Purpose: We present a case of ocular pathology linked to morbid obesity, emphasizing the role of systemic inflammation in ocular disease and clinical impact of weight loss.
Methods: We report the case of a 49-year-old man with morbid obesity and obstructive sleep apnea who underwent bilateral corneal transplants secondary to keratoconus. For 4 years, he had chronic bulbar hyperemia with progressive blood vessel growth across the graft-host junction, which was treated with chronic topical corticosteroids. Nine years after presentation, he also developed severe papilledema associated with idiopathic intracranial hypertension that proved recalcitrant to treatment with acetazolamide therapy and optic sheath fenestration. Concomitantly, the patient's proinflammatory markers (erythrocyte sedimentation rate, C-reactive protein) were consistently elevated. The patient underwent vertical sleeve gastrectomy, resulting in substantial weight loss. Clinical findings, treatment interventions, and outcomes were documented.Results: The patient experienced marked improvement in corneal graft health and resolution of papilledema following weight loss of 188 pounds. Systemic inflammatory markers, including erythrocyte sedimentation rate and C-reactive protein, also normalized. These findings suggest a correlation between adipose tissue mass and ocular inflammation.
Conclusions: Our patient had rapid improvements in his ocular pathology that correlated with a notable reduction in body fat percentage. We propose that the immunological changes associated with obesity contributed to a proinflammatory ocular state that improved with weight loss. His case highlights that additional research is warranted to explore the etiopathogenic mechanisms of adipokines derived from white adipose tissue on major organ systems, including the eye.

Ovarian cancer (OC) is characterized by high mortality rates due to late diagnosis, recurrence, and metastasis. Here, we show that extracellular signaling molecules secreted by adipose-derived mesenchymal stem cells (ASCs) and OC cells-either in the conditioned medium (CM) or within small extracellular vesicles (sEVs)-modulate cellular responses and drive OC progression. ASC-derived sEVs and CM secretome promoted OC cell colony formation, invasion, and migration while upregulating tumor-associated signaling pathways, including TGFβ/Smad, p38MAPK/ERK1/2, Wnt/β-catenin, and MMP-9.

Adipose-derived regenerative cells (ADRCs) are one of the most promising cell sources that possess significant therapeutic effects. They have now become a main source of cell therapy for the treatment of ischemic diseases due to their easy accessibility, expansion, and differentiation. Additionally, ADRCs can release multiple paracrine factors and extracellular vesicles that contribute to tissue regeneration by promoting angiogenesis, regulating inflammation, alleviating apoptosis, and inhibiting fibrosis.

Osteoarthritis (OA) is one of the most common degenerative diseases in dogs and humans, which can lead to articular cartilage deterioration, chronic pain, and decreased quality of life. The anti-inflammatory, anti-fibrotic, analgesic, and cartilage regeneration properties of mesenchymal stem cell (MSC) therapy provide a new direction for the treatment development of OA in the future. Currently, MSC therapy lacks confirmed ideal sources, dosages, formulations, and specific characteristics.

Different tissues have a normal color spectrum that reflects their cellular composition and/or metabolic features. Similarly, distinct color variations may occur in tissues that have undergone pathologic or nonpathologic changes. Common examples of color changes in domestic animal tissues include red (associated with erythrocytes, hemoglobin, and myoglobin), brown (ferric hemoglobin or myoglobin, suppurative inflammation, lipid oxidation, postmortem autolysis, formalin fixation, neoplasms arising from cytochrome-rich tissues), yellow (hemoglobin and iron degradation, biliary pigment and by-products, carotenes, keratin, necrosis, suppurative or fibrinous inflammation), green (hemoglobin and iron degradation, biliary pigment and by-products, meconium, eosinophilic or suppurative inflammation, oomycete and algal infections), white (lack of blood, adipose tissue and its neoplasms, chylous effusion, necrosis, mineralization, fibrosis, lymphoid tissue, round cell neoplasms), translucent (transudate, cysts), black to gray (hemoglobin and iron degradation, melanin, carbon, tattoos), and blue to purple (poorly oxygenated blood, tattoos).

Background: With the rising incidence of life expectancy, obesity, and tumours, understanding the incretory influence of adipose tissue in tumorigenesis becomes increasingly important. As the adipokines leptin and adiponectin are released by fat tissue, we aimed to analyse the expression of their respective receptors in tumours for which an association with obesity is epidemiologically hypothesised.
Methods: The expression of leptinR and adipoR1 were analysed in cohorts of renal cell cancer (n=391), cervical cancer (n=155), vulvar cancer (n=107), and endometrial cancer (n=90) by immunohistochemistry and correlated with clinicopathological parameters including survival times.
