Objective: The aim of the study was to assess the association of hypertension and symptoms of depression and generalized anxiety in a large cohort of elderly people. Methods: Data were derived from the 8-year follow-up (2008–2010) of the epidemiological ESTHER-cohort study. A total of 3124 randomly chosen participants aged 57–84 were visited at their homes by trained study doctors. General practitioner based diagnosis, self-reported status of hypertension, medication, and blood pressure measurement were considered to define the existence of hypertension. Depression and general anxiety severity were assessed using validated questionnaires. Logistic regression analyses were performed to determine cross-sectional associations between hypertension and clinically significant symptoms of depression (CSD) and generalized anxiety. Well known lifestyle risk factors for hypertension such as obesity were included in multivariate cross-sectional analyses. Results: Hypertension was prevalent in 1659 participants [53.1%; 95% confidence interval (CI) = (51.3; 54.9)]. CSD was detected in 163 participants [5.2%; 95%-CI = (4.4; 6.0)]. Symptoms of generalized anxiety were found in 434 participants [13.9%; 95%-CI = (12.7; 15.1)]. Patients with CSD showed significantly higher odds of being hypertensive [odds ratio (OR) = 1.76; 95%-CI = (1.14; 2.74)]. Participants with symptoms of generalized anxiety were found to have no higher odds for a hypertension diagnosis [OR = 1.1; 95%-CI = (0.85; 1.44)]. Overweight [OR = 1.86; 95%-CI = (1.53; 2.25)] as well as obesity [OR = 3.58; 95%-CI = (2.84; 4.52)] was significantly associated with hypertension. Conclusion: CSD appear to be related to hypertension in elderly adults. No association was found between symptoms of generalized anxiety and hypertension.

Cancer-related fatigue (CRF) is a burdensome sequela of cancer treatments. Besides exercise, recommended therapies for CRF include yoga, psychosocial, and mindfulness-based interventions. However, interventions conducted vary widely, and not all show a significant effect. This meta-analysis aimed to explore intervention characteristics related to greater reductions in CRF. We included randomized controlled trials published before October 2021. Standardized mean differences were used to assess intervention efficacy for CRF and multimodel inference to explore intervention characteristics associated with higher efficacy. For the meta-analysis, we included 70 interventions (24 yoga interventions, 31 psychosocial interventions, and 15 mindfulness-based interventions) with 6387 participants. The results showed a significant effect of yoga, psychosocial, and mindfulness-based interventions on CRF but with high heterogeneity between studies. For yoga and mindfulness-based interventions, no particular intervention characteristic was identified to be advantageous for reducing CRF. Regarding psychosocial interventions, a group setting and work on cognition were related to higher intervention effects on CRF. The results of this meta-analysis suggest options to maximize the intervention effects of psychosocial interventions for CRF. The effects of yoga and mindfulness-based interventions for CRF appear to be independent of their design, although the limited number of studies points to the need for further research.

The aim of the study was to determine predictors that influence health-related quality of life (HRQOL) in a large cohort of elderly diabetes patients from primary care over a follow-up period of five years. At the baseline measurement of the ESTHER cohort study (2000–2002), 1375 out of 9953 participants suffered from diabetes (13.8%). 1057 of these diabetes patients responded to the second-follow up (2005–2007). HRQOL at baseline and follow-up was measured using the SF-12; mental component scores (MCS) and physical component scores (PCS) were calculated; multiple linear regression models were used to determine predictors of HRQOL at follow-up. As possible predictors for HRQOL, the following baseline variables were examined: treatment with insulin, glycated hemoglobin (HbA1c), number of diabetes related complications, number of comorbid diseases, Body-Mass-Index (BMI), depression and HRQOL. Regression analyses were adjusted for sociodemographic variables and smoking status. 1034 patients (97.8%) responded to the SF-12 both at baseline and after five years and were therefore included in the study. Regression analyses indicated that significant predictors of decreased MCS were a lower HRQOL, a higher number of diabetes related complications and a reported history of depression at baseline. Complications, BMI, smoking and HRQOL at baseline significantly predicted PCS at the five year follow-up. Our findings expand evidence from previous cross-sectional data indicating that in elderly diabetes patients, depression, diabetes related complications, smoking and BMI are temporally predictive for HRQOL.

Purpose: The main aim of the study was to explore the expectations and knowledge of advanced-stage cancer patients about immunotherapy.Methods: This mixed methods study included 53 cancer patients on immune checkpoint inhibitors (ICIs), 55 cancer patients undergoing chemotherapy (CT), and 53 non-cancer patients. Participants’ expectations about ICIs and CT were compared. Additional qualitative data were derived from semi-structured interviews.Results: Among patients who did not receive ICIs, 63 (58%) had never heard of ICIs and 94 (87%) had large gaps in their knowledge of ICIs. Among ICI patients, 33 (62%) simply described ICIs without errors. ICI perception was positive, regardless of whether respondents received or had heard of ICIs, which became particularly evident when compared to CT. ICIs were rated as more promising, and all adverse effects were expected to be significantly lower than those of CT. Knowledge about ICIs was also limited in the interviewed ICI patients. Some patients reported adverse effects of ICIs that were mostly mild and well-tolerated or easily treated.Conclusions: The lack of understanding of ICIs should be improved by activities to increase the knowledge of ICI patients and the general population. In contrast to CT, ICIs invoked fewer negative associations with efficacy and toxicity. Therefore, attention should be paid to risk awareness when educating patients.

Background: This prospective multicenter study aimed to investigate the courses of positive support (PS) and detrimental interaction (DI), two different aspects of social support, and the relation between social support and psychosocial distress and/or health-related quality of life (HRQOL) in a large sample of patients with different cancers. Methods: For this observational study, we enrolled adult patients with cancer from 13 comprehensive cancer centers (CCCs) in Germany. We included a total of 1087 patients in our analysis. We assessed the outcomes via standardized self-report questionnaires at three measurement points: at admission for acute care (T1), 6 (T2) and 12 months (T3) thereafter. Our outcome variables included PS and DI, depression and anxiety symptoms, distress, mental quality of life (MQoL) and physical QoL (PQoL). Data were analyzed using three-level hierarchical linear modeling (HLM) and group-based trajectory modeling. Results: During the first year after the cancer diagnosis, both PS and DI decreased in our sample. Baseline depression symptom severity was a significant predictor of PS and DI. Further analyses revealed significant associations between PS, DI and the course of depression and anxiety symptoms, and MQoL. PS buffered the negative effects of DI with regards to these variables. Low DI was associated with better PQoL, whereas PS was not. In general, the impact of social support on psychosocial outcomes was weak to moderate. Conclusions: Our findings provide evidence for the influence of PS and DI on psychosocial symptoms and HRQOL, and emphasize the importance of psycho-oncological interventions that strengthen PS and prevent or reduce DI for patients with cancer and their relatives.

Objective: The aim of the study was to assess the longitudinal association between cardiovascular risk factors including albuminuria and other variables (e.g. awareness of hypertension, number of types of antihypertensive drugs, comorbidity), and health-related quality of life (HRQOL) in a large cohort of patients with hypertension, over a follow-up period of 5 years. Methods: Nine thousand nine hundred and fifty-three participants of the ESTHER (Epidemiologische Studie zu Chancen der Verhutung, Fruherkennung und optimierten Therapie chronischer Erkrankungen) study - a population-based cohort study of middle-aged and older adults aged 50-74 years at baseline were recruited by general practitioners (GPs) in 2000-2002 and included in the follow-up (2005-2007). HRQOL at baseline and follow-up was measured using the Short-Form General Health Survey (SF-12). Mental component scores (MCS) and physical component scores (PCS) were calculated. Multiple linear regression models were used to determine longitudinal predictors of HRQOL at follow-up. Results: Four thousand, two hundred and three patients with hypertension (98.2%) responded to the SF-12 both at baseline and after 5 years and were therefore included in the study. Smoking status, BMI, diabetes, macroalbuminuria, comorbid diseases, history of depression, and lower HRQOL at baseline predicted lower PCS at the 5-year follow-up. Lower MCS after 5 years was predicted by smoking status, dyslipidaemia, a reported history of depression, and HRQOL at baseline. No significant association was detected between awareness of hypertension and any HRQOL component score after 5 years. Conclusions: Macroalbuminuria and other variables related to increased cardiovascular risk have a negative impact on PCS. Suggestions of a link of treatment and awareness of hypertension with HRQOL from previous cross-sectional studies are not supported by our longitudinal findings.
