960 and 0.566, respectively). In addition, there were no significant differences in treatment-related adverse events among these three age groups, except for proteinuria of any grade. In a subgroup analysis of patients treated with Atez/Bev as first-line systemic therapy, there were no significant differences in cumulative overall or progression-free survival between the elderly and non-elderly groups (p=0.728 and 0.805, respectively).

Atez/Bev can be used efficaciously and safely in spite of age in patients with unresectable HCC.

This hydrogel has the affinity and digestive capacity for a fuel α-poly-L-lysine by incorporating acrylic acid and trypsin. The hydrogel captured fuel and transiently shrank owing to the construction of electrostatic cross-linkages. This process was inherently connected with the digestion of these cross-linkages and the release of oligo-lysine as waste, which induced the reswelling of the hydrogel at equilibrium. The transient volume change of the hydrogel realized the fuel-stimulated transient release of a payload. This study provides a strategy for engineering materials with biomacromolecule-fueled dynamic functions under the out-of-equilibrium condition.

To evaluate the outcomes of Ilizarov ankle arthrodesis in the treatment of end-stage varus ankle osteoarthritis (OA).

This was a retrospective study of 63 patients with varus ankle OA who underwent Ilizarov ankle arthrodesis between June 2013 and December 2018. There were 24 males and 39 females with an average age of 56.57 ± 4.45 years (range, 47-64 years). Thirty-six cases were affected on the left side, and 27 were affected on the right side. The patients' mean body mass index (BMI) was 25.18 ± 2.93 kg/m

. According to the modified Takakura staging criteria, there were 18 cases of stage 3b (28.57%) and 45 cases of stage 4 (71.43%). Nine patients were primary (14.29%), 48 were traumatic (76.19%), and six were caused by rheumatoid OA (9.52%). Functional assessments were performed according to the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Ankle Osteoarthritis Scale (AOS), and visual analogue scale (VAS). The tibial anterior surface angle (TAS), coronal plane tibial-talar aients developed superficial pin tract infections, all settled with local dressing and antibiotic treatment. Two patients were found to have subtalar arthritis and underwent conservative treatment.

Ankle arthrodesis using the Ilizarov technique is efficient in treating end-stage varus ankle OA.

Home hemodialysis (HHD) remains underused in patients with kidney failure. Current literature on HHD mostly originates from non-European countries, making generalization difficult. The present study describes patients' profile and practice patterns from a Belgian HHD center, and assesses patient and technique survival and complications associated with HHD.

We analyzed data from all our incident patients during a 6-year period. The patient's characteristics were summarized using descriptive statistics. Transition to another therapeutic modality, estimated using a risk model with death and transplantation as competing events, episodes of respite cares and hospitalizations, and access complications were analyzed.

Eighty patients (mean age 47 years; male 64%) met the inclusion criteria. Fifty-one percent of patients initiated dialysis with a central venous catheter (CVC) and 96% were not assisted. Arterio-venous fistula (AVF) cannulation was performed using buttonhole technique. Standard-frequent HD (47%) and short-frequent low-flow dialysate HD (34%) were mostly used at HHD initiation. Cumulative incidences of technique failure and death were 15%, 24%, and 32% at 1, 2, and 5 years. Incidence rates for respite dialysis and hospitalizations were 2.39 and 0.54 per patient-year of HHD. In comparison with AVF, incidence rate ratios of overall access complications and access-related infections for CVC were 4.3 (95% CI 3.1-6, p< 0.01) and 4.4 (95% CI 2.1-10, p< 0.01), respectively. Buttonhole cannulation was complicated by 0.26 (95% CI 0.15-0.46) infections per 1000 AVF-days.

This present study provides important information about patient's profile and practice patterns and safety in a cohort of 80 incident Belgian HHD patients, with encouraging techniques and patient survival.

However, encephalopathy is an emerging adverse effect of ceftriaxone infusion. These patients present with various symptoms, including those of neurotoxicity, that typically resolve 1 week after discontinuation of ceftriaxone. We experienced two cases of ceftriaxone-induced encephalopathy that were successfully treated by rapid removal of ceftriaxone by hemoperfusion.

Necrotizing enterocolitis (NEC) is a catastrophic gastrointestinal emergency in preterm infants, whose exact aetiology remains unknown. The role of lithocholic acid (LCA), a key component of secondary bile acids (BAs), in NEC is unclear.

Clinical data were collected to analyse the changes of BAs in NEC patients. In vitro studies, the cell proliferation and cell death were assessed. In vivo experiments, the newborn rats were administered with low or high dose of LCA and further induced NEC.

Clinically, compared with control group, total BAs in the NEC patients were significantly higher when NEC occurred. In vitro, LCA treatment significantly inhibited the cell proliferation through arresting cell cycle at G1/S phase without inducing apoptosis or necroptosis. Mechanistically, the Wnt/β-catenin pathway was involved. In vivo, LCA inhibited intestinal cell proliferation leading to disruption of intestinal barrier, and thereby increased the severity of NEC. Specifically, LCA supplementation caused higher levels of FITC-labelled dextran in serum, reduced PCNA expression and inhibited the activity of Wnt/β-catenin pathway in enterocytes. The LC-MS/MS test found that LCA was significantly higher in intestinal tissue of NEC group, and more obviously in the NEC-L and NEC-H group compared with the DM group.

LCA exacerbates NEC by inhibiting intestinal cell proliferation through downregulating the Wnt/β-catenin pathway.

To explore changes in body weight and cardiometabolic risk factors after treatment withdrawal in the STEP 1 trial extension.

STEP 1 (NCT03548935) randomized 1961 adults with a body mass index ≥ 30 kg/m

(or ≥ 27 kg/m

with ≥ 1 weight-related co-morbidity) without diabetes to 68 weeks of once-weekly subcutaneous semaglutide 2.4mg (including 16 weeks of dose escalation) or placebo, as an adjunct to lifestyle intervention. At week 68, treatments (including lifestyle intervention) were discontinued. An off-treatment extension assessed for a further year a representative subset of participants who had completed 68 weeks of treatment. This subset comprised all eligible participants from any site in Canada, Germany and the UK, and sites in the United States and Japan with the highest main phase recruitment. All analyses in the extension were exploratory.

Extension analyses included 327 participants. From week 0 to week 68, mean weight loss was 17.3% (SD 9.3%) with semaglutide and 2.0% (SD 6.1%) with placebo.g treatment is required to maintain improvements in weight and health.Acellular skin as a scaffold has a good potential to regenerate or repair damaged tissues. Growth factors such as Plasma Rich in Growth Factor (PRGF) as a rich source of active proteins can accelerate tissue regeneration. In this study, an acellular scaffold derived from fish skin with growth factors was used to repair full-thickness skin defects in a rat model. Cellular results demonstrated that epithelial cells adhere well to acellular scaffolds. The results of animal studies showed that the groups treated with acellular scaffold and growth factor have a high ability to close and heal wounds on the 28th day after surgery. Histological and staining results showed that in the treated groups with scaffold and growth factor, an epidermal layer was formed with some skin appendages similar to normal skin. Overall, such scaffolds with biological agents can cause an acceptable synergistic effect on skin regeneration and wound healing.

HIV reservoirs and infected cells may persist in tissues with low concentrations of antiretrovirals (ARVs). Traditional pharmacology methods cannot assess variability in ARV concentrations within morphologically complex tissues, such as lymph nodes (LNs). We evaluated the distribution of six ARVs into LNs and the proximity of these ARVs to CD4

T cells and cell-associated RT-SHIV viral RNA.

Between December 2014 and April 2017, RT-SHIV infected (SHIV+; N = 6) and healthy (SHIV-; N = 6) male rhesus macaques received two selected four-drug combinations of six ARVs over 10 days to attain steady-state conditions. Serial cryosections of axillary LN were analysed by a multimodal imaging approach that combined mass spectrometry imaging (MSI) for ARV disposition, RNAscope in situ hybridization for viral RNA (vRNA) and immunohistochemistry for CD4

T cell and collagen expression. Spatial relationships across these four imaging domains were investigated by nearest neighbour search on co-registered images using MAt one drug at concentrations greater than the IC50 value.

Our investigation of the spatial distributions of drug, virus and target cells underscores the influence of location and microenvironment within LN, where a small population of T cells may remain vulnerable to infection and low-level viral replication during suppressive ART.

To compare the pharmacokinetic (PK) and pharmacodynamic (PD) effects and safety of therapeutic dosages of a regular insulin (experimental drug) produced by Bioton S.A. (Warsaw, Poland) versus Humulin® R, a regular insulin (reference drug) produced by Eli Lilly (Indianapolis, Indiana).

In a single-centre, randomized, double-blinded phase 1 crossover study, we used the manual euglycaemic clamp technique to compare PK and PD profiles between single subcutaneous doses (0.3units/kg) of the two regular insulins in participants with type 1 diabetes (T1DM) with a washout period of 14 (± 7) days between tests.

We evaluated 56 participants. The mean participant age and body mass index were 32.9 years and 22.9kg/m

, respectively. The ratios (experimental/reference) of the geometric means of maximum plasma insulin concentration and for plasma insulin area under the curve (AUC) were 0.909 (90% confidence interval [CI] 0.822-1.01) and 0.993 (90% CI 0.944-1.04), respectively. The ratios of the geometric means of maximum glucose infusion rate (GIR) and for GIR AUC were 0.
