The major challenge facing human society in the 21st century is represented by the environmental crisis. In this context, the present article proposes a sustainable vector model for managing the environmental crisis. It focuses on social, economic, and ecological aspects, with the aim of providing a framework for analysis and adapted solutions. By integrating environmental factors into decision-making processes and public policies, this model aims to improve the quality of life and promote sustainable development. This study presents a comprehensive and cohesive framework for addressing environmental challenges by integrating the Context Triangle and Phenomenon Triangle to develop a sustainable vector model. This novel approach to crisis management aims to provide a holistic and adaptive response to the complex and evolving needs of society and the environment, acknowledging the interconnected nature of environmental issues. The proposed sustainable vector model seeks to understand the trade-offs and synergies between various dimensions of sustainability, ultimately facilitating the development and implementation of more robust and equitable strategies. By incorporating this vector-based approach, the integrated framework can be employed to examine the intricate relationships between different aspects of environmental challenges, fostering a deeper understanding of their interconnected nature and promoting more effective interventions. Moreover, potential advancements may involve fractalizing the integrated framework on multiple levels, allowing for a more elaborate and comprehensive sustainable management approach. By extending the system into a multi-level fractal structure, stakeholders can investigate the relationships between different aspects of environmental challenges, ultimately driving the development of innovative and adaptive strategies that can better address the ever-changing needs of our planet and its inhabitants.

The starting point of this study described in this paper is the desire to create a model that will be useful in various fields related to mathematical modeling and that will contain a new perspective of what we call and know about feedback. This feedback has appeared in cyber studies. The modeling of this computer system involves the transfer of information from the data of a problem written in a practical language to the language specific to the feedback contained in cellular automata and algebraic fractals. Both cellular automata and algebraic fractals are fundamental in the development of technical solutions used in the fields related to quantum mechanics. The bases of these researches are from the articles conceived by Prof. Dr. Colceag, in which he mentions information fields, structural fractals, but also about modeling and the models that emerge from this modeling. All this complex modeling structure will describe more complex objects with characteristics such as: feedback cycles, projective relationships in the projective space and specific transformations that describe how this model was obtained, these being common features for everything that means description and modeling the phenomena of physics, chemistry, biology, economy etc. At the beginning, such a model focuses on feedback cycles, and will also develop commutative diagrams based on automorphisms. After this first phase, the model is organized on progressive levels where its structure is divided into new and stable structures that self-determine, this leading to a fractalized modeling in which a feedback structure is inserted in the form of a loop.

Introduction: Female sex has been shown to be a risk factor for the development of adverse drug reactions; however, this has not been studied for cyclosporine (CsA). The aim of this study was to investigate, in Italian dermatological practice, the influence of gender and menopause and related hormones on the incidence of adverse events (AEs) during CsA treatment in psoriatic patients. Methods: Multicenter, prospective, observational study conducted from May 2011 to June 2013. Patients with plaque psoriasis, undergoing a new CsA administration course, or about to start it, were enrolled in the outpatient clinics of Italian dermatological centers. During the 2–6months of study duration, patients had to note all AEs that occurred in a diary that was reviewed by the investigators at the follow-up visit. Sex hormone levels were measured within 7days from the start date of a menstrual cycle. Results: A total of 969 adult psoriatic patients were enrolled in the study, divided into four cohorts: fertile women and corresponding age-matched men; postmenopausal women and corresponding age-matched men. A significant difference in the percentage of patients with AEs was observed between fertile and postmenopausal women, but not between women and age-matched men. AE incidence rate was about 37% higher in fertile women than in age-matched men and about 18% higher in postmenopausal women than in age-matched men, but differences were not statistically significant. Incidence rate ratio of fertile vs. postmenopausal women was 0.67, reaching statistical significance. AEs were mild or moderate in severity in the great majority of patients of all cohorts and postmenopausal women had significantly less grade 1–2 AEs compared to fertile women, but more grade 3–4 AEs. FSH levels were significantly higher in postmenopausal women reporting no AEs, and DHEA sulfate levels were about 10% higher in men with no AEs, compared to those reporting at least one AE. Cortisol levels were slightly though significantly higher in postmenopausal women with no AE. Conclusions: A better understanding of sex- and hormone-related influences on drug responses may help to improve drug safety and efficacy, by permitting one to tailor pharmacological treatments to individual subjects or defined patient cohorts.

Introduction: Treat-to-target strategies are used in several chronic diseases to improve outcomes. Treatment goals have also been suggested for psoriasis, but there is currently no consensus on targets, and guidance is needed to implement this strategy in clinical practice. The project ‘Treat to Target Italia’ was launched by a scientific board (SB) of 10 psoriasis experts to generate expert consensus recommendations. Methods: On the basis of the published literature, their clinical experience, and the results of a survey among Italian dermatologists, the SB identified four relevant topics: (1) clinical remission; (2) quality of life; (3) abrogation of systemic inflammation; (4) safety. They drafted 20 statements addressing these four topics and submitted them to a panel of 28 dermatologists, in a Delphi process, to achieve consensus (greater than 80% agreement). Results: Consensus was reached on all statements. Treatment goals defining clinical remission should include a 90% improvement from baseline in the Psoriasis Area and Severity Index (PASI90 response) or an absolute PASI score of less than or equal to 3. Patient’s quality of life and satisfaction are important targets. If PASI targets are achieved, there should be no or very low impact of psoriasis on quality of life [Dermatology Life Quality Index (DLQI) score less than or equal to 3]. If PASI or DLQI goals are not achieved within 3–4months, treatment should be changed. Abrogation of systemic inflammation may be crucial for preventing or delaying inflammatory comorbidities. Safety is an equally important target as efficacy. Conclusion: These 20 consensus statements define the parameters of a treat-to-target strategy for psoriasis in Italy. It is hoped that use of these in the management of patients with psoriasis will improve treatment outcomes and patient health-related quality of life.

Cyclosporine (CsA) is an effective and safe therapeutic option in various dermatoses in both adults and children. Over the last 25 years, Italian dermatologists have gained relevant experience about the use of CsA in the treatment of psoriasis and atopic dermatitis, and an Italian Consensus Conference has recently provided recommendations in adult patients. A comparison between these real-world indications and current European guidelines is hereby provided.
