Internal Medicine, East Africa

Promoting best practice in the management of a cancer patient is rooted in the application of new knowledge derived through various sources including population science, laboratory advances, and translational research. Ultimately, the impact of these advances depends on their application at the patient’s bedside. A close collaboration between the oncologist and the pathologist is critical in underwriting progress in the management of the cancer patient. Recent advancements have shown that more granular characteristics of the tumor and themicroenvironment are defining determinants when it comes to disease course and overall outcome. Whereas, histologic features and basic immunohistochemical characterization were previously adequate …

Integrated Multilayer Omics Reveals The Genomic, Proteomic, And Metabolic Influences Of Histidyl Dipeptides On The Heart, Keqiang Yan, Zhanlong Mei, Jingjing Zhao, Md Aminul Islam Prodhan, Detlef Obal, Kartik Katragadda, Benjamin Doelling, David Hoetker, Dheeraj Kumar Posa

Internal Medicine, East Africa

Background: Histidyl dipeptides such as carnosine are present in a micromolar to millimolar range in mammalian hearts. These dipeptides facilitate glycolysis by proton buffering. They form conjugates with reactive aldehydes, such as acrolein, and attenuate myocardial ischemia-reperfusion injury. Although these dipeptides exhibit multifunctional properties, a composite understanding of their role in the myocardium is lacking.

Methods and Results: To identify histidyl dipeptide-mediated responses in the heart, we used an integrated triomics approach, which involved genome-wide RNA sequencing, global proteomics, and unbiased metabolomics to identify the effects of cardiospecific transgenic overexpression of the carnosine synthesizing enzyme, carnosine synthase (Carns), in …

Perceived Barriers To Peritoneal Dialysis Among Kenyan Nephrologists: A Cross-Sectional Descriptive Study, Saleem Abdul Karim Sokwala, John Otieno Odhiambo, Ahmed Sokwala

Internal Medicine, East Africa

Background: Peritoneal dialysis (PD) is a well-recognized technique of renal replacement therapy (RRT), with similar efficacy as well as survival outcomes as hemodialysis (HD). Despite its advantages including prolonged preservation of residual renal function, potentially lower cost and advances with automated techniques, and commercialization of more biocompatible solutions, the overall prevalence of patients treated with PD is still very low in developed countries and even more so in Africa and low-middle income countries like Kenya. According to our knowledge, no local studies have been done on prevalence of peritoneal dialysis or on potential barriers to utilization of PD as an …
