Objective To investigate the cognitive impairment of middle-aged patients with type 2 diabetes mellitus(T2DM). Methods Wechsler adult intelligence scale-Chinese revised edition (WATS-RC) was used as the tool to examine the cognitive function of middle-aged patients with T2DM and the healthy controls in 51 cases. The t-test was used to compare the differences in score between patients and the control group. The patients were divided into two groups with or without cognitive dysfunction. The logistic regression analysis was made for all the variables to confirm risk factors for the cognitive dysfunction in diabetes. Results The WAITS-RC scores of digit-symbol coding test and block design test were much lower(P<0.05) in diabetes versus control group. The other tests showed no significant difference. The cognitive function was negatively correlated with HbA_1>c and HOMA-IR by logistic regression analysis. Conclusions For middle-aged patients with type 2 diabetes, their cognitive functions such as learning ability, analysis and comprehensive capabilities are impaired. The cognitive function is closely related with HbA_1c and HOMA-IR.

Objective:To explore the mediating effect of medication self-efficacy between perceived social support and compliance behavior in young patients with newly treated pulmonary tuberculosis under the Southern Xinjiang Model.Methods:A cross-sectional survey was conducted in Kashgar Tuberculosis Prevention and Control Institute Hospital and Tuberculosis Specialist Hospital of Hetian from January 2022 to April 2023. A total of 302 young patients with initial treatment of pulmonary tuberculosis in were selected as the research objects by convenience sampling method. The General Information Questionnaire, the Tuberculosis Compliance Behavior Rating Scale, Perceived Social Support Scale and Self-efficacy for Appropriate Medication Use scale were used to investigate, and the correlation analysis and mediating effect analysis were carried out.Results:The total scores of compliance behavior, self-efficacy and perceived social support were (119.09 ± 13.49), (23.48 ± 6.25) and (55.67 ± 11.33) respectively. All dimensions of medication self-efficacy and perceived social support were positively correlated with compliance behavior ( r values were 0.555 - 0.943, all P<0.01), and medication self-efficacy was positively correlated with perceived social support ( r = 0.981, P<0.01). Medication self-efficacy played a partial mediating effect between perceived social support and compliance behavior, accounting for 74.46% of the total effect. Conclusions:The medication self-efficacy of young patients with newly treated pulmonary tuberculosis is the mediating variable between perceived social support and compliance behavior. Medical staff should focus on and carefully evaluate the medication self-efficacy and perceived social support of patients, so as to give supportive intervention in time, so as to change or even reverse the non-compliance behavior and improve the compliance level of patients.

Objective:To investigate the medication adherence and its influencing factors in young newly diagnosed pulmonary tuberculosis patients during different treatment periods, in order to provide a theoretical basis for formulating precise medication management strategies and thus improving the treatment success rate.Methods:A cross-sectional survey was conducted using a stratified random sampling method to select 283 young newly diagnosed pulmonary tuberculosis patients who visited and registered in the Kashgar region of Xinjiang from September 2021 to February 2022. The patients were divided into three groups according to the treatment time of receiving standard chemotherapy regimen: A (1-2 months of medication), B (3-4 months of medication), and C (5-6 months of medication), with 77, 89, and 117 cases, respectively. The clinical data of tuberculosis patients were collected by using the general information questionnaire,Eight-Item Morisky Medication Adherence Scale and Tuberculosis Medication Adherence Scale for tuberculosis patients.Results:Those who take medication well of three groups of young newly treated pulmonary tuberculosis patients were 93.5% (72/77), 89.9% (80/89), and 82.1% (96/117), respectively. The difference among the three groups was statistically significant ( χ2=6.23, P<0.05). Logistic regression analysis showed that social support was an influential factor for the 1st to 2nd month of medication ( OR=0.536, P<0.05); treatment confidence and psychological status were influential factors for the 3rd to 4th month of medication ( OR=0.668, 2.212, both P<0.05); comorbidity, social support, psychological status, and coping style were influential factors for the 5th to 6th month of medication ( OR values were 0.428 - 9.518, all P<0.05). Conclusions:The relevant factors that affect medication adherence vary among young newly diagnosed pulmonary tuberculosis patients at different stages of treatment. Accurate medication management strategies should be developed based on the influencing factors at each stage.
