Purpose Neutropenic diet (ND) has historically been recommended to reduce infectious complications in patients with cancer. Although its use has declined over the past decade, recent studies, particularly in patients undergoing hematopoietic stem-cell transplantation (HSCT), have renewed concern regarding the safety of a liberalized diet (LD). We performed a meta-analysis of studies comparing ND with LD in patients with cancer. Methods We searched MEDLINE, Embase, and Cochrane databases from inception through January 2026. Comparative studies evaluating ND versus LD in adults or children with cancer were included. Primary outcomes were major infections and bacteremia/fungemia; secondary outcomes were pneumonia, diarrhea, and mortality. Random-effects meta-analyses were performed to calculate pooled relative risks (RRs) with 95% CIs. Results Fifteen studies including 4,320 patients met criteria for analysis. ND was not associated with significant differences in major infections (RR, 1.02 [95% CI, 0.88 to 1.18]; P = .795), bacteremia/fungemia (RR, 0.97 [95% CI, 0.78 to 1.22]; P = .805), pneumonia (RR, 0.98 [95% CI, 0.59 to 1.63]; P = .933), diarrhea (RR, 1.12 [95% CI, 0.96 to 1.31]; P = .159), or mortality (RR, 0.94 [95% CI, 0.77 to 1.15]; P = .632). Sensitivity analyses restricted to randomized controlled trials (RCTs) were consistent. In hematologic malignancy/HSCT studies (9 studies; 1,769 patients), no differences were observed across outcomes. In RCTs limited to these patients (6 studies; 855 patients), ND was associated with lower bacteremia/fungemia risk (RR, 0.67 [95% CI, 0.47 to 0.95]; P = .023), with no differences in other outcomes. Conclusion ND was not associated with reductions in major infections, pneumonia, diarrhea, or mortality compared with LD. These findings do not support routine implementation of ND for patients with short-term neutropenia or lower-risk cancer populations although selected high-risk patients, particularly those undergoing HSCT or experiencing prolonged neutropenia related to hematologic malignancies, may still warrant cautious dietary practices.

Abstract Background Immunosuppression is a recognized risk factor for severe and disseminated coccidioidomycosis; however, data describing outcomes in patients with inflammatory bowel disease (IBD) receiving advanced therapy, including biologics and small molecules, remain limited. We aim to describe the prevalence, clinical presentation, treatment patterns, and outcomes of coccidioidomycosis in IBD patients receiving advanced therapy at an endemic tertiary care center. Methods We performed a retrospective observational study of adult patients with IBD at Mayo Clinic Arizona diagnosed with coccidioidomycosis between 2023 and 2026. Patients were included if IBD diagnosis preceded coccidioidomycosis diagnosis and advanced therapy had been active for at least 4 weeks before infection. Cases were classified as proven, probable, or possible based on microbiologic, clinical, radiographic, and serologic criteria. Clinical outcomes included antifungal treatment duration, hospitalization related to coccidioidomycosis or IBD, IBD treatment modification after diagnosis, re-emergence of coccidioidomycosis symptoms, and IBD-related surgery. Results A total of 48 patients met inclusion criteria. Among 1083 tested IBD patients receiving advanced therapy, coccidioidomycosis positivity prevalence was 4.4% when including all serologically positive patients and 1.9% when restricted to proven or probable cases. The median age at coccidioidomycosis diagnosis was 40 years (range 19-87 years), and 30 (62.5%) of 48 had Crohn’s disease. Proven or probable infection was identified in 21 (43.8%) of 48 patients, while 14 (29.2%) of 48 patients were classified as possible. Antifungal therapy was prescribed in 32 (66.7%) of 48 patients, including all proven cases, 15 (88.2%) of 17 probable cases, 9 (64.3%) of 14 possible cases, and 3 (25.0%) of 12 nondiagnostic cases. Among proven/probable/possible cases, the median antifungal treatment duration was 174 days (range 8-831 days). Advanced IBD therapy was continued in 3 (75.0%) of 4 proven cases, 9 (52.9%) of 17 probable cases, 12 (85.7%) of 14 possible cases, and all nondiagnostic cases. Hospitalization occurred in 6 (12.5%) of 48 of the cohort, all of which were proven/probable cases. Most patients remained on advanced therapy after diagnosis, although tumor necrosis factor α inhibitors were the most interrupted or discontinued agents. Conclusions In this endemic tertiary care cohort, management decisions varied according to diagnostic certainty. Patients with proven or probable coccidioidomycosis were more likely to receive antifungal therapy and undergo advanced IBD therapy modification, whereas most patients with possible or nondiagnostic serologic findings remained on advanced therapy without major IBD-related complications. Prolonged antifungal treatment was common, highlighting the complexity of managing coccidioidomycosis in immunosuppressed patients with IBD.

Background: Given aspirin’s biologic plausibility for antifibrotic and antineoplastic effects, we conducted a systematic review and meta-analysis to examine the association between aspirin use and major liver-related outcomes in metabolic dysfunction-associated steatotic liver disease (MASLD). To our knowledge, this is the first systematic review and meta-analysis restricted exclusively to patients with biopsy- or registry-confirmed MASLD. Methods: A comprehensive search of Ovid MEDLINE, Ovid EMBASE, Scopus, and Web of Science was performed in October 2025. Studies enrolling adults with a confirmed MASLD diagnosis were included; those with viral hepatitis or alcohol-related liver disease were excluded. Outcomes assessed included hepatocellular carcinoma (HCC), fibrosis progression, cirrhosis, all-cause and liver-related mortality, gastrointestinal (GI) bleeding, hemorrhagic stroke, and liver disease progression. Hazard ratios (HRs) with 95% CIs were pooled using random-effects models. Heterogeneity was assessed using I2 statistics. Results: Seven studies met the eligibility criteria, with approximately 720,000 individuals included. Pooled analysis showed that aspirin use was associated with a significantly lower HCC risk (HR 0.59; 95% CI 0.43–0.81; I2 = 83%). No statistically significant association was found between aspirin use and cirrhosis incidence (HR 0.55; 95% CI 0.13–2.37; I2 = 83.4%) or GI bleeding (HR 1.11; 95% CI 0.74–1.66; I2 = 98.9%). Among the two studies that explored all-cause mortality, aspirin was associated with a modest but statistically significant reduction in all-cause mortality (HR 0.86; 95% CI 0.78–0.95; I2 = 0%). Conclusions: Aspirin use is associated with a reduced risk of HCC and all-cause mortality in MASLD without significantly increasing GI bleeding or hemorrhagic strokes. These associations may reflect aspirin’s anti-inflammatory properties in liver disease. Further RCTs are needed to verify the causal role of aspirin in MASLD management.
