A Design Thinking Approach for Museum Institutions

In these recent years, museum institutions are facing challenges such as deepening diversity among audiences and within the workforce, shifting authority and keeping pace with the creation of a digital offering to be provided in the new shared economy. Additionally, museums cannot just deliver knowledge as information anymore. They are forced to seek to be relevant and meaningful for the audiences and the society. Thus, a visitor-centered approach needs to be developed. The design thinking framework can help museum professionals to face the challenges they handle in today’s world. Indeed, this approach is focused on people and not on a specific product or service. The goal is to understand the needs of customers, their wishes and, based on this information, find the best solution to respond to the type of problem identified or the strategy to be developed. For this reason, the ratio of this discipline provides that people are stimulated to find alternative, creative, and innovative solutions designed and built on the reality of the facts and not dictated by instinct. The aim of this chapter is to investigate the characteristics of the design thinking approach and to analyze if this framework is suitable for museum institutions

The Impact of Exogenous Shocks on Business Models and Business Relationships: An Empirical Analysis of the Italian Music Industry

Purpose: Scholars have been increasingly interested in understanding business models. However, little attention has been paid to how business models change in reaction to exogenous circumstances and how business relationships alter be-cause of business model changes. This paper investigates how the business model paradigm of the Italian music industry altered in response to two major exogenous influences that impacted the sector: the digital revolution and the COVID-19 pandemic. Design/methodology/approach: As the purpose of this study is to investigate phenomena in a real-world setting, qualitative research methodology has been selected as the most appropriate one. It was decided to conduct sixteen semi-structured interviews with professionals active in the Italian music business, selected through a combination of snowball and convenience sampling. Findings: The empirical findings indicate that the digital revolution and COVID-19 pushed Italian music companies to revise their business models by either reducing or adding the number of linkages to the existing ones. This was done in order for the companies to remain competitive in an environment that is constantly changing and to outcompete rivals. Originality/value: Few studies have evaluated how business relationships alter in response to the many business models emerging in the music industry due to external causes. This research is one of the first to examine music companies’ reactions to exogenous events such as crises or disruptive advances that affect the competitive landscap

Central Sensitization in the Bladder Pain Syndrome

Introduction: Nociceptive hyper-excitability and Central Sensitization (CS), have been identified as responsible for maintaining pain in several chronic neuropathic pain conditions, among which Bladder pain syndrome (BPS). Aim of the present study was to evaluate in patients with BPS the correlation between CS and the following items pain duration, the number of other CS related diseases, the number of tried treatments for pain and of diagnostic investigations before the proper diagnosis and to identify the cut-off value of the pain delays for predicting the worsening of sensitization. Method: Fifty-eight consecutively BPS outpatients were recruited from 2014 to 2016. They were submitted to Central Sensitization Inventory (CSI), Overactive Bladder Questionnaire (OAB-8v) and visual analogic scale (VAS) for pain. We used a descriptive analysis (mean, standard deviation, range) and Spearman and Kendall test coefficient as correlation index. One-way ANOVA test was used for the comparison between groups. P-value less than 0.05 were required for statistical significance. We used receiver operating characteristic (ROC) curve analysis to retrospectively analyze the association between the years of the disease and pathological values o of CSI. Results: The patients were observed after 13.1 + 11.0 years by the onset of The CSI score was 69.7+15.8. Resulting significantly lower in patients with BPS onset in the last year the correlation between CSI and the disease duration was significant. The number of previous investigations was 3.7 + 2.8while the number of previous treatments for chronic pain was 5.9 + 3.1, resulting significantly related to CSI score. The OAB-8v was 21 + 7.5 (range 2-34). The worsening of the symptoms related to the overactive bladder at OAB-8v was related to a greater CS. After 1,5 years of the onset of the pain the CS show a progressive worsening. The mean number of other diseases (fibromyalgia, irritable bowel syndrome, anxiety or depression, migraine, neck injury, Panic Disorder Attack, chronic fatigue syndrome, temporomandibular joint syndrome, restless leg syndrome, multiple chemical sensitivities) associated to CS was 2.8+1.9. The correlation between the number of diseases associated to CS and the years of disease resulted significant. Conclusion: Patients with long lasting pelvic pain show high levels of CS, and other central sensitivity syndromes (CSS) together to worsening of overactive bladder symptoms, and increasing number of used drugs. The delay of diagnosis is related to a greater sensitization process

Modulated structures in electroconvection in nematic liquid crystals

Motivated by experiments in electroconvection in nematic liquid crystals with homeotropic alignment we study the coupled amplitude equations describing the formation of a stationary roll pattern in the presence of a weakly-damped mode that breaks isotropy. The equations can be generalized to describe the planarly aligned case if the orienting effect of the boundaries is small, which can be achieved by a destabilizing magnetic field. The slow mode represents the in-plane director at the center of the cell. The simplest uniform states are normal rolls which may undergo a pitchfork bifurcation to abnormal rolls with a misaligned in-plane director.We present a new class of defect-free solutions with spatial modulations perpendicular to the rolls. In a parameter range where the zig-zag instability is not relevant these solutions are stable attractors, as observed in experiments. We also present two-dimensionally modulated states with and without defects which result from the destabilization of the one-dimensionally modulated structures. Finally, for no (or very small) damping, and away from the rotationally symmetric case, we find static chevrons made up of a periodic arrangement of defect chains (or bands of defects) separating homogeneous regions of oblique rolls with very small amplitude. These states may provide a model for a class of poorly understood stationary structures observed in various highly-conducting materials ("prechevrons" or "broad domains").Comment: 13 pages, 13 figure

Risk of Severe Non AIDS Events Is Increased among Patients Unable to Increase their CD4+ T-Cell Counts >200+/μl Despite Effective HAART

Immunological non-response (INR) despite virological suppression is associated with AIDS-defining events/death (ADE). Little is known about its association with serious non-AIDS-defining events (nADE)

Use of efavirenz or atazanavir/ritonavir is associated with better clinical outcomes of HAART compared to other protease inhibitors: routine evidence from the Italian MASTER Cohort.

Randomized trials and observational cohorts reported higher rates of virological suppression after highly active antiretroviral therapy (HAART) including efavirenz (EFV), compared with boosted protease inhibitors (PIs). Correlations with immunological and clinical outcomes are unclear. Patients of the Italian MASTER cohort who started HAART from 2000 to 2010 were selected. Outstanding outcome (composite outcome for success (COS)) was introduced. We evaluated predictors of COS (no AIDS plus CD4+ count >500/ mm3 plus HIV-RNA <500 copies/mL) and of eight single outcomes either at month 6 or at year 3. Multivariable logistic regression was conducted. There were 6259 patients selected. Patients on EFV (43%) were younger, had greater CD4+ count, presented with AIDS less frequently, and more were Italians. At year 3, 90% of patients had HIV RNA <500 copies/mL, but only 41.4% were prescribed EFV, vs. 34.1% prescribed boosted PIs achieved COS (p <0.0001). At multivariable analysis, patients on lopinavir/ritonavir had an odds ratio of 0.70 for COS at year 3 (p <0.0001). Foreign origin and positive hepatitis C virus-Ab were independently associated with worse outcome (OR 0.54, p <0.0001 and OR 0.70, p 0.01, respectively). Patients on boosted PIs developed AIDS more frequently either at month 6 (13.8% vs. 7.6%, p <0.0001) or at year 3 (17.1% vs. 13.8%, p <0.0001). At year 3, deaths of patients starting EFV were 3%, vs. 5% on boosted PIs (p 0.008). In this study, naïve patients on EFV performed better than those on boosted PIs after adjustment for imbalances at baseline. Even when virological control is achieved, COS is relatively rare. Hepatitis C virus-positive patients and those of foreign origin are at risk of not obtaining COS.

Circulating sCD14 Is Associated with Virological Response to Pegylated-Interferon-Alpha/Ribavirin Treatment in HIV/HCV Co-Infected Patients

Microbial translocation (MT) through the gut accounts for immune activation and CD4+ loss in HIV and may influence HCV disease progression in HIV/HCV co-infection. We asked whether increased MT and immune activation may hamper anti-HCV response in HIV/HCV patients.98 HIV/HCV patients who received pegylated-alpha-interferon (peg-INF-alpha)/ribavirin were retrospectively analyzed. Baseline MT (lipopolysaccharide, LPS), host response to MT (sCD14), CD38+HLA-DR+CD4+/CD8+, HCV genotype, severity of liver disease were assessed according to Early Virological Response (EVR: HCV-RNA <50 IU/mL at week 12 of therapy or ≥2 log(10) reduction from baseline after 12 weeks of therapy) and Sustained Virological Response (SVR: HCV-RNA <50 IU/mL 24 weeks after end of therapy). Mann-Whitney/Chi-square test and Pearson's correlation were used. Multivariable regression was performed to determine factors associated with EVR/SVR.71 patients displayed EVR; 41 SVR. Patients with HCV genotypes 1-4 and cirrhosis presented a trend to higher sCD14, compared to patients with genotypes 2-3 (p = 0.053) and no cirrhosis (p = 0.052). EVR and SVR patients showed lower levels of circulating sCD14 (p = 0.0001, p = 0.026, respectively), but similar T-cell activation compared to Non-EVR (Null Responders, NR) and Non-SVR (N-SVR) subjects. sCD14 resulted the main predictive factor of EVR (0.145 for each sCD14 unit more, 95%CI 0.031-0.688, p = 0.015). SVR was associated only with HCV genotypes 2-3 (AOR 0.022 for genotypes 1-4 vs 2-3, 95%CI 0.001-0.469, p = 0.014).In HIV/HCV patients sCD14 correlates with the severity of liver disease and predicts early response to peg-INF-alpha/ribavirin, suggesting MT-driven immune activation as pathway of HIV/HCV co-infection and response to therapy

30-Day morbidity and mortality of bariatric metabolic surgery in adolescence during the COVID-19 pandemic – The GENEVA study

Background: Metabolic and bariatric surgery (MBS) is an effective treatment for adolescents with severe obesity. Objectives: This study examined the safety of MBS in adolescents during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This was a global, multicentre and observational cohort study of MBS performed between May 01, 2020, and October 10,2020, in 68 centres from 24 countries. Data collection included in-hospital and 30-day COVID-19 and surgery-specific morbidity/mortality. Results: One hundred and seventy adolescent patients (mean age: 17.75 ± 1.30 years), mostly females (n = 122, 71.8%), underwent MBS during the study period. The mean pre-operative weight and body mass index were 122.16 ± 15.92 kg and 43.7 ± 7.11 kg/m2, respectively. Although majority of patients had pre-operative testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (n = 146; 85.9%), only 42.4% (n = 72) of the patients were asked to self-isolate pre-operatively. Two patients developed symptomatic SARS-CoV-2 infection post-operatively (1.2%). The overall complication rate was 5.3% (n = 9). There was no mortality in this cohort. Conclusions: MBS in adolescents with obesity is safe during the COVID-19 pandemic when performed within the context of local precautionary procedures (such as pre-operative testing). The 30-day morbidity rates were similar to those reported pre-pandemic. These data will help facilitate the safe re-introduction of MBS services for this group of patients
