To analyse trends and characteristics of multidrug-resistant (MDR) bacteria over the past 7 years, in relation to patterns of antimicrobial use, to inform rational antimicrobial use and strengthen hospital infection control measures.

Retrospective cohort study.

A large teaching hospital in Tianjin, a major metropolitan city in northern China.

A total of 190 352 inpatients aged >18 years, admitted between 1 January 2017 and 31 December 2023, were included. Patients were eligible if they had complete clinical data and met the five quality control indicators for multidrug-resistant bacteria (QC-MRB), defined in the ‘Hospital Infection Surveillance Specifications’ (WS/T 312–2023). Patients with MDR infections before admission or those with duplicate results from multiple specimens were excluded.

Statistical analysis revealed a detection rate of 12.11% for the five QC-MRB and an incidence rate of 0.20%. The findings also indicated an upward trend in the detection and incidence rates of carbapenem-resistant Enterobacteriaceae, despite a relatively stable rate of antimicrobial use over 7 years. A positive correlation was observed between the incidence of MDR bacteria and the intensity of antimicrobial use within the hospital setting.

The hospital’s bacterial data align with national trends. It established an interdisciplinary management framework for clinical data analysis and prediction of antimicrobial resistance. This approach enhances infection control measures and supports the rational use of antimicrobials.

First, to understand social needs in different mental disorders. Second, to determine patterns of social behaviour for either physical and online encounters in patients with depression.

Sequential qualitative design: (1) exploratory qualitative interview study investigating social needs of mentally disordered patients, followed by (2) qualitative network analysis of patients and healthy controls, analysed using inductive coding and triangulation for data aggregation and network visualisation. Standards for Reporting Qualitative Research (SRQR) were followed.

(1) Professionals from inpatient and outpatient mental health services of psychosomatic medicine, psychotherapy and psychiatry. (2) Patients from outpatient services, healthy controls from various settings.

(1) Nine mental health professionals with seven physicians and two psychological psychotherapists took part in interviews. (2) Network interviews were conducted with 10 patients with a diagnosis of depression given within the past year and nine healthy controls with matching sociodemographic characteristics.

Social relationships influence both the illness history and symptom profile of patients with depression. Patients reported less encounters compared with controls, although the frequency of their encounters was higher. Patients reported positive and trustful, yet more ambivalent relationships. Patients perceived less trust, but more influence on personal well-being by their encounters. Online contacts were described as more superficial by both groups.

Qualitative network analysis reveals patterns of social needs in physical and online encounters and their visualisation allows for direct group comparisons. Biopsychosocial research designs with a larger sample size are recommended. Targeted interventions have to regard the complexity of relationship patterns in physical and online interactions.

Temporomandibular disorders (TMDs) are a group of conditions affecting the temporomandibular joint (TMJ), masticatory muscles and associated structures, often leading to pain, dysfunction and a significant impact on quality of life. Epidemiological studies have estimated that up to 75% of the population in the USA exhibits at least one sign of TMD. Although conservative treatments, such as acupuncture and occlusal splints, have been recommended, evidence for their effectiveness remains inconclusive, and the combined effects of these interventions are not well understood.

This study aims to evaluate the efficacy of an intraoral balance appliance (IBA) combined with standard Korean medicine care, compared to Korean medicine care alone, in patients with chronic, painful TMD with myalgia.

A single-centre, two-arm, parallel, practitioner-blinded and evaluator-blinded, randomised controlled trial with a 1:1 allocation ratio will be designed to test the interventions. 76 patients with TMD with myalgia will be recruited and randomised. The interventions will include manual acupuncture and physical therapy for both groups, with the addition of IBA in the treatment group for 3 weeks. The primary outcomes of the study will be the Numeric Rating Scale (NRS) for pain and discomfort at the final visit at week 4. Secondary outcomes will include overall functional assessment of the TMJ using several scales, as well as evaluations of quality of life, patient satisfaction and AEs.

The recruitment started on 18 July 2024, and 37 patients were included as of 8 July 2025.

Ethical approval is obtained from the Kyung Hee University Korean Medicine Hospital Institutional Review Board (IRB number: KOMCIRB 2023-06-001). The result from this study will be actively disseminated through manuscript publications and conference presentations.

The protocol was registered with the Clinical Research Information Service (CRiS), Republic of Korea, on 30 October 2023, CRiS number KCT0008906 prior to the initiation of the study, and was revised on 7 July 2025 (https://cris.nih.go.kr/cris/search/detailSearch.do?seq=30270&search_page=M&search_lang=&class_yn=).
