Cardiac dysfunction and their determinants in patients treated for breast cancer and lymphoma: A cardio-oncology center experience.

OBJECTIVE: Cancer and cardiovascular diseases both have adverse effects on each other. We aim in the current study to investigate cardiac dysfunction including its prevalence, and associated factors in patients treated for breast cancer and lymphoma in a unique cardiac oncology center. METHODS: A single-center retrospective study included 180 patients with cancer breast and lymphoma who presented and were treated at our oncology center from January 2019 to February 2022. RESULT: Out of 180 consecutive patients, 155 patients (86 %) were diagnosed with cancer breast and 25 patients (14 %) were diagnosed with lymphoma. Patients with lymphoma were older age, less obese, and showed more prevalence of diabetes mellitus (DM) (P = 0.026, 0.05, and 0.04 respectively). They also showed more post-therapy left ventricular (LV) dilatation and lower values of global longitudinal strain (GLS); however, they did not develop more LV dysfunction compared to cancer breast patients. Moreover, lymphoma patients showed poor in-hospital outcomes (P = 0.04, 0.001, and 0.015 for infection, pericardial effusion, and mortality respectively). Cancer therapy-related cardiac dysfunction (CTRCD) was observed in 41 patients (23 %) of our population. The independent predictors of CTRCD in the current study were DM, low body mass index (BMI), and the use of trastuzumab. CONCLUSIONS: Some patients treated for breast cancer and lymphoma develop LV dysfunction. Lymphoma patients showed more subclinical LV dysfunction and poor in-hospital outcomes compared to patients with cancer breast. DM, low body mass index (BMI), and the use of trastuzumab were the independent predictors of cardiac dysfunction among our patients.

Impact of green antioxidants on decreasing the aflatoxins percentage in peanut oil seed (Arachis hypogaea L.) during storage.

The present study conducted an experimental investigation to impede the degradation of peanut (Arachis hypogaea L.) seeds and enhance their quality while being stored. The efficacy of eco-friendly chemicals such as ascorbic acid, salicylic acid, acetic acid, and propionic acid in seed preservation was evaluated over a period of six months. After a period of six months of storage in a greenhouse, an examination was conducted on peanut seeds that had undergone treatment. Rhizoctonia was observed after Cephalothorax, whereas Aspergillus, Fusarium, and Penicillium were the prevailing fungi throughout the storage period. The optimal outcomes were obtained from the conversion of acetic acid to propionic acid. The study observed a decline in seed oil, protein, carbohydrates, germination percentage, energy, index, length, vigour index, dead and rotten seeds, rotted seedlings, and surviving healthy seedlings, with an increase in storage duration ranging from zero to six months. The application of 100% propionic acid to peanut seeds throughout the storage duration resulted in decreased occurrences of deceased seeds, decaying seeds, and deteriorated seedlings. Peanut seeds that underwent treatment with green chemical agents of moderate and high intensity were found to be free of aflatoxin B1. The highest levels of chlorophylls a and b, carotenoids, and total phenols were observed in seeds stored in greenhouses and treated with 100% propionic acid and acetic acid extract. The application of propionic acid 100%, acetic acid 100%, salicylic acid 4 g/l and ascorbic acid 4 g/l proved to be the most effective treatments for peanut seeds, exhibiting the lowest total aflatoxin level of 0.40. The correlation coefficient between shoot fresh weight and shoot dry weight was found to be 0.99, whereas the correlation coefficient between root dry weight and shoot length was 0.67. The seed chemical analysis, seedling characteristics, and germination characteristics were subjected to clustering analysis, resulting in the formation of two distinct groups. The first group consisted of germination percentage and energy levels across all time points (0-6 months), while the second group consisted of the remaining characteristics. The findings of this research propose the utilisation of 100% propionic acid as a viable method for preserving peanut seeds and preventing their deterioration during storage. The application of 100% acetic acid has been found to be effective in enhancing the quality of seeds and minimising losses.
