Effect of open versus minimally invasive surgery on postoperative wound site complications in patients with recurrent shoulder instability: A meta-analysis.

The Latarjet procedure is the accepted method of operation for patients with anterior shoulder instability. However, as arthroscopy becomes more and more popular, more and more patients are being treated with minimally invasive techniques for the treatment of anteriorly unstable shoulder. This research aims to compare the curative effects of arthroscopic Latarjet (AL) and open Latarjet (OL) on postoperative anterior shoulder instability. Our hypothesis is that arthroscopy will produce better results than open surgery. During the study, a review was conducted on four main databases, including EMBASE and Cochrane Library. Six cohort studies comparing AL with OL in the treatment of anterior shoulder instability were included. Patients who were operated by open technique up to 2023 were referred to as OL and those who underwent arthroscopic surgery were referred to as AL. Comparison was made between the two methods of operation. The statistical analysis was done with RevMan 5.3. The analysis included Visual Analogue Scale (VAS) scores and postoperative wound infections. A total of six studies were included for analysis under inclusion and exclusion criteria. There were 798 patients, 476 was AL group and 322 was OL group. No statistical significance was found on the incidence of postoperative wound infection in the patients who underwent the Latarjet procedure (odds ratio [OR], 1.43; 95% confidence interval [CI], 0.28-7.31; p = 0.67) and the VAS score after surgery (mean difference [MD], 0.70; 95% CI, -0.67 to 2.06; p = 0.32) for patients. However, it has now been demonstrated that arthroscopy is a safe and viable alternative. The only drawback of arthroscopic Latarjet surgery is probably that it has a long learning curve and requires a lot of practice from the surgeon.

Ruscogenin Attenuates Lipopolysaccharide-Induced Septic Vascular Endothelial Dysfunction by Modulating the miR-146a-5p/NRP2/SSH1 Axis.

Introduction: Endothelial dysfunction (ED) is associated with the progression of sepsis. Ruscogenin (RUS) has shown considerable efficacy in treating ED and sepsis. In the current study, the effects of RUS on sepsis-induced ED were assessed, and the mechanism was explored by focusing on the interactions of RUS with miRs. Methods: Sepsis was induced in mice and in human umbilical vein endothelial cells (HUVECs) using LPS method. Expression profile of miRs responding to sepsis was determined. Symptoms associated with sepsis and ED were examined after treatment with RUS. Changes in mouse survival, arterial structure, systemic inflammation, cell viability, apoptosis, and the miR-146a-5p/NRP2/SSH1 axis were analyzed. Results: Based on the microarray results, miR-146a-5p was selected as the therapeutic target. RUS improved survival rates and arterial structure, suppressed proinflammatory cytokines, down-regulated miR-146a-5p, and up-regulated NPR2 and SSH1 in septic mice. In HUVECs, RUS increased cell viability, suppressed apoptosis, inhibited inflammation, downregulated miR-146a-5p, and increased NRP2 and SSH1 levels. The re-induction of miR-146a-5p-5p impaired the protective effects of RUS on HUVECs. Discussion: Effects of RUS on sepsis-induced impairments in endothelium relied on the suppression of miR-146a-5p.

Elastic fixation of mallet finger fractures using two K-wires: A case report of a new fixation technique.

RATIONALE: Mallet finger fracture is a common sports-related injury that may lead to the tearing of extensor tendon and protrusion of a bony fragment located at the base of the distal phalanx. We affirmed that the elastic fixation of with two K-wires technique is a good method to deal with Mallet Finger fractures that fractures could gain effective fixation than the conventional treatment method and avoid surgical incision complication PATIENT CONCERNS:: We reported a 33-year-old female patient came to our hospital complaining of mild pain, swelling and her right little finger was deformed because of sport's injury. DIAGNOSIS: Acute mallet finger fracture type IV B according to Doyle classification of mallet injuries. INTERVENTIONS: We performed an emergency operation for the elastic fixation of the mallet finger fractures with two K-wires. OUTCOMES: After the surgery, the patient showed functional recovery. No evidence of recurrence was noted 6 months after the operation, and the patient showed no symptoms of sports-related injuries. LESSONS: We discuss the clinical diagnosis, treatment, and follow-up of the patient and suggest that elastic fixation with two K-wires is a good method to treat mallet finger fractures.

Highly Stretchable and Compressible Cellulose Ionic Hydrogels for Flexible Strain Sensors.

Stretchable and compressible hydrogels based on natural polymers have received immense considerations for electronics. The feasibility of using pure natural polymer-based hydrogels could be improved if their mechanical behaviors satisfy the requirements of practical applications. Herein, we report highly stretchable (tensile strain ∼126%) and compressible (compression strain ∼80%) cellulose ionic hydrogels (CIHs) among pure natural polymer-based hydrogels including cellulose, chitin, and chitosan via chemical cross-linking based on free radical polymerization of allyl cellulose in NaOH/urea aqueous solution. In addition, the hydrogels have good transparency (transmittance of ∼89% at 550 nm) and ionic conductivity (∼0.16 mS cm-1) and can be worked at -20 °C without freezing and visual loss of transparency. Moreover, the CIHs can serve as reliable and stable strain sensors and have been successfully used to monitor human activities. Significantly, the various properties of hydrogel can be controlled through rationally adjusting the chemically cross-linked density. Our methodology will prove useful in developing the satisfied mechanical and transparent CIHs for a myriad of applications in flexible electronics.

A Cyclooxygenase-2 Inhibitor Reduces Vascular Wall Thickness and Ameliorates Cognitive Impairment in a Cerebral Small Vessel Diseases Rat Model.

Cerebral small vessel disease (CSVD) is a group of diseases that originate from changes in cerebral small vessels and that cause many conditions, such as cognitive impairment. However, there is no effective therapy for these diseases. Recent studies have suggested that inflammation is associated with this disease. Cyclooxygenase-2 (cox-2) is an inflammatory mediator; however, whether a cox-2 inhibitor could protect against the CSVD progression remains unknown. In the present study, stroke-prone spontaneously hypertensive rats (SHRsp) were used as a model of CSVD, and Sprague Dawley (SD) rats served as the control. SHRsp were treated with the cox-2 inhibitor celecoxib or vehicle. The Morris water maze test was performed, and vascular morphometry and the expression of collagen I and fibronectin were examined in cerebral small vessels and cerebral tissue. The results revealed that thickened small veesel walls, increased expression of collagen I and fibronectin and impaired cognitive function in SHRsp compared with SD rats. Additionally, celecoxib significantly down-regulated the expression of collagen I and fibronectin, attenuated the increase in vascular wall thickness and ameliorates the cognitive impairment. Our study indicated that this cox-2 inhibitor may serve as a promising candidate for the pharmacological intervention of CSVD.
