BACKGROUND/PURPOSE Colorectal cancer (CRC) is one of the most common malignant tumours and is associated with a high mortality rate due to the lack of specific biomarkers available for early diagnosis, targeted therapies and prognostic surveillance. In the present study, we investigated the function of Numb and its underlying mechanism in colorectal cancer. METHODS Immunohistochemical staining and clinicopathological analysis were used to assess the expression of Numb and its clinical significance in patients with colorectal cancer. Quantitative real-time polymerase chain reaction, cell proliferation, western blot, wound healing, Transwell and TOP/FOP flash reporter assays were used to investigate the function of Numb and its underlying mechanism in colorectal cancer. RESULTS Numb expression was down-regulated and negatively correlated with the depth of invasion, tumour size, metastasis, TNM stage and EMT markers in colorectal cancer specimens. Numb negatively regulates the EMT, proliferation, invasion, migration and the Wnt signalling pathway in vitro, as well as tumour growth and metastasis in vivo. Furthermore, activation of the Wnt signalling pathway by Wnt-3A negated the effect of Numb overexpression, while inhibition of the Wnt signalling pathway by IWR-1 impaired the effect of the Numb knockdown on the EMT. CONCLUSION Numb downregulation is a common event in patients with colorectal cancer and is closely correlated with cancer progression and a poor prognosis. Numb functions as a tumour suppressor in colorectal cancer, and its tumour suppressor function is mediated by negative regulation of the EMT through the Wnt signalling pathway.The gastrointestinal tract houses a reservoir of bacterial-derived enzymes which can directly catalyze the metabolism of drugs, dietary elements, and endogenous molecules. Both host and environmental factors may influence this enzymatic activity, with the potential to dictate the availability of the biologically-active form of endogenous molecules in the gut and influence inter-individual variation in drug metabolism. We aimed to investigate the influence of the microbiota, and the modulation of its composition, on fecal enzymatic activity. Intrinsic factors related to the host, including age, sex, and genetic background, were explored. Fecalase, a cell-free extract of feces, was prepared and used in a colorimetric-based assay to quantify enzymatic activity. To demonstrate the functional effects of fecal enzymatic activity, we examined β-glucuronidase-mediated cleavage of serotonin β-D-glucuronide (5-HT-GLU) and the resultant production of free 5-HT by HPLC. As expected, β-glucuronidase and β-glucosidase activity were absent in germ-free mice. Enzymatic activity was significantly influenced by mouse strain and animal species. Sex and age significantly altered metabolic activity with implications for free 5-HT. β-glucuronidase and β-glucosidase activity remained at reduced levels for nearly two weeks after cessation of antibiotic administration. This effect on fecalase corresponded to significantly lower 5-HT levels as compared to incubation with pre-antibiotic fecalase from the same mice. Dietary targeting of the microbiota using prebiotics did not alter β-glucuronidase or β-glucosidase activity. Our data demonstrate that multiple factors influence the activity of bacterial-derived enzymes which may have potential clinical implications for drug metabolism and the deconjugation of host-produced glucuronides in the gut.Objective To examine the evidence for emerging treatment options, buprenorphine or clonidine, as monotherapy for the treatment of neonatal abstinence syndrome (NAS) against standards of care, morphine or methadone.Data sources A PubMed literature search from 1946 to 2019 was performed using the terms NAS, neonatal withdrawal, buprenorphine and NAS, clonidine and NAS, morphine and NAS, methadone and NAS, opioids and pregnancy, opioids and NAS, prenatal exposure and opioids.Study selection and data extraction Study evaluation was limited to English-language studies conducted in humans. Articles were eliminated if subjects did not have a formal diagnosis of NAS. Additionally, studies were eliminated if neonates received diluted tincture of opium. Additional references were identified from a manual citation review.Relevance to patient care and clinical practice Eight articles were evaluated. Five articles compared buprenorphine to either morphine or methadone. Buprenorphine was found to decrease length of NAS treatment an average of 9.2 days and decrease hospital length of stay (LOS) an average of 8.2 days. Three articles evaluated the use of clonidine for NAS, two as an adjunct to morphine and one as monotherapy. Adjunctive clonidine plus morphine versus phenobarbital plus morphine both significantly reduced the total morphine treatment duration; however, patients remained on adjunctive phenobarbital significantly longer than clonidine. EGF816 As monotherapy, clonidine was found to decrease NAS treatment an average of 11 days and decrease overall LOS an average of six days compared to morphine treatment.Conclusion Treatment with buprenorphine or clonidine has shown favorable effects by reducing length of NAS treatment and LOS. These emerging therapies may be as effective as morphine or methadone for NAS, in combination with nonpharmacologic strategies. Long-term follow-up is needed.Objective Neonatal brain injury is a potentially devastating cause of neurodevelopmental impairment. There is no consensus, however, on the appropriate timing and frequency of routine head ultrasound (HUS) screening for such injuries. We evaluated the diagnostic utility of routine HUS screening at 30 days of life ("late HUS") for detecting severe intraventricular hemorrhage (IVH) or cystic periventricular leukomalacia (c-PVL) in preterm infants with a negative HUS before 14 days of life ("early HUS").Methods Single-center retrospective cohort analysis of infants born at ≤ 32 weeks gestational age (GA) admitted to the University of Nebraska Medical Center NICU from 2011-2018. Demographics, HUS and MRI diagnoses were abstracted from clinical records. Fisher's exact test and t-test assessed associations between categorical and continuous variable, respectively.Results 205 infants were included-120 very preterm (28-32 weeks GA) and 85 extremely preterm ( less then 28 weeks GA). Negative predictive value of early HUS for predicting any clinically significant anomalies (severe IVH or c-PVL) on late HUS was 100% for extremely and 99.
