Analysis of factors related to postoperative pulmonary infection in lung cancer patients after recovery from COVID-19

Objective:To explore factors related to postoperative pulmonary infection in lung cancer patients after recovery from COVID-19 and to provide methods for preventing and reducing the incidence of postoperative lung infection in patients with lung cancer.Methods:A total of 92 patients who underwent lung cancer surgery in the Department of Thoracic and Cardiac Surgery of Yichang Central People’s Hospital from January 28,2023,to March 3,2023,were selected.They were divided into a pulmonary infection group(47 cases)and a nonpulmonary infection group(45 cases)according to whether pulmonary infection occurred.General clinical data of patients were collected and collated to analyse the related influencing factors of pulmonary infection in lung cancer patients after recovery from COVID-19.Results:Univariate analysis showed that patient age(≥60 years),fever after COVID-19 infection,oral and laryngeal symptoms,digestive tract symptoms,neurological symptoms,long-term smoking history,hypertension history,and operation time(≥3 h)were correlated with pulmonary infection(all P<0.05).There was no significant correlation between postoperative pulmonary infection and sex,ocular,nasal and tongue symptoms,systemic symptoms,duration of COVID-19,COPD,lobectomy site,incision pain,mechanical ventilation time(≥6 h),drainage tube retention time(3 d),surgical method(P>0.05).Logistic multivariate analysis showed that age(≥60 years old),long operation time(≥3 h)and long-term smoking history were independent influencing factors for postoperative pulmonary infection in patients with radical resection of lung cancer(P>0.05).Conclusion:In this study,older age(≥60 years old),long-term smoking history,and long operation time(≥3 h)were risk factors for pulmonary infection after lung cancer surgery.In the future,active treatment measures can be taken to address these risk factors during the perioperative period to reduce the incidence of postoperative pulmonary infection.

Interpretations and comments for expert consensus on the diagnosis and treatment of heat stroke in China

Heat stroke is the most severe type of heat illness,it is often accompanied by severe multiorgan damage and has a high fatality rate.In January 2020,based on new research evidence and the experiences of Chinese experts in heat stroke,the Expert Group of Heat Stroke Prevention and Treatment of the Chinese People’s Liberation Army(PLA)and the Professional Committee of Critical Care Medicine of the Chinese PLA jointly issued a new Expert Consensus on the Diagnosis and Treatment of Heat Stroke in China.This article aims to interpret and supplement the major updates to the new consensus.

Effects of green bonds on bioenergy development under climate change: A case study in Taiwan province, China

Bioenergy development improves energy security and mitigates climate change.Because the stable supply of agricultural resources provides a solid basis for efficient bioenergy production,the climate-induced impacts such as changes in lempeniture and precipitation that potentially alter the farming decisions and cropping patterns should be taken into account.This study designs two-stage stochastic programming with recourse model to investigate the net bioenergy production and emission reduction,as well as the bioenergy producers'strategies under various market operations and climate scenarios.The results show that the net production of biopower and biofuel are relatively stable because the supply of bioenergy feedstocks could remain at a constant level,but the farming decisions,cropping pattern,and resource utilization are likely to be altered by climate-induced impacts.The results also indicate that for efficient bioenergy production,approximately 41.5 billion TWD(9.65 billion CNY)and 33.6 billion TWD(7.81 billion CNY)of bond principal should be invested in crop-based and residual-based technology,respectively.In the face of strict environmental regulations and emission management,biopower technology becomes more competitive,and under such a circumstance,more than 98.3%of the low-cost bond should be invested in biopower development to achieve development efficiency.
