Background and Objectives: Chronic venous disease (CVD) is a widespread clinical condition that is very common in western countries in the adult general population with a wide range of clinical manifestations, such as varicose veins (VVs) that in certain circumstances may complicate with rupture and subsequent bleeding that may even be fatal. The aim of this study is to evaluate risk factors for bleeding VVs. Materials and Methods: This is a retrospective study conducted in patients with CVD complicating with bleeding of VVs over a 4-year period (2019-2022). ⋯ A group of 99 patients without VVs bleeding were randomly selected from the total population of 1048 patients with CVD. Findings of this study showed that advanced clinical stage of CVD (i.e., C4b stage), advanced age, living alone, suffering from cardiovascular co-morbidity (i.e., hypertension and CHF), assuming certain drugs that act on blood coagulation (i.e., aspirin, anticoagulants), assuming psychotropic medication, having particular venous reflux patterns (i.e., below-knee GSV reflux, non-saphenous veins reflux, Cockett's perforators reflux), and not having been assessed and treated previously for CVD (i.e., with VADs, CT, or surgery) may predispose a high risk for bleeding VVs. Conclusions: Bleeding VVs may be a life-threatening complications of CVD patients, and monitoring risk factors found in this study and others that, hopefully, may be discovered in the future through further focused research will help to reduce the impact of this problem in this patient population.

Background and Objectives:: There were limited studies which investigated nail diameter as a predictor for cephalomedullary nail (CMN) failure in intertrochanteric fracture (ITF). We aimed to evaluate the surgical outcomes of CMN in fragility ITF following nail-canal (N-C) diameter discordance. Materials and Methods: From November 2010 to March 2022, we retrospectively reviewed 120 consecutive patients who underwent CMN surgeries due to fragility ITF. ⋯ For analyses in the lateral view, the lat-concordance and lat-discordance groups had 8 (27%) and 20 patients (22%) with a sliding distance of >5 mm (p = 0.62), while treatment failure occurred in 1 (3%) and 4 (4%) patients, respectively (p = 1.00). Linear regression analyses showed that the N-C difference in either views was not a significant predictor of sliding distance in both the AP (R2 = 0.002, p = 0.60) and lateral views (R2 = 0.007, p = 0.35). Conclusions: If appropriate fracture reduction and fixation are achieved, the N-C discordance of short CMN does not affect treatment outcomes in ITF.

Review Meta Analysis
Remdesivir Treatment Lacks the Effect on Mortality Reduction in Hospitalized Adult COVID-19 Patients Who Required High-Flow Supplemental Oxygen or Invasive Mechanical Ventilation.
Background and Objectives: The therapeutic impact of remdesivir on hospitalized adult COVID-19 patients is unknown. The purpose of this meta-analysis was to compare the mortality outcomes of hospitalized adult COVID-19 patients receiving remdesivir therapy to those of patients receiving a placebo based on their oxygen requirements. Materials and Methods: The clinical status of the patients was assessed at the start of treatment using an ordinal scale. ⋯ Hospitalized adult COVID-19 patients who did not require supplemental oxygen or who required low-flow oxygen and were treated with remdesivir had a lower mortality risk. In contrast, hospitalized adult patients who required high-flow supplemental oxygen or invasive mechanical ventilation did not have a therapeutic benefit in terms of mortality. Conclusions: The clinical benefit of mortality reduction in hospitalized adult COVID-19 patients treated with remdesivir was associated with no need for supplemental oxygen or requiring supplemental low-flow oxygen at the start of treatment, especially in those requiring supplemental low-flow oxygen.

Background and Objectives: Methotrexate (MTX) is routinely prescribed for rheumatoid arthritis (RA) patients, but high cumulative doses may lead to hepatic fibrosis. Additionally, a high proportion of RA patients suffer from metabolic syndrome, which also increases the risk of hepatic fibrosis. This cross-sectional study aimed to explore the association between a cumulative MTX dose, metabolic syndrome, and hepatic fibrosis in patients diagnosed with RA. ⋯ After multivariate analysis, only BMI (OR = 14.73; 95% CI 2.90-74.79; p = 0.001), insulin resistance (OR = 312.07; 95% CI 6.19-15732.13; p = 0.04), and cumulative MTX dosage (OR 1.03; 95% CI 1.01-1.10; p = 0.002) were associated with hepatic fibrosis. Conclusions: While the cumulative MTX dose and metabolic syndrome are both the risk factors of hepatic fibrosis, metabolic syndrome, including a high BMI and insulin resistance, poses a greater risk. Therefore, MTX-prescribed RA patients with metabolic syndrome factors should be attentively monitored for signs of liver fibrosis.

Background and Objectives: The aim of this study is to investigate the femoral tunnel geometry (femoral tunsnel location, femoral graft bending angle, and femoral tunnel length) on three-dimensional (3D) computed tomography (CT) and graft inclination on magnetic resonance imaging (MRI) after anatomic anterior cruciate ligament (ACL) reconstruction using a flexible reamer system. Materials and Methods: A total of 60 patients who underwent anatomical ACL reconstruction (ACLR) using a flexible reamer system were retrospectively reviewed. One day after the ACLR procedure was performed, all patients underwent three-dimensional computed tomography (3D-CT) and magnetic resonance imaging (MRI). ⋯ The results of this study demonstrated that a comparable femoral graft bending angle and longer femoral tunnel length were observed compared with the reported outcomes from previous studies that used the rigid reamer system. Conclusions: ACLR using a flexible reamer system allowed for an anatomic femoral tunnel location and a comparable graft inclination to that of the native ACL. In addition, it achieved a tolerable femoral graft bending angle and femoral tunnel length.
