攀枝花市卫生计生委，依据《中华人民共和国执业医师法》《医疗事故处理条例》等相关法律法规，责令西区卫生计生局对承担主要责任的攀枝花宏实医院及其涉责医务人员作出处理：吊销攀枝花宏实医院《医疗机构执业许可证》；吊销主持术前讨论和手术主刀的医生文莉琼《医师执业证书》；吊销器械护士苏阿芹《护士执业证书》；吊销巡回护士周燕《护士执业证书》；暂停参与术前讨论的医生胡晓峰执业活动。

伤口爱好者，如何避免，如何避免不发生在自己身上?

想必大家都熟悉——难愈合性伤口患者，多个医院间周转，如同旅行度假，不断换环境！

这个事件让我想起6年的一个难愈合性伤口患者，曾辗转八家医院，伤口也未能愈合，最后手术时发现伤口基地残留纱布是罪魁祸首，患者和家属将七家医院告上了法庭，我写了辩护书，操作记录没有使用纱布，最后证明纱布与本院无关，想想仍然心有余悸！

还有另外一个案例，臀部脓肿患者，在门诊切开引流，反复不愈合2月，住院治疗，负压引流后肿痛减轻，再次至手术室清创时，发现基地有一个纱布，术前的MR居然没看到纱布！原因：门诊外科医生切开脓肿，填塞纱布，门诊伤口护士换药，没有注意到纱布！

从事伤口治疗者，需要警惕这个问题——伤口、窦道异物残留！

这不仅是医疗事故，还是故意杀人；不是技术问题，而是责任问题，而且是不可原谅的错误！

我们需要警惕各种伤口内的填塞物：纱布、各种敷料、负压海绵等等！

尽量做到谁放入，谁取出，最好有记录！

避免伤口内残留异物——警钟长鸣！

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.

ABSTRACT

Nowadays, numerous skincare routines are used to rejuvenate aging skin. Retinoids are one of the most popular ingredients used in antiaging treatments. Among the representatives of retinoids, tretinoin is considered the most effective agent with proven antiaging effects on the skin and can be found in formulations approved as medicines for topical treatment of acne, facial wrinkles, and hyperpigmentation. Other retinoids present in topical medicines are used for various indications, but only tazarotene is also approved as adjunctive agent for treatment of facial fine wrinkling and pigmentation. The most commonly used retinoids such as retinol, retinaldehyde, and retinyl palmitate are contained in cosmeceuticals regulated as cosmetics. Since clinical efficacy studies are not required for marketing cosmetic formulations, there are concerns about the efficacy of these retinoids.

From a formulation perspective, retinoids pose a challenge to researchers as a result of their proven instability, low penetration, and potential for skin irritation. Therefore, novel delivery systems based on nanotechnology are being developed to overcome the limitations of conventional formulations and improve user compliance. In this review, the clinical evidence for retinoids in conventional and nanoformulations for topical antiaging treatments was evaluated. In addition, an overview of the comparison clinical trials between tretinoin and other retinoids is presented. In general, there is a lack of evidence from properly designed clinical trials to support the claimed efficacy of the most commonly used retinoids as antiaging agents in cosmeceuticals. Of the other retinoids contained in medicines, tazarotene and adapalene have clinically evaluated antiaging effects compared to tretinoin and may be considered as potential alternatives for antiaging treatments. The promising potential of retinoid nanoformulations requires a more comprehensive evaluation with additional studies to support the preliminary findings.

Keywords: Antiaging; Clinical evidence; Cosmeceuticals; Nanoformulations; Retinoids; Retinol; Tretinoin

Key Summary Points

Tretinoin is the retinoid present in medicines for topical application with the strongest clinical evidence of antiaging Tazarotene and adapalene may be considered as tretinoin alternatives for antiaging treatments.

Clinical evidence is lacking for retinoids contained in cosmeceuticals for topical antiaging treatments.

Novel formulations based on nanotechnology are being developed to overcome the major drawbacks of retinoid Further evaluation with in vivo testing and clinical trials are needed to support the preclinical results for the developed nanoformulations containing retinoids.
