Perioperative outcomes of laparoscopic sacrocolpopexy with and without hysterectomy: a secondary analysis of the National Surgical Quality Improvement Program Database.

INTRODUCTION AND HYPOTHESIS: The objective was to compare 30-day perioperative complications in women undergoing minimally invasive sacrocolpopexy with and without a concomitant hysterectomy. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database, we identified women undergoing minimally invasive sacrocolpopexy between 2014 and 2018. Women were then stratified into two groups: sacrocolpopexy only and sacrocolpopexy + hysterectomy. The primary outcome was the occurrence of any 30-day postoperative complication. Group comparisons were performed using Student's t test, Mann-Whitney U test, and Chi-squared test. Multivariate logistic regression was used to identify independent factors associated with the occurrence of any complication. RESULTS: A total of 8,553 women underwent laparoscopic sacrocolpopexy, 5,123 (59.9%) of whom had a concomitant hysterectomy. Median operative time was longer in women who had sacrocolpopexy + hysterectomy compared with sacrocolpopexy alone (185 [129-241] versus 172 [130-224] min, p < 0.001). The rate of any 30-day postoperative complication did not differ between groups (sacrocolpopexy + hysterectomy 5.5% versus sacrocolpopexy alone 5.8%, p = 0.34). Likewise, organ space, deep, and superficial surgical site infections did not differ between groups. There was also no difference in reoperation or readmission rates between groups. On multivariate logistic regression, sacrocolpopexy + hysterectomy were not associated with increased odds of 30-day postoperative complications relative to women who underwent sacrocolpopexy alone. CONCLUSIONS: Complication rates during the first 30 days after minimally invasive sacrocolpopexy are low and concomitant hysterectomy is not associated with increased risks of 30-day complications after surgery.

Mesh complications after total vs supracervical laparoscopic hysterectomy at time of minimally invasive sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: Our objective was to compare mesh exposure rates (4 months and 1 year) after total (TLH) vs supracervical (SLH) laparoscopic hysterectomy at time of minimally invasive sacrocolpopexy (SCP). Secondary outcomes included 30-day complications and midurethral mesh exposure rates. METHODS: This a retrospective cohort study at a tertiary care referral center from 2011 to 2018. Subjects were identified using Current Procedural Terminology codes. Demographics, operative characteristics, and perioperative complications were abstracted from medical records. RESULTS: Four hundred three women met the inclusion criteria: 91 SLH+SCP and 312 TLH+SCP. Median follow-up was 52 weeks with an overall mesh exposure rate of 1.5%. Follow-up was available for 90% of patients at 4 months and 51% at 1 year. Half of patients had lightweight mesh (n = 203), and half had ultralightweight mesh (n = 200). Vaginal mesh fixation was performed with permanent suture in 86% (n = 344) and delayed absorbable suture in 14% (n = 56) of patients. At 4 months, vaginal mesh exposure rates did not differ between groups (0% SLH vs 1% TLH, p = 1.00). All mesh exposures in the study period occurred with lightweight mesh in the TLH arm. No differences were noted in 1-year mesh exposure rates, 30-day perioperative complications (p = 0.57), or midurethral mesh exposure rates at 4 months (p = 0.35) and 1 year (p = 1.00) between groups. CONCLUSIONS: Short-term mesh exposure following SCP with ultralightweight and lightweight polypropylene mesh is rare regardless of type of hysterectomy and much lower than reported in earlier studies with heavier weight mesh. These data suggest TLH at the time of SCP is a safe option in appropriately counseled patients.

The Leadership Landscape: The Role of Gender in Current Leadership Positions in Obstetrics and Gynecology Departments.

STUDY OBJECTIVE: To describe the proportion of female faculty in departmental administrative and educational leadership roles in Obstetrics and Gynecology departments. DESIGN: Cross-sectional observational study (II-3). SETTING: Accredited Obstetrics and Gynecology residency programs. PARTICIPANTS: A total of 288 accredited residency programs were identified from 2019 to 2020 with 1237 individuals in leadership positions. INTERVENTIONS: Similar to a 2012 to 2013 survey by Hofler et al, residency program websites and corresponding fellowships (Maternal Fetal Medicine, Female Pelvic Medicine and Reconstructive Surgery, Reproductive Endocrinology and Infertility, and Gynecologic Oncology), departmental websites, and divisional websites were queried for those in administrative and educational leadership positions. Information regarding gender (as determined by the surrogates of name and photographic gender expression), medical and academic degrees, academic rank, and subspecialty certification was abstracted. MEASUREMENTS AND MAIN RESULTS: Within administrative leadership roles, women comprised 29% of chairs, 46% of vice chairs, and 47% of division directors, all significantly lower than men in administrative leadership (p <.001). In educational leadership, women made up 71% of medical school clerkship directors, 58% of residency directors, and 50% fellowship directors. Women were more likely to hold educational leadership positions (56% vs 40%; p <.001), although men were more likely to hold administrative leadership positions (68% vs 52%; p <.001). Among subspecialties, there was greatest gender equity within Female Pelvic Medicine and Reconstructive Surgery. Female leaders were more likely to have received additional academic degrees (e.g. MBA, MPH) than their male counterparts (19% vs 13%; p = .002). CONCLUSION: Women continue to be underrepresented in administrative leadership positions. Compared with 2012 to 2013, there is only a 9% increase in proportion of women chairing and 10% vice chairing Obstetrics and Gynecology departments; however, the increase is more substantial in other positions, such as division directors (17%). Our findings demonstrate ongoing gender disparity in the highest levels of departmental leadership and the need to further improve on diversity and gender equity within leadership roles.

Safety of Abdominoplasty with Concomitant Abdominal or Minimally Invasive Hysterectomy: An ACS NSQIP Study.

BACKGROUND: To compare 30-day postoperative complications following abdominoplasty with and without concomitant hysterectomy. Our secondary objective was to compare outcomes following abdominoplasty by route of hysterectomy. METHODS: This was a retrospective cohort study using American College of Surgeons National Surgical Quality Improvement Program (NSQIP) Database from 2014 to 2018. We included women who underwent abdominoplasty alone (ABP) and abdominoplasty with concomitant hysterectomy (ABP+Hyst). The ABP+Hyst group included both abdominal hysterectomy (ABP+AH) and minimally invasive hysterectomy (ABP+MIH). RESULTS: Analysis included 9064 women of whom 2.4% had ABP+Hyst (216 ABP+AH and 53 ABP+MIH). Both ABP and ABP+Hyst had similar 30-day postoperative complication rates (11.5% vs. 14.1%, p=.22). Patients with ABP+Hyst had a longer length of hospital stay when compared to ABP alone [2 days (IQR 1-2) vs. 1 day (IQR 0-2), p<.001). Operating time was longer in ABP+Hyst by 76 minutes (p<.001). In a multivariable logistic regression model controlling for age, race, BMI, ASA class, smoking status, hysterectomy, operative time, and major medical comorbidity, concomitant hysterectomy was not associated with increased odds of 30-day postoperative complications. Both ABP+AH and ABP+MIH had low 30-day complication rates (15.3% vs. 9.4%, p=.273). However, ABP+MIH had a 38 minute longer median operating time (p=.008) but with a shorter length of stay by 1 day (p<.001). CONCLUSION: Concomitant hysterectomy at the time of abdominoplasty was not associated with an increase in complications during the first 30-days after surgery regardless of route of hysterectomy. These data suggest that selected patients can safely be offered combined surgery. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Trends and Risk Factors for Vaginal Cuff Dehiscence after Laparoscopic Hysterectomy.

STUDY OBJECTIVE: The primary objective was to assess the effect of the route of closure of the vaginal cuff on the incidence of vaginal cuff dehiscence (VCD) in laparoscopic hysterectomy (LH). The secondary objective was to assess patient- and surgical-risk factors associated with VCD, rate of perioperative complications by route of closure, and impact of surgeon volume on complications. DESIGN: Retrospective chart review with case-control component. SETTING: Tertiary care center (main hospital and regional hospitals). PATIENTS: A total of 1278 women underwent LH or robot-assisted hysterectomy in 2016, and met the inclusion criteria. Independently, 26 cases of VCD were identified from 2009 through 2016. INTERVENTIONS: A retrospective comparison of patients with vaginal cuff closure and laparoscopic cuff closure (LCC) undergoing LH or robot-assisted hysterectomy in 2016. Patients with VCD from 2009 through 2016 (n = 26) were matched by route of cuff closure to the next 7 patients who underwent hysterectomies (n = 182), who became controls. MEASUREMENTS AND MAIN RESULTS: In 2016, there were 9 cases of VCD (0.70%). There was no significant difference in VCD between LCC (8/989; 0.81%) and vaginal cuff closure (1/289; 0.35%; p = .41). Seven VCD cases were performed by high-volume surgeons (>30 hysterectomies per year) who were more likely to perform LCC and use barbed suture. There were no significant differences in the rates of perioperative complications or surgeon volume between routes of cuff closure. The case-control patients differed in smoking status (p = .010) and history of prior laparotomy (p = .017). Logistic regression showed that increasing age (odds ratio 0.95; 95% confidence interval, 0.91-0.99) and increasing body mass index (odds ratio 0.98; 95% confidence interval, 0.83-0.97) were protective for VCD. CONCLUSION: VCD is a rare but serious complication of LH. Despite previous studies, we did not find a significant difference in VCD or intra- and perioperative complications by route of cuff closure or surgeon volume. Given the lack of evidence favoring one route of cuff closure, we recommend that, to optimize patient outcomes, surgeons employ the closure technique that they are best accustomed to.

Evaluation of Positioning Devices for Optimization of Outcomes in Laparoscopic and Robotic-Assisted Gynecologic Surgery.

In this review, we evaluate techniques, devices, and equipment for patient positioning and their effect on patient outcomes, such as cephalad slide and neuropathy, in laparoscopic and robotic-assisted gynecologic surgery. We conducted a systematic review by searching MEDLINE, Embase, and Cochrane Library for relevant articles published over a 15-year period. Study selection, data extraction, and quality assessment were performed by 2 reviewers independently. Seven articles, including 3 randomized controlled trials and 4 case series, were included in our analysis. Four studies evaluated cephalad patient slide. In 2 randomized controlled trials (n = 103), the mean slide with various devices (i.e., memory foam, bean bag with shoulder braces, egg crate, and gel pad) ranged from 1.07 ± 1.93 cm to 4.5 ± 4.0 cm. The use of a bean bag with shoulder supports/braces was associated with minimal slide, with a median slide of 0 cm (range, 0-2 cm) in a retrospective series and with mean slide of 1.07 ± 1.93 cm in a randomized controlled trial (vs memory foam). No conclusive effect of body mass index on slide could be identified. Five studies evaluating the incidence of neuropathy found an overall incidence of 0.16% and no differences among slide-preventing devices. The minimal slide described across studies supports the conclusion that any of the currently used devices and techniques for safe patient positioning are within reason. The low overall incidence of neuropathy is also reassuring. Best evidence recommendations cannot be made for a specific device or technique; our findings suggest the importance of strict adherence to the basic tenets of safe patient positioning to minimize slide and prevent nerve injury.

The impact of surgeon volume on perioperative adverse events in women undergoing minimally invasive hysterectomy for the large uterus.

BACKGROUND: There are currently sparse data on the relationship between surgeon- and patient-related factors and perioperative morbidity in the setting of elective hysterectomy for the larger uterus. OBJECTIVE: We sought to evaluate the impact of surgeon case volume on perioperative adverse events in women undergoing minimally invasive hysterectomy for uteri >250 g. STUDY DESIGN: This is a retrospective cohort study of all women who underwent total vaginal, total laparoscopic, laparoscopic-assisted vaginal, or robotic-assisted total laparoscopic hysterectomy from January 2014 through July 2016. Hysterectomy was performed for: fibroids, pelvic pain, abnormal uterine bleeding, or prolapse. Patients were identified by Current Procedural Terminology codes and the systemwide electronic medical record was queried for demographic and perioperative data. Perioperative adverse events were defined a priori and classified using the Clavien-Dindo scale. Surgeon case volume was defined as the mean number of minimally invasive hysterectomy cases performed per month by each surgeon during the study period. RESULTS: In all, 763 patients met inclusion criteria: 416 (54.5%) total laparoscopic hysterectomy, 196 (25.7%) robotic-assisted total laparoscopic hysterectomy, 90 (11.8%) total vaginal hysterectomy, and 61 (8%) laparoscopic-assisted vaginal hysterectomy. Mean (±SD) age was 47.3 ± 6.1 years, and body mass index was 31.1 ± 7.4 kg/m2. In all, 66 surgeons performed minimally invasive hysterectomy for uteri >250 g during the study period, and the median rate of minimally invasive hysterectomy cases for large uteri per month was 3.4 (0.4-3.7) cases/month. The median (IQR) uterine weight was 409 (308-606.5) g. The rate of postoperative adverse events Dindo grade >2 was 17.8% (95% confidence interval, 15.2-20.7). The overall rate of intraoperative adverse events was 4.2% (95% confidence interval, 2.9-5.9). The rate of conversion to laparotomy was 5.5% (95% confidence interval, 4.0-7.4). There was no significant difference in adverse event rates between the routes of minimally invasive hysterectomy cases (25.6% vs 17.5% vs 18.0% vs 14.8% for total laparoscopic hysterectomy, robotic-assisted laparoscopic hysterectomy, total vaginal hysterectomy, and laparoscopic-assisted vaginal hysterectomy, respectively, P = .2). In a logistic regression model controlling for age, body mass index, uterine weight, operating time, and history of laparotomy, higher monthly minimally invasive hysterectomy volume was significantly associated with the likelihood that a patient would experience a postoperative adverse event (adjusted odds ratio, 1.1 for each additional minimally invasive hysterectomy case for large uteri per month; 95% confidence interval, 1.0-1.3). When controlling for the same variables, a higher incidence of intraoperative complications was significantly associated with monthly minimally invasive hysterectomy case volume (adjusted odds ratio, 1.5 for each additional minimally invasive hysterectomy case for large uteri per month; 95% confidence interval, 1.20-2.08). Increasing age was associated with a lower incidence of complications (adjusted odds ratio, 0.9 for each additional year; 95% confidence interval, 0.8-0.9). Higher monthly minimally invasive hysterectomy volume was associated with a lower rate of conversion from a minimally invasive approach to laparotomy (adjusted odds ratio, 0.4 for each additional minimally invasive hysterectomy case for large uteri per month; 95% confidence interval, 0.2-0.5). CONCLUSION: The overall rate of serious adverse events associated with minimally invasive hysterectomy for uteri >250 g was low. Higher monthly minimally invasive hysterectomy case volume was associated with a higher rate of intraoperative and postoperative adverse events but was associated with a lower rate of conversion to laparotomy.

B-1b Cells Secrete Atheroprotective IgM and Attenuate Atherosclerosis.

RATIONALE: B cells contribute to atherosclerosis through subset-specific mechanisms. Whereas some controversy exists about the role of B-2 cells, B-1a cells are atheroprotective because of secretion of atheroprotective IgM antibodies independent of antigen. B-1b cells, a unique subset of B-1 cells that respond specifically to T-cell-independent antigens, have not been studied within the context of atherosclerosis. OBJECTIVE: To determine whether B-1b cells produce atheroprotective IgM antibodies and function to protect against diet-induced atherosclerosis. METHODS AND RESULTS: We demonstrate that B-1b cells are sufficient to produce IgM antibodies against oxidation-specific epitopes on low-density lipoprotein both in vitro and in vivo. In addition, we demonstrate that B-1b cells provide atheroprotection after adoptive transfer into B- and T-cell deficient (Rag1(-/-)Apoe(-/-)) hosts. We implicate inhibitor of differentiation 3 (Id3) in the regulation of B-1b cells as B-cell-specific Id3 knockout mice (Id3(BKO)Apoe(-/-)) have increased numbers of B-1b cells systemically, increased titers of oxidation-specific epitope-reactive IgM antibodies, and significantly reduced diet-induced atherosclerosis when compared with Id3(WT)Apoe(-/-) controls. Finally, we report that the presence of a homozygous single nucleotide polymorphism in ID3 in humans that attenuates Id3 function is associated with an increased percentage of circulating B-1 cells and anti-malondialdehyde-low-density lipoprotein IgM suggesting clinical relevance. CONCLUSIONS: These results provide novel evidence that B-1b cells produce atheroprotective oxidation-specific epitope-reactive IgM antibodies and protect against atherosclerosis in mice and suggest that similar mechanisms may occur in humans.

Obesity and Reconstructive Pelvic Surgery: An ACS NSQIP Study.

IMPORTANCE: Obesity is steadily increasing in the United States and is a risk factor for many medical and surgical complications. Literature is limited regarding obesity as an independent risk factor for perioperative complications after reconstructive pelvic surgery (RPS). OBJECTIVE: This study aimed to analyze the association of obesity on 30-day perioperative complications after RPS. STUDY DESIGN: This was a database study comparing perioperative complications after RPS of obese versus nonobese patients using the American College of Surgeons National Surgical Quality Improvement Program. Patients who underwent surgery for uterovaginal or vaginal vault prolapse were selected, and perioperative outcomes were compared between obese and nonobese patients. Obesity was defined as a body mass index ≥30 (calculated as weight in kilograms divided by height in meters squared). RESULTS: A total of 13,302 patients met the inclusion criteria and were included in this study; 4,815 patients were obese, whereas 8,487 were nonobese. The overall rate of any 30-day postoperative complication was 6.8%, and the rate of complications did not differ between groups. Superficial and organ space surgical site infections were significantly higher in the obese cohort, whereas nonobese patients were more likely to receive a blood transfusion. A multivariable logistic regression model was performed with variables that were statistically significant on bivariate analysis and deemed clinically significant. Variables included obesity, age, American Society of Anesthesiologists class, current smoker, diabetes, hypertension, operative time, colpopexy, and obliterative procedure. After controlling for potential confounding factors, obesity was not associated with any 30-day postoperative complications after pelvic organ prolapse surgery. CONCLUSION: Obesity was not associated with 30-day postoperative complications after RPS after controlling for possible confounding variables.

Suture-Needle Management Device and Novel Port Configuration for Robotic Sacrocolpopexy.

IMPORTANCE: Robot-assisted sacrocolpopexy (SCP) is a commonly performed procedure for the repair of apical pelvic organ prolapse; therefore, novel devices and techniques to improve safety and efficacy of this procedure should be explored. OBJECTIVE: The objective of this study was to assess safety and efficacy of 8-mm trocar site for use of a disposable suture/needle management device (StitchKit; Origami Surgical, Madison, NJ) for robot-assisted SCP with a 4-arm configuration and no assistant port. STUDY DESIGN: This is a retrospective case series of patients undergoing robot-assisted SCP at a tertiary center from 2018 to 2021. All surgical procedures were performed using four 8-mm robotic trocars and StitchKit device. Our objective was to review all cases in which this technique was used to determine whether the approach resulted in a safely completed procedure and any complications or adverse events. Secondary objectives were to describe patient and operative characteristics. RESULTS: In total, 422 patients underwent robot-assisted SCP for pelvic organ prolapse. The mean age was 60 ± 10 years, and mean body mass index was 27 ± 6 (calculated as weight in kilograms divided by height in meters squared). Most patients had stage 3 prolapse (73%) and underwent concomitant hysterectomy (70%). Ninety-nine percent (n = 416) of cases were completed robotically. StitchKit was successfully inserted and removed in all robotic cases with correct needle counts. All patients had postoperative visits, and 80% followed up at 3 months. No umbilical/port site hernias, operative site infections, or adverse events were reported. CONCLUSIONS: Robot-assisted SCP can be performed safely using a 4-arm robotic configuration and suture kit device. This setup eliminates incisions greater than 8 mm and an assistant port, allowing for surgical efficiency without compromising patient outcomes.

Patient Satisfaction With Telehealth Visits for New Patient Appointments for Pelvic Floor Disorders: A Randomized Trial of Telehealth Versus Standard In-Person Office Visits.

IMPORTANCE: The acceptability and safety of telehealth have been reported in urogynecology for preoperative and postoperative care but not new patient consultation. OBJECTIVES: This study aimed to determine if new patient telehealth encounters are noninferior to in-person encounters for women presenting to a urogynecology clinic using a satisfaction questionnaire. Secondary objectives were to describe patient experiences and follow-up. STUDY DESIGN: A randomized controlled trial of telehealth versus in-person consults for new patients with any urogynecologic condition was conducted. Patients completed the validated Patient Satisfaction Questionnaire 18 (PSQ-18) after the visit. The primary outcome was composite PSQ-18 score. Using a noninferiority margin of 5 points on the PSQ-18, 25 patients per arm were required with a power of 80% and an α of 0.05. RESULTS: From March to September 2021, 133 patients were screened, 71 were randomized, and 58 were included in the final analysis (30 telehealth and 28 in-person). Demographic characteristics were similar between groups. Patient Satisfaction Questionnaire 18 composite scores were high for both groups but higher for in-person versus telehealth visits (75.68 ± 8.55 vs 66.60 ± 11.80; P = 0.001; difference, 9.08); results were inconclusive with respect to noninferiority. Women in the telehealth group expressed uncertainty regarding the telehealth format. There were no differences in short-term follow-up, communication with the office, or treatment chosen between groups. CONCLUSIONS: Women seen by urogynecologic providers for a new consult both via in-person or telehealth visits demonstrated high satisfaction with their first visit. We were unable to determine if telehealth is noninferior to in-person visits. Our study adds to the literature that telehealth is safe, effective, and acceptable to patients.

Headache in children with Tourette syndrome.

OBJECTIVE: The authors analyzed the frequency of occurrence of headaches in children and adolescents with Tourette syndrome (TS) to address their possible inclusion as a comorbidity. STUDY DESIGN: Using a prospective questionnaire, administered directly, we interviewed a total sample size of 109 patients with TS ≤ 21 years of age. The questionnaires were then analyzed according to the International Headache Society's diagnostic criteria. RESULTS: We found headaches to be present in 55% of the patients, with the 2 most common headache types being migraine headaches and tension-type headaches. The rate of migraine headache within the TS group was found to be 4 times greater than that of the general pediatric population, as reported in the literature. In addition, the rate of tension-type headache was found to be more than 5 times greater than that of the general pediatric population. CONCLUSIONS: Overall, the high rates of migraine and tension-type headache within this population support the proposition that headaches are a comorbidity of TS.

Patient-Centered Outcomes After Modified Vestibulectomy.

OBJECTIVE: To describe patient outcomes after modified vestibulectomy for vulvodynia. METHODS: This is a mixed-methods study of patients who had undergone modified vestibulectomy for vulvodynia at a tertiary care hospital from 2009 through 2016. Demographics, preoperative and postoperative examinations, symptoms, and treatments were obtained through retrospective review. Prospective semistructured interviews were conducted from 2018 through 2019 to address patient-reported changes in pain and sexual function. Qualitative analysis was performed using a grounded theory approach. RESULTS: Twenty-two patients underwent modified vestibulectomy from 2009 through 2016. Age ranged from 22 to 65 years and mean body mass index was 24.3±5.4. The majority of patients were premenopausal (57%), sexually active (68%), and partnered (76%). Postoperatively, data on pain improvement were retrieved on 18 patients, of which 17 (94%) reported improvement. Patients used pelvic floor physical therapy, medications, and lubricants both preoperatively and postoperatively. For the qualitative analysis, thematic saturation was achieved with 14 interviews. Of 14 participants interviewed, 13 (93%) reported improvement with pain after surgery, 11 (79%) reported satisfaction with surgery, 8 (57%) reported satisfaction with sexual function, and 11 (79%) reported recommending the surgery to others. The following lead themes were identified: vulvodynia symptoms significantly affect quality of life; there is difficulty and delay in diagnosis owing to lack of information and awareness among patients and health care providers; and surgical success and satisfaction are influenced by patient perceptions with sexual dysfunction often persisting despite vulvar pain improvement. CONCLUSION: Vulvodynia patients report improvement in pain and high overall satisfaction after modified vestibulectomy, but more variable long-term effects on sexual function.

Efficacy of Radiofrequency Ablation versus Transarterial Chemoembolization for Patients with Solitary Hepatocellular Carcinoma ≤3 cm.

Optimal treatment for small hepatocellular carcinoma (HCC) ≤ 3 cm remains controversial. Ablation and chemoembolization are considered for nonoperative candidates. This study compares survival among patients with solitary HCC ≤ 3 cm treated with radiofrequency ablation (RFA) and transarterial chemoembolization (TACE). Patients diagnosed with HCC ≤ 3 cm between 2005 and 2014 were included. Kaplan-Meier survival functions with log-rank tests were used to estimate recurrence-free survival and overall survival (OS) survival. Among 161 patients with solitary HCC ≤ 3 cm, 145 patients with mean age of 65.2 years (±9.2) and 95 per cent prevalence of cirrhosis had operative treatment or TACE, and/or RFA. From this cohort, 27 (19%) patients had TACE, 27 (19%) patients had RFA, and 15 (10%) patients had TACE/RFA. The patients treated with definitive TACE, RFA, or TACE/RFA had a similar 1-year recurrence-free survival (23% vs 27% vs 36%, respectively, P = 0.445) and similar 5-year OS (21% vs 24% vs 33%, respectively, P = 0.287). Thirty-five (24%) patients were bridged to transplantation with TACE and/or RFA. The 5-year OS was significantly improved in patients bridged to transplantation (P < 0.001). Survival does not differ between patients with solitary HCC ≤ 3 cm treated with TACE or RFA. Patients who were bridged to transplantation had significantly greater OS compared with patients who were not transplanted.

Morbidity and Mortality After Gastrectomy: Identification of Modifiable Risk Factors.

BACKGROUND: Morbidity after gastrectomy remains high. The potentially modifiable risk factors have not been well described. This study considers a series of potentially modifiable patient-specific and perioperative characteristics that could be considered to reduce morbidity and mortality after gastrectomy. METHODS: This retrospective cohort study includes adults in the ACS NSQIP PUF dataset who underwent gastrectomy between 2011 and 2013. Sequential multivariable models were used to estimate effects of clinical covariates on study outcomes including morbidity, mortality, readmission, and reoperation. RESULTS: Three thousand six hundred and seventy-eight patients underwent gastrectomy. A majority of patients had distal gastrectomy (N = 2,799, 76.1 %) and had resection for malignancy (N = 2,316, 63.0 %). Seven hundred and ninety-eight patients (21.7 %) experienced a major complication. Reoperation was required in 290 patients (7.9 %). Thirty-day mortality was 5.2 %. Age (OR = 1.01, 95 % CI = 1.01-1.02, p = 0.001), preoperative malnutrition (OR = 1.65, 95 % CI = 1.35-2.02, p < 0.001), total gastrectomy (OR = 1.63, 95 % CI = 1.31-2.03, p < 0.001), benign indication for resection (OR = 1.60, 95 % CI = 1.29-1.97, p < 0.001), blood transfusion (OR = 2.57, 95 % CI = 2.10-3.13, p < 0.001), and intraoperative placement of a feeding tubes (OR = 1.28, 95 % CI = 1.00-1.62, p = 0.047) were independently associated with increased risk of morbidity. Association between tobacco use and morbidity was statistically marginal (OR = 1.23, 95 % CI = 0.99-1.53, p = 0.064). All-cause postoperative morbidity had significant associations with reoperation, readmission, and mortality (all p < 0.001). CONCLUSIONS: Mitigation of perioperative risk factors including smoking and malnutrition as well as identified operative considerations may improve outcomes after gastrectomy. Postoperative morbidity has the strongest association with other measures of poor outcome: reoperation, readmission, and mortality.

Sleep disorders in children with Tourette syndrome.

BACKGROUND: The objective of this study was to determine the frequency, nature, and impact of sleep disorders in children and adolescents with Tourette syndrome and to raise awareness about their possible inclusion as a Tourette syndrome comorbidity. METHODS: Using a prospective questionnaire, we interviewed 123 patients of age ≤21 years with a confirmed diagnosis of Tourette syndrome. Each completed questionnaire was then reviewed in accordance with Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria for categorization to a form of sleep disorder. RESULTS: Of the 123 patients with Tourette syndrome, 75 (61%) had comorbid attention deficit hyperactivity disorder and 48 (39%) had Tourette without attention deficit hyperactivity disorder. The sleep problems observed included problems in the nature of sleep, abnormal behaviors during sleep, and impact of sleep disturbances on quality of life. Within these cohorts, 31 (65%) of the 48 Tourette-only patients and 48 (64%) of the 75 Tourette + attention deficit hyperactivity disorder patients could fit into some form of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, coded sleep disorders. Of the 48 Tourette + attention deficit hyperactivity disorder patients with sleep disorders, 36 (75%) had insomnia signs, which could be explained by the co-occurrence of attention deficit hyperactivity disorder and high stimulant use. However, 10 (32%) of the 31 Tourette-only patients with sleep disorders had insomnia irrespective of attention deficit hyperactivity disorder or medication use. CONCLUSIONS: Sleep problems are common in children with Tourette syndrome irrespective of comorbid attention deficit hyperactivity disorder, justifying their inclusion as a comorbidity of Tourette syndrome.

S100A12 expression in thoracic aortic aneurysm is associated with increased risk of dissection and perioperative complications.

OBJECTIVES: The purpose of this study was to determine the relevance of S100A12 expression to human thoracic aortic aneurysms and type A thoracic aortic aneurysm dissection and to study mechanisms of S100A12-mediated dysfunction of aortic smooth muscle cells. BACKGROUND: Transgenic expression of proinflammatory S100A12 protein in murine aortic smooth muscle causes thoracic aneurysm in genetically modified mice. METHODS: Immunohistochemistry of aortic tissue (n = 50) for S100A12, myeloperoxidase, and caspase 3 was examined and S100A12-mediated pathways were studied in cultured primary aortic smooth muscle cells. RESULTS: We found S100A12 protein expressed in all cases of acute thoracic aortic aneurysm dissection and in approximately 25% of clinically stable thoracic aortic aneurysm cases. S100A12 tissue expression was associated with increased length of stay in patients undergoing elective surgical repair for thoracic aortic aneurysm, despite similar preoperative risk as determined by European System for Cardiac Operative Risk Evaluation. Reduction of S100A12 expression in human aortic smooth muscle cells using small hairpin RNA attenuates gene and protein expression of many inflammatory- and apoptosis-regulating factors. Moreover, genetic ablation of the receptor for S100A12, receptor for advanced glycation end products (RAGE), in murine aortic smooth muscle cells abolished cytokine-augmented activation of caspase 3 and smooth muscle cell apoptosis in S100A12-expressing cells. CONCLUSIONS: S100A12 is enriched in human thoracic aortic aneurysms and dissections. Reduction of S100A12 or genetic ablation of its cell surface receptor, the receptor for advanced glycation end products (RAGE), in aortic smooth muscle resulted in decreased activation of caspase 3 and in reduced apoptosis. By establishing a link between S100A12 expression and apoptosis of aortic smooth muscle cells, this study identifies novel S100A12 signaling pathways and indicates that S100A12 may be a useful molecular marker and possible target for treatment for human aortic diseases.
