Our investigation documents the isolation and identification of monkeypox virus from humans in the Western Hemisphere. Infection of humans was associated with direct contact with ill prairie dogs that were being kept or sold as pets.
While 6% of patients had MDIS, only 1% had MDAS. MDIS was associated with both anxiety and depression; patients with both anxiety and depression had an almost twofold increased odds of MDIS. MDAS was associated with a 40% increased odds of depression, but there was no significant association with anxiety. Psychological assessments may be useful in the evaluation and treatment of patients with MDIS and MDAS; physiologic causes for MDAS warrant further investigation.
Herba Epimedii (HEP) known as YinYangHuo in Chinese is the dried leaf of the Epimediium, and has been historically used in combination with other herbs to treat skeletal diseases in traditional Chinese medicine (TCM). Here, we review the historical TCM interpretation of the action of HEP, its use in clinical trials, its main phytochemical constituents and its pharmacological findings. 85 clinical trials were identified which used HEP in TCM prescriptions with other herbs to treat primary and secondary osteoporosis from 2005 to now. More than 60 individual compounds were isolated and characterized from HEP and studied in various animal and cell models. HEP and its constituents exhibited a variety of anti-resorptive and bone formation-stimulating effects, which target different pathways in the bone remodeling cycle. These compounds may provide new perspectives in alternative treatment regimes and reveal novel chemical scaffolds for the development of anti-osteoporotic drugs. These approaches are also useful for guiding our research to employ an integrative therapeutic approach to treat complex diseases such as osteoporosis diseases which could be superior to the conventional single target - single drug approach.
Purpose: Increasing evidence supported that semaphorin 3A (Sema3A), insulin-like growth factor (IGF)-1 and β-catenin were involved in the development of osteoporosis and diabetes. This study is aimed to evaluate whether Sema3A/IGF-1/β-catenin is directly involved in the alterations of bone microarchitecture and bone strength of diabetic rats. Methods: Diabetic rats were induced by streptozotocin and high fat diet exposure. Bone microarchitecture and strength in the femurs were evaluated by micro-CT scanning, three-point bending examination and the stainings of HE, alizarin red S and safranin O/fast green, respectively. The alterations of lumbar spines microarchitecture were also determined by micro-CT scanning. Western blot and immunohistochemical analyses were used to examine the expression of Sema3A, β-catenin, IGF-1, peroxisome proliferator-activated receptor γ (PPARγ) and cathepsin K in rat tibias. Results: Diabetic rats exhibited decreased trabecular numbers and bone formation, but an increased trabecular separation in the femurs and lumbar spines. Moreover, the increased bone fragility and decreased bone stiffness were evident in the femurs of diabetic rats. Diabetic rats also exhibited a pronounced bone phenotype which manifested by decreased expression of Sema3A, IGF-1 and β-catenin, as well as increased expression of cathepsin K and PPARγ. Conclusions: This study suggests that diabetes could perturb bone loss through the Sema3A/IGF-1/β-catenin pathway. Sema3A deficiency in bone may contribute to upregulation of PPARγ and cathepsin K expression, which further disrupts bone remodeling in diabetic rats.
ObjectiveThe aim of this study was to compare clinical outcomes of patients with femoral neck fractures treated with the dynamic hip system blade (DHS-BLADE) or cannulated compression screws.MethodsEighty-six patients with femoral neck fractures were treated by closed reduction internal fixation with a DHS-BLADE (n = 42; 18 males and 24 females; mean age: 56.3 years (37–87)) or cannulated compression screws (n = 44; 20 males and 24 females; mean age: 53.8 years (26–83)) between March 2011 and August 2013. The groups were compared with Harris hip score, operation time, surgical blood loss, incision size, hospital stay, and related complications.ResultsThe average follow-up time was 27 months (range, 24–36 months). There was no significant difference for the operation time, incision size, hospital stay, and Harris hip score between the groups. Also, no statistically significant differences in the rates of nonunion (4.5% vs. 0) and avascular necrosis of the femoral head (9.1% vs. 7.1%) were observed. However, the screw group experienced significantly less surgical blood loss (32.4 ± 24.7 ml) than the blade group (87.2 ± 46.6 ml; P = 0.041). The incidence of femoral neck shortening above 10 mm in the screw group was significantly higher than that in the blade group (15.9% vs. 2.4%, P = 0.031). The blade group had a significantly lower incidence of screw migration than the screw group (4.8% vs. 22.7%, P = 0.016).ConclusionThe DHS-BLADE and cannulated compression screws might be equally effective in terms of postoperative fracture union. However, the DHS-BLADE has advantages over cannulated compression screws for preventing femoral neck shortening, screw migration, and cut-out.Level of evidenceLevel III, Therapeutic study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
