Lipoedema is a condition of abnormal accumulation of painful adipose tissue, usually in the lower body of women. The disproportionate subcutaneous adipose tissue may negatively impact health-related quality of life (HRQoL). There are currently no patient reported outcome measures (PROM) specifically designed to assess the HRQoL in individuals with lipoedema. The aim of this study was to compare scores on validated lower limb lymphoedema PROMs between females with lipoedema and lymphoedema. In a private lymphoedema clinic in Australia between 1 October 2021 and 22 August 2023, individuals assigned female at birth, aged 18years and older who consented to the entry of de-identified data into a research databank and completed the Lymphoedema Quality of Life tool (LYMQOL-leg) and/or Lymphoedema Symptoms Intensity and Distress Survey (LSIDS-L) for the legs were included in this study. Between group analysis was conducted on 151 participants who were either diagnosed with lipoedema (N=90) or bilateral leg lymphoedema (N=61). Participants with both conditions were excluded. Participants with lipoedema reported significantly higher burden scores for symptoms (p=0.003), appearance (p=0.003) and mood (p=0.011) in the LYMQOL-leg survey when compared to participants with bilateral leg lymphoedema. Participants with lipoedema also reported significantly worse LSIDS-L scores for neurological sensation (p=0.003), biobehavioral (p=0.016) and resource (p=0.008) questions compared to participants with lymphoedema. This study highlights that although females with lipoedema and lymphoedema experience similar symptoms, their experiences differ in specific outcomes that influence their HRQoL. These findings warrant further investigation into the HRQoL concerns of individuals with lipoedema.

Introduction: Although Renal Angiomyolipoma (AML) is a relatively rare entity, it is the most common benign mesenchymal kidney tumour, made up of varying amounts of thick-walled blood vessels, smooth muscle, and adipose tissue. AML occurs either sporadically or in association with Tuberous Sclerosis Complex (TSC). It is often detected incidentally during imaging, though it can present with flank pain, haematuria, or life-threatening haemorrhage, thereby posing diagnostic and therapeutic challenges. Aim: To analyse the clinicopathological features of surgically resected renal AMLs and evaluate the association between radiological and histopathological findings. Materials and Methods: This was a retrospective, crosssectional study conducted in the Department of Pathology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India, in which the clinicopathological features of surgically resected renal AMLs received between January 2014 and October 2023 were studied. Data retrieval, analysis, and manuscript preparation were carried out between December 2023 and March 2024. Clinicoradiological detailsincluding age, gender, clinical presentation, tumour size, laterality, imaging features (fat-rich or fat-poor), presence of haemorrhage, association with TSC/LAM, and type of surgical procedure were retrieved from the hospital information system of the study Institute. The data were analysed using Statistical Package for the Social Sciences (SPSS), IBM Corp, Armonk, NY), version 26.0. Categorical variables are reported as frequencies and percentages, whereas the mean (standard deviations) or medians with interquartile ranges, as appropriate, were used for continuous variables; the associations between categorical variables were analysed using the Chi-square test, where p-value <0.05 was considered to indicate statistical significance. Results: The study included a total of 31 patients, with a mean age of 48.9±16.8 years, and a mean tumour size of 10.0±6.1 cm, resulting in a female-to-male ratio of 2.4:1. Twenty-seven cases were symptomatic, while four were incidental. The major subtype was classical (24), followed by leiomyoma-like (4), epithelioid (2), and lipoma-like (1). Fat-poor AML patients who underwent surgery for Renal Cell Carcinoma (RCC) on imaging were confirmed via histopathology (epithelioid-1, leiomyomalike-3). Bleeding was observed with tumour size ≥6.0 cm (n=10 cases; p-value=0.012). TSC-associated cases (n=3) were younger (mean age-30.3 years vs sporadic-50.4 years) and had a larger mean tumour size of 16.8 cm (vs sporadic-8.8 cm). One patient had concurrent RCC. Conclusion: TSC-associated cases present at a younger age when compared to sporadic AMLs. Fat-poor AMLs can typically mimic RCC on imaging. Larger tumours are known to cause haemorrhage, particularly TSC-associated, from the rupture of pseudoaneurysms. Immunohistochemistry (IHC) for Human Melanoma Black (HMB) 45 and Smooth Muscle Actin (SMA) was useful in establishing a diagnosis in atypical AMLs.

Insulin resistance (IR), commonly associated with obesity, is linked to a range of metabolic and immune-related disorders in the contemporary human population. Nevertheless, it is evolutionary well-conserved, suggesting its potential survival advantages to our ancestors. This review aims to explore the intricate interplay between IR and the immune system as well as its implications for the development of immune-metabolic and allergic diseases in the modern era. From an evolutionary medicine perspective, the longevity of ancient humans relied on energy storage to endure food shortages and effectively activate the immune system against various diseases. Under normal conditions, insulin induces glycogen and triglyceride synthesis in the liver and adipose tissues. However, IR directs more glucose to insulin-independent tissues, such as the immune system, which are critical for survival in adverse conditions. The persistent IR in our current lifestyle promotes low-grade inflammation, accompanied by various metabolic and allergic disorders. Critically, this evolutionary mismatch not only explains disease susceptibility but also informs therapeutic design to target immune-metabolic crosstalk. Moreover, our evolutionary analysis demonstrates that the genomic regions near the PTEN, IL27, and NUPR1 genes could play an important role in this interaction across diverse populations.

Peroxisome proliferator-activated receptor gamma (PPAR-γ) is a key regulator of adipose tissue expansion, coordinating adipocyte physiological differentiation and maturation. In this study we evaluated the PPAR-γ effects of perfluorooctanoic acid (PFOA), a perfluorinated alkylated environmental obesogen, associated with an increased risk of diabetes, during adipogenic differentiation of 3T3-L1 murine cells. In particular, using in vitro monoculture (differentiating preadipocytes exposed to PFOA) or co-culture systems (differentiating preadipocytes in contact with PFOA-induced dysfunctional mature adipocytes) we examined adipocytes morphology and biological functions such as adipogenesis, insulin sensitivity and lipolytic response to adrenergic compounds. Exposure to PFOA (0.1-10μM) promoted adipocyte hypertrophy inducing the formation of larger lipid vacuoles. These effects were also evident in the co-culture system, where paracrine factors released by PFOA-induced hypertrophic adipocytes influenced preadipocytes differentiation. Furthermore, both in the mono-culture and in the co-culture systems, PFOA exposure induced a metabolically unhealthy adipocyte phenotype affecting insulin sensitivity. Finally, findings obtained in mono-culture system evidence that these effects induced by PFOA may be related to its capability to affect lipid metabolism and pro/anti-inflammatory adipokine expression. This study, therefore, draws attention on PFOA as an obesogenic factor promoting adipocyte metabolic dysregulation and dysfunctional paracrine signaling.
