This research investigates the barriers impeding innovation within small- and medium-sized enterprises (SMEs) in Brazil, exploring 54 innovation-related barriers categorized into six distinct groups to offer substantial insights and analyses pertinent to the decision-makers, researchers and SMEs.

This research employed a mixed quantitative and exploratory approach, utilizing fuzzy Delphi, fuzzy analytic hierarchy process (AHP) and fuzzy decision-making trial and evaluation laboratory (DEMATEL) methods. The fuzzy Delphi method confirmed the categories and barriers through quantitative analysis, the fuzzy AHP ranked the validated obstacles and the fuzzy DEMATEL method identified causal connections among the top-priority barriers.

Out of 54 barriers, 23 significantly impacted SMEs. The “Financing and Financial” category was the most significant barrier, with “Access to Financing” being the most critical impediment. The barrier with the most influence was “Instability of Fiscal Policies,” and the highest causal priority was “Survival of the Priority Business,” identifying the government’s unstable fiscal policy as the principal barrier confronting SMEs in Brazil.

The primary challenges for Brazilian SMEs center on financing, fiscal policies and maintaining ongoing operations. By addressing these barriers and fostering a resilient business environment, SMEs’ innovation capabilities and competitiveness can be enhanced, serving as key drivers for sustainable economic growth in fluctuating economic conditions. This study contributes to the literature by highlighting and validating the main barriers to SME innovation, providing highly relevant information about the innovation process.

The purpose of this study is to nutritionally evaluate dams exposed to caloric restriction or cafeteria diets during the lactation period.

Twenty-four female Wistar rats (n = 8/group) and their respective litters received during lactation: Control (CTRL) – received standard chow; Caloric restriction (CR) – received 50% of the ratio of the CTRL group; Cafeteria diet (CAF) – received cafeteria diet. Weighing of the mother rats and their respective litters occurred weekly and the diets were daily. At weaning, levels of glucose, total cholesterol, high-density lipoprotein, low-density lipoprotein (LDL) and triglycerides were evaluated. Abdominal adipose tissue was removed and weighed. Liver tissue was removed to determine the lipid profile.

CR dams showed lower food (p < 0.01), caloric (p < 0.01) and all macronutrients (p < 0.01) intake. This group also observed intense weight loss (p < 0.01), in addition to low litter weight (p < 0.01). CAF dams had higher caloric intake (p < 0.05) and increased consumption of lipids (p < 0.01). The CAF group also reported greater accumulation of abdominal adipose tissue (p = 0.01), elevated levels of LDL (p < 0.01) and hepatic lipids (p < 0.01), as well as a litter with higher weaning weight (p < 0.01).

Few studies have evaluated the effects of different models of malnutrition focusing on dams. CR dams showed severe weight loss, which may have caused their pups to be underweight. On the other hand, the CAF diet during lactation led to a higher consumption of lipids and accumulation of adipose tissue, which generated a high weight of the litter.
