Early hydrogen excretion peaks during breath tests. Small intestinal bacterial overgrowth or accelerated transit?
No full textLongterm outcome of acute severe ulcerative colitis in the rescue therapy era: a multicentre cohort study
No full textBackground: Small intestinal bacterial overgrowth (SIBO) has been reported with varying prevalence, de- pending upon the criteria used for diagnosis. Lactulose and glucose breath tests are the most used in clinical settings. Early rises of hydrogen excretion during a lactose breath test suggest SIBO, but the find- ing could result from accelerated mouth-to-caecum transit time. Aims: Defining the prevalence of early hydrogen peaks during lactose breath tests and assessing the proportion of patients affected by SIBO. Methods: An early ( ≤60 ) hydrogen excretion peak was observed in 120/663 patients with positive lac- tose hydrogen breath test. Eighty-one of them underwent a 50 g-9sample-glucose hydrogen breath test to diagnose SIBO. Results: The glucose breath test proved positive in 11/81 (13.6%) patients. The positivity rate was 18.2% (2/11) in those with the first peak detected at 30 and 12.8% (9/70) in those with the peak occurring at 60 . Conclusions: Early hydrogen excretion peaks are rarely associated with SIBO. The low positive predictive value indicates that the finding does not help identifying patients at high risk for this condition. Indi- rectly, the present data support the opinion that the prevalence of SIBO diagnosed by standard lactulose breath tests is much lower than reported, and the reliability of the test is low
Guiding manufacturing companies towards digitalization a methodology for supporting manufacturing companies in defining their digitalization roadmap
Full text linkWithin the era of Industry 4.0, digital technologies are seen as the main drivers for manufacturing industry transformation. In fact, many sustain that manufacturing companies will be able to obtain many benefits and opportunities from the digital transformation. If on one hand manufacturing companies have to be able to “ride” this wave of transformation in order to remain competitive, on the other hand, before investing in digital technologies, they have to understand what their current situation is and what their needs are with respect to
both digital technologies and organizational processes in different functions. Indeed, the success of the transformation process mainly depends on the company ability to be ready to apply the technological change that some of these digital technologies envision. From these considerations, after having figured out their current readiness level for starting the digital transformation fostered by the Industry 4.0, it is possible to state that the next step manufacturing companies have to undertake is to define their transformation roadmap. With the aim to
guide them towards this transformation process, a maturity model, called DREAMY (Digital REadiness Assessment MaturitY model) and based on the inspiring principles of the CMMI (Capability Maturity Model Integration) framework, has been developed and utilized. The objectives of this model are twofold. Firstly, it allows the assessment of the current digital readiness of manufacturing companies and the identification of their strengths and weaknesses with respect to implemented technologies and organizational processes. Secondly, it
enables the identification of a set of opportunities offered to companies by the digital transformation, considering their strengths and aiming to overcome their weaknesses. Through the application of this methodology into case studies, it has been possible to reach two main results. On one hand, the analyzed manufacturing companies have been aware of their digital readiness level, of their strengths and weaknesses and of the main opportunities they can exploit from the digitalization process starting from their current situation. On the other hand, empirical evidences were gathered on the current level of manufacturing companies’ digital readiness and on the possible
common traits among the identified opportunities
Initiating an Industrial Machinery Producer to Digital Servitization: A Case Study
Full text linkSeveral manufacturing companies are coping with the need to change their business model, being compelled to provide smart, connected and servitized solutions to their customers to survive in the market. A strategic trigger and catalyst of such a transition is represented by digital technologies. Embedded on physical products, digital technologies enable knowledge-based services capable not only of monitoring but also of controlling and optimize, sometimes even at an autonomous level, the system provided to the customer. However, several hurdles (categorized in technical/technological, organizational, human resources-related, and customer-related) can be met along the digital servitization path. It is still not clear what should be implemented in a company internally realizing the need of implementing the digital servitization transition. This paper has the aim of conducting a strategic analysis to understand how to initiate to the digital servitization phenomenon a company producing machineries for the decoration of plastic objects and containers
