The current organ allocation rules prioritize elderly and urgent patients on the lung transplantation (LT) waiting list. A steady increase in the threshold at which age is taken into consideration for LT has been observed. This retrospective cohort study recruited 166 lung transplant recipients aged ≽ 65 years between January 2016 and October 2020 in the largest LT center in China. In the cohort, subgroups of patients aged 65-70 years (111 recipients, group 65-70) and ≽ 70 years (55 recipients, group ≽ 70) were included. Group D restrictive lung disease was the main indication of a lung transplant in recipients over 65 years. A significantly higher percentage of coronary artery stenosis was observed in the group ≽ 70 (30.9% vs. 14.4% in group 65-70, P = 0.014). ECMO bridging to LT was performed in 5.4% (group 65-70) and 7.3% (group ≽ 70) of patients. Kaplan-Meier estimates showed that recipients with cardiac abnormalities had a significantly increased risk of mortality. After adjusting for potential confounders, cardiac abnormality was shown to be independently associated with the increased risk of post-LT mortality (HR 6.37, P = 0.0060). Our result showed that LT can be performed in candidates with an advanced age and can provide life-extending benefits.

Occupational and environmental exposure can directly cause specific lung diseases, and can also induce autoimmune diseases that can lead to various types of interstitial lung diseases. In recent years, it was discovered that certain occupational and environmental exposure was related to the increased risk of Idiopathic pulmonary fibrosis (IPF) disease and progression, including metal and mineral dust, wood dust, organic dust, asbestos dust, silica dust, cigarette smoke and air pollution. IPF is a chronic progressive fibrotic lung disease of unknown etiology, with a characteristic imaging and histologic pattern called usual interstitial pneumonia. This article is a review based on the correlation and mechanism of occupational and environmental exposure in the pathogenesis and disease progression of IPF to improve the understanding of the disease and promote the formulation of treatment plans.

Neurocritical care (NCC) is not only generally guided by principles of general intensive care, but also directed by specific goals and methods. This review summarizes the common pulmonary diseases and pathophysiology affecting NCC patients and the progress made in strategies of respiratory support in NCC. This review highlights the possible interactions and pathways that have been revealed between neurological injuries and respiratory diseases, including the catecholamine pathway, systemic inflammatory reactions, adrenergic hypersensitivity, and dopaminergic signaling. Pulmonary complications of neurocritical patients include pneumonia, neurological pulmonary edema, and respiratory distress. Specific aspects of respiratory management include prioritizing the protection of the brain, and the goal of respiratory management is to avoid inappropriate blood gas composition levels and intracranial hypertension. Compared with the traditional mode of protective mechanical ventilation with low tidal volume (Vt), high positive end-expiratory pressure (PEEP), and recruitment maneuvers, low PEEP might yield a potential benefit in closing and protecting the lung tissue. Multimodal neuromonitoring can ensure the safety of respiratory maneuvers in clinical and scientific practice. Future studies are required to develop guidelines for respiratory management in NCC.

Objective: The aim of this study was to summarize the clinical and imaging characteristics of post-primary tuberculosis in children, so as to improve the early identification and diagnosis of post-primary tuberculosis. Methods: This was a retrospective study which enrolled children who were admitted to the Department No.2 of Respiratory Medicine, Beijing Children's Hospital Affiliated to Capital Medical University between January 2015 to December 2020 and with a diagnosis of post-primary tuberculosis. Results: A total of 30 patients were enrolled, including 10 males and 20 females. The age on admission were 13.0 (12.0, 13.3) years. Their common symptoms were cough and fever, there were 26 cases (87%) with cough and 23 cases (77%) with fever, but only 4 cases (13%) had other toxic symptoms (night sweat, weakness or weight loss) of tuberculosis other than fever. Blood examination showed that the white blood cell count was (10±3)×10⁹/L, accompanied by elevated proportion of neutrophils (0.69±0.11) and increased level of C-reactive protein (31 (15,81) mg/L). The common radiographic findings of CT were nodular or mass shadow with cavitation (19 cases (63%)), consolidation (13 cases (43%)), bronchogenic spread (12 cases (40%)), hilar or mediastinal lymphadenopathy (5 cases (17%)) in this cohort. The affected locations included the right upper lobe (21 cases (70%)), the left lower lobe (17 cases (57%)) and the right lower lobe (15 cases (50%)). Acid-fast bacillus smears and mycobacterial cultures were attempted for all cases, resulting in 33% (10/30) with smear positivity and 50% (15/30) with culture positivity. Conclusions: Post-primary tuberculosis in children has no specific clinical manifestations. Imaging of chest CT is mainly manifested as nodular shadow with cavitation, consolidation or bronchogenic spread. Accurate identification of post-primary tuberculosis is crucial for preventing the spread and early treatment of tuberculosis.

OBJECTIVE: To construct and validate a nomogram for predicting the risk of secondary peripheral neuropathy in patients with advanced lung cancer. METHODS: The sociodemographic and clinical data of 335 patients with advanced lung cancer admitted to Department of Respiratory, the First Affiliated Hospital of Zhejiang University School of Medicine from May 2020 to May 2021 were retrospectively collected. Pearson correlation analysis, univariate and multivariate logistic regression analyses were used to identify the risk factors of secondary peripheral neuropathy in patients with advanced lung cancer. A nomogram was constructed according to the contribution of each risk factor to secondary peripheral neuropathy, and the receiver operating characteristic (ROC) curve, Calibration curve and clinical decision curve were used to evaluate differentiation, calibration, and the clinical utility of the model. The nomogram was further validated with data from 64 patients with advanced lung cancer admitted between June 2021 and August 2021. RESULTS: The incidences of secondary peripheral neuropathy in two series of patients were 34.93% (117/335) and 40.63% (26/64), respectively. The results showed that drinking history ( OR=3.650, 95% CI: 1.523-8.746), comorbid diabetes ( OR=3.753, 95% CI: 1.396-10.086), chemotherapy ( OR=2.887, 95% CI: 1.046-7.970), targeted therapy ( OR=8.671, 95% CI: 4.107-18.306), immunotherapy ( OR=2.603, 95% CI: 1.337-5.065) and abnormal liver and kidney function ( OR=12.409, 95% CI: 4.739-32.489) were independent risk factors for secondary peripheral neuropathy (all P<0.05). A nomogram was constructed based on the above risk factors. The area under the ROC curve (AUC) of the nomogram for predicting the secondary peripheral neuropathy was 0.913 (95% CI: 0.882-0.944); and sensitivity, specificity, positive and negative predictive values were 85.47%, 81.65%, 71.43% and 91.28%, respectively. The Calibration curve and clinical decision curve showed good calibration and clinical utility. External validation results showed that the AUC was 0.764 (95% CI: 0.638-0.869); and sensitivity, specificity, positive and negative predictive values were 79.28%, 85.79%, 73.25% and 85.82%, respectively. CONCLUSIONS Advanced lung cancer patients have a high risk of secondary peripheral neuropathy after anticancer therapy. Drinking history, comorbid diabetes, chemotherapy, targeted therapy, immunotherapy, abnormal liver and kidney function are independent risk factors. The nomogram prediction model constructed in the study is effective and may be used for the risk assessment of secondary peripheral neuropathy in patients with advanced lung cancer.

Juvenile dermatomyositis (JDM) is an autoimmune disease manifesting as proximal muscle weakness and skin rash and can involve multiple systems and visceral organs. Myositis-specific autoantibodies (MSAs) are highly associated with various complications and prognosis in JDM. Patients with anti-Mi-2 antibodies tend to have good prognosis and typical clinical symptoms. Patients with anti-MDA5 antibodies often have diffuse interstitial lung disease and skin ulcer, with mild symptoms of myositis. Patients with anti-NXP2 antibodies often have calcinosis, and such antibodies are associated with gastrointestinal bleeding and perforation. Patients with anti-TIF1-γ antibodies have diffuse and refractory skin lesions. Anti-SAE antibodies are rarely detected in children, with few reports of such cases. This article reviews the features of clinical phenotypes in JDM children with these five types of MSAs, so as to provide a basis for the clinical treatment and follow-up management of children with JDM.

OBJECTIVE: To investigate the clinical features, radiologic scores and clinically relevant risk factors prognosis of secondary interstitial lung disease (ILD) in patients with systemic lupus erythematosus (SLE). METHODS: In this study, 60 SLE patients in Department of Rheumatology of the First Affiliated Hospital of Baotou Medical College and Taizhou First People's Hospital from January 2015 to March 2019 were retrospectively analyzed. All of those 60 patients with SLE underwent lung high resolution computed tomography (HRCT) examination. We used a 1 ∶1 case-control study. There was a matching of age and gender between the two groups. Thirty patients with SLE related ILD (SLE-ILD) were in the case group, and 30 patients with SLE without ILE (SLE non-ILD) were in the control group. The clinical features, pulmonary function test, radiologic characteristic of SLE patients were collected and were used to analyze SLE-ILD. RESULTS: In this study, we reached the following conclusions: First, there were statistically significant differences in chest tightness/shortness of breath, Raynaud's phenomenon, and Velcro rale between SLE-ILD and SLE non-ILD patients (both P < 0.05); Second, hemoglobin (Hb) and albumin (ALB) in the patients of SLE-ILD had a significant decrease compared with the patients of SLE non-ILD. Blood urea nitrogen (BUN), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) increased in SLE-ILD patients compared with SLE non-ILD patients, the difference had statistical significance (P < 0.05); Third, for SLE-ILD patients, the most common type was non-specific interstitial pneumonia (NSIP), followed by usual interstitial pneumonia and lymphocytic interstitial pneumonia; Fourth, there was no significant difference in clinical-radiology-physiology scores between the different ILD types (P>0.05), similarly, the lung HRCT score and lung function between different ILD types had no significant difference (P>0.05); Fifth, multivariate Logistic regression analysis showed that decreased albumin and chest tightness/shortness of breath might be the risk factor for SLE-ILD. CONCLUSION There are statistically significant differences between the SLE-ILD group and SLE non-ILD group in terms of chest tightness/shortness of breath, Velcro rale and Raynaud's phenomenon. Decreased albumin and chest tightness/shortness of breath in SLE patients should be alerted to the occurrence of ILD. NSIP is the most common manifestation of SLE-ILD.
