Cognitive decline, a common consequence of aging, detrimentally affects independence, physical activity, and social interactions. This decline encompasses various cognitive functions, including processing speed, memory, language, and executive functioning. This trial aimed to investigate, with a double-blind, placebo-controlled clinical trial on 96 healthy older adults, the efficacy of once-daily 250 mg of a standardized grape (Vitis vinifera L.) juice extract (Cognigrape®) in improving short- and long-term cognitive functions. The results revealed significant improvements across multiple cognitive domains, notably immediate and delayed memory, visuospatial abilities, language, and attention, with improvements occurring within just 14 days, which continued to improve after 84 days of supplementation. The extract exhibited statistically significant enhancements in the Mini-Mental State Evaluation (MMSE), assessment of neuropsychological status (RBANS), “Esame Neuropsicologico Breve 2 (ENB-2), and Modified Bells Test (MBT) scores, with the latter test revealing a significant improvement in selective attention within just 90 min of the first dose. These positive results highlight the potential this natural grape extract has on improving cognitive function both acutely and chronically in a healthy aging population, which in turn supports a longer health span, at least cognitively.

Prostate cancer (PCa) is the third highest cause of cancer death in men. PCa is a very heterogeneous tumor form in terms of grade, phenotypes, and genetics, often accompanied by complex networks. PCa is characterized by slow growth that does not compromise the patient’s quality of life, unlike more aggressive forms showing rapid growth and progression. Early diagnosis, even for the most aggressive forms, increases the possibilities of cure with less aggressive treatments and fewer side effects. However, it is important to know how to decrease the exposure to modifiable risk factors, including diet, sedentary life, smoking and alcohol, can represent an effective tool to reduce the incidence of PCa. In addition, the chronic exposure to environmental factors, most of which act as endocrine disruptors, is the focus of recent studies for their potential role in promoting the onset and progression of PCa. Although molecular therapies and clinical trials for biomarker identification have been introduced into the management of PCa, these still lag behind research performed in other solid tumors. This review provides an overview of the modifiable factors of PCa, linked to lifestyle and environmental pollutants, which together with the development of new therapeutic targets, can reduce the incidence of PCa and improve the quality of life of patients.

Numerous animal models have demonstrated that caloric restriction (CR) is an excellent tool to delay aging and increase the quality of life, likely because it counteracts age-induced oxidative stress and inflammation. The aging process can affect the prostate in three ways: the onset of benign prostatic hyperplasia, prostatitis, and prostate cancer. In this study, we used 14 aged male Sprague Dawley rats, which were allocated into two groups, at the age of 18 months old. One group was fed ad libitum (a normal diet (ND)), and the other group followed a caloric restriction diet with a 60% decrease in intake. The rats were sacrificed at the age of 24 months. By immunohistochemical (IHC) and Western blot (WB) analyses, we studied the variations between the two groups in immune inflammation and fibrosis-related markers in aged prostate tissues. Morphological examinations showed lower levels of prostatic hyperplasia and fibrosis in the CR rats vs. the ND rats. The IHC results revealed that the prostates of the CR rats exhibited a lower immune proinflammatory infiltrate level and a reduced expression of the NLRP3 inflammasome pathway, together with significantly reduced expressions of mesenchymal markers and the profibrotic factor TGFβ1. Finally, by WB analysis, we observed a reduced expression of ERα, which is notoriously implicated in prostate stromal proliferation, and increased expressions of SOD1 and Hsp70, both exerting protective effects against oxidative stress. Overall, these data suggest that CR brings potential benefits to prostatic tissues as it reduces the physiological immune–inflammatory processes and the tissue remodeling caused by aging.

Partial nephrectomy (PN) is the primary surgical method for renal tumor treatment, typically involving clamping the renal artery during tumor removal, leading to warm ischemia and potential renal function impairment. Off-clamp approaches have been explored to mitigate organ damage, yet few results have emerged about the possible effects on hemoglobin loss. Most evidence comes from retrospective studies using propensity score matching, known to be sensitive to PS model misspecification. The energy balancing weights (EBW) method offers an alternative method to address bias by focusing on balancing all the characteristics of covariate distribution. We aimed to compare on- vs. off-clamp techniques in PN using EB-weighted retrospective patient data. Out of 333 consecutive PNs (275/58 on/off-clamp ratio), the EBW method achieved balanced variables, notably tumor anatomy and staging. No significant differences were observed in the operative endpoints between on- and off-clamp techniques, although off-clamp PNs showed slight reductions in hemoglobin loss and renal function decline, albeit with slightly higher perioperative blood loss. Our findings support previous evidence, indicating comparable surgical outcomes between standard and off-clamp procedures, with the EBW method proving effective in balancing baseline variables in observational studies comparing interventions.

Kidney transplantation is the best available renal replacement therapy for patients with end-stage kidney disease and is associated with better quality of life and patient survival compared with dialysis. However, despite the significant technical and pharmaceutical advances in this field, kidney transplant recipients are still characterized by reduced long-term graft survival. In fact, almost half of the patients lose their allograft after 15–20 years. Most of the conditions leading to graft loss are triggered by the activation of a large immune-inflammatory machinery. In this context, several inflammatory markers have been identified, and the deregulation of the inflammasome (NLRP3, NLRP1, NLRC4, AIM2), a multiprotein complex activated by either whole pathogens (including fungi, bacteria, and viruses) or host-derived molecules, seems to play a pivotal pathogenetic role. However, the biological mechanisms leading to inflammasome activation in patients developing post-transplant complications (including, ischemia-reperfusion injury, rejections, infections) are still largely unrecognized, and only a few research reports, reviewed in this manuscript, have addressed the association between abnormal activation of this pathway and the onset/development of major clinical effects. Finally, the regulation of the inflammasome machinery could represent in future a valuable therapeutic target in kidney transplantation.

Metabolic reprogramming is an emerging hallmark of cancer, involving the overexpression of metabolism-related proteins, such as glucose and monocarboxylate transporters and intracellular glycolytic enzymes. The biology of testicular germ cell tumors (TGCTs) is very complex, and although their metabolic profile has been scantily explored, some authors have recently reported that the metabolic rewiring of cancer cells resulted in an association with aggressive clinicopathological characteristics. In this study we have investigated, by immunohistochemical analysis, the expression of key proteins sustaining the hyperglycolytic phenotype in pure seminoma (SE, nr. 35), pure embryonal carcinoma (EC, nr. 17) tissues samples, and normal testes (nr. 5). GLUT1, CD44, PFK-1, MCT1, MCT4, LDH-A, and PDH resulted in more expression in EC cells compared to SE cells. TOM20 was more expressed in SE than in EC. GLUT1, MCT1, and MCT4 expression showed a statistically significant association with SE histology, while for EC, the association resulted in being significant only for GLUT1 and MCT4. Finally, we observed that EC resulted as negative for p53, suggesting that the GLUT1 and MTC overexpression observed in EC could be also attributed to p53 downregulation. In conclusion, our findings evidenced that EC exhibits a higher expression of markers of active aerobic glycolysis compared to SE, suggesting that the aggressive phenotype is associated with a higher glycolytic rate. These data corroborate the emerging evidence on the involvement of metabolic reprogramming in testicular malignancies as well, highlighting that the metabolic players should be explored in the future as promising therapeutic targets.

The therapeutic management of premature lifelong ejaculation (PE) ranges from behavioral therapy to pharmacological and surgical treatments. Hyaluronic Acid (HA) injection into the glans penis is a non-surgical procedure, intended to reduce glans hypersensitivity, improving the intravaginal ejaculation latency time (IELT). HA injection can be performed through different techniques that, although safe and effective, rarely can cause local complications. In this pilot uncontrolled study, we tested the effectiveness of a new technique based on a single HA injection into the frenulum of the glans, to improve IELT in a sample of patients affected by PE. We observed a significant increase of the IELT after one (median 73.3, IQR 66.2–79.9 s) and two months (66.2, 63.1–73.9) that gradually decreased at three months, remaining still significantly higher than at baseline (34.8, 30.9–37.4). PEDT and IIEF questionnaires significantly improved compared to baseline in the first two months of follow-up (p < 0.001). In conclusion, the preliminary results emerging from this pilot uncontrolled study, highlight the effectiveness of this one-shot HA injection approach, although a larger sample and longer follow-up time are needed to standardize the procedure.

Gut dysbiosis refers to an imbalance in gut microbiota composition and function. Opuntia ficus-indica extract has been shown to modulate gut microbiota by improving SCFA production in vivo and gastrointestinal discomfort (GD) in humans. The aim of this study was to demonstrate the efficacy of OdiliaTM on gastrointestinal health by changing the microbial diversity of species involved in inflammation, immunity, oxidation, and the brain–gut–muscle axis. A randomized, double-blind clinical trial was conducted in 80 adults with gut dysbiosis. The intervention consisted of a 300 mg daily intake of OdiliaTM (n = 40) or maltodextrin as a placebo (n = 40), administered for 8 weeks. Intervention effect was evaluated using 16S metagenomics and GIQLI/GSAS scores at baseline, at 4 and 8 weeks. Eight weeks of OdiliaTM supplementation positively modulates gut microbiota composition with a significant reduction in the Firmicutes to Bacteroidetes ratio (p = 0.0012). Relative abundances of beneficial bacteria (Bacteroides and Clostridium_XIVa) were significantly increased (p < 0.001), in contrast to a significant reduction in pro-inflammatory bacteria (p < 0.001). Accordingly, GIQLI and GSAS scores revealed successful improvement in GD. OdiliaTM may represent an effective and well-tolerated treatment in subjects with gut dysbiosis.

Cancer has been described as a risk factor for greater susceptibility to SARS-CoV-2 infection and severe COVID-19, mainly for patients with metastatic disease. Conversely, to that reported for most solid and hematological malignancies, the few available clinical studies reported that the infection did not increase the risk of death in renal cancer patients. The expression on proximal tubular renal cells of the key players in cellular viral uptake, ACE2, TMPRSS2, and NRP1, seems to be the mechanism for the direct kidney injury seen in patients with COVID-19. Interestingly, data from The Cancer Genome Atlas and experimental analyses on various renal cancer cell lines demonstrated that the above-reported receptors/cofactors are maintained by renal cancer cells. However, whether SARS-CoV-2 infection directly kills renal cancer cells or generates enhanced immunogenicity is a question worth investigating. In addition, some researchers have further addressed the topic by studying the expression and prognostic significance of gene signatures related to SARS-CoV-2 infection in renal cancer patients. The emerging data highlights the importance of better understanding the existence of a link between renal cancer and COVID-19 since it could lead to the identification of new prognostic factors and the development of new therapeutic targets in the management of renal cancer patients.

Alpha-lipoic acid (ALA) is a natural antioxidant dithiol compound, exerting antiproliferative and antimetastatic effects in various cancer cell lines. In our study, we demonstrated that ALA reduces the cell growth of prostate cancer cells LNCaP and DU-145. Western blot results revealed that in both cancer cells, ALA, by upregulating pmTOR expression, reduced the protein content of two autophagy initiation markers, Beclin-1 and MAPLC3. Concomitantly, MTT assays showed that chloroquine (CQ) exposure, a well-known autophagy inhibitor, reduced cells’ viability. This was more evident for treatment using the combination ALA + CQ, suggesting that ALA can reduce cells’ viability by inhibiting autophagy. In addition, in DU-145 cells we observed that ALA affected the oxidative/redox balance system by deregulating the KEAP1/Nrf2/p62 signaling pathway. ALA decreased ROS production, SOD1 and GSTP1 protein expression, and significantly reduced the cytosolic and nuclear content of the transcription factor Nrf2, concomitantly downregulating p62, suggesting that ALA disrupted p62-Nrf2 feedback loop. Conversely, in LNCaP cells, ALA exposure upregulated both SOD1 and p62 protein expression, but did not affect the KEAP1/Nrf2/p62 signaling pathway. In addition, wound-healing, Western blot, and immunofluorescence assays evidenced that ALA significantly reduced the motility of LNCaP and DU-145 cells and downregulated the protein expression of TGFβ1 and vimentin and the deposition of fibronectin. Finally, a soft agar assay revealed that ALA decreased the colony formation of both the prostate cancer cells by affecting the anchorage independent growth. Collectively, our in vitro evidence demonstrated that in prostate cancer cells, ALA reduces cell growth and counteracts both migration and invasion. Further studies are needed in order to achieve a better understanding of the underlined molecular mechanisms.

When treating structured health-system-related knowledge, the establishment of an over-dimension to guide the separation of entities becomes essential. This is consistent with the information retrieval processes aimed at defining a coherent and dynamic way – meaning by that the multilevel integration of medical textual inputs and computational interpretation – to replicate the flow of data inserted in the clinical records. This study presents a strategic technique to categorize the clinical entities related to patients affected by neurodegenerative diseases. After a pre-processing range of tasks over paper-based and handwritten medical records, and through subsequent machine learning and, more specifically, natural language processing operations over the digitized clinical records, the research activity provides a semantic support system to detect the main symptoms and locate them in the appropriate clusters. Finally, the supervision of the experts proved to be essential in the correspondence sequence configuration aimed at providing an automatic reading of the clinical records according to the clinical data that is needed to predict the detection of neurodegenerative disease symptoms.

One of the major goals in the advancement of basic cancer research focuses on the development of new anticancer therapies. To understand the molecular mechanisms of cancer progression, acquired drug resistance, and the metastatic process, the use of preclinical in vitro models that faithfully summarize the properties of the tumor in patients is still a necessity. The tumor is represented by a diverse group of cell clones, and in recent years, to reproduce in vitro preclinical tumor models, monolayer cell cultures have been supplanted by patient-derived xenograft (PDX) models and cultured organoids derived from the patient (PDO). These models have proved indispensable for the study of the tumor microenvironment (TME) and its interaction with tumor cells. Prostate cancer (PCa) is the most common neoplasia in men in the world. It is characterized by genomic instability and resistance to conventional therapies. Despite recent advances in diagnosis and treatment, PCa remains a leading cause of cancer death. Here, we review the studies of the last 10 years as the number of papers is growing very fast in the field. We also discuss the discovered limitations and the new challenges in using the organoid culture system and in using PDXs in studying the prostate cancer phenotype, performing drug testing, and developing anticancer molecular therapies.

Caloric restriction is an effective intervention to protract healthspan and lifespan in several animal models from yeast to primates, including humans. Caloric restriction has been found to induce cardiometabolic adaptations associated with improved health and to delay the onset and progression of kidney disease in different species, particularly in rodent models. In both aging and obesity, fibrosis is a hallmark of kidney disease, and epithelial–mesenchymal transition is a key process that leads to fibrosis and renal dysfunction during aging. In this study, we used an aged and obese rat model to evaluate the effect of long-term (6 months) caloric restriction (−40%) on renal damage both from a structural and functional point of view. Renal interstitial fibrosis was analyzed by histological techniques, whereas effects on mesenchymal (N-cadherin, Vimentin, Desmin and α-SMA), antioxidant (SOD1, SOD2, Catalase and GSTP1) inflammatory (YM1 and iNOS) markers and apoptotic/cell cycle (BAX, BCL2, pJNK, Caspase 3 and p27) pathways were investigated using Western blot analysis. Our results clearly showed that caloric restriction promotes cell cycle division and reduces apoptotic injury and fibrosis phenotype through inflammation attenuation and leukocyte infiltration. In conclusion, we highlight the beneficial effects of caloric restriction to preserve elderly kidney function.

Nod-like receptor protein 3 (NLRP3) is a multi-protein complex belonging to the innate immune system, whose activation by danger stimuli promotes inflammatory cell death. Evidence supports the crucial role of NLRP3 inflammasome activation in the transition of acute kidney injury to Chronic Kidney Disease (CKD), by promoting both inflammation and fibrotic processes. Variants of NLRP3 pathway-related genes, such as NLRP3 itself and CARD8, have been associated with susceptibility to different autoimmune and inflammatory diseases. In this study, we investigated for the first time the association of functional variants of NLRP3 pathway-related genes (NLRP3-rs10754558, CARD8-rs2043211), with a susceptibility to CKD. A cohort of kidney transplant recipients, dialysis and CKD stage 3–5 patients (303 cases) and a cohort of elderly controls (85 subjects) were genotyped for the variants of interest and compared by using logistic regression analyses. Our analysis showed a significantly higher G allele frequency of the NLRP3 variant (67.3%) and T allele of the CARD8 variant (70.8%) among cases, compared with the control sample (35.9 and 31.2%, respectively). Logistic regressions showed significant associations (p < 0.001) between NLRP3 and CARD8 variants and cases. Our results suggest that the NLRP3 rs10754558 and CARD8 rs2043211 variants could be associated with a susceptibility to CKD.

Many studies have suggested that SARS-CoV-2, directly or indirectly, can affect the male reproductive system, although the underlined mechanisms have not been completely elucidated yet. The purpose of this review is to provide a summary of the current data concerning the impact of SARS-CoV-2 infection on the male urogenital tract, with a particular emphasis on the testes and male fertility. The main data regarding the morphological alterations in the testes emerged from autoptic studies that revealed interstitial congestion, micro thrombosis, reduction of Sertoli, Leydig, and germinal cells, infiltrated immune cells, and atrophic seminiferous tubules consistent with orchitis. Furthermore, men with severe infection exhibit sperm parameter alterations, together with abnormalities of the hypothalamic–pituitary–testis axis, strongly suggesting that SARS-CoV-2 could increase the risk of male infertility. However, despite the inadequate number of longitudinal studies, spermatogenesis and sex hormone imbalance seem to improve after infection resolution. The yet unresolved question is whether the virus acts in a direct or/and indirect manner, as discordant data related to its presence in the testis and semen have been reported. Regardless of the direct effect, it has been postulated that the cytokine storm and the related local and systemic inflammation could strongly contribute to the onset of testis dysfunction, leading to male infertility. Therefore, multicentric and longitudinal studies involving a large number of patients are needed to understand the real impact of SARS-CoV-2 infection on male reproduction.

Recent and growing literature has reported that oleuropein (OLE), the main polyphenol in olive leaf extract, inhibits tumor cell proliferation and reduces the invasiveness properties of cancer cells; therefore, OLE may play a significant role in the development of new drugs for cancer treatment. These antineoplastic properties have been reported in many experimental cancer models, but the effect of OLE on seminoma cells is yet to be evaluated. In the present study, we demonstrate, for the first time, that OLE reduces cell viability in both intra- and extragonadal TCAM-2 and SEM-1 seminoma cells, respectively, in a dose-dependent manner. As shown by Western-blot analysis, OLE exposure reduced cyclin-D1 expression and upregulated p21Cip/WAF1, concomitantly affecting the upstream pathway of NF-κB, leading to the reduction of its nuclear content, thereby suggesting that OLE could modulate cell-cycle regulators by inhibiting NF-κB. Moreover, Annexin V staining revealed that OLE induced apoptosis in cancer cells and upregulated the pro-apoptotic factor BAX. Through wound-healing scratch and transmigration assays, we also demonstrated that OLE significantly reduced the migration and motility of TCAM-2 and SEM-1 cells, and downregulated the expression of TGFβ-1, which is known to be the main pro-fibrotic factor involved in the acquisition of the migratory and invasive properties of cancer cells. Collectively, our results indicate that OLE reduces seminoma cell proliferation, promotes apoptosis, and counteracts cell migration and motility. Further studies are needed to explore the molecular mechanisms underlying these observed effects.

Several studies have demonstrated that the p75NTR low-affinity receptor of Nerve Growth Factor (NGF), is produced in abnormally large amounts in several human cancer types. However, the role of p75NTR varies substantially depending on cell context, so that a dual role of this receptor protein in tumor cell survival and invasion, as well as cell death, has been supported in recent studies. Herein we explored for the first time the expression of p75NTR in human specimens (nr = 40) from testicular germ cell tumors (TGCTs), mostly seminomas. Nuclear overexpression of p75NTR was detected by immunohistochemistry in seminoma tissue as compared to normal tissue, whereas neither NGF nor its high-affinity TrkA receptor was detected. An increased nuclear staining of phospho-JNK, belonging to the p75NTR signaling pathway and its pro-apoptotic target gene, p53, was concomitantly observed. Interestingly, our analysis revealed that decreased expression frequency of p75NTR, p-JNK and p53 was related to staging progression, thus suggesting that p75NTR may represent a specific marker for seminoma and staging in TGCTs.

Medicine ,Science - Abstract
Nerve growth factor is a neurotrophin that promotes cell growth, differentiation, survival and death through two different receptors: TrkA(NTR) and p75(NTR). Nerve growth factor serum concentrations increase during many inflammatory and autoimmune diseases, glomerulonephritis, chronic kidney disease, end-stage renal disease and, particularly, in renal transplant. Considering that nerve growth factor exerts beneficial effects in the treatment of major central and peripheral neurodegenerative diseases, skin and corneal ulcers, we asked whether nerve growth factor could also exert a role in Cyclosporine A-induced graft nephrotoxicity. Our hypothesis was raised from basic evidence indicating that Cyclosporine A-inhibition of calcineurin-NFAT pathway increases nerve growth factor expression levels. Therefore, we investigated the involvement of nerve growth factor and its receptors in the damage exerted by Cyclosporine A in tubular renal cells, HK-2. Our results showed that in HK-2 cells combined treatment with Cyclosporine A + nerve growth factor induced a significant reduction in cell vitality concomitant with a down-regulation of Cyclin D1 and up-regulation of p21 levels respect to cells treated with Cyclosporine A alone. Moreover functional experiments showed that the co-treatment significantly up-regulated human p21promoter activity by involvement of the Sp1 transcription factor, whose nuclear content was negatively regulated by activated NFATc1. In addition we observed that the combined exposure to Cyclosporine A + nerve growth factor promoted an up-regulation of p75 (NTR) and its target genes, p53 and BAD leading to the activation of intrinsic apoptosis. Finally, the chemical inhibition of p75(NTR) down-regulated the intrinsic apoptotic signal. We describe two new mechanisms by which nerve growth factor promotes growth arrest and apoptosis in tubular renal cells exposed to Cyclosporine A.

PurposeThe aim of this study is a semantic comparative analysis between the current pandemic and the Spanish flu. It is based on a bilingual terminological perspective oriented to evaluate and compare the terms used to describe and communicate the pandemic's issues both to biomedical experts and to a non-specialist public.Design/methodology/approachThe analysis carried out is a terminological comparative investigation performed on two corpora, the first containing scientific English articles, the second Italian national newspapers' issues on two pandemics, the Spanish flu and the current Covid-19 disease, towards the detection of semantic similarities and differences among them through the implementation of computational tasks and corpus linguistics methodologies.FindingsGiven the cross-fielding representativeness of terms, and their relevance within specific historical eras, our study is conducted both on a synchronic and on a diachronic level to discover the common lexical usages in the dissemination of the pandemic issues.Originality/valueThe study presents the extraction of the main representative terms about two pandemics and their usages to share news about their trends among the population and the integration of a topic modeling detection procedure to discover some of the main categories representing the lexicon of the pandemics with reference to a list of classes created by external thesauri and ontologies on pandemics. As a result, a detailed overview of the discrepancies, as well as similarities, retrieved in two historical corpora dealing with a common subject, i.e. the pandemics' terminology, is provided.

The nucleotide-binding domain, leucine-rich containing family, pyrin domain-containing-3 (NLRP3) inflammasome, a multiprotein complex belonging to the innate immune system, plays a key role in the chronic inflammatory response, through the production of proinflammatory cytokines, IL-1β and IL-18, which can elicit their effects through receptor activation, both locally and systemically. Furthermore, it has been demonstrated the interaction of NLRP3 inflammasome components with redox signaling, endoplasmic reticulum stress, and mitochondrial function. A growing literature reported the involvement of NLRP3 platform dysregulation in the pathophysiology of different chronic diseases so it has been proposed that the inhibition of NLRP3 inflammasome could represent a new potential therapeutic target in the management of autoimmune and chronic inflammatory diseases, including cancer. In addition, it has been demonstrated that Sars-CoV2 preferentially activates NLRP3 inflammasome, strongly contributing to the hyperinflammatory state responsible for COVID-19. Recently, in vitro and animal models of both infectious and non-infectious male genital tract diseases affecting fertility, demonstrated the activation of the innate immune system, leading to increased levels of pro-inflammatory cytokines, as well as apoptosis and pyroptosis and that it was likely mediated by activation of the NLRP3 inflammasome. The objective of this review was to analyze the evidence on the role and the mechanisms by which NLRP3-inflammasome pathway activation may exert detrimental effects on the male reproductive system. Furthermore, although the literature data are still discordant, this review also highlighted the possible connection between SARS-CoV-2 infection/NLRP3 activation/oxidative stress and male infertility.

BackgroundPolypharmacy is prevalent in long-term care homes (LTCH) and increases the risk of adverse drug events. Feasible and effective deprescribing interventions applicable in the LTCH environment are needed. MethodsWe performed a mixed methods study to evaluate the feasi-bility, applicability, and effectiveness of an electronic depre-scribing tool, MedSafer, to facilitate quarterly medication reviews (QMRs) on two pilot units in an academic long-term care home (LTCH). Chart reviews collected resident health data. The prevalence of deprescribing at a standard QMR was compared with a QMR conducted three months later with MedSafer. Feedback from physicians on their experience with MedSafer was obtained through semi-structured interviews. ResultsPhysicians found MedSafer helpful in guiding deprescribing decisions and suggested software improvements to increase the feasibility in LTCH. The average number of medications deprescribed per resident was significantly higher at the Med-Safer QMR (mean reduction = 1.1 medications, SD = 1.3) compared to the standard QMR (mean reduction = 0.5, SD = 0.9) (absolute difference of 0.5; SD 1.1; p = .02). ConclusionMedSafer has the potential to increase deprescribing in LTCHs by flagging potentially inappropriate medications. Integration in the electronic medical record might increase uptake in LTCHs. Further research should investigate the generalizability of MedSafer in a larger population and in non-academic LTCHs.

Objectives: Current guidelines suggest that patients with severe dementia on cholinesterase inhibitors (CHEIs) should discontinue their CHEIs by taper. This study aims to define the prevalence of patients admitted to a palliative care unit (PCU) with dementia on a CHEI and to determine whether these patients were tapered off their CHEIs according to current deprescribing guidelines. Design: This is a descriptive retrospective chart review that examined patients admitted to a PCU with dementia on a CHEI from January 2015 to June 2019. Methods: Individuals admitted to the PCU with a primary or comorbid diagnosis of dementia were identified. Their corresponding CHEI dose, frequency and discontinuation pattern were identified. Data were analyzed using descriptive statistics. Results: A total of 36 patients were admitted to the PCU with dementia on a CHEI (prevalence of 2.3%). The median length of stay was 21 days. For 31 of these patients, their CHEI was discontinued, only 9 of which had a taper. Of the 24 patients who discontinued their CHEI suddenly, 10 patients had an order to discontinue their CHEI in the last 2 days before their date of death. Conclusion: This study suggests that although patients admitted to a PCU with dementia have their CHEI discontinued, the discontinuation was done without a taper. In many cases the CHEIs were continued through the active stage of dying. Future work should explore reasons why PCU physicians are mostly late to taper CHEIs for patients admitted with dementia.

Transplantation ,Nephrology - Abstract
BACKGROUND AND AIMS Peritoneal dialysis (PD) is a renal replacement therapy that allows the elimination of metabolic waste products and excess body fluid through the peritoneal membrane. The exposure to PD solution contributes to membrane aging and fibrosis resulting in ultrafiltration and clearance failure. The glucose, used as an osmotic factor, in PD dialysate triggers several processes involved in the pathogenesis of peritoneal fibrosis, angiogenesis and epithelial to mesenchymal transition. Studies on natural extracts, such as Oleuropein (Ole), a powerful antioxidant with remarkable antifibrotic and protective effects on the peritoneal membrane, are currently being validated. This study aims to develop a method based on multi-photon microscopy to study the physiology of the peritoneal membrane during dialysis exchange and to validate in vivo the effects of the Ole in animal models of fibrosis undergoing dialysis treatment. METHOD Multi-photon microscopy allows in vivo evaluation of the microcirculation that supply the peritoneum and also to study the framework of mesothelial cells and their underlying layer of collagen fibers that contributes to the sub-mesothelial space. We have implemented the surgical procedure in order to optimize the stability of a flap of parietal peritoneum to directly observe at the scope. With this approach the peritoneal membrane is evaluable at baseline condition and during exposure to dialysate solutions. RESULTS Our method allows building a three-dimensional render of the peritoneal membrane, with the evaluation of all the single layers without the use of specific markers. In this way we could assess specifically the phenomena induced by the fibrotic process: the thickening of the sub-mesothelial interstitium and the greater density of the vascular network. Furthermore, in vivo measurements of flow in the vessels of microcirculation (arterioles, capillaries, post-capillary venules) determine that exposure to hypotonic solutions increases significantly the flow in large-diameter vessels due to better permeability and hemodilution. Finally in order to evaluate the possibility to detect morphological and functional changes in pathogenic model we have used the well-established model of peritoneal fibrosis derived by 15 days’ long exposure of the peritoneal membrane with 3.86% glucose dialysate. Whth this approach we could detect the significant increase in the parameters of cellularity, vascularization, fibrosis and thickening of collagen fibers. In order to test the sensibility of our approach to the evaluation of the peritoneal membrane senescence parameters, we tested the effect of Ole in preventing the damage induced by high glucose–containing dialysate. Ole reduced both the thickness and the organization of the collagen fibers and the vascular network, including the number of branch points. CONCLUSION The developed method has potential for a dynamic and reliable in vivo approach. Studies are ongoing to validate the effects of drugs and dialysates with different osmotic and electrolytic compositions on the dialysis capacities of the peritoneal membrane and on the blood flow in peritoneal capillaries. This method offers great potential for testing new pharmacological approaches aimed at preserving the structural and functional integrity of the peritoneum and for the validation of substances, such as natural extracts with beneficial effects against the damage induced in the long term by conventional dialysis solutions.

General Medicine - Abstract
Introduction: Breaking bad news to patients and families can be challenging for healthcare providers. The present study conducted a systematic review of the literature to determine if formal communication training using the SPIKES protocol improves learner satisfaction, knowledge, performance, or system outcomes. Method: MEDLINE, Embase, CINAHL Plus (Nursing & Allied Health Sciences), and PsycINFO Databases were searched with keywords BAD NEWS and SPIKES. Studies were required to have an intervention using the SPIKES model and an outcome that addressed at least one of the four domains of the Kirkpatrick model for evaluating training effectiveness. The Cochrane Risk of Bias Tool was used to conduct a risk of bias assessment. Due to heterogeneity in the interventions and outcomes, meta-analysis was not undertaken and instead, a narrative synthesis was used with the information provided in the tables to summarise the main findings of the included studies. Results: Of 622 studies screened, 37 publications met the inclusion criteria. Interventions ranged from the use of didactic lecture, role play with standardised patients (SPs), video use, debriefing sessions, and computer simulations. Evaluation tools ranged from pre and post intervention questionnaires, OSCE performance with rating by independent raters and SPs, and reflective essay writing. Conclusions: Our systematic review demonstrated that the SPIKES protocol is associated with improved learner satisfaction, knowledge and performance. None of the studies in our review examined system outcomes. As such, further educational development and research is needed to evaluate the impact of patient outcomes, including the optimal components and length of intervention.

Background The activation of NLRP3 inflammasome machinery has a central role in obesity-induced inflammation. Genetic studies well support the involvement of functional variants of NLRP3 and its negative regulator, CARD8, in the pathogenesis of complex diseases with an inflammatory background. We have investigated the influence of NLRP3 (rs4612666; rs10754558) and CARD8 (rs204321) genetic variants in both the inflammatory status of visceral adipose tissue (VAT) from patients with severe obesity and in the systemic oxidative stress before and after sleeve-gastrectomy (SLG). Methods Twenty-three consecutive severe obese patients candidate to SLG were enrolled in the study. Visceral adipose tissue (VAT) biopsies, obtained during SLG, were used to evaluate the expression of NLRP3, IL-1β, IL-6, and MCP-1 by real-time RT-PCR. DNA was extracted from peripheral blood lymphocytes and genotyped by RFLP analysis. Before and 3 months after SLG, all patients underwent the assessment of oxidative stress, biochemical parameters, and body composition as measured by bioelectrical impedance analysis (BIA). Results Increased expression of NLRP3, IL-6, IL-1β, and MCP-1 mRNA was observed in VAT of rs4612666 C variant carriers, in which higher oxidative stress was also detected as compared to non-carrier individuals. In all patients, oxidative stress, biochemical and BIA parameters improved after SLG, regardless of genotype. No significant correlations were found with the other genetic variants. Conclusions Our results suggest that the NLRP3 rs4612666 C variant may promote a worse pro-inflammatory milieu and higher oxidative stress, thus leading patients to a more severe obesity phenotype. A larger study is needed to confirm this assumption and to investigate the impact of the NLRP3 rs4612666 C variant on severe obesity.

Reducing human-microbial encounters through improved infection prevention and control (IPC) is widely acknowledged to be critical for reducing the emergence, transmission and burden of antimicrobial resistance (AMR). However, despite its centrality in the Global Action Plan (GAP) on AMR and adoption as a goal in National Action Plans around the world, there has been limited progress on reducing the incidence of antimicrobial resistant infections globally. In this paper, we argue that closer attention to different faces of AMR could propel progress in this area, with a focus on bedridden people situated in liminal spaces in the Thai health system and suburban economy. Our ethnographic fieldwork followed the cases of 16 bedridden people through the eyes of their carers and medical staff. We 'descended into the ordinary' to encounter individuals living - and dying - in the shadows of the labour-intensive suburbs of Bangkok. Here, AMR and IPC protocols are operationalised in the context of competing priorities and pragmatic decision-making. Focussing on three ethnographic vignettes, we use the analytic frames of precarity and care to consider how particular (bedridden) bodies are differentially exposed to AMR infections in the context of economic, social, and political arrangements that structure embodied vulnerabilities and forms and foci of care. Whilst the political work of calculating the burden of AMR may be oriented around galvanising support through a sense of magnitude and generalised risk, this research serves as a reminder that the faces of AMR include those who disproportionately shoulder the global burden of AMR, making it at once exceptional and ordinary.

Most of the common drugs used to treat the cervical cancer, which main etiological factor is the HPV infection, cause side effects and intrinsic/acquired resistance to chemotherapy. In this study we investigated whether an olive leaf extract (OLE), rich in polyphenols, was able to exert anti-tumor effects in human cervical cancer cells (HeLa). MTT assay results showed a reduction of HeLa cells viability OLE-induced, concomitantly with a gene and protein down-regulation of Cyclin-D1 and an up-regulation of p21, triggering intrinsic apoptosis. OLE reduced NFkB nuclear translocation, which constitutive activation, stimulated by HPV-oncoproteins, promotes cancer progression and functional studies revealed that OLE activated p21Cip/WAF1 in a transcriptional-dependent-manner, by reducing the nuclear recruitment of NFkB on its responsive elements. Furthermore, OLE treatment counteracted epithelial-to-mesenchymal-transition and inhibited anchorage-dependent and -independent cell growth EGF-induced. Finally, MTT assay results revealed that OLE plus Cisplatin strengthened the reduction of cells viability Cisplatin-induced, as OLE inhibited NFkB, AkT and MAPK pathways, all involved in Cisplatin chemoresistance. In conclusion, we demonstrated that in HeLa cells OLE exerts pro-apoptotic effects, elucidating the molecular mechanism and that OLE could mitigate Cisplatin chemoresistance. Further studies are needed to explore the potential coadiuvant use of OLE for cervical cancer treatment.

Several studies have demonstrated that the p75NTR low-affinity receptor of Nerve Growth Factor (NGF), is produced in abnormally large amounts in several human cancer types. However, the role of p75NTR varies substantially depending on cell context, so that a dual role of this receptor protein in tumor cell survival and invasion, as well as cell death, has been supported in recent studies. Herein we explored for the first time the expression of p75NTR in human specimens (nr = 40) from testicular germ cell tumors (TGCTs), mostly seminomas. Nuclear overexpression of p75NTR was detected by immunohistochemistry in seminoma tissue as compared to normal tissue, whereas neither NGF nor its high-affinity TrkA receptor was detected. An increased nuclear staining of phospho-JNK, belonging to the p75NTR signaling pathway and its pro-apoptotic target gene, p53, was concomitantly observed. Interestingly, our analysis revealed that decreased expression frequency of p75NTR, p-JNK and p53 was related to staging progression, thus suggesting that p75NTR may represent a specific marker for seminoma and staging in TGCTs.

The mammalian target of rapamycin inhibitor (mTOR-I) Rapamycin, a drug widely used in kidney transplantation, exerts important anti-cancer effects, particularly in Kaposi's Sarcoma (KS), through several biological interactions. In this in vivo and in vitro study, we explored whether the activation of the autophagic pathway through the low-affinity receptor for nerve growth factor, p75NTR , may have a pivotal role in the anti-cancer effect exerted by Rapamycin in S. Our Kimmunohistochemistry results revealed a significant hyper-activation of the autophagic pathway in KS lesions. In vitro experiments on KS cell lines showed that Rapamycin exposure reduced cell viability by increasing the autophagic process, in the absence of apoptosis, through the transcriptional activation of p75NTR via EGR1. Interestingly, p75NTR gene silencing prevented the increase of the autophagic process and the reduction of cell viability. Moreover, p75NTR activation promoted the upregulation of phosphatase and tensin homolog (PTEN), a tumour suppressor that modulates the PI3K/Akt/mTOR pathway. In conclusion, our in vitro data demonstrated, for the first time, that in Kaposi's sarcoma, autophagy triggered by Rapamycin through p75NTR represented a major mechanism by which mTOR inhibitors may induce tumour regression. Additionally, it suggested that p75NTR protein analysis could be proposed as a new potential biomarker to predict response to Rapamycin in kidney transplant recipients affected by Kaposi's sarcoma.

Background: Visiting restrictions placed on palliative care units due to the COVID-19 pandemic have resulted in emotional and psychological distress to patients, their caregivers and families. However, the informational needs of caregivers during pandemic visiting restrictions have never been studied. Aim: To identify the informational needs of caregivers of patients admitted to an end-of-life palliative care unit under COVID-19 visiting restrictions. Methods: Nineteen caregivers of patients admitted to a single palliative care unit while under pandemic visiting restrictions were recruited. A cross-sectional telephone survey was performed, which examined the importance of different informational needs of caregivers and how well these needs were being met. Results: Receiving information about hospital regulations/procedures, health updates about the patient, social support for the patient and how to communicate with the patient in light of visitor restrictions were 'very important' to caregivers. In contrast, caregivers were 'neutral' towards receiving information about accessing psychosocial/emotional support for the caregiver and religious/spiritual support for the patient. Qualitative data summaries provided a richer understanding of these quantitative rankings. Conclusion: These findings will assist healthcare professionals in providing optimal informational support to caregivers during visitor restrictions in order to improve the growing psychological impact on this population.

Cardiovascular diseases are the main cause of mortality in the Western population, so the attempt to find a marker capable of predicting their early onset is not surprising. It is known that arteriogenic erectile dysfunction (ED) precedes the onset of a major coronary event by several years. However, a marker that is able to early identify those patients who should undergo further diagnostic investigations is, to date, missing. Recent research on this topic has focused on the role of the mean platelet volume (MPV), a marker of platelet activity that is high in most vascular diseases, such as coronary artery disease (CAD), stroke, peripheral artery disease (PAD), and ED. The basic pathophysiological mechanism of all these clinical conditions is atherosclerosis. Platelets play a central role in amplifying this process both indirectly by stimulating endothelial cells to produce inflammatory cytokines and chemokines, and directly through the expression of membrane receptors and the release of molecules that contribute to the formation of atherosclerotic plaque. The objective of this review is to critically analyze the evidence on the role of MPV in predicting the diagnosis and severity of vasculogenic ED and the possibility of using this simple marker as a first step to start a diagnostic process aimed at assessing the cardiovascular risk in these patients.

The Italian Law 38/2010, 'Dispositions to guarantee access to Palliative Care and Pain Management' orders that the health care systems of Italian regions create dedicated structures for palliative care and pain therapies, according to a specific organizational model called 'Hub-Spoke', to ensure the diagnostic-therapeutic continuity of patients affected by chronic pain (CP). The aim of our study was to investigate the Italian pain therapy network, 8 years following the approval of the Law. We sent a questionnaire to the national health representatives operating in CP management. The main result emerging from the analysis concerns the management of mini-invasive procedures, showing that 93.2% of the responding facilities carry out invasive procedures, 6.8% do not perform them and that 100% of the facilities belonging to 12 regions provided these procedures, while in eight regions more than 80%. Finally, only 38.5% of facilities declared to have a shared protocol with the relevant territorial facilities in order to guarantee the process of care and assistance of patients affected by CP. In conclusion, our study demonstrated the efficacy of the organizational model in most of the responding facilities, although the territorial management of patients after their hospital discharge should be strengthened.

ObjectivePalliative care plays an essential role in enhancing the quality of life and quality of death for residents in long-term care homes (LTCHs). Access to palliative care specialists is one barrier to providing palliative care to LTCHs. This project focused on palliative telemedicine, specifically evaluating whether integration of early palliative care specialist consultation into an LTCH would be feasible through the implementation of videoconferencing during routine interdisciplinary care conferences.MethodThis was a mixed-methods evaluation of a pilot program implementation over 6 months, to integrate early palliative care into an LTCH. There were two pilot communities with a total of 61 residents. Resident demographics were collected by a chart review, and palliative telemedicine feasibility was evaluated using staff and family member surveys.ResultsFor the 61 residents, the average age of the residents was 87 years, with 61% being female and 69% having dementia as the primary diagnosis. The mean CHESS (Change in Health, End-Stage Disease, Signs, and Symptoms) and ADL (Activities of Daily Living) scores were 0.8 and 4.0, respectively, with 54% having a Palliative Performance Scale score of 40. Seventeen clinical staff surveys on palliative teleconferences were completed with the majority rating their experience as high. Ten out of the 20 family members completed the palliative teleconference surveys, and the majority were generally satisfied with the experience and were willing to use it again. Clinical staff confidence in delivering palliative care through telemedicine significantly increased (P = 0.0021).Significance of resultsThe results support the feasibility of videoconferencing as a means of palliative care provision. Despite technical issues, most clinical staff and families were satisfied with the videoconference and were willing to use it again. Early integration of palliative care specialist services into an LTCH through videoconferencing also led to improved self-rated confidence in the palliative approach to care by clinical staff.

Patients with kidney transplantation often have a worse quality of life than the general population. One of the reasons for this, in male patients, is the high prevalence of erectile dysfunction. This is mainly due to the presence of comorbidities, surgery for kidney transplantation, adverse drug effects, psychological changes related to chronic disease, as well as hyperprolactinemia and hypogonadism. Whenever these endocrine dysfunctions occur after kidney transplantation, they must be corrected with appropriate treatment, i.e., testosterone replacement therapy. Administration of the phosphodiesterase-5 inhibitor (PDE5i) sildenafil at the recommended posology does not significantly alter the pharmacokinetics of the calcineurin inhibitors cyclosporin A or tacrolimus and does not impair kidney allograft function. Tacrolimus increases the peak concentration and prolongs the half-life of PDE5i in kidney transplant patients and, therefore, daily administration cannot be recommended due to the significant drop in blood pressure. Intracavernous injection or topical application of alprostadil can be a second-line option for the treatment of erectile dysfunction after kidney transplantation, which does not alter cyclosporine concentrations and does not deteriorate kidney function. Finally, penile prostheses can be successfully implanted following pelvic organ transplantation after eliminating the risk of infection associated with surgery.

The mesothelial cells (MCs) play an important role in the morpho-functional alterations of the peritoneal membrane (PM) undergoing peritoneal dialysis (PD). MCs, through the epithelial-mesenchymal transition process (EMT), progressively acquire a myofibroblast-like phenotype, promoting peritoneal fibrosis (PF) and failure of peritoneal membrane function. Transforming growth factor β1 (TGFβ1), through canonical and non-canonical pathways, promotes the epithelial-mesenchymal transition (EMT) process leading to PF. To investigate the therapeutic potential of an olive leaf extract (OLE) on preserving peritoneal membrane function, we evaluated the effect of OLE on the TGFβ1-induced EMT in mesothelial cells, Met5A, and elucidated the underlying molecular mechanisms. As assessed by changes in the expression of epithelial, mesenchymal, and fibrotic cell markers (such as E-cadherin, N-cadherin, α-SMA, fibronectin, vimentin), levels of matrix metalloproteinases (MMP2 and MMP9), and cell migration, OLE inhibited the TGFβ1-induced EMT. Importantly, the beneficial effect of OLE was mediated by reduction of the TGFβ1-induced activation of Smad2/3 signaling and the mitigation of extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38 mitogen-activated protein kinase (MAPK) phosphorylation. Smad/non-Smad signaling pathways, activated by TGFβ1, both reduce expression of epithelial marker E-cadherin which has a crucial role in EMT initiation. Interestingly, we observed that in presence of OLE activity of the E-cadherin, promoter was increased and concomitantly OLE reduced the nuclear content of its co-repressor SNAIL. Our results suggest the potential therapeutic of OLE to counteract fibrotic process in peritoneal dialysis patients.

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive enlargement of kidney cysts, leading to chronic kidney disease. Since the available treatment for ADPKD is limited, there is emerging interest for natural compounds as potential therapeutic candidates. The aim of our study was to investigate whether an olive leaf extract may be able to counteract the cyst growth in an in vitro model of ADPKD. We treated WT9-12 cells with an olive leaf extract (OLE). In monolayer culture we evaluated cell viability by the MTT assay, protein expression by western-blot analysis and apoptosis by DNA laddering and TUNEL assays. For functional studies we used transient transfection and ChIP assays. Intracellular calcium measurement was performed with a spectrofluorimeter using a fluorescent probe. 3D-cell-culture was used for cyst growth studies. OLE reduced the WT9-12 cell growth rate and affected intracellular signaling due to high c-AMP levels, as OLE reduced PKA levels, enhanced p-AKT, restored B-Raf-inactivation and down-regulated p-ERK. We elucidated the molecular mechanism by which OLE, via Sp1, transactivates the p21WAF1/Cip1 promoter, whose levels are down-regulated by mutated PKD1. We demonstrated that p-AKT up-regulation also played a crucial role in the OLE-induced anti-apoptotic effect and that OLE ameliorated intracellular calcium levels, the primary cause of ADPKD. Finally, using a 3D-cell-culture model we observed that OLE reduced the cyst size. Therefore, multifaceted OLE may be considered a new therapeutic approach for ADPKD treatment.

Several studies have demonstrated that the p75NTR low-affinity receptor of Nerve Growth Factor (NGF), is produced in abnormally large amounts in several human cancer types. However, the role of p75NTR varies substantially depending on cell context, so that a dual role of this receptor protein in tumor cell survival and invasion, as well as cell death, has been supported in recent studies. Herein we explored for the first time the expression of p75NTR in human specimens (nr = 40) from testicular germ cell tumors (TGCTs), mostly seminomas. Nuclear overexpression of p75NTR was detected by immunohistochemistry in seminoma tissue as compared to normal tissue, whereas neither NGF nor its high-affinity TrkA receptor was detected. An increased nuclear staining of phospho-JNK, belonging to the p75NTR signaling pathway and its pro-apoptotic target gene, p53, was concomitantly observed. Interestingly, our analysis revealed that decreased expression frequency of p75NTR, p-JNK and p53 was related to staging progression, thus suggesting that p75NTR may represent a specific marker for seminoma and staging in TGCTs.

I prophylaxis is the most effective strategy to eradicate I deficiency disorders, but it has been shown to affect the thyroid disease pattern. In this study, we assessed the frequency of thyroid disorders in an adult population living in two areas of southern Italy after implementing I prophylaxis. To this aim, a cross-sectional, population-based study including 489 subjects from an I-deficient rural and an I-sufficient urban area of southern Italy was conducted. Thyroid ultrasound was performed on all participants, and urine and blood samples were collected from each subject. The levels of thyroid-stimulating hormone (TSH), thyroglobulin (TgAb) and thyroperoxidase antibodies (TPOAb), urinary I excretion (UIE), and thyroid volume and echogenicity were evaluated. We found that the median UIE was higher in the urban than in the rural area (P=0·004), whereas the prevalence of subjects affected by goitre was higher in the rural compared with the urban area (P=0·003). Positive TgAb rather than TPOAb were more frequent in subjects from the urban area compared with the rural area (P=0·009). The hypoechoic pattern at thyroid ultrasound (HT-US) was similar between the two areas, but TgAb were significantly higher (P=0·01) in HT-US subjects from the urban area. The frequency of elevated TSH did not differ between the two screened populations, and no changes were found for TgAb positivity in subjects with high TSH in the urban compared with the rural area. Our findings support that the small risks of I supplementation are far outweighed by the substantial benefits of correcting I deficiency, although continued monitoring of populations is necessary.

Background: Palliative care is often initiated late for patients with end stage liver disease (ESLD) with pain being a common morbidity that is under-treated throughout the disease trajectory. When admitted to a palliative care unit (PCU), nurses play a pivotal role and must be highly informed to ensure effective pain management. The aim of this study is to determine the baseline level of knowledge and attitudes of PCU nurses regarding pain management in patients with ESLD. Methods: A descriptive, cross-sectional self-administered survey design was used for this study. The sample comprised 35 PCU nurses working at a continuing chronic care facility in Toronto, Ontario, Canada. Data on the knowledge and attitudes of the nurses regarding pain management in patients with ESLD, was obtained using a modified version of the “Nurses Knowledge and Attitudes Survey Regarding Pain” (NKASRP) tool. Results: Thirty-one PCU nurses were included for the analysis, giving a response rate of 89%. The mean total percentage score for the nurses on the modified version of the NKASRP was 72%. Only 26% of the nurse participants obtained a passing score of 80% or greater. There were no significant differences in mean total scores by age, gender, years of nursing experience or education level. Conclusions: The findings of this study provide important information about the inadequate knowledge and attitude in nurses regarding pain management for patients with ESLD. It is suggested that targeted educational programs and quality improvement initiatives in pain management for patients with ESLD could improve knowledge and attitudes for PCU nurses.

Recent epidemiological studies suggest an increase of sexual and reproductive chronic diseases caused by problematic behaviours acquired during peri-pubertal age. The aims of our study were: (i) to investigate awareness of sexual transmitted infections (STIs) among adolescents, (ii) to describe the close relationship between possibly incorrect lifestyles during adolescence and reproductive and sexual disturbances during adulthood. The &ldquo, Amico-Andrologo&rdquo, survey is a permanent nationwide surveillance program supported by the Italian Ministry of Health. We administered a validated structured interview to investigate the lifestyle of adolescents and their knowledge of STIs. We selected a cohort of 360 male high-school students aged &ge, 18 years old. In this cohort, 150 (41.5%) were smokers while 59 (19.7%) smoked more than 10 cigarettes/day, 25 (9.3%) declared a consumption &ge, 6 drinks/weekend, and 65 (19.7%) were habitual cannabis consumers (at least twice/week). Among the sample of students selected, the main sources of sexual disease information were the internet and friends. The perceived level of knowledge on STIs was the same between students that used contraceptive methods and students that did not. The present results demonstrate that adolescents in Calabria do not receive appropriate information about risky health behaviours. Therefore, there is a necessity for specific educational programs to increase awareness of dangerous behaviours during the transitional age that is relevant for a safe sexual and reproductive adult life.
