Countries with demographics and lifestyle similar to KSA may gain insights from this review to shape their policies and procedures. © European Association for Predictive, Preventive and Personalised Medicine (EPMA) 2019.Aim and background Colon and rectum (colorectal) cancer cause substantial mortality and morbidity worldwide. The management and control of a complex disease such as cancer cannot rely on the old strategy of "one disease one medicine" and must make a transition into new-age practices involving predictive, preventive, and personalized medicine (PPPM) at its core. Adoption of PPPM approach to cancer management at the policy level requires quantification of cancer burden at the country level. For this purpose, we examine the burden of colorectal cancer in 185 countries in 2018. Based on results, we discuss the opportunities presented by PPPM and challenges to be encountered while adopting PPPM for the treatment and prevention of colorectal cancer. Data and methods Age- and sex-wise estimates of colorectal cancer were procured from the GLOBOCAN 2018. The country- and region-wise burden of colorectal cancer in 185 countries was examined using all-age and age-standardized incidence and mortality estimates. Human devtes exhibited nonlinear association with HDI, whereas MIR was negatively associated with HDI. Conclusion Colorectal cancer causes a substantial burden worldwide and exhibit a positive association with the socioeconomic status. With the aid of improving screening modalities, preventable nature of the disease (due to dietary and lifestyle risk factors) and improving treatment procedures, the burden of CRC can largely be curtailed. The high burden of CRC in developing countries, therefore, calls for effective prevention strategies, cost-effective screening, and early-stage detection, cost-effective predictive, and personalized treatment regime. © European Association for Predictive, Preventive and Personalised Medicine (EPMA) 2019.Background Ubiquitination is an important molecular event in lung squamous cell carcinoma (LSCC), which currently is mainly studied in nonsmall cell lung carcinoma cell models but lacking of ubiquitination studies on LSCC tissues. Here, we presented the ubiquitinated protein profiles of LSCC tissues to explore ubiquitination-involved molecular network alterations and identify abnormally ubiquitinated proteins as useful biomarkers for predictive, preventive, and personalized medicine (PPPM) in LSCC. Methods Anti-ubiquitin antibody-based enrichment coupled with LC-MS/MS was used to identify differentially ubiquitinated proteins (DUPs) between LSCC and control tissues, followed by integrative omics analyses to identify abnormally ubiquitinated protein biomarkers for LSCC. Results Totally, 400 DUPs with 654 ubiquitination sites were identified,, and motifs A-X (1/2/3)-K* were prone to be ubiquitinated in LSCC tissues. Those DUPs were involved in multiple molecular network systems, including the ubiquitin-proteasone analyses revealed that VIM and MRP1 were involved in multiple crucial biological processes and pathways. Further, TRIM2 and NEDD4L were predicted as E3 ligases to regulate ubiquitination of vimentin and MRP1, respectively. Conclusion These findings revealed ubiquitinomic variations and molecular network alterations in LSCC, which is in combination with multiomics analysis to identify ubiquitination-related biomarkers for in-depth insight into the molecular mechanism and therapeutic targets and for prediction, diagnosis, and prognostic assessment of LSCC. © The Author(s) 2020.Background Vitamin D deficiency is associated with the incidence and prevalence of a variety of neurologic disorders, including multiple sclerosis. However, available studies to date have not provided convincing evidence that vitamin D treatment improves fatigue and life quality in patients with multiple sclerosis. Aim To assess the relationship of vitamin D deficiency with health-related quality-of-life issues and fatigue in multiple sclerosis patients. Methods Vitamin D3 levels were measured in 149 multiple sclerosis patients. In patients with lower than 30 ng/mL levels, vitamin D was administered. Fatigue and health-related quality of life scores were measured at baseline and months 1, 3, 6, and 12 after the beginning of vitamin D3 administration. Results Among 149 patients, 90% were vitamin D deficient. After vitamin D supplementation, health-related quality of life and fatigue scores improved significantly. There was a direct association between health-related quality of life with absence of fatigue and vitamin D status at the end of study. Conclusion The 90% frequency of multiple sclerosis patients with vitamin D deficiency, together with the significant association of vitamin D status with the absence of fatigue and improved physical and functional well-being, points to vitamin D supplementation as a potential therapy to enhance the patient's quality of life. Relevance of the article for predictive preventive and personalized medicine This article emphasizes that vitamin D supplementation can improve clinical outcome in multiple sclerosis patients providing immune modulation and neuroprotection. Identification and correction of vitamin D deficiency has the potential to treat the related quality of life in patients with multiple sclerosis. © European Association for Predictive, Preventive and Personalised Medicine (EPMA) 2019.Background Critical limb ischemia (CLI) is a severe stage of peripheral arterial disease and has a substantial disease and economic burden not only to patients and families, but also to the society and healthcare systems. We aim to develop a personalized prediction model that utilizes baseline patient characteristics prior to CLI diagnosis to predict subsequent 1-year all-cause hospitalizations and total annual healthcare cost, using a novel Bayesian machine learning platform, Reverse Engineering Forward Simulation™ (REFS™), to support a paradigm shift from reactive healthcare to Predictive Preventive and Personalized Medicine (PPPM)-driven healthcare. https://www.selleckchem.com/products/iberdomide.html Methods Patients ≥ 50 years with CLI plus clinical activity for a 6-month pre-index and a 12-month post-index period or death during the post-index period were included in this retrospective cohort of the linked Optum-Humedica databases. REFS™ built an ensemble of 256 predictive models to identify predictors of all-cause hospitalizations and total annual all-cause healthcare costs during the 12-month post-index interval.
