This paper presents a novel algorithm with improved convergence and robustness for the pressure-driven modeling of water distribution networks (WDNs), to be implemented as hydraulic engine in the fourth release of the SWANP version 4.0 software. The innovative approach is based on increasing the order of convergence, which is quadratic for algorithms obtained from the Newton Raphson linearization of the equations for WDN resolution. As an example, the cubic order of convergence is obtained by evaluating system matrices at the generic iteration in a more refined way to account for the curvature of the hyperplane associated with the system in the direction of the Newton Raphson step. To show the benefits of the methodology, a third-order algorithm is constructed and compared with a traditional second-order. Both algorithms are based on the direct pressure-driven formulation expressing outflows as a function of service pressure and are equipped with the dampening of the Newton Raphson step. Applications on two case studies of different size, in which challenging pressure-driven conditions are created through demand amplification and segment isolation scenarios, prove that the methodology always reduces the total number of iterations required for convergence and the application of the step dampening. Overall, the results also show that the more stable convergence behavior is accompanied by an appreciable reduction in computation times. Further analyses proved that the third-order algorithm has similar convergence properties to algorithms based on the inverse pressure-driven formulation recently proposed in the scientific literature and can therefore be considered as a valid alternative to these algorithms.

Mud flows represent one of the major causes of natural hazards in mountain regions. Similarly to debris flows, they consist of a hyper-concentrated mixture of water and sediments flowing down a slope and may cause serious damages to people and structures. The present paper investigates the force produced by a dam-break wave of mud impacting against a rigid wall. A power-law shear-thinning model is used to describe the rheology of the hyper-concentrated mixture. A one-dimensional shallow water model is adopted and a second-order Finite Volume scheme is employed to numerically solve the governing equations. The results indicate that depending on the fluid rheological parameters and on the bottom slope, there exists a minimum value of the wall distance above which the peak force does not exceed the asymptotic value of the hydrostatic final condition. For two different values of the channel slope, the dimensionless value of this lower bound is individuated for several values of the power-law exponent and of a dimensionless Basal Drag coefficient. An estimation of the maximum peak force for wall distance smaller than the minimum value is also provided.

- Abstract
Aberrant gene expression due to dysfunction in proteins involved in transcriptional regulation is a hallmark of tumor development. Indeed, targeting transcriptional regulators represents an emerging approach in cancer therapeutics. Lens epithelium-derived growth factor (LEDGF/p75, PSIP1) is a co-transcriptional activator that tethers several proteins to the chromatin. LEDGF/p75 has been implicated in diseases such as HIV infection and KMT2A-rearranged leukemia. Notably, LEDGF/p75 is upregulated in various human cancers including prostate and breast cancer. In this review, we discuss the essential role of LEDGF/p75 in different malignancies and explore its mechanistic contribution to tumorigenesis revealing its potential as a therapeutic target for chemotherapy., Competing Interests: Declaration of competing interest None of the authors declare a conflict of interest., (Copyright © 2024 Elsevier B.V.

- Abstract
Sarcopenia is a geriatric syndrome characterized by a progressive loss of systemic muscle mass and decreased muscle strength or physical function. Several conditions have a role in its pathogenesis, significantly impacting adverse outcomes such as falls, functional decline, frailty, disability, multiple hospitalizations, and mortality. In the oncological setting, sarcopenia is associated with an increased risk of treatment toxicity, postoperative complications, and a higher mortality rate related to other causes (e.g., pneumonia). In the hematological field, even more so, sarcopenia predicts toxicity and response to treatments. In patients with hematologic malignancy, low muscle mass is associated with adverse outcomes and is a predictor of overall survival and non-relapse mortality. Therefore, it is essential to correctly recognize sarcopenia, evaluate the risk factors and their impact on the patient's trajectory, and effectively treat sarcopenia. Sarcopenia is a reversible condition. The most effective intervention for reversing it is physical exercise combined with nutrition. The objective of clinical assessment focused on sarcopenia is to be able to carry out a "tailor-made treatment".

- Abstract
Asthma is a heterogeneous inflammatory disease characterized by abnormalities in immune response. Due to the inherent complexity of the disease and the presence of comorbidities, asthma control is often difficult to obtain. In asthmatic patients, an increased prevalence of irregular menstrual cycles, infertility, obesity, and insulin resistance has been reported. Given that these conditions are also common in patients with polycystic ovary syndrome (PCOS), we propose the definition of "asthma-PCOS overlap syndrome" to indicate a medical condition which shares characteristics of both diseases. The aim of this review is to analyze the links between asthma and PCOS and evaluate the therapeutic role of myo-inositol, a natural compound currently utilized in patients with PCOS, in the management of asthma patients.

- Abstract
Introduction: Approximately a third of cancer-related deaths are attributable to modifiable factors., Methods: As a pilot experience, a cross-sectional survey was conducted in 8,000 citizens residing in four different municipalities of the Salerno province (Sarno, Pagani, San Valentino Torio, and San Marzano sul Sarno) to investigate key lifestyle and dietary habits., Results: A total of 703 of participants (8.7%) reported a history of malignancy. Alarmingly, 30.5% declared to be a current smoker, while 78.8% did not report any kind of physical activity. Encouragingly, 64.5% declared to be abstemious, and 83.0% declared to consume fruit and vegetables every day, while 4.7% and 31.9% declared not to consume meat and fried food, respectively, at any time. Never-consumers of fruit and vegetables had higher odds of having a history of colorectal cancer (OR = 5.01; 95% CI = 1.46-17.15; p = 0.01)., Conclusions: The PREVES study has served to prove the validity of an operational model allowing to integrate hospital and territorial healthcare services, which we expect to be applied at a larger scale. Key information regarding dietary and lifestyle habits of the investigated population was obtained. Larger studies conducted using more accurate approaches to investigate diet, such as 24-h recalls and food frequency questionnaires, are warranted., (© 2023 S. Karger AG, Basel.)

- Abstract
Currently, the management of older cancer patients is directed by a personalized approach and, where possible, a tailor-made treatment. Based on our previous experiences and considering the opportunity of combining a geriatric department and a radiation-oncology department, we have developed a path that follows the patient from the beginning of the treatment, taking into account the complications/late toxicities and the survivors. This study aimed to evaluate the impact of remodeling and restructuring some oncology, radiotherapy, and geriatrics services based on the primary evidence for managing older cancer patients. In 2020, Gemelli ART underwent 60,319 radiation-oncology treatments, admitted 943 patients in the radiation-oncology and supportive care ward, and treated and followed 15,268 patients in clinics. The average length of stay of the admitted patients was reduced from 20.6 days to 13.2 days. In 2021, 1196 patients were assessed for frailty, 847 were admitted for toxicity, and 349 patients were evaluated within the geriatric oncology and supportive care outpatient clinic, and it was found that 59.2% were fit, 31.6% were vulnerable, and 9.2% were frail. This experience has shown a reduction in hospitalizations and the average hospital stay of patients in the case of side effects, a high toxicity to treatments, and the possibility of treating patients with a high level of complexity. This approach should represent the future target of geriatric oncology with the global management of older or complex patients with cancer.

- Abstract
Introduction: A clinical ethics committee (CEC) has educational, regulatory, advisory, mediation, and reflexive functions. As any health care service, the consults with the CEC should be subjected to review and quality improvement. The study objectives were to assess the feasibility, effectiveness, and satisfaction with the bioethical recommendations made by the CEC and assess their impact on the treating team and the patient's family., Population and Methods: Descriptive, retrospective, qualitative, and quantitative study of clinical cases submitted to the hospital's CEC between January 1st, 2013 and December 31st, 2017 using data from the CEC minute book, medical records, registries from the Office for Remote Communication, and semi-structured interviews with health care team members., Results: A total of 108 cases (106 patients) were analyzed: 73 cases with survey and registries and 35 with registries only. The main most frequent reasons for consultation were adequacy of therapeutic effort (46/42.6%), severe neurological involvement (15/13.9%), patient's quality of life (11/10.2%), patient-family-health system conflict (7/6.5%), and family's refusal of treatment (6/5.6%). High levels of satisfaction (> 95%) and moderate levels of feasibility (> 74%) and effectiveness (> 85%) were observed. In only 50/108 cases (46.3%), the consultation with the CEC was registered in the medical record, 44% of health care providers stated that the consultation had a positive impact on the patient and their family., Conclusions: Results helped to establish improvement opportunities, especially in terms of documentation and communication in the consultation process., Competing Interests: None, (Sociedad Argentina de Pediatría.)

- Abstract
Introduction: Cancer aggravates COVID-19 prognosis. Nosocomial transmission of SARS-CoV-2 is particularly frequent in cancer patients, who need to attend hospitals regularly. Since March 2020, all cancer patients having access to the Oncology Unit at the "Andrea Tortora" Hospital (Pagani, Salerno - referred to as "the Hospital") as inpatients or outpatients receiving intravenous therapy have been screened for SARS-CoV-2 using RT-PCR nasal swab. The ongoing COICA (COVID-19 infection in cancer patients) study is an ambispective, multicenter, observational study designed to assess the prognosis of SARS-CoV-2 infection in cancer patients. The aim of the study presented here was to explore potential differences in COVID-19-related outcomes among screening-detected versus nonscreening-detected SARS-CoV-2-infected patients. Methods: The COICA study enrolled cancer patients who had received any anticancer systemic therapy within 3 months since the day they tested positive for SARS-CoV-2 on RT-PCR. The target accrual is 128 patients, and the study was approved by the competent Ethics Committee. Only the subgroup of patients enrolled at the Hospital was considered in this unplanned interim analysis. Logistic regression analysis was used to evaluate the association of screening-based versus nonscreening-based diagnosis. Results: Since March 15, 2020, until August 15, 2021, a total of 931 outpatients and 230 inpatients were repeatedly screened for SARS-CoV-2 using RT-PCR nasal swab at the Hospital. Among these, 71 asymptomatic patients were positive on routine screening and 5 patients were positive for SARS-CoV-2 outside the institutional screening. Seven patients died because of COVID-19. At univariate analysis, nonscreening- versus screening-detected SARS-CoV-2 infection was associated with significantly higher odds of O
2 therapy (OR = 16.2; 95% CI = 2.2-117.1; p = 0.006), hospital admission (OR = 31.5; 95% CI = 3.1-317.8; p = 0.003), admission to ICU (OR = 23.0; 95% CI = 2.4-223.8; p = 0.007), and death (OR = 8.8; 95% CI = 1.2-65.5; p = 0.034). Conclusion: Routine screening with RT-PCR may represent a feasible and effective strategy in reducing viral circulation and possibly COVID-19 mortality in patients with active cancer having repeated access to hospital facilities., (© 2021 S.

- Abstract
Background: The COICA study is an ambispective, observational trial that was conceived to assess the clinical course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in cancer patients. A recently published, population-based, case-control study reported a reduced vaccine efficacy at 3-6 months in cancer patients compared to individuals without cancer. Objectives: The aim of the study was to describe coronavirus disease 19 (COVID-19) outcomes in cancer patients and analyze differences in SARS-CoV-2 outcomes between vaccinated and unvaccinated patients. Methods: Descriptive statistics and frequency counts were used to summarize characteristics of the study population. χ
2 test and the log-rank test were used to compare outcomes between vaccinated and unvaccinated patients. Results: A total of 141 cancer patients (80 males, 61 females) were recruited at two participating Institutions from March 2020 until April 2022 and observed from the time of positive SARS-CoV-2 test to the time of negativization or death. Approximately 35% of patients had been vaccinated at the time of infection with 2 (16 patients) or 3 (33 patients) vaccine doses. Vaccinated patients consistently and significantly showed improved COVID-19 outcomes compared to unvaccinated patients, with CT-diagnosed pneumonia, hospitalization, O2 therapy, and death reported in 0% versus 48.6%, 2.0% versus 15.2%, 0% versus 14.1%, and 0% versus 7.6%, respectively, of assessable patients ( p < 0.05). Vaccinated versus unvaccinated patients showed a significantly shorter time to negativization, with a median (95% confidence interval) time of 12 (10-14) versus 20 (17-23) days, respectively ( p < 0.001). Conclusions: Vaccination consistently improved all COVID-19 outcomes. No death was recorded among vaccinated patients. Additional research is especially warranted to establish optimal timing and patient selection for administration of the fourth vaccination dose., (© 2022 S. Karger AG, Basel.)- Published
