“…We wrapped the pretrimmed SHEs around the aneurysm and achieved in situ seamless sleeving (Supplementary Movie 2). Progressive fibrosis around SHEs will theoretically protect aneurysms from the expansion and rupture after degradation, achieving the purpose of limitation and elimination of residual foreign bodies 39 . SHE0.5 exhibited a better limitation effect for aneurysms than did the SHE1, while the SHE2 unexpectedly caused vessel injury in the presence of collateral circulation instead.…”

The unique properties of self-healing materials hold great potential in the field of biomedical engineering. Although previous studies have focused on the design and synthesis of self-healing materials, their application in in vivo settings remains limited. Here, we design a series of biodegradable and biocompatible self-healing elastomers (SHEs) with tunable mechanical properties, and apply them to various disease models in vivo, in order to test their reparative potential in multiple tissues and at physiological conditions. We validate the effectiveness of SHEs as promising therapies for aortic aneurysm, nerve coaptation and bone immobilization in three animal models. The data presented here support the translation potential of SHEs in diverse settings, and pave the way for the development of self-healing materials in clinical contexts.

“…4 Parent artery narrowing has been reported after wrapping procedures with cotton gauze 9 and plastic 7,8 or human-fibrin 12 adhesives in single cases or small case series. Similar to our series, Yoon et al used cotton gauze and human fibrin adhesives 12 and described neuroimaging findings in 5 cases with muslinoma, and found parent artery narrowing in 2, which was associated with an ischemic stroke in 1 of their 5 patients.…”

Object. Reinforcement of intracranial aneurysms (IAs) by wrapping or coating is a well-established therapeutic approach to those IAs not amenable to any other definitive treatment, but has been associated with complications such as parent artery narrowing, granuloma formation, and ischemic stroke. The goal of this study was to systematically investigate cerebrovascular complications following this procedure.Methods. The authors' hospital database was searched for all patients who underwent wrapping or coating of IAs with cotton gauze and human fibrin adhesives between October 2006 and October 2011. The follow-up records of these patients were extracted, including regular clinical visits and vascular imaging.Results. Five hundred sixty-seven patients were treated for IAs over the 5-year period: 303 patients underwent endovascular strategies and 264 underwent craniotomies. Wrapping or coating of IAs was performed in 20 patients (3.5%). Parent artery narrowing occurred in 5 (25%) of the 20 patients and was associated with major ischemic strokes in 4 patients and severe headache in another. Ischemic strokes were associated with parent artery narrowing, which occurred early postoperatively in 2 patients or was a consequence of granuloma formation in 2 patients 1 and 2 months after the procedure, respectively.Conclusions. These data should add to the awareness of significant cerebrovascular complications following wrapping or coating of IAs with cotton gauze and human fibrin adhesives and indicate that major ischemic strokes need to be included in the risk/benefit considerations during decision making for such treatment strategies. Patients who receive IA wrapping should be monitored and followed up closely for arterial narrowing and granuloma formation.

“…Quantitative studies in Iran have addressed the nutritional status of patients with osteoporosis. A study conducted in the northwest region of Iran showed a significant difference between dietary intake of nutrients and the recommended dietary allowance 91 . For example, adequate intake of calcium, vitamin D, and vitamin K was observed only in 7.2%, 3.1%, and 42.3% of cases, respectively 92 .…”

Introduction: Osteoporosis falls among the major general health issues, specifically in the elderly, and is a widespread disease these days. According to various studies, good nutrition plays a significant role in osteoporosis prevention and treatment. The aim of this study was to conduct an extensive literature review on the effects of different nutrients to understand how macronutrients, micronutrients, and non-nutritive substances affect bone health. Methodology: To find relevant studies, the main keyword “osteoporosis” was searched in combination with “zinc,” “vitamin K,” “phosphorus,” “vitamin D,” “calcium,” “lipid,” “protein,” and “phytoestrogens” in PubMed (MEDLINE), Web of Science, SID, and Iran Medex databases. Findings: The most important element for bone health is calcium, which has a direct link to the bone mass density (BMD). In the case of calcium deficiency, high phosphorus content can damage bone tissue. The acceptable ratio of phosphorus to calcium is 0.5-1.5:1. Vitamin D is another important nutrient for bones; serum levels of vitamin D less than 20 ng/ml reduce bone density and increase the risk of fracture. High protein intake results in calcium excretion and loss of bone mass. In addition, calcium deficiency increases the risk of osteoporosis, specifically in the elderly. According to the literature, there is an inverse correlation between saturated fats and BMD. Vitamin K and magnesium deficiencies are correlated with BMD reduction and increased risk of osteoporosis. Copper and zinc are used as co-factors in the formation of collagen and elastin, and in mineralization of bone. As a result, deficiency of these elements may disrupt the process of incorporating minerals into the bone matrix. Conclusion: Good nutrition may play a significant role in osteoporosis prevention and treatment. Indeed, a healthy diet containing calcium (1,200 mg/day); vitamin D (600 IU); and certain amounts of protein, magnesium, and vitamin K can contribute greatly to bone health.
