Relationship Between Preoperative Inflammation Ratios Derived From Preoperative Blood Cell Count and Postoperative Pulmonary Complications in Patients Undergoing Lobectomy: A Single-Center Observational Study.

OBJECTIVE: Evaluation of the association of inflammatory cell ratios, especially neutrophil-to-lymphocyte ratio (NLR), based on preoperative complete blood counts, with postoperative complications in lobectomy surgery. DESIGN: This was a retrospective monocentric cohort study. SETTING: The study was conducted at Foch University Hospital in Suresnes, France. PARTICIPANTS: Patients having undergone a scheduled lobectomy from January 2018 to September 2021. INTERVENTIONS: There were no interventions. MEASUREMENTS AND MAIN RESULTS: The authors studied 208 consecutive patients. Preoperative NLR, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic inflammation index, systemic inflammation response index, and aggregate inflammation systemic index were calculated. Median and (IQR) of NLR was 2.67 (1.92-3.69). No statistically significant association was observed between any index and the occurrence of at least one major postoperative complication, which occurred in 37% of the patients. Median postoperative length of stay was 7 (5-10) days. None of the ratios was associated with prolonged length of stay (LOS), defined as a LOS above the 75th percentile. CONCLUSIONS: The results suggested that simple available inflammatory ratios are not useful for the preoperative identification of patients at risk of postoperative major complications in elective lobectomy surgery.

Perioperative Outcomes During Double-Lung Transplantation and Retransplantation in Cystic Fibrosis Patients: A Monocentric Cohort Study.

OBJECTIVE: Life expectancy for lung-transplant patients, especially those with cystic fibrosis (CF), is leading increasingly to more retransplantations. DESIGN: Retrospective monocentric cohort study. SETTING: Foch University Hospital, Suresnes, France. PARTICIPANTS: CF patients having had a primary double-lung transplantation (pLgTx) or a retransplantation (reLgTx) from 2012 to 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The authors compared the main intraoperative and early postoperative features between pLgTx (n = 258) and reLgTx (n = 24). Demographic characteristics were similar. No patients with retransplantations had a preoperative bridge with extracorporeal membrane oxygenation (ECMO); however, 23 patients had it in the pLgTx group (p = 0.24). Patients with retransplants had longer second graft ischemic time (p = 0.02), larger intraoperative bleeding volume (p = 0.001) and blood transfusion (p = 0.009 for packed red blood cells), increased blood lactate concentrations (p = 0.002), and higher norepinephrine dose at end-surgery (p = 0.001). Extracorporeal membrane oxygenation was used during surgery in 94 patients in the pLgTx group and 12 patients in the reLgTx group (p = 0.39). Extracorporeal membrane oxygenation could not be weaned after surgery in 55 patients in the pLgTx group and 4 in the reLgTx group (p = 0.54). Despite worse preoperative renal function in the reLgTx group (p < 0.001), there was no difference concerning renal replacement therapy in the intensive care unit between groups (p = 0.08). There were no differences between groups concerning the main complications, including primary graft dysfunction. Although the difference was not statistically different (p = 0.17), mortality was 3 times higher in the reLgTx group. CONCLUSIONS: Intraoperative period of retransplantation was more convoluted but had a similar ECMO profile to primary transplantation. In addition, the early postoperative period was similar.

Prevalence, Characteristics and Preoperative Predictors of Chronic Pain After Double-Lung Transplantation: A Prospective Cohort Study.

OBJECTIVE: Data on chronic pain after lung transplantation are heterogeneous. This study prospectively explored the prevalence, characteristics, consequences, and preoperative predictors of pain in lung transplant recipients. DESIGN: A prospective cohort study. SETTING: The Foch University Hospital, Suresnes, France. PARTICIPANTS: Patients registered on the waiting list for double-lung transplantation in the authors' institution from August 2008 to October 2013 and transplanted. INTERVENTIONS: Database prospectively completed in real time during consultations with a pain-certified anesthesiologist before lung transplantation and six months after surgery. MEASUREMENTS AND MAIN RESULTS: The assessments explored pain in three components: physical (intensity, location, neuropathic and sensory qualifications, treatments), mental (anxiety and depression), and quality of life. Seventy-two patients underwent all assessments. The prevalence of six-month postoperative pain was 68.0%. Among patients with pain, 83.3% reported mild average pain and 26.5% had neuropathic pain. All patients who responded to the questionnaire took analgesics frequently, but only 9.1% took opioids. Patients with pain reported higher levels of anxiety (p = 0.02) and depression (p = 0.01). Additionally, they presented with increased difficulty in ambulation (p = 0.03), work (p = 0.02), and sleep (p = 0.02). The maximum level of preoperative pain was an independent risk factor of six-month postoperative pain (p = 0.03). CONCLUSIONS: The authors report a high prevalence of chronic pain with concomitant psychosocial repercussions despite a reported mild intensity. Perioperative measures, such as personalized and detailed management plans, could improve patient satisfaction.

Blood Lactate During Double-Lung Transplantation: A Predictor of Grade-3 Primary Graft Dysfunction.

OBJECTIVE: Many prognostic factors of grade-3 primary graft dysfunction at postoperative day 3 (PGD3-T72) have been reported, but intraoperative blood lactate level has not been studied. The present retrospective study was done to test the hypothesis that intraoperative blood lactate level (BLL) could be a predictor of PGD3-T72 after double-lung transplantation. DESIGN: Retrospective monocentric cohort study. SETTING: Foch University Hospital, Suresnes, France. PARTICIPANTS: Patients having received a double-lung transplantation between 2012 and 2019. Patients transplanted twice during the study period, having undergone a multiorgan transplantation, or cardiopulmonary bypass, and those under preoperative extracorporeal membrane oxygenation, were excluded. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Analysis was performed on a cohort of 449 patients. Seventy-two (16%) patients had a PGD3-T72. Blood lactate level increased throughout surgery to reach a median value of 2.2 (1.6-3.2) mmol/L in the No-PGD3-T72 group and 3.4 (2.3-5.0) mmol/L in the PGD3-T72 group after second lung implantation. The best predictive model for PGD3-T72 was obtained adding a lactate threshold of 2.6 mmol/L at the end of surgery to the clinical model, and the area under the curve was 0.867, with a sensitivity = 76.9% and specificity = 85.4%. Repeated-measures mixed model of BLL during surgery remained significant after adjustment for covariates (F ratio= 4.22, p < 0.001 for interaction). CONCLUSIONS: Blood lactate level increases during surgery and reaches a maximum after the second lung implantation. A value below the threshold of 2.6 mmol/L at the end of surgery has a high negative predictive value for the occurrence of a grade-3 primary graft dysfunction at postoperative day 3.

Intraoperative Implications of the Recipients' Disease for Double-Lung Transplantation.

OBJECTIVES: To compare intraoperative patterns among patients based on their primary pulmonary disease (cystic fibrosis [CF], chronic obstructive pulmonary disease [COPD]/emphysema [CE], and pulmonary fibrosis [PF]) during double- lung transplantation. The following 3 major outcomes were reported: blood transfusion, extracorporeal membrane oxygenation (ECMO) management, and the possibility of immediate extubation at the end of surgery. DESIGN: Retrospective analysis of a prospectively maintained database, including donor and recipient characteristics and intraoperative variables. SETTING: Foch Hospital, Suresnes, France (academic center performing 60-80 lung transplantations per year). PARTICIPANTS: Patients who underwent double- lung transplantation from 2012-2019. Patients with retransplantation, multiorgan transplantation, or surgery performed with cardiopulmonary bypass were excluded. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Two hundred forty-six patients had CF, 117 had CE, and 66 had PF. No patient had primary pulmonary arterial hypertension. Blood transfusion was higher in the CF group than in the other 2 groups (red blood cells [p < 0.001], fresh frozen plasma [p = 0.004]). The CF and CE groups were characterized by a lower intraoperative requirement of ECMO (p = 0.002), and the PF group more frequently required postoperative ECMO (p < 0.001). CF and CE patients were more frequently extubated in the operating room than were PF patients (37.4%, 50.4%, and 13.6%, respectively; p < 0.001). CONCLUSIONS: Intraoperative outcomes differed depending on the initial pathology. Such differences should be taken into account in specific clinical studies and in intraoperative management protocols.

2022 Update of indications and contraindications for lung transplantation in France.

Lung transplantation (LTx) is a steadily expanding field. The considerable developments have been driven over the years by indefatigable work conducted at LTx centers to improve donor and recipient selection, combined with multifaceted efforts to overcome challenges raised by the surgical procedure, perioperative care, and long-term medical complications. One consequence has been a pruning away of contraindications over time, which has, in some ways, complicated the patient selection process. The Francophone Pulmonology Society (Société de Pneumology de Langue Française, SPLF) set up a task force to produce up-to-date working guidelines designed to assist pulmonologists in managing end-stage respiratory insufficiency, determining which patients may be eligible for LTx, and appropriately timing LTx-center referral. The task force examined the most recent literature and evaluated the risk factors that limit patient survival after LTx. Ideally, the objectives of LTx are to prolong life while also improving quality of life. The guidelines developed by the task force apply to a limited resource and are consistent with the ethical principles described below.

Impact of COVID-19 infection in pregnancy and neonates: A case control study.

OBJECTIVE: To evaluate maternal and neonatal outcomes of pregnant women who were infected by COVID-19 during pregnancy. STUDY DESIGN: A Case control retrospective study was conducted in an Obstetrical Department of a west Parisian area during the first year of COVID-19 pandemic. Maternal and neonatal outcomes were compared between a group of women infected by the SARS-CoV-2 virus during pregnancy (March 2020- February 2021) and a control group of women delivering before pandemic. They were matched according to age and parity. Subgroups of SARS-CoV-2 infection occurring before vs after 37 weeks of gestations and symptomatic vs asymptomatic patients were analyzed. The rate of preterm birth, preeclampsia, placental abruption and stillbirth were compared between the year of pandemic and the year before for all deliveries. RESULTS: Maternal and neonatal outcomes were similar. Among the 86 pregnant women with SARS-CoV-2 infection, five were admitted to Hospital (5.8%). One was transferred in intensive care unit for respiratory distress (1.2%). All patients had favorable outcomes. Patients with symptoms had more associated comorbidities (34.5%, n = 20/58, with symptoms, vs 9,1%, n = 2/22, without symptoms, p = 0.023). No differences in preeclampsia, placenta abruption and stillbirth, but less preterm births (4.9%, n = 160/3383 vs 6.2%, n = 209/3235, p = 0.04) were observed between the year of pandemic and the year before. CONCLUSION: There were few complications associated with COVID-19 infection among pregnant patients and their neonates. A low rate of associated comorbidities, a good access to healthcare services in this area and the small sample size of patients could explain these results.

High-Emergency Lung Transplantation for Interstitial Lung Disease Associated With Anti-MDA5 Dermatomyositis: A Case Report.

BACKGROUND: Rapidly progressive interstitial lung disease (RPILD) associated with the anti-melanoma differentiation-associated gene 5 antibody-positive (anti-MDA5ab+) dermatomyositis (DM) is a rare but life-threatening condition despite immunosuppressive treatment. We report the case of a 44-year-old woman who was diagnosed with severe RPILD associated with anti-MDA5ab+ DM 1 week before her admission in the intensive care unit. The patient underwent a successful double-lung transplant after she failed treatment with immunosuppressive therapy, including tofacitinib. At 1-year follow-up, she had experienced no relapse of the disease. CASE REPORT: This case includes a patient recently diagnosed with RPILD for whom no treatment showed efficacy, including glucocorticoids, cyclophosphamide, plasma exchanges, tofacitinib, and tacrolimus. She was placed under mechanical ventilation and venovenous extracorporeal membrane oxygenation 2 weeks after diagnosis in a bridge-to-transplant process. She was successfully transplanted 20 days later after having been registered on the French National Lung Transplant Waiting List with high priority. One year after surgery, her pulmonary function tests were good, and she showed no sign of relapse of anti-MDA5ab+ DM. CONCLUSIONS: Lung transplantation can be a life-saving procedure in RPILD related to anti-MDA5ab+ DM. High-emergency allocation priority on the transplant list reduced the time between diagnosis and surgery. Patients without comorbidities should be promptly referred to specialized centers to rapidly assess the feasibility of transplantation in this context.
