Abstract

:OBJECTIVE. The purpose of this study was to describe the clinical manifestations and CT features of coronavirus disease (COVID-19) pneumonia in 15 pregnant women and to provide some initial evidence that can be used for guiding treatment of pregnant women with COVID-19 pneumonia. MATERIALS AND METHODS. We reviewed the clinical data and CT examinations of 15 consecutive pregnant women with COVID-19 pneumonia in our hospital from January 20, 2020, to February 10, 2020. A semiquantitative CT scoring system was used to estimate pulmonary involvement and the time course of changes on chest CT. Symptoms and laboratory results were analyzed, treatment experiences were summarized, and clinical outcomes were tracked. RESULTS. Eleven patients had successful delivery (10 cesarean deliveries and one vaginal delivery) during the study period, and four patients were still pregnant (three in the second trimester and one in the third trimester) at the end of the study period. No cases of neonatal asphyxia, neonatal death, stillbirth, or abortion were reported. The most common early finding on chest CT was ground-glass opacity (GGO). With disease progression, crazy paving pattern and consolidations were seen on CT. The abnormalities showed absorptive changes at the end of the study period for all patients. The most common onset symptoms of COVID-19 pneumonia in pregnant women were fever (13/15 patients) and cough (9/15 patients). The most common abnormal laboratory finding was lymphocytopenia (12/15 patients). CT images obtained before and after delivery showed no signs of pneumonia aggravation after delivery. The four patients who were still pregnant at the end of the study period were not treated with antiviral drugs but had achieved good recovery. CONCLUSION. Pregnancy and childbirth did not aggravate the course of symptoms or CT features of COVID-19 pneumonia. All the cases of COVID-19 pneumonia in the pregnant women in our study were the mild type. All the women in this study-some of whom did not receive antiviral drugs-achieved good recovery from COVID-19 pneumonia.

摘要

: 客观。本研究的目的是描述冠状病毒病的临床表现和CT特征 (新型冠状病毒肺炎) 对 15 例孕妇进行肺炎并提供一些初步证据,可用于指导新型冠状病毒肺炎的孕妇肺炎的治疗。材料和方法。回顾性分析我院 2020 年 1 月 20 日至 20 20 年 2 月 10 日收治的 15 例新型冠状病毒肺炎肺炎孕妇的临床及ct检查资料。使用半定量CT评分系统估计肺部受累和胸部CT变化的时间过程。分析症状和实验室检查结果,总结治疗经验,并追踪临床转归。结果。11 例患者在研究期间成功分娩 (10 例剖宫产和 1 例阴道分娩),4 例患者仍妊娠 (3 例在孕中期,1 例在孕晚期) 在研究期结束时。无新生儿窒息、新生儿死亡、死胎、流产病例报告。胸部CT最常见的早期发现是磨玻璃影 (GGO)。随着疾病进展,在CT上看到疯狂的铺路模式和固结。在所有患者的研究结束时,异常显示吸收变化。新型冠状病毒肺炎例孕妇肺炎最常见的发病症状为发热 (13/15 例) 和咳嗽 (9/15 例)。最常见的实验室异常发现是淋巴细胞减少 (12/15 例患者)。分娩前后获得的CT图像显示分娩后无肺炎加重征象。研究结束时仍怀孕的 4 名患者未接受抗病毒药物治疗,但获得了良好的恢复。结论。妊娠和分娩没有加重新型冠状病毒肺炎肺炎的症状或CT特征。本研究孕妇新型冠状病毒肺炎例肺炎均为轻度型。这项研究中的所有女性-其中一些人没有接受抗病毒药物-从新型冠状病毒肺炎肺炎中恢复良好。

METHODS::The antimicrobial functions of neutrophils are facilitated by a defensive armamentarium of proteins stored in granules, and by the formation of neutrophil extracellular traps (NETs). However, the toxic nature of these structures poses a threat to highly vascularized tissues, such as the lungs. Here, we identified a cell-intrinsic program that modified the neutrophil proteome in the circulation and caused the progressive loss of granule content and reduction of the NET-forming capacity. This program was driven by the receptor CXCR2 and by regulators of circadian cycles. As a consequence, lungs were protected from inflammatory injury at times of day or in mouse mutants in which granule content was low. Changes in the proteome, granule content and NET formation also occurred in human neutrophils, and correlated with the incidence and severity of respiratory distress in pneumonia patients. Our findings unveil a 'disarming' strategy of neutrophils that depletes protein stores to reduce the magnitude of inflammation.

METHODS::Pneumonia is a common respiratory infectious disease that involves the inflammation of the pulmonary parenchyma. Periodontal disease is widespread and correlated with pneumonia. However, the relationship between periodontal treatment and clinical infectious outcomes in patients with pneumonia has remained undetermined. The aim of this study was to investigate the association between periodontal treatment and the risk of pneumonia events in the Taiwanese population. A nationwide population-based cohort study was conducted using data from the Taiwanese National Health Insurance Research Database (NHIRD). A total of 49,400 chronic periodontitis patients who received periodontal treatment from 2001 to 2012 were selected. In addition, 49,400 healthy individuals without periodontal diseases were picked randomly from the general population after propensity score matching according to age, gender, monthly income, urbanization, and comorbidities. The Cox proportional hazard regression analysis was adopted to assess the hazard ratio (HR) of pneumonia between the periodontal treatment cohort and the comparison cohort. The average ages of the periodontal treatment and comparison groups were 44.25 ± 14.82 years and 44.15 ± 14.5 years, respectively. The follow up durations were 7.66 and 7.41 years for the periodontal treatment and comparison groups, respectively. We found 2504 and 1922 patients with newly diagnosed pneumonia in the comparison cohort and the periodontal treatment cohort, respectively. The Kaplan-Meier plot revealed that the cumulative incidence of pneumonia was significantly lower over the 12 year follow-up period in the periodontal treatment group (using the log-rank test, p < 0.001). In conclusion, this nationwide population-based study indicated that the patients with periodontal treatment exhibited a significantly lower risk of pneumonia than the general population.

METHODS:OBJECTIVE:To describe the treatment of community-acquired pneumonia (CAP) in children under five years in Tanzania. METHODS:Between January and December 2017, children aged 2-59 months with chest radiography-confirmed CAP were enrolled. The parents were interviewed to collect information on the patients and home-based medication. Clinical information was derived from the patient files. Nasopharyngeal swab and blood samples were collected for isolation of the causative pathogens. Swab samples were analysed by quantitative PCR whereas blood samples were tested using BacT/Alert 3D. RESULTS:Overall, 109 children with CAP were included in this analysis. Provision of care to most children was delayed (median = 4.6 days). A quarter (26.6%) were given unprescribed/leftover antibiotics at home. Only one child had positive bacterial culture. Referrals were associated with nasopharyngeal carriage of Streptococcus pneumoniae (p = 0.003) and Haemophilus influenzae (p = 0.004). Of all admitted children, more than a quarter (n = 29) did not need to be hospitalised and inappropriately received injectable instead of oral antibiotics. CONCLUSION:We found high rates of home treatment, particularly with antibiotics. Appropriate health care was delayed for most children because of home treatment. Efforts are needed at the community level to improve awareness of antimicrobial resistance.
