RESUMO

Weight loss in patients with cancer is caused by cancer cachexia and chemotherapy-induced nausea and vomiting. Recent developments in antiemetic drugs have substantially improved nausea and vomiting, but this intervention did not reduce weight loss and other more severe side effects of chemotherapy, like anorexia, weakness, cough, dyspnea, hemoptysis, and pain. This study aimed to investigate the effects of nutrition intervention with a food supplement, during chemotherapy in patients with advanced nonsquamous non-small cell lung cancer (NSCLC). Patients received individualized nutrition counseling by a registered dietitian and were provided with oral supplements of Texidrofolico® for 90 days. Bodyweight and the mentioned other side effects were evaluated at baseline and after 90 days of intervention. To assess the effects of this dietary supplement, a total of 30 patients were retrospectively enrolled as controls, and the bodyweight and change in side effects of chemotherapy were compared with those observed in 30 Texidrofolico®-treated patients. After 90-day intervention, by oral supplement of Texidrofolico®, the patients, during the course of cytotoxic chemotherapy, showed an improved quality of life and not significant weight and BMI loss respect the control group. Furthermore, the number of patients, treated with Texidrofolico® who maintained or increased their body weight, after 90 days of treatment was significantly higher than in the control group. The effects of treatment with the food supplement have also been studied from a metabolic point of view. It was possible to find that one of the known markers of tumor growth, plasma polyamines, was reduced after the treatment. A possible relationship between these biogenic amines and the folate cycle is discussed. In conclusion, early intensive nutrition intervention with oral supplements of Texidrofolico® during chemotherapy of NSCLC patients prevents weight loss and it is beneficial for their quality of life.

RESUMO

Introduction The aim of the present study was to survey the protective effect of pretreatment with Persian honey on amelioration of side effects of chemotherapy and ischemia/reperfusion induced testicular injury. Materials and methods Forty adult's male wistar rats were divided into four groups of ischemia-reperfusion (IR), honey + ischemia-reperfusion (HIR), Busulfan (B) and Busulfan intraperitoneally+ honey (BH). The seminiferous tubules were rated for their modified spermatogenesis index (SI) by Johnsons score. Detection of single- and double-stranded DNA breaks at the early stages of apoptosis was performed using the in-situ cell death detection kit. Total serum concentration of Follicle-stimulating hormone (FSH) , Luteinizing hormone (LH) and testosterone was measured using ELISA. All data were expressed as mean ± SD and significance was set at p≤0.05. Results Honey improved SI in the HIR and BH groups and serum levels of FSH and LH in the BH and HIR groups (p<0.001). Also, serum levels of testosterone were significantly higher in BH and HIR groups. But, apoptotic cells in IR and B groups significantly increased (p<0.001), while in HIR and BH groups, the number of apoptotic cells decreased and the positive cells of TUNEL (TdT-mediated dUTP-X nick end labelling) staining were detected in spermatocytes and spermatid. Discussion Pretreatment with honey protect testis against chemotherapy and testicular IR injury, increase FSH and LH and testosterone and decrease the cellular damage and apoptosis. Honey can decrease the side effects of chemotherapy on reproductive system and prevent sterility.

RESUMO

An elemental diet (ED) has been reported to reduce oral mucositis and dermatitis induced by chemotherapy. However, its molecular mechanism of action as an anti­inflammatory agent is still unknown. The aim of the present study was to clarify whether ED confers its anti­inflammatory action via reduction of pro­inflammatory cytokine production in keratinocytes in vivo and in vitro. We evaluated the efficacy of ED in the treatment of 5­fluorouracil (5­FU)­induced dermatitis of nude mice, and examined the expression of pro­inflammatory cytokines such as tumor necrosis factor­α (TNF­α), interleukin (IL)­1ß and IL­6 using immunohistochemistry. Moreover, we assessed the expression and production of these pro­inflammatory cytokines by western blotting and ELISA assays, respectively, in immortalized human keratinocyte cell line, HaCaT. Furthermore, we investigated the effect of ED on a major inflammation­related factor, nuclear transcription factor­κB (NF­κB), since it controls many genes involved in the inflammation pathway. Our results indicated that ED reduced the expression of TNF­α, IL­1ß and IL­6. It also inhibited the nuclear transition of p65 NF­κB, which is known to regulate inflammatory cytokine expression in keratinocytes suffering from 5­FU­induced dermatitis. In addition, ED reduced the production of TNF­α, IL­1ß and IL­6 in HaCaT cells. Moreover, ED attenuated 5­FU­induced transcriptional activation of NF­κB. These findings revealed that ED suppresses the expression of pro­inflammatory cytokines by suppressing NF­κB in keratinocytes, suggesting the potential usefulness of ED in the treatment of various inflammatory diseases of the dermal region.

RESUMO

BACKGROUND: Modifiable lifestyle factors, such as diet quality, could reduce inflammation and improve quality of life (QOL) in breast cancer survivors, but data are inconclusive. OBJECTIVE: To determine whether diet quality, as measured by Healthy Eating Index-2010 (HEI-2010) score, is associated with inflammation, health status, or functional outcomes affecting QOL in survivors of early-stage breast cancer. DESIGN: This is a cross-sectional, secondary analysis of baseline data collected from breast cancer survivors after completion of primary therapy and before random assignment to a pilot nutritional intervention aimed at reducing side effects of aromatase inhibitor treatment. PARTICIPANTS/SETTING: Participants were 44 postmenopausal women with stage I to III endocrine receptor-positive breast cancer receiving outpatient care at a midwestern cancer center between November 2011 and October 2013. MAIN OUTCOME MEASURES: Primary outcomes were serum proinflammatory cytokines (interleukin-6 [IL-6], IL-17, and tumor necrosis factor-α receptor 2 [TNFR-2]). Secondary outcomes included QOL measured by the Stanford Health and Disability Questionnaire and the Functional Assessment of Cancer Therapy-Breast with Endocrine Subscale. STATISTICAL ANALYSES PERFORMED: Pearson correlation coefficients (r) and linear regression models were used to evaluate the relationship of dietary variables with inflammatory cytokines and QOL measures. RESULTS: A higher overall HEI-2010 score (healthier diet) was associated with lower IL-6 (r=-0.46; P=0.002) and TNFR-2 (r=-0.41; P=0.006); however, associations were attenuated by body mass index (BMI) (IL=6 [r=-0.26; P=0.10]; TNFR-2 [r=-0.30; P=0.06]). In women with prior chemotherapy, a higher HEI-2010 score was strongly associated with lower IL-6 (r=-0.67; P=0.009) and TNFR-2 (r=-0.59; P=0.03) after BMI adjustment. There were no significant correlations between HEI-2010 score and QOL measures after adjustment for BMI. CONCLUSIONS: These data suggest the need for more rigorous investigation into the relationship of diet quality, BMI, and inflammation in breast cancer survivors.
