[Diagnosis and treatment status of perioperative anemia in patients with gastrointestinal neoplasms: a multi-center study in Hubei Province].

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

[Clinical research of a continuous auscultation recorder based on artificial intelligence].

Objective: To investigate the feasibility and clinical significance of a continuous auscultation recorder of bowel sounds based on artificial intelligence in monitoring the bowel sounds. Methods: From November 1,2018 to August 12,2019, a continuous auscultation recorder of bowel sounds was applied to monitor the perioperative bowel sounds of 31 patients undergoing colorectal surgery, in order to discovery underlying rules which might be used to guide clinical practice. Results: After the operation, the bowel sounds continued to exist for (1.8±0.8) h, and then gradually weakened or disappeared, and recovered gradually after (11.2±3.5) h. The first exhaust and the first defecation were detected at the time of (22.7±5.8) h and (28.7±6.9) h after surgery, respectively. The bowel sounds rate increased after eating, and decreased significantly after exhaust/defecation. Conclusions: The continuous auscultation recorder of bowel sounds based on artificial intelligence was safe and effective, which can afford help to clinical evaluation.

The Gap Study (GapS) interview--developing a process to determine the meaning and determinants of quality of life in children with arthritis and rheumatic disease.

OBJECTIVE: Quality of Life (QOL) is a ubiquitous yet rarely precisely defined term. QOL may be determined by the differences (gaps) between our current situation and our expectations. Contemporary methods of measuring QOL often do not take these gaps into consideration. We performed this study to develop items and methods for measuring and valuing these gaps in order to better determine individual QOL for children with rheumatic diseases. METHODS: We generated items from literature review, other QOL measures and interviews with pediatric rheumatology patients and their families. Gap-scales to measure the discrepancy between a child's current state and the expected or desired state were designed and tested iteratively in pilot interviews. RESULTS: Thirty-one children (mean age=13.5 years, age range=6-17 years) and 22 parents were recruited through pediatric rheumatology clinics. The process of item generation, reduction and preliminary formatting yielded a list of 72 items. We developed a 3-point categorical scale of importance and a vertical visual analog scale (VAS) to determine individual valuation of items. 5 gap-scales were developed to reflect different aspects of the discrepancy between the child's current and expected or desired states for different QOL items. CONCLUSIONS: We have developed a QOL interview based on theory that we can now test to see if it will enrich our understanding of the determinants of QOL in pediatric rheumatology patients and other chronically ill children.
