The approach to the treatment of nausea and vomiting in a cancer patient should begin with a complete assessment, including the frequency, duration, and intensity of the nausea/vomiting; associated activities; and whether anorexia or cachexia is present. It is important to determine whether the nausea and vomiting is related to treatment (chemotherapy, radiation) or is independent of cancer treatment. Nausea/vomiting unrelated to chemotherapy and/or radiation may have an etiology for which there is a specific and potentially successful intervention...

The majority of World Health Organization grade II and grade III gliomas harbor heterozygous mutations in the metabolic enzyme isocitrate dehydrogenase 1 (IDH1), and tumors with an IDH wild-type status show molecular features of a glioblastoma and simply may constitute a separate disease entity. This discovery has led to a profound shift in the way that gliomas are classified and, consequently, how treatment decisions are made. We will review the current understanding of IDH- mutant gliomagenesis and the preclinical models being used to investigate the underlying biology of these tumors and to explore new therapeutic options for these patients...

The presence of hypertension in individuals with type 2 diabetes augments the risk for cardiovascular morbidity and mortality. In this regard, data support that management of hypertension in this high-risk population is a critical risk reduction strategy. In recent years, a number of work groups have redefined hypertension, management strategies, and targets. In this context, there is still considerable discussion on an appropriate target for blood pressure in the diabetic population. However, despite this discussion on target blood pressure, it is widely recognized that there is considerable residual risk for heightened cardiovascular events in the hypertensive, diabetic population despite widespread awareness and treatment...

Psychotic disorders often have been linked with violence. However, studies have shown that people with a psychotic disorder are more often victim than perpetrator of violence. The objective of this meta-analysis was to review prevalence rates for different types of victimization and to identify risk factors associated with victimization. Based on a search in MEDLINE, PsycINFO, and Web of Science, 27 studies were found with samples consisting of adults with a psychotic disorder and possible victimization occurring during adulthood and data on "violent victimization," "sexual victimization," "non-violent victimization," and/or "victimization not otherwise specified...

OBJECTIVE: Marfan syndrome (MFS) is a systemic connective tissue disorder caused by insufficient fibrillin-1 (FBN-1), a major component of microfibrils that controls the elasticity and integrity of connective tissues. FBN-1 insufficiency in MFS leads to structural weakness, which causes various tissue disorders, including cardiovascular and periodontal disease. However, the role of FBN-1 insufficiency in the destruction and regeneration of connective tissue has not yet been clarified...

Increasing access to early care and education (ECE) for children in the child welfare system (CWS) remains a critical issue in the United States, as the numbers of young children entering this system steadily increases. Mounting evidence suggests that participation in at least some types of ECE can mitigate the need for child welfare supervision. Moreover, ECE participation has been linked to positive developmental and school readiness outcomes, lower rates of foster placement, and greater placement stability for children in the CWS...

The final goal in the management of patients with type 2 diabetes (T2D) is reduction in cardiovascular (CV) complications and total mortality. Various factors including hyperglycemia contribute to these complications and mortality directly and indirectly. In recent years, large-scale CV outcome trials with new antidiabetic medications, such as dipeptidyl peptidase-4 (DPP4) inhibitors, glucagon-like peptide-1 (GLP1) receptor agonists, and sodium glucose cotransporter-2 (SGLT2) inhibitors, have been completed...

Vascular smooth muscle cells (VSMCs) transdifferentiate into osteoblast-like cells during vascular calcification, inducing active remodeling and calcification of the extracellular matrix (ECM). Intracellular and extracellular enzymes, such as lysyl hydroxylase 1 (PLOD1) and lysyl oxidase (LOX), contribute to ECM maturation and stabilization. We assessed the contribution of these enzymes to hyperphosphatemia (HPM)-induced calcification. Human and murine VSMCs were differentiated into functional osteoblast-like cells by HPM conditioning...

Any type of breast cancer not expressing genes of the estrogen receptor (ER), progesterone receptor (PR), or human epidermal growth factor receptor 2 (HER2) is referred to as triple-negative breast cancer (TNBC). Accordingly, TNBCs do not respond to hormonal therapies or medicines targeting the ER, PR, or HER2. Systemic chemotherapy is therefore the only treatment option available today and prognoses remain poor. We report the discovery and characterization of N-(naphtho[1,2-b]furan-5-yl)benzenesulfonamides as selective inhibitors of TNBCs...

During hemodialysis (HD), blood is circulated through an extracorporeal tubing system (bloodline) made of medical-grade polymeric material. Sensors of various types that do not come into contact with blood (optical, electromagnetic, etc.) are applied directly across the bloodline for clinical purposes and for therapy customization. Thus, a detailed knowledge of the bloodline's physical properties is useful for the development of next-generation HD sensors. In this work, we performed a novel comparative analysis of the materials used by the manufacturers of the bloodlines...

The artificial pancreas (AP) system is designed to regulate blood glucose in subjects with type 1 diabetes using a continuous glucose monitor informed controller that adjusts insulin infusion via an insulin pump. However, current AP developments are mainly hybrid closed-loop systems that include feed-forward actions triggered by the announcement of meals or exercise. The first step to fully closing the loop in the AP requires removing meal announcement, which is currently the most effective way to alleviate postprandial hyperglycemia due to the delay in insulin action...

The fundamental function of ribonucleic acids is to transfer genetic information from DNA to protein during translation process, however, this is not the only way connecting active RNA sequences with essential biological processes. Up until now, many RNA subclasses of different size, structure, and biological function were identified. Among them, there are non-coding single-stranded microRNAs (miRNAs). This subclass comprises RNAs of 19-25 nucleotides in length that modulate the activity of well-defined coding RNAs and play a crucial role in many physiological and pathological processes...

Selenoprotein P (SeP), a liver-derived secretory protein, functions as a selenium supply protein in the body. SeP has been reported to be associated with insulin resistance in humans through serial analysis of gene expression. Recently, SeP has been found to inhibit vascular endothelial growth factor-stimulated cell proliferation in human umbilical vein endothelial cells, and impair angiogenesis in a mouse hind limb model. In this study, the role of SeP in ischemia/reperfusion (I/R) injury has been investigated...
