Abstract Background The facial aging process entails alterations in the volume, shape, and texture of all skin layers over time. Calcium hydroxyapatite (CaHA) is a well-established safe skin filler with unique properties to resolve some skin alterations by stimulating neocollagenesis. The vectoral-lift (V-lift) technique targets the global repositioning of facial structures by addressing distinct anatomical injection planes. It includes deep facial augmentation with Radiesse PlusTM to retain ligament restructuring and superficial subcutaneous enhancement with diluted Radiesse DuoTM. Herein, we present cases that illustrate the use of this approach.

Methods This pilot study enrolled 36 participants (33 women and three men; ages 37–68 years) in a Brazilian clinical setting, and all patients underwent a single treatment. Photographs were taken at rest, in frontal and oblique views, before injection, and 90 days after treatment.

Results Treatment resulted in elevation of the upper and middle face, notable improvements in the infraorbital hollow, and adjustment of the mean facial volume.

Conclusions The V-lift technique is a three-dimensional pan-facial treatment that relies on ligament support and face vectoring to obtain a lifting effect and facial contour restoration. It encompasses deep facial augmentation involving the use of Radiesse PlusTM for restructuring and retaining ligaments and Radiesse DuoTM for superficial subcutaneous enhancement. This approach targets a global repositioning of the facial structures by addressing distinct anatomical injection planes. It achieves a repositioning of the overall facial anatomy without requiring a substantial volumetric expansion.

Abstract

Background Various techniques have been employed in aesthetic medicine to combat skin aging, in particular that of the facial region. Hyaluronic acid is utilized to enhance moisture levels and extracellular matrix molecules. This study aims to histologically assess the efects of low molecular weight hyaluronic acid fragments combined with amino acids (HAAM) on facial skin rejuvenation through intradermal microinjections.

Methods A total of twenty women, with an average age of 45 and ranging from 35 to 64 years old, participated in the study, including 8 in menopause and 12 in the childbearing age group. Mesotherapy was used to administer HAAM to the patients. Prior to and three months after the treatment, each patient underwent small circular punch biopsies. Ultrasound examinations were conducted using B-mode, capturing 2D images in longitudinal or transverse orientations with frequencies ranging from 5 to 13 Mega-hertz (MY LAB X8, ESAOTE, Genova, Italy). A total of 60 ultrasound examinations were taken, with 30 collected before treatment and 30 after treatment.

Results The histological analysis demonstrates an increase in fbroblast activity resulting in the production of Type III reticular collagen, as well as an increased number of blood vessels and epidermal thickness. However, the analysis of ultrasound data before and after treatment showed no statistical diference in skin thickness in malar area, chin and mandibular angle.

Conclusions Histological assessments indicate that subcutaneous infltration of HAAM has a substantial impact on the dermis of facial skin.

Key Points

Question Are glucagon-like peptide 1 receptor agonists (GLP-1RAs) associated with kidney disease progression?

Findings In this genetic association study of 353 153 adults, higher genetic GLP1R gene expression as a proxy for GLP-1RAs was associated with a small reduction in the risk of kidney disease progression, even after adjusting for obesity and diabetes.

Meaning These findings support a nephroprotective role of GLP-1RAs.

Abstract

IMPORTANCE Glucagon-like peptide 1 receptor agonists (GLP-1RAs) may have nephroprotective properties beyond those related to weight loss and glycemic control.

OBJECTIVE To investigate the association of genetically proxied GLP-1RAs with kidney disease

DESIGN, SETTING, AND PARTICIPANTS This genetic association study assembled a national retrospective cohort of veterans aged 18 years or older from the US Department of Veterans Affairs Million Veteran Program between January 10, 2011, and December 31, 2021. Data were analyzed from November 2023 to February 2024.

EXPOSURES Genetic risk score for systemic GLP1R gene expression that was calculated for each study participant based on genetic variants associated with GLP1R mRNA levels across all tissue samples within the Genotype-Tissue Expression project.

MAIN OUTCOMES AND MEASURES The primary composite outcome was incident end-stage kidney disease or a 40% decline in estimated glomerular filtration rate. Cox proportional hazards regression survival analysis assessed the association between genetically proxied GLP-1RAs and kidney disease progression.

RESULTS Among 353 153 individuals (92.5% men), median age was 66 years (IQR, 58.0-72.0 years) and median follow-up was 5.1 years (IQR, 3.1-7.2 years). Overall, 25.7% had diabetes, and 45.0% had obesity. A total of 4.6% experienced kidney disease progression. Overall, higher genetic GLP1R gene expression was associated with a lower risk of kidney disease progression in the unadjusted model (hazard ratio [HR], 0.96; 95% CI, 0.92-0.99; P = .02) and in the fully adjusted model accounting for baseline patient characteristics, body mass index, and the presence or absence of diabetes (HR, 0.96; 95% CI, 0.92-1.00; P = .04). The results were similar in sensitivity analyses stratified by diabetes or obesity status.

CONCLUSIONS AND RELEVANCE In this genetic association study, higher GLP1R gene expression was associated with a small reduction in risk of kidney disease progression. These findings support pleiotropic nephroprotective mechanisms of GLP-1RAs independent of their effects on body weight and glycemic control.
