Zinc plays a critical role in thyroid hormone metabolism and antioxidant defense, yet its relationship with thyroid cancer remains unclear due to limited and inconsistent evidence from predominantly cross-sectional studies. We conducted a large-scale retrospective cohort study using the TriNetX Research Network to examine the longitudinal association between zinc deficiency (ZD) and thyroid cancer risk over ten years. Among 96,497 propensity score-matched pairs of adults who underwent serum zinc measurements between January 2010 and December 2023, we classified patients as zinc-deficient (serum zinc below 70 μg/dL) or having normal zinc status (70-120 μg/dL), controlling for demographics, comorbidities, preexisting thyroid disorders, and laboratory parameters. While the overall cohort showed no significant association between ZD and thyroid cancer at 5 years (hazard ratio [HR]: 1.13, 95% confidence interval (CI): 0.93-1.37) or 10 years (HR: 1.12, 95% CI: 0.93-1.34), sex-stratified analyses revealed that women with ZD demonstrated significantly increased thyroid cancer risk at both 5 years (HR: 1.37, 95% CI: 1.09-1.72) and 10 years (HR: 1.38, 95% CI: 1.12-1.71), while men showed no association. These findings suggest that ZD may represent a sex-specific modifiable risk factor for thyroid cancer in women, warranting further mechanistic investigation.

This study explores the use of nutrition supplements by Jordanian cancer patients regarding symptoms of quality of life. It explores the prevalence of the use of nutrition supplements by cancer patients and the related demographic and disease-specific factors. A cross-sectional study was conducted on cancer patients at three major hospitals in Jordan. A total of 220 participants completed structured questionnaires. The EORTC QLQ-C15 scale was used to collect data on supplement usage patterns and quality of life. Chi-square tests and regression analysis were performed to assess the association between supplement use and QoL outcomes. Supplement use was noted in 65.9% of participants; the most used supplements were vitamin D, calcium, and omega-3. Supplement use was significantly associated with age, gender, income, and education level but showed a positive association between supplement use and improved QoL (p = 0.028). The findings suggest that the use of supplements is associated with improved quality of life among cancer patients in Jordan. It is important to consider integrating patient education and professional guidance regarding safe supplement use into cancer care. Further, longitudinal studies are needed to generalize these findings and to explore the long-term effect of supplements on QoL.

Malnutrition, including undernutrition and overnutrition, affects survival, treatment response, and quality of life in children with cancer. However, its prevalence, trajectory, and clinical impact remain underexplored. This non-randomized pilot feasibility study evaluated the feasibility of comprehensive nutritional data collection and documented nutritional status from diagnosis through treatment in 38 children (<18 years) with pediatric cancer or Langerhans Cell Histiocytosis in New Zealand (June 2022-September 2023). Anthropometric, biochemical, and clinical data were collected at diagnosis and four follow-up points. Micronutrient abnormalities, including excesses and deficiencies, were highly prevalent, peaking at 3 months post-diagnosis (95%) and declining by month 12 (55%). Patients experienced reduced linear growth (p = .013) and increasing BMI over time (p = .03). Micronutrient status was significantly associated with malnutrition risk scores (SCAN and STRONGkids; p < .001), BMI-for-age z-scores, and weight status (BMI-for-age percentiles). Treatment complications were associated with micronutrient status (p < .001), weight status (p = .016), and malnutrition risk scores (p < .001). Nutritional challenges in pediatric cancer extend beyond weight changes to include micronutrient imbalances and clinical consequences. Routine nutritional assessment and targeted interventions, such as dietary optimization, micronutrient supplementation, and physical activity programs, are essential to improving treatment tolerance, recovery, and long-term health outcomes.

Children with cancer frequently suffer from malnutrition caused by their disease and treatments. This study examines the rates of malnutrition, compliance with nutritional therapy, and its impact on nutritional status in pediatric cancer patients. This multicenter cross-sectional study was conducted between 2021 and 2023 at 12 pediatric hematology and oncology clinics. This study included 385 patients (aged 0.3-18 years) with leukemia-lymphoma and solid tumors that are currently on or had newly started oral nutritional supplement (ONS) treatment. Anthropometric measurements, mid-upper-arm-circumference (MUAC), body mass index (BMI), weight-for-age (WFA), were collected, and malnutrition risk was evaluated by the nutrition screening tool for childhood cancer (SCAN). Baseline WFA-based malnutrition was 31.0%, increasing to 38.5%, while SCAN≥3 was 83.8% decreasing to 72.4% at the sixth month. Malnutrition risk was more common in sarcoma and central nervous system tumor patients. ONS adherence decreased across all cancer types during the follow-up period. Adherent patients demonstrated higher BMI scores during the study period and MUAC z-scores in the last 2 months compared to the non-adherent group (P < 0.04). Our study demonstrates that the use of validated nutrition screening tools, together with adherence strategies, can lead to increased weight-for-age and lower malnutrition risk screening scores.

Sarcopenia, malnutrition, and frailty frequently coexist in older adults with cancer, adversely affecting treatment tolerance, functional independence, and survival. While comprehensive geriatric assessment (CGA) is the gold standard for frailty evaluation, its resource-intensive nature limits routine use, and simple tools are needed. This cross-sectional study included 291 patients aged ≥70 years with histologically confirmed cancer, evaluated at a oncology outpatient clinic between January and November 2024. Sarcopenia was defined according to EWGSOP2 criteria: handgrip strength (HGS) and skeletal muscle index (SMI) by bioelectrical impedance analysis (BIA). Nutritional status was assessed with the Mini Nutritional Assessment-Short Form (MNA-SF), and frailty was defined as G8 ≤ 14. Additional measures included SARC-F, Mini-Mental State Examination (MMSE), and Geriatric Depression Scale. The median age was 74 years, and 53% were male. Possible sarcopenia was identified in 39.5%, confirmed sarcopenia in 33.7%, severe sarcopenia in 26.8%. Nutritional risk was observed in 66.7%, and frailty in 44.7%. Frailty correlated strongly with nutritional status and moderately with muscle strength and mass. In multivariable analysis, low HGS, low SMI, nutritional risk, and depression independently predicted frailty. ROC analysis showed, G8 with HGS and nutritional assessment improved predictive accuracy. These findings highlight that simple measures enhance frailty detection and may support personalized care.

To analyze factors influencing iodine-131 (I-131) treatment efficacy in differentiated thyroid carcinoma (DTC). This retrospective study classified 299 patients with DTC into medium-low-risk and high-risk groups, assessing clinical data (preoperative stimulated thyroglobulin [ps-Tg], urinary iodine, gender, T stage, diet). Patients followed normal or iodine-restricted diets. Statistical analyses included t-tests, chi-squared tests and logistic regression. Medium-low risk and higher ps-Tg levels and urinary iodine concentrations correlated with less favorable outcomes (p < 0.001). High-risk patients showed significant differences in gender, T stage and ps-Tg level (p < 0.001). Multivariate analysis identified risk level, T stage and ps-Tg level as key prognostic factors (p < 0.001), with urinary iodine concentration having a minor effect (p = 0.003). Risk stratification, T stage and ps-Tg level were the primary prognostic determinants. Dietary interventions showed different effects in different risk-stratified patients, requiring individualized consideration. These findings emphasize the importance of comprehensive assessment in DTC management.
