Factors Associated with Re-Displacement after Nonsurgical Treatment of Distal Radius Fractures in Adults: A Retrospective Study.

OBJECTIVE: Closed reduction combined with external fixation is a frequently utilized approach for treating distal radial fractures in adults. Nonetheless, the potential for re-displacement following external fixation remains. Analyzing the factors influencing re-displacement after nonsurgical treatment of distal radial fractures in adults is vital for preventing re-displacement and making prognostic assessments. METHODS: A retrospective analysis was performed on 884 patients who underwent nonsurgical treatment for distal radius fractures in the reduction room of the Orthopedics and Traumatology Department of Integrated Traditional Chinese and Western Medicine at Tianjin Hospital, Tianjin, China, between July 2019 and December 2022. Patients were categorized into two groups, namely displaced and nondisplaced, based on radiographic outcomes. Factors affecting fracture re-displacement were examined, including sex, age, side, AO/OTA type, external fixation, and radiographic outcomes at pre-reduction and immediate reduction. Logistic regression analysis was employed to identify the risk factors for fracture re-displacement, and ROC curves were constructed. RESULTS: Among the 884 patients, 563 (63.69%) experienced re-displacement after fracture reduction. There were no statistically significant differences (p > 0.05) between the two groups in terms of gender, external fixation method, and palmar tilt angle at pre-reduction and immediate reduction, while significant differences (p < 0.05) were observed in age, side, AO/OTA type, and radial inclination, radial length, and radiographic outcomes of ulnar variance at pre-reduction and immediate reduction. Multifactorial logistic regression analysis revealed that age (odds ratio [OR] = 1.027, p < 0.001), AO/OTA type (OR = 2.327, p = 0.005), ulnar variance at pre-reduction (OR = 1.142, p = 0.048), and ulnar variance at immediate reduction (OR = 1.685, p < 0.001) were significant factors (p < 0.05) associated with re-displacement following nonoperative treatment of adult distal radius fractures. For patients aged ≥60 years, the amount of missing radiographic outcomes was positively correlated with age. The receiver operating characteristic curve demonstrated that age ≥65.5 years, ulnar variance >3.26 mm at pre-reduction, and ulnar variance >2.055 mm at immediate reduction were high-risk factors for fracture re-displacement. CONCLUSIONS: Nonsurgical treatment of distal radius fractures exhibits a higher rate of re-displacement. Age, AO/OTA type, pre-reduction, and immediate reduction ulnar variance are key factors predicting fracture re-displacement.

A systematic review and meta-analysis of nursing effect of fast-track recovery surgery on patients undergoing total endoscopic resection of esophageal cancer: fast-track recovery surgery vs. nursing care as usual.

Background: Esophageal cancer (EC) is the 6th leading cause of cancer-related deaths worldwide, and the morbidity and mortality of EC have continued to increase in recent years. The results of the clinical application of the Fast-track recovery surgery (FTS) concept in nursing interventions for EC patients after total endoscopic esophagectomy are unconvincing. This study sought to evaluate the nursing effect of the fast-track recovery surgical nursing model on patients with EC after total cavity endoscopic esophagectomy. Methods: We searched for articles on case-control trials about nursing interventions after total endoscopic esophagectomy. The search time was set from January 2010 to May 2022. The data were independently extracted by 2 researchers. RevMan5.3 statistical software (Cochrane) was used to analyze the extracted data. All the articles included in the review were assessed for risk of bias using the Cochrane Handbook 5.3 (https://training.cochrane.org/). Results: Ultimately, 8 clinical controlled trials, comprising 613 cases, were identified. A meta-analysis was conducted of the extubation times, and the results showed that the study group's extubation times were remarkably shorter. In relation to the exhaust times, the study group had significantly shorter exhaust times than control group (P<0.05). In relation to the time, it took patients to leave bed, patients in the study group left bed in a considerably shorter time compared with controls (P<0.00001). In relation to the hospitalization time, a remarkable reduction in the length of hospital stay was observed in the study group (P<0.00001). The analysis of the funnel plots showed a small number of asymmetries, suggesting that the number of articles included was small due to the heterogeneity of the studies (P<0.00001). Conclusions: FTS care is effective at accelerating patients' postoperative recovery. This model of care needs to be further validated in the future by higher-quality and longer follow-up studies.

Berberine attenuates sunitinib-induced cardiac dysfunction by normalizing calcium regulation disorder via SGK1 activation.

Sunitinib (SNT)-induced cardiotoxicity is associated with abnormal calcium regulation caused by phosphoinositide 3 kinase inhibition in the heart. Berberine (BBR) is a natural compound that exhibits cardioprotective effects and regulates calcium homeostasis. We hypothesized that BBR ameliorates SNT-induced cardiotoxicity by normalizing the calcium regulation disorder via serum and glucocorticoid-regulated kinase 1 (SGK1) activation. Mice, neonatal rat cardiomyocytes (NRVMs), and human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) were used to study the effects of BBR-mediated SGK1 activity on the calcium regulation disorder caused by SNT as well as the underlying mechanism. BBR offered prevention against SNT-induced cardiac systolic dysfunction, QT interval prolongation, and histopathological changes in mice. After the oral administration of SNT, the Ca2+ transient and contraction of cardiomyocytes was significantly inhibited, whereas BBR exhibited an antagonistic effect. In NRVMs, BBR was significantly preventive against the SNT-induced reduction of calcium transient amplitude, prolongation of calcium transient recovery, and decrease in SERCA2a protein expression; however, SGK1 inhibitors resisted the preventive effects of BBR. In hiPSC-CMs, BBR pretreatment significantly prevented SNT from inhibiting the contraction, whereas coincubation with SGK1 inhibitors antagonized the effects of BBR. These findings indicate that BBR attenuates SNT-induced cardiac dysfunction by normalizing the calcium regulation disorder via SGK1 activation.

Phylogenomics and Comparative Genomics Highlight Specific Genetic Features in Ganoderma Species.

The Ganoderma species in Polyporales are ecologically and economically relevant wood decayers used in traditional medicine, but their genomic traits are still poorly documented. In the present study, we carried out a phylogenomic and comparative genomic analyses to better understand the genetic blueprint of this fungal lineage. We investigated seven Ganoderma genomes, including three new genomes, G. australe, G. leucocontextum, and G. lingzhi. The size of the newly sequenced genomes ranged from 60.34 to 84.27 Mb and they encoded 15,007 to 20,460 genes. A total of 58 species, including 40 white-rot fungi, 11 brown-rot fungi, four ectomycorrhizal fungi, one endophyte fungus, and two pathogens in Basidiomycota, were used for phylogenomic analyses based on 143 single-copy genes. It confirmed that Ganoderma species belong to the core polyporoid clade. Comparing to the other selected species, the genomes of the Ganoderma species encoded a larger set of genes involved in terpene metabolism and coding for secreted proteins (CAZymes, lipases, proteases and SSPs). Of note, G. australe has the largest genome size with no obvious genome wide duplication, but showed transposable elements (TEs) expansion and the largest set of terpene gene clusters, suggesting a high ability to produce terpenoids for medicinal treatment. G. australe also encoded the largest set of proteins containing domains for cytochrome P450s, heterokaryon incompatibility and major facilitator families. Besides, the size of G. australe secretome is the largest, including CAZymes (AA9, GH18, A01A), proteases G01, and lipases GGGX, which may enhance the catabolism of cell wall carbohydrates, proteins, and fats during hosts colonization. The current genomic resource will be used to develop further biotechnology and medicinal applications, together with ecological studies of the Ganoderma species.

Closed Reduction for the Treatment of Grade IV Supination-External Rotation Fracture of the Ankle Joint: A Retrospective Analysis.

OBJECTIVE: To investigate the curative effect of closed reduction and external fixation in the treatment of grade IV supination-external rotation fractures of the ankle joint. METHODS: Fifty-six patients treated with closed reduction and external fixation from February 2016 to March 2020 were included in this retrospective study, all with sprains. After receiving nerve block anesthesia, the patient underwent closed reduction under C-arm fluoroscopy, and the ankle joint was fixed in a dorsiflexion-inversion position with casting and splints after the end of the fracture met the reduction standard by fluoroscopy. One week and four weeks after the reduction treatment, oblique axial and coronal MR scans of the ankle joint were performed to determine the degree of injury and healing of the inferior tibiofibular syndesmosis; anteroposterior and lateral X-rays of the ankle joint (including the ankle acupoints) were regularly reviewed to observe the fracture alignment and healing. Combined with the images and physical examination, the patients were instructed to undergo ankle weight-bearing rehabilitation training when they met the clinical healing standard, and at the last follow-up, the Mazur ankle evaluation and grading system were used for evaluation. After the reduction, the images were evaluated according to the Leeds standard. The image healing of fracture was evaluated by callus growth criteria. RESULTS: The follow-up period of patients ranged from 11 to 58 months, with an average of 26.8 months. The clinical healing time was (8.51 ± 2.12) weeks. The excellent and good rating after reduction was 82.1%, and the excellent and good rating during clinical fracture healing was 73.2%, according to the Leeds imaging evaluation. According to the Mazur ankle evaluation and grading system, the excellent and good rating was 75.0%. Pairwise comparison of callus images at 4, 6 and 12 weeks showed statistically significant differences (P < 0.05), suggesting callus growth at different time periods. A total of 56 patients had anterior inferior tibial fibular ligament (AITFL) injuries (grade II-III), among which 11 patients had AITFL injuries combined with grade II injuries of the interosseous ligament (IOL) and 4 patients had AITFL injuries combined with grade III injuries of the IOL. CONCLUSIONS: Most of the patients with grade IV supination-external rotation fracture of the ankle joint had good prognosis after closed reduction and plaster combined with splint fixation. For patients with IOL injury who had poor prognosis, open reduction and internal fixation therapy is appropriate.

Effects of enhanced recovery after surgery on robotic radical prostatectomy: a systematic review and meta-analysis.

BACKGROUND: Enhanced recovery after surgery (ERAS) has been shown to be an effective, reliable and practical clinical nursing method to support operations on a range of physiological systems, but its effects on robotic radical prostatectomy (RRP) are still unclear. This study assesses the clinical effects of ERAS in RRP. METHODS: Various databases including PubMed, EMBASE, Web of Science and China National Knowledge were searched for relevant studies, in particular full-text articles comparing ERAS groups and conventional groups for RRP. All included articles were subject to a quality assessment, and the data analysis was conducted with Review Manager (5.3). Forest plots, sensitivity analyses, and bias analyses were also prepared based on the included articles. RESULTS: In total, 8 studies were identified that met the inclusion criteria. The results showed that ERAS groups exhibited significantly reduced time of flatus [mean difference (MD) =-0.58; 95% confidence interval (CI): -0.88, -0.29; P=0.0001], time of catheter removal (MD =-1.65; 95% CI: -2.15, -1.16; P<0.00001), and length of stay (LOS) (MD =-1.49; 95% CI: -2.65, -0.34; P=0.01), and there was no significant difference in terms of postoperative complications between ERAS groups and conventional groups (P=0.07). DISCUSSION: This study provides further evidence that ERAS improves postoperative recovery in patients undergoing RRP through reduced time of first flatus, time of catheter removal and LOS. Given the limited quality and quantity of the articles included in this study, further work is needed to validate these findings.

Morphological and molecular identification of two new Ganoderma species on Casuarina equisetifolia from China.

Ganoderma is a cosmopolitan white rot fungal genus, famous for its medicinal properties. In the present study, two new Ganoderma species were collected from south-eastern China and described on the basis of morphological characters and phylogenetic analyses of sequences of the internal transcribed spacer (ITS) region, the translation elongation factor 1-α gene (EF1-α) and the second subunit of RNA polymerase II (RPB2). Specimens of both species were found on living trees of Casuarina equisetifolia. Ganoderma angustisporumsp. nov. is characterised by its sessile basidiomata and almond-shaped, slightly truncate, narrow basidiospores (9-11.3 × 4-5.2 µm). Ganoderma casuarinicolasp. nov. is characterised by its strongly laccate reddish-brown pileal surface, luminous yellow to yellowish-brown cutis and ellipsoid, truncate basidiospores (9-10.2 × 5-6 µm). The two new species are compared with their related taxa. Phylogenetic analyses confirmed that G. angustisporum and G. casuarinicola are distinct species within Ganoderma.

Three new species of Phylloporia (Hymenochaetales) with dimitic hyphal systems from tropical China.

Three new species of Phylloporia from tropical China are described in this study: P. manglietiae, P. pendula, and P. pseudopectinata. Phylloporia manglietiae is characterized by triquetrous to ungulate basidiomata, with 6-8 pores/mm, a monomitic to dimitic hyphal system, and broadly ellipsoidal basidiospores, 3-3.5 × 2-2.5 µm. Phylloporia pendula has small, imbricate, and pendent basidiomata, with 7-9 pores/mm, a dimitic hyphal system, and broadly ellipsoidal basidiospores, 3.5-4 × 2.5-3 µm. Phylloporia pseudopectinata differs from other species of Phylloporia by its applanate basidiomata, with 8-9 pores/mm, a dimitic hyphal system, and subglobose basidiospores, 3-3.5 × 2-3 µm. Phylogenetic analyses, based on sequences from the D1-D2 domains of the 28S gene and the internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2 = ITS) of the nuc rDNA, support the classification of the three new species in Phylloporia.
