Long‐term effectiveness of recommended boosted protease inhibitor‐based antiretroviral therapy in Europe

Objectives

The aim of the study was to evaluate the long‐term response to antiretroviral treatment (ART) based on atazanavir/ritonavir (ATZ/r)‐, darunavir/ritonavir (DRV/r)‐, and lopinavir/ritonavir (LPV/r)‐containing regimens.

Methods

Data were analysed for 5678 EuroSIDA‐enrolled patients starting a DRV/r‐, ATZ/r‐ or LPV/r‐containing regimen between 1 January 2000 and 30 June 2013. Separate analyses were performed for the following subgroups of patients: (1) ART‐naïve subjects (8%) at ritonavir‐boosted protease inhibitor (PI/r) initiation; (2) ART‐experienced individuals (44%) initiating the new PI/r with a viral load (VL) ≤500 HIV‐1 RNA copies/mL; and (3) ART‐experienced patients (48%) initiating the new PI/r with a VL >500 copies/mL. Virological failure (VF) was defined as two consecutive VL measurements >200 copies/mL ≥24 weeks after PI/r initiation. Kaplan–Meier and multivariable Cox models were used to compare risks of failure by PI/r‐based regimen. The main analysis was performed with intention‐to‐treat (ITT) ignoring treatment switches.

Results

The time to VF favoured DRV/r over ATZ/r, and both were superior to LPV/r (log‐rank test; P < 0.02) in all analyses. Nevertheless, the risk of VF in ART‐naïve patients was similar regardless of the PI/r initiated after controlling for potential confounders. The risk of VF in both treatment‐experienced groups was lower for DRV/r than for ATZ/r, which, in turn, was lower than for LPV/r‐based ART.

Conclusions

Although confounding by indication and calendar year cannot be completely ruled out, in ART‐experienced subjects the long‐term effectiveness of DRV/r‐containing regimens appears to be greater than that of ATZ/r and LPV/r.

     

Assessment of Platelet REACtivity After Transcatheter Aortic Valve Replacement: The REAC-TAVI Trial

Objectives

The REAC-TAVI (Assessment of platelet REACtivity after Transcatheter Aortic Valve Implantation) trial enrolled patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) pre-treated with aspirin + clopidogrel, aimed to compare the efficacy of clopidogrel and ticagrelor in suppressing high platelet reactivity (HPR) after TAVI.

Evaluación multimodal de la degeneración estructural de válvulas percutáneas en el seguimiento a largo plazo

Introduction and objectivesWe assessed the long-term hemodynamic performance of transcatheter heart valve (THV) by paired transthoracic echocardiography (TTE), and the incidence, characteristics and factors associated with THV structural valve degeneration (SVD).MethodsA total of 212 patients who underwent transcatheter aortic valve replacement and had a potential follow-up > 5 years with at least 1 TTE ≥ 1-year postprocedure were included. All patients had a TTE at 1 to 5 years and 36 had another one at 6 to 10 years. SVD was defined as subclinical (increase > 10 mmHg in mean transvalvular gradient +  decrease > 0.3 cm² in valve area and/or new-onset mild or moderate aortic regurgitation) and clinically relevant (increase > 20 mmHg in mean transvalvular gradient + decrease > 0.6 cm² in valve area and/or new-onset moderate-to-severe aortic regurgitation). Fifteen patients had a transesophageal echocardiography at the time of SVD diagnosis, and 85 an opportunistic computed tomography examination at 1 (0.5-2) years.ResultsTransvalvular mean gradient increased and valve area decreased over time (P < .01). At 8 years of follow-up, SVD occurred in 30.2% of patients (clinically relevant: 9.3%). Transesophageal echocardiography revealed thickened and reduced-mobility leaflets in 80% and 73% of SVD cases, respectively. No baseline or procedural factors were associated with SVD. THV underexpansion (3.5%) or eccentricity (8.2%) had no impact on valve hemodynamics/SVD at follow-up.ConclusionsA gradual THV hemodynamic deterioration occurred throughout a 10-year period, leading to SVD in ～30% of patients (clinically relevant in < 10%). Leaflet morphology/mobility were frequently impaired in SVD cases, but THV geometry did not influence valve hemodynamics or SVD.     

Comprehensive Treatment of Periorbital Region with Hyaluronic Acid

The periorbital subunit is one of the first facial regions to show signs of aging, primarily due to volume depletion of the soft tissue and bony resorption. Surgical and office-based nonsurgical procedures form an important basis for periorbital rejuvenation. It is important to make a detailed clinical evaluation of the patient to indicate the most appropriate procedure to be performed. With the objective of showing a nonsurgical procedure for the rejuvenation of the periorbital area, the authors describe a technique of applying fillers in the upper and lower periorbital regions, paying attention to the anatomy of this facial region and the type of product to be used besides the expected results of the procedure and its possible adverse effects and complications. The nonsurgical rejuvenation of the periorbicular region with hyaluronic acid is a new and innovative technique. In the opinion of the authors, it is a great aesthetic impact area and consequently brings high satisfaction to patients.Maintaining a youthful and pleasant appearance of the face in today’s culture impacts quality of life in many patients. The facial contour remodeling is being revolutionized by new nonsurgical techniques.Facial aging is a complex and dynamic process. All people age differently as a result of imbalance, disharmony, and disproportion of the aging process between the overlying soft tissue and the underlying bony frameworks.1 The upper periorbital subunit is one of the first facial regions to show signs of aging, and even minor changes in its structure and volume can distort the perceived emotions and health of patients.2 An aesthetic and youthful upper periorbital subunit is characterized by a well-defined brow of appropriate height and shape, fullness of the upper periorbit, a crisp and well-defined upper eyelid crease, minimal skin excess, and good skin quality.3,4In the aging process of this facial area, one group of patients displays signs of aging due predominantly to soft tissue ptosis of the upper eyelid, requiring surgical excision. Another group presents with volume depletion of the soft tissue and bony resorption of the orbit. The loss of septal support, leading to brow prolapse and an exacerbation of upper eyelid fullness and congestion, can also contribute to the aging process. This appearance is characterized by deflation of the upper eyelid as well as hollowing and visibility of the supraorbital bony rim, leading to a sunken, hollow, and skeletonized orbit, which can make the patient appear sickly, anorexic, and old. In recent years, modern facial rejuvenation surgery has evolved toward volume restoration in addition to tissue suspension.2Comprehensive analysis of both soft tissue and bony structural changes are essential for the periorbital rejuvenation. Surgical procedures and office-based nonsurgical procedures form an important basis for periorbital rejuvenation, including cosmeceuticals, chemical peels, laser and light treatments, neurotoxins, and fillers. Improved understanding of the pathophysiology of aging and technical advancements in nonsurgical techniques has enabled us to achieve better and more comprehensive improvement for patients.5
