Abstract
BACKGROUND Immunotherapy combined with chemotherapy significantly improves progression-free survival compared to first-line chemotherapy alone in advanced endometrial cancer, with a much larger effect size in microsatellite-instability high (MSI-H) cases. New biomarkers might help to select patients that may have benefit among those with a microsatellite-stable (MSS) tumor. METHODS In a pre-planned translational analysis of the MITO END-3 trial, we assessed the significance of genomic abnormalities in patients randomized to standard carboplatin/paclitaxel without or with avelumab. RESULTS Out of 125 randomized patients, 109 had samples eligible for next-generation sequencing (NGS) analysis, and 102 had MSI tested. According to The Cancer Genome Atlas (TCGA), there were 29 cases MSI-H, 26 MSS TP53 wild-type (wt), 47 MSS TP53 mutated (mut), and one case with POLE mutation. Four mutated genes were present in more than 30% of cases: TP53, PIK3CA, ARID1A, and PTEN. Eleven patients (10%) had a BRCA1/2 mutation (five in MSI-H and six in MSS). High TMB (≥10 Muts/Mb) was observed in all MSI-H patients, in four out of 47 MSS/TP53 mut, and no case in the MSS/TP53 wt category. The effect of avelumab on progression-free survival significantly varied according to TCGA categories, being favorable in MSI-H and worst in MSS/TP53 mut (P interaction=0.003); a similar non-significant trend was seen in survival analysis. ARID1A and PTEN also showed a statistically significant interaction with treatment effect, which was better in the presence of the mutation (ARID1A P interaction=0.01; PTEN P interaction=0.002). CONCLUSION The MITO END-3 trial results suggest that TP53 mutation is associated with a poor effect of avelumab, while mutations of PTEN and ARID1A are related to a positive effect of the drug in patients with advanced endometrial cancer.

Abstract
In the clinical practice, it is not common for pediatricians to visit children with overgrowth phenotype. When it happens, it is important to focus on the age of manifestations and research the pathogenic causes using appropriate genetic test. Cowden syndrome is one of these rare causes; it is an autosomal dominant genodermatosis characterized by multiple hamartomas of ectodermal, mesodermal, and endodermal origin. It is caused by loss of function mutations in the phosphatase and tensin homolog (PTEN) gene located on chromosome 10q23.1 Loss of function of the PTEN gene contributes to overgrowth and risk for a variety of cancers including breast, thyroid, endometrium, skin, kidneys, and colon. The early diagnosis of Cowden disease allows a careful monitoring of the patients who are facing the risk of cancer transformation, which is the principal complication of the condition.

Abstract
OBJECTIVE In a previous study, we reported an increase of nasal nerve growth factor (NGF) in patients treated with high-pressure administration of sterile saline isotonic solution (HPpSIS). Herein we characterized the nasal mucosa in terms of innate immune response and cytokine signature, including antiviral properties. Potential NGF and antiviral benefits of HPpSIS were also discussed. PATIENTS AND METHODS Twenty (20) patients (11 males, 9 females; age range 30-75 years old) underwent HPpSIS and nasal samples were collected before and after treatment. Nasal scraping was used for morphological (smears and Quick May-Grunwald Giemsa staining, MGG), biochemical (Histamine, Serotonin; ELISA) and molecular (messenger RNA, mRNA) analyses. Amplification of transcripts specific for Toll-like receptor (TLR) 3 (TLR3), TLR7, TLR9, Interleukin-(IL) 18 (IL18), IL13, IL12, eosinophil-derived neurotoxin (EDN), Eosinophil Cationic Protein (ECP), γ Interferon (γIFN), tryptase and serotonin was performed using the 2-step real-time Reverse Transcription Polymerase Chain Reaction (RT-PCR). Clinical and laboratory data were analyzed and compared. RESULTS The clinical evaluation showed a protective effect of our therapy. Smears showed the presence of leucocytes, eosinophils (EOs) and mast cells (MCs), and increased immunoreactivity for ECP/RNase3 and EDN after HPpSIS. ELISA showed increased levels of Serotonin and EDN associated with unchanged levels of substance P(SP) and histamine. Increased eosinophil-derived neurotoxin eosinophil-derived neurotoxin (EDN) levels were confirmed by in situ fluorescent analysis. HPpSIS induced the upregulation of TLR3, TLR7 and TLR9 transcripts, while no changes were observed for Intercellular Adhesion Molecule 1 (ICAM1), IL18, Interleukin-15 (IL15) and IL12 transcripts nor for Interleukin-6 (IL6) and IL13. No changes were also observed for γIFN and EDN/RNase2 transcripts, while ECP/RNase3 transcripts were significantly upregulated after HPpSIS. Finally, tryptase transcripts were unchanged while serotonin transcripts were significantly increased after HPpSIS. CONCLUSIONS The clinical and biomolecular changes observed at the nasal mucosa due to HpSS treatment suggest the activation of an innate surveillance, by means of TLR transcription, and a possible anti-viral response due to EDN upregulation. It remains to be verified if NGF, known to be released locally upon HpSIS treatment, might in part be responsible for this local activation.

Abstract
Uterine cervical and endometrial cancers are two major gynecological malignancies, affecting women's health worldwide. Magnetic resonance imaging (MRI) is appropriate for evaluating malignant disease, thanks to the excellent soft tissue contrast and multiplanar imaging ability. Recently, functional MR techniques, namely diffusion-weighted imaging (DWI) and dynamic contrast-enhanced imaging (DCE), have proved to be a precious support not only in cancer diagnosis but also in disease staging, in the therapy planning, in monitoring response to treatment and during long-term recurrence surveillance. In the field of gynecologic oncology, the European Society of Urogenital Radiology (ESUR) recommends DWI and dynamic contrast-enhanced imaging (DCE-MRI) for local staging of endometrial and cervical cancer, but the potential application of functional imaging in all different aspects of patient management seems very promising. The aim of this article is to summarize the existing literature, providing a comprehensive update on the role of functional MRI in endometrial and cervical cancer.

Abstract
OBJECTIVE Osteoporosis is a chronic metabolic syndrome associated with debilitating consequences that represents one of the major non-communicable diseases and the most common bone illness that affects both men and women. This observational study evaluates the amount of physical activity and the nutritional intake in a group of postmenopausal women who have a sedentary job. PATIENTS AND METHODS All subjects underwent a medical evaluation, a body impedance analysis to evaluate body composition (fat mass, fat-free mass, and body cell mass), and a dual-energy X-ray absorptiometry to analyze bone mineral density. Additionally, a 3-day food record questionnaire and the International Physical Activity Questionnaire were administered respectively to evaluate patients' foods and beverages assumptions and the participants' Physical Activity levels. RESULTS The study showed that most of the patients had a moderate activity level and inadequate calcium and vitamin D assumption compared to guidelines. CONCLUSIONS The onset of osteoporosis seemed to be reduced at higher levels of leisure time, domestic, and transport activities, even in subjects who have a sedentary job and insufficient assumption of micronutrients.

Abstract
The scientific community has shown increasing interest in laser scribing for the direct fabrication of conductive graphene-based tracks on different substrates. This can enable novel routes for the noninvasive analysis of biofluids (such as sweat or other noninvasive matrices), whose results can provide the rapid evaluation of a person's health status. Here, we present a wearable sensing platform based on laser induced graphene (LIG) porous electrodes scribed on a flexible polyimide sheet, which samples sweat through a paper sampler. The device is fully laser manufactured and features a two layer design with LIG-based vertical interconnect accesses. A detailed characterization of the LIG electrodes including pore size, surface groups, surface area in comparison to electroactive surface area, and the reduction behavior of different LIG types was performed. The bare LIG electrodes can detect the electrochemical oxidation of both uric acid and tyrosine. Further modification of the surface of the LIG working electrode with an indoaniline derivative [4-((4-aminophenyl)imino)-2,6-dimethoxycyclohexa-2,5-dien-1-one] enables the voltammetric measurement of pH with an almost ideal sensitivity and without interference from other analytes. Finally, electrochemical impedance spectroscopy was used to measure the concentrations of ions through the analysis of the sweat impedance. The device was successfully tested in a real case scenario, worn on the skin during a sports session. In vitro tests proved the non-cytotoxic effect of the device on the A549 cell line.

Abstract
Background Standardized methods for reporting surgical quality have been described for all the major urological procedures apart from radical nephroureterectomy (RNU). Objective To propose a tetrafecta criterion for assessing the quality of RNU based on a consensus panel within the Young Association of Urology (YAU) Urothelial Group, and to test the impact of this tetrafecta in a multicenter, large contemporary cohort of patients treated with RNU for upper tract urothelial carcinoma (UTUC). Design, setting, and participants This was a retrospective analysis of 1765 patients with UTUC treated between 2000 and 2021. Outcome measurements and statistical analysis We interviewed the YAU Urothelial Group to propose and score a list of items to be included in the “RNU-fecta.” A ranking was generated for the criteria with the highest sum score. These criteria were applied to a large multicenter cohort of patients. Kaplan-Meier curves were built to evaluate differences in overall survival (OS) rates between groups, and a multivariable logistic regression model was used to find the predictors of achieving the RNU tetrafecta. Results and limitations The criteria with the highest score included three surgical items such as negative soft tissue surgical margins, bladder cuff excision, lymph node dissection according to guideline recommendations, and one oncological item defined by the absence of any recurrence in ≤12 mo. These items formed the RNU tetrafecta. Within a median follow-up of 30 mo, 52.6% of patients achieved the RNU tetrafecta. The 5-yr OS rates were significantly higher for patients achieving tetrafecta than for their counterparts (76% vs 51%). Younger age, lower body mass index, and robotic approach were found to be independent predictors of tetrafecta achievement. Conversely, a higher Eastern Cooperative Oncology Group score, higher clinical stage, and bladder cancer history were inversely associated with tetrafecta. Conclusions Herein, we present a “tetrafecta” composite endpoint that may serve as a potential tool to assess the overall quality of the RNU procedure. Pending external validation, this tool could allow a comparison between surgical series and may be useful for assessing the learning curve of the procedure as well as for evaluating the impact of new technologies in the field. Patient summary In this study, a tetrafecta criterion was developed for assessing the surgical quality of radical nephroureterectomy in patients with upper tract urothelial carcinoma. Patients who achieved tetrafecta had higher 5-yr overall survival rates than those who did not.

Abstract
OBJECTIVE Serotonin, which is a vasoactive amine, is an important neurotransmitter and is involved in many behavioral and psychological phenomena, such as pain, appetite, mood, and sleep. The primary purpose of our study was to investigate the effect of high-pressure administration of sterile physiological saline isotonic solution (HpPSIS) into nasal cavity and to determine the expression of the serotonin. PATIENTS AND METHODS The study was made in two branches, the previous with 14 volunteers, the subsequent study with 40 patients with mild anxiety disorder. The middle third of the inferior turbinate epithelial cells on the right nostril was scraped using a sterile curette and indicated as (pre), then, a spray of sterilized isotonic solution at high pressure on the left nostril was delivered, and 5 minutes later a similar stimulation was delivered on the same nostril. The stimulation was made with a specific spray dispenser. The middle third of the inferior turbinate epithelial cells on the left nostril was scraped using a sterile curette and indicated as (post). Then, based on the first part of our study, we started the second part and gave a treatment on forty new patients with anxiety disorder. RESULTS The results of these studies highlight the possibility of endogenous enhancement of serotonin by stimulation of mast cells. In the first part of the study, Serotonin significantly increased in protein extracts after treatment (64.35±5.33 vs. 10.97±2.17; unpaired two tailed t-test, t=9.8, df=24, p≤0.0001; F=6.035; DFn=12; DFd=12). In the second part of the study, in patients treated with HpPSIS, we observed improvement of mood, after one, two and three months, with a statistically significant reduction of DASS-21, while no reduction was observed in control patients, treated with normal pressure commercial spray. CONCLUSIONS This pilot study showed that the topical treatment of HpPHIS increases serotonin levels in nasal cavity. The observation reported in this study opens the way to a new valid strategy to enhance the level of endogenous serotonin. We observed a significant improvement of ASI on patients during HpPHIS therapy.

Abstract
Medicine has always tried to push the limits of life. The technological and scientific progress made in resuscitation now makes it possible to keep patients who are more and more severely affected alive, by compensating for organ failure. The management of the brain-damaged patient poses specific ethical problems in intensive care. Most in-hospital deaths of patients with severe acute brain injury occur after a decision to withhold or withdraw life-sustaining treatments. In these patients, a problem is the difficulty in predicting outcome at an early stage. Our reasoning in the management of brain-damaged patients in the intensive care is based on the four main principles of medical ethics: autonomy, beneficence, non-maleficence and distributive justice. In the case of a patient suffering from cerebral palsy, consent is most often impossible to obtain. The respect of this autonomy, can be done by means of advance directives or testimonies of the support person and family. Non-malficence in the resuscitated brain-damaged patient consists of avoiding unreasonable obstinacy. Medical futility means that the proposed therapy should not be performed because available data show that it will not improve the patient's medical condition. A determination of medical futility can be made either in the presence of a vanishingly small probability of physiological effect or an exceedingly poor quality of outcome. However, a distinction must be made between loss of autonomy and unreasonable obstinacy. French law specifies that the physician must use collegial procedure in situations that may concern a brain-damaged patient. In terms of ethical decision-making, the concept of "window of opportunity" is often mentioned. The temporal approach taken is the guarantee of an absence of "a rush". It is important for the health care team and the family to share the progress of the treatment so that everyone understands the evolution of what is happening and the risks taken for the patient. The resuscitation of the brain-damaged patient poses specific and difficult ethical problems. One of the challenges is to be able to assume our decisions, understand them and defend them. It is also to maintain the coherence of our actions and the cohesion of our teams necessary for the good care of our patients.

Abstract
OBJECTIVE This study aims to evaluate the effect of trans-resveratrol/carboxymethylated (1.3/1.6)-β-d-glucan administered via nasal, after FESS, assessing nasal respiratory distress and nasal mucosa healing. PATIENTS AND METHODS We enrolled 70 patients, from March 2019 to February 2020, with chronic nasal obstruction not responding to medical therapy and candidates to endoscopic nasal surgery. Patients were divided in two non-randomized groups: group A treated with trans-resveratrol/carboxymethylated (1.3/1.6)-β-d-glucan administered via nasal, and group B treated with 0.9% nasal irrigation saline. Patients were clinically evaluated, in post-operative period, at 7 (T0), 15 (T1), and 30 days (T2) with fibroendoscopy. The CRS (chronic rhinosinusitis) questionnaire (Snot 20) was administrated at T0, T1, and T2. The findings were scored with respect to middle turbinate edema. In both Groups, the inferior turbinate's medial aspect was scraped using a sterile disposable Rhino-probe mucosal curette (Arlington Scientific, Inc., Springville, UT, USA) at T0, T1, and T2. RESULTS Group A showed an improvement in Snot 20 in T1 and T2 both. The reduction of the mucosal edema and nasal secretion has been statistically significant in the Group A. A slight cell reduction was observed at T2 with respect to T1. This decreased pattern is more evident in nasal scraping from Group A. The appearance of epithelial cells at T2 of Group A is consistent with the reduction of inflammatory cells. CONCLUSIONS We can assert that in Group A it appears less evident the presence of edema, nasal congestion and crusts, resulting in a quick recover.

Abstract
Introduction Variable rate intravenous insulin infusion (VRIII) is a cornerstone treatment for controlling elevated blood glucose (BG) in inpatients who are missing meals, and/or have a critical illness. VRIII can cause serious harm to patients if used incorrectly. Traditional approaches to improving safety have focused on identifying errors, then finding solutions to prevent future recurrence. Such approaches fail to fully take into account the complex adaptive nature of healthcare systems, which cannot be controlled solely by standards or procedures. The Resilient Health Care (RHC) approach proposes that understanding the variability in healthcare practitioners’ everyday work e.g. a physical and cognitive activity directed toward achieving a specific goal, is key to enhancing patient safety (1). There are a considerable number of studies on using RHC to enhance safety, however, no studies to date have researched resilience in the use of VRIII. Aim This study sought to comprehensively understand, within a RHC framework, how VRIIIs are used in the clinical environment. Methods A qualitative observational study was conducted in a Vascular Surgery Unit. A purposive sample of two inpatients and all healthcare practitioners caring for VRIII aspects for these patients were recruited. The researcher video-recorded healthcare practitioners while prescribing, administering and monitoring VRIII. The video data were then transcribed and inductively coded to construct a deep understanding of the use of VRIII. A hierarchical task analysis (HTA) which is a core human factors approach (2) was used to represent the actual task for the use of VRIII. Results Twenty-two hours of video recordings of 10 healthcare practitioners were used to develop the final HTA with a top-level goal of controlling elevated BG using VRIII. The HTA clearly illustrated the complexity of using VRIIIs by highlighting more than 100 practical activities to achieve the goal. The observed challenges were mainly related to lack of knowledge e.g. the co-prescription of appropriate concurrent IV fluids, and system and technology problems e.g. the need for frequent BG monitoring. The analysis of the video data identified various strategies that healthcare practitioners used to respond to variability in work including knowledge, standardising practice e.g. the using of ready-to administer insulin infusions, and context-dependent adaptations including asking available colleagues to countersign administration and assigning the monitoring task to other staff when the nurses were busy. Most of the observed adaptations had positive outcomes in terms of patient care delivery. Conclusion This study was the first to have explored how ‘work is done’ in reference to the use of VRIII using HTA. The study was limited by time, the Covid-19 pandemic and number of participants. However, the developed HTA provided detailed tasks and, by highlighting when and how adaptations were used, systematically presented the process as it was actually done. Future work will focus on using the data from this study to model RHC in the use of VRIII in a way that allows the study site to better enhance patient safety. References 1.

Abstract
Suspensions of charged vesicles in water with added salt are widespread in nature and industrial production. Here we investigate, via Brownian dynamics simulations, a model that grasps the key features of these systems, with bidisperse colloidal beads interacting via a hard-core and an electrostatic double layer potential. Our goal is to focus on a set of interaction parameters that is not generic but measured in recent experiments, and relevant for a class of consumer products, such as liquid fabric softeners. On increasing the volume fraction in a range relevant to real formulation, we show that the dynamics become progressively slower and heterogeneous, displaying the typical signatures of an approaching glass transition. On lowering the salt concentration, which corresponds to increasing the strength and range of the electrostatic repulsion, the emergence of glassy dynamics becomes significantly steeper, and, remarkably, occurs at volume fractions well below the hard-sphere glass transition. The volume fraction dependence of the structural relaxation time at different salt concentration is well described through a functional law inspired by a recently proposed model (Krausser et al 2015 Proc. Natl Acad. Sci. USA 112 13762). According to our results, the investigated system may be thought of as a Wigner glass, i.e. a low-density glassy state stabilized by long-range repulsive interactions. Overall, our study suggests that glassy dynamics plays an important role in controlling the stability of these suspensions.

Abstract
PURPOSE To investigate critical aspects and effectiveness of in vivo dosimetry (IVD) tests obtained by an electronic portal imaging device (EPID) in a multicenter and multisystem context. MATERIALS AND METHODS Eight centers with three commercial systems-SoftDiso (SD, Best Medical Italy, Chianciano, Italy), Dosimetry Check (DC, Math Resolution, LCC), and PerFRACTION (PF, Sun Nuclear Corporation, SNC, Melbourne, FL)-collected IVD results for a total of 2002 patients and 32,276 tests. Data are summarized for IVD software, radiotherapy technique, and anatomical site. Every center reported the number of patients and tests analyzed, and the percentage of tests outside of the tolerance level (OTL%). OTL% was categorized as being due to incorrect patient setup, incorrect use of immobilization devices, incorrect dose computation, anatomical variations, and unknown causes. RESULTS The three systems use different approaches and customized alert indices, based on local protocols. For Volumetric Modulated Arc Therapy (VMAT) treatments OTL% mean values were up to 8.9% for SD, 18.0% for DC, and 16.0% for PF. Errors due to "anatomical variations" for head and neck were up to 9.0% for SD and DC and 8.0% for PF systems, while for abdomen and pelvis/prostate treatments were up to 9%, 17.0%, and 9.0% for SD, DC, and PF, respectively. The comparison among techniques gave 3% for Stereotactic Body Radiation Therapy, 7.0% (range 4.7-8.9%) for VMAT, 10.4% (range 7.0-12.2%) for Intensity Modulated Radiation Therapy, and 13.2% (range 8.8-21.0%) for 3D Conformal Radiation Therapy. CONCLUSION The results obtained with different IVD software and among centers were consistent and showed an acceptable homogeneity. EPID IVD was effective in intercepting important errors.

Abstract
OBJECTIVE This is a review on clinical presentation, diagnosis, and treatment of reported cases of Bickerstaff brain encephalitis. MATERIALS AND METHODS Cases of pediatric Bickerstaff's brainstem encephalitis collected from PubMed, Cochrane Library and Scopus Web of Science databases were reviewed. The inclusion criteria of the cases were based on age ≤ 18 years and the clinical characteristics of the disorder. RESULTS Twenty-seven articles on Bickerstaff's brainstem encephalitis, including 236 children from a total of 42 from January 1990 to January 2020, were selected. The phenotype of the pediatric cases confirmed those described in the previously published articles. Almost half of the cases demonstrated the positivity of anti-GQ1b antibody titers, but the antibodies' presence was not linked to longer healing time. However, it was found that individuals with neuroimaging changes needed a longer time to recovery. Overall, patients treated with any type of immunotherapy (intravenous immunoglobulins, steroid or plasmapheresis) demonstrated faster resolution of symptoms than supportive care. CONCLUSIONS Bickerstaff's brainstem encephalitis is an uncommon disorder, the short-term and long-term prognoses depend on the clinical presentation of the disorder, co-morbidity, instrumental investigations, and precocity of treatment.

Abstract
OBJECTIVE Primary headache disorders in children are one of the most prominent topics in the pediatric neurology literature. However, there are many unsolved aspects, including the conditions associated with migraine. The present study aims to report on the frequency of behavioral comorbidities in the setting of primary headache in childhood. PATIENTS AND METHODS In this study, we enlisted 475 children (290 males and 185 females; ratio 1.6:1), aged 4 to 14 years, who were affected by primary headache. In direct interviews, children and parents gave information on the association of their headache with, attention-deficit/hyperactivity disorder, learning disabilities, tics, anxiety, depression, and obsessive-compulsive disorder. Other 475 children with no history of headache or recognized neurological conditions were matched for age, sex, race, and socioeconomic status and were used as controls. RESULTS A significant association of primary headache was found with anxiety and depression (p-value <0.001); overall, behavioral disorders were more common in children who experienced headache than in controls (p-value <0.001). CONCLUSIONS Primary headache in children is not associated with most of the common behavioral conditions. On the contrary, there was a significant association with anxiety and depression, as reported in adults.

Abstract
Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal tumor originating from perivascular epitheloid cells showing melanocytic and smooth muscle differentiation. The uterus represents the second most common site of origin. A 49 years woman presented to our Hospital for a vaginal spontaneous expulsion of a mass suggestive for malignant mesenchymal tumor. The patient underwent total hysterectomy and bilateral salpingo-oophorectomy and the histopathological report was compliant with a PEComa with aggressive behavior. Medical Literature databases about PEComa were searched. The current literature identified near 90 cases of uterine PEComas and they are categorized as uncertain malignant potential or with aggressive behavior. Primary surgical excision represents the gold-standard treatment. Recently targeted therapy with mTOR inhibitors has been introduced with an important beneficial. In this paper we review the Literature about the uPEComa with aggressive behavior reporting the first case of spontaneous vaginal expulsion.

Abstract
Hypoxic-ischemic encephalopathy, also referred as HIE, is a type of brain injury or damage that is caused by a lack of oxygen to the brain during neonatal period. The incidence is approximately 1.5 cases per 1000 live births in developed countries. In low and middle-income countries, the incidence is much higher (10‒20 per 1000 live births). The treatment for neonatal HIE is hypothermia that is only partially effective (not more than 50% of the neonates treated achieve an improved outcome). HIE pathophysiology involves oxidative stress, mitochondrial energy production failure, glutaminergic excitotoxicity, and apoptosis. So, in the last years, many studies have focused on peptides that act somewhere in the pathway activated by severe anoxic injury leading to HIE. This review describes the pathophysiology of perinatal HIE and the mechanisms that could be the target of innovative HIE treatments.

Abstract
The response to strenuous exercise was investigated by reactive oxygen species (ROS) production, oxidative damage, thiol redox status, and inflammation assessments in 32 enrolled triathlon athletes (41.9 ± 7.9 yrs) during Ironman® (IR), or half Ironman® (HIR) competition. In biological samples, inflammatory cytokines, aminothiols (glutathione (GSH), homocysteine (Hcy), cysteine (Cys), and cysteinylglycine (CysGly)), creatinine and neopterin, oxidative stress (OxS) biomarkers (protein carbonyl (PC), thiobarbituric acid-reactive substances (TBARS)), and ROS were assessed. Thirteen HIR and fourteen IR athletes finished the race. Postrace, ROS (HIR +20%; IR +28%; p < 0.0001), TBARS (HIR +57%; IR +101%), PC (HIR +101%; IR +130%) and urinary neopterin (HIR +19%, IR +27%) significantly (range p < 0.05-0.0001) increased. Moreover, HIR showed an increase in total Cys +28%, while IR showed total aminothiols, Cys, Hcy, CysGly, and GSH increase by +48, +30, +58, and +158%, respectively (range p < 0.05-0.0001). ROS production was significantly correlated with TBARS and PC (R 2 = 0.38 and R 2 = 0.40; p < 0.0001) and aminothiols levels (range R 2 = 0.17-0.47; range p < 0.01-0.0001). In particular, ROS was directly correlated with the athletes' age (R 2 = 0.19; p < 0.05), with ultraendurance years of training (R 2 = 0.18; p < 0.05) and the days/week training activity (R 2 = 0.16; p < 0.05). Finally, the days/week training activity (hours/in the last 2 weeks) was found inversely correlated with the IL-6 postrace (R 2 = -0.21; p < 0.01). A strenuous performance, the Ironman® distance triathlon competition, alters the oxidant/antioxidant balance through a great OxS response that is directly correlated to the inflammatory parameters; furthermore, the obtained data suggest that an appropriate training time has to be selected in order to achieve the lowest ROS production and IL-6 concentration at the same time.

Abstract
OBJECTIVE Endometrial cancer (EC) is a complex gynecological neoplasm with several clinical, histopathological and genetic features. Different hormonal, metabolic and biochemical axes are involved in pathogenesis. Obesity is a well-known risk factor for this disease and the role of local and systemic effects of adipose tissue, especially in the promotion of subclinical chronic inflammation, is an important issue. Indeed, inflammation is related to the pathogenesis of different tumors, including EC. This review aims to remark the role of obesity and inflammation in the pathogenesis of EC cancer through an exploration of the current literature. MATERIALS AND METHODS We performed a comprehensive review of the literature through a PubMed search using key words and including English language papers looking at this topic. RESULTS Only few authors analyzed the role of inflammatory cytokines released by adipose tissue in visceral abdominal fat depots. Tumor Necrosis Factor-α, Interleukin-6, Interleukin-1 Receptor Antagonist, Nuclear Factor-kB, Leptin, Adiponectin and C Reactive Protein were studied for cancer risk prediction models, risk stratification or targeted therapies. Furthermore, genetic studies evaluated the effect of inflammatory cytokines secreted by visceral adipocytes in the modulation of angiogenesis and signaling pathways such as PI3K/AKT/mTOR, that result altered in the pathogenesis of EC. CONCLUSIONS The identification of inflammatory biomarkers released by adipose tissue, in the pathogenesis of EC, could be useful in improving diagnostic accuracy, identifying targets of therapy, suggesting useful lifestyle behaviors. A deeper knowledge of the genetic background of alterations in inflammatory pathway genes could better define the population exposed to a higher susceptibility to EC due to genetic polymorphisms. Future studies are needed to better understand this field.

Abstract
Mucus is a biomaterial with peculiar, gel-like viscoelastic properties, and bearing different functionalities, depending on the different mucosae it covers. It is clear that these functionalities have to stay effective throughout the in vivo broad range of physiological pH values at which the mucus is exposed. We sought here to determine the effect of pH on the rheological properties of ex vivo mucus. We demonstrate that viscoelastic properties of gastric mucus are quite "stable" to pH changes, in marked contrast with the pH sensitivity of purified mucin gels. We also find that the rheological features of porcine gastric mucus are reversible when the system is first alkalized up to solubilization (pH > 8.5) and then re-acidified to its initial pH value.

Abstract
Conjugation of small molecule agonists of Toll-like receptor 7 (TLR7) to proteins, lipids, or polymers is known to modulate potency, and the physical form or formulation of these conjugates is likely to have a major effect on their immunostimulatory activity. Here, we studied the effect of formulation on potency of a 1,2‑di‑(9Z‑octadecenoyl)‑sn‑glycero‑3‑phosphoethanolamine (DOPE) conjugated TLR7 agonist (DOPE-TLR7a) alongside assessing physical form using Dynamic Light Scattering (DLS), Nanosight Particle Tracking (NTA) analysis and Small Angle X-ray Scattering (SAXS). A very high potency of DOPE-TLR7a conjugate (EC50 around 9 nM) was observed either when prepared by direct dilution from DMSO or when formulated into 400-700 nm large multilamella liposomes containing dimethyldioctadecylammonium bromide salt (DDA) and DOPE. When prepared by dissolution in DMSO followed by dilution in aqueous culture medium, 93 ± 5 nm nanoparticles were formed. Without dilution from solution in DMSO, no nanoparticles were observed and no immunostimulatory activity could be detected without this formulation step. SAXS analysis of the conjugate after DMSO dissolution/water dilution revealed a lamellar order with a layer spacing of 68.7 Å, which correlates with arrangement in groups of 3 bilayers. The addition of another immunostimulatory glycolipid, trehalose‑6,6‑dibehenate (TDB), to DOPE:DDA liposomes gave no further increase in immunostimulatory activity beyond that provided by incorporating DOPE-TLR7a. Given the importance of nanoparticle or liposomal formulation for activity, we conclude that the major mechanism for increased potency when TLR7 agonists are conjugated to macromolecules is through alteration of physical form.

Abstract
Idiopathic intracranial hypertension (IIH) is a disorder of unknown origin, which is characterized by elevated intracranial pressure (ICP) without underlying etiological evidence of neurological disease. The purpose of the current study was to evaluate epidemiological features, clinical presentation, diagnostic findings and treatment of sixteen children (7 males and 9 females) with IIH. Medical records of the patients were obtained from the University Paediatric Hospital of Catania, Italy. Clinical features, investigations and treatment approaches were retrieved. The mean age of the sixteen children at onset of symptoms was 9 years (range: 4 to 16 years). Most of the patients were classified as pre-pubertal. Mean BMI was 28.9 kg/m2. In 93.75% of patients headache was the presenting clinical symptom; and in the same percentage papilledema was detected as the accompanied sign during diagnostic flow-chart. The mean lumbar puncture opening pressure (LPOP) was 350 mm H2O. Fifty percent of the cases had normal brain imaging, while 12.5% showed enlarged optic nerve diameter and one patient had an intraocular protrusion of the optic nerve on MRI. Two patients (12.5%) had venous sinus stenosis, and one case showed an abnormal spinal MRI. With regard to therapeutic approaches, 93.75% of the cases were successfully treated with Acetazolamide. None of the patients required surgical procedures, and all neuroimaging findings disappeared after receiving treatment. In the present study we investigated the association of IIH with venous sinus stenosis. We also found ocular ultrasound to be a useful non-invasive alternative method for determining papilledema in paediatric IIH, specifically in an emergency.

Abstract
We report a case of a 76-year-old man that referred to our hospital because of progressive mixed right hearing loss, aural fullness and pulsatile tinnitus synchronized with heart beats. Otoscopic examination revealed a reddish pulsatile mass beyond tympanic membrane. CT and MRI scans showed a class C glomus tumor. Anamnesis and a complete physical examination, with careful differential diagnosis, should be obtained to rule out highly vascularized middle ear lesion before any invasive procedure.

Abstract
In the present reply we show that the comments casting doubts on the results of our recent paper [M. De Corato et al., Phys. Rev. E 92, 053008 (2015)PLEEE81539-375510.1103/PhysRevE.92.053008] are based on a misinterpretation of the second-order fluid constitutive equation. Nevertheless, we show that, by considering alternative constitutive equations for the viscoelastic stress, we recover, to first-order in the Deborah number, the same results already obtained by De Corato et al. [Phys. Rev. E 92, 053008 (2015)PLEEE81539-375510.1103/PhysRevE.92.053008], thus dissipating any possible doubt about their validity.

Abstract
OBJECTIVE Carry out a preliminary study comparing postoperative pain and intraoperative and postoperative complications between micro-laparoscopy and laparoscopic monotrocart non-oncological adnexal surgery. METHODS All patients should benefit from a benign adnexal surgery were included prospectively from February to May 2014. The insufflation pressure, infiltration of trocar holes with a local anesthetic, postoperative analgesics were prescribed standardized. Operative and postoperative complications, type and length of hospital stay as well as EVA and analgesic consumption were recorded. RESULTS Nine patients were included in monotrocart group versus 7 in the micro-laparoscopy group. There were no differences in operative and postoperative complications, the type and length of hospital stay, as well as cosmetics satisfaction. However, there was a significant difference in the VAS to D2 (2.15 vs. 4.08, P=0.04) and analgesic consumption at D0 (P=0.04), D1 (P=0.04), D2 (P=0.02) and D3 (P=0.01), for the benefit of micro-laparoscopy. DISCUSSION AND CONCLUSION Despite an enrollment of patients low, micro-laparoscopy appears to have a significant advantage over the monotrocart laparoscopy for postoperative pain in benign adnexal surgery.

Abstract
BACKGROUND Assessing the risk of cytomegalovirus (CMV) viremia in kidney transplant recipients (KTR) may be helpful to indicate in which patient it is worth starting antiviral treatment during preemptive strategy. METHODS In 40 CMV-seropositive KTR preemptively treated with ganciclovir, we used interferon (IFN)-γ ELISpot test to evaluate whether monitoring T cells directed against phosphoprotein (pp) 65 and immediate early (IE)-1 antigens could predict the onset of viremia. RESULTS CMV viremia occurred in 24 patients (60%) within 120 days after transplantation. Non-viremic patients had higher anti-pp65, anti-IE-1 T cells, and estimated glomerular filtration rate (eGFR) in the first 90 days after transplantation. At logistic regression, anti-pp65, anti-IE-1 T cells, and eGFR measured at day 30 were significantly associated with CMV infection. Cutoff values of 15 spot-forming cells (SFCs)/200,000 peripheral blood mononuclear cells (PBMCs) for anti-IE, 40 SFCs/200,000 PBMCs for anti-pp65, and 46.6 mL/min/1.73 m(2) for eGFR, respectively, predicted the risk of CMV infection with high sensitivity and specificity (area under the receiver operating characteristic curve >0.75). Using a classification tree model, we identified as high-risk patients those showing anti-pp65 <42 SFCs/200,000 PBMCs and eGFR <62 mL/min/1.73 m(2) , as well as anti-pp65 ≥42 and anti-IE-1 <6.5 SFCs/200,000 PBMCs. CONCLUSION Monitoring CMV-specific T-cell responses and eGFR in the first month post transplant can identify patients at high risk of CMV infection, for whom preemptive antiviral therapy is recommended.
