Lymphedema, a severe and complex inflammatory disease caused by lymphatic system insufficiency and impeded lymphatic drainage that causes an enormous physical and psychological burden on patients and may even lead to death, has long been a challenging issue in the medical field. Clinically, conventional approaches including surgical treatment and conservative treatment have been employed for lymphedema therapy, but their curative effect is still unsatisfactory because of high operational difficulty, high cost, and long-term reliance. In this study, a novel kind of piezoelectric microneedle driven by ultrasound (US) is proposed to regulate macrophage polarization and remodel the pathological inflammatory microenvironment in a noninvasive manner, thereby promoting lymphatic regeneration and improving lymphedema.

Background: Current diagnostic imaging modalities have limited ability to differentiate between malignant and benign pancreaticobiliary disease, and lack accuracy in detecting lymph node metastases. F-Prostate-Specific Membrane Antigen (PSMA) PET/CT is an imaging modality used for staging of prostate cancer, but has incidentally also identified PSMA-avid pancreatic lesions, histologically characterized as pancreatic ductal adenocarcinoma (PDAC). This phase I/II study aimed to assess the feasibility of F-PSMA PET/CT to detect PDAC.

Introduction: Given the projected rise in the incidence of cancer treatment-related conditions, such as lymphoedema, and the limited research on lymphoedema in cancers with poor prognoses, there is a need for a better understanding of cancer-related lymphoedema incidence and associated risk factors across all types of cancers. The objectives of this review are (1) to produce a resource on an open-access platform that facilitates continuous update of incidence estimates and risk factors as evidence emerges, (2) to provide the most up-to-date estimate of the incidence of cancer-related lymphoedema and (3) to evaluate the strength and consistency of the association between lymphoedema and cancer treatment and non-treatment-related risk factors.
Methods And Analysis: A living systematic and grey literature search will be conducted to identify studies reporting the incidence, prevalence of lymphoedema or associated risk factors in individuals who have undergone treatment for any type of cancer.
Advances in surgical management of chronic lymphedema: current strategies and future directions.

Lymphedema is a chronic condition caused by the accumulation of protein-rich fluid in the interstitial tissue, resulting in edema and a diminished quality of life. When first-line treatments like complete decongestive therapy (CDT) fail, surgical options are considered. These include physiological procedures like lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT), which aim to restore lymphatic function, as well as reductive procedures such as liposuction and excisional techniques, which reduce limb volume.

Brain glymphatic activity, as indicated by diffusion-tensor imaging analysis along the perivascular space (ALPS) index, is involved in developmental neuropsychiatric and neurodegenerative diseases, but its genetic architecture is poorly understood. Here, we identified 17 unique genome-wide significant loci and 161 candidate genes linked to the ALPS-indexes in a discovery sample of 31,021 individuals from the UK Biobank. Seven loci were replicated in two independent datasets.
