Objective:To explore different types of psychological reactions of spouses of young and middle-aged breast cancer patients and their influencing factors based on potential profile analysis, so as to provide reference for targeted intervention in clinical practice.Methods:A cross-sectional investigation method was used to select the spouses of middle-aged and young patients with breast cancer who were hospitalized in the Second Affiliated Hospital of Guilin Medical University, Quanzhou County People's Hospital, and Bobai County People's Hospital from January 2023 to June 2024. General Data Questionnaire, Spousal Psychological Response Scale of Breast Cancer Patients, Perceived Partner Responsiveness Scale and Perceptive Social Support Scale were used to investigate. The potential profile analysis of spousal psychological reaction of young and middle-aged breast cancer patients was carried out, and the influencing factors of different categories were analyzed by ordered multiple Logistic regression.Results:A total of 232 questionnaires were distributed, and 211 valid questionnaires were collected, with an effective response rate of 91.0%.The spouses of 211 middle-aged and young patients with breast cancer were 30-59 (43.25 ± 2.58) years old. The total psychological response score was (69.96 ± 8.36). The low psychological response high coping group accounted for 24.6% (52/211), the moderate psychological response group accounted for 33.2% (70/211), and the high psychological response low coping group accounted for 42.2% (89/211). The results of ordered multiple Logistic regression analysis showed that cumulative care time, tumor stage of patients, perceived partner responsiveness, and perceived social support were the influencing factors of potential categories of psychological responses of spouses of young and middle-aged breast cancer patients ( OR values were 0.014-0.304, all P<0.05). Conclusions:There is heterogeneity in the psychological reactions of spouses of young and middle-aged breast cancer patients. According to the characteristics of the classification, the nursing staff should formulate targeted intervention strategies, focusing on improving the perceived partner responsiveness, establishing an effective social support system, and reducing the level of psychological response.

Objective:To explore the chain mediating effect of coping style and illness perception between intolerance of uncertainty and fear of disease progression in patients with intracranial aneurysm.Methods:A total of 270 patients with intracranial aneurysms admitted to the neurosurgery department of 2 hospitals in Guangzhou from October 2023 to June 2024 were selected by convenience sampling method. The general information questionnaire, intolerance of uncertainty scale-12, the brief disease perception questionnaire, medical coping mode questionnaire(MCMQ) and fear of progression questionnaire-short form were used to investigate the subjects. Statistical description and Spearman correlation analysis were performed using IBM SPSS 25.0 software, and AMOS 23.0 software was used to test and correct the structural equation models.Results:The total score of fear of disease progression in patients with intracranial aneurysms was 27.50(20.00, 34.00). The total score of intolerance of uncertainty was 23.50(19.75, 29.00). The sores of confrontation, avoidance and submission in MCMQ were 18.69±5.44, 12.00(10.00, 15.00) and 7.00(5.00, 9.00), respectively.The total score of illness perception was 37.23±11.60. Fear of disease progression was positively correlated with intolerance of uncertainty, submission and illness perception ( r=0.614, 0.696, 0.680, all P<0.01). The direct effect of intolerance of uncertainty on fear of disease progression was significant in patients with intracranial aneurysms ( β=0.431, P<0.001). Intolerance of uncertainty indirectly affected fear of disease progression through submission ( β=0.181, P<0.001) and illness perception ( β=0.092, P<0.001). Submission and illness perception played chain-mediating effect in the relationship between intolerance of uncertainty and fear of disease progression ( β=0.103, P<0.001). Conclusion:The intolerance of uncertainty in patients with intracranial aneurysms can positively predict the fear of disease progression. Submission and illness perception played a chain mediating role between intolerance of uncertainty and fear of disease progression in patients with intracranial aneurysms.

Objective:To compare the efficacy and safety of crisaborole ointment 2% versus pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged 2 years or older.Methods:A multicenter, randomized, open-label, controlled clinical trial was conducted. A total of 120 pediatric patients aged 2 - 17 years with mild to moderate atopic dermatitis were enrolled from departments of dermatology of 8 hospitals in China between March 2022 and February 2023. The participants were randomly assigned in a 1∶1 ratio to the crisaborole group and the pimecrolimus group, and received the treatment with crisaborole ointment 2% and pimecrolimus cream 1% respectively, twice a day for 4 weeks. Visits were scheduled at baseline/on day 1, as well as on days 8, 15, and 29. The primary efficacy outcome was the percentage of patients achieving the Investigator's Static Global Assessment (ISGA) success (defined as clear [0] or almost clear [1] on the ISGA scale, combined with ≥ 2‐grade improvement from baseline) on day 29. The secondary efficacy outcomes included changes in the Eczema Area and Severity Index (EASI) total scores from baseline to day 29, percentages of patients achieving ISGA improvement (defined as clear [0] or almost clear [1] on the ISGA scale), as well as changes in the Peak Pruritus Numerical Rating Scale (NRS) scores, Dermatology Life Quality Index (DLQI) /Infants' Dermatology Life Quality Index (IDLQI) /Children's Dermatology Life Quality Index (CDLQI) scores, and in the Dermatitis Family Impact (DFI) scores. Drug safety was evaluated according to the incidence of adverse events. Categorical data were compared using the chi-square test. Since measurement data did not follow a normal distribution, the rank sum test was used for comparisons of measurement data between groups.Results:A total of 106 children with mild to moderate atopic dermatitis were included in the per-protocol analysis set, with 52 in the crisaborole group (26 males and 26 females) and 54 in the pimecrolimus group (27 males and 27 females). There were no significant differences in age, disease duration, ISGA and EASI scores at baseline between the two groups (all P > 0.05). On day 29, 22 patients (42.31%) in the crisaborole group and 25 (46.30%) in the pimecrolimus group achieved ISGA success, with no significant difference between the two groups ( χ2 = 0.17, P = 0.68) ; 35 patients (67.31%) in the crisaborole group and 45 (83.33%) in the pimecrolimus group achieved ISGA improvement, also with no significant difference between the two groups ( χ2 = 3.68, P = 0.06) ; additionally, there were no significant differences in the EASI, pruritus NRS, DLQI/IDLQI/CDLQI, or DFI scores between the two groups (all P > 0.05). Adverse reactions to the two topical agents were mainly local reactions such as mild to moderate pain, itching, or worsening of itching, and no obvious systemic adverse reactions occurred. The incidence of drug-related adverse reactions was 46.15% (24 cases) in the crisaborole group and 37.04% (20 cases) in the pimecrolimus group, with no significant difference between the two groups ( χ2 = 0.91, P = 0.34) . Conclusion:The efficacy of crisaborole ointment 2% was comparable to that of pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged ≥ 2 years, and it yielded early and rapid improvement in the quality of life of patients and their families, with good safety and tolerability profiles.

The menopausal age is one of the important menopausal factors, and women of different menopausal ages have different risks of diabetes. This study reviewed the evidence from prospective studies on the association between the age at natural menopause and diabetes risk, both domestically and internationally, and presented its research design and main findings. Advanced menopause, especially premature and early menopause, will increase the risk of diabetes in postmenopausal women. The research on the influence of delayed menopause on the incidence of diabetes is still insufficient. Many factors may modify the association between menopausal age and the risk of diabetes.
