In line, plasma Cxcl1 levels were elevated in ApoE-/-Svep1+/- mice. Our studies reveal an atheroprotective role of SVEP1. Deficiency of wild-type Svep1 increased endothelial CXCL1 expression leading to enhanced recruitment of proinflammatory leukocytes from blood to plaque. Consequently, elevated vascular inflammation resulted in enhanced plaque progression in Svep1 deficiency.

The diagnostic workup of ovarian tumors in children and adolescents is challenging because preserving fertility, in addition to oncological safety, is of particular importance in this population. Therefore, a thorough preoperative assessment of ovarian tumors is required.

To investigate the diagnostic value of MR imaging in differentiating benign from malignant ovarian tumors in children and adolescents.

We conducted a retrospective study of all children and adolescents age <18years who underwent MR imaging of ovarian tumors during 2014-2019 at a pediatric specialty center. Two radiologists reviewed all MR imaging. We used pathology reports to define the histological diagnosis.

We included 30 girls who underwent MR imaging for an ovarian tumor. Signs indicative for malignancy were tumors with a diameter ≥8cm, with areas of contrast enhancement, irregular margins, extracapsular tumor growth, and ascites. All benign and malignant ovarian tumors were correctly identified by the radiologists.

The diagnostic utility of MR imaging in classifying ovarian tumors in children and adolescents as benign or malignant is promising and might aid in defining the indication for ovarian-sparing versus non-ovarian-sparing surgery. We recommend evaluating these tumors with MR imaging prior to deciding on surgical treatment.

The Quebec Longitudinal Study of Child Development (QLSCD) was designed to examine the long-term associations of preschool physical, cognitive, social, and emotional development with biopsychosocial development across childhood, adolescence, and young adulthood.

QLSCD is an ongoing prospective cohort including 2120 singletons born in 1997/1998 in the Canadian province of Quebec. So far, data have been collected annually or every 2years from child ages 5months to 21years. The cohort currently includes 1245 participants. Data available include a range of environmental (e.g., family characteristics, child behaviour, educational attainment, mental health), biological (e.g., hair cortisol, genetic, epigenetic), and administrative data.

QLSCD has contributed to the understanding of children's psychosocial development, including the development of physical aggression and anxiety. QLSCD articles have advanced scientific knowledge on the influence of early childhood factors on childhood, adolescent, and young adnd administrative data, long-term follow-up with frequent data collections, and use of data from multiple informants, including teachers, mothers, fathers, and the children themselves.

The present study aimed to systematically review the literature about the interproximal anti-plaque and anti-gingivitis efficacy of cetylpyrydinium chloride (CPC) mouthrinse compared to placebo solution.

Three databases (PUBMED, SCOPUS, and EMBASE) were searched for randomized clinical trials that compared the interproximal anti-plaque and anti-gingivitis effect of CPC and placebo mouthrinses as an adjunct to toothbrushing, after a minimum of 6 weeks. Individuals with any periodontal diagnosis were considered. Two meta-analyses were performed for the Turesky modification of the Quigley-Hein plaque index and the Löe and Silness gingival index. For both analyses, the mean differences (MD) between baseline and 6-weeks were calculated using a random-effect model.

Eight studies were included. All included studies showed significant improvement in at least one of the parameters, favoring the CPC mouthrinse when compared to placebo. The meta-analysis demonstrated that groups that used CPC displayed a significantly greater reduction in the plaque index score (MD; 95% confidence interval [95%CI] - 0.70; - 0.83 to - 0.57) and in the gingival index (MD; 95%CI - 0.38; - 0.47 to - 0.28) when compared to placebo. However, high heterogeneity was observed in both analyses (I

= 89% and I

= 98%, respectively).

When considering interproximal surfaces, CPC is efficacious both in plaque and gingival inflammatory parameters, demonstrating the potential to compensate for the limitations of interproximal plaque control.

CPC may be a good alternative to compensate interproximal plaque removal, improving interproximal gingivitis.

The present retrospective study was designed to test the hypothesis that the postoperative posterior to preoperative anterior corneal curvature radii (PPPA) ratio in eyes with Fuch's dystrophy undergoing Descemet membrane endothelial keratoplasty (DMEK) is significantly different to the posterior to anterior corneal curvature radii (PA) ratio in virgin eyes and therefore renders conventional keratometry (K) and the corneal power derived by it invalid for intraocular lens (IOL) power calculation.

Measurement of corneal parameters was performed using Scheimpflug imaging (Pentacam HR, Oculus, Germany). In 125 eyes with Fuch's dystrophy undergoing DMEK, a fictitious keratometer index was calculated based on the PPPA ratio. The preoperative and postoperative keratometer indices and PA ratios were also determined. Results were compared to those obtained in a control group consisting of 125 eyes without corneal pathologies. Calculated mean ratios and keratometer indices were then used to convert the anterior corg conventional K for IOL power calculation is invalid in eyes with Fuch's dystrophy undergoing DMEK. To avoid an overestimation of corneal power and minimize the risk of a postoperative hyperopic shift, conventional K for IOL power calculation should be adjusted in eyes with Fuch's dystrophy undergoing cataract surgery combined with DMEK. The fictitious PPPA ratio and keratometer index may guide further IOL power calculation methods to achieve this.

LHON is characterized by bilateral subacute loss of vision due to the preferential loss of retinal ganglion cells (RGCs) within the inner retina, resulting in optic nerve degeneration. This review describes the clinical features associated with mtDNA LHON mutations and recent insights gained into the disease mechanisms contributing to RGC loss in this mitochondrial disorder. Although treatment options remain limited, LHON research has now entered an active translational phase with ongoing clinical trials, including gene therapy to correct the underlying pathogenic mtDNA mutation.

Cytomegalovirus (CMV) antigenemia assays have been widely used as adjunct tests to diagnose tissue invasive CMV diseases, including cytomegalovirus retinitis (CMVR). In this study, we examined CMVR cases to assess the presence of CMV in sera and aqueous humor and antiviral therapy received prior to the onset of CMVR.

A total of 37 eyes from 26 different cases of CMVR in patients who visited Hokkaido University Hospital between 2007 and 2015 were enrolled. The diagnosis of CMVR was established based on characteristic ophthalmoscopic findings and the presence of local and/or systemic CMV infection. buy Conteltinib Among the 26 cases, 3 cases (12%) were HIV-positive, while the other 23 cases (88%) were HIV-negative. The records of clinical and laboratory results were reviewed from clinical charts retrospectively.

CMV antigenemia was positive at the onset of CMVR in 14 cases (53.8%) and negative in the other 12 cases. In 9 cases among the antigenemia-negative cases (75.0%), the antigenemia had been previously positive and had turned negative before the onset of CMVR. In 12 of the 14 antigenemia-positive cases (85.7%) and in 8 of the 9 antigenemia-negative cases (88.9%) that were previously positive, systemic antiviral therapies had never been used or had been used before but had been discontinued prior to the onset of CMVR.

Even if viremia turns negative, the risk of developing CMVR exists for more than several weeks after the completion of systemic therapy.

To evaluate peripapillary retinal nerve fibre layer (RNFL) thickness measured by spectral domain optical coherence tomography (OCT) in patients with Stargardt disease (STGD).

A cross-sectional, monocentric, observational case-control study. Twenty patients (39 eyes) with ABCA4 mutations graded according to the Fishman STGD classification were included. RNFL measurement was performed using Heidelberg Spectralis SD-OCT. RNFL thickness in STGD patients was compared to age-matched data of healthy individuals provided by the device's manufacturer. A manual readjustment of the optic disc-fovea angle was performed when needed.

The mean age at first diagnosis of STGD was 22.9years (range 9 to 50) and 39.1years (range 18 to 74) at the time of examination. Thirty-nine percent of eyes (15 eyes) needed manual adjustment of the optic disc-fovea angle due to malfixation of the patients during OCT. The temporal quadrant corresponding to the macula showed a RNFL 16% thinner than controls (mean - 12μm, 95%CI - 9 to -15μm). However, global RNFL thickness did not differ from controls due to increased RNFL thickness of 12% in the nasal sectors. Duration and stage of STGD were not correlated to thinner RNFL.

STGD seems to be associated with thinner peripapillary RNFL in the sector of axons projecting to the degenerated macular area. It is yet unclear as to whether this results from anterograde transneuronal degeneration of direct injury to retinal ganglion cells.

To investigate the prognostic factors associated with functional and anatomical outcomes and to assess the longitudinal course of visual acuity and retinal morphology after vitreoretinal surgery for idiopathic epiretinal membrane (ERM).

This multicenter, retrospective study included a total of 634 eyes who underwent surgery for idiopathic ERM in 22 academic centers nationwide in Turkey. Data on best-corrected visual acuity (BCVA) and optical coherence tomography features (central foveal thickness (CFT), ERM and foveal contour morphology, ellipsoid zone (EZ) integrity) were collected and compared at baseline, 6-month, 12-month, and 24-month follow-ups. Prognostic factors for functional (having ≥ 20/25 Snellen BCVA) and anatomical (having normal/shallow foveal contour) recoveries after surgery were investigated by means of multivariate regression analyses. A cutoff value of preoperative BCVA optimizing functional recovery was calculated using receiver operating characteristic curve analysis.

At a median follow-up of 24months, 37.
