There were investigated 22 patients with chronic obstructive pulmonary disease in association with arterial hypertension initially and after 5 weeks of treatment with beta-blocker Nebivolol 5 mg/day. There were not detected any negative changes on bronchial permeability after treatment. Considerable improvement of endothelial function (from 7-12% to 17-35%, p < 0.05) in parallel with decreasing of pulmonary artery, systolic (44.5 +/- 5.5 mmHg vs. 32.8 +/- 4.1 mmHg, p < 0.05) and mean pressure (26.3 +/- 4.2 mmHg vs. 21.1 +/- 2.1 mmHg, p < 0.05)--were observed after treatment. Thus, Nebilet is well-tolerated and highly effective in patients with chronic obstructive pulmonary disease in association with arterial hypertension.

Lateral decubitus: its influence on hemodynamic and respiratory function during retroperitoneal robotic assisted laparoscopic pyeloplasty (R-RALP) in children.

J Robot Surg

January 2025

Department of Pediatric Anesthesia and Intensive Care, Necker-Enfants Malades University Hospital, AP-HP Centre, Université Paris Cité, 149, Rue de Sèvres 75015, Paris, France.

Retroperitoneal robotic-assisted laparoscopic pyeloplasty (R-RALP) is the commonest urologic procedure performed in children, entailing retroperitoneal CO2 insufflation and lateral decubitus, whose effects on cardiopulmonary variables are poorly known. We, therefore, studied hemodynamic and respiratory changes due to CO2 insufflation and lateral decubitus in children undergoing R-RALP and their effects on regional tissue oxygenation. Between 1/2021 and 7/2024, children affected by ureteropelvic joint obstruction (UPJO) underwent a pyeloplasty by R-RALP at Necker Enfants Malades Hospital (Paris, France), using a standardized surgical technique and a lung-protecting anesthetic protocol aimed to prevent hypercarbia.

Ciliary muscle traction during accommodation is able to induce optic nerve head deformation.

Eye (Lond)

January 2025

Key Laboratory for Biomechanics and Mechanobiology of Ministry of Education, Beijing Advanced Innovation Center for Biomedical Engineering, Beihang University, Beijing, China.

Objectives: To use finite element (FE) modeling and in vivo optical coherence tomography (OCT) imaging to explore the effect of ciliary muscle traction on optic nerve head (ONH) deformation during accommodation.

Methods: We developed a FE model to mimic the ciliary muscle traction during accommodation, and varied the stiffness of the sclera, choroid, Bruch's membrane (BM), prelaminar neural tissue and lamina cribrosa (LC) to assess their effects on accommodation-induced ONH strains. To validate the FE model, OCT images of the right eyes' ONHs from 20 subjects (25 ± 1.

Background: Although surviving sepsis campaign (SSC) guidelines are the standard for sepsis and septic shock management, outcomes are still unfavourable. Given that perfusion pressure in sepsis is heterogeneous among patients and within the same patient; we evaluated the impact of individualized hemodynamic management via the transcranial Doppler (TCD) pulsatility index (PI) on mortality and outcomes among sepsis-induced encephalopathy (SIE) patients.

Methods: In this prospective, single-center randomized controlled study, 112 patients with SIE were randomly assigned.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2is) reportedly decreased the new-onset atrial arrhythmias in patients with type-2 diabetes (T2DM) or heart failure (HF). This study examined the impact of SGLT2is on catheter ablation for atrial fibrillation (AF) in HF patients without T2DM.

Methods: Persistent AF (PeAF) and HF (N-terminal prohormone of brain natriuretic peptide, NT-proBNP ≥400 pg/ml) patients without T2DM undergoing catheter ablation were prospectively enrolled (n = 102).

Intraoperative FiO and risk of impaired postoperative oxygenation in lung resection: A propensity score-weighted analysis.

J Clin Anesth

January 2025

Department of Anesthesia, Critical Care and Pain Medicine, Massachusetts General Hospital, 55 Fruit Street, Boston, MA 02114, USA. Electronic address:

Study Objective: To assess whether, in a lung resection cohort with a low probability of confounding by indication, higher FiO is associated with an increased risk of impaired postoperative oxygenation - a clinical manifestation of lung injury/dysfunction.

Design: Pre-specified registry-based retrospective cohort study.

Setting: Two large academic hospitals in the United States.
