assist clinicians in predicting the prognosis of HCC patients with LN metastasis and may provide a rationale for treatment options.
Although the peripherally inserted central catheter (PICC) has been widely utilized, there is still a lack of large sample size-based relevant risk factor investigation for the children with blood diseases in a single center of China.

We performed a retrospective cohort study through including a total of 2,974 cases aged 0-18 years with blood diseases and PICC insertion. Success rates of different PICC operation techniques were compared. Targeting the common PICC-related complications, we performed the univariate and multivariate logistic regression analyses. Then, based on the screened risk factors, the prediction modeling analysis of binary logistic regression was conducted.

The "B-ultrasound plus Seldinger technology" showed a higher success rate of PICC placement than the "non-assistive blind insertion". The catheter type was closely linked to the occurrence of catheter occlusion. The age, insertion site, and catheter type might be the risk factors of phlebitis, while the insertion site, operation season, and catheter type might be associated with catheter fracture. Furthermore, based on these risk factors, we established the nomogram prediction models of phlebitis, rash occurrence, and catheter fracture, respectively, which shows a good predictive ability and a moderate level of predictive accuracy.

Our findings first shed new light on the preoperative estimation of the risk factors of PICCrelated complications for the children with blood diseases in China.

The prognosis of descending necrotizing mediastinitis (DNM), especially that extending inferiorly to the carina, remains poor. The identification of additional prognostic factors may improve the prognosis.

We retrospectively analyzed six patients who underwent thoracic surgery for DNM extending to the anterior and posterior mediastinum inferior to the carina (Endo classification type IIB) from 2014 to 2020. We reviewed their characteristics, clinical course, causative bacteria, and treatment to investigate their prognostic factors.

The median patient age was 62 years. Five patients were men and one patient was a woman. The causative disease in three of the patients was pharyngolaryngeal, and for the others, it was an odontogenic infection. Five patients had sepsis and four had disseminated intravascular coagulation (DIC) at surgery. Four patients had polymicrobial infections of aerobic and anaerobic bacteria, all of whom showed gas bubbles on a chest computed tomography scan and detection of Streptococciotic therapy and aggressive drainage and surgery.
Providing high-quality training to residency students during the coronavirus 2019 (COVID-19) pandemic has been a goal of our institution. Since 2108, we began to take microlectures to students teaching. Microlectures are online presentations, and the microlecture teaching method has many advantages, such as a short teaching time, situational resource composition, diverse communication, strong pertinence and can attend microlectures from home. The aim of the present study was to evaluate the advantages of the microlecture teaching method on students in standardized residency training.

Students from our department were randomly divided into the traditional teaching group (control group) and the microlecture teaching group (observation group). selleck The teaching duration for both groups was 3 months. All students were assessed on basic knowledge of the neurology before enrollment. After the teaching session, the students were assessed on teaching effect, theoretical operation, and clinical practice satisfaction. The students also evaluated the teachers, and the teachers evaluated the students.

A total of 84 students participated in the study and were divided equally into the observation group (42 students) and the control group (42 students). The results showed that the rate of reaching the standard of teaching effect, achievement of theory and operation, satisfaction with clinical practice, the student's grades by teachers, and student satisfaction with teachers were significantly higher in the observation group than in the control group (all P<0.05).

The microlecture teaching method can effectively improve the clinical teaching effect for neurology students and should be adopted in clinical teaching, especially during the COVID-19 pandemic.

Ischial pressure sores often recur, the surgical choice often troubled the surgeon, because surgery repair should consider future reconstructive procedures. The purpose of this article is to present a new surgical option for the reconstruction of primary or recurrent ischial pressure sores by using an inferior gluteal artery of the descending branch perforator flap.

A study involving patients suffering from ischial pressure sores was performed from March 2016 to August 2020. Patients with large defects, for which direct closure was not possible, underwent reconstructive surgery using an inferior gluteal artery descending branch perforator flap. Collected data included age, diabetes, wound culture, size of the wound, whether or not negative pressure therapy was received, operative time, intraoperative blood loss, and postoperative complications. Patients were followed up through outpatient visits or by telephone.

Five patients with ischial pressure sores (four primary and one recurrent) underwent reconstructive surgery with inferior gluteal artery descending branch perforator flap. One patient received colostomy and wound negative pressure therapy before lesion reconstruction. All patients successfully recovered without postoperative complications. The follow-up period ranged from 4 to 31 months. No wound disruption or recurrence was recorded.

Inferior gluteal artery descending branch perforator flap treatment of ischial pressure sores is a simple and feasible method for preserving the inferior gluteal artery's main vascular perforators and could be used as a future surgical option.
