Since 2016, the guidelines for the management of adults with hospital-acquired pneumonia (HAP) / ventilator-associated pneumonia (VAP) have been updated in the United States, Europe, and China, respectively. The differences among these guidelines are demonstrated in this paper. The definition of VAP, how to evaluate the effect of anti-infection therapy, and the prevention strategy are controversial. The consensuses contain diagnostic value of respiratory secretions achieved by noninvasive way for VAP and shorter anti-infection course for VAP. Importantly, pathogenic spectrum for HAP in China is different from others, which is essential for clinical practice.
Using gastric tube to replace the esophagus has been widely used in esophagectomy. This surgical method is gradually replacing the traditional stomach reconstruction. Its advantages in the incidence of postoperative complication, the quality of life and the long-time survival in clinic have proved to be true. Although using tubular stomach in esophagectomy has become the consensus of experts, some details still need some further discussing and this technique should be gradually improved in future. In this review, the superiority and the technical progress of gastric tube are introduced, and we predict the future of tubular stomach and discuss the existed problems.
ObjectiveTo explore the superiority of pleural tenting in Ivor-Lewis esophagogastrectomy. MethodsWe prospectively included 200 esophagus cancer patients with Ivor-Lewis esophagogastrectomy in our hospital between 2013 and 2015 year. The patients were allocated into two groups including a trial group and a control group with 100 patients in each group. There were 72 males and 28 females at an average age of 54.76±6.62 years in the trial group and 66 males and 34 females at an average age of 55.72±6.38 years in the control group. In the trial group pleural tenting was used to cover the anastomotic stoma and gastric tube, while in the control group pleural tenting was not used. Postoperative complications after one year, pressure on the level of the anastomotic stoma, and the grade of quality of life were compared between the two groups. ResultNo statistically significant differences were found in preoperative epidemiological and postoperative pathological characteristics, as well as the postoperative complications and the one-year survival rate (P > 0.05). Quality of life was better in the trial group than that of the control group. ConclusionPleural tenting is a simple, safe, and effective technique for improving quality of life of the patients.
Objective To explore the diagnostic and treatment value of computed tomography (CT)-guided embolization coil localization of pulmonary nodules accurately resected under the thoracoscope. Methods Between October 2015 and October 2016, 40 patients with undiagnosed nodules of 15 mm or less were randomly divided into a no localization group (n=20, 11 males and 9 females with an average age of 60.50±8.27 years) or preoperative coil localization group (n=20, 12 males and 8 females with an average age of 61.35±8.47 years). Coils were placed with the distal end deep to the nodule and the superficial end coiled on the visceral pleural surface with subsequent visualization by video-assisted thoracoscopic (VATS). Nodules were removed by VATS wedge excision using endo staplers. The tissue was sent for rapid pathological examination, and the pulmonary nodules with definitive pathology found at the first time could be defined as the exact excision. Results The age, sex, forced expiratory volume in the first second of expiration, nodule size/depth were similar between two groups. The coil group had a higher rate of accurate resection (100.00% vs. 70.00%, P=0.008), less operation time to nodule excision (35.65±3.38 minvs. 44.38±11.53 min,P=0.003), and reduced stapler firings (3.25±0.85vs. 4.44±1.26,P=0.002) with no difference in total costs. Conclusion Preoperative CT-guided coil localization increases the rate of accurate resection.
ObjectiveTo explore the clinical features, etiological characteristics of co-infections in adult patients with rhinovirus pneumonia.MethodsFourty-nine patients admitted to hospitals for rhinovirus pneumonia were enrolled from 8 medical centers in mainland China between August 2016 and August 2018. Multiplex real-time polymerase chain reaction assays for viral detection were implemented to all bronchoalveolar lavage fluid specimens obtained from the patients. The patients were divided into two groups depending on the status of other etiology co-infection (simple rhinovirus pneumonia group, n=24; coinfections group, n=25). The general data were collected, age, gender, underlying diseases, corticosteroids, symptoms, disease severity, imaging manifestations, etiology, whether patients with respiratory failure, mechanical ventilation, whether the application of vasoactive drugs, antibiotics application, hospital mortality rate of the two groups were reviewed and compared in detail.ResultsThirteen patients (26.5%) with rhinovirus pneumonia had no underlying diseases, 8 patients (16.3%) with chronic underlying lung diseases, 6 patients (12.2%) with diabetes mellitus, 10 patients (20.4%) were immunocompromised patients, 16 patients (32.7%) with respiratory failure, and the hospital mortality rate was 8.2% (4/49). Cases with coinfection were remarkably correlated with more cerebrovascular diseases and disturbance of consciousness, higher PSI score and higher ratio of CURB-65 score >1, more respiratory failure and hospital mortality than those of simple rhinovirus pneumonia group (P< 0.05). There were 25 cases (51.0%) with mixed infection, including 18 bacteria (36.7%), 12 viruses (24.5%), 12 (24.5%) fungi (pneumocystis, aspergillus). Enterobacter and Pseudomonas aeruginosa were most frequently identified bacteria in the viral-bacterial group. Four patients with coinfections died.ConclusionsRhinovirus pneumonia in adult patients often has underlying diseases, and is prone to coinfections (bacteria, fungi, and other viruses). The outcome of these patients is always poor.
ObjectivesTo analyze the effect of bronchiectasis (BE) on the clinical characteristics and prognosis of hospitalized patients with community acquired pneumonia (CAP), and to explore the independent risk factors affecting the 30-day mortality. MethodsA national multi-center retrospective study based on the CAP-China network platform. The clinical data of 6056 patients with CAP who were hospitalized in 13 tertiary teaching hospitals in Beijing, Shandong and Yunnan from January 1, 2014 to December 31, 2014 were collected. To compare the differences in clinical characteristics, etiological distribution and treatment prognosis of patients with CAP with bronchiectasis (BE-CAP) and patients without bronchiectasis (non-BE-CAP). Logistic regression analysis was performed to analyze independent risk factors affecting 30-day mortality in hospitalized patients with BE-CAP. ResultsIn the final analysis, 5880 CAP patients were included, and BE-CAP patients accounted for 10.8% (637/5880). Compared with non-BE-CAP patients, more BE-CAP patients were women, and a higher proportion of patients had chronic obstructive pulmonary disease, bronchial asthma, previous history of glucocorticoid inhalation, and a history of CAP within 1 year. BE-CAP patients had more dyspnea and cyanosis, lower arterial partial pressure of oxygen, longer median time to clinical stability (6 d vs. 4 d, P<0.001), and the incidence of respiratory failure was significantly higher than that of non-BE-CAP patients (27.8% vs. 19.7%, P<0.001). Pseudomonas aeruginosa is the most common bacterial infection in BE-CAP patients. Comorbid bronchiectasis has no significant effect on disease severity, total length of hospital stay, and mortality in CAP patients. The 30-day mortality rate of BE-CAP patients was 2.2%. Logistic regression analysis showed that initial treatment failure [odds ratio (OR) 6.675, 95% confidence interval (CI) 4.235-10.523, P<0.001], respiratory failure (OR 5.548, 95%CI 3.681-8.363, P<0.001), blood urea nitrogen>7.0 mmol/L (OR 2.490, 95%CI 1.625-3.815, P<0.001), albumin<35.0 g/L (OR 1.647, 95%CI 1.073-2.529, P=0.022) and CURB-65 score (OR 1.691, 95%CI 1.341-2.133, P<0.001) were independent risk factors for 30-day mortality in BE-CAP patients. ConclusionsBE-CAP patients have more serious hypoxia symptoms and higher incidence of respiratory failure. For BE-CAP patients with failure of initial treatment, complicated with respiratory failure, blood urea nitrogen>7.0 mmol/L, and albumin<35.0 g/L, treatment evaluation should be performed in time to reduce the mortality rate.
