The aim of the present study was to determine the effectiveness of combined exercise and nutrition interventions on physical function and quality of life (QOL) in patients with acute leukemia or malignant lymphoma (ML) during inpatient chemotherapy. The study was a randomized controlled trial where patients with acute leukemia or ML who were receiving inpatient chemotherapy and exercise therapy were divided into an intervention group (IG) and a control group (CG). Both groups underwent resistance training and aerobic exercise. The patients in the IG were instructed to take nutritional supplements twice a day. Assessment items were muscle strength (handgrip strength and knee extension strength), 6-min walking test, skeletal muscle mass, QOL, nutritional status, and fatigue. Two-way analysis of variance showed a significant interaction for bilateral handgrip strength and knee extension strength. No significant interactions were found for the other items. The results of the present study showed improved muscle strength in the IG compared to the CG, indicating the effectiveness of combined exercise and nutrition interventions during inpatient chemotherapy in patients with acute leukemia or ML.

Objectives: Evidence regarding the association between tea consumption and bladder cancer (BC) risk is inconsistent. This study aimed to increase our knowledge of the association by using international data from the Bladder Cancer Epidemiology and Nutritional Determinants Consortium.

Methods: Individual data on 2,347 cases and 6,871 controls from 15 case-control studies with information on black, green, herbal, or general tea was pooled. The association was estimated using multilevel multivariable logistic regression analysis adjusted for multiple (non-)dietary factors.

Results: Association between tea consumption and BC risk was observed (odds ratio, OR = 0.72, 95% confidence interval, 95% CI = 0.65-0.80) compared to non-tea drinkers. Stratified analyses based on gender and smoking status yielded similar results. Stratified analysis showed no significant association between black or green tea consumption and BC risk across models, while herbal tea consumption was linked to a reduced BC risk (OR = 0.59, 95% CI = 0.36-0.96). As daily tea consumption increased within a suitable range (<5.67 cups/day), BC risk decreased.

Conclusions: Camellia sinensis tea showed no association with BC risk, while herbal tea was inversely linked to BC incidence. Despite some significant findings in the selected strata, further studies are required to clarify the underlying mechanisms.

This study aimed to evaluate the effect of vitamin D (VD) supplementation on the pathological complete response (pCR) rate in women with breast cancer (BC) undergoing neoadjuvant chemotherapy (NCT). A randomized clinical trial was conducted with 80 women aged ≥45years with BC who were eligible for NCT. Women were randomized into two groups: VD group, daily supplementation with 2,000IU of cholecalciferol (n = 40) or placebo (n = 40), for 6 months. The primary outcome measure was the pCR rate. Serum 25-hydroxyvitamin-D [25(OH)D] levels were measured after BC diagnosis and the end of NCT. Of the 80 randomized women, 75 completed the NCT and underwent surgery. Baseline 25(OH)D values indicated hypovitaminosis D in both groups (VD: 19.6 ± 5.8 ng/mL and placebo: 21 ± 7.9 ng/mL, p = 0.33). After 6 months, 25(OH)D levels increased in the VD group compared to the placebo group (28 ± 8.7 vs. 20.2 ± 6.1 ng/mL, p = 0.03). The pCR rate was higher in women supplemented with VD when compared than the placebo (43% vs. 24%, p = 0.04). Adjusted logistic regression showed that women with 25(OH)D levels ≥20ng/mL were more likely to achieve pCR (OR3.65, 95%CI 1.09-12.8, p = 0.04). Women with BC undergoing NCT who received supplementation with 2,000IU of VD were more likely to achieve a pathological complete response than women in the placebo group.

Objective: This study aims to evaluate the effects of a problem-oriented nursing model combined with early enteral nutrition (EEN) during the perioperative period in patients with stage II/III gastric cancer (GC).

Methods: One hundred patients with stage II/III GC were randomly divided into a control group (conventional perioperative care and routine nutritional support) and an intervention group (problem-oriented nursing model plus EEN). Clinical outcomes, body mass index (BMI), emotional status, nutritional and inflammatory markers, complication rates, and patient satisfaction were compared.

Results: Versus the control group, the intervention group exhibited shorter times to first flatus, hospital stay, ambulation, and defecation (Cohen's d = 1.93, 1.24, 1.49, 1.57), higher postoperative PA, Hb, and ALB levels (Cohen's d = -0.63, -0.78, -0.70), lower CRP, IL-6, and TNF-α levels (Cohen's d = 0.48, 1.07, 0.90), and lower SAS and SDS scores (Cohen's d = 1.80, 0.89). At discharge, the intervention group exhibited a higher BMI (Cohen's d = -2.13), lower overall incidence of complications (OR = 6.00), and higher patient satisfaction (OR = 0.17) (p < 0.05).

Conclusion: The problem-oriented nursing model combined with EEN support improves nutritional status, accelerates recovery, and enhances postoperative rehabilitation in patients with stage II/III GC undergoing surgery.

Older cancer patients present a high risk of malnutrition and muscle loss, which can worsen outcomes and delay recovery. This study assessed whether combining nutritional risk screening tools with calf circumference (CC) measurements improves the prediction of hospital outcomes in older adults with solid tumors. A secondary analysis of 305 hospitalized cancer patients (mean age 68.2 ± 8.9 years; 59.3% male; 32.8% with gastrointestinal cancers) was conducted. Low CC was defined as ≤34 cm for men and ≤33 cm for women, with adjustments for body mass index ≥ 25 kg/m². Nearly 60% of patients had low CC. The Mini Nutritional Assessment-Short Form, particularly when combined with low unadjusted CC, showed the highest accuracy and sensitivity among the screening tools for predicting hospital stays of five days or more. In adjusted analyses, patients identified as being at nutritional risk and presented with low CC had approximately twice the odds of experiencing prolonged hospitalization. No significant association was found with hospital readmissions. These findings underscore the importance of integrating anthropometric measures like CC with established nutritional screening tools to better identify older cancer patients at risk for extended hospital stays.

Objective: This study aimed to evaluate the efficacy of a double-lumen biliary-enteric tube (DBET) for enteral nutrition (EN) in individuals with malignant obstructive jaundice (MOJ).

Methods: A retrospective cohort study was conducted using data from a prospectively maintained single-center database, including patients with MOJ. In the intervention group, DBET placement was performed concurrently with percutaneous transhepatic cholangiodrainage and biliary stenting, followed by postoperative EN (DBET-EN). In the control group, deep vein catheterization was undertaken after endoscopic biliary stenting, and parenteral nutrition (PN) was provided. A multivariable generalized linear model was used to assess the association between DBET-EN and 6-month mortality.

Results: A total of 74 patients were included in this study, comprising 28 patients in the intervention group (DBET-EN group) and 46 patients in the control group (PN group). Within the 6-month follow-up, 5 patients (17.9%) in the DBET-EN group and 20 (43.5%) in the PN group died. The multivariable generalized linear model demonstrated a significantly reduced 6-month mortality in the DBET-EN group compared to the PN group (adjusted odds ratio [OR]: 0.25, 95% CI: 0.08-0.81, P = 0.020). Secondary outcomes indicated that patients in the DBET-EN group had lower 9-month mortality rates and longer tube retention durations compared to the PN group (all adjusted P < 0.05). Postoperative liver function improved similarly in both groups. At 3, 6, and 9 months postoperatively, patient-generated subjective global assessment (PG-SGA) scores and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) scores were significantly higher in the DBET-EN group than in the PN group (P < 0.05).

Conclusion: The implementation of DBET for EN in patients in the advanced stage of MOJ proved to be a minimally invasive and safe intervention. It significantly improved patients' nutritional status and quality of life while reducing mortality.

Data supporting the safety and clinical efficacy of early oral feeding (EOF) after total gastrectomy are limited. The aim of this prospective randomized controlled study was to explore the safety and clinical efficacy of two early enteral nutrition approaches for gastric cancer patients after radical total gastrectomy. The EOF group had faster postoperative recovery of intestinal function than the enteral tube feeding (ETF) group. The times to first flatus and first defecation were shorter in the EOF group (p < 0.05). In addition, the EOF protocol effectively avoided abdominal distension (p < 0.05). The hospitalization cost of the EOF group was lower than that of the ETF group (p < 0.05). Moreover, oral nutrition satisfied the physiological need for oral intake. People were more satisfied with EOF (p < 0.01). Furthermore, it is worth noting that compared with ETF, EOF did not increase the risk of anastomotic complications such as leakage and bleeding. Most obviously, EOF not only avoided the risk of complications during tube insertion, but also avoided the discomfort experience of nasal feeding tube. In summary, compared with ETF, EOF promotes early bowel recovery effectively without increasing the risk of postoperative complications. It is safe and comfortable for gastric cancer patients undergoing radical total gastrectomy.

Gastric cancer (GC) is a malignant tumor with high morbidity and mortality rates worldwide. This study aimed to investigate the effects and mechanisms of action of didymin, a dietary flavonoid glycoside, on GC treatment. Human GC cell lines Hs-746T and AGS were used to assess the effects of didymin on cell viability, cell proliferation, and cell cycle. The results showed that didymin decreased the proliferative capacity of GC cells and blocked cell cycle. Didymin decreased wound healing, invasion, and migration capacities of GC cells. Mitochondrial reactive oxygen species (ROS) levels and mitochondrial membrane potentials were reduced in cells treated with didymin. Network pharmacology analysis revealed that the therapeutic effects of didymin on AGS cells were related to the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. In vivo mouse xenograft studies confirmed that didymin treatment decreased tumor cell proliferation, cell cycle protein levels, and Akt phosphorylation. The present study demonstrated that didymin regulates mitochondrial function and the PI3K/Akt pathway to inhibit cell proliferation and induce apoptosis in GC cells in vitro and in vivo. Therefore, didymin is a promising drug for the treatment of GC.
