Urban development and tourism in the mediterranean region: opportunities and strategies of european planning

Objectives | In recent years tourism has become increasingly the object of interest related to the themes of sustainability and accountability. Sustainability and accountability are key themes and a central node of urban planning, drawing the attention of experts on the role of tourism as a potential territorial policy component which can interact with the different potential and critical development issues of the territory. The report presents two main research projects “AhlanWa Sahlan” and “SISLAB” undertaken by the Department of Urban and Regional Planning (DPTU) of the Faculty of Architecture “La Sapienza” University, proposed for the opportunities offered by European institutions for financing. The two research projects proposed for the Mediterranean area consider different points of view about tourism issues. The “Ahlan Wa Sahlan” project considers tourism as a potential component driving the regional policy to the recovery and development of tangible and intangible heritage of the historic urban centres involved. The “SISLAB” project highlights the problems related to mass tourism as an economic resource but also, and above all, as a serious problem threatening fragile environment and landscape, such as small Mediterranean islands subjected to tourism over pressure, sometimes unsustainable, during the tourist season peaks. The strategy proposed in the “AhlanWa Sahlan” project is focussed on the activation of recovery processes and exploitation of architectural heritage (housing) and fostering the economy through concerted actions and governance. The second search path “SISLAB” is aimed at the sustainable development of the territory through “green energy” experimental projects as local economic alternatives to tourism interacting with it in the planning and management process.  In both europrojects the overall objectives are: – increase the level of entrepreneurial cooperation among the different countries involved, as well as the collaboration between public administrations and the entrepreneurial sectors of the whole area; – strengthen the informative and technological relationships between those responsible for culture, tourism and other sectors of the economic and social activities related to activities of tourism; – promote tourism as an incentive to interpersonal and inter-cultural relationship among the peoples of the Mediterranean region; – define strategies for the maintenance and exploitation of environmental, territorial and urban resources and autochthonous cultures, minimizing the effects of mass tourism. Methodology | Based on the “learning by doing” methodology, the projects build a collective journey, based on cooperation among different sectors (cultural, social, business, entrepreneurship) and networking with civil society that proposes a Mediterranean Approach to local development, firmly secured on the role of education – in terms of cultural heritage, environment and city – and on the principles of equality and mutual understanding. In this difficult historical moment – marked also by the results induced by the global recession – it appears essential to claim a double function for tourism: 1. A factor for local development, as it envisages the re-territorialisation of the economy, reporting proceeds in the community that produces it; 2. A factor of social cohesion and cultural integration among the countries of the area, because it stimulates personal and cultural relations among different people. Main results and contributions | Unfortunately, the development of mass tourism – produced in the Mediterranean from the 1960s onwards and based primarily on seasonal climatic offerings – has produced serious economic, cultural and environmental imbalances, some of which are irreversible. Progressively, however, contemporary society has become aware of the value of maintaining the environment and autochthonous cultures to the point that, today, any sustainable initiative related to the field of tourism in the Mediterranean region must contemplate the necessary measures to preserve its cultural and environmental heritage. In line with the geopolitical order of the Mediterranean, the partnership of both projects therefore believes that it is essential to: – increase the level of entrepreneurial cooperation among the different countries involved, as well as the collaboration between public administrations and the entrepreneurial sectors of the whole area; – strengthen the informative and technological relationships between those responsible for culture, tourism and other sectors of the economic and social activities related to activities of tourism; – promote tourism as an incentive to interpersonal and inter-cultural relationship among the peoples of the Mediterranean region; – define strategies for the maintenance and exploitation of environmental, territorial and urban resources and autochthonous cultures, minimizing the effects of mass tourism. Limitations | The lack of a mutual understanding and cooperation between all those responsible for the projects and the local authorities, experts, technicians, citizens, etc.; the lack of collaboration with local authorities and their unwillingness to provide the necessary permits would prejudice the results of the projects; the lack interest, and consequent participation, by institutions, students, local citizens and actors in the projects. Conclusions | The revitalization of urban areas and the heritage of related activities, together with the promotion of sustainable tourism, as it is known,can activate dynamics of economic sustainability and the reduction of social disparities that, besides opposing migratory phenomenon caused by unemployment, re-territorializes the economy and re-composes cultural identity, bringing the historical-cultural characteristics of local identities to the “centre” of the logics of territorial development and growth. In particular, investing in integrated relational tourism, creates a driving force for the systemic development, in a key of territorial sustainability, with specific reference to the cultural resources of anthropic and natural environment. It deals with a review of the very concept of tourism, understood as a promoter of interpersonal relationships and, at the same time, as an opportunity for territorial development through the planning of processes of exploitation, maintenance and recovery of manifold territorial realities capable of recounting the history of Mediterranean man through craftsmanship, agriculture and cultural heritage

"Water or not water: That is the question." Analysis of costs and consumption of the operating theaters in a greener perspective

Objective: To compare the amounts of water and plastic used in surgical hand washing with medicated soaps and with alcohol-based products and to compare costs and consumption in a year, based on scheduled surgical activity. Method: This retrospective study was carried out at Udine's Gynecology Operating Block from October to November 2022. We estimated the average amount of water with a graduated cylinder and the total cost of water usage based on euros/m3 indicated by the supplier; for each antiseptic agent we collected the data relevant to wash time, amount of water and product used per scrub, number of handscrubs made with every 500 mL bottle and cost of a single bottle. We put data into two hypothetical contexts, namely WHO guidelines and manufacturers' recommendations. Data were subjected to statistical analysis. Results: The daily amount of water using povidone-iodine, chlorhexidine-gluconate and alcohol-based antiseptic agents was 187.6, 140.7 and 0 L/day (P value = 0.001), respectively; A total of 69 000 L/year of water would be saved if alcohol-based products were routinely used. A single unit of an alcohol-based product allows three times as many handscrubs as any other product (P value = 0.001) with consequent reduction in plastic packaging. Conclusion: Despite the cost saving being negligible, choosing alcohol-based handrub over medicated soap handrub - on equal antiseptic efficacy grounds - could lead to a significant saving of water and plastic, thus making our operating theaters more environmentally friendly

Fertility sparing treatment for bilateral borderline ovarian tumor. A case report and management strategy explication

A bilateral adnexal mass with suspected carcinosis could be a challenging experience for the gynecologist especially in fertile age and in patients with a desire for pregnancy. A 26-year-old patient who came to the outpatient clinical observation for bilateral, multilocular pelvic masses, with more than 4 papillary structures, color score 2, hypomobile compared to the uterus and rectum, respectively of 65 and 68mm in maximum diameter, free liquid in the abdomen and suspected for ovarian neoplasm. Positive tumor markers and a strong desire of a Fertility Sparing Treatment (FST). A 2-steps surgical approach managed to perform a diagnosis of bilateral ovarian borderline tumor with implants and a fertility sparing surgery. Harvesting and cryopreserving oocytes prior to the cytoreductive intervention was successfully performed

A Novel Approach for Multiple Material Extrusion in Arthroscopic Knee Surgery

Articular cartilage defects and degenerative diseases are pathological conditions that cause pain and the progressive loss of joint functionalities. The most severe cases are treated through partial or complete joint replacement with prostheses, even if the interest in cartilage regeneration and re-growth methods is steadily increasing. These methods consist of the targeted deposition of biomaterials. Only a few tools have been developed so far for performing these procedures in a minimally invasive way. This work presents an innovative device for the direct deposition of multiple biomaterials in an arthroscopic scenario. The tool is easily handleable and allows the extrusion of three different materials simultaneously. It is also equipped with a flexible tip to reach remote areas of the damaged cartilage. Three channels are arranged coaxially and a spring-based dip-coating approach allows the fabrication and assembly of a bendable polymeric tip. Experimental tests were performed to characterize the tip, showing the ability to bend it up to 90 degrees (using a force of similar to 1.5 N) and to extrude three coaxial biomaterials at the same time with both tip straight and tip fully bent. Rheometric analysis and fluid-dynamic computational simulations were performed to analyze the fluids' behavior; the maximum shear stresses were observed in correspondence to the distal tip and the channel convergence chamber, but with values up to similar to 1.2 kPa, compatible with a safe extrusion of biomaterials, even laden with cells. The cells viability was assessed after the extrusion with Live/Dead assay, confirming the safety of the extrusion procedures. Finally, the tool was tested arthroscopically in a cadaveric knee, demonstrating its ability to deliver the biomaterial in different areas, even ones that are typically hard-to-reach with traditional tools

Does Sexual Function and Quality of Life Improve after Medical Therapy in Women with Endometriosis? A Single-Institution Retrospective Analysis

Background: Endometriosis is a gynecological condition affecting up to 10% of women of reproductive age and characterized by chronic pain. Pain is the major cause of the impairment of quality of life in all aspects of these patients. Previous studies have shown that endometriosis treatment, hormonal or surgical, has proven effective not only in controlling the disease but also in improving symptoms, and we can assume also effective in improving quality of life. Methods: This study evaluates quality of life and sexual function in patients with endometriosis at the time of diagnosis and after 6 months of medical therapy, to assess the impact of treatment on these aspects. We evaluated retrospectively patients with a diagnosis of endometriosis between 2018 and 2020. All patients underwent gynecological examination and transvaginal ultrasound and filled in three questionnaires. The same evaluation was provided after taking medical hormonal therapy. Results: The improvement of dysmenorrhea, chronic pelvic pain, and dyspareunia after medical treatment were statistically significant. Instead, items concerning arousal, lubrication, and sexual satisfaction showed a statistically significant worsening after therapy. Conclusions: We can state that hormone therapy alone is not sufficient to achieve an improvement in the patient's quality of life and sexual function. Emerging evidence suggests that most of these patients showed a central sensibilization phenomenon characterized by an amplification of the response to a peripheral and/or neuropathic nociceptive trigger, which is expressed by hyperalgesia and allodynia. For this reason, in these patients, it is better to adopt a multimodal and multidisciplinary approach, including other professional figures, that acts on pain and also intervenes in all those conditions that contribute to worsening quality of life

Arthroscopic device with bendable tip for the controlled extrusion of hydrogels on cartilage defects

: Advanced tools for the in situ treatment of articular cartilage lesions are attracting a growing interest in both surgery and bioengineering communities. The interest is particularly high concerning the delivery of cell-laden hydrogels. The tools currently available in the state-of-the-art hardly find an effective compromise between treatment accuracy and invasiveness. This paper presents a novel arthroscopic device provided with a bendable tip for the controlled extrusion of cell-laden hydrogels. The device consists of a handheld extruder and a supply unit that allows the extrusion of hydrogels. The extruder is equipped with a disposable, bendable nitinol tip (diameter: 4 mm, length: 92 mm, maximum bending angle: 90°) that guarantees access to hard-to-reach areas of the joint, which are difficult to get to, with conventional arthroscopic instruments. The tip accommodates a biocompatible polymer tube that is directly connected to the cartridge containing the hydrogel, whose plunger is actuated by a volumetric or pneumatic supply unit (both tested, in this study). Three different chondrocyte-laden hydrogels (RGD-modified Vitrogel®, methacrylated gellan gum, and an alginate-gelatine blend) were considered. First, the performance of the device in terms of resolution in hydrogel delivery was assessed, finding values in the range between 4 and 102 μL, with better performance found for the pneumatic supply unit and no significant differences between straight tip and bent tip conditions. Finite element simulations suggested that the shear stresses and pressure levels generated during the extrusion process were compatible with a safe deposition of the hydrogels. Biological analyses confirmed a high chondrocyte viability over a 7-day period after the extrusion of the three cell-laden hydrogel types, with no differences between the two supply units. The arthroscopic device was finally tested ex vivo by nine orthopedic surgeons on human cadaver knees. The device allowed surgeons to easily deliver hydrogels even in hard-to-reach cartilage areas. The outcomes of a questionnaire completed by the surgeons demonstrated a high usability of the device, with an overall preference for the pneumatic supply unit. Our findings provide evidence supporting the future arthroscopic device translation in pre-clinical and clinical scenarios, dealing with osteoarticular treatments

Efficacy and safety of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in ovarian cancer: a systematic review of current evidence

Background: PIPAC is a recent approach for intraperitoneal chemotherapy with promising results for patients with peritoneal carcinomatosis. A systematic review was conducted to assess current evidence on the efficacy and outcomes of PIPAC in patients affected by ovarian cancer. Methods: The study adhered to the PRISMA guidelines. PubMed, Google Scholar and ClinicalTrials.gov were searched up to December 2023. Studies reporting data on patients with OC treated with PIPAC were included in the qualitative analysis. Results: Twenty-one studies and six clinical trials with 932 patients who underwent PIPAC treatment were identified. The reported first access failure was 4.9%. 89.8% of patients underwent one, 60.7% two and 40% received three or more PIPAC cycles. Pathological tumour response was objectivated in 13 studies. Intra-operative complications were reported in 11% of women and post-operative events in 11.5% with a 0.82% of procedure-related mortality. Quality of life scores have been consistently stable or improved during the treatment time. The percentage of OC patients who became amenable for cytoreductive surgery due to the good response after PIPAC treatment for palliative purposes is reported to be 2.3%. Conclusion: The results showed that PIPAC is safe and effective for palliative purposes, with a good pathological tumour response and quality of life. Future prospective studies would be needed to explore the role of this treatment in different stages of the disease, investigating a paradigm shift towards the use of PIPAC with curative intent for women who are not eligible for primary cytoreductive surgery

Microsatellite Instability and Myometrial Infiltration in Low-Grade Endometrial Cancer: A Focus on MMR Heterodimer Dysfunction by a Retrospective Multicentric Italian Study

Background: Recent studies highlight the role of microsatellite instability (MSI) in tumor progression. This study examines the link between MSI, type of loss of function, and disease progression in low-grade endometrial carcinoma clinically confined to the uterus, focusing on myometrial infiltration. Materials and Methods: This retrospective case-control study analyzed data from 144 women treated for clinical stage I low-grade endometrial carcinoma at two university hospitals. Patients were divided into two groups based on microsatellite status: 118 with microsatellite stability (MSS) and 26 with MSI. Immunohistochemical profiling assessed MMR proteins (MLH1, PMS2, MSH2, MSH6). The primary outcome was the presence of myometrial infiltration, and the secondary outcome was the deepness of infiltration. Data were statistically analyzed using Fisher’s exact, Chi-square, and Wilcoxon tests, with logistic regression applied to evaluate the impact of MSI on these outcomes. Results: Myometrial infiltration was present in 96% of MSS and 98% of MSI cases (p = 0.5). However, deep infiltration (≥50%) was more frequent in patients with MSI (38% vs. 19%, p = 0.042). Stratification by heterodimer loss revealed that loss of MLH1/PMS2 was associ- ated with a higher rate of deep infiltration (47%), while loss of MSH2/MSH6 correlated with lower infiltration risk (14%). In multivariate analysis, MSH2/MSH6 loss remained negatively associated with infiltration (OR 0.88; 95% CI 0.80–0.98; p = 0.020), independent of grade and LVSI. Conclusions: In low-grade endometrial carcinomas clinically confined to the uterus, MSI does not increase the overall prevalence of myometrial infiltration but is associated with deeper invasion, especially in cases with MLH1/PMS2 loss. MSI profiling could aid in risk stratification and therapeutic planning, particularly in candidates for fertility-sparing treatment

Scar-Free Laparoscopy in BRCA-Mutated Women

Background and Objectives: BRCA 1 and 2 mutations have a cumulative risk of developing ovarian cancer at 70 years of 41% and 15%, respectively, while a cumulative risk of breast cancer by 80 years of age was 72% for BRCA1 mutation carriers and 69% for BRCA2 mutation carriers. The NCCN recommends risk-reducing salpingo-oophorectomy (RRSO), typically between 35 and 40 years, and upon completion of childbearing in BRCA1 mutation, while it is reasonable to delay RRSO for management of ovarian cancer risk until age 40–45 years in patients with BRCA2. In recent years there have been two main lines of evolution in laparoscopy. The former concerning the development of a single-site laparoscopic and the latter concerning the miniaturisation of laparoscopic instruments (mini/micro-laparoscopy). Materials and Methods: In this case report, we show our experience in prophylactic adnexectomy, on a mutated-BRCA patient, using the MiniLap® percutaneous surgical system. Results: This type of technique is safe and effective and does not require a particular learning curve compared to single-port laparoscopy. Conclusions: The considerable aesthetic advantage of the scars, we believe, albeit to a lesser extent, is useful to find in these patients burdened by an important stress loa
