Global Alliance for the Promotion of Physical Activity: the Hamburg Declaration.

Non-communicable diseases (NCDs), including coronary heart disease, stroke, hypertension, type 2 diabetes, dementia, depression and cancers, are on the rise worldwide and are often associated with a lack of physical activity (PA). Globally, the levels of PA among individuals are below WHO recommendations. A lack of PA can increase morbidity and mortality, worsen the quality of life and increase the economic burden on individuals and society. In response to this trend, numerous organisations came together under one umbrella in Hamburg, Germany, in April 2021 and signed the 'Hamburg Declaration'. This represented an international commitment to take all necessary actions to increase PA and improve the health of individuals to entire communities. Individuals and organisations are working together as the 'Global Alliance for the Promotion of Physical Activity' to drive long-term individual and population-wide behaviour change by collaborating with all stakeholders in the community: active hospitals, physical activity specialists, community services and healthcare providers, all achieving sustainable health goals for their patients/clients. The 'Hamburg Declaration' calls on national and international policymakers to take concrete action to promote daily PA and exercise at a population level and in healthcare settings.

Health care professionals' understanding of contraindications for physical activity advice in the setting of stem cell transplantation.

PURPOSE: Most patients receiving a hematopoietic stem cell transplantation (HSCT) are able to tolerate and benefit from physical activity (PA). Therefore, it is important that health care professionals (HCPs) advise patients to perform PA before, during, and after transplantation. By understanding which medical conditions and safety issues are associated with the (non-) promotion of PA, concrete actions and interventions can be planned and implemented. METHODS: Physicians (N = 51), nurses (N = 52), and physical therapists (N = 26) participated in a nationwide cross-sectional online survey. HCPs' understanding of 15 medical conditions as contraindications for PA was assessed. Significant group differences were determined using chi-square analysis. RESULTS: Acute infection was the only condition which was considered as contraindication by all HCPs (62.7%). Cachexia (78%), having a stoma (91%), or port (96.2%), psychological problems (88.4%), and leukopenia (83.3%) were not considered as contraindications. Six conditions were rated inconsistently between the groups, whereas physicians had the least concerns regarding PA. Physicians with an additional training in PA perceived a platelet count of ≤ 50,000/µl significantly less often as contraindication (p < 0.05). CONCLUSION: The large number of potentially-answers especially in nursing staff and physical therapists might reflect caution or uncertainty. There is a clear need for a good multidisciplinary cooperation between all HCPs in order to support patients to confidently engage in PA. Furthermore, education possibilities and evidence-based courses to build knowledge regarding safety concerns should be the standard practice in the setting of HSCT. The investigative nature of the paper indicates that certain trends should be interrogated in a causal-longitudinal design.

Trends in gross body coordination and cardiorespiratory fitness-a hierarchical Bayesian Analysis of 35 000 2nd Graders.

OBJECTIVE: A negative decline of motor competence in children has been observed over the last decades. Though most studies derive their inferences from only two distant points in time and thus neglect to investigate the variability of the temporal trends. METHODS: Between the year 2000 and 2011, 35 018 second graders performed the Körperkoordinationstest für Kinder (KTK), consisting of four items (WB, HH, JS, and MS) and a six minute run test (6MRT). A hierarchical Bayesian regression model with varying intercepts and temporal trends was fitted to the data. Age, sex, and BMI categories were included as input variables. The outcome variables were z-standardized to the initial cohort. RESULTS: In all four KTK items, we observed a yearly decline of -0.020 (95% UI -0.038 to -0.001) for WB, -0.054 (95% UI -0.071, -0.037) for HH, -0.028 (95% UI -0.045 to -0.012) for JS and -0.088 (95% UI -0.108 to -0.067) for MS. For the 6MRT, no trend was identified. Overweight and obese children showed a disadvantage in all tests scores. Negative time interactions were observed for overweight and obese children in HH and JS. A substantial between-city variation for all temporal trends was observed. The predictive validation for all models but MS was successful. CONCLUSION: A general negative decline was confirmed for coordinative abilities but not in cardiorespiratory fitness. For all outcome variables, a substantial between-city variation was observed, highlighting the importance of environmental factors in motor development. Overweight and obese children demonstrated an urgent need for action.

Efficacy of face-to-face behavior change counseling interventions on physical activity behavior in cancer survivors - a systematic review and meta-analysis.

PURPOSE: This systematic review and meta-analysis of randomized controlled trials determines the efficacy of face-to-face behavior change counseling (BCC) interventions on physical activity (PA) behavior in adult cancer survivors at least pre-and immediately post-intervention compared to usual care. Additionally, this review aims to answer the question which behavior change techniques (BCTs) are most effective. MATERIALS AND METHODS: A structured search of the databases Medline, OTseeker, PEDro, the Cochrane Library, and article reference lists was conducted. All trials were critically appraised for methodological quality using the PEDro scale. The BCC interventions were coded using the BCT Taxonomy (v1). Random effect meta-analysis explored between group differences in PA behavior post intervention. Standardized mean differences (SMD) describe effect sizes. RESULTS: Fourteen studies were included, 12 effect sizes within 11 trials were pooled in meta-analysis. The SMD between groups favored the intervention group with a small effect (SMD 0.22; 95% CI 0.11, 0.33; p < 0.0001). The BCTs "graded tasks", "self-monitoring of behavior", "action planning" and "habit reversal" were more frequently coded in more efficacious interventions. CONCLUSION: BCC interventions are effective in increasing PA behavior in cancer survivors. Further research is needed providing details of fidelity assessment and structuring the intervention description by using a BCT taxonomy. Health care professionals should consider our results while awaiting further trial evaluation.Implications for RehabilitationFace-to-face behavior change counseling interventions can significantly increase physical activity behavior in cancer survivors.Although small differences are evident, included trials presented with a broad variety of study components, and characteristics, which limits the interpretation of effective components.The behavior change techniques "Graded tasks", "Action planning", "Habit reversal", and "Credible Source" were used in the trials with a positive effect, but not in the ineffective ones.

Opportunities and Limits in Salvage Surgery in Persistent or Recurrent Head and Neck Squamous Cell Carcinoma.

Except for HPV-induced cancers of the oropharynx, survival rates in patients with squamous cell carcinoma of the head and neck (HNSCC) have not changed substantially over the last decades. Salvage surgery plays an important role where primary treatment was unsuccessful since 50% of advanced-stage patients relapse after nonsurgical primary treatment. Depending on a variety of factors, a considerable number of patients in whom primary treatment was not successful can still be cured by salvage surgery. It is the goal of this review to elucidate these factors with the aim to counsel patients and their relatives realistically about the chances of being cured.

Health Related Studyability-An Approach to Structure Health Promotion Interventions at Universities.

So far, the only existing prerequisite to enter an academic institution is a specific diploma, like a high school diploma, or another comparable certified document. Other requirements may only be a numerus clausus for certain fields of study to pave the bureaucratic way for a prospective student into their university life. The way first year students dive into their first academic experiences is entirely left to themselves. (Soft) Skills and Competences that exceed the expertise of the chosen courses but are essential for this new, and very challenging, chapter of their lives are not taught to them. Therefore, student health promotion for young adults is essential to build and sustain a healthy lifestyle during their academic careers. Nevertheless, it is important to consider not only a student's perspective but also structural and organizational conditions within the academic institutions. The further development of Ilmarinen's concept of workability may help to construct a theoretical and empirically based concept to implement health-promoting conditions for a student health promotion system at universities. Ilmarinen's concept was chosen by the work group in terms of the structure, which may be adapted to a university since it can be seen as a student's workplace.

Impact of the new TNM Staging System (8th edition) on oral tongue cancers.

AIM OF THE STUDY: For tumours of the oral tongue, the most recent 8th edition of the AJCC/UICC staging system has introduced depth of infiltration (DOI) as a novel parameter. With this study we wanted to investigate its impact regarding this risk stratification compared with the preceding 7th edition. METHODS: Between 2008 and 2017, 161 patients of two tertiary referral centres in Switzerland (Kantonsspital St. Gallen and University Hospital Zurich) with T1 N0 or T2 N0 tongue cancers were enrolled in this study. The primary tumours were restaged according to the 8th edition of the TNM classification. Kaplan-Meier curves for overall and disease-specific survival were calculated. RESULTS: According to the 7th edition, of the 161 patients, 102 were staged after surgery as pT1 (stage I) and 59 as pT2 (stage II). According to the 8th edition, 36 patients (22.4%) were re-staged to a higher stage. Of these 36 patients, 8 (22.2%) experienced a recurrence, and 9 (25%) died. In the remaining, not re-staged group, 20 patients (16.0%) experienced a recurrence (p = 0.55) and 14 (11.2%) died (p = 0.025*). The 7th edition showed a statistically significant difference between pT1 and pT2 tumours for overall survival (p = 0.025), but not for disease-specific survival (p = 0.091), whereas the 8th edition was able to well discriminate between pT1, pT2 and pT3 for both overall (pT1 vs pT2, p = 0.016*; pT2 vs pT3, p = 0.031*) and disease-specific survival (pT1 vs pT2, p = 0.037*; pT2 vs pT3, p = 0.023*). CONCLUSION: The recent TNM 8th edition provides a more accurate prediction of overall and disease-specific survival for this subgroup of patients. Hence, a more aggressive treatment should be considered for patients re-staged to pT3 due to depth of infiltration.

Consolidation cetuximab after concurrent triplet radiochemotherapy+cetuximab in patients with advanced head and neck cancer: A randomized phase II study.

BACKGROUND AND PURPOSE: Preclinical data suggest that cetuximab should be continued after end of concurrent radiotherapy+cetuximab due to its efficacy against residual tumor cells in the irradiated tumor bed. Based on this concept the phase II add-on cetuximab (AOC) study was designed. MATERIALS AND METHODS: Altogether 63 patients with advanced head and neck cancer were treated with radiochemotherapy (70 Gy, cisplatin 40 mg/m2 weekly) in combination with concurrent cetuximab (loading dose 400 mg/m2, then 250 mg/m2 weekly). Thereafter patients were randomized to cetuximab consolidation (500 mg/m2 biweekly × 6) or no further treatment. The primary endpoint was the 2-year locoregional control (LRC) rate. As translational research endpoints serum markers were analyzed before and during treatment and CT-based quantitative image analysis (radiomics) was performed. RESULTS: Median follow-up was 24 months. The 2-year LRC rates were 67.9% and 67.7% in the treatment arms with and without consolidation cetuximab, respectively. Higher than median levels of three serum markers were negatively associated with the 2-year LRC rate in the overall patient cohort: Osteopontin, IL8 and FasL2 (p ≤ 0.05). A radiomics model consisting of two radiomics features could be built showing that higher entropy and higher complexity of tumor Hounsfield unit distribution indicates worse LRC (concordance index 0.66). No correlation was found between biological and imaging markers. CONCLUSIONS: There was no evidence that consolidation cetuximab would improve the 2-year LRC rate. Prognostic biological and imaging markers could be identified for the overall patient cohort. Studies with larger patient numbers are needed to correlate biological and imaging markers.

Evaluation of 18F-FDG PET/CT as an early imaging biomarker for response monitoring after radiochemotherapy using cetuximab in head and heck squamous cell carcinoma.

BACKGROUND: To determine whether 18 F-PET/CT is able to identify treatment response as early as 1 week after the end of chemoradiotherapy, whether 18 F-PET/CT can identify prognostic markers concerning progression free survival and can identify patients who need additional consolidation therapy. METHODS: A total of 54 patients with head and neck cancer were prospectively enrolled in this single-center, randomized study from 03/2012-04/2015. Patients underwent FDG-PET/CT imaging at three predefined time points: pretreatment (PET/CT1), 1 week postprimary radiochemotherapy (PET/CT2) and 3 months postprimary radiochemotherapy (PET/CT3). Tumors were assessed quantitatively based on size and glucose uptake (SUVmax) concerning response at each time point. Response assessment was correlated with progression free survival. All patients had a minimum follow-up period of 18 months. Multivariate regression analysis was performed to find independent predictors for progression free survival (PFS). RESULTS: Thirty-two (32) patients (64%) overall remained disease free, 11 patients (22%) had recurrence and 7 patients (14%) had persistent disease. There was no significantly different metabolic parameter ratio found concerning responders and nonresponders at posttreatment (PET/CT2 and 3) time points (P > .05) during clinical follow-up. Multivariate regression analysis demonstrated both SUVmax and diameter assessed at time point PET/CT3 represent independent predictors of progression free survival (PFS). There was also no statistically significant difference in PFS between responders and nonresponders by means of PET/CT2 in both study arms (P > .05). Imaging responders at time point PET/CT3 showed a significantly longer PFS compared to nonresponders after the end of consolidation therapy (P < .01). CONCLUSIONS: Early response of head/neck cancer after radiochemotherapy can be accurately assessed with PET/CT 1 week after RCT. SUVmax and lesion diameter are independent predictors of PFS at time point PET/CT3. PET/CT2 has no prognostic value concerning PFS and cannot identify high risk patients for consolidation therapy. Imaging responders showed a significantly longer PFS compared to nonresponders and therefore PET/CT might serve as a prognostic biomarker.

A Review of Controversial Issues in the Management of Head and Neck Cancer: A Swiss Multidisciplinary and Multi-Institutional Patterns of Care Study-Part 1 (Head and Neck Surgery).

Background: The Head and Neck Cancer Working Group of Swiss Group for Clinical Cancer Research (SAKK) has investigated the level of consensus (LOC) and discrepancy in everyday practice of diagnosis and treatment in head and neck cancer. Materials and Methods: An online survey was iteratively generated with 10 Swiss university and teaching hospitals. LOC below 50% was defined as no agreement, while higher LOC were arbitrarily categorized as low (51-74%), moderate (75-84%), and high (≥85%). Results: Any LOC was achieved in 62% of topics (n = 60). High, moderate and low LOC were found in 18, 20, and 23%, respectively. Regarding Head and Neck Surgery, Radiation Oncology, Medical Oncology, and biomarkers, LOC was achieved in 50, 57, 83, and 43%, respectively. Conclusions: Consensus on clinical topics is rather low for surgeons and radiation oncologists. The questions discussed might highlight discrepancies, stimulate standardization of practice, and prioritize topics for future clinical research.

The expression of PD-L1 in salivary gland carcinomas.

Objective was to analyze the role of PD-L1 and its relation to demographic, patho-clinical and outcome parameters in salivary gland carcinoma (SGC) patients. Patients treated for salivary gland carcinomas between 1994 and 2010 were included. A retrospective chart review for baseline characteristics, pathohistological, clinical and outcome data was performed. Immunohistochemistry for PD-L1 was performed using tissue microarrays. PD-L1 expression was assessed in tumor cells and tumor-infiltrating immune cells (TIIC) and statistical analysis with regard to baseline and outcome data was performed. Expression of PD-L1 (by means ≥1% of the cells with PD-L1 positivity) was present in the salivary gland carcinoma cells of 17%, in the TIIC of 20% and in both tumor cells and TIIC of 10% the patients. PD-L1 expression in tumor cells and both tumor cells and TIIC was related to tumor grading (p = 0.035 and p = 0.031, respectively). A trend towards higher grading was also seen for PD-L1 expression in TIICs (p = 0.058). Patients with salivary duct carcinomas and PD-L1 expressing TIICs showed a significantly worse DFS and OS (p = 0.022 and p = 0.003, respectively), those with both tumor cells and TIIC expressing PD-L1 a significantly worse DFS (p = 0.030). PD-L1 expression is present in 17% and 20% of salivary gland carcinoma cells and TIIC. Ten percent of the patient showed a PD-L1 positivity in both tumor cells and TIIC. This is related to high tumor grading and therefore might be a negative prognostic factor.

Structured physical activity interventions as a complementary therapy for patients with inflammatory bowel disease - a scoping review and practical implications.

BACKGROUND: Patients with Inflammatory Bowel Disease (IBD) also suffer from a wide range of additional disorders, which may be caused by the disease, the side effect of the medication, or a lack of physical activity (PA). This results in reduced physical and psychological wellbeing. However, as known from other chronic diseases exercise could be utilized as supportive therapy for IBD patients. Main goals of this article are (a) collecting data of the effects structured physical activity interventions have on validated clinical parameters of IBD and health related symptoms, (b) developing activity recommendations for this clientele. METHODS: A scoping review was conducted, searching for relevant articles published until May 2018, which investigated the effects of structured exercise interventions in IBD patients. The heterogeneity of the outcomes and the interventions did not support a quantitative synthesis thus, a qualitative discussion of the studies is provided. RESULTS: After reviewing 353 records, 13 eligible articles were identified. Five studies investigated aerobic exercise, three studies resistance exercise, three studies mind-body therapies and two studies yoga. The quality of the studies is mixed, and the duration is rather short for exercise interventions. Only few studies assessed validated IBD activity markers or inflammatory biomarkers. Nevertheless, the patients showed an increase in fitness, bone mineral density (BMD), quality of life and a decrease of IBD induced stress and anxiety. No severe adversial events were reported. CONCLUSION: Even though the evidence is limited the application of exercise interventions in IBD patients can be assumed to be safe and beneficial for the patients' overall-health, and IBD specific physical and psychosocial symptoms. But there is still a high demand for more thoroughly conducted studies, focussing on important clinical outcome parameters.

Predictive Value of Pretherapeutic Maximum Standardized Uptake Value (Suvmax) In Laryngeal and Hypopharyngeal Cancer.

The aim of the study was to evaluate whether pretherapeutic metabolic tumor parameters from 18-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging could predict larynx preservation in laryngeal and hypopharyngeal cancer patients prior to primary chemoradiation. Tumor metabolic parameters [maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG)] were retrospectively assessed in a consecutive cohort of laryngeal and hypopharyngeal cancer patients undergoing primary (chemo-)radiation. Main outcome measures were larynx preservation and survival. The study included 97 patients with a median follow-up of 32 months (IQR 20-54.5). For hypopharyngeal cancer, multivariable analysis showed that patients with a primary tumor's SUVmax > 9.5 entailed a higher risk of undergoing salvage pharyngolaryngectomy after chemoradiation (HR = 8.64, 95% CI = 1.1-67.3, P = 0.040). In laryngeal cancer, SUVmax did not predict the need for salvage laryngectomy. The only predictor for larynx preservation in laryngeal cancer patients was T-classification at initial diagnosis (HR = 6.67, 95% CI = 0.82-53.9, P = 0.039). In conclusion, SUVmax of primary tumor could be used as a predictor of larynx preservation prior to primary chemoradiation in hypopharyngeal cancer patients. This information may be important for patient counseling, as high SUVmax was correlated with reduced probability of larynx preservation. However, in laryngeal cancer patients, SUVmax does not seem to be predictive of outcome.

First Clinicopathologic Evidence of a Non-PSMA-Related Uptake Mechanism for 68Ga-PSMA-11 in Salivary Glands.

The intense accumulation of prostate-specific membrane antigen (PSMA) radioligands in salivary glands is still not well understood. It is of concern for therapeutic applications of PSMA radioligands, because therapeutic radiation will damage these glands. A better understanding of the uptake mechanism is, therefore, crucial to find solutions to reduce toxicity. The aim of this study was to investigate whether the accumulation of PSMA-targeting radioligands in submandibular glands (SMGs) can be explained with PSMA expression levels using autoradiography (ARG) and immunohistochemistry (IHC). Methods: All patients gave written informed consent for further utility of the biologic material. The SMG of 9 patients, pancreatic tissue of 4 patients, and prostate cancer (PCA) lesions of 9 patients were analyzed. Tissue specimens were analyzed by means of PSMA-IHC (using an anti-PSMA-antibody and an immunoreactivity score system [IRS]) and ARG using 177Lu-PSMA-617 (with quantification of the relative signal intensity compared with a PSMA-positive standard). The SUVmax in salivary glands, pancreas, and PCA tissues were quantified in 60 clinical 68Ga-PSMA-11 PET scans for recurrent disease as well as the 9 primary tumors selected for ARG and IHC. Results: PCA tissue samples revealed a wide range of PSMA staining intensity on IHC (IRS = 70-300) as well as in ARG (1.3%-22% of standard). This variability on PCA tissue could also be observed in 68Ga-PSMA-11 PET (SUVmax, 4.4-16) with a significant correlation between ARG and SUVmax (P < 0.001, R2 = 0.897). On IHC, ARG, and 68Ga-PSMA-11 PET, the pancreatic tissue was negative (IRS = 0, ARG = 0.1% ± 0.05%, SUVmax of 3.1 ± 1.1). The SMG tissue displayed only focal expression of PSMA limited to the intercalated ducts on IHC (IRS = 10-15) and a minimal signal on ARG (1.3% ± 0.9%). In contrast, all SMG showed a high 68Ga-PSMA-11 accumulation on PET scans (SUVmax 23.5 ± 5.2). Conclusion: Our results indicate that the high accumulation of PSMA radioligands in salivary glands does not correspond to high PSMA expression levels determined using ARG and IHC. These findings provide evidence, that the significant accumulation of PSMA radioligands in SMG is not primarily a result of PSMA-mediated uptake.
