e24042 Background: Cancer is 2nd leading cause of death (1 in every 5) in the United States followed by heart disease. Use of ketogenic diet (KD)- high-fat & low-carbohydrate diet, allows fatty acids to become the obligatory source of cellular energy which can help in decreasing the tumor cell growth. Aim of this study was to evaluate role of KD in different types of cancer. Methods: We performed a systematic review using PRISMA protocol to identify articles describing the role of the ketogenic diet in cancer patients in PubMed. Keywords like cancer, neoplasm, tumor, KD, and intermittent fasting (IF) were used & filters like full text, English, human, observational studies, & clinical trials (CTs) were applied between 2018-2022. Results: Of the 362 studies after using filters only 22 studies were CTs. Of these 22, 12 studies were excluded & 10 studies were included in this study. [Table 1] We found CTs describing role of KD, IF or standard diet (SD) in brain cancer, non-metastasized rectal cancer, high-grade glioma, head and neck squamous cell carcinoma, locally advanced and metastatic breast cancer, ovarian and endometrial cancer. KD was describes as an accompanying measure for patients undergoing standard-of-care therapy that helps to improve the quality of life, survival & acceptable safety and tolerability. KD may augment the antitumor effects of classic chemotherapy and radiotherapy. Conclusions: Role of KD is described in depth, but majority RCT results were heterogeneous in nature to provide quantitative measures of survival timeline, outcomes, & recovery. Thus, more human prospective studies are warranted to evaluate the therapeutic effectiveness & safety of KD.[Table: see text]

e20010 Background: For the year 2019, the United States age-adjusted rate of new Multiple Myeloma (MM) cases was 6.8 per 100,000 people and the age-adjusted death rate was 3 per 100,000 people. Vitamin D Deficiency (VDD) and associated complications are very common in MM patients. Aim of our study was to evaluate the prevalence and risk of VDD in patients with MM and VDD associated disability and mortality in the VDD patients. Methods: We performed a cross-sectional retrospective analysis of Nationwide Inpatient Sample data 2016-2018. Adults hospitalizations with MM were identified using ICD 10 code. Hospitalized patients were grouped into patients with VDD and without VDD. We ran chi square, unpaired-t test and mixed-effect survey logistic regression analysis to find out odds ratio and 95%CI showing outcomes of VDD in MM patients. Results: We found 330,175 hospitalizations with MM. Of these 11,480 were noted to be patients with VDD with higher prevalence (0.64% vs 0.37%) of and strong association (aOR:1.41, 95%CI:1.35-1.47) with MM in comparison without MM. Amongst MM, females [1.50, 1.49-1.51], black race [1.23, 1.22-1.24], urban teaching hospitals [1.22, 1.22-1.23], and hospitals in mid-west region [1.30, 1.29- 1.32] had higher prevalence odds of VDD compared with males, white race population, rural hospitals and hospitals in northeast region. (p<0.0001) Patients with VDD had higher prevalence and strong association with higher morbidity [5.1% vs 3.9%, 1.24,1.14-1.36; c-value=0.67], severe/extreme disability [77.2% vs 73.3%, 1.26, 1.20-1.33; c-value=0.73], and discharge to locations other than home [51.15% vs 45.69%, 1.29, 1.23-1.34; c-value=0.69] in comparison without VDD. (p<0.0001) [Table]. Conclusions: Significant poor outcomes warrant early identification of VDD and role of same hospitalization vitamin D replacement amongst MM patients with higher risk.
