Bodily Fluids As The Basis For Digital Health

Blood, saliva, urine, sweat or even ear wax can carry valuable information about an individual’s medical state. Until now, even simpler tests on such bodily fluids had to be carried out at medical facilities, but with the recent uptick in the development of digital diagnostic technologies, more and more solutions appear on the market which enable the patient to do such tests at home. Here we take a look around the bodily fluid business. From bloodletting to digital sweat measurement Blood, yellow bile, black bile, phlegm. Although it doesn’t sound appealing, the ancient Greek already thought that bodily fluids make up the fundamentals of the human body and that diseases only appear when the organism, or rather these liquids lose their balance. The humoral theory was central to the teachings of Hippocrates, and it became the dominant theory of medical thinking and practice in Europe until the late 1800s. For example, in the rather barbaric practice of bloodletting. Medical professionals believed that letting out “bad blood” would stimulate the body to produce fresh and healthy blood and stop hemorrhages. Modern medicine still bases healing on bodily fluids: blood, mucus, feces, saliva, semen, sweat, tears, urine, and even ear wax contain valuable information about a person’s health. Physicians use a swarm of tests during diagnosis (e.g., urine tests), therapy (e.g., stool sample culture tests), or monitoring (e.g., blood tests during chem...

Popovici V Abstract The dysfunction of the DNA mismatch repair system results in microsatellite instability (MSI). MSI plays a central role in the development of multiple human cancers. In colon cancer, despite being associated with resistance to 5-fluorouracil treatment, MSI is a favourable prognostic marker. In gastric and endometrial cancers, its prognostic value is not so well established. Nevertheless, recognising the MSI tumours may be important for predicting the therapeutic effect of immune checkpoint inhibitors. Several gene expression signatures were trained on microarray data sets to understand the reg...

Abstract Objectives: To investigate the influence of statins on major adverse cardiovascular events (MACE) in patients with coronary microvascular dysfunction (CMVD). Participants: 23,494 patients who received coronary angiography (CAG) were included. Thrombolysis in Myocardial Infarction, Myocardial Perfusion Grading (TMPG), a useful angiographic method, was used to evaluate CMVD. Results: Using multivariate analysis, NYHA III/IV (HR, 1.44; 95% CI, 1.03-2.01; P=0.031), PCI history (HR, 3.69; 95% CI, 2.57-5.31; P

Authors: Ravindranath MH, Filippone EJ, Devarajan A, Asgharzadeh S Abstract Cytotoxic NK/CD8+ T cells interact with MHC-I ligands on tumor cells through either activating or inhibiting receptors. One of the inhibitory receptors is CD94/NKG2A. The NK/CD8+ T cell cytotoxic capability is lost when tumor-associated human leukocyte antigen, HLA-E, binds the CD94/NKG2A receptor, resulting in tumor progression and reduced survival. Failure of cancer patients to respond to natural killer (NK) cell therapies could be due to HLA-E overexpression in tumor tissues. Preventing the inhibitory receptor-ligand interaction by eithe...

Authors: Pencheva-Demireva M, El-Darawish Y, Kavaldzhieva K, Mladenov N, Lazarov V, Dimitrova-Dikanarova D, Markova T, Nikolov R, Okamura H Abstract Natural killer (NK) cells can discriminate between normal and cancer cells and are known to directly recognize and kill malignant cells or induce apoptosis. Thus, activation of NK cells is considered as a promising strategy for cancer treatment. However, clinical application has been somewhat limited because of difficulties in the preparation of sufficient number of highly cytotoxic/activated NK cells in vitro. We used cytokine stimulation to provide a suitable environ...

Abstract PROBLEM IDENTIFICATION: The impact of mental health disorders (MHDs) and substance use disorders (SUDs) on healthcare utilization (HCU) in patients with cancer is an understudied phenomenon. LITERATURE SEARCH: A literature search of studies published prior to January 2018 that examined HCU in patients with preexisting MHDs or SUDs diagnosed with cancer was conducted. DATA EVALUATION: The research team evaluated 22 studies for scientific rigor and examined significant trends in HCU, as well as types of the MHD, SUD, and cancer studied. SYNTHESIS: The heterogeneity of HCU outcome measures, MH...

This study provides insight into the experiences of young women living with advanced breast cancer. Because these women may not appear ill to the general population, their needs and struggles are not well understood. The results of this study can be a baseline for additional research and clinical interventions. PMID: 31007263 [PubMed - in process]
