Objective:To retrieve, appraise and synthesize evidence regarding the prevention and management of high-output ileostomy in post-enterostomy patients, thereby providing a scientific reference for clinical practice.Methods:A computerized search was conducted, systematically exploring national and international databases, as well as the websites of pertinent associations, to gather evidence relevant to the topic. The literature types included clinical decision-making, evidence summaries, guidelines, expert consensus, and systematic reviews. The search timeframe was established from the date of database construction until 23 August 2024. The methodological quality assessment of the literature, along with the extraction and synthesis of the evidence, was performed by two independent researchers utilizing established criteria and adhering to rigorous standards.Results:A total of 13 papers were included in the review, comprising one clinical decision, four guidelines, and eight systematic reviews. Eighteen pieces of best evidence were distilled and summarized across six key areas: diagnosis and risk identification, fluid/diet/nutrition management, medication administration, skin management, monitoring and health education, and follow-up care.Conclusions:The clinical practice rationale for the prevention and management of high-output ileostomy in post-enterostomy patients, when summarized, would offer scientific and effective evidence-based support for practice changes by clinical care staff. The practical application and translation of this evidence should thoroughly consider the nuances of clinical practice in China, as well as individual patient differences, to ensure the effective implementation of the best evidence for maximizing patient benefit.

Objective:To quantitatively evaluate the changes of the sciatic nerve of rabbits following acute cold exposure and intraperitoneal lavage rewarming therapy by applying shear wave elastography（SWE）technology.Methods:Thirty healthy adult New Zealand white rabbits，weighing approximately（4.0 ± 0.2）kgResults:Body temperature comparison：the body temperature of all 3 groups decreased at T2 compared to T1，with statistically significant differences（all P<0.05）. By T4，the body temperature of all groups had returned to normal，showing no significant differences compared to T1（ P>0.05）. The peritoneal lavage + rewarming platform group showed a faster recovery rate in body temperature during T2-T3 compared to both the rewarming platform group and the blank control group，with statistically significant differences（all P<0.05）. There were no significant differences in the recovery rate between the rewarming platform group and the blank control group during T2-T3（all P>0.05）. Comparison of conventional ultrasound parameters：the longitudinal width，cross-sectional area，and perimeter of the sciatic nerve showed statistically significant differences between T2 and T1（all P<0.05）. No significant differences were observed between T3 and T4，or between T1 and T4（all P>0.05）. Comparison of SWE parameters：T2 phase showed an increase in SWE values of the sciatic nerve，with statistically significant differences in the maximum（Emax）and average（Emean）Young's modulus compared to T1 and T4（all P<0.05）. No significant differences were observed between T1 and T4（all P>0.05）. Transmission electron microscopy results：under acute cold exposure，the sciatic nerve showed swelling，with vacuole formation visible in the axons. After peritoneal lavage rewarming therapy，the morphology of the sciatic nerve returned to normal. Conclusions:Following acute cold exposure，the rabbit's sciatic nerve exhibits contraction，with increased stiffness，which can be quantitatively assessed using conventional ultrasound combined with SWE. Peritoneal lavage therapy is an effective rewarming method that significantly enhances the rewarming rate.

Objective:To explore the epidemiological characteristics of human metapneumovirus (hMPV) in children hospitalized for acute respiratory tract infections in Hebei, and provide a theoretical basis for the clinical diagnosis and treatment of acute respiratory tract infections in children in Hebei.Methods:Retrospectively, 41 499 children hospitalized in Hebei Children′s Hospital for acute respiratory tract infections from January 2017 to December 2021 were included to analyze the morbidity of children of different genders and ages, and in different seasons, and to statistically analyze the epidemiological data such as the positive detection rate of hMPV, the detection rates of mixed infections with other pathogens, and the clinical diagnosis.Results:The overall positive detection rate of hMPV in hospitalized children with acute respiratory infections from 2017 to 2021 was 5.94%(2 464/41 499), with the highest positive detection rate of hMPV in the age group of 3 to 4 years (7.66%, 520/6 789) and the lowest in the age group of ≥5 years (2.89%, 180/6 225), with a statistically significant difference ( P<0.001); the positive detection rates in male and female children were respectively 5.97%(1 496/25 056) and 5.94%(968/16 443), and the difference was not statistically significant ( P>0.05). The positive detection rates of hMPV from 2017 to 2021 were 5.10%(408/7 998), 9.64%(915/9 491), 4.27%(426/9 969), 5.91%(368/6 226), and 4.44%(347/7 815), respectively, and the positive detection rate of hMPV in 2018 was significantly higher than that in the other years ( P<0.001). hMPV circulated throughout the year, with obvious seasonality, with the highest positive detection rate in spring and winter.The mixed detection rate of hMPV with other respiratory pathogens was 42.74% (1 053/2 464), of which mixed detection with rhinovirus was the most common, with a mixed detection rate of 48.24%(508/1 053).Clinical diagnosis of hPMV-positive children was mostly bronchopneumonia. Conclusions:hMPV is one of the important pathogens in hospitalized children with acute respiratory infections in Hebei, which is common in children under 5 years of age and can occur throughout the year, with peak epidemics in winter and spring. Mixed infections of hMPV with other respiratory pathogens are common and can increase the risk of worsening clinical symptoms in children.

Objective:To analyze the association between physical activity levels and all-cause mortality risk in patients with diabetic kidney disease (DKD) and to investigate the mediating effect of inflammation.Methods:Based on National Health and Nutrition Examination Survey of America data matched with the National Death Index of America, a prospective cohort was formed, including 59 482 participants from six cycles between 2007 and 2018. After applying inclusion and exclusion criteria, 2 214 DKD patients were selected for the study. Cox proportional hazard regression models were used to analyze the impact of physical activity levels on all-cause mortality risk. The mediating effect of inflammatory markers in the association between physical activity and all-cause mortality risk was explored.Results:There were statistically significant differences in survival curves among different physical activity level groups ( P<0.001). As physical activity levels increased, the risk of mortality decreased. Patients in the high physical activity group had a lower mortality risk compared to those in the inactive group ( HR=0.64, 95% CI: 0.53-0.78), with a statistically significant difference ( P<0.001). Patients with higher physical activity levels had lower levels of inflammation (white blood cell, neutrophil, and C-reactive protein) ( P<0.001). White blood cell, neutrophil, C-reactive protein, the neutrophil-to-lymphocyte ratio (NLR), and the systemic inflammation index (SII) were independent risk factors for mortality in DKD patients ( HR>1.00), with higher risk effects observed for the combined indicator lgNLR ( HR=2.06, 95% CI: 1.76-2.41) and lgSII ( HR=1.44, 95% CI: 1.26-1.64). Mediation analysis showed that physical activity had an indirect effect on all-cause mortality risk through neutrophil, with an effect size of -0.033 (95% CI: -0.052 - -0.002), which was statistically significant ( P<0.05), with a mediation effect proportion of 9.75%. Conclusion:Physical activity is a protective factor against all-cause mortality risk in DKD patients, partly through reducing neutrophil levels.

Objective:To explore the relationships between physical activity and cognitive impairment in older adults aged ≥65 years in longevity areas in China.Methods:A total of 6 081 older adults aged ≥65 years from the Healthy Ageing and Biomarkers Cohort Study in China in 2021 were included in this study. Information about their demographic characteristics, lifestyles, and chronic disease histories were collected, the intensity of physical activity was evaluated by using Physical Activity Scale for the Elderly, and the cognitive function was evaluated by using Mini-Mental State Examination Scale (Chinese version). Multifactorial logistic regression model was used to analyze the associations between different levels and types of physical activity and cognitive impairment in older adults.Results:In the 6 081 older adults, 1 829 (30.1%) had cognitive impairment. After adjusting for confounders, older adults with T2 and T3 levels of physical activity had lower risks for cognitive impairment compared with those with T1 levels of physical activity, with ORs of 0.47 (95% CI: 0.40-0.55) and 0.22 (95% CI: 0.18-0.28). The results of different types of physical activities showed that the ORs in leisure activity T2 and T3 groups were 0.52 (95% CI: 0.44-0.63) and 0.49 (95% CI: 0.41-0.58), and the ORs in housework activity T2 and T3 groups were 0.36 (95% CI: 0.30-0.42) and 0.19 (95% CI: 0.16-0.24). There was no significant association between work-related activity and cognitive impairment. Conclusion:There is a negative association between the intensity level of physical activity and cognitive impairment, and active leisure and household activities might reduce the risk for cognitive impairment.

Objective:To analyze the molecular characteristics of prevalent Bordetella pertussis (Bp) isolates in Liaocheng City, Shandong Province in 2024. Methods:From March to August 2024, oropharyngeal swabs were collected from suspected pertussis cases at Liaocheng People′s Hospital in Shandong Province for Bp isolation. A total of 99 Bp isolates were obtained. Whole-genome sequencing was performed on all isolates, followed by Multilocus Sequence Typing (MLST), vaccine antigen-related gene typing (including ptxP, ptxA, ptxB, ptxC, ptxD, ptxE, fhaB, fim2, fim3, and prn), 23S rRNA gene typing, and phylogenetic analysis. To capture the differences between Bp isolates and vaccine strains in Liaocheng City, the international vaccine strain Tohama I and the Chinese vaccine strain CS were included in the analysis. Antimicrobial resistance testing against 11 agents was performed on 52 isolates. Results:The throat swabs of 99 Bp isolates were collected from patients aged 44 days to 42 years, and the median age of the patients was 7 (5, 8) years. All isolates ptxP were ptxP3 type. 74 isolates (74.75%) carried the prn150, while 21 isolates (21.21%) were prn-deficient. The predominant antigenic profile was ptxP3/ ptxA1/ ptxB1/ ptxC4/ ptxD1/ ptxE4/ fhaB1/ fim2-1/ fim3-1/ prn150, found in 72 isolates (72.73%). All 99 isolates carried the A2047G mutation in the 23S rRNA gene. Antimicrobial susceptibility testing showed that the MICs of macrolides and clindamycin for all 52 Bp isolates were all >256 mg/L. However, the isolates showed low MIC for seven other antimicrobials tested, including trimethoprim-sulfamethoxazole, amoxicillin, and levofloxacin. MLST typing revealed that 94 isolates (94.95%) were identified as ST-2, while 5 isolates (5.05%) belonged to a novel sequence type (ST-118). Phylogenetic analysis demonstrated that all 99 Bp isolates were highly homologous but clustered in evolutionary branches distinct from vaccine strains. Conclusion:In 2024, Bordetella pertussis isolates in Liaocheng City exhibit distinct clonal epidemic characteristics, with the predominant antigenic genotype being ptxP3/ ptxA1/ ptxB1/ ptxC4/ ptxD1/ ptxE4/ fhaB1/ fim2-1/ fim3-1/ prn150. All isolates are resistant to macrolide antibiotics.

Immune dysregulation is a critical factor in the pathogenesis of inflammatory bowel disease (IBD), and numerous studies have focused on the impact of immune cell metabolic pathways. Immune system cells dynamically adapt to the microenvironment, regulating the body's response to external stimuli through intricate metabolic pathways. This review summarizes the mechanisms by which glycolysis, fatty acid and amino acid metabolisms influence immune metabolism and thereby modulate IBD progression, offering new perspectives for the diagnosis and treatment of IBD.

Objective To develop an ICU patient care difficulty index based on psychosocial factors and to evaluate its reliability and validity,thereby providing a comprehensive tool for assessing the difficulties in ICU patient care.Methods Guided by Guarinoni theory,an index system was developed through systematic literature reviews,semi-structured interviews,two rounds of Delphi expert consultation and the analytic hierarchy process.Based on the drafted system,a questionnaire was formulated.The tests for validity and reliability were conducted on 290 patients selected by convenience sampling.Results The finalised ICU patient care difficulty index system was composed of 5 primary indices(the general condition of the patient,disease condition,nursing condition,social support,and organizational characteristics),13 secondary indices and 27 tertiary indices.The Kendall's coefficient of coordination W values were 0.380 and 0.498,respectively,indicating a statistically significant agreement(both P<0.001).The system demonstrated a robust reliability(Cronbach's α=0.896)and a good internal consistency.Validity was confirmed through a scale level-content validity index(S-CVI)of 0.94 and the item level-content validity indices(I-CVI)ranged from 0.87 to 1.00.Structural validity analysis,based on 8 extracted public factors,showed a cumulative variance contribution rate of 66.34%.Conclusion The ICU patient care difficulty index system shows a high reliability and validity,making it a valuable tool for accurately quantification of the difficulty in ICU patient care.This system provides a scientific basis for allocation of ICU nursing resource and performance distribution.

Objective To apply the image recognition method based on distance graph convolutional network to the image processing of malaria-infected erythrocytes for realizing the multi-stage recognition of malaria and improving the diagnostic efficiency of malaria.Methods A multi-stage malaria recognition model based on distance graph convolutional network was proposed.A radial basis function was firstly added in KNN graph construction algorithm to construct adjacency matrix and assign weights to the nearest-neighbor nodes according to the similarity between nodes,so as to weaken the effects of the distant nearest-neighbor nodes on the central node.Then,attention mechanism was introduced to update adjacency matrix dynamically in the graph convolutional network for making the model pay attention to near-neighbor nodes with higher similarity,and finally the multi-stage image recognition of malaria-infected erythrocytes was completed.Results Validated on the Malaria-MIT dataset,the experimental results show that compared with original model,the proposed method improved accuracy,precision,recall rate and F1-score to 96.18%,96.23%,96.18%and 96.18%,respectively.Conclusion The proposed approach can effectively accomplish the task of multi-stage image recognition of malaria-infected erythrocytes.
