Reorganization of the extracellular matrix is a prerequisite for healthy adipose tissue expansion, whereas fibrosis is a key feature of adipose dysfunction and inflammation. However, very little is known about the direct effects of impaired cell-matrix interaction in adipocyte function and insulin sensitivity. The objective of this study was to determine whether integrin activity can regulate insulin sensitivity in adipocytes and thereby systemic metabolism.

We characterized integrin activity in adipose tissue and its consequences on whole-body metabolism using adipose-selective deletion of β1 integrin (Itgb1

) and Kindlin-2 (Kind2

) in mice.

We demonstrate that integrin signaling regulates white adipocyte insulin action and systemic metabolism. Consequently, loss of adipose integrin activity, similar to loss of adipose insulin receptors, results in a lipodystrophy-like phenotype and systemic insulin resistance. However, brown adipose tissue of Kind2

and Itgb1

mice is chronically hyperactivated and has increased substrate delivery, reduced endothelial basement membrane thickness, and increased endothelial vesicular transport.

Thus, we establish integrin-extracellular matrix interactions as key regulators of white and brown adipose tissue function and whole-body metabolism.

Definitive treatment techniques for symptomatic deep venous reflux have been relegated to complex and invasive open surgery which is rarely performed today. The BlueLeaf System provides an endovenous method for the formation of deep venous valves without an implant, avoiding the complications associated with permanent foreign materials. The system has the adaptability to form valves within the femoral and popliteal veins at multiple levels in a single procedure. The aim was to determine the midterm safety and efficacy of this novel device in an early feasibility study.

Feasibility of endovenous deep venous valve formation was assessed in patients with chronic venous insufficiency (Clinical, Etiologic, Anatomic, Pathophysiologic [CEAP] 4-6). Follow-up was completed through 1year, assessing vein patency and reflux time (RT) with duplex ultrasound examination. Venous clinical improvement was evaluated using the revised Venous Clinical Severity Scale.

Of the 14 patients, 13 (93%) had successful formation offive patients with a total of nine active ulcers at baseline had four active ulcers at 360days.

The BlueLeaf System holds promise as a minimally invasive means to safely form fully autogenous deep venous valves. Reconstructed deep veins remained patent, without deep venous thrombosis and symptomatic improvement was consistently observed; however, a decrease in the RT was not. Incremental device design improvements have been undertaken to improve valve function. The results of these iterations await further clinical evaluation.

Pharmacomechanical catheter-directed thrombolysis (PCDT) is rarely reported in treating bilateral lower extremity deep venous thrombosis (LEDVT). This study was aimed to investigate the safety, patency, and mid-term outcomes of the Aspirex®S thrombectomy system combined with catheter-directed thrombolysis (CDT) in treating symptomatic bilateral LEDVT.

The clinical data of 45 consecutive patients with acute or subacute bilateral LEDVT (60.00% male; mean age, 53.8± 16.5years) who received endovascular treatment with PCDT between January 2015 and June 2019 were retrospectively analyzed in this study. The clinical efficacy of thrombolysis (≥50% thrombolysis), complications, primary patency, valvular function, and cumulative prevalence of post-thrombotic syndrome (PTS) were retrospectively analyzed.

PCDT was performed in all 45 patients successfully. No serious procedure-related complication or death was observed. The average urokinase dosage was 4.1± 1.5 million IU, and the average thrombolysis time was 5.3± 1.3days. The mean length of hospital stay was 9.9± 2.5days. The primary patency was 100% after lysis. The clinical efficacy of thrombolysis was 86.7% (39/45). Deep venous thrombosis recurrence was observed in six (13.3%) patients within 12months after discharge. The primary patency at 1-, 3-, 6-, 9-, and 12-month follow-up was 97.8%, 93.3%, 88.9%, 82.2%, and 73.3%, respectively. The cumulative prevalence of PTS was 24.4% (11/45) throughout the follow-up period, whereas the prevalence of moderate and severe PTS was only 6.7% (3/45).

PCDT for treating bilateral LEDVT is feasible, effective, and safe.

We aim to determine the effect of a fixed-dose combination (FDC) of tiotropium/olodaterol on Physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) in a real world setting.

COPD patients were prospectively enrolled to evaluate the effect of a FDC of tiotropium/olodaterol inhaler therapy via the Respimat® Soft Mist™ inhaler (SMI) on the physical functioning scale (PF-10), and the general condition of the patient as assessed by the physician (Physician's Global Evaluation, PGE), and the patient's satisfaction after 6 weeks of treatment. The primary end-point was the percentage of patients with therapeutic success at 6th week follow-up, defined as a ≥10-points increase in the standardised PF-10 score from baseline.

A total of 257 patients from 57 sites were enrolled, and 234 completed the follow up. After 6 weeks of treatment, 155 out of 234 patients (66.2%) showed therapeutic success in the physical functioning score, coupled with significant improvement in PGE score 78 (33.3%) patients with good/excellent PGE score at baseline, increasing to 172 (73.
