Background: Breast cancer patients are at risk of acute decompensated heart failure (ADHF) and protein-energy malnutrition (PEM) due to chemoradiation effects or cancer itself. There are no existing studies on the impact of PEM on breast cancer patients hospitalized for ADHF. This study aims to evaluate the effects of PEM on breast cancer patients admitted for ADHF.

Methods: Using the 2020 US National Inpatient Sample (NIS), our study analyzed breast cancer patients aged 18 and older. A multivariate logistic and linear regression analysis determined the odds ratio for various outcomes. The primary outcome was inpatient mortality among patients hospitalized for ADHF based on the presence or absence of PEM, while secondary outcomes included cardiogenic shock, anemia, and total hospital charges.

Results: Thirty thousand five hundred and fifty-five (30,555) patients were identified, predominantly female (99%) and Caucasian (71.4%). Among them, 6.07% were diagnosed with concurrent PEM. PEM was associated with higher in-hospital mortality risk (aOR 2.61), increased cardiogenic shock (aOR 3.17), anemia (aOR 1.43), more extended hospital stays (b 2.09), and higher hospital charges (average $28,285).

Conclusions: The findings indicate that comorbid PEM is associated with increased risks of in-hospital mortality, anemia, cardiogenic shock, prolonged hospital stays and increased overall hospital costs among breast cancer patients admitted for ADHF.

High sodium diets have been shown to promote stomach colonization and the induction of tissue damage by Helicobacter pylori (H. pylori), a risk factor for gastric cancer. Among American Indians in the Southwest, where the H. pylori prevalence is 60%, the association between diet and H. pylori infection has not been studied. We conducted a cross-sectional pilot study with 93 adults (51%, 18-44 years, 73% female) in the Navajo Nation to assess their diet with self-administered food questionnaires and to detect H. pylori from stool samples using droplet digital PCR. Three diet patterns were identified using Principal Component Analysis: 1) Western, 2) Soups and Mixed Dishes, and 3) Fruits and Vegetables. Participants in the highest and middle tertiles of the Soups and Mixed Dishes pattern scores had higher odds of having H. pylori (OR_Highest=5.59, 95% CI, 1.50-23.70; OR_Middle=3.48, 95% CI, 1.08-12.32) than those in the lowest tertile. This positive association may be linked to the sodium content of foods in this diet pattern. Soups and Mixed Dishes may contribute to H. pylori infection and may be incorporated in nutrition education for individuals positive for H. pylori infection in the Navajo Nation.

Vitamin D insufficiency has been frequent in women with breast cancer (BC), as well as impaired muscle strength (MS), and a possible relationship between these conditions has been investigated in different populations, except in women with BC. This study aimed to analyze the association between serum vitamin D levels and MS in women with BC. Observational cross-sectional study carried out with adult women with BC, without metastasis/recurrence, with up to 12 months of diagnosis. Serum 25(OH)D concentration was categorized as insufficient (<30 ng/mL) or sufficient (≥30 ng/mL). MS was assessed by the Handgrip Strength test and divided into strength tertiles of the population itself: 1st tertile (6-21 kg), 2nd tertile (22-26 kg), and 3rd tertile (27-39 kg). Adjusted multinomial logistic regression models verified the association of serum vitamin D levels in MS tertiles, with a significance of 5%. A total of 151 women were evaluated. Most women had insufficient levels of vitamin D (70%). Insufficient serum vitamin D levels were associated with the 1st and 2nd tertile of MS (odds ratio [OR]: 5.74, 95% confidence interval [CI]: 1.77-18.64, P = 0.004; OR: 4.48, 95% CI: 1.34-14.97, P = 0.015, respectively). Serum vitamin D insufficiency incresed the probability to present lower tertiles of MS in women with BC.

Background: This study aimed to elucidate the causal relationship between Omega-6/Omega-3 fatty acid ratio and the risk of lung cancer by using Mendelian randomization (MR) analyses.

Methods: Omega-6/Omega-3 fatty acid ratio data from the IEU database and lung cancer patient data from the International Lung Cancer Consortium were collected for this MR analyses. Single nucleotide polymorphisms (SNPs) associated with Omega-6/Omega-3 fatty acid ratio were collected as instrumental variables (IVs) with criteria of P < 5E-8, linkage disequilibrium R² > 0.001 and clump distance < 10,000 kb. We used the inverse variance weighted (IVW) method as the primary method of MR analyses to evaluate the causal relationship between Omega-6/Omega-3 fatty acid ratio and lung cancer risk. Heterogeneity of the analyses was assessed by Cochran's Q test. Horizontal pleiotropy was evaluated by the intercept with the MR-Egger test.

Results: 28 SNPs related to Omega-6/Omega-3 fatty acid ratio were selected as IVs in total. The MR analyses results showed that higher Omega-6/Omega-3 fatty acid ratio was associated with lower risk of lung cancer (P = 0.009). No statistical significance was observed for MR-Egger and simple mode methods (P > 0.05). No significant horizontal pleiotropy was detected by MR-Egger regression test (P = 0.73). Conclusion: Higher Omega-6/Omega-3 fatty acid ratio was associated with lower lung cancer risk.

Serum zinc and selenium concentrations might be altered by various disease conditions including malignancies. We aimed to prospectively investigate the serum levels of both elements in pediatric cancers. Children <18 years with newly diagnosed cancers were eligible. Data regarding demographics, histopathological diagnoses, tumor sites, disease extent, treatments given and outcomes were recorded. Serum samples were obtained at diagnosis and in the 3-4 months after diagnosis to determine the serum concentrations of zinc and selenium using "inductively coupled plasma mass spectrometry" (ICP-MS) method. Serum levels were compared to normal references and also in the subgroups according to tumor types, tumor sites and disease extent. Eighty-one children were included (Male/female: 50/31, median age 7.5-years). Twenty-five patients had lymphomas and 56 had solid tumors. For all patients, median serum levels of zinc and selenium were 69.5 mcg/dL and 114.3 mcg/L, respectively, which were comparable to normal reference values. In patients with lymphomas, mean and median initial zinc levels were significantly lower compared to solid tumors, which increased following treatment. No significant difference was detected in initial selenium concentrations of all patients and also in the subgroups. In the 3.-4. months following treatment, selenium levels decreased significantly in solid tumors. No significant difference was detected in the survival rates according to Zn and Se levels. Lower zinc levels at diagnosis in lymphomas was remarkable. The decline in Se levels after treatment may reflect the selenophilic nature of solid tumors and could also be linked to reduced appetite and dietary intake. Suppression of hepatic biosynthesis of selenoprotein by some chemotherapeutics might also contribute to diminished selenium levels after treatment. Further studies are needed to explore the implications of deficiencies in both elements.

The recent study by Lughmani et al. demonstrated that a 30-day regimen of 23:1 intermittent fasting combined with a ketogenic diet significantly elevated serum AMPK levels and reduced CA 15-3 in breast cancer patients undergoing chemotherapy. While these findings highlight the potential of metabolic interventions to modulate key signaling pathways, important questions remain regarding clinical translation and patient heterogeneity. First, the impact of fasting and ketogenic strategies on chemotherapy-related toxicity, treatment tolerability, and quality of life was not evaluated; integrating standardized toxicity grading (e.g., CTCAE v5.0), patient-reported outcome measures, and chemotherapy dose intensity metrics could determine whether AMPK activation confers meaningful protective benefits. Second, breast cancer subtypes exhibit distinct metabolic dependencies and AMPK pathway alterations; prespecifying subgroup analyses by receptor status and correlating intratumoral AMPK activity with molecular subtype would inform personalized dietary adjuncts. Addressing these dimensions will be pivotal for validating intermittent fasting plus ketogenic diets as safe, tailored adjuncts to standard chemotherapy.

Background: Cancer survivors face an elevated risk of mortality, and changes in body mass index (BMI) may play a critical prognostic role. This study examined BMI variations during early adulthood and recent years in relation to cancer-specific mortality and all-cause mortality.

Methods: Data were drawn from the National Health and Nutrition Examination Survey. Statistical models were applied to evaluate associations, dose-response relationships, and threshold effects.

Results: Among 2,024 cancer survivors, recent BMI increases were significantly associated with reduced cancer and all-cause mortality, whereas earlier BMI changes showed weaker associations. Compared with those in the lowest tertile, those with greater recent BMI increases had a 24%-44% lower risk of cancer mortality (P for trend = 0.016) and a 34%-45% lower risk of all-cause mortality (P for trend < 0.001). A non-linear association was identified, with a 5% BMI increase as the threshold; each 1% gain below this threshold was linked to a 4% mortality risk reduction (p < 0.001). Joint analysis revealed that a high early BMI combined with a ≥ 5% recent BMI increase significantly reduced mortality risk.

Conclusions: Moderate recent weight gain may improve survival among cancer survivors, underscoring the importance of individualized weight management strategies.

The SARS-CoV-2 virus has been the subject of study by several researchers worldwide since 2020; however, there are points to be clarified. This study aimed to analyze the clinical and nutritional aspects of hospitalized cancer and non-cancer pediatric patients and the association with COVID-19 outcomes. This is a cohort study of hospitalized children and adolescents with a laboratory diagnosis of COVID-19. Patients were assessed according to the presence or absence of previous oncological diseases. Sociodemographic, clinical and nutritional data were investigated during the course of the infection. Outcomes included Intensive Care Unit (ICU) admission, longer length of stay (14 days), criticality, and death. Oncological disease was found in 16 (19.3%) patients, most of whom had B-type acute lymphoid leukemia. In Poisson regression, adjusted for age and comorbidity, an association was found between oncological disease and length of stay ≥14 days (RR 4.30; 95% CI 1.46 - 15.6; p = 0.013), COVID-19 criticality (RR 3.82; 95% CI 1.66 - 30.9; p = 0.010) and death (RR 3.42; 95% CI 0.94 - 9.96; p = 0.035). The research revealed that cancer patients had longer hospital stays, were more likely to have the severe form of COVID-19, and had a 3.42 times greater risk of dying.

Background: Colorectal cancer (CRC) is a prevalent global malignancy with substantial morbidity and mortality. Accurate prognostic evaluation is essential in CRC patient management. This study investigates the prognostic significance of red blood cell count (RBC) and Onodera's prognostic nutritional index (OPNI) in resectable CRC patients.

Methods: A retrospective analysis of 210 CRC patients undergoing radical resection (January 2015-January 2017) assessed clinical and hematological factors, including RBC, albumin, hemoglobin, and OPNI. A novel comprehensive biomarker, R-OPNI, combining preoperative RBC with OPNI, was introduced. Correlations with patient survival were analyzed, and R-OPNI's independent prognostic value was assessed through univariate and multivariate Cox models. Predictive ability was compared to other factors using the receiver operating characteristic (ROC) method.

Results: Higher RBC levels (≥ 3.9 × 10¹²/L) and elevated OPNI were associated with significantly improved overall survival. Lower R-OPNI scores (0 or 1) indicated notably poorer survival. Multivariate analysis confirmed R-OPNI's independent prognostic significance (HR: 0.273, 95% CI: 0.098-0.763, p = 0.013). R-OPNI (AUC = 0.732) demonstrated superior predictive value compared to individual prognostic factors.

Conclusion: R-OPNI emerges as a robust, independent prognostic predictor for resectable CRC patients, emphasizing the importance of assessing preoperative nutritional status.

There is inconclusive evidence on the role of dietary intake of vitamin B₁₂ in cancer. We evaluated the association between vitamin B₁₂ intake and cancer risk in a hospital-based case-control study, comprising 3,758 cancer cases and 2,995 controls in Vietnam. Vitamin B₁₂ intake was derived from the validated food frequency questionnaire. Unconditional logistic regression model was used to calculate the odds ratios (ORs), and respective 95% confidence intervals (CIs) for the association between vitamin B₁₂ and cancer risk. There was a U-shaped association between vitamin B₁₂ intake and overall risk of cancer. Individuals with intakes lower than the median intake had a 6% (OR = 1.06, 95% CI: 0.86-1.31)-107% (OR = 2.07, 95% CI: 1.58-2.71), increased risk of cancer (P_trend<0.001), whereas those with higher intakes than the median intake had a 20% (OR = 1.20, 95% CI: 0.97-1.48)-52% (OR = 1.52, 95% CI: 1.22-1.89) increased risk of cancer (P_trend<0.04). The excess risk of cancer associated with low intakes of vitamin B₁₂ was observed among esophageal, lung, and breast cancer patients, whereas with high intakes of vitamin B₁₂ among gastric cancer patients. In summary, a U-shaped association between vitamin B₁₂ intake and increased cancer risk was observed in the Vietnamese population.
