Can simply standing upright sharpen our minds? Whereas initial works proposed that standing posture reduces distractor interference in the Stroop task, subsequent replication attempts yielded mixed results. Importantly, previous studies mostly ignored individual fitness factors like BMI, physical activity level, and cardiac measures, which have recently been suggested to explain mixed findings. Here, we addressed these inconsistencies by controlling for such fitness characteristics in N  = 36 healthy adults. Additionally, we expanded upon previous research by examining posture’s influence on previously unexplored space-based cognitive control using the Navon task. We found evidence against an effect of standing posture on Stroop interference, while, in contrast, standing posture significantly improved spatial conflict processing in the Navon task. Most importantly, this effect was fully mediated by enhanced physiological arousal as indexed by reduced HRV, directly supporting the proposed mechanism of how standing influences cognitive control through increased postural demands. Our findings challenge the idea of a unified attentional control system, revealing that posture differentially influences conflict processing depending on its task-specific nature. These insights may advance theoretical understanding and have practical implications: in increasingly sedentary societies, simple changes like standing could selectively enhance certain cognitive functions, improving effective work and learning environments.

Borg’s rating of perceived exertion (RPE) is a widely used psycho-physical tool to assess subjective perception of effort during exercise. We evaluated the association between Borg’s RPE and physiological exercise parameters in a very large population. In this cohort study, 2,560 Caucasian men and women [median age 28 (IQR 17–44) years] completed incremental exercise tests on treadmills or cycle ergometers. Heart rate, blood lactate concentration, and RPE (Borg scale 6–20) were simultaneously measured at the end of each work load. Rating of perceived exertion was strongly correlated with heart rate ( r  = 0.74, p  < 0.001) and blood lactate ( r  = 0.83, p  < 0.001). The mean values for lactate threshold (LT) and individual anaerobic threshold corresponded to an RPE of 10.8 ± 1.8 and 13.6 ± 1.8, respectively. Fixed lactate thresholds of 3 and 4 mmol/L corresponded to RPEs of 12.8 ± 2.1 and 14.1 ± 2.0. Gender, age, coronary artery disease (CAD), physical activity status and exercise testing modality did not influence this association significantly (all p  > 0.05). Borg’s RPE seems to be an affordable, practical and valid tool for monitoring and prescribing exercise intensity, independent of gender, age, exercise modality, physical activity level and CAD status. Exercising at an RPE of 11–13 (“low”) is recommended for less trained individuals, and an RPE of 13–15 may be recommended when more intense but still aerobic training is desired.

Transcatheter aortic valve implantation (TAVI) is increasingly applied for aortic stenosis in elderly patients with impaired mobility and reduced quality of life. These patients may particularly benefit from postinterventional exercise programs, but no randomized study has evaluated the safety and efficacy of exercise in this population. In a prospective pilot study, 30 patients after TAVI (mean age, 81±6 years, 44% female, 83±34 days postintervention) were randomly allocated 1:1 to a training group (TG) performing 8 weeks of supervised combined endurance and resistance exercise or to usual care. The formal primary efficacy end point was between-group difference in change in peak oxygen uptake assessed by cardiopulmonary exercise testing; secondary end points included muscular strength, 6-minute walk distance, and quality of life (Kansas City Cardiomyopathy Questionnaire and Medical Outcomes Study 12-Item Short-Form Health Survey questionnaires). Safety was assessed by documenting training-related adverse events, prosthesis, and renal function. Significant changes in favor of TG were observed for peak oxygen uptake (group difference, 3.7 mL/min per kg [95% CI, 1.1-6.3; P=.007]), muscular strength (bench press, 6 kg [95% CI, 3-10; P=.002]; rowing, 7 kg [95% CI, 3-11; P<.001]; pulldown, 9 kg [95% CI, 4-14; P=.001]; shoulder press, 5 kg [95% CI, 1-8; P=.008]; leg press, 17 kg [95% CI 6-28; P=.005]), components of quality of life (Kansas City Cardiomyopathy Questionnaire physical limitation, 19.2 [95% CI, 4.1-34.2; P=.015]; symptom burden, 12.3 [95% CI, 0.5-24.0; P=.041]; clinical summary, 12.4 [3.4-21.4; P=.009]), but not for other questionnaire subscales and 6-minute walk distance (15 m [95% CI, −23 to 53; P=.428]). Three dropouts unrelated to exercise occurred (TG=2; usual care,=1); prosthesis and renal function were not affected by the exercise intervention. In patients after TAVI, exercise training appears safe and highly effective with respect to improvements in exercise capacity, muscular strength, and quality of life.

Anti-viral immunity continuously declines over time after SARS-CoV-2 infection. Here, we characterize the dynamics of anti-viral immunity during long-term follow-up and after BNT162b2 mRNA-vaccination in convalescents after asymptomatic or mild SARS-CoV-2 infection. Virus-specific and virus-neutralizing antibody titers rapidly declined in convalescents over 9 months after infection, whereas virus-specific cytokine-producing polyfunctional T cells persisted, among which IL-2-producing T cells correlated with virus-neutralizing antibody titers. Among convalescents, 5% of individuals failed to mount long-lasting immunity after infection and showed a delayed response to vaccination compared to 1% of naïve vaccinees, but successfully responded to prime/boost vaccination. During the follow-up period, 8% of convalescents showed a selective increase in virus-neutralizing antibody titers without accompanying increased frequencies of circulating SARS-CoV-2-specific T cells. The same convalescents, however, responded to vaccination with simultaneous increase in antibody and T cell immunity revealing the strength of mRNA-vaccination to increase virus-specific immunity in convalescents. Waning immunity to SARS-CoV-2 is of concern. Here the authors follow spike- and nucleocapsid specific immunity in convalescent individuals for 9 months observing a decline in antibody levels but persisting T cell response. Vaccination approximately 11 months after infection boosts antibody and T cell immunity.

Physical activity is beneficial for individual health, but endurance sport is associated with the development of arrhythmias like atrial fibrillation. The underlying mechanisms leading to this increased risk are still not fully understood. MicroRNAs are important mediators of proarrhythmogenic remodeling and have potential value as biomarkers in cardiovascular diseases. Therefore, the objective of our study was to determine the value of circulating microRNAs as potential biomarkers for atrial remodeling in marathon runners (miRathon study). 30 marathon runners were recruited into our study and were divided into two age-matched groups depending on the training status: elite (ER, ≥55 km/week, n = 15) and non-elite runners (NER, ≤40 km/week, n = 15). All runners participated in a 10 week training program before the marathon. MiRNA plasma levels were measured at 4 time points: at baseline (V1), after a 10 week training period (V2), immediately after the marathon (V3) and 24h later (V4). Additionally, we obtained clinical data including serum chemistry and echocardiography at each time point. MiRNA plasma levels were similar in both groups over time with more pronounced changes in ER. After the marathon miR-30a plasma levels increased significantly in both groups. MiR-1 and miR-133a plasma levels also increased but showed significant changes in ER only. 24h after the marathon plasma levels returned to baseline. MiR-26a decreased significantly after the marathon in elite runners only and miR-29b showed a non-significant decrease over time in both groups. In ER miRNA plasma levels showed a significant correlation with LA diameter, in NER miRNA plasma levels did not correlate with echocardiographic parameters. MiRNAs were differentially expressed in the plasma of marathon runners with more pronounced changes in ER. Plasma levels in ER correlate with left atrial diameter suggesting that circulating miRNAs could potentially serve as biomarkers of atrial remodeling in athletes.

Background Health benefits of the Mediterranean Diet (MD) have been shown in different at-risk populations. A German translation of the Mediterranean Diet Adherence Screener (MEDAS) from the PREvención con DIeta MEDiterránea (PREDIMED) consortium was used in the LIBRE study, investigating effects of lifestyle-intervention on women with BRCA1/2 mutations. The purpose of the present study is to validate the MEDAS German version. Methods LIBRE is a multicentre (three university hospitals during this pilot phase), unblinded, randomized, controlled clinical trial. Women with a BRCA1/2 mutation of age 18 or over who provided written consent were eligible for the trial. As part of the assessment, all were given a full-length Food Frequency Questionnaire (FFQ) and MEDAS at baseline and after 3 months. Data derived from FFQ was compared to MEDAS in order to evaluate agreement or concordance between the two questionnaires. Additionally, the association of dietary intake biomarkers in the blood (β-carotene, omega-3, omega-6 and omega-9 fatty acids and high-sensitivity C-reactive protein (hsCRP)) with some MEDAS items was analyzed using t-Tests and a multivariate regression. Results The participants of the LIBRE pilot study were 68 in total (33 Intervention, 35 Control). Only participants who completed both questionnaires were included in this analysis (baseline: 66, month three: 54). The concordance between these two questionnaires varied between the items (Intraclass correlation coefficient of 0.91 for pulses at the highest and −0.33 for sugar-sweetened drinks). Mean MEDAS scores (sum of all items) were 9% higher than their FFQ counter-parts at baseline and 15% after 3 months. Higher fish consumption (at least 3 portions) was associated with lower omega-6 fatty acid levels ( p  = 0.026) and higher omega-3 fatty acid levels ( p  = 0.037), both results being statistically significant. Conclusions We conclude that the German MEDAS in its current version could be a useful tool in clinical trials and in practice to assess adherence to MD.

Major depression, bipolar disorder, and schizophrenia are severe mental illnesses. Despite receiving psychopharmacological and psychosocial treatments, about half of patients develop a chronic course with residual cognitive and negative symptoms and have a high risk for cardiovascular disease and reduced life expectancy. Therefore, add-on innovative treatment approaches are needed to improve outcome. Aerobic exercise interventions have been shown to improve global functioning, cognition, and negative and depressive symptoms in these patients. The basic mechanism of these exercise-related changes has been reported to be improved brain plasticity, e.g., increased volume of disease-related brain regions such as the hippocampus. The optimal type, duration, and frequency of exercise have not yet been determined and need to be addressed in supervised physical exercise studies. Because of the low physical activity levels, lack of drive related to negative and depressive symptoms, and high prevalence of cardiovascular comorbidities in patients with severe mental illness, besides aiming to improve symptoms of mental illness, exercise interventions should also aim to increase cardiorespiratory fitness, which they should comprehensively assess by direct measurements of maximal oxygen uptake. Based on the recommendations for developing cardiorespiratory fitness by the American College of Sports Medicine, 150 min moderate-intensity training per week or vigorous-intensity exercise training for 75 min per week are appropriate. Most studies have had relatively short intervention periods, so future studies should focus on long-term adherence to exercise by implementing motivational strategies supported by telemedicine and by identifying and targeting typical barriers to exercise in this patient population.

Radiotherapy (RT), a common cancer treatment, unintentionally harms surrounding tissues, including the skin, and hinders wound healing years after treatment. This study aims to understand the mechanisms behind these late-onset adverse effects. We compare skin biopsies from previously irradiated (RT + ) and non-irradiated (RT − ) sites in breast cancer survivors who underwent RT years ago. Here we show that the RT + skin has compromised healing capacity and fibroblast functions. Using ATAC-seq, we discover altered chromatin landscapes in RT + fibroblasts, with THBS1 identified as a crucial epigenetically primed wound repair-related gene. This is further confirmed by single-cell RNA-sequencing and spatial transcriptomic analysis of human wounds. Notably, fibroblasts in both murine and human post-radiation wound models show heightened and sustained THBS1 expression, impairing fibroblast motility and contractility. Treatment with anti-THBS1 antibodies promotes ex vivo wound closure in RT + skin from breast cancer survivors. Our findings suggest that fibroblasts retain a long-term radiation memory in the form of epigenetic changes. Targeting this maladaptive epigenetic memory could mitigate RT’s late-onset adverse effects, improving the quality of life for cancer survivors. The molecular mechanisms underlying the late-onset adverse effects of radiotherapy remain to be explored. Here, the authors observe compromised wound healing capacity in irradiated skin from breast cancer survivors and highlight THBS1 as a key epigenetically primed wound repair-related gene.

Background Although quality-assured oncological exercise therapy (qOET) has proven effective for cancer patients at any stage of treatment and during aftercare, it is not yet incorporated into standard care in Germany and, to the best of our knowledge, in any other country. A collaboration involving eight German research institutions was initiated to investigate the barriers and facilitators to implementation and promote the wider dissemination of qOET for cancer patients across various settings in Germany. Methods The IMPLEMENT project is designed as an exploratory study with a quasi-experimental design and a mixed-methods approach, combining qualitative and quantitative data collection. Institutions involved in the treatment and/or aftercare of cancer patients will be approached to identify key barriers and facilitators of qOET. Based on these findings, a set of implementation strategies (IPS) will be developed, implemented, and evaluated to facilitate the delivery of qOET for cancer patients. We aim to develop a variety of IPS for different contexts: urban settings (e.g. qualifying local aftercare institutions to provide qOET); rural settings (e.g. a hybrid approach for areas with limited access to local qOET services); adult cancer patients (e.g. focussing on patient education); and children and young cancer patients (e.g. offering consultations with training therapy experts). Additionally, interface management, training concepts, digital support, and economic evaluation will be considered to further promote the wider dissemination of qOET. The impact of the IPS will primarily be measured by the reach of qOET, assessed by comparing the number of cancer patients receiving qOET before and after implementation. Discussion The aim of IMPLEMENT is to address key barriers and facilitators for the implementation of qOET in Germany, and to increase the number of cancer patients receiving qOET in the long term. Following the project, successful IPS will be disseminated for broader application. The IMPLEMENT consortium aims to make a significant contribution to the long-term integration of qOET into the standard care of cancer patients in Germany and prospectively for other countries as well.
