Background/Aims:
Constipation can be a chronic condition that impacts daily functioning and quality of life (QoL). To aid healthcare providers in accurately assessing patient symptoms and treatment outcomes, patient-related outcome measures (PROMs) have been increasingly adopted in clinical settings. This review aims to (1) evaluate the methodological quality and measurement properties of constipationrelated PROMs, using the COnsensus-based Standards for the selection of health Measurement INtruments (COSMIN) criteria; and (2) assess the modes of digital dissemination of constipation-related PROMs.
Methods:
PubMed, Embase, and PsycINFO databases were searched and 11 011 records ranging from 1989 to 2020 were screened by 2 independent reviewers. A total of 26 studies (23 PROMs; 18 measuring symptom-related items and 5 measuring constipation-related QoL items) were identified for the review and assessed.
Results:
There were multiple variations between PROMs, including subtypes of constipation, methods of administration, length of PROM and recall period. While no PROM met all the COSMIN quality standards for development and measurement properties, 5 constipationrelated PROMs received at least 4 (out of 7) sufficient ratings. Only 2 PROMs were developed in Asia. Five PROMs were administered through digital methods during the validation process but methods of adapting the PROMs into digital formats were not reported.
Conclusions
The constipation-related PROMs identified in this review present varying quality of development and validation, with an overall need for improvement. Further considerations should be given towards more consistent methodology and reporting of PROM development, increase in culturally-specific PROMs, and better reporting of protocol for the digitization of PROMs.

Objective: To analyze the effect of the identification and evaluation of Escherichia (E.) coli and Shigella, based on the upstream flanking sequences of CRISPR1. Methods: Both CRISPR and cas sequences were obtained through the BLAST with repeating sequences against the publicly complete genome in GenBank that related to E. coli and Shigella. Clustal X was used to perform multi-sequences alignment of the flanking sequences. PCR method was used to amplify the upstream flanking sequences of CRISPR1 in order to appraise the effect of identification and evaluation of upstream flanking sequences on E. coli and Shigella, which were based on the upstream flanking sequences of CRISPR1. Results: The results showed that 73.4% of the strains containing the I-E CRISPR/Cas that belonged to the phylogroups A, B1, D while 8.4% strains carried the I-F CRISPR/Cas. Another 17.2% of the strains owned CRISPR3-4 (non-CRISPR/Cas) only belonged to the phylogroups B2. All the Shigella strains carried I-E CRISPR/Cas. More than 99% of similarity the CRISPR1 upstream-flanking sequences was seen in E. coli (except B2) and Shigella and E. coli (B2). Both sensitivity and specificity were greater than 91% after PCR amplification in the region to identify the E.coli and Shigella. Conclusion: The upstream of CRISPR1 could achieve a preliminary identification effect on E.coli and Shigella.

Objective: To obtain experience and generate suggestions for reducing average hospital stays, optimizing perioperative management of patients with gastric cancer and improving utilization of medical resources by analyzing the factors influencing super-long hospital stays in patients undergoing radical gastrectomy in the age of enhanced recovery after surgery (ERAS). Methods: This was a case-control study. Inclusion criteria: (1) pathologically diagnosed gastric adenocarcinoma; (2) radical surgery for gastric cancer; and (3) complete clinicopathologic data. Exclusion criteria: (1) history of upper abdominal surgery; (2) presence of distant metastasis of gastric cancer or other ongoing neoplastic diseases; (3) concurrent chemoradiotherapy; and (4) preoperative gastric cancer-related complications such as obstruction or perforation. The study cohort comprised 285 eligible patients with hospital stays of ≥30 days (super-long hospital stay group). Using propensity score matching in a 1:1 ratio, age, sex, medical insurance, pTNM stage, and extent of surgical resection as matching factors, 285 patients with hospital stays of < 30 days during the same period were selected as the control group (non-long hospital stay group). The primary endpoint was relationship between pre-, intra-, and post-operative characteristics and super-long hospital stays. Clavien-Dindo grade was used to classify complications. Results: Univariate analysis showed that number of comorbidities, number of preoperative consultations, preoperative consultation, inter-departmental transference, operation time, open surgery, blood loss, intensive care unit time, presence of surgical or non-surgical complications, Clavien-Dindo grade of postoperative complications, and reoperation were associated with super-long hospital stays (all P<0.05). Inter-departmental transference (OR=4.876, 95% CI: 1.500-16.731, P<0.001), preoperative consultation time ≥ 3 d (OR=1.758, 95%CI: 1.036-2.733, P=0.034), postoperative surgery-related complications (OR = 6.618, 95%CI: 2.141-20.459, P=0.01), and higher grade of complications (Clavien-Dindo Grade I: OR = 7.176, 95%CI: 1.785-28.884, P<0.001; Clavien-Dindo Grade II: OR = 18.984, 95%CI: 6.286-57.312, P<0.001; Clavien-Dindo Grade III-IV: OR=7.546, 95%CI:1.495-37.952, P=0.014) were independent risk factors for super-long hospital stays. Conclusion: Optimizing preoperative management, enhancing perioperative management, and surgical quality control can reduce the risk of prolonging average hospital stay.
