The European Association for Cardio-Thoracic Surgery (EACTS) has recently updated and published the "2024 EACTS guidelines on perioperative medication in adult cardiac surgery". Based on the latest evidence, the guidelines have been updated in multiple aspects including underlying disease management, antithrombotic medication, arrhythmia treatment and other supportive care, etc. This paper aims to summarize and interpret the guidelines, in order to promote clinicians’ understanding and optimize perioperative medical treatment in adult cardiac surgery.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

In 2022, many excellent clinical studies emerged in the field of cardiovascular surgery. Selecting papers published in The New England Journal of Medicine and other top medicine and cardiology journals, this review focused on the research progress on 7 topics in the field of cardiovascular surgery: coronary artery surgery, vascular surgery, valvular surgery, structural heart disease, congenital heart disease, heart transplantation, perioperative management, and special population.

Cardiac surgery presents specific challenges in conducting randomized controlled trials (RCTs). The American Heart Association made a scientific statement of methodological standards, with the purpose to review key concepts and standards in design, implementation, and analysis of cardiac surgery RCTs, and to provide recommendations. Recommendations include an evaluation of the suitability of the research question, clinical equipoise, feasibility of enrolling a representative patient cohort, impact of practice variations on the effect of the study intervention, likelihood and impact of crossover, and duration of follow-up. Trial interventions and study end points should be predefined, and adequate deliverability of the trial interventions should be ensured. Every effort must be made to keep a high completeness of follow-up. Trial design and analytic techniques must be tailored to the specific research question and trial setting. In this paper, the authors made an interpretation of this scientific statement based on their practical experience.

BackgroundDandelion is commonly used in traditional Chinese medicine with several active compounds found in extracts. It has a variety of pharmacological effects, such as a reduction in swelling and inflammation, and detoxification. The mechanism by which dandelion extract inhibits the inflammatory response in skeletal muscle cells remains unknown; therefore, the aim of this study was to investigate the effects of dandelion extract root on the proliferation of skeletal muscle cells and the alleviation of lipopolysaccharide (LPS)-induced inflammatory response in vitro.

MethodsRat skeletal muscle cells were isolated from Sprague-Dawley rat and cultured in vitro which were cultured in basal medium, or medium containing LPS or dandelion extract. Cell counting kit-8 (CCK-8) was employed to measure cell proliferation; meanwhile, the optimal concentration of dandelion extract and treatment time were selected. Crystal violet staining was used to detect the proliferation of muscle cells. Western blotting analysis was used to detect the levels of inflammatory factors, myogenic factor, and p-AKT protein expression.

ResultsThe optimal concentration and treatment time of dandelion extract for the following study were 5 mg/ml and 4 days, respectively. Dandelion extract was found to increase proliferation of rat skeletal muscle cells (t = 3.145, P < 0.05), with the highest effect observed at 5 mg/ml. LPS was found to decrease proliferation of skeletal muscle cells (t = -131.959, P < 0.001), and dandelion extract could against this affection (t = 19.466, P < 0.01). LPS could induce expression of inflammatory factors, including interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α (IL-1β: t = 9.118, P < 0.01; IL-6: t = 4.346, P < 0.05; TNF-α: t = 15.806, P < 0.05), and dandelion extract was shown to reduce LPS-induced expression of IL-1β, IL-6 and TNF-α (IL-1β: t = -2.823, P < 0.05; IL-6: t = -3.348, P < 0.01; and TNF-α: t = -3.710, P < 0.01). Furthermore, LPS was also shown to decrease expression of myogenic factor, including myod1 and myogenin (MyoD1: t = 4.039, P < 0.05 and myogenin: t = 3.300, P < 0.01), but dandelion extract was shown to against this effect of LPS (MyoD1: t = -3.160, P < 0.05 and myogenin: t = -3.207, P < 0.01). And then, LPS was found to increase expression of p-AKT protein (p-AKT/AKT: t = 4.432, P < 0.05). Moreover, expression of p-AKT protein was found to decrease, with 5 mg/ml of dandelion extract (p-AKT/AKT: t = -3.618, P < 0.05).

ConclusionsThe findings indicate that dandelion extract plays an important role in skeletal muscle cells viability regulation, promote cells proliferation by increasing level of p-AKT protein expression, and reduce LPS-induced expression of inflammatory factors, inhibiting the inflammatory response of rat skeletal muscle cells.

ObjectiveTo study the influence of povidone-iodine (PI) versus that of the benzethonium chloride wipe (BCW) on semen collection and semen quality of sperm donors undergoing penile skin disinfection and provide some evidence for the selection of disinfection methods for semen collection.

METHODSWe used PI from August to December 2015 and BCWs from January to July 2016 for penile skin disinfection before semen collection, with two samples from each donor, one collected with and the other without penis skin disinfection (the blank control group). After semen collection, we conducted a questionnaire investigation on the influence of the two disinfection methods on semen collection and compared the semen parameters between the two groups of sperm donors.

RESULTSTotally, 185 sperm donors were included in this study, of whom 63 underwent penile skin disinfection with PI and the other 122 with BCWs before semen collection. Statistically significant differences were found between the PI and BCW groups in the adaptability to the disinfectant and rigid disinfection procedures (P <0.05), but not in the other items of the questionnaire (P >0.05). Compared with the sperm donors of the blank control group, those of the PI group showed statistically significant difference in the percentage of progressively motile sperm (PMS) (［63.02 ± 3.18］% vs ［61.45 ± 4.78］%, P<0.05), but not in the abstinence time (［4.97 ± 1.79］ vs ［4.7 ± 0.94］ d, P >0.05), semen volume (［4.11 ± 1.54］ vs ［4.15 ± 1.61］ ml, P >0.05), sperm concentration (［110 ± 29.6］ vs ［107.5 ± 31.79］ ×10⁶/ml, P >0.05), or total sperm count (［439.10 ± 170.13］ vs ［434.02 ± 186.91］ ×106/ejaculate, P >0.05), while those of the BCW group exhibited no remarkable difference in any of the above parameters (P >0.05). Among the samples with abnormal semen quality, significantly fewer were found with abnormal PMS in the BCW than in the PI group (1.64% ［2/122］ vs 9.68% ［6/62］, P <0.05). However, there were no significant differences between the PI and BCW groups in the abnormal semen volume, abnormal sperm concentration, or the rate of semen bacterial contamination (P >0.05).

CONCLUSIONSBefore semen collection from donors, penile skin disinfection with povidone-iodine may affect both the semen collection process and the quality of donor sperm, while the benzethonium chloride wipe can reduce the influence on the semen collection process and does not affect the semen parameters.

Objective To investigate the effect of humidex combined with mean temperature and relative humidity on the incidence of bacillary dysentery in Hefei. Methods Daily counts of bacillary dysentery cases and weather data in Hefei were collected from January 1, 2006 to December 31, 2013. Then, the humidex was calculated from temperature and relative humidity. A Poisson generalized linear regression combined with distributed lag non-linear model was applied to analyze the relationship between humidex and the incidence of bacillary dysentery, after adjusting for long-term and seasonal trends, day of week and other weather confounders. Stratified analyses by gender, age and address were also conducted. Results The risk of bacillary dysentery increased with the rise of humidex. The adverse effect of high humidex (90 percentile of humidex) appeared in 2- days lag and it was the largest at 4-days lag (RR=1.063, 95%CI:1.037-1.090). Subgroup analyses indicated that all groups were affected by high humidex at lag 2-5 days. Conclusion High humidex could significantly increase the risk of bacillary dysentery, and the lagged effects were observed.
