Background: The impact of local management of pulmonary metastases on the disease course of patients with metastatic colorectal cancer is poorly assessed., Methods: REPULCO database was a retrospective cohort on 18 years that included all patients treated for lung metastases from colorectal cancer who received local and/or systemic treatments., Aims: Primary objective was overall survival, secondary were progression-free survival and survival without chemotherapy., Results: Three hundred and fifteen patients were analyzed, 157 with only systemic treatments, 78 with only local treatments, and 80 with local and systemic treatments. Overall survival at 5 years was 26.9% (IC95%: [17.7-36.9]) for systemic treatments only, 61.0% (IC95%: [40.8-76.1]) for local treatments only, and 77.8% (IC95%: [60.1-88.3]) for local and systemic treatments. Progression-free survival at 2 years was 4.8% (IC95%: [2.1-9.2]) for systemic treatment only, 28.3% (IC95%: [17.7-39.9]) for local treatments only, and 21.8% (IC95%: [13.1-31.9]) for local and systemic treatments. Median survival without chemotherapy was 2.99 months (IC95%: [2.33-3.68]) for systemic treatments, 33.97 months (IC95%: [19.06-NA]) for local treatments, and 12.85 months (IC95%: [8.18-21.06]) for local and systemic treatments., Conclusion: Local treatments of lung metastasis led to prolonged survival and allowed long periods of time without chemotherapy in this cohort., Competing Interests: Conflict of interest The authors declare no conflict of interest., (Copyright © 2024.

Objectives: Evaluate theoretical and practical training of thoracic surgeons-in-training in robotic-assisted thoracic surgery (RATS) in France., Methods: A survey was distributed to thoracic surgeons-in-training in France from November 2022 to February 2023., Results: We recruited 101 thoracic surgeons-in-training (77% response rate). Over half had access to a surgical robotics system at their current institution. Most (74%) considered robotic surgery training essential, 90% had attended a robotic procedure. Only 18% had performed a complete thoracic robotic procedure as the main operator. A complete RATS procedure was performed by 42% of fellows and 6% of residents. Of the remaining surgeons, 23% had performed part of a robotic procedure. Theoretical courses and simulation are well developed; 72% of residents and 91% of fellows had undergone simulation training in the operating room, at training facilities, or during congress amounting to <10 h (for 73% of the fellows and residents), 10-20 h (17%), 20-30 h (8%) or >30 h (3%). Access to RATS was ≥1 day/week in 71% of thoracic departments with robotic access. Fellows spent a median of 2 (IQR 1-3) semesters in departments performing robotic surgery. Compared with low-volume centres, trainees at high-volume centres performed significantly more complete robotic procedures (47% vs 13%; P = 0.001), as did fellows compared with residents., Conclusions: Few young surgeons perform complete thoracic robotic procedures during practical training, and access remains centre dependent. Opportunities increase with seniority and exposure; however, increasing availability of robotic devices, theoretical formation, and simulation courses will increase opportunities., (© The Author(s) 2024.

Objectives: To determine safety and survival outcomes associated with lobectomy, segmentectomy and wedge resection for early-stage lung cancer by quiring the French population-based registry EPIdemiology in THORacic surgery (EPITHOR)., Methods: Retrospective analysis of 19 452 patients with stage c IA lung carcinoma who underwent lobectomy, segmentectomy or wedge resection between 2016 and 2022 with curative-intent. Main outcome measures were 90-day mortality and 5-year overall survival estimates. Proportional hazards regression and propensity score matching were used to adjust outcomes for key patient, tumour and practice environment factors., Results: The treatment distribution was 72.2% for lobectomy, 21.5% for segmentectomy and 6.3% for wedge. Unadjusted 90-day mortality rates were 1.6%, 1.2% and 1.1%, respectively (P = 0.10). Unadjusted 5-year overall survival estimates were 80%, 78% and 70%, with significant inter-group survival curves differences (P < 0.0001). Multivariable proportional hazards regression showed that wedge was associated with worse overall survival [adjusted hazard ratio (AHR), 1.23 (95% confidence interval 1.03-1.47); P = 0.021] compared with lobectomy, while no significant difference was disclosed when comparing segmentectomy to lobectomy (1.08 [0.97-1.20]; P = 0.162). The three-way propensity score analyses confirmed similar 90-day mortality rate for wedge resection and segmentectomy compared with lobectomy (hazard ratio: 0.43; 95% confidence interval 0.16-1.11; P = 0.081 and 0.99; 0.48-2.10; P = 0.998, respectively), but poorer overall survival (1.45; 1.13-1.86; P = 0.003 and 1.31; 1-1.71; P = 0.048, respectively)., Conclusions: Wedge resection was associated with comparable 90-day mortality but lower overall survival when compared to lobectomy. Overall, all types of sublobar resections may not offer equivalent oncologic effectiveness in real-world settings., (© The Author(s) 2024.

Aims: Pulmonary hypertension (PH) is characterised by an increase in pulmonary arterial pressure, ultimately leading to right ventricular failure and death. We have previously shown that nerve growth factor (NGF) plays a critical role in PH. Our objectives here were to determine whether NGF controls Connexin-43 (Cx43) expression and function in the pulmonary arterial smooth muscle, and whether this mechanism contributes to NGF-induced pulmonary artery hyperreactivity., Methods and Results: NGF activates its TrkA receptor to increase Cx43 expression, phosphorylation, and localization at the plasma membrane in human pulmonary arterial smooth muscle cells, thus leading to enhanced activity of Cx43-dependent GAP junctions as shown by Lucifer Yellow dye assay transfer and fluorescence recovery after photobleaching -FRAP- experiments. Using both in vitro pharmacological and in vivo SiRNA approaches, we demonstrate that NGF-dependent increase in Cx43 expression and activity in the rat pulmonary circulation causes pulmonary artery hyperreactivity. We also show that, in a rat model of PH induced by chronic hypoxia, in vivo blockade of NGF or of its TrkA receptor significantly reduces Cx43 increased pulmonary arterial expression induced by chronic hypoxia and displays preventive effects on pulmonary arterial pressure increase and right heart hypertrophy., Conclusions: Modulation of Cx43 by NGF in pulmonary arterial smooth muscle cells contributes to NGF-induced alterations of pulmonary artery reactivity. Since NGF and its TrkA receptor play a role in vivo in Cx43 increased expression in PH induced by chronic hypoxia, these NGF/Cx43-dependent mechanisms may therefore play a significant role in human PH pathophysiology., Competing Interests: Declaration of Competing Interest The authors have no competing interests to declare., (Copyright © 2024 The Authors.

Objectives: To assess the current practice of pulmonary metastasectomy at 15 European Centres. Short- and long-term outcomes were analysed., Methods: Retrospective analysis on patients ≥18 years who underwent curative-intent pulmonary metastasectomy (January 2010 to December 2018). Data were collected on a purpose-built database (REDCap). Exclusion criteria were: previous lung/extrapulmonary metastasectomy, pneumonectomy, non-curative intent and evidence of extrapulmonary recurrence at the time of lung surgery., Results: A total of 1647 patients [mean age 59.5 (standard deviation; SD = 13.1) years; 56.8% males] were included. The most common primary tumour was colorectal adenocarcinoma. The mean disease-free interval was 3.4 (SD = 3.9) years. Relevant comorbidities were observed in 53.8% patients, with a higher prevalence of metabolic disorders (32.3%). Video-assisted thoracic surgery was the chosen approach in 54.9% cases. Wedge resections were the most common operation (67.1%). Lymph node dissection was carried out in 41.4% cases. The median number of resected lesions was 1 (interquartile range 25-75% = 1-2), ranging from 1 to 57. The mean size of the metastases was 18.2 (SD = 14.1) mm, with a mean negative resection margin of 8.9 (SD = 9.4) mm. A R0 resection of all lung metastases was achieved in 95.7% cases. Thirty-day postoperative morbidity was 14.5%, with the most frequent complication being respiratory failure (5.6%). Thirty-day mortality was 0.4%. Five-year overall survival and recurrence-free survival were 62.0% and 29.6%, respectively., Conclusions: Pulmonary metastasectomy is a low-risk procedure that provides satisfactory oncological outcomes and patient survival. Further research should aim at clarifying the many controversial aspects of its daily clinical practice., (© The Author(s) 2024.

Background: The RAPID [Renal (urea level), Age, Pleural fluid purulence, source of Infection and Denutrition (albumin level)] score classifies patients with pleural infection according to mortality risk at 3 months. This study aims to assess the applicability of this score in a thoracic surgery department and to determine the impact of surgery in the management of pleural infection depending on the Rapid score., Methods: In this single center retrospective study, patients managed for pleural infection, from January 1st 2013 to June 30th 2019, were included. The primary endpoint was the probability of survival at 6 months and 12 months depending on the RAPID score. Secondary endpoint was the probability of survival at 6 and 12 months in patients who had surgeries (surgical treatment group) and patients who didn't have surgery (medical treatment group)., Results: Seventy-four patients were included, with a median age of 54.5 years. According to the RAPID score, the low-, medium- and high-risk groups had 30, 30 and 14 patients respectively. The probability of survival at 6 and 12 months in the low- and medium-risk groups were both 0.967 [95% confidence index (CI95): 0.905-1] whereas, the probabilities of survival at 6 and 12 months in the high-risk group was significantly lower at 0.571 (CI95: 0.363-0.899) and 0.357 (CI95: 0.177-0.721) respectively (P<0.0001). The probabilities of survival at 6 months and 12 months in the medical treatment group was 0.875 (CI95: 0.786-0.974) and 0.812 (CI95: 0.704-0.931) respectively compared to the surgical treatment group where probabilities of survival at 6 and 12 months were both 0.923 (CI95: 0.826-1) (P=0.26)., Conclusions: In our study, patients with pleural infection, classified as high-risk according to the RAPID score, had a lower survival rate compared to low- and medium-risk patients. No difference in survival rate was found between patients classified as low- and medium-risk. In selected patients, surgical management seems to decrease mortality compared to exclusive medical management: this result should be confirmed in larger prospective studies., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-22-1599/coif).

Background: Hepaticojejunostomy (HJ) is the gold standard procedure for repairing major bile duct injury (BDI). Dilation status of the BD before repair has not been assessed as a risk factor for anastomotic stricture., Method: This retrospective single-centre study was performed on a population of 87 patients with BDI repaired by HJ between 2007 and 2021. Dilation status was assessed preoperatively, and dilation was defined as the presence of visible peripheral intrahepatic BDs with remaining BD diameter > 8 mm. The short- and long-term outcomes of HJ were assessed according to preoperative dilation status., Results: Before final repair, the BDs were dilated (dBD) in 56.3% of patients and not dilated (ND) in 43.7%. Patients with ND at the time of repair had more severe BDI injury than those with dBD (94.7% vs. 77.6%, p = 0.026). The rate of preoperative cholangitis was lower in patients with ND than in those with dBD (10.5% vs. 44.9%, p = 0.001). The rate of short-term morbidity after HJ was 33.3% (ND vs. dBD: 38.8% vs. 26.3%, p = 0.32). Long-term anastomotic stricture rate was 5.7% with a mean follow-up period of 61.3 months. There were no differences in long-term biliary complications according to dilation status (ND vs. dBD: 12.2% vs. 10.5%, p = 1)., Conclusion: Dilation status of the BD before HJ for BDI seemed to have no impact on short- or long-term outcomes. Both surgical and radiological external biliary drainages after BDI appear to be acceptable options to reduce cholangitis before repair without increasing risk for long-term anastomotic stricture., (© 2023.

Purpose: The most frequent postoperative complication in autologous cranioplasty (AC) is infection. European recommendations include osseous sampling before cryogenic storage of a bone flap. We evaluated the clinical impact of this sampling., Methods: All patients who underwent decompressive craniectomy (DC) and AC in our center between November 2010 and September 2021 were reviewed. The main outcome was the rate of reoperation for infection of the cranioplasty. We evaluated risk factors for bone flap infection, rate of reoperation for any reason (hematoma, skin erosion, cosmetic request, or bone resorption), and radiological evidence of bone flap resorption., Results: A total of 195 patients with a median age of 50 (interquartile range: 38.0-57.0) years underwent DC and AC between 2010 and 2021. Of the 195 bone flaps, 54 (27.7%) had a positive culture, including 48 (88.9%) with Cutibacterium acnes. Of the 14 patients who underwent reoperation for bone flap re-removal for infection, 5 and 9 had positive and negative bacteriological cultures, respectively. Of patients who did not have bone flap infection, 49 and 132 had positive and negative bacteriological cultures, respectively. There were no significant differences between patients with and without positive bacteriological culture of bone flaps in the rates of late bone necrosis and reoperation for bone flap infection., Conclusions: A positive culture of intraoperative osseous sampling during DC is not associated with a higher risk of re-intervention after AC., (Copyright © 2023 Elsevier Masson SAS.

We aimed to describe the clinical outcomes of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) therapy in our institution considering clinical context and pH at cannulation. All patients treated by VA-ECMO during the 2005-2020 period with 1 year complete follow-up were included. Our cohort was divided in three groups according to the pH level at cannulation: pH <7 (group 1), pH 7-7.2 (group 2), and pH>7.2 (group 3). Survival was analyzed using Kaplan-Meier method. Association between pH group and survival was estimated using a Cox model. A total of 572 patients were included: 60 patients in group 1, 115 in group 2, and 397 in group 3. Refractory cardiogenic shock (36%) was the main indication. One year survival rates were 13%, 36%, and 43% in groups 1, 2, and 3, respectively ( p < 0.001). Death mainly occurred within the first month. The strong correlation between pH and lactates led to propose a simple "three seven rule": pH <7 and lactate >7 was associated with <7% survival. Veno-arterial extracorporeal membrane oxygenation should be considered with caution in patients with pH <7. Lactates and pH might be important parameters to elaborate a new score to predict survival in this population. The "three seven rule" can be very relevant when facing emergency situations., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © ASAIO 2023.)

Treatment of metastatic non-small cell lung cancer (mNSCLC) has been modified due to the development of immunotherapy. We assessed survival outcomes (overall [OS] and progression-free [rwPFS] survivals, time-to-next-treatment [TNT]) in mNSCLC patients after first-line immunotherapy and chemotherapy in real-life settings. Association between rwPFS and TNT, two candidate surrogate endpoints (SE), with OS was assessed. This retrospective multi-center study uses data from patients included in the Epidemio-Strategy Medico-Economic program with mNSCLC over 2015-2019. The impact of treatment on rwPFS/OS was evaluated with Cox models. Individual-level associations between SE and OS were estimated with an iterative multiple imputation approach and joint survival models. The population included 5294 patients (63 years median age). Median OS in immunotherapy group was 16.4 months (95%CI [14.1-NR]) and was higher than in chemotherapy group (11.6 months; 95%CI [11.0-12.2]). Improved OS was observed for the immunotherapy group after 3 months for subjects with performance status 0-1 (HR = 0.59; 95%CI [0.42-0.83], p < 0.01). The associations between rwPFS and TNT with OS were close ([Formula: see text]=0.57). Results emphasized a survival improvement with immunotherapy for patients in good health condition. There was moderate evidence of individual-level association between candidate SE and OS., (© 2023. The Author(s).)

Objective: Most brain biopsies are performed using the frame-based stereotactic technique and several studies describe the time taken and rate of complications, often allowing an early discharge. In comparison, neuronavigation-assisted biopsies are performed under general anesthesia and their complications have been poorly described. We examined the complication rate and determined which patients will worsen clinically., Methods: All adults who underwent a neuronavigation-assisted brain biopsy for a supratentorial lesion from Jan, 2015, to Jan, 2021, in the Neurosurgical Department of the University Hospital Center of Bordeaux, France, were analyzed retrospectively in accordance with the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) statement. The primary outcome of interest was short-term (7 days) clinical deterioration. The secondary outcome of interest was the complication rate., Results: The study included 240 patients. The median postoperative Glasgow score was 15. Thirty patients (12.6 %) showed acute postoperative clinical worsening, including 14 (5.8 %) with permanent neurological worsening. The median delay was 22 h after the intervention. We examined several clinical combinations that allowed early postoperative discharge. A preoperative Glasgow prognostic score of 15, Charlson Comorbidity Index ≤ 3, preoperative World Health Organization Performance Status ≤ 1, and no preoperative anticoagulation or antiplatelet treatment predicted postoperative worsening (negative predictive value, 96.3 %)., Conclusion: Optical neuronavigation-assisted brain biopsies might require longer postoperative observation than frame-based biopsies. Based on strict preoperative clinical criteria, we consider to plan postoperative observation for 24 h a sufficient hospital stay for patients who undergo these brain biopsies., Competing Interests: Conflict of Interest Disclosures No author received support from any organization for this study or has financial relationships with any organization that might have an interest in the submitted work., (Copyright © 2023 Elsevier B.V.

Infection of SARS-CoV-2 among health workers (HWs) in contact with cancer patients has been a major issue since the beginning of the pandemic. We aimed to assess the serological immune status of SARS-CoV-2 infection among these HWs. A prospective cohort study was initiated in the comprehensive cancer center of the Nouvelle-Aquitaine region (NA, France). Volunteer HWs working on March 2020 without active infection or symptoms of COVID-19 completed a self-questionnaire and had a blood test at inclusion, at 3 and 12 months. Positive serological status of SARS-CoV-2 infection was defined by anti-nucleocapsid antibodies and/or IgG anti-spike antibodies, except at 12 months due to vaccine. Half of the HWs were included (N = 517) and 89% were followed for three months (N = 500) and one year (N = 462). Seroprevalence of SARS-CoV-2 infection was 3.5% (95% CI: 1.9-5.1), 6.2% (95% CI: 4.1-8.3), and 10% (95% CI: 7.2-12.7) on June-September 2020, September 2020-January 2021, and June-October 2021, respectively. At 12 months, 93.3% had detectable antibodies with 80% vaccinated in the first three months of vaccine availability. The COVID-19-free policy of the institution, respect for barrier gestures, high and early vaccination of HWs, and low prevalence of SARS-CoV-2 in NA may explain the low rate of seropositivity among the HWs of the Institut Bergonié.

Objectives: A lung transplant is the final treatment option for end-stage lung disease. We evaluated the individual risk of 1-year mortality at each stage of the lung transplant process., Methods: This study was a retrospective analysis of patients undergoing bilateral lung transplants between January 2014 and December 2019 in 3 French academic centres. Patients were randomly divided into development and validation cohorts. Three multivariable logistic regression models of 1-year mortality were applied (i) at recipient registration, (ii) the graft allocation and (iii) after the operation. The 1-year mortality was predicted for individual patients assigned to 3 risk groups at time points A to C., Results: The study population consisted of 478 patients with a mean (standard deviation) age of 49.0 (14.3) years. The 1-year mortality rate was 23.0%. There were no significant differences in patient characteristics between the development (n = 319) and validation (n = 159) cohorts. The models analysed recipient, donor and intraoperative variables. The discriminatory power (area under the receiver operating characteristic curve) was 0.67 (0.62-0.73), 0.70 (0.63-0.77) and 0.82 (0.77-0.88), respectively, in the development cohort and 0.74 (0.64-0.85), 0.76 (0.66-0.86) and 0.87 (0.79 - 0.95), respectively, in the validation cohort. Survival rates were significantly different among the low- (< 15%), intermediate- (15%-45%) and high-risk (> 45%) groups in both cohorts., Conclusions: Risk prediction models allow estimation of the 1-year mortality risk of individual patients during the lung transplant process. These models may help caregivers identify high-risk patients at times A to C and reduce the risk at subsequent time points., (© The Author(s) 2023.

The incidence of campylobacteriosis has substantially increased over the past decade, notably in France. Secondary localizations complicating invasive infections are poorly described. We aimed to describe vascular infection or endocarditis caused by Campylobacter spp. We included 57 patients from a nationwide 5-year retrospective study on Campylobacter spp. bacteremia conducted in France; 44 patients had vascular infections, 12 had endocarditis, and 1 had both conditions. Campylobacter fetus was the most frequently involved species (83%). Antibiotic treatment involved a β-lactam monotherapy (54%) or was combined with a fluoroquinolone or an aminoglycoside (44%). The mortality rate was 25%. Relapse occurred in 8% of cases and was associated with delayed initiation of an efficient antimicrobial therapy after the first symptoms, diabetes, and coexistence of an osteoarticular location. Cardiovascular Campylobacter spp. infections are associated with a high mortality rate. Systematically searching for those localizations in cases of C. fetus bacteremia may be warranted.

Background: Surgical rib fixation for multiple rib fractures and flail chest has become more common in the 2000s with interesting results in selected patients. However, surgical rib fixation lacks a consensus on the delay to surgery and the benefits on postoperative clinical outcomes. Our goal was to determine if delay to surgery can affect postoperative outcomes., Methods: We analyzed a retrospective database including all consecutive patients referred for surgical rib fixation. All outcomes were explored according to trauma mechanism, associated lesions, initial ventilatory status, delay to surgery, surgical technique and a specific focus was made towards post-operative care and pulmonary complications. Logistic regressions were performed to evaluate the association between delay to surgery [before 48 hours (early group), 48 hours to 7 days (mid group), more than 7 days (late group)] and pneumonia and failure of extubating., Results: From 2010 to 2020, 159 patients underwent surgical rib fixation. The median hospital length of stay was 18 days (interquartile range, 13-30 days). Pulmonary infections were encountered in 67 patients (42.2%) with about two third of early pneumonia (<5 days). The one-month mortality rate was 1.9%. Delay to surgery was not associated with either pneumonia (P>0.05) or failure of extubating (P>0.05)., Conclusions: Surgical rib fixation can be delayed without increasing the risk of pulmonary complications. Stabilizing other clinical situations can be safely prioritized if needed. A global evaluation including characteristics of trauma and lung evaluation must be considered before surgical stabilization of rib fracture., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-22-735/coif).

Background: Data on long-term outcomes of the Ross operation in children and young adult patients are limited. The best pulmonary valve substitute for the right ventricular outflow tract reconstruction remains uncertain. This study aimed to assess the outcomes of right ventricular outflow tract reconstruction in the Ross operation in young patients using various pulmonary valve substitutes at a single institution. In addition, a comparison of reintervention rates between patients younger than 18 years and those older than 18 years was performed., Methods: The study assessed all patients (N = 110) who underwent the Ross operation at the University Hospital of Bordeaux, France, between 2004 and 2020., Results: The median follow-up time was 4.2 years, and the median age at operation was 15.9 years. There was no operative mortality and 1 late noncardiac death (0.8%). The overall survival rate at 10 years was 99.2%. The need for right ventricular outflow tract reoperation was lower with the pulmonary homograft compared with the Contegra conduit and Freestyle bioprosthesis: 94.3%, 93.8%, and 80% at 5 years, respectively, and 94.3%, 72.3%, and 34.3% at 10 years, respectively ( P  = 0.011). The probability of reintervention was not significantly different at 10 years among children vs adults ( P  = 0.22)., Conclusions: The Ross procedure in children and young adults was associated with a lower requirement for right ventricular outflow tract reoperation when pulmonary homografts were used instead of xenografts., (© 2022 The Author(s).)

Purpose: Chest wall resections for lung cancer treatment remain difficult to plan using standard 2-dimensional computed tomography. Although virtual reality headsets have been used in many medical contexts, they have not been used in chest wall resection planning., Description: We compared preoperative planning of a chest wall surgical resection for lung cancer treatment between senior and resident surgeons who used an immersive virtual reality device and a 2-dimensional computed tomography., Evaluation: Chest wall resection planning was more accurate when surgeons used virtual reality vs computed tomography analysis (28.6% vs 18.3%, P = .018), and this was particularly true in the resident surgeon group (27.4% vs 8.3%, P = .0025). Predictions regarding the need for chest wall substitutes were also more accurate when they were made using virtual reality vs computed tomography analysis in all groups (96% vs 68.5%, P < .0001). Other studied parameters were not affected by the use of the virtual reality tool., Conclusions: Virtual reality may offer enhanced accuracy for chest wall resection and reconstruction planning for lung cancer treatment., (Copyright © 2022 The Society of Thoracic Surgeons.

Background: Dyspnoea in patients with a para-oesophageal hernia (PEH) occurs in 7% to 32% of cases and is very disabling, especially in elderly patients, and its origin is not well defined. The present study aims to assess the impact of PEH repair on dyspnoea and respiratory function., Methods: From January 2019 to May 2021, all consecutive patients scheduled for PEH repair presenting with a modified Medical Research Council (mMRC) score ≥ 2 for dyspnoea were included. Before and 2 months after surgery, dyspnoea was assessed by both the dyspnoea visual analogue scale (DVAS) and the mMRC scale, as well as pulmonary function tests (PFTs) by plethysmography., Results: All 43 patients that were included had pre- and postoperative dyspnoea assessments and PFTs. Median age was 70 years (range 63-73.5 years), 37 (86%) participants were women, median percentage of the intrathoracic stomach was 59.9% (range 44.2-83.0%), and median length of hospital stay was 3 days (range 3-4 days). After surgery, the DVAS decreased statistically significant (5.6 [4.7-6.7] vs. 3.0 [2.3-4.4], p &lt; 0.001), and 37 (86%) patients had a clinically significant decrease in mMRC score. Absolute forced expiratory volume in one second (FEV1), total lung capacity, and forced vital capacity also statistically significantly increased after surgery by an average of 11.2% (SD 17.9), 5.0% (SD 13.9), and 10.7% (SD 14.6), respectively. Furthermore, from the subgroup analysis, it was identified that patients with a lower preoperative FEV1 were more likely to have improvement in it after surgery. No correlation was found between improvement in dyspnoea and FEV1. There was no correlation between the percentage of intrathoracic stomach and dyspnoea or improvement in PFT parameters., Conclusion: PEH repair improves dyspnoea and FEV1 in a statistically significant manner in a population of patients presenting with dyspnoea. Patients with a low preoperative FEV1 are more likely to have improvement in it after surgery., (© 2022.

Background: Campylobacter spp. bacteremia is a severe infection. A nationwide 5-year retrospective study was conducted to characterize its clinical features and prognostic factors., Methods: The study included patients with Campylobacter spp. bacteremia diagnosed in 37 French hospitals participating in the surveillance network of the National Reference Center for Campylobacters and Helicobacters, from 1 January 2015 to 31 December 2019. The goal was to analyze the effects of a delay of appropriate antibiotic therapy and other risk factors on 30-day mortality rates, antibiotic resistance, patient characteristics, and prognosis according to the Campylobacter species., Results: Among the 592 patients, Campylobacter jejuni and Campylobacter fetus were the most commonly identified species (in 42.9% and 42.6%, respectively). The patients were elderly (median age 68 years), and most had underlying conditions, mainly immunodepression (43.4%), hematologic cancers (25.9%), solid neoplasms (23%), and diabetes (22.3%). C. jejuni and Campylobacter coli were associated with gastrointestinal signs, and C. fetus was associated with secondary localizations. Among the 80 patients (13.5%) with secondary localizations, 12 had endocarditis, 38 vascular, 24 osteoarticular, and 9 ascitic fluid infections. The 30-day mortality rate was 11.7%, and an appropriate antibiotic treatment was independently associated with 30-day survival (odds ratio, 0.47 [95% confidence interval, .24-.93]; P = .03). The median efficient therapy initiation delay was quite short (2 days [interquartile range, 0-4 days]) but it had no significant impact on the 30-day mortality rate (P = .78)., Conclusions: Campylobacter spp. bacteremia mainly occurred in elderly immunocompromised individuals with variable clinical presentations according to the species involved. Appropriate antimicrobial therapy was associated with improved 30-day survival., Competing Interests: Potential conflicts of interest. J. L.

Background: Mitochondrial functions are controlled by genes of both mitochondrial and nuclear DNA. Pathogenic variants affecting any of these are responsible for primary mitochondrial disorders (MIDs), which can be diagnosed during adulthood. Kidney functions are highly dependent on mitochondrial respiration. However, the prevalence of MID-associated nephropathies (MIDANs) is unknown in the adult population. We aimed to address this point and to provide a full characterization of MIDANs in this population., Methods: We retrospectively included for observational study adults (≥16 years of age) with genetically diagnosed MID between 2000 and 2020 in our tertiary care academic centre when they had a chronic kidney disease (CKD) evaluation. MIDANs were ascertained by CKD occurring in MIDs. The phenotypic, biological, histopathological and genotypic characteristics were recorded from the medical charts., Results: We included 80 MID-affected adults and ascertained MIDANs in 28/80 (35%). Kidney diseases under the care of a nephrologist occurred in only 14/28 (50%) of the adults with MIDAN. MIDANs were tubulointerstitial nephropathy in 14/28 patients (50%) and glomerular diseases in 9/28 (32.1%). In adults with MID, MIDAN was negatively associated with higher albumin levels {odds ratio [OR] 0.79 [95% confidence interval (CI) 0.67-0.95]} and vision abnormalities [OR 0.17 (95% CI 0.03-0.94)] and positively associated with hypertension [OR 4.23 (95% CI 1.04-17.17)]., Conclusion: MIDANs are frequent among adult MIDs. They are mostly represented by tubulointerstitial nephropathy or glomerular disease. Vision abnormalities, hypertension and albumin levels were independently associated with MIDANs. Our results pave the way for prospective studies investigating the prevalence of MIDANs among undetermined kidney disease populations., (© The Author(s) 2022.

Background: The management of penetrating thoracic injuries in moribund or unstable patients is clearly described in contrast to that of stable patients, particularly for those with a cardiac box injury. This anatomic location suggests a potentially lethal cardiac injury and requires urgent therapeutic decision making. The present study aims at determining when surgical exploration is beneficial for stable patients presenting with penetrating cardiac box injuries (PCBIs)., Methods: This was a retrospective study of stable civilian patients with PCBI referred to level I trauma centers in the Marseille area between January 2009 and December 2019. Using post hoc analysis of the management outcomes, patients whose surgery was considered therapeutic (group A) were compared with those whose surgery was considered nontherapeutic and with nonoperated patients (group B)., Results: A total of 155 patients with PCBI were included, with 88% (n = 137) of stab wound injuries. Overall, surgical exploration was performed in 54% (n = 83), considered therapeutic in 71% (n = 59), and performed by video-assisted thoracoscopy surgery in 42% (n = 35) with a conversion rates of 14% (n = 5). Initial extended fast assessment with sonography for trauma revealed the presence of hemopericardium in 29% (n = 29) in group A versus 9.5% (n = 7) in group B, p = 0.010, and was associated with a negative predictive value of 93% regarding the presence of a cardiac injury. Chest tube flow was significantly higher in patients who required surgery, with a median (interquartile range) of 600.00 (350.00-1200.00) mL versus 300.0 (150.00-400.00) mL ( p = 0.001)., Conclusion: Extended fast assessment with sonography for trauma and chest tube flow are the cornerstones of the management of stable PCBI. Video-assisted thoracoscopy represents an interesting approach to check intrathoracic wounds while minimizing surgical morbidity., Level of Evidence: Therapeutic/Care Management; Level IV., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Lung cancer screening is correlated with an increase in detection of small indeterminate pulmonary nodules and these nodules often require operative resection to obtain the diagnosis. In suspected early-stage lung cancer, video-assisted thoracoscopic surgery (VATS) has become the preferred option. In this context of minimally invasive surgery, diagnostic wedge resection is sometimes difficult to perform for small deep impalpable nodules. So, our purpose was to determine whether performing VATS for indeterminate pulmonary nodule increases the risk of lobectomy for benign lesions., Methods: A retrospective analysis was carried out in our center from January 2013 to January 2019 on patients who underwent resection for a solitary pulmonary nodule suspicious for cancer. Resection method, frozen section analysis, post-operative outcomes, operative and pathology reports were reviewed., Results: Six hundred fifty-one patients underwent surgical exploration for a solitary pulmonary nodule. Thirty hundred and forty-five patients underwent VATS and 306 patients underwent thoracotomy. Patients in the VATS group underwent significantly more wedge resections (P=0.012) and diagnosis of lung cancer was significantly more frequent in the thoracotomy group (P<0.001). One hundred and thirty-two patients (38.3%) in the VATS group and 60 patients (19.6%) in the thoracotomy group underwent lobectomy without frozen section analysis of the pulmonary nodule. There was no significant difference in terms of lobectomy performed for a benign lesion between the two groups., Conclusions: VATS was associated with a higher rate of benign lesion resection but was not associated with a higher rate of lobectomies for benign lesion in our study., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-21-1789/coif).

Introduction: Telehealth is taking an increasingly important part of medicine. This practice change is being accelerated by the pandemic linked to coronavirus disease 2019. Oncology is a medical specialty for which this paradigm shift is particularly relevant., Methods: We developed a survey aiming at evaluating the use of teleconsultation by physicians managing patients with lung cancer in France. The survey was available online from December 15, 2020, to February 10, 2021., Results: Answers were obtained from 142 clinicians (73.9% pneumologists, 18.3% medical oncologists, and 7.7% with another specialty), 129 (90.8%) of whom had already performed teleconsultation. Among those, 123 (95.3%) started after the coronavirus disease 2019 pandemic. In addition, 72.9% had a moderate usage of this tool (<10 teleconsultations/mo). The frequency of clinicians never using teleconsultation was higher in private practices ( p  = 0.029). The two clinical situations for which teleconsultation was frequently used were visits during treatment without imaging assessment (53.5%) and post-treatment surveillance (80.3%). Depending on the type of treatment received, the frequency of teleconsultation was variable. Lung cancer subtype also affected the clinician's practice. Indeed, 47.2% never proposed this tool for SCLC. Teleconsultation was considered to be of no contribution, a moderate contribution, a significant contribution, or a revolution of the clinical practice for 14.1%, 66.2%, 10.6%, and 2.1% of the respondents, respectively. The participants expected to decrease, stabilize, or increase their teleconsultation activity in 18.3%, 52.8%, and 23.2% of the cases, respectively., Conclusions: Most thoracic oncologists in France are using teleconsultation, mostly as an additional tool that should not replace the doctor-patient in-person relationship., (© 2022 The Authors.)

For patients with locally advanced non-small cell lung cancer invading the spine, induction chemoradiotherapy combined with radical en bloc resection is the key to obtaining long-term survival. With time, our operative technique evolved to a two-step surgery as we experienced numerous perioperative complications during one step surgery. The aim of our study was to assess postoperative morbimortality and long-term survival of both techniques. We retrospectively reviewed all patients who underwent en bloc resection for lung cancer invading the spine between October 2012 and June 2020. Every patient underwent induction therapy. Sixteen patients were included: nine patients were operated on with one step surgery, seven patients were operated on with two step interventions. Twenty-five percent of patients had major perioperative complications and 56.2% of patients had major post-operative complications. Patients in the "one step" group tended to have more perioperative complications whereas patients in the "two step" group tended to have more post-operative complications. Overall 3-year survival was 40% in the one-step and 86% in the two-step surgery group. Although our practice has been improved by two-step interventions, post-operative morbidity remains significant. As long term survivals are encouraging, this type of treatment should still be proposed for highly selected patients, in specialized centers.
