Background: The outbreak of 2019 novel coronavirus disease in Wuhan, China, has spread rapidly worldwide. In the early stage, we encountered a small but meaningful number of patients who were unintentionally scheduled for elective surgeries during the incubation period of COVID-19. We intended to describe their clinical characteristics and outcomes. Methods: We retrospectively analyzed the clinical data of 34 patients underwent elective surgeries during the incubation period of COVID-19 at
Myocardial infarction is one of the primary causes of mortality in patients with coronary heart disease worldwide. Early treatment of acute myocardial infarction restores blood supply of ischemic myocardium and decreases the mortality risk. However, when the interrupted myocardial blood supply is recovered within a certain period of time, it causes more serious damage to the original ischemic myocardium; this is known as myocardial ischemia/reperfusion injury (MIRI). The pathophysiological mechanisms leading to MIRI are associated with oxidative stress, intracellular calcium overload, energy metabolism disorder, apoptosis, endoplasmic reticulum stress, autophagy, pyroptosis, necroptosis and ferroptosis. These interplay with one another and directly or indirectly lead to aggravation of the effect. In the past, apoptosis and autophagy have attracted more attention but necroptosis and ferroptosis also serve key roles. However, the mechanism of MIRI has not been fully elucidated. The present study reviews the mechanisms underlying MIRI. Based on current understanding of the pathophysiological mechanisms of MIRI, the association between cell death-associated signaling pathways were elaborated, providing direction for investigation of novel targets in clinical treatment.
The coronavirus disease 2019 (COVID-19) became a global pandemic. Males, compared to females, seem to be more susceptible to COVID-19, but related evidence is scarce, especially in severe patients. We explored sex differences in clinical characteristics and potential risk factors for mortality in severe COVID-19 patients. In this retrospective cohort study, we included all severe COVID-19 patients admitted to Eastern Renmin Hospital of Wuhan University, Wuhan, China, with a definitive clinical outcome as of Apr 10, 2020. Of the included 651 patients, 332 were male, and 319 were female. Males and females did not differ in age and underlying comorbidities. Males were more likely than females to report fever and develop serious complications, including acute respiratory distress syndrome, secondary infection, acute cardiac injury, coagulopathy, acute kidney injury and arrhythmia. Further, males had much higher mortality relative to females. Multivariable regression showed neutrophilia (odds ratio 6.845, 95% CI 1.227-38.192, p=0.028), thrombocytopenia (19.488, 3.030-25.335, p=0.002), hypersensitive troponin I greater than 0.04 pg/mL (6.058, 1.545-23.755, p=0.010), and procalcitonin greater than 0.1 ng/mL (6.350, 1.396-28.882, p=0.017) on admission were associated with inhospital death. With either of these risk factors, the cumulative survival rate was relatively lower in males than in females. In conclusion, males are more likely than females to develop serious complications and progress to death. The potential risk factors of neutrophilia, thrombocytopenia, hypersensitive troponin I greater than 0.04 pg/mL and procalcitonin more than 0.1 ng/mL may help clinicians to identify patients with poor outcomes at an early stage, especially in males.
Postpartum depression is a disabling mental disorder commonly seen in parturients under trial of labor after cesarean, which causes serious harm to the parturients. The etiology is unclear. We hypothesized that epidural labor analgesia can reduce the incidence rate of postpartum depression. Enrolled multiparas were divided into the epidural labor analgesia group (n = 263) or nonanalgesia group (n = 160) according to their own request. Edinburgh Postnatal Depression Scale was used to assess their mental status at 48 hours and 42 days after delivery. Relative perinatal variables were collected and further analyzed using univariate analysis and multivariate logistic regression analysis to assess the relation of epidural analgesia with the occurrence of postpartum depression under trial of labor after cesarean. The Edinburgh Postnatal Depression Scale score 48 hours ≥ 10 in the no epidural analgesia group was 26.42% while the epidural analgesia group was 8.49% (OR, 0.209; 95% CI, 0.096–0.429; P<0.001). The Edinburgh Postnatal Depression Scale score 42 day ≥ 10 in the no epidural analgesia group was 25.16% while the epidural analgesia group was 6.59% (OR, 0.235; 95% CI, 0.113–0.469; P<0.001). The incidence of postpartum depression was significantly lower in the epidural labor analgesia group at 48 hours and 42 days. There was also a significant relation between the Edinburgh Postnatal Depression Scale scores at 48 hours and 42 days after delivery. Epidural analgesia, discomfort within 42 days, and self-rating anxiety scale are independent predictors of postpartum depression for trial of labor after cesarean in 42 days. Epidural labor analgesia is associated with a decreased risk of postpartum depression. Further study with a large sample size and more centers is needed to evaluate the impact of epidural analgesia on the occurrence of postpartum depression.
