For initial recurrent hepatocellular carcinoma (irHCC), there is no consensus regarding the monitoring strategy after ablation. The present study investigated surveillance strategies for irHCC after ablation to support clinical decision making.

Data from irHCC patients who received ablation were retrospectively collected at two medical centers. The risk of tumor relapse in each month was calculated through random survival forest methodology, and follow-up schedules were arranged thereafter to maximize the capability of relapse detection at each visit.

The cumulative 0.5-, 1-, 1.5-, and 2-year risk-adjusted probabilities in the train/validation cohorts were 26.2%/21.5%, 42.3%/39.4%, 55.5%/52.6%, and 61.3%/63.2%, respectively, with the highest recurrence rate occurring in the second month (maximum= 7.9%/7.4%). The surveillance regime primarily concentrated on the first year post treatment, especially the initial six months. The delay in detecting tumor recurrence gradually decreased when the total number of follow-up visits increased from 4 to 8. Compared with the control strategies, this schedule (follow-up visits at 2, 4, 6, 9, 12, and 18 months) reduced the delay in detection. The benefits of this surveillance regime were evident when the patients were followed up six times. The proposed 6-visit surveillance strategy significantly decreased the delay in detection compared with the control 7-visit approach (1.32 versus 1.82 months, P< 0.001).

The proposed new surveillance schedule minimized the delay in detecting recurrence in irHCC patients after ablation. Our risk-related machine learning method could be applied to develop follow-up strategies for other HCC patients.

Due to the importance, anatomy training is worldwide recognizable in virtually all undergraduate curricula and many postgraduate surgical curricula (Estai and Bunt, 2016; Older, 2004). The postgraduate curriculum of Obstetrics and Gynaecology (O&G) is such a surgical curriculum. It is a diverse branch of medicine and the role of anatomy in O&G is versatile. In the Netherlands nor in Europe the expectations of knowledge on anatomy are specified in the current training program, making trainees insecure about their performance in anatomy knowledge ("Better Education for Obsetrics and Gynaecology,"). Therefore, we recently performed a Delphi study to determine which anatomical structures should be taught to ensure safe and competent practice among general gynaecologists (Koppes et al., 2020). The aim of this study is the determination of the anatomical knowledge level in postgraduate training for O&G. Our hypothesis is that the trainees possess a good knowledge of anatomy and on average at least 80%. Our results are a step in the awareness of testing and improving anatomy knowledge of postgraduate O&G training.

Because of the widespread and high reliability of free flaps in head and neck reconstruction, the challenge today is to reduce donor site morbidity. The external pudendal artery (EPA) free flap has been described in men and provides a minimal functional and cosmetic impact. This study aimed to assess the feasibility of the EPA free flap in women for buccopharyngeal reconstruction.

A dissection of the inguinal region was performed bilaterally on fresh female cadavers. The anatomy of the EPA and its angiosome were described, along with the design of the EPA free flap. A computed tomography angiographic study of the flap perfusion was performed.

Fourteen cadavers were dissected. The EPA was constant. Its diameter ranged from 1.12 to 2.96mm (median 2.0mm). The mean area of its angiosome was 167.3±38.5cm

. An axial fasciocutaneous flap was designed with a horizontal skin paddle measuring on average 9.2×6cm and a pedicle length of 8.4±1.9cm. The mean flap thickness was 11.7±6.8mm and depended on individual factors. A primary closure was achieved in all cases with a scar hidden in the underwear.

This anatomical study demonstrates that the EPA seems constant despite variations in its origin pattern. Its diameter and angiosome allow the design of an EPA free flap in women. A clinical study should confirm that this flap is suitable for the repair of buccopharyngeal defects and could be added to the armamentarium of the head and neck reconstructive surgeon.

It is most closely related to E. hirae, E. durans, E. villorium, and E. mundtii with 100%, 91,55%, 90,85%, and 90,58% homology, respectively, but more distant from SodA of E. faecalis (81.68%). A sodA deletion mutant has been constructed. Compared to the parental strain, the ΔsodA mutant was affected in aerobic growth and more sensitive to hydrogen peroxide (H2O2), cumene hydroperoxide (CuOOH), and the superoxide anion (O2•-) generator menadione. The E. faecium strain AUS0004 is part of those bacteria accumulating H2O2 to high concentrations (around 5 mM) starting from late exponential growth phase. Accumulation of the peroxide was around 25 % less in the mutant suggesting that this part of H2O2 is due to the dismutation of O2•- by SodA. The sodA gene of E. faecium AUS0004 was induced by oxygen, peroxides and menadione but the corresponding regulator remains hitherto unknown. Finally, we showed that SodA activity is important for virulence in the Galleria mellonella model.

We sought to evaluate safety of electrical cardioversion (ECV) for patients with acute atrial fibrillation (AF) or atrial flutter (AFL) in the emergency department (ED).

This was an analysis of data from four multicentre AF/AFL studies conducted between 2008 and 2019 at 23 large EDs. We included adult patients who received attempts at ECV and who had presented acutely after symptom onset. Staff manually reviewed study and clinical records to abstract data.

We evaluated 1,736 ECV cases with mean age 60.1 years and male 67.1%. The overall success of ECV was 90.2% (95% CI 88.7-91.6%) with 4.9% of patients admitted. ED physicians performed the ECV in 95.2% and provided sedation in 96.5%. 13.9% (12.3-15.7%) of cases experienced important adverse events that required treatment and 0.4% were classified life-threatening. Another 5.6% had adverse events that did not require treatment. Logistic regression found that the RAFF3 study cohort (OR 2.0), age ≥85 years (OR 2.1), coronary artery disease (OR 1.5), midazolsions with patients when choosing between drug-shock and shock-only cardioversion strategies.

Chronic hepatitis C virus (HCV) infection affects the immune system. Whether elimination of HCV with direct-acting antivirals (DAA) restores immunity is unclear. We used mass cytometry to get a broad and in-depth assessment of blood cell populations of patients with chronic HCV prior to and after DAA therapy.

Before and 12weeks after sustained virological response to DAA therapy (SVR12), 22 cell populations were analysed by mass cytometry in blood collected from 10 healthy controls and 20 HCV patients with (10) or without human immunodeficiency virus (HIV) (10) infection.

HCV infection altered the frequency of 14/22 (64%) blood cell populations. At baseline, the frequencies (median [IQR]; control, HCV, HCV/HIV) of intermediate monocytes (1.2 [0.47-1.46], 1.76 [0.83-2.66], 0.78 [0.28-1.77]), non-classical monocytes (1.11 [0.49-1.26], 0.9 [0.18-0.99], 0.54 [0.28-1.77]), conventional dendritic cells type 2 (0.55 [0.35-0.59], 0.31 [0.16-0.38], 0.19 [0.11-0.36]) and CD56

natural killer cells (8.08 [5.34-9.79], 4.72 [2.59-6.05], 3.61 [2.98-5.07]) were reduced by 35% to 65%, particularly in HCV/HIV co-infected patients. In contrast, activated double-negative T cells (0.07 [0.06-0.10], 0.10 [0.09-0.19], 0.19 [0.12-0.25]), activated CD4 T cells (0.28 [0.21-0.36], 0.56 [0.33-0.77], 0.40 [0.22-0.53]) and activated CD8 T cells (0.23 [0.14-0.42], 0.74 [0.30-1.65], 0.80 [0.58-1.16]) were increased 1.4 to 3.5 times. Upon stimulation with Toll-like receptor ligands, the expression of cytokines was up-regulated in 7/9 (78%) and 17/19 (89%) of the conditions in HCV and HCV/HIV patients, respectively. Most alterations persisted at SVR12.

The mechanism of carcinogenesis in glioma remains largely unclear. In the present study, we identified a dysregulated long non-coding RNA (lncRNA) solute carrier family 8 member A1 antisense RNA 1 (SLC8A1-AS1) associated with glioma based on The Cancer Genome Atlas (TCGA) data. A validation experiment was conducted to confirm a high expression level of lncRNA SLC8A1-AS1 in glioma tissues. Down-regulation of lncRNA SLC8A1-AS1 suppressed the proliferation, colony formation, migration, and invasion of glioma cells in vitro and in vivo. Moreover, lncRNA SLC8A1-AS1 silencing decreased the activity of the Wnt/β-catenin pathway and suppressed the epithelial to mesenchymal transition (EMT) in glioma cells. These findings collectively provide novel insights into the function and mechanism of lncRNA SLC8A1-AS1 in the pathogenesis of glioma and highlight its potential as a therapeutic target for glioma intervention.

Efavirenz is a vital component used to treat HIV-1 infection. Nevertheless, it shows large between-subject variability, which affects both its therapeutic response and adverse effects.

To investigate the impact of gene polymorphisms and non-genetic factors on the variability of efavirenz pharmacokinetics and to propose the optimal dose regimens.

A total of 769 plasma samples from 376 HIV-infected Han Chinese outpatients were collected to develop a population pharmacokinetic model using NONMEM software. The impact of patient demographics, laboratory tests, concomitant medication, and genetic polymorphisms of CYP2B6 and ABCB1 on efavirenz pharmacokinetics were explored. According to the final model, the model-informed dose optimization was conducted.

The pharmacokinetics of efavirenz was characterized by a one-compartment model with first-order absorption and elimination. The typical values of the estimated apparent oral clearance, volume of distribution, and absorption rate constant in the final model were 9.44L/h, 200L, and 0.727 h



, respectively. Efavirenz clearance was significantly influenced by CYP2B6 variants, including rs2099361, rs3745274, and rs2279343, along with albumin and weight. Proteasome inhibitor The volume of distribution was affected by albumin and weight. Based on the CYP2B6 polymorphisms of patients, the recommended daily doses of efavirenz were 100mg for CYP2B6 slow metabolizers, 400 or 600mg for intermediate metabolizers, and 800 or 1000mg for extensive metabolizers.

Polymorphisms of CYP2B6, along with albumin and weight, resulted as the predictors of efavirenz pharmacokinetic variability, which could be used in prescribing optimal efavirenz doses.
