Learning effect of online versus onsite education in health and medical scholarship - protocol for a cluster randomized trial.

BACKGROUND: The disruption of health and medical education by the COVID-19 pandemic made educators question the effect of online setting on students' learning, motivation, self-efficacy and preference. In light of the health care staff shortage online scalable education seemed relevant. Reviews on the effect of online medical education called for high quality RCTs, which are increasingly relevant with rapid technological development and widespread adaption of online learning in universities. The objective of this trial is to compare standardized and feasible outcomes of an online and an onsite setting of a research course regarding the efficacy for PhD students within health and medical sciences: Primarily on learning of research methodology and secondly on preference, motivation, self-efficacy on short term and academic achievements on long term. Based on the authors experience with conducting courses during the pandemic, the hypothesis is that student preferred onsite setting is different to online setting. METHODS: Cluster randomized trial with two parallel groups. Two PhD research training courses at the University of Copenhagen are randomized to online (Zoom) or onsite (The Parker Institute, Denmark) setting. Enrolled students are invited to participate in the study. Primary outcome is short term learning. Secondary outcomes are short term preference, motivation, self-efficacy, and long-term academic achievements. Standardized, reproducible and feasible outcomes will be measured by tailor made multiple choice questionnaires, evaluation survey, frequently used Intrinsic Motivation Inventory, Single Item Self-Efficacy Question, and Google Scholar publication data. Sample size is calculated to 20 clusters and courses are randomized by a computer random number generator. Statistical analyses will be performed blinded by an external statistical expert. DISCUSSION: Primary outcome and secondary significant outcomes will be compared and contrasted with relevant literature. Limitations include geographical setting; bias include lack of blinding and strengths are robust assessment methods in a well-established conceptual framework. Generalizability to PhD education in other disciplines is high. Results of this study will both have implications for students and educators involved in research training courses in health and medical education and for the patients who ultimately benefits from this training. TRIAL REGISTRATION: Retrospectively registered at ClinicalTrials.gov: NCT05736627. SPIRIT guidelines are followed.

Lung cancer: a nationwide analysis of sex and age incidence trends from 1980 to 2022.

BACKGROUND: Lung cancer, once rare, has evolved into the global leading cause of cancer-related mortality, primarily driven by widespread cigarette smoking in the 20th century. This study explores the historical trends of lung cancer incidence in Denmark over four decades, emphasizing the impact of smoking prevalence, age, and gender on the observed patterns. MATERIALS AND METHODS: Drawing upon data from the Danish National Patient Register and information on smoking habits provided by the Danish Health Authority, this study investigates lung cancer incidence rates, demographic shifts, and smoking prevalence from 1980 to 2022. RESULTS: Smoking prevalence exhibited a consistent decline in males from 1950 to 2022, whereas female smoking prevalence maintained a stable level from 1950 to 1987, followed by a subsequent decline from 1987 to 2022. A peak in lung cancer crude incidence rates was identified during 2014-2017, with no significant difference observed before and after this period. Over the period, the gender distribution transitioned from a male majority to an equal male-female ratio, and age-specific disparities indicated declines in patients aged 50-59 and increases in those above 80 years. INTERPRETATION: The certainty of a decline in lung cancer incidence in the coming years remains unclear. Based on smoking prevalence, it might still be a decade away. To ensure a sustained decline in lung cancer incidence, targeted interventions are imperative, including customized smoking cessation programs that could be designed favorably for females. Given the modest decline in smoking prevalence over the last decade, legislation aimed at discouraging young individuals from smoking is pivotal. As of now, these efforts have not been implemented in Denmark.

Preferences for Follow-Up Procedures among Patients Lost to Follow-Up after Smoking Cessation Intervention among Therapists-An Interview Study.

Achieving high follow-up rates after smoking cessation interventions (SCIs) is a general challenge. The aim of this study was to identify preferences among patients and therapists for improving follow-up rates and to assess smoking status at 6 months among patients lost to follow-up. From the Danish STOPbase for Tobacco and Nicotine, which collects data on SCI across health care, 20 representative patients lost to follow-up by routine procedures were identified together with 11 therapists. All participated in individual semi-structured phone interviews, which for patients also included 6-month smoking status. Deductive and inductive analyses were performed. Four themes emerged from the analyses with several subthemes, all regarding contacts. Both patients and therapists preferred to intensify the follow-up process by boosting it with additional attempts and using voice messages, e-mail and/or SMS, calling at specified times of the day and avoiding calls from unknown numbers. In addition, some patients mentioned that they were busy or were not carrying their mobile devices at the time of a call as a barrier. Some therapists mentioned that barriers could include an expectation of relapse, but also a poor mental state, the time of day and patient fear of public systems. Among the patients originally lost to follow-up, 35% (95% CI 16%-59%) experienced continuous smoking cessation for 6 months, and the overall national rate was 22% (21.6-23.3%). In conclusion, both patients and therapists preferred intensified follow-up. The 6-month smoking status for patients lost to follow-up seemed to be similar to that of the routinely followed-up patients. These findings will be examined experimentally in a larger study.

Identification of Alcohol Use Prior to Major Cancer Surgery: Timeline Follow Back Interview Compared to Four Other Markers.

BACKGROUND: The postoperative complication rate is 30-64% among patients undergoing muscle-invasive and recurrent high-risk non-muscle-invasive bladder cancer surgery. Preoperative risky alcohol use increases the risk. The aim was to evaluate the accuracy of markers for identifying preoperative risky alcohol. METHODS: Diagnostic test sub-study of a randomized controlled trial (STOP-OP trial), based on a cohort of 94 patients scheduled for major bladder cancer surgery. Identification of risky alcohol use using Timeline Follow Back interviews (TLFB) were compared to the AUDIT-C questionnaire and three biomarkers: carbohydrate-deficient transferrin in plasma (P-CDT), phosphatidyl-ethanol in blood (B-PEth), and ethyl glucuronide in urine (U-EtG). RESULTS: The correlation between TLFB and AUDIT-C was strong (ρ = 0.75), while it was moderate between TLFB and the biomarkers (ρ = 0.55-0.65). Overall, sensitivity ranged from 56 to 82% and specificity from 38 to 100%. B-PEth showed the lowest sensitivity at 56%, but the highest specificity of 100%. All tests had high positive predictive values (79-100%), but low negative predictive values (42-55%). CONCLUSIONS: Despite high positive predictive values, negative predictive values were weak compared to TLFB. For now, TLFB interviews seem preferable for preoperative identification of risky alcohol use.

Exploring the feasibility of bacteriocins EntK1 and EntEJ97s in treatment of systemic vancomycin resistant enterococci infections in mice.

AIMS: Enterocins K1 and EJ97 have specific antimicrobial activity against Enterococcus faecium and Enterococcus faecalis, respectively. The aim of this study was to investigate the utility of these enterocins for in vivo treatment of systemic enterococcal infections. METHODS AND RESULTS: The antimicrobial effect in blood was analysed and compared against the effect in saline. Colony forming unit counts revealed that the enterocins killed all the bacteria within 1 hour. Additionally, the bactericidal effect against E. faecalis was more rapid in blood, indicating a possible synergy between EntEJ97 and blood. Importantly, no enterocin resistant mutants emerged in these experiments. Injecting the enterocins intraperitoneally in an in vivo mouse model and using fluorescence and minimum inhibitory concentration determination to estimate concentrations of the peptides in plasma, indicate that the enterocins exist in circulation in therapeutic concentrations. Alanine aminotransferase detection, and haemolysis analysis indicates that there is no detectable liver damage or haemolytic effect after injection. CONCLUSIONS: The study revealed that EntK1 and EntEJ97 are able to kill all bacteria ex vivo in the presence of blood. In vivo experiments determine that the enterocins exist in circulation in therapeutic concentrations without causing liver damage or haemolysis. Future experiments should test these peptides for treatment of infection in a relevant in vivo model.

Risky Sexual Behaviour and Sexual Victimization among Young People with Risky Substance Use in Europe-Perspectives from Belgium, Sweden, the Czech Republic, and Germany.

BACKGROUND: Research indicates that among the risks associated with young people's alcohol and illicit drug use are sexual risks. However, insights into co-occurrence of substance use and sexual risks in adolescent samples and possible differences across countries are limited. METHODS: A sample of 1449 adolescents from Belgium, Sweden, the Czech Republic, and Germany screened positive for risky alcohol/illicit drug use in a web-based intervention against alcohol and illicit drug use. They also reported incidents of sex while being drunk and/or high on drugs, condomless sex on these occasions, and sexualized touching and sexual victimization while being drunk or high on drugs. RESULTS: In the sample, 21.5% of the participants reported sexualized touching, 9.9% being victim to sexual assault, and 49.8% having had sex while being drunk and/or high on drugs; of the latter, 48.3% had condomless sex. Reports on having had sex while being drunk and/or high on drugs were associated with higher levels of past 30-day binge drinking. Being a victim of sexual assault was associated with past 30-day binge drinking only in young men. CONCLUSION: When devising preventive interventions against risky substance use in adolescents, an additional focus should be set on integrating steps against sexual risks.

Two novel prehabilitation apps to help patients stop smoking and risky drinking prior to hip and knee arthroplasty.

PURPOSE: Daily smoking or risky drinking increases the risk of complications after surgery by ~50%. Intensive prehabilitation aimed at complete cessation reduces the complication rate but is time-consuming. The purpose of this study was to carry out preoperative pilot tests (randomized design) of the feasibility (1A) and validation (1B) of two novel prehabilitation apps, habeat® (Ha-app) or rehaviour® (Re-app). METHODS: Patients scheduled for hip or knee arthroplasty with daily smoking, risky drinking, or both were randomised to one of the two apps. In part 1A, eight patients and their staff measured feasibility on a visual analog scale (VAS) and were interviewed about what worked well and the challenges requiring improvement. In part 1B, seven patients and their staff tested the improved apps for up to two weeks before validating the understanding, usability, coverage, and empowerment on a VAS and being interviewed. RESULTS: In 1A, all patients and staff returned scores of ≥5 for understanding the apps and mostly suggested technical improvements. In 1B, the scores varied widely for both apps, with no consensus achieved. Two of four patients (Ha-app) and one-third of the patients (Re-app) found the apps helpful for reducing smoking, but without successful quitting. The staff experienced low app competencies among patients and high time consumption. Specifically, patients most often needed help for the Ha-app, and the staff most often for Re-app; however, the staff reported the Re-app dashboard was more user-friendly. Support and follow-up from an addiction specialist staff member were suggested to complement the apps, thereby increasing the time consumption for staff. CONCLUSIONS: This pilot study to test prototype apps generated helpful feedback for the app developers. Based on the patient and staff comments, multiple improvements in functionality seem required before scaling up the evaluation for effect on prehabilitation and postoperative complications.

Neutral natural deep eutectic solvents as anti-biofilm agents.

Natural deep eutectic solvents (NADES) are a class of liquids with promising properties as components in pharmaceutical formulations, such as a low toxicity profile, biodegradability and versatility. Recently, their potential use as anti-biofilm agents has been proposed, due to their ability to solubilize and stabilize biological macromolecules. In the current work, the ability to break down biofilm matrix and the biofilm killing activity of three NADES of neutral pH were investigated against Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 9027 biofilms. The tested NADES were choline chloride:xylitol (ChX), choline chloride:glycerol (ChG) and betaine:sucrose (BS). Two of the NADES (ChX and ChG) significantly reduced the number of remaining viable cells of both bacterial species in pre-formed biofilm by 4-6 orders of magnitude, while the average biofilm biomass removal for all NADES was 27-67% (S. aureus) and 34-49% (P. aeruginosa). The tested NADES also inhibited biofilm formation of both bacterial species at concentrations at or below 0.5 x the minimal inhibitory concentration (MIC), possibly in part due to observed restrictions imposed by NADES on planktonic growth. These results demonstrate the potential value of neutral NADES as anti-biofilm agents in future antimicrobial preparations.

From Targeted Needs Assessment to Course Ready for Implementation-A Model for Curriculum Development and the Course Results.

This article contributes guidance on how to approach the development of a course curriculum in general and presents a specific example from medical research education. The purpose of this study is to discuss a model for translating needs assessments of targeted learners into a course curriculum. The model employs established methods for data collection, such as different interview approaches and surveys. The authors argue that there is value in going from exploratory in-depth qualitative data collection methods to more conclusive rigorous quantitative methods when developing a course curriculum. In this way, the model is especially sensitive to the needs of targeted learners in the initial phase and at the same time offers a systematic and practical approach to curriculum development. The model is presented step-by-step with the aid of an empirical example of how to assess the needs of medical doctors in the publication process and develop an introductory course in writing an initial manuscript for publication. The article concludes that the proposed model gives curriculum developers a unique opportunity to explore the needs of targeted learners in depth, while systematically aiming towards conclusive decisions on curriculum content ready for implementation.

Intensive versus short face-to-face smoking cessation interventions: a meta-analysis.

OBJECTIVES: To evaluate the efficacy of intensive smoking cessation interventions (ISCIs) directly compared with shorter interventions (SIs), measured as successful quitting. METHOD: Medline, Embase, the Cochrane Library and CINAHL were searched on 15 October 2021. Peer-reviewed randomised controlled trials (RCTs) of adult, daily smokers undergoing an ISCI were included. No setting, time or language restrictions were imposed. Risk of bias and quality of evidence was assessed using the Cochrane tool and Grading of Recommendations, Assessment, Development and Evaluation, respectively. Meta-analyses were conducted using a random-effects model. RESULTS: 17 550 unique articles were identified and 17 RCTs evaluating 9812 smokers were included. 14 studies were conducted in Europe or the USA. The quality of the evidence was assessed as low or moderate. Continuous abstinence was significantly higher in ISCIs in the long term (risk ratio 2.60, 95% CI 1.71-3.97). Direction and magnitude were similar in the short term; however, they were not statistically significant (risk ratio 2.49, 95% CI: 0.94-6.56). When measured as point prevalence, successful quitting was still statistically significant in favour of ISCIs, but lower (long term: 1.64, 1.08-2.47; short term: 1.68, 1.10-2.56). Sensitivity analysis confirmed the robustness of the results. CONCLUSION: ISCIs are highly effective compared to SIs. This important knowledge should be used to avoid additional morbidity and mortality caused by smoking.

Contributory Factors for Teen Insomnia Symptoms: A Prospective Cohort Study in Sweden.

Objectives: Insufficient sleep is a public health problem that impacts the mental and physical health of children and adolescents. Complaints of insomnia are particularly pervasive among adolescents. This longitudinal study investigates factors that contribute to teen insomnia symptoms. Design: Five-year prospective follow-up study. Setting: School-based. Participants: A total of 522 children (49.8% girls) aged 9.4 ± 1.3 years at baseline; 14.4 ± 0.7 years at follow-up. Measurements: The dependent variable of insomnia symptoms at follow-up was assessed with the Minimal Insomnia Symptom Scale-Revised. The independent variables at baseline were the perceived family financial situation, tiredness at school, problems waking up, short sleep duration, sleeping difficulties, having a bedroom Television (TV), and time spent with a TV/computer. Multivariate binary logistic regression analyses were used to examine whether the independent variables at baseline predicted insomnia symptoms at follow-up. Results: Perceived quite bad/very bad family financial situation (OR 3.1; CI 1.4-6.7) and short sleep duration (<10 h) (OR 2.3; CI 1.0-5.3) among girls at baseline were associated with insomnia symptoms at follow-up. Having problems waking up among boys at baseline was associated with insomnia symptoms at follow-up (OR 4.9; CI 1.6-14.4). Conclusion: Short sleep duration, problems waking up, and perceived bad family financial situation during childhood were linked with adolescent insomnia symptoms. The sex-based differences in these associations warrant further investigation to effectively mitigate adolescent insomnia.

Smoking Cessation Rates among Patients with Rheumatoid Arthritis and Osteoarthritis Following the 'Gold Standard Programme' (GSP): A Prospective Analysis from the Danish Smoking Cessation Database.

(1) Background: Smoking cessation may be very difficult, even if smoking aggravates the prognosis of a disease, which has been shown to be the case for persons with rheumatoid arthritis (RA). In contrast, an association in patients with osteoarthritis (OA) is still disputed. The primary objective was to compare smokers diagnosed with RA and OA to controls, regarding smoking cessation rates after following the intensive 'Gold Standard programme' (GSP). Secondary objectives included the identification of significant prognostic factors for successful quitting. (2) Methods: In total, 24,652 patients were included in this prospective cohort study, after attending the national GSP for smoking cessation intervention 2006-2016, as registered in the Danish Smoking Cessation Database. Data were linked to the National Patient Register. Hereof, 227 patients (1%) were diagnosed with seropositive RA and 2899 (12%) with OA. Primary outcome was continuous abstinence six months after the planned quitting date. (3) Results: In total, 16,969 (69%) of the patients participated in the follow-up interviews. The adjusted odds ratios for successful quitting were similar to the control group for both RA (1.28, 95% CI: 0.90-1.80) and OA patients (0.92, 0.82-1.03). The outermost, strongest positive factor for successful quitting was compliance, defined as attending ≥75% of the meetings. To a lesser degree, attending an individual intervention was a positive predictor, while being heavy smokers, disadvantaged smokers, women, living with a smoker, and if GSP was recommended by health professionals were negative predictors. (4) Conclusions: The odds ratios for quitting were similar to controls for both RA and OR patients. Additional research is needed to determine effective actions towards increased attendance at the programmes.

STRONG for Surgery & Strong for Life - against all odds: intensive prehabilitation including smoking, nutrition, alcohol and physical activity for risk reduction in cancer surgery - a protocol for an RCT with nested interview study (STRONG-Cancer).

BACKGROUND: There is a large unused potential for risk reduction in the preoperative period via effective lifestyle intervention targeting co-existing risky lifestyles: Smoking, malNutrition, obesity, risky Alcohol intake and insufficient Physical activity (SNAP). This trial compares the efficacy of the integrated STRONG programme with standard care on preoperative risk reduction and secondly on SNAP factor improvement and frailty, postoperative complications and quality of life. A nested interview study explores the patient preferences and the multi-perspective view of patients, relatives and health professionals. METHODS: In total, 42 surgical patients with ≥1 SNAP factor are allocated to individually tailored STRONG programme or usual care during adjuvant chemotherapy prior to radical bladder cancer surgery. The STRONG programme has ≥6 weekly sessions with patient education, motivational and pharmaceutical support. It is based on intensive smoking and alcohol cessation interventions reporting perioperative quit rates > 50%. Surgical risk reduction is measured as ≥1 step for 1 or more risky lifestyles on the ASA-score, secondly as having no risky SNAP factors, and as any SNAP improvement. The outcomes are validated by measurements and biomarkers. Postoperative complications are categorised according to the Clavien-Dindo classification. Health-related quality of life is measured by EQ-5D. The patients are followed up after 6 weeks at surgery and 6 weeks and 6 months postoperatively. A representative sample of the participants, their relatives and the clinical staff are interviewed until data saturation. Transcription, triangulated analyses and data management are conducted using NVivo computer software. DISCUSSION: The surgical agenda is characterised by fixed dates for surgery focusing on clear risk reduction within a short time. This requires a clinical useful lifestyle intervention programme with a high effect and coverage as well as containing all SNAP factors and tailored to individual needs. The STRONG programme seems to meet these requirements. After development in multi-professional collaboration, STRONG is delivered by a specially trained nurse as part of the surgical patient journey. Overall, this study will bring important new knowledge about risk reduction in a frail patient group undergoing major cancer surgery. TRIAL REGISTRATION: Registration at www.clintrials.gov ( NCT04088968 ) The manuscript form from https://trialsjournal.biomedcentral.com/bmc/journal and the SPIRIT guidelines are followed.

Minor effect of patient education for alcohol cessation intervention on outcomes after acute fracture surgery: a randomized trial of 70 patients.

BACKGROUND AND PURPOSE: High alcohol intake is associated with increased risk of postoperative complications. Alcohol cessation intervention is recommended prior to elective surgery. We investigated short- and long-term effects of perioperative intensive alcohol intervention in relation to acute ankle fracture surgery. PATIENTS AND METHODS: 70 patients requiring ankle fracture surgery and consuming ≥ 21 drinks weekly (1 drink = 12 g ethanol) were randomized to a manual-based 6-week intensive standardized alcohol cessation program, the Gold Standard Program (GSP-A), or treatment as usual (TAU), on the day of operation. GSP-A included 5 personal meetings, patient education, and motivational and pharmacological support (alcohol withdrawal prophylaxis, B vitamins, and low-dose disulfiram). Complications requiring treatment were measured after 6 weeks and 1 year. Alcohol intake was validated by biomarkers. Quality of life (QoL) was measured by the SF-36. Hospital costs were obtained from the National Hospital Costs Register. RESULTS: Postoperatively, complete alcohol cessation was higher in the GSP-A than in the TAU group (18/35 vs. 5/35, number needed to treat = 3, p ≤ 0.001), but not lowrisk consumption in the long term (10/35 vs. 7/33, p = 0.5). Number of complications in the short and long term (12/35 vs. 14/33, 16/35 vs. 18/33), the SF-36 score, or hospital costs in the short and long term (€6,294 vs. €8,024, €10,662 vs. €12,198), were similar between the groups. INTERPRETATION: Despite an effect on alcohol cessation and a positive tendency as regards the other outcomes, the postoperative complications, QoL, and costs were similar. Better perioperative strategies for acute surgical patients with high alcohol intake therefore need to be developed.

Effect of a Smoking and Alcohol Cessation Intervention Initiated Shortly Before Radical Cystectomy-the STOP-OP Study: A Randomised Clinical Trial.

BACKGROUND: Evidence concerning the reduction of postoperative complications due to smoking and alcohol drinking in patients undergoing radical cystectomy is incomplete. OBJECTIVE: To evaluate the efficacy of a 6-wk smoking and/or alcohol cessation intervention, initiated shortly before surgery and continued until 4 wk after, in reducing complications. DESIGN, SETTING, AND PARTICIPANTS: Between 2014 and 2018, we enrolled 104 patients with high-risk bladder cancer who were daily smokers or consuming at least 3 units of alcohol daily in a multicentre randomised clinical trial. INTERVENTION: Patients were randomised to a 6-wk intensive smoking and/or alcohol cessation intervention or treatment as usual. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was the number of patients developing any postoperative complication, or death, within 30 d after surgery. The secondary endpoints were successful quitters, health-related quality of life, length of stay, time back to habitual activity, and mortality. An intention-to-treat analysis was applied to evaluate treatment effect. RESULTS AND LIMITATIONS: There were some differences in baseline demographic and lifestyle characteristics. Postoperatively, 64% in the intervention group versus 70% in the control group (risk ratio [RR] 0.91, confidence interval [CI] 0.68-1.21, p = 0.51) developed complications. Significantly fewer patients developed three or more complications after 30 d (RR 0.39; CI 0.18-0.84, p = 0.01). The rates of successful quitting were 51% in the intervention group and 27% in the control group (RR 2, CI 1.14-3.51, p = 0.01). The external validity of this trial may be limited because 53% of eligible patients refused participation. CONCLUSIONS: Despite a significant effect on the quit rate at completion of the intervention, this multimodal prehabilitation did not show a significant difference regarding our primary outcome postoperative complications. PATIENT SUMMARY: A 6-wk smoking and alcohol cessation intervention in relation to bladder cancer surgery did not reduce postoperative complications, but it was effective in supporting people to quit in the short term.

Effectiveness of tobacco cessation interventions for different groups of tobacco users in Sweden: a study protocol for a national prospective cohort study.

INTRODUCTION: Tobacco is still one of the single most important risk factors among the lifestyle habits that cause morbidity and mortality in humans. Furthermore, tobacco has a heavy social gradient, as the consequences are even worse among disadvantaged and vulnerable groups. To reduce tobacco-related inequity in health, those most in need should be offered the most effective tobacco cessation intervention. The aim of this study is to facilitate and improve the evaluation of already implemented national tobacco cessation efforts, focusing on 10 disadvantaged and vulnerable groups of tobacco users. METHODS AND ANALYSIS: This is a prospective cohort study. Data will be collected by established tobacco cessation counsellors in Sweden. The study includes adult tobacco or e-cigarette users, including disadvantaged and vulnerable patients, receiving in-person interventions for tobacco or e-cigarette cessation (smoking, snus and/or e-cigarettes). Patient inclusion was initiated in April 2020. For data analyses patients will be sorted into vulnerable groups based on risk factors and compared with tobacco users without the risk factor in question.The primary outcome is continuous successful quitting after 6 months, measured by self-reporting. Secondary outcomes include abstinence at the end of the treatment programme, which could be from minutes over days to weeks, 14-day point prevalence after 6 months, and patient satisfaction with the intervention. Effectiveness of successful quitting will be examined by comparing vulnerable with non-vulnerable patients using a mixed-effect logistic regression model adjusting for potential prognostic factors and known confounders. ETHICS AND DISSEMINATION: The project will follow the guidelines from the Swedish Data Protection Authority and have been approved by the Swedish Ethical Review Authority before patient inclusion (Dnr: 2019-02221). Only patients providing written informed consent will be included. Both positive and negative results will be published in scientific peer-reviewed journals and presented at national and international conferences. Information will be provided through media available to the public, politicians, healthcare providers and planners as these are all important stakeholders. TRIAL REGISTRATION NUMBER: NCT04819152.

Hybrid hydrogels for bacteriocin delivery to infected wounds.

Superficial infections in chronic wounds can prevent the wound healing process by the development of persistent infections and drug-resistant biofilms. Topically applied antimicrobial formulations with stabilized and controlled release offer significant benefits for the effective treatment of wound infections. Bacteriocins are the antimicrobial peptides (AMPs) produced by bacteria that are viable alternatives to antibiotics owing to their natural origin and low propensity for resistance development. Herein, we developed a hybrid hydrogel composed of Pluronic F127 (PF127), ethylenediaminetetraacetic acid (EDTA) loaded liposomes, glutathione (GSH), and the bacteriocin Garvicin KS (GarKS) referred to as "GarKS gel". The GarKS gel exhibited suitable viscosity and rheological properties along with controlled release behavior (up to 9 days) for effective peptide delivery following topical application. Potent in vitro antibacterial and anti-biofilm effects of GarKS gel were evident against the Gram-positive bacterium Staphylococcus aureus. The in vivo treatment of methicillin resistant S. aureus (MRSA) infected mouse wounds suggested potent antibacterial effects of the GarKS gel following multiple applications of once-a-day application for three consecutive days. Altogether, these results provide proof-of-concept for the successful development of AMP loaded topical formulation for effective treatment of wound infections.

Facilitators and Barriers for Young Medical Doctors Writing Their First Manuscript for Publication.

Although scientific publication is often mandatory in medical professions, writing the first research article for publication is challenging, especially as medical curricula have only a minor focus on scientific writing. The aim was therefore to identify facilitators and barriers experienced by medical doctors writing their first scientific article for publication. An explorative inductive approach made use of semi-structured interviews for collecting data until saturation. Data were analyzed with systematic text condensation. Several barriers were identified: (a) writing in general; (b) writing in English; (c) dealing with content, structure, and presentation; and (d) navigating in the author group. Good supervision in the initial writing phase was a facilitating factor. Medical doctors requested a course in which they could work on their own articles and give feedback to fellow students. They valued skilled lecturers and individual supervision, and they wanted to learn about author instructions, how to present text correctly, and how to sell their core message. Their goal was to create a useful end product and to obtain European Credit Transfer System (ECTS) points. The facilitators and barriers that medical doctors experience when writing their first scientific article for publication and their course requests should be reflected in the learning objectives and content of future courses.

The right to smoke and the right to smoke-free surroundings: international comparison of smoke-free psychiatric clinic implementation experiences.

BACKGROUND: In Scandinavia, people with a severe mental disorder have a reduced life expectancy of 15-20 years compared with the general public. Smoking is a major contributor, and smoke-free policies are increasingly adopted in psychiatric clinics around the world. We compared potential facilitators and barriers among staff and management, for the implementation of smoke-free psychiatric clinics. AIMS: To investigate the attitudes and experiences regarding smoke-free policies among managers and staff involved in the implementation processes of smoke-free psychiatric clinics at hospitals in Malmö (Sweden) and Barcelona (Spain). METHOD: We used a qualitative methodology, with 15 semi-structured interviews. The interviews were conducted with each participant individually, and were subsequently transcribed. The data were analysed with systematic text condensation. RESULTS: There were notable differences in how the smoke-free policies were carried out and experienced, and attitudes regarding the policy changes differed in the two settings. Key differences were the views on the right to smoke in compulsory care and to stay in smoke-free surroundings supported by smoking cessation intervention; the prioritisation of staff facilitation of smoking breaks; and views on smoking and smoke-free psychiatry. In contrast, participants agreed on the importance of staff education and management support. A smoking ban by law and belonging to a network of smoke-free hospitals were also relevant. CONCLUSIONS: Staff education, and support from staff and management for the patients' right to stay in smoke-free surroundings, facilitated successful implementation of smoke-free policies in the psychiatric clinics, whereas supporting the right to smoke was a barrier.
