A comparison of the efficacy of textured insoles on balance performance in older people with versus without plantar callosities

BackgroundTextured insoles have been suggested to enhance foot sensation, which contributes to controlling upright balance. However, the interaction between plantar callosity and the textured surface has not been studied.Research questionFirstly, to compare the efficacy of textured insoles on balance performance and foot position sense between two groups of older people: one group had plantar callosity, and the other did not. Secondly, to investigate the efficacy of textured insoles within each study group.MethodsThirty older people with a history of falls (15 with plantar callosity and 15 without callosity) participated in this study. All participants underwent assessments of postural sway on a force plate, joint position sensation of the ankle with a slope box, and mobility using the "Timed Up and Go" test under three insole surface conditions: 1) smooth (control), 2) placebo and 3) textured surface. Two-way analyses of variance were used to compare the outcomes of the two groups and three conditions.ResultsOlder people with plantar callosity had worse ankle joint position sense and slower antero-posterior and mediolateral postural sway velocity than their peers who did not have plantar callosity. The textured insoles improved ankle joint position sense and mobility regardless of callus status in the plantar surface of older peoples’ feet. The insole-callosity interaction was not significant for any study outcome.SignificanceTextured insoles could be beneficial to older people with and without callosity as they have shown immediate improvements in ankle joint position sense and mobility.     

血流导向装置治疗大脑中动脉M2段以及远部位动脉瘤的围术期重症护理

目的:探讨血流导向装置治疗大脑中动脉M2段以及远部位动脉瘤的围术期护理方法和价值。方法:选取2021年1月—2021年6月山西省某三级甲等医院神经外科16例大脑中动脉M2段以及远部位动脉瘤病人,均进行血流导向装置Pipeline治疗,总结围术期护理要点。结果:16例病人的手术成功率为100%,术后无相关并发症发生。结论:医务人员需高度关注围术期颅内动脉瘤病人,术前给予病人足够的心理支持和疏导,术中与医生、麻醉师、手术室护士紧密配合,术后密切监测并发症的发生,使病人能够安全度过围术期,顺利康复出院。

Effect of patent ductus arteriosus on the heart in preterm infants

There continues to be controversy on the long‐term effects of a patent ductus arteriosus (PDA) and its management. However, the hemodynamic effects of a large PDA in a preterm infant are well known. This article aims to provide insight into the adaptive changes and remodeling effects of a PDA on the myocardium in preterm infants.     

Detección y manejo de implantación inadecuada de reservorio venoso central en arteria subclavia

We present a case of a female patient with ovarian cancer who had an inadvertent vascular access device implantation in the subclavian artery, being detected after 10 days. She was successfully treated with a covered stent without immediate complications.     

A standing posture support device that reduces laparoscopic surgeons’ occupational lower limb stress

Background: We developed a surgical knee rest (SKR) that can be used to decrease the stress placed on the lower half of the body when surgeons work in the standing position. We tested the effectiveness of this device in the context of laparoscopic surgery.

Material and methods: Five healthy, right-handed male surgeons participated, and we recorded surface electromyography (sEMG) signals from the two heads of the left and right gastrocnemius (Gc) muscles during laparoscopic resections of colorectal cancer. The outcome variable was the percentage of maximum Gc muscle effort generated, reported as percent maximal isometric voluntary contraction (%MVC), and this variable was compared between surgeries performed with and without use of the SKR. Assessment covered the first 100?min of surgery, subdivided into two 50-min periods.

Results: Mean %MVC of the left Gc muscle for the full 100-min test period was significantly decreased when the SKR was used (p?=?.027, vs. SKR not used). Notably, mean %MVC of both Gc muscles was significantly decreased during the first 50?min of surgery (p?=?.008 and p?=?.0046).

Conclusion: The SKR is useful for decreasing physical stress incurred by laparoscopic surgeons when working in the standing position.
