5.5mmol/L),persistent metabolic acidosis,or low cardiac output syndrome.Following data were collected in all patients:time to ni- tiation and duration of PD;time point of the recovery of urine output;baseline serum creatinine level(Cr0),rise of Cr(Crl),peak Cr (Cr2),descending Cr(Cr3),recovery of Cr(Cr4);and their corresponding postoperative time points.Results Of the 63 patients,58 (92.1%)required PD.Overall mortality rate was 33.3%(21/63).Patients undergone more complex surgery requiring longer aortic damping time;have higher Cr0,Cr2,Cr3 and longer period of the recovery of Cr and urine output(P6d)was associated with more complicated surgical procedure,higher Cr1 and Cr2,delayed recovery of Cr and urine output after surgery,longer period of low cardiac output syndrome,more dysfunctional organs,longer mechanical ventilation and ICU stay postoperatively(P

Objective An epidemiological investigation was carried out on the first family cluster epidemic of psittacosis in Wuhan to provide scientific basis for the prevention and control of Chlamydia psittacosis. Methods Epidemiological data were collected by field epidemiological investigation methods, and pathogenic testing was carried out by collecting cases, suspected exposed persons, and environmental samples. Results The 2 cases in the same family stared with fever, headache and chills. The first case was treated in 5 medical institutions and hospitalized in 2 of them. The results of metagenomic next-generation sequencing in the bronchoalveolar lavage fluid of the case indicated that it was infected with Chlamydia psittaci. Thirty environmental samples from cases and 3 pigeon farmers homes, 4 throat swabs from family members of pigeon farmers were collected, and 15 environmental samples were positive by real-time fluorescence quantitative polymerase chain reaction, all of which were in the cases' home and neighbor farmers' homes, including 8 pigeon feces smearing samples, 3 pigeon drinking residual water samples, 1 sand and corn eaten by pigeons, 1 tableware surface smearing sample, and 1 sample of external environment of the patient's home. Conclusions The family cluster epidemic of psittacosis was caused by exposure to the external environment contaminated by Chlamydia psittacosis. Poultry breeding should be regulated to prevent the spread of poultry infection to the human world. At the same time, the awareness of medical staff should be raised, and pathogenic testing should be carried out to confirm the diagnosis for avoiding the occurrence of severe cases and death.
