Background: Breast cancer-related lymphedema (BCRL) is a debilitating sequela affecting up to 1 in 3 breast cancer survivors. Treatments are palliative and do not address the underlying lymphatic injury. Recent preclinical and nonrandomized studies have shown promising results using adipose-derived regenerative cells (ADRCs) and lipotransfer in alleviating BCRL through regeneration of lymphatic tissue. However, no randomized controlled trial has been performed in an attempt to eliminate a placebo effect., Methods: This randomized, double-blind, placebo-controlled trial included patients with no-option, persistent disabling unilateral BCRL. Patients were randomly assigned in a 1:1 ratio to receive either autologous ADRCs (4.20×10 7 ± 1.75×10 7 cells) and 30-cc lipotransfer or placebo (saline) to the axilla. The primary outcome was a change in BCRL volume 1 year after treatment. Secondary outcomes included changes in quality of life, indocyanine green lymphangiography stage, bioimpedance, and safety., Results: Eighty patients were included, of whom 39 were allocated to ADRCs and lipotransfer treatment and 41 to placebo treatment. Baseline characteristics were similar in the groups. One year after treatment, no objective improvements were observed in the treatment or placebo groups. In contrast, significant subjective improvements were noted for both the treatment and placebo groups., Conclusions: This trial failed to confirm a benefit of ADRCs and lipotransfer in the treatment of BCRL. These nonconfirmatory results suggest that ADRC and lipotransfer should not be recommended for alleviating BCRL. However, the authors cannot exclude that repeated treatments or higher doses of ADRCs or lipotransfer could yield a clinical effect., Clinical Question/level of Evidence: Therapeutic, I., (Copyright © 2024 by the American Society of Plastic Surgeons.)

Study Design: Register-based cohort study based on linked data from multiple national registries., Objective: To describe the sociodemographic and health characteristics of individuals in Denmark with osteoporotic vertebral fractures (OVF) and analyze time trends. The study compares labor market participation and comorbidities between OVF patients and a matched control group without these fractures., Summary of Background Data: The incidence and characteristics of OVF patients in Denmark are not well-documented. Multiple national health and economic registries enable linking of individual patient data, providing new insights., Methods: We identified individuals with hospital-diagnosed vertebral compression fractures from 2010 to 2018 using the Danish National Patient Register. A control group was matched by sex, age, and municipality. Work status prior to OVF was categorized as employed, on paid sickness benefit, in early retirement, or on old-age pension. Comorbidities were analyzed based on hospital diagnoses within 10 years prior to the fracture., Results: During 2010 to 2018, 20.262 individuals had a hospital contact with an OVF. Sixty-four percent were women and the mean age was 73.6 (SD 12.4) years. OVF incidence increased from 86 in 2010 to 142 per 100,000 persons in 2018. In 2018, the regional incidence ranged from 120 to 154 per 100,000. More than a fifth of the patients were working prior to the fracture, while 77% were in early retirement or old-age pension. The population with OVF had more comorbidities than the matched comparison group., Conclusion: The incidence of hospital-diagnosed OVFs has risen over the last decade, with regional differences. Notably, over 20% of OVF patients were still employed, highlighting the socioeconomic impact of this condition., Competing Interests: Conflicts of interest: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (Copyright © 2024 Wolters Kluwer Health, Inc.

Introduction: Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are common inflammatory conditions. The diagnosis of PMR/GCA poses many challenges since there are no specific diagnostic tests. Recent literature emphasizes the ability of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) to assess global disease activity in inflammatory diseases. 18F-FDG PET/CT may lead to the diagnosis at an earlier stage than conventional imaging and may also assess response to therapy. With respect to the management of PMR/GCA, there are 3 significant areas of concern as follows: vasculitis process/vascular stiffness, malignancy, and osteoporosis., Methods and Analysis: All patients with suspected PMR/GCR referred to the Rheumatology section of Medicine Department at Svendborg Hospital, Denmark. The 4 separate studies in the current protocol focus on: the association of clinical picture of PMR/GCA with PET findings; the validity of 18F-FDG PET/CT scan for diagnosis of PMR/GCA compared with temporal artery biopsy; the prevalence of newly diagnosed malignancies in patients with PMR/GCA, or PMR-like syndrome, with the focus on diagnostic accuracy of 18F-FDG PET/CT scan compared with conventional workup (ie, chest X-ray/abdominal ultrasound); and the impact of disease process, and also steroid treatment on bone mineral density, body composition, and vasculitis/vascular stiffness in PMR/GCA patients., Ethics and Dissemination: The study has been approved by the Regional Ethics Committee of the Region of Southern Denmark (identification number: S-20160098) and Danish Data Protection Agency (J.nr 16/40522). Results of the study will be disseminated via publications in peer-reviewed journals, and presentation at national and international conferences.

Objectives: The purinergic P2RX7 receptor (P2RX7) has been shown to play a role in the regulation of osteoblast and osteoclast activity. The aim of this study was to determine the presence of polymorphisms in exon 13 of the P2X7 gene and the association with osteoclast apoptosis in vitro and bone status in vivo., Methods: A total of 1764 postmenopausal women were genotyped for three single nucleotide polymorphisms detected after sequencing of exon 13 of P2X7. Bone markers, bone mineral density of the hip and lumbar spine were determined at baseline and after 10 years, and vertebral fracture incidence after 10 years. In-vitro ATP-induced caspase-1 determinations were performed on osteoclasts from the different genotypes., Results: Three polymorphisms were detected (Gln460Arg, Glu496Ala, and Ile568Asn). None of the polymorphisms was related to bone mineral density or changes in bone mineral density over 10 years in hormone replacement therapy naïve women. The Ile568Asn polymorphism was however, associated with effect of hormone replacement therapy. Furthermore, the 10-year fracture incidence was significantly associated with both the Glu496Ala and the Ile568Asn. The Glu496Ala polymorphism was closely related to ATP-induced osteoclast apoptosis in vitro, as osteoclasts from individuals homozygous for the C allele had significantly decreased apoptotic activity., Conclusion: The P2X7 Glu496Ala and the Ile568Asn single nucleotide polymorphisms are associated with 10-year fracture risk in postmenopausal women and response to hormone replacement therapy treatment. Further, the Glu496Ala polymorphism is strongly influencing osteoclast apoptosis in vitro, which could contribute to increased fracture risk.

Background: Improvement in endothelial function may be an important mechanism by which estrogen replacement therapy protects postmenopausal women against coronary artery disease. However, combined hormone replacement therapy is more frequently used owing to the risk of uterine cancer with estrogen-only therapy. Concurrent progesterone treatment may attenuate the beneficial effects of estrogens not only on the lipid profile but also on the endothelium., Methods and Results: We studied endothelial vasomotor function in 100 healthy postmenopausal women aged 53.3+/-2.9 years randomized to either combined hormone replacement therapy (n=46) or no substitution (n=54) 2.9+/-0.5 years earlier. In addition, 30 healthy premenopausal women aged 30.3+/-4.2 years were studied. With external ultrasound, brachial artery diameter was measured at rest, during reactive hyperemia (with increased flow causing endothelium-dependent dilation), and after sublingual nitroglycerin (causing endothelium-independent dilation). Compared with premenopausal women, flow-mediated dilation was significantly reduced in both postmenopausal groups. In the postmenopausal women, total cholesterol was lower in the treated women (5.66+/-0.83 versus 6.13+/-0.92 mmol/L; P=.025), whereas HDL cholesterol was similar (1.91+/-0.53 versus 1.85+/-0.46 mmol/L; P=NS). Dilation to flow and to nitroglycerin was similar in the two postmenopausal groups (flow: 2.5+/-2.9% versus 2.2+/-2.2%, P=NS; nitrate: 18.7+/-5.9% versus 17.2+/-6.2%, P=NS)., Conclusions: Long-term combined oral hormone replacement therapy is without beneficial effects on endothelial vasomotor function in healthy postmenopausal women. This supports the view that progesterone may attenuate the beneficial effects of unopposed estrogen replacement.
