Impaired wound healing is one of the unsolved problems of modern medicine, affecting patients’ quality of life and causing serious economic losses. Impaired wound healing can manifest itself in the form of chronic skin wounds or hypertrophic scars. Research on the biology and physiology of skin wound healing disorders is actively continuing, but, unfortunately, a single understanding has not been developed. The attention of clinicians to the biological and physiological aspects of wound healing in the skin is necessary for the search for new and effective methods of prevention and treatment of its consequences. In addition, it is important to update knowledge about genetic and non-genetic factors predisposing to impaired wound healing in order to identify risk levels and develop personalized strategies for managing such patients. Wound healing is a very complex process involving several overlapping stages and involving many factors. This thematic review focuses on the extracellular matrix of the skin, in particular its role in wound healing. The authors analyzed the results of fundamental research in recent years, finding promising potential for their transition into real clinical practice.

Dupuytren's disease (DD) is a common multifactorial disease accompanied by deformity of the hand with flexion contracture of one or more fingers, limitation of their mobility and a fixed lesion. This disease refers to disorders of the connective tissue. Objective: to generalize the results of studies of environmental risk factors for DD and update existing ideas about modifiable and non-modifiable predictors of the disease in adults. Methods. We searched for full-text English-language publications in the PubMed, Springer, Scopus, Clinical Keys, Oxford Press, Google Scholar, eLIBRARY. Results. The most significant modifiable predictors of the development of DD include (top 5): occupation; hobby; lifestyle; comorbid diseases; drugs. Non-modifiable predictors include (top 5): gender; age; ethnos; race; genetics. Genetic predictors of DD are not well understood, but the number of candidate genes responsible for the development of DD is increasing and reaches the top 50 or more candidate genes with a statistically significant association with the risk of developing DD in adults. The most studied candidate genes are DUPC1, MMP2, MMP9, TIMP1, TIMP2, WNT4, WNT7B. Discussion. Primary and secondary prevention of DD requires accounting of the mutual influence of modifiable and non-modifiable predictors in the disease development, as well as a personalized approach in planning and choosing non-surgical and surgical treatment, as well as the carriage of single nucleotide variants (SNVs) candidate genes associated with the development of DD. A promising direction in the prevention of disabling complications of DD may be the development of decision-making information programs (personalized algorithms) that take into account non-genetic and genetic predictors in a particular person, and their implementation in real clinical practice. Conclusion. Large multicenteral studies of the influence and mutual influence of modifiable and non-modifiable predictors with a single design are required in the future.
