Objective:To explore the complex network correlation between interoceptive sensitivity and sleep quality in colorectal cancer patients with colostomy, clarify core symptoms and bridging symptoms, so as to provide theoretical support for developing targeted intervention measures.Methods:Convenience sampling method was used to select 287 colorectal cancer patients with colostomy at Shanxi Province Fenyang Hospital and Lyuliang First People's Hospital between October 2023 and November 2024 as study subjects. Patients were assessed using the General Information Questionnaire, Multidimensional Assessment of Interoceptive Awareness Version 2-Chinese, and Pittsburgh Sleep Quality Index. Network analysis was employed to investigate the network correlation between interoceptive sensitivity and sleep quality, as well as the characteristics of core nodes. A total of 287 questionnaires were distributed, and 281 effective questionnaires were collected, with an effective response rate of 97.91% (281/287) .Results:Network analysis revealed that the strongest connection weights linking interoceptive sensitivity to sleep quality were observed between trust and daytime dysfunction (connection weight: -0.20), followed by trust and sleep duration (connection weight: -0.10). The strength, betweenness, and closeness of trust centrality indicators were 1.24, 2.34, and 1.73, respectively. Trust emerged as the core node within the interoceptive sensitivity cluster. The strength, betweenness, and closeness of daytime dysfunction indicators were 1.15, 1.92 and 1.67. Daytime dysfunction emerged as the core node within the sleep quality cluster. Trust served as a bridging role in the complex network correlation between interoceptive sensitivity and sleep quality.Conclusions:There is a strong correlation between trust and daytime dysfunction and sleep duration among colorectal cancer patients with colostomy. Trust is a key factor in the network correlation between interoceptive sensitivity and sleep quality. Clinical healthcare providers can develop targeted interventions based on trust to improve the interoceptive sensitivity and sleep quality of colorectal cancer patients with colostomy.

Objective To analyze the influencing factors and action paths of frailty in elderly patients with col-orectal cancer,so as to provide a theoretical clinical intervention.Methods A convenience sampling method was adopted.A total of 254 elderly patients with colorectal cancer who were scheduled for elective surgery in a tertiary A hospital in Shanxi Province from March 2023 to September 2024 were selected as the research subjects.General information questionnaires,Fried frailty phenotype,Perceived Ageism Scale,Multidimensional Assessment Scale of In-teroceptive Awareness Version 2-Chinese,Cancer Patient Self-Management Assessment Scale,and Anderson Symptom Inventory were used for the investigation,and a structural equation model was constructed.Results The incidence of frailty in elderly colorectal cancer patients before surgery is 38.98％.Anderson Symptom Assessment and Per-ceived Ageism were positively correlated with frailty(r=0.534,0.568,P＜0.01),while interoceptive sensitivity and the self-management level were negatively correlated with frailty(r=-0.444,-0.659,P＜0.01).Self-management behavior had only a direct effect on patients' frailty(β=-0.349,P＜0.001),while Anderson Symptom Assessment,perceived age discrimination and interoceptive sensitivity had both direct and indirect effects on patients' frailty(direct effects β=0.235,0.287,-0.220;indirect effects β=0.147,0.090,-0.113;all P＜0.001).Conclusion The incidence of frailty in elderly patients with colorectal cancer before surgery is high.Attention should be paid to patients who are elderly,female and have a low level of education.Medical staff can take targeted measures to enhance patients' interocep-tive concentration and stability,so that patients can better monitor and regulate their bodies and emotions,and im-prove their health-promoting decisions and behaviors.At the same time,attention should also be paid to the prob-lem of age discrimination to create a good medical environment for patients.

BACKGROUNDAn zidovudine (AZT)-substitution regimen containing 24-week stavudine (d4T) followed by long-term AZT for HIV therapy is potential to trade off short-term AZT-related anemia and long-term risks associated with d4T in resource-limited settings. However, evidence is scarce. This study aims to assess the efficacy and safety of AZT-substitution regimen, aiming to find a regimen with better efficacy, less adverse events, and more affordability in resource-limited settings.

METHODSThis prospective, multicenter study enrolled 499 (190 on d4T regimen, 172 on AZT regimen, and 137 on AZT-substitution regimen) HIV-1-infected subjects who initiated combined antiretroviral therapy and attended follow-up visits over 96 weeks from 2009 to 2011. Lamivudine (3TC) and either nevirapine (NVP) or efavirenz (EFV) were the other two drugs in the antiretroviral regimens. Virologic and immunologic responses and adverse events were monitored at baseline and at weeks 4, 12, 24, 36, 48, 60, 72, 84, and 96.

RESULTSIn terms of hematological adverse effects, AZT-substitution group had similar safety profiles to d4T group and was superior to AZT group. In comparison with AZT-substitution group, AZT group was associated with higher risk of developing anemia (adjusted hazard ratio (aHR) for anemia ≥ grade II, 8.44, 95% CI 1.81-39.46) and neutropenia (aHR for neutropenia ≥ grade II, 1.86, 95% CI 1.19-2.93). The prevalence of lipodystrophy in d4T group was 19.5%, while that in AZT-substitution group was zero. As to antiretroviral efficacy, these three groups showed no differences.

CONCLUSIONAZT-substitution regimen provides a relatively safe and effective first-line antiretroviral strategy in resource-limited settings.
