Association of Socioeconomic Status with Empowerment,Depression, and Anxiety in Pregnancies Complicated by Fetal Surgical Anomalies

BackgroundWomen with pregnancies complicated by fetal surgical anomalies experience significant psychosocial burden. There remains a need to determine the impact that socioeconomic status has on maternal empowerment, anxiety, and depression.MethodsA survey study was conducted from 5/2021–5/2022 to quantify empowerment, anxiety, and depression in women with fetal surgical anomalies. Surveys administered included Pregnancy Related Empowerment Scale (PRES), Patient Empowerment Scale (PES), State Trait Anxiety Inventory (STAI), and Depression Anxiety and Stress Scale (DASS). Two-sample t-test was used to compare survey scores across socioeconomic groups.ResultsSeventy-four patients were recruited. Mothers more commonly preferred English as primary language (n = 61, 82%) and were non-Hispanic (n = 43, 58%). Lower empowerment scores were observed in Hispanic mothers (PRES, p = 0.03; PES, p = 0.04) and mothers who preferred Spanish (PRES, p = 0.04; PES, p = 0.06) as primary language. Both non-Hispanic (p = 0.88) and English speaking (p = 0.75) women had higher STAI scores, but neither was significantly different. DASS was not significantly higher for Hispanic (p = 0.79) or Spanish speaking mothers (p = 0.47).ConclusionHispanic and Spanish speaking women with pregnancies complicated by fetal surgical anomalies have significantly decreased empowerment scores. These findings suggest a need for development of culturally competent, targeted interventions to improve maternal empowerment in this high-risk population.Level of EvidenceLevel II.Type of StudyCross-Sectional Survey Study.     

Distribution and Surgical Management of Visceral Ewing Sarcoma Among Children and Adolescents

IntroductionEwing sarcoma (EWS) is a highly malignant tumor of bone and soft tissue that occasionally arises from viscera. Visceral EWS (V-EWS) is challenging to manage given its varied organ distribution and often late-stage presentation. We aimed to characterize our institutional experience with V-EWS, focusing on its surgical management, and to compare V-EWS outcomes against those with osseous (O-EWS) and soft tissue EWS (ST-EWS).MethodsRetrospective review of all EWS patients ≤21 years presenting to a single institution between 2000 and 2022. Patient- and disease-specific characteristics were compared. Overall and relapse-free survival were estimated using Kaplan Meier methods and log-rank test.Results156 EWS patients were identified: 117 O-EWS, 20 ST-EWS, and 19 V-EWS. V-EWS arose in the kidney (n = 5), lung (n = 5), intestine (n = 2), esophagus (n = 1), liver (n = 1), pancreas (n = 1), adrenal gland (n = 1), vagina (n = 1), brain (n = 1), and spinal cord (n = 1). No significant demographic differences were detected between EWS groups. V-EWS was more frequently metastatic at presentation (63.2%; p = 0.005), yet no significant overall or relapse-free survival differences emerged between EWS groups, with similar follow-up intervals. While V-EWS required multiple unique operative strategies to gain primary control, no significant difference in treatment strategies appeared between groups. Surgery-only primary control was associated with improved overall and relapse-free survival in all groups.ConclusionsV-EWS presents unique management challenges in children and adolescents given its variable sites of origin. This large cohort is the first to describe the surgical management and outcomes of V-EWS, demonstrating more frequent metastatic presentation, while achieving similar survival across groups.Level of evidenceLevel 2 – Cohort Study.     

Chest Wall Reconstruction in Pediatric Patients with Chest Wall Tumors: A Systematic Review

BackgroundResection of pediatric chest wall tumors can result in large defects requiring reconstruction for function and cosmesis. Multiple reconstructive methods have been described. We performed a systematic review of the literature to describe commonly used approaches and outcomes.MethodsA systematic literature search was performed for English-language publications describing chest wall tumor resection and reconstruction using implantable materials in patients ≤21 years, excluding soft tissue resection only, sternal resection, and reconstruction by primary repair or muscle flaps alone. Data were collected on diagnoses, reconstructive method, and outcomes. Rigid chest wall reconstruction was compared to mesh reconstruction.ResultsThere were 55 articles with 188 patients included. The median age was 12 years. Most tumors were malignant (n = 172, 91.5%), most commonly Ewing's sarcoma (n = 65, 34.6%), followed by unspecified sarcomas (n = 34, 18.1%), Askin's tumor (n = 16, 8.5%; a subset of Ewing's sarcoma) and osteosarcoma (n = 16, 8.5%). A median of 3 ribs were resected (range 1–12). Non-rigid meshes were most common (n = 138, 73.4%), followed by rigid prostheses (n = 50, 26.6%). There were 19 post-operative complications (16.8%) and 22.2% of patients developed scoliosis. There were no significant differences in complications (20.5% rigid vs. 10.6% non-rigid, p = 0.18) or scoliosis (22.7% vs. 14.0%, p = 0.23) by reconstruction method, but complications after rigid reconstruction were more likely to require surgery (90.0% vs. 53.9%, p = 0.09). The median follow-up duration was 24 months.ConclusionsIn this review of the literature, there were no significant differences in overall post-operative complications or scoliosis development by reconstruction method, yet complications after rigid reconstruction were more likely to require surgical intervention.Level of evidenceLevel IV.     

Management of Primary Spontaneous Pneumothorax in Children: A Single Institution Protocol Analysis

BackgroundThe Midwest Pediatric Surgery Consortium (MWPSC) suggested a simple aspiration of primary spontaneous pneumothorax (PSP) protocol, failing which, Video-Assisted Thoracoscopic Surgery (VATS) should be considered. We describe our outcomes using this suggested protocol.MethodsA single institution retrospective analysis was conducted on patients between 12 and 18 years who were diagnosed with PSP from 2016 to 2021. Initial management involved aspiration alone with a ≤12 F percutaneous thoracostomy tube followed by clamping of the tube and chest radiograph at 6 h. Success was defined as ≤2 cm distance between chest wall and lung at the apex and no air leak when the clamp was released. VATS followed if aspiration failed.ResultsFifty-nine patients were included. Median age was 16.8 years (IQR 15.9, 17.3). Aspiration was successful in 33% (20), while 66% (39) required VATS. The median LOS with successful aspiration was 20.4 h (IQR 16.8, 34.8), while median LOS after VATS was 3.1 days (IQR 2.6, 4). In comparison, in the MWPSC study, the mean LOS for those managed with a chest tube after failed aspiration was 6.0 days (±5.5). Recurrence after successful aspiration was 45% (n = 9), while recurrence after VATS was 25% (n = 10). Median time to recurrence after successful aspiration was sooner than that of the VATS group [16.6 days (IQR 5.4, 19.2) vs. 389.5 days (IQR 94.1, 907.0) p = 0.01].ConclusionSimple aspiration is safe and effective initial management for children with PSP, although most will require VATS. However, early VATS reduces length of stay and morbidity.Level of evidenceIV. Retrospective study.     

Canadian Pediatric Surgeon Workforce: Characterization of Training,Trends Over Time,and 10-year Model for Pediatric Surgery Need

BackgroundGraduate and fellowship training trends for Canadian pediatric surgeons remain uncharacterized. Similarly, updated workforce planning for pediatric surgeons is required. We aimed to characterize graduate degree and fellowship trends for Canadian pediatric surgeons, with modelling to inform workforce planning.MethodsWe performed a cross sectional observational study evaluating Canadian pediatric surgeons in January 2022. Surgeon demographics collected included year of medical degree (MD) conferment, MD location, fellowship location, and graduate degree achievement. Our primary outcome was to evaluate training characteristics over time. Secondary outcomes evaluated surgeon supply and demand from 2021 to 2031. Supply was extrapolated from current Canadian pediatric surgery fellows assuming static fellowship matriculation, while retirement was estimated using a 31-, 36-, or 41-year career following MD conferral.ResultsOf included surgeons (n = 77), 64 (83%) completed fellowship training in Canada and 46 (60%) have graduate degrees. No surgeons graduating ≤1980 hold graduate degrees, compared to 8 (100%) surgeons with MD ≥ 2011 (p < 0.001). Similarly, more surgeons with MD ≥ 2011 appear to have a Canadian MD (n = 7, 87.5%) and Canadian fellowship (n = 8, 100%). Modelling predicts that 19–49 (25%–64%) surgeons will retire between 2021 and 2031, while 37 fellows will graduate with intention to work in Canada, creating between a 12 surgeon deficit up to an 18 surgeon surplus depending on career length.ConclusionsTrends in graduate degree achievement and fellowship location suggest increasing competition for Canadian pediatric surgery positions. Additionally, a substantial number of Canadian-trained fellows will need positions outside of Canada in the next decade. Overall, results support previous work demonstrating saturation of the Canadian pediatric workforce.Level of EvidenceLevel IV.ACGME Competency AddressedMedical Knowledge.     

Retroperitoneoscopic Pyeloplasty for Ureteropelvic Junction Obstruction in Children: Value of Robotic Assistance

AimRetroperitoneal pyeloplasty (RP) for pediatric ureteropelvic junction obstruction (UPJO) performed using retroperitoneoscopy (retro-RP) or robotic assistance (robo-RP) were compared.MethodsAll subjects were Japanese, matched for age, weight, and RP diameters. All RP were performed in the lateral decubitus position at a single institute by the same team using identical protocols. Five independent surgeons were asked to score intraoperative video recordings for perceived difficulty of suturing (DOS; 5 = impossible; 4 = difficult; 3 = tedious; 2 = slow; 1 = easy) and rank RP as +1 if robo-RP appeared to be superior, 0 if they appeared to be the same, and −1 if robo-RP appeared to be inferior.ResultsRobo-RP performed 2018-2022 (n = 22) were matched with retro-RP performed 2011-2019 (n = 34). Mean overall operative times were similar (robo-RP: 305.2 ± 57.8 min versus retro-RP: 340.0 ± 117.9 min; p = 0.19), but securing the larger retroperitoneal space required for robo-RP took significantly longer; 50.8 ± 13.9 min versus 24.3 ± 9.6 min; p < 0.0001. Total anastomotic time (TAT) and TAT per suture were both significantly shorter for robo-RP (p < 0.0001). The coefficient of variation for time taken to place one suture was smaller for robo-RP than for retro-RP. DOS was lower for robo-RP with less variance (p < 0.01). Robo-RP had shorter drainage tube insertion, ambulated quicker postoperatively, and shorter hospitalization. Retro-RP had anastomotic complications; leaks (n = 2) and strictures (n = 2, requiring conventional open re-pyeloplasty). Robo-RP had no anastomotic complications and was ranked +1 unanimously.ConclusionsThe RP anastomosis was quicker with less complications and more precise with robotic assistance in matched patients under similar circumstances. Should RP be indicated, robo-RP is recommended.Level of evidenceIII.     

Pediatric Pedestrian Injuries: Striking Too Close to Home

BackgroundPediatric pedestrian injuries (PPI) are a major public health concern. This study utilized geospatial analysis to characterize the risk and injury severity of PPI.MethodsA retrospective chart review of PPI patients (age < 18) from a level 1 trauma center was performed (2013–2020). A geographic information system geocoded injury location to home and other public landmarks. Incidents were aggregated to zip codes and the Local Indicators of Spatial Association statistic tested for spatial clustering of injury rates per 10,000 children. Predictors for increased injury severity were assessed by logistic regression.ResultsPPI encompassed 6% (n = 188) of pediatric traumas. Most patients were black (54%), male (58%), >13 years (56%), and with Medicaid insurance (68%). Nine zip codes comprised a statistically significant cluster of PPI. Nearly half (40%) occurred within a quarter mile of home; 7% occurred at home. Most (65%) PPI occurred within 1 mile of a school, and 45% occurred within a quarter mile of a park. Nearly all (99%) PPI occurred within a quarter mile of a major intersection and/or roadway. Using admission to ICU as a marker for injury severity, farther distance from home (OR 1.060, 95% CI 1.001–1.121, p = 0.045) and age <13 years (3.662, 95% CI 1.854–7.231, p < 0.001) were independent predictors of injury severity.ConclusionsThere are significant sociodemographic disparities in PPI. Most injuries occur near patients’ homes and other public landmarks. Multidisciplinary injury prevention collaboration can help inform policymakers, direct local safety programs, and provide a model for PPI prevention at the national level.Level of EvidenceLevel IV.     

Utilizing a critical airway response team expedites esophageal button battery removal

BackgroundEsophageal button battery ingestion is a significant problem that can lead to significant complications such as tracheoesophageal fistula, esophageal perforation, and aortoesophageal fistula. Due to this, prompt recognition and treatment is integral in the care of these patients.MethodsPatients who presented to a single institution from August 2015 to April 2022 with esophageal button battery ingestion were included in this study. All esophageal button battery ingestion patients were included in a clinical algorithm for Critical Airway Response Team (CART) activation in October 2019. Time from diagnosis to treatment was compared for pre-CART clinical algorithm implementation to post-CART.ResultsData on pre-CART patients (n = 6) and post-CART patients (n = 7) was collected. Including esophageal button battery ingestions to CART activations shortened the time from chest x-ray to button battery removal from 73 ± 32 min to 35 ± 11 min (p < 0.05).ConclusionThese data highlight the importance of implementation of a clinical care algorithm to shorten the time from diagnosis to treatment in patients with esophageal button battery ingestion.Level of evidenceIII.     

Remote Ischaemic Pre-Conditioning Reduces Intestinal Ischaemia Reperfusion Injury in a Newborn Rat

ObjectiveRemote ischaemic conditioning (RIC) has been shown to reduce ischaemia-reperfusion injury(IRI) in multiple organ systems. IRI is seen in multiple bowel pathologies in the newborn, including NEC. We investigated the potential of RIC as a novel therapy for various intestinal pathologies in the newborn.MethodsWe used an established intestinal IRI model in rat pups which results in similar intestinal injury to necrotising enterocolitis (NEC). Animals were randomly allocated to IRI only(n = 14), IRI + RIC(n = 13) or sham laparotomy(n = 10). The macroscopic extent of intestinal injury is reported as a percentage of total small bowel. Injury severity was measured using Chiu-Park scoring. Neutrophil infiltration/activation was assayed by myeloperoxidase activity. Immunohistochemistry was used to assess the expression of hypoxia-inducible factor alpha (HIF-1α). Data are median (interquartile range).ResultsAnimals that underwent RIC showed a decreased extent of macroscopic injury from 100%(85–100%) in the IRI only group to 58%(15–84%, p = 0.003) in the IRI + RIC group. Microscopic injury score was significantly lower in animals that underwent RIC compared to IRI alone (3.5[1.25–5] vs 5.5[4–6], p = 0.014). Intestinal myeloperoxidase activity in animals exposed to IRI was 3.4 mU/mg of tissue (2.5–3.7) and 2.1 mU/mg(1.5–2.8) in the IRI + RIC group(p = 0.047). HIF-1α expression showed a non-significant trend towards reduced expression in the IRI + RIC group.ConclusionsRIC reduces the extent and severity of bowel injury in this animal model, supporting the hypothesis that RIC has therapeutic potential for intestinal diseases in the newborn.     

The Timing of Congenital Diaphragmatic Hernia Repair on Extracorporeal Membrane Oxygenation Impacts Surgical Bleeding Risk

BackgroundThe optimal timing of surgical repair for infants with congenital diaphragmatic hernia (CDH) treated with extracorporeal membrane oxygenation (ECMO) support remains controversial. The risk of surgical bleeding is considered by many centers as a primary factor in determining the preferred timing of CDH repair for infants requiring ECMO support. This study compares surgical bleeding following CDH repair on ECMO in early versus delayed fashion.MethodsA retrospective review of 146 infants who underwent CDH repair while on ECMO support from 1995 to 2021. Early repair occurred during the first 48 h after ECMO cannulation (ER) and delayed repair after 48 h (DR). Surgical bleeding was defined by the requirement of reoperative intervention for hemostasis or decompression.Results102 infants had ER and 44 infants DR. Surgical bleeding was more frequent in the DR group (36% vs 5%, p < 0.001) with an odds ratio of 11.7 (95% CI: 3.48–39.3, p < 0.001). Blood urea nitrogen level on the day of repair was significantly elevated among those who bled (median 63 mg/dL, IQR 20–85) vs. those who did not (median 9 mg/dL, IQR 7–13) (p < 0.0001). Duration of ECMO support was shorter in the ER group (median 13 vs 18 days, p = 0.005). Survival was not statistically different between the two groups (ER 60% vs. DR 57%, p = 0.737).ConclusionWe demonstrate a significantly lower incidence of bleeding and shorter duration of ECMO with early CDH repair. Azotemia was a strong risk factor for surgical bleeding associated with delayed CDH repair on ECMO.Level of evidenceLevel III cohort study.     

Hirschsprung-associated inflammatory bowel disease: A multicenter study from the APSA Hirschsprung disease interest group

Background/PurposeA small number of Hirschsprung disease (HD) patients develop inflammatory bowel disease (IBD)-like symptoms after pullthrough surgery. The etiology and pathophysiology of Hirschsprung-associated IBD (HD-IBD) remains unknown. This study aims to further characterize HD-IBD, to identify potential risk factors and to evaluate response to treatment in a large group of patients.MethodsRetrospective study of patients diagnosed with IBD after pullthrough surgery between 2000 and 2021 at 17 institutions. Data regarding clinical presentation and course of HD and IBD were reviewed. Effectiveness of medical therapy for IBD was recorded using a Likert scale.ResultsThere were 55 patients (78% male). 50% (n = 28) had long segment disease. Hirschsprung-associated enterocolitis (HAEC) was reported in 68% (n = 36). Ten patients (18%) had Trisomy 21. IBD was diagnosed after age 5 in 63% (n = 34). IBD presentation consisted of colonic or small bowel inflammation resembling IBD in 69% (n = 38), unexplained or persistent fistula in 18% (n = 10) and unexplained HAEC >5 years old or unresponsive to standard treatment in 13% (n = 7). Biological agents were the most effective (80%) medications. A third of patients required a surgical procedure for IBD.ConclusionMore than half of the patients were diagnosed with HD-IBD after 5 years old. Long segment disease, HAEC after pull through operation and trisomy 21 may represent risk factors for this condition. Investigation for possible IBD should be considered in children with unexplained fistulae, HAEC beyond the age of 5 or unresponsive to standard therapy, and symptoms suggestive of IBD. Biological agents were the most effective medical treatment.Level of EvidenceLevel 4     

Moment of truth-adding carboplatin to neoadjuvant/adjuvant chemotherapy in triple negative breast cancer improves overall survival: An individual participant data and trial-level Meta-analysis

ImportanceCarboplatin increases the pathological complete remission (pCR) rate in triple negative breast cancer (TNBC) when added to neoadjuvant chemotherapy, however, evidence on its effect on survival outcomes is controversial.MethodsThe study was prospectively registered at PROSPERO (CRD42021228386).We systematically searched PubMed, Embase, Cochrane Central Register of Clinical Trials, and conference proceedings from January 1, 2004 to January 30, 2022 for relevant randomized clinical trials (RCTs) of (neo)adjuvant chemotherapy in TNBC patients, with carboplatin in the intervention arm and standard anthracycline taxane (AT) in the control arm. PRISMA guidelines were used for this review. Data were pooled using fixed and random effects models as appropriate on extracted hazard ratios (HR). Individual patient data (IPD)for disease free survival (DFS) and overall survival (OS) were extracted from published survival curves of included RCTs; DFS and OS curves for each trial and the combined population were reconstructed, and HR estimated. The primary outcome was DFS; OS, pCR, and toxicity were secondary outcomes.ResultsEight trials with 2425 patients were included. Carboplatin improved DFS (HR 0.60; 95% CI 0.47 to 0.78; I² 45%, p < 0.001) compared with AT at trial level and IPD level (HR 0.66; 95%CI, 0.55 to 0.80, p < 0.001) analysis. The OS also improved with carboplatin at both trial level (HR 0.69, 95%CI 0.50 to 0.95, I² 41%, p = 0.02) and IPD level (HR 0.68; 95%CI, 0.54 to 0.87, p = 0.002) analysis. The pCR as expected, was better in the carboplatin arm (OR 2.11; 95% CI = 1.44–3.08; I² 67%, p = 0.009). Anaemia and thrombocytopaenia were higher in the carboplatin arm.Conclusionand relevance: Carboplatin added to (neo)adjuvant chemotherapy in TNBC improves survival, as shown in both trial level and IPD analysis.     

External validation of the PRESTO pediatric tool for predicting in-hospital mortality from traumatic injury

BackgroundBenchmarking is crucial for quality improvement of trauma systems. The Pediatric Resuscitation and Trauma Outcome (PRESTO) model allows risk-adjusted comparisons of in-hospital mortality for pediatric trauma populations in under-resourced environments. Our aim was to validate PRESTO in a high-resource setting using provincial Trauma Registry (TR) data and compare it to the standard benchmarking model, the Injury Severity Score (ISS).MethodsThis retrospective case-control study collected demographic, vital sign, and outcome data from the TR for patients aged <16 years sustaining major trauma from 2013 to 2021. The PRESTO model estimates predicted probability of in-hospital mortality (Pm) using the age, heart rate, blood pressure, oxygen saturation, neurological status, and use of airway supplementation. PRESTO was assessed by comparison of Pm in patients who died and survived and comparison of area under the receiver–operator curve (AUROC) with that of ISS. Statistical analysis was performed using R.ResultsWe included 647 patients, of which 69 died in-hospital (11%). The cohort was 37% female, with a median age of 8 and median ISS of 17. The median Pm for cases was significantly higher compared to controls (1.0 vs. 5.2 × 10⁻⁵, p < 0.001). The AUROC for PRESTO and ISS were not significantly different (0.819 and 0.816, respectively; p = 0.95).ConclusionPRESTO is valid in a resource-rich environment, such as a Canadian province. It performs equally well to ISS but is simpler to derive. In the future, PRESTO may serve to benchmark levels of in-hospital mortality within or across institutions over time across Canada.Level of evidence3     

Evaluation of a biodegradable polyurethane patch for repair of diaphragmatic hernia in a rat model: A pilot study

IntroductionCongenital diaphragmatic hernia (CDH) repair is an area of active research. Large defects requiring patches have a hernia recurrence rate of up to 50%. We designed a biodegradable polyurethane (PU)-based elastic patch that matches the mechanical properties of native diaphragm muscle. We compared the PU patch to a non-biodegradable Gore-Tex™ (polytetrafluoroethylene) patch.MethodsThe biodegradable polyurethane was synthesized from polycaprolactone, hexadiisocyanate and putrescine, and then processed into fibrous PU patches by electrospinning. Rats underwent 4 mm diaphragmatic hernia (DH) creation via laparotomy followed by immediate repair with Gore-Tex™ (n = 6) or PU (n = 6) patches. Six rats underwent sham laparotomy without DH creation/repair. Diaphragm function was evaluated by fluoroscopy at 1 and 4 weeks. At 4 weeks, animals underwent gross inspection for recurrence and histologic evaluation for inflammatory reaction to the patch materials.ResultsThere were no hernia recurrences in either cohort. Gore-Tex™ had limited diaphragm rise compared to sham at 4 weeks (1.3 mm vs 2.9 mm, p = 0.003), but no difference was found between PU and sham (1.7 mm vs 2.9 mm, p = 0.09). There were no differences between PU and Gore-Tex™ at any time point. Both patches formed an inflammatory capsule, with similar thicknesses between cohorts on the abdominal (Gore-Tex™ 0.07 mm vs. PU 0.13 mm, p = 0.39) and thoracic (Gore-Tex™ 0.3 mm vs. PU 0.6 mm, p = 0.09) sides.ConclusionThe biodegradable PU patch allowed for similar diaphragmatic excursion compared to control animals. There were similar inflammatory responses to both patches. Further work is needed to evaluate long-term functional outcomes and further optimize the properties of the novel PU patch in vitro and in vivo.Level of evidenceLevel II, Prospective Comparative Study.     

Preoperative tendon retraction,not smoking,is a risk factor for failure with continuity after rotator cuff repair

BackgroundSmoking is a poor prognostic factor for healing after rotator cuff repair and is associated with inferior results. We hypothesized that smokers would have higher recurrent tear rates and more postoperative myotendinous junction (MTJ) retraction in healed repairs than nonsmokers three months postoperatively.MethodsRotator cuff repairs (RCRs) were retrospectively reviewed over a 2-year period. Patients underwent magnetic resonance imaging (MRI) within 6 months prior to surgery and again at 3 months postoperatively. Seventy-nine patients were included and stratified by smokers versus nonsmokers. Baseline patient demographics, tear characteristics, and surgical factors were collected. Preoperative and postoperative MRIs were assessed to quantify the MTJ position and to establish the recurrent tear rate.ResultsFor the total cohort (nonsmokers, n = 56; smokers, n = 23), significant differences in age, race, and traumatic onset of injury existed between groups. There were no significant differences in recurrent tear between smokers (26%) and nonsmokers (27%), but nonsmokers were more satisfied. For patients with healed RCRs (nonsmokers, n = 41; smokers, n = 17), there were significant differences in race. On univariate analysis, nonsmokers had a significantly more lateral MTJ postoperatively (P = 0.05). On multivariable regression analysis, medialized postoperative MTJ position in healed cuffs was driven only by greater preoperative rotator cuff retraction preoperatively. There were no significant differences in MTJ position based on smoking status for patients with healed RCRs.ConclusionSmoking does not appear to be an independent risk factor for postoperative MTJ retraction in healed RCRs, also known as failure in continuity. Preoperative tear size and retraction play the biggest roles in predicting postoperative MTJ position, regardless of smoking status. There are no significant differences in patient-reported outcomes for patients with healed RCRs, but nonsmokers had more satisfaction following RCR in the total cohort.Level of EvidenceLevel III; Retrospective cohort study; Diagnostic study     

Mortality after tricuspid valve procedures: A 27-year,single-center experience

ObjectiveTo assess mortality after tricuspid valve (TV) surgery in a large single-center patient cohort.MethodsData from 392 TV procedures performed between 1989 and 2015 in 388 adult patients were retrospectively reviewed. The patients were divided into groups according to the type of concomitant procedure, ie, coronary artery bypass grafting (CABG) (TV + CABG group; n = 87), other valve surgery (TV + valve group; n = 240), or an isolated TV procedure with or without another minor procedure (isolated TV group; n = 65), and the era of the operation, ie, 1989-2005 (n = 173) or 2006-2015 (n = 219). Control groups of patients who underwent other valve procedures and/or CABG during the same time periods were used for comparison.ResultsDuring the most recent era, the annual number of TV procedures increased 2.4-fold, mainly for TV + valve procedures (2.8-fold). Within the TV + valve group, a larger proportion of patients had mild-to-moderate tricuspid regurgitation (grade ≤2) compared with the first-time period (P = .001). The TV + CABG group had significantly greater mortality than both the other groups during both time periods, whereas isolated TV procedure had the lowest mortality rates with the exception of the TV + valve group during the most recent era (P = .41). Survival for patients undergoing TV + valve procedures has improved significantly during the last decade (P = .001) and was comparable with that for other valve operations during this period.ConclusionsIn the last decade, TV repair has been performed more frequently and at lower grades of tricuspid regurgitation compared with previously, and mortality after TV procedures has decreased.     

Body image perception,compliance with a prosthesis and cognitive performance in transfemoral amputees

ObjectiveThe aim of the study was to assess mutual associations of body image perception, compliance with the prosthesis and cognitive performance in transfemoral amputees.MethodsFourty transfemoral amputee (30 male and 10 female), who had a traumatic and unilateral amputation were included in this study. The mean age of the patients at the time of study was 37 ± 9.9 and the mean age at amputation was 12.6 ± 9.4 years. Patients's body image perception and compliance with the prosthesis paramaters were evaluated with Amputee Body Image Scale (ABIS) and Trinity Amputation and Prosthesis Experience Scales (TAPES). MoCA (The Montreal Cognitive Assessment) has been used to determine the cognitive ability of the participant. All tests has been administered by dual task method during ambulation. Patients who had neurologic or cognitive deficit were excluded from the study.ResultsThere was a statistically significant relationship between an individual's body image perception and cognitive performance. Body image perception was significantly and negatively correlated with the MoCA score (r = −0.514, p < 0.001). There was a statistically significant positive correlation between psychosocial adjustment, prosthesis satisfaction and MoCA scores (r = 0.550, p < 0.001).ConclusionsBody image satisfaction, psychosocial adjustment, lack of activity restriction, and satisfaction with prosthesis are positively associated with cognitive performance of transfemoral amputees. Before beginning the amputee rehabilitation programs, we recommend to include not only physical functions, but also consider body image and cognitive functions as assessment parameters.Level of evidenceLevel IV, Diagnostic Study.     

A systematic review and meta-analysis of BRCA1/2 mutation for predicting the effect of platinum-based chemotherapy in triple-negative breast cancer

IntroductionPlatinum-based chemotherapy (PBC) remains the mainstay of treatments for triple-negative breast cancer (TNBC). TNBC is a heterogeneous group, the issue of whether BRCA1/2 mutation carriers have a particular sensitivity to platinum agents is inconclusive. We conducted a meta-analysis to explore the relationship between BRCA1/2 mutation and PBC susceptibility in individuals with TNBC, aiming to gain more information on the size of the benefit of PBC in BRCA1/2 mutation carriers.Materials and methodsAll studies applying PBC with a subgroup of BRCA1/2 status were included. All endpoints, including pCR and RCB in the neoadjuvant phase, DFS in the adjuvant phase, ORR, PFS, and OS in the advanced phase, were assessed using HRs and 95% Cl.ResultsFrom the 22 studies included, there were 2158 patients with TNBC, with 392 (18%) bearing the BRCA1/2 gene mutation. Based on 13 studies applying neoadjuvant PBC, we discovered that BRCA1/2 mutation was substantially associated with a 17.6% increased pCR rate (HR 1.32, 95% CI 1.17–1.49, p < 0.00001; I² = 51%). Same result was observed in RCB0/I index (HR 1.38, 95% CI 1.08–1.76, P = 0.009; I² = 0%). The meta-analysis of 6 trials addressing advanced therapy revealed that ORR rates were significantly higher in patients with BRCA1/2 mutation (HR 1.91, 95% CI 1.48–2.47, p < 0.00001; I² = 32%), as well as PFS(HR 1.13, 95% CI 0.81–1.57, P = 0.47; I² = 0%) and OS (HR 1.89, 95% CI 1.22–2.92, P = 0.004; I² = 0%).ConclusionAccording to our meta-analysis of 22 trials in TNBC, BRCA1/2 mutation carriers were significantly more sensitive to PBC regimens, especially in neoadjuvant and advanced therapy.     

Long-Term Esthetic Outcome of Different Treatment Modalities for Nontuberculous Mycobacterial Cervicofacial Lymphadenitis

BackgroundNontuberculous mycobacterial (NTM) cervicofacial lymphadenitis is a rare infection which almost exclusively occurs in children, most commonly children 0–5 years old. It can leave scars in highly visible areas. The present study aimed to evaluate the long-term esthetic outcome of different treatment modalities for NTM cervicofacial lymphadenitis.MethodsThis retrospective cohort study included 92 participants with a history of bacteriologically proven NTM cervicofacial lymphadenitis. All patients were diagnosed at least 10 years prior and were aged >12 years upon enrollment. Based on standardized photographs, the scars were assessed by subjects with the Patient Scar Assessment Scale, and by five independent observers with the revised and weighted Observer Scar Assessment Scale.ResultsThe mean age at initial presentation was 3,9 years and the mean follow-up time was 15.24 years. Initial treatments included surgical treatment (n = 53), antibiotic treatment (n = 29) and watchful waiting (n = 10). Subsequent surgery was performed in two patients, due to a recurrence after initial surgical treatment, and in 10 patients initially treated with antibiotic treatment or watchful waiting. Esthetic outcomes were statistically significantly better with initial surgery, compared to initial non-surgical treatment, based on patient scores of scar thickness, and based on observer scores of scar thickness, surface appearance, general appearance and the revised and weighted sum score of all assessment items.ConclusionsThe long-term esthetic outcome of surgical treatment was superior to non-surgical treatment. These findings could facilitate the process of shared decision making.Level of EvidenceLevel III
