RESUMO

BACKGROUND: No robust data are available on the safety of primary bariatric and metabolic surgery (BMS) alone compared to primary BMS combined with other procedures. OBJECTIVES: The objective of this study is to collect a 30-day mortality and morbidity of primary BMS combined with cholecystectomy, ventral hernia repair, or hiatal hernia repair. SETTING: This is as an international, multicenter, prospective, and observational audit of patients undergoing primary BMS combined with one or more additional procedures. METHODS: The audit took place from January 1 to June 30, 2022. A descriptive analysis was conducted. A propensity score matching analysis compared the BLEND study patients with those from the GENEVA cohort to obtain objective evaluation between combined procedures and primary BMS alone. RESULTS: A total of 75 centers submitted data on 1036 patients. Sleeve gastrectomy was the most commonly primary BMS (N = 653, 63%), and hiatal hernia repair was the most commonly concomitant procedure (N = 447, 43.1%). RYGB accounted for the highest percentage (20.6%) of a 30-day morbidity, followed by SG (10.5%). More than one combined procedures had the highest morbidities among all combinations (17.1%). Out of overall 134 complications, 129 (96.2%) were Clavien-Dindo I-III, and 4 were CD V. Patients who underwent a primary bariatric surgery combined with another procedure had a pronounced increase in a 30-day complication rate compared with patients who underwent only BMS (12.7% vs. 7.1%). CONCLUSION: Combining BMS with another procedure increases the risk of complications, but most are minor and require no further treatment. Combined procedures with primary BMS is a viable option to consider in selected patients following multi-disciplinary discussion.

RESUMO

Background: Autologous costal cartilage (ACC) and irradiated homologous costal cartilage (IHCC) are commonly used in septorhinoplasty when there is insufficient septal cartilage for grafting. Objective: To assess the surgical outcomes of patients who underwent septorhinoplasty with either ACC or IHCC as measured by rates of infection, resorption, warping, and revision rate. Methods: A retrospective analysis of patients who underwent rhinoplasty with ACC or IHCC at a single academic institution was performed. Demographic data, surgical details, antibiotic use, and outcomes, including surgical duration, infection, resorption, warping, and revision rate, were analyzed using Fisher's exact test, chi-squared test, and logistic regression. Results: One hundred forty-three patients were identified. The median age was 48 years (interquartile range: 35-57.5) and 62.2% (n = 89) were female, 61 patients (42.7%) underwent ACC, and 82 (57.3%) IHCC. Revision rate in both groups was similar (ACC = 14.8%, IHCC = 14.6%; p = 0.98). There was no difference in infection rate (ACC = 4.9%, IHCC = 3.7%; p = 0.71). Postoperative deformity and nasal obstruction were the most common indications for revision surgery. Surgical time was shorter with IHCC (p < 0.01). Mean follow-up time was 26.5 months (±25) for ACC, and 16 months (±12) for IHCC. Conclusions: ACC and IHCC are similar in terms of effectiveness and safety in septorhinoplasty.

RESUMO

Anticoagulation therapy is critical to avoiding thrombotic events in patients following cranial surgery. Although Aspirin, Plavix, and Aggrastat are used as anticoagulants for this purpose, there is no consensus on which agent is the most effective and safe. In this comparative study, we analyze the current evidence on the efficacy and safety of these three anticoagulants in the context of cranial surgeries. This review focuses on the advantages and disadvantages of each anticoagulant, such as its pharmacokinetics, indications, contraindications, and possible consequences. The outcomes of this study will help physicians choose the best anticoagulant for their patients based on individual patient characteristics and the kind of cranial procedure. Aggrastat's potential to be included as a recommended anticoagulant for cranial procedures warrants further study.

RESUMO

In 2008, the American Board of Surgery required residents to pass a laparoscopic fundamentals examination to sit for the boards. As such, minimally invasive surgery became the newest addition as a requisite skill for surgical trainees. To assist in preparing trainees for future surgery, simulation devices have been integrated into training programs to develop proficiency with laparoscopic and arthroscopic techniques. While effective, one of the biggest obstacles to accessing these devices is the thousands of dollars required for the equipment. Many commercial and do-it-yourself (DIY) iterations of low-cost, portable, laparoscopic simulators have been described to address this. While the price point ranges from 300 to 400 dollars, these DIY simulators primarily utilize webcams, iPhones, and tablet cameras in a fixed position. This presents an inherent limitation in the simulator's accuracy as current laparoscopy surgery utilizes camera motion. This study presents a novel DIY simulator that portrays a more realistic view of the operative field using camera motion and positioning, costing approximately 200 dollars. This proposed simulator uses a Universal Serial Bus (USB) endoscope with interchangeable side mirrors. We inserted an endoscope with built-in light-emitting diode (LED) lights into a seamless stainless tube for the laparoscope and attached it to a computer for configuration. To simulate the abdominal cavity, holes were drilled into a ½ torso hollow mannequin at the standard port locations for laparoscopic cholecystectomy, and rubber grommets were inserted into the drilled holes. Trocars were constructed using cross-linked polyethylene (PEX) tubing and #8 rubber stoppers. By creating a more affordable and easily constructed model, acquiring laparoscopic skills is more accessible. Simulators are becoming an essential part of medical training. Affordable simulators like ours allow trainees to develop their laparoscopic skill set at their own pace and convenience. More research into this can potentially lead to increased exposure to more accurate simulators and facilitate more accessible training for performing minimally invasive surgery in any surgical specialty.

RESUMO

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex, multi-symptom illness characterized by debilitating fatigue and post-exertional malaise (PEM). Numerous studies have reported sex differences at the epidemiological, cellular, and molecular levels between male and female ME/CFS patients. To gain further insight into these sex-dependent changes, we evaluated differential gene expression by RNA-sequencing (RNA-Seq) in 33 ME/CFS patients (20 female, 13 male) and 34 matched healthy controls (20 female and 14 male) before, during, and after an exercise challenge intended to provoke PEM. Our findings revealed that pathways related to immune-cell signaling (including IL-12) and natural killer cell cytotoxicity were activated as a result of exertion in the male ME/CFS cohort, while female ME/CFS patients did not show significant enough changes in gene expression to meet the criteria for the differential expression. Functional analysis during recovery from an exercise challenge showed that male ME/CFS patients had distinct changes in the regulation of specific cytokine signals (including IL-1ß). Meanwhile, female ME/CFS patients had significant alterations in gene networks related to cell stress, response to herpes viruses, and NF-κß signaling. The functional pathways and differentially expressed genes highlighted in this pilot project provide insight into the sex-specific pathophysiology of ME/CFS.

RESUMO

The most common etiology of low back and neck pain is associated with spinal cord pathologies. Regardless of origin, low back and neck pain are some of the most common causes of disability worldwide. Mechanical compression due to spinal cord diseases, such as degenerative disc disorders, can lead to radiculopathy, which manifests as numbness or tingling and can progress to loss of muscle function. Conservative management, such as physical therapy, has not been proven effective in treating radiculopathy, and surgical treatments have more risks than benefits for most patients. Epidural disease-modifying medications, such as Etanercept, have been recently explored due to their minimal invasiveness and direct effects on inhibiting tumor necrosis factor-α (TNF-α). Therefore, this literature review aims to evaluate epidural Etanercept's effect on radiculopathy caused by degenerative disc diseases. Epidural Etanercept has been shown to improve radiculopathy in patients with lumbar disc degeneration, spinal stenosis, and sciatica. Further research is needed to compare the effectiveness of Etanercept with commonly used treatments such as steroids and analgesia.

RESUMO

Strokes are the second leading cause of death and disability worldwide. The brain injury resulting from stroke produces a persistent neuroinflammatory response in the brain, resulting in a spectrum of neurologic dysfunction affecting stroke survivors chronically, also known as post-stroke pain. Excess production of tumor necrosis factor alpha (TNF alpha) in the cerebrospinal fluid (CSF) of stroke survivors has been implicated in post-stroke pain. Therefore, this literature review aims to assess and review the role of perispinal etanercept in the management of post-stroke pain. Several studies have shown statistically significant evidence that etanercept, a TNF alpha inhibitor, can reduce symptoms present in post-stroke syndrome by targeting the excess TNF alpha produced in the CSF. Studies have also shown improvements in not only post-stroke pain but also in traumatic brain injury and dementia. Further research is needed to explore the effects of TNF alpha on stroke prognosis and determine the optimal frequency and duration of etanercept treatment for post-stroke pain.

RESUMO

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic, complex multi-organ illness characterized by unexplained debilitating fatigue and post-exertional malaise (PEM), which is defined as a worsening of symptoms following even minor physical or mental exertion. Our study aimed to evaluate transcriptomic changes in ME/CFS female patients undergoing an exercise challenge intended to precipitate PEM. Our time points (baseline before exercise challenge, the point of maximal exertion, and after an exercise challenge) allowed for the exploration of the transcriptomic response to exercise and recovery in female patients with ME/CFS, as compared to healthy controls (HCs). Under maximal exertion, ME/CFS patients did not show significant changes in gene expression, while HCs demonstrated altered functional gene networks related to signaling and integral functions of their immune cells. During the recovery period (commonly during onset of PEM), female ME/CFS patients showed dysregulated immune signaling pathways and dysfunctional cellular responses to stress. The unique functional pathways identified provide a foundation for future research efforts into the disease, as well as for potential targeted treatment options.

RESUMO

Background: The Michigan Opioid Laws are legislation enacted between 2017 and 2018 as a strategy to combat the growing opioid crisis. Objective: To compare opioid prescription rates and morphine milligram equivalents (MMEs) of opioid prescribed to patients undergoing various facial plastic and reconstructive surgery (FPRS) procedures before, during, and after legislation enactment. Materials and Methods: This is a cross-sectional retrospective review of subjects undergoing any of 10 FPRS procedures between July 2016 and November 2019 at a tertiary care hospital with analysis of demographic factors, opioid prescription rates, and MMEs over time. Results: Of 863 patients included, 107 and 575 patients were prescribed postoperative opioids before and after opiate legislation enactment, respectively, with no difference in baseline demographics between groups. Regression analysis showed no change in MME prescribing in the year before legislation (p = 0.70), followed by a decrease of 0.13 MME per day (p = 0.00), with a subsequent stabilization of MME at a reduced rate for the remainder of the study period (p = 0.74). Conclusion: Enactment of the Michigan Opioid Laws was temporally associated with a decrease in opioid prescriptions for common facial plastic surgery procedures.

RESUMO

BACKGROUND: Adoptive transfer of natural killer (NK) cells with augmented antibody-dependent cellular cytotoxicity (ADCC) capabilities and resistance to CD38 targeting has the potential to enhance the clinical anti-myeloma activity of daratumumab (DARA). Therefore, we sought to develop an efficient CRISPR/Cas9-based gene editing platform to disrupt CD38 expression (CD38 knockout (KO)) in ex vivo expanded NK cells and simultaneously arm CD38KO NK cells with a high-affinity CD16 (CD16-158V) receptor. METHODS: CD38KO human NK cells were generated using Cas9 ribonucleoprotein complexes. The platform was expanded by incorporating messenger RNA (mRNA) transfection of CD38KO NK cells and targeted gene insertion at the CD38 locus to mediate gene knockin (KI). The capacity of these gene-edited NK cells to persist and mediate ADCC in the presence of DARA was tested in vitro and in a MM.1S xenograft mouse model. RESULTS: Highly efficient CD38 gene disruption was achieved in ex vivo expanded NK cells without affecting their proliferative or functional capacity. CD38 KO conferred resistance to DARA-induced NK cell fratricide, enabling persistence and augmented ADCC against myeloma cell lines in the presence of DARA in vitro and in a MM.1S xenograft mouse model. CD38KO NK cells could be further modified by transfection with mRNA encoding a CD16-158V receptor, resulting in augmented DARA-mediated ADCC. Finally, we observed that a homology-directed repair template targeted to the CD38 locus facilitated an efficient 2-in-1 CD38 KO coupled with KI of a truncated CD34 reporter and CD16-158V receptor, with CD38KO/CD16KI NK cells demonstrating a further enhancement of DARA-mediated ADCC both in vitro and in vivo. CONCLUSIONS: Adoptive immunotherapy using ex vivo expanded CD38KO/CD16KI NK cells has the potential to boost the clinical efficacy of DARA. By incorporating complementary genetic engineering strategies into a CD38 KO manufacturing platform, we generated NK cells with substantially augmented CD38-directed antitumor activity, establishing a strong rationale for exploring this immunotherapy strategy in the clinic.

RESUMO

BACKGROUND: Machine learning (ML) is increasingly used to predict suicide deaths but their value for suicide prevention has not been established. Our first objective was to identify risk and protective factors in a general population. Our second objective was to identify factors indicating imminent suicide risk. METHODS: We used survival and ML models to identify lifetime predictors using the Cohort of Norway (n=173,275) and hospital diagnoses in a Saskatoon clinical sample (n=12,614). The mean follow-up times were 17 years and 3 years for the Cohort of Norway and Saskatoon respectively. People in the clinical sample had a longitudinal record of hospital visits grouped in six-month intervals. We developed models in a training set and these models predicted survival probabilities in held-out test data. RESULTS: In the general population, we found that a higher proportion of low-income residents in a county, mood symptoms, and daily smoking increased the risk of dying from suicide in both genders. In the clinical sample, the only predictors identified were male gender and older age. CONCLUSION: Suicide prevention probably requires individual actions with governmental incentives. The prediction of imminent suicide remains highly challenging, but machine learning can identify early prevention targets.

RESUMO

Importance: Understanding whether statewide legislation, such as the Michigan Opioid Laws, is associated with reduction in postoperative opioid prescriptions is informative in guiding future legislation. Objective: To identify changes in opioid prescribing patterns for oculoplastic and orbital procedures associated with the enactment of the Michigan Opioid Laws in 2017 and 2018. Design, Setting, and Participants: This cross-sectional study included 3781 patients who underwent any of 10 common oculoplastic and orbital procedures between June 1, 2016, and November 30, 2019, at a tertiary care institution. Exposures: From 2017 to 2018, Michigan enacted a series of laws to address the state's worsening opioid epidemic. Two major components of this legislation enacted on June 1, 2018, required prescribers to review a report of patients' opioid use history and obtain signed consent after educating patients on the use and disposal of opioids prior to prescribing. Main Outcomes and Measures: Demographic information, type of surgery, type and amount of opioid prescriptions, and morphine milligram equivalent (MME) were analyzed. MME was calculated as the product of dose, quantity, and opioid-specific conversion factor for each prescription. Linear interpolation spline regression was used to evaluate the association of prescription MME with time. Results: Of 3781 patients, 1614 (42.7%) were male. The mean (SD) age at the time of surgery was 63.3 (16.6) years. Of 2026 patients undergoing surgery before June 1, 2018, 1782 (88.0%) were prescribed postoperative opioids; of 1755 patients undergoing surgery after June 1, 2018, 878 (50.0%) were prescribed postoperative opioids (P < .001). There was no difference in age, sex, race/ethnicity, surgery type, or opioids prescribed between these 2 cohorts. Linear interpolation spline regression showed a decrease of 26.025 MMEs (equivalent to a 36.2% reduction of mean MME) between June 1, 2017, and September 30, 2018 (ß, -1.735; 95% CI, -0.088 to -0.024; P < .001), stabilizing at a persistently reduced rate of MME prescribed through the end of the study period (October 1, 2018, to November 30, 2019; ß, -0.005; 95% CI, -0.039 to 0.016; P = .42). Changes in MME in the 12 months before or 12 months after the period of legislation enactment were not identified. Conclusions and Relevance: In this cross-sectional study, reduction in opioid prescriptions for oculoplastic and orbital procedures was observed during the enactment period of the Michigan Opioid Laws and appeared to be sustained through the end of the study period. Similar statewide or national legislations aimed at increasing prescriber awareness and patient education on opioid use may help curtail the prescription opioid epidemic.

RESUMO

Health-related quality of life (HRQOL) is an important measure of patient experience before, during, and after treatment for skin cancers. Over the past 20 years, a variety of generic as well as disease-specific HRQOL instruments have been developed to assess clinical outcomes. Clinical trials have increasingly focused on using HRQOL instruments as outcome measures. Patients with both cutaneous melanoma and nonmelanotic skin cancers have been found to experience improvement in HRQOL following surgical treatment and reconstruction. Individual demographic variables may further predict experience within each of these groups. Increasing use of HRQOL instruments in future studies comparing skin cancer treatments will allow physicians to better understand and optimize patient experiences.

RESUMO

Facial reconstruction may be effectively performed in an office setting using a variety of techniques. Careful patient selection is paramount for achieving successful outcomes in this setting. The most common reconstructive techniques used in the office setting include local flaps and skin grafts. Scar management is complementary to all facial reconstructive procedures, and the reconstructive surgeon has a large variety of scar management techniques available. Scar management should be individualized based on clinical setting and available resources.

RESUMO

IMPORTANCE: Contingent valuation, or willingness to pay, is an established economic concept that has been applied in other areas of medicine and may be useful for understanding the economic forces that determine the cost of cosmetic procedures. OBJECTIVE: To determine the monetary value of changes in attractiveness achieved through rhinoplasty, as perceived by society. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional survey administered via public online forums to 228 casual observers. MAIN OUTCOMES AND MEASURES: Participants were shown preoperative and postoperative photographs of 12 patients who underwent cosmetic rhinoplasty and 4 patients who did not undergo any surgery. They were asked to rate (1) the change in overall attractiveness of the patients, and (2) the monetary value they would associate with these changes. RESULTS: Completed surveys were obtained from 228 casual observers; 144 were female (63.2%); median age, 25 years (median income bracket, $50 000-$75 000). Multilevel, mixed-effects, linear regression was used to characterize the association between monetary value and change in attractiveness. There was a significant association between the change in attractiveness from a rhinoplasty and its monetary value as perceived by society. The baseline value of a rhinoplasty without any change in attractiveness was $3769.98 (95% CI, $3541.59-$4007.10; P < .001). To increase 1 standard deviation in attractiveness was worth an additional $2353.77 (95% CI, $2197.57-$2512.81; P < .001), while increasing 2 standard deviations in attractiveness was worth an additional $5453.07 (95% CI, $5052.57-$5865.51; P < .001). CONCLUSIONS AND RELEVANCE: There is a significant association between the societally perceived value of cosmetic rhinoplasty and the change in attractiveness after surgery. The average value of a rhinoplasty in our study approximates the actual average cost of cosmetic rhinoplasty, suggesting that willingness to pay may be a useful concept for studying the value of cosmetic procedures. LEVEL OF EVIDENCE: NA.

RESUMO

Nasal reconstructive techniques have advanced significantly over the past 50 years. Modern techniques in nasal reconstruction are based on the nasal aesthetic subunits. In order to achieve ideal outcomes, reconstructive surgeons must consider differences in tissue qualities across the nasal aesthetic subunits and formulate reconstructive plans based on these differences. Local flaps, skin grafts, and several types of interpolated flaps comprise the most commonly used techniques for nasal reconstruction. Defects that involve structural or internal lining defects require reconstruction of significantly higher complexity.

RESUMO

Flaccid facial paralysis results in disfiguring facial changes. The treatment of flaccid facial paralysis is complex and treatment approaches should be determined based on duration and the causes of paralysis, status and accessibility of the affected facial nerve, medical comorbidities, and patient-specific goals. Although primary nerve repair is the preferred treatment strategy when possible, nerve substitution procedures are the mainstay of treatment for patients with flaccid facial paralysis of less than 2 years duration.

RESUMO

IMPORTANCE: Blepharoplasty consistently ranks among the most common facial plastic surgery procedure sought by both men and women. Despite the popularity of blepharoplasty, there has been little research focused on quantifying how eyelid surgery changes facial perceptions. OBJECTIVES: To quantify the effect of blepharoplasty on facial perceptions and measure patient-reported ratings of fatigue before and after surgery to compare observer and patient perceptions. DESIGN, SETTING, AND PARTICIPANTS: A web-based survey experiment was conducted from January to February 2017, featuring photographs of female patients before and after blepharoplasty. Observers were randomly shown independent images of each patient and asked to rate perceived age, attractiveness, health, and energy level. Respondents saw only preoperative or postoperative photographs of each patient to reduce bias due to priming. Patient-reported outcomes were also collected. MAIN OUTCOMES AND MEASURES: A multivariate mixed effects regression model was used to quantify the changes in each domain after surgery. Ordinal rank change was calculated to provide a measure of clinical effect size across the domains. To analyze patient-reported outcomes, a Kruskal-Wallis test followed by Mann-Whitney tests were performed to determine if there were differences in patient-perceived tiredness based on operative status. RESULTS: A total of 401 participants (243 women, 152 men, and 6 not specified; mean age 25.9 years [range, 18-73 years]) successfully completed the survey and evaluated before-and-after photographs of 10 female patients (mean age, 59.8 years). The multivariable mixed effects model revealed that individuals are perceived as appearing significantly younger (-1.04 years; 95% CI, -1.70 to -0.37 years) and more attractive (coefficient, 4.92; 95% CI, 3.91-5.93) after blepharoplasty. Ratings of perceived health (coefficient, 4.33; 95% CI, 3.28-5.37) and energy level (coefficient, 9.83; 95% CI, 8.51-11.16) also improved significantly. After undergoing blepharoplasty, patients had significantly improved ratings of energy level compared with those who had not undergone blepharoplasty. CONCLUSIONS AND RELEVANCE: This is the first study, to date, aimed at quantifying the perceptions of facial aesthetic changes following blepharoplasty. The data demonstrate that individuals are rated as appearing more youthful, attractive, and healthy following blepharoplasty. Furthermore, both patients and casual observers perceived a significant improvement in energy level following blepharoplasty, a meaningful finding as the appearance of fatigue is a chief concern of the patients before they undergo blepharoplasty. LEVEL OF EVIDENCE: NA.

RESUMO

IMPORTANCE: Ehlers-Danlos syndromes (EDSs) are a group of heritable connective tissue disorders. Patients with EDSs can develop excessive facial rhytids, nasal deformities, and facial scarring, for which they may seek consultation with a facial plastic surgeon. Ehlers-Danlos syndromes can be associated with serious surgical complications and should be identified preoperatively to facilitate optimal treatment. To our knowledge, no management guidelines for patients with EDSs exist in the facial plastic surgery literature. We present a review of the literature and management recommendations for the facial plastic surgeon. OBSERVATIONS: We performed a PubMed/MEDLINE search for all publications in the English language related to surgical experience in patients with EDSs. A total of 37 publications (including reviews and case series) were included. Ehlers-Danlos syndromes are more common than appreciated, with an overall point prevalence between 1 in 2500 and 1 in 5000 according to existing literature. There are 6 main subtypes of EDSs that have significant phenotypic heterogeneity. Patients with classic type and hypermobile EDS (the 2 most common subtypes) can typically undergo elective facial plastic surgery without major complications. However, specific preoperative, intraoperative, and postoperative issues, as outlined in this review, must be taken into consideration. Vascular EDS should serve as a contraindication to elective surgery given its potential for life-threatening complications. CONCLUSIONS AND RELEVANCE: Because of their skin laxity, patients with EDSs may present more frequently to facial plastic surgeons' offices. Simple screening questions can help the surgeon identify potential patients with EDSs. Treatment should be individualized and performed with extreme care to ensure optimal outcomes.
