Objective To investigate the prethrombotic state and effect of anticoagulation therapy in patients with chronic obstructive pulmonary disease(COPD) and ventilator-associated pneumonia (VAP)．Methods Forty-six COPD patients were divided into VAP group(25 cases)and non-VAP group (21 cases)．The VAP group were randomly subdivided into two groups：group A(conventional therapy group，n=13)，group B(conventional therapy+anticoagulation therapy group，n=12)．The D-dimer (DD)，fibfinogen(FIB)，pulmonary artery pressure(PAP)and the time of weaning were compared between these groups．Results In the COPD patients，the levels of DD，FIB and PAP were significantly increased in VAP group compared with non-VAP group[(0．50±0．26)mg／L，(3．67 ±0．88) L，(31．71 ± 5．66)mm Hg vs(0．23±0．12)mg／L，(1．56±0．45) L，(15．28 ±2．84)mm Hg，respectively，all Plt; 0．05]．In the COPD patients with VAP，the levels of DD，the content of FIB，PAP and mortality were significantly lower in group B with shorter time of weaning compared with group A[(0．22±0．16)mg／L， (1．56±1．17)g／L，(16．00±2．48)him Hg，8．33％ and(4．00±1．41)d vs(O／41±0．09)mg／L，(3．66± 1．03) L，(28．00±0．85)mm Hg，15．4％ and(10．76±3．35)d，respectively，all Plt;0．05]． Conclusions Prethrombotic state exists in COPD patients with VAP．Aggressive anticoagulation on base of routine therapy，by ameliorating microcireulation，call shorten the time of weaning and reduce the mortalit in these patient
Objective To elucidate the clinical features and treatment of parapneumonic effusions ( PPE) . Methods Ninety-seven patients were analyzed retrospectively in Guangzhou First Municipal People’s Hospital fromJanuary 2004 to July 2008. The data of 54 patients with complicated parapneumonic effusion ( CPPE) and 9 cases with empyema were compared with 49 patients with tuberculosis pleural effusions. Results Of 97 cases, 34 patients with uncomplicated parapneumonic effusion ( UPPE) were treated with antibiotics only, whose hospitalization time was ( 14. 8 ±7. 6) days, and 27 cases were cured ( 79. 4% ) . Of 54 CPPE patients, 42 were treated with antibiotics and pleural space drainage with central venous catheter, whose hospitalization time was ( 21. 7 ±13. 0) days, and 32 were cured ( 76. 2% ) . Another12 CPPE patients were treated with interapleural urokinase and drainage from the chest tube, whose hospitalization time was ( 22. 5 ±9. 3) days, and 8 were cured ( 66. 7% ) . Nine cases with empyema were rinsed the pleural with metronidazole solution, whose hospitalization time was ( 25. 7 ±17. 4) days, and 8 were cured( 89. 0% ) . Compared with the tuberculous pleurisy patients, most CPPE and empyema occurred in middle and old aged patients with an average age of ( 63. 3 ±19. 3) years. Polykaryocyte and lactate dehydrogenase increased significantly. Adenosine deaminase ( ADA) was lt; 45 U/L in most UPPE and empyema patients, but was gt; 45 U/L in 7 cases ( 11% ) . Conclusions UPPE is simple and preferably treated with antibiotics alone. While CPPE and empyema should be drainaged as early as possible, and the low-dose urokinase may be helpful. The level of ADA can not absolutely distinguish parapneumonic effusion from tuberculous pleural effusion.
Hospital incident command system is a series of management systems for emergencies response of hospitals from the United States. Some hospitals in many countries have applied this system, but it has not yet been applied in China. In the process of responding to the coronavirus disease 2019 epidemic, West China Hospital of Sichuan University managed coronavirus disease 2019 patients through a standardized and programmatic model using the concept and framework of hospital incident command system, which included organizing hospital incident management team, carrying out incident action plan, space management, personnel management, material management and information management, in order to carry out standardized and procedural crisis response. This article introduces these management measures of West China Hospital of Sichuan University, aiming to provide a reference for establishing a more complete hospital emergency management system in line with China’s system in the future.
Objective To explore the clinical characteristics of Chlamydia psittaci pneumonia. Methods From January 2020 to March 2023, 21 cases of Psittacosis from the First Affiliated Hospital of Nanjing Medical University were diagnosed via metagenomic next-generation sequencing (mNGS). They were divided into a severe group (n=10) and a non-severe group (n=11) based on diagnostic criteria for severe pneumonia, and the clinical presentation, secondary examination, treatment, and prognosis of the two groups were analyzed retrospectively. Results Among the 21 patients, there were 11 males and 10 females, with a mean age of (51.7±11.6) years. All patients had an acute onset and 12 had a confirmed history of exposure to poultry. The onset of the disease occurred in the autumn and winter seasons in 18 patients. All the patients were suffering from high fevers. Other symptoms included coughing, phlegm, tightness in the chest and fatigue. Laboratory examinations showed that the levels of leukocytes, neutrophil counts, C-reactive protein, procalcitonin, aminotransferase, creatine kinase, lactic dehydrogenase, brain natriuretic peptide precursors and D-dimer were significantly higher in the severe group than those in the non-severe group. Chest CT scans revealed varying levels of consolidation and spot shadowing with peripheral exudate in all patients. The patients in the severe group were more likely to have bilateral lung involvement, bilateral pleural effusion, cavity and mediastinal lymph node enlargement. Eleven patients received tetracycline alone, three received laudanum alone, two received respiratory quinolones alone, and five received a combination of two drugs including tetracycline. Chest CT at clinical follow-up showed absorption of lung lesions. Conclusions Chlamydia psittaci pneumonia usually occurs in the fall and winter, and most patients have a history of contact with poultry. Clinical presentation and imaging are not specified. The technology of mNGS enables early diagnosis of the disease, and neutrophil lymphocyte ratio, neutrophil-lymphocyte ratio and lactic dehydrogenase levels help assess the risk of severe disease.
Objective To verify the association between admission serum phosphate level and short-term (<30 days) mortality of severe pneumonia patients admitted to intensive care unit (ICU) / respiratory intensive care unit (RICU). Methods Severe pneumonia patients admitted to the ICU/RICU of Quanzhou First Hospital Affiliated to Fujian Medical University from November 2019 to September 2021 were included in the study. Serum phosphate was demonstrated as an independent risk factor for short-term mortality of severe pneumonia patients admitted to ICU/RICU by logical analysis and receiver operator characteristic (ROC) curve. The patients were further categorized by serum phosphate concentration to explore the relationship between serum phosphate level and short-term mortality. Results Comparison of baseline indicators at admission between the survival group (n=54) and the non survival group (n=46) revealed that there was significant difference in serum phosphate level [0.9 (0.8, 1.2) mmol/L vs. 1.2 (0.9, 1.5) mmol/L, P<0.05]. Logical analysis showed serum phosphate was an independent risk factor for short-term mortality. ROC curve showed that the prediction ability of serum phosphate was close to pneumonia severity index (PSI). After combining serum phosphate with PSI score, CURB65 score, and sequential organ failure score, the predictive ability of these scores for short-term mortality was improved. Compared with the normophosphatemia group, hyperphosphatemia was found be with significantly higher short-term mortality (85.7% vs. 47.3%, P<0.05), which is absent in hypophosphatemia (25.8%). Conclusions Serum phosphate at admission has a good predictive value on short-term mortality in severe pneumonia patients admitted to the ICU/RICU. Hyperphosphatemia at admission is associated with a higher risk of short-term death.
ObjectiveTo investigate the psychological status and its influencing factors of hospital staff during the outbreak of coronavirus disease 2019 (COVID-19), and provide a reference for psychological intervention strategies for hospital staff in public health emergencies.MethodsIn this cross-sectional study, we investigated the staff of Mianzhu People’s Hospital through an anonymous questionnaire survey sent through WeChat group from February 13th to 18th, 2020, to analyze the psychological situation and influencing factors of the on-the-job staff. SPSS 22.0 software was used for statistical analysis.ResultsAmong the 1 115 staff members who met the inclusion criteria, 951 completed the questionnaire, with a response rate of 85.3%. There were 945 valid questionnaires, with an effective response rate of 84.8%. A total of 224 staff members (23.7%) had mental health problems. Multivariate logistic regression analysis showed that the total scores of social support [odds ratio (OR)=0.869, 95% confidence interval (CI) (0.805, 0.938), P<0.001] and the total scores of stress coping strategies [OR=0.685, 95%CI (0.607, 0.772), P<0.001] were protective factors of psychological status, while having kids [OR=1.607, 95%CI (1.084, 2.382), P=0.018] and the position being logistic worker [OR=2.229, 95%CI (1.326, 3.746), P=0.002] were risk factors of psychological status.ConclusionsDuring the outbreak of COVID-19, mental health problems emerged among the staff of designated medical treatment hospital. When a public health emergency occurs, hospitals and relevant departments should take psychological intervention measures as soon as possible to ensure the work of epidemic prevention and control.
