Alopecia areata (AA) is an autoimmune T CD8 cell mediated condition clinically characterized by hair loss from single or few small patches to complete hair loss. The management of AA is challenging and all available therapies does not ensure a long-term remission. To assess the safety and efficacy of both systemic and topical brevilin A, a natural compound, in AA patients not responding to other treatments. After obtaining informed consent, we administered off-label brevilin A to 13 adult patients affected by AA, for a period ranging from 6 to 18 months. Medical records for each patient and the severity of alopecia tool (SALT) score before and after brevilin A administration were recorded. The mean SALT score of our patients was 81.03 (SD 34.9) at baseline and 75.8 (SD 37.4) after brevilin A therapy, meaning no statistically significant improvement was observed (P = .2385 Paired t test). However, three multifocal AA (MAA) patients out of four attained an improvement (75%) suggesting that brevilin A may be represent an alternative therapy in this form of AA. Authors conclude that brevilin A could represent in the future a possible effective treatment in MAA forms but further studies are required.
To explore whether neurosonography can detect differences in cortical development and corpus callosal length in late-onset small fetuses subclassified into small-for-gestational age (SGA) or growth restricted (FGR).
This was a prospective cohort study in singleton pregnancies, including normally grown fetuses (birth weight between the 10
and 90
centiles) and late-onset small fetuses (estimated fetal weight < 10
centile, diagnosed after 32 weeks of gestation and confirmed by birth weight < 10
centile). Small fetuses were subclassified into SGA (birth weight between the 3
and 9
centiles and normal fetoplacental Doppler) and FGR (birth weight < 3
centile and/or abnormal cerebroplacental ratio and/or abnormal uterine artery Doppler). Neurosonography was performed at 33 ± 1 weeks of gestation to assess the depth of the insula, Sylvian fissure and parieto-occipital sulcus in the axial views and corpus callosal length in the midsagittal plane. Measurements were performed offline using Almatween the FGR and control groups. Corpus callosal length adjusted for cephalic index was significantly reduced in FGR cases compared with both controls and SGA cases, while there was no difference between SGA cases and controls (median (interquartile range), controls 0.500 (0.478-0.531) vs SGA 0.502 (0.487-0.526) vs FGR 0.475 (0.447-0.508); P = 0.005). No differences were found in parieto-occipital sulcus depth between the three study groups.

The objective of this systematic review was to evaluate the efficacy of denture adhesives (DAs) in completely edentulous denture wearers compared to not using DAs.
PubMed, Web of Science, Cochrane Library, and EMBASE were searched from the database inception up to 6 February 2020 for Randomized Controlled Trials (RCTs) involving patients with complete dentures in both arches where the use of DAs was compared to no use of DAs. CTPI-2 research buy A total of 497 abstracts were reviewed, resulting in inclusion of 10 RCTs. Outcomes reported in the included trials were thoroughly reviewed and tabulated. The Cochrane risk of bias tool was used. All 10 studies were assessed at unclear (10%) or high risk of bias (90%). Studies showed DAs improved mainly retention/stability, and masticatory/chewing ability/performance, compared to no adhesives.
Most studies showed favorable results for DAs on retention and stability of complete dentures, masticatory performance, patient's comfort and satisfaction. Due to the heterogeneity of the outcomes, unclear/high risk of bias and small sample sizes, the quality of the evidence was very low. More high-quality research is needed with improved blinding and use of standardized methods to evaluate the efficacy of DAs.

These studies are commonly analyzed using linear mixed models (LMMs), and in this article we consider an extension of the skew-normal/independent LMM, where the error term has a dependence structure, such as damped exponential correlation or autoregressive correlation of order p. The proposed model provides flexibility in capturing the effects of skewness and heavy tails simultaneously when continuous repeated measures are serially correlated. For this robust model, we present an efficient EM-type algorithm for parameters estimation via maximum likelihood and the observed information matrix is derived analytically to account for standard errors. The methodology is illustrated through an application to schizophrenia data and some simulation studies. The proposed algorithm and methods are implemented in the new R package skewlmm.
The aim of this study is to investigate the role of vitamin E in the etiology of premature ovarian insufficiency (POI).
This study included a total of 96 matched cases and controls, including the case group composed of 40 women with POI, and the control group composed of 56 women with normal menstrual cycles. Serum levels of vitamin E (also known as α-tocopherol), total cholesterol, follicle stimulating hormone (FSH), luteinizing hormone (LH) and anti-Müllerian hormone (AMH) were determined. The relationship of α-tocopherol with FSH, LH and AMH levels in women were evaluated using regression models.
We found a negative association of α-tocopherol levels with FSH and LH levels, and a positive correlation between a-tocopherol and AMH levels in the whole study population. In this study, α-tocopherol levels were significantly lower in women with POI than those in women with normal menstrual cycles.
Vitamin E levels showed significantly statistical difference between the POI and control group (P < 0.001).
