RESUMO
Objective: To explore the incidence and the risk factors of post-polypectomy bleeding and polyp recurrence after colonoscopic high-frequency electrocoagulation snare polypectomy. Methods: Clinical data of 1 826 children who underwent colonoscopic high-frequency electrocoagulation snare polypectomy in the Children's Hospital, Zhejiang University School of Medicine from January 2009 to December 2020 was retrospectively analyzed. Demographic characteristics, endoscopic manifestations, pathological features, diagnosis, occurrence of post-polypectomy bleeding and polyp recurrence were collected. The associated risk factors were analyzed by Logistic regression. Results: A total of 1 826 children (1 191 males and 635 females) with 1 967 polypectomies were included. The age was 4.6 (3.2, 6.4) years at initial diagnosis. According to the initial colonoscopy, 1 611 children (88.2%) had solitary polyps, 1 707 children (93.5%) had pedicled polyps, 1 151 children (63.0%) had polyps involving the rectum, and 1 757 children (96.2%) had hamartomatous polyps. Polyposis syndromes were diagnosed in 73 children (4.0%). The post-polypectomy bleeding occurrence was 3.8% (75/1 967). Polyps recurred in 88 children (4.8%). Girls (OR=2.01, 95%CI 1.26-3.23) and sessile polyps (OR=2.28, 95%CI 1.15-4.49) were risk factors for post-polypectomy bleeding (both P<0.05). Multiple polyps (OR=17.49, 95%CI 9.82-31.18), right-colon involvement (OR=3.44, 95%CI 1.89-6.26) and non-hamartoma (OR=2.51, 95%CI 1.04-6.07) were risk factors for polyp recurrence (all P<0.05). Conclusions: Colonoscopic high-frequency electrocoagulation snare polypectomy has low incidence of post-polypectomy bleeding and polyp recurrence. Female patients and sessile polyps have higher risk for post-polypectomy bleeding. Multiple polyps, right-colon involvement and non-hamartoma polyps increase the risk for polyp recurrence.

Objective: To analyze the clinical characteristics of X-linked inhibitor of apoptosis (XIAP) deficient patients with clinical manifestation of Crohn's disease. Methods: Clinical manifestations, laboratory investigations, genetic testing and therapeutic interventions of one case of XIAP deficiency who was admitted to Department of Gastroenterology in Children's Hospital, Zhejiang University School of Medicine in May 2016 were summarized. PubMed and Chinese database for articles published from January 2016 to June 2017 were searched using the key words of'Crohn's disease'and'XIAP', and the relevant literature was reviewed. Results: The case we reported was a 6-year-1-month-old boy with recurrent bloody stool for 2 months, and abdominal pain with fever for 2 weeks. The patient had a past history of hemophagocytic lymphohistiocytosis (HLH) and epilepsy in the past one year. Complete blood cell count showed mild anemia (Hb108 g/L). The patient had an elevated high-sensitivity C reactive protein (86 mg/L) and erythrocyte sedimentation rate (46 mm/1h) . White blood cells, pus cells and red blood cells were found on routine stool examination. Biochemical panel showed hypoalbuminemia (25.2 g/L) , elevated transaminase (alanine aminotransferase 175 U/L, aspartate transaminase 229 U/L) , hypertriglyceridemia (4.41 mmol/L) , and hyperferritinemia (>1 650.0 µg/L) . Magnetic resonance enterography revealed the intestinal wall thickening and increased enhancement in parts of illeum and colon. Capsule endoscopy revealed multiple ulcers in jejunum. Colonoscopy showed multiple ulcers in colon and the pathological examination revealed chronic inflammation in mucosa of terminal ileum and colon, which was combined with partial necrosis and ulceration. Some phagocytes were seen in bone marrow smears. The patient was given multiple diagnoses, including hemophagocytic lymphohistiocytosis, Crohn's disease, sepsis, epilepsy, severe malnutrition, and hypoproteinemia. The pediatric Crohn's disease activity index (PCDAI) was 37.5. Genetic testing identified a hemizygotic mutation of c.910G>T chrX:123022501 p.G304X in XIAP. The parents had no such mutation. The patient showed response to infliximab with oral intake of mercaptopurine and corticosteroids, and had remission with PCDAI of 0. There were 9 relevant articles (Chinese 0 English 9), which showed 33.3% XIAP deficient patients manifested with inflammatory bowel disease(IBD), who might have other manifestations such as hemophagocytic lymphohistiocytosis or splenomegaly simultaneously or sequentially. Those patients showed poor response to monotherapy. Conclusion: XIAP deficient patients have various clinical manifestations. Genetic testing is important to those male pediatric IBD patients who have the complicated symptoms or little response to standard therapy.

Objective: To investigate the effect of occupational exposure on job burnout in nurses, and to analyze the mediating effect of negative emotion between occupational exposure and job burnout and the regulatory effect of supervisor support on occupational exposure and negative emotion. Methods: From September to December, 2015, simple random sampling was used to select 543 nurses from six tertiary hospitals in Zhejiang Province, China. The questionnaires consisted of occupational exposure risk questionnaire, negative emotion questionnaire, supervisor support questionnaire, and job burnout questionnaire. Results: The total score of occupational exposure risk in nurses was 11.43±7.19; the score of emotional exhaustion was 3.19±1.24, the score of low sense of personal accomplishment was 3.02±1.21, and the score of sense of working indifference was 2.24±1.06. There were significant differences in occupational exposure score between nurses with different sexes (t=2.61, P<0.01) and working years (F=4.49, P<0.01) . There were significant differences in the scores of emotional exhaustion and low sense of personal accomplishment in nurses with different sexes (t=5.25, P<0.001) and working years (t=-3.48, P<0.01) . Occupational exposure had positive effects on negative emotion (ß=0.41, P<0.05) , emotional exhaustion (ß=0.47, P<0.05) , sense of working indifference (ß=0.42, P<0.05) , and low sense of personal accomplishment (ß=0.17, P<0.05) . Negative emotion had a partial mediating effect between occupational exposure and emotional exhaustion (total effect size 30.5%, P<0.05) and between occupational exposure and sense of working indifference (total effect size 37.1%, P<0.05) . Negative emotion had a complete mediating effect between occupational exposure and low sense of personal accomplishment (ß=0.08, P>0.05) . Supervisor support negatively regulate the effects of occupational exposure and negative emotion (F=21.73, P<0.001) . Conclusion: In nurses, occupational exposure has a direct positive effect on job burnout and indirectly influences job burnout via negative emotion. Supervisor support can reduce the negative impact of occupational exposure on negative emotion.
