摘要:目的：觀察小兒反復性肺炎的發生與血微量元素的關系。方法:選擇56例反復性肺炎患兒為觀察組，與60例健康兒童作對照，分別測定血鎘、鉛、銅、鋅、鈣、鎂、鐵含量。結果:56例反復性肺炎患兒血鋅、鐵含量較對照組減低，差異有統計學意義（Plt;0.05）。結論:部分反復性肺炎的發生與血微量元素鋅、鐵缺乏有關。應對反復性肺炎患兒常規行血微量元素檢測，對血微量元素缺乏者應予相應補充治療。Abstract: Objective: To observe the relationship to the occurrence of repeated pneumonia and the microelement in blood. Methods: We chose the 56 infant patients who suffered from repeated pneumonia as the observe group while the 60 health infants as the comprise group, then test the content of cadmium， plumbum， cuprum， zinc， calcium， magnesium and ferrum in blood. Results: The content of zinc and ferrum in the patient’s blood was lower than the comparison group, and the P value was Plt;0.01 and Plt;0.05 respectively, there was obvious differentiation between the two groups. Conclusion: Occurence of part repeated pneumonia is related to the deficiency of the microelements zinc and ferrum in blood. We should detect the common content of microelement to the infant patients who suffer the repeated pneumonia, and give a complement treatment to the microelements’ deficiency infant patients.
At present, coronavirus disease 2019 has become the most serious public health emergency in the world. The disease is still spreading around the world. The disease progresses rapidly and is highly contagious, causing great harm to the public health security of the world. Based on the research evidence published at home and abroad, this article systematically summarizes the biological structure of severe acute respiratory syndrome coronavirus 2, and the pathogenesis, transmission routes and susceptible populations, clinical features and treatment methods of coronavirus disease 2019. It aims to help medical workers understand coronavirus disease 2019 in order to better diagnose and treat the disease, and provide references for future research.
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.
Objective To compare the humidification effect of the MR410 humidification system and MR850 humidification system in the process of mechanical ventilation. Methods Sixty-nine patients underwent mechanical ventilation were recruited and randomly assigned to a MR850 group and a MR410 group. The temperature and relative humidity at sites where tracheal intubation or incision, the absolute humidity, the sticky degree of sputum in initial three days after admission were measured. Meanwhile the number of ventilator alarms related to sputum clogging and pipeline water, incidence of ventilator associated pneumonia, duration of mechanical ventilation, and mortality were recorded. Results In the MR850 group,the temperature of inhaled gas was ( 36. 97 ±1. 57) ℃, relative humidity was ( 98. 35 ±1. 32) % , absolute humidity was ( 43. 66 ±1. 15) mg H2O/L, which were more closer to the optimal inhaled gas for human body.The MR850 humidification system was superior to the MR410 humidification system with thinner airway secretions, less pipeline water, fewer ventilator alarms, and shorter duration of mechanical ventilation. There was no significant difference in mortality between two groups. Conclusions Compared with MR410 humidification system, MR850 humidification system is more able to provide better artificial airway humidification and better clinical effect.
Objective Risk factors for real-word immune checkpoint inhibitor-related pneumonitis in patients with lung cancer were analyzed by systematic analysis. Methods Computerized retrieval of PubMed, EMbase, Web of Science, the Cochrane Library , WanFang Data, CNKI and VIP databases was carried out. Studies were collected from the database establishment to March 2023. Three researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. Meta-analysis was performed using RevMan5.4.1software. Results A total of 18 studies were included with a total of 4 990 patients. The results of meta-analysis showed that, interstitial pneumonia [odds ratio (OR)=9.32, 95% confidence interval (CI) 4.66 - 18.67, P<0.01], smoking history (OR=2.39, 95%CI 1.29 - 4.45, P<0.01), chronic obstructive pulmonary disease (COPD) (OR=5.54, 95%CI 2.96 - 10.36, P<0.01), chest radiotherapy (OR=2.74, 95%CI 1.80 - 4.19, P<0.01), pulmonary fibrosis (OR=7.46, 95%CI 4.25 - 13.09, P<0.01), high programmed death ligand 1 (PD-L1) expression (OR=2.98, 95%CI 1.71 - 5.22, P<0.01), high absolute eosinophil count (AEC) (OR=3.92, 95%CI 2.17 - 7.08, P<0.01) and pembrolizumab (OR=2.90, 95%CI 1.56 - 5.37, P<0.01) were independent risk factors for immune checkpoint inhibitor-related pneumonitis in lung cancer patients. Conclusions Interstitial pneumonia, smoking history, COPD, Chest radiotherapy, pulmonary fibrosis, high PD-L1expression, high AEC and pembrolizumab are independent risk factors for immune checkpoint inhibitor-related pneumonitis in lung cancer patients. Due to insufficient evidence on the risk factors of low albumin, more studies are needed to further identify it.
Previous studies have shown that rehabilitation can relieve clinical symptoms, prevent complications, and improve physical function and quality of life in patients with pneumonia. This consensus summarizes the rehabilitation assessment, self-protection, rehabilitation goals, rehabilitation programs, indications for termination of treatment, nutrition support and psychological rehabilitation for patients with mild, moderate, severe and critical types of coronavirus disease 2019 based on the relevant literature and previous practice of coronavirus disease 2019. We hope this consensus can provide a reference for rehabilitation of coronavirus disease 2019.
ObjectiveTo investigate a more convenient and safe sampling method for viral nucleic acid detection of coronavirus disease 2019.MethodsAn oropharyngeal swab and nasopharyngeal swab were simultaneously taken from 100 patients with coronavirus disease 2019 in a hospital in Wuhan. Then the efficacies of two sampling methods were compared on the positive rates of viral nucleic acid detection.ResultsThe positive rate for SARS-CoV-2 was 54% in oropharyngeal swabs, while 89% positive in nasopharyngeal swabs. There was a significant difference in the detection rate between oropharyngeal swab and nasopharyngeal swab (χ2=3.850 4, P=0.049 7).ConclusionsThe positive rate for nucleic acid testing from nasopharyngeal swabs are significantly better than that from oropharyngeal swabs. Therefore, sampling by nasopharyngeal swabs, rather than oropharyngeal swabs, should be chosen as the preferred virological screening method for patients with coronavirus disease 2019.
