Objective To analyze the clinical features,etiology and prognostic factors of nosocomial candidemia in Beijing Anzhen Hospital.Methods A total of 174 cases of nosocomial candidemia identified during the period from January 2003 to December 2013 in Anzhen Hospital were reviewed retrospectively.The underlying conditions,risk factors,clinical manifestations and outcome were described and analyzed.The prognostic factors were analyzed by both univariate analysis including t-test and Chisquare test,and multivariate regression analysis.Results The 174 patients included 108 (62.1％) males and 66 (37.9％) females.The mean age of patients was 53.9±27.3 years,specifically:＜18 years (31/174,17.8％),18-＜ 65 years (56/174,32.2％),and ≥ 65 years (87/174,50.0％).About one-third (59/174,33.9％) of the patients were treated in ICU,followed by cardiac surgery ward (58/174,33.3％),respiratory medicine ward (21 / 174,12.1％),general surgery ward (14/174,8.0％),neurology ward (7/174,4.0％),vascular surgery (6/174,3.4％),and orthopedic ward (3/174,1.7％).Fever was documented in all cases,including 37.5-37.9 ℃ in 3 (1.7％) cases,38.0-38.9 ℃ in 81 (46.6％) cases,39.0-39.9 ℃ in 85 (48.9％) cases,and ≥ 40.0 ℃ in 5 (2.9％) cases.Increased peripheral blood WBC (＞10×109/L) was reported in 162 (93.1％) cases.The percentage of neutrophils (＞75％) was reported in 166 (95.4％) cases.Thrombocytopenia (＜ 100 × 109/ L) was documented in 24 (13.8％) cases.The most frequently isolated pathogen was C.albicans (99/174,56.9％),followed by C.parapsilosis (37/174,21.3％),C.glabrata (20/174,11.5％),C.krusei (11/174,6.3％),C.tropicalis (4/174,2.3％),and other Candida spp.(3/174,1.7％).The death rate was 50.0％ (87/174).Univariate analysis showed that old age,thrombocytopenia,hypoalbuminemia,renal insufficiency,indwelling urinary catheter were associated with death of candidemia patients.Multivariate analysis showed that hypoalbuminemia,bacterial co-infection,and indwelling urinary catheter were independent risk factors of death in nosocomial candidemia.Conclusions Nosocomial candidemia is more common in the patients treated in ICU and surgery ward.The most common pathogen of nosocomial candidemia is C.albicans associated with high mortality.Old age,hypoalbuminemia,bacterial co-infection,and indwelling urinary catheter are associated with death in nosocomial candidemia.

Objective:To explore the clinical utility of bronchoscopy and transbronchial cryotherapy in children with tracheobronchial tuberculosis (TBTB).Methods:Retrospective study was conducted to collect the clinical data of 10 hospitalized children who underwent bronchoscopy and were diagnosed as TBTB and in the Department of Pediatrics of Peking University First Hospital and the Department of Pediatric Respiratory Medicine of the Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University from January 2011 to October 2019. The clinical characteristics of TBTB in children, and the efficacy and safety of bronchoscopy and transbronchial cryotherapy were summarized through descriptive analysis.Results:The onset age of 10 children (6 males and 4 females) ranged from 1-14 years. The clinical manifestations included fever (8/10), cough (7/10) and hemoptysis (2/10). Purified protein derivative test and interferon-γ release assay were performed in 9 and 10 patients respectively, the results were all positive. Chest CT examination was performed in all patients, and 8 patients had hilar and mediastinal lymphadenopathy. All patients underwent pediatric bronchoscopy in time, in 9 patients bronchus was found to be blocked in varying degrees by granulation tissue and caseous necrosis and in the remaining patient, obvious congestion and edema in bronchial mucosa. The bronchoscopic manifestations included 8 cases of lymph node fistula type, 1 case of granulation proliferative type and 1 case of inflammatory infiltration type. Pathological biopsies were performed in 7 cases, the findings were consistent with the pathological characteristics of tuberculosis. Nine patients were treated by pediatric bronchoscopic intervention, with 8 transbronchial cryotherapy by flexible bronchoscopy, and among them, 2 patients were treated by simultaneous rigid bronchoscopy. After 1-3 times of transbronchial cryotherapy, the blocked bronchial lumina in 8 cases were all recanalized, and the curative effect was significant without any serious complications.Conclusions:Bronchoscopy plays an important role in the diagnosis of TBTB in children and is helpful for its classification. Also, transbronchial cryotherapy has good efficacy and safety for TBTB in children, especially for the granuloproliferative type or lymph node fistula type.

To evaluate the efficacy of adjuvant endocrine therapy (AET) in breast cancer patients with a positive-to-negative switch of hormone receptor status after neoadjuvant chemotherapy (NAC).One hundred and six patients who presented with hormone receptor (HR)-positive breast cancer at diagnosis and turned to HR-negative after NAC during December 2000 and December 2013 in Jiaxing Maternity and Child Health Care Hospital were retrospectively identified. Kaplan-Meier analysis and log-rank test were used for univariate analyses of factors related to disease free survival (DFS) and overall survival (OS). Multivariate analysis was carried out using the Cox proportional hazards model in patients with DFS and OS.All the patients were categorized into two groups on the basis of the administration of AET:61 AET-administered patients (57.5%) and 45 AET-naïve patients (42.5%). After a median follow-up of 68 months (range 14-103 months), human epidermal growth factor receptor 2 (HER-2) status, initial clinical stage, pathological axillary lymph node status and the use of AET were identified as the variables affecting DFS and OS (all<0.05). Patients treated with AET had a significantly improved 5-year DFS rate when compared with that without AET (77.1%53.5%,<0.05). The 5-year OS of AET-administered patients was also better than that of AET-naïve patients (80.9%71.0%,<0.05). Cox regression analysis showed that AET-administered or not was the independent predictor for 5-year DFS (=2.096, 95%:1.081-4.065,<0.05).Patients with HR altered from positive to negative after NAC may still gain benefit from AET.
