Introduction: Frailty syndrome is an increasingly recognized condition that affects a considerable proportion of elderly patients, particularly those undergoing major surgeries. In this meta-analysis, we aimed to systematically review and pool data from cohort studies to assess the effect of frailty on the clinical outcomes of patients undergoing esophagectomy for esophageal cancer. Methods: Major online medical databases such as PubMed, Embase, Scopus, and Web of Science were searched to gather all studies on the clinical outcomes of patients with frailty syndrome who underwent esophagectomy due to esophageal cancer. The study included articles published up to March 2026. Finally, 15 articles matched the required criteria and were included in this meta-analysis. Results: The pooled odds ratio for surgery-related mortality in patients with frailty syndrome and esophageal cancer undergoing esophagectomy has been established at 4.03 (Lower Limit: 2.20; Upper Limit: 7.38; p-value < 0.05). The pooled odds ratio for surgery-related postoperative pneumonia in patients with frailty syndrome and esophageal cancer undergoing esophagectomy has been established at 1.86 (Lower Limit: 1.16; Upper Limit: 2.98; p-value < 0.05). The pooled odds ratio for surgery-related postoperative cardiac complications in patients with frailty syndrome and esophageal cancer undergoing esophagectomy has been established at 1.73 (Lower Limit: 1.54; Upper Limit: 1.94; p-value < 0.05). Conclusions: Frailty is a powerful predictor of mortality in patients undergoing esophagectomy, with frail individuals facing nearly four times higher odds of death. This underscores the urgent need to integrate frailty assessments into standard preoperative screening to enhance risk stratification and optimize perioperative decision-making. A multidisciplinary approach is essential to improving resilience, recovery, and long-term survival in frail esophageal cancer patients. Future large-scale prospective trials should focus on standardizing assessment tools and evaluating the lasting impact of tailored interventions to ultimately enhance patient outcomes.

Background: There has been an increasing global prevalence of depression and other psychiatric diseases in recent years. Perceived stress has been proven to be associated with psychiatric and somatic symptoms. Some animal and human studies have suggested that consuming foods abundant in lignans and phytosterols may be associated with lower levels of stress, depression, and anxiety. Still, the evidence is not yet strong enough to draw firm conclusions. Thus, we investigated the association between dietary intake of these phytochemicals and the level of stress experienced by adult individuals. Methods: Diet was assessed using self-reported 7-day dietary records. The intakes of lignans and phytosterols were estimated using databases with their content in various food products. The Perceived Stress Scale (PSS) was implemented to measure the level of perceived stress. A logistic regression analysis was used to test for associations. Results: The odds of elevated PSS were negatively associated with dietary intake of total phytosterols, stigmasterol, and β-sitosterol, with evidence of a decreasing trend across tertiles of phytochemicals. The analysis for doubling the intake reinforced the aforementioned relationships and found protective effects against PSS for total lignans, pinoresinol, and campesterol. Conclusions: Habitual inclusion of lignans and phytosterols in the diet may play a role in psychological health. To address the global outbreak of depression and other mental health issues triggered by stress, it is important to take a holistic approach. There is a need to develop effective strategies for prevention and treatment, among which certain dietary interventions such as consumption of products abundant in lignans and phytosterols may play a substantial role.

Introduction Sarcopenia, characterized by a progressive loss of skeletal muscle mass and function, significantly affects older adults, particularly those with cancer. Although sarcopenia’s negative influence on quality of life (QoL) is acknowledged, data on its specific impact among older hospitalized oncology patients remain limited. The aim of the present study was to assess the health-related quality of life in older patients (≥ 65 years) diagnosed with gastrointestinal cancer using the SarQoL^® questionnaire and to analyze the association between weight loss and functioning across individual quality of life domains. Methods This cross-sectional study included 97 consecutive patients (≥ 65 years) diagnosed with gastrointestinal cancer, hospitalized at the University Hospital in Krakow between June and September 2023. Participants completed the SarQoL^® questionnaire, assessing QoL across seven domains: physical and mental health, locomotion, body composition, functionality, activities of daily living, leisure activities, and fears. Nutritional status was evaluated using Nutritional Risk Screening 2002 (NRS-2002). Results Patients had moderate impairment in overall QoL (mean SarQoL^® score: 61.7 ± 15.4/100). Lowest scores were observed in leisure activities (55 points), while highest scores occurred in fears (83 points). A significant but weak inverse correlation was observed between body weight and functionality (r = -0.225 ; p < 0.05) and fears domains (r = -0.255 ; p < 0.05), indicating higher QoL scores with lower body weight. Notably, patients with higher NRS scores paradoxically reported better functionality (r = 0.213 ; p < 0.05). Additionally, subjective physical weakness strongly correlated with mobility limitations and fatigue during walking (p < 0.001). Conclusions Sarcopenia substantially impairs QoL in older oncology patients, especially regarding leisure and functionality domains. The SarQoL^® questionnaire is effective in identifying nuanced impacts of sarcopenia on QoL. Early nutritional and rehabilitative interventions tailored to these insights could significantly enhance patient care and QoL outcomes.
