Stress perception, coping behaviors and work-privacy conflict of student midwives in times of COVID-19 pandemic: the "Healthy MidStudents" study in Germany.

BACKGROUND: Student midwives deliver care for women under challenging job demands, which may affect their mental health- thus creating a high need for health promotion. Given the lack of research addressing this topic, the aim of this study is to examine the links between stress perception, coping behaviors, work-privacy conflict, and perception of COVID-19 pandemic impact on studies of student midwives in northern Germany. METHODS: Data were collected using a cross-sectional online-survey at nine midwifery study sites in northern Germany from October 2022 to January 2023. 342 student midwives (response rate: 61.3%) were surveyed on stress perception, coping behaviors, work-privacy conflict, and perceived impact of the COVID-19 pandemic on their studies. Descriptive, linear regression and moderation analyses were run to test explorative assumptions. RESULTS: Results revealed that higher levels of perceived stress were reported by 13.4% of student midwives. Social support (M = 13.76, SD = 2.19) and active stress coping (M = 10.72, SD = 2.01) were identified as most prevalent coping behaviors in the present sample. It was found that work-privacy conflict was positively associated with stress perception (ß = 0.53, p =.001) and maladaptive coping behaviors (alcohol and cigarette consumption: ß = 0.14, p =.015), and negatively associated with adaptive coping behaviors (positive thinking: ß = - 0.25, p =.001, social support: ß = - 0.23, p =.001). Students with children reported significantly lower levels of social support than students without children. 55.6% of student midwives perceived a negative impact of the COVID-19 pandemic on their studies (mostly on lectures, seminars, and contact with fellow students). CONCLUSIONS: Key findings highlighted moderate stress levels among student midwives during theoretical study stage. Based on current research, prevalence of high stress levels among student midwives remains unclear. Given the overall heterogeneous, limited research on student midwives' stress perception, coping behaviors, work-privacy conflict and perceptions of COVID-19 pandemic impact on studies, implications for research are suggested, e.g. longitudinal studies at different time points and settings and interventional studies. Findings provide a starting point for implementation of workplace health promotion in theoretical and practical stages of midwifery science study programs, e.g. training courses on stress prevention and adaptive coping, and for improvement of working conditions.

Spatial characteristics of non-communicable diseases and their associations to social conditions in a large urban cohort in Germany-Results from the Hamburg City Health Study.

BACKGROUND: Non-communicable diseases (NCDs) are responsible for many deaths. They are associated with several modifiable and metabolic risk factors and are therefore prone to significant regional variations on different scales. However, only few intra-urban studies examined spatial variation in NCDs and its association with social circumstances, especially in Germany. Thus, the present study aimed to identify associations of personal risk factors and local social conditions with NCDs in a large German city. METHODS: This study is based on a population-based cohort of the Hamburg City Health Study including 10,000 probands. Six NCDs were analyzed (chronic obstructive pulmonary disease [COPD], coronary heart disease [CHD], diabetes mellitus, heart failure, depression, and hypertension) in 68 city district clusters. As risk factors, we considered socio-demographic variables (age, sex, education) and risk behaviour variables (smoking, alcohol consumption). Logistic regression analyses identified associations between the district clusters and the prevalence rates for each NCD. Regional variation was detected by Gini coefficients and spatial cluster analyses. Local social condition indexes were correlated with prevalence rates of NCDs on city district level and hot-spot analyses were performed for significant high or low values. RESULTS: The analyses included 7,308 participants with a mean age of 63.1 years (51.5% female). The prevalence of hypertension (67.6%) was the highest. Risk factor associations were identified between smoking, alcohol consumption and education and the prevalence of NCDs (hypertension, diabetes, and COPD). Significant regional variations were detected and persisted after adjusting for personal risk factors. Correlations for prevalence rates with the local social conditions were significant for hypertension (r = 0.294, p < 0.02), diabetes (r = 0.259, p = 0.03), and COPD (r = 0.360, p < 0.01). CONCLUSIONS: The study shows that regional differences in NCD prevalence persist even after adjusting for personal risk factors. This highlights the central role of both personal socio-economic status and behaviors such as alcohol and tobacco consumption. It also highlights the importance of other potential regional factors (e.g. the environment) in shaping NCD prevalence. This knowledge helps policy- and decision-makers to develop intervention strategies.

[Role of nutrition in urological prehabilitation]. / Rolle der Ernährung in der urologischen Prähabilitation.

Nutritional intervention plays an important role in prehabilitation, a multimodal concept designed to improve the physical condition of the patient prior to treatment in order to influence the outcome of surgery. The focus is on reducing the postoperative complication rate, while simultaneously shortening the hospital stay and the rehabilitation phase. The nutritional status should be optimized through individual counseling and the targeted intake of calories, protein, and nutritional supplements. A good nutritional status contributes to the strengthening of the immune system and improves wound healing. Especially after surgery, muscle mass declines rapidly. Adequate protein intake accompanying strength exercises can best preserve muscle and promote development of muscular fitness during prehabilitation. Despite the positive effects of nutritional interventions, prehabilitation programs with nutritional components in uro-oncology are rare and the evidence of the programs is therefore insufficient. Results from initial studies appear promising, but further prospective, randomized studies of high quality and with defined program content on the various types of cancer are needed.

Association between an Anti-Inflammatory Dietary Score and Periodontitis-Evidence from the Population-Based Hamburg City Health Study.

While the effects of dietary patterns on cardiovascular risk and diabetes have been well studied, the evidence is scarce as to which diet has the greatest anti-inflammatory potential and how dietary patterns are associated with periodontitis. In the Hamburg City Health Study (HCHS), we developed an anti-inflammatory dietary score using a data-driven approach based on the relationship of relevant selected food groups with inflammatory biomarkers (hsCRP and IL-6). The aim of this cross-sectional study was to evaluate the association between the anti-inflammatory dietary score and the incidence of periodontitis in Hamburg, Germany. A total of n = 5642 participants fit the required inclusion criteria and were selected for analysis. Periodontal disease was assessed using probing depth, gingival recession, and bleeding on probing. Dietary intake was measured using a food frequency questionnaire (FFQ). A self-developed anti-inflammatory dietary score served as the key explanatory variable. Higher scores reflected lower inflammatory processes (measured through the biomarkers hsCRP and IL-6). Several covariates were included in the regression analysis. Regressions revealed that a higher anti-inflammatory dietary score was significantly associated with lower odds to be affected by periodontal disease in an unadjusted model (OR 0.86, 95% CI 0.82-0.89, p < 0.001) and in an adjusted model (age, sex, smoking, diabetes, hypertension, and physical activity) (OR 0.93, 95% CI 0.89-0.98, p = 0.003). Our study demonstrated a significant inverse association between an anti-inflammatory dietary score and periodontitis. Individuals with higher intake of proinflammatory nutrition should be specifically addressed to avoid periodontitis.

Feasibility, acceptability, and behavioral outcomes of a multimodal intervention for prostate cancer patients: Experience from the MARTINI lifestyle program.

BACKGROUND: Prostate cancer (PCa) is the most frequently diagnosed malignant tumor in men. The potential benefit of a healthy lifestyle contrasts sharply with the observed poor adherence to current international lifestyle guidelines. Thus, well-designed sustainable interventions of aftercare that can be translated into routine practice are highly recommended. The present pilot study aimed to evaluate the feasibility and acceptability of a multimodal lifestyle intervention program in PCa patients after radical prostatectomy (RP). METHODS: In a single-arm study, carried out at the Martini-Klinik of the University Medical Center Hamburg-Eppendorf, Germany, 59 eligible men with locally advanced PCa were recruited within 3-6 months after RP and assigned to a multimodal lifestyle program. The program consisted of 10 weekly 6-7 h course days, with a focus on dietary control, physical activity (per World Cancer Research Fund recommendations) and psychological support. Primary objectives were feasibility, acceptability, completion rate, and safety. In addition, changes in lifestyle, psychological well-being, clinical and laboratory values were assessed. The study was registered in the German Clinical Trials Register (No. DRK S00015288 [MARTINI-Lifestyle-cohort] [www.germanctr.de]). RESULTS: A high program acceptance was observed. Only three participants (5%) dropped out of the program prematurely. Personal feedback reflected appreciation for participation, personal gain through new knowledge and through the group experience. Without exception, all participants have taken part in follow-up examinations and no adverse events or incidents occurred. In addition, changes in lifestyle habits, clinical parameters and improved quality of life were detected. CONCLUSION: The MARTINI lifestyle program appears feasible and safe, and acceptance of the multimodal intervention was high among PCa patients. These encouraging results favor conducting a large multicenter trial to implement the program into routine practice and to evaluate the effectiveness of the intervention on survival and quality of life.

Coffee consumption and associations with blood pressure, LDL-cholesterol and echocardiographic measures in the general population.

Coffee, next to water the most widespread beverage, is attributed both harmful and protective characteristics concerning cardiovascular health. This study aimed to evaluate associations of coffee consumption with cardiac biomarkers, echocardiographic, electrocardiographic parameters and major cardiovascular diseases. We performed a cross-sectional analysis of 9009 participants of the population-based Hamburg City Health Study (HCHS), enrolled between 2016 and 2018 median age 63 [IQR: 55; 69] years. Coffee consumption was classified into three groups: < 3 cups/day (low), 3-4 cups/day (moderate), > 4 cups/day (high). In linear regression analyses adjusted for age, sex, body mass index, diabetes, hypertension, smoking, and additives, high coffee consumption correlated with higher LDL-cholesterol (ß = 5.92; 95% CI 2.95, 8.89; p < 0.001). Moderate and high coffee consumption correlated with lower systolic (ß = - 1.91; 95% CI - 3.04, - 0.78; p = 0.001; high: ß = - 3.06; 95% CI - 4.69, - 1.44; p < 0.001) and diastolic blood pressure (ß = - 1.05; 95% CI - 1.67, - 0.43; p = 0.001; high: ß = - 1.85; 95% CI - 2.74, - 0.96; p < 0.001). Different levels of coffee consumption did neither correlate with any investigated electrocardiographic or echocardiographic parameter nor with prevalent major cardiovascular diseases, including prior myocardial infarction and heart failure. In this cross-sectional analysis, high coffee consumption correlated with raised LDL-cholesterol levels and lower systolic and diastolic blood pressure. However, major cardiovascular diseases including heart failure and its diagnostic precursors were not associated with coffee consumption, connoting a neutral role of coffee in the context of cardiovascular health.

Cross-Sectional Association of Dietary Patterns and Supplement Intake with Presence and Gray-Scale Median of Carotid Plaques-A Comparison between Women and Men in the Population-Based Hamburg City Health Study.

This population-based cross-sectional cohort study investigated the association of the Mediterranean and DASH (Dietary Approach to Stop Hypertension) diet as well as supplement intake with gray-scale median (GSM) and the presence of carotid plaques comparing women and men. Low GSM is associated with plaque vulnerability. Ten thousand participants of the Hamburg City Health Study aged 45-74 underwent carotid ultrasound examination. We analyzed plaque presence in all participants plus GSM in those having plaques (n = 2163). Dietary patterns and supplement intake were assessed via a food frequency questionnaire. Multiple linear and logistic regression models were used to assess associations between dietary patterns, supplement intake and GSM plus plaque presence. Linear regressions showed an association between higher GSM and folate intake only in men (+9.12, 95% CI (1.37, 16.86), p = 0.021). High compared to intermediate adherence to the DASH diet was associated with higher odds for carotid plaques (OR = 1.18, 95% CI (1.02, 1.36), p = 0.027, adjusted). Odds for plaque presence were higher for men, older age, low education, hypertension, hyperlipidemia and smoking. In this study, the intake of most supplements, as well as DASH or Mediterranean diet, was not significantly associated with GSM for women or men. Future research is needed to clarify the influence, especially of the folate intake and DASH diet, on the presence and vulnerability of plaques.

Editor's Choice - Prevalence of Peripheral Arterial Disease, Abdominal Aortic Aneurysm, and Risk Factors in the Hamburg City Health Study: A Cross Sectional Analysis.

OBJECTIVE: There is a paucity of current figures on the prevalence of carotid and lower extremity peripheral arterial disease (PAD) and abdominal aortic aneurysm (AAA) as well as the associated cardiovascular risk factors to support considerations on screening programmes. METHODS: In the population based Hamburg City Health Study, participants between 45 and 74 years were randomly recruited. In the current cross sectional analysis of the first 10 000 participants enrolled between February 2016 and November 2018, the prevalence of carotid artery disease (intima-media thickness ≥ 1 mm), lower extremity PAD (ankle brachial index ≤ 0.9), and AAA (aortic diameter ≥ 30 mm) was determined. Multivariable logistic regression models were applied to determine the association between vascular diseases and risk factors. To account for missing values, multiple imputation was performed. RESULTS: A total of 10 000 participants were analysed (51.1% females, median age 63 years, median body mass index 26.1 kg/m2). In medians, the intima media thickness was 0.74 mm (interquartile range [IQR] 0.65 - 0.84), the ankle brachial index 1.04 (IQR 0.95 - 1.13), and the aortic diameter 17.8 mm (IQR 16.1 - 19.6). Concerning risk factors, 64% self reported any smoking, 39% hypertension, 5% coronary artery disease, 3% congestive heart failure, 5% atrial fibrillation, and 3% history of stroke or myocardial infarction, respectively. In males, the prevalence of carotid artery disease, lower extremity PAD, and AAA were 35.3%, 22.7%, and 1.3%, respectively, and in females, 23.4%, 24.8%, and 0.2%, respectively. Higher age and current smoking were likewise associated with higher prevalence while the impact of variables varied widely. CONCLUSION: In this large population based cohort study of 10 000 subjects from Hamburg, Germany, a strikingly high prevalence of PAD was revealed. Almost 45% suffered from any index disease, while AAA was only diagnosed in 1.3% of males and 0.2% of females. The high prevalence of atherosclerotic disease and associated cardiovascular risk factors underline that it is essential to increase awareness and fuel efforts for secondary prevention.

Lifestyle changes to prevent cardio- and cerebrovascular disease at midlife: A systematic review.

Cardio- and cerebrovascular diseases are leading causes of death and morbidity in ageing populations. While numerous cohort studies show inverse associations of presumably healthy lifestyles and cardiovascular risk factors, the causal link to many modifiable behaviors is still insufficiently evidence-based. Because of bias of studies and heterogeneity of results, we performed a systematic review of meta-analyses of randomized controlled trials and observational studies on lifestyle patterns including nutrition, physical activity, smoking, and weight versus incidence and mortality of cardio- and cerebrovascular diseases. A search string retrieved 624 references in PubMed covering the last five years. Two researchers screened titles and abstracts independently but with equivalent results. Nineteen references met the inclusion criteria. Results affirm that high adherence to plant-based diets, including components such as fruits, vegetables, legumes, whole grains, low-fat dairy, olive oil, nuts, and low intake of sodium, sweetened beverages, alcohol, and red and processed meats, results in lower risk of vascular outcomes in a dose-dependent manner. Physical activity quantified as walking pace or cardiorespiratory fitness yielded an inverse effect on stroke. Health measures such as smoking status, BMI and increase in body weight are associated with substantial risk of the incidence of and mortality from cardio- and cerebrovascular diseases, while strong adherence to an overall prudent lifestyle lowered the risk of cardiovascular disease by 66 % and that stroke by 60 %. In summary, increasing numbers of and adherence to health behaviors may markedly lower the burden of cardio- and cerebrovascular diseases. However, future research should focus on randomized controlled trials to test for causal relationships.

Behavioral Health Risk Factors and Motivation to Change among Cardiovascular General Hospital Patients Aged 50 to 79 Years.

Little is known about the (co-)occurrence of smoking, alcohol at-risk drinking, physical inactivity and overweight, and the motivation to change these behavioral health risk factors (HRFs) in older general hospital patients with cardiovascular disease. Between October and December 2016, all consecutively admitted patients aged 50 to 79 years were proactively recruited on 3 cardiology wards and asked to participate in a survey on HRFs and behavior change motivation. Of the eligible patients, 80.4% participated in the survey (n = 328). The mean age was 66.5 years (standard deviation 9.0), and 65.5% were male. At least 1 HRF was present in 91.8% (n = 280), at least 2 HRFs in 54.4% (n = 166), and 3 or 4 HRFs in 12.1% (n = 37) of participants. The proportion of older adults who contemplated or were changing or planning to change their behavior to meet health behavior recommendations ranged between 66.0% (smoking) and 93.2% (alcohol consumption). The results indicate a notable co-occurrence of behavioral HRFs in older patients with cardiovascular disease. The majority of older adults were at least considering changing the respective behavior. To prevent and treat diseases efficiently, hospitalization may be a suitable moment for systematic multiple HRF screening and intervention.

Randomised controlled trial testing the feasibility of an exercise and nutrition intervention for patients with ovarian cancer during and after first-line chemotherapy (BENITA-study).

OBJECTIVES: Advanced ovarian cancer is a severe disease with major side effects caused by peritoneal carcinomatosis, ascites and gastrointestinal involvement as well as exhaustive treatment like debulking surgery and combination chemotherapy. Two most frequently reported side effects are muscle wasting and malnutrition, leading to frailty, decreased health-related quality of life (HRQoL) and cancer-related fatigue (CRF). As muscle wasting and malnutrition often commence during first-line chemotherapy and develop progressively into a refractory state, an early intervention is warranted. This pilot study aimed to evaluate the safety and acceptance of a combined exercise and nutrition intervention during and after first-line chemotherapy. DESIGN: The pilot study was conducted as a monocentric 1:1 randomised controlled trial (RCT) with an intervention group (IG) and a control group (CG). Participants were divided by chance into IG or CG. Information on group allocation was conveyed to the study coordinator responsible for making an appointment with the patients for the baseline assessment as well as the physiotherapist and nutritionist responsible for the intervention and outcome assessment in both groups. PARTICIPANTS: Eligibility criteria included women ≥18 years of age, diagnosed with ovarian cancer, tubal cancer or peritoneal cancer and primary or interval debulking, scheduled but not started adjuvant or neoadjuvant chemotherapy and sufficient German-language skills. INTERVENTION: The IG received a 12-month exercise and nutrition programme, the CG continued to follow usual care. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes were recruitment rate, adherence to intervention, completion rate and adverse events. In addition, in-person assessments (eg, HRQoL, CRF, muscle quality and function and dietary intake and quality) were conducted at baseline (T0, before chemotherapy), week 9 (T1, mid-chemotherapy), week 19 (T2, after completion of chemotherapy) and after 12 months of intervention (T3). RESULTS: Of 60 eligible patients, 15 patients signed informed consent (recruitment rate=25.0%) and were randomised into IG (n=8) and CG (n=7). Eleven participants completed the study (completion rate, 73.3%), one patient dropped out due to loss of interest, one due to poor health, one was lost to follow-up and one patient died. CONCLUSION: The BENITA (Bewegungs- und Ernährungsintervention bei Ovarialkrebs) study demonstrated the safety and acceptance of an exercise and nutrition intervention integrated into first-line therapy and follow-up care of ovarian cancer. A large multicentre RCT is planned to investigate the effectiveness of the intervention on HRQoL, CRF and survival and to establish means of implementation into oncology guidelines and clinic routine. TRIAL REGISTRATION NUMBER: DRKS00013231.

Association between periodontitis and metabolic syndrome in the Hamburg City Health Study.

BACKGROUND: Previous studies demonstrated an association between severe chronic periodontitis (CP) and metabolic syndrome (MetS). However, these studies mostly used the outdated National Cholesterol Education Program-Adult Treatment Panel (NCEP-ATP) III case definition of MetS. Additionally, CP was rarely diagnosed based on a full-mouth examination. Thus, the aim of the current study was to re-evaluate the potential association between CP and MetS in the Hamburg City Health Study (HCHS), a large population-based survey of middle-aged and elderly men and women in Germany, in view of more current definitions of MetS and CP. METHODS: A cross-sectional study was performed with baseline-data from participants of the HCHS. Periodontitis severity grades were determined in a random sample of 6,209 participants of which 5,456 had sufficient data to call absence or presence of MetS. Variables defining MetS according to the currently valid harmonized definition were determined and a full-mouth examination was performed, including determination of the clinical attachment loss, bleeding on probing, and dental plaque index. CP was classified in three grades of severity (none/mild, moderate, and severe). The Kruskal-Wallis test or the Chi-squared test were used for descriptive statistics and multivariate logistic regression models with and without adjustments for potential confounders (age, sex, smoking, high-sensitivity C-reactive protein [hsCRP], energy intake, and physical activity) were used to test for associations. RESULTS: The prevalence of MetS (39.0%) increased according to the severity grades of periodontitis (none/mild: 33.6%; moderate: 38.7%, and severe: 46.8%). Multivariate logistic regression analyses demonstrated that severe but not moderate CP was associated with MetS after adjusting for age and sex (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.03 to 1.48; P = 0.02). However, the association was attenuated after additional adjustment for smoking (OR, 1.19; 95% CI, 0.99 to 1.43; P = 0.058) and hsCRP, energy intake, and physical activity (OR, 1.11; 95% CI, 0.91 to 1.36; P = 0.294). CONCLUSIONS: The use of the more current definitions for MetS and CP confirmed previous observations of an age- and sex-adjusted association between severe CP and MetS. Smoking, high-energy intake, and low physical activity were identified as important lifestyle-related confounders. Abdominal obesity, as indicated by elevated waist circumference, was determined as the most important component of MetS in relationship to CP.

The Health Behaviour of German Outpatient Caregivers in Relation to Their Working Conditions: A Qualitative Study.

Ongoing demographic change is leading to an increasingly older society and a rising proportion of people in need of care in the German population. Therefore, the professional group of outpatient caregivers is highly relevant. Their work is characterised not only by interacting with patients in a mobile setting but also by working in shifts. Health behaviour under these specific working conditions is crucial for ensuring long-term work ability and performance. Little is known about the health behaviour of German outpatient caregivers and its potential impact on their work. The aims of the study were (1) to examine health behavioural patterns (nutrition, exercise, smoking, regeneration) of outpatient caregivers, (2) to illuminate their personal health-promoting behaviours, and (3) to identify potential work-related factors influencing their health behaviour. Fifteen problem-centred interviews were conducted with outpatient caregivers working in Northern Germany in the period January-April 2020. Interviews were analysed by using qualitative content analysis. Outpatient caregivers reported improvable nutrition and hydration, with simultaneous high coffee consumption, low physical activity, poor regeneration (breaks and sleep quality), and good personal health-promoting behaviour (e.g., back-friendly habits), although the majority were smokers. Barriers to the implementation of health-promoting behaviours were a high perception of stress due to increased workload and time pressure, while aids to better health-promoting behaviour were described as being social support and personal resources. The respondents perceived their working conditions as potentially influencing their health behaviour. On the basis of their descriptions, various practice-relevant strategies were derived. The data explore a potential need for outpatient care services to develop interventions on behavioural and structural levels that can help create healthier working conditions for their employees so these caregivers can adopt better health behaviours.

Circulating Vitamin D and Selenium Levels and Outcome in Prostate Cancer Patients: Lessons from the MARTINI-Lifestyle Cohort.

BACKGROUND: Dietary agents, in particular vitamin D (Vit D) and selenium, are widely used by prostate cancer (PCa) patients to improve cancer outcomes. OBJECTIVE: To investigate whether plasma Vit D and selenium levels prior to radical prostatectomy (RP) are associated with worse pathologic tumor characteristics and increased risk of disease recurrence. DESIGN, SETTING, AND PARTICIPANTS: A total of 3849 men with PCa scheduled for RP in the Martini-Klinik at the University Hospital Hamburg-Eppendorf, Hamburg, Germany, between January 2014 and December 2018 were included in this study. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Age, and clinical and laboratory values were collected prior to RP. Biochemical recurrence (BCR) was defined as prostate-specific antigen (PSA) ≥0.2 µg/l and rising after RP. Kaplan-Meier plots depicted BCR-free survival. Cox regression models (adjusted for age, preoperative PSA, pT stage, pN stage, pGG, surgical margin status, and year of surgery) tested the relationship between oncologic outcomes and Vit D and selenium levels. RESULTS AND LIMITATIONS: Median plasma Vit D and selenium levels were 19.3 and 71 µg/l, respectively. Circulating Vit D and selenium levels correlated inversely with PSA values. Histologic grade, pT stage, and pN stage were not associated with Vit D and selenium levels at the time of RP. In the overall cohort, BCR-free survival at 3 yr of follow-up was 82.9%. When stratified according to median Vit D levels, BCR-free survival at 3 yr of follow-up was 82.7% and 83.0% (p ≤ 0.59). Upon stratification according to median selenium levels, BCR-free survival was 82.2% and 83.7% (p = 0.19). In a multivariable Cox regression model predicting BCR, lower Vit D and selenium levels were not independent predictors of BCR. CONCLUSIONS: Plasma Vit D and selenium levels prior to RP were not associated with BCR-free survival. PATIENT SUMMARY: The results of the MARTINI-Lifestyle cohort could not show a correlation between the occurrence of biochemical recurrence of prostate cancer after radical prostatectomy and the serum levels of vitamin D and selenium. A recommendation should therefore be made to compensate for a potential deficiency and not with the expectation of a reduction in the risk of progression.

An exercise and nutrition intervention for ovarian cancer patients during and after first-line chemotherapy (BENITA study): a randomized controlled pilot trial.

BACKGROUND: Data on the treatment-supporting effect of modifiable lifestyle factors such as nutrition and physical activity on survival or quality of life (QoL) are scarce in patients with ovarian cancer. Despite a strong rationale for evaluating the effect of a multimodal intervention and multiple studies targeting other cancer sites, randomized controlled trials (RCTs) on the effects of a combined nutrition and exercise intervention on survival and QoL in ovarian cancer patients are rare. No study has investigated the impact of an early intervention during first-line chemotherapy. PRIMARY OBJECTIVES: To evaluate the study design, feasibility, safety, and acceptance of combined nutrition and exercise in patients diagnosed with ovarian cancer during and after first-line chemotherapy. STUDY HYPOTHESIS: Physical exercise and a cancer-specific nutrition intervention after ovarian cancer diagnosis is feasible, accepted, and safe for patients receiving first-line chemotherapy. TRIAL DESIGN: A 1:1 RCT with an intervention group and a control group. The intervention group receives an exercise and nutrition program whereas the control group continues to follow the usual care. MAJOR INCLUSION/EXCLUSION CRITERIA: Inclusion: women ≥18 years of age; women diagnosed with ovarian cancer, tubal cancer, or peritoneal cancer and primary or interval debulking surgery. Exclusion: Eastern Cooperative Oncology Group (ECOG) status of 2 or worse. PRIMARY ENDPOINTS: Recruitment rate, completion rate, side effects, and adherence. SAMPLE SIZE: n=30 patients (15 per arm) will be recruited. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Accrual completion is planned for the end of 2019. Results will be presented in the months following study completion 1 year after recruitment has been finalised. TRIAL REGISTRATION NUMBER: The pilot phase was approved by the ethics committee of the Medical Faculty of Hamburg on December 13, 2017 (PV5456). The study was registered on September 9, 2018 at the German Study Registry for Clinical Studies (DRKS00013231).

Poor Adherence to International Cancer Prevention Recommendations Among Patients With Prostate Cancer: First Results From the MARTINI-Lifestyle Cohort.

BACKGROUND: Promotion of a healthy lifestyle in patients with prostate cancer (PCa) has gained traction to increase patient investment in his/her health care practices, improve patient quality of life, and improve survival outcomes. OBJECTIVE: To investigate adherence of patients with PCa to healthy lifestyle recommendations from the World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR). DESIGN, SETTING, AND PARTICIPANTS: A total of 2227 men with PCa scheduled for radical prostatectomy in the Martini-Klinik at the University Hospital Hamburg-Eppendorf, Hamburg, Germany between January 2016 and December 2017. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Age and clinical characteristics were collected at the time of the diagnosis. Assessment of diet and physical activity data were obtained via e-mail surveys using validated questionnaires developed for the European Prospective Investigation into Cancer and Nutrition (EPIC) study [food frequency questionnaire, version 2 (FFQ2), EPIC-Physical Activity Questionnaire (EPIC-PAQ)]. Baseline characteristics were calculated as means and standard deviations for continuous data or counts and percentages for categorical data. RESULTS AND LIMITATIONS: Patients followed 3.3 (±1.5) of the 10 WCRF/AICR recommendations. None of the participants reached all goals; 67.3% of the patients did not fulfill the criteria of a healthy normal weight, 33.5% reported no exercise at all, and 49.6% were characterized as current or ex-smokers. As to nutritional goals, 75.4% did not meet the recommended intake of meat, 88.8% reported a low consumption of fruit and vegetables, and 86% did not achieve the recommended fiber intake. Because these analyses are based on self-reported data of diet and lifestyle, a bias toward underreporting cannot be excluded. CONCLUSIONS: First results of the MARTINI-Lifestyle cohort show that adherence to the AICR/WCRF recommendations for cancer prevention is poor. PATIENT SUMMARY: Patients with prostate cancer scheduled for surgery do not adhere to cancer prevention guidelines. Thus, improving lifestyle habits may provide significant impact on patient health and quality of life.

Adherence to Mediterranean diet, high-sensitive C-reactive protein, and severity of coronary artery disease: Contemporary data from the INTERCATH cohort.

BACKGROUND AND AIMS: Guidelines recommend a healthy diet as a cornerstone of cardiovascular disease (CVD) prevention. Although the Mediterranean diet (MD) is the best studied dietary pattern for CV outcomes, data on association between MD and severity of CAD are limited. Therefore, we analysed dietary data in association with the SYNTAX score in coronary artery disease (CAD) patients from the INTERCATH study. METHODS: The INTERCATH study is an observational study in patients undergoing coronary angiography at the University Heart Center Hamburg. Coronary morphology is assessed by the SYNTAX score. A lifestyle questionnaire collects dietary data with food frequency questions at baseline. Based on seven dietary characteristics, we calculated an established Mediterranean diet score (MDS) with a range of 0-28 points at which 28 points reflect maximal adherence to MD. To investigate the association of MD with severity of CAD, we performed logistic regression analysis after adjustment for confounding factors. RESULTS: Of 1121 patients, 27% were women. The median age was 70.7 years (interquartile range (IQR) 61.1,77.0). CV risk factors were distributed as expected for a CAD cohort (31.3% diabetes, 81.1% arterial hypertension, 34.0% smoking, median BMI 26.6 kg/m2 (IQR 24.1, 30.3), median LDL-C 87 mg/dL (IQR 65.0,116,6). Of all variables included, the strongest correlation with MDS was found for log (hs-CRP) (r = -0.21, p < 0.001). Adherence to MD represented by a higher MDS was significantly associated with a reduced probability for a medium/high risk SYNTAX score of ≥23 with an odds ratio (OR) of 0.923 per point increase of MDS (95% confidence interval 0.869-0.979; p = 0.0079). This association remained significant after adjustment for cardiovascular risk factors (OR 0.934, 95% CI 0.877-0.995, p = 0.035). After further adjustment for log (hs-CRP), the association remained no longer significant (OR 0.955 (0.893-1.022, p = 0.19). CONCLUSIONS: In this contemporary data set, we found an independent association of adherence to MD with a less complex CAD. Hs-CRP correlated significantly with adherence to MD and may be a marker of the vasoprotective effects of MD. These results strengthen the evidence for the protective effect of an MD pattern in CVD prevention.

Joint Data Analysis in Nutritional Epidemiology: Identification of Observational Studies and Minimal Requirements.

Background: Joint data analysis from multiple nutrition studies may improve the ability to answer complex questions regarding the role of nutritional status and diet in health and disease. Objective: The objective was to identify nutritional observational studies from partners participating in the European Nutritional Phenotype Assessment and Data Sharing Initiative (ENPADASI) Consortium, as well as minimal requirements for joint data analysis. Methods: A predefined template containing information on study design, exposure measurements (dietary intake, alcohol and tobacco consumption, physical activity, sedentary behavior, anthropometric measures, and sociodemographic and health status), main health-related outcomes, and laboratory measurements (traditional and omics biomarkers) was developed and circulated to those European research groups participating in the ENPADASI under the strategic research area of "diet-related chronic diseases." Information about raw data disposition and metadata sharing was requested. A set of minimal requirements was abstracted from the gathered information. Results: Studies (12 cohort, 12 cross-sectional, and 2 case-control) were identified. Two studies recruited children only and the rest recruited adults. All studies included dietary intake data. Twenty studies collected blood samples. Data on traditional biomarkers were available for 20 studies, of which 17 measured lipoproteins, glucose, and insulin and 13 measured inflammatory biomarkers. Metabolomics, proteomics, and genomics or transcriptomics data were available in 5, 3, and 12 studies, respectively. Although the study authors were willing to share metadata, most refused, were hesitant, or had legal or ethical issues related to sharing raw data. Forty-one descriptors of minimal requirements for the study data were identified to facilitate data integration. Conclusions: Combining study data sets will enable sufficiently powered, refined investigations to increase the knowledge and understanding of the relation between food, nutrition, and human health. Furthermore, the minimal requirements for study data may encourage more efficient secondary usage of existing data and provide sufficient information for researchers to draft future multicenter research proposals in nutrition.

Interaction of smoking and dietary habits modifying the risk of coronary heart disease in women: results from a case-control study.

BACKGROUND/OBJECTIVES: Smoking is a strong risk factor for coronary heart disease particularly in women. The risk may be aggravated by dietary habits, though. SUBJECTS/METHODS: The Coronary Risk for Atherosclerosis Study (CORA) compares dietary, lifestyle, biochemical, and clinical factors in 200 consecutive pre- and postmenopausal women with incident coronary heart disease to those of 255 age-matched population-based controls. A mixed logistic regression model was used to assess the possible interactions between smoking habits and dietary patterns. RESULTS: Each increase of 100 kcal energy intake per day was positively associated with coronary risk (OR 1.10, 95% CI 1.03-1.17; p = 0.006). Doubling the intake of alcohol and vegetables was negatively related with coronary risk (alcohol: OR 0.61, 95% CI 0.50-0.73; p < 0.001; vegetables: OR 0.50, 95% CI 0.032-0.080; p = 0.003). In contrast, doubling the intake of meat was associated with an increase of coronary risk, but only in smoking women (OR 2.61, 95%CI 1.58-4.29; p < 0.001). In smoking women a high meat-over-vegetable-ratio indicated an even higher risk (ratio of 2.0: OR 5.77, 95% CI 2.13-15.67; p < 0.001), while a low meat-over-vegetable-ratio did not have a significant impact on coronary risk (ratio of 0.5: OR 1.28, 95% CI 0,78-2.09). CONCLUSIONS: This explorative analysis of the CORA-study indicates that a high intake of meat is significantly associated with an increase in coronary risk particularly in smoking women, and may account for part of the unadjusted risk of smoking.

Depressive symptoms and metabolic risk: effects of cortisol and gender.

We examined gender effects and the role of cortisol in the association between depressive symptoms and metabolic risk in the Stress, Atherosclerosis, and ECG Study (STRATEGY). In 215 healthy adults from the general population (n=107 men, n=108 women, distributed equally across four age groups, 30-70 years), we assessed depressive symptoms by the Patient Health Questionnaire (PHQ score >10) and measured variables of the metabolic syndrome: high-density lipoprotein (HDL), triglycerides, systolic and diastolic blood pressure, fasting blood glucose and waist circumference. Salivary cortisol was assessed at 08:00, 12:00, 16:00 and 22:00 h. Depressive symptoms were not associated with the metabolic syndrome as entity in the total sample or in men and women separately. However, women with depressive symptoms had larger waist circumferences, higher fasting blood glucose, lower HDL-cholesterol, higher diastolic blood pressure, and higher 16:00 and 22:00 h salivary cortisol compared to women without depressive symptoms. These results persisted after adjusting for age, education, smoking, and physical activity. In adjusted regression analyses, inclusion of cortisol attenuated the association between depressive symptoms and waist, fasting glucose, HDL and diastolic blood pressure in women. In men, we did not find an association between depressive symptoms and variables of the metabolic syndrome. In women, depressive symptoms are associated with several variables of the metabolic syndrome. Elevated afternoon and evening cortisol appear to partially mediate this association.
