Dynamic Structural Equation Modeling was used to investigate the daily levels and short-term daily dynamics of conflict, revealing that for most families there were no day-to-day lagged associations between marital conflict and mother-adolescent conflict. Results showed that long-term conflict resolution patterns did not moderate the short-term dynamics of daily conflict. However, differences among long-term marital conflict resolution patterns were found in the levels of daily conflict, such that in families with long-term destructive conflict resolution patterns, daily conflict intensity was higher.

Dermatophytosis is a world-wide distributed common infection. Antifungal drug resistance in dermatophytosis used to be rare, but unfortunately the current Indian epidemic of atypical widespread recalcitrant and terbinafine-resistant dermatophytosis is spreading and has sporadically been reported in Europe.
To explore the occurrence of clinical and mycological proven antifungal drug resistance in dermatophytes in Europe.
A standardized questionnaire was distributed through the EADV Task Force of Mycology network to dermatologists in Europe.
Representatives from 20 countries completed the questionnaires of which 17 (85 %) had observed clinical and/or mycological confirmed antifungal resistance, two countries published cases of antifungal resistance and one country had no known cases.
This pilot study confirms that both clinical and mycological antifungal resistance exist in Europe.

Antineoplastic activity of atractylenolide III (ATL) has been reported in several malignant tumors. However, its activity has not been completely clarified in hepatocellular carcinoma (HCC). Herein, anticancer effects and underlying molecular mechanisms of ATL were investigated in HCC cells in vitro.
Cell viability was evaluated by CCK-8 assay. Cell migration and invasion were evaluated using the transwell assay. TUNEL staining was performed to evaluate cell apoptosis. Protein expression was measured by western blotting analysis. Online database TargetScan and luciferase reporter gene analysis were performed to validate FGFR1 as a target of miR-195-5p.
HepG2 and SMMC7721 cell growth, migration, and invasion were inhibited by ATL treatment in a dose-dependent pattern. ATL treatment-induced apoptosis of HepG2 and SMMC7721 cells. Intriguingly, ATL treatment unexpectedly inhibited FGFR1 protein expression in HepG2 and SMMC7721 cells. Knockdown of FGFR1 inhibited proliferation, migration, and invasion, and evoked apoptosis of HepG2 and SMMC7721 cells. We also found that ATL treatment could increase the expression of miR-195-5p, which as a posttranscriptional targeted FGFR1. In HCC tissues, miR-195-5p expression is negatively correlated with FGFR1. Furthermore, the antiproliferative and proapoptotic roles of miR-195-5p were neutralized by overexpressed FGFR1 in HCC cells.
ATL effectively repressed growth and induced apoptosis of human HCC cells through the upregulation of miR-195-5p to downregulate FGFR1 expression.

Carnosine is a well-known endogenous antioxidant, which counteracts aging-induced Aβ plaque formation. The aim of this study was to investigate the effects of exogenous carnosine treatments on aging-induced changes (a) in the steady-state level of endogenous carnosine and conformation of Aβ secondary structure in the different brain regions (cerebral cortex, hippocampus, hypothalamus, pons-medulla, and cerebellum) and (b) cognitive function. Young (4 months) and aged (18 and 24 months) male albino Wistar rats were treated with carnosine (2.0 μg kg-1 day-1 ; i.t.) or equivalent volumes of vehicle (saline) for 21 consecutive days and were tested for cognition using 8-arm radial maze test. Brains were processed to assess the conformational integrity of Aβ plaques using Raman spectroscopy and endogenous levels of carnosine were measured in the brain regions using HPLC. Results indicated that carnosine treatments improved the aging-induced deficits in cognitive function and reduced the β-sheets in the secondary structure of Aβ protein, as well as mitigating the reduction in the steady-state levels of carnosine and spine density in the brain regions examined. These results thus, suggest that carnosine can attenuate the aging-induced (a) conformational changes in Aβ secondary structure by reducing the abundance of β-sheets and reductions in carnosine content in the brain regions and (b) cognitive impairment.Earlier diagnosis and treatment of intrahepatic cholangiocarcinoma (iCCA) are necessary to improve therapy, yet limited information is available about initiation and evolution of iCCA precursor lesions. Therefore, there is a need to identify mechanisms driving formation of precancerous lesions and their progression towards invasive tumors using experimental models that faithfully recapitulate human tumorigenesis. To this end, we generated a new mouse model which combines cholangiocyte-specific expression of KrasG12D with 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet-induced inflammation to mimic iCCA development in patients with cholangitis. Histological and transcriptomic analyses of the mouse precursor lesions and iCCA were performed and compared with human analyses. The function of genes overexpressed during tumorigenesis was investigated in human cell lines. We found that mice expressing KrasG12D in cholangiocytes and fed a DDC diet developed cholangitis, ductular proliferations, intraductal papillary neoplasms of bile ducts (IPNBs) and eventually iCCAs. The histology of mouse and human IPNBs were similar, and mouse iCCAs displayed histological characteristics of human mucin-producing large duct type iCCA. Signaling pathways activated in human iCCA were also activated in mice. The identification of transition zones between IPNB and iCCA on tissue sections, combined with RNA-sequencing analyses of the lesions supported that iCCAs derive from IPNBs. We further provide evidence that Tensin-4 (TNS4), which is stimulated by KRASG12D and SRY-related HMG box transcription factor 17 (SOX17), promotes tumor progression. CONCLUSION We developed a novel mouse model that faithfully recapitulates human iCCA tumorigenesis and identified a gene cascade which involves TNS4 and promotes tumor progression.
We sought to determine if radiographic pneumoconiosis predicts abnormal gas exchange during exercise in coal mine workers with preserved resting lung function.
We analyzed data from former coal miners seen between 2006 and 2014 in a single clinic specializing in black lung evaluations. We limited the analysis to those with normal resting spirometry and an A-a gradient at peak exercise ≥10 mmHg. We used multivariable logistic regression to estimate predictors of A-a gradient widened to >150% of the reference value. We focused on chest radiographs consistent with pneumoconiosis, taking into account higher silica exposure mining activities and years underground, and adjusting for cigarette smoking, obesity, and coronary artery disease.
Of 5507 miners, we analyzed data for 742 subjects with normal spirometry and all key clinical variables available, of whom 372 (50.1%) had radiographic evidence of pneumoconiosis. All but 21 had small opacity profusion of less than 2/1. 1-Thioglycerol The median A-a gradient at peak exercise was 108% of reference value (interquartile range, 81%-141%). In the multivariable analysis, radiographic pneumoconiosis was associated with increased odds of widened A-a gradient (odds ratio [OR], 2.47; 95% confidence interval [CI], 1.7-3.7). Limited to 660 subjects with normal diffusing capacity for carbon monoxide, the odds were similarly increased (OR, 3.20; 95% CI, 1.5-3.6).
Among coal miners with preserved resting lung function, radiographic evidence of early pneumoconiosis more than doubled the odds of abnormal exercise physiology. Impairment in pneumoconiosis occurs in early disease and may only be evident on exercise testing.

It has been associated with a spectrum of pigmentary cutaneous side effects. Despite the well-known association of eruptive melanocytic nevi with the use of other tyrosine kinase inhibitors, this phenomenon has not been linked to the administration of imatinib. We present the first case of imatinib-induced eruptive nevi in an 18-year-old patient with acute lymphocytic leukaemia in remission.
Recently, several scores to quantify compliance with the guidelines in candidaemia management (EQUAL, GEMICOMED, Valerio) have been developed. Evidence supporting the association of these scores to the prognosis is scarce. We aim to evaluate the performance of these candidaemia guideline adherence scores to predict candidaemia outcome.
We recorded retrospectively data from candidaemia episodes (January 2017-December 2018). We analysed adherence to guidelines for candidaemia management according to EQUAL, GEMICOMED and Valerio scores, and we correlated those to outcome.
Fifty-four first episodes of candidaemia were retrieved. Five patients who died in the first 48hours after blood cultures were not included. Thirty-day mortality in evaluable patients was 18.4%. Median adherence to guidelines according to EQUAL score was 17 (interquartile range [IQR] 15-19), and according to GEMICOMED was 86% (IQR 72.5%-100%). According to Valerio score, adequacy of antifungal prescription was 8.5/10 (SD 1.9). A cut-off of ≥17 for EQUAL or compliance >70% for GEMICOMED was associated with inferior 30-day mortality (7.1% vs 33.3%, P=.028 and 7.9% vs 54.5%, P=.002, respectively). Infectious diseases (ID) evaluated cases obtained a better EQUAL score (>17; 82.1% vs 42.9%, P=.006), had inferior 30-day mortality (9.4% vs 35.3%, P=.049) and a better antifungal prescription adequacy (Valerio score 9.0 vs 7.5, P=.011).
Adherence to guidelines for candidaemia management evaluated by means of EQUAL and GEMICOMED score was associated with a decreased 30-day mortality. Adequacy of antifungal prescription can be ameliorated. ID consultation improved guideline adherence and was associated with decreased 30-day mortality.
