We identified risk factors associated with intraoperative or with postoperative hypoxemia in rigid bronchoscopy which included patient age, type of FB, duration of surgical procedure, pneumonia before the procedure, ventilation mode, and duration of emergence from anesthesia. These results provide evidence that will help clinicians to reduce the incidence of hypoxemia in high-risk children.

To investigate the incidence and outcome of major complication following conventional transarterial embolization/chemoembolization (TAE/TACE) therapy for hepatocellular carcinoma (HCC).From May 2010 to May 2016, all patients with major complication following conventional TAE/TACE for HCC were included. Major complication was defined as admission to a hospital for therapy, an unplanned increase in the level of care, prolonged hospitalization, permanent adverse sequelae, or death after conventional TAE/TACE therapy by Society of Interventional Radiology.During the study period, a total of 2863 TAE/TACE procedures were performed among 1120 patients, and a total of 24 patients (21 male and 3 female) developed major complication with the incidence of 2.1% (24/1120) per patient and 0.84% (24/2863) per TAE/TACE procedure. The major complications were liver rupture (n = 6), liver abscess (n = 5), femoral artery pseudoaneurysm (n = 3), cholecystitis (n = 2), biloma (n = 2), pulmonary embolism (n = 2), and 1 each of the following: cerebral lipiodol embolism, tumor lysis syndrome, partial intestinal obstruction, gallbladder perforation. The mean interval from last TAE/TACE procedure to the diagnosis of major complication was 11.1 ± 7.7 days. The treatments of the complications were conservative treatment (n = 12), conservative treatment plus percutaneous drainage (n = 3), ultrasound-guided thrombin injection (n = 3), conservative treatment plus TAE (n = 2), and conservative treatment plus surgery (n = 2). Of the 24 patients, 20 patients were recovered, and remaining 4 patients were died of major complications; therefore, the mortality rate of major complication was 16.7% (4/24).Major complication following conventional TAE/TACE therapy is uncommon; the outcomes are benign of most major complications, but some are mortality.

Ischaemic reperfusion (IR) injury is characterized as the damage caused to the tissues due to the return of blood supply (reperfusion) after a brief duration of lack of oxygen (ischaemia). Affecting a wide range of population and organs, they are usually observed as a consequence to conditions such as trauma, shock, strangulation, mesenteric artery thrombosis and intestinal obstruction. 1-4 Ischaemia by itself damages the cells, which is further exacerbated by the restoration of blood flow resulting in increased cell death and release of inflammatory response elements that ultimately leads to multiple organ failure. 5 Of the organs affected by IR injury, the intestine has been described as the most vulnerable to this damage and severe intestinal injury could lead to the need for immediate surgical

Many species exhibit transgenerational plasticity by which environmental cues experienced by either parent can be transmitted to their offspring, resulting in phenotypic variants in offspring to match ancestral environments. However, the manner by which paternal experiences affect offspring plasticity through epigenetic inheritance in animals generally remains unclear. In this study, we examined the transgenerational effects of population density on phase-related traits in the migratory locust Locusta migratoria. Using an experimental design that explicitly controls genetic background, we found that the effects of crowd or isolation rearing on phase plasticity could be inherited to the offspring. The isolation of gregarious locusts resulted in reduced weight in offspring eggs and altered morphometric traits in hatchlings, whereas crowding of solitarious locusts exhibited opposite effects. The consequences of density changes were transmitted by both maternal and paternal inheritance, although the expression of paternal effects was not as pronounced as that of maternal effects. Prominent expression of heat-shock proteins (Hsps), such as Hsp90, Hsp70 and Hsp20.6, could be triggered by density changes. Hsps were significantly upregulated upon crowding but downregulated upon isolation. The variation in parental Hsp expression was also transmitted to the offspring, in which the pattern of inheritance was consistent with that of phase characteristics. These results revealed a paternal effect on phase polyphenism and Hsp expression induced by population density, and defined a model system that could be used to study the paternal epigenetic inheritance of environmental changes.
