Introduction: Insufficient withdrawal duration of antithrombotics leads to excessive bleeding after major surgery. We hypothesize that intraoperative hemoadsorption (HA) can reduce postoperative allogeneic transfusion requirements and excessive bleeding events (EBE), without an increase in ischemic/thromboembolic events (ITE) in patients who have taken antithrombotics and undergone nonelective cardiac surgery.

Methods: A total of 460 patients admitted to our hospital from 2018 to 2022 were included in this study and divided into two groups: HA and non-HA.

Objectives: To study the clinical characteristics of plastic bronchitis (PB) in children and investigate the the risk factors for recurrence of PB.

Methods: This was a retrospective analysis of medical data of children with PB who were hospitalized in Children's Hospital of Chongqing Medical University from January 2012 to July 2022. The children were divided into a single occurrence of PB group and a recurrent PB group and the risk factors for recurrence of PB were analyzed.

The antibiotic desertomycin A and its previously undescribed inactive -succinylated analogue, desertomycin X, were isolated from sp. strain YIM 121038. Genome sequencing and analysis readily identified the desertomycin biosynthetic gene cluster (BGC), which lacked genes encoding acyltransferases that would account for desertomycin X formation.

Resveratrol (RV) is a well-known polyphenolic compound in various plants, including grape, peanut, and berry fruits, which is quite famous for its association with several health benefits such as anti-obesity, cardioprotective neuroprotective, antitumor, antidiabetic, antioxidants, anti-age effects, and glucose metabolism. Significantly, promising therapeutic properties have been reported in various cancer, neurodegeneration, and atherosclerosis and are regulated by several synergistic pathways that control oxidative stress, cell death, and inflammation. Similarly, RV possesses a strong anti-adipogenic effect by inhibiting fat accumulation processes and activating oxidative and lipolytic pathways, exhibiting their cardioprotective effects by inhibiting platelet aggregation.

Article Synopsis
  • The study aims to evaluate the effectiveness of different empirical antibiotic treatments in children with Staphylococcus aureus sepsis and how these treatments impact patient outcomes.
  • A total of 78 children were analyzed across four antibiotic treatment groups: carbapenems, β-lactams, vancomycin, and vancomycin combined with β-lactams, looking at various clinical factors.
  • Results showed that although general health status was similar across groups, those on carbapenems faced higher rates of septic shock and in-hospital mortality, with APACHE II scores of 15 or higher being a significant risk factor for severe outcomes.

Huge numbers of bacteria reside in the digestive tract of host and these microorganisms play a vital role in the host health, especially in the digestion of food and the development of immune system. Host phylogeny and diet, especially long-term diet, both have great influence on the gut bacterial community. Other aspects of host, such as gender, age, and the geography and weather they lived, are also correlated to their gut bacterial community.

A novel actinobacterium, designated YIM 101593T, was isolated from the faeces of a primate (Rhinopithecus roxellanae) living in Yunnan Wild Animal Park in Yunnan province, south-west China. The isolate was Gram-stain-positive, facultatively anaerobic, coccus-shaped, oxidase-negative and motile. The cell wall contained meso-diaminopimelic acid as its diagnostic diamino acid, and mannose, ribose, glucose, galactose and arabinose were detected as the main whole-cell sugars.
