Fluid assisted Alpine fissure-vein and cleft formation starts at prograde, peak or retrograde metamorphic conditions of 450-550 °C and 0.3-0.6 GPa and below, commonly at conditions of ductile to brittle rock deformation. Early-formed fissures become overprinted by subsequent deformation, locally leading to a reorientation. Deformation that follows fissure formation initiates a cycle of dissolution, dissolution/reprecipitation or new growth of fissure minerals enclosing fluid inclusions. Although fissures in upper greenschist and amphibolite facies rocks predominantly form under retrograde metamorphic conditions, this work confirms that the carbon dioxide fluid zone correlates with regions of highest grade Alpine metamorphism, suggesting carbon dioxide production by prograde devolatilization reactions and rock-buffering of the fissure-filling fluid. For this reason, fluid composition zones systematically change in metamorphosed and exhumed nappe stacks from diagenetic to amphibolite facies metamorphic rocks from saline fluids dominated by higher hydrocarbons, methane, water and carbon dioxide. Open fissures are in most cases oriented roughly perpendicular to the foliation and lineation of the host rock. The type of fluid constrains the habit of the very frequently crystallizing quartz crystals. Open fissures also form in association with more localized strike-slip faults and are oriented perpendicular to the faults. The combination of fissure orientation, fissure quartz fluid inclusion and fissure monazite-(Ce) (hereafter monazite) Th-Pb ages shows that fissure formation occurred episodically (1) during the Cretaceous (eo-Alpine) deformation cycle in association with exhumation of the Austroalpine Koralpe-Saualpe region (~ 90 Ma) and subsequent extensional movements in association with the formation of the Gosau basins (~ 90-70 Ma), (2) during rapid exhumation of high-pressure overprinted Briançonnais and Piemontais units (36-30 Ma), (3) during unroofing of the Tauern and Lepontine metamorphic domes, during emplacement and reverse faulting of the external Massifs (25-12 Ma; except Argentera) and due to local dextral strike-slip faulting in association with the opening of the Ligurian sea, and (4) during the development of a young, widespread network of ductile to brittle strike-slip faults (12-5 Ma)., Supplementary Information: The online version contains supplementary material available at 10.1186/s00015-021-00391-9., Competing Interests: Competing interestsThe authors declare that they have no conflict of interest., (© The Author(s) 2021.)

Background: Return to work (RTW) is a major goal to promote cancer survivors' social participation., Objective: This study describes the multidisciplinary social-healthcare pathway called UNAMANO, conceived to support RTW in this population., Methods: UNAMANO was developed by the Azienda USL-IRCCS di Reggio Emilia, in partnership with the local branch of the Italian Medical Association, nonprofit associations, vocational training institutions, social cooperatives, a labour union, and a chartered accounting firm., Results: UNAMANO is directed towards employed individuals diagnosed with cancer living in the province of RE. It was developed through four actions: A) training healthcare professionals on work-related occupational rehabilitation; B) dissemination among community and stakeholders; C) recruitment and training of volunteers; D) cancer survivor engagement and provision of a personalized comprehensive intervention. This consists in providing information and either occupational therapy to overcome barriers and facilitate RTW or social support through re-training and tailored job search strategies based on individual risk of job loss., Conclusions: UNAMANO is the first Italian multidisciplinary social-healthcare pathway supporting RTW of cancer survivors. Addressing a wide area of cancer survivors' needs, it provides personalized intervention to resolve work-related issues. We propose this patient-centred RTW model to promote an easier transition from hospital to community.

Purpose: Little is known about return to work (RTW) of cancer survivors (CSs) in Central and Southern Europe. This study investigates the RTW rate of Italian CSs, describes their sick leave (SL) pattern, and explores factors affecting their RTW process., Methods: A population-based cross-sectional survey involving CSs registered at the Cancer Registry of Reggio Emilia Province (Italy) was launched in July 2016. Eligibility was restricted to individuals with first diagnosis of cancer in 2012 (stages I-III), aged 20-59, and employed at the time of diagnosis., Results: Of the 266 individuals interviewed, 140 (52.6%) were reintegrated without difficulty, 113 (42.5%) returned to work with some difficulty, and 13 did not RTW (4.9%). The majority of CSs (56%) took SL for some periods during treatment. Age > 50 years and higher income seemed to facilitate RTW (RR = 0.65, 95% CI 0.49-0.88 and RR = 0.72, 95% CI 0.54-0.97, respectively), while being divorced acted as a barrier compared to being married (RR = 1.45, 95% CI 1.04-2.01). Individuals uncertain about the type of company they were working for reported greater difficulty in RTW (RR = 1.68, 95% CI 1.03-2.72). Individuals who had undergone chemotherapy and those perceiving physical limitations had a higher risk of difficulty in the RTW process (RR = 1.79, 95% CI 1.42-2.24 and RR = 1.59, 95% CI 1.25-2.02, respectively)., Conclusions: Most CSs did RTW, with 2/3 combining work and treatment. However, almost half reported difficulty in RTW process. Factors affecting this process should be addressed throughout context-specific social and healthcare pathways aimed at preventing difficulties and potential job loss in this population.
