Osteoarthritis (OA) commonly affects the ageing population, particularly the hip joint. Total hip arthroplasty (THA) is a frequent procedure that relieves pain and improves mobility, though some patients experience persistent postoperative pain. With rising numbers of THA, optimising perioperative care and pain management is crucial to address the growing clinical burden and improve patient outcomes. Positive treatment expectations have shown promise in enhancing outcomes, especially in pain management. This study implements two strategies to optimise the patient’s treatment expectations, comprising enhanced physician communication and digital social observational learning. We will examine their separate and combined effects on preoperative expectations, negative emotions, postoperative pain, inflammation and function during recovery up to 12 months postoperatively.

This randomised controlled trial (RCT) investigates the impact of augmented physician communication and observational learning on treatment expectations and recovery. Participants (n=200) will be randomised into four groups: treatment as usual (TAU), augmented doctor conversation (aDOC), observational learning video (Video) and a combination of both (aDOC+Video). The aDOC group receives empathic communication and targeted information to strengthen self-efficacy. The Video group watches a model patient demonstrating successful recovery. The combined group receives both interventions. Outcomes will be assessed at multiple time points (4 days preoperatively; 1 and 4 days, 4 weeks and 3, 6 and 12 months postoperatively), including subjective pain ratings, mobility and objective physical function. The primary analysis will compare changes in pain intensity across groups. Secondary outcomes will include functional status, self-efficacy, recovery and systemic inflammatory markers. Statistical analysis involves repeated measures ANOVA and post hoc tests for between-group and within-group comparisons.

Perioperative adverse events increase morbidity and mortality. The rate and severity of complications and the risk for subsequent mortality are increased after high-risk procedures and in elevated-risk patients. Over the past decades, a multitude of prognostic studies identified perioperative risk factors at the population level. However, to allow for the advancement of precision surgery strategies, improved risk prediction on the individual patient level is warranted. Comprehensive, consecutive, multisource, structured, high-quality patient-related and procedure-related data sets, together with thorough follow-up and combined with state-of-the-art machine-learning analyses, are needed to facilitate precise prediction of perioperative complications. Therefore, we designed and currently conduct the Heidelberg Perioperative Deep Data study (HeiPoDD). Here, we report the rationale and design of the HeiPoDD study.

HeiPoDD is a prospective, single-centre, exploratory cohort study aiming to build up a large-scale deep-data base and corresponding biomaterial collection. 1040 adult patients planned for elective high-risk, non-cardiac surgery for any indication at Heidelberg University Hospital, Germany will be included. The obtained study-specific data set includes clinical data, lab values, genome- and proteome analysis as well as plasma, serum and peripheral blood mononuclear cells (PBMC) collected before and at days 1, 3 and 7 postsurgery. Urine samples are collected before and at day 1 postsurgery. Structured follow-up for perioperative complications such as redo-surgery, length of intensive care stay or length of hospital stay is conducted at days 30, 90 and 1 year postsurgery and for disease progression and survival after 3 and 5 years postsurgery. All study data will be transferred to the HeiPoDD registry to allow merging with all available routine clinical data from the hospital information system including imaging studies as well as haemodynamic and respiratory biosignals. Biomaterials will be stored in the HeiPoDD biomaterial bank to allow further analyses.

The trial protocol and amendments were approved by the ethics committee of the University of Heidelberg (S-758/2021). The protocol is registered with the German Clinical Trial Register (DRKS00024625). Participating patients’ data will be recorded only in pseudonymised form. After completion of the study, data collected during the study will be kept on file for up to 30 years. Biomedical samples collected during the study and entered into the biobank will be held for the same amount of time. The findings will be disseminated in peer-reviewed academic journals.

Young-onset type 2 diabetes (YOD), diagnosed before 40 years of age, entails a high disease burden and potential for early dependence on disability benefits. The risk of type 2 diabetes (T2D) varies with socio-economic status and ethnic background, yet the relationship between these factors and age at diagnosis is insufficiently explored. We aimed to study associations between YOD and living on disability benefits, educational level and country background.

Cross-sectional data on 8640 individuals with T2D, linked to data on educational level and country background, were compared with population data from the same residential areas. Similar comparisons were made for data on disability benefits among 3854 individuals of working age (

The risk of being dependent on disability benefits was three times higher in YOD (adjusted incidence rate ratio, aIRR (95% CI) 3.1 (2.7 to 3.5)) and twice as high in later-onset T2D (1.9 (1.8 to 2.1)) as in the general population. People of Norwegian background with low educational levels had threefold higher YOD risk (3.3 (2.4 to 4.4)) than those with a tertiary degree, while people of non-Western backgrounds with low educational levels had a smaller increase in YOD risk (1.5 (1.1 to 2.1)). People of non-Western backgrounds had higher YOD risk than those of Norwegian background (4.2 (3.5 to 5.0)), while people of south Asian background had an even greater relative YOD risk (9.0 (7.3 to 11.0)), threefold higher than for later-onset T2D (3.2 (2.8 to 3.7)).

Lifetime risk of being dependent on disability benefits was substantially higher for individuals with YOD than in later onset T2D. Non-Western and particularly south Asian backgrounds were associated with increased YOD risk. Low education was an important YOD risk factor only for people with Norwegian background.

Treatment of the two billion people with tuberculosis (TB) infection worldwide is crucial to prevent progression to TB disease and thereby prevent further transmission. However, TB is associated with fear and stigma, and knowledge gaps about TB disease are widespread, complicating adherence to treatment. As increasing knowledge about TB can reduce stigma and increase adherence to treatment, we developed an educational film about TB infection and disease. After showing the film to people with TB, our qualitative study aimed to evaluate the film and to explore perceptions, fears and possible knowledge gaps.

We conducted a qualitative study, with in-depth interviews (n=13), at two Infectious Disease Outpatient Departments in Sweden. Included research participants were adults with TB infection or TB disease. After informed consent, the participants watched the film, available in Swedish, English, Somali and Tigrinya. Subsequently, in-depth interviews, using a topic guide, were conducted, transcribed, and a reflexive thematic analysis was performed.

All participants considered the film to be a valuable addition to the written and oral information they had previously received. Identified themes included the perception of TB infection being a deadly, non-curable disease, and many feared being contagious. However, the film challenged these fears and increased the understanding of TB infection being treatable and non-infectious. Another theme revealed that TB-related stigma was experienced in encounters with healthcare professionals in Sweden.

Our educational film was perceived to increase understanding about TB symptoms, transmission and treatment. Implementing the film in Infectious Disease Departments across Sweden may contribute to decreasing stigma and enhancing awareness of the importance of treatment adherence, an outcome that warrants further investigation post-implementation.
