RESUMO
Objective To conduct a retrospective cohort study on the influencing factors of poor prognosis of young and middle-aged patients with pulmonary tuberculosis. Methods Selecting 426 young and middle-aged patients who were diagnosed with pulmonary tuberculosis in our hospital from January to December 2018 as the research subjects. Collecting the social demography information of all patients and the information of potential factors affecting the prognosis (allergy history, smoking history, drinking history, BMI level, disease information, treatment information, etc.) and discussing the factors affecting the prognosis of young and middle-aged pulmonary tuberculosis patients and their effects. Results The average age of 426 patients was (41.93±5.17) years old, the average BMI of them was (21.97±3.15) kg/m2, and an average course of disease of them was (2.76±0.99) years. There was no significant difference in the basic sexual information between men and women. In this study, a total of 128 patients with poor prognosis were retrospectively followed up, including 90 males and 38 females. The detection rate of males was significantly higher than that of females (χ2=16.976, P2=18.850, P2=38.924, P2=127.207, P2=32.566, P2=16.715, P2=17.315, P2=16.976，P1 and P1 and P<0.05; Regular treatment still showed potential protective factors, with an HR of 0.408, P<0.05. Conclusion: Male, emaciated body type, disease course ≥ 5 years, smoking history, number of lung field lesions ≥ 3, presence of pulmonary cavities and comorbidities are potential risk factors, while regular treatment suggests potential protective factors. Conclusion More targeted disease control and management should be implemented for middle-aged and young patients with pulmonary tuberculosis based on the aforementioned influencing factors to improve their prognosis.
RESUMO
BackgroundTo clarify the characteristic and the duration of positive nucleic acid in children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including asymptomatic children. MethodsA total of 32 children confirmed with SARS-CoV-2 infection between January 24 and February 12, 2020 from four provinces in Western China were enrolled in this study and followed up until discharge and quarantine 14 days later. ResultsEleven children (34%) were asymptomatic, among whom six children had normal computed tomographic (CT) scan images. Age and gender were not associated with clinical symptoms or the results of CT scan in children infected with SARS-CoV-2. The concentrations of white blood cells and neutrophils were higher in children with asymptomatic infection than in children with clinical symptoms or CT abnormalities. Patients who presented with CT abnormalities had lower D-dimer or lower total bilirubin than those who had normal CT scan but clinical symptoms. All children recovered and no one died or was admitted to the pediatric intensive care unit (PICU). The mean duration of positive SARS-CoV-2 nucleic acid was 15.4 (SD=7.2) days and similar for both asymptomatic children and children with symptoms or CT abnormalities. We found a significant negative correlation between the lymphocyte count and the duration of positive nucleic acid test. ConclusionsChildren with asymptomatic infection should be quarantined for the same duration as symptomatic patients infected with SARS-CoV-2. The clinical significance and mechanism behind the negative correlation between the number of lymphocytes and the duration of positive SARS-CoV-2 needs further study.
RESUMO
Objective To explore the diagnostic value of CD4 cell count and IL-6/IL-10 ratio in combination for the diagnosis of AIDS complicated with Pneumocystis pneumonia. Methods A total of 100 AIDS patients with pneumocystis pneumonia admitted to the Nanchong Central Hospital from January 2018 to May 2019 were enrolled in the AIDS pneumonia group, 100 AIDS patients were enrolled in the AIDS group, and 100 healthy subjects were included in the control group. The number of CD4+T cells in serum was detected by flow cytometry, and the expression levels of IL-6 and IL-10 in serum were detected by enzyme-linked immunosorbent assay. The AUC of receiver operating characteristic curve (ROC) was used to analyze the CD4 cell count and the diagnostic significance of IL-6/IL-10 detection in AIDS with pneumocystis pneumonia. Results The number of CD4 cells in the serum of AIDS patients with Pneumocystis pneumonia was significantly lower than that of AIDS patients and healthy subjects (t=28.31, P<0.0001; t=36.90, P<0.0001), but the ratio of IL-6/IL-10 was higher than that of AIDS patients and healthy individuals (t=7.184, P<0.0001; t=19.03, P<0.0001). The sensitivity of CD4 cell count and IL-6/IL-10 ratio in the diagnosis of AIDS patients with Pneumocystis pneumonia was 92.00%, the specificity was 88.00%, and the accuracy was 89.33%. Conclusion The detection of CD4 cell count and IL-6/IL-10 ratio can be used as a potential marker for the diagnosis of AIDS with Pneumocystis pneumonia.
RESUMO
BACKGROUND:Autologous hematopoietic stem celltransplantation is an effective treatment for multiple myeloma. After chemotherapy, autologous hematopoietic stem celltransplantation becomes a standard therapeutic regimen for multipla myeloma, and numerous units and centers have reported that. How to reduce toxic and adverse reactions of the drugs, transplantation-related complications and improvement of long-term survival have been present foci. OBJECTIVE:To summarize the new progress of autologous hematopoietic stem celltransplantation in the treatment of multiple myeloma. METHODS:We retrieved PubMed and China National Knowledge Infrastructure database, Vip database, Wanfang database, free medicaljournals.com source for articles published from January 2006 to November 2012 concerning autologous hematopoietic stem celltransplantation in the treatment of multiple myeloma. The key words were“autologous hematopoietic stem celltransplantation, multiple myeloma”. A total of 46 articles were included. RESULTS AND CONCLUSION: Large-dose chemotherapy combined with autologous hematopoietic stem celltransplantation for multiple myeloma obtained better outcomes compared with the traditional chemotherapy. However, many patients could not relieve after single autologous hematopoietic stem celltransplantation, and the disease recurred final y. Al ogeneic hematopoietic stem celltransplantation was limited by donor source, and treatment-associated fatality rate was high, so its use was confined. Therefore, present new development direction included twice autologous hematopoietic stem celltransplantation, autologous transplantation combined with al ogeneic transplantation with reduced-intensity conditioning regimens as wel as drug on the basis of single autologous hematopoietic stem celltransplantation. Novel drug proteasomes inhibitor and immunomodulator in inducer remission, pretreatment and sustaining stages obviously improved total reaction rate of multiple myeloma therapy and long-term survival.
