Aims: This study aimed to evaluate the impact of continuous nursing and telehealth education via WeChat in infants with congenital talipes equinovarus (CTEV) undergoing Ponseti therapy on reducing complications, care burden, and improving the quality of life for parents. Methods: This is a single-center retrospective study. From July 2021 to December 2022, 44 CTEV children who undergoing Ponseti treatment in our hospital who received continuous nursing and telehealth education via WeChat (experimental group). In addition, during January 2020 to June 2021, 44 children with CTEV treated with Ponseti in our hospital who received routine nursing and traditional health education were selected as the control group. The incidence of complications, parental care burden and parental quality of life were compared between the two groups. Results: There was no significant difference in the demographic characteristics of patients and parents between the two groups, and the groups were comparable (p > 0.05). The incidence of complications including plaster loosens, plaster falling off, pressure ulcer was significantly lower in the intervention group compared to the control group (p < 0.05). Parents in the intervention group experienced significantly lower care burdens compared to those in the control group (p < 0.05). The quality of life of parents in the intervention group was significantly higher than that for the control group (p < 0.05). There were significant differences in the incidence of complications, the care burden of parents and the quality of life of parents between the two groups. Conclusion: This study found that continuous nursing and telehealth education via WeChat group during Ponsetis treatment of children with CTEV can effectively reduce complications, reduce the care burden of parents and improve the quality of life of parents. This method is simple and convenient, especially worthy of application and promotion in medically underdeveloped areas.

The efficacy of gradual reduction using two-stage traction for developmental dysplasia of the hip in southern China.

Purpose: This study aimed to report the preliminary outcome of gradual reduction (GR) utilizing two-stage traction (TST) compared with traditional traction (TT) in the treatment of developmental dysplasia of the hip (DDH) and to evaluate whether the prognosis of the TST is better than that of TT. Methods: The following information on children diagnosed with DDH who underwent treatment with GR using two-stage traction or traditional traction between June 2016 and August 2017 was collected: sex, age, weight, acetabular index (AI), International Hip Dysplasia Institute (IHDI) classification, femoral head ossification, traction time, reduction quality, and labrum shape in arthrography. The AI, IHDI classification, second operation rate, and incidence of femoral head avascular necrosis (AVN) were analyzed after the final comprehensive 1-year follow-up. Results: In this study, 27 cases (31 hips: 18 left and 13 right) were enrolled, with 18 hips (16 cases) assigned to the TT group and 13 hips (11 cases) assigned to the TST group, with the corresponding average age at diagnosis of 5.56 ± 1.66 and 4.06 ± 1 months (p < 0.001). For both TT and TST groups, the average age at operation was 6.01 ± 1.67 and 65 ± 0.86 months (p = 0.435), the distribution of affected left and right sides was 10/8 and 8/5 hips (p = 1), and the average initial AI was 37.11 ± 3.26 and 36.77 ± 4.34 (p = 0.804), respectively. IHDI classification III/IV was observed in 15/3 and 11/2 hips, respectively (p = 1). Femoral head ossification was present in 6/18 hips in the TT group and 2/13 hips in the TT group (p = 0.412). The total traction time was 13.22 ± 2.6 days for the TT group and 49.23 ± 25.77 days for the TST group (p < 0.001). After GR, IHDI classification III/IV was observed in 9/9 and 12/1 hips, respectively (p = 0.02). AVN was present in 5/18 hips in the TT group and 0/13 hips in the TST group (p = 0.048), while the need for a second operation was approved in 5/18 hips in the TT group and 1/13 hips in the TST group (p = 0.359) at the final follow-up. Conclusions: Two-stage traction can significantly decrease the ratios of IHDI classifications III and IV and the incidence of AVN compared to traditional traction; also, it significantly reduces the total traction time.

Effects of eyeshades in sleep quality and pain after surgery in school-age children with supracondylar humeral fractures.

Objective: This study aimed to explore the effects of eye masks on the sleep quality and pain of children over 5 years old with humeral supracondylar fracture after surgery. Methods: Fifty children with humeral supracondylar fracture who underwent closed reduction and percutaneous pinning (CRPP) in the Pediatric orthopaedic Department of a provincial hospital in China from February 2020 to December 2021 were selected. The children were randomly divided into the experimental group (n = 25) and the control group (n = 25). Children in the control group were given routine sleep care, and the children in the experimental group were given a sleep intervention with eye masks for three nights after surgery. The Pittsburgh Sleep Quality Index was used to evaluate the sleep quality of the children. The Children's Pain Behaviour Scale was used to evaluate the pain of the children. Results: After three nights of receiving the eye mask intervention, the children in the experimental group had significantly lower sleep quality scores than those in the control group; the difference was statistically significant (p < 0.05), and the children in the experimental group had higher sleep quality. The experimental group's pain scores were significantly lower than the control group's, and the difference was statistically significant (p < 0.05), and the children in the experimental group experienced less post-operative pain. Conclusions: Eye masks are a simple, safe and economical intervention, that is beneficial for improving the sleep quality and reducing pain in children over 5 years old with humeral supracondylar fracture after closed reduction and percutaneous pinning. It can be used as a reference and basis for clinical pain relief and sleep quality after surgery for supracondylar fractures of the humerus in children.

The causal relationship between abdominal obesity and lower bone mineral density: A two-sample mendelian randomization study.

Aims: The purpose of this study was to assess the causal effect of abdominal obesity on bone mineral density by two-sample Mendelian randomization (MR). Methods: Abdominal obesity was chosen as exposure in this study. Single nucleotide polymorphisms, extracted from Genome-wide association analysis (GWAS) data, which are closely associated with waist circumference (WC), hip circumference (HC), and waist-to-hip ratio (WHR) were used as instrumental variables to perform MR studies. Different site bone mineral density, such as total bone mineral density (TBMD) and forearm bone mineral density (FBMD) were chosen as outcomes. Inverse variance weighted (IVW) was used as the primary method to assess this causality. Results: According to the IVW method (ß = -0.177; 95% CI = -0.287, -0.067; p = 1.52 × 10-3), WC had a negative causal relationship with TBMD, besides, with one standard deviation (SD) higher in HC, there was a 0.195 SD decrease in TBMD (95% CI = -0.279, -0.110; p = 6.32 × 10-6), and with an increase of one SD in HC was related to a decrease of 0.312 SD in FBMD analyzed by the IVW. Conclusion: This study showed that abdominal obesity has a negative effect on bone mineral density.

[Research progress of two-stage revision for periprosthetic joint infection after hip and knee arthroplasties].

OBJECTIVE: To summarize the research progress of two-stage revision for periprosthetic joint infection (PJI) after hip and knee arthroplasties. METHODS: The related literature on two-stage revision for PJI was summarized, and the new progress in the choice of spacers, systemic antibiotic therapy, and risk factors were analyzed. RESULTS: Two-stage revision is a common way to treat infection after hip and knee arthroplasties. The types of spacers used in the one-stage operation are diverse and each has its own advantages and disadvantages. Non-articular spacers are mainly used for the patients with poor soft tissue conditions around the joints and severe bone defects. But the joint mobility is not good after the placement of the spacer. Articular spacers can restore the affected joint movement after operation, which is beneficial to the joint mobility after two-stage operation. The use of antibiotics is an indispensable part of the treatment process, and the effectiveness of short-term antibiotic treatment is similar to long-term treatment. Identifying the relevant risk factors that influence the prognosis of the two-stage revision can help preoperative management and reduce the recurrence rate of infection. CONCLUSION: There are still controversies about the choice of spacers and systemic antibiotic therapy during the two-stage revision and treatment of PJI. The factors affecting the prognosis of the two-stage revision need to be explored and the further high-quality research is needed.
