological Complications on Outcomes after Surgery for Infective Endocarditis

Background. Infective endocarditis (IE) is considered a life-threatening cardiac infection with a predilection to involve heart valves. One of the most feared complications of IE is the development of new-onset neurological complications (NCs). The aim of this study is to compare the short- and long-term outcomes of surgery in patients with IE presenting with vs. without NCs. Methods. We retrospectively reviewed patient records which were regularly collected in our institutional database. Between January 2002 and August 2020, 438 consecutive patients who underwent open cardiac surgery in our university hospital due to IE were included in the retrospective study. Results. Of the total cohort, 89 patients (20.3%) had preoperative NCs. Patients in the NC group were more likely to be female (33.7% vs. 23.5%; P=0.049), had more acute kindly injury at presentation (22.5% vs. 10.0%; P=0.002), were more likely to be admitted to ICU (36.0% vs. 18.3%; P&lt;0.001), and had significantly more vegetations (84.3% vs. 69.8%; P=0.006) and overall higher preoperative embolization (92.1% vs. 11.7%; P&lt;0.001). Staphylococcus aureus as causative organism of IE was significantly higher in the NC group (35.2% vs. 16.1%; P&lt;0.001). Patients in the NC group had significantly higher affection of the mitral valve. There was no difference in postoperative outcomes between the two groups. The long-term survival was also similar in both groups. Preoperative atrial fibrillation (adjusted odds ratio (aOR): 2.03; 95% CI [1.04–3.93]; P=0.037) and Staphylococcus aureus IE (aOR: 2.60; 95% CI [1.4–4.8]; P=0.002) were independent risk factors of developing NCs, while previous endocarditis was a protective factor (aOR: 0.33; 95% CI [0.11–0.99]; P=0.048). Conclusion. Our study emphasizes the shared risk factors between mortality and developing NCs. NCs are critical in IE’s clinical presentation, but they do not independently predict short- or long-term survival following surgery for IE.

Erector Spinae Plane Block Placement Utilizing Fluoroscopic Guidance Improves Efficiency in Lumbar Surgery

The erector spinae plane block (ESPB) is a novel regional analgesic technique which improves postoperative outcomes in lumbar surgery patients including length of hospitalization, days to ambulation, and postoperative opioid use. Traditionally, the block is administered by anesthesiologists trained in the ultrasound guidance technique. The use of fluoroscopic guidance may improve the efficiency and accessibility of the ESPB for spine surgeons. We aim to measure the time to administer an ESPB using fluoroscopic guidance and localize the anesthetic using intraoperative three-dimensional (3D) imaging. Two neurosurgeons administered an ESPB to patients undergoing lumbar surgery. Time from insertion of the spinal needle to localize the erector spinae plane using C-arm guidance to time of complete injection and removal of the needle from the skin was recorded. One patient underwent O-arm imaging following injection of an Isovue-Exparel solution at the L3 level to visualize spread of the anesthetic. A total of 21 patients were enrolled in this study. The average duration to perform an ESPB under fluoroscopic guidance was 1.2minutes. The Isovue-Exparel solution was injected at the L3 level and was well distributed along the ESP on intraoperative O-arm imaging. The anesthetic dissected the erector spinae muscle from the transverse process at L2, L3, and L4. Fluoroscopic guidance allows efficient and appropriate delivery of the anesthetic to the erector spinae plane. Performing an ESPB with fluoroscopic guidance improves efficiency and accessibility of the analgesic technique for spine surgeons, reducing dependence on anesthesiology personnel trained in administering the block.

Application of three-dimensional printed biomodels in endoscopic spinal surgery.

Three-dimensional printing (3DP) is increasingly used to individualise surgery and may be an effective tool for representing patient anatomy. Current literature on patient-specific anatomical models (biomodels) for minimally invasive spinal surgery is a limited number of case series and cohort studies. However, studies investigating 3DP in other specialties have reported multiple benefits. This prospective study considered a series of patients (n=33) undergoing elective endoscopic spinal surgery, including combinations of microdiscectomy (n=27), foraminotomy (n=7), and laminectomy (n=3). These surgeries were conducted at vertebral levels ranging from L2/3 to L5/S1. The surgeon then recorded the impact on preoperational planning, intraoperative decision-making and accelerating the learning curve with a qualitative questionnaire. There were benefits to planning in 54.5% of cases (n=18), improved intraoperative decision-making in 60.6% of cases (n=20). These benefits were reported more frequently earlier in the cases, with improvements to learning reported in 60% of the first five cases and not in subsequent cases. The surgeon commented that the biomodels were more useful on. The rates of preoperative and intraoperative benefits are consistent with existing studies, and the early benefit to the learning curve may be suitable for applications to surgical training. Additional research is required to determine the practicality of biomodels and their impact on patient outcomes for endoscopic spinal surgery.

The impact of anxiety and depression on lumbar spine surgical outcomes: a Michigan Spine Surgery Improvement Collaborative study.

The presence of depression and anxiety has been associated with negative outcomes in spine surgery patients. While it seems evident that a history of depression or anxiety can negatively influence outcome, the exact additive effect of both has not been extensively studied in a multicenter trial. The purpose of this study was to investigate the relationship between a patient's history of anxiety and depression and their patient-reported outcomes (PROs) after lumbar surgery. Patients in the Michigan Spine Surgery Improvement Collaborative registry undergoing lumbar spine surgery between July 2016 and December 2021 were grouped into four cohorts: those with a history of anxiety only, those with a history of depression only, those with both, and those with neither. Primary outcomes were achieving the minimal clinically important difference (MCID) for the Patient-Reported Outcomes Measurement Information System Physical Function 4-item Short Form (PROMIS PF), EQ-5D, and numeric rating scale (NRS) back pain and leg pain, and North American Spine Society patient satisfaction. Secondary outcomes included surgical site infection, hospital readmission, and return to the operating room. Multivariate Poisson generalized estimating equation models were used to report incidence rate ratios (IRRs) from patient baseline variables. Of the 45,565 patients identified, 3941 reported a history of anxiety, 5017 reported a history of depression, 9570 reported both, and 27,037 reported neither. Compared with those who reported having neither, patients with both anxiety and depression had lower patient satisfaction at 90 days (p = 0.002) and 1 year (p = 0.021); PROMIS PF MCID at 90 days (p < 0.001), 1 year (p < 0.001), and 2 years (p = 0.006); EQ-5D MCID at 90 days (p < 0.001), 1 year (p < 0.001), and 2 years (p < 0.001); NRS back pain MCID at 90 days (p < 0.001) and 1 year (p < 0.001); and NRS leg pain MCID at 90 days (p < 0.001), 1 year (p = 0.024), and 2 years (p = 0.027). Patients with anxiety only (p < 0.001), depression only (p < 0.001), or both (p < 0.001) were more likely to be readmitted within 90 days. Additionally, patients with anxiety only (p = 0.015) and both anxiety and depression (p = 0.015) had higher rates of surgical site infection. Patients with anxiety only (p = 0.006) and depression only (p = 0.021) also had higher rates of return to the operating room. The authors observed an association between a history of anxiety and depression and negative outcome after lumbar spine surgery. In addition, they found an additive effect of a history of both anxiety and depression with an increased risk of negative outcome when compared with either anxiety or depression alone.

Bariatric Surgery Outcomes in Patients with Inflammatory Bowel Disease in the United States: An Analysis of the Nationwide Readmissions Database

PurposeBariatric surgery has been reported to produce durable weight loss in the management of obesity; sleeve gastrectomy (SG) is the most common bariatric procedure. Obesity is a common comorbidity of inflammatory bowel disease (IBD), and the impact of IBD on short-term SG outcomes has not been widely reported. This study assessed whether IBD was associated with adverse post-SG outcomes.Materials and MethodsHospitalizations of patients undergoing SG in the United States were identified using the 2010–2020 Nationwide Readmissions Database (NRD) and stratified by IBD diagnosis. The SG cohort was propensity-matched based on age, biological sex, body mass index (BMI), comorbid diabetes, hypertension, depression, chronic obstructive pulmonary disease, and discharge in quarter four. Primary aims were to compare in-hospital mortality, post-operative complications, and all-cause 90-day readmission between patients with and without IBD. Secondary outcomes were length of stay (LOS) and total hospital cost.ResultsA total of 2030 hospitalizations were matched. The odds of complication were 48% higher for hospitalizations of patients with IBD (11.1% vs. 7.8%; aOR 1.48, aOR 95% CI 1.10–2.00, p = .009). The most common complication was nausea (4.9% vs. 3.7%, p = .187). No statistically significant difference was observed for all-cause 90-day readmissions, LOS, or hospital cost.ConclusionHospitalizations of patients with IBD who underwent SG experienced significantly higher post-operative complication rates. However, the similar lengths of stay and readmission rates compared to propensity-matched SG hospitalizations without IBD suggest many complications were minor. SG remains a safe weight loss procedure for patients suffering from IBD and obesity.Graphical

Adaptation of a standardized lifestyle intervention to maximize health outcomes in adolescent metabolic and bariatric surgery patients.

Metabolic and bariatric surgery (MBS) is safe and efficacious in treating adolescents with severe obesity. Behavioral/lifestyle programs can support successful preparation for surgery and post-MBS weight loss, but no standardized lifestyle intervention exists for adolescents. Here we describe the process of developing and adapting the Diabetes Prevention Program Group Lifestyle Balance (DPP/GLB) curriculum to support adolescents pre- and post-MBS. We collected both qualitative and quantitative data from a diverse group of adolescents (N = 19, mean age 15.2years, range 13-17, 76% female, 42% non-Hispanic Black, 41% Hispanic, 17% other). Additionally, we included data from 13 parents, all of whom were mothers. These participants were recruited from an adolescent MBS program at Children's Health System of Texas. In an online survey, we asked participants to rank their preferences and interests in DPP/GLB content topics. We complemented these results with in-depth interviews from a subset of 10 participants. This qualitative data triangulation informed the development of the TeenLYFT lifestyle intervention program, designed to support adolescents who were completing MBS and described here. This program was adapted from adolescent and parent DPP/GLB content preferences, incorporating the social cognitive model (SCM) and the socioecological model (SEM) constructs to better cater to the needs of adolescent MBS patients. Adolescents' top 3 ranked areas of content were: (1) steps to adopt better eating habits and healthier foods; (2) healthy ways to cope with stress; and (3) steps to stay motivated and manage self-defeating thoughts. Nearly all adolescent participants preferred online delivery of content (versus in-person). Mothers chose similar topics with the addition of information on eating healthy outside the home. Key themes from the adolescent qualitative interviews included familial support, body image and self-confidence, and comorbidities as key motivating factors in moving forward with MBS. The feedback provided by both adolescents and parents informed the development of TeenLYFT, an online support intervention for adolescent MBS candidates. The adapted program may reinforce healthy behaviors and by involving parents, help create a supportive environment, increasing the likelihood of sustained behavior change. Understanding adolescent/parent needs to support weight management may also help healthcare providers improve long-term health outcomes for this patient population.

Impact of COVID-19 on cardiac surgery outcomes.

This study aimed to assess the impact of COVID-19 infection on cardiac surgery outcomes in patients who contracted COVID-19 peri-operatively or had recently recovered from COVID-19. The study prospectively enrolled 95 patients scheduled for cardiac surgery who had recently recovered from COVID-19. This formed the post-COVID-19 group. The other group consisted of 25 patients who contracted COVID-19 peri-operatively. Patients were followed for all-cause mortality as the primary endpoint and postoperative course complications as the secondary endpoint. Data were compared to a historical cohort of 280 non-COVID-19 patients. The peri-operative COVID-19 group exhibited a significantly higher prevalence of primary outcome all-cause mortality (28%), compared with 4.3% in the controls (p < 0.01), as well as the secondary composite endpoint (stroke, peri-operative myocardial infarction and pneumonia) (52 vs 13.9%, p < 0.01). The post-COVID-19 group had a higher incidence of acute pulmonary embolism (3.2 vs 0%, p < 0.01) and atrial fibrillation (23.4 vs 11.4%, p < 0.01). Patients who contracted COVID-19 peri-operatively had an increased rate of mortality and postoperative complications, while cardiac surgery in the recently recovered COVID-19 group was associated with a higher incidence of pulmonary embolism and atrial fibrillation.
