The use of big data is in its first years of entering the medical world. Big data research enables analysis of very large volumes of data, identifying patterns and findings which traditional statistical methods cannot handle. The diagnosis of colorectal cancer is often missed due to people's non-adherence to the occult fecal blood screening tool. We describe the case of a patient that led to the development of a novel big data algorithm to diagnose colorectal cancer. A 70 year old, previously healthy man, was diagnosed with metastatic colorectal cancer and succumbed to his illness...

Patient-derived cancer organoid culture is an important live material that reflects clinical heterogeneity. However, the limited amount of organoids available for each case as well as the considerable amount of time and cost to expand in vitro makes it impractical to perform high-throughput drug screening using organoid cultures from multiple patients. Here, we report an advanced system for the high-throughput screening of 2427 drugs using the cancer tissue-originated spheroid (CTOS) method. In this system, we apply the CTOS method in an ex vivo platform from xenograft tumors, using machines to handle CTOSs and reagents, and testing a CTOS reference panel of multiple CTOS lines for the hit drugs...

OBJECTIVES: Evidence-based clinical practice guidelines (CPGs) for the treatment of pneumonia and sepsis have existed for many years with multiple studies suggesting improved patient outcomes. Despite their importance, little is known about variation in emergency department (ED) adherence to these CPGs. Our objectives were to estimate variation in ED adherence across CPGs for pneumonia and sepsis, and identify patient, provider, and environmental factors associated with adherence. METHODS: Design: Multicenter retrospective study using standard medical record review methods...

Hit, Lead & Candidate Discovery After acetylcholine is released into the synaptic cleft, it is reabsorbed or deactivated by acetylcholinesterase (AChE). Studies on Alzheimer's disease (AD) in the mid-20th century proved that cognitive dysfunctions are associated with cholinergic neurotransmission. Drugs, such as tacrine, rivastigmine, donepezil, and galantamine are known as acetylcholinesterase inhibitors. However, these drugs have limited use in advanced AD and dementia. Recently, the anticholinesterase activity of various heterocyclic-framed compounds, including piperazine derivatives, has been investigated, and compounds with similar effects to known drugs have been identified...

BACKGROUND: Eczema is a common, chronic, inflammatory skin condition that is frequently associated with atopic conditions, including asthma. Leukotriene receptor antagonists (LTRAs) have a corticosteroid-sparing role in asthma, but their role in eczema remains controversial. Currently available topical therapies for eczema are often poorly tolerated, and use of systemic agents is restricted by their adverse effect profile. A review of alternative treatments was therefore warranted. OBJECTIVES: To assess the possible benefits and harms of leukotriene receptor antagonists for eczema...

Preclinical Research & Development Appropriate translation and determination of the maximum recommended starting dose in human is a vital task in new drug development and research. Allometric scaling is the most frequently used approach for dose extrapolation based on normalization of dose-to-body surface area. Misinterpretation of allometric dose conversion and safety factor application can lead to major problems in calculating maximum recommended safe starting dose in first-in-human clinical trials. Therefore, dose translation always necessitates careful consideration of body surface area, pharmacological, physiological and anatomical factors, pharmacokinetic parameters, metabolic function, receptor, and life span...

PURPOSE: Glenoid fractures occur as a result of direct impact of the humeral head against the glenoid rim following high-energy trauma. They frequently involve one-third of the glenoid surface with an oblique fracture rim from 2 to 6-7 o'clock, and they must not be confused with bony Bankart lesions. In medium-age patients, they are frequently associated with acute cuff tear while in older patients with chronic cuff tear: These conditions increase the instability of the shoulder if not treated...

Despite hydromorphological pressure assessment is required by the European Water Framework Directive (WFD), there is not one commonly accepted method for this purpose. The extent of habitat alteration and naturalness loss is a major issue especially for heavily modified water bodies (HMWBs) in terms of their maximum ecological potential designation. In this research, a broadly used methodology in Central and Northern Europe, Lake Habitat Survey (LHS), is tested for the first time in Greece in two natural urban shallow lakes to estimate the extent of habitat modification and hydromorphological alteration...

Aminochrome induces neurotoxic alpha-synuclein oligomer formation relevant to the etiology of Parkinson's disease. Oxidative stress produces aminochrome from dopamine, but conjugation with glutathione catalyzed by glutathione transferase M2-2 significantly decreases aminochrome-induced toxicity and alpha-synuclein oligomer formation. Notably, in the presence of the aminochrome-glutathione conjugate, previously unknown species of alpha-synuclein oligomers are formed. These aminochrome-glutathione oligomers of alpha-synuclein differ from formerly characterized oligomers and (i) have high molecular weight, and are stable and SDS-resistant, as determined by the Western blot method, (ii) show positive NBT-quinone-protein staining, which indicates the formation of alpha-synuclein adducts containing aminochrome...

Elena F Jacobson, Emmanuel S Tzanakakis
PURPOSE OF REVIEW: Ever since the reprogramming of human fibroblasts to induced pluripotent stem cells (hiPSCs), scientists have been trying to determine if hiPSCs can give rise to progeny akin to native terminally differentiated cells as human embryonic stem cells (hESCs) do. Many different somatic cell types have been successfully reprogrammed via a variety of methods. In this review, we will discuss recent studies comparing hiPSCs and hESCs and their ability to differentiate to desired cell types as well as explore diabetes disease models...

Comprehension of physiology is essential for development of clinical reasoning. However, medical students often struggle to understand physiological concepts. Interactive learning through Peer instruction (PI) is known to stimulate students' comprehension, but its relative efficacy and working mechanisms remain to be elucidated. In this study, we investigated if and how PI could optimize comprehension of physiological concepts and transfer relative to Self-explanation (SE) which is considered a lower-order type of overt learning...
