In this review, a compilation of articles in databases on the extraction methods and applications of hyaluronic acid (HA) was carried out. HA is a highly hydrated component of different tissues, including connective, epithelial, and neural. It is an anionic, linear glycosaminoglycan (GAG) primarily found in the native extracellular matrix (ECM) of soft connective tissues. Included in the review were studies on the extraction methods (chemical, enzymatical, combined) of HA, describing advantages and disadvantages as well as news methods of extraction. The applications of HA in food are addressed, including oral supplementation, biomaterials, medical research, and pharmaceutical and cosmetic industry applications. Subsequently, we included a section related to the structure and penetration routes of the skin, with emphasis on the benefits of systems for transdermal drug delivery nanocarriers as promoters of percutaneous absorption. Finally, the future trends on the applications of HA were included. This final section contains the effects before, during, and after the application of HA-based products.

Introduction: Iatrogenic lead perforation is a rare but serious complication of cardiac implantable electronic device (CIED) implantation. Evidence on percutaneous management of subacute or delayed cases remains limited.
Methods: We retrospectively reviewed 38 patients treated for iatrogenic lead perforation between January 2012 and October 2024.

Background: Interventions aimed to increase healthcare provider empathy and capacity to deliver person-centered care have been shown to improve healthcare seeking and outcomes. In the context of self-injectable contraception, empathetic counseling and coaching may be promising approaches for addressing "fear of the needle" among clients interested in using subcutaneous depot medroxyprogesterone (DMPA-SC). In Nigeria, the Delivering Innovation in Self-Care (DISC) project developed and evaluated an empathy-based in-service training and supportive supervision intervention for public sector family (FP) planning providers implemented in conjunction with community-based mobilization.

This study was conducted to investigate the techniques and complications of enlarged uterine extraction during minimally invasive surgery for uterine malignancy. The electronic medical record was queried for patients with uterine malignancy and enlarged uterus (≥ 250 g) who underwent primary hysterectomy with laparoscopic or robotic approach. Statistical analysis was performed using Fisher's exact test for categorical variables and Kruskal-Wallis test for continuous variables.

Aim: To summarize the literature on quantitative measures of physical demands in eldercare, with attention to differences between temporary and permanent workers, and to identify gaps to guide future physiological research.
Methods: We searched Scopus, Web of Science, and PubMed for English and Swedish peer-reviewed studies on physical demands in eldercare. Risk of bias was assessed, and descriptive data extracted.
