Objective To examine the effect of patient-centered care services on compliance to treatment among patients with multidrug-resistant (MDR) or rifampicin-resistant (RR) pulmonary tuberculosis (PTB), so as to provide the scientific evidence for promoting the widespread application of the appropriate nursing process of MDR/RR-PTB patients in the hospital. Methods The MDR/RR-PTB patients that were definitely diagnosed at the Sixth People’s Hospital of Nantong City during the period from January 2017 to October 2020 were enrolled. The patients with confirmed diagnosis of MDR/RR-PTB during the period January 2017 to December 2018 served as controls, who were given routine care in the hospital, and those with confirmed diagnosis of MDR/RR-PTB during the period January 2019 to October 2020 served as the care group, who were given patient-centered personalized care services, including one-to-one consultations, periodic group activities, informatization case management, and personal reminder for return visits. The proportion of inclusion into treatment, loss to follow-up, return visits and sputum examinations were compared between the care and control groups. Results A total of 104 MDR/RR-PTB patients were included, including 54 cases in the control group and 50 cases in the care group. There was no significant difference in gender and age distribution between the two groups (χ² = 3.013, 1.336, P > 0.05). The proportion of inclusion into treatment was higher in the care group (100.00%, 50/50) than in the control group (87.04%, 47/54) (P = 0.013), and the proportion of loss to follow-up was lower in the care group (0, 0/43) than in the control group (19.05%, 8/42) (P = 0.002). In addition, the overall proportion of return visits was higher in the care group (93.09%, 377/405) than in the control group (83.56%, 371/444) (χ² = 18.345, P < 0.001), and the proportion of sputum examinations was higher in the care group was (83.70%, 339/405) than in the control group (79.28%, 352/444) (χ² = 2.737, P = 0.098). Conclusion Patient-centered care services facilitate the improvements in the proportion of inclusion into treatment and compliance to treatment and reduction in the proportion of loss to follow-up among MDR/RR-PTB patients, which deserves widespread applications.

Objective To explore the process and main behavior characteristics of behavioral characteristics of patients with recurrent hypoglycemia in the degeneracy of blood glucose management.Methods A mixed-method convergent design was used to collect data.From June 2022 to April 2023,382 patients with recurrent hypoglycemia were admitted to the endocrine department of a tertiary hospital in Jiangsu were recruited to score of ego depletion.K-means clustering was conducted to analyze the distribution characteristics of patients'characteristics in blood glucose management.At the same time,19 patients who were selected from the participants of the quantitative study were recruited to attend semi-structured interviews.Results Quantitative results analysis:the average score of blood glucose management loss was(49.20±6.58),and the average scores of cognitive control,behavioral control and emotional control were(17.90±4.12),(15.49±3.64)and(15.81±3.58),respectively.The results of cluster analysis showed that behavioral characteristics could be divided into 3 groups:a cognitive depletion group,an emotional depletion group and a self-control group.Qualitative data analysis:the process of deterioration of management in patients included 3 major themes,including the antecedents of ego depletion,the process of ego depletion and the aftereffects of ego depletion.Analysis of the mixed results showed that the status of ego depletion is serious;patients ignore the behavioral elements of active participation in blood glucose management,show many irrational decision-making behaviors,and the degradation behavior characteristics of patients'blood glucose management are different.Conclusion The degeneration behavior of blood glucose management was serious and affected by single or multiple factors,continuously consuming self-control energy and causing ego depletion.To promote the long-term maintenance of blood glucose management,priority should be given to take actions to enhance patients'perceptions,emotion and behaviors,help them learn about the possible blood glucose changes,improve their understanding and recognition of the value of scientific management.

Objective To understand the status and influencing factors of kinesiophobia in patients with diabetic peripheral neuropathic pain(DPNP).Methods From February to June 2023,192 patients with DPNP in a tertiary general hospital in Nanchang City,Jiangxi Province were selected by convenience sampling method.The patients were investigated by the demographic information questionnaire,Tampa Scale for Kinesiophobia,Numerical Rating Scale,Medical Coping Modes Questionnaire,Diabetes Distress Scale,and Summary of Diabetes Self-care Activities.Multiple linear regression were used to analyze the influencing factors of kinesiophobia in patients with DPNP.Results The score of kinesiophobia in patients with DPNP was(36.68±3.88),and the incidence of kinesiophobia was 38.5％.Multiple linear regression analysis showed that marital status,pain level,coping style,diabetic distress and self-management behavior were influential factors for kinesiophobia in patients with DPNP(all P＜0.05).Conclusion Patients with DPNP have a moderate level of kinesiophobia.Nursing staff should pay attention to the early assessment of patients'kinesiophobia,promptly identify and take effective measures to reduce the level of patients'kinesiophobia,increase their motivation to exercise,and improve their prognosis and quality of life.

Objective:To explore the effect of multidisciplinary team cooperation intervention model on the fear of falling (FOF) of postoperative elderly patients during hospitalization.Methods:From January to December 2021, 100 elderly patients with FOF after surgery in the Surgical Ward of the International Medical Department of Peking Union Medical College Hospital were selected by convenient sampling. The patients were randomly divided into the control group and the observation group according to single and double numbers, with 50 cases each. The control group was given routine nursing, and the observation group was given multidisciplinary team cooperation intervention on the basis of routine nursing. The scores of the Modified Fall Efficacy Scale (MFES) were evaluated on the afternoon of the first day of the patient's getting out of bed (inclusion criteria) and the afternoon of the second day of the activity to compare the FOF of the two groups of elderly patients.Results:Before intervention, there was no statistical difference in MFES scores between the two groups ( P>0.05) . After intervention, the MFES score of the observation group was higher than that of the control group, and the difference was statistically significant ( P<0.01) . In the same Morse fall risk grade of low risk, medium high risk and high risk, the difference of MFES score in the observation group was higher than that in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Multidisciplinary team cooperation intervention can effectively improve the FOF of elderly patients during hospitalization after surgery and promote postoperative rehabilitation.

Objectives:To investigate the clinical and genetic features of young Chinese patients with myeloproliferative neoplasms (MPN) .Methods:In this cross-sectional study, anonymous questionnaires were distributed to patients with MPN patients nationwide. The respondents were divided into 3 groups based on their age at diagnosis: young (≤40 years) , middle-aged (41-60 years) , and elderly (>60 years) . We compared the clinical and genetic characteristics of three groups of MPN patients.Results:1727 assessable questionnaires were collected. There were 453 (26.2%) young respondents with MPNs, including 274 with essential thrombocythemia (ET) , 80 with polycythemia vera (PV) , and 99 with myelofibrosis. Among the young group, 178 (39.3%) were male, and the median age was 31 (18-40) years. In comparison to middle-aged and elderly respondents, young respondents with MPN were more likely to present with a higher proportion of unmarried status (all P<0.001) , a higher education level (all P<0.001) , less comorbidity (ies) , fewer medications (all P<0.001) , and low-risk stratification (all P<0.001) . Younger respondents experienced headache (ET, P<0.001; PV, P=0.007; MF, P=0.001) at diagnosis, had splenomegaly at diagnosis (PV, P<0.001) , and survey (ET, P=0.052; PV, P=0.063) . Younger respondents had fewer thrombotic events at diagnosis (ET, P<0.001; PV, P=0.011) and during the survey (ET, P<0.001; PV, P=0.003) . JAK2 mutations were found in fewer young people (ET, P<0.001; PV, P<0.001; MF, P=0.013) ; however, CALR mutations were found in more young people (ET, P<0.001; MF, P=0.015) . Furthermore, mutations in non-driver genes (ET, P=0.042; PV, P=0.043; MF, P=0.004) and high-molecular risk mutations (ET, P=0.024; PV, P=0.023; MF, P=0.001) were found in fewer young respondents. Conclusion:Compared with middle-aged and elderly patients, young patients with MPN had unique clinical and genetic characteristics.
