    Title translation When and why start insulin in type 2 diabetes?.
    Abstract Insulin initiation is a major step in medical management and life of patients with type 2 diabetes. Insulin is necessary if combination of 2 or 3 oral antidiabetic agents fail to achieve target glycemic goals, especially if HbA1c are superior to 1% from target or weight loss. Insulin will be started with bedtime intermediate-acting insulin. Insulin can be initiated with 10 units or 0.2 units/kg then increase by 2 units every 3 days until fasting levels are consistantly in targets range. If hypoglycemia occurs, insulin dose will be reduced by 4 units. Insulin initiation requires specific educational program for the acceptation of injection and to learn insulin injection, capillary blood glucose test and adjustment of insulin regimens.

    Abstract Although a lot of research and development has been done to understand and master the major physics involved in cryogenic rocket engines (combustion, feeding systems, heat transfer, stability, efficiency, etc.), the injection system and wall heat transfer remain critical issues due to complex physics, leading to atomization in the subcritical regime and the interactions of hot gases with walls. In such regimes, the fuel is usually injected through a coaxial annulus and triggers the atomization of the central liquid oxidizer jet. This type of injector is often referred to as air-assisted, or coaxial shear, injector, and has been extensively studied experimentally. Including such injection in numerical simulations requires specific models as simulating the atomization process is still out of reach in practical industrial systems. The effect of the injection model on the flame stabilization process and thus on wall heat fluxes is of critical importance when it comes to the design of wall-cooling systems. Indeed, maximizing the heat flux extracted from the chamber can lead to serious gain for the cooling and feeding systems for expander-type feeding cycles where the thermal energy absorbed by the coolant is converted into kinetic energy to drive the turbo-pumps of the feeding system. The methodology proposed in this work to numerically predict the flame topology and associated heat fluxes is based on state-of-the-art methods for turbulent reactive flow field predictions for rocket engines, including liquid injection, combustion model, and wall treatment. For this purpose, high-fidelity Large Eddy Simulation Conjugate Heat Transfer, along with a reduced kinetic mechanism for the prediction of H2/O2 chemistry, liquid injection model

    Abstract End-stage kidney disease (ESKD) is a multifactorial condition influenced by genetic background, but the extent to which a genetic risk score (GRS) improves ESKD prediction is unknown. We built a redox GRS on the base of previous association studies (six polymorphisms from six redox genes) and tested its relationship with ESKD in three cohorts of people with type 1 diabetes. Among 1012 participants, ESKD (hemodialysis requirement, kidney transplantation, eGFR < 15 mL/min/1.73 m

    Abstract Aims: Real-world data are required to support glucagon-like peptide-1 receptor agonist use in type 2 diabetes (T2D). SURE France assessed once-weekly semaglutide in adults with T2D in real-world clinical practice.
    Materials and methods: This multicentre, prospective, open-label, single-arm study included adults with T2D and ≥1 documented glycated haemoglobin (HbA1c) value ≤12 weeks before semaglutide initiation. The primary endpoint was HbA1c change from baseline to end of study (EOS; ~30 weeks). Secondary endpoints included change from baseline to EOS in body weight (BW) and waist circumference (WC); and proportion achieving HbA1c targets. Baseline characteristics and safety were reported for the full analysis set (patients initiating semaglutide). Analysis of other endpoints was based on the effectiveness analysis set (study completers receiving semaglutide at EOS).
    Results: Of 497 patients initiating semaglutide (41.6% female, mean age 58.3 years), 348 completed the study on treatment. Baseline HbA1c, diabetes duration, BW and WC, were 8.3%, 10.0 years, 98.2 kg and 114.2 cm, respectively. The most common reasons for initiating semaglutide were to improve glycaemic control (79.7%), reduce BW (69.8%) and address cardiovascular risk (24.1%). At EOS, mean changes were: HbA1c, -1.2% points [95% confidence interval (CI) -1.32; -1.10]; BW, -4.7 kg (95% CI -5.38; -4.07); and WC, -4.9 cm (95% CI -5.94; -3.88). At EOS, 81.7%, 67.7% and 51.6% of patients achieved an HbA1c target of <8.0%, <7.5% and <7.0%, respectively. No new safety concerns were identified.
    Conclusions: These results support the benefits of semaglutide in a real-world setting in adults with T2D in France showing a significant reduction in HbA1c and body weight.

    Abstract In a recent meta-analysis of randomized controlled trials of sodium glucose co-transporter 2 inhibitors (SGLT2i) in patients with diabetes, Lin and colleagues showed a positive association between SGLT2i-induced blood pressure and weight reduction and the risk of lower limb events. These results support the potential mechanism of a volume depletion effect of SGLT2i to explain the increase risk of amputation observed with this pharmacological class. Since the first result of the CANVAS trial raised a concern regarding the risk of amputation with SGLT2i, this hypothesis emerged from studies showing a higher incidence of amputations in patients with diabetes using diuretics. Furthermore, recent data found that copeptin, a surrogate marker of hydration status was also associated with lower limb outcomes. In conclusion, this assumption of diuretic-induced hypovolemia explanation highlights the fact that medications that induce a contraction of plasma volume, both traditional and novel agents with a diuretic mode of action should be introduced cautiously in patients with diabetes at high risk of diabetic foot events.

    Abstract After presentations of the principles of limb salvage and soft-tissue coverage for Gustilo III open tibia fractures, this third part is dedicated to management of tibial non-unions in low-resource settings. Inter-tibiofibular grafting and the induced membrane technique are preferred because they make it possible to deal with almost all situations. Key technical points of these methods are presented, followed by treatment guidelines based on Catagni's classification and bone defect size.

    Abstract After limb salvage based on debridement and external fixation, Gustilo IIIB open tibia fractures must undergo soft-tissue repair within 7 days. In low-resource setting, the coverage is performed with pedicled flaps only, which can be used by any orthopedic surgeon after minimal training. The authors describe here the simplified use of 7 basic flap transfers that can deal with almost all soft tissue defects. The diffusion of these techniques in developing countries is crucial for limiting functional and trophic effects related to prolonged exposure of the fracture site.
