Liposuction versus conservative therapy for patients with lipoedema in Germany: a multicentre, randomised controlled clinical trial.

September 5, 2026| Source: Lancet (London, England)

Lipoedema is a painful, chronic disease of the subcutaneous adipose tissue, predominantly affecting women. Conservative complex decongestive therapy is the standard of care but offers limited symptom relief. Liposuction appears to be a promising approach but lacks evidence of effectiveness and safety. The aim of this trial was to show superiority of liposuction compared with conservative therapy regarding relevant pain reduction with reasonable safety. In this multicentre, randomised controlled trial at 11 German centres, eligible women with stage I, II, or III lipoedema and leg pain of at least 4 points on a 0-10 numeric rating scale received conservative therapy for up to 7 months and then were randomly assigned to liposuction or conservative therapy (2:1) stratified by lipoedema stage and study site. For all visits involving an assessment, patches were applied to the legs of all patients, and patients were instructed not to reveal the treatment they had received, in order to mask the assessor. The primary endpoint was reduction of patient-reported leg pain by at least 2 points after 12 months, and missing assessment was considered non-successful.The primary outcome was analysed in the intention-to-treat population which included all randomly assigned patients, and safety analysis included all enrolled patients. A long-term follow-up of 36 months is ongoing. This study is registered at ClinicalTrials.gov, NCT04272827. Of 1973 patients screened between Jan 19, 2021, and June 7, 2022, 453 were enrolled, and 410 were randomly assigned to the liposuction group (n=278) or to the conservative therapy group (n=132). All 410 patients were included in the intention-to-treat analysis (mean age 42·9 [ SD 10·6]; ethnicity data were not collected). After 12 months, 190 (68%) of 278 randomisly assigned patients undergoing liposuction achieved the primary endpoint of pain reduction versus ten (8%) of 132 randomly assigned to conservative therapy (odds ratio 26·2 [95% CI 13·1-52·5]; p<0·0001). Adverse events occurred in 124 (47%) of 265 patients undergoing liposuction, and 20 (8%) of 265 were rated as serious. In the conservative therapy group, 30 (21%) of 145 patients reported adverse events, and five (3%) 145 were rated as serious. Secondary endpoints regarding quality of life showed greater improvement in the liposuction group. Liposuction was superior to conservative therapy in reducing leg pain and improving quality of life in patients with lipoedema, but was associated with a higher rate of serious adverse events. Liposuction has the potential to be a promising treatment option for patients with lipoedema. The Federal Joint Committee, Germany.

Chronic cigarette smoke exposure induces distinct stem cell states driving genetic driver-specific non-small cell lung cancer subtypes.

Cigarette smoke-induced chronic inflammation (CI) potentiates development of non-small cell lung cancer (NSCLC) by mediating genetic and epigenetic events. Using normal lung organoids (LOs), we define how chronic cigarette smoke condensate (CSC) exposure drives two separate stem cell populations to evolve premalignant states harboring progressive epigenetic and linked transcriptomic abnormalities in the absence of major driver mutations. These dynamics facilitate evolution of an immune evasive s

Extended fractional Hofstadter states at high field in twisted bilayer graphene above the magic angle.

When a Chern band is partially filled, a fractional Chern insulator (FCI)-the lattice analog of a fractional quantum Hall state-can arise. Though the full range of possible scenarios for producing such a state is not established, the most tractable models combine strong electronic interactions with the quantum geometry of the parent Chern band meeting specific criteria. In twisted bilayer graphene, the importance of interactions can be tuned by varying the interlayer twist. Here, we study a samp

Phenotypic screening identifies kenpaullone as a prolymphangiogenic compound to improve heart repair following myocardial infarction.

Myocardial infarction (MI) induces cardiac muscle death and its subsequent replacement by a noncontractile fibrotic scar, which underlies progression to heart failure. Current treatments restore blood flow and assist with cardiac workload but do not promote regeneration. We have previously shown endogenous growth of the cardiac lymphatic system following MI and further stimulation with the lymphatic endothelial specific mutated Vascular Endothelial Growth Factor-C (VEGF-C) isoform, VEGFC-C156S,

Dopamine suppresses pathological retinal oscillations and enhances the signal-to-noise ratio.

Infantile nystagmus is a debilitating involuntary eye movement disorder often associated with retinal diseases such as congenital stationary night blindness (CSNB). The oscillating eye movements of infantile nystagmus come with reduced visual acuity and strongly impair quality of life. No cure exists for this condition. Previously, we demonstrated that nystagmus in the CSNB mouse model Nyx nob has a retinal cause. Specifically, we found that synchronized oscillations of retinal ganglion cells (R

Spatial and single-nucleus transcriptomics reveals the molecular pathology of type 2 diabetes-associated cognitive dysfunction.

The mechanisms underlying type 2 diabetes-associated cognitive dysfunction (DACD) remain poorly understood, hindering therapeutic progress. Here, we integrated spatial transcriptomics and single-nucleus RNA sequencing to delineate the spatiotemporal molecular and cellular landscape of DACD in brain tissues from 3- and 6-mo-old mouse models. Our findings revealed region- and cell-type-specific transcriptomic alterations, with excitatory neurons in the hippocampus and isocortex emerging as the mos
