ObjectiveTo analyze the clinical features of Legionella-associated cavitary pneumonia, and to explore the diagnosis, treatment planning, and clinical management of patients.MethodsThe data of a patient with severe Legionella-associated cavitary pneumonia were collected and analyzed. Databases including PubMed, Ovid, Wanfang, VIP and Chinese National Knowledge Infrastructure were searched for pertinent literatures, using the keyword "Legionella, lung abscess or cavitary pneumonia" in Chinese and English from Jan. 1990 to Jun. 2019. The related literature was reviewed.ResultsA 60-year-old male patient was admitted to hospital because of fever, cough, and expectoration for five days. On presentation, his temperature was 38.3 °C, and pulmonary auscultation revealed rales on the left side of the lungs. Culture of lower airway secretions obtained by bronchoscopy revealed Legionella pneumophila infection, and serotype 6. Chest computerized tomography showed a consolidation in the left lung and an abscess in the left upper lobe. The patient was discharged from the hospital after three months of anti-Legionella treatment (Mosfloxacin, Azithromycin, etc.). Fifteen manuscripts, including 18 cases, were retrieved from databases. With the addition of our case, a total of 19 cases were analyzed in detail. There were 15 males and four females, aged from 4 months to 73 years old. Most of them (14/19, 73.7%) were accompanied by multiple underlying diseases. Initial empiric antimicrobial therapy failed in 15 (78.9%) cases, and 7 (36.8%) patients required combination therapy. The courses of antimicrobial treatment were from 3 to 49 weeks. All except one patient were fully recovered and discharged from hospital.ConclusionsLegionella pneumonia with pulmonary abscess or cavity is rare and often presents with fever. Pulmonary imaging shows infiltration in the initial, but can be free of cavities or abscesses. Most patients have basic diseases. Severe patients often need to be treated in combination with antibiotics for long periods of time.
ObjectiveTo summary the effect of parenteral nutrition combined with enteral nutrition on patients with severe acute pancreatitis. MethodsThe clinical data of 200 patients with severe acute pancreatitis admitted in our hospital in recent 10 years were retrospectively analyzed. Of which 88 cases were treated by traditional nutritional support therapy (traditional nutrition group), the rest of 112 cases of patients with early parenteral nutrition to later period gradually combined with enteral nutrition comprehensive nutritional support strategy (comprehensive nutrition group). ResultsThe APACHEⅡscores and serum level of C-reactive protein (CRP) of patients in comprehensive nutrition group were significantly lower than patients in traditional nutrition group (P < 0.05), while the serum albumin level was significantly higher than that of traditional nutrition group (P < 0.05). In the incidence of complications and mortality, the average length of stay and total cost of comprehensive nutrition group were significantly lower than patients with traditional nutrition group (P < 0.05), the cure rate was significantly higher than that of traditional nutrition group (P < 0.05). ConclusionThe combination of parenteral nutrition and enteral nutrition of nutrition support model not only can shorten the duration of symptoms but also alleviate the burden of patients and reduce complications and mortality.

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 summarize the blood routine indexes and predictive systems that can predict the severity of acute pancreatitis (AP). MethodThe recent domestic and foreign literatures on the predictive value of blood routine indexes for the severity of AP were reviewed.ResultsFrom the current research results at domestic and foreign, independent blood routine indexes such as red blood cell distribution width, average platelet volume, hematocrit (TCT), platelet (PLT) count, platelet distribution width, percentage of immature granulocytes (IG%), and some blood routine calculation indexes such as neutrophil to lymphocyte ratio (NLR), PLT to lymphocyte ratio (PLR), red blood cell distribution width to PLT ratio (RPR), neutrophil-monocyte product, and so on, all had different predictive value for the severity of AP. In addition, multiple prediction modes such as blood routine indexes combined with some serological indexes or other scoring systems could also be used to predict the severity of AP. In general, the predictive value of the NLR, IG%, and HCT on the severity of AP had been unanimously recognized by researchers. However, the conclusions of related studies on the predictive values of PLT, PLR, and RPR on the severity of AP were still controversial. ConclusionsAt present, there are a variety of blood routine indexes can be used to predict severity of AP, but their predictive values are different. Further researches are still needed.
Aiming at the problem that the small samples of critical disease in clinic may lead to prognostic models with poor performance of overfitting, large prediction error and instability, the long short-term memory transferring algorithm (transLSTM) was proposed. Based on the idea of transfer learning, the algorithm leverages the correlation between diseases to transfer information of different disease prognostic models, constructs the effictive model of target disease of small samples with the aid of large data of related diseases, hence improves the prediction performance and reduces the requirement for target training sample quantity. The transLSTM algorithm firstly uses the related disease samples to pretrain partial model parameters, and then further adjusts the whole network with the target training samples. The testing results on MIMIC-Ⅲ database showed that compared with traditional LSTM classification algorithm, the transLSTM algorithm had 0.02-0.07 higher AUROC and 0.05-0.14 larger AUPRC, while its number of training iterations was only 39%-64% of the traditional algorithm. The results of application on sepsis revealed that the transLSTM model of only 100 training samples had comparable mortality prediction performance to the traditional model of 250 training samples. In small sample situations, the transLSTM algorithm has significant advantages with higher prediciton accuracy and faster training speed. It realizes the application of transfer learning in the prognostic model of critical disease with small samples.
ObjectiveTo analyze the effect of noninvasive positive pressure ventilation (NPPV) on the treatment of severe acute pancreatitis (SAP) combined with lung injury [acute lung injury (ALI)/acute respiratory distress syndrome (ARDS)] in emergency treatment. MethodsFifty-six patients with SAP combined with ALI/ARDS treated between January 2013 and March 2015 were included in our study. Twenty-eight patients who underwent NPPV were designated as the treatment group, while the other 28 patients who did not undergo NPPV were regarded as the control group. Then, we observed patients' blood gas indexes before and three days after treatment. The hospital stay and mortality rate of the two groups were also compared. ResultsBefore treatment, there were no significant differences between the two groups in terms of pH value and arterial partial pressure of oxygen (PaO2) (P>0.05). Three days after treatment, blood pH value of the treatment group and the control group was 7.41±0.07 and 7.34±0.04, respectively, with a significant difference (P＜0.05); the PaO2 value was respectively (60.60±5.11) and (48.40±3.57) mm Hg (1 mm Hg=0.133 kPa), also with a significant difference (P＜0.05). The hospital stay of the treatment group and the control group was (18.22±3.07) and (23.47±3.55) days with a significant difference (P＜0.05); and the six-month mortality was 17% and 32% in the two groups without any significant difference (P>0.05). ConclusionIt is effective to treat patients with severe acute pancreatitis combined with acute lung injury in emergency by noninvasive positive pressure ventilation.
Antimicrobial stewardship (AMS) is an important means to control bacterial resistance. The unique situation of intensive care unit (ICU) poses a challenge to AMS. This article reviews the literature on AMS in the ICU at home and abroad in recent years, and summarizes the related measures of AMS. Effective AMS measures in the ICU include setting up a multidisciplinary AMS team, using rapid microbial diagnosis technology to shorten the time of diagnosis, using non-culture methods to assess the necessity of antimicrobial therapy for patients with suspected sepsis, and evaluating the effectiveness of antimicrobial therapy as early as possible and optimizing it. These initiatives aim to increase the rational use of antimicrobials in ICU, reduce the risk of multidrug-resistant infections, and improve patients’ condition.
ObjectiveTo explore the psychological pressure in Intensive Care Unit (ICU) nurses and the sources of their pressure. MethodWe investigated the ICU nurses in West China Hospital with a self-designed psychological pressure questionnaire from March to September 2013. ResultsThe total stress level of ICU nurses was 2.89±0.86. The top five sources were low salaries and welfare benefits (3.37±0.61), high frequency of night work (3.31±0.88), wide need of knowledge (3.22±0.41), heavy workload (3.20±0.80) and chronic fatigue syndrome (3.19±0.75). ConclusionsGreat psychological pressure exists in ICU nurses. We urgently need effective approaches to relieve the stress of ICU nurses in order to improve the efficiency and quality of nursing service.
