Effects of a digital intervention on physical activity in adults: A randomized controlled trial in a large-scale sample.

Background: Physical inactivity is associated with health risks, contributing to various diseases and all-cause mortality. Despite recommendations for regular physical activity (PA), many adults remain inactive, influenced by socioeconomic and environmental factors. Digital interventions, particularly web-based PA programs, offer promising possibilities to promote PA across populations.

Health Effects of a 12-Week Web-Based Lifestyle Intervention for Physically Inactive and Overweight or Obese Adults: Study Protocol of Two Randomized Controlled Clinical Trials.

Web-based lifestyle interventions have attracted considerable research interest. Available evidence on such interventions suggests health-promoting effects, but further research is needed. Therefore, this study aims to investigate short-, medium-, and long-term health effects of a web-based health program ("TK-HealthCoach", TK-HC) offered by a national statutory health insurance fund (Techniker Krankenkasse, TK).

Effectiveness of an interactive web-based health program for adults: a study protocol for three concurrent controlled-randomized trials (EVA-TK-Coach).

Background: A healthy lifestyle can help prevent diseases that impair quality of life and lead to premature death. The Techniker health insurance fund offers a comprehensive online health program to support users in achieving their health goals of Increasing Fitness, Losing and Maintaining Weight, or Smoking Cessation.

Methods: The aim of this study is to test the long-term effectiveness of the web-based TK-HealthCoach with regard to the primary outcomes of increased physical activity, sustainable weight reduction, and smoking abstinence.

Evaluation of a Mobile Phone App for Patients With Pollen-Related Allergic Rhinitis: Prospective Longitudinal Field Study.

Background: Mobile health apps have great potential to support the self-management of chronic conditions such as allergic diseases, which constitute significant challenges in health care. However, the health app market is confusing for users, as it is vast, dynamic, and lacks scientific evidence regarding the effectiveness of the apps on offer. To our knowledge, no health app for pollen-related allergic rhinitis has been evaluated.

Visualisation of metastatic oesophageal and gastric cancer and prediction of clinical response to palliative chemotherapy using 18FDG PET.

Aim: This study assessed the value of (18)F-deoxyglucose positron emission tomography (FDG-PET) for visualisation and early metabolic response assessment in metastatic gastro-oesophageal cancer.

Patients, Methods: Twenty-six patients who were treated for metastatic disease (20 adenocarcinomas, 6 squamous cell cancers) underwent FDG-PET before and two weeks after the onset of palliative chemotherapy with either oxaliplatin + 5-FU/LV or with docetaxel + capecitabine. PET results were validated according to clinical response based on RECIST criteria.
