Vision-related quality of life and symptom perception change over time in newly-diagnosed primary open angle glaucoma patients.
To evaluate the change over time of vision-related quality of life (QoL) and glaucoma symptoms in a population of newly-diagnosed primary open angle glaucoma (POAG) patients. Multicenter, prospective study. Consecutive newly-diagnosed POAG patients were enrolled and followed-up for one year. Follow-up visits were scheduled at 6 and 12 months from baseline. At each visit, vision-related QoL and glaucoma-related symptoms were assessed by the means of the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) and the Glaucoma Symptom Scale (GSS), respectively. Trends over time for NEI-VFQ-25 and GSS scores were evaluated with longitudinal linear mixed models. One-hundred seventy-eight patients were included in the analysis. At baseline, early to moderate glaucoma stages were associated with higher scores for most GSS and NEI-VFQ-25 items, while lower best-corrected visual acuity was associated with lower scores for 4 of the 12 NEI-VFQ-25 items. During the follow-up, all the GSS scores, the NEI-VFQ-25 total score, and 7 of the 12 NEI-VFQ-25 scores significantly improved (p < 0.05). In multivariate model, higher increases of most GSS and NEI-VFQ-25 scores were modeled in patients with low scores at baseline. Vision-related QoL and glaucoma-related symptom perception significantly improved during the one-year follow-up in this population of newly diagnosed POAG patients
Dynamic tests and modal identification of Corso Grosseto viaduct decks before the dismounting
This paper describes the dynamic test campaign carried out on four prestressed concrete decks being part of the viaduct of Corso Grosseto in Turin, before its demolition after a service life of 50 years. Subsequently, 25 beams, 4 box girders and 2 pier caps were collected from the tested decks to be deeply investigated within the frame of BRIDGE|50 research project. The purpose of the preliminary test campaign is to characterize the dynamic behavior of the decks in their service condition. Dynamic measurements were acquired on each deck by using different excitation sources. The collected data have been analyzed in order to extract the principal modal components and the outcomes have been compared to the analytical results given by a FE model. The results of the tests will be used to better investigate the effectiveness of the dynamic tests in the assessment of ageing infrastructures, to explore the effects of damages on single beams and its influence on the global response of this bridge typology
Old men running: Mechanical work and elastic bounce
It is known that muscular force is reduced in old age. We investigate what are the effects of this phenomenon on the mechanics of running. We hypothesized that the deficit in force would result in a lower push, causing reduced amplitude of the vertical oscillation, with smaller elastic energy storage and increased step frequency. To test this hypothesis, we measured the mechanical energy of the centre of mass of the body during running in old and young subjects. The amplitude of the oscillation is indeed reduced in the old subjects, resulting in an approximately 20% smaller elastic recovery and a greater step frequency (3.7 versus 2.8Hz, p=1.9×10-5, at 15-17kmh-1). Interestingly, the greater step frequency is due to a lower aerial time, and not to a greater natural frequency of the system, which is similar in old and young subjects (3.6 versus 3.4Hz, p=0.2). Moreover, we find that in the old subjects, the step frequency is always similar to the natural frequency, even at the highest speeds. This is at variance with young subjects who adopt a step frequency lower than the natural frequency at high speeds, to contain the aerobic energy expenditure. Finally, the external work to maintain the motion of the centre of mass is reduced in the old subjects (0.9 versus 1.2Jkg-1m-1, p=5.1×10-6) due to the lower work done against gravity, but the higher step frequency involves a greater internal work to reset the limbs at each step. The net result is that the total work increases with speed more steeply in the old subjects than in young subjects. © 2007 The Royal Society

A Roberto,1 MT Greco,2 L Legramandi,3 F Galli,3 M Galli,4 O Corli1 1Pain and Palliative Care Research Unit, Oncology Department, IRCCS-Istituto di Ricerche Farmacologiche Mario Negri, Milan, Italy, 2Department of Clinical Sciences and Community, University of Milan, Milan, Italy, 3Methodology for Clinical Research Laboratory, Oncology Department, IRCCS-Istituto di Ricerche Farmacologiche Mario Negri, Milan, Italy, 4Scientific Medical Communication srl, Novara, Italy Background: Opioids are the most important pharmacological treatment for moderate-to-severe cancer pain, but side effects limit their use. Transdermal fentanyl (TDF) and oral prolonged-release oxycodone-naloxone (OXN-PR) are effective in controlling chronic pain, with less constipation compared to other opioids. However, TDF and OXN-PR have never been directly compared.Patients and methods: Cancer patients with moderate-to-severe chronic pain were consecutively enrolled in two prospective 28-day trials, received either TDF or OXN-PR, and were assessed at baseline and after 7, 14, 21, and 28 days. The primary endpoint was 28-day analgesic response rate (average pain intensity decrease ≥30% from baseline). Other outcome measures included opioid daily dose changes over time; need for adjuvant analgesics; number of switches; premature discontinuation; presence and severity of constipation; and other adverse drug reactions. To compare the efficacy and the safety of TDF and OXN-PR, we used the propensity score analysis to adjust for heterogeneity between the two patient groups.Results: Three hundred ten out of 336 patients originally treated (119 TDF and 191 OXN-PR) were included in the comparative analysis. The amount of responders was comparable after TDF (75.3%) and OXN-PR administration (82.9%, not significant [NS]). The final opioid daily dose expressed as morphine equivalent was 113.6 mg for TDF and 44.5 mg for OXN-PR (p<0.0001). A daily opioid dose escalation >5% was less common after OXN-PR (19.3%) than after TDS administration (37.9%, p<0.0001). Opioid switches and discontinuation were similar in both groups. Severe constipation in the two groups was comparable (32.6% after TDF vs 24.7% after OXN-PR, NS). Nausea, vomiting, and dry mouth were significantly less frequent in the OXN-PR group than in the TDF group.Conclusion: Despite a similar analgesic activity in moderate-to-severe cancer pain, OXN-PR is characterized by lower daily dosages, less need for drug escalation, and fewer side effects compared to TDF.

Design and Gamification for Reshaping Relations and Services in Social Cooperatives
It’s increasingly clear that design is no longer just an added value for business in contributing to developing better products, services and experiences; instead, it’s leading a new methodology in managing the process of innovation. In social cooperatives, design thinking is providing possibilities to better organize complex internal relationships in order to facilitate innovation process towards better services as final offerings.
The research team of Creative Industries lab is collaborating with a national organization with local structures for social and health care. This type of organizations is generally not considered within design-related fields, however, it's necessary to show up possible impacts and values of design for them. Thus, the research activities and intervention are aiming at supporting the organization in improving the quality and effectiveness of its offered services through reshaping the development approach and transforming the organization from results-oriented to capability-oriented.
The research has developed a gamificated co-design activity involved all the staffs of the organization as a “pilot” to test a new way to form organizational change. It had two specific objectives: the primary activity is to involve all the staffs in improving the sense of belonging and working motivation; the latter one is to develop a new strategy to facilitate care workers to participate in service innovation process, which is supported by specific designed toolkits
Metronomic Chemotherapy in Triple-Negative Metastatic Breast Cancer: The Future Is Now?
Triple-negative breast cancer (TNBC) shows a very bad prognosis, even in early stages of disease. Metronomic chemotherapy refers to the minimum biologically effective dose of a chemotherapy agent given as a continuous dosing regimen with no prolonged drug-free breaks that leads to antitumor activity. In the present article, we review preclinical and clinical data of metronomic administration of chemotherapy agents with or without biological agents in TNBC cell lines and patients, contextually reporting data from the VICTOR-2 study in the subgroup of patients with TNBC, in order to stimulate new ideas for the design of clinical trials in this subset of patients
Evaluating the Effects of an Ophthalmic Solution of Coenzyme Q10 and Vitamin E in Open-Angle Glaucoma Patients: A Study Protocol
Introduction: The CoQun\uae study is a multicenter, controlled trial aimed to evaluate the neuroprotective effects of Coqun\uae, an ophthalmic solution of Coenzyme q10 (CoQ10) and Vitamin E (VitE), in patients affected by primary open-angle glaucoma (POAG). Pre-clinical studies and small non-controlled clinical trials have previously shown a potential role of CoQ10 and VitE in glaucoma neuroprotection, both in vitro and in vivo. Methods: Randomized, parallel arm, multicenter, double-blind study. POAG patients with an IOP ranging from 17 to 21\ua0mm Hg on monotherapy with a prostaglandin analogue (PGA) will be considered for study enrollment. Inclusion criteria will be visual field (VF) mean deviation between 12\ua04 and 12\ua010\ua0dB and VF Pattern Standard Deviation between 4 and 10\ua0dB. Eligible patients will be randomized to receive CoQun\uae (Arm A) or placebo (Arm B), in addition to PGA monotherapy. Planned Outcomes: Primary outcome will be time to progression, defined as the time between the baseline visit and the visit with confirmed VF progression. A total of 612 patients are planned to be enrolled, to detect a hazard ratio of 0.65, with a power of 80% and an alpha error of 0.05 (two-sided). For study power calculation, 10% non-evaluable patients are assumed. This is the first study investigating, in a randomized, double-blind and controlled fashion, the neuroprotective effects of CoQ10 and VitE in POAG patients.

Oral prolonged-release Oxycodone-Naloxone: analgesic response, safety profile, and factors influencing the response in advanced cancer patients.
BACKGROUND: Oxycodone-Naloxone (OXN) aims to reduce opioid-related constipation while being successfully analgesic. METHODS: We evaluated the analgesic response, prevalence, and severity of side effects in 176 cancer patients with moderate to severe pain and treated with OXN. Patients were followed for 28 days and evaluated every seven. Pain intensity, changes of therapy, and adverse drug reactions were recorded at each visit. The primary efficacy endpoint was the proportion of responders (≥30% reduction of pain intensity from baseline to final) and final average pain score ≤4 on a 0-10 scale. RESULTS: Average and worst pain intensity, and breakthrough pain (BTP) prevalence decreased over time and 81.3% of patients were responders. The starting daily dose of OXN was raised from 25.1±13.0 mg to 44.1±29.9 mg, and dose escalation >5%/day was observed in 19.4% of patients; 40.8-46.2% and 11.0-17.0% experienced any and severe grade of constipation during the follow-up visit, respectively. Digestive system tumor, thyroid endocrinopathies, psychological irritability, and BTP increased the risk of analgesic non-response. CONCLUSIONS: OXN had strong analgesic effect in moderate to severe cancer pain patients: the safety profile is in line with the common adverse effects of opioids and severe constipation was uncommon
