Preliminary Single-Cell RNA-Sequencing Analysis Uncovers Adipocyte Heterogeneity in Lipedema
Despite its increasing incidence and prevalence throughoutWestern countries,
lipedema continues to be a very enigmatic disease, often misunderstood or misdiagnosed by the medical
community and with an intrinsic pathology that is difficult to trace. The nature of lipedemic tissue
is one of hypertrophic adipocytes and poor tissue turnover. So far, there are no identified pathways
responsible, and little is known about the cell populations of lipedemic fat. Methods: Adipose tissue
samples were collected from affected areas of both lipedema and healthy participants. For single-cell
RNA sequencing analysis, the samples were dissociated into single-cell suspensions using enzymatic
digestion and then encapsulated into nanoliter-sized droplets containing barcoded beads. Within each
droplet, cellular mRNA was converted into complementary DNA. Complementary DNA molecules
were then amplified for downstream analysis. Results: The single-cell RNA-sequencing analysis revealed
three distinct adipocyte populations at play in lipedema. These populations have unique gene
signatures which can be characterized as a lipid generating adipocyte, a disease catalyst adipocyte,
and a lipedemic adipocyte. Conclusions: The single-cell RNA sequencing of lipedemic tissue samples
highlights a triad of distinct adipocyte subpopulations, each characterized by unique gene signatures
and functional roles. The interplay between these adipocyte subtypes offers promising insights into
the complex pathophysiology of lipedema
Autologous Lipofilling Improves Clinical Outcome in Patients With Symptomatic Dermal Scars Through Induction of a Pro-Regenerative Immune Response
BACKGROUND: Autologous lipofilling is an emerging procedure to treat and possibly reverse dermal scars and to reduce scar-related pain, but its efficacy and mechanisms are poorly understood. OBJECTIVES: The aim of this study was to test the hypothesis that repeated lipografts reverse dermal scars by reinitiation of wound healing. METHODS: In a prospective, non-placebo-controlled clinical study, 27 adult patients with symptomatic scars were given 2 lipofilling treatments at 3-month intervals. As primary outcome, clinical effects were measured with the Patient and Observer Scar Assessment Scale (POSAS). Scar biopsies were taken before and after treatments to assess scar remodeling at a cellular level. RESULTS: Twenty patients completed the study. Patients’ scars improved after lipofilling. The total POSAS scores (combined patient and observer scores) decreased from 73.2  [14.7] points (mean [standard deviation]) pretreatment to 46.1 [14.0] and 32.3 [13.2] points after the first and second lipofilling treatment, respectively. Patient POSAS scores decreased from 37.3 [8.8] points to 27.2 [11.3] and 21.1 [11.4] points, whereas observer POSAS scores decreased from 35.9 [9.5] points to 18.9 [6.0] and 11.3 [4.5] points after the first and second treatment, respectively. After each lipofilling treatment, T lymphocytes, mast cells, and M2 macrophages had invaded scar tissue and were associated with increased vascularization. In addition, the scar-associated epidermis showed an increase in epidermal cell proliferation to levels similar to that normal in skin. Moreover, lipofilling treatment caused normalization of the extracellular matrix organization towards that of normal skin. CONCLUSIONS: Autologous lipofilling improves the clinical outcome of dermal scars through the induction of a pro-regenerative immune response, increased vascularization, and epidermal proliferation and remodeling of scar tissue extracellular matrix.

Use of a Total Leg Fillet Flap to Cover Multiple Pelvic Pressure Ulcers
Summary:. The authors present the surgical strategy in the treatment of a morbidly obese paraplegic patient with a massive sacral pressure ulcer as well as bilateral trochanteric ulcers in a 1-step leg-sacrificing procedure utilizing the “spare-part” concept. It is the intention of the authors to reinforce the use of fillet flaps as a last resort option in paraplegic patients with pressure sores

Liposuction in the Treatment of Lipedema: A Longitudinal Study
Background Lipedema is a condition consisting of painful bilateral increases in subcutaneous fat and interstitial fluid in the limbs with secondary lymphedema and fibrosis during later stages. Combined decongestive therapy (CDT) is the standard of care in most countries. Since the introduction of tumescent technique, liposuction has been used as a surgical treatment option. The aim of this study was to determine the outcome of liposuction used as treatment for lipedema.
Methods Twenty-five patients who received 72 liposuction procedures for the treatment of lipedema completed a standardized questionnaire. Lipedema-associated complaints and the need for CDT were assessed for the preoperative period and during 2 separate postoperative follow-ups using a visual analog scale and a composite CDT score. The mean follow-up times for the first postoperative follow-up and the second postoperative follow-up were 16 months and 37 months, respectively.
Results Patients showed significant reductions in spontaneous pain, sensitivity to pressure, feeling of tension, bruising, cosmetic impairment, and general impairment to quality of life from the preoperative period to the first postoperative follow-up, and these results remained consistent until the second postoperative follow-up. A comparison of the preoperative period to the last postoperative follow-up, after 4 patients without full preoperative CDT were excluded from the analysis, indicated that the need for CDT was reduced significantly. An analysis of the different stages of the disease also indicated that better and more sustainable results could be achieved if patients were treated in earlier stages.
Conclusions Liposuction is effective in the treatment of lipedema and leads to an improvement in quality of life and a decrease in the need for conservative therapy
A Randomized, Triple-Blind, Placebo-Controlled, Add-On Clinical Trial to Evaluate the Efficacy of Emblica officinalis in Uncontrolled Hypertension
Introduction. Emblica officinalis (EO) has some cardiovascular effects, and there are some animal studies that show its antihypertensive effect. This study was conducted to determine the effect of combination of EO with standard therapy on the systolic blood pressure (SBP) and diastolic blood pressure (DBP) in patients with uncontrolled hypertension. Materials and Methods. This was a randomized, triple-blind, placebo-controlled, 8-week study. Ninety-two patients with uncontrolled hypertension despite taking hypotensive drugs were randomly assigned into two groups to take EO (500 mg/TDS after meal) or placebo in combination with standard antihypertensive drugs. After 2, 4, 6, and 8 weeks of intervention, SBP and DBP and heart rate (HR) were measured. Data were analyzed by SPSS software using repeated measures ANOVA. Results. Eighty-one patients (41 in the drug group and 40 in the placebo group) completed the study for 8 weeks and were analyzed. The mean ± standard deviation of age was 53.64 ± 10.01 years. SBP decreased as 15.6 ± 8.23% in the EO group and 6.3 ± 7.49% in the placebo group (P<0.001). DBP decreased as 12.3 ± 7.87% and 3.88 ± 7.98%, respectively (P<0.001). Time effect was not significant, but the group effect was significant (F = 13.875, P=0.001 for systolic BP and F = 18.948, P<0.001 for diastolic BP). No side effects were reported during the study. Conclusion. Eight-week combination therapy of EO with standard antihypertensive drugs significantly reduced the SBP and DBP more than placebo in patients with uncontrolled hypertension
Lipedema—Pathogenesis, Diagnosis, and Treatment Options
Background: Lipedema is often unrecognized or misdiagnosed; despite an estimated prevalence of 10% in the overall female population, its cause is still unknown. There is increasing awareness of this condition, but its differential diagnosis can still be challenging. In this article, we summarize current hypotheses on its pathogenesis and the recommendations of current guidelines for its diagnosis and treatment. Methods: This review is based on publications about lipedema that were retrieved by a selective search in the MEDLINE, Web of Science, and Cochrane Library databases. Results: The pathophysiology of lipedema remains unclear. The putative causes that have been proposed include altered adipogenesis, microangiopathy, and disturbed lymphatic microcirculation. No specific biomarker has yet been found, and the diagnosis is currently made on clinical grounds alone. Ancillary tests are used only to rule out competing diagnoses. The state of the evidence on treatment is poor. Treatment generally consists of complex decongestive therapy. In observational studies, liposuction for the permanent reduction of adipose tissue has been found to relieve symptoms to a significant extent, with only rare complications. The statutory health-insurance carriers in Germany do not yet regularly cover the cost of the procedure; studies of high methodological quality will be needed before this is the case. Conclusion: The diagnosis of lipedema remains a challenge because of the heterogeneous presentation of the condition and the current lack of objective measuring instruments to characterize it. This review provides a guide to its diagnosis and treatment in an interdisciplinary setting. Research in this area should focus on the elucidation of the pathophysiology of lipedema and the development of a specific biomarker for it
