Objective To explore the causes and solutions of rehospitalization of the high-risk neonates. Methods The data collection form was designed based on the literature reviewing and the discussion of the nursing quality management team. Results The samples were retrospectively collected from January 2015 to October 2015. There were 106 cases readmitted among the 3012 discharged cases with the ratio of 3.52%. The average interval of readmission were (4.92±4.0) days, most of the cases were readmitted in 7 days after the first discharge with a ratio of 83.95%, the ratio of readmission within 3 days was 38.68%and that was 45.28%for the readmission within 4~7days. For the Preterm infants, the ratio of readmission within 3 days was 21.69%which was higher than that of the full term (16.98%), there was no statistically significant difference between the two groups(chi-square= 1.45, P>1.45). While the ratio of readmission within 7 days for premature infants was 49.06%(52/106), which was higher than that of full term infants [34.91%(37/106)], and there was statistically significant difference between the two groups(chi-square = 5.45, P<0.05). Jaundice was found to be the major reason for unplanned rehospitalization with the ratio of 50.94%. When compared the incidence of readmission contributed by improper feeding between the low birth weigh and normal birth weight infants, there was nostatistical significance (chi-square = 3.58, P>3.58). But when compared between preterm infants and full term, a higher ratio was found in preterm infants (16.04%), and there was statistically significant difference (chi-square = 5.83, P< 0.05). Conclusion One week after discharge was the peak time of readmission.Jaundice was the main factor of readmission. Premature babies were more likely to have readmission due to feeding problems.

Objective To investigate the predictive value of clinical and radiographic features in fungal pathogen identification in immunocompromised patients with pulmonary invasive fungal infection (IFI).Methods All consecutive immunocompromised adult patients with pulmonary IFI in respiratory intensive care unit (ICU)in the First Affiliated Hospital of Xinjiang Medical University were recruited during a 2 year period.All patients met the 2008 European Organization for Research and Treatment of Cancer and Mycoses Study Group (EORTC /MSG) criteria were studied for proved or probable IFI responding to antifungal agents.The data of demographic,clinical and radiographic features,as well as serological test results of the patients were collected.Differences in the clinical and radiographic features of pulmonary IFIs caused by yeasts and molds were compared by χ2 test.A logistic regression model was used to perform discriminant analysis,and the effect of discrimination was assessed for accuracy.Results The study included 143 patients with a probable diagnosis of IFI who had the following risk factors:diabetes mellitus (43.4%),chronic lung disease (32.2%),broad-spectrum antibiotics administration (≥14 days;35.7%),malignancy (23.1%),corticosteroid therapy (≥14 days;23.1%),chronic renal failure and renal replacement therapy (16.1%),and immunological disease (10.5%).Frequent broad-spectrum antibiotics administration was associated with yeast infection (P <0.05 ),while mold infection was associated with chronic lung disease (P <0.05 ) .Yeast was more often isolated from patients with concurrent bacterial infection and on mechanical ventilation (P <0.05 ) . Thoracic high-resolution computed tomography (HRCT)showed the following images:bronchial pneumonia/pulmonary consolidation (53.1%),massive shadowing (29.4%),small nodules (24.5%),large nodules (18.9%),pleural effusion (18.9%),halo sign (14%),and cavity (9.8%).Imaging showed that mold was more common than yeast in patients with pleural and pericardial effusions (P <0.05).Logistic regression modeling showed that broad-spectrum antibiotics administration,prolonged mechanical ventilation,and pleural and pericardial effusions were statistically significant in fungal identification (P <0.05 ),with a predictive accuracy of 77.6%.Conclusions For immunocompromised patients with pulmonary IFI,most of the risk factors ,the main clinical and chest HRCT features did not help to predict the type of fungal pathogen,and yeast but not cryptococcus may be accompanied or colonized.

Objective:To investigate the expression of fibroblast growth factor 7 (FGF7) and related inflammatory factors in the serum of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:A case control study was conducted. The patients with AECOPD admitted to the First Affiliated Hospital of Xinjiang Medical University from November 2016 to January 2020 were enrolled. The patients were divided into mild group [forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ratio (FEV1/FVC) < 0.70, FEV1 percentage in predicted value (FEV1%) ≥ 80%], moderate group (FEV1/FVC < 0.70, 50% ≤ FEV1% < 80%), and severe group (FEV1/FVC < 0.70, 30% ≤ FEV1% < 50%) based on their lung function test results, with 20 patients in each group, and 20 patients with normal pulmonary function who underwent elective non-thoracic surgery such as gastrointestinal surgery and orthopedics surgery in the same period were selected as controls. The demographic data, FEV1/FVC, FEV1%, FVC, maximum mid-expiratory flow percentage in predicted value (MMEF%), 6-minute walking test (6MWT), and St George Respiratory Questionnaire (SGRQ) score were recorded respectively. Serum levels of FGF7, interleukins (IL-6, IL-1β) and tumor necrosis factor-α (TNF-α) were determined by enzyme linked immunosorbent assay (ELISA). Pearson correlation was used to analyze the correlation between TNF-α and lung function.Results:Compared with the normal pulmonary function group, the levels of FEV1/FVC, FEV1%, MMEF% and 6MWT in the mild, moderate and severe groups were significantly decreased, and the SGRQ scores were increased, the indicators continued to deteriorate with the aggravation of the disease, the statistical differences were found between severe group and normal pulmonary function group [FEV1/FVC: 0.39±0.09 vs. 0.81±0.04, FEV1%: (38.80±6.28)% vs. (109.58±13.80)%, MMEF%: (0.34±0.14)% vs. (2.69±0.99)%, 6MWT (m): 279.00±41.61 vs. 402.85±53.97, SGRQ scores: 34.95±6.71 vs. 2.60±2.06, all P < 0.05]. Compared with the normal pulmonary function group, the levels of FGF7 in the mild, moderate and severe groups were significantly lowered (ng/L: 6.31±2.65, 6.10±1.39, 6.64±1.77 vs. 8.29±3.51, all P < 0.05), but no significant difference was found among the mild, moderate and severe groups (all P > 0.05). Compared with the normal pulmonary function group, IL-6 and TNF-α levels were significantly increased in the mild, moderate and severe groups, and TNF-α increased with the aggravation of the disease, the statistical difference was found between severe group and normal pulmonary function group (ng/L: 7.42±2.28 vs. 3.83±0.92, P < 0.05). There was no significant difference in IL-1β level between the normal pulmonary function group and the mild, moderate, severe groups. Correlation analysis showed that TNF-α was negatively correlated with FEV1/FVC and FEV1% ( r values were -0.350 and -0.527, respectively, both P < 0.01). Conclusion:In AECOPD patients, serum FGF7 was decreased, while IL-6 and TNF-α were increased; however, with the aggravation of the disease, there was no significant change in the level of FGF7 in the peripheral blood, but the TNF-α level might be increased, accompanied by severe damage of small airway function.

Objective To evaluate the predictive factors for failure of non-invasive positive pressure ventilation (NIPPV) in immunosuppressed patients with acute respiratory failure (ARF). Methods The clinical data of 118 immuno-deficient patients treated with NIPPV in the respiratory and intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University from January 2012 to August 2017 were retrospectively analyzed. The patients were divided into a non-endotracheal intubation (ETI) group (n = 62) and ETI group (n = 56) according to whether ETI was performed during the hospitalization period or not. Each observed indicator was analyzed by univariate analysis, and factors leading to failure of NIPPV were further analyzed by Logistic regression. Receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of risk factors for failure of NIPPV in immunosuppressed patients with ARF. Results The non-intubation rate for NIPPV in immunosuppressed patients was 50.8% (60/118). Compared with the non-ETI group, the body temperature, pH value in the ETI group were significantly increased, the partial pressure of arterial carbon dioxide (PaCO2) was significantly decreased, the ratio of oxygenation index (PaO2/FiO2) < 100 mmHg (1 mmHg = 0.133 kPa), acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score ≥ 20, and the number of cases requiring catecholamine were significantly increased, the mortality was significantly increased. Multivariate Logistic regression analysis showed that the APACHE Ⅱ score ≥ 20 [odds ratio (OR) = 15.274, 95% confidence internal (95%CI) = 2.175-107.252, χ2= 7.516, 1 = 0.006], PaO2/FiO2< 100 mmHg (OR = 0.075, 95%CI = 0.014-0.408, χ2= 8.968, 1 = 0.003), and need for catecholamine (OR = 35.736, 95%CI = 6.974-183.124, χ2= 18.400, 1 < 0.001) were independent risk factors for failure of NIPPV. ROC curve analysis showed that the APACHE Ⅱ score ≥ 20 and PaO2/FiO2< 100 mmHg could predict failure of NIPPV, the area under ROC curve (AUC) of the APACHE Ⅱ score ≥ 20 was 0.787, the sensitivity was 83.93%, the specificity was 69.35%, the positive predict value (PPV) was 71.21%, the negative predict value (NPV) was 82.69%, the positive likelihood ratio (PLR) was 2.74, the negative likelihood ratio (NLR) was 0.23, and Youden index was 0.53; the AUC of PaO2/FiO2< 100 mmHg was 0.757, the sensitivity was 80.65%, the specificity was 66.07%, the PPV was 68.18%, the NPV was 78.85%, the PLR was 2.38, the NLR was 0.29, and Youden index was 0.47. Conclusions 50.8% of immunocompromised and ARF patients treated with NIPPV did not require ETI, which is independent of the etiology of ARF. APACHE Ⅱ score ≥ 20, PaO2/FiO2<100 mmHg, and the need for catecholamine are predictive factors for failure of NIPPV in immunocompromised patients.

Objective:To investigate the influencing factors of endotracheal intubation and mechanical ventilation (ETI-MV) in patients with acute respiratory distress syndrome (ARDS) caused by viral pneumonia, and to provide evidence for individualized use of ETI-MV.Methods:Patients with ARDS due to viral pneumonia admitted to the respiratory intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed from November 2017 to March 2022. The gender, age, concomitant diseases, clinical symptoms and signs, complications, lab results, ARDS severity, infectious virus type, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), respiratory support methods and prognosis-related variables were collected. Univariate analysis was performed on each factor, and the variables with statistical significance in the univariate analysis were subjected multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive value of each index for the implementation of ETI-MV.Results:A total of 117 patients were enrolled in the study, including 61 patients in the ETI-MV group, and 3 patients (4.9%), 39 patients (63.9%) and 19 patients (31.1%) with mild, moderate and severe ARDS, respectively. There were 56 patients in non-ETI-MV group, and the mild, moderate and severe ARDS cases were 16 cases (28.6%), 38 cases (67.8%) and 2 cases (3.6%), respectively. There was significant difference between the two groups ( P < 0.05). Univariate analysis showed that during 24 hours admitted to RICU, the levels of interleukin-6 [IL-6 (ng/L): 104.0±90.0 vs. 62.4±76.0], oxygenation index [PaO 2/FiO 2 (mmHg, 1 mmHg≈0.133 kPa): 123.9±30.9 vs. 173.6±28.5], the proportion of cases with pulmonary infiltrating opacity distribution range ≥ 3/4 lung fields [85.3% (52/61) vs. 21.5% (12/56)], APACHE Ⅱ score ≥ 16.5 [67.2% (41/61) vs. 42.9% (24/56)], the rate of nosocomial invasive aspergillus infection [14.8% (9/61) vs. 3.6% (2/56)], the percentage of nosocomial bacterial infection [16.4% (10/61) vs. 3.6% (2/56)], and the lowest CD4 + T lymphocyte count in the course of the disease [cells/mm 3: 192.2±35.8 vs. 215.0±58.3] had significant differences between ETI-MV and non-ETI-MV group (all P < 0.05). Multivariate Logistic regression analysis showed that during 24 hours admitted to RICU the distribution range of pulmonary infiltrating opacity ≥ 3/4 the lung fields [odds ratio ( OR) = 12.527, 95% confidence interval (95% CI) = 3.279-47.859, P < 0.001], APACHE Ⅱ score ≥ 16.5 ( OR = 30.604, 95% CI = 4.318-216.932, P = 0.001), PaO 2/FiO 2 ( OR = 0.948, 95% CI = 0.925-0.972, P < 0.001), CD4 + T lymphocytes cell count ( OR = 0.975, 95% CI = 0.955-0.995, P = 0.015), and nosocomial bacterial infection ( OR = 38.338, 95% CI = 1.638-897.158, P = 0.023) were independent risk factors for ETI-MV. The area under the ROC curve (AUC) of ROC showed that PaO 2/FiO 2 had the greatest predictive value for ETI-MV, with AUC of 0.903, sensitivity of 91.1% and specificity of 95.1% in case of cutoff value of 151 mmHg. The AUC of pulmonary infiltrating opacity distribution range was 0.809, the sensitivity of 85.2%, specificity of 78.6% when the cutoff value was ≥ 3/4 lung field. APACHE Ⅱ scores had the lowest predictive value for selecting ETI-MV, with AUC of 0.704, sensitivity of 83.6% and specificity of 57.1% under the cutoff value was 16.5. Conclusions:For patients with ARDS caused by viral pneumonia, PaO 2/FiO 2 is still the classic reference for selecting ETI-MV, however, the distribution range of pulmonary infiltrating opacity and the systemic severity of the disease during 24 hours admitted to the RICU may provide supplemental helpful information to determine whether the patients choose ETI-MV, especially for moderate ARDS.

Objective:To explore the pros and cons of sequential high-flow nasal cannula (HFNC) and non-invasive positive pressure ventilation (NIPPV) immediately following early extubated patients with severe respiratory failure (SRF) due to acute exacerbations of chronic obstructive pulmonary disease (AECOPD), so as to provide evidence for clinical selection of optimal scheme.Methods:Consecutive AECOPD patients admitted to the respiratory intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University from January 2019 to September 2020 were screened for enrollment. Patients were between 40 years old and 85 years old with acute exacerbation of bronchial-pulmonary infection, who received endotracheal intubation mechanical ventilation (ETI-MV) as the initial respiratory support method. The pattern of synchronous intermittent mandatory ventilation (SIMV) was used in the study. The parameters were set as follows: tidal volume (VT) 8 mL/kg, support pressure 10-15 cmH 2O (1 cmH 2O = 0.098 kPa), positive end-expiratory pressure (PEEP) 4-6 cmH 2O and the ratio of inspiratory to expiratory time 1.5-2.5∶1. Under these conditions, the plateau pressure (Pplat) was maintained less than 30 cmH 2O. The minimum fraction of inspired oxygen was adjusted to keep the pulse oxygen saturation no less than 0.92. When the pulmonary infection control window (PIC window) occurred, the subjects were extubated immediately and randomly divided into two groups, with one group receiving HFNC (called HFNC group), the other group receiving NIPPV (called NIPPV group). Patients with failed sequential HFNC or NIPPV underwent tracheal re-intubation. The rate of tracheal re-intubation within 7 days of extubation, complications (such as nose and face crush injury and gastric distension), in-hospital mortality, duration of ETI before PIC window, length of RICU stay and length of hospital stay were compared, respectively. Results:Forty-four patients were enrolled in the study, 20 in the HFNC group and 24 in the NIPPV group. There was no significant difference in the duration of ETI before PIC window between HFNC and NIPPV groups (hours: 95.9±13.1 vs. 91.8±20.4, P > 0.05). The rate of tracheal re-intubation within 7 days in the HFNC group was significantly higher than that in the NIPPV group [35.0% (7/20) vs. 4.2 % (1/24), P < 0.05]. However, the incidence of complication in the HFNC group was significantly lower than that in the NIPPV group [0% (0/20) vs. 25.0% (6/24), P < 0.05]. Compared with the NIPPV group, the in-hospital mortality in the HFNC group was slightly higher [5.0% (1/20) vs. 4.2% (1/24)], the length of RICU stay (days: 19.5±10.8 vs. 15.5±7.2) and the length of hospital stay (days: 27.4±12.2 vs. 23.3±10.9) were slightly longer, without statistical differences (all P > 0.05). Conclusion:For early extubated patients with SRF due to AECOPD, the compliance of sequential HFNC increased and the complications decreased significantly, but the final effect may be worse than sequential NIPPV.

OBJECTIVE: To explore the diagnostic yield of bronchoscopic rapid on-site evaluation (B-ROSE) in patients with severe invasive bronchopulmonary aspergillosis (IBPA) and provide evidence for starting antifungal treatment before microbiological results were available. METHODS: A prospective cohort study was conducted to select patients with severe pneumonia suspected of IBPA admitted to the respiratory intensive care unit (RICU) in the First Affiliated Hospital of Xinjiang Medical University from June 2014 to June 2022, and those who were primarily infected with other pathogens (such as bacteria, Mycobacterium tuberculosis) at admission were excluded. Whether the antifungal treatment was initiated or not on the basis of the bedside B-ROSE, the B-ROSE was administered as soon as possible within 24 hours after admission to RICU. The current international definition of invasive aspergillosis was used as the gold diagnostic standard, the diagnostic accordance rate, the sensitivity and specificity of B-ROSE were calculated respectively, and the receiver operator characteristic curve (ROC curve) was also plotted, to evaluate the predictive value in diagnosing IBPA. RESULTS: A total of 176 patients with severe pneumonia suspected of IBPA were included in the study. According to international diagnostic standards, there were 81 cases of IBPA and 95 cases of non-IBPA. According to the early diagnosis of B-ROSE, there were 89 cases of IBPA and 87 cases of non-IBPA. The diagnostic accordance rate of B-ROSE was 84.09% (148/176), the area under the ROC curve for B-ROSE in diagnosing severe IBPA was 0.844, the 95% confidence interval (95%CI) was 0.782-0.905, the sensitivity was 87.65%, the specificity was 81.05%, the positive predictive value was 79.78%, the negative predictive value was 88.51%, the rate of underdiagnosis was 12.35% (10/81), and the rate of misdiagnosis was 18.95% (18/95). Compared with the true negative group, the proportion of long-term (≥ 14 days) use of glucocorticoid [70.0% (7/10) vs. 9.1% (7/77), P < 0.01] and the proportion of cases with diabetes [40.0% (4/10) vs. 10.4% (8/77), P < 0.05] were significantly higher in the false negative group (underdiagnosis group). However, B-ROSE of both groups showed mucosal bleeding, congestion and edema [100.0% (10/10) vs. 94.8% (73/77), P > 0.05], indicating that acute mucosal inflammation was non-characteristic. Compared with the true positive group, the proportion of long-term (≥ 14 days) use of glucocorticoid in the false positive group (misdiagnosis group) was significantly reduced [33.3% (6/18) vs. 60.6% (43/71), P < 0.05]. The B-ROSE results showed the proportion of cases with mucosal white spots, black plaques and pseudomembrane was significantly reduced [16.7% (3/18) vs. 52.1% (37/71), P < 0.01] in the misdiagnosed group, which suggest that cases of long-term use of glucocorticoid and cases with B-ROSE showing mucosal white spots, black plaques and pseudomembrane were less likely to be misdiagnosed. The main diseases that were easily misdiagnosed as IBPA included pulmonary tuberculosis (38.9%, 7/18), inflammatory lung adenocarcinoma (27.8%, 5/18) and pulmonary vasculitis (16.7%, 3/18). CONCLUSIONS Before obtaining microbiological evidence, B-ROSE can assist in decision-making of early anti-aspergillus treatment for severe IBPA. This method is prompt, simple, and has high accuracy and reliability. If B-ROSE lacks characteristic manifestations, especially for severe pneumonia in patients with long-term use of glucocorticoid or diabetes, attention should be paid to the underdiagnosis of IBPA. Diseases such as lung tuberculosis, inflammatory lung adenocarcinoma and lung vasculitis should be vigilant against misdiagnosis as IBPA.
