Osteoporosis (OP), which is characterized by a decrease in bone density and increased susceptibility to fractures, is closely linked to the gut microbiota (GM). It is increasingly realized that the GM plays a key role in the maintenance of the functioning of multiple organs, including bone, by producing bioactive metabolites such as short-chain fatty acids (SCFA). Consequently, imbalances in the GM, referred to as dysbiosis, have been identified with a significant reduction in beneficial metabolites, such as decreased SCFA associated with increased chronic inflammatory processes, including the activation of NF-κB at the epigenetic level, which is recognized as the main cause of many chronic diseases, including OP. Furthermore, regular or long-term medications such as antibiotics and many non-antibiotics such as proton pump inhibitors, chemotherapy, and NSAIDs, have been found to contribute to the development of dysbiosis, highlighting an urgent need for new treatment approaches. A promising preventive and adjuvant approach is to combat dysbiosis with natural polyphenols such as resveratrol, which have prebiotic functions and ensure an optimal microenvironment for beneficial GM. Resveratrol offers a range of benefits, including anti-inflammatory, anti-oxidant, analgesic, and prebiotic effects. In particular, the GM has been shown to convert resveratrol, into highly metabolically active molecules with even more potent beneficial properties, supporting a synergistic polyphenol–GM axis. This review addresses the question of how the GM can enhance the effects of resveratrol and how resveratrol, as an epigenetic modulator, can promote the growth and diversity of beneficial GM, thus providing important insights for the prevention and co-treatment of OP.

Breast cancer (BC) is currently one of the most common cancers in women worldwide with a rising tendency. Epigenetics, generally inherited variations in gene expression that occur independently of changes in DNA sequence, and their disruption could be one of the main causes of BC due to inflammatory processes often associated with different lifestyle habits. In particular, hormone therapies are often indicated for hormone-positive BC, which accounts for more than 50–80% of all BC subtypes. Although the cure rate in the early stage is more than 70%, serious negative side effects such as secondary osteoporosis (OP) due to induced estrogen deficiency and chemotherapy are increasingly reported. Approaches to the management of secondary OP in BC patients comprise adjunctive therapy with bisphosphonates, non-steroidal anti-inflammatory drugs (NSAIDs), and cortisone, which partially reduce bone resorption and musculoskeletal pain but which are not capable of stimulating the necessary intrinsic bone regeneration. Therefore, there is a great therapeutic need for novel multitarget treatment strategies for BC which hold back the risk of secondary OP. In this review, resveratrol, a multitargeting polyphenol that has been discussed as a phytoestrogen with anti-inflammatory and anti-tumor effects at the epigenetic level, is presented as a potential adjunct to both support BC therapy and prevent osteoporotic risks by positively promoting intrinsic regeneration. In this context, resveratrol is also known for its unique role as an epigenetic modifier in the regulation of essential signaling processes—both due to its catabolic effect on BC and its anabolic effect on bone tissue.

Background: Occupational stress among emergency medical staff remains a central problem. Prior to the COVID-19 pandemic, many studies were focused on the working conditions of clinical emergency staff, but few examined the occupational stress profiles of prehospital emergency dispatchers (ED). The aim of this study is therefore to provide baseline data on the differences in occupational stress profiles between prehospital and clinical emergency medical staff. Methods: ED, emergency nurses (EN), and trauma surgeons on duty (TS) were questioned using the established and validated standardized short version of the instrument for stress-related job analysis for hospital physicians (ISAK-K). Differences between occupational groups were compared using the Mann–Whitney U test. Results: Our data indicate significant differences in perception of stressors between professional groups ( p < 0.05), with ED showing the highest psychological stress, followed by EN. Social stressors and emotional dissonance were significantly higher in ED and EN compared to TS ( p < 0.05). Time pressure was identified as major stressor for ED and TS, but not for EN ( p < 0.01). All professions showed moderate high levels of uncertainty and frustration ( p = n.s.). Support from colleagues and supervisors was the greatest positive resource for all professional groups ( p = n.s.). Conclusion: In accordance with current literature, our results advocate for a re-evaluation of the identified stressors, as ED, EN, and TS continue to show high levels of occupational stress. Training programs for coping with emotional dissonance and social stressors are likely to be crucial for reducing job stress among ED and EN.
