Background: ChatGPT has been largely discussed since it was launched in November 2022. Problem statement: the main approaches of ChatGPT in the recent and scarce literature are more focused on the ...impacts for general use, applied sciences and educational systems, which evidences a relevant gap for the management field, especially related to the supply chain area. Objectives: as a novel and initial contribution, this article aims to provide a viewpoint with the main applications and other issues regarding ChatGPT in supply chains, based on the initial discovered evidence. Methods: This viewpoint article is grounded on the few articles available in specialized magazines, blogs and company websites that approach potential applications and other issues of ChatGPT in supply chains, as a systematic literature review was not possible due to the absence of papers approaching the subject in the research databases. Contributions: this article contributes to the practitioners involved in supply chain activities who desire to have an initial and structured content related to the impacts and applications of ChatGPT on supply chains. It also seeks to encourage researchers on further research deployments in this field by presenting potential research agenda topics. Results: first evidence based on quality results from the analyzed content showed that, although it may take time until this technology evolves to a desirable level of maturity, it may be applied in different areas of supply chain management (e.g., route optimization, predictive maintenance, order shipment, customer and supplier relationships, data analysis, ordering process, automating invoices, reducing waste, workforce training and guidance, amongst others), with a potential generation of significant benefits such as cost reductions and the improvement of supply chain performance.
Studies using the Global Leadership Initiative on Malnutrition (GLIM) criteria for patients with liver cirrhosis are limited. This study aimed to assess the impact of malnutrition according to the ...GLIM criteria on the outcomes of patients awaiting a liver transplant (LTx) and compare these criteria with Subjective Global Assessment (SGA).
This retrospective observational study included adult patients awaiting LTx. Patient clinical data, nutritional status according to various tools including SGA, and resting energy expenditure were assessed. The distinct phenotypic and etiologic criteria provided 36 different GLIM combinations. The GLIM criteria and SGA were compared using the kappa coefficient. The variables associated with mortality before and after the LTx and with a longer length of stay (LOS) after LTx (≥18 days) were assessed by Cox regression and logistic regression analyses, respectively.
A total of 152 patients were included median age 52.0 (interquartile range: 46.5–59.5) years; 66.4% men; 63.2% malnourished according to SGA. The prevalence of malnutrition according to the GLIM criteria ranged from 0.7% to 30.9%. The majority of the GLIM combinations exhibited poor agreement with SGA. Independent predictors of mortality before and after LTx were presence of ascites or edema (p = 0.011; HR:2.58; CI95%:1.24–5.36), GLIM 32 (PA-phase angle + MELD) (p = 0.026; HR:2.08; CI95%:1.09–3.97), GLIM 33 (PA + MELD-Na≥12) (p = 0.018; HR:2.17; CI95%:1.14–4.13), and GLIM 34 (PA + Child–Pugh) (p = 0.043; HR:1.96; CI95%:1.02–3.77). Malnutrition according to GLIM 28 (handgrip strength + Child-Pugh) was independently associated with a longer LOS (p = 0.029; OR:7.21; CI95%:1.22–42.50).
The majority of GLIM combinations had poor agreement with SGA, and 4 of the 36 GLIM combinations were independently associated with adverse outcomes.
This paper aims to present a structured perspective regarding the strategic sourcing process with the aim of enhancing supply chain resilience during disturbing events. For this purpose, it uses a ...descriptive approach, based on theoretical insights in order to provide a detailed strategic sourcing process, which adopts a risk‐based orientation. Each of the five main steps of the strategic sourcing process that are identified have aspects related to the supply chain resilience that need to be taken into consideration on the sourcing decision‐making. The framework that is presented provides relevant insights regarding on how to effectively conduct the strategic sourcing process with the prescription that decision‐making needs to be transparent. It is hoped that the constructs presented in this paper encourage researchers to conducting empirical studies in order to obtain evidence related to the strategic sourcing process and its relations with supply chain resilience. The proposed framework of this paper, can also potentially support practitioners involved in the procurement and strategic sourcing activities by providing an effective guidance as to how to appropriately engage in decision‐making with respect to strategic sourcing. The approach proposed is unique, bringing a timely and novel approach by relating strategic sourcing with supply chain resilience during disturbing events.

Circular economy can play an important role towards sustainable business management and it can be seen all throughout an organization. Although the current literature regards the circular economy as ...a guide for more sustainable business models, it is not clear the main implications to key business areas. Therefore this study aimed to present the key impacts of circular economy practices within different business areas that help guide a sustainable management of businesses. To that end, it was identified, by means of a systematic review of the existing literature, the business areas impacted by circular economy practices within an organization. The business areas identified were strategic planning, cost management, supply chain management, quality management, environmental management, process management, logistics and reverse logistics, service management, and research and development, allowing a discussion on the main contributions of the circular economy to each area. A key-impact map was provided summarizing the most influential changes in each area that assist in the management of businesses towards greater sustainability. It is important that organizations understand and accurately internalize circularity principles within their strategic plan. On that note, adopting a circular thinking might enable an organization to obtain more sustainable (economic) results while reducing impacts.

•Bioelectrical impedance vector analysis is a promising alternative for the assessment of patients with liver cirrhosis.•Resistance and reactance are used to assess the nutrition and hydration ...status.•The vector placement had a prognostic effect in patients awaiting liver transplant.•Fluid retention and malnutrition predicted the vector placement in quadrant 4.
The aim of this study was to assess patients on the waiting list for liver transplant (LTx) according to bioelectrical impedance vector analysis (BIVA), as well as to verify the association between the placement of the vectors on the graph with clinical outcomes and identify the predictors to vector placement in quadrant 4 (Q4; indicating more hydration and less cellularity).
This was a retrospective observational study including 129 patients ≥20 y of age awaiting LTx. Patients’ nutritional status was assessed by using different tools, including single-frequency bioelectrical impedance analysis and the Subjective Global Assessment (SGA). Clinical data were registered. The BIVA was evaluated by comparing the individual vectors plotted for all patients to the tolerance ellipses of 50%, 75%, and 95% of the reference healthy population. The quadrant of the vector for each patient was registered.
The majority of the vectors were placed in Q1 (n = 54; 41.9%) and Q4 (n = 39; 30.2%). The presence of ascites or edema (hazard ratio HR, 2.43; 95% confidence interval CI, 1.15–5.12; P = 0.019) and the BIVA vector placed in Q4 in any ellipse (HR, 2.10; 95% CI, 1.07–4.09; P = 0.029) were independent predictors for mortality on the waiting list or ≤1 y after LTx. BIVA was not associated with longer hospital length of stay. The predictors of vector placement in Q4 were higher age, malnutrition according to SGA, and presence of ascites or edema.
Patients on the waiting list for LTx with BIVA vectors placed in Q4, in the 50%, 75%, or 95% tolerance ellipses, presented a worse prognosis.
