Introduction: Overweight and a lack of physical activity not only increase the risk of recurrence in breast cancer patients but also negatively impact overall and long-term survival, as well as quality of life. The results presented here are the first real-world data from the DiGA PINK! Coach examining the physical activity and BMI of app users. Based on the literature, an approximate weight gain of 10% over 6 months and a decrease in physical activity can be expected. The purpose of this study is to retrospectively investigate the effects of the PINK! Coach in a real-world setting on patients’ BMI and physical activity level during acute therapies. such as chemotherapy (CHT) and antihormone therapy (AHT). Material and Methods: The PINK! Coach app accompanies breast cancer patients during and after acute therapy to bring about a sustainable lifestyle change. The patients are encouraged to establish a healthy diet, become physically active, and make informed decisions. In this study, real-world data from the app were analyzed over 6 months from baseline to T1 (after 12 weeks) and T2 (after 24 weeks). The patients were under acute therapy or in follow-up care receiving either CHT or AHT. Results: The analyzed data indicate that all patients were able to maintain a consistent BMI over 6 months independent of pre-defined subgroups such as AHT, CHT, or BMI subgroups. In the subgroup of patients undergoing AHT, overweight patients were even able to significantly reduce their BMI by 1-score-point over 6 months (p < 0.01). The subgroup of patients undergoing CHT also showed an significant overall reduction in BMI (p = 0.01). All patients were also able to significantly increase their daily step count as well as their physical activity minutes per day. After the first 12 weeks, 41.4% of patients experienced weight gain, 33.4% were able to maintain their weight, and 24.2% reduced their weight. Conclusion: The presented data provides intriguing insights into the users of the PINK! Coach app and the impact of this usage in regards to BMI and physical activity. At the current time, there are only a few effective concepts for encouraging all breast cancer patients to engage in moderate physical activity and reduce body weight. Often, these concepts apply to selected patient groups. The data presented here include all age groups, tumor stages, and therapies, providing an initial insight into a comprehensive approach. Data over an even longer period would be one way to better contextualize the results in current research.

Worldwide, nearly 200 million children younger than 5 years old suffer from stunting and wasting, 2 different types of undernutrition. Moreover, 45% of deaths among children in that age group are associated with these conditions. Severe acute malnutrition (SAM) refers to children with a weight-for-height z score < −3, a midupper arm circumference < 115 mm, or the presence of bilateral edema, and is especially prevalent in low- and middle-income countries. Undernutrition in children can have a major impact on both their physical and cognitive development. It can lead to infections and death if it remains undetected or untreated. The use of therapeutic feeds is an important component in the management of SAM, which remains a challenge in poorly resourced countries. The aim of this review was to assess the alternatives to the standard therapeutic foods used to treat SAM and to summarize their advantages and disadvantages, providing an overview of current research. A literature search was performed from September to November 2022 using PubMed, the Trip medical database, and the German Institute for Medical Documentation and Information (DIMDI). This review includes 13 randomized controlled trials testing alternatives to the standard therapeutic foods used to treat SAM by using alternative ingredients or a reduced dosage. The results show that, while a few alternative ready-to-use therapeutic food formulas lead to recovery rates similar to those seen with the standard protocol, many alternatives were less effective in the affected children. Thus, the evidence is not yet strong enough to change the World Health Organization’s guidelines. The review identifies promising results of treatment alternatives related to treatment outcomes and costs. Additional research should focus on the interventions that positively impact the recovery process of severely malnourished children to facilitate the treatment and enable greater treatment coverage worldwide.
