Background: Preoperative malnutrition is a significant factor in patients with pancreatic tumors undergoing pancreaticoduodenectomy. The aim of this study was to assess the association between preoperative malnutrition and delayed discharge within a ten-day timeframe and potential correlations between preoperative malnutrition and postoperative surgical complications. Methods: A retrospective cohort study was conducted, recruiting a final sample of 79 patients with benign or malignant cephalic pancreatic tumors from 2015 to 2022. The risk of malnutrition was assessed using the Malnutrition Universal Screening Tool, while length of hospital stay and relevant clinical data were extracted from clinical documentation. Results: The preoperative malnutrition risk was high in 21.52% of the sample, moderate in 36.71%, and low in 41.77%. Body mass index (BMI) (p = 0.007) and postoperative surgical complications (p < 0.001) were significantly correlated with delayed discharge. No statistically significant differences were found between levels of malnutrition risk and delayed discharge (p = 0.122), or postoperative surgical complications (p = 0.874). Conclusions: Postoperative complications and BMI emerge as significant risk factors. The limited sample size may have compromised the collection of homogeneous and significant data. Future studies should evaluate the implementation of personalized nutritional screening tools, nutritional assessment plans, and the involvement of specialized health professionals.

Background/Aim: Nutrition is a key element of the prehabilitation process prior to surgery. The aim of this study was to identify the clinical pathways of nutritional prehabilitation before cystectomy. Methods: A systematic literature review was conducted in PubMed, the Cochrane Library, CINAHL, Scopus and the Web of Science databases. Quality and risk of bias assessment was conducted adhering to the JBI framework and evidence was evaluated according to the Oxford Centre for Evidence Based Medicine levels of evidence. Results: Out of 586 records identified, six studies were included. Among them, only two were randomized controlled trials. Immunonutrition has been shown to improve postoperative bowel function (3.12 vs. 3.74 days; RR 0.82; CI, 0.73–0.93; p = 0.0029) and decrease postoperative complications (−36.7%; p = 0.008) and readmission rates (−15.38%; p = 0.03). Furthermore, oral nutritional supplements combined with nutritional counseling demonstrated an accelerated recovery of bowel function (−1 day; p < 0.01), a reduction in the length of hospital stay (−1.75 days; p = 0.01), an improvement in handgrip strength (+6.8%, p < 0.001), an increase in bone mass (+0.3 kg, p = 0.04), and a better BMI value (+2.3%, p = 0.001). Conclusions: Nutritional prehabilitation demonstrates potential in enhancing postoperative outcomes following radical cystectomy. Oral supplements, immunonutrition, and counseling exhibit efficacy in improving postoperative results.

Background: Clinical nutrition is essential in nursing care, with nurses playing a key role in supporting patients’ dietary needs. Aim: To assess the impact of active learning methodologies on clinical nutrition education, focusing on knowledge retention among nursing students. Methods: Using a quasi-experimental research design, we enrolled 131 s-year nursing students. Both groups attended an eight-hour seminar on clinical nutrition, incorporating critical thinking. The experimental group had prior exposure to active learning and ICT in their first-year course, while the control group received traditional teaching. Knowledge was assessed using a validated questionnaire on basic and clinical nutrition. Results: The experimental group scored higher in both basic and clinical nutrition, indicating that active learning improves immediate learning and long-term retention. One year later, they retained significant knowledge, particularly regarding nutrient–disease relationships. Conclusions: Active learning, particularly critical thinking, enhances short- and long-term outcomes in clinical nutrition education. Future studies should refine assessment tools and explore further integration of active learning into nursing curricula.

Starting Active Materials for Synthesis (SAMS) represents a critical stage in drug manufacturing, directly influencing the microbiological quality and safety of the final product. The introduction of SAMS marks the point where Good Manufacturing Practices (GMP) begin to apply, which are essential for ensuring sterility and preventing microbial contamination during the synthesis process. However, defining the exact point in the process that qualifies as the SAMS is subject to uncertainties, as earlier stages are not always governed by stringent GMP standards. The regulatory differences between various countries further contribute to this issue. This study explores the implications of SAMS selection and use in relation to sterility and infection control, analyzing the guidelines of major Regulatory Authorities and comparing their approaches to GMP. Regulations from several international regulatory agencies were examined, with a particular focus on microbiological control measures and infection protection in the SAMS manufacturing process. The analysis focused on the microbiological control requirements and safety measures applicable to the stages preceding the introduction of SAMS into the production of the final Active Pharmaceutical Ingredients (APIs). Documents published between 2015 and 2025 were included based on predefined criteria regarding relevance, accessibility, and regulatory authority. The analysis revealed significant discrepancies between regulations regarding the definition and management of SAMS. In particular, the regulations in Mexico and India have notable gaps, failing to provide clear guidelines on SAMS sterility and protection against infectious contamination. Conversely, China has introduced risk-based approaches and early-stage microbiological controls, especially for sterile products, aligning with international standards. The European Medicines Agency (EMA), the U.S. Food and Drug Administration (FDA), the Pharmaceutical Inspection Co-operation Scheme (PIC/S), and the World Health Organization (WHO) have well-established systems for microbiological quality control of SAMS, including rigorous measures for the validation of suppliers and risk management to ensure that SAMS does not compromise the microbiological safety of the final product. The regulations in Brazil and Canada introduce additional measures to protect the microbiological quality of SAMS, with specifications for contamination control and certification of critical stages. The lack of a harmonized language for the definition of SAMS, coupled with a fragmented regulatory framework, presents a challenge for infection protection in pharmaceutical manufacturing. Key issues include the absence of specific regulations for stages prior to the introduction of SAMS and the lack of standards for inspections related to these stages. A desirable solution would be the mandatory extension of GMPs to the stages before SAMS introduction, with centralized control to ensure sterility and protection against infection throughout the entire manufacturing process.

Background/Aim: Nutritional management in neurosurgical patients with brain neoplasms is critical, as optimal nutritional status is potentially associated with improved clinical outcomes. This systematic review aimed to analyze the impact of pre- and postoperative nutritional assessment and effect of prepost interventions on the clinical outcomes. Methods: A systematic review was conducted using the PubMed, Cochrane Library, Embase, and CINAHL databases, complemented by a search of grey literature. Study quality was assessed using the Joanna Briggs Institute framework, and the certainty of evidence was graded according to the Oxford Centre for Evidence-Based Medicine levels. Results: Fourteen studies, encompassing a total of 11,224 adult patients with brain neoplasms, were included. Many of these studies were retrospective, had small sample sizes, and examined diverse nutritional protocols. Preoperative nutritional status assessment, including clinical parameters such as albumin (p < 0.001), Controlling Nutritional Status score (p = 0.001), and Prognostic Nutritional Index (p < 0.010), combined with postoperative oral nutritional supplements (p < 0.001), was significantly associated with postoperative clinical outcomes. Additionally, personalized nutritional counseling contributed to a reduction in complications and facilitated more effective functional recovery. Conclusions: Nutritional care is vital in managing neurosurgical patients with brain neoplasms, reducing complications and enhancing postoperative recovery and overall clinical outcomes. A multidisciplinary team is key to optimal outcomes. Future research should aim to standardize protocols for broader applicability.

Background: Surgical site infections (SSIs) are among the most common postoperative complications. Environmental factors, including intraoperative traffic and door openings in the operating room (OR), have been identified as critical contributors to microbial air contamination. Nurses play a pivotal role in managing these factors, directly influencing infection control practices. Methods: An integrative review was conducted to synthesize current evidence on the association between intraoperative traffic, door openings, and SSIs. A structured methodology was employed to identify, assess, and analyze the existing literature, with a specific focus on the nursing role in infection prevention. Results: Findings from a single-center prospective cohort study indicate that ORs with more than 10 personnel present exhibit a threefold increase in SSI risk [Relative Risk (RR) = 3.12; 95% Confidence Interval (CI): 0.71–13.66] compared to ORs with fewer personnel. Additionally, every five door openings per procedure were associated with a significant increase in SSI incidence [Hazard Ratio (HR) = 2.00; 95% CI: 1.24–3.20, p = 0.005]. Conclusions: These findings underscore the importance of strict protocols to limit intraoperative traffic and unnecessary OR access. A multidisciplinary approach plays a crucial role in ensuring surgical safety and preventing SSIs by regulating OR access and adhering to infection control best practices.
