A novel process for the complete recycling of exhausted coffee capsules with a fully circular approach: Design of the industrial plant and Techno-Economic analysis of the process.

The objective of this paper is to present the technical and feasibility analysis of an innovative mechanical recycling system for exhausted coffee capsules. This recycling process involved the sorting of spent coffee grounds (SGC) and the subsequent drying and melt-mixing of a portion of these grounds with the remaining capsule components, mainly composed of polypropylene (PP), along with optional virgin PP. These newly developed composite materials exhibited mechanical and rheological properties comparable or even surpassing those of virgin PP. They were also successfully utilized for the injection of new capsule shells, thus alignin with the principles of the circular economy. In addition to the technical aspects, this paper present a comprehensive Techno-Economic Analysis (TEA) of the proposed recycling processes, considering the inclusion of virgin PP (0-20 %) and the initial moisture content (MSGC) of SGC(5-55 %) as varying factors. An industrial plant, designed to handle up to 190 million exhausted coffee capsules and produce up to 1500 tons of recycled compund was appropriately sized. The analysis revealed that processes are profitable across all examined scenarios and that the Net Present Value ranged between 800 k€ (for vPP = 20 % and MSGC = 55 %) and 2000 k€ (for vPP = 0 % and MSGC = 5 %).

Effects of dietary supplementation with extruded linseed and oregano in autochthonous goat breeds on the fatty acid profile of milk and quality of Padraccio cheese.

The study aimed to evaluate the effects of linseed and oregano supplementation to the diet of goats on fatty acid profile and sensory properties of Padraccio, a typical cheese produced during spring through summer in the Basilicata region (southern Italy). Extruded linseed and dried oregano inflorescences were integrated in the pelleted concentrate supplementation (500 g/head per day) in 21 grazing goats that were randomly assigned, 7 per group, to the following experimental treatments: concentrate, concentrate with addition of linseed, and concentrate with addition of linseed and oregano. Pooled milk from each group was used in cheesemaking. From a nutritional perspective, integration of extruded linseed in the goat diet improved the fatty acid profile of Padraccio cheese. Moreover, the cheese from this group evidenced the highest scoring on color, flavor, texture, and overall liking.

Are there regional differences in the management of colon cancer in France?

The purpose of this study was to assess possible regional disparities in the management of colon cancer in France. In 1995, 1605 patients with a colon cancer in eight areas covered by a population-based cancer registry were studied. Pre-therapeutic work-up, stage at diagnosis and therapeutic modalities were assessed. There were no differences between areas concerning the resection or the stage at diagnosis. The proportion of patients with a colonoscopy alone varied between 42.7 and 70.4% (P<0.001). The use of both colonoscopy and barium enema was even more heterogeneous (extremes from 11.7 to 40.2%, P<0.001). There were significant differences in the performance of abdominal computed tomography and tumour markers. The number of examined lymph nodes was lower than the recommendation in 47.3% of cases with extremes ranging from 36.9 to 60.9%. Adjuvant chemotherapy was performed on average in 49.4% of cases in stage II (in which it is not recommended) with extremes from 18.8 to 72.5% (P<0.001) and in 79.6% of the cases in stage III (in which it is recommended) with extremes from 63.6 to 94.4% (P=0.08). In conclusion, these results should alert practitioners and health care authorities in order to homogenize practices.

Combined radiotherapy and chemotherapy (cisplatin and 5-fluorouracil) as palliative treatment for localized unresectable or adjuvant treatment for resected pancreatic adenocarcinoma: results of a feasibility study.

PURPOSE: To evaluate a cisplatin-containing chemoradiotherapy (CRT) regimen followed by chemotherapy for unresectable (locally advanced group, n = 32) and resected (adjuvant group, n = 10) pancreatic adenocarcinoma. The quality of palliation and percentage of secondary resections were also studied for unresectable disease. METHODS AND MATERIALS: The protocol comprised CRT (45 Gy over 5 weeks), combined with 5-fluorouracil and cisplatin during the first and fifth weeks, followed, 3 weeks later, by 4 cycles of the same chemotherapy plus leucovorin. RESULTS: All patients completed CRT but only 50% of each group finished the entire protocol. Gastrointestinal toxicity and weight loss were the major side effects during CRT. Enhanced hematological toxicity limited the post-CRT chemotherapy. For the locally advanced group, median survival was 9 months; 1- and 2-year survival rates were 31 and 12. 5%, respectively. The overall response rate was 16% and 50% had stable disease. A lasting palliative effect defined as improved performance status and decreased analgesic consumption, was recorded for 43% of the patients. Only three secondary resections have been performed. For the adjuvant group, median survival was 17 months. CONCLUSIONS: Although toxic in advanced disease, this regimen significantly lowered pain and analgesic consumption, but had poor impact on secondary resectability. In an adjuvant setting, although equally toxic, this series was too small to allow conclusions to be drawn.

[The ASL and hospitals: a model of emerging management]. / ASL e ospedali: un modello di gestione emergente.

The authors analysed the advantages and drawbacks of the legislative rules in the Italian medical services. They underline the impediments to the improvement in the quality and efficiency of both the organizing models and the control system of administration. The authors consider a new trend in the administration system taking place in the most innovative and dynamic units and they analyze the efficacy and speediness of diffusion of this new system. The new model could be extended to the ASL and Hospital as a possible improvement of the present situation. The article is structured in two main parts; in the first one the legal changing, that took place in the last year, in the organization of the national medical system is critically examined; the second one summarized the most significant innovation brought by the new administrative system of ASL and hospital.

The selection for shunting in patients with severe bilateral carotid lesions.

Patients with severe bilateral carotid lesions (stenosis and contralateral internal carotid occlusion) are at high risk of having a stroke, and carotid endarterectomy has been proposed as the best treatment. In spite of improvements in surgical technique, this operation is still associated with significant perioperative complications (5-13%) which are frequently (up to 40%) correlated with intolerance to internal carotid artery clamping. For this reason, intraoperative cerebral monitoring able to accurately detect ischaemia during surgery would be useful. Reviewing our experience from the last 7 years in 74 patients operated on for stenosis and contralateral occlusion of the internal carotid artery, we found a 1.3% neurological morbidity and 1.3% mortality rate. Presenting symptoms included focal transient ischaemia attacks (TIAs) in 57 patients, stroke in 16 patients and two patients were asymptomatic. Half of these patients (37) were operated on under general anaesthesia with electroencephalogram (EEG) monitoring, stump pressure measurement and selective shunting. In this group, two patients (5.4%) sustained a postoperative stroke, one of which was fatal. The remaining 37 patients were operated on under local-regional anaesthesia with selective shunting on the basis of neurological deficit onset or loss of consciousness during the test clamp. There were no postoperative neurological complications in this group but one patient died of acute myocardial infarction on the 6th postoperative day. This experience suggests that it is possible to perform carotid endarterectomy in patients with severe bilateral lesions with a postoperative complication rate similar to that in patients with less complicated obstructive lesions if accurate intraoperative cerebral monitoring is used.
