CX3CR1, C3, and C3AR1 were the top 3 hub genes in the module correlated with TAA, and the areas under the curve (AUCs) by receiver operating characteristic (ROC) analysis of all the hub genes exceeded 0.7. Finally, we found that the proportions of infiltrating immune cells in TAA and normal tissues were different, especially in terms of macrophages and natural killer (NK) cells.

Chemotaxis and the complement system were identified as crucial pathways in TAA, and macrophages with interactive immune cells may regulate this pathological process.

The coronavirus disease 2019 (COVID-19) pandemic is the largest global event in recent times, with millions of infected people and hundreds of thousands of deaths worldwide. Colombia has also been affected by the pandemic, including by the cancellation of medically necessary surgical procedures that were categorized as nonessential. The objective of this study was to show the results of the program implemented in two institutions in Bogotá, Colombia, in April 2020 to support the performance of elective essential and nonessential low- and medium-complexity orthopedic surgeries during the mitigation phase of the COVID-19 pandemic, which involved a presurgical clinical protocol without serological or molecular testing.

This was a multicenter, observational, retrospective, descriptive study of a cohort of patients who underwent elective orthopedic surgery at two institutions in the city of Bogota, Colombia, in April 2020. We implemented a preoperative clinical protocol that did not involve serological or mole of these four patients visited an emergency department where RT-PCR tests were performed, and they tested negative for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). No patients died or were hospitalized for symptoms of COVID-19.

Through the implementation of a presurgical clinical protocol consisting of a physical examination; a clinical survey inquiring about signs, symptoms, and epidemiological contact with suspected or confirmed cases; and presurgical isolation but not involving the performance of molecular or serological diagnostic tests, positive results were obtained with regard to the performance of low- and medium-complexity elective orthopedic surgeries in an early stage of the COVID-19 pandemic.

Although unloading of the joint is related to reduction of the local bone mineral density (BMD), little attention had been paid to the relationship between loading asymmetry and side-to-side difference of BMD in patients with bilateral knee osteoarthritis (OA). The aim of the present study was to evaluate and clarify the relationship between gait parameters and bone mineral density in those patients.

A total of 36 knees in eighteen patients (mean age = 73.7 ± 6.3 years, mean body mass index = 26.7 ± 3.8 kg/m

) with bilateral medial knee OA were enrolled in the present study. All subjects performed relaxed standing and level walking at our gait laboratory after informed consent was obtained. First, ground reaction force was calculated on bilateral knees during standing. The knees in each patient were divided into higher and lower force side for the definition of dominant side limb. Second, gait parameters in each subject were obtained. To analyze the factors that affect the weight-bearing distribution in the loading condition in patients with bilateral knee OA.

Based on loading asymmetry in the present study, lower BMD was observed on Lower force side in patients with knee OA. Therefore, it is helpful for orthopedic surgeons to examine side-to-side differences of bone mineral density or extension limitation during standing for evaluation of the loading condition in patients with bilateral knee OA.

Human Cytomegalovirus (HCMV) is the most important viral pathogen in people undergoing bone marrow transplantation (BMT). HCMV detection in the early stages makes is possible to save the patients' lives through immediate and timely treatment. The aim of this study was to investigate the status of HCMV using the real-time PCR method in BMT patients in Kermanshah, west of Iran.

HCMV monitoring was done in 120 patients who underwent BMT, 38 allogeneic cases and 82 autologous cases, using the ELISA serology test before transplantation. The participants were followed up 100 days after transplantation for HCMV detection in blood samples using real-time PCR. Preemptive therapy started with Ganciclovir and Foscarnet when the viral load was > 200 HCMV DNA copies/ml.

Despite preemptive therapy, infection recurred in less than 1 month. HCMV recurred more frequently in patients undergoing allogenic transplation versus those receiving autologous transplantation. Recurrence was seen in 5 patients receiving allogenic transplantation. HCMV recurrence occurred in five patients with allogeneic transplantation. Twelve patients undergoing allogeneic or autologous transplantation (83%) and a virus load of > 1000 copies/ml showed HCMV-related symptoms. Three patients died, two due to HCMV-related pneumonia and the other one due to a fungal infection.

Real-time PCR may be a useful method for quantification and monitoring of HCMV recurrence and may be helpful in choosing more efficient HCMV preemptive treatment in BMT recipients.

Absence of cortical alignment in wedge-shaped and multifragmentary fractures (Fx) results in decreased fixation stability. check details The aim of this study was to compare the outcome using 2.0- vs. 3.5-mm screws for open reduction and internal fixation (ORIF) in dislocated, wedge-shaped or fragmentary midshaft clavicle fractures.

Patients suffering from AO/OTA 15 2.A-C midshaft clavicle fractures were operatively treated between 2008 and 2018. 2.0- or 3.5-mm cortical screws were used to restore anatomic alignment in dislocated, wedge-shaped and fragmentary clavicle fractures. Data of radiologic outcome were collected until fracture consolidation was identified.

80 consecutive patients with a mean age of 44.5 ± 16.3years, who were operatively treated for dislocated midshaft clavicle fractures were enrolled. 40 patients were treated using 2.0-mm and 40 patients using routine 3.5-mm cortical screws, respectively. Time to fracture consolidation was 12.8 ± 7.8months. No mal- or non-unions occurred during routine follow-up until 18months postoperatively.
