Gemcitabine (GEM) is currently a standard chemotherapeutic agent for metastatic urothelial carcinoma (mUC). Fever isknown to be an adverse effect of GEM ; however, itsincidence, etiology and clinical significance have not been evaluated. The objective of this study was to elucidate the characteristics and clinical significance of fever associated with GEM in patients with mUC receiving GEM plus cisplatin (GC) chemotherapy. Between 2005 and 2014, 184 patientswith mUC who received first-line GC therapy at 10 institutions were enrolled. GEM-associated fever (GEMAF) was defined as a body temperature ≥37.5ºC within 96 hours after administration of GEM with no evidence of specific conditions causing fever including infection. Clinical parametersbefore GC therapy were evaluated to determine predictorsof GEMAF. Furthermore, the impact of GEMAF on clinical outcomeswasals o evaluated. The median age was70 years and median follow-up was14.2 months. GEMAF wasobs erved in 44 patients (23.9%). In multivariate analysis, elevated C-reactive protein (CRP) before chemotherapy was an independent predictive factor for GEMAF (oddsratio 2.450, p＝0.041). There was a significant difference in progression-free survival (median 6.7 vs 8.0 months, p＝0.031) and cancer-specific survival (median 12.0 vs 15.8 months, p＝0.045) between patients with and without GEMAF. Results of this study suggest that GEMAF is a common adverse event of GC therapy for mUC and can be a poor prognostic factor.  https://www.selleckchem.com/products/e-7386.html  GEMAF may be associated with systemic inflammatory response induced by the tumor in patients with mUC.
  The long-term and high-dose use of doxorubicin as chemotherapy for triple-negative breast cancer (TNBC) patients induces epithelial-to-mesenchymal transition (EMT) and stimulates cancer metastasis. Cinnamaldehyde is a major compound of cinnamon oil (CO) suppressing Snail and NFκB activity that are involved in cell migration. This study aims to explore the activity of CO as a co-chemotherapeutic agent on 4T1 breast cancer cells.
 
  The CO was obtained by water and steam distillation and was characterized phytochemically by gas chromatography-mass spectrometry (GC-MS). Cytotoxic activity of single CO or in combination with doxorubicin was observed by MTT assay. Cell migration and MMP-9 expression were measured by scratch wound healing and gelatin zymography assays. The intracellular reactive oxygen species (ROS) levels were observed by 2',7'-dichlorofluorescin diacetate (DCFDA) staining flowcytometry.
 
  The phytochemical analysis with GC-MS showed that CO contains 14 compounds with cinnamaldehyde as the major compound. CO exhibited cytotoxicity on 4T1 cells with the IC
  value of 25μg/mL and its combination with doxorubicin decreased cell viability and inhibited cell migration compared to a single use. Furthermore, the combination of CO and doxorubicin inhibited MMP-9 expression and elevated intracellular ROS levels compared to control.
 
  CO has the potential to be developed as a co-chemotherapy agent through inhibition of cell migration, and intracellular ROS levels elevation.

  Hashimoto's thyroiditis (HT) is the most common cause of goiter and acquired hypothyroidism in children and adolescents, especially in areas without endemic iodine deficiency. We aimed to evaluate the follow-up results of children and adolescents diagnosed with HT, including clinical, biochemical, and radiological findings and treatment approaches.
 
  HT patients, who were diagnosed between 2012 and 2018 years in a single-center, were assessed retrospectively.
 
  Two hundred and twenty-four cases were included in the study, 75.9% of whom were girls (female/male ratio 3.1) and 66.5% were pubertal. The median age of the cases at first admission was 12.5 (9.2-15) years. The median follow-up period of 196 patients, who continued their follow-up regularly, was 2.1 (0.7-4.8) years. When autoantibody levels were analyzed according to gender, mean anti-Tg levels were higher in girls (p=0.028), whereas anti-TPO levels were similar (p=0.372). A nodule was detected in the ultrasonographic follow-up of 29 (13%) patients. Papillary thyroid carcinoma was observed in 10.3% (n=3) of those with nodules. When the last ultrasonography findings of 188 patients with available radiological follow-up data were compared with their initial evaluation, the rate ofheterogeneous parenchymal echogenicity increased significantly (p=0.008). The need for l-thyroxine dosage augmented over time.
 
  Although HT is more common in adolescent girls, it can be encountered in both genders and at all ages in childhood. The incidence of malignancy was not higher in patients with nodules associated with HT than the reported incidences of malignancy in nodules not associated with HT.

  To assess the diagnostic accuracy and agreement between a paediatric electroretinography protocol used at Great Ormond Street Hospital (GOSH-ERG) and the 'gold standard' international protocol (ISCEV-ERG) in health and disease.
 
  Patient databases between 2010 and 2020 were screened to identify children with an ISCEV-ERG recorded within four years of a GOSH-ERG. Electroretinogram (ERG) component peak times and amplitudes were re-measured, and data were analysed in terms of absolute abnormality and proportional deviation from respective reference ranges. Abnormality was defined by the retinal system affected and by individual ERG a- and b-wave component analysis.
 
  A total of 59 patients were included 38 patients had retinal disease defined by an abnormal ISCEV-ERG and 21 had normal ISCEV-ERGs. When absolute abnormality was defined by combined retinal systems, the GOSH-ERG showed an excellent overall sensitivity of 95% (accuracy 86%). Individual retinal systems showed good-excellent sensitivity (67%-100%) and specificity (68%-97%).
