BACKGROUND The preservation of fertility and integrity of the reproductive organs has increasingly been of concern to most women with adenomyosis. Adenomyomectomy is conservative surgery that is now widely applied; however, relapse is a serious problem after the operation. Postoperative treatment, such as gonadotropin-releasing hormone agonist (GnRHa) has been suggested to result in reducing the rate of disease recurrence. However, there is still a lack of evidence from randomized clinical trials examining the efficacy of GnRHa in decreasing the postoperative recurrence rate. METHOD/DESIGN Relapse after conservative surgery combined with triptorelin acetate versus conservative surgery only in women with focal adenomyosis is a multicenter, prospective, randomized controlled trial. The primary outcome is relapse assessed using a visual analogue scale (VRS) and numeric rating scale (NRS), pictorial blood loss assessment chart (PBAC) score, and the size of the uterus and the lesion as measured by two/three-dimensional color doppler ultrasonography (2D/3D-CDUS) or magnetic resonance imaging (MRI). read more The secondary outcomes include quality of life, clinical pregnancy, ovarian reserve, adverse events, assessment by the Short Form (36) Health Survey and Female Sexual Function index, serum follicle-stimulating hormone, estradiol levels, and anti-Muellerian hormone and so on. All these indexes are measured at 3, 6, 12, 18, 24, 30, and 36 months after conservative surgery. DISCUSSION The result of this large, multicenter randomized trial will provide evidence for one of the strategies of long-term management in focal adenomyosis after conservative operation.

Supportive and sensitive parenting is one of the strongest predictors of positive emotional, social and behavioral outcomes for the child. Knowledge is needed about how to detect and support vulnerable families already during pregnancy and in the postnatal period. The aim of this study is to assemble and evaluate an interdisciplinary cross-sectoral intervention to promote maternal sensitivity among women with psychological or social vulnerabilities. METHODS/DESIGN This randomized controlled trial tests the efficacy of an intervention program in the perinatal period compared to care as usual in enhancing maternal sensitivity in a group of psychologically or socially vulnerable women in the Capital Region of Denmark. The intervention consists of four components 1) detecting symptoms of mental illness in vulnerable pregnant women and initiating treatment if indicated, prenatal risk profiles among an identified group of psychosocial vulnerable women important for early screening and point to effective preventive interventions that can support women in the perinatal period, increase maternal sensitivity and promote positive child development -starting before the child is born.

It is not clear whether and how exosomes modulate Aβ neurotoxicity in Alzheimer's disease (AD). We show here that brain tissue and serum from the transgenic mouse model of familial AD (5xFAD) and serum from AD patients contains ceramide-enriched and astrocyte-derived exosomes (termed astrosomes) that are associated with Aβ. In Neuro-2a cells, primary cultured neurons, and human induced pluripotent stem cell-derived neurons, Aβ-associated astrosomes from 5xFAD mice and AD patient serum were specifically transported to mitochondria, induced mitochondrial clustering, and upregulated the fission protein Drp-1 at a concentration corresponding to 5 femtomoles Aβ/L of medium. Aβ-associated astrosomes, but not wild type or control human serum exosomes, mediated binding of Aβ to voltage-dependent anion channel 1 (VDAC1) and subsequently, activated caspases. Aβ-associated astrosomes induced neurite fragmentation and neuronal cell death, suggesting that association with astrosomes substantially enhances Aβ neurotoxicity in AD and may comprise a novel target for therapy.The clinical, social and economic burden of cardiovascular disease (CVD) associated with diabetes underscores an urgency for understanding the disease aetiology. Evidence suggests that the hyperglycaemia associated with diabetes is, of itself, causal in the development of endothelial dysfunction (ED) which is recognised to be the critical determinant in the development of CVD. It is further recognised that epigenetic modifications associated with changes in gene expression are causal in both the initiation of ED and the progression to CVD. Understanding whether and how hyperglycaemia induces epigenetic modifications therefore seems crucial in the development of preventative treatments. A mechanistic link between energy metabolism and epigenetic regulation is increasingly becoming explored as key energy metabolites typically serve as substrates or co-factors for epigenetic modifying enzymes. Intriguing examples are the ten-eleven translocation and Jumonji C proteins which facilitate the demethylation of DNA and histones respectively. These are members of the 2-oxoglutarate-dependent dioxygenase superfamily which require the tricarboxylic acid metabolite, α-ketoglutarate and molecular oxygen (O2) as substrates and Fe (II) as a co-factor. An understanding of precisely how the biochemical effects of high glucose exposure impact upon cellular metabolism, O2 availability and cellular redox in endothelial cells (ECs) may therefore elucidate (in part) the mechanistic link between hyperglycaemia and epigenetic modifications causal in ED and CVD. It would also provide significant proof of concept that dysregulation of the epigenetic landscape may be causal rather than consequential in the development of pathology.
