(1) Background: Fish is a good source of protein, iron, and zinc, which are key nutrients for infant growth and development, as well as a source of energy for adults and the elderly. Due to mercury contamination in both the terrestrial and aquatic environments, there is a risk that considerable levels of mercury will be ingested by the population, causing undesired illnesses and metabolic symptoms once they reach the body. The purpose of this research was to show and emphasize the hazardous effect of mercury in diverse marine products; (2) Methods: We conducted a comparative, open, randomized, non-interventional study on a study group of 119 adults from varied social and demographic backgrounds to assess the bad repercussions of mercury poisoning from fish consumption. A questionnaire with 18 questions was prepared in order to obtain information about the impact, i.e., the dangers present in fish meat. The research was carried out in Oradea and Bihor County, Romania; (3) Results: The largest age group was between the ages of 25–34, but we had respondents from almost all age groups. Most of them considered the fish healthy (30%) and that the omega-3 fatty acids have beneficial effects on the body (25.10%). More than a half of respondents (55%) were unaware of the hidden danger in fish meat in the form of mercury derivatives. Most respondents (65%) considered that they did not consume enough amounts of fish to suffer the consequences of this phenomenon. More than a half of respondents (59%) agreed that they should have been made aware beforehand by displaying the hazards of excessive intake of some high mercury concentration fish species; (4) Conclusions: It is imperative that the population be informed about dangers of mercury toxicity when consuming fish. Mercury must be gradually eliminated worldwide by replacing it with safer alternatives.

The impact of metabolic syndrome (MS) on stent performance and outcomes of patients underwent percutaneous coronary intervention (PCI), including stent implantation, had not yet been fully established. The aim of the present study was to investigate long-term safety and efficacy of 2nd generation DES vs. other stent types in MS patients underwent successful PCI for an acute coronary event. Descriptive epidemiology, angiographic characteristics and one-year clinical outcomes, including major adverse cardiovascular events (MACE) and target lesion revascularization (TLR) procedures were evaluated according to the stent type inserted for 204 patients. The occurrence of TLR (6.62% vs. 9.43%, p = 0.50) and the composite outcomes (20.52% vs. 24.52%, p = 0.54) did not differ significantly between patients having 2nd generation drug eluting stents (DES) or other stent types implanted at the index procedure. It seems that the PCI in acute coronary syndrome (ACS) is similarly efficient regardless of the stent type, suggesting that for the treatment of ACS in MS patients, all stent types show similar results, in terms of TLR or MACE.

Background: Human cutaneous reactivity exhibits marked inter-individual variability, yet the contribution of constitutional pigmentation traits to short-term skin responses remains incompletely characterized. Fitzpatrick skin phototype reflects stable differences in pigmentation-related traits and may therefore act as a phenotypic modifier of early cutaneous reactivity following topical exposure. Methods: In this controlled human study, 239 healthy volunteers were stratified by Fitzpatrick skin phototype into three groups: I–II (n = 138), III (n = 72), and IV–V (n = 29). A standardized emulgel-based topical provocation model was applied under occlusion to the volar forearm, and cutaneous responses were assessed at 20 min (Test A), 24 h (Test B), and 96 h (Test C) using standardized visual scoring. Group comparisons, multivariable linear regression models adjusted for age, sex, country of origin, and experimental lot, and stratified analyses by country of origin, were performed. Results: Early and short-term cutaneous responses differed significantly across phototype groups. Participants with phototypes I–II exhibited higher response scores at both 20 min and 24 h compared with phototype III (p < 0.001). In adjusted models, phototype III remained independently associated with significantly lower reactivity relative to phototypes I–II at 20 min (β = −1.61, p < 0.001) and 24 h (β = −0.98, p < 0.001). Responses among phototypes IV–V were minimal to absent; however, this subgroup was underrepresented, and findings for IV–V are descriptive. Age was a significant positive predictor of response intensity, whereas sex showed no independent association. No persistent reactions were observed at 96 h in any phototype group. Stratified analyses confirmed that the reduced reactivity associated with phototype III was independent of country of origin. Conclusions: Fitzpatrick skin phototype is independently associated with early and short-term cutaneous reactivity following standardized topical provocation in humans. Lighter phototypes (I–II) demonstrate increased susceptibility to transient inflammatory responses, whereas phototype III shows markedly reduced reactivity. These findings support the role of skin phototype as a constitutional modifier of short-term cutaneous responses and highlight the importance of considering pigmentation-related phenotypes in the design and interpretation of dermatological testing, cosmetic tolerability studies, and safety assessments of topical formulations.

Background: The treatment of bacterial dermatological diseases is currently facing major difficulties, determined by the alarming increase in the resistance of pathogenic bacteria to conventional therapies. In this context, a viable and effective alternative is represented by the use of phytocompounds to obtain the desired therapeutic effect. The essential oil of Origanum vulgare L. stands out for its antibacterial, anti-aging, collagen synthesis stimulating and wound healing properties. However, its use is limited by certain disadvantages, such as poor stability and the risk of skin irritation due to accumulation in the dermis. Method: The process of formulating the emulgel with oregano oil respected the specific technological steps. The resulting emulgel was subjected to a series of tests, including organoleptic, stability and antimicrobial efficacy determinations. In addition, an in vivo study was conducted to confirm the lack of irritation, involving six groups of patients differentiated by age, sex and skin phenotype. Results: The test results revealed that the emulgel formulated with oregano oil is stable, has organoleptic properties and an appropriate pH for topical use. The product demonstrated antibacterial efficacy against Staphylococcus aureus and Pseudomonas aeruginosa. In addition, short-term in vivo tests (20 min—96 h) confirmed the safety and absence of skin irritation, indicating its potential as an effective alternative treatment. Conclusions: In conclusion, the emulgel with origanum oil represents an innovative formulation for topical application. The product is well tolerated by the skin and does not cause irritation, and its antibacterial properties validate it as a promising therapeutic solution.
