This paper introduces some of the available resources, including databases based on diagnostic studies, secondary study resources and bibliography databases, etc. Although some search strategies can be used to identify diagnostic studies, specific search terms and strategies aimed at different databases should also be considered.
Objective To summarize the clinical characteristics of foot and ankle deformities combined with knee and lower limb deformities and evaluate the advantages, clinical outcomes, and considerations of QIN Sihe’s surgical strategy for treating such complex deformities. Methods Between January 2022 and December 2024, 32 patients with foot and ankle deformities combined with knee and lower limb deformities were enrolled. The cohort included 23 males and 9 females, aged 10-67 years (mean, 41.1 years). The main etiologies included post-polio sequelae (20 cases) and congenital limb deformities (3 cases). Deformities were categorized as follows: equinovarus foot (12 cases), equinus foot (2 cases), equinovalgus foot (3 cases), equinus foot with swan-neck deformity (2 cases), calcaneus foot (5 cases), foot valgus (2 cases), knee flexion deformity (14 cases), genu recurvatum (4 cases), genu varum (3 cases), genu valgum (3 cases), lower limb shortening (3 cases), and lower limb external rotation (6 cases). QIN Sihe’s surgical strategies included osteotomies, tendon releases, and tendon transfers for deformity correction, followed by external fixation for residual deformity adjustment and stabilization. Outcomes were assessed using QIN Sihe’s Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction. Results All patients were followed up 8-32 months (mean, 16.5 months). Complications included pin tract infection (1 case, 1 site), ankle pain (2 cases), delayed healing at the proximal tibial osteotomy site (1 case), and anterior talar dislocation (1 case). At last follow-up, insufficient correction of foot deformity was observed in 1 case; both knee and lower limb deformities were corrected, with only mild recurrence of knee flexion deformity in 1 case. The foot/ankle and knee joint function improved. Based on QIN Sihe’s Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction, outcomes were rated as excellent in 30 cases and good in 2 cases, with an excellent-good rate of 100%. Conclusion Foot and ankle deformities combined with knee and lower limb deformities are complex, QIN Sihe’s surgical strategy can achieve satisfactory clinical outcomes for simultaneous correction.
Severe bee stings can trigger a systemic inflammatory response and multi-organ dysfunction, potentially resulting in fatality. Acute kidney injury (AKI) is a frequent complication in patients with severe bee stings, and conventional comprehensive treatment combined with various blood purification therapies is commonly employed in clinical practice to promptly manage the condition and reduce the average hospital stay duration. This article primarily delves into the significance of enhanced clinical nursing care for patients with bee stings-induced AKI undergoing blood purification therapy. Specifically, it underscores the importance of patient education regarding treatment-related considerations, nursing techniques for vascular access during treatment, potential complications, and corresponding nursing interventions.
Acute kidney injury (AKI), as a complex and severe kidney disease, has always been the hotspot of research. The epidemiological research of AKI in China has made significant progress, including initially reports on the domestic incidence of AKI, geographical distribution and risk factors; however, accompanying challenges like AKI prevention and treatment emerge. For improvement of the diagnosis and treatment of the AKI, this article summarizes and analyses the two challenges: early warning biomarkers and AKI treatment strategies, based on new ideas and research progress. The aim is to make Chinese nephrology scholars and specialists realize the focus of AKI prevention and protection of renal function, to standardize the treatment strategy of AKI, and to put forward the direction of future research.
ObjectiveTo summarize the treatment strategies and clinical experiences of 5 cases of giant plexiform neurofibromas (PNF) involving the head, face, and neck. MethodsBetween April 2021 and May 2023, 5 patients with giant PNFs involving the head, face, and neck were treated, including 1 male and 4 females, aged 6-54 years (mean, 22.4 years). All tumors showed progressive enlargement, involving multiple regions such as the maxillofacial area, ear, and neck, significantly impacting facial appearance. Among them, 3 cases involved tumor infiltration into deep tissues, affecting development, while 4 cases were accompanied by hearing loss. Imaging studies revealed that all 5 tumors predominantly exhibited an invasive growth pattern, in which 2 and 1 also presenting superficial and displacing pattern, respectively. The surgical procedure followed a step-by-step precision treatment strategy based on aesthetic units, rather than simply aiming for maximal tumor resection in a single operation. Routine preoperative embolization of the tumor-feeding vessels was performed to reduce bleeding risk, followed by tumor resection combined with reconstructive surgery. Results All 5 patients underwent 1-3 preoperative embolization procedures, with no intraoperative hemorrhagic complications reported. Four patients required intraoperative blood transfusion. A total of 10 surgical procedures were performed across the 5 patients. One patient experienced early postoperative flap margin necrosis due to ligation for hemostasis; however, the incisions in the remaining patients healed without complications. All patients were followed up for a period ranging from 6 to 36 months, with a mean follow-up duration of 21.6 months. No significant tumor recurrence was observed during the follow-up period. Conclusion For patients with giant PNF involving the head, face, and neck, precision treatment strategy can effectively control surgical risks and improve the standard of aesthetic reconstruction. This approach enhances overall treatment outcomes by minimizing complications and optimizing functional and cosmetic results.
Objective To review main obstacles to health care professionals' adherence to clinical practice guidelines (CPGs) by employing the scoping review method and a determinants framework, and to explore the effect of implementation strategies in intervention researches on guideline adherence. Methods The articles published from January 1, 2011 to June 10, 2023 were retrieved from the PubMed, CINAHL, MEDLINE, Embase, Scopus, Cochrane Library, SinoMed, CNKI, WanFang Data and VIP databases. The original literature on the CPGs implementation obstacles and strategies was included, and the primary and secondary screening of the literature were completed by four researchers according to the inclusion and exclusion criteria. The basic characteristics of the literature, the factors affecting the implementation of the CPGs, and the strategies used were extracted. The results were analyzed and summarized using qualitative and quantitative methods. Results A total of 61 articles were included in the scoping review. The factors affecting the implementation of CPGs could be divided into five categories: guidelines themselves, external factors, internal factors, individual factors, and implementation process. The most common implementation obstacles were insufficient knowledge or skills of professionals regarding guidelines (n=21, 34.4%), insufficient necessity of using guidelines according to doctors (n=17, 27.9%), and unreasonable factors within hospital (n=16, 26.2%). The factors that promoted the implementation of CPGs included guidelines based on high-quality evidence (n=5, 8.2%), good department or hospital culture (n=4, 6.6%), convenient accessibility of guideline knowledge and information (n=4, 6.6%), and doctors’ excellent professional ability (n=4, 6.6%). The overall effectiveness of the guideline implementation strategy was 50%. Clinical decision support system (CDSS) could improve the adherence of CPGs. Guideline education or training was one of the most commonly used methods, but the effect of improving guideline compliance was unstable. Conclusion The primary challenges in implementing guidelines include inadequate professional capacity and demand, suboptimal hospital infrastructure and limited resources. However, the obstacles are not absolute. It is recommended to use implementation strategies to improve the absorption and implementation of guidelines, among which CDSS is an effective measure for promoting guideline adherence.
Objective To review the research progress in the construction strategy and application of bone/cartilage immunomodulating hydrogels. Methods The literature related to bone/cartilage immunomodulating hydrogels at home and abroad in recent years was reviewed and summarized from the immune response mechanism of different immune cells, the construction strategy of immunomodulating hydrogels, and their practical applications. Results According to the immune response mechanism of different immune cells, the biological materials with immunoregulatory effect is designed, which can regulate the immune response of the body and thus promote the regeneration of bone/cartilage tissue. Immunomodulating hydrogels have good biocompatibility, adjustability, and multifunctionality. By regulating the physical and chemical properties of hydrogel and loading factors or cells, the immune system of the body can be purposively regulated, thus forming an immune microenvironment conducive to osteochondral regeneration. ConclusionImmunomodulating hydrogels can promote osteochondral repair by affecting the immunomodulation process of host organs or cells. It has shown a wide application prospect in the repair of osteochondral defects. However, more data support from basic and clinical experiments is needed for this material to further advance its clinical translation process.
