© 2020 Hermanova et al.To study the role of myeloid cells in the central nervous system (CNS) in the pathogenesis of multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), we used intravital microscopy, assessing local cellular interactions in vivo in EAE animals and ex vivo in organotypic hippocampal slice cultures. We discovered that myeloid cells actively engulf invading living Th17 lymphocytes, a process mediated by expression of activation-dependent lectin and its T cell-binding partner, N-acetyl-D-glucosamine (GlcNAc). Stable engulfment resulted in the death of the engulfed cells, and, remarkably, enhancement of GlcNAc exposure on T cells in the CNS ameliorated clinical EAE symptoms. These findings demonstrate the ability of myeloid cells to directly react to pathogenic T cell infiltration by engulfing living T cells. Amelioration of EAE via GlcNAc treatment suggests a novel first-defense pathway of myeloid cells as an initial response to CNS invasion and demonstrates that T cell engulfment by myeloid cells can be therapeutically exploited in vivo. © 2020 Wasser et al.OBJECTIVE Our aim was to give an overview of the effectiveness of adjunctive analgesics in head and neck cancer (HNC) patients receiving (chemo-) radiotherapy. DESIGN Systematic review. INTERVENTIONS This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Embase, Web of Science, the Cochrane Library, and ClinicalTrials.gov were searched for studies concerning "head neck cancer," "adjunctive analgesics," "pain," and "radiotherapy." OUTCOME MEASURES Pain outcome, adverse events, and toxicity and other reported outcomes, for example, mucositis, quality of life, depression, etc. RESULTS Nine studies were included in our synthesis. Most studies were of low quality and had a high risk of bias on several domains of the Cochrane Collaboration tool. Only two studies comprised high-quality randomized controlled trials in which pregabalin and a doxepin rinse showed their effectiveness for the treatment of neuropathic pain and pain from oral mucositis, respectively, in HNC patients receiving (chemo-) radiotherapy. CONCLUSIONS More high-quality trials are necessary to provide clear evidence on the effectiveness of adjunctive analgesics in the treatment of HNC (chemo-) radiation-induced pain. © The Author(s) 2020.

Despite regulatory efforts to phase out legacy PFAS, they remain detectable in drinking water throughout the United States. This is due to the stability of legacy PFAS and the continued use of replacement compounds. In humans, PFAS have been detected in placenta and cord blood and are associated with low birthweight and preeclampsia risk. Tween 80 chemical structure Preeclampsia is a leading cause of maternal mortality and is driven by insufficient endometrial trophoblast invasion, resulting in poor placental blood flow. PFAS alter invasion of other cell types, but their impact on trophoblasts is not understood. We therefore assessed the effects of PFAS on trophoblast migration, invasion, and gene expression in vitro. Trophoblast migration and invasion was assessed using a modified scratch assay in the absence or presence of Matrigel, respectively. Treatment with perfluorooctanoic sulfate (PFOS), perfluorooctanoic acid (PFOA), and GenX (1000 ng/mL) each decreased trophoblast migration over 24 h. However, only GenX (1000 ng/mL) significantly inhibited trophoblast invasion. Treatment with PFOS, PFOA, and GenX also decreased trophoblast expression of chemokines (e.g. CCL2), chemokine receptors (e.g. CCR4), and inflammatory enzymes (e.g. ALOX15) involved in migration. Inhibition of chemokine receptors with pertussis toxin (10 ng/mL), a G-protein inhibitor, inhibited trophoblast migration similar to the PFAS. Taken together, PFAS decrease trophoblast migration, invasion, and inflammatory signaling. By understanding the mechanisms involved, it may be possible to identify the biological and exposure factors that contribute to preeclampsia. © The Author(s) 2020.

We sought to describe opioid consumption patterns after an ED visit for acute pain. DESIGN Descriptive study with data derived from a larger interventional study promoting safe opioid use after ED discharge. SETTING Urban academic emergency department (>88,000 annual visits). SUBJECTS Patients were eligible if age >17 years, not chronically using opioids, and newly prescribed hydrocodone-acetaminophen and were included in the analysis if they returned the completed 10-day medication diary. METHODS Patient demographics and opioid consumption are reported. Opioid use is described in daily number of pills and daily morphine milligram equivalents (MME) both for the sample overall and by diagnosis. RESULTS Two hundred sixty patients returned completed medication diaries (45 [17%] back pain, 52 [20%] renal colic, 54 [21%] fracture/dislocation, 40 [15%] musculoskeletal injury [nonfracture], and 69 [27%] "other"). The mean age (SD) was 45 (15) years, and 59% of the sample was female. A median of 12 pills were prescribed. Patients with renal colic used the least opioids (total pills median [interquartile range IQR] = 3 [1-7]; total MME median [IQR] = 20 [10-50]); patients with back pain used the most (total pills median [IQR] = 12 [7-16]; total MME median [IQR] = 65 [47.5-100]); 92.5% of patients had leftover pills. CONCLUSIONS In this sample, pill consumption varied by illness category; however, overall, patients were consuming low quantities of pills, and the majority had unused pills 10 days after their ED visit. © The Author(s) 2020.
