雾化吸入布地奈德治疗AECOPD合并2型糖尿病患者疗效及对肺通气功能和糖代谢的影响

目的分析雾化吸入布地奈德治疗慢性阻塞性肺疾病急性加重(AECOPD)合并2型糖尿病(T2DM)患者疗效及对肺通气功能和糖代谢指标的影响。 方法选择四川大学华西医院2019年1月至2020年5月诊治的120例AECOPD合并T2DM患者作为对象，根据非随机临床同期对照研究及患者自愿原则分为对照组58例和观察组62例，其中对照组给予低剂量布地奈德治疗，观察组给予高剂量布地奈德治疗。比较两组患者治疗前后肺通气功能、糖代谢指标和炎性因子水平变化，并评估疗效和安全性。 结果两组患者治疗有效率比较无显著差异(P>0.05)；与治疗前比，两组患者治疗后肺通气功能指标均显著升高，但观察组较对照组升高更为显著(P<0.05)；两组患者之间及其治疗前后糖代谢指标均无显著差异(P>0.05)；与治疗前比，两组患者治疗后炎症因子水平均显著降低，但观察组较对照组降低更为显著(P<0.05)；两组不良反应发生率比较无统计学意义(P>0.05)。 结论布地奈德雾化吸入治疗AECOPD合并T2DM安全有效，对糖代谢指标无明显影响，但高剂量的布地奈德对于患者肺通气功能和炎症水平改善效果更好。     

Oesophageal carcinoma with solitary patellar metastasis: a rare case report

The incidence of tumours found in the patella, including primary and metastatic tumours, is low. Solitary metastasis of oesophageal carcinoma (OC) in the patella is even rarer. A 50-year-old man presented to our clinic because of pain and limited range of motion in the right knee for 4 hours and after a fall. On the basis of the patient’s medical history, he was diagnosed with OC 2 months previously and underwent two cycles of paclitaxel liposome combined with tiggio chemotherapy (oral tiggio, 40 mg, two times/day, with a treatment cycle of 3 weeks). A 99mTc-methylene diphosphonate bone scintigraphy scan showed increased radioactivity in the right patella. A right knee biopsy showed the presence of patellar metastasis from OC. Unfortunately, the patient denied additional treatment and was discharged for personal reasons. At the 1-month follow-up, which was conducted by a telephone survey, we learned that the patient had died of acute pulmonary embolism. X-rays and computed tomography are useful for diagnosing patellar metastases, but 99mTc-methylene diphosphonate bone scintigraphy can help physicians diagnose patellar metastasis of OC more rapidly. Biopsy with pathology is the gold standard for diagnosing patellar metastases. Additionally, timely surgical treatment prolongs the survival time of these patients.

Mortality prediction in chronic obstructive pulmonary disease and obstructive sleep apnea

BackgroundWe aimed to assess mortality in chronic obstructive pulmonary disease (COPD), obstructive sleep apnea (OSA), and overlap syndrome, and evaluate which polysomnographic indices—apnea-hypopnea index (AHI) or hypoxemic load measurements—better predict mortality within 10 years.MethodsAdults with symptoms suggestive of sleep apnea and airway disease who underwent both polysomnography and spirometry plus bronchodilator response tests between 2000 and 2018 were included and divided into four groups according to presence of COPD and moderate-to-severe OSA (AHI ≥15/h). We estimated mortality using a Cox model adjusted for demographic/anthropometric covariates and comorbidities; this was called clinical model. To evaluate prognostic performance, we compared the concordance index (C-index) between clinical model and extended models, which incorporated one of polysomnographic indices—AHI, sleep time spent with SpO₂ < 90% (TS90), and mean and lowest SpO₂.ResultsAmong 355 participants, patients with COPD alone (57/355, 16.1%) and COPD–OSA overlap syndrome (37/355, 10.4%) had increased all-cause mortality than those who had neither disease (152/355, 42.8%) (adjusted HR, 2.98 and 3.19, respectively). The C-indices of extended models with TS90 (%) and mean SpO₂ were significantly higher than that of clinical model (0.765 vs. 0.737 and 0.756 vs. 0.737, respectively; all P < 0.05); however, the C-index of extended model with AHI was not (0.739 vs. 0.737; P = 0.15).ConclusionsIn this cohort with symptoms of sleep apnea and airway disease, patients with overlap syndrome had increased mortality, but not higher than in those with COPD alone. The measurement of hypoxemic load, not AHI, better predicted mortality.     

Very fast-progressive pulmonary opacities and high inflammatory factors levels are associated with decease of young Coronavirus Disease 2019 patients

We aimed to retrospectively analyze the clinical and computed tomography (CT) characteristics of young adults with Coronavirus Disease 2019 (COVID-19) pneumonia who were critically ill and to identify the features associated with non-survival.Thirty-eight COVID-19 patients (20–45 years old, 28 men) who had been admitted in the intensive care unit were included, including 18 non-survivors (group 1) and 20 survivors (group 2). Their clinical characteristics and initial and follow-up CT were compared between groups.In group 1, the days from illness onset to death were 21.1 ± 10.3 days; 7 patients had underlying comorbidities. At admission, group 1 exhibited higher serum ferritin and interleukin-6 (IL-6) levels (1142.6 ± 242.4 mg/L and 33.8 ± 18.6 mmol/L) compared with group 2 (728.3 ± 150.9 mg/L and 15.2 ± 6.9 mmol/L, P < .01). Group 1 exhibited more rapidly progressive opacities and consolidation in follow-up CT (16.7 ± 3.1 scores, 15.7 ± 3.1 segments) than group 2 (11.4 ± 4.0 scores, 10.3 ± 4.6 segments, P < .01). The oxygenation index was lower (87.6 ± 19.2 vs 99.1 ± 20.4 mm Hg) and the mechanical ventilation duration was longer (14.7 ± 6.9 vs 9.7 ± 3.7 days) in group 1 compare with group 2 (P < .01).Compared with the survivors, the non-survivors showed higher serum ferritin and IL-6 levels, more rapidly progressive opacities in CT, lower oxygenation index, and longer mechanical ventilation durations. Special attention to ferritin/IL-6 levels and oxygenation index as well as early CT application and timely reexaminations are important to identify the individuals who may be at risk of becoming critically ill.
