Manganese (Mn) is an essential trace element with unique functions in the body; it acts as a cofactor for many enzymes involved in energy metabolism, the endogenous antioxidant enzyme systems, neurotransmitter production, and the regulation of reproductive hormones. However, overexposure to Mn is toxic, particularly to the central nervous system (CNS) due to it causing the progressive destruction of nerve cells. Exposure to manganese is widespread and occurs by inhalation, ingestion, or dermal contact. Associations have been observed between Mn accumulation and neurodegenerative diseases such as manganism, Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and amyotrophic lateral sclerosis. People with genetic diseases associated with a mutation in the gene associated with impaired Mn excretion, kidney disease, iron deficiency, or a vegetarian diet are at particular risk of excessive exposure to Mn. This review has collected data on the current knowledge of the source of Mn exposure, the experimental data supporting the dispersive accumulation of Mn in the brain, the controversies surrounding the reference values of biomarkers related to Mn status in different matrices, and the competitiveness of Mn with other metals, such as iron (Fe), magnesium (Mg), zinc (Zn), copper (Cu), lead (Pb), calcium (Ca). The disturbed homeostasis of Mn in the body has been connected with susceptibility to neurodegenerative diseases, fertility, and infectious diseases. The current evidence on the involvement of Mn in metabolic diseases, such as type 2 diabetes mellitus/insulin resistance, osteoporosis, obesity, atherosclerosis, and non-alcoholic fatty liver disease, was collected and discussed.

The goal of burn wound treatment is to ensure rapid epithelialization in superficial burns and the process of rebuilding the lost skin in deep burns. Topical treatment plays an important role. One of the innovations in the field of synthetic materials dedicated to the treatment of burns is epidermal skin substitutes. Since the introduction of Suprathel^®, the alloplastic epidermal substitute, many research results have been published in which the authors investigated the properties and use of this substitute in the treatment of wounds of various origins, including burn wounds. Burn wounds cause both physical and psychological discomfort, which is why ensuring comfort during treatment is extremely important. Alloplastic epidermal substitute, due to its biodegradability, plasticity, no need to remove the dressing until healing, and the associated reduction in pain, is an alternative for treating burns, especially in children.

Dyslipidaemia is a disorder of the lipid metabolism, caused mainly by poor eating habits. The most severe consequence of an inappropriate diet is the development of atherosclerosis and hepatic steatosis. It is generally believed that a change in nutrition, and increased physical activity can eliminate these health problems. The contemporary research and therapies used to treat dyslipidemia mainly focus on lowering the triglyceride and cholesterol levels. However, disturbances in trace element homeostasis or the accumulation of toxic elements can also affect physiological processes, and be involved in the development of metabolically mediated diseases. The present study aimed to determine the mineral profiles of liver and brain tissues collected at autopsy (n = 39) in groups of people with hepatic steatosis (n = 5), atherosclerosis (n = 9), hepatic steatosis, and atherosclerosis (n = 16), and others without the selected disorders (n = 9). Concentrations of 51 elements were analysed via inductively coupled plasma mass spectrometry (ICP-MS) after the initial wet mineralisation of the samples with nitric acid. The results obtained allow us to conclude that the hepatic steatosis group suffers from a deficiency of important trace elements, such as copper, zinc, and molybdenum (p < 0.05), whereas the group with atherosclerosis is characterised by elevated levels of cadmium in the liver tissue (p = 0.01). Analysing the mean values of the element concentrations measured in 11 brain areas, statistically significant higher levels of calcium and copper (p < 0.001) were found in the atherosclerosis group, compared to the hepatic steatosis group, confirming the involvement of these elements in the pathogenesis of atherosclerosis. In addition, an accumulation of cadmium, lead, titanium, and strontium in the brain tissue was observed in the atherosclerosis group. While the accumulation of individual elements differs in different parts of the brain, the differences in the cadmium content (p < 0.05) between the study groups apply to the whole brain, except for the nucleus accumbens septi area, where a statistically significant titanium accumulation occurs in the atherosclerosis and steatosis groups, compared to the others (p < 0.05). In addition, the disruption of elemental homeostasis in the brain of a single case with bipolar disorder, and a case with hip replacement was observed. Our results confirm the involvement of chemical elements in the pathogenesis of selected metabolic diseases, and the need for further studies in larger populations.

Background: Burns in children represent a significant public health issue, as there is no single targeted dressing for the treatment of burn wounds in children. The alloplastic epidermal skin substitute is the dressing of choice for treating burns in children in our burn center. However, it sometimes occurs that the dressing separates from the wound too early, before the process of full re-epithelialization. The inflammatory phase of wound healing seems to be crucial for maintaining the adhesion of the dressing, and thus, changes in parameters such as leukocyte levels and protein changes are of clinical significance. The aim of our study is to find laboratory factors that could contribute to premature dressing separation. Methods: The documentation of 182 children treated for acute burns at a major Polish burn center in the years 2009–2023 was analyzed. A demographic analysis was performed to collect information. The group was split into the following two categories based on the condition of the dressing: “attached to the wound” and “detached from the wound”. Laboratory tests were collected on admission and with control tests 3–5 days after injury. Results: The results indicate that only a few of the parameters studied showed a statistically significant difference between the groups of patients in whom the dressing did or did not attach. The most pronounced relationship was found for the pre-treatment leukocyte level (leuk1). Statistical significance was also demonstrated for hemoglobin levels and changes in protein (protein_diff) and also glucose levels (glucose_diff). Conclusions: Our study shows that there are blood parameters (leukocyte, protein, and glucose levels) that influence the adhesion of the dressing. Unfortunately, there are no other studies on this topic in the literature, so it seems very important to expand research in this direction.

Background: Children make up a large percentage of those affected by burns worldwide, with most of them suffering from severe injuries that necessitate skilled medical attention. Despite medical progress, there is still no ideal dressing for the treatment of burn wounds in children. The aim of the study was to assess the impact of epidermal substitutes in the treatment of burn wounds in children. Materials and Methods: This retrospective study evaluates the use of three dressings in the treatment of pediatric burns at a major Polish burn center. A patient database was used to identify children who received treatment with silver dressings, paraffin dressings or epidermal substitutes from 2009 to 2023. A demographic analysis was performed to collect the following information: causes of burns, procedural details and patient outcomes. Results: There were 439 patients aged between 1 month and 18 years. For severe burns, the number of interventions was lowest among children with epidermal substitute application (p = 0.039). Paraffin gauze resulted in the greatest number of skin grafts, whereas alloplastic replacement produced the least amount of transplantation (p < 0.005) regardless of the severity of the burn. Conclusions: Epidermal substitutes offer a good dressing option for burn wounds to improve their treatment and reduce the need for skin graft coverage. In the future, extended comparative or randomized trials are needed to confirm our results.

Background: Early digit survival after replantation or revascularization may be associated with patient and injury characteristics. This study aimed to identify non-surgical factors associated with early digit survival following traumatic digit injuries. Methods: This retrospective single-center observational study included patients treated for complete or subtotal digit amputations or extensive soft-tissue injuries between 2015 and 2025. The primary outcome was digit survival at hospital discharge. Associations were assessed using multivariable mixed-effects logistic regression with a patient-specific random intercept, adjusting for age, smoking status, injury mechanism, extent of vascular injury, and injury level. Sensitivity analyses excluded single-bundle injuries and separately included only complete amputations. Results: Among 232 patients with 363 injured digits, replantation or revascularization was attempted in 217 digits. Overall, 155 digits survived (71.4%). Survival was 92.9% after single-bundle injuries, 81.5% after two-bundle injuries, and 53.2% after complete amputations. Extent of vascular injury was associated with survival in the adjusted model (global p = 0.026). Complete amputation was associated with lower odds of survival than single-bundle injury (OR 0.015, 95% CI 0.001–0.327; p = 0.008). This association persisted after excluding single-bundle injuries (OR 0.055, 95% CI 0.004–0.663; p = 0.022). No statistically significant adjusted associations were identified for injury mechanism, injury level, smoking, or age, either in the primary model or among complete amputations alone. Conclusions: The extent of vascular injury was the only evaluated factor significantly associated with early digit survival in the adjusted model. Complete amputations had lower odds of survival than injuries retaining tissue continuity. These findings concern survival at hospital discharge and should not be extrapolated to long-term functional outcomes.
