Background Extracellular vesicles(EVs) present in oviductal(OF) and uterine fluid(UF) have been shown to enhance bovine embryo quality during in vitro culture by reducing lipid contents and modulating lipid metabolism-related genes(LMGs), while also influencing cell proliferation, suggesting their involvement on the regulation of different biological pathways. The regulation of signaling pathways related to cell differentiation, proliferation, and metabo-lism is crucial for early embryo development and can determine the success or failure of the pregnancy. Bioactive molecules within EVs in maternal reproductive fluids, such as micro RnAs(miRnAs), may contribute to this regulatory process as they modulate gene expression through post-transcriptional *** This study evaluated miRnA cargo in OF-EVs from the early luteal phase and UF-EVs from the mid-luteal phase, coinciding with embryo transit within oviduct and uterus in vivo, and its possible influence on LMGs and sign-aling pathways crucial for early embryo development. A total of 333 miRnAs were detected, with 11 exclusive to OF, 59 to UF, and 263 were common between both groups. From the 20 differentially expressed miRnAs, 19 up-regulated in UF-EVs(bta-miR-134, bta-miR-151-3p, bta-miR-155, bta-miR-188, bta-miR-181b, bta-miR-181d, bta-miR-224, bta-miR-23b-3p, bta-miR-24-3p, bta-miR-27a-3p, bta-miR-29a, bta-miR-324, bta-miR-326, bta-miR-345-3p, bta-miR-410, bta-miR-652, bta-miR-677, bta-miR-873 and bta-miR-708) and one(bta-miR-148b) in OF-EVs. These miRnAs were predicted to modulate several pathways such as Wnt, Hippo, MAPK, and lipid metabolism and degradation. Differ-ences in miRnAs found in OF-EVs from the early luteal phase and UF-EVs from mid-luteal phase may reflect differ-ent environments to meet the changing needs of the embryo. Additionally, miRnAs may be involved, particularly in the uterus, in the regulation of embryo lipid metabolism, immune system, and *** Our study su

Background: Minimally invasive transforaminal lumbar interbody fusion (MI TLIF) is a widely known and performed technique, however its versatility among different physicians continues to hinder its replication and results. Therefore, this study aimed to provide a step-by-step surgical guide to perform a safe MI-TLIF, based on the results obtained in patients operated on by a single surgeon over a period of 12 years. Patients and methods: A retrospective, single center, longitudinal, and observational cohort study was conducted with 931 patients who underwent MI TLIF by a single surgeon between 2010 and 2022 using the technique described on this paper, each with a minimum follow-up of 12 months. Criteria included Schizas classification, listhesis according to Meyerding classification, number of levels treated, cage size, and complications (screw repositioning or cerebrospinal fluid leak). Patient clinical outcomes were assessed using the Oswestry Disability Index (ODI), Visual Analog Scale (VAS) for pre- and postoperative radicular pain. Thin slice CT scans were used to assess the progression of the fusion using the Bridwell classification. In the statistical analysis, percentages, median, and interquartile range (IQR) were calculated. Results: nine hundred and thirty one patients underwent MI TLIF using the technique described, eight hundred and eighty (94.5%) had a single level treated and fifty one (5.5%) had a 2 level procedure (982 levels), an 8mm cage was placed on five hundred and seventeenlevels (52.7%), six hundred and sixty three levels(67.6%) achieved grade I fusion, two hundred and sixty six levels (27.1%) achieved grade II fusion, 52 levels (5.3) achieved grade III fusion and one level (0.1) achieved a grade IV fusion or non-union. Revision surgery was performed on 3 patients (0.3%) for screw repositioning, cerebrospinal fluid leak was present on 2 patients during surgery and treated before closure. VAS scores and ODI were improved at 12 months postop (V

The Impact of Psychosocial Influences on Chronic Wound Healing

Open Journal of Medical Psychology 2024年第3期13卷 39-57页

作者： Kelly Frasier Vivian Li Sara Christoforides Kathleen Daly Alexandra Loperfito karina Stech Milena Dragovic nuvance Health/Vassar Brothers Medical Center Poughkeepsie NY USA Lake Erie College of Osteopathic Medicine New York NY USA Medical College of Georgia Augusta University Augusta GA USA Edward Via College of Osteopathic Medicine Blacksburg VA USA Lewis Katz School of Medicine Temple University Philadelphia PA USA College of Osteopathic Medicine California Health Sciences University Clovis CA USA

This comprehensive review explores the intricate dynamics between psychosocial factors and chronic wound healing processes, specifically focusing on prevalent conditions such as pressure ulcers, diabetic foot ulcers, and venous leg ulcers. By examining the roles of psychiatric conditions, including depression, anxiety, and post-traumatic stress disorder (PTSD), this paper illuminates how these factors intricately influence wound healing dynamics, including mechanisms of pain perception and inflammatory responses. Furthermore, we evaluate the effectiveness of integrated biopsychosocial interventions, which encompass a holistic approach to wound care, thereby enhancing healing outcomes for dermatology patients. Future studies should focus on investigating the specific psychosocial determinants that significantly influence wound healing, exploring novel therapeutic strategies, and implementing personalized interventions to meet the unique needs of each patient. Such endeavors hold promise in advancing the fields of psychodermatology and wound management, fostering a deeper understanding and application of psychosocial considerations in dermatological care.

Psychiatric Sequelae of Chronic Pruritic Dermatoses

Open Journal of Medical Psychology 2024年第2期13卷 25-38页

This comprehensive review investigates the significant psychological impact and profound psychological comorbidities found in individuals suffering from chronic pruritic dermatoses, including atopic dermatitis, chronic urticaria, and prurigo nodularis. Highlighting the complex, reciprocal relationship between pruritus and psychiatric conditions such as depression, anxiety, and sleep disturbances, this paper elucidates the comprehensive impact of dermatological disorders on the skin in addition to the far-reaching effects on an individual’s psychological well-being. By evaluating the efficacy of integrated psychodermatological interventions, including cognitive behavioral therapy, mindfulness practices, pharmacological treatments, and innovative telepsychiatry and digital health solutions, this review aims to lay the foundation for a more holistic approach to treatment of concurrent dermatological and psychiatric conditions. Future research endeavors should delve deeper into the mechanistic foundation of the pruritus-psychiatry interface, the refinement of tailored treatment strategies, and the evaluation of long-term patient outcomes. In doing so, this review seeks to contribute to the optimization of patient care and well-being, underscoring the pivotal role of addressing both dermatological and psychological needs in achieving comprehensive health outcomes.
