Controlled release Ibu-cryobarriers for the prevention of post-operative adhesions: In-vitro/in-vivo comparative study

Publication date: 30 June 2019Source: International Journal of Pharmaceutics, Volume 565Author(s): Noha S. El-Salamouni, Mennatallah A. Gowayed, Gihan S. LabibAbstractPost-operative adhesion is a common cause of several complications including intestinal obstruction, chronic pelvic pain and/or infertility. Adhesions are fibrous bands that result from the inflammatory reactions due to peritoneum damage. The current study focused on designing an effective anti-inflammatory loaded barrier for the prevention of post-operative adhesions. The proposed method is based on the use of polyvinyl alcohol (PVA), cryobarrier loaded with Ibuprofen (Ibu). Anti-adhesive Ibu-cryobarriers were prepared in different forms, and subjected to in-vitro evaluation comprising; drug release rate, maximum swelling index, morphological examination using scanning electron microscope (SEM), fourier-transform infrared spectroscopy (FTIR) and mechanical properties. Optimized cryobarriers were further investigated for their in-vivo effectiveness in preventing post-operative adhesions in female Sprague-Dawley rats. All formulations showed appropriate physical and morphological characteristics, in-vitro controlled sustained drug release profiles during a period of seven days with acceptable maximum swelling index. Invivo, all cryobarriers were equivalent to each other concerning serum or tissue parameter. However, morphological and histopathological evaluations revealed that both xerocryogel and lyophilized cry...

We describe the most highly recommended generic and disease-specific PRO tools in SCD and discuss the challenges of incorporating them in clinical practice. EXPERT OPINION: PRO measures are essential to incorporate into SCD clinical trials either as primary or secondary outcomes. The use of PRO measures in SCD facilitates a patient-centered approach, which is likely to lead to improved outcomes. Significant challenges remain in adapting PRO tools to routine clinical use and in developing countries. PMID: 33034214 [PubMed - as supplied by publisher]

CONCLUSIONS: Immunohistochemistry seems to be a promising option not only in clinical recognition, but also in the selection and monitoring of treatment effects. However, these methods have not yet recommended for routine clinical use. PMID: 33032462 [PubMed - as supplied by publisher]

CONCLUSIONS: Considering the low number of university students disclosing sexual assaults to health professionals or support services, the results of this survey suggest more work is needed to facilitate greater disclosures to health professionals enabling victims to access the services they need regardless of alcohol use.

In this study, a link between mitochondrial changes and infant temperament has also been suggested. Maternal psychosocial stress and lifetime trauma have been associated with decreased mitochondrial DNA copy number in the placenta (115, 116).IndividualityChronic stress links changes in the epigenetic landscape with health conditions (117). Different cell types are characterized by distinct patterns of gene expression due to developmental, environmental, physiological, and pathological reasons (117). Epigenetic mechanisms affect gene function in a dynamic way as a result of different environmental exposures during fetal dev...

How many times can you begin again? That's what I asked myself as I entered the Hospital for Special Surgery, just three weeks after my first lumbar spine epidural steroid injection and SI joint procedure. I was late. I spent two hours stuck in traffic during my drive from New Jersey to New York. So I was frazzled and my thoughts were scattered when I arrived. Yet, that question, can I start over again after another procedure rattled around in my head. My entire adulthood has been a long and winding road, at least medically. At 17, a sparse menstrual cycle, joint pain and spontaneous fever left doctors scratching their he...

Conclusion: there is no increased risk of doing the lymph node dissection early on.   Dr. Eggener-CON   Basics Lymph node dissections rarely done, even for large tumors, because there is no proven therapeutic or staging benefit for low risk patients.  A Mayo study revealed no data showing therapeutic benefit in high risk patients.  For clinically node negative high risk patients, there is staging value but no proven therapeutic benefit. Rate of positive nodes is associated with stage and grade; the higher the stage and grade, the more likely there will be positive nod...
